Dissertations / Theses on the topic 'Academic workload'

Thesis (MTech(Human Resource Management))--Cape Technikon, Cape Town, 2000
This research project investigated the need for a method of determining an equitable workload for academic staffing in higher education. With the possibility of the introduction of a performance management system at the Cape Technikon it became imperative that an agreed, objective and user-friendly method of determining the workload of each academic member of staff be established. The research project established the main parameters of the job of an academic staff member and their dimensions that would influence both the quantity and quality of work produced. They were established based on the views of a panel of educators drawn from a diverse range of disciplines. Using the identified dimensions an algorithm was developed and refined to reflect the consensus views regarding the contributory weightings of each of the parameters' dimensions. This algorithm was tested and refined using a base group of academic staff who were identified by their colleagues as those whose workload could be considered a benchmark for their discipline. The most significant result of the research programme is the agreed algorithm that can form the basis for a performance management system in higher education. The user interface that was developed at the same time reflects the transparency of the system and allows for it to be adapted to the needs of various groups of users or individuals within an organisation. On the basis of this research it has been established that a system for determining an equitable workload which encompasses an extensive range of parameters can be developed using a participatory approach. Using a significant sample of academic staff as a basis, it would appear that the system is valid, reliable, useful and acceptable to academic staff in the context of a performance management system.

A recent trend in consumer and military electronics has been to allow operators the option to control the system via novel control methods. The most prevalent and available form of these methods is that of vocal control. Vocal control allows for the control of a system by speaking commands rather than manually inputting them. This has not only implications for increased productivity but also optimizing safety, and assisting the disabled population. Past research has examined the potential costs and benefits to this novel control scheme with varying results. The purpose of this study was to further examine the relationship between modality of input, operator workload, and expertise. The results obtained indicated that vocal control may not be ideal in all situations as a method of input as participants experienced significantly higher amounts of workload than those in the manual condition. Additionally, expertise may be more specific than previously thought as participants in the vocal condition performed nearly identical at the task regardless of gaming expertise. The implications of the findings for this study suggest that vocal control be further examined as an effective method of user input, especially with regards to expertise and training effects.

Cette thèse engagée à partir des enjeux de la transformation du paysage international de l’éducation supérieure et ses implications au niveau local et national de l’organisation des universités. Basé dans une approche néo-rationaliste des interactions entre acteurs et les systèmes d’enseignement supérieure, le concept gigogne d’arènes académiques et les processus de couplage/découplage, l’analyse se focalise sur le cas d’étude du développement, implantation et ajustement d’un dispositif de calcul des services d’enseignant-chercheur. La méthodologie est basée sur une observation participante de longue durée, l’action-recherche et la méthode d’étude de cas. L’analyse quantitative relative à la transformation de la structure et de la performance des enseignants-chercheurs avec les accomplissements de l’université est combinée avec l’analyse qualitative de données collectées par des entretiens individuels et de groupes conduits avec des enseignants-chercheurs, des membres de la direction de l’université ainsi qu’avec des experts de l’enseignement supérieur malaisien et international. Les analyses conduites démontrent – au niveau de l’organisation universitaire – la capacité de négociation des académiques et du management par rapport à leurs rôles et conditions d’avancement de carrière est central dans l’instrumentation du dispositif de calcul des services. Au niveau national, les analyses soulignent la complémentarité entre institutions d’éducation supérieure privées et publiques. Au niveau international, les analyses soulignent la capacité d’ajustement du système universitaire et des politiques malaisiennes relatives à l’enseignement supérieur et à la recherche pour la régulation de leurs positions dans l’arène académique internationale
This thesis is based on issues concerning the changing landscape of higher education globally and its implication at the local and national levels of the organization of universities. Drawn from the neo-rationalism perspective on the interactions between actors and higher education systems, the ‘gigogne’ concept of the academic arenas and coupling / decoupling processes, the analysis focuses on the case study of the development, implementation and adjustment of academic workload model. The methodology applied is based on long-term participant observation, action research and case study approaches. It is mixing quantitative analysis of the transformation of the academics’ performance and structure with the university’s achievement. On the other hand, this quantitative approach is complimented with the qualitative analysis of data gathered through formal interviews and focus groups, conducted with academics, senior management of the university and as well as experts of the higher education system in Malaysia and globally.Conclusions from the findings demonstrate – at the organizational level of the university - the capability of negotiation of the academics and senior management with regards to their roles and conditions of career advancement is central in the instrumentation of the academic workload system. At the national level, it highlights the complementary action between public and private higher education institutions. At the international level, it stresses on the capability of adjustment of the university organization system and the Malaysian higher education policy to redefine itself in regulating its position at the arenas of international bodies in higher education

This study was conducted in multi-grade primary schools located in Limpopo Province, Capricorn District, Bochum Cluster. The main purpose of the study was to analyse the effects of the principals’ workloads on learners’ academic performance in multi-grade primary schools in Limpopo Province. Twelve schools with the most multi-grade classes were qualitatively sampled from four circuits of Bochum Cluster (Bochum East, Bochum West, Maleboho Central and Maleboho East) as the target for the study. Multi-grade schools are characterised by low learner enrolment. The departmental model of allocating teachers to schools allocates posts according to the number of learners in a school regardless of grades. The school principal is therefore compelled to teach full-time and carry out other related responsibilities such as administration, professional duties and extra-mural activities. Both qualitative and quantitative approaches were employed to achieve the research goals. The study was based on the research question How do principals’ workloads affect learners’ academic performance in multi-grade primary schools in the Capricorn district, Limpopo Province? The study findings, based on interviews, observations and documents analysis have revealed that there are some managerial, leadership, curriculum, teaching and administrative challenges that principals in multi-grade schools are faced with. These challenges collectively contribute to principals’ heavy workload that eventually affect learners’ performance negatively. The researcher therefore concluded that the principals’ workload in multi-grade primary schools have a negative impact on learners’ performance.

In human-computer systems, such as supervisory control systems, large volumes of incoming and complex information can degrade overall system performance. Strategically integrating automation to offload tasks from the operator has been shown to increase not only human performance but also operator efficiency and safety. However, increased automation allows for increased task complexity, which can lead to high cognitive workload and degradation of situational awareness. Adaptive automation is one potential solution to resolve these issues, while maintaining the benefits of traditional automation. Adaptive automation occurs dynamically, with the quantity of automated tasks changing in real-time to meet performance or workload goals. While numerous studies evaluate the relative performance of manual and adaptive systems, little attention has focused on the implications of selecting particular invoking or revoking strategies for adaptive automation. Thus, evaluations of adaptive systems tend to focus on the relative performance among multiple systems rather than the relative performance within a system. This study takes an intra-system approach specifically evaluating the relationship between cognitive workload and situational awareness that occurs when selecting a particular invoking-revoking strategy for an adaptive system. The case scenario is a human supervisory control situation that involves a system operator who receives and interprets intelligence outputs from multiple unmanned assets, and then identifies and reports potential threats and changes in the environment. In order to investigate this relationship between workload and situational awareness, discrete event simulation (DES) is used. DES is a standard technique in the analysis of systems, and the advantage of using DES to explore this relationship is that it can represent a human-computer system as the state of the system evolves over time. Furthermore, and most importantly, a well-designed DES model can represent the human operators, the tasks to be performed, and the cognitive demands placed on the operators. In addition to evaluating the cognitive workload to situational awareness tradeoff, this research demonstrates that DES can quite effectively model and predict human cognitive workload, specifically for system evaluation. This research finds that the predicted workload of the DES models highly correlates with well-established subjective measures and is more predictive of cognitive workload than numerous physiological measures. This research then uses the validated DES models to explore and predict the cognitive workload impacts of adaptive automation through various invoking and revoking strategies. The study provides insights into the workload-situational awareness tradeoffs that occur when selecting particular invoking and revoking strategies. First, in order to establish an appropriate target workload range, it is necessary to account for both performance goals and the portion of the workload-performance curve for the task in question. Second, establishing an invoking threshold may require a tradeoff between workload and situational awareness, which is influenced by the task's location on the workload-situational awareness continuum. Finally, this study finds that revoking strategies differ in their ability to achieve workload and situational awareness goals. For the case scenario examined, revoking strategies based on duration are best suited to improve workload, while revoking strategies based on revoking thresholds are better for maintaining situational awareness.

The objective of this study was to assess low to high levels of Cognitive Workload by measuring heart rate and cortical blood flow in real-time. Four conditions were implemented into a within-subjects experimental design. Two conditions of difficulty and two conditions of trial order were used to illicit different levels of workload which will be analyzed with psychophysiological equipment. Functional Near-Infrared Spectroscopy (fNIRS) has become more prominent for measuring the blood oxygenation levels in the prefrontal cortex of individuals operating in hazardous work environments, students with learning disabilities, and in research for military training. This is due to the fNIR device being highly mobile, inexpensive, and able to produce a high-spatial resolution of the dorsolateral prefrontal cortex during executive functioning. Heart Rate will be measured by an Electrocardiogram, which will be used in concordance with fNIR oxygenation levels to predict if an individual is in a condition that produces low or high mental workload. Successfully utilizing heart rate and blood oxygenation data as predictors of cognitive workload may validate implementing multiple physiological devices together in real-time and may be a more accurate solution for preventing excessive workload.

Academic performance of students is influenced by a combination of several psychosocial factors which include seeking academic help, use of various sources for academic learning, extent of the student seeking academic help, seeing academic help-seeking as a threat to self-esteem, interest in a subject, self-motivation and stress related to academic workload. Therefore, this study aimed to investigate psychosocial factors predicting the academic performance of first-year college nursing students, using a quantitative research method with a descriptive survey design. The population for this study was all first-year nursing students registered at a college of nursing in 2019. An inclusive sampling technique was used to include all 171 members of the student population in the study.

Throughout the many years of research examining the various effects of automation on operator performance, stress, workload, etc., the focus has traditionally been on the level of automation, and the invocation methods used to alter it. The goal of the current study is to instead examine the utilization of various types of automation with the goal of better meeting the operator's cognitive needs, thus improving their performance, workload, and stress. The task, control of a simulated unmanned robotic system, is designed to specifically stress the operator's visual perception capabilities to a greater degree. Two types of automation are implemented to support the operator's performance of the task: an auditory beep aid intended to support visual perception resources, and a driving aid automating control of the vehicle's navigation, offloading physical action execution resources. Therefore, a comparison can be made between types of automation intended to specifically support the mental dimension that is under the greatest demand (the auditory beep) against those that do not (the driving automation). An additional evaluation is made to determine the benefit of adaptively adjusting the level of each type of automation based on the current level of task demand, as well as the influence of individual differences in personality. Results indicate that the use of the auditory beep aid does improve performance, but also increases Temporal Demand and Effort. Use of driving automation appears to disengage the operator from the task, eliciting a vigilance response. Adaptively altering the level of automation to meet task demands has a mixed effect on performance and workload (reducing both) when the auditory beep automation is used. However, adaptive driving automation is clearly detrimental, causing an increase in workload while decreasing performance. Higher levels of Neuroticism are related to poorer threat detection performance, but personality differences show no indication of moderating the effects of either of the experimental manipulations. The results of this study show that the type of automation implemented within an environment has a considerable impact on the operator, in terms of performance as well as cognitive/emotional state.

Similarly, the levels of a gliding angle showed the statistical difference on the performance, workload, and stress (HRV, TLX, and LP: all are p less than] .05). During the flight with 4.5 degree, the pilots showed lower performance with higher workload and stress. However, the levels of the flight experience did not have any influence on the performance, workload, and stress levels (AGPTP, LP, TLX, HRV: all are p greater than] .05). In conclusion, flying in Populated area and flying with a 4.5 degree gliding angle increases the workload and stress level of the pilots. In addition, when the pilots were flying over Populated area at Final Approach to L/D phase, they showed lower performance on tracking the glide path. Based on the results, stresses and workload can have a significant impact on flight performance. Therefore, in order to reduce the workload and stress that can cause human errors, it is highly recommended to carefully examine the impact of new flight procedures on pilot workload and stress before they are implemented.; Since human errors are one of the major causes of flight accidents, the design and operation of the modern aircraft system deals with them seriously. Particularly, the pilot workload on aviation causes human errors. Whenever new procedures are introduced and operated, the aircraft capabilities have been checked in every aspect. However, there has been little study on the impact of the new procedures such as LDLP, SCDA, SATS, and Steep Angle approach on the pilot performance, workload, and stress. In this study, different methods have been tried to understand the relationship between new procedures and the pilots in terms of performance, workload, and stress. The flight factors (e.g. flight experience, gliding angle, and approach area) were examined by the pilot performance, workload, and stress at the "Final Approach to L/D" phase using the single engine Cessna 172R type flight simulator. Five students and five instructor pilots from Embry-Riddle Aeronautical University in Dayton Beach, Florida, participated and they flew under four different simulation tasks of gliding angle and approach area. Their Heart Rate Variability (HRV) and NASA-Task Load Index (TLX) were measured to determine their stress level and subjective workload, respectively. In addition, Landing Performance (LP) data (e.g. landing distance, landing speed) and Above Glide Path Tracking Performance (AGPTP) data were also collected to evaluate pilot performance. As a result, the type of approach area showed a significant effect on pilot performance, workload, and stress determined by ANOVA (HRV, TLX, LP, AGPTP: all are p less than] .05). Flying over "Populated" area (e.g. a large city) resulted in lower pilot performance and higher pilot workload and stress than that over "Non-Populated" area (e.g. a grass field).

ENGLISH ABSTRACT: Change characterises life in the early twenty first century and higher education is no exception. Higher education in South Africa is currently in a considerable state of flux which ultimately is actualised at institutional level. It is academic staff who encounter these changes first hand. Technikon lecturers, in particular, are faced with additional challenges not faced by their university counterparts - they have been called upon to change from a primarily vocational to an academic alignment as a result of technikons being given the right to award degrees. This study conducts a cross sectional survey of academic staff at the Port Elizabeth Technikon to identify their academic workload, with particular reference to their research function. It also seeks to establish whether lecturers consider themselves to be adequately prepared for their research function. A review of the literature reveals that lecturers in higher education are involved in a wide variety of activities, the main ones being teaching, research, service, and scholarship. The literature review also shows that in overseas institutions with missions similar to the technikons, lecturers experienced changes to their workload as a result of the restructuring of higher education. The empirical study shows that academic staff at the Port Elizabeth Technikon have much in common with their international peers in terms of the changes and pressures that have been experienced. The work reality for lecturers at the named institution includes all the traditional elements associated with being academic: teaching, research, service and scholarship. Although research is a new function, this has been positively embraced by most staff and that in most cases lecturers consider themselves to be adequately prepared for this function. The empirical study also shows that more than one third of the respondents do not support the institutional vision of becoming "the first choice technological university of South Africa". Further, the study shows that, in common with other studies, staff were of the opinion that the institution undervalues teaching and that research attracts more recognition and rewards. Finally, it shows that significant numbers of staff work in excess of 50 hours per week and carry teaching loads that are greater than the institutional guidelines. Recommendations are made on the basis of these findings and a further avenue of research is suggested.
AFRIKAANSE OPSOMMING: Verandering is 'n kenmerk van die lewe in die vroee een-en-twintigste eeu en hoer onderwys is geen uitsondering nie. Hoer onderwys in Suid-Afrika ervaar tans 'n besonderse toe stand van veranderlikheid, maar dit is uiteindelik op onderwysinrigtingvlak wat did tot verwerkliking kom. Dit is akademiese personeel wat hierdie veranderings eerstehands ondervind. In die besonder word Technikonpersoneel gekonfronteer met uitdagings waaraan hulle universiteitsewekniee nie blootgestel word nie - daar word van hulle vereis om van 'n primere beroeps-orientering oor te skakel na 'n akademiese ingesteldheid as gevolg van die feit dat technikons die mandaat verkry het om grade toe te ken. Hierdie studie het 'n opname onder akademiese personeel aan die Port Elizabethse Technikon gedoen om vas te stel wat die personeel se akademiese werkslading is, met besondere verwysing na hulle navorsingsfunksie. Die ondersoek poog ook om vas te stel of lektore van mening is dat hulle genoegsaam voorberei is vir hulle navorsingsfunksie. 'n Literatuuroorsig toon dat lektore in hoer onderwys betrokke is by 'n bree verskeidenheid aktiwiteite, waarvan die belangrikste onderrig, navorsing, dienslewering en vakkundigheid (scholarship) is. Die literatuurstudie toon ook dat in ander lande aan inrigtings met soortgelyke doelstellings as die technikons, lektore veranderings in hulle werksladings ondervind het as gevolg van die herstrukturering van hoer onderwys wat teen die einde van die twintigste eeu plaasgevind het. Die empiriese studie toon dat akademiese personeel aan die Port Elizabethse Technikon met betrekking tot die veranderings en druk wat ondervind word veel in gemeen het met hulle intemasionale ewekniee, Die realiteit in die werkplek vir lektore by genoemde inrigting sluit al die tradisionele elemente in wat verband hou met die akademie: onderrig, navorsing, diens en vakkundigheid (scholarship). Alhoewel navorsing 'n nuwe funksie is, is dit deur die meerderheid personeel positief aanvaar en in die meeste gevalle is lektore van mening dat hulle vir hierdie funksie voldoende voorberei is. Die empiriese studie toon ook dat meer as een derde van die respondente nie die institusionele visie om "die eerste-keuse tegnologiese universiteit van Suid-Afrika te wees" ondersteun rue. Voorts toon die studie soos ook in ander studies, dat personeel van mening was dat die inrigting onderrig geringskat en dat meer erkenning en belonings aan navorsing gegee word. Laastens toon dit dat 'n beduidende aantal personeellede meer as 50 uur per week werk- en onderrigladings dra wat meer is as die riglyne van die inrigting. Op grond van hierdie bevindings word aanbevelings gemaak en 'n verdere navorsingsrigting voorgestel.

Thesis (MTech (Design))--Cape Peninsula University of Technology, 2016.
Student workload is measured by the time it takes to complete the learning activities. This study determines the workload of Design students by determining the time spent on in- and out-of-class learning activities of a Design course at a higher education institution in Cape Town. The Design learning process typically engages students in several of the following learning activities: problem solving; research and development of ideas; and the mastering of various skills relating to visual communication. These afore-mentioned activities span the duration of a design project crossing the boundaries between subjects. The teaching of Design occurs in various locations such as the design studio and site visits. It therefore becomes difficult to unpack the time spent on in- and out-of-class learning activities for the purposes of workload calculations as prescribed and defined by higher education institutions and educational policies worldwide. Workload is a significant variable in the curriculum and is of importance in the quality of the teaching and learning process in higher education. An analysis of the literature determined that student workload could be viewed as objective workload (notional hours), the perceived/estimated hours worked (as highlighted in student course experience surveys) or the actual hours reported over a period of time. The resulting discussions focused on the comparability of students‟ workload to the expected notional hours and grades. Thus far none of the previous studies considered time allocation or the workload of the Design student or Design education. Can it be assumed that notional hours apply to all subject fields and therefore, the time allocated to in- and out-of-class learning activities should be equal as well? A timesheet diary was used to determine the time spent on learning activities. The population consisted of Interior Design students. Participants indicated what they were doing in the class as well as the amount of time spent on learning activities outside of timetabled hours. This study determined that the time reported for text-based subjects aligned with the notional hours and timetabled hours. On the other hand, a drawing-related subject – because of project-based learning and individual crits – is allocated more timetable hours, which does not align with the notional hours. The contact time thus appears to be high in comparison to the notional hours and results in an overloaded timetable (28hrs). However, it was found that the individual average for in-class time (14hrs 54min) reported by the participants aligns with the notional hours. Further analysis of the reported time revealed that class duration should be considered in the light of the teaching methods. In addition the average workload in this study of 53hrs 7 min per week exceeds the notional 40 hours per week. The average workload was compared to the participant‟s term results, the notional 40-hours, and the 50% required for passing a subject. This revealed that participants whose workload exceeded 40 hours were likely to pass. This supports the notion that provision should be made in the curriculum to afford students the time to meet the learning outcomes. However, due to the small sample available the impact of workload on student retention and student success could not be determined.

A growing body of research indicates the importance of coping strategies when an individual responds to environmental demands. Community concern about the maladaptive responses of some adolescents, limited research with this age group, and the development of a new Australian measure of adolescent coping provided the impetus for this study. The study was conducted with 141 female students in their final year of High School. They completed the Adolescent Coping Scale (ACS) in March, and measures of anxiety and self-confidence in November, just before major external examinations. Behavioural rating scales were completed by parents and teachers. The adolescent group reported frequent use of coping strategies which research indicates are likely to be effective, and relatively little use of ineffective strategies. When facing a severe academic stressor, they were self-confident but reported very high levels of anxiety, which was cognitive rather than somatic in focus. The few students whose ACS scores showed relatively high use of ineffective and low use of effective coping strategies were identified as "At risk". When compared with a contrasting sub-group, the "At-risk" students were significantly more anxious and less self-confident. There was no evidence that parents or teachers were aware of the adolescents' high levels of anxiety. The findings provide support for the predictive validity of the ACS, and have implications for helping adolescents cope with stress and developmental demands. Further research directions are suggested.

Aim: An audit of the workload of an Acute Care Surgery Unit in a Tertiary Academic Hospital and an assessment of the impact on this Unit by the closure of a busy Community Hospital. Background: The primary mission of the Acute Care Surgery service is to provide timely surgical assessment, operative and/or non-operative management of the acutely ill non-trauma surgical patient. Both locally and internationally, fewer surgeons are perusing general practice, opting instead for subspecialty training, with no or only minimal time spent in emergency surgical care. This is demonstrated for example by evidence that some colorectal surgeons refer diseases of the appendix to the general surgeon, reflecting the narrow point of care that is being practiced in certain fields of surgery. In many cases acute care surgery has been described as a multidisciplinary approach involving Emergency and Trauma Surgery, and Critical Care Medicine.(1-3) In South Africa the rules and regulation by the Health Professions Council stipulates the requirement of training and qualifying as a General Surgeon, before pursuing Fellowship training in a field of subspeciality. As treatment paradigms shift and surgical emergency disease management evolves, we need properly trained surgeons that are willing to pursue the optimal emergency care (surgical or non-operative) for specific conditions in patients presenting with these acute surgical emergencies.(2,4) Groote Schuur Hospital (GSH) is privileged in its provision of an Acute Care Surgical Unit (ACSU) that functions in a tertiary environment and is affiliated with the University of Cape Town (UCT), the leading ranked University on the African Continent. The ACSU in GSH has 28 dedicated beds, and functions as a secondary and tertiary level General Surgery Unit excluding all acute trauma care. Provision is also made for the management of primary level surgical diseases. A neighboring surgical referral hospital, GF Jooste Hospital (GFJH), has 90 dedicated surgery beds. It is a Community Hospital, which caters for primary and secondary level diseases. Acute care is also given to tertiary level trauma and emergency surgical diseases. The unit at GFJH will be closing to allow for a reconstruction of the building, and thus the patient population will require access to alternate facilities whilst awaiting the reopening. A subset of these patient will have to be accommodated at GSH.

Auditory preemption theory suggests two competing assumptions for the attention-capturing and performance-altering properties of auditory tasks. In onset preemption, attention is immediately diverted to the auditory channel. Strategic preemption involves a decision process in which the operator maintains focus on more complex auditory messages. The limitation in this process is that the human auditory, or echoic, memory store has a limit of 2 to 5 seconds, after which the message must be processed or it decays. In contrast, multiple resource theory suggests that visual and auditory tasks may be efficiently time-shared because two different pools of cognitive resources are used. Previous research regarding these competing assumptions has been limited and equivocal. Thus, the current research focused on systematically examining the effects of complexity and timing of communication interruptions on visual detection tasks. It was hypothesized that both timing and complexity levels would impact detection performance in a multi-task environment. Study 1 evaluated the impact of complexity and timing of communications occurring before malfunctions in an ongoing visual detection task. Twenty-four participants were required to complete each of the eight timing blocks that included simple or complex communications occurring simultaneously, and at 2, 5, or 8 seconds before detection events. For simple communications, participants repeated three pre-recorded words. However, for complex communications, they generated three words beginning with the same last letter of a word prompt. Results indicated that complex communications at two seconds or less occurring before a visual detection event significantly impacted response time with a 1.3 to 1.6 second delay compared to all the other timings. Detection accuracy for complex communication tasks under the simultaneous condition was significantly degraded compared to simple communications at five seconds or more prior to the task. This resulted in a 20% decline in detection accuracy. Additionally, participants' workload ratings for complex communications were significantly higher than simple communications. Study 2 examined the timing of communications occurring at the corresponding seconds after the visual detection event. Twenty-four participants were randomly assigned to the communication complexity and timing blocks as in study 1. The results did not find significant performance effects of timing or complexity of communications on detection performance. However the workload ratings for the 2 and 5 second complex communication presentations were higher compared to the same simple communication conditions. Overall, these findings support the strategic preemption assumption for well-defined, complex communications. The onset preemption assumption for simple communications was not supported. These results also suggest that the boundaries of the multiple resource theory assumption may exist up to the limits of the echoic memory store. Figures of merit for task performance under the varying levels of timing and complexity are presented. Several theoretical and practical implications are discussed.

World-wide, there has been a large increase in tertiary student numbers, not entirely matched by funding increases. Consequently, instructors are faced with large, diverse classes, and find themselves struggling to provide adequate assessment and prompt feedback, two quantities critical in an effective learning environment. Personal computers and the Internet can help solve this problem. The aim of this study was to develop, implement and validate a Web-based software package that, through providing practice and assessment opportunities, improved student learning and reduced marking and related mundane aspects of instructor workload. At the start of the study, such a package already existed in prototype form: OASIS (Online Assessment System with Integrated Study). As the study progressed, this software package was first fully rewritten and then repeatedly modified. OASIS delivers individualised tasks, marks student responses, supplies prompt feedback, and logs student activity. Staff can deliver sets of practice questions and assessments to students: assessments may involve different questions for different students, not just numerically different versions of the same questions. Given my role as teacher, the traditional research ideal of observing without affecting the research environment was both impossible and unconscionable. In particular, since preliminary evidence suggested that OASIS did enhance student learning, I could not adopt a ‘two groups’ approach to the research, with one group using OASIS while the other did not. Instead, an action research methodology was seen as most appropriate for my double role of teacher and researcher.
This methodology enabled me, in the light of my findings, to continuously modify the learning environment and enhance student learning. The action research proceeded through a spiral of one-semester cycles of planning, acting, observing and reflecting. To maximize rigour, the research ran through eight cycles over four years and involved considerable triangulation. OASIS itself collected much quantitative data. Further data were collected via interview, survey, email and informal discussion from three groups: current students, postgraduates and academics. My colleagues provided alternative perceptions and interpretations, as did Physics Department academics who were using OASIS, and an external academic who interviewed academics and investigated the implementation of OASIS. Perhaps surprisingly, academics had generally adopted OASIS to promote student learning rather than to decrease their own workloads. In some cases workloads were reduced; however, where OASIS assessments augmented rather than replaced existing traditional assessments, workloads actually went up slightly. All instructors who used OASIS reported enhanced student learning and wished to continue using it. Student surveys, interviews, focus-group discussions and informal feedback showed that students found the software easy to use and considered that it helped them improve their skills and understanding. OASIS questions were preferred over textbook questions. Students commonly requested OASIS to be available in more of their areas of study. In general students wanted hints or model answers though some argued against their provision.
The majority of students were enthusiastic about the use of OASIS for practice, and activity logs revealed that they did use OASIS extensively. These logs also revealed the motivating power of assessments: typically half the online practice activity took place in the last 36 hours prior to assessments. Interviews provided further interesting insights into the ways different students approached their studies and assessments. However, students did voice concerns about the validity of OASIS assignments, noting their peers could rely on the efforts of others to score highly in these. A number of steps were carried out in an attempt to defuse these concerns, including: disabling OASIS practice during assignments, basing assignments on previously unseen questions, and providing different assignment questions to different students. While this study has achieved the goal of developing, implementing and validating OASIS, many future opportunities exist. OASIS may be used in schools as well as universities. Non-numerical questions, where answers may be somewhere between right and wrong, are possible. OASIS can also be used to deliver concept inventories to students to support research into concept acquisition and retention.

The aim of this study was to develop, implement and validate a Web-based software package that, through providing practice and assessment opportunities, improved student learning and reduced marking and related mundane aspects of instructor workload. At the start of the study, such a package already existed in prototype form: OASIS (Online Assessment System with Integrated Study). As the study progressed, this software package was first fully rewritten and then repeatedly modified. OASIS delivers individualised tasks, marks student responses, supplies prompt feedback, and logs student activity. Staff can deliver sets of practice questions and assessments to students: assessments may involve different questions for different students, not just numerically different versions of the same questions. Given my role as teacher, the traditional research ideal of observing without affecting the research environment was both impossible and unconscionable. In particular, since preliminary evidence suggested that OASIS did enhance student learning, I could not adopt a ‘two groups’ approach to the research, with one group using OASIS while the other did not. Instead, an action research methodology was seen as most appropriate for my double role of teacher and researcher.This methodology enabled me, in the light of my findings, to continuously modify the learning environment and enhance student learning. The action research proceeded through a spiral of one-semester cycles of planning, acting, observing and reflecting. To maximize rigour, the research ran through eight cycles over four years and involved considerable triangulation. OASIS itself collected much quantitative data. Further data were collected via interview, survey, email and informal discussion from three groups: current students, postgraduates and academics. My colleagues provided alternative perceptions and interpretations, as did Physics Department academics who were using OASIS, and an external academic who interviewed academics and investigated the implementation of OASIS. Perhaps surprisingly, academics had generally adopted OASIS to promote student learning rather than to decrease their own workloads. In some cases workloads were reduced; however, where OASIS assessments augmented rather than replaced existing traditional assessments, workloads actually went up slightly. All instructors who used OASIS reported enhanced student learning and wished to continue using it. Student surveys, interviews, focus-group discussions and informal feedback showed that students found the software easy to use and considered that it helped them improve their skills and understanding. OASIS questions were preferred over textbook questions. Students commonly requested OASIS to be available in more of their areas of study. In general students wanted hints or model answers though some argued against their provision.The majority of students were enthusiastic about the use of OASIS for practice, and activity logs revealed that they did use OASIS extensively. These logs also revealed the motivating power of assessments: typically half the online practice activity took place in the last 36 hours prior to assessments. Interviews provided further interesting insights into the ways different students approached their studies and assessments. However, students did voice concerns about the validity of OASIS assignments, noting their peers could rely on the efforts of others to score highly in these. A number of steps were carried out in an attempt to defuse these concerns, including: disabling OASIS practice during assignments, basing assignments on previously unseen questions, and providing different assignment questions to different students. While this study has achieved the goal of developing, implementing and validating OASIS, many future opportunities exist. OASIS may be used in schools as well as universities. Non-numerical questions, where answers may be somewhere between right and wrong, are possible. OASIS can also be used to deliver concept inventories to students to support research into concept acquisition and retention.

The focus for this thesis has been on the management of academic workloads, stimulated by surveys highlighting high levels of stress in the sector. To get some appreciation of the subject and its context a literature synthesis was conducted revealing that the subject has received little critical attention. As a consequence the research methodology involved theory building, rather than hypothesis testing, and Grounded Theory has been used for this. Case studies were conducted in eight diverse universities involving interviews of a range of staff in each. Two non-educational case studies were also carried to get wider insights into potential approaches. In all fiftynine interviews were conducted. Case and cross case analyses were carried out on particular aspects, these were then mapped, using cognitive mapping, to give a visual representation of the relationships at work. A second more focused literature synthesis was carried out to widen understanding of the findings and from there an initial model was developed for workload allocation processes. This model was re-examined using the case study material and through a further longitudinal case study. Conclusions were then drawn, highlighting contributions to theory, practice, and methodology, together with recommendations for future work. The main elements of the findings are that practice in the sector varies considerably between and within UK universities, but that drawing on the elements of good practice seen it has been possible to propose the features of a broad, generic approach. This approach stresses the importance of both the social and technical aspects of the issue and the necessity of actively addressing the reciprocal relationships between individual, department and university levels.

Thesis (M. Tech. (Public Management)) -- Central University of Technology, free State, [2014]
The primary aim of the proposed study is to investigate the technical problems affecting the efficiency and effectiveness of District Hospitals in the Free State Province. The proposed research therefore stands to contribute to the existing body of evidence on the efficiency and effectiveness of health care services, with regard to the existing problems in the health sector such as high staff turnover, facilities with lack of appropriate equipment, unmanageable workload, lack of appropriate infrastructure, a high absenteeism rate and low morale of the employees in the public health institutions. Therefore the study will identify potential shortcomings that are compromising the efficiency and effectiveness of the district hospitals. The findings of the study will be used to address some of the identified problems and also to describe how progress can be measured. The outcomes of this study are intended to raise important issues and to assist management of the Free State Department of Health to address the challenges that are affecting the functioning of the district hospitals. The findings will also assist the relevant managers in planning and implementation of policies that will address inequalities and problems as highlighted in the study. It will also create opportunities for shared responsibilities that management and the staff need to resolve jointly.

The overall aims of this study were to investigate the prevalence, extent and explore the experiences of Nurse Academics in Australia in relation to job satisfaction and burnout. Over the last three decades, university teaching has become increasingly challenging and stressful; this has affected the quality of life of academics. This is evidenced by the rapidly changing working conditions and stress experienced globally among university academics Consequently, the relationship between academics and their workplace are very demanding, more stressed, followed by lack of resources and eventually leading to burnout. Burnout is defined as a psychological syndrome emerging as a prolonged response to chronic interpersonal stressors on the job. Since, the move of nurse education into the university sector in Australia in the mid 1980’s, the stress and demands placed upon Nursing Academics has risen and intensified dramatically. Although the literature is replete about the work experiences among university academics very little research has been carried out to investigate the prevalence and explore the experiences among nurse academics, particularly within Australia (Bittner, & Bechtel, 2017) in relation to occupational stress and burnout. This research study utilized a mixed methods design, specifically, the sequential explanatory model A two phased approach was utilized. In phase one 234 nurse academics completed the survey comprised of the MBI, MSQ and demographics. In phase two, 19 participants were interviewed. The conceptual framework that underpins this study is influenced by the Job- Demands Resource Model (J-DR Model). In phase one, participants were drawn from a cross section from novice to experienced academics. 50% of participants reported low levels of burnout, whilst the other 50% reported either moderate or high levels of burnout. Out of these 50% who experienced burnout about 20% of respondents experienced a high-level of burnout. Similarly, 50% of the participants experienced low levels of job satisfaction and this correlated significantly with high levels of the total burnout scores (r = -0.56). Within the qualitative component, the main themes included a lack of work life balance, incivility towards staff, increasing workloads, challenging students, lack of recognition, negative workplace culture, lack of awareness of the importance of political astuteness, and lack of leadership skills and difficulty with retention of newly appointed staff. Many participants also expressed being threatened, felling intimidated, and unfairly treated coupled with facing personalities who were driven by power struggles. Overall, there appeared to be a sense of powerlessness, that participants were relatively powerless and unable to change their lot. Although personal resilience provided a buffering effect for some of the participants and acted as a protective factor against stress and burnout it is not well understood. This research study contributes to the ongoing body of work on the experiences of nurse academics globally and gives a further insight and understanding of the personal experiences of occupational stress and burnout among Australian nurse academics. However, a few potential limitations to this study should be noted. The study sample was only selected from within Australian universities which may limit the global generalisation of the findings and it was undertaken at an only one time point. Occupational stress leading to burnout is still considered an important factor and predictor of job satisfaction and intention to leave among Australian nurse academics. Effective mentoring and leadership styles that promote a nurturing work environment, a sense of belonging, being valued, heard, and recognised, are areas of priority. Strategies and policies should be revised for greater inclusiveness, academic freedom, institutional autonomy, and a better work-life balance. Further work is needed that examines the specific types of support systems that nurse leaders could initiate to reduce job stress leading to burnout. Ongoing evaluation is crucial to ensure the appropriateness, efficacy, and effectiveness of the support systems. The findings have important global implications in terms of recruitment and retention of nurse academic.

Objetivo: Este estudio explora la manera que el personal docente e investigador (PDI) gestiona la interfaz trabajo-familia. Para ello, primero se definirá el trabajo del profesorado. ¿Qué implica ser profesor en la universidad? Segundo, ¿qué tipo de conflicto trabajo-familia (CTF) es común en el ejercicio de esta profesión? Tercero, ¿qué prácticas lleva a cabo el profesorado con tal de reducir el CTF y promover la facilitación o enriquecimiento trabajo-familia? Y cuarto, ¿qué diferencias existen según las variables tipo de contrato, etapa vital, y género? De acuerdo con estos objetivos, la revisión de literatura abordará los siguientes temas: 1) interfaz trabajo-familia (conflicto y facilitación), 2) sobrecarga de trabajo, 3) conceptos relacionados, incluidos el burnout y el engagement, 4) el marco teórico demandas-recursos (estrategias de afrontamiento), y 5) el trabajo del profesor universitario en el contexto español. Diseño y Metodología: Esta tesis adopta un enfoque cualitativo en el estudio de los antecedentes, consecuencias y estrategias de afrontamiento de la sobrecarga y del conflicto trabajo-familia. Un cuestionario respondido por 146 profesores y profesoras de universidades españolas pregunta abiertamente si ellos perciben que les falta, basta o sobra tiempo para realizar su trabajo, y cómo lo viven. Adicionalmente, se llevaron a cabo en Barcelona 17 entrevistas y 2 grupos de discusión. El trabajo de campo se completó entre primavera de 2007 y 2010. Los datos obtenidos de los cuestionarios, grupos de discusión y entrevistas fueron asignados como documentos primarios en el programa Atlas.ti para someterlos a un análisis de contenido temático. Resultados: El carácter multi-propósito del trabajo del profesorado, que combina actividades de docencia, investigación y gestión, es el principal factor de la sobrecarga de trabajo, y ésta, a su vez, es el principal factor de CTF. Además del triple perfil del profesorado, muchos están pluriempleados y algunos tienen participación política. Las tareas de gestión son vistas como labores para las cuales el profesorado no ha sido preparado, por lo que ella es fuente de estrés, burocracia y sobrecarga de trabajo que va en desmedro de la calidad de la docencia e investigación. Esta tesis hace un llamado a una mejor distribución de los recursos y del personal administrativo, para que éste actúe como soporte a las tareas nucleares de la universidad: docencia e investigación. Además de la sobrecarga cuantitativa del profesorado, también existe sobrecarga cualitativa, relacionada particularmente a dos áreas: desarrollo profesional y promoción, y control y satisfacción por el trabajo bien hecho. La carga laboral no es algo nuevo, pero en el pasado esta carga no había sido tan alta. Por ejemplo, hace veinte años atrás había menos presión social y presión autoimpuesta entre los profesores de la universidad. Había menos evaluación profesional, menos competencia por una plaza fija, y los profesores estaban menos expuestos a la comunidad académica global. Así, la sobrecarga laboral, definida en este estudio como la percepción de falta de tiempo para realizar el trabajo, es identificada como el mayor estresor en el ámbito familiar. Los antecedentes de la sobrecarga laboral se clasifican en tres: antecedentes personales, sociales y organizacionales. Los factores personales incluyen la presión autoimpuesta y desarrollo en la trayectoria académica, conflicto familia-al-trabajo, y deficiencia en autoeficacia. Para esta muestra, los factores sociales sólo incluyen la presión social. Y finalmente, los factores organizacionales consisten en sobrecarga de rol, falta de recursos/personal, distribución de tareas y horarios, y cambio, burocracia y sobrecarga de información. Por otra parte, las consecuencias de la sobrecarga laboral pueden clasificarse en tres categorías: consecuencias en la salud física y psicológica, en la familia, y en el trabajo. La primera categoría incluye distrés psicológico e impacto emocional, e impacto en la salud y hábitos saludables. Consecuencias familiares se refieren al conflicto trabajo-a-la-familia, y al impacto en el tiempo personal y social. Por último, las consecuencias laborales abarcan la calidad del trabajo, satisfacción, participación, motivación y clima laboral. Entonces, ¿qué hacen los profesores para reducir el CTF? Este estudio considera sólo la una demanda del ámbito laboral: la sobrecarga de trabajo cuantitativa. Del ámbito no remunerado, considera las demandas familiares (tareas de cuidado y ocio de familiares) y demandas domésticas (como la limpieza, compras, presupuesto y finanzas del hogar). Los recursos (estrategias de afrontamiento) han sido clasificados en tres tipos: absorción de la carga, reducción de la carga, y reducción del distrés, creando así una taxonomía particular al profesorado español. Muchas estrategias se superponen y se usan tanto para afrontar la sobrecarga de trabajo como las demandas doméstico-familiares, simultáneamente. Generalmente, los profesores afrontan de manera diferente según el ámbito de procedencia de la demanda. Sin embargo, el impacto que las estrategias utilizadas tendrán sobre el otro ámbito son continuamente consideradas. Esto les ayuda a decidir, aunque en muchas ocasiones no hay elección. Ciertas estrategias, como las orientadas a absorber la carga de trabajo, parecen contradictorias, pues ellas crean o intensifican el conflicto con el cuidado de los hijos. En otras palabras, estrategias de aumentar la jornada laboral tiene consecuencias en el conflicto temporal, en detrimento de otras demandas que compiten por ese tiempo, del equilibrio trabajo-familia, y del bienestar general. Inevitablemente, el estrés surge cuando las demandas exceden los recursos disponibles. Para el estrés, los profesores tienen estrategias de reducción del distrés que apoyan y amortiguan los efectos de las consecuencias para absorber y reducir la carga. Esta tesis identifica dos estilos o perfiles extremos de afrontamiento entre profesores que perciben una alta carga de trabajo: los “sobrecargados y quemados” y los “sobrecargados y engaged”. Los primeros tienen un estilo de afrontamiento reactivo y preferencias por estrategias de segmentación, mientras que los segundos afrontan proactivamente y tienden a integrar el trabajo y la familia. Las estrategias orientadas a absorber la sobrecarga laboral, especialmente la práctica de trabajar más horas, promueven la cultura del presentismo. Es decir, mientras los profesores trabajen más horas, esa práctica se vuelve normal y deseable, por lo que luego se hará más difícil ejercer estrategias en el sentido contrario. Esto cuestiona el poder de agencia del docente para actuar con libertad. Se identifican diferencias entre algunas variables como el tipo de contrato (fijo o temporal), la etapa vital y el sexo/género. El trabajo academic parece ser más difícil para mujeres jóvenes, sin plaza fija, y personas con hijos pequeños o el primer hijo. Limitaciones: Se reconocen varias limitaciones: 1) el carácter transversal de su diseño, 2) la existencia de un único codificador/analista, y 3) la coincidencia del período de trabajo de campo (2007-2010) con el apogeo de la crisis económica y el potencial impacto de ésta en los datos. Implicaciones: La tesis señala unos aspectos de las condiciones de trabajo del profesorado universitario español (y por las referencias de la literatura, del personal académico considerado a escala global) que constituyen importantes factores de riesgo psicosocial, y por tanto unos puntos de referencia para las correspondientes políticas preventivas. Se hace un llamado a utilizar como variable independiente la jornada laboral efectiva (consecuencia de las estrategias personales para absorber la carga), en vez de las horas de trabajo reflejadas en el contrato, o la carga de trabajo objetiva para estudiar el campo trabajofamilia. La razón de esto es que las horas de trabajo más allá de la jornada normal de trabajo inciden y contribuyen fuertemente en el conflicto trabajo-familia. Además es una medida subjetiva. Contribución: El valor de esta tesis reside en enfocar la investigación en el campo trabajo-familia sobre una profesión, país y contexto contingente particular: el personal docente e investigador en España. Los resultados demuestran que algunas estrategias personales de afrontamiento para absorber la carga laboral (como aumentar la propia jornada laboral) predice el CTF. Dos perfiles de estilos extremos se han identificado, lo cual ayuda a entender por qué aumentar las horas de trabajo tiene algunas veces consecuencias negativas y otras no. Palabras Clave: Interfaz trabajo-familia, sobrecarga de trabajo, estrategias de afrontamiento, académicos.
Background: In our knowledge society, it is common to experience work without boundaries. Some occupations such as self-employed professionals, physicians and academics can work longer hours, which leads to work-family conflict (WFC) (Byron, 2005; Frone, 2003; Eby, Casper, Lockwood, Bordeaux and Brinley, 2005). Time flexibility has been offered by employers as the most common prescriptive approach to providing a balance between work and life for their employees (Cully, Woodland, O’Reilly and Dix, 1999; Dex and Smith, 2002; Hogarth, Hasluck and Pierre 2000). However, problems concerning coping with work and domestic responsibilities remain especially acute for employees with caring responsibilities and especially women (Major, Klein and Ehrhart, 2002; Schwartz and Scott, 2000). But what happens when the work environment is flexible? Is it flexible enough to partially resolve WFC? Purpose: The general goal of the present study was to explore how professors manage the work-home interface. Therefore, the study aims to define professors’ work and specify how work can cause WFC, to identify the type of WFC events the exercise of this profession can entail, and to examine the strategies employed to reduce WFC and enhance work-family facilitation (WFF). According to the aims, relevant literature was reviewed on the following issues: 1) workfamily (life) interface (conflict and facilitation), 2) work overload, 3) related working concepts, including burnout and engagement, 4) the demands-resources framework (coping strategies), and 5) the professor’s work and the Spanish context. Design/methodology/approach: A qualitative approach was used to investigate the work-family (WF) interface antecedents, outcomes and coping strategies. A survey administered to 146 female and male Spanish university professors enquired if they perceive a lack of, a sufficient amount of, or a surplus of time to perform their work. Seventeen interviews and two focus groups were also conducted in Barcelona. The fieldwork was conducted during spring 2007 and 2011. A questionnaire, focus group and interview transcripts were entered as primary documents into the Atlas.ti software for qualitative analysis, where a Thematic Content Analysis was conducted. Findings: A unique set of WF interface antecedents, outcomes, coping strategies and linkages to other factors were identified in the professors’ responses. Some professors have more than one job, some because they wish to, and others because they need to. Some may also have a presence in the political arena. Participants consider that the main task contributing to work overload is dedication to service, which means time and energy that comes from the teaching and researching realms. Only a few professors like to perform service tasks. The majority feel frustrated when obliged to carry out service tasks, since they have not been prepared to do so. This is also related to the lack of staff and resource complaints. The Teaching and Research Academic Staff (Personal Docente e Investigador, PDI) feel a lack of control when performing service tasks. However, these tasks also constitute unpaid work and it is simply their turn to do service work. Service position or tasks are also notorious for their excess paperwork. Professors that perceive a lack of time usually identify some areas of their working life in which they require more time. Two fields were detected: professional development and career advancement and control and satisfaction concerning work well done. Was a heavy workload always experienced? Twenty years ago, there was less social pressure and less self-imposed pressure. Professors were subject to fewer appraisals and less competition, and people were less exposed to the global academic community. Work overload (as a perceived lack of time to complete work) is the main stressor in the family domain. Professors’ work overload is due to the very nature of the profession and the multi-purpose nature of their work: teaching, research and service. Antecedents can be classified into three main categories: personal, social and organizational antecedents. Personal antecedents include self-imposed pressure and career development, family-to-work conflict (FIW), shortcomings in personal organization and shortcomings in self-efficacy. For the project sample, social antecedents only concern social pressure, and organizational antecedents comprise role overload, lack of resources/staff, task and schedule distribution, unforeseen events, change, bureaucracy and information overload. On the other hand, outcomes of work overload can be classified into three categories: physical and psychological/health outcomes, family consequences, and work consequences. The psychological/health outcomes category features the following aspects: psychological distress and emotional impact and impact on health and healthy habits. Family consequences consist of work-to-family conflict (WIF) and impact on social and personal time. Finally, work consequences involve work quality, satisfaction, participation, motivation and working climate. What do professors do to reduce WFC? For the purposes of the study, only one demand of the work domain has been considered: work overload (related to teaching, research and service activities). From the unpaid work domain, family (tasks and leisure related to kinkeeping) and home activities (i.e. housework, grocery shopping, budgeting and management of household finance) have been considered. The resources (coping strategies) are classified into three main coping styles: load absorption, load reduction and distress reduction, thereby creating a particular taxonomy of coping strategies for Spanish academics. Many strategies overlap and are employed to cope with work overload and family/home demands simultaneously. People cope differently according to the demand domain. However, professors evaluate the consequences generated by a certain strategy in one field on the other field. This helps them decide. However, on many occasions, there is no choice. This situation sometimes makes strategies seem counterproductive. For instance, there are some strategies for absorbing work overload (e.g. working longer hours at the office, working on Saturdays at the university or working at night) that create or intensify conflict with childcare. In other words, the behavioral-based strategy of working long hours has consequences on time-based conflict, to the detriment of competing demands and the work-family balance. In particular, the strategy of working longer hours than usual is an antecedent of work-family conflict. Stress inevitably surfaces when professors perceive that demands exceed the resources available. Professors have their own supportive coping strategies for stress, which are classified under the style known as distress reduction. Coping strategies aimed at absorbing workload, especially those related to exceeding working hours and having to work at home, reverberate in an increase of professors’ WF conflict and a decrease in perceived well-being. The coping style of absorbing the work overload encourages a culture of presenteeism. In other words, the practices change the structure (i.e. working culture), meaning that professors have little freedom to act, thus calling coping agency into question. Two extreme profiles have been identified (i.e. the “overloaded and burned-out” and the “overloaded and engaged”) in coping with work overload according to reports of experience. The relationship held by both profiles with the perception of work-family interface has been demonstrated. Engaged participants are involved in strategies that integrate the work and family domain and proactive coping (engaged professors are more likely to tackle demands while relieving pressure), and the burned-out are less flexible with work and home boundaries (segmentation) and have a preventive coping style. Changes in three variables are particularly relevant in professors’ work. The first is related to whether they have a temporary contract or tenure. The second concerns their life stage, and the third, the gender role. Academy seems to be harder for young women, not-tenured, and with young children. Limitations: The current research is not without its limitations. The cross-sectional research design implies that the postulated relationships between work overload and work-family conflict and vice versa cannot be interpreted causally. The study has also only had one analyst/encoder. A weakness of the study is that it is limited by a convenient sample of academics at one major university, as interviews and focus groups were conducted in Barcelona, and it also represents higher educated Spanish employees. The extent to which the findings can be generalized to employees in other cultural contexts with a lower level of education is unknown. The processes of conducting interviews and focus groups were carried out in Barcelona, and it is assumed that the study is representative of the situation among professors across the country given that the questionnaires were distributed across the entire country. In order to maintain the privacy of study participants, specific data regarding their discipline/profession was not collected. Therefore, future work should include information concerning academic disciplines/professions as the area in which one works may have a different work-family culture. Theoretical Implications: The purpose of this study was to contribute to the literature on both the work-family interface and work overload. Firstly, this study provides the antecedents and outcomes of work overload in a particular occupation and culture, namely, academics in Spain. This study identifies and describes the strategies for coping with work overload and it also determines three styles and two modes of coping. Results demonstrate the qualitative relationship between work overload and WFC. Secondly, this study contributes to coping theories in WF literature. It affords the specific coping strategies employed by professors at public universities in Spain in order to struggle with work and family/home demands. It was found that strategies are more effective when used together, and that some practices to absorb work overload may lead to WFC, which is consistent with emergent research. Practical implications: WF scholars have studied work overload in terms of objective working hours rather than focusing on perceived work overload (and lack of time to carry out the work). This study clearly shows the linkages among antecedents, outcomes and coping strategies regarding work overload and family-to-work conflict. Therefore, researchers are encouraged to use perceived work overload or lack of time as independent variables. Ideally, to make a step forward, researchers should address the coping strategy of working beyond normal hours to tackle workload as a variable affecting the WF interface instead of objective working hours or workload, as was done in the past. This study clearly shows the linkages among antecedents, outcomes and coping strategies concerning work overload and family-to-work conflict. Researchers are encouraged to use perceived work overload or lack of time as independent variables. Furthermore, professors’ work overload outcomes have a devastating impact on WF balance and well-being, as well as on work quality and stress that subsequently reverberates in student learning. Originality/value: The main contribution of this research consisted of setting WF research in a particular profession and context: teaching and research professors in Spain. It also recognizes that particular spillover coping strategies are predictors of WFC. Two extreme profiles for coping with the WF interface were identified, which facilitate the understanding of the reasons why working long hours sometimes has negative outcomes whereas, in other situations, it does not. Keywords: Work-family interface, spillover, work overload, coping strategies, academics.

Submitted in fulfilment of the requirements of the Master of Management Sciences in Administration and Information Management, Durban University of Technology, Durban, South Africa, 2016.
A number of studies have been conducted in relation to academic workload in higher education and many have noted a marked increase in workload over recent decades. However, fewer have specifically investigated the increase in the administrative component of an academic’s workload, and none have focussed on the current support given to academics by their secretaries in the context of a South African University of Technology. All academics require sufficient time to perform their teaching, research and community outreach duties satisfactorily, while Universities of Technology make additional demands on their academic staff in relation to such aspects as Work Integrated Learning, maintaining contacts with industry and new research requirements. The literature indicates that many feel that they are unable to cope or to cope adequately and that universities often do not understand the burden of the different tasks/activities they perform. The purpose of this case study was therefore to investigate the administrative workload experienced, and the support given, to academics at the Durban University of Technology. It specifically investigates whether the institution of a workload model for the university as a whole would be supported, and would be effective, in addressing equity and transparency issues in academic workload and thus in improving academic retention and research output for the university as a whole. This study used a mixed method approach involving three questionnaires administered to academics, their secretaries, and to senior management. In addition, semi-structured interviews were conducted with some senior academic staff. The results of the research indicate that the great majority of academic staff members experience a heavy administrative workload and that many believe they are doing more than they expected at the time of their appointment. While the secretaries were better informed as to the nature and extent of the administrative duties expected of them, many also felt that they are doing more than they expected and both groups indicated strongly that there is a lack of transparency and equity between different workloads performed by different individuals. Over ninety percent of both academic and secretarial staff believed that a workload model would assist in ensuring a fairer balance in the work performed, but significant individual comments indicated the difficulties and drawbacks which should also be taken into account and the consequent need for flexibility and ongoing consultation with staff, before the imposition of such a model. The results also revealed that there was considerable uncertainty amongst respondents as to the current existence of a workload model. It was, however, established that the university is planning to implement a workload model across all six faculties and that a member of the academic staff, Mr Greg Parrott, has been tasked to develop the relevant software. He is in the process of collecting the information needed. Contact was made with Mr Parrott and information exchanged with him. It is hoped that the data gathered in this study will serve to support this initiative. Following an in-depth analysis of the results, this study recommends wide consultation over the implementation of the model and the employment of a pilot phase to iron out any problems. Flexibility within the model and ongoing consultation are also recommended. The study further recommends that academic departments should consider making greater use of WIL students from the discipline of Office Management who, as part of their work experience, can work closely with secretaries in departments which require additional secretarial assistance. Additional part-time assistance, possibly from retired academics, for specifically academic administrative duties might also be considered.

Recent advances in courtship theory emphasize day-today interaction and the environment in which interaction takes place as critically important in the understanding of relationship development. The purpose of this study was to determine the influence of college course assignments on time spent in relationship activities and, similarly, the influence of time spent in relationship activities on relationship satisfaction. As college couples are often the subjects of relationship studies, consideration of the college environment seemed both appropriate and overdue. The sample consisted of 35 serious dating couples in which both partners were full-time students. A telephone survey methodology was developed so that couples could report coded relationship behaviors both conveniently and confidentially. Data were collected twice a week for 8 1/2 weeks during winter term 1987 at a large northwestern university. Results indicated: (1) previous, current, and up-coming course assignments were influential regarding reported time in selected relationship activities, and, in general, tended to increase time in activities; (2) when assignments decreased relationship activity, men's assignments were more influential. Women's assignments, particularly previous assignments, were found likely to increase relationship activity. Regarding the influence time spent in activities had on relationships satisfaction, the data indicated that time spent eating together and in affectionate behavior were activities that increased relationship satisfaction. Discussion centered on the "interpersonal process" framework of relationships development and on the timing of course workload on relationships. Conclusions suggested the academic environment does have an effect on dating relationships and that this effect may be similar to work and family issues that society as a whole is facing.

This study aimed at exploring the level of job satisfaction among academic staff members in Ethiopian public universities. For this purpose, a conceptual framework incorporating group of constructs, namely university policies and support, working conditions, student achievement, and demographic factors was developed based on the literature reviewed in the study. A descriptive survey research design was employed in the study to collect and analyse quantitative data obtained from participants. Clustered and systematic random sampling techniques were used in the study to choose 400 academic staff members from eight public universities. A questionnaire comprising closed- and open-ended questions, and Likert scale items was adapted in order to gather data from the participants. Descriptive and inferential statistical procedures were used to analyse the relationships between all the study constructs with the help of IBM SPSS, version 25. The study revealed that there were significant differences among different demographic groups, and positive relationships between job satisfaction and its defining constructs. The study also found that most of the academic staff members were dissatisfied with their jobs. Female academic staff members were more significantly dissatisfied with students‟ discipline policy, university governance and support, their salary, workload, communication, and students‟ achievement than male academic staff members. Male academic staff members were, however, more significantly satisfied with the promotion policy and more significantly dissatisfied with reward than the female academic staff members. The study revealed that academic staff members significantly differed in the level of job satisfaction corresponding to their age and qualification. The study also indicated that academic staff members significantly differed in the level of job satisfaction corresponding to their work experience and academic rank. Significant correlations between the eight constructs and job satisfaction of academic staff members were also found in the study. Finally, the study recommended directions for policy amendment and implications for practice and future research relevant to the issue under study.

Measures of workload have been developed on the basis of the various definitions, some are designed to capture the multi-dimensional aspects of a unitary resource pool (Kahneman, 1973) while others are developed on the basis of multiple resource theory (Wickens, 2002). Although many theory based workload measures exist, others have often been constructed to serve the purpose of specific experimental tasks. As a result, it is likely that not every workload measure is reliable and valid for all tasks, much less each domain. To date, no single measure, systematically tested across experimental tasks, domains, and other measures is considered a universal measure of workload. Most researchers would argue that multiple measures from various categories should be applied to a given task to comprehensively assess workload. The goal for Study 1 to establish task load manipulations for two theoretically different tasks that induce distinct levels of workload assessed by both subjective and performance measures was successful. The results of the subjective responses support standardization and validation of the tasks and demands of that task for investigating workload. After investigating the use of subjective and objective measures of workload to identify a universal and comprehensive measure or set of measures, based on Study 2, it can only be concluded that not one or a set of measures exists. Arguably, it is not to say that one will never be conceived and developed, but at this time, one does not reside in the psychometric catalog. Instead, it appears that a more suitable approach is to customize a set of workload measures based on the task. The novel approach of assessing the sensitivity and comprehensive ability of conjointly utilizing subjective, performance, and physiological workload measures for theoretically different tasks within the same domain contributes to the theory by laying the foundation for improving methodology for researching workload. The applicable contribution of this project is a stepping-stone towards developing complex profiles of workload for use in closed-loop systems, such as human-robot team interaction. Identifying the best combination of workload measures enables human factors practitioners, trainers, and task designers to improve methodology and evaluation of system designs, training requirements, and personnel selection.

The challenge being experienced by higher education to attract and retain talented academics, particularly black staff, motivated this particular study. The challenge has been experienced by the higher education sector since the democratic dispensation in South Africa in 1994 with minimal published research having been undertaken in this specific field. In addition, it did not appear that there was a tangible solution or strategy by education leaders to respond to the crisis facing higher education. Meanwhile, seasoned academics, particularly white staff, continue to retire taking with them invaluable intellectual capital at a loss to academe. The challenges cited by academics for leaving academe do not augur well for the academic profession as a career of choice particularly for young black potential academics. The present study adopted a mixed methods approach using data collection instruments associated with both the quantitative and qualitative research paradigms. Talent management typically consists of four pillars of intervention viz. attraction, retention, development and deployment. The first part of the doctoral thesis focussed on the analysis of literature and empirical documents found in three of the four talent management pillars, namely attraction, retention and development. Deployment is not practical in the academic sector. The second part of the doctoral thesis focussed on a sample of academics in particular colleges or faculties at three South African universities. In the process following the implementation of the survey and interviews, ideas and themes were identified in the data. The research study presented a recommendation in response to the challenge to attract and retain academics, particularly black staff, with a particular emphasis on the development of black academics at lower levels. This is within the broader context of the academic employer value proposition. The study recommends that to attract and retain talented academics, particularly black staff, education leaders should focus on investing resources into the management of talent inherent in black academics at lower levels.

The study explored factors that affect learner academic achievement in Physical Sciences in Limpopo rural secondary schools. The motivation for the research was based on the high failure in Physical Sciences in South African schools. The new Curriculum Assessment Policy Statement (CAPS) has brought changes in the teaching and learning of Physical Sciences such as assessment processes, methodology and new content. It was worth pointing out that the achievement of Physical Sciences learners gives an indication of the effectiveness and efficiency of Physical Sciences teaching and learning. Therefore, identifying the factors entails important issues which are of great relevance to the way Physical Sciences should be taught in schools to improve learner academic achievement. The primary question was “Which factors impact on learners’ academic achievement in Physical Sciences in Limpopo rural secondary schools?” In order to answer this question a qualitative approach and qualitative survey design were used and individual interviews were carried out with Physical Sciences teachers, principals, parents and curriculum advisors. Data was further collected through focus group interviews with Physical Sciences learners. Purposeful sampling was used to identify the participants. Data analysis in this research was aimed at giving appropriate meaning to the views of the Physical Sciences teachers, Physical Sciences learners, principals, curriculum advisors and parents on factors affecting learner academic achievement in Physical Sciences. The data was audio-recorded, transcribed and printed. The interview transcriptions were organised into themes by coding. The coded data was used to form the true analysis of the activity system by identifying the purpose of the activity in order to get clarifications. This included the context of the Physical Sciences teaching and learning and learner academic achievement. The results according to the perceptions of Physical Sciences teachers, Physical Sciences learners, principals, curriculum advisors and parents showed that the main issues of high failure rate are lack of adequate resources, teacher effectiveness, lack of motivation, high teacher-learner ratio, workload, discipline of learners, supervision of teachers, parental involvement, management and leadership skills, and appropriate teaching methods. Recommendations for practice and policy are suggested and the indication was that provision of common tasks to teachers and formation of subject committees decreases the workload. The availability of resources allows learners to do practical work and improve performance. The goal was to engage learners in challenging and stimulating tasks with appropriate help from the teachers to improve achievement. In order for the teacher to provide assistance to the learners there must be maximum teacher-learner ratio. Effective supervision ensures that teachers and learners are punctual, which will ensure maximum use of available teaching time and timely completion of the work schedules or pace setters. A smaller number of learners per class could result in improved performance in Physical Sciences. It is important for principals to instil discipline in learners. The support and value of NGOs to assist in sharing workload by carrying out experiments in secondary schools was acknowledged.

This book explores the module design experiences and practices of academics employed within one UK university, and during a period of social and economic change in which university staff are designing and delivering curricula for changing student populations, with different profiles and expectations than previous generations. The book raises issues such as why, in a climate of reduced resources, staff increase their own workloads by re-writing lectures to accommodate changing student needs, and how institutional practices that are used to encourage curriculum innovation are often having a perceived opposite effect. It will appeal to academic staff, students of higher education studies, and policy-makers within the education sector.

The main hallmarks of the novel problem-based curriculum are self-directed, student-centred learning, clinical reasoning, small group tutorials and the facilitation of learning in an integrated way. These features differ significantly from the traditional curriculum which is teacher-centred, discipline-based and more content orientated. The innovative programme was implemented at the University of Transkei with a view to improving medical education. In this study, the perceptions of second year medical students regarding the implemention of and transition to the new curriculum, was assessed, as part of the evaluation of the curriculum. The results showed that students had grievances about the overwhelming volume of information they had to cover, time constraints, examination methods and bias of tutors towards their own subjects. Nevertheless, they considered the innovation to be favourable, exciting, relevant to life and to future tasks, and more motivating than the traditional curriculum.
