This system is based on theCeva/Menelaus method for proving theorems. This formalization is performedusing Δ-complexes, so the areas of logic, geometry and algebraic topologyare combined in the dissertation. The axiomatic sequents of the system stemfrom 2-cycles of Δ-complexes. The Euclidean and projective interpretations ofthe sequents are defined and the decidability and soundness of the systemare proved. Patterns for extracting formulation and proof of the incidenceresult from derivable sequents of system are exemplified. The procedure fordeciding if set of n sextuples represent an axiomatic sequent is presentedwithin the thesis.

Full textAbstract:
Mentorship and previous leadership experiences have been found to serve as factors that contributed to counseling professionals becoming leaders. Historical influences, life philosophy, identity, and resilience also shaped leaders and guided leadership practices. Critical incidents (e.g., difficulties or successes in organizational management or addressing ethical issues); however, are also significant experiences that are considered “a powerful source of counselor development.” To date, researchers have explored critical incidents in counseling graduate students’ training. However, there were no studies that have focused exclusively on the role of critical incident experiences of nationally appointed or elected counselor leaders. Thus, it was not necessarily clear how such incidents contribute to or impede the development of counselor leaders. Therefore, the aim of this grounded theory study was to qualitatively explore critical incidents using the Critical Incident Technique (CIT). The researcher conducted semi-structured interviews to explore experiences that have influenced the counselor leaders’ development, practices, and effectiveness.
Findings from this study represent the experiences of fourteen national leaders in the counseling profession. The present study contributes to the growing literature on counseling leadership and counseling leadership development. Specifically, the Model of Counselor Leaders’ Development and Meaning Making of Significant Experiences (MCLD) seeks to explain counselor leaders’ experiences in leadership. The overall premise of this model is that the following five components are interconnected and ultimately lead to outcomes within the organization and with the leaders’ own growth and development: Personal Factors, Professional Factors, Culture and Climate of Organization, Leader’s Knowledge and Skills, and Decision-Making and Problem-Solving.

Full textAbstract:
This thesis presents a comprehensive study of incidence calculus, a probabilistic logic for reasoning under uncertainty which extends two-value propositional logic to a multiple-value logic. There are three main contributions in this thesis. First of all, the original incidence calculus is extended considerably in three aspects: (a) the original incidence calculus is generalised; (b) an efficient algorithm for incidence assignment based on generalised incidence calculus is developed; (c) a combination rule is proposed for the combination of both independent and some dependent pieces of evidence. Extended incidence calculus has the advantages of representing information flexibly and combining multiple sources of evidence. Secondly, a comprehensive comparison between extended incidence calculus and the Dempster-Shafer (DS) theory of evidence is provided. It is proved that extended incidence calculus is equivalent to DS theory in representing evidence and combining independent evidence but superior to DS theory in combining dependent evidence. Thirdly, the relations between extended incidence calculus and the assumption-based truth maintenance systems are discussed. It is proved that extended incidence calculus is equivalent to the ATMS in calculating labels for nodes. Extended incidence calculus can also be used as a basis for constructing probabilistic ATMSs. The study in this thesis reveals that extended incidence calculus can be regarded as a bridge between numerical and symbolic reasoning mechanisms.

Full textAbstract:
Accidents, and incidents of faults and failures are an unavoidable reality for even moderately complex systems. Accidents, though unfortunate events, also provide an opportunity to uncover vulnerabilities and latent errors in systems. In this vein accident and incident analysis plays an important role in improving system dependability and robustness. Incidents when analysed individually often seem to be caused due to isolated reasons. However, when incidents are analysed in the context of other incidents in the broader domain then patterns begin to emerge between them. These patterns may indicate basic and underlying reasons for incidents, known as root causes. The practice of analysing a number of incidents together is called Multi-incident analysis. The state of the art of multi-incident analysis is dominated by quantitative methods that mostly use statistical analysis to find correlations between concepts. These methods are limited in their ability to identify systemic reasons for accidents, faults, and failures. To overcome this shortcoming, qualitative methods are sometimes used in incident analysis; in an effort to acquire a better understanding of the incident space. However, these methods do not provide any methodological support to guide the qualitative analysis towards the discovery of root causes. This thesis presents the Grounded Incident Fault Theories (GIFTs) method for multi-incident analysis. GIFTs is a qualitative multi-incident analysis method that provides methodological support to identify root causes and mitigation strategies by analysing past incident in a particular domain. GIFTs is a synthesis of two methods: The Incident Fault Tree (IFT), which is a method for incident analysis and documentation; and The Grounded Theory Method (GTM), which is a qualitative analysis method for building theories and discovering insights about phenomenon through the aggregation of data. GIFTs merges these two methods in a way that the whole is greater than the sum of its parts. In GIFTs the Incident Fault Tree guides the Grounded Theory process to efficiently identify the most important concepts with respect to understanding and mitigating faults and failures.

Full textAbstract:
Responding to critical incidents in school communities has become an established part of the practice of educational psychologists (EPs). Despite this the EP professional journal literature is sparse, the last major study being conducted by Houghton in 1996. Within a mixed methods design this study aimed to explore various aspects of EP practice in response to critical incidents. Firstly, critical incident policy and EP journal literature was examined to provide a definition of 'critical incident'. Secondly, following a review of relevant literature separate online questionnaires were developed and completed by 39 Principal EPs and 50 EPs to provide an overview of practice in response to critical incidents. Thirdly, semi-structured interviews were carried out with a number of practicing EPs. Within an 'espoused theory / theory in use' framework, the interviews sought to examine EP practice in relation to theory espoused in the relevant professional and policy literature. The definition generated, which remained robust throughout the study, suggested a systemic impact of critical incidents as well as the impact on individuals and groups. Questionnaire data indicated that critical incident training and policy are now widespread. Debriefing was commonly carried out by EPs following critical incidents and supervision for EPs remained a salient issue. Evaluation of the critical incident work described was largely through informal consultation with school staff. The thematic analysis of interview data yielded several factors and theories in the practice of EPs that had received relatively little attention in policy and EP journal literature. Consideration of the wider trauma literature led to further suggestions of ways in which these may be applied to EP practice. It is argued that greater consideration of the systemic impact of critical incidents coupled with an awareness of the application of salutogenic and positive psychology approaches can provide balance to conceptualisations based on the negative sequelae for individuals and groups.

Applying selected concepts of organizational theory to the Mayaguez incident of 1975 leads to a more comprehensive understanding of events and more accurate lessons learned. Application of organizational theory to the Mayaguez incident demonstrates the decision processes at the executive level left the military operation vulnerable to failure. Henry Mintzberg's structural contingency model and Lee Bowman and Terrence Deal's frames model are used and are applied to executive-level decisions. The rationale behind focusing on the executive level is twofold: first, it is where final critical decisions are made and second, military operations cannot take place without an executive-level authorization. The Mayaguez crisis was rife with potential pitfalls and, though President Ford was equipped with an organization of intelligent, competent personnel, the result was unnecessary loss of life. Publicly, the operation was a success and President Ford the savior of the Mayaguez crew. To the military, the operation was an embarrassment because of failures in the organizational structure and decision making. Application of organizational theory provides an avenue for analysis of the military operation within the Mayaguez rescue.

Full textAbstract:
O presente estudo teve como objetivo modelar e quantificar o efeito do processo de atribuição causal dos incidentes críticos, positivos e negativos, na qualidade da relação Cliente-Empresa em momento posterior à sua ocorrência. Foi utilizada uma amostra longitudinal oriunda do estudo da satisfação e lealdade no âmbito do ECSI-Portugal, que avalia a qualidade da relação Cliente-Empresa antes e depois da ocorrência dos incidentes críticos. A amostra foi constituída por 416 consumidores de serviços de empresas instaladas em Portugal-Continental, que descreveram 245 incidentes críticos positivos e 141 incidentes críticos negativos. Foi aplicada a modelação de equação estrutural pelo método Partial Least Squares - PLS para teste de modelos na amostra geral de cada tipo de incidente crítico e de subamostras com modelos alternativos de situações de equilíbrio e desequilíbrio baseadas no princípio de equilíbrio da Teoria da Atribuição Causal (Heider, 1958).
Os resultados apresentados neste estudo validam as teorias existentes na literatura, que relacionam a satisfação e a lealdade sustentável à sobrevivência das empresas prestadoras de serviços. Conclui-se que manter a satisfação cumulativa é a chave para a qualidade da relação Cliente-Empresa e para manter os comportamentos leais dos consumidores de serviços tanto na ocorrência de incidentes críticos positivos quanto negativos. Conjuntamente, a investigação traz novos conhecimentos sobre estes comportamentos diante de situações de equilíbrio e desequilíbrio na relação Cliente-Empresa. Pode referir-se que, em ambientes onde a qualidade anterior da relação Cliente-Empresa é mais positiva, ocorra o incidente crítico negativo e a relação é mais duradoura, os consumidores de serviços tendem a atribuir a responsabilidade deste incidente crítico a causas externas; ABSTRACT:
The objetive of this study was to model and quantify the effects of the causal attribution of critical incidents, positive and negative, on the Customer-Company relationship quality. This goal was accomplished through the analysis of a longitudinal client sample, drawn from a satisfaction and loyalty study within the scope of ECSI-Portugal. Consequently, it was possible to evaluate the quality of the Customer-Company relationship before and after the occurrence of critical incidents. The sample consisted of 416 service consumers of Portuguese companies, who described 245 positive critical incidents and 141 negative critical incidents. Structural equation modeling was applied to the data with the use of the Partial Least Squares (PLS). Structural models for the general sample of each type of critical incident were validated. Based on the balance principle from the Attribution Theory (Heider, 1970), alternative models for subsamples with balance and imbalance situations were also evaluated.
The results achieved in this study validate the existing theories, which relate satisfaction and sustainable loyalty. It is concluded that maintaining cumulative satisfaction is key to the quality of the Customer-Company relationship and to maintain customers’ loyal behavior, both when positive and negative critical incidents occur. Addittionaly, the present research contributes with new knowledge about those behaviors in balance and imbalance situtions of Customer-Company relationship. It may be noted that in environments where the previous Customer-Company relationship quality is more positive and longer and a negative critical incident occurs, service consumers tend to attribute the responsibility of this critical incident to external causes.

The think aloud method has been used in this research to generate data that
reveals the thoughts of participants of a study while they are performing tasks. The
pioneers of this method, Simon and Ericsson, have provided a method to analyze the
data so as to obtain meaningful results. However, this analysis method is complicated
and time consuming. Most researchers use some form of categorization to perform their
analysis. Critical incidents were used to categorize the data gathered in the tests
conducted as part of this research. This research proposed the use of tenets of Activity
Theory while performing data analysis so that the cultural and environmental aspects
that influence task performance are identified and addressed as part of the analysis. A
data analysis template was created that directs the analyst to follow activity theory while
performing the analysis. Sample data was gathered using the Think Aloud Method. The
results obtained after analyzing this data using the proposed Activity Theory Based
method were compared with those obtained when the same data was analyzed using a
representative traditional method of analysis. The research included positive critical
incidents, negative critical incidents and level of severity of negative critical incidents as
the dependent measures. No significant differences were found between the two
methods based on these dependent measures. Task type had a significant effect on the
number of positive and negative critical incidents identified.Master of Science

Empresas e organizações sociais têm um papel cada vez mais importante no mercado brasileiro. Essas organizações - sejam elas com ou sem fins lucrativos –têm como objetivocausar um profundo e positivo impacto social.Ambas enfrentamtambém o mesmo desafio: financiar as suas operações. Recentemente, dois modelos inovadores de financiamento, o fundo de venture capitalVox Capital e o fundo de empréstimo social SITAWI, entraram no mercado brasileiro para solucionar esse desafio. Este estudo analisa ambos os fundos,associando o problema do financiamento de empresas e organizações sociais às teorias tradicionais de negócio. Mais especificamente, por meio de um estudo de caso,é avaliado se o risco de agência (agency risk) explica as práticas e o designcontratual utilizados pelos fundos. A pesquisa é baseada num estudo de Alemany e Scarlata (2010) sobre a estruturação dos negócios de fundos filantrópicos de capital empreendedor (PhVC, na sigla em inglês) na América do Norte e na Europa. Uma definição chave desse estudo é que organizações sem fins lucrativos, ao contrário daquelas com fins lucrativos, estão sujeitas a uma restrição de distribuição de lucros. Embora Alemany e Scarlata (2010) tivessem descobertoque parceria (stewardship), mais do que o problema de agência (agency problem), explica a estrutura dos negócios dos fundos PhVC, as implicações do presente estudo de caso para o Brasil são diferentes. Os resultados sugerem que o problema de agência,mais do que a parceria,descreve adequadamente os contratos analisados de financiamento. Detectou-seque cláusulas contratuais não foram apenas usadas para mitigar o risco de agênciaresultanteda ausência de uma restrição de distribuição de lucros, mas também para reger as estruturas cooperativas com organizações sem fins lucrativos. No caso de SITAWI, a restrição dos destinatários de fundos de distribuir lucros provou-se uma ferramenta efetiva para alinhar os interesses entre os financiadores e os destinatários dos fundos. Apesar daimplicação da presença de parceria, os contratos do fundo social contiveram cláusulas geralmente usadas para reduzir o risco de agência. No caso de Vox Capital, os destinatários dos fundos eram empresas com fins lucrativos, portanto não sujeitas à restrição de distribuição de lucros. O modelo de negócio de Vox Capital é organizado para impedir qualquer incidência potencial do problema de agência. Ambos os fundos, independentemente da estrutura jurídica dos beneficiários destes fundos, evidenciaram o intuito de garantir a aplicação de práticas de negócio utilizadas pelas empresas tradicionais do setor corporativo em vez daquelas utilizadas no setor social.

Full textAbstract:
Fire Service commanders work in a very dynamic environment. This research investigated the process they use to make sense and thereby develop understanding of situations during the response to a large-scale emergency. In previous research that investigated decision-making and situation awareness in real-life environments, the need for commanders to understand an incident is emphasised. This research aimed to generate new insights into the process individuals follow to build and improve situational understanding. An exploratory project phase was used to focus the research. Data from emergency exercises and interviews resulted in the design for the main study regarding application domain, data sources and methodological issues. For the main study, records of publicly available interviews with senior officers of the New York Fire Department on their experience of the response to the events at the World Trade Center on September, 11 2001 were analysed. Findings include six variations of the sensemaking process structure, which is characterised by distinct stages. A following investigation into why these stages occur took a theory-building approach and revealed two insights. First, process stages are tied to seven hierarchical but interlinked levels of understanding. Second, three groups of underlying mechanisms trigger process stages: four cognitive factors, eight needs to understand and three situational factors. The mechanisms occur in different combinations across process variations and have varying explanatory power. This study contributes to knowledge on the process of building and improving situational understanding and its link to understanding. A micro-level view of the sensemaking process is provided, showing the specific understanding that is gained and evolves along its stages. The view of sensemaking is extended from understanding what is going on and what can be done to include understanding performance of action. A review with experts revealed that findings adequately reflect the thinking of commanders during incident response and might have practical relevance for training and command support.

Full textAbstract:
Over the past decade the Fire & Rescue Service (FRS) has attended an average of 67,000 residential dwelling fires a year, resulting in an annual average of 14,000 casualties and 450 deaths in the UK (DCLG, 2007). Anthropogenic Accidental Dwelling Fire (AADF) is not a random phenomenon, and through the use of spatial and temporal pattern analysis, it can be shown to be disproportionately concentrated in areas that share common social, economic and environmental characteristics. Developing robust theory and methodology will improve the understanding of the nature of the problem and the ability to effectively target resources to areas of greatest need. This thesis presents the development of a new theoretical model of Anthropogenic Accidental Dwelling Fire incidence, bridging the theory gap in the existing research literature. The theoretical model developed identifies the component factors of potential domestic activity fire risk and the key role of trigger events, by act or omission, that combine to significantly increase the risk of fire within a dwelling. Spatial and temporal analysis of the distribution of over 17,000 individual AADF incidents, from the Greater Manchester area, was conducted utilising the nationally comprehensive and consistent ward level Indices of Deprivation 2000 (IMD) and the Enumeration District (ED) level SuperProfiles geodemographic typology. The analysis revealed statistically significant variation in the profile of incident distribution, operationally valuable to the FRS and of major policy importance. An AADF Routine Activities Time Classification was produced and an analytical methodology developed to derive temporal profiles for incidents across both area characteristic classifications and ignition categories. The AADF spatial-temporal ignition profiles were shown to vary significantly, providing valuable new empirical evidence in support of the implementation of the theoretical model and the utilisation of the methodology developed, informing both strategic policy and service delivery management of a modernising Fire & Rescue Service. A comprehensive national survey of FRS was undertaken and the results are critically reviewed, providing a snap shot of the data, systems, analysis and skills of the FRS, exploring the potential capacity of the organisation to utilise theory based research with evidence lead targeting and resource allocation. A practical application of the use of the IMD as a proxy for Fire & Rescue Service demand is then developed and tested, addressing a perverse incentive within the Standard Spending Assessment used to fund the FRS. A simple weighted model was over fitted to the known incident distribution of the case study area of Greater Manchester. The IMD group weightings derived were then extrapolated to national population distributions within IMD classes and the SSA recalculated. Finally the principal findings of the research are presented, the outcomes critically reviewed, policy implications discussed and recommendations made.

Full textAbstract:
This volume begins with a meta-ethnography which synthesises some documented experiences from teachers who had been involved in 'critical incidents' resulting in bereavement, loss and grief within their school communities. The final synthesis of the experiences from a selection of papers was presented in a line of argument synthesis (LOA) as a model which attempts to illustrate three discrete elements which interacted with one another - the nature of the incident; the psycho-social conflicts negotiated by the teacher and the elements of their professional identity which were drawn out through the being involved in the incident. The final section of this volume presents a piece of empirical research which was undertaken to either confirm, change or refute the tentative model presented in the meta-ethnography. The initial research from the meta-ethnography suggested that the issue and underlying feelings of how to best support a child or colleague following a critical incident was a powerful but unspoken concern for many teachers. The empirical research used a series of semi-structured interviews to give participants an opportunity to explore their experience of being involved in a critical incident. The data from the interviews was then analysed using the grounded theory of Strauss and Corbin (1990) which allowed for a more inductive approach to the participants' data and the tentative model. The new data from the analysis confirmed and changed aspects of the tentative findings of the meta-ethnography model with each of the three elements being renamed Critical Incident Expression, Core Conflict and Core Identity. The empirical data also changed the way that the model functioned, moving from a linear progression to a fluid and interactive one. The model is proposed as tool for facilitating teachers' discussion of their experience of critical incidents. Between these two sections, I have presented a chapter where the theoretical underpinnings and epistemological decisions of the research are discussed alongside the practical and ethical considerations of undertaking original work.

Full textAbstract:
Diabetes is a major risk factor for the development of cataract [3,14,20,22]. In this thesis, we create a model that allows us to understand the incidence of one disease in the context of another; in particular, cataract in the presence of diabetes. The World Health Organization's Vision 2020 blindness-prevention initiative administers surgeries to remove cataracts, the leading cause of blindness worldwide [24]. One of the geographic areas most impacted by cataract-related blindness is Sub-Saharan Africa. In order to plan the number of surgeries to administer, the World Health Organization uses data on cataract prevalence. However, an estimation of the incidence of cataract is more useful than prevalence data for the purpose of resource planning. In 2012, Dray and Williams developed a method for estimating incidence based on prevalence data [5]. Incidence estimates can be further refined by considering associated risk factors such as diabetes. We therefore extend the Dray and Williams model to include diabetes prevalence when calculating cataract incidence estimates. We explore two possible approaches to our model construction, one a detailed extension, and the other, a simplification of that extension. We provide a discussion comparing the two approaches.

Full textAbstract:
Stroke is one of the leading causes of death and disability in Sweden and in the Western world. Despite this, stroke with focus on elderly is a field where few studies have been conducted from a gender and socioeconomic perspective. The objectives in this thesis were to analyse from a gender, age and socioeconomic perspective how women were affected by stroke compared with men. The focus was on what it meant for elderly women and men to live with stroke and to explore various gender constructions among men and women. The study also included aspects such as incidence, medical treatment and case fatality after stroke. Both quantitative and qualitative methods were used. During a two-year period (15 October 2000–14 October 2002), uniform information was collected for all cases of first-ever and recurrent (>28 days) stroke occurring in people of all ages living the region of Umeå, admitted to the University Hospital. Five different registers were used to achieve maximum coverage; the Riks-Stroke (RS) register, the Hospital Discharge Register (HDR), the Cause of Death Register, the northern Sweden WHO MONICA study, and one case-finding study in nursing homes and homes for elderly performed for this thesis. For the qualitative study a maximum variation sampling procedure was used to retrieve participants for in-depth interviews in a follow-up study. Nine women and seven men were interviewed about their experiences of treatment and care after suffering a stroke, as well as about their perceptions and experiences of help from others (health care personnel, relatives and home help personnel). The first-ever incidence of stroke was higher among low-educated than high educated men and women. Our study showed that there was an education-related age-dependent difference in stroke incidence, where elderly women had the highest incidence of stroke. The 28-day case fatality was shown to be associated with low educational level in patients above 75 years, after controlling for sex, risk factors and acute care variables. The elderly stroke patients experienced subordination in their contacts with health care personnel and the medical context. The participants used different ways to negotiate in the subordinate position, and some of these negotiations were interpreted as being gendered. We have also shown how the elderly stroke patients minimized their own needs of help, strove for independence and accepted help. The men and the women differed in their perceptions and experiences of help from others. Also, the participants expressed multiple types of needs. The elderly stroke patients’ perceptions and experiences of help from others must be studied in relation to their life circumstances and expectations from society. Further analyses of the patients’ perceptions and experiences of help from others were interpreted as being different examples of constructions of masculinities and femininities. Stroke with a focus on the elderly is a field where few studies have been conducted from a gender and socioeconomic perspective. With further community-based stroke incidence studies including elderly men and women and with the development of appropriately targeted interventions, the burden of stroke in the population could be reduced. More research is needed where both qualitative and quantitative methods are used, as this can provide a richer and perhaps more authentic description of the issue under investigation.

Full textAbstract:
The training and skills of educational psychologists (EPs) mean that they are uniquely qualified to deliver critical incident (CI) support to educational settings. One aspect of this support may involve producing written guidelines for schools; however such guidelines have received almost no attention in the research literature. An exploratory study was undertaken, in two phases, to explore current practice in the production and use of CI guidelines. Phase 1 involved the collection and content analysis of guidelines from a random sample of educational psychology services (EPSs) in England and Wales. Phase 2 involved semi-structured interviews with professionals, predominantly EPs; transcripts were analysed using thematic analysis. In phase 1, 97% of the sample stated that their EPS offered CI support to schools and 83% stated that they had produced written guidelines to support schools. Analysis found that the most frequently occurring content covered: how to initiate support (95%); recommended actions for CI preparation (68%) and CI response (95%); website addresses (68%) and booklists (50%); psycho-education about grief and trauma (64%) and examples of scripts and templates (55%). Recommendations and information were largely consistent with evidence in the academic literature. Interviewees described the benefits of written guidelines but maintained personal contact was an essential part of CI intervention. The role of guidelines, their limitations and implications for EP practice are discussed.

Mcknight, Peggy Ann. "Strategies Small Construction Business Managers Use to Reduce Safety Incidents in Their Organization." ScholarWorks, 2018. https://scholarworks.waldenu.edu/dissertations/5574.
Full textAbstract:
Globally the construction industry struggles to prevent injurious and fatal safety incidents. The purpose of this single case study was to explore strategies used by construction business managers that had significantly reduced the occurance of safety incidents in a Northwest Ohio construction company. Data were collected from organizational records and interviews with 6 construction managers. The conceptual framework for this research was the concept of safety management systems. Data were compiled and organized, disassembled into fragments, grouped, and then interpreted for meaning. Methodological triangulation and member checking were used to enhance reliability and validity. Four themes emerged from the data: senior management's commitment to a culture of safety, comprehensive safety training, safety accountability, and the importance of engaged employees. These findings indicate that senior managers established a safety-oriented culture by systematically implementing the safety management systems principles and practices in every organizational process and procedure. Safety training ensured that workers have the necessary skills to perform safely. All leaders, at every level of the organization, were held accountability for monitoring and measuring safety performance. Engaged workers were receptive to and compliant with safety rules. The positive social implications of these findings include the potential of contributing to the efforts to establish safer and healthier workplaces that protect workers from injuries and fatalities, thereby contributing to overall safety and health of communities.

Full textAbstract:
The identification of factors contributing to the farmers' non-retention of subsidy dollars is key in identifying the impact of the subsidy within and across the sector. Relaxing the assumption of perfect competition, amongst input suppliers, allows for an analysis of two upstream of complementary goods. Because it is the case that the farmers are price takers for some inputs (seed) and may negotiate over the price of others (land), I assume the upstream input providers are more akin to Bertrand competition. General findings, from the theoretical and experimental results, indicate upstream market power as having a significant impact on the economic subsidy incidence; and the complementary between the famer's inputs is the main driving force of the results.

Full textAbstract:
This thesis describes a case study which was designed to evaluate data derived from an analysis of a critical incident at Nene College of Higher Education. The purpose of the case study is to assess whether there is any evidence derived from the analysis of the data emanating from the critical incident to indicate (1) that some or all theoretical models of educational management existed in practice in a Higher Education Institution (HEI), and (2) that one or more theoretical models of educational management in that HEI may dominate in practice. In addition, the case study results are used to respond to research questions relating to organisational goals and culture as well as the influence of the external and internal environment upon the members of College staff involved in the critical incident. The results are also used to examine the likelihood of particular theoretical models of educational management being more or less dominant at different levels of the College's hierarchy and provides the evidence against which a new comprehensive model integrating five theoretical models of educational management can be evaluated. The thesis concludes that formal, collegial, ambiguity, political and cultural models were in evidence throughout the critical incident, although formal, collegial and cultural models tended to dominate across all organisational hierarchical levels. The external environment played a key contextual role in the process of the incident response, and the clarity of the organisation's goals and the positive subscription to those goals of staff interviewed was significant in overcoming the problems posed by the critical incident. In addition, the results indicated that the College's culture was a powerful factor in determining the manner in which the critical incident was handled. As a consequence, a new comprehensive model of educational management has been developed which included the cultural model as a variable.

Barr, Sue. "The architecture of transit : photographing incidents of sublimity in the landscapes of motorway architecture between the Alps and Naples." Thesis, Royal College of Art, 2017. http://researchonline.rca.ac.uk/2851/.
Full textAbstract:
The aesthetics of motorway architecture has not received attention within theoretical photographic discourse and has never been the subject of an academic photographic research project. This project begins from the understanding of the motorway as one continuous piece of architecture that crosses international boundaries on its route across Europe – an architecture so large that it cannot be perceived in its entirety. As a research-by-practice PhD, photography is used to identify and record incidents of the sublime in the route of the motorway. The photographs are produced with a large field study from the Swiss Alps to Naples, where numerous complex topographical and spatial conditions are found. This results in incidents of the sublime within its architecture when the motorway is forced to negotiate these conditions during its route. The research domain was chosen for its significance within the history of art and literature in European cultural history. Travelling in these regions was and is strongly related to the development of cultural concepts of the sublime. The questions that this research investigates are: Is it possible to make a depiction of architectural, spatial, topographical factors combined in a sublime incident? Can a methodology be defined to photograph these structures? How can photographs be made of large-scale architecture that cannot be seen or experienced in their entirety? The meaning of the term sublime has become diluted in contemporary usage, often being used inaccurately in description of something exquisite or delightful. This project revisits 18th-century formulations of this aesthetic categorisation, alongside historical travel literature, representations of landscape in painting and photography and contemporary architectural and photographic discourses. These references enable a thorough understanding of principles of aesthetic composition, resulting in the creation of a new understanding of the sublime and methodology for photographing large-scale motorway architecture. Employing a photographic aesthetic that embraces representation and post-production enhancement of Fine Art practice, the project culminates in the production of 29 photographs that form a narrative series exploring incidents of the sublime within motorway architecture between the Alps and Naples.

Full textAbstract:
L’œuvre d'Andy Warhol a été évaluée dans le contexte culturel du Pop Art en fonction de certains thèmes : condition de l'image médiatique, héritage duchampien, paradoxes du modernisme, statut de la marchandise, unicité de l’œuvre d'art... Ce faisant, la culture propre de Warhol, déterminée par son rapport à la religion chrétienne, a été largement ignorée. Ces essais interrogent l'articulation d'une culture et d'une pensée religieuses à une pratique et à des motifs modernes à partir d'un changement de paradigme et de perspective. Il fallait vérifier comment ces sources chrétiennes se manifestent dans le détail et en évaluer les conséquences sur l'interprétation. Les questions de l'incarnation et de l'individuation, telles qu'il les traite dans ses portraits, ne sont pas envisageables sans une réflexion sur son rapport à la religion chrétienne. Plus généralement, ce point de vue fait ressortir le rapport complexe de Warhol à la modernitéThe work of Andy Warhol has been evaluated in the context of Pop Art, and scholarship favored a number of themes: the condition of the mass media image, Marcel Duchamp's legacy, the paradoxes of modernism, the status of commodities, the notion of originality of the artwork... So that his specific culture, established in a stringent relationship to Christian religion, has regularly been largely ignored. This dissertation envisions the articulation of a religious culture and thinking to modern praxis and topics. Thus, a change of paradigm and perspective is required. It became necessary to substantiate how the Christian inspiration reveals itself in the work and modify its interpretation. The issues of incarnation and individuation, as Warhol handles them in his series of commissioned portraits, can't be understood without an extended examination of his relationship to Christian theology. More generally, this standpoint does stress Warhol's complex attitude towards modernism

A random search optimization method based off an analogous process for the slow cooling of metals is explored and used to find the optimum solution for a number of regression models that analyze nuclear, radiological, biological,and chemical terrorism targets. A non-parametric simulation based off of historical data is also explored. Simulated series of 30 years and a 30 year extrapolation of historical data are provided. The inclusion of independent variables used in the regression analysis is based off existing work in the reviewed literature. CBRN terrorism data is collected from both the
Monterey Institute's Weapons of Mass Destruction Terrorism Database as well as from the START Global Terrorism Database. Building similar models to those found in the literature and running them against CBRN terrorism incidence data determines if conventional terrorism indicator variables are also significant predictors of CBRN terrorism targets. The negative binomial model was determined to be the best regression model available for the data analysis. Two general types of models are developed, including an economic development model and a political risk model. From the economic development model we find that national GDP, GDP per capita, trade openness, and
democracy to significant indicators of CBRN terrorism targets. Additionally from the political risk model we find corrupt, stable, and democratic regimes more likely to
experience a CBRN event. We do not find language/religious fractionalization to be a significant predictive variable. Similarly we do not find ethnic tensions, involvement in external conflict, or a military government to have significant predictive value.

Lin, Yushun. "PARAMETRIC ESTIMATION IN COMPETING RISKS AND MULTI-STATE MODELS." UKnowledge, 2011. http://uknowledge.uky.edu/statistics_etds/1.
Full textAbstract:
The typical research of Alzheimer's disease includes a series of cognitive states. Multi-state models are often used to describe the history of disease evolvement. Competing risks models are a sub-category of multi-state models with one starting state and several absorbing states.
Analyses for competing risks data in medical papers frequently assume independent risks and evaluate covariate effects on these events by modeling distinct proportional hazards regression models for each event. Jeong and Fine (2007) proposed a parametric proportional sub-distribution hazard (SH) model for cumulative incidence functions (CIF) without assumptions about the dependence among the risks. We modified their model to assure that the sum of the underlying CIFs never exceeds one, by assuming a proportional SH model for dementia only in the Nun study. To accommodate left censored data, we computed non-parametric MLE of CIF based on Expectation-Maximization algorithm. Our proposed parametric model was applied to the Nun Study to investigate the effect of genetics and education on the occurrence of dementia. After including left censored dementia subjects, the incidence rate of dementia becomes larger than that of death for age < 90, education becomes significant factor for incidence of dementia and standard errors for estimates are smaller.
Multi-state Markov model is often used to analyze the evolution of cognitive states by assuming time independent transition intensities. We consider both constant and duration time dependent transition intensities in BRAiNS data, leading to a mixture of Markov and semi-Markov processes. The joint probability of observing a sequence of same state until transition in a semi-Markov process was expressed as a product of the overall transition probability and survival probability, which were simultaneously modeled. Such modeling leads to different interpretations in BRAiNS study, i.e., family history, APOE4, and sex by head injury interaction are significant factors for transition intensities in traditional Markov model. While in our semi-Markov model, these factors are significant in predicting the overall transition probabilities, but none of these factors are significant for duration time distribution.

Full textAbstract:
S’appuyant sur les théories du financement hiérarchique et du compromis, cette recherche se donne pour objectif de tester empiriquement la relation structure financière-institution. Ces deux notions partagent des caractéristiques communes favorisant leur association conceptuelle à travers le ratio d’endettement cible spécifiquement via le comportement de conservatisme financier des entreprises. Cela ouvre de nouvelles possibilités d’analyses de ladite relation, notamment, en mobilisant le néo-institutionnalisme. Un échantillon de 204 entreprises françaises cotées à la bourse de Paris, ayant des données complètes entre 1999 et 2007, a servi à entreprendre le volet empirique de l’étude. Les principaux résultats indiquent que l’ensemble des déterminants traditionnels de la structure financière, à l’exception de la taille, joue un rôle important dans la politique de financement de ces entreprises. Le niveau de corruption et la liquidité du marché boursier français (variables institutionnelles juridico-financières) n’influencent pas le choix du niveau d’endettement, mais jouent plutôt un rôle significatif dans le choix de la maturité de la dette. Par ailleurs, la structure financière de ces entreprises converge lentement mais sûrement vers son niveau cibleBased on the pecking order and trade-off theories, this research aims to test empirically the relationship between corporate capital structure and institution. Both concepts share common characteristics fostering their conceptual association through the target debt ratio specifically via corporate behavior of financial conservatism. This opens new possibilities for analysis of that relationship, in particular, by mobilizing the new institutionalism framework. A sample of 204 French companies listed on the Paris stock exchange, with complete data between 1999 and 2007, was used to undertake the empirical part of the study. The main results indicate that all the traditional determinants of capital structure, except the size, play an important role in the financing policy of these companies. The level of corruption and the French stock market liquidity (legal and financial institutional variables) do not influence the choice of debt level, but rather play a significant role in the choice of debt maturity. In addition, the financial structure of these companies converges slowly but surely toward its target level

Full textAbstract:
Europe is currently in a stage of increased military spending due to greater insecurity in the region. Previous studies claim that one consequence of such an increase may be greater reliance on the military in matters that had previously been handled by civil agencies. Are societies in Europe facing a change in which the military will be more involved in crisis incident response? The purpose of this study is to examine if the role of the military in a society depends on the level of militarization of the country. With the foundational question of why the military has different roles within different societies, this study focuses on civil-military cooperation (CIMIC) dealing with CBRN (Chemical, Biological, Radioactive and Nuclear)-related issues, in order to investigate the possible relationship between CIMIC and militarization. Empirical data from countries with high- and low levels of militarization are collected, and thereafter analyzed and categorized into “ideal types” of CIMIC. The forms of each country are then compared and put in the context of militarization in order to answer the foundational question. This study initiates the closing of a research gap regarding examination and analysis of the relationship between militarization and CIMIC during CBRN incident response. Additionally, this study marks the initial development of a method, including new “ideal types”, that enables the comparison of CIMIC, opening new doors for analysis of civil-military cooperation.

Anderson, Desiree. "The Use of Campus Based Restorative Justice Practices to Address Incidents of Bias: Facilitators’ Experiences." ScholarWorks@UNO, 2018. https://scholarworks.uno.edu/td/2442.
Full textAbstract:
Student conduct plays an integral role in the functioning of an institution and the moral development of students. As multiple models of student conduct exist, such as the Model Student Conduct Code or a Restorative Justice Approach, it is critical to have an understanding of the various structures and how to choose the most effective structure for addressing the diversifying needs of the campus community. Most college and university campuses use the Model Student Conduct Code (Dannells, 1997) which tends to place a heavy emphasis on authority and is more legalistic which creates an “adversarial environment” (Lowery & Dannells, 2004) on college and university campuses. It can be argued that the traditional student conduct code does not make space for individuals to engage in dialogue and for learning to take place. The focus of this dissertation is to understand the experiences of facilitators as they develop, implement, and use restorative justice models on college and university campuses, which provide a guiding framework for dialogue between victims/harmed parties and offenders/respondents and may be better suited as a means of managing bias and hate-motivated incidents. Restorative practices have been implemented in criminal justice, and K-12 environments and are seen by some as an antidote to overly legalistic campus conduct processes (Karp, 2004). This phenomenological research explores the experiences of individuals who have facilitated a campus-based restorative process and how that experience may impact their view of and the opportunities to improve campus climate through the lens of Critical Race Theory and Models of Moral development. Through this study, conduct and other campus administrators can gain valuable information on how restorative processes are developed, how facilitators gained and maintained institutional support, and how successful facilitators find the process in meeting their goals of student learning. Campus administrators will also gain insight on the perceived effectiveness of restorative practices as a tool for managing incidents of bias and the perception of the campus climate.

Full textAbstract:
The reported number of hate crimes in New Jersey continues to remain high despite the enforcement of laws against perpetrators. The purpose of this correlational panel study was to test Shaw & McKay's theory of social disorganization by examining the relationship between demographic diversity and hate crime rates. This study focused on analyzing the relationship between the level of diversity, residential mobility, unemployment, family disruption, proximity to urban areas, and population density in all 21 New Jersey counties and hate crime rates. The existing data of Federal Bureau of Investigations' hate crime rates and the U.S. Census Bureau's demographic diversity, operationalized as the percentage of Whites over all other races, and social disorganization from 21 between the years 2007 through 2011, for a total sample size of 105 cases of reported hate crimes. Results of the multiple linear regression analysis indicate that ethnic diversity did not significantly predict hate crimes (p = 0.81), residential mobility (p < 0.001), and population density (p < 0.001) had positive effects on hate crime rates. Concentrated disadvantage (p = 0.01), characterized by the number of reported unemployment rates, had a negative effect on hate crime rates. The results of the study supported social disorganization theory in reference to residential mobility and population density. Law enforcement agencies can use the results of this study to combat hate crimes in areas with a high level of residential mobility and population density.

Full textAbstract:
The threat and occurrence of terrorist attacks have increased in the United States since September 2011, heightening concerns for weaponized anthrax, other biological pathogens, and epidemics and pandemics. Early decisions and funding levels in local public health agencies can be the first line of defense or first point of failure; yet little is understood about how decisions are made when there are budget cuts before a biological event happens. Using Lindblom's conceptualization of limited rational choice theory, the purpose of this single case study was to understand how a local public health official made decisions after budget cuts in a single public health entity in the mid-Atlantic area of the United States. Data were collected through an interview with 1 public health official and publicly available plans, procedures, and funding documents. These data were inductively coded and then subjected to Braun and Clarke's thematic analysis procedure. Findings indicated that the public health agency's ability to make the best decisions were negatively impacted by limited resources, though adequate planning before a catastrophic event, active and continual communication with stakeholders, and clarity about financial and resource needs can partially offset the impact of budgetary reductions. The implications for social change include recommendations to anticipate and address the needs of the public health system through decision making to protect the health care community and the reduction or elimination of the spread of disease in the wake of a biological incident.

Full textAbstract:
Notre thèse s’intéresse à la restructuration du service social d’une plate-forme téléphonique de santé – Santé Info. Au moment de l’étude le service social de ce centre de contact venait de faire l’objet d’une importante réorganisation, qui s’est concrétisée par la création d’une équipe de télé-opérateurs spécialisés. Dans ce contexte de changement organisationnel, notre travail vise à comprendre les incidences du développement de l’activité sur les pratiques situées des acteurs et saisir comment celles-ci nourrissent ce développement en retour. Nos réflexions autour de cette question sont inspirées par les théories de l’activité ainsi que les courants de la cognition et de l’action située. Nous nous appuyons sur la notion de perspective professionnelle et proposons la notion de saillance afin de rendre compte du développement de l’activité en pratique. Nous avons conduit une enquête ethnographique de près de deux ans au sein de cette organisation. Le dispositif méthodologique que nous avons mis en œuvre privilégie l’observation in situ des pratiques. La stratégie observationnelle choisie était celle du suivi, celui i) des acteurs, ii) des affaires c’est-à-dire des demandes traitées par plusieurs intervenants et iii) des situations de communication collective (formations, réunions d’équipe). Nous avons par ailleurs mobilisé la méthode de l’autoconfrontation à partir d’enregistrements audiovisuels. Nos résultats mettent en évidence deux axes de développement contradictoires de l’organisation, à savoir, d’une part, une tendance à l’intégration aux services des mutuelles fondatrices et une tendance à l’autonomisation de Santé Info en tant que prestataire de service externe. D’autre part, la restructuration du service social peut être appréhendée comme actualisant une contradiction sous-jacente au système d’activité, celle entre travail d’information (informer) et conseil (conseiller). Nous analysons les pratiques de prise et de construction de configurations d’indices informationnels des professionnels que nous qualifions de saillances. Nos analyses mettent en évidence que connaître son travail revient à connaître le travail des autres c’est-à-dire à anticiper leurs contraintes, leurs éventuelles difficultés, à reconnaître et tenir compte des impératifs auxquels ils doivent faire face (temporels et de production). La restructuration du service social de Santé Info au travers de la création d’une équipe spécialisée de téléconseillers – le pôle social - contribue à transformer ces pratiques. Par ailleurs, les nouvelles exigences que cette restructuration fait peser sur les professionnels participent de la redéfinition des enjeux de leurs actions en situation. En d’autres termes connaître le travail d’autrui est une ressource pour le collectif mais aussi pour le sujet. Les contributions de ce travail de thèse se situe à trois niveaux : théorique, méthodologique et disciplinaire. L’apport théorique réside dans la recherche d’une articulation entre une analyse orientée par les théories de l’activité et les approches situées de la cognition et de l’action. Ces questions nourrissent des enjeux méthodologiques pour notre travail, qui constituent le second apport de notre recherche. Il s’agit également de construire un dispositif d’observation et de collecte systématique de données dans un environnement professionnel exigeant où le travail est, à la fois, intellectuel et relationnel, la coopération latente et différée, et qui s’étayent sur une infrastructure sociotechnique complexe. Du point de vue de la psychologie du travail, notre étude ouvre à une réflexion autour des compétences collectives et du bien-être au travailOur research deals with the organizational change within Health Info, the inbound call center for a number of mutual health insurance companies. Health Info provides users with health information and referral for the purpose of helping them to make better choices in healthcare and to reduce their expenses. In order to improve the service delivered to the clients of the mutual insurance companies, call operators’ activity was redesigned. Some of the most experienced call center agents formed a new team (referred as the « social team »), which had the responsibility to process the information requests of users in need of financial support, different kind of allowances, within outbound calls. In this context, the goals of this doctoral thesis is to understand this organizational change as a development, that of Health Info’ collective activity but also that of the local individual practices. We build upon three approaches to the study of context - activity theory, situated action and situated cognition. Our research is based on a two years ethnographic study. We have used various data collection techniques. Those included ethnographic observation, video recordings of naturally occurring situations as well as interviews with staff members. We systematically attended and video recorded the regular staff meeting of the « social team ». We also shadowed staff members and followed specific « client cases » as first identified by call operators, then processed by the members of the « social team » and eventually transferred for further analysis to the social worker. Our results highlight several contradictions underlying Health Info’ current development. On one hand, Health Info is an additional service designed to fit within the those already existing of the mutual insurance companies. But it is also an autonomous service provider whose clients are the mutual companies. On the other hand, the « social team » reveals another contradiction between different work perspectives, namely that of informing users and helping them or providing them with support. Furthermore, our study underlines the practical dimensions of Health Info’ restructuring. The analysis of situated practices shows that works perspectives are grounded on salient configurations which are both emergent in situ and collectively elaborated cultural resources. The contributions of this doctoral thesis are to address some of the a) methodological and b) conceptual challenges arising from the use of activity theory as a theoretical framework in empirical studies, c) triggers off some interesting considerations on collective competencies and on well-being in the workplace

Full textAbstract:
A significant amount of research in the field of small business management has correlated small firm performance with the sophistication of overall management skills (see, for example, Gasse, 1997; Gadenne, 1998; Zinger, leBrasseur and Zannibi, 2001; Balderson, 2003) and more particularly problem solving skills. Yet, even though problem solving skills are at the core of the small business management process (Jennings and Beaver, 1997), there has been little research to date that has focused on understanding the actual approach small business owner-managers take to solve the problems they encounter as the present study has done, through the utilization of an interpretive research design applied to a sample of small firms. The primary purpose of this exploratory study is to investigate the nature of problem solving practices adopted by 11 small business owner-managers on Central Vancouver Island, Canada, by identifying the types of problems encountered in the years following their establishment, the actions taken to solve these problems and the outcomes of these actions for the firm. It examines the characteristics of the problemm solving approaches utilized by owner-managers as they encountered problems, and identifies how they perceived the impact of the approach taken on the continued survival of their firm. The methodological approach taken in this study is positioned within an emergent body of research in the field of small business and entrepreneurship that applies an interpretive paradigm to uncover the complex facets of how individuals develop their capabilities and management practices (Chell and Allman, 2003) with a particular emphasis on the small business owner-manager. The interpretive assumptions guiding the research process have allowed new understandings to emerge about problem solving in small firms within the wider context of managerial capability as a critical contributor to small business survival. More specifically, the critical incident technique method (Flanagan, 1954; Chell, 1998), along with an approach to data analysis and coding that draws from grounded theory (Glaser, 1992; Glaser and Strauss, 1999; Strauss and Corbin, 1998), are combined and applied as a qualitative research strategy. This strategy has not previously been used in relation to the study of problem solving in small firms. This interpretive paradigm allows the exploration of how small business owner-managers attach meaning to their subjective experiences and the implications of these perceptions for the business outcomes of the firm, specifically as they relate to solving critical business problems. As a result, the interpretive methods applied in the course of this study make a novel contribution to the field, since they have yielded new interpretations on the nature of problem solving processes in the sample of small firms studied. The findings presented here reveal the intuitive, improvised and non-linear nature of how problems are actually solved in these small firms, in contrast to a number of well-known theoretical research frameworks that propose well-defined and delineated steps in the problem solving process. The results of this study make a valuable contribution to building new theory in this area of inquiry by demonstrating how more dynamic processes occur in practice. An alternative way to conceptualize problem solving in small firms is presented in Chapter 6, A Holistic Framework for Problem Solving in Small Firms.

La presente tesis estudia la relación entre los factores institucionales (formales e informales) y la transparencia sobre gobierno corporativo en las empresas de mayor cotización bursátil en los países emergentes latinoamericanos. Adoptando los enfoques de la teoría institucional y la teoría de la agencia, el objetivo ha sido identificar aquellas variables institucionales a nivel macro y a nivel empresa que tienen una influencia significativa sobre el nivel de transparencia en gobierno corporativo, medido a través de la construcción de un índice de divulgación que cubre el período 2004-2010.
Así, nuestra muestra de estudio se integra de 826 observaciones que pertenecen a los índices de mayor cotización bursátil de las bolsas de valores en Argentina (MERVAL), Brasil (IBOVESPA), Chile (IPSA) y México (IPyC). La aportación principal de la investigación es la propuesta de un modelo empírico que refleja la relación de un conjunto de factores institucionales y el nivel de transparencia en gobierno corporativo en el contexto de los países emergentes latinoamericanos, donde la investigación previa es escasa.
Los resultados sugieren que los factores institucionales, formales e informales, y algunas de las variables de control tienen un poder explicativo en el nivel de transparencia en gobierno corporativo de las empresas cotizadas en estos países. El estudio identifica el estado actual de la convergencia regional en las prácticas de buen gobierno en los países emergentes latinoamericanos, pudiendo ser un punto de referencia para los responsables de emitir las políticas y directrices sobre gobierno corporativo.

Full textAbstract:
Research related to the school counselor's journey to social justice advocacy is minimal. An exploration of the school counselor's journey to social justice advocacy and the impact it has on the counselor's work with students is needed. Furthermore, research related to the needs and challenges of undocumented students have not been explored.
The purpose of this study was to explore the social justice identity development of professional school counselors who identify as advocates for undocumented students through critical incidents. The study is grounded in Bobbie Harro's Cycle of Liberation and Relational Cultural Theory to answer the following research questions: (1) What do school counselors who identify as social justice advocates describe as critical incidents in their social justice identity development when working with undocumented students? (2) How have these critical incidents impacted the social justice identity development of professional school counselors? I enlisted a qualitative approach utilizing the Critical Incident Technique (Flanagan, 1954) to address the research questions.
Six secondary school counselors participated in this study. Five were female, two were white, two were Hispanic, one was African-American, and one was bi-racial. Four were citizens, one was a naturalized citizen and one was a DACA recipient. One had been a school counselor for 1 - 3 years, two for 3-5 years, and 3 had been school counselors for more than 7 years. The critical incidents identified by the participants related to personal experiences such as parental influence, family experiences, and influence of educators; formal learning such as experiential learning and academic learning; past work experiences; and student impact on the counselor.
The school counselor's relationship with an undocumented student or immigrant played a role in the participants social justice identity development. The school counselors' identity development mirrored Harro's (2000) Cycle of Liberation. As a result of the critical incidents provided by the participants, connection and introspection emerged. The connection and introspection liberated the counselor and served as the process towards the counselors' social justice identity development.Ph. D.

Full textAbstract:
The misuse of alcohol is well documented in Australia and has been associated with disorders and harms that often require police attention. The extent of alcohol-related incidents requiring police attention has been recorded as substantial in some Australian cities (Arro, Crook, & Fenton, 1992; Davey & French, 1995; Ireland & Thommeny, 1993). A significant proportion of harmful drinking occurs in and around licensed premises (Jochelson, 1997; Stockwell, Masters, Phillips, Daly, Gahegan, Midford, & Philp, 1998; Borges, Cherpitel, & Rosovsky, 1998) and most of these incidents are not reported to police (Bryant & Williams, 2000; Lister, Hobbs, Hall, & Winlow, 2000). Alcohol-related incidents have also been found to be concentrated in certain places at certain times (Jochelson, 1997) and therefore manipulating the context in which these incidents occur may provide a means to prevent and reduce the harm associated with alcohol misuse.
One of the major objectives of the present program of research was to investigate the occurrence and resource impact of alcohol-related incidents on operational (general duties) policing across a large geographical area. A second objective of the thesis was to examine the characteristics and temporal/spatial dynamics of police attended alcohol incidents in the context of Place Based theories of crime. It was envisaged that this approach would reveal the patterns of the most prevalent offences and demonstrate the relevance of Place Based theories of crime to understanding these patterns. In addition, the role of alcohol, time and place were also explored in order to examine the association between non criminal traffic offences and other types of criminal offences. A final objective of the thesis was to examine the impact of a situational crime prevention strategy that had been initiated to reduce the violence and disorder associated with late-night liquor trading premises.
The program of research in this doctorate thesis has been undertaken through the presentation of published papers. The research was conducted in three stages which produced six manuscripts, five of which were submitted to peer reviewed journals and one that was published in a peer reviewed conference proceedings. Stage One included two studies (Studies 1 & 2) both of which involved a cross sectional approach to examine the prevalence and characteristics of alcohol-related incidents requiring police attendance across three large geographical areas that included metropolitan cities, provincial regions and rural areas. Stage Two of the program of research also comprised two cross sectional quantitative studies (Studies 3 & 4) that investigated the temporal and spatial dynamics of the major offence categories attended by operational police in a specific Police District (Gold Coast). Stage Three of the program of research involved two studies (Studies 5 & 6) that assessed the effectiveness of a situational crime prevention strategy. The studies employed a pre-post design to assess the impact on crime, disorder and violence by preventing patrons from entering late-night liquor trading premises between 3 a.m. and 5 a.m. (lockout policy). Although Study Five was solely quantitative in nature, Study Six included both quantitative and qualitative aspects. The approach adopted in Study Six, therefore facilitated not only a quantative comparison of the impact of the lockout policy on different policing areas, but also enabled the processes related to the implementation of the lockout policy to be examined.
The thesis reports a program of research involving a common data collection method which then involved a series of studies being conducted to explore different aspects of the data. The data was collected from three sources. Firstly a pilot phase was undertaken to provide participants with training. Secondly a main study period was undertaken immediately following the pilot phase. The first and second sources of data were collected between 29th March 2004 and 2nd May 2004. Thirdly, additional data was collected between the 1st April 2005 and 31st May 2005.
Participants in the current program of research were first response operational police officers who completed a modified activity log over a 9 week period (4 week pilot phase & 5 week survey study phase), identifying the type, prevalence and characteristics of alcohol-related incidents that were attended. During the study period police officers attended 31,090 alcohol-related incidents. Studies One and Two revealed that a substantial proportion of current police work involves attendance at alcohol-related incidents (i.e., 25% largely involving young males aged between 17 and 24 years). The most common incidents police attended were vehicle and/or traffic matters, disturbances and offences against property. The major category of offences most likely to involve alcohol included vehicle/traffic matters, disturbances and offences against the person (e.g., common & serious assaults). These events were most likely to occur in the late evenings and early hours of the morning on the weekends, and importantly, usually took longer for police to complete than non alcohol-related incidents.
The findings in Studies Three and Four suggest that serious traffic offences, disturbances and offences against the person share similar characteristics and occur in concentrated places at similar times. In addition, it was found that time, place and incident type all have an influence on whether an incident attended by a police officer is alcohol-related. Alcohol-related incidents are more likely to occur in particular locations in the late evenings and early mornings on the weekends. In particular, there was a strong association between the occurrence of alcohol-related disturbances and alcohol-related serious traffic offences in regards to place and time. In general, stealing and property offences were not alcohol-related and occurred in daylight hours during weekdays.
The results of Studies Five and Six were mixed. A number of alcohol-related offences requiring police attention were significantly reduced for some policing areas and for some types of offences following the implementation of the lockout policy. However, in some locations the lockout policy appeared to have a negative or minimal impact. Interviews with licensees revealed that although all were initially opposed to the lockout policy as they believed it would have a negative impact on business, most perceived some benefits from its introduction. Some of the benefits included, improved patron safety and the development of better business strategies to increase patron numbers.
In conclusion, the overall findings of the six studies highlight the pervasive nature of alcohol across a range of criminal incidents, demonstrating the tremendous impact alcohol-related incidents have on police. The findings also demonstrate the importance of time and place in predicting the occurrence of alcohol-related offences. Although this program of research did not set out to test Place Based theories of crime, these theories were used to inform the interpretation of findings. The findings in the current research program provide evidence for the relevance of Place Based theories of crime to understanding the factors contributing to violence and disorder, and designing relevant crime prevention strategies. For instance, the results in Studies Five and Six provide supportive evidence that this novel lockout initiative can be beneficial for public safety by reducing some types of offences in particular areas in and around late-night liquor trading premises. Finally, intelligent-led policing initiatives based on problem oriented policing, such as the lockout policy examined in this thesis, have potential as a major crime prevention technique to reduce specific types of alcohol-related offences.

Full textAbstract:
The need for increasing efficiencies for medical resource delivery during a mass casualty incident/event is a paramount logistical planning factor that could mean life or death to the citizens affected by a disaster. As such, Washington State has prioritized emergency management and preparedness. Using the just-in-time system by way of Baghbanian' s complex adaptive decision-making theory as the foundation, gave purpose to this qualitative study. This was accomplished by analysis of emergency management professional responses, and to what degree, improvements can be made to the medical resource delivery system during a mass casualty incident/event. Data were collected through semi structured interviews with a random sample of 12 experienced emergency professionals from the State of Washington. This study was guided by primary research questions that focused on emergency managers and their understanding and adaptability toward preparedness. Interview data were deductively coded and analyzed through a thematic analysis procedure. The key theme of this study is that participants perceived slight differences in logistical and operational approaches that vector into transportation and operational understanding as the main factors influencing medical resource delivery. The positive social change association of this study is that it provides emergency managers, first responders, and medical staff with recommendations for analysis and planning development for medical resource delivery, thereby mitigating the life and death implications for citizens in future disasters.

Full textAbstract:
Ce travail de didactique des mathématiques s'appuie sur le cadre de la Théorie des Situations Didactiques et s'intéresse à l'action conjointe des professeurs et des élèves dans un environnement numérique et à la dynamique que cette action conjointe engage. Il s'appuie aussi sur le cadre théorique de l'approche documentaire, qui complète et prolonge le cadre de l'approche instrumentale : les artefacts numériques présents dans cet environnement sont ainsi considérés comme des éléments du système documentaire des professeurs et des élèves. Considérant l'intégration de ces artefacts dans la classe ordinaire de mathématiques, nous mettons en évidence l'importance de moments particuliers, que nous nommons incidents didactiques, qui engagent des perturbations modifiant la dynamique de la classe. En développant cette notion d'incident didactique, nous construisons un cadre d'analyse permettant de mettre en évidence des phénomènes de genèse documentaire des enseignants et des élèves et d'en suivre les effets, à court ou à long terme, sur l'enseignement et l'apprentissage des mathématiques. Nous montrons que les incidents didactiques peuvent être, sous certaines conditions, des occasions de réorganisation locale et globale des connaissances pour le professeur dans le cadre de son enseignement ou pour l'élève dans son apprentissage des mathématiques
