Full textAbstract:
The sensitivity of electromagnetic force compensated weighing cells can be enhanced by adjusting the relative distance between two specific joints in its mechanism. However, owing to the difficulties of the adjustment of the flexure hinge position in the compliant mechanism, this adjustment option has not yet been realized. In this scientific thesis, an adjustment device was developed. This adjustment device can be integrated into an EMFC weighing cell and allows adjustments while the balance is in operation. To this end, the guideline VDI 2221 was applied in the design process to develop possible concept solutions.
The most suitable option was selected by a technical-economic analysis. The technical realization of the selected solution concept was elaborated based on design guidelines and model equations. The adjustment device was designed to work under a tensile force of up to 15 N. A finite element analysis was performed to evaluate the operation of the adjustment device. This analysis demonstrates the feasibility of the device to shift the flexure hinge within a displacement range of 6 mm. The numerical analysis reveals an angular deflection up to 7.2 arcsec perpendicular to the rotational axis of the adjusted joint. Based on the original model, geometry variations of certain components were investigated to identify optimization possibilities. It was found that the angular distortion can be diminished by a more symmetric setup, especially concerning the linear guide.Die Empfindlichkeit von elektromagnetisch kraftkompensierten Wägezellen kann durch die Justierung des relativen abstands zwischen zwei spezifischen Festkörpergelenken erhöht werden. Aufgrund der Schwierigkeiten bei der Justierung der Festkörpergelenkposition im nachgiebigen Mechanismus ist diese Justiermöglichkeit jedoch noch nicht realisiert. In dieser Masterarbeit wurde ein eine Justiereinrichtung entwickelt. Diese Justiereinrichtung kann in eine EMFC-Wägezelle integriert werden und ermöglicht eine Justierung während des Betriebs der Waage. Zu diesem Zweck wurde im Entwicklungsprozess die Richtlinie VDI 2221 angewendet, um mögliche Konzeptlösungen zu entwickeln. Die geeignetste Option wurde durch eine technisch-ökonomische Analyse ausgewählt. Die technische Realisierung des ausgewählten Lösungskonzepts wurde auf der Grundlage von Designrichtlinien und Modellgleichungen erarbeitet. Die Justiereinrichtung wurde so konzipiert, dass sie unter einer Zugkraft von bis zu 15 N arbeitet. Eine Finite-Elemente-Analyse wurde durchgeführt, um den Funktion der Justiereinrichtung zu bewerten. Diese Analyse demonstriert die Möglichkeit des Gerätes, das Festkörpergelenk in einen Verschiebungsbereich von 6 mm zu verschieben. Die numerische Analyse zeigt eine Winkelauslenkung bis 7.2 arcsec senkrecht zur Drehachse des justierten Gelenks. Basierend auf dem Originalmodell wurden Geometrievariationen bestimmter Komponenten untersucht, um Optimierungsmöglichkeiten zu identifizieren. Es wurde festgestellt, dass die Winkelverzerrung durch einen symmetrischeren Aufbau, insbesondere hinsichtlich der Linearführung, verringert werden kann.

Full textAbstract:
The GIS Industry has digitised cadastre from the best available paper maps over the last few decades, incorporating the inherent errors in those paper maps and in the digitising process. The advent of Global Positioning Systems, modern surveying instruments and advances in the computing industry has made it desirable and affordable to upgrade the placement, in terms of absolute and relative position) of these digital cadastres. The Utility Industry has used GIS software to place their assets relative to these digital cadastres, and are now finding their assets placed incorrectly when viewed against these upgraded digital cadastres. This thesis examines the processes developed in the software program called the ???Spatial Adjustment Engine???, and documents a holistic approach to semi-automating the upgrading of the digital cadastre and the subsequent upgrading of the utility assets. This thesis also documents the various pilot projects undertaken during the development of the Spatial Adjustment Engine, the topological scenarios found in each pilot, their solution, and provides a framework of definitions needed to explore this field further. The results of each pilot project are given in context, and lead to the conclusions. The conclusions indicate the processes and procedures implemented in the Spatial Adjustment Engine are a suitable mechanism for the upgrade of digital cadastre and of spatially dependant themes such as utility assets, zoning themes, annotation layers, and some road centreline themes.

Full textAbstract:
Background: The latest generation of rear-end whiplash protection systems, as found in the WHIPS Volvo and SAHR Saab, have reduced injury rates by almost 50% in comparison with the previous generation of seat/head restraint systems. Occupant behaviour, such as seated posture and seat adjustment settings, may affect the injury risk. Method: Five studies were conducted. Studie I was an injury outcome study based on insurance data. Studies II-IV investigated seat adjustment, occupant backset, and cervical retraction for drivers and occupants in different postures and positions in the car, during stationary and driving conditions. Study V compared the occupant data from studies II and III with a vehicle testing tool, the BioRID dummy, using the protocols of the ISO, RCAR, and the RCAR-IIWPG. Results: Female drivers and passengers had a threefold increased risk for medically-impairing neck injury in rear-end impacts, compared to males. Driver position had a double risk compared with front passenger seat position. Female drivers adjusted the driver seat differently to male drivers; they sat higher and closer to the steering wheel and with more upright back support. The volunteers also adjusted their seat differently to the ISO, RCAR, and RCAR-IIWPG protocol settings; both sexes sat further away from the steering wheel, and seat back angle was more upright then in the protocols. In stationary cars, backset was highest in the rear seat position and lowest in the front passenger seat position. Males had a larger backset than females. Cervical retraction decreased and backset increased for both sexes when posture changed from self-selected posture to a slouched posture. The BioRID II dummy was found to represent 96th percentile female in stature, and a 69th percentile female in weight in the volunteer group. Conclusions: Risks in car rear-end impacts differ by sex and seated position. This thesis indicates the need for a 50th percentile female BioRID dummy and re-evaluation of the ISO, RCAR, and RCAR-IIWPG protocols, and further development of new safety systems to protect occupants in rear-end impacts.

Full textAbstract:
Today, 3D models of cities are created from aerial images using a camera rig. Images, together with sensor data from the flights, are stored for further processing when building 3D models. However, there is a market demand for a more mobile solution of satisfactory quality. If the camera position can be calculated for each image, there is an existing algorithm available for the creation of 3D models. This master thesis project aims to investigate whether the iPhone 4 offers good enough image and sensor data quality from which 3D models can be created. Calculations on movements and rotations from sensor data forms the foundation of the image processing, and should refine the camera position estimations. The 3D models are built only from image processing since sensor data cannot be used due to poor data accuracy. Because of that, the scaling of the 3D models are unknown and a measurement is needed on the real objects to make scaling possible. Compared to a test algorithm that calculates 3D models from only images, already available at the SBD’s system, the quality of the 3D model in this master thesis project is almost the same or, in some respects, even better when compared with the human eye.

Levi, Loïc. "Comportements d'investissement et performances des exploitations agricoles selon la position dans le cycle de vie." Thesis, Rennes, Agrocampus Ouest, 2018. http://www.theses.fr/2018NSARE053/document.
Full textAbstract:
L'investissement et l'innovation jouent un rôle important dans le secteur agricole, permettant aux exploitations de s'adapter aux changements de politiques et aux conditions du marché. Au cours des dernières décennies, les exploitations agricoles de l'Union européenne (UE) ont été confrontées à des changements substantiels à travers la politique agricole commune (PAC). C'est notamment le cas du secteur laitier, qui a vu la fin du régime de quotas laitiers et également vu une volatilité accrue des prix. De tels changements pourraient affecter la productivité et l’efficacité des exploitations agricoles, la compétitivité du secteur laitier et les changements structurels. Comprendre les mécanismes sous-jacents au comportement d’investissement des exploitations pourrait permettre d’identifier les principaux facteurs qui influent sur les tendances observées. Cela pourrait aider à anticiper les futurs changements structurels, prévoir les besoins des exploitations et aider les décideurs publicet les autres acteurs du secteur agricole à adapter leurs politiques. La thèse contribue à cet objectif en analysant pour les exploitations laitières d'une sous-région de Bretagne (Ille-et-Vilaine) en France, (i) l'impact de la suppression du quota laitier sur les décisions d'investissement des agriculteurs et l'hétérogénéité de leurs réactions (ii) le lien entre la performance agricole et les décisions d'investissement des agriculteurs, (iii) le rôle des interactions sociales liées aux effets de voisinage sur la décision d'investissement des agriculteurs. Les résultats montrent que la fin: Investment and innovation play an important role in the agricultural sector, allowing farms to adapt to policy changes and market condition changes. In the last decades, farms in the European Union (EU) have faced substantial changes in the Common Agricultural Policy (CAP). This is particularly the case of the dairy sector, which has seen the end of milk quota regime and increased price volatility. Such changes could affect farm productivity and efficiency, the dairy sector’s competitiveness and structural change. Understanding the mechanisms underlying farms’ investment behaviour could allow identifying key drivers that influence the observed trends. This could help anticipate future structural changes, predict farms’ needs and help policy makers and other stakeholders in farming to adapt their policy. The thesis contributes to this objective by analysing for dairy farms in a sub-region of Brittany (Ille-et-Vilaine) in France, (i) the impact of the termination of the milk quota onfarmers’ investment decisions and the heterogeneity of farm investment behaviour, (ii) the link between farm performance and farmers’ investment decisions, (iii) the role of social interactions related to neighbourhood effects on farmers' investment decision. Findings show that the termination of the dairy quota policy increased farmers’ incentive to invest, contributing to the trend towards larger, more capital intensive and more specialised dairy farms. In addition, the thesis underlines the need to take into account farmers’ heterogeneity in modelling investment behaviour. Doing so allows

Full textAbstract:
Thesis (MScPhysio)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Aims: To assess the effect of a vertical height adjustment of the chair and visual display unit (VDU) on work related upper quadrant musculoskeletal pain (WRUQMP) and sitting comfort in computer users. The upper quadrant refers to the occiput, cervical and upper thoracic spine including the clavicles and scapulae. Methods: An N=1 study was conducted using the ABC design whereby an ergonomic workstation adjustment, of VDU and chair height, was compared to the subject’s usual workstation settings. Pain and sitting comfort were measured using visual analogue scales (VAS). The subject was assessed over the four week phases as she performed her typical VDU work. The results were compiled and tabulated. Results: Both the mean and variance in pain intensity decreased after the workstation intervention. A deterioration was noted in sitting comfort. Conclusion: The vertical height adjustment of the chair and VDU may have contributed to a decrease in WRUQMP in this subject. This safe, economical workstation intervention may be a practical management option for the computer user suffering from WRUQMP. Further research into the measurement of comfort whilst sitting at a computer workstation, is recommended.
AFRIKAANSE OPSOMMING: Doelwitte: Om die effek te bepaal van n vertikale aanpassing van die stoel en beeldskerm van rekenaargebruikers op werksverwandte boonste kwadrant muskuloskeletale pyn en sitgemak. Die boonste kwadrant verwys na die oksiput, servikale en boonste torakale werwelkolom en sluit ook die klavikel en skapula in. Methode: Die N=1 studie is onderneem met gebruik van die ABC ontwerp in terme waarvan n ergonomiese aanpassing van stoel en beeldskerm vergelyk is met die normale gebruik van die deelnemer. Pyn en sitgemak is gemeet deur die gebruik van die Visueel analoogskaal. Die interwensies is ge-evalueer oor vierweekfases tydens normale rekenaar gebruik van die deelnemer. Die resultate is saamgestel en getabuleer. Uitkoms: Beide die gemiddelde en veranderlike pynintensiteit het verminder nadat die werkstasie aangepas is. Geen verbetering in sitgemak is opgemerk nie. Gevolgtrekking: Die vertikale hoogte-aanpassing van die stoel en beeldskerm het moontlik bygedra tot die verminderde pynvlakke in hierdie deelnemer. Hierdie veilige, ekonomiese verstelling is moontlik n praktiese beheeropsie vir rekenaargebruikers wat werksverwandte boonste kwadrant muskuloskeletale pyn verduur. Verder studie in die meet en waarneming van sitgemak tydens rekenaarwerk is nodig.

Thesis (MScPhysio)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Aims: To assess the effect of a chair and computer screen height adjustment on the neck and upper back musculoskeletal symptoms in an office worker. Methods: An N=1 study was conducted using the ABC design. Ethics approval was obtained for the study and the participant provided informed written consent. The participant was assessed over three four week phases as she performed her habitual computer work. The outcome measures assessed during the three phases were the pain intensity and perceived sitting comfort. The three phases were named the baseline, intervention and wash-out phases. During the baseline phase, the outcome measures were obtained at the participant‟s habitual work station. The intervention phase involved a vertical adjustment of the chair and computer screen height. The wash-out phase allowed the participant to adjust the chair and computer screen height to their choice. A follow-up interview was conducted with the participant three months after completion of the study. The mean values and the ranges of the pain intensity and perceived comfort were obtained and compared. The data collected was captured on a Microsoft Excel 2010 spread sheet, where after the data was tabulated and presented graphically. Results: The mean pain intensity of the participant increased slightly during the intervention phase in comparison to the baseline phase, but remained stable during the wash-out phase. The mean perceived sitting comfort deteriorated initially during the intervention phase, but improved later during the intervention phase and showed greater improvement during the wash out phase. The perceived sitting comfort showed more improvement than the pain intensity during the washout phase. Both the pain intensity and perceived sitting comfort showed improvement at the three months follow up assessment, post completion of the study. Conclusion: The vertical height adjustment of the chair and the VDT did not improve the participant‟s pain intensity and perceived sitting comfort when compared to the participant‟s habitual workstation parameters. The findings do not favour the horizontal viewing angle. The findings of this study however support the use of „slightly below horizontal‟ viewing angle as being conducive to reduce the pain intensity and improve the sitting comfort of an office worker.
AFRIKAANSE OPSOMMING: Doelstelling: Om die effek te bepaal van die hoogte aanpassing van die stoel en rekenaarskerm op die nek en bo-rug muskuloskeletale simptome van 'n kantoorwerker. Metodes: „n N=1 studie was uitgevoer deur gebruik te maak van die ABC ontwerp. Etiese goedkeuring was verkry vir die studie en die deelnemer het ingeligte skriftelike toestemming verleen. Die deelnemer was ge-evalueer oor drie vier week-lange fases terwyl sy haar gewone rekenaarwerk verrig het. Die uitkomsmetings ge-evalueer tydens die drie fases was pyn intensiteit en waargenome sitgemak. Die drie fases was genoem die basislyn, intervensie en uitwas fases. Gedurende die basislyn fase was die uitkomsmetings by die deelnemer se gewone werkstasie ingevorder. Die intervensie fase het 'n vertikale aanpassing van die stoel en rekenaarskerm behels. Die uitwas fase het die deelnemer toegelaat om haar stoel en rekenaarskerm se hoogte aan te pas volgens haar keuse. 'n Opvolg onderhoud was gevoer met die deelnemer drie maande na die voltooiing van die studie. Die resultate was vasgelê op 'n Microsoft Excel 2010 data bladsy, waarna die data getabuleer en grafies uitgebeeld is. Resultate: Die gemiddelde pyn intensiteit van die deelnermer het effens toegeneem tydens die intervensie fase in vergelyking met die basislyn fase, maar het stabiel gebly tydens die uitwas fase. Die gemiddelde waargenome sitgemak het aanvanklik verswak tydens die intervensie fase, maar het later verbeter tydens die intervensie fase en het aangehou verbeter tydens die uitwas fase. Die waargenome sitgemak het groter verbetering getoon as die pyn intensiteit tydens die uitwas fase. Beide pyn intensiteit en waargenome sitgemak het verbetering getoon by die drie maande opvolg evaluasie, na voltooiing van die studie. Gevolgtrekking. Die vertikale hoogte aanpassing van die stoel en rekenaarskerm het nie die deelnemer se pyn intensiteit en waargenome sitgemak in vergelyking met die deelnemer se gewone werkstasie parameters verbeter nie. Hierdie bevindinge is nie ten voordeel van die horisontale kykhoek nie. Nietemin, ondersteun die bevindinge van hierdie studie die gebruik van die "effens onder die horisontale" kykhoek as bevorderend om die pyn intensiteit te verminder en die sitgemak van 'n kantoorwerker te verbeter.

Full textAbstract:
This project examined dispositional optimism and its influence on the three subscales of marital adjustment (consensus, satisfaction, and cohesion) by gender. Data for this study came from Wave 2 and 3 of the National Survey of Families and Households. The Actor Partner Interdependence Model (APIM) was used to examine both actor and partner effects of dispositional optimism on the marital adjustment subscales using the program AMOS. Results indicate that wives’ optimism seem to influence their own later marital satisfaction as well as their husbands’ later marital satisfaction. However, husbands’ optimism appeared to influence neither their own nor their wives’ later satisfaction. These results imply that wives’ optimism matters for marital satisfaction, whereas husbands’ does not.

Full textAbstract:
Over the past two decades, Taylor (1983; Taylor & Brown, 1988) has explored the tendency of individuals to develop positive illusions in coping with stressful, or traumatic events. These illusions consist of unrealistic positive self evaluations, exaggerated perceptions of control or mastery, and unrealistic optimism. According to Taylor, illusions are important in accomplishing several tasks associated with successful adaptation, namely, search for meaning, regaining a sense of mastery, and restoring self-esteem through processes of social comparison. The purpose of the study was threefold: (a) to explore the construct of positive illusions (PI), (b) to explore employees' use of PI in coping with a stressful work event, and (c) to discover how PI, temporal distance, level of perceived stress, and a priming manipulation affect the type and frequency of inferences made while responding to items taken from a coping inventory.The study was conducted in two phases. In Phase I, 209 nurses responded to a questionnaire which identified their level of PI, perceptions of occupational climate, and job satisfaction. They were also asked to describe a stressful work situation, and their appraisals and coping strategies used to manage the event. Results demonstrated that the PI construct for this population was best identified by enhanced self-perception, high dispositional optimism, and low internal locus of control. PI were associated with high self-efficacy for resolving the stressful event, appraisals of challenge, positive reappraisal and self-controlling coping, and the nonuse of escape-avoidance coping.
In Phase II, 36 nurses "high" and "low" in PI were assigned to two priming conditions. Nurses participated in a think-aloud procedure during which time they rated 16 coping items in relation to their previously identified work event and gave reasons for their ratings. After protocol analysis, results demonstrated that, (a) the type of prime used affected the consistency of recall even after controlling for temporal distance, and (b) positive illusions, prime, and time interact to produce significantly different patterns of self-statements and contextual inferences for the four groups. The results demonstrate that measures which rely on the recall of coping strategies need to be treated with considerable caution.

Full textAbstract:
Based on a resilience framework, the purpose of this study was to address knowledge gaps about minority youths who lived in rural and poor areas, had a primary caregiver with a diagnosis of depression, and faced multiple psychosocial stressors. Three research objectives included: 1) To explore the association between ecological protective factors and four developmental outcomes-emotional adjustment, behavioral adjustment, school performance, and educational aspiration; 2) To identify the robust protective factors; and 3) To explore the interactive relationships between risk and robust protective factors. Families (N=126) where the primary caregiver had a diagnosis of major depression and had a child aged 10-14 years old were selected for this study. This study used a longitudinal data set: Family and Community Health Study (FACHS). Six theoretical protective factors in individual-family-community levels and four youths’ developmental outcomes were selected from the FACHS: emotional adjustment; behavioral adjustment; school performance; and educational aspiration. Separate hierarchical regression analyses were conducted for each of the youths’ developmental outcomes. Before conducting the regression analyses, factor analysis, power analysis, data screening and regression assumptions assessment were conducted. For the research objective 1 and 2, this study’s findings suggested that overall, with the exception of parental monitoring, these theoretical protective factors only operated in specific developmental domains. Only parental monitoring was identified as a robust protective factor for this population. The regression model (R2adj) explained 11.5 % of the variance of depression, 29.8 % of conduct behavior, 15.2 % of school performance, and 18.7 % of educational aspiration. Youths’ optimism (ß=-.215) significantly contributed to the Emotional Adjustment Model. Youths’ self control (ß=-.210), prosocial friendship (ß=-.187), and parental monitoring (ß=-.250) significantly contributed to the Behavioral Adjustment Model. Parental monitoring (ß=.189) significantly contributed to the School Performance Model. Parental monitoring (ß=.278) and teacher’s support (ß=.292) significantly contributed to the Educational Aspiration Model. For objective 3, this study suggested that the effect of parental monitoring did not vary by the risk levels. In other words, regardless of the change of risk effect, parental monitoring consistently functioned as a protective effect on youth’s educational aspiration. Based on the findings from this study, six suggestions for future research, four recommendations for intervention and mental health-related services systems, and one suggestion for social work education were provided.

Full textAbstract:
The present study examined the relationship of sense of humor to affect and coping with humor ability. The participants were 147 Introductory Psychology students from Ball State University. Participants first took the Situational Humor Response Questionnaire (SHRQ: Martin & Lefcourt, 1984), then observed 1 of 3 videos (i.e., sad, neutral, or humorous), which was then followed by the Coping with Humor Scale (CHS: Martin & Lefcourt, 1983) and the Multiple Affect Adjective Check List (MAACL: Zuckerman & Lubin, 1965). The results indicate that sense of humor is inversely related to depression and hostility regardless of video condition but not with anxiety. Low sense of humor participants were influenced greatly as a function of the video condition but the high sense of humor paticipants were not. High sense of humor paticipants used humor to cope more than the low sense of humor participants in the sad video condition. The findings indicate that sense of humor is strongly related to depression, that depression levels can be reduced with a humor stimulus, and that those with a high sense of humor are more likely to use humor to cope with problems.Department of Psychological Science

Full textAbstract:
Grounded in the Positive Youth Development (PYD) approach and in Bronfenbrenner’s ecological model of human development (1979), the current research program used a correlational approach to examine the effect of participation in organized activities (OAs) on two dimensions of youth’s psychological and emotional development: Psychological adjustment (Article 1) and Emotional competence (Article 2). Through two articles and four studies, this research program also aimed to explore the influence of two OA-context variables, youth experiences and youth engagement, on the previous dimensions of development. Together, results aimed to provide new information in the PYD research domain. Main findings are described.
First, we hypothesized that participation in OAs had a positive effect on indicators of youth psychological and emotional development. Overall, our results indicated that this effect was not statistically significant (Article 1, Study 2; Article 2, Studies 1 and 2), although some statistically significant differences were found between OA participants’ and non-participants’ psychological adjustment in a correlational design (Article 1, Study 1). The potential implications of these results, as well as their limitations, are discussed.
The current research also examined the potential role of youth experiences within their OAs in the link between OA participation and psychological and emotional development. Overall, results indicated that some experiences in OA contexts were statistically significant predictors of psychological adjustment and emotional competence. Furthermore, experiences of identity emerged as mediators of the effect of participation on life satisfaction in a longitudinal design (Article 1, Study 2). However, this effect was negative and may be best explained by the presence of a suppression effect in the model. Moreover, experiences of initiative and stress emerged as mediators of the effect of participation on emotional competence (Article 2, Study 1), but results were not replicated in a longitudinal design (Article 2, Study 2).
This research also examined the potential role of youth’s engagement in their OAs on psychological and emotional development (Article 1, Study 2; Article 2, Study 2). The inclusion of engagement in our research program was crucial and allowed for the identification of specific necessary conditions for participation to have an effect on outcomes of psychological and emotional development. In our research, engagement emerged as a moderator of the indirect effects of participation on two indicators of psychological and emotional development. First, the indirect effect of participation on self-esteem through experiences of initiative emerged as statistically significant only for youth who were highly engaged in their OA (Article 1, Study 2). Next, the negative indirect effect of participation on life satisfaction through experiences of identity emerged as significant only for youth who were highly engaged in their OA. Again, the latter result might be best explained by the presence of a suppression effect (Article 1, Study 2). Lastly, engagement also emerged as a moderator of the effect of participation on specific youth experiences (Article 1, Study 2).
Implications for theory and practice emerge from this research. A better understanding of the effect of OA participation on psychological and emotional development and of the specific roles of youth experiences and youth engagement in OAs is attained. Practical implications are discussed. In line with its exploratory nature, the current research program provides multiple avenues for future research within the PYD approach.

Full textAbstract:
The lifespan developmental framework views aging as a time of continued personal change and development. Death is perhaps the most salient developmental challenge older persons face. The relationship of self-transcendence, spirituality, and hope to personal death perspectives was the focus of this research. A descriptive correlational approach was used to study the relationships between these variables. Interviews were conducted with forty healthy adults aged sixty-five and older. Findings revealed that self-transcendence and spirituality were significantly correlated with positive death perspectives in this sample. Findings also revealed significant relationships between age and death perspectives, gender and self-transcendence, and gender and spirituality. No significant relationships were found between hope and death perspectives and hopelessness and death perspectives.

Full textAbstract:
Specific Language Impairment (SLI) is a primary language disorder that persists into adolescence and adulthood. Adolescent outcomes related to SLI have been mainly investigated from the point of view of psychopathology. This study aimed to provide a holistic view of the educational and socio-emotional competence for a group of young people with a history of SLI who have been participating in a longitudinal study from the age of 8 (Dockrell, Lindsay, Palikara, & Cullen, 2007) to the end of formal education. This was achieved by using a range of standardised and self-report assessments and interview schedules. Assessment related to educational competence revealed that adolescents with a history of SLI were at risk of experiencing continuing difficulties in the area of language and literacy at 16. However, their educational achievements as depicted by the GCSE scores provided a more positive picture when compared to the findings of earlier studies. Writing skills at 16 were found to be an important protective factor in relation to academic attainment. In respect of socioemotional competence, a picture of strengths and weaknesses concerning behavioural difficulties, self-esteem and coping skills was revealed. However, no relationship was found between language skills and socio-emotional outcomes. Additionally, these results highlighted the importance of contextual factors including family involvement and social support as for young people's emotional well-being. These findings have both educational and clinical implications. A systemic developmental approach considering individual and contextual factors but also strengths and weaknesses is put forward. Finally, the thesis provides useful directions for the development and implementation of multi-dimensional and appropriate intervention studies.

Full textAbstract:
Adolescents with cancer are surviving at improved rates with levels of psychopathology in line with their healthy peers. Thus, recent psycho-oncology research is focusing on finding significant predictors to their positive adjustment and psychosocial functioning. The author examined adolescent cancer survivors (n = 50; diagnosis age = 10 21; 2 10 years post-diagnosis) to test the mediation effects of positive emotionns (satisfaction with life, subjective happiness, and optimism) and time perspective on the outcome variables quality of life and benefit finding with demographic/medical variables (gender, number of treatments received for cancer, and previous psychotherapy) as independent variables. Results indicated that positive emotions fully mediated the relationship between the number of treatments received for cancer and quality of life and partially mediated the relationship between having engaged in psychotherapy and quality of life with adolescent cancer survivors. Importantly, results indicated that patients' with a relapse diagnosis scored significantly different than those with no relapse diagnosis on quality of life. Although positive emotions were significantly associated with scores on benefit finding in a positive direction, benefit finding did not fit two of the four criteria for mediation. Time perspective indices did not meet full criteria for significant mediation with the relationships between independent and outcome variables. Regarding time perspective indices, significant associations included: prior participating in psychotherapy was associated with higher scores on a Past-Negative time perspective, the more treatments received for cancer was associated with higher scores on a Present-Focused time perspective, and higher scores on the Past-Negative time perspective was associated with lower scores on benefit finding. Discussion centers on the use of evidence-based interventions that cultivate positive emotions with adolescent cancer survivors and the utility of implementing quality of life assessment in pediatric medical settings. Continued emphasis is placed on larger sample sizes via multi-center cooperation that may better illustrate adjustment difficulties within subgroups of this population (i.e. relapse diagnosis). Future research considerations are provided for the constructs of time perspective and benefit finding.

Full textAbstract:
This thesis was concerned with the psychological adjustment of 67 end-stage cancer patients, and three psychosocial variables considered to influence that adjustment: emotional support from spouse, positive meaning, and working models of attachment. Furthermore, this thesis was also concerned with the psychological adjustment of the patients' spouses, and the influence of emotional support from patient and working models of attachment on their adjustment. It was hypothesised that each of these psychosocial variables would directly influence the psychological adjustment of patients and spouses, measured using the negative affectivity scale of the Positive and Negative Affect Scale (PANAS). Furthermore, it was hypothesised that emotional support would influence positive meaning, and working models of attachment would influence both emotional support and positive meaning. Variables were measured via paper and pencil self-report inventories, with the exception of positive meaning, where verbal responses to an open question were coded. Univariate analyses indicated an association between patients' and spouses' emotional support provided by one another and their psychological adjustment. Univariate results also showed that patients' positive meaning was related to patients' psychological adjustment, and that patients' working models of attachment involving higher levels of attachment anxiety were associated with patients' poorer psychological adjustment. All these individual associations remained statistically significant after three control variables related to the patients' physical condition were taken into account. In addition, univariate analyses indicated that attachment was associated with emotional support, and that emotional support was associated with positive meaning. Following univariate analyses, variables were integrated into one model for patients and another for spouses using path analyses. Results were generally consistent with the prior sets of analyses. However, patients' working models of attachment involving higher levels of attachment anxiety no longer had a direct effect on patients' psychological adjustment to statistically significant levels. Rather, the influence of the working models of attachment on patients' psychological adjustment was mediated by emotional support. In addition, patients' positive meaning no longer had a significant direct effect on patients' psychological adjustment. The insignificant path coefficients between attachment anxiety and psychological adjustment, and between positive meaning and psychological adjustment, were attributed to the large amount of variance in negative affect due to emotional support. In summary, this research indicates that emotional support given and received between patients and spouses is important to the psychological adjustment of each party. Furthermore, emotional support influences patients' ability to construe positive meaning in their illness, although positive meaning does not appear to be as critical to the psychological adjustment of patients as emotional support. Working models of attachment influence the psychological adjustment of patients primarily through their influence on emotional support.

Full textAbstract:
People living with HIV/AIDS (PLH) struggle with depression. Recent research suggests that depression affects medical regimen adherence, disease progression, and risky sexual behaviors. The present study uses a stress and coping theory viewing HIV-related stigma and physical symptoms as stressors in PLH. Results suggest whereas symptoms and stigma consistently predict negative affect, positive affect, and overall depression, the role of optimism, pessimism, active coping, denial, and behavioral disengagement is not as clear. Pessimism and denial predict negative affect and depression. Optimism and behavioral disengagement predict depression and positive affect. Active coping only predicts positive affect. Focusing on positive and negative affect as distinct components that contribute to overall depression may help researchers develop interventions more effectively.

Participants of the study were 81 married couples. All 162 spouses filled out Positive and Negative Affect Schedule (PANAS), Dyadic Adjustment Scale (DAS), Communication Skills Inventory and Information Form. Additionally one spouse in each couple filled out Spouse Observation Checklist (SOC) Form A whereas the other spouse filled out SOC Form B. Spousal accuracy were assessed by partial pairwise intraclass correlation. R-to-z transformation was used to find on which PMB and NMB areas&rsquo
accuracy distressed and nondistressed couples differ. Six Repeated Measures MANOVAs were conducted to explore differences in distressed and nondistressed couples
wives and husbands
self-report and spouse-report in three evaluations of PMB and NMB. In order to find most important PMB and NMB areas&rsquo
frequencies in terms of their relationship with marital adjustment, two Roy-Bargmann Stepdown Analysis were conducted by controlling for positive affect, negative affect and communication skills. Principal component analysis was employed to the self and spouse reports of marital behavior areas&rsquo
frequencies and then two stepwise multiple regression analyses were used to identify which factors of marital behavior play a significant role in predicting marital adjustment. Results revealed that nondistressed spouses were more accurate in predicting their partners&rsquo
reports of emotional impact and attributed importance
more frequently engaging in PMB, less frequently engaging in NMB, feel more positive about and attribute more importance to PMB compared to distressed spouses. Spouse report of marital behavior explained more variance than self report of marital behavior
NMB and affectional marital behavior explained more variance than PMB in marital adjustment.

Full textAbstract:
In the present study, we examined the role of ethnoracial discrimination, social support (viz., family & friends), and hope (viz., agency & pathways) in accounting for negative psychological adjustment (viz., worry & depressive symptoms) and positive psychological adjustment (viz., vitality & life satisfaction) in a sample of 203 (164 females & 39 males) multiethnoracial adults. Results of conducting a series of hierarchical regression analyses indicated that beyond ethnoracial discrimination and social support, the inclusion of hope was found to augment the prediction model of psychological adjustment. Within the hope set, agency was found to be uniquely associated with adjustment. Pathways was found to be uniquely associated with positive indices of psychological adjustment. The present findings are the first to highlight the significance of hope in multiethnoracial adults. Some implications of the present findings for understanding psychological adjustment in multiethnoracial adults are discussed.

Full textAbstract:
In the present study, we examined the role of racial discrimination, social support (viz., family and friends), and hope (viz., agency and pathways) in accounting for negative psychological adjustment (viz., anxious and depressive symptoms) and positive psychological adjustment (viz., vitality and life satisfaction) in a sample of 249 African Americans. Overall, results of conducting a series of hierarchical regression analyses provided some evidence for the role of racial discrimination and social support in accounting for both negative and positive psychological adjustment. Noteworthy, the inclusion of hope was found to significantly augment the prediction models of psychological adjustment. Within the hope set, agency was consistently found to uniquely account for adjustment. In contrast, pathways was only found to uniquely account for vitality. Beyond affirming the importance of racial discrimination and social support, the present findings highlight the added value of considering hope, especially agency, in understanding positive and negative psychological adjustment in African Americans. Implications of the present findings for understanding the role of racial discrimination, social support, and hope in the psychological adjustment of African American adults are discussed.

Full textAbstract:
Objective: This systematic review explored how “adjustment” is generally defined in adults with an acquired visible difference (AVD) and what positive psychological factors have been evidence to be associated with positive coping and processes of adjustment in AVD. Method: A systematic search for peer reviewed journal articles from 1980 to February 2016 was conducted using: PyschINFO, Medline, EMBASE and CINAHL. Studies were appraised according to eligibility criteria and evaluated against a quality criterion to assess risk of bias. Results: Fourteen studies were included and were in the areas of head and neck cancer, burns and amputation. Selected studies demonstrated inconsistent conceptualisations of adjustment ranging from: lack of psychopathology, resilience, post-traumatic growth and quality of life. Psychological factors identified were; social functioning (social support, social self-efficacy), coping strategies (emotion, problem-focused, active coping) and dispositional optimism. Studies were considered to be of moderate methodological quality with weaknesses including; a lack of control/comparison groups, lack of measure sensitive to the unique challenges of living with AVD and minimal account for confounding variables. Results are discussed in the context of future research implications. Objective: This study aimed to explore the relationship between two dimensions of attachment insecurity (avoidance and anxiety), body image dissatisfaction and perfectionism using theoretically driven multiple mediation models that included emotion dysregulation and interpersonal problems as hypothesised mediators. Method: Fifty female outpatients seeking cosmetic surgery on the National Health Service (NHS) and 26 females interested in seeking cosmetic surgery within the public domain participated in this cross-sectional study (N=76). Participants completed measures of attachment avoidance and anxiety, body image dissatisfaction, perfectionism, emotion dysregulation and interpersonal problems. Results: Attachment insecurity was significantly associated with body image dissatisfaction and perfectionism. Interpersonal problems and emotion dysregulation also significantly partially mediated the relationship between attachment insecurity and body image dissatisfaction, specifically satisfaction with discrete aspects of body parts. Emotion dysregulation was also found to significantly partially mediate the relationship between avoidant attachment and perfectionism, but not anxiety. The clinical implications of this research are discussed.

Full textAbstract:
The effects of disability on individuals, their parents and their family as a whole have been extensively researched. However, the specific effects on siblings have not been given adequate attention by mainstream society until recently. Consequently, few services have been available for siblings in our community. Of the research that has explored sibling needs, most have relied on parental reports or used measures developed for alternate populations measuring more general variables such as psychopathology. This research project is concerned with the development of a self-report measure of Perceived Effect of Disability for teenage siblings (12 -17 years) of children with an intellectual disability and the development and pilot of an intervention that aimed to assist the positive adjustment of teenage siblings. The development of the measure involved three stages. First, an extensive item pool was constructed from past literature with 150 potential items identified. To ensure the validity of the item pool for siblings themselves, a sample of 24 teenage siblings rated the importance of the items and subscales. This reduced the number of items. Next, focus groups were run with an alternate sample of 41 teenage siblings for further evidence that all pertinent issues were included and to explore items identified as having low importance in Stage 1. The last stage involved testing the measure’s psychometric properties with a further 80 siblings. Exploratory factor analyses were conducted to determine the measure’s underlying factor structure. Results identified four factors underlying the measure, Positive Influence of Disability, Family Differences, Worry About What Others Think and Lack of Time With Others, all of which exhibited high internal consistency and test-retest reliability over a six-week period.The final measure included 40 items and included two parts, the impact on family life and the impact on social life for siblings. The issues identified through the development of the Perceived Effect of Disability measure were then used to develop a pilot intervention that aimed to assist the positive adjustment of teenage siblings. The result was a 6-week program, consisting of 90-minute groups covering Sharing My Story, Exploring Differences and Disabilities, Exploring and Communicating Feelings, Coping Skills I, Coping Skills II and Finding Meaning. The impact of the program was piloted with two groups, consisting of 16 teenage siblings (aged 12-17 years). A matched comparison sample was also used to determine if the intervention resulted in improved perceptions of the effect of disability on siblings using the Perceived Effect of Disability (PED) subscales. There was no significant interaction between time and group on any of the PED subscales. A main effect was found for time on the Lack of Time With Others subscale only. The non-significant time x group interaction, however, indicates that the main effect of time on Lack of Time With Others scores applied to both groups. There was no significant change in family functioning or self-esteem from pre to post-test for the intervention group. However, extensive qualitative data provided strong support for the importance of such an intervention for this unique group of individuals in our community.

Full textAbstract:
Il est connu que le mouvement volontaire entraîne une perturbation de la posture, qui nécessite d'être compensée par des mouvement contre-perturbateurs définis comme " ajustements posturaux ". Ce processus dynamique, qui se produit avant, pendant et après le mouvement focal, nécessite la mobilité de la chaîne posturale, avec un patron spécifique pour chaque tâche.L'objectif de cette thèse de doctorat a été d'explorer l'influence de la mobilité du rachis sur les composantes focale et posturale du transfert assis- debout, ou sit-to-stand (STS), qui est une tâche indispensable à l'autonomie fonctionnelle. Trois séries expérimentales ont évalué l'effet d'une restriction de mobilité de la colonne vertébrale sur les ajustements posturaux anticipateurs (APAs) et le mouvement focal de la tâche de STS réalisée à vitesse maximale. Des paramètres biomécaniques ont été calculés à partir des données fournies par un plateau de forces et un capteur de pression. La première série a évalué l'effet de la mobilité lombo-pelvienne au moyen de trois types de contentions lombaires, et a montré qu'une réduction du jeu articulaire de cette région était associée des APAs plus longs et plus amples, ainsi qu'à une augmentation de la durée du mouvement focal. La seconde série a mis en évidence les mêmes variations en explorant l'influence de la mobilité de la colonne cervicale au moyen de trois contentions cervicales. La dernière série s'est focalisée sur le rôle de l'augmentation de la tension musculaire le long du tronc, en utilisant un protocole spécifique de compression bimanuelle. Les résultats ont montré qu'une tension musculaire plus élevée induisait une augmentation de la durée des APAs mais sans variation de la durée du mouvement focal. L'ensemble de ces résultats suggèrent que la colonne cervicale et la colonne lombaire sont à la fois impliquées dans les composantes focale et posturale du STS, et que le maintien de leur mobilité peut favoriser l'autonomie fonctionnelle. En revanche, l'augmentation de la tension musculaire le long du tronc nécessite uniquement une réorganisation des ajustements posturaux pour maintenir le même niveau de performanceIt is well known that voluntary movements induce internal disturbances to posture, which need to be balanced by counter-pertubing movements defined as " postural adjustments ". This dynamic process, which occurs before, during, and after the focal movement, requires the mobility of the postural chain, with a specific pattern for each task. The aim of this PhD thesis was to explore the influence of spine mobility on the focal and postural components of the sit-to-stand (STS) task, which is instrumental for functional autonomy. Three series of experiments assessed the effect of spine mobility restriction on anticipatory postural adjustments (APAs) and focal movement (FM) of the STS task peformed at maximum velocity. Biomechanical parameters were calculated from force plate, and pressure sensor data. The first series assessed the effect of lumbo-pelvic mobility using three different lumbar contentions, and showed that restricted articular free play in this area was associated with longer and larger APAs, along with a higher duration of the focal movement. The second series of experiment showed the same variations when exploring the effect of cervical spine mobility using three different cervical contentions. The last series focused on the effect of increased muscular tension along the trunk, using a specific bimanual compressive load paradigm.The results showed that higher tension lead to longer APAs with no variation of FM duration. Taken together, these findings suggest that the lumbar and cervical spine are involved in both the focal and postural components of the STS task, and that preserving their articular free play might be useful to favour functionnal autonomy. In contrast, increased muscular tension along the trunk only require a reorganization of the APAs to keep the same level of task performance

Full textAbstract:
Les changements organisationnels sont actuellement de plus en plus fréquents dans le monde du travail et la réussite de leur implémentation constitue un enjeu financier et opérationnel essentiel pour les entreprises. L'objectif de ce travail doctoral était, d'une part, de contribuer à l'identification de facteurs individuels et organisationnels qui participent au développement d'attitudes positives et d'un ajustement favorable des salariés en contexte de changements organisationnels et d'autre part, d'explorer les mécanismes explicatifs sous-jacents à ces relations. Trois études ont été menées pour répondre à cet objectif. La première a démontré qu'en contexte de déménagement, le soutien socioprofessionnel et l'attachement au lieu de travail étaient respectivement corrélés positivement et négativement avec la satisfaction anticipée vis-à-vis du changement, via la médiation de la justification perçue du changement. La seconde étude a prouvé qu’en contexte d'implémentation d'un Enterprise Resource Planning (ERP) le capital social était positivement associé à trois formes d'ajustement des personnels (i.e., à la tâche, intrapersonnel et interindividuel) et que cette relation était médiée par la clarté de rôle. Enfin, la troisième étude a permis d'enrichir les précédents résultats en montrant que dans ce même contexte, plus un individu a une réaction émotionnelle favorable vis-à-vis d'un changement, plus l'engagement affectif dans le changement apparaît comme un mécanisme explicatif dans la relation entre la qualité de la communication organisationnelle liée au changement et les indicateurs de satisfaction concernant le changement (i.e., adéquation tâche-technologie et satisfaction vis-à-vis du changement). Ces trois études élargissent les connaissances scientifiques sur les attitudes et les comportements individuels dans le cadre de changements organisationnels et contribuent à la réflexion sur les actions organisationnelles favorables à la réussite de ces transformations.Mots clés : changement organisationnel, déménagement, ERP, soutien social, attachement au lieu de travail, justification perçue du changement, satisfaction anticipée, capital social, ajustement, communication sur le changement, adéquation tâche-technologie, engagement affectif dans le changement, réaction émotionnelle positiveOrganizational changes tend to be more and more frequent for businesses and a successful implementation is a financial and operational challenge for them. The main purpose of this doctoral dissertation was (1) to contribute to identifying individual and organizational factors that develop positive attitudes and adjustment, in time of organizational change, (2) to explore the mechanisms underlying such effects. Three studies were conducted. Study 1 showed that, when a corporate relocation is carried out, social support is positively correlated to anticipated change satisfaction, while workplace attachment is negatively correlated to it. Moreover, our results indicated that, perception of change justification is a mediator in those relationships. Study 2 found that, in time of Enterprise Resource Planning's (ERP) implementation, social capital was positively related to three forms of adjustment (i.e., task, intrapersonal and inter-individual adjustment) through role clarity. At last, study 3 exposed that, in that same context, the more an individual has a positive reaction to change, the more affective commitment to change appears as an explanatory mechanism between the quality of organizational communication on change and change satisfaction indicators (i.e., Task-Technology Fit and change satisfaction). As a whole, all three studies help to expand scientific knowledge on organizational changes and contribute to opening a discussion on positive organizational actions that support change success.Keyword : organizational change, corporate relocation, ERP, social support, workplace attachment, change justification, anticipated change satisfaction, social capital, adjustment, quality of change communication, task technology fit, change satisfaction, affective commitment to change, positive reaction to change

Nous avons réalisé une étude longitudinale qui se veut descriptive et corrélationnelle. Les données indiquent que 42.7% des étudiants interrogés présentent des signes de détresse psychologique. Nos résultats révèlent que plusieurs facteurs sont associés à cette détresse d’une manière statistiquement significative, à savoir la satisfaction des conditions socioéconomiques, le choix de la filière (subi ou choisi), la satisfaction du soutien social et des conditions de l’hébergement au campus universitaire. Certains facteurs transactionnels sont corrélés d’une manière significative à notre variable dépendante «la santé psychologique», à savoir le stress perçu et les stratégies d’ajustement et avec certains facteurs de personnalité comme l’estime de soi, le névrosisme et l’espoir. L’analyse des régressions multiples indique que l’estime de soi et le névrosisme expliquent, respectivement à 31% et 7%, la variance santé psychologique. Les résultats de l’étude longitudinale montrent l’amélioration générale de l’état de santé des étudiants interrogés lors du deuxième moment de l’étude avec un impact statistiquement significatif des facteurs de l’estime de soi et du coping centré sur la résolution des problèmes et l’espoirOur thesis focuses on the assessment of the psychological health of first-time Tunisian students and the psychosocial factors that can impact their health. Our study is descriptive, prospective, correlational and regressive.The data indicate that 42.7% of the students questioned show signs of psychological distress. Our results reveal that several factors are associated with this distress in a statistically significant way, namely the socioeconomic level of the students, the choice of the research, undergone or chosen, the satisfaction of social support and the conditions of accommodation on Campus University. Certain transactional factors aresignificantly correlated with our dependent variable "psychological health", namely perceived stress and adjustment strategies and with certain personality factors such as self-esteem, neuroticism and hope. Multiple regression analyses indicate that self-esteem and neuroticism account for 31% and 7% of the variance in psychological health, respectively. The results of this longitudinal study show improvement in the general state of health of the students questioned during the second moment of the study, with a statistically significant impact of the factors of self-esteem and coping centered on the resolution of problems and hope

In general, the technologies and fabrications of roll to roll (R2R) have been gradually developed for large area applications and low-cost manufacturing. Most studies investigated the printing velocity, the printing resolution, and the printing moisture of the R2R fabrications. Few studies have focused on the multi-layer printing for various colors using same printing cylinders. Therefore, this thesis proposes an automatic adjustment of printing patterned position for R2R machine that based on a constant velocity and a various velocity during printing. The R2R printing machine is used for printed and unprinted patterns of varying bag lengths. The aim is to solve the problems of the traditional ones changing the roller sizes when printing. Furthermore, the implementation of the printing technologies that based on the programmable logic controller (PLC) and the human-machine interface (HMI) were demonstrated. The R2R machine system includes two stepper motors with control drivers, a print roller, a PLC, a HMI, and sensors. The control parameters of required length, produced quantity, and speed of the printing machine are investigated. One of the experimental results that the finished product error in this study with within two millimeters shows the R2R way is feasible but needs to be adjusted and improved. Therefore, this study provides the fully automatic adjustment of printing R2R machine that designed according to the demand of market; it can provide different specifications and different shape bags with high quality.

With advances in technology, the incidence of chronic disease is increasing as the global life expectancy is rising. Dementia is one of the common diseases in the elderly. This illness usually leads to great impact in their life, body health, sentiments and eventually cause them to lose self-care abilities. Those patients may not recognize the way home that becomes a huge problem and burden to themselves, the caretakers and society. However, there’s indeed room for improvement and suggestion of the investigation programs nowadays. Therefore, this thesis aims at providing a system platform which is based on iBeacon technology that is using the Bluetooth 4.0 to solve problems of detecting distance, power consumption and privacy protection. In addition, about the problem of converted distance of wireless detect, we propose a solution by using Gaussian filter and clustering, to provide the different values of RSSI(Received Signal Strength Indicator) determined for the different values of Path Loss Exponent, which to promote precision of range conversion and orientation.
