The Relationship Between Youth Risk-Taking Behaviour and Activity Engagement

Youth have been found to engage in various risk-taking behaviours at higher rates than any other age group. However, there is a lack of research on the division between adaptive and maladaptive risk behaviours among adolescents and emerging adults. Adaptive risk-taking behaviours may present youth with ways to successfully partake in the risk behaviours that they are naturally inclined to engage in. The relationship between activity engagement and positive youth development has been extensively studied and cited as a way to expose youth to positive experiences and promote successful development. However, the relationship between activity engagement and risk behaviours among youth has yetto be studied in depth. This study investigated the potential relationship between various adaptive and maladaptive risk behaviours and activity engagement among youth, through an indirect link through five mediator variables. These potential mediators represented the three systems in Jessor's Problem Behaviour Theory. Participants included 276 youth (M = 19.06 years, SD = 1.60, 89.1 % female) from Brock University. Results revealed that activity engagement significantly predicted greater adaptive social risk behaviours among youth. However, there was no mediating effect through the problem behaviour systems. Correlations revealed that being male was associated with more maladaptive risk behaviours and fewer adaptive risk behaviours than females. Additionally, behavioural engagement specifically related to less maladaptive physical health risks and psychological engagement related to greater adaptive social risks. Overall, these findings suggest that activity engagement may be differentially related to the various types of risk-taking and gender associations may exist between the various types and dimensions of risk behaviours, but future work is needed to understand the variables that may explain such relationships.

Postcolonial entanglements of Power, Race, Class and Privilege in Child and Youth Care Work Within a Brazilian Favela

This research assesses the various aspects of Child and Youth Care (CYC) work and how relationships between child or youth and care provider are limited and constricted within greater political, social and historical contexts. Specifically, this research takes place internationally in Rio de Janeiro, Brazil within a favela (slum) and unveils the entangled and complex relationship that I, not only as an ethnographer, but also as a CYC worker had with the many young people that I encountered. It will address a variety of theories that demonstrate the potentials of reproducing oppressive relationships, and argue that it is imperative for CYC workers to critically reflect on the greater contexts in which their work is situated in order to gain forces with those young people whom they are attempting to serve.

Relationship Building with Aboriginal Elders in the Publicly Funded Secondary School Classroom: A Study of Ethical Space from an Aboriginal Persepective

This is a current story of ethical space in education that is often neglected in the design of educational experiences for Aboriginal students. This story is told through an Aboriginal lens rooted in the structured Two Row Wampum Belt relational agreement between Aboriginal peoples and Settlers. Through ethnographic narrative based on an extensive literature review, individual in-depth interviews, and a personal journal, this study documents the processes of acceptance, silence, complications, and then rejection to position Aboriginal Elders as inclusive bodies of knowledge in publicly funded secondary school classrooms. Aboriginal Elders are valued as Knowledge Holders, as Aboriginal teachers, guides, and mentors. Yet, the complexities of colonial rights, politics, and policies continue to intrude deeply into the lives of Aboriginal peoples to cause silence, confusion, and struggle rather than an evolution of new knowledge amongst two co-existing solitudes under the original terms of the Two Row Wampum Belt. The study was delayed and then came to an end when the school boards and local schools scrutinized its operating policies and unresolved funding issues. This study demonstrated that despite the Two Row Wampum Belt agreement that promised a co- existent relationship between Aboriginal peoples and Settlers, the strategy of inviting Aboriginal Elders to work alongside teachers in the classroom was viewed as being in conflict with the Settler’s institutional/educational objectivities, and, as such, was denied to Aboriginal students.

Work, personality and psychological distress : direct and moderating effects of the Big Five personality traits

L’objectif de ce mémoire est d’examiner les nombreuses associations qui existent entre les conditions de l’organisation du travail, les traits de personnalité et la détresse psychologique au travail. La question de recherche principale était : est-ce que les cinq grands traits de personnalité (Big Five personality traits) ont un effet modérateur sur la relation entre les conditions de l’organisation du travail et la détresse psychologique. De nombreuses autres questions ont aussi été considérées. Pour répondre aux vingt-et-une hypothèses proposées dans cette recherche, nous avons utilisé des données secondaires d’une étude transversale de 395 employés d’un service de police municipal. À la suite d’analyses multivariées, nous avons pu observer quatre associations significatives. Concernant les conditions de l’organisation du travail, nous avons trouvé que les demandes psychologiques en milieu de travail augment la détresse psychologique, tandis que le support d’un superviseur la diminue. En ce qui concerne, les traits de personnalité, nous avons trouvé qu’être névrotique (neuroticism) augmente la détresse psychologique. Finalement, nous avons trouvé un effet modérateur du trait de personnalité, être consciencieux (conscientiousness), sur la relation entre les demandes psychologiques et la détresse psychologique. Bref, nos résultats nous indiquent que les cinq grands traits de personnalité (Big Five personality traits) ont une influence mitigée sur la santé mentale en milieu de travail.

Work design and conflict in the workplace : the moderating effect of personality

La présente recherche a pour objectif d’étudier les effets que peuvent exercer la conception du travail sur le type de conflit qui émerge en milieu de travail. La notion de conception du travail se divise en trois dimensions, soit les caractéristiques reliées à la tâche, les caractéristiques reliées aux connaissances et les caractéristiques sociales. Ces dimensions sont mises en relation avec les deux types de conflit en milieu de travail, soit le conflit relié à la tâche et le conflit relié à la relation. Cette recherche vise également à vérifier l’effet modérateur des traits de personnalités sur les relations entre les dimensions de la conception du travail et celles du conflit en milieu de travail. Cette recherche est basée sur 473 participants qui occupent un emploi rémunéré et qui ont vécu une situation de conflit en milieu de travail allant jusqu’à 6 mois avant la période de sondage, allant du 14 au 18 janvier 2012. Les résultats indiquent qu’il n’y a pas de relations particulières entre la conception du travail et le type de conflit en milieu de travail. En ce qui a trait aux effets des traits de personnalité, les résultats indiquent que ces variables n’ont aucuns effets modérateurs sur la relation entre la conception du travail et le type de conflit en milieu de travail. Globalement, les résultats ne démontrent aucune relation entre la conception du travail et les types de conflit en milieu de travail, ou les effets modérateurs que les traits de personnalités peuvent avoir sur ces relations.

Partner behavioral responses to pain mediate the relationship between partner pain cognitions and pain outcomes in women with provoked vestibulodynia.

Partner behavioral responses to pain can have a significant impact on patient pain and depression, but little is known about why partners respond in specific ways. Using a cognitive-behavioral model, the present study examined whether partner cognitions were associated with partner behavioral responses, which prior work has found to predict patient pain and depressive symptoms. Participants were 354 women with provoked vestibulodynia and their partners. Partner pain-related cognitions were assessed using the partner versions of the Pain Catastrophizing Scale and Extended Attributional Style Questionnaire, whereas their behavioral responses to pain were assessed with the Multidimensional Pain Inventory. Patient pain was measured using a numeric rating scale, and depressive symptoms were assessed using the Beck Depression Inventory–II. Path analysis was used to examine the proposed model. Partner catastrophizing and negative attributions were associated with negative partner responses, which were associated with higher patient pain. It was also found that partner pain catastrophizing was associated with solicitous partner responses, which in turn were associated with higher patient pain and depressive symptoms. The effect of partner cognitions on patient outcomes was partially mediated by partner behavioral responses. Findings highlight the importance of assessing partner cognitions, both in research and as a target for intervention. Perspective The present study presents a cognitive-behavioral model to partially explain how significant others' thoughts about pain have an effect on patient pain and depressive symptoms. Findings may inform cognitive-behavioral therapy for couples coping with PVD.

An Analysis of Work Related Stress Factor in Selected Industries in Kerala ,India

Occupational stress is becoming a major issue in both corporate and social agenda .In industrialized countries, there have been quite dramatic changes in the conditions at work, during the last decade ,caused by economic, social and technical development. As a consequence, the people today at work are exposed to high quantitative and qualitative demands as well as hard competition caused by global economy. A recent report says that ailments due to work related stress is likely to cost India’s exchequer around 72000 crores between 2009 and 2015. Though India is a fast developing country, it is yet to create facilities to mitigate the adverse effects of work stress, more over only little efforts have been made to assess the work related stress.In the absence of well defined standards to assess the work related stress in India, an attempt is made in this direction to develop the factors for the evaluation of work stress. Accordingly, with the help of existing literature and in consultation with the safety experts, seven factors for the evaluation of work stress is developed. An instrument ( Questionnaire) was developed using these seven factors for the evaluation of work stress .The validity , and unidimensionality of the questionnaire was ensured by confirmatory factor analysis. The reliability of the questionnaire was ensured before administration. While analyzing the relation ship between the variables, it is noted that no relationship exists between them, and hence the above factors are treated as independent factors/ variables for the purpose of research .Initially five profit making manufacturing industries, under public sector in the state of Kerala, were selected for the study. The influence of factors responsible for work stress is analyzed in these industries. These industries were classified in to two types, namely chemical and heavy engineering ,based on the product manufactured and work environment and the analysis is further carried out for these two categories.The variation of work stress with different age , designation and experience of the employees are analyzed by means of one-way ANOVA. Further three different type of modelling of work stress, namely factor modelling, structural equation modelling and multinomial logistic regression modelling was done to analyze the association of factors responsible for work stress. All these models are found equally good in predicting the work stress.The present study indicates that work stress exists among the employees in public sector industries in Kerala. Employees belonging to age group 40-45yrs and experience groups 15-20yrs had relatively higher work demand ,low job control, and low support at work. Low job control was noted among lower designation levels, particularly at the worker level in these industries. Hence the instrument developed using the seven factors namely demand, control, manager support, peer support, relationship, role and change can be effectively used for the evaluation of work stress in industries.

Relationship among children’s perception of parental relationship and parental empathy and prosocial behaviour during childhood

The objective of this work is to study if children’s perception of parental relationship and parental empathy can predict prosocial behaviour during childhood. The sample was composed of 934 Argentine children, aged 9 to 12, of middle socio-economical level. The participants completed Argentine scale of Children Perception of Parental relationship (richaud de Minzi, 2007), an Argentine adaptation of scale of Prosocial Behaviour (Caprara and Pastorelli, 1993) and a questionnaire to measure children’s perception of parental empathy (richaud de Minzi, 2006). structural equations modelling (sEM) analyses were conducted to explore our hypotheses. Six theoretical models fit the data very well. The results showed that parental styles of acceptance and pathological control impact on children prosocial behavior. Children’s perception of parental empathy was positively associated with children prosocial behavior. Finally, parental acceptance and pathological control were associated with children’s perception of parental empathy, but negligent parental behaviour did not.  

Work-family conflict, burnout and work engagement among teachers: The moderating effect of job and personal resources

The present study contributes to the literature on the Job Demands-resources model in the italian school context. the aim of this paper is to examine how the interaction between work-family conflict (i.e., a typical job demand) and opportunities to learn and to develop and self-efficacy (i.e., typical job and personal resources, respectively) affect the core dimensions of burnout (exhaustion and depersonalization) and work engagement (vigor and dedication). Hypotheses were tested with a cross-sectional design among 143 teachers of a junior high school in the north of Italy. Results of moderated multiple regression analysis partially supported the hypotheses as the opportunities to learn and to develop buffered against the aversive effects of work-family conflict on depersonalization, whereas self-efficacy moderated the relationship between work-family conflict and vigor. From a practical viewpoint, our findings suggest that opportunities to learn and to develop and self-efficacy are important re- sources that help teachers to reduce the negative effects related to work-family conflict.

Job satisfaction in a developing country: exploring the work-family rivalry

This paper empirically analyzes the relationship between familiar duties and job satisfaction in a developing country by using four different indexes. This analysis includes objective measures and subjective measures from data gathered in Colombia. In contrast to previous literature, objective measures are included through the interactive effects between the family responsibilities variables and the gender. Subjective measures are evaluated using the job-family compatibility perception. Our findings show that women tend to be less satisfied at work as the number of children increases, while men are more prone to satisfaction at work when they are single thus showing the importance given to the use of their own time. It also reveals that job- family compatibility is an important determinant of job satisfaction.

The relationship between multi-species catch and effort: among fishery comparisons

The control of fishing mortality via fishing effort remains fundamental to most fisheries management strategies even at the local community or co-management level. Decisions to support such strategies require knowledge of the underlying response of the catch to changes in effort. Even under adaptive management strategies, imprecise knowledge of the response is likely to help accelerate the adaptive learning process. Data and institutional capacity requirements to employ multi-species biomass dynamics and age-structured models invariably render their use impractical particularly in less developed regions of the world. Surplus production models fitted to catch and effort data aggregated across all species offer viable alternatives. The current paper seeks models of this type that best describe the multi-species catch–effort responses in floodplain-rivers, lakes and reservoirs and reef-based fisheries based upon among fishery comparisons, building on earlier work. Three alternative surplus production models were fitted to estimates of catch per unit area (CPUA) and fisher density for 258 fisheries in Africa, Asia and South America. In all cases examined, the best or equal best fitting model was the Fox type, explaining up to 90% of the variation in CPUA. For lake and reservoir fisheries in Africa and Asia, the Schaefer and an asymptotic model fitted equally well. The Fox model estimates of fisher density (fishers km−2) at maximum yield (iMY) for floodplain-rivers, African lakes and reservoirs and reef-based fisheries are 13.7 (95% CI [11.8, 16.4]); 27.8 (95% CI [17.5, 66.7]) and 643 (95% CI [459,1075]), respectively and compare well with earlier estimates. Corresponding estimates of maximum yield are also given. The significantly higher value of iMY for reef-based fisheries compared to estimates for rivers and lakes reflects the use of a different measure of fisher density based upon human population size estimates. The models predict that maximum yield is achieved at a higher fishing intensity in Asian lakes compared to those in Africa. This may reflect the common practice in Asia of stocking lakes to augment natural recruitment. Because of the equilibrium assumptions underlying the models, all the estimates of maximum yield and corresponding levels of effort should be treated with caution.

The relationship between membrane damage, release of protein and loss of viability in Escherichia coli exposed to high hydrostatic pressure

The aim of this work was to examine a possible association between resistance of two Escherichia coli strains to high hydrostatic pressure and the susceptibility of their cell membranes to pressure-induced damage. Cells were exposed to pressures between 100 and 700 MPa at room temperature (~20C) in phosphate-buffered-saline. In the more pressure-sensitive strain E. coli 8164, loss of viability occurred at pressures between 100 MPa and 300 MPa and coincided with irreversible loss of membrane integrity as indicated by uptake of propidium iodide (PI) and leakage of protein of molecular mass between 9 and 78 kDa from the cells. Protein release increased to a maximum at 400 MPa then decreased, possibly due to intracellular aggregation at the higher pressures. In the pressure-resistant strain E. coli J1, PI was taken up during pressure treatment but not after decompression indicating that cells were able to reseal their membranes. Loss of viability in strain J1 coincided with the transient loss of membrane integrity between approximately 200 MPa and 600 MPa. In E. coli J1 leakage of protein occurred before loss of viability and the released protein was of low molecular mass, between 8 and 11 kDa and may have been of periplasmic origin. In these two strains differences in pressure resistance appeared to be related to differences in the ability of their membranes to withstand disruption by pressure. However it appears that transient loss of membrane integrity during pressure can lead to cell death irrespective of whether cells can reseal their membranes afterwards.

The relationship between land–ccean surface temperature contrast and radiative forcing

Previous work has demonstrated that observed and modeled climates show a near-time-invariant ratio of mean land to mean ocean surface temperature change under transient and equilibrium global warming. This study confirms this in a range of atmospheric models coupled to perturbed sea surface temperatures (SSTs), slab (thermodynamics only) oceans, and a fully coupled ocean. Away from equilibrium, it is found that the atmospheric processes that maintain the ratio cause a land-to-ocean heat transport anomaly that can be approximated using a two-box energy balance model. When climate is forced by increasing atmospheric CO2 concentration, the heat transport anomaly moves heat from land to ocean, constraining the land to warm in step with the ocean surface, despite the small heat capacity of the land. The heat transport anomaly is strongly related to the top-of-atmosphere radiative flux imbalance, and hence it tends to a small value as equilibrium is approached. In contrast, when climate is forced by prescribing changes in SSTs, the heat transport anomaly replaces ‘‘missing’’ radiative forcing over land by moving heat from ocean to land, warming the land surface. The heat transport anomaly remains substantial in steady state. These results are consistent with earlier studies that found that both land and ocean surface temperature changes may be approximated as local responses to global mean radiative forcing. The modeled heat transport anomaly has large impacts on surface heat fluxes but small impacts on precipitation, circulation, and cloud radiative forcing compared with the impacts of surface temperature change. No substantial nonlinearities are found in these atmospheric variables when the effects of forcing and surface temperature change are added.
