Work-life balance benefits:employee attitudes and behaviors through the lens of social exchange theory

The question of what to provide employees in order that they reciprocate with desirable behaviors in the work place has resulted in a great amount of work in the area of social exchange. Although offering fair compensation, including salary or wages and employee benefits, has been extensively studied, the effects of offering specific types of benefits, such as work-life balance benefits, and the intangible rewards that such an offering inadvertently offers, has only been minimally explored. Utilizing past literature, this current research examined the offering of work-life balance benefits, the value employees place on those benefits, the communication of the benefits by the organization to employees, and their effect on employee attitudes and behaviors. The goal was to identify the effect on desirable outcomes when work-life balance benefits are offered to determine the usefulness to the organization of offering such benefits. To test these effects, a study of an organization known to offer a strong work-life balance benefits package was undertaken. This was accomplished through the distribution of questionnaires to identify the possible relationships involving 408 employee respondents and their 79 supervisors. This was followed with interviews of 12 individuals to ascertain the true reasons for links observed through analysis. Analysis of the data was accomplished through correlation analysis, multilevel analysis and regression analysis generated by SPSS. The results of the quantitative analysis showed support for a relationship between the offering of work-life balance benefits and perceived organizational support, perceived distributive justice, job satisfaction and OCBO. The analysis also showed a lack of support for a relationship between the offering of work-life balance benefits and organizational commitment, OCBI and IRB. The interviews offered possible reasons for the lack of support regarding the relationship between the offering of work-life balance benefits and organizational commitment as well as organizational citizenship behaviors (OCBI and IRB). The implications of these findings on future research, theory and practice in the offering of work-life balance benefits are discussed.

Life cycle assessment in the food supply chain:a case study

This research aims at assessing the environmental impact of the poultry supply chain from cradle to grave using case study research and also life cycle assessment (LCA). While a limited number of generic poultry production LCA studies have been published, fewer yet assess the whole process of a specific organisation, none comparing the increased impact of further processing. Our results show that irrespectively of the impact assessment method utilised, the process of producing portions is considerably higher in total environmental impact due to the extra raw material required to produce the same mass into retail. Our research contributes to the growing number of LCA studies and could be used by practitioners for comparison against national and international averages. From a theoretical point of view, this research provides new insights into the relationship between vertically integrated supply chains and environmental performance which has not been examined in the past.

Bringing engineering education to life:an empirical approach

This paper focuses upon the argument that the role played by the engineering profession within today's society has changed markedly over the past several years from providing the foundations for contemporary life to leading societal change and becoming one of the key driver's of future social development. Coining the term 'Engineering-Sociology' this paper contributes to engineering education and engineering education research by proposing a new paradigm upon which future engineering education programmes and engineering education research might build. Developed out of an approach to learning and teaching practice, Engineering-Sociology encapsulates both traditional and applied approaches to engineering education and engineering education research. It suggests that in order to meet future challenges there is a need to bring together what are generally perceived to be two diametrically opposed paradigms, namely engineering and sociology. Building on contemporary theoretical and pedagogical arguments in engineering education research, the paper concludes that by encouraging engineering educators to 'think differently', Engineering-Sociology can provide an approach to learning and teaching that both enhances the student experience and meets the changing needs of society.

Reckoning With Apartheid: The Conundrum of Working Through the Past, An Introduction

From April 26-29, 1994, South Africa held its first universal, democratic elections. Witnessed by the world, South Africans of all races waited patiently in line to cast their ballots, signaling the official and symbolic birth of the “new” South Africa. The subsequent years, marked initially with euphoric hopes for racial healing enabled by institutional processes such as the Truth and Reconciliation Commission (TRC), have instead, most recently, inspired deep concern about epidemic levels of HIV/AIDS, violent crime, state corruption, and unbridled market reforms directed at everything from property to bodies to babies. Now, seemingly beleaguered state officials deploy the mantra “TINA” (There Is No Alternative [to neoliberal development]) to fend off criticism of growing income and wealth disparities. To coincide, more or less, with the anniversary of 1994—less to commemorate than to signal something about the trajectory of the past twenty years—we are proposing an interdisciplinary, special theme section of Comparative Studies in South Asia, Africa, and the Middle East (CSSAAME) entitled “The Haunted Present: Reckoning After Apartheid” (tentative title). The special theme section is framed around questions of reckoning in the double sense of both a moral and practical accounting for historical injury alongside the challenges and failures of the no-longer “new” South Africa. Against accounts depicting the liberation era as non-violent and peaceable, more nuanced analysis we argue suggests not only that South Africa’s “revolution” was marked by both collective and individual violence—on the part of the state and the liberation movements—but that reckoning with the present demands of scholars, the media, and cultural commentators that they begin to grapple more fully with the dimensions and different figurations of South Africa’s violent colonial history. Indeed, violence and reckoning appear as two central forces in contemporary South African political, economic, and social life. In response, we are driven to pose the following questions: In the post-apartheid period, what forms of (individual, structural) violence have come to bear on South African life? How does this violence reckon with apartheid and its legacies? Does it in fact reckon with the past? How can we or should we think about violence as a response to the (failed?) reckoning of state initiatives like the TRC? What has enabled or enables aesthetic forms—literature, photography, plastic arts, and other modes of expressive culture—to respond to the difficulties of South Africa’s ongoing transition? What, in fact, would a practice or ethic of reckoning defined in the following way look like? ˈrekəniNG/ noun: • the action or process of calculating or estimating something: last year was not, by any reckoning, a particularly good one; the system of time reckoning in Babylon • a person’s view, opinion, or judgment: by ancient reckoning, bacteria are plants • archaic, a bill or account, or its settlement • the avenging or punishing of past mistakes or misdeeds: the fear of being brought to reckoning there will be a terrible reckoning (Oxford English Dictionary) Looking back on the period, just before 1994, is sobering indeed. At the time, many saw in the energies and courage of those fighting for liberation the possibilities of a post-racial, post-conflict society. Yet as much as the new was ushered in, old apartheid forms lingered. Recalling Nadine Gordimer’s invocation of Gramsci’s “morbid symptoms” more and more it seems “the old is dying and the new cannot be born” (Gramsci cited in Gordimer 1982). And even as the new began to emerge other forces—both internal and external to South Africa—redefined the conditions for transformation. The so-called “new” South Africa, as Jennifer Wenzel has argued, was really more than anything “the changing face of old oppressions” (Wenzel 2009:159). The implications for our special theme section of CSSAAME are many. We begin by exploring the gender, race, and class dimensions of contemporary South African life by way of its literatures, histories, and politics, its reversion to custom, the claims of ancestors on the living, in brief, the various cultural expressive modes in which contemporary South Africa reckons with its past and in so doing accounts, day by day, for the ways in which the present can be lived, pragmatically. This moves us some distance from the exercise in “truth and reconciliation” of the earlier post-transition years to consider more fully the nature of post-conflict, the suturing of old enmities in the present, and the ways of resolving those lingering suspicions both ordinary and the stuff of the dark night of the soul (Nelson 2009:xv).

Exploring Intrinsic Gender Identity Using Second Life

Virtual Worlds (VWs) provide an environment to understand and explore notions of gender and identity, particularly given the ability for users to experiment with gender in online worlds. Our study analyses gender identity using the virtual space of Second Life (SL) to explore experiences and responses to gender in an avatar. We introduced 46 novice users to the VW of SL in order to see if real life gender influenced their choices of avatar. Participants selected the gender of their original avatar and once they were used to SL, they were then asked to change the gender of that avatar. We used mixed methods research consisting of paper based questionnaires (n=34) and focus groups (n=46) conducted in SL. Nearly all participants chose an initial avatar that reflected their real-life gender with females (n=22) reporting higher levels of identification with this initial avatar. Females were significantly more concerned with the gender-specific appearance of their initial avatar. On swapping gender, females reported higher levels of discomfort and many changed back before 7 minutes. Males (n=24) did not report significant discomfort with their changed-gender avatar and did not revert back to their original avatar as quickly. Our findings suggest that female participants in this study tended to reinforce gender binaries through such things as clothing, hairstyles and behaviors of their avatars. Male participants were less likely to experience discomfort through changing the gender of their avatar (with the males noting they still perceived an avatar with a female appearance as male).

Towards Empowerment: Narrative Study of Counselling Psychology Trainees and How They Make Sense of Their Personal and Professional Development in the Context of Their Past Experiences

The discipline of counselling psychology continues to grow and change in response to social, economic and political pressures. It has been argued that its quest for a coherent and distinct identity, which emphasises the possibility of the coexistence of multiple approaches, creates an inherently uncertain and dilemmatic training environment that may hinder the development of trainees’ professional identities. In order to gain a deeper understanding of the issue at hand, the aim was to explore how final year trainees and newly qualified counselling psychologists constructed and made sense of their emerging professional identities and what experiences, past and present, they drew upon in the context of their training to shape those identities. Applying narrative inquiry to analyse eight open-ended interviews, eight preliminary themes were originally identified in participants’ narratives, which with further refinements lead to stories of struggle and marginalisation, growth and discovery, and power and resilience. Participants’ stories of struggle and marginalisation emerged in reference to early family dynamics and stressful life experiences, which seemed to also foster a strong identification with the counselling psychology profession, while stories of growth and discovery focused on the importance of having supportive figures, who helped to instill a sense of security and create an atmosphere of openness. It was in this learning environment that participants felt it was possible to develop a more resilient, empowered professional self, which allowed them to shed an earlier sense of struggle and vulnerability. However, where more of an emphasis was placed on power and resilience, there seemed to be less room for participants to express other feelings that came into conflict with their preferred sense of professional self. While there seems to be a need for a ‘safer’ climate, in which trainees could voice and acknowledge anxieties, vulnerabilities and limitations, addressing concerns around power and vulnerability that may be contributing to the silencing of particular voices and identities may be equally important if trainees are to develop coherent and distinct counselling psychologist identities.

Resource use and greenhouse gas emissions from grain-finishing beef cattle in seven Australian feedlots: a life cycle assessment

Grain finishing of cattle has become increasingly common in Australia over the past 30 years. However, interest in the associated environmental impacts and resource use is increasing and requires detailed analysis. In this study we conducted a life cycle assessment (LCA) to investigate impacts of the grain-finishing stage for cattle in seven feedlots in eastern Australia, with a particular focus on the feedlot stage, including the impacts from producing the ration, feedlot operations, transport, and livestock emissions while cattle are in the feedlot (gate-to-gate). The functional unit was 1 kg of liveweight gain (LWG) for the feedlot stage and results are included for the full supply chain (cradle-to-gate), reported per kilogram of liveweight (LW) at the point of slaughter. Three classes of cattle produced for different markets were studied: short-fed domestic market (55–80 days on feed), mid-fed export (108–164 days on feed) and long-fed export (>300 days on feed). In the feedlot stage, mean fresh water consumption was found to vary from 171.9 to 672.6 L/kg LWG and mean stress-weighted water use ranged from 100.9 to 193.2 water stress index eq. L/kg LWG. Irrigation contributed 57–91% of total fresh water consumption with differences mainly related to the availability of irrigation water near the feedlot and the use of irrigated feed inputs in rations. Mean fossil energy demand ranged from 16.5 to 34.2 MJ lower heating values/kg LWG and arable land occupation from 18.7 to 40.5 m2/kg LWG in the feedlot stage. Mean greenhouse gas (GHG) emissions in the feedlot stage ranged from 4.6 to 9.5 kg CO2-e/kg LWG (excluding land use and direct land-use change emissions). Emissions were dominated by enteric methane and contributions from the production, transport and milling of feed inputs. Linear regression analysis showed that the feed conversion ratio was able to explain >86% of the variation in GHG intensity and energy demand. The feedlot stage contributed between 26% and 44% of total slaughter weight for the classes of cattle fed, whereas the contribution of this phase to resource use varied from 4% to 96% showing impacts from the finishing phase varied considerably, compared with the breeding and backgrounding. GHG emissions and total land occupation per kilogram of LWG during the grain finishing phase were lower than emissions from breeding and backgrounding, resulting in lower life-time emissions for grain-finished cattle compared with grass finishing.

"I’ll call you when we are ready" (One family’s experience of critical care and end of life decision making)

The purpose of this paper is to explore through narrative accounts one family's expérience of critical care, after the admission of a family member to an Intensive Care Unit (ICU) and their subséquent death five weeks later. Numerous studies support the need for effective communication and clear information to be given to the family. In this instance it was évident from their stories that there were numerous barriers to communication, including language and a lack of insight into the needs of the family. Many families do not understand the complexities of nursing care in an ICU so lack of communication by nursing staff was identified as uncaring behavior and encounters. Facilitating a family's proximity to a dying patient and encouraging them to participate in care helps to maintain some sensé of personal control. Despite a commitment to involving family members in care, which was enshrined in the Unit Philosophy, relatives were banished to the waiting room for hours. They experienced feelings of powerlessness and helplessness as they waited with other relatives for news following investigations or until 'the doctor had completed his rounds'. Explanations of "we must make 'the patient' comfortable" was no consolation for those who wished to be involved in care. The words "I'il call you when we are ready" became a mantra to the forgotten families who waited patiently for those with power to admit them to the ICU. Implications are this family felt they were left alone to cope with the traumatic expériences leading up to and surrounding the death. They felt mainly supported by the priest, who not only administered the last rites but provided spiritual support to the family and dealt sensitively with many issues. Paternalism in décision making when there is a moral obligation to ensure that discussions on end of life dilemmas are an inclusive process with families, doctors, nurses was not understood, therefore it caused conflict within the family over EOL décision making. The family felt that the opportunity to share expériences through telling and retelling their stories would enable them to reconfigure the past and create purpose in the future.

Exposure to Stressful Life Events and Lung Cancer Risk

Objectif: Examiner l’association entre l'exposition aux évènements stressants de la vie et le cancer du poumon. Méthodes: Les données proviennent d’une étude cas-témoins, menée chez les hommes et les femmes vivant dans la région métropolitaine de Montréal entre 1996 et 2001. Le cancer du poumon d’un cas éligible devait être confirmé histologiquement à l’un des 18 hôpitaux de cette région. Les témoins ont été sélectionnés aléatoirement de la liste électorale du Québec et ont été appariés au cas par fréquence de groupes d'âge et par sexe. Un questionnaire a été administré en entrevue pour recueillir les données, dont l’évaluation de huit évènements stressants de la vie par le participant. Si le participant avait vécu un évènement stressant ciblé durant les six dernières années, il devait aussi coter cet évènement sur une échelle de trois points. La régression logistique non conditionnelle a été utilisée pour estimer les rapports de cotes ainsi que leurs intervalles de confiance à 95%. Des analyses par sexe, niveau de tabagisme et par type histologique ont été réalisées. Nous avons aussi analysé l’association entre le cancer du poumon et le nombre total d'évènements, les évènements de perte et les évènements socioéconomiques, ainsi que chaque évènement individuellement. Les analyses des scores d'impact autoévalués et avec un score externe de perception, ont également été menées. Résultats: La population de ce projet comprend 1061 cas et 1422 témoins, âgés de 35 à 70 ans. Les participants inclus avaient répondu aux sections du questionnaire portant sur les facteurs de style de vie et sur l'historique de tabagisme. Dans l'ensemble, nous n’avons pas observé d’association entre le cancer du poumon et l'exposition aux évènements stressants de la vie. Nous avons observé une diminution du risque pour les évènements socioéconomiques autoévalués comme peu stressants (RC=0,50; IC 95%= 0,31 - 0,81). Conclusion: Nos résultats suggèrent que les évènements socioéconomiques sont associées à un risque réduit si ces évènements sont considérés comme peu stressant.

The influence of HIV, HCV and inhibitors on the quality of life and behavior of the disease in patients with haemophilia: An observational study

Inhibitors are the main complication in the treatment of haemophilia. A high percentage of adult patients were infected in past decades by HIV and HCV through factor concentrates. This study compared the quality of life of patients with hemophilia (QoL) and illness behavior in adult patients with haemophilia according to the development of inhibitors and HIV or HCV co-infection. This is an observational clinical study. 69 adult patients with haemophilia participated. We used A36 Hemophilia-QoL and IBQ questionnaires to measure the QoL and illness behavior, respectively. The dependent variables were type and severity of haemophilia, type of treatment, development of inhibitors, HIV and HCV infection, or both. We observed significant differences in the perception of QoL and illness behavior in patients according to the development of inhibitor and coinfection with HIV-HCV. We obtained four groups: the first and second group, which comprise 67% of the sample, exhibit behavior patterns indicating good adaptation to the disease and good QoL. The other two groups, which comprise 33% of the sample show behavior that is not well adapted to the disease, and poor quality of life. The development of inhibitors itself does not influence the quality of life and illness behavior in patients with haemophilia. Patients infected with HIV or HCV do not have a worse illness behavior compared to those uninfected. The development of inhibitors and HIV-HCV co-infection has a negative impact on quality of life and illness behavior in patients with haemophilia.

The difference of Being in the early modern world: a relational-material approach to life in Scotland in the period of the witch trials

This thesis investigates how ways of being in different ontologies emerge from material and embodied practice. This general concern is explored through the particular case study of Scotland in the period of the witch trials (the 16th and 17th centuries C.E.). The field of early modern Scottish witchcraft studies has been active and dynamic over the past 15 years but its prioritisation of what people said over what they did leaves a clear gap for a situated and relational approach focusing upon materiality. Such an approach requires a move away from the Cartesian dichotomies of modern ontology to recognise past beliefs as real to those who experienced them, coconstitutive of embodiment and of the material worlds people inhabited. In theory, method and practice, this demands a different way of exploring past worlds to avoid flattening strange data. To this end, the study incorporates narratives and ‘disruptions’ – unique engagements with Contemporary Art which facilitate understanding by enabling the temporary suspension of disbelief. The methodology is iterative, tacking between material and written sources in order to better understand the heterogeneous assemblages of early modern (counter-) witchcraft. Previously separate areas of discourse are (re-)constituted into alternative ontic categories of newly-parallel materials. New interpretations of things, places, bodies and personhoods emerge, raising questions about early modern experiences of the world. Three thematic chapters explore different sets of collaborative agencies as they entwine into new things, co-fabricating a very different world. Moving between witch trial accounts, healing wells, infant burial grounds, animals, discipline artefacts and charms, the boundaries of all prove highly permeable. People, cloth and place bleed into one another through contact; trees and water emerge as powerful agents of magical-place-making; and people and animals meet to become single, hybrid-persons spread over two bodies. Life and death consistently emerge as protracted processes with the capacity to overlap and occur simultaneously in problematic ways. The research presented in this thesis establishes a new way of looking at the nature of Being as experienced by early modern Scots. This provides a foundation for further studies, which can draw in other materials not explored here such as communion wares and metal charms. Comparison with other early modern Western societies may also prove fruitful. Furthermore, the methodology may be suitable for application to other interdisciplinary projects incorporating historical and material evidence.

Relationship between phenotype and environment in marine calcifying organisms: exploring growth and shell properties of different mollusks species in past and modern scenario

Coastal ecosystems represent an inestimable source of biodiversity, being among the most productive areas on the planet. Despite the great ecological and economic value of those environments, many threats endanger the species living in this ecosystem, like the rapid warming and the sea acidification, among many other. Benthic calcifying organisms (e.g. mollusks, corals and echinoderms) in particular, are among the most exposed to those hazards. These organisms use calcium carbonate as a structural and protective material through the biomineralization process, biologically controlled by the organism, but nevertheless, strongly influenced by the environmental surroundings. Evaluating how a changing environment can influence the process of biomineralization is critical to understand how those species of great ecological and economic importance will face the ongoing climate change. This thesis investigates the mechanism of biomineralization in different mollusks’ species of the Adriatic Sea, providing detailed descriptions of shells skeletal, biometric and growth parameters. Applying a multidisciplinary and multi-scale research approach, the influence of external environmental factors on the process of shell formation has been investigated. To achieve this purpose analysis were conducted both on current populations and on fossil remain, which allows to investigate ecological responses to past climate transitions. Mollusks’ shells in fact are one of the best tools to understand climate change in the past, present and future, since they record the environmental conditions prevailed during their life, reflected on the geochemical properties, microstructure and growth of the shell. This approach allowed to overcome the time scale limit imposed by field and laboratory survey, and better understand species long term adaptive response to changing environment, a crucial issue to define proper conservation and management strategies. Furthermore, the investigation of fossil record of mollusks assemblages offered the opportunity to evaluate the long-term biotic response to anthropogenic stressors in the north Adriatic Sea.
