Leadership is considered one of the most important factors when it comes to the experience of a well-functioning workplace and therefore there are many studies about leadership. Our study aims to examine how the experiance of a well-functioning workplace can be explained by the cohesion instead of just leadership. To study the cohesion it has been important to ensure the corporate culture that prevails. We have studied this by examine the company's standards and values, the invisible culture. The study is conducted at a company that is in the middle of a valuation process, which means that they do not have any formal values that they work for. Despite this, the employees have a common understanding of how the values of the company are ​​perceived. This is a result of a strong cohesion. The study is based on a qualitative approach where we conducted interviews with eight employees in a recruitment company in southern Sweden. We have also done simple observations when we spent a lot of time at the company's office. We have analyzed our material using three key concepts; corporate culture, autonomy and roles. These concepts also became our keywords. The results of the study shows that a good cohesion is the key to a functioning workplace. Our conclusion is that it is not only the leadership that is the foundation for a well-functioning workplace. Leadership is a contributing factor, but it is the leardership together with the employes that create a well-functioning workplace.

This paper seeks to describe and explain the social efficacy of art by addressing it as contemporary western infrastructure for social cohesion. Social cohesion refers here not to teleological status quo, but to pluralistic, yet fairly peaceful co-habitation, allowing for gradual change while preserving continuity of the group identity. Employing Actor-Network Theory, this paper views artistic practice as actor-network assemblage process making connections and vehicles that enable movement of ideas, values, visions and dissents throughout the community. Parallel memberships of the same actors in artistic and non-artistic actor-networks create conditions for artistic meanings to “bleed over” also into other spheres of the social life where they can gain efficacy far beyond the “art world”. Art infrastructure operates under particular “regime of art” that suspends some of the “real world” rules and sanctions ambiguity, facilitating less confrontational reconciliation of diverse and contradictory meanings than is customary in e.g. science, religion, politics, economy, railways, sewage or other infrastructures that also have impact on social cohesion. Debates about the definitions of “art” or particular objects’ belonging to “art” emerge in this perspective as debates on the scope of applicability of the “regime of art”, as it may have significant social consequences. By outlining an infrastructural theory of art this paper seeks to fill a theoretical gap in a rather fragmented field of anthropology of art and to propose novel ways to deploy insights from anthropological engagements with infrastructure. Empirical data of this paper come from a five weeks fieldwork in Alaska.

MA, Faculty of Humanities, University of the Witwatersrand, 2009 / Even though investigations of knowledge construction within CMC have been conducted (e.g. Gunawardena, Lowe and Anderson, 1997; Schellens & Valcke, 2004), no research has compared F2F communication and CMC in terms of the ability to solve complex tasks and to develop group cohesion. Group cohesion has been found to be vital for group cooperation and performance. Eight self-formed groups of 5 student participants each volunteered to participate in this study. Each group was required to solve two standardised, complex tasks in the same order. Student groups were randomly assigned to one of four medium combinations with two groups per combination. The combinations were: F2F communication for both tasks, CMC for both tasks, F2F communication for the first task and CMC for the second task, and CMC for the first task and F2F communication for the second task. Measures of knowledge construction were taken using the IAM (Gunawardena et al., 1997), group cohesion (assessed before and after the tasks) using the GAS (Evans & Jarvis, 1986), and a self-developed scale to assess satisfaction with the process and the outcome. The results showed that CMC groups produced significantly fewer contributions, and took a longer time to complete tasks, but there was no significant difference between the two mediums in terms of knowledge construction. The medium combination of F2F communication followed by CMC, achieved the least time to completion; the second most effective medium for knowledge construction, the greatest satisfaction with respect to group processes and the decision in the first task, and achieved a significantly higher level of post-manipulation group cohesion.

Thesis advisor: James E. Lubben / This study examined the roles cohesion, coping, and perceived threat have in buffering the effect of war-zone stress on mental health symptoms. Specifically, six factors were tested as potential moderators of the relationship between combat-related stressors and posttraumatic stress symptomatology (PTSS), including horizontal (peer) cohesion, vertical (NCO) cohesion, vertical (officer) cohesion, problem-focused coping, emotion-focused coping, and perceived threat. In addition, direct effects and curvilinear interaction effects were examined. This study was a secondary analysis of Mental Health Advisory Team (MHAT) VI data collected by military researchers as part of an ongoing effort to assess soldiers' behavioral health. This study analyzed data from a total of 1,824 male and female U.S. Army soldiers from 15 active-duty brigades who anonymously completed the Walter Reed Army Institute of Research (WRAIR) Deployment Well-Being Survey during their deployment to Iraq in support of Operation Iraqi Freedom (OIF). PTSS, combat-related stressors, horizontal (peer) cohesion, vertical (NCO) cohesion, vertical (officer) cohesion, problem-focused coping, emotion-focused coping, and perceived threat were measured. Hierarchical multiple regression analysis was used to identify both risk factors and protective factors for PTSS. The analysis revealed three risk factors and four protective factors. During a war-zone deployment, higher levels of combat-related stressors, problem-focused coping, and perceived threat (i.e., risk factors) were independently associated with greater report of PTSS. Higher levels of horizontal (peer) cohesion, vertical (NCO) cohesion, vertical (officer) cohesion, and emotion-focused coping (i.e., protective factors) were independently associated with decreased levels of PTSS. Hierarchical moderated multiple regression analysis indicated that vertical (NCO) cohesion, vertical (officer) cohesion, and emotion-focused coping buffered the effect of combat-related stressors on PTSS; soldiers higher in vertical (NCO) cohesion, vertical (officer) cohesion, and emotion-focused coping showed weaker relationships between combat-related stressors and PTSS. No support for curvilinear interaction effects were found, suggesting that for this population of soldiers deployed to Iraq, the moderating effect of vertical cohesion and emotion-focused coping on the relationship between combat-related stressors and PTSS is linear in nature. / Thesis (PhD) — Boston College, 2012. / Submitted to: Boston College.

The purpose of the present research programme was to inform the development and subsequent delivery of an intervention to enhance interpersonal emotion regulation. Although emotion regulation has been emphasised due to its importance in explaining performance and well-being, the focus of research has predominantly been on intrapersonal emotion regulation. The present study addressed the dual-gap in research by extending research in interpersonal emotion regulation in general and developing and testing theory-led interventions for use in sport. A three-stage programme of research was set up with stage one reviewing the extant literature before proposing a social-functional approach to emotions, and in particular the Emotions As Social Information (EASI) model, as possible theoretical frameworks for use in sport. Qualitative methods were emphasised as these are particularly useful in studies seeking to identify mechanisms underlying the effectiveness of interventions. Stage two began with a narrative analysis to outline the potential social functions and consequences of emotional expressions, verbalisations, and actions in ice hockey. Two ice hockey players, each captain of their respective team, participated in semi-structured interviews. Participants described how emotions informed them of important circumstances in their environment that required attention and prepared them for such challenges at the individual level. At a dyadic level, emotions helped participants understand the emotional states and intentions of their teammates contributing toward an assessment of the extent to which they were prepared to face their challenges. At a group level, emotions helped participants lead their teammates in meeting team goals. Finally, at the cultural level, emotions helped participants maintain culture-related identities. Stage two continued with examining the processes, strategies used, and potential moderating factors in interpersonal emotion regulation among 16 ice hockey players from an English professional league. An inductive and deductive analysis revealed 22 distinct strategies used to regulate teammates' emotions. These were distinguished between strategies that were verbal or behavioural in nature. They were further distinguished between strategies employed to initiate interpersonal emotion regulation through affective and cognitive channels. Moderating factors in the interpersonal emotion regulation process were consistent with the EASI model. Stage three involved the development, delivery and assessment of the intervention. A British ice hockey team was recruited and the intervention was delivered over the course of three competitive seasons. The primary intervention goal was to improve interpersonal emotion regulation as evidenced by being able to accurately identify when an emotion regulation strategy was needed, and select and use a strategy that changed emotions in the direction and strength intended (Webb, Miles, & Sheeran, 2012). Given the link between emotion and performance, it was expected that the intervention would bring about improvements in individual and team performance. Techniques to bring about change comprised of brief contact interventions, dressing room debriefs, feedback from emotional intelligence assessments, and the practitioner managing himself as an intervention tool. The merit of the intervention was judged through practitioner reflections, social validity assessments, pre- and post-intervention measures of emotional intelligence and performance. Collectively, the present research programme contributes to the emotion regulation literature not only in sport, but also in psychology in general. A key achievement of the programme has been the development of a theoretically sound but ecologically valid intervention designed to improve the interpersonal emotion regulation skills of athletes. Although the intervention primarily catered to the needs of the current team and utilised the professional philosophy of the researcher-practitioner, the intervention provides support for enhanced performance derived from theory explaining a social-functional account of emotions. Future research might use the theory and approach to testing the theory in different sports to examine the role of each sport sub-culture on interpersonal emotion regulation.

From initial contact with water until hardening, and deterioration, cement and concrete materials are subjected to various chemical and physical transformations and environmental impacts. This thesis focuses on the properties during the fresh state, shortly after mixing until the induction period. During this period flow history, including shearing and resting, and hydration both play big roles in determining the rheological properties. The rheological properties of cement and concrete not only affect the casting and pumping process, but also very critical for harden properties and durability properties. Compared with conventional concrete, self-consolidating concrete (SCC) can introduce many advantages in construction application. These include readiness to apply, decreasing labor necessary for casting, and enhancing hardened properties. However, challenges still remain, such as issues relating to formwork pressure [1-7] and multi-layer casting [8]. Each of these issues is closely related to the property of thixotropy. From the microstructural point of view, thixotropy is described as structural buildup (flocculation) under rest and breakdown (deflocculation) under flow. For SCC, as well as other concrete systems, it is about balancing sufficient flowability during casting and rate of structural buildup after placement for the application at hand. For instance, relating to the issue of SCC formwork, it is ideal for the material to be highly flowable to achieve rapid casting, but then exhibit high rate of structural buildup to reduce formwork pressure. This can reduce the cost of formwork and reduce the risk of formwork failure. It is apparent that accurately quantifying the two aspects of thixotropy, i.e. structuration and destructuration, is key to tackling these challenges in field application. Thus, the overall objective of my doctoral study is to improve quantification of key parameters tied to thixotropy that we have identified to be important: static yield stress, cohesion and degree of shear-induced particle migration. The two main contributions are as follows: Firstly, I quantified structuration of fresh paste and mortar systems by measuring static yield stress. After an extensive review of various rheological methods to probe viscoelastic properties of yield stress fluids, I selected, developed, and implemented a creep recovery protocol. Creep results were supplemented by low-amplitude oscillatory shear results, and supported that the measured static yield stress corresponds to the solid-liquid transition. This improved quantification of static yield stress can help better understand the effect of mix composition on SCC formwork pressure development, as well as static segregation and stability [9]. Since the static yield stress is measured before the structure is broken down, the effects of sand migration are eliminated. This study also analyzed effects of other supplementary cementitous materials such as nanoclay and fly ash. Results showed that nanoclay effectively increases static yield stress and structuration rate, while fly ash decreases static yield stress. To complement this investigation, I studied cohesion using the probe tack test, as cohesion is widely cited to be closely related to formwork pressure. I verified that probe tack test is a quick and useful method to measure static cohesion. Results showed that nanoclay increased cohesion dramatically while fly ash did not have an apparent effect on cohesion. Secondly, I developed an empirical model to fit the stress decay process under constant shear rate, For mortar systems, the stress decay can be attributed to two mechanisms: colloidal destructuration and sand migration. Such a model could be used to characterize particle migration and dynamic segregation [10], a critical issue for casting applications. In addition, shear induced particle migration is a widely recognized challenge in characterizing mortars and concretes through shear rheological methods [11-13]. Therefore this model can help determine the range of shear rates within which migration can be minimized to guide the design of protocols for dynamic rheological characterization and to ultimately develop design strategies to minimize mitigation. Compared with currently existing methods, this model provides a faster approach to quantify the sand migration process, including kinetics.

The group of people aged 85 years and older is the fastest growing chronological population on the United States (Neal et al., 1993), and while a considerable amount of research has focused on the language of the elderly (those over 65 years), relatively little study has focused specifically on those aged 85 and older. This study is valuable in that it includes a large sample of optimally healthy people aged 85 and older. This sample of the optimally-healthy oldest-old will help define what changes, if any, are a function of age alone and what changes are clinical (associated with some disease, neurologic complication, or psychological impairment). The purpose of this study was to compare two groups of elderly people's use of cohesion during an expository discourse task. This study also sought to answer the following question: If no health problems exist, does age alone affect the cohesion in the expository discourse of the elderly? To effect this comparison, a comparison of cohesive use in a group of 12 people between the ages of 65 and 75 years (the young-old) was contrasted with cohesion used by a group of 27 people aged 85 years and older (the oldest-old). The subjects were gathered as part of the Oregon Brain Aging Study under the direction of doctors Diane Howieson and Jeffrey Kaye of the Portland VA Medical Center. The subjects had to meet strict inclusion and exclusion criteria. As part of the evaluations for the Oregon Brain Aging Study, each subject was audiotaped while describing the fishing picture from the Neurobehavioral Cognitive Inventory (Kiernan et al., 1987). Each sample was then transcribed, divided into T-Units, and analyzed according to the cohesive analysis designed by Liles (1985) and Liles et al. (1989). Group comparisons for each aspect of cohesion (frequency, style, and adequacy) was completed using a 1- test. No significant differences at the .05 level were found on any of the measures.

Scientists have been well aware of the complexity of Martian and lunar regoliths. There are vast unexplored areas on both, the Moon and Mars, as well as uncertainties in our understanding of the physicochemical properties of their regoliths. Lunar and Martian regoliths differ from terrestrial soils in that they appear granular, but are expected to contain some cohesion. As such, cohesion in regolith poses challenges for future space operations, more specifically for landing, settlement, and mobility purposes. The ability to induce prescribed levels of cohesion in regolith simulants and reliably measure it would allow scientists to evaluate space technology limitations under different operational scenarios on Earth prior to a mission. Therefore, the objectives of this research were to (1) develop methods to induce prescribed levels of cohesion in dry granular media, and (2) evaluate accessible and reliable testing methods to measure cohesion. We developed and evaluated several methods to induce cohesion in two types of dry sand, F-75 silica sand and generic play sand. The methods to induce cohesion included play sand mixed with sugar-water, polymeric sand, and nanocellulose fibers, as well as F-75 sand mixed with polydimethylsiloxane, polyvinyl acetate, crystalline silica, agar, zero-valent iron, adhesive spray, and sand surface modification using a plasma gun. Each method was assessed for advantages and disadvantages, and laboratory specimens produced using the most promising methods were tested at different compositions and densities to measure cohesion. The laboratory methods used to measure the cohesion included direct shear test, simple direct shear test, and vertical cut test. The results from these tests were then compared to tensile strength tests, using a split box test. In addition, these tests were also performed on lunar simulants JSC-1A and GRC-3 at different densities. The direct shear apparatus was available, but the other three devices were fabricated as part of this work. Based on the research results, simple methods to potentially induce low levels of cohesion in dry granular media are suggested along with suitability of laboratory methods to measure the added cohesion.

Organizations attempting to optimize productivity are seeking new ways to develop psychological capital in teams. The researcher conducted a quantitative study to determine whether team cohesion, as assessed by the Revised Group Environment Questionnaire (RGEQ), impacts team productivity, as assessed by the Performance Measurement Team (PMT) Manufacturing Resource System (MRS); whether this relationship can be attributed to a team's level of psychological capital, as assessed by the Psychological Capital Questionnaire (PCQ-12); and whether psychological capital mediates the relationship between team cohesion and team productivity. Forty-five PMTs in a large U.S. defense manufacturing organization were surveyed using the PCQ-12 and the RGEQ, and their respective PMT MRS productivity levels were recorded. Barron and Kenny's 4-step mediation analysis was employed using simple and multiple regression to determine whether a team's level of cohesion significantly contributes to its productivity and if its level of psychological capital mediates the relationship between cohesion and productivity. The results indicated that team cohesion does not predict team productivity and that psychological capital is not a mediator of team cohesion and productivity. Although cohesion and psychological capital have a significant positive effect on supervisor performance ratings, the effect is diminished when viewing the objective measure of productivity. The study promotes positive social change in the workplace by elevating awareness of the effect of team cohesion on the psychological states of manufacturing workers. Understanding these relationships will help organizations to implement teaming methods that support the efficiencies and well-being of employees.

A team's performance in any sport can be predicted by many factors. Some of these factors include team collective efficacy, team cohesiveness, and coaching competency. Currently, there is little research investigating the relationships among teams' beliefs about their capabilities, their level of cohesion, and their perceptions of coaching competency on overall sport performance. The purpose of this study was to document the relationship among collective efficacy, cohesion, and coaching on sport performance in a sample of university athletes. The objectives of this study were to identify the level of cohesion, collective efficacy, and perceptions of coaching competency by each athletic team at the university, and to identify the relationships among each of these variables in regard to sport performance. Participants were 163 collegiate athletes involved in eight sports at Utah State University during the 2005-2006 academic year. Correlational analysis revealed significant positive relationships with collective efficacy, cohesion, and coaching competency. Multi-level modeling and linear regression analyses revealed that collective efficacy was a significant predictor of win/loss percentage, whereas some aspects of cohesion and coaching competency were seen as predictors of collective efficacy.
