Institutional safe space and shame management in workplace bullying

Shin, Hwayeon Helene, helene.shin@abs.gov.au January 2006 (has links)
This study addresses the question of how an individual’s perception of the safety of his or her institutional space impacts on shame management skills. Shame has been widely recognised as a core emotion that can readily take the form of anger and violence in interpersonal relationships if it is unresolved. When shame is not acknowledged properly, feelings of shame build up and lead to shame-rage spirals that break down social bonds between people. Some might consider the total avoidance of shame experiences as a way to cut the link between shame and violence. However, there is a reason why we cannot just discard the experience of shame. Shame is a self-regulatory emotion (Braithwaite, 1989, 2002; Ahmed et al., 2001). If one feels shame over wrongdoing, one is less likely to re-offend in the future. That is to say, shame is a destructive emotion on the one hand in the way it can destroy our social bonds, but on the other hand, it is a moral emotion that reflects capacity to regulate each other and ourselves. This paradoxical nature of shame gives rise to the necessity of managing shame in a socially adaptive way. A group of scholars in the field of shame has argued that institutions can be designed in such a way that they create safe space that allows people to feel shame and manage shame without its adverse consequences (Ahmed et al., 2001). This means that people would feel safe to acknowledge shame and accept the consequences of their actions without fear of stigmatisation or the disruption of social bonds. Without fear, there would be less likelihood of displacing shame, that is, blaming others and expressing shame as anger towards others. The context adopted for empirically examining shame management in this study is workplace bullying. Bullying has become a dangerous phenomenon in our workplace that imposes significant costs on employers, employees, their families and industries as a whole (Einarsen et al., 2003a). Teachers belong to a professional group that is reputed to be seriously affected by bullying at work. Teachers from Australia and Korea completed self-report questionnaires anonymously. Three shame management styles were identified: shame acknowledgement, shame displacement and (shame) withdrawal. The likely strengths of these shame management styles were investigated in terms of three factors postulated as contributions to institutional safe space: that is, 1) cultural value orientations, 2) the salience of workgroup identity, and 3) problem resolution practices at work. The present thesis suggests that further consideration should be given to institutional interventions that support and maintain institutional safe space and that encourage shame acknowledgement, while dampening the adverse effect of defensive shame management. The evidence presented in this thesis is a first step in demonstrating that institutional safe space and shame management skills are empirically measurable, are relevant in other cultural contexts and address issues that are at the heart of the human condition everywhere........

The ecological significance of sexual reproduction in peat mosses (Sphagnum)

Sundberg, Sebastian January 2000 (has links)
<p>Peat mosses (<i>Sphagnum</i>) are widely distributed and are a major component of mire vegetation and peat throughout the boreal and temperate regions.

The Possibility Of Financial Crises In Developing Countries Under Flexible Exchange Rate Regimes: A Multidimensional Approach

Colak, Mehmet Selman 01 September 2012 (has links) (PDF)
Many economists and politicians have blamed fixed exchange rate regimes for several crises taking place in developing countries after the 1980s. According to them, since the beginning of the 2000s, widespread implementation of flexible exchange rate regimes and high international reserves have prevented developing countries from experiencing similar catastrophic experiences. This interpretation seems to be misleading. We believe that even flexible exchange rate regimes with high international reserves do not have a magic to prevent a financial crisis. Although flexible exchange rate regimes and high international reserves might have played some positive roles in the relatively calm period of 2001-2008 / the main reason behind the calmness of this period is the fact that developing countries did not face a strong financial shock during this period. In the presence of &ldquo / safe havens&rdquo / , which implies existence of safe developed countries for financial capital to move into, flexible exchange rate regimes and the accumulated large reserves may not be adequate when a wave of financial shocks, as in the form of sudden stops and capital reversals, hit developing countries. Indeed, the absence of safe heavens and very low yields in developed countries eased the pressure on developing countries during the recent financial crisis of 2008-2009. If developed economies get their safe haven status back, developing countries might face new financial shocks. In this sense developing countries would experience new financial crises in this new period. We will elaborate on the possible conditions of these prospective financial crises in this thesis.

Evaluation of the Compartment Bag Test for the Detection of Escherichia coli in Drinking Water

Miller, Candace D 17 May 2013 (has links)
INTRODUCTION: More than 1.8 million diarrheal disease deaths can be attributed to the lack of access to water, sanitation and hygiene. These deaths occur mostly in developing countries where water quality testing resources are limited. Several tests are currently used to detect and quantify E. coli and other fecal coliforms in drinking water, however they can be expensive, complex, and technically demanding. There is a need for a simple, reliable, low-cost water quality test that can be used in resource limited settings. Therefore, the purpose of this research was to perform a rigorous evaluation of the recently developed compartment bag test for detection and quantification of E. coli against the standard method, membrane filtration. METHODS AND RESULTS: A total of 270 water samples were collected from forty-five various naturally contaminated water sources around metro-Atlanta from August 2011 through April 2012 and processed using the compartment bag test and membrane filtration with mI agar. Concentrations of E. coli were significantly correlated with a correlation coefficient of 0.904 (95% CI 0.859 – 0.950). Sensitivity and specificity were 94.9% and 96.6%, respectively. CONCLUSION: These results suggest that the compartment bag test produces results consistent with those produced by membrane filtration on mI agar. Based upon its performance, the compartment bag test has the potential to be used as a reliable, low-cost drinking water quality test globally where water quality testing resources are not readily available, and can be implemented in monitoring activities for microbial water quality.

The Good Cut: The Barbershop in the African American Literary Tradition

Bozeman, Terry Sinclair 28 May 2009 (has links)
Few African American males do not have at least one memory of a barbershop. The barbershop is a space that finds a home in virtually every community in which you find Black males. To some degree, virtually all genres and periods of African American literary expression have situated the barbershop as a mediating space in the formulation of a Black masculine identity. The barbershop as mediating space allows Black males the opportunity to view themselves and also critique the ways in which they are gazed upon by the literary imagination. African American authors, through the use of the barbershop, bring to the center the construction of this space in Black masculinity identity formation. ¬ Although a common presence in African American literature, the barbershop has not received any serious, i.e. book length examinations in literary analysis. I argue that the historical portrayal of the barbershop as mediating space problematizes the intersections of ancestor, culture, history, memory and literary imagination to reveal the intricate relationship between Black males and the space. I seek to address the gap in coverage of the literary treatment of the African American barbershop as mediating structure in the formulation of a black masculine identity. My research will show that we cannot fully understand the literary formation of Black masculine identity unless we attend to the barbershop as a formative mediating space.

Trygghet i staden : Finns det samband mellan människors upplevda trygghet och polispatrullering?

Pettersson, Sandra, Zakó, Elin January 2013 (has links)
Kan polisnärvaro skapa trygghetskänslor hos människor? Studien har undersökt förhållandet mellan människors upplevda trygghet och tre olika typer av polispatrullering i en relativt trygg och relativt otrygg stadsmiljö. För att besvara frågeställningarna genomfördes en enkätundersökning där respondenterna, 112 män och 131 kvinnor (M=30 år, SD=12.98), fick skatta sin upplevda trygghet utifrån bilder med de tre olika typerna av polispatrullering. Resultatet indikerade att alla typer av polisnärvaro ingett trygghet i den relativt otrygga stadsmiljön. Polispatrullering till fots frambringade mer trygghetskänslor än polisbilspatrullering. Resultaten var giltiga för både män och kvinnor. Slutsatsen är att polisnärvaro kan inge trygghet i relativt otrygga stadsmiljöer men i relativt trygga stadmiljöer är inte någon av de tre undersökta typerna av polispatrullering effektiva. / Can police presence make people feel safe? This study explored the relationship between people’s experience of feeling safe and three different kinds of police patrolling in a relatively safe and a relatively unsafe urban area. A survey was distributed, 112 men and 131 women (M=30 years, SD=12.98), to estimate the perception of feeling safe by looking at photos with three different kinds of police patrolling. The result indicated that all kinds of police patrolling had positive effect on the respondent’s feelings of safety in the relatively unsafe urban area. Police foot patrol tended to increase the respondents feelings of safety more than police patrolling by car. Similar results were found for both men and women. Police presence may increase people’s feelings of safety in relatively unsafe urban areas, but in relatively safe urban areas none of the three types of police patrol were effective.

Wang, Hong-ping 10 April 2006 (has links)
The military threat of the Soviets disappears, the communist China should meeting general matter reorganization power deceleration But, by in recent years national defense budget to see, but keep on significant the growth of the degree with every year. Understand manifestation the communist china sets up the soldier reorganization actively, accelerating national defense reformation. Therefore, intention that the Communist china national defense reform also is the research motive of the thesis where. The research point of this thesis, post cold war the national defense strategy of period communist china develops after keeping on the understand, and try the main content of tidying up the national defense reformation, detailed study to the current conditions and developments of the Liberation Arming military strength particularly, furthermore further analyze to the pacific Asia region, influence of security Taiwan strait, then put forward the suggestion toward my country national defense construction. Study through this thesis. can find, the communist china is outside safeguard national security benefit and the war of Persian gulf etc. inside under factor influence, concentrate on the construction of developing the high technique limited war and consociation battle. The special features that is among them is as follows first: fast reaction troops .two establishments of the cannon troopses , make the communist china have the offensive and limited nuclear of the limited war to shoot the ability. Second promote the sea, air force¡¦s position, emphasize maritime power, system the importance of the empty power. Third promote the military thought of the information war, dissymmetry battle, strengthen the information war power. Forth value national defense science and technology self-made ability, weapon buys outside and the military communicates. Fifth emphasize special kind the soldier grows of construction. Meanwhile, the national defense reformation that the communist china carry on will threaten to the formation military of neighboring nation in pacific Asia region, as a result must make the communist china promote the new national security view, to avoid to sink into the security dilemma, then become big country in World.

Investigation Of Waterhammer Problems In Camlidere Dam - Ivedik Water Treatment Plant Pipeline At Various Hydraulic Conditions

Sakabas, Emre 01 February 2012 (has links) (PDF)
&Ccedil / amlidere Dam supplies significant portion of the potable water demand of the City of Ankara. Consequently, it is very important that the pipelines extending over 60 km between the dam and the treatment plant at Ivedik operate continuously. At present, two composite parallel lines are in operation and construction of a third line is considered for the future. It is the aim of this study to investigate the water hammer problems to be expected under various scenarios and also suggest the safe operation conditions for the system. Water hammer analyses of the pipeline are carried out by computer software named HAMMER. This software employs the Method of Characteristics (MoC) which is a widely used mathematical procedure in solving the non-linear differential equations caused by unsteady flow. Within this theses work, existing tunnels, prestressed concrete and steel pipes, third steel pipeline which is planned to be constructed in the future and existing, and future-planned valves are modeled and calibration of the model is implemented. A plenty of scenarios and valve closure principles are constituted in order to specify steady-state conditions and additional water hammer pressures generated by several excitations through the pipeline. Results of these scenarios are compared with previous works conducted on the pipeline system and the most unfavorable ones among those are determined. Then, appropriate closure durations are identified and suggested for pipe fracture safety valves and the flow control valves at Ivedik in order not to cause excessive pressures in the system.
