Description
Using experience, observations, data, current research, and writings in the field of volunteer management, it was determined there was a need to study the effects of leadership/management practices on the productivity outcomes of a volunteer construction workforce. A simple wood bench that would be tiled and painted was designed to test the areas of Time, Waste, Quality, Safety, and Satisfaction of different volunteer groups. The challenge was bolstered by giving the teams no power tools and limited available resources. A simple design of experiment model was used to test highs and lows in the three management techniques of Instruction, Help, and Encouragement. Each scenario was tested multiple times. Data was collected, normalized and analyzed using statistical analysis software. A few significant findings were discovered. The first; the research showed that there was no significant correlation between the management practices of the leader and the satisfaction of the volunteers. The second; the research also showed when further analyzed into specific realistic scenarios that the organizations would be better to focus on high amounts of Help and Encouragement in order to maximize the productivity of their volunteer construction workforce. This is significant as it allows NPO's and governments to focus their attention where best suited to produce results. The results were shared and the study was further validated as "significant" by conducting interviews with experts in the construction nonprofit sector.

Description
This dissertation is an exploratory study that examined the differences in perceptions about supply chain management strategy, topics, tools, and techniques between procurement professionals in public and private sector organizations. This was accomplished through a survey of procurement professionals in a Fortune 500 company and a municipality in Arizona. The data were analyzed to understand how perceptions of supply chain management differed within this sample and whether the differences in perceptions were associated with formal education levels. Key findings indicate that for this or similar samples, public procurement respondents viewed their organizations' approach to supply chain management as a narrow function within purchasing while private sector respondents viewed their organization's approach to supply chain management as a strategic purchasing perspective that requires the coordination of cross functional areas. Second, public procurement respondents reported consistent and statistically significant lower levels of formal education than private sector respondents. Third, the supply chain management topics, tools, and techniques seem to be more important to private sector respondents than the public sector respondents. Finally, Respondents in both sectors recognize the importance of ethics and ethical behavior as an essential part of supply chain management.

Description
The construction industry in India suffers from major time and cost overruns. Data from government and industry reports suggest that projects suffer from 20 to 25 percent time and cost overruns. Waste of resources has been identified as a major source of inefficiency. Despite a substantial increase in the past few years, demand for professionals and contractors still exceeds supply by a large margin. The traditional methods adopted in the Indian construction industry may not suffice the needs of this dynamic environment, as they have produced large inefficiencies. Innovative ways of procurement and project management can satisfy the needs aspired to as well as bring added value. The problems faced by the Indian construction industry are very similar to those faced by other developing countries. The objective of this paper is to discuss and analyze the economic concerns, inefficiencies and investigate a model that both explains the Indian construction industry structure and provides a framework to improve efficiencies. The Best Value (BV) model is examined as an approach to be adopted in lieu of the traditional approach. This could result in efficient construction projects by minimizing cost overruns and delays, which until now have been a rarity.

Description
After decades of dormancy, character is re-emerging as an important research topic among organizational leadership researchers in response to the need to better explain the source of certain exemplary and ethical leader performance (Hannah & Avolio, 2011; Leonard, 1997; Thompson & Riggio, 2010; Wright & Goodstein, 2007). However, efforts to operationalize character are criticized for their abstract and idealistic trait-based conceptualizations that fail to capture the reality of leadership and situational dynamics (Conger & Hollenbeck, 2010). The purpose of this study is to develop a more robust theoretical approach to character that is empirically grounded in the real life complexities of leadership. Combat provides the context for this study because the adversity of such an extreme context tends to make character a more salient and readily observable phenomenon than in more conventional organizational contexts (Wright & Quick, 2011; Hannah, Uhl-Bien, Avolio, & Cavarretta, 2009). I employed an ethnographic grounded theory design to gain a unique insider's perspective absent in many studies of leader character (Charmaz, 2009; Parry & Meindl, 2002). Data collection involved (1) physically embedding for six months with U.S. Army small unit infantry leaders operating in combat in Afghanistan; (2) participant observation in the full range of combat activities engaged in by these leaders; and (3) in-depth semi-structured interviews with key informants. An important contribution of this study is that the emergent concept of leader character is fully situated in the leader's social and environmental context represented by the leader's inner struggle to resist the adversity of combat and uphold the standards of leadership. In this dialectical framework, certain agentic resources important to resolving this inner struggle emerge as the locus of leader character. This agency-based concept of character is rooted in the internalization of the standards of leadership through identity-conferring normative commitments and entails particular motivational and volitional capacities. These produce a distinct mode of functioning--a strong form of personal moral agency--characterized by the leader's willingness to sacrifice in upholding standards in the face of adversity. This primacy of leader agency over adversity is the hallmark of leader character--what I call the character to lead.

Description
Bully victimization has been associated with blunted cardiovascular responses to stress as well as elevated responses to stress. The difference between these altered physiological responses to stress is largely unknown. This study explored several possible moderators to the relationship between chronic stress and future cardiac output (an indicator of increased stress) in response to future stressors. These moderators include the difference between social and physical stressors and individual levels of loneliness. Participants were administered measures of loneliness and victimization history, and led to anticipate either a "social" (recorded speech) or "non-social" (pain tolerance test ) stressor, neither of which occurred. EKG and impedance cardiography were measured throughout the session. When anticipating both stressors, loneliness and victimization were associated with increased CO. A regression revealed a three-way interaction, with change in cardiac output depending on victimization history, loneliness, and condition in the physical stressor condition. Loneliness magnified the CO output levels of non-bullied individuals when facing a physical stressor. These results suggest that non- bullied participants high in loneliness are more stressed out when facing stressors, particularly stressors that are physically threatening in nature.

Description
The healthcare system is plagued with increasing cost and poor quality outcomes. A major contributing factor for these issues is that outdated leadership practices, such as leader-centricity, linear thinking, and poor readiness for innovation, are being used in healthcare organizations. Through a qualitative case study analysis of innovation implementation, a new framework of leadership was uncovered. This framework presented new characteristics of leaders that led to the successful implementation of an innovation. Characteristics uncovered included boundary spanning, risk taking, visioning, leveraging opportunity, adaptation, coordination of information flow, and facilitation. These characteristics describe how leaders throughout the system were able to influence information flow, relationships, connections, and organizational context to implement innovation.

Description
In many respects, the current public child welfare system closely resembles that of over 100 years ago. Then, as well as now, nonprofit child welfare agencies are the critical providers of service delivery to vulnerable children and their families. Contemporary nonprofits, however, are confronted with social and fiscal pressures to conform to normative practices and behaviors of governmental and for-profit organizations. Simultaneously, these agencies may also feel compelled to behave in accordance with a nonprofit normative ethic. Yet, scholars and practitioners are often unaware of how these different forces may be shaping the practices of child welfare agencies and, the nonprofit sector in general. This multi-paper dissertation examines how managerial and organizational practices of child welfare nonprofits are influenced business, government, and other nonprofit organizations and the extent to which processes process of institutional isomorphism in child welfare nonprofits are happening. Data was collected from a national ample of 184 child welfare administrators to explore marketization practices, collaboration behaviors, and managerial priorities of these agencies. Multinomial logistic, ordered logistic, and ordinary least squares regression, and historical analysis help shed light on the contemporary practices of these agencies. The results reveal that these agency's behaviors are shaped by government control, influences from the business community, identification with a nonprofit mindset (i.e., nonprofitness), funding streams, and various other factors. One key finding is that identification with a nonprofit mindset encourages certain behaviors like collaboration with other nonprofits and placing greater importance on key managerial priorities, but it does not reduce the likelihood of adopting business management strategies. Another important finding is that government control and funding does not have as strong as an influence on child welfare nonprofits as expected; however, influence from the business community does strongly affect many of their practices. The implications of these findings are discussed for child welfare agencies and the nonprofit sector in general. The consequences of nonprofits operating similarly to business and government are considered.

Description
In my dissertation, I develop a theoretical model that explains how leaders' daily work demands and recovery affect their leadership behaviors. In a departure from the trait approach of leadership which suggests that leaders tend to behave in certain ways that are determined by their heritable characteristics such as personality and intelligence (e.g., Bono & Judge, 2002), and from the contingency approach that suggests leaders behave in ways that are most suitable to the situation based on the needs of followers and the demands of their tasks (e.g., House, 1971), this dissertation draws from the transactional theory of stress (Lazarus & Folkman, 1984) and positions the stressful demands that leaders experience at work as important determinants of their leadership behaviors. Specifically, I propose that leaders' daily challenge demands (e.g., workload, time pressure, responsibilities) are positively related to job engagement whereas their daily hindrance demands (e.g., role ambiguity, office politics, and hassles) are negatively related to engagement. Engagement, in turn, is positively related to transformational and transactional leadership and negatively related to laissez-faire leadership and abusive supervision. Meanwhile, both challenge and hindrance demands are positively related to strain, which is negatively related to transformational and transactional leadership, and is positively related to laissez-faire leadership and abusive supervision. In addition, leaders' daily after-work recovery experience influences the mediating roles of engagement and strain in the relationships between work demands and leadership behaviors. Specifically, daily recovery moderates both the first stage (i.e., the linkages between work demands and engagement and strain) and the second stage (i.e., the linkages between engagement and strain and leadership behaviors) of the mediation. I test this two-level dual-stage moderated mediation model using a two-week experience sampling design. The sample consists of 26 supervisors and 73 employees who directly report to these supervisors from the flood control district of a metropolitan county in the Southwest United States. Results suggest that leaders' daily challenge demands have a positive influence on transformational leadership attributable to engagement, a negative influence on abusive supervision attributable to engagement, and a positive influence on abusive supervision attributable to strain. Leaders' daily hindrance demands, in contrast, have a positive influence on abusive supervision attributable to strain. In addition, leaders' daily recovery moderates the relationship between strain and laissez-faire leadership so that hindrance demands have a positive influence on laissez-faire leadership when the individual is poorly recovered. Leaders' daily recovery also moderates the relationship between strain and abusive supervision so that hindrance demands have a stronger positive influence on abusive supervision through strain when the individual is poorly recovered.

Description
Purpose: This study examines the role of social support on adjustment to widowhood. Past research has indicated that the role of social support on adjustment to widowhood remains inconclusive, and needs further examination. This study examines the varying coping trajectories of middle-aged and retired bereaved spouses. Additionally, this study examines how bereavement stage may also influence one's adaptation to widowhood. Methods: This study used in-depth and semi-structured interviews as a means of understanding the role of social support on adjustment to widowhood. Participants were recruited through two hospice services available in a major metropolitan area in the United States. Convenient and purposive samplings are used in this study; this study will execute a grounded theory approach in order to determine the inconclusive role of social support on adjustment to widowhood. This study is contrasting between two stages- life course stages (middle aged versus retirement aged people) and bereavement stages (a year or less time following the death of a spouse versus three or more years following the death of a spouse). As a means of reducing bias and subjectivity, all data collected during the interview will be transcribed immediately. Results: Middle-aged bereaved spouses reported higher levels of motivation for adjusting positively and quickly towards widowhood due to their concern for protecting the well-being of their surviving young children compared to retired bereaved spouses. Differences between middle-aged widows and widowers have been found in this study; middle-aged widowers have a higher linkage to negative health behaviors. Retired bereaved spouses may fare better depending upon their housing location. Living in a retirement center may lower negative effects of bereavement on retired spouses' health. Conclusions: Types of social support received and expected varied between middle-aged widows and widowers. Gender norms may influence the type of social support widows and widowers receive. Middle-aged widowers are less likely to receive emotional support which may explain their higher linkage to negative health behaviors. Bereavement stage and housing location may be the key factors that influence widowhood trajectories of retired bereaved spouses. Living in a retirement center may lower the negative effects of bereavement on overall health.

Description
Research has demonstrated that temperature and relative humidity substantially influence overall perceptions of indoor air quality (Fang, Clausen, & Fanger, 1998). This finding places temperature quality as a high priority, especially for vulnerable adults over 60. Temperature extremes and fluctuation, as well as the perception of those conditions, affect physical performance, thermal comfort and health of older adults (Chatonnet & Cabanac, 1965, pp. 185-6; Fumiharu, Watanabe, Park, Shephard, & Aoyagi, 2005; Heijs & Stringer, 1988). The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the International Organization for Standardization (ISO) have developed thermal-comfort standards for working-age, healthy individuals. None of these standards address the physiological and psychological needs of older adults (ASHRAE Standard 55, 2010; ISO-7730, 2005). This dissertation investigates the impacts of thermal conditions on self-reported health and perceived comfort for older adults, hypothesizing that warmer and more-table indoor thermal conditions will increase the health and perceived comfort of these adults. To this end, a new set of thermal comfort metrics was designed and tested to address the thermal preferences of older adults. The SENIOR COMFORT Metrics 2013 outlined new thresholds for optimal indoor high and low temperatures and set limits on thermal variability over time based on the ASHRAE-55 2010 model. This study was conducted at Sunnyslope Manor, a multi-unit, public-housing complex in the North Phoenix. Nearly 60% (76 of 118) of the residents (aged 62-82) were interviewed using a 110-question, self-reporting survey in 73 apartment units. A total of 40 questions and 20 sub-questions addressing perceptions of comfort, pain, sleep patterns, injuries, and mood were extracted from this larger health condition survey to assess health and thermal comfort. Indoor environmental thermal measurements included temperature in three locations: kitchen, living area, and bedroom and data were recorded every 15 minutes over 5 full days and 448 points. Study results start to indicate that older adults for Sunnyslope Manor preferred temperatures between 76 and 82.5 degrees Fahrenheit and that lower temperatures as outlined by ASHRAE-55 2010 increases the rate of injuries and mood changes in older adults among other findings.
