This essay concludes a special symposium on governance issues. All of the symposium articles raise serious questions about whether or not and how well governments in the United States are playing the several important roles they have in the governance process. This essay is about three changes that could lead to more effective, efficient, and equitable governance. Three interrelated ones are discussed: (1) Realizing a sustainable future, a new vision, and (2) initiating new decision making processes needed to deal with complex, inter-connected, conflict provoking issues, (3) requires new leadership.  相似文献

The study of leadership emergence has increased substantially over the past few decades. However, due to a lack of integrative theory, we believe limited advancement has been made regarding the full process of leadership emergence. To address this concern, first, we conceptualize the leadership emergence process from a complexity perspective and define emergence as a dynamic, interactive process grounded in three principles of emergent phenomena. Second, we review how previous research has modeled leadership emergence by focusing on the content areas of the lower-level elements, the mechanisms that facilitate their emergence, and the dynamism of the process once it has emerged. Third, based on the findings from the review, we introduce a process-oriented framework of leadership emergence. Fourth, we offer propositions to guide developing and testing emergent leadership processes, and we conclude with recommendations for future leadership process research. Our hope is that by realigning the study of leadership emergence with complexity and multilevel theory, we can reorient this area to focusing more on the process mechanisms within emergence, connecting back to research progress made over 60?years ago.  相似文献

Previous research studies and anecdotal evidence portray shooting galleries as locales that place injection drug users at great risk for HIV infection, drug use and violence. Collectively, these studies highlight the need to intervene with injectors who frequent shooting galleries. However, few researchers have studied an often-forgotten risk group – women injecting drug users who frequent shooting galleries – and compared their risk behaviors to their male counterparts. To address this gap in the research literature and to evaluate the functionality of the shooting gallery as a setting for HIV prevention, we collected data on risk practices from 201 injectors (101 men and 100 women) who were recruited from eight shooting galleries in Miami, Florida. Results indicate that, compared with men, women injectors engaged in a similar variety and frequency of injection risk behaviors and had more shooting companions. While only minor gender differences were apparent, relatively few injectors – male or female – adhered to current recommendations for needle hygiene practices. Needle hygiene practices existed equally among injectors of both sexes, however very few adhered to current recommendations. Furthermore, contrary to common images of shooting galleries, use of other drugs was infrequently reported, episodes of violence or victimization were uncommon, and sexual contact almost never occurred. Operators of shooting galleries, both men and women, indicated their willingness to participate in HIV prevention efforts. Implications of these findings for HIV intervention indicate that (1) there is a great need to intervene with both men and women IDUs who frequent shooting galleries and that (2) shooting galleries can be an optimal setting for HIV prevention.  相似文献

Foster care involvement due to parental substance use is a common problem with many challenges associated with service delivery. Using administrative data from a Midwestern state between the years 2009 and 2015 (= 17,420), this study examines characteristics of substance-abusing families at the time of entry into the foster care system and estimates the risk of reentry subsequent to reunification. Bivariate findings and survival analysis for reentry suggests substance-using parents are more likely to be involved in additional allegations associated with foster care involvement. These results highlight the need for improved services integration and coordinated delivery among service systems.  相似文献

Prior studies on longitudinal continuity of adversity have mostly examined persistence of individual adversity, rather than of families and have focussed mainly on material disadvantage. However, adversity is multi-dimensional, and in the case of families with children, it includes psychosocial as well as material elements. While both material and psychosocial elements are recognized as critical to child development, these aspects of family adversity are often studied in isolation and there is a dearth of longitudinal evidence on the extent to which such factors are transient or persistent. Using the first three waves (2004–2005, 2006–2007, 2008–2009) of the longitudinal study of Australian children this paper investigated the consistency and continuity of multiple adversity in families with children using material and psychosocial indicators. First, longitudinal factor analysis determined that a consistent factor structure of multiple adversity adequately fit the data longitudinally. Second, cross-tabular analysis showed significant changes in the prevalence of specific adversities over waves. In particular adversity related to changes in family composition and social support followed an increasing trend. Adversity in two material elements—economic status and hardship—decreased over time. Third, variance-components models revealed that though aggregate scores of material and psychosocial adversity indicated a high degree of continuity over time, continuity in disaggregated measures showed that within families a great deal of variability in adversity occurs, with intra-class correlations ranging from 0.27 to 0.84. The more persistent forms of adversity—family, substance use, economic adversity—are areas where targeted interventions are feasible while employment conditions and time pressure are more transient and may require intervention at the population level to reduce overall prevalence of the adversities. Our study has reinforced the need to assess psychosocial adversity in studies of families with children as a balance to the more commonly utilized material adversity.  相似文献

A semantic network analysis of keywords in titles of studies published in Public Relations Review and the Journal of Public Relations Research was conducted to determine the salient keywords in public relations scholarship from 1975 to 2011. “Communication,” “PR,” “public,” “practitioner,” and “corporation” have been the most prominent keywords, and the association of “PR-practitioner” was the most salient keyword association in public relations scholarship consistently.  相似文献

Research suggests that workers with unanswered callings have poorer outcomes than those without callings; however, these studies have used small or homogeneous samples (Berg et al., 2010; Gazica & Spector, 2015). We aimed to replicate this finding using a nationally representative sample of 445 full-time workers. We compared key work and life criterion variables across three groups: individuals with answered callings, unanswered callings, and no calling at all. Results linked answered callings to benefits but, unlike earlier studies, suggested that unanswered callings were no worse than lacking a calling. These findings call into question the narrative that unanswered callings are associated with adverse effects, suggesting that career counselors may be able to facilitate discernment of a calling without having a negative impact on those for whom that calling goes unanswered. Research designed to test causal influences of these dynamics is an important next step for understanding the experiences of individuals with answered callings, unanswered callings, or no calling at all.  相似文献

Aggression is a known behavior in dementia, but there is little in the literature about risk to home-based caregivers in situations where severe aggression is present. This article examines this issue with a focus on what is known and where further research is needed. Rates of severe aggression by dementia care recipients against caregivers are estimated at greater than 20%, and may be the strongest predictor of nursing home placement. Measures containing both assessment of behavior and objective measures of caregiver trauma are needed, along with interventions aimed at educating and protecting caregivers while respecting communicative properties of behavior.  相似文献
