Viewed through the lens of the dialogic theory of public relations, this study examines if universities use new media tools and how the world's top universities use Facebook as an interactive forum that give voice to key stakeholders. With the declining economy and limited access to resources, it is important to know how organizations utilize Web-based tools to build and maintain relationships at national and global levels. Because prior research found that users had negative feelings about lack of dialogue on college websites, it is also important to know whether universities are tapping into the dialogic potential. The content analyses of the websites and Facebook platforms show that more than half of the universities have Facebook pages. The results also show that users cannot post content or photos, or participate in discussions and wall posts. In essence, the voices of key stakeholders are being silenced via a media that is intended to provide open forums for dialogue.  相似文献

This article provides an overview of the ways in which the mistreatment and neglect of older people have come to be understood as a social problem, one which is underpinned by a variety of substantive and theoretical assumptions. It connects the process of conceptualizing elder abuse and neglect to political-economic and social evolution. The authors draw on a review of the literature, government sources, interest group websites, and their own research to provide a critical commentary illustrating how these understandings have become manifest in legislation, policies, and programs pertaining to "elder abuse and neglect" in Canada. Suggestions are provided for changes in direction for policies, programs, and research.  相似文献

Objectives: To understand predictors of first-year college adjustment in the context of collective trauma, including a school shooting. Participants: Two consecutive years of entering freshman (Year 1 (Y1) N = 169, Year 2 (Y2) N = 94) were surveyed over time: Y1 in October 2012 and March 2013, and Y2 in October 2013 and August 2014. During Y2, several collective traumas occurred, impacting the campus community and providing a stark comparison. Methods: Online surveys measuring predictors at the start of each year and adjustment at the end of each year. Results: Hope was the only significant predictor of adjustment when included in a regression model with depression symptoms in Y1, and with depression symptoms, baseline posttraumatic stress symptoms, and traumatic exposure in Y2. Conclusions: Fostering hope may promote college adjustment, regardless of collective traumas that might occur on campus.  相似文献

Introduction: The etiology of benign prostatic hyperplasia (BPH) remains a mystery to scientists; estrogen/androgen imbalance in aged men has been implicated.

Methods: Thirty (30) apparently healthy men and newly diagnosed BPH patients were recruited from the Ghana Police Hospital. Lower urinary tract syndrome (LUTS) and prostate volume were assessed via the prostate symptom score sheet (IPSS) and abdominopelvic scan, respectively. Laboratory assays for total prostate specific antigen (tPSA) and hormones [androstenedione (AED), testosterone (T), dihydrotestosterone (DHT), androstanedioladiol (3α-adiol), androstanediol (3β-diol), estrone (E1) and estradiol (E2)] were performed via ELISA techniques. Non-parametric analyses were employed. p?Results: AED was significantly higher in controls compared to the BPH patients. AKRIC2 (3α-diol/DHT) was significantly higher in the BPH group (p?p=?0.029). Age correlated negatively with T, while a negative correlation was observed between TIPSS and 3β-diol and AKRIC1. Also, prostate volume correlated negatively with fT.tPSA correlated positively with E2 and aromatase activity (E2/T) and negatively with fT. On multiple linear regression, DHT and 3β-diol remained independent predictors for TIPSS and fT for tPSA.

Conclusion: Estrogens and androstanediols seem to play a role in BPH development.  相似文献

Survey data from a U.S. Department of Agriculture funded multi-state longitudinal project revealed a paradox where rural low-income families from states considered prosperous were persistently more food insecure than similar families from less prosperous states. An examination of quantitative and qualitative data found that families in the food insecure states were more likely to experience greater material hardship and incur greater housing costs than families in the food secure states. Families in the food insecure states, however, did not have lower per capita median incomes or lower life satisfaction than those in the food secure states. A wide range of strategies to cope with food insecurity reported by families in both food insecure and food secure states was examined using the Family Ecological Systems Theory. Families in the food insecure states used several risky consumption reduction strategies such as curbing their appetite and using triage. Families in the food secure states, on the other hand, employed positive techniques involving their human capital.

The Age-Friendly Manitoba Initiative was launched in 2008. A formative evaluation we conducted in 2011 with 44 participating rural and urban communities demonstrates considerable progress, with virtually all communities having formed an Age-Friendly Committee and conducting a community assessment to identify priorities for action. The majority of communities implemented one or more age-friendly projects. Major barriers to becoming age-friendly identified by participants included lack of funding; lack of capacity, particularly in small communities; and lack of leadership or direction. The study highlights the importance of strong leadership at all levels of government (municipal, provincial, federal); the need to support communities, particularly rural ones, as they try to become more age-friendly; and the importance of ongoing promotion of age-friendliness locally and more broadly (e.g., provincially).  相似文献

A repeated theme, characterizing US social policies toward children and their families, is that the US has no explicit family policy, nor does it have a coherent package of social policies that are targeted on children and their families. Nonetheless, there is general agreement that the US does have policies that have consequences for children and their families, and that many of these might constitute 'implicit' family policies. However, these policies tend to be limited in scale, coverage, and generosity and are usually categorical and narrowly focused. They lack the comprehensiveness and universality of policies in other advanced industrialized countries. Furthermore, the US has consistently invested a significantly smaller share of GDP in children and their families than almost all the other such countries. One consequence is that the situation of children in the US seems to be much worse than that of children in other advanced industrialized countries. In more recent years, however, there have been some efforts at improving child and family policies and the story now is a mixed one—but there remain major deficits in our policies and programs. Fortunately, children's issues are emerging on the national policy agenda. In this article, we describe current US child and family policies, touch on earlier history for context, and discuss the issues facing the US as we enter the twenty-first century. Ultimately, we need to confront the question of what can be done now to advance the children's cause on the national agenda.  相似文献

This article argues that contemporary concern about ending child prostitution is misdirected in its strategy. Some theorists and activists, even the ILO, are seeking to create a distinction between adult and child prostitution as if child prostitution could be ended whilst adult prostitution remains intact. The motivation for the distinction relies upon trends in the 1990s to characterize men's prostitution abuse of adult women as constituting legitimate work, choice and agency for the women themselves, and to construct a profitable prostitution industry which can create profits for governments and sex industrialists. I will argue that child and adult prostitution are inextricably interlinked, both in personnel (the women and children work together), in terms of the abusers (who make no distinctions), in the harm they cause and in that both constitute harmful traditional practices which must be ended. The acceptance of men's prostitution abuse as the basis for the industrialization of adult prostitution increases the scale and harm of child prostitution. Thus only policies to eradicate all of men's abusive prostitution behaviour will serve to mitigate child prostitution.  相似文献

The bovine spongiform encephalopathy (BSE) maternal cohort study supports a role both for direct maternal transmission and for inherited genetic susceptibilty to the BSE agent. Additional data from the main BSE database do not resolve whether the risk of direct maternal transmission of BSE from dam to calf is concentrated in the interval within 5 months before the onset of BSE in the dam, as data from the BSE maternal cohort study suggest. The reason for this is that we cannot rely, as our analysis requires, on the survival of calves or traceability of the dam being independent of the interval from the birth of a calf to onset of BSE in the dam. Accordingly, for the present, we place most weight on evidence from the BSE maternal cohort study. Direct maternal transmission of the BSE agent from dam to calf has not been ruled out; vertical transmission of the new variant Creutzfeldt–Jakob disease (NVCJD) from mother with NVCJD to baby is therefore also possible. Actions to quantify, and minimize, the transmission risk, if any, from a mother with NVCJD to her baby, or to delivery teams, should be taken without delay.  相似文献
