Over the past 50 years, a generally accepted theory about the evolution of aging has been developed. One common conclusion that has been deduced from this theory is that aging is inevitable in organisms in which there is a difference between offspring and parents. A recent paper by Sozou and Seymour questions this prediction using a mathematical model, but it remains to be seen whether their new results stand up to more general analysis.  相似文献

To Revise or Not to Revise?   总被引:1,自引:1,他引:0  
This personal analysis of the revision process of the ICIDH is set in the context of the international disability movement. With analogies to feminism, it shows how the medicalisation of disability is itself disablism and, while recognising many flaws in the revised version, encourages the disability movement to use the new version to its own advantage.  相似文献

Mobile dating applications (MDAs), such as Momo and Tinder, allow mobile phone owners to meet potential mates through social media, thus contributing to the radicalization of Chinese attitudes toward sex. Although these applications may gratify the needs of users for love and sex, the potential of risk is often overlooked. However, it should be considered in their decision regarding whether to meet a stranger or not. This study investigated the motivations and risks involved in the use of MDAs to meet strangers and the outcomes of using this technology. The results showed that sexuality was the only predictor of the reasons that people use MDAs to meet people offline for dates and casual sex. Among the perceived risks of mobile dating, only the fear of self-exposure to friends, professional networks, and the community significantly explained why users would not meet people offline for casual sex.  相似文献

Recent changes in older people's public care services in Nordic countries in particular in Finland and Sweden are based on implicit expectations that family members will increase their involvement in care. In Nordic countries, the care of small children has been acknowledged to be a social matter that concerns gender equality and the work life participation of both men and women, while the situation of working carers of older people is much less acknowledged. This study addressed the question of how Finnish working women who give care to their older parents argue for and against their decisions of working and caring and the meaning of work and care in these decisions. Majority of the interviewees emphasised the importance of work and refuted the idea of leaving work for care. The decision not to leave work for care was justified with worker identity, commitment to work, having no innate skills to be a carer, availability of support services and other carers and financial necessity. On the other hand, a few interviewees brought forward their willingness to leave work which was justified by constructing care as meaningful and valuable activity as opposed to meaningless paid employment, and with the intensification of work, and with ageing. Lengthy argumentation and several discursive tools indicate that women anticipated moral blame for the decision of giving work primacy over care, but also for leaving work. Thus, working carers balance between contrasting expectations to care and to work.  相似文献

The study investigates the relationship between premigration experiences with autocracy and immigrants' participation in politics in the host country. Using a survey of about 2000 immigrants in Quebec (Canada) interviewed over telephone or with an online questionnaire, it assesses two possible pathways regarding the effect of premigration with autocracy on participation in the host country politics. One pathway emphasizes a reluctance to participate where experiences with autocracy would hinder participation in the host country. The second pathway posits a reluctance to disclosure where experiences with autocracy leave immigrants with a lasting hesitation to reveal the extent of their participation. Our findings lend weak support for a reluctance to participate and instead suggest a reluctance to disclosure. These findings raise questions about our capacity to accurately portray the preferences and behaviours of immigrants, here those who experienced autocracy in the country of origin, and highlight the sensitivity of findings regarding immigrant integration to interview modes.  相似文献

Using data from the Statistics on Income and living conditions of families with migrants carried out by ISTAT in 2009, we empirically examine the effect of micro level determinants on Moroccans’ return migration intentions. Although Moroccans living in Italy do not have a clear aspiration to return, the socio‐economic and work conditions in Italy determine their migration intentions. Furthermore, our research led us to argue that macro‐level determinants should also be considered. In particular, emigration, immigration and integration policies represent key elements in the analysis of the dilemma between to stay or to return. Therefore, the promotion of long‐term immigration policies, which allow the achievement of a permanent residence in the host country, combined with institutional reforms, which make the origin country socially, economically and politically more attractive for migrants are essential to complete the debate about to stay or to return.  相似文献

Abstract

Rubella is common among young adults. The most important consequences of rubella are fetal anomalies resulting from maternal rubella infection in early pregnancy. Health officials strongly advocate a mandatory rubella immunization policy for college students, leaving school officials the dilemma of deciding how to implement it.

To effectively prevent a rubella outbreak, a herd immunity of ≥ 95% is needed. This can be accomplished either by: 1) screening all students who do not provide a valid rubella immunization certificate and giving the vaccine to those with negative titers, or 2) vaccinating all of them without prior testing.

At the Medical College of Virginia (MCV), we have shifted our approach of rubella prevention from “screening first” to “vaccinating without prior testing.” We analyzed data from the past 6 years of our rubella prevention program and found that the latter approach was safe and simpler to administer. Decision analysis reveals that this approach can achieve an identical herd immunity of 99.45%, with a 45% cost savings compared to the “screening” approach. Threshold analysis indicates that unless the cost of the lab test is less than that of the vaccine, or the incidence of adverse reactions and associated treatment costs escalates 23 fold, the decision to vaccinate every student is still favored. We conclude that our decision to vaccinate without prior testing is a sound decision based on available data

“Intra-Blood-Brain-Barrier Synthesis of HTLV-III-Specific IgG in Patients with Neurologic Symptoms Associated with AIDS or AIDS-Related Complex,” LIONEL RESNICK, et al. Intra-blood-brain-barrier production of virus-specific antibody is good evidence of infection within the blood-brain barrier. Patients with the acquired immunodeficiency syndrome (AIDS) have an increased incidence of neurologic abnormalities—i.e., unexplained, diffuse encephalopathy manifested clinically as chronic progressive dementia. To define the role of human T-cell lymphotropic virus Type III (HTLV-III), the etiologic agent of AIDS, in the pathogenesis of neurologic dysfunction, we compared cerebrospinal fluid and serum from patients with neurologic symptoms associated with AIDS and the AIDS-related complex for the presence of antibodies directed agains HTLV-III. Antibodies directed against HTLV-III antigens were detected by four immunologic tests: a fixed-cell immunofluorescence assay, an enzyme-linked immunosorbent assay, immunoblots of viral lysates, and immunoprecipitation of cellular lysates. All patients were seropositive, and 22 of 23 (96 per cent) had HTLV-III-specific antibodies in their cerebrospinal fluid. Unique oligoclonal IgG synthesis within the blood-brain barrier was elevated. In eight of nine patients tested, the enzyme-linked immunosorbent assay showed that the percentage of HTLV-III-specific IgG in cerebrospinal fluid was higher than in serum, suggesting that HTLV-III infection of neurologic tissue occurs in the majority of patients with neurologic disease associated with AIDS or its related complex.

This study estimated a path model of women's forceful sexual fantasies. Constructs examined were childhood sexual abuse, feminist beliefs, sexual guilt, erotophilia, and sexual experience. The study clarifies how these factors mediate one another in relationship to forceful sexual fantasies, and is first to examine the effects of feminist beliefs on forceful sexual fantasy. Adult women (N = 261) participated by completing an online survey. A path from sex guilt to forceful sexual fantasy, mediated by erotophilia, was found, wherein low levels of sex guilt and high levels of erotophilia were found to predict forceful sexual fantasy. A direct path between childhood sexual abuse and forceful sexual fantasy was also found. The resulting model is discussed in relation to previously-proposed theories on the role of force in women's sexual fantasies.  相似文献

The debate over the "Rise of the West" has generally been over which factor or factors—cultural, geoographic, or material—in European history led Europe to diverge from the World's pre-industrial civilizations. This article aims to shift the terms of the debate by arguing that there were no causal factors that made Europe's industrialization inevitable or even likely. Rather, most of Europe would not and could not move toward industrialization any more than China or India or Japan. Rather, a very accidental combination of events in the late seventeenth century placed England on a peculiar path, leading to industrialization and constitutional democracy. These accidents included the compromise between the Anglican Church and Dissenters, and between Crown and Parliament, in the settlements of 1689; the adoption of Newtonian science as part of the cosmology of the Anglican Church and its spread to craftsmen and entrepreneurs throughout Britain; and the opportunity to apply the idea of the vacuum and mechanics to solve a particular technical problem: pumping water out of deep mine shafts in or near coal mines. Without these particular accidents of history, there is no reason to believe that Europe would have ever been more advanced than the leading Asian civilizations of the eighteenth and nineteenth centuries.  相似文献

Prior research has largely failed to focus on how transgressors can promote trust when having made unfair offers in bargaining. I investigated in the context of receiving an unfair offer in a dictator game when financial compensations and when apologies are most effective in motivating trust behavior by the violated party. I hypothesized that when losses were allocated, the violated party would be motivated to show more trust behavior towards the transgressor when a financial compensation (resulting again in equal final outcomes) relative to an apology was delivered, whereas when gains were allocated, apologies would be more effective in promoting trust behavior than a financial compensation. Results from a laboratory study indeed supported this prediction as such demonstrating the importance of how allocation decisions are framed (i.e., loss or gain) in testing the effectiveness of trust repair strategies (financial compensations vs. apologies).  相似文献

A successful democratic consolidation of post-socialist societies depends, among other things, on their citizens’ political culture, younger generations included. Moreover, youth civic engagement today and in the future is a guarantee of the continuity and development of democracy, which means that scientists need to gain insight into young people’s political culture. In this paper we look at political values, institutional trust and participation as relevant components of the civic political culture. The analysis is based on quantitative data collected in the empirical studies of Croatian youth, carried out between 1999 and 2013. Based on longitudinal study results, a downward trend is identified regarding selected political culture indicators: acceptance of liberal-democratic values, trust in social and political institutions, interest in politics and party preference. However, there is a simultaneous increase in participation in various types of organizations, especially political parties. The interpretation of established tendencies is placed in a broader context of an inherited democratic deficit, economic recession and social crisis. Current trends are both indicators and consequences of young people’s inadequate political socialization as well as weaknesses of political institutions and various actors during the transition and consolidation period.  相似文献

Educational globalization is taking place amid the competing narratives of hyperglobalization and deglobalization. This article shows that these narratives fail to capture what is really happening. Aggregate empirical data for the period since the 2008 financial crisis evidence neither an appreciable rise nor a substantial decline in the overall level of globalization. Against this backdrop, a grid of risks that market-based university reforms pose to the soul of the university can be garnered from five scholars’ comments on the author of this article’s book Implausible Dream: The World-Class University and Repurposing Higher Education. The risk factors are bracketed under the following headings: control mechanisms and diminishing reflexivity, misrule, numerical governance, the ethos of competitiveness, and the conventional organization of knowledge. This calculus of risks has important implications for crafting strategies for derisking the core purposes of higher education institutions. They revolve around a central motif: strengthening the democratic tradition at universities.  相似文献

This article explores whether it is fruitful to use a service user/survivor approach to recovery, by seeing recovery as survival of social invalidation. That is survival of the psychosocial forces that were the source of the experience of mental distress, and as survival of social oppression by the psychiatric services and/or wider society. It could be argued that the participants in this study in the United Kingdom and Sweden recovered, and reclaimed and (re)constructed positive identities. They actively resisted experiences of disablism and rebuilt their lives. By approaching recovery from a service user/survivor perspective, one is focusing on the social, structural and political aspects of the recovery process, and one is resisting biomedical, deviant and reductionist notions of recovery.  相似文献

Sharing stories about the past and about being in care, can help adolescents placed in foster families to make meaning of their experiences and connect with their conversation partner. However, what obstacles and opportunities for sharing stories are experienced by foster youth has not been researched, while this holds important implications for research and practice. In an episodic interview, thirteen adolescents and young adults (16–23 years) talked about their experiences with sharing their memories about their past and being in foster care. Using a thematic analysis, two themes were constructed, each containing three sub-themes. The theme ‘When’ included references to the prerequisites for talking and considerations made by participants, and contained the sub-themes ‘How often do I talk’, ‘Conditions’ and ‘Ownership of my story’. The theme ‘Why’ included references to the rationales for sharing or not sharing memories, which contained the sub-themes ‘Protection’, ‘Understanding’ and ‘Processing the past’. The stories of the participants highlight both the opportunities and obstacles for talking. Foster parents and foster care workers should be aware of the needs foster youth have with regard to conversations about their experiences and should try to facilitate the meaning-making processes, although some foster youth prefer managing their memories in a more private way.  相似文献

Despite recent interest in political ethnography, most of the reflection has been on the ethnographic aspect of the enterprise with much less emphasis on the question implicit in the first word of the couplet: What is actually political about political ethnography and how much should ethnographers pre-define it? The question is complicated because a central component of the definition of what is political is actually the struggle to define its jurisdiction and how it gets distinguished from what it is not. In this article we aim to show how ethnography can actually lead us out of this conundrum in which the political is paradoxically both predefined and, at the same time, the open question that leads the process of inquiry. We do so by advancing a formal and relational approach that provides us with procedural tools to define the nature and specificity of the political bond not ex ante, but rather during the process of research itself. In the first part of the article we historicize the development of political ethnography as a distinct avenue for inquiry and show what have been the challenges to its normalization. This is followed by the article’s main section, which focuses on the four ways in which what is political has been conceptualized in contemporary socio-ethnographical literature. In the conclusion of the article, we advance a lowest common denominator definition proposal, with examples from other scholars as well as from our own research to illustrate how this approach would work.  相似文献

In politics, there is an offline power imbalance between the Educated and the Less Educated caused, in part, by the fact that those individuals with more extensive levels of education are more equipped to influence the political process. This study analyses the impact of Internet use on this imbalance and investigates whether the disparity remains intact in the Digital Age. Accessibility to the Internet is somewhat agnostic to one’s education and may be a quick and cost-effective tool to affect the political process. This study employs the concept of online political efficacy (OPE), which is likely to impact online political participation (OPP), to test whether Internet use provokes a sense of political effectiveness in the less educated to a greater extent than those more educated. Internet Service Types, particularly social media, were found to be positively associated with OPE to a much greater extent among the less educated. These findings indicate that, as a result of an enhanced positive perception of the Internet from using the Internet Service Types, the less educated are likely to feel empowered to affect the political process to a greater degree than the educated. Such use, in turn, is more likely to lead the less educated to OPP. This flow in the context of Internet use and education levels was presented in the framework of the O-S-R-O-R model of communication effects. As such, Internet use has the potential to contribute toward an equalization of the offline power imbalance.  相似文献

The majority of works on Caribbean slavery, both contemporary and modern attribute to slave women a subordinate and passive role in slave resistance. By examination of every‐day acts of non‐cooperation, maronage, slave uprisings and the link between African religion and slave revolts, this paper argues that, on the contrary, women were active at all levels of slave resistance and made a significant and indispensable contribution to the slaves’ struggle against servitude. Particular attention is paid to the relationship between the West African cultural heritage of slave women and the nature of their participation in slave resistance. In conclusion it is suggested that this neglected area of the slave woman's life warrants further research as a crucial aspect of the slave experience in general.  相似文献
