THE SANDWICHED GENERATION: MULTIPLE CAREGIVING RESPONSIBILITIES AND THE MISMATCH BETWEEN ACTUAL AND PREFERRED WORK HOURS

We examine the intersection of the “Overworked American” and the “Sandwiched Generation.” Recent studies indicate that many U.S. workers would prefer to work shorter hours. For workers who are sandwiched between childcare and eldercare or who expect to be in the future, questions remain about work hour preferences. We use a representative sample and distinguish between currently sandwiched workers and those who expect to be in five years. The proportion of workers who are currently sandwiched has increased from 1992 to 2002. Further, workers who expect to be sandwiched are less likely to want to reduce their workweek hours than others.     

血管生成素通过ERK信号通路促进HeLa细胞的增殖

目的通过细胞外信号调节激酶（extracellularregulatedproteinkinases,ERK）通路及NF-xB信号途径探讨血管生成素（angiogenin,Ang）对HeLa细胞的促增殖及抗凋亡作用机制。方法用不同浓度的重组人Ang刺激HeLa细胞,MTr法分析Ang对HeLa细胞的促增殖作用,蛋白质印迹实验检测ERK信号通路相关分子的表达情况。U0126抑制ERK信号通路,检测Ang诱导的ERKl／2的磷酸化及c—myc的表达情况,同时检测Ang对细胞增殖的影响。敲低Ang的表达,检测细胞的凋亡情况。双荧光素酶报告基因检测Ang对NF-KB报告基因的激活。蛋白水平检测Ang刺激的HeLa细胞后,NF—KB通路相关分子的表达。结果Ang能促进HeLa细胞增殖,ERKl／2的磷酸化水平及c—myc的表达随重组人Ang浓度的升高而增加。U0126能抑制Ang诱导的ERKI／2的磷酸化、c—myc的上调及细胞的增殖。Ang的低表达促进HeLa细胞的凋亡,但不影响NF-KB报告基因的激活及NF—KB通路上相关分子的表达。结论Ang能够促进HeLa细胞增殖,并通过活化ERK通路促进细胞的增殖,但其抑凋亡作用与NF-KB通路无关。     

Choosing the best (wo)man for the job: The effects of mortality salience,sex, and gender stereotypes on leader evaluations

The present research investigated the impact of death-related thoughts on preferences for male and female leaders and tested alternative predictions derived from terror management theory: the stereotype bias effect was predicted to result in a global preference for male leaders (Study1) and a preference for agentic leaders (Study 2), whereas the ingroup bias effect was predicted to result in women favoring female leaders and men preferring male leaders. These hypotheses were examined in two experimental studies wherein participants were presented with a mortality salience or control manipulation and subsequently presented with campaign statements from male and female gubernatorial candidates. Results from Study 1 were in accord with the enhanced ingroup bias predictions: under mortality salience women preferred and voted for the female candidate more so than the male candidate, while men showed the reverse preference. Results from Study 2, which also manipulated gender stereotypic traits of the candidates, support the enhanced stereotype bias effect: under mortality salience female participants preferred and voted for the agentic candidate regardless of sex, and males preferred the agentic male candidate. Results support previous TMT research demonstrating both ingroup bias and stereotype bias processes.     

On the directional accuracy of inflation forecasts: evidence from South African survey data

We study the information content of South African inflation survey data by determining the directional accuracy of both short-term and long-term forecasts. We use relative operating characteristic (ROC) curves, which have been applied in a variety of fields including weather forecasting and radiology, to ascertain the directional accuracy of the forecasts. A ROC curve summarizes the directional accuracy of forecasts by comparing the rate of true signals (sensitivity) with the rate of false signals (one minus specifity). A ROC curve goes beyond market-timing tests widely studied in earlier research as this comparison is carried out for many alternative values of a decision criterion that discriminates between signals (of a rising inflation rate) and nonsignals (of an unchanged or a falling inflation rate). We find consistent evidence that forecasts contain information with respect to the subsequent direction of change of the inflation rate.     

Negotiating Partnerships in Research on Poverty With Community-Based Agencies

This article argues that researchers must negotiate true partnerships with poor women, maintain mutual support systems, and build mutual respect, if they are to have success in challenging poverty through research. The experience of establishing partnerships with community-based agencies is discussed and the rationale for including poor women in partnerships is considered in terms of the benefits and the challenges for researchers. Among the critical issues are problems of difference, including ethnicity, social class, and gender and relationships between researchers and participants. These issues are highlighted using two examples. A negative outcome from noncollaboration is represented by the case of an after-school program in an inner-city school. The failure to establish collaboration leads to disappointing results. A successful case is described by the cooperative efforts between researchers and poor women in a program for substance abuse. Several strategies and recommendations are offered in conclusion.     

Acts of Last Resort: Asylum,Whistleblowing and the Anthropology of Secrecy

Anthropologists face fresh challenges as they endeavour to conduct research in an increasingly securitised and secretive world. Those who wield asymmetrical power in society often seek to guard information and knowledge. Therefore, it is imperative that anthropologists seek new ways of navigating the politics of secrecy if they are to reveal anything of its inner workings. In pursuit of this imperative, this paper examines practices of whistleblowing and posits secrecy as a dialectic that is characterised by processes and practices that work towards concealment, as well as revelation. In shifting the analytical focus from that which is concealed to what is revealed in acts such as whistleblowing, we contend that anthropologists may elucidate something about secrecy that is revealing of context-specific forms of agency and power. In doing so, analysis draws upon Australia’s secretive immigration and border protection regime and in particular a recent government inquiry that enabled whistleblowers to reveal details of secrets that had previously been closely held.     

Target Problems,Time Limits,Task Structure

This paper documents the opportunities for student field training within university-based institutes on aging. Both the advantages and disadvantages of operating such field-work programs are analyzed. A practicum is proposed which reflects an emphasis on planning, administration, policy analysis, and program development. The benefits to students include collaboration with the allied professions, availability of specialized training resources, and emphasis on proposal writing and communication skills. Potential complicating factors for student learning grow out of the institute’s close proximity to academic accountability, the multiplicity of roles carried by field-instruction staff, and placement in an environment different from that of traditional service agencies.     

The television archive: A source for the sociological study of culture

In this essay the George Foster Peabody Collection and the WSB Atlanta Television News Archive are described. A discussion of the form, structure and content of the collections reveal that each are ideally suited to visual sociological investigation. In all, the textual body of visual imagery found in the Peabody collection is an important source for the study of culture. The collection offers access to fifty years of award winning audio and video recordings, spanning news, documentary, international, entertainment, public service and childrens program submissions, the WSB collection contains a rich array of materials that service to elaborate on a cultural and historic framework of the new and old south. Hard news stories along with documentaries reveal a variety of public and social rituals of historic importance, the WSB and Peabody collections can be accessed to fulfil a number of scholarly endeavors. Visual sociologists, anthropologists and communication scholars are encouraged to further explore the use of these two electronic media archives.
