“五四”后期周建人的婚恋观——以《妇女杂志》为考察依据

周建人在五四后期在恋爱、婚姻、离婚问题上更多地注重个体的自由、价值和觉醒。他认为，真诚的恋爱本是人生的花，是精神的高尚产品；理想的配偶选择应以个人本身性质上的各种美德为标准：以爱情的有无为婚姻离合的原则。婚恋的个人自由和独立有利于种族的完善、国家的进步，也是妇女解放和冲破家族制度的重要手段。因此，其婚恋观的一个重要诉求是男女平等，呈现出对妇女解放各个问题理性而具体的思考。     

Les agriculteurs dans la fabrique d'une nouvelle agriculture

The model of development that has governed the modernization of farming in France is increasingly coming under attack. Given this, analysing the “work” that farming performs to “translate” the criticisms with which it must cope in formulating new definitions of roles is important in order to understand changes under way in this sector. The changes undergone by farming over the past eighty years are briefly presented and then the procedures and results of a survey, conducted during the mad cow disease among beef-farmers in Burgundy, are described. Light is thus shed on the diversity of the positions that farmers have adopted with regard to the future of their occupation. An interpretation is proposed of how the distribution (and interplay between) these positions might affect agriculture. - Special issue on Agriculture and food.     

Potential exposures and risks from beryllium-containing products.

Beryllium is the strongest of the lightweight metals. Used primarily in military applications prior to the end of the Cold War, beryllium is finding new applications in many commercial products, including computers, telecommunication equipment, and consumer and automotive electronics. The use of beryllium in nondefense consumer applications is of concern because beryllium is toxic. Inhalation of beryllium dust or vapor causes a chronic lung disease in some individuals at concentrations as low as 0.01 microg/m3 in air. As beryllium enters wider commerce, it is prudent to ask what risks this might present to the general public and to workers downstream of the beryllium materials industry. We address this question by evaluating the potential for beryllium exposure from the manufacturing, use, recycle, and disposal of beryllium-containing products. Combining a market study with a qualitative exposure analysis, we determine which beryllium applications and life cycle phases have the largest exposure potential. Our analysis suggests that use and maintenance of the most common types of beryllium-containing products do not result in any obvious exposures of concern, and that maintenance activities result in greater exposures than product use. Product disposal has potential to present significant individual risks, but uncertainties concerning current and future routes of product disposal make it difficult to be definitive. Overall, additional exposure and dose-response data are needed to evaluate both the health significance of many exposure scenarios, and the adequacy of existing regulations to protect workers and the public. Although public exposures to beryllium and public awareness and concern regarding beryllium risks are currently low, beryllium risks have psychometric qualities that may lead to rapidly heightened public concern.     

Valuation of childhood risk reduction: the importance of age, risk preferences, and perspective.

This article explores two problems analysts face in determining how to estimate values for children's health and safety risk reductions. The first addresses the question: Do willingness‐to‐pay estimates for health risk changes differ across children and adults and, if so, how? To answer this question, the article first examines the potential effects of age and risk preferences on willingness to pay. A summary of the literature reporting empirical evidence of differences between willingness to pay for adult health and safety risk reductions and willingness to pay for health and safety risk reductions in children is also provided. The second dimension of the problem is a more fundamental issue: Whose perspective is relevant when valuing children's health effects—society's, children's, adults‐as‐children, or parents'? Each perspective is considered, followed ultimately by the conclusion that adopting a parental perspective through an intrahousehold allocation model seems closest to meeting the needs of the estimation problem at hand. A policy example in which the choice of perspective affects the outcome of a regulatory benefit‐cost analysis rounds out the article and emphasizes the importance of perspective.     

The Experience of Gender Change in Public Sector Organizations

The state has a twofold relationship to gender change in society, through its overall steering capacity and through the gendered character of its constituent agencies. It is therefore important to understand the experience of gender change in state organizations. The findings from a study of gender relations in ten public‐sector worksites in New South Wales, Australia are presented. There is a widespread consciousness of gender change linked with new labour processes, restructuring and new patterns of management. These changes are uneven and limits to change are visible. Gender is recognized as an organizational problem in specific circumstances, most visibly where men’s resistance to change appears. A number of mechanisms limit the consciousness of gender as a problem. Several trends, including the current strength of neo‐liberalism, converge to make the gender‐neutral workplace the principal goal of gender reform in the public‐sector workplace. This, however, limits the state’s steering capacity in regard to societal gender relations.     

Collapsing the Boundaries? Fatherhood,Organization and Home‐Working

In the modern western world, the discursive construction of fatherhood and everyday fathering practices has been underpinned by the spatial separation of work from home, of public from private. However, increasing numbers of employees are now working from home and a disproportionate number of these are men with young children. This article draws on new empirical research to examine the implications for fathers and for organizations as home‐working disrupts earlier spatial configurations of fatherhood and fathering practices. The article concludes that as the spatial boundaries between home and work collapse, new accommodations between fatherhood/fathering and organization are emerging. However, these are underpinned by a traditional gender division of labour in the household. More broadly, these findings confirm the inadequacy of static distinctions between public and private, showing that while such distinctions are still used to mark space and time, this is relational, contingent and unstable.     

Threshold decisions: how social workers prioritize referrals of child concern

This paper examines local authority social workers' decision‐making when considering referrals of children, where the concerns are on the margin of child protection procedures. In doing so, it describes the findings of a qualitative research study undertaken in the policy context of attempts to ‘refocus’ social work practice in the late 1990s and early twenty‐first century. Data collection involved interviews with social workers and parents in 23 cases. Conclusions are that referrals were evaluated on the basis of five key factors, specificity, severity, risk, parental accountability and corroboration, the use of which determined whether an initial assessment or an investigation of alleged abuse took place. The analysis builds on previous work in the child protection field, but demonstrates how the application of these factors differs between cases of child concern and cases of child protection. Policy implications concern the complexity of decision‐making in the uncertain context of limited referral information and it is proposed that the simplistic notion of a continuum of abuse is now outdated.

Child‐Care Usage and Mother‐Infant “Quality Time”

Mothers' time‐use patterns were compared in families in which infants spent more than 30 hours per week in child care (In‐Care group; n= 143) versus 0 hours per week (At‐Home group; n= 183) from birth to 6 months of age. In‐Care group mothers spent about 12 fewer hours per week interacting with their infants, for about 32% less time; fathers of these infants were more involved in caregiving. The groups did not differ in the quality of mother‐infant interaction. In the In‐Care group, quantity of interaction was related to greater separation anxiety and concerns about effects of maternal employment. Time‐use data were not related to child outcomes at 15 months of age. Results suggest that the effect of extensive time spent apart on the quantity and quality of mother‐infant interaction may be smaller than anticipated.

Premarital Cohabitation and Housework: Couples in Cross‐National Perspective

The authors examine the effect of premarital cohabitation on the division of household labor in 22 countries. First, women do more routine housework than men in all countries. Second, married couples that cohabited before marriage have a more equal division of housework. Third, national cohabitation rates have equalizing effects on couples regardless of their own cohabitation experience. However, the influence of cohabitation rates is only observed in countries with higher levels of overall gender equality. The authors conclude that the trend toward increasing cohabitation may be part of a broader social trend toward a more egalitarian division of housework.
