Australia’s low fertility rate is commonly attributed to deliberate decisions by women to avoid having children. Existing theoretical explanations of fertility decision-making mostly view childbearing as a rational, voluntary process and focus on the ‘costs’ to women of having children. Although this may help explain why women do not have children, it contributes very little to understanding why women do have children. This study describes childbearing desires, expectations and outcomes in a population-based sample of 569 30–34-years-old Australian women recruited from the Australian Electoral Roll in 2005. Most women surveyed wanted to have children, and their childbearing outcomes were associated with biological, psychological and social factors including the lack of a partner and adverse health conditions. The factors and their relative importance varied by parity. Most women had fewer children than they desired, and many would have children, or more children, if their circumstances were different. These data challenge prevailing assumptions about women’s childbearing behaviour that women are able to choose when and if they have a child. Based on the findings, a conceptual framework of childbearing behaviour is proposed which builds on existing theoretical explanations to explain why women do and do not have children, differences by parity, and the role of circumstances in women’s childbearing behaviour. The findings and conceptual framework have implications for public policies, and indicate that multiple approaches are required which are sensitive to and address the barriers women face in family formation.  相似文献

Trees in urban ecosystems are valued for shade and cooling effects, reduction of CO2 emissions and pollution, and aesthetics. However, in arid and semi-arid regions, urban trees must be maintained through supplemental irrigation, in competition with other water needs. Currently, a comprehensive understanding of the factors which influence water use of urban tree species is lacking. In order to study the drivers of whole tree water use of two common species in the Los Angeles Basin urban forest, four sites in Los Angeles and Orange County were instrumented with sap flow and meteorological sensors. These sites allowed comparisons of the water use of a native riparian (Platanus racemosa Nutt.; California sycamore) and non-native (Pinus canariensis C. Sm.; Canary Island pine) Mediterranean species, as well as the spatial variability in water use under different environmental and management conditions. We found higher rates of sapflux (J O ) in native California sycamore as compared to non-native Canary Island pine. Within each species, we found considerable site-to-site variability in the magnitude and seasonality of J O . For Canary Island pine, the majority of inter-site variability derived from differences in water availability: response to vapor pressure deficit was similar during a period without water limitations. In contrast, California sycamore did not appear to experience water limitation at any site; however, there was considerable spatial variability in water use, potentially linked to differences in nutrient availability. Whole tree transpiration (E) was similar for the two species when water was not limiting, but Canary Island pine was able to withstand unirrigated conditions with a very low E. These results add to the currently small pool of data on urban tree water use and ecophysiology, and contribute to establishing a more quantitative understanding of urban tree function.  相似文献

Few studies have asked children directly about their experiences in out-of-home care. This study uses data collected from 180 nine- to-11-year-old children currently in out-of-home care who were asked about their perceptions and appraisals of out-of-home care. Analysis of variance and chi-square analyses were used to examine whether children's appraisals of their lives following removal from their families of origin differ as a function of age, gender, race/ethnicity, type and severity of maltreatment, length of time in out-of-home care, placement type, attachment to current caregivers, and rating of current caregiver/home. Youth who were sexually and emotionally abused, youth who were satisfied with their current caregivers and placements, and girls were more likely to state that their lives would have been worse had they remained with their families of origin. Youth who were physically abused were more likely to report that their lives would have remained the same. Children living in group care were more likely than those living in family foster care or with kin to report that their lives would have been better had they remained with their families of origin. Differences were not found between children living in family foster care and those living with kin nor did children's appraisals differ based on age, race, ethnicity, length of time in out-of-home care, neglect, or severity of maltreatment.  相似文献

We investigate the effect of parenthood on whether non-marital unions led to marriage or parting for two cohorts of British women when they were aged between 16 and 29. We compare the effect of conceptions leading to births and the presence and characteristics of children on the odds that a cohabitation was dissolved, or that it was converted to marriage, for women born in 1958 and 1970. A multilevel, multiprocess, competing-risks model allows for multiple cohabitation per woman and endogeneity of fertility status. We find that cohabiting couples' response to impending parenthood and the presence of children changed over time. In particular, the proportion of cohabiting couples who married before a birth decreased and, in the 1970 cohort only, the risk of dissolution declined during pregnancy. There is also evidence that the presence of a child cemented a cohabiting union for women from the 1970, but not the earlier, cohort.  相似文献

Media have represented blame in homicide cases as attributable to a victim or an offender; we provide a more nuanced category of shared blame. We examine stories covering young homicide victims to demonstrate how shared blame is operationalized in print news, noting stark differences across a victim’s race and gender. We conduct a content analysis of the Orlando Sentinel newspaper and police reports from Seminole County and Sanford, Florida, from 2000 to 2012. Stark racial and gender differences are apparent in the way the content is framed and how the victims are depicted. The newspaper’s representation of young African American males is consistent with existing stereotypes of the “criminal black man.” We discuss the larger implications of our findings and how our results apply to high-profile killings of young homicide victims including Trayvon Martin.  相似文献

Addictive disorders, such as pathological gambling and alcohol use disorders, frequently co-occur at greater than chance levels. Substantive questions stem from this comorbidity regarding the extent to which shared variance between gambling and alcohol use reflects a psychological core of addictive tendencies, and whether this differs as a function of gender. The aims of this study were to differentiate both common and unique variance in alcohol and gambling problems in a bifactor model, examine measurement invariance of this model by gender, and identify substantive correlates of the final bifactor model. Undergraduates (N = 4475) from a large northwestern university completed an online screening questionnaire which included demographics, quantity of money lost and won when gambling, the South Oaks Gambling Screen, the AUDIT, gambling motives, drinking motives, personality, and the Brief Symptom Inventory. Results suggest that the bifactor model fit the data well in the full sample. Although the data suggest configural invariance across gender, factor loadings could not be constrained to be equal between men and women. As such, general and specific factors were examined separately by gender with a more intensive subsample of females and males (n = 264). Correlations with motivational tendencies, personality traits, and mental health symptoms indicated support for the validity of the bifactor model, as well as gender-specific patterns of association. Results suggest informative distinctions between shared and unique attributes related to problematic drinking and gambling.  相似文献

The paper reports findings of two quasi-experimental, propensity score matched (PSM) studies on the effects of Imagination Library (IL). IL is a community book-distribution program targeting improved caregiver–child literacy interactions, which are hypothesized to lead to increased school readiness – consisting of improved emergent literacy skills and social-emotional school readiness. In Study One, interviews were used to examine proximal increases in the quality of child–caregiver literacy interactions with 112 PSM families (IL?=?56; non-IL?=?56). Small effects were observed in Study One favoring IL families on reading interactions (d?=?.043). In Study Two, 378 PSM kindergarten students (IL?=?189; non-IL?=?189) were compared with regard to standardized tests of emergent literacy skills and social-emotional school readiness – distal outcomes of IL. No effects were observed in Study Two. Taken together, these two studies run counter to prior reports on the effects of IL and suggest that more must be done to improve emergent literacy and school readiness beyond simply providing free books.  相似文献

In a previous paper it has been shown that across three cohorts of men and women born in Britain in 1946, 1958 and 1970 a gender difference exists in regard to relative rates of class mobility. For men these rates display an essential stability but for women they become more equal. The aim of the present paper is to shed light on the causes of this trend—or, that is, of increasing social fluidity—among women. We begin by considering a refined version of the perverse fluidity hypothesis: that is, one that proposes that part‐time work leads to increasing downward worklife mobility among women that also entails downward intergenerational mobility and thus promotes greater fluidity. We do in fact find that the increase in fluidity is very largely, if not entirely, confined to women who have had at least one period of part‐time work. However, a more direct test of the hypothesis is not supportive. We are then led to investigate whether it is not that part‐time working itself is the crucial factor but rather that women who subsequently work part‐time already differ from those who do not at entry into employment. We find that eventual full‐ and part‐timers do not differ in their class origins nor, in any systematic way, in their educational qualifications. But there is a marked and increasing difference in the levels of employment at which they make their labour market entry. Eventual part‐timers are more likely than eventual full‐timers to enter in working‐class positions, regardless of their class origins and qualifications. Insofar as these women are from more advantaged origins, they would appear not to seek to exploit their advantages to the same extent as do full‐timers in order to advance their own work careers. And it is, then, in the downward mobility accepted by these women—who increase in number across the cohorts—that we would locate the main source of the weakening association between class origins and destinations that is revealed among women at large.  相似文献

The research literature on relational betrayal in a committed relationship has focused on the resulting trauma from the betrayal; however, few studies investigated the potential for posttraumatic growth following a relational betrayal. This study investigated the presence of posttraumatic growth in relationally betrayed women. The research focused on women's perceptions of the relational betrayal, and factors that facilitated posttraumatic growth. Results indicated relationally betrayed women perceived the betrayal as a traumatic event, to the extent that some met criteria for PTSD diagnosis. The passage of time was significant corollary to posttraumatic growth when moderated by a PTSD diagnosis. Finally, certain resources were reported to be more helpful than others in the development of posttraumatic growth. Clinical implications are presented.  相似文献
