How welfare reform affects young children: Experimental findings from Connecticut—A research note

As welfare‐to‐work reforms increase women's labor market attachment, the lives of their young children are likely to change. This note draws on a random‐assignment experiment in Connecticut to ask whether mothers' rising employment levels and program participation are associated with changes in young children's early learning and cognitive growth. Children of mothers who entered Connecticut's Jobs First program, an initiative with strict 21‐month time limits and work incentives, displayed moderate advantages in their early learning, compared with those in a control group. A number of potential mechanisms for this effect are explored, including maternal employment and income, home environment, and child care. Mothers in the new welfare program are more likely to be employed, have higher income, are less likely to be married, have more children's books in their home, and take their children to libraries and museums more frequently. However, these effects explain little of the observed gain in child outcomes. Other parenting practices and the home's social environment do explain early learning, but these remained unaffected by welfare reform. © 2003 by the Association for Public Policy Analysis and Management     

Journal Publishing, Journal Reputation, and the United Kingdom's Research Assessment Exercise

Many academic lawyers believe that the Research Assessment Exercise has encouraged writing for academic journals, often at the expense of other forms of scholarly discourse. Moreover, it is widely perceived that the reputation of the journal in which research is published affects how that research is assessed in connection with the RAE. In this article, the authors report data gathered from a large-scale study measuring the perceptions of academic lawyers concerning the journal publishing process, how the RAE has affected journal quality generally, and how specific journals rank in terms of academic quality and their perceived importance to the RAE process.     

The draw of home: How teachers' preferences for proximity disadvantage urban schools

This paper explores a little‐understood aspect of labor markets, their spatial geography. Using data from New York State, we find teacher labor markets to be geographically very small. Teachers express preferences to teach close to where they grew up and, controlling for proximity, they prefer areas with characteristics similar to their hometown. We discuss implications of these preferences for the successful recruitment of teachers, including the potential benefits of local recruiting and training. We also discuss implications for the modeling of teacher labor markets, including the possible biases that arise in estimates of compensating differentials when distance is omitted from the analyses. This study contributes to the literature on the geography of labor markets more generally by employing data on residential location during childhood instead of current residence, which may be endogenous to job choice. © 2005 by the Association for Public Policy Analysis and Management.     

Command-level Police Officers’ Perceptions of the “War on Cops” and De-policing

Policing has been the subject of intense public scrutiny for the better part of two years after several high-profile police killings of unarmed African Americans across the United States. The scrutiny has been so extreme that some contend there is currently a “war on cops”—whereby citizens are emboldened by protests and negative media coverage of the police, and are lashing out by assaulting police officers more frequently. In response, it is argued that officers are de-policing (i.e. avoiding proactive stops). We surveyed command-level police officers from a southeastern state about their attitudes concerning the war on cops and de-policing. The majority of our sample believed there has been a war on cops over the last two years. Moreover, officers who felt strongly about the existence of a war on cops were more likely to believe that de-policing is common among officers in today’s world of law enforcement.     

Statistical analysis of DNA mixtures using peak area information and allelic drop out

A case of a woman killed in Perugia is reported. The woman was beaten to death and the body showed evidence of bites, kicks and punches. The request of the Court was to verify the presence of bites and if they belonged to humans. Morphological examination and genetic analysis with human Y-specific markers were performed in order to verify the origin of the bites. The DNA profile from the surrounded area of the traces was compared with the profile of the victim's husband (the suspect).The results showed a match between the profile of the suspect and that of the traces for all loci examined. Due to the fact that also other relatives of the husband's male lineage lived in the same house, it was not possible to identify the man who really contributed to the traces. Therefore, the analysis was implemented with autosomal STR markers, which showed a mixed genetic profile. In order to verify the number and the identity of the contributors, statistical analysis based upon peak area information was performed with Probabilistic Expert Systems.     

Fertility control in historical China revisited: New methods for an old debate

We revisit the debate over the deliberate control of reproduction in historical China through a reanalysis of data from the Qing (1644–1911) Imperial Lineage that accounts for physiological or other differences between couples that affected their chances of having children. Even though studies of contemporary and historical European fertility suggest that failing to control for such differences may obscure evidence of parity-specific control, previous studies of historical Chinese fertility have not accounted for them. We show that in the Lineage, failure to account for such differences leads the association between the number of children already born and the chances of having another birth to appear to be positive, but that once they are accounted for properly, the relationship is inverted. Based on this, we conclude that lineage members adjusted their reproductive behavior based on the number of children. We also show that the sex composition and survival of previous births affected reproductive behavior. We conclude by suggesting that one way forward in the ongoing debate over fertility control in historical China is through application of such methods to other datasets and comparison of results. We also suggest that progress in the debate over fertility in historical China has been impeded by confusion over the definition of fertility control, so that some behaviors are recognized as fertility control by some parties in the debate but not others.     

Wealth stratification and reproduction in Northeast China, 1866–1907

Although the importance of material wealth to population growth is the core of Malthusian theory about population dynamics in pre-transitional societies, our understanding of the relationship between wealth and reproductive success in China is still limited. Until recently, there was little in the way of relevant data. In the absence of empirical evidence to the contrary, conceptions of the Chinese demographic regime were largely Malthusian, in that they did not account for the possible role of a fertility-based preventive check. In this study, we examine wealth differentials in reproduction in historical rural China by using newly available longitudinal individual level demographic and household level land holding data for 108,100 immigrants and their descendants living in 120 villages in Shuangcheng, Northeast China, between 1866 and 1907. Our study demonstrates a positive correlation between land holding status and marital fertility among the population under study. In addition, there is also a clear pattern of fertility differentials according to household context and other measures of socioeconomic status. Our findings suggest that these fertility differentials are not only results of certain social institutions and customs but also the consequences of couple's behavior of fertility control in response to socioeconomic and other household conditions.
