Parenting and child experiences in shelter: A qualitative study exploring the effect of homelessness on the parent–child relationship

Depending on the data source, between half a million and 2.48 million children in families experience homelessness each year in the United States. Recent data suggest that approximately half of all homeless children are under the age of 6. A considerable body of quantitative research has documented the occurrence of poor outcomes associated with childhood homelessness in the domains of social–emotional development, physical and behavioral health, academic achievement, and family stability. This qualitative study presents results from 19 interviewers with formerly homeless parents reflecting upon how the experience of being homeless affected their young children and their ability to parent. Findings are contextualized within an attachment perspective. Parental reported effects included confusion, sadness, anxiety or depression, withdrawal, lack of appetite, aggression, and disregard for authority. Parents also talked about the disempowering experience of parenting while in shelter. Unexpectedly, parents of infants said their children were not affected by homelessness, and few parents identified the need for mental health services for their children. The experiences of parents with whom we spoke provide invaluable insight into what shelter staff, social service agencies, philanthropy, policymakers, and researchers can do to support and respect the parent–child relationship in families who are experiencing homelessness.     

用EMME/2软件来估计0-D矩阵的实用方法

本研究的目的是用精确的数据来获得更准确的0－D矩阵．这些数据诸如TCSO－D矩阵,观测的路段交通量和通过EMME／2获取的快速公共论车O－D矩阵。首先,建立每个收费站的一个有效区域,每个收费站的出入量被分配到有效区域中的小区,这一分配好的0－D矩阵再被分配给由所有收费站和它们的有效区域组成的网络．其次,我们校正区域0－D矩阵,排除TCSO－D矩阵,目的是反映现测到的交通量,而将快速公共汽车和分配的路段交通量作为额外的交通量．与实际交通量相比,用估算过的交通小区0－D矩阵分配的交通量在整个公路网中只产生17．9％的偏差,并且分配的路段交通量和计算出的交通量的差异在所有计算的路段中大大减少．     

The Economic Value of Bilingualism for Asians and Hispanics1

This study examines how bilingualism affects the wages of Asian and Hispanic workers using 2000 Census data. In contradiction to the general belief that bilingualism can provide a competitive advantage in the labor market, we find no evidence that 1.5‐generation and U.S.‐born Asian and Hispanic bilingual workers generally have higher wages than their English monolingual co‐ethnics; in some cases, in fact, their wages are significantly lower. In search of specific circumstances under which bilingualism might provide an economic advantage, we also examine interactions of language with such variables as education, employment in the public rather than the private sector, and the size of the population of mother‐tongue speakers. With limited exceptions, we find no sign of greater economic returns to bilingualism. Since bilingualism requires considerable effort to maintain across generations in the United States, we conclude that the virtual absence of economic rewards for it creates pressure for linguistic assimilation.

The role of impulsivity,cognitive bias,and reasoned action in understanding college student gambling

Factors related to gambling behavior among college students in the USA are examined by applying the theory of reasoned action (TRA) and incorporating the concepts of impulsivity and cognitive bias. This study uses a broader approach to analyze gambling behavior by including financial behavior variables using ordinary least squares (OLS) and logistic regressions. The survey data were collected through a self-administered online questionnaire of college students from 19 colleges and universities in the fall of 2010. With a sample of 5024 college students, a majority of the respondents (84.45%) in this study report that they did not gamble in the last 30 days. The results of multivariate analysis indicate that gambling is related to attitudes toward gambling, cognitive bias toward gambling, subjective norms of family members regarding financial behavior, and impulsivity. Underestimation of financial behavior (cognitive bias toward financial behavior) was found to be associated with only gambling frequency but not gambling propensity.     

Testing for a unit root in an arima(p,1,0) signal observed with ma(q) noise

An ARIMA(p,1,0) signal disturbed by MA(q) noise is an ARIMA(p,1, p+q+1) process restricted by nonlinear constraints on parameters. For this model with a unit root the restricted maximum likelihood estimator (RMLE) of the unit root is strongly consistent and it has the same limiting distribution as the ordinary least squares estimator of the unit root in an AR(1) model tabulated by Dickey and Fuller (1979). A modified RMLE is proposed which has the same limiting properties as the RMLE and is computationally much simpler. Simulation results show that our unit root tests based on the modified RMLE perform very well for small samples and compare favorably with the Said and Dickey (1985) tests with respect to both sizes and powers. An illustrative example from sample survey is given.     

Disclosures and Asset Returns

Public information in financial markets often arrives through the disclosures of interested parties who have a material interest in the reactions of the market to the new information. When the strategic interaction between the sender and the receiver is formalized as a disclosure game with verifiable reports, equilibrium prices can be given a simple characterization in terms of the concatenation of binomial pricing trees. There are a number of empirical implications. The theory predicts that the return variance following a poor disclosed outcome is higher than it would have been if the disclosed outcome were good. Also, when investors are risk averse, this leads to negative serial correlation of asset returns. Other points of contact with the empirical literature are discussed.
