Nonparametric Instrumental Regression

The focus of this paper is the nonparametric estimation of an instrumental regression function ϕ defined by conditional moment restrictions that stem from a structural econometric model E[Y−ϕ(Z)|W]=0, and involve endogenous variables Y and Z and instruments W. The function ϕ is the solution of an ill‐posed inverse problem and we propose an estimation procedure based on Tikhonov regularization. The paper analyzes identification and overidentification of this model, and presents asymptotic properties of the estimated nonparametric instrumental regression function.     

说“禄养”——关于汉代官员养亲问题的考察

"禄养"是指官员以俸禄孝养父母。两汉时期,人们对禄养行孝的养亲方式非常崇尚,即使是那些淡泊名利的志节之士,在身处无力养亲的现实困窘时,有时也会迫不得已而放下身段,入仕求禄以求养亲。但是由于俸禄微薄,对于不少中低级官员来说,以禄养亲依然不易。不少官员为了便于行孝,往往会想方设法将父母迎接至就职地,此即"移亲就养"。但是在实际操作过程中,移亲就养并不容易实现,故有些官员不惜放弃官职以归乡终养。汉代已将"养亲"纳入官员的考核机制之中,但是总体而言,其在相关制度建设方面仍显粗疏。     

Care-giving Coping Strategies Among Mothers with Chronically Ill Children

ABSTRACT

The purpose of the study is to identify the types of stresses experienced and the coping strategies used by mothers who are responsible for providing care to their chronically ill and disabled children. A qualitative approach was selected to systematically document the experiences and highlight individual coping strategies. Purposive sampling was used in this qualitative pilot study, fifteen (15) mothers who were known to the researcher as well as two schools that specifically cater for children with disabilities were selected to participate in the study. Thirty questionnaires were handed out of which fifteen were returned. Data was collected using the coping Health Inventory for Parents (CHIP) to measure the extent to which parents perceived a number of coping strategies to be helpful in coping with the chronic illness of their child (ren). The scale comprised 45 items with 3 subscales. The results highlighted the types of stresses that were experienced by the mothers and the coping strategies practiced by these mothers when caring for their disabled children. Mothers who care for chronically ill children are faced with daily stress that relates to care as well as their personal life.     

Rural Homeless Shelters: A Comparative Analysis

Although there has been some increased attention to the issue of homelessness and homeless shelter services, little effort has been made to understand the operation of rural homeless shelters. This situation persists despite decades of effort showing that the rural environment provides a very different context for the delivery of services than an urban environment. This study hypothesized that contextual differences in rural environments would produce various strategies of service delivery among homeless shelters. A typology of rural environments was created. Homeless shelters within each of four cells of the typology were selected. Comparative case study analysis provided partial support for the hypothesis.     

Welfare Indignities: Homeless Women,Domestic Violence,and Welfare Reform in San Francisco

Using data collected during a 4 year ethnography, this paper examines how the 1996 Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) has impacted homeless women in San Francisco who are also victims of domestic violence. Specifically this paper looks at how the behavior of abusive men prevents homeless women from successfully navigating the new welfare-to-work requirements and maintaining stable employment. Findings indicate that despite the discourse touting the success of welfare reform, the 1996 PRWORA has further disenfranchised an already devastated population systematically forcing them further onto the margins of society.

Determining the birth function for an age structured population

This paper deals with an inverse problem in age‐structured population dynamics, namely the recovery of the unknown birth function from the additional or overposed data consisting of the total population over a time interval equal to the maximum life span of the species. Conditions on the data are given to guarantee the existence and uniqueness of a solution, and the question of continuous dependence of the birth function on the data is addressed. Some numerical simulations are presented to indicate that one can in fact use the methods of the paper to reconstruct the birth function.     

“Don't Leave Me Hanging”: Homeless Mothers’ Perceptions of Service Providers

ABSTRACT

Few interventions have been developed for substance-abusing homeless mothers. Among those interventions, high dropout rates (up to 85%) are consistently reported. Understanding homeless mothers’ experiences with service providers may be an important first step to understanding ways to increase treatment engagement. Therefore, the current study used qualitative methods to gain a better understanding of homeless mothers’ perceptions of service providers. A total of 28 mothers who were currently residing at a homeless shelter in a Midwestern city participated in three focus groups. Overall, mothers held negative perceptions of service providers related to understanding, support, and fear. Based upon this study's findings, recommendations are offered to improve service delivery and guide future research.     

Changing the method of working with homeless people: a photovoice project in Italy

In Italy, many organizations are experimenting with the Housing First (HF) model to promote a change in how they work with homeless people. This change creates some difficulties, especially in promoting freedom of choice in people involved in the HF programs. This study explored the definition of “home” in homeless people’s points of view. The study participants were 5 homeless men involved in a HF program called “The Road Home” implemented in the city of Padua. Data were collected using Photovoice, a photographic method based on participatory action research. During the project, the participants took photographs to illustrate their definitions of “home” and then engaged in a critical dialogue about the images represented in the photographs. The results of the study showed that occupants identified the home as being related to family, friendship, cohabitation, and hope for the future. The Photovoice project provided an opportunity to promote discussions that revealed the true needs of the people involved, and in the meantime, it brought a change to the program and to the community, in addition to promoting the HF model in the community.     

Family Support Groups for Family Members of Mentally Ill Offenders: Therapeutic Factors

This study investigates therapeutic factors of a Family Support Group (FSG) intervention for family members of mentally ill offenders. Seventeen family members completed the ‘Group Therapeutic Factors‐Client Questionnaire’ (GTF‐CQ‐28) during four sessions of two FSGs. Results indicate that family members experienced the following therapeutic factors over the course of treatment: the relational climate, interactional confirmation, expressing and experiencing mutual positive feelings, forgetting own problems, hope from seeing progress in others, guidance from therapists, and getting interpersonal feedback treatment. The therapeutic factors, including learning by observation, support from the group, and universality of problems, correlated with a decrease in self‐blame, improved emotional well‐being, and experiencing less loss of control over one's life, respectively. Further, family members were satisfied with what the FSG has provided for them personally and for the relation with their relative. Finally, clinical implications of the FSG are discussed. The study sheds light on valuable therapeutic factors within an FSG and the important role of therapists.
