Lone Mothers and Welfare-to-Work Policies in Japan and the United States: Towards an Alternative Perspective

This paper compares recent efforts to reduce lone mothers\u27 reliance on cash assistance and support their increased participation in the workforce and economic independence in Japan and the United States. Similar to reforms introduced in the U.S. in 1996, lone mother policies in Japan have been subject to a series of cuts leading to the introduction of time limits and work-related programs in 2002. In this paper, we examine the character of recent welfare reforms in both countries and their implications for lone mothers\u27 welfare and economic independence. Based on Japan\u27s experience and recent lessons from the U.S., we show the limitations of a focus on caseload reduction and work participation rates, and instead highlight the importance of addressing lone mothers\u27 low wages in form of policies for the working poor

Cuticular Hydrocarbon Content that Affects Male Mate Preference of Drosophila melanogaster from West Africa

Intraspecific variation in mating signals and preferences can be a potential source of incipient speciation. Variable crossability between Drosophila melanogaster and D. simulans among different strains suggested the abundance of such variations. A particular focus on one combination of D. melanogaster strains, TW1(G23) and Mel6(G59), that showed different crossabilities to D. simulans, revealed that the mating between females from the former and males from the latter occurs at low frequency. The cuticular hydrocarbon transfer experiment indicated that cuticular hydrocarbons of TW1 females have an inhibitory effect on courtship by Mel6 males. A candidate component, a C25 diene, was inferred from the gas chromatography analyses. The intensity of male refusal of TW1 females was variable among different strains of D. melanogaster, which suggested the presence of variation in sensitivity to different chemicals on the cuticle. Such variation could be a potential factor for the establishment of premating isolation under some conditions

Pathway of the Association Between Child Poverty and Low Self-Esteem: Results From a Population-Based Study of Adolescents in Japan

Child poverty leads to various negative consequences, including low self-esteem, which is a risk factor for mental illness, suicide, or poor academic achievement. However, little is known about why child poverty leads to low self-esteem. We aimed to elucidate the association of child poverty and low self-esteem based on the ecological model, which includes family-level, school-level, and community-level factors. Data were obtained from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study in 2016, and participants included 1,652 children in fourth grade (534 pairs), sixth grade (530 pairs), and eighth grade (588 pairs) living in Adachi City, Tokyo, Japan. A questionnaire survey was implemented to assess child poverty, parental mental health, parental involvement with children, parental social capital by caregivers, and self-esteem and school social capital by children. The structural equation model was applied to elucidate the association between child poverty and low self-esteem, using family-level (parental mental health and parental involvement with children), school-level (school social capital), and community-level (parental social capital) factors. Child poverty was associated with low self-esteem. Child poverty leads to poor parental involvement, which can be indirectly associated with poor parental mental health and poor parental social capital, and poor parental involvement was directly or indirectly associated with low self-esteem through poor school social capital. To mitigate the impact of child poverty on low self-esteem, comprehensive health policies targeting family-level (parental mental health and parental involvement with children), school-level (school social capital), and community-level (parental social capital) factors may be effective

Risk Factors of Free Flap Complications in Reconstruction for Head and Neck Cancer

Background: Although head and neck reconstruction using free flaps has become a common procedure, flap complications remain a concern. This study aimed to analyze the risk factors of free flap complications and to identify the causes of these complications. Methods: We studied 97 patients with head and neck cancer with intraoral defects who underwent reconstruction using free flaps at Tottori University Hospital between 2011 and 2020. We used a retrospective cohort study design to investigate whether flap complications, including flap necrosis (total and partial) and flap dehiscence, were related to various factors, including the underlying disease condition, treatment status, and surgical factors. Results: Of the 97 patients analyzed, total flap necrosis was observed in one patient (1.0%). The incidence rate of flap complications, including flap necrosis and flap dehiscence, was 29.9%. When the time taken to perform one vascular anastomosis, including preparation of the recipient vessel and flap vessel, exceeded 30 min, the incidence rates of flap necrosis (total and partial) (odds ratio, 8.30; 95% confidence interval, 1.91-36.00; P = 0.005) and flap dehiscence (odds ratio, 3.46; 95% confidence interval, 1.05-11.36; P = 0.041) increased significantly. Conclusion: The time taken to perform one vessel anastomosis was the factor that contributed the most to the incidence of flap complications. Reconstructive surgeons should reduce the incidence of flap complications by keeping the known risk factors of the surgery in mind and by aiming to complete a vascular anastomosis time, including the time taken for the preparation of vessels, of ≤ 30 min per vessel during surgery

Parental Time of Returning Home From Work and Child Mental Health Among First-Year Primary School Students in Japan: Result From A-CHILD Study

Introduction: Child mental health is known to be influenced by parental work hours. Although literature suggests that parent-child interaction mediates the association, few studies have directly measured the parental time of returning home from work. We analyzed data from a school-based survey to examine the association between parental time of returning home from work and child mental health.Methods: We used a sample of 2,987 first-year primary school students derived from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study that examined the impact of family environment and lifestyle on child health in Adachi City, Tokyo, Japan. We analyzed the associations between reported parental time of returning home and the continuous Strengths and Difficulties Questionnaire (SDQ) scores using multivariable regression modeling.Results: Children whose parents both returned home late (later than 6 p.m. for the mother and later than 8 p.m. for the father), or at irregular times, had higher scores in total difficulties (β = 1.20, 95% CI: 0.55 to 1.85), the “conduct problems” subscale (β = 0.37, 95% CI: 0.13 to 0.60), and the hyperactivity/inattention subscale (β = 0.53, 95% CI: 0.24 to 0.82) compared with children whose parents both returned home earlier. Mediation analyses indicated that the percentage of the total association between parental time of returning home and the SDQ scores, which was mediated by parent-child interaction, was 20% (95% CI: 10 to 46) for total difficulties, 17% (95% CI: 7 to 49) for conduct problems, and 23% (95% CI: 11 to 52) for hyperactivity/inattention.Conclusions: Late or irregular returning home times for both parents had an adverse effect on child mental health, and the relationship was partly mediated by reduced frequency of parent-child interaction

A Study on High School and Undergraduate Students’ Learning Motivation : A Case of Joint Management of the Educational Relationship between K Agricultural High School and A University for the “K Agricultural High School & A University Program"

This paper introduces the joint management of an educational relationship between K Agricultural High School and A University, and reports the program's effects to increase students' motivation for learning at both schools. In the program, first, the high school students presented the results of their project based learning, and the university students and university instructor gave comments. Next, the high school students received a lecture from the university instructor and a research report from the university student. Finally, the high school students, university students, and instructors attended a social gathering. An analysis of responses to the study questionnaire suggests that students’ motivation for learning increased at both schools, except the university students who have high motivation originally

Association of dental occlusal support with the Prognostic Nutritional Index in patients with esophageal cancer who underwent esophagectomy

Background The Prognostic Nutritional Index is useful for predicting surgical risk and overall survival based on preoperative immunological and nutritional status in patients undergoing digestive organ cancer surgery. The purpose of this study was to examine the association between the Prognostic Nutritional Index and dental status in patients with esophageal cancer who underwent esophagectomy. Methods This retrospective case–control study included 73 patients who underwent resection of esophageal cancer (69 males, 4 females; age 36–83). General and dental status were evaluated. The Prognostic Nutritional Index was calculated based on the serum albumin concentration and the total lymphocyte count, and subjects were divided into two groups based on index scores: a higher group, characterized by scores ≥ 45 (n = 54); and a lower group, characterized by scores Results Total protein, C-reactive protein, the number of sound and total decayed, missing and filled teeth, and the rate of patients with poor dental occlusal support showed significant differences between the lower and higher Prognostic Nutritional Index groups (p  Conclusion Dental status, especially dental occlusal support and the number of sound teeth, showed a positive relationship with the Prognostic Nutritional Index in esophageal cancer patients who underwent esophagectomy
