Making Inter-country Comparison of Life Expectancy Inequality Sensitive

Two populations with the sameoverall longevity but different age andage-specific-mortality profiles may produce avariety of differences in terms of issues thatare relevant for development policy. A simplemethod of comparing countries has beensuggested in this paper, which is sensitive tosome of these differences that are usuallyhidden under life expectancy figures. In theprocess, some of the recent attempts inadjusting life expectancy for `inequality' havebeen critically examined.     

An Empirical Analysis of the Effect of Supply Chain Disruptions on Long‐Run Stock Price Performance and Equity Risk of the Firm

This paper investigates the long‐term stock price effects and equity risk effects of supply chain disruptions based on a sample of 827 disruption announcements made during 1989–2000. Stock price effects are examined starting one year before through two years after the disruption announcement date. Over this time period the average abnormal stock returns of firms that experienced disruptions is nearly –40%. Much of this underperformance is observed in the year before the announcement, the day of the announcement, and the year after the announcement. Furthermore, the evidence indicates that firms do not quickly recover from the negative effects of disruptions. The equity risk of the firm also increases significantly around the announcement date. The equity risk in the year after the announcement is 13.50% higher when compared to the equity risk in the year before the announcement.     

Trust,Social Networks and Subjective Wellbeing in China

Using data from the World Values Survey, this study examines the associations among trust, social networks and subjective wellbeing in China. We address the endogenous nature of trust and social networks, and examine how these elements of social capital affect subjective wellbeing. We also explore the interplay between trust and social networks. Existing literature suggests that trust and social networks positively impact wellbeing, with one strand of the literature suggesting that in developed countries social capital is a stronger determinant of wellbeing than income. However, we find that this is not the case for China (a developing country) where the effects of trust and social networks on wellbeing are found to be relatively weaker compared to the effect of income.     

Study on lumbar kinematics and the risk of low back disorder in female university students by using shoes of different heel heights

The study was taken up to investigate the effects of heel heights on lumbar kinematics and the risk of Low Back Disorder (LBD) in females. Nineteen female university students (24.5 ± 3.36 yrs) volunteered in the study. Lumbar kinematics was measured by using Industrial Lumbar Motion Monitor (iLMM). The volunteers were asked to walk for a distance of 50 meters in 3 different given conditions i.e bare foot (Heel 0), with flat heels (Heel 1) and with high heels (Heel 2). Heights of Heel 1 and Heel 2 were 1.5 ± 0.84 cm and 5.5 ± 1.70 cm respectively. The Lumbar kinematic parameters studied were- Average Twisting Velocity (ATV), Maximum Sagital Flexion (MSF) and Maximum Lateral Velocity (MLV). It was observed that all the above mentioned Lumbar kinematics - ATV, MSF and MLV increases with increase of heel heights, which in turn increases the risk of LBD. As a result of increase in Lumbar kinematic values with increase in heel heights, LBD risk has also increased. Mean and SD of the LBD risk with Heel 0, Heel 1 and Heel 2 were 16.79 ± 6.04%, 19.00 ± 7.38% and 22.11 ± 6.98% respectively. Lower stature with high heels showed higher risk of LBD than the higher stature with high heels.     

Demand Forecast Sharing in Supply Chains

This paper examines the incentives of a manufacturer and a retailer to share their demand forecasts. The demand at the retailer is a linearly decreasing function of price. The manufacturer sets the wholesale price first, and the retailer sets the retail price after observing the wholesale price. Both players set their prices based on their forecasts of demand. In the make‐to‐order scenario, the manufacturer sets the production quantity after observing the actual demand; in the make‐to‐stock scenario, the manufacturer sets the production quantity before the demand is realized. In the make‐to‐order scenario, we show that sharing the forecast unconditionally by the retailer with the manufacturer benefits the manufacturer but hurts the retailer. We also demonstrate that a side payment contract cannot induce Pareto‐optimal information sharing equilibrium, but a discount based wholesale price contract can. The social welfare as well as consumer surplus is higher under the discount contract, compared with under no information sharing. In the make‐to‐stock scenario, the manufacturer realizes additional benefits in the form of savings in inventory holding and shortage costs when forecasts are shared. If the savings from inventory holding and shortage costs because of information sharing are sufficiently high, then a side payment contract that induces Pareto‐optimal information sharing is feasible in the make‐to‐stock scenario. We also provide additional managerial insights with the help of a computational study.     

Risk and protective factors in problem gambling: an examination of psychological resilience

Psychological resilience – successful adaptation when faced with adversity – is a product of the balance of risk and protective factors relevant to an outcome. This study examined if protective factors (perceived resilience; mindfulness; grit; self-efficacy) explained variance in problem gambling tendencies (assessed with the Problem Gambling Severity Index) beyond the HEXACO personality traits (honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, openness to experience) and risk factors for problem gambling (gender; age; socio-economic status; high frequency gambling behaviour; harsh unpredictable childhood environments; sensation-seeking; impulsivity; self-control; stress). This study used a crowdsourced community sample (n = 469) recruited from Amazon Mechanical Turk. Bivariate analyses showed that risk factors and some HEXACO traits (especially honesty-humility) were associated with problem gambling issues. Among protective factors, only trait mindfulness showed a bivariate association with problem gambling issues. Somewhat surprisingly, regression analyses revealed that protective factors did not explain variance in problem gambling beyond HEXACO traits and risk factors. However, in exploratory analyses, mindfulness and self-efficacy – both modifiable protective factors – moderated the relationship between high-frequency gambling (a key proximate antecedent of problem gambling) and problem gambling tendencies. These results suggest mindfulness and self-efficacy may serve as ‘buffers’ against the development of problem gambling issues and may be promising targets for clinical interventions.     

Characteristics for the Effectiveness of Women’s Self-Help Groups in Bihar

This study examines whether group heterogeneity and group structure and process predict the effectiveness of women’s self-help groups in terms of their financial performance, self-reliance of the group, members’ decision-making ability at the household level, and access to non-financial benefits. Data were collected using an interview schedule from 210 women’s self-help groups in six districts of Bihar and data were analyzed using partial least squares structural equation modeling. The findings suggest that the group heterogeneity directly predicts the effectiveness of women’s self-help groups and it is fully transmitted through group structure and process to positively predict the effectiveness of the women’s self-help groups. The group structure and process is found to be a full mediator between group heterogeneity and group effectiveness. The predictive accuracy of the model is found to be high. The findings have implications to bring in more diversity in members castes, education, and their reasons for joining women’s self-help groups at the formation stage and variations in members’ skills and expertise at the performing stage of the groups. The members’ awareness on group norms and trust in financial transactions, and leadership styles together with cooperation and cohesion among members, transparency in financial transactions, group attendance, and networking with the bank and the federation foster the effectiveness of women’s self-help groups.     

Exploring the Urban–Rural Incarceration Divide: Drivers of Local Jail Incarceration Rates in the United States

ABSTRACT

A large body of research has focused on understanding mass incarceration in the United States through the lens of federal and state prison growth. However, local jail systems, with 11 million admissions each year, have received less research attention despite their broad impact on communities. Preliminary analysis conducted by the Vera Institute of Justice (Vera) uncovered geographical disparities in county jail incarceration rates. Contrary to assumptions that incarceration is an urban phenomenon, Vera discovered that, in recent decades, pretrial jail rates have declined or remained flat in many urban areas, whereas rates have grown in rural counties. In an effort to uncover factors contributing to continued jail growth in rural areas, Vera joined forces with Two Sigma’s Data Clinic, a volunteer-based program that leverages Two Sigma employees’ data science expertise. Determinants of local jail rates from 2000–2013 were examined using a generalized estimating equations (GEE) model to account for correlations within counties over time. Results revealed that county-level poverty, police expenditures, and spillover effects from other county and state authorities are significant predictors of local jail rates. Investigation of model residuals revealed clusters of counties where observed rates were much higher than expected conditioned upon county variables.     

The Measurement of Socio-Economic Status: Investigation of Gender-and Age-Specific Indicators in Australia: National Health Survey 1995

Objective: To investigate thecorrelations between age- and gender-specificmeasures of socio-economic status versus healthstatus as measured by the SF-36. Design: Population based study. Participants: 38187 people aged between18 to 79 years who participated in the NationalHealth Survey in 1995. Results: Factor analysis producedconsistent results that were interpreted interms of five conceptually meaningful domains(employment, housing, migration, family unitand education). The relative rank of thefactors differs between groups and in somecases factor composition requires items to beadded or deleted from the conceptual domains. Conclusions: Age- and gender-specific SESscores based on these factors had strongerassociations with the physical and mentalcomponents of SF-36 than either an area basedindex or scores derived from males aged 40–44years. Overall the results supported thehypothesis that SES measures composed of socialand demographic items exhibit important age-and gender-specific differences which arerelevant for health.
