The impact of mothers’ earnings on health inputs and infant health

This paper investigates the impact of mothers’ earnings on birth weight and gestational age of infants in the U.S. It also analyzes the impact of earnings on mothers’ consumption of prenatal medical care, and their propensity to smoke and drink during pregnancy. The paper uses census division-year-specific skill-biased technology shocks as an instrument for mothers’ earnings and employs a two-sample instrumental variables strategy. About 14 million records of births between 1989 and 2004 are used from the Natality Detail files along with the CPS Annual Demographic Files from the same period. The results reveal that an increase in weekly earnings prompts an increase in prenatal care of low-skill mothers (those who have at most a high school degree) who are not likely to be on Medicaid, and that earnings have a small positive impact on birth weight and gestational age of the newborns of these mothers. Specifically, if a mother's earnings double, this produces a weight gain of the newborn by about 100 g and an increase in gestational age by 0.7 weeks. An increase in earnings does not influence the health of newborns of high-skill mothers (those with at least some college education). Variations in earnings have no impact on birth weight for mothers who are likely to be on Medicaid.     

The impact of heat waves on children’s health: a systematic review

Young children are thought to be particularly sensitive to heat waves, but relatively less research attention has been paid to this field to date. A systematic review was conducted to elucidate the relationship between heat waves and children’s health. Literature published up to August 2012 were identified using the following MeSH terms and keywords: “heatwave”, “heat wave”, “child health”, “morbidity”, “hospital admission”, “emergency department visit”, “family practice”, “primary health care”, “death” and “mortality”. Of the 628 publications identified, 12 met the selection criteria. The existing literature does not consistently suggest that mortality among children increases significantly during heat waves, even though infants were associated with more heat-related deaths. Exposure to heat waves in the perinatal period may pose a threat to children’s health. Pediatric diseases or conditions associated with heat waves include renal disease, respiratory disease, electrolyte imbalance and fever. Future research should focus on how to develop a consistent definition of a heat wave from a children’s health perspective, identifying the best measure of children’s exposure to heat waves, exploring sensitive outcome measures to quantify the impact of heat waves on children, evaluating the possible impacts of heat waves on children’s birth outcomes, and understanding the differences in vulnerability to heat waves among children of different ages and from different income countries. Projection of the children’s disease burden caused by heat waves under climate change scenarios, and development of effective heat wave mitigation and adaptation strategies that incorporate other child protective health measures, are also strongly recommended.     

Parental nonemployment in childhood and children’s health later in life

While the effects of joblessness on the health of the non-employed are well-documented, its long-term spillover consequences on the health of their relatives, especially children, remain poorly understood. This research explores the long-term associations of parental nonemployment spells experienced during early, mid and late childhood on children’s mental and physical health. The analysis exploits data drawn from the British Household Panel Survey (BHPS) and the UK Household Longitudinal Study (UKHLS), linking detailed parental socioeconomic information with their children between the years 1993 and 2013. This paper employs a Correlated Random Effects (CRE) probit model that allows accounting for unobserved heterogeneity as well as a non-linear Generalized Estimating Equations (GEE) random effects estimator accounting in addition for the dependency structure of the data. Results indicate that experiencing parental nonemployment during early and late childhood has a negative association on the children’s likelihood of suffering from long-standing illnesses later in life, while experiencing parental nonemployment during middle childhood negatively affects the young adult’s mental health. Moreover, experiencing parental nonemployment during late childhood increases the probability of both reporting poor or fair self-assessed health and the likelihood of consuming prescribed medicines in early adulthood. However, there seems to be a considerable effect heterogeneity by family socioeconomic status, parents’ gender, and frequencies of parental nonemployment spells. Current adulthood circumstances, such as level of educational attainment, job situation and household demographics, are used to explore the potential mechanisms affecting results. These findings may help policymakers shape appropriate responses to mitigate the psychological and physical burden derived from parental nonemployment, especially among already disadvantaged households.

Studying the impact of the Eurozone’s Great Recession on health: Methodological choices and challenges

Europe’s Great Recession provides an opportunity to study the impact of increased financial insecurity on health. A number of studies explored the impact of the Recession on health, but they often reached different conclusions. To understand the root of this debate, we undertook a systematic literature review. Articles were analysed thematically based on: geography, data type, operationalisations of wealth and health, and study design. A critical appraisal was also undertaken. Forty-two studies, published from January 2010 to October 2018, were included in our review. Twenty-six of the forty-two studies found that the Great Recession worsened physical health indicators in the Eurozone. In terms of geography, a large concentration of studies focussed on Spain and Greece, indicating that there may be a gap in understanding the health consequences for EU countries with less severe experiences of the Recession. Regarding data type, nearly all studies used secondary datasets, possibly meaning that studies were constrained by the data available. In terms of operationalisations of wealth and health, a majority of studies used single/simple measures of both, so that these multi-faceted concepts were not fully reflected. Further, fewer than half included studies used panel data, with the remaining studies unable to undertake more causal analyses. The results of the critical appraisal showed that lower-quality studies tended to not find a negative impact of the Recession on health, whereas higher quality studies generally did. In future, we recommend conducting cross-country comparisons, using (inter)nationally-representative panel data conducted over a minimum of a ten-year time horizon, and employing multi-faceted operationalisations of wealth and health. This could provide more common ground across studies, and a clearer indication of whether the Recession impacted health.     

The impact of shift starting time on sleep duration,sleep quality,and alertness prior to injury in the People’s Republic of China

Early shift start time and night shifts are associated with reduced sleep duration and poor sleep quality that often lead to increased fatigue levels, performance decrements and adverse safety and health outcomes. This study investigates the impact of shift starting time on sleep patterns, including the duration and quality of sleep and alertness/sleepiness at the time of injury, in a large epidemiological field study of hospitalized adults with severe work-related hand injury in the People’s Republic of China (PRC) from multiple industries with severe work-related traumatic hand injury were recruited from 11 hospitals in three industrially-developed cities in the PRC: Ningbo, Liuzhou and Wuxi. Analysis of covariance (ANCOVA) was used to compare sleep duration, sleep quality and alertness/sleepiness across 3?h increments of shift start time, while adjusting for age, gender, work hours, shift duration, day of injury and several transient work-related factors. Effect modification by gender was also evaluated. Seven-hundred and three hospitalized adults (96.4%) completed a face-to-face interview within 4 days of injury; 527 (75.0%) were male, with a mean (±SEM) age of 31.8?±?0.4 years. Overall, these adults worked relatively long weekly (55.7?±?0.6?h) and daily hours (8.6?±?0.07?h). Average sleep duration prior to injury was 8.5?h (±0.07), and showed significant variations (p value <0.05) across shift starting time increments. Overall mean prior sleep duration was shortest for individuals starting shifts from “21:00–23:59” (5.6±0.8?h) followed by midnight “00:00–02:59” (6.1?±?0.6?h). However, a statistically significant interaction (p?<?0.05) was observed between gender and shift starting time on mean sleep duration. For males the shortest sleep duration was 5.6?h (“21:00–23:59”) and for females the shortest was 4.3?h (“24:00–02:59” and “15:00–17:59”). Sleep quality (generally quite well) and alertness/sleepiness based on the KSS (generally alert) did not vary significantly across shift starting time. Results suggest that sleep duration is shortest among injured PRC adults starting shifts late night and early morning. However, with more than 8.5?h of sleep on average work days, Chinese slept much longer than typical US day workers (Sleep in America Poll, 2012, 6:44 on workdays, 7:35 on free days), and this may help to explain higher than expected alertness/sleepiness scores at the time of injury.

The impact of time of day on the gait and balance control of Alzheimer’s patients

Alzheimer’s patients suffer from circadian dysregulation. The aim of this study was to examine the evolution of balance control and gait at different times of the day (11:00, 14:00, 18:00) in order to identify whether Alzheimer’s patients were more likely to fall at certain periods of the day. Spatio-temporal parameters of centre of foot pressure displacements were measured with a force platform and spatio-temporal parameters of walking were evaluated with a gait analysis device. The results highlighted that balance control was worse in the evening and the afternoon than in the morning. Furthermore, the walking speed was faster and support duration, swing duration and cycle duration were shorter in the evening than in the morning and afternoon. The combined analysis of balance control and gait parameters revealed that balance control and walking are concomitantly altered in the evening which increases the fall risk in the evening, in comparison with the morning, for Alzheimer’s patients.     

Sustainable Forestry and Local People: The Case of Hainan’s Li Minority

On the island of Hainan, China, the provincial government has recently committed itself to sustainable development, which requires the integration of social, environmental, and economic factors in decision making. However, while Hainan’s recent Eco-province designation establishes environmental and economic factors as the basis of policy development, it overlooks the equally important social component of sustainability, in which social needs and values are key considerations. This paper presents the results of a study on Hainan in 2002, with government officials, forestry workers, and the Li, an indigenous minority group, and places the province’s situation within the context of both the larger changes underway in China, and the theory and practice of sustainable forestry. The research results show that the government of Hainan has not yet been able to manage both social welfare and environmental and economic issues, demonstrating the difficulty of implementing sustainable forestry and of balancing short- with long-term goals. The inclusion of Li communities in forestry-related decision making could reduce tensions between local communities and forestry management and also improve the sustainability of the government’s forestry practices.

The impact of gout on patient’s lives: a study of African-American and Caucasian men and women with gout

Introduction

The aim of this study was to examine the impact of gout on quality of life (QOL) and study differences by gender and race.

Methods

Ten race- and sex-stratified nominal groups were conducted, oversampling for African-Americans and women with gout. Patients presented, discussed, combined and rank-ordered their concerns.

Results

A total of 62 patients with mean age 65.1 years, 60% men, 64% African-American, participated in 10 nominal groups: African-American men (n = 23; 3 groups); African-American women (n = 18; 3 groups); Caucasian men (n = 15; 3 groups); and Caucasian women (n = 6; 1 group). The most frequently cited high-ranked concerns among the ten nominal groups were: (1) effect of gout flare on daily activities (n = 10 groups); (2) work disability (n = 8 groups); (3) severe pain (n = 8 groups); (4) joint swelling and tenderness (n = 6 groups); (5) food restrictions (n = 6 groups); (6) medication related issues (n = 6 groups); (7) dependency on family and others (n = 5 groups); (8) emotional Impact (n = 5 groups); (9) interference with sexual function (n = 4 groups); (10) difficulty with shoes (n = 4 groups); and (11) sleep disruption (n = 4 groups). Compared with men, women ranked the following concerns high more often: problems with shoes (n = 4 versus n = 0 groups); dependency (n = 3 versus n = 2 groups); and joint/limb deformity (n = 2 versus n = 0 group). Compared with Caucasians, African-Americans ranked the following concerns high more often: dietary restrictions (n = 6 versus n = 0 groups); severe pain (n = 6 versus n = 2 groups); gout bringing the day to a “halt” (n = 2 versus n = 0 group); effect on emotional health (n = 4 versus n = 1 groups); and the need for canes/crutches during flares (n = 2 versus n = 0 group).

Conclusions

Gout has a significant impact on a patient’s QOL. Important differences in the impact of gout by gender and race were noted.     

The rhetoric of Islamophobia: an analysis of the means of persuasion in Hege Storhaug’s writings on Islam and Muslims

Few actors have had a greater impact on the “framing of Muslims” as a social and political “problem” in Norway since 2001 than Hege Storhaug of the government- and corporate billionaire funded civil society organization Human Rights Service (HRS). Using the methodological tools of the “rhetorical branch” of Critical Discourse Analysis (CDA), and applying the Aristotelian concepts of ethos, logos and pathos, we analyze the bestselling popular title on Islam and Muslims ever published in Norway, namely Storhaug’s self-published 2015 title “Islam – The Eleventh Plague”. We argue that Storhaug’s popular success must be understood in light of her rhetorical appeals to femonationalism, the critique of religion and “Enlightenment” values. We show how she in her writings incites fear of the Muslim “Other” through specific rhetorical devices and a positioning of herself as a defender of the “nation” and the “people” – against national and international “elites”.     

The long-run effects of adolescent athletic participation on women’s health

Increased athletic opportunities have been shown to improve educational and labor force outcomes, however few studies have linked athletic participation to health later in life. We use the implementation of Title IX, legislation banning gender discrimination in educational programs in the U.S., to estimate the effect of increased access to high school athletic opportunities on women’s later life health. Our results indicate that increased participation leads to fewer days in poor mental health, reduced BMI and rates of obesity, lower smoking rates, and some evidence of a reduced likelihood of a diabetes diagnosis. However, we find no impact of high school athletic participation on the number of days in poor physical health and current exercise, and a positive relationship between participation and alcohol consumption.     

Michael Parker Banton: an appreciation of his life’s work

This article is an appreciation of the contributions to ethnic and racial studies and to British sociology in general of Michael Parker Banton. It reviews his career and also his major publications, including also arguments against him made by his principal critics and his responses to these. It points out the specificity of his contributions and argues for his unique importance in defining and developing the field of ethnic and race relations in British sociology during the second half of the twentieth century and into the present century. It also mentions his many contributions to public life.     

Assessing the impact of fostering on children’s outcomes in Niger

This article measures the impact of fostering on children’s outcomes in Niger. We estimate a simultaneous equations model with three outcomes for children (school attendance, hours of market work and hours of domestic work) and a treatment variable (fostering). Nonlinearity provides identification by functional form of the causal effect of fostering. We further use information on the historical level of community integration of the child’s ethnicity and the relative importance of the ethnicity in the neighborhood to build a plausibly exogenous exclusion restriction in order to correct for the potential endogeneity of fostering. Our results sustain the overall conclusion that fostering has a positive impact on children’s school attendance and hours of domestic work. However, while foster boys and girls are both engaged in longer hours of domestic labor, only foster boys are advantaged in terms of schooling.     

Effects of Textured Insoles on Balance in People with Parkinson’s Disease

Background

Degradation of the somatosensory system has been implicated in postural instability and increased falls risk for older people and Parkinson’s disease (PD) patients. Here we demonstrate that textured insoles provide a passive intervention that is an inexpensive and accessible means to enhance the somatosensory input from the plantar surface of the feet.

Methods

20 healthy older adults (controls) and 20 participants with PD were recruited for the study. We evaluated effects of manipulating somatosensory information from the plantar surface of the feet using textured insoles. Participants performed standing tests, on two different surfaces (firm and foam), under three footwear conditions: 1) barefoot; 2) smooth insoles; and 3) textured insoles. Standing balance was evaluated using a force plate yielding data on the range of anterior-posterior and medial-lateral sway, as well as standard deviations for anterior-posterior and medial-lateral sway.

Results

On the firm surface with eyes open both the smooth and textured insoles reduced medial-lateral sway in the PD group to a similar level as the controls. Only the textured insole decreased medial-lateral sway and medial-lateral sway standard deviation in the PD group on both surfaces, with and without visual input. Greatest benefits were observed in the PD group while wearing the textured insoles, and when standing on the foam surface with eyes closed.

Conclusions

Data suggested that textured insoles may provide a low-cost means of improving postural stability in high falls-risk groups, such as people with PD.     

Morris Goodman’s hominoid rate slowdown: The importance of being neutral

Half a century ago, when the field of molecular evolution did not even exist, Morris Goodman analyzed profiles of immunological interactions between species and reached the following two remarkable conclusions: first, protein evolution slowed down in the human lineage compared to other primate lineages; second, this slowdown was more pronounced for proteins whose functions were likely to be neutral. It took several decades of research to fully grasp these ideas and document the pattern of hominoid rate slowdown. Along the way, studies of hominoid rate slowdown led to major progresses in understanding determinants of neutral molecular evolution, which in turn is used to calibrate rates of adaptive evolution. Furthermore, the growing knowledge on the origin of mutations provides a basis for understanding differential evolutionary rates between sex chromosomes and autosomes, which has deep implications for inferring human evolutionary histories, and other aspects of molecular evolution. Primate genomics in particular stand to provide critical information in these pursuits, due to the abundance of genomic data, relatively rich documentation of life history traits, and several model systems, including our own species.     

The Prevalence and Implications of Human–Animal Co-Sleeping in an Australian Sample

Sleep research is characterized by an interest in humans, with the realm of animal sleep left largely to ethologists and animal scientists. However, the lives of sleep-study participants and those with sleep problems frequently involve animals. For the majority of the population in developed countries who own pets, their waking lives are impacted by the duties of animal care and ownership. For many, their sleeping lives are also impacted through sharing their bedrooms or their beds with pets. Yet, little is known about the prevalence of human–animal co-sleeping relationships or their impact on sleep. The aim of this study was to determine the prevalence and implications of human–animal co-sleeping in an Australian sample. The study uses data collected from the 2012 Sealy Sleep Census, a national online survey of sleep wellness that included a sample of 10,128 after data cleaning. The population of respondents (aged 18–74) who co-slept with pets (n = 1,018 or 10% of the sample) was then matched to a sample of respondents who did not co-sleep with pets, according to gender and age. Those who co-slept with pets took longer to fall asleep (p = 0.029), were more likely to wake up tired (p = 0.025), and although they were not more likely to wake up due to a disturbance, those who did had a greater chance of being disturbed by dog barking/animals making noises (p < 0.001). However, there were no significant differences found in total self-reported sleep length or feelings of tiredness during the day. The continued practice of co-sleeping with pets suggests that there may be some benefits such as social support and social interaction, and increased feelings of personal security. The survey provides a preliminary understanding of the prevalence and implications of human–animal co-sleeping, and highlights areas for further examination of its implications on sleep research and clinical practice.     

Too unwell to trust? The effect of mental health on social trust in Europe

Social trust is often thought to be adversely affected by mental health problems. However, rigorous causal evidence required to substantiate this thought is scarce. Here I examine the causal effect of individuals’ mental health on social trust using data from the European Social Survey. Estimating the causal effect, however, is a formidable task since the relationship between mental health and social trust is endogenous due to reverse causality and unmeasured confounding. I circumvent these difficulties by using a recently developed econometric technique that does not rely on valid exclusion restriction for identification. I find strong evidence that mental ill health has a significant negative effect on social trust. Further, I provide suggestive evidence which shows that the adverse effect of mental ill health on social trust arises due to reductions in individuals’ level of optimism and hope, and participation in social networks caused by mental ill health. Overall, the results suggest that for achieving a durable increase in social trust – which often is one of the fundamental objectives of policy makers – interventions to promote mental health of individuals could be extremely useful.     

The impact of Ivan Málek’s continuous culture concept on bioprocessing

This paper summarizes research results and their industrial applications obtained by continuous culture in the former Czechoslovakia. Past achievements as well as recent trends and developments worldwide are presented. The term “Prague School of continuous culture” is put forward and its international activity is outlined. The impact of this school was pervasive across the entire field of applied microbiology and biotechnology in Czechoslovakia and, perhaps, even beyond the country's boarders. Continuous culture is a very mature field, and since its establishment it has become a powerful research tool. The present activity in this field amounts to a renaissance of continuous culture, emphasizing new dimensions in bioinformatics and systems biology.
