Selection and the Marriage Premium for Infant Health
Authors: Buckles Kasey S. , Price Joseph 
Published: April 2013

AbstractPrevious research has found a positive relationship between marriage and infant health, but it is unclear whether this relationship is causal or a reflection of positive selection into marriage. We use multiple empirical approaches to address this issue. First, using a technique developed by Gelbach (2009) to determine the relative importance of observable characteristics, we show how selection into marriage has changed over time. Second, we construct a matched sample of children born to the same mother and apply panel data techniques to account for time-invariant unobserved characteristics. We find evidence of a sizable marriage premium. However, this premium fell by more than 40 % between 1989 and 2004, largely as a result of declining selection into marriage by race. Accounting for selection reduces ordinary least squares estimates of the marriage premiums for birth weight, prematurity, and infant mortality by at least one-half.
Causal beliefs of the public and social acceptance of persons with mental illness: a comparative analysis of schizophrenia, depression and alcohol dependence
Authors: Schomerus G. , Matschinger H. , Angermeyer M. C. 
Published: April 2013

BackgroundThere is an ongoing debate whether biological illness explanations improve tolerance towards persons with mental illness or not. Several theoretical models have been proposed to predict the relationship between causal beliefs and social acceptance. This study uses path models to compare different theoretical predictions regarding attitudes towards persons with schizophrenia, depression and alcohol dependence.MethodIn a representative population survey in Germany (n = 3642), we elicited agreement with belief in biogenetic causes, current stress and childhood adversities as causes of either disorder as described in an unlabelled case vignette. We further elicited potentially mediating attitudes related to different theories about the consequences of biogenetic causal beliefs (attribution theory: onset responsibility, offset responsibility; genetic essentialism: differentness, dangerousness; genetic optimism: treatability) and social acceptance. For each vignette condition, we calculated a multiple mediator path model containing all variables.ResultsBiogenetic beliefs were associated with lower social acceptance in schizophrenia and depression, and with higher acceptance in alcohol dependence. In schizophrenia and depression, perceived differentness and dangerousness mediated the largest indirect effects, the consequences of biogenetic causal explanations thus being in accordance with the predictions of genetic essentialism. Psychosocial causal beliefs had differential effects: belief in current stress as a cause was associated with higher acceptance in schizophrenia, while belief in childhood adversities resulted in lower acceptance of a person with depression.ConclusionsBiological causal explanations seem beneficial in alcohol dependence, but harmful in schizophrenia and depression. The negative correlates of believing in childhood adversities as a cause of depression merit further exploration.
‘Keeping going’: chronic joint pain in older people who describe their health as good
Authors: RICHARDSON JANE C. , GRIME JANET C. , ONG BIE NIO 
Published: April 2013

ABSTRACTIt is common for people with chronic conditions to report their health as good, although models of healthy ageing do not account for this. The concept of successful ageing focuses on overcoming problems, in contrast to the concept of resilience, which can acknowledge vulnerability. Osteoarthritis (OA) is the main cause of joint pain in older people, but research in this area has tended to focus on OA as an illness. Consequently, our research aimed to explore OA from the perspective of wellness. We undertook a longitudinal qualitative study to explore ‘wellness and resilience’ in a group of older people who reported chronic joint pain and considered themselves healthy. We interviewed 27 people and followed them up with monthly diary sheets, responding to reports of changes using their chosen contact method. This article focuses on how resilience relates to how people consider themselves to be well. Participants' experience of the adversity of their pain varied, and was influenced by context and meaning. Participants described ‘keeping going’ in body, mind and everyday life. Flexibility and pragmatism were key aspects of keeping going. The findings support a broader version of resilience that incorporates vulnerabilities. In the context of health care we suggest that treating the frail body should not come at the expense of undermining an older person's sense of a resilient self.

AbstractIntroduction:On 28 November 2002, three suicide bombers crashed their car into a hotel in Mombassa, Kenya; 12 people were killed, including three Israelis, and 80 were wounded (22 of whom were Israeli). The Israeli Defense Force Airborne Medical Evacuation Flight Teams participated in a repatriation mission to bring the wounded home.Objectives:The objectives of this study are to outline the distinctive aspects of this mission, as well as to share the experiences and lessons learned.Methods:Israeli Army debriefing reports were used to study the composition of the crew, medical equipment taken, injury distribution, mode of operation, and mission schedule.Results:A total of six fixed-wing aircraft were used—two Boeing 707s and four Hercules C-130s—with a total of 54 medical team members on board. A total of 260 Israelis were repatriated, 22 of whom were wounded, and three were dead. Of the casualties, 14 were conveyed sitting, and eight supine. The time from the first landing in Kenya to the evacuation of the last supine patient was 5.5 hours. Nurses, as well as social workers, played a central role in the mission. A forward team, including five doctors, was used for the initial organization and for gathering information on the medical status of the casualties.Conclusions:There was redundancy in the medical crew and medical equipment sent. The need for improved infrastructure on the medical aircraft was stressed. Based on this experience, a new mode for operation for similar missions in the future was formulated.
A hard row to hoe: farming on the economic frontier under incomplete property rights
Authors: Tatum Robert C. 
Published: April 2013

AbstractFarmers on the economic frontier often do not have clear titles to their land. Therefore, using an infinite-horizon representative agent model calibrated with data for the Brazilian Amazon, this paper analyzes how improved property rights influence the frontier farmer's investment in the land, as well as the farmer's consumption and debt. Three channels through which property rights affect these variables are identified in the analysis. Two involve the expenditure the farmer incurs to defend the land claim, and the third involves the interest rate premium the farmer faces when borrowing without a clear title to the land. Variants of the model allow for labor to defend the land claim and for endogenous property rights. The findings suggest a need and direction for further, empirical research, particularly with regard to informal institutional arrangements, measures of property rights and the means by which they are defended.

Published: April 2013

ABSTRACTContext:A disaster is indiscriminate in whom it affects. Limited research has shown that the poor and medically underserved, especially in rural areas, bear an inequitable amount of the burden.Objective:To review the literature on the combined effects of a disaster and living in an area with existing health or health care disparities on a community's health, access to health resources, and quality of life.Methods:We performed a systematic literature review using the following search terms: disaster, health disparities, health care disparities, medically underserved, and rural. Our inclusion criteria were peer-reviewed, US studies that discussed the delayed or persistent health effects of disasters in medically underserved areas.Results:There has been extensive research published on disasters, health disparities, health care disparities, and medically underserved populations individually, but not collectively.Conclusions:The current literature does not capture the strain of health and health care disparities before and after a disaster in medically underserved communities. Future disaster studies and policies should account for differences in health profiles and access to care before and after a disaster.(Disaster Med Public Health Preparedness. 2010;4:30-38)

Published: April 2013

ABSTRACTObjectives: To identify health care workers most at risk for H1N1 infection before vaccination and compare health outcomes after vaccination.Methods: The indices used to gauge employee health were laboratory-confirmed H1N1 data, laboratory-confirmed influenza A data, and employee sick hours records. In phase 1 of this 2-phase study, absenteeism records for 6,093 hospital employees before vaccine administration were analyzed according to department and employee position during the spring 2009 H1N1 pandemic.Results: Records of 123 confirmed reports of laboratory-confirmed influenza A or novel H1N1 infections in hospital employees were also analyzed. Two thirds of the H1N1 cases occurred during June (infection rates in parentheses): 34 in physicians and medical personnel (6.7%), 36 in nurses and clinical technicians (2.2%), 39 in Administrative & Support Personnel (infection rate = 1.2%), 3 in Social Workers & Counselors (infection rate = 1.0%), 8 in Housekeeping & Food Services (infection rate = 2.7%), and 3 in Security & Transportation (infection rate=3.9%). When analyzed according to department, the adult emergency department (infection rate = 28.8%) and the pediatric emergency department (infection rate = 25.0%) had the highest infection rates per department.Conclusions: Of the reported cases of H1N1 in health care workers, 49% occurred in a population that constitutes less than 20% of the total population studied. Physicians and medical personnel had a higher infection rate than other employee positions, whereas ED personnel had the highest infection rate.(Disaster Med Public Health Preparedness. 2010;4:47-54)
Involvement of the US Department of Defense in Civilian Assistance, Part I: A Quantitative Description of the Projects Funded by the Overseas Humanitarian, Disaster, and Civic Aid Program

Published: April 2013

ABSTRACTObjectives:To review the history and goals of the US Department of Defense's largest civilian assistance program, the Overseas Humanitarian, Disaster and Civic Aid Program and to describe the number, geographic regions, years, key words, countries, and types of projects carried out under this program since 2001.Methods:Using the program's central database, we reviewed all approved projects since 2001 and tabulated them by year, combatant command, country, and key word. We also reviewed the project descriptions of projects funded between January 1, 2006, and February 9, 2008, and examined how their activities varied by combatant command and year.Results:Of the 5395 projects in the database, 2097 were funded. Projects took place in more than 90 countries, with Southern, Pacific, and Africa Command hosting the greatest number. The most common types of projects were school, health, disaster response, and water infrastructure construction, and disaster-response training. The “global war on terror” was the key word most frequently tagged to project descriptions. Project descriptions lacked stated goals as well as implementation and coordination strategies with potential partners, and did not report outcome or impact indicators.Conclusion:The geographic reach of the program is vast and projects take place in a wide variety of public sectors. Yet their security and civilian assistance value remains unclear given the lack of stated project goals, implementation strategies, or measures of effectiveness. To facilitate transparency and policy discussion, we recommend project proposals include hypotheses as to how they will enhance US security, their relevance to the public sector they address, and outcome and impact indicators that can assess their value and effectiveness.(Disaster Med Public Health Preparedness. 2010;4:66-73)
Sea-Level-Rise Disaster in Micronesia: Sentinel Event for Climate Change?
Authors: Keim Mark E. 
Published: April 2013

ABSTRACTObjectives: To describe the impact of an acute-onset sea-level-rise disaster in 2 coral atoll populations and to generate hypotheses for further investigation of the association between climate change and public health.Methods: Households of Lukunoch and Oneop islands, Micronesia, were assessed for demographics, asset damage, food availability, water quantity and quality, hygiene and sanitation, and health status. Every fourth household on Lukunoch was randomly selected (n = 40). All Oneop households were surveyed (n = 72). Heads of each household were interviewed in the local language using a standard survey tool. Prevalence data were analyzed, and 95% confidence intervals were calculated.Results: A total of 112 total households were respondents representing 974 inhabitants. On Lukunoch, roughly half of all households surveyed reported at least a partial loss of their primary dietary staple and source of calories (taro and breadfruit). Six (15%) of 40 Lukunoch households surveyed (95% CI, 6%-30%) reported a complete loss of taro and four (10%) of the 40 households (95% CI, 3%-24%) reported a complete loss of breadfruit. On Oneop, nearly all households reported at least a partial loss of these same food staples. Twenty four (31%) of all 76 Oneop households reported a complete loss of taro and another 24 (31%) households reported a complete loss of breadfruit. One third of all households surveyed reported a complete loss. On Lukunoch 11 (28%) of 40 households, (95% CI, 15%-43%) reported damage from salination, but none were damaged to the point of a complete loss. Forty-nine (64%) of 76 Oneop households reported salination and five (6%) reported complete loss of their well.Conclusion: On March 5, 2007, an acute-onset, sea level rise event resulting in coastal erosion, shoreline inundation, and saltwater intrusion occurred in two coral atoll islands of Micronesia. The findings of this study suggest that highly vulnerable populations of both islands experienced disastrous losses involving crop productivity and freshwater sources. These findings reveal the need for effective public health research and sustainable interventions that will monitor and shape the health of small island populations predicted to be at high risk for adverse health effects due to climate change.(Disaster Med Public Health Preparedness. 2010;4:81-87)

Abstract
Desulfovibrio vulgaris Hildenborough strains with significantly increased tolerance to NaCl were obtained via experimental evolution. A NaCl-evolved strain, ES9-11, isolated from a population cultured for 1200 generations in medium amended with 100 mm NaCl, showed better tolerance to NaCl than a control strain, EC3-10, cultured for 1200 generations in parallel but without NaCl amendment in medium. To understand the NaCl adaptation mechanism in ES9-11, we analyzed the transcriptional, metabolite and phospholipid fatty acid (PLFA) profiles of strain ES9-11 with 0, 100- or 250 mm-added NaCl in medium compared with the ancestral strain and EC3-10 as controls. In all the culture conditions, increased expressions of genes involved in amino-acid synthesis and transport, energy production, cation efflux and decreased expression of flagellar assembly genes were detected in ES9-11. Consistently, increased abundances of organic solutes and decreased cell motility were observed in ES9-11. Glutamate appears to be the most important osmoprotectant in D. vulgaris under NaCl stress, whereas, other organic solutes such as glutamine, glycine and glycine betaine might contribute to NaCl tolerance under low NaCl concentration only. Unsaturation indices of PLFA significantly increased in ES9-11. Branched unsaturated PLFAs i17:1 ω9c, a17:1 ω9c and branched saturated i15:0 might have important roles in maintaining proper membrane fluidity under NaCl stress. Taken together, these data suggest that the accumulation of osmolytes, increased membrane fluidity, decreased cell motility and possibly an increased exclusion of Na+ contribute to increased NaCl tolerance in NaCl-evolved D. vulgaris.

Published: April 2013

Background: Psychotic symptoms are common among cocaine users. Methods: An observational naturalistic study on the effects and events of intravenous cocaine use in a drug consumption room was carried out; the patients were diagnosed of cocaine dependence (according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision). Results: Twenty-one patients, 81% men self-injected cocaine 375 times. Psychotic symptoms were observed in 62% of the patients and 21% of the self-injections; delusions were observed in 9.3%, psychotic self-reference with insight in 9.1%, illusions in 6.4%, and hallucinations in 5.3%. A higher presence of psychotic symptoms was noted with cannabis used in the previous month (76.9% versus 44.4%; P = .001) (no psychotic symptoms group); also, a greater use of benzodiazepines was observed: 75.6% versus 63.6% ( P = .046). Lower use of methadone in the group with psychosis was observed: 75.6% versus 97.3% ( P = .001). Motor alterations were tremor 58%, stereotyped movements 24%, and behaviour alteration 6%, significantly more frequent in the psychotic group. Conclusions: Thus, there was a high frequency of psychotic symptoms after intravenous cocaine use; patients with psychotic symptoms reported higher use of cannabis and benzodiazepines in the previous month and lower use of methadone. More tremors and stereotyped movements were observed in the group with psychotic symptoms. It is necessary to give a special approach to cocaine intravenous users.

Published: April 2013

Abstract
Summary: This application note describes a new scalable semi-automatic approach, the Dual Point Decision Process, for segmentation of 3D structures contained in 3D microscopy. The segmentation problem is distributed to many individual workers such that each receives only simple questions regarding whether two points in an image are placed on the same object. A large pool of micro-labor workers available through Amazon’s Mechanical Turk system provides the labor in a scalable manner.

The red blazar PMN J2345−1555 becomes blue
Authors: Ghisellini G. , Tavecchio F. , Foschini L. , Bonnoli G. , Tagliaferri G. 
Published: April 2013

Abstract
The flat spectrum radio quasar PMN J2345−1555 is a bright γ-ray source, that recently underwent a flaring episode in the infrared (IR), ultraviolet (UV) and γ-ray bands. The flux changed quasi-simultaneously at different frequencies, suggesting that it was produced by a single population of emitting particles, hence by a single and well-localized region of the jet. While the overall spectral energy distribution (SED) before the flare was typical of powerful blazars (namely two broad humps peaking in the far-IR and below 100 MeV bands, respectively), during the flare the peaks moved to the optical–UV and to energies larger than 1 GeV, to resemble low power BL Lac objects, even if the observed bolometric luminosity increased by more than one order of magnitude. We interpret this behaviour as due to a change of the location of the emission region in the jet, from within the broad-line region, to just outside. The corresponding decrease of the radiation energy density as seen in the comoving frame of the jet allowed the relativistic electrons to be accelerated to higher energies, and thus produce a ‘bluer’ SED.
