AbstractSolid waste presents the potential for contamination of the soil when it is improperly managed. One of the great challenges of today's society is to promote the proper disposal of municipal solid waste in order to guarantee the safety of public health and to avoid risks to the environment. In this context, the objective of this study is to analyze the concentration profiles of heavy metals and aromatic hydrocarbons of risk that human health in landfill soil. Such works provides an important tool to evaluate the possible presence of contaminants from inappropriate waste disposal, as well as to assist in the management of waste and to prevent environmental contamination. In order to analyze cadmium (Cd), lead (Pb), nickel (Ni), arsenic (As), and mercury (Hg), which are toxic elements, and aromatic hydrocarbons, including benzene, toluene, ethylbenzene, o‐xylene, m‐xylene, and p‐xylene, soil samples were collected at different sites and depths. Neither Cd nor As was detected in any of the samples that were analyzed. Pb levels ranged from 5.34 milligrams per kilograms (mg/kg) to 7.40 mg/kg, Ni levels ranged from 2.17 mg/kg to 3.00 mg/kg, and Hg levels ranged from 75.4 micrograms per kilograms (μg/kg) to 88.3 μg/kg. The aromatic hydrocarbon compounds of benzene, toluene, ethylbenzene, and o‐xylene were below 5.5 μg/kg, and m‐, p‐xylene was below 11 μg/kg. The analysis of heavy metals and aromatic hydrocarbons present in the landfill soil showed concentrations below the soil quality guideline values of the Brazilian National Environment Council (CONAMA) Resolution 420, which has criteria for the presence of chemical substances in soil for Brazil. Therefore, the low levels of chemicals may be related to the operational time of the landfill or to the population profile of the municipality, which is predominantly composed of persons involved in family‐based agriculture.
Impact of decision to delivery time of fetal mortality in canine caesarean section in a referral population
Authors: Proctor‐Brown Lauren A. , Cheong Soon Hon , Diel de Amorim Mariana 
Published: March 2019

AbstractIn human medicine, there is a recommended decision to delivery interval (DDI), which allows for the optimization of protocols and systematic review of hospital success. In veterinary medicine, no such guideline has been established or investigated. The purpose of this study was to investigate the relationship between the interval from the decision to perform a caesarean section and the delivery of the neonates and fetal mortality at the time of surgery. One hundred and fifty canine caesarean sections were evaluated retrospectively. Caesarean cases were dichotomized to those that had at least one perinatal death and cases where all puppies survived. Factors that increased the likelihood of at least one perinatal death at caesarean section were: cases that presented as an emergency caesarean section, the dam presenting with a fetus in the vaginal canal, the dam not having a history of previous caesareans sections, and being multiparous. Even though there was no association of DDI with likelihood of having perinatal death, timing related factors that increased the likelihood of having at least one perinatal death at caesarean section were: cases where total anaesthesia time was longer than 2 h; time from induction to start of surgery was longer than 45 min and surgical time longer than 75 min. In conclusion, time is a factor in the success of canine caesarean sections and further research is needed to better define the optimal decision to delivery time in canine caesarean sections in order to optimize fetal survival and hospital protocol success rates.

Published: March 2019

AbstractAnaerobic digestion (AD) is an established method for sustainable energy production. Anaerobic digestion model No.1 (ADM1) was used to simulate methane production (MP) and volatile fatty acid (VFA) concentrations at different ammonium concentrations. In accordance with the incomplete description of several biochemical reactions and the omission of several reaction processes, ADM1 was modified with the consideration of acetic acid inhibition and valeric acid existence. ADM1_ac (ADM1 added acetic acid inhibition) could obtain better simulation accuracy of MP (goodness‐of‐fit value = 0.945), and VFA concentrations (goodness‐of‐fit values > 0.39) were all higher than ADM1_original, but cannot explain the valeric acid production. ADM1_va (ADM1 added valeric acid existence) could achieve better simulation of valeric acid (achieving a breakthrough of zero), nevertheless the accuracy of propionic and butyric acids was poorer than ADM1_ac with differences between experimental and simulation values were 5%–10% lower. With both factors coordinated, MP and VFA concentrations could be simulated accurately by ADM1_ac_va (ADM1 added acetic acid inhibition and valeric acid existence), with the highest goodness‐of‐fit values (>0.85). The results of a verification experiment with ADM1_ac_va simulation further indicated that acetic acid inhibition and valeric acid as new component were both important in ADM1.Practitioner points

ADM1_ac could simulate MP and acetate, propionate and butyrate concentrations better.

ADM1_va could explain the valerate production during AD of glucose.

ADM1_ac_va could simulate AD process quite accurately, with the highest goodness‐of‐fit values (>0.85).

Acetate inhibition and valerate existence were both important and should be considered in ADM1.
The Impact of the Homicide Decline on Life Expectancy of African American Males
Authors: Sharkey Patrick , Friedson Michael 
Published: March 2019

Abstract
Homicide is a leading cause of death for young people in the United States aged 15–34, but it has a disproportionate impact on one subset of the population: African American males. The national decline in homicide mortality that occurred from 1991 to 2014 thus provides an opportunity to generate evidence on a unique question—How do population health and health inequality change when the prevalence of one of the leading causes of death is cut in half? In this article, we estimate the impact of the decline in homicide mortality on life expectancy at birth as well as years of potential life lost for African American and white males and females, respectively. Estimates are generated using national mortality data by age, gender, race, and education level. Counterfactual estimates are constructed under the assumption of no change in mortality due to homicide from 1991 (the year when the national homicide rate reached its latest peak) to 2014 (the year when the homicide rate reached its trough). We estimate that the decline in homicides led to a 0.80-year increase in life expectancy at birth for African American males, and reduced years of potential life lost by 1,156 years for every 100,000 African American males. Results suggest that the drop in homicide represents a public health breakthrough for African American males, accounting for 17 % of the reduction in the life expectancy gap between white and African American males.
Invisible inequality leads to punishing the poor and rewarding the rich

AbstractFour experiments examine how lack of awareness of inequality affect behaviour towards the rich and poor. In Experiment 1, participants who became aware that wealthy individuals donated a smaller percentage of their income switched from rewarding the wealthy to rewarding the poor. In Experiments 2 and 3, participants who played a public goods game – and were assigned incomes reflective of the US income distribution either at random or on merit – punished the poor (for small absolute contributions) and rewarded the rich (for large absolute contributions) when incomes were unknown; when incomes were revealed, participants punished the rich (for their low percentage of income contributed) and rewarded the poor (for their high percentage of income contributed). In Experiment 4, participants provided with public education contributions for five New York school districts levied additional taxes on mostly poorer school districts when incomes were unknown, but targeted wealthier districts when incomes were revealed. These results shed light on how income transparency shapes preferences for equity and redistribution. We discuss implications for policy-makers.
“Lost Generation” in South Sudan: A Broader Approach Toward Peace Urgently Needed
Authors: Wild Hannah , Fallavier Pierre , Patel Ronak 
Published: March 2019

ABSTRACTWhat began in 2013 as the eruption of a political struggle between forces loyal to President Salva Kiir, a member of the Dinka ethnic group, and then–vice president Riek Machar, a Nuer, has splintered into a multifaction conflict. A dizzying array of armed groups have entered the fray, many unmotivated by political leverage that conventionally brings parties to a conflict to the negotiating table. Two years and tens of thousands of deaths after the 2015 signing of the Agreement on the Resolution of the Conflict in South Sudan, with no substantive progress toward meetings its terms, it is unrealistic to think that Intergovernmental Authority on Development’s recently announced High-Level Revitalization Forum will be sufficient to address the drivers of this conflict. Current policy proposals are poorly designed to address escalating intercommunal conflict and cattle raiding, both devastating forms of violence. As measures at the international level continue to be pursued, the conflict resolution strategy should also include a more comprehensive approach incorporating local actors in order to build momentum toward long-term stability. In this article, we highlight gaps in the current dialogue around a political solution in South Sudan, as well as domains that must be part of the next push for peace.

Transmission pathways of multidrug-resistant organisms in the hospital setting: a scoping review
Authors: Blanco Natalia , O’Hara Lyndsay M. , Harris Anthony D. 
Published: March 2019

AbstractBackground:Prevalence of multidrug-resistant microorganisms (MDROs) continues to increase, while infection control gaps in healthcare settings facilitate their transmission between patients. In this setting, 5 distinct yet interlinked pathways are responsible for transmission. The complete transmission process is still not well understood. Designing and conducting a single research study capable of investigating all 5 complex and multifaceted pathways of hospital transmission would be costly and logistically burdensome. Therefore, this scoping review aims to synthesize the highest-quality published literature describing each of the 5 individual potential transmission pathways of MDROs in the healthcare setting and their overall contribution to patient-to-patient transmission.Methods:In 3 databases, we performed 2 separate systematic searches for original research published during the last decade. The first search focused on MDRO transmission via the HCW or the environment to identify publications studying 5 specific transmission pathways: (1) patient to HCW, (2) patient to environment, (3) HCW to patient, (4) environment to patient, and (5) environment to HCW. The second search focused on overall patient-to-patient transmission regardless of the transmission pathway. Both searches were limited to transmission of methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus, multidrug-resistant A. baumannii, and carbapenem-resistant Enterobacteriaceae. After abstract screening of 5,026 manuscripts, researchers independently reviewed and rated the remaining papers using objective predefined criteria to identify the highest quality and most influential manuscripts.Results:High-quality manuscripts were identified for all 5 routes of transmission. Findings from these studies were consistent for all pathways; however, results describing the routes from the environment/HCW to a noncolonized patient were more limited and variable. Additionally, most research focused on MRSA, instead of other MDROs. The second search yielded 10 manuscripts (8 cohort studies) that demonstrated the overall contribution of patient-to-patient transmission in hospitals regardless of the transmission route. For MRSA, the reported cross-transmission was as high as 40%.Conclusions:This scoping review brings together evidence supporting all 5 possible transmission pathways and illustrates the complex nature of patient-to-patient transmission of MDROs in hospitals. Our findings also confirm that transmission of MDROs in hospitals occurs frequently, suggesting that ongoing efforts are necessary to strengthen infection prevention and control to prevent the spread of MDROs.
Perceived organizational support, psychological entitlement, and extra-role behavior: The mediating role of knowledge hiding behavior

Published: March 2019

AbstractResearch on the knowledge sharing has exploded over the past decades due to trends and integration of knowledge and talent management in modern workplace. However, knowledge hiding has been left unexplored; moreover, efforts to foster knowledge sharing remain because employees are unwilling to share their knowledge for several reasons. Drawing on psychological ownership and social exchange theory, this article investigated the nexus between perceived organizational support, psychological entitlement, knowledge hiding behavior, and extra-role behavior, and the mediating role of knowledge hiding behavior. Utilizing survey data collected from 375 employees in Jordanian commercial banks, a structural equation modeling was applied to analyze the data. Results from structural equation modeling show that (1) perceived organizational support has a positive impact on extra-role behavior, (2) knowledge hiding behavior has a negative impact on extra-role behavior, (3) psychological entitlement has a positive impact on knowledge hiding behavior, and (4) knowledge hiding behavior mediated the relationship between psychological entitlement and extra-role behavior. Implications for theory and practice are discussed.
Projected effects of temperature changes on the Italian Western Tauri glaciers (Eastern Alps)

Published: March 2019

ABSTRACTA linear model was used to investigate the behaviour of the Italian Western Tauri glaciers as a result of temperature changes projected for the 21st century. The model estimates the temperature variations once the glacier snout length variations are known and vice versa: it estimates the glacier snout length variations once the air temperature variations are known or predicted. The 46 glaciers of the Italian Western Tauri, 35 (76%) of which have areas smaller than 0.5 km2 and only 7 (15%) larger than 1 km2, are mostly mountain type glaciers and only three are presently valley glaciers. The model has been forced by the air temperature projections of the A1B emission scenario, which indicates an increase in temperature of 2.7°C from 2015 to 2100. The results show a shortening of more than 35% for mountain glaciers by 2100 with a surface loss of more than 60% and smaller reductions for valley glaciers. The consequent fragmentation into smaller units would lead to the extinction of 95% of the existing glaciers by the end of the century, possibly leaving only the valley glaciers surviving.
Misperceptions of Chinese Investments in Canada and Their Correction: Evidence from a Survey Experiment
Authors: Li Xiaojun , Kuang Yingqiu , Zhang Linting 
Published: March 2019

AbstractForeign direct investment (FDI) from China has recently met with increasing public opposition in many host nations. Why does the public respond less favourably to Chinese FDI than to FDI from other countries? We explore this question by conducting a series of survey experiments in Canada, where the majority of the public holds a negative opinion of Chinese investment. We find that the bias can be attributed to innumeracy about the relative size of China's FDI and misinformation about investment rules that govern FDI projects in Canada. Correcting both misperceptions substantially reduces the bias of respondents against FDI projects from China. These results suggest that corrective information can lead to positive change in public attitudes, a finding that has important policy implications for Canadian leaders hoping to expand the country's business ties with China.
Who are the Asset-Poor in China: A Comprehensive Description and Policy Implications

Published: March 2019

AbstractThere is a large body of literature asserting that household asset holdings play a critical role in prospects of economic and social well-being. This study examines asset-poverty rates in China using the 2013 survey data from the Chinese Household Income Project (CHIP). The results indicate that asset-poverty rates in urban China were lower than those of developed countries, whereas rural and migrant households experienced more serious asset poverty than their counterparts in urban China. In addition, the asset-poverty rates were at least twice the income-poverty rates in China according to the different poverty lines used in the study. Several demographic characteristics were found associated with asset poverty. To assist the Chinese government in reaching its goal of eradicating absolute poverty by 2020 through targeted poverty alleviation, this study suggests including assets in the description and alleviation of poverty.
Functional disorders can also be explained through a non-reductionist application of network theory
Authors: Hyland Michael E. 
Published: March 2019

AbstractA network structure explains why reductionism is not possible for mental illness, but the same argument applies for the somatic symptoms of functional disorders. Because the covariation of symptoms of functional disorders cannot be explained in terms of symptom-to-symptom causality, explanation requires a network of biological mechanisms having emergent properties that cannot be reduced to biology.
Network models can help focus research on the role of culture and context in psychopathology, but don't discount latent variable models
Authors: Jayawickreme Nuwan , Rasmussen Andrew , Karasz Alison , Verkuilen Jay , Jayawickreme Eranda 
Published: March 2019

AbstractBorsboom et al. correctly note that the use of latent variable models in cross-cultural research has resulted in a futile search for universal, biological causes of psychopathology; however, this is not an inevitable outcome of such models. While network analytic approaches require further development, network models have the potential to better elucidate the role of cultural and contextual variables related to psychopathology.
Beyond trait reductionism: Implications of network structures for dimensional models of psychopathology
Authors: Bornstein Robert F. 
Published: March 2019

AbstractBorsboom et al. discuss the implications of network structures for neurobiology-based reductionism, but inherent in the network approach is that dimensional models of psychopathology are untenable as well. Insofar as mental disorders are complex dynamic constellations of symptoms, the “trait reductionism” of dimensional psychopathology frameworks suffers from the same limitations as neurobiological reductionism.
Reductionism in retreat
Authors: Borsboom Denny , Cramer Angélique O. J. , Kalis Annemarie 
Published: March 2019

AbstractWe address the commentaries on our target article in terms of four major themes. First, we note that virtually all commentators agree that mental disorders are not brain disorders in the common interpretation of these terms, and establish the consensus that explanatory reductionism is not a viable thesis. Second, we address criticisms to the effect that our article was misdirected or aimed at a straw man; we argue that this is unlikely, given the widespread communication of reductionist slogans in psychopathology research and society. Third, we tackle the question of whether intentionality, extended systems, and multiple realizability are as problematic as claimed in the target article, and we present a number of nuances and extensions with respect to our article. Fourth, we discuss the question of how the network approach should incorporate biological factors, given that wholesale reductionism is an unlikely option.
Seven-year itch: the UK Government’s difficult relationship with the food and drink industry since Healthy Lives, Healthy People: A Call to Action on Obesity in England (2011)
Authors: Flint Stuart W , Oliver Emily J 
Published: March 2019

AbstractObjectiveUnhealthy food and drink consumption is associated with a range of physical and mental health concerns. In response, public health policies have been developed targeting a reduction in obesity in particular. In the present commentary we argue that government–industry partnerships have reduced the effectiveness of resultant policies and explore why.DesignPerspectives of authors.SettingUK.ParticipantsPopulations in the UK; UK Government.ResultsIndustry involvement has presented three interrelated challenges for the UK Government: (i) balancing collaboration while maintaining appropriate distance from industry stakeholders; (ii) resultant production of ‘watertight’ and effective legislation or intervention; and (iii) actual or perceived limited sanctioning or bargaining power.ConclusionsIndustry involvement in public health policy making has led to weak action. Support with policy implementation (rather than development) and genuine ‘buy-in’ from industry could accelerate the pace of public health improvement.
Mental health during the Syrian crisis: How Syrians are dealing with the psychological effects
Authors: Hedar Mazen 
Published: March 2019

AbstractLooking at the physical damage caused by the Syrian war, one can begin to imagine the scale of the psychological toll that eight years of crisis have taken on the Syrian people. In a country where mental health was still considered an emerging field before the war, Syrians are working to address and manage the mental health and psychological effects of war. Despite this disastrous situation, there appears to have been significant progress in the field of mental health during the crisis. This article explores the mental health situation in Syria prior to 2011, the effects of the crisis on Syrians, and how these have been managed in recent years. It concludes by citing some examples of progress that have been made in mental health care in Syria and discussing some of the challenges that remain to be addressed.
