The career prospects of overeducated Americans
Authors: Clark Brian , Joubert Clément , Maurel Arnaud 
Published: March 2017

Abstract
In this paper we analyze career dynamics for US workers who have more schooling than their peers in the same occupation. We use data from the NLSY79 combined with the CPS to analyze transitions into and out of overeducated employment, together with the corresponding effects on wages. Overeducation is a fairly persistent phenomenon at the aggregate and individual levels, with 66% of workers remaining overeducated after 1 year. Overeducation is not just more common but also more persistent among blacks and low-AFQT individuals. Further, the hazard rate out of overeducation drops by about 60% during the first 5 years spent overeducated. However, the estimation of a mixed proportional hazard model suggests that this is attributable to selection on unobservables rather than true duration dependence. Lastly, overeducation is associated with lower current as well as future wages, consistent with scarring effects.

Published: March 2017

Background. Urolithiasis is a disease with high recurrence rate, 30-50% within 5 years. The aim of the present study was to learn the effects of citrus-based products on the urine profile in healthy persons and people with urolithiasis compared to control diet and potassium citrate. Methods. A systematic review was performed, which included interventional, prospective observational and retrospective studies, comparing citrus-based therapy with standard diet therapy, mineral water, or potassium citrate. A literature search was conducted using PUBMED, COCHRANE, and Google Scholar with “citrus or lemonade or orange or grapefruit or lime or juice” and “urolithiasis” as search terms. For statistical analysis, a fixed-effects model was conducted when p > 0.05, and random-effects model was conducted when p < 0.05. Results. In total, 135 citations were found through database searching with 10 studies found to be consistent with our selection criteria. However, only 8 studies were included in quantitative analysis, due to data availability. The present study showed a higher increased in urine pH for citrus-based products (mean difference, 0.16; 95% CI 0.01-0.32) and urinary citrate (mean difference, 124.49; 95% CI 80.24-168.74) compared with a control group. However, no differences were found in urine volume, urinary calcium, urinary oxalate, and urinary uric acid. From subgroup analysis, we found that citrus-based products consistently increased urinary citrate level higher than controls in both healthy and urolithiasis populations. Furthermore, there was lower urinary calcium level among people with urolithiasis. Conclusions. Citrus-based products could increase urinary citrate level significantly higher than control. These results should encourage further research to explore citrus-based products as a urolithiasis treatment.
Is Reshoring Better Than Offshoring? The Effect of Offshore Supply Dependence
Authors: Chen Li , Hu Bin 
Published: March 2017

In this paper we investigate the effect of offshore supply dependence (OSD) on offshoring–reshoring profit comparisons. We find that OSD hampers a reshoring manufacturer’s responsiveness to demand information updates and may significantly affect offshoring–reshoring comparisons, such that reshoring may yield lower profits than offshoring in many cases, including when offshoring has no baseline-cost advantage. We then show that OSD also affects how salient costs such as customs duties and shipping costs influence offshoring–reshoring profit comparisons. We further identify common-component designs as a mitigating measure to make reshoring more appealing under OSD, and numerically confirm the robustness of our results.

Time-Dependent Hazardous-Materials Network Design Problem
Authors: Esfandeh Tolou , Batta Rajan , Kwon Changhyun 
Published: March 2017

We extend the hazardous-materials (hazmat) network design problem to account for the time-dependent road closure as a policy tool to reduce hazmat transport risk by altering carriers’ departure times and route choices. We formulate the time-dependent network design problem using an alternative-based model with each alternative representing a combined path and departure-time choice. We also present an extended model that can not only account for consecutive time-based road closure policies but also allow stopping at the intermediate nodes of the network in the routing/scheduling decisions of the carriers. Heuristic algorithms based on column generation and label setting are presented. To illustrate the advantages that can be gained through the use of our methodology, we present results from numerical experiments based on a transportation network from Buffalo, New York. To investigate the impact of the extensions, we consider three versions of the problem by gradually refining the model. We show that under consideration of extensions, the design policies are more applicable and effective. The online appendix is available at https://doi.org/10.1287/trsc.2016.0698 .
Meta-Analysis of Price Responsiveness of Timber Supply

Published: March 2017

Abstract
Modeling and projecting timber supply requires a good understanding of how supply responds to price. The price elasticity of supply (PELS) reported in the literature varies greatly, indicating that conclusions regarding price signaling in the timber market are mixed. Therefore, we conducted a meta-analysis to determine the key factors associated with the heterogeneity of PELS of primary timber product supply by examining data from numerous studies conducted around the world. Twelve “moderator” variables were examined to explore differences in PELS. Moderators with significant impacts on variation of PELS included forest products, geographic regions, econometric models, and data type. Furthermore, two-level categorical variables contained within the econometric models including standing stock were found to have significant influence on the heterogeneity of PELS. Variation in PELS also depended on whether or not the supply models accounted for price inflation, and the time period when the study was conducted. These findings may improve the understanding of the dynamics of price signaling in timber markets, and further improve the efficiency of timber supply and forecasting models for market participants and policy makers.
On stabilizers of algebraic function fields of one variable

Published: March 2017

AbstractLetK~$\tilde K$be a fixed algebraic closure of an infinite fieldK. We consider an absolutely integral curveΓinPKn$\mathbb{P}_{K}^{n}$withn≥ 2. The curveΓK~$\it\Gamma_{\tilde{K}}$should have only finitely many inflection points, finitely many double tangents, and there exists no point inPK~n$\mathbb{P}_{\tilde{K}}^{n}$through which infinitely many tangents toΓK~$\it\Gamma_{\tilde{K}}$go. In addition there exists a prime numberqsuch thatΓK~$\it\Gamma_{\tilde{K}}$has a cusp of multiplicityqand the multiplicities of all other points ofΓK~$\it\Gamma_{\tilde{K}}$are at mostq. Under these assumptions, we construct a non-empty Zariski-open subsetOofPK~n$\mathbb{P}_{\tilde{K}}^{n}$such that ifn≥ 3, the projection from each pointo∈O(K) birationally mapsΓonto an absolutely integral curveΓ′inPKn−1$\mathbb{P}_{K}^{n-1}$with the same properties asΓ(keepingqunchanged). Ifn= 2, then the projection from eacho∈O(K) mapsΓontoPK1$\mathbb{P}_{K}^{1}$and leads to astabilizingelementtof the function fieldFofΓoverK. The latter means thatF/K(t) is a finite separable extension whose Galois closureF^${\hat F}$is regular overK.

The death of a medieval Danish warrior. A case of bone trauma interpretation
Authors: Forsom Eva , Boel Lene Warner Thorup , Jaque Bo , Mollerup Lene 
Published: March 2017

Abstract
In 1934 a grave was found in the church ruins of the Cistercian Abbey at Øm in central Jutland, Denmark (founded in 1172, demolished 1561 AD). The grave contained the skeletal remains of an individual lying in a supine position with the head towards the west. The anthropological analysis revealed that the remains belonged to a young male, aged 25-30 years at death and approximately 162.7 cm tall. He had 9 perimortem sharp force lesions, five of which were cranial and four were postcranial, indicating he suffered a violent death in a swordfight.
This paper presents a detailed analysis and description of the individual lesions and their probable effect on the soft tissue, followed by a suggestion for the most likely order of the blows which caused the lesions, and finally a tentative reconstruction of the battle accompanied by photographs. This case illustrates both that forensic pathology can be very useful when applied to an archaeological case and suggests that the forensic pathologist could benefit from examination of ancient cases when interpreting bone lesions in modern cases.
Maltreatment Risk Among Children With Disabilities
Authors: Maclean Miriam J. , Sims Scott , Bower Carol , Leonard Helen , Stanley Fiona J. , O’Donnell Melissa 
Published: March 2017

BACKGROUND:
Children with disabilities are at increased risk of child maltreatment; however, there is a gap in the evidence about whether all disabilities are at equal risk and whether risk factors vary according to the type of disability.

METHODS:
A population-based record-linkage study of all children born in Western Australia between 1990 and 2010. Children with disabilities were identified by using population-based registers and risk of maltreatment determined by allegations reported to the Department for Child Protection and Family Support.

RESULTS:
Although children with disabilities make up 10.4% of the population, they represent 25.9% of children with a maltreatment allegation and 29.0% of those with a substantiated allegation; however, increased risk of maltreatment was not consistent across all disability types. Children with intellectual disability, mental/behavioral problems, and conduct disorder continued to have increased risk of an allegation and substantiated allegation after adjusting for child, family, and neighborhood risk factors. In contrast, adjusting for these factors resulted in children with autism having a lower risk, and children with Down syndrome and birth defects/cerebral palsy having the same risk as children without disability.

CONCLUSIONS:
The prevalence of disabilities in the child protection system suggests a need for awareness of the scope of issues faced by these children and the need for interagency collaboration to ensure children’s complex needs are met. Supports are needed for families with children with disabilities to assist in meeting the child’s health and developmental needs, but also to support the parents in managing the often more complex parenting environment.
O lugar nos estudos toponímicos: reflexões
Authors: Andrade Karylleila Santos 
Published: March 2017

Resumo: Este texto parte da seguinte questão norteadora: qual é a posição ou status que lugar ocupa nos estudos toponímicos? O objetivo geral é discutir lugar como categoria na disciplina toponímia para, em seguida, propor seu alargamento conceptual. Utilizar-se-á a abordagem teórica da Geografia Cultural e Humanista, a partir do viés da Fenomenologia, como também, os princípios teórico-metodológicos da disciplina Toponímia. É uma pesquisa de cunho qualitativa e interpretativista. Conclui-se, nesta etapa do trabalho, que lugar pode ser interpretado como categoria, pois trata-se da extensão/apreensão das relações (motivações) as quais são estabelecidas entre o homem e o próprio nome de lugar: é a sua gênese. O alçamento, enquanto categoria central, deu-se com uma discussão prévia das categorias espaço, território, paisagem e lugar. Daí o conceito em uma dimensão analítica: motivacional, histórica, linguística, ideológica, social, identitária. Quanto à sua extensão semântica, essa acontece no plano da abstração do vínculo que se estabelece entre o denominador e o designatum: como sentimento de pertencimento, afetividade, mundo vivido e experienciado.Palavras-chave: lugar; categoria; toponímia; geografia cultural e humanista.Abstract: This paper stems from the following guiding question: what is the position or status that place occupies in toponymic studies? The overall objective is to discuss place as a category in toponymic studies and, then, to propose an extension for its concept. We will use the theoretical approach of Cultural and Humanistic Geography, from the the point of view of Phenomenology, and also the theoretical and methodological principles of Toponymy as a discipline. It is a research of qualitative and interpretative nature. It can be concluded, at this stage of the work, that place can be interpreted as a category because it is the extension/seizure of relations (motivation) that are established between man and the place name itself: it is its genesis. Its rising, as a nuclear category, was achieved after prior discussion of space, territory, landscape and place categories. Hence the concept in an analytical dimension: motivational, historical, linguistic, ideological, social, identitary. As for its semantic extension, this happens in the abstraction plan of the bond that is established between the denominator and the designatum: as sense of belonging, affection, world lived and experienced.Keywords: place; category; toponymy; cultural and humanistic geography.
A semiótica das paixões e a análise da dimensão passional dos enunciados
Authors: Lima Eliane Soares de 
Published: March 2017

Resumo: Adotando uma perspectiva diacrônica, a intenção deste artigo é a de apresentar os desenvolvimentos teóricos e metodológicos que têm marcado o estudo das paixões dentro do quadro geral da semiótica de linha francesa. Interessa a partir daí retomar os apontamentos que assinalaram a chamada “virada fenomenológica” da teoria – enquanto momento no qual a preocupação com o sensível, com as condições de emergência do sentido, passa a ocupar o centro da atenção dos semioticistas – e discutir os desafios impostos, a necessidade de contínua evolução do modelo de análise criado para dar conta desse outro universo de significação. Assim, com base nos desdobramentos mais recentes da teoria, agora voltados à problemática da enunciação, do sentido configurado em ato, propõe-se uma reformulação do esquema passional canônico tal como concebido no livro Semiótica das paixões, de Greimas e Fontanille.Palavras-chave: semiótica; paixões; dimensão passional; modalidades; tensividade. Abstract: Adopting a diachronic perspective, the aim of this article is to present the theoretical and methodological developments that have characterized the study of passions within the general framework of French Semiotics. From this perspective, we’d like to go back to the writings which have marked the so-called “phenomenological turn” of the theory – as the moment when the concern with the sensitive, with the conditions of meaning emergence, becomes a major issue for semioticians – and discuss the challenges inflicted, the need of a constant evolution on the pattern of analysis created in order to examine this alternative universe of signification. Thus, based on the theory’s most recent developments, having to do with enunciation, with meaning set up in act, we propose a reorganization of the canonical pathemic schema as featured in Greimas and Fontanille’s Sémiotique des passions.Keywords: semiotics; passions; emotional dimension; modality; tensivity.

Published: March 2017

INTRODUCCIÓN: las infecciones pulmonares son comunes en los pacientes inmunocomprometidos. La carga viral de citomegalovirus se utiliza de rutina para determinar en qué momento se debe iniciar la terapia preventiva en hospederos inmunocomprometidos, diagnosticar enfermedad activa y supervisar la repuesta a una terapia implementada. OBJETIVO: describir el valor de la carga viral de citomegalovirus en líquido de lavado bronquioalveolar vs. sangre periférica en población pediátrica con signos de infección respiratoria. MATERIALES Y MÉTODOS: estudio descriptivo, observacional de 16 pacientes pediátricos y 19 episodios, a quienes se les realizó, de manera simultánea, la carga viral de citomegalovirus en sangre y lavado bronquioalveolar. RESULTADOS Y CONCLUSIONES: todas las cargas virales de citomegalovirus realizadas en lavado bronquioalveolar fueron positivas y en general se obtuvieron valores más elevados que en sangre, lo que sugiere una mayor sensibilidad de la prueba cuando se realiza en este tipo de muestra, en pacientes con sospecha clínica de infección respiratoria por citomegalovirus, lo cual la convierte en una ayuda diagnóstica importante según lo muestran los resultados obtenidos.

Resumo: Neste trabalho analisamos os artigos publicados entre 2005 a 2011 no GT de Didática, da ANPEd. Os objetivos são: a) captar as bases epistemológicas que fundamentam as discussões dos pesquisadores no âmbito do ensino e da aprendizagem de Ciências; e b) provocar o pensamento para as possíveis linhas de fuga de um ensino de Ciências pautado na convivência com o caos e a diferença. Metodologicamente a análise foi pautada na filosofia da diferença a partir das teorias de Deleuze e Guattari e propõe um breve exercício de desconstrução/problematização dos alicerces do pensamento moderno aplicados à educação e que aparecem nesses artigos. O resultado demonstra como as teorias que subsidiam os artigos estão atreladas ao pensamento da representação e que a Didática para/no ensino de Ciências produz um aligeiramento ao confundir ou precipitar a criação de “metodologias” de ensino a partir das proposições teórico-científicas oriundas da psicologia e da sociologia.

Published: March 2017

The using of molecular marker is an efficient approach to analyze the genetic diversity and it can be used widely in biological studies. The characterization of rice germplasms by using molecular markers is more precise because it is not influenced by environmental factors. The purpose of this study was to analyze the genetic diversity of 24 varieties of lowland and upland rice by using 15 SSR markers. The results showed as many as 86 alleles were detected in 24 rice varieties by using 15 SSR markers, with the average number of alleles per marker was 5,73 and the range of alleles per locus was 2-10. The average of major allele frequency was 43% with the lowest score was 26% on RM6997 and RM536 markers and the highest score was 65% on RM60 marker. A total of 14 SSR markers were able to discriminate heterozygous alleles within a range between 0,17 (RM105) to 1,00 (RM201, RM263, RM416, RM518 and RM223). The value of gene diversity ranged from 0,48 (RM60) to 0,81 (RM536) with an average of 0,70. The value of PIC (Polymorphic Information Content) ranged from 0,38 (RM105) to 0,78 (RM536) with an average of 0,65. The phylogenetic analysis showed that 24 rice varieties separate into two main clusters in the coefficient of 0,63. The first cluster consists of 12 lowland varieties and the second cluster consists of 12 upland varieties. The genetic diversity data in this study were expected could be a valuable information in the rice plant breeding activities in the future.
A New Approach to the Modeling of Hydraulic-Fracturing Treatments in Naturally Fractured Reservoirs
Authors: Li Sanbai , Zhang Dongxiao , Li Xiang 
Published: March 2017

Summary
A fully coupled thermal/hydromechanical (THM) model for hydraulic-fracturing treatments is developed in this study. In this model, the mixed finite-volume/finite-element method is used to solve the coupled system, in which the multipoint flux approximation L-method is used to calculate interelement fluid and heat flux. The Gu et al. (2011) crossing criterion is extended to a 3D scenario to delineate the crossing behaviors as hydraulic fractures meet inclined natural fractures. Moreover, the modified Barton et al. (1985) model proposed by Asadollahi et al. (2010) is used to estimate the fracture aperture and model the shear-dilation effect. After being (partially) verified by means of comparison with results from the literature, the developed model is used to investigate complex-fracture-network propagation in naturally fractured reservoirs. Numerical experiments show that the key factors controlling the complexity of the induced-fracture networks include stress anisotropy, injection rate, natural-fracture distribution (fracture-dip angle, strike angle, spacing, density, and length), fracture-filling properties (the degree of cementation and permeability), fracture-surface properties (cohesion and friction angle), and tensile strength of intact rock. It is found that the smaller the stress anisotropy and/or the lower the injection rate, the more complex the fracture network; a high rock tensile strength could increase the possibility of the occurrence of shear fractures; and under conditions of large permeability of fracture filling combined with small cohesive strength and friction coefficient, shear slip could become the dominant mechanism for generating complex-fracture networks. The model developed and the results presented can be used to understand the propagation of complex-fracture networks and aid in the design and optimization of hydraulic-fracturing treatments.
