Abstract
182 single-lined hot subdwarf stars are identified by using spectra from the sixth and seventh data releases (DR6 and DR7) of the Large Sky Area Multi-Object Fibre Spectroscopic Telescope survey. We classified all the hot subdwarf stars using a canonical classification scheme, and got 89 sdB, 37 sdOB, 26 sdO, 24 He-sdOB, 3 He-sdO, and 3 He-sdB stars, respectively. Among these stars, 108 hot subdwarfs are newly discovered, while 74 stars were reported by previous catalogs. The atmospheric parameters of these stars were obtained by fitting the hydrogen (H) and helium (He) lines with non-local thermodynamic equilibrium model atmospheres. The atmospheric parameters confirm the two He sequences and the two subgroups of He-sdOB stars in our samples, which were found by previous studies in the T
eff–

diagram. Our results demonstrate different origins of field hot subdwarf stars and extreme horizontal branch stars in globular clusters, and provide strict observational limits on the formation and evolution models of the different sub-types of these evolved objects. Based on the results, we evaluated the completeness of the Geier et al. catalog. We found the fraction of hot subwarf stars is between 10% and 60%, depending on the brightness of the sample. A more accurate estimation for the hot subdwarf fraction can be obtained when similar results from composite spectra will become available.
Les alternatives aux abattoirs industriels

Published: January 2020

Les critiques radicales actuellement portées par les théoriciens et par les militants de la « libération animale » à nos relations domestiques avec les animaux visent tout particulièrement l’élevage. Celui-ci serait par essence criminel puisqu’il conduirait nécessairement à l’appropriation, à l’exploitation et à l’abattage des animaux. Or, l’élevage n’a pas le monopole de la mort des animaux domestiques.

Published: January 2020

Introduction : La barrière linguistique a des effets négatifs sur l’accès et sur la qualité des soins des patients allophones. Devant cette problématique, des dispositifs d’interprétariat professionnel physique et téléphonique en médecine libérale ont été mis en place en 2017 dans la région Pays de la Loire en s’inspirant des projets menés depuis 2010 par l’association Migration Santé Alsace. L’objectif principal de cette étude était d’évaluer la satisfaction des médecins libéraux à l’utilisation de ces dispositifs d’interprétariat en consultation avec leurs patients allophones. Méthode : Cette étude descriptive quantitative, observationnelle et prospective a été menée dans l’ensemble de la région Pays de la Loire de juin 2017 à décembre 2018. La satisfaction a été évaluée à l’aide d’un questionnaire informatique rempli par les médecins utilisateurs à la fin de chaque consultation avec interprète. Résultats : Les résultats montrent une très bonne satisfaction globale des médecins à l’utilisation de l’interprétariat professionnel, qu’il soit physique ou téléphonique. L’étude a également permis de mettre en lumière le renforcement de la relation médecin-patient et de l’alliance thérapeutique. Les principaux freins rapportés étaient les contraintes liées au temps, avec notamment un allongement de la durée de la consultation. Discussion : Cette étude souligne l’intérêt majeur du développement et de la pérennisation des dispositifs d’interprétariat en médecine libérale. L’interprétariat professionnel apparaît comme un outil facile d’utilisation ; peu de freins ont été rapportés par les utilisateurs. Il garantit le respect de la personne et de son droit à s’exprimer et à donner son consentement libre et éclairé.
The Chord Index, its Definitions, Applications, and Generalizations
Authors: Cheng Zhiyun 
Published: January 2020

AbstractIn this paper, we study the chord index of virtual knots, which can be thought of as an extension of the chord parity. We show how to use the chord index to enhance the quandle coloring invariants. The notion of indexed quandle is introduced, which generalizes the quandle idea. Some applications of this new invariant is discussed. We also study how to define a generalized chord index via a fixed finite biquandle. Finally, the chord index and its applications in twisted knot theory are discussed.
Primitive Points in Rational Polygons

Published: January 2020

AbstractLet ${\mathcal{A}}$ be a star-shaped polygon in the plane, with rational vertices, containing the origin. The number of primitive lattice points in the dilate $t{\mathcal{A}}$ is asymptotically $\frac{6}{\unicode[STIX]{x1D70B}^{2}}\text{Area}(t{\mathcal{A}})$ as $t\rightarrow \infty$. We show that the error term is both $\unicode[STIX]{x1D6FA}_{\pm }(t\sqrt{\log \log t})$ and $O(t(\log t)^{2/3}(\log \log t)^{4/3})$. Both bounds extend (to the above class of polygons) known results for the isosceles right triangle, which appear in the literature as bounds for the error term in the summatory function for Euler’s $\unicode[STIX]{x1D719}(n)$.

Abstract. Topic 3 of the Model Inter-Comparison Study for Asia (MICS-Asia) Phase III
examines how online coupled air quality models perform in simulating
wintertime haze events in the North China Plain region and evaluates the
importance of aerosol radiative feedbacks. This paper discusses the
estimates of aerosol radiative forcing, aerosol feedbacks, and possible
causes for the differences among the participating models. Over the
Beijing–Tianjin–Hebei (BTH) region, the ensemble mean of estimated aerosol
direct radiative forcing (ADRF) at the top of atmosphere, inside the
atmosphere, and at the surface are −1.1, 7.7, and −8.8 W m−2 during
January 2010, respectively. Subdivisions of direct and indirect aerosol
radiative forcing confirm the dominant role of direct forcing. During severe
haze days (17–19 January 2010), the averaged reduction in near-surface
temperature for the BTH region can reach 0.3–1.6 ∘C. The
responses of wind speeds at 10 m (WS10) inferred from different models show
consistent declines in eastern China. For the BTH region, aerosol–radiation
feedback-induced daytime changes in PM2.5 concentrations during
severe haze days range from 6.0 to 12.9 µg m−3 (<6 %).
Sensitivity simulations indicate the important effect of aerosol mixing
states on the estimates of ADRF and aerosol feedbacks. Besides, black carbon (BC) exhibits
a large contribution to atmospheric heating and feedbacks although it accounts
for a small share of mass concentration of PM2.5.

Abstract. Glacial isostatic adjustment (GIA) is a major source of uncertainty for ice and ocean mass balance estimates derived from satellite gravimetry. In Antarctica the gravimetric effect of cryospheric mass change and GIA are of the same order of magnitude. Inverse estimates from geodetic observations hold some promise for mass signal separation. Here, we investigate the combination of satellite gravimetry and altimetry and demonstrate that the choice of input data sets and processing methods will influence the resultant GIA inverse estimate. This includes the combination that spans the full GRACE record (April 2002–August 2016). Additionally, we show the variations that arise from combining the actual time series of the differing data sets. Using the inferred trends, we assess the spread of GIA solutions owing to (1) the choice of different degree-1 and C20 products, (2) viable candidate surface-elevation-change products derived from different altimetry missions corresponding to different time intervals, and (3) the uncertainties associated with firn process models. Decomposing the total-mass signal into the ice mass and the GIA components is strongly dependent on properly correcting for an apparent bias in regions of small signal. Here our ab initio solutions force the mean GIA and GRACE trend over the low precipitation zone of East Antarctica to be zero. Without applying this bias correction, the overall spread of total-mass change and GIA-related mass change using differing degree-1 and C20 products is 68 and 72 Gt a−1, respectively, for the same time period (March 2003–October 2009). The bias correction method collapses this spread to 6 and 5 Gt a−1, respectively. We characterize the firn process model uncertainty empirically by analysing differences between two alternative surface mass balance products. The differences propagate to a 10 Gt a−1 spread in debiased GIA-related mass change estimates. The choice of the altimetry product poses the largest uncertainty on debiased mass change estimates. The spread of debiased GIA-related mass change amounts to 15 Gt a−1 for the period from March 2003 to October 2009. We found a spread of 49 Gt a−1 comparing results for the periods April 2002–August 2016 and July 2010–August 2016. Our findings point out limitations associated with data quality, data processing, and correction for apparent biases.
Merging the E-journaling and the Workshop Methods to Reduce Prep-Year Students’ Writing Apprehension: An Experimental Study
Authors: Mohammed Osama , Othman Waleed , Kazeem Kayode Bakare 
Published: January 2020

Preparatory (prep) year students presently encounter a significant disparity between prior to college English writing and the much superior level of competence needed for potential academic programs in Saudi Arabia. Study has verified the operational efficacy of the methods of e-journaling and writing workshop on alleviating writing apprehension but on a separate basis. This study represents an original contribution to knowledge through exploring the effects of merging these two outstanding methods. Accordingly, the degree to which this new method reduced Saudi prep-year students' writing apprehension was statistically examined. Tools included an instructional program and a writing apprehension test. The researcher applied the randomized control-group posttest-only design in the experiment. Students were randomly assigned to an experimental group, that studied the new program and a control group, that did not experience such treatment. At the end of the experiment, the two groups were post-tested using the writing apprehension test. Statistical treatment of the results was carried out, and the findings revealed that there is a statistically substantial difference between mean scores in favor of the experimental group students. This indicates that the integration of the e-journaling and the writing workshop methods has substantial effects on minimizing students’ writing apprehension as compared to the control group students. Further research is needed to develop new consistent methods of teaching writing that cope with and benefit from the current digital outbreak, especially in the Saudi, Arab and EFL foundation/prep-year contexts.
Why Are Larger Motor Carriers More Compliant with Safety Regulations?
Authors: Miller Jason 
Published: January 2020

AbstractA common finding from both the regulatory compliance and motor-carrier safety literatures is that larger firms are more compliant with safety rules than smaller firms. However, complementary yet alternative explanations have been advanced to explain this empirical regularity. Some scholars argue larger firms' greater resource endowments allow them to make more investments to ensure safety compliance. Other scholars argue larger firms have more incentive to operate in compliance with safety rules because they have more brand equity at stake and are more exposed to regulatory enforcement. As these explanations suggest different policy implications, identifying findings uniquely consistent with one or both mechanisms is important to further efforts to improve carriers' safety compliance. This article leverages archival motor-carrier safety data and estimates different econometric models designed to isolate effects that are uniquely consistent with these alternative mechanisms. The results provide evidence uniquely consistent with each mechanism. This article concludes by explaining theoretical contributions, detailing managerial implications, and offering policy suggestions.
Measuring Sustainability Performance: A Green Supply Chain Index
Authors: Datta Pratim , Diffee Erica Nicholl 
Published: January 2020

Abstract
In an age of climatic shifts and environmental degradation, globalization and expanding supply chains are rapidly changing operational and market dynamics. Yet, how are green supply chains dimensioned as a combination of activities and practices? What phases of the supply chain can be most easily improved by adopting a green philosophy? If a company has not yet adopted a green philosophy, what stages of its supply chain can be most likely improved? This article proposes an industry framework to index and benchmark green “environmentally sustainable” supply chains. We use 21 managers and senior executives across 12 firms to derive and validate the index variables and parameters. Data from our observations and interviews allow us to derive the Green Supply Chain Index (GSCI). The comprehensive GSCI creates a baseline on which companies can measure their green supply chain performance. This article serves as a starting point for benchmarking organizational GSC initiatives and their downstream effects on organizational performance addressing requisite incentives and penalties. The index can serve as rudimentary templates for research and practices as we seek to decipher various operational and performance aspects that distinguish between green-washing and greening while offering greater scrutiny into a rapidly changing and environmentally-conscious world.
Service Learning Programs with Juvenile Offenders
Authors: Dickerson Mark , Fall Randy , Helm-Stevens Roxanne 
Published: January 2020

While prior research on service-learning has established the benefits for participating college and university students, more recent research has attempted to explore the value of service-learning projects for the recipients of the service-learning projects, typically public-school students. This study endeavors to extend this research to a special subset of this population by examining the outcome of a 6-week service-learning project in an alternative educational setting for juvenile offenders.
This service-learning project involved teams of four to five university business school students presenting a life skills curriculum to two classrooms of students who have been adjudicated through the juvenile courts. We administered an optional questionnaire to all participating students as a pretest and posttest, asking about their knowledge and skills in career readiness. We found statistically significant increases in ratings from pretest to posttest. Analyzed individually, all 28 items showed statistically significant improvements from pretest to posttest. Scales created from the items were also statistically significant, with the greatest change in items measuring Goals. We interpret these findings as an indication that adjudicated youth have a substantial need and interest in career information and training.
De toekomst is aan de surfende criminoloog

The criminologist of the future is a surfing criminologist
If, as criminologists, we really want to contribute to solutions for the great challenges of our time, we should be…surfing more. In a dynamic environment full of contradictions, we should be constantly in motion, moving left and right between different theoretical-normative perspectives as well as between methodological perspectives. This paper clarifies that surfing movement with some illustrations. It then proposes three goals for a criminological research agenda that should help us address the great challenges: actual (as opposed to superficial) relevance for practice, causal ambitions and multidisciplinarity. The paper concludes with some reflections about the organization and funding of criminological research.
Criminaliteit, digitalisering en de online sociale wereld: dezelfde processen in een nieuwe sociale context?
Authors: Weerman Frank 
Published: January 2020

Crime, digitalisation and the online social world
This contribution reflects on the criminological meaning of the still ongoing trend of digitalisation. What does this mean for crime as a phenomenon and for the explanation of criminal behaviour? Not only did we see the emergence of new types of offending, also the context of crime has changed. In principle, the underlying explanatory processes can remain the same, but their application in the online world is complex and deserves further attention. Online social interactions are not only important for online crime, but also for traditional offenses. However, systematic research on how this actually takes place is scarce.

Abstract: Suicide behavior in Colombia: A systematic review. The objective of the review was to synthesize the findings about suicide in Colombia between 2004 and 2018. Eighty-eight studies were included in the review. It is noted that most studies focus on risk factors such as depression, psychoactive substance use and family dysfunction; and only few are interested in protective factors, among which family functionality and high self-esteem are prominent; moreover, the statistical models used are mostly descriptive and studies are not based on theoretical models on suicide. Finally, some lines of research are proposed, such as deepening the theoretical models and statistical analyses used, realizing longitudinal studies and proposing intervention strategies that guide future scientific exercises in the area. Keywords: Suicide; suicidal ideation; suicidal intention; Colombia; systematic review. Resumen: El objetivo de la revisión fue sintetizar los hallazgos acerca del suicidio en Colombia entre los años 2004 a 2018. Se incluyeron 88 trabajos en esta revisión. Se destaca que la mayoría de estudios se centran en factores de riesgo como depresión, consumo de sustancias psicoactivas y disfunción familiar; y solo algunos se interesan en factores protectores, entre los que se destacan la funcionalidad familiar y la alta autoestima; además, se encontró que los modelos estadísticos empleados son en su mayoría de tipo descriptivo y los estudios no están basados en modelos teóricos sobre el suicidio.

Abstract: Instability on the dark side? Factorial structure, measurement invariance and reliability of the Dirty Dozen Dark Triad in the general population of Lima. The dark triad of the personality is a complex measure composed of three traits such as Machiavellianism, psychopathy and narcissism that are associated with destructive behaviors to the interests of others. The Dirty Dozen Dark Triad (DDDT) scale was used to evaluate the dark triad. The present study seeks to analyze the internal structure, measurement invariance and reliability of DDDT scores. 320 people were recruited (64.1% women), the average age was 24.4 and 89.7% were single. Four measurement models were identified by means of confirmatory factor analysis; the measurement invariance was also evaluated, which did not show a significant deterioration for the group according to gender. In addition, congeneric and tau-equivalent models were implemented and the accuracy of the scores for all the factors was > .70. This DDDT version provides useful evidence at the psychometric level to be implemented with a screening instrument in the psychological evaluation.Keywords: Dirty Dozen Dark Triad; validation; measurement invariance; personality.Resumen: Las triada oscura de la personalidad es una medida compleja compuesta de tres rasgos como maquiavelismo, psicopatía y narcisismo que están asociados a comportamientos destructivos a los intereses de los demás.
