Risk in New Sexual Relationships: Trajectories of Protection*
Authors: Bell David C. 
Published: October 2018

Abstract
How do sex risk and protection change over the course of a relationship? It is often claimed that protection generally declines over the course of relationships. This 3-year longitudinal study examines 412 new sexual relationships described by 126 adult participants and tests this claim. Analyses identify four relationship trajectories: only 15% of new sex relationships show a declining trajectory of protection; another 12% show only a temporary decline. Population average analyses previously interpreted to show a decline in protection are shown here to be is largely explained by the attrition of the low trust, high protection relationships that creates the association between higher trust and lower protection. The long-term relationships turn out mostly not to have been low trust, high protection relationships at the start. Instead they have mostly always been high trust, low protection relationships. Other proposed theories, notably self-protection and power theories are not supported, while drug use is supported for 15% of the sample. Only trust and secondary partners successfully account for the observed patterns of protection and attrition. Actors seem to be concerned to protect their partners, using more protection with a secondary partner who might provide a risk to the primary partner.

Published: October 2018

Abstract
Background: The Brief Child and Family Phone Interview (BCFPI) is a standardized intake and follow-up interview used in child and adolescent mental health services (CAMHS). Although it has shown good validity compared with other measures using parent reports, it has not yet been compared with diagnoses derived from a Longitudinal Expert All Data (LEAD) procedure, which includes information from separate diagnostic interviews with parent(s) and child. The aim was to compare the BCFPI evaluation in an outpatient child and adolescent psychiatry setting with an evaluation derived from a LEAD procedure.
Methods: At four Swedish outpatient CAMHS, 267 patients were interviewed at intake with the BCFPI. Within six weeks, patients and parents were interviewed separately with the 2009 version of the semi-structured Kiddie Schedule for Affective Disorders and Schizophrenia for School-age Children, Present and Lifetime Version (K-SADS-PL) and parents completed the Child Behavior Checklist (CBCL). LEAD diagnoses were subsequently determined by two senior clinicians based on 1.2 years of clinical records including the K-SADS-PL and ensuing information from further assessments, psychological tests, information from teachers and other informants as well as treatment outcome. The Diagnostic and Statistical Manual of Mental Disorders subscales from the CBCL and the subscales from the BCFPI were compared with LEAD diagnoses. These measured symptoms of attention-deficit hyperactivity disorder, oppositional defiant disorder, conduct disorder, separation anxiety disorder, generalized anxiety disorder, and major depressive disorder.
Results: The criterion validity for BCFPI versus LEAD diagnoses was fair for oppositional defiant disorder (area under curve, 0.73), generalized anxiety disorder (0.73) and major depressive disorder (0.78), good for attention-deficit hyperactivity disorder (0.81) and conduct disorder (0.83), and excellent for separation anxiety disorder (0.90). The screening properties of BCFPI and CBCL were similar.
Conclusion: The BCFPI is a concise and valid tool, performed along with the larger and more established CBCL, in screening for major psychiatric disorders. It is well suited as an intake interview in CAMHS.
Identity formation and evaluation in adolescence and emerging adulthood: How is it associated with depressive symptoms and loneliness?
Authors: Lindekilde Nanna , Lübeck Marlene , Lasgaard Mathias 
Published: October 2018

Abstract
Background: Developing a personal identity is a challenging task throughout adolescence and emerging adulthood. In 2006, Luyckx and colleagues developed an identity model differentiating identity formation into exploration and commitment dimensions. Previous studies have documented associations between the identity dimensions and different aspects of mental health.
Objective: Based on Luyckx and colleagues five-dimensional identity model, the present study investigated associations between identity dimensions and intra- and interpersonal aspects of mental health.
Method: In total, 524 high school students (65 % female; mean age = 18.27; SD = 1.15) participated in a cross-sectional study measuring five identity dimensions and intra- and interpersonal aspects of mental health (depressive symptoms and loneliness). Correlation coefficients were calculated and hierarchical regression analyses were performed.
Results: Only two of the five identity dimensions: Identification with Commitment and Ruminative Exploration, were significantly associated with depression. None of the five identity dimensions were associated with loneliness.
Conclusions: The findings suggest that the identity dimensions are not specifically associated with feelings of loneliness but that Identification with Commitment and Ruminative Exploration may be key components in the development of depressive symptoms. Future studies exploring the associations of identity dimensions and multiple intra- and interpersonal aspects of mental health are recommended.
Simulation of Water Movement in Layered Water‐Repellent Soils using HYDRUS‐1D
Authors: Wang Xiaofang , Li Yi , Si Bingcheng , Ren Xin , Chen Junying 
Published: October 2018

Core Ideas
HYDRUS‐1D performed well for the water movement in layered water repellent soils.
Two scenarios of silt loam/sand and sand/silt loam with water repellent soils, were applied.
HYDRUS‐1D simulated infiltration parameters by differing two layered water repellent scenarios.
Water repellency has many negative influences on soil water movement. However, simulations of water movement in layered water repellent (WR) soils are limited. Our objectives are to calibrate and validate the infiltration parameters and simulate water movement in layered WR soils based on ponded infiltration experiments conducted in wettable, slightly WR, strongly WR, and severely WR soils. Our experiments were conducted in 50‐cm long soil columns with two layer scenarios: Silt loam overlying (/) sand and sand/silt loam. For WR treatments, the surface soil was all 5 cm. For the wettable treatments, surface soils with thicknesses of 10‐ and 20‐cm layer sequences were added. Calibrations were conducted based on cumulative infiltration (CI), distance of the wetting front (Zf), and volumetric soil water content (θv) in the wettable and WR silt loam/sand treatments. Validations were conducted via eight additional treatments. The 12 WR layered soil treatments were selected for simulation. Three statistical parameters including the relative root mean square error (RRMSE), were used to assess the HYDRUS‐1D performance. The RRMSE for calibration and validation, ranged from 3.2 to 10% and 2.5 to 13.6%, respectively, confirming that HYDRUS‐1D was able to accurately describe water movement in layered WR soils. For the severely WR treatments, infiltration time reached 2800 h in silt loam/sand scenario and 1000 h in sand/silt loam scenario when water infiltrated to a depth of 35 cm. Overall, soil water repellency was more important than the interlayer position in regard to affecting water movement in layered soils, especially in the sand/silt loam scenario.
Surface Reactions of Phosphorus Extracted by the Modified Truog Method to Predict Soil Intrinsic Pools
Authors: Shuai Xiufu 
Published: October 2018

Core Ideas
Constant Capacitance Model was applied to soil P extraction reactions by the modified Truog test.
Sulfate in Truog extractant was adsorbed to form a negative electrostatic potential at soil particle surface.
Sulfate replaced phosphate by ligand exchange mechanism at soil particle surface.
The surface electrostatic potential reduced the reaction rates of P extraction.
Weakly and tightly adsorbed phosphorus (P) pools were proposed as a novel approach to quantify the actual amount of P adsorbed at the particle surface of tropical soils, and the extraction efficiencies (percentages) of the two pools by the modified Truog method were important for the measurements of the pools. The objectives of this study were to: (i) study the surface reactions in the method and (ii) predict the extraction efficiencies of the pools from soil properties. The first surface reaction in the method was the instant adsorption of sulfate in the extractant to form a monodentate inner‐sphere complex. The second and third surface reactions in the method were the ligand exchanges between sulfate and phosphate, and the new mechanisms proposed in this study included a step of slow formation of intermediate complexes in which both sulfate and phosphate were bound to metal cations and a subsequent step of instantly releasing phosphate from the intermediate complexes. The negative potential formed in the first reaction resulted in difficulty for sulfate to access the surface layer in the ligand‐exchange reactions. The double exponential models were derived from constant capacitance model (CCM) and kinetics of surface reactions. Results showed the models fit the experimental measurements well. The extraction efficiencies of the pools were determined by surface site density of clay. The consistency of the estimated capacitance density 2.421 F m−2 and literature indicated that CCM was valid to describe the surface reactions in the method and applicable to soil P management.
Water remediation contaminated with MTBE using a catalytic oxidation process in batch reactor: influence of the cerium loading on the activity and CO2 selectivity
Authors: Torres-Torres G. , Cuauhtémoc-López I. , Espinosa de los Monteros A. , Frías-Márquez Dora Ma. , Arévalo Pérez J. C. , del Angel G. 
Published: October 2018

Abstract
Destruction of methyl tert-butyl ether (MTBE) in liquid phase and in a batch reactor was studied using ruthenium catalysts over alumina support, modified with different cerium loadings. Ce loading increment causes an increase in the particle size from 1.26 nm to 2.3 nm, enhancing the MTBE oxidation (at 150 °C), and the selectivity toward CO2. The high catalytic activity of Ru/ACe10 is attributed to the species Ce4+-O2−-M that could favor the oxygen transfer between the catalyst surface and the adsorbed species by a redox mechanism. Thus, CeOx plays an important role in both enhancing the affinity between MTBE and catalyst during MTBE adsorption and promoting the catalytic activity for MTBE oxidation.

Los guerrilleros en la narrativa de Juan José Saer y Ricardo Piglia.
Authors: Macedo Rodríguez Alfonso 
Published: October 2018

Este artículo establece nuevas conexiones entre la narrativa de Juan José Saer y Ricardo Piglia, figuras fundamentales de la literatura argentina contemporánea, a través del análisis de algunos personajes que destacan por su activismo político radical. En sus obras, algunos personajes ficcionales son guerrilleros que representan ciertos dilemas éticos: participar violentamente contra el sistema político represor o llevar a cabo acciones intelectuales moderadas pero que representan otras formas de resistencia social. Este trabajo une ambas poéticas pero contrasta sus posiciones políticas; también se establecen algunas líneas intertextuales que contribuyen al diálogo literario que Piglia y Saer mantuvieron. Abstract: This paper establishes new links between the narrative of Juan José Saer and Ricardo Piglia, fundamental writers in contemporary Argentinian literature analyzing some characters that stand out for their radical political activism. In their texts, some fictional characters are guerrilleros that represent certain ethical dilemmas: they violently participate against the represive political system or they take moderate intellectual actions that represent another way of social resistance. This paper joins together both poetics and contrast their political stances; it also lays down some intertextual relations that contribute to the dialog that Piglia and Saer kept.
Subjetividades políticas y primer peronismo en entornos rurales.
Authors: Aznárez Carini Gala , Reynares Juan Manuel , Vargas María De las Mercedes 
Published: October 2018

Desde una perspectiva político-discursiva, en este artículo se analizan tres cartas enviadas, por parte de ciudadanos provenientes de entornos rurales sin protagonismo político relevante, al presidente Juan Domingo Perón durante su primer gobierno. Interesa indagar algunas dimensiones del fenómeno político argentino conocido como peronismo y preguntarse por la modalidad específica que asume el proceso de subjetivación política que subyace en estas misivas desde una redefinición de la categoría de populismo. Así, se analiza más específicamente cómo se constituyen las posiciones de enunciación de los individuos, los desplazamientos y disrupciones que el discurso oficial produjo sobre las temáticas tratadas allí y el vínculo establecido entre aquellos que escriben y el gobierno peronista. Este hallazgo permite discutir con algunas de las miradas canónicas del peronismo histórico sobre una presunta distinción, en ese periodo, entre una etapa beligerante y otra pacificadora que se habría verificado hacia fines de los años cuarenta.Abstract: Based on a political-discursive perspective, this paper analyses three letters sent by rural citizens with no political protagonism to President Juan Domingo Perón during his first tenure. We aim to investigate some dimensions of the Argentinean political phenomenon known as Peronismo. Parting from a theoretical redefinition of populism, we look into the specific modality of the political subjectivation process that underlies in these letters. Thus, we analyse in detail the way writer’s individual enunciation stands take form, the shifts and disruptions the official narrative caused on them, and the links between the authors and Peronista government. Our contribution opens a discussion with canonical perspectives of historical peronismo which suggest in those days a so called existence of a differentiation of a belligerent stage and a pacifying one in the late 40s.
Reactions of Nonprofit Monitors to Financial Reporting Problems
Authors: Burks Jeffrey J. 
Published: October 2018

ABSTRACT
This study investigates how those in charge of monitoring nonprofits—donors and boards of directors—react to disclosure of financial reporting problems (accounting errors and internal control deficiencies). I find that donations tend to fall following disclosure of severe errors and control deficiencies. Furthermore, donations fall following errors only when they are disclosed in the report that is most widely accessible by donors. Turnover of chief financial officers (CFOs), representing a possible response of boards to financial reporting problems, increases following disclosure of errors. CFO turnover is not robustly related to control deficiencies. Overall, the results are consistent with donors and boards being willing to take action in response to concerns about financial reporting quality, thus indicating that they consider financial reporting important and that they act on signals of low quality. Interviews with nonprofit board members suggest that the value of error-free financial reporting derives less from the decision usefulness of the information and more from demonstrating that the organization is competent and trustworthy.

Violencia en la práctica médica en México: un caso de ambivalencia sociológica
Authors: Castro Roberto , Villanueva Lozano Marcia 
Published: October 2018

Clasificamos las diversas formas de violencia a las que están expuestos los médicos en su formación y práctica profesional. Violencia externa es la que se ejerce por actores ajenos al campo médico y violencia interna, la que se ejerce entre médicos, personal de salud y pacientes. Esta última puede ser hegemónica (si procede de las estructuras de poder vigentes) o contrahegemónica (si las desafía). La hipótesis es que los médicos mantienen una relación de ambivalencia sociológica frente a las formas de violencia a las que están expuestos en su desempeño cotidiano. Ello les permite ser muy críticos ante la violencia externa, y al mismo tiempo naturalizar o aceptar como parte de la profesión la violencia interna hegemónica. Se documenta con diversos ejemplos empíricos el funcionamiento de esta ambivalencia.
