One Step Production of High-performance Sandwich Components
Authors: Hopmann Ch. , Wagner R. , Fischer K. , Böttcher A.
Published: September 2018

The combined PU spray and wet pressing process allows the manufacture of parts with high lightweight potential. The process can be used for the production of sandwich parts with compact continuous fiber reinforced PU outer layers and a process integrated formation of the foam core. Compared with established production processes for structural sandwich parts, the integration of the foam core formation in a wet pressing process is highly efficient and economical especially for complex structural parts.
Microstructure Measurement and Microgeometric Packing Characterization of Rigid Polyurethane Foam Defects
Authors: Xu Jie , Wu Tao , Zhang Jianwei , Chen Hao , Sun Wei , Peng Chuang
Published: September 2018

Streak and blister cell defects pose extensive surface problems for rigid polyurethane foams. In this study, these morphological anomalies were visually inspected using 2D optical techniques, and the cell microstructural coefficients including degree of anisotropy cell circumdiameter, and the volumetric isoperimetric quotient were calculated from the observations. A geometric regular polyhedron approximation method was developed based on relative density equations, in order to characterize the packing structures of both normal and anomalous cells. The reversely calculated cell volume constant, Cc, from polyhedron geometric voxels was compared with the empirical polyhedron cell volume value, Ch. The geometric relationship between actual cells and approximated polyhedrons was characterized by the defined volumetric isoperimetric quotient. Binary packing structures were derived from deviation comparisons between the two cell volume constants, and the assumed partial relative density ratios of the two individual packing polyhedrons. The modelling results show that normal cells have a similar packing to the Weaire-Phelan model, while anomalous cells have a dodecahedron/icosidodecahedron binary packing.
Rapid antidepressant effects of deep brain stimulation of the pre-frontal cortex in an animal model of treatment-resistant depression
Authors: Papp Mariusz , Gruca Piotr , Lason Magdalena , Tota-Glowczyk Katarzyna , Niemczyk Monika , Litwa Ewa , Willner Paul
Published: September 2018

Background:

A significant proportion of depressed patients fail to respond to treatment with antidepressant drugs. Such patients might nonetheless respond to deep brain stimulation of the prefrontal cortex. Deep brain stimulation has also been shown to normalize behaviour in the chronic mild stress (CMS) model of depression. However, these studies have involved animals that are in general treatment responsive. Thus, this is not the ideal situation in which to investigate how deep brain stimulation is effective where antidepressant drugs are not.

Aims:

Here, we studied the behavioural effects of deep brain stimulation in treatment-resistant animals.

Methods:

Wistar rats were exposed to chronic mild stress and concurrent treatment with saline or one of three antidepressant drugs, imipramine, citalopram and venlafaxine. Individuals were selected from the CMS-exposed drug-treated groups that had failed to increase their sucrose intake by week 5 of drug treatment. All animals were then implanted with deep brain stimulation electrodes in the ventro-medial prefrontal cortex, and tested for sucrose intake and in the elevated plus maze and novel object recognition test, following 2 × 2 h of deep brain stimulation.

Results:

The selected drug-treated animals were found to be antidepressant-resistant in all three tests. With a single exception (sucrose intake in imipramine-treated animals), deep brain stimulation reversed the anhedonic, anxiogenic and dyscognitive effects of CMS in all four conditions, with no significant differences between saline- and drug-treated animals.

Conclusions:

These data provide a proof of principle that deep brain stimulation of the prefrontal cortex can be effective in a rat model of resistance to chronic antidepressant treatment, replicating the clinical effect of deep brain stimulation in treatment-resistant depression.
Behavioural Intention to the Use of Mobile Banking in Kerala: An Application of Extended Classical Technology Acceptance Model
Authors: Saji T. G. , Paul Deepa
Published: September 2018

This research, using an extended version of classical technology acceptance model (TAM), investigates the factors influencing the adoption behaviour of mobile technology in banking. Survey data on 214 banking customers in Kerala were analysed under a structural equation modeling (SEM) framework and the results confirm the usefulness of TAM in predicting mobile banking adoption behaviour. The exogenous constructs from the original TAM, perceived usefulness (PU), and perceived ease of use (PEU) along with two additional constructs in the extended model, perceived credibility (PC) and perceived self-efficacy (PSE), emerged out as significant antecedents of the behavioural intention of customers, especially of an educated youth, towards the use of mobile technology in banking. Findings ultimately suggest that accurate and consistent identification of customers’ propensity to adopt technology banking provides strategic map to banks from emerging markets to grow in underserved markets, achieve omni-channel presence, and disrupt value chain components.

Authors: Zhorzel Sven , Busch Albert , Trenner Matthias , Reutersberg Benedikt , Salvermoser Michael , Eckstein Hans-Henning , Zimmermann Alexander
Published: September 2018

Purpose:

Outcomes of open iliac artery repair (OIR) and endovascular iliac artery repair (EVIR) were compared at a tertiary referral vascular center.

Methods:

From 2004 to 2015, all patients treated for isolated iliac artery aneurysms (IAAs) were retrospectively identified, and patient records and computed tomography (CT) scans were analyzed. The primary end point was overall survival; secondary end points were 30-day mortality and morbidity and freedom from reintervention. For follow-up, data from outpatient visits and CT scans following a standard surveillance protocol were used.

Results:

A total of 106 IAAs in 94 patients were treated (mean follow-up: 35.7 months; 66 OIR; 40 EVIR). Six (15%) aneurysms from the EVIR group and 4 (6.1%) from open-operated IAA presented in the state of rupture. There was no difference in overall survival between EVIR and OIR ( P = .14). In multivariable analysis, higher risk of death was associated with ruptured IAA (rIAA; hazard ratio [HR]: 40.44, 95% confidence interval [CI]: 2.05-796.18; P = .02) and coronary heart disease (HR: 11.07, 95% CI: 1.94-63.36; P < .01). The 30-day mortality was 1.9% overall (0% OIR, 5.0% EVIR, P = .27), but there were no differences between OIR and EVIR in 30-day morbidity ( P = .11). Freedom from reintervention was higher for OIR than for EVIR ( P < .01). In multivariable analysis, a higher reintervention rate was seen in EVIR (HR: 10.80, 95% CI: 2.20-53.01; P < .01) and in rIAA (HR: 12.02, 95% CI: 1.31-111.11; P = .03).

Conclusion:

Iliac artery aneurysmss can be safely and effectively treated by EVIR or OIR regarding 30-day morbidity, mortality, and long-term survival, although freedom from reintervention is significantly lower after EVIR.

Published: September 2018

Background and purpose

This retrospective study evaluates the safety and mid-term and long-term effectiveness of stent-assisted coil embolization of anterior communicating artery (Acomm) aneurysms treated with the LVIS Jr stent.

Materials and methods

All patients treated with the LVIS Jr stent for Acomm aneurysms between June 2015 and March 2018 were included in the analysis. Details of the procedure’s periprocedural adverse events, immediate aneurysm occlusion rates, and clinical and angiographic follow-up assessment were collected.

Results

A total of 25 patients with 25 aneurysms were included. Eighteen aneurysms were found incidentally. Seven patients presented with seven ruptured aneurysms: Six were remotely ruptured and one acutely ruptured. Twenty-four patients were treated successfully and one technical failure is reported. The parent arteries measured 1.4 mm to 2.9 mm in diameter (mean, 2.3 mm). Intraprocedural thromboembolic complications occurred in two patients (8%) and an intraoperative aneurysm rupture in one patient (4%). Immediate complete aneurysm occlusion was noted in 18 out of 25 patients (72%). Clinical follow-up ranged from three months to 36 months (mean, 15.8 months) and the imaging follow-up ranged from two to 35 months (mean, 14.2 months). Complete aneurysm occlusion was achieved in 14 out of 20 patients (70%) at last angiographic follow-up. Of the two patients with in-stent thrombosis, one patient had an acutely ruptured aneurysm and the other patient was treated with an LVIS Jr stent in a Y configuration. Neurological morbidity and mortality rate were 0%.

Conclusions

Complex, wide-necked Acomm aneurysms can be effectively treated with stent-assisted embolization using LVIS Jr stents.

Published: September 2018

Background

A subset of patients with functional defecation disorders have predominance of the puborectalis muscle (PRM) on three‐dimensional high definition anorectal manometry (HDARM), known as paradoxical puborectalis syndrome (PPS). The aim of this study was to assess clinical and manometric differences between patients with and without PPS.

Methods

A total of 227 women with functional defecation disorders undergoing HDARM between December 2012 and October 2016 at a single center were included in this study. All completed the Rome III constipation module and Pelvic Floor Distress Inventory 20 (PFDI‐20).

Results

Eighty‐seven out of 227 women had a 3D pressure topographic profile consistent with PPS. They had higher mean PDFI‐20 scores for straining and incomplete evacuation symptoms than those without PPS. In addition, they demonstrated higher mean resting anal pressure, a more negative mean anorectal pressure differential, and a greater proportion with prolonged balloon expulsion test. These findings were more pronounced in a subgroup of 58 PPS patients with a distinct pattern of both posterior and posterolateral wall indentation.

Conclusion

Among female patients with functional defecation disorders, those with PPS demonstrated clinical and manometric differences compared to those without PPS. These differences may be driven by predominant posterolateral wall indentation in a subgroup of PPS patients.
Learning From Your Children: Multiracial Parents’ Identifications and Reflections on Their Own Racial Socialization
Authors: Song Miri
Published: September 2018

Despite the growing importance of racially mixed people and families in Britain, in demographic terms, relatively little is known about the life experiences of multiracial people at disparate stages of their lives, as most studies focus on their identifications at one point in time. In fact, we know very little about how multiracial people are influenced by the life-changing events of partnering and becoming a parent: How may multiracial people’s racial identities be shaped by the experiences of having children? To date, the extant literature has focused on how parents in interracial unions racially identify their multiracial children or how multiracial individuals identify themselves, especially in adolescence and young adulthood. However, little is known of what happens when mixed people themselves become parents or how their own sense of selves may be impacted by their second-generation mixed children and their children’s own identifications and experiences.
Coercing Women's Behavior: How a Mandatory Viewing Law Changes Patients' Preabortion Ultrasound Viewing Practices
Authors: Kimport Katrina , Johns Nicole E. , Upadhyay Ushma D.
Published: September 2018

Over the past two decades, US states have enacted legislation regulating ultrasound scanning in abortion care, including mandating that abortion patients view their ultrasound image. Legal scholars have argued that, by constructing ultrasound viewing as a necessary part of patients' abortion decision making, these laws aim to control and constrain how women make personal decisions about their bodies and parenthood. To date, however, the discussion of the impact of ultrasound viewing laws on women's decisional autonomy has occurred in the abstract. Here, we examine the effect of Wisconsin's mandatory ultrasound viewing law on the viewing behavior of women seeking care at a high-volume abortion-providing facility. Drawing both on chart data from patients before and after the law went into effect and on in-depth interviews with women subject to the mandatory viewing law, we found that the presence of the law impacted patients' viewing decision making. Moreover, we documented a differential effect of the law by race, with larger impacts on the viewing behavior of black women compared with white women. Our findings call for renewed attention to the coercive power of laws regulating abortion on a macrolevel, investigating not only how they affect individuals' behavior and experience but also which individuals are impacted.

Published: September 2018

Objective

To report acute hematological toxicity (HT) in patients receiving post-operative bowel sparing intensity-modulated radiotherapy (IMRT) and cisplatin and its dosimetric predictors.

Methods

Clinical database of Phase III trial (NCT01279135), that randomized patients to post-operative conformal or intensity modulated radiation therapy, was searched to select patient strata that received bowel sparing IMRT (50 Gy/25#/5 wks) and concurrent cisplatin (40 mg m–  2). Pelvic bone marrow (BM) was retrospectively delineated in two sets: whole bone (WB), and freehand (FH) inner cavity of bone. Dose volume histograms (DVH) of BM were obtained. Receiver operating characteristic (ROC) curve identified DVH thresholds that predicted for Grade≥ II HT with highest specificity. Univariate and multivariate analysis was performed.

Results

Overall 75 patients received concurrent cisplatin. Grades I–V HT was observed in 38.7%, 42.7%, 14.7%, 0%, and 0% patients, respectively. Grade ≥ II leukopenia, neutropenia, anemia, and thrombocytopenia were observed in 26%, 40%, 26.5%, and 1.4% respectively. None of the HT resulted in treatment break. On univariate analysis, whole pelvis+ lumbar FH V30 >55% & V40>35%, whole pelvis WB and FH V40 > 35%, and lower pelvis WB and FH V40 >20% correlated for Grade ≥ II leucopenia and neutropenia. None of the BM dose volume constraints predicted for overall HT or neutropenia on multivariate analysis.

Conclusion

The IMRT arm of NCT01279135 (PARCER study) that employed strict bowel constraints had unintentional but desirable BM sparing. None of the BM subvolume DVH parameters could be validated on multivariate analysis.

Advances in knowledge

The prospective study reports feasibility of bone marrow sparing with bowel sparing post-operative pelvic IMRT and concurrent chemotherapy for cervical cancer. The present study reports low incidence of hematological and gastrointestinal toxicity during post-operative chemoradiation with IMRT. As both whole bone and freehand pelvis BM contours predicted for HT, hence an easier method of whole bone contouring should continue to be used till further validation of more specific BM subvolumes becomes available. The study results highlight the need for further research into dose volume constraints during post-operative IMRT.

Quais os modos de ser garota e garoto na juventude? Que identidades esses jovens têm construídos na ocupação dos diversos espaços do recreio? Como tem sido essa ocupação: negociada, conflituosa ou tácita? Este artigo é parte da pesquisa de mestrado, em andamento, sobre a relação entre juventude, consumo e gênero, com enfoque no cotidiano da escola, sobretudo na observação da ocupação dos espaços do recreio de garotos e garotas com idades entre 13 e 14 anos de idade, da turma do oitavo ano do Ensino Fundamental II, da “Escola da Praia”: uma escola da rede católica de ensino, na Zona Sul do Rio de Janeiro, próximo ao mar. Tomamos o referencial de Bakhtin, no que diz respeito à “dimensão alteritária” e, quanto a autores que discutem identidade, nos fundamentaremos basicamente em dois: Jonê Carlão Baião (2006), por auxiliar na compreensão das identidades como sendo constantemente negociadas, uma vez que são flexíveis e variáveis e; Guacira Lopes Louro (1997), por falar que as identidades estão sempre se construindo.  Utilizamos como metodologia a observação com registros de áudio e vídeo de uma câmera e a narrativa descritiva dos dados coletados.

Published: September 2018

Inserida no discurso contemporâneo que salienta a importância do fazer pedagógico que se diz inovador porque mediado pela tecnologia, o objetivo geral desta pesquisa é o de buscar compreender os impactos do uso da rede social Facebook no desenvolvimento de linguagem dos alunos. Considerando que os documentos oficiais para a educação no Paraná trazem, de modo implícito ou explícito, o pressuposto de que as práticas discursivas materializadas em gêneros textuais/discursivos podem ser considerados como um instrumento psicológico que media as ações de linguagem (BRONCKART, 2006), alicerçamos esta investigação pela premissa de cunho didático de que os gêneros de texto devem ser o centro do processo de ensino de produção e compreensão. Nessa perspectiva, buscamos validar o Comentário de Facebook como gênero do discurso capaz de contribuir para o desenvolvimento das capacidades de expressão oral e escrita de alunos do ensino fundamental de uma escola pública.  Esta pesquisa se fundamenta nos aportes teóricos e metodológicos oriundos do interacionismo sociodiscursivo, sobretudo nos trabalhos desenvolvidos sobre a questão do ensino-aprendizagem de gêneros textuais (SCHNEUWLY; DOLZ, 2004; 2009).  Os resultados indiciam diversos aspectos que fazem das redes sociais, em especial o gênero Comentário do Facebook um instrumento que pode mediar ações formativas que tenham como objetivo o desenvolvimento de capacidades de linguagem.

Published: September 2018

Solid Oxide fuel Cells (SOFCs) are considered to be one of the most promising energy conversion devices that have several advantages such as high efficiency, system compactness and low environmental pollution. In the present investigation La0.65Sr0.3MnO3 (LSM-1) and La0.8Sr0.2MnO3 (LSM-2) nanoceramic powders were prepared by citrate-nitrate route of auto-combustion with citrate to nitrate (c/n) ratio 0.50 to see the effect of these cathode powders on the performance of SOFC cells. The as prepared powder were calcined at 900oC for 4hrs using the Thermolyne 47900 furnace to remove carboneous residues and characterized them using SEM / EDS, XRD, TGA techniques and their results are presented . From calculations using Debye Scherrer’s equation, the average crystallite size of the powders were found to be around 16nm. The SEM indicates the particle sizes are within the range of around 200nm.The surface area of the calcined LSM-2 powder was found to be ~21m2/g. The TGA studies indicate the completion of combustion since there was no further weight loss after reaching temperature of ~ 650oC.

Also, Electrochemical characterization of LSM cathode powders were carried out by coating these powders (as cathode functional layer CFL-Bottom and current collector layer CL- Top) using Screen printing on the SOFC half cells (NiO-YSZ+YSZ) procured from CGCRI, Kolkata, India with a cell size of 16mm dia x1.6mm and tested these cells with H2-O2 at 750-800oC with the flow rates of 100-200 sccm. The results of the performances of single cells are presented in this paper. The Current density and powder density values obtained are 0.80A/cm2 (at 0.7V) and 0.55 W/cm2 at 800oC with 200 sccm of hydrogen and oxygen respectively. The area surface resistance (ASR) values obtained were ~0.50 Ωcm2 at 0.7V at 800oC.

Published: September 2018

Daphne gnidium L. (DGL), a plant known to be rich source of polyphenols, a naturally occurring class of antioxidants, was tested for its ability to play the role of primary and secondary brighteners for electrodeposition of nickel, as a replacement for synthetic brighteners such as glycerol and formaldehyde. A simple and convenient approach was adapted consisting in adding an accurate amount of powdered leaves of Daphne gnidium L. (DGLP) or Daphne gnidium L. leaves extract (DGLE), to the Watts bath, to play the role of brightening agents. Cyclic voltammetry studies revealed that DGLP could inhibit the reaction of nickel reduction and improve the quality of the deposits as efficiently as glycerol and formaldehyde. SEM analyses showed that the micro-cracks decreased and sometimes disappeared from nickel deposits prepared in the presence of DGLP as a brightener. The results of this study show that DGL can be used satisfactorily, with minimum operations as a brightening agent for nickel electrodeposition. The key idea of direct immersion of DGLP in the Watts bath, aimed to the replacement of synthetic brighteners and the reduction of the overall cost of nickel electrodeposition.
Corrosion Inhibition of a Gas Sparged Copper Cylinder in a Solution of NaCl and Na2S by Using 4-Amino-4H-1,2,4-triazole as Corrosion Inhibitor
Authors: Al-Shahrani Saad Said
Published: September 2018

Most of previous investigations for corrosion inhibition of copper using triazole derivatives were carried out in stagnant conditions and mainly in presence either NaCl or Na2S. The main aim of this work is to investigate the performance of one of triazole derivatives namely, 4-Amino-4H-1,2,4-triazole (AHT) on improving the corrosion resistance of gas sparged copper parts in a solution comprised of NaCl and Na2S with different propotions. The potentiodynamic technique was used for investigating the effect of different variables on the corrosion rate of gas sparged copper such as gas velocity, initial S-2 concentration, gas sparged copper cylinder diameter, and initial AHT inhibitor concentration. The results show that the %improvement in corrosion resistance depends mainly on two main parameters, gas flow rate and amount of AHT inhibitor added. For lower gas velocities 0.07 cm/s the %improvement ranges from 6 to 22%, while for higher gas rate 0.35 cm/s it ranges from 2 to 7% depending on the amount of inhibitor added. The activation energy of the reaction was found to increase by approximately 20% by addition of the inhibitor up to 10ppm.

Published: September 2018

Some binary ferrites having molecular formula, MnxFe3-xO4 (0 ≤ x ≤ 1.5) have been synthesized by a simple and cost effective egg white sol-gel route. In each preparation, nitrates of constituent metal were taken as starting materials and egg white as gelling agent. The material, thus obtained was altered in the form of film electrode on the pre-treated Ni- support using an oxide-slurry painting tech-nique and investigated as electrocatalysts for the oxygen evolution reaction in KOH solutions. The study showed that Mn-substitution in the base oxide matrix influences the electrocatalytic activity of the material significantly and found to be greatest with 0.5 mol Mn-substitution. The reaction order has been found to be approximately unity with respect to OH¯ concentration. The Tafel slope values at low potential ranged between ~ 52 and ~ 65 mVdecade-1. The thermodynamic parameters namely, standard apparent electrochemical enthalpy of activa-tion (), standard enthalpy of activation () and standard entropy of activation () for the oxygen evolution reac-tion (OER) have also been determined. It has been observed that and values decreased with Mn-substitution in the Fe3O4 lattice. This decrease inandwas found to be greatest with 0.5 mol Mn. Thevalues were also found to be highly negative varying between ~ - 185 and – 211 J deg-1 mol-1.

Published: September 2018

This paper focuses on the dilution agent effect onto interactions between methylene blue (MB) and DNA using carbon fiber microelectrode (CFME) based DNA biosensor. In this study, designed CFME based DNA biosensor was successfully carried out considering the effect of probe dilution agent (e.g. 3-mercaptopropionic acid) against proposed hybridization mechanism types. The voltammetric signals of MB were measured at bare CFME, single-stranded DNA (ssDNA)-modified CFME and double-stranded DNA (dsDNA)-modified CFME by means of square wave voltammetry (SWV). The electrochemical parameters for MB on binding to DNA onto single CFME in the solution and at the electrode surface were described. This study shows that probe dilution agent is a significant factor to determine the type of DNA hybridization mechanisms.

In this study, zinc oxide nanostructures were grown on gold-coated silver wires by hydrothermal method. Multiple analyses on these nanostructures were performed to understand the structure and optical properties of zinc oxide on Au-plated silver wires, Owing to the Au-coated layer, ZnO nanorods could appear rather than ZnO nanoflakes on pure silver wires. Moreover, The deposited gold layer could vary zinc oxide nanostructures to nanorods The multiple analysis shows that lying flat ZnO structures with weak (002) crystalline structures and more defects could appear on the silver wire rather than ZnO nanostructures on pure silver wires.
Controlled Synthesis of ZnO Nanostructures by Electrodeposition without Any Pretreatment and Additive Regent
Authors: Xi Xin , Yang Chao , Liu Lei , Zhu ShiChao , Cao Haicheng , Zhao Lixia
Published: September 2018

ZnO nanostructures have been fabricated using electrodeposition method without any additive reagent and nucleation-layer. The influences of the applied voltage, temperature, electrolyte concentration, and time on the nanostructures of ZnO have been investigated using cyclic voltammety (CV), X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The result shows that the 1-dimensional (1D) nanostructures tend to be formed at lower voltage and electrolyte concentration, while 2-dimentional (2D) nanostructures can be easily obtained at higher voltage and concentration. Although increasing temperature is helpful to grow 1D nanostructures, but excessive high temperature will destroy the ZnO nanostructures because of the high solubility of ZnO. Furthermore, we reveal the mechanism of the formation of ZnO nanostructures mainly depends on the competition between the hydroxylation and dehydration reaction. Our work is helpful for developing the photocatalytic and photodetection applications using different ZnO nanostructures.

In der Vorrömischen Eisenzeit finden europaweit Prozesse statt, die einen grundlegenden Wandel gesellschaftlicher ebenso wie wirtschaftlicher und vermutlich politischer Strukturen beinhalten. Regional jedoch scheinen sich diese Prozesse zu unterscheiden, so dass eine einheitliche Entwicklung sich nur mäßig abzeichnet und die Prozesse auf einer europäischen Skala teils kaum verstanden werden können. Dieser Beitrag greift den Hallstatt/Latène- und den Jastorfkreis heraus, um den Kontrast zwischen zwei unterschiedlichen Regionen näher zu beleuchten und die egalitäre Gesellschaft des Nordens der streng hierarchischen Gesellschaft des Hallstattkreises gegenüberzustellen. Die Begriffe „Hierarchie“, „Territorium“ und „Zentralort“ spielen in der Diskussion eine wesentliche Rolle und werden diskutiert, insbesondere, da sie bislang eher unkritisch verwendet wurden. Es erweist sich, dass eine klare Terminologie unerlässlich ist und dass die traditionellen Interpretationsmuster verdeckte Prämissen enthalten, die es zu hinterfragen gilt. Zwei Fallstudien zur Territorialität und zur Hierarchie, eine in Südwest- und eine in Norddeutschland, überprüfen die gängigen Interpretationsmuster und legen nahe, dass der Kontrast zwischen den beiden Regionen weniger ausgeprägt ist, als eine oberflächliche Beurteilung zeigt. Hieraus schließen die Autoren nicht auf gleiche Gesellschaften mit unterschiedlicher archäologischer Ausprägung, sondern, dass das Verhältnis der Regionen, insbesondere auf einer europäischen Ebene, neu und kritisch überdacht werden muss.
Immediacy, counter-expectation, and grammatical marking: Intransitive constructions with an accusative clitic in Galician/Galego
Authors: Rivas Javier
Published: September 2018

We provide a usage-based approach to the construction [locative deictic + accusative clitic + intransitive verb] found in Galician/Galego. In this construction, the intransitive verb and the accusative clitic agree in person and number and, in the case of the clitic, also in gender with the referent of the clitic, as in, for example, aí a está (lit.: ‘there her is/there she is’)/aí as están (lit.: ‘there them are/there they are’). A corpus-based analysis of this construction shows that it presents skewed grammatical patterns in terms of frequency of occurrence. This grammatical skewing reveals that the construction emerges from an interactional usage pattern in which speakers shift from a displaced to an immediate mode of speaking to present a counter-expected situation. The construction is also exploited in narratives in order to create a quality of immediacy for displaced events. Our usage-based analysis also reveals a family of constructions — some more schematic, others more specific; some more entrenched, others more novel — that emerge from the repetition of local usage patterns through which speakers/narrators express immediacy and counter-expectation.

KNOWING THAT CRITICAL SELFREFLECTION IS AN ESSENTIAL PART OF CONTINUAL DEVELOPMENT, HOW DO STRENGTH AND CONDITIONING COACHES (SCCS) EFFECTIVELY QUESTION THEIR PRACTICES AND BASIC ASSUMPTIONS? THE SOCIAL CONSTRUCTION OF KNOWLEDGE THEORY IS A SOCIAL THEORY THAT HAS RICH POTENTIAL FOR SCCS' DEVELOPMENT BECAUSE IT ENABLES THEM TO MAKE JUDGMENTS ABOUT THE EFFECTIVENESS OF THEIR KNOWLEDGE, BELIEFS, AND PRACTICES. IN DESCRIBING THE SOCIAL CONSTRUCTION OF SCCS' KNOWLEDGE AND PRACTICE, THIS ARTICLE MAKES CLEAR HOW THE PRODUCTION OF THE IDEAL SPORTING BODY COULD BE UNDERSTOOD MORE IN RELATION TO DOMINANT CAPITALIST DISCOURSES THAN SPORTING EXCELLENCE, USING RENOWNED SOCIAL CONSTRUCTION THEORIST, MICHEL FOUCAULT.

Borderline personality disorder (BPD) and alcohol use disorder often cooccur, yet we know little about risk processes underlying this association. We tested two mechanistic pathways linking BPD symptoms and alcohol-related problems. In the “affective pathway,” we hypothesized that BPD symptoms would be associated with alcohol-related problems through affective instability and drinking to cope. In the “sensation-seeking pathway,” we proposed that BPD symptoms would be related to alcohol-related problems through sensation seeking and drinking to enhance positive experiences. We tested a multiple mediation model using age-18 cross-sectional data from the Pittsburgh Girls Study. Results supported both pathways: BPD symptoms had an indirect effect on alcohol-related problems by (1) affective instability and coping motives (β = .03, p < .05), and (2) sensation-seeking and enhancement motives (β = .02, p < .05). These results highlight coping and enhancement drinking motives as possible mechanisms that explain co-occurrence of BPD symptoms and alcohol-related problems in young females.
