Styles and Goals: Clarifying the Professional Identity of Divorce Mediation
Authors: Baitar Rachid , Buysse Ann , Brondeel Ruben , De Mol Jan , Rober Peter 
Published: October 2013

AbstractIn contrast to mediation outcome studies, there is a lack of research on mediation processes. In response, this article explores mediators' styles and goals and their determinants, such as the mediators' professional background and client characteristics. Survey data of 359 divorce professionals were analyzed with the use of multiple regression analyses. Results showed that styles and goals are predominantly determined by professional‐related characteristics. Lawyer mediators and mental health mediators diverged in advisory and interest‐based styles but were unified in all goals we studied. The goals, self‐determination, advocacy, and processing emotions differentiated mediation from law and mental health practice. Implications are discussed.

Published: October 2013

AbstractThis article describes marital mediation, a process that uses established mediation techniques to improve relationships, and its similarities to and differences from marital counseling. It also looks at the process from a psychological perspective, exploring aspects of the methodology that may explain its effectiveness in cases where counseling has failed. Finally, the need for marital mediation is discussed.
Testing for intraspecific postzygotic isolation between cryptic lineages ofPseudacris crucifer
Authors: Stewart Kathryn A. , Lougheed Stephen C. 
Published: October 2013

AbstractPhenotypically cryptic lineages appear common in nature, yet little is known about the mechanisms that initiate and/or maintain barriers to gene flow, or how secondary contact between them might influence evolutionary trajectories. The consequences of such contact between diverging lineages depend on hybrid fitness, highlighting the potential for postzygotic isolating barriers to play a role in the origins of biological species. Previous research shows that two cryptic, deeply diverged intraspecific mitochondrial lineages of a North American chorus frog, the spring peeper (Pseudacris crucifer), meet in secondary contact inSouthwesternOntario,Canada. Our study quantified hatching success, tadpole survival, size at metamorphosis, and development time for experimentally generated pure lineage and hybrid tadpoles. Results suggest that lineages differ in tadpole survival and thatF1hybrids may have equal fitness and higher than average mass at metamorphosis compared with pure parental crosses. These findings imply hybrid early life viability may not be the pivotal reproductive isolation barrier helping to maintain lineage boundaries. However, we observed instances of tadpole gigantism, failure to metamorphose, and bent tails in some tadpoles from hybrid families. We also speculate and provide some evidence that apparent advantages or similarities of hybrids compared with pure lineage tadpoles may disappear when tadpoles are raised with competitors of different genetic makeup. This pilot study implies that ecological context and consideration of extrinsic factors may be a key to revealing mechanisms causing negative hybrid fitness during early life stages, a provocative avenue for future investigations on barriers to gene flow among these intraspecific lineages.
Work Satisfaction, Causes, and Sources of Job Stress and Specific Ways of Coping: A Case Study of White‐Collar Outsourcing Service Employees
Authors: Seklecka Luiza , Marek Tadeusz , Lacala Zofia 
Published: October 2013

AbstractThis study investigated work‐related stresses in the business outsourcing service environment. Eighty‐six white‐collar professionals who occupied low‐level managerial positions in a business accounting outsourcing company took part in the field study. The derived scales for the sources of stress, work satisfaction, and coping with stress had different structure than those contained in the original occupational stress indicator scale of Cooper, Sloan, and Williams (1988). The study results also illustrate that the observed sources of work stress perceived by white‐collar employees of the outsourcing firm are unique to this occupational group and specific to this sector of business activity. Future research efforts will focus on comparative analysis of work stress in outsourcing companies across different cultures. © 2013 Wiley Periodicals, Inc.
The Effects of 3 Years of Calcium Supplementation on Common Carotid Artery Intimal Medial Thickness and Carotid Atherosclerosis in Older Women: An Ancillary Study of the CAIFOS Randomized Controlled Trial
Authors: Lewis Joshua R , Zhu Kun , Thompson Peter L , Prince Richard L 
Published: October 2013

ABSTRACT

Calcium is an essential nutrient for skeletal health; however, it has been suggested that supplemental calcium may be associated with adverse cardiovascular effects, raising widespread concern about their use. One suggested mechanism is via increasing carotid atherosclerosis, however few randomized controlled trials (RCT) of calcium supplements have assessed these mechanisms. The calcium intake fracture outcome study (CAIFOS) was a 5-year RCT (1998 to 2003) of 1.2 g of elemental calcium in the form of calcium carbonate in 1460 elderly women. An ancillary study of 1103 women assessed common carotid artery intimal medial thickness (CCA-IMT) and carotid atherosclerosis at year 3 (2001). The effects of supplementation were studied in intention-to-treat (ITT) and per-protocol (PP) analyses before and after adjustment for baseline cardiovascular risk factors. The mean age of participants at baseline was 75.2 ± 2.7 years. In ITT analyses, women randomized to calcium supplementation had no difference in multivariable-adjusted mean CCA-IMT (calcium 0.778 ± 0.006 mm, placebo 0.783 ± 0.006 mm, p = 0.491) and maximum CCA-IMT (calcium 0.921 ± 0.007 mm, placebo 0.929 ± 0.006 mm, p = 0.404). Women randomized to calcium did not have increased carotid atherosclerosis (calcium 47.2%, placebo 52.7%, p = 0.066). However, in women taking at least 80% of the supplements, a significant reduction in carotid atherosclerosis was observed in unadjusted but not in multivariate-adjusted models (p = 0.033 and p = 0.064, respectively). Participants in the highest tertile of total calcium (diet and supplements) had reduced carotid atherosclerosis in unadjusted and multivariable-adjusted analyses compared with participants in the lowest tertile (odds ratio [OR] = 0.67 [95% confidence interval (CI) 0.50–0.90], p = 0.008, and OR = 0.70 [95% CI 0.51–0.96], p = 0.028, respectively). In conclusion, these findings do not support the hypothesis that calcium supplementation increases carotid artery intimal medial thickness or carotid atherosclerosis, and high calcium intake may reduce this surrogate cardiovascular risk factor. © 2014 American Society for Bone and Mineral Research.
Numerical assessment of the combination of subgridding and the perfectly matched layer grid termination in the finite difference time domain method
Authors: Cuyckens Thomas , Rogier Hendrik , De Zutter Daniel 
Published: October 2013

SUMMARYThe finite‐difference time‐domain (FDTD) method is one of the well‐established numerical techniques to model electromagnetic problems. In order to be able to efficiently include the finer geometrical details, subgridding is used to avoid the use of a fine mesh over the whole region of interest. Our work builds on and extends the systematic framework provided by Chilton in his PhD (H‐refinement, P‐refinement, and T‐refinement strategies for the FDTD method developed via finite element principles, Ohio State University, 2008).A crucial element of the FDTD method is the termination of the grid in an absorbing boundary condition. With the invention of the perfectly matched layer (PML) by Bérenger, this PML is now the standard absorbing boundary condition allowing very low reflection, even when positioned close to scatterers.In this contribution, the PML is first included into the earlier mentioned subgridding framework. Next, the interaction between the subgridded problem and the (subgridded) PMLs is studied. Therefore, different (geometrical) subgridding strategies for the PML are considered. We numerically investigate the effect of these strategies by determining the reflection of a point source caused by the PML. It becomes possible to not only determine the general reflection level, but also to pinpoint the precise source of the reflections. The conclusion of this study is that important reflections are found originating from the corner points of the PML (as expected) but these reflections worsen when grid nonuniformities are present because of subgridding. Hence, the combination of subgridding and PML should be handled with great care. Copyright © 2013 John Wiley & Sons, Ltd.
Numerical simulation of impact behaviour of structures with response adapted to the intensity of shock
Authors: Noversa M. , Peixinho N. 
Published: October 2013

AbstractThis study presents an alternative approach for the absorption of impact energy that uses the internal pressurization of structures in the framework of a crash‐adaptive response. Numerical simulations were conducted on axial impact of thin‐walled tubular structures with circular cross section that serve as an approximation to a front crash box of a motor vehicle. The main objective of this work consists in studying the effect of internal pressurization of tubular structures in a crashworthiness application, as well as the possibility to obtain a reduction in wall thickness thus improving weight efficiency. A numerical study is presented for an internal pressure of 20 bar and tubular structures of circular section and 1.14 mm thickness. Numerical simulations were performed recurring to LS‐DYNA explicit dynamics software while considering for the material a stainless steel alloy that is a material with interest for crashworthiness applications and manufacturing requisites due to its balance between strength, ductility and energy absorption. The results obtained allow concluding that recurring to internal pressurization it is feasible to reduce the wall thickness and have an impact resistance identical to the original while improving overall efficiency.
Effect of As, Cu and Sb impurities on performance of Pb‐Ca‐Sn grids of lead‐acid batteries

Published: October 2013

AbstractThe performance of Pb‐Ca‐Sn grids of lead‐acid batteries made from recycled lead in 4 M H2SO4 in the absence and presence of traces of Cu, As and Sb, as potential impurities in the recycling process at 0.1% level, is investigated by electrochemical methods. The study includes the effect of each impurity and impurities combined on the alloy corrodibility, the efficiency of PbO2 formation, the rate of the self‐discharge and the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). The results show that individual impurity enhances the corrosion resistance but increases the anode corrosion and the self‐discharge rate. Impurities play opposite effects on hydrogen evolution reaction and oxygen evolution reaction either individually or combined. Concerning water loss problem, the harmful effect of individual impurity on increasing oxygen evolution reaction is compensated by their suppression of hydrogen evolution reaction. The impurities combined suppress effectively both hydrogen evolution reaction and oxygen evolution reaction relative to alloy without any impurity. Sb has the highest harmful effects on oxygen evolution reaction and the self‐discharge but it is the best in the suppression of hydrogen evolution reaction. The impurities combined relatively improve the general corrosion resistance, the anode corrosion resistance and the self‐discharge. The study supports higher tolerance levels of Cu, As and Sb in Pb‐Ca‐Sn grids, especially when present combined, than the recommended levels in the industry standards.

Published: October 2013

PurposeThe limiting factor for MRI of skeletal/mineralized tissue is fast transverse relaxation. A recent advancement in MRI technology, SWIFT (Sweep Imaging with Fourier Transform), is emerging as a new approach to overcome this difficulty. Among other techniques like UTE, ZTE, and WASPI, the application of SWIFT technology has the strong potential to impact preclinical and clinical imaging, particularly in the context of primary or metastatic bone cancers because it has the added advantage of imaging water in mineralized tissues of bone allowing MRI images to be obtained of tissues previously visible only with modalities such as computed tomography (CT). The goal of the current study is to examine the feasibility of SWIFT for the assessment of the prostate cancer induced changes in bone formation (osteogenesis) and destruction (osteolysis) in ex vivo specimens.MethodsA luciferase expressing prostate cancer cell line (PAIII) or saline control was inoculated directly into the tibia of 6‐week‐old immunocompromised male mice. Tumor growth was assessed weekly for 3 weeks before euthanasia and dissection of the tumor bearing and sham tibias. The ex vivo mouse tibia specimens were imaged with a 9.4 Tesla (T) and 7T MRI systems. SWIFT images are compared with traditional gradient‐echo and spin‐echo MRI images as well as CT and histological sections.ResultsSWIFT images with nominal resolution of 78 μm are obtained with the tumor and different bone structures identified. Prostate cancer induced changes in the bone microstructure are visible in SWIFT images, which is supported by spin‐echo, high resolution CT and histological analysis.ConclusionSWIFT MRI is capable of high‐quality high‐resolution ex vivo imaging of bone tumor and surrounding bone and soft tissues. Furthermore, SWIFT MRI shows promise for in vivo bone tumor imaging, with the added benefits of nonexposure to ionizing radiation, quietness, and speed.

AbstractClear cell tubulopapillary renal cell carcinoma (CCPRCC) is a recently described rare renal malignancy that displays characteristic gross, microscopic and immunohistochemical differences from other renal tumour types. However, CCPRCC remains a very poorly understood entity. We therefore sought to elucidate some of the molecular mechanisms involved in this neoplasm by carrying out targeted next‐generation sequencing (NGS) to identify associated mutations, and in addition examined the expression of non‐coding (nc) RNAs. We identified multiple somatic mutations in CCPRCC cases, including a recurrent [3/14 cases (21%)] non‐synonymous T992I mutation in the MET proto‐oncogene, a gene associated with epithelial‐to‐mesenchymal transition (EMT). Using a microarray approach, we found that the expression of mature (n = 1105) and pre‐miRNAs (n = 1105), as well as snoRNA and scaRNAs (n = 2214), in CCPRCC cases differed from that of clear cell renal cell carcinoma (CCRCC) or papillary renal cell carcinoma (PRCC) tumours. Surprisingly, and unlike other renal tumour subtypes, we found that all five members of the miR‐200 family were over‐expressed in CCPRCC cases. As these miRNAs are intimately involved with EMT, we stained CCPRCC cases for E‐cadherin, vimentin and β‐catenin and found that the tumour cells of all cases were positive for all three markers, a combination rarely reported in other renal tumours that could have diagnostic implications. Taken together with the mutational analysis, these data suggest that EMT in CCPRCC tumour cells is incomplete or blocked, consistent with the indolent clinical course typical of this malignancy. In summary, as well as describing a novel pathological mechanism in renal carcinomas, this study adds to the mounting evidence that CCPRCC should be formally considered a distinct entity.

Published: October 2013

SUMMARYIt happened over a hundred years ago that Henry Ford introduced his famous Model T passenger car. At that time, variants and extra features were presumably rather irrelevant compared with the automobile itself, which represented the suitable response to the need of millions of new customers. Since then, a vast range of changes, functions, improvements, and so on were designed and eventually taken into mass production. Among those, in particular since the 1920s, car radios were introduced for commercial (broadcast) and professional (communications) purposes [2]. Wireless communications nowadays represent an important area for the car industry, for infotainment (information and entertainment), comfort, environmental and safety‐related services.In the field of connectivity, and specifically in the context of antennas for wireless functions, it may be of particular relevance to consider the proposition of a new European satellite technology based on S band, namely, the Digital Video Broadcasting‐Satellite Handheld standard for the forward link and the European Telecommunications Standards Institute S‐band Mobile Interactive Multimedia standard for the return link, both in S‐Band.The mentioned standards are able to provide new satellite services for mobile terminals, such as broadcasting of radio, TV, and data contents, by using Digital Video Broadcasting‐Satellite Handheld and interactive services on the return link.This paper describes the activities related to the mentioned S‐band system carried out by Calearo in the frame of the COSTARS (low COst S‐band receive/Transmit Antenna for vehiculaR applicationS) project, co‐funded by ESA‐ESTEC. In particular, the authors first briefly analyze the state of the art of the services present in the car industry from the perspective of automotive antennas, analyzing the current wireless applications and considering the amount of highly integrated functionalities already present, or being proposed. Then, the design and performances of a switchable dual polarized automotive transmission/reception antenna (COSTARS project) and usable for S‐band automotive applications are introduced. The paper also includes a description of the antenna industrialization and production line and the related measurements performed during the project. Copyright © 2013 John Wiley & Sons, Ltd.
The P2Y receptors and thrombosis
Authors: Gachet Christian , Hechler Béatrice 
Published: October 2013

Blood platelets play a key role in arterial thrombosis which is one of the leading causes of mortality in western countries. They may also be involved in the pathogenesis of deep vein thrombosis. Adenosine 5′‐diphosphate (ADP) is one of the most important mediators of platelet activation. Two G protein‐coupled ADP receptors, P2Y1 and P2Y12, selectively contribute to platelet aggregation and formation of a thrombus. Playing a central role in platelet activation and in growth and stabilization of a thrombus, the P2Y12 receptor is an established target of antithrombotic drugs like the thienopyridines clopidogrel or prasugrel, or direct reversible antagonists such as ticagrelor or cangrelor. Each of these drugs has proven efficacy in large clinical trials. At a preclinical stage, studies in P2Y1 deficient mice and using selective P2Y1 antagonists in experimental models of thrombosis and inflammation have shown that this receptor is also an attractive target for new antithrombotic compounds.

Published: October 2013

AbstractBackground
The nontechnical and team skills of surgical teams are critical for safety and efficiency in the operating room. Assessment of nontechnical and team skills can facilitate improvement by encouraging both self‐reflection and team reflection, identifying training needs, and informing operating room (OR) team training approaches. The observational teamwork assessment for surgery (OTAS) tool is a well‐validated and robust tool for capturing teamwork in the operating room. The aims of the present study were to systematically adapt and refine the OTAS for German‐speaking OR staff and to test the adapted assessment tool (OTAS‐D) for psychometric properties and metric equivalence.MethodsThe study was carried out in three stages: at stage 1, OTAS was translated into German. At stage 2, experienced German OR experts (surgeons, OR nurses, anesthetists) were interviewed. At stage 3, two blinded assessors observed 11 general surgical operations (general surgical and vascular procedures) and interrater reliability was tested for refined OTAS‐D behavioral exemplars and scorings.ResultsThe German OR experts confirmed the applicability and content validity of the vast majority of translated behavioral exemplars. After their evaluation, 32 items were changed slightly, six were changed substantially, and one item was added. During observations, perfect and substantial interobserver agreement was found for 77 behavioral exemplars (67.1 % of the items, kappa coefficient >0.60). Rating at all OTAS behaviors showed acceptable levels of reliability (intraclass correlation coefficients >0.72).ConclusionsThe OTAS‐D is a tool for valid and reliable assessment of nontechnical skills that contribute to safe and effective surgical performance in ORs staffed by German‐speaking professionals. Furthermore, our study serves as an example for systematically adapting and customizing well‐established observational tools across different healthcare environments.
