Religious orientation, low self‐control, and deviance: Muslims, Catholics, Eastern Orthodox‐, and “Bible Belt” Christians⋆
Authors: Klanjšek Rudi , Vazsonyi Alexander T. , Trejos‐Castillo Elizabeth 
Published: October 2011

ABSTRACTUsing adolescent samples from four cultures, the current study tested whether effects by religiosity on deviance varied by the nature of religiosity (intrinsic versus extrinsic) and by the cultural context (Bosnia & Herzegovina, Serbia, Slovenia, and the U.S.). Results indicated: a) that not every type of religiosity has a buffering effect on deviance – if one’s religiousness is predominately instrumental (i.e. extrinsic), then its inhibiting effect is weak or does not exist; b) that the effect of intrinsic religiosity seemed more pronounced in the two surroundings that expressed the highest mean religiosity (U.S., Bosnia & Herzegovina) although results from follow‐up analysis (Z‐tests) largely supported a cultural invariance hypothesis. In addition, the intrinsic religiosity–deviance link was moderated by low self‐control in each sample, except the Slovenian one. Finally, results indicated that low self‐control only partially mediated the religiosity–deviance link.
Interpersonal identity formation in conversations with close friends about dating relationships
Authors: Morgan Elizabeth M. , Korobov Neill 
Published: October 2011

ABSTRACTThe present study explores how close same‐sex friendship groups participate in the co‐construction of identities in the interpersonal domain during young adulthood. Participants included 24 same‐sex college student friendship triads (12 male and 12 female; 72 total participants) who took part in semi‐structured group interviews that elicited stories about conversations with their friends about dating relationship problems. Qualitative thematic analysis revealed five common responses to dating problems evidencing identity work in the context of friends’ conversations. These responses included relating the issue to one’s own experiences, providing validation and encouragement, joking about the problem, offering advice, and providing concrete instrumental support. Results are interpreted with regard to gender differences and similarities as well as the social context of college and developmental context of emerging adulthood. The findings identify ways in which young adults are actively co‐constructing and re‐evaluating their interpersonal identities within conversations with close same‐sex friends.

Published: October 2011

Background While the mean injury rate from snow sports in Austria is low (less than 2 injuries per 1000 skier days), there is little information about fatalities on Austrian ski slopes. Objective The purpose of this study was to evaluate incidence and causes of fatalities among recreational skiers and snowboarders over a 5-season period on Austrian ski slopes. Methods All traumatic and nontraumatic fatal ski accidents from the 2005-2006 through the 2009-2010 winter season were compiled by members of the Federal Ministry of the Interior. Data on age, gender, nationality, gear used, altitude, accident cause, primary cause of death, and helmet use were collected. The number of fatalities was related to a million skier days during this 5-year period. Results In total, 207 fatalities were registered during this time period. An overall incidence of 0.79 deaths per million skier days was calculated. Mean age was 50.9 ± 17.7 years. More than 85% of all fatalities occurred in males and 93.1% in skiers. Mean altitude was 1706.1 ± 517.7 m above sea level. In total, 52.7% were nontraumatic deaths, with the majority (73%) attributed to cardiac arrest. Regarding traumatic deaths, 41.2% died after a fall, 18.6% after collision with another skier, and 35.1% after an impact with a solid object. Head injury was the primary cause of death in 46.4% of traumatic deaths. Conclusions Death is a rare event in recreational winter sports on Austrian ski slopes. Nevertheless, awareness of potential risk factors and common dangers may impact snow riders' behavior and help reduce the incidence of on-slope fatalities.

Published: October 2011

Objective Hemodynamic changes in response to the hypoxic environment of high altitude are vascular bed-specific. The aim of the present study was to investigate diameter and blood flow changes in conduit vessels in response to hypobaric hypoxia. Methods Eleven healthy subjects ascending Mount Everest to base camp participated in this study. Vessel diameter and blood velocity for brachial, carotid, common femoral, superficial femoral, and deep femoral arteries were measured by portable Doppler ultrasound. Blood flow was calculated from these values. Measurements were taken at sea level, at increasing altitudes on ascent to base camp (1310 m, 3470 m, 5330 m), and repeated on descent to lower altitude (1310 m). Results For all vessels except carotids, both vessel diameter and blood flow decreased between sea level and initial ascent to altitude, with subsequent persistence of these decreased values; there was no further significant change with continued ascent to higher altitude. Blood flow for all arteries (except carotids) increased significantly on descent to lower altitude, with an associated nonsignificant increase in velocity and decrease in diameter. Conclusions This study showed that there is vasoconstriction of limb conduit vessels at altitude, which persists upon descent to lower altitude. Blood flow in these vessels also decreases with initial exposure to high altitude, yet increases when returning to lower altitude, reflecting variations in blood velocity. Carotid arteries responded differently to the stimulus of hypobaria than limb conduit vessels; there was no change in diameter seen on ascent or descent, but there was a progressive decrease in blood flow on ascent, with no change on subsequent descent.
Sequential Monte Carlo multiple testing
Authors: Sandve Geir Kjetil , Ferkingstad Egil , Nygård Ståle 
Published: October 2011

Abstract
Motivation: In molecular biology, as in many other scientific fields, the scale of analyses is ever increasing. Often, complex Monte Carlo simulation is required, sometimes within a large-scale multiple testing setting. The resulting computational costs may be prohibitively high.
Results: We here present MCFDR, a simple, novel algorithm for false discovery rate (FDR) modulated sequential Monte Carlo (MC) multiple hypothesis testing. The algorithm iterates between adding MC samples across tests and calculating intermediate FDR values for the collection of tests. MC sampling is stopped either by sequential MC or based on a threshold on FDR. An essential property of the algorithm is that it limits the total number of MC samples whatever the number of true null hypotheses. We show on both real and simulated data that the proposed algorithm provides large gains in computational efficiency.
Availability: MCFDR is implemented in the Genomic HyperBrowser (http://hyperbrowser.uio.no/mcfdr), a web-based system for genome analysis. All input data and results are available and can be reproduced through a Galaxy Pages document at: http://hyperbrowser.uio.no/mcfdr/u/sandve/p/mcfdr.

LPS‐binding Protein Enables Intestinal Epithelial Restitution Despite LPS Exposure
Authors: Richter Juli M. , Schanbacher Brandon L. , Huang Hong , Xue Jianjing , Bauer John A. , Giannone Peter J. 
Published: October 2011

ABSTRACTObjectives:Intestinal epithelial restitution is the first part in the process of mucosal repair after injury in the intestine. Integrity of the intestinal mucosal barrier is important as a first line of defense against bacteria and endotoxin. Necrotizing enterocolitis (NEC) is a major cause of morbidity and mortality in extremely‐low‐birth‐weight infants, but its mechanisms are not well defined. Abnormal bacterial colonization, immature barrier function, innate immunity activation, and inflammation likely play a role. Lipopolysaccharide (LPS)‐binding protein (LBP) is secreted by enterocytes in response to inflammatory stimuli and has concentration‐dependent effects. At basal concentrations, LBP stimulates the inflammatory response by presenting LPS to its receptor; however, at high concentrations, LBP is able to neutralize LPS and prevent an exaggerated inflammatory response. We sought to determine how LBP would affect wound healing in an in vitro model of intestinal cell restitution and protect against intestinal injury in a rodent model of NEC.Methods:Immature intestinal epithelial cells (IEC‐6) were seeded in poly‐L‐lysine–coated 8‐chamber slides and grown to confluence. A 500‐μm wound was created using a cell scraper mounted on the microscope to achieve uniform wounding. Media was replaced with media containing LPS ± LBP. Slide wells were imaged after 0, 8, and 24 hours and then fixed. Cellular restitution was evaluated via digital images captured on an inverted microscope and wound closure was determined by automated analysis. Toll‐like receptor 4 (TLR4) was determined by reverse transcriptase‐polymerase chain reaction after RNA isolation from wounded cells 24 hours after treatment.Results:LPS alone attenuated wound healing in immature intestinal epithelium. This attenuation is reversed by 24 hours with increasing concentrations of LBP so that wound healing is equivalent to control (P < 0.001). TLR4 was increased with LPS alone but levels returned to that of control after addition of LBP in the higher concentrations. LBP had no effect on the development of intestinal injury when given during our rodent model of NEC. Abnormal bacterial colonization and activation of innate immunity by LPS are likely involved in the pathogenesis of NEC.The attenuation of wound healing was reversed when LBP was added to LPS but only in the higher concentrations. At these same concentrations of LBP, TLR4 was decreased to that of control.Conclusions:These results indicate that LBP may be a novel therapeutic strategy to facilitate wound healing after the acute phase of NEC and other forms of intestinal injury.

ABSTRACTObjectives:Little is known about risk factors for biliary pancreatitis in children. We characterized cases of pediatric biliary pancreatitis, compared biliary with nonbiliary cases, examined differences in presentation between younger and older children, and studied features distinguishing gallstone‐ from sludge‐induced pancreatitis.Methods:We evaluated 76 episodes of biliary pancreatitis from 271 cases of acute pancreatitis in children admitted to a tertiary care hospital from 1994 to 2007.Results:Of the 76 cases, 55% had gallstones, 21% had sludge, and 24% had structural defects. Hispanic children had 2.85 (P = 0.01) and 5.59 (P = 0.003) times higher probability for biliary pancreatitis than white and black children, respectively. Median serum amylase and lipase in children with biliary pancreatitis were 64% and 49% higher, respectively, compared with other causes (P < 0.05). In multiple logistic regression, aspartate aminotransferase was an independent predictor of biliary pancreatitis (odds ratio 6.69, P = 0.001). When comparing gallstone‐ with sludge‐induced causes, obesity was an independent predictor (38% more prevalent, P < 0.01) of gallstone cases.Conclusions:Hispanic ethnicity is a risk factor and aspartate aminotransferase is a biomarker for biliary pancreatitis over other causes. Furthermore, obesity can distinguish gallstone‐ from sludge‐induced pancreatitis. These findings may spur prospective studies to determine the optimal evaluation and management of children with biliary pancreatitis.
Scholarly impact measurements of LIS open access journals: based on citations and links
Authors: Yuan Shunbo , Hua Weina 
Published: October 2011

PurposeThe main purpose of this paper is to measure the scholarly impact of LIS (Library and Information Science) open access journals (OA journals), most of which are not indexed by the Web of Science (WoS). In addition, the paper seeks to discuss measurement methods beyond citation analysis.Design/methodology/approachThe study selected 97 LIS OA journals as a sample and measured their scholarly impact on the basis of citations and links. The citation counts in WoS, coverage in LISA, Web links, WIFs and Page Rank of the journals are retrieved and calculated, and correlations between citation counts, links, pages, WIFs, and Page Rank are also analyzed.FindingsThe results indicate that LIS OA journals have become a significant component of the scholarly communication system. TheJournal of the Medical Library Associationenjoys the highest citation counts in WoS. This journal, together withD‐Lib Magazine,Information Research,Ariadne, Cybermetrics, andFirst Mondayare the six most important LIS OA journals. With regard to coverage in LISA,Bulletin des Bibliothèques de France(2151) performs best. As a whole, the Page Rank is relatively high, mostly at 6, 7, or 8. The study finds that correlation between citation‐based measurements and link‐based measurements tends to be significant.Originality/valueThis paper uses the web as a global resource to measure the impact of LIS OA journals by analyzing citation, coverage, web links and Page Rank. The focus of this study is the value of the web as a source of impact indices, rather different from the traditional research methods. It contributes to the scholarly impact measurements of OA journals.
Determinants of digitally instigated insurance relationships
Authors: Gidhagen Mikael , Gebert Persson Sabine 
Published: October 2011

PurposeThe purpose of this paper is to develop a conceptual model for explaining insurance customers' intentions towards using the internet as a channel for communication and interaction with insurance companies by integrating Technology Acceptance Model (TAM) and trust.Design/methodology/approachThe paper seeks to conceptually develop an integrated framework for studying and measuring the perceptions of customers towards using the internet as a source of communication and interaction. The TAM model is taken as a point of departure where trust and trustworthiness, being essential in insurance relationships, have been included in the model. Trust is divided into perceived competence, perceived benevolence and perceived integrity, which in turn affect whether the customer will find the firm trustworthy or not. A second dimension that is developed in this paper is the disposition to trust, which is defined as a customer‐related factor. This disposition to trust is in turn affected by the customer's internet knowledge and product knowledge.FindingsThe paper contributes by developing the model for understanding and explaining factors that affect customers' attitudes and intentions towards on‐line interactions. By emphasizing internet‐, customer‐ and Ffrm‐related factors, it would arguably be possible to explain factors that affect trust, and trustworthiness, as well as the customer's attitudes towards the organization and the communication and distribution channel while also integrating the customer‐specific factors.Research limitationsThe model developed in this paper is conceptual and needs to be tested empirically.Originality/valueThe findings of this paper will serve as a basis for further research aiming at answering the research question on what factors affect customers' attitudes towards using the internet as an interface within the financial services sector. It also contributes to practices by identifying and defining factors that can affect trust in relationships as well as the choice of communication and distribution channels depending on customers' attitudes.
University librarians respond to changes in higher education: example of a medical school
Authors: Chang Sung‐Shan , Chen Kuan‐nien 
Published: October 2011

PurposeThe purpose of this paper is to discuss three recent changes in higher education – the addition of technology to every aspect of the curriculum, the increase in the availability of electronic resources, and the introduction of constructivist pedagogy. In light of these changes, the authors aim to explore what university libraries and librarians should reinforce in terms of their concepts and competency and adjust the ways that they serve students.Design/methodology/approachThe authors analyze the related literature and identified technology, electronic resources, and constructivist pedagogy that interact with the new curriculum of universities in a broader way than in the past.FindingsThe three dimensions, separately and in combination, require considerable adjustments by librarians, teachers, students, and the school/university community in general. Collaboration among all members of staff, particularly between librarians and teachers, is essential. The emerging paradigm, still firmly based in constructivist principles, recognizes that there is a need for staff guidance of students though they are expected to become increasingly independent as they progress through the system. Meanwhile, two new core competencies have emerged for university librarians: information literacy and problem‐based learning (PBL).Originality/valueThe emergence of the two competencies has reminded librarians to learn, change and grow constantly to serve PBL students effectively.
Is social software really a “killer app” in the education of net generation students? Findings from a case study
Authors: Feuer Gabor 
Published: October 2011

PurposeSocial software is increasingly viewed as the new “killer application” in higher education – a potential answer to needs ranging from active learning and student engagement, to faculty empowerment. The purpose of this study is to explore this potential in the context of participating net generation students in a science and technology oriented, laptop‐based university located in Southern Ontario. The study is interested in the efficacy and pedagogical impact of social software (SSW) technologies in the students' learning experience.Design/methodology/approachThe research model used an exploratory, descriptive, quantitative case study. The focus of the study was on the impacts of SSW on students' information literacy skills. A quasi‐experimental model was used to compare the effects of SSW use in information literacy instruction with those of traditional educational technologies such as learning management systems (LMS).FindingsA total of 80 students participated. Twenty‐four students in the treatment group used SSW during the instruction phase, while in the control group, 56 used the LMS. The pre‐test showed a relatively moderate use of SSW technologies among the participants, with the exception of social networking technologies. At the completion of the study, students showed moderate willingness to employ SSW to enhance their learning. Barriers to the adoption of these technologies were highlighted. The study findings could not demonstrate that the use of SSW, compared with more established technologies such as the LMS would lead to different information literacy scores.Originality/valueThis is a summary of my original PhD research completed in 2009. A shorter poster version was presented at the 2011 IATUL Conference in June 2011 at Warsaw, Poland.
The impact of relationship quality on attitude toward a sponsor
Authors: Kyoum Kim Yu , Jae Ko Yong , James Jeffery 
Published: October 2011

PurposeThe purpose of the current study is to advance understanding of sponsorship effectiveness by investigating the impact of the quality of the relationship between a consumer and a sport property on sponsorship effectiveness.Design/methodology/approachA model was developed to examine linkages among relationship quality, sincerity, attitude toward sponsor and intention to purchase a sponsor's product. The measurement model was tested using confirmatory factory analysis. The relationships in the hypothesized model were tested using simultaneous equations.FindingsThe results indicate that positive attitude toward a sponsor and intention to purchase said sponsor's product(s) are more likely to occur among the customers who perceive a higher degree of relationship quality with the sport property and believe the sponsor motives are sincere.Research limitations/implicationsA conceptual model of sponsorship effectiveness was developed and empirically tested. The tested model provides an expanded view of relationship quality and its impact on key variables of sponsorship effectiveness.Practical implicationsProvided in this study is a framework for both sponsors and sport teams that can be used to understand some of the ways in which sponsorship works. The findings suggest that sponsors should leverage their activities to communicate sincere motives, not just “doing business”. For the sport property, the implication is developing quality relationships with consumers, and being able to promote such relationships to prospective sponsors.Originality/valueRelationship quality has been previously shown to influence various behavioral aspects related to partners in business‐to‐business relationships. This study extends the literature by examining the effect of business‐to‐consumer relationship quality on the expected outcomes associated with a business‐to‐business relationship.
