    Description: To link to full-text access for this article, visit this link: http://dx.doi.org/10.1016/j.indmarman.2013.05.013 Byline: Talai Osmonbekov, Thomas Gruen Abstract: Manufacturer-reseller e-business arrangements are changing the nature of channel relationships. When manufacturers supply e-business tools to their resellers, resellers may perceive that the benefits of technology are not shared equitably. This research explores this issue by examining two technology based antecedents of perceived inequity from the reseller perspective. We also examine the impact of perceived inequity on relationship performance, and the moderating role of reseller dependence on the proposed inequity-performance link. The results of the empirical test involving a sample of 224 resellers suggest that perceived inequity negatively impacts relationship performance, while reseller dependence plays a moderating role. Implications of these findings for researchers and managers are discussed. Article History: Received 1 September 2012; Revised 28 March 2013; Accepted 23 April 2013

    Description: The dilemma that clinicians involved in the resuscitation of severely injured patients face with regards to the inclusion of tranexamic acid (TxA) in trauma management protocols is discussed. However, on the other hand, the need for more evidence to solve ongoing knowledge gaps has been emphasised, especially evidence of who benefits and whether anyone is harmed when TxA is administered to patients treated to modern civilian and military trauma standards.

    Description: Survey research remains the most popular source of market knowledge, yet researchers have not yet established one consistent technique for measuring responses. Some market research companies offer respondents two answer options; others five or seven. Some answer formats use middle points on the answer scales, others do not. Some formats verbalize all answer options, some only the endpoints. The wide variety of answer formats that market research companies and academic researchers use makes comparing results across studies virtually impossible. This study offers guidance for market researchers by presenting empirical translations for the answer formats they most commonly use, thus enabling easier comparisons of results.

    Description: Stem–cement and cement–bone interfacial failures as well as cement fractures have been noted in cemented total hip arthroplasty (THA) as the cause of aseptic loosening. Attempts to reduce the risk of femoral component loosening include improving the stem–cement interface by various coatings, using a textured or porous coated stem surfaces or by using a tapered stem having a highly-polished surface. The latter approach, often referred to as “force-closed” femoral stem design, would theoretically result in stem stabilization subsequent to debonding and ‘taper-lock’. Previous work using three-dimensional finite element analysis has shown a state of stress at the stem–cement interface indicative of ‘taper-lock’ for the debonded stem and indicated that stem–cement interface friction and bone cement creep played a significant role in the magnitudes of stresses and subsidence of the stem. However, the previous analysis did not include the viscoelastic properties of bone, which has been hypothesized to permit additional expansion of the bone canal and allow additional stem subsidence ( ). The goal of this study was to investigate the effect of bone viscoelastic behavior on stem subsidence using a 3D finite element analysis. It was hypothesized that the viscoelastic behavior of bone in the hoop direction would allow expansion of the bone reducing the constraint on bone over time and permit additional stem subsidence, which may account for the discrepancies between predicted and clinical subsidence measurements. Analyses were conducted using physiological loads, ‘average peak loads’ and ‘high peak loads’ for ‘normal patient’ and ‘active patient’ ( ) from which short and long term subsidence was predicted. Results indicated that bone creep does contribute to higher stem subsidence initially and after 10 years of simulated loading. However, it was concluded that the “constraint” upon the cement mantle is not mitigated enough to result in stem subsidence equivalent to that observed clinically.

    Description: To investigate whether prenatal exposure to nicotine has an impact on several reading skill outcomes in school age children. Using a longitudinal sample of 5119 school age children in the Avon Longitudinal Study of Parents and Children, this study investigated specific reading skill outcomes in the area of speed, fluency, accuracy, spelling, and comprehension in relation to prenatal nicotine exposure, after adjusting for potential mediators and confounders. Prenatal nicotine exposure was divided into 3 categories: high (〉17 mg per day), low (≤17 mg per day), and no exposure. We found that prenatal nicotine exposure was associated with increased risk of underperformance in specific reading skill outcomes after adjusting for potential mediators and confounders ( = .006). The effect of poor performance in decoding single words was most pronounced among children with prenatal exposure to high levels of nicotine in conjunction with a phonological deficit. Overall, the results showed that maternal smoking has moderate to large associations with delayed or decreased reading skills of children in the Longitudinal Study of Parents and Children. High prenatal nicotine exposure has a negative association with reading performance in school age children. In addition, modeling showed that environmental factors significantly moderated the interaction between prenatal nicotine exposure and reading skill outcomes.

    Description: Through whole-genome sequencing of 2,230 Icelanders, we detected a rare nonsynonymous SNP (minor allele frequency = 0.55%) in the C3 gene encoding a p.Lys155Gln substitution in complement factor 3, which, following imputation into a set of Icelandic cases with age-related macular degeneration (AMD) and controls, associated with disease (odds ratio (OR) = 3.45; P = 1.1 x [10.sup.-7]). This signal is independent of the previously reported common SNPs in C3 encoding p.Pro314Leu and p.Arg102Gly that associate with AMD. The association of p.Lys155Gln was replicated in AMD case-control samples of European ancestry with OR = 4.22 and P = 1.6 x 1[0.sup.-10], resulting in OR = 3.65 and P = 8.8 x [10.sup.-16] for all studies combined. In vitro studies have suggested that the p.Lys155Gln substitution reduces C3b binding to complement factor H, potentially creating resistance to inhibition by this factor. This resistance to inhibition in turn is predicted to result in enhanced complement activation.

    Description: We present a multistep process for identifying priority research areas in rehabilitation and long-term care of traumatic brain-injured (TBI) patients. In particular, we aimed to (1) identify which stakeholders should be involved; (2) identify what methods are appropriate; (3) examine different criteria for the generation of research priority areas; and (4) test the feasibility of linkage and exchange among researchers, decision makers, and other potential users of the research. Potential research questions were identified and developed using an initial scoping meeting and preliminary literature search, followed by a facilitated mapping workshop and an online survey. Identified research questions were then prioritized against specific criteria (clinical importance, novelty, and controversy). Existing evidence was then mapped to the high-priority questions using usual processes for search, screening, and selection. A broad range of stakeholders were then brought together at a forum to identify priority research themes for future research investment. Using clinical and research leaders, smaller targeted planning workshops prioritized specific research projects for each of the identified themes. Twenty-six specific questions about TBI rehabilitation were generated, 14 of which were high priority. No one method identified all high-priority questions. Methods that relied solely on the views of clinicians and researchers identified fewer high-priority questions compared with methods that used broader stakeholder engagement. Evidence maps of these high-priority questions yielded a number of evidence gaps. Priority questions and evidence maps were then used to inform a research forum, which identified 12 priority themes for future research. Our research demonstrates the value of a multistep and multimethod process involving many different types of stakeholders for prioritizing research to improve the rehabilitation outcomes of people who have suffered TBI. Enhancing stakeholder representation can be augmented using a combination of methods and a process of linkage and exchange. This process can inform decisions about prioritization of research areas.
