An experimental test of green management information system effects on carrier selection: weigh station and tollbooth bypass technology adoption

In a highly competitive price-driven industry, carriers are continuously searching for opportunities to differentiate their offerings, minimize operational costs, and appeal to shippers. At the same time, environmental sustainability has evolved from being trendy jargon into a requirement for competitive supply chain management. It is at the intersection of these two modern topics that the current study identifies a new carrier selection attribute based on a specialized type of green management information system. We apply social exchange theory to hypothesize carrier price and green technology adoption effects on shipper purchase intent. The hypothesized direct and interaction effects are tested by way of a vignette-based experiment, with a sample of full-time working professionals. The supported hypotheses collectively suggest that the adoption of weigh station and tollbooth bypass technology, as a type of environmentally sustainable information system, positively affects transportation carrier selection and attenuates the negative effect of a carrier’s price on shippers’ purchase intentions. These research findings offer unique theoretical, practical, and policy implications surrounding the trucking carrier selection decision

Adapting Clinical Services To Accommodate Needs of Refugee Populations

The diversity of the refugee population in the United States requires practicing psychologists to respond by adapting clinical services to meet their mental health needs. However, the available literature on culturally adapted treatments is only a first step in guiding the process for adapting clinical services. This paper describes our experiences with designing and adapting a variety of clinical services for youth and families with refugee status. Guided by Sue\u27s (2006) tenets for culturally competent service delivery, we discuss a therapeutic model of tiered service delivery used to deliver preventative services and treatment to refugee youth and adults. We discuss how we adapted treatments to help overcome access barriers to mental health treatment, and we provide specific examples of how existing treatments were used with refugee populations. In addition, we discuss information and approaches for how practicing psychologists can develop additional skills for working with refugee populations. We conclude by focusing on the need for our field to work toward improving access to mental health treatment for refugee youth and families and developing evidence-based treatments for this population

Selection and exploitation of prevalent, tandemly repeated genomic targets for improved real-time PCR-based detection of Wuchereria bancrofti and Plasmodium falciparum in mosquitoes

Optimization of polymerase chain reaction (PCR)-based diagnostics requires the careful selection of molecular targets that are both highly repetitive and pathogen-specific. Advances in both next-generation sequencing (NGS) technologies and bioinformaticsbased analysis tools are facilitating this selection process, informing target choices and reducing labor. Once developed, such assays provide disease control and elimination programs with an additional set of tools capable of evaluating and monitoring intervention successes. The importance of such tools is heightened as intervention efforts approach their endpoints, as accurate and complete information is an essential component of the informed decision-making process. As global efforts for the control and elimination of both lymphatic filariasis and malaria continue to make significant gains, the benefits of diagnostics with improved analytical and clinical/field-based sensitivities and specificities will become increasingly apparent

Why Wait?: Early Enteral Feeding After Pediatric Gastrostomy Tube Placement

Purpose Early initiation of feedings after gastrostomy tube (GT) placement may reduce associated hospital costs, but many surgeons fear complications could result from earlier feeds. We hypothesized that, irrespective of placement method, starting feedings within the first 6 h following GT placement would not result in a greater number of post-operative complications. Methods An IRB-approved retrospective review of all GTs placed between January 2012 and December 2014 at three academic institutions was undertaken. Data was stratified by placement method and whether the patient was initiated on feeds at less than 6 h or after. Baseline demographics, operative variables, post-operative management and complications were analyzed. Descriptive statistics were used and P-values < 0.05 were considered significant. Results One thousand and forty-eight patients met inclusion criteria. GTs were inserted endoscopically (48.9%), laparoscopically (44.9%), or via an open approach (6.2%). Demographics were similar in early and late fed groups. When controlling for method of placement, those patients who were fed within the first 6 h after gastrostomy placement had shorter lengths of stay compared to those fed greater than 6 h after placement (P < 0.05). Total post-operative outcomes were equivalent between feeding groups for all methods of placement (laparoscopic (P = 0.87), PEG (P = 0.94), open (P = 0.81)). Conclusions Early initiation of feedings following GT placement was not associated with an increase in complications. Feeds initiated earlier may shorten hospital stays and decrease overall hospital costs

Enhancing comfort of resident physicians treating adults with intellectual and developmental disabilities by facilitating meaningful interactions

BackgroundMany physicians feel uncomfortable caring for patients with intellectual and developmental disabilities (IDD). While some residency training programs include lecture content on IDD, few provide structured experiences with individuals with IDD. One strategy for improving comfort is “contact theory:” increasing interactions with “dissimilar” people can lead to decreased negative attitudes toward that population.ObjectiveEvaluate the impact of an interactive session on resident physicians’ comfort with adults with IDD.MethodsSmall groups of resident physicians and artists with IDD collaborated on art projects during the noon conference. A prospective pre-post-intervention survey, including the validated Interaction with Disabled Persons Scale (IDP), evaluated residents’ comfort with patients with IDD before and after the session.Results53 residents completed both pre- and post-conference surveys. Mean IDP scores decreased from 78.7 (10.9) to 75.8 (9.5; p &lt; 0.01), indicating decreasing discomfort. The mean level of comfort interacting with individuals with IDD increased from uncomfortable 3.6 (1.2), before the intervention, to comfortable 4.4 (1.2) after the intervention (p = &lt;0.01). The mean level of comfort treating individuals with IDD increased from uncomfortable 3.5 (1.1) to comfortable 4.1 (1.3) after the intervention (p &lt; 0.01).DiscussionProviding resident physicians with real-life connections with people with IDD was associated with increased comfort. If statistically significant improvements occurred after one session, future studies should evaluate if additional experiences with people with IDD could have more substantial, lasting impacts on future doctors’ comfort with and willingness to care for patients with IDD

Suppressing Aneuploidy-Associated Phenotypes Improves the Fitness of Trisomy 21 Cells

An abnormal number of chromosomes, or aneuploidy, accounts for most spontaneous abortions, causes developmental defects, and is associated with aging and cancer. The molecular mechanisms by which aneuploidy disrupts cellular function remain largely unknown. Here, we show that aneuploidy disrupts the morphology of the nucleus. Mutations that increase the levels of long-chain bases suppress nuclear abnormalities of aneuploid yeast independent of karyotype identity. Quantitative lipidomics indicates that long-chain bases are integral components of the nuclear membrane in yeast. Cells isolated from patients with Down syndrome also show that abnormal nuclear morphologies and increases in long-chain bases not only suppress these abnormalities but also improve their fitness. We obtained similar results with cells isolated from patients with Patau or Edward syndrome, indicating that increases in long-chain bases improve the fitness of aneuploid cells in yeast and humans. Targeting lipid biosynthesis pathways represents an important strategy to suppress nuclear abnormalities in aneuploidy-associated diseases

The Effect of Cone Opsin Mutations on Retinal Structure and the Integrity of the Photoreceptor Mosaic

Purpose. To evaluate retinal structure and photoreceptor mosaic integrity in subjects with OPN1LW and OPN1MW mutations. Methods. Eleven subjects were recruited, eight of whom have been previously described. Cone and rod density was measured using images of the photoreceptor mosaic obtained from an adaptive optics scanning light ophthalmoscope (AOSLO). Total retinal thickness, inner retinal thickness, and outer nuclear layer plus Henle fiber layer (ONL+HFL) thickness were measured using cross-sectional spectral-domain optical coherence tomography (SD-OCT) images. Molecular genetic analyses were performed to characterize the OPN1LW/OPN1MW gene array. Results. While disruptions in retinal lamination and cone mosaic structure were observed in all subjects, genotype-specific differences were also observed. For example, subjects with “L/M interchange” mutations resulting from intermixing of ancestral OPN1LW and OPN1MW genes had significant residual cone structure in the parafovea (∼25% of normal), despite widespread retinal disruption that included a large foveal lesion and thinning of the parafoveal inner retina. These subjects also reported a later-onset, progressive loss of visual function. In contrast, subjects with the C203R missense mutation presented with congenital blue cone monochromacy, with retinal lamination defects being restricted to the ONL+HFL and the degree of residual cone structure (8% of normal) being consistent with that expected for the S-cone submosaic. Conclusions. The photoreceptor phenotype associated with OPN1LW and OPN1MW mutations is highly variable. These findings have implications for the potential restoration of visual function in subjects with opsin mutations. Our study highlights the importance of high-resolution phenotyping to characterize cellular structure in inherited retinal disease; such information will be critical for selecting patients most likely to respond to therapeutic intervention and for establishing a baseline for evaluating treatment efficacy

Integration of Nodal and BMP Signals in the Heart Requires FoxH1 to Create Left–Right Differences in Cell Migration Rates That Direct Cardiac Asymmetry

Failure to properly establish the left–right (L/R) axis is a major cause of congenital heart defects in humans, but how L/R patterning of the embryo leads to asymmetric cardiac morphogenesis is still unclear. We find that asymmetric Nodal signaling on the left and Bmp signaling act in parallel to establish zebrafish cardiac laterality by modulating cell migration velocities across the L/R axis. Moreover, we demonstrate that Nodal plays the crucial role in generating asymmetry in the heart and that Bmp signaling via Bmp4 is dispensable in the presence of asymmetric Nodal signaling. In addition, we identify a previously unappreciated role for the Nodal-transcription factor FoxH1 in mediating cell responsiveness to Bmp, further linking the control of these two pathways in the heart. The interplay between these TGFβ pathways is complex, with Nodal signaling potentially acting to limit the response to Bmp pathway activation and the dosage of Bmp signals being critical to limit migration rates. These findings have implications for understanding the complex genetic interactions that lead to congenital heart disease in humans
