Due to the variations of design and protocol in qualitative inquiry, researchers may inadvertently create problems for themselves in terms of the trustworthiness of their research. Miscommunication between participants and researchers can especially arise from the unique and unpredictable nature of human dynamics. In this paper I contend that such problems, or traps, can easily and at times unknowingly be set during the qualitative process known as member checking, threatening the researcher/participant relationship and possibly the stability of the study. In this paper, I examine member checking through five vignettes personally experienced. These vignettes are preceded by a presentation of common procedures for increasing trustworthiness, and are followed by several recommendations for avoiding the setting and triggering of member checking traps.

Ticks transmit more pathogens to humans and animals than any other arthropod. We describe the 2.1 Gbp nuclear genome of the tick, Ixodes scapularis (Say), which vectors pathogens that cause Lyme disease, human granulocytic anaplasmosis, babesiosis and other diseases. The large genome reflects accumulation of repetitive DNA, new lineages of retro-transposons, and gene architecture patterns resembling ancient metazoans rather than pancrustaceans. Annotation of scaffolds representing ∼57% of the genome, reveals 20,486 protein-coding genes and expansions of gene families associated with tick-host interactions. We report insights from genome analyses into parasitic processes unique to ticks, including host 'questing', prolonged feeding, cuticle synthesis, blood meal concentration, novel methods of haemoglobin digestion, haem detoxification, vitellogenesis and prolonged off-host survival. We identify proteins associated with the agent of human granulocytic anaplasmosis, an emerging disease, and the encephalitis-causing Langat virus, and a population structure correlated to life-history traits and transmission of the Lyme disease agent.

ABSTRACT The aggregate volume of equity issues is used to search for periods when seasoned equity capital can be raised at favorable terms. We find that the price reaction to equity issue announcements in high equity issue volume (HOT) periods is approximately 200 basis points lower on average than in low equity issue volume (COLD) periods. The lower price reaction in hot markets is economically important and is independent of the macroeconomic characteristics of hot and cold markets. The evidence supports the existence of windows of opportunity for equity issues that result at least partially from reduced levels of asymmetric information.

This paper uses a microlevel data set from 49 countries to create a direct measure of corruption, which portrays the extent of bribery as revealed by individuals who live in those countries. In addition, it investigates the determinants of being asked for a bribe at the individual level. The results show that both personal and country characteristics determine the risk of exposure to bribery. Examples are gender, income, education, marital status, the city size, the country’s unemployment rate, average education, and the strength of the institutions in the country. ( JEL K4, D73 P16)

Abstract We evaluated possible changes to current farming practices in two Minnesota watersheds to provide insight into how farm policy might affect environmental, social, and economic outcomes. Watershed residents helped develop four scenarios to evaluate alternative future trends in agricultural management and to project potential economic and environmental outcomes. We found that environmental and economic benefits can be attained through changes in agricultural land management without increasing public costs. The magnitude of these benefits depends on the magnitude of changes to agricultural practices. Environmental benefits include improved water quality, healthier fish, increased carbon sequestration, and decreased greenhouse gas emissions, while economic benefits include social capital formation, greater farm profitability, and avoided costs. Policy transitions that emphasize functions of agriculture in addition to food production are crucial for creating change. We suggest that redirecting farm payments by using alternative incentives could lead to substantial environmental changes at little or no extra cost to the taxpayer.

BACKGROUND AND OBJECTIVES: Inpatient pediatric mental health is a priority topic for national quality measurement and improvement, but nationally representative data on the patients admitted or their diagnoses are lacking. Our objectives were: to describe pediatric mental health hospitalizations at general medical facilities admitting children nationally; to assess which pediatric mental health diagnoses are frequent and costly at these hospitals; and to examine whether the most frequent diagnoses are similar to those at free-standing children's hospitals. METHODS: We examined all discharges in 2009 for patients aged 3 to 20 years in the nationally representative Kids' Inpatient Database (KID) and in the Pediatric Health Information System (free-standing children's hospitals). Main outcomes were frequency of International Classification of Diseases, Ninth Revision, Clinical Modification-defined mental health diagnostic groupings (primary and nonprimary diagnosis) and, using KID, resource utilization (defined by diagnostic grouping aggregate annual charges). RESULTS: Nearly 10% of pediatric hospitalizations nationally were for a primary mental health diagnosis, compared with 3% of hospitalizations at free-standing children's hospitals. Predictors of hospitalizations for a primary mental health problem were older age, male gender, white race, and insurance type. Nationally, the most frequent and costly primary mental health diagnoses were depression (44.1% of all mental health admissions; $1.33 billion), bipolar disorder (18.1%; $702 million), and psychosis (12.1%; $540 million). CONCLUSIONS: We identified the child mental health inpatient diagnoses with the highest frequency and highest costs as depression, bipolar disorder, and psychosis, with substance abuse an important comorbid diagnosis. These diagnoses can be used as priority conditions for pediatric mental health inpatient quality measurement.

BACKGROUND: An in-depth understanding of the fundamental principles that regulate thyroid hormone homeostasis is critical for the development of new diagnostic and treatment approaches for patients with thyroid disease. SUMMARY: Important clinical practices in use today for the treatment of patients with hypothyroidism, hyperthyroidism, or thyroid cancer are the result of laboratory discoveries made by scientists investigating the most basic aspects of thyroid structure and molecular biology. In this document, a panel of experts commissioned by the American Thyroid Association makes a series of recommendations related to the study of thyroid hormone economy and action. These recommendations are intended to promote standardization of study design, which should in turn increase the comparability and reproducibility of experimental findings. CONCLUSIONS: It is expected that adherence to these recommendations by investigators in the field will facilitate progress towards a better understanding of the thyroid gland and thyroid hormone dependent processes.

BACKGROUND: The objective of this study was to assess whether the use of staple line reinforcement (SLR) reduces staple line complications (SLC). Mechanical staple lines are essential for gastrointestinal surgery such as bariatric surgery. However, SLC, such as bleeding and leakage, still occur. The purposes of this study were to provide quantitative evidence on the relative efficacy of gastric SLR and to compare the rates of effectiveness of three commonly used methods. METHODS: A search of the medical literature in English language journals identified studies from Jan 1, 2000, to Dec 31, 2013, using the following reinforcement types: (1) no reinforcement, (2) oversewing, (3) a biocompatible glycolide copolymer, and (4) bovine pericardium after gastric bypasses and sleeve gastrectomies. Types of reinforcement were compared using a random-effects model. RESULTS: This meta-analysis reviewed 16,967 articles, extracting data on 56,309 patients concerning leak and 41,864 patients concerning bleeding. Over 40 % of patients had no reinforcement, resulting in the highest leak rate (2.75 %) and bleed rate (3.45 %). Overall, reinforcing with bovine pericardium had the lowest leak (1.28 %) and bleed (1.23 %) rates. Suture oversewing was better than no reinforcement but not as effective as bovine pericardium for leak (2.45 %) and bleed (2.69 %) rates. Buttressing with a biocompatible glycolide copolymer resulted in the second highest leak rate (2.61 %) and a bleed rate of 2.48 % but had significantly lower bleed rates than no reinforcement. CONCLUSIONS: SLR provided superior results for patients compared to no reinforcement for reducing SLC. Buttressing with bovine pericardium resulted in the most favorable outcomes. The effectiveness of different methods used to reinforce the staple line in gastric surgery does not appear to be equal.

The objectives of this research were to evaluate the efficacy of computer-delivered personalized normative feedback among heavy drinking college students and to evaluate controlled orientation as a moderator of intervention efficacy. Participants (N = 217) included primarily freshman and sophomore, heavy drinking students who were randomly assigned to receive or not to receive personalized normative feedback immediately following baseline assessment. Perceived norms, number of drinks per week, and alcohol-related problems were the main outcome measures. Controlled orientation was specified as a moderator. At 2-month follow-up, students who received normative feedback reported drinking fewer drinks per week than did students who did not receive feedback, and this reduction was mediated by changes in perceived norms. The intervention also reduced alcohol-related negative consequences among students who were higher in controlled orientation. These results provide further support for computer-delivered personalized normative feedback as an empirically supported brief intervention for heavy drinking college students, and they enhance the understanding of why and for whom normative feedback is effective.

BACKGROUND: National Guard troops are at increased risk for post-traumatic stress disorder (PTSD); however, little is known about risk and resilience in this population. METHOD: The Readiness and Resilience in National Guard Soldiers Study is a prospective, longitudinal investigation of 522 Army National Guard troops deployed to Iraq from March 2006 to July 2007. Participants completed measures of PTSD symptoms and potential risk/protective factors 1 month before deployment. Of these, 81% (n=424) completed measures of PTSD, deployment stressor exposure and post-deployment outcomes 2-3 months after returning from Iraq. New onset of probable PTSD 'diagnosis' was measured by the PTSD Checklist - Military (PCL-M). Independent predictors of new-onset probable PTSD were identified using hierarchical logistic regression analyses. RESULTS: At baseline prior to deployment, 3.7% had probable PTSD. Among soldiers without PTSD symptoms at baseline, 13.8% reported post-deployment new-onset probable PTSD. Hierarchical logistic regression adjusted for gender, age, race/ethnicity and military rank showed that reporting more stressors prior to deployment predicted new-onset probable PTSD [odds ratio (OR) 2.20] as did feeling less prepared for deployment (OR 0.58). After accounting for pre-deployment factors, new-onset probable PTSD was predicted by exposure to combat (OR 2.19) and to combat's aftermath (OR 1.62). Reporting more stressful life events after deployment (OR 1.96) was associated with increased odds of new-onset probable PTSD, while post-deployment social support (OR 0.31) was a significant protective factor in the etiology of PTSD. CONCLUSIONS: Combat exposure may be unavoidable in military service members, but other vulnerability and protective factors also predict PTSD and could be targets for prevention strategies.

Trait negative affectivity (NA) has been asserted to be a factor that spuriously inflates relationships between self-reported stressors and self-reported strain outcomes. We tested this hypothesis with conventional work stress instrument responses and physiological assessments obtained from 311 fire and police department employees. Confirmatory factor analyses indicated that NA did not measure a factor in common with measures of subjective strain. Latent-variable structural equations analyses, however, found that estimating the effects of NA on strain significantly attenuated the effects of work stressors. NA had no correlation with physiological stress outcomes. Trait positive affectivity did not attenuate relationships between work stressors and either subjective or objective stress outcomes. Implications for work stress research methodology and recommendations are discussed.

There is no widely accepted standard for antifungal prophylaxis in patients with hematologic malignancies. The Infectious Diseases Working Party of the German Society for Haematology and Oncology assigned a committee of hematologists and infectious disease specialists to develop recommendations. Literature data bases were systematically searched for clinical trials on antifungal prophylaxis. The studies identified were shared within the committee. Data were extracted by two of the authors (OAC and MSi). The consensus process was conducted by email communication. Finally, a review committee discussed the proposed recommendations. After consensus was established the recommendations were finalized. A total of 86 trials were identified including 16,922 patients. Only a few trials yielded significant differences in efficacy. Fluconazole 400 mg/d improved the incidence rates of invasive fungal infections and attributable mortality in allogeneic stem cell recipients. Posaconazole 600 mg/d reduced the incidence of IFI and attributable mortality in allogeneic stem cell recipients with severe graft versus host disease, and in patients with acute myelogenous leukemia or myelodysplastic syndrome additionally reduced overall mortality. Aerosolized liposomal amphotericin B reduced the incidence rate of invasive pulmonary aspergillosis. Posaconazole 600 mg/d is recommended in patients with acute myelogenous leukemia/myelodysplastic syndrome or undergoing allogeneic stem cell recipients with graft versus host disease for the prevention of invasive fungal infections and attributable mortality (Level A I). Fluconazole 400 mg/d is recommended in allogeneic stem cell recipients until development of graft versus host disease only (Level A I). Aerosolized liposomal amphotericin B is recommended during prolonged neutropenia (Level B II).

Renal coloboma syndrome, also known as papillorenal syndrome is an autosomal-dominant disorder characterized by ocular and renal malformations. Mutations in the paired-box gene, PAX2, have been identified in approximately half of individuals with classic findings of renal hypoplasia/dysplasia and abnormalities of the optic nerve. Prior to 2011, there was no actively maintained locus-specific database (LSDB) cataloguing the extent of genetic variation in the PAX2 gene and phenotypic variation in individuals with renal coloboma syndrome. Review of published cases and the collective diagnostic experience of three laboratories in the United States, France, and New Zealand identified 55 unique mutations in 173 individuals from 86 families. The three clinical laboratories participating in this collaboration contributed 28 novel variations in 68 individuals in 33 families, which represent a 50% increase in the number of variations, patients, and families published in the medical literature. An LSDB was created using the Leiden Open Variation Database platform: www.lovd.nl/PAX2. The most common findings reported in this series were abnormal renal structure or function (92% of individuals), ophthalmological abnormalities (77% of individuals), and hearing loss (7% of individuals). Additional clinical findings and genetic counseling implications are discussed.

Currently in the United States there is little direction for what constitutes sufficient guidelines for DNA mixture interpretation. While a standardized approach is not possible or desirable, more definition is necessary to ensure reliable interpretation of results is carried out. In addition, qualified DNA examiners should be able to review reports and understand the assumptions made by the analyst who performed the interpretation. Interpretation of DNA mixture profiles requires consideration of a number of aspects of a mixed profile, many of which need to be established by on-site, internal validation studies conducted by a laboratory's technical staff, prior to performing casework analysis. The relevant features include: criteria for identification of mixed specimens, establishing detection and interpretation threshold values, defining allele peaks, defining nonallele peaks, identifying artifacts, consideration of tri-allelic patterns, estimating the minimum number of contributors, resolving components of a mixture, determining when a portion of the mixed profile can be treated as a single source profile, consideration of potential additive effects of allele sharing, impact of stutter peaks on interpretation in the presence of a minor contributor, comparison with reference specimens, and some issues related to the application of mixture calculation statistics. Equally important is using sensible judgment based on sound and documented principles of DNA analyses. Assumptions should be documented so that reliable descriptive information is conveyed adequately concerning that mixture and what were the bases for the interpretations that were carried out. Examples are provided to guide the community. Interpretation guidelines also should incorporate strategies to minimize potential bias that could occur by making inferences based on a reference sample. The intent of this paper is to promote more thought, provide assistance on many aspects for consideration, and to support that more formalized mixture interpretation guidelines are developed.

We used an anonymous self-reported questionnaire to assess posttraumatic stress disorder symptoms, relationship concerns, and treatment preferences including interest in family-focused interventions among 100 National Guard Soldiers who were recently redeployed from Iraq or Afghanistan. We found that the majority of married or partnered soldiers were concerned about getting along with their partners, while the majority of parents were concerned about their child-rearing practices. Posttraumatic stress disorder symptoms were significantly associated with the degree of relationship concerns. Soldiers showed a striking preference for family-based interventions over individual treatment, highlighting the importance of developing family-based interventions tailored to address post-deployment mental health and co-occurring family problems.

Commonplaces about feminists, about women’s rights, bodies, and rhetoric participate in a cycle of violence and consciousness-raising. This paper articulates the particular way in which violent anti-feminist engagement in social media functions as disciplinary rhetoric. I contend that the goal of this rhetoric is to silence the women participating in public as feminist.

This study examined the influence of different sources of efficacy information on self-efficacy strength. Forty-eight women ranging from 18 to 40 years of age were recruited from a university population and randomly assigned to one of six groups. Each group received three sources of bench-press efficacy information (performance accomplishment, model, verbal message) presented in a different sequence. Bench-press efficacy strength was measured after each source of efficacy information. Results indicated that a performance accomplishment led to significantly stronger bench-press efficacy than did observation of a model, which in turn was more effective in strengthening efficacy than was hearing a verbal message. Second, performance accomplishment strengthened bench-press efficacy even when it followed one or both of the other sources of efficacy information. Finally, a verbal persuasion message was most effective in strengthening efficacy when it followed a performance accomplishment.

In this article, we argue that Niklas Luhmann has a lot to offer present-day planning theory. Until now, planning theory has been engaged with Luhmann's work only minimally. Convinced of its potential, we want to show how Luhmann's systems theory offers fresh insight into both limits and possibilities of planning in contemporary society. We argue that Luhmann's understanding of society as functionally differentiated into self-referentially closed subsystems (politics, economy, law, science, etc.) creates space for a complex and subtle analysis of planning practice. In particular, we look at the role of planning within an autopoietic account of society, and its ability to steer other social subsystems. Planning is seen as the form of steering aiming to coordinate processes of spatial organization, therefore an activity dealing with steering problems. We illustrate key concepts of the systems theory in brief analyses of planning situations and interpret these situations using the systems theoretical framework. The analyses center around the questions of planning's steering capacity and the role of the planner, thus creating linkages with mainstream discussions in planning theory.

The invasion of non-native earthworms (Lumbricus spp.) into a small number of intensively studied stands of northern hardwood forest has been linked to declines in plant diversity and the local extirpation of one threatened species. It is unknown, however, whether these changes have occurred across larger regions of hardwood forests, which plant species are most vulnerable, or with which earthworm species such changes are associated most closely. To address these issues we conducted a regional survey in the Chippewa and Chequamegon national forests in Minnesota and Wisconsin (U.S.A.), respectively. We sampled earthworms, soils, and vegetation, examined deer browse in 20 mature, sugar-maple-dominated forest stands in each national forest, and analyzed the relationship between invasive earthworms and vascular plant species richness and composition. Invasion by Lumbricus was a strong indicator of reduced plant richness in both national forests. The mass of Lumbricus juveniles was significantly and negatively related to plant-species richness in both forests. In addition, Lumbricus was a significant factor affecting plant richness in a full model that included multiple variables. In the Chequamegon National Forest earthworm mass was associated with higher sedge cover and lower cover of sugar maple seedlings and several forb species. The trends were similar but not as pronounced in Chippewa, perhaps due to lower deer densities and different earthworm species composition. Our results provide regional evidence that invasion by Lumbricus species may be an important mechanism in reduced plant-species richness and changes in plant communities in mature forests dominated by sugar maples.

OBJECTIVES: This report updates subnational estimates of the percentage of adults and children living in households that do not have a landline telephone but have at least one wireless telephone (i.e., wireless-only households). State-level estimates for 2012 are presented, along with estimates for selected U.S. counties and groups of counties, for other household telephone service use categories (e.g., those that had only landlines and those that had landlines yet received all or almost all calls on wireless telephones), and for one earlier 12-month period (July 2011-June 2012). METHODS: Small-area statistical modeling techniques were used to estimate the prevalence of adults and children living in households with various household telephone service types for 93 disjoint geographic areas that make up the United States. This modeling was based on 2007-2012 data from the National Health Interview Survey, 2006-2011 data from the American Community Survey, and auxiliary information on the number of listed telephone lines per capita in 2007-2012. RESULTS: The prevalence of wireless-only adults and children varied substantially across states. State-level estimates for 2012 ranged from 19.4% (New Jersey) to 52.3% (Idaho) of adults and from 20.6% (New Jersey) to 63.4% (Mississippi) of children.
