Renal function, calcium regulation, and time to hospitalization of patients with chronic kidney disease

BACKGROUND: Chronic kidney disease is associated with disruption of the endocrine system that distorts the balance between calcitriol, calcium, phosphate and parathyroid hormone in the calcium regulation system. This can lead to calcification of the arterial tree and increased risk of cardiovascular disease and death. In this study we develop a health metric, based on biomarkers involved in the calcium regulation system, for use in identifying patients at high risk for future high-cost complications. METHODS: This study is a retrospective observational study involving a secondary analysis of data from the kidney disease registry of a regional managed care organization. Chronic kidney disease patients in the registry from November 2007 through November 2011 with a complete set of observations of estimated glomerular filtration rate, calcitriol, albumin, free calcium, phosphate, and parathyroid hormone were included in the study (n = 284). Weibull regression model was used to identify the most significant lab tests in predicting “waiting time to hospitalization”. A multivariate linear path model was then constructed to investigate direct and indirect effects of the biomarkers on this outcome. RESULTS: The results showed negative significant direct effects of phosphate and parathyroid hormone on “waiting time to hospitalization”. Base on this result, the risk of hospitalization increases 16.8% for each 0.55 mg/dl increase in phosphate level and 13.5% for each 0.467 increase in the natural logarithm of parathyroid hormone. Positive indirect effects of calcitriol surrogate (calcidiol), free calcium, albumin and estimated glomerular filtration rate were observed but were relatively small in magnitude. CONCLUSION: Variables involved in the calcium regulation system should be included in future efforts to develop a quality of care index for Chronic Kidney disease patients

Ethical Leadership: Not Everyone Responds Equally

Theoretical frameworks associated with ethical leadership have not fully considered the nature of the leader–follower exchange, and, in addition, few studies have considered the impact of follower individual differences in reactions to ethical leadership. Our research extends the customary social exchange perspective of transactional and relational resources by accounting for the ideological resources (i.e., value-oriented principles) that can also imbue the leader–subordinate relationship. Second, differences in equity sensitivity are hypothesized to moderate the influence of ethical leadership on employee attachment to the organization. We predicted that the impact of ethical leadership on organizational commitment, job satisfaction, and organizational identification is greater for individuals with a more benevolent orientation. In Study 1 (N = 223), equity sensitivity moderated the influence of ethical leadership on organizational commitment and organizational identification. In Study 2 (N = 244), an interactive effect was found for the outcomes of organizational commitment and job satisfaction. We consider the theoretical implications of how and why ethical leadership influences follower attitudes and beliefs

Coordinating Interdependencies in an Open Source Software Project: A Replication of Lindberg, et al.

The current study is a full replication (conceptual and empirical) of “Coordinating Interdependencies in Online Communities: A Study of an Open Source Software Project” Lindberg et al (2016), which addresses the question of how OSS communities address unresolved interdependencies. Following the original study, we analyze project development data, archived in the GitHub repository, for the OSS project Rubinius. The analysis explores relationships among development and developer interdependencies as well as activity and order variation. Further, we extend the original study by examining the core relationships in the original study and investigating the external generalizability of the results by replicating the analysis on three analogous OSS projects: JRuby, mruby, and RubyMotion. These offer an opportunity to evaluate the generalizability of the original study to projects of different sizes and amount of activity, yet similar otherwise to the project in the original study. Another extension is the use of an additional control variable, length of activity sequence, which proves to have substantial implications of the study’s focal relationships. We find that three out of the four projects we analyze support the findings of the original study as it pertains to four relationships in the original study: order variation and developer interdependencies, activity variation and developer interdependencies, order variation and development interdependencies, and development and developer interdependencies. We also discuss the implications of our findings, especially in cases where the replication results differ from those in the original study and offer suggestions for future research that can help advance this stream of research

Diamondback Terrapin Bycatch Reduction Strategies for Commercial and Recreational Blue Crab Fisheries

Diamondback terrapin (Malaclemys terrapin) is considered a keystone species for its influence on community structure of tidal marshes. Terrapins exhibit strong habitat and nest site fidelity, and have relatively small home ranges (\u3c 2 km), so that sub-populations tend to be spatially discrete. Terrapins rely on open water, wetlands, and adjacent uplands at various stages of their life-cycle, so the quality and connectivity of these habitat patches is critical to population persistence. Terrapin is listed in Virginia as a species of Very High Conservation Need based on threats due to nest predation and drowning of adults in crab pots. Terrapin population declines, reduced growth, and changes in sex ratios have been directly attributed to bycatch mortality in commercial crab pots. Our overall project goal was to characterize essential terrapin habitats toward development of bycatch reduction strategies for managing commercial and recreational blue crab fisheries. In a pilot study area surrounding the mouth of the York River, Virginia, our approach was to 1) geospatially define suitable terrapin habitat based on natural features, 2) integrate spatial datasets to develop a Vulnerability Index of terrapin habitats and define potential resource conflict areas where crab pots correspond to essential terrapin habitat, and 3) conduct terrapin and crab pot counts in habitats with varying suitability to test predictions. Suitable terrapin habitat (full connectivity among habitat metrics) accounted for over 50% of all terrapin observations, and another 45% of observations occurred in areas where only one habitat metric was absent. In 96% of these cases, the absent metric was SAV presence. In contrast, full habitat connectivity was determined for only 5% of areas where terrapins were absent. Within the pilot study area during a two year retrieval program, 2872 derelict pots were removed. Of these, 22% were within shallow waters (≤ 2 m) where terrapins typically reside. Of the suitable terrapin habitat (70km2 ), 21% (15 km2 ) was considered vulnerable to crabbing pressures (10% highly and 11% moderately vulnerable). Approximately 15% of the study area was considered to be potential resource conflict areas for terrapin and crabbing. Candidate zones for the targeted application of blue crab fishery management actions to reduce terrapin bycatch include the Severn River, Perrin River, Guinea Marshes, and south of Gwynn Island. The integration of spatial information on terrapin habitat and crabbing pressure in a single framework will allow managers to identify areas where terrapins are most likely to encounter threats and target conservation efforts in those areas. In resource conflict areas, there are several management options that can be used in combination 1) Require use of bycatch reduction devices (BRDs) on commercial & recreational crab pots 2) Avoid particular habitats (e.g. small tidal creeks) or establish fishing exclusion zones 3) Educate – design public education programs to • promote the voluntary use of BRDs, and • communicate to recreational boaters the ramifications of severing buoy lines of active crab pots 4) Promote proper use of gear (e.g. retrieving pots regularly to minimize terrapin mortality). With further refinement to improve the predictability of terrapin occupancy, the terrapin habitat vulnerability model is transferable to all coastal areas where diamondback terrapins occur and where blue crabs are commercially and recreationally fished—from southern New England to Texas

A Formaldehyde Exposure Assessment Tool for Occupants of FEMA Temporary Housing Units

The report outlines the methodology used to develop a web-based tool to assess the formaldehyde exposure of the occupants of Federal Emergency Management Administration (FEMA) temporary housing units (THUs) after Hurricanes Katrina and Rita in 2005. Linear regression models were built using available data to retrospectively estimate the indoor temperature and relative humidity, formaldehyde emission factors and concentration, and hence the formaldehyde exposures. The interactive web-tool allows the user to define the inputs to the model to evaluate formaldehyde exposures for different scenarios
