Betting on Talent: Examining the Relationship between Employee Retention and Onboarding Programs
Get PDFThe expectations of employees in the United States continue to evolve as generational shifts occur in the workforce. The already raging war for talent has been fueled by the 2020 pandemic, which introduced new ways to work and different types of work opportunities. As a result, employees are re-evaluating their options and seeking ways to extract more value from their professional lives. In these circumstances, employee retention is a competitive advantage, and companies must consider how to retain their most desirable talent. Research in the organizational behavior domain shows that when employees hold values like those of their employing organization, they experience greater job satisfaction, increased organizational commitment, and higher intent to stay in the organization. Onboarding programs are widely accepted in the business community as a valuable opportunity to welcome new employees and introduce them to the values and culture of the organization, but organizations assign various weights and considerations to these programs as they can be costly to develop, execute, and maintain. In this article, we examine the relationship between employee retention and onboarding programs. We study whether a robust and well-executed onboarding program can mitigate employee attrition and can serve as a catalyst for employee retention in an organization
Behavior of Concrete Reinforced with Date Palm Fibers
Get PDFIn recent decades, researchers have begun to investigate innovative sustainable construction materials for the development of greener and more environmentally friendly infrastructures. The main purpose of this article is to investigate the possibility of employing date palm tree waste as a natural fiber alternative for conventional steel and polypropylene fibers (PPFs) in concrete. Date palm fibers are a common agricultural waste in Middle Eastern nations, particularly Saudi Arabia. As a result, this research examined the engineering properties of high‐strength concrete using date palm fibers, as well as the performance of traditional steel and PPF concrete. The concrete samples were made using 0.0%, 0.20%, 0.60%, and 1.0% by volume of date palm, steel, and polypropylene fibers. Ten concrete mixtures were made in total. Compressive strength, flexural strength, splitting tensile strength, density, ultrasonic pulse velocity (UPV), water absorption capability, and water permeability tests were performed on the fibrous‐reinforced high‐strength concrete. With a 1% proportion of date palm, steel, and polypropylene fibers, the splitting tensile strength improved by 17%, 43%, and 16%, respectively. By adding 1% fiber, flexural strength was increased by 60% to 85%, 67% to 165%, and 61% to 79%. In addition, date palm fibers outperformed steel and PPFs in terms of density, UPV, and water permeability. As a result, date palm fibers might potentially be employed in the present construction sector to improve the serviceability of structural elements
Competency-Based Social Work Education: 25 Years of Innovation & Leadership
Get PDFThe white paper chronicles the 25-year history of one graduate school of social work’s efforts in competency-based curriculum innovation. The authors argue that curriculum change is organizational change and share their experiences with a variety of curriculum assessment, design, and delivery efforts. Beginning with the development of the first social work competencies (labeled Abilities), pioneering efforts in assessment and holistic curricular design and delivery are reviewed. A new, one-semester, social work generalist curriculum is introduced. Emphasis is placed on the importance of developing a competency-based curriculum that is integrated both horizontally and vertically and that engages the social work student in active learning strategies. Special attention is focused on the iterative process of curricular innovation across platforms (on ground, online, and intensive weekend) and on developing a curriculum that continually seeks to integrate macro and micro social work practice. The opportunities, challenges, and lessons learned that arose from these efforts are identified and the reader is invited to consider how these experiences may be applied to their own school
Update on the Management of Vitamins and Minerals in Cystic Fibrosis
Get PDFAdvancements in respiratory and nutrition management have significantly improved the survival of patients with cystic fibrosis (CF). With the availability of several nutrition interventions such as oral/enteral nutrition supplements, enteric-coated pancreatic enzymes, and water-miscible CF-specific vitamin supplements, frank vitamin deficiencies—with the exception of vitamin D—are rarely encountered in current clinical practice. Whereas they were previously considered as micronutrients, our current understanding of fat-soluble vitamins and minerals as antioxidants, immunomodulators, and disease biomarkers has been evolving. The impact of highly effective modulators on the micronutrient status of patients with CF remains elusive. This narrative review focuses on the updates on the management of fat-soluble vitamins and other micronutrients in CF in the current era and identifies the gaps in our knowledge
Urate-Lowering Therapy for Patients with Gout on Hemodialysis
Get PDFObjective: Gout is the most common form of inflammatory arthritis and is caused by deposition of monosodium urate crystals resulting from a high burden of uric acid (UA). High UA burden also has been associated with increased morbidity and mortality in the general population and progression to chronic kidney disease. In persons with gout and end-stage renal disease (ESRD), prior studies suggest that UA levels decrease after initiation of hemodialysis (HD). We evaluated UA level and the use of urate-lowering therapies (ULTs) in patients with gout and ESRD on HD. Methods: We performed a retrospective review of patients with gout and ESRD seen at a large urban public hospital (The MetroHealth System). We extracted data from the medical record (Epic) for patients diagnosed with gout and ESRD on HD. The main outcomes were the UA level and the use of ULTs before and after HD initiation. Results: We identified 131 patients with gout on HD. Of these, 21 patients had crystal proven gout diagnosis, 10 of whom had data on UA level pre-HD and post-HD and were included in the analysis. For the total sample (N = 21), the mean age was 65 years, 7 were female and 20 were African American. Mean pre-HD and post-HD UA levels were 8.4 and 3.98 mg/dL respectively. Twenty-one patients were receiving ULT pre-HD, 11 discontinued post-HD. Conclusion: Among patients with gout and ESRD, we observed a decrease in UA level associated with initiation of HD. For this group, discontinuation of ULTs may be appropriate
Survey Tools for Measuring Research or Evidence‐Based Practice Constructs in Dietetics: A Narrative Review
Get PDFBackground: Exact quantification of research conducted by dietitians and tracking the effectiveness of interventions or training programs to increase either evidence-based practice (EBP) or research behaviours have been hampered by the variety of tools used to measure these constructs. Methods: In this narrative review, we identified and classified the various tools previously used to measure constructs related to research and/or EBP in the dietetics profession, and to summarise estimates of the constructs measured. Results: We identified and classified 15 scored tools that had been used at least once in the dietetics profession and extracted tool parameter estimates from 22 resulting papers. We also identified six unscored tools and three qualitative studies. The most frequent constructs measured were attitudes and behaviours. Very few tools measured objective knowledge (skills). No objective measures of research outputs were identified. Several tools were closely related to one another. Conclusions: Even when tools were used across multiple papers, reporting method varied making comparisons difficult. This review should encourage future researchers to utilise existing tools when possible, and encourage the development or adaptation and testing of tools that fill identified gaps. The constructs measured by the tools identified may also provide a starting point for the development of educational interventions aiming to increase research or EBP skills among dietitians. Only by using consistent tools will the dietetics profession be able to track the progress in increasing research conduct and EBP implementation over time

Riverine Plastic Pollution in Asia: Results from a Bibliometric Assessment
Get PDFRivers are important ecosystems, vital to the livelihoods of hundreds of millions of humans and other species. Despite their environmental, social, and economic importance, current use of rivers is unsustainable, due to a combination of solid waste and high levels of pollutants. Plastic materials are among the most predominant of such pollutants. Based on the need for additional research in this area, this study examines pressures put to rivers and explores trends related to riverine plastic pollution, with a focus on Asia. Apart from the bibliometric analysis, and relying on the collected information, examples describing the drivers of riverine plastic pollution in a sample of Asian countries are described, outlining the specific problem and its scope. Among some of the results obtained from it, mention can be made to the fact that much of the literature focuses on plastic pollution as a whole and less on one of its most significant ramifications, namely microplastics. Additionally, there is a need related to data availability on riverine plastic data and improving the understanding of transport mechanisms in relation to riverine plastic emission into the ocean. The results from this study illustrate the significance of the problems posed by plastic waste to Asian rivers and point out the fact that there are still significant gaps in respect of regulations and standards, which prevent improvements that are highlighted in this study. Based on the results of this bibliometric assessment, specific measures via which levels of riverine plastic pollution may be reduced are presented, bringing relevant new insights on this topic beyond the existing reviews
Incorporating Baryon-Driven Contraction of Dark Matter Halos in Rotation Curve Fits
Get PDFThe condensation of baryons within a dark matter (DM) halo during galaxy formation should result in some contraction of the halo as the combined system settles into equilibrium. We quantify this effect on the cuspy primordial halos predicted by DM-only simulations for the baryon distributions observed in the galaxies of the SPARC database. We find that the DM halos of high surface brightness galaxies (with Σeff 3; 100L pc-2 at 3.6 μm) experience strong contraction. Halos become more cuspy as a result of compression: the inner DM density slope increases with the baryonic surface mass density. We iteratively fit rotation curves to find the balance between initial halo parameters (constrained by abundance matching), compression, and stellar mass-to-light ratio. The resulting fits often require lower stellar masses than expected for stellar populations, particularly in galaxies with bulges: stellar mass must be reduced to make room for the DM it compresses. This trade off between dark and luminous mass is reminiscent of the cusp-core problem in dwarf galaxies, but occurs in more massive systems: the present-epoch DM halos cannot follow from cuspy primordial halos unless (1) the stellar mass-to-light ratios are systematically smaller than expected from standard stellar population synthesis models, and/or (2) there is a net outward mass redistribution from the initial cusp, even in massive galaxies widely considered to be immune from such effects
A Blind Benchmark of Analysis Tools to Infer Kinetic Rate Constants From Single-Molecule Fret Trajectories
Get PDFSingle-molecule FRET (smFRET) is a versatile technique to study the dynamics and function of biomolecules since it makes nanoscale movements detectable as fluorescence signals. The powerful ability to infer quantitative kinetic information from smFRET data is, however, complicated by experimental limitations. Diverse analysis tools have been developed to overcome these hurdles but a systematic comparison is lacking. Here, we report the results of a blind benchmark study assessing eleven analysis tools used to infer kinetic rate constants from smFRET trajectories. We test them against simulated and experimental data containing the most prominent difficulties encountered in analyzing smFRET experiments: different noise levels, varied model complexity, non-equilibrium dynamics, and kinetic heterogeneity. Our results highlight the current strengths and limitations in inferring kinetic information from smFRET trajectories. In addition, we formulate concrete recommendations and identify key targets for future developments, aimed to advance our understanding of biomolecular dynamics through quantitative experiment-derived models
