Recruitment Analysis Of The Cooperative Labor Force In Improving Human Resources

Employment recruits of an organization have not improved the standards of selection so that the resulting workforce does not meet the qualifications for the jobs offered. This phenomenon also applies to cooperatives as business organizations. Co-operatives are one of the forums that are quite developed in increasing their business. Currently, the existing human resources are managed simply, the function of personnel management is charged as Manager as the manager of the cooperative. The recruitment process is the earliest stage in personnel management, so if it is ignored it can disrupt the company's performance.The purposes of this study are 1) To find out the labor recruitment process that has been implemented so far. 2) To find out the existing workforce recruitment process. The method used in this research is descriptive qualitative, namely as a research process that produces qualitative data in the form of written or spoken words from the observed person or actor.The results showed that the recruitment process in cooperatives was carried out in a simple but complete and selective manner. The process includes forecasting work needs, selection, an orientation that is still simple but complete enough and based on criteria, standards, or specifications for the real needs of the existing job or position. Recruitment sources are utilized optimally so that professionalism is established. The cooperative uses criteria in the Indonesian economy, namely in the form of workforce skills which include moral and physical health, reason (good knowledge), education and training, work perfection.

Body mass index prediction rule for mid-upper arm circumference: the atherosclerosis risk in communities study.

Electronic health records (EHR) are a convenient data source for clinical trial recruitment and allow for inexpensive participant screening. However, EHR may lack pertinent screening variables. One strategy is to identify surrogate EHR variables which can predict the screening variable of interest. In this article, we use BMI to develop a prediction rule for arm circumference using data from the Atherosclerosis Risk in Communities (ARIC) Study. This work applies to EHR patient screening for clinical trials of hypertension. We included 11 585 participants aged 52-75 years with BMI and arm circumference measured at ARIC follow-up visit 4 (1996-1998). We selected the following arm circumference cutpoints based on the American Heart Association recommendations for blood pressure (BP) cuffs: small adult (≤26 cm), adult (≤34 cm) and large adult (≤44 cm). We calculated the sensitivity and specificity of BMI values for predicting arm circumference using receiver operating characteristic curves. We report the BMI threshold that maximized Youden's Index for each arm circumference upper limit of a BP cuff. Participants' mean BMI and arm circumference were 28.8 ± 5.6 kg/m2 and 33.4 ± 4.3 cm, respectively. The BMI-arm circumference Pearson's correlation coefficient was 0.86. The BMI threshold for arm circumference≤26 cm was 23.0 kg/m2, arm circumference≤34 cm was 29.2 kg/m2 and arm circumference≤44 cm was 37.4 kg/m2. Only the BMI threshold for arm circumference≤34 cm varied significantly by sex. BMI predicts arm circumference with high sensitivity and specificity and can be an accurate surrogate variable for arm circumference. These findings are useful for participant screening for hypertension trials. Providers can use this information to counsel patients on appropriate cuff size for BP self-monitoring.

Water quality limitations for tadpoles of the Wood Frog in the northern Great Plains, Canada.

Some wetlands in the northern Great Plains support hundreds to thousands of late-stage tadpoles providing important sources of recruitment to the Wood Frog (Lithobates sylvaticus) population while many other wetlands produce none. Relationships between water quality and late-stage tadpole abundance were determined to identify the water quality parameters associated with tadpole abundance. Water samples were collected, and late-stage tadpole abundances were assessed once each year in late June for 12years in 26 wetlands. Catch or abundance was the number of tadpoles captured in 30min with a dip-net. The catch of tadpoles was variable both among wetlands and over the long-term for individual wetlands, and ranged from 0 to several hundred individuals. Wood Frog tadpoles were especially sensitive to sodium and chloride concentrations. At Cl concentrations less than 5mg/L, occupancy for late-stage tadpoles was 84%, and declined by about 8% for each 5mg/L increase in Cl to 40.1mg/L Cl, the maximum concentration associated with the detection of tadpoles. Optimal water quality for late-stage Wood Frog tadpoles included low concentrations of Na [Formula: see text] = 8.1mg/L), and Cl [Formula: see text] = 4.2mg/L) relative to total dissolved solids and other ions, and high concentrations of phosphorus. In a landscape where ion concentrations in wetlands can range over 3 orders of magnitude, water quality analyses suggest that abundant Wood Frog tadpole populations occur in wetlands dominated by snow-melt runoff with its characteristic low ion concentrations. The present study highlights the importance to amphibian conservation of the water quality environment of tadpole habitat.

Population demographics of golden perch (

An understanding of population demographics and life history processes is integral to the rehabilitation of fish populations. In Australia’s highly modified Murray–Darling Basin, native fish are imperilled and fish deaths in the Darling River in 2018–19 highlighted their vulnerability. Golden perch (Macquaria ambigua) is a long-lived percichthyid that was conspicuous in the fish kills. To guide population rehabilitation in the Darling River, pre-fish kill age structure, provenance and movement of golden perch were explored using otolith microstructure and chemistry (87Sr/86Sr). Across the Lower and Mid-Darling River, recruitment was episodic, with dominant cohorts associated with years characterised by elevated discharge. There was substantial variability in age structure, recruitment source and movement patterns between the Lower and Mid-Darling River. In the Mid-Darling River, tributaries were an important recruitment source, whereas in the Lower Darling fish predominantly originated in the Darling River itself. Downstream movement of juveniles, upstream migration of adults and return movements to natal locations were important drivers of population structure. Restoring resilient golden perch populations in the Darling River will be reliant on mitigating barriers to movement, promoting a connected mosaic of recruitment sources and reinstating the hydrological and hydraulic factors associated with spawning, recruitment and dispersal. Globally, increasing water resource development and climate change will necessitate such integrated approaches to the management of long-lived migratory riverine fishes.

Rapid deployment of a community engagement study and educational trial via social media: implementation of the UC-COVID study

BackgroundIn response to the COVID-19 pandemic and associated adoption of scarce resource allocation (SRA) policies, we sought to rapidly deploy a novel survey to ascertain community values and preferences for SRA and to test the utility of a brief intervention to improve knowledge of and values alignment with a new SRA policy. Given social distancing and precipitous evolution of the pandemic, Internet-enabled recruitment was deemed the best method to engage a community-based sample. We quantify the efficiency and acceptability of this Internet-based recruitment for engaging a trial cohort and describe the approach used for implementing a health-related trial entirely online using off-the-shelf tools.MethodsWe recruited 1971 adult participants (≥ 18 years) via engagement with community partners and organizations and outreach through direct and social media messaging. We quantified response rate and participant characteristics of our sample, examine sample representativeness, and evaluate potential non-response bias.ResultsRecruitment was similarly derived from direct referral from partner organizations and broader social media based outreach, with extremely low study entry from organic (non-invited) search activity. Of social media platforms, Facebook was the highest yield recruitment source. Bot activity was present but minimal and identifiable through meta-data and engagement behavior. Recruited participants differed from broader populations in terms of sex, ethnicity, and education, but had similar prevalence of chronic conditions. Retention was satisfactory, with entrance into the first follow-up survey for 61% of those invited.ConclusionsWe demonstrate that rapid recruitment into a longitudinal intervention trial via social media is feasible, efficient, and acceptable. Recruitment in conjunction with community partners representing target populations, and with outreach across multiple platforms, is recommended to optimize sample size and diversity. Trial implementation, engagement tracking, and retention are feasible with off-the-shelf tools using preexisting platforms.Trial registrationClinicalTrials.gov NCT04373135. Registered on May 4, 2020

Impact of gyral geometry on cortical responses to surface electrical stimulation: insights from experimental and modeling studies

Objective. Invasive simultaneous stimulation and recording from intracranial electrodes and microwire arrays were used to investigate direct cortical responses to single pulses of electrical stimulation in humans. Approach. Microwire contacts measured surface potentials in cortical microdomains at a distance of 2–6 mm from the intracranial electrode. Direct cortical responses to stimulation (<20 ms) consisted of a larger surface negative potentials. Main results. The latencies of these responses were directly or inversely correlated with distances between the intracranial electrode and microwire contacts. We hypothesize that surface negative potentials reflected local synchronous depolarization of apical dendrites of pyramidal neurons in cortical microdomains in the superficial cortical layer and resulted from the activation of gray matter axons that delivered excitatory inputs to apical dendrites after cortical stimulation. We further hypothesized that the positive or inverse distance-latency correlations of the recorded negative responses were measured depending on whether activation of neurons originated at one (crown) or multiple (crown, lip, bank) sites throughout the gyrus simultaneously. The inverse distance-latency correlations then reflected the spatiotemporal superposition of different nearby sources of neuronal recruitment in the gyrus. To prove this hypothesis, we built an anatomically informed and biophysically realistic cortical network model and simulated early responses of cortical neurons to electrical stimulation in this cortical network model. The model simulations yielded negative potentials in simulated microdomains in the cortical model consistent with those recorded from humans. The model predicted sensitivity of cortical responses to the alignment of the stimulating electrode and microwire array with respect to the cortical gyrus and confirmed that gyral geometry has a major impact on direct neuronal recruitment, the timing, and the time course of neuronal activation in cortical microdomains. Significance. In this work, we demonstrated how the high-resolution forward network models can be used for better understanding and detailed prediction of cortical stimulation effects. Accurate predictive modeling tools are needed for the progress of brain stimulation therapies.

Recruitment and Selection Practices of Construction Employers in Rwanda

Human resources play a key role in the achievement of construction projects. This study investigated the recruitment practices of construction employers in Rwanda. The problem of the study is the lack of empirical evidence to support the recruitment and selection practices of construction employers in Rwanda. Similar studies are abundant in other sectors of the economy but very scarce in the construction industry. The descriptive survey research design was adopted for the study. A closed-ended questionnaire was used for data collection. The population of the study are the construction organisations that employ construction workers in Rwanda. Hence, the population of the study is the 580 construction organisations that are officially working in Rwanda. A sample of 80 firms used for the study were determined with the use of Slovin’s formula. The findings of the study indicated that requests for the curriculum vitae, cover letter, face-to-face interview, submission of applications with key information of education/work experience and knowledge test to measure job specific knowledge are the prevalent strategies of recruiting and selecting staff in the construction industry. The prominent sources of recruitment and selection are internship performance, internal advertisement, and local newspaper advertisement. Based on the findings of the study, it was recommended that construction organizations should study and adopt the recruitment and selection strategies that have given them the most effective results. It was also recommended that the organisation should stick to the most effective sources of recruitment and selection for their organisations

Disparities by Race and Ethnicity Among Adults Recruited for a Preclinical Alzheimer Disease Trial

Underrepresentation of many racial/ethnic groups in Alzheimer disease (AD) clinical trials limits generalizability of results and hinders opportunities to examine potential effect modification of candidate treatments. To examine racial and ethnic differences in recruitment methods and trial eligibility in a multisite preclinical AD trial. This cross-sectional study analyzed screening data from the Anti-Amyloid in Asymptomatic AD study, collected from April 2014 to December 2017. Participants were categorized into 5 mutually exclusive ethnic/racial groups (ie, Hispanic, Black, White, Asian, and other) using participant self-report. Data were analyzed from May through December 2020 and included 5945 cognitively unimpaired older adults between the ages of 65 and 85 years screened at North American study sites. Primary outcomes included recruitment sources, study eligibility, and ineligibility reasons. To assess the probability of trial eligibility, regression analyses were performed for the likelihood of being eligible after the first screening visit involving clinical and cognitive assessments. Screening data were included for 5945 participants at North American sites (mean [SD] age, 71.7 [4.9] years; 3524 women [59.3%]; 5107 White [85.9%], 323 Black [5.4%], 261 Hispanic [4.4%], 112 Asian [1.9%], and 142 [2.4%] who reported race or ethnicity as other). Recruitment sources differed by race and ethnicity. While White participants were recruited through a variety of sources, site local recruitment efforts resulted in the majority of Black (218 [69.2%]), Hispanic (154 [59.7%]), and Asian (61 [55.5%]) participants. Participants from underrepresented groups had lower mean years of education (eg, mean [SD] years: Hispanic participants, 15.5 [3.2] years vs White participants, 16.7 [2.8] years) and more frequently were women (226 [70.0%] Black participants vs 1364 [58.5%] White participants), were unmarried (184 [56.9%] Black participants vs 1364 [26.7%] White participants), and had nonspousal study partners (237 [73.4%] Black participants vs 2147 [42.0%] White participants). They were more frequently excluded for failure to meet cognitive inclusion criteria (eg, screen failures by specific inclusion criteria: 147 [45.5%] Black participants vs 1338 [26.2%] White participants). Compared with White participants, Black (odds ratio [OR], 0.43; 95% CI, 0.34-0.54; P < .001), Hispanic (OR, 0.53; 95% CI, 0.41-0.69; P < .001), and Asian participants (OR, 0.56; 95% CI, 0.38-0.82; P = .003) were less likely to be eligible after screening visit 1. Racial/ethnic groups differed in sources of recruitment, reasons for screen failure, and overall probability of eligibility in a preclinical AD trial. These results highlight the need for improved recruitment strategies and careful consideration of eligibility criteria when planning preclinical AD clinical trials.

Sleep and quality of life in lung cancer patients and survivors.

Lung cancer patients and survivors are vulnerable to disturbed sleep and impaired quality of life (QOL) across the continuum of illness. Few studies have sought to identify predictors of QOL using well-validated measures of both sleep quality and QOL in this population. The purpose of this study was to examine factors associated with lung cancer that are predictive of QOL in adult lung cancer patients and survivors in the outpatient setting. Cross-sectional data collected exclusively in the outpatient setting from three lung cancer clinics in the Northeastern United States were pooled and analyzed. The pooled sample (N = 103) data included cancer type and stage, body mass index, Pittsburgh Sleep Quality Index, and Functional Assessment of Cancer Treatment-Lung information. Significant correlations between sleep quality, lung cancer symptom severity, and QOL were observed. Sleep quality and lung cancer symptoms were found to be statistically significant predictors of QOL. No significant differences in QOL were found based on cancer type or recruitment source. Demographic factors and cancer stage were also not predictive of overall QOL. Lung cancer symptoms and sleep quality were important determinants of QOL in this pooled sample of lung cancer patients and survivors. Patients and survivors of lung cancer require routine screening for sleep disturbance, lung cancer symptoms, and QOL needs. Nurse practitioners can help improve QOL in this population by screening for and treating sleep disturbance and lung cancer symptoms.

Recruiting cisgender female couples for health disparity-focused daily diary research: challenges, successes, and lessons learned

ABSTRACT The underlying mechanisms of sexual minority women’s (SMW’s) physical and mental health disparities are not well understood. Relationship factors are particularly understudied, and data are rarely collected from both same-sex female partners. Most research is cross sectional limiting our understanding of day-to-day experiences. This paper describes the feasibility of recruiting a large sample of SMW and their female partners for a disparity-focused daily diary study investigating alcohol use and mental health. A firm specializing in sexual minority market research assisted with recruitment from multiple sources and conducted an initial pre-screening of SMW and their female partners, at least one of whom drank alcohol regularly. A total of 4182 individuals completed the pre-screener, and information for 930 individuals (465 couples) was sent to the research team. Then, 376 individuals (188 couples) completed the study screener, met the inclusion criteria, and were invited to participate. Ultimately, 326 individuals (163 couples) consented and completed baseline. A total of 321 individuals, from 162 couples, began the daily diary portion of the study. Compliance with study procedures was excellent. The use of multiple recruitment sources increased the diversity of the sample. Challenges to recruitment, changes in protocol, and characteristics of the final sample are discussed.RM

Temporal trends in semen concentration and count among 327 373 Chinese healthy men from 1981 to 2019: a systematic review.

Are there temporal trends of sperm concentration (SC) and total sperm count (TSC) in Chinese healthy males from 1981 to 2019? Our result indicated a temporal decrease in SC and TSC among 327 373 healthy Chinese men in the recent four decades. A review of 61 papers reported a temporal decline in SC and TSC from 1938 to 1990. This trend was later confirmed by a systematic review of 185 published papers from 1981 to 2013. However, the majority of the included individuals were from western countries. In China, whether SC and TSC have declined remains controversial. This systematic review of published articles used data extracted from Pubmed, Science Direct, Embase, China-National-Knowledge-Infrastructure (CNKI) and Wanfang Data to assess changes in SC and TSC in China from 1981 to 2019. A total of 111 studies including 327 373 individuals who provided semen samples from 1981 to 2019 were extracted for the present analysis. Study selection and data extraction were performed by two independent researchers. The trends in SC and TSC were analysed using liner-regression and meta-regression before and after adjusting for potential covariates. Moreover, subgroups, categorised based on geographic region, fertility status or recruitment source, were also analysed. SC declined significantly (slope liner-regression = -0.748 million/ml/year; P = 0.005; slope meta-regression = -0.824 million/ml/year; P < 0.001) between 1981 and 2019 in China. Trends for TSC was similar to that for SC (slope liner-regression = -2.073 million/year; P = 0.032; slope meta-regression = -2.188 million/year; P = 0.003). In subgroup meta-regression analyses, males with definite fertility had continuous declines in SC (slope northern group=-2.268, P = 0.009; slope southern group=-1.014, P = 0.009) and TSC (slope northern group=-9.675, P = 0.010; slope southern group=-3.215, P = 0.042). However, in the unselected group, where fertility status was unknown, the obvious downward trend in SC was only seen in males from Northern regions (slope = -0.836, P = 0.003). Another subgroup analysis demonstrated that obvious decreases in SC (slope = -1.432, P < 0.001) and TSC (slope=-4.315, P = 0.001) were only seen in volunteer groups but not in pre-pregnancy examination groups and other recruitment groups. The results changed minimally in multiple sensitivity analyses. The validity of the meta-analysis results was limited mainly by the quality of the included studies. Additionally, our study spanned many decades and the recommended criteria for some semen parameter assessments have significantly changed, which may bring about some unavoidable bias. Moreover, the data remain insufficient especially in some provinces of China. The present study is the first study to report significant decreases in SC and TSC in 327 373 healthy Chinese men between 1981 and 2019, indicating a serious reproductive health warning. Further studies on the causes of the declines are urgently needed.

Analysis of Recruitment System and Effective Selection for Front-Line Staff Outsource at Pt Garuda Indonesia (Persero) TBK

PT Garuda Indonesia (Persero) TBK is a state-owned company whose business focus is transportation services pax and cargo. In carrying out its business processes, the Garuda Indonesia Company has a cooperation with PT Perdana Perkasa Elastindo (Persaels) in providing outsourced labor for front-line staff. The performance evaluation data of the front-line outsource staff stationed at Garuda Indonesia Medan Branch for the last 3 years (2015, 2016 and 2017), it was found that around 40% of the total front-line staff did not show good performance according to the company's needs. The purpose of this research is to identify the factors exist in the dimensions of the recruitment and selection system that are constraints, and formulate an effective recruitment process design and selection for outsourced front-line staff by outsourced service providers. The requirements of front-line staff met with the company needs as outsourced service users. The data analysis used descriptive qualitative technique. The results of the research on several factors from the existing recruitment and selection dimensions indicate that the factors of Job description, Job Requirements, Sources of recruitment, interview process and consistency in the implementation of the selection test are factors that become obstacles in producing competent outsourced front-line staff according to the needs of the company PT Garuda Indonesia ( Persero) TBK. Keywords: Recruitment system, front-line staff outsource, PT Garuda Indonesia (Persero) TBK.

Assessing the Viability of American Horseshoe Crab (Limulus polyphemus) Embryos in Salt Marsh and Sandy Beach Habitats.

AbstractFor animal embryos that develop externally, the physio-chemical environment can substantially affect offspring viability. In the case of the American horseshoe crab (Limulus polyphemus), sediment conditions along estuarine shorelines influence development rates and embryonic viability. Sandy beach habitats are considered to have optimal conditions for horseshoe crab embryonic development; however, spawning is often observed outside of these optimal habitats, in areas such as salt marshes, where reduced oxygen availability is thought to decrease the viability of eggs laid in these sediments. We excavated horseshoe crab eggs, embryos, and trilobites laid naturally in marsh and beach sediments in South Carolina to compare their development and viability between habitats. We found all developmental stages in both marsh and beach habitats. For two of three sampling areas, trilobites were more likely to be found at beaches than at marshes. Multivariate analyses demonstrate that the prevalence of early and middle developmental stages was similar between habitats but that beaches had a greater proportion of late-stage trilobites than marshes. The lower likelihood of finding trilobites at some marshes may reflect differences in spawning phenology between habitats or reduced rates of embryonic development in marshes compared to beaches, leading to potentially different developmental timelines rather than a true reduction in viability. Nevertheless, the substantial proportions of eggs laid in salt marshes that survive to the trilobite stage indicate that spawning in this habitat could represent a previously underappreciated source of recruitment for horseshoe crab populations that may need to be incorporated into population assessments.

Impact of Recruitment and Selection Process on the Performance of Public Enterprises. A Study of the Nigeria Railway Corporation.

This study examined the impact of the recruitment and selection process on the performance of employees in the Nigerian Railway Corporation. The population of the study is six hundred and fifty-six (656) staff, and a sample size of two hundred and forty-eight (248) was drawn using Taro Yamane's sample size determination technique. Survey and interview methods were used for data collection. The Ordinary Least Squares method of regression was used to analysed the data. Findings revealed that the recruitment and selection process has a significant influence on the train movement schedule of the Corporation, and Hypothesis one was therefore rejected. It also discovered that the recruitment and selection process, on average, have significant effects on the train maintenance culture of the Corporation, and Hypothesis two was similarly rejected. Finally, it equally revealed that the recruitment and selection process greatly elicited employees' innovation, particularly in the recruitment source and recruitment selection policy, consequently rejecting Hypothesis three. The study concluded that the recruitment and selection process greatly influenced employees' performance in the Corporation regarding hiring appropriate skills that handled train movement schedules except for the train maintenance culture. The study recommended that the Corporation review recruitment hiring policy to focus on meritocracy and brace up to internal and external sources of hiring appropriate personnel for train maintenance in the Corporation. Also, there should be no government or political interference regarding recruitment source and recruitment policy as being done now to stimulate employee selection.

Rural Height Penalty or Socioeconomic Penalization? The Nutritional Inequality in Backward Spain.

This article studies the evolution of nutritional inequality, measured through the male adult height, in one of the poorest regions of Spain, in southwestern Europe: Extremadura. With a wide sample of statures of recruits born between 1855 and 1979, conscripted between 1876 and 2000, the research delves into the urban-rural height gap using coefficients of variation, tests of equality of means and proxy variables of a socioeconomic nature. The results of the analysis reveal that the strong anthropometric growth that Extremadura experienced since the last decades of the 19th century was accompanied by a less internal inequality. The lower heterogeneity did not eliminate, however, the urban-rural height gap during the period under study. In this sense, despite the absence of environmental differences between urban and rural areas in Extremadura, there was a clear rural height penalty in the region from the mid-19th century to the late 20th century. Rural punishment was fundamentally related to the greater presence of agrarian workers and the lower presence of wealthy families in villages and small towns. On the contrary, educational differences or differences in terms of nutritional health were not as decisive in the rural height penalization, at least when such differences are measured with the sources of military recruitment.

Understanding drivers of wild oyster population persistence

Persistence of wild Pacific oyster, Magallana gigas, also known as Crassostrea gigas, has been increasingly reported across Northern European waters in recent years. While reproduction is inhibited by cold waters, recent warm summer temperature has increased the frequency of spawning events. Although correlation between the increasing abundance of Pacific oyster reefs in Northern European waters and climate change is documented, persistence of wild populations may also be influenced by external recruitment from farmed populations and other wild oyster populations, as well as on competition for resources with aquaculture sites. Our understanding of the combined impact of the spawning frequency, external recruitment, and competition on wild population persistence is limited. This study applied an age-structured model, based on ordinary differential equations, to describe an oyster population under discrete temperature-related dynamics. The impact of more frequent spawning events, external recruitment, and changes in carrying capacity on Pacific oyster density were simulated and compared under theoretical scenarios and two case studies in Southern England. Results indicate that long term persistence of wild oyster populations towards carrying capacity requires a high frequency of spawning events but that in the absence of spawning, external recruitment from farmed populations and other wild oyster populations may act to prevent extinction and increase population density. However, external recruitment sources may be in competition with the wild population so that external recruitment is associated with a reduction in wild population density. The implications of model results are discussed in the context of wild oyster population management.

Impacts of injury severity on long-term outcomes following motor vehicle crashes

BackgroundThere is growing evidence that a range of pre-injury, injury related and post-injury factors influence social and health outcomes across the injury severity spectrum. This paper documents health related outcomes for people with mild, moderate and severe injury after motor vehicle crash (MVC) injuries in New South Wales, Australia.MethodsThis inception cohort study followed 2019 people injured in MVCs, for 6 and 12 months post-injury. We categorised moderate injury as hospital length-of-stay (LOS) of 2–6 days and Injury Severity Score (ISS) of 4–11, while severe injury as LOS ≥7 days or ISS ≥ 12. We examined differences in paid work status, 12-Item Short Form Survey (SF12), EQ-5D and World Health Organisation Disability Assessment Schedule II (WHODAS) outcomes longitudinally from baseline to 12 months between levels of injury severity using linear mixed models for repeated measures. We first considered minimally sufficient adjustment factors (age, sex, crash role, perceived danger in crash, pre-injury health, pre-injury EQ-5D, recruitment source), and then more extensive adjustments including post-injury factors. The presence of mediating pathways for SF-12 Physical Component Summary (PCS) and Mental Component Summary (MCS) via post-injury factors was evaluated.ResultsBased on hospital length of stay (LOS), 25 and 10% of participants sustained moderate and severe injuries, respectively, while 43 and 4% had these injuries based on ISS. Twelve months post-injury LOS ≥7 days versus ≤1 day was associated with an estimated 9 units lower mean SF12 PCS using a minimally sufficient adjustment model, and LOS ≥ 7 days was associated with a 3 units lower mean SF12 MCS score. Mediation analyses (LOS ≥ 7 days vs ≤1 day) found for SF12 MCS outcomes, effects of injury severity were small and mostly indirect (direct effect − 0.03, indirect effect − 0.22). Whereas for SF12 PCS outcomes the effect of having a more severe injury rather than mild were both direct and indirect (direct effect − 0.50, indirect effect − 0.38).ConclusionsIndividuals with severe injuries (those with LOS ≥ 7 days and ISS 12+) had poorer recovery 12 months after the injury. In addition, post-injury mediators have an important role in influencing long-term health outcomes.Trial registrationAustralia New Zealand Clinical trial registry identification number - ACTRN12613000889752.

Suitability of an Upper Mississippi River Tributary for Invasive Carp Reproduction

AbstractInvasive carp are expanding throughout the upper Mississippi River basin and are of great concern due to their potential economic and ecological impacts. Identification of spawning locations provides critical information on recruitment sources to evaluate potential management strategies. Our objective was to create and validate a spawning habitat suitability model of the Des Moines River, Iowa, during low‐, average‐, and high‐water‐level conditions. Backwater availability, abundance of hardpoints (structures that create turbulence), river gradient and sinuosity, water temperature, and continuously free‐flowing river lengths were used as model parameters. The model was compared to back‐calculated spawning locations from invasive carp eggs collected in 2014–2015. Turbulent hardpoints, river sinuosity, and gradient were not significant predictors of invasive carp spawning locations, and backwater availability in the 25 river kilometers downstream of each reach was inversely correlated with invasive carp spawning locations. Invasive carp eggs were not caught in 2014 despite optimal spawning conditions, revealing that spawning may have high interannual variation. This study suggests that predicting invasive carp reproduction may require variables in addition to those currently proposed.

Abstract PS8-11: Recruitment strategies for enrollment of high-risk women to a randomized controlled trial of web-based decision support tools to increase breast cancer chemoprevention

Abstract Background: Less than 10 % of those identified as eligible for clinical trials are recruited. Recruitment for chemoprevention trials poses challenges as it is often difficult to identify unaffected patients at high risk for cancer. Barriers to recruitment include personal perceptions of the benefits, fear of trials, low recruitment of minorities, language barriers, transportation costs, and complex study designs. In this study, we identified five potential sources of recruitment that could be collectively leveraged to identify women at high risk for breast cancer to improve recruitment yield. Methods: A total of 300 high-risk women and 50 healthcare providers were recruited and randomized to access web-based decision support tools in combination with standard educational materials or standard educational materials alone. Patient inclusion criteria included: 1) women, age 35-75 years; 2) English or Spanish-speaking; 3) no previous breast cancer diagnosis; 4) no prior use of selective estrogen receptor modulators (SERMs) or aromatase inhibitors (AIs). Five broad strategies were considered for identification and recruitment of women at high risk for breast cancer: 1) in-person recruitment during routine screening mammography with survey administration for breast cancer risk assessment according to the Gail model; 2) collection of breast cancer risk factors from the electronic health record (EHR) for risk assessment according to the Breast Cancer Surveillance Consortium (BCSC) risk calculator; 3) identification of women with atypical hyperplasia (AH) or lobular carcinoma in situ (LCIS) using ICD-9/10 diagnostic codes from the EHR; 4) high-risk women with clinic appointments and referred by enrolled providers; 5) women who responded to recruitment flyers and online recruitment distributed throughout the medical center and community. Results: A total of 6229 high-risk women were identified using these recruitment sources, of which 3663 were contacted by email, mailed letter, and/or phone for participation in our clinical trial. Of these contacted women, 16.4% were identified through in-person recruitment during screening mammography, 35.8% through breast cancer risk factors in the EHR, 14.5% had a diagnosis of AH or LCIS identified in the EHR, 28.7% had appointments with enrolled providers, and 4.5% responded to recruitment flyers or online recruitment. Women from the different recruitment sources varied by mean age (64.7 years for mammography and 44.9 years for recruitment flyers), race/ethnicity (73.7% non-white from mammography and 45.5% from breast cancer risk factors in the EHR), and mean 5-year breast cancer risk (2.56% identified from the EHR and 1.34% from recruitment flyers). Of 300 consented patients, 44.7% came from provider referrals (12.7% recruitment yield [number consented/number contacted]) and 27.3% from mammography (13.6% recruitment yield). Comparing enrolled to unenrolled patients, there were significant differences in mean age (57.3 vs. 58.7 years, p=0.027), proportion of non-whites (41.5% vs. 54.7%, p&amp;lt;0.001), and mean 5-year breast cancer risk (3.0% vs. 2.2%, p&amp;lt;0.001). Conclusions: We were able to identify a large cohort of women at high risk from breast cancer from multiple different recruitment sources. Our recruitment yield was highest among direct referrals from healthcare providers and in-person recruitment from mammography. Consented patients tended to be younger, include more non-Hispanic whites, and have a higher risk of breast cancer compared to the overall pool of high-risk women identified. We were able to successfully recruit a racially-ethnically diverse study population to a randomized controlled trial of decision support for breast cancer chemoprevention.

Design of the Arizona CoVHORT: A Population-Based COVID-19 Cohort.

This study is a prospective, population-based cohort of individuals with a history of SARS-CoV-2 infection and those without past infection through multiple recruitment sources. The main study goal is to track health status over time, within the diverse populations of Arizona and to identify the long-term consequences of COVID-19 on health and well-being. A total of 2,881 study participants (16.2% with a confirmed SARS-CoV-2 infection) have been enrolled as of December 22, 2020, with a target enrollment of 10,000 participants and a planned follow-up of at least 2 years. This manuscript describes a scalable study design that utilizes a wide range of recruitment sources, leveraging electronic data collection to capture and link longitudinal participant data on the current and emerging issues associated with the COVID-19 pandemic. The cohort is built within a collaborative infrastructure that includes new and established partnerships with multiple stakeholders, including the state's public universities, local health departments, tribes, and tribal organizations. Challenges remain for ensuring recruitment of diverse participants and participant retention, although the electronic data management system and timing of participant contact can help to mitigate these problems.
