Abstract In this literature review, we overview some of the common management practices associated with calf rearing in specialized operations of the United States. Given the growing importance of dairy-beef calves entering the beef production of the US, we overview aspects related to housing, nutrition, and health events during the pre- and post-weaning period. Based on data on dairy animals, we hypothesize how early life experiences could impact the feedlot performances of dairy-beef animals. Most of the large calf raising operations, where the majority of dairy-beef animals are raised, are located in the Central Great Plains and West regions of the US. Approximately 80% of calves are individually housed, but the type of housing (e.g., outside hutch, inside a barn) varies based on location of calf-raising facilities. Milk-replacer is fed in more than 80% of operations, while milk (saleable or non-saleable) is fed in approximately 30% of calf raising facilities (some operations fed more than one type of liquid diet). In addition to liquid feed, water and calf starter are offered ad libitum to calves. Adequate starter intake at weaning is crucial for feed transition from pre- to post-weaning period, which occurs at approximately 2 months of age. Then, calves are mainly housed in group pens and transition from calf-starter to total mixed ration (TMR). Health challenges such as scours, and bovine respiratory disease (BRD) can hinder the performance of calves and are major causes of morbidity and mortality in calf ranches. Transportation at a very young age and comingling with animals from other dairies can increase the risk of diseases. Current research efforts are focusing on determining individual factors such as body weight (BW) at arrival or biomarkers of inflammation and stress that can be predictive of disease morbidity, mortality, and performance of calves. Future research should focus on how to utilize this information to optimize management and to develop targeted preventative strategies to reduce incidence of diseases and mortality and improve performance during the pre-weaned period. Also, more research is needed to understand how colostrum management, housing, and nutrition can impact the adult performance of dairy-beef animals.

Summary: In the United States' normative population for the WAIS-R, differences (Ds) between persons' verbal and performance IQs (VIQs and PIQs) tend to increase with an increase in full scale IQs (FSIQs). This suggests that norm-referenced interpretations of Ds should take FSIQs into account. Two new graphs are presented to facilitate this type of interpretation. One of these graphs estimates the mean of absolute values of D (called typical D) at each FSIQ level of the US normative population. The other graph estimates the absolute value of D that is exceeded only 5% of the time (called abnormal D) at each FSIQ level of this population. A graph for the identification of conventional “statistically significant Ds” (also called “reliable Ds”) is also presented. A reliable D is defined in the context of classical true score theory as an absolute D that is unlikely (p < .05) to be exceeded by a person whose true VIQ and PIQ are equal. As conventionally defined reliable Ds do not depend on the FSIQ. The graphs of typical and abnormal Ds are based on quadratic models of the relation of sizes of Ds to FSIQs. These models are generalizations of models described in Hsu (1996) . The new graphical method of identifying Abnormal Ds is compared to the conventional Payne-Jones method of identifying these Ds. Implications of the three juxtaposed graphs for the interpretation of VIQ-PIQ differences are discussed.

The prevalence of diet-induced obesity and type-2 diabetes remains a growing concern in the United States. As best management practices still include improved diet and physical activity, bioactive food components, contained within functional foods, show promise in curbing the cardiometabolic complications associated with excess weight and diabetes. Quinoa is an emerging candidate crop for its versatility in wide-ranging growing conditions as one approach to address food security, but it also contains several components that may serve as a dietary tool for post-industrial countries struggling with the health complications of caloric excess. Preliminary rodent feeding studies demonstrate that components within quinoa, namely, phytosteroids, phenolics, polysaccharides, and peptides, can prevent adiposity, dyslipidemia, and hyperglycemia. Mechanistic activity may involve reduced lipid absorption and adipogenesis, increased energy expenditure and glucose oxidation and corrected gut microbiota. Other intestinal actions may include blocked carbohydrate digestion with enhanced incretin signaling. Evidence in clinical trials is lacking and future research spanning cells to the clinic is needed to further elucidate the interesting preliminary reports reviewed here. Quinoa offers several unique attributes that could be harnessed to improve the dietary management of obesity and diabetes.

Western Great Plains

In agricultural settings, environment shapes patterns of settlement and land use. Using the Great Plains of the United States during the period of its initial Euro-American settlement (1880–1940) as an analytic lens, this article explores whether the same environmental factors that determine settlement timing and land use—those that indicate suitability for crop-based agriculture—also shape initial family formation, resulting in fewer and smaller families in areas that are more conducive to livestock raising than to cropping. The connection between family size and agricultural land availability is now well known, but the role of the environment has not previously been explicitly tested. Descriptive analysis offers initial support for a distinctive pattern of family formation in the western Great Plains, where precipitation is too low to support intensive cropping. However, multivariate analysis using county-level data at 10-year intervals offers only partial support to the hypothesis that environmental characteristics produce these differences. Rather, this analysis has found that the region was also subject to the same long-term social and demographic changes sweeping the rest of the country during this period.

Abstract. Carbon fixed by agricultural crops in the US creates regional CO2 sinks where it is harvested and regional CO2 sources where it is released back to the atmosphere. The quantity and location of these fluxes differ depending on the annual supply and demand of crop commodities. Data on the harvest of crop biomass, storage, import and export, and on the use of biomass for food, feed, fiber, and fuel were compiled to estimate an annual crop carbon budget for 2000 to 2008. With respect to US Farm Resource Regions, net sources of CO2 associated with the consumption of crop commodities occurred in the Eastern Uplands, Southern Seaboard, and Fruitful Rim regions. Net sinks associated with the production of crop commodities occurred in the Heartland, Northern Great Plains, and Mississippi Portal regions. The national crop carbon budget was balanced to within 0.3 to 6.1 % yr−1 during the period of this analysis.

Elemental sulfur is commonly applied for powdery mildew (Erysiphe necator) protection on winegrape (Vitis sp.). The product may be used in a diversified, integrated disease management system to help prevent fungicide resistance to products with other modes of action. Additionally, sulfur may be used as a control option in organic systems. Applications of sulfur have been known to cause phytotoxic injury to susceptible winegrape cultivars, particularly those stemming from fox grape (Vitis labrusca) parentage. To improve recommendations to producers in the northern Great Plains region of the United States, a comparison of injury incidence and severity, as well as effects on yield characteristics was undertaken for 13 regional cultivars exposed to three sulfur rates (0, 2.4, and 4.8 lb/acre a.i.) at a North Dakota State University Research Station near Absaraka, ND. Overall, four cultivars (Bluebell, Baltica, Sabrevois, and King of the North) of the 13 cultivars tested showed phytotoxic symptoms. Injury severity and incidence of these cultivars differed between years and across rates. ‘Bluebell’ showed consistent and severe sulfur injury symptoms. Injury to the other three susceptible cultivars tended to vary by the given environment, with King of the North generally showing the lowest injury response. Injury symptoms were not found to be associated with the overall yield or cluster weight. Results suggest that alternative spray programs that exclude sulfur-based fungicides should be recommended for ‘Bluebell’, ‘Baltica’, ‘Sabrevois’, and ‘King of the North’, whereas sulfur-based fungicides may be applied to ‘Alpenglow’, ‘ES 12-6-18’, ‘Frontenac’, ‘Frontenac Gris’, ‘La Crescent’, ‘Marquette’, ‘Somerset Seedless’, ‘St. Croix’, and ‘Valiant’. Observations on fruit ripening in 2014 suggest that future research is needed to determine if a reduction of fruit quality may occur in some seasons with repeated sulfur applications or with successive annual sulfur applications for susceptible cultivars if used in an organic production system.

Bicultural Stress

This chapter discusses the concepts of acculturative and bicultural stress, the theory and method behind the measurement, and the implications of the US immigration policy context for stress. The central sources of acculturative and bicultural stress are reviewed, including intergroup discrimination, language stress, intragroup marginalization, and family cultural conflict. In particular, literature is reviewed that examines the association between mental health and acculturative or bicultural stress. Extant research does demonstrate that degree of stress varies for individuals and that acculturative/bicultural stress is experienced not only by immigrants but also by minorities in the United States. Therefore, the present chapter reviews literature that connects the acculturative/bicultural stress process across generations. The immigration context is considered for future research in the area of acculturation and stress.

Federal Judges

The increased polarization in the United States among the political branches and citizenry affects the selection, work, perception, and relative power of state and federal judges, including justices of the US Supreme Court. Polarization in the United States over the last few decades matters to the American judicial system in at least four ways. First, polarization affects judicial selection, whether the selection method is (sometimes partisan-based) elections or appointment by political actors. In times of greater polarization, governors and presidents who nominate judges, legislators who confirm judges, and voters who vote on judicial candidates are more apt to support or oppose judges on the basis of partisan affiliation or cues. Second, driven in part by selection mechanisms, polarization may be reflected in the decisions that judges make, especially on issues that divide people politically, such as abortion, guns, or affirmative action. The Supreme Court, for example, often divides along party and ideological lines in the most prominent and highly contested cases. Those ideological lines now overlap with party as we enter a period in which all the Court liberals have been appointed by Democratic presidents and all the Court conservatives have been appointed by Republican presidents. Third, increasingly polarized judicial decisions appear to be causing the public to view judges and judicial decision making (at least on the US Supreme Court) through a more partisan lens. Fourth, polarization may affect the separation of powers, by empowering courts against polarized legislative bodies sometimes paralyzed by gridlock. The review concludes by considering how increased polarization may interact with the judiciary and judicial branch going forward and by suggesting areas for future research.

The purpose of this study was to explre the relationship between total quality management and firm performance, i.e. quality, business and organizational performance in Jordanian private airlines. The design of this study has a quantitative approach. Data was obtained by questionnaire instrument. The respondents of this study are all employees in quality department, maintenance department, human resource department, and operation department. The number of population was 480 employees. Random sampling was used in the study. 340 completed questionnaires were analyzed as a final sample. Three hypotheses have been developed through literature review and tested using descriptive statistical analysis performed by SPSS. The results show that total quality management practices have a positive and significant impact on business, quality, and organizational performance in Jordanian private airlines. The study reports that effective implementation of total quality management practices results in enhancing airline performance. The major limitation of this study is that the study asked for perceived data about actual TQM practices and performance measures, but the respondents might have given desired data, which made their companies sound good, most of the respondents were non managers and from different departments in addition to the quality department, who might not understand to answer the questions accurately. Another limitation was that business performance tenets were measured by using one question per each tenet. Future research may investigate those TQM practices and performance measures in another Jordanian industry.

Purpose This paper aims to present an analysis of the perception of performance management practices and transformations by investigating what devolved governments of Kenya are doing and ought to do after which the approaches of performance and performance management are evaluated. Design/methodology/approach A descriptive assessment of five devolved governments of Kenya is carried out. This study covered 518 respondents across the above-sampled governments. Findings The outcomes demonstrated that there are guidelines established by the counties to measure the performance of workers where tested variables about setting performance standards and performance review information against their effect on performance improvement and performance measurement, respectively, are statistically significant, and therefore have a positive impact on the eventual performance of devolved governments. Practical implications The results support scholars, practitioners and social scientists in development studies for the planning and management of public organizations. The thought of factors that enhance or impede devolved government workers’ performance can be explored in future research. Originality/value The thought of performance management perception, especially in a developing country, is a theoretical milestone.

Abstract The coronavirus public health crisis is also a political-communication and health-communication crisis. In this article, the authors describe the key communication-related phenomena and evidence of concerning effects manifested in the United States during the initial response to the pandemic. The authors outline the conditions of communication about coronavirus that contribute to deleterious outcomes, including partisan cueing, conflicting science, downplayed threats, emotional arousal, fragmented media, and Trump's messaging. The authors suggest these have contributed to divergent responses by media sources, partisan leaders, and the public alike, leading to different attitudes and beliefs as well as varying protective actions taken by members of the public to reduce their risk. In turn, these divergent communication phenomena will likely amplify geographic variation in and inequities with COVID-19 disease outcomes. The authors conclude with some suggestions for future research, particularly surrounding communication about health inequity and strategies for reducing partisan divergence in views of public health issues in the future.
