An Evolutionary View of the Critical Functions of Slot Machine Technology

The U.S. gaming industry has grown from its infancy in the early 1930s to a maturing giant in the 1990s. With this growth has come an evolution in management functions associated with one of the major components of casino operations, the slot department. These functions; counting, analysis, security, maintenance, and marketing, have evolved through an iterative process of technology; applying science to enhance functionality. This paper traces the expanding applications of gaming technologies, and provides a framework for understanding the past, present and future uses of technology in casino slot operation

The Oswald Clergy Burnout Scale: reliability, factor structure and preliminary application among Australian clergy

This study assesses the Oswald Clergy Burnout Scale (OCBI), the psychometric properties of which have not been previously described. Analysis of responses from a large number (N  = 3,012) of ministers in charge of Australian congregations showed that the scale’s internal reliability was satisfactory, and that the scale could be represented by two factors, identified, respectively, as the personal and social aspects of burnout. This structure was supported by confirmatory factor analysis. Several demographic and job-related variables that might relate to burnout were regressed on the total, personal and social factor scores. Age is the predominant (negative) predictor of burnout as measured by the total scale and the personal factor scores. All variables predict burnout as measured by the social factor. However, in all models, the predictor variables account for no more than 5% of the total variance. These findings suggest that demographic factors and working conditions are poor predictors of burnout among clergy

Perceptions of Public Health 3.0: Concordance Between Public Health Agency Leaders and Employees

CONTEXT AND BACKGROUND: The newest era of public health, deemed "Public Health 3.0," supports cross-sector collaborations to address social determinants of health. These activities often require collaborations with nontraditional public health entities. As this new era begins, it is important to understand perceptions of the public health workforce with regard to Public Health 3.0. OBJECTIVE: To assess perceptions of support toward Public Health 3.0 activities by the public health workforce, identify characteristics associated with support, and measure concordance in support between agency directors and the general workforce. DESIGN: This cross-sectional study utilizes the 2017 Public Health Workforce Interests and Needs Survey to understand support and concordance regarding Public Health 3.0 activities by a nationally representative sample of governmental public health employees. Logistic regression models are used to identify characteristics associated with support of each 3.0 activity and concordance. MAIN OUTCOME MEASURES: Governmental public health employees' opinions on how involved their agency should be in the K-12 education system, the economy, the built environment, transportation, housing, social connectedness, and health equity within their jurisdiction and concordance in support of involvement between agency directors and the general workforce. RESULTS: Overall, individual perceptions supporting involvement were highest for health equity and social connectedness and lowest for transportation. Supervisory status, education, and being at a local health department were associated with greater odds of supporting all 3.0 activities. Concordance with agency directors was greatest among other executives relative to nonsupervisors. CONCLUSIONS: There is overall generally high support of many 3.0 activities, but there are gaps in agreement by supervisory status, gender, race/ethnicity, education, role type, and jurisdiction. Findings may help support agency leaders in better communicating the role of their agencies in Public Health 3.0 activities, and workforce education regarding such activities may be necessary for the success of Public Health 3.0's success

Eating the elephant whole or in slices: views of participants in a smoking cessation intervention trial on multiple behaviour changes as sequential or concurrent tasks

Background: This paper explores smoking cessation participants’ perceptions of attempting weight management alongside smoking cessation within the context of a health improvement intervention implemented in Glasgow, Scotland. <p/>Methods: One hundred and thirty-eight participants were recruited from smoking cessation classes in areas of multiple deprivation in Glasgow and randomised to intervention, receiving dietary advice, or to control groups. The primary outcome of the study was to determine the % change in body weight. Semi-structured interviews were conducted with a purposive sample of 15 intervention and 15 control participants at weeks 6 (during the intervention) and 24 (at the end of the intervention). The current paper, though predominantly qualitative, links perceptions of behaviour modification to % weight change and cessation rates at week 24 thereby enabling a better understanding of the mediators influencing multiple behaviour change. <p/>Results: Our findings suggest that participants who perceive separate behaviour changes as part of a broader approach to a healthier lifestyle, and hence attempt behaviour changes concurrently, may be at comparative advantage in positively achieving dual outcomes. <p/>Conclusions: These findings highlight the need to assess participants’ preference for attempting multiple behaviour changes sequentially or simultaneously in addition to assessing their readiness to change. Further testing of this hypothesis is warranted

Thermal contraints on high-pressure granulite metamorphism of supracrustal rocks

The circumstances leading to the formation and exposure at the Earth's surface of supracrustal granulites are examined. These are defined as sediments, volcanics, and other rock units which originally formed at the surface of the Earth, were metamorphosed to high-pressure granulite facies (T = 700-900 C, P = 5-10 kbar), and reexposed at the Earth's surface, in many cases underlain by normal thicknesses of continental crust (30-40 km). Five possible heating mechanisms to account for granulite metamorphism of supracrustal rocks are discussed: magnetic heating, thermal relaxation of perturbed temperature profiles following underthrusting of the continental crust, thermal relaxation after underthrusting of thin slivers of supracrustal rocks below continental crust of normal thickness, major preheating of the upper plate, and shear heating caused by frictional stress along the thrust plane

The Relationship Between Health Department Accreditation and Workforce Satisfaction, Retention, and Training Needs

BACKGROUND: To improve quality and consistency of health departments, a voluntary accreditation process was developed by the Public Health Accreditation Board. Understanding accreditation's role as a mediator in workforce training needs, satisfaction, and awareness is important for continued improvement for governmental public health. OBJECTIVE: To compare differences in training needs, satisfaction/intent to leave, and awareness of public health concepts for state and local health department staff with regard to their agency's accreditation status. DESIGN: This cross-sectional study considered the association between agency accreditation status and individual perceptions of training needs, satisfaction, intent to leave, and awareness of public health concepts, using 2017 Public Health Workforce Interests and Needs Survey (PH WINS) data. Respondents were categorized on the basis of whether their agencies (at the time of survey) were (1) uninvolved in accreditation, (2) formally involved in accreditation, or (3) accredited. RESULTS: Multivariate logistic regression models found several significant differences, including the following: individuals from involved state agencies were less likely to report having had their training needs assessed; staff from accredited and involved agencies identified more gaps in selected skills; and employees of accredited agencies were more aware of quality improvement. While state employees in accredited and formally involved agencies reported less job satisfaction, there were no significant differences in intent to leave or burnout. Differences were identified concerning awareness of various public health concepts, especially among respondents in state agencies. CONCLUSIONS: While some findings were consistent with past research (eg, link between accreditation and quality improvement), others were not (eg, job satisfaction). Several self-reported skill gaps were unanticipated, given accreditation's emphasis on training. Potentially, as staff are exposed to accreditation topics, they gain more appreciation of skills development needs. Findings suggest opportunities to strengthen workforce development components when revising accreditation measures

Structures of an apo and a binary complex of an evolved archeal b family DNA polymerase capable of synthesising highly cy-dye labelled DNA

Thermophilic DNA polymerases of the polB family are of great importance in biotechnological applications including high-fidelity PCR. Of particular interest is the relative promiscuity of engineered versions of the exo- form of polymerases from the Thermo- and Pyrococcales families towards non-canonical substrates, which enables key advances in Next-generation sequencing. Despite this there is a paucity of structural information to guide further engineering of this group of polymerases. Here we report two structures, of the apo form and of a binary complex of a previously described variant (E10) of Pyrococcus furiosus (Pfu) polymerase with an ability to fully replace dCTP with Cyanine dye-labeled dCTP (Cy3-dCTP or Cy5-dCTP) in PCR and synthesise highly fluorescent “CyDNA” densely decorated with cyanine dye heterocycles. The apo form of Pfu-E10 closely matches reported apo form structures of wild-type Pfu. In contrast, the binary complex (in the replicative state with a duplex DNA oligonucleotide) reveals a closing movement of the thumb domain, increasing the contact surface with the nascent DNA duplex strand. Modelling based on the binary complex suggests how bulky fluorophores may be accommodated during processive synthesis and has aided the identification of residues important for the synthesis of unnatural nucleic acid polymers
