Managing the Slot Operations of a Hotel Casino in the Las Vegas Locals’ Market

This exploratory study was designed to identify and explain the sources of variation in the daily slot handle of a locals’ market hotel casino in Las Vegas, Nevada. A regression model was used to analyze the effects of temporal, operational, and marketing variables hypothesized to influence slot handle. A simultaneous regression analysis was conducted with audited, secondary data using variables adapted from prior research. Significance tests were conducted at the . 05 alpha level. The model failed to produce a significant effect for the food covers variable. The buy-in incentives (direct mail) and bingo headcount variables were significantly and positively related to slot handle. The temporal variables emerged as powerful predictors of slot handle. Finally, the results demonstrate the questionable economic significance of the buy-in incentives program and the bingo operation.

Engineering Structurally Configurable Models with Model Transformation

Abstract : Complex configurable models of embedded software systems are hard to design and maintain, especially when model structures are variable and the number of allowable configurations is unlimited. We employ model transformation as an underlying technique to configure model structures. A transformation tool is created for actor models that automates tasks in the development workflow. Such tasks include structural configuration with user-specified parameters, resetting enhanced models to simple forms for modification and update, and validating consistency in model structures. As an example, we provide a structurally configurable actor-oriented model of a distributed system using the MapReduce pattern to justify our approach.
Co-Constructing Inquiry-based Science with Teachers: Essential Research for Lasting Reform.

In this article we assert a potential research agenda for the teaching and learning of science as inquiry as part of the JRST series on reform in science education. Drawing on the theoretical frameworks of cognitive and sociocultural constructivism, cultural models of meaning, the dialogic function of language, and transformational models of teacher education, we propose that more research is needed in the areas of teachers' beliefs, knowledge, and practices of inquiry-based science, as well as, student learning. Because the efficacy of reform efforts rest largely with teachers, their voices need to be included in the design and implementation of inquiry-based curriculum. As we review the literature and pose future research questions, we propose that particular attention be paid to research on inquiry in diverse classrooms, and to modes of inquiry-based instruction that are designed by teachers. fl 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 631 - 645, 2001 Today's reform rhetoric has revived the concept of inquiry as representing the essence of science education. Reform documents such as the National Science Education Standards are promoting inquiry as the ''central strategy for teaching science. '' The editors of the Journal of Research in Science Teaching have encouraged dialogue on the efficacy of programs, such as inquiry-based science, that are being initiated or implemented in our schools. The editors state, ''this reform effort represents unfinished business for the science education community. Despite the seeming efficacy of the goals and claims that underlie current reform, there has been little formal, scholarly effort on the part of the science education community to ground the reform carefully in research. '' As part of a series of articles in JRST that explore the relationship between research and reform, this article discusses the need for research on the topic of inquiry. The purpose of this article is to propose a direction for future research on inquiry that places teacher knowledge, actions, and meanings for inquiry-based science at the center of the reform process. The proposal of a research agenda for inquiry approaches that are centered on teacher beliefs and knowledge may accelerate the production of a research literature that bridges the theory - practice gap in this important area. In this article, we present the position that additional
Is Oligopoly a Condition of Successful Privatization? The Case of Cotton in Zimbabwe

Zimbabwe embarked on market liberalization in the early 1990s, leading towards increasing participation of private capital in the agricultural sector. This paper examines the emergent shape of the private marketing chain for cotton in Zimbabwe, based on fieldwork conducted in the 1999-2001 cotton marketing seasons. The privatization of the cotton marketing board replaced state monopoly with private oligopoly and competition is still seriously underdeveloped, especially on price. However, because of a concentrated market and collective private action, important aspects of earlier systems of coordination have been maintained, preventing downgrading of Zimbabwean cotton lint after liberalization. The paper concludes with a discussion about (absence of) competition and commodity system sustainability in liberalized markets.
Effect of processing methods for transmission electron microscopy on corneal collagen fibrils diameter and spacing

Introduction: The corneal tissue was processed in fixatives and embedded in resin for transmission electron microscopy to observe the ultrastructure of the collagen fibrils (CFs). The effect of these processing methods on the CF diameter and the interfibrillar spacing was studied. Methods: Four normal human corneal buttons were used for this study. A part of each cornea was fixed in 2.5% glutaraldehyde containing cuprolinic blue in sodium acetate buffer and embedded in spurr's resin (SpurrCB). A second part of each cornea was fixed in 2.5% glutaraldehyde + osmium tetroxide and embedded spurr's resin (SpurrOsm). The third part of each cornea was fixed in paraformaldehyde (4%) and embedded in LR White at 4°C (LRWhite). Ultrathin sections were stained with uranyl acetate and lead citrate. Results: In the tissue, fixed in SpurrCB, the diameter was 38.4 ± 5.9 nm and spacing between CF was 52.5 ± 5.3 nm. In the tissue fixed in SpurrOsm, the diameter was 28.37 ± 5.84 nm and spacing between CF was 45 ± 4.57 nm. In the tissue fixed in LR White, the CF diameter was 24 ± 2.3 nm and spacing between CF was 39.0 ± 4.2 nm. The diameters and interfibrillar spacing of the tissue processed by SpurrCB, SpurrOsm, and LRWhite were significantly different (P < 0.001) from one another. Conclusion: Our study shows that there is a variation in the CF diameter and spacing depending on the method of fixation and embedding resins used. This needs to be considered when comparative studies using different methods are done. Microsc. Res. Tech. 2012. © 2012 Wiley Periodicals, Inc.
Species-specific audio detection: a comparison of three template-based detection algorithms using random forests

8 We developed a web-based cloud-hosted system that allow users to archive, listen, visualize, and annotate recordings. The system also provides tools to convert these annotations into datasets that can be used to train a computer to detect the presence or absence of a species. The algorithm used by the system was selected after comparing the accuracy and efficiency of three variants of a template-based detection. The algorithm computes a similarity vector by comparing a template of a species call with time increments across the spectrogram. Statistical features are extracted from this vector and used as input for a Random Forest classifier that predicts presence or absence of the species in the recording. The fastest algorithm variant had the highest average accuracy and specificity; therefore, it was implemented in the ARBIMON web-based system. 9
Jordan’s e-Government at the crossroads

Purpose – The purpose of this paper is to assess the maturity level of the Jordanian electronic Government (e-Government) program from the citizen’s perspective. This assessment aims to help in determining whether the Jordanian e-Government strategy, set back in 2002, has achieved its main objectives which are delivering services to people across society, irrespective of location, economic status, education or ICT ability; improving the ICT readiness and infrastructure; and developing new service delivery channels and increase the involvement of citizens through the use of ICTs. Jordan started a national e-Government initiative aiming to streamline government procedures and provide government information and services to the public online. This paper reveals the levels of citizens’ awareness, acceptance, usage and willingness to use the e-Government services in Jordan. It investigates issues such as Jordan’s e-Government maturity level, citizen’s preferences when dealing with e-Government, citizen’s attitu.
Papillary thyroid microcarcinomas: a comparative study of the characteristics and risk factors at presentation in two cancer registries.

CONTEXT Papillary thyroid microcarcinoma (PTMC) is an indolent neoplasia, often asymptomatic and discovered incidentally. Some PTMCs, however, exhibit a more aggressive behavior, frequently recur, and can even cause cancer-related death. OBJECTIVE The aim of this study was to evaluate the prevalence of PTMCs and the associated risk factors at presentation in 2 thyroid cancer registries from areas with different genetic and environmental characteristics. DESIGN AND PATIENTS We conducted a retrospective, observational study of all incident cases of PTMCs recorded over a 5-year period in the Sicilian Regional Registry for Thyroid Cancer (SRRTC) and in the Surveillance Epidemiology and End Results (SEER) US registry. SETTING The study took place at an academic hospital. RESULTS The incidence of PTMCs was much higher in Sicily (1777 PTMC diagnosed in 2002-2006; age-standardized incidence rate for the world population [ASRw] = 5.8 per 100 000) than in the United States (14 423 PTMC in the period 2004-2008; ASRw = 2.9 per 100 000). Within the SRRTC, a significantly higher incidence was observed in the volcanic area (ASRw = 10.4 vs 4.6 in the rest of Sicily). In Sicily, the female to male ratio was higher, and PTMC patients were younger. In both registries, a significant inverse correlation was observed between age and tumor size. Young patients (≤45 y) exhibited a higher frequency of nodal metastases. CONCLUSIONS PTMC incidence is twice as high in Sicily compared with the United States, and within Sicily, the incidence is twice as high in the volcanic area. In young patients, PTMCs are larger at presentation and exhibit more risk factors. In both registries, more than 35% of PTMCs exhibited 2 or more risk factors, suggesting that they may require surgery and follow-up similar to that of larger carcinomas.
Understanding the role parents play in tennis success: a national survey of junior tennis coaches

Objectives: To assess coaches’ perceptions about the role of parents and their positive and negative behaviours in junior tennis. Methods: A national survey of 132 United States junior tennis coaches was completed. The extent and seriousness/impact of parent-child interaction problems and positive behaviours were rated. Results: Parents were perceived as very important for junior tennis success. Most parents (59%) that these coaches had worked with were seen as having a positive influence on their player’s development. However, the respondents also felt that 36% of parents negatively influenced their child’s development. Positive parental behaviours included providing logistical, financial, and social-emotional support, as well as tennis opportunities and unconditional love. Negative parent behaviours included overemphasising winning, holding unrealistic expectations, and criticising their child. Conclusions: Findings are discussed relative to current sport parenting and athletic talent development research and theorising. The need to educate parents is emphasised.
Liquidity and Asset Market Dynamics

We study economies with an essential role for liquid assets in transactions. The model can generate multiple stationary equilibria, across which asset prices, market participation, capitalization, output and welfare are positively related. It can also generate a variety of nonstationary equilibria, even when fundamentals are deterministic and time invariant, including periodic, chaotic, and stochastic (sunspot) equilibria with recurrent market crashes. Some equilibria have asset price trajectories that resemble bubbles growing and bursting. We also analyze endogenous private and public liquidity provision. Sometimes it is efficient to have enough liquid assets to satiate demand; other times it is not.

Decreased sensitivity to metocurine during long-term phenytoin therapy may be attributable to protein binding and acetylcholine receptor changes.

Long-term phenytoin therapy induces resistance to the neuromuscular blocking effects of metocurine. The hypothesis that this is attributable to increased plasma protein binding of the drug (decreased free fraction) related to increased concentrations of alpha 1-acid glycoprotein (AAG) or attributable to the proliferation of acetylcholine receptors (AChR) at the muscle membrane was tested in the rat. After 14 days of phenytoin 40 mg.kg-1, administered intraperitoneally twice daily (n = 12), the neuromuscular pharmacodynamics were evaluated and compared with those of time-matched controls (n = 10). Protein binding was measured by equilibrium dialysis, AAG concentrations by radial immunodiffusion assay, and AChR by 125I-alpha-bungarotoxin binding. The effective dose for 50% inhibition of baseline twitch height (ED50) was significantly greater in the phenytoin group than in the control group (15.03 +/- 1.65 micrograms.kg-1 vs. 9.98 +/- 0.69 micrograms.kg-1, respectively). The concentrations of AAG increased gradually from 133.8 +/- 7.8 micrograms.ml-1 at day 0, to 343.1 +/- 58.0 micrograms.ml-1 at day 7, to 1,729.5 +/- 422.3 micrograms.ml-1 at day 14 in the phenytoin group. The induction of AAG concentrations in plasma was dependent on plasma phenytoin concentrations and was most prominent after 14 days of phenytoin (r = 0.77; P less than 0.01; n = 22). The free fraction of metocurine was significantly decreased in the phenytoin group compared to the control group (67.2 +/- 0.18% vs. 74.5 +/- 2.5%). There was a significant negative correlation between increased AAG concentrations and decreased free fraction (r = 0.65). (ABSTRACT TRUNCATED AT 250 WORDS)
Events, Public Discourses and Responsive Government: Quality Assurance in Health Care in England, Sweden and Japan

One would expect the common agenda of improving the quality of care in hospital sectors across nations to bring about a convergence of their quality assurance systems. However, one finds great variations in the ways in which such schemes are constructed and communicated to the general public in different countries. This paper examines three universal health care systems (England, Sweden and Japan) and explores the degree to which political institutions and public opinions affect the processes of quality assurance system building within them. It argues that the inputs from governments in response to public concerns are the key to understanding the changes in this seemingly profession-dominated policy domain; therefore policy changes are significantly affected by dynamic interactions between events, public discourses and governance structures within these countries. The findings also demonstrate that public access to information has begun to have a large impact on policy debates in all three countries.
Prospective evaluation of Pringle maneuver in hepatectomy for liver tumors by a randomized study.

OBJECTIVE To evaluate whether vascular inflow occlusion by the Pringle maneuver during hepatectomy can be safe and effective in reducing blood loss. SUMMARY BACKGROUND DATA Hepatectomy can be performed with a low mortality rate, but massive hemorrhage during surgery remains a potentially lethal problem. The Pringle maneuver is traditionally used during hepatectomy to reduce blood loss, but there is a potential harmful effect on the metabolic function of hepatocytes. There has been no prospective randomized study to determine whether the Pringle maneuver can decrease blood loss during hepatectomy, improve outcome, or affect the metabolism of hepatocytes. METHODS From July 1995 to February 1997, we studied 100 consecutive patients who underwent hepatectomy for liver tumors. The patients were randomly assigned to liver transection under intermittent Pringle maneuver of 20 minutes and a 5-minute clamp-free interval (n = 50), or liver transection without the Pringle maneuver (n = 50). The surface area of liver transection was measured and blood loss during transection per square centimeter of transection area was calculated. Routine liver biochemistry, arterial ketone body ratio (AKBR), and the indocyanine green (ICG) clearance test were done. RESULTS The two groups were comparable in terms of preoperative liver function and in the proportion of patients having major hepatectomy. The Pringle maneuver resulted in less blood loss per square centimeter of transection area (12 mL/cm2 vs. 22 mL/cm2, p = 0.0001), a shorter transection time per square centimeter of transection area (2 min/cm2 vs. 2.8 min/cm2, p = 0.016), a significantly higher AKBR in the first 2 hours after hepatectomy, lower serum bilirubin levels in the early postoperative period, and, in cirrhotic patients, higher serum transferrin levels on postoperative days 1 and 8. The complication rate, the hospital mortality rate, and the ICG retention at 15 minutes on postoperative day 8 were equal for the two groups. CONCLUSION Performing the Pringle maneuver during liver transection resulted in less blood loss and better preservation of liver function in the early postoperative period. This is probably because there was less hemodynamic disturbance induced by the bleeding.
3-Hydroxyl-3-methylglutaryl Coenzyme A (HMG-CoA) Reductase Inhibitor (Statin)-induced 28-kDa Interleukin-1β Interferes with Mature IL-1β Signaling*

Background: HMG-CoA reductase inhibitors (statins) have anti-inflammatory effects, the molecular mechanisms of which remain unclear. Results: Statin treatment of macrophages induces secretion of a 28-kDa form of IL-1β that interferes with mature IL-1β signaling. Conclusion: Statins may dampen inflammation through induction of an anti-inflammatory form of IL-1β. Significance: These observations may provide clues toward elucidating the in vivo anti-inflammatory effects of statins. Multiple clinical trials have shown that the 3-hydroxyl-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors known as statins have anti-inflammatory effects. However, the underlying molecular mechanism remains unclear. The proinflammatory cytokine interleukin-1β (IL-1β) is synthesized as a non-active precursor. The 31-kDa pro-IL-1β is processed into the 17-kDa active form by caspase-1-activating inflammasomes. Here, we report a novel signaling pathway induced by statins, which leads to processing of pro-IL-1β into an intermediate 28-kDa form. This statin-induced IL-1β processing is independent of caspase-1- activating inflammasomes. The 28-kDa form of IL-1β cannot activate interleukin-1 receptor-1 (IL1R1) to signal inflammatory responses. Instead, it interferes with mature IL-1β signaling through IL-1R1 and therefore may dampen inflammatory responses initiated by mature IL-1β. These results may provide new clues to explain the anti-inflammatory effects of statins.
Private equity, the minimalist organization and the quality of employment relations

This article develops a firm-level analysis of how the quality of employment relations following acquisition by private equity firms (PEFs) is contingent upon the strategic intent of those firms and the post-acquisition organizational choices they make. The efficiency gains that PEFs seek in acquired companies are expected to encourage restructuring towards a minimalist organization. However, the form such an organization takes is seen to depend on whether PEF strategy is oriented primarily towards extracting short-term value from acquired assets rather than towards renewing and developing those assets. Contrasts in the process of restructuring and in organizational form associated with these two strategies will have different implications for the quality of employment relations. The way in which PEFs restructure the companies or units they acquire is the key intervening factor between the strategic intent of PEFs and impact they have on the quality of employment relations.
A possible deficiency of cell-mediated immunity in the opossum, Trichosurus vulpecula, in relation to tuberculosis.

Abstract Extract The Australian opossum, Trichosurus vulpecula, is susceptible to experimental infection with both human and bovine strains of Mycobacterium tuberculosis (Bollinger and Bollinger, 1948). Naturally occurring infections of M. bovis have been reported in opossums in New Zealand (Ekdahl et al., 1970). Smith (1972) has described the lesions seen in such infections as being generalized, suppurative and associated with sinus formation and has mentioned the epidemiological significance of the disease in these animals.
Role of Wet Experiment Design in Data Generation: From in Vivo to in Silico and Back

A thorough understanding of the in vivo kinetics of microorganisms requires the analysis of different data sets and therefore needs support from different sources of genome, transcriptome, proteome and metabolome data, as well as to generate new data in the laboratory to depict cell phenotypes in different scenarios. The value of dynamic metabolic data depends on the adequate design of wet experiments. In this paper a schematic representation of wet dynamic experiments to generate data is discussed. As a case study, the linking of the central metabolism with the carnitine secondary metabolism in E. coli is presented. The feed-back between the data generated and in silico modeling helps our understanding of the Escherichia coli expressed phenotype and permits new wet experiments to be designed to generate data concerning metabolic optimization.
The distribution of blood flow in the carotid and vertebral arteries during dynamic exercise in humans

Non‐technical summary The mechanism underlying the plateau or relative decrease in cerebral blood flow during maximal incremental dynamic exercise remains unclear. We show that during graded dynamic exercise, the regulation of internal carotid artery blood flow was limited by a large increase in external carotid artery blood flow, one function of which is thermoregulation during heavy exercise. The mechanism of the plateau or decrease in internal carotid artery blood flow appears to be partly due to exercise‐induced redistribution of arterial blood flow to the head and brain.
