Buying and selling price for risky lotteries and expected utility theory with gambling wealth

I analyze two expected utility models which abandon the consequentialist assumption of terminal wealth positions. In the expected utility of gambling wealth model, in which initial wealth is allowed to be small, I show that a large WTA/WTP gap is possible and the (Rabin in Econometrica, 68(5), 1281–1292, 2000) paradox may be resolved. Within the same model the classical preference reversal which allows arbitrage is not possible, whereas preference reversal (involving buying prices in place of selling prices), which does not allow arbitrage, is possible. In the expected utility of wealth changes model, in which there is no initial wealth, I show that both a WTA/WTP gap as well as the classical preference reversal are possible due to loss aversion, both in its general as well as some specific forms.
Job strain in nursing homes—Exploring the impact of leadership

AIMS AND OBJECTIVES To explore the association between nursing home managers' leadership, job strain and social support as perceived by direct care staff in nursing homes. BACKGROUND It is well known that aged care staff experience high levels of job strain, and that aged care staff experiencing job strain are exposed to increased risk for adverse health effects. Leadership styles have been associated with job strain in the literature; however, the impact of perceived leadership on staff job strain and social support has not been clarified within nursing home contexts. DESIGN This study had a cross-sectional design. METHODS Participating staff (n = 3,605) completed surveys which included questions about staff characteristics, valid and reliable measures of nursing home managers' leadership, perceived job strain and social support. Statistical analyses of correlations and multiple regression analysis with interaction terms were conducted. RESULTS Nursing home managers' leadership were significantly associated with lower level of job strain and higher level of social support among direct care staff. A multiple regression analysis including an interaction term indicated individual and joint effects of nursing home managers' leadership and social support on job strain. CONCLUSIONS Nursing home managers' leadership and social support were both individually and in combination associated with staff perception of lesser job strain. Thus, nursing home managers' leadership are beneficial for the working situation and strain of staff. RELEVANCE TO CLINICAL PRACTICE Promoting a supporting work environment through leadership is an important implication for nursing home managers as it can influence staff perception of job strain and social support within the unit. By providing leadership, offering support and strategies towards a healthy work environment, nursing home managers can buffer adverse health effects among staff.
Why Do Managers Voluntarily Issue Cash Flow Forecasts?

We study a relatively recent change in voluntary disclosure practices by management, namely, the issuance of cash flow forecasts. We predict and find that management issues cash flow forecasts to signal good news in cash flow, to meet investor demand for cash flow information, and to precommit to a certain composition of earnings in terms of cash flow versus accruals, thus reducing the degree of freedom in earnings management. Our results also suggest that management discloses good news in cash flow to mitigate the negative impact of bad news in earnings, to lend credibility to good news in earnings, and to signal economic viability when the firm is young. Our finding that management cash flow forecasts primarily convey good news is in contrast to the generally negative nature of management earnings guidance and suggests that different incentives drive firms' disclosure of different financial information.
Invasive Sphenoidal Aspergillosis: Successful Treatment with Sphenoidotomy and Voriconazole

Treatment of invasive sphenoidal aspergillosis is surgical, followed by antifungal therapy, mostly amphotericin B. To optimize the adjuvant antifungal treatment, which is often limited by severe side effects, the new triazole antifungal agent voriconazole with broad coverage of fungal pathogens including Aspergillus was investigated in a study of 4 patients with clinical, radiological and histological signs of invasive sphenoidal aspergillosis. They first underwent endoscopic sphenoidotomy with drainage and extraction of the fungal mass. Postoperatively, 2 patients were immediately treated with voriconazole. Two patients initially received amphotericin B; but this treatment had to be stopped because of acute renal toxicity. Finally, all patients were treated orally with 200 mg voriconazole twice a day for 12–14 weeks. After this combined treatment all patients were asymptomatic and there were no endoscopic or radiological signs of residual fungal disease. The only side effects were nausea in one and transient visual disturbances in 2 other patients. In the 4 patients presented and treated, voriconazole was shown to be effective and less toxic than amphotericin B in adjuvant treatment of invasive sphenoidal aspergillosis.
The Efficacy of Sustainability Values in Predicting Travelers’ Choices for Sustainable Hospitality Businesses

Sustainability studies suggest that travelers’ decisions to support sustainable production and to consume sustainable hospitality and tourism services are functions of those travelers’ values. This study examined the efficacy of the sustainability value (SV) scale in predicting potential travelers’ choices for sustainable hospitality businesses using a partially mediated structural equation model. Data from a panel of 1,202 recent travelers in North America suggest that SVs predict an individual’s choice for sustainable hospitality businesses. The effect of those values, however, is partially mediated by the travelers’ environmental behaviors. Based on the respondents’ attitudes and behavior, they were grouped into an environment-supporting group called “strong-sustainers” and an environment-neutral group termed “centrists-sustainers. ” Extending these findings to the market, hoteliers could offer targeted sustainability messages for the proposed “strong-sustainer” traveler, who would be more likely to purchase a “green” room, and likewise customize communications to the “centrist-sustainer” travelers, for whom an environmental message carries no weight.
Stereotactic thalamotomy in tremor‐dominant Parkinson's disease: An H215O PET motor activation study

Stereotactic thalamotomy is an effective treatment for severe drug‐resistant tremor. The thalamus, however, facilitates motor activiry, and thalamotomy would be predicted to inhibit movement‐associated cortical activation. Two tremulous parkinsonian patients were studied with H2 15O position emission tomography before and after left ventalis intermedius thalamotomy. Subjects were scanned at rest and during performance of externally paced joystick movements in freely selected direstions with the right hand. Thalamotomy relieved tremor but, as perdicted, led to dercreased activation of the left sensorimotor cortex, lateral premotor cortex, and parietal area 7 on hand movement.
Credibility for the 21st Century: Integrating Perspectives on Source, Message, and Media Credibility in the Contemporary Media Environment

Technological capabilities and features of the Internet and World Wide Web have prompted concerns about the verity of online information, the credibility of new media, and the new responsibilities placed on media consumers. Reflecting these concerns, scholars have shown a renewed interest in the credibility of sources, their messages, and the media that carry them. Nonetheless, researchers who are currently reengaging the issue of information credibility have yet to take full advantage of the rich heritage left by credibility research conducted over the last half century. The primary aim of this chapter is to show how past research can inform present attempts to understand credibility in the new media environment, focusing particularly on Web-based information. Toward that end, this chapter reviews, synthesizes, and integrates the substantial literature on source, message, and media credibility; addresses issues of credibility conceptualization, operationalization, and measurement; suggests strategies to empower online users and information providers; and culminates with strategies for credibility research and an agenda for the study of credibility in the contemporary media environment.
Instructors' Growth in TPACK: Teaching Technology-Infused Methods Courses to Preservice Teachers

Abstract We were concerned about teaching a stand-alone technology integration course while advocating that teachers employ full integration. Our college moved to a tech-infusion model whereby our educational technology curriculum would be incorporated in methods courses. Using a qualitative approach, we documented experiences of teacher educators who were content experts and were asked to teach a tech-infused course. In comparison to their first time teaching their course, during their third experience they demonstrated that knowledge in teaching teacher candidates how to integrate technology was highly developmental in nature and supported by advancements in instructors' expertise. We found evidence that small changes in their practice were creating larger consequences within our college; it appears our professional development model is creating a positive cultural shift.
Body Image Disturbance, Parental Bonding and Alexithymia in Patients with Eating Disorders

Background: To evaluate if body image disturbance and alexithymia, two major clinical features of eating disorders (ED), are predicted by an altered parental bonding. Sampling and Methods: 64 female ED outpatients and 68 female healthy controls were assessed by means of the Parental Bonding Instrument (PBI), the Body Uneasiness Test (BUT), and the Toronto Alexithymia Scale (TAS-20). Pearson’s correlations and multiple stepwise regression analysis were applied to explore the contribution of PBI factors on BUT and TAS scores. Results: BUT weight phobia, body image concerns, avoidance, depersonalization, Global Severity Index and positive symptom total were predicted by low parental care, while compulsive self-monitoring was predicted by parental overprotection. TAS total score and difficulty in describing feelings were predicted by low maternal care. Conclusions: Body image disturbance in ED may be conceptualized as a deficit in self-development, resulting from failures in parent-child interactions which impaired the ability to distinguish bodily needs from emotional experiences.
New analyses of the National Institute of Mental Health Treatment of Depression Collaborative Research Program: Do different treatments reflect different processes?

Abstract To determine whether or not different therapies have distinct patterns of change, it is useful to investigate not only the end result of psychotherapy (outcome) but also the processes by which outcomes are attained. The present study subjected data from the National Institute of Mental Health Treatment of Depression Collaborative Research Program to survival analyses to examine whether the process of psychotherapy, as conceptualized by the phase model, differed between psychotherapy treatment approaches. Few differences in terms of progression through phases of psychotherapy were identified between cognitive behavior therapy and interpersonal therapy. Additionally, results indicate that phases of psychotherapy may not represent discrete, sequentially invariant processes.
Seasonality in tourism employment: human resource challenges

Seasonality in tourism has a profound impact on the management of human resources in organizations operating in a seasonal context. Tourism employment in Canada is profiled and its seasonality examined in Atlantic Canada, where seasonal tourism employment is common. A model for managing seasonality in employment is proposed as a continuum, ranging from “embracing” to “challenging” seasonality. For each approach, differing human resource management practices are identified and operational impacts are discussed, providing possible strategies for employers operating in seasonal tourism contexts. Ongoing research is planned in Atlantic Canada’s accommodations sector, testing the model for managing seasonal tourism employment.
Nisoldipine Cardioplegia in the Isolated Rabbit Heart

Background: The metabolic and hemodynamic effects of nisoldipine supplementation in cardioplegia after ischemic injury were investigated in 13 isolated rabbit hearts. Group 1 con sisted of 6 hearts, which received St. Thomas II cardioplegic solution. In group 2, nisoldipine was added to the cardioplegic solution at a concentration of 0.1 mg/kg in 7 hearts. Methods: The explanted hearts were suspended from Langendorff apparatus and were per fused with Krebs-Henseleit solution. Left ventricular pressure, heart rate, malondialdehyde, glutathione peroxidase, glutathione reductase, reduced glutathione, oxidized glutathione, cre atine kinase MB, (CK-MB), aspartate transaminase, and lactate dehydrogenase (LDH) were measured before and after 60 minutes of ischemia. Peak generated pressure after ischemia was significantly higher in group 2 versus group I while end-diastolic pressure was signifi cantly lower in group 2 after ischemic arrest (P < .05). Results: Malondialdehyde levels were lower in group 2 (P < .05). Glutathione peroxidase and glutathione reductase levels were significantly higher in group 2 ( P < .05). The only enzymatic significant difference was observed between the preischemic and postischemic levels of aspartate transaminase in group 2 (P < .05). Conclusions: These findings show beneficial effects of nisoldipine cardioplegia, although its use as a cardioplegic additive is not yet possible. We believe, however, the effects of oral nisoldipine before cardiac surgery can be studied in a clinical setting.
Colonization of mice by Candida albicans is promoted by chemically induced colitis and augments inflammatory responses through galectin-3.

BACKGROUND Little is known about the relationship between colonic inflammation and Candida albicans colonization. Galectin-3 (Gal-3) is an intestinal lectin that binds to specific C. albicans glycans and is involved in inflammation. METHODS Colitis was experimentally induced in wild-type and Gal3(-/-) mice using dextran sulfate sodium (DSS) before oral administration of C. albicans. Yeast recovered from stools was quantified. The presence of yeast and inflammation were evaluated in sections of colon by histologic examination, quantification of myeloperoxidase (MPO) activity, and by gene expression for cytokines and innate immune receptors. Serum from mice was collected for determination of anti-yeast mannan antibodies, including anti-Saccharomyces cerevisiae antibodies (ASCA), which are biomarkers of an inflammatory bowel disease. RESULTS Inflammation strongly promoted C. albicans colonization. Conversely, C. albicans augmented inflammation induced by DSS, as assessed by histologic scores, MPO activity, and tumor necrosis factor (TNF)-alpha and Toll-like receptor (TLR)-2 expression. C. albicans colonization generated ASCA. The absence of Gal-3 reduced DSS inflammation and abolished the response of TLR-2 and TNF-alpha to C. albicans colonization. CONCLUSIONS DSS-induced colitis provides a model for establishing C. albicans colonization in mice. This model reveals that C. albicans augments inflammation and confirms the role of Gal-3 in both inflammation and the control of host responses to C. albicans.
An Assessment of Alternative Structural Models of Philanthropic Behavior

In this article, the question of whether differences in four structural models of charitable behavior make any difference to the findings regarding the major determinants of philanthropic contributions is addressed. Using data from Independent Sector’s Giving and Volunteering Survey, giving and volunteering equations using the standard Tobit model, the “Heckit” model, the Cragg model with uncorrelated errors, and the Cragg model with correlated errors are estimated. Results indicate that the generalized two-stage approaches are far superior to the standard Tobit model for both monetary donations and volunteer time. For monetary giving, parameter estimates of the second-stage contribution equations are similar across the three alternative two-stage methods and there is no evidence of correlation between the first- and second-stage error terms. Second-stage estimates for volunteering from the Heckit and Cragg models with correlated errors are also similar and offer compelling evidence of correlated error terms.
Using Celebrity Candidates in Political Marketing Campaigns

Celebrity candidature is a novel application of the celebrity endorsement practice to the field of political marketing. Modern politics is no stranger to the use of celebrities as spokespeople, endorsers and supports of causes, candidates and campaigns. This paper argues that the new high-water mark for celebrity endorsement of political marketing campaigns is the celebrity turned political candidate. Using the case of Peter Garrett (media celebrity, musician, political activist and ALP member for Kingsford Smith), the paper proposes a multipart model of celebrity political marketing for further investigation
Coping with food poverty in cities: The case of urban agriculture in Glen Norah Township in Harare

Abstract The focus of this study is on urban agriculture which is a common informal sector activity across most sub-Saharan African cities. Urban agriculture is more common among poor urban households, and acts as a poverty coping mechanism. Poor households often spend more than 60% of their income on food alone. The major thrust of this study was to understand the underlying mechanisms driving farming in cities. A mixed method research approach was adopted and data was collected from 103 households in Glen Norah Township in Harare, Zimbabwe through semi-structured interviews, questionnaires and observations. Arising from analysis of the data, the Urban Livelihoods Coping Model (ULCM) is proposed in order to explain the phenomenon of urban agriculture in African cities. This model acknowledges the fact that the socio-economic conditions and the socio-historical context of Zimbabwe and other African countries today is as a result of the influence of ‘Western leaning’ development policies influenced by modernization and associated theories. These theories combined with cultural factors and the impact of Structural Adjustment Policies resulted in the present situation where urban agriculture plays a critical role in the survival of the urban poor as a coping mechanism against food poverty. The ULCM ascribes the emergence of urban agriculture to necessity, ability and opportunity. The significance of this study is that it will contribute to understanding the socio-economic role of urban agriculture and how it can be factored into the urban planning systems of developing countries.
Serum lipid profiling of patients with chronic hepatitis B, cirrhosis, and hepatocellular carcinoma by ultra fast LC/IT‐TOF MS

In this study, an ultra fast LC/IT‐TOF MS (UFLC/IT‐TOF MS)‐based serum lipidomics method was employed to characterize the serum lipid profile of patients with chronic hepatitis B, cirrhosis, and hepatocellular carcinoma (HCC). After data collection and processing, 96 lipids including lysophosphatidylcholines, phosphatidylcholines, sphingomyelins, triacylglycerides, and cholesterol esters were identified and used for subsequent data analysis. Partial least squares‐discriminant analysis revealed that patients with liver diseases had distinctly different serum lipid profile from that of healthy controls; while cirrhosis and HCC patients had a similar serum lipid profile, but different from that of hepatitis patients. The ANOVA analysis found 75 of the 96 identified lipids to be abnormally regulated, among which most of these lipids were downregulated in cirrhosis and HCC patients compared with those of healthy controls and hepatitis patients, while hepatitis patients induced several lipids downregulated and others upregulated compared with those of healthy controls, indicating the aberrant lipid metabolism in patients with liver diseases. This work demonstrated the utility of UFLC/IT‐TOF MS‐based serum lipidomics as a powerful tool to investigate the lipid metabolism of liver diseases.
Stock Returns, Dividend Yields, and Taxes

Using an improved measure of a common stock's annualized dividend yield, we document that risk-adjusted NYSE stock returns increase in dividend yield during the period from 1963 to 1994. This relation between return and yield is robust to various specifications of multifactor asset pricing models that incorporate the Fama-French factors. The magnitude of the yield effect is too large to be explained by a "tax penalty" on dividend income and is not explained by previously documented anomalies. Interestingly, the effect is primarily driven by smaller market capitalization stocks and zero-yield stocks. Copyright The American Finance Association 1998.
Corporate Cross-Holdings of Equity, Leverage and Pensions: Simulation and Empirical Evidence from the UK

This article examines the role of defined benefit company pensions in amplifying the effect of common shocks to companies' stock market valuations. It identifies and evaluates the significance of two channels of amplification: cross-holdings of equities in pension scheme assets and leverage induced by pension liabilities. Econometric analysis of weekly stock market data for a sample of FTSE 350 UK companies confirm that these effects are statistically significant and robust to outlying observations.

The Abundance of Cell Cycle Regulatory Protein Cdc4p Is Controlled by Interactions between Its F Box and Skp1p

ABSTRACT Posttranslational modification of a protein by ubiquitin usually results in rapid degradation of the ubiquitinated protein by the proteasome. The transfer of ubiquitin to substrate is a multistep process. Cdc4p is a component of a ubiquitin ligase that tethers the ubiquitin-conjugating enzyme Cdc34p to its substrates. Among the domains of Cdc4p that are crucial for function are the F-box, which links Cdc4p to Cdc53p through Skp1p, and the WD-40 repeats, which are required for binding the substrate for Cdc34p. In addition to Cdc4p, other F-box proteins, including Grr1p and Met30p, may similarly act together with Cdc53p and Skp1p to function as ubiquitin ligase complexes. Because the relative abundance of these complexes, known collectively as SCFs, is important for cell viability, we have sought evidence of mechanisms that modulate F-box protein regulation. Here we demonstrate that the abundance of Cdc4p is subject to control by a peptide segment that we term the R-motif (for “reduced abundance”). Furthermore, we show that binding of Skp1p to the F-box of Cdc4p inhibits R-motif-dependent degradation of Cdc4p. These results suggest a general model for control of SCF activities.
