In this paper we incorporate a linear demand function to model the price-volume causal relationship into stochastic cost-volume-profit (CVP) analysis. We assume that the objective function is to maximize expected profit; other objective functions are also discussed and compared. A linear stochastic model follows from which probabilistic statements can be easily obtained if the random variables are assumed to be multivariate normal. The basic framework is shown to be a special case of project value maximization where project value is the cash flow of the project discounted for time and risk according to the capital asset pricing model. Moreover, an intertemporal extension that considers inventory is developed. In summary, a new approach to stochastic CVP analysis that incorporates the management decision process in an uncertain environment is developed. 相似文献

Young adulthood is a period renowned for engagement in impulsive and risky behaviors, including gambling. There are some indications
that young adults exhibit higher gambling rates in comparison to older adults. Problem gambling has also been linked to ADHD.
This longitudinal study examines the relationship between gambling and ADHD among an epidemiological sample of young adults
(n = 235; males = 179, females = 56) aged 18-24. Results indicate that individuals who report childhood ADHD symptoms which
persist into young adulthood experience greater gambling problem severity than participants with no ADHD or those with non-persistent
ADHD. 相似文献

One medical specialty classification system applicable for research and career counseling is the person‐oriented versus technique‐oriented taxonomy. Given that the model was conceptualized in the 1960s, verification based on how medical specialties are practiced and viewed today is necessary. Five specialists in medical career development and advising verified the categorization of specialties. Based on their review, 100% consensus was reached regarding grouping of specialties. This outcome validates the taxonomy of medical specialties and supports its continued use for medical career specialty advising and choice. 相似文献

This case-study adopts a mixed research methodology in order to evaluate the process and the effectiveness of a psychodynamically informed training seminar for field supervisors of undergraduate social work students, at a South European University. At the beginning of the seminar, an anonymous questionnaire gathered information on the supervisors’ demographics, preferred supervision style and expectations from the training. The training consisted of four sessions involving analysis of (1) student process-recorded interviews with clients, (2) the relationships formed between the student, the supervisor and the field practice manager, (3) brief virtual scenarios (vignettes) of field practice problems and (4) a videotaped supervision session. At the end of the training process, a follow-up questionnaire researched the satisfaction of supervisors with the training, their confidence to conduct supervision, and their satisfaction with the instructor's teaching. Overall, the training has been satisfactory for the trainees and increased their competence to supervise. 相似文献

In recent years, treatments of family violence have tended to be built around conventional discourses suggesting that men are major initiators in instances of interpersonal violence. Utilizing a postmodernist analysis, we assess societal discourses that continue to give life to this narrow conceptualization of interpersonal violence. We also examine literature suggesting that both men and women resort to violence to resolve relationship difficulties and suggest that a more holistic and inclusive approach to understanding interpersonal violence is critical for social workers committed to social justice and a balanced understanding of the contextual nature of human problems. 相似文献

Abstract The International Wellbeing Index (IWI), a global measure for investigating subjective wellbeing, consists of a Personal Wellbeing Index (PWI) and a National Wellbeing Index (NWI). The index is applied to the two largest ethnic populations in New Zealand—New Zealanders with European heritage and New Zealanders with Maori heritage. Psychometric characteristics of the IWI for both subsamples compare favourably to those found in other countries. However, for both subsamples, the absolute value of reported subjective wellbeing is lower than expected. Consistent with other social indicators, New Zealanders with Maori heritage show even lower values of PWI and NWI than New Zealanders with European heritage. 相似文献

The initial version (v1) of the Fish Invasiveness Scoring Kit (FISK) was adapted from the Weed Risk Assessment of Pheloung, Williams, and Halloy to assess the potential invasiveness of nonnative freshwater fishes in the United Kingdom. Published applications of FISK v1 have been primarily in temperate‐zone countries (Belgium, Belarus, and Japan), so the specificity of this screening tool to that climatic zone was not noted until attempts were made to apply it in peninsular Florida. To remedy this shortcoming, the questions and guidance notes of FISK v1 were reviewed and revised to improve clarity and extend its applicability to broader climatic regions, resulting in changes to 36 of the 49 questions. In addition, upgrades were made to the software architecture of FISK to improve overall computational speed as well as graphical user interface flexibility and friendliness. We demonstrate the process of screening a fish species using FISK v2 in a realistic management scenario by assessing the Barcoo grunter Scortum barcoo (Terapontidae), a species whose management concerns are related to its potential use for aquaponics in Florida. The FISK v2 screening of Barcoo grunter placed the species into the lower range of medium risk (score = 5), suggesting it is a permissible species for use in Florida under current nonnative species regulations. Screening of the Barcoo grunter illustrates the usefulness of FISK v2 as a proactive tool serving to inform risk management decisions, but the low level of confidence associated with the assessment highlighted a dearth of critical information on this species. 相似文献
