This paper presents stories from women who work and care for a child with a significant chronic illness or disability. The purpose of this paper is to move towards ending the silence on their lives. A three-phase emergent research design responds to the question: What is life like for a full-time worker who is concurrently the primary carer of a chronically ill child? This paper considers the theory of Silencing the Self (Jack, 1991) in relation to the emergent themes of “Otherness” and “Doing it All.” As in Jack’s study, these women also engaged in silencing of the self. However, unlike the respondents in Jack’s study, these women did not demonstrate feelings of worthlessness and hopelessness for the future, nor were they alone in contributing to their silence. Indeed, many experienced silencing behaviors from others around them, and many rallied against the silence, not accepting that their burden should continue. Consideration of Jack’s theory is made to point out the distinctions between the women in this study and Jack’s study, and analytical commentary is provided to demonstrate the relevance of this analysis in light of the current debates surrounding the Work–Home Conflict and the rising levels of informal care provided by women in our communities.  相似文献

We extend the whistle-blowing literature to the context of wrongful firings that violate a public policy. Our results suggest that the incidence of wrongful firings varies, depending on the employee’s gender and tenure, and the industry in which the organization operates. Wrongful firings do not occur more frequently in certain occupations, since firms wrongfully discharge professional and managerial employees as often as employees in technical, clerical, and laborer occupations. We also show that gender, tenure, occupation, and industry, in combination, can distinguish between three types of wrongful firings in violation of public policy. Our results support the application of theory and empirical research on whistle-blowing to the wrongful firing context, aiding researchers interested in developing explanations of wrongful firings in violation of public policy. For managers, our study points to the need to develop more effective responses to employees exercising legal rights, refusing to participate in illegal or unethical activities, and performing a public duty or obligation, such as whistle-blowing.  相似文献

This study examines how (in)congruence regarding the format of the ad and the context in which the ad is placed influences ad recognition, perceived advertiser sensitivity, ad comprehension, and persuasion. Highly visual or informational ads were placed congruently or incongruently within a(n) highly visual or informational surrounding context. There was some positive support for mismatching the format of the ad and surrounding context in terms of ad recognition. Specifically, a highly visual ad placed within a highly informational setting resulted in the greatest ad recognition. However, in terms of the audience's perceptions of advertiser sensitivity, subjective ad comprehension, and ad persuasion, there was more positive support for matching the format of the ad with that of the surrounding context. In this regard, it is better to place visual ads congruently within visual contexts. Theories from information processing and hemispheric lateralization are drawn on to support this research.  相似文献

Accounting accreditation standards place a strong emphasis on student engagement in the learning process (1 and 14). However, budget constraints at many universities are creating larger class sizes, thereby complicating the student-engagement process in two respects. First, it is difficult for professors to motivate students to prepare for class when the students perceive a small probability of being held individually accountable for reading assigned materials. Second, it becomes harder for professors to have one-on-one interactions with students during class as enrollments grow (Litke, 1995). This lack of interaction makes it more difficult to engage students in the learning process. This article describes a teaching approach, called the “hot seat,” that overcomes these challenges by motivating students to prepare for class and engage in the learning process during class. Assessment data suggest that students valued the instructor’s commitment to high-quality instruction and that they believed the hot-seat approach accomplished its intended objectives of increasing student preparation, participation, and learning.  相似文献

The ability of banks to offer proprietary mutual funds has expanded over recent years, and the mutual fund industry has been a significant growth area for banks. I examine the growth and performance of bank proprietary bond mutual funds. The empirical results show no evidence that bank‐managed mutual funds underperform nonbank funds. I find some evidence that bank managers are more conservative than nonbank managers in terms of investment strategy and that banks appear more likely to target individual rather than institutional investors. Also, I find that abnormal fund performance does not appear to be a significant determinant of the net asset flows into and out of bank‐managed mutual funds. Rather, the results suggest bank investors rely mainly on past marketing information and the general reputation of the bank. JEL classification: G11, G21  相似文献

Material selection in the chemistry value chain involves consideration of many objectives, including cost, performance, health risk, and environmental impact. Alternatives assessment is an emerging tool for guiding complex decisions with respect to these goals. As a relatively new method, the process is not yet well developed, especially with respect to how trade‐offs among objectives can be assessed accurately and inexpensively. Using paint strippers alternatives assessment as an illustrative example, we show how an established decision‐analytic method, known as comparative screening, allows for a multistep process with gradually increasing information needs. Compared with existing methodological approaches, comparative screening instills flexible and consistent treatment of trade‐offs. This is important because it maximizes the potential for a robust assessment while minimizing arduous data collection. Further, its use in the alternatives assessment process can support the selection of more sustainable materials.  相似文献

This paper looks at some of the ethical concerns regarding a recent application to the U.S. Food and Drug Administration (FDA) for approval of the sale of HIV tests over-the-counter (OTC) directly to consumers. The concept of at-home HIV testing is not new, but OraSure Technologies Inc., a U.S. manufacturer of rapid HIV tests, is now seeking FDA approval to take at-home testing one step further to enable consumers to test themselves and interpret the results without the assistance of an outside party. This paper reviews some of the purported benefits and potential risks of at-home HIV testing, and looks at the way one Canadian company is attempting to address the potential risks. In doing so, this paper brings to the fore concerns regarding corporate involvement in the regulatory approval of biotech products.  相似文献

Objectives:

To estimate the clinical and economic trade-offs involved in using a molecular assay (92-gene assay, CancerTYPE ID) to aid in identifying the primary site of difficult-to-diagnose metastatic cancers and to explore whether the 92-gene assay can be used to standardize the diagnostic process and costs for clinicians, patients, and payers.

Methods:

Four decision-analytic models were developed to project the lifetime clinical and economic impact of incorporating the 92-gene assay compared with standard care alone. For each model, total and incremental costs, life-years, quality-adjusted life-years (QALYs), incremental cost–effectiveness ratios (ICERs), and the proportion of patients treated correctly versus incorrectly were projected from the payer perspective. Model inputs were based on published literature, analyses of SEER (Surveillance Epidemiology and End Results) data, publicly available data, and interviews with clinical experts.

Results:

In all four models, the 92-gene assay increased the proportion of patients treated correctly, decreased the proportion of patients treated with empiric therapy, and increased quality-adjusted survival. In the primary model, the ICER was $50,273/QALY; thus, the 92-gene assay is therefore cost effective when considering a societal willingness-to-pay threshold of $100,000/QALY. These findings were robust across sensitivity analyses.

Conclusions:

Use of the 92-gene assay for diagnosing metastatic tumors of uncertain origin is associated with reduced misdiagnoses, increased survival, and improved quality of life. Incorporating the assay into current practice is a cost-effective approach to standardizing diagnostic methods while improving patient care. Limitations of this analysis are the lack of data availability and resulting modeling simplifications, although sensitivity analyses showed these to not be key drivers of results.  相似文献

We examine whether firms utilize governance systems and increased monitoring mechanisms when information asymmetry and managerial discretion are limited. Given that such monitoring is costly, we expect regulated firms to use less monitoring if regulation substitutes for governance. Using data from initial public offerings, we document that regulated firms have greater proportions of monitoring directors and larger boards as well as use similar amounts of equity-based compensation as non-regulated firms. Further, regulated and unregulated firms are analogous in terms of observed trade-offs between traditional monitoring mechanisms and insider ownership. Finally, regulated firms appear to decrease monitoring following a period of deregulation. These findings support the hypothesis that regulation and governance are complements and are consistent with the notion that regulators pressure firms to adopt effective monitoring structures.  相似文献
