The study reported here compared the influences of psychological constructs (job demands and scheduling control) and objective work characteristics (shiftwork, night‐work and hospital department type) on job satisfaction, organisational commitment, burnout and withdrawal intentions. Our hypothesis was that psychological constructs have a higher influence on work‐related attitudes than objective characteristics of work schedules. In addition to the main effects, we proposed an interactive hypothesis: poor attitudes would result from high demands and low control rather than from other combinations of both psychological variables. Using a sample of 153 hospital nurses in Israel, the hypotheses were generally supported. As night‐work, shiftwork and working in intensive care units are unavoidable characteristics of the modern medical environment, these findings are meaningful for improving the personal adjustment of hospital nurses.  相似文献

Most decision making research in management accounting remains focused on cost information in a production context. Little is known on the relevance of customer profifitability analysis (CuPA) reports, which more accurately reflect revenue and marketing support variations acrosscustomers, for marketing decisions. This study uses an experimental design to examine the impact of such reports on resource allocation decisions (that affect the firm's profits) in marketing environments varying in complexity. The main result of the experiment suggests that the value of CuPA reports depends on the complexity of the marketing setting. Only in a highly complex marketing setting do they enhance resource allocation decisions and resultant firm profitability. Conversely, in the simple marketing environment, decision makers can combine their traditional volume-based cost data with other available types of feedback to perform as well as under a more accurate CuPA report. These findings on complexity contrast with those of a prior study in a production context ( Gupta and King, 1997 ). It is argued that improvements in the current research design, in the form of regularly updated profitability reports and concerning accuracy, increase the relevance of CuPA reports in a complex marketing setting.  相似文献

Summary We consider the problem of making inferences about the parameters of a time series model when there is the possibility of a discrete variance change at an unknown time point. For this we obtain the posterior distributions of the parameters and of the variance ratio.  相似文献

U.S. Labor Law currently allows employers whose work forces are unionized to introduce new technologies without bargaining over the decision to do so. This forces unions to adopt inefficient strategies when negotiating collective bargaining agreements in an effort to minimize the impact of technological change on their members. Allowing unions to bargain over the decision to introduce new technologies would obviate their having to resort to these inefficient strategies. In addition, it might increase the likelihood of employees suggesting alterations in production processes that would increase the rate of technological change. For these reasons, this article advocates amending U.S. labor law to require employers to bargain over the introduction of new technologies.  相似文献

A termination rule based on a critical funding ratio is proposed for a pension guarantee fund (PGF) that considers closing an underfunded pension plan. This ratio is determined by solving an expected utility maximization problem on behalf of plan beneficiaries subject to two constraints designed to preserve the PGF's viability. The first is an upper bound on the PGF's annual intervention probability; the second, a restriction on the expected shortfall of an underfunded pension plan that is not closed. Both too low and too high critical funding ratios hurt beneficiaries’ interests, depending on their degree of risk aversion.  相似文献

We examine the patterns of goodwill impairments in Europe and in the US over the period from 2006 to 2015, for a sample of more than 35,000 firm-year observations. We define the timeliness of goodwill impairments as the frequency of accounting impairments conditional to indications of economic impairments. We measure indications of economic impairment with three metrics: equity market value minus equity book value less than goodwill, market-to-book smaller than one and negative earnings before interest, tax, depreciation and amortisation (EBITDA). Our research strategy leads us to draw very different conclusions than those in the recent EFRAG (2016) study. While median levels of goodwill on the books between US and European firms are relatively similar, we find several indications that US firms recognise timelier impairments, at least during 2008 and 2009, that is, the early years of the financial crisis. We further document that US impairers write down a much greater percentage of their beginning balance of goodwill than European impairers. During the financial crisis, the median level of impairment by US firms was 63% of opening goodwill in 2008 and 40% in 2009, whereas median European write-downs were only 6% and 7% of opening goodwill, respectively. Even though European firms are more likely to impair over multiple years, the cumulative impairments never come close to the level of US firms, be it in a single year or cumulative over multiple years. We also find that the frequency of accounting impairment is small compared to the number of firms presenting evidence of economic impairment: only 20–25% of firms recognise impairments depending on the measure of economic impairment. This has often been interpreted by academics as a sign of untimely write-offs. Accounting differences between US Generally Accepted Accounting Principles and International Financial Reporting Standards are unlikely to explain our results. One caveat of our analysis is that it does not allow us to draw conclusions on whether the observed differences between US and European firms are driven by differences in conditional conservatism and/or big bath accounting practices.  相似文献

This article presents two studies that examine whether leader supportive behaviors facilitate knowledge sharing and employee creative problem‐solving capacity, thereby enhancing creative performance. The findings from both studies indicate that leader supportive behaviors are directly and indirectly related, through both internal and external knowledge sharing, to employee creative problem‐solving capacity. In addition, creative problem solving was related to the two dimensions of creative performance—fluency and originality. However, a test of the mediation model indicated that creative problem solving only mediated the relationship between internal knowledge sharing creative performance and originality. These findings highlight the complex process by which leaders facilitate both internal and external knowledge sharing and employee creative problem‐solving capacity, thereby improving employee creative performance.  相似文献

An effective R&D organization needs information from a complex web of sources, including customers, suppliers, sales and marketing, and company management. Within the R&D organization, information must flow into and among numerous teams. This network of interpersonal communications can go a long way toward determining the success of a company's innovation efforts. In an exploratory study of a Belgian company operating in the telecommunications industry, Rudy K. Moenaert and Filip Caeldries examine the effects of interpersonal communication on market and technological learning in R&D. Trying to improve the flow of information into and within its R&D organization, this company designed its new R&D facility with an eye toward improving both market and technological learning throughout the organization. By locating R&D personnel in closer proximity to one another, management hoped to provide them with improved access to market and technological information, and thus increase their innovativeness. Contrary to expectations, placing R&D professionals in closer proximity to one another did not increase technological learning in this organization. In fact, technological learning actually decreased slightly during the period studied, though the change is not statistically significant. On the other hand, market learning and product innovativeness improved significantly during the period studied. For an R&D professional in this company, members of other R&D teams seem to be more important as sources of market information than as sources of technological information. Surprisingly, the relocation of R&D personnel also did not increase the amount of communication that takes place, either within a project team, between members of different teams, or between R&D professionals and the management steering committee. However, the architectural redesign does appear to have improved the quality of communication. R&D team leaders report that since the relocation, the information flowing into R&D has been more customer focused. This is attributed to the company's ongoing efforts to provide the tools and structures necessary for supporting the objectives of the architectural redesign. For example, implementation of quality function deployment (QFD) has helped innovation team members to focus more clearly on relevant information. The success of the architectural design required approaching this effort as a complex, ongoing process, rather than a quick-fix solution.  相似文献
