Paul Smith 《Industrial Relations Journal》2019,50(5-6):431-449
In the 1950s, given the scope of the Trade Disputes Act 1906 that had granted immunity against specific torts (civil wrongs) to organisers of industrial action, the courts had little role in industrial relations. Hence, the importance of the House of Lords decision in 1964 that, in threatening to strike to secure Douglas Rookes's removal from the Heathrow design office of the British Overseas Aircraft Corporation after his resignation from the union, Alfred Barnard and others had used unlawful means because a threat to break a contract of employment came within the tort of intimidation that was unprotected by the Trade Disputes Act's statutory immunities, and thus, they were liable to pay damages to Rookes. The legal arguments deployed are analysed within growing unease in the Conservative Party and among employers at the emergence of workplace union organisation and national strikes. Despite being partially neutralised by the Trade Disputes Act 1965, Rookes was a harbinger of a new judicial activism that outflanked trade unions' tort immunities by creating novel common law liabilities. This in turn laid the political basis for subsequent Conservative legislation to restrict and regulate trade unions and industrial action, a project that is ongoing. 相似文献

A Consumer-Based Approach to Designing Product Line Extensions 总被引:1,自引:0,他引:1
A high proportion of new product introductions entail line extensions (e.g., new flavors, sizes, convenience packs, features) rather than totally new products. An attendant problem with line extending involves the possibility of cannibalization of the firm's current products. Paul Green and Abba Krieger describe an approach for designing line extensions that employs consumer tradeoff data and a variety of search heuristics to find "optimal" extensions that explicitly consider the cannibalization of current offerings. The methodology is applied to a case in which an agricultural chemicals firm is introducing a new soybean herbicide. 相似文献

There is a growing literature on the importance of being first, which suggests that where there is uncertainty about the product quality of late entrants' brands the pioneering brand will retain a competitive advantage. This is consistent with studies of the U.S. drug industry. Using Canadian data for the drug industry it is shown that eliminating quality differences is a necessary but not sufficient condition for late entrants to gain market share. In addition, price competition has to be stimulated. Under these conditions the late entrants have taken up to 100 percent of the pioneering brands market. 相似文献

The industrial marketing as well as the strategic management literature stresses the importance of “value innovation” in order to create/sustain competitive advantage and to rejuvenate the organization.In the first part of this article the construct of value innovation is operationalized within the context of selected business-to-business markets. We report the results of an ongoing research project; starting from traditional ways of value creation, the study reveals different types of value innovation initiatives undertaken by industry participants. We observe, however, that networks, firms and managers are embedded in industry recipes. These recipes block the creation and realization of value innovation. Some firms are trying to break out of existing frames and their experiences pinpoint to specific ways of markets sensing, strategic marketing and different marketing-mix tools. As such, the research frames value innovation initiatives in the existing industry contexts and managerial frames, and identifies drivers, barriers and perceived success factors for the process of value innovation.The second part of the article then looks at the stages of value innovation and their impact on marketing, organizations and networks. Based on the data analysis, the paper posits propositions which stress the concept of “multilevel absorptive capacity”. 相似文献

After more than 50 years of self‐regulation of the US auditing profession, the Sarbanes‐Oxley Act of 2002 (SOX) created the Public Company Accounting Oversight Board (PCAOB) as a quasi‐governmental entity with statutory authority to inspect accounting firms that audit public clients. The frequency of this inspection is annual or triennial, based upon the number of public clients the firm audits. We examine the effects of these two levels of inspection frequency on financial reporting quality and audit fees for clients of small and midsize public accounting firms. Our findings provide evidence of significantly higher audit quality and audit fees for clients of annually inspected firms relative to clients of triennially inspected firms. These findings are robust to auditor‐client alignment analyses, propensity score matching, time‐series analyses, examination of firms that have changed from triennial to annual inspection, and particular examination of firms with inspection deficiencies. Overall, our study suggests that the two‐tier frequency system of PCAOB inspection may have also resulted in two‐tier audit quality and audit fee systems for small and midsize public accounting firms, with more frequent inspection leading to more rigorous and informed auditor decisions. We discuss the implications of our results for the Board and the profession at large. 相似文献

The essays collected in this forum discuss the geopolitical legacy of the Russian Revolution of 1917, one of the most momentous political events of the twentieth century. From a range of different academic disciplines and perspectives, the authors consider how the profound transformations in society and politics were refracted through space and geography, and how enduring these refractions proved to be. The authors focus on three themes that have been dominant in Russian affairs over the past century: 1)the problem of center-periphery relations, 2)the civilizational dynamics of Russia’s self-identification in relation to Europe and to Asia, and 3)the geopolitics of national identity. 相似文献

Objective: To assess long-term healthcare costs related to ischemic stroke and systemic embolism (stroke/SE) and major bleeding (MB) events in patients with non-valvular atrial fibrillation (NVAF) treated with non-vitamin K antagonist oral anticoagulants (NOACs).Materials and methods: Optum’s Clinformatics Data Mart database from 1/2009–12/2016 was analyzed. Adult patients with ≥1 stroke/SE hospitalization (index date) were matched 1:1 to patients without stroke/SE (random index date), based on propensity scores. Patients with an MB event were matched to patients without MB. All patients had an NOAC dispensing overlapping index date, ≥12?months of eligibility pre-index date, and ≥1 NVAF diagnosis. The observation period spanned from the index date until the earliest date of death, switch to warfarin, end of insurance coverage, or end of data availability. Mean costs were evaluated: (1) per-patient-per-year (PPPY) and (2) at 1, 2, 3, and 4?years using Lin's method.Results: The cost differences were, respectively, $48,807 and $28,298 PPPY for NOAC users with stroke/SE (n?=?1,340) and those with MB (n?=?3,774) events compared to controls. Cost differences of patients with vs without stroke/SE were $49,876, $51,627, $57,822, and $60,691 at 1, 2, 3, and 4?years post-index, respectively (p?0.001). These cost differences were $31,292, $35,658, $44,069, and $47,022 for patients with vs without MB after 1, 2, 3, and 4?years post-index, respectively (p?0.001).Limitations: Limitations include unobserved confounders, coding and/or billing inaccuracies, limited sample sizes over longer follow-up, and the under-reporting of mortality for deaths occurring after 2011.Conclusions: The incremental healthcare costs incurred by patients with vs without stroke/SE was nearly twice as high as those of patients with vs without MB. Moreover, each additional year up to 4?years after the first event was associated with an incremental cost for patients with a stroke/SE or MB event compared to those without an event. 相似文献
