This article focuses on the responses of British trade unions to the arrival of Polish workers since the 2004 enlargement of the European Union. It is argued that existing definitions and explanations of UK trade union engagement with migrant workers do not capture the strategies that have been used to engage with these migrant workers. We suggest that there have been two sets of responses. First, recruitment and organization activity has centred on inclusion and has been undertaken on new terrains using innovative strategies. Second, we point to the importance of new linkages locally, regionally, nationally and internationally in organizing these new labour market entrants.  相似文献

Aims: Adverse events (AEs) associated with treatments for metastatic colorectal cancer (mCRC) may compromise the course of treatment, impact quality-of-life, and increase healthcare resource utilization. This study assessed the direct healthcare costs of common AEs among mCRC patients in the US.

Methods: Adult mCRC patients treated with chemotherapy or targeted therapies were identified from administrative claims databases (2009–2014). Up to the first three mCRC treatment episodes per patient were considered and categorized as with or without the AE system/organ category during the episode. Total healthcare costs (2014 USD) were measured by treatment episode and reported on a monthly basis. Treatment episodes with the AE category were matched by treatment type and line of treatment to those without the AE category. Adjusted total cost differences were estimated by comparing costs during treatment episodes with vs without the AE category using multivariate regression models; p-values were estimated with bootstrap.

Results: A total of 4158 patients with ≥1 mCRC treatment episode were included (mean age?=?59 years; 58% male; 60% with liver and 14% with lung metastases; 2,261 [54%] with a second and 1,115 [27%] with a third episode). On average, two treatment episodes were observed per patient with an average length of 166 days per episode. Adjusted monthly total cost difference by AE category included hematologic ($1,480), respiratory ($1,253), endocrine/metabolic ($1,213), central nervous system (CNS; $1,136), and cardiovascular ($1,036; all p?Limitations: Claims do not include information on the cause of AEs, and potentially less severe AEs may not have been reported by the physician when billing the medical service. This study aimed to assess the association between costs and AEs and not the causation of AEs by treatment.

Conclusions: The most costly AEs among mCRC patients were hematologic, followed by respiratory, endocrine/metabolic, CNS, and cardiovascular.  相似文献

This exploratory study examines the early impact of the Unfair Commercial Practices Directive 2005/29/EC on enforcers in Scotland within the context of current policy developments regarding the use of civil and criminal enforcement mechanisms within the UK. The Directive has been implemented in the UK by means of the Consumer Protection from Unfair Trading Regulations 2008 SI 1277 and the duty to enforce the Regulations falls primarily to local authority trading standards services. Twenty-one in-depth interviews were conducted with a range of officers employed within the trading standards service based in eight local authorities in Scotland on their perceptions of the new Regulations. The main findings were that officers’ views of the new Regulations and the civil and criminal enforcement routes available to them was affected by structural, operational, and cultural issues which varied from one authority to another. A number of officers were finding the Regulations a challenge to old ways and there was evidence that many felt unprepared for the Regulations. A number of positive views were expressed regarding the flexibility of the new Regulations and the advantages of the provisions relating to misleading omissions. Overall officers’ experiences of the Regulations were heavily influenced by the complaints received by their particular local authority service.  相似文献

We re-read a foundational work, The Theory of the Growth of the Firm by Edith Penrose, not to identify the androcentric bias but instead to recover a challenge to such bias. Our purpose is to show in Penrose an alternative view of human "nature" and revulsion from "Cartesian" dualisms. At the same time, Penrose had a deep interest in the real world and used metaphor and story alongside empirical observation in the pursuit of theoretical advance. The Theory of the Growth of the Firm provides an approach to industrial organization that is not only consistent with feminist economics but can be read as a methodological and expositional examplar.  相似文献

Compositional data analysis and zeros in micro data   总被引:2,自引:0,他引:2  
The application of compositional data analysis methods in economics has some attraction. The methodology relies upon the use of 'log-ratios' in the statistical analysis. Such an approach is not possible when the data to be analysed include observations where the observed budget share is zero. We, therefore, consider and extend the methods of compositional data analysis in the situation where the data to be analysed include observations where the observed budget share is zero. The modified compositional data methods are discussed both in statistical terms and through potential economic interpretations of the method. Further, the modified methodology is applied to the 1988-89 Australian Household Expenditure Survey yielding estimates for a system of Engel curves.  相似文献

The duration measure of weighted average life has been applied in the capital budgeting literature as a measure of project liquidity. Duration is superior to payback methods because it considers both the timing and present value of the entire cash flow stream. However, the literature is ambivalent on the choice of discount rate in calculating project duration. For duration to properly serve as a project liquidity measure, the internal rate of return should be used to discount future cash flows. Examples show that using the firm's cost of capital to calculate duration fails to measure the time to recover initial project outlays in present value dollars.  相似文献

A broad, dynamic network perspective on solution processes remains scarce. This article presents the process of developing and implementing customer solutions and its effects on the wider business environment by investigating customers and suppliers in the global mining industry (Australia, Chile, and Sweden), analyzing the deployment of a new customer solution, and assessing the changes to the competitive environment and focal firms' relationships with other customers and suppliers. It shows that the forces that drive customer and supplier interests and motivation to co-develop customer solutions may change over time, thus redefining the aim and scope of solutions and creating failure risks. Customers present problems; suppliers respond, on the basis of not only the feasibility of the customer-specific solution but also of their evaluation of future solutions in a broader market; then suppliers aim to standardize successful solutions across markets. Customers want close supplier relationships and unique solutions but also like standardized and repeatable solutions, so they can share development costs with competitors and expose the supplier to competition to avoid lock-in effects. From a network perspective, a novel solution can have a market-shaping effect and evoke reactions from other actors who want to enhance their market position. However, these changes are not necessarily deliberate, and the dynamics that market introductions of solutions trigger may be difficult to predict.  相似文献

This article presents a straightforward and highly participatory methodology for addressing government agencies’ concerns with effective communication strategies for biosecurity when stakeholders are diverse and there is uncertainty about their levels of knowledge. The case study was among peri‐urban landholders in an area where serious animal disease infestation has occurred within the last 10 years. Initially we engaged stakeholders in a consultative process that included establishing a stakeholder influence and interest map for both weeds and animal diseases. This was followed with a mental model approach involving surveys and in‐depth interviews. We elicited information about landholders’ knowledge, practices, values and beliefs regarding biosecurity risk. Our consultative process generated examples that indicate that effective risk communication relies on establishing and affirming mutual levels of trust and credibility between landholders and agencies. While this finding is not surprising, we argue that attention to stakeholder consultative processes is central to overcoming barriers to changing practices and building awareness. Secondly, our data confirmed that while smaller landholders were the initial target for the communication, all landholders represented a similar level of biosecurity risk. Therefore, our approach was critical in overcoming external assumptions about particular actors. Finally, our data pointed to the need to develop a whole of landscape approach to biosecurity risk communication strategy in consultation with local stakeholders.  相似文献
