Empirical research on the geographic distribution of U.S. federal spending shows that small states receive disproportionately more dollars per capita. This evidence, often regarded as the consequence of Senate malapportionment, in reality conflates the effects of state population size with that of state population growth. Analyzing outlays for the period 1978–2002, this study shows that properly controlling for population dynamics provides more reasonable estimates of small‐state advantage and solves a number of puzzling peculiarities of previous research. We also show that states with fast‐growing population loose federal spending to the advantage of slow‐growing ones independently of whether they are large or small. The two population effects vary substantially across spending programs. Small states enjoy some advantage in defense spending, whereas fast‐growing ones are penalized in the allocation of federal grants, particularly those administered by formulas limiting budgetary adjustments. Hence, a large part of the inverse relationship between spending and population appears to be driven by mechanisms of budgetary inertia, which are compatible with incrementalist theories of budget allocation.  相似文献

The main forest transitions that took place in south-central Chile from the end of the last glaciation to the present are reviewed here with the aim of identifying the main climatic and socio-economic drivers of land cover change. The first great transition, driven primarily by global warming, is the postglacial expansion of forests, with human populations from about 15,000 cal. yr. BP, restricted to coastlines and river basins and localized impact of forest fire. Charcoal evidence of fire increased in south-central Chile and in global records from about 12,000 to 6000 cal. yr. BP, which could be attributed at least partly to people. The subsequent expansion of agriculture led to much clearing of forests and the spread of weeds and other indicators of open habitats. The Spanish colonial period in America may have been followed by a transient expansion of forest cover into abandoned land, as indigenous population declined rapidly due to disease and slaughter. The 18th and 19th centuries brought about extensive loss of forests due to the massive impact of lumber extraction for mining operations both in central Chile and in western North America. Two centuries of intensive deforestation, coupled to grazing by cattle and extremely variable rainfall had long-lasting effects on forest cover in south-central Chile, which persist until today. The transition from a preindustrial to an industrial society brought about the “golden age” of timber harvest, assisted by mobile sawmills and railway transportation since the late 1800s. These advances led to the exhaustion of native commercial timber by the late 20th century in south-central Chile. In North America, harvestable stands were exhausted in New England and the Midwest around 1920. Settlement of the independent territories in the late 1800s and early 1900s implied vast burning and clearing of land and mounting soil erosion. Industrial forestry, based on government-subsidized massive plantations of short-rotation exotic trees, developed in the late 20th century, in connection with postindustrial displacement of exploitative activities from developed to third-world nations. In the last two decades, economic globalization and free trade promoted the expansion of new crops and further decline of woodlands, despite modest increases in forest cover. These patterns are repeated in many Latin American countries. To prevent further depletion of native forest resources and to provide an insurance against climate change, in the 21st century developing nations should aim at: (1) relocating subsidies from fiber farms to restoring diverse forest cover, (2) promoting ecosystem management of diverse forest and crops within landscapes, and (3) fostering diverse cultural relationships between people and their land.  相似文献

The authors discuss the consistency of transnational companies in their home, as well as in less developed host countries, concerning ethics, values and social responsibility. Ethical behavior offers good reputation, credibility and tradition to the corporation. It leads to corporate social, environmental and economic responsibilities, cooperating to the desired sustainability. This paper analyzes the inversion of values that corporate governance systems have suffered. The meaning and implication of the corporate social responsibility is investigated and discussed. A “pyramid of values” is built upon individual ethical values at the basis. Over them, the organizational ethical values should indicate the limits of operations, so that the corporate social responsibility can be sustained, in the top. The authors comment that ethical values no longer lead the organization. Its communication with the stakeholders, specifically through reports, has been gradually replacing the code of ethics and corporate values. These reports have taken the basis of the pyramid leading the organizations to socially irresponsible and unethical behavior. They do not guarantee transparency or communicate the needs of the society. It appears that transnational companies do not behave the same way in their home country as they do in host countries, particularly in less developed regions like Latin America and Africa. Lack of communication and transparency may induce employees to unethical decisions and transform the reporting system into a marketing instrument. In order to guarantee compliance with the codes, transparency and ethical responsibility, communication within the organization is essential.  相似文献

This study analyzes real experiences of culture management to better understand how ethics permeates organizations. In addition to reviewing the literature, we used an action-research methodology and conducted semistructured interviews in Spain and in the U.S. to approach the complexity and challenges of fostering a culture in which ethical considerations are a regular part of business discussions and decision making. The consistency of findings suggests patterns of organizational conditions, cultural elements, and opportunities that influence the management of organizational cultures centered on core ethical values. The ethical competencies of leaders and of the workforce also emerged as key factors. We identify three conditions—a sense of responsibility to society, conditions for ethical deliberation, and respect for moral autonomy—coupled with a diverse set of cultural elements that cause ethics to take root in culture when the opportunity arises. Leaders can use this knowledge of the mechanisms by which organizational factors influence ethical pervasiveness to better manage organizational ethics.  相似文献

Whether dealing with debt issues in the Eurozone, investment prospects in emerging markets, or potential disruptions in patterns of global trade, the identification, assessment, and measurement of political risk (PR) are recurring issues for businesses and governments today. In the past few years, abrupt social and political change has become the rule in international relations. A prominent instance of this is the “Arab Spring,” the massive and unexpected wave of social and political turmoil that, starting in the winter of 2010‐2011, swept across the Middle East and North Africa (MENA) region. The Arab Spring has significantly affected the business climate of the countries involved. In doing so, it has also exposed the shortcomings of the extant approaches to PR assessment. This article discusses the performance of five different approaches to PR assessment (OECD, ONDD, EIU, PRS, SACE) vis‐à‐vis the Arab Spring, providing some specific suggestions on how to improve PR assessment and analysis. © 2015 Wiley Periodicals, Inc.  相似文献

Customers’ judgment of corporate responsibility (CR) communication and the effect on confidence and trust as interlinked paradigms are intriguing areas of investigation from both theoretical and empirical perspectives. This research aims to clarify the nature of effective CR communication toward customers by identifying situations of over‐ and undercommunication of CR that might cause misjudgments and therefore lower the level of confidence among customers. The study also provides insights to better explain the link between confidence and trust related to customers’ perceptions of CR communication and compares different judgments and misjudgments regarding the banking industries in Italy and the United Kingdom. The study adopts real and fictitious bank case studies to conduct focus groups investigations of 160 millennial customers’ perceptions of CR communication and how it affects their level of confidence. The findings highlight the role of trust in making independent judgments on CR communications. Some similarities and slight differences in the impact of CR communication on confidence emerge between the countries and greatly depend on the customers’ level of trust in real banks and the influence of the industry effect characterizing the banking sector. This study provides fertile ground for future research into the implementation of a more effective and balanced CR communication strategy to increase customers’ confidence and into the understanding of which communication drivers, apparently independent of CR, affect trust in the long term.  相似文献

Some scholars have emphasized the importance of food tourism in mature and certain emergent economies for growing consumption-related products (e.g., wine, beer, rice, and tea) and attempts have been made to study tourism levers and threats in developing economies. However, to the best of our knowledge, little research has been conducted on the potential development of tourism activities centered on coffee producers and their farms in equatorial countries to determine whether a coffee tourism market is developing in these locales and if this could enhance these countries’ brand perceptions. Thus, this study explores the antecedents of the perceptions, potentialities, attitudes, and behavior of tourists specifically with regard to coffee tourism and coffee cultivation visits. To achieve our goal, we employ a quantitative method involving a survey of potential tourists. Our findings indicate that while the effects of gender and age on the perceptions of coffee cultivation visits are not significant, the effects of coffee consumption and travel in coffee-producing countries are positive and significant. These findings help us draw some relevant theoretical and managerial implications.  相似文献

The aim of the study was to describe classroom Discourses about vegetables during the planning, cooking, eating and evaluation of meals in the Swedish school subject Home and Consumer Studies. Fifty‐nine students and five teachers were recruited from five northern Swedish villages and towns, and then observed, recorded and in some cases video‐taped during lessons that took place between 2010 and 2012. Based on 56 instances of talk about vegetables, four Discourses were identified and related to the three aspects of Belasco's culinary triangle of contradictions: identity, responsibility and convenience. The results indicated that the identity‐based sensory and cultural Discourses sometimes clashed with the more responsibility‐oriented health and evaluation Discourses. The health Discourse was only used when there was an element of evaluation, with assignments connected to grades. In all other cases, the sensory and cultural Discourses guided vegetable use. Sometimes different sensory or cultural assumptions could clash with each other, for example when the teacher insisted on the use of a specific recipe regardless of a student's taste preferences. Since these preferences did not always harmonize with curricular demands for responsibility, there might be a risk of basing grades on aspects of students’ identity. Alternatively, students might feel constrained to argue against their own identity in order to be favourably evaluated. Then again, if teachers always bow to student tastes, this limits their chances of learning about food and physical health. Viewing the dilemma through the lens of the culinary triangle of contradictions may help teachers and researchers develop teaching methods that take all aspects of food choice into account.  相似文献

The aim of this study was to explore how time frames affect pupils and teachers in cooking activities during lessons of different durations for Home and Consumer Studies, with a specific focus on the pupils’ experiences. To investigate this, classroom observations were carried out in 2011 and 2012, with the help of audio and video recordings in three different schools in Sweden and included altogether 22 pupils (18 girls, 4 boys) in grade 9 (15–16 years). Each class was observed during two separate lessons, lasting between 1 h 50 min (110 minutes) and 2 h 20 min (140 min). The six lessons resulted in 12 h of video recorded time and 80 h of sound recordings. The study showed that the importance of finishing on time seemed to be ingrained in most pupils in all classes and the end result was perceived as more important than the process of cooking. The study also showed that knowledge of cooking skills and time management seemed important for success in grade‐related tasks. Pupils demonstrated different ways of handling the time frames, e.g. using various methods to speed up the cooking process. This study raises important questions about the relationship between national and local time frames and the curriculum aims in Home and Consumer Studies.  相似文献
