Industrial hog farming is an increasingly important land use in Mexico. Despite the known public health and environmental risks associated with this factory-style model of production, hog concentrated animal feeding operations (CAFOs) remain unregulated. Legal standards regarding the establishment and operation of swine CAFOs are lacking at municipal, regional, and federal levels. There are currently no restrictions on the size, concentration, or geographic location of operations, and public notice to surrounding and downstream communities is generally not required. These lax environmental standards facilitate swine CAFO expansion in regions such as the Perote Valley, with potential for negative long-term impacts on public health, community well-being, water resources, ecosystems, and climate. 相似文献
Commodity and freight futures contracts are analyzed for their effectiveness in reducing uncertainty for international traders. A theoretical model is developed for a trader exposed to several types of risk. OLS hedge ratio estimation is compared to the SUR and the multivariate GARCH methodologies. Explicit modeling of the time-variation in hedge ratios via the multivariate GARCH methodology, using all derivatives, and taking into account dependencies between prices, results in reductions in risk, even after accounting for transaction costs. Results confirm that while the commodity futures contracts are important for hedging risk, freight futures are a useful mechanism for reducing risk. 相似文献
Literature on consumer ethics tends to focus on issues within the public sphere, such as the environment, and treats other drivers of consumption decisions, such as family, as non-moral concerns. Consequently, an attitude–behaviour gap is viewed as a straightforward failure by consumers to act ethically. We argue that this is based upon a view of consumer behaviour as linear and unproblematic, and an approach to moral reasoning, arising from a stereotypically masculine understanding of morality, which foregrounds abstract principles. By demonstrating the importance of context to consumption decisions and articulating the impact of caring relationships, we highlight how such decisions are both complex and situated. This is particularly evident for decisions involving the needs of others, as occurs in family life. We argue that the incorporation of care ethics provides both theoretical insights and a more complete account of consumer ethics. This is explored empirically through an investigation of the ethical dilemmas arising from consumption decisions made by mothers of young children. Such decisions juxtapose an ethical consumption orientation (representing impartial concerns) with care for one’s child. Therefore, what has been previously considered a failure to act ethically may in fact be the outcome of complex decision making, which involves competing ethical considerations. We discuss the implications of our findings for theory and practice and how this approach to consumer ethics could be applied more widely. 相似文献
There is a long, interdisciplinary tradition of examining why organizations remove privileges from members as a part of disciplinary
action. In contrast, little is known about why organizations return privileges after disciplinary action has occurred. Nonetheless,
such reinstatement is ubiquitous in organizations. This paper provides a starting point for a theory of reinstatement by using
the emerging theoretical domain of relationship repair. Treating reinstatement as relationship repair highlights the importance
of causal attribution, social equilibrium, relationship structure, and power as means of relationship repair. The paper uses
these four bases of relationship repair to develop a series of specific motivations for why managers might reinstate privileges. 相似文献
This paper proposes a theory of competitive agglomeration—a new enquiry into the origins of hierarchical structures and governments.
As a motivating example we analyze the Viking age—the roughly 300 year period beginning in 800 AD—from the perspective of
the economics of conflict. The Viking age is interesting because throughout the time period, the scale of conflict increased—small
scale raiding behaviour eventually evolved into large scale clashes between armies. With this observation in mind, we present
a theoretical model describing the incentives both the defending population and the invading population had to agglomerate
into larger groups to better defend against attacks, and engage in attacks, respectively. We tentatively postulate that competitive
agglomeration during the Viking era was a key impetus to state formation in Europe. 相似文献
We suggest that counterproductive work behaviors can be viewed as a form of protest in which organizational members express dissatisfaction with or attempt to resolve injustice within the organization. Incorporating the three key predictors (injustice, identity and instrumentality, [Klandermans, B., (1997). The social psychology of protest. Oxford: Blackwell.]) from the protest literature leads us to propose that counterproductive behaviors can be both individual and collective. Crossing this dimension with concepts of organizational and individual deviance leads to a fourfold classification of counterproductive work behaviors. 相似文献
In today’s connected economy, interorganizational relationships are increasingly important. Whether government-to-government, political party-to-political party, business-to-business, department-to-department, or some other interorganizational pairing, these relationships can provide organizations with signals used to identify and better respond to changes in their environment and in their interorganizational relationships. This enables astute organizations to not only understand how others will interpret the social signals they send, but also to shape those signals in ways that will improve their interorganizational relationships. We illustrate this herein, using the public and readily recognizable relationships involved with labor relations in the professional sports industry. We show how social signals can explain the way organizations change and adapt to their environments, and how these changes send messages to related organizations. Finally, we provide a set of recommended advice for managers based on this case analysis. 相似文献
Objectives: Complexities in the neuropathic-pain care pathway make the condition difficult to manage and difficult to capture in cost-effectiveness models. The aim of this study is to understand, through a systematic review of previous cost-effectiveness studies, some of the key strengths and limitations in data and modeling practices in neuropathic pain. Thus, the aim is to guide future research and practice to improve resource allocation decisions and encourage continued investment to find novel and effective treatments for patients with neuropathic pain.
Methods: The search strategy was designed to identify peer-reviewed cost-effectiveness evaluations of non-surgical, pharmaceutical therapies for neuropathic pain published since January 2000, accessing five key databases. All identified publications were reviewed and screened according to pre-defined eligibility criteria. Data extraction was designed to reflect key data challenges and approaches to modeling in neuropathic pain and based on published guidelines.
Results: The search strategy identified 20 cost-effectiveness analyses meeting the inclusion criteria, of which 14 had original model structures. Cost-effectiveness modeling in neuropathic pain is established and increasing across multiple jurisdictions; however, amongst these studies, there is substantial variation in modeling approach, and there are common limitations. Capturing the effect of treatments upon health outcomes, particularly health-related quality-of-life, is challenging, and the health effects of multiple lines of ineffective treatment, common for patients with neuropathic pain, have not been consistently or robustly modeled.
Conclusions: To improve future economic modeling in neuropathic pain, further research is suggested into the effect of multiple lines of treatment and treatment failure upon patient outcomes and subsequent treatment effectiveness; the impact of treatment-emergent adverse events upon patient outcomes; and consistent and appropriate pain measures to inform models. The authors further encourage transparent reporting of inputs used to inform cost-effectiveness models, with robust, comprehensive and clear uncertainty analysis and, where feasible, open-source modeling is encouraged. 相似文献
