This article addresses authenticity and how it is selectively used by Civil War reenactors to create credible reenactments. The Civil War provides a structured set of scenarios for reenactors to use as a backdrop for their participation. Some use this backdrop to bring objects to the forefront and others use this setting as a way to interact with an audience person to person. This research indicates that authenticity may come through on different levels for individuals participating in the same activity. An authentic experience or object is authentic because it has an important immediate meaning. The objects and narratives displayed by reenactors may be set in specific history but this does not mean that these same objects and narratives are part of that history. This paper contributes to the study of authenticity by examining groups of Civil War reenactors and where their focus of authenticity lies whether it is on authentic objects or interactions.  相似文献

In recent years, INGO legitimacy has been subject to growing scrutiny from analysts and practitioners alike. Critics have highlighted a backlash against INGOs in the Global South, a growing mismatch between INGO capacities and contemporary global challenges, and diminishing support for norms such as democracy and human rights that underpin INGOs’ work. Although these problems have attracted significant attention within the academic literature, this article argues that existing explorations of INGO legitimacy have broadly conformed either to a top-down approach focused on global norms and institutions or a bottom-up approach focused on the local dynamics surrounding states and populations in the Global South. We suggest that this divide is unhelpful for understanding the current predicament and propose a new approach, which pays closer attention to the interaction between bottom-up and top-down dimensions, and to historical context. This new approach can provide important insights into current debates about the future roles and internal structures of INGOs.  相似文献

Several research articles have documented the disproportionate representation of minorities in school discipline and incarceration settings. In the 2009–2010 school year, research shows nationally 17 percent of African‐American, 8 percent of Native American, and 7 percent Latino American students were suspended at least one time (Losen and Gillespie 2012 ). In addition, studies show African‐American and Latino males represent the largest percentage of inmates in correctional facilities (i.e. jails and prisons) throughout the United States (Sakala 2014 ). While research has documented the relationship between race and the school‐to‐prison pipeline, the relationship between race, intellectual and emotional disabilities, and the school‐to‐prison pipeline has been relatively unexplored. According to Losen and Gillespie ( 2012 ), 25 percent of Black students who were labeled with an intellectual or emotional disability were suspended from school in the 2009–2010 school year compared to 9 percent for White students diagnosed with an intellectual or emotional disability. Furthermore, data show 70 percent of juvenile inmates were diagnosed with learning disabilities and 33 percent were reading below a 4th grade level (Hubner and Wolfson 2001 ). The current review seeks to explore the complex relationship between disability, race, and the school‐to‐prison pipeline to highlight how minority students with special needs are placed on a trajectory towards settings of incarceration.  相似文献

Many social problems can be traced to interpersonal communicationdifficulties, just as many proposed interventions to solve social ills also depend on effective interpersonal communication. This article examines three potential relationships between states of mind and social interaction followed by illustrations from research related to five exemplar social issues—developing effective programs for solving workplace communicationproblems, training the public to detect scams and hoaxes, reducing stereotyping and cross-cultural misunderstanding, managing interpersonal conflict, and constructing effective public health campaigns. We conclude by considering the likely inhibiting and facilitating effects of mindfulness-mindlessness on socially relevant transactions.  相似文献

Recent scandals involving executive leadership have vaulted the topic of executive corruption to a central concern in the organizational literature. History suggests that power can corrupt and that absolute power can be an especially toxic influence. In this paper we propose that the propensity for corruption (as measured by CEO responsibility disposition) of leaders and the degree to which leadership is shared are key factors in understanding the potential for executive corruption. More specifically, shared leadership is proposed as a moderator that can deter corruptive tendencies by providing checks and balances capable of reducing the potential for corrupt behavior. A conceptual model is offered along with propositions to help guide future research and practice.  相似文献

The objectives of this study are to understand tradeoffs between forest carbon and timber values, and evaluate the impact of uncertainty in improved forest management (IFM) carbon offset projects to improve forest management decisions. The study uses probabilistic simulation of uncertainty in financial risk for three management scenarios (clearcutting in 45‐ and 65‐year rotations and no harvest) under three carbon price schemes (historic voluntary market prices, cap and trade, and carbon prices set to equal net present value (NPV) from timber‐oriented management). Uncertainty is modeled for value and amount of carbon credits and wood products, the accuracy of forest growth model forecasts, and four other variables relevant to American Carbon Registry methodology. Calculations use forest inventory data from a 1,740 ha forest in western Washington State, using the Forest Vegetation Simulator (FVS) growth model. Sensitivity analysis shows that FVS model uncertainty contributes more than 70% to overall NPV variance, followed in importance by variability in inventory sample (3–14%), and short‐term prices for timber products (8%), while variability in carbon credit price has little influence (1.1%). At regional average land‐holding costs, a no‐harvest management scenario would become revenue‐positive at a carbon credit break‐point price of $14.17/Mg carbon dioxide equivalent (CO2e). IFM carbon projects are associated with a greater chance of both large payouts and large losses to landowners. These results inform policymakers and forest owners of the carbon credit price necessary for IFM approaches to equal or better the business‐as‐usual strategy, while highlighting the magnitude of financial risk and reward through probabilistic simulation.  相似文献

Leptospirosis is a preeminent zoonotic disease concentrated in tropical areas, and prevalent in both industrialized and rural settings. Dose‐response models were generated from 22 data sets reported in 10 different studies. All of the selected studies used rodent subjects, primarily hamsters, with the predominant endpoint as mortality with the challenge strain administered intraperitoneally. Dose‐response models based on a single evaluation postinfection displayed median lethal dose (LD50) estimates that ranged between 1 and 107 leptospirae depending upon the strain's virulence and the period elapsed since the initial exposure inoculation. Twelve of the 22 data sets measured the number of affected subjects daily over an extended period, so dose‐response models with time‐dependent parameters were estimated. Pooling between data sets produced seven common dose‐response models and one time‐dependent model. These pooled common models had data sets with different test subject hosts, and between disparate leptospiral strains tested on identical hosts. Comparative modeling was done with parallel tests to test the effects of a single different variable of either strain or test host and quantify the difference by calculating a dose multiplication factor. Statistical pooling implies that the mechanistic processes of leptospirosis can be represented by the same dose‐response model for different experimental infection tests even though they may involve different host species, routes, and leptospiral strains, although the cause of this pathophysiological phenomenon has not yet been identified.  相似文献

Customer product returns are key cost drivers that eat into online retailers’ profits. However, management research has neglected to examine ways of reducing return rates without causing a concomitant decrease in sales. Drawing from signalling and dissonance theories, we investigate the relationship between online retailers’ reputation and product return rates. Two experiments designed to produce causal conclusions show that reputation reduces return rates (Studies 1 and 2) and that return motivation is a boundary condition for that relationship (Study 2). A field study based on an online consumer panel demonstrates the robustness of the negative impact of online retailer reputation on product returns in a setting that emphasizes external validity (Study 3), in comparison with Studies 1 and 2, which maximize internal validity. Study 3 also examines managerially important contingencies of the causal relationship by considering three variables: purchase frequency; retailer type; and customer gender. Overall findings indicate that an online retailer's reputation is a powerful means of reducing product return rates. The findings also show that the strength of the relationship between reputation and product returns is influenced by return motivation and the three variables investigated in the field study.  相似文献
