The transparency that journalists and newsrooms can produce for their audience has long been regarded as a rather marginal criterion for journalistic quality. But new transparency models??due to the interactivity, immediacy, archiving capacity and the absent limitation of space in the internet??offer greater potentials than classical instruments in print and broadcasting. In comments, web videos, blogs, twitter feeds and social networks, journalists discuss with users and publicly account for editorial decisions. Transparency is fashionable in the digital public sphere; its evaluation, however, is not clear, but ambiguous and complex. This paper conceptualizes (self-)transparency and qualitatively classifies the available instruments in a three-dimensional matrix model. This is to facilitate the analysis of problematic areas and potential conflicts: Newsrooms demonstrating open self-reflection dismiss the ideal of ??objective journalism??. Yet, transparency is not only an ethical demand, but is also supposed to strengthen trust in journalistic products because it permits quality evaluations by the audience. An experiment shows, for the first time, that self-transparency has an effect on trust in some aspects but not as a basic principle. Analysing this interdependency, we have to distinguish between transparency of process and of product as well as between different media. 相似文献

We consider the problem of partitioning a ‘cake' C among n players. Various criteria have been considered for deciding whether a partition P1,P2,…,Pn of C, where piece Pi goes to player i, is a ‘good' partition. See, for example, Barbanel (1996) [Barbanel, J.B., 1996. Super envy-free cake division and independence of measures. J. Math. Anal. Appl. 197, 54–60] or Brams and Taylor (1996) [Brams, S.J., Taylor, A.D., 1996. Fair Division: From Cake-Cutting To Dispute Resolution. Cambridge Univ. Press]. In this paper we study certain real numbers (the ‘partition ratios' of this paper's Section 2) which can be associated in a natural way with any partition. We show that various types of products of these numbers provide us with useful information about certain trades and transfers between players. 相似文献

In this paper we examine plausible macroeconomic responses to the ex ante (planned but not implemented yet) reforms in the labor market, taking a currently proposed Social Model in Lithuania as an example. We contribute not only to the current debate on the efficacy of announced structural reforms, but also to the literature on policy evaluation, by assessing reforms from a global perspective. Taking trade linkages and openness into account, we demonstrate macroeconomic reactions to shocks in unemployment benefits, active labor market policies, and tax wedge on the reforming economy. In particular, we show that the omission of an international dimension could lead to seriously biased results on policy effects for any open and small economy. Using a satellite model for the intermediate trade, we link the global framework with the sectoral extensive margin, which changes some of the results derived from the aggregate data.

Financing pensions in the EU is a challenge. Many EU countries introduced private pension schemes to compensate declining public pension levels due to reforms made necessary by demographic change. In 2001, Germany introduced the Riester pension. Ten years after introduction the prevalence rate of this voluntary private pension scheme approximates 37 %. However, numerous criticisms raise doubts that the market for Riester products is transparent. Using the 2010 German SAVE survey, this article investigates terminated and dormant Riester contracts on a household level for the first time. Respectively 14.5 and 12.5 % of households who own or have owned a Riester contract terminated or set dormant their contract. We find that around 45 % of terminated or dormant Riester contracts are caused at least partly by product-related reasons, which is significantly higher than for endowment life insurance contracts. The uptake of a new contract after a termination is more likely if a termination is product-related. Nevertheless, after a termination 73 % of households do not sign a new contract, which can have serious long-term consequences for old-age income. Households with low income, low financial wealth or low pension literacy are more likely to have terminated or dormant contracts. Low income and low financial wealth households also have the lowest prevalence rate of Riester contracts and are at higher risk of old-age poverty. 相似文献

Past studies of the use of soil fertility management strategies by farmers usually model input use decisions based on the neoclassical utility/profit maximization principle in which farmers use soil fertility management inputs primarily to increase revenues and profits. However, there is, to date, no study that explains exactly how this decision-making process occurs and the role which personal values play in driving the choice of soil fertility management inputs. This article systematically maps the relationship between choice of soil fertility management strategy (attributes), its outcomes (consequences) and the personal values that motivate the choice. It specifically uses the means-end chain approach to construct hierarchical value maps that relate the attributes to consequences, and ultimately to the personal values. The study finds that the use of soil fertility management strategies by peri-urban fresh vegetable growers is driven by five personal values, namely happiness, comfortable life, independence, good/healthy life and achievement of life goals. It also finds that while farmers seek to increase profit (hence incomes), profit maximization is not the end driver of the use of soil fertility management inputs. It concludes that a lot more goes into farmers’ decision-making process relating to the use of soil fertility management practices than can be explained by the neoclassical profit/utility maximization principle. The study discusses the policy implications of these findings. 相似文献

Previous decompositions of risk-adjusted mutual fund performance might deliver biased results. In this paper, we provide new reliable insights on the drivers of mutual fund performance by decomposing risk-adjusted performance of U.S. equity mutual funds using the Generalized Calendar Time regression model. According to our results, out of all previously considered fund characteristics, only the negative effect of lagged fund size and the positive effects of lagged performance and lagged family size remain highly significant. Our analysis further suggests that much of the variation in previous empirical results can be attributed to methodological issues. 相似文献

The traditional view of nature-based tourists as a relatively homogeneous group has been questioned, and several scholars have suggested various segmentation typologies. This paper discusses market and industry changes and notes key trends, as Fordist tourist products have been replaced by post-Fordist and neo-Fordist products, with both McDonaldization and McDisneyization developments. A range of visitor-based typologies are reviewed, and the conflict between capturing the diversity of today's nature-based tourists while offering management bodies simple tools to segment visitors, identify core groups and improve their marketing is noted. In an attempt to overcome this conflict, the paper presents a conceptual framework which focuses on nature-based tourism products instead of tourist types, therefore incorporating aspects of both the demand and supply sides of the nature-based tourism industry market. A two-dimensional matrix is suggested, linking four basic travel motivations (nature conservation, nature experience, sports/adventure and hedonistic) to four different types of tourist products (independent, à la carte, customized and standardized), giving a total typology of 16 different types. The matrix should help protected area managers to better understand tourist needs, suggest management measures and help to create more sustainable forms of tourism. Empirical testing is suggested as a next step. 相似文献

In response to growing consumer concerns, developed‐country governments have reduced permissible pesticide residue levels in food. Many food retailers have developed even more stringent private food safety protocols relating to pesticide use, storage and disposal and passed them on to their suppliers. Exporters in developing countries enforce these developed‐country pesticide standards (DC‐PS) by subjecting farmers to close monitoring. This study explores the effects of enforcing compliance with DC‐PS on smallholder farmers’ pesticide‐related health costs. Results suggest that enforcing DC‐PS encourages farmers to use protection that lowers pesticide‐induced morbidity, hence reducing farmers’ health costs from pesticide exposure. The study concludes that there are health benefits to family farmers from complying with DC‐PS beyond the acknowledged income generation from selling fresh produce in premium export markets. 相似文献
