Der Marktplatz E-Energy aus elektrizitätswirtschaftlicher Perspektive

The E-Energy Market is the place in a future energy system that integrates the markets for energy and Information/Communication Technologies (ICT). From the economic perspective of electricity, business models and business cases can already be developed for sub-markets and sub-areas of network load management, wholesale marketing and energy-market regulations, which as core elements manage consumer load in the mass customer area. As it turns out, the expected surplus value for all business cases is still tightly assessed and the E-Energy Market is therefore no automatic process. It has been assumed that the costs of the necessary information and communication technologies either do not have to be observed or are relatively insignificant. Additionally, considerable fine-tuning of the design of the sub-markets and the regulatory framework is necessary in order to enable the possibility for the business cases to be implemented. In a larger perspective, however, this market will play an important role when it comes to optimizing the power system around fluctuating power generation.     

Economic valuation of cultural heritage sites: A choice modeling approach

Despite growing attention by researchers and policy makers on the economic value of cultural heritage sites, debate surrounds the use of adequate methods. Although choice modeling techniques have been applied widely in the environmental economics field, their application in tourism and cultural economics has been much more limited. This paper contributes to the knowledge on the economic valuation of cultural heritage sites through a national choice modeling study of Old Parliament House, Australia. The study sought to value marginal changes in several attributes of this site and revealed that only some of them are valued positively: extending the period of temporary exhibitions, hosting various events, and having ‘shop and café’ and ‘fine dining’. Advantages of using a mixed logit model are provided and managerial and policy implications are discussed.     

Tourists’ emotional wellness and hotel room colour

In response to the growing wellness trend, the tourism and hospitality industry has offered various wellness services and facilities. Despite the significance of emotion in wellness, research on emotional wellness is surprisingly scant. The present empirical study examined the underlying dimensions of emotional wellness and the influence of guest room colour on emotional wellness via hypotheses testing. Results indicated that calmness is the most dominant dimension of emotional wellness. Results also suggest that a cool colour-themed guest room, particularly green, is preferable. Theoretical and managerial implications are discussed, and future research suggestions are provided.     

The impact of the cessation of blogs within the UK police blogosphere

This article investigates the concept of influence within a group of police work‐bloggers. During the period studied (2007–2013), three influential police bloggers, well‐known within the small and tightly knit UK police blogosphere, abruptly ended their blogging activity. Their cessation stimulated others to reconsider their own blogging and led to several bloggers ceasing to blog for fear of being outed and disciplined or because they had been warned by superiors. This can be seen as part of a wider phenomenon as increasing blog surveillance has resulted in a reduction of work‐related blogs. The study shows that work‐blogging cessation is influenced by the activities or perceived activities of bloggers' peers and that, while internal factors were influential in the creation of new work‐blogs, external factors—in particular, fear of consequences for their career—were the predominant influences on their cessation.     

Justifying Redevelopment ‘Failures' Within Urban ‘Success Stories': Dispute,Compromise, and a New Test of Urbanity

Large‐scale waterfront redevelopment projects, an urban development phenomenon that originated in the 1970s, are attractive to a growing suite of cities worldwide. But why? These mega‐projects are full of pitfalls, broken promises, cost overruns, disappointments and are often accused of promoting inequality. In this article, we consider the specific case of Melbourne's Docklands, which local popular opinion has roundly judged a failure despite the countervailing judgment of success in the revival of ‘liveability' of the adjacent Melbourne central business district. We use the Docklands case to illustrate the utility of a ‘critical pragmatic' framework of analysis to get behind dominant explanations of the demands of the urban growth machine and postmodern neoliberal capitalism. Without denying the existence of these dynamics, nor their hegemony, we nevertheless explicate how a critical pragmatic analysis can reveal the social dynamics driving the judgments and justifications offered by actors in urban redevelopment. A pragmatic analysis of these dynamics of argument and action at critical moments in the long process of an urban redevelopment can reveal new kinds of compromises and tests by which these projects are judged. In other words, what counts as failure and as success in the work of city building will shift, depending on what actors do and how they talk about it, and on how well these actions and justifications hold up to public challenges about the true character of a successful city. By gauging how these challenges are constituted and settled, we can better understand the evolution of the urban value proposition, and the new notion of justice grounded in urbanity that is emerging at the urban redevelopment frontier.     

The transformative and emancipatory potential of participatory evaluation: reflections from a participatory action research study with war-affected young mothers

The Participatory Action Research (PAR) study with Young Mothers in Liberia, Sierra Leone and northern Uganda which took place from 2006 to 2009 aimed to understand what ‘reintegration’ meant to young mothers formerly associated with armed groups. It also implemented social action initiatives designed by study participants to promote their wellbeing and achieve reintegration. We evaluated the study using multiple participatory evaluation methods, situating evaluation as part of the cycle of research and action. This approach facilitated young mothers’ participation in developing the criteria by which the study and its reintegration outcomes would be judged. We describe each method and what we uniquely learned from using a participatory evaluation approach. We discuss how this approach is well-suited for complex studies, can enhance data quality, increases capacity of all involved in the evaluation and supports the critical reflexivity necessary for participatory studies to succeed.     

Risk factor and industry effects in the cross-country comovement of momentum returns

This paper examines the sources of cross-country comovement of momentum returns over the 1975–2004 period. Using data on more than 17,000 individual firms across 100 industries from 40 countries, we document the profitability of country-neutral individual firm, industry, and industry-adjusted return momentum. We show that country-neutral momentum returns are significantly correlated across countries, the correlation is time-varying, and that comovement among industries cannot explain the comovement of country-neutral momentum returns. However, we find that standard risk factor models do explain a significant portion of the cross-country comovement of momentum returns, even though they do not explain average momentum returns.     

Geographic Portfolio Allocations,Property Selection and Performance Attribution in Public and Private Real Estate Markets

This article examines the effects of geographic portfolio concentrations on the return performance of U.S. public real estate investment trusts versus private commercial real estate over the 1996–2013 time period. Adjusting private market returns for differences in geographic concentrations with public markets, we find that core private market performance falls. Using return performance attribution analysis, we find that the geographic allocation effect constitutes only a small portion of the total return difference between listed and private market returns, whereas individual property selection within geographic locations explains, in part, the documented outperformance of listed versus private real estate market returns.     

联邦制森林治理:分权管理经验和潜在影响

80%以上的发展中国家和经济转轨国家正在进行着某种形式的分权试验。以11个国家(拥有全球森林总量60%以上)为例,简要描述了实施联邦制的主要林业国家当前的森林行政管理类型以及施政形式,认为分权后强化了跨部门联系的重要性,许多政府机构都介入了有关森林资源的各项决策;有效的森林治理取决于各种管理机构的能力;私营部门和民间组织在成功治理各种森林资源中也发挥着重要作用。从11国经验中分析了各种潜在优势、潜在危险,指出分权管理减少了中央政府的官僚和决策障碍,但会使全国性的政策协调、实施和监督变得困难。
