    A proposed scoring system for assessing the severity of actinic keratosis on the head: actinic keratosis area and severity index

    Background: Actinic keratosis (AK) severity is currently evaluated by subjective assessment of patients. Objectives: To develop and perform an initial pilot validation of a new easy-to-use quantitative tool for assessing AK severity on the head. Methods: The actinic keratosis area and severity index (AKASI) for the head was developed based on a review of other severity scoring systems in dermatology, in particular the psoriasis area and severity index (PASI). Initial validation was performed by 13 physicians assessing AK severity in 18 AK patients and two controls using a physician global assessment (PGA) and AKASI. To determine an AKASI score, the head was divided into four regions (scalp, forehead, left/right cheek ear, chin and nose). In each region, the percentage of the area affected by AKs was estimated, and the severities of three clinical signs of AK were assessed: distribution, erythema and thickness. Results: There was a strong correlation between AKASI and PGA scores (Pearson correlation coefficient: 0.86). AKASI was able to discriminate between different PGA categories: mean (SD) AKASI increased from 2.88 (1.18) for ‘light’ to 5.33 (1.48) for ‘moderate’, 8.28 (1.89) for ‘severe’, and 8.73 (3.03) for ‘very severe’ PGA classification. The coefficient of variation for AKASI scores was low and relatively constant across all PGA categories. Conclusions: Actinic keratosis area and severity index is proposed as a new quantitative tool for assessing AK severity on the head. It may be useful in the future evaluation of new AK treatments in clinical studies and the management of AK in daily practice

    A state-stewardship view on executive compensation

    We take a state-stewardship view on the corporate governance model and executive compensation policies in economies with strong political involvement. In such a highly politically-oriented institutional environment, the business elites are not just professional managers but are also de facto government officials who are directly state-appointed – even in ‘private’ firms. They are expected to act as responsible ‘stewards’ of the state. Consequently, their compensation may differ from what agency theory predicts. We test this state-stewardship view on China and find that Chinese managers are remunerated not for maximizing equity value but for increasing the value of the state-owned assets. Managerial compensation depends on political connections and prestige, and on the firms’ contribution to political and macroeconomic goals and the officials’ political achievements. These effects were somewhat weakened since the governance reform of 2006, when companies became more market-oriented though state influence still prevails. In a social welfare perspective, the compensation of state-steward managers stimulates not the maximization of shareholder value but the preservation of the state’s interests

    New East Manchester: urban renaissance or urban opportunism?

    In this paper we ask how a shrinking city responds when faced with a perforated urban fabric. Drawing on Manchester’s response to its perforated eastern flank - and informed by a parallel study of Leipzig - we use the city’s current approach to critique urban regeneration policy in England. Urban renaissance holds out the promise of delivering more sustainable - that is more compact, more inclusive and more equitable - cities. However, the Manchester study demonstrated that the attempt to stem population loss from the city is at best fragile, despite a raft of policies now in place to support urban renaissance in England. It is argued here that Manchester like Leipzig is likely to face an ongoing battle to attract residents back from their suburban hinterlands. This is especially true of the family market that we identify as being an important element for long-term sustainable population growth in both cities. We use the case of New East Manchester to consider how discourses linked to urban renaissance – particularly those that link urbanism with greater densities - rule out some of the options available to Leipzig, namely, managing the long-term perforation of the city. We demonstrate that while Manchester is inevitably committed to the urban renaissance agenda, in practice New East Manchester demonstrates a far more pragmatic – but equally unavoidable – approach. This we attribute to the gap between renaissance and regeneration described by Amin et al (2000) who define the former as urbanism for the middle class and the latter as urbanism for the working class. While this opportunistic approach may ultimately succeed in producing development on the ground, it will not address the fundamental, and chronic, problem; the combination of push and pull that sees families relocating to suburban areas. Thus, if existing communities in East Manchester are to have their area buoyed up – or sustained - by incomers, and especially families, with greater levels of social capital and higher incomes urban policy in England will have to be challenged

    Bureaucratization in Public Research Institutions

    The purpose of this paper is to analyse the nature of bureaucratization within public research bodies and its relationship to scientific performance, focusing on an Italian case-study. The main finding is that the bureaucratization of the research sector has two dimensions: public research labs have academic bureaucratization since researchers spend an increasing part of their time in administrative matters (i.e., preparing grant applications, managing grants/projects, and so on); whereas universities mainly have administrative bureaucratization generated by the increase over time of administrative staff in comparison with researchers and faculty. In addition, I show that research units with higher bureaucratization have lower scientific performance
