Identifying and assessing the application of ecosystem services approaches in environmental policies and decision-making.

The presumption is that ecosystem services (ES) approaches provide a better basis for environmental decision-making than other approaches because they make explicit the connection between human well-being and ecosystem structures and processes. However, the existing literature does not provide a precise description of ES approaches for environmental policy and decision-making, nor does it assess whether these applications will make a difference in terms of changing decisions and improving outcomes. We describe three criteria that can be used to identify whether and to what extent ES approaches are being applied: connect impacts all the way from ecosystem changes to human well-being; consider all relevant ES affected by the decision; consider and compare the changes in well-being of different stakeholders. As a demonstration, we then analyse retrospectively if and how the criteria were met in different decision-making contexts. For this assessment, we have developed an analysis format that describes the type of policy, the relevant scale(s), the decisions or questions, the decision-maker and the underlying documents. This format includes a general judgement of how far the three ES criteria have been applied. It shows that the criteria can be applied to many different decision-making processes, ranging from the supranational to the local scale and to different parts of decision-making processes. In conclusion we suggest these criteria could be used for assessments of the extent to which ES approaches have been and should be applied, what benefits and challenges arise, and whether using ES approaches made a difference in the decision-making process, decisions made, or outcomes of those decisions. Results from such studies could inform future use and development of ES approaches, draw attention to where the greatest benefits and challenges are, and help to target integration of ES approaches into policies, where they can be most effective.

Media representations of the nouveaux riches and the cultural constitution of the global middle class

The article offers a distinctive account of how the nouveaux riches serve as an anchor for a range of upper- middle- class ambivalences and anxieties associated with transformations of capitalism and shifting global hierarchies. Reflecting the long- term association of middle- class symbolic boundaries with notions of refinement and respectability, it examines how the discourse of civility shapes how the nouveaux riches are represented to the upper middle class, identifying a number of recurrent media frames and narrative tropes related to vulgarity, civility, and order. The author argues that these representations play a central role in the reproduction of the Western professional middle class, and in the cultural constitution of a global middle class — professional, affluent, urban, and affiliated by an aesthetic regime of civility that transcends national borders. The findings underline the significance of representations of the new super- rich as devices through which the media accomplish the global circulation of an upper- middle- class repertoire of cultural capital, which is used both to police shifting class boundaries and to establish a legitimate preserve for univorous snobbishness

Small farmers and sustainability: Institutional barriers to investment and innovation in the Malaysian palm oil industry in Sabah

The Malaysian palm oil industry is well known for the social, environmental and sustainability challenges associated with its rapid growth over the past ten years. Technologies exist to reduce the conflict between national development aims of economic uplift for the rural poor, on the one hand, and ecological conservation, on the other hand, by raising yields and incomes from areas already under cultivation. But the uptake of these technologies has been slow, particularly in the smallholder sector. In this paper we explore the societal and institutional challenges that influence the investment and innovation decisions of micro and small enterprise (MSE) palm oil smallholders in Sabah, Malaysia. Based on interviews with 38 smallholders, we identify a number of factors that reduce the smallholders' propensity to invest in more sustainable practices. We discuss why more effective practices and innovations are not being adopted using the concepts of, firstly, institutional logics to explore the internal dynamics of smallholder production systems, including attitudes to sustainability and innovation; and, secondly, institutional context to explore the pressures the smallholders face, including problems of access to land, labour, capital, knowledge and technical resources. These factors include limited access to global market information, corruption and uncertainties of legal title, weak economic status and social exclusion. In discussing these factors we seek to contribute to wider theoretical debates about the factors that block innovation and investment in business improvements in marginal regions and in marginalised groups

Experimental Evidence for Reduced Rodent Diversity Causing Increased Hantavirus Prevalence

Emerging and re-emerging infectious diseases have become a major global environmental problem with important public health, economic, and political consequences. The etiologic agents of most emerging infectious diseases are zoonotic, and anthropogenic environmental changes that affect wildlife communities are increasingly implicated in disease emergence and spread. Although increased disease incidence has been correlated with biodiversity loss for several zoonoses, experimental tests in these systems are lacking. We manipulated small-mammal biodiversity by removing non-reservoir species in replicated field plots in Panama, where zoonotic hantaviruses are endemic. Both infection prevalence of hantaviruses in wild reservoir (rodent) populations and reservoir population density increased where small-mammal species diversity was reduced. Regardless of other variables that affect the prevalence of directly transmitted infections in natural communities, high biodiversity is important in reducing transmission of zoonotic pathogens among wildlife hosts. Our results have wide applications in both conservation biology and infectious disease management

Politically connected boards and top executive pay in Chinese listed firms

Drawing on social comparison theory, this study examines the relationship between politically connected boards and top executive pay. Moreover, given the socialist orientation of China, tests are also carried out to establish the relationship between politically connected directors and pay dispersion across the firm. We find a negative association between politically connected boards and top executive pay. We also find that politically connected boards are negatively associated with pay dispersion, i.e., the higher the number of political directors on the board the smaller the gap between top executive pay and average employee pay. Finally, our study shows that politically connected directors weaken the pay-performance link. These findings have important theoretical, policy, and managerial implications

Mechanochemical Coupling in the Myosin Motor Domain. II. Analysis of Critical Residues

An important challenge in the analysis of mechanochemical coupling in molecular motors is to identify residues that dictate the tight coupling between the chemical site and distant structural rearrangements. In this work, a systematic attempt is made to tackle this issue for the conventional myosin. By judiciously combining a range of computational techniques with different approximations and strength, which include targeted molecular dynamics, normal mode analysis, and statistical coupling analysis, we are able to identify a set of important residues and propose their relevant function during the recovery stroke of myosin. These analyses also allowed us to make connections with previous experimental and computational studies in a critical manner. The behavior of the widely used reporter residue, Trp501, in the simulations confirms the concern that its fluorescence does not simply reflect the relay loop conformation or active-site open/close but depends subtly on its microenvironment. The findings in the targeted molecular dynamics and a previous minimum energy path analysis of the recovery stroke have been compared and analyzed, which emphasized the difference and complementarity of the two approaches. In conjunction with our previous studies, the current set of investigations suggest that the modulation of structural flexibility at both the local (e.g., active-site) and domain scales with strategically placed “hotspot” residues and phosphate chemistry is likely the general feature for mechanochemical coupling in many molecular motors. The fundamental strategies of examining both collective and local changes and combining physically motivated methods and informatics-driven techniques are expected to be valuable to the study of other molecular motors and allosteric systems in general

Preventing phone theft and robbery: the need for government action and international coordination

The banning of stolen handsets from networks has been around for 20 years, but remains little used internationally. Where used, its effectiveness is hindered by implementation problems, reprogramming, easy fencing opportunities, and international trafficking. Kill-switches where the user remotely disables a handset and deletes data have potential but, if non-permanent, are likely to experience similar limitations. This study proposes a set of responses to be adopted by national governments with international coordination

Transcription and Expression of Plasmodium falciparum Histidine-Rich Proteins in Different Stages and Strains: Implications for Rapid Diagnostic Tests

Background: Although rapid diagnostic tests (RDTs) for Plasmodium falciparum infection that target histidine rich protein 2 (PfHRP2) are generally sensitive, their performance has been reported to be variable. One possible explanation for variable test performance is differences in expression level of PfHRP in different parasite isolates. Methods: Total RNA and protein were extracted from synchronised cultures of 7 P. falciparum lines over 5 time points of the life cycle, and from synchronised ring stages of 10 falciparum lines. Using quantitative real-time polymerase chain reaction, Western blot analysis and ELISA we investigated variations in the transcription and protein levels of pfhrp2, pfhrp3 and PfHRP respectively in the different parasite lines, over the parasite intraerythrocytic life cycle. Results: Transcription of pfhrp2 and pfhrp3 in different parasite lines over the parasite life cycle was observed to vary relative to the control parasite K1. In some parasite lines very low transcription of these genes was observed. The peak transcription was observed in ring-stage parasites. Pfhrp2 transcription was observed to be consistently higher than pfhrp3 transcription within parasite lines. The intraerythrocytic lifecycle stage at which the peak level of protein was present varied across strains. Total protein levels were more constant relative to total mRNA transcription, however a maximum 24 fold difference in expression at ring-stage parasites relative to the K1 strain was observed. Conclusions: The levels of transcription of pfhrp2 and pfhrp3, and protein expression of PfHRP varied between different P. falciparum strains. This variation may impact on the detection sensitivity of PfHRP2-detecting RDTs

The English City Riots of 2011, "Broken Britain" and the retreat into the present

The responses to the English city riots of 2011 bear a remarkable resemblance to those of historical urban disorders in terms of the way in which they are framed by concerns over "moral decline", "social malaise" and a "lack of self-restraint" among certain sections of the population. In this paper we draw on the work of Norbert Elias and take a long-term perspective in exploring historical precedents and parallels relating to urban disorder and anti-social behaviour. We reject the notion of "Broken Britain" and argue that a more "detached" perspective is necessary in order to appreciate that perceived crises of civilisation are ubiquitous to the urban condition. Through this historical analysis, framed by Elias' theory of involvement and detachment, we present three key arguments. Firstly, that a 'retreat into the present' is evident among both policy discourse and social science in responding to contemporary urban disorder, giving rise to ahistorical accounts and the romanticisation of previous eras; secondly, that particular moral panics have always arisen, specifically focused upon young and working class populations and urban disorder; and, thirdly, that previous techniques of governance to control these populations were often far more similar to contemporary mechanisms than many commentaries suggest. We conclude by advocating a long-term, detached perspective in discerning historical precedents and their direct linkages to the present; and in identifying what is particular about today's concerns and responses relating to urban disorder
