Purpose The research objective of this study is to understand how institutional changes to the EU regulatory landscape may affect corresponding institutionalized operational practices within financial organizations. Design/methodology/approach The study adopts an Investment Management System as its case and investigates different implementations of this system within eight financial organizations, predominantly focused on investment banking and asset management activities within capital markets. At the systems vendor site, senior systems consultants and client relationship managers were interviewed. Within the financial organizations, compliance, risk and systems experts were interviewed. Findings The study empirically tests modes of institutional change. Displacement and Layering were found to be the most prevalent modes. However, the study highlights how the outcomes of Displacement and Drift may be similar in effect as both modes may cause compliance gaps. The research highlights how changes in regulations may create gaps in systems and processes which, in the short term, need to be plugged by manual processes. Practical implications Vendors abilities to manage institutional change caused by Drift, Displacement, Layering and Conversion and their ability to efficiently and quickly translate institutional variables into structured systems has the power to ease the pain and cost of compliance as well as reducing the risk of breeches by reducing the need for interim manual systems. Originality/value The study makes a contribution by applying recent theoretical concepts of institutional change to the topic of regulatory change uses this analysis to provide insight into the effects of this new environment

In order to bring conceptual clarity to a particular dimension of the relationship between the jus ad bellum and the jus in bello regimes, this article explores the independent sources of a military targeting rule in both branches of international law. The aim is not to displace the jus in bello as the ‘lead’ regime on how targeting decisions must be made, or to undermine the traditional separation between these regimes. Rather, conceptual light is shed on a sometimes assumed but generally neglected dimension of the jus ad bellum’s necessity and proportionality criteria that may, in limited circumstances, have significance for our understanding of human protection during war, by covering possible gaps in the jus in bello targeting rules.

The nature and extent of pre-Columbian (pre-1492 AD) human impact in Amazonia is a contentious issue. The Bolivian Amazon has yielded some of the most impressive evidence for large and complex pre-Columbian societies in the Amazon basin, yet there remains relatively little data concerning the land use of these societies over time. Palaeoecology, when integrated with archaeological data, has the potential to fill these gaps in our knowledge. We present a 6,000-year record of anthropogenic burning, agriculture and vegetation change, from an oxbow lake located adjacent to a pre-Columbian ring-ditch in north-east Bolivia (13°15’44” S, 63°42’37” W). Human occupation around the lake site is inferred from pollen and phytoliths of maize (Zea mays L.) and macroscopic charcoal evidence of anthropogenic burning. First occupation around the lake was radiocarbon dated to ~2500 years BP. The persistence of maize in the record from ~1850 BP suggests that it was an important crop grown in the ringditch region in pre-Columbian times, and abundant macroscopic charcoal suggests that pre-Columbian land management entailed more extensive burning of the landscape than the slash-and-burn agriculture practised around the site today. The site was occupied continuously until near-modern times, although there is evidence for a decline in agricultural intensity or change in land use strategy, and possible population decline, from ~600-500 BP. The long and continuous occupation, which predates the establishment of rainforest in the region, suggests that pre-Columbian land use may have had a significant influence on ecosystem development at this site over the last ~2000 years.

Clouds and associated precipitation are the largest source of uncertainty in current weather and future climate simulations. Observations of the microphysical, dynamical and radiative processes that act at cloud scales are needed to improve our understanding of clouds. The rapid expansion of ground-based super-sites and the availability of continuous profiling and scanning multi-frequency radar observations at 35 and 94 GHz have significantly improved our ability to probe the internal structure of clouds in high temporal-spatial resolution, and to retrieve quantitative cloud and precipitation properties. However, there are still gaps in our ability to probe clouds due to large uncertainties in the retrievals. The present work discusses the potential of G band (frequency between 110 and 300 GHz) Doppler radars in combination with lower frequencies to further improve the retrievals of microphysical properties. Our results show that, thanks to a larger dynamic range in dual-wavelength reflectivity, dual-wavelength attenuation and dual-wavelength Doppler velocity (with respect to a Rayleigh reference), the inclusion of frequencies in the G band can significantly improve current profiling capabilities in three key areas: boundary layer clouds, cirrus and mid-level ice clouds, and precipitating snow.

Arbuscular mycorrhizal fungi (AMF) are crucial to the functioning of the plant–soil system, but little is known about the spatial structuring of AMF communities across landscapes modified by agriculture. AMF community composition was characterized across four sites in the highly cleared south-western Australian wheatbelt that were originally dominated by forb-rich eucalypt woodlands. Environmentally induced spatial structuring in AMF composition was examined at four scales: the regional scale associated with location, the site scale associated with past management (benchmark woodlands with no agricultural management history, livestock grazing, recent revegetation), the patch scale associated with trees and canopy gaps, and the fine scale associated with the herbaceous plant species beneath which soils were sourced. Field-collected soils were cultured in trap pots; then, AMF composition was determined by identifying spores and through ITS1 sequencing. Structuring was strongest at site scales, where composition was strongly related to prior management and associated changes in soil phosphorus. The two fields were dominated by the genera Funneliformis and Paraglomus, with little convergence back to woodland composition after revegetation. The two benchmark woodlands were characterized by Ambispora gerdemannii and taxa from Gigasporaceae. Their AMF communities were strongly structured at patch scales associated with trees and gaps, in turn most strongly related to soil N. By contrast, there were few patterns at fine scales related to different herbaceous plant species, or at regional scales associated with the 175 km distance between benchmark woodlands. Important areas for future investigation are to identify the circumstances in which recolonization by woodland AMF may be limited by fungal propagule availability, reduced plant diversity and/or altered chemistry in agricultural soils.

Cell migration is a highly coordinated process and any aberration in the regulatory mechanisms could result in pathological conditions such as cancer. The ability of cancer cells to disseminate to distant sites within the body has made it difficult to treat. Cancer cells also exhibit plasticity that makes them able to interconvert from an elongated, mesenchymal morphology to an amoeboid blebbing form under different physiological conditions. Blebs are spherical membrane protrusions formed by actomyosin-mediated contractility of cortical actin resulting in increased hydrostatic pressure and subsequent detachment of the membrane from the cortex. Tumour cells use blebbing as an alternative mode of migration by squeezing through preexisting gaps in the ECM, and bleb formation is believed to be mediated by the Rho-ROCK signaling pathway. However, the involvement of transmembrane water and ion channels in cell blebbing has not been examined. In the present study, the role of the transmembrane water channels, aquaporins, transmembrane ion transporters and lipid signaling enzymes in the regulation of blebbing was investigated. Using 3D matrigel matrix as an in vitro model to mimic normal extracellular matrix, and a combination of confocal and time-lapse microscopy, it was found that AQP1 knockdown by siRNA ablated blebbing of HT1080 and ACHN cells, and overexpression of AQP1-GFP not only significantly increased bleb size with a corresponding decrease in bleb numbers, but also induced bleb formation in non-blebbing cell lines. Importantly, AQP1 overexpression reduces bleb lifespan due to faster bleb retraction. This novel finding of AQP1-facilitated bleb retraction requires the activity of the Na+/H+ pump as inhibition of the ion transporter, which was found localized to intracellular vesicles, blocked bleb retraction in both cell lines. This study also demonstrated that a differential regulation of cell blebbing by AQP isoforms exists as knockdown of AQP5 had no effect on bleb formation. Data from this study also demonstrates that the lipid signaling PLD2 signals through PA in the LPA-LPAR-Rho-ROCK axis to positively regulate bleb formation in both cell lines. Taken together, this work provides a novel role of AQP1 and Na+/H+ pump in regulation of cell blebbing, and this could be exploited in the development of new therapy to treat cancer.

The focus of Corporate Governance is shifting from the role of directors to active ownership. Based on their fiduciary duty to other shareholders, it is believed that institutional investors have an important role to play in this regard. However, the Pension Funds and the Sovereign Wealth Organisations are not driven by the same set of objectives. In addition, Environmental Social and Governance (ESG) issues in investment decision-making are now becoming more important and they are capable of becoming the mainstream in the future. However, there are widespread variations in perception of fiduciary responsibilities, ESG issues appraisal, as well as the strategies adopted by institutional investors on shareholder engagement as responsible investors. Responsible Investment market is largely driven by institutional investors and they are expected to continue to lead the way. This research work investigates the role of the main asset owners and their advisors in responsible investment practices in the UK. It adopts a qualitative approach using semi-structured interviews, questionnaire and meetings observations. Gathered data is analysed using grounded theory and the findings highlight the perception of the various investor groups to corporate governance. The research work contributes to the body of knowledge by assessing the corporate governance perspectives of the various classes of institutional investors which may have practical implications for other countries.

An increasing degree of attention is being given to the ecosystem services which insect pollinators supply, and the economic value of these services. Recent research suggests that a range of factors are contributing to a global decline in pollination services, which are often used as a “headline” ecosystem service in terms of communicating the concept of ecosystem services, and how this ties peoples׳ well-being to the condition of ecosystems and the biodiversity found therein. Our paper offers a conceptual framework for measuring the economic value of changes in insect pollinator populations, and then reviews what evidence exists on the empirical magnitude of these values (both market and non-market). This allows us to highlight where the largest gaps in knowledge are, where the greatest conceptual and empirical challenges remain, and where research is most needed.

Small-scale anaerobic digester installation has been a development objective of the Indian government to provide rural households clean fuel. Anaerobic digester installation is heavily subsidised. Depending on caste, the rate of subsidy offered for the smallest system available (1m3) varies between 32.35% and 41.18% of the total installation price. Yet, there are gaps in knowledge regarding the usefulness of such subsidies from a sustainability perspective. A cost-benefit analysis was conducted to evaluate the circumstances required for digester sustainability. The analysis used household data collected from 115 cattle owning households in Odisha, India to evaluate profitability at three levels of subsidy (none, General caste subsidy, and Schedule Caste/Schedule Tribe subsidy). Additional analyses considered the effect of; taking a loan, replacing electric lighting with biogas lighting, and the wealth level of the household. The results indicated that access to subsidy improved profitability. Yet, profitability could be achieved without the use of subsidy. The level of benefit accrued by households was similar independent of wealth. However, the provision of subsidy was essential for ensuring profitability for those households required to take a loan to meet the expense of installation. Such findings highlight the importance of subsidy as a means of including the poor.

Recent global assessments have shown the limited coverage of protected areas across tropical biotas, fuelling a growing interest in the potential conservation services provided by anthropogenic landscapes. Here we examine the geographic distribution of biological diversity in the Atlantic Forest of South America, synthesize the most conspicuous forest biodiversity responses to human disturbances, propose further conservation initiatives for this biota, and offer a range of general insights into the prospects of forest species persistence in human-modified tropical forest landscapes worldwide. At the biome scale, the most extensive pre-Columbian habitats across the Atlantic Forest ranged across elevations below 800 masl, which still concentrate most areas within the major centers of species endemism. Unfortunately, up to 88% of the original forest habitat has been lost, mainly across these low to intermediate elevations, whereas protected areas are clearly skewed towards high elevations above 1200 masl. At the landscape scale, most remaining Atlantic Forest cover is embedded within dynamic agro-mosaics including elements such as small forest fragments, early-to-late secondary forest patches and exotic tree mono-cultures. In this sort of aging or long-term modified landscapes, habitat fragmentation appears to effectively drive edge-dominated portions of forest fragments towards an early-successional system, greatly limiting the long-term persistence of forest-obligate and forest-dependent species. However, the extent to which forest habitats approach early-successional systems, thereby threatening the bulk of the Atlantic Forest biodiversity, depends on both past and present landscape configuration. Many elements of human-modified landscapes (e.g. patches of early-secondary forests and tree mono-cultures) may offer excellent conservation opportunities, but they cannot replace the conservation value of protected areas and hitherto unprotected large patches of old-growth forests. Finally, the biodiversity conservation services provided by anthropogenic landscapes across Atlantic Forest and other tropical forest regions can be significantly augmented by coupling biodiversity corridor initiatives with biota-scale attempts to plug existing gaps in the representativeness of protected areas.

Este relatório trata de uma pesquisa com o objetivo geral de analisar a Intenção de Comportamento Antiético do executivo de vendas e alguns de seus possíveis determinantes, contemplando lacunas relevantes de conhecimento na realidade brasileira. Trata-se de uma replicação de estudo realizado nos Estados Unidos por SCHWEPKER Jr. (1999). Nesta linha, dois foram os objetivos específicos. O primeiro deles foi descrever o perfil dos construtos Julgamento Moral, Desenvolvimento Moral Cognitivo, Intensidade Concorrencial e Intenção de Comportamento Antiético numa amostra brasileira. O segundo objetivo específico foi investigar, na mesma amostra, as relações potenciais entre Julgamento Moral e Desenvolvimento Moral Cognitivo (variáveis explicativas), Intensidade Concorrencial (variável mediadora) e Intenção de Comportamento Antiético (variável explicada). Dados foram obtidos do principal executivo de vendas de 138 das maiores empresas brasileiras. Na amostra, quanto ao nível médio dos respondentes: a) 36% têm um padrão de Julgamento Moral inferior ou moderado; b) 53% têm um padrão de Desenvolvimento Moral Cognitivo inferior ou moderado; c) 29% têm um padrão de Intenção de Comportamento Antiético inferior ou moderado; d) 33% têm uma percepção de Intensidade Concorrencial inferior ou moderada. Algumas variáveis dos construtos Julgamento Moral, Desenvolvimento Moral Cognitivo e Intensidade Concorrencial possuem uma relação linear significativa com algumas variáveis do construto Intenção de Comportamento Antiético. Ao final deste relatório são apresentadas e discutidas as limitações e conclusões da pesquisa.

Atualmente, há uma grande cobrança da sociedade para que as empresas privadas se desenvolvam de forma sustentável e responsável. ou seja. tenham práticas de Responsabilidade Social Corporativa (RSC). No turismo. esse debate é ainda mais eminente. pois muitas localidades vivem e dependem do setor. que ao mesmo tempo, traz muitos impactos nocivos. Algumas cidades brasileiras. como Paraty (RJ). revitalizaram a sua economia por meio do turismo. após longos anos de abandono. entretanto elas tentam manter o seu desenvolvimento de forma equilibrada. sem prejudicar as peculiaridades locais. Ao analisar os temas sustentabilidade e RSC. observa-se que os mesmos possuem uma literatura ainda em construção. com resultados fragmentados. pouco conclusivos e deixando muitas lacunas teóricas. Além disso. também há poucos estudos sobre a gestão hoteleira em Paraty. sendo este o principal subsistema do turismo. Sendo assim. esse estudo investigou de forma exploratória. operacionalizadas por meio de entrevistas em profundidade. qual a percepção e formas de atuação dos gestores dos meios de hospedagem de Paraty. localizados em seu centro histórico. Com isso. foram entrevistados gestores de oito meios de hospedagem da cidade. selecionados por faixa de preços. O universo desse estudo é composto por cerca de 30 pequenas empresas. Os dados foram analisados por meio da técnica de análise conteúdo. Os gestores foram os sujeitos entrevistados. porque são os principais decisores e promotores do desenvolvimento sustentável nesses empreendimentos. Concluiu-se que. as características dos meios de hospedagem estudados diferem de acordo com a sua faixa de preço. Ao mesmo tempo. independente das diferenças veriticadas. as formas de gestão. assim como a percepção e formas de atuação de RSC. se assemelham a estudos analisados em pequenas empresas. estes pouco abordados na Administração. Além disso. todos os gestores entrevistados têm consciência em relação aos aspectos positivos e negativos da cidade. dos impactos do turismo e das suas responsabilidades para minimizar/potencializar esses impactos. Apesar do seu conhecimento sobre a RSC não ser sistematizado e as suas formas de atuação não estarem incluídas no planejamento constante da empresa. os mesmos demonstram ter senso de cidadania, consciência e propensão em investir cada vez mais na gestão sustentável do turismo na cidade. Por fim. constatou-se que a percepção e formas de atuação desses gestores. não é exatamente convergente pelo que é proposto por grande parte da literatura de RSC e sustentabilidade. apesar de serem formas autênticas e concretas de promover um desenvolvimento sustentável e equilibrado.
