Studies on energy transformation in the freshwater snail Pila globosa 1. Influence of feeding rate

The effects of eleven chosen feeding levels ranging from 0 to 198 mg damp dry (plant) Ceratophyllumlg live snail /day on the absorption, conversion and metabolism of the snail Pi/a globosa (of 1•9 g body weight) have been studied. Absorption rates increased from 3•0 to 21•0 mg dry food /g live snail/day in snails fed 3-4-28'8 mg dry food/ g live snail/day. In these snails, absorption efficiency decreased from 87•5 to 73•0 %

An examination of the relationship of governance structure and performance: Evidence from banking companies in Bangladesh

Corporate governance has become increasingly important in developed and developing countries just after a series of corporate scandals and failures in a number of countries. Corporate governance structure is often viewed as a means of corporate success despite prior studies reveal mixed, somewhere conflicting and ambiguous, and somewhere no relationship between governance structure and performance. This study empirically investigates the relationship between corporate governance mechanisms and financial performance of listed banking companies in Bangladesh by using two multiple regression models. The study reveals that a good number of companies do not comply with the regulatory requirements indicating remarkable shortfall in corporate governance practice. The companies are run by the professional managers having no duality and no ownership interest for which they are compensated by high remuneration to curb agency conflict. Apart from some inconsistent relationship between some corporate variables, the corporate governance mechanisms do not appear to have significant relationship with financial performances. The findings reveal an insignificant negative impact or somewhere no impact of independent directors and non-independent non-executive directors on the level of performance that strongly support the concept that the managers are essentially worthy of trust and earn returns for the owners as claimed by stewardship theory. The study provides support for the view that while much emphasis on corporate governance mechanisms is necessary to safeguard the interest of stakeholders; corporate governance on its own, as a set of codes or standards for corporate conformance, cannot make a company successful. Companies need to balance corporate governance mechanisms with performance by adopting strategic decision and risk management with the efficient utilization of the organization’s resources

Communicated accountability by faith based charity organisations

The issue of communicated accountability is particularly important in Faith-Based Charity Organisations as the donated funds and use of those funds are often meant to fulfil religious obligations for the well-being of society. Integrating Stewart's (1984) ladder of accountability with the Statement of Recommended Practice guidance for charities, this paper examines communicated accountability practices of Muslim and Christian Charity Organisations in England and Wales. Our content analysis results indicate communicated accountability to be generally limited, focusing on providing basic descriptive information rather than judgement-based information. Our interviews with trustees and preparers of Trustee Annual Reports in Muslim Charity Organisations identified the reasons being due to high donor trust and consequently weak demand by stakeholders for the latter type of information, as well as internal organisational issues related to the organisational structure and culture, lack of internal professional expertise and high accountability cost.</p

The pancreas anatomy conditions the origin and properties of resident macrophages

We examine the features, origin, turnover, and gene expression of pancreatic macrophages under steady state. The data distinguish macrophages within distinct intrapancreatic microenvironments and suggest how macrophage phenotype is imprinted by the local milieu. Macrophages in islets of Langerhans and in the interacinar stroma are distinct in origin and phenotypic properties. In islets, macrophages are the only myeloid cells: they derive from definitive hematopoiesis, exchange to a minimum with blood cells, have a low level of self-replication, and depend on CSF-1. They express Il1b and Tnfa transcripts, indicating classical activation, M1, under steady state. The interacinar stroma contains two macrophage subsets. One is derived from primitive hematopoiesis, with no interchange by blood cells and alternative, M2, activation profile, whereas the second is derived from definitive hematopoiesis and exchanges with circulating myeloid cells but also shows an alternative activation profile. Complete replacement of islet and stromal macrophages by donor stem cells occurred after lethal irradiation with identical profiles as observed under steady state. The extraordinary plasticity of macrophages within the pancreatic organ and the distinct features imprinted by their anatomical localization sets the base for examining these cells in pathological conditions

Determinants of financial performance of Islamic banks: An intellectual capital perspective

Purpose The purpose of this paper is to empirically examine the effect of intangible resources, i.e. intellectual capital (IC) on financial performance of 64 Islamic financial institutions (IFIs) operating in 18 different countries for the period 2007-2011, while controlling for firm-specific variables, namely, bank size, level of risk, listing status, and firm complexity. Design/methodology/approach The required data to calculate different constituents of IC are derived from Bankscope database. Value Added Intellectual Coefficient (VAIC) methodology devised by Pulic is used to determine the impact of IC on financial performance of IFIs. Findings Results indicate a significant positive relationship between VAIC and accounting performance based on return on assets (ROA). The results further indicate a significant positive relationship between accounting performance and capital employed efficiency (CEE) and human capital efficiency (HCE), but no significant relationship with regards to structural capital efficiency. Overall, the results suggest that value creation capability of IFIs is highly influenced by HCE and CEE. Research limitations/implications The main limitation of the present study lies in its methodological tool, the VAIC methodology, which has been criticized by some researchers as not really measuring IC. Despite the inherent limitation of the VAIC methodology which relies on secondary data published in annual reports, it is still considered by some researchers as one of the best available tool to measure firms’ IC in the absence of access to detailed internal information on IC. Practical implications The findings may serve as a useful input for Islamic bankers in managing their investments in IC within their institutions. Originality/value The main contribution of this paper is to use a previously little-studied area, Islamic banking and finance, to identify the effect of intellectual capital on performance

Experiences of ICU survivors in a low middle income country - A multicenter study

Background Stressful patient experiences during the intensive care unit (ICU) stay is associated with reduced satisfaction in High Income Countries (HICs) but has not been explored in Lower and Middle Income Countries (LMICs). This study describes the recalled experiences, stress and satisfaction as perceived by survivors of ICUs in a LMIC. Methods This follow-up study was carried out in 32 state ICUs in Sri Lanka between July and December 2015.ICU survivors’ experiences, stress factors encountered and level of satisfaction were collected 30 days after ICU discharge by a telephone questionnaire adapted from Granja and Wright Results Of 1665 eligible ICU survivors, 23.3% died after ICU discharge, 49.1% were uncontactable and 438 (26.3%) patients were included in the study. Whilst 78.1% (n = 349) of patients remembered their admission to the hospital, only 42.3% (n = 189) could recall their admission to the ICU. The most frequently reported stressful experiences were: being bedridden (34.2%), pain (34.0%), general discomfort (31.7%), daily needle punctures (32.9%), family worries (33.6%), fear of dying and uncertainty in the future (25.8%). The majority of patients (376, 84.12%) found the atmosphere of the ICU to be friendly and calm. Overall, the patients found the level of health care received in the ICU to be “very satisfactory” (93.8%, n = 411) with none of the survivors stating they were either “dissatisfied” or “very dissatisfied”. Conclusions In common with HIC, survivors were very satisfied with their ICU care. In contrast to HIC settings, specific ICU experiences were frequently not recalled, but those remembered were reported as relatively stress-free. Stressful experiences, in common with HIC, were most frequently related to uncertainty about the future, dependency, family, and economic concerns

Sustainability disclosure and reputation: a comparative study

“This is a post-peer-review, pre-copyedit version of an article published in Corporate Reputation Review. The definitive publisher-authenticated version Corporate Reputation Review 14(2), pp.79-96 is available online at: http://www.palgrave-journals.com/crr/index.html”Drawing on legitimacy theory, we discuss that a company’s reputation is a determinant of sustainability disclosure. Specifically, we consider the concept of reputation into three dimensions for analysis: stakeholders’ commitment, financial performance and media exposure. This paper differs from previous social and environmental reporting studies in that it investigates both internal and external contextual factors that influence disclosure practice. We claim that companies with a good financial performance, that are adopting an active strategic position towards stakeholders and that are exposed to significant public pressure are more likely to use sustainability disclosure in order to communicate their legitimacy to operate to stakeholders. Moreover the paper analyses a wide range of corporate reports for their social and environmental content using an international sample that allows for a comparison of disclosure practices among Continental European, UK and USA companies. Our results show that stakeholder commitment and media exposure are positively associated with sustainability disclosure. Moreover, we find evidence that the drivers of disclosure vary by information type
