A Common Market Measure for Libor and Pricing Caps, Floors and Swaps in a Field Theory of Forward Interest Rates

The main result of this paper that a martingale evolution can be chosen for Libor such that all the Libor interest rates have a common market measure; the drift is fixed such that each Libor has the martingale property. Libor is described using a field theory model, and a common measure is seen to be emerge naturally for such models. To elaborate how the martingale for the Libor belongs to the general class of numeraire for the forward interest rates, two other numeraire's are considered, namely the money market measure that makes the evolution of the zero coupon bonds a martingale, and the forward measure for which the forward bond price is a martingale. The price of an interest rate cap is computed for all three numeraires, and is shown to be numeraire invariant. Put-call parity is discussed in some detail and shown to emerge due to some non-trivial properties of the numeraires. Some properties of swaps, and their relation to caps and floors, are briefly discussed.Comment: 28 pages, 4 figure

The views of selected NGOs on corporate social disclosures in Bangladesh

Although prior studies looked at corporate social disclosures (CSD hereafter) mainly from the managerial perspective there are very few studies which examined CSD from a non-managerial stakeholder perspective. This paper contributes to that limited CSD literature. It does so from a developing country perspective. The main aim of this paper is to examine the views of selected NGOs on current CSD practices in Bangladesh using Gramscian hegemonic analysis. For this purpose, semi-structured interviews were carried out in the selected social and environmental NGOs of both overseas and Bangladesh origin. The results suggest that NGOs viewed the current CSD practice as far from satisfactory. They also argued that it is mainly aimed at maintaining corporate interests of image building. The study suggests that it is not corporations to be blamed alone for production of CSD in the interests of business, it is the capitalist society that consents to such reproduction of CSD

The absence of corporate social responsibility reporting in Bangladesh

This paper aims to broaden the present corporate social responsibility (CSR) reporting literature by extending its focus to the absence of CSR reporting within a developing country, an area which, to date, is relatively under researched in comparison to the more widely studied presence of CSR reporting within developed Western countries. In particular this paper concentrates upon the lack of disclosure on three particular eco-justice issues: child labour, equal opportunities and poverty alleviation. We examine why this is the case and thereby illuminate underlying motives behind corporate unwillingness to address these issues. For this purpose, 23 semi-structured interviews were undertaken with senior corporate managers in Bangladesh. The findings suggest that the main reasons for non-disclosure include lack of resources, the profit imperative, lack of legal requirements, lack of knowledge/awareness, poor performance and the fear of bad publicity. Given these findings the paper raises some serious concerns as to why corporations would ever be expected to voluntarily report on eco-justice issues where performance is poor and negative publicity would be generated and profit impaired. Further research is still required to uncover current injustices and to imagine what changes can be made

Intellectual capital disclosures by South African companies:a longitudinal investigation

Most of the previous studies on intellectual capital disclosures have been conducted from developed countries' context. There is very limited empirical evidence in this area from the context of emerging economies in general and Africa in particular. This paper is one of the early attempts in this regard. The main purpose of this study is to examine the extent and nature of intellectual capitaldisclosures in ‘Top 20’ South African companies over a 5 years period (2002–2006). The study uses content analysis method to scrutinise the patterns of intellectual capital disclosures during the study period. The results show that intellectual capital disclosures in South Africa have increased over the 5 years study period with certain firms reporting considerably more than others. Out of the three broad categories of intellectual capital disclosures human capital appears to be the most popular category. This finding stands in sharp contrast to the previous studies in this area where external capital was found to be most popular category

Marching with the Volunteers: Their Role and Impact on Beneficiary Accountability in an Indonesian NGO

Purpose: The purpose of this paper is to examine the role of volunteers and its impact on related accountability practices towards beneficiaries by a large humanitarian non-governmental organisation (NGO) in Indonesia. Design/methodology/approach: The authors adopted a qualitative case study design. The empirical evidence comes from rich fieldwork carried out in an Indonesian NGO. The authors collected the evidence mainly via 46 interviews and five focus groups. Findings: The authors found that the case NGO drew heavily on the social and cultural capitals of volunteers in the process of serving its beneficiaries, which, in turn, facilitated the enhancement of its accountability to the beneficiaries. The authors also found that volunteers play a bridging role to reduce the distance between NGOs and beneficiaries. Research limitations/implications: For NGO managers, this study provides necessary empirical evidence on the positive role played by the volunteers in the development and operationalisation of accountability to the beneficiaries. In the authors’ case, beneficiary accountability is enhanced by the social conduct and practices performed by the NGO’s numerous volunteers. Beneficiary accountability is of significant concern to the policy makers too. This study shows that volunteers and NGO can work in a reciprocal relationship where social and cultural capital can be mobilised to each other’s advantage. To facilitate beneficiary accountability, NGOs can draw on the socio-cultural capitals held by the volunteers who appear to share the same norms and expectations with the beneficiaries. This process can also lead to the building of social and cultural capital by the volunteers themselves as they achieve great satisfaction and gain valuable experience in this process that could lead to greater satisfaction in their spiritual and material lives. Originality/value: The authors extend the previous literature on beneficiary accountability by highlighting the under-researched role of volunteers in such accountability practices. In this paper, the authors first discuss the facilitating role of volunteers in enhancing NGOs’ accountability towards beneficiaries. Then, this is illustrated empirically. In addition, the authors argue that although Bourdieusian concepts like field and capital have been widely used in the analysis of various organisational practices the concept of habitus received limited attention particularly from the context of developing countries. The authors undertake an examination of the habitus of volunteers in the Indonesian case organisation and explore their linkages with the field and associated capitals

The big 4 in Bangladesh:caught between the global and the local

Purpose- This article explores the work practices of Big 4 firms in Bangladesh with the aim of exploring the extent to which Global Professional Service Firms can be thought of as being genuinely ‘global’. Methodology/Approach- Interviews were undertaken with the vast majority of Big 4 partners in Bangladesh. These interviews explored a number of themes related to the professional service work context in Bangladesh and the relationship between local and global firms. Findings- The central finding of this paper is that although the Big 4 have a long-established presence in Bangladesh, local societal factors heavily influence the realities of work for accountants there. In most cases the Big 4 firms establish correspondent firms (instead of full member firms) in Bangladesh and tend to offer restricted service lines. Additionally, the paper identifies professional, commercial and cultural barriers to greater Big 4 involvement in the local market. Conceptually, the chief contribution of this paper is to explore how the effects of globalising capitalism and standardised ‘best practices’ in global professional service work are mediated through the societal effects of Bangladeshi society, resulting in the Big 4 having only a tentative presence in the Bangladeshi market. Research implications- The findings cast doubt on the extent to which self-styled Global Professional Service firms are truly ‘global’ in nature. Future work examining the Big 4, or accounting more generally, in the context of globalization, would do well to pay greater attention to the experience of professionals in emerging markets. Originality/Value- Whilst there has been much work looking at accounting and accountants in the context of globalization, this work has tended to privilege ‘core’ western empirical settings. Very little is known about Professional Service Firms in ‘peripheral’ or emerging markets. Furthermore, this study extends the application of the System, Society and Dominance framework by mapping the interactions and dynamics of these three sources of influence in the setting of PSFs

This article appeared in Journal of Applied Physics 107, 024311 (2010) and may be found at https://doi.org/10.1063/1.3275889.We study the existence of Li-related shallow and deep acceptor levels in Li-doped ZnO nanocrystals using electron paramagnetic resonance (EPR) and photoluminescence (PL) spectroscopy. ZnO nanocrystals with adjustable Li concentrations between 0% and 12% have been prepared using organometallic precursors and show a significant lowering of the Fermi energy upon doping. The deep Li acceptor with an acceptor energy of 800 meV could be identified in both EPR and PL measurements and is responsible for the yellow luminescence at 2.2 eV. Additionally, a shallow acceptor state at 150 meV above the valence band maximum is made responsible for the observed donor-acceptor pair and free electron-acceptor transitions at 3.235 and 3.301 eV, possibly stemming from the formation of Li-related defect complexes acting as acceptors.DFG, 43659573, SFB 787: Halbleiter - Nanophotonik: Materialien, Modelle, Bauelement

Buckling behavior of straight slot tubesunder oblique loading – A comparative study

Hollow tubes are the most important or crucial parts of the rapidly growing automobile and construction industry. The tube is subjected to pure buckling. In theanalysis, one end is fixed and the force is applied to theother end and by application of different angles of inclinations ranging from 0˚ to 20˚ with different thicknessof the range of 0.5 to 2.0. Linear buckling code was used forfinding the critical buckling load. This research paper is about the effects of buckling under oblique loading. It is the process in which the tube is subjected to compressive oblique loading and the tube fails by the first increase in crossectional area and then bulging on any of the sides but in the case, oblique loading in hollow tube shell bulges internally or inside the perimeter of the tube
