An Analysis Of The Levels And Patterns Of Shareholder Rights: 1990 - 2006

Greater attention is being paid to the issue of shareholder rights and corporate governance, particularly since the scandals of 1990s and 2000s and the stock market decline of the new millennium.  This study advances the concept of an optimum level of shareholder rights in corporate governance and analyzes the long-run trends in shareholder rights versus management entrenchment, using the G-Index.  This study finds that the level of shareholder rights generally has not increased, despite the legislative and regulatory reforms of the 2000s and contrary to the general perception.  Rather, shareholder rights have declined amongst the large, S&P 500 companies.  The paper also finds that there has been a tendency on the part of firms to converge to a median-level/norm of shareholder rights.  Evidence further suggests that firms are searching for an optimum level that balances the risks and rewards of greater shareholder rights

Isospin effects on the energy of vanishing flow in heavy-ion collisions

Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of $^{58}Ni$ + $^{58}Ni$ and $^{58}Fe$ +$^{58}Fe$ as a function of impact parameter. We found good agreement between our calculations and experimentally measured energy of vanishing flow at all colliding geometries. Our calculations reproduce the experimental data within 5%(10%) at central (peripheral) geometries

Corporate Governance: Shareholder Rights And Firm Performance

In the 21st century, greater attention is being paid to the issue of shareholder rights and corporate governance in U.S. corporations by regulators, shareholders and the general public.  A previous paper by the authors finds that the level of shareholder rights generally has not increased and may have declined amongst the S&P 500 companies, despite the recent legislative and regulatory reforms.  Evidence suggests that instead firms are searching for an optimum level of shareholder rights that balances the risks and rewards of greater shareholder rights.  This study investigates the financial performance of firms with greater shareholder rights (GSR) and contrasts it with that of firms with lower shareholder rights (LSR).  This paper finds that GSR firms may perform better on some financial criteria, in absolute terms, but when adjusted for volatility, LSR firms may perform better, contrary to the conventional wisdom

Critical appraisal of drug promotional literature using World Health Organisation guidelines

Background: Pharmaceutical marketing using drug promotional literatures is an important strategy adopted by the companies to promote their drugs. The primary objective of the present study is to compare the drug promotional literature of different pharmaceutical companies on the basis of World Health Organization (WHO) guidelines on ethical drug promotion.Methods: This observational, cross sectional study was conducted at a tertiary care hospital, Delhi. The promotional literature was evaluated in accordance with WHO guidelines, nature of claims, pictorial content presented in it and for the cited references.Results: A total of 208 promotional brochures were analysed. Only few (5.8%) of the promotional literature fulfilled all the criteria as mentioned by the guidelines. Nutritional supplements (27.9%) were the most promoted group of drugs. Pharmaceutical companies were most reluctant to provide information regarding contraindications (9.6%), adjuvants (11.5), side effects (10.6%) and drug interactions (9.6%). Generic name, brand name, dosage form, therapeutic indications were outlined in most of the brochures. Exaggerated emotional claims were made in 47.1% brochures, followed by that of efficacy in 39.4% and safety in 25% of brochures. Pictures of medicinal products outnumbered others with 39.9% followed by pictures of women, children and doctors with 20.7%, 17.3% and 13.5% respectively.Conclusions: Majority of the drug promotional literature did not comply with the ethical guidelines and was inadequate in terms of their adequacy, quality and reliability. Hence, it can be concluded that the majority of the promotional advertisements that are given to the prescribers are not able to spread awareness towards rational prescribing.

Susceptibility of staphylococci isolated from a burns unit to mupirocin and other antimicrobial agents

The activity of mupirocin (Bactroban) against coagulase-positive and coagulase-negative staphylococci isolated in a burns unit was tested to ascertain its effectiveness, and to detect any resistant isolates after continuous use of mupirocin for 2.5 years. A total of 395 staphylococci, consisting of 330 Staphylococcus aureus and 65 coagulase-negative staphylococci, were tested for resistance to mupirocin and other antimicrobial agents. The results showed that 94.5% of the isolates were fully susceptible to mupirocin (MIC ≤4 mg/l), and 5.3% expressed low-level resistance (MIC 8-128 mg/l). One Staphylococcus haemolyticus isolate expressed high-level resistance (MIC >1,024 mg/l). It transferred high-level mupirocin resistance to other staphylococci in conjugation experiments, which indicated a capacity to transmit mupirocin resistance between species. The results demonstrated that mupirocin was still highly effective against staphylococci in the burns unit. However, the demonstration that the resistant S. haemolyticus isolate could transfer high-level mupirocin resistance to other staphylococci was of concern. There is a compelling need to test staphylococci from clinical materials for mupirocin resistance. Early detection of resistance can prevent the establishment and spread of the mupirocin-resistant strains in the unit

Angiopoietin-like 4 based therapeutics for proteinuria and kidney disease

Current drugs used to treat proteinuric disorders of the kidney have been borrowed from other branches of medicine, and are only partially effective. The discovery of a central, mechanistic role played by two different forms of the secreted glycoprotein angiopoietin-like 4 (Angptl4) in human and experimental glomerular disease has opened new treatment avenues. Localized upregulation of a hyposialylated form (lacks sialic acid residues) of Angptl4 secreted by podocytes induces the cardinal morphological and clinical manifestations of human minimal change disease, and is also being increasingly recognized as a significant contributor toward proteinuria in experimental diabetic nephropathy. Oral treatment with low doses of N-acetyl-D-mannosamine, a naturally occurring precursor of sialic acid, improves sialylation of Angptl4 in vivo, and reduces proteinuria by over 40%. By contrast, a sialylated circulating form of Angptl4, mostly secreted from skeletal muscle, heart and adipose tissue in all major primary glomerular diseases, reduces proteinuria while also causing hypertriglyceridemia. Intravenous administration of recombinant human Angptl4 mutated to avoid hypertriglyceridemia and cleavage has remarkable efficacy in reducing proteinuria by as much as 65% for 2 weeks after a single low dose. Both interventions are mechanistically relevant, utilize naturally occurring pathways, and represent new generation therapeutic agents for chronic kidney disease related to glomerular disorders

The anaerobic bacteriology of intrapulmonary infections in Kuwait

Objective: The primary objective of this study was to ascertain the association of anaerobic bacteria in intrapulmonary infections and their susceptibility pattern to commonly prescribed antibiotics. Methods: One hundred clinical samples (85 broncho-alveolar lavage and 15 lung abscess aspirates) from suspected intrapulmonary infection cases were investigated in order to determine the role of anaerobic bacteria in these infections. The anaerobic bacterial isolates were identified by using the Vitek Anaerobic Card System and conventional methods. Susceptibility of these isolates was determined by Etest method against eight commonly prescribed antibiotics. Results: A total of 42 anaerobes were isolated, of which Prevotella spp. were the commonest isolates, made up of 42.9% (18/42), followed by Peptostreptococcus spp. 33.3% (14/42). Only two Bacteroides fragilis strains were isolated. All the isolates were sensitive to metronidazole, clindamycin, imipenem and meropenem; however, one Prevotella was resistant to piperacillin-tazobactam. The two B. fragilis isolates were susceptible to metronidazole, imipenem, meropenem and piperacillin-tazobactam, and one was found to be resistant to clindamycin. Conclusion: Overall, Prevotella spp. were found to be the predominant anaerobic bacteria associated with intrapulmonary infections in Kuwait. All the commonly prescribed antibiotics had excellent in vitro activities against nearly all the isolates

Empowering SMEs to make better decisions with Business Intelligence: A Case Study

With the advance of Business Information Systems (BIS), irrespective of the size, companies have adopted an approach to electronic data collection and management for two decades. The advancement in technology means they have in their possessions large volumes of historical data. Large organizations have cached on this and use a range of tools and techniques to leverage the usefulness of this information to make more informed business decisions. For most small and medium- sized enterprises (SMEs), however, such data typically sits in an archive without being utilized. While SMEs appreciate the need for utilizing historical data to make more informed business decisions, they often lack the technical knowhow and funding to embrace an effective BI solution. In this paper, drawing from our experience in implementing a BI solution for a UK SME we discuss some potential tools and strategies that could help SMEs overcome these challenges so as to reap the benefits of adopting an effective BI solution
