AN ANALYTICAL STUDY OF SUSTAINABLE HUMAN RESOURCE POLICIES AND TALENT MANAGEMENT IN INDIAN SCENARIO

In a recent survey of Indian CEO’s, it was suggested that Indian managerial leaders were less dependent on their personal charisma, but they emphasised logical and step by step implementation processes. Indian leaders focused on empowerment and accountability in cases of critical turnaround challenges, innovative challenges, innovative technology, product planning and marketing or when other similar challenges were encountered (Spencer, Rajah, Narayan, Mohan & Latiri 2007). These social scientists contend. Leaders in other countries often tell about why they chose a peculiar person for a certain role per task, detailing the personal characteristics that made that person right for that situation. They may also consider, in detail, how an assignment would help someone grow and develop their abilities. In general, Indian leaders simply did not discuss how they matched particular people to certain roles or tasks, nor did they usually consider in detail how the personal characteristics of individuals might shape or inform the best way to influence that person.

Corporate Nationality and Capital Structure Decisions - Evidence from India

This paper examines the Capital Structure of companies classified based on nationality over two-time phases as 2008-09 to 2012-13 and 2013-14 to 2017-18 covering ten years. For each category of companies, the mean of three gearing ratios i.e., Total debt to Net worth ratio, Long term debt to Net worth ratio and Short term debt to Net worth ratio is assessed. The analysis is based on a randomized sample of 206 companies obtained from BT-500 (December, 2017) which are subcategorized on the basis of nationality as Indian Domestic Companies, Indian MNCs operating abroad and Foreign MNCs operating in India. The findings reveal that Domestic Indian companies are more inclined towards debt relative to Indian MNCs and Foreign MNCs over both the time phases. This signifies the importance of the nationality factor which must be contemplated while planning Capital Structure. Statistically significant differences in total and long-term debt ratios of Domestic Indian Companies and Indian MNCs between Phase I and Phase II highlight the significance of the time factor which should also be kept in mind before taking leverage decisions. Overall, the paper suggests the corporations to have beady eyes on the institutional environment of geographical territories in which they operate as well as the time variations before planning their debt structure. The disparities in the debt ratios across nationality and time warrant an empirical investigation of the causes behind them, so examining the determinants of Capital Structure of DCs and MNCs would be an interesting area of research in the future

VLSI ARCHITECTURE FOR AN AREA-EFFICIENT COMPUTATION IN LTE TURBO DECODERS

Long Term Evaluation (LTE) has been used to achieve peak data rates in wireless communication system. Turbo codes are used as the channel encoding scheme. MAP algorithm has been used as a decoding scheme. Complexity in MAP algorithm is reduced by implementing the algorithm in log domain giving rise to Log MAP algorithm. The main objective of this work is to reduce the complexity of state metric computation by employing of various algorithms and these algorithms differ only by their implementation of correction terms. The ACS unit is implemented using constant log MAP algorithm, linear log MAP algorithm, MAX log MAP algorithm, multi step log MAP algorithm and hybrid log MAP algorithm. The state metric calculation is implemented with the help of radix-4 Add -Compare-Select (ACS) unit. The distance calculation involved between two concurrent computations of state metric can be shared among them which give rise to Maximum Shared Resource (MSR) architecture. The proposed implementation of these algorithms leads to reduction in the power dissipation, propagation delay and the number of logical elements used for the recursion computation in turbo decoders used in LTE system. The MSR architecture for recursion computation reduces the number of LUTs by 12.1% when compared with the existing

Fluorescent amplified fragment length polymorphism (FAFLP) genotyping demonstrates the role of biofilm-producing methicillin-resistant periocular Staphylococcus epidermidis strains in postoperative endophthalmitis

BACKGROUND: An observational case series was used to study the virulence characteristics and genotypes of paired Staphylococcus epidermidis isolates cultured from intraocular samples and from periocular environment of patients with postcataract surgery endophthalmitis. METHODS: Eight S. epidermidis isolates were obtained from three patients (2 from patients #1 and 2 and 4 from patient #3) whose vitreous and/or anterior chamber (AC) specimens and preoperative lid/conjunctiva samples were culture positive. Cultures were identified by API-Staph phenotypic identification system and genotypically characterized by Fluorescent Amplified Fragment Length Polymorphism (FAFLP) and checked for their antimicrobial susceptibility. The isolates were tested for biofilm-production and methicillin-resistance (MR) by PCR amplification of icaAB and mecA gene respectively. RESULTS: Four out of eight S. epidermidis strains showed multiple drug resistance (MDR). All the eight strains were PCR positive for mecA gene whereas seven out of eight strains were positive for icaAB genes. In all three patients FAFLP typing established vitreous isolates of S. epidermidis strains to be indistinguishable from the strains isolated from the patient's conjunctival swabs. However, from patient number three there was one isolate (1030b from lid swab), which appeared to be nonpathogenic and ancestral having minor but significant differences from other three strains from the same patient. This strain also lacked icaAB gene. In silico analysis indicated possible evolution of other strains from this strain in the patient. CONCLUSION: Methicillin-resistant biofilm positive S. epidermidis strains colonizing the conjunctiva and eyelid were responsible for postoperative endophthalmitis (POE)

Hacking into bacterial biofilms: a new therapeutic challenge

Microbiologists have extensively worked during the past decade on a particular phase of the bacterial cell cycle known as biofilm, in which single-celled individuals gather together to form a sedentary but dynamic community within a complex structure, displaying spatial and functional heterogeneity. In response to the perception of environmental signals by sensing systems, appropriate responses are triggered, leading to biofilm formation. This process involves various molecular systems that enable bacteria to identify appropriate surfaces on which to anchor themselves, to stick to those surfaces and to each other, to construct multicellular communities several hundreds of micrometers thick, and to detach from the community. The biofilm microbial community is a unique, highly competitive, and crowded environment facilitating microevolutionary processes and horizontal gene transfer between distantly related microorganisms. It is governed by social rules, based on the production and use of "public" goods, with actors and recipients. Biofilms constitute a unique shield against external aggressions, including drug treatment and immune reactions. Biofilm-associated infections in humans have therefore generated major problems for the diagnosis and treatment of diseases. Improvements in our understanding of biofilms have led to innovative research designed to interfere with this process

Effects of antiplatelet therapy after stroke due to intracerebral haemorrhage (RESTART): a randomised, open-label trial

Background: Antiplatelet therapy reduces the risk of major vascular events for people with occlusive vascular disease, although it might increase the risk of intracranial haemorrhage. Patients surviving the commonest subtype of intracranial haemorrhage, intracerebral haemorrhage, are at risk of both haemorrhagic and occlusive vascular events, but whether antiplatelet therapy can be used safely is unclear. We aimed to estimate the relative and absolute effects of antiplatelet therapy on recurrent intracerebral haemorrhage and whether this risk might exceed any reduction of occlusive vascular events. Methods: The REstart or STop Antithrombotics Randomised Trial (RESTART) was a prospective, randomised, open-label, blinded endpoint, parallel-group trial at 122 hospitals in the UK. We recruited adults (≥18 years) who were taking antithrombotic (antiplatelet or anticoagulant) therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage, discontinued antithrombotic therapy, and survived for 24 h. Computerised randomisation incorporating minimisation allocated participants (1:1) to start or avoid antiplatelet therapy. We followed participants for the primary outcome (recurrent symptomatic intracerebral haemorrhage) for up to 5 years. We analysed data from all randomised participants using Cox proportional hazards regression, adjusted for minimisation covariates. This trial is registered with ISRCTN (number ISRCTN71907627). Findings: Between May 22, 2013, and May 31, 2018, 537 participants were recruited a median of 76 days (IQR 29–146) after intracerebral haemorrhage onset: 268 were assigned to start and 269 (one withdrew) to avoid antiplatelet therapy. Participants were followed for a median of 2·0 years (IQR [1·0– 3·0]; completeness 99·3%). 12 (4%) of 268 participants allocated to antiplatelet therapy had recurrence of intracerebral haemorrhage compared with 23 (9%) of 268 participants allocated to avoid antiplatelet therapy (adjusted hazard ratio 0·51 [95% CI 0·25–1·03]; p=0·060). 18 (7%) participants allocated to antiplatelet therapy experienced major haemorrhagic events compared with 25 (9%) participants allocated to avoid antiplatelet therapy (0·71 [0·39–1·30]; p=0·27), and 39 [15%] participants allocated to antiplatelet therapy had major occlusive vascular events compared with 38 [14%] allocated to avoid antiplatelet therapy (1·02 [0·65–1·60]; p=0·92). Interpretation: These results exclude all but a very modest increase in the risk of recurrent intracerebral haemorrhage with antiplatelet therapy for patients on antithrombotic therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage. The risk of recurrent intracerebral haemorrhage is probably too small to exceed the established benefits of antiplatelet therapy for secondary prevention
