Feasibility of valuing credit risk in the financial market in Sri Lanka: a case study

The Sri Lankan financial market uses non analytical techniques to quantify credit risk. Credit derivatives are not used to transfer credit risk. A Credit Default Swap (CDS) is the most widely used credit derivative to manage credit risk. To evaluate the price of CDS, various sophisticated methods are used. This research paper focuses on techniques to hedge credit risk in the Sri Lankan financial market, the behaviours of CDS in derivative markets, calculating a fair value of CDS, the main advantages of using credit derivatives, and major imperfections to use the pricing process of CDS in the Sri Lankan marke

Availability legibility and adequacy of diagnosis as entered in bed head ticket in a base hospital Sri Lanka: a descriptive cross-sectional study

Introduction: Hospital information storage is done through an internationally accepted coding system. It is very important to have an accurate diagnosis for proper coding. Ministry of Health has issued a circular (No-01-05/99) for the documentation of Bed Head Ticket (BHT) including writing the correct diagnosis.  Objective: To assess the availability, legibility, and adequacy of diagnosis as entered in the BHTs of selected wards in a base hospital in Sri Lanka. Methods: Descriptive cross-sectional study was conducted to assess availability, legibility, and adequacy of diagnosis as entered in 384 BHTs of selected wards in a Base Hospital in Sri Lanka. A data Extraction sheet (DES) was used as a study instrument.  Results: Out of 384 BHTs diagnosis were not available in 12 (3.13%) BHTs and diagnosis were illegible in 36(6.99%) BHTs. In 244(67.59%) BHTs diagnosis were written as abbreviations. Only in136(37.46%) BHTs, diagnosis were written in block capital letters. Conclusion and recommendation: Documentation diagnosis in the BHTs is not according to the standards. Therefore, medical administrators, policymakers, and clinicians should take urgent actions to improve documentation diagnosis in BHTs

Adult liver transplantation in the congenital absence of inferior vena cava

Whereas congenital absence of inferior vena cava observed in paediatric population more often than not, as an isolated or syndromic variety, this is seldom encountered in adult liver transplant recipients. There appear few sporadic reports in the literature on experience of such anomaly in adults. Given the rarity of situation, surprising encounters of such anomalies may pose challenge to the unprepared transplant surgeon and unfavourable outcomes may even have resulted in under-reportage of this condition. In this brief report we document our recent experience with two such cases and this is supplemented with extensive reference to the literature on classification of such anomalies with the endeavour to document implications of such in the adult liver transplant setting.

The International Pulsar Timing Array: second data release

In this paper, we describe the International Pulsar Timing Array second data release, which includes recent pulsar timing data obtained by three regional consortia: the European Pulsar Timing Array, the North American Nanohertz Observatory for Gravitational Waves, and the Parkes Pulsar Timing Array. We analyse and where possible combine high-precision timing data for 65 millisecond pulsars which are regularly observed by these groups. A basic noise analysis, including the processes which are both correlated and uncorrelated in time, provides noise models and timing ephemerides for the pulsars. We find that the timing precisions of pulsars are generally improved compared to the previous data release, mainly due to the addition of new data in the combination. The main purpose of this work is to create the most up-to-date IPTA data release. These data are publicly available for searches for low-frequency gravitational waves and other pulsar science

Diagnostic accuracy studies: how to report and analyse inconclusive test results.

Failure to report inconclusive test results can lead to misleading conclusions regarding the accuracy and clinical usefulness of a diagnostic tool. We show that these results are often overlooked in research on test accuracy and provide guidance on suitable approaches to reporting and analysing these problematic results

The Well-Being of Executive-Level Working Women in Sri Lanka

Society, in general, recognizes men as breadwinners and women as housewives. The traditional role of women has changed because of education and work, providing women with more responsibilities. Within these dual roles, women undergo more pressure that negatively affects their well-being which hinders positive and meaningful outcomes of their physical, mental, and social development. Currently, the ‘well-being of women’ has become a debatable theme in the world community. Literature draws more attention to poor, rural, and less educated women. As women's roles have extended throughout every sector of society, it is important to identify the well-being of women who represent educated employees. This study used mixed research methods with a convenience sampling method adopted among 100 working women at the executive level. Data was collected via a survey, in-depth interviews, and discussions, and was analyzed critically. The study found that most informants who earn a considerable salary have been deprived of their well-being. Because of their very busy lives, they face role conflicts in fulfilling their responsibilities. Higher workload, lack of relaxation and recreation opportunities, negligence of personal health and other basic needs, as well as sexual harassment and social attitudes, etc., negatively affect their social, physical, and mental well-being. All in all, most women have been unable to utilize their education to achieve successful, healthy, and happy lives by improving their well-being. Taking more productive actions for the improvement of women's well-being in all aspects would be highly beneficial to women, families, and the entire society.

The detection of lubricating oil viscosity changes in gearbox transmission systems driven by sensorless variable speed drives using electrical supply parameters

Lubrication oil plays a decisive role to maintain a reliable and efficient operation of gear transmissions. Many offline methods have been developed to monitor the quality of lubricating oils. This work focus on developing a novel online method to diagnose oil degradation based on the measurements from power supply system to the gearbox. Experimental studies based on an 10kW industrial gearbox fed by a sensorless variable speed drive (VSD) shows that measurable changes in both static power and dynamic behaviour are different with lube oils tested. Therefore, it is feasible to use the static power feature to indicate viscosity changes at low and moderate operating speeds. In the meantime, the dynamic feature can separate viscosity changes for all different tested cases
