Examining the moderating role of brand loyalty among consumers of technology products

The long-term survival of a company depends on its economic sustainability. It costs several times more to acquire new customers than retain current ones, and loyal customers spend more than new ones. Unfortunately, consumers are increasingly becoming less loyal to brands/products than before. Unearthing the underlying reasons for this diminishing consumer loyalty is critical. This forms the motivation of this study, which aims to examine the moderating role of loyalty among consumers of technology products. Specifically, the study explores the heterogeneity in the factors (antecedents) influencing brand-loyal attitudes and behavior among consumers of different loyalty levels. A total of 355 survey responses were obtained from an administrated survey across three loyalty groups (high loyalty—155; medium loyalty—99; low loyalty—90) in the United Arab Emirates. Structural equation modeling and multi-group moderation tests were used to test the hypothesized differences in the relationships between antecedents (trust, self-image, quality, and perceived ease of use) and customer attitude, and between customer attitude and repurchase intentions among the different loyalty groups. The results show that the different levels of loyalty have a moderating impact on the relationships. The findings are useful for marketers to better understand and manage customer attitudes, and subsequent purchase/repurchase intention depending on the levels of loyalty they may be in, as well as maneuver their customers through the different levels of loyalty to achieve business sustainability

Management of Non-Pulmonary Forms of Tuberculosis : Review of TRC Studies over Two Decades

Tuberculosis Research Centre, Chennai has been conducting randomized controlled clinical trials in both adults and children (n = 1015) in various non-pulmonary forms of tuberculosis, for the last two decades. This communication discusses the salient findings of these studies. The important finding is that short course chemotherapeutic regimens have been proven to be highly effective in tuberculosis of spine, superficial tuberculous lymphadenitis, abdominal tuberculosis, brain tuberculoma and Potts paraplegia. However, in tuberculous meningitis, the outcome appears to be directly related to the stage of the disease on admission. The intermittent regimens have been found to be as effective as daily regimens. The other important aspects highlighted are the need to obtain bacteriological/histo-pathological confirmation by resorting to relevant diagnostic procedures, value of Mantoux as a diagnostic tool and role of surgery

Benchmarking the research performance of United Arab Emirates with gulf cooperation council countries – A bibliometric study

The research performance of a country is an indicator of its scientific progress and benchmarking it with regional countries is critical to assess a country’s regional competitiveness. This study aims to assess and benchmark the research productivity of the United Arab Emirates (UAE) against other member nations of the Gulf Cooperation Council (GCC), namely with Saudi Arabia, Oman, Kuwait, Qatar, and Bahrain, who have similar macroeconomic and socio-cultural characteristics. Scopus was used as the data source to extract the research output of each of the six countries studied for the period 1995–2019. Bibliometric indicators covering both quantity and impact of research such as publication output, citation, and collaboration indicators were used to assess the research performance of UAE and other GCC countries. The findings indicate good progress in the UAE’s overall research performance during the period of study. Also, UAE’s research performance in most of the bibliometric indicators is comparable or superior to the other GCC countries. This study is the first of its kind and addresses the dearth of bibliometric studies assessing UAE’s research productivity and GCC countries in general. The findings are useful for administrators and policymakers to benchmark the performance of the UAE with other GCC countries, including its impact, growth, and trajectories. For researchers, the study indicators and methods can be replicated to assess the overall research performance of other countries

Intestinal dysfunction in liver cirrhosis: its role in spontaneous bacterial peritonitis

Spontaneous bacterial peritonitis is a common illness in patients with cirrhosis and ascites that occurs without any apparent focus of infection. Bacterial translocation plays an important role in spontaneous bacterial peritonitis and it is evident from a variety of studies that the gut is a major source of this bacteria. Gut motility alterations, along with bacterial overgrowth and changes in intestinal permeability, probably play a role in this bacterial translocation. The present review looks at the role of the intestine in spontaneous bacterial peritonitis induced by liver cirrhosis and the factors influencing bacterial translocation in this disease

Costs to patients with tuberculosis treated under DOTS programme

Background: The economic burden of TB in India is enormous as TB perpetuates and exacerbates poverty. Revised National Tuberculosis Control Programme (RNTCP) based on DOTS strategy is currently being implemented in India. The purpose of this study is to estimate the costs incurred by tuberculosis patients treated under RNTCP in a district in Tamilnadu where services are decentralized for diagnosis and treatment. Method: In all, 455 patients registered under RNTCP between June and December 2000, in Tiruvallur district were interviewed to collect the following information: Demographic, socio-economic characteristics of patients, expenditure incurred due to illness and effect of illness on employment. Based on the data collected, various costs (direct medical, nonmedical, indirect and total costs incurred on account of tuberculosis before and during treatment) were estimated. In addition Standard of Living Index (SLI) was calculated for patients. Results: Of 455 patients, 62% had low SLI. The median direct, indirect and total costs for 343 patients who successfully completed treatment were as follows: pre treatment direct costs were Rs 340, during treatment direct costs Rs 100; more than 50% of patients did not incur any indirect costs in both pre treatment and during treatment periods and overall total costs were Rs 1398. About 12% of patients lost more than 60 workdays and after completing treatment, 88% returned to work. Conclusion: For patients registered under RNTCP in Tiruvallur district in Tamilnadu, the findings that the total patient costs were Rs 1398/- and also the patients returned to work early establishes the economic benefits to patients treated under DOTS and lend support to rapid expansion of DOTS programme, particularly in low-income countries

Short-course chemotherapy in neuro-tuberculosis - Brief review of clinical trials undertaken at the Tuberculosis Research Centre, Madras

Tuberculosis of the nervous system can present as tuberculous meningitis, tuberculoma of brain, Potts paraplegia, tuberculosis of spine and rarely as arachnoiditis and vasculitis. Tuberculosis is conventionally treated for 12 to 18 months to ensure adequate cure, stabilise quiescence and prevent relapses. With the introduction of rifampicin and pyrazinamide it became feasible to shorten the duration of chemotherapy to 6 to 9 months. Many controlled clinical trials conducted all over the world have confirmed the success of this approach in pulmonary tuberculosis by evolving 100% effective SCC regimens 1-5. In a few studies especially tuberculous lymphadenitis, tuberculous abdomen and pericarditis SCC has also been used and found to be as effective as conventional regimens6,7. However, only recently has SCC been tried for neurotuberculosis. This presentation briefly highlights some of the chemotherapy trials conducted at the Tuberculosis Research Centre in some areas of CNS tuberculosis8-10. What is SCC? SCC refers to chemotherapeutic regimens containing powerful bactericidal drugs like INH, Rifampicin and Pyrazinamide, by the use of which the duration of treatment of TB is reduced from the conventional 12 to 18 months to 6 to 9 months

A Dangerous Twist of the 'T' Wave: A Case of Wellens' Syndrome

Wellens’ syndrome is a condition in which electrocardiographic (ECG) changes indicate critical proximal left anterior descending artery narrowing occurring during the chest pain-free period. Due to the severity of the obstruction, if such cases are managed by early invasive revascularisation therapy, a major threat in the form of a massive myocardial infarction or sudden death may be averted. We present the case of a patient with previous chest pain, whose ECG showing subtle ischemic changes was initially overlooked. A repeat ECG taken during the painless period showed a biphasic T wave, suggestive of Wellen’s’ syndrome. This was confirmed by an immediate coronary angiogram

Identifying effective communication channels in a rural community: A field report from south India

Background: There is scarcity of information on communication channels in rural areas where about 38% of people are illiterate. Objective: To identify the channels of communication available in rural areas by interviewing key informants. Method: This study was conducted in 51 villages of Ellapuram block, Tiruvallur district, Tamil Nadu in the year 2004. Key informants selected from the villages were interviewed by a Medical Social Worker. The questionnaire included information on modes of communication channels, availability of markets, public facilities, and local associations. Result: The study block included 9893 households covering a population of 39255. Their main occupation was agriculture (86%). Electricity was available in all the villages. More than 80% of the villagers had community TV/cable connections, >50% of the villages had cinema star fan associations, mahila mandals, youth clubs, self-help groups, anganwadi centres and ration shops. The main source of communication as per interview was television (100%), wallposters (55%); publicity through panchayat office meetings (53%) and dandora or beat of drums(43%). Conclusion: Main communication channels, commonly used to disseminate information were TV and wall posters. More than 50% of villages had local associations which can be used for effective communication. This information is vital for disseminating important information on public health programmes and educating the rural community
