Explaining university student loyalty: theory, method, and empirical research in Chile

Purpose The purpose of this paper is to explain student loyalty beyond its customary relationship with student satisfaction by including two relational variables, trust and commitment, two cognitive traits (service familiarity and communication) and one affective trait (opportunism) as moderators of the impact of trust and commitment on loyalty. Design/methodology/approach Two relational constructs (trust and commitment) are employed to improve the loyalty model and key comparisons are performed to know if career, cohort and sourcing school generate differences in the explanation of student loyalty. Findings Results show that the explanation chain that starts with student satisfaction but continues with the development of student trust and the reaching of student commitment culminates with student loyalty. The moderators (student opportunism, service familiarity, communication, age and available income for education) significantly contribute to the explanatory power of the model. Career is a meaningful differentiator in reaching student loyalty as are student cohort and the type of high school from which the student came. Research limitations/implications This is one of first empirical studies on university student loyalty. Future research could test the same or new hypotheses using different samples and contexts. Practical implications University policies may benefit from the inclusion of norms regarding relational processes and outcomes such as the value of trust in the interactions and systematic recognition and awards assigned to student commitment achievements. Originality/value The explanation chain of customer loyalty was successfully applied to student loyalty, and strengthened with the addition of meaningful moderating variables.
Agricultural Exports and Economic Growth in Nigeria: An Econometric Analysis

It has been observed that export promotion drive boosts economic growth of developing countries (Nigeria inclusive) through the multiplier effects that the income earned from exports has on the economy. Prior to the discovery of oil, agriculture has been the main contributor to the Nigerian external sector. It is in the light of this that this study sets out to examine the impact of agricultural export on Nigeria’s economic growth. This study used the Autoregressive Distribution Lag (ARDL) econometric technique to analyze the long run relationship and the impact of agricultural exports on Nigeria’s economic growth. Economic growth is the dependent variable, and is proxied by the real gross domestic product, the explanatory variables include: agricultural export, foreign direct investment, inflation rate and the labour force. The results from the ARDL technique revealed that agricultural exports significantly affect Nigeria’s economic growth; this suggests that, a 1percent increase in - agricultural export will boost economic growth in Nigeria by approximately 25percent.Therefore, from the results, the study recommended that agricultural export need to be promoted through the increase in agricultural production base.

The Nutraceuticals: A Voluminous Torrent in Pharmaceuticals-coupling Health & Drugs

The present review is focused on the nutraceuticals which are present in our surroundings having an excellent impact over the health of humans but are not known for their pharmaceutical use. Nutraceuticals include vitamins, minerals and other dietary supplements, which may be herbs, enzymes, animal extracts etc. Various researchers have proved that nutraceuticals are having an important role in reducing the risk of various diseases such as diabetes, cardiovascular diseases, Parkinson’s disease etc. with very few or negligible side effects.
What Does Today’s Smile Imply About Future Volatilities?

This article presents a simple and financially justifiable way to extract the evolution of the smile surface in the (ℚ) measure from today’s plain-vanilla option prices. By combining this information with (ℙ)-measure estimation of the dependence of implied volatility on the underlying, one can 1) obtain information about the existence and magnitude of a volatility risk premium; 2) devise trading strategies; and 3) price options such as forward volatility agreements (FVAs). TOPICS: Options, analysis of individual factors/risk premia, factor-based models, style investing Key Findings • Plain-vanilla smiles of different maturities are compatible with an infinity of future smiles, but these are linked by strong consistency relationships, which are identified. • Using these consistency relationships and very mild assumptions, we obtain the future smiles that are most compatible with space and time homogeneity and price today’s plain-vanilla options. • There is an interesting discrepancy between the dependence of ATM volatilities in the future smiles so obtained and the empirical dependence of the same quantity.
Does Strategic Planning Improve Organizational Performance? A Meta‐Analysis

Strategic planning is a widely adopted management approach in contemporary organizations. Underlying its popularity is the assumption that it is a successful practice in public and private organizations that has positive consequences for organizational performance. Nonetheless, strategic planning has been criticized for being overly rational and for inhibiting strategic thinking. This article undertakes a meta-analysis of 87 correlations from 31 empirical studies and asks, Does strategic planning improve organizational performance? A random-effects meta-analysis reveals that strategic planning has a positive, moderate, and significant impact on organizational performance. Meta-regression analysis suggests that the positive impact of strategic planning on organizational performance is strongest when performance is measured as effectiveness and when strategic planning is measured as formal strategic planning. This impact holds across sectors (private and public) and countries (U.S. and non-U.S. contexts). Implications for public administration theory, research, and practice are discussed in the conclusion.
Monetary Policy Setting in Australia, Canada and the Euro Area: Insights from the Shadows

Voting by shadow monetary policy committees (SMPCs) provide hints about monetary policy decisions. We examine data for Australia, Canada and the euro area. SMPCs release individual members' recommendations. Their central banks do not. How much variation is there in preferences towards inflation and output gaps? Do committees tend towards less extreme policy choices than individuals? We find little heterogeneity in preferences among committee members in Australia and Canada, but not for the shadow committee in the euro area. Our results may be relevant in understanding how the composition, structure and operation of committees in these economies impact monetary policy decisions. [ABSTRACT FROM AUTHOR]
Vitamin A status and inflammation during the first week of life in extremely premature infants at risk for bronchopulmonary dysplasia.

Vitamin A is a crucial antioxidant for premature infants because it protects the lungs from oxidative damage induced by the administration of supplemental oxygen. Although all premature infants are born with decreased vitamin A stores when compared to full-term infants, the vitamin A stores of premature infants at risk for BPD are often significantly deficient. Despite the increases in plasma vitamin A concentrations that have been achieved with vitamin A supplementation, only modest improvements in clinical outcomes and the incidence of BPD have been noted in this population. This article reviews the research on vitamin A supplementation for premature infants, as well as the issues and clinical implications associated with this intervention.
Cover Effects on Citations Uncovered: Evidence from Nature

Despite the prominent role played by bibliometric indicators for evaluating research, progress in pinning down the determinants of citation ows has so far been hindered by endogeneity issues. Based on 30 years of bibliometric data, we exploit a Regression Discontinuity Design to causally identify the effects that an article featured on the cover of the journal Nature has on citations to all articles by its authors. We confirm that, over time, cover articles are cited significantly more than non-cover articles, with this difference being long-lasting. However, when considering all articles by Nature authors, we find evidence of a crowding-out effect: the publication of a cover article causes citations to previous articles by its authors to decline sharply relative to citations to articles by non-cover authors.
Does it Matter When Labor Market Reforms are Implemented? The Role of the Monetary Policy Environment

Do labor market reforms initiated in periods of loose monetary policy yield different outcomes from those that were introduced in periods when monetary tightening prevailed? Since economic theory usually pays attention to the steady state change and ignores business cycle interactions of structural reforms, we connect local projection methodology with the Mallow’s Cp averaging criterion to arrive at an inference that does not require knowledge of the exact functional form, is robust to mis-specification, admits non-linearities, and cross-sectional dependence and addresses uncertainty regarding interactions between labor reforms and macroeconomy. We also develop a test to check the importance of monetary policy for any horizon and the entire impulse response function, taking the multiple testing problem into account. We document that replacement rates deliver substantially different outcomes on real GDP, inflation and real effective exchange rate, whereas labor activation schemes bear different effects on unemployment in low- and high-interest rate environments. There is also evidence of monetary policy trend playing an important role as well as increasing synchronized monetary and labor market policies across European countries.
Inflation Targeting: A New Framework for Monetary Policy?

In recent years a number of industrialized countries have adopted a strategy for monetary policy known as `inflation targeting. ' We describe how this approach has been implemented in practice and argue that it is best understood as a broad framework for policy, which allows the central bank `constrained discretion,' rather than as an ironclad policy rule in the Friedman sense. We discuss the potential of the inflation-targeting approach for making monetary policy more coherent and transparent, and for increasing monetary policy discipline. Our final section addresses some additional practical issues raised by this approach.
Prevención de la deficiencia de hierro y la anemia por ésta durante los primeros cinco años de vida

In both, industrialized and less industrialized countries throughout the world, iron deficiency is the most common nutritional deficiency disorder of infants and young children. Therefore, it is important to recognize the iron requirements during the first 5 years of life, the bioavailability of iron in the food (which depends on its form heme or non-heme iron) and the presence of inhibitors or enhancersof iron absorption. Strategies for eliminating iron deficiency in infants should be targeted predominantly to infants from low-income families, those who receive fed formulas not fortified with iron (regardless of economic status) or cow milk, and those who are predominantly breast-fed beyond the 4 month of age. Three major changes in dietary practices are suggested in order to satisfy the needs of absorbed iron by children from 1 to 5 years of age: 1) regular consumption of meats, fish and poultry if allowed by the economic situation of the family, 2) regular consumption of food fortified with ferrous sulfate or ferrous fumarate, and 3) to give special attention to the temporal relationship between the consumption of food used as iron source, and food which can contribute with the major inhibitors and enhancers of the non-heme iron absorption.
Human leptospirosis in Detroit and the role of rats as chronic carriers.

: Human leptospirosis was diagnosed in three patients from Detroit General Hospital. Epidemiological studies of these cases revealed heavy rat infestations in the residences of two of the patients. Leptospires serotype icterohaemorrhagiae were isolated from the rats and one of the patients. Cultural isolation was attempted from numerous blood and urine samples from each patient. Media containing different selective contaminant inhibitor substances was also utilized. Only two samples were culturally positive. It appears that very few viable cells are shed by human patients intermittently. Clinical reports and leptospirosis diagnosis are reported for each of the cases. The agglutinin-absortion test proved to be helpful in elucidating the true etiologic agent in the absence of cultural isolation. A serological survey for leptospirosis was conducted among swine slaughterhouse workers in Detroit. Significant titres to Leptospira pomona were observed.
Does economic globalisation affect income inequality? A meta‐analysis

A large volume of econometric literature has studied the impact of economic globalisation on income inequality around the world. However, reported econometric estimates vary substantially, which makes it difficult to draw valid conclusions. This paper presents a quantitative summary and analysis of existing estimates regarding the globalisation–inequality relationship. We use a new data set consisting of 1,254 observations from 123 primary studies. By applying meta‐analysis and meta‐regression methods, we obtain several main findings. First, globalisation has a (small‐to‐moderate) inequality‐increasing effect. Second, while the effect of trade globalisation is small, financial globalisation shows a more sizeable and significantly stronger inequality‐increasing impact. Third, we find an average inequality‐increasing impact of globalisation in both advanced and developing countries. Fourth, education and technology moderate the impact of globalisation on income inequality.
Credit Risk: Pricing, Measurement, and Management

In this book, two of America's leading economists provide the first integrated treatment of the conceptual, practical, and empirical foundations for credit risk pricing and risk measurement. Masterfully applying theory to practice, Darrell Duffie and Kenneth Singleton model credit risk for the purpose of measuring portfolio risk and pricing defaultable bonds, credit derivatives, and other securities exposed to credit risk. The methodological rigor, scope, and sophistication of their state-of-the-art account is unparalleled, and its singularly in-depth treatment of pricing and credit derivatives further illuminates a problem that has drawn much attention in an era when financial institutions the world over are revising their credit management strategies. Duffie and Singleton offer critical assessments of alternative approaches to credit-risk modeling, while highlighting the strengths and weaknesses of current practice. Their approach blends in-depth discussions of the conceptual foundations of modeling with extensive analyses of the empirical properties of such credit-related time series as default probabilities, recoveries, ratings transitions, and yield spreads. Both the "structura" and "reduced-form" approaches to pricing defaultable securities are presented, and their comparative fits to historical data are assessed. The authors also provide a comprehensive treatment of the pricing of credit derivatives, including credit swaps, collateralized debt obligations, credit guarantees, lines of credit, and spread options. Not least, they describe certain enhancements to current pricing and management practices that, they argue, will better position financial institutions for future changes in the financial markets. Credit Risk is an indispensable resource for risk managers, traders or regulators dealing with financial products with a significant credit risk component, as well as for academic researchers and students.
Takayas's Arteritis: Clinical presentation, treatment and importance of Triplex Carotid scanning

The authors present the case of a 25-year-old woman, with a long standing systemic inflammatory syndrome and non specific features. The patient was exhaustively studied as an inpatient but a firm diagnosis was not reached. 3.5 months after the initial symptoms and following a Transient Ischaemic Attack (TIA), the suspicion of Takayasu Arteritis was raised following a colour doppler flow image of the cervical vessels. The diagnosis was later confirmed by pan-aortography. The objective of this paper is to review the clinical features, monitoring of disease progression and treatment of, highlighting the role of colour doppler flow image in screening and follow-up of the disease.
Sexual Activity and Unprotected Sex Among Treatment Seeking HIV/AIDS Patients: A Multi-Site Study in Nigeria

Sexual activity without protection predisposes HIV infected individuals to re-infection of different strains and faster pro- gression to AIDS. With advance treatment and sense of well being, sexual activities among patients, continues. The present study using a multivariate design examined prevalence of sexual activity, unprotected sex and associated factors. HIV related factors (e.g.; drug use combination; knowledge of duration of HIV diagnosis) and Socio demographic factors (e.g.; multiple spouse; age, gender, ethnicity) were involved in a model of unprotected sex among HIV/AIDS patients seeking treatment in three tertiary Hospitals in Nigeria. Five hundred and two, (187(37.3%) males and 315 (62.7%) females) HIV/AIDS patients participated in the study. Mean age and mean time in months since diagnosis were 36.73 ± 9.38; 19.42 ± 23.12 respectively. Two hundred and sixty four (48%) were sexually active. One hundred and fifty three (58%) engaged in unprotected sex. Two variables: educational status and marital status were related to unprotected sex at (p<0.05). Median differences with Kruskal- Wallis H tests showed highest level of education, p = 0.018), and being currently married, p = 0.009 were associated with unprotected sex. Intervention to reduce unprotected sex among married patients with higher education should evolve among PLWHAs in Nigeria.
Red blood cell microrheology (clinical and pharmacological applications).

: In order to understand blood circulation, knowledge of the rheological properties of blood is required. However, the characteristic parameters which must be considered differ according to the circulatory region investigated. A distinction must therefore be made between the macrorheological parameters (viscosity, viscoelasticity) and the microrheological parameters (aggregation, cell deformability). As far as the microrheological parameters are concerned, red blood cell deformability is quite definitely the most important parameter in any physiopathological study of capillary circulation and the resulting exchanges. The main intrinsic parameters of red blood cell deformability are: inner viscosity of the cell, surface/volume ratio and membrane properties related to the lipid bilayer or to the cytoskeleton. Abnormal erythrocyte microrheology may result form alterations any one of these three parameters and would affect the ability of the cell to transit in the capillaries. Disturbances of red blood cell deformability are encountered in many clinical cases, mainly during anomalies relating to hemoglobin structure or its oxygen affinity, in constitutional deficiency of the membrane and during degenerative cardiovascular diseases or diseases which are considered to be atherosclerosis risk factors.
Diagnostic value of homocysteine and cystain C in type 2 diabetes patients with early stage of nephropathy

Objective To investigate the diagnostic value of homocysteine and cystain C in type 2 diabetes patients with early stage of nephropathy.Methods 110 cases with or without diabetic nephropathy were divided into three groups: diabete group(n=39),early diabetic nephropathy group(n=38) and end-stage nephropathy group(n=33). And the glomerular filtration rate,plasma homocysteine,serum cystain C,serum creatinine and blood urea nitrogen of the three groups were detected,and the relationships among the results above were analyzed.The authenticity,reliability and efficiency of homocysteine and cystain C in evaluating early stage of diabetic nephropathy in type 2 diabetes patients were evaluated.Results There were significant relationships among the levels of plasma homocysteine,serum cystain C and the glomerular filtration rate,serum creatinine,blood urea nitrogen in type 2 diabetes patients(r=-0.746,0.902,0.745 and-0.770,0.846,0.701). The levels of plasma homocysteine and serum cystain C had high authenticity and reliability in evaluating early stage of diabetic nephropathy(sensitivities were 87.32%,90.14% and specificities were 94.82%,100.00%). Conclusion It is suggested that homocysteine and cystain C can be used in clinical application as a new early diagnostic test.
