Socially integrative customer service (SICS) : identification of a symbiotic link with corporate social responsibility

The aim of this study is to answer the research question "can customer service be revitalised through identification of a symbiotic relationship with social responsibility, linked by people-centricity?" The concept of customer service remains weak and there has been a lack of attention to the underlying purpose: "to serve". To strengthen the theory the humanistic nature of the concept should be revised. Fundamental to this argument is the question of who is a customer? To fully discover the scope of the concept requires a broader or more specifically a societal view. Herein the theme of social corporate responsibility is critical to the recognition of the customer service network (CSN). This suggestion in isolation is useful but structural. Another aspect must be identified to validate the "service" ethos. Through this reasoning the relational theme (RT) provides for a mechanism for this to be achieved. Therefore the theory of socially integrative customer service is based on broadening and deepening the customer service concept. This study is illustrated in the context of the grocery retail sector in the Republic of Ireland. Four case studies are presented, three based on company-wide and in-store research and a fourth is a cross-company study. Results across companies indicate acceptance of the research question and show evidence to validate SICS. There is scope to further develop SICS and to build on the CSN and the RT. Finally the concept of SICS provides for a diverse basis for further research. This theory does no purport to cause a paradigm shift but does add innovation to the body of knowledge. As is the hallmark of good theoretical development, the author has aimed to keep the philosophy simple.

Motivating techniques within Irish and American manufacturing and service companies in the Northwest of Ireland

In today’s world, many companies are concentrating on both their technology and human resources to provide them with their competitive advantage. Hence, understanding what motivates people is particularly important for managers in order to develop and sustain a competitive edge. As a result, numerous theories have been advanced to help our understanding of the subject matter and from these theories many motivational methods have evolved to enhance motivation within the workplace. In addition, research has been conducted on the various types of motivational techniques utilised by companies within Ireland. However, very little research has been completed within specific geographical regions in Ireland concerning the types of motivational techniques implemented at different job levels and their impact on employees work performance. Thus the objective of this research was to identify the motivational techniques utilised at different job levels within large manufacturing and service companies in the Northwest of Ireland and examine how these techniques influence the performance levels of employees. Furthermore, the study examined if these companies have changed from traditional ways of motivating employees to newer techniques. The research methodologies used to undertake the research included interviews with the HR managers and questionnaires completed by different employees at various job levels within the participating companies. Overall the conclusions were varied. Many different types of motivation techniques were found within the study’s participating companies. Irish companies are improving their motivational techniques, however most of these techniques are only used within higher job levels. In contrast to their American counterparts, a variety of motivational techniques are utilised and implemented at all job levels. On a more positive note, the majority of these motivational techniques do increase performance levels at all job levels. From the extensive primary and secondary research conducted, the thesis concludes by offering a number of recommendations to assist companies in further development of their motivational techniques for all job levels. These recommendations hope to augment the success of companies through an enhanced motivated workforce.

An investigation into system security requirements and implementation in an Application Service Provider (ASP) environment

Although the ASP model has been around for over a decade, it has not achieved the expected high level of market uptake. This research project examines the past and present state of ASP adoption and identifies security as a primary factor influencing the uptake of the model. The early chapters of this document examine the ASP model and ASP security in particular. Specifically, the literature and technology review chapter analyses ASP literature, security technologies and best practices with respect to system security in general. Based on this investigation, a prototype to illustrate the range and types of technologies that encompass a security framework was developed and is described in detail. The latter chapters of this document evaluate the practical implementation of system security in an ASP environment. Finally, this document outlines the research outputs, including the conclusions drawn and recommendations with respect to system security in an ASP environment. The primary research output is the recommendation that by following best practices with respect to security, an ASP application can provide the same level of security one would expect from any other n-tier client-server application. In addition, a security evaluation matrix, which could be used to evaluate not only the security of ASP applications but the security of any n-tier application, was developed by the author. This thesis shows that perceptions with regard to fears of inadequate security of ASP solutions and solution data are misguided. Finally, based on the research conducted, the author recommends that ASP solutions should be developed and deployed on tried, tested and trusted infrastructure. Existing Application Programming Interfaces (APIs) should be used where possible and security best practices should be adhered to where feasible.

Preditores de viabilidade em pacientes com resposta negativa à ecocardiografia de estresse com dobutamina de baixa dose

FUNDAMENTO: A ecocardiografia de estresse com dobutamina de baixa dose é um teste específico para predizer disfunção de contratilidade reversível, mas mesmo assim, sua sensibilidade é menor do que ideal. OBJETIVO: Avaliar os preditores de recuperação miocárdica contrátil após a revascularização, em pacientes sem viabilidade na ecocardiografia de estresse com dobutamina de baixa dose. MÉTODOS: Trinta pacientes consecutivos foram selecionados consecutivamente, que apresentavam estenose coronária/oclusão significantes, tratáveis através de revascularização, anormalidade de motilidade de parede regional na distribuição da artéria afetada e ausência de viabilidade na ecocardiografia de estresse com dobutamina de baixa dose. Os pacientes foram submetidos a estudo de imagem com 99mTc-sestamibi em repouso e então submetidos à revascularização coronária bem sucedida. A ecocardiografia de seguimento foi realizada três meses depois. Os pacientes foram classificados em 2 grupos: grupo 1: com evidência de recuperação miocárdica contrátil após a revascularização na ecocardiografia de seguimento e grupo 2: sem evidência de recuperação miocárdica. Os dois grupos foram comparados em relação aos dados clínicos, ecocardiográficos e cintilográficos. RESULTADOS: A média da idade era 52,3 ± 5,9 anos e 97% eram do sexo masculino. A porcentagem de captação total de 99mTc-sestamibi foi significantemente mais alta no grupo 1 quando comparado ao grupo 2 (p < 0,01) e foi o preditor independente mais forte de recuperação miocárdica contrátil no seguimento de 3 meses na análise de regressão multivariada. A curva ROC (Receiver Operating Characteristic) mostrou que um valor de corte da porcentagem de captação total do 99mTc-sestamibi uptake de 72%, foi o melhor preditor da recuperação miocárdica contrátil, com uma sensibilidade de 100% e especificidade de 95.7%. CONCLUSÃO: Em pacientes sem evidência de viabilidade na ecocardiografia de estresse com dobutamina de baixa dose, a porcentagem de captação total do 99mTc-sestamibi prediz, de forma independente, a recuperação miocárdica contrátil após a revascularização coronária.

A Comparison of Radiation Dose Between Standard and 3D Angiography in Congenital Heart Disease

Background: The use of three-dimensional rotational angiography (3D-RA) to assess patients with congenital heart diseases appears to be a promising technique despite the scarce literature available. Objectives: The objective of this study was to describe our initial experience with 3D-RA and to compare its radiation dose to that of standard two-dimensional angiography (2D-SA). Methods: Between September 2011 and April 2012, 18 patients underwent simultaneous 3D-RA and 2D-SA during diagnostic cardiac catheterization. Radiation dose was assessed using the dose-area-product (DAP). Results: The median patient age and weight were 12.5 years and 47.5 Kg, respectively. The median DAP of each 3D-RA acquisition was 1093µGy.m2 and 190µGy.m2 for each 2D-SA acquisition (p<0.01). In patients weighing more than 45Kg (n=7), this difference was attenuated but still significant (1525 µGy.m2 vs.413µGy.m2, p=0.01). No difference was found between one 3D-RA and three 2D-SA (1525µGy.m2 vs.1238 µGy.m2, p = 0.575) in this population. This difference was significantly higher in patients weighing less than 45Kg (n=9) (713µGy.m2 vs.81µGy.m2, P = 0.008), even when comparing one 3D-RA with three 2D-SA (242µGy.m2, respectively, p<0.008). 3D-RA was extremely useful for the assessment of conduits of univentricular hearts, tortuous branches of the pulmonary artery, and aorta relative to 2D-SA acquisitions. Conclusions: The radiation dose of 3D-RA used in our institution was higher than those previously reported in the literature and this difference was more evident in children. This type of assessment is of paramount importance when starting to perform 3D-RA.

Cost-Effectiveness of High, Moderate and Low-Dose Statins in the Prevention of Vascular Events in the Brazilian Public Health System

Background:Statins have proven efficacy in the reduction of cardiovascular events, but the financial impact of its widespread use can be substantial.Objective:To conduct a cost-effectiveness analysis of three statin dosing schemes in the Brazilian Unified National Health System (SUS) perspective.Methods:We developed a Markov model to evaluate the incremental cost-effectiveness ratios (ICERs) of low, intermediate and high intensity dose regimens in secondary and four primary scenarios (5%, 10%, 15% and 20% ten-year risk) of prevention of cardiovascular events. Regimens with expected low-density lipoprotein cholesterol reduction below 30% (e.g. simvastatin 10mg) were considered as low dose; between 30-40%, (atorvastatin 10mg, simvastatin 40mg), intermediate dose; and above 40% (atorvastatin 20-80mg, rosuvastatin 20mg), high-dose statins. Effectiveness data were obtained from a systematic review with 136,000 patients. National data were used to estimate utilities and costs (expressed as International Dollars - Int$). A willingness-to-pay (WTP) threshold equal to the Brazilian gross domestic product per capita (circa Int$11,770) was applied.Results:Low dose was dominated by extension in the primary prevention scenarios. In the five scenarios, the ICER of intermediate dose was below Int$10,000 per QALY. The ICER of the high versus intermediate dose comparison was above Int$27,000 per QALY in all scenarios. In the cost-effectiveness acceptability curves, intermediate dose had a probability above 50% of being cost-effective with ICERs between Int$ 9,000-20,000 per QALY in all scenarios.Conclusions:Considering a reasonable WTP threshold, intermediate dose statin therapy is economically attractive, and should be a priority intervention in prevention of cardiovascular events in Brazil.

Endothelial Effect of Statin Therapy at a High Dose Versus Low Dose Associated with Ezetimibe

Abstract Background: The effect of statins on the endothelial function in humans remains under discussion. Particularly, it is still unclear if the improvement in endothelial function is due to a reduction in LDL-cholesterol or to an arterial pleiotropic effect. Objective: To test the hypothesis that modulation of the endothelial function promoted by statins is primarily mediated by the degree of reduction in LDL-cholesterol, independent of the dose of statin administered. Methods: Randomized clinical trial with two groups of lipid-lowering treatment (16 patients/each) and one placebo group (14 patients). The two active groups were designed to promote a similar degree of reduction in LDL-cholesterol: the first used statin at a high dose (80 mg, simvastatin 80 group) and the second used statin at a low dose (10 mg) associated with ezetimibe (10 mg, simvastatin 10/ezetimibe group) to optimize the hypolipidemic effect. The endothelial function was assessed by flow-mediated vasodilation (FMV) before and 8 weeks after treatment. Results: The decrease in LDL-cholesterol was similar between the groups simvastatin 80 and simvastatin 10/ezetimibe (27% ± 31% and 30% ± 29%, respectively, p = 0.75). The simvastatin 80 group presented an increase in FMV from 8.4% ± 4.3% at baseline to 11% ± 4.2% after 8 weeks (p = 0.02). Similarly, the group simvastatin 10/ezetimibe showed improvement in FMV from 7.3% ± 3.9% to 12% ± 4.4% (p = 0.001). The placebo group showed no variation in LDL-cholesterol level or endothelial function. Conclusion: The improvement in endothelial function with statin seems to depend more on a reduction in LDL-cholesterol levels, independent of the dose of statin administered, than on pleiotropic mechanisms.

Sôbre uma fórmula para o cálculo da dose mais econômica de adubo

The authors discuss a formula for the determination of the most profitable level of fertilization (x*). This formula, presented by CAREY and ROBINSON (1953), can be written as: x*= (1/c) log cx u L10 + (1/c) log wu _______ ___ 1-10 x u t being c the growth factor in Mitscherlich's equation, x u a standard dressing of the nutrient, L 10 the Naeperian logarithm of 10, u the response to the standard dressing, w the unit price of the crop product, and i the unit price of the nutrient. This formula is a modification of one of the formulas of PIMENTEL GOMES (1953). One of its advantages is that is does not depend on A, the theoretical maximum harvest, which is not directly given by experimental data. But another advantage, proved in this. paper, is that the first term on the right hand side K= 1(/c) log cx u L 10 ____________ 1 - 10-cx u is practically independent of c, and approximately equivalent to (1/2) x u. So, we have approximately x* = (1/2) x u + (1/c) log wu . ____ x u t With experimental data we compute z = wu ____ x u t then using tables 1, 2 and 3, we may obtain Y - (1/c) log z and finally x* = (1/2) x u + Y. This is an easy way to determine the most profitable level of fertilization when experimental data on the response u to a dressing x u are available. Tables for the calculation of Y are included, for nitrogen, phosphorus, potash, and manure.
