An Approach to Represent and Communicate Product or System Design Ideas at the Fuzzy-Front End of the Design Process
Authors: Opiyo Eliab
Published: January 2016

The primary challenge underscored and dealt with was how to represent the product’s or system’s use environment and processes and to communicate ideas and envisaged use contexts effectively at the fuzzy-front early stages of the design process. The work focused specifically on complex products or systems with physical, software and/or cyber components, and the question was how to represent, e.g., the operations of the product or system and the interactions between the user and the product or system betimes in the period between when an opportunity for a new product or system is first considered, and when the idea is judged to be ready to enter formal development. Several approaches are currently being used to express and to communicate ideas at the conceptualization, embodiment, and detail design stages of the design process, but none of them address the challenge described above. We therefore adapted and extended the abstract prototyping concept to allow for total representation of ideas, as well as of use environments and processes early on. Extended abstract prototyping (Ext-AP) entails using combinations of low and high-fidelity prototyping techniques to create cognitive virtual representations, which represent and help designers to express ideas and use contexts—namely, what complex product or system would be like, and how its users would interact with it. Real-world product development case studies have been used to demonstrate how the Ext-AP technique can be put into practice. One of the main observations from the application case studies is that the Ext-AP technique enabled the subjects to express ideas and use contexts more effectively early on. In addition, the extended abstract prototypes (Ext-APs) offered a low cost, yet effective solution for expressing ideas, representing concepts and using contexts, and allowed the subjects to think divergently, make associations, easily and quickly construct, combine, and evaluate alternatives, and work together on multiple ideas simultaneously.
APPLICATION OF COLLOCATION BEM FOR AXISYMMETRIC TRANSMISSION PROBLEMS IN ELECTRO- AND MAGNETOSTATICS
Authors: Lavrova Olga , Polevikov Viktor
Published: January 2016

This paper considers the numerical solution of boundary integral equations for an exterior transmission problem in a three-dimensional axisymmetric domain. The resulting potential problem is formulated in a meridian plane as the second kind integral equation for a boundary potential and the first kind integral equation for a boundary flux. The numerical method is an axisymmetric collocation with equal order approximations of the boundary unknowns on a polygonal boundary. The complete elliptic integrals of the kernels are approximated by polynomials. An asymptotic kernels behavior is analyzed for accurate numerical evaluation of integrals. A piecewise-constant midpoint collocation and a piecewise-linear nodal collocation on a circular arc and on its polygonal interpolation are used for test computations on uniform meshes. We analyze empirically the influence of the polygonal boundary interpolation to the accuracy and the convergence of the presented method. We have found that the polygonal boundary interpolation does not change the convergence behavior on the smooth boundary for the piecewise-constant and the piecewise-linear collocation.
ON STRONG CONVERGENCE OF HALPERN’S METHOD FOR QUASI-NONEXPANSIVE MAPPINGS IN HILBERT SPACES
Authors: Falset Jesus Garcia , Llorens-Fuster Enrique , Marino Giuseppe , Rugiano Angela
Published: January 2016

In this paper, we introduce a Halpern’s type method to approximate common fixed points of a nonexpansive mapping T and a strongly quasi-nonexpansive mappings S, defined in a Hilbert space, such that I − S is demiclosed at 0. The result shows as the same algorithm converges to different points, depending on the assumptions of the coefficients. Moreover, a numerical example of our iterative scheme is given.
EXTENDING THE BEM FOR ELASTIC CONTACT PROBLEMS BEYOND THE HALF-SPACE APPROACH
Authors: Zhao Jing , Vollebregt Edwin A.H. , Oosterlee Cornelis W.
Published: January 2016

The boundary element method (BEM) is widely used in fast numerical solvers for concentrated elastic contact problems arising from the wheel-rail contact in the railway industry. In this paper we extend the range of applicability of BEM by computing the influence coefficients (ICs) numerically. These ICs represent the Green’s function of the problem, i.e. the surface deformation due to unit loads. They are not analytically available when the half-space is invalid, for instance in conformal contact. An elastic model is proposed to compute these ICs numerically, by the finite element method (FEM). We present a detailed investigation to find proper strategies of FEM meshing and element types, considering accuracy and computational cost. Moreover, the effects of computed ICs to contact solutions are examined for a Cattaneo shift contact problem. The work in this paper provides a guidance to study fast solvers for the conformal contact.

Published: January 2016

The survivorship of total hip arthroplasty in younger patients is dependent on the wear characteristics of the bearing surfaces. Long-term results with conventional polyethylene in young patients show a high failure rate. This study assessed the long-term results of a first-generation annealed highly cross-linked polyethylene (HCLPE) in uncemented total hip arthroplasty in young, active patients. Between 1999 and 2003, 112 total hip arthroplasty procedures performed in 91 patients with an average University of California Los Angeles activity score of 8 and mean age of 53 years (range, 24–65 years) were included from a prospective database. In all patients, a 28-mm metal femoral head on annealed HCLPE (Crossfire; Stryker, Mahwah, New Jersey) was used. At minimum 10-year follow-up (11.5±0.94 years), Kaplan-Meier survivorship was 97% for all failures (1 periprosthetic infection and 1 late dislocation) and 100% for mechanical failure (no revisions for osteolysis or loosening). This study showed low revision rates for wear-related failure and superior survivorship in young, active patients. Oxidation causing failure of the locking mechanism has not been a problem with Crossfire for up to 10 years. [

Public Demand Aggregation as a Means of Bridging the ICT Gender Divide
Authors: Williams Idongesit , Kwofie Benjamin , Sidii Fauziatu Salifu
Published: January 2016

More men use ICTs than women globally. This is not because there are more men than women globally. Rather, it is because of social, economic and cultural challenges that work against the adoption of ICTs by women. In this chapter, public demand aggregation of ICT content is promoted as a means of bridging the ICT gender gap. The argument presented here is; the promotion of useful e-government service(s) in a country will enable equal adoption of ICTs by both men and Women. The argument for content is inspired by the examples proposed in this chapter as well as a synthesis of results from the Ghana Wireless Project and a research visit to Jaribu and Kerege in Tanzania. This chapter concludes, that the adoption of mandatory national e-government initiatives will result in more women identifying other uses of ICTs in other areas of their lives, spurring sustainable adoption of ICTs.
ICT Is Not Gender Blind
Authors: Ibrahim Adamkolo Mohammed , Adamu Mohammed Alhaji
Published: January 2016

This chapter critically reviewed literature on gender disparity associated with access and usage of ICT, focusing on the less developed world, especially Sub-Saharan Africa. The authors used relevant online literature sourced from research databases such as Google Scholar, Elsevier and Wiley Online Library. With the aid of graphical illustrations, the chapter aligned its argument with some critical global research findings regarding gender-based mobile phone and Internet usage and the concept of ICT and gender. The chapter concluded that ICT gender gap negatively affects the socio-economic development of women, and recommended that ICTs manufacturers should integrate gender-balanced software and hardware right at the time of production of the technologies.

Published: January 2016

As the popularity and acceptance of agile software development methodologies increases, the need to integrate usability engineering in the design and development processes is imperative. While, agile the focus is on technical and functional requirements not on end-user interaction, usability is usually only dealt with on the side. Combining this two in practice will go a long way in development of better product. Since the success and acceptance of software product depends not only on the technologies used but how well it integrates user-oriented methods. Therefore, this chapter puts together works on how usability engineering has been integrated with agile processes.
mHealth
Authors: Waegemann C. Peter
Published: January 2016

mHealth systems have been maturing since 1995, yet there remains no common definition. The widest definition encompasses not only mobile devices and digital communication systems, but also the multitudes of apps and add-ons for those mobile devices and systems. Accordingly, mHealth is an indicator of emerging communication-based healthcare and an enabler of participatory health. mHealth implementation and user acceptance vary by geographical region. In the most advanced regions, mobile devices and new communication systems lead to disruptive changes that improve the quality of care and reduce healthcare costs. At the same time, providers and public authorities are challenged with designing and implementing mHealth policies and security measures. Ultimately, mHealth will change healthcare policies and procedures, the structures of healthcare, and the roles of patients and healthcare professionals.

Authors: Chakraborty Chinmay , Gupta Bharat , Ghosh Soumya K.
Published: January 2016

Telemedicine can be defined as the delivery of health care and sharing of medical information at a distance using telecommunication platforms. This chapter describes the implementation of a mobile telemedicine system for patient's chronic wound (CW) monitoring using a smartphone. The system proved to be quick and reliable for providing health care at door step. The tele-wound technology network (TWTN) framework in telemedicine systems using smartphones for remote wound monitoring has been proposed. This framework is effective for both rural as well as urban people; it gives good performance in terms of wound monitoring and advanced diagnosis. The main objective of this work is to design and develop a TWTN system model that can acquire, process and monitor CW related problems with using a low cost smartphone to increase the overall performance of the system. Specifically, the TWTN system is developed for biomedical information like CW processing to monitor important patient information inexpensively and accurately.
From Telecytology to Mobile Cytopathology
Authors: Pouliakis Abraham , Archondakis Stavros , Margari Niki , Karakitsos Petros
Published: January 2016

Cytopathology is a popular discipline since George Papanicolaou proposed the famous test pap about 60 years ago. Today modern cytopathology laboratories still use the microscope as the primary diagnostic device and additionally they host modalities performing medical tests and exchange data via networks and have imaging systems producing pictures and virtual slides; the volume of produced data nowadays is enormous. Simultaneously mobile phones and tablets have evolved; their capabilities compete desktop computers and have the advantage of being always connected and at the side of users. Despite there are rather limited applications relevant to cytopathology for the mobile device, there is potential for uses in numerous activities of the cytopathology laboratory, including and not limited to: training, reporting, diagnosis and consultation, laboratory management, whole slide imaging, interactions between patient-doctor, doctor-doctor and within the laboratory personnel, quality control and assurance. Mobile devices can offer important benefits to the modern cytopathology laboratory.
Lower is better: ENHANCE affair
Authors: Scardi Sabino , Umari Paolo , D’Agata Bianca Maria
Published: January 2016

Ezetimibe lowers the intestinal absorption of cholesterol, being complementary to the effects of statin. To check its efficacy in lowering the carotid intima-media thickness, in 2002 a multicenter international trial called ENHANCE was started, in order to assess by ultrasound the regression of atherosclerotic plaques. The protocol tested the use of simvastatin 80 mg + placebo versus simvastatin 80 mg + ezetimibe 10 mg in 720 randomized patients. Both drugs were well tolerated. Combination therapy was associated with a larger reduction in LDL cholesterol, but there were no differences in the intima-media thickness measured at three sites in the carotid arteries, nor differences in cardiovascular events between the two groups in the trial. These results provoked disappointment of sponsors (Merck, Schering Plough) who, although the results of the trial were available since march 2007, delayed official communication of about 18 months. This led to speculations and rumors among media, American Government, cardiologic scientific associations, and consequences in the Ezetimibe market and at Wall Street. In particular, the American College of Cardiology didn’t accept the communication of ENHANCE results to the Late Breaking Trial Session of the Chicago congress, diverting it to another secondary forum. In conclusion, the experience of the ENHANCE trial suggests to pharmaceutical companies, researchers, clinicians, scientific companies and media a deep meditation in order to avoid in the future similar problems in the management of results of medical research.

Published: January 2016

Chlamydia Pneumoniae (CP) infection is strongly associated with coronary artery disease, as well as with atherosclerosis of the carotid and peripheral arteries. However, the role of CP in the pathogenesis of aortic disease remains controversial. Our present experience suggests no correlation between a current infection with C. pneumoniae and acute aortic dissection. Well-designed large prospective studies are needed in order to clarify the pathophysiologic role of CP infection in acute and chronic aortic disease.
Assessment of plasma homocysteine levels in shift healthcare workers
Authors: Copertaro Alfredo , Bracci Massimo , Barbaresi Mariella
Published: January 2016

Background. Previous studies have indicated an association between shift work and cardiovascular disease. Increased plasma homocysteine levels has been proposed as a cardiovascular risk factor independent of other conventional risk factors. Aims. Our aim is to verify the usefulness of plasma homocysteine as a screening test to prevent cardiovascular diseases in shift workers. Methods. Thirty rotating shift nurses and 28 daytime nurses have been submitted during 18 months to regular taking of arterial pressure and body weight. Venous blood was drawn to measure glycaemia, triglycerides, plasma cortisol level, HDL cholesterol, blood cell count, alanine-aminotransferase, aspartate- aminotransferasi, γ-GT, and plasma homocysteine. Results. No increase in average plasma homocysteine in rotating shift nurses, nor a higher frequency in hyperomocisteinemia than in daytime workers was found. A significant difference was observed in body weight and systolic blood pressure (p<0.05), which resulted higher in rotating shift workers than in daytime workers. A significant increase was observed in alanine-aminotransferase (ALT) among shift workers (p<0.05). Conclusions. Plasma homocysteine measurement should not be employed as a screening test for the prevention of cardiovascular disease in rotating shift workers.

Published: January 2016

Socioeconomic position (SEP) is an important risk factor for malaria, but there is no consensus on how to measure SEP in malaria studies. We evaluated the relative strength of four indicators of SEP in predicting malaria risk in Nagongera, Uganda. A total of 318 children resident in 100 households were followed for 36 months to measure parasite prevalence routinely every 3 months and malaria incidence by passive case detection. Household SEP was determined using: 1) two wealth indices, 2) income, 3) occupation, and 4) education. Wealth Index I (reference) included only asset ownership variables. Wealth Index II additionally included food security and house construction variables, which may directly affect malaria. In multivariate analysis, only Wealth Index II and income were associated with the human biting rate, only Wealth Indices I and II were associated with parasite prevalence, and only caregiver's education was associated with malaria incidence. This is the first evaluation of metrics beyond wealth and consumption indices for measuring the association between SEP and malaria. The wealth index still predicted malaria risk after excluding variables directly associated with malaria, but the strength of association was lower. In this setting, wealth indices, income, and education were stronger predictors of socioeconomic differences in malaria risk than occupation.

Reflexiones y representaciones del exilio: de El canto del peregrino (1999) a "El sefardí romántico" (2005)
Authors: Rico Alicia
Published: January 2016

El exilio es un tema recurrente en la obra de Angelina Muñiz-Huberman, miembro del llamado grupo hispanomexicano. La visión del exilio en su obra incluye no solo el exilio republicano sino también el del pueblo judío. Por eso, diferentes Diásporas históricas se superponen enriqueciendo el significado de la experiencia. En su ensayo El canto del peregrino: hacia una poética del exilio (1999) desarrolla sus pensamientos sobre el exilio y analiza numerosos trabajos de autores exiliados (judíos y republicanos españoles) centrándose en como cada uno reflejó la vivencia del exilio en su trabajo.En mi opinión, las ideas desarrolladas en el ensayo se pueden encontrar en su novela El sefardí romántico: la azarosa vida de Mateo Alemán II (2005). El título de la novela establece una conexión directa con la novela picaresca y la vida judía aludiendo al autor converso de Guzmán de Alfarache (1599-1604). Siguiendo el patrón establecido por la novela picaresca clásica, el protagonista de Muñiz-Huberman viaja por España y Europa denunciando la intolerancia que llevó a la Guerra Civil española y a la II Guerra Mundial. Las circunstancias lo llevan al exilio en México, como en el caso de Mateo Alemán. Según la teoría de Ulrich Wicks, pícaros y exiliados tienen mucho en común en su búsqueda continua de libertad, libertad que el exiliado puede encontrar solo en el idioma, como expone Muñiz-Huberman en su ensayo.
El personaje femenino y la libertad temporal en tres novelas históricas de Angelina Muñiz: "Morada interior" (1972), "El Mercader de Tudela" (1995) y "La Burladora de Toledo" (2008)
Authors: Serlet Florien , Houvenghel Eugenia Helena
Published: January 2016

En este trabajo, analizaremos cómo Muñiz representa el exilio en sus novelas históricas a través del uso del tiempo y, más precisamente, cómo la autora privilegia protagonistas femeninas para vehicular sus particulares visiones acerca del tiempo y de la historia en sus obras. Y es que la autora continuamente juega con las fronteras temporales, al crear personajes capaces de moverse libremente entre el pasado remoto y el siglo XX. Así, pretendemos ofrecer una nueva visión acerca de la manera de que esta escritora aprovecha las libertades temporales de la nueva novela histórica como una manera de vivir –y revivir– el exilio a través de personajes femeninos.
Escribir desde el umbral: exilio y literatura en "El canto del peregrino" (1999) de Angelina Muñiz
Authors: Vandeboch Dagmar
Published: January 2016

Este trabajo analiza la relación entre exilio y literatura en el libro de ensayos El canto del peregrino de la escritora hispanomexicana Angelina Muñiz-Huberman, libro en que la autora se propone esbozar una poética del exilio. La relación entre exilio y literatura se presenta de entrada en términos de identidad: el exilio se define como “forma literaria” y la obra tiende a privilegiar una concepción metafórica del exilio sobre enfoques ‘meramente’ históricos o referenciales. Más en particular, se examinará el modo en que la autora se construye una identidad de ‘escritora exiliada’ basada en la asociación estrecha de exilio y literatura, por una parte, y en la conceptualización del exilio como ‘hogar’ o ‘morada’, por otra parte. En segundo lugar, se estudia el impacto discursivo de la tensión entre esta conceptualización literaria y metafórica del exilio y la propia experiencia exílica de la autora. Un breve análisis de la voz enunciativa de la ensayista y de su práctica de la escritura ensayística permitirá estudiar cómo la autora da forma a su conceptualización intrínsecamente compleja y paradójica del exilio.

El presente artículo trata de ofrecer una lectura estética y política de la Antología de la poesía hispanoamericana que publicara Leopoldo Panero entre 1944 y 1945 bajo protección gubernamental. Para ello se parte de la particular biografía del escritor astorgano, su relación en los años treinta con los poetas hispanoamericanos –especialmente Vallejo y Neruda– y su gira por América ya como supuesto prohombre del régimen franquista en 1949 y 1954. La lectura sistemática de sus prólogos y selección de poetas revela la particular visión de Panero sobre Hispanoamérica, mediatizada por el concepto imperial de Falange pero formulada bajo su propia visión de lo que la lírica americana representa para la lengua castellana. Se sostiene así en estas líneas la tesis de que los postulados de Panero representan, a pesar de todo, una opción mucho más compleja de lo que se suele considerar.
Playback Theatre: the art of being oneself. A tool for empowerment and real change for individuals and communities
Authors: Aimo Maria Elena
Published: January 2016

This article presents the application of a theatrical technique—Playback Theatre, which was developed in the United States during the 1970s—to social intervention, as a narrative and listening space that confers value and dignity upon the person and the unique and distinct individual experiences that facilitate their social and relational integration. This art of being oneself, as the author states, uses the oral tradition and spontaneous and creative communication of psychodrama and combines them with theatrical expression. This technique has been shown to be pertinent to both community social work and support groups for persons in problematic situations. The aim of this is to celebrate some specific moment of their lives, as individuals or as a community, and to define strategies for improving living conditions or resolving or alleviating conflicts. It is also used to assess the achievements of the proposed objectives, to strengthen the motivation to change and to transform existing relationships into collaborative ones. This is possible not only owing to the participation of persons, but also to the assumption of different roles that can permit the overcoming of certain traumatic events.In addition to support groups, it is used for the training and supervision of social work professionals. The theatrical technique in question allows them to assume roles as diverse as narrator, audience or actor, whether simultaneously or successively. Taking the role of «performer» or guide to the theatrical action requires prior preparation in order for the group of participants to be able to pool their individualities and their emotions and reflect on them. The participatory methodology that Playback Theatre proposes is important in community social work and is posed in a new and transformative key.
Selection Determinants in College Students’ Financial Tools

Published: January 2016

Recently, considerable concern has arisen over the complex financial markets, which are inclined to require more individual responsibility. Accordingly, students have to bear more responsibility for their financial management. Nevertheless, in a sluggish economy with high unemployment, the commercial events during the last decade have rendered the transition into financial independence more challenging for social freshmen. In addition, some statistical information has revealed the negative outgrowth that occurred in the wake of student loans and the reduction of beginning salaries. Given the aforementioned hidden risks of finance and the importance of money management, we thus endeavored to investigate the factors students consider when choosing financial tools. For the sake of providing students with information for reference, we delivered a similar questionnaire to professionals in the field. We used the received data to examine the gap between experts’ views and students’ perceptions and then inferred possible reasons for the comparison results.The AHP serves as the chief instrument for calculating relative importance and weighting the significance of the factors. We sent the questionnaires to 140 college students at National Chiayi University and 20 professionals in the financial field and 20 professionals in financial field. The general results indicate that opinions differ among individual students, and opinions of students are rather different from those of the experts; thus, we propose that financial institutions should take different opinions into consideration when designing their financial products.

The current study aimed to test and validate a proposed model of the impact of the administrative leadership on customer satisfaction. This model included an external factor which is the administrative leadership, and an internal factor which is the customer satisfaction. The study also aimed to determine the role of human resource training as a mediating factor between the administrative leadership and customer satisfaction. For achieving these research objectives, the study used a quantitative approach to analyzing the data through the use of the structural equation modeling (SEM-AMOS) to test the validity of the proposed research model. The study achieved several results, the most important of which was that the administrative leadership had a positive impact on customer satisfaction. The study also provided evidence of the positive impact of the administrative leadership on customer satisfaction through its positive impact on the training of human resources, which was used as a mediating factor.

The Impact of Farm Forestry on Poverty alleviation and Food Security in Uganda

Published: January 2016

To address the problem of high rural poverty and food insecurity, government and international donors have funded on-farm plantation forestry projects as one of the tools for improving the welfare of rural communities. In the wake of climate change, on-farm plantation forestry has evolved to include carbon forestry, with the dual purpose of sequestering carbon and improving rural livelihoods. However, there is a dearth of empirical evidence regarding whether and under what conditions on-farm plantation forestry can deliver favorable livelihood outcomes.
Therefore, Propensity Score Matching (PSM) and endogenous switching regression models were used to estimate the average treatment effects of adopting eucalyptus and carbon forestry woodlots (under the planvivo system) on consumption expenditure per adult equivalent and daily calorie acquisition per adult equivalent. PSM and switching regression results consistently indicated that adoption of eucalyptus woodlots increased consumption expenditure by 32 and 28.3% respectively. PSM and switching regression results also indicated that adoption of eucalyptus woodlots increased calorie acquisition per adult equivalent by 36 and 13.1% respectively. Results also indicated that adoption of carbon forestry increased calorie acquisition per adult equivalent by between 22 and 26.9% but the impact on consumption expenditure per adult equivalent was mixed. The findings of this study provide empirical evidence that adoption of on-farm eucalyptus woodlots is an important pathway for smallholder farmers to escape poverty and improve food security. Similarly, adoption of carbon forestry woodlots under the planvivo system can improve food security. However, previous on-farm plantation forestry projects were not well targeted to the poor households.

Comment un artiste est-il amené à être produit par John Zorn sur Tzadik ? De quelle manière se déroulent les différentes étapes de production et réalisation de son album ? Quel regard porte-t-il, à travers sa propre expérience, sur le slogan de la maison de disques : « What you hear on Tzadik is the artist’s vision undiluted » ? Pour répondre à ces quelques interrogations, nous avons enquêté auprès de sept musiciens français qui ont publié un ou plusieurs albums sur Tzadik : Jacques Coursil, Maxime Delporte (Stabat Akish), David Konopnicki (AutorYno), Pierre-Yves Macé, Guillaume Perret (Electric Epic), Frédéric Petitprez (Artichaut Orkestra) et Yves Weyh (Zakarya).
