Authors: Al-Rayes Hannan , Huraib Ghaleb , Julkhuf Saeed , Arfin Misbahul , Tariq Mohammad , Al-Asmari Abdulrahman
Published: May 2016

Apolipoprotein E (APOE) is a glycosylated protein with multiple biological properties. APOE gene polymorphism plays a central role in lipid metabolism and has recently been suggested to regulate inflammation. Our objective is to evaluate whether APOE polymorphism affects susceptibility to SLE. APOE genotyping was performed using ApoE StripAssay™ kit. Results indicated significantly higher frequencies of allele ∊4 and genotype ∊3/∊4 and lower frequencies of allele ∊3 and genotype ∊3/∊3 in SLE patients than controls. APOE ∊2 allele was found in three patients, whereas it was absent in controls. The frequencies of allele ∊4 and genotype ∊3/∊4 were significantly higher in SLE patients with renal involvement and those of alleles ∊2, ∊4 and genotypes ∊2/∊3, ∊3/∊4 were higher in patients with neuropsychiatric symptoms. It is concluded that APOE allele ∊4 is associated with susceptibility risk/clinical manifestations of SLE and ∊2 may increase its severity while ∊3 is protective for SLE in Saudis.

Abstract. Sulphur dioxide (SO2) measurements from the Ozone Monitoring Instrument (OMI) satellite sensor processed with the new Principal Component Analysis (PCA) algorithm were used to detect large point emission sources or clusters of sources. The total of 491 continuously emitting point sources releasing from about 30 kt yr−1 to more than 4000 kt yr−1 of SO2 per year have been identified and grouped by country and by primary source origin: volcanoes (76 sources); power plants (297); smelters (53); and sources related to the oil and gas industry (65). The sources were identified using different methods, including through OMI measurements themselves applied to a new emissions detection algorithm, and their evolution during the 2005–2014 period was traced by estimating annual emissions from each source. For volcanic sources, the study focused on continuous degassing, and emissions from explosive eruptions were excluded. Emissions from degassing volcanic sources were measured, many for the first time, and collectively they account for about 30 % of total SO2 emissions estimated from OMI measurements, but that fraction has increased in recent years given that cumulative global emissions from power plants and smelters are declining while emissions from oil and gas industry remained nearly constant. Anthropogenic emissions from the USA declined by 80 % over the 2005–2014 period as did emissions from western and central Europe, whereas emissions from India nearly doubled, and emissions from other large SO2-emitting regions (South Africa, Russia, Mexico, and the Middle East) remained fairly constant. In total, OMI-based estimates account for about a half of total reported anthropogenic SO2 emissions; the remaining half is likely related to sources emitting less than 30 kt yr−1 and not detected by OMI.

Published: May 2016

Abstract. Evaporation plays important roles in regional water resources management,terrestrial ecological process and regional climate change. This study investigated the abilities of six different soft computing methods, Multi-layer perceptron (MLP), generalized regression neural network (GRNN), fuzzy genetic (FG), least square support vector machine (LSSVM), multivariate adaptive regression spline (MARS), adaptive neuro-fuzzy inference systems with grid partition (ANFIS-GP), and two regression methods, multiple linear regression (MLR) and Stephens and Stewart model (SS) in predicting monthly Ep. Long-term climatic data at eight stations in different climates, air temperature (Ta), solar radiation (Rg), sunshine hours (Hs), relative humidity (RH) and wind speed (Ws) during 1961–2000 are used for model development and validation. The first part of applications focused on testing and comparing the model accuracies using different local input combinations. The results showed that the models have different accuracies in different climates and the MLP model performed superior to the other models in predicting monthly Ep at most stations, while GRNN model performed better in Tibetan Plateau. The accuracies of above models ranked as: MLP, GRNN, LSSVM, FG, ANFIS-GP, MARS and MLR. Generalized models were also developed and tested with data of eight stations. The overall results indicated that the soft computing techniques generally performed better than the regression methods, but MLR and SS models can be more preferred at some climatic zones instead of complex nonlinear models, for example, the BJ, CQ and HK stations.

Lessons Learned in Fifteen Years of Evolution of the Linking and MoT Office of a R&D Public Center
Authors: Vega-González Luis Roberto
Published: May 2016

In this paper it is proposed that similarly with the evolution and maturation of any organization, the Linking and Management of Technology Office (L & MoT) of a public R&D Mexican Centre has been evolved and is in the way to be transformed into a Technology Transfer Office (TTO). Case of fifteen year evolution of the Centro de Ciencias Aplicadas y Desarrollo Tecnológico L & MoT presents empirical evidence to identify the main phases and actions that have been driving this process along this time. Standard results obtained through the years using the L & MoT Management of Technology Model (MoT) are presented. Emphasis is placed in a final section with the lessons obtained from non-standard results coming from unsuccessful negotiations and failed link actions between the Center and some external organizations. Experience has shown that not all negotiations are successful but curiously, the best lessons for the personnel of a technology transfer office are probably derived from these problematic cases.
Can Ethical Business Strategy Influence Consumers’ Buying Behavior and Loyalty: Marks and Spencer PLC?
Authors: Islam Kamrul
Published: May 2016

The project aims to research the impact of ethical business strategy in retail industry. It will primarily focus on one particular aspect of the ethical business strategy, customers’ buying behaviour and loyalty issues. For the purpose of this research a leading retailer, Marks and Spencer will be evaluated, the impact of Ethical Business Strategy (known as Plan A) on its 33.6 million consumers’ base. Literature review suggests ethical business strategy has an impact on consumers and can enable an organisation to achieve sustainable competitive advantages in the long term. A survey was conducted for consumers of Marks and Spencer Simply Food to establish what impact it had on consumer choice. The findings and analysis of survey data highlighted Plan A fails to influence the majority of the consumer’s buying behaviour and loyalty. However it affects between 10% to 12 % consumers that are viewed as ethical consumers by the Business Analyst. As a result of this research, recommendations have been made for Marks and Spencer. As a student researcher in order to meet time constraints and cost, researcher selected to conduct survey in one department of Marks and Spencer, Marks and Spencer Simply Food. The reader will need to take this limitation into account when reading this report, as the outcomes may have been different if various departments were surveyed.

Authors: Cho Yoon J. , Lee Choong H. , Chun Young S. , Rhyu Kee H.
Published: May 2016

Purpose

In this case series, we investigated the outcome of cementless total hip arthroplasty (THA) for advanced hip osteoarthritis in patients with residual poliomyelitis to evaluate its clinical usefulness for these patients.

Methods

11 unilateral cementless primary THA were performed to arthritic hips in patients with residual poliomyelitis. 7 were in paralytic and 4 were in nonparalytic limbs. The mean follow-up duration was 79.9 months. Retrospective clinical evaluations with various scores and radiological evaluations were made.

Results

Harris Hip Score, Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Short-form (SF)-36 physical scales were significantly improved after the surgery. However, UCLA activity score and SF-36 mental scale were not. Because of remaining leg length discrepancies, all but 1 noted a residual limp. In nonparalytic hip, functional acetabular cup inclination during weight bearing significantly increased from installed inclination. Other than 1 case of posterior dislocation, no complications were observed.

Conclusions

Although the overall result itself is excellent, THA for these patients cannot improve limp, physical activity and mental status. Surgeons should be aware of the change of the inclination of acetabular cup during mobilisation, especially for THA in contralateral hip.

Published: May 2016

The study is aimed at examining the vulnerability of some residential neighbourhoods in Calabar to the menace of flooding with a view to determining residential areas of high, medium and low flood risk. Two hypotheses were formulated such as: there is no significant relationship between the magnitude of flood, and the vulnerability of residential neighbourhoods and the elements-at-risk to flood in residential neighbourhoods in Calabar do not vary significantly according to the topography of the area. The major primary data were obtained from the metric measurement of the coverage of flood and the assessment of the numerical value of the residential buildings considered vulnerable to flood within the areas measured. Secondary data were also obtained from the collection of both published and unpublished materials and data on flooded buildings and displaced persons were also obtained from the State Emergency Management Agency (SEMA), Calabar. The data were analyzed using descriptive statistics and hypotheses tested using the regression coefficient of the least square method and scatter grams for prediction. The results of the hypotheses were found to be significant as the magnitude of flood determined the vulnerability of some residential neighbourhoods. Vulnerability was found to be higher in low lying residential neighbourhoods. The study, however, recommends among others, planned and autonomous adaptation responses, flood plain zoning to urban agriculture, landscaping and recreational uses. Proper channelization of Calabar urban drainage system, stringent flood control legislation, and development control measures should be enforced so as to discourage people from building on or near flood-prone areas of Calabar.

We discussed the dynamical complexities of this model using numerical responses, solution curves and phase-space diagrams.
High Order Feedback-Feedforward Iterative Learning Control Scheme with a Variable Forgetting Factor
Authors: Wang Hongbin , Dong Jian , Wang Yueling
Published: May 2016

In this work, we present a new iterative learning control (ILC) scheme for a class of non-linear systems with uncertain and non-repetitive disturbances, in order to achieve perfect tracking by proposing a high order feedback-feedforward ILC algorithm with a variable forgetting factor. The high order feedback-feedforward iterative learning controller can fully apply the previous control data to the system, which allows the system to track expectations more rapidly and precisely. Introducing a variable forgetting factor can weaken the former control output and its variance in the control law, while strengthening the robustness of the ILC. Through rigorous analyses, we demonstrate that uniform convergence of the state tracking error is guaranteed under this new ILC scheme. Simulation examples are also included to demonstrate the feasibility and effectiveness of the proposed learning controls.
Análise do potencial de flexibilidade estrutural: o caso de uma cooperativa de trabalho
Authors: Felype Neis Dyogo , Soares Marison Luiz , Pereira Mauricio Fernandes
Published: May 2016

The article aims to analyze the structure flexibility potential of a Medical Cooperative from the perspective of Dominant Coalition. It is characterized as a qualitative research, with the descriptive objective and delineated by the single case study strategy. The data were collected through semi-structured interviews, document analysis and systematic direct observation. It was found that the environment that the Cooperative operates is dynamic and complex, mainly due to the market being regulated by Government, the entry of new competitors, as well as social, cultural and economic factors that underlie any market. This context tends to require greater flexibility potential of organizations. The structural flexibility is associated with the degree of mechanistic: the more mechanical, less flexible. However, even acting in this context and being set up as a cooperative, research indicates the predominance of mechanistic aspects. The cooperative management model, the size of the organization and the use of the Total Quality Management, are aspects that restrict the potential for structural flexibility of Cooperative.

Published: May 2016

Industries characterized by the distribution of knowledge among its actors have adopted a governance structure based on contractual strategic alliances for a number of organizational activities such as research and development, manufacturing, marketing, distribution and supply. On one hand alliances are fundamental to the performance of these sectors, on the other, there is a 50% rate of failure of these alliances, as its management, demand integration efforts of the activities developed jointly by independent partners is still a major challenge, with impact on coordination costs. Accordingly, with this article, by means of qualitative research and the exploratory case study, we sought to show the importance that the mechanisms of synchronization and its main microfoundations − individuals, processes and estructures − the relational capacity, carry on the good management of contractual strategic alliances.

Published: May 2016

Over the years, technology parks have attracted organizations seeking competitiveness through innovation and technological cooperation. The aim of this study was to investigate the relationship between the competencies contained within a technology park, TECNOPUC, and the competitiveness of the Information Technology (IT) firms located within it. A qualitative exploratory study was conducted involving experts on the topic, the Park managers and managers from seven firms located in the Park. The findings reveal the perception that the brand TECNOPUC and the working environment provided by the Park are the competencies that are more closely related to the competitiveness of the firms located within it. The managers interviewed seem to be in the Park in search of business opportunities with large corporations, focusing their actions on reducing costs in order to achieve greater competitiveness. Rather than developing or selling technology, the priority seems to be selling products and services. Thus, actions aimed at encouraging and promoting research, technological development and innovations, such as the implementation of joint projects, for example, are not prioritized.

Construindo alianças estratégicas para a produção na sétima arte: um estudo multicasos em produtoras cinematográficas brasileiras
Authors: Gonçalves Carlos Alberto , Silva Everton Rodrigues , Lopes Daniel Paulino Teixeira
Published: May 2016

The movie industry is characterized by the ambiguity of being an industrial activity and a symbolic to the national identity. Despite its relevance, there is a literature gap concerning the role of alliances in the national film production. We sought to understand this process through the lens of the industry structure and the resource-based view. This study was qualitative in nature on the basis of a multiple case study approach and semi-structured interviews. The findings showed that, due to the majors’ oligopolistic domain, the national industry inherited the North American pattern for revenue-sharing among participants in the production chain. However, the United States market structure is based in both vertical integration and strong ties between the movie industry and the television industry. Analyzing the Brazilian movie industry, government resignation from investing in production, reduced film lifecycles, and few projects funded privately (via incentive laws), competition between productions is fierce. We found not only that alliances are essential to the functioning of the industry (resource complementarity), but also that producers are strongly dependent to other elements in the movie value system – particularly due to power asymmetries created by the industry structure. Complementarity and dependency go hand in hand.

Published: May 2016

This study aimed to identify, within the framework of a public organization, indicators allowing an assessment of the quality of outsourced service maintenance of layout according to the perspectives of users, of contract fiscals and of the responsible for service providers. Through the statistical technique of structural equations modeling, the definition of constructs directly relevant to the measurement of quality of service of maintenance of layout has been obtained. On the basis of the results of four surveys (a quantitative one with service users and three qualitative, each of them with each segment: users, fiscals and service providers) it was possible to compare the rankings of the aspects that lead to perceived quality of the services in accordance with the three segments of interest in this work. The main indicators and their assessments may be considered by the company focused in this study as items in the drawing up of contracts between suppliers and contracting part and as references in monitoring the provision of maintenance of layout.

This study aimed to verify the criteria used by the funds Venture Capital / Private Equity in investment decisions. For such, held a multicase study at three managers of investment funds. Data collection was conducted through questionnaires and interviews (structured and semi-structured) from September 2010 to December 2010. It was observed that the managers of the cases studied using the following criteria as having the greatest impact on the evaluation process: the management team and their skills, product-market fund and criteria, these criteria mentioned by Muzyka et al. (1996). About this result, one must note two aspects: (i) the preoccupation with the management capacity is considered by managers as the most relevant criterion for maximizing the chances of projects being implemented, and (ii) the criteria of the fund, unlike that found in Pottery search et al. (1996), there are subsidiary, which probably stems from the expertise and / or regionalization of the investment portfolio, as well as aspects of Brazilian regulations that establish limits for target companies.

The objective of the research is to examine the existence of social disclosure practices in companies that compose the ISE under the approach of isomorphism, in other words, we compared the disclosure or not a particular social practice by major companies comprising the ISE are also disclosed by other companies. Adopted the metric proposed by Vieira (2006) to measure social disclosure, the metric is composed of 16 disclosure items relating to social information to be disclosed in the Annual Reports of the companies. The group of "major companies" was composed by the Bank Brazil SA (1st Place) and Banco Bradesco SA (2nd Place). The sample was composed of 37 public companies listed on the ISE in version 2010/2011. The results provide subsidies to non-rejection of the hypothesis that the larger companies will be followed by other companies as the disclosure of social information.
The Power Brokers
Authors: Lambert Jeremiah D.
Published: May 2016

How the interplay between government regulation and the private sector has shaped the electric industry, from its nineteenth-century origins to twenty-first-century market restructuring.

For more than a century, the interplay between private, investor-owned electric utilities and government regulators has shaped the electric power industry in the United States. Provision of an essential service to largely dependent consumers invited government oversight and ever more sophisticated market intervention. The industry has sought to manage, co-opt, and profit from government regulation. In The Power Brokers, Jeremiah Lambert maps this complex interaction from the late nineteenth century to the present day.

Lambert's narrative focuses on seven important industry players: Samuel Insull, the principal industry architect and prime mover; David Lilienthal, chairman of the Tennessee Valley Authority (TVA), who waged a desperate battle for market share; Don Hodel, who presided over the Bonneville Power Administration (BPA) in its failed attempt to launch a multi-plant nuclear power program; Paul Joskow, the MIT economics professor who foresaw a restructured and competitive electric power industry; Enron's Ken Lay, master of political influence and market-rigging; Amory Lovins, a pioneer proponent of sustainable power; and Jim Rogers, head of Duke Energy, a giant coal-fired utility threatened by decarbonization. Lambert tells how Insull built an empire in a regulatory vacuum, and how the government entered the electricity marketplace by making cheap hydropower available through the TVA. He describes the failed overreach of the BPA, the rise of competitive electricity markets, Enron's market manipulation, Lovins's radical vision of a decentralized industry powered by renewables, and Rogers's remarkable effort to influence cap-and-trade legislation. Lambert shows how the power industry has sought to use regulatory change to preserve or secure market dominance and how rogue players have gamed imperfectly restructured electricity markets. Integrating regulation and competition in this industry has proven a difficult experiment.
Osteopathic Manipulative Treatment Technique Scores on the COMLEX-USA Level 2-PE: An Analysis of the Skills Assessed
Authors: Smith Larissa L. , Xu Wei , Sandella Jeanne M. , Dowling Dennis J.
Published: May 2016

Context: The National Board of Osteopathic Medical Examiners uses the Osteopathic Manipulative Treatment (OMT) Global Rating Tool to score candidate performance in OMT during standardized patient encounters. To the authors’ knowledge, no validity research has been published on the underlying constructs measured by this instrument to date.

Objective: To evaluate whether the OMT Global Rating Tool measures 1 holistic skill or multiple skill sets.

Methods: Structural equation models were fit to data from first-time test-takers who took the Comprehensive Osteopathic Medical Licensing Examination-USA Level 2-Performance Evaluation (COMLEX-USA Level 2-PE) between July 7, 2014, and April 30, 2015. Two theoretical models were evaluated: a model that posited a single underlying skill set, and a model that posited 2 related but distinct skill sets.

Results: The 1-factor and 2-factor models were fit to data from 4673 third- and fourth-year osteopathic medical students. Fit statistics indicated that the data were best fit by a model representing 2 factors: pre– and post–OMT technique assessment and OMT technique (r=0.47).

Conclusion: The OMT Global Rating Tool seems to measure 2 distinct but related skills. Although the results of this study are applicable to broad populations and cannot be used to provide skill-specific subscores, it might be helpful to remediation efforts to target pre– and post–OMT technique assessments and OMT techniques as distinct areas for intervention.

In this letter, we inserted a low dielectric constant (low-k) or high dielectric constant (high-k) material as a switching layer in indium–tin-oxide-based resistive random-access memory. After measuring the two samples, we found that the low-k material device has very low operating voltages (−80 and 110 mV for SET and RESET operations, respectively). Current fitting results were then used with the COMSOL software package to simulate electric field distribution in the layers. After combining the electrical measurement results with simulations, a conduction model was proposed to explain resistance switching behaviors in the two structures.
Mercado de Trabalho e Empregabilidade sob a Lógica do Capital: Representações Sociais do Secretário Executivo no Amapá
Authors: Lobato Marília Gabriela Silva , Caldas Yurgel Pantoja , Costa Arley José Silveira
Published: May 2016

O sistema capitalista, as mudanças no mundo do trabalho e a ideologia da empregabilidade interferem nas representações sobre a condição social e laboral. Assim, este trabalho analisou as representações sociais do Secretário Executivo sobre sua profissão e empregabilidade no mercado de trabalho do Amapá. Quatro bacharéis em Secretariado Executivo empregados, quatro desempregados e quatro acadêmicos de Secretariado Executivo da UNIFAP foram entrevistados. Os discursos foram analisados segundo a teoria das representações sociais. Os secretários caracterizaram seu mercado de trabalho como limitante, com reduzidas remuneração e vagas. A profissão é vista como precarizada, repleta de estigmas negativos e com baixo reconhecimento. Esse quadro é acentuado, embora não produzido, pelas condições econômicas do Amapá que se configuram por reduzido número de empresas, forte presença estatal e políticas públicas voltadas aos grandes projetos que não capilarizam o desenvolvimento. As representações apresentaram a adequação ao mercado flexível e a qualificação permanente como mantenedoras da empregabilidade, evidenciando a influência ideológica e técnica do sistema capitalista. Contraposições individuais ao discurso neoliberal surgem como crítica ao estereótipo da profissão, a precariedade do trabalho e a condição socioeconômica no Amapá que interferem no desenvolvimento da região e na demanda pela força de trabalho do Secretário Executivo. Entretanto, modificar tais representações demanda esforços coletivos, e não apenas individuais, por alterações no contexto da profissão, na forma exploradora como o capital rege o mundo do trabalho e na elaboração de políticas públicas que ampliem o desenvolvimento da região e melhorem a qualidade de vida.

Published: May 2016

Objectives

To evaluate the diagnostic value of spectral Doppler sonography in women with thyroid dysfunction during the first postpartum year.

Methods

This prospective observational clinical study included 83 consecutive untreated women: 32 with hyperthyroid postpartum thyroiditis, 32 with hypothyroid postpartum thyroiditis, and 19 with Graves disease, which first appeared within 12 months after delivery. Thyrotropin, free thyroid hormones, thyroid peroxidase antibodies, thyroglobulin antibodies, and thyrotropin receptor antibodies were measured. With a 7.5‐MHz linear transducer, we measured the thyroid volume and peak systolic velocity (PSV) at the level of intrathyroid arteries.

Results

Hyperthyroid postpartum thyroiditis appeared significantly earlier (mean ± SD, 4.4 ± 1.9 months after delivery) than hypothyroid postpartum thyroiditis (6.5 ± 2.1 months) and Graves disease (7.2 ± 2.7 months; P< .001). The thyroid volume in hyperthyroid postpartum thyroiditis (9.7 ± 6.3 mL) was significantly lower than in hypothyroid postpartum thyroiditis (14.7 ± 10.2 mL; P = .030) and Graves disease (19.4 ± 10.2 mL; P< .001). The PSV in hyperthyroid postpartum thyroiditis (9.4 ± 3.4 cm/s) was significantly lower than in hypothyroid postpartum thyroiditis (14.4 ± 3.9 cm/s; P < .001) and Graves disease (19.8 ± 7.0 cm/s; P < .001). With a cutoff level of 15 cm/s, the sensitivity and specificity of the PSV as a predictor of the correct diagnosis in hyperthyroid postpartum women were 94.7% and 96.8%, respectively. A multinomial logistic regression revealed PSV and the time after delivery at which the disorders presented as independent predictors of the differentiation between hyperthyroid postpartum thyroiditis and Graves disease (P = .003; P = .022).

Conclusions

Spectral Doppler sonography was shown to be a useful and accurate method for thyroid dysfunction evaluation during the postpartum period.
Assessing the professional competencies of correctional executives' and senior‐level leaders'
Authors: Harper D.S.
Published: May 2016

Background

This non‐experimental, quantitative study, examines and validates the National Institute of Corrections' executive and senior‐level leadership competencies and predetermined experiences that should lead to identifying the right correctional leadership development. From the solicitation of correctional executives' and senior‐level leaders' own perceptions.

Methods

Correctional Executives (n = 90) completed a researcher designed measure of leaders perceptions of utilization of NIC competencies and experiences.

Results

On‐the‐job training and progressive job assignment (serving in a role prior to appointment to a long term or permanent assignment) emerged as favorable ways for developing correctional leadership competencies. Additionally, the results of this study provided evidence supporting some highly predictive dependent variables as beneficial for first time executives in corrections and for effective correctional executive leadership.

Conclusions

The results of the study does not support separating leadership profiles for correctional executives and senior‐level leaders. Study showed that leaders agreed on certain competencies when combining leadership experiences. Finally the biological characteristic ethnicities and organizational size identified as predictable factors for the utilization competencies.
