A pesar de todo, ser solidarios
Authors: Gámez Gutiérrez Jorge
Published: May 2018

Ante la situación de desempleo y sus nocivas consecuencias de orden individual y grupal se han ideado muchas propuestas, entre ellas el cooperativismo como opción digna de generación de ocupación e ingresos. Las quejas constantes de los empresarios tradicionales se refieren a las complejidades del régimen laboral colombiano; para salvar los obstáculos el sector solidario ofrece alternativas para los colombianos, en especial profesionales, con formas de organización que mejoran las condiciones para el trabajador y lo convierten en dueño de medios de producción, con formas de organización de capital mediante la asociación y la aparición de propietarios que suponen nuevas regulaciones a fin de facilitar su inclusión en la economía formal, llamadas Cooperativas de Trabajo Asociado (CTA). Se debe abordar el análisis de la brecha entre teoría y práctica del sector solidario, ya que mientras sus postulados dan principal importancia al trabajador como gestor en la práctica las quejas de los profesionales, se refieren a que hay un crecimiento acelerado en el número de CTA que están contratando a las personas como trabajadores y no como asociados, evaden los pagos como gestores y los asimilan a la legislación laboral común, no se crean las CTA por iniciativa de trabajadores sino por sugerencia de las empresas para que presten sus servicios como outsourcing y evaden sus obligaciones laborales. Esta figura asociativa, sin las fisuras que se le atribuyen, sería una muy buena opción ante el desempleo de los profesionales colombianos.

Published: May 2018

Este artigo analisa as representações sociais e as práticas estratégicas de gestores de videolocadoras em relação às tensões relacionais micro/macro que caracterizam o declínio dessas organizações. A partir da perspectiva da estratégia como prática, a pesquisa foi conduzida pela abordagem qualitativa. Para a coleta de dados foram utilizadas a técnica de entrevista e uma técnica projetiva com proprietários das videolocadoras. A análise de conteúdo foi empregada para tratar os resultados da tensão relacional e dos elementos da agência humana: iterativo, projetivo, prático-avaliativo. Os resultados mostram que gestores prático-avaliativos realizam mudanças buscando melhoria de resultados e estão atentos aos desafios, enquanto gestores iterativos continuam trabalhando como sempre trabalharam, atendendo os poucos e fidelizados clientes, sendo indiferentes às adversidades. A despeito de práticas estratégicas distintas, na dimensão projetiva, os gestores compartilham uma imagem: a morte das videolocadoras. Assim, a estratégia enquanto prática social abarca temáticas da mudança e do declínio organizacionais enquanto vivência (antecipada) do luto nas organizações.

Authors: Capitani Daniel Henrique Dario , Cruz Junior José César , Tonin Julyerme Matheus
Published: May 2018

Este trabalho visa avaliar o grau de integração nos mercados de etanol dos EUA e Brasil, investigando a existência de um preço como referência internacional que possa servir de base aos agentes dessa cadeia produtiva. Foi estimado um modelo autorregressivo vetorial estrutural com correção de erros (SVEC), considerando tanto os preços de etanol, milho e açúcar, no Brasil e nos Estados Unidos, quanto o preço internacional do petróleo. Posteriormente, foram examinadas eficiências de estratégias simultâneas de hedge considerando operações com os contratos futuros de etanol na CME, NYMEX e BM&FBOVESPA. Em geral, os resultados indicam que tais mercados possuem baixo grau de integração, respondendo majoritariamente a variáveis domésticas. Além disso, evidencia-se uma baixa eficiência na operação de hedge cruzado com contratos futuros de etanol em outras bolsas, sugerindo, portanto, uma baixa integração dos preços no mercado internacional.

Published: May 2018

The world is undergoing nothing less than a major revolution in the way people spend their time and thought on the future of their endeavors. Perhaps, the most important mental and spiritual principle ever discovered is that you become what you think about most time and the actions and inactions you put in place in managing the resources available to you. In view of the fact that resources abound everywhere, they may have little or no value unless you pull out the essentials peculiar to your needs and apply it appropriately. The management of these resources can make you happy or sad, distracted or depressed, popular or unpopular, confident or insecure, positive or negative, successful or unsuccessful, powerful or powerless, victim or victor, a hero or a coward. The management style adopted by an executive determines the level employees feel and the seeds of success that will be planted. As the world moves from the era of things to the mental age, it will be only those that maximally apply the most impressing management principles that will scale the navigational flexibilities of our time. It is on the strength of this that this study is designed conceptually to unveil issues of contemporary management of secondary schools in Benue state of Nigeria. The paper is therefore structured   in the following sub-headings: introduction, types of management styles, types of motivational programmes in the workplace, team building, and tips for team building, challenges of teamwork and a conclusion is drawn.
Design and Development of Plastic Filament Extruder for 3D Printing
Authors: Wankhade Mamta H. , Bahaley Satish G.
Published: May 2018

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. As 3D printing is growing fast and giving a boost to product development, the factories doing 3D printing need to continuously meet the printing requirements and maintain an adequate amount of inventory of the filament. As the manufactures have to buy these filaments from various vendors, the cost of 3D printing increases. To overcome the problem faced by the manufacturers, small workshop owners, the need of 3D filament making machine arises. This project focuses on designing and fabricating a portable fused deposition 3D printer filament making machine with cheap and easily available components to draw 1.75 mm diameter ABS filament.

Authors: Passias Peter G. , Poorman Gregory , Lurie Jon , Zhao Wenyan , Morgan Tamara , Horn Samantha , Bess Robert Shay , Lafage Virginie , Gerling Michael , Errico Thomas J.
Published: May 2018

Background:

Factors that are relevant to the decision regarding the use of surgical treatment for degenerative spondylolisthesis include disease-state severity and patient quality-of-life expectations. Some factors may not be easily appraised by the surgeon. In prospective trials involving patients undergoing nonoperative and operative treatment, there are instances of crossover in which patients from the nonoperative group undergo surgery. Identifying and understanding patient characteristics that may influence crossover from nonoperative to operative treatment will aid understanding of what motivates patients toward pursuing surgery.

Methods:

Patients with degenerative spondylolisthesis who were randomized to nonoperative care in a prospective, multicenter study were evaluated over 8 years of enrollment. Two cohorts were defined: (1) the surgery cohort (patients who underwent surgery at any point) and (2) the nonoperative cohort (patients who did not undergo surgery). A Cox proportional hazards model, modeling time to surgery, was used to explore demographic data, clinical diagnoses, and patient expectations and attitudes after adjusting for other variables. A subanalysis was performed on surgery within 6 months after enrollment and surgery >6 months after enrollment.

Results:

One hundred and forty-five patients who had been randomized to nonoperative treatment, 80 of whom crossed over to surgery, were included. In analyzing baseline differences between the 2 cohorts, patients who underwent surgery were younger; however, there were no significant difference between the cohorts in terms of race, sex, or comorbidities. Treatment preference, greater Oswestry Disability Index score, marital status, and no joint problems were predictors of crossover to surgery. Clinical factors, including stenosis, neurological deficits, and listhesis levels, did not show a significant relationship with crossover. At the time of long-term follow-up, the surgery cohort showed significantly greater long-term improvement in health-related quality of life (p < 0.001). The difference was maintained throughout follow-up.

Conclusions:

Neurological symptoms and diagnoses, including listhesis and stenosis severity, did not predict crossover from nonoperative care to surgery. Attitudes toward surgery, greater Oswestry Disability Index score, marital status, and no joint problems were independent predictors of crossover from nonoperative to operative care. Certain demographic characteristics were associated with higher rates of crossover, although they were connected to patient attitudes toward surgery.

Reduction of Blood Loss by Tranexamic Acid Following Total Hip and Knee Arthroplasty
Authors: Gianakos Arianna L. , Hurley Eoghan T. , Haring R. Sterling , Yoon Richard S. , Liporace Frank A.
Published: May 2018

Background:

This study involved a meta-analysis of 36 published studies to examine the efficacy of intravenous (IV) and intra-articular (IA) tranexamic acid (TXA) in reducing blood loss, drain output, thromboembolic complications, and hospital stay following total hip and total knee arthroplasty. This study also evaluated whether treatment with a combination of both IA and IV TXA has an effect on these outcomes. Lastly, this study attempted to analyze the method and technique of TXA administration in order to establish a best practice for its use in reducing overall blood loss in arthroplasty procedures.

Methods:

MEDLINE, Embase, and the Cochrane Library database were screened. Studies comparing IV TXA with IA TXA or with combined IV and IA TXA were included. Data including total blood loss, drain output, thromboembolic complications, and hospital stay, where available, were analyzed using meta-analysis with fixed effects. Results are presented as the standardized mean difference (SMD), and meta-regression was employed to explore plausible demographic contributions to heterogeneity.

Results:

Twenty-eight randomized controlled trials, 3 prospective cohort studies, and 5 retrospective cohort studies with 5,499 patients were included in this review. IA administration during total knee arthroplasty showed a significant advantage in terms of total blood loss (SMD = −0.14, 95% confidence interval [CI] = −0.027 to −0.02, I2 = 78.2%) and drain output (SMD = −0.30, 95% CI = −0.43 to −0.18). There was no significant difference between IV and IA administration in total hip arthroplasty. Combined IA plus IV TXA was associated with a significant reduction in blood loss versus IV TXA alone in both total knee arthroplasty and total hip arthroplasty. IV TXA dosing varied, as 14 (39%) of the studies used a weight-based approach while 22 (61%) used a standard dose. Twenty-seven (96%) of 28 studies of IA administration used standard dosing while 1 study followed a weight-based protocol. There was no difference in symptomatic thromboembolic complications, with overall rates in total knee arthroplasty and total hip arthroplasty of 1.0% and 1.0% for IV administration and 1.1% and 0.3% for IA administration, respectively. There was no difference in length of hospital stay for IV versus IA TXA administration.

Conclusions:

IA TXA, either alone or in conjunction with IV TXA, reduces total blood loss and/or drain output in total knee arthroplasty and total hip arthroplasty. Optimal methodology remains to be clarified; however, there are substantial economic benefits of utilizing either IV or IA TXA, with greater cost benefits when using IA TXA.

Authors: Iyer Sravisht , Sheha Evan , Fu Michael C. , Varghese Jeffrey , Cunningham Matthew E. , Albert Todd J. , Schwab Frank J. , Lafage Virginie C. , Kim Han Jo
Published: May 2018

* Changes in spinal alignment trigger several compensatory changes in the pelvis and lower extremities to maintain upright posture. Activating these mechanisms of compensation may require increased energy expenditure to maintain upright posture.

* The Scoliosis Research Society-Schwab Adult Spinal Deformity (ASD) classification system allows for a uniform classification and discussion of ASD. A higher sagittal deformity classifier is associated with increased disability.

* Age-related changes in spinal alignment are important to consider when setting alignment goals for deformity correction. Less-aggressive correction should be considered in older patients because of their increased risk for complications.

* A structured approach to the treatment of ASD consists of 6 steps: (1) find and quantify the driver of deformity, (2) evaluate how deformity impacts global alignment, (3) define alignment targets, (4) determine spinal flexibility, (5) choose a surgical strategy, and (6) execute this strategy intraoperatively in a controlled fashion.

Return and Volatility Spillovers Effects: Study of Asian Emerging Stock Markets
Authors: Roni Bhowmik , Abbas Ghulam , Wang Shouyang
Published: May 2018

This paper examines the extent of contagion and interdependence across the six Asian emerging countries stock markets (e.g., Bangladesh, China, India, Malaysia, the Philippine, and South Korea) and then try to quantify the extent of the Asian emerging market fluctuations which are described by intra-regional contagion effect. These markets experienced both fast growth and key upheaval during the sample period, and thus, provide potentially rich information on the nature of border market interactions. Using the daily stock market index data from January 2002 to December 2016 (breaking the 15 years data set into three sub periods; pre-crisis, crisis, and post crisis periods); particularly make attention to the global financial crisis of 2007∼2008. The return and volatility spillovers are modeled through the GARCH (generalized autoregressive conditional heteroscedasticity), pairwise Granger causality tests, and the forecast error variance decomposition in a generalized VAR (vector auto regression) models. This paper shows that volatility and return spillovers behave very differently over time, during the pre-crisis, crisis, and post crisis periods. Importantly, Asian emerging stock markets interaction is less before the global financial crisis period. The return and volatility spillover indices touch their respective historical peaks during the global financial crisis 2007∼2008, however Bangladeshi market faces this condition in 2009∼2010.
Predicting Trend of High Frequency CSI 300 Index Using Adaptive Input Selection and Machine Learning Techniques
Authors: Kong Ao , Zhu Hongliang
Published: May 2018

High-frequency stock trend prediction using machine learners has raised substantial interest in literature. Nevertheless, there is no gold standard to select the inputs for the learners. This paper investigates the approach of adaptive input selection (AIS) for the trend prediction of high-frequency stock index price and compares it with the commonly used deterministic input setting (DIS) approach. The DIS approach is implemented through computation of technical indicator values on deterministic period parameters. The AIS approach selects the most suitable indicators and their parameters for the time-varying dataset using feature selection methods. Two state-of-the-art machine learners, support vector machine (SVM) and artificial neural network (ANN), are adopted as learning models. Accuracy and F-measure of SVM and ANN models with both the approaches are computed based on the high-frequency data of CSI 300 index. The results suggest that the AIS approach using t-statistics, information gain and ROC methods can achieve better prediction performance than the DIS approach. Also, the investment performance evaluation shows that the AIS approach with the same three feature selection methods provides significantly higher returns than the DIS approach.
Design of an Optimal Preview Controller for Dual-Rate Linear Discrete-Time Systems
Authors: Guo Yujian , Liao Fucheng
Published: May 2018

A dual-rate preview control strategy for a type of discrete-time system is proposed based on the theory of multirate control. First, by using the discrete lifting technique, the general dual-rate discrete-time system is converted into a single-rate augmented system. On this basis, the augmented error system is constructed by introducing a first-order difference operator and the previewable reference signal. Then the tracking problem is transformed into a regulator problem of the augmented error system. The optimal preview control law of the augmented error system is obtained by using standard linear quadratic optimal preview control theory, and then the optimal preview controller of the original system is derived. In addition, the necessary and sufficient conditions for the controller are given. Finally, simulation results show the effectiveness of the proposed method.
Effect of Phytohormones of Kinetin and Epibrassinolide on Content and Intracellular Localization of Glucosides and Free Amino Acids in Pea Plants Cells (Pisum sativum L.)

During
injection of kinetin and epibrassinolide in pea seedlings (Pisum sativum L.) an increase of content of specific for this
compound isosuccinimide-β-glucoside (IS-glucoside) for 15-30%,
ethyl-β-glucoside for 40-80%, GABA free amino acids, glutamate and alanine only
under kinetin for 15-20% was observed. The field experiments showed an increase
of aglycone content but the amount of IS-glucoside decreased at first and then
increased 14 days after plant treatment with phytohormones. It was shown that
effect of phytohormones on content of IS-glucosides and free amino acids was
dependent on action time and age of plant. By using membrane trophic compound
of DMSO it was discovered that in pea seedlings cells the vacuolar fund of
IS-glucoside was 70% of initial and aglycone with γ-aminobutyric acid as its
precursor were localized in cytoplasm. Aspartate and glutamate were almost
equally distributed between cytoplasmic and vacuolar cell funds. It is
suggested that reactions of pyrrolidone structure of IS-glucoside aglycone
formation and synthesis of the glucoside were processed in cytoplasm. Further
IS-glucoside was transferred and stored in vacuoles of pea seedlings cells by
contrast with ethyl-β-glucoside mainly localized in cytoplasm.

Water quality objectives for body contact recreation (REC-1) in Newport Bay, CA are not being attained. To evaluate the health implications of this non-attainment, a comprehensive health-based investigation was designed and implemented. Bacterial indicator data indicate that exceedances of the water quality objectives are temporally sporadic, geographically limited and most commonly occur during the time of the year and/or in areas of the bay where the REC-1 use is low or non-existent. A disease transmission model produced simulated risk estimates for recreation in the Bay that were below levels considered tolerable by the US EPA (median estimate 0.9 illnesses per 1,000 recreation events). Control measures to reduce pathogen loading to Newport Bay are predicted to reduce risk by an additional 16% to 50%. The results of this study indicate that interpreting the public health implications of fecal indicator data in recreational water may require a more rigorous approach than is currently used.

Introduction: Schistosoma mansoni is responsible for virtually all reported cases of schistosomiasis
in Latin America and the emergence of praziquantel- and oxaminiquine-resistant strains
makes it urgent to develop new schistosomicide agents. Dihydrofolate reductases (DHFR) from bacteria
and protozoan parasites are considered validated macromolecular targets for this goal, but S. mansoni
DHFR (SmDHFR) has been largely overlooked. To fill this gap in knowledge, the present work describes
optimized conditions to carry out thermal shift assays with SmDHFR, as well as a balanced kinetic
assay that supports 2,4-diaminopyrimidine derivatives as SmDHFR inhibitors. The most potent
inhibitor (2a) shows a large shift of the melting temperature (ΔTm = + 8 ± 0,21 ºC) and a low micromolar
IC50 value (12 ± 2,3 μM). Both thermal shift and classical kinectic assay suggest that 2a binds to the
substrate binding site (competitive inhibition mechanism). This information guided docking and molecular
dynamics studies that probed 2a interaction profile towards SmDHFR.

Conclusion:

In conclusion, this work not only provides standardized assay conditions to identify
SmDHFR inhibitors, but also describes the binding profile of the first low micromolar inhibitor of this
macromolecular target.

BACKGROUND

To support adolescents through transition from pediatrics to adult care, health care providers and families help teens gain knowledge and develop self-management skills. Peer mentoring can provide meaningful support and has been associated with improved health outcomes in patients with other chronic conditions. Peer mentoring is an appealing way to provide support, but it is imperative to consider the unique needs of adolescents to ensure its success.

OBJECTIVE

The objective of our study was to identify the peer mentoring wants and needs of youth with hemophilia in order to guide the development of a new program.

METHODS

In this qualitative study, we interviewed a convenience sample of youth with hemophilia from 2 Canadian hemophilia treatment centers. Two iterative cycles of audiorecorded, semistructured individual interviews were conducted. Descriptive statistics and content analyses were used to organize data into categories that reflected emerging themes.

RESULTS

In total, we recruited 23 participants aged 12-20 years, with a mean age of 14.91 (2.57) years. When asked about program design, participants weighed the importance of flexibility in delivery (eg, Web-based, in person, text messaging [short message service]), content (eg, structured vs unstructured), frequency of sessions, and length of the program. Participants identified some potential challenges such as scheduling issues, comfort level for disease discussion, and discordant mentor-mentee personality types. The program was viewed as a positive medium for connecting peers with hemophilia.

CONCLUSIONS

Adolescents with hemophilia expressed interest in a peer mentoring program and provided valuable insight that will be applied in the development of a peer mentoring program for youth with hemophilia.
