Published: September 2017

El objetivo del estudio fue caracterizar a los productores de piloncillo con la finalidad de contribuir con información que permita conocer la importancia del uso de tecnología en la elaboración de piloncillo granulado en la comunidad de Aldzulup Poytzén, Tancanhuitz, San Luis Potosí. Mediante muestreo no probabilístico, fueron entrevistados 36 productores de piloncillo. El estudio de las variables escalares se realizó mediante análisis de varianza para comparación de medias y análisis de correlación. Se encontraron diferencias significativas (p<0.05) entre el nivel tecnológico de los productores de piloncillo (alto, medio y bajo). No obstante, no hubo diferencias en los niveles de producción obtenidos entre ellos. Existe una restrictiva vinculación al mercado motivada por factores de comercialización, que les dirige hacia la venta de piloncillo industrial; 97.22% de los productores venden este tipo de piloncillo. La agricultura familiar de los productores de piloncillo tiene una diversificación productiva en sus actividades relacionadas con la agricultura y ganadería (siembra de maíz, frijol, especies frutales, gallinas, porcinos). Se concluye que, la elaboración de piloncillo granulado, no se explica solo por el bajo nivel tecnológico, ya que este tipo de piloncillo es producido por los tres estratos. Además, el estudio corrobora la diversificación de actividades productivas de la agricultura familiar como una estrategia de sostenimiento de este tipo de productores.

Published: September 2017

La Región Lagunera destaca como la zona melonera más importante de México con una superficie anual de alrededor de 5,000 hectáreas y una producción de 134,000 toneladas. La producción de esta región se ve amenazada por las importaciones, plagas, enfermedades, problemas de comercialización, altos costos de producción, falta de financiamiento y mayores exigencias de calidad por parte de las cadenas comerciales de tiendas de autoservicio. El objetivo de este trabajo fue proponer una serie de estrategias, alianzas y portafolio de negocios para mejorar la competitividad de la cadena productiva de melón en la Comarca Lagunera para evitar que sea desplazada por regiones competidoras del país y del extranjero.Método: En este trabajo se utilizó la metodología conocida como "Focus Group" o grupos de enfoque. Se contó con 27 participantes de los cuales 18 fueron productores de melón de la Comarca Lagunera, cinco técnicos, dos funcionarios de la Secretaría del Desarrollo Rural del gobierno del estado de Coahuila y dos representantes de empresas proveedoras de agro insumos. Se trabajó durante dos días en varias dinámicas basadas en formatos previamente elaborados por los responsables del proyecto. La información obtenida se clasificó habiéndose obtenido como resultado las fuerzas competitivas, las estrategias, las alianzas y el portafolio de negocios.Resultados: Se identificaron seis estrategias para el desarrollo de la competitividad, su alcance, limitaciones y el tiempo que se estima para que se lleven a cabo. Las estrategias fueron: 1) capacitación técnica tendiente a obtener la certificación en inocuidad, 2) transferencia del paquete tecnológico, 3) gestión de recursos para financiar y asegurar la producción, 4) venta directa de melón a las cadenas comerciales de tiendas de autoservicio bajo el esquema de contrato, 5) establecer alianzas con instituciones académicas y de investigación y 6) establecimiento de alianzas con dependencias estatales y federales del Sector Agropecuario. En cuanto a las alianzas estas son específicas para cada estrategia destacando aquellas con dependencias federales y estatales; universidades y centros de investigación del sector agropecuario; instituciones de financiamiento y aseguramiento al campo y cadenas de tiendas de autoservicio. Finalmente, en el portafolio de negocios se propuso la creación de 1) una Gerencia comercializadora de melón, 2) una unión de crédito, 3) una agencia técnica de prestación de servicios profesionales y 4) una agencia comercializadora de equipos e insumos.Conclusión: Los resultados permitieron definir las principales estrategias, alianzas a realizar y el portafolio de negocios tendientes a desarrollar la productividad y competitividad del melón en la Comarca Lagunera. Su implementación dependerá de que los productores puedan organizarse y realizar las acciones aquí propuestas.

Published: September 2017

Background:
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by extracellular
amyloid plaque and neurofibrillary tangles in the brain. Studies have shown that neurons are
able to re-enter the cell cycle, but not enough to enable full replication. This leads to cell death and consequent
neurodegeneration.

Objective:
This study aimed to characterize the expression of the MAPT gene and CDK5 (the gene involved
in cell cycle regulation) in brain samples from patients with AD and controls.

Method:
The real-time-PCR technique was used to characterize 150 samples from three areas of the
brain (entorhinal cortex, auditory cortex, and hippocampus) of 26 AD patients and 24 healthy elderly
subjects.

Results:
When the brain samples were analyzed collectively, a decrease in CDK5 and MAPT gene expression
was found in AD patients. When each groups' samples were separated by area of the brain and
compared, significant differences were found in CDK5 expression in the hippocampus and the entorhinal
cortex. In both cases, mRNA was lower in the AD group (p=0.0001); however, the same analysis
using the MAPT gene revealed no significant statistical differences. No statistical differences were found
when gene expression was compared between the different regions of the brain within each group.

Conclusion:
These results may contribute to a better understanding of the involvement of CDK5 and
MAPT genes in AD in that they consider different areas of the brain that are affected differently based
on disease progression. The main challenge is to establish an effective therapy for this debilitating disease
in the future.
Representation of Bali in Tourism Advertisement Videos

Published: September 2017

Employing the Halliday’s theory of transitivity (1985), this study explores the representation of Balinese religion, culture, and nature in the Bali tourism advertisements videos produced by Bali’s Tourism Office, Bali Tourism Board and Ministry of Tourism of Indonesian Republic. The study reveals that the language of the advertisements mostly describes Bali in terms of material process, mental and relational process. In terms of relational process, the beauty of Bali’s culture and nature is capitalized and portrayed as having certain kind of qualities: indicated by the use of adjectives typical to tourism advertisement such as mesmerizing, exotic, unique, etc. and it is constantly defined as paradise. A stark difference, however, occurs in terms of the participants of the clause. In the advertisement produced by the Bali Tourism office, the participants having the role of ‘actors’, ‘senser’ and ‘carrier’, are Balinese people, Bali’s nature, and culture. The advertiser, taking the position of ‘we’, the Balinese, speaks to the world, explaining their home island, culture and belief. On the other hand, the more ‘mainstream’ advertisements of Bali, give more to the prospective tourists, addressed as ‘you’. Here the tourists are the actors and sensers of everything Bali can offer. Bali is depicted as purely a travel destination that can satisfy the visitors and in the position of passive ‘phenomenon’ and ‘goals’. The advertisers are taking the position of ‘the travel agent’, the third party that promotes Bali

Published: September 2017

Background
In 2010, the human papillomavirus (HPV) vaccination was introduced in the Dutch National Immunization Program for 12-year-old girls, aiming to reduce the incidence of cervical cancer in women. HPV vaccination uptake turned out to be lower than expected: 61% versus 70%, respectively. Mothers were shown to play the most important role in the immunization decision about this vaccination. They had also expressed their need for interactive personal information about the HPV vaccination over and above the existing universal general information. To improve the effectiveness of the existing education about the HPV vaccination, we systematically developed a Web-based tailored intervention with virtual assistants providing mothers of girls to be invited with tailored feedback on their decision making about the HPV vaccination.

Objective
The aim of this study was to evaluate the effectiveness of the Web-based tailored intervention for promoting HPV vaccination acceptance by means of a randomized controlled trial (RCT).

Methods
Mothers were recruited via the Dutch vaccination register (Praeventis) (n=36,000) and three Web-based panels (n=2483). Those who gave informed consent (N=8062) were randomly assigned to the control (n=4067) or intervention condition (n=3995). HPV vaccination uptake, as registered by Praeventis once the HPV vaccination round was completed, was used as the primary outcome. Secondary outcomes were differential scores across conditions between baseline (before the provided access to the new tailored intervention) and follow-up (just before the first vaccination) regarding the mothers’ degree of informed decision making (IDM), decisional conflict, and critical determinants of HPV vaccination uptake among which are intention, attitude, risk perception, and outcome beliefs.

Results
Intention-to-treat analysis (N=8062) showed a significant positive effect of the intervention on IDM, decisional conflict, and nearly all determinants of HPV vaccination uptake (P<.001). No effect was found on uptake (P=.60). This may be attributed to the overall high uptake rates in both conditions. Mothers evaluated the intervention as highly positive, including the website as well as the virtual assistants that were used to deliver the tailored feedback.

Conclusions
This computer-tailored intervention has the potential to improve HPV vaccination acceptability and IDM and to decrease decisional conflict among mothers of invited girls. Implications for future research are discussed.

Ejournals in Education: Just Generating Excitement or Living up to the Promise?
Authors: Ganesh Tirupalavanam G. 
Published: September 2017

The Internet makes scholarly electronic journals an opportune global mode of communication for scholarly exchange, where national and international borders are erased. The American Educational Research Association Special Interest Group, Communications among Researchers (AERA SIG CR) lists over one hundred electronic journals i n the field of education that are scholarly, peer-reviewed, full text and accessible without cost on the world wide web (see http://aera-cr.ed.asu.edu/links.html). Are these ejournals merely poor electronic imitations of print journals? Granted, the use of the Internet to publish peer-reviewed scholarship has the potential of democratizing access. But are such scholarly exchanges making effective use of the electronic medium? What innovative things can be done with new technology? How can electronic journals be preserved, used, and managed over time?
The Influence of Extrinsic Motivation on Innovative Work Behaviour with Moderating Role of Quality Culture

Published: September 2017

Objective: This study explored the influence of extrinsic motivation on innovative work behaviour in higher education institutions in Iraq as moderated by quality culture. Although the employees' innovative work behaviour is the key sources of organizational innovation, it does not develop automatically. Leadership should give employees suitable work incentives and more motivation to increase their innovative behaviour.
Methodology:This study discusses the theoretical concepts based on Social Exchange Theory and previous studies to explore the logical relationships between research variables.
The results: The research study concludes that the feeling of extrinsic motivation is enormously important to realize the continuous flow of innovative work behavior, especially through the influence of quality culture on this relationship. Likewise, in line with the Social Exchange Theory, extrinsic motivation may positively influence innovative work behaviour. In addition, the quality culture, as one of the contextual factors, is very important for the higher education institutions as it affects the innovative work behaviour of employees.
Implication: The results are expected to have both theoretical and practical contributions to enable Iraqi higher education institutions to improve the level of innovation. The results of this study can be used as a strategy by the administration for the purpose of improving innovative work behaviour. This study involves several limitations, including the lack of empirical examination. The future empirical studies may use this theoretical framework to cover this aspect.

Published: September 2017

AbstractThin film battery electrodes of the olivine structure LiFePO4and the spinel phase LiMn2O4are deposited through ion-beam sputtering. The intercalation kinetics is studied by cyclo-voltammetry using variation of the cycling rate over 4 to 5 orders of magnitude. The well-defined layer geometry allows a detailed quantitative analysis. It is shown that LiFePO4clearly undergoes phase separation during intercalation, although the material is nano-confined and very high charging rates are applied. We present a modified Randles–Sevcik evaluation adapted to phase-separating systems. Both the charging current and the overpotential depend on the film thickness in a systematic way. The analysis yields evidence that the grain boundaries are important short circuit paths for fast transport. They increase the electrochemical active area with increasing layer thickness. Evidence is obtained that the grain boundaries in LiFePO4have the character of an ion-conductor of vanishing electronic conductivity.
Enthalpies of formation of layered LiNixMnxCo1–2xO2 (0 ≤ x ≤ 0.5) compounds as lithium ion battery cathode materials

Published: September 2017

AbstractLayer-structured mixed transition metal oxides with the formula LiNixMnxCo1–2xO2 (0 ≤ x ≤ 0.5) are considered as important cathode materials for lithium-ion batteries. In an effort to evaluate the relative thermodynamic stabilities of individual compositions in this series, the enthalpies of formation of selected stoichiometries are determined by high temperature oxide melt drop solution calorimetry and verified by ab-initio calculations. The measured and calculated data are in good agreement with each other, and the results show that LiCoO2–LiNi0.5Mn0.5O2 solid solution approaches ideal behavior. By increasing x, i. e. by equimolar substitution of Mn4+ and Ni2+ for Co3+, the enthalpy of formation of LiNixMnxCo1–2xO2 from the elements becomes more exothermic, implying increased energetic stability. This conclusion is in agreement with the literature results showing improved structural stability and cycling performance of Ni/Mn-rich LiNixMnxCo1–2xO2 compounds cycled to higher cut-off voltages.
Modification of microstructure and mechanical properties of Al–Zn–Mg/3 wt.% Al2O3 composite through semi-solid thermomechanical processing using variable loads
Authors: Hajizamani Mohsen , Alizadeh Mostafa 
Published: September 2017

Abstract
The microstructure and mechanical properties of Al–Zn–Mg/3 wt.% Al2O3 composite were modified through a thermomechanical processing technique. The powders were cold pressed and solid state sintered for 90 min under argon atmosphere. Thermomechanical processing was then applied to the solid state sintered samples, which consisted of cold pressing followed by partial remelting for 30 min under argon atmosphere. Four different loads in the thermomechanical processing were used to investigate the effects of compressive loads on the microstructures and the mechanical properties. The results revealed modifications in the microstructure of the thermomechanically processed samples with the optimum combination of properties in the sample modified by applying the load of 250 MPa. Increasing the thermomechanical processing load decreased the amounts of porosity by about 7 %, decreased the average grain size to about 4 μm, enhanced the compressive yield strength to about 295 MPa, and increased the microhardness values from 250 HV to 600 HV. In addition, the energy absorption capacity increased by about three times.
Investigations on Additive Manufacturing of WCCo Hard Metals by Laser Beam Melting

Published: September 2017

Abstract
Tungsten carbide-cobalt hard metal produced by additive manufacturing offers opportunities to meet the increasingly complex requirements of high-performance machining. Besides a high level of design freedom and the easy integration of functional properties, the additive manufacturing of hard metals also offers potential for cost savings and conservation of resources. A window of favorable process parameters for laser beam melting was established using commercially available carbide powder with 17 % Co content, which serves to build carbide samples by laser-based additive manufacturing. Compared to conventionally manufactured carbides, deviations can still be noticed with regard to microstructural and mechanical properties. However, bending strengths of > 1 000 MPa and fracture toughness in the range of 10–12 Mpa √m are promising for the future additive manufacturing of WCCo hard metals.
Developments in scientific communication: Considerations on the value chain
Authors: Roosendaal Hans E. , Geurts Peter A.Th.M. , van der Vet Paul E. 
Published: September 2017

This article analyses the transformation of the value chain of scientific information in response to concomitant changes in scientific research and education. The scientific communication market is described in terms of main driving forces and their interplay. These forces are the actor (author/reader), accessibility, content, and applicability pairs. Scientific communication is described in this article in terms of its four functions: registration, archive, awareness, and certification. The introduction of these forces and functions allows a structural analysis of the scientific communication market and allows us to discuss aspects of structural continuity in, e.g., describing the transformation from a paper-based system to communication in a digital environment. The developments are seen to emphasise the already existing autonomous development towards a “unified archive”, lead us to review certification policies to include elements external to research and lead us to consider new structures for scientific communication, and publications. The new structures can be seen to result from the interactions in the market as modelled by the forces and the functions. The distinction between formal and informal communication is seen to become less useful. The need to review the structure and organisation of the market becomes evident, in particular if we consider communication during research and education as well. This leads us to speculate whether elements of the virtual organisation are of relevance.

Published: September 2017

A new and efficient immobilized form of phenylalanine ammonia-lyase (PAL) was obtained by covalent linkage onto amino functionalized single-walled carbon nanotubes (SwCNTNH2) as carrier. The catalytic properties of the resulted nanostructured biocatalyst (SwCNTNH2-PAL) were tested in the kinetic resolution of racemic 2-amino-3-(thiophen-2-yl)propanoic acid 1 by ammonia elimination and in the enantiotope selective addition of ammonia onto (E)-3-(thiophen-2-yl)acrylic acid 2. SwCNTNH2-PAL was a durable biocatalyst in batch mode for ammonia elimination from 1 (>85% of original activity after 7 cycles) and in ammonia addition to 2 (>70% of original activity after 3 cycles in 6 M NH3 , pH 10.0). The ammonia addition onto 2 was also studied in a continuous-flow microreactor packed with SwCNTNH2-PAL (2 M NH3, pH 10.0, 15 bar) in the 30-80 °C temperature range. No significant loss of PAL activity was observed over 72 h in the microreactor up to 60 °C. Productivity of SwCNTNH2-PAL at 30 °C was significantly higher in the enantiotope selective ammonia addition performed in a packed-bed reactor operated in continuous-flow mode (rflow =2.41 mmol min-1 g-1) than in the reaction performed in batch system (rbatch = 1.38 mmol min-1 g-1).
