COMBINED NUMERICAL, FINITE ELEMENT AND EXPERIMENTAL-OPTIMIZATION APPROACH IN THE PRODUCTION PROCESS OF MEDIUM-VOLTAGE, RUBBER-INSULATED ELECTRIC CABLES VULCANIZED WITH STEAM WATER. PART 1: DSC AND RHEOMETER EXPERIMENTAL RESULTS
Authors: Milani G. , Galanti A. , Cardelli C. , Milani F. , Cardelli A.
Published: June 2015

The standard industrial process to produce medium-voltage electric cables based on EPDM consists of cross-linking by peroxides with high-temperature steam (pressurized water vapor). Suboptimal material cross-linking is usually due to a decrease of the temperature along the vulcanization pipe. Temperature variations are connected to variations in steam pressure into pipe system. A combined numerical and experimental approach to optimize the production process of medium-voltage, rubber-insulated electric cables vulcanized with steam water is presented. The numerical part of this process is based on the use of finite elements and an optimization genetic algorithm (GA) and will be presented in Part 2. In Part 1, attention focuses on the experimental investigation. In particular, the final cross-linking degree is experimentally obtained by means of differential scanning calorimetry (DSC) determination of nondecomposed peroxide from the external layer to the core of the cable insulation. The final task is to minimize the difference between numerically predicted and experimentally determined cross-linking degree using a steam-temperature profile along the pipe to explain the variations. A preliminary evaluation of kinetic-reaction constants of rubber cured with peroxides is provided with the support of a comprehensive experimental investigation of the curing process by means of standard rheometer characterizations done at different curing temperatures. An existing mathematical, kinetic model is applied to the experimentally determined rheometer curves, allowing the determination of partial-reaction kinetic constants used in the finite-element computations.
The Manifestation of Internal Corporate Social Responsibility on Employee’s Behaviour in Small Medium Sized Enterprises
Authors: Low Mei Peng , Ong Seng Fook
Published: June 2015

Corporate Social Responsibility (CSR) has gained increasing attention and popularity since the last decade. There are many CSR debates arise since then. These debates were shaped by trends and fundamental changes of the political, social, and economic spheres of life. Tracing back, the precursor to CSR was topic of charitable giving, which had been in existence since 1980s. Todate, CSR has evolved to a business concept that had been accepted widely. Business corporations are focusing on CSR due to tremendous pressures from the society. Presently, CSR approach has emerged from focusing on the shareholders to stakeholders due to the acknowledgement of the crucial roles of stakeholders in every organisation. Stakeholder management and CSR is a relational affair. Stakeholder theory involves list of critical stakeholders namely employees, suppliers, customers, media, local communities, NGOs, that could be source of new competitive advantage. This present a research agenda to look into internal CSR practices as to how it manifest among the crucial stakeholders of every organisation, i.e. the employees, on their attitudes and behaviours. As Small Medium Sized Enterprises (SMEs) are gaining its foothold in Malaysia, they also encountered many challenges, one of these is the issue of high employee turnover that lead to substantial costs to the organisations. The findings reveal that internal CSR practices enhanced employee’s job satisfaction and also resulted in the reduction of employee’s turnover intention. It was interesting to discover that internal CSR practices enhance employee’s organisational commitment like job satisfaction, but it failed to reduce employee’s turnover intention through enhanced organisation commitment as a result of internal CSR practices. The results also show that perceived ease of movement has an impact on employee’s turnover intention.
The “Black Man's Bible”
Authors: Sellers Allison Paige
Published: June 2015

The Afro-Athlican Constructive Gaathly was an Afrocentric religious movement begun by Anguillan preacher Robert Athlyi Rogers during the interwar period. Its sacred text, the Holy Piby, represented a new truth reserved for people of African descent that promised to liberate them from oppression. More importantly for the purpose of this work, the Holy Piby charged followers with reclaiming Africa, overthrowing white rule, and taking their place as the greatest nation on earth. Despite its brevity, Rogers's movement was indicative of a significant historical moment in the Alantic world, one in which multiple new Black religions emerged to challenge white supremacy and negotiate the status of people of color. In the global conversations about race and progress, nationalism and identity, economics and politics, and religion and self-determination, Rogers was able to articulate what amounted to a Black supremacist ideology embedded within a religious framework.
Soil Health and Related Ecosystem Services in Organic Agriculture
Authors: Abbott Lynette K. , Manning David A. C.
Published: June 2015

Soil health is dependent upon complex bio-physical and bio-chemical processes which interact in space and time. Microrganisms and fauna in soil comprise highly diverse and dynamic communities that contribute, over either short or long time frames, to the transformation of geological minerals and release of essential nutrients for plant growth. Certified organic soil management practices generally restrict the use of chemically-processed highly soluble plant nutrients, leading to dependence on nutrient sources that require microbial transformation of poorly soluble geological minerals. Consequently, slow release of nutrients controls their rate of uptake by plants and associated plant physiological processes. Microbial and faunal interactions influence soil structure at various scales, within and between crystalline mineral grains, creating complex soil pore networks that further influence soil function, including the nutrient release and uptake by roots. The incorporation of organic matter into soil, as either manure or compost in organic farming systems is controlled to avoid excessive release of soluble nutrients such as nitrogen and phosphorus, while simultaneously contributing an essential source of carbon for growth and activity of soil organisms. The interdependence of many soil physical and chemical processes contributing to soil health is strongly linked to activities of the organisms living in soil as well as to root structure and function. Capitalizing on these contributions to soil health cannot be achieved without holistic, multiscale approaches to nutrient management, an understanding of interactions between carbon pools, mineral complexes and soil mineralogy, and detailed examination of farm nutrient budgets.

Badania nad wpływem wirowania na ukorzenianie się zdrwniałych sadzonek czarnych porzeczek [Effect of centrifugation on the rooting of the blackcurrant cuttings]
Authors: Lipecki Janusz , Selwa Jan
Published: June 2015

Hardwood cuttings of the blackcurrant, cv. Blacksmith, were centrifuged at five different periods at 1500, 2750 and 5000 rpm, for 10, 20 and 40 min and diffusates were collected. The rooting response was examined after three weeks. The activity of the growth substances in the diffusates was studied using bioassays. Stimulation of the rooting of cuttings was observed when low speeds (1500 rpm) and short durations of centrifugation (10 - 20 min) were used. Higher speeds and longer times usually had a negative influence on the rooting. A tendency for more rooting cofactors and growth inhibitors to diffuse in treatments with high speeds and long periods of the centrifugation was observed in the first three experimentation periods.

Authors: Marczyński Szczepan
Published: June 2015

The defoliants used on shrubs in the nursery were: ethephon, KJ, Mg(ClO3)2•6H2O, CuSO4•5H2O, (NH4)2SO4 in various concentrations separately or as mixtures. Spraying was performed on September 26-28 1972 and 1973. The most effective defoliant for Rosa cv. Lampion, Spiraea X bumalda cv. Froebelii, Spiraea X vanhouttei shrubs was KJ applied at a concentration of 0.2% or used in mixture with ethephon or (NH4)2SO4 in lesser concentrations. Effective defoliation of many shrubs including Forsythia X intermedia was obtained with Mg(ClO3)2 used at a concentration of 0.24-0.48% or CuSO4 at concentration of 2%. But at the same time these defoliants brought about comparatively the greatest retardation in shrubs development and growth and, in the case of Forsythia X intermedia, reducted also frost resistance.

Formowanie powierzchni asymilacyjnej i biomasy przez rośliny buraków cukrowych [Formation of the assimilation area and biomass by sugar beet plants]
Authors: Olech K. , Blamowski Z. K.
Published: June 2015

Measurements were carried out of the assimilation area, NAR value, the crop growth rate (C) and of the yield of roots and leaves of sugar beet plants in a production field during two successive vegetation years. An interdependence was found between the formation of the assimilation area in the canopy and the final yield of biomass. The assimilation area depended mainly on the date of sowing. In 1975, the sowing was earlier by 15 days, amid this resulted in a much more favourable LAI and in a higher yield of biomass. During both vegetation years, a violent decrease of the crop growth rate was observed at the end of August and at the beginning of September. This may be due to an unfavourable change in the ratio of the area of younger, photosynthetically active leaves to older, less active leaves and also to the increased participation of the loss of the assimilates resulting from stronger respiration of the fast growing roots while the photosynthesis of the whole plants decreases.

Authors: Chakraborty Nityananda , Nandi Balen
Published: June 2015

Peroxidase and polyphenol oxidase activities in fruits of two cultivars of banana, 'champa' and 'kanthali' rotted by Botryodiplodia theobromae Pat. was studied. The enzymes showed much higher activities in infected than that in uninfected 'tissues. Increase in peroxidase activity was evidently inhibited by cycloheximide. Polyphenol oxidase activity was also inhibited in presence of phenylthiourea and Na-diethyldithiocarbamate more strongly by the former. Increase in activities seemed to be due to increased sytheses of the enzymes. In an in vitro culture, the fungus exhibited some peroxidase but no polyphenoloxidase activity.
The control of club-root (Plasmodiophora brassicae Wor.) on cabbage seedlings with trifluralin and napropamid herbicides
Authors: Robak J. , Dobrzański A.
Published: June 2015

The herbicides Treflan EC 2 (24% trifluralin) and Devrinol 50 (50% napropamid) applied separately decreased efficiently the incidence of club-root on cabbage seedlings in pot experiments. If these herbicides were applied together with the fungicide Bavistin {50% carbendazim) the control of the disease was in some cases more efficient, as compared with Bavistin used alone. The higher the organic matter content in the soil, the lower the phytotoxicity and dub-root controlling activity of herbicides. Thus, on peat soil the 'herbicides could be applied in much higher rates than on pseudopodsolic soil.

The varieties taking on a bluish hue are characterized by a predominance of flavonols over anthocyanins. The varieties with a stable colour contain both pigments in almost the same amount. The colour change depends also on the amount and kind of anthocyanins.
Porównawcze badania nad występowaniem bakterii w hydroponicznych uprawach sałaty (Lactuca sativa L.) z azotanowaą i amonową formą azotu w pożywce [Comparative studies on the occurrence of bacteria in hydroponic cultures of lettuce (Lactuca sativa L.) enriched with nitrate or ammonia forms of nitrogen in the nutrient medium]
Authors: Kobierzyńska-Gołąb Z.
Published: June 2015

The experiment demonstrated the greatest number of bacteria on the surface of roots immersed in nutrient solution, next on the epidermis of the parts of roots remaining in the air space above the nutrient solution and on the roots growing in the seed-bed; a smaller number in the seed-bed itself and the smallest number in the nutrient solution. The population of bacteria consisted of up to 90% short rod of bacilli. The total number of bacteria in hydroponic culture with ammonium was higher than in that with nitrate. As a rule the bacteria belonging to the separate physiological groups, participating in nitrogen metabolism (ammonifying, proteolytic, proteinizing, denitrifying and oligonitrophilic bacteria) appeared to be more numerus in the culture with ammonium than in that with nitrate. The growth of plants in hydroponic culture with ammonium was weaker than in that with nitrate.
A Precise and Real-Time Loop-closure Detection for SLAM Using the RSOM Tree
Authors: Song Siyang , Xia Shengping , Teng Zhaosheng , Zhang Shuimei
Published: June 2015

In robotic applications of visual simultaneous localization and mapping (SLAM) techniques, loop-closure detection detects whether or not a current location has previously been visited. We present an online and incremental approach to detect loops when images come from an already visited scene and learn new information from the environment. Instead of utilizing a bag-of-words model, the attributed graph model is applied to represent images and measure the similarity between pairs of images in our method. In order to position a camera in visual environments in real-time, the method demands retrieval of images from the database through a clustering tree that we call RSOM (recursive self-organizing feature map). As long as the match is found between the current graph and several graphs in the database, a threshold will be chosen to judge whether loop-closure is accepted or rejected. The results demonstrate the method's accuracy and real-time performance by testing several videos collected from a digital camera fixed on vehicles in indoor and outdoor environments.

Published: June 2015

The higher education establishments, as well as any other organization, seek to survive in an increasingly competitive market. In this scenario, there is a constant concern for improving the quality of life within the work environment whose aim is to keep workers satisfied. Studies show that the degree of worker’s satisfaction at work is directly related to how committed to the organization he is and also these factors could influence the performance of the worker. Therefore both the worker’s satisfaction and the organization commitment are of great importance since these higher education establishments are responsible for promoting the exchange of knowledge through teaching. The objective of the present research is to analyze the relationship between degree of satisfaction and affective commitment organizational of university teachers of the Accounting´s course. The group used on this research was made of by accounting professors of two higher education establishments that hold the highest evaluation grades in Ceará. It was concluded that the satisfaction and the affective commitment have moderate levels of positive correlation between them. In addition, the skills and knowledge related to the work as well as peer relationship are determinant factors of their level of satisfaction within work.

Published: June 2015

This article presents a literature review on quality in tourism services based on journal articles indexed in databases. The documents were selected in fifteen databases, filtered and 105 resulting articles were read and fully evaluated by the method of content analysis. Among the main results are a conceptual matrix for the quality of tourist services and a number of gaps and opportunities for future research. The most significant results are: (1) definition of the causal relationship between service quality and loyalty of the tourist to tourist destination; (2) the literature does not consider the differences between the client of a tour company and the tourist and they deserved treatment differentiated; (3) low theoretical discussion on the issue, which gives scope for further research in the area; (4) research on quality in tourism services is supported by theories of marketing, and require the contribution from other areas of knowledge; (5 ) excessive use of general models for quality measurement, such as SERVQUAL; (6) excess empirical studies with methodological mistakes caused by sampling scientifically inconsistent; (7) quality measurement focused on customer perception and immediate reaction to the event which ignores the multiple elements of the supply chain of the tourism trade.

Musicology, Performance, Slavery: Intellectual Despotism and the Politics of Musical Understanding
Authors: Parmer Dillon
Published: June 2015

This essay focuses on the uneasy relationship between scholarship and performance. I argue that this uneasiness stems from a still pervasive hierarchy, one that gives scholarship the power to regulate, even repress, what musicians themselves know and understand of music through the act of performing. This relation has far-reaching consequences that not only underscore basic epistemological formulations concerning the nature of both music and performance, but also govern what constitutes authoritative knowledge about the art. Indeed, in the modern research university, this relationship effectively accords epistemological legitimacy to every institutional identity that has something to say about music except that of the musician herself. If the musician and her activity figure in, they do so in subordinate positions, as objects to be studied, interviewed, prodded, or measured, or as vehicles for the application of disciplinary or research-based understanding. Such a situation enacts a power dynamic disturbingly similar to those operative in political structures founded on class difference, social inequality, and slavery. Indeed, I trace this dynamic back to Aristotle’sPolitics,where his defence of slavery effectively separates the work of thought from that of the body so as to keep thought elevated and pure. The relevance of this separation to musical matters becomes explicit in Boethian music theory, where those who merely think about music become musical authorities, while those who make music (whether as composers or performers) remain largely ignorant of what they are doing. Excerpts from musicological literature past and present show that this division, what might be called “intellectual despotism,” continues to underwrite institutional music discourse in at least four salient ways: (1) by distorting music from a practice into an object to be observed; (2) by privileging listener-spectatorship and the experience of music had therein; (3) by promoting to sole epistemological authority those who speak to music through the mouthpieces of other disciplinary voices; and finally (4) by constructing musicians as benighted subjects who need to be “educated,” “informed,” or “civilized” by scholarship. The article concludes by outlining a program for undermining this politics, one that places musicians, as well as the knowledge embodied in music-making, at the foundation of musical understanding.

A Study Tour is an opportunity for reflection in a new context. It emphasises experiential learning and offers both group and self-directed activities, enabling participants to explore new territories, cultures and people. It is a transformative reflectivce activity. This paper learns from the case study of a transformative experience for a group of Jamaican teachers and principals crossing the borders and engaging in a UK Study Tour. The evidence illuminates how teachers and principals might cross mental borders and widen their perspectives on the practice and leadership of education through experiential activities, and the ways teachers and principals can integrate new insights gained from crossing a border with existing knowledge from their side of their border. The main purpose of this qualitative reflective case study was to investigate the impact that Study Tours can have. The findings suggest that participants experienced remarkable personal and professional growth which are likely to result in significant changes to their practice and professional identity.
Diversidad familiar y derecho en Chile: ¿una relación posible?
Authors: Cienfuegos Illanes Javiera
Published: June 2015

The objective of this article is to formulate some hypotheses regarding the relationship between Family and Family Law in Chile since the second half of the 20th century. It suggests that family laws are extremely out of touch with respect to the current social reality, because they continue to reproduce a normative ideal of the family. First of all, it presents a theoretical background which questions the idea of the family as a unique, stable and immanent context, and raises the questions of social representation, family diversity and (struggles for) recognition as the main issues for analysis. Secondly, it presents demographic trends regarding the family in Latin America, and points out the gaps in information on the subject. Thirdly, it explores the Chilean caset in detail, taking stock of all the main laws on family matters. Finally, the conclusions point to a gap between the family as it is represented in the law, and its empirical reference points.

Published: June 2015

Existe a concepção social de que os homens possuem maior desempenho em trabalhar no campo das engenharias, da medicina, das ciências políticas e jurídicas, enquanto as mulheres, do magistério, da economia doméstica e do secretariado. Entretanto, as teorizações dos gêneros são consideradas ferramentas utilizadas para indagarem esses “rótulos” naturalizados e cristalizados pela sociedade. Por esse motivo, essa pesquisa baseou-se em Michel Foucault (1978), Stuart Hall (2003) e Bordieu (2005) para se fazer uma reflexão sobre a pouca atuação masculina na área de Secretariado. Para isso, essa pesquisa científica tem por objetivo analisar a linguagem como ferramenta para a construção de ideias e concepções para servir a determinado propósito. Para alcançá-lo, essa investigação orientou-se pelo material de oferta de emprego divulgado no site Catho Online, referente ao período de 29 de janeiro a 23 de março de 2010, pela lei que criou o dia das Secretárias e pelo questionário aplicado aos estudantes e profissionais correlatos à área secretarial. Por último, examinaram-se, no campo da linguagem, os gêneros masculino e feminino para verificar o processo relacional de poder e saber considerando as distinções hierárquicas.DOI:10.7769/gesec.v4i2.171
Nutrient input from the Colorado River to the northern Gulf of California is not required to maintain a productive pelagic ecosystem

The high phytoplankton production (PP) of the northern Gulf of California (NGC) supports a rich biodiversity and fisheries with high yields. The NGC is the habitat of the vaquita (Phocoena sinus), the cetacean most at risk of extinction in the world. The objective of this study is to demonstrate that the NGC is a healthy system at the level of primary producers despite the lack of nutrient input from the Colorado River, and that the small size of the vaquita population is not attributable the collapse of its pelagic ecosystem. Information derived from satellite sensors (CZCS, SeaWiFS, and Aqua-MODIS) was used to explore the possibility of a negative tendency in phytoplankton biomass and PP in the NGC during the last ~35 years. Temporal and spatial variations in sea surface temperature (SSTsat), chlorophyll concentration (Chlsat), and PP were analyzed. Times series were generated for four coastal quadrants, two in the western part and two in the eastern part of the NGC. The NW quadrant covers the vaquita habitat, and it had higher Chlsat and PP values than the others. This may be due to advection of turbid Upper Gulf waters into the NW quadrant. Semiannual and interannual changes in Chlsat and PP occurred, but the seasonal signal was dominant in the whole region. SSTsat maxima occurred in August and September (30–31 ºC) and minima in January and February (16–17 ºC). Chlsat and PP maxima were recorded in March and April (2–3 mg m–3, 2–3 g C m–2 day–1, respectively) and minima in August and September (0.2–0.9 mg m–3, 0.5–1.1 g C m–2 day–1, respectively). These values indicate that the pelagic ecosystem of the NGC is very productive (mesotrophic in summer-autumn and eutrophic in winter-spring).

An important challenge in marine science is to quantify the air–sea flux of carbon because of its possible relation to climate change and the decreasing pH in seawater. In coastal areas of Mexico, the magnitude and variability of carbon fluxes between the ocean and the atmosphere is almost completely unknown. Therefore, the objective of this research was to determine the variability of air–sea carbon fluxes in the upwelling system off northern Baja California. A one-year time series of carbon fluxes was generated from data on partial pressure of carbon dioxide (pCO2) from an oceanographic buoy installed immediately south of Punta Banda (Ensenada, Baja California), which measured salinity, temperature, and pCO2 in the water (pCO2water) and air (pCO2air) every 3 h during 2009. The study area presented several upwelling events with low sea surface temperatures (≤14 ºC), salinity <34.0, and high values of pCO2water, which resulted in an export of excess CO2 in the water to the atmosphere, identifying the area as a temporary source of CO2. In contrast, during the relaxation of upwelling, low values of pCO2water and intermediate surface temperatures resulted in the sea acting as a sink for CO2. The average daily flux was 0.6 ± 0.11 mmol C m–2 in winter, 2.8 ± 0.27 mmol C m–2 in spring, 0.3 ± 0.11 mmol C m–2 in summer, and –0.3 ± 0.03 mmol C m–2 in autumn, the positive sign indicating fluxes from the water to the air and vice versa. The annual balance of CO2 fluxes was 0.3 ± 0.06 mol C m–2 yr–1; thus, the system turned out to be a net source of CO2 from the ocean to the atmosphere.
Dominant modes of variability in large‐scale Birkeland currents

Published: June 2015

Properties of variability in large‐scale Birkeland currents are investigated through empirical orthogonal function (EOF) analysis of 1 week of data from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE). Mean distributions and dominant modes of variability are identified for both the Northern and Southern Hemispheres. Differences in the results from the two hemispheres are observed, which are attributed to seasonal differences in conductivity (the study period occurred near solstice). A universal mean and set of dominant modes of variability are obtained through combining the hemispheric results, and it is found that the mean and first three modes of variability (EOFs) account for 38% of the total observed squared magnetic perturbations (δB2) from both hemispheres. The mean distribution represents a standard Region 1/Region 2 (R1/R2) morphology of currents and EOF 1 captures the strengthening/weakening of the average distribution and is well correlated with the north‐south component of the interplanetary magnetic field (IMF). EOF 2 captures a mixture of effects including the expansion/contraction and rotation of the (R1/R2) currents; this mode correlates only weakly with possible external driving parameters. EOF 3 captures changes in the morphology of the currents in the dayside cusp region and is well correlated with the dawn‐dusk component of the IMF. The higher‐order EOFs capture more complex, smaller‐scale variations in the Birkeland currents and appear generally uncorrelated with external driving parameters. The results of the EOF analysis described here are used for describing error covariance in a data assimilation procedure utilizing AMPERE data, as described in a companion paper.
