Published: January 2017

In view of the lack of a system of cultural indicators in Riobamba County, the present study develops a series of steps that lead to the obtaining of a list of indicators relevant for the cultural management of the five urban parishes of the county. The data generated by this research will contribute to a general study that intends to rank the city among the 150 most sustainable cities in the world, this will be seen in a future publication as other areas of urban sustainability will be included to determine the integral sustainability of the territory. Initially the research analyzes several models of indicators proposed by organizations and experts understood in the cultural subject at global, regional and local level. We proceed to discriminate these proposed models by looking for their proximity to the local reality. In addition, further information was collected that contributed to generate new cultural indicators of the city through citizen participation. With the help of local authorities, the information collected together was analyzed to determine the indicators that directly affect the level of cultural sustainability of the five parishes in the city. Finally all results are reflected in the publication of a newsletter with statistical summaries where the situation of some cultural aspects of the riobambeña population is reflected in order to make feasible suggestions for improvement and to reinforce the local culture.
Émergence De Taxi-Motos Et Recomposition SpatioÉconomique À Korhogo : Les Taxi-Villes Entre Stratégies D’adaptation Et Désespoir
Authors: Roger Dindji Médé , Abou Diabagaté , Dénis Houenenou Kouadio , Koffi Brou Émile
Published: January 2017

In this article we propose to assess the impact of the taxi motorcycle phenomenon on the functional organization of taxi-cities or taxicars in Korhogo; City in the North of the Ivory Coast. Taking advantage of the temporary banning of taxi-cities at the outbreak of the political-military crisis of 19 September 2002, these two-wheeled vehicles were able to find a place in public transport in Korhogo. Thus obliging the taxi-cities; previously only offering urban mobility, to find strategies of "reconquest". This reflection reveals that the number of taxi-cities has increased from 480 to 86 today. Their receipts have also increased from 11,500 to 6,500 CFA francs per day. In front of the "ground" entirely invested /occupied by taximotorbikes, taxi-cars had to create lines of services distributed on four stations in the city. The merit of this article is to focus on public transport in ivorian secondary cities. In order to do this, the method used is based on observations and land surveys conducted with actors involved in the management of urban transport in three Ivorian secondary cities: Korhogo, Bouaké and Ferkessédougou.

Assessment of Health Related Fitness among Inmates of Reform and Rehabilitation Centers in Jordan
Authors: Al-Shudifat Mahmoud Mousa , Kilani Hashem Adnan
Published: January 2017

The Directorate of General Security in Jordan has created sport fields in new prisons, taking into consideration its importance for inmates. This is due to the belief that prisoners should be encouraged to spend interesting times, discharge their repressed energies, and to improve their physical and mental states in addition to strengthening their social relations. Providing members and specialist officers to attend to the inmates may decrease the problems inside prisons. This, however, can be achieved by engaging them with different kinds of physical activities. The purpose of this study is to evaluate the level of health-related fitness of the inmates in the reform and rehabilitation centers in Jordan and to differentiate between them according to the time span spent in the prison. The study sample consisted of 208 inmates who volunteered to participate in the tests out of 2400 inmates in the center. They were classified into different age categories and their condemnation period. The tests contained the health related physical fitness elements: muscle power, respiratory endurance, muscle strength, flexibility, and body composition in terms of body mass index. Results showed that there were statistical differences between the categories in this study in some tests. In conclusion, inmates should undergo physical programs to prevent them from contacting non-communicable diseases due to hypokinetic and sedentary life.
L'enfermement Identitaire Dans Le Cinema Marocain Moderne
Authors: Bouyahya Adil
Published: January 2017

This article analyses the Moroccan cinema during the period (1990- 2000) since it focuses on a central issue of its discursive and esthetic unity. Thus, the article addresses the question of confinement. In other words, in this paper we seek to reflect on the unifying desire and the confined collective identity. In fact, this cinematography deals mainly with a quasiarchaic Moroccan society which is confined in the rigidity of an Arab- Islamic identity. Besides, we adopt am esthetic scenographic approach to delineate the Moroccan society's imprisonment within the borders of immutable values. In this paper, the main protagonists in the movies under scrutiny do not enjoy their status as modern heroes; on the contrary, they only access this role when they are deemed as desire objects in quest for a space of freedom and liberty.

Published: January 2017

The purpose of this paper is creating distinctive value proposition and recognizable destination brand through integration of different activities and actors in the segment of tourism by application of a business model tool. To illustrate the application of the “Business model canvas” tool, it was taken a case study of the city of Ohrid, which is one of the most beautiful tourist destination on the Balkan Peninsula, protected by UNESCO, but at the same time confronted with many problems in tourism, as many tourist destinations in the world. Besides, the application of the methodology of “business model canvas”, we carried out interviews and an empirical survey on “creators” and “consumers” of tourism in the city of Ohrid. The results of the overall research, the created tourist model of Ohrid, as well as the supported research instruments, interviews and empirical survey bring some interesting ideas and solutions for many contemporary issues in tourism, such as: integrated tourist offer that lasts 12 months, combined with diverse types of tourism, highly professional service and shared values, widely differentiated accommodation with clear targeting and positioning strategy, as well as focused tourist zones that cover certain type of tourism for a pleasant stay and experience e of tourists with necessary supporting services for the full functionality. The main idea is the wide diversity of offers to be integrated into one story, supported from citizens as well as from all key partners who believe in the city brand called Ohrid.

Cuerpo y subjetivación: elementos para una lectura de conflictos escolares
Authors: Yuing Alfaro Tuillang , Godoy Peña Lorena
Published: January 2017

El texto explora posibilidades para pensar conflictos de la realidad educativa, tomando como ejemplo las movilizaciones chilenas del 2006. Para ello recurre a los aportes de Foucault sobre poder e institucionalidad: en la escuela, el cuerpo del alumno se ha convertido en objeto de apropiaciones y tensiones. A través de regulaciones y evasiones, se manifiesta un litigio identitario entre la escuela y aquella juventud que busca convertirse en subjetividades que toman la palabra de manera crítica.De este modo, el texto pregunta ¿cuál ha sido el rol de estos procesos identitarios y subjetivación en la gestación de las movilizaciones estudiantiles? ¿Qué oportunidades presentan éstas pugnas para la elaboración de prácticas pedagógicas que respondan a modelos distintos al panorama político-escolar presente? Finalmente, se elabora una interpretación de las nociones de experiencia e infancia a partir de Giorgio Agamben, con el fin de ensayar algunas hipótesis en torno a estas interrogantes.

Authors: Rivero Franyutti Agustín
Published: January 2017

El presente artículo investiga el caso de la palabra tepuzque (cobre en náhuatl) como un ejemplo de préstamo transitorio en el habla de los conquistadores españoles. En él, se estudian, a través del testimonio de Bernal Díaz del Castillo, que las registró en su crónica, acepciones que no están incluidas en ninguno de los diccionarios de mexicanismos actuales. Para detallar los referentes de dichas acepciones, se incluye información histórica sobre las monedas y los cañones en el siglo dieciséis (tepuzques para los españoles), y, en la segunda parte, se lleva a cabo un análisis lingüístico enfocado en los cambios fonéticos, morfológicos y semánticos que sufrió la palabra primero como préstamo del náhuatl al español y después a las relaciones semánticas entre las acepciones que tuvo en español.

Authors: Ivanova-Petropulos Violeta , Tašev Krste , Stefova Marina
Published: January 2017

A solid-phase extraction method followed by reverse phase high-performance liquid chromatography (RP-HPLC) was optimized and validated for the quantitative determination of tartaric, malic, shikimic, lactic, citric and succinic acids in wine. Solid-phase extraction was carried out with C18 cartridges and extraction recoveries for all acids ranging from 98.3 to 103% were obtained. HPLC separation was performed with isocratic elution on a LiChrosorb RP-18 column (250 × 4.6 mm I.D., 5 µm) protected with the appropriate guard column. The mobile phase was a 5 mM solution of H3PO4 with pH 2.1 at a flow rate of 1 ml/min. Detection of the organic acids was performed at 210 nm. The developed method was validated by checking its linearity, limit of detection (LOD), limit of quantification (LOQ), precision and recovery. The method was applied to the analysis of organic acids in Macedonian red and white wines.

Published: January 2017

In this study, 4-[(4-methyl-5-phenyl-4H-1,2,4-triazol-3-yl)sulfanyl]benzene-1,2-dicarbonitrile was synthesized and its molecular structure was characterized by means of FT-IR and X-ray diffraction methods. The crystal is monoclinic and belongs to the P21/n space group. There are three weak intermolecular C-H…N type hydrogen bonds in the molecular structure. The geometrical parameters, vibration frequencies, HOMO–LUMO energies, and molecular electrostatic potential (MEP) map of the compound (3) in ground state were calculated by using density functional theory (DFT/B3LYP) with the 6-311G(d) basis set. Calculated geometrical parameters were compared with X-ray diffraction geometric parameters. On the other hand, theoretical and experimental FT-IR results were also compared.
Optimization of Microwave-assisted Extraction of Thymoquinone from Nigella sativa L. Seeds
Authors: Karacabey Erkan
Published: January 2017

The high potential of thymoquinone as an ingredient and/or additive in the food, pharmaceutical and cosmetic industries has been well established in previous studies. However, its extraction from natural sources was considered in the limited studies and none of them included the microwave-assisted extraction (MAE) of a thymoquinone-rich extract and process optimization. In the present study, this high-value-added bioactive was aimed to extract from its well-known natural source, black cumin seed (Nigella sativa L.), using methanol as a solvent for all of the studied extraction methods. For extraction of a compound of interest, microwave-assisted extraction system having temperature controlling function was used and its performance was compared with common extraction methods, Soxhlet and conventional solid/liquid extraction. The results indicated that the MAE system provided a rich extract containing thymoquinone, which was 2 and 7 times higher than those produced by conventional solid/liquid extraction and Soxhlet, respectively. Influences of temperature, time and solvent/solid ratio on thymoquinone yield were investigated for MAE. The solvent/solid ratio was found to have the main effect on extraction performance, whereas an interaction effect of temperature and time was significant. Variables of MAE were optimized by response surface methodology to produce a thymoquinone-rich extract. Optimal conditions for the highest yield of thymoquinone were determined as 10 minutes extraction at 30 °C, using 30 ml solvent per gram of black cumin seed. The estimated thymoquinone yield of the extract was 628 mg/kg black cumin seed. It could be concluded that the currently optimized MAE with temperature controlling function is a promising technique to produce a thymoquinone-rich extract from black cumin seeds.
Mineralogical and geochemical characteristics of particle PM10 in Tikveš area and their infuence in the environment
Authors: Boev Ivan , Stafilov Trajce
Published: January 2017

In this work the results of investigation of the geochemical and mineralogical characteristics of particulate matters below 10 μm (PM10) collected from Tikveš area, Republic of Macedonia, are presented. For that purpose, PM10 samples were collected from the city of Kavadarci and from the area close to the ferronickel smelter plant. As well as the concentration of PM10, the chemical content and mineral phases of dust samples and their relations to some anthropogenic sources are investigated. Determination of the content of various elements was performed by using inductively coupled plasma–mass spectrometry (ICP-MS). Scanning electron microscopy–energy dispersive spectroscopy (SEM-EDS) was used for the determination of mineralogical phase content. From the obtained results, it can be concluded that the concentration of PM10 in the vicinity of the ferronickel smelter is much higher than those from the city of Kavadarci. It was found that PM10 samples collected close to the ferronickel smelter plant have a higher content of some elements present in higher concentrations in the ore processed in the ferronickel smelter plant (Fe, Ni, Cu, Zn, Ag, Cr) than those from the town of Kavadarci, showing their anthropogenic origin. The investigations performed by applying electron microscopy (SEM-EDS) unequivocally confirmed the results obtained using X-ray diffraction and ICP-MS. Namely, mineral phases present in the particulates were found to be those which are present in the ore used in the process in the metallurgical plant, including chlorite, amphibole, pyroxene, magnetite, chromites, quartz, calcite or plagioklas clay minerals.

Thermodynamics of a Set of Closed Curved Surfaces and Noether’s Theorem
Authors: Hollestelle Harmen
Published: January 2017

For a set of closed curved surfaces that resemble a Langmuir monolayer an energy is defined that depends only on the curvature of the surfaces interacting with the dimensions normal to the surfaces, that is, the thickness of these surfaces. The thickness, or depth, of the surfaces originates because of surface-particles with chains, that move freely on the inside of the surfaces at a certain depth. This is a purely geometrical description that does not depend on the introduction of ad hoc constants like the elastic constant. With a statistical mechanical model the equations of state are calculated for a gas of non-connected sphere-like surfaces in a volume. There are two states of which the lower temperature state is depending mostly on the interaction energy and surface properties, and the higher temperature state is depending mostly on sphere kinetic and volume properties. This results in aggregation of the sphere-like surfaces from many small ones to few large ones when lowering temperature and vice versa. The model allows for the calculation of the partition function and, when the emergence of the curvature - depth interaction is described as a phase-transformation, for the application of Noether’s theorem. Because of these properties the model is interesting in its own right apart from being an addition to existing elastic descriptions of surfaces.
Constructivist Methods in Teaching: The Case for Albania
Authors: Nela MSc. Alfred
Published: January 2017

In the previous century many theories were created for the teaching.  One of them is the constructivist method widely used. The focus of constructivist theory is oriented towards the pupil. It presupposes that the environment of learning should provide view points or different interpretations of reality, building knowledge, wealth content, and activities that are based on experience. Constructivism is focused on lore and knowledge and not in mechanic imitation of subject content. It is based on a persuasion that the person builds his lore based on his experience, mental structure and faiths used for interpretation of objects and phenomena. The mind is used like an instrument in the interpretation of the event, goals and prospects because they are personal and individual.The main goal of the survey is the coverage and elaboration of some theoretical and practical views, reported from a considered number of research examples about constructivist methods and an actual analysis of Albanian educational system. As a research methodology we have exploited quantitative data. National and international surveys are used, dedicated, to the evaluation of Albanian Pre-university educational system.In the last decadeAlbania, started adopting some reforms in the teaching methodology. Some experts in educational field published some textbooks and manuals about constructivist methods. Prior to these reforms in the field of teaching, policy making bodies approved ordinance and legal drafts in adjustment of this methodology. But even after these reforms, the Albanian educational system is behind the regional education system in regards to the achievements of pupils. The lack of specific training of educational staff, non-adaptation of educational software, inappropriate physical infrastructure of schools, the lack of technical equipments hamper the practicability of this method. Another aspect is insufficient financial budget dedicated to education. Albanian school is also guided and managed by leaders and teachers that follow traditional methods in teaching and administration.
Agroecologist Education for Sustainable Development of Farming and Food Systems
Authors: Francis C. A. , Jensen E. S. , Lieblein G. , Breland T. A.
Published: January 2017

Core Ideas

Ecological principles are applied in design of future farming systems.

Close working relationships with farmers and other stakeholders are essential to education.

Educational programs will develop autonomous and social learners.

Local food systems provide an alternative to growing globalization of food.

Graduate study in agroecology prepares students for responsible action in the future.

Twelve educational strategies for future agroecologists are based on experiences in Nordic universities, with priorities informed by six propositions about future resource challenges. The principal objective is student learning for future challenges and contributions to sustainable development of farming and food systems, including practice in acquiring capacities needed for responsible future action. The heart of the program is learning to apply ecological principles in design of farming and food systems, using multi‐criteria evaluation for prioritizing sustainability challenges, and measuring ex‐ante success of transition. Working closely with farming and food system stakeholders in design and implementation of learning environment is essential, plus recognizing contributions of farmers and food system professionals as vital to education for design of future systems. Holistic approaches integrate multiple disciplines, and combine technologies developed through science with those discovered in the field. Students’ prior experiences also contribute to activities in the learning landscape, and important skills are developed for autonomous and lifelong learning. Practices from organic farming and other alternative farming strategies provide useful examples, and local food systems represent one viable option that can potentially reduce food distance and food waste, and thus contribute to food security and food sovereignty. Capacities to deal with difficult challenges are developed by each student in agroecology and related courses, including observation, participation, reflection, dialogue, and visioning. These capacities are applied while completing a thesis project using natural science and social science methods that affirm their skills and prepare students well for responsible action in a complex and uncertain future.

Cover crops retain post‐harvest nutrients but how they impact non‐growing season nitrous oxide (N2O) emissions is unclear. Therefore, we quantified how cover crop type (fall rye [Secale cereale L.] or oilseed radish [Raphanus sativus L.]) and fertilizer source (compost or inorganic fertilizer) affected N2O emissions, soil water‐extractable organic C (WEOC) and nitrate (NO3) dynamics over two non‐growing seasons. A treatment with no fertilizer or cover crop was also included. Weekly, N2O fluxes were determined using vented static chambers; soil WEOC and NO3–N concentrations were measured monthly. Each non‐growing season, mean N2O fluxes were 74 to 450% greater in the winter (21 December–20 March) than spring (21 March–20 June) or fall (22 September–20 December). In winter 2014–2015, oilseed radish increased the mean N2O flux by 39 and 323% compared with fall rye and no cover crop, respectively, while the mean N2O fluxes were strongly correlated to the pre‐winter (16 Dec. 2014) NO3 concentrations (r = 0.96; P < 0.001), indicating NO3 levels < 6 mg NO3–N kg–1 limited N2O fluxes. In 2014–2015, fall rye and oilseed radish had 76 and 154% greater cumulative N2O emissions than amended soils with no cover crop, respectively. Across both winters, an exponential model explained 67% of variability between the pre‐winter WEOC to NO3 ratio and N2O fluxes, indicating that organic C and NO3 controlled over‐winter N2O fluxes. Non‐legume cover crops increased non‐growing season N2O emissions, suggesting that cover crops concentrate denitrification substrates in root‐associated soil to enhance N2O fluxes.

Toxocariasis is an extensive helminthic infection that leads to visceral larva migrans in humans. A 2.5-year-old girl referred for abdominal mass. She had history of pharyngitis for two weeks. There were no other symptoms. Abdominal examination revealed an irregular solid mass in right lower quadrant (RLQ). Abdominal ultrasonography revealed an echohetrogenic large mass in RLQ, liver, and retroperitoneal area. Abdominal CT scan showed a huge mass. At laparotomy a large retroperitoneal mass that involved right liver lobe, bladder, ileocecal valve, small and large intestines was found. At histopathology diagnosis of toxocariasis was made.

Published: January 2017

Foreign body (FB) ingestion is a common problem in children. Prolonged impaction of FB in esophagus may result in tracheoesophageal fistula (TEF). A 6-year-old girl presented with progressive dysphagia and recurrent chest infections. No history of FB ingestion was given by parents. Further investigations revealed FB (spool) in cervical esophagus. Patient was successfully managed by surgery through trans-cervical approach.
A DC Voltage Control Strategy for Active Power Filter
Authors: Cao Xudong , Zhou Shaozhe , Li Jingze , Zhang Shaohua
Published: January 2017

Active Power Filter (APF) is capable of changing the size and frequency of harmonics as well as changes in reactive power compensation. It is important to control the stability of the DC-link capacitor voltage stability for it. For DC voltage controls of APF, there are two important achievements. First, it is indicated that the control of DC voltage directly affects the compensation performance of APF. Second, the value of DC voltage influences the power loss of APF. This paper firstly introduces the design of the DC voltage controller. Then the relationship between DC voltage and the power loss as well as the compensation performance of APF is analyzed. Finally, a new control scheme with a droop controller is developed to regulate DC voltage.
Metacarpophalangeal Joint Arthrodesis of the Thumb – Minimum of Eight Months Follow-up
Authors: Jørgensen Rasmus Wejnold , Brorson Stig , Jensen Claus Hjorth
Published: January 2017

Background:

Disorders of the thumb metacarpophalangeal (MCP) joint can lead to significant loss of function and pain. Thumb MCP arthrodesis following traumatic injuries is inadequately described and recent studies have questioned the outcome of this treatment.

Purpose:

The purpose of this study was to report outcome and disability following thumb MCP joint arthrodesis in the treatment of chronic instability after traumatic injuries.

Methods:

A retrospective review of 26 patients operated on with MCP joint arthrodesis, median follow-up 42 months (8-104months). Subjective outcome was assessed using the disabilities of the Arm, Shoulder, and Hand-questionnaire (DASH). In addition, patient satisfaction, pain, stiffness, and impairment of activities of daily living were assessed on a Visual Analogue Scale (VAS) followed by a question stating whether they would undergo the same procedure again.

Results:

Two patients (7.7%) needed re-operation due to nonunion. Four patients (15.4%) needed hardware removal. Median DASH-score was 18 (25-75% range 6-47), with lower DASH scores being better. Scores were significantly worse in gender and age matched individuals (p<0.05). Median VAS for pain was 3.7 (range 0-8). More than 50% of patients reported mild, moderate or severe pain, but all patients reported that they were willing to undergo the same procedure again.

Conclusion:

Our data suggest, that patients with post-traumatic thumb injuries managed with thumb MCP joint arthrodesis perform worse than gender and age matched individuals. Many lived with pain, but all reported that they were willing to undergo the same procedure again. We suggest that the disability scale by the National Board of Industrial Injuries should be reconsidered for patients operated on with thumb MCP arthrodesis.
The Logic of Latent Variable Analysis as Validity Evidence in Psychological Measurement
Authors: Baghaei Purya , Tabatabaee Yazdi Mona
Published: January 2017

Background:

Validity is the most important characteristic of tests and social science researchers have a general consensus of opinion that the trustworthiness of any substantive research depends on the validity of the instruments employed to gather the data.

Objective:

It is a common practice among psychologists and educationalists to provide validity evidence for their instruments by fitting a latent trait model such as exploratory and confirmatory factor analysis or the Rasch model. However, there has been little discussion on the rationale behind model fitting and its use as validity evidence. The purpose of this paper is to answer the question: why the fit of data to a latent trait model counts as validity evidence for a test?

Method:

To answer this question latent trait theory and validity concept as delineated by Borsboom and his colleagues in a number of publications between 2003 to 2013 is reviewed.

Results:

Validating psychological tests employing latent trait models rests on the assumption of conditional independence. If this assumption holds it means that there is a ‘common cause’ underlying the co-variation among the test items, which hopefully is our intended construct.

Conclusion:

Providing validity evidence by fitting latent trait models is logistically easy and straightforward. However, it is of paramount importance that researchers appreciate what they do and imply about their measures when they demonstrate that their data fit a model. This helps them to avoid unforeseen pitfalls and draw logical conclusions.

Published: January 2017

Sin lugar a dudas, Veracruz es uno de los estados más ricos del país, tanto por sus recursos naturales, como por sus manifestaciones culturales. En este contexto, y de acuerdo a los lineamientos del Plan Nacional de Desarrollo y el Plan Nacional de Ecología, el CICOLMA se establece como un centro cuyos principales objetivos son: 1) promover la investigación multidisciplinaria en zonas costeras, tanto básica como aplicada, con un especial énfasis sobre la relación entre ecosistemas terrestres y costeros, y 2) apoyar la enseñanza de los procesos y patrones que ocurren en estos ecosistemas, a través de cursos y seminarios. En el CICOLMA se pretende conservar y estudiar un sector representativo de los ecosistemas costeros del estado de Veracruz, con el objeto de consolidar un espacio geográfico de trabajo para la investigación científica y tecnológica, que dé garantía de continuidad a los proyectos, a los investigadores y a las instituciones estatales y nacionales que realizen estudios en la zona.El CICOLMA es uno más de los centros regionales de investigación del Instituto de Ecología. Cuenta con una superficie de 70 ha, 48 de las cuales corresponden a un área forestal, perteneciente al gobierno estatal (bajo la custodia del Centro) y 22 más propiedad del Centro, en donde se asientan las presentes instalaciones, así como parcelas destinadas a la investigación agropecuaria.En esta extensión relativamente pequeña, se ha realizado y continua realizándose, una gran cantidad de investigaciones cuyos resultados podrán ser extrapolados a otras zonas costeras del estado y del país. Como ejemplo, tenemos los estudios sobre especies fijadoras de dunas, llevadas a cabo por la Dra. P. Moreno Casasola desde hace más de 10 años. Por otro lado, el área de influencia del Centro es bastante extensa, pues incluye la cuenca hidrológica que drena parte del extremo este del Eje Neovolcánico Transverso.
