Authors: Jiménez Castro Juan David , Díaz Anacona Tania Camila , Meneses Veloza Sonia
Published: March 2018

This research identified and characterized the risks to which the users of the Free University in the Popular Forest are exposed during their journey from their home to the university and vice versa, taking into account the environmental, social and technological risks. For this, a survey was designed to analyze variables such as gender, age, consideration of the road network in its daily route, if it had suffered injuries and / or accidents, among others that were applied to 160 user bicycles. The results indicated that the perception of the risk is greater depends on the place of origin of the user of the bike, that the poor state of the cycle routes increases the perception of risk when committing unsafe acts. The theft is the social risk that most affects the bike users, the environmental risks rain is the one with the highest risk perception and the most relevant technological risk is the mechanical damage.

Authors: Escobar García Diego Alexander , Duque Cañas Juan Pablo , Salas Montoya Andrés
Published: March 2018

This research applies the methodology of supply of transport infrastructure; using GPS devices operational characteristics of the network and current conditions of urban accessibility are determined. It aims to define the most optimal road directions for the Municipality of Riosucio (60.000 inhabitants, Caldas, Colombia). The hypothesis is that with an adequate road direction, mobility features will be improved and this improvement is reflected in a high quality of life for residents. In order to propose changes to the road direction structure, nine (9) accessibility analysis were done: current scenario and eight (8) road direction proposals. Proposals are evaluated from the changes generated on two variables: Average travel time and percentage of covered population. Analyzing the impacts observed in each case, the research defined which proposal will bring more benefits to the municipality.
Comparison of oral, vaginal and sublingual misoprostol for induction of labour in premature rupture of membranes after 34 weeks of gestation: a randomized controlled trial
Authors: Galidevara Chandana , Chaturvedula Latha , Habeebullah Syed
Published: March 2018

Background: Purpose of this study was to evaluate the efficacy and safety of different routes of administration of misoprostol - 50µg oral, 25µg vaginal and 50µg sublingual for induction of labour in women with premature rupture of membranes after 34 weeks of gestation.Methods: Women admitted to labour ward with premature rupture of membranes (PROM) after 34 weeks of gestation and requiring induction of labour were randomized into three groups. A total of 246 women participated in the study and were assigned to three groups to receive either 50µg oral misoprostol (n=80) or 25µg vaginal misoprostol(n=83) or 50µg sublingual misoprostol (n=83). The doses were repeated 4 hourly till active labour was established or up to a maximum of 4 doses. Patient factors, induction to delivery intervals, maternal side effects and fetal outcomes were noted.Results: The mean induction to active labour interval was not significantly different in the three groups (oral vs vaginal vs sublingual-7.52±4.8 vs 7.75±4.1 h vs 7.68±5.3 h; p=0.93). There was no significant difference in the induction to delivery time interval among the three misoprostol groups (oral vs vaginal vs sublingual - 10.9± 5.9 h vs 11.2±5.0 h vs 11.4±6.6 h; p= 0.88). Spontaneous vaginal delivery rate, instrumental delivery rate and lower segment ceasarean section rates were comparable among the three groups. The number of neonates with APGAR score <7 (low APGAR) at 1 minute of birth was highest in sublingual group and lowest in vaginal group which was statistically significant (oral vs vaginal vs sublingual, 16% vs 7.2% vs 20.5%; p= 0. 04). APGAR score <7 at 5 minutes was not significantly different among the three groups (oral vs vaginal vs sublingual, 4.8% vs 2.4% vs 7.2%; p=0.2). This implies that the need for immediate resuscitation was more in the sublingual group. Neonatal intensive care admission was least in the vaginal group although the difference was not statistically significant. Sublingual group had a higher rate of hyperstimulation and fetal heart rate abnormalities compared to oral and vaginal groups although these parameters did not reach statistical significance.Conclusions: Oral, vaginal and sublingual routes of administration of misoprostol are equally effective for labour induction in women with premature rupture of membranes after 34 weeks with sublingual route having slightly higher incidence of low APGAR scores at one minute for the neonate.

Authors: Pathak Varuna , Arya Ruchika
Published: March 2018

Background: Pressures resulting from unrestrained human population growth put demands on the natural world that can overwhelm any efforts to achieve a sustainable future. If we are to halt the destruction of our environment, we must accept limits to that growth. In this hospital based study, we aim to study the factors that influence the choice of contraception. Purpose of this study is to analyze the contraceptive behavior which is a product of many determinants such as age, religion, education, parity, fertility, child care support, economic and social circumstances, motivation, communication and the perception of reliability and safety of a chosen method thereby ensuring better health for the mother and better care and upbringing of children.Methods: The present study entitled effect of male child preference on the decision making of women in choosing contraception is a cross sectional study carried out on 700 subjects in Department of Obstetrics and Gynaecology, Sultania Zanana Hospital, Gandhi Medical College, Bhopal. Study population includes women of reproductive age group who came to seek contraceptive advice from family planning OPD of the hospital.Results: Subjects having 2 male children preferred permanent method of contraception (66%) as compared to subjects having 2 female children (7.93%), this result is statistically significant(p<0.05) showing a strong preference for male child in Indian society.Conclusions: The results indicated that a woman's desire to limit family size with preferred sex composition of children, coupled with her autonomy and the socio cultural context, are the major determinants of contraceptive method choices.

In pluralistic society, democracy has become the best solution for respecting human rights dan giving thefreedom of expression. Normatively, democracy could solve any social-political issues through majorityvoices. Even though, Islam has not mention the term of democracy, its basic tenets teaches thathumankind is equal before God; and it teaches that the nobility of humankind depends on  theirproximity and nearness to God. Islam explicitly forbids the believe in that one nation to claim theirsuperiority than the others. In Islam, syura has the significant role of solving any kinds of problem inliving together.  Thus, democracy in principle did not transgress the Islamic teaching on humanism. Onthe contrary, sectarianism has created negative sentiment and conflict between East and West whichapparently represented by United States and Middle East. Through their sophisticated camouflage theUnited States has accused almost Islamic countries   as the hotspot of terrorism, even thought theirindictment has been factually wrong and misguided.
Melacak perkembangan pemikiran keuangan publik Islam

A major source of revenue for an Islamic state since the days of Umar ibn Khatab and until the decay ofthe Islamic civilization was kharaj and ‘ushr. In this paper a fiscal analysis of this levy will be presentedhighlighting what kharaj and ‘ushr understood by Khalifah Umar and early fuqaha. An Islamic govern-ment is not free to handle public money the way it likes. Public money should be spent judiciously toachieve desired goals. It is a duty of the government in a Muslim state not to squander public moneybut to utilize it to improve living standard of people. Technically, this duty needs to be explaining indetail by fuqaha. Encountered of the Islamic public finance thinking as scattered in Islamic literatureindicate that there is no such “missing link” in the construction of economic science as proposed by thethesis of the great gap, especially in the thoughts of public financial.

La anticorrupción en Colombia, el agente encubierto y la función de inteligencia
Authors: Hernández Gómez José Ricardo
Published: March 2018

El presente artículo tiene como propósito exponer a la comunidad científica la figura del agente encubierto como herramienta anticorrupción. El método descriptivo transversal, sustentado en el análisis de fuentes formales, estructuró la investigación desde una construcción gnoseológica del concepto de corrupción, señalando variados aportes de la jurisprudencia de la Corte Constitucional y enunciando la legislación vigente más relevante, para posteriormente evidenciar las deficiencias de la figura en términos jurídicos y operacionales, su falta de correspondencia con un modelo preventivo, así como la incapacidad de anticipar la comisión de los delitos relacionados con el fenómeno. A partir de las inconformidades, se exploró y propuso la utilización de la función de inteligencia y contrainteligencia como un prototipo anticipativo de excelencia, sustentado en su estructura teleológica y en su devenir histórico.
Análisis crítico del proyecto de ley de creación de las sociedades por acciones simplificadas
Authors: E. Abdala Martín
Published: March 2018

En el poder legislativo argentino se debate la sanción de una ley que crea las sociedades por acciones simplificadas. Se trata de un nuevo tipo de sociedad que, en nuestra opinión de manera errada, se propone crear, mediante una ley independiente y separada de la que regula las demás sociedades, es decir, la ley general de sociedades. La nueva sociedad se caracteriza porque su constitución e inscripción tienen mínimas exigencias (puede ser unipersonal, los capitales mínimos requeridos son exiguos, etc.), porque se aspira a que tenga una estructura de funcionamiento sencilla y dinámica y porque la responsabilidad de los socios está limitada a sus aportes. El objetivo del proyecto es plausible, pero acusa una pluralidad de defectos entre los que, uno de los más importantes, es que el propio proyecto incumple la promesa de simplicidad y propone una regulación alambicada, compleja y rebosante de diferentes aspectos del nuevo tipo societario.
Los desafíos de América Latina para proyectarse como actor regional en el ámbito de la seguridad internacional
Authors: Alda Mejias Sonia
Published: March 2018

En este trabajo se contempla la posibilidad de América Latina para proyectarse como actor regional en el ámbito de la seguridad internacional. Para alcanzar este objetivo, desde una metodología cualitativa, se han contemplado diferentes referencias que se entienden como requisitos necesarios: el proceso de integración subregional o regional y el desarrollo de la cooperación multilateral intra e internacional en el ámbito de la seguridad y la defensa, y la participación de los países latinoamericanos en las misiones internacionales de paz. En la evaluación de cada uno de estos aspectos es evidente la concepción de una perspectiva soberanista, por parte de los países de la región, muy marcada. De ahí que, pese a los avances evidentes logrados, este factor sea un importante obstáculo para los procesos de integración y de cooperación multilateral y, en consecuencia, para la proyección de la región como actor regional, en el ámbito de la seguridad y de la defensa. Sin embargo, considerando la importancia de combatir eficazmente el crimen organizado trasnacional, para América Latina sería trascendental convertirse en un actor regional, a través de los elementos señalados, ya que es la manera más efectiva de combatir esta amenaza.

Authors: Kumar U.T. Sunil , Shrivastava L. Rakesh , Khadse Archana
Published: March 2018

So far little and most likely no previous study had tried to investigate the relationship between Total Quality Management (TQM) practices and organizational performance particularly in post harvest processing of Indian citrus industry. Implementation of quality management in post harvest processing of citrus may take longer time to implement, and requires major changes in cultural aspects as well as stake holder mindset in citrus industry. Leadership, management, finance, organizational culture, skills and expertise are considered as the generic factors critical for the successful implementation within SMEs environment like citrus industry. Judgmental process of grouping similar requirements led to the classification of all these requirements into ten separate categories. Items identified for the purpose of measuring the performance of post harvest processing aspect and the items were clubbed in four categories. In this review paper several new critical factors pertinent to citrus industry have been identified and basic explanation has been provided, which may help in successful implementation of Quality management and contribute to the success of the citrus processing entity.

Authors: Kumawat Narendra , Kumar Rakesh , Singh Mahender , Tomar I. S. , Morya Jagdeesh , Yadav R. K. , Sahu Yogesh Kumar , Singh A. K.
Published: March 2018

Characteristically boro rice is winter season, photo-insensitive, transplanted rice cultivated on supplemental irrigation, often under conditions, where farmers’ are not able to take any other rabi season crop. Butachlor, pretilachlor, bispyribac-sodium and anilofos are the most commonly used herbicides for control of weeds in boro rice. Weed competition is one of the prime yield limiting biotic constraints resulting in yield reduction to the tune of 28 to 45%. Echinochloa spp., Cynodon dactylon, Portulaca quadrifida and Cyperus spp. are the major weeds responsible for yield reduction in boro rice. However, continuous and indiscriminate use of herbicides for a longer period may result in buildup of problematic weeds and also development of herbicide resistance in weeds. It is therefore, necessary to review the performance of promising herbicides for chemical weed management to improve the production and productivity of boro rice under the climate change scenario.
Trichoderma as an efficacious bioagent for combating biotic and abiotic stresses of wheat-A review
Authors: Gangwar O. P. , Singh Akanksha P.K.
Published: March 2018

Several environmental stresses are the major hindrances in achieving the attainable yield in wheat crop. The actual losses due to biotic stresses is estimated in the range of 26-29%, however, abiotic stresses have more adverse effects on crop yield and are responsible for about 70% of yield reduction worldwide. Agrochemicals are widely considered as an effective management strategy for wheat crop diseases and insect pests but they adversely affect the human and animal health due to accumulation of chemical residues in the soil, plant tissues and grains. Hence, there is a need for alternate management strategies to protect crop plants against various stresses. Species of the genus Trichoderma are economically important as biocontrol agents, serving as a potential alternative to agrochemicals for overcoming the biotic and abiotic stresses. The importance of Trichoderma in alleviating the myriad of biotic and abiotic stresses of wheat is discussed in this review article.

Published: March 2018

Increasing yields in agriculture and management of soil fertility are becoming a major issue in view of the malnutrition problems. Tropical ferralitic soils are phosphorus (P)-deficient. The arbuscular mycorrhizal fungi (AMF) must form symbiotic associations with plants to enhance their hydro-mineral nutrition. The objective of this study was to evaluate the effect of mycorhization on growth of Vigna subterranea. Seedlings of two landraces were inoculated withAMF composite (Gigaspora margarita and Acaulospora tuberculata). P was administered by Hoagland solution (0 and 1000 mMPi). Two months after sowing, plants were harvested. The results show that,with or without phosphate, the number of nodules was three times (p less than 0.001) higher in mycorrhized plants compared to controls.Phosphate increased (p less than 0.001) the leaf P-content by 21 and 54% for the control and mycorrhized plants, respectively. Soluble phosphate did not affect the frequency and intensity of mycorhization. Soluble phosphate and mycorhizationsignificantly improve growth and leaf P-content.

Published: March 2018

The Computer gaming addiction is one of the newer concepts that young generations face and can be defined as excessive and problematic use of computer games leading to social and/or emotional problems. The purpose of this study is to analyze through variables the computer gaming addiction levels of secondary school students. The research was conducted with survey and causal-comparative quantitative research methods. Furthermore, it was attempted to contribute to the quantitative data by interpreting the data obtained through open-ended questions. Findings reveal a significant difference between computer gaming addiction and variables of gender, daily gaming times, and whether or not they play games with people they do not know. However, findings did not show any significant difference between computer gaming addiction and variables of grade or purposes of game playing. According to the findings from qualitative data analysis, students mostly prefer to play skill-based games, while they would want to design action games.

Les Obstacles Qui Entravent L’application De L’approche Par Compétences Par Les Enseignants Du Secondaire Qualifiant
Authors: Arbia Abdelali , Kaddari Fatiha , Hour Rida Hajji , Elachqar Abdelrhani
Published: March 2018

Current educational research is almost unanimous on the fundamental role of the competence approach (CA) for effective learning. In fact, on one hand it promotes a better learning, on the other hand it guarantees less stressful conditions for teachers. To be part of this movement, the Moroccan education system adopted this approach since 2000. Since the implementation of this approach can not succeed without the full support of the faculty, where the questions on the origin of this work: have the teachers adopted this approach, as it actually applied, what are their representations on it. To provide some answers to these questions, we have developed a questionnaire that we sent to the 300 teachers of the Secondary Qualifying cycle of several institutions of the Regional Academy of Education and Training of Fes-Boulemane in Morocco. Analysis of this questionnaire using the SPSS software shows that the main obstacles to the application of CA are four. The first obstacle is the low level of the students, the second obstacle is the overload of the programs the third obstacle is the high number of pupils in the classes and the fourth obstacle is the lack of training of the teachers in the CA. Almost half of teachers report that the objectives of applying the competencybased approach are not being met. Hence the need, to operationalize this approach, to act at all levels namely learners, teachers and curricula.

In Albania almost 50% of the household expenditures go for food. The levels of the food have change by years but still have a considered weight in household budget. The study shows the trend and the significant factors that influence the food and non food consumption for different economic levels of the households in Albania. Household composition, geographic characteristics and other material deprivation dimensions have an important impact to the consumption trend and household wellbeing. The data refers to the Living Standard Measurement Survey (LSMS), which measure poverty through expenditures method. It is a multidimensional survey and gives us the possibility to have multi indicators and also disaggregate and test the relationship and influence. This paper shows the trend by household size, for different regions, the typology of the household and other socio-economic factors that may influence the food and non food expenditures trend. It is used the descriptive analyses and quintile regression of different foods level by different factors. The calculations are done using SPSS and Stata.
The Tourism Students’ Awareness of Communicative Competence in an English as a Foreign Language Context
Authors: Anchondo Ercilia Loera
Published: March 2018

The present research aimed to find out the students’ awareness towards the concept of communicative competence and to discover if exposure serves as a tool in the development of the latter. Applying a mixed-method research design, quantitative and qualitative data were gathered with three different instruments: a face-to-face questionnaire, a semi-structured interview, and a structured observation. The subjects consisted of forty-six English as a Foreign Language learners in the intermediate and advanced levels in the Tourism major at the Universidad Autónoma de Ciudad Juárez. Eleven questions were designed to find out the students’ awareness on communicative competence and its components. The interview was based on the elements of communicative competence and the activities related to exposure to the target language. The observation considered details in regards to the students’ performance in the linguistic and pragmatic components of communicative competence. Results indicated that participants are aware of the concept under study and its components. Their answers to the interview and their performance in the observation proposed that exposure to the target language have been used towards the development of certain elements in their communicative competence. Recommendations derived from the present study include making students comprehend what the acquisition of a communicative competence encompasses, which is to manage the target language through the use of the four skills. Secondly, it is of great importance to promote in students the habit of practicing the target language outside the classroom. Finally, it is necessary to pay attention to phonological features such as word stress, pitch, and intonation to improve pronunciation.
Object and Subject Case Marking in Behdini
Authors: Toma Shivan
Published: March 2018

Behdini, a variety of Kurdish, is known to be a morphologically rich language demonstrating both subject and object case marking in an unusual typological distribution. This paper reviews differential object marking (DOM) and differential subject marking (DSM) exemplified by a number of allocated languages, and then DOM and DSM are tested whether they apply on Behdini. This study is designed to answer whether Behdini shows DOM or DSM or whether the way Behdini argument structures are encoded in split ergativity completely governs the case marking of objects and subjects in Behdini. Therefore, ergativity in Behdini is tackled in this study. Data to be applied on Behdini in the process of analysing DOM and DSM are inspired from various studies, and my own linguistic knowledge of Behdini is used for the analysis. The results of the study show that the way split ergativity operates in Behdini entirely accounts for object and subject case marking, concluding that Beddini does not demonstrate DOM and DSM.

Authors: Montagner Ernesto Adrian Diaz , Garcia Juan Carlos Perez
Published: March 2018

Purpose – Conventional materials and procedures in worldwide construction sector is a paradigm that requires change. Constructors usually do not take the adventure of testing novel techniques and materials in their construction projects and, as a result, profits are usually given in terms of time and cost savings. The purpose of this article is to introduce a model to add aggregate value in eco-sustainable dwelling construction through ecological sustainable value chain and hypothesis settlement. Design/methodology/approach - A review of the literature was done in databases using keywords. The selection of sources includes scientific articles and case studies based on different methods and contexts which were carried out. Findings - The findings suggest the implementation of the training of both the employee who works in the construction and the client regarding selfsustainable construction. A significant improvement was obtained based on the commercial relations of suppliers, the client, and also with the construction company. Finally, innovation in at least one of the six proposed aspects was carried out: new technologies, including eco-technologies, the quality of materials (including the eco-sustainable ones), the segmentation of the demand for eco-sustainable housing and its new ways of marketing and financing. They were, however, proposed for added value generation for the development of eco-sustainable housing. Originality/value - A model for the generation of added value in the construction of eco-sustainable housing was elaborated based on the relationships between human and relational capital, training, and the generation of aggregate value.

Behaviours of direct yellow 12 adsorption on mesoporous carbons with different pore geometries
Authors: Liu Fengling , Guo Ziyan , Qiu Hui , Lu Xia , Fang Hua , Ren Jie
Published: March 2018

Four kinds of mesoporous carbons, C1-h-w, C2-h-h, C3-s-w, and C4-s-h, with different pore geometries were prepared and characterised, and their adsorption behaviours with aqueous direct yellow 12 (DY-12) were investigated. The results of X-ray diffraction and transmission electron microscopy show that C1-h-w and C3-s-w have wormlike pore characteristics, whereas C2-h-h and C4-s-h have 2-D hexagonally arranged pores. According to the N2 adsorption/desorption results, the specific surface area of C1-h-w (1,378 m2/g) is the largest among the four carbons. The adsorption isotherms could be effectively fitted using the Langmuir model. The maximum adsorption amounts of C1-h-w, C2-h-h, C3-s-w and C4-s-h are 0.968 mmol/g, 0.726 mmol/g, 0.161 mmol/g and 0.156 mmol/g, respectively. The pseudo-second-order rate constants of C1-h-w (39.8 g/(mmol·min)) and C2-h-h (7.28 g/(mmol·min)) are substantially larger than those of C3-s-w (0.0046 g/(mmol·min)) and C4-s-h (0.014 g/(mmol·min)), indicating that an open and interconnected pore geometry is favourable for DY-12 adsorption. Furthermore, DY-12 diffusion in 2-D hexagonally ordered cylindrical pores is superior to that in wormlike pores due to the smoothness of the channels in the former. External mass transfer and intraparticle diffusion both play roles in the adsorption process.
3D-Printed Patient-Specific ACL Femoral Tunnel Guide from MRI
Authors: Rankin Iain , Rehman Haroon , Frame Mark
Published: March 2018

Background:

Traditional ACL reconstruction with non-anatomic techniques can demonstrate unsatisfactory long-term outcomes with regards instability and the degenerative knee changes observed with these results. Anatomic ACL reconstruction attempts to closely reproduce the patient's individual anatomic characteristics with the aim of restoring knee kinematics, in order to improve patient short and long-term outcomes. We designed an arthroscopic, patient-specific, ACL femoral tunnel guide to aid anatomical placement of the ACL graft within the femoral tunnel.

Methods:

The guide design was based on MRI scan of the subject's uninjured contralateral knee, identifying the femoral footprint and its anatomical position relative to the borders of the femoral articular cartilage. Image processing software was used to create a 3D computer aided design which was subsequently exported to a 3D-printing service.

Results:

Transparent acrylic based photopolymer, PA220 plastic and 316L stainless steel patient-specific ACL femoral tunnel guides were created; the models produced were accurate with no statistical difference in size and positioning of the center of the ACL femoral footprint guide to MRI (p=0.344, p=0.189, p=0.233 respectively). The guides aim to provide accurate marking of the starting point of the femoral tunnel in arthroscopic ACL reconstruction.

Conclusion:

This study serves as a proof of concept for the accurate creation of 3D-printed patient-specific guides for the anatomical placement of the femoral tunnel during ACL reconstruction.
Epidemiology of Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) Related Hepatocellular Carcinoma
Authors: Petruzziello Arnolfo
Published: March 2018

Introduction:

Hepatocellular carcinoma (HCC) is one of the most prevalent primary malignant tumors and accounts for about 90% of all primary liver cancers. Its distribution varies greatly according to geographic location and it is more common in middle and low- income countries than in developed ones especially in Eastern Asia and Sub Saharan Africa (70% of all new HCCs worldwide), with incidence rates of over 20 per 100,000 individuals.

Explanation:

The most important risk factors for HCC are Hepatitis B Virus (HBV) infection, Hepatitis C Virus (HCV) infection, excessive consumption of alcohol and exposition to aflatoxin B1. Its geographic variability and heterogeneity have been widely associated with the different distribution of HBV and HCV infections worldwide.

Chronic HBV infection is one of the leading risk factors for HCC globally accounting for at least 50% cases of primary liver tumors worldwide. Generally, while HBV is the main causative agent in the high incidence HCC areas, HCV is the major etiological factor in low incidence HCC areas, like Western Europe and North America.

Conclusion:

HBV-induced HCC is a complex, stepwise process that includes integration of HBV DNA into host DNA at multiple or single sites. On the contrary, the cancerogenesis mechanism of HCV is not completely known and it still remains controversial as to whether HCV itself plays a direct role in the development of tumorigenic progression.
Speech Acts of Classroom Interaction

Speech acts of classroom interaction have been an interesting topic both in ESL and EFL context. Little research, however, has been held in analyzing speech acts of classroom interaction and its relation to strategies used in EFL context. This paper aims at investigating the types and frequency of speech acts performed in terms of teacher-student interactions. It also focuses on analyzing strategies used by teachers and students in performing the illocutionary act of imperatives. Qualitative method is used by means of mixed pragmatic-discourse approach. The data were collected through observation and recording. Three English teachers and 30 male students grade IX of MTs NW Putra Nurul Haramain are participants for gathering the data. The study reveals that four types of speech acts performed are imperatives, assertive, expressions, and commissives. Of those speech acts performed, the very dominant type of speech acts performed, about 120 acts or 43% is imperatives.  Assertions about 117 acts or 42% are dominant acts.  Expressions about 34 acts or 12% area less dominant category and Commissives about 7 or 2,5% are not dominant. In relation to strategies used in realization of imperatives, the study recognizes that requests as strategies used in realization of request are (a) formal completeness (propositional completeness and modification), (b) level of directness (mood derivable, performative, hedged performative, locution derivable, and conventionally indirect), (c) point of views, (d) context, and (e) mood. The study reveals that imperatives as the most type of illocutionary act performed in classroom interaction. Furthermore, it also indicates the lack of students’ pragmatic competence in performing such an act. For that reason, teachers need to expose the learners with communication strategies in order to speak accurately and appropriately in different context. It needs a further study about pragmatic competence needed in EFL context and material designs for teaching such competences.
Human Resource Competency Tourism Bali together with ASEAN Economic Community
Authors: Brata Ida Bagus , Pemayun A.A. Gde Putra
Published: March 2018

The human resources capacity of Bali tourism is abundant, but in its management is still very far behind with neighboring countries such as Singapore, Malaysia, Thailand, Philippines, and other countries. This is due to the level of education that is still at the level of standards and facilities that are inadequate, resulting in a standard quality of tourism workforce, increased unemployment, decreased productivity, and less competitiveness in the face of competition among tourism workers in the ASEAN region and internationally. Indonesia with the other nine ASEAN member countries have signed the blueprint declaration of the ASEAN Economic Community to initiate an economic integration step. This makes Bali must strive to improve the quality of tourism human resources as well as enhance the competitiveness of tourism workforce in order to survive in the era of ASEAN free trade and globalization of the international labor market. Bali, in particular, should be able to focus and care about the problem of tourism work and immediately clean up to create a conducive climate to accelerate the movement of economic growth through tourism human resources. This can be done by improving education, improving health, conducting training and developing tourism workforce, providing adequate facilities, improving the labor structure, will encourage the quality of Bali tourism workforce to improve. If a country has the competitiveness and is able to compete in the regional and global arena then it can be assured that the tourism worker is able to achieve standardization and have a good reputation and will certainly increase the national tourism human resource index.

Tiempo para coleccionar arte moderno: Colección de arte y sala de exposiciones del Banco de la República de Colombia, 1957-1963
Authors: Mesa Mendieta Alexandra
Published: March 2018

El reordenamiento mundial tras la Segunda Guerra estimula la creación de espacios que favorecen la circulación y el coleccionismo de arte moderno. La Colección de Arte del Banco de la República de Colombia se empieza a gestar en 1957, tras una exposición de lo más reciente del arte colombiano, organizada en la Biblioteca Luis Ángel Arango de Bogotá en el marco del Quinto Encuentro de Bancos Centrales de América.

Las alianzas internacionales que se producen a mediados del siglo XX para concretar vínculos regionales y globales se sirven del arte como un facilitador para la diplomacia. Encuentros de banca y política, suelen inaugurarse con eventos artísticos. Este tipo de prácticas favorece el origen de colecciones y espacios de circulación de arte moderno, que además de representar la filantropía de entidades públicas y privadas, resultan ser piezas clave en el desarrollo y comprensión de los lenguajes artísticos locales y su inserción a circuitos regionales y mundiales.

Objetivo. Evaluar el uso de la Reacción en Cadena de la Polimerasa (PCR) para la detección de Brucella abortus en muestras de sangre y leche de vacunos. Materiales y métodos. Este estudio de tipo descriptivo fue realizado durante los años 2004 y 2005. Se analizaron 136 animales de tres fincas localizadas en el municipio de Durania, Norte de Santander, Colombia. Se evaluó la presencia de anticuerpos en la leche mediante la prueba del anillo (PAL). Se amplifico el fragmento de 223pb del gen BCSP31. Se emplearon los cebadores B4 y B5 de la región interna de la secuencia del gen BCSP31 (GenBank, número de M20404). Resultados. En aquellos animales positivos se obtuvo una muestra de sangre y leche para el análisis por PCR, la sangre no fue analizada por serología. Se evaluaron diferentes métodos de extracción de ADN. Se encontró que un 13.2% (18/136) de las muestras de leche fueron positivas a la PAL. Se analizaron 33 muestras de leche negativas por PAL de las cuales el 30.3% (10/33) resultaron positivas por PCR. Al analizar las muestras de sangre de los animales positivos por PAL el 94.1% (16/17) fueron positivas por PCR, mientras que el 47% (8/17) de las muestras de leche positivas por PAL, fueron positivas por PCR. Conclusiones. Se demostró la amplificación de un fragmento de ADN de Brucella abortus en muestras de sangre y leche de vacunos. Los resultados preliminares demuestran que es posible usar PCR como prueba diagnóstica de brucelosis en Colombia.
The Limits of Sanctions as Instrument for Interest Actualisation in the International System: The Case of North Korea’s Nuclear Weapons Development
Authors: Chukwuemeka (Lecturer) Eze Malachy
Published: March 2018

This paper interrogates the potency of sanctions as US and UN instrument for de nuclearising DPRK and the intervening variables thereof. With the aid of secondary methods of data gathering, content analysis, and rational action theory as framework of analysis, the paper observes that sanctions failed to actualize US and UN goals in denuclearising DPRK. It further observes that this failure is attributed to the absence of most of sanctions enhancing factors in the international system such as weak economy and political instability, quick imposition with decisive maximal impact, and active participation in liberalized trade, tacit coordination of enforcement, of sanctions with manifest political appetite to enforce penalties, lack of capacity to circumvent sanctions, avoiding an overuse of sanctions, weak offshore capital, and immobility of target assets. Therefore, this paper recommends objective international engagement and integration of DPRK as a nuclear state.
