Published: May 2019

Synthesis and characterization of Ba1-xLaxFe12O19 based permanent magnet samples with variations in composition (x = 0; 0.02; 0.04; and 0.08) has been done. The method used is a solid state reaction. The phase formation of the sample Ba1-xLaxFe12O19 was carried out at 1200oC for 2 hours. The results of the X-ray diffraction pattern analysis show that all sample compositions have a single phase BaFe12O19. The results of magnetic properties testing using VSM showed that the best coercivity field and remanent magnetization values were obtained at the composition of x = 0.04. The effect of substitution of lanthanum into the barium atom can increase the number of magnetic domains which are indicated by the increase in the coercivity value of the material along with the increasing composition of x. It was concluded that the composition of Ba1-xLaxFe12O19 is a permanent magnet with the best product energy.

Objective. Objective scientific knowledge for many authors more valuable than true subjective belief is determined by research on primary data but a renewed analysis of already recorded or published data is common too. Ever since, an appropriate experimental or study design is an important and often a seriously underappreciated aspect of the informativeness and the scientific value of any (medical) study. The significance of study design for the reliability of the conclusions drawn and the ability to generalize the results from the sample investigated for the whole population cannot be underestimated. In contrast to an inappropriate statistical evaluation of a medical study, it is difficult to correct errors in study design after the study has been completed. Various mathematical aspects of study design are discussed in this article.

Methods. In assessing the significance of a fair study design of a medical study, important measures of publication bias are introduced. Methods of data or publication bias analysis in different types of studies are illustrated through examples with fictive data. Formal mathematical requirements of a fair study design which can and should be fulfilled carefully with regard to the planning or evaluation of medical research are developed.

Results. Various especially mathematical aspects of a fair study design are discussed in this article in detail. Depending on the particular question being asked, mathematical methods are developed which allow us to recognize data which are self-contradictory and to exclude these data from systematic literature reviews and meta-analyses. As a result, different individual studies can be summed up and evaluated with a higher degree of certainty.

Conclusions. This article is intended to give the reader guidance in evaluating the design of studies in medical research even ex post which should enable the reader to categorize medical studies better and to assess their scientific quality more accurately.
Using Ultrasonic Pulse Velocity Test to Assess the Effect of Water-Cement Ratio on the Compressive Strength of Concrete
Authors: Zebari Ziwar
Published: May 2019

This study aims to find the effect of water-cement ratio on the compressive strength of concrete by using ultrasonic pulse velocity test (UPVT). Over 230 standard cube specimens were used in this study, with dimensions of 150mm, and concrete cubes were cured in water at 20 °C. Also, the specimens used in the study were made of concrete with varied water-cement ratio contents from 0.48 to 0.59. The specimens were taken from Diyarbakir-Turkey concrete centers and tested at the structure and material science lab, civil engineering, faculty of engineering from Dicle University.  The UPV measurement and compressive strength tests were carried out at the concrete age of 28 days. Their UPV and compressive strength ranged between (3.89-4.66km/s) and (17.74-40.56MPa) respectively. The experimental results showed that although the UPV and the compressive strength of concrete are related, also, the UPV and compressive strength have a relation with the rate of the water-cement ratio of concrete.

An efficient synthesis of some new chalcone, acetyl pyrazoline and amino pyrimidine bearing 1,3,5- triazine nucleus as potential antimicrobial and antitubercular agent
Authors: Int Chem
Published: May 2019

In an attempt to find a new class of antimicrobial and antitubercular agent, a new series of chalcone, acetyl pyrazoline and amino pyrimidine bearing 1,3,5- triazine nucleus were synthesized with appropriate chemical reagent. Chalcones (D1-D5) were synthesized by the classical Claisen-Schmidt condensation of substituted ketone (C) with variously substituted aldehydes via conventional method. Now treatment of chalcones with hydrazine hydrate/glacial acetic acid and guanidine hydrochloride/Alkali afforded the corresponding acetyl pyrazoline (E1-E5) and amino pyrimidine (F1-F5) derivatives respectively. The chemical structures of all newly synthesized compounds were established on the basis of their FTIR, 1H NMR, 13C NMR, LC-MS as well as elemental analysis. All the newly design compounds were assayed for their in vitro antimicrobial activity against selected pathogens by the Broth dilution method and in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv using Lowenstein-Jensen MIC method. Most of the compounds showed appreciable antimicrobial activity against the all tested strains. Among the synthesized compounds D1, D2, D3, E1, E3, E4, F3 and F4 exhibited excellent antimicrobial activity and said to be the most proficient members of the series. Compound D5 and F5 exhibited promising antitubercular activity.

Modeling of the velocity profile of a bioreactor: the concept of biochemical process
Authors: Int Chem
Published: May 2019

This research covers the modeling of the velocity profile of a bioreactor with recycle; the concept of biochemical process. The biochemical process adopted is fermentation and a plug-flow fermenter (PFF) was taken as a case study. The derivation of workable model equations for monitoring and predicting the velocity profile of a PFF were obtained, together with obtaining the model equations for investigating the effect of microbial and substrate concentrations on the discharge coefficient, bioreactor’s volume. Constant data were sourced from literatures, together with hypothetical values to simulate the derived model equations using Mathlab. The substrate concentration decreases with time as biomass population increases with time. Effect of biomass concentration on discharge coefficient, shows that increase in biomass concentration brings a corresponding increase in the discharge coefficient as well as the bioreactor’s volume revealed that substrate concentration is depleting alongside with bioreactor’s volume follows the same trend of change when substrate concentration is decreasing irrespective of whether the length or area of the bioreactor is varied. The effect of microbial concentration on bioreactor volume when area and length of bioreactor are varied reveals that the process followed same trend only that there is a presence of lag phase upon the influence of inhibitors. The inverse substrate concentration increases, the space velocity also increases, and there is a linear trend of change on the inverse substrate concentration with respect to space velocity.
Assessment of essential and non-essential metals in popcorn and cornflake commercially available in Ethiopia
Authors: Int Chem
Published: May 2019

The levels of essential and non-essential metals in popcorn and cornflake were determined in samples collected from an open market and supermarkets in Addis Ababa, Ethiopia. The samples were mineralized by wet digestion method. The volumes of reagents, digestion temperature and digestion time were optimized after proper sample pretreatment. 1 g of the powdered sample was digested with 10 mL of the mixture of HNO3 (69-72%), HClO4 (60%) and H2O2 (30%) in a volume ratio of 6:2:2 (v/v) for 3 hours at 120 0C on a Kjeldahl digestion apparatus. The levels of metals in the digest were determined by flame atomic absorption spectrometry (for major metals: K, Na, Mg, Ca) and graphite furnace atomic absorption spectrometry (for trace and heavy metals: Cr, Mn, Fe, Co, Ni, Cu, Zn, Pb, Cd). The accuracy of the optimized procedure was evaluated by analyzing the digest of the spiked samples with standard solution and the percentage recoveries varied from 91.2–109%. The level of the metals determined (mg/kg dry weight) were: K 1293±233, Na 148±3, Mg 387±11, Ca 97.9±4.2, Cr 0.68±0.09, Mn (6.17±0.18, Fe 9.5± 2.1, Co 1.41±0.16, Cu 0.09±0.007, Zn 88.3±9.7 and Pb 0.94±0.29 in the popcorn and K 612±70, Na 410±5, Mg 323±11, Ca 196±99, Cr 0.30±0.0.07, Mn 3.0±0.1, Fe 5.5±0.74, Co 0.32±0.03, Cu 0.30±0.01, Zn 40.7±2.5 and Pb 0.36±0.03 in the cornflake while the concentration of Cd and Ni were below the detection limit in both the samples. K and Zn were present at the highest levels among major and trace metals, respectively. The popcorn and cornflake samples purchased from Addis Ababa (Ethiopia) were free from the toxic metals Cd and Ni, but not from Pb.
Physicochemical properties of cross linked acha (digitaria exilis) starch with citric acid
Authors: Int Chem
Published: May 2019

Acha (Digitaria exilis) starch was isolated and crosslinked using citric acid. Physicochemical properties including solubility, water and oil absorption capacities, bulk density, foam capacity, pasting viscosity and granule morphology were determined. Decrease in these properties, except for the emulsion capacity (from 36 to 38%) and least gelation concentration (LGC) which increased from 6% to 8% were observed with modified derivative. General decline was observed with water absorption capacity (488% to 465%); oil absorption capacity (122 to 116%); pH of starch slurry (6.85 to 6.45); bulk density (0.5 to 0.41g/ml) and foam capacity (4.0 to 3.0%).The starch granule morphology was investigated using scanning electron microscopy (SEM). Cross linking may not have affected the shape but appearance and structural arrangements of the starch granules differ upon modification. The starch granules retain its polygonal shape and the granule size ranges between 6um to 8.57 um. The infrared spectra of native acha starch and chemically modified derivative shown similar peaks, except for the additional peak in the cross-linked sample at 1614 cm-1 indicating the carbonyl bands stretching vibrations. Starch utilization as a food or feed relates to its physical and chemical properties. Cross linking altered these functional characteristics. Thus cross linking of Acha starch may find potential applications as good emulsifying agents, pharmaceutical excipients, disintegrants and drug carrier formulation.

Okra fruit (Abelmoschus esculentus L.) especially its mucilaginous properties has been reported to have various health benefits include antioxidant and anti-diabetic properties. This research was aimed to investigate the stability of antioxidant and anti-α-glucosidase activities (as one of antidiabetic activities) of okra mucilage through several soaking treatments in term optimizing mucilage extraction as well. Okra fruit and its peel are used and soaked with water in several soaking conditions: time (1, 4, 8, and 12 h); temperature (room and refrigerator temperature); and ratio of fruit:water (1:3 and 1:6). Analysis of yield percentage, flavonoid content, free radical scavenging activity and anti α-glucosidase activity were observed. The highest antioxidant activity of the sample was found in the extracting methods of 12 h in refrigerator temperature with soaking ratio of 1:6 (897.26+19.67 mg/L) while for anti α-glucosidase activity was found in extracting methods of 12 h in refrigerator temperature with soaking ratio of 1:3 (525.92 ± 40.75 mg/L). The stability of antioxidant and anti α-glucosidase activities of okra mucilage might be influenced by the extracted flavonoid content and other active components.

Published: May 2019

The recent development of nanoscale fillers, such as carbon nanotube, graphene, and nanocellulose, allows the functionality of polymer nanocomposites to be controlled and enhanced. However, conventional synthesis methods of polymer nanocomposites cannot maximise the reinforcement of these nanofillers at high filler content. Approaches to the synthesis of high content filler polymer nanocomposites are suggested to facilitate future applications. The fabrication methods address design of the polymer nanocomposite architecture, which encompass one, two, and three dimensional morphology. Factors that hamper the reinforcement of nanostructures, such as alignment, dispersion of filler as well as interfacial bonding between filler and polymer are outlined. Using suitable approaches, maximum potential reinforcement of nanoscale filler can be anticipated without limitations in orientation, dispersion, and the integrity of the filler particle-matrix interface. High filler content polymer composites containing emerging materials such as 2D transition metal carbides, nitrides, and carbonitrides (MXenes) are expected in the future.

The Action Dynamics of Approach-Avoidance Conflict in Decision-Making: A mouse-tracking study
Authors: Garcia-Guerrero Santiago , O'Hora Denis , Zgonnikov Arkady , Scherbaum Stefan
Published: May 2019

Approach-avoidance conflict is observed in the competing motivations towards the benefits and away from the costs of a decision. The current study employs the action dynamics of response motion, via mouse-tracking, in an attempt to characterize the continuous dynamic resolution of such conflicts. Approach-avoidance conflict (AAC) was generated by varying the appetitive consequences of a decision (i.e., point rewards and shorter participation time) in the presence of a simultaneous aversive consequence (i.e., shock probability). In two experiments, we found that AAC differentially affected response trajectories. Overall, approach trajectories were less complex than avoidance trajectories. As approach and avoidance motivations neared equipotentiality, response trajectories were more deflected from the shortest route to the eventual choice. Consistency in the location of approach and avoidance response options reduced variability in performance enabling more sensitive estimates of dynamic conflict. The time course of competing influences on response trajectories including trial-to-trial effects and conflict between approach and avoidance were estimated using regression analyses. We discuss these findings in terms of a dynamic theory of approach-avoidance that we hope will lead to insights of practical relevance in the field of maladaptive avoidance.
Race-Related Social Contextual Factors, Substance Use, and HIV Among Young Men Who Have Sex with Men in Chicago
Authors: McConnell Elizabeth
Published: May 2019

Black men who have sex with men (MSM), especially young MSM, are more likely to contract Human Immunodeficiency Virus (HIV) than MSM of other races. However, Black MSM consistently report comparable or fewer individual risk behaviors than MSM of other races. Research thus far has largely targeted individual risk factors and has been unable to account for the mechanisms driving this racial disparity. In addition, although individual risk behaviors occur within particular risk environments, little research examining HIV racial disparities has acknowledged that substance use and other HIV risk behaviors are socially and spatially dependent. Emerging research with Black MSM documents racial/ethnic differences in the individual, venue, and neighborhood level networks of young men who have sex with men (YMSM). These findings suggest that although rates of drug use and other individual risk behaviors may be lower among Black YMSM than other racial/ethnic groups, their consequences may be different due to the nature of the risk environments experienced by these young men. The overall objective of this project was to contribute to knowledge about structural mechanisms (e.g., stigma, discrimination, and resource inequality) that shape risk environments, which in turn shape consequences of substance use and other HIV risk behaviors for YMSM of different races/ethnicities. However, quantitative data describing these social and spatial contexts (i.e., the structure of individual, venue, and neighborhood networks) has limited capacity to explore and explain these complex phenomena, and interpreting these data is problematic without the incorporation of the voices, lived experiences, and insights of YMSM themselves. Therefore, thisstudy used an innovative mixed methods approach to visualize and guide the interpretation of individual, venue, and neighborhood level networks captured within an existing NIH-funded cohort of YMSM. Using an explanatory sequential design, multilevel network and geospatial data were visualized (Phase 1) and subsequently used to guide interviews with YMSM (Phase 2). Grounded theory was used to analyze interview data, leading to a theory of mechanisms that shape HIV racial disparities in this population. The overall project had two aims: 1) demonstrate several mechanisms through networks at the individual, venue, and neighborhood levels form risk environments that shape substance use and HIV risk for White, Black, and Hispanic/Latino YMSM, and 2) demonstrate several structural mechanisms, such as stigma, discrimination, and resource inequality, that shape the individual, venue, and neighborhood level networks and risk environments of White, Black, and Hispanic/Latino YMSM.
Rethinking the input: Skewed distributions of exemplars result in broad generalization in category learning
Authors: Carvalho Paulo F. , Chen Chi-hsin , Yu Chen
Published: May 2019

What we learn about the world is affected by the input we receive. Many extant category learning studies use uniform distributions as input in which each exemplar in a category is presented the same number of times. Another common assumption on input used in previous studies is that exemplars from the same category form a roughly normal distribution. However, recent corpus studies suggest that real-world category input tends to be organized around skewed distributions. We conducted three experiments to examine the effects of skewed input distributions on category learning and generalization. Across all studies, skewed input distributions resulted in broader generalization than uniform and normal distributions. Our results not only suggest that the current category learning theories may underestimate category generalization but also challenge the current theories to explain category learning in the real world with skewed, instead of the normal or uniform distributions often used in experimental studies.
Sexuality Through the Lens of Secure Base Attachment Dynamics: Individual Differences in Sexploration
Authors: Selterman Dylan Faulkner , Gesselman Amanda N. , Moors Amy Catherine
Published: May 2019

A key aspect of attachment functioning is the secure base, which empowers people to explore their environments, though some individuals do this more effectively than others. While most researchers have focused on adult attachment dynamics in terms of stress and threat (safe haven), we argue that concerted attention should also focus on relational processes in times of optimal functioning. In this paper, we introduce a new theoretical concept: secure base sexual exploration (or sexploration). We define this as the degree to which individuals are able to effectively explore multifaceted dimensions of sexuality (e.g., behaviors, identity) as a function of secure attachment dynamics. Put another way, we posit that interpersonal attachment security, which is a function of individual and dyadic factors, may meaningfully predict the degree to which individuals are comfortable with sexual exploration. In the first section of our paper, we outline core tenets of attachment theory, followed by an explanation of the secure base construct. We then explain how the secure base construct can be useful in conceptualizing individual differences in sexploration, followed by domain-specific sexual outcomes (e.g., behavior, identity) that may stem from sexploration. Embedded in this discussion is a new approach for researchers to examine these links.
Strengthening the practice and profession of statistics and data science using ethical guidelines
Authors: Tractenberg Rochelle E.
Published: May 2019

This article builds on the concept of disciplinary and professional stewardship, to discuss the ethical practice guidelines from two professional associations and a method that you can learn to use in order to implement those guidelines throughout a professional career. The steward is an individual who practices in a field in a manner that invites and warrants the trust of the public, other practitioners, and employers to uphold and maintain the integrity of that field. It is important to your sense of professional identity - and also your profession - to cultivate a sense of stewardship; and one of the foundational aspects of stewardly behavior is to understand professional practice guidelines and the types of behaviors that are expected by practitioners in a given field. Therefore, this article presents two sets of guidelines that can support professionalism, ethical practice, and the development of a coherent professional identity for the statistician and data scientist. The American Statistical Association (ASA) and the Association of Computing Machinery (ACM) are large professional organizations with international membership. An overall objective of each of these organizations is to promote excellence in and by their members and all those who practice in their respective – sometimes shared/joint – domains. It can be helpful to consider the field of ‘statistics and data science’ to be a hybrid of, or co-dependent on, these two fields, which is one reason why the two organizations are presented together. Another reason is that both organizations take ethical practice very seriously, and both engaged in lengthy projects to carefully revise their respective ethical guidelines for professional practice in 2018. Not only does engagement with the guidelines support you initiating, and beginning to demonstrate, your commitment to this particular professional identity, but also exploring the ethical guidelines for professional practice (through ASA or ACM) is a first step towards documenting your commitment to stewardly work as a data scientist. Ethical reasoning, the third focus of this article, helps deepen the understanding of the guidelines and can be useful to generate evidence of stewardly development.

Differences in Interpersonal Communication Efficacy among Chinese and International Students
Authors: Lu Xintong
Published: May 2019

Within Chinese societies, as in western ones, interpersonal relationships, which can also be called social relations, are one of the most important needs for human beings. Within universities, Interpersonal Communication Efficacy (ICE) has been regarded as having a direct influence on the psychological health of undergraduate students. Based upon the theory of Bandura’s self-efficacy and Xie Jing’s ICE, this article compares the extent of ICE between domestic and international students in a Chinese university. The aim is to identify the similarities and differences between the two research groups, and the implications for the stakeholders (students, teachers, policy-makers, and researchers). A case study was conducted using a questionnaire survey. By employing the methods of quantitative analysis, the questionnaires of 390 respondents were analysed by using variance analysis of SPSS software. The findings of the study reveal that Chinese students are more likely to pay attention to interpersonal communication, and are more interdependent than other international students. This implies the importance of teaching communication skills, improving interpersonal communication efficacy, and understanding teaching and learning across cultures within the ongoing internationalisation of education.

La importancia de Pelagra en el diagnóstico diferencial
Authors: Rojas Chaves Sebastián , Cárdenas Quirós María Fabiola
Published: May 2019

Pelagra es el nombre que se le ha dado a la condición poco conocida, resultado del déficit de vitamina B3 o niacina, una enfermedad potencialmente mortal la cual es caracterizada por una triada clásica de diarrea, dermatitis y delirio, que está asociada a factores de riesgo como desnutrición, pobreza, ingesta de ciertos medicamentos, alteraciones metabólicas entre otros. Pelagra es una enfermedad de diagnóstico clínico que difícilmente se considera en los diagnósticos diferenciales de pacientes que consultan en servicios de emergencias o que se encuentran internados en salones de hospitales y es de suma importancia debido a la mortalidad que conlleva un diagnóstico tardío.

Eğitim sistemlerin amacı, toplumların ihtiyaç
duyduğu ve o toplumun gereklerine uygun bireyleri yetiştirmektir. Öğrenci,
öğretmen ve eğitim programı eğitim sistemlerin önemli üç öğesidir. Bu öğeler
arasında ise öğretmenin ayrı bir yeri olduğunu söyleyebiliriz. Nitelikli
insanların yetiştirilmesi ancak nitelikli öğretmenlerin yetiştirilmesine
bağlıdır. Bu çalışmada dolayısıyla geleceğin öğretmenleriyle
gerçekleştirilmiştir. Bu araştırmanın amaçları, okul öncesi öğretmen
adaylarının yaşadıkları matematik kaygısı ve problem çözme becerileri
arasındaki ilişkiyi belirlemek ve farklı demografik değişkenlerin matematik
kaygısı ve problem çözme becerisi arasındaki ilişki olup olmadığını
incelemektir. İlişkisel araştırma modeline uygun olarak gerçekleştirilen bu
çalışmaya, araştırmaya katılmaya gönüllü 109 ikinci sınıf okul öncesi öğretmen
adayı dâhil olmuştur. Araştırmada katılımcılardan veri toplamak amacıyla Matematik
Kaygı Ölçeği (MKÖ) ve Problem Çözme Becerisi Ölçeği (PÇBÖ) kullanılmıştır. Araştırma
sonucunda katılımcıların demografik özellikleri (Cinsiyet, yaş, liseden mezun
olunan okul türü) ile matematik kaygısı ve problem çözme becerileri arasında
bir ilişkiye ulaşılmazken, katılımcıların problem çözme becerileri ile
yaşadıkları matematik kaygısı arasında istatistiksel olarak anlamlı bir ilişki
söz konusudur. Bu araştırmadan elde edilen sonuçlar mevcut alan yazında elde
edilen sonuçlarla örtüşmekte olduğunu söyleyebiliriz. Araştırma sonucunda elde
edilen bulgular doğrultusunda; hizmet öncesi dönemde okul öncesi öğretmen
adaylarının yaşadıkları matematik kaygısını azaltacak önlemler alınması ve
problem çözme becerilerini geliştirecek çalışmalara bu dönemde yer verilmesi
önerilmektedir.
AĞRI İBRAHİM ÇEÇEN ÜNİVERSİTESİ ÖĞRENCİLERİNİN RUS DİLİ VE EDEBİYATI DERSLERİNDEKİ YAZILI VE SÖZLÜ KONUŞMA ZORLUKLARI

Bugün Türkiye'de, Rus Dili ve Edebiyatı öğrenimine olan ilgi daha çok artmaktadır. Aynı zamanda, Rus Dili ve Edebiyatını
öğrenmek Bağımsız Devletler Topluluğu ülkelerinin temsilcileriyle iletişim kurmak için fırsat verir.

Dilsel olmayan bir ortamda Rus dili ve Edebiyatı öğretiminde (özellikle Türkiye’de), önemli faktörler göz önünde bulundurulmalıdır. Bu, her şeyden önce, eğitim sistemi ve zihniyettir.
Öğrencilerin ulusal-kültürel özelliklerine ve ulusal eğitim sisteminin özelliklerine ilişkin bilgilerinin uygulanması, eğitim sürecinin iyileştirilmesine katkıda bulunacaktır.

Ağrı İbrahim Çeçen Üniversitesi Fen Edebiyat Fakültesinin Öğretmenleri
olarak
Rus Dili ve Edebiyatı derslerinde Türk Öğrencilerin karşılaştığı bazı zorlukları gözlemlediz. Doğal olarak, bu zorlukların üstesinden gelmek için nedenlerini tanımlamadan ortadan kaldırmak imkânsızdır.

Türk
Öğrencilere Rus Dilinin öğretilmesindeki en zor yönlerinden birisinin gramer
olduğu unutulmamalıdır. Bunun dışında ses bilgisi, imla ve kaligrafi de ayrı
bir zorluk teşkil etmektedir. Bu nedenle, Türk öğrencilerle çalışan Rus dili ve
Edebiyatı öğretmenleri olarak yazı yazma gibi bu tür iletişim etkinliklerine
ayrı bir önem göstermeliyiz. Hazırlık sınıfı ve birinci sınıf öğrencilerini Rus
dili derslerinde sözlü yanıtlara alıştırmak gerekmektedir.
HATAY’IN ANAVATANA KATILMASINDAN SONRA BÖLGEYE YÖNELİK DEVLET YATIRIMLARI (1939-1960)
Authors: EDİ AHMET
Published: May 2019

Hatay Türkiye Cumhuriyetine katılmasından sonra bölgeye
yönelik Ankara’nın yatırımları görülmektedir. Özellikle İskenderun Limanını
işlevsel hale getirebilmek için yapılan ekonomik faaliyetler bölgenin
sanayisini olumlu yönde etkilemiştir. Bunun yanında limanın faaliyet alanının
genişlemesi ve önemli ticaret merkezlerinden biri haline gelmesi ile Amik
Ovasında endüstriyel tarımın yaygınlaştığı görülmüştür. Endüstriyel tarım için
gerekli olan ekipmanlar gerek tarım kredi kooperatifi gerek Ziraat Bankası gerekse
Bakanlıklar yolu ile krediler açılarak yapılmaya çalışılmıştır. Bununla beraber
tarımsal verimliliği arttırmaya yönelik sulama noktasında faaliyetlerin olduğu
da görülmüştür. Ekonomik faaliyetlerin özellikle devlet tarafından yapılmasının
yanı sıra özel sektörün de bölgeye yönelik istihdam amaçlı yatırımları da
teşvik edilmiştir. Masrhall yardımları ile başlayan tarımsal reformdan Hatay’da
nasibini almıştır.

1939-1950 ve 1950-1960 arası dönemde iki farklı siyasi
yaklaşımın bölgeye verdiği önem üzerinde de durularak hem karşılaştırmalı hem
de ortak noktadan Hatay’ın durumu değerlendirilmeye çalışılmıştır. II. Dünya
savaşı esnası ve sonrası ile Sovyet tehdidine karşı bölgenin ekonomik açıdan
güçlendirilmesi de çalışmanın bir başka bakış açısı olmuştur. Hatay’a yönelik
yapılan devlet yatırımlarının özellikle bölgenin hassasiyetinden dolayı siyasi
olmuştur.

Çalışmada Amik Ovası ve İskenderun özelinde Hatay’a yönelik
devlet yatırımları Nitel araştırma yöntemiyle incelenerek bölgenin kalkınması
incelenmiştir. Bunun yanında yapılan bu yatırımların siyasi noktada getirileri
ile bölge halkının bakış açısı değerlendirilmiştir. Hassas bir bölge olması
dolayısıyla da yapılan devlet kontrollü gelişmeler incelenmiştir.

Kontestasi Politik dalam Sastra Hikayat “Tjerita Renggan Sedajoe Anak Radja Kota Aboeng (Orang Ampat Lawang)”

The political elite contestation since the the past until now is always interesting to be observed, as we can observe in the Palembang’s manuscripts collection entitled “Tjerita Renggan Sedajoe Anak Radja Kota Aboeng (Orang Ampat Lawang)”, then called TRSARKA. This manuscript shows the political elite contestation in the kingdom of Kota Aboeng Negeri Ampat Lawang, South Sumatra. Contestation among the political elite in the manuscript will be analized with the types of leadership and topos (scenes; repetitive story motives) in the traditional literary work. Colleting data uses the literature review that is sourced from the TRSARKA which is one of the Palembang manuscript collections. The manuscipt belongs to the National Library of the Republic of Indonesia under the script code (Br.157.ixc). By using an analytical descriptive approach, the manuscript of TRSARKA is discussed to find the topos. The results of the topos analysis show that the two models of Traditional Malay leaderships that contradict each other in the TRSARKA, namely trustworthy leadership and betrayal leadership. These two leadership models can be interpreted as features of literary work that always describes the character in black and white. Some topos in the TRSARKA manuscript are royal topoi or a fair and prosperous country, the ideal topoi, betrayal to the king topoi, genealogical topoi, and supernatural power topoi. Sejak dulu hingga sekarang, pertarungan (kontestasi) elit politik selalu menarik untuk dicermati, sebagaimana yang tergambar dalam naskah koleksi Palembang berjudul “Tjerita Renggan Sedajoe Anak Radja Kota Aboeng (Orang Ampat Lawang)”, yang selanjutnya disebut TRSARKA. Naskah ini menggambarkan kontestasi elit politik di Kerajaan Kota Aboeng, Negeri Ampat Lawang, Sumatera Selatan. Kontestasti elit politik dalam naskah ini akan dilihat dari model kepemimpinan dan analisis topos (adegan; motif cerita yang berulang) dalam karya sastra tradisional. Data diperoleh dari hasil kajian pustaka yakni bersumber dari naskah TRSARKA yang merupakan salah satu koleksi naskah Palembang. Naskah ini tersimpan di Perpustakaan Nasional Republik Indonesia dengan kode naskah Br.157.ixc. Melalui pendekatan deskriptif analitis, naskah TRSARKA ini dibicarakan untuk menemukan topos. Hasil dari analisis topos ditemukan dua model kepemimpinan yang saling berkontestasi dalam naskah TRSARKA, yakni kepemimpinan yang amanah dan kepemimpinan yang khianat. Dua model kepemimpinan ini dapat dimaknai sebagai ciri karya sastra Melayu tradisional yang selalu menggambarkan tokohnya secara hitam putih. Adapun topos yang muncul dalam naskah TRSARKA adalah topoi kerajaan atau negeri yang adil dan makmur, topoi pemimpin yang ideal, topoi pengkhianatan kepada raja, topoi genealogis, dan topoi kesaktian.
