Opioid-receptor activation in cell lines results in phosphorylation of p42/44 mitogen-activated protein kinase (MAPK), which contributes to agonist-induced desensitization of adenylate cyclase signaling. In this study, morphine-induced MAPK modulation was examined in the mouse brain using antibodies against phosphorylated MAPK. Thirty minutes after systemic morphine, MAPK modulation was observed in brain areas associated with analgesia and reward. Activation of MAPK was increased in the anterior cingulate (Acc), somato-sensory and association cortices, and locus ceruleus (LC). In contrast, MAPK activation was decreased in the nucleus accumbens and central amygdala (CeA). Double-label confocal microscopy revealed that morphine-induced MAPK modulation occurred predominantly in cells not expressing μ-opioid receptors, with the exception of the LC. Furthermore, the NMDA receptor antagonist 3,3-(2-carboxypiperazine-4-yl)-propyl-1-phosphonate blocked morphine-induced MAPK modulation in several cortical areas including the Acc. We then examined morphine-induced MAPK modulation during expression of either analgesic tolerance or locomotor sensitization, which were differentiated by two repeated morphine regimens. Analgesic tolerance was accompanied by tolerance to morphine-induced MAPK modulation in all of the brain areas examined except the CeA. Locomotor sensitization resulted in sensitization to morphine-induced MAPK activation in the posterior basolateral amygdala. Additionally, a pronounced instatement of morphine-induced MAPK activation was observed in CA3 hippocampal processes. This instatement was observed during expression of tolerance; however, it was not significant during sensitization. In summary, these results provide distinct, region-specific mechanisms for morphine-induced MAPK modulation in the mouse brain and give insight into the brain circuitry involved in acute and adaptive opioid behaviors.

BCL-2 family proteins are known to regulate cell death during development by influencing the permeability of mitochondrial membranes. The anti-apoptotic BCL-2 family protein BCL-xL is highly expressed in the adult brain and localizes to mitochondria in the presynaptic terminal of the adult squid stellate ganglion. Application of recombinant BCL-xL through a patch pipette to mitochondria inside the giant presynaptic terminal triggered multiconductance channel activity in mitochondrial membranes. Furthermore, injection of full-length BCL-xL protein into the presynaptic terminal enhanced postsynaptic responses and enhanced the rate of recovery from synaptic depression, whereas a recombinant pro-apoptotic cleavage product of BCL-xL attenuated postsynaptic responses. The effect of BCL-xL on synaptic responses persisted in the presence of a blocker of mitochondrial calcium uptake and was mimicked by injection of ATP into the terminal. These studies indicate that the permeability of outer mitochondrial membranes influences synaptic transmission, and they raise the possibility that modulation of mitochondrial conductance by BCL-2 family proteins affects synaptic stability.

Cocaine addicts display increased sensitivity to drug-associated cues, due in part to changes in the prelimbic prefrontal cortex (PL-PFC). The cellular mechanisms underlying cue-induced reinstatement of cocaine seeking remain unknown. Reinforcement learning for addictive drugs may produce persistent maladaptations in intrinsic excitability within sparse subsets of PFC pyramidal neurons. Using a model of relapse in male rats, we sampled >600 neurons to examine spike frequency adaptation (SFA) and afterhyperpolarizations (AHPs), two systems that attenuate low-frequency inputs to regulate neuronal synchronization. We observed that training to self-administer cocaine or nondrug (sucrose) reinforcers decreased SFA and AHPs in a subpopulation of PL-PFC neurons. Only with cocaine did the resulting hyperexcitability persist through extinction training and increase during reinstatement. In neurons with intact SFA, dopamine enhanced excitability by inhibiting Kv7 potassium channels that mediate SFA. However, dopamine effects were occluded in neurons from cocaine-experienced rats, where SFA and AHPs were reduced. Pharmacological stabilization of Kv7 channels with retigabine restored SFA and Kv7 channel function in neuroadapted cells. When microinjected bilaterally into the PL-PFC 10 min before reinstatement testing, retigabine reduced cue-induced reinstatement of cocaine seeking. Last, using cFos-GFP transgenic rats, we found that the loss of SFA correlated with the expression of cFos-GFP following both extinction and re-exposure to drug-associated cues. Together, these data suggest that cocaine self-administration desensitizes inhibitory Kv7 channels in a subpopulation of PL-PFC neurons. This subpopulation of neurons may represent a persistent neural ensemble responsible for driving drug seeking in response to cues.

SIGNIFICANCE STATEMENTLong after the cessation of drug use, cues associated with cocaine still elicit drug-seeking behavior, in part by activation of the prelimbic prefrontal cortex (PL-PFC). The underlying cellular mechanisms governing these activated neurons remain unclear. Using a rat model of relapse to cocaine seeking, we identified a population of PL-PFC neurons that become hyperexcitable following chronic cocaine self-administration. These neurons show persistent loss of spike frequency adaptation, reduced afterhyperpolarizations, decreased sensitivity to dopamine, and reduced Kv7 channel-mediated inhibition. Stabilization of Kv7 channel function with retigabine normalized neuronal excitability, restored Kv7 channel currents, and reduced drug-seeking behavior when administered into the PL-PFC before reinstatement. These data highlight a persistent adaptation in a subset of PL-PFC neurons that may contribute to relapse vulnerability.
Differential Expression of Histone H3.3 Genes and Their Role in Modulating Temperature Stress Response inCaenorhabditis elegans

Histone H3.3, a major variant of canonical histone H3, is highly conserved and essential for viability or fertility in most lineages. In Caenorhabditis elegans, H3.3 is expressed from five genes. Here, Delaney...

Replication-independent variant histones replace canonical histones in nucleosomes and act as important regulators of chromatin function. H3.3 is a major variant of histone H3 that is remarkably conserved across taxa and is distinguished from canonical H3 by just four key amino acids. Most genomes contain two or more genes expressing H3.3, and complete loss of the protein usually causes sterility or embryonic lethality. Here, we investigate the developmental expression patterns of the five Caenorhabditis elegans H3.3 homologs and identify two previously uncharacterized homologs to be restricted to the germ line. Despite these specific expression patterns, we find that neither loss of individual H3.3 homologs nor the knockout of all five H3.3-coding genes causes sterility or lethality. However, we demonstrate an essential role for the conserved histone chaperone HIRA in the nucleosomal loading of all H3.3 variants. This requirement can be bypassed by mutation of the H3.3-specific residues to those found in H3. While even removal of all H3.3 homologs does not result in lethality, it leads to reduced fertility and viability in response to high-temperature stress. Thus, our results show that H3.3 is nonessential in C. elegans but is critical for ensuring adequate response to stress.

Renal leiomyosarcoma is a rare entity in the world and its understanding is based on reports and various cases; however, the prognosis is bleak for its malignant potential and an average survival of 18 months.

Clinical case

A 54-year-old woman with a clinical picture of 6 months of pain in the right flank and a tomographic image of a bilateral renal lesion underwent right radical nephrectomy and left conservative surgery. The definitive histopathological study reported right primary renal leiomyosarcoma with left metastasis.

Conclusion

Renal leiomyosarcoma is an entity of low incidence and high mortality; however, our case represents the minority of patients with contralateral kidney metastasis reported in the literature.
Stress Whitening in Polyester Melamine Coatings
Authors: Radley Emily , Lowe Chris , Gethin David
Published: April 2018

Stress whitening is a long-standing problem and scientific work has focused on evaluating causes of this in bulk polymer systems. In this paper we focus on this optical defect exhibited by a complex thermosetting polyester melamine coating system used extensively in the pre-coated metal industry. There are several mechanisms proposed for how stress whitening occurs and hence there is uncertainty over the causes in the systems mentioned. The most likely explanation given to date is that a number of proposed micro-mechanisms exist, which one is occurring is entirely dependent on the system being investigated. The work presented shows that the presence of dissimilar particles is the cause of the stress whitening. The proposed mechanism for whitening and its disappearance in this case is a time and temperature dependent change in density, i.e. cracking or voiding, where the cracks are outside the range that scatters light with an increase in temperature.

Published: April 2018

The mechanical strength, mass loss and dynamic elastic modulus of Portland cement concrete incorporating recycled glass powder (GP) as a cement replacement material or crushed glass aggregate (GA) as a fine aggregate replacement material subjected to different cycles of freezing and thawing were investigated. A series of 11 concrete mixing proportions was designed with a constant water/cement ratio of 0·5 including fractions of GP or GA. Tests were conducted on 100 × 100 × 100 mm cubes, 100 × 200 mm cylinders and 100 × 100 × 500 mm prisms. The tests of compressive strength, flexural strength and indirect tension were used to examine the impact of the inclusion of different percentages of glass (GP or GA) on the mechanical properties of concrete cured for 7, 28 and 60 d. Two non-destructive testing approaches (ultrasonic pulse velocity and resonance frequency) were used in the freezing and thawing test. The test results indicated that, compared with conventional concrete, the mechanical strength characteristics of concrete containing GP or GA were more enhanced. The use of GP decreased the deterioration of the concrete under the effect of frost action, whereas the use of GA had an adverse influence on the frost resistance of the concrete.

Authors: Yang Dingtian , Yin Xiaoqing , Zhou Lizhu
Published: April 2018

Seagrass and associated bio-resources are very important for swan’s overwintering in Swan Lake in Rongchengof Shandong Peninsula of China. The seagrass distribution changes, which are usually affected by the regional humanactivities, can indirectly affect swan’s habitat. In this study the satellite remote sensing data in years 1979–2009 togetherwith in-situ observations in recent years were used to examine the seagrass distribution changes in Swan Lake. The bandratio of band 1 to band 2, Lyzenga’s methods and band synthesize of band 1, band 2 and band 3 were used for seagrassretrieval. The band ratio of band 1 to band 2 with ranges greater than 4.5 was used for estimating the seagrass coveragegreater than 50%. Results showed that in years 1979–1990 seagrass coverage greater than 50% occupied more than half ofthe surface area of Swan Lake. In years 2000–2005, the total area with seagrass distributions reduced greatly, only aboutone sixth to one fourth of Swan Lake’s surface area. After 2005, the seagrass area in Swan Lake increased gradually andoccasionally was greater than one third of the total surface area of the Lake. It was shown that human activities such as thedam and fish pond establishment and the awareness of seagrass importance and protected actively result in the seagrassdistributions changes in Swan Lake which decreased first and then increased afterwards.

Published: April 2018

Background: Diabetic foot ulcer is the one among and the most common complication of diabetes mellitus patients. Various studies from over the world for the past 2 decades discuss the important risk factors that decide the prevention and outcome of diabetic foot ulcer. In our prospective study we have discussed the risk factors focused on prevention and treatment of diabetic foot ulcer in a rural tertiary medical care centre.Methods: Totally 940 patients with the clinical diagnosis of diabetic foot ulcer admitted in our hospital surgical department were studied prospectively with their clinical symptoms and signs of diabetic foot ulcer and various evaluations done for the comorbid conditions with the help of other specialty departments. All these risk factors studied in our rural based tertiary medical centre were collected in a designed format were studied and discussed in comparison to the chosen data available in various studies done at various countries.Results: All the 940 patients admitted for diabetic foot ulcer who underwent a methodical evaluation for risk factor showed an elevated HbA1c more than 8 in 720 (77.5%) patients, bony involvement like osteomyelitis in 274 patients (29%) , peripheral vascular disease in 421 (44.9%), neuropathy in 533 patients (56.7%), nephropathy 163 (17.34%), retinopathy in 102 (10.85%) and heart disease in 375 (39.89%).Conclusions: Proper protocols to the prevention and management of foot ulcer in diabetic patients have not reached many health care centres and it is imperative to stress on the related comorbid risk factors which influence the prevention and healing of diabetic foot ulcer. Present study done at a rural tertiary health care centre is mainly focused on the incidence of risk factors which modulates and modify the diabetic foot ulcer prevention and management. This study aims to support the health professionals to identify the risk factors apart from the clinical picture of diabetic foot ulcer that may enhance the efficient management and avoid the unnecessary morbidity and mortality.

EFFECT of IONIC LIQUID CONTENT on MONOLITHIC STRUCTURE of AMINE-MEDIATED SILICA AEROGEL via AMBIENT PRESSURE DRYING
Authors: GİZLİ Nilay , SERT ÇOK Selay , KOÇ Fatoş
Published: April 2018

In
this study, amine-mediated silica aerogels dried under the ambient conditions
in monolithic form were prepared by following sol-gel method.
3-aminopropyltriethoxysilane (APTES) was involved to the synthesis as a silica
co-precursor. Imidazolium based short-chain ionic liquids (ILs) were
incorporated into the silica gel structure to control the gel shrinkage within
the pores, as well as to eliminate the capillary effect during the solvent
evaporation. A production procedure was developed to explore the synergistic
effect of ionic liquids and amine functionalized silica precursor on the
textural and chemical properties of the final silica gels. Surface
modifications of the samples were performed by using
3-Methacryloxypropyltrimethoxysilane (MEMO) to ensure hydrophobic
characteristics. To reveal the chemical and morphological characteristics of
the resultant material, various analyses were conducted.  SEM and FTIR analyses were performed to
investigate the morphological and chemical structure, whereas TGA analysis was
carried out to determine the thermal stability of the silica gels. As a result,
ionic liquid embedded sample was obtained in a monolithic structure with a low
density (0.45 g/cm3) and had a good thermal stability (up to 381 °C). Contact
angle measurement also demonstrated that the desired monolithic sample has
hydrophobic characteristic with a water contact angle value of 113˚.
A ATIVIDADE DO PENSAR E A RELEVÂNCIA DO COMUNICAR NA E PARA A EDUCAÇÃO ESCOLAR: REFLEXÕES À LUZ DE HANNAH ARENDT

Published: April 2018

O presente artigo, de cunho bibliográfico, tem por objetivo tematizar a atividade de pensar e sua relação com o sentido do comunicar no âmbito educacional, a partir das reflexões de Hannah Arendt. Não obstante, uma maneira que temos para estabelecer um vínculo com este mundo é a atividade do pensar, o pensar é o que nos permite buscar significados e sentidos, para qual em outras esferas de nossa existência não é possível, ou não temos espaço e nem tempo. Todavia, para a educação escolar não basta apenas pensar sobre os acontecimentos e experiências que nos rodeiam, é preciso comunicar o que pensamos. É a partir do comunicar que entramos em contato com o pensar de outras pessoas, e é esse momento em que nossos alunos/recém-chegados são desafiados a pensar por conta própria, ou seja, começam a se indagar sobre a sua relação com os acontecimentos, com as demais pessoas e as coisas.

Indicators to Choose a Suitable Marketing Automation Platform
Authors: Berghofer Florian , Hofbauer Günter , Sangl Anita
Published: April 2018

Marketing automation platforms are an efficient tool for the collection, analysis and the processing of customer information. As a consequence, they are a highly relevant aspect of modern marketing, both for the practical and academic discussion. The rising demand implicates a more complex vendor landscape, whereby the comparison and selection of marketing technology are getting increasingly difficult. This article is an analytical and conceptual paper. The research question deals with the identification of indicators regarding the selection of a suitable marketing automation platform. Initially, the increasing necessity of marketing technology is pointed out. A general understanding of marketing automation as relevant subarea of marketing technology will be enabled. For this reason, a definition, relevant features as well as chances and risks are presented on the basis of a critical literature research. A holistic decision model for choosing a marketing automation solution complements the basic information and shows a selection procedure as well as the most essential selection and evaluation indicators. The specific contribution for academic discussion is twofold: Firstly, the key aspects of marketing automation are presented, and its basics are introduced. Secondly, this paper describes a framework that serves as recommendation and orientation for the selection process of marketing automation platforms and marketing technology.
Intimate Partner Violence and Marital Satisfaction: The Mediating Role of Marital Communication and the Moderating Role of Gender
Authors: Yucel Deniz
Published: April 2018

Using data from 501 married individuals living in Northern Cyprus, an understudied context, this study tests the effect of intimate partner violence (specifically, verbal and physical spousal aggression) on marital satisfaction. In particular, this study explores whether marital communication mediates the effects of verbal and physical spousal aggression on marital satisfaction, and whether these effects differ between men and women. Results suggest that respondents who report only verbal spousal aggression or both verbal and physical spousal aggression have significantly lower marital satisfaction than those who report no verbal or physical spousal aggression. Marital communication partially mediates the effect of only verbal spousal aggression, and of both verbal and physical spousal aggression, on marital satisfaction. Furthermore, the results indicate that the effect of only verbal spousal aggression on marital satisfaction is stronger for husbands, while the effect of both verbal and physical spousal aggression on marital satisfaction is stronger for wives.
Police Students’ Perceptions of Intimate Partner Violence in Same-Sex Relationships
Authors: Fröberg Sofi , Strand Susanne
Published: April 2018

The knowledge of same-sex intimate partner violence (IPV) is limited. This study aims to investigate the perception of seriousness of same-sex IPV. A vignette study was undertaken among 248 police students (69% males and 31% females) in Sweden. The vignettes portrayed an intimate partner relationship between two people and were available in four versions with the sex of the offender and victim being alternated. Perceptions of IPV were measured using the Opinions of Domestic Violence Scale (Ahmed et al., 2013). The results showed that regardless of gender, IPV was considered serious; however, same-sex IPV was perceived as less serious than victimization of a heterosexual female but more serious than victimization of a heterosexual male. Police interventions were found to be less needed for same-sex victims than for heterosexual female victims.
African Theology in the 21st Century: Mapping Out Critical Priorities
Authors: Waweru Humphrey Mwangi
Published: April 2018

There is a dialogue taking place in the area of African Theology; “do we call it African Christian theology or African Theology and how it relates to the African culture”? Depending on where one sits, any name will carry the day as long as it fulfills the academic desire intended. What is important is the dialogue that is taking place between the Bible and the African culture. Here, we shall take the name “African Theology” as the norm. It is evident in almost all ways that from a walk which is based on the mapping of African theology or from the wide variety of current understandings of its nature and task, there are several priorities in African Theology. A number of theologians today argue that the priorities of African theology are many. These include providing a clear and comprehensive dialogue between African culture and the Bible in relation to the African faith. They argue that the Bible has also been translated into local languages in order to enable the African cultures to become intelligible in the way they relate to the scriptures. On the other hand, others have prioritized the definition of African Theology so that they can deal with it from their perspective of African Traditional Religions. Also, others want to prioritize African Theology as a reflection of the praxis of Christian faith within a relatively deprived community. Therefore, this article seeks to briefly provide some priorities in African Theology, such as liberation, reconstruction, and poverty reduction theologies. In this study, we will proceed to explore the need for a definition of African Theology, how it relates to African Christian faith, and the challenges posed by African Theology to the Christian faith. We will conclude with the general guidelines on formulating the priorities of African theology.
Extension Du Reseau De Distribution D’eau Potable Dans Le District d’Abidjan
Authors: N’kongon Yéradé Jeanne
Published: April 2018

The aim of the present study was to find a mechanism for funding the extension of the drinking water network to the poor neighbourhoods of the District of Abidjan in order to bring drinking water close to the disadvantaged populations. To this end, microeconomic data collected from one thousand households, spread over the entire territory of the Abidjan District, were used. A statistical analysis enabled the study to describe poor population’s access to drinking water and to highlight the inadequacies in the distribution of such a universal service. The use of type-II tobit model (the Heckman method) in analysing the data also enabled the study to identify the main explanatory factors for the district’s population’s willingness to pay (WTP) for the extension of the drinking water distribution network to their poor neighbourhoods. And average WTP for water extension in Abidjan is 140350 CFA francs per household and per year.
Analyse De L'efficacité Technique Des Exploitations Agricoles Familiales À Maurice

Published: April 2018

This study was undertaken to determine the technical efficiency of family farms and to identify the factors which determine their productivity. All in all, 200 farmers were randomly selected and interviewed using a structured questionnaire to obtain data on agricultural production and input use during 2014. The Data Envelopment Analysis (DEA) technique was used to determine the levels of technical efficiency of such enterprises. Besides, a Tobit regression model was applied to identify the factors influencing the technical efficiency of farmers in agricultural production. The average technical efficiency under the variable scale yield is 0.726. This implies that it is possible to increase agricultural production by 27.4% compared to the current level of inputs. The results show that 46.5% of the sample is technically efficient under variable scale yield. The results showed that productivity is significantly influenced by the sex of the farmer, the area of cultivated land and the wage of labor. It is therefore recommended to undertake a policy to improve the formal education of producers, to build capacity of their organizations and facilitate to them access to land and inputs.

Pigeon pea (Cajanus cajan (L.) Millsp.) is an important drought tolerant legume cultivated in the semi-arid regions, mainly in Sub-Saharan Africa. Despites its important potential, the crop is neglected and underutilized in many countries including Benin. In order to develop efficient in-situ strategies conservation, a study was conducted to quantify pigeon pea landrace diversity and access its spatial distribution and traditional management by local communities in southern Benin. Therefore, an ethnobotanical survey was conducted in 20 producing villages in southern Benin. Altogether, 26 farmernamed landraces further grouped into five categories were recorded with the number of landraces really cultivated per farmer comparably lower than that listed. Besides, two landraces’ categories were found to be common in the study area while two other were found highly threatened. Diverse parameters such as varietal richness, Shannon-Weaver Diversity Index, Simpson index and Pielou’s evenness were used to quantify pigeon pea diversity that appeared to be unequally distributed through the different agro-ecologies and villages surveyed. The study confirmed the absence of correlations between farmers’ gender and landrace diversity which was nonetheless found to be significantly shaped by the ethnic group and the field size exploited by farmers (P < 0.05). In diversity management, five preference criteria with variable importance across the ethnic groups were used by farmers of which cooking time and market value appeared to be the most important. Exhaustive germplasm collections, morphological/molecular characterizations of these landraces are required for efficient conservation of this important but neglected crop genetic resource in Benin.

Background: In malaria endemic areas, pregnant women are constantly at risk of repeated malaria infestation which if left untreated, poses a significant threat to the health and survival of the mother and her baby. Objective: This study determined the prevalence and risk factors for placental malaria parasitaemia among parturients at the Federal Medical Centre, Yenagoa, Nigeria. Methodology: A prospective cross-sectional analytical study of 205 parturients recruited consecutively at presentation for delivery. An interviewer-administered questionnaire was used to collect data. After delivery, placental blood was collected for microscopy to detect malaria parasites. Data was analysed using SPSS version 22. Results: The prevalence of placental malaria parasitaemia was 13.7%. Maternal age <25 years (P<0.001), low educational status (P = 0.03), low parity (P = 0.03), unbooked status (P < 0.001) and non-use of intermittent preventive treatment (P <0.001) were significantly associated with placental malaria parasitaemia. Receiving three or more doses of sulphadoxine-pyrimethamine for intermittent preventive treatment of malaria in pregnancy was by far, more protective for placental malaria than receiving 2 doses (odds ratio = 0.25). Plasmodium falciparum was the only parasite species detected. Conclusion: Malaria still ravages our obstetric population and the significant contributors include low maternal age, low educational status, low parity, unbooked status and non-use of intermittent preventive treatment in pregnancy. Women should be encouraged to utilize antenatal care. There should be a prompt adoption of the recent WHO recommendations regarding malaria prophylaxis in pregnancy in all obstetric units and the medication should be given as Directly Observed Therapy.

The use of Tropical Rainfall Measuring Mission (TRMM) data is an option for counteracting challenge of the lack of ground based observations, particularly in Kayanga/Gêba. This paper undertakes validation of monthly TRMM rainfall estimates before using it to understand the spatial and temporal variability in the Basin. This validation based on application of statistical study, made it possible to obtain interesting results with correlation coefficients varying from 0.92 to 0.96 and Nash indices close to 1. The analysis of the seasonal rainfall pattern shows consistence with ground based observations. The study of the annual cycle reveals that their interannual variability is similar to that of ground based observations. Finally, the interpolation of average monthly rainfall in the basin highlights the NorthSouth rainfall gradient, which shows that the South is wetter than the North, with differences more pronounced in August and September.

The cultivated rubber clones are sensitive to latex harvesting regimes according to their laticiferous metabolism. Thus, in order to determine the best latex harvesting systems of clones with low or slow metabolism, six latex harvesting technologies are applied to them in a bulk statistical device from Fisher to four rehearsals. The rubber is tapped in downward half spiral stimulated or not for nine years after the opening of the tapping panel. The agronomic parameters (production, vegetative growth), the tapping panel dryness and those of the latex micro diagnosis were evaluated. The results indicate that these clones independently of the latex harvesting system have good rubber productivity (2310 kg.ha -1 .y-1 ) with good radial vegetative growth (2.9 cm.y -1 ). Their trees show a well-balanced physiological profile and an acceptable sensitivity to the tapping panel dryness (4.9%). However, the physiological index, the bark consumption and the sensitivity to the tapping panel dryness lead to retain the latex harvesting technologies "S/2 d3 6d/7 Pa1(1) ET2.5% 4/y, S/2 d4 6d/7 Pa1(1) ET2.5% 4/y and S/2 d4 6d/7 Pa1(1) ET2.5% 8/y” for the best. This index, favorably influencing the choice of technologies adapted to clones with active metabolism, contributes to the modern and efficient management of a rubber plantation.

Published: April 2018

The current study is intended to explore the prevalence of aggression level of students with autism based on gender, age, and intellectual state. The study sample is composed of parents for (108) of children with autism. These students are aged 5-16 years old who have been attending the autism centers in the State of Kuwait. The current study has utilized a three-dimensional aggression scale, which includes aggression toward others, aggression toward self, and aggression toward things. The result of the study reveals that among the participant's aggression toward others has been ranked the highest on subscale, followed by aggression toward self, and lastly aggression toward things. The study further exposed that the most significant aspects of aggression were explicit obstinacy and refusal when asking the participant to perform an action, the act of pinching others in a state of anger, kicking others without any legit or obvious reason, throwing himself on the floor, and hitting himself with his hand or any other part of his body. In addition, the results of the study suggests that there are a statistically significant differences based on gender in aggression toward things, which is in favour of female. No statistically significant difference has been observed based on gender on aggression toward others. As per the total score of aggression scale, there is no statistically significant difference found based on age or intellectual state of all aggression subscales.

Arapça ve İngilizce yayınlarıyla
Ortadoğu’da ve küresel düzeyde alternatif bir haber kaynağı haline gelen El
Cezire yayıncılık politikaları sebebiyle bölgesel bir krizin parçası haline
gelmiştir. 2017 Haziran ayında Körfez ülkeleri ve Mısır ile Katar arasında
başlayan kriz halen çözüme kavuşturulmuş değildir. Katar’a uygulanan yaptırımların
kaldırılması karşılığında sunulan taleplerin arasında El Cezire ve ona bağlı
tüm kuruluşların kapatılmasının istenmesi medya tarihinde eşine az rastlanır
bir sansür örneği olarak karşımıza çıkmıştır. Katar Devleti’nin yerine
getirmeyi reddettiği bu talep bundan sonraki süreçte kamu yayıncılığının
uluslararası sorunların bir parçası olabileceği ihtimalini göstermektedir. Bu
çalışmada Katar krizi bağlamında El Cezire’nin diplomatik bir krizin parçası
olduğu süreç örnek olay olarak incelenmiştir. El Cezire ve kamu yayıncılığı
üzerine oluşan literatürden ve sürece ilişkin haberlerden yola çıkarak
oluşturulan araştırma sorularına cevap aranmıştır. El Cezire’nin yayın
politikalarına getirilen eleştirilerin kanalın kapatılması talebine gerekçe
olamayacağı ve böyle bir talebin küresel düzeyde özgür medya ekolojisine zarar
vereceği sonucuna varılmıştır. Çalışmanın otoriter rejimlerle idare edilen
Ortadoğu ve Arap ülkelerinde Katar Krizi’nin ardından objektif yayıncılığın
geleceği ve mevcut kamu yayıncılığı modelleri üzerine bir tartışma alanı
açılacağı umulmaktadır.
