The Impact Of Political Instability Driven By The Tunisian Revolution On Stock Market Volatility: Evidence From Sectorial Indices
Authors: Zaiane Salma 
Published: March 2018

The aim of this paper is to study the impact of political uncertainty, driven by the Tunisian Revolution, on return and volatility of major sectorial stock indices in the Tunisian Stock Exchange. We specifically use EGARCH (1.1) model from 01/12/2010 to 31/08/2016. This model is applied to the daily returns relevant to ten sectorial stock indices and to the Tunisian benchmark index (TUNINDEX). To test the impact of political news on returns and volatility, we divided them into two groups (good and bad news).
Our results show that both of good and bad news have increased the volatility of major selected indices, including the TUNINDEX. However, the return of all indices are not affected by the political news. We then examined the impact of terrorism on the behavior of indices return and volatility. Results show that the Tunisian market responds significantly to terrorist acts. Hence, the return declines and the volatility increase the day of terrorist attacks. Furthermore, results confirm that bad news have stronger effect on the volatility than good news, which reveal the asymmetric effect of volatility.

Published: March 2018

This study aim is to know the effect of silica composition on the absorption of electromagnetic waves in the composite of unsaturated polyester resins (UPR)/silica. Silica raw materials have been synthesized from the results of rice husk ash extraction. The results of the analysis phase and elementary respective using X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) show that the extraction of silica has an amorphous phase with a high purity. This silica powders are filler material acts as an electromagnetic waves absorber material and combined with the UPR as a matrix to form a composite. Silica powder varied with several compositions in this composite. The observation of scanning electron microscope (SEM) shows that the silica particles have been distributed evenly in the UPR matrix. Meanwhile the results of testing the absorption of electromagnetic waves at frequency range of 8 GHz - 12 GHz using a vector network analyzer (VNA) show that the addition of silica composition have significant effect on the absorption of electromagnetic waves. The more the silica content in the UPR matrix causes the absorption of electromagnetic waves more increasing. It was concluded that the presence of silica can improve the absorption performance of electromagnetic waves in composite UPR/silica.

This study was aimed to evaluate the utilization of jack bean meal as a substitution of soybean meal in the diets and the effect on broiler performance. A total number of two hundred Lohmann MB 202 Platinum broiler chickens were kept in five weeks rearing period, consisted of three weeks of starter phase (0-3 weeks) and two weeks of finisher phase (3-5 weeks). This study used a completely randomized design with four treatments and five replicates. The dietary treatments were: JB0-0 (control ration: basal diet without jack bean meal substitution in starter and in finisher phase), JB50-0 (basal diet with jack bean meal substitution in starter phase only), JB50-50 (basal diet with jack bean meal substitution in starter and in finisher phase), JB0-50 (basal diet with jack bean meal substitution in the finisher phase only). The data obtained were statistically analyzed using analysis of variance and followed with Duncan's multiple-range test for the data with significant difference. The variables measured were: growth performance, carcase yield, visceral organ weight and immune organ. Results showed that the dietary treatment had no effect on performance, carcass yield and commercial cut, visceral organ or immune organs of 35 days old broiler chickens, except for the thymus (P<0.05). It can be concluded that as a source of protein, soybean meal can be replaced by jack bean meal up to 50%. Jack bean meal can be given either in starter phase only, in finisher phase only, or in both starter and in finisher phase.

The method of analysis using approaches of feasibility cattle business, supply chain channels of cattle and beef commodities, and cattle supply chain management at farmers’ level. Analysis results show that small-scale cattle fattening business on cash costs was still profitable, but its profit was lower or incurring loss if based on the total costs. Medium and large business scales were profitable and depending on the race types of cattle business. Supply channels were diverse and quite long controlled by middlemen, slaughters, and inter-regional traders/distributors. Supply chain management performance of cattle commodity was relatively well structured with low to moderate market integration. To improve the supply chain management performance, it is necessary to implement a horizontally-integrated business. In addition, it is urgent to involve small and medium-large business involvement, as well as partial vertical integration.</p><p> </p><p>Abstrak</p><p>Produk daging sapi permintaannya terus meningkat dan belum mampu dipenuhi dari produksi domestik. Pemerintah memutuskan bahwa pemenuhan kebutuhan daging sapi menjadi salah satu prioritas utama yang tercantum dalam Renstra Kementerian Pertanian 2015-2019. Penelitian ini bertujuan untuk mengkaji kelayakan usaha ternak sapi pada berbagai skala usaha, saluran rantai pasok, dan kinerja manajemen rantai pasok komoditas ternak sapi dan daging sapi. Metode analisis menggunakan analisis kelayakan usaha ternak sapi, saluran rantai pasok komoditas ternak dan daging sapi, serta manajemen rantai pasok ternak sapi di tingkat peternak. Hasil kajian menunjukkan bahwa usaha penggemukan sapi skala kecil atas biaya tunai masih menguntungkan, namun jika berdasarkan atas biaya total keuntungannya menjadi turun bahkan merugi. Pada usaha skala menengah dan besar memberikan keuntungan yang bervariasi dari moderat hingga tinggi tergantung pada ras sapi yang diusahakan. Saluran rantai pasok sangat beragam dan cukup panjang dengan peran utama pedagang pengumpul antar desa/kecamatan dan pedagang pemotong/pejagal, dan pedagang antar daerah/distributor. Kinerja manajemen rantai pasok komoditas ternak sapi menunjukkan bahwa tipe struktur pengelolaan rantai pasok ternak dan daging sapi tergolong kategori “keterkaitan pasar” dengan tingkat kinerja pada level rendah hingga moderat. Implikasi kebijakan untuk meningkatkan kinerja manajemen rantai pasok dapat dilakukan melalui usaha yang terintegrasi secara horizontal, meningkatkan kinerja penerapan manajemen rantai pasok dengan melibatkan usaha skala kecil dan menengah/besar, dan meningkatkan integrasi vertikal secara parsial ke arah lebih holistik. </p>

Citronellal is the main component in kaffir lime oil that has great potential utilization in industrial and pharmaceutical field. Citronellal purification using conventional method, such as destillation, requires lots of solven, special equipment and lots of time. Alternatively, purification method using base catalyst NaHSO<sub>3</sub> and Na<sub>2</sub>SO<sub>3</sub> as reagent could be more simple. This research aimed to evaluate the effect of the base catalyst used for hydrolysis in the purification process of citronella using salt reaction with NaHSO<sub>3</sub> and Na<sub>2</sub>SO<sub>3</sub> reagents. The experiments was conducted in the Laboratory of Organic Chemistry, Brawijaya University, Malang, from August 2015 to February 2016. The research was arranged a randomized block design with factorial treatments. The first treatments was two types of reagents, NaHSO<sub>3</sub> and Na<sub>2</sub>SO<sub>3</sub>. The second one was the variations of base catalyst used for hydrolyzing NaHCO<sub>3</sub>, Na<sub>2</sub>CO<sub>3</sub> and NaOH. The purity of hydrolyzed citronellal was measured by gas chromatography-mass spectrometry. The highest purity of citronella 89,29 % was obtained with the used of Na<sub>2</sub>SO<sub>3 </sub>reagent at the mole ratio 1:2, hydrolyzed by Na<sub>2</sub>CO<sub>3</sub> (pH 10.98). Thus the method, can be recommended in purifying citronellal from kaffir lime oil.

<em>Brown planthopper is still a major problem in rice. Control using botanical insecticides is considered less effective, since its persistence in rice plantation is short. Research on the persistence of botanical insecticide residues of pyrethrum and neem in rice has been conducted in green house of Entomology, Indonesian Spices and Medicinal Crops Research Institute, Bogor from January to December 2016. The research was aimed to determine the persistence of botanical insecticide residue on rice by testing it to brown planthopper mortality. The study was arranged in complete randomized design with six treatments and four replications. The treatment consisted of two pyrethrum formulas (EC); two neem formulas (EC); positive controls of synthetic insecticides (a.i. carbosulfan) and negative control (water). The method used was Leaf Residue Method, by spraying the formula into one month-old rice plants, then 10 brown planthopper nymphs of forth instar were introduced into each plant in the first, second, third and fourth day after spraying. The planthopper mortality was observed in the first, third, sixth, 24th and 48th hours after introduction. The residuals of all insecticides tested were still affecting the mortality of brown planthopper until the fourth day after spraying, although the effectiveness</em> <em>decreased by the time. The average mortality on the first day introduction after spraying ranged between 53-73 % and in the fourth day after spraying was 18-25 %.</em>
A Comparison of Nursing Maths Support Approaches
Authors: Little John 
Published: March 2018

This article compares interventions for improvement of students’ numeracy and drug calculations skills respectively; numeracy test / re-test with maths support versus a numeracy workshop and a calculations drop-in. In the first intervention supported students increased their mean score from 19 out of 40 to 30 out of 40 and their peers increased from 27 out of 40 to 30 out of 40, both statistically significant increases. In the second intervention the highest scoring group of students made use of both the workshop and the drop-in. Whilst there was no statistically significant difference in mean scores across the four identified groups of students there were no low scoring outliers amongst the students who made use of the support offered. Although there is stronger evidence for the first intervention having impact, the second intervention is more aligned to drug calculations skills development. However, the latter would need a larger scale sample to confirm efficacy.

Published: March 2018

Los sentidos humanos tienen una importante capacidad para detectar patrones espaciales, pero sus limitaciones son enormes, como lo han demostrado la psicología cognitiva y la Gestalt desde hace mucho tiempo. Por tanto, se requieren instrumentos más precisos y confiables para identificar patrones y actuar en consecuencia. El análisis espacial ofrece diversas alternativas para identificar patrones territoriales estimando su significancia estadística, con lo que se minimiza la posibilidad de percibir patrones ilusorios. Este trabajo utiliza desarrollos de punta en materia conceptual, metodológica yde tecnología para: a) Identificar con estadística espacial los clusters de inmuebles dañados por el sismo del 19S-2017 en la CDMX. La estrategia se basa en una secuencia de zooms a diversas escalas geográficas: desde la escala global para toda la CDMX, pasando por las escalas de delegación, colonia y manzanas, hasta llegar a la escala mínima de inmueble; b) localizar Unidades Móviles de Emergencia mediante modelos delocalización-asignación, y c) comparar los patrones espaciales de inmuebles colapsados y dañados por los grandes sismos de 1985 y 2017. Los resultados de este trabajo podrán orientar los esfuerzos de reconstrucción, atención e investigación hacia zonas prioritarias espacial y estadísticamente significativas.
