The relationship between fees and performance of domestic equity funds in Thailand
Authors:   , Suphapitakpaiboon Thapanee 
Published: June 2023

This study inclusively examines the relationship between fund fees and performance of open-end domestic equity funds in Thailand from 2010 to 2019 to analyze the domestic-equity fund market in 2 main dimensions: the market competitive and conflict-of-interest between the duties of asset management companies (AMCs) to their parent bank and to unitholders through fund fee channel. The study investigates the relationship of (1) fund fees, (2) fund fees set by bank subsidiaries, and (3) fund fees set by large-bank subsidiaries with its performance in term of both returns over benchmark and Jensen’s alpha.

Based on the results, investors paid higher fees to AMCs without compensating the fees with superior performance from investment in Thai domestic-equity funds on average. These also implies the domestic equity funds market is not able to be concluded that the market is highly competitive. For funds managed by bank subsidiaries, the result reports that there is statistically significant in the additional negative impact from the fees set by bank-subsidiaries on the fund performance. Thus, the fees set by bank-subsidiaries do matter as it could higher deteriorate the fund performance. One of underlying concept to explain this is because of bank conglomerate structure in mutual fund market, there is possible that AMCs may involve in the activities such as increase in fund fees collected from unitholders that was beneficial to parent bank in term of increase in its revenue rather than maximizing the interests or fund returns to unitholders. Moreover, to inclusively study in conflict-of-interest issue through fund fee channel, the result significantly shows that investors would significantly pay higher fees especially to non-large bank subsidiaries and not receive superior performance.
Determining the tracking error and value-at-risk of an active portfolio when combined with a passive portfolio with value-at-risk constraint

Published: June 2023

When an asset manager manages a portfolio, he usually imposes a TE or a VaR limit on his portfolio to control portfolio risks. However, a portfolio may be divided into different portions. In our research, we consider a portfolio that consists of an active portion and a passive portion. Having a VaR budget of an entire portfolio, we propose methods to determine TE and VaR limit on the active portfolio and illustrate them by using real data. In the empirical part, some problems can occur when we relax certain theoretical assumptions such as (1) stocks in an investment universe can be different from stocks in a benchmark (2) there is a restriction on short-selling. Moreover, risk measures derived from the analysis part are "ex-ante," but calculation methods for monitoring are "ex-post." Therefore, we need to consider these limitations when using the proposed limit on TE and VaR of an active portfolio in real life.
Double bottom pattern recognition for trading strategy
Authors:   , Nuntanart Chusana 
Published: June 2023

We utilize the Double bottom pattern, which is a common and the most easily recognized reversal pattern in the technical analysis approach, to seek the existence of abnormal returns from 1 Jan 2009 to 31 Dec 2019. The general event study methodology was used to statistically test for the existence of abnormal returns from 611 stocks in SET. We concluded that there was an existence of abnormal return from trading with the Double bottom pattern strategy. This led to the conclusion that the Thai stock market might be not as informationally efficient as academics have conjectured.
كيف كانت اتجاهات طلبة كلية التربية بجامعة صنعاء نحو تعليم المرأة في المجتمع اليمني في مطلع التسعينات
Authors: الفقيه أ.د وهيبة غالب فارع 
Published: June 2023

للمرأة اليمنية مكانة تاريخية واجتماعية بالغة الأهمية بحكم الخصوصية التاريخية لليمن وبحكم الطبيعة الاقتصادية الزراعية، ولكن الظروف السياسية التي مر بها المجتمع اليمني منذ مطلع القرن العشرين ساهمت في بقاء أجيال كاملة من الأميين والأميات لا يزال تأثيرها قائما على مكانة المرأة وأدوارها الاجتماعية الحديثة.
وإذا كان من الصعب الحديث عن ذلك الماضي فانه ليس من السهل أيضاً وصف تدافع المواطنين نحو التعليم وتباريهم في تحويل أجزاء من منازلهم الخاصة إلي مدارس وقاعات درس عامة عندما أصبح التعليم حقا دستوريا للجميع بعد ثورة 1962 وقد أسهمت المرأة ماديا وللجميع في بناء المدارس في قرى ومدن البلاد عندما أتيحت لها فرصة المشاركة لتي لم تفرق بين رجل وامرأة .
ويفضل تلك الجهود استطاع المجتمع تجاوز المسافات المظلمة من حياته والاتجاه نحو التغيير خلال حقبة زمنية قصيرة قياسا بما كان قائما ولم تكن المدرسة سوى إحدى الوسائل التي مكنته من ذلك والتي كان للمرأة كما يبدو دور هام في إيجادهامما زاد من رصيد عطائها لمجتمعها الذي لم يكن يملك الإمكانيات المادية الكافية للتصور، لكنه كان يملك الإرادة لفعل حدث عظيم وهو التحول نحو المعرفة فأصبح التحاق الإناث بالمدارس ضرورة وواجبا وطنيا اقتضتها ظروف المرحلة الجديدة المعبرة عن رغبة قوية في التغيير [1] ومع كل ما حصلت عليه المرأة من حقوق دستورية يدور التساؤل في الوقت الحاضر حول استمرار المرأة في تأدية مثل هذا الدور أولا والفائدة التي جنتها هي وبناتها من نشر التعليم ثانيا بعد وصوله إلي مختلف المناطق وفي ظل ظروف اجتماعية.

ابن خلدون علم يدوي اسمه في جنبات التاريخ الوسيط والحديث، كتب عنه، وعن أعماله وتراثه الفكري الكثير، وحظيت مقدمته بشهرة واسعة، فقد تداولتها الأقلام بالبحث والدراسة والتحليل، وعاد إليها أرباب الفكر السياسي والعلوم الاجتماعية والبحثة. تعامل معها أهل السياسة وأهل الاجتماع وأهل الاقتصاد وأهل الفلسفة وأهل الكلام. وأهل التاريخ، وأهل التربية الخلقية والنفسية، وأهل العلوم الطبيعية، وعلوم الكيمياء والفلك، وعكف على قراءتها طلاب العلم.. وتشعب الجميع في فهمها، ووجد كل من هؤلاء وأولئك فيها لقيته، ونال كل مدع وصلا بها شيئاً من مبتغاة.

وهذه قراءة مقتضبة في فكر ابن خلدون السياسي، لم تستوف فكره، ويشفع لقصورها أنها لم تكن بحثاً مستقلاً به ومن ثم لم يطل بها الاسترواح في أفياء مقدمته الرائدة، التي طالما سكنت إليها القلوب والعقول وتزاحمت عندها ..الأقلام... ويا لها من دوحة عظيمة، ممتدة الفروع والأفنان ندية الظلال كثيرة الأفياء. خضرة نضرة، تورق بالحكمة، وتفرح بأريج الفكر، وعبير المعرفة ... كيف لا ؟ وقد تعهدها صاحبها العبقري الفذ ابن خلدون بنور الرسالة الخالدة وأغناها بتجاربه العلمية، وسقاها من ينابيع التاريخ، وأفكار العلماء والفلاسفة والحكماء، وأهل الفقه والحديث والرأي المتقدمين منهم والمعاصرين له... فجاءت - على حد قوله- مذهباً عجبياً، وطريقة مبتدعة، وأسلوباً نبه بها عين القريحة من سنة الغفلة، والنوم مع كل ما تقدم من إشارات الى موسوعته الفكرية والاجتماعية والسياسية والاقتصادية والعلمية، ومع ما قاله من مطموسة هذه الموسومة بأنه "مستحث الصناعة، غريب الازمة، غزير الساقية اعثر عليه البحث، وأدى إليه الفرص" فإنه لم يدع الكمال لا ما قدم القد قال ورتوا تعلمه فلنناظر المحقق إصلاحه، ولي الفضل، لأني اتهمت له السبيل، وأوضحت له الطريق ".

هدفت هذه الدراسة إلى التعرف على واقع الحوكمة و مدى التزام الشركات المساهمة الجزائرية بمبادئ الحوكمة المنصوص عليها من طرف منظمة التعاون الاقتصادي والتنمية OECD ،التأكيد على أهمية مبادئ حوكمة الشركات في دعم الأداء الاقتصادي الجزائري، على اعتبار أنها تعد بمثابة نقطة مرجعية بالإمكان استخدامها من قبل صانعي السياسة في غمار إعدادهم للأطر القانونية والتنظيمية لأساليب حوكمة الشركات،
ولتحقيق هدف هذه الدراسة قمنا بتصميم استبيان موجه الى كل من المهنيين ،أعضاء مجالس الإدارة ، محافظي الحسابات، المساهمين و المستثمرين ، أعوان البنوك ، إدارة الضرائب و العمال ، وقد تم اختيار عينة الدراسة لمختلف الفئات بطريقة عشوائية بحيث بلغ حجمها (80) ، و تم توزيع الاستبانات على جميع أفراد العينة عن طريق المقابلة المباشرة لأفراد العينة ، و بعد عملية الفرز و التبويب تقرر الإبقاء على (50) استبانه من المجموع الكلي، لتمثل عينة الدراسة و ذلك بعد إقصاء باقي الاستبانات و المقدرة ب (30)، بعضها استبعدت للنقص أو لتضارب الإجابات. لقد تم استخدام أسلوب التحليل الاحصائي الوصفي و الإستدلالي، لوصف وتحليل بيانات الدراسة، وإختبار فرضياتها
خلصت نتائج تحليل الدراسة إلى أن الشركات المساهمة في الجزائر لازالت تعاني من عجز كبير في تطبيق مبادئ الحوكمة ، و أن هذا راجع بالدرجة الأولى إلى تأخر الجزائر في تبني هذا المفهوم إضافة إلى قله وعى المهنيين و استيعابهم لمبادئ حوكمة الشركات و ضرورة احترامها.

Índice de Regularização Ambiental Hídrico de empreendimentos fiscalizados – IRA HÍDRICO – como ferramenta para planejamento estratégico e formulação de políticas ambientais regionalizadas em Minas Gerais
Authors: Lasmar Breno Esteves , Friche Guilherme Passos , Costa Michele Mamedes , Bonaccorsi Mauro Manzali , Oliveira Iara Andrade 
Published: June 2023

O Índice de Regularização Ambiental Hídrico de empreendimentos fiscalizados foi criado tendo por base infrações ambientais caracterizadas por uso irregular de recursos hídricos no período de 2016 a 2019. Trata-se de uma ferramenta que contribui para definições de políticas públicas ambientais regionalizadas, planejamento e estratégia de gestão e fiscalização do uso dos recursos hídricos em Minas Gerais. Dentre os resultados alcançados, destaca-se, pela importância: (1) ausência de cadastro de uso insignificante de recursos hídricos, a extração de água subterrânea, e a captação ou derivação de água superficial sem outorga, que guardam estreita relação com empreendimentos agrícolas, correspondentes às 3 modalidades de infração mais recorrentes no período entre 2016 e 2019; (2) o tempo médio de resposta na busca pela regularização após a fiscalização em cada uma das Superintendências Regionais de Meio Ambiente (Suprams), variando entre 168 e 357 dias; (3) empreendimentos de pessoas físicas, vinculados ao maior número de infrações ambientais por uso irregular de recursos hídricos, buscam a regularização em tempo menor que os empreendimentos de pessoas jurídicas; (4) pessoas jurídicas de direito público, embora relacionadas a um reduzido quantitativo de registros de infrações, são as que menos buscam regularização de seus empreendimentos, e o fazem em um tempo médio maior.

The Water Environmental Regularization Index for inspected enterprises was designed based on environmental infractions characterized by irregular use of water resources in the period from 2016 to 2019. It is a tool that contributes to defining regionalized environmental public policies, planning and strategy of management as wells as inspection of the use of water resources in the state of Minas Gerais. Among the results achieved, the following stand out for their importance: (1) absence of a record on uses of water considered insignificant , the extraction of underground water, and surface water abstraction without water permit, which are closely related to agricultural enterprises, corresponding to the three most recurrent types of infraction in the period between 2016 and 2019; (2) the average response time in the search for regularization after inspection in each of the Regional Environmental Offices, varying between 168 and 357 days; (3) enterprises of individuals, linked to a greater number of environmental infractions due to irregular use of water resources seek regularization in less time than enterprises of legal entities; (4) public legal entities, although related to a reduced number of infraction notices, are the ones that least seek regularization of their enterprises, and do so in a longer average time.
Tendências temporais e espaciais da qualidade das ´´águas superficiais da bacia hidrográfica do rio Piranga, Minas Gerais
Authors: Pereira Alex Cardoso , Rezende Ana Augusta Passos , Braga Gustavo Bastos , Ramos Oda Tatiana Yuri 
Published: June 2023

Este estudo apresenta uma análise da tendência temporal e espacial da qualidade das águas superficiais da bacia hidrográfica do rio Piranga, sub-bacia hidrográfica do rio Doce, em Minas Gerais, Brasil. Foram aplicados testes estatísticos, multivariados e não paramétricos para avaliar 19 parâmetros de qualidade de 7 estações da rede de monitoramento do IGAM/ANA, obtidos no período de 2008 a 2018. Os resultados das análises de correlação de Spearman e de tendência Mann-Kendall sugeriram que 73,68% dos parâmetros apresentam valores com tendências de redução ou aumento, com maiores alterações associadas a cloreto total, condutividade elétrica in loco, ferro, nitrato e pH. A Análise de Cluster definiu três grandes grupos de estações de monitoramento, agrupadas segundo a região dentro da bacia hidrográfica, correspondentes à parte alta, média e baixa. No entanto, ao longo de toda a bacia hidrográfica, foi observado a degradação da qualidade da água durante o período avaliado, principalmente relacionada ao lançamento de esgotos domésticos e escoamento superficial de áreas agrícolas. O fato de o IQA não apresentar tendência temporal merece atenção dos órgãos governamentais para ações de recuperação da qualidade das águas superficiais nos cursos d’água da região.

Abstract
This study presents an analysis of the temporal and spatial trend of surface water quality in the Piranga River watershed, a sub-basin of the Doce River, in Minas Gerais, Brazil. Statistical, multivariate and non-parametric tests were applied to assess 19 quality parameters of 7 stations in the IGAM/ANA monitoring network, obtained from 2008 to 2018. The results of Spearman correlation and Mann-Kendall trend analyzis suggested that 73.68% of the parameters show values with varying trends, with greater changes associated with total chloride, in loco electrical conductivity, iron, nitrate and pH. The analyzis of hierarchical clusters defined three large groups of monitoring stations, grouped according to the region within the hydrographic basin, corresponding to the upper, middle and lower parts. However, throughout the entire hydrographic basin, degradation of water quality was observed during the evaluated period, mainly related to the release of domestic sewage and surface runoff from agricultural areas. Thefact that the WQI –Water quality Index –of 4 of the 7 stations present a temporal trend of stabilization, in values considered as regular, deserves attention from the social actors of the hydrographic basin for actions to recover the quality of surface water in the watercourses of the region, especially in the region from the source and mouth of the Piranga river.

Published: June 2023

As veredas são ecossistemas típicos do Cerrado central do Brasil, caracterizados por ocorrer em solos hidromórficos, com afloramento do lençol freático e buritis como símbolo arbóreo. Essa fitofisionomia contribui para a manutenção de rios e são áreas de preservação permanente. O objetivo deste estudo foi avaliar a qualidade da água em cinco veredas na região de Uberlândia/MG, sendo três rurais e duas urbanas. O monitoramento de parâmetros físico-químicos e metais foram realizados por doze meses, abrangendo épocas chuvosa e de seca. Análises por componentes principais mostraram que a conservação da vegetação nas veredas pode contribuir para a qualidade da água. Os atributos químicos revelaram grandes diferenças na qualidade da água entre as áreas alagadas. Sendo que a área com mais interferências antrópicas foi uma das veredas urbanas. Este estudo também mostrou que as áreas com mais intervenções, exercem maior pressão na qualidade de água do que nos ambientes preservados.

Abstract
The palm swamps (vereda) are ecosystems in Brazilian savanna (Cerrado) characterized by the occurrence of hydromorphic soils, where there are water table outcrops and the Mauritiaflexuosais the arboreal symbol. This phyto physiognomy contributes to the maintenance of rivers and those zones are considered permanent preservation areas. The objective of this study was to evaluate water quality in five palm swamps near the city of Uberlandia/MG, three in rural and two in urban areas. It was carried out the analysis of physical-chemical parameters and metallic elements over twelve months covering rainy and dry seasons. The analysis ofthemost relevant components also showed a decrease in water quality due to land use and occupation in the palm swampsand their surrounding areas, as evidenced by differences in the physicochemical parameters of analyzed wetlands. The area with the most anthropic interference was one of the urban located palm swamp. This study also showed that the areas with more interventions exert grater pressure on water quality than in preserved environments.

Abstract
The present study was carried out in the Itapocu River watershed, Santa Catarina -Brazil. The main purpose of this article was the spatiotemporal analysis of the water quality parameters, during the period from 2014 to 2019, in the main sub-basins affluent to the Itapocu River, through an analysis of technical monitoring reports. Several parameters as thermotolerant coliforms,Escherichia coli,biochemical oxygen demand (BOD5), total phosphorus, total ammonia nitrogen, nitrate, dissolved oxygen, pH, turbidity, and true color were evaluated. The results of the reports were analyzed considering the Resolution 357/2005 of the National Council for the Environment (CONAMA). Results of the spatiotemporal analysis of the water quality parameters showed a correlation between the predominant land uses in the sampling points along with the registered precipitation regime. Furthermore, suggestions, and improvement strategies for future monitoring programs in the Itapocu river watershed are proposed.
