Classifying non-banking financial institutions based on their financial performance
Authors: Costea Adrian
Published: February 2020

In this paper we evaluate comparatively the performance of non-banking financial institutions in Romania by the means of unsupervised neural networks in terms of Kohonen’ Self-Organizing Maps algorithm. We create a benchmarking model in the form of a two-dimensional map (a self-organizing map) that can be used to assess visually the performance of non-banking financial institutions based on different performance dimensions, such as capital adequacy, assets’ quality and profitability. We use the following indicators: Equity ratio (Leverage) for the capital adequacy dimension, Loans granted to clients (net value) / total assets (net value) for the assets’ quality dimension and Return on assets (ROA) for the profitability dimension. We have excluded from our analysis the other three dimensions used in evaluating the performance of banks, due to lack of data (for the two qualitative dimensions: quality of ownership and management) and irrelevance with the NFIs’ sector (liquidity). The proposed model is based on the Self-Organising Map algorithm which creates a two-dimensional map (e.g. 6x4 = 24 neurons) from p-dimensional input data. The data were collected for eleven non-banking financial institutions for four years 2007-2010, in total 44 observations. Using the visualization capabilities of the Self-Organising Map model and the trajectories we show the movements of the three non-banking financial institutions with the worst performance: the largest underperformer denoted with X, the second largest underperformer denoted with Y and the third largest underperformer denoted with Z between 2007 and 2010.

Authors: Ghiţă Simona-Ioana , Gogonea Rodica-Manuela , Săseanu Simona-Andreea
Published: February 2020

The hotel industry is an important driver in tourism development of a region, with positive effects on economic growth, concentrating to a large extent the regional tourism services. The quality of services in this sector is decisive for improving the hotel activity performance, especially in terms of a competitive environment increasingly well defined. The service quality is directly proportional to the hotel comfort category. In 2018 Romania had 34 five-star hotels and 359 four-star hotels, representing less than a quarter of all hotels (24.32%). They owned just over 30% of the total number of hotel bed-places. This paper provides a statistical analysis of activity in the hotel industry in Romania, focusing on main elements of its performance, in terms of a competitive environment. As a result of a case-study on the employees of high comfort category hotels in Bucharest, the key elements of a performing activity are revealed, in order to obtain a competitive advantage.
Are Teaching and Research activities mutually exclusive? A Data Mining study on European Universities
Authors: Grădinaru Simona , Aldea Anamaria , Beşir Levida , Albu Crișan
Published: February 2020

Universities all around the world operate by following several institutional missions, with a central purpose on teaching and research activities. The importance of each aspect alongside the connection between them provide a disputed topic in the literature, many authors confirming or rejecting the intuitive inverse relationship by using various means, more or less quantitative. This paper aims to examine the teaching and research dimensions of the research-active European universities from a data mining perspective. For each dimension previously considered we employ the K-means Clustering in order to identify the groups of similar higher education institutions and we analyze the insights produced by the results. In addition, we build some target variables considering the teaching and research outputs and we investigate their drivers by employing the Logistic Regression. Furthermore, we explore the controverted relationship between the two institutional missions we considered through the use of Correspondence Analysis. Preliminary results illustrate that the dataset contains two types of universities: a category of very large and prestigious institutions and a second group of small and medium sized institutions, quite different from each other. Interest insights are given by the third part of the study, in which the Correspondence Analysis confirms an inverse relationship between teaching and research activities. Unfortunately, this is very likely a consequence of the time constraint – both activities require the same limited resources and therefore increasing the teaching burden for academics may diminish the time and energy dedicated to research.
A Spatial Econometric Analysis of Health in Romania Augmented with Computer Vision
Authors: Jurchiş Florin-Ionuț
Published: February 2020

The purpose of this study is to analyze the health status in Romania at regional NUTS3 level together with its influential socio-economic factors. Apart from statistical and classical econometrics which are being used in most studies, a spatial analysis has been conducted in order to determine possible similarities and dissimilarities among regions, accounting for the fact that events taking place in a specific area are interrelated with the events in the neighboring regions. The negative distribution of the dependent variable, life expectancy, involves the use of Quantile Spatial Autoregressive Model which also allows to observe the socio-economic and environmental factor influences in different parts of health status proxy distribution. The analysis has led to the conclusion that greater the gaps between rich and poor, or greater the difference between less versus better educated, the greater the differences in health status and life expectancy are. Hence a need for policies designed to reduce territorial health disparities has been identified across Romania’s counties. Moreover, Computer Vision and Deep Learning techniques have been used in order to showcase data collection for urban green spaces variables given that more than half of the globe population is living in urban areas and urban greenery has a high positive influence on health. Using Deep Learning on this particular matter together with the Quantile Spatial Autoregressive Model is an innovative approach that has the main aim of improving the classical econometric modelling.
Characterizing the level of economic development of countries
Authors: Nastu Alexandra , Stancu Stelian , Dumitrache Andreea
Published: February 2020

The main purpose of this paper is to provide an objective analysis of the economic development level of countries. This is done by measuring it through a new index and by classifying the countries in an optimal number of clusters, each group characterizing different levels of economic development. The proposed methodology is based on three steps: creating a composite index (by applying the principal component analysis), establishing the optimal number of development groups (based on the number of principal components and on the hierarchical clustering) and clustering countries into them (with the help of k-means analysis). Therefore, this approach solves the difficulty of classifying the countries, complication that is mentioned in the specialized literature. Also, the paper creates a better understanding on the economic development level of countries, as, usually, the papers examine the economic growth level of countries. The analysis is conducted at the level of 60 countries for year 2015, using 12 indicators from categories that influence economic development (income, inequality, health, education and living conditions). The empirical results revealed that the countries can be grouped in two groups: economical developed countries (approximatively 2/3) and economic developing countries (approximatively 1/3). The countries that are most developed from an economic point of view are: Singapore, Luxemburg and Finland.
Exchangeable models of financial correlations matrices. Bayesian nonparametric models and network derived measures of financial assets
Authors: Opincariu Sorin , Ionescu Stefan
Published: February 2020

De Finetti theorem establishes the conceptual basis of Bayesian inference replacing the independent and identically distributed sampling hypothesis prevalent in frequentist statistics with the much easier to justify in practical settings hypothesis of exchangeability. In this paper we make use of the extension of the concept of exchangeability from sequences to arrays arguing that the invariance to ordering is a much more tenable assumption than independent and identically distributed sampling in the financial modeling problems. Making use of the celebrated Aldous-Hoover representation theorem of exchangeable matrix we construct a Bayesian non-parametric model of the financial returns correlation matrices arguing that a Bayesian approach can mitigate many of the known shortcomings of the usual Pearson correlation coefficient. We posit the correlation matrix to be an exchangeable matrix and construct a Bayesian neural network to estimate the functions from the Aldous-Hoover representation theorem. The correlation matrix model is coupled with a Student-t likelihood (accounting for the heavy tails of financial returns). The model is estimated with a Hamiltonian Monte Carlo sampler. The samples are used to construct an ensemble of networks where each edge is weighted by the size of the correlation between two financial instruments. Various centrality measures are being calculated (betweenness, eigenvector) for each network of the ensemble allowing us to obtain a probabilistic view of each financial instrument’s importance. We also construct a minimum spanning tree associated with the mean correlation matrix allowing us to visualize the most important financial instruments from the universe selected.
Efficiency of SVM classifier with Word2Vec and Doc2Vec models
Authors: Truşcă Maria Mihaela
Published: February 2020

Support Vector Machine model is one of the most intensive used text data classifiers ever since the moment of its development. However, its performance depends not only on its features but also on data preprocessing and model tuning. The main purpose of this paper is to compare the efficiency of more Support Vector Machine models using both TF-IDF approach and Word2Vec and Doc2Vec neural networks for text data representation. Besides the data vectorization process, I try to enhance the models’ efficiency by identifying which kind of kernel fits better the data or if it is just better to opt for the linear case. My results prove that for the “Reuters 21578” dataset, nonlinear Support Vector Machine is more efficient when the conversion of text data into numerical attributes is realized using Word2Vec models instead of TF-IDF and Doc2Vec representations. When it is considered that data meet linear separability requirements, TF-IDF representation outperforms all other options. Surprisingly, Doc2Vec models have the lowest performance and only in terms of computational cost they provide satisfactory results. This paper proves that while Word2Vec models are truly efficient for text data representation, Doc2Vec neural networks are unable to exceed even TF-IDF index representation. This evidence contradicts the common idea according to which Doc2Vec models should provide a better insight into the training data domain than Word2Vec models and certainly than the TF-IDF index.
When a Stroke is not Just a Stroke: Escherichia coli Meningitis with Ventriculitis and Vasculitis: A Case Report
Authors: Ribeiro Barbara , Bishop Peter , Jalili Sima
Published: February 2020

Introduction

Community-acquired Escherichia coli ventriculitis is considered a rare condition. Central nervous system (CNS) infection due to gram-negative bacilli is usually associated with previous neurosurgical interventions. The recent publication of cases of Escherichia coli meningitis and ventriculitis suggests its prevalence may be underestimated by the literature.

Case presentation

A case of community-acquired Escherichia coli CNS infection on a 58 year old patient presenting with altered consciousness but without neck stiffness, nor significant past medical history is reported. Imaging and lumbar puncture findings suggested a complex case of meningitis with associated ventriculitis and vasculitis. Escherichia coli was later identified in cultures. Subsequent multi-organ support in Intensive Care was required. The patient was treated with a prolonged course of intravenous antimicrobials guided by microbiology, resulting in some neurological recovery. The main challenges encountered in the management of the patient were the lack of clear recommendations on the duration of treatment and the potential development of multi-resistant organisms.

Conclusion

Bacterial central nervous system infections can have an atypical presentation, and an increasing number of cases of community-acquired ventriculitis have been reported. Early consideration should be given to use magnetic resonance imaging to help guide treatment. A long course of antibiotics is often required for these patients; however, the optimal duration for antimicrobial treatment is not well defined.
The Effect of Early Childhood Education and Care Services in Latvia
Authors: Kūkoja Katrīne
Published: February 2020

The growing number of studies stresses the importance of social investment at an early age by showing that social investment at this period has the highest returns in human capital. The main instrument of social investment at an early age is high quality early childhood education and care services. The aim of the research was to identify whether the first signs of social investment return could be observed in Latvia, since statistic data showed that there was an expansion of early childhood education and care services over the last decades, especially for children until obligatory pre-school age. Research results showed that positive connection could be observed between pre-school attendance rate and fertility rate, female and overall employment rate, average earning, etc. However, no connection could be observed when it came to education outcomes in the short term. The author recommends conducting more research regarding service quality and investment return in the future.
Quality, Equity, Inclusion and Lifelong Learning in Pre-service Teacher Education
Authors: Sunthonkanokpong Wisuit , Murphy Elizabeth
Published: February 2020

Sustainable Development Goal 4 (SDG 4) focuses on ensuring inclusive and equitable, quality education and lifelong learning opportunities for all. One of the three means of implementation of SDG 4 targets is SDG 4c which calls on countries and donors to significantly increase the supply of qualified teachers in developing and underdeveloped countries. This emphasis on the supply of teachers is in recognition of the fact that the quality of education ultimately depends on teachers. In general, there is widespread agreement that teacher education has an important role to play in the achievement of the SDG 4 targets. However, there has been limited attention in the literature to SDG 4 in a context of teacher education. This paper aims to contribute to the literature on SDG 4 and teacher education. The paper first presents a conceptual framework pertaining to quality, equity, inclusion, and lifelong learning. Next, the framework is applied to the case of Thailand to identify examples of progress the country is making in support of realization of SDG 4 in teacher education. The framework with the four concepts can be applied by researchers to identify examples of progress on SDG 4 in teacher education in other countries and contexts.
ESD for All: Learnings from the #IndigenousESD Global Research
Authors: Kohl Katrin , Hopkins Charles A.
Published: February 2020

Education is recognized a human right for all. Though, Indigenous communities do not yet enjoy their full rights to education and are put at risk of losing their Indigenous culture and identity. A new research initiative, holding dialogues discussing the perceived outcomes of quality education in the eyes of several stakeholders, shows that access and retention in equitable and inclusive quality education as described in SDG 4 are highly valued. The research was jointly developed and carried out by researchers and Indigenous communities in 29 countries. Twenty-first century knowledge and skills are crucial for future Indigenous generations to create their livelihood and successfully engage in both Indigenous community life as well as mainstream society. Learning within formal school systems to understand their Indigenous heritage and keep the connection to their environment despite aspiring modern lifestyles, creates relevance which enhances both learning and retention. Beyond twenty-first century competencies, vital elements of education quality seen as relevant for Indigenous youth are aligned with education for sustainable development and applicable for all learners.

Published: February 2020

Abstract, Dieng Plateau is a highland area with an elevation between 2.000-2.100 meters above sea levels and has been used by people since the Hindu Buddhist period to carry out religious rituals. Its location has extreme weather conditions, complicated accessibility, and the threat of eruption from its volcanic mountains. Nevertheless, the conditions do not deter people to build temple compounds in Dieng Plateau. This research conduct to determine the factors underlying the Dieng Plateau as an area to build temple compounds. This research uses locational analysis which emphasizes two aspects are physical landscape and religious conceptual data. Both data are analyzed and synthesized to get factors regarding sacred and profane spaces that have considered in site selection. The results showed that although the Dieng Plateau provides a variety of natural resources that can be used to people’s needs. The physical landscape of the Dieng plateau is an embodiment of the concept of tirtha or the journey from \profane to sacred space. A journey that has the meaning of self-purification to achieve moksha. Elevation of location is a symbol of the axis mundi or intersection between the human world and the world of god. Religious factors seem to be quite dominant in the consideration of choosing the location of the Dieng Temple Complex. Abstrak, Dataran tinggi Dieng merupakan kawasan dataran tinggi dengan elevasi antara 2.000-2100 m.dpl. dan telah digunakan oleh masyarakat sejak masa Hindu Buddha untuk melakukan ritual keagamaan. Kawasan ini memiliki kondisi cuaca ekstrim, aksesbilitas rumit, dan ancaman bencana erupsi dari pegunungan api Dieng. Meskipun demikian, kondisi alam tersebut tidak menghalangi masyarakat untuk mendirikan kompleks bangunan suci di dataran tinggi Dieng. Penelitian ini dilakukan untuk mengetahui faktor–faktor yang melatarbelakangi dipilihnya dataran tinggi Dieng sebagai tempat untuk melakukan ritual keagamaan. pendekatan yang dipakai adalah analisis lokasional yang menekankan pada dua variabel, yaitu lanskap fisik dan konsep keagamaan. Kedua data dari variabel kemudian dianalisis dan disintesiskan untuk mendapat faktor yang dipertimbangkan dalam pemilihan lokasi. Hasil penelitian menunjukkan bahwa dataran tinggi Dieng merupakan perwujudan dari konsep lokasi, ruang, dan tempat sakral dalam agama Hindu. Lanskap fisik dataran tinggi Dieng merupakan perwujudan dari konsep tirtha atau perjalanan dari dunia profan menuju dunia sakral. Perjalanan yang memiliki makna penyucian diri untuk mencapai moksha. Lokasinya yang tinggi merupakan lambang dari axis mundi atau persinggungan antara dunia manusia dan dunia kedewataan. Faktor keagamaan nampaknya menjadi faktor yang cukup dominan dalam pertimbangan pemilihan lokasi Kompleks Candi Dieng.

Parietal transventricular approach for medial temporal glioma: A technical report
Authors: Kumar Amandeep , Chandra Poodipedi , Kale Shashank
Published: February 2020

Background:

Medial temporal lobectomy (MTLy) poses a surgical challenge due to convoluted anatomy of medial temporal lobe (MTL). Various approaches have been described to access MTL for removing various pathologies. We, hereby, describe the parietal transventricular approach for removing a concurrent medial temporal glioma in a patient with recurrent parietal glioma.

Case Description:

A 40-year-old female operated and diagnosed case of the right parietal anaplastic astrocytoma presented to us with a recurrence in parietal region. In addition, a fresh lesion was observed in the right MTL suggestive of a separate temporal glioma. The patient underwent excision of both parietal and temporal gliomas through the parietal approach only. Complete excision of parietal recurrence and near-total excision of medial temporal glioma was achieved.

Conclusion:

The parietal approach can be used for excision of medial temporal lesions, especially those involving or extending into its posterior limits. In the presence of concurrent parietal and MTL lesions, both lesions can be removed through a single parietal approach rather than a separate approach for MTLy. It offers additional advantages of the preservation of optic radiations as well as the temporal neocortex. The visual orientation of MTL structures is different when viewed from the parietal approach as compared to the temporal approaches. The parietal approach provides in line orientation of medial temporal structures contrary to the perpendicular orientation visualized in temporal approaches. An understanding of MTL anatomy as viewed from a parietal vantage point and its three-dimensional conceptualization is very important to successfully remove lesions of MTL through the parietal approach.

Published: February 2020

The administration of human Epidermal Growth Factor (hEGF) for diabetic ulcer treatment has been known to have high effectiveness because hEGF has mitogenic properties and has been proved to increase epithelial cell proliferation both in vitro and in vivo. However, hEGF in environmental conditions of diabetic ulcers is known to have low stability, so it is necessary to repeat the administration or protect the hEGF using suitable preparation. This study aims to produce a new drug delivery system in the form of chitosan nanoparticle as a therapy for diabetic ulcers. The nanoparticle formulation was carried out by varying hEGF concentrations using the ionic gelation method with sodium tripolyphosphate (Na-TPP) as a crosslinker and Polyethylene glycol (PEG) as a stabilizer. Chitosan-hEGF nanoparticle formed were characterized using particle size analysis, polydispersity index, zeta potential, SEM and TEM, pH, and FTIR to observe the functional groups. Chitosan-hEGF nanoparticle-containing 0.1% chitosan, 0.15% sodium tripolyphosphate (Na-TPP), 2% polyethylene glycol 400 (PEG 400), and 75 ng/mL hEGF has the smallest particle size with an average of 600.6 nm and D90 value of 135.7 nm. Nanoparticle formed were relatively stable with zeta potential reaching +41,29. The results of in vitro testing showed that hEGF 50 ng/mL had an optimal cell viability percentage with a value of 192%.

Ecosystem is having a new physical dimension as evidenced by the increasing contribution from man-made plastics synthesized and consumed by our society. Anthroposphere, a brand new constituent, shall be added into the existing lithosphere, hydrosphere, atmosphere and biosphere as a whole for the ecosystem. This new class of anthropogenically-produced materials is xenobiotic and has its own physical form persistent and building up in the ecosystem. Its occurrence in different ecosystems will increase continuously over time. Its hazards and potentially effects in different ecosystems shall be evaluated with a new framework to advance a better understanding of its long-term impact and the mechanisms involved in the changing world. The impacts from these plastics shall be much more than its non-degradability and the potential hazards as observed and a better understanding based on pure science is required. A new opportunity is ahead of us for a collective and immediate action to assess the new dimension of the anthroposphere in the ecosystems to advance the new knowledge on this research subject.

Kolesterol merupakan zat alamiah dengan sifat fisik serupa lemak yang mempunyai gugus steroid. Kenaikan kolesterol mengakibatkan pengendapan pada dinding pembuluh darah yang dapat menyebabkan penyempitan dan pengerasan pembuluh darah atau aterosklerosis yang dapat meningkatkan resiko terjadinya Penyakit Jantung Koroner (PJK). Flavonoid, alkaloid, steroid, dan tanin pada daun bugenvil diduga dapat menurunkan kadar kolesterol total. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak etanol daun bugenvil (Bougainvillea spectabilis) terhadap penurunan kadar kolesterol total mencit (Mus musculus) yang diinduksi pakan tinggi lemak (PTL) selama 21 hari. Penelitian ini merupakan penelitian eksperimental dengan menggunakan 25 ekor mencit jantan (Mus musculus) terbagi dalam 5 kelompok. Pada kelompok perlakuan dosis I, II, III diberi ekstrak etanol daun bugenvil dengan dosis turut-turut 40 mg/kgBB, 80 mg/kgBB dan 160 mg/kgBB, kontrol negatif diberi Na-CMC dan kontrol positif diberi simvastatin. Pemberian dilakukan peroral selama 14 hari. Hasil penelitian dianalisis menggunakan One-Way ANOVA dan didapatkan hasil p= 0,000. Selanjutnya dilakukan uji Post Hoc Tukey yang hasilnya tidak ada perbedaan signifikan antara kontrol positif dengan dosis III pada hari ke-7 dan ke-14 dengan p= 0,141 dan p= 0,468 (p>0,005). Sehingga dosis efektif ekstrak etanol daun bugenvil yang dapat menurunkan kadar kolestrol total pada mencit yang diinduksi PTL adalah Dosis III (160 mg/kgBB).

بعد الأزمة الإقتصادية المدمرة  المعروف بالكساد الكبير (1929) وبقيت آثاره شاخص ومؤثرة حتى (1939)، التي ضربت الإقتصاد الأمريكي، وإمتدت آثارها إلى كل العالم، بادر الرئيس الجديد (فرانكلين ديلانو روزيفيلت) فور فوزه بمنصب الرئاسة في (1932)، بإطلاق حملة إصلاحية إمتدت للمدة (1933- 1938) عرفت بـ(النهج الجديد)، روج لها خلال حملته الإنتخابية.  جاءت تلك الحملة على مرحلتين من البرامج الهادفة والمتخصصة التي غطت شتى القطاعات الإقتصادية والإجتماعية، الأولى عرفت بـ(حملة الجديد الأولى)، والتي إستمرت تشريعاتها بالصدور للمدة (1933-1934)، وتم التركز في برامجها وتشريعاتها على مشاريع الإغاثة الآنية ذات التأثير العاجل والمؤقت لإيقاف التداعيات المتسارعة للإزمة الإقتصادية  من إيقاف إنهيار سوق الأسهم وقيمة العملة تقليص عدد العاطلين عن العمل ولو بصورة مؤقتة. أما (حملة الجديد الثانية) التي إستمرت للمدة (1935-1938) حتى نهاية الركود الإقتصادي (1937-1938) وبروز بوادر الحرب العالمية الثانية. وكان التركيز في برامج هذه الحزمة من الإصلاحات على إيقاف العمل بمشاريع الطوارئ والبرامج المؤقتة، والإنتقال من مرحلة الإغاثة إلى مرحلة الإنعاش الإقتصادي الهادف لإيجاد أسس معالجة جديدة أعمق تأثيراً وأطول أمداً وتأسيس بنية إقتصادية أكثر متانة وفاعلية.

العمارة الدينية في مدينة (دور) كوريكالزو

Published: February 2020

يمكن القول بعد أنَّ عرضنا وصفاً للعمارة الدينية الخاصة بدور كوريكالزو, أنَّ الكشيين قد تأثروا تأثيراً واضحاً بديانة بلاد الرافدين, فعلى الرغم من المستجدات البسيطة التي أحدثوها في مجال السلالم الخاصة بالزقورة والمصاطب المستقلة والتي مثلت حالتين فريدتين لم توجد سابقاً, إلا أنَّ ذلك لا يشير إلى وجود نوع من التطور الخاص بالعمارة الدينية بهذه المدينة التي تمثلهم, إذْ يمكن الاستدلال على ذلك من خلال تخصيص معابد هذه المدينة لإلهة بلاد الرافدين القديمة, واقتباس الكثير من التفاصيل العمارية الخاصة بالبناء.

يمثل حوض وادي شط الاعمى احدى الاودية الموسمية  في منطقة الشيب شرق محافظة ميسان يقع في منطقة الدراسة وفلكياً بين دائرتي عرض 38¯ 31° –  9¯ 32° شمالاً, وقوسي طول  19.5¯ 47°-51¯ 47° شرقاً.أما جغرافياً ، فيقع في شرق محافظة ميسان يحده من الشمال الطيب  ومن الجنوب هور الحويزة  , أما من جهة الشرق فتحده ايران ومن جهة الغرب المشرح ومن الشمال الغربي هور السناف ،ويحتل الوادي مكانه مهمه من حيث الاثر الهيدرولوجي في منطقة الدراسة بعد حوض نهر دويريج الذي يقع شمال وادي شط الاعمى وذلك لما تتسم به المنطقة الشرقية من ميسان في عدم وجود انهار دائمية ممكن من خلالها استثمار الارض في الانشطة الاقتصادية ولاسيما منها الزراعية والصناعية واتضح ان الوادي في جريانه يعتمد على الامطار الاعصارية و قدرة الجريان في الوادي لوصول مياهه الى العراق و استثمارها فضلا عن شكل الحوض الذي يميل الى الشكل المستطيل و هذا يفسر بطئ وصول الموجة المائية الى المصب كما ان الحوض يتسم بكثافة صرف عددية قليلة.
التباين المكاني للخضروات الورقية في شواطئ نهر دجلة في محافظة واسط لسنة 2016 ( الإستعمالات الزراعية لشواطئ نهر دجلة في محافظة واسط )

تُعد الزراعة من أهم الأنشطة الاقتصادية لدورها الكبير في توفير مواد غذائية أساس للسكان ولأنها توفر مصدر دخل للعاملين بهذا القطاع ، ونظرا لتلك الأهمية تخصص لها غالبا أفضل الأراضي الزراعية في المناطق الريفية والحضرية على السواء . وفي مناطق الشواطئ تكون المنافسة كبيرة بين الإستعمالات الزراعية وغير الزراعية وحتى بين الإستعمالات الزراعية نفسها ، وعلى الرغم من ذلك تستحوذ زراعة الخضروات الورقية ومنذ عقود مضت على أفضل الأراضي ضمن المراكز الحضرية لكل وحدة إدارية سواء أكانت مركز قضاء أو ناحية وذلك لحاجة هذه الخضروات إلى القرب من الاسواق كونها سريعة التلف وذات إستهلاك يومي فضلا عن انخفاض أسعارها النسبي مقارنة بالخضر الأخرى لذلك فإنها لاتتحمل تكاليف النقل المضافة الناتجة عن بُعد المسافة .

يستهدف هذا البحث إظهار صورة التوزيع الجغرافي لزراعة الخضروات الورقية في منطقة الدراسة ولتحقيق هذا الغرض تم إعتماد التركيب المحصولي لتوضيح ذلك كما تم إعتماد الدراسة الميدانية (إستمارةالإستبيان والمقابلات الشخصية) لعدم توفر البيانات الرسمية التي تغطي حيثيات موضوع الدراسة مما ساعد على حساب المساحة المزروعة وكميات الإنتاج والإنتاجية لكل محصول بحسب الواقع الميداني.

تبلغ المساحة المزروعة بالمحاصيل الورقية (174) دونما وتشكل نسبة (1,29)٪ من مجموع مساحة المحاصيل الزراعية في منطقة الدراسة البالغة (13453) دونما وتتباين هذه المساحات بتأثير العوامل البشرية لاسيما السياسة الزراعية وحجم الحيازة ورأس المال أكثر من العوامل الطبيعية التي كانت مناسبة جدا لزراعتها . وتبلغ كميات الإنتاج (306,825) طنا /سنويا وتشكل نسبة (0,76)٪ من مجموع كميات الإنتاج للمحاصيل الزراعية في منطقة الدراسة البالغة (40532,88) طنا / سنويا وقد تنوعت هذه المحاصيل الزراعية لتشمل (9) محاصيل وبإنتاجية كبيرة ونوعية جيدة وكثير من هذه الخضروات تزرع على مدار السنة بإستثناء بعضها التي تكون زراعتها في مواسم معينة كالسبانغ والشبنت والريحان والرشاد ويمكن زراعتها بالزراعة المحمية أيضا.

الدلالات الكنائية في الآيات القرآنية الدالة على التعصّب والعناد
Authors: علي عزيز سليم , حمزة عباس يونس
Published: February 2020

يتناولُ هذا البحثُ فنّاً من فنون البلاغة العربية، وهو (فن الكناية)، إذ توجّهت الأنظارُ إلى دراسة هذا الفّن البلاغي منذ نشوء الدراسات البلاغيّة العربية، ومن ثمَّ يبحثُ في دلالات هذا الفنّ البلاغي في الآيات القرآنية الدالة على التعصّب والعناد، فالقرآن الكريمُ يَزخَرُ بالأساليب البلاغية، والتعابير الفنيّة التي أبهرت العربَ قبل العجم، وبذلكَ يُعدُّ القرآن الكريم النصّ الأفضلَ والأغنى لدراسة كلّ فنون التعبير والبلاغة، والبحث في دلالات تعابيره وألفاظه يحتاجُ لجهدٍ جبّار، ولا يَخفى ما يحتاجُهُ البحث في الآيات القرآنيّة من أدوات وإمكانات، وذلك لقدسيّة هذا النصّ ووفرةِ معانيه وتعدّدها، ومناسبته لكُلِّ زمانٍ ومكان .

 حاولت في هذا البحث أنْ أُورِدَ مجموعةً من الأمثلةِ القرآنية التي رأيناها تحمل دلالة التعصّب والعناد، وفيها من المعاني الكنائيّة ما لا تَخفى، وذلك بالرُجوعِ إلى السياق العامّ للآية القرآنية، وإلى كتب التفاسير والبلاغة العربية، للوصول إلى المعنى الكنائي الأقرب والأصح، وتوصّلنا إلى أنّ الكناية في القرآن الكريم، وخاصّة في الآيات الدالة على التعصّب والعناد تخرجُ إلى أكثر من معنى ودلالة، وأكثرُ هذه المعاني هي التهكّم والسخرية من المُتعصّبين المُعاندين، وكشفِ ما في قُلُوبهم من حقدٍ وضغينة تجاه الإسلام والمسلمين، وغيرها من الدلالات والمعاني، وقد قسّمتُ هذا البحث على تمهيدٍ ومحورين، تحدّثت في التمهيد عن التعصّب والعناد في اللغة والاصطلاح بصورة موجزة، والكناية في اللغة والاصطلاح، وكان المحورُ الأول في الكناية عن صفة، والمحور الثاني كان في الكناية عن موصوف .
