The reliability of the support zone of beams formed with the use of ST models
Authors: Buda-Ożóg Lidia
Published: September 2020

The following paper presents the analysis of the reliability assessment of a reinforced concrete beam whose shear zone was formed with the use of various truss models. Model 1 is a truss model that was generated using topological optimization. Model 2 is an intuitive model with vertical, tension bars which represent reinforcement in the shear zone by means of stirrups. Model 3 is a statically indeterminate truss. The conducted analysis of reliability of a support node formed with the use of three substitute trusses of varied topology shows that statically determinate models produce lower structural reliability than statically indeterminate models and thus the optimization of ST models should be considered on multi-criteria basis with the aim of obtaining models that are characterized by optimum stiffness and maximum reliability.
Diagonal crack width towards the experimental results
Authors: Ostromęcki Rafał
Published: September 2020

The results of research on diagonal crack width in a single span RC beams were presented in the article. Eurocode 2 rules do not require the direct control of shear crack width. It is assumed, that reinforcement designed to carry the transverse force is also enough to limit the crack width. Experiments were led on beams grouped into four series differing in the links spacing and area of longitudinal tensile reinforcement anchored on supports. The transverse reinforcement steel was of fyd =500MPa The crack width was measured in the following phases of loading. The force was estimated for every series, which was represented by the load level for which the serviceability limit state should be controlled. Maximum crack width was read for this value of force and compared to the limit of 0,3mm. The conclusion was drawn, that crack width is not a critical factor for beams designed for shear with the use of Eurocode and Polish National Annex.
Serviceability limit states of high performance reinforced concrete beams with hybrid fibre
Authors: Smarzewski Piotr
Published: September 2020

The article presents the results of research and analysis of reinforced high performance concrete beams with steel and polypropylene fibres at service load. The beams were bent in the 4-point model. Research was carried out for three different rectangular reinforced concrete beams in terms of the quantity and the type of reinforcement. The beam B1 was constructed conventionally with reinforced steel rods. The beams B2 and B3, instead of the compressive rods and the stirrups the fibre reinforcement of variable fibre volume percentage was applied. In the tests a non-contact system for three-dimensional measurements of deformation – ARAMIS was used. The analysis of the behaviour of the beams under static load for serviceability was based on: images of cracks, strain and force – displacement curves.

Authors: Dudzik Agnieszka , Radoń Urszula
Published: September 2020

The study concerns the static analysis of rods structures in terms of probabilism. Structural design parameters are defined as the deterministic values and random variables. Random variables are not correlated. The criterion for structural failure is expressed the limits of functions referring to the ultimate and serviceability limit state. The Cornell and Hasofer-Lind index is used as a reliability measure. The primary research method is the FORM method. In order to verify the correctness of the calculation SORM, Monte Carlo and Importance Sampling methods are used. The sensitivity of reliability index to the random variables is defined. The STAND program is used to present the examples of reliability analysis.
The analysis of stresses and displacements in the aluminium structure with replaceable elements
Authors: Potrzeszcz-Sut Beata , Pabisek Ewa
Published: September 2020

The paper concerns the non-linear analysis of stresses and displacements in an aluminium truss tower. The Ramberg – Osgood material model was assumed. This model introduced power type relation between stresses and strains. In order to identify the inverse relation, a neural network was used. Because of the need to strengthen the tower, a number of aluminium bars was replaced by steel bars. The perfect elastic material model was assumed for the steel bars. The analysis of stresses and extreme displacements was performed during the cyclic loading and unloading of the system. Two global unloading processes were considered: elastic and elastic-plastic processes. The relationship between the load factor and deflection of the top of the tower is shown. Analysis was performed using a hybrid FEM/ANN program.

Jaringan Lintas Komunitas Menuju Pembangunan Partisipatif Berkelanjutan
Authors: Nelza Mulki Iqbal Muhammad , Herlia Pramitasari Putri
Published: September 2020

Pembangunan partisipatif di Indonesia untuk mengatasi masalah-masalah kota terutama terkait dengan penanganan permukiman kumuh dan pengentasan kemiskinan semakin digalakkan terutama sejak era desentralisasi dimulai. Desentralisasi sejatinya menawarkan komitmen pemerintah pusat dalam mendelegasikan tanggung jawab pada pemerintah daerah untuk memantik kerjasama multi sektor dan partisipasi masyarakat. Sayangnya, banyak program pemerintah yang melibatkan partisipasi masyarakat di masa awal desentralisasi menemui jalan buntu terutama terkait keberlanjutannya. Kampung Improvement Program (KIP) pada era 1970-1980 menjadi salah satu contoh yang menarik untuk dikaji kembali dengan memberikan perbandingan pada inisiasi pembangunan lingkungan berbasis masyarakat terkini seperti yang dilakukan Arkom (Arsitektur Komunitas) Yogya dan Paguyuban Kalijawi di Yogyakarta.

Paper ini tidak akan mengulangi pembahasan pembangunan partisipatif terkait dengan tingkat kepentingannya, bentuk dan tantangan mengapa hal ini perlu dipertahankan. Namun, memberikan fokus terkait bagaimana menemu-kenali dan menggalakkan inisiasi-inisiasi perbaikan lingkungan berbasis masyarakat pada konteks negara demokratis dan meiliki aspek sosial-budaya yang kental seperti Indonesia. Penelitian pada paper ini merupakan penelitian kualitatif dengan deskripsi analisis melalui pengumpulan data berbasis literatur dan observasi lapangan untuk memberikan gambaran pokok permasalahan yang ada. Hasil komparasi kedua proyek diatas menunjukkan bagaimana peran jaringan lintas komunitas mampu memberikan dampak signifikan dalam mewujudkan pembangunan partisipatif berkelanjutan di Indonesia.

Authors: Afolabi Samuel Oluseyi Ph.D
Published: September 2020

Christ Apostolic Church was the foremost African Indigenous Church in Nigeria and its history dates back to 1918. The growth and expansion of the church in Nigeria was aided by the activities of its youth organisations, prominent among which is the Christ Apostolic Church Students’ Association. This article examines the origin of the Association, its vision, administration and programmes. The article also highlights the various contributions of the society to the growth and expansion of the church via evangelism and church planting, music ministry, establishment of Campus Fellowship Centres, promotion of Christian/formal education, career development and leadership development. The study adopted Matthew Seebach’s theory which is based on active forms of participation of youths in which the involvement of young people results in an impact on a process, influences a decision, or produces an outcome. Data were gathered through the use of structured oral interview, questionnaire, archival materials and bibliographical search.

Exploration des obstacles à l’expansion des SI en Afrique subsaharienne
Authors: BABEI Jean
Published: September 2020

Cette contribution à visées descriptives et quantitatives souligne un paradoxe lié au numérique en Afrique. En effet, selon le rapport Digital Social Media in Middle Africa (mobile et e-commerce) de janvier 2018 par We Are Social et Hoot-Suite, le taux de pénétration d’internet en Afrique centrale est situé à 12%, contre 80% en France. Un rapport de la banque mondiale (2018) indique que seuls 20% des individus ont accès à internet en Afrique. Or la production économique mondiale augmenterait de 1.4 millions de dollars-USA grâce à un usage accru des SI. Une enquête de terrain a été conduite – avant la crise sanitaire liée au Covid19 - auprès d’un échantillon de SARL, afin d’identifier les obstacles à l’expansion des SI dans les activités managériales, en Afrique. Des statistiques descriptives ont été conduites. Elles ont été suivies par des analyses comparées, lesquelles ont révélé au moins sept obstacles.
Déploiement du Financement Participatif de Proximité au Burkina Faso
Authors: Ramde Seydou , Bidan Marc
Published: September 2020

Cet article s’intéresse aux éléments de contexte liés à une opérationnalisation de technologies innovantes telles que le financement participatif de proximité (FPP) en Afrique subsaharienne (Burkina Faso) impliquant des populations modestes dans le cadre de projets concrets (puits, pompes, énergie, plantation, etc.) La recherche est basée théoriquement sur les travaux de Shamba et Livian (2014) et sur ceux de Gallo (2017) et empiriquement sur une démarche qualitative investigant trois communautés villageoises (Arbollé, etc.) au sein desquelles furent testés des dispositifs type FPP. Nos résultats montrent qu'une mécanique d'aide – via les Organisations Non Gouvernementales ou via les communautés religieuses - malgré une efficacité sur l'urgence ont contribué à installer une logique de dépendance face à l’aide extérieure qui ne facilite pas l'implication des populations. Cette aide exterieure inhibe de facto les tentatives d'opérationnalisation du FPP. Toutefois, les apports potentiels du FPP semble entrer en cohérence avec les liens familiaux et la diversité des groupes ethniques notamment s'il est déployé au niveau de ce qu'il est possible de nommer le « bassin de vie ».

Exact Minimum Codegree Thresholds for $K_4^-$-Covering and $K_5^-$-Covering
Authors: Yu Lei , Hou Xinmin , Ma Yue , Liu Boyuan
Published: September 2020

Given two $3$-graphs $F$ and $H$, an $F$-covering of $H$ is a collection of copies of $F$ in $H$ such that each vertex of $H$ is contained in at least one copy of them. Let $c_2(n,F)$ be the minimum integer $t$ such that every 3-graph with minimum codegree greater than $t$ has an $F$-covering.  In this note, we answer an open problem of Falgas-Ravry and Zhao (SIAM J. Discrete Math., 2016) by determining the exact value of $c_2(n, K_4^-)$ and $c_2(n, K_5^-)$, where $K_t^-$ is the complete $3$-graph on $t$ vertices with one edge removed.

Authors: Chun Ji Hoon
Published: September 2020

The problem of finding the largest number of points in the unit cross-polytope such that the $l_{1}$-distance between any two distinct points is at least $2r$ is related to packings. For the $n$-dimensional cross-polytope, we show that $2n$ points can be placed when $r\in\left(1-\frac{1}{n},1\right]$. For the three-dimensional cross-polytope, $10$ and $12$ points can be placed if and only if $r\in\left(\frac{3}{5},\frac{2}{3}\right]$ and $r\in\left(\frac{4}{7},\frac{3}{5}\right]$ respectively, and no more than $14$ points can be placed when $r\in\left(\frac{1}{2},\frac{4}{7}\right]$. Also, constructive arrangements of points that attain the upper bounds of $2n$, $10$, and $12$ are provided, as well as $13$ points for dimension $3$ when $r\in\left(\frac{1}{2},\frac{6}{11}\right]$.

The main purpose of this study is to know the best practices and challenges of private sector in fighting money eating. The study employed the qualitative research method using the documentary analysis and made use of Qualitative Analysis in determining the best practices and challenges of the private sector. Based on the findings, the best practices of private sector are in two themes: Public-Private Sector Partnership and Private Sector Self-Regulation; the challenges of private sector are in two themes: Lack of Cooperation and Conflict of Interest. This implies that the private sector plays an important role in fighting money eating and the challenges of private sector is multifarious.Money eating is not just a public sector matter. As a common basis of money eating for public officials, the private sector portions account ability for money eating. Eradicating money eating by mounting a multi-pronged scheme incorporating liberalization, deregulation, civil service improvement, and institutionalization of a participating line to shared service delivery and its monitoring. Comprising the private sector will not only countenance the progress of supplementary refined and sensitive policy responses to money eating but will also put pressure on the private sector to elevation its own standards of deeds.
Credit Market Quality, Innovation and Trade
Authors: Terra Christina , Vasconcelos Enrico
Published: September 2020

En utilisant un modèle d’équilibre général avec un financement privé de la R&D, nous examinons l’impact de l’ouverture des échanges sur l’innovation, la structure des échanges et le bien-être de deux pays égaux à tous égards, à l’exception de la qualité de leurs marchés de crédit. Nous montrons que l’ouverture des échanges accroît l’innovation uniquement dans le pays doté d’un meilleur marché du crédit, alors que cela a un impact négatif sur l’innovation lorsque les marchés du crédit sont moins développés. En ce qui concerne la structure des échanges, le pays avec le marché du crédit le plus défavorisé importe des biens de haute technologie et exporte des biens traditionnels. En termes de bien-être, l’ouverture au commerce peut réduire le bien-être des individus à court terme, mais à long terme, ils sont tous mieux lotis dans le cadre du libre-échange que s’ils étaient en autarcie.

Pour ce faire, un échantillon composé de 87 titres français de 2010 à 2018 est mobilisé. De manière originale, l’AII est estimée à partir du nombre de fois que les utilisateurs du terminal Bloomberg, qui sont pour la majorité des investisseurs institutionnels, réalisent des recherches sur un titre donné et lisent des articles d’actualité sur une entreprise spécifique. Les résultats empiriques indiquent que l’AII exerce un effet fortement positif sur le degré de liquidité des actions françaises. Classification JEL  : G10, G14.
In absentia

Published: September 2020

Le vote par procuration s’est diffusé au cours des dernières décennies. À partir de l’Enquête participation électorale (Insee, 2017), j’établis que cette modalité alternative au vote direct renforce la participation électorale des classes supérieures et donc les inégalités de participation électorale. Les jeunes adultes s’investissent plus dans la procuration alors même qu’ils forment les cohortes importantes d’abstentionnistes. Le vote par procuration, du moins lors de la séquence électorale de 2017, rend compte de la surparticipation des cadres et des plus diplômés : sans la procuration, leur taux de participation est égal à celui des catégories intermédiaires. Mobilité et ressources sociales sont en interaction : le vote par procuration est la modalité à laquelle ont recours des électeurs mobiles du haut de l’échelle des ressources sociales, la mobilité des moins dotés ayant pour conséquence l’abstention. La procuration rend ainsi possible une participation électorale « à distance ».

Published: September 2020

X-ray images of the lower limb bone are the most commonly used imaging modality for clinical studies, and segmentation of the femur and tibia in an X-ray image is helpful for many medical studies such as diagnosis, surgery and treatment. In this paper, we propose a new approach based on pure dilated residual U-Net for the segmentation of the femur and tibia bones. The proposed approach employs dilated convolution completely to increase the receptive field, in this way, we can make full use of the advantages of dilated convolution. We conducted experiments and evaluations on datasets provided by Tianjin hospital. Comparison with the classical U-net and FusionNet, our method has fewer parameters, higher accuracy, and converges more rapidly, which means the high performance of the proposed method.

Published: September 2020

Catastrophic thrombotic syndrome, otherwise known as thrombotic storm (TS) is an extreme prothrombotic clinical syndrome that presents as rapid onset of multiple thromboembolic events affecting a large variety of vasculature. In recent studies, there has been a correlation of high plasma levels of factor VIII with thrombotic events. We present the case of a young man who exhibited multi-organ failure due to thrombotic storm. A 38-year-old male presented to the emergency department for progressive dyspnea and was diagnosed to have pulmonary embolism. The patient developed respiratory distress requiring intubation and was diagnosed with both an ST-elevation myocardial infarction and right cerebral infarction during the hospital course. The patient expired and autopsy revealed the cause of death to be myocardial, cerebral and renal infarction from widespread vascular thrombosis. Autopsy revealed cause of death to be elevated factor VIII associated thrombotic coagulopathy. Factor VIII level upon autopsy was 375% (55-200%). Although TS is rare, it can be lifethreatening if not recognized early. Survival depends on the prompt initiation and duration of anticoagulation.
Success of Dental Implant Osseointegration in a Florid Cemento-Osseous Dysplasia: A Case Report with 8-Year Follow-Up
Authors: Shadid Rola , Kujan Omar
Published: September 2020

Florid cemento-osseous dysplasia (FCOD) is a rare benign fibro-osseous lesion which affects multiple quadrants and predominantly the mandible. This case report presents a successful implant placement with 8-year of follow-up in a 44-yearold woman asking for a fixed restoration in mandibular right posterior edentulous area. Radiographic images showed lobular, irregularly shaped radiopacities and radiolucencies almost symmetrically observed in the premolar-molar area of the right and left regions of the mandible. The findings of Xray images were attributable to FCOD. Minimally invasive two-stage surgery with strict infection control was followed to place two implants in lower right posterior region. The implants demonstrated clinically rigid fixation and restored successfully after 6 months. A direct functional connection between dysplastic bone and the implant load bearing surface was evidenced by the lack of symptoms, and the lack of soft tissues inflammation or peri-implant bone loss up to 8 years follow-up.

Chi-square analysis revealed that, school auspices was associated with keeping records of doctor’s report [χ2 (1, N = 160) = 7.27, p = .007, ɸ = .227, odds ratio = 2.79, 95% CI (1.4, 5.7)] and having immunization records up to date [χ2 (1, N = 160) = 4.35, p = .037, ɸ = .184, odds ratio = 2.88, 95% CI (1.2, 7.7)]. Private early years’ schools were almost 3 times likely to meet recommended health and safety practices. Two themes identified as explanations to why most early years schools were not requiring copies of doctor’s reports were: “We don’t bother to ask” and “Rare cases, they do bring”.Conclusion: Though early years schools were meeting the recommended standards; they were not previewed to doctor’s report of children’s previous illnesses. This implies that these institutions may not be readily prepared to assist in meeting certain health care needs of the children in their care.Keywords: health, safety, early years schools, Cape Coast Metropolis, GhanaFunding: None declared
Prevalence and clusters of modifiable cardiovascular disease risk factors among intra- city commercial motor vehicle drivers in a Nigerian metropolitan city
Authors: Showande Segun , Odukoya Ibimolade
Published: September 2020

Background: Commercial motor vehicle drivers (CMVDs) have worst health profiles among different occupations, yet the presence of clusters of cardiovascular disease (CVD) risk factors in this group have not been described in a resource-limited setting.Objectives: The prevalence of CVD risk factors and the clusters among CMVDs was evaluated.Design: A cross-sectional descriptive study.Setting: Four motor parks in three local government areas of Ibadan city, Nigeria.Participants: Consented and conveniently sampled 152 intra-city CMVDs aged ≥ 18 years. Main outcome measures: Prevalence of CVD risk factors (hypertension, diabetes, high triglyceride, low HDLc, high waist-hip ratio, central obesity, physical inactivity, smoking, alcohol, and overweight/obesity) and their clusters were determined.Results: All participants were male from 20 – 77 years old. Most of the CMVDs were physically inactive (80, 52.6%), take alcohol (78, 51.3%), and few smokes (35, 12.4%). The prevalence of hypertension, diabetes, hypertriglyceridemia,obesity, and central obesity were 36.2%, 5.9%, 23.7%, 4.6%, and 5.3%, respectively. Four clusters of CVD risk factors in the CMVDs with the prevalence of 36.2%. 33.5%, 17.1% and 13.2% were identified with significant differences (p<0.05) in the risk factors.Conclusion: The prevalence of diabetes, obesity, central obesity, and smoking was low while the prevalence of hypertension and hypertriglyceridemia was moderate among the CMVDs, but the prevalence of alcohol intake and physical inactivity were high. Four distinct clusters of CVD risk factors were observed among the drivers.Keywords: Cardiovascular diseases, Risk factors, Motor vehicles, Commercial vehicle drivers, Nigeria.Funding: The study was self-funded.

Failure of the human host to elicit adequate immune responses to the adult Schistosoma haematobium worm and continuous strong inflammatory responses to the eggs have been the main causes of bladder pathology in chronic Schistosomiasis. Identification of susceptibility biomarkers for schistosomiasis- associated bladder pathology is necessary in order to detect genetic factors responsible for the infection and spread of the disease. The aim of this study was to identify candidate-biomarkers for susceptibility to schistosomiasis and its associated pathologies. A total of 371 adult participants, comprising 130 males and 241 females from Eggua community, Ogun State, Nigeria, were randomly recruited into a cross sectional study from August 2012 to May 2014. They were screened for S. haematobium ova and bladder pathologies by microscopy and ultrasonography, respectively. Human host susceptibility to schistosomiasis and its associated bladder pathologies were determined by PCR genotyping of Interleukin (IL4 and IL13) genes, and glutathione-S-transferase (GSTT1 and GSTM1) genes. The overall prevalence of S. haematobium in the population was 29.3% (108/369). Bladder pathologies were observed in 32.3% (117/362) of the population. Polymorphisms in IL 4-590 and IL 13-1055 were observed in 24.1% and 9.3% schistosomiasis cases, respectively. The IL 13-1055 polymorphism did not indicate susceptibility to schistosomiasis in males (OR 0.7, 95% CI 0.3-2.1) but a slight risk was found in females (OR 1.1, 95% CI 0.7-1.7). Participants with GSTM1 and GSTT1 polymorphisms expressed elevated risks of bladder pathologies (OR = 4.3, 95% CI 2.0 - 9.2 and OR = 4.2, 95% CI 1.5 – 12.0, respectively), with the pathology and schistosomiasis group having more GST polymorphisms than bladder pathologies.

Childhood acute glomerulonephritis in Ibadan Nigeria
Authors: Asinobi A.O. , Ademola A.D. , Nwankwo A.F.
Published: September 2020

Background: Acute glomerulonephritis (AGN) is an important cause of mortality and morbidity in children in developing countries while its  incidence has declined in the developed world. This study was to document its present impact in our setting.Aim: To evaluate the sociodemographic features and clinical outcomes in children hospitalized for AGN in the Paediatric Nephrology Unit of the University College Hospital, Ibadan.Subjects and Methods: This was a descriptive analytical study of children aged 2 to 14 years admitted with AGN between 2007 and 2019. Their sociodemographic data, clinical features, complications and outcome were analysed.Results: AGN accounted for 116 (8.9%) of new renal cases admitted over the period. Seventy-four (63.8%) were male, mean age (SD) was 8.2 (3.3) years and peak age incidence between 5 and 9 years. Average annual hospital incidence rose from 4-5 new cases to 8-9 new cases/annum with an upsurge to 17 cases in 2019. Highest yearly monthly incidence was between June and December. Forty -five out of 50 (90%) evaluated subjects were in the middle/ low socioeconomic classes. Stage 2 hypertension occurred in 30/50 (60%) with hypertensive crises in 24%. RPGN occurred in 6/50 (12%) of cases accounting for 5 of the 8 dialysed patients and 4 of the 5 deaths. The case fatality rate was 4.3%.Conclusion: The study showed a progressive increase in the hospital incidence of AGN.RPGN was a major risk factor for death in children with AGN and therefore requires a high index of suspicion and an appropriate early intervention.

Published: September 2020

The aim of the present study was to determine the best non-linear growth function to describe the growth of Kajli sheep. For this aim, the Brody, von Bertalanffy, Logistic, and Gompertz models were used to describe the sigmoidal relationship between bodyweight and age of the Kajli sheep. The records obtained from the Livestock Experiment Station, Khushab, were collected between 2007 and 2018. The records comprised 9864 age-weight observations (300 for male, 9564 for female, 7392 for single, 2388 for twin, and 84 for triplet lambs), which extended from birth to 12 months old. Candidate non-linear functions were fitted and the curve parameters were estimated by nlsfit (fit non-linear models) function in R statistical package, version 3.6.1. Goodness of fit criteria that were used to evaluate predictive performances of candidate models were adjusted coefficient of determination (R2adj), Akaike’s information criterion (AIC), Bayesian information criterion (BIC) and root means square error (RMSE). The Brody model was the best non-linear function that described the biological growth pattern of all, male, female, single, twin, and triplet lambs. Differences in curve parameter estimates between male and female suggested a definite pattern of sexual dimorphism. Moreover, a higher estimate of rate of maturity in female lambs reflects their early maturity compared with male Kajli lambs. Similarly, the single-born Kajli animals with highest maturity rate were maturing at an earlier age than twins and triplets. This is the first report on the non-linear pattern of visible changes in bodyweight of Kajli sheep from birth to 12 months old.Key words: age, bodyweight, growth curves, regression, sheep

This study was designed to evaluate the nutrient intake, digestibility, degradability, and ruminal characteristics of Sindhi heifers fed diets that contained a combined total of 75% oldman saltbush hay (hereafter saltbush hay) and prickly pear cactus. Eight 12-month old intact male red Sindhi calves (four fistulated and four non-fistulated) with an initial mean weight of 170 ± 5 kg were assigned to 4 × 4 Latin squares, where factors consisted of four diets, namely 15% hay and 60% cactus; 30% hay and 45% cactus; 45% hay and 30% cactus; and 60% hay and 15% cactus, and four times at which rumen fluid was collected. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) intakes in kg/day and NDF in percentage live weight (LW), water intake, salinity, and conductivity increased with hay level. Intake and digestibility of non-fibrous carbohydrates were curvilinear with higher values in diets containing 30% saltbush hay. The apparent digestibility of dry matter (DM) and organic matter decreased linearly as the concentration of saltbush hay increased in the diet. The pH of the rumen fluid was within the acceptable range for favourable microbial growth. The low temperature and high salinity and conductivity indices in the diets should be viewed with caution at higher concentrations of saltbush hay, because of a possible decrease in nutrient absorption and the development of health problems in the animals. Apparent degradability coefficients of DM and NDF were affected significantly by inclusion of prickly pear and saltbush hay in the diets.Keywords: animal nutrition, apparent digestibility, Atriplex nummularia Lindl, Opuntia ficus, ruminal degradation, semi-arid environment
State of Civil Society and NGOs in Bangladesh: Examining the Recent Trends and Changes
Authors: Hossain Abul
Published: September 2020

This paper is the outcome of a revisit study conducted in 2016 in three locations of two districts in Bangladesh. The original   and/ or the 1st study was conducted in the same locations   using same objectives and methods in 2005.   The main purpose   of the revisit   study was to perceive the changes taken place in relation to   the   civil society space and activism, and the state of activism of NGOs.  Qualitative approaches were used in collecting primary data from field and secondary sources were also used.   The revisit study finds that NGOs are increasingly offering support to non - poor borrower groups, and today less emphasis is placed on offering small loans to the disadvantaged. The provision of larger loans (than the micro-credit loans encountered earlier), support to small businesses, and the appearance of migration support loans.  In other respects, civil society space has been reduced in 2016. In 2005 we found rights-based works on the road to room for maneuvering, such as legal aid, we also found a civil society had been more politically focused, with the power to influence local officials in some cases.  The 2005 study also found that with various civil society actors (services, rights, social mobilization and advocacy) a kind of dynamism in the stage, there was an opening of space indeed. On the other hand, the revisit study 2016   observed   the shrinking state of civil society space. Rights-based NGOs and informal civil societies are at significantly reduced state; and it was found the social mobilization by the non-government organizations and agencies has a very slim opportunity to reinstall their activities in civil society space in near future. Extreme political control over institutions and citizens’ rights-based activities may be attributed as the main reasons of halting civil society action in Bangladesh.

Elektronik ticaret, teknolojinin gelişmesiyle birlikte rekabet gücünü artırmak için zorunlu hale gelirken, iş gücü, mekân ve zamandan tasarruf sağlamaya da yardımcı olmaktadır. Bu çalışma, Muğla esnafının elektronik ticarete bakış açısının istatistik yöntemlerle açıklanması amacıyla yazılmıştır. Çalışmanın amacına yönelik olarak esnafa işletmelerini tanımaya yönelik sorular ve elektronik ticaret ile ilgili olumlu ve olumsuz ifadelerin yer aldığı anket soruları yöneltilmiş, ayrıca yüz yüze görüşme yöntemi ve açık uçlu sorularla elektronik ticarete bakış açıları anlaışmaya çalışılmıştır.Anket soruları ve yüzyüze görüşme tekniği, artan rekabet koşullarında küçük esnaf, büyük işletmelere göre temelde altyapı yetersizliği sebebiyle geri planda kalmaktadır.Rekabet üstünlüğü sağlamaları ve tüketicilerin isteklerine cevap verebilmeleri yönünden esnafa elektronik ticaret ile ilgili bilgiler verilmeli. Böylece ön yargılar yıkılarak, devlet desteği ve teşviklerle ticaret sisteminin değişimi sağlanmalıdır.
