IMF\u27s Loan Conditionality: Negative Consequences in the Borrower Country and the Burden of Responsibility
People often think that IFIs, such as the World Bank and the International Monetary Fund are prominent players in the global economy by providing funds to countries in need of development and sustainment of welfare, unfortunately these institutions can cause devastating effects in the borrower country. The harsh conditionality of the IMF plays a huge role in the negative economic consequences incumbent upon the borrower country. Meanwhile, the lack of legal remedies for private individuals suffering from the conditionality aggravates the consequences for these people. On the one hand, conditionality may strain the economy of the borrower country which leads to impeding the governmentโs ability to fulfill their international obligations to provide certain rights to their citizens. On the other hand, there are no available legal remedies for private individuals neither in the international sphere or the domestic one. Internationally, IFIs flee responsibility for the consequences of their policies in the borrower countries by escaping behind the lack of adequate internal remedy mechanisms within these institutions and behind the controversial adherence of the these institutions to the right to remedy established under customary international law and to human rights. Domestically, these institutions cannot be held accountable before domestic courts of the borrower country as they enjoy immunity. So the burden of responsibility for the consequences of policies and conditionality imposed by IFIs is shifted from the institution to the administrative bodies of the borrower state who implement the conditionality of the institutions. This paper argues that private individuals suffer from the negative consequences of loans conditionality given by IFIs by causing negative economic effects leading to violations to the rights of private individuals that are supposed to be guaranteed by international conventions due to the burden placed upon the borrower country. It further argues that the lack of remedies deprives private individuals of their rights, as a right with no remedy is no right at all
Evaluation of pediatric bradycardia: A single center experience
Background: Heart rate is an integral part of the clinical assessment of the children with acute illness and is commonly used in pediatric early warning scores. Objective: The aim of this study was to assess our current practice for evaluation and management of bradycardia in children. Patients and methods: The study was conducted in Pediatric Arrhythmia Clinic, Neonatal Intensive Care Unit and Pediatric Intensive Care Unit from March 2020 to August 2021. 61 Neonates and children aged from 1 day to 18 years presenting with bradycardia were included in this study. Predeath bradycardia was excluded. Full medical history, physical examination, basic investigations, 12 leads ECG and echocardiography were performed to all patients. Thyroid function tests, 24 hours Holter monitoring, and stress ECG were done if indicated. Results: 61 patients were included in the study. Heart rate ranged from 44 to 94 beat/minute with mean 69.44 beat/minute, the most common form of presentation was abnormal echocardiography. Hypocalcemia was present in 85.2% of patients. 70.5% of patients had sinus bradycardia, 13% had complete heart block (CHB),10% of patients had long QTc Syndrome with sinus bradycardia, 3.3% had 1st and 2nd degree heart block, 1.6% had ECG changes of ALCAPA with sinus bradycardia and 1.6% had ventricular ectopic. Conclusion: It could be concluded that bradycardia in children needs accurate assessment to rule out the need of acute intervention and to decrease the risk of life-threatening conditions
The efficacy of plant based diets on growth potential, energy utilization, nutrient digestibility, leg bone development and litter quality of meat chickens
Both plant and animal ingredients are used commonly to formulate balanced diets for poultry. Although many changes have been occurred in the genetics, nutrition and feeding of modern meat chickens, free selection and indiscriminate uses of feedstuffs for the non-ruminant animal diets can be hazardous due to the emerging threat of diseases outbreak via animal by-products. Besides this, many other concerns of including animal ingredients in poultry diets such as high price, zoonotic effects, ban on uses, food safety and product quality etc., encourage the poultry integrators to use merely vegetable feedstuffs for diet formulation excluding animal by-products. Exclusive use of plant ingredients into poultry diets might offer potential beneficial effects for optimizing poultry products. Poultry industry may be benefitted by using these cheap sources of vegetable ingredients for quality, safe and organic meat production. After all, most poultry integrators are looking for alternative ways to streamline production. This is why, currently the search for and the appropriate use of vegetable ingredients demand more research to explore their potential uses in poultry diets including other farm animals. However, despite the advantages of using vegetable feedstuffs in poultry diets, there are some associated problems that can affect the performance of meat chickens. So our current study is focused on to review these limitations of meat chickens fed vegetable-based diet, which include productivity, feed utilization and nutrient digestibility, leg bone health and litter quality of meat chickens
SEISMIC BASE ISOLATION FOR REDUCING SEISMIC RISK OF ARCHITECTURAL HERITAGE BUILDINGS
The paper analyses the applicability of seismic base isolation made of elastomeric bearings for the seismic mitigation of architectural heritage buildings. Due to the inestimable cultural and historical significance any remedial measures into such objects must be selected with care and are usually very limited. In an ideal situation only interventions with minimum visual impacts on the object and maximum potential for restoring its cultural values would be implemented. Historical structures were usually not designed accounting seismic hazard and might be seismically more vulnerable as modern buildings. The paper deals with seismic base isolation as a technique for increasing the seismic resistance of architectural heritage buildings made of unreinforced masonry. Typical base isolation devices represent special bearings that are usually installed bellow the foundations of the structure. If the isolation system is properly designed it can eliminate the need for using more invasive retrofit measures and techniques. The paper presents a relatively simple and computationally less demanding technique for the modelling and analysis of regular unreinforced masonry (URM) structures. This technique is based on the equivalent frame approach, while the complex seismic failure mechanism of masonry piers is expressed by a single failure mode interaction surface (an FMI surface ), taking into account the influence of variation in the pierโs vertical loading, and itโs bending moment distribution. A single failure mode interaction plastic hinge (an FMI hinge ) for each masonry frame element is introduced by combining specific failure modes, taking into account their minimum envelope. In the final part of the work a case study of using base isolation for the seismic retrofitting of an existing three-story masonry building has been conducted. Some results obtained by the N2 method comparing the damage in fixed based and base isolated variant of the test building demonstrate the potential of used techniques for the seismic protection of masonry heritage buildings
Livestock Practices: Traditional Animal Holdings Classification in Qatar 2020 Towards Sustainable Food Security
Background: Traditional animal holdings (TAH) in Qatar face many managerial challenges, such as inadequate usage of land capacity, low levels of animal productivity and low economic returns. The top priority of the Ministry of Municipality strategy is to take care of TAH to ensure the sustainability of this activity and to maximize its role in national food security. To support future policy choices and services provision, the ministry initiated a TAH classification system. In 2020, the Social and Economic Survey Research Institute (SESRI) of Qatar University conducted a comprehensive agriculture census that followed a well-known methodology. The census form consisted of questions that guided the classification of TAH. The aim of this study is to help assess TAH performance using data from the census. Results: The Animals Holdings Classification Index (AHCI) divided the current holdings into one of five categories (A, B, C, D or E) in accordance with seven factors as classification criteria. These factors were levels of land and barn capacity utilization, livestock productivity, economic return, biosecurity measures, husbandry system and usage of technology for animal production. The results showed that most of the holdings fell into categories C and D. The lowest-scoring criteria were commitment to biosecurity measures and economic benefit. We recommended intensifying extension and enacting legislation to organize holdings to comply with biosecurity measures and initiating marketing programs and market outlets for TAH. According to Qatarโs 2021 agriculture census, there are three different types of holdings: roving holdings (mobile), 33.6%; holdings in compounds, 57.6; and holdings outside rural houses, 8.8%. Conclusions: The AHCI not only determines a holdingโs actual productivity capability but also encourages holders to develop and upgrade their holdings. Furthermore, it helps the government fill gaps and provide services based on information and evidence
Occurrence of antibiotic resistant C. jejuni and E. coli in wild birds, chickens, environment and humans from Orang Asli villages in Sungai Siput, Perak, Malaysia
JALILA BINTI ABU/// MOHAMED YOUSIF IBRAHIM MOHAMED,SALEHA BINTI ABDUL AZIZ,ZUNITA BINTI ZAKARIA/// Abdul Rashid,Elmutaz Atta Awad
In developing countries, Escherichia coli and Campylobacter jejuni were found to be the prominent bacterial causes of gastroenteritis in human gastroenteritis, and they also showed an increased trend towards antibiotic resistance. Thus, the study aimed to determine the occurrence of E. coli and C. jejuni in wild birds, chickens, human and environment in villages in Perak and to determine the antibiotic resistance amongst E. coli and C. jejuni isolates. Three Orang Asli villages in Perak were chosen. Wild birds were trapped from nearby areas of the villages. We collected 52 human stool samples, 40 cloacal swabs from wild birds and 42 from chickens. For the environment, samples were collected from water (40 samples), flies (40 samples) and soil (40 samples). Two (5%) flies and 16 (38.1%) chickens were found positive for C. jejuni. Also, a total of 50 (96.2%) humans, 40 (100%) birds, 40 (95.2%) chickens were positive for E. coli and 111 (92.5%) of the 120 environmental samples tested positive for E. coli. The disk diffusion method was employed to determine the susceptibility of C. jejuni and E. coli isolates against ten antibiotics. All of the E. coli (100%) and C. jejuni (66%) isolates were found resistance towards at least one antibiotic. Hundred percent (100%) of the E. coli isolates obtained from wild birds were found to show multidrug resistance (MDR). Campylobacter jejuni isolates from flies and chickens showed high resistance towards nalidixic acid
Rhabdomyolysis in an HIV cohort: epidemiology, causes and outcomes.
BackgroundThe Literature on rhabdomyolysis in the HIV-positive population is sparse and limited. We aimed to explore the incidence, patient characteristics, etiologies and outcomes of rhabdomyolysis in a cohort of HIV-positive patients identified through the Johns Hopkins HIV clinical registry between June 1992 and April 2014.MethodsA retrospective analysis of 362 HIV-positive patients with non-cardiac CK elevation โฅ1000ย IU/L was performed. Both inpatients and outpatients were included. Incidence rate and potential etiologies for rhabdomyolysis were ascertained. The development of acute kidney injury (AKI, defined as doubling of serum creatinine), need for dialysis, and death in the setting of rhabdomyolysis were determined. Logistic regression was used to evaluate the association of peak CK level with the development of AKI.ResultsThree hundred sixty two cases of rhabdomyolysis were identified in a cohort of 7079 patients with a 38,382 person years follow-up time. The incidence rate was nine cases per 1000 person-years (95% CI: 8.5-10.5). Infection was the most common etiology followed by compression injury and drug/alcohol use. One-third of cases had multiple potential etiologies. AKI developed in 46% of cases; 20% of which required dialysis. Thirteen percent died during follow-up. After adjustment, AKI was associated with higher CK (OR 2.05 for each 1-log increase in CK [95% CI: 1.40-2.99]), infection (OR 5.48 [95% CI 2.65-11.31]) and higher HIV viral load (OR 1.22 per 1-log increase [95% CI: 1.03-1.45]).ConclusionRhabdomyolysis in the HIV-positive population has many possible causes and is frequently multifactorial. HIV-positive individuals with rhabdomyolysis have a high risk of AKI and mortality
Cogeneration and community design: performance based model for optimization of the design of U.S. residential communities utilizing cogeneration systems in cold climates
The integration of cogeneration technologies in residential communities has the potential
of reducing energy demand and harmful emissions. This study investigated the impact of
selected design parameters on the environmental and economic performances of cogeneration
systems integrated into residential communities in cold U.S. climates following a centralized or a
decentralized integration approach. Parameters investigated include: 1) density, 2) use mix,
3) street configuration, 4) housing typology, 5) envelope and building systems' efficiencies,
6) renewable energy utilization, 7) cogeneration system type, 8) size, and 9) operation strategy.
Based on this, combinations of design characteristics achieving an optimum system performance
were identified.
The study followed a two-phased mixed research model: first, studies of residential
community design and three case studies of sustainable residential communities were analyzed to identify key design parameters; subsequently, simulation tools were utilized to assess the
impact of each parameter on cogeneration system performance and to optimize the community design to improve that performance. Assessment procedures included: developing a base-line
model representing typical design characteristics of U.S. residential communities; assessing the
system performance within this model, for each integration approach, using three performance
indicators: reduction in primary energy use, reduction in CO2 emissions; and internal rate of
return; assessing the impact of each parameter on the system performance through developing 46
design variations of the base-line model representing changes in these parameters and calculating
the three indicators for each variation; using a multi-attribute decision analysis methodology to evaluate the relative impact of each parameter on the system performance; and finally,
developing two design optimization scenarios for each integration approach.
Results show that, through design optimization, existing cogeneration technologies can
be economically feasible and cause reductions of up to 18% in primary energy use and up to 42% in CO2 emissions, with the centralized approach offering a higher potential for performance
improvements. A significant correlation also existed between design characteristics identified as
favorable for cogeneration system performance and those of sustainable residential communities.
These include high densities, high mix of uses, interconnected street networks, and mixing of
housing typologies. This indicates the higher potential for integrating cogeneration systems in
sustainable residential communities
Left Atrium of the Mature Dromedary Camel Heart (Camelus dromedaries): Microanatomy
The current work was carried out on the left atrium of ten healthy mature camels. The specimens were collected and examined histologically after being fixed in 10% Neutral Buffered Formalin. The atrium was processed till paraffin sections obtained and stained. Microscopically, the left atrium is consisted of three major tunics; the internal endocardium, the middle myocardium, and the external epicardium. The endocardium is the inner layer of the atrial wall and consisting of the endothelial layer of simple squamous epithelium that lining the atrium, subendothelial layer of loose connective tissue supporting the endothelium and the subendocardial layer that connecting the endocardium with the myocardium. Myocardium is the middle layer of the atrium, forming the main mass of the atrial wall. It is sandwiched between an outer epicardium, that covers the atrium, and an inner endocardium, that lines the atrial chamber. It is mainly formed from bundles of the contractile cardiac myocytes; myocardiocytes that arranged in strands or branching columns. The left atrium is externally covered with the epicardium that is relatively thin in comparison with the myocardium and consisting of a subepicardial layer of highly vascularized loose connective tissue and the mesothelium of simple squamous epithelium
