Government expenditure and economic growth in ASEAN-5: long -run tendencies and short-term adjustment.

A question of whether the government should intervene to correct for short-run fluctuations in economic activity has always been an interesting topic for economists. This paper investigates the impact of government expenditure on the economic growth in ASEAN-5 countries during 1980-2006 by using Pooled Mean Group. To examining both short run and long run effects, findings demonstrate that a large government expenditure influences the economic growth of countries negatively. This negative impact may be a sign of the lower productivity of the capital input in ASEAN-5 economies with a large government expenditure

The Economic Impact of Lower Extremity Amputations in Diabetics. a Retrospective Study From a Tertiary Care Hospital of Faisalabad, Pakistan

Background: Among the various complications of diabetes, lower-extremity amputation due to diabetic foot is a common problem. In Pakistan, 6-7% of patients with diabetes suffer from diabetic foot ulceration. Objectives: Our primary objective was to explore the frequency of diabetic foot amputations, and the secondary objective was to calculate the economic burden of these preventable surgeries on the health budget of the provincial government. Materials & Methods: It was a retrospective cross-sectional observational study conducted after obtaining approval from the Ethical Review Committee of Allied hospital, Faisalabad Medical University. The data of diabetic foot patients who underwent amputations between July 2017 and December 2017 were retrieved from three Surgical Units (I, II & III), using a purposive sampling technique. All amputations carried out for reasons other than diabetic foot were excluded. The direct medical cost of one diabetic foot amputation was calculated via a local survey of the various private hospitals of Faisalabad. The indirect costs in terms of loss of productivity and disability costs, transport costs, rehabilitation costs were not included in this study. The data were evaluated by using SPSS Version 23. Results: A total of 85 patients were included in our study. The male to female ratio was 2.7 to 1. The mean direct treatment cost for minor amputation was PKR 46926.00 ± 11730.90 ($382.35 ± 95.58), and the mean direct treatment cost for major amputation was PKR 53720.00 ± 12401.24 ($437.71 ± 101.40). Out of 85 amputations, 63 (74%) were major amputations, and the remaining 22 (26%) were minor amputations. The total cost for 63 major amputations was PKR 3,384,360 ($27568.91) and for 22 minor amputation was PKR 1,032,372 ($8409.67). The net cost came out to be PKR 4,416,732 ($35978.59) for all the 85 cases being reported in a tertiary care hospital of Faisalabad for six months. Conclusion: Diabetic foot, a preventable complication of long-term diabetes mellitus, has an economic burden on the hospital budget, which, if adequately addressed via primary prevention programme, can yield not just economical but medical benefits as well

Futures Contracts in Islamic Finance: an Analytical Approach

Futures contracts provide a useful means of reducing risk because these are highly liquid instruments that can be entered into or liquidated at any time. However, the debate on the legitimacy or otherwise of these contracts in the Islamic commercial law continues to invoke different contentions. The paper accentuates the fact that futures contracts are at bottom a new phenomenon of this age which have no precedent or parallel in the conventional law of transactions (muamalat). Therefore their legality or otherwise should be looked into with the Islamic viewpoint of general permissibility in relation to transactions. The paper examines a number of jurisprudential and legal issues such as non-existence of the subject-matter, sale prior to taking possession, bai al-kali bil-kali, speculation and hedging, and concludes that futures contracts are allowed to benefit from. However, only hedgers can take advantage of them. These instruments can never be used for purely speculative purposes where making or taking delivery is not intended. Although it is not necessary to pay the complete price to the seller at the time of the contract yet some other precautionary measures such as a bank guarantee or a fair amount of money to be given to the seller should be taken to ensure that pure speculation is scrupulously forestalled and the delivery would certainly be made

Employing Antenna Selection to Improve Energy-Efficiency in Massive MIMO Systems

Massive MIMO systems promise high data rates by employing large number of antennas, which also increases the power usage of the system as a consequence. This creates an optimization problem which specifies how many antennas the system should employ in order to operate with maximal energy efficiency. Our main goal is to consider a base station with a fixed number of antennas, such that the system can operate with a smaller subset of antennas according to the number of active user terminals, which may vary over time. Thus, in this paper we propose an antenna selection algorithm which selects the best antennas according to the better channel conditions with respect to the users, aiming at improving the overall energy efficiency. Then, due to the complexity of the mathematical formulation, a tight approximation for the consumed power is presented, using the Wishart theorem, and it is used to find a deterministic formulation for the energy efficiency. Simulation results show that the approximation is quite tight and that there is significant improvement in terms of energy efficiency when antenna selection is employed.Comment: To appear in Transactions on Emerging Telecommunications Technologies, 12 pages, 8 figures, 2 table

Assessment of Nutritional Status and Its Determinants Among Students of Army Public School, Okara, Pakistan

Background: Malnutrition is a health problem affecting growth and development of young children. Children under 15 years of age are the main victims of malnutrition. Malnutrition is attributed to a series of diverse etiological factors. Objective: To determine the nutritional status of the children of various age groups of school going children of Army Public School and to find out the association of socio-demographic variables and dietary habits with nutritional status. Methodology: It was a descriptive cross-sectional study conducted at Army Public School, Okara. Sample was selected through non-probability consecutive sampling. Duration of study was 6 months (Dec 2017 to May 2018). The study was conducted after getting formal approval from Institutional Ethical Review Board AFPGMI. The children were randomly selected for study from the enrollment register available in the principal's office. Participation in the study was voluntary with guaranteed confidentiality. The participants were given full right to quit study without mentioning reason at any time during data collection. After ruling out the exclusion criteria, 500 children fulfilling inclusion criteria were selected for study. An informed written consent was obtained from all selected children and their parents to take part in the study. Data for the assessment of nutritional status was obtained using anthropometry, biochemical laboratory test and eating habits / food preferences of the children. Results: In our study, mean age of children included in the study was 9.58±1.72 years. Out of 500 children, 252 (50.2%) were male while 248 (49.8%) female. The mean height of children was 134.88±11.69 cm. The mean weight of children was 30.25±8.47 kg. The mean OFC of children was 51.43±1.75 cm. Out of total 500 children, 85 (17%) were having BMI less than 18.5, 338 (67.6%) were having BMI within 18.5–24.9 while 77 (15.4%) children having BMI within 25-29.9. None of child was observed with BMI of ≥30. Among 85 children with below normal BMI, 63 had mild malnutrition (BMI between 17-18.4), 19 had moderate malnutrition (BMI 16-16.9) while 3 had severe malnutrition (BMI < 16) Conclusion: Malnutrition is a significant public health problem among preschool and school going children. And improving socio-economic condition along with literacy of mothers and preventing infections through personal hygiene might help in improving the nutritional status of children

Intracerebral migration of stray bullet leading to sudden and fatal worsening

Gunshot wounds to the cranium are one of the leading cause of death and disability in young adults. Stray bullets are also being increasingly seen in clinical setting. We report a case of a 14-year-old boy who sustained a stray bullet to the cranium during election festivities. He arrived at the health care facility institution nearly 24 hours after the event in good neurological condition. He remained neurologically stable for about 8 hours after his presentation and later on deteriorated due to intracranial bullet migration. This required immediate bifrontal decompressive craniotomy along with right frontal lobectomy. However, the patient could not survive

Bis(N-benzyl-N-methyldithiocarbamato-κ2S,S′)(pyridine-κN)cadmium(II)

The title compound, [Cd(C9H10NS2)2(C5H5N)], features a five-coordinate CdII atom, being coordinated by two nearly symmetrically chelating di­thio­carbamate ligands and a pyridine N atom. The resulting NS4 donor set defines a distorted coordination geometry tending toward square pyramidal. In the mol­ecular packing, centrosymmetric ten-membered {...HCNCS}2 synthons arise as a result of methyl­ene-C-H...S inter­actions. These are connected into layers parallel to (10-2) via weak methyl-C-H...[pi](phen­yl) inter­actions
