Steering Through Uncertainty: Commodity Price Shocks and Pakistan's Automobile Industry

Purpose - Recently, conflicts among countries have caused many economic shocks in the global economy. Commodity price shocks are one of the most essential shocks resulting from these conflicts. Industries like automobiles are always most vulnerable to these shocks. This paper examines the impact of commodity price shocks on the automobile industry of Pakistan. Design/methodology/approach - We used monthly data from July 2008 to June 2020 and employed the SVAR model for our analysis. Findings - The pattern of the response of the automobile industry to commodity price shocks showed that commodity price shocks' impact on Pakistan's automobile industry is dominant on the supply side. Energy, education, and housing price shocks cause an excess supply of automobiles, whereas transportation prices reduce supply. On the demand side, food, clothing, and footwear price shocks negatively affect demand. Originality/value - This study increases the knowledge of the impact of commodity price shocks on the automobile industry and is the first study that addresses this issue in Pakistan. It also provides policymakers guidelines and helps them make policies for the development of the automobile industry accordingly

Religion and Electoral Politics in Punjab: A Case Study of 2018 General Elections

This study is focused on the impact of religion on the electoral pattern of the people of Punjab. Religion as a determinant of voting behavior is best expressed in the votes secured by the religious parties. Thus, religious parties vote in Pakistan and Punjab is studied to build an argument. Religion has a strong impact on human life. It influences each act and attitude of the individual especially in developing countries. In Pakistan; religion has a solid affect in shaping the political attitudes and beliefs of the individuals. It is one of the key elements of politics.2018 general elections saw a sudden rise in the vote bank of religious political parties. It witnessed a 2.17 % increase in the religious vote country wide and 1.32% increase in Punjab. Tahreek Labbaik Pakistan appeared on the scene as a radical Sunni Islamic party, it mobilized the barelvi vote bank to great effect. And it emerged as the third largest party of Punjab, in terms of votes polled. 2018 general elections also witnessed the rise of Milli Muslim League which was a political wing of Jamaat-ud-Dawa, who were previously rejecting the parliamentary form of government and were critical of voting in elections. The increase in the influence of the various spiritual gaddi nasheen in the electoral politics of Punjab was also a prominent factor during the 11th general election

A Secure and Robust Image Hashing Scheme Using Gaussian Pyramids

Image hash is an alternative to cryptographic hash functions for checking integrity of digital images. Compared to cryptographic hash functions, an image hash or a Perceptual Hash Function (PHF) is resilient to content preserving distortions and sensitive to malicious tampering. In this paper, a robust and secure image hashing technique using a Gaussian pyramid is proposed. A Gaussian pyramid decomposes an image into different resolution levels which can be utilized to obtain robust and compact hash features. These stable features have been utilized in the proposed work to construct a secure and robust image hash. The proposed scheme uses Laplacian of Gaussian (LOG) and disk filters to filter the low-resolution Gaussian decomposed image. The filtered images are then subtracted and their difference is used as a hash. To make the hash secure, a key is introduced before feature extraction, thus making the entire feature space random. The proposed hashing scheme has been evaluated through a number of experiments involving cases of non-malicious distortions and malicious tampering. Experimental results reveal that the proposed hashing scheme is robust against non-malicious distortions and is sensitive to detect minute malicious tampering. Moreover, False Positive Probability (FPP) and False Negative Probability (FNP) results demonstrate the effectiveness of the proposed scheme when compared to state-of-the-art image hashing algorithms proposed in the literature

Effects of Fertilizers on Copper and Nickel Accumulation and Human Health Risk Assessment of Vegetables and Food Crops

Despite the fact that fertilizers have been used for millennia for sustainable crop production, this high and considerable dependence on fertilizers heightens environmental concerns with the indirect human exposure due to accumulation of toxins in food chain via soil contamination. The purpose of this study is to evaluate the application of fertilizers to the soil and their effect on the accumulation of copper and nickel in spinach (Spinacia oleracea), garlic (Allium sativum), wheat (Triticum aestivum), maize (Zea mays), and barley (Hordeum vulgare); as well as potential health concerns associated with consuming vegetables cultivated on this contaminated land. Samples of available soil, food crops, and human blood were collected from three different Tehsils: Bhalwal, Sahiwal, and Silanwali and were regarded as site 1, site 2 and site 3 respectively. Urea, farmyard manure, and potassium chloride were delivered to Site 1; urea phosphate, manure, and ammonium sulphate were delivered to Site 2; and superphosphate, ammonium phosphate, and nitrate phosphate were delivered to Site 3. Data was subjected to statistical analysis for computing out ANOVA and correlation. Analysis revealed that minimum copper concentration was found in the soil of T. aestivum grown at Site-1 while the inhabitants of Site 3 had the highest concentration of Cu in their blood. The highest level of HIR was found in the human beings that ate the S. oleracea grown at Site 3. It is strongly advised that fertilizers be used sparingly, as their excessive use can cause human health risks

Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial

Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124. Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid (5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18). Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of 5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98). Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a randomised trial

Pakhtoonwali-ethical code of honor among Pakhtoons

This paper aims to study the Pakhtoon culture and tradition through Pakhtoonwali. Pakhtoonwali is the code of ethics among the Pakhtoons. It is essentially the unwritten code controlling, guiding, and balancing the form, character, and discipline of the Pakhtoon way of life, passed from generation to generation.These traditions serve as a major foundation of Pakhtoon culture, norms, values and codes of conduct. The Pakhtoonwali or the Pakhtoon code of honor embraces all the activities from the cradle to the grave. Almost all the customs and cultural values of Pakhtoons revolve round this unwritten code of honor. Pashtosociety is an honor based society and they believe that a Pakhtoon’s Izzat (honor) lies in adhering the principles of Pakhtoonwali. Thus Pakhtoonwali forms the major foundation of the Pakhtoon social fabric. The data for the study is collected from the Pakhtoon community located in Gutlibagh area of Ganderbal district. This study is based on ethno linguistic approach

Trucut biopsy as a first line diagnostic modality for equivocal or suspicious breast masses: an experience from a teaching hospital in Khyber Pukhtunkhwa

Background and Objective: Trucut biopsy (TCB) is a commonly used technique for histopathological diagnosis of a clinically and radiologically equivocal or suspicious breast mass. This study aimed to determine the sensitivity and specificity of TCB in the diagnosis of equivocal or suspicious breast masses at local tertiary care hospital in Khyber Pukhtunkhwa. Methods: This descriptive cross-sectional study was conducted at the surgical unit of Mufti Mehmood Memorial Teaching Hospital, Dera Ismail Khan, Pakistan. The study included 80 patients who presented with equivocal or suspicious breast masses from September, 2015 to December, 2020. The patients underwent TCB and after the histopathology report, they were followed by a definitive surgical procedure. The histopathology diagnosis following TCB was compared with the histopathology report of postsurgical specimen to determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of TCB taking post-surgery histopathology as a gold standard for diagnosis. Results: Out of the 80 patients, 68 (85%) were found to have a primary breast malignancy, while 12 (15%) patients were diagnosed with non-malignant lesions. There were only two false negative cases. The specificity and PPV of TCB were found to be 100%, while a sensitivity of 97% and a NPV of 85.7% was calculated. Conclusion: TCB is a valid, reliable, and simple first line minimally invasive method to determine the diagnosis of breast masses that are clinically and radiologically (breast imaging-reporting and data system 3 to 5) equivocal or suspicious.</p
