Authors:   Namal University Mianwali, Batool Zunera , Akhtar Hameeda ,   International Islamic University Islamabad, Pakistan
Published: February 2023

Covid-19 has affected financial and stock markets globally. It is one of the biggest natural disasters in known history. It has impacted stock markets adversely. This paper examines the moderating effect of volatility, liquidity, information asymmetry, and disposition effect on stock returns in wake of covid-19 pandemic. Moderated OLS regression technique is used to run the analysis in STATA. The results suggest that covid-19 total reported cases impact returns significantly while volatility and information asymmetry also have a significant effect on returns and strengthen the impact of covid-19 on returns. The disposition effect impacts return negatively and significantly and strengthens the impact of covid-19 total cases on returns while covid-19 total deaths do not have any significant impact on returns and no moderation is proved as such. This study gives insight to managers and investors in emerging markets to consider major shifts in the market during unpredictable events like covid-19. On the academic level, this study provides a stepping-stone for understanding markets better during black swan events (Like covid). The findings are largely in line with the earlier literature on natural disasters. Keywords: Liquidity, Volatility, Disposition Effect, Returns, Information Asymmetry, Covid-19

Foreign relations of Pakistan (Pak) with the United State of America (US) have a very long history of Ups and Downs and remain central to the politics of Pakistan. Pak-US relations also remain part of political and public discourse during elections and during the tenures of different political parties in the Government. Political parties in power or in the opposition are discussed with reference to their approach to foreign policy towards the US. The current study aims at examining how Pak-USA Relations were seen through the lens of media coverage, during PTI Government, taking into account the issues of Military Cooperation; Afghanistan Situation; Regional Disputes; War on Terror; and CPEC. The study is based on the news coverage of Pak-US relations in primetime TV news bulletins of two eminent Pakistani news channels GEO and ARY. The Descriptive Content Analysis method is used as a tool of analysis. Data was collected by watching the news bulletin of GEO and ARY news from August 18th, 2018 to January 18th, 2018. Agenda Setting and Framing approaches have been employed to analyze the news bulletins. All hypotheses are proven statistically by using the “t” test. The finding of this study is that both news channels Geo and ARY give positive coverage related to Pak-USA relations. These news channels have almost the same frames used regarding Pakistan and USA relationships in their 9 pm news bulletin headlines. In these frames, GEO and ARY news channels show that the relationships between Pakistan and the USA were very good during PTI’s regime. Both countries were working bilaterally during this selecting time period. Keywords: Framing, PAK-USA Relations, News Channels, PTI, GEO, ARY

Funerary Artifacts from Roman Ashkelon and the Rockefeller Collections
Authors: Erickson-Gini Tali , Savariego Alegre
Published: February 2023

In 2019, an excavation carried out at the site of Er-Rasm, located ca. 2 km southeast of Tel Ashkelon, revealed evidence of a cemetery of the second to mid-fourth century CE in an area that was built over by a monastic community in the fifth century CE. The finds from the cemetery, a lead coffin decorated with vine scrolls and birds in repeating panels and associated artifacts such as gold threads, are comparable to those unearthed in the same general area in 1926 at Khirbet Khasis, as well as to other lead coffins found in Jerusalem and Ashdod-Yam. In addition, parts of a marble sarcophagus with carved features were discovered at Er-Rasm. These features indicate that the sarcophagus was carved with the scene of the abduction of Persephone, just like the complete example uncovered elsewhere in Ashkelon in 1972.

Authors: Wolff Samuel R.
Published: February 2023

This brief communication brings to light a previously unpublished ceramic fragment of a vessel that is identified as a pot bellows. The fragment was found at Tel Megadim, located in the coastal Carmel region of Israel. The importance of this discovery is that its Middle Bronze Age IIC date fixes the “turning point” between Middle Bronze Age stone pot bellows and ceramic pot bellows, a type that became popular in the Late Bronze Age and later, somewhat earlier than previously suspected.

The objective of this work is to share our experience in providing specialized surgical care to patients coming from stages of medical evacuation with wounds of hollow neck organs. A special military operation (SMO) takes place in an environment different from previous local wars. The nature of military operations and the saturation of the enemy's armed forces with new types of weapons gave a significantly higher number of wounded than previous local conflicts. The predominance of mine-explosive shrapnel wounds, different time intervals from injury to getting to the stage of specialized medical care for wounded with already existing purulent complications of gunshot wounds are the features of the SMO. Wounded with injuries of the hollow organs of the neck, entering the MMCH named after N.N. Burdenko from 3 to 6 days after injury, with already developed purulent complications, require comprehensive intensive therapy and participation in the treatment of specialists of various surgical specialties. An integrated approach with the compliance with the regulations of military-field surgery using new methods of diagnostics and treatment of wounds can improve the effectiveness of therapy and reduce the number of lethal outcomes. This article discusses diagnostic and treatment algorithms for different variants of neck wounds. The experience of the described cases of successful treatment of wounded with injuries of the hollow organs of the neck shows the possibilities of MMCH named after N.N. Burdenko in treatment using various methods, and can be useful to doctors of both the Ministry of Defense and the Ministry of Health of the Russian Federation.

Published: February 2023

The present study aimed to verify the occurrence of displacement of the abomasum (DA) in dairy herds from a high-yielding dairy region of Southern Brazil. Data on breed, age, lactation number, days after calving, breeding system, number of animals, and number of lactating cows in the herd were obtained from 135 cases of DA. A total of 39 herds, and 6,454 cows, including 2,987 lactating cows from the municipality of Palmeira, Paraná State, were included in this study. The overall prevalence of DA was 2.09%, and occurrence of DA during lactation was 4.42%. Left displacement was more prevalent, with 94.07% of the cases. The mean number of lactations and age of the cows were 2.5±1.16 lactations and 50.9±18.5 months, respectively. DA occurred predominantly in the semi-intensive breeding system (68.1% of cases), during the first 4 weeks postpartum (84.4% of cases), in Black and White Holstein-Friesian cows (94.07% of cases), and during the winter (31.1% of cases). Cows with DA in high-yielding dairy farms in Southern Brazil were similar to cows from herds of high-milk-yielding regions of North America and Europe. Multiparous Black and White Holstein-Friesian cows showed the highest prevalence of DA during the transition period, mostly on the left side.

Current Approaches and Problems Faced by Orthopedic Surgeons in All-Inside Arthroscopic Meniscus Repairs
Authors: Turan Kaya , lu Osman , n Tu , abuk Haluk , rer Ramazan
Published: February 2023

Objective
All-inside meniscal sutures are frequently the treatment of choice in arthroscopic practice. However, the literature contains limited evidence of the technical issues experienced during the procedure. We aimed to evaluate the technical difficulties encountered during the placement of all-inside meniscal repair sutures according to the surgeon’s experience and the success rate of the suture placement.
Materials and Methods
We invited orthopaedic surgeons across the country to complete a questionnaire through an online platform. Participants were asked to answer 10 questions about their demographic information, general surgical approach to meniscal tears, and experience with intraoperative complications specific to all- inside meniscus sutures. We performed a correlation analysis using the SPSS program to evaluate the statistical significance of the data we obtained.
Results
A total of 100 orthopedic surgeons participated in our study. Of these, 37% had been working as an orthopedic surgeon for more than 10 years. Twenty-five percent performed more than two arthroscopic knee surgeries per week. Fifty-six percent of the surgeons were protective for the displaced red-white zone meniscal tears. Although 90% of the participants stated that the technique was more effortless, only 12% thought the clinical results were better than the other techniques. More than 50% of the participants indicated that they had difficulty when placing the sutures successfully. The most common problem was the inability to fix the meniscus sufficiently and the deformation of the instruments inside the joint. When we compared the complications according to the surgeon's experience, even among the surgeons who performed more than 100 arthroscopic surgeries per year, 34% had trouble successfully applying these sutures.
Conclusion
Although all-inside meniscus sutures are generally believed to decrease the operative time and to be technically more straightforward, even the most experienced surgeons have difficulty in applying these sutures, and the reliability of these sutures is low.

Authors: nal Zeynep , Bahtiyarca Zeynep , Cankurtaran Damla , z Ece
Published: February 2023

Objective: In this study, it was aimed to detect the presence of Fibromyalgia Syndrome (FMS) and related factors in patients diagnosed by Carpal Tunnel Syndrome (CTS).
Materials and Methods: Demographic data and the features of CTS were noted by applying face-to-face questionnaire method. The existence of FMS in patients with CTS was investigated using the 2016 American College of Rheumatology (ACR) Fibromyalgia Diagnostic criteria. The Fibromyalgia Impact Questionnaire (FIQ) was introduced to patients diagnosed with FMS. Then, the correlations between the incidence of FMS in CTS patients, the presence of FMS and the hand with CTS, the severity of CTS and the existence of FMS, the presence of FMS and the duration of CTS symptoms, and finally CTS severity and FIQ were concurrently examined.
Results: 151 patients included in the study. Bilateral CTS was detected in 89 (58.9%) patients. CTS was mild in 55 (36.4%), moderate in 87 (57.6%), and severe in 9 (6.0%) patients. Concomitant FMS was detected in 73 (48.3%) of all CTS patients. FMS rate is higher in patients with bilateral CTS (p=0.001). No significant relevance was observed between the severity of CTS and the presence of FMS (p = 0.864). The median duration of CTS symptoms with FMS patients was 24 (1-240) months; this period was found to be 12 (1-120) months in those without FMS. No significant relations between the presence of FMS and the duration of CTS symptoms were encountered (p = 0.073). The severity of CTS and FIQ demonstrated no significant difference (p=0.955).
Conclusion: The case of FMS is high in specially bilaterally CTS patients. The fact that there may be common points in the pathogenesis of these two diseases suggests that it should be considered for diagnosis and treatment.

Authors: ERDOGAN MEHMET , ERDOGAN ESRA
Published: February 2023

Aim: The COVID-19 has spread rapidly around the world. Apart from primarily targeting the lungs and causing acute respiratory distress syndrome with severe respiratory symptoms and high risk of death, the disease can also cause damage to other organs such as the heart, kidney, and testis. Studies have shown that men are more likely to get infected by the disease than women and the death rate due to the disease is found to be higher in men. We aimed to show the effects of COVID-19 on sperm parameters.
Materials and Methods: In the study, semen analyzes of COVID-19 patients and healthy control groups were compared according to the presence or absence of PCR-confirmed SARS-CoV-2 positivity in hospital records. Patients with COVID-19 (+) were the patients who had mild disease. A total of 510 participants, 53 COVID-19 patients and 457 healthy control groups. After positivity confirmation of recovered COVID-19 patients using PCR, semen analysis was performed after an average of 157 (24-355) days. Also, in order to evaluate the short-term and long-term effects of the disease, patients were grouped as those with less than 90 days and more than 90 days after receiving the positive PCR result.
Results: While the mean progressive motility of sperm was 41.45 (19.21) in the recovered COVID-19 patients, it was 38.35 (21.74) in the control group. The mean total motility was 55.74 (19.34) in recovered COVID-19 patients, where as it was 51.84 (22.45) in control group. The percentage of normal sperm morphology was 11.45 (5.97) in recovered COVID-19 patients, however it was 11.19 (8.08) in control group. The sperm concentration was found to be 68.60 (56.22) x 106/ml in recovered COVID-19 patients, but it was 74.10 (61.72) x 106/ml in control group. Finally, the mean sperm immobility was 44.26 (19.34) in recovered COVID-19 group, however it was 48.16 (22.45) in control group.
Conclusion: In the study, when the semen analysis results of patients who recovered after COVID-19 and healthy control groups were compared in terms of semen parameters according to the recovery time period, no statistically significant difference was found. More studies are needed to fully understand the effects of COVID-19 on the reproductive system.
Effects Of Shunt Types Used In Idiopathic Normal Pressure Hydrocephalus On Patients' Clinical Outcomes
Authors: Akyol Mehmet , Cetin Ey
Published: February 2023

Background: Idiopathic normal pressure hydrocephalus (iNPH) is a surgically reversible neurological disorder in adults. It is a neurological condition characterized by ventricular enlargement detected on cranial imaging as well as gait disturbance, cognitive decline and urinary incontinence, with no other reason to explain the clinical findings. Ventricular shunting, predominantly ventriculoperitoneal (VP) shunt, has been shown to be successful in relieving symptoms in patients. In this study, we aimed to investigate the effects of two VP shunts used in the iNPH patients treated in our clinic.

Methods: Clinical and laboratory records of 28 patients who underwent VP shunting due to iNPH were reviewed retrospectively via the Enlyl system. A programmable shunt was inserted in 9 (32.1%) and a medium-pressure shunt was inserted in 19 (67.9%) patients.

Results: There was no significant difference between the two shunt types with regard to patient age, gender, and preoperative tests (p>0.05). However, the prevalence of ataxic gait was significantly higher in the Programmable Shunt group compared to the Medium-Pressure Shunt group (p<0.05). On the other hand, no significant difference was found between the shunt types with regard to postoperative examination findings and additional neurological disorders (p>0.05 for both).

Conclusion: In the present study, no significant difference was observed between the shunt types with regard to clinical outcomes and thus both types of shunts were revealed as viable options.

Authors: ALADA H , ALADA MURAT
Published: February 2023

Aim:
Our aim is to present the pregnancy and delivery cases that occurred with successful enzyme replacement therapy (ERT) in our female Gaucher patients, whom we have followed and treated for years.

Materials and methods:
We tried to retrospectively evaluate and present 9 pregnancy and delivery events that occurred with successful enzyme replacement therapy in 4 of our 32 Gaucher's disease (GD) patients, whom we have been following up and treated for years in our clinic. Patient monitoring parameters include regular clinical, biological, and radiological evaluations.We checked our Gauher patients regularly at regular intervals before and during pregnancy for their hemoglobin, platelet, leukocyte, ferritin, blood sugar and creatinine levels.

Results:
4 of the 32 cases were children, age range (4-16 years), 16 women age range (22-68 years), 12 men age range (34-72 years). Four of our cases have not received treatment yet. 12 of the female cases are receiving regular enzyme replacement therapy (ERT) (3 months-14 years). Of the male cases, 9 were receiving enzyme replacement therapy (ERT) (3-9) and 3 were not taking medication. One of our cases gave birth to a total of 4 children, first twins and then two single children with an interval of 3 years. Two of our patients had two deliveries and one of our patients with both Gaucher's diseawe (GD) and systemic lupus erythematosus disease (SLE) gave birth. Pregnant patients came to check-ups more frequently during pregnancy and were followed up and treated with a multidisciplinary approach each time they came. The enzyme replacement therapy (ERT) treatments of the patients were increased during pregnancy as the patient gained weight, and the symptoms that increased during pregnancy were relieved by increasing the dose.

Conclusion:
As a result, in our study, we observed that there was a healthy and successful pregnancy and delivery with enzyme replacement therapy (ERT), which was started at the appropriate time and given at the appropriate dose. Comprehensive studies involving more cases are required in this regard.

The aim of this work is to develop and improve anthelmintics that can contribute effectively to the control of certain new and resistant races of nematodes in the treatment of parasitic diseases in humans. This situation is of increasing concern to the agricultural, medical and health communities. The research carried out is particularly interested in the determination of the lipophilicity of a series of substituted molecules of the benzymidazolyl-chalcone family, molecules with proven activity against worms. This work has enabled us to predict and better understand their biological activities (antihistamines, antifungals, antiallergics, antibacterials and antivirals). It has also allowed us to identify the best anthelmintics that offer a broad spectrum of action, a high degree of efficacy, a good safety margin and a high degree of flexibility of use in order to limit resistance problems. The REKKER, KLOPMAN and IROFF methods and the MOLINSPIRATION software were used to determine the lipophilicity of these molecules. The values obtained for the partition coefficients revealed that these molecules are naturally lipophilic. These results allow us to appreciate the important role of molecular lipophilicity calculation methods in determining the mode of action of bioactive molecules.
Conceptual Mapping of Elements Impacting the Value of Knowledge

Knowledge, being one of the most critical and essential resource of any organization is now unanimously considered as an asset. Yet it has no place in any of the financial statements that can mention its value or volume. Since the true worth of an organization is largely dependent on its capability to generate positive return in the future. This positive return is primarily based on the volume and the nature of knowledge and its efficient use. And the efficient use of knowledge asset is the unique design and proposition of organizational resources which itself depends on the knowledge. Therefore, it is impossible to ascertain the true worth of an organization without determining the value of knowledge it possesses. This research work attempts to present factors that have an impact on the value of knowledge. Data was collected from professionals and decision-makers who have responsibility related to knowledge management. Starting from the desk research, followed by interviews and questionnaire instrument, the data was collected from business managers working in various industries. Various statistical tools were employed to analyze the data and evaluate the identified items and factors. Finally, the two factors were identified after regrouping of items and initial factors through Principal Component Factor analysis. The new factors were named “Strategic Advantage” and “Core Capabilities”. The integration of “Strategic Advantage” and “Core Capabilities” forms the basic framework for valuing knowledge. The findings will lead to further research in knowledge management. Refinement of the suggested model would enable managers to differentiate the most valuable and useful knowledge assets from the least valuable knowledge. Investors would also benefit from the study as it may help them in evaluating/calculating the actual value/worth of an organization.

HRM practices play a vital role in organizational performance of banking sectors. The objective of this study is to determine how Human Resource Management processes have impacted the organizational performance of public and private banking industry in Pakistan, for that purpose, a public bank i.e.  National bank of Pakistan (NBP), and a private bank, United Bank Limited (UBL) was selected. In the current company environment, HRM strategies are essential for two key reasons: talent cultivation and employee motivation. A questionnaire was used to collect quantitative data from both the banks, and the aim of the study was explanatory. The survey was completed by an estimated 270 employees from NBP and UBL from various divisions. The analysis was conducted using SPSS version 22, specifically the Regression and Correlation functions. According to the research, NBP and UBL, Karachi's hiring practices had no bearing on organizational performance. Other HRM strategies, like as training and development, performance evaluation, remuneration, and incentives and recognition, favorably influence organizational performance. According to researchers, the study's results are useful for public and private banking sectors of Pakistan. The results of this study may be beneficial not just to the participating banks, but also to other financial organizations.
How Does Industrial Intellectualization Affect Energy Intensity? Evidence from China

Published: February 2023

Since the 21st century, as the digital economy has flourished and the Fourth Industrial Revolution has deepened, emerging technologies have exerted a significant influence on social development, leading to the rapid informatization and digitalization of society. Therefore, in the digital age, industrial intellectualization and energy intensity may interact. In this study, an industrial intelligent system is constructed considering three aspects, and the relationship is explored between industrial intellectualization and energy intensity from 2006 to 2018 in China. Industrial intellectualization can effectively improve energy efficiency and thus restrain energy intensity with a significant lag effect. In addition, China’s energy intensity is highly spatially autocorrelated and spatially agglomerated. The negative spatial spillover effect of industrial intellectualization on energy intensity is also of concern. Finally, the nonlinear effects of industrial intellectualization on energy intensity are comprehensively analyzed under different levels of economic growth, technological progress, industrial restructuring, educational progress, financial development, and environmental regulation.
How to Value Proved but Undeveloped Petroleum Reserves
Authors: Vielhaber Lawrence M.
Published: February 2023

Proved undeveloped reserves (PUDs) are typically assigned a value of zero when the cost to produce them is greater than the prevailing forward curve. The zero valuation occurs despite the option value contained in even the most expensive PUDs. While PUDs are worthless if spot and forward prices forever remain below the cost to produce them, they have positive value if either the spot price or a contracted futures price exceeds the cost at any time. Since the probability that future prices exceed cost is positive, PUDs have positive option value despite the industry practice.

Zero valuation occurs primarily because financing is unavailable when hedging is contingent on uncertain future outcomes where probabilities cannot be modeled. The failure of models to recognize contingent hedging is a limitation that leads to chronically undervalued PUDs in marginal and sub-marginal price environments. The literature is silent on contingent hedging where financing is dependent on forward curves that will not exist until some future date. This paper introduces a model that addresses these limitations.
How has ESG investing impacted investment portfolios? A case study of the Malaysian civil service pension fund
Authors: Rahman Muhammad Irfan Abdul , Lau Wee-Yeap
Published: February 2023

Environment, social, and governance (ESG) criteria have become important in investment and risk management in recent years. ESG-mandated investment has also been trending among investors. In Malaysia, the ESG-related index known as the FTSE4Good Bursa Malaysia (F4GBM) index was first launched in December 2014. This index prompted fund managers to use the benchmark as a measure of performance. However, there has been a lack of research on ESG-related pension funds. Hence, this study examines the impact of ESG investing on the investment portfolio of the Malaysian civil service pension fund. This pension fund is managed by the Retirement Fund Incorporated (Kumpulan Wang Persaraan Perbadanan; KWAP). Using quarterly data from 2017Q3 to 2022Q3, our results show, first, that KWAP has had a higher proportion of ESG-rated securities than of non-ESG-rated securities over the last five years. Secondly, ESG-rated stocks provide higher returns than non-rated stocks in KWAP's portfolio. Thirdly, ESG-rated securities have lower risk levels than non-ESG-rated securities. This study also found that ESG-rated securities provide a higher return per unit of risk relative to non-ESG-rated stocks. As a policy implication, ESG-rated investment has impacted the pension fund by providing higher returns and lower risk. This study contributes to the awareness of the benefits of ESG investing among state-funded pension schemes.
