Methodology- The study employs a quantitative study to explore the construction industry for building a competitive advantage. Findings- The analysis reveals that the construction industry faces various challenges that can impact project delivery, productivity, and overall performance. there are some common problems in the construction industry. Construction projects often encounter cost overruns due to factors such as inaccurate initial estimates, changes in project scope, unforeseen site conditions, and fluctuations in material and labor costs. Budgetary constraints can lead to financial strain and project delays. Delays in construction projects can occur due to factors like poor project planning and management, inclement weather, labor shortages, regulatory approvals, and issues with subcontractors or suppliers. These delays can result in increased costs, contractual disputes, and dissatisfaction among project stakeholders. Construction sites are inherently hazardous environments, and ensuring worker safety is a critical concern. Failure to comply with safety regulations, inadequate training, lack of safety protocols, and inadequate risk assessments can lead to accidents, injuries, and even fatalities. Effective communication and collaboration among project teams, including architects, engineers, contractors, and subcontractors, are essential for successful project delivery. Inadequate communication, misinterpretation of project requirements, and lack of coordination can lead to errors, rework, and delays. Maintaining high-quality construction standards is crucial, but the industry often faces challenges in ensuring consistent quality control. Conclusion - based upon the analysis findings it may be concluded that the difficulties can turn to competitive advantage with better strategic planning, risk management, and management of resources.

This prevention purpose is to reduce and analyze the impact of the COVID-19 epidemic on foreign trade in harmful products. It is aimed to understand the world created by the planet of the pandemic through the examination of foreign trade data such as exports, imports, trade fees and prices of consumer products from the consumption of the epidemic. In addition, it is planned to analyze criteria such as overview countries and incomplete trade structures, demand, and supply chain, and make an assessment on the difficulties and challenges that arise in this process. Methodology- The data of the study consists of secondary data at the macro level. Foreign trade data belonging to 300215- “Immunological products, put up in measured doses or in forms or packings for retail sale” product group, which is under the main heading of HS 30 pharmaceutical products in the Customs Tariff Schedule and included in the 6-digit product classification, has been used. Relevant data were compiled from the website of the International Trade Center (ITC) trademap.org. As a result of the evaluations made within the scope of the research, interpretations will be made in the light of all the information obtained by giving the current situation of the countries. Findings- The COVID-19 pandemic has had significant impacts on foreign trade in immunization products. During the pandemic, many countries have experienced an increase in demand for immunization products and have sought to strengthen the supply chain to increase production. However, some countries are facing supply challenges due to limited production capacity, supply chain disruptions and fluctuating demand. Conclusion- As a result, the COVID-19 pandemic has had significant impacts on foreign trade in immunization products. Research results show that the pandemic has caused changes in supply and demand arrangements in the sector. Countries have turned to increasing local production to strengthen the supply chain and meet their own needs. This has led some countries to increase exports, while imports have increased in other countries. These research results suggest that the impacts of the COVID-19 pandemic on foreign trade in immunization products are significant and the sector needs to take strategic steps to adapt to these changes. Policymakers should support the sector with measures such as strengthening supply chains and improving trade regulations. Businesses should adapt to changing conditions through strategies such as supply chain management, demand forecasting and market diversification.

This research studies the impact of Brexit on long-run relationship between euro and pound sterling. It is crucial to assess how Britain’s vote to leave the European Union affects long-term relationship between euro and pound sterling because such action may have significant financial and economic implications on both economies (Diez et al., 2019; Korus & Celebi, 2019; Nagarakatte & Natchimuthu, 2022). Methodology- This study utilizes daily trade-weighted real effective exchange rate indices for euro (EUR) and pound sterling (GBP) over the period of January 1, 2013 to December 31, 2019 to investigate the impact of Brexit referendum took place on June 23, 2016 on the long-run relationship between euro and pound sterling. We exclude European sovereign debt crisis and pandemic periods. As stated previously, this study considers June 23, 2016 as the reference to assess the impact of Brexit on the relationship between currencies. Therefore, our analysis involves three periods including full sample period, pre- and post-Brexit. Empirical investigation relies on residual augmented least squares (RALS) based approach. Due to Im & Schmidt (2008), Im, Lee, & Tieslau (2014), and Lee, Lee, & Im (2015), we use RALS-based unit root test and cointegration analysis. While traditional tests (augmented Dickey-Fuller unit root and Engle-Granger cointegration) assume that error terms are normally distributed, which is a very strict assumption, RALS-based tests relax that condition. We also conduct Granger (non-) causality test proposed by Toda & Yamamoto (1995) to investigate the direction(s) of possible causalities between euro and pound sterling for each period. Findings- RALS based unit root test results suggest that the time series of exchange rates contain unit root for full sample, pre- and post-Brexit periods. The only exception is the time series of sterling pound is I (0) in post-Brexit period. According to the unit root test results, we can conclude that foreign exchange markets in both economies follow weak form efficiency for all sample periods. However, this is not valid for the sub sample where the time series of pound sterling is stationary at level, in post-Brexit. RALS based cointegration test results show that there is no cointegration between the time series of EUR and GBP. This general result is confirmed by both models, RALS ADL and RALS EG2. However, we observe a cointegrating relationship between two currencies in post-Brexit period when we treat GBP as the dependent variable. According to the Granger non-causality test results, we fail to reject null hypothesis and conclude that there is no causality running from EA to UK and vice versa for all sample periods. Test results reveal one exception. In the post-Brexit period, EUR Granger causes GBP implying that the past values of EUR are useful to forecast ","PeriodicalId":15124,"journal":{"name":"Journal of Asian Finance, Economics and Business","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135249281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is seen that youth unemployment is one of the important problems in Turkey and the possibility of not being able to find a job for young people creates a worrying situation. Employability is an individual's perception of their chances of finding a job. It is thought that one of the features that can be beneficial for individuals to cope with the process of finding a job is psychological capital. This research aims to test the effect of the concept of psychological capital, which consists of hope, optimism, self-efficacy and resilience dimensions, on perceived employability on a student sample. Methodology- In this study, data were collected using a structured questionnaire. The questionnaire consisted of psychological capital scale, perceived employability scale and demographic information section. 219 students studying in the department of business administration of a state university participated in the study. Participants are between the ages of 17-27. The data were obtained between September 2022 and January 2023 with convenience sampling method and online survey application. Findings- In the study, first of all, the factor structures of the variables were determined by confirmatory factor analysis. Then, the relations between the variables were examined by correlation analysis and it was seen that each sub-dimension of psychological capital had an effect on perceived employability. As a result of the regression analysis performed to test the hypotheses, it was seen that only the dimensions of self-efficacy and optimism had the effect of explaining the perceived employability. Conclusion- In this study, it was seen that students' beliefs that they will be successful and their thoughts about getting positive results increase their perceptions about finding a job. Although this result is consistent with the findings in the literature, it differs from previous studies in that resilience and hope do not have a positive effect. Research shows that optimism and self-efficacy can be increased by education and various learning methods. In this context, it is thought that the trainings to be provided by universities and non-governmental organizations will enable students to better cope with the labor market. Future studies may offer a broader perspective by examining the role of mediators and moderators in the relationship between self-efficacy and optimism and perceived employability.

Method- The relationship between foreign investor portfolio sizes and BIST-100 return index was examined based on quarterly periods covering the years 2010 and 2021. While the data on foreign portfolio sizes and the number of foreign investors were obtained from the central registry, data on the BIST-100 return index were obtained from the official website of the Central Bank. In the study, first of all, it was tested by correlation analysis whether there was a significant correlation between the data. If there is a relationship between the data, the direction of the relationship was investigated using the Granger Causality test method developed by Granger (1969), and econometric methods such as unit root test and stationarity analysis were used to make sense of the findings. Findings- The causality direction from BIST-100 index to Foreign portfolio value was determined by reaching the one-way causality relationship that the stock returns (BIST-100 return index) are the cause of the foreign investor portfolio value. Therefore, in this research, it is concluded that the performance of the stock market in Turkey acts independently from the portfolio values of foreign investors. Conclusion- Considering the dynamics and structural features of the financial markets in Turkey, the impact of the sectoral and company-level investments of foreign investors may differ according to the general stock returns. Therefore, although these results do not definitively show that there is no effect of foreign investors, they may reveal different dimensions of the effect of foreign investors, as will be discussed in this research.

Methodology- Cluster analysis is carried out and interpreted to classify the average amount of waste collected per capita in provinces in Turkey and the ratio of the number of municipalities in each province providing waste services to the population of municipalities. The data used in the analysis is obtained from the table published for the year 2020 by scanning waste statistics on the Turkish Statistical Institute website. Findings- In the study, in line with the objectives of sustainable development, the average amount of waste collected per capita in 81 provinces throughout Turkey and the ratio of the number of municipalities in each province providing waste services to the population of municipalities are made. As a result of the analysis carried out, 81 provinces are collected in 5 clusters, while there are 23,13,27,11 and 7 provinces in the clusters. Conclusion- Sustainability emphasizes that the needs of future generations should not be ignored while meeting the needs of today. At the United Nations Sustainable Development Summit, an action plan was adopted that includes the objectives to be followed for the welfare of people around the world and the tools necessary to achieve these objectives. In this study, municipalities providing waste services in Turkey are evaluated in order to significantly reduce the production of solid waste through prevention, reduction, recycling and reuse until 2030, which is within the scope of responsible production and consumption within these purposes, which Turkey also supports. As a result of the analysis, it has been evaluated that the municipalities in which provinces are in the same group that show similarities in the scope of waste service. It is thought that the findings obtained will provide information as preliminary research for those who will work on this subject and will set light on the evaluations and comparisons to be made on a provincial basis.

Since the focus of the regulations is on \"independent auditing and ethical rules\", examining this issue constitutes the purpose of the study. Methodology- The method of the study is to consider the audit institutions and concepts developed for the prevention of risk in the historical development process, to reveal the importance of independent auditing and ethical principles in terms of stakeholders and the social environment, and to evaluate the subject in a whole, based on the literature. Findings- In preventing risks; It has been determined that audit activities are carried out under three headings: public audit, internal audit and independent audit. In independent auditing, which provides assurance regarding the reliability of financial data and statements, ethical principles are a prerequisite for ensuring the public interest. When we look at the historical roots of the concept of independent auditing and ethical principles; The emergence of financial reporting and auditing scandals behind the sudden bankruptcies of international companies such as Enron, World Com, Xerox, Lucent in the USA and Parmalat in the EU has shaken the trust in capital markets, company management, financial reports, independent audit companies and auditors. The need to re-establish public confidence in the markets and to introduce regulations regarding the transparency, honesty and financial information disclosure responsibility of public companies necessitated institutional structuring and regulations. In this context, the Treadway commission, established in 1985 in the USA, prepared the Sarbanes-Oxley Act (SOX) in 2002, and based on this law, the Public Company Accounting Oversight Board (PCAOB) was established to monitor the accounting sector in order to protect the interests of public company investors. International Supreme Audit Institutions have published the Code of Ethics Standard (ISSAI 30). In parallel, the Public Oversight Institution (KGK) and Capital Markets Board (SPK) in Turkey published the \"Corporate Governance Principles\". Conclusion- In order to prevent risks, independent auditing based on ethical principles, on the one hand, ensures the protection of stakeholders and public interest; On the other hand, it will contribute to the successful continuation of the activities of the related enterprises. The trust and transparency to be provided in the investment environment will be the guarantee of the development of national and international economies in general and the increase of social welfare and the dynamic of development.
