THE TOPIC OF KOSOVO IN THE WORK OF ISMAIL KADARE 伊斯梅尔·卡达雷工作中的科索沃问题
IF 0.6 Q4 BUSINESS Pub Date : 2021-05-31 DOI: 10.33642/IJBASS.V7N5P1
Prof.Asoc.Dr. Besim Muhadri
Ismail Kadare (1936) is one of the most famous writers of contemporary Albanian literature. He is the author of dozens of books of poetry and prose, which have been translated into 45 languages of the world, making him one of the most translated Albanian writers, but also the most famous in the world. He is a laureate of many international awards and several times nominated for the Nobel Prize for literature.In my paper, I will address the aspects of his contribution in addressing the topic of Kosovo, both in the field of poetry and in that of prose and journalism. With this topic, in addition to some poems, he has published the novels "Krushqit janë të ngrirë", "Tri Këngë zie për Kosovën", as well as the publicist books "Ra ky mort e u pamë", "Bisedë mes grilash" and "Çlirimi I Serbisë Nga Kosova". Kadare's treatment of the Kosovo issue on an artistic level has made the violation of the national rights of the autochthonous Albanians of Kosovo by the Serbian occupying regime, in particular, and the issue of Kosovo, in general, sensitized in the international arena.The methods used in this paper are that of analysis and synthesis.
伊斯梅尔·卡达雷(1936)是阿尔巴尼亚当代最著名的文学作家之一。他著有数十本诗歌和散文书,这些书已被翻译成世界45种语言,使他成为翻译最多的阿尔巴尼亚作家之一,也是世界上最著名的作家之一。他是许多国际奖项的获得者,并多次获得诺贝尔文学奖提名。在我的论文中,我将阐述他在诗歌、散文和新闻领域对科索沃问题所作贡献的各个方面。关于这个主题,除了一些诗歌,他还出版了小说《Krushqit janëtënggrirë》、《Tri Këngëzie për Kosovën》,以及公关书籍《Ra ky mort e u pamë》,《Bisedëmes grilash》和《Çlirimi I SerbisëNga Kosova》。卡达雷在艺术层面上处理科索沃问题,特别是塞尔维亚占领政权侵犯科索沃当地阿尔巴尼亚人的民族权利的行为,以及整个科索沃问题,在国际舞台上引起了关注。本文采用的方法有分析法和综合法。

Purpose: This study set out to empirically examine the relationship between inventory management and private hospitals' financial performance in Western Uganda. Methodology: The study adopted a positivist approach and a cross-sectional research design to collect data from 32 Private hospitals in Western Uganda. The study used a closed-ended questionnaire to collect data and simple linear regression for data analysis. Findings: Results revealed inventory management as a significant predictor of private hospitals' financial performance in Western Uganda. The study recommended that private hospitals adopt robust and scientific inventory management systems and models that aim to optimise stock levels and minimise costs if they are to achieve substantial financial performance. Contribution to Practice and Policy: The study has deep-rooted the urgent need for private hospitals to adopt more stringent inventory management systems that will ensure adequate stock levels, minimise costs and enhance superior financial performance. However, the study was positivistic, thus subject to methods bias that could have affected the results' validity.

Service outsourcing is a strategy that has recently been used to create the ground for the optimal use of the expertise of the organization’s staff. The purpose of this study is to investigate the relationship between outsourcing activities of Isfahan province’s bureau of taxation affairs and their organizational performance. The research method is applied in terms of purpose and terms of nature, and the method is descriptive-correlation with the survey method. For this purpose, a sample of 349 subjects was selected among 3750 employees of Isfahan province’s bureau of taxation affairs by the multi-stage cluster sampling method. To collect data, the organizational performance questionnaire and outsourcing questionnaire were used and to assess the validity and reliability of the questionnaire, content validity and Cronbach’s alpha method was used, respectively. With applying structural equation modelling, Lisrel software was used to analyze the data and test the hypotheses. The results of the study revealed that there is a significant relationship between the outsourcing of the Isfahan province’s bureau of taxation affairs and their organizational performance. Accordingly, outsourcing activities have a significant relationship with fast-track activities, increasing the quality of services, using employee expertise, increasing customer satisfaction and reducing organizational costs. The feedback on the results of this research helps the Isfahan province’s bureau of taxation affairs to eliminate the shortcomings of outsourcing activities. Second, the use of the effects and consequences of outsourcing activities effectively improves organizational performance through its relationship with increasing the quality of services, reducing organizational costs, fast-track activities, upgrading customer satisfaction, and increasing the specialized skills of employees using employees’ expertise.

Aim: Despite years of empirical research, the nexus between banks development and the stock market with economic growth is still controversial. This study examined the impact of the stock market and banks development on the firm’s growth in Pakistan. The sector of non-financial firms chosen for analysis and financial firms ignored because of different structure. The sample of 45 firms listed on the Pakistan Stock Exchange (PSX) from the period of 2014-2019 used for the analysis. The sample has been selected based on the firm’s market capitalisation and random effect model to estimate both institution development and firm growth. We controlled the firm’s profitability, interest, and inflation. The results are robust to the Estimated Generalised Least Squares (EGLS) method. Results showed that significant positive relation exists between stock market development and firm growth, while a negative association exists between banks development and firm growth. Furthermore, control variables (profitability, interest, and inflation) have a significant negative impact on firm growth. The findings contribution in literature with perspective to Pakistan because prior studies done related to developed countries. Policymakers may use this study for making policy related to firms and economic growth.
目的:尽管进行了多年的实证研究,但银行发展和股市与经济增长之间的关系仍然存在争议。这项研究考察了股票市场和银行发展对该公司在巴基斯坦的增长的影响。选择进行分析的非金融企业部门和因结构不同而被忽视的金融企业部门。分析使用了2014-2019年期间在巴基斯坦证券交易所上市的45家公司的样本。样本是根据公司的市值和随机效应模型选择的,用于估计机构发展和公司增长。我们控制了公司的盈利能力、利息和通货膨胀。结果对估计广义最小二乘法(EGLS)具有鲁棒性。结果表明,股票市场发展与企业成长之间存在显著的正相关关系,而银行发展与企业增长之间存在负相关关系。此外,控制变量(盈利能力、利息和通货膨胀)对公司增长有显著的负面影响。研究结果对巴基斯坦的文献有贡献,因为之前的研究与发达国家有关。政策制定者可以利用这项研究制定与企业和经济增长相关的政策。

Kalman filter (KF) provides optimal beta estimate with linear models where the noise covariances are known a priori. Noise covariance adaptation-based adaptive KFs (AKFs) have also been used to get these beta estimates. These AKFs suffer from one typical problem, namely inadequate noise filtering. This paper explores some new formulation of such AKFs to solve this problem in addition to applying other related existing formulations. The proposed methods have been analysed through simulation study along with empirical performance verifications through VaR backtesting, expected shortfall analysis, and in-sample performance analysis. Results show that two new and one existing AKFs are successful to provide smooth beta estimates.
卡尔曼滤波器(KF)提供了具有线性模型的最优贝塔估计,其中噪声协方差是先验已知的。基于噪声协方差自适应的自适应KF(AKF)也被用于获得这些β估计。这些AKF存在一个典型的问题,即噪声滤波不足。除了应用其他相关的现有配方外,本文还探索了这种AKF的一些新配方来解决这个问题。通过模拟研究以及通过VaR回溯测试、预期缺口分析和样本内绩效分析进行的实证绩效验证,对所提出的方法进行了分析。结果表明,两个新的和一个现有的AKF成功地提供了平稳的贝塔估计。

A serious constraint of data availability over flood-prone areas in India limits the potential of carrying out hydrodynamic flood modelling studies. Such difficulties are encountered because of a lack of high-resolution topography, cross-section data of the rivers, and sufficient and accurate calibration and validation data sets. The present study addresses the problems faced in performing a comprehensive 1D-2D coupled flood modelling over a flood disastrous region Jagatsinghpur, Odisha, India. The constraints faced in terms of hydraulic parameters such as water level, discharge, and geometric parameters such as river geometry are investigated. The simulations were performed for a severe flood event in 2011 that incurred heavy socio-economic losses in the district. The establishment of a modelling platform for flood simulation shall elucidate the major constraints faced in hydrodynamic modelling for such flood-prone areas with poor data availability.
印度洪水易发地区的数据供应严重受限,限制了开展水动力洪水模拟研究的潜力。由于缺乏高分辨率的地形和河流断面数据,以及足够和准确的校准和验证数据集,因此遇到了这些困难。本研究解决了在印度奥里萨邦Jagatsinghpur洪水灾害地区进行全面的1D-2D耦合洪水建模所面临的问题。研究了水力参数(如水位、流量)和几何参数(如河流几何)所面临的约束。该模拟是针对2011年给该地区造成严重社会经济损失的严重洪水事件进行的。洪水模拟建模平台的建立,需要阐明在这些数据匮乏的洪水易发地区进行水动力建模所面临的主要制约因素。

The global financial world has been experiencing increasing complexities in the design and construct of financial instruments, wherein the average retail investors need to be well informed and aware of the risks about the evolution of financial products and financial system. The global financial crisis of 2008-2009 is evident to the fact that traditional methods of financial advisory involving the use of human intermediaries and financial advisors is not an infallible method to determine one's financial decision or risk management. Almost a decade since the crisis, the advancement of financial technology in the form of robo-advisors and the use of data and visual analytics have completely transformed the way the retail investors make their financial decisions and also in the sphere of risk management of these investors. The study qualitatively analyses the use of the use of analytics and robo-advisory in determining retail investors' financial decisions and risk management by doing a systematic and an exhaustive literature review on the latest and the past studies on the topic.
全球金融世界在金融工具的设计和构建方面日益复杂,其中普通散户投资者需要充分了解和意识到金融产品和金融体系演变的风险。2008-2009年的全球金融危机很明显地表明,传统的财务咨询方法,包括使用人力中介和财务顾问,并不是确定一个人的财务决策或风险管理的可靠方法。金融危机爆发近十年来,金融技术的进步,如机器人顾问、数据和可视化分析的使用,彻底改变了散户投资者做出金融决策的方式,也改变了这些投资者的风险管理方式。本研究通过对该主题的最新和过去的研究进行系统和详尽的文献综述,定性地分析了分析和机器人咨询在确定散户投资者财务决策和风险管理方面的使用。

Disaster is the sudden problem of the world. There is no time bound. By disaster, all the creatures of the earth are affected. Here, the authors have tried to show some issues which are related to the natural calamities and green transportation. The main investigation of the paper is to describe about humanitarian supply chain management with optimized transportation cost, time, and carbon emission. Here a real-life problem of flood affected area has been chosen. When such disasters happen, quick response can reduce the devastation and save lives, and thus, it requires fulfilling the basic humanitarian needs of the affected population. In such case, organizations should also maintain the emission of the vehicles in safe range to mitigate the further disaster by pollution. A multi-objective solid transportation problem considering cost, time, and emission has been presented here. To solve the problem, this paper has used goal programming method and pareto optimal solution method. A comparison of results is also shown later. Some managerial insights are drawn to describe the situation.
灾难是世界上突如其来的问题。没有时间限制。地球上所有的生物都受到灾难的影响。在这里,作者试图展示一些与自然灾害和绿色交通有关的问题。本文的主要研究内容是描述具有优化运输成本、时间和碳排放的人道主义供应链管理。这里选择了一个受洪水影响地区的现实问题。当这种灾难发生时,快速反应可以减少破坏并拯救生命,因此,它需要满足受灾人口的基本人道主义需求。在这种情况下,组织还应将车辆的排放量保持在安全范围内,以减轻污染造成的进一步灾难。本文提出了一个考虑成本、时间和排放的多目标固体运输问题。为了解决这一问题,本文采用了目标规划法和帕累托最优解法。结果的比较也在后面显示。一些管理见解被用来描述这种情况。
