PurposeSex and age estimation is important, particularly when information about the deceased is unavailable. There are limited radiological studies investigating side, sex and age differences in normal ankle morphometric parameters. The authors’ goal was to evaluate different ankle joint morphometric measurements and document variations among Egyptians.Design/methodology/approachA prospective study was conducted throughout 23 months on 203 (100 males and 103 females) adult Egyptians, aged between 20-69 years old, who were referred for a plain x-ray of bilateral normal ankle joints.FindingsAnkle parameters showed no statistical difference between both sides, except for tarsal width (TaW) which was significantly higher on right than left side (26.92 ± 2.66 vs 26.18 ± 2.65 mm). Males showed significantly higher morphometric values except for anteroposterior gap (APG) and talus height (TaH) which were significantly higher in females (2.29 ± 0.80 vs 1.80 ± 0.61 mm and 13.01 ± 1.68 vs 11.87 ± 1.91 mm, respectively). There was significant increase in tibial arc length, APG, distance of level of MTiTh from anterior limit of mortise, distance of level of MTiTh from vertex of mortise, sagittal distance between tibial and talar vertices and sagittal radius of trochlea tali arc in old age group compared to young one. A significant decrease in tibial width, malleolar width, TaW and TaH was noted in old age group compared to young one.Originality/valueAnkle joints of both sides are mostly symmetrical; however, there are significant differences in most morphometric values due to sex and age factors. These findings may be essential during side, sex and age determination.
目的:性别和年龄的估计是很重要的,特别是在无法获得死者信息的情况下。有有限的放射学研究调查侧面,性别和年龄在正常踝关节形态测量参数的差异。作者的目标是评估不同的踝关节形态测量和埃及人之间的文件差异。设计/方法/方法对203名(100名男性和103名女性)年龄在20-69岁之间的埃及成年人进行了为期23个月的前瞻性研究,他们接受了双侧正常踝关节的x线平片检查。除跗宽度(TaW)右侧明显高于左侧(26.92±2.66 mm vs 26.18±2.65 mm)外,两组间踝关节参数差异无统计学意义。除距骨高度(TaH)和前后间隙(APG)(2.29±0.80 vs 1.80±0.61 mm)和距骨高度(13.01±1.68 vs 11.87±1.91 mm)显著高于雌性外,雄性的形态测量值显著高于雌性。老年组胫骨弧长、APG、距榫前极限的MTiTh水平距离、距榫顶点的MTiTh水平距离、胫骨距距顶点的矢状距离、滑车弧矢状半径均显著高于青年组。老年组胫骨宽度、踝宽度、TaW、TaH均较年轻组明显减小。创意/价值两侧踝关节多对称;然而,由于性别和年龄因素,大多数形态测量值存在显著差异。这些发现在侧面、性别和年龄的确定中可能是必要的。

PurposeCesspits are the means for each house to dispose of wastewater in the Bani Kinanah District (BKD) of Jordan, which creates severe environmental complications. This research aimed to find a suitable site for a wastewater treatment plant (WWTP) in BKD.Design/methodology/approachGeographic Information System (GIS)-based multicriteria decision analysis (MCDA) was used for an optimal site selection for a sewage treatment plant. Several datasets were obtained to prepare the maps of the criteria influencing the choice of the most suitable site for the WWTP. The analytic hierarchy process was used to apply the weights for each factor.FindingsFive classes of suitability were generated: 0.23% very high suitability, 8.49% high suitability, 47.12% moderate suitability, 37.67% low suitability and 6.49% very low suitability. According to Analytical Hierarchy Process (AHP) results, the elevations, slope and groundwater depth have high importance; where their weights 21%, 19% and 17%, respectively. The most suitable site for establishing a WWTP was found in the northern part of the study area, where it is characterized by relatively low elevations (−90 to −93 m), low slope (0–2.5 %), distance from groundwater level (47–82 m) and the space is sufficient for building the plant (25328 m2, 8861 m2 and 8586 m2).Research limitations/implicationsThis research is limited by the availability of data.Practical implicationsThe research is invaluable for decision makers involved in urban planning.Social implicationsWastewater treatment plants are essential for communities with limited resources such as Jordan. It has also profound impacts on the surrounding environment.Originality/valueFrom the present study, it can be concluded that GIS is essential in urban utility establishment, like urban domestic wastewater treatment site selection. Although the study area has adequate potential areas for establishing WWTP, further assessment of flood vulnerability, wastewater amount quantification, population growth and urban expansion must be seriously considered before implementation.
目的在约旦巴尼基纳赫区(Bani Kinanah District,BKD),污水坑是每家每户处理废水的方式,这造成了严重的环境问题。本研究旨在为 Bani Kinanah 区的污水处理厂(WWTP)寻找合适的选址。设计/方法/途径基于地理信息系统(GIS)的多标准决策分析(MCDA)被用于污水处理厂的最佳选址。通过获取多个数据集,绘制了影响污水处理厂最合适选址的标准图。采用层次分析法对每个因素进行加权:0.23% 非常适合、8.49% 高适合、47.12% 中等适合、37.67% 低适合和 6.49% 非常低适合。根据层次分析法(AHP)的结果,海拔、坡度和地下水深度具有较高的重要性,其权重分别为 21%、19% 和 17%。最适合建立污水处理厂的地点位于研究区域的北部,其特点是海拔相对较低(-90 至 -93 米)、坡度较小(0-2.5%)、距离地下水位较远(47 至 82 米),并且有足够的空间(25328 平方米、8861 平方米和 8586 平方米)来建设污水处理厂。社会影响对于约旦这样资源有限的社区来说,污水处理厂是必不可少的。原创性/价值从本研究中可以得出结论,地理信息系统在城市公用设施建设中至关重要,如城市生活污水处理选址。虽然研究区域有足够的潜在区域用于建立污水处理厂,但在实施之前必须认真考虑对洪水脆弱性、废水量量化、人口增长和城市扩张的进一步评估。

Purpose Using a combination of the geographical information system (GIS) and the Canadian water quality index (WQI), the current study sought to provide a long-term general assessment of the water quality of the Shatt Al-Arab River (SAAR), focusing on its suitability for living organisms. Likewise, SPSS statistics was used to develop a nonlinear WQI regression model for the study area. Design/methodology/approach The study required four decades of data collection on some environmental characteristics of river water. After that, calculate the WQI and conduct the spatial analysis. Eight variables in total, including water temperature, dissolved oxygen, potential hydrogen ions, electrical conductivity (EC), biological oxygen demand, turbidity, nitrate and phosphate, were chosen to calculate the WQI. Findings Throughout the study periods, the WQI values varied from 55.2 to 79.83, falling into the categories of four (marginal) and three (fair), with the sixth period (2007–2008) showing the most decline. The present research demonstrated that the high concentration of phosphates, the high EC values, and minor changes in the other environmental factors are the major causes of the decline in water quality. The variations in ecological variables' overlap are a senior contributor to changes in water quality in general. Notably, using GIS in conjunction with the WQI has shown to be very effective in reducing the time and effort spent on investigating water quality while obtaining precise findings and information at the lowest possible expense. Calibration and validation of the developed model showed that this model had a perfect estimate of the WQI value. Due to its flexibility and impartiality, this study recommends using the proposed model to estimate and predict the WQI in the study area. Originality/value Even though the water quality of the SAAR has been the subject of numerous studies, this is the only long-term investigation that has been done to evaluate and predict its water quality.
利用地理信息系统(GIS)和加拿大水质指数(WQI)的结合,本研究试图对阿拉贝河(SAAR)的水质进行长期总体评估,重点关注其对生物的适宜性。同样,采用SPSS统计方法建立了研究区域的非线性WQI回归模型。设计/方法/方法这项研究需要四十年来收集有关河水某些环境特征的数据。然后,计算WQI并进行空间分析。选取水温、溶解氧、氢离子电位、电导率(EC)、生物需氧量、浊度、硝酸盐和磷酸盐共8个变量计算WQI。在整个研究期间,WQI值在55.2 - 79.83之间变化,分为4级(边缘)和3级(一般),其中第6期(2007-2008年)下降幅度最大。目前的研究表明,高浓度的磷酸盐、高EC值以及其他环境因子的微小变化是导致水质下降的主要原因。总的来说,生态变量重叠的变化是水质变化的一个重要因素。值得注意的是,将地理信息系统与水质指数结合使用,可以非常有效地减少调查水质所花费的时间和精力,同时以尽可能低的费用获得精确的结果和信息。开发模型的校准和验证表明,该模型有一个完美的估计的水质指数的值。由于其灵活性和公正性,本研究建议使用所提出的模型来估计和预测研究区域的WQI。原创性/价值尽管南澳区的水质一直是众多研究的主题,但这是唯一一项评估和预测其水质的长期调查。

Purpose When the repercussions of COVID-19 were being absorbed by the world, the higher educational institutions (HEIs) were conceiving of strategies to run educational institutions on remote basis too, including the challenges linked with the teaching–learning as well as the management and other departmental needs. Leaning itself on the teaching–learning tectonic shifts amid the COVID-19 climes, the study reviews the status of “readiness” of the HEIs in Oman while bearing this in mind that the usage of information and communications technology (ICT) for distance learning and conventional learning has been considered as one of the parameters to judge the “quality” of the HEIs in Oman. Design/methodology/approach Documentary analysis alongside an in-depth reading of the quality audit reports sourced from the Oman Academic Accreditation Authority, which are publicly accessible are being referred for driving home the arguments in the study. Findings The study concludes that despite the case being in favor of distance learning from early on, the same doesn’t get reflected in the conclusions derived in the research conducted for assessing the teaching–learning mechanisms during the COVID-19 period. Therefore, the HEIs’ “readiness” in terms of ensuring the smooth transitioning to the remote learning pedagogical arrangements for meeting the challenges of the COVID-19 wasn’t efficacious. Research limitations/implications The present study may be followed up with an understanding as to how the HEIs of Oman need to incorporate the perspectives of all the concerned stakeholders for the refurbishment of the teaching–learning process, especially in times of contingencies. Practical implications Apart from the policy-makers, the management of the HEIs of Oman needs to appreciate the need to be proactive and appreciative of the inclusion of ICT tools and techniques in the mainstream pedagogical settings. Originality/value Notwithstanding the emphasis upon the preparedness and readiness for tackling the challenges posed by the COVID-19 for the HEIs in Oman, no study has attempted to delve into the issue succinctly—the present study fills this gap.
当世界正在吸收COVID-19的影响时,高等教育机构(HEIs)也在考虑远程管理教育机构的战略,包括与教与学以及管理和其他部门需求相关的挑战。该研究着眼于2019冠状病毒病背景下的教学结构转变,审查了阿曼高等教育机构的“准备就绪”状况,同时考虑到信息和通信技术(ICT)在远程学习和传统学习中的使用已被视为判断阿曼高等教育机构“质量”的参数之一。设计/方法/方法参考文献分析以及对来自阿曼学术认证局的质量审计报告的深入阅读,这些报告是公开的,用于推动研究中的论点。研究得出的结论是,尽管从一开始就支持远程学习,但在评估新冠肺炎期间教学机制的研究中得出的结论并未反映出这一点。因此,高校在确保顺利过渡到远程学习教学安排以应对新冠肺炎挑战方面的“准备”并不有效。研究限制/影响本研究的后续工作可能是了解阿曼的高等教育机构如何需要纳入所有有关利益攸关方的观点,以更新教学过程,特别是在紧急情况下。除政策制定者外,阿曼高等教育机构的管理层也需要认识到,需要积极主动地将信息通信技术工具和技术纳入主流教学环境。尽管强调了为应对2019冠状病毒病带来的挑战而做好的准备和准备,但没有一项研究试图简洁地深入研究这一问题——本研究填补了这一空白。

Purpose This case study paper aims to explore the complexities and challenges of epidemic response and public health surveillance in Native American and Indigenous American communities in the United States and find viable solutions. This paper explores these topics through the emergence and impact of the hantavirus pulmonary syndrome (HPS) within the Navajo Nation in the United States using critical incident analysis and best practices. Design/methodology/approach This project is a case study paper based on a topical review of the literature. A topical review of the literature is a comprehensive exploration of the current body of knowledge within a particular research field. It is an important tool used by scholars and practitioners to further the development of existing knowledge as well as to identify potential directions for future research (Fourie, 2020). Such a paper can provide a useful insight into the various aspects of the process that the researcher may have overlooked, as well as highlighting potential areas of improvement (Gall et al ., 2020). It can also provide a useful source of ideas and inspiration for the researcher as it can provide an overview of the various approaches used by other researchers in the field (Göpferich, 2009). Case study papers using a topical review of the literature have been used to help frame and inform research topics, problems and best practices for some time. They are typically used to explore a topic in greater depth and to provide an overview of the literature to improve the world of practice to provide a foundation for future comprehensive empirical research. Case study papers can provide research value by helping to identify gaps in the literature and by providing a general direction for further research. They can also be used to provide a starting point for research questions and hypotheses and to help identify potential areas of inquiry. Findings This study explores best practices in public health surveillance and epidemic response that can help strengthen public health infrastructure by informing the development of effective surveillance systems and emergency response plans, as well as improving data collection and analysis capabilities within Native American and Indigenous American communities in the United States that also have the option to include new technologies like artificial intelligence (AI) with similar outbreaks in the future. Research limitations/implications The literature review did not include any primary data collection, so the existing available research may have limited the findings. The scope of the study was limited to published literature, which may not have reported all relevant findings. For example, unpublished studies, field studies and industry reports may have provided additional insights not included in the literature review. This research has significant value based on the limited amount of studies on how infectious diseases can severely impact Native American communi
本案例研究论文旨在探讨美国土著美洲人和土著美洲人社区流行病应对和公共卫生监测的复杂性和挑战,并找到可行的解决方案。本文通过汉坦病毒肺综合征(HPS)在美国纳瓦霍民族内的出现和影响,利用关键事件分析和最佳实践,探讨了这些主题。设计/方法/方法本项目是一篇基于专题文献综述的案例研究论文。专题文献综述是对某一特定研究领域内现有知识体系的全面探索。它是学者和实践者用来进一步发展现有知识以及确定未来研究潜在方向的重要工具(Fourie, 2020)。这样的论文可以为研究人员可能忽略的过程的各个方面提供有用的见解,并突出潜在的改进领域(Gall等人,2020)。它还可以为研究人员提供有用的想法和灵感来源,因为它可以提供该领域其他研究人员使用的各种方法的概述(Göpferich, 2009)。一段时间以来,使用专题文献综述的案例研究论文被用来帮助构建和告知研究主题、问题和最佳实践。它们通常用于更深入地探索一个主题,并提供文献概述,以改善实践世界,为未来全面的实证研究提供基础。案例研究论文可以通过帮助确定文献中的空白并为进一步研究提供总体方向来提供研究价值。它们也可以用来为研究问题和假设提供起点,并帮助确定潜在的研究领域。本研究探讨了公共卫生监测和流行病应对的最佳做法,通过为制定有效的监测系统和应急响应计划提供信息,有助于加强公共卫生基础设施。以及提高美国土著美洲人和美国土著社区的数据收集和分析能力,这些社区还可以选择在未来类似疫情爆发时采用人工智能等新技术。研究局限性/启示文献综述没有包括任何原始数据收集,因此现有的可用研究可能限制了研究结果。研究范围仅限于已发表的文献,可能没有报道所有相关发现。例如,未发表的研究、实地研究和行业报告可能提供了文献综述中未包含的额外见解。鉴于关于传染病如何严重影响美国印第安人社区、导致不必要和可预防的痛苦和死亡的研究数量有限,这项研究具有重要价值。因此,需要通过历史事件和重大事件分析,研究可行的最佳做法,研究美洲土著和美洲土著社区公共卫生监测和流行病应对的最佳做法。对美洲土著社区的公共卫生监测和流行病应对的研究可以深入了解这些社区面临的挑战,并有助于确定潜在的解决方案,以提高他们使用创新方法和人工智能等新技术检测、应对和预防传染病的能力。更多关于公共卫生监测和流行病应对的研究可以为政策和干预措施提供信息,以改善美洲土著人口获得医疗保健的机会,例如增加医疗保健服务的可得性,提供文化上适当的健康教育,以及改善提供者与患者之间的沟通。通过提供更好的公共卫生监测和反应能力,研究可以帮助减轻美洲土著社区传染病的负担,并最终改善公共卫生成果。

Such a paper can provide a useful insight into the various aspects of the process that the researcher may have overlooked, as well as highlighting potential areas of improvement (Gall et al ., 2020). It can also provide a useful source of ideas and inspiration for the researcher as it can provide an overview of the various approaches used by other researchers in the field (Göpferich, 2009). Case study papers using a topical review of the literature have been used to help frame and inform research topics, problems and best practices for some time. They are typically used to explore a topic in greater depth and to provide an overview of the literature to improve the world of practice to provide a foundation for future comprehensive empirical research. Case study papers can provide research value by helping to identify gaps in the literature and by providing a general direction for further research. They can also be used to provide a starting point for research questions and hypotheses and to help identify potential areas of inquiry. Findings This study explores best practices in public health surveillance and epidemic response that can help strengthen public health infrastructure by informing the development of effective surveillance systems and emergency response plans, as well as improving data collection and analysis capabilities within Native American and Indigenous American communities in the United States that also have the option to include new technologies like artificial intelligence (AI) with similar outbreaks in the future. Research limitations/implications The literature review did not include any primary data collection, so the existing available research may have limited the findings. The scope of the study was limited to published literature, which may not have reported all relevant findings. For example, unpublished studies, field studies and industry reports may have provided additional insights not included in the literature review. This research has significant value based on the limited amount of studies on how infectious diseases can severely impact Native American communi","PeriodicalId":50978,"journal":{"name":"Arab Gulf Journal of Scientific Research","volume":"7 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135431104","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}

Purpose This study aims to measure impact of several firm-specific factors on alternative measures of leverage. The authors also aim to study impact of the subprime crisis on such associations. Design/methodology/approach The authors utilized an unbalanced panel data of 973 firm-year observations on 47 UK listed non-financial firms for the years 1990–2019. Book-based and market-based long-term and total leverage measures have been used as explained variables. The explanatory variables are profitability, size, two measures of growth, asset tangibility, non-debt tax shields, firm age and product uniqueness. Fixed effect and random effect models with clustered robust standard errors have been utilized for data analysis. To find the effect of subprime crisis, original dataset was split to create pre-crisis and post-crisis datasets. Findings The authors find that profitability significantly reduces leverage while firms having more tangible assets use significantly more debt in capital structure. Firm size and non-debt tax shield have statistically insignificant positive impact on leverage. Having more unique products reduces use of external debt, albeit insignificantly. Growth, when measured as market-to-book ratio, has inconsistent impact, whereas capital expenditure insignificantly reduces leverage. Age is found to be an insignificant predictor of leverage. After the subprime crisis, firms started relying more on internal fund instead of external debt, more particularly short-term debt. Having more collateral is gradually becoming more important for availing external debt. Research limitations/implications Data limitations restrict generalization of the findings. Originality/value This is one of the pioneering attempts to show how subprime crisis altered the theoretical domain of capital structure research in the UK.
目的本研究旨在衡量几个公司特定因素对替代杠杆措施的影响。作者还打算研究次贷危机对这些协会的影响。设计/方法/方法作者利用了对47家英国上市非金融公司1990-2019年973家公司年度观察的不平衡面板数据。基于账面和基于市场的长期和总杠杆措施已被用作解释变量。解释变量是盈利能力、规模、两个增长指标、资产有形性、非债务税盾、公司年龄和产品独特性。采用具有聚类鲁棒标准误差的固定效应和随机效应模型进行数据分析。为了找出次贷危机的影响,将原始数据集拆分为危机前和危机后的数据集。作者发现,盈利能力显著降低了杠杆率,而拥有更多有形资产的公司在资本结构中使用了更多的债务。企业规模和非债务税盾对杠杆率的正向影响不显著。拥有更多独特的产品可以减少外债的使用,尽管效果不大。当以市净率衡量时,增长的影响不一致,而资本支出对杠杆的影响则不显著。年龄是杠杆的一个不显著的预测因子。次贷危机之后,企业开始更多地依赖内部资金,而不是外部债务,尤其是短期债务。对于利用外债来说,拥有更多的抵押品正逐渐变得越来越重要。研究局限性/意义数据局限性限制了研究结果的推广。这是展示次贷危机如何改变英国资本结构研究理论领域的开创性尝试之一。

Purpose This study aimed to measure the effects of the Russian–Ukrainian war on the value of imports and the food trade balance in Saudi Arabia. Design/methodology/approach Estimating the suggested model using econometric analysis for the years 1990–2021. Findings The amount of deficit increased in the food trade balance from 11.58 billion riyals in 1990 to 72.98 billion riyals in 2021. As for the increase in the index of food production by 10%, it leads to a decrease in the value of food imports for Saudi Arabia by 1.88%. Also, the value of the deficit in Saudi Arabia's food trade balance decreases by 5.24% as a result of a 10% rise in food exports to the country. Originality/value In light of the increase in the food price index to 145.8, the value of food imports and the deficit in the food trade balance exceed their counterparts in the current situation for the year 2021, at a rate of 37.1% and 44.5% for each respectively. In view of achieving huge financial surpluses as a result of the rise in oil prices, the Saudi Arabia is able to bear the high import bill and the amount of food trade balance deficit. Finally, the Russian–Ukrainian war leads to an increase in the cost of obtaining food commodities and their unavailability in the markets and thus affects the food security environment. Therefore, this study recommends the necessity of conducting more studies on the impact of the war on the food security of the Kingdom of Saudi Arabia.
本研究旨在衡量俄罗斯-乌克兰战争对沙特阿拉伯进口价值和食品贸易平衡的影响。设计/方法/方法使用计量经济学分析对1990-2021年的建议模型进行估计。食品贸易逆差从1990年的115.8亿里亚尔增加到2021年的729.8亿里亚尔。粮食生产指数每增加10%,导致沙特阿拉伯的粮食进口价值减少1.88%。此外,由于对沙特阿拉伯的食品出口增加了10%,沙特阿拉伯食品贸易逆差的价值减少了5.24%。在粮食价格指数上升至145.8的情况下,2021年的粮食进口额和粮食贸易差额的逆差分别超过了目前情况下的37.1%和44.5%。鉴于油价上涨带来的巨额财政盈余,沙特阿拉伯有能力承担高额的进口账单和大量的粮食贸易逆差。最后,俄罗斯-乌克兰战争导致获得粮食商品的成本增加,市场上无法获得粮食商品,从而影响粮食安全环境。因此,本研究建议有必要对战争对沙特阿拉伯王国粮食安全的影响进行更多的研究。

Purpose The purpose of this paper is to analyse the determinants of financial inclusion among women-owned informal enterprises in India. Design/methodology/approach The study is based on a primary survey of 321 informal enterprises. The data has been collected through a structured questionnaire. A chi-square test has been used to examine the significant association between the characteristics of informal enterprises and their owners and financial inclusion. A logistic regression model has been developed to analyse the determinants of financial inclusion among women-owned informal enterprises. Findings A significant and negative association has been found between business duration and entrepreneurs’ experiences with financial inclusion. In addition, the chi-square test shows a significant association between resource capability, use of ICT by enterprises and financial inclusion. Further, logistics regression shows that duration of business, entrepreneurial experience, resource capability in terms of machinery and equipment use, and ICT are significant determinants of financial inclusion among women-owned informal enterprises. Practical implications There are several practical implications for national policymakers and other stakeholders, such as banks and international bodies working on financial inclusion. It is suggested that while designing the policy for financial inclusion among woman-owned informal enterprises, it should ensure that experience and older woman entrepreneurs are included in financial inclusion schemes. Originality/value There has been very few research on financial inclusion in woman-owned businesses. However, no research has been conducted on the financial inclusion of women-owned informal businesses. This study fills a gap by investigating the factors that influence financial inclusion in women-owned informal businesses.
本文的目的是分析印度妇女拥有的非正式企业中金融包容性的决定因素。本研究基于对321家非正式企业的初步调查。数据是通过结构化问卷收集的。本文采用卡方检验检验了非正规企业及其所有者特征与普惠金融之间的显著关联。已经开发了一个逻辑回归模型来分析妇女拥有的非正规企业中金融包容性的决定因素。研究发现,创业时间与企业家的普惠金融经历之间存在显著的负相关关系。此外,卡方检验显示,资源能力、企业使用ICT与普惠金融之间存在显著关联。此外,logistic回归表明,经营期限、创业经验、机器和设备使用方面的资源能力以及信息通信技术是女性拥有的非正规企业中金融包容性的重要决定因素。对国家政策制定者和其他利益相关者(如致力于普惠金融的银行和国际机构)有几个实际影响。建议在设计妇女拥有的非正规企业的普惠金融政策时,应确保将经验丰富和年龄较大的女企业家纳入普惠金融计划。关于女性拥有的企业的金融包容性的研究很少。然而,没有对妇女拥有的非正规企业的金融包容性进行研究。本研究通过调查女性拥有的非正规企业中影响普惠金融的因素,填补了这一空白。

Purpose Monocytes are a leukocytes’ subset that plays an important role in immunity. Protein kinase B (AKT) is involved in monocytes' survival, proliferation and differentiation. Using phorbol 12-myristate 13-acetate (PMA) as an inducer for cell line U937 differentiation into macrophage-like cells may be used as a model for cancer cell therapy or other biomedical research studies. The authors investigated the Akt1 signaling pathway's involvement with PMA as a differentiating agent and survival in the U937 cell line. Design/methodology/approach PMA was utilized to stimulate the differentiation of the U937 cell line into macrophage-like cells at a concentration of 10 nM. Akt1-phosphorylated Serine 473, Bad-phosphorylated Serine 136 and Caspase9-phosphorylated Serine 196 were tested by flow cytometry for the involvement of the Akt1 signaling pathway during differentiation in addition to the expression of CD14, CD206 and CD83. DNA cell cycle variation analysis was done using PI staining and cell viability and apoptosis detection using Annexin V and PI flow cytometry. Findings There was a decrease in phosphorylated Akt1 and Bad activation and an increase in Caspase9 activation, with an increase in surface markers CD14, CD206 and CD83 acquired by PMA-differentiated cells. DNA cell cycle analysis revealed cell accumulation in the G2/M phase and fewer cells in the S phase of PMA-induced U937. Apoptosis induction for Ly294002 or Wortmannin-inhibited cells and part of PMA-induced cells were detected. Originality/value These results may be used to create a model for biomedical research studies and advance the understanding of the mechanism involving differentiation of the U937 cell line.
