As part of management's role to respond to threats in the banking industry, the capabilities of information technology are leveraged to devise technology-driven offensive strategies. Participants of the study were drawn from eight universal banks in Ghana. The relationships that exist among managerial roles, managerial roles and participants, and how participants are related were examined. The systematic procedure of grounded theory design and subsequent analysis of the generated frequencies using a quantitative technique of correspondence analysis were followed. The obtained results of p-value = 0.000 indicates a strong dependency in the data. The inertia >.5 indicates strong associations among the categories and participants. The two-dimensional solution obtained accounted for 96.2% of total inertia. Findings of the study show that, the success of leading an information systems (IS)-technological innovation offensive-strategy depends on strong innovation capabilities developed through collaboration between business managers and IS/IT heads.

This study investigates the factors influencing customer satisfaction with references to on-demand home services, an emerging phenomenon in India. The hypothesized conceptual framework is grounded in the E-SQ and SERVQUAL model. To test the research hypotheses, 382 sample respondents were surveyed using a pre-tested questionnaire. The empirical validation of the proposed framework was performed with the help of PLS-SEM. The results suggest that e-service quality (E-SQ) and service quality (SERVQUAL) contribute to the overall service quality (OSQ) which has a positive influence on customer satisfaction (CS). It is further noted that, with reference to on-demand home services, overall service quality (OSQ) and customer satisfaction (CS) is moderated by value (VL). Further research could investigate the influence of OSQ on other relational constructs such as trust and customer loyalty. This study offers interesting insights to the managers and marketers in the service industry while crafting marketing strategies.

Over the past decades, numerous experts have been investigated the correlation among distinct personality traits and job performance. However, relatively less attention was paid examining the significance of technological tools in sales management, especially in developing countries. This article explores the relationship among the five-factor model (FFM) of personality traits and sales performance (SP) with a moderating role of the technology. To this end, structural equation modeling and Fisher's Z transformation analysis were employed to analyze the hypotheses. The findings revealed that extraversion, conscientiousness, openness to experience, and emotional stability traits are positively correlated to SP. In contrast, agreeableness is not highly correlated with SP relatively than the remainder traits. Additionally, results revealed the significant effect of technology as a moderator which strengthens the association of FFM and SP. This study proposes diverse managerial implications and future directions for practitioners and academicians across the nations.
在过去的几十年里,许多专家研究了不同的性格特征和工作表现之间的关系。但是,审查技术工具在销售管理方面的意义,特别是在发展中国家,所受到的注意相对较少。本文探讨了人格特质五因素模型(FFM)与销售绩效之间的关系,并在技术的调节作用下进行了研究。为此,采用结构方程建模和Fisher’s Z变换分析对假设进行分析。结果表明,外向性、尽责性、经验开放性和情绪稳定性与SP呈正相关,而亲和性与SP的相关性不高。此外,研究结果还揭示了技术作为调节因子的显著作用,增强了FFM和SP之间的联系。本研究为各国的从业者和学者提出了不同的管理启示和未来的发展方向。

Nowadays, improvement of governance, ensuring security and timely detection of propaganda against the government are major problems of e-government. The extraction of hidden social networks operating against the state in e-government is one of the key factors to ensure the security in e-government. In this article, a method has been proposed for extracting hidden social networks to improve e-government management, prevent promotion against the government and ensure the security. In this approach, hidden social networks are extracted through the analysis of user's comments via opinion and text mining technologies. The authors assume that all comments are written in one language. Unlike previous methods, to detect social relationships between actors, content analysis technology, namely opinion mining technology was used in the proposed approach.

Personalized Hybrid Book Recommender 个性化混合图书推荐
Pub Date : 2019-07-01 DOI: 10.4018/IJISSS.2019070105
Hossein Arabi, Vimala Balakrishnan
Personalized Recommendation Systems (RS) provide end users with suggestions about items that are likely to be of their interest based on users' details such as demographics, location, time, and emotion. In this article, a Personalized Hybrid Book Recommender (PHyBR) is presented, which integrates personality traits with users' demographic data and geographical location to improve the quality of recommendations. The Ten Item Personality Inventory (TIPI) was used to determine users' personality traits. PHyBR was evaluated using two metrics, that are, Standardized Root Mean Square Residual (SRMR) and Root Mean Square Error of Approximation (RMSEA). Both metrics revealed PHyBR outperforms the baseline models (without considering personality traits and geographical location factor) in terms of the recommendation accuracies. This study shows that users who are in the same geographical contexts intend to have similar preferences. Therefore, users' personality details along with their geographical locations can be used to provide improved personalized recommendations.
个性化推荐系统(RS)根据用户的详细信息,如人口统计、地点、时间和情感,为最终用户提供他们可能感兴趣的项目建议。本文提出了一种个性化混合图书推荐系统(PHyBR),该系统将用户的个性特征与用户的人口统计数据和地理位置相结合,以提高推荐的质量。使用十项人格量表(TIPI)来确定用户的人格特征。PHyBR采用标准化均方根残差(SRMR)和均方根近似误差(RMSEA)两个指标进行评估。两个指标都表明,在推荐准确性方面,PHyBR优于基线模型(不考虑人格特征和地理位置因素)。这项研究表明,处于相同地理环境的用户倾向于有相似的偏好。因此,用户的个性细节以及他们的地理位置可以用来提供改进的个性化推荐。

The Greek taxation information system is now in the second decade of its operation. Although many weaknesses were recorded in the first decade, it has been operating sufficiently well during the last five years. One critical factor for the satisfactory performance for each information system is the acceptance by its users. The purpose of this study is to investigate the parameters affecting the positive or negative intentions in the use of information systems by tax office employees, as well as their contribution to the transactions between the public and private sectors and their effects. This article focuses on three important factors: (1) those that affect the acceptance of e-government systems by employees, (2) those that affect employees' intention to accept the e-government services, and (3) the contribution of information systems to electronic transactions their effects. In particular, research is done to identify the parameters that affect the intentions for using TAXIS platform by tax office employees of four branches in the Region of Eastern Macedonia and Thrace.
希腊税收信息系统目前已进入其运作的第二个十年。虽然在第一个十年中记录了许多弱点,但它在过去五年中运作得相当好。每一个信息系统的令人满意的性能的一个关键因素是其用户的接受。本研究的目的是调查影响税务人员使用信息系统的积极或消极意图的参数,以及他们对公共和私营部门之间交易的贡献及其影响。本文重点研究了三个重要因素:(1)影响员工接受电子政务系统的因素;(2)影响员工接受电子政务服务意愿的因素;(3)信息系统对电子交易的贡献及其影响。特别地,我们进行了研究,以确定影响东马其顿和色雷斯地区四个分支机构的税务局员工使用TAXIS平台的意向的参数。

Nowadays, emergency department services are confronted to an increasing demand. This situation causes emergency department overcrowding which often increases the length of stay of patients and leads to strain situations. To overcome this issue, emergency department managers must predict the length of stay. In this work, the researchers propose to use machine learning techniques to set up a methodology that supports the management of emergency departments (EDs). The target of this work is to predict the length of stay of patients in the ED in order to prevent strain situations. The experiments were carried out on a real database collected from the pediatric emergency department (PED) in Lille regional hospital center, France. Different machine learning techniques have been used to build the best prediction models. The results seem better with Naive Bayes, C4.5 and SVM methods. In addition, the models based on a subset of attributes proved to be more efficient than models based on the set of attributes.
目前,急诊科服务面临着日益增长的需求。这种情况导致急诊科人满为患,往往增加病人的住院时间,导致紧张的情况。为了克服这个问题,急诊科经理必须预测病人的住院时间。在这项工作中,研究人员建议使用机器学习技术来建立一种支持急诊科管理的方法。这项工作的目标是预测病人在急诊科的停留时间,以防止紧张情况。实验是在法国里尔地区医院中心儿科急诊科(PED)收集的真实数据库上进行的。不同的机器学习技术被用来建立最好的预测模型。使用朴素贝叶斯、C4.5和支持向量机的结果更好。此外,基于属性子集的模型被证明比基于属性集的模型更有效。

Risk is an integrated part of the banking functions, which cannot be eliminated completely but it can be reduced by employing appropriate techniques. Credit processing is one of the core functions in the banking system, and its performance is closely related to management of the risks. The aim of this article is to develop a credit scorecard model which can be used as decision support system. A logistic regression with stepwise selection method is used to estimate the model parameters. The data that is used to construct the credit scorecard model is obtained from one of the pioneering banks in Turkish Banking Sector. The performance of the developed model is tested using statistical metrics including Receiver Operator Characteristic (ROC) curve and Gini statistics. The result reveals that the model performs well and it can be used as a decision support system for managing the credit risk by managers of the banks.

The data that is used to construct the credit scorecard model is obtained from one of the pioneering banks in Turkish Banking Sector. The performance of the developed model is tested using statistical metrics including Receiver Operator Characteristic (ROC) curve and Gini statistics. The result reveals that the model performs well and it can be used as a decision support system for managing the credit risk by managers of the banks.","PeriodicalId":151306,"journal":{"name":"Int.

Object and human tracking in streaming videos are one of the most challenging problems in vision computing. In this article, we review some relevant machine learning algorithms and techniques for human identification and tracking in videos. We provide details on metrics and methods used in the computer vision literature for monitoring and propose a state-space representation of the object tracking problem. A proof of concept implementation of the state-space based object tracking using particle filters is presented as well. The proposed approach enables tracking objects/humans in a video, including foreground/background separation for object movement detection.
流媒体视频中的物体和人的跟踪是视觉计算中最具挑战性的问题之一。在本文中,我们回顾了一些相关的机器学习算法和技术,用于视频中的人类识别和跟踪。我们详细介绍了计算机视觉文献中用于监控的度量和方法,并提出了对象跟踪问题的状态空间表示。最后给出了一种基于状态空间的粒子滤波目标跟踪的概念验证。所提出的方法能够跟踪视频中的物体/人,包括用于物体运动检测的前景/背景分离。
