Many firms find it challenging to develop innovations, evidenced by the ever-mounting number of university-industry research alliances. This study examines the strategic choices of actors who participate in collaborative innovation alliances involving partnerships between industry and universities (U-I) based on a stochastic evolutionary game model. White noise was introduced to reflect uncertainty and the stochastic interferences caused by the differences between actors. Using the Itô stochastic differential equation theory, we analyze stability issues of player behaviors in the evolution of a collaborative innovation alliance. The results illustrate that improvements in innovation efficiency can contribute to U-I collaborative innovation alliances. High knowledge complementarity appears to be unbeneficial to the stability of these alliances, and controlling knowledge spillovers may suppress free-rider problems from both sides of the game. Our study contributes to innovation research by providing a decision-making reference for the design of U-I cooperation.
许多公司发现开发创新具有挑战性,不断增加的大学-工业研究联盟证明了这一点。基于随机进化博弈模型,研究了产学研合作创新联盟(U-I)的战略选择。引入白噪声来反映不确定性和参与者之间差异引起的随机干扰。运用Itô随机微分方程理论,分析了协同创新联盟演化过程中参与者行为的稳定性问题。研究结果表明,创新效率的提高有助于U-I协同创新联盟的发展。知识的高度互补性不利于联盟的稳定,控制知识溢出可以抑制博弈双方的搭便车问题。本研究为U-I合作的设计提供决策参考,有助于创新研究。

The creation of value is a critical factor that determines the competitive capacity of firms and their ability to survive. Notwithstanding its importance, value creation usually becomes a fuzzy concept that is difficult to grasp, especially when increasingly complex elements of reality are incorporated into its analysis. Building on the narrative of the firm as a complex adaptive system, this article provides empirical evidence showing value creation as emergent behavior resulting from hyper-connected value repositories. Several implications for scholars and practitioners are discussed. For scholars, expert knowledge is provided from 28 airline industry executives around the world together with a method based on fuzzy cognitive maps that allows modeling and simulating value creation in airlines through 26 value repositories and 77 interdependencies. For practitioners, the article raises awareness of the need to incorporate a complexity mindset into value creation analysis and smooths the transition towards a value performance management tool.
价值的创造是决定企业竞争能力和生存能力的关键因素。尽管价值创造很重要,但它通常成为一个难以把握的模糊概念,特别是当现实中日益复杂的因素被纳入其分析时。基于公司作为一个复杂的适应系统的叙述,本文提供了经验证据,表明价值创造是由超连接的价值存储库产生的紧急行为。讨论了对学者和实践者的几点启示。对于学者来说,来自全球28位航空业高管的专家知识,以及基于模糊认知地图的方法,可以通过26个价值存储库和77个相互依赖关系来建模和模拟航空公司的价值创造。对于实践者来说,这篇文章提高了对将复杂性思维模式合并到价值创造分析中的必要性的认识,并使向价值绩效管理工具的过渡更加顺利。

It is aimed to identify the basic success factors, which are essential for startups as they intend to develop successful and profitable business models over time. To this end, it is attempted to analyze the sentiments on user-generated content (UGC) on Twitter. First, trigram word cloud is used. Then, a sentiment analysis is done with various predictive models including random forest, support-vector machine (SVM) and multilayer perceptron (MLP) to test the labeling of unlabeled data. To divide topics into negative, positive, and neutral sentiments, latent Dirichlet allocation (LDA) has been applied. According to the results, the MLP method on the basis of accuracy criterion offers an accuracy of 0.81, which is higher than other tested methods. In this regard, random forest and SVM methods provide accuracy of 0.78 and 0.80, respectively. Voting and stacking algorithms were used to increase the accuracy of the algorithms. However, it is found that with the use of voting method, the accuracy is almost equal to the results obtained from the MLP and with stacking method the accuracy is less than all three methods. Using word cloud, it is indicated that the most negative trigram is startups innovation regarding climate change, the most positive one is product marketing management and business-related concepts are determined as neutral. It is found that startup acceleration process, pushing for quicker completion, delivering the best product at the beginning of the project, poor management practices, and focusing just on properties are grouped as negative sentiments. On the other hand, sustainable and innovative business plan, the presence of experienced entrepreneurs and investors, coronavirus (COVID-19), and innovation are recognized as positive sentiments, and no analysis is given for neutral sentiments.
它旨在确定基本的成功因素,这些因素对于初创公司来说是必不可少的,因为他们打算随着时间的推移开发成功和盈利的商业模式。为此,本文试图分析Twitter上用户生成内容(UGC)的情绪。首先,使用三元词云。然后,使用随机森林、支持向量机(SVM)和多层感知器(MLP)等多种预测模型进行情感分析,以测试未标记数据的标记。为了将主题划分为消极、积极和中性情绪,应用了潜在狄利克雷分配(LDA)。结果表明,基于精度准则的MLP方法的精度为0.81,高于其他测试方法。在这方面,随机森林和支持向量机方法的准确率分别为0.78和0.80。为了提高算法的准确性,采用了投票和叠加算法。然而,我们发现,使用投票法得到的结果与使用MLP得到的结果几乎相等,而使用堆叠法得到的结果精度低于这三种方法。利用词云分析发现,最负面的三元组是创业公司在气候变化方面的创新,最积极的三元组是产品营销管理,与商业相关的概念被确定为中性。研究发现,启动加速过程、推动更快的完成、在项目开始时交付最好的产品、糟糕的管理实践以及只关注属性都被归为负面情绪。相反,持续创新的企业计划、有经验的企业家和投资者的存在、新冠病毒(COVID-19)、创新被认为是积极情绪,而中性情绪没有被分析。

Leadership is considered to be a viable solution to avoid persistent project failures in an increasingly volatile and uncertain competitive business environment; however, practitioners and researchers have yet to reach a consensus on the best leadership style to prevent project failure. Although past studies have examined different leadership models in the project environment, they have overlooked the importance of emerging leadership styles in managing new business realities. This article thus attempts to determine whether two leadership styles, that is, contingent reward and empowering, directly and indirectly achieve project success. Data were collected from 289 project team members in the IT sector and analysed using partial least squares structural equation modelling. The results demonstrate the positive impact of empowering leadership on employee self-leadership, which leads to project success. Further, employee self-leadership positively mediates the link between empowering leadership and project success, while goal clarity moderates the influence of self-leadership on project success. However, contingent reward leadership neither directly nor indirectly (through self-leadership) showed any significant relationship with project success.
领导被认为是一个可行的解决方案,以避免在日益动荡和不确定的竞争商业环境中持续的项目失败;然而,实践者和研究者还没有就防止项目失败的最佳领导风格达成共识。尽管过去的研究考察了项目环境中的不同领导模式,但它们忽视了新兴领导风格在管理新业务现实中的重要性。因此,本文试图确定两种领导风格,即偶然奖励和授权,是否直接或间接地实现了项目的成功。从IT部门的289名项目团队成员收集数据,并使用偏最小二乘结构方程模型进行分析。结果表明,授权型领导对员工自我领导有积极影响,从而导致项目成功。此外,员工自我领导正向调节授权型领导与项目成功之间的关系,而目标清晰性调节自我领导对项目成功的影响。然而,偶然奖励领导既不直接也不间接(通过自我领导)显示出与项目成功的显著关系。

Wi-Fi technology is one of the most electronic services that recently emerged in the banking sector that provides significant benefits to clients and banks. Thus, the study aims to validate the factors influencing the adoption of Wi-Fi (Near Field Communication) technology by banking sector clients using an extended technology acceptance model. One hundred sixty-two valid surveys were gained from Jordanian clients via an online survey. Data were analyzed using the PLS-SEM technique. Perceived usefulness, perceived ease of use, and perceived bank credibility all have a significant effect on the adoption of Wi-Fi technology services. However, perceived awareness, reference groups, and security concerns have no significant effect on the adoption of Wi-Fi technology services. The research has several implications for theory and practice. It also makes several suggestions for future studies and points out some limitations.

We explore the open innovation research model in order to remove barriers in service organizations, where lack of knowledge is the main barrier to innovation. The purpose of this paper is to propose a research model exploring the relationship between open innovation, organizational learning ability, absorptive capacity, and strategic innovation. In this study, we collected data from 330 pharmaceutical companies in Lahore and Karachi (Pakistan). The Structural equation model analysis was used through analysis of moment structures and statistical package for the social sciences to check the relationship between the variables. The results reveal that hypotheses related to innovation have been accepted. The findings of this study are evidence that various types of open innovation have different effects on strategic innovation. The inbound and outbound open innovation directly affects strategic innovation; the mutual effect of exploitative learning ability and explorative learning ability between open innovation and strategic innovation have indirect effects. Similarly, the empirical findings of absorptive capacity also significantly impact open innovation and organizational learning ability. This study contributes to the theory by introducing exploitative and explorative learning abilities as mediators between open innovation and strategic innovation. Moreover, it analyzes how absorptive capacity may enhance learning abilities through the open innovation phenomenon. Practically, this study would help the managers understand and improve organizational productivity and gain competitive advantage by creating, sharing, and utilizing knowledge through internal and external avenues.
我们探索开放式创新研究模式是为了消除服务组织中知识缺乏是创新的主要障碍。本文的目的是提出一个探索开放式创新、组织学习能力、吸收能力和战略创新之间关系的研究模型。在这项研究中,我们收集了来自拉合尔和卡拉奇(巴基斯坦)330家制药公司的数据。采用结构方程模型分析,通过对弯矩结构的分析和对社会科学的统计包来检验变量之间的关系。结果表明,与创新相关的假设已被接受。研究结果表明,不同类型的开放式创新对战略创新有不同的影响。对内开放型创新和对外开放型创新直接影响战略创新;开放性创新和战略性创新之间的利用性学习能力和探索性学习能力的相互作用具有间接效应。同样,吸收能力对开放式创新和组织学习能力也有显著影响。本研究通过引入利用性和探索性学习能力作为开放式创新和战略创新之间的中介,为理论提供了贡献。此外,本文还分析了吸收能力如何通过开放式创新现象增强学习能力。在实践中,本研究将帮助管理者通过内部和外部的途径创造、分享和利用知识,从而了解和提高组织的生产力,从而获得竞争优势。

Among Renewable Energy Sources wind and solar energy are the most prominent and favorable substitutes to meet mankind’s future electricity requirements. Typically, these resources are combined in a distribution network to provide local distribution users. The amalgamation of these upgrades into the distribution network may modify the malfunction and network topologies, which may fail due to their pre-set state. Therefore, an advanced and accurate tracking device must continuously monitor topology changes, which is the Phasor Measuring Unit (PMU). This work proposes a new technique based on the Sea Lion Optimization Algorithm to determine the Optimal PMU Placements and its employment positions, i.e. the power structure is completely perceptible. In addition, the cost of system losses can be calculated with or without wind energy to achieve energy reserves. The energy losses before and after the wind turbine connection is compared to realize energy reserves. This comparison of energy reserves is made using Realistic and Stochastic platforms. Comparison and proposed formulas offered in the IEEE 15, 33, 69, and 85 bus distribution networks were explored to prove their effectiveness. Moreover, the proposed methodology produces more trusted results than those of other methods in the literature.
在可再生能源中,风能和太阳能是满足人类未来电力需求的最突出和有利的替代品。通常,这些资源组合在一个分配网络中,以提供本地分配用户。这些升级合并到配电网中可能会改变故障和网络拓扑结构,这些故障和网络拓扑结构可能由于其预设状态而失败。因此,需要一种先进、准确的跟踪装置来连续监测拓扑变化,这就是相量测量单元(PMU)。本文提出了一种基于海狮优化算法确定PMU最优放置位置及其就业位置的新技术,即权力结构完全可感知。此外,还可以通过计算有无风能的系统损耗成本来实现能源储备。对比风电机组连接前后的能量损失,实现能量储备。这种能源储备的比较是使用现实和随机平台进行的。对IEEE 15、33、69和85总线配电网中提供的公式进行了比较和建议,以证明它们的有效性。此外,所提出的方法比文献中其他方法产生更可信的结果。

A core region captioning framework for automatic video understanding in story video contents 故事视频内容自动理解的核心区域字幕框架

Due to the rapid increase in images and image data, research examining the visual analysis of such unstructured data has recently come to be actively conducted. One of the representative image caption models the DenseCap model extracts various regions in an image and generates region-level captions. However, since the existing DenseCap model does not consider priority for region captions, it is difficult to identify relatively significant region captions that best describe the image. There has also been a lack of research into captioning focusing on the core areas for story content, such as images in movies and dramas. In this study, we propose a new image captioning framework based on DenseCap that aims to promote the understanding of movies in particular. In addition, we design and implement a module for identifying characters so that the character information can be used in caption detection and caption improvement in core areas. We also propose a core area caption detection algorithm that considers the variables affecting the area caption importance. Finally, a performance evaluation is conducted to determine the accuracy of the character identification module, and the effectiveness of the proposed algorithm is demonstrated by visually comparing it with the existing DenseCap model.
由于图像和图像数据的快速增长,对这类非结构化数据进行可视化分析的研究最近得到了积极的开展。其中一种代表性的图像标题模型是DenseCap模型,该模型提取图像中的各个区域并生成区域级标题。然而,由于现有的DenseCap模型没有考虑区域标题的优先级,因此很难识别出最能描述图像的相对重要的区域标题。对于故事内容的核心领域,如电影和电视剧中的图像,也缺乏对字幕的研究。在这项研究中,我们提出了一个新的基于DenseCap的图像字幕框架,旨在促进对电影的理解。此外,我们设计并实现了字符识别模块,将字符信息用于核心区域的字幕检测和字幕改进。我们还提出了一种考虑影响区域标题重要性的变量的核心区域标题检测算法。最后,通过性能评估来确定字符识别模块的准确性,并通过与现有的DenseCap模型进行视觉对比来验证所提算法的有效性。

One of the representative image caption models the DenseCap model extracts various regions in an image and generates region-level captions. However, since the existing DenseCap model does not consider priority for region captions, it is difficult to identify relatively significant region captions that best describe the image. There has also been a lack of research into captioning focusing on the core areas for story content, such as images in movies and dramas. In this study, we propose a new image captioning framework based on DenseCap that aims to promote the understanding of movies in particular. In addition, we design and implement a module for identifying characters so that the character information can be used in caption detection and caption improvement in core areas.

This research examines the problems encountered by the Training Needs Assessment (TNA) system from the perspective of faculty members and Human Resources (HR) managers in emerging public universities in the Saudi Arabian Higher Education sector. It aims to understand how problems with this will affect the success rate of Training and Development (T&D) curriculums. The research comprises an analytical study using a case study method of analysis. Qualitative data collection was carried out using semi-structured interviews with 75 senior managers and faculty members of four selected universities, selected using purposive non-random sampling. The data was analysed using Thematic Analysis (TA). The results highlight the insufficiency of the TNA techniques applied to ascertain training requirements. The primary obstacles to successful TNA were inadequate HR processes, insufficiently experienced HR directors, poor engagement, and favouritism concerning the selection of candidates for T&D. These issues affect the enthusiasm of those in the department. Additionally, resources required for T&D, particularly time and money, are misused, which could influence the growth potential of the universities against the country’s Vision 2030 plan. The findings indicate procedural differences in selecting and approving staff requests for Human Resource Development (HRD) support, managerial discretion in selecting participants for HRD programmes, and selective or restricted access to HRD programmes for foreign-born employees, which raises significant questions about equality policies. This study is unique as a contribution to the literature in exploring the challenges faced by the TNA process in Saudi Arabian Higher Education, therefore broadening understanding in the field as a whole, especially concerning the developing countries and Gulf Cooperation Council of Nations. The study concludes that there is currently unsatisfactory commitment in determining the staff training needs by the HR departments of Saudi Arabian public universities, which damages morale and leads to a lack of faith between HR directors and departmental staff. Finally, this study contributes to the area of policy decision-making by reporting the present situation surrounding the issues related to the application of TNA in T&D.
本研究从沙特阿拉伯高等教育部门新兴公立大学的教师和人力资源(HR)管理人员的角度考察了培训需求评估(TNA)系统遇到的问题。它旨在了解这些问题将如何影响培训与发展(T&D)课程的成功率。本研究采用个案分析方法进行分析性研究。定性数据收集采用半结构化访谈,对四所大学的75名高级管理人员和教职员工进行访谈,选择采用有目的的非随机抽样。数据采用主题分析法(Thematic Analysis, TA)进行分析。结果突出表明用于确定培训需求的TNA技术的不足。TNA成功的主要障碍是人力资源流程不足、经验不足的人力资源主管、参与度低以及在选择T&D候选人方面的偏袒。这些问题影响了部门人员的积极性。此外,技术与发展所需的资源,特别是时间和金钱,被滥用,这可能会影响大学的增长潜力,不利于国家的2030年愿景计划。调查结果表明,在选择和批准工作人员要求人力资源开发支助方面存在程序上的差异,在选择人力资源开发方案参与者方面存在管理上的自由裁量权,以及外国出生雇员有选择性地或有限制地参加人力资源开发方案,这些都提出了关于平等政策的重大问题。这项研究的独特之处在于,它对探索沙特阿拉伯高等教育中TNA进程所面临的挑战的文献做出了贡献,从而拓宽了对整个领域的理解,特别是对发展中国家和海湾国家合作委员会的理解。研究得出结论,目前沙特阿拉伯公立大学人力资源部门在确定员工培训需求方面的承诺并不令人满意,这损害了士气,导致人力资源主管和部门员工之间缺乏信任。最后,本研究通过报告TNA在T&D中应用的相关问题的现状,为政策决策领域做出贡献。
