Google, Facebook, OpenAI, and others have released access to versions of language chatbots that they have developed. These chatbots have been trained on massive amounts of text using neural networks for language processing. Using an approach similar to security penetration testing, this paper investigates and compares three different chatbots, assessing potential strengths and limitations of these systems. The paper presents several findings, including a comparison of those systems across answers to common questions, an analysis of the use of names and activities to guide discussion in two systems, an analysis of the extent of differences in responses arising from “regeneration” of a question, the determination of a weakness in a system of knowing “who” invented something, development of a potential new subfield, sensitive topic classifiers, and an analysis of some of the implications of these findings. As part of this analysis, I find emerging topics in chatbots, such as “topic stalemate” and the use of sensitive topic classifiers.  相似文献

In this paper we present a novel conceptual model that systematizes the integrated management and adaptation of: (1) enterprise models, (2) their representations, (3) their underlying meta-models (i.e. their abstract syntax) and (4) the representation rules (i.e. concrete syntax for the respective models). All this for different modelling languages and also different versions of these languages. Thanks to our original use of the adaptive object model and type square patterns—normally applied in the context of software engineering, but here applied for enterprise engineering—we manage to provide a strong conceptual foundation for the development of software tools that allow a precise and coherent specification of models and their evolution and also of meta-models and their evolution. We also present a prototype of such a tool currently being developed to enable collaborative enterprise ontology model management using the Semantic MediaWiki as a base framework. This solution is solidly grounded on the theoretical foundations of organizational self-awareness and Ψ-theory of enterprise ontology and is a valuable contribution to facilitate general and distributed enterprise model management and also concrete and abstract syntax specification (i.e. the specification of a language's meta-model). This allows flexibility and ease of use in creation and adaptation of organizational models and also the use of semantic queries to detect and inform users on any violation of meta-model rules.

选取2010-2015年沪深A股上市公司的面板数据,借助门槛模型研究企业杠杆率与企业创新的关系。结果显示:杠杆率对企业创新有显著影响,存在既能促进创新同时降低风险的企业最优杠杆率区间,即当杠杆率处于9.3%~37.1%的范围时,杠杆率的提升能够最大地促进创新投入与创新产出,同时降低创新风险;但当前我国大部分企业并未达到增加创新产出与降低创新风险的最优均衡。同时,不同规模企业杠杆率与创新的关系具有差异性,大型企业促进创新且可规避风险的最优杠杆率的区间为杠杆率低于67.0%,中型企业为杠杆率低于22.5%,小型企业则是7.8%~17.0%的区间范围。应正确理解中央“去杠杆”政策,推进结构性去杠杆,力求在“降杠杆”和“促创新”之间达成最优平衡。  相似文献

This paper presents a case study of health service resource allocation as a basis for exploring how organizational members come to understand the meanings and implications of accounting change within the enterprise. The analysis describes how the significance of a new calculative process emerges over time, during which accounting both shapes and is in turn shaped by organizational reality. The paper concludes with a discussion of the interplay between the rhetoric and reality of accounting, reviewing the ways in which, as an expressive order, accounting provides a language for discourse, rules for guiding action and a way of establishing legitimacy in an institutionalised organization.  相似文献

Civic entrepreneurship involves engagement between the state, business and civil society to produce economic growth for the public good. In the UK context a key initiative to encourage such engagement has been the creation of local enterprise partnerships (LEPs); these structures are intended to be a key delivery driver of regional economic growth. This paper draws on insights from semi-structured interviews with actors involved in the development of a LEP in the north of England. Findings draw attention to concerns from civil society over losing its distinctiveness through these partnerships, and in the process losing its ethos as a guardian of the public good.  相似文献

This paper provides a framework for evaluating youth-led social change. The framework considers: seven topics (e.g., environment, human health and safety, and education); nine engagement types (e.g., volunteerism, research and innovation, and political engagement); six organizational types (e.g., advisory body, social enterprise, and individual); three strategies (socialization, influence, and power); and three scales of impacts (individual, community/inter-organizational, and national/international). Using this framework, empirical research provides evidence of how youth – defined as young people 15–24 years of age – have been agents of change in Canada over the 35 years from 1978 to 2012. A media content analysis of 264 articles, combined with frequency and chi-square tests, were completed to study the factors and the relationships among them. The results show a strong relationship between the impact and the strategy, topic, engagement type, and organizational type. The results also show a strong relationship between the strategy and the impact, engagement type and organizational type. The findings have implications for youth leaders and those who advocate for, work with, support, and educate them, and for those interested in evaluating social change efforts.  相似文献

The factors influencing the organizational as well as the individual decision to utilize the balanced scorecard (BSC) approach have not been widely researched. In the first part of this paper, we study BSC adoption at the organizational level while utilizing a multifaceted perspective of socio‐psychological, economic, and resource‐based influences; specifically, we investigate the perceptions of desirability, urgency, and feasibility of BSC adoption. Our findings show that customer norms, competitor norms, and organizational resources are significant predictors of BSC adoption. In the second part of the paper, we discuss individual‐level aspects of utilization decisions. Here, we explore the impact of perceived ease of use, perceived usefulness, and awareness on the intentions to use the BSC approach. Our findings show that both awareness of BSC capabilities and perceived ease of use are significantly related to perceived usefulness. However, only perceived usefulness is significantly related to intentions to use the BSC. Implications for research and practice are discussed.  相似文献

Running a social enterprise (SE) is more difficult than running a small or medium-sized enterprise because SEs have to achieve both economic sustainability as business enterprises and their social mission for the benefit of society. After a few years of operation, many SEs fail or struggle for survival. In this study, we examine some of the factors that affect an SE’s profitability, financial management, and business planning and management. Based on in-depth interviews with 22 social enterprises in Hong Kong, we find that SEs with the dual investment objectives of social mission and financial return are more sustainable and competitive than SEs with social impact as their sole objective. Furthermore, SEs managed by non-owner managers have better financial planning and performance than those managed by owner managers. In addition, SEs with an oversight/advisory committee are more competitive and have better management practices than those without such a committee. Our findings have policy implications for government, SEs, funding bodies, and non-profit organizations to enhance and promote the development of the social enterprise sector.  相似文献

In this paper, we refine and extend an earlier language design to introduce a domain-specific modeling language (DSML) for internal control modeling as an extension to an enterprise modeling method. The language is aimed at supporting the assessment of a firm's internal control system through the use of conceptual models of internal controls. In the paper, we report on the design of the modeling language, on its integration with the enterprise modeling method, present the language specification, and discuss language applications in the context of the assessment of an internal control system.  相似文献

We investigate the impact of enterprise digital transformation on the breadth of ownership and stock price volatility. Our findings demonstrate that enterprise digital transformation has enhanced the breadth of ownership. Furthermore, through cross-sectional analysis, we find that this effect is more prominent in firms with lower investor attention, greater stock underpricing, and in regions with higher levels of digitalization. Additionally, we have discovered that the increase of media coverage and investor attention serve as the underlying economic mechanism between digital transformation and ownership dispersion. Our analysis also shows that digital transformation has the potential to worsen stock price volatility. Finally, our examination of open-end mutual funds reveals a digital preference among mutual fund investors; this preference has improved fund flows while exacerbating fund volatility. Our study has practical implications for regulators and corporate managers, as they highlight the impact of digital transformation on investor decision-making.  相似文献

Applying a resource-dependency perspective to intra-multinational enterprise (MNE) power [55] and [56], this paper examines the effect of the deployment of advanced ICT and particularly the implementation of enterprise resource planning (ERP) systems. Although subsidiaries in the multinational do not have authority-based or ‘structural’ power with respect to key strategic decisions [6] and [16], they may have ‘resource-based’ power in the form of knowledge and capabilities that is of value to the multinational as a whole. Business network analysis highlights the ‘invisibility’ of the external networks (often in the host country) to the upper echelons in the multinational through which valuable subsidiary knowledge and capabilities develop. It points out that this ‘invisibility’ undermines the headquarters’ ability to control the subsidiary [3], [28], [36], [44], [70] and [74]. In this paper we argue that the deployment of ERP undermines the resource base of subsidiary power and thus helps to restore greater central authority in the MNE. The paper reports findings from studies in twelve MNEs which have implemented ERP and points out that from the perspective of subsidiary managers a key effect of ERP deployment is the reduction in their autonomy. This may have significant adverse implications for the futures of the MNE as a federative organizational form and the legitimacy of MNE operations abroad.  相似文献

本文研究国有企业民营化对企业创新的影响及其影响机制。利用中国工业企业数据库,以民营化企业为实验组、以国有企业为对照组进行双重差分检验,结果发现,国有企业民营化显著抑制了企业创新,而融资约束是抑制民营化企业创新的重要因素。进一步检验发现,融资约束对民营化企业创新的抑制作用主要存在于金融发展水平较低的地区,而在金融发展水平较高的地区,这种抑制作用并不明显。本文的研究结果从融资约束的角度拓展了民营化影响企业创新的相关研究,且从民营化的角度为金融市场如何影响企业创新提供了新的视角。此外,本文有助于澄清有关民营化的争议,为进一步深化混合所有制改革、加强金融对民营企业的支持以促进民营企业的创新和发展提供理论依据和政策参考。  相似文献

This note comments on the doubtful application of an economic concept of personal income to the non-personal business enterprise situation.
This paper presents a series of models which we believe properly reflect the relevant relationships in the lease or buy evaluation. The models present the proper cash flow variables for such an analysis and they present the impact on asset net present value of cost of capital and market risk assessment. Finally, the models reflect the simultaneous effect on asset and financial structure of the acceptance of a particular investment opportunity.  相似文献

The importance of organizational adaptation to the environment has been long recognized. A major feature of this adaptation process involves coping with environmental uncertainty. This paper reports the results of an exploratory longitudinal study which investigated the effectiveness of organizational coping in several large professional accounting firms. A significant positive relationship was observed between the reported level of organizational coping and employee performance. The implications of this finding for professional accounting firms, and organizations in the general, are discussed.  相似文献

Since removal of the peg in July 2005, China has entered a new era of a managed floating exchange rate system. Although many observers have raised concerns about the impact of such a policy change on China's trade surplus, less attention has been paid to its effects on financial markets. This paper investigates the impact of recent renminbi appreciation on stock prices in China since removal of the peg, using threshold cointegration and momentum threshold error-correction model (M-TECM). The results clearly illustrate that no short-run causal relation exists, and an asymmetric causal relationship running from the renminbi/U. S. dollar exchange rate to Chinese Shanghai A-share stock prices in the long run is based on M-TECM. Policy and the broader implications of the findings are discussed.  相似文献
