This paper aims to describe the NASD's recent proposal modifying NASD Rule 2720, the rule by which underwriting can be conducted where the underwriter and the issuer have a “conflict of interest” as defined by the rules.

Summarizes and analyzes the proposal.

On September 14, 2006, the National Association of Securities Dealers, Inc. (“NASD”) published for initial comment proposed amendments to Conduct Rule 2720 (the “Rule”) relating to conflicts of interest that occur between underwriters and issuers in the context of securities distributions (the “Proposal”). The Proposal substantially changes the Rule, and, as such, adjusts certain aspects of the underwriting process including: where the underwriter and the issuer are affiliates; where the underwriter or its affiliates (including venture capital and private equity arms) have an ownership interest in the issuer; and where the purpose of the securities offering is to repay debt owed to the underwriter or its affiliates.

NASD‐member broker‐dealers may seek to monitor the state of the Proposal in order to ensure that firm policies and procedures are consistent with future changes to the Rule. NASD members will also want to consider how the Proposal signals NASD's changes in thinking in respect of how they approach conflicts of interest in their own businesses.

Alerts practitioners and the industry to a new proposal that has significant consequences for underwriting, particularly in an age of increasingly global financial institutions.

Online collaboration in today's world is a topic of genuine interest to Internet researchers. The purpose of this paper is to explore the role of group knowledge heterogeneity (GKH) in open collaboration performance using the mediating mechanisms of group cognition (GC) and interaction to understand the determinants of the success of online open collaboration platforms.

Study findings are based on partial least squares structural equation modeling (PLS-SEM), the formal mediation test and moderating effect analysis from Wikipedia's 160 online open collaborative groups.

For online knowledge heterogeneous groups, open collaboration performance is mediated by both GC and collaborative interaction (COL). The mediating role of GC is weak, while the mediating role of COL is strengthened when knowledge complexity (KC) is higher. By dividing group interaction into COL and communicative interaction (COM), the authors also observed that COL is effective for online open collaboration, whereas COM is limited.

These findings suggest that for more heterogeneous large groups, group interaction would explain more variance in performance than GC, offering an in-depth understanding of the relationship between group heterogeneity and open collaboration performance, answering what determines the success of online open collaboration platforms as well as explaining the inconsistency in prior findings. In addition, this study expands the application of Interactive Team Cognition (ITC) theory to the online open collaboration context.

A cross-domain intelligent software-defined network (SDN) routing method based on a proposed multiagent deep reinforcement learning (MDRL) method is developed.

First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between the root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to acquire global network state information in real time. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a network traffic state prediction mechanism is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time.

Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and open shortest path first (OSPF) routing methods.

Message transmission and message synchronization for multicontroller interdomain routing in SDN have long adaptation times and slow convergence speeds, coupled with the shortcomings of traditional interdomain routing methods, such as cumbersome configuration and inflexible acquisition of network state information. These drawbacks make it difficult to obtain global state information about the network, and the optimal routing decision cannot be made in real time, affecting network performance. This paper proposes a cross-domain intelligent SDN routing method based on a proposed MDRL method. First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to realize the real-time acquisition of global network state information. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a prediction mechanism for the network traffic state is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time. Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and OSPF routing methods.

The large scale of construction projects and the coexistence of multiple logics in the construction field are sparking interest in applying an institutional perspective to investigate managerial issues in construction projects. However, only a few conceptual papers have been published thus far, and a literature review is needed to identify how that knowledge domain has developed. Based on the results of bibliometric analysis and content analysis, this study proposes potential future avenues for institutional theory in construction project management (ITCPM) studies.

This paper reports a bibliographic coupling analysis and a co-citation analysis conducted to identify existing research trajectories and determine the primary features of the current ITCPM literature. In addition, this paper employed a content analysis, identified the evolutionary stages of ITCPM knowledge over time and built a framework of existing research.

This paper first identified that the existing ITCPM studies evolve through three stages, and that the intellectual core of ITCPM studies can be categorized into five clusters. In addition, this paper proposes that future research can be extended from two existing streams: the institutional responses of project actors and the institutional outcomes of construction projects. This paper proposes several major questions that should be addressed by project management scholars working in both streams in order to develop an understanding of construction projects from an institutional perspective.

This is the first literature review of the existing body of knowledge based on a joining of institutional theory and construction project management literature. It uncovers knowledge gaps in contemporary research, notably a lack of broader consideration of how project actors respond to institutional environments and of the institutional outcomes of project management.

The purpose of this paper is to further explore the co-citation and bibliographic-coupling relationship among the core authors in the field of Chinese information science (IS), to expose research activity and author impact, and to make induction analyses about Chinese IS research patterns and theme evolution.

The research data include 8,567 papers and 70,947 cited articles in the IS field indexed by Chinese Social Sciences Citation Index from 2000 to 2009. Author co-citation analysis, author bibliographic-coupling analysis, social network analysis, and factor analysis were combined to explore co-citation and bibliographic-coupling relationships and to identify research groups and subjects.

Scholars with greatest impact are different from the most active scholars of Chinese IS; there is no uniform impact pattern forming since authors’ impact subjects are scattered and not steady; while authors’ research activities present higher independence and concentration, there is still no steady research pattern due to no deep research existing. Furthermore, Chinese IS studies can be delineated by: foundation or extension. The research subjects of these two parts, as well as their corresponding/contributing authors, are different under different views. The general research status of core authors is concentrated, while their impact is broad.

The combined use of some related methods could enrich the development and methodology research of the discipline, and the results establish a reference point on the development of IS research.

This study aims to investigate both the direct and indirect associations of environmental disclosures with financial performance, environmental performance and firm value.

The samples are companies listed on the Indonesia Stock Exchange in the agriculture industry, mining industry, basic industry and chemicals, miscellaneous industry and consumer goods industry and that are participating in the Performance Rating Assessment Program on Environment Management (PROPER/Program Penilaian Peringkat Kinerja Perusahaan) of the Ministry of the Environment Republic of Indonesia or have been awarded the Green Industry Award by the Ministry of Industry Republic of Indonesia in 2012-2014. Data are collected from sustainability reports, annual reports and annual financial statements. The authors used simultaneous equation modeling and panel data regression analysis to analyze the data.

The authors find that the financial performance does not affect the environmental disclosures. The lagged environmental performance has a positive effect on the current environmental disclosures, and environmental disclosures do not affect the firm market value and do not mediate the effect of financial performance and environmental performance on firm value.

This study comprehensively examines both direct and indirect associations of environmental disclosures with financial performance, environmental performance and firm value, which is rarely examined in extant studies.

Electric spring (ES) is a demand response method that can stabilize the voltage of critical loads and improve power quality, especially in a weak power grid with a high proportion of renewable energy sources. Most of existing ESs are implemented by voltage-source inverter (VSI), which has some shortcomings. For example, the DC-link capacitor limits the service life of ES, and the battery is costly and hard to recycle. Besides, conventional VSI cannot boost the voltage, which limits the application of ES in high-voltage occasions. This study aims to propose a novel scheme of ES to solve the above problems.

In this work, an ES topology based on current-source inverter (CSI) without a battery is presented, and a direct current control strategy is proposed. The operating principles, voltage regulation range and parameter design of the proposed ES are discussed in detail.

The proposed ES is applicable to various voltage levels, and the harmonics are effectively suppressed, which have been validated via the experimental results in both ideal and distorted grid conditions.

An ES topology based on battery-less CSI is proposed for the first time, which reduces the cost and prolongs the service time of ES. A novel control strategy is proposed to realize the functions of voltage regulation and harmonic suppression.

Based on the dynamic capability theory, our study tries to explore the mediator mechanism of service supply chain dynamic capability between market orientation and service innovation performance, as well as the boundary conditions in which service supply chain dynamic capability plays a role, in order to reveal the key elements and their mechanisms for manufacturing enterprises to improve service performance.

With a total of 317 valid questionnaires, structural equation modeling (SEM) was used to test the research model and hypotheses.

The empirical results confirm that the three types of service supply chain dynamic capability (environment insight capability, resource integration capability and resource reconfiguration capability) can partially mediate the relationship between firm market orientation (responsive and proactive market orientations) and service innovation performance. In addition, supply chain collaboration has different types of moderator effects on the relationship between the three types of service supply chain dynamic capability and service innovation performance.

This research discovers that market orientation and dynamic capability are the key factors leading to high service performance and reveals the mediating role of service supply chain dynamic capability between market orientation and service innovation performance. Moreover, this research explores the moderating role of supply chain collaboration in service supply chain resource reconfiguration capability and service innovation performance.

The purpose of this paper is to investigate whether ex ante board connections and director retention result in agency costs to target company shareholders in the form of reduced payment in mergers and acquisitions transaction.

The authors employ detailed data of ex ante board connection and director retention in the mergers and acquisition in the UK from 1999 to 2015. Ex ante board connections are measured as proportion of target and acquirer companies’ directors worked on the same board at any time prior to the takeover, while director retention is measured as proportion of target companies’ directors remains on board after the takeover is completed. For mergers and acquisition payment characteristics, the authors examine takeover premium, cash payment percentage and offer price adjustment.

The authors find that ex ante board connections and director retention lead to reduced offer prices and lower proportions of cash payment. Notably, when there is no connection and target directors are not retained, the authors find that the bidding companies increase their final offer by £14m more than in other scenarios. The authors also document strong evidence that ex ante board connections lead to a higher probability of director retention.

The paper highlights that ex ante board connections and director retention will lead to a significant cost on target company shareholders. The authors recommend that a more detailed set of information on ex ante board connections and intended target board retention should be disclosed.

Librarians are challenged by technology transformations in research data metrics to re-position in the evolving cycles of research production, communication and evaluation. They are also are challenged by the new and emerging strategic needs of universities for data-driven research intelligence that provides a comparative edge in the global world of higher education. This paper aims to discover how libraries can support universities in applying international assessment standards by delivering new reference and information services based on data analytics.

This paper focuses on a new reference and information service Research Data Analytics in China that was launched in 2017. There is a discussion of how new university needs have provided the strategic drive for librarians to develop skills.

The Research Data Analytics service development is significant for showcasing a new role for librarians in relation to research data evaluation metrics linked to publication strategies for authors and strategic intelligence for institutions. This has driven the development of the library’s position and influence in strategic research intelligence services.

The future for librarians is about being adventurous. Librarians are experts who will sparkle and shine beyond the bubble of the library walls. They can demonstrate a commitment to supporting university colleagues in professional services and academia to blossom and flourish. Distinctive visual technologies can be adopted for exploring research data which transform research production, communication and evaluation and therefore transform our position and future through technology-enabled innovations.
