To cope with climate change and achieve the dual carbon goal, China has actively promoted the implementation of carbon trading pilot policy, among which the power industry plays an important role in China’s carbon emission reduction work. The purpose of this paper is to study the influence of carbon trading policy on the energy efficiency of power industry and achieve the comprehensive goal of carbon emission reduction, carbon peak and carbon neutralization.

This paper constructs the difference-in-differences model based on 2012–2019 provincial data to study the impact of carbon trading policy on energy efficiency in the power industry and its effect path. Heterogeneity analysis was conducted to compare the effects of carbon trading policy in eastern, central and western regions as well as at different levels of power structures.

Carbon trading policy can significantly improve the energy efficiency of the power industry, and the policy effect is more significant in eastern and western regions and areas with high power structure. Mechanism analysis shows that carbon trading policy mainly influences the energy efficiency of power industry by environmental protection investment, power consumption demand and industrial structure.

This paper uses provincial panel data to deeply study the influence of carbon trading policy on energy efficiency of the power industry and its effect path. By constructing the difference-in-differences model, this paper empirically analyzes the governance effect of carbon trading policy. Meanwhile, it controls individual and time effects to solve the endogeneity problem prevalent in previous literature.

Subjects participated in a three‐person negotiation exercise, in which they had to form two‐ or three‐way coalitions to receive resources. The effects of power position (high, medium, low), distribution norms (contribution, need), and task meeting structure (caucus, joint) on the distribution of resources were examined. Most coalition theories assume that the power position of the players calls into play different levels of entitlement which will determine the allocation of resources. There has, however, been little attempt to manipulate entitlement, in the form of distribution norms, separately from power structure. In the research reported here, three‐person groups contained a high, medium, and low power player. The dominant group distribution norm was manipulated as either contribution‐based or need‐based. Task meeting structure was manipulated by beginning each group meeting with either a three‐way meeting between all players (joint) or a series of one‐on‐one meetings (caucus). As predicted, groups that began by caucusing had a higher incidence of two‐way agreements than groups that began with joint meetings. The task meeting structure interacted with power position such that caucusing increased the high power player's outcome, while the joint meeting structure increased the low power player's outcome. In addition, the distribution norm interacted with power position such that the contribution‐based norm increased the outcomes of high power players, while the need‐based norm increased the outcomes of the low power players.

Problems arose in the “market for information” (MFI) during the “dot.com” boom, the Enron case, Northern Rock failure and during the great financial crisis (GFC) of 2007-2009. This paper aims to extend the understanding of the MFI through field research and theoretical sources. It also aims to understand the MFI during relatively stable periods and during periods of rapid change, crisis and failure. It seeks to use these insights to propose changes to reduce the possibilities for negative change and problems in the MFI.

Field studies are used to develop an “empirical narrative” for ongoing MFI structures, processes and outcomes during relatively stable periods. The paper develops a “theoretical narrative” to extend the understanding of the MFI empirical insights.

The paper reveals that the MFI structure that includes knowledge and social context is central to ongoing MFI economic processes for MFI agents. Outcomes include changes in markets, firms and others. Changes and problems are means to understand interactions between the MFI social structure, knowledge, actions and outcomes as they rendered visible the previously invisible issues.

The paper shows that a coherent combination of new empirical narrative and theoretical narrative is essential to develop a critical stance, new policy prescriptions and new regulations to deal with problems and changes in the MFI. This provides the frame to propose changes in the “world of knowledge” and in (concentrated and elite) social and economic structures in the MFI. It proposes: making explicit shared knowledge in the MFI, monitoring change processes and promoting active formal learning.

The purpose of this paper is to propose a new design strategy to enhance the bandwidth and efficiency of the power amplifier.

To realize the introduced design strategy, a power amplifier was designed using TSMC CMOS 0.18um technology for operating in the Ka-band, i.e. the frequency range of 26.5-40 GHz. To design the power amplifier, first, a power divider (PD) with a very wide bandwidth, i.e. 1-40 GHz, was designed to cover the whole Ka-band. The designed Doherty power amplifier consisted of two different amplification paths called main and auxiliary. To amplify the signal in each of the two pathways, a cascade distributed power amplifier was used. The main reason for combining the distributed structure and cascade structure was to increase the gain and linearity of the power amplifier.

Measurements results for designed power dividers are in good agreement with simulations results. The simulation results for the introduced structure of the power amplifier indicated that the gain of the proposed power amplifier at the frequency of 26-35 GHz was more than 30 dB. The diagram of return loss at the input and output of the power amplifier in the whole Ka-band was less than −8dB. The maximum power-added efficiency (PAE) of the designed power amplifier was 80%. The output P1dB of the introduced structure was 36 dB and the output power of the power amplifier was 36 dBm. Finally, the IP3 value of the power amplifier was about 17 dB.

The strategy presented in this paper is based on the usage of Doherty and distributed structures and a new wideband power divider to benefit from their advantages simultaneously.

Emphasis is placed on knowledge-sharing practices and their influence on the power structure influenced by the technological background of the organization. This paper aims to focus on technological skills institutionalized to build organizational technological capital favoring the knowledge-sharing practices. It aims to extend the sociology literature by providing a conceptual background to explain the restructuring initiatives through the stabilizing role of technological capital.

Two comparative case studies have been conducted: the first study took place in a public company and the second study was carried out in a private company of telecommunication involving a documentary study, an observation and semi-structured interviews.

The findings in this paper show that the knowledge-sharing practices in the organizational field are stabilized by the technological capital. The technological capital promotes a knowledge management system and plays an important role in restructuring the established power within knowledge intensive organizations.

Chief executive officers are encouraged to promote sharing practices through developing an innovation culture and valuing technological skills. Relevance should be granted to the technological capital, which aligns the restructuring of a learning organization and promotes the knowledge management systems and stabilizes the organizational structure. Organizations should capitalize a set of technological skills as part of their organizational relevant capital.

Based on the practice theory of Bourdieu, this paper lights on the triad relation between knowledge sharing/organizational structure/technological capital through comparing between public/private management modes. A theoretical framework is proposed to overlap the ambiguity of the relation between knowledge and power.

New institutionalisms in economic and organizational sociology need grounding in theories of capitalism. Comparative studies show that multiple, viable forms of capitalism have been constructed through the interplay of institutions, mobilizations of political power, and state policies. Further theoretical development requires attention to the contradictions of capitalism. Promising theoretical sources for this task are examined. The political process produces new forms of capitalist institutions, but contradictions built into those institutions cannot be fully resolved and provide the basis for new acts of social construction and power mobilization. The power and cultural arguments of the comparative institutionalists are joined, at least in aspiration, to theories of capitalist contradictions.

This paper aims to study the preferences of the supply chain (SC) members on various power structures under demand information asymmetry considering competing retailers.

A two-level SC with one manufacturer and two retailers is designed. The retailers are in Bertrand competition. The manufacturer who holds the confidential demand information chooses the appropriate information sharing (IS) format. Three IS formats are provided, i.e. no IS (the manufacturer never shares with the retailers), partial IS (the manufacturer shares with one retailer), full IS (the manufacturer shares with all retailers). In addition, the authors model two power structures based on the decision sequences in the SC, i.e. retailers or manufacturer-dominant SC. The authors characterize the equilibrium solutions and payoffs and then investigate the members’ preferences for IS formats.

It is shown that in retailers (manufacturer)-dominant SC, the retailers prefer full (no) IS, but the manufacturer prefers no (full) IS. Moreover, the authors analyze the members’ preferences on power structures under demand information asymmetry, which has a relationship with the degrees of demand uncertainty and competition intensity.

The analysis regarding the preferences of the SC members on power structure under demand information asymmetry provides valuable managerial insights to enhance cooperation and achieve a win-win result.

Since its resurrection during the 1980s, comparative-historical sociology has been repeatedly critiqued on two fronts. Quantitative methodologists have argued that its “causal inferences” are unreliable due to its “small n.” And methodological individualists have argued its explanatory accounts are unacceptable because they do not specify “microfoundations.” But these critiques are built on faulty foundations, namely, a regularity theory of causation and a reductionist social ontology. In this article, I propose an alternative foundation derived from Critical Realism: a production theory of causation and an emergentist account of social structure.

This chapter develops a sketch of a critical social ontology and contrasts it to a theory of sociality as presented in the work of Michael Brown. I argue that the ontology of our social forms requires categories for understanding them descriptively, functionally as well as in evaluative terms. I contend that a theory of power is needed for an understanding of the ontology of our social forms and that this can contribute to the construction of a more critical social ontology. I argue that a critical social ontology is a more attractive and satisfying paradigm for critical theory than current post-metaphysical approaches that emphasize discourse, recognition or other neo-Idealistic aspects of human sociality.
