Sagawa and Ueda established a fluctuation theorem of information exchange by revealing the role of correlations in stochastic thermodynamics and unified the non-equilibrium thermodynamics of measurement and feedback control. They considered a process where a non-equilibrium system exchanges information with other degrees of freedom such as an observer or a feedback controller. They proved the fluctuation theorem of information exchange under the assumption that the state of the other degrees of freedom that exchange information with the system does not change over time while the states of the system evolve in time. Here we relax this constraint and prove that the same form of the fluctuation theorem holds even if both subsystems co-evolve during information exchange processes. This result may extend the applicability of the fluctuation theorem of information exchange to a broader class of non-equilibrium processes, such as a dynamic coupling in biological systems, where subsystems that exchange information interact with each other.

Changes Over Time

Companies are required by law to report all kinds of information to various public agencies. Since most public agencies are autonomous and define their information demands independent of each other, companies have to report information to various agencies in different ways. Accordingly, governments are initiating programs that aim to transform business-to government information exchange to reduce the administrative burden for companies and improve the accountability at the same time. Yet little research is available on the type of transformations needed and the role of the infrastructure. Drawing on a case study, this paper investigates the interplay between technical infrastructure and transformation. In this case study an information brokerage infrastructure based on the Extensible Business Reporting Language (XBRL) was developed providing a one stop shop for companies and public agencies. The case study shows that the infrastructure should be flexible enough to accommodate changes over time but stable enough to attract a large user-base. The increase in efficiency and effectiveness of information exchange processes requires extensive transformation from both public and private parties.

The Subject

Exchange has been known as the subject matter of Marketing. In this decade, Internet has enabled people to connect and exchange information to others, regardless of time and space. This condition leads to a new phenomenon, known as social networking through social network sites. In social network sites members find new kinds of exchange, which is information exchange. Memberships in many social network sites are free, which means that everyone is free to join or leave it. In that case social network providers must ensure that members keep using their site. The aim of this study is to test and analyze the direct and indirect effect of exchange to loyalty. The Unit of analysis in this study were members of social networking sites Friendster and Facebook. There are 256 respondents participate in this research. The result shows if community members keep exchange activity, they will loyal to the community. Direct effect has greater impact on loyalty than indirect effect. This means that social network company must encourage their member to exchange information actively.

Purposeful Activity

The article investigates the role of communicative-functional approach in the translation of scientific and technical literature, when the translation itself is seen as a tool to accomplish purposeful activity of communicators, representatives of different interlingual groups. In practical terms, the difficulties of translating scientific and technical texts are due to the peculiarities of scientific style, insufficient understanding of the terminology of a particular field of knowledge, which complicates the choice of adequate translation solutions. In this context, an important role is played by the translation strategy, where the communicativefunctional approach dominates. The translation is implicitly included in the communication structure between the author and the recipient. The relevance of the article is determined by the necessity of studying the problems of scientific and technical literature translation, taking into account the current realities of interlanguage information exchange. Key words: communicative-functional approach, interlingual communication, translation, structure

<div> <div> <div> <p>In the present work we have investigated the possibility of using the Quantum Thermal Bath (QTB) method in molecular simulations of unimolecular dissociation processes. Notably, QTB is aimed in introducing quantum nuclear effects with a com- putational time which is basically the same as in newtonian simulations. At this end we have considered the model fragmentation of CH4 for which an analytical function is present in the literature. Moreover, based on the same model a microcanonical algorithm which monitor zero-point energy of products, and eventually modifies tra- jectories, was recently proposed. We have thus compared classical and quantum rate constant with these different models. QTB seems to correctly reproduce some quantum features, in particular the difference between classical and quantum activation energies, making it a promising method to study unimolecular fragmentation of much complex systems with molecular simulations. The role of QTB thermostat on rotational degrees of freedom is also analyzed and discussed. </p> </div> </div> </div>

Negative Effect

Purpose This paper aims to systematically investigate the direct and indirect effects of four types of support – peer instrumental support, peer emotional support, platform business support and platform communication support – on seller trade volume in social commerce. It also aims to uncover the path of support-to-sales of the seller from a platform perspective and provides a more complete picture of the social commerce phenomenon. Design/methodology/approach This paper uses multi-source data including primary survey data and secondary data on trade volume to test the hypotheses. PROCESS mediation model is used to analyze the multi-source data set. Findings This study finds that the positive effects of peer instrumental support, platform business support and platform communication support on seller trade volume are fully mediated by seller collaborative information exchange. Also, peer emotional support has a significant negative effect on seller trade volume and collaborative information exchange can serve as a buffer to mitigate the negative effect. Research limitations/implications The authors provide new insights into what types of support are or are not conducive to improving transaction volume of individual sellers and highlight the mediating role of seller information exchange in this value generation process in social commerce. These findings advance current knowledge of how seller interactions increase value in social commerce. The chosen research setting may limit the generalizability of the findings of this study. Practical implications This paper offers valuable implications for social commerce platforms on how to better serve their sellers to achieve high growth. Specifically, the findings suggest that platforms should encourage instrumental support and information exchange among peer sellers. In addition, platforms should expand seller support from a single-focus on sellers’ business to a dual-focus on both sellers’ business and socialization in social commerce. Originality/value This paper fulfills an identified need to study how sellers can better derive value from the social interactions and how social commerce platforms can effectively influence transactions, support sales and serve as a selling platform.

AbstractDzyaloshinskii–Moriya interaction (DMI) is considered as one of the most important energies for specific chiral textures such as magnetic skyrmions. The keys of generating DMI are the absence of structural inversion symmetry and exchange energy with spin–orbit coupling. Therefore, a vast majority of research activities about DMI are mainly limited to heavy metal/ferromagnet bilayer systems, only focusing on their interfaces. Here, we report an asymmetric band formation in a superlattices (SL) which arises from inversion symmetry breaking in stacking order of atomic layers, implying the role of bulk-like contribution. Such bulk DMI is more than 300% larger than simple sum of interfacial contribution. Moreover, the asymmetric band is largely affected by strong spin–orbit coupling, showing crucial role of a heavy metal even in the non-interfacial origin of DMI. Our work provides more degrees of freedom to design chiral magnets for spintronics applications.
