The Impact of Social Media Usage on Work Efficiency: The Perspectives of Media Synchronicity and Gratifications

As prevail of mobile networking, social media became ubiquitous in either work or our personal life. Based on Media Synchronization Theory and transformational framework, this study proposed a research model and examined how the social media' attributes impacting the work effectiveness through the work-oriented or social-oriented usage. The data of 322 valid questionnaires from respondents was analyzed by SmartPLS 3.2.8. The results indicated that the features of social media including availability and symbol variety had the significant influences on their work efficiency through work-oriented usage of social media. Publicness and symbol variety had impact on work efficiency via social-oriented usage of social media. In addition, both social media for work-oriented and social-oriented usage influenced employees' work efficiency. There were different considerations when people selected social media for work or for social purpose. Managers or companies could guide their employees to use the social media in a right way to increase their work features to complete their work efficiency, and create groups for employees so the work information could be shared efficiently.

Media Entertainment, Flow Experiences, and the Synchronization of Audiences

Media entertainment frequently elicits rapt attention, loss of self-consciousness, high levels of enjoyment along with a sense that time is passing more quickly or more slowly than usual. This state is often referred to as flow. For over two decades, scholars have sought to understand when and why media produce flow experiences in audiences. The synchronization theory of flow (STF) advanced flow research by specifying the neural underpinnings of flow experiences and how these neural substrates are influenced by entertaining media. In the intervening years, research from a variety of fields has provided support for the core predictions of STF and has highlighted promising areas for future investigation. This chapter reviews the current state and future directions of STF, focusing on its potential for creating a bridge between media entertainment research and other vibrant research domains including motivated decision-making and neuroaesthetics.

Disharmonisasi Periode Pemberlakuan Rencana Induk Pembangunan Kepariwisataan Daerah di Indonesia (Implementasi Peraturan Pemerintah Nomor 50 Tahun 2011 tentang Rencana Induk Pembangunan Kepariwisataan)

Regional autonomy brings consequences for each region to take care of and explore its potentials. Moreover, the region is given options to manage the tourism sector which is potential to optimize the development of the district. The composition of tourism in Indonesia consists of regional up to national levels by concerning the diversities, uniqueness, and peculiarities of its culture and nature. Consequently, as mentioned in Act No. 10 of the year 2009 concerning tourism of article 8 mentioned that tourism development is conducted based on the master plan for tourism development is an integral part of the national long-term development plan. Therefore, the planning duration of RIPPARPROV and RIPPARKAB/KOTA also adjusts to the period of the Regency/city long-term development plan which is the period is same as the national long-term development plan (RPJP). However, the implementation of tourism law is not optimal due to some of the main tourism plans having disharmony on the scale of its validity periods such as RIPPAR-Prov East Java and Central Java, or RIPPAR-Kota Surakarta and Balikpapan. Through the Yuridis-normative research method and the approach of statutory and conceptual regulations, researchers focus on analyzing the consequences of the disharmony of the main tourism plan base on 3 (three) theories of law which are synchronization theory, harmonization theory, and legal development theory.

Synchronization Theory-Based Analysis of Coupled Vibrations of Dual-Tube Coriolis Mass Flowmeters

Certain nonlinear influences are found in dual-tube Coriolis mass flowmeters (CMFs). According to experimentation, a nonlinearity dominated by frequency-doubling signals can be observed in the measuring signal. In general, such nonlinear effects are simplified as linear systems or neglected through processing. In this paper, a simplified model has been constructed for dual-beam CMFs based on the theory of nonlinear dynamics, with the spring–damper system as the medium for the dual-beam coupled vibrations. Next, the dynamics differential equation of the coupled vibrations is set up on the basis of the Lagrangian equation. Furthermore, numerical solutions are obtained using the Runge–Kutta fourth-order method. The study then fits discrete points of the numerical solutions, which are converted into the frequency domain to observe the existence of frequency-doubling signal components. Our findings show that frequency-doubling components exist in the spectrogram, proving that these nonlinear influences are a result of the motions of coupled vibrations. In this study, non-linear frequency-doubling signal sources are qualitatively analyzed to formulate a theoretical basis for CMFs design.

Global synchronization of coupled reaction–diffusion neural networks with general couplings via an iterative approach

We establish a framework to investigate the global synchronization of coupled reaction–diffusion neural networks with time delays. The coupled networks under consideration can incorporate both the internal delays in each individual network and the transmission delays across different networks. The coupling scheme for the coupled networks is rather general, and its performance is not adversely affected by the restrictions commonly imposed by existing relevant investigations. Based on the proposed iterative approach, the problem of global synchronization is transformed into that of solving the corresponding homogeneous linear system of algebraic equations. The synchronization criterion is subsequently derived and can be verified with simple computations. Three numerical examples are presented to illustrate the effectiveness of the synchronization theory presented in this paper.

Experimental and theoretical investigation on synchronization of a vibration system flexibly driven by two motors

With the increasing requirements for screening new materials, such as high-density and high-viscosity drilling fluids, it is necessary to increase the exciting force of the shale shaker to fully handle the new materials. To increase the exciting force of shale shaker while improving the force condition, a dynamic model of a vibration system flexibly driven by two motors is proposed in this paper. The dynamic behavior and synchronization theory of this system are investigated by using Lagrange equation and Hamilton’s principle. The calculation proves that the conventional planar vibration system rigidly driven by two motors is a special case of the investigated spatial vibration system flexibly driven by two motors. The phase difference between the eccentric rotors is automatically adjusted by the system to balance the change in the motor installation position for maintaining synchronization and stability. Theoretical investigation and experimental verification prove that the system can synchronize vibration without additional control synchronization.

Synchronization: a framework for examining emotional climate in classes

This conceptual paper stems from a growing body of research examining the roles and functions of emotional climate (EC)—the collective state of students’ shared emotions—in classrooms. It suggests that EC in classrooms can be analyzed as a synchronization phenomenon. Synchronization is a natural phenomenon, in which autonomous objects that produce periodic rhythms adjust these rhythms to one another. The purpose of this article is thus twofold: to position the concept of EC within the broader context of synchronization theory; and to propose a new definition for EC that captures synchronization aspects. This paper first explains the theory of synchronization. It then critically discusses several sociological and biological theories regarding emotions, and the implications of these theories for teaching and learning. It subsequently delves into current conceptualizations of EC, and the descriptors used to characterize EC in classrooms. On the backdrop of this theoretical review, an argument is developed that humans’ produced emotions can be viewed as autonomous rhythmic oscillators that have the capacity to synchronize with one another, and that, consequently, EC can be studied as a form of synchronization within an ensemble of oscillators. Finally, a new definition of EC is proposed that integrates essential synchronization features. Overall, this paper suggests that synchronization theory can provide a framework of analysis of EC as a holistic phenomenon, not reduced to discrete emotional events. This approach may contribute to enhancing explanatory and predictive capacities in the study of EC.

Outer-synchronization of fractional-order neural networks with deviating argument via centralized and decentralized data-sampling approaches

This paper is committed to investigating outer-synchronization of fractional-order neural networks with deviating argument via centralized and decentralized data-sampling approaches. Considering the low cost and high reliability of data-sampling control, we adopt two categories of control strategies with principles of centralized and decentralized data-sampling to synchronize fractional-order neural networks with deviating argument. Several sufficient criteria are proposed to realize outer-synchronization by data-sampling control design in two complex coupled networks. It is noteworthy that, based on centralized and decentralized data-sampling methods, the synchronization theory of fractional systems and differential equation with deviating argument, the sampling time points are very well selected in control systems. An example is performed to illustrate the advantage of the presented theoretical analysis and results.
