Nowadays, WiFi indoor positioning based on received signal strength (RSS) becomes a research hotspot due to its low cost and ease of deployment characteristics. To further improve the performance of WiFi indoor positioning based on RSS, this paper aims to propose a novel position estimation strategy which is called radius-based domain clustering (RDC). This domain clustering technology aims to avoid the issue of access point (AP) selection.

The proposed positioning approach uses each individual AP of all available APs to estimate the position of target point. Then, according to circular error probable, the authors search the decision domain which has the 50 per cent of the intermediate position estimates and minimize the radius of a circle via a RDC algorithm. The final estimate of the position of target point is obtained by averaging intermediate position estimates in the decision domain.

Experiments are conducted, and comparison between the different position estimation strategies demonstrates that the new method has a better location estimation accuracy and reliability.

Weighted k nearest neighbor approach and Naive Bayes Classifier method are two classic position estimation strategies for location determination using WiFi fingerprinting. Both of the two strategies are affected by AP selection strategies and inappropriate selection of APs may degrade positioning performance considerably.

The RDC positioning approach can improve the performance of WiFi indoor positioning, and the issue of AP selection and related drawbacks is avoided.

The RSS-based effective WiFi indoor positioning system can makes up for the indoor positioning weaknesses of global navigation satellite system. Many indoor location-based services can be encouraged with the effective and low-cost positioning technology.

A novel position estimation strategy is introduced to avoid the AP selection problem in RSS-based WiFi indoor positioning technology, and the domain clustering technology is proposed to obtain a better accuracy and reliability.

Many experts suggest that the human being explore marine resources and marine new energy sources to alleviate the shortage of land resources and the ecological degradation. However, island coastal zones are considered to be fragile ecosystems; their geographical location and natural characteristics, their biodiversity and associated ecosystems, and their exposure to diverse land and sea conditions all make them highly vulnerable to environmental changes and human activities. Therefore, it is necessary to achieve the goals of environmental protection and sustainable development on the basis of a comprehensive evaluation and understanding of islands.

Due to the importance of island groups, this paper conducts evaluation studies on them. Using the Delphi, AHP and TOPSIS methods, this study evaluated quantitatively the comprehensive development level and comprehensive development potential of island groups in terms of resources, natural environment, economy and society. Innovatively using them as two subsystems, the present study combined the coupling coordination model and the obstacle factor calculation method.

The prospective index of comprehensive development was applied to the Changdao Island Group in Yantai, Shandong Province as an example, and the final evaluation revealed that the comprehensive development prospect of this island group had an upward trend from 2010 to 2017. Future efforts should be made to improve its economic and social conditions and economic development status, apart from promoting its comprehensive development by improving human resources management, increasing the GDP growth rate, and improving fresh water and electricity supply.

This study takes the integrated development level of the island and the integrated development potential of the island as two subsystems, and the innovative application of the coupling coordination degree model is used to calculate the integrated development index of the island to understand the development status of the island area. On the basis of this model, the obstacle factor identification method is designed to identify the main obstacle factors, and on the basis of evaluation and identification, specific measures to ensure the sustainable development of the island area are effectively proposed.

The island areas, in particular, are characterized by a more fragile ecological carrying capacity and higher value of resources and environment, which requires us to take Xi Jinping's green ecological development view as the theoretical basis and adhere to the high-quality development path of gradual development and ecological environment priority. Taking Shengsi and Daishan counties as examples, on the basis of their high-quality development evaluation and identification of the main influencing factors, this study explores the specific path of Xi Jinping's ecological development view in the high-quality development of typical island counties in China.

This paper applies the interpretative structural model to construct an evaluation index system for the high-quality development of the island. In determining the factor weights of the index layer, the AHP hierarchical analysis method was combined with the Delphi method to increase the objectivity of the assignment process as much as possible. This study used the technique for order of preference by similarity to ideal solution to calculate island high quality development index. To measure the main obstacle factors, the index factor contribution rate, the index factor deviation, and the index factor obstacle degree were applied in this research.

As China intensifies its maritime strategy, the sustainability of coastal and island regions is critical, particularly given their fragile ecosystems and high resource value. Our study reveals a declining trend in the high-quality development index for Shengsi, peaking at 0.4262 in 2010 and dropping to 0.3261 in 2012. To reverse this, it's essential to align with President Xi Jinping's green ecological development framework and commit to a high-quality development pathway.

The connotation and extension of Xi Jinping's view of ecological development should be continuously studied in depth and enriched, with green development as the core idea to guide the correct direction of the high-quality development of the island. In this paper, it is suggested that researchers are supposed to focus on these problems, such as the changes of sea water quality, the reduction of urban greening, the continuous negative growth of population in island areas, the decline of forestry added value and air quality protection, so as to ensure the sustainable high-quality development of example islands.

The purpose of this paper is to present a robust control design method for uncertain multi‐time‐delay linear system.

Delay‐dependent stability conditions are given based on time‐dependent Lyapunov‐Krasovskii functional. By using the key technical lemma (Lemma 1) and the Schur Complement Lemma, the robust control design problem is transferred to the problem of solving several linear matrix inequalities, which can be easily realized by MATLAB Toolbox.

Delay‐dependent stability analysis and control design are less conservative than delay‐independent one, theoretically.

Both state delay and input delay are studied in this paper. Moreover, the uncertainties considered include not only parameter uncertainties, but also noise disturbance.

This study examines how budgetary support (BS), teamwork, and organizational commitment to employees (OCE) affect firm performance across two countries, Malaysia and the United States. By surveying senior managers of 165 small and medium enterprises, this study finds that teamwork and BS each has a direct effect on OCE and firm performance. Further, results indicate that OCE mediates the relationship between BS, teamwork, and firm performance. In Malaysia, but not in the United States, we find that teamwork affects performance directly. In the United States, but not in Malaysia, we find that BS affects performance, and there is an interaction effect between BS and management influence. We attribute the effects to the different national cultures and social-exchange relations and highlight the contributions to the budgeting research, organizational commitment literature, and to practice.

The current study seeks to provide predictions for task conflict in supervisor‐subordinate dyads and to test empirically the mediation effects of task conflict between organizational culture/subordinate values and subordinate outcomes.

Structural equation modeling was employed to test the theoretical model.

It was found that task conflict mediates the relationship between a clan culture and intention to quit. Additionally, support was also found for the mediating effect of task conflict on the relationship between individualistic values and intention to quit.

More research is needed to take into consideration the variables influencing task conflict in both vertical and horizontal dyadic relationships. A dynamic view of conflict may further contribute to the existing literature.

More remedies are needed in organizations to foster positive employees' attitudes and wellbeing through the generation of task conflicts. For example, fostering a clan culture instead of a hierarchy may be vital.

The current study demonstrates that organizational culture/subordinate's values may be linked to different subordinate outcomes through task conflict.

Applying brand names to international markets remains a challenge to multinational corporations. Consumers’ sociolinguistic backgrounds shape their responses to brand names. This paper uses a sociolinguistic approach as a conceptual framework in understanding brand naming and translating in the Chinese market. The approach promotes that sociolinguistics a) recognizes linguistic competence, b) advances symbolic values imbedded in linguistic forms, and c) renders attached social valence to cultural scrutiny. Three brand‐naming cases in China are presented for discussion, which may benefit multinational corporations on brand decisions involving Chinese consumers.

A number of interventions aimed at increasing breakfast consumption have been designed and implemented in recent years. This paper seeks to review the current research in this area with the aim of identifying common features of successful interventions and strengths and weaknesses in the current research methodology.

A systematic review of interventions aimed at increasing breakfast‐eating frequency in a non‐clinical sample was conducted.

A total of 11 interventions were identified and reviewed; of these, only three resulted in an increase in breakfast consumption at follow‐up. The three studies that were successful in changing breakfast consumption all included a psychosocial component that was successful in increasing positive attitudes towards nutrition in the intervention protocol. Many of the breakfast‐eating interventions included in this review have methodological weaknesses, including difficulties in implementing interventions, small sample sizes, and selection biases, which future researchers should consider when designing and evaluating their own interventions.

These findings highlight the importance of including psychosocial components in interventions designed to increase breakfast consumption, while also signalling issues that should be addressed when designing and reporting future interventions.

This review was the first to investigate the efficacy of interventions aimed at increasing breakfast consumption. The identification of weaknesses in the current body of research, and of successful and unsuccessful intervention practices is an important step in developing successful interventions in the future.

The relationship between human resource management practices (HRMP) and innovation has been described as a black box, where a lot still needs to be investigated. Thus, the aim of this paper is to investigate the nature of the link that exists between HRMP and innovation in both public and private organizations. To do so, theoretical underpinnings and existence of a mediating or a moderating mechanism is inspected.

Based on an empirical systematic review of research conducted between 2010 and 2018, content analysis has been conducted for 31 peer-reviewed articles in the English language.

Inspecting the nature of relations existed in the chosen articles, interesting findings are addressed relative to the nature of the human resource management systems (HRMS) used, practices encompassed and their different utility. HRMS has been shown to be associated with product innovation yet more evidence is needed for supporting process innovation.

The HRMS/HRMP and innovation relationship is inspected, important practices that would guide managers to induce innovation are highlighted. Usage of multiple HRMS and contingency in constructing such systems is indicated.

Contribution to comprehend the black box and areas for future research has been offered.

The purpose of this study is to understand the role of customer engagement (CE) in transforming a committed customer into a loyal customer in an online service context. The study explores the varied effect of the dimensions of commitment on the dimensions of beyond purchase CE and their effect on loyalty.

The study uses a survey for data collection and assesses the measurement model with confirmatory factor analysis and uses partial least square-structural equation modeling for the structural model.

The study reveals that the constructs commitment, CE and loyalty are interrelated. It empirically supports that the affective and continuance commitment has a significant positive association with CE, and two out of the three dimensions of CE have a significant positive association with loyalty.

This study advances the understanding of the relationship between commitment, CE and loyalty and supports the conceptualization of CE as a behavioral construct. The study uses cross-sectional data, which miss the effect of the time lag of the constructs and use of the context of travel booking websites limits its generalization.

This study helps marketers to understand CE, what motivates CE, its impact on the firm and how to align CE strategies with the firm’s goal.

This study proposes a conceptual model for how CE transforms commitment into loyalty. It improves the understanding of CE’s conceptualization, its drivers and its impact on brand loyalty.
