The purpose of this paper is to propose a framework for evaluating the relationship between China and Peru, drawing on dependency theory, against the backdrop of China’s explicit policies towards foreign direct investment. It seeks to transcend traditional interpretations of this relationship in the literature that focuses on China as either hegemon or a South–South partner to Latin American countries to highlight a more nuanced relationship.

The paper adopts a case study approach, focusing on China in Peru. The authors examine three areas of traditional, strategic and emerging industries drawing from Chinese national policies, reviewing these against characteristics of dependency: control of production, heterogeneity of actors, transfer of knowledge and delinking.

The authors find that Chinese foreign direct investment (FDI) in Peru demonstrates mixed motives and collectively operates as an ambiguous player. Chinese firms appear to be willing to work with various actors, but this engagement does not translate into a decolonial development alternative in the absence of a Peruvian political will to delink and Chinese willingness to actively transfer control of production and knowledge.

This paper contributes to existing literature on China in Latin America by evaluating Chinese outward FDI in Peru against China’s strategic aims in terms of a re-evaluation of dependency theory.

The purpose of this paper is to examine the relationship between dividend policy and earnings quality of Vietnamese listed firms.

The sample includes firms listed on Vietnam stock exchange during the period between 2010 and 2016. Two measures of earnings quality are the annual firm-specific absolute value of residuals from Dechow and Dichev’s (2002) model and from Dechow and Dichev (2002) as modified by McNichols’s (2002) model. The firms’ dividend policy is captured by dividend paying status. This is a dummy variable that takes the value of 1 if the firm pays dividends and 0 otherwise. In addition, dividend yield and dividend payout ratio, which are continuous variables, are also used in this paper as alternative proxies for dividend policy.

Using panel data analysis, this paper documents that dividend payers have higher earnings quality than dividend non-payers. Dividends are an indicator of earnings quality. These findings are consistent with prior studies. After controlling for variables that may be related to earnings quality as well as for the year and industry fixed effects, this relation remains unchanged. In addition, this result is also robust after controlling for firm fixed effects.

This paper offers the empirical evidence on the relation between dividend policy and earnings quality in Vietnam, which is a frontier market.

The malfunction variables of power stations are related to the areas of weather, physical structure, control and load behaviour. To predict temporal power failure is difficult due to their unpredictable characteristics. As high accuracy is normally required, the estimation of failures of short-term temporal prediction is highly difficult. This study presents a method for converting stochastic behaviour into a stable pattern, which can subsequently be used in a short-term estimator. For this conversion, K-means clustering is employed, followed by Long-Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) algorithms are used to perform the Short-term estimation. The environment, the operation and the generated signal factors are all simulated using mathematical models. Weather parameters and load samples have been collected as part of a data set. Monte-Carlo simulation using MATLAB programming has been used to conduct experimental estimation of failures. The estimated failures of the experiment are then compared with the actual system temporal failures and found to be in good match. Therefore, for any future power grid, there is a testbed ready to estimate the future failures.

In light of the COVID-19 pandemic, all business sectors have critical needs. They face multiple challenges to restructuring their operations to build a resilient, cost-effective and sustainable supply chain. Therefore, this paper aims to investigate the practice and the research gaps related to supply chains.

This research paper is influenced by a literature review of the past decade. This review paper incorporates industry challenges of the COVID-19 pandemic, including future steps toward developing resilient supply chains in the new normal economy. The research provides a detailed framework for designing cost-effective survivable supply chains that withstand disruptions for the long term.

The proposed research focuses on the effects of the COVID-19 pandemic on supply chains and attempts to bridge pre and post COVID-19 research and practice gaps. Post-COVID-19 resilient supply chains need to be transformed into survivable supply chains. The survivability of the supply chain can be achieved by combining both supply chain resilience and supply chain viability measures. To the best of the authors’ belief, this is the first study that grounds a theory to provide interconnection of five critical supply chain concepts to manage supply chain risk. This study is uniquely positioned to develop a theoretical framework to design a cost-effective, resilient and sustainable supply chain by establishing the interconnection among these concepts in supply chains. This framework helps practitioners to implement the key strategies at the operational, tactical and strategic levels that enhance maturity in supply chains.

The research findings are based on secondary reports such as industry reports, cases, research papers and expert opinions. The authors tried to consult with many companies. However, they were reluctant to share the recovery plan information from COVID. Also, as COVID still exists in many places in Canada, the authors could not gather every intended information from the companies. However, the authors have successfully shared the outcomes of this research with a reputed retail company in Canada. They recognized the importance of survivability in supply chains. Going forward, business organizations need to design cost-effective, sustainable and survivable supply chains.

The study attempts to unify current research dealing with supply chain resilience. The study concludes with the limitations of the current research. It highlights the prospects of future research and bridges the supply chain practice gaps from the challenges faced by industries due to COVID-19. The study contributes to the literature by identifying gaps to bridge the supply chain practice and reiterating new research directions to develop a cost-effective, survivable and sustainable supply chain.

The study examined the influence of relational capital on inter-cluster coordination and service delivery of humanitarian organisations; the mediating and moderating role of inter-cluster coordination on the relationship between relational capital and service delivery.

Data was collected from 60 humanitarian organisations. Potential respondents were five officers from each humanitarian organisation involved in delivering humanitarian assistance. Respondents from the different organisations were selected using purposive sampling. The SPSS software, SMART PLS and CB-SEM software were used to obtain results on the influence of relational capital on inter-cluster coordination and service delivery in humanitarian organisations; and the mediating and moderating role of inter-cluster coordination on the relationship between relational capital and service delivery.

Findings indicated that relational capital influences inter-cluster coordination and service delivery in humanitarian relief chains; inter-cluster coordination partially mediates the relationship between relational capital and service delivery in humanitarian relief chains; and no interactive effect was found when the moderation effect of inter-cluster coordination on the relationship between relational capital and service delivery in humanitarian organisations was examined.

The study was mainly focused on humanitarian organisations excluding beneficiaries and the logistics suppliers. The research has implications to decision-makers in government and humanitarian organisations concerned with providing relief aid to beneficiaries.

The influence of relational capital on inter-cluster coordination and service delivery in humanitarian relief chains; the mediating role and moderating role of inter-cluster coordination on the relationship between relational capital and service in humanitarian relief chains are aspects that have not been given significant attention empirically.

This study aims to improve understanding of how coastal maritime transport system of Vancouver Island would be disrupted in disaster events, and the strategies could be used to address such risks. Any transport disruption at the maritime leg of the supply chain can affect the needs of vulnerable residents and thus, the supply of many goods to coastal communities.

This case study focuses on the disruption that can be expected to occur for ferries that serves coastal communities of Vancouver Island in Canada. A landslide scenario in the Fraser River (which connects coastal communities) is developed, and interviews and focus groups are used to gain understanding of the vulnerability and resilience of shipping.

The findings show that the maritime leg of the supply chain for the coastal communities of Vancouver Island is resilient to a landslide disruption of ferries. Besides, there would be no impact on the operability of tugs and barges. This study also offers suggestions for creating the conditions for increasing resilience of maritime supply chains to any such disruption.

A research gap exists with respect to minimizing disruption in maritime supply chains, mainly in regard to lessening the impact on the vulnerable residents of coastal communities. This study contributes to filling this gap in the literature.

The findings have significant implications for maritime service providers and for people working on disaster preparedness, emergency response and recovery.

Studies which focus on alleviating the impact of disruptions in the maritime supply chains and the mitigation strategies for coastal communities are scarce in the literature.

The purpose of this paper is to present a family of robust metasurface-oriented wireless power transfer systems with improved efficiency and size compactness. The effect of geometric and structural features on the overall efficiency and miniaturisation is elaborately studied, while the presence of substrate losses is, also, considered. Moreover, to further enhance the performance, possible means for reducing the operating frequency, without comprising the unit-cell size, are proposed.

The key element of the design technique is the edge-coupled split-ring resonators patterned in various metasurface configurations and optimally placed to increase the total efficiency. To this goal, a rigorous three-dimensional algorithm, launching a new high-order prism macroelement, is developed in this paper for the fast evaluation of the required quantities. The featured scheme can host diverse approximation orders, while it is drastically more economical than existing methods. Hence, the demanding wireless power transfer systems are precisely modelled via reduced degrees of freedom, without the need to conduct large-scale simulations.

Numerical results, compared with measured data from fabricated prototypes, validate the design methodology and prove its competence to provide enhanced metasurface wireless power transfer systems. An assortment of optimized 3 x 3 and 5 x 5 metamaterial setups is investigated, and interesting deductions, regarding the impact of the inter-element gaps, the distance between the transmitting and receiving components and the substrate losses, are derived. Also, the proposed vector macroelement technique overwhelms typical implementations in terms of computational burden, particularly when combined with the relevant commercial software packages.

Systematic design of advanced real-world wireless power transfer structures through optimally selected metasurfaces with fully controllable electromagnetic properties is presented. The analysis is performed by means of a rapid prism macroelement methodology, which leads to very confined meshes, accurate results and significantly reduced overhead. The selected metamaterial resonators are found to be very flexible and reconfigurable, even in the case of large substrate conductivity losses, whereas their contribution to the system’s total efficiency is decisive.

The purpose of this study is to analyse the antecedent (Consumer Involvement) and the consequences (Brand Connection and Brand Usage Intent [BUI]) of the three dimensions of Consumer Brand Engagement (CBE) (Cognitive Processing, Affection and Activation) in luxury brand engagement on Facebook.

Data were collected through an online questionnaire completed by fans/followers of luxury brands’ Facebook pages. The empirical study was conducted using structural equation modelling.

Consumer Involvement has a positive impact on the three dimensions of CBE (Cognitive Processing, Affection and Activation). This leads to the conclusion that Activation and Affection have an impact both on Self-Brand Connection and on BUI. Moreover, it was found that Cognitive Processing impacts only on BUI.

The results identified the factors which brand managers should focus on to increase CBE on Facebook.

This study is a pioneer, as it extends the consumer engagement model to the social media context in a hedonic and conspicuous consumption category which includes luxury brand products.

Esta investigación analiza el antecedente (compromiso del consumidor) y las consecuencias (conexión con la marca e intención de uso de marca) de las tres dimensiones del compromiso del consumidor con la marca (procesamiento cognitivo, afectivo y activo) en el compromiso con la marca de lujo en Facebook.

Los datos se obtuvieron a través de un cuestionario online de los seguidores de varias páginas de marcas de lujo en Facebook. El estudio empírico se realizó utilizando un modelo SEM.

El compromiso del consumidor tiene un impacto positivo en las tres dimensiones del compromiso del consumidor con la marca (procesamiento cognitivo, afectivo y activo). Esto lleva a concluir que los procesos activo y afectivo tienen un impacto tanto en la conexión con la marca como en su intención de uso. Además, se constató que el proceso cognitivo sólo afecta a la intención de uso de la marca.

Los resultados identificaron los factores en los que los directores de marca deberían centrarse para aumentar el compromiso del consumidor hacia la marca en Facebook.

Este estudio es pionero, dado que extiende el modelo de compromiso del consumidor al contexto de las redes sociales en una categoría de consumo hedónico y ostentoso que incluye a bienes y servicios como las marcas de lujo.

By its very nature, the field of medical sociology has considerable potential for incorporating a consideration of gender in its research. After approximately a generation of the women's movement, women's studies, and the study of gender in sociology, now is an appropriate time to assess the impact of feminism on the mainstream of the field. Such an assessment is distinct from a feminist critique of medical sociology, with its implication that the field has many shortcomings, and also from a review of the growing sociological study of women's health (e.g., Auerbach and Figert 1995) and their role in providing as well as receiving care. Instead, my purpose is to examine representative research in mainstream medical sociology for evidence of the extent and nature of feminism's influence. Overall, I argue that by the 1990s mainstream medical sociology has been significantly affected by feminism, but that this effect is qualified in important ways.
