A better therapeutic alliance at the beginning of treatment for addictive behaviours has been found to prevent dropout. The purpose of this paper is to evaluate how the development of therapeutic alliance dimensions was associated with the dropout prevention.

A total of 23 participants presented a substance use disorder related to heroin or cocaine and were in three distinct treatment phases of a therapeutic community. Each participant filled in the therapeutic alliance measures once a week after mini-groups. A naturalistic prospective research design was used to collate 198 repeated alliance measures.

Participants who presented stable bond development at higher levels tended to stay in treatment, whereas those who developed stable bonds at lower levels tended to drop out. The goals and tasks dimension increased significantly across the phases and was not associated with dropout.

To prevent dropout, therapists should pay special attention to residents who manifest difficulties in establishing stable and secure bonds and not overestimate the impact of the goals and tasks alliance dimension, as it is not a failsafe indicator of treatment retention.

The alliance dimensions were differentiated (bond, goals and tasks) and studied throughout the treatment, pointing out the importance of therapeutic relationship dynamic variables to prevent dropout.

This study aims to investigate whether the influence of group cohesion on the outcomes depended on the levels of the therapeutic alliance.

Sixteen individuals with a substance use disorder who were undergoing treatment in a therapeutic community responded to therapeutic alliance, group cohesion, craving and outcomes measures after every therapeutic small group session for a period of six weeks. Data analysis was performed using hierarchical linear modeling.

Results indicate that the effect of group cohesion is stronger when there is a high therapeutic alliance between resident and therapist.

Even on group interventions, to enhance group cohesion effects on outcomes, therapists must foster higher therapeutic alliance levels. The findings point out the importance of studying the effect of common factors on outcomes.

The purpose of this research synthesis is to gather and integrate findings on Collaborative Planning Forecast and Replenishment (CPFR) as a business process and as a management practice; and to assemble quantitative evidence of its impact on supply chain (SC) performance.

The researchers independently conducted a systematic review of 629 abstracts and 47 full-text papers. Original keywords were applied to four key electronic databases for operations management and information systems. Rigorous and verifiable selection criteria governed inter-coders reliability, review of steps and exclusion of papers. Resource and dependency-based view of the firm, contingency research and maturity models informed the analysis.

There is not a single “blueprint” for CPFR. Competing models emphasize the need for “trust and confidence” and reliable data systems. The type of products, scope, spatial diversity and number of partners in the network are important contextual variables. Firm resources that are unique and advantages from multiple and reciprocal dependencies are powerful levers. There is no consensus on maturity model and on required investment in data and communication systems.

Practical implications are implementation related: cost-benefit analysis and simulations should precede full-scale collaboration. There is a consensus on starting CPFR small and expanding gradually.

This synthesis applies a rigorous review method and attempts to assemble the dispersed literature in one study, utilizing explanatory operations management and information systems theories.

Investigates the entry of Wal‐Mart in Brazil, and subsequent moves of established retailers and new entrants with data taken from secondary sources and interviews with executives. First, internationalization of Wal‐Mart and its entry are discussed, which caused an impact on Brazilian retailing by accelerating the concentration, automation and modernization of the industry. Competitive reactions were classified in four categories: neutralizing competitors actions, establishing competitive advantage, redefining markets, and changing ownership. It is argued that Wal‐Mart’s experience in Brazil could be an interesting source of learning for foreign retailers desirous of entering the Brazilian market as well as for local companies that need to remain competitive to survive.

The case study will encourage reflection on the challenges that organisations face in attracting, engaging and retaining knowledge workers that are critical to their performance and growth. It is set in the context of innovative, high-tech organisations whose success is heavily dependent on the performance of information technology (IT) professionals, a specialised and heavily demanded workforce.

The case study depicts the struggle of Manoel Almeida, Descomplica’s chief technology officer, to reverse the scenario of demotivation and high turnover among IT employees and to attract new talent. The case study addresses the themes of knowledge worker attraction, engagement and retention, with a focus on IT professionals.

This case study is designed for undergraduate and graduate education programmes/courses.

The purpose of this paper is to identify how a city as a brand discursively conceives and articulates relevant meanings in order to build its identity.

The study follows a discursive semiotic approach using content from the Visit.Rio website and posts from its Facebook page.

It was possible to organize the values and meanings that structure the Rio de Janeiro brand in the semiotic square. Narrative schemes that concretize the value proposition guided mainly by contemplation and experimentation situations were identified. The discursive construction of the Rio de Janeiro brand is primarily marked by the relation between nature and culture, where contrasting meanings are explored by the City Hall managers.

This study is limited to the analysis of the enunciator (Rio de Janeiro brand managers) in their process of creating and articulating the city’s meanings. Future research could investigate the enunciate (public) perspective.

Managers should consider the discursive approach since it provides a more holistic perspective on the brand-building process. The findings may contribute to the understanding, selection and articulation of the correct meanings that should be communicated to the public in order to make the city a relevant and desirable place to visit.

This paper is based on the concept of a brand as a set of discourses grounded by meanings that are culturally conceived, which, thus, presents itself as a different approach from the traditional one, especially in research on place branding.

In the last few years, environmental issues have become a matter of survival. In this sense, e-waste management is among the major problems since it may be a way of mitigating mineral depletion. In this context, the literature lacks e-waste supply chain studies that systematically map supply chain challenges and risks concerning material recovery.

Given this context, the authors' paper conducted a systematic literature review (SLR) to build a framework to identify the constructs of e-waste supply chain risk management.

The paper revealed the theoretical relationship between important variables to achieve e-waste supply chain risk management via a circular economy (CE) framework. These variables include reverse logistics (RL), closed-loop supply chains (CLSC), supply chain risk management, supply chain resilience and smart cities.

The literature contributions of this paper are as follows: (1) a complete list of the risks of the e-waste supply chains, (2) the techniques being used to identify, assess and mitigate e-waste supply chain risks and (3) the constructs that form the theoretical framework of e-waste supply chain risk management. In addition, the authors' results address important literature gaps identified by researchers and serve as a guide to implementation.

During the last few years there has been an increase of interest in work-based learning (WBL), which can be understood as a process of both developing workplace skills and promoting labor force productivity. This paper aims to map the scientific landscape related to WBL research worldwide.

combined bibliometrics and network analysis techniques to analyze data of scientific publications related to WBL indexed at the Web of Science (WoS) Core Collection.

results show an increase of publications over time: Education & Educational Research as the most frequent research area to which the articles were assigned, the UK and Australia as the main countries and Monash University (Australia) and Middlesex University (England) as the main organizations producing knowledge on WBL.

By offering a global scientific landscape of WBL research published so far, the authors aimed to contribute to future academic debates and studies in this field of knowledge.

The purpose of this work is to present a methodology that harnesses the computational power of multiple graphics processing units (GPUs) and hides the complexities of tuning GPU parameters from the users.

A methodology for auto-tuning OpenCL configuration parameters has been developed.

This described process helps simplify coding and generates a significant gain in time for each method execution.

Most authors develop their GPU applications for specific hardware configurations. In this work, a solution is offered to make the developed code portable to any GPU hardware.
