Abstract

Purpose

The purpose of this study is to extend a novel numerical method proposed by the first author, known as the dual mesh control domain method (DMCDM), for the solution of linear differential equations to the solution of nonlinear heat transfer and like problems in one and two dimensions.

Design/methodology/approach

In the DMCDM, a mesh of finite elements is used for the approximation of the variables and another mesh of control domains for the satisfaction of the governing equation. Both meshes fully cover the domain but the nodes of the finite element mesh are inside the mesh of control domains. The salient feature of the DMCDM is that the concept of duality (i.e. cause and effect) is used to impose boundary conditions. The method possesses some desirable attributes of the finite element method (FEM) and the finite volume method (FVM).

Findings

Numerical results show that he DMCDM is more accurate than the FVM for the same meshes used. Also, the DMCDM does not require the use of any ad hoc approaches that are routinely used in the FVM.

Originality/value

To the best of the authors’ knowledge, the idea presented in this work is original and novel that exploits the best features of the best competing methods (FEM and FVM). The concept of duality is used to apply gradient and mixed boundary conditions that FVM and its variant do not.

Abstract

Purpose

This paper examines communication strategies, organization, and tactics of the pharmaceutical firm Merck & Co., Inc., as corporate executives and staff faced the withdrawal from market of Vioxx, the company's most profitable product.

Design/methodology/approach

The paper explores decision methodology and criteria as Merck executives sought to communicate with their most important stakeholders during the most dangerous and critical period in the company's history.

Findings

As well prepared as Merck & Co. was for a product withdrawal, nothing could have prepared company officers for communicating on the scale, scope, and volume that this crisis would demand. The value of a well‐conceived crisis response plan is underscored, as well as a flexible, responsive organization. Among the more notable findings is that even large, well‐funded, experienced professionals may need to reconsider their organizational structure as they address a multi‐faceted, large‐scale problem. Issues include staffing, functional expertise, length of time on task, and strategic use of key resources.

Practical implications

A number of important lessons in communication strategy have emerged from the experience of withdrawing Vioxx from the market and defending the company against both litigation and continuing bad press. First, a crisis communication plan is essential. Their plan allowed Merck & Co. to identify key individuals to be involved, their roles and responsibilities. A second important lesson concerns persistence and a long‐term view, despite near‐term pressure for earnings performance. Overcoming plaintiffs‐bar litigation may take another five years. A third lesson involves identifying and measuring those issues which Merck stakeholders most needed to know in order to correct misconceptions. Finally, corporate officers recognized that they must have faith in their decisions and recognize the value of their employees (across the organization) in communicating the company's message.

Originality/value

This paper examines the pharmaceutical firm Merck & Co., Inc. and the withdrawal from market of Vioxx, the company's most profitable product.

Abstract

Purpose

This paper aims to evaluate whether the integration of smart specialization strategies (S3) into clusters significantly impacts their efficiency for countries that still do not implement this policy. This study tests three effects: whether the kind of policies envisaged through an S3 strategy impacts cluster’s efficiency; whether this impact changes with the technological intensity of the clusters; to determine which S3 is more suitable for sub-clusters at different levels of technological intensity.

Design/methodology/approach

The Mexican economy is taken as case of study because it has a proper classification of its industries intro Porter’s cluster’s definition but still does not adopt the S3 policy. Through data envelopment analysis (DEA), this study evaluates the cluster’s efficiency increment when variables representing the S3 elements are included.

Findings

The results show that strategies following the S3 had a significant impact in all clusters, but when clusters were classified by technological intensity, the impact on efficiency is higher in clusters in the medium low-tech group.

Practical implications

According to the results in the DEA, it can be concluded that these S3 strategies have the potential to increase the clusters’ productivity significantly. These results make convenient the adoption of the S3 policy by countries that already count with a properly cluster definition.

Originality/value

These findings contribute to the lack of studies that analyze the join implementation of S3 on clusters.

Abstract

Purpose – Previously we (Martinez & Lee, 2000) reviewed the empirical literature of the 20th century on the topic of immigration and crime. This chapter discusses developments in this body of scholarship that have occurred in subsequent years.

Methodology – This literature review covers recent empirical research associated with the emerging “immigration revitalization perspective.”

Findings – Recent research has become substantially more sophisticated in terms of analytical methods, including multivariate modeling and statistically grounded mapping techniques. But the conclusion remains largely the same. Contrary to the predictions of classic criminological theories and popular stereotypes, immigration generally does not increase crime and often suppresses it.

Practical implications – Our review of the literature challenges stereotypical views about immigrants and immigration as major causes of crime in the United States. Unfortunately, these erroneous views continue to inform public policies and should be reconsidered in light of empirical data.

Value – This chapter represents the first attempt to synthesize recent empirical work associated with the immigration revitalization perspective. It will be of value to immigration scholars and criminologists as well as general readers interested in the relationship between immigration and crime.

Abstract

Purpose

The purpose of this paper is threefold: first, to analyze the origins of Adelco in the context of the “Consumer Orientation Campaign” (Orientación Para El Consumidor, OPEC, in Spanish) promoted by the Ministry of Economy between 1978 and 1981; second, to describe the main characteristics of Adelco during its first years, especially its activities, structure and its international connections; finally, to contribute to the study of consumer organizations in Argentina and Latin America, where very little research has been done on the subject.

Design/methodology/approach

This article is organized into three sections. First, it outlines the deep transformations taking place in the Argentine economy during the military regime, highlighting particularly the variations in inflation rates and a series of inflation-related policies. It goes on to offer a brief overview of some new studies in consumer history in Argentina as well as an analysis of the Consumer Orientation campaign, promoted by Martínez de Hoz, the Minister of Economy from 1978 to 1981. Finally, it details the origins and key features of Adelco. For source material, this paper uses a qualitative approach, working with government documents, interviews and magazines. It also makes use of the Minutes of the Board of Directors Meeting of Adelco. At the same time, this paper contributes to current debates in the history of consumption.

Findings

This paper reaches two main conclusions. First, while Adelco may have presented itself as a non-government organization (NGO) linked to consumer interests and responsive to grass-roots pressures, it maintained a top-down structure with close ties to state policy. Second, Adelco was part of what Matthew Hilton has analyzed as a shift in the consumer movement of the last several decades: a change from collective action to individual choice.

Originality/value

The main value of the paper rests on three factors. First, it offers an insight into the origins of Adelco, the first consumer defense NGO in Argentina. Second, it studies sources that have never previously been analyzed, such as the Minutes of the Board of Directors meeting and personal interviews. Third, it shows the ties between the origins of Adelco and the consumer policy of the military government in Argentina.

Abstract

Indigenous education in New Mexico has a long and disappointing history, but with current movements in the reformation of a more equitable system, there is hope for a constitutionally sound and appropriate education for New Mexico's students. The purpose of this chapter is to provide a historical overview of the New Mexico Indian Education Act of 2003 and examine the scope of this state legislation in the 2018 court decision in Yazzie/Martinez vs. the State of New Mexico. This court ruling has directly affected schools and students in New Mexico. Specifically, there are legal and operational ramifications to school districts and implications for curricular and classroom decisions that address inequities in public education for vulnerable student populations. To provide context, I share my testimony as a witness in the legal proceedings. I also argue that curricular development opportunities in critical literacy and critical awareness for education practitioners will prove to be important responses to the findings of the lawsuit. I share findings from qualitative research on the implementation of the New Mexico Indian Education Act prior to the Yazzie/Martinez lawsuit and the resulting changes to the legislation resulting from the court findings.

Abstract

Purpose

This study aims to investigate how the inter-organizational learning (inter-OL) of small and medium enterprises (SMEs) promote intra-organizational learnings (intra-OL) and how inter- and intra-OL jointly promote organizational innovation in the Korean electronics industry. This study also examines the moderating effect of organizational dynamism.

Design/methodology/approach

A unique theoretical model shows how inter-OL promotes organizational innovation through intra-OL, knowledge flows and stocks. Data was collected from 201 SMEs in the Korean electronics industry and analyzed by structural equation modeling.

Findings

The findings show that inter-OL directly and indirectly influences innovation. Inter-OL promotes both knowledge flows and stocks, but the only feedforward flows influence innovation through knowledge stocks while feedback flows directly influence innovation. Additionally, the study finds an indirect effect of inter-OL on knowledge stocks and a strong direct effect on innovation when dynamism is high. Intra-OL activities fully mediate between inter-OL and innovation when dynamism is low.

Research limitations/implications

This study uses single informants to measure all constructs. Future studies should use multiple informants.

Practical implications

This study shows that OL in SMEs is shaped by internal processes and external collaborations. Maintaining a connection with various external knowledge sources and creating collaborative opportunities to share learning experiences is critical to innovation.

Originality/value

This study is the first to empirically examine the relationship between inter- and intra-OL activities within a conceptual framework. The study provides a strategic view of how to facilitate OL activities considering the degree of organizational dynamism.

Abstract

Purpose

The authors developed a lesson study innovation for bridging pre-service teachers' experiences in an early methods course and clinical experiences focusing on the development of technological pedagogical content knowledge (TPACK). The authors analyze one planning meeting by a lesson study team comprised of four pre-service teachers and one cooperating teacher. The purpose of this research was to determine the nature of documentation during the online planning meeting and how the cooperating teacher facilitated the documentation process.

Design/methodology/approach

The authors used Gueudet and Trouche's (2009) documentation framework to determine the way the lesson study team in our study used all the resources available to plan a lesson. They analyzed the video recordings of the meeting to examine the interplay between material, didactical and mathematical components during the discussions. The material components included the Teacher Desmos Activity Builder and the eTextbook. The didactical components included assessment, scaffolding, multiple representations and problem-solving activities. The mathematical components pertained to systems of linear equations and inequalities with two variables.

Findings

The authors’ findings show that the cooperating teacher performed an invariant set of actions for improving the research lesson and, also, gave recommendations about how to implement the lesson. In facilitating the planning discussions, the cooperating teacher made explicit the relationship between material, didactical and mathematical components. The authors’ work has implications for supporting the preparation of facilitators of online planning sessions during lesson study.

Research limitations/implications

The authors did not have access to the planning meeting where the PSTs created the draft of the research lesson. In addition, they are reporting the observations of only one online meeting.

Originality/value

The authors’ work has implications for supporting the preparation of facilitators of online planning sessions during lesson study.

Abstract

Purpose

The meaning of Industry 4.0 has started to be outlined for the construction industry, but there is still limited knowledge on the implications for the single-family wooden house building industry. The purpose of this paper is to expand the understanding of what the fourth industrial revolution implies for the single-family wooden house industry. The paper contributes with practitioners’ view of the content and meaning of a smart single-family wooden house factory.

Design/methodology/approach

An exploratory multiple case study was carried out at two Swedish single-family wooden house builders, combined with a traditional literature review.

Findings

As a result of a multiple case studies, the content and meaning of a smart single-family wooden house factory was elaborated on. In total, 15 components of a smart single-family wooden house factory were identified, of which 8 corresponded to the components of Industry 4.0 as described in other sectors.

Research limitations/implications

The study can be expanded to also include multi-family wooden house builders and other branches of the offsite wooden building industry.

Practical implications

Managers in the house-building industry who want to improve and strive for a smart single-family wooden house factory can learn from this study, get an insight of what other companies consider as important and how it relates to Industry 4.0.

Originality/value

To the best of the authors’ knowledge, this study is a first attempt to understand what Industry 4.0 mean and how it can be accomplished for the single-family wooden house offsite manufacturing industry.
