Abstract

The objective of this paper is to demonstrate how to use the Elton, Gruber, and Padberg [1978] model to construct optimal portfolios and to facilitate the use of this paradigm by providing an example of how the technique is used. The EGP model uses the risk‐adjusted, excess return for an asset to determine the optimal portfolio for a given risk‐free rate of return. This paper shows exactly how to calculate the optimal portfolio and provides a True Basic@ program to do so. The data used are constructed from Capital International Indexes taken from various issues of Barrons from March 1978 to December 1986.

Abstract

Purpose

The purpose of this paper is to obtain an insight into the effects of sliding and/or joint opening at the contraction, perimeter and concrete lift joints on the nonlinear seismic response of arch dams.

Design/methodology/approach

The seismic behavior of a typical thin double curvature arch dam is studied by a nonlinear finite element program developed by the authors. Joints are modeled with the use of zero thickness interface elements. Various constitutive relationships are implemented to account for sliding and opening along the joints. Effects of joint sliding parameters and foundation rock flexibility are also considered in the analyses.

Findings

The findings provide information about dynamic stress distribution through the dam body and stability of the dam as a whole and also the local stability of the most critical concrete blocks in the dam body.

Practical implications

Useful information for designing new arch dams or seismic evaluation of constructed dams.

Originality/value

This paper takes into account the stability of concrete blocks in the dam body as well as stability of the structure as a whole. Except for contraction joints, perimeter and concrete lift joints are also modeled. Practical as well as detailed models of sliding are provided for the analyses. The paper offers practical help to design and dam engineers.

Abstract

Purpose

According to data released by the Brazilian Institute of Geography and Statistics (Ernst & Young, 2010), the Brazilian middle class is represented by approximately 100 million people. Moreover, according to the Brazilian Association of Importers and Manufactures of Motor Vehicle Companies (ABEIFA, 2015), Brazil was ranked fourth in the world in the ranking of major automobile consumers. This is undoubtedly a highly attractive market for world producers in this sector. However, the Brazilian automobile market has some specific features that require a very prudent operation. This case aims to investigate how those idiosyncrasies were approached by the Chinese car manufacturer JAC Motors, which in addition to not having previous experience in that market, also presented a negative country of origin image.

Methodology/approach

We rely on a case study method to better understand how the executives of this Chinese firm approached the Brazilian market.

Findings

Pulling and pushing factors are the basis of the adaptation process followed by the car manufacturer to better serve the identified idiosyncrasies. It was not only China that pushed JAC Motors to go abroad, but also Brazil that attracted (pulled) the car manufacturer’s investment. Additionally, there is evidence of pushing factors on the side of JAC’s strategy and pulling factors on the side of a Brazilian partner.

Research limitations/implications

Internationalisation decision-making processes often result from a combination of factors which gain a specific ‘momentum’ that result in an extraordinary occasion that provides a unique opportunity to invest abroad.

Originality/value

The uniqueness of the opportunity to invest abroad is the result of the alignment of pulling and pushing factors, in the country, the company and at the decision-making level.

Abstract

Considers how the rights of children, protected under the Constitution of the Republic of South Africa and its Bill of Rights, can be reconciled with the effects of heavy fines, asset forfeiture and confiscation orders on economic offenders. Clarifies the concepts of forfeiture and confiscation. Outlines the 1998 Prevention of Organised Crime Act (POCA) and considers its provisions in relation to the position of children and young people as innocent third parties in cases of civil and criminal asset forfeiture. Includes a short discussion of corresponding provisions in US law. Suggests that, as legislation currently does not specifically provide for children, the POCA should be amended by incorporating, mutatis mutandis, provisions from the Mediation in Certain Divorce Matters Act.

Abstract

Purpose

To develop an in‐pipe robot to be used for inspecting pipes that are laid underneath a waste disposal site and for sampling sewage water leaking from holes around the pipe.

Design/methodology/approach

The paper presents a compact design of the robot's mechanical and electronic systems, and develops a simple and practical method for determining the hole position using some characteristics of this in‐pipe robot.

Findings

Development of a multi‐functional in‐pipe robot with elaborate design is feasible, and multiple trapezoidal‐shaped wheels have good capabilities of providing the robot large traction force and keeping the robot horizontal in pipeline. A good mechanical structure design can greatly reduce control and computation cost by using some specific features of the object system.

Research limitations/implications

This study provides guidance for future design of multi‐functional in‐pipe robots.

Practical implications

The combination of a vision system and a manipulator can perform in‐pipe inspection and other different tasks. The developed robot has already been used practically by a large Japanese construction company for pipe inspection and sewage sampling.

Originality/value

An in‐pipe robot is developed that cannot only implement pipe inspection, but which can also take sewage water samples. Most of such multiple‐functional small robots are still in development and rarely reported.

Abstract

Explains why and how lawyers become involved in money laundering schemes. Describes three recent cases of UK solicitors convicted for money laundering ‐ Denis Jebb, Louis Glatt and Noel Horner ‐ and notes that US lawyers are convicted more often than in the UK; this is possibly because in the USA there are more sting operations, phone intercepts, use of accomplice evidence, and a different exercise of prosecutorial discretion. Moves on to the services that lawyers provide launderers: advice, use of client accounts, purchase or sale of property, creation of corporate vehicles and trusts, lawyer ‐ client privilege, guarantees, introductions, powers of attorney, and false legal documentation. Discusses next the low level of disclosures by solicitors in the UK of suspicious transactions; reasons may be the general culture of non‐suspicion, the duty of client confidentiality, and confusion over laundering and tax evasion. Outlines new UK money laundering offences, which are likely to lead to an increase in the numbers of solicitor prosecutions.

Abstract

The Concept of Stability and Types of Instability THE term stable or unstable is applied to a body or system in accordance with the nature of the ultimate consequence of applying a disturbance. If the body or system is at rest and in equilibrium in a certain configuration, that configuration is said to be completely stable if the system ultimately comes to rest in the same configuration after the imposition of any disturbance. Frequently interest is confined to small disturbances; the term small is vague but must be interpreted as meaning that the motions of disturbance (or deviations) are so bounded that they can be described by linear differential equations. When this is so, the investigation of the stability becomes relatively easy and the actual magnitudes of the initial disturbances are not required in the discussion of the stability. The same concept of stability for small disturbances can obviously be applied to any steady motion and indeed to any regular motion. The criterion for stability is that the deviations from the basic motion consequent upon a small disturbance shall ultimately become vanishingly small.

Abstract

Purpose

The purpose of this paper is to examine multi-stakeholder cooperatives (MSCs), a relatively new and understudied type of cooperative, by focusing on the impact of a new member status: the “supporting member.” Supporting members are included in the ownership structure, participate in the decision-making process and contribute to the share capital without being formally defined as users of the cooperative’s services, an important disruption to the traditional cooperative venture.

Design/methodology/approach

This paper is based on a qualitative study using in-depth interviews with 30 members (i.e. founders, managers, board members and employees) of 14 MSCs located in the Canadian province of Québec.

Findings

This study suggests that including supporting members in the cooperative venture impacts the three core features of cooperatives, which are traditionally user-owned, user-controlled and user-benefiting. Despite supporting members’ positive contributions to an MSC’s development and success, the inclusion of such members generates management challenges and organizational paradoxes.

Social implications

The inclusion of supporting members allows MSCs to become an experiment in “stakeholder democracy” and a space of negotiation between organizations, citizens and institutions, as MSCs represent and embody some of the community’s needs and desires.

Originality/value

This study constitutes an original contribution to paradox literature, as it describes the specific upward and downward spirals related to the inclusion of supporting members, highlights innovative responses to these paradoxes and extends understandings of cooperatives as hybrid organizations entangled in bundles of paradoxes.

Abstract

Gives a bibliographical review of the finite element methods (FEMs) applied for the linear and nonlinear, static and dynamic analyses of basic structural elements from the theoretical as well as practical points of view. The range of applications of FEMs in this area is wide and cannot be presented in a single paper; therefore aims to give the reader an encyclopaedic view on the subject. The bibliography at the end of the paper contains 2,025 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1992‐1995.
