Abstract

Purpose

Conversion of the correlated random variables into independent variables, especially into independent standard normal variables, is the common technology for estimating the statistical moments of response and evaluating reliability of random system, in which calculating the equivalent correlation coefficient is an important component. The purpose of this paper is to investigate an accurate, efficient and easy to implement estimation method for the equivalent correlation coefficient of various incomplete probability systems.

Design/methodology/approach

First, an approach based on the Mehler’s formula for evaluating the equivalent correlation coefficient is introduced, then, by combining with polynomial normal transformations, this approach is improved to be valid for various incomplete probability systems, which is named as the direct method. Next, with the convenient linear reference variables for eight frequently used random variables and the approximation of the Rosenblatt transformation introduced, a further improved implementation without iteration process is developed, which is named as the simplified method. Finally, several examples are investigated to verify the characteristics of the proposed methods.

Findings

The results of the examples in this paper show that both the proposed two methods are of high accuracy, by comparison, the proposed simplified method is more effective and convenient.

Originality/value

Based on the Mehler’s formula, two practical implementations for evaluating the equivalent correlation coefficient are proposed, which are accurate, efficient, easy to implement and valid for various incomplete probability systems.

Abstract

Purpose

The purpose of this paper is to show how one of the biggest phenomena of the twenty‐first century is the internationalisation of professional sports and how premier league football epitomises this. With the influx of foreign players, managers and now owners, European League Football has become big business. This paper aims to provide a theoretical analysis of the management implications of foreign players in the English Premiership League football – renamed the Barclays Premier League to suit the needs of its major sponsors.

Design/methodology/approach

The approach adopted is purely qualitative in nature, evaluating the top Barclays Premier League teams and the impact of globalisation on their reconfigurations since the early 1990s to date. The study draws mainly from a review of the extant literature on sports and management, as well as a critical analysis of media reports.

Findings

Globalisation has emerged as a new force that has changed the way corporations are managed. Financial services, retail and information technology firms have all responded to this new wave – and so also has sports. Unfortunately while sports have the potential to teach lessons on management strategy, management researchers seem to have relegated sports to the sociology and psychology disciplines.

Practical implications

The Barclays Premier league football provides a unique environment for management decisions and processes to occur in a range of markets and at varied levels. However, the globalisation of professional sports has received relatively very little attention in the academic literature – especially in the field of business and management.

Originality/value

This paper contributes to the scant literature on the management implications of football by highlighting how globalisation has affected and reconfigured professional sports using the influx of foreign players into the English football league as a point of departure.

Abstract

Purpose

The purpose of this paper is to highlight the challenges of Nigerian Professional Football League teams at the club level, with a view to aligning this with developments at the country level, and especially so in the aftermath of the 2014 FIFA World Cup in Brazil – an international event – where Nigeria participated alongside four others – Algeria, Cameroon, Ghana and Ivory Coast.

Design/methodology/approach

The meta-analysis adopts a qualitative research approach, drawing upon a review of secondary data sources and the observation technique.

Findings

Although Nigeria’s first team players ply their trade in Europe, there remains a challenge epitomised by the “disconnect” between the domestic league and the national team composition. As a consequence, brand ambassadors are proposed as one of the key conduits for re-aligning the identified disconnect.

Research limitations/implications

The dual focus on club level and a single country – albeit in the light of Nigeria, former African champions, poses a limitation as the domestic league in that country may not be representative of others across the continent. However, some insight is also derived from developments in another African football giant – i.e. Ghana, runners-up of the recently concluded 2015 African Nations Cup.

Practical implications

In the long history of the FIFA Football World Cup, only three African teams have ever reached the quarter-finals – notably Cameroon in 1990, Senegal in 2002 and Ghana in 2010. Although the Super Eagles relished the label of African Champions going in the World Cup finals, they remain incapacitated, having failed to “fly” into the round of 16 since their 1994 debut. Furthermore, the alignment at the micro or club level to the meso or country level remains to be investigated at both scholarly and policy levels.

Social implications

There are success stories on the management and development of football in Africa and as the case of Nigeria demonstrates, Stephen Keshi, the national coach, symbolises missed opportunities – i.e. brand ambassadors – to increase visibility and engagement with the domestic league.

Originality/value

This is one of the very few studies that have sought to highlight the misalignment between club and country within the research context of Africa. It is also one of the few papers that have called on the need for brand ambassadors as a means of bridging the gap in this area.
