The socio-economic system underpinning apartheid in South Africa was based on the exploitation of black workers in the mines, the factories, the fields and the shops. It is widely recognized that the struggles of the South African black working class contributed decisively to the overthrow of the racist regime. In recognition of the power of organised labour, the democratic government elected in 1994 granted South Africa's unions unprecedented legal and constitutional rights. However, despite these gains, the country's labour movement has been facing a fresh set of challenges, from macroeconomic policy to the factory floor, many of them emanating from labour’s political allies in Government. The purpose of this book is to examine how the South African labour movement is responding to these challenges in the new millennium. A variety of experts on South African labour, both within the country and outside deal with crucial issues: How has South Africa's labour movement reacted to the ANC Government's neoliberal economic agenda? How do the unions relate to an increasingly diversifying, “flexible” and vulnerable workforce? What are labour’s prospects of contributing to a left project in democratic South Africa? What are the challenges facing the unions in relation to new forms of militancy and social movements?

This paper reports the results of a survey of north Queensland landholder attitudes with respect to a number of issues relating to participation in forestry. The survey explored the reasons why landholders plant trees, perceived obstacles to greater farm forestry, and attitudes to tree planting programs such as the Community Rainforest Reforestation Program (CRRP) and Private Joint Venture Scheme (PJVS). The results of the survey are discussed in the context of possible policy prescriptions that can be made at local, state and federal government levels to facilitate greater tree planting in the region. Many of the problems faced by local landholders are shared by landholders in other parts of Australia and throughout the world. This survey can thus serve as a case study, providing information on a number of issues concerning small-scale forestry policies that are of general relevance to the development of farm forestry programs.

La presente Tesi ha per oggetto lo sviluppo e la validazione di nuovi criteri per la verifica a fatica multiassiale di componenti strutturali metallici . In particolare, i nuovi criteri formulati risultano applicabili a componenti metallici, soggetti ad un’ampia gamma di configurazioni di carico: carichi multiassiali variabili nel tempo, in modo ciclico e random, per alto e basso/medio numero di cicli di carico. Tali criteri costituiscono un utile strumento nell’ambito della valutazione della resistenza/vita a fatica di elementi strutturali metallici, essendo di semplice implementazione, e richiedendo tempi di calcolo piuttosto modesti. Nel primo Capitolo vengono presentate le problematiche relative alla fatica multiassiale, introducendo alcuni aspetti teorici utili a descrivere il meccanismo di danneggiamento a fatica (propagazione della fessura e frattura finale) di componenti strutturali metallici soggetti a carichi variabili nel tempo. Vengono poi presentati i diversi approcci disponibili in letteratura per la verifica a fatica multiassiale di tali componenti, con particolare attenzione all'approccio del piano critico. Infine, vengono definite le grandezze ingegneristiche correlate al piano critico, utilizzate nella progettazione a fatica in presenza di carichi multiassiali ciclici per alto e basso/medio numero di cicli di carico. Il secondo Capitolo è dedicato allo sviluppo di un nuovo criterio per la valutazione della resistenza a fatica di elementi strutturali metallici soggetti a carichi multiassiali ciclici e alto numero di cicli. Il criterio risulta basato sull'approccio del piano critico ed è formulato in termini di tensioni. Lo sviluppo del criterio viene affrontato intervenendo in modo significativo su una precedente formulazione proposta da Carpinteri e collaboratori nel 2011. In particolare, il primo intervento riguarda la determinazione della giacitura del piano critico: nuove espressioni dell'angolo che lega la giacitura del piano critico a quella del piano di frattura vengono implementate nell'algoritmo del criterio. Il secondo intervento è relativo alla definizione dell'ampiezza della tensione tangenziale e un nuovo metodo, noto come Prismatic Hull (PH) method (di Araújo e collaboratori), viene implementato nell'algoritmo. L'affidabilità del criterio viene poi verificata impiegando numerosi dati di prove sperimentali disponibili in letteratura. Nel terzo Capitolo viene proposto un criterio di nuova formulazione per la valutazione della vita a fatica di elementi strutturali metallici soggetti a carichi multiassiali ciclici e basso/medio numero di cicli. Il criterio risulta basato sull'approccio del piano critico, ed è formulato in termini di deformazioni. In particolare, la formulazione proposta trae spunto, come impostazione generale, dal criterio di fatica multiassiale in regime di alto numero di cicli discusso nel secondo Capitolo. Poiché in presenza di deformazioni plastiche significative (come quelle caratterizzanti la fatica per basso/medio numero di cicli di carico) è necessario conoscere il valore del coefficiente efficace di Poisson del materiale, vengono impiegate tre differenti strategie. In particolare, tale coefficiente viene calcolato sia per via analitica, che per via numerica, che impiegando un valore costante frequentemente adottato in letteratura. Successivamente, per validarne l'affidabilità vengono impiegati numerosi dati di prove sperimentali disponibili in letteratura; i risultati numerici sono ottenuti al variare del valore del coefficiente efficace di Poisson. Inoltre, al fine di considerare i significativi gradienti tensionali che si verificano in presenza di discontinuità geometriche, come gli intagli, il criterio viene anche esteso al caso dei componenti strutturali intagliati. Il criterio, riformulato implementando il concetto del volume di controllo proposto da Lazzarin e collaboratori, viene utilizzato per stimare la vita a fatica di provini con un severo intaglio a V, realizzati in lega di titanio grado 5. Il quarto Capitolo è rivolto allo sviluppo di un nuovo criterio per la valutazione del danno a fatica di elementi strutturali metallici soggetti a carichi multiassiali random e alto numero di cicli. Il criterio risulta basato sull'approccio del piano critico ed è formulato nel dominio della frequenza. Lo sviluppo del criterio viene affrontato intervenendo in modo significativo su una precedente formulazione proposta da Carpinteri e collaboratori nel 2014. In particolare, l’intervento riguarda la determinazione della giacitura del piano critico, e nuove espressioni dell'angolo che lega la giacitura del piano critico con quella del piano di frattura vengono implementate nell'algoritmo del criterio. Infine, l’affidabilità del criterio viene verificata impiegando numerosi dati di prove sperimentali disponibili in letteratura.

Purpose – The purpose of this paper is to explore the criminal workplace activities of both employers and employees in Ukrainian enterprises. It challenges traditional definitions of corruption and suggests that the practices that can be observed fit into the category of organised crime because of the country's economic framework. The paper also explores how the practices are partially a legacy of Soviet economic processes. Design/methodology/approach – A total of 700 household surveys were completed in three cities, Kyiv (where 450 surveys were completed), Uzhgorod (150) and Kharkiv (100). To complement these, approximately 25 in-depth interviews were undertaken with workers in each region. Furthermore, ethnographic observations and “kitchen table” interviews also played an important role in the research. Although the research was oriented towards those working in informal economies, business owners (both formal and informal) were also interviewed. Findings – As well as revealing the endemic nature of corruption in Ukrainian workplaces and the high levels of informal activity undertaken by workers, the research found that many people wish for their workplace to become more regulated. Research limitations/implications – Further interviews could have been carried out with state officials and in more locations. The implications are multiple but mainly they demonstrate the difficulty that those charged with economic reform in Ukraine must face. Originality/value – It is one of the first studies to explore these issues in Ukraine using a variety of research methods.

The purpose of this research has been to investigate the extent to which Lean techniques have been applied to indirect or White Collar activities within manufacturing operations. The work has been based on a systematic review of the literature and six UK based case studies. Both are described in the paper. The findings from this work include, for example, that there are few reports off the application of Lean in this context. The more substantive papers focus on NPI and Project Management, where as, Support and ‘Front Office’ activities are covered only briefly in ‘trade journal’ articles. These do demonstrate that Lean techniques can be applied successfully to non-production related activities, and there are significant opportunities for work in this area. However, the definition of Lean is evolving and practitioners do not share a common understanding of terminology. This may undermine their accuracy when reporting the application of Lean techniques.

Discrete event simulation of manufacturing systems has become widely accepted as an important tool to aid the design of such systems. Often, however, it is applied by practitioners in a manner which largely ignores an important element of industry; namely, the workforce. Workers are usually represented as simple resources, often with deterministic performance values. This approach ignores the potentially large effect that human performance variation can have on a system. A long-term data collection exercise is described with the aim of quantifying the performance variation of workers in a typical automotive assembly plant. The data are presented in a histogram form which is immediately usable in simulations to improve the accuracy of design assessment. The results show levels of skewness and range which are far larger than anticipated by current researchers and practitioners in the field.

Manufacturing system design is an ongoing activity within industry. Modelling tools based on Discrete Event Simulation are often used by practitioners during this design cycle. However, such tools do not adequately model the behaviour of 'direct' workers in manufacturing environments. There is an important need to expand the capability of modelling to include the relationships between human centred factors (demography, attitudes, beliefs, etc), their working environment (physical and organizational), and their subsequent performance in terms of productive routines. Therefore, this paper describes research that has formed a pilot modelling methodology that is an important first step in providing such a capability.

Presents a prototype modelling methodology that provides a generic approach to the creation of quantitative models of the relationships between a working environment, the direct workers and their subsequent performance. Once created for an organisation, such models can provide a prediction of how the behaviour of their workers will alter in response to changes in their working environment. The goal of this work is to improve the decision processes used in the design of the working environment. Through improving such processes, companies will gain better performance from their direct workers, and so improve business competitiveness. This paper first presents the need to model the behaviour of direct workers in manufacturing environments. To begin to address this need, a simplistic modelling framework is developed, and then this is expanded to provide a detailed modelling methodology. There then follows a description of an industrial evaluation of this methodology at Ford Motor Company. This modelling methodology has been assessed in this case study and has been found to be valid in this case. There are many challenges that this theme of research needs to address. The work described in this paper has made an important first step in this area, having gone some way to establishing a generic methodology and illustrating its potential value. Our future work will build on this foundation.

This paper explores the nature of the co-called ‘private equity business model’ (PEBM) and assesses its shortcomings, using the illustrative example of the role of private equity in structuring the finance and subsequent collapse of MG Rover, as the automotive industry has been a significant destination for private equity financing. The paper outlines the nature of the PEBM. It then details how the PEBM extracts value, before stressing how this can affect workers in a portfolio business. We argue that the emergence of the PEBM changes the basis of competitive rules in organizations and the running of erstwhile going concerns, necessitating a need for further regulation—particularly, how to secure wider stakeholder oversight without reducing the efficiency of PEBM concerns.

During the 1970s and 1980s, close linkages were established between unionists in Volkswagen's Uitenhage plant in South Africa and Wolfsburg in Germany. The ensuing relationship resulted in trade union internationalism and solidarity with South African workers in their struggle against apartheid. After the insertion of the South African plant into the global production networks of the company, a range of new pressures and challenges confronted the union in South Africa. This resulted in the mass dismissal in 2000. In an attempt to garner international support and solidarity, the dismissed workers tapped into existing structures with no success, illustrating the reconfiguration of trade union internationalism away from worker interests to those of the unions and company. © 2010 UALE.

The programme of research examines knowledge workers, their relationships with organisations, and perceptions of management practices through the development of a theoretical model and knowledge worker archetypes. Knowledge worker and non-knowledge worker archetypes were established through an analysis of the extant literature. After an exploratory study of knowledge workers in a small software development company the archetypes were refined to include occupational classification data and the findings from Study 1. The Knowledge Worker Characteristics Model (KWCM) was developed as a theoretical framework in order to analyse differences between the two archetypes within the IT sector. The KWCM comprises of the variables within the job characteristics model, creativity, goal orientation, identification and commitment. In Study 2, a global web based survey was conducted. There were insufficient non-knowledge worker responses and therefore a cluster analysis was conducted to interrogate the archetypes further. This demonstrated, unexpectedly, that that there were marked differences within the knowledge worker archetypes suggesting the need to granulate the archetype further. The theoretical framework and the archetypes were revised (as programmers and web developers) and the research study was refocused to examine occupational differences within knowledge work. Findings from Study 2 identified that there were significant differences between the archetypes in relation to the KWCM. 19 semi-structured interviews were conducted in Study 3 in order to deepen the analysis using qualitative data and to examine perceptions of people management practices. The findings from both studies demonstrate that there were significant differences between the two groups but also that job challenge, problem solving, intrinsic reward and team identification were of importance to both groups of knowledge workers. This thesis presents an examination of knowledge workers’ perceptions of work, organisations and people management practices in the granulation and differentiation of occupational archetypes.

Most studies on diversity and discrimination in the workplace have focused on 'visible' minorities such as gender or race, often neglecting the experiences of invisible minorities such as lesbian, gay, bisexual and transgender (LGBT) workers. In this paper we explore the practices of inclusion/exclusion of LGBTs in the workplace in Italian social cooperatives, which are specifically founded to create employment for people who are disadvantaged in the labour market. The study examines how organizations, which have an ethos focused on inclusion and mainly employ workers from specific social minority groups, manage the inclusion of LGBT workers. We also explore the experience of LGBT workers within these organizations. The paper reports that the culture of silence existing in the five organizations studied prevents LGBT employees from constructing a work identity which encompasses their sexual identity and prevents the organizations from achieving their aim of being fully inclusive workplaces. © 2013 British Academy of Management.

During the years 1890–1920, the public school education system established itself as the medium to transmit American values, knowledge and culture. This study described and explained why some individuals were destined to fail, and others succeed in America's public schools. The exploratory questions guiding this study were: What elements constitute society's perspective of whom it should educate during the years 1890–1920? What variables influenced society's perspective of whom it should educate during the years 1890–1920? ^ After explaining these issues, educators will then have a better understanding and awareness of why certain educational practices are currently implemented and will be able to critically evaluate which ones should be continued. The methodology chosen was historical. The approach for analyzing the data was coding. The information was coded in order to determine themes, concepts and ideas amongst the documents and as portrayed in the literature. The first step was to seek out patterns and then to write out words and phrases to represent these topics. Then, these phrases were attributed to networks. ^ The data indicated that public schools during this era were designed to conform and assimilate the new immigrants and factory workers in an efficient and standardized manner. Efficiency and standardization in production became the American way for government, commerce, personal, lives and the school. Many different approaches to education emerged during this time period, specifically those, which emphasized individuality; but only those, which paralleled the ideology of efficiency, standardization and conformity were adopted. Those students who were unable to conform to society's criteria for success were penalized in the classroom, on IQ examinations and national standardized exams. ^ This study was illuminative in that it explained the root cause as to why some individuals are meant to succeed while others are penalized in the classroom. Future studies connecting standardized assessments and learning styles are suggested. ^
