The transition from severe to mild wear in law alloy steel

The wear rates of sliding surfaces are significantly reduced if mild oxidational wear can be encouraged. It is hence of prime importance in the interest of component life and material conservation to understand the factors necessary to promote mild, oxidational wear, The present work investigates the fundamental mechanism of the running-in wear of BS EN 31!EN 8 steel couples. under various conditions of load. speed and test duration. Unidirectional sliding experiments were carried out on a pin-on~disc wear machine where frictional force, wear rate, temperature and contact resistance were continuously monitored during each test. Physical methods of analysis (x-ray, scanning electron microscopy etc.) were used to examine the wear debris and worn samples. The wear rate versus load curves revealed mild wear transitions, which under long duration of running, categorized mild wear into four distinct regions.α-Fe20s. Fe304, FeO and an oxide mixture were the predominant oxides in four regions of oxidational wear which were identified above the Welsh T2 transition. The wear curves were strongly effected by the speed and test duration. A surface model was used to calculate the surface parameters, and the results were found to be comparable with the experimentally observed parameters. Oxidation was responsible for the transition from severe to mild wear at a load corresponding to the Welsh T2 transition. In the running-in period sufficient energy input and surface hardness enabled oxide growth rate to increase and eventually exceeded the rate of removal, where mild wear ensued. A model was developed to predict the wear volume up to the transition. Remarkable agreement was found between the theoretical prediction and the experimentally-measured values. The oxidational mechanjsm responsible for transitjon to mild wear under equilibrium conditions was related to the formation of thick homogenous oxide plateaux on subsurface hardened layers, FeO was the oxide formed initially at the onset of mild wear but oxide type changed.during the total running period to give an equilibrium oxide whose nature depended on the loads applied.

Nations and organizations:a comparative study of English and Indian work-related attitudes and values in matched manufacturing firms

This thesis reports a cross-national study carried out in England and India in an attempt to clarify the association of certain cultural and non-cultural characteristics with people's work-related attitudes and values, and with the structure of their work organizations. Three perspectives are considered to be relevant to the objectives of the study. The contingency perspective suggests that a 'fit' between an organization's context and its structural arrangements will be fundamentally necessary for achieving success and survival. The political economy perspective argues for the determining role of the social and economic structures within which the organization operates. The culturalist perspective looks to cultural attitudes and values of organizational members for an explanation for their organization's structure. The empirical investigation was carried out in three stages in each of the two countries involved by means of surveys of cultural attitudes, work-related attitudes and organizational structures and systems. The cultural surveys suggested that Indian and English people were different from one another with regard to fear of, and respect and obedience to, their seniors, ability to cope with ambiguity, honesty, independence, expression of emotions, fatalism, reserve, and care for others; they were similar with regard to tolerance, friendliness, attitude to change, attitude to law, self-control and self-confidence, and attitude to social differentiation. The second stage of the study, involving the employees of fourteen organizations, found that the English ones perceived themselves to have more power at work, expressed more tolerance for ambiguity, and had different expectations from their job than did the Indian equivalents. The two samples were similar with respect to commitment to their company and trust in their colleagues. The findings also suggested that employees' occupations, education and age had some influences on their work-related attitudes. The final stage of the research was a study of structures, control systems, and reward and punishment policies of the same fourteen organizations which were matched almost completely on their contextual factors across the two countries. English and Indian organizations were found to be similar in terms of centralization, specialization, chief executive's span of control, height and management control strategies. English organizations, however, were far more formalized, spent more time on consultation and their managers delegated authority lower down the hierarchy than Indian organizations. The major finding of the study was the multiple association that cultural, national and contingency factors had with the structural characteristics of the organizations and with the work-related attitudes of their members. On the basis of this finding, a multi-perspective model for understanding organizational structures and systems is proposed in which the contributions made by contingency, political economy and cultural perspectives are recognized and incorporated.

Risk assessment applied to comsumer products with reference to CE marking machines for use at work

New Approach’ Directives now govern the health and safety of most products whether destined for workplace or domestic use. These Directives have been enacted into UK law by various specific legislation principally relating to work equipment, machinery and consumer products. This research investigates whether the risk assessment approach used to ensure the safety of machinery may be applied to consumer products. Crucially, consumer products are subject to the Consumer Protection Act (CPA) 1987, where there is no direct reference to “assessing risk”. This contrasts with the law governing the safety of products used in the workplace, where risk assessment underpins the approach. New Approach Directives are supported by European harmonised standards, and in the case of machinery, further supported by the risk assessment standard, EN 1050. The system regulating consumer product safety is discussed, its key elements identified and a graphical model produced. This model incorporates such matters as conformity assessment, the system of regulation, near miss and accident reporting. A key finding of the research is that New Approach Directives have a common feature of specifying essential performance requirements that provide a hazard prompt-list that can form the basis for a risk assessment (the hazard identification stage). Drawing upon 272 prosecution cases, and with thirty examples examined in detail, this research provides evidence that despite the high degree of regulation, unsafe consumer products still find their way onto the market. The research presents a number of risk assessment tools to help Trading Standards Officers (TSOs) prioritise their work at the initial inspection stage when dealing with subsequent enforcement action.

Institutional work taken literally: How logics shift as banking lawyers 'get the deal done'

The role of interest and agency in the creation and transformation of institutions, in particular the “paradox of embedded agency” (Seo & Creed, 2002) have long puzzled institutional scholars. Most recently, Lawrence and Suddaby (2006) coined the term “institutional work” to describe various strategies for creating, maintaining and disrupting institutions. This label, while useful to integrate existing research, highlights institutionalists’ lack of attention to work as actors’ everyday occupational tasks and activities. Thus, the objective of this study is to take institutional work literally and ask: How does practical work come to constitute institutional work? Drawing on concepts of “situated change” (Orlikowski, 1996) I supplement existing macro-level perspectives of change with a microscopic, practice-based alternative. I examine the everyday work of English and German banking lawyers in a global law firm. Located at the intersection of local laws, international financial markets, commercial logics and professional norms, banking lawyers’ work regularly bridges different normative settings. Hence, they must constructively negotiate contradictory meanings, practices and logics to develop shared routines that resonate with different normative frameworks and facilitate task accomplishment. Based on observation and interview data, the paper distils a process model of banking transac-tions that highlights the critical interfaces forcing English and German banking lawyers into cross-border sensemaking. It distinguishes two accounts of cross-border sensemaking: the “old story” in which contradictory practices and norms collide and the “new story” of a synthetic set of practices for collaboratively “editing” (Sahlin-Andersson, 1996) legal documentation. Data show how new practices gain shape and legitimacy over a series of dialectic contests unfolding at work and how, in turn, these contests shift institutional logics as lawyers ‘get the deal done’. These micro-mechanisms suggest that as practical and institutional work blend, everyday work-ing practices come to constitute a form of institutional agency that is situated, emergent, dialectic and, therefore, embedded.

Performance management and high performance work practices in emerging markets

In this chapter, we discuss performance management systems (PMSs) and high performance work systems (HPWSs) in emerging economies. We start by discussing PMSs, with specific emphasis on PMSs in global organizations. We follow this up with an introduction of HPWSs, and then discuss PMSs and HPWSs in emerging economies. While the list of emerging economies keeps changing, and is rather long, as one might expect, in this chapter we have concentrated on five key emerging economies – China, India, Mexico, South Korea, and Turkey. Performance management is the process through which organizations set goals, determine standards, assign and evaluate work, coach and give feedback, and distribute rewards (Fletcher, 2001). In this connection, organizations all over the world face the challenge of how best to manage performance, including finding ways to motivate employees to sustain high levels of performance. In other words, organizations must develop and implement PMSs that are appropriate for their environment in such a way that high levels of performance can be achieved and sustained over time (DeNisi, Varma and Budhwar, 2008). While all organizations need to address these issues, the way a firm decides to go about addressing these issues is dependent on its location and context. In other words, differences in local norms, culture, law, and technology, make it critical that organizations develop and/or adapt techniques, policies and practices that are appropriate to the setting (see for example, Hofstede, 1993).

The Central Agency for Jewish Education: Fifty years of Jewish education in Dade County

The purpose of the study was to provide a historical record of the Bureau of Jewish Education/Central Agency for Jewish Education and its role in Jewish education in Miami since its inception in 1944 as well as to provide a sociological context within which to view the growth and development of the community. During the past 50 years of the Agency's existence, Dade County's Jewish population has undergone many changes including a huge population increase in the 1960s and 1970s and then a decrease in the 1980s and 1990s, and a shift from postwar business class of store owners to turn of the century professional class.^ The methodology used in this study was threefold. First, document analysis of formal and informal documents dating from 1944 to the present was conducted. Second, personal interviews were conducted with the Executive Directors of the B.J.E./C.A.J.E., long-time B.J.E./C.A.J.E. staff, present staff, Greater Miami Jewish Federation leaders, and lay leadership of C.A.J.E. Third, national trends in Jewish education were cited as a basis for the comparison and contrast of the achievements of C.A.J.E.^ The historiography concluded that the Agency had come full circle in its programs. Analysis of the services provided to religious and day schools, early childhood education, the High Schools, teacher services, adult education, and the library indicated that in some areas C.A.J.E. was an innovator, in other areas it followed national trends, and in others it was deficient. Recommendations included a reeducative process for the community with Jewish education made top priority, more visibility and publicity for the work of C.A.J.E. that would enhance its prestige and improve support, and holistic planning of programs for the future. ^

La kabala dentro del discurso contemporaneo y urbano: El ejemplo de Marcos Ricardo Barnatan

This dissertation analyzes the relationship between several mystic Sephardic texts called the Kabalah which include the three basic mystic books of Judaism: Sefer Yetsira, Sefer Bahir, and Sefer Zohar, and Argentine writer of Jewish descent, Marcos Ricardo Barnatan’s experimental work. The premise is that several mystic Sephardic texts have certain literary characteristics that make them fertile sources for the inspiration of writers like Barnatan. This thesis proves that Barnatan’s poetry and his first novel El Laberinto De Sion both use the most general concepts of the Kabalah in developing his literary and artistic creations. ^ This study is focuses on the concept that there exists a possibility of reading kabalistic texts not only in an exegetical way, but also in a poetic way. Barnatan’s literature is prone to this kind of reading of the texts. He creates a surprisingly expressive structure without ties to established models. This expressive structure is built on a vast amount of symbols, which results from this freedom. Barnatan adopts multiple symbols from cosmogenic theories and makes use of them, thus incorporating both the spirit and style of kabalistic texts into his own work. ^ Instead of addressing some of the main concerns of Kabbalistic study and its commentary, Barnatan avoids the concern for Law, the study of the Torah and its commentaries, while avoiding the use of the Hebrew language. For this reason Barnatan is too deviant to be considered an extension from the mainstream Kabbalistic commentary. Barnatan’s work is destined for a reader who cannot only understand his experimental methods, but who can also assemble a disjointed text while accepting a fundamental instability of space and time.^

Appraising Work Group Performance: New Productivity Opportunities in Hospitality Management

In - Appraising Work Group Performance: New Productivity Opportunities in Hospitality Management – a discussion by Mark R. Edwards, Associate Professor, College of Engineering, Arizona State University and Leslie Edwards Cummings, Assistant Professor, College of Hotel Administration University of Nevada, Las Vegas; the authors initially provide: “Employee group performance variation accounts for a significant portion of the degree of productivity in the hotel, motel, and food service sectors of the hospitality industry. The authors discuss TEAMSG, a microcomputer based approach to appraising and interpreting group performance. TEAMSG appraisal allows an organization to profile and to evaluate groups, facilitating the targeting of training and development decisions and interventions, as well as the more equitable distribution of organizational rewards.” “The caliber of employee group performance is a major determinant in an organization's productivity and success within the hotel and food service industries,” Edwards and Cummings say. “Gaining accurate information about the quality of performance of such groups as organizational divisions, individual functional departments, or work groups can be as enlightening...” the authors further reveal. This perspective is especially important not only for strategic human resources planning purposes, but also for diagnosing development needs and for differentially distributing organizational rewards.” The authors will have you know, employee requirements in an unpredictable environment, which is what the hospitality industry largely is, are difficult to quantify. In an effort to measure elements of performance Edwards and Cummings look to TEAMSG, which is an acronym for Team Evaluation and Management System for Groups. They develop the concept. In discussing background for employees, Edwards and Cummings point-out that employees - at the individual level - must often possess and exercise varied skills. In group circumstances employees often work at locations outside of, or move from corporate unit-to-unit, as in the case of a project team. Being able to transcend individual-to-group mentality is imperative. “A solution which addresses the frustration and lack of motivation on the part of the employee is to coach, develop, appraise, and reward employees on the basis of group achievement,” say the authors. “An appraisal, effectively developed and interpreted, has at least three functions,” Edwards and Cummings suggest, and go on to define them. The authors do place a great emphasis on rewards and interventions to bolster the assertion set forth in their thesis statement. Edwards and Cummings warn that individual agendas can threaten, erode, and undermine group performance; there is no - I - in TEAM.

Generational Differences in Work Attitudes: Evidence from the Hospitality Industry

Our understanding of employee attitudes and their impact on business outcomes has been further complicated in recent years by the newest cohort of service workers. Known as Generation Y (Gen Y), they appear to approach employment in a manner different to that of their predecessors. A review of the academic literature reveals little empirical evidence to support an appropriate understanding of the impact of such difference. This paper provides an overview of a large-scale study into generational differences in employee attitudes and reports on the preliminary data analysis of a survey of over 900 hospitality employees. The most important initial finding from the data analysis is that, on the whole, Gen Y employees have lower scores on those constructs that an organization should be attempting to maximize. Non-Gen Y employees are more satisfied with their jobs, more engaged and more affectively committed to the organization they work for than their Gen Y counterparts, amongst a range of other important constructs. Conversely, Gen Y employees display higher scores onthe constructs that an organization would want to minimize in its staff. Gen Y employees are more likely to be planning to quit their jobs, are more likely to perform poorly if their co-workers are doing so, and are also more likely to switch jobs for no particular reason. The discussion covers implications for management as well as directions for future research.

Can the Quilombo Model of Collective Land Titling Work in Rio’s Favelas?

Due to their informality, the favelas of Rio de Janeiro are in a precarious position. Though the informal neighborhoods have long served as sites of affordable housing for Rio’s poorest residents, changes within in the city related to public security, mega-events, real estate speculation, and urban revitalization jeopardize their permanence. As one possible solution, this study, conducted for the client Catalytic Communities, investigated collective titling in favelas modeled after quilombos, territories recognized and titled by Brazilian federal law as patrimonies of black cultural traditions.
