In an effort to stimulate more OM research into the design, control, and management of white-collar work systems, this paper provides a systematic review of disparate streams of research relevant to understanding white-collar work from an operations perspective. Our review classifies research according to its relevance to white-collar work at individual, team, and organizational levels. By examining the literature in the context of this framework, we identify gaps in our understanding of white-collar work that suggest promising research directions.

  • Pink Collar Work
    September 2017 Pink collar work Gender and the Ohio workplace Lea Kayali Introduction Women are an essential part of the Ohio and national workforce. However, men consistently earn more than women. We call this wage disparity the gender pay gap. Improving jobs and compensation for women will boost our economy and provide more opportunity and security to women and their families. Husbands, sons and fathers depend on the salaries of women in their lives. Equal pay concerns all of us. Analysts cite several reasons for the gender wage gap. These include discrimination, differential compensation for jobs that have historically attracted men and women, occupational choice, level of labor force participation, and hours of work. This report provides an overview of the job market women face and considers these variables and the effect they have on the gap. Women in the workforce: An overview Women are a little less than half (48 percent) of Ohio’s workers.1 Men are more likely both to be in the labor force (68 percent) than women (57 percent) and to be employed (65 vs. 57 percent). Women comprise a far higher share of part-time workers than men do. It’s hard for families with children to send all adults into the workforce full time, so the lower-paid parent often works part time to manage more of the parenting.

  • Slavery and Reparative Justice by Professor Sir Geoff Palmer British Slavery in the West Indies Was Chattel Slavery and Was Lega
    Slavery and Reparative Justice by Professor Sir Geoff Palmer British slavery in the West Indies was Chattel Slavery and was legal. This slavery was supported by a Slave Trade which was abolished in 1807. One important aspect of the abolition of the slave trade was that the powerful Scottish politician Henry Dundas proposed successfully in Parliament in 1792 that this trading in slaves should be “gradually” abolished. This prolonged the Slave Trade for another 15 years during which time about 630,000 African people were transported into slavery. There were about 800,000 British Slaves in the West Indies when slavery was finally abolished in 1838. About 30% of the slave plantations in the British West Indies were owned by Scots. There is now significant evidence of Scotland’s involvement in this slavery. It is worth noting that documents such as the Jamaica Telephone Directory contain a significant number of Scottish surnames. Many place names in Jamaica are Scottish in origin and the flags of Jamaica and Scotland are of the same design. The year 2007 was the 200 th anniversary of the abolition of the Slave Trade. Since this date there has been a significant growth in interest in this slavery. Evidence seems to suggest that many Scottish people were not aware of the extent to which Scotland was involved in the practice of British slavery in the West Indies. It is this ‘public interest’ that has induced institutions to adopt a more serious approach to the study of Chattel Slavery. This extends from schools to universities to national and international organisations.

  • Criteria for Promotion to the Rank of Teaching Professor Teaching
    Criteria for Promotion to the rank of Teaching Professor Teaching excellence beyond Senior Lecturer Since senior lecturers are required to stay current in their discipline and pedagogy, but not required to seek promotion to Teaching Professor, the evidence supporting promotion should go beyond the excellent teaching typically expected of a senior lecturer. To qualify as a Teaching Professor, the candidate must have a record of accomplishment that advances the teaching mission of Indiana University. The criteria for granting long-term contracts after a probationary period shall be analogous to the criteria for granting tenure, except that lecturers shall earn the right to a long-term contract on the basis of their excellence only in those responsibilities that may be assigned to them. Each school will establish procedures and specific criteria for review of individuals concerning the renewal of long-term contracts or their equivalent.1 Promotion to Senior Lecturer or higher is based on continued improvement in and demonstration of excellence in teaching or service, with at least satisfactory performance in the remaining area.2 The dossier should convincingly substantiate a case in accordance both with the criteria in the Indiana University Academic Handbook and with any approved unit promotion and tenure guidelines. Promotion to Teaching Professor is analogous to being promoted from Associate to Full Professor. While no specific distinctions are made between being promoted to Associate Professor, to Professor, to Senior Lecturer or to Teaching Professor, higher levels of promotion will expect greater demonstrated achievement— in merit and in impact. However, what indicates excellence—for example, in research for a person seeking promotion to associate professor—is quantitatively and qualitatively different from what is expected of a person seeking promotion to professor.3 Lecturers are academic appointees whose primary responsibility is teaching.

  • Special Rapporteur on Extreme Poverty and Human Rights
    Statement on Visit to the United Kingdom, by Professor Philip Alston, United Nations Special Rapporteur on extreme poverty and human rights London, 16 November 2018 Introduction The UK is the world’s fifth largest economy, it contains many areas of immense wealth, its capital is a leading centre of global finance, its entrepreneurs are innovative and agile, and despite the current political turmoil, it has a system of government that rightly remains the envy of much of the world. It thus seems patently unjust and contrary to British values that so many people are living in poverty. This is obvious to anyone who opens their eyes to see the immense growth in foodbanks and the queues waiting outside them, the people sleeping rough in the streets, the growth of homelessness, the sense of deep despair that leads even the Government to appoint a Minister for suicide prevention and civil society to report in depth on unheard of levels of loneliness and isolation. And local authorities, especially in England, which perform vital roles in providing a real social safety net have been gutted by a series of government policies. Libraries have closed in record numbers, community and youth centers have been shrunk and underfunded, public spaces and buildings including parks and recreation centers have been sold off. While the labour and housing markets provide the crucial backdrop, the focus of this report is on the contribution made by social security and related policies. The results? 14 million people, a fifth of the population, live in poverty. Four million of these are more than 50% below the poverty line,1 and 1.5 million are destitute, unable to afford basic essentials.2 The widely respected Institute for Fiscal Studies predicts a 7% rise in child poverty between 2015 and 2022, and various sources predict child poverty rates of as high as 40%.3 For almost one in every two children to be poor in twenty-first century Britain is not just a disgrace, but a social calamity and an economic disaster, all rolled into one.

    Understanding Historical Change: Rome HIST 1220.R21, Summer 2016 Adjunct Professor Matthew Keil, PhD TWR 9:00 AM – 12:00 PM Dealy Hall 202, Rose Hill Email: [email protected] [email protected] (preferred) Web: MagisterKeil.com Office Hours by appointment in Faculty Memorial Hall , 428D Course Overview and Scope Within the ever-fractious saga of European history, ancient Rome looms unchallenged as the continent’s greatest period of unity and stability. At its zenith in the second century AD, the Roman Empire stretched from Hadrian’s Wall in Northern England to the Euphrates River in Syria, and from the Black Sea in the East to the Atlantic Ocean in the West. So tremendous in fact was the achievement of Rome in creating and sustaining this enormous empire that the very notion of Rome has left an indelible mark on all subsequent nations which are bearers of Western civilization. European rulers as far apart in time as Charlemagne, Napoleon, and Hitler have all consciously sought to position their respective dominions in relation to the Roman exemplar, and indeed the historical precedent for this positioning was first laid by the immediate successors to Rome's empire, the "barbarian" tribes who laid it waste, yet who nevertheless often called themselves Romans; after them, and for most of its subsequent history, Europe has seen some form of the Holy Roman Empire. It was not just in Europe, however, but also on the continents of Africa and Asia that Roman subjects swore their obedience to a single political system, acquiesced to the jurisprudence of a single law-code, and sought entrance into a single, distinct cultural community, despite their own often deep linguistic, religious, and regional diversity.

After all, most of us self-identify as middle class, and members of the middle class observe every day how their work contributes to the economy, hear weekly how their spending is a leading indicator for economic prognosticators, and see every month how jobs numbers, which primarily reflect middle-class jobs, are taken as the key measure of how the economy is faring. And as growing income inequality has risen in the nation’s consciousness, the plight of the middle class has become a common topic in the press and policy circles. For most economists, however, the concepts of “middle class” or even inequal- ity have not had a prominent place in our thinking about how an economy grows. This, however, is beginning to change.

  • Testing a Theory of Modern Slavery
    Testing a Theory of Modern Slavery Kevin Bales1 Introduction It is a simple yet potent truth that slavery is a relationship between (at least) two people. Like other common and patterned relationships in human societies, slavery takes various forms and achieves certain ends. The ends or outcomes of slavery tend to be more similar across time and cultures, the forms less so. The different outcomes of slavery are exploitative in nature: appropriation of labor for productive activities resulting in economic gain, use of the enslaved person as an item of conspicuous consumption, sexual use of an enslaved person for pleasure and procreation, and the savings gained when paid servants or workers are replaced with unpaid and unfree workers. Any particular slave may fulfill one, several, or all of these outcomes for the slaveholder. While the outcomes of slavery tend to be similar, the forms of enslavement are more varied. There is a core of central attributes that define a relationship as slavery, but these attributes are embedded in a wide variety of forms reflecting cultural, religious, social, political, ethnic, commercial, and psychological influences and combinations of these influences. The mix of influences that dictate the form of any particular slave/slaveholder relationship may be unique, but follow general patterns reflective of the community and society in which that relationship exists. This is part of the challenge of understanding slavery both historically and today – to parse out the underlying attributes shared by all forms of slavery and to analyze and understand the dynamic and various forms slavery can take in individual cases.

  • Service Workers: Governmentality and Emotion Management
    Service Workers: Governmentality and Emotion Management By Hing Ai Yun Abstract That all may be quiet on the shop floor could be a result of governmentality pro- jects. But what lies beneath an appearance of professionalism? I undertook an empirical field study of workers in the service industry to examine contradictory and competing interests of employees and their employers and observed the dy- namic constitution of subjectivity in situations of conflict. Based on a study of 56 service workers, this study first looks at the consensual orientation of workers towards their employment, then discusses a number of common demands required of workers in the service sector and investigates how workers deal with these management demands. My investigation of service workers disclose the internal- ised struggles experienced in their commitment to a prescribed, official image while attempting to maintain, at the same time, an integrous sense of self. By col- lecting stories of actual situations, I am able to show how patterns of emotion management, effectiveness of governmentality project, and agency work together to shape social behaviour in working life. Keywords: Governmentality, emotion management, organismic emotion model Yun, Hing Ai: “Service Workers: Governmentality and Emotion Management”, Culture Unbound, Volume 2, 2010: 311–327. Hosted by Linköping University Electronic Press: http://www.cultureunbound.ep.liu.se Introduction During the 1980s, terms like “knowledge worker” were bandied about as part of euphoric predictions heralding the “new economy” (Ritzer 1989) and “post indus- trial capitalism” (Heydebrand 1989; Castells 1996). It was proclaimed that knowl- edge and organization, rather than physical capital, are motors of change.
