This paper focuses on the views of Human Resource (HR) managers about the implementation of work life balance (WLB) initiatives. Increasingly, WLB has become an important part of employment relations discussion and knowledge. The literature presents two key themes in terms of how this is implemented in practice. Firstly there was a corporate theme, where WLB is developed and applied from within the organisation. In the second theme WLB is developed and applied in tripartite partnership. The literature showed the New Zealand (NZ) experience is confused as to which path it is following. Thus, the purpose of this study was to explore the views of HR managers in NZ government funded tertiary institutions about the implementation of WLB practices. The research involved 3 in-depth, semi-structured interviews, which were then transcribed, analysed and compared until stable categories emerged. The findings reflected the confusion found in the literature. Approaches and knowledge of WLB were standardised and essentially uniform; there was much pride and satisfaction in achievements, both individual and corporately: and despite being government funded, the organisations reflected a corporatist theme in their approach to WLB. In summary, regardless of the rhetoric of WLB as positive to workers regaining balance in their lives, the research showed in practice it was 'a wolf in sheep's clothing' -- more beneficial for the organisations in terms of increasing worker productivity, than for the workers.

What scholars are committed to in principle is not always what they are likely to uphold in practice. Adam T. Smith examines – and deplores – the striking discrepancy between the centrality of the constructivist idiom in a variety of disciplines and the tendency of archaeologists to continue to treat archaeological subjects (be they ethnic groups, classes, nations, races, cultures or any other kind of identity group) as given entities and stable units of analysis. Smith's concern is not merely about the consistency of the discipline's theoretical underpinnings. In fact, his greatest worry turns out to be political: an archaeology that reconstitutes, rather than deconstructs, the essential subject may be wrongly used as a foundation for contemporary political action (such as nationalism). Thus he invites archaeologists to revise the relationship between scholarly analysis and political practice. Smith not only suggests taking into full account the malleability of identity groups in relation to changing sociopolitical contexts, but he also incites scholars to bend their minds to the sociopolitical circumstances within which seemingly stable categories of identity are produced. Archaeologists should be careful not to ‘essentialize’ identities, he concludes, but instead shift their attention to exposing the strategic practices deployed by those who do ‘essentialize’ identities.


In 20th-century Mexico, as in many other places, consumer culture and mass media have shaped everyday experiences, helped give meaning to ordinary lives, and opened up spaces in which political ideologies could be created and contested. Cultural forms such as dance, song, cuisine, clothing, and sports have been deployed to distinguish regions from one another, while at the same time, print media, radio, television, recorded music, film, and other cultural forms have connected Mexicans across regional and international borders (and across lines of gender, class, ethnicity, language, religion, political affiliation, and more) from the 1880s to the present day. Consumer culture—meaning the distribution, sale, and use of mass-produced goods such as clothing, as well as agricultural commodities like sugar and coffee—linked Mexico to a wider world in the historical era in which Mexico joined in the global process of rapid-fire modernization. The study of mass media and consumer culture in Mexico has been, at its best, highly interdisciplinary: historians and art historians, literary critics and cinema studies specialists, sociologists, and ethnographers have worked with journalists, folklorists, ethnomusicologists, and others in developing a sophisticated scholarly literature. This literature has its roots in two interrelated schools of scholarship: one that interpreted the products of culture industries as well as the creativity of ordinary people in a search for clues to Mexican national identity, and another that interpreted both locally made and imported mass media to understand how they shaped and supported the political, social, and economic status quo, both locally and globally. Since the 1980s, however, scholarly attention has broadened its focus from the images, narratives, movements, sounds, and objects produced by Mexican and foreign culture industries, and recent scholarship has looked to processes of creation, distribution, criticism, and consumption as well. Identities—whether regional, national, local, ideological, sexual, or political—are no longer understood as stable categories, but rather as a highly contested set of ideas, stories, and pictures that have changed radically over time. Much scholarship on mass media and consumer culture now begins with the understanding that culture industries have provided the tools with which discourses of identity could be shaped and reshaped, and that audiences and consumers have sometimes picked up those tools and turned them to their own purposes. And they have moved beyond taking the nation as a central category of analysis to ask how Mexican consumers and culture industries have participated in international and transnational processes of modernization.

In addition to assessing the hygienic customs of Indigenous people, these sources catalogued visual clues defining who were graced or damned according to Calvinists’ predestinarian framework. Travelers in Florida and the Atlantic world divided humanity into two stable categories that people were born into: elect “visible saints,” the reformed Christians, and damned, visible idolaters, cannibals, sodomites, and other heretics, including Catholics. Though they hoped to meet elect members among Indigenous people, they met with resistance to Christianity that they interpreted as a lack of grace.

Throughout the paper K denotes a fixed algebraically closed field. All algebras considered are finite-dimensional associative K-algebras with a unit element. Moreover, they are assumed to be basic and connected. For an algebra A we denote by mod(A) the category of all finitely generated right A-modules, and mod(A) denotes the stable category of mod(A), i.e. mod(A)/℘ where ℘ is the two-sided ideal in mod(A) of all morphisms that factorize through projective A-modules. Two algebras A and B are said to be stably equivalent if the stable categories mod(A) and mod(B) are equivalent. The study of stable equivalences of algebras has its sources in modular representation theory of finite groups. It is of importance in this theory whether two stably equivalent algebras have the same number of pairwise non-isomorphic nonprojective simple modules. Another motivation for studying stable equivalences appears in the following context. If E is a K-algebra of finite global dimension then its derived category Db(E) is equivalent to the stable category mod(Ê) of the repetitive category Ê of E [15]. Thus the problem of a classification of derived equivalent algebras leads in many cases to a classification of stably equivalent selfinjective algebras.

AbstractWe investigate cluster-tilting objects (and subcategories) in triangulated 2-Calabi–Yau and related categories. In particular, we construct a new class of such categories related to preprojective algebras of non-Dynkin quivers associated with elements in the Coxeter group. This class of 2-Calabi–Yau categories contains, as special cases, the cluster categories and the stable categories of preprojective algebras of Dynkin graphs. For these 2-Calabi–Yau categories, we construct cluster-tilting objects associated with each reduced expression. The associated quiver is described in terms of the reduced expression. Motivated by the theory of cluster algebras, we formulate the notions of (weak) cluster structure and substructure, and give several illustrations of these concepts. We discuss connections with cluster algebras and subcluster algebras related to unipotent groups, in both the Dynkin and non-Dynkin cases.


Continuous air turbulence measurements were made near the centre of the town of Reading for a period of one year. These were intended to provide data for deriving diffusion parameters for calculating the dispersion of pollution from chimneys in the town. They were obtained by using a bivane mounted on a 14 m mast, and the intensities of lateral and vertical turbulence for 1 h periods were derived by means of electronic analysers. Similar measurements were made for a period of about 4 weeks on the roof of a building at the B.P. Research Centre, Sunbury-on-Thames. The values of intensity of turbulence were grouped according to Turner’s stability categories and the averages within the groups were compared by variance analysis. This showed significant differences in turbulence between the unstable categories and the neutral category, but the stable categories were not distinguished from neutral. The addition of a filter to cut out the high frequency band of the fluctuations showed that a considerable portion of the measured turbulence had been in this band and this is attributed to mechanical turbulence produced by the surrounding buildings. Eliminating the high frequency band also distinguishes the stable categories from neutral. The measurements of intensity of turbulence have been used to estimate the spread of plumes in the town. The lateral spread is greater than that published by other authors but the vertical spread is similar.

This introductory chapter provides an overview of the book’s main themes. This book examines the population categories constructed and utilized every ten years by the US census. Approaching these categories from a historical perspective rather than a strictly sociological or political one permits their analysis as sites of internal and external mobilization. It also reveals the hidden evolutions by which the contents of seemingly stable categories changed while the definitions remain the same. Long-standing categories of race, such as white or black, have varied dramatically across periods and regions. Based on distinctions of origin and status—between free and slave, white and non-white, native-born Americans and immigrants or children of immigrants—over a period of a century and a half, from the creation of the federal census in 1790 to the 1940s, this study retraces the genealogy and evolution of these categories.
