    This is a postprint of an article whose final and definitive form has been published in Research Papers in Education© 2002 Copyright Taylor & Francis; Research Papers in Education is available online at http://www.informaworld.comThis paper examines and summarizes research into performance-related pay. It was undertaken as part of the Teachers' Incentive Pay Project, currently in progress at the University of Exeter, which is a study of the introduction of threshold assessment and performance management for teachers in schools in England and Wales. The paper examines research into the effects of pay on employees' behaviour and considers the claimed benefits and disadvantages of performance-related pay, both generally and with particular reference to the teaching profession. Proponents of performance-related pay claim that it improves the motivation of employees and assists in the recruitment and retention of high quality staff. Disadvantages include: neglect of unrewarded tasks; disagreement about goals; competitiveness; lack of openness about failings; cost and the possibility of demotivating those who are not rewarded. Performance-related pay has long been a feature of teachers' remuneration in the US, where it has usually been promoted in response to national crises perceived to be rooted in educational failure. Traditionally, most US merit pay schemes for teachers have not been long lasting. This paper considers research into a variety of US schemes, including studies of the conditions under which they are found to succeed. Performance-related pay works best in situations in which there are easily measured outcomes, such as in manufacturing, but the outcomes of teaching are many and varied and there have been problems related to measuring teachers' effectiveness. The paper reports claims by Odden (2000) that measuring teachers' performance is now more feasible and that, therefore, the time is right for the introduction of performance-related pay for teachers

    Defining high endothelial venules and tertiary lymphoid structures in cancer

    High endothelial venules (HEVs) are structurally distinct blood vessels that develop during embryonic and neonatal life in all secondary lymphoid organs except the spleen. HEVs are critical for initiating and maintaining immune responses because they extract naïve and memory lymphocytes from the bloodstream, regardless of antigen receptor specificity, and deliver them to antigen-presenting cells inside lymph nodes under homeostatic conditions. HEVs also develop postnatally in nonlymphoid organs during chronic inflammation driven by autoimmunity, infection, allografts, and cancer. Extranodal HEVs are usually surrounded by dense lymphocytic infiltrates organized into lymph-node like, T- and B-cell-rich areas called tertiary lymphoid structures (TLS). HEV neogenesis is thought to facilitate the generation of tissue-destroying lymphocytes inside chronically inflamed tissues and cancers. We are studying the mechanisms underpinning HEV neogenesis in solid cancers and the role of homeostatic T-cell trafficking in controlling cancer immunity. In this chapter we describe methods for identifying HEV in tissue sections of cancerous tissues in humans and mice using immunohistochemical staining for the HEV-specific marker peripheral lymph node addressin (PNAd). L-selectin binding to PNAd is a necessary first step in homeostatic lymphocyte trafficking which is the defining function of HEV. We also describe methods to measure L-selectin-dependent homing of lymphocytes from the bloodstream into lymphoid tissues and tumors in preclinical cancer model

    The origins and spread of domestic horses from the Western Eurasian steppes

    Analysis of 273 ancient horse genomes reveals that modern domestic horses originated in the Western Eurasian steppes, especially the lower Volga-Don region.Domestication of horses fundamentally transformed long-range mobility and warfare(1). However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling(2-4) at Botai, Central Asia around 3500 bc(3). Other longstanding candidate regions for horse domestication, such as Iberia(5) and Anatolia(6), have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 bc, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association(7) between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 bc(8,9) driving the spread of Indo-European languages(10). This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium bc Sintashta culture(11,12).Descriptive and Comparative Linguistic
