QCD Predictions for the Transverse Energy Flow in Deep-Inelastic Scattering in the Small x HERA Regime
The distribution of transverse energy, , which accompanies
deep-inelastic electron-proton scattering at small , is predicted in the
central region away from the current jet and proton remnants. We use BFKL
dynamics, which arises from the summation of multiple gluon emissions at small
, to derive an analytic expression for the flow. One interesting
feature is an increase of the distribution with
decreasing , where . We perform a
numerical study to examine the possibility of using characteristics of the
distribution as a means of identifying BFKL dynamics at HERA.Comment: 16 pages, REVTEX 3.0, no figures. (Hardcopies of figures available on

Understanding practitioner professionalism in Aboriginal and Torres Strait Islander health: lessons from student and registrar placements at an urban Aboriginal and Torres Strait Islander primary health care service
Aboriginal and Torres Strait Islander peoples continue to be pathologised in medical curriculum, leaving graduates feeling unequipped to effectively work cross-culturally. These factors create barriers to culturally safe health care for Aboriginal and Torres Strait Islander peoples.
In this pilot pre-post study, we followed the learning experiences of 7 medical students and 4 medical registrars undertaking clinical placements at an urban Aboriginal and Torres Strait Islander primary health care service in 2014. Through analysis and comparison of pre- and post-placement responses to a paper-based case study of a fictitious Aboriginal patient, we identified four learning principles for medical professionalism: student exposure to nuanced, complex and positive representations of Aboriginal peoples; positive practitioner role modelling; interpersonal skills that build trust and minimise patient-practitioner relational power imbalances; and, knowledge, understanding and skills for providing patient centred, holistic care. Though not exhaustive, these principles can increase the capacity of practitioners to foster culturally safe and optimal health care for Aboriginal peoples. Furthermore, competence and effectiveness in Aboriginal health contexts is an essential component of medical professionalism
The Potential of Grassland and Associated Forages to Produce Fibre, Biomass, Energy or Other Feedstocks for Non-Food and Other Sectors: New Uses for a Global Resource
In developed countries increased areas of land will become available for non-food production. Recent reforms of the Common Agricultural Policy will further intensify this trend in Europe. There is potential for grassland and associated species to contribute to large tonnage markets of energy and bulk fibres, to the supply of fermentation products and to speciality markets, but processes and approaches to the market are not as yet developed. There is potential for the establishment of Graminaceous species - specifically for non- food use. For European conditions particular attention is being given to Miscanthus sinensis (Miscanthus), Arundo donax (Giant Reed), Phalaris arundinacea (Reed Canary Grass) and Spartina spp. (Cord grass, Marsh Grass). Whilst grass and forage species could be used for individual non-food uses (e.g. biomass for energy), value may be added by adopting a biorefinery approach in which a range of products are derived from the different components in the feedstock
Les villages tanzaniens ujamaa 40 ans plus tard : Moralisation et commémoration du collectivisme
Entre 1967 et 1977, quelque 10 millions de Tanzaniens ont Ă©tĂ© dĂ©placĂ©s de leur terre affermĂ©e et regroupĂ©s dans des villages ujamaa (littĂ©ralement, familyhood) bĂątis par suite dâune dĂ©cision gouvernementale, donnant lieu ainsi Ă lâun des plus vastes programmes de rĂ©installation de lâhistoire. Le prĂ©sident Julius Nyerere, « pĂšre » et philosophe du socialisme tanzanien, a justifiĂ© la villagisation en allĂ©guant quâelle permettrait dâamĂ©liorer la prestation de services de base Ă la population, tels que des cliniques mĂ©dicales, des Ă©coles et de lâeau potable. Or, dans la foulĂ©e de lâabandon progressif du programme et du discours socialistes au milieu des annĂ©es 1980, le sort de ces villages demeure dans une large mesure inconnu. Comment les villageois Ă©valuent-ils de nos jours la vie dans ces villages comparativement Ă ce quâelle Ă©tait Ă lâĂ©poque socialiste? Quels Ă©lĂ©ments de la coopĂ©ration communale, sâil sâavĂšre que celleâci a vĂ©ritablement existĂ©, ont Ă©tĂ© maintenus? Cet article fait Ă©tat dâune enquĂȘte rĂ©alisĂ©e auprĂšs de rĂ©sidants dâanciens villages ujamaa de la rĂ©gion de Mwanza. Leurs tĂ©moignages apportent certaines rĂ©ponses Ă ces questions et sont mis en contexte dans une plus vaste analyse de la politique agricole tanzanienne sous les rĂ©gimes socialiste et postsocialiste.Between 1967 and 1977, some 10 million Tanzanians were moved from scattered individual holdings into government mandated Ujamaa (literally, âfamilyhoodâ) villages in one of the largest resettlement movements in history. President Julius Nyerere, âfatherâ and philosopher of Tanzanian socialism, justified villagization on the grounds of being better able to provide basic services, such as medical clinics, schools, and clean water, to the citizenry. Yet in the wake of the quiet abandonment of socialist policy and rhetoric in the mid-1980s, the fate of these villages remains largely unknown. How do villagers evaluate life in these villages now as compared to socialist times? Have any elements of communal cooperation that may have existed been retained? In this paper, interviewed with residents in former Ujamaa villages in Mwanza Region provide some answers to these questions and are contextualized within a broader analysis of agricultural policy in socialist and postsocialist Tanzania.Entre 1967 y 1977, cerca de 10 millones de tanzano fueron desplazados de las tierras que rentaban y reagrupados en pueblos ujamaa (literalmente, lotes familiares) construidos por designio gubernamental, justificando asĂ uno de los mĂĄs vastos programas de re-localizaciĂłn de la historia. El presidente Julios Nyerere «padre» y filĂłsofo del socialismo tanzano, habĂa justificado la creaciĂłn de esos pueblos argumentando que eso permitirĂa mejorar la prestaciĂłn de servicios de base a la poblaciĂłn, tal y como las clĂnicas mĂ©dicas, las escuelas y el agua potable. Ahora bien, con el abandono progresivo del programa y del discurso socialista a mediados de los años 1980, aun se ignora cual serĂĄ el destino de dichos pueblos. ÂżCĂłmo sus habitantes evalĂșan actualmente la vida en esos pueblos comparada con lo que vivĂan durante la Ă©poca socialista? ÂżCuĂĄles son los elementos de la cooperaciĂłn comunal, si realmente existiĂł, que han perdurado? Este artĂculo reporta una investigaciĂłn realizada entre los residentes de los antiguos pueblos ujamaa de la regiĂłn de Mwanza. Sus afirmaciones permiten dilucidar ciertas cuestiones y han sido contextualizadas en el cuadro de un anĂĄlisis mĂĄs vasto de la polĂtica agrĂcola tanzana bajo los regĂmenes socialistas y post-socialistas

BFKL versus HERA
The BFKL equation and the kT-factorization theorem are used to obtain
predictions for F2 in the small Bjorken-x region over a wide range of Q**2. The
dependence on the parameters, especially on those concerning the infrared
region, is discussed. After a background fit to recent experimental data
obtained at HERA and at Fermilab (E665 experiment), we find that the predicted,
almost Q**2 independent BFKL slope lambda >= 0.5 appears to be too steep at
lower Q**2 values. Thus there seems to be a chance that future HERA data can
distinguish between pure BFKL and conventional field theoretic renormalization
group approaches.Comment: 26 pages, 6 eps figures, LaTeX2e using epsfig.sty and amssymb.st

Current Trends Of Unethical Behavior Within Organizations
A substantial body of research reveals that unethical behavior continues to be a concern in the workplace. This article presents information on the prevalence of unethical behavior, antecedents of unethical behavior, the organizational environment, cognitive moral development, and trends of unethical behavior over a 3 year span. Findings of earlier studies generally agree that unethical behavior has a negative effect in the workplace. The greatest research effort on this issue has been to continue to conduct studies within organizations, identifying if the issue of unethical behavior is improving or stagnant
The description of F2 at small x incorporating angular ordering
We study the perturbative QCD description of the HERA measurements of using a gluon distribution that is obtained from an evolution
incorporating angular ordering of the gluon emissions, and which embodies both
GLAP and BFKL dynamics. We compare the predictions with recent HERA data for
. We present estimates of the charm component and of .Comment: 8 LaTeX pages + 4 uuencoded figure
