Humans and fire: changing relations in early agricultural and built environments in the Zagros, Iran, Iraq

Fire-centred studies have recently been highlighted as powerful avenues for investigation of energy flows and relations between humans, materials, environments and other species. The aim in this paper is to evaluate this potential first by reviewing the diverse theories and methods that can be applied to investigate the ecological and social significance of anthropogenic fire, and second by applying these to new and existing data sets in archaeology. This paper examines how fire-centred approaches can inform on one of the most significant step-changes in human lifeways and inter-relations with environment and other species – the transition from mobile hunting-gathering to more sedentary agriculture in a key heartland of change, the Zagros region of Iraq and Iran, c. 12,000–8,000 BP. In the review and case studies multiple links are investigated between human fire use and environment, ecology, energy use, technology, the built environment, health, social roles and relations, cultural practices and catastrophic events

Flight to quality? An investigation of changing price spreads in commercial real estate markets

Purpose – The purpose of this paper is to investigate the effect of the crisis on the pricing of asset quality attributes. This paper uses sales transaction data to examine whether flight from risk phenomena took place in the US office market during the financial crisis of 2007-2009. Design/methodology/approach – Hedonic regression procedures are used to test the hypothesis that the spread between the pricing of low-quality and high-quality characteristics increased during the crisis period compared to the pre-crisis period. Findings – The results of the hedonic regression models suggest that the price spread between Class A and other properties grew significantly during the downturn. Research limitations/implications – Our results are consistent with the hypothesis of an increased price spread following a market downturn between Class A and non-Class A offices. The evidence suggests that the relationships between the returns on Class A and non-Class A assets changed during the period of market stress or crisis. Practical implications – These findings have implications for real estate portfolio construction. If regime switches can be predicted and/or responded to rapidly, portfolios may be rebalanced. In crisis periods, portfolios might be reweighted towards Class A properties and in positive market periods, the reweighting would be towards non-Class A assets. Social implications – The global financial crisis has demonstrated that real estate markets play a crucial role in modern economies and that negative developments in these markets have the potential to spillover and create contagion for the larger economy, thereby affecting jobs, incomes and ultimately people’s livelihoods. Originality/value – This is one of the first studies that address the flight to quality phenomenon in commercial real estate markets during periods of financial crisis and market turmoil.

The changing influence of societal culture on job satisfaction across Europe

This paper contributes to the growing multidisciplinary body of literature on subjective well-being by investigating the longitudinal stability and impact of societal cultural values (SCVs) – as opposed to the more common organizational values – on job satisfaction. It is assumed that SCVs evolve slowly; hence, their impact on job satisfaction is likely to remain stable over time. False adherence to this assumption could cause misalignment between organizational policies/practices and expectations formed by societal culture, decreasing job satisfaction and adversely affecting productivity, competiveness and prosperity. Four waves of the European Values Study are used to examine whether SCVs have evolved and their impacts on job satisfaction over a relatively short time: 1981–2008. SCVs are parameterized through reference to traditional vs secular-rational, and survival vs self-expression value continuums. Results indicate that the strength of many SCVs has declined, the impacts of traditional societal values on job satisfaction have remained fairly constant, and the impacts of survival societal values on job satisfaction have declined substantially over this sample period. These reductions in SCVs amplify the importance of accounting for such changes when designing new or adjusting existing policies/practices to enhance job satisfaction and stimulate improvements in productivity, competitiveness and prosperity.

Changing attitudes, beliefs and feelings towards food in bulimic patients

Eating attitudes are defined as beliefs. thoughts, feelings and behaviors towards food. Bulimia nervosa (BN) is ail eating disorder, in which the eating, attitudes are Seriously disturbed. Studies that evaluated nutritional aspects of BN focus mainly oil food intake, dietary restriction and binge eating. while the follow-up Studies evaluate mainly clinical symptoms. The objective of this study was to evaluate eating attitudes of patients with BN. during and after cognitive-behavioral intervention. Thirty nine (39) BN female patients received cognitive behavioral treatment with a Multidisciplinary team and had eating attitudes assessed by a questionnaire developed for this research. Frequencies of the attitudes assessed were compared at baseline. after 12 weeks and 24 weeks of treatment. After treatment, patients had less distorted beliefs about food, less guilty after eating ""forbidden"" foods and they felt more tranquil while caring outside home. Other negative behaviors, as dietary restriction, the desire of not cat, being angry when feeling hungry and using the food to relive stress. persisted. Eating attitudes of patients with BN are hard to be changed in a short-term. More attention to this disease`s component and new approaches to treatment are needed in order to have a better recovery.

Transport control in fusion plasmas by changing electric and magnetic field spatial profiles

For magnetically confined plasmas in tokamaks, we have numerically investigated how Lagrangian chaos at the plasma edge affects the plasma confinement. Initially, we have considered the chaotic motion of particles in an equilibrium electric field with a monotonic radial profile perturbed by drift waves. We have showed that an effective transport barrier may be created at the plasma edge by modifying the electric field radial profile. In the second place, we have obtained escape patterns and magnetic footprints of chaotic magnetic field lines in the region near a tokamak wall with resonant modes due to the action of an ergodic magnetic limiter. For monotonic plasma current density profiles we have obtained distributions of field line connections to the wall and line escape channels with the same spatial pattern as the magnetic footprints on the tokamak walls.

Mixture of changing uniaxial micellar forms in lyotropic biaxial nematics

Lyotropic nematics consisting of surfactant-cosurfactant water solutions may present a biaxial phase or direct U(+) <-> U(-) transitions, in different regions of the temperature-relative concentration phase diagram, for different systems and compositions. We propose that these may be related to changes of uniaxial micellar form, which may occur either smoothly or abruptly. Smooth change of cylinder-like into disc-like shapes requires a distribution of Maier-Saupe interaction constants and we consider two limiting cases for the distribution of forms: a single Gaussian and a double Gaussian. Alternatively, an abrupt change of form is described by a discontinuous distribution of interaction constants. Our results show that the dispersive distributions yield a biaxial phase, while an abrupt change of shape leads to coexistence of uniaxial phases. Fitting the theory to the experiment for the ternary system KL/decanol/D2O leads to transition lines in very good agreement with experimental results. In order to rationalise the results of the comparison, we analyse temperature and concentration form dependence, which connects micellar and experimental macroscopic parameters. Physically consistent variations of micellar asymmetry, amphiphile partitioning and volume are obtained. To the best of the authors` knowledge, this is the first truly statistical microscopic approach that is able to model experimentally observed lyotropic biaxial nematic phases.

A new proposal for the picture changing operators in the minimal pure spinor formalism

Using a new proposal for the ""picture lowering"" operators, we compute the tree level scattering amplitude in the minimal pure spinor formalism by performing the integration over the pure spinor space as a multidimensional Cauchy-type integral. The amplitude will be written in terms of the projective pure spinor variables, which turns out to be useful to relate rigorously the minimal and non-minimal versions of the pure spinor formalism. The natural language for relating these formalisms is the. Cech-Dolbeault isomorphism. Moreover, the Dolbeault cocycle corresponding to the tree-level scattering amplitude must be evaluated in SO(10)/SU(5) instead of the whole pure spinor space, which means that the origin is removed from this space. Also, the. Cech-Dolbeault language plays a key role for proving the invariance of the scattering amplitude under BRST, Lorentz and supersymmetry transformations, as well as the decoupling of unphysical states. We also relate the Green`s function for the massless scalar field in ten dimensions to the tree-level scattering amplitude and comment about the scattering amplitude at higher orders. In contrast with the traditional picture lowering operators, with our new proposal the tree level scattering amplitude is independent of the constant spinors introduced to define them and the BRST exact terms decouple without integrating over these constant spinors.

Läraryrket - kall eller profession? : Enkätundersökning med nyantagna lärarstudenter om deras motiv till yrkesvalet

Syftet med denna uppsats har varit att undersöka vilka faktorer som påverkar lärarstudenters val till lärarprogrammet samt att undersöka om det fortfarande finns någon sorts kall till yrket. En anledning till detta syfte är att läraryrkets status har sjunkit och att media oftast ensidigt rapporterar om de problem och missförhållanden som råder i skolor och på lärarutbildningar. Undersökningsmaterialet utgörs av en enkätundersökning som genomförts bland lärarstudenter som gått en termin på lärarprogrammet vid en högskola i Mellansverige. Sammanlagt har 111 personer besvarat enkäten. Resultatet visar att det fortfarande finns kall-tankar i lärarstudenternas motiv. De flesta angav motiv som var inriktade mot att arbeta med och fostra barn, dvs. klientfokuserade. Kvinnorna angav i högre grad än männen de motiv som hörde till kallet. Ett annat vanligt motiv var att utbildningen var personligt utvecklande. Tidigare lärare som studenterna hade haft påverkade deras val till stor del. Lärarstudenterna trodde att de som färdiga lärare ibland kommer att hoppa över egna raster och gå till arbetet trots att de känner sig sjuka om det gynnar eleverna. Männen var mer villiga till detta än kvinnorna. Även ur detta beteende kan kall-tankar utläsas.

Socialt arbeteEn diskursanalys av ett begreppmellan kall och profession

Vårt syfte är att se hur begreppet socialt arbete konstrueras genom tal och text, av studenterna på socialarbetarprogrammet Högskolan Dalarna. Detta har vi gjort genom att titta på hur diskursen socialt arbete ser ut hos studenterna på termin ett respektive termin fem. Vi kommer att titta på frågeställningarna ur ett socialkonstruktionistiskt perspektiv för att se hur studenterna med hjälp av språket konstruerar innebörden av begreppet socialt arbete. Vi gjorde sex stycken semistrukturerade intervjuer som vi sedan har analyserat genom ett diskursanalytiskt perspektiv. Vi har använt oss av Norman Fairclough kritiska diskursanalys men har anpassat hans modell till vår undersöknings syfte och frågeställning. Vårt intresse för denna undersökning bottnar i definitionsproblematiken kring socialt arbete. Vi har funnit, i likhet med tidigare forskning att det är svårt att säga vad socialt arbete är och att det är problematiskt att avgränsa området. Det vi kan utläsa är att skillnaden mellan studenterna på de olika terminerna i talet kring socialt arbete inte var lika stor som vi förväntade oss utan att man snarare kan identifiera vissa likheter mellan deras språkliga diskurser av vad socialt arbete är och vilka som utför detta.

A new life in the mountains : changing lifestyles among in-migrants to Wanaka, New Zealand

Mountainous areas with a high dependency on its tourism industry are often relatively small and remote. But some of these areas have faced a population increase due to large in-migration;Wanaka in New Zealand’s Southern Alps is one example. This paper is studying the migration motivations of a few individuals that have moved to Wanaka and how they started to feel like part of their new community. The meaning of the place is important for these newcomers. The results of the study indicate that there is a strong link between the community and the lifestyle that in-migrants are seeking. It also highlights the importance for in-migrants to be a part of the social community. Social Clubs, sport clubs and voluntary work are ways of becoming a part of a social network.
