Over the last 50 years, the production and consumption of chicken meat have soared in Bolivia. This paper analyzes the political, economic, and cultural developments that have led to the popularity of chicken meat in this country. It also asks who has benefitted from this success story. The author uses data from one year of multi-sited ethnographic fieldwork in Bolivia in order to give an account

The displacement speed that characterises the self-propagation of isosurfaces of a reaction progress variable is of key importance for turbulent premixed reacting flow. The evolution equation for the displacement speed was derived in a recent work of Yu and Lipatnikov (Phys Rev E 100:013107, 2019a) for the case where the flame is described by a transport equation for single reaction progress varia

The Damages Directive has been celebrated as a milestone for the private enforcement of EU competition law. The Directive harmonises national procedural laws and aims to facilitate full compensation for damages occurred as a result of competition law violations. At the same time, US and EU businesses more frequently use contractual clauses that might present obstacles in obtaining compensation. Re

Aim: Kynurenine metabolites are potential modulators of psychiatric disease. We aimed to develop a highly sensitive biochemical analysis of cerebrospinal fluid (CSF) tryptophan (TRP) metabolites, to investigate the stability of metabolites and to confirm our previous findings of aberrant CSF quinolinic acid (QUIN) and picolinic acid (PIC) in suicide attempters using this method. Methodology &

In this study, Spatial Multi-Criteria Evaluation and the least cost path analysis were applied to find the optimal by-pass road alignment in the Tlokweng Planning Area in Botswana. One-At-a-Time sensitivity analysis and the statistical test for zero proportion were used to investigate the robustness of the entire model. Four alternative by-pass roads were produced stressing economic, environmental

In order to overcome the shortcomings of crash data a number of surrogate measures of safety have been developed and proposed by various researchers. One of the most widely used temporal indicators is time-to-collision (TTC) which requires the road users to be on a collision course. Road users that are strictly speaking not on a collision course actually might behave and take evasive actions as if

In this paper we provide a counterpoint to conventional views on integrative reviews in knowledge development, as exemplified by Elsbach and Van Knippenberg (2020). First, we critique their proposed integrative review by identifying and problematizing several key assumptions underlying it, particularly their idea that the integrative review can simply build on existing studies and lead the way to

Objective: To develop and externally validate prediction models for incident hand osteoarthritis (OA) in a large population-based cohort of middle aged and older men and women. Design: We included 17,153 men and 18,682 women from a population-based cohort, aged 35–70 years at baseline (1995–1997). Incident hand OA were obtained from diagnostic codes in the Norwegian National Patient Register (1995

Humor is essential to social life, but it is often overlooked in the study of crime and other social problems. We introduce and make use of humor theory, emphasizing the theories of superiority and relief. Based on interviews with incarcerated men, we demonstrate how humor is used to criticize authorities, for self-aggrandizement, and to alleviate the pain of tragic experiences. Funny remarks and

The growth of a planetary core by pebble accretion stops at the so-called pebble isolation mass, when the core generates a pressure bump that traps drifting pebbles outside its orbit. The value of the pebble isolation mass is crucial in determining the final planet mass. If the isolation mass is very low, gas accretion is protracted and the

Botulinum neurotoxins (BoNTs), the most potent toxins known, are potential bioterrorism agents. It is well established that all seven serotypes of BoNTs (BoNT/A-G) require complex gangliosides as co-receptors. Here, we report that BoNT/DC, a presumed mosaic toxin between BoNT/D and BoNT/C1, binds and enters efficiently into neurons lacking complex gangliosides and shows no reduction in toxicity in

The Absolut Company har öppnat besökscentret Absolut Home i Åhus och detta har potential att medföra ett stort antal värden för orten. Forskarna har studerat bådeturistaktörers och Åhusbors syn på värden för att ta reda på hur de ställer sig till det nya besökscentret i sin ort.

The differences between two standard Monte Carlo models, LEPTO and ARIADNE, for deep inelastic scattering at small-χ is analysed in detail. It is shown that the difference arises from a 'unorthodox' suppression factor used in ARIADNE which replaces the normal ratio of parton densities. This gives rise to a factor that qualitatively is similar to what one would expect from BFKL dynamics for some ob

PIXE is nowadays a routine analytical technique in the study of atmospheric aerosols. If it aspires to continue to be so in the future, it will have to compete with a range of other powerful analytical techniques, and outperform them in some respect. It will be shown how PIXE can indeed play an important role in future studies of atmospheric aerosols. For clarification, two concrete examples will

The production of continuously distributed X-rays by the impact of protons of 1.9-3.0 MeV for X-ray energies between 4 and 6.5 keV, and 1.9-2.65 MeV for X-ray energies between 1.7 and 4 keV has been investigated. Five different target types have been irradiated: polyethylene, polystyrene, carbon. KaptonTM and MylarTM. The results are presented as absolute cross sections for continuous X-ray produc

The fourth version of the Ariadne program for generating QCD cascades in the colour dipole approximation is presented. The underlying physics issues are discussed and a manual for using the program is given together with a few sample programs.The major changes from previous versions are the introduction of photon radiation from quarks and inclusion of interfaces to the LEPTO and PYTHIA programs.
