'Worldly' pedagogy: a way of conceptualizing teaching towards global citizenship

In this paper, we discuss the characteristics of a form of pedagogy capable of addressing difference across nations and cultures in ways that do not inflate difference. We suggest that those conceptual insights are particularly relevant to the teaching of ‘global citizenship’. We have labelled this a ‘worldly’ pedagogy, because of the connection to teaching in a global context, and with reference to Arendt’s concept of ‘worldliness’ and the ‘worldly’ experience of human beings in their plurality sharing a ‘common world’ (Arendt 1958). Our conceptual framework results from our analysis of a specific educational environment which we investigated through a small grant obtained from the Higher Education Academy (UK) that examined the pedagogies used to promote learning amongst two polarised (Palestinian and Israeli) communities. We carried out eight interviews with participants to this programme, and report on the outcomes of this study. This paper contributes to the debate on tribal identities (Beck 2006; Hill 2000; Appiah 2006 for example) through the challenge it offers to positions on difference that display rigid essentialising identity readings and to homogenizing discourses that fail to appreciate the differences within cultures/nations/groups

Nonverbal communication in health settings

The goal of the present chapter is to provide an overview of the existing literature on nonverbal communication in the medical encounter. After introducing the different functions of nonverbal behavior and its importance in the medical context, we present empirical evidence showing how physician nonverbal behavior relates to different patient outcomes such as satisfaction, trust, or adherence. We then present different models and assessment tools with which nonverbal behavior in the medical encounter can be studied. The physician's ability to pick up and correctly interpret the patient's nonverbal cues (interpersonal sensitivity) and its impact on patient outcomes will be reviewed. We close the chapter by providing a summary of the main results and an outlook on open questions in the field

Beyond "one size fits all": Physician nonverbal adaptability to patients' need for paternalism and its positive consultation outcomes

In this study, we tested whether physicians' ability to adapt their nonverbal behavior to their patients' preferences for a paternalistic interaction style is related to positive consultation outcomes. We hypothesized that the more physicians adapt their nonverbal dominance behavior to match their patients' preferences for physician paternalism, the more positive the patients perceive the medical interaction. We assessed the actual nonverbal dominance behavior of 32 general practitioners when interacting with two of their patients and compared it with each of their patients' preferences for paternalism to obtain a measure of adaptability. Additionally, we measured patient outcomes with a questionnaire assessing patient satisfaction, trust in the physician, and evaluation of physician competence. Results show that the more nonverbal dominance the physician shows towards the patient who prefers a more paternalistic physician, as compared to towards the patient who prefers a less paternalistic physician (i.e., the more the physician shows nonverbal behavioral adaptability), the more positive the consultation outcomes are. This means that physicians' ability to adapt aspects of their nonverbal dominance behavior to their individual patients' preferences is related to better outcomes for patients. As this study shows, it is advantageous for patients when a physician behaves flexibly instead of showing the same behavior towards all patients. Physician training might want to focus more on teaching a diversity of different behavior repertoires instead of a given set of behaviors

Attosecond Streaking in the Water Window: A New Regime of Attosecond Pulse Characterization

We report on the first streaking measurement of water-window attosecond pulses generated via high harmonic generation, driven by sub-2-cycle, CEP-stable, 1850 nm laser pulses. Both the central photon energy and the energy bandwidth far exceed what has been demonstrated thus far, warranting the investigation of the attosecond streaking technique for the soft X-ray regime and the limits of the FROGCRAB retrieval algorithm under such conditions. We also discuss the problem of attochirp compensation and issues regarding much lower photo-ionization cross sections compared with the XUV in addition to the fact that several shells of target gases are accessed simultaneously. Based on our investigation, we caution that the vastly different conditions in the soft X-ray regime warrant a diligent examination of the fidelity of the measurement and the retrieval procedure.Comment: 14 Pages, 12 figure

A Forward Genetic Approach in Chlamydomonas reinhardtii as a Strategy for Exploring Starch Catabolism

International audienceA screen was recently developed to study the mobilization of starch in the unicellular green alga Chlamydomonas reinhardtii. This screen relies on starch synthesis accumulation during nitrogen starvation followed by the supply of nitrogen and the switch to darkness. Hence multiple regulatory networks including those of nutrient starvation, cell cycle control and light to dark transitions are likely to impact the recovery of mutant candidates. In this paper we monitor the specificity of this mutant screen by characterizing the nature of the genes disrupted in the selected mutants. We show that one third of the mutants consisted of strains mutated in genes previously reported to be of paramount importance in starch catabolism such as those encoding β-amylases, the maltose export protein, and branching enzyme I. The other mutants were defective for previously uncharacterized functions some of which are likely to define novel proteins affecting starch mobilization in green algae

The Hunt for the “Holy Grail”: Condensed Tannins in Perennial Forage Legumes

A recent advance using molecular biology has identified a transcription factor or master switch that can ‘turn on’ the condensed tannin pathway present in white clover, and with the appropriate promoters allows biologically significant levels of condensed tannin expression in leaf tissue. In vitro tests have demonstrated that the condensed tannins produced in white clover leaves can bind protein at a pH 6.5, as found in the rumen, and then release them at pH 2.5, the pH in the abomasum, before entering the small intestine for amino acid absorption. Additional tests have demonstrated that these condensed tannins can reduce methane production by up to 25% in the first 6 hours of incubation. The journey to this point and the challenges ahead to deliver white clover cultivars with condensed tannin expression will be described

Activity-Dependent Bulk Endocytosis and Clathrin-Dependent Endocytosis Replenish Specific Synaptic Vesicle Pools in Central Nerve Terminals

Multiple synaptic vesicle (SV) retrieval modes exist in central nerve terminals to maintain a continual supply of SVs for neurotransmission. Two such modes are clathrin-mediated endocytosis (CME), which is dominant during mild neuronal activity and activity-dependent bulk endocytosis (ADBE), which is dominant during intense neuronal activity. However little is known about how activation of these SV retrieval modes impact on the replenishment of the total SV recycling pool and the pools that reside within it; the readily releasable pool (RRP) and reserve pool. To address this question, we examined the replenishment of all three SV pools by triggering these SV retrieval modes during both high and low intensity stimulation of primary rat neuronal cultures. SVs generated by CME and ADBE were differentially labelled using the dyes FM1-43 and FM2-10 and their replenishment of specific SV pools was quantified using stimulation protocols that selectively depleted each pool. Our studies indicate that while the RRP was replenished by CME-generated SVs, ADBE provided additional SVs to increase the capacity of the reserve pool. Morphological analysis of the uptake of the fluid phase marker horse radish peroxidase corroborated these findings. The differential replenishment of specific SV pools by independent SV retrieval modes illustrates how previously experienced neuronal activity impacts on the capability of central nerve terminals to respond to future stimuli

Apatites in Gale Crater

ChemCam is an active remote sensing instrument suite that has operated successfully on MSL since landing Aug. 6th, 2012. It uses laser pulses to remove dust and to analyze rocks up to 7 m away. Laser-induced breakdown spectroscopy (LIBS) obtains emission spectra of materials ablated from the samples in electronically excited states. The intensities of the emission lines scale with the abundances of the related element. ChemCam is sensitive to most major rock-forming elements as well as to a set of minor and trace elements such as F, Cl, Li, P, Sr, Ba, and Rb. The measured chemical composition can then be used to infer the mineralogical composition of the ablated material. Here, we report a summary of inferred apatite detections along the MSL traverse at Gale Crater. We present the geologic settings of these findings and derive some interpretations about the formation conditions of apatite in time and space
