Identifying the chaîne opératoire of club-rush (Bolboschoenus glaucus (Lam.) S.G.Sm) tuber exploitation during the Early Natufian in the Black Desert (northeastern Jordan)

Club-rush (Bolboschoenus spp. (Asch.) Palla) is one of the most common edible wild plant taxa found at Epipaleolithic and Neolithic sites in southwest Asia. At the Early Natufian site of Shubayqa 1 (Black Desert, Jordan) thousands of club-rush rhizome-tuber remains and hundreds of fragments of prepared meals were found. The evidence indicated that the underground storage organs of this plant were recurrently used as a source of food 14,600 years ago. To determine how Early Natufian communities gathered, processed and transformed club-rush tubers into food, we designed an interdisciplinary study that combined experimental archaeology, archaeobotany, and ground and chipped stone tool analyses. We conducted more than 50 specific experiments over three years, and based on the experimental materials produced we inferred that 1) the best season for club-rush rhizome-tuber collection in the region was spring-summer time; 2) that the primary method to harvest the plant would have been uprooting; and 3) that the most efficient approaches to obtain perfectly peeled and clean rhizome-tubers could have entailed drying, roasting and gentle grinding of the tubers. Overall, our work provides important information to reconstruct the chaîne opératoire for club-rush tuber exploitation in the past. The experimental data and modern reference datasets allow us to interpret the archaeological material found at Shubayqa 1, and start identifying some of the activities that Natufian communities in the Black Desert undertook in relation to the exploitation of this particular source of food.Funding to carry out the experiments described in this paper was provided by the H.P.

Understanding the power of the picture: The effect of image content on emotional and political responses to terrorism

Viewing images of terrorism can have a powerful impact on individuals’ emotional and political responses, yet little is known about the psychological processes underlying these effects. We hypothesized that the content of terrorism images will shape viewers’ appraisals of the event, which will elicit specific emotions and political attitudes. British citizens viewed photographs of the 2005 London bombings, either focusing on victims or terrorists. Exposure to images of victims increased appraisals of victim suffering, which predicted feelings of sympathy. Exposure to images of terrorists increased appraisals of terrorists as dangerous, which predicted fear; and of the attack as unjust, which predicted anger. Each emotion predicted support for a distinct counter-terrorism policy. Theoretical and practical implications are discussed

Appraisals, emotions and emotion regulation: An integrative approach

The present work aims to investigate the relation between appraisals, emotions, and emotion regulation strategies by creating a structural equation model which integrates these three aspects of the emotion process. To reach this aim, Italian students (N = 610) confronted with their high school diploma examination completed a questionnaire 3 weeks before the beginning of the exam. Results showed that they experienced primarily three types of emotions—anxiety/fear, frustration/powerlessness, positive emotions—which were related to specific appraisal profiles. Importantly, these appraisal profiles and emotions were associated with the use of different strategies for regulating emotions: anxiety/fear was associated with focusing on the exam, drug use, and an inability to distance oneself from the exam; frustration/powerlessness, with use of suppression, distancing, and drugs; positive emotion, with reappraisal and problem focused strategies. The effectiveness of these different strategies will be discussed

Orphan crops of archaeology-based crop history research

Agrobiodiversity is central to sustainable farming worldwide. Cultivation, conservation and reintroduction of diverse plant species, including ‘forgotten’ and ‘underutilized’ crops, contribute to global agrobiodiversity, living ecosystems and sustainable food production. Such efforts benefit from traditional and historical knowledge of crop plants' evolutionary and cultural trajectories. This review is a first attempt at systematically gauging species representativeness in studies of archaeological plant remains. Results indicate that, in addition to discipline-specific methodological sources of bias, modern agricultural biases may replicate themselves in crop history research and influence understandings of ‘forgotten crops’. Recognizing these biases is an initial stride towards rectifying them and promoting agrobiodiversity in both research and practical applications. Summary: So-called ‘forgotten’ or ‘orphan’ crops are an important component of strategies aimed at preserving and promoting biodiversity. Knowledge of historical cultivation, usage, and geographic and evolutionary trajectories of plants, that is, crop history research, is important for the long-term success of such efforts. However, research biases in the crops chosen for study may present hurdles. This review attempts to systematically identify patterns in crop species representativeness within archaeology-based crop history research. A meta-analysis and synthesis of archaeobotanical evidence (and lack thereof) is presented for 268 species known to have been cultivated for food prior to 1492 CE from the Mediterranean region to South Asia. We identified 39 genera with known crop plants in this geographical and historical context that are currently absent from its archaeobotanical record, constituting ‘orphan’ crops of archaeobotany. In addition, a worldwide synthesis of crop species studied using geometric morphometric, archaeogenetic and stable isotope analyses of archaeological plant remains is presented, and biases in the species represented in these disciplines are discussed. Both disciplinary methodological biases and economic agenda-based biases affecting species representativeness in crop history research are apparent. This study also highlights the limited geographic diffusion of most crops and the potential for deeper historical perspectives on how crops become marginalized and ‘forgotten’

Flashbulb memories for expected events: a test of the emotional-integrative model

Flashbulb memories (FBMs) are vivid, long-lasting and consistent recollections for the reception context of shocking and unexpected public news. Only a few studies have assessed FBMs for predictable events. In the present study the emotional-integrative model is considered to account for FBMs for an expected event, that is, the death of President Mitterrand, across two national groups, that are, French and Belgian citizens. Results showed that FBMs can develop for an expected event; they are affected by its emotional impact and subsequent rehearsal, while surprise did not play a role in their formation. The emotional-integrative model was confirmed as a promising tool to model datasets on FBMs. It holds for both subsamples, with a better parsimony for Belgian respondents' data. Implications for the debate about the nature of FBMs are discussed. Copyright © 2008 John Wiley & Sons, Ltd.FLWINinfo:eu-repo/semantics/publishe

Retraining Automatic Action Tendencies Changes Alcoholic Patients’ Approach Bias for Alcohol and Improves Treatment Outcome

Item does not contain fulltextThis study tested the effects of a new cognitive-bias modification (CBM) intervention that targeted an approach bias for alcohol in 214 alcoholic inpatients. Patients were assigned to one of two experimental conditions, in which they were explicitly or implicitly trained to make avoidance movements (pushing a joystick) in response to alcohol pictures, or to one of two control conditions, in which they received no training or sham training. Four brief sessions of experimental CBM preceded regular inpatient treatment. In the experimental conditions only, patients’ approach bias changed into an avoidance bias for alcohol. This effect generalized to untrained pictures in the task used in the CBM and to an Implicit Association Test, in which alcohol and soft-drink words were categorized with approach and avoidance words. Patients in the experimental conditions showed better treatment outcomes a year later. These findings indicate that a short intervention can change alcoholics’ automatic approach bias for alcohol and may improve treatment outcome.8 p

Considering planned change anew: stretching large group interventions strategically, emotionally and meaningfully

Large Group Interventions, methods for involving “the whole system” in a change process, are important contemporary planned organizational change approaches. They are well known to practitioners but unfamiliar to many organizational researchers, despite the fact that these interventions address crucial issues about which many organizational researchers are concerned. On the other hand, these interventions do not appear to be informed by contemporary developments in organizational theorizing. This disconnect on both sides is problematic. We describe such interventions and their importance; illustrate them with extended descriptions of particular Future Search and Whole‐Scale™ change interventions; summarize research on strategy, emotion, and sensemaking that may inform them; and suggest questions about the interventions that may stimulate research and reflection on practice. We also discuss conditions that may foster effective engagement between Large Group Interventions practitioners and organizational researchers. Our approach represents a way to conduct a review that combines scholarly literature and skilled practice and to initiate a dialog between them
