Short Abstract Stemming from the ethnographic material collected during an eighteen months fieldwork conducted among a group Moroccan of women in Milan to study their food practices, this paper focuses on the materiality of cooking and eating through adopting a micro-structural approach. Long Abstract Inspired by the work of Lévi-Strauss (1964) aimed at identifying the relationships of mutual intelligibility underlying some social and cultural facts such as the treatment of food, this paper will focus on the materiality of cooking and eating through adopting a micro-structural approach. The ethnographic data collected during an eighteen months fieldwork conducted among a group of Moroccan women in Milan to study their cooking and eating habits will be analysed by paying particular attention to the practices and elements that made the "alphabet" of Moroccan cuisine. This means that, if we considered dishes as complex sentences which can be deciphered by people that share a same language, we could try to identify the littlest components that made them happen. Which norms regulated the combination of ingredients? Which ways of cooking described this food culture? Which gestures and embodied knowledge seemed essential to give an intelligible cultural connotation to the cooking and eating of food? Which variations were admitted? The analysis of the actors' discourses and practices will show how Lévi-Strauss approach and model to the study of foodways can meet a material culture approach and still be relevant nowadays.

n the first volume of his Mythologiques, entitled The Raw and the Cooked, Claude Lévi-Strauss argued that the preparation of food is a form of language that reveals a society's structure. For Lévi-Strauss, the so-called culinary triangle of the raw, the rotten and the cooked represents a semantic field within which the various forms of transformation of food from nature into culture play a key role. Since Lévi-Strauss, following extensive changes to food production, preparation and consumption, the notion of cooking has become ever more diversified, and became increasingly contentious. Yet, the multiple ways of combining and processing ingredients still give social and cultural meanings to food and trigger the creation of sociabilities and belongings through its own destruction (Gell 1986). This panel aims to explore Levi-Strauss' legacy and evaluate its usefulness in today's context from different angles, ranging from domestic food preparation to industrial production and global circulations of food. To what extent can this concept still provide an interpretative framework of topical food issues? Which contemporary myths does it shed light on? How could it be deployed to read the history of food and link it to contemporary questions? This panel welcomes papers on the history of food preparation, contemporary food preparation, including debates in professional and multimedia circles, various forms of food production and the possible transformation of food within globalised food markets. Although mobilizing a classic anthropological theory, this panel aims to be interdisciplinary and to present a diverse range of analytical perspectives. [less ▲]

Previous research on vocal pitch accuracy revealed insights into the fundamentals of singing. However, most of the research on singing focused on the analysis of single voices, whereas few aYempts have been made to tackle the challenge of analyzing mulTtrack recordings of singing ensembles. In addiTon, singers have to adjust their way of singing with respect to a given venue’s acousTcal environment (e.g., small room vs. a comparaTvely large space like a church). If it is common that musical performances are greatly influenced by room acousTcs, studies on the effects of room acousTcal features during ensemble singing are rare. In order to invesTgate singing performances across various condiTons, we manipulated the singing condiTon (unison, canon, solo) as well as the acousTcal feedback by applying diverging virtual rooms. Three duets with female singers (N = 6) were asked to sing three different melodies using headset microphones to record each singer separately. Recordings took place in the communicaTon acousTc simulator (CAS) at the House of Hearing (Oldenburg, Germany) to be able to provide different simulated acousTcal spaces (i.e., cathedral, classroom, and dry condiTon) to the singers. ObjecTve measures were performed on each recording and confirmed that the singers sang the melodies with high precision (small pitch interval deviaTons) hardly affected by singing condiTons or by the type of acousTcal feedback. However, the singers tended to driH (larger deviaTons of the tonal center) when singing in canon compared to solo and unison singing. Overall, the analysis of the pitch accuracy showed a general effect of condiTon (i.e., unison, canon, solo), but no general effect of acousTcal feedback and no interacTon between the two variables under study.

In western music, a semitone constitutes a theoretical and perceptual boundary between tones and is defined as a unit for categorical perception of intervals (Burns & Ward, 1978). However, melodic perception does not rely exclusively on this category but also involves the notion of ‘correctness’. If we usually classify melodies as “in tune” or “out of tune” depending on the size of interval deviations (smaller than a semitone) along melodies, the transition between the two categories remains unclear. This study examines the process involved in pitch accuracy perception. Twenty-five participants identified melodies as “in tune” or “out of tune” and rated their confidence for each answer. The pitch manipulation consisted of the enlargement of an interval in 5 cent steps (from 0 to 50 cent deviation). The interval deviated was either a Major 2nd or a Perfect 4th and occurred in the middle or end of a 6-tone melody. The task was run twice, before and after an explicit definition of the two labels. Repeated measure ANOVAs were conducted to examine the effect of the deviation on the proportion of in- tune answers and on the confidence levels. For the participants who were able to learn the labels (n = 20), the proportion of in tune answers varies greatly according to the amplitude of the deviation and depended on the size of the interval manipulated. Associated with the confidence level measurement, the identification data support a categorical perception process. Interestingly, explicitly learning the labels increased the overall confidence but did not modify drastically the profile of the categories and the process behind the categorization. This study suggests that explicit learning is not necessary to develop higher order categories relative to “correctness”. Nevertheless, such a process seems limited to certain intervals. Further investigation of other intervals and individual differences seems promising to better understand the mechanisms underlying music perception. [less ▲]

A {\em pseudo-Boolean function} is a real-valued function $f(x)=f(x_1,x_2,\ldots,x_n)$ of $n$ binary variables, that is, a mapping from $\{0,1\}^n$ to $\mathbf R$. \emph{Nonlinear binary optimization problems} of the form \begin{equation}\label{eq:PBO} \min \{ f(x) : x \in \{0,1\}^n \}, \end{equation}, where $f$ is a pseudo-Boolean function expressed as a multilinear polynomial in its variables, are notoriously difficult. For a pseudo-Boolean function $f(x)$ on $\{0,1\}^n$, we say that $g(x,y)$ is a \emph{quadratization} of $f$ if $g(x,y)$ is a quadratic polynomial depending on $x$ and on $m$ \emph{auxiliary} binary variables $y_1,y_2,\ldots,y_m$ such that $f(x)= \min \{ g(x,y) : y \in \{0,1\}^m \} $ for all $x \in \{0,1\}^n$. By means of quadratizations, minimization of $f$ is reduced to minimization (over the extended set of variables) of the quadratic function $g(x,y)$. This is of practical interest because minimization of quadratic functions has been thoroughly studied for the last few decades, and much progress has been made in solving such problems exactly or heuristically. This talk addresses two main types of questions. First, we want to determine the minimum number of auxiliary $y$-variables required in a quadratization of an arbitrary function~$f$. This question is rather natural since the complexity of minimizing the quadratic function $g(x,y)$ heavily depends (among other factors) on the number of binary variables~$(x,y)$. We establish tight lower and upper bounds on the number of auxiliary variables needed in such a reformulation. Next, we determine more precisely the number of auxiliary variables required by quadratizations of \emph{symmetric} pseudo-Boolean functions $f(x)$, i.e., functions whose value only depends on the number of variables equal to~$1$.

La lutte contre le chômage de longue durée et l’exclusion sociale par un retour à l’emploi représentent des enjeux essentiels des politiques actives du marché du travail. C’est pourquoi, cette communication s’intéresse aux effets de l’intervention sociale sur les demandeurs d’emploi à partir de l’analyse de deux dispositifs d’activation situés en Belgique francophone : une Entreprise de Formation par le Travail et une agence de Titres-Services. Au moyen d’une étude qualitative reposant sur une soixantaine d’observations de situations d’interactions réalisée entre bénéficiaires et « travailleurs du social » (consultant, assistant social, formateur, etc.) et, d’une quarantaine d’entretiens semi-directifs, nous rendrons compte de l’action de ces deux dispositifs dans le domaine de l’insertion-socioprofessionnelle. Nous illustrerons combien, par l’articulation de politiques d’emploi à vocation universelle et de politiques particularistes destinées aux personnes les plus fragiles, ces dispositifs génèrent de véritables trappes à précarité. À terme, nous montrerons combien le maintien de ces dernières soulève la question du développement progressif d’un nouveau régime de protections, opérant a minima, voire par défaut, auprès des publics peu qualifiés face à la menace sourde que font peser le marché noir et, plus largement, l’informalité du travail.

In humans, self and memory processes interact as evidenced by the self reference (SRE) and self reference recollection effects (SRRE). However, in patients with Alzheimer’s disease (AD), this relationship can be disrupted. This was evidenced by impaired SRE and SRRE in AD for recognition of adjectives previously judged for self-relevance, as well as recall of names of people previously linked to the self. For both materials, a qualitative impairment of the recollective experience for the self-related items was also observed in AD. A neuroimaging approach suggested that reduced SRE is related to decreased grey matter volume in the lateral prefrontal cortex (lPFC). Thus, retrieval of recent self-related memories is impaired in relation to altered high-order processes in lPFC in AD. [less ▲]

This article recognizes rivers as cultural heritage landscapes, as an integral component of cities common heritage and an element of collective memory and identity. It is based on the consideration that analysis of the socio-spatial relationship between the river and urban structure at different historical period can further lead to knowledge about the river contribution in forming the identity and sense of place of an urban area. This knowledge can be used to inform urban conservation as well as development practices to support the integral spatial and cultural relation between the city and the river in order to maintain the character of river city. This article takes the historic core in the city of Tripoli, Lebanon as a case study where conservation practices have followed a monument centric approach focusing on the restoration of heritage buildings and sites and neglecting the cultural value of the Abu Ali River flowing through the city. It conducts a multi- dimensional morphological analysis that is based on archival review and field work to extract the social value of the river and its contribution to the urban morphology of the city.
