Emerging Identities in Colonial Tunisia: "Alliancist" and Zionist Representations in Tunis prior to World War I

By 1900 the Jewish community of Tunisia witnessed the emergence of new competing identities: “assimilationist” of the Alliance Israelite Universelle, termed “Alliancist,” and Zionist. Strikingly, two members of the same family in Tunis, Raymond Valensi, President of the AIU Regional Committee, and Alfred Valensi, President of the Zionist Federation, led the struggle for their separate causes. In his discussion of identity in the modern world, Homi Bhabha asks, "How do strategies of representation or empowerment come to be formulated in the competing claims of communities…where, despite shared histories of …discrimination, the exchange of values, meanings and priorities…may be profoundly antagonistic…?" It is in this context that the claims of the Alliance and Zionism will be examined prior to World War I, based on the Archives of the AIU and on such secondary sources as the indispensable work of Paul Sebag. The tensions between the Alliancists and Zionists continued until the outbreak of World War II, as the French-speaking Jews of Tunisia sought to define their individual and collective identities.

The Basque Diaspora in Latin America: Euskal Etxeak, Integration, and Tensions. EDAP 1/2016

The establishment of the Basque diaspora in Latin America can be divided in several different periods. First, from the 16th to 18th century, the so-called original diaspora of Basques who were part of the Spanish colonial regime. The second can be traced to the 19th century, consisting of a mixture of impoverished Basque migrants seeking jobs, especially in Uruguay and Argentina, and of refugees fleeing from the Spanish War of Independence and the Carlist wars. The third wave is identified by, but not only through, the considerable amount of refugees from the Spanish Civil War on the 1930's. The fourth wave came during the 1970s, with refugees from the Franco Dictatorship, ETA members and sympathisers. In this paper I will argue that each new wave of migrants brought tension to the diaspora, with the Euskal Etxeak, or ‘Basque houses’, as a focus point. The main idea is to analyse the different tensions and political discussions of this set of diasporic waves in Latin America.

'I could do with a pair of wings': Perspectives on physical activity, bodies and health from young Australian children

There is little research that reports children's perspectives on physical activity, bodies and health. This paper, drawn from a larger multi-method study on physical activity in the lives of seven- and eight-year-old Australian children, attempts to 'give a voice' to 13 children's views. Interviews focused on children's activity preferences and related decision making and motivations pertaining to these activities, as well as how they thought about the relationships between physical activity, health and their bodies. Data suggest some tensions surrounding the importance of fun for children alongside their awareness of 'healthist' discourses that require self-monitoring and improvement.

Identifying (territorial) tensions in the servitization value chain

Purpose: To understand the tensions that servitization activities create between actors within networks. Design/methodology/approach: Interviews were conducted with manufacturers, intermediaries and customers across a range of industrial sectors. Findings: Tensions relating to two key sets of capabilities are identified: in developing or acquiring (i) operant technical expertise and (ii) operand service infrastructure. The former tension concerns whom knowledge is co-created with and where expertise resides. The latter involves a territorial investment component; firms developing strategies to acquire greater access to, or ownership of, infrastructures closer to customers. Developing and acquiring these capabilities is a strategic decision on the part of managers of servitizing firms, in order to gain recognized power and control in a particular territory. Originality/value: This paper explores how firms’ servitization activities involve value appropriation (from the rest of the network), contrasting with the narrative norm for servitization: that it creates additional value. There is a need to understand the tensions that servitization activities create within networks. Some firms may be able to improve servitization performance through co-operation rather than competition, generating co-opetitive relationships. Others may need to become much more aggressive, if they are to take a greater share of the ‘value’ from the value chain.

Dissidents with an innovation cause? Non-institutionalized actors’ online social knowledge sharing, solution-finding tensions and technology management innovation

Purpose – Traditionally, most studies focus on institutionalized management-driven actors to understand technology management innovation. The purpose of this paper is to argue that there is a need for research to study the nature and role of dissident non-institutionalized actors’ (i.e. outsourced web designers and rapid application software developers). The authors propose that through online social knowledge sharing, non-institutionalized actors’ solution-finding tensions enable technology management innovation. Design/methodology/approach – A synthesis of the literature and an analysis of the data (21 interviews) provided insights in three areas of solution-finding tensions enabling management innovation. The authors frame the analysis on the peripherally deviant work and the nature of the ways that dissident non-institutionalized actors deviate from their clients (understood as the firm) original contracted objectives. Findings – The findings provide insights into the productive role of solution-finding tensions in enabling opportunities for management service innovation. Furthermore, deviant practices that leverage non-institutionalized actors’ online social knowledge to fulfill customers’ requirements are not interpreted negatively, but as a positive willingness to proactively explore alternative paths. Research limitations/implications – The findings demonstrate the importance of dissident non-institutionalized actors in technology management innovation. However, this work is based on a single country (USA) and additional research is needed to validate and generalize the findings in other cultural and institutional settings. Originality/value – This paper provides new insights into the perceptions of dissident non-institutionalized actors in the practice of IT managerial decision making. The work departs from, but also extends, the previous literature, demonstrating that peripherally deviant work in solution-finding practice creates tensions, enabling management innovation between IT providers and users.

Population and Government in Colonial Buenos Aires. An Approach to the Study of the Tensions Generated by Demographic Growth in the City (1740-1776)

The relationship between population and government in the City of Buenos Aires is analyzed, focusing on the tensions generated by the arrival of new individuals, a local elite with great interests in commerce and in charge of community affairs, and Spanish functionaries that progressively adopted the ideals of the Bourbon Dynasty, despite also being implicated in local logics. It interests us to observe the governors’ perspectives with respect to everyday developments in the city, their preoccupations and interests, and how they would vary the mechanisms to which they resorted in order to organize daily life, in the period defined between 1740 and 1776.

Lärares ledarskap som möjliggörande och begränsande i mötet med ’alla’ barn : En deltagarorienterad studie

The aim of this thesis is to, based on teachers’ experiences, describe and analyse meanings of teachers’ leadership in general, and in relation to children in need of special support in particular. The study was carried out within the tradition of participatory-oriented research, a research circle. The dialogues in the circle were based on the participants’ questions, experiences, interests, and knowledge. The circle included a researcher and nine teachers from the following types of schools: preschool, preschool class, compulsory school, and compulsory school for pupils with learning disabilities. The study is based on an understanding of leadership as a relational practice. Leadership is practised in the interaction between teacher and child. Both parties exert influence over the practice of leadership. A central assumption in the study is that knowledge can develop through and in interactions between people, that knowledge and power are connected, and that knowledge and actions are intertwined. Another central assumption is that learning is a complex phenomenon. In the analysis of the research circle’s dialogues, the following meanings of teachers’ leadership emerge: to facilitate learning and discipline, and to promote different interests. The practice of leadership involves teachers handling complex situations in their interactions with ‘all’ children, i.e. children in need of special support and children without such needs. Leadership is practised between teachers and children, and the teachers have to consider the group of children as a collective in relation to the individual children. At the same time, the teachers have to consider their intentions versus what happens during the interactions. In addition, the teachers have to pay heed to the fact that their own actions and the children’s actions influence one another. Finally, the teachers have to consider the individual child’s ‘best interest’ in relation to the requirements of the policy documents. Furthermore, the results indicate that the practice of leadership is perceived as both unpredictable and, to some extent, predictable at the same time, which adds to the complexity of leadership. The teachers cannot know for sure what the children understand or if the children’s actions facilitate learning. However, the teachers can make certain assumptions about how to practice leadership in order to facilitate learning and discipline in children with different needs. The meanings of leadership were expressed in different ways in the circle’s dialogues; both as enabling and limiting in interactions with children in need of special support. One of the study’s conclusions is that leadership seems to be particularly complex in interactions with children in need of special support. The research circle’s dialogues served to promote a democratic knowledge process. The dialogues were characterised by respect for the participants’ different opinions; however, this does not mean that they were free from power structures.

Prostytucja w aspekcie prawnym i jej skutki psychiczno-społeczne

Zgodnie z art. 203 Kodeksu karnego zabronione jest uprawianie prostytucji. Jednakże prostytucja jest to powszechnie istniejące zjawisko – fakt społeczny. Istnieje wiele czynników, dzięki którym dziewczyny decydują się na taki, a nie inny sposób zarabiania pieniędzy. Obecnie także pojawiła się nowa jego forma, a mianowicie sponsoring. Prostytucja jako zjawisko nie jest społecznie szkodliwa. Problem pojawia się, gdy nasilają się przyczyny tego stanu rzeczy, m.in. zanikanie silnych więzi społecznych, głębokiej emocjonalności czy utrata poczucia tożsamości. Seks niewątpliwie jest dziedziną życia człowieka. O sposobie zaspokojenia popędowych napięć seksualnych, a także o poziomie osiąganej przy tym satysfakcji nie decydują funkcje narządów płciowych, a cała osobowość. Seks pełni różne funkcje, a mianowicie psychologiczną, społeczną i biologiczną. Społeczeństwa były różnie nastawione do zjawiska prostytucji. Przez jednych była ona społeczne akceptowana, zaś przez drugich surowo represjonowana. Prostytucja w świetle prawa karnego oznacza nierząd prowadzony w celu osiągnięcia zysku. Także w związku z prostytucją jest karalne stręczycielstwo, kuplerstwo i sutenerstwo. Następstwa prostytucji mogą być psychologiczne i psychiatryczne. Pierwsze z nich polegają na tym, że młoda kobieta nie zdaje sobie sprawy z konsekwencji jakie mogą być po zdecydowaniu się na taką formę pracy, nie ma świadomości jak obciąża swoją psychikę. Kobiety mają do czynienia z przemocą i brutalnością w tym zawodzie, są upokarzane i wyszydzane przez klientów. Drugie natomiast polegają na tym, że kobieta sama do siebie traci szacunek, a potem zaczyna nawet siebie nienawidzić. Nawet jeśli kobieta z tym zerwie, pozostaje w niej poczucie winy i trauma wstydliwej przeszłości. Istnieją natomiast międzynarodowe regulacje prawne związane ze zjawiskiem prostytucji. Jedną z nich jest Konwencja ONZ w sprawie Eliminacji Wszelkich form Dyskryminacji Kobiet i druga Konwencja ONZ w sprawie Zwalczania Handlu Ludźmi i Eksploatacji Prostytucji.

I “resabios” come sovversione. Etnostoria dei movimenti di indigeni, donne e lavoratori nello «Stato apparente» boliviano

La tesi adotta una prospettiva etnostorica rafforzata da una metodologia etnografica per analizzare lo sviluppo dei processi di politicizzazione nel territorio boliviano dal periodo coloniale ad oggi, collocandoli all’interno di un più ampio sistema di relazioni economiche, politiche e sociali dettate dall’eterogeneo sviluppo del capitalismo globale; la tesi mostra sia il modo specifico in cui, nelle varie contingenze storiche, queste relazioni hanno riorganizzato l’«abigarrada» società boliviana e inciso sui processi di politicizzazione, sia il modo in cui i soggetti hanno contestato e messo in tensione tale riorganizzazione. Per l’analisi si partirà dalla posizione di quei soggetti che sono stati definiti alternativamente come indios, indigeni, campesinos nel territorio boliviano, guardando alle connessioni politiche che questi hanno messo in campo con diversi soggetti – donne, lavoratori, attivisti urbani. Questa posizione offre una «prospettiva epistemologica privilegiata» per indagare il modo in cui i movimenti sociali impattano nell’articolazione tra Stato, società civile e capitale, non perché tali soggetti sono portatori di un’autenticità alternativa al capitalismo, ma perché il modo in cui riattivano quell’insieme di miti, credenze e residui precapitalistici – i «resabios» – che concorrono alla «memoria larga» delle lotte, innestandoli su elementi introdotti dal capitalismo, mostra la loro capacità di sovvertire la posizione subalterna che la riproduzione del capitale nel territorio boliviano ha imposto loro. Si mostreranno anche le tensioni e i conflitti dati dalle diverse posizioni che donne e uomini, giovani e anziani, figure d’autorità e ‘base’ assumono all’interno della loro identificazione come indigeni. La ricerca permette di affermare che l’identità indigena è il prodotto della risposta istituzionale che di volta in volta è stata data per neutralizzare l’emergenza politica di soggetti la cui eterogeneità non ha impedito, ma al contrario ha reso possibile, un’accumulazione di forza tale da mettere in crisi gli assetti politici, economici e istituzionali dello Stato post-coloniale.

An Isoflavone From Dipteryx Alata Vogel Is Active Against The In Vitro Neuromuscular Paralysis Of Bothrops Jararacussu Snake Venom And Bothropstoxin I, And Prevents Venom-induced Myonecrosis.

Snakebite is a neglected disease and serious health problem in Brazil, with most bites being caused by snakes of the genus Bothrops. Although serum therapy is the primary treatment for systemic envenomation, it is generally ineffective in neutralizing the local effects of these venoms. In this work, we examined the ability of 7,8,3'-trihydroxy-4'-methoxyisoflavone (TM), an isoflavone from Dipteryx alata, to neutralize the neurotoxicity (in mouse phrenic nerve-diaphragm preparations) and myotoxicity (assessed by light microscopy) of Bothrops jararacussu snake venom in vitro. The toxicity of TM was assessed using the Salmonella microsome assay (Ames test). Incubation with TM alone (200 μg/mL) did not alter the muscle twitch tension whereas incubation with venom (40 μg/mL) caused irreversible paralysis. Preincubation of TM (200 μg/mL) with venom attenuated the venom-induced neuromuscular blockade by 84% ± 5% (mean ± SEM; n = 4). The neuromuscular blockade caused by bothropstoxin-I (BthTX-I), the major myotoxic PLA2 of this venom, was also attenuated by TM. Histological analysis of diaphragm muscle incubated with TM showed that most fibers were preserved (only 9.2% ± 1.7% were damaged; n = 4) compared to venom alone (50.3% ± 5.4% of fibers damaged; n = 3), and preincubation of TM with venom significantly attenuated the venom-induced damage (only 17% ± 3.4% of fibers damaged; n = 3; p < 0.05 compared to venom alone). TM showed no mutagenicity in the Ames test using Salmonella strains TA98 and TA97a with (+S9) and without (-S9) metabolic activation. These findings indicate that TM is a potentially useful compound for antagonizing the neuromuscular effects (neurotoxicity and myotoxicity) of B. jararacussu venom.
