Over the past several decades, policy has become increasingly global. In economics, for example, policy has followed the so-called Washington Consensus of privatization, liberalization, and deregulation. In education, global policy has included the proliferation of strategies including standardized testing, paraprofessional teachers, user fees, and privatization. There are many problems with these neoliberal policies. Foremost among them, is the havoc they wreak on the lives of so many children and adults. Poverty, inequality, and myriad associated problems have reached new heights in this neoliberal era. Moreover, these policies have been adopted uncritically and alternative policies have been ignored, which leads to our focus here.

Extending recent research on the importance of specific resources and skills for the internationalization of start-ups, this article tests a negative binomial model on a sample of 520 recently created high technology firms from the UK and Germany. The results show that previous international experience of entrepreneurs facilitates the rapid penetration of foreign markets, especially when the company features a clear and deliberate strategic intent of internationalization from the outset. This research provides one of the first empirical studies linking the influence of entrepreneurial teams to a high probability of success in the internationalization of high-technology ventures.

How to Improve Pupils' Literacy? A Cost-Effectiveness Analysis of the Action Lecture This article presents a cost-effectiveness analysis of an innovative teaching method run in some nursery and primary schools in Paris. This project, named Action Lecture, is designed to improve pupils' abilities and taste on literacy. We report the results of an evaluation of this program. We describe the experimental protocol that was built to estimate the program's impact on several types of indicators (academic abilities, attitude toward reading, school life) by comparing the evolution of treatment schools and control schools. Data were processed following a Differences-in-Differences (DID) method. Then we use the estimation of the impact on academic achievement to conduct a cost-effectiveness analysis and take a reduction of the class size program as a benchmark. The results are positive for the Action Lecture program both in terms of impact's evaluation and in terms of cost-effectiveness ratio.

L'intérêt suscité par la ré-ingénierie des processus et les technologies de l'information révèle l'émergence du paradigme du management par les processus. Bien que beaucoup d'études aient été publiées sur des outils et techniques alternatives de modélisation de processus, peu d'attention a été portée à l'évaluation post-hoc des activités de modélisation de processus ou à l'établissement de directives sur la façon de conduire efficacement une modélisation de processus. La présente étude a pour objectif de combler ce manque. Nous présentons les résultats d'une étude de cas détaillée, conduite dans une organisation leader australienne dans le but de construire un modèle de réussite de la modélisation des processus.

Numerous crops grow in sugar regions that have the potential to increase the amount of biomass available to a small bagasse-based pulp factory. Arundo donax and Sorghum offer unique advantages to farmers compared to other agricultural crops. Sorghum bicolour requires only 1/3 of the water of sugarcane. Arundo donax is a very high yield crop, it can also grow with little water but it has the further advantage in that it is also highly stress tolerant, making it suitable for land which is unsuited to other crops. Pulps produced from these crops were benchmarked against sugarcane bagasse pulp. Arundo, sorghum and bagasse were pulped using KOH and anthraquinone to 20 Kappa number so as to produce a bleachable pulp which is suitable for making photocopier paper and tissue products. The unbleached sorghum pulp has better tensile strength properties than the unbleached Arundo pulp (43.8 Nm/g compared to 21.4 Nm/g) and the bleached sorghum pulp tensile strength was similar to bagasse (28.4 Nm/g). At 20 Kappa number, sorghum pulp had acceptable yield for a non-wood fibre (45% c.f. 55% for bagasse), Arundo donax pulp had low tensile strength, and relatively low yield (38.7%), even for an agricultural fibre and required severe cooking conditions to achieve similar delignification to sugarcane bagasse or sorghum. Sorghum and Arundo donax produced thicker handsheets than bagasse (>160 µm c.f. 122 µm for bagasse). In preliminary experiments sorghum and bagasse responded slightly better to Totally Chlorine Free peroxide bleaching (QPP), although none achieved a satisfactory brightness level and further improvement would be required to produce a bleached pulp.

This paper sets out to contribute to the literature on the design and the implementation of management control systems. To this end, we question what is discussed when a management control system is to be chosen and on what decision-making eventually rests. This study rests upon an ethnomethodology of the Salvation Army’s French branch. Operating in the dual capacity of a researcher and a counsellor to management, between 2000 and 2007, we have unrestricted access to internal data revealing the backstage of management control: discussions and interactions surrounding the choosing of control devices. We contribute to understanding the arising of a need for control, the steps and process followed to decide upon a management control system, and controls in nonprofits. [Cet article vise à contribuer à la littérature sur la mise en place des systèmes de contrôle de gestion. À cette fin, nous questionnons ce qui est discuté lors du choix d’un système de contrôle et sur quoi repose in fine la décision. Cet article est fondé sur une approche ethnométhodologique de l’Armée du Salut en France permise par notre double qualité de chercheurs mais également de conseiller auprès de la direction de l’organisation entre 2000 et 2007. Un accès illimité à des données internes nous permet ainsi de mettre en lumière les aspects méconnus et invisibles du contrôle de gestion : les discussions et interactions entourant le choix d’outils. Nous contribuons à la compréhension de l’émergence du besoin de contrôle, des étapes et du processus de choix d’outils et enfin du contrôle de gestion dans une organisation à but non lucratif.]

Quantum-like models can be fruitfully used to model attitude change in a social context. Next steps require data, and higher dimensional models. Here, we discuss an exploratory study that demonstrates an order effect when three question sets about Climate Beliefs, Political Affiliation and Attitudes Towards Science are presented in different orders within a larger study of n=533 subjects. A quantum-like model seems possible, and we propose a new experiment which could be used to test between three possible models for this scenario.

Abstract - English Multiple literacies refers to reading, reading the world and self. This article proposes an understanding of reading that goes beyond its definition in psychology and applied linguistics. This longitudinal project is interested in a conceptualisation of what reading is, how it functions and what it produces in becoming multilingual. Reading is explored through the lens of an empirical study involving five female pupils from senior Kindergarten to Grade 3 observed and interviewed in relation to activities at school and at home. The study took place in Ottawa schools where French is the sole language of instruction. Reading in the context of multiple literacies is conceptualised to disrupt /deterritorialise and to be immanent, offering the potentiality to go beyond what is to what could be. Becoming multilingual is a continuous movement involving networks of rhizomatic connections and reading the world and self. Résumé - Francais Les littératies multiples se réfèrent à la lecture, la lecture du monde et la lecture de soi. Cet article propose une compréhension de la lecture qui dépasse sa définition usuelle en psychologie et en linguistique appliquée. Ce projet longitudinal porte sur la conceptualisation de la lecture, son fonctionnement et ce qu’elle produit dans le devenir plurilingue. La lecture est examinée selon l’optique d’une étude empirique durant laquelle cinq écolières du jardin d’enfants à la 3e année étaient observées et interviewées par rapport à des activités à l’école et à la maison. L’étude a eu lieu dans des écoles d’Ottawa dont la seule langue d’enseignement est le français. Dans le contexte des littératies multiples, la lecture est conceptualisée comme étant perturbatrice/déterritorialisante et immanente. Elle offre la potentialité d’aller au-delà de ce qui est vers ce qui pourrait être. Devenir plurilingue est un mouvement continu faisant appel à des réseaux de connexions rhizomatiques et à la lecture du monde et de soi.

Meat/meat alternatives (M/MA) are key sources of Fe, Zn and protein, but intake tends to be low in young children. Australian recommendations state that Fe-rich foods, including M/MA, should be the first complementary foods offered to infants. The present paper reports M/MA consumption of Australian infants and toddlers, compares intake with guidelines, and suggests strategies to enhance adherence to those guidelines. Mother–infant dyads recruited as part of the NOURISH and South Australian Infants Dietary Intake studies provided 3 d of intake data at three time points: Time 1 (T1) (n 482, mean age 5·5 (SD 1·1) months), Time 2 (T2) (n 600, mean age 14·0 (SD 1·2) months) and Time 3 (T3) (n 533, mean age 24 (SD 0·7) months). Of 170 infants consuming solids and aged greater than 6 months at T1, 50 (29 %) consumed beef, lamb, veal (BLV) or pork on at least one of 3 d. Commercial infant foods containing BLV or poultry were the most common form of M/MA consumed at T1, whilst by T2 BLV mixed dishes (including pasta bolognaise) became more popular and remained so at T3. The processed M/MA increased in popularity over time, led by pork (including ham). The present study shows that M/MA are not being eaten by Australian infants or toddlers regularly enough; or in adequate quantities to meet recommendations; and that the form in which these foods are eaten can lead to smaller M/MA serve sizes and greater Na intake. Parents should be encouraged to offer M/MA in a recognisable form, as one of the first complementary foods, in order to increase acceptance at a later age.

Haemagglutinin (HA) and fusion (F) proteins of peste-des-petits-ruminants virus (PPRV) and rinderpest virus (RPV) were purified by immunoaffinity chromatography. The purified proteins were characterized by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate (SDS-PAGE). Rabbit hyperimmune sera were raised against the purified HA and F proteins and assayed by enzyme-linked immunosorbent assay (ELISA), haemagglutination-inhibition (HAI) and virus neutralization (VN) tests. The immunized animals were challenged with a virulent lapinized (rabbit-adapted) strain of RPV: Both HA and F proteins of PPRV protected rabbits against a lethal challenge with lapinized RPV. As expected, RPV HA and F proteins also conferred a similar protection against the homologous challenge. The postchallenge antibody responses were of a true anamnestic type.

The work integrates research in the language and terminology of various fields with lexicography, etymology, semantics, word formation, and pragmatics. Additionally, examination of German and Finnish provides the work with perspective of contrastive linguistics and the translation of texts in specialized fields. The work is an attempt to chart the language, vocabulary, different textual types, and essential communication-connected features of this special field. The study is primary concerned with internal communication within the field of ecology, but it also provides a comparison of the public discussion of environmental issues in Germany and Finland. The work attempts to use textual signs to provide a picture of the literary communication used on the different vertical levels in the central text types within the field. The dictionaries in the fields of environmental issues and ecology for the individual text types are examined primarily from the perspective of their quantity and diversity. One central point of the work is to clarify and collect all of the dictionaries in the field that have been compiled thus far in which German and/or Finnish ware included. Ecology and environmental protection are closely linked not only to each other but also to many other scientific fields. Consequently, the language of the environmental field has acquired an abundance of influences and vocabulary from the language of the special fields close to it as well as from that of politics and various areas of public administration. The work also demonstrates how the popularization of environmental terminology often leads to semantic distortion. Traditionally, scientific texts have used the smallest number of expressions, the purpose of which is to appeal to or influence the behavior of the text recipient. Particularly in Germany, those who support or oppose measures to protect the environment have long been making concerted efforts to represent their own views in the language that they use. When discussing controversial issues competing designations for the same referent or concept are used in accordance with the interest group to which the speaker belongs. One of the objectives of the study is to sensitize recipients of texts to notice the euphemistic expressions that occur in German and Finnish texts dealing with issues that are sensitive from the standpoint of environmental policy. One particular feature of the field is the wealth and large number of variants designating the same entry or concept. The terminological doublets formed by words of foreign origin and their German or Finnish language equivalents are quite typical of the field. Methods of corpus linguistics are used to determine the reasons for the large number of variant designations as well as their functionality.

Valency Realization in Short Excerpts of News Text. A Pragmatics-funded analysis This dissertation is a study of the so-called pragmatic valency. The aim of the study is to examine the phenomenon both theoretically by discussing the research literature and empirically based on evidence from a text corpus consisting of 218 short excerpts of news text from the German newspaper Frankfurter Allgemeine Zeitung. In the theoretical part of the study, the central concepts of the valency and the pragmatic valency are discussed. In the research literature, the valency denotes the relation among the verb and its obligatory and optional complements. The pragmatic valency can be defined as modification of the so-called system valency in the parole, including non-realization of an obligatory complement, non- realization of an optional complement and realization of an optional complement. Furthermore, the investigation of the pragmatic valency includes the role of the adjuncts, elements that are not defined by the valency, in the concrete valency realization. The corpus study investigates the valency behaviour of German verbs in a corpus of about 1500 sentences combining the methodology and concepts of valency theory, semantics and text linguistics. The analysis is focused on the about 600 sentences which show deviations from the system valency, providing over 800 examples for the modification of the system valency as codified in the (valency) dictionaries. The study attempts to answer the following primary question: Why is the system valency modified in the parole? To answer the question, the concept of modification types is entered. The modification types are recognized using distinctive feature bundles in which each feature with a negative or a positive value refers to one reason for the modification treated in the research literature. For example, the features of irrelevance and relevance, focus, world and text type knowledge, text theme, theme-rheme structure and cohesive chains are applied. The valency approach appears in a new light when explored through corpus-based investigation; both the optionality of complements and the distinction between complements and adjuncts as defined in the present valency approach seem in some respects defective. Furthermore, the analysis indicates that the adjuncts outside the valency domain play a central role in the concrete realization of the valency. Finally, the study suggests a definition of pragmatic valency, based on the modification types introduced in the study and tested in the corpus analysis.
