Plurilingualism vs multilingualism in early years of schooling: The rise of a critical cultural awareness in primary school

Since early 80s the Council of Europe has taken a great approach to teaching and learning of languages by encouraging plurilingual practices instead of multilingual practices, being these understood as the coexistence of several languages within a given society. In this context, we believe that once one learns many languages, one values one's native language, allowing one to understand it more clearly and to communicate with others on an equal footing and, more importantly, one also learns about other cultures. This is an issue of great importance in order to value and respect one's own and other cultures in the context of European integration. Considering this, in this article, we present two linked projects: a) the “PrimaLang” project, related teaching practices multilingual promoting critical cultural awarenessl in the 1st cycle of Portuguese Primary School System; b) the “Plurilingual” project, which refers to the design of a coursebook which stimulates the development of a plurilingual competence in the 1st cycle of Portuguese Primary School System. At the same time, we analyze some materials made by students and teachers in the projects to better understand their contribution under the InterNetwork Comenius Project

Uma API criptográfica para aplicações embarcadas

This document presents GEmSysC, an unified cryptographic API for embedded systems. Software layers implementing this API can be built over existing libraries, allowing embedded software to access cryptographic functions in a consistent way that does not depend on the underlying library. The API complies to good practices for API design and good practices for embedded software development and took its inspiration from other cryptographic libraries and standards. The main inspiration for creating GEmSysC was the CMSIS-RTOS standard, which defines an unified API for embedded software in an implementation-independent way, but targets operating systems instead of cryptographic functions. GEmSysC is made of a generic core and attachable modules, one for each cryptographic algorithm. This document contains the specification of the core of GEmSysC and three of its modules: AES, RSA and SHA-256. GEmSysC was built targeting embedded systems, but this does not restrict its use only in such systems – after all, embedded systems are just very limited computing devices. As a proof of concept, two implementations of GEmSysC were made. One of them was built over wolfSSL, which is an open source library for embedded systems. The other was built over OpenSSL, which is open source and a de facto standard. Unlike wolfSSL, OpenSSL does not specifically target embedded systems. The implementation built over wolfSSL was evaluated in a Cortex- M3 processor with no operating system while the implementation built over OpenSSL was evaluated on a personal computer with Windows 10 operating system. This document displays test results showing GEmSysC to be simpler than other libraries in some aspects. These results have shown that both implementations incur in little overhead in computation time compared to the cryptographic libraries themselves. The overhead of the implementation has been measured for each cryptographic algorithm and is between around 0% and 0.17% for the implementation over wolfSSL and between 0.03% and 1.40% for the one over OpenSSL. This document also presents the memory costs for each implementation.

Inércia organizacional

Ultimamente muitas investigações têm sido levadas a cabo em diferentes áreas das Ciências Sociais e Humanas, nas quais o fenómeno de inércia, suas causas e resultados têm sido estudados, a saber: na Filosofia (Ética e Praxeologia), na Psicologia ou na Teoria Organizacional. Todavia, parece que a literatura científica das Ciências Sociais, maioritariamente baseada em estudos empíricos, nos quais a inércia é uma das variáveis independentes, carece de reflexão teórica. O problema de inércia organizacional é analisado no presente artigo como um caso específico da inércia do comportamento humano. Este artigo aborda apenas algumas questões relacionadas com a inércia do comportamento humano: o problema da aplicação directa do princípio mecânico para a área psicossocial, algumas concepções deste fenómeno nas Ciências Sociais com especial enfoque na Teoria organizacional, bem como a avaliação deste fenómeno. Por estas razões, o texto concentra- se nos aspectos conceptuais do fenómeno, levantando mais questões do que dando respostas. Tem um carácter introdutório a futuras investigações.

Towards a Bourdieusian analysis of the disabled body and practice: embodying negative symbolic capitals and the uneasy experience of hysteresis

Within the last few years, disabled people have become the target of government austerity measures through drastic cuts to welfare justified through the portrayal of benefit claimants as inactive, problem citizens who are wilfully unemployed. For all that is wrong with these cuts, they are one of many aspects of exclusion that disabled people face. Attitudes towards disability are deteriorating (Scope, 2011) and disabled people are devalued and negatively positioned in a myriad of ways, meaning that an understanding of the perceptions and positioning of disability and the power of disabling practices is critical. This thesis will examine how Bourdieu’s theoretical repertoire may be applied to the area of Disability Studies in order to discern how society produces oppressive and exclusionary systems of classification which structures the social position and perceptions of disability. The composite nature of disability and multiple forms of exclusion and inequality associated with it benefits from a multipronged approach which acknowledges personal, embodied and psychological aspects of disability alongside socio-political and cultural conceptualisations. Bourdieu’s approach is one in which the micro and macro aspects of social life are brought together through their meso interplay and provides a thorough analysis of the many aspects of disability.

Sinterização de aço inoxidável reforçado com partículas nanométricas dispersas de carbeto de nióbio - NbC

Metal powder sintering appears to be promising option to achieve new physical and mechanical properties combining raw material with new processing improvements. It interest over many years and continue to gain wide industrial application. Stainless steel is a widely accepted material because high corrosion resistance. However stainless steels have poor sinterability and poor wear resistance due to their low hardness. Metal matrix composite (MMC) combining soft metallic matrix reinforced with carbides or oxides has attracted considerable attention for researchers to improve density and hardness in the bulk material. This thesis focuses on processing 316L stainless steel by addition of 3% wt niobium carbide to control grain growth and improve densification and hardness. The starting powder were water atomized stainless steel manufactured for Höganäs (D 50 = 95.0 μm) and NbC produced in the UFRN and supplied by Aesar Alpha Johnson Matthey Company with medium crystallite size 16.39 nm and 80.35 nm respectively. Samples with addition up to 3% of each NbC were mixed and mechanically milled by 3 routes. The route1 (R1) milled in planetary by 2 hours. The routes 2 (R2) and 3 (R3) milled in a conventional mill by 24 and 48 hours. Each milled samples and pure sample were cold compacted uniaxially in a cylindrical steel die (Ø 5 .0 mm) at 700 MPa, carried out in a vacuum furnace, heated at 1290°C, heating rate 20°C stand by 30 and 60 minutes. The samples containing NbC present higher densities and hardness than those without reinforcement. The results show that nanosized NbC particles precipitate on grain boundary. Thus, promote densification eliminating pores, control grain growth and increase the hardness values

Ammonium uptake, transport and nitrogen economy in forest trees

AMMONIUM UPTAKE, TRANSPORT AND NITROGEN ECONOMY IN FOREST TREES Francisco M. Cánovas, Concepción Avila, Fernando N. de la Torre, Rafael A. Cañas, Belén Pascual, Vanessa Castro- Rodríguez, Jorge El-Azaz Departamento de Biología Molecular y Bioquímica, Facultad de Ciencias, Universidad de Málaga, Spain. Email: canovas@uma.es Forests ecosystems play a fundamental role in the regulation of global carbon fixation and preservation of biodiversity. Forest trees are also of great economic value because they provide a wide range of products of commercial interest, including wood, pulp, biomass and important secondary metabolites. The productivity of most forest ecosystems is limited by low nitrogen availability and woody perennials have developed adaptation mechanisms, such as ectomycorrhizal associations, to increase the efficiency of N acquisition and metabolic assimilation. The efficient acquisition, assimilation and economy of nitrogen are of special importance in trees that must cope with seasonal periods of growth and dormancy over many years. In fact, the ability to accumulate nitrogen reserves and to recycle N is crucial to determine the growth and production of forest biomass. Ammonium is the predominant form of inorganic nitrogen in the soil of temperate forests and many research efforts are addressed to study the regulation of ammonium acquisition, assimilation and internal recycling for the biosynthesis of amino acids, particularly those relevant for nitrogen storage. In our laboratory, we are interested in studying nitrogen metabolism and its regulation in maritime pine (Pinus pinaster L. Aiton), a conifer species of great ecological and economic importance in Europe and for which whole-transcriptome resources are available. The metabolism of phenylalanine plays a central role in the channeling of carbon from photosynthesis to the biosynthesis of phenylpropanoids and the regulation of this pathway is of broad significance for nitrogen economy of maritime pine. We are currently exploring the molecular properties and regulation of genes involved in the biosynthesis and metabolic fates of phenylalanine in maritime pine. An overview of this research programme will be presented and discussed.

Interventions pédagogiques pour diminuer le niveau d’appréhension en entrevues enformation technique au Cégep

Abstract: Career programs in the Cegep system base their training on various learning activities, which are followed by a practicum. The objective is to achieve a certain number of competencies, deemed necessary by the Ministry of Education, for entry-level occupations in to the workforce. The Graphic Communications program offered at Champlain College Saint-Lambert is a three-year career program that leads to employment in the field of graphics. Many students have part-time jobs during their schooling period but most of those jobs do not relate to their field of study. Several graduates stated they were unable to persuade employers to hire them for an externship or stage at the end of their program. While jobs are important for their general skills, since they are not directly related to the field, these jobs may not have given the students a suitable model for the conduct of an employment interview. Practice interviews may be one of many successful training methods to lower communication apprehension (CA) levels. CA is defined as "an individual's level of fear or anxiety associated with either real or anticipated communication with another person or persons." This paper examines the literature on CA and employment interviews and evaluates whether pedagogical interventions, including monitored phone calls to employers and practice-videotaped interviews, allow students to feel more confident about interviewing for a future job. A qualitative tool was used to gather scientific measurements of the participants' levels of CA both at the beginning and at the end of the Career Planning course. Open-ended reflective journals gathered quantitative data on the impact specific instructional strategies had on the participants. The pedagogical interventions that were examined and tested were as follows: preparation of scripts, monitored phone calls, videotaped practice interviews, and in-class access to professional assistance. Results indicate that all interventions had a positive impact on lowering levels of CA. It is clear that positive conclusions were drawn by the students as to the usefulness of these activities. Overall, participants who responded to the reflective journal questions felt positive about the contribution of this preparatory career course to their CA levels. The results of the quantitative tool were consistent with previous research and the analysis of the reflective journals gave additional support to the usefulness of the interventions on students' confidence levels. Recommendations for improvements to the curriculum include the need for students to be taught formally about metacognition and how to monitor it. Students need to be exposed to videotaped interviews more often. They should be better prepared for unexpected interview questions, and they should experience formal rehearsals with one of their instructors before the actual practice interview. Some of these recommendations have already been successfully implemented in the program's curriculum.||Résumé: Le but de ce travail était de vérifier si certaines activités pédagogiques sont efficaces pour faire baisser le niveau d'anxiété lié à la communication orale lors de leurs entrevues d'embauche. L'objectif des programmes techniques au Québec est de fournir aux étudiants un certain nombre de compétences définies par le ministère de l'Éducation, des Loisirs et du Sport afin que ces derniers puissent fournir des services de techniciens spécialisés aux entreprises. Le programme nommé Office Systems Technology (412) du collège Champlain de Saint-Lambert, a choisi la voie de la spécialisation en microédition et hypermédia en 1999 et a changé son nom pour Graphic Communications en 2005. Les programmes techniques au Cégep incluent un stage en milieu de travail à la fin d'un programme de trois ans et par le fait même, une entrevue pour obtenir un stage en entreprise. La compétence visée par cette étude est l'intégration au marché du travail et le cheminement professionnel des étudiants. Lors d'enquêtes informelles, plusieurs étudiants du programme ont fait part de leurs difficultés à trouver un stage en fin d'études. Certains auteurs suggèrent que ces étudiants n'ont pas de modèles appropriés lors de la tenue d'une entrevue d'emploi. Ils proposent de diminuer le niveau d'anxiété lié à la communication orale lors d'entrevues d'embauche en offrant des pratiques d'entrevue aux étudiants. Cette recherche a examiné la littérature au sujet de l'anxiété de communication, plus précisément lors d'entrevues. Elle avait pour mandat d'évaluer si les activités pédagogiques d'un cours de préparation à la carrière ont été efficaces pour faire baisser les taux d'anxiété en communication orale lors d'entrevues. En plus, une conseillère à l'emploi fut invitée à plusieurs reprises afin de fournir un support professionnel en classe, étant donné que les étudiants ne prennent pas nécessairement le temps de consulter des professionnels en raison de leurs activités personnelles trop nombreuses. Le type d'enseignement évalué est considéré comme stratégique, étant donné qu'il agit au niveau cognitif et métacognitif de l'étudiant. Le cours de préparation à l'emploi débute par la vérification des acquis antérieurs des étudiants et il tient compte de leur motivation scolaire et professionnelle. De plus, il est axé sur la construction du savoir en proposant des activités de plus en plus complexes, débutant par la rédaction de textes à utiliser lors d'appels aux employeurs, en passant par la préparation et la pratique d'appels et se terminant par des entrevues d'emploi qui serviront de modèle à perfectionner par chaque étudiant. Ces entrevues se font avec des employeurs qui ont déjà embauché des étudiants du programme de Graphic Communications au collège Champlain de Saint-Lambert et sont enregistrées sur bande vidéo afin de permettre une visualisation ultérieure et cohérente avec les objectifs visés. La méthodologie de cette recherche inclut deux outils, un quantitatif et un qualitatif. L'outil quantitatif permet de mesurer scientifiquement les taux d'appréhension en communication des étudiants au début et à la fin du cours de préparation à l'emploi. Cet outil est la fusion de deux outils, le Personal Report of Communication Apprehension ou PRCA-24, qui fut développé par McCroskey (1984), en tandem avec celui de Wongprasert & Ayres (2000), qui lui met l'accent sur les entrevues d'emploi. Les réponses à cet outil combiné sont évaluées sur une échelle Likert de cinq points. L'outil qualitatif est une série de questions auxquelles les étudiants ont répondu quatre fois lors de la session. Les réponses à ces questions ont été analysées et les commentaires des étudiants évalués. Il découle de cette analyse que les niveaux d'anxiété des étudiants qui ont participé (14) étaient définitivement à la baisse en fin de cours. La pratique téléphonique structurée, dans un laboratoire avec les téléphones, a été très révélatrice pour les étudiants. Ils ont appris comment utiliser un script comme piste de départ pour un appel et qu'il était possible de contourner certains obstacles de façon professionnelle. Ensuite, lors d'une visite d'une compagnie de graphisme, ils ont pu observer divers modèles d'emploi. Ils ont eu la possibilité de poser des questions sur le fonctionnement et les besoins de l'entreprise. Ceci facilita la rédaction de leur curriculum vitae en leur permettant de mieux décrire leurs acquis en fonction d'emplois recherchés. Par la suite, ils se sont préparés pour une pratique d'entrevue, filmée. Les interviewers avaient déjà travaillé avec le collège et avaient déjà embauché certains étudiants de ce programme, donc ils connaissaient leur potentiel. Une liste de questions possibles fut suggérée mais il n'en restait pas moins que les interviewers pouvaient les modifier, ceci étant représentatif du marché de l'emploi. Même si le collège fournit un enseignement en anglais, un des intervieweurs donna ses entrevues en français. Trois étudiants se sont portés volontaires, mais deux ont constaté qu'ils auraient dû pratiquer leur script en français avant l'entrevue pour mieux diminuer leur niveau d'anxiété. Finalement, les étudiants durent visionner leur segment d'entrevue : ceci leur a permis de voir si leur attitude non-verbale concordait avec ce qu'ils ressentaient en entrevue et d'emmener les correctifs appropriés. Les taux d'anxiété furent vérifiés une deuxième fois en fin de session et les résultats ont démontré une baisse des taux d'appréhension. Les résultats de cette étude concordent donc avec ceux trouvés dans la littérature et donnent de bonnes pistes pour l'amélioration de ce cours de préparation à la carrière. L'auteur recommande d'enseigner la métacognition de façon formelle et ainsi de faciliter la prise de conscience des apprentissages que les étudiants effectuent. De plus, les étudiants devraient être filmés en studio au moins une fois par année pour diminuer le facteur de stress causé par les caméras et finalement ils pourraient certainement bénéficier de pratiques formelles d'entrevue avec un instructeur avant l'entrevue filmée. L'augmentation des pratiques a déjà été mise en oeuvre dans le programme et des résultats positifs se sont ensuivis.

Clickers in the nursing classroom.

Traditional teaching methods in the classroom also limit opportunities for student engagement due to large class sizes and the desire to ensure students receive all of the material required in a particular session. It has been documented that the use of Information Technolgy (IT); in particular «clickers», can increase student participation, improve knowledge retention and assist in stimulating critical thinking in a classroom setting. However, the introduction of IT, on top of normal teaching demands, can be probelmatic as it requires changes to course planners, IT training, support staff and additional funding, all of wich have been documented in research. Wolski and Jackson (1999) have postulated that success is a function of the usefulness and the ease of use of a particular technology for faculty members. Research has shown that classroom technology is simply a tool to be used by educators as one of many. Those who tend to use it well are already innovative and technically adept (Zhao, Pugh, Sheldon & Bryers, 2002).||Résumé : Les méthodes d'enseignement traditionnelles en cour magistral ont aussi tendance à limiter l'engagement et la participation des étudiants dû à la taille souvent excessive des classes, mais aussi à cause du désire de l'enseignant de vouloir s'assurer de la transmission du contenu pédagogique complet. Il est bien documenté que l'usage des nouvelles technologies, en particulier les télévoteurs («clickers», peut accroître la participation des étudiants, améliorer la rétention de l'information mais aussi de stimuler, dans le contexte académique, la pensée critique. Malheureusement, tel que démontré par la recherche, l'introduction de ces nouvelles technologies pose problème lorsqu'additionné aux contraintes normales d'enseignement puisque qu'elle nécessite des changements à la planification des cours, requiert une formation spécifique, un support additionnel ainsi que le financement nécessaire. Wolski and Jackson (1999) ont postulé de plus que le succès de l'implantation d'une nouvelle technologie était en fonction de son utilité et de sa facilité d'utilisation par les membres de la faculté. Il a aussi été démontré que la technologie de l'enseignement en classe n'était en fait qu'un outil de plus à la disposition des enseignants, et que ceux qui avaient tendance à bien l'utiliser étaient de fait inoovateurs, possédant des capacités techniques (Zhao, Pugh, Sheldon et Bryers, 2002).

Can the European Union build a bridge over troubled waters? An analysis of the politicised and depoliticised legal approach between the European Union and Cyprus

The Cyprus dispute accurately portrays the evolution of the conflict from ‘warfare to lawfare’ enriched in politics; this research has proven that the Cyprus problem has been and will continue to be one of the most judicialised disputes across the globe. Notwithstanding the ‘normalisation’ of affairs between the two ethno-religious groups on the island since the division in 1974, the Republic of Cyprus’ (RoC) European Union (EU) membership in 2004 failed to catalyse reunification and terminate the legal, political and economic isolation of the Turkish Cypriot community. So the question is; why is it that the powerful legal order of the EU continuously fails to tame the tiny troublesome island of Cyprus? This is a thesis on the interrelationship of the EU legal order and the Cyprus problem. A literal and depoliticised interpretation of EU law has been maintained throughout the EU’s dealings with Cyprus, hence, pre-accession and post-accession. The research has brought to light that this literal interpretation of EU law vis-à-vis Cyprus has in actual fact deepened the division on the island. Pessimists outnumber optimists so far as resolving this problem is concerned, and rightly so if you look back over the last forty years of failed attempts to do just that, a diplomatic combat zone scattered with the bones of numerous mediators. This thesis will discuss how the decisions of the EU institutions, its Member States and specifically of the European Court of Justice, despite conforming to the EU legal order, have managed to disregard the principle of equality on the divided island and thus prevent the promised upgrade of the status of the Turkish Cypriot community since 2004. Indeed, whether a positive or negative reading of the Union’s position towards the Cyprus problem is adopted, the case remains valid for an organisation based on the rule of law to maintain legitimacy, democracy, clarity and equality to the decisions of its institutions. Overall, the aim of this research is to establish a link between the lack of success of the Union to build a bridge over troubled waters and the right of self-determination of the Turkish Cypriot community. The only way left for the EU to help resolve the Cyprus problem is to aim to broker a deal between the two Cypriot communities which will permit the recognition of the Turkish Republic of Northern Cyprus (TRNC) or at least the ‘Taiwanisation’ of Northern Cyprus. Albeit, there are many studies that address the impact of the EU on the conflict or the RoC, which represents the government that has monopolised EU accession, the argument advanced in this thesis is that despite the alleged Europeanisation of the Turkish Cypriot community, they are habitually disregarded because of the EU’s current legal framework and the Union’s lack of conflict transformation strategy vis-à-vis the island. Since the self-declared TRNC is not recognised and EU law is suspended in northern Cyprus in accordance with Protocol No 10 on Cyprus of the Act of Accession 2003, the Turkish-Cypriots represent an idiomatic partner of Brussels but the relations between the two resemble the experience of EU enlargement: the EU’s relevance to the community has been based on the prospects for EU accession (via reunification) and assistance towards preparation for potential EU integration through financial and technical aid. Undeniably, the pre-accession and postaccession strategy of Brussels in Cyprus has worsened the Cyprus problem and hindered the peace process. The time has come for the international community to formally acknowledge the existence of the TRNC.

Fixed argument pairings

A common scenario in many pairing-based cryptographic protocols is that one argument in the pairing is fixed as a long term secret key or a constant parameter in the system. In these situations, the runtime of Miller's algorithm can be significantly reduced by storing precomputed values that depend on the fixed argument, prior to the input or existence of the second argument. In light of recent developments in pairing computation, we show that the computation of the Miller loop can be sped up by up to 37 if precomputation is employed, with our method being up to 19.5 faster than the previous precomputation techniques.

On democracy

If one clear argument emerged from my doctoral thesis in political science, it is that there is no agreement as to what democracy is. There are over 40 different varieties of democracy ranging from those in the mainstream with subtle or minute differences to those playing by themselves in the corner. And many of these various types of democracy are very well argued, empirically supported, and highly relevant to certain polities. The irony is that the thing which all of these democratic varieties or the ‘basic democracy’ that all other forms of democracy stem from, is elusive. There is no international agreement in the literature or in political practice as to what ‘basic democracy’ is and that is problematic as many of us use the word ‘democracy’ every day and it is a concept of tremendous importance internationally. I am still uncertain as to why this problem has not been resolved before by far greater minds than my own, and it may have something to do with the recent growth in democratic theory this past decade and the innovative areas of thought my thesis required, but I think I’ve got the answer. By listing each type of democracy and filling the column next to this list with the literature associated with these various styles of democracy, I amassed a large and comprehensive body of textual data. My research intended to find out what these various styles of democracy had in common and to create a taxonomy (like the ‘tree of life’ in biology) of democracy to attempt at showing how various styles of democracy have ‘evolved’ over the past 5000 years.ii I then ran a word frequency analysis program or a piece of software that counts the 100 most commonly used words in the texts. This is where my logic came in as I had to make sense of these words. How did they answer what the most fundamental commonalities are between 40 different styles of democracy? I used a grounded theory analysis which required that I argue my way through these words to form a ‘theory’ or plausible explanation as to why these particular words and not others are the important ones for answering the question. It came down to the argument that all 40 styles of democracy analysed have the following in common 1) A concept of a citizenry. 2) A concept of sovereignty. 3) A concept of equality. 4) A concept of law. 5) A concept of communication. 6) And a concept of selecting officials. Thus, democracy is a defined citizenry with its own concept of sovereignty which it exercises through the institutions which support the citizenry’s understandings of equality, law, communication, and the selection of officials. Once any of these 6 concepts are defined in a particular way it creates a style of democracy. From this, we can also see that there can be more than one style of democracy active in a particular government as a citizenry is composed of many different aggregates with their own understandings of the six concepts.

'Nothing exists for one cause' : putting biology back into evolution

The opening phrase of the title is from Charles Darwin’s notebooks (Schweber 1977). It is a double reminder, firstly that mainstream evolutionary theory is not just about describing nature but is particularly looking for mechanisms or ‘causes’, and secondly, that there will usually be several causes affecting any particular outcome. The second part of the title is our concern at the almost universal rejection of the idea that biological mechanisms are sufficient for macroevolutionary changes, thus rejecting a cornerstone of Darwinian evolutionary theory. Our primary aim here is to consider ways of making it easier to develop and to test hypotheses about evolution. Formalizing hypotheses can help generate tests. In an absolute sense, some of the discussion by scientists about evolution is little better than the lack of reasoning used by those advocating intelligent design. Our discussion here is in a Popperian framework where science is defined by that area of study where it is possible, in principle, to find evidence against hypotheses – they are in principle falsifiable. However, with time, the boundaries of science keep expanding. In the past, some aspects of evolution were outside the current boundaries of falsifiable science, but increasingly new techniques and ideas are expanding the boundaries of science and it is appropriate to re-examine some topics. It often appears that over the last few decades there has been an increasingly strong assumption to look first (and only) for a physical cause. This decision is virtually never formally discussed, just an assumption is made that some physical factor ‘drives’ evolution. It is necessary to examine our assumptions much more carefully. What is meant by physical factors ‘driving’ evolution, or what is an ‘explosive radiation’. Our discussion focuses on two of the six mass extinctions, the fifth being events in the Late Cretaceous, and the sixth starting at least 50,000 years ago (and is ongoing). Cretaceous/Tertiary boundary; the rise of birds and mammals. We have had a long-term interest (Cooper and Penny 1997) in designing tests to help evaluate whether the processes of microevolution are sufficient to explain macroevolution. The real challenge is to formulate hypotheses in a testable way. For example the numbers of lineages of birds and mammals that survive from the Cretaceous to the present is one test. Our first estimate was 22 for birds, and current work is tending to increase this value. This still does not consider lineages that survived into the Tertiary, and then went extinct later. Our initial suggestion was probably too narrow in that it lumped four models from Penny and Phillips (2004) into one model. This reduction is too simplistic in that we need to know about survival and ecological and morphological divergences during the Late Cretaceous, and whether Crown groups of avian or mammalian orders may have existed back into the Cretaceous. More recently (Penny and Phillips 2004) we have formalized hypotheses about dinosaurs and pterosaurs, with the prediction that interactions between mammals (and groundfeeding birds) and dinosaurs would be most likely to affect the smallest dinosaurs, and similarly interactions between birds and pterosaurs would particularly affect the smaller pterosaurs. There is now evidence for both classes of interactions, with the smallest dinosaurs and pterosaurs declining first, as predicted. Thus, testable models are now possible. Mass extinction number six: human impacts. On a broad scale, there is a good correlation between time of human arrival, and increased extinctions (Hurles et al. 2003; Martin 2005; Figure 1). However, it is necessary to distinguish different time scales (Penny 2005) and on a finer scale there are still large numbers of possibilities. In Hurles et al. (2003) we mentioned habitat modification (including the use of Geogenes III July 2006 31 fire), introduced plants and animals (including kiore) in addition to direct predation (the ‘overkill’ hypothesis). We need also to consider prey switching that occurs in early human societies, as evidenced by the results of Wragg (1995) on the middens of different ages on Henderson Island in the Pitcairn group. In addition, the presence of human-wary or humanadapted animals will affect the distribution in the subfossil record. A better understanding of human impacts world-wide, in conjunction with pre-scientific knowledge will make it easier to discuss the issues by removing ‘blame’. While continued spontaneous generation was accepted universally, there was the expectation that animals continued to reappear. New Zealand is one of the very best locations in the world to study many of these issues. Apart from the marine fossil record, some human impact events are extremely recent and the remains less disrupted by time.

Fatalism, superstition, religion, and culture : road user beliefs and behaviour in Pakistan

Road traffic crashes have emerged as a major health problem around the world. Road crash fatalities and injuries have been reduced significantly in developed countries, but they are still an issue in low and middle-income countries. The World Health Organization (WHO, 2009) estimates that the death toll from road crashes in low- and middle-income nations is more than 1 million people per year, or about 90% of the global road toll, even though these countries only account for 48% of the world's vehicles. Furthermore, it is estimated that approximately 265,000 people die every year in road crashes in South Asian countries and Pakistan stands out with 41,494 approximately deaths per year. Pakistan has the highest rate of fatalities per 100,000 population in the region and its road crash fatality rate of 25.3 per 100,000 population is more than three times that of Australia's. High numbers of road crashes not only cause pain and suffering to the population at large, but are also a serious drain on the country's economy, which Pakistan can ill-afford. Most studies identify human factors as the main set of contributing factors to road crashes, well ahead of road environment and vehicle factors. In developing countries especially, attention and resources are required in order to improve things such as vehicle roadworthiness and poor road infrastructure. However, attention to human factors is also critical. Human factors which contribute to crashes include high risk behaviours like speeding and drink driving, and neglect of protective behaviours such as helmet wearing and seat belt wearing. Much research has been devoted to the attitudes, beliefs and perceptions which contribute to these behaviours and omissions, in order to develop interventions aimed at increasing safer road use behaviours and thereby reducing crashes. However, less progress has been made in addressing human factors contributing to crashes in developing countries as compared to the many improvements in road environments and vehicle standards, and this is especially true of fatalistic beliefs and behaviours. This is a significant omission, since in different cultures in developing countries there are strong worldviews in which predestination persists as a central idea, i.e. that one's life (and death) and other events have been mapped out and are predetermined. Fatalism refers to a particular way in which people regard the events that occur in their lives, usually expressed as a belief that an individual does not have personal control over circumstances and that their lives are determined through a divine or powerful external agency (Hazen & Ehiri, 2006). These views are at odds with the dominant themes of modern health promotion movements, and present significant challenges for health advocates who aim to avert road crashes and diminish their consequences. The limited literature on fatalism reveals that it is not a simple concept, with religion, culture, superstition, experience, education and degree of perceived control of one's life all being implicated in accounts of fatalism. One distinction in the literature that seems promising is the distinction between empirical and theological fatalism, although there are areas of uncertainty about how well-defined the distinction between these types of fatalism is. Research into road safety in Pakistan is scarce, as is the case for other South Asian countries. From the review of the literature conducted, it is clear that the descriptions given of the different belief systems in developing countries including Pakistan are not entirely helpful for health promotion purposes and that further research is warranted on the influence of fatalism, superstition and other related beliefs in road safety. Based on the information available, a conceptual framework is developed as a means of structuring and focusing the research and analysis. The framework is focused on the influence of fatalism, superstition, religion and culture on beliefs about crashes and road user behaviour. Accordingly, this research aims to provide an understanding of the operation of fatalism and related beliefs in Pakistan to assist in the development and implementation of effective and culturally appropriate interventions. The research examines the influence of fatalism, superstition, religious and cultural beliefs on risky road use in Pakistan and is guided by three research questions: 1. What are the perceptions of road crash causation in Pakistan, in particular the role of fatalism, superstition, religious and cultural beliefs? 2. How does fatalism, superstition, and religious and cultural beliefs influence road user behaviour in Pakistan? 3. Do fatalism, superstition, and religious and cultural beliefs work as obstacles to road safety interventions in Pakistan? To address these questions, a qualitative research methodology was developed. The research focused on gathering data through individual in-depth interviewing using a semi-structured interview format. A sample of 30 participants was interviewed in Pakistan in the cities of Lahore, Rawalpindi and Islamabad. The participants included policy makers (with responsibility for traffic law), experienced police officers, religious orators, professional drivers (truck, bus and taxi) and general drivers selected through a combination of purposive, criterion and snowball sampling. The transcripts were translated from Urdu and analysed using a thematic analysis approach guided by the conceptual framework. The findings were divided into four areas: attribution of crash causation to fatalism; attribution of road crashes to beliefs about superstition and malicious acts; beliefs about road crash causation linked to popular concepts of religion; and implications for behaviour, safety and enforcement. Fatalism was almost universally evident, and expressed in a number of ways. Fate was used to rationalise fatal crashes using the argument that the people killed were destined to die that day, one way or another. Related to this was the sense of either not being fully in control of the vehicle, or not needing to take safety precautions, because crashes were predestined anyway. A variety of superstitious-based crash attributions and coping methods to deal with road crashes were also found, such as belief in the role of the evil eye in contributing to road crashes and the use of black magic by rivals or enemies as a crash cause. There were also beliefs related to popular conceptions of religion, such as the role of crashes as a test of life or a source of martyrdom. However, superstitions did not appear to be an alternative to religious beliefs. Fate appeared as the 'default attribution' for a crash when all other explanations failed to account for the incident. This pervasive belief was utilised to justify risky road use behaviour and to resist messages about preventive measures. There was a strong religious underpinning to the statement of fatalistic beliefs (this reflects popular conceptions of Islam rather than scholarly interpretations), but also an overlap with superstitious and other culturally and religious-based beliefs which have longer-standing roots in Pakistani culture. A particular issue which is explored in more detail is the way in which these beliefs and their interpretation within Pakistani society contributed to poor police reporting of crashes. The pervasive nature of fatalistic beliefs in Pakistan affects road user behaviour by supporting continued risk taking behaviour on the road, and by interfering with public health messages about behaviours which would reduce the risk of traffic crashes. The widespread influence of these beliefs on the ways that people respond to traffic crashes and the death of family members contribute to low crash reporting rates and to a system which appears difficult to change. Fate also appeared to be a major contributing factor to non-reporting of road crashes. There also appeared to be a relationship between police enforcement and (lack of) awareness of road rules. It also appears likely that beliefs can influence police work, especially in the case of road crash investigation and the development of strategies. It is anticipated that the findings could be used as a blueprint for the design of interventions aimed at influencing broad-spectrum health attitudes and practices among the communities where fatalism is prevalent. The findings have also identified aspects of beliefs that have complex social implications when designing and piloting driver intervention strategies. By understanding attitudes and behaviours related to fatalism, superstition and other related concepts, it should be possible to improve the education of general road users, such that they are less likely to attribute road crashes to chance, fate, or superstition. This study also underscores the understanding of this issue in high echelons of society (e.g., policy makers, senior police officers) as their role is vital in dispelling road users' misconceptions about the risks of road crashes. The promotion of an evidence or scientifically-based approach to road user behaviour and road safety is recommended, along with improved professional education for police and policy makers.
