Implementing an inclusion policy in a primaryschool:findings and recommendations from a case study approach

This article is based on a case study carried out in a small inner-city primary school in the English south midlands. The key determinant of the research was to examine the factors affecting the progress of children in the school, assess the school's response and to make recommendations that would enhance good practice and undertake responsibilities under the Race Relations Act (2000). The focal point was children for whom English is an additional language (EAL). This article considers the relevance of such a study in gathering the views of EAL and minority ethnic parents, carers and professionals and how far it could be utilized by any school as part of a regular check to determine how well it is providing for their children.

Polymer degradation and stability

This edition of Polymer Degradation and Stability is dedicated to papers which were presented in the session on ‘Chemical Modification’ at the Third International Conference on Modification Degradation and Stabilisation of Polymers (MoDeSt) held in Lyon in August 2004. This was the third meeting of the MoDeSt Society which was set up in the year 2000 under the chairmanship of Professor Franco LaMantia; the earlier meetings were held in Palermo (2000) and Budapest (2002). The overall goal of the MoDeSt Society is to promote the latest research carried out in University laboratories, in public organisations and in industry through publications, and organisation of biannual scientific conferences and workshops that act as forums for scientific developments and for promoting networking between academics and industrialists from across the field of polymer modification, degradation and stabilisation. In September 2004, Professor Norman Billingham was elected as Chairman of the Society. The conference was organised by Dr Alain Michel and Veronique Bounor-Legare of the University Claude Bernard, Lyon 1, attracting over 250 delegates with the ‘Chemical Modification’ Session alone enjoying 54 oral presentations and many more poster presentations. We are all very grateful to the organisers for running such a successful and enjoyable meeting. I wish to thank my co-editors, Professors Philippe Dubois and Domenico Acierno and Dr Alain Michel, for their cooperation in the editorial task of the papers published in this special issue. On behalf of the editors of this issue, I wish to express our appreciation to the Editor-in-Chief of Polymer Degradation and Stability, Professor Norman Billingham, for the support and help received during the preparation of this special issue.

Здравко Д. Славов - В тази статия се разглежда математически модел на икономика с фиксирани общи ресурси, както и краен брой агенти и блага. Обсъжда се ролята на някои предположения за отношенията на предпочитание на икономическите агенти, които влияят на характеристиките на оптимално разпределените дялове. Доказва се, че множеството на оптимално разпределените дялове е свиваемо и притежава свойството на неподвижната точка.

Airline Deregulation, Computerized Reservation Systems, and Travel Agents

With the beginning of airline deregulations in 1978, U.S. domestic operations were in for a period of turmoil, adjustment, vibrancy, entrepreneurship, and change. A great deal has been written about the effects of deregulation on airlines and their personnel, and on the public at large. Less attention has been paid to the effects on travel agents and on the seminal role of computerized reservations systems (CRSs) in the flowering of travel agencies. This article examines both of these phenomena.

Bacteria and tumours: causative agents or opportunistic inhabitants?

Associations between different bacteria and various tumours have been reported in patients for decades. Studies involving characterisation of bacteria within tumour tissues have traditionally been in the context of tumourigenesis as a result of bacterial presence within healthy tissues, and in general, dogma holds that such bacteria are causative agents of malignancy (directly or indirectly). While evidence suggests that this may be the case for certain tumour types and bacterial species, it is plausible that in many cases, clinical observations of bacteria within tumours arise from spontaneous infection of established tumours. Indeed, growth of bacteria specifically within tumours following deliberate systemic administration has been demonstrated for numerous bacterial species at preclinical and clinical levels. We present the available data on links between bacteria and tumours, and propose that besides the few instances in which pathogens are playing a pathogenic role in cancer, in many instances, the prevalent relationship between solid tumours and bacteria is opportunistic rather than causative, and discuss opportunities for exploiting tumour-specific bacterial growth for cancer treatment.

Synergy between histone deacetylase inhibitors and DNA- damaging agents is mediated by histone deacetylase 2 in colorectal cancer

Previous studies have associated the overexpression of histone deacetylase 2 (HDAC2) and the presence of TP53 mutations with the progression to advanced stage drug resistant colorectal cancer (CRC). However, the mechanistic link between HDAC2 expression and the TP53 mutational status has remained unexplored. Here, we investigated the function of HDAC2 in drug resistance by assessing the synergistic effects of DNA-targeted chemotherapeutic agents and HDAC inhibitors (HDACis) on two TP53-mutated colorectal adenocarcinoma CRC cell lines (SW480 and HT-29) and on the TP53-wild type carcinoma cell line (HCT116 p53+/+) and its TP53 deficient sub-line (HCT116 p53-/-). We showed that in the untreated SW480 and HT-29 cells the steady-state level of HDAC2 was low compared to a TP53-wild type carcinoma cell line (HCT116 p53+/+). Increased expression of HDAC2 correlated with drug resistance, and depletion by shRNA sensitised the multi-drug resistance cell line HT-29 to CRC chemotherapeutic drugs such as 5-fluorouracil (5-FU) and oxaliplatin (Oxa). Combined treatment with the HDACi suberoylanilide hydroxamic acid plus 5-FU or Oxa reduced the level of HDAC2 expression, modified chromatin structure and induced mitotic cell death in HT-29 cells. Non-invasive bioluminescence imaging revealed significant reductions in xenograft tumour growth with HDAC2 expression level reduced to <50% in treated animals. Elevated levels of histone acetylation on residues H3K9, H4K12 and H4K16 were also found to be associated with resistance to VPA/Dox or SAHA/Dox treatment. Our results suggest that HDAC2 expression rather than the p53 mutation status influences the outcome of combined treatment with a HDACi and DNA-damaging agents in CRC.

Strontium isotopes and sedimentology of a marine Triassic succession (upper Ladinian) of the westernmost Tethys, Spain

Chemical Stratigraphy, or the study of the variation of chemical elements within sedimentary sequences, has gradually become an experienced tool in the research and correlation of global geologic events. In this paper 87Sr/ 86Sr ratios of the Triassic marine carbonates (Muschelkalk facies) of southeast Iberian Ranges, Iberian Peninsula, are presented and the representative Sr-isotopic curve constructed for the upper Ladinian interval. The studied stratigraphic succession is 102 meters thick, continuous, and well preserved. Previous paleontological data from macro and micro, ammonites, bivalves, foraminifera, conodonts and palynological assemblages, suggest a Fassanian-Longobardian age (Late Ladinian). Although diagenetic minerals are present in small amounts, the elemental data content of bulk carbonate samples, especially Sr contents, show a major variation that probably reflects palaeoenvironmental changes. The 87Sr/86Sr ratios curve shows a rise from 0.707649 near the base of the section to 0.707741 and then declines rapidly to 0.707624, with a final values rise up to 0.70787 in the upper part. The data up to meter 80 in the studied succession is broadly concurrent with 87Sr/86Sr ratios of sequences of similar age and complements these data. Moreover, the sequence stratigraphic framework and its key surfaces, which are difficult to be recognised just based in the facies analysis, are characterised by combining variations of the Ca, Mg, Mn, Sr and CaCO3 contents

Terapia de aceptación y compromiso en un caso de tras¬torno mixto de ansiedad y depresión en una paciente con cáncer

This paper introduces the case of a woman with breast cancer who had developed a mixed depressive-anxiety disorder with avoidance behaviors. The patient presented depressive symptoms like listlessness, insomnia, weeping, food disorders and hopelessness though. Also, she exhibited physiological arousal and restlessness feelings. Additionally, the patient had an avoidance patron behavior in relation with all stimulus she believed could hurt her. Based on the Acceptance and Commitment Therapy (ACT) the intervention planted the following objectives: the patient will learn to accept her illness and the emotional distress that she was experiencing, also, the patient will recover the other areas of her life that she had abandoned. The treatment was developed in 14 sessions. The therapist used these techniques: creative hopelessness, disabling verbal functions, values clarification and loss of control over private events. In the results, it was observed a positive change in the behavior of the patient as well as a decrease in emotional distress that was his reason for initial consultation

Motivation and Vocabulary Breadth in CLIL and EFL Contexts. Different age, Same Time of Exposure

Numerous studies have found a positive connection between learners’ motivation towards foreign language and foreign language achievement. The present study examines the role of motivation in receptive vocabulary breadth (size) of two groups of Spanish learners of different ages, but all with 734 hours of instruction in English as a Foreign Language (EFL): a CLIL (Content and Language Integrated Learning) group in primary education and a non-CLIL (or EFL) group in secondary education. Most students in both groups were found to be highly motivated. The primary CLIL group slightly overcame the secondary non-CLIL group with respect to the mean general motivation but this is a non-significant difference. The secondary group surpass significantly the primary group in receptive vocabulary size. No relationship between the receptive vocabulary knowledge and general motivation is found in the primary CLIL group. On the other hand, a positive significant connection, although a very small one, is identified for the secondary non-CLIL group. We will discuss on the type of test, the age of students and the type of instruction as variables that could be influencing the results.

Receptive Vocabulary of CLIL and Non-CLIL Primary and Secondary School Learners

CLIL instruction has been reported to be beneficial for foreign language vocabulary learning since CLIL students show higher vocabulary profiles than students of their same age in traditional EFL contexts. However, to our knowledge, the receptive vocabulary knowledge of CLIL and non-CLIL learners at the end of primary and secondary education has not been examined yet. Hence, this study aims at comparing the receptive vocabulary size 79 CLIL primary learners with the receptive vocabulary knowledge of 331 non-CLIL learners at the end of primary and secondary school. Sex-based differences were also analysed. The 2k Vocabulary Levels Test (VLT) was used for the purposes of the study. Results revealed that learners’ receptive vocabulary sizes lie within the most frequent 1000 words, non-CLIL secondary school students throw better results than primary students but the differences between the secondary group and the CLIL group are not statistically significant. As for sex-based differences, we found no significant differences among the groups. These findings led us to believe that the CLIL approach offers a benefit for vocabulary acquisition since CLIL learners have been exposed to the foreign language for a shorter period of time and the results are quite similar to their non-CLIL secondary school partners.

The Effect of Water Consumption on Schoolchildren's Fine Motor Skills, Cognitive Function and Mood

Previous research has suggested that dehydration may have a negative effect on some aspects of mood, cognitive performance and motor skills (Benton, 2011). Furthermore, a large proportion of children arrive at school in a dehydrated state (Baron, Courbebaisse, Lepicard, & Friedlander, 2015). The present work investigated whether supplementing children with water may, as a consequence of reducing dehydration, improve their cognitive performance and motor skills. In studies 1, 2, 3 and 5, it was found that tasks that predominantly tested motor skills, were improved in children who had a drink, compared to those who did not. Furthermore, study 3 showed that this effect was moderated by hydration status. One theoretical explanation for the poorer performance of dehydrated children is that they may lack the neurological resources to sustain their effort and thus performance does not improve over time. In support of this, these studies showed that, when re-hydrated, performance on these tasks improves to the level of non-dehydrated children. Study 2 showed that the number of errors increased in a StopSignal task in children that had high self-rated levels of thirst, compared to low levels: and hydration status did not moderate this effect. A possible explanation for the increased number of errors in children with high self-rated thirst is that the thirst sensation diverts attention away from the task, causing task performance to deteriorate. In study 4, it was observed that there was a large variation in intra-individual and inter-individual hydration scores throughout the day, which was not related to volume drank or levels of thirst. Further studies should use imaging techniques to study brain activity during dehydration and rehydration, and during periods of high thirst, to help to further elucidate the mechanism underlying the negative effect of dehydration on motor performance, and the effect of self-rated thirst on attention.

The Voice of History and the Message of the National Curriculum: Recontextualising History to a Pedagogic Discourse for Upper Secondary VET

In the reform by the liberal-conservative government of Swedish upper secondary education in 2011, history was recognized as an important part of citizenship education and was introduced into the curriculum for vocational education and training (VET) tracks. Through the concepts of classification and framing, this article explores the process of constructing the history syllabus for VET. The data consist of archived material from the working group responsible for the history curriculum under the Swedish National Agency for Education. The analysis shows that there are competing discourses concerning the relative emphasis on competencies and skills and concerning the emphasis on contemporary and modern history. Although historians, history teachers and other agents are invited to respond to the content of the curriculum, the respondents have no influence on the knowledge structure of the curriculum, which is controlled by agents of the dominant educational ideology. From a critical perspective, this article suggests that the curriculum reflects the instrumental and neoconservative message of the reform through strong classification and framing and through the emphasis on general abilities and a contemporary history that has a more direct explanatory value to contemporary society.

Att möta det förflutna i de historiska källorna. Ett utforskande av lärande och meningsskapande genom två källtolkningsuppgifter i historia.

The article uses a form of content focused conversation analysis to explore processes of learning and attributing meaning when upper secondary students work with two primary source assignments in history. Empirical data was collected through audio recordings of students’ collaborative work on the assignments, which consisted in analysing two primary sources in small groups. The article addresses one primary research question: what is characteristic for the processes of learning and meaning-making when students work with two source analysis assignments? As a first step, the students’ learning processes, understood as a change in participation in the learning activity, are described. As a second step, the article describes how the students’ construct meaning when working with the primary sources. The main results are descriptions of the students’ learning, and meaning-making, processes. Based on the analysis of the students’ conversations it is suggested that the temporal aspect is discerned in a contrastive process between the present and the past in terms of values, ideas and societal conditions. In relation to the human aspect the students experienced a difficult balancing act in contrasting their own perspective with the historical actor’s perspective. However, a successful strategy was to take on the role of hypothetical historical agents. Finally, in relation to the contextual aspect once the students were involved in a process of inquiry and reasoning they managed to discern subtexts of the sources in relation to the historical context. It is suggested that certain aspects of school culture might inhibit the students’ learning of primary source analysis, as they occasionally strive to find the "right answers" rather than engaging in interpretative work. One interesting finding was the vital role of the students’ life-world perspective in creating meaning while working with the primary sources, and it is suggested that this perspective should be regarded in educational design.
