‘It’s good enough that our children are accepted’: Roma mothers’ views of children’s education post migration

The discrimination of Roma groups across Europe has been highlighted by several international organisations. For many, poverty, racism and their children’s systematic exclusion from education are ‘push’ factors when deciding to migrate. This study explores Roma mothers’ views of their children’s education post migration and their attitudes to education more broadly, by adopting an intersectional framework and examining issues of difference and belonging as experienced by Roma mothers and their children. While Roma mothers recognised the value of education for social mobility, they remained aware of the limited resources they could draw upon, in the absence of desirable economic and cultural capitals, and as a result of their ethnicity, social class, gender and ‘undesirable migrant’ status. There was a perceived hopelessness in relation to the chances that Roma children have to overcome their marginalisation through schooling, pointing to the need for dedicated policy interventions when working with Roma families.

Tert-butyl amine borane complex: An unusual application of a reducing agent on model molecules of cellulose based materials

The need to preserve cultural heritage on paper requires the setting up of methods and treatments that can be applied to original documents. The cellulose main degradation processes are hydrolysis and oxidation. Only the first one has been widely investigated. The Istituto Centrale per la Patologia del Libro (ICPL) focused its attention on oxidation phenomena and studied a particular class of reducing agents, namely the borane-amine complexes. During the investigation it was found that the borane tert-butylamine complex, besides being the most promising reducing agent, was also able to react with carboxylic functions. In the present study ¹H and ¹³C NMR, Pulsed field gradient NMR spectroscopy as well as Raman spectroscopy were used as analytical tools to disclose the mechanism of the interaction between the borane tert-butylamine complex and the carboxylic functions. Given the complexity of the paper/environment interactions and the subsequent degradation phenomena, we worked on simplified models based on small carbohydrate molecules in order to reproduce the behavior of degraded paper after reductive restoration. Modified D-glucose and D-cellobiose were used in this first step in order to set up the analytical methods before approaching more complex systems such as microcrystalline cellulose and paper. Our results give the experimental evidence that borane tert-butylamine complex is also able to neutralize acidic functions. This finding has important perspectives in paper restoration.     

Pacing during a cross-country mountain bike mass-participation event according to race performance,experience, age and sex

This study describes pacing strategies adopted in an 86-km mass-participation cross-country marathon mountain bike race (the ‘Birkebeinerrittet’). Absolute (km·h^?1) and relative speed (% average race speed) and speed coefficient of variation (%CV) in five race sections (15.1, 31.4, 52.3, 74.4 and 100% of total distance) were calculated for 8182 participants. Data were grouped and analysed according to race performance, age, sex and race experience. The highest average speed was observed in males (21.8?±?3.7?km/h), 16–24?yr olds (23.0?±?4.8?km/h) and those that had previously completed >4 Birkebeinerrittet races (22.5?±?3.4?km/h). Independent of these factors, the fastest performers exhibited faster speeds across all race sections, whilst their relative speed was higher in early and late climbing sections (Cohen's d?=?0.45–1.15) and slower in the final descending race section (d?=?0.64–0.98). Similar trends were observed in the quicker age, sex and race experience groups, who tended to have a higher average speed in earlier race sections and a lower average speed during the final race section compared to slower groups. In all comparisons, faster groups also had a lower %CV for speed than slower groups (fastest %CV?=?24.02%, slowest %CV?=?32.03%), indicating a lower variation in speed across the race. Pacing in a cross-country mountain bike marathon is related to performance, age, sex and race experience. Better performance appears to be associated with higher relative speed during climbing sections, resulting in a more consistent overall race speed.     

Catégories et fonctions dans l’appareil de l’état au temps des Barmécides: un sondage sur le glissement entre les rôles

This essay is part of a wider research project aiming to define the components of the élite in power during the first ?Abbāsid period. Our present purpose is to verify if, and to what extent, the sliding among different public roles must be related with the “arbitraire” of the caliph or rather if it would be reasonable to discern in it some automatisms, some unregulated, although already applied paths. For this purpose, we carried out a survey of the figures who had offices in the administration of the ?Abbāsid state during the second half of the 2nd/8th century, i.e. the Barmakids and those who evolved with them on the political scene. In the initial stage, we confined our survey to the figures appearing in the Kitāb al-wuzarā’ wa'l-kuttāb by al-Jahshiyārī (d. 331/942), that is, with al-?ūlī's one, the most ancient collection of akhbār devoted to the vizirs. We actually think that this work has a historical as well as a symbolic significance. In our opinion the fact of having been produced inside the official milieu of the 4th/10th century increases its value as a source for the social history of the first ?Abbāsid period. Facing the problem of the sliding among different public roles, we tried to fix some criteria for the statistical analysis of this phenomenon, as well as to deduce how this could be used for the study of the social components of the ?Abbāsid élite.     

pH controlled staining of CD4+ and CD19+ cells within functionalized microfluidic channel

Herein proposed is a simple system to realize hands-free labeling and simultaneous detection of two human cell lines within a microfluidic device. This system was realized by novel covalent immobilization of pH-responsive poly(methacrylic acid) microgels onto the inner glass surface of an assembled polydimethylsiloxane/glass microfluidic channel. Afterwards, selected thiophene labeled monoclonal antibodies, specific for recognition of CD4 antigens on T helper/inducer cells and CD19 antigens on B lymphocytes cell lines, were encapsulated in their active state by the immobilized microgels. When the lymphocytes suspension, containing the two target subpopulations, was flowed through the microchannel, the physiological pH of the cellular suspension induced the release of the labeled antibodies from the microgels and thus the selective cellular staining. The selective pH-triggered staining of the CD4- and CD19-positive cells was investigated in this preliminary experimental study by laser scanning confocal microscopy. This approach represents an interesting and versatile tool to realize cellular staining in a defined module of lab-on-a-chip devices for subsequent detection and counting.     

From departure to arrival: Re-engaging students who have withdrawn from university

Despite institutional strategies to prevent student withdrawal, attrition remains a concern across higher education sectors in the United States, the United Kingdom and Australia. In the case of Australian universities, attrition rates have remained consistently high since 2002. Some level of attrition is inevitable, but universities can influence the circumstances and the consequences of departure. This article draws on two research projects conducted within an Australian institution. The studies confirm that withdrawing students: often leave for personal reasons; are typically young and from under-represented backgrounds; generally remain positive about higher education; and are relatively likely to return to the sector in future. Despite our findings, institutional strategies around the point of departure remain variable and, contrary to their stated intentions, departing students are rarely seen as future students by the institutions from which they withdraw. Preventive strategies need to be combined with broader institutional policies designed to re-engage and re-recruit the cohort of departed students.     

Holistic or analytic rubrics? Grading information literacy instruction

Abstract

Studies about the assessment of information literacy instruction have reported the use of specific grading criteria, also known as rubrics, to evaluate students’ responses. Rubrics can be divided into two general categories: (1) holistic, where one score is assigned for evaluating the successful completion of a task; and (2) analytic, where a grade is subdivided into discrete components needed to complete the task and each component is given its own score for achievement. This article will investigate which scoring method—employing holistic versus analytic rubrics—is the most effective for evaluating students’ search strategies in terms of providing constructive feedback to students and informing the librarian’s future teaching practices.
