The sources of inequity in the education system of Serbia and how to combat them

The concept of equal opportunity for all students is deeply embedded in the Serbian constitution and in education laws. On that level, there is no doubt that everyone is ensured an opportunity to receive quality education. Many measures in education policy have been created specifically to achieve this objective and make the system fair and inclusive. The Coleman Report was linked to a wave of optimism that certain educational measures would help in achieving these noble goals. This aim is a high priority in education in a democratic country, and due to its importance needs to be re-examined. Thus, the present research examines the equity of students in the Serbian education system, detecting areas on all educational levels that could be (or already are) systemic sources of inequity (e.g., criteria for preschool institution enrolment, the system of student awards, rationalisation of the school network, the concept of entrance exams to secondary school or university, etc.). A number of measures have already been taken in the system specifically to deal with inequity (e.g., the Preschool Preparatory Programme, dropout measures, inclusion, scholarships, etc.). The effects of these measures in particular are analysed in the present work. In addition to an analysis of the systemic sources of inequity in the Serbian education system, the article also makes recommendations for their overcoming. (DIPF/Orig.)

Shadows of militarism: an ethnography of trauma and resistance among soldiers and veterans in post-9/11 USA.

This thesis critically examines the military disciplining of trauma through a detailed ethnographic study of post-9/11 lower-enlisted soldiers and veterans in the U.S. who have links to a national movement of resistance to, and healing from, militarism. Drawing on 12 months of ethnographic fieldwork at two G.I. coffeehouses and with the post-9/11 veteran anti-militarism movement in U.S., it analyses the journey of joining the military, becoming a soldier, leaving the military and veteran identities. It explores militarism and military power as a cultural process which reproduces and conceals itself within normative conceptions of the everyday, and military trauma as a site of contested power and resistance. In doing so, this research addresses an urgent need to critically engage with military trauma as a means to challenge normalised discourses of militarism. This research reveals a disjuncture between the imagined and lived reality of military identities in the post-9/11 era. It explores the politics of recognition of veterans’ public and private lives, their contested identities, and their constrained relationship to the state. It argues that veterans are silenced and their identities reduced to symbolic tools in a public military imaginary which constructs military trauma into politically manageable categories, while disciplining and silencing the nation from critically examining war and militarism. In this way, this thesis argues that veterans serve a vital function in U.S. society by absorbing and containing the violence of the state, which then becomes unspeakable, unhearable, and inescapable. This thesis shows how a small number of soldiers and veterans are pushing back against this narrative. In sum, this thesis seeks to challenge the disciplinary effects of militarism upon trauma and support veteran voices to speak their own truths.

Contribution of plant-derived phenolic compounds to combat Candida species biofilms

Opportunistic fungal infections, namely involving Candida species, constitute a hot topic for scientific researchers. The present wor1( aims to access antifungal potential of plant-derived phenolic extrac:ls against planktonic cells and biofilms of Candida species. Eucalyptvs globulus Labill. (blue gum), Glycyrrhiza glabra L. (licorice), Juglans regia L. (walnut) and Salvia officina/is L. (sage) evidenced to be the most effective Candida growth inhibitors, using disc diffusion assay. Minmal inhibitory (MIC) and minimal fungicidal (MFC) concentrations, and chemical composition of extracts by using HPLC-DAO-ESVMS were also determined. Blue gum and walnut mainly exerted fungistatic potential, while sage exerted an interesting anti-Candida potential. However, the most prominent candidacidal potential was observed to licorice extract, being achieved the lowest MIC and MFC values. The candidacidal potential of these phenolic extracts was mainly attributed to their high abundance in flavonoids, mainly flavones: luteolin (sage) and apigen~ derivatives (licorice), and flavanones: liQuiritin derivatives (licorice). In order to deepen the knowledge on the most effective extract. its abiity to inhibit biofilm formation was evaluated. Overall, a double concentration of MFC value was necessary to achieve similar results in biofims. Row cytometry assays were also carried out, and the obtained results revealed that primary lesion of cellular membrane appear to be most relevant mode of action. Thus, plant derived phenolic compounds evidence a promising potential to combat Candida species biofilms, both individually or combined with conventional therapy.

Quality Physical Activity Participation for Military Veterans with a Physical Disability

Minimal research has explored what comprises a quality physical activity (PA) participation experience, particularly among military Veterans with a physical disability for whom evidence of the benefits of PA is growing. To address this research gap, this dissertation examines quality PA participation among military Veterans with a physical disability. Manuscript 1 explores the views of Veterans with a physical disability regarding what elements constitute a quality PA experience, and how these elements may be fostered. Eighteen Veterans with various physical disabilities and PA experiences participated in interviews. Four quality elements were identified via thematic analysis: group cohesion, challenge, having a role, and independence and choice. A further three factors (the physical and social environments, and program structure) were identified as precursors for a quality experience. Manuscript 2 explores how PA programs for Veterans with a physical disability are delivered, and how these delivery strategies link conceptually to quality participation. Interviews were conducted with program staff from three PA programs for Veterans, and program documentation collected, to develop an understanding of program delivery strategies. Four strategies with potential links to quality participation were identified through thematic analysis: foster social connections, challenge participants, tailor programs and outcomes to match participant needs, and include knowledgeable coaches and instructors. Manuscript 3 evaluates the participation of Veterans with functional impairments in PA events, and examines the relationships among quality precursors, quality elements, and participation outcomes. Results indicate that program participation did not promote long-term increases in PA indicators. However, an indicator of the quality element belongingness mediated the relationship at particular time-points between coach interpersonal skills and three participation outcomes: family integration, PA intentions, and PA planning. These findings suggest that a quality participation experience created by coaches may positively impact the transition to civilian life, and promote efforts to engage in ongoing PA. Overall, this dissertation contributes towards a greater depth in understanding of the experiences of Veterans with a physical disability in PA programs. The findings begin to provide a foundation for researchers and practitioners aiming to create, deliver, and promote quality PA interventions and programming for Veterans with a physical disability.

Experience modulates the psychophysiological response of airborne warfighters during a tactical combat parachute jump

We aimed to analyse the effect of experience level in the psychophysiological response and specific fine motor skills of novel and expert parachute warfighters during a tactical combat parachute jump. We analysed blood oxygen saturation, heart rate, salivary cortisol, blood glucose, lactate and creatinkinase, leg strength, isometric hand-grip strength, cortical arousal, specific fine motor skills and cognitive anxiety, somatic anxiety and self-confident before and after a tactical combat parachute jump in 40 warfighters divided in two group, novel (n = 17) and expert group (n = 23). Novels presented a higher heart rate, lactate, cognitive anxiety, somatic anxiety and a lower self-confident than experts during the jump. We concluded that experience level has a direct effect on the psychophysiological response since novel paratroopers presented a higher psychophysiological response than compared to the expert ones, however this result neither affected the specific fine motor skills nor the muscle structure after a tactical combat parachute jump.

New prophylactic and therapeutic treatments to combat pathogenic Enterohaemorrhagic Escherichia coli

Bacterial diarrhoeal diseases have significant influence on global human health, and are a leading cause of preventable death in the developing world. Enterohaemorrhagic Escherichia coli (EHEC), pathogenic strains of E. coli that carry potent toxins, have been associated with a high number of large-scale outbreaks caused by contaminated food and water sources. This pathotype produces diarrhoea and haemorrhagic colitis in infected humans, and in some patients leads to the development of haemolytic uremic syndrome (HUS), which can result in mortality and chronic kidney disease. A major obstacle to the treatment of EHEC infections is the increased risk of HUS development that is associated with antibiotic treatment, and rehydration and renal support are often the only options available. New treatments designed to prevent or clear E. coli infections and reduce symptoms of illness would therefore have large public health and economic impacts. The three main aims of this thesis were: to explore mouse models for pre-clinical evaluation in vivo of small compounds that inhibit a major EHEC colonisation factor, to assess the production and role of two proteins considered promising candidates for a broad-spectrum vaccine against pathogenic E. coli, and to investigate a novel compound that has recently been identified as a potential inhibitor of EHEC toxin production. As EHEC cannot be safely tested in humans due to the risk of HUS development, appropriate small animal models are required for in vivo testing of new drugs. A number of different mouse models have been developed to replicate different features of EHEC pathogenesis, several of which we investigated with a focus on colonisation mediated by the Type III Secretion System (T3SS), a needle-like structure that translocates bacterial proteins into host cells, resulting in a tight, intimate attachment between pathogen and host, aiding colonisation of the gastrointestinal tract. As E. coli models were found not to depend significantly on the T3SS for colonisation, the Citrobacter rodentium model, a natural mouse pathogen closely related to E. coli, was deemed the most suitable mouse model currently available for in vivo testing of T3SS-targeting compounds. Two bacterial proteins, EaeH (an outer membrane adhesin) and YghJ (a putative secreted lipoprotein), highly conserved surface-associated proteins recently identified as III protective antigens against E. coli infection of mice, were explored in order to determine their suitability as candidates for a human vaccine against pathogenic E. coli. We focused on the expression and function of these proteins in the EHEC O157:H7 EDL933 strain and the adherent-invasive E. coli (AIEC) LF82 strain. Although expression of EaeH by other E. coli pathotypes has recently been shown to be upregulated upon contact with host intestinal cells, no evidence of this upregulation could be demonstrated in our strains. Additionally, while YghJ was produced by the AIEC strain, it was not secreted by bacteria under conditions that other YghJ-expressing E. coli pathotypes do, despite the AIEC strain carrying all the genes required to encode the secretion system it is associated with. While our findings indicate that a vaccine that raises antibodies against EaeH and YghJ may have limited effect on the EHEC and AIEC strains we used, recent studies into these proteins in different E. coli pathogens have suggested they are still excellent candidates for a broadly effective vaccine against E. coli. Finally, we characterised a small lead compound, identified by high-throughput screening as a possible inhibitor of Shiga toxin expression. Shiga toxin production causes both the symptoms of illness and development of HUS, and thus reduction of toxin production, release, or binding to host receptors could therefore be an effective way to treat infections and decrease the risk of HUS. Inhibition of Shiga toxin production by this compound was confirmed, and was shown to be caused by an inhibitory effect on activation of the bacterial SOS response rather than on the Shiga toxin genes themselves. The bacterial target of this compound was identified as RecA, a major regulator of the SOS response, and we hypothesise that the compound binds covalently to its target, preventing oligomerisation of RecA into an activated filament. Altogether, the results presented here provide an improved understanding of these different approaches to combating EHEC infection, which will aid the development of safe and effective vaccines and anti-virulence treatments against EHEC.

Rótulos dos alimentos: como as pessoas entendem a informação nutricional?

A fim de combater o aumento dos casos de excesso de peso, o Ministério da Saúde definiu a rotulagem nutricional obrigatória para auxiliar o consumidor na compra dos alimentos. O objetivo do estudo foi verificar a percepção de consumidores com relação às informações contidas nos rótulos de alimentos. Foi desenvolvido um questionário sobre rotulagem de alimentos, que foi respondido por 29 indivíduos e analisados a partir do método do Discurso do Sujeito Coletivo. 59 por cento dos entrevistados leem as informações nutricionais contidas no rótulo. Observou-se modificação na compra e no consumo do alimento, principalmente com base na informação do valor calórico. Quanto ao entendimento do conceito de Valores Diários, percebe-se que a informação não é bem compreendida pelos consumidores. É importante uma ação educativa para a massificação da leitura e entendimento das informações nutricionais, a fim de promover melhores escolhas e dar subsídios aos indivíduos para que tenham autonomia na escolha de alimentos

Fatores associados à recuperação nutricional de crianças em programa de suplementação alimentar

OBJETIVOS: Identificar os fatores associados à recuperação nutricional de crianças inscritas no Programa de Incentivo ao Combate às Carências Nutricionais (ICCN) no Município de Mogi das Cruzes. MÉTODOS: Foi realizado um ensaio institucional não controlado com 570 crianças inscritas no ICCN, que foram seguidas de julho de 1999 a julho de 2001. O estado nutricional foi avaliado segundo índice altura/idade, sendo consideradas eutróficas as crianças com escore z > - 1; de risco as que apresentaram z > - 2 e < - 1; desnutridas moderadas aquelas com z < - 2 e > - 3; e desnutridas graves as que apresentavam z < - 3. O impacto do ICCN foi analisado através de modelo multivariado com o uso de equações de estimação (GEE - Generalized Estimating Equations), sendo considerado significativo p<0,05. RESULTADOS/CONCLUSÃO: Ao final do seguimento, houve a melhora nutricional das crianças, com um gradiente, sendo maior a recuperação quanto maior a deficiência nutricional inicial. Observaram-se ganhos em altura de 1,12, 0,82, 0,57 e 0,45 desvios-padrão para as desnutridas graves, moderadas, em risco nutricional e eutróficas, respectivamente. Os fatores associados à evolução nutricional das crianças desnutridas foram a idade de 12 a 24 meses ao ingressar no ICCN, o peso ao nascer igual ou superior a 3 kg e o aleitamento materno. Os fatores associados negativamente à evolução nutricional neste grupo foram idade da mãe entre 20 a 40 anos e a ausência de trabalho remunerado materno. Para as crianças em risco, a renda familiar também se mostrou associada à melhor evolução nutricional. A experiência do ICCN em Mogi das Cruzes sugere que os programas de suplementação alimentar têm papel relevante na recuperação nutricional de desnutridos

Energy system contributions to the special judo fitness test

Purpose: This study investigated the energy system contributions of judo athletes to the Special Judo Fitness Test (SJFT). Methods: Fourteen male judo athletes performed the SJFT, which comprised three periods of judo activity (A = 15 s, B and C = 30 s) interspersed with 10 s rest intervals. During this test, one athlete threw two others positioned 6 m from each other using the ippon-seoi-nage technique. The fractions of the aerobic, anaerobic alactic and anaerobic lactic systems were calculated based on oxygen uptake, the fast component of excess postexercise oxygen uptake, and changes in net blood lactate, respectively. The contribution of the three energy systems was compared using a repeated measures analysis of variance and Bonferroni's multiple comparisons test. Compound symmetry, or sphericity, was determined by Mauchly's test. A level of significance of 5% (P < .05) was adopted in all analyses. Results: The alactic energy system presented a higher (F = 20.9; P < .001; power observed = 1.0) contribution (86.8 +/- 23.6 kJ; 42.3 +/- 5.9%) during the test when compared with both aerobic (57.1 +/- 11.3 kJ; 28.2 +/- 2.9%) and lactic (58.9 +/- 12.1 kJ; 29.5 +/- 6.2%) energy systems (P < .001 for both comparisons). Conclusions: The higher alactic contribution seems to be a consequence of the high-intensity efforts performed during the test, and its intermittent nature. Thus, when using the SJFT, coaches are evaluating mainly their athletes' anaerobic alactic system, which can be considered to be the most predominant system contributing to the actions (techniques) performed in the match.
