Effect of subcooling and superheating on performance of a cascade refrigeration system with considering thermo- economic analysis and multi-objective optimization
Authors: Keshtkar Mohammad Mehdi
Published: July 2016

In present work, effect of degrees of subcooling and superheating based on thermoeconomic optimization is investigated in two stage-cascade refrigeration system (TS-CRS). At the first step, by using R717 and R744 as refrigerants, a thermoeconomic analysis is applied to TS-CRS. Based on results of the first section and using the genetic algorithm (GA) optimizer implemented in MATLAB, the optimum operative conditions of a specific TS-CRS is determined. Finally, based on the Pareto frontier obtained from the GA optimization, a decision-making strategy is then used to determine a final solution by TOPSIS method. Two single-objective optimization strategies (SOS), i.e. exergetic optimization and cost optimization, are applied on TS-CRS. The aim of the first strategy is to maximize the exergetic efficiency and the aim of the second strategy is minimizing the total annual cost of the system. The case study results show that, compared to the base design, the use of SOS for maximizing of exergetic efficiency can be increases the exergetic efficiency 94.5%. In addition, the use of the second SOS can decrease the total system cost by 11%. Using MOS compared to base design, exergetic efficiency and the total system cost can be increase by 99.1% and 28.6% respectively.

Inúmeras doenças que afetam a cultura do feijão são transmitidas por sementes para tal, são importantes estudos com sementes infectadas que produzam plântulas viáveis. Dessa forma, o objetivo do trabalho foi testar diferentes métodos de inoculação de Fusarium oxysporum em sementes de feijão e verificar seu efeito no desenvolvimento das plântulas. Utilizaram-se sementes da cv. BRS Expedito, as quais foram inoculadas pelos métodos de suspensão de esporos, de contato com restrição hídrica e inoculação do substrato com discos de BDA contendo micélio do fungo. O delineamento experimental foi inteiramente casualizado com oito repetições. Foram feitas avaliações de emergência, comprimento e massa seca de parte aérea e incidência de sintomas da doença em caule e folha. A inoculação do patógeno Fusarium oxysporum em sementes de feijão influencia negativamente o desenvolvimento das plântulas. O método de suspensão de esporos produz sintomas da doença com o menor comprometimento do desenvolvimento das plântulas.

Published: July 2016

This study tested the hypothesis that elevated plasma adrenaline or metabolic stress enhances exercise‐induced PGC‐1α mRNA and intracellular signaling in human muscle. Trained (VO2‐max: 53.8 ± 1.8 mL min−1 kg−1) male subjects completed four different exercise protocols (work load of the legs was matched): C – cycling at 171 ± 6 W for 60 min (control); A – cycling at 171 ± 6 W for 60 min, with addition of intermittent arm exercise (98 ± 4 W). DS – cycling at 171 ± 6 W interspersed by 30 sec sprints (513 ± 19 W) every 10 min (distributed sprints); and CS – cycling at 171 ± 6 W for 40 min followed by 20 min of six 30 sec sprints (clustered sprints). Sprints were followed by 3:24 min:sec at 111 ± 4 W. A biopsy was obtained from m. vastus lateralis at rest and immediately, and 2 and 5 h after exercise. Muscle PGC‐1α mRNA content was elevated (P < 0.05) three‐ to sixfold 2 h after exercise relative to rest in C, A, and DS, with no differences between protocols. AMPK and p38 phosphorylation was higher (P < 0.05) immediately after exercise than at rest in all protocols, and 1.3‐ to 2‐fold higher (P < 0.05) in CS than in the other protocols. CREB phosphorylation was higher (P < 0.05) 2 and 5 h after exercise than at rest in all protocols, and higher (P < 0.05) in DS than CS 2 h after exercise. This suggests that neither plasma adrenaline nor muscle metabolic stress determines the magnitude of PGC‐1α mRNA response in human muscle. Furthermore, higher exercise‐induced changes in AMPK, p38, and CREB phosphorylation are not associated with differences in the PGC‐1α mRNA response.

Non-Hodgkin lymphoma (NHL) is a serious disease, with a high proportion of mortality. Molecular genetic abnormalities are very common in NHL, but specific characterization in accordance to molecular genetics for lymphoma subtypes is not yet completed. This article summarizes the relationship between B- and T-NHL and molecular genetics. We focus on NHL subtypes and emphasize its features to figure out what is exposed about NHL genetics. The basis of this method is collection of biological specimens for genomic and genetic analyses. This summary may help to prompt prediction of outcomes and guide therapy in the future.

Emergency Information Forms for Children With Medical Complexity: A Simulation Study
Authors: Abraham George , Fehr James , Ahmad Fahd , Jeffe Donna B. , Copper Tara , Yu Feliciano , White Andrew J. , Auerbach Marc , Schnadower David
Published: July 2016

BACKGROUND:

Emergency information forms (EIFs) have been proposed to provide critical information for optimal care of children with medical complexity (CMC) during emergencies; however, their impact has not been studied. The objective of this study was to measure the impact and utility of EIFs in simulated scenarios of CMC during medical emergencies.

METHODS:

Twenty-four providers (12 junior, 12 experienced) performed 4 simulations of CMC, where access to an EIF was block randomized by group. Scenario-specific critical action checklists and consequential pathways were developed by content experts in simulation and pediatric subspecialists. Scenarios ended when all critical actions were completed or after 10 minutes, whichever came first. Two reviewers independently evaluated the video-recorded performances and calculated scenario-specific critical action scores. Performance in scenarios with and without an EIF was compared with Pearson’s χ2 and Mann–Whitney U tests. Interrater reliability was assessed with intraclass correlation. Each provider rated the utility of EIFs via exit questionnaires.

RESULTS:

The median critical action score in scenarios with EIFs was 84.2% (95% confidence interval [CI], 71.7%–94.1%) versus 12.5% (95% CI, 10.5%–35.3%) in scenarios without an EIF (P < .001); time to completion of scenarios was shorter (6.9 minutes [interquartile range 5.8–10 minutes] vs 10 minutes), and complication rates were lower (30% [95% CI, 17.4%–46.3%] vs 100% [95% CI, 92.2%–100%]) with EIFs, independent of provider experience. Interrater reliability was excellent (intraclass correlation = 0.979). All providers strongly agreed that EIFs can improve clinical outcomes for CMC.

CONCLUSIONS:

Using simulated scenarios of CMC, providers’ performance was superior with an EIF. Clinicians evaluated the utility of EIFs very highly.
Rheinzaberner Sigillaten in Pannonien
Authors: Gabler Dénes
Published: July 2016

The sigillata of Rheinzabern are overrepresented among ceramic types in Pannonia at almost every archeological site. Until today, from the excavated 266 sites, we know more than 15 thousand published Rheineabern sigillata. At certain cases, this strikingly high ratio is a result caused by the creation of the given camps or settlements after 180 AD. At settlements that were supposedly abandoned already at the beginning of the 3rd century, the number of such ceramics is lower. The legionary fortress that provided most of the known Rheine goods is Vindobona, while the highest number of material concerning canabae was published from Aquincum. Among the urban comunities, the quantity provided by the municipium of Brigetio holds the first place, while the utmost number of Rheine ceramics among the villas was published from Baláca. At native settlements the quantity of imported samian is relatively low, as their inhabitants lacked the financial opportunities and also the needs for imported goods. At the sanctuary areas, almost three quarters of the material of Pfaffenberg in Carnuntum consists of sigillata of Rheinzabern, while in the Isis sanctuary in Savaria, this ratio is only 7,2%. This type of sigillata is relatively rarely found in graves — we have 50 occurrences so far. Dishes intended for everyday usage of dwellers of towns and villas were also sigillata in many cases, while at settlements with native traditions they preferred bowls with reliefs. Sigillata of Rheinzabern emerged in Pannonia already in the Antonine age of, but at this time yet they were underrepresented in the presence of the sigillata of Lezoux. The greatest amount of Rheinzabern was transported into the province in the middle production section of the manufactory, i.e., between 180 and 230, in the age of the Severan conjuncture. Material dated to the middle third of the 3rd century in Pannonia is insignificant (2%), which can be attributed to the stagnation of trade relations, and to the inner and outer political situation of the Empire.

Published: July 2016

Resumo: O objetivo deste estudo foi o de descrever, com base no relacionamento entre os sistemas de informação SINAN (Sistema de Informação de Agravos de Notificação) e SIM (Sistema de Informações sobre Mortalidade), o perfil epidemiológico dos casos notificados de influenza por novo subtipo viral que evoluíram para óbito, durante a pandemia da doença. Foram utilizados dados secundários de ambos os sistemas referentes aos anos de 2009 e 2010. O relacionamento identificou 5.973 óbitos de casos notificados como influenza pandêmica. Destes, 2.170 (36,33%) haviam sido classificados no SINAN como confirmados para a enfermidade; 215 (3,6%), como infecção por outro agente infeccioso; e 3.340 (55,92%), como descartados. Após o relacionamento, alguns casos, que, no SINAN, foram encerrados com evolução para óbito por influenza (n = 658) ou óbito por outras causas (n = 847), não foram encontrados no SIM. O relacionamento entre os bancos de dados pode aprimorar o sistema de vigilância e o dimensionamento da morbimortalidade. Recomendamos o fortalecimento da vigilância da influenza no país com o uso do relacionamento entre os sistemas de informação do Ministério da Saúde.

ABSTRACT: In order to evaluate the efficiency of phytase in diets with low and high phytate phosphorus (PP) 0content, as a consequence of wheat bran inclusion, on the relative weight of organs, intestinal morphometry and performance, three hundred and eighty-four male Cobb500 broilers were housed in metabolic cages. Animals were assigned into four treatments in a 2x2 factorial scheme in a randomized block design with eight replicates of 12 birds each. From 11 days of age birds received experimental diets, which consisted of: Diet low in PP; Diet low in PP with phytase (500FTU kg-1); Diet with a high PP and Diet with a high PP with phytase (500FTU kg-1). At 22 and 32 days of age two birds were slaughtered in order to collect gizzard, heart, liver, cecum, cloacal bursa, and at 32 days, a portion of the duodenum, jejunum and ileum was collected for morphometric evaluation. From 22 to 32 days of age average feed intake, average weight gain, average body weight and feed conversion ratio were also evaluated. Data were subjected to analysis of variance, fixed effects of diet and phytase and interaction between factors as well as the random block effects were tested. There was no significant interaction for the variables studied, concluding that phytase in diets with low or high phytate phosphorus content did not change the relative weight of organs, intestinal morphometrics and performance; only isolated effects were observed.

Published: July 2016

ABSTRACT: The essential oil plants contents can be affected by several factors. For example, in certain plants, collection time has been observed to affect the content and chemical composition of the essential oil obtained from the plant. The objective of this study was to evaluate the effect of collection time on the content and chemical composition of the essential oil from guava ( Psidium guajava L.) leaves. Leaves were collected at different times of the day and the content and chemical composition of their essential oil was determined. Collection time did not qualitatively affect the chemical composition of the essential oil. However, concentration of certain substances in the oil, such as α-humulene and trans-caryophyllene, did significantly vary at different collection times. The main constituents of the essential oil of Psidium guajava are limonene (2.2-4.4%), trans-caryophyllene (18.1-17.1%), α-humulene (26.3-20.4%), aromadendrene (7.6-12.2%), α-selinene (7.3-11.3%), caryophyllene oxide (3.7-3.3%), humulene epoxide II (4.1-1.9%), and selin-11-en-4α-ol (7.2-11.1%). Leaves collected at 7:00 AM had higher essential oil production, with a content of 0.38% (d.b.), whereas leaves collected at 7:00 PM had lower essential oil production, 0.24% (d.b.). Chemical analysis showed that sesquiterpene compounds represented the highest concentration (62.0%), and monoterpenoids and monoterpenes represented the lowest concentrations (1.1 and 2.2%, respectively). Chemical classes that underwent major changes with respect to collection time were monoterpenes, sesquiterpenes, and sesquiterpenoids (2.2-4.4%, 63.8-61.7%, and 15.9-13.2%, respectively).

Resumo: Neste artigo, tomando como base o fato de a educação ser um fenômeno complexo e diverso, refletimos sobre o campo dos direitos humanos e dos direitos humanos linguísticos em relação à educação de surdos. Observamos certas convergências e divergências decorrentes do encontro dos direitos, das políticas e das línguas na proposição e construção de um processo educacional que reconheça e valorize a singularidade linguística e cultural de seu público. E, também, assumimos uma visão crítica em relação às perspectivas maniqueístas que têm gerado ilusões no campo da educação de surdos, as quais têm invisibilizado sua complexidade, generalizado suas particularidades e reduzido sua amplitude. Vimos a centralidade da questão linguística para os surdos, já que todos os direitos humanos estão, sem dúvidas, atrelados à língua e, portanto, os direitos humanos linguísticos constituem-se como basilares ao gozo dos direitos civis, sociais, políticos, econômicos e culturais. Enfim, a educação de surdos existe em meio às diferenças que a caracterizam, às línguas que a especificam e às convergências e divergências que a (trans)formam.

RESUMO Objetivo apresentar categorias que expliquem o funcionamento de linguagem de um bebê com sua mãe a partir do conceito de sistema semiótico benvenisteano e verificar se tais categorias podem ser descritas numericamente. Método Quatro díades foram acompanhadas em três etapas. O primeiro estudo consistiu na análise qualitativa das filmagens transcritas, realizadas em cada uma das etapas. Pretendeu-se identificar os princípios enunciativos atrelados à relação do sistema semiótico corporal do bebê à linguagem materna, a saber, os princípios da interpretância e homologia. Outro estudo foi realizado por meio da análise numérica descritiva das categorias enunciativas identificadas e pela escala de comportamentos mãe-bebê, a partir da aplicação do Software ELAN (EUDICO Linguistic Anotador). Resultados Percebeu-se mutualidade mãe-bebê na maior parte das cenas analisadas. Identificaram-se, na homologia e na interpretância, categorias enunciativas produtivas que demonstram a relação demanda do bebê com a interpretação materna. Também foi possível utilizá-las para descrever numericamente as interações mãe-bebê. Além disso, outras categorias emergiram havendo mais subtipos de produções maternas que não estão diretamente relacionadas à demanda do bebê, demonstrando que este está exposto à linguagem de características heterogêneas. Conclusão O conceito de sistema semiótico permitiu propor categorias de funcionamento de linguagem identificáveis na relação mãe-bebê. Tais categorias puderam ser descritas numericamente.

Published: July 2016

ABSTRACT Background: The association between diabetes mellitus and cognitive dysfunction is becoming increasingly clear, rendering it necessary for physicians in charge of diabetic patients to have the means to assess cognitive performance. Simple tests that can be applied during routine consultations may be useful for monitoring cognitive function during the course of diabetes. Objective: The objective of the present study was to assess cognition in diabetes mellitus type II (DM-II) using simple tests that can be incorporated into routine medical practice. Methods: A cross-sectional study including healthy controls and DM-II patients was carried out between May and September 2011. Volunteers aged 60 years and over were assessed by means of figure recognition, verbal fluency and the 10×36 tests. Results: A group of 100 participants was divided into a subgroup of 50 DM-II patients and a subgroup of 50 healthy volunteers. No statistical difference regarding demographic characteristics was found between the two groups. Results on the 10×36 test showed significantly worse performance among DM-II patients (p<0.0001). Assessment of the DM-II subgroup in terms of disease duration showed statistically significant differences (p<0.001) on figure recognition and verbal fluency, with worse cognitive performance among individuals with longer disease duration, irrespective of gender or age. Conclusion: Figure recognition, verbal fluency and 10×36 tests are easy to apply and could be used in routine medical practice for the early detection of cognitive dysfunction among patients with DM-II.

ABSTRACT During normal aging there are some cognitive and behavioral changes similar to those observed in a transitional state or mild cognitive impairment (MCI) and early onset dementia, making it challenging for health care professionals to reach an accurate and reliable diagnosis. Objective: The current study examined the performance of two different groups of patients diagnosed with probable Alzheimer's disease (AD) on a neuropsychological test battery. Methods: Twenty-two AD patients from Brasília-DF (AD1) and thirty-four AD patients from Palmas-TO, northern Brazil (AD2), were selected and a short neuropsychological battery administered. To verify the reliability of these previous diagnoses of AD, both groups of patients were compared with a group of healthy controls. Results: AD patients showed cognitive deficit but scores were lower for the AD2 group compared with the AD1 group considering the cut-off point. Notably, patients from the AD1 group were older (p=0.004) and had less formal education (p<0.001) than those from the AD2 group. Comparing different cognitive domains between AD groups, post hoc analysis showed that the AD1 group was characterized by deficits in episodic memory retrieval (p<0.001), semantic memory (p<0.001) and verbal fluency (p<0.001). In contrast, the AD2 group showed lower scores in attention (p=0.007), executive functioning (p<0.001) and working memory (p<0.001). Conclusion: This pattern suggests that the Palma group of patients had a neuropsychological profile that was inconsistent with AD. Although the results of this study have important clinical implications, the effects of age, education, and gender on cognitive performance should be explored further.
Relationship between cortical microinfarcts and cognitive impairment in Alzheimer's disease
Authors: Damasceno Benito P.
Published: July 2016

ABSTRACT Cerebrovascular disease and AD pathology co-exist in most dementia cases, and microinfarcts (MIs), particularly if cortical and multiple, play an additive and independent role in AD cognitive impairment. The main cause of cortical MIs is chronic cerebral hypoperfusion but occlusive vascular diseases, embolism and blood-brain barrier disruptions, isolated or combined, may also play a role. The precise mechanisms by which MIs cause cognitive impairment are not well known, but one plausible explanation is that they are widespread and accompanied by diffuse hypoperfusion, hypoxia, oxidative stress and inflammation, particularly in the watershed areas of the tertiary association cortex, and hence could damage cognition networks and explain many of AD's cognitive and behavioral disturbances. Therefore, it is crucial to control vascular risk factors and avoid uncontrolled use of the antihypertensives, neuroleptics and other sedative drugs frequently prescribed to AD patients.

The ribonuclease angiogenin is a component of the mammalian stress response that is secreted by renal epithelial cells on activation of the inositol–requiring enzyme 1α (IRE1α)–active spliced X–box binding protein 1 (sXBP1) axis and instrumental to the adaptation to AKI associated with endoplasmic reticulum stress. To determine whether the amount of angiogenin in urine of individuals with a kidney injury reflects the magnitude of the lesions and provides information on the risk of organ failure, we examined individuals referred for a kidney injury and determined the biochemical characteristics of urinary angiogenin and its diagnostic and prognostic values. Urinary angiogenin did not correlate with the urinary concentrations of high molecular weight proteins and correlated only weakly with low molecular weight proteins, suggestive of tubular production. In a cohort of 242 kidney transplant recipients with acute allograft dysfunction, higher urinary angiogenin concentrations at the time of the biopsy associated with worse renal function and higher proteinuria but did not correlate with histologic lesions as defined in the Banff classification. Kidney transplant recipients with urinary angiogenin amounts in the highest 50% had a risk of graft failure 3.59 times as high (95% confidence interval, 1.12 to 15.94) as that of patients with amounts in the lowest 50%. Finally, the amount of urinary angiogenin reflected the activity of the IRE1α-XBP1 axis in allografts. Our approach identified urinary angiogenin as a noninvasive indicator of the extent of tissue damage, independent of the histologic lesions, and a risk predictor of kidney allograft failure.
Die verband tussen werksbevrediging en die leierskapstyl van bestuurders: 'n Gevallestudie uit die banksektor

Die doel van die studie was om vas te stel op watter wyse die dominante leierskapstyl van opleidingsbestuurders die werksbevrediging van opleidingskonsultante wat volwasseneonderwys binne 'n bepaalde bankgroep in Suid-Afrika verskaf, beïnvloed. Bepaalde leierskapstyle (naamlik die demokratiese, outokratiese en laissez-faire-leierskapstyle) en werksbevredigingskomponente (naamlik ondersteuning, verhoudings en bemagtiging) is vir die doel geïdentifiseer. 'n Vraelys is ontwerp wat as kwantitatiewe navorsingsinstrument gedien het om inligting aangaande die biografiese besonderhede van respondente, hul bestuurder se leierskapstyl en respondente se persepsies van hul eie werksbevrediging in te samel. Een-en-negentig uit 137 respondente aan wie 'n e-pos gestuur is, het die vraelys voltooi. Die responskoers was dus 66.42%. Uit die analise van variansieresultate het dit geblyk dat leierskapstyl wél respondente se persepsie van al die gekose werksbevredigingskomponente statisties beduidend beïnvloed. In die geval van die belewing van ondersteuning is ouderdom verder ook as bydraende faktor tot werksbevrediging geïdentifiseer.
Politieke en regsfilosofiese perspektiewe op polito-kratiese kommunitarisme: 'n Diskoers met Danie Goosen en Koos Malan
Authors: Raath A
Published: July 2016

In hierdie artikel word aangevoer dat kommunitariese politieke en regsteorieë die afgelope twee dekades in Suid-Afrika op die voorgrond getree het. Twee vergestaltings daarvan kan onderskei word: Ubuntu-kommunitarisme en politokratiese kommunitarisme. Terwyl eersgenoemde beduidende ondersteuning in die Suid-Afrikaanse regsliteratuur verwerf het, het laasgenoemde benadering hoofsaaklik tot die Afrikaanse literatuur beperk gebly. Die fokus val op politokratiese kommunitarisme en politieke en regsfilosofiese implikasies daarvan. Politokratiese kommunitarisme berus op die Aristoteliese teleologie, 'n Skolastieke synsontologie en Hegel se dialektiese idealisme. As vertrekpunt neem politokratiese kommunitarisme die Aristoteliese stadstaat (polis). Die stadstaat ontwikkel evolusionêr as "tussen-gemeenskap" tot die Hegeliaanse konkreet-universele staat. Die eindproduk is die totalitêre organismiese staat. Kommunitariese politokrate slaag nie in hul projek om die statisme van die liberale individualisme te oorkom en 'n normatiewe alternatief vir statisme, politieke universalisme en die absolutistiese staat te stel nie. In hierdie artikel word tot die slotsom geraak dat die filosofiese hiate in die staats- en regsdenke van politokratiese kommunitarisme belangrike implikasies het: Die organismiese konsepsie wat spruit uit hierdie denke lei eerstens tot die postulering van 'n trans-individuele utopie gebaseer op 'n abstrakte gemeenskapslewe; tweedens is dié organismiese staat noodwendig 'n totalitäre (en absolutistiese) vorm van politieke gemeenskap; derdens, is die organismiese politieke gemeenskap 'n innerlik-teenstrydige en ongedifferensieerde vorm van politieke assosiasie en die organismiese staat word georden sonder erkenning van fundamentele regte.
Veranderlikes wat verband hou met swart hoërskool-leerders se prestasie in Afrikaans as 'n tweede taal
Authors: Bester G , Noke D
Published: July 2016

Navorsingsgegewens oor prestasie in 'n tweede taal kan nie sonder meer op Afrikaans by swart leerders van toepassing gemaak word nie, gesien in die lig daarvan dat swart leerders nie in hulle moedertaal onderrig word nie, maar in Engels wat alreeds hulle tweede taal is. 'n Verdere probleem is dat vorige ondersoeke nie beide kognitiewe en affektiewe veranderlikes betrek het nie. Die kwaliteit van onderrig of leerstyl van die leerders word ook nie gelyktydig saam met kognitiewe en affektiewe veranderlikes ondersoek nie. Dit is gevolglik moeilik om vas te stel watter van hierdie veranderlikes as die belangrikste beskou kan word ten einde die variansie in die prestasie van Afrikaans as 'n tweede taal te kan verklaar. 'n Empiriese ondersoek is uitgevoer waarby 174 swart hoërskoolleerders betrek is. Kognitiewe en affektiewe veranderlikes, asook leerders se leerstyle, is gemeet. Uit die empiriese ondersoek blyk dit dat selfkonsep, geheue, verbale begrip en motivering as die belangrikste veranderlikes beskou kan word wat met prestasie in Afrikaans as tweede taal verband hou. Leerstyl is nie as 'n belangrike faktor geïdentifiseer nie. Uit die resultate kan twee spesifieke aanbevelings gemaak word: Eerstens moet die belangrikheid van lees opnuut deur onderwysers beklemtoon word. Die aanbeveling word gemaak op grond daarvan dat verbale begrip as 'n belangrike kognitiewe veranderlike na vore gekom het. Verbale begrip hou verband met aspekte soos woordeskat-uitbreiding en sinskonstruksie wat in 'n groot mate deur leesaktiwiteite bevorder word (Echols, West, Stanovich & Zehr 1996:296-304). Tweedens moet onderwysers daarop bedag wees dat affektiewe faktore 'n belangrike rol in die klaskamer speel waar 'n tweede taal onderrig word.

“Otherness” as Threat: Social and Educational Exclusion of Roma People in Greece
Authors: Parthenis Christos , Fragoulis George
Published: July 2016

This paper focuses on aspects of the social and educational exclusion that Roma people face in the Greek context. It argues that diversity has been constructed as a threat for the security, the social cohesion, and the well-being of western societies. Drawing from two case studies of primary schools conducted in a highly deprived suburb of Athens, where most Roma live in harsh conditions, we argue that socially constructed dispositions regarding diversity and inadequate state policies are major obstacles for the improvement of educational opportunities and life chances of Roma people in Greece.
A comparison of WISC-R and WAIS-R (PL) scores of children and adolescents in a longitudinal study
Authors: Sochacka Krystyna
Published: July 2016

D. Wechsler’s tests were used to examine the same group of subjects within the intellectual norm (N = 31) twice over an interval of 13 years: the Wechsler Intelligence Scale for Children (WISC-R; the subjects’ mean age was 8 years) and the Wechsler Adult Intelligence Scale (WAIS-R; mean age – 21 years). Each measurement was carried out by the same person. Based on 62 protocols (answer sheets), intelligence quotients, scaled subtest scores, and factor scores obtained using WISC-R were compared both with the normalized version of WAIS-R (PL) (2004) and with the version of WAIS-R (PL) from before normalization (1996). Statistically significant differences were found between the results obtained using WISC-R and the normalized version of WAIS-R (PL). There is no such difference between WISC-R and the earlier version of WAIS-R (PL), from before normalization. Implications for clinical practice are discussed.
