description: Background: Metabolic syndrome (MetS) is a cluster of interconnected risk factors, including obesity, hypertension, elevated blood sugar, and abnormal lipid profiles. Its increasing prevalence globally poses a significant public health concern. This study investigated the prevalence of hypertension and type 2 diabetes mellitus (T2DM) in patients with MetS, considering age and gender in a rural teaching hospital.

 

Methodology: Conducted at Igbinedion University Teaching Hospital, Edo State, the study involved 75 patients selected through simple random sampling using the 2009 Joint Interim Statement (JIS) criteria of the IDF/AHA/NHLBI. It utilised an observational, cross-sectional, and retrospective design, focusing on individuals aged 18 years and older who consented to participate. Data was analysed using IBM SPSS version 23, with p < 0.05 considered significant.

 

Results: The findings indicated that 60% of patients with MetS had hypertension, 17.3% had T2DM, and 22.7% were diagnosed with both conditions. Among hypertensive patients, 57.3% were female (P = 0.110). For T2DM, 25.3% of patients were female (P = 0.766). The prevalence of both T2DM (P = 0.106) and hypertension (P = 0.708) was higher in middle-aged patients compared to other age groups.

 

Conclusion: This study highlights the significant prevalence of hypertension and T2DM among patients with MetS in a rural teaching hospital, with notable variations across gender and age groups. While hypertension was more common in females, T2DM showed no significant gender disparity. Middle-aged individuals exhibited a higher prevalence of both conditions, underscoring the need for targeted screening and intervention strategies in this demographic.

description: Professionelles medienpädagogisches Handeln ist nie frei von Interessen – vor allem nicht, wenn es um die Gestaltung einer "Bildungsrevolution" und einen "radikalen" Wandel des Lernens geht. In der Rezension wird in den Mittelpunkt gerückt, dass die Gestaltung der digitalen Bildungsrevolution, die von Dräger und Müller-Eiselt vorgeschlagen wird, vor allem dem Mythos des Marktes als Ideologie huldigt und wenig zur Bildung des Menschen beiträgt.

description: Background: Malaria is a life-threatening parasitic infection associated with high morbidity and mortality in endemic regions. The World Health Organization (WHO) has approved two malaria vaccines for use in children and as countries begin the phased rollout of these vaccines, uncertainties around community awareness, attitudes, and willingness to accept the vaccines remain.
Methodology: This study used a multistage sampling to select 200 mostly female caregivers of children under the age of five years in Samaru, a semi-urban community in Kaduna State, North-western Nigeria. Data on knowledge, attitude, and willingness to accept the malaria vaccine was obtained using a structured questionnaire and analysed using IBM SPSS Statistics. Knowledge and attitude were scored and graded into good and poor categories. The data was presented using frequency tables and a chi-square test was used to check for associations between willingness to accept malaria vaccine and relevant variables. A P value < 0.05 was considered statistically significant.
Results: The majority of the respondents were females (65.5%) and married (93.0%), with a mean age of 33.1 (±9.3) years. Fifty-seven (28.5%) caregivers heard of the malaria vaccine mostly through healthcare workers and traditional media, while 39 (19.5%) showed good knowledge of the vaccine. A total of 194 (97.0%) had a good attitude towards the vaccine, 188 (94.0%) were willing to accept the vaccine, and 176 (88.0%) said they were willing to pay for it. Factors associated with vaccine acceptance included the caregiver being vaccinated as a child, having at least one child who is vaccinated, and having a good attitude toward the vaccine.
Conclusion: Despite low awareness, willingness to accept the malaria vaccine was high in the community. It is recommended that immediate steps be taken by relevant stakeholders to educate the public and begin the rollout of the vaccine to avoid the spread of rumours and misconceptions.

description: Background: Fraud in healthcare is an immense challenge that poses a direct threat to sustainable healthcare financing across low and high-income countries. Enrollee health insurance fraud is a relatively understudied form of fraud that thrives in settings characterized by weak and fragmented healthcare systems. This study examined the knowledge and perception of enrollee health insurance fraud among healthcare workers at a tertiary hospital in Kaduna State, North-western Nigeria.

 

Methodology: Using a stratified sampling technique, 232 healthcare workers were interviewed using a structured, self-administered questionnaire that was developed for the study. Data on knowledge and perception of enrollee fraud was obtained and analysed using IBM SPSS Statistics. The data was presented using frequency distribution tables, while figures were drawn using Microsoft Excel.

 

Results: The majority of the respondents were clinical staff, including medical doctors (29.7%), nurses (31.5%) and health assistants (14.2%). A total of170 (73.3%) respondents were aware of enrollee fraud and up to 113 (66.5%) encountered at least one case of enrollee fraud. The most common types of enrollee fraud identified by the respondents were impersonation (67.7%) and faking symptoms (57.1%). Respondents recognised adverse consequences of enrollee fraud, including depletion of resources (74.1%), blocking eligible patients from accessing care (73.6%), and exhaustion of healthcare workers (61.8%). A total of 111 (65.3%) agreed that enrollee fraud is common in the hospital and despite a high level of awareness, only 72 (42.3%) agreed that they are adequately informed about enrollee fraud.

 

Conclusion: There was a high level of awareness of enrollee fraud among the respondents with a good perception of its manifestations and implications on healthcare delivery. It is recommended that immediate steps be taken to educate healthcare workers and enhance their capacity to detect and deter enrollee fraud while investing in long-term strategic measures and technology-based solutions.

description: Seit den 1980er Jahren hat sich viel getan im Feld der wissenschaftlichen Auseinandersetzung mit Pornografie. Spätestens mit dem Erscheinen von Linda Williams' Buch "Hard Core" 1989 hat sich Schritt für Schritt eine differenzierte medien- und kulturwissenschaftliche Forschungslandschaft der Porno-Studies entwickelt. Rosa Danner versucht in ihrem Text einen roten Faden durch dieses Feld zu spannen und gibt einen Aufriss der zentralen Herangehensweisen. In einem zweiten Schritt fasst sie die prägnantesten Momente der genretypischen Medieninszenierung zusammen und versucht sie mit den Begriffen Pornotopia und Pornonormativität zu fassen. Ihr Hauptaugenmerk liegt dabei auf zeitgenössischen Mainstream-Hardcore-Pornofilmen.

Publisher: name: Nigerian Medical Journal
Year: 2025

description: Background: For methods that report quantitatively, an assessment of their imprecision and bias should be assessed in the laboratory before their deployment into routine service. This study assessed these parameters of the HbA1C method on the STANDARD F2400® point of care analyzer. These parameters were further combined to generate sigma metrics for the method.

 

Methodology: An external quality assurance (EQA) material from the Randox International Quality Assessment Scheme (RIQAS) was analysed according to the EP15 protocol of the Clinical Laboratory Standards Institute in SYNLAB Nigeria Laboratory Quality Assurance Department. Estimates of precision and an assessment of bias were determined from the data which consisted of 5 replicates per day for 5 consecutive days. Precision estimates were compared with manufacturer-provided information and estimates of bias were compared with the verification interval for the target value provided by RIQAS. Sigma metrics were determined for total allowable error (TAE) of 8% and 10%.

 

Results: The grand mean (standard deviation) for the study was 4.95 (0.15) %. The Within-run CV and within laboratory CV were 1.28% and 1.86%, respectively. These were within the manufacturer claims of 1.70% and 1.90%, also respectively. The target value by RIQAS was 5.04(0.24) % with a calculated verification interval of 4.95 - 5.13%. The sigma metrics for the method at TAE of 8% and 10% were 4.8/3.3 and 6.3/4.3 within the run/within laboratory estimates respectively.

 

Conclusion: The HbA1C method on the STANDARD F2400® Analyzer displayed performance characteristics that are consistent with manufacturer specifications and are above industry standard quality for a point-of-care device for HbA1C. These suggest that may be used to support routine monitoring of persons with diabetes mellitus in Nigeria.

description: Background: A mother's sociodemographic characteristics influence her practice of breastfeeding and are vital in determining the overall well-being of the baby. This study assessed the sociodemographic predictors of the knowledge and practice of exclusive breastfeeding among lactating mothers attending primary health centres in Ethiope West LGA of Delta State.

 

Methodology: This cross-sectional questionnaire-based study was conducted among 360 mothers of children aged 6-15 months attending six primary health centres in Ethiope West Local Government Area of Delta State. Data was collected on sociodemographic factors, knowledge, and practice of exclusive breastfeeding among mothers. There were 8 questions that assessed the knowledge of exclusive breastfeeding. A mother was assessed to have good knowledge of exclusive breastfeeding when she answered correctly at least 6 out of the 8 questions. Data was analyzed using IBM SPSS Version 26.0.

 

Results: The respondents were aged 15-41 years with the majority (47.4%) being 20-29 years and a mean age of 28.92±6.89 years. They were mainly Urhobos (62.8%), married (78.9%), with about half (50.6%) of the participants in the lowest social class and about 43.3% having at least a secondary education. Most (78%) respondents had a good knowledge of exclusive breastfeeding but only about one-third (36%) were exclusively breastfed. Logistic regression analysis showed the odds of practicing EBF to be about twice in married women compared to the unmarried (AOR= 1.90, 95% CI= 1.007-3.591, p=0.014) and that the level of education was predictive of knowledge of EBF (AOR= 12.89, 95% CI= 4.006-40.901; p=0.001).

 

Conclusion: Despite the good knowledge of EBF, its practice was poor with marital status being the most important predictor of EBF.

On the nature of job involvement : an inquiry into its antecedent and consequent conditions
Creators: name: Baba, Vishwanath Venkataraman
Publisher: name: University of British Columbia
Year: 2010

description: The study undertook to examine empirically the casual influence of certain individual difference factors and situational factors on job involvement and the effect of job involvement on job related effort. In addition, the role of certain individual difference and situational factors as moderators on the above linkage was explored. A theoretical model was developed with need for achievement, locus of control, job scope and participation in decision making as casual antecedents of job involvement and job related effort as its consequence. The moderator effects of age, education, sex and leader behavior on the above linkage were also studied. The model hypothesized a positive relationship between job involvement and need for achievement, internal locus of control, job scope, participation in decision making, and job related effort. In addition, the causal linkage was expected to be stronger for: 1. older people, 2. more educated workers, 3. males, and 4. those who function in a leadership climate of high consideration and structure. Data were gathered from two different groups through structured questionnaires. The pilot sample consisted of employees from organizations in the electronics industry located in the greater Montreal area. The validation sample consisted of people enrolled in the evening program in business administration in the two major anglophone universities in Quebec. All of them held full time jobs. Only anglophone respondents were included in the analysis. The pilot sample size was 139 with a response rate of 47% while the validation sample size was 170 with a response rate of 68%. Convergent and discriminant validation and internal consistency reliability tests indicated that the scales used in this study possessed acceptable psychometric properties. Path analysis, correlations and subgroup analysis were used to test the various hypotheses generated in this study. The results offered only moderate support to causal model originally proposed. The hypotheses suggesting positive relationships between the predictors and the criterion variables were all confirmed. Age, education, sex and leadership behavior failed to moderate the causal linkage in the hypothesized direction. There were no significant moderator effects. Based on the empirical findings, the original model was revised and tested. The results endorsed the validity of the revised model. The implications of the findings were discussed and possible future courses of action outlined.

description: Resumo – A formação da drenagem transcontinental do Rio Amazonas, fluindo para o Oceano Atlântico moldou a construção da paisagem física do norte da América do Sul. Depósitos sedimentares do leste da Amazônia, principalmente na região do Marajó, constituem importante registro das mudanças da paisagem nas terras baixas da Amazônia, pois integram toda a bacia de drenagem. A caracterização geomorfológica, através de análise de imagens de sensores remotos permitiu destacar que o vale fluvial do Rio Amazonas tem orientação NE-SW, limitado por áreas topograficamente mais elevadas. Os terrenos elevados são caracterizados por platôs sustentados por paleosolos de crostas bauxitica-lateríticas com elevação acima dede 50 m. Dois terraços fluviais abandonados (T3 e T2) e a planície fluvial ativa (T1) registram eventos de agradação e incisão fluvial desde o Mioceno Tardio. O protocolo de datação utilizando o sinal de luminescência opticamente estimulada de transferência térmica permitiu determinar as idades mais antigas associadas a depósitos do Rio Amazonas. Os depósitos do terraço T3 possuem elevação de 30 a 50 m, intensamente intemperizados e com idades que variam de 944 ka a 2.3 Ma. Os depósitos do terraço T2 ocorrem em elevação de 25 a 30 m, em uma extensa área plana. O protocolo de datação utilizando o sinal infravermelho de grãos de feldspato permitiu identificar uma fase de incisão e agradação fluvial por volta de 557 a 140 ka. Os dados de sensibilidade indicam que os depósitos fluviais apresentam sensibilidade similar aos de rios que transportam sedimentos com mistura de sedimentos andinos e cratônicos, tal qual ocorre atualmente no Rio Amazonas. Assim, no Leste de Amazônia, a migração lateral do canal em um vale restrito configurou a reciclagem de sedimentos, transferidos predominantemente para a região da foz e Gráben do Marajó. Além da topografia, os platôs representam unidades mais resistentes à erosão pela presença de crostas de intemperismo do leste da Amazônia. O ordenamento estratigráfico de depósitos ao longo do vale e depósitos do Gráben do Marajó, que apresentam elevada espessura, pode permitir a correlação destes eventos e ainda um melhor ordenamento dos eventos final de instalação do Rio Amazonas.

description: Resumo Seguindo a perspectiva do currículo em espiral de Jerome Bruner (1973), diversas atividades vêm sendo elaboradas para serem aplicadas nas disciplinas de Química Geral dos cursos de Ciências- Licenciatura e Ciências Ambientais da UNIFESP- (Campus Diadema) visando a aprendizagem do conceito de ligações químicas através de abordagens que empreguem cristais e /ou minerais. Fazem parte das atividades aplicadas até o momento, no contexto do ensino remoto, alguns vídeos demonstrativos: 1) recristalização de sólidos com materiais fácil acesso; 2) ensaios envolvendo o aquecimento de diversos tipos de sólidos/cristais e a condutividade/condutibilidade elétrica desses materiais à seco e em meio aquoso; 3) determinação da entalpia de dissolução de sólidos iônicos e 4) precipitação de silicatos (esse experimento é conhecido como “Jardim de Silicatos”). No tocante aos outros tipos de atividades já executadas, destacam-se as simulações com o software Crystalwalk e as pesquisas que buscam correlacionar a tabela periódica e as funções inorgânicas com as constituições químicas dos minerais. Os primeiros resultados coletados indicam que pouquíssimos discentes conseguem representar estruturas cristalinas dos cristais/sólidos: a imensa maioria sequer tenta representar algo. Diante desse cenário, fica claro a necessidade de novas atividades que fomentem a visualização e compreensão de estruturas e retículos cristalinos. Como exemplos dessas atividades, podem ser mencionados aqui o uso de esferas de isopor na construção de estruturas e retículos cristalinos, a intensificação das simulações – empregando também os softwares Mercury e ConQuest – e inserção de discussões a partir de propriedades físicas dos minerais (dureza, clivagem, fratura, entre outras).

description: Resumo A palinologia se destacada, nas últimas décadas, como uma ferramenta eficaz para a correlação bioestratigráfica e reconstruções paleoecológicas de bacias sedimentares. Esta análise é particularmente efetiva em sequências cretáceas de bacias marginais brasileiras A evolução destas bacias durante o Albiano-Aptiano é coincidente com a fase pós-rifte da abertura do Oceano Atlântico Sul e, portanto, favoreceu a acumulação de matéria orgânica. Os depósitos marinhos da Formação Romualdo (Grupo Santana), Aptiano da Bacia do Araripe, no nordeste brasileiro, são um exemplo de possível prospecto cujo conteúdo micropaleontológico permanece pouco compreendido. Este trabalho analisa o conteúdo palinológico da Formação Romualdo com o objetivo de construir um arcabouço bioestratigráfico e pretende-se reconstituir as condições paleoecológicas que permitiram a acumulação e preservação dos microfósseis. Para isto, foram coletadas 32 amostras em duas seções da Formação Romualdo para tratamento palinológico, foram confeccionadas 320 lâminas, e lidas 160 lâminas. Amostras provenientes de siltito, folhelhos pretos e calcário apresentaram recuperação de palinomorfos permitindo o reconhecimento de palinomorfos característicos do Cretáceo Inferior. O conteúdo fóssil analisado é composto, predominantemente, por: grãos de pólen, esporos, cistos de dinoflagelados, matéria orgânica particulada e amorfa, fitoclastos translúcidos e opacos (com destaque para cutículas bem preservadas), alga Botryococcus braunii e elementos de origem Incertae sedis. Existe um domínio do grupo Rimualdo gênero Classopolis (Pflug, 1960) (gimnospermas, Família Cheirolepidiaceae), que chega a 80% das contagens. As espécies identificadas foram Classopollis brasiliensis (Herngreen 1975), Classopollis alexi (Burger, 1965), Classopollis torosus (Burger, 1965) e Classopollis classoides (Fensome, 1983), além de pólens que foi possível classificar até gênero, denominados Classopollis spp.. A ocorrência de Botryococcus braunii associada a cutículas de Pseudofrenelopsis, dinoflagelados e a abundância das diferentes espécies do gênero Classopollis sugere ambiente continental lacustre (marinho proximal) para deposição destas sucessões com águas calmas, indicadores de água doce associados com condições marinhas. Com a descrição de todas as lâminas, espera-se montar um arcabouço crono e bioestratigráfico, com interpretação das condições paleoecológicas e avaliação paleogeografia do Gondwana Oeste durante o Aptiano.

description: In this paper, we present a conditional multitask learning method for end-to-end neural speaker diarization (EEND). The EEND system has shown promising performance compared with traditional clustering-based methods, especially in the case of overlapping speech. In this paper, to further improve the performance of the EEND system, we propose a novel multitask learning framework that solves speaker diarization and a desired subtask while explicitly considering the task dependency. We optimize speaker diarization conditioned on speech activity and overlap detection that are subtasks of speaker diarization, based on the probabilistic chain rule. Experimental results show that our proposed method can leverage a subtask to effectively model speaker diarization, and outperforms conventional EEND systems in terms of diarization error rate.

description: For any finite group G, we define a bivariant functor from the Dress category of finite G-sets to the conjugation biset category, whose objects are subgroups of G, and whose morphisms are generated by certain bifree bisets. Any additive functor from the conjugation biset category to abelian groups yields a Mackey functor by composition. We characterize the Mackey functors which arise in this way.

description: A Rashba type spin-orbit splitting is found for quantum well states formed in ultrathin Pb films on Si(111). The resulting momentum splitting is comparable to what is found for semiconductor heterostructures. The splitting shows no coverage dependency and the sign of the spin polarization is reversed compared to Rashba splitting in the Au(111) surface state. We explain our results by competing effects at the two boundaries of the Pb layer.

description: The purpose of this paper is to develop a synthesis theory for linear dynamical quantum stochastic systems that are encountered in linear quantum optics and in phenomenological models of linear quantum circuits. In particular, such a theory will enable the systematic realization of coherent/fully quantum linear stochastic controllers for quantum control, amongst other potential applications. We show how general linear dynamical quantum stochastic systems can be constructed by assembling an appropriate interconnection of one degree of freedom open quantum harmonic oscillators and, in the quantum optics setting, discuss how such a network of oscillators can be approximately synthesized or implemented in a systematic way from some linear and non-linear quantum optical elements. An example is also provided to illustrate the theory.

Medienpädagogik im Spannungsfeld der (Re)Produktion heteronormativer Machtstrukturen und emanzipatorischer Bildungsideale - Eine poststrukturalistische Perspektive

description: Gendersensibilität ist seit einigen Jahren zu einem beliebten Schlagwort avanciert, das von verschiedenen Disziplinen mehr oder weniger informiert aufgenommen wurde. Dieser Beitrag thematisiert aus einer poststrukturalistischen Perspektive, wie es um die Genderkompetenz medienpädagogischer Wissenschaft und Praxis bestellt ist und zeigt Möglichkeiten der Dekonstruktion heteronormativer Logiken im medienpädagogischen Feld auf. Im Hinblick auf Mechanismen und Praktiken der (Re)Konstruktion von Geschlechterdifferenz (re-)produzierenden Macht- und Herrschaftsstrukturen, werden die Beziehungen zwischen Medien und (medien)handelnden Subjekten sowie auch die Konstruktion medialer Diskurse am Beispiel des Phänomens #Gamergate betrachtet, um solche Lesarten und Praktiken im (Um)Gang mit Medien sowie innerhalb der Medienpädagogik kritisch zu hinterfragen, die Heteronormativität unkritisch reproduzieren und dadurch bestehende Geschlechterstereotype stützen. Darauf basiert die abschließende Forderung nach der Integration gendertheoretisch informierter Perspektiven in die akademische und praktische Medienpädagogik, denn nur so kann der selbstauferlegte Anspruch einer emanzipatorisch-kritischen (Medien)Bildung eingelöst werden.

Publisher: name: Medienimpulse
Year: 2017

description: Der Beitrag behandelt film- und fernsehbedingte Ängste in der frühen Kindheit und deren pädagogische Konsequenzen. Dabei werden Möglichkeiten zum Umgang mit schon vorhandenen Ängsten sowie insbesondere Möglichkeiten zur Angstprävention aufgegriffen. So wird erörtert, warum für eine Film- und Fernseherziehung in der frühen Kindheit stets auch bewahrpädagogisch orientierte Maßnahmen, die Verbote bestimmter Sendungen einschließen, wichtig sind. Zur Verdeutlichung wird auf Besonderheiten der frühkindlichen kognitiven Entwicklung aufmerksam gemacht, die mit einer möglichen Angst-Auslösung in Verbindung stehen. Zudem werden typische furchteinflößende Darstellungsmerkmale in fiktionalen Sendungen sowie typische Angstreaktionen in der frühen Kindheit beschrieben. Außerdem wird der Stellenwert offizieller Altersfreigaben und sonstiger Kinder- und Jugendschutzmaßnahmen zur Angstprävention diskutiert. Schließlich werden fünf konkrete erziehungsbezogene Hinweise für Eltern und sonstige Bezugspersonen formuliert.

description: Purple urine bag syndrome (PUBS) is an unusual presentation of urinary tract infection (UTI). Few cases have been reported in Africa. We present a case report of Purple Urine Bag Syndrome from the Niger Delta region of Nigeria. The patient was a bedridden catheterized 71 -year-old quadriplegic female patient with a history of hypertension, and ischemic stroke. She was treated with a course of appropriate antibiotics and by changing her urinary catheter and bag. The patient’s caregiver refused further care and signed against medical advice after forty-eight hours of admission without doing the requested investigations. Purple urine bag syndrome (PUBS) is a rare benign condition with a good prognosis.

description: We discuss the formation of stellar mass black holes via protoneutron star (PNS) collapse. In the absence of an earlier explosion, the PNS collapses to a black hole due to the continued mass accretion onto the PNS. We present an analysis of the emitted neutrino spectra of all three flavors during the PNS contraction. Special attention is given to the physical conditions which depend on the input physics, e.g. the equation of state (EoS) and the progenitor model. The PNSs are modeled as the central object in core collapse simulations using general relativistic three-flavor Boltzmann neutrino transport in spherical symmetry. The simulations are launched from several massive progenitors of 40 and 50 solar mass. We analyze the electron-neutrino luminosity dependencies and construct a simple approximation for the electron-neutrino luminosity, which depends only on the physical conditions at the electron-neutrinosphere. In addition, we analyze different mu/tau-neutrino pair-reactions separately and compare the differences during the post-bounce phase of failed core collapse supernova explosions of massive progenitors. We also investigate the connection between the increasing mu/tau-neutrino luminosity and the PNS contraction during the accretion phase before black hole formation. Comparing the different post bounce phase of the progenitor models under investigation, we find large differences in the emitted neutrino spectra. These differences and the analysis of the electron-neutrino luminosity indicate a strong progenitor model dependency of the emitted neutrino signal.

description: Aotearoa New Zealand’s high research overheads are internationally anomalous, and are over 100% of directly accounted for research costs such as salary, consumables and operating expenses. This means that the majority of taxpayer-derived funding provided by the Government to public institutions is difficult or impossible to properly account for. They also serve as a constant source of tension and confusion for all international migration and collaboration in the research sector.
The effect of localized new Higgs doublet on the radiative lepton flavor violating decays in the Randall Sundrum background

description: We study the radiative lepton flavor violating l_1->l_2γdecays in the two Higgs doublet model with localized new Higgs doublet in the Randall Sundrum background. We estimate the contributions of the KK modes of new Higgs bosons and left (right) handed charged lepton doublets (singlets) on the branching ratios of the decays considered. We observe that there is an enhancement in the branching ratios with the addition of new Higgs boson and lepton KK modes.

description: The determination of effective temperature for chemically peculiar (CP) stars by means of photometry is a sophisticated task due to their abnormal colours. Standard calibrations for normal stars lead to erroneous results and, in most cases corrections are necessary. In order to specify appropriate corrections, direct temperature determinations for 176 objects of the different subgroups were collected from the literature. This much larger sample than in previous studies therefore allows a more accurate investigation, mostly based on average temperatures. For the three main photometric systems (UBV, Geneva, Stromgren uvbybeta), methods to determine effective temperature are presented together with a comparison with former results. Based on the compiled data we provide evidence that He (CP4) objects also need a considerable correction, not noticed in former investigations due to their small number. Additionally, a new relation for the bolometric correction and the capability of standard calibrations to deduce interstellar reddening for magnetic CP stars are shown.

The logical imagination: the novels of Virginia Woolf
Creators: name: Baillargeon, Gerald Victor
Publisher: name: University of British Columbia
Year: 2010

description: Beginning with the premise that Virginia Woolf's novels exhibit a dual perspective of psychological mimesis and apocalyptic allegory, this dissertation formulates a critical theory of vision which operates on literary principles extracted, with a number of modifications, from two studies of Romantic transcendence: Thomas Weiskel's The Romantic Sublime: Studies in the Structure and Psychology of Transcendence, and the Second Essay of Northrop Frye's Anatomy of Criticism. The narrative role of the Woolfian "moment of being" is explored in her nine novels as a fictional analogue of Weiskel's "sublime moment," a metaphorical subplot in which the harmonious relation between the self and nature breaks down. When the moment of being does not merely collapse into a cycle of nature worship, it follows an Oepidal path of reactive identification in which the character identifies with the prevailing cultural pattern, or "father." Thus the fictional character experiences the moment of being as a failed psychological transcendence. From the perspective of apocalyptic allegory, these novels engage the imagination of the reader by means of the "logical imagination": that is, the poetic Logos becomes-, the anagogic Word. This revolutionary concept of apocalypse is adapted from the theory of symbols that Frye discusses in Anatomy of Criticism, where the "anagogic symbol" is identified with the divine Word. In Woolf's allegory, "there is no God; we are the words" (Moments of Being, 72). The view of Woolf's vision as a dual perspective implies that Woolf advocated, and developed, fictional forms that juxtapose realistic and mythopoeic constructs. Her characters, plots, and settings represent life in this world as a failed transcendence, while her mythical and metaphorical structures define for the reader an imaginative apocalyptic quest having five identifiable stages: 1) the presentation of an inner psychological realm where the imaginary and the real seem inextricable, 2) the discovery of the "out there" as a solid basis for imaginative identity, 3) the exploration of a crisis of vacancy out of which the imaginative self becomes reborn, 4) the establishment of an imaginative pattern as a prelude to the rejection of the "fatherhood" influence of history and society, and 5) the apocalyptic awakening of "ourselves" from the dream of history and of selfhood. From the investigation of these developments in Woolf's vision emerges a distinct novelistic canon. This study, as a whole, documents Virginia Woolf's "own particular search--not after morality or beauty or reality--no ; but after literature itself" (The Diary of Virginia Woolf, I, 214).

description: Background: Epilepsy is a chronic neurological disorder that disrupts daily life and negatively impacts quality of life (QOL). While most medical approaches focus on seizure control, there is limited attention to the QOL of children with epilepsy (CWE) in eastern India. This study aimed to assess QOL among CWE and examine the influence of socio-demographic factors, seizure characteristics, and parental awareness of a seizure action plan (SAP).

 

Methodology: This cross-sectional study was conducted in the Department of Paediatrics at a tertiary care teaching hospital in eastern India from December 2020 to May 2022. Eighty children aged 5-15 years, all diagnosed with epilepsy and on antiepileptic medication for at least six months, participated. Approval was obtained from the Institutional Ethics Committee of the concerned hospital. The participants were interviewed using a structured pre-tested schedule. The QOL of the participants was evaluated using the Quality of Life in Childhood Epilepsy (QOLCE-55) questionnaire. Parental awareness of SAP was assessed based on their knowledge of essential seizure management actions. Kruskal Wallis test was used to identify factors associated with QOL.

 

Results: The mean age in the study population was 9.37 ± 3.57 years, with 56.45% males. The mean QOL scores in cognitive, emotional, social, and physical domains were 59.41, 55.11, 56.40, and 65.11, respectively. QOL steadily declined with age, with emotional and social domains more impacted in older children. Maternal illiteracy, low socioeconomic status, and earlier onset of epilepsy were significantly associated with poorer QOL (p<0.001). Only 21.25% of parents had complete awareness of SAP, and the children of these parents had relatively better QOL scores.

 

Conclusion: QOL was better in CWE who were younger, had late-onset epilepsy, belonged to the upper socioeconomic class, and whose mothers were educated. Interventions enhancing parental awareness about SAP may lead to improvement in the QOL of CWE.
