Relationship between Intelligence Quotient, Academic Motivation and Academic Performance in Secondary School Students

Background: Students’ academic performance is affected by personal factors such as students’ effort, previous schooling, parent’s educational background, self motivation and intelligence. Aim: To determine how academic motivation and intelligence quotient uniquely contribute to differences in students' academic performance. Study Design: This was a cross-sectional descriptive study. Methodology: The study was carried out on 405 selected students from both private and public secondary schools in Enugu-East Local Government Area, study participants aged 9 through 15 years which is within the eligible ages for the Raven Standard Progressive Matrices. Academic scores in three subjects were obtained from the schools. Intelligence quotient was measured using Raven Standard Progressive Matrices and Academic motivation was measured using the Academic motivation scale modified for use among secondary school students. A self-administered questionnaire was used to obtain data on age, gender and parent’s educational level. Results: Approximately 50% of study participants had an IQ 100 and above and 7.5% were intellectually superior scoring above the 95th percentile. IQ and academic motivation significantly predicted academic performance accounting for 29.9% of variance in academic performance(p<0.001). Conclusion: Academic motivation plays a role in students’ success and academic performance. IQ alone does not account for the differences in academic performance among students.

The estimation of this interval is a matter of great relevance in the forensic sphere due to its important role in the resolution of criminal cases. Teeth are fundamental structures in a forensic context due to their high strength and specificity. Therefore, this article aims to present how the dental pulp is used to determine the time of death of the corpse. A systematic review of the scientific literature was carried out with a descriptive and qualitative character, allowing the inclusion of experimental and non-experimental studies for a complete coverage of the analyzed phenomenon. For data collection, online searches were carried out on the bases: SciElo, LILACS and Elsevier. All journal papers that used the selected terms were included in this review. The degradation of dental pulp after death consists of a complex process that has not been fully studied, but with the techniques and changes shown in the text, reliable post-mortem interval results are possible.
The Gender Role Attitude Scale (GRAS) as an alternative for the crisis in measurement of attitudes towards gender roles in Latin America: A study in Chilean university students

Hemos experimentado cambios socioculturales que han favorecido el desarrollo de actitudes de roles de género (GRA) más igualitarias. Sin embargo, actualmente la revolución en los roles de género está incompleta y la falta de equidad en las estructuras sociales limita las experiencias individuales en igualdad. Ante esta realidad, la comunidad científica exige un sistema modernizado para medir GRA. Presentamos adaptación, evidencia de validez factorial y convergente, precisión, efecto techo y piso, normas de interpretación por sexo, y análisis del GRA más fácil y difícil de modificar, para la Escala de Actitudes de Rol de Género (EARG) en muestra de 1013 universitarios chilenos. La EARG tiene una estructura bifactorial que evalúa actitudes estereotipadas y trascendentes en contextos familiares, sociales y laborales. Presenta validez convergente con una medida de doble estándar sexual y es más confiable en puntajes bajos de trascendencia y puntajes altos de actitudes estereotipadas. El factor trascendente tuvo un efecto techo, y las actitudes estereotipadas un efecto suelo. Los roles familiares de género son los más fáciles de cambiar, y los relacionados con el trabajo los más difíciles. Se discute la necesidad de un cambio estructural para reactivar la revolución de los roles de género en Chile. We have experienced sociocultural changes, which have favoured the development of egalitarian gender role attitudes (GRA). Nevertheless, the revolution in gender roles is incomplete, and the lack of equity in social structures limits the individual experiences in equality. In the face of this reality, the scientific community is demanding a modernised system for measuring GRA. We present adaptation, evidence of factorial and convergent validity, accuracy, ceiling and floor effect, norms of interpretation by sex, and analyses of the GRA easiest or most difficult to modify, for the Gender Role Attitudes Scale (GRAS) in a sample of 1013 Chilean university students. The GRAS has a two-factor structure that allows the evaluation of stereotyped and transcendent attitudes of gender roles in family, social, and work contexts. The scale presents convergent validity with a sexual double standard measure and is more reliable in the low scores of transcendence and the high scores of stereotyped attitudes. Transcendent factor had a ceiling effect, and stereotyped attitudes had a floor effect. Family gender roles are the easiest to change, and work-related roles the most difficult. The authors discuss the need for a structural change to reactivate the revolution of gender roles in Chile.
Differences in radiotherapy application according to regional disease characteristics of hepatocellular carcinoma

There are differences in opinion regarding the application of external beam radiotherapy in the treatment of hepatocellular carcinoma. Some major guidelines state that external beam radiotherapy is yet to attain a sufficient level of evidence. However, caution should be exercised when attempting to understand the clinical need for external beam radiotherapy solely based on the level of evidence. Previously, external beam radiotherapy had low applicability in the treatment of hepatocellular carcinoma before computed tomography-based planning was popularized. Modern external beam radiotherapy can selectively target tumor cells while sparing normal liver tissues. Recent technologies such as stereotactic body radiotherapy have enabled more precise treatment. The characteristics of hepatocellular carcinoma differ significantly according to the regional etiology. The main cause of hepatocellular carcinoma is the hepatitis B virus. It is commonly diagnosed as a locally advanced tumor but with relatively preserved hepatic function. The majority of these hepatocellular carcinoma cases are found in the East Asian population. Hepatocellular carcinoma caused by hepatitis C virus or other benign hepatitis tends to be diagnosed as a less locally aggressive tumor but with deteriorated liver function. The western world and Japan tend to have patients with such causes. External beam radiotherapy has been more commonly performed for the former, although the use of external beam radiotherapy in the latter might have more concerns with regard to hepatic toxicity. This review discusses the above subjects along with perspectives regarding external beam radiotherapy in recent guidelines.

3-D Face Landmark Detection using Multitask Hourglass Model

Even though state-of-the-art 2-D face alignment meth-ods have shown near saturating performance, solving face alignment based on 3-D structure of face from 2-D image remains challenging problem. 3-D face landmarks, which correspond with 2-D projection of face structure have advantage over 2-D landmarks of preserving correspondences across poses. In order to try to solve this task more effectively, a multi-task Hourglass model is proposed, which combines the state-of-the-art convolutional neural network model Hourglass with multi-task learning in form of learning facial landmarks and face pose simultaneously, where the pose is represented by Euler angles. Experiments on dataset AFLW2000-3D show that the results of multi-task Hourglass improve the results compared to single-task Hourglass, learned on landmarks only.
Can transit enable better and more equitable urbanity?

Nordic welfare states once sought to provide their citizens with affordable and healthy urban environments by planning compact residential areas. For a variety of reasons, this model is now in a major rupture. Strong domestic and international migration to 4-6 urban regions transforms Finland’s spatial setup. The entire process entails major challenges for urban design. Expanding urban structures constitute a massive source of greenhouse gases and are often deemed dysfunctional for reaching goals such as social sustainability, better public health or even individually perceived quality of life. Transit-oriented development (TOD) is one of the attempts to tackle these challenges. Now it holds a major promise for better and more equitable urbanity, but this assumes that the entire dynamics of urban development and how transit and better accessibility are related to it will be re-thought. This paper is based on case-study data from Tampere city region and its on-going light rail transit (LRT) construction process as an example of the current TOD thinking. It also makes references to comparable or otherwise interesting international LRT processes as discussed in planning journals or based on the authors’ own observations and fieldwork.
Differences in the Usage of Credit Guarantees Across Banks

We investigate differences in the use of credit guarantees among banks by using a bank-firm matched dataset from Japan. By following Khwaja and Mian (2008) to control for borrower characteristics and the supply factors of guarantees using firm fixed effects, we extract the part of the ratio of guaranteed loans to total loans that depends solely on banks' factors for the demand for guarantees. We find significant differences in this after-control ratio for some banks, and the distribution of the ratio is significantly different from that of an uncontrolled ratio based on publicly available data. We further find that the controlled ratio does not depend on the financial conditions of the respective banks such as the capital ratio of the banks, which indicates that other observable and/or unobservable bank characteristics determine these differences in the use of credit guarantees across banks.
C-type natriuretic peptide and its contribution to bone growth.

INTRODUCTION AND OBJECTIVE The expression of the C-type natriuretic peptide (CNP) gene has been detected in the growth cartilage of the long bones and vertebrae. This article provides an overview of the role of CNP in bone growth and presents the results of the authors' research on the concentration of the NTproCNP and its relationship with growth velocity and bone markers in healthy school-age children. MATERIAL AND METHODS The study involved 75 girls and 59 boys aged from 9.0-11.8 years (mean 10.29±0.74). Body weight, height and lower limb length were measured, and blood samples were collected twice at six-month intervals. In the first serum sample, the concentrations of NTproCNP, C-terminal propeptide type I (CICP), C-terminal telopeptide type I collagen (ICTP) osteocalcin (OC) and bone-specific alkaline phosphatase (BAP) were determined. In the second sample, NTproCNP concentration was assessed. RESULTS During the six-month follow-up period, the increase in body height and weight of girls was greater than boys (p<0.000; p=0.003, respectively). While during the first examination the concentration of NTproCNP in girls and boys was similar, during the second examination it was higher in girls than in boys (p=0.04). Weak positive correlations between the increase in body height and NTproCNP, CICP, BAP as well as OC were found. There were no correlations between NTproCNP and the bone markers. CONCLUSIONS The results suggest that NTproCNP concentration depends on growth velocity in children. There is increasing evidence that a better knowledge of CNP biology contributes to a better understanding of bone growth mechanisms.
Supercritical Carbon Dioxide Extraction of Apigenin from Parsley Leaves Pre-treated to Maximize Yield

Apigenin is a bioactive ingredient found in many vegetables and herbs, especially parsley (Petroselinum crispum L.). It was successfully extracted at high yields from parsley leaves using supercritical carbon dioxide (SCCO2) without co-solvent. A strong correlation was especially apparent at high SCCO2 density. The amount of extracted apigenin was well correlated with the difference in solubility parameters between the solvent (SCCO2) and the solute (apigenin). A lower energy requirement for extraction resulted in a greater amount of extracted apigenin. Various pre-treatments of parsley leaves (particle size, drying method and hot-water soaking of the samples) were examined to maximize the amount of extracted apigenin. Soaking in hot-water and then freeze-drying of parsley leaves was an optimal pre-treatment to realize the maximum amount of extracted apigenin.
Psychometric properties of the Revised Children's Manifest Anxiety Scale-Second Edition in Peruvian students.

The aim of this study was to analyze the psychometric properties of the Revised Children’s Manifest Anxiety Scale–Second Edition (RCMAS-2) among Peruvian students. The sample consisted of 472 participants aged between 7 and 18 years, of whom 250 were female (53%). Likewise, 191 were enrolled from third to sixth grade of primary school (40.5%), and 281 were registered from first to fifth grade of secondary school (59.5%). The results of the study indicated that the RCMAS-2 scores had adequate levels of reliability for all its dimensions (ordinal alpha > .70). On the other hand, a four-factor structure (Physiological anxiety, Worry/Social anxiety, Defensiveness I, and Defensiveness II) was found to be invariant to gender and schooling level. Also, convergent and discriminant validity evidence was provided. Finally, a moderate difference in Defensiveness II according to the schooling level through the latent mean structure analysis was found. Taking into account the results, it was concluded that the RCMAS-2 scores have evidence of reliability, validity, and equity for its use in Peruvian regular elementary school students.
Explanatory sequential design of mixed methods research: Phases and challenges

The purpose of this essay is to discuss the phases and challenges of the explanatory sequential design (ESD hereinafter) of mixed methods research (MMR hereinafter) by reviewing relevant literature. The literature was explored during the design stage of a Ph.D. project that sought to examine the relationship among social capital, education, and employment for foreign students graduating from several Estonian universities. The review finds that the explanatory sequential design of MMR is much more complex than just sequencing how and what kind of data to collect; it also entails selecting how data will be processed and presented using a range of techniques that are often riddled with difficulties. By addressing these ideas, this paper will aid those interested in comprehending the summary of the explanatory sequential design of MMR.
Cardiac T-Tubule Membranes - Nanostructure and Remodeling Mechanisms in Disease

Transverse tubules (T-tubules, TTs) are continuous invaginations of the plasma membrane which form a complex network of excitable membranes inside mammalian ventricular cardiomyocytes. The TT network couples electrical with chemical signals in the relatively large cardiomyocytes and enables the synchronous rise of intracellular Ca2+ concentrations in response to membrane depolarization during systole. It is assumed that the functional coupling of voltage-dependent Ca2+ channels in the TT membranes and ryanodine receptor Ca2+ release channels in the junctional sarcoplasmic reticulum is essential to assure Ca2+ induced Ca2+ release. Previous studies reported changes of the TT structure in cardiomyocytes from diseased hearts. However, the methods used to visualize TTs were either diffraction limited (confocal microscopy) or restricted to fixed samples (electron microscopy). In this thesis, Stimulated Emission Depletion (STED) microscopy, a super-resolution technique, was used to quantitatively characterize TT membrane structures in living cardiomyocytes. Applying different image analysis strategies, the properties of individual TTs and the TT network in living healthy and diseased cardiomyocytes were quantified. Pathological TT changes were analyzed in two different mouse disease models, which were induced either by myocardial infarction (MI) or by transverse aortic constriction (TAC). Imaging and analysis of the TT nanostructure were complemented by functional measurements of intracellular Ca2+ transients and by the analysis of proteins which might play a role in TT remodeling. During heart failure (HF) development after MI, a progressive and heterogeneous enlargement of individual TT cross-sections was observed. In addition, length and complexity of the TT network progressively increased after MI. A significant increase of longitudinal TT elements was identified 4 weeks after MI representing an early time point of disease development. The observed TT remodeling was accompanied by differential expression changes of caveolin-3 and junctophilin-2. Furthermore, the differential spatial reorganization of TT elements correlated with a loss of intracellular Ca2+ release synchrony. Increased TT dimensions and proliferative TT network remodeling were also observed during HF development in the TAC model. These data suggest that TT remodeling after TAC may occur over a shorter period of time than TT remodeling after MI. This thesis introduces STED microscopy for imaging of intact TT membranes in living cardiomyocytes. Importantly, relatively early during HF development, individual TT elements and the cell-wide network properties are significantly altered through proliferative mechanisms. The data obtained here further suggest that TT remodeling during HF development might lead to excitation-contraction uncoupling, which can directly contribute to electrical and contractile dysfunction of diseased hearts.
A novel approach to prepare solvent-free cerium dioxide nanofluids

ABSTRACT This paper develops a novel approach to prepare solvent-free cerium dioxide (CeO2) nanofluids through N,N-didecyl-N-methyl-N-(3-trimethoxysilylpropyl) ammonium chloride covalently grafted on the surface of CeO2 nanoparticles as core, and then poly(ethylene glycol) 4-nonylpheny 13-sulfopropyl ether sodium salt was grafted on the surface of CeO2 nanoparticles through ion exchange reaction. It is obviously observed that CeO2 nanofluids exhibited a solid state at room temperature, whereas they behave as liquid-like when being heated to above 45°C. To detect the properties of CeO2 nanofluids, the morphology, thermal stability, dispersibility, and rheological behavior of CeO2 nanofluids are mainly investigated. It is found that CeO2 nanofluids can flow without solvent existence. Meantime, it shows good dispersion and stability in water and other organic solvents for weeks due to amphiphilic properties of the modifier molecules.
