Formulation of Learning Strategies Using Bigg’s (R-SPQ-2F) Thru Attitudinal Studies of Selected Nursing Students in Higher Education Institution

Background and objective: This research anchored on the formulation of learning strategies using Bigg’s (R-SPQ-2F) thru attitudinal studies of selected nursing students in terms of surface approach and deep approach. Further, the extent of motivation of the respondents that demonstrates in their attitudinal studies using Bigg’s (R-SPQ-2F) to prove the connection of their learning strategies and their drive to study. The correlation of the attitudinal studies of the respondents and the prepared motivation of Bigg’s (R-SPQ-2F) will help determine the students’ insight about their learning practices. This aims to determine the attitudinal studies with learning approaches of the nursing students, the results of which then will become the bases for enhancing the teaching strategies of teachers to upgrade the performance of the students. Methods: The study will take the form of descriptive-evaluative research. A survey was conducted using the standardized test (R-SPQ-2F) questionnaire as propagated by John Biggs for information gathering about respondents profile and their attitudes towards learning. This study is a combination of quantitative and qualitative research, also, this will take the form of an applied type of research, and thus, teachers consequently facilitate low-achieving nursing students perform better in the subject. The study used a statistical tool for the interpretation of results according to sub problems such as frequency distribution, percentage, ranking, weighted mean, likert scale, and f-test. Results: The results revealed that there are significant differences concerning the attitudinal studies of the selected nursing students in terms of surface approach and deep approach. The motivation of the nursing students using Bigg’s (R-SPQ-2F) manifested that their extent of attitudinal studies are well equipped through academic awareness. There are twelve (12) motivational Approaches of the nursing students that are correlated to the Bigg’s (R-SPQ-2F) and eight (8), which are not correlated under deep approach and surface approach. Thru evident findings, the Learning Strategies that are formulated are based on the Extent of Motivational Approach of the nursing students through their attitudinal Studies using Bigg’s (R-SPQ-2F). Conclusions: The results analysis signifies that the attitudes toward learning have been influence students’ scholastic performance. This result manifested that the extent of the attitudinal studies of the nursing students are well-equipped through academic awareness. The result encompasses change and development through the developmental stages of the nursing students. This implies that educators should become aware of the efforts of students made for learning in order for them to reach knowledge. It is important to know the ways of learning, develop expectations and have no anxiety for learning in order to be successful.
Temporal Stability of the ACS/WFC OD-800W LED

This report summarizes an analysis of the ACS/WFC post-flash LED stability over a ∼4.5 year period. We analyze 1,294 post-flash calibration darks generated from January 2015 to July 2019. We find the observed intensity of the LED, relative to the intensity in January of 2015, to be declining at a rate of ∼ 0.2% per year. We use the resulting fit to the LED signal over time to compute a time-dependent normalization factor for each annual post-flash reference file. This normalization reduces the observed scatter between the post-flash reference files caused by short-term fluctuations in the intensity of the LED. The normalized post-flash reference files are currently available in the HST Calibration Reference Data System (CRDS).
Plant Extracts in Skin Care Products

Cymbopogon citratus (DC) Stapf is consumed as a popular decoction owing to its nice flavor and hypotensor property. Its aqueous extract radioprotector and antimutagenic properties have been experimentally demonstrated. In addition, its DNA protective activity against UV light has been proved in plasmid DNA and bacterial models. The fractioning process is important in order to identify phytocompounds responsible for this activity. In this work, the toxicity of three fractions obtained from Cymbopogon citratus (essential oils, butanolic and aqueous fractions) were tested using the SOS Chromotest in Escherichia coli. Cymbopogon citratus chemical fractions possess cytotoxic properties in E. coli in the following order butanolic > aqueous > essentials oils. Genotoxic properties were detected in any of the fractions.
GENETICAL VARIATION OF CALLUS PERFORMANCES OF MAIZE GENOTYPES PRODUCED FROM TISSUE CULTURE UNDER DIFFERENT LEVELS OF SALINITY.

Four maize hybrids (122, 168, 173 and pioneer) were investigated to determine their genotypic effects on callogenesis response to 2,4-D (2,4 dichlorophynoxyacetic acid) and in vitro salt tolerance using NaCl. A callus was initiated from mature embryos cultured on three MS media supplemented with 0, 2 and 4mg/l of 2,4-D where the level 0 is the control. The produced calli from the medium which contains 2 mg/L 2,4-D for each genotype were then exposed to four salinity levels (i.e. 0, 1500, 3000 and 6000 ppm) of NaCl, respectively to evaluate some physiological aspects of the produced calli from the genotypes. The results of ANOVA revealed that the mean squares of genotypes at all levels of 2,4-D were significantly indicated the presence of differences between them for all in vitro traits. Furthermore, the mean squares of levels and genotype × levels interaction were highly significant for all traits. This indicated that these genotypes gave different responses at different 2,4-D levels. The genetic variation was high and positive with respect to the in vitro traits at each 2,4-D level. This indicated that these traits are mainly controlled by genetic factors. This finding was emphasized by the heritability values, which were more than 80% for all studied traits at each 2,4-D level. In relation to callus response to salt stress, the results indicated that the presence of significant differences between these genotypes for ion content in callus cells (K + %, Na + %, Na + /K + and Cl %) with respect to the four salinity levels except for K + % at S1,S3 levels, Na + % at levels S1, S2, S3, Na + /k + at levels S0, S1, S3 and Cl % at levels S2, S3. Regarding to, the organic solutes accumulation (sugar and proline mg/g f.wt), the magnitudes of the mean squares for genotypes were significant at four salinity levels except for proline mg/g f.wt at S3 level. For membrane permeability, relative growth rate and water content, the magnitudes of the mean squares for genotypes were significant at four salinity levels except for water content at levels S0, S3.The results revealed that the genetic variation was high and positive for ion content in callus cells (K + %, Na + %, Na + /K + and Cl %), organic solutes accumulation (sugars and proline), membrane permeability and relative growth rate as well as water content with respect to the four levels of salinity. This finding is emphasized by the heritability values, which were more than 80% for most of studied traits.
Egypt's Capital Market Firm-Specific Fundamentals Pre-financial crisis

This study documents four factor sensititivities of excess returns in Egypt during the economic period from (2005-2007) which represent Pre-financial crisis economic environment. This study is placed within deductive research paradigm that evaluates the extent to which idiosyncratic risk factors organize market facts during (2005 -2007)that signifying the economic environment pre-financial crisis based on beta and firm-specific fundamentals, namely, size, value, and accounting earnings.

Ahmed Mohamed Moataz Abd El Salam عبارلا ددعلا قحلم سداسلا دلجملا 5108 976 Introduction: In this study, a proxy specifications of (Fama and French, 2014) four-factor model is estimated in order to produce stylized facts of the Egyptian market. The data set is the panel of all publicly traded firms, excluding financial and negative book value of equity firms. The capital asset pricing model aggregates all risk into only one risk factor which is the market risk because it assumes that all other risks can be removed through diversification. However, in reality there are many sources of risk that are not washed out through diversification, that investors should consider in determining risk-return relationship which is explained by Fama and French 2014. The contribution to the extant literature is two-fold: [1] organizing Egyptian market data based on beta and firm-specific fundamentals, namely, size, value, and accounting earnings. The study organizes Egyptian capital market facts based on four factors: market beta, size, value, and accounting earnings. In particular, documenting a factor loading for accounting earnings within an empirical asset pricing model defines a major contribution for this study. Unlike those pertaining to the first three factors, empirical documents of the accounting earnings factor loading are rather, if any, scant. The researcher stresses the style pioneered by Fama and French in terms of taking finance research away from pure hypothesis testing and learning directly from data. This is done in this study by spelling out empirical regularities of the Egyptian Egypt's Capital Market Firm-Specific Fundamentals Pre-financial .

Estimating treatment effect for individuals with progressive multiple sclerosis using deep learning

Modeling treatment effect could identify a subgroup of individuals who experience greater benefit from disease modifying therapy, allowing for predictive enrichment to increase the power of future clinical trials. We use deep learning to estimate the conditional average treatment effect for individuals taking disease modifying therapies for multiple sclerosis, using their baseline clinical and imaging characteristics. Data were obtained as part of three placebo-controlled randomized clinical trials: ORATORIO, OLYMPUS and ARPEGGIO, investigating the efficacy of ocrelizumab, rituximab and laquinimod, respectively. A shuffled mix of participants having received ocrelizumab or rituximab, anti-CD20-antibodies, was separated into a training (70%) and testing (30%) dataset, but we also performed nested cross-validation to improve the generalization error estimate. Data from ARPEGGIO served as additional external validation. An ensemble of multitask multilayer perceptrons was trained to predict the rate of disability progression on both active treatment and placebo to estimate the conditional average treatment effect. The model was able to separate responders and non-responders across a range of predicted effect sizes. Notably, the average treatment effect for the anti-CD20-antibody test set during nested cross-validation was significantly greater when selecting the model's prediction for the top 50% (HR 0.625, p=0.008) or the top 25% (HR 0.521, p=0.013) most responsive individuals, compared to HR 0.835 (p=0.154) for the entire group. The model trained on the anti-CD20-antibody dataset could also identify responders to laquinimod, finding a significant treatment effect in the top 30% of individuals (HR 0.352, p=0.043). We observed enrichment across a broad range of baseline features in the responder subgroups: younger, more men, shorter disease duration, higher disability scores, and more lesional activity. By simulating a 1-year study where only the 50% predicted to be most responsive are randomized, we could achieve 80% power to detect a significant difference with 6 times less participants than a clinical trial without enrichment. Subgroups of individuals with primary progressive multiple sclerosis who respond favourably to disease modifying therapies can therefore be identified based on their baseline characteristics, even when no significant treatment effect can be found at the whole-group level. The approach allows for predictive enrichment of future clinical trials, as well as personalized treatment selection in the clinic.
GDP and Temperature: Evidence on Cross-Country Response Heterogeneity

We use local projections to estimate the cross-country distribution of real GDP per capita growth impulse responses to global and idiosyncratic temperature shocks. Negative growth responses to global temperature at longer horizons are found for all Group of Seven countries while positive responses are found for seven of the nine poorest countries. Global temperature shocks have negative effects on growth for around half of the countries and seemingly anomalous positive effects for the other half. After controlling for latitude and average temperature, positive growth responses to global temperature shocks are more likely for countries that are poorer, have experienced slower growth, are less educated (lower high school attainment), less open to trade, and more authoritarian
A METAL-ANALYSIS STUDY OF MIND MAPPING EFFECTIVENESS IN ENGLISH LANGUAGE TEACHING AT A HIGHER EDUCATION INSTITUTION

Received: 03/4/2021 Teaching English is a demanding job, and the challenge to reform its pedagogical approaches requires educators to adapt themselves to constant changes in teaching. This study investigated the effectiveness of one typically practical mind map technique in English language teaching at the tertiary level, particularly a case study at a higher education institution – Hanoi Law University during the first term of the school year 2020-2021. The research was conducted as a quasiexperimental method, employing primary sources such as questionnaire and the analyzed results of pre-and-post tests. Almost teachers and students expressed high preferences for the implementation of mind map technique in English language teaching and learning. In addition, the results from the comparison between the experimental group and control one pointed out that mind map technique brought back positive academic performance in learning and teaching English. These research findings suggest that there should be more supportive policies to promote the use of mind map technique in the educational context, especially in English acquisition.

Hungry hosts? Refugee camps and host community nutritional outcomes in subSaharan Africa

We examine nutritional outcomes in host communities exposed to refugee camps within a multi-country difference-in-differences framework across sub-Saharan Africa (SSA). Our study uses new spatially explicit data on refugee camps in SSA merged with the Demographic and Health Surveys to estimate the cross-country average treatment effect of camps. To test against bias in the coefficients of interest under staggered treatment timing, we use a diagnostic test to evaluate treatment effect homogeneity. We find that being within 10 kilometers of a camp decreases children’s weight-for-age z-scores by 10 percent of the sample mean. Children with married household heads experience improved nutrition outcomes near camps. We consider adult loss of employment and worsening child health as explanatory mechanisms: we find no significant evidence of worsening child health or a reduction in employment opportunities. We argue that rising child malnutrition among hosts is due to the changing composition of the host population or to price shocks under localized price dispersal.
A rapid sedimentary response to the Paleocene-Eocene Thermal Maximum hydrological change: new data from alluvial units of the Tremp-Graus Basin (Spanish Pyrenees)

A massive emission of light carbon about 56 Ma ago, recorded in marine and terrestrial sediments by a negative carbon isotope excursion (CIE), caused a short-lived (~170 kyr) global warming event known as the Paleocene–Eocene Thermal Maximum (PETM). The core of this event is represented in the south Pyrenean Tremp-Graus Basin by two successive alluvial units, the Claret Conglomerate (CC) and the Yellowish Soils, which represent laterally juxtaposed depositional environments. It is generally agreed that these units record a dramatic increase in seasonal rain and an increased intra-annual humidity gradient during the PETM, but the timing of the sedimentary response to the hydrological change is a matter of debate. Some authors maintain that the CC was developed during the early, most intense phase of the carbon emission, others that its formation lagged by 16.5 ± 7.5 kyr behind the onset of the PETM. The latter claim was mainly based on the assumption that in two sections of this basin, Claret and Tendrui, the onset of the CIE occurs 3 and 8 m below the base of the CC, respectively. Here we show that in the zone between these two sections the CC is missing and the Yellowish Soil unit rests directly and conformably on the underlying deposits. New d13Corg data from this zone provide sound evidence that the onset of the CIE is situated just ~1 m below the Yellowish Soils. The CC erosional base cuts down deeper than this figure, rendering it highly unlikely the preservation of the CIE onset below it. A tentative estimate based on sedimentation rates indicates that ~3.8 kyr, or less, may have elapsed from the onset of the CIE to the arrival of PETM alluvium into the Claret-Tendrui study area, about a third of the lowest estimate of previous authors. Since the study area was situated about 15 km from the source area, our new estimate supports a rapid response of the sedimentary system to the hydrological change at the onset of the PETM.
The Role of Reward Sensitivity in the Perpetration of Reactive and Proactive Aggression

Research has implicated reward sensitivity as one potential shared mechanism underlying reactive and proactive aggression. The current study examined the effect of reward sensitivity, assessed multi-modally through a behavioral task and self-report, on the perpetration of reactive and proactive aggression assessed via a laboratory paradigm. Participants were 184 undergraduate men and women. Hierarchical linear regression revealed positive main effect of reward sensitivity on aggression that did not differ according to condition. This finding offers initial evidence for reward sensitivity as a common etiological correlate of reactive and proactive aggression. And supports future research on shared risk factors that could be targeted to reduce both reactive and proactive aggression.

Information and Communication Technologies and Sustainable Livelihood Opportunities: A Study of Information Behavior Among Malaysian Youth

Information and communication technology (ICT) is a significant instrument for youth empowerment, since it allows instant interaction, thus enabling information needs and community development. This study aims to explore the cumulative knowledge on how youths use ICT as an essential part of their daily lives. A quantitative study was carried out and the data were analyzed by the structural equation modeling technique (SEM). The results confirmed that information needs and sharing have a positive influence on the sustainable livelihood of Malaysian youth. However, the findings also reveal that there was no significant relation between two of these predictors (i.e. information seeking and information source) and the sustainable livelihoods of Malaysian youth. Due to its unique perspective, this study contributes to the existing literature on youth information behavior in ICT environments.
The Dynamics of the Interrelationships between Conscious Self-regulation, Psychological Well-being and School-related Subjective Well-being in Adolescents: A Three-year Cross-lagged Panel Study

Background Recently, research on psychological well-being and its dynamics and predictors in adolescence, has gained special attention, due to the importance of well-being for mental and physical health, as well as for success in different activities. Self-regulation (SR) is considered a significant resource for maintaining psychological and school-related subjective well-being. Objective The purpose of our study was to identify the role of conscious SR in maintaining pupils’ satisfaction with school life, and to assess the contribution of conscious SR to the development of psychological well-being in adolescence. Design Two three-year longitudinal studies were carried out on samples of young adolescents in Russian schools (N = 148; N = 132; 10–13 years). The studies utilized methods for assessing conscious SR, psychological well-being (PWB), and school-related subjective well-being (SWB), the latter being the cognitive component of life satisfaction. Results Our research revealed differences in the dynamics of PWB and SWB levels in adolescents during their transition from primary to basic secondary school. It also identified the specifics of longitudinal relationships between conscious SR, PWB, and SWB in adolescence. We showed that there was a reciprocal relationship between them. However, the most significant cross-longitudinal effects were established between SR and school-related SWB. These effects changed over time: at the beginning, well-being acted as a significant factor of self-regulation, while later self-regulation acted as a significant resource for maintaining adolescent well-being in the subsequent years. Conclusion School-related SWB is characterized by the most pronounced trajectory of change, while PWB is characterized by greater stability and insignificant growth. Our three-year longitudinal study demonstrated that the link between self-regulation and well-being is consistently reproduced. Conscious self-regulation is a significant resource for both the psychological and school subjective well-being of adolescents.
