Constructivism Theory: The Factors Affecting Students’ Academic Performance in Higher Education

This paper aimed to use social media impact on student studies in higher education. Apart from enjoyment and academic purposes, many educational practices and processes have been influenced by social networks. This paper highlighted the use of media tools in higher education as well as indicates out some of the factors. Moreover, through a literature review of related articles, we aim to provide insights into the impacts of a social network on educational quality, actual use of social media, and performance impact in higher education. A questionnaire survey on constructivism was circulated among a total of 206 university students as the key method for collecting data. This research hypothesizes educational quality and actual social media use indicates a positive effect in education, all of which also hypothesizes constructivism for educational quality and actual social media that in turn improve students’ satisfaction, and performance impact. Moreover, all research findings were attained through a quantitative method using the Structural Equation Modeling (SEM-AMOS). Findings of this research to indicate a positive effects students on their academic through behavioral intention to utilize social media to actual social media use for teaching and learning on higher education. Moreover, the results mention the use of social media for learning purpose, as well as social media to enables the sharing of knowledge, discussions, and information to enhance students' learning activities, Further studies are recommended which universities educators should take this into consideration when planning their curricula; it comes to the inclusion of technology in the teaching process.
Teachers and Students’ Perception toward Character Education in English Textbooks

This study aimed at investigating how far teachers and students really understand the existence of character education in the curriculum, especially through the teaching and learning process in the classroom by using English textbooks as a medium. There were six teachers and six students who participated in this research. A semi-structured interview with a one-on-one interview was conducted in order to see the perspective of teachers and students about character education in their textbooks. The study revealed that both teachers’ and students’ agreed that character education is essential in creating good individuals with noble characters to tackle moral degradation. Their understanding of character education in the textbooks they were using now was satisfactory. It can be seen through both teachers and students were aware of dealing with character values in the textbooks that embedded in the teaching and learning materials which can be presented both in form of implicit and explicit but they did not know about 18 character values proposed by the government yet.
Internal regulation in compressible turbulent shear layers

Abstract High-resolution simulations of temporally evolving mixing layers, for convective Mach numbers ranging from $M_c=0.2$ to $M_c=2.0$ with density ratios $s=1$ and $s=7$, are analysed to characterize compressibility effects on the structure and evolution of turbulence in this compressible flow. Published experimental results are used to validate simulation results. Examination of the turbulence scales in the present data suggests an internal regulation mechanism. Correlated eddying motions were found to be in support of a ‘sonic eddy hypothesis’. Eddy scales in all spatial directions are found to be a progressively smaller fraction of the overall mixing-layer thickness with increasing $M_c$, forming independent layers of eddying motions at high $M_c$. These reduced spatial scales serve to reduce the effective velocity scale for turbulent motions, suppressed Reynolds stresses, turbulent kinetic energy (TKE) production and dissipation, and the mixing-layer thickness growth rate.
Development of Liquid Membrane Pertraction for the Removal and Recovery of Chromium from Aqueous Effluents

Abstract Liquid membrane pertraction combines the loading and stripping steps of solvent extraction into a single unit operation, allowing the continuous removal and concentration of a given species. In this paper the feasibility of applying liquid membrane pertraction to the recovery of chromium (Cr(VI) from aqueous effluents with the objective of reducing levels to below allowable discharge limits has been examined. A continuous laboratory-scale liquid membrane pertractor was constructed to solve a variety of problems associated with the treatment of Cr(VI)-bearing streams. Various operational factors such as feed velocity, strip velocity, membrane velocity, and composition of the inlet feed were then examined. Satisfactory continuous runs lasting up to 22 days were achieved. Chromium levels in synthetic waste could be reduced from 200–300 mg/L down to 1 mg/L, well within most allowable discharge limits. Experiments showed that the strip phase can be concentrated with inlet Cr(VI) concentrations of 2000.
Comparing the Ability and Accuracy of mSOFA, qSOFA, and qSOFA-65 in Predicting the Status of Nontraumatic Patients Referred to a Hospital Emergency Department: A Prospective Study

Abstract Introduction This study was proposed to compare the ability and accuracy of modified sequential organ failure assessment (mSOFA), quick SOFA (qSOFA), and qSOFA-65 in predicting the status of nontraumatic patients referred to hospital emergency departments (EDs). Materials and methods This study was a prospective design that performed on the 746 nontraumatic patients referred to the ED. Each patient data was collected using a demographic questionnaire, mSOFA, qSOFA, and qSOFA-65 scales. Related variables of each scale were recorded based on patients’ medical records. Then, the outcome of each patient in the ED was followed up and recorded. The severity and specificity of each scale were estimated by the area under receiver operating characteristic (AUROC) curve at 99% confidence interval (CI). Results The mean and standard deviation of scores were as follows: mSOFA = 4.40 ± 2.58, qSOFA = 0.50 ± 0.70, and qSOFA-65 = 0.92 ± 0.96. Patients requiring admission to the intensive care unit (ICU) were identified with AUROC curve as follows: mSOFA = 0.882 (99% CI = 0.778–0.865); qSOFA = 0.717 (99% CI = 0.662–0.773); and qSOFA-65 = 0.771 (99% CI = 0.721–0.820), which showed that mSOFA has higher sensitivity and specificity than the other two scales in identifying patients requiring admission to the ICU. Conclusion All three scales were found to be reliable for identifying nontraumatic patients at risk of death and patients requiring admission to the ICU. However, since the time and data required to complete qSOFA and qSOFA-65 are much less than those of mSOFA, it is recommended that qSOFA and especially qSOFA-65 be used in ED to identify critically ill nontraumatic patients.

On-Line HP(LC)-GC-FID Determination of Hydrocarbon Contaminants in Fresh and Packaged Fish and Fish Products.

BACKGROUND Fish products can be contaminated with mineral oil hydrocarbons (MOH), mainly as a result of environmental contamination (wild fish) or contaminated feeds (farmed fish). Packaged products may also be contaminated with polyolefin oligomeric hydrocarbons (POH), which, depending on the packaging, storage condition, matrix composition, and fat content, may migrate relatively easily from the packaging to the food. OBJECTIVE A rapid, solvent-sparing method for determining hydrocarbon contaminants in fish products was developed, validated, and applied to farmed and wild fish products (both fresh and packaged samples, stored under different conditions). METHOD Microwave-assisted saponification (MAS) was used in combination with on-line LC-GC-flame ionization detection (FID). RESULTS The proposed method showed quantitative recovery, good repeatability, and high sensitivity. Farmed salmon had variable mineral oil saturated hydrocarbon contamination (from 0.5 to 4.3 mg/kg), accompanied by mineral oil aromatic hydrocarbons (maximum 1.4 mg/kg), while wild salmons had no detectable contamination. Samples of one farmed salmon and a swordfish, both sliced and packed under vacuum, resulted contaminated with POH migrated from the packaging. POH migration was also evident in a ready-to-eat meal. CONCLUSIONS The proposed method showed good performance characteristics in terms of recovery, repeatability, and LOQ. Fatty fish products are more prone to contamination with hydrocarbon contaminants. HIGHLIGHTS MAS allows for rapid and efficient sample preparation. An LC-GC-FID method for MOH/POH determination in fish products was validated. Fish products may be contaminated with variable amounts of hydrocarbon contaminants.
Ethnic enclaves and self-employment among Middle Eastern immigrants in Sweden: ethnic capital or enclave size?

ABSTRACT We employ geocoded data to explore the effects of ethnic enclaves in Swedish cities on the propensity of Middle Eastern immigrants to transcend from having no employment to self-employment. We demonstrate a robust tendency for immigrants to leave non-employment for self-employment if many co-ethnic peers in the enclave are business owners, while we observe weak effects emanating from business owners in other groups. Net of these effects, overall enclave size, measured by the local concentration of co-ethnic peers, has a negative influence on the propensity for a non-employed immigrant to become self-employed.
Stalagmite carbon isotopes suggest deglacial increase in soil respiration in Western Europe driven by temperature change

Abstract. The temperate region of Western Europe underwent dramatic climatic and environmental change during the last deglaciation. Much of what is known about the terrestrial ecosystem response to deglacial warming stems from pollen preserved in sediment sequences, providing information on vegetation composition. Other ecosystem processes, such as soil respiration, remain poorly constrained over past climatic transitions, but are critical for understanding the global carbon cycle and its response to ongoing anthropogenic warming. Here we show that speleothem carbon isotope (δ13Cspel) records may retain information on local soil respiration, and allow its reconstruction over time. While this notion has been proposed in the past, our study is the first to rigorously test it, using a combination of multi-proxy geochemical analysis (δ13C, Ca isotopes, and radiocarbon) on three speleothems from Northern Spain, and quantitative forward modelling of processes in soil, karst, and cave. Our study is the first to quantify and remove the effects of prior calcite precipitation (PCP, using Ca isotopes) and bedrock dissolution (using the radiocarbon reservoir effect) from the δ13Cspel signal to derive changes in respired δ13C. Coupling of soil gas pCO2 and δ13C via a mixing line describing diffusive gas transport between an atmospheric and a respired end member allows modelling of changes in soil respiration in response to temperature. Using this coupling and a range of other parameters describing carbonate dissolution and cave atmospheric conditions, we generate large simulation ensembles from which the results most closely matching the measured speleothem data are selected. Our results robustly show that an increase in soil pCO2 (and thus respiration) is needed to explain the observed deglacial trend in δ13Cspel. However, the Q10 (temperature sensitivity) derived from the model results is higher than current measurements, suggesting that part of the signal may be related to a change in the composition of the soil respired δ13C, likely from changing substrate through increasing contribution from vegetation biomass with the onset of the Holocene.
TWO ARGUMENTS AGAINST THE GENERIC MULTIVERSE

Abstract This paper critically examines two arguments against the generic multiverse, both of which are due to W. Hugh Woodin. Versions of the first argument have appeared a number of times in print, while the second argument is relatively novel. We shall investigate these arguments through the lens of two different attitudes one may take toward the methodology and metaphysics of set theory; and we shall observe that the impact of these arguments depends significantly on which of these attitudes is upheld. Our examination of the second argument involves the development of a new (inner) model for Steel’s multiverse theory, which is delivered in the Appendix.
Branch prunning and chicken manure application to improve growth and yield of brocolli in lowland area

The objective of this study was to determine the effect of branch pruning and chicken manure application on improving the growth and yield of broccoli in the lowland. The research was conducted in the dry land of Kutasari Village, Baturraden District, Banyumas Regency at 138 m above sea level. The research was arranged in a Factorial Randomized Complete Block Design (RCBD) with three replications consisting of two factors of chicken manure application (without chicken manure and with chicken manure at doses of 10 ton.ha -1 and 20 ton.ha -1 ) and branch pruning (without and with branch pruning of 25% and 50%). The pruning was performed when the plants initiated flowers. The observed data were analyzed with the F test and followed with Duncan's Multiple Range Test (DMRT) at a P >0.05. The branch pruning resulted in a significant effect on the number of leaves, leaf width, head weight, and head diameter. Meanwhile, the chicken manure application showed a significant effect on all of the observed variables. There was an interaction effect of branch pruning and chicken manure application on the leaf width, head weight, and head diameter. The best result was obtained by the combined treatment of 50% branch pruning and 20 ton.ha -1 chicken manure, resulting in the head weight of 1048.33 g.plant -1 and leaf width of 1705.41 cm 2 .

Predictors of professional quality of life among nurses–A cross sectional study

A good practice environment is a vital aspect of the staffing and retention of health care workers, especially of nurses affecting patient care. This study investigates the predictors of nurses’ Professional Quality of Life working in public hospitals and private hospitals. A cross-sectional design was utilized, including 374 nurses conveniently sampling selected in two public hospitals and two private hospitals in the Philippines using a Practice Environment Scale of the Nursing Work Index and Professional Quality of Life scale having a good psychometric property, respectively. The overall mean score for practice environment for Nurses is at a low level, whereas the mean Professional Quality of Life score was at a moderate level. Age is significantly associated with the burnout subscale (r=-0.119, p<0.021) and with secondary traumatic stress (r=-0.193, p<0.001). Monthly salary is significantly associated with the compassion satisfaction subscale (r=-0.140, p=0.007) and STS (r=0.107, p=0.038). Meanwhile, the working hours' figure is significantly associated with compassion satisfaction subscale (r=-0.133, p=0.010). Finally, the practice environment of nurses shown is significantly associated with compassion satisfaction subscale (r=-0.426, p=0.007) and secondary traumatic stress (r=0.524, p<0.001). Filipino nurses have a lower practice environment and moderate professional quality of life. The predictors of the professional quality of life of nurses were age, monthly salary, working hours, and their practice environment. Specifically, the higher the salary and the shorter the working hours, the better their professional quality of life. Additionally, the poorer the practice environment, the lower the professional quality of life.
Redistribution of particulate organic matter during ultrasonic dispersion of highly weathered soils

The use of ultrasonic energy for the dispersion of aggregates in studies of soil organic matter (SOM) fractionation entails a risk of redistribution of particulate organic matter (POM) to smaller particle‐size fractions. As the mechanical strength of straw also decreases with increasing state of decomposition, it can be expected that not all POM will be redistributed to the same extent during such dispersion. Therefore, we studied the redistribution of POM during ultrasonic dispersion and fractionation as a function of (i) dispersion energy applied and (ii) its state of decomposition. Three soils were dispersed at different ultrasonic energies (750, 1500 and 2250 J g−1 soil) or with sodium carbonate and were fractionated by particle size. Fraction yields were compared with those obtained with a standard particle‐size analysis. Undecomposed or incubated (for 2, 4 or 6 months) 13C‐enriched wheat straw was added to the POM fraction (0.25–2 mm) of one of the soils before dispersion and fractionation. Dispersion with sodium carbonate resulted in the weakest dispersion and affected the chemical properties of the fractions obtained through its high pH and the introduction of carbonate. The mildest ultrasonic dispersion treatment (750 J g−1) did not result in adequate soil dispersion as too much clay was still recovered in the larger fractions. Ultrasonic dispersion at 1500 J g−1 soil obtained a nearly complete dispersion down to the clay level (0.002 mm), and it did not have a significant effect on the total amount of carbon and nitrogen in the POM fractions. The 2250 J g−1 treatment was too destructive for the POM fractions since it redistributed up to 31 and 37%, respectively, of the total amount of carbon and nitrogen in these POM fractions to smaller particle‐size fractions. The amount of 13C‐enriched wheat straw that was redistributed to smaller particle‐size fractions during ultrasonic dispersion at 1500 J g−1 increased with increasing incubation time of this straw. Straw particles incubated for 6 months were completely transferred to smaller particle‐size fractions. Therefore, ultrasonic dispersion resulted in fractionation of POM, leaving only the less decomposed particles in this fraction. The amounts of carbon and nitrogen transferred to the silt and clay fractions were, however, negligible compared with the total amounts of carbon and nitrogen in these fractions. It is concluded that ultrasonic dispersion seriously affects the amount and properties of POM fractions. However, it is still considered as an acceptable and appropriate method for the isolation and study of SOM associated with silt and clay fractions.
Eco-Design of Airport Buildings and Customer Responses and Behaviors: Uncovering the Role of Biospheric Value, Reputation, and Subjective Well-Being

This research was an empirical effort to uncover the influence of eco-design of airport buildings on customer approach responses and behaviors. A survey methodology with empirical data analysis was used to attain the research purpose. Our findings revealed that eco-design contributes to enhancing airport reputation and airport customers’ subjective well-being. In addition, eco-design, reputation, and well-being directly/indirectly increase customer approach intentions. Our result also indicated that the association between eco-design and airport reputation is under the significant influence of biospheric value. Moreover, airport reputation and subjective well-being mediated the effect of eco-design on intentions. The comparative importance of airport reputation in determining approach intentions was identified. Overall, the proposed theoretical framework satisfactorily accounted for approach intentions. Given the lack of knowledge about eco-design in the airport literature, this research help boosts airport researchers’ and practitioners’ understanding of the role of eco-design and its criticality in explicating approach formation and behaviors.
Cyclophosphamide Loaded Albumin Microspheres: Liver Entrapment and Fate in Mice

AbstractMicrospheres offer the possibility of target selectivity through choice of appropriate size or surface charecteristics, slow release of drug and also minimize systemic toxicity. The active substance of this investigation, cyclophosphamide (CP), interferes with the growth of cancer cells which are eventually destroyed. Since side effects of CP are frequently dose related, by incorporating low dose of CP to human serum albumin (HSA) microspheres, the normal body cells are not affected while the tumour cells are destroyed.Cyclophosphamide microspheres were prepared by the modification of the method of Scheffel et al and Gurkan et al. 2,3-butanedione was used as a cross-linking agent. The albumin microspheres containing CP were labelled by 99mTc by incorporating SnC12.2H20 at a concentration of 5% of the matrix material. All the microspheres used in this study ranged between 1–5 μm. A suspension of 99mTc labelled cyclophosphamide microspheres was injected into swiss albino mice intravenously. At 15 min.
Social Impact Assessment of HealthyAIR Tool for Real-Time Detection of Pollution Risk

Background: HealthyAIR is a tool that detects pollution risk in real life. The target population is people with cardiorespiratory complications who are especially susceptible to the current COVID-19. The goal is to empower people by controlling air pollution everywhere to minimize the risk of having a seizure. Methods: We measured the social impact of the HealthyAIR tool using a Likert scale survey with two groups: professionals (engineers/healthcare) and end-users. We assessed the data in accordance with the indicators for social impact defined for the Key Impact Pathways introduced by the European Commission for Horizon Europe, and the criteria of the Social Impact Open Repository (SIOR). Results: Professionals highlight the fact that they “totally agree” (33.33%) and “agree” (26.67%) that HealthyAIR could help authorities improve their health prevention policies and programs. Users considered the tool to be “very useful” (38.46%) and “quite useful” (42.31%), which denotes its necessity. Conclusions: professionals and end users see HealthyAIR as a great preventative tool, with the former seeing it as a way to avoid seizures in their patients who, in this COVID-19 era, are particularly sensitive to any cardiorespiratory health problem. However, users suggest improving the user’s manual to make it more understandable.
