Dependability of College Student Ratings of Teaching and Learning Quality

The U.S. Commission on the Future of Higher Education (2006) has expressed concerns about the quality of higher education. As a response to accountability demands, such as those of the Commission, several institutional-level assessment efforts have been undertaken, such as administration of standardized tests and surveys of student engagement. Nonetheless, universities and colleges have often used student ratings as a means of evaluating courses and instruction— because they are very practical. According to meta-analyses, only a few items on typical course evaluations have been found to be related to student achievement. To address these concerns, Frick, Chadha, Watson, Wang and Green (2009) developed a new course evaluation instrument that consists of nine student rating scales of teaching and learning quality (TALQ). Five TALQ scales measure First Principles of Instruction, which were derived from a synthesis of instructional theories by Merrill (2002; 2009). Other TALQ scales measure student perceptions of successful engagement (academic learning time) and learning progress. The present study examined the dependability of TALQ scale scores, since these psychometric properties have not been previously addressed. The TALQ was administered near the end of the semester to 464 students in 12 classes taught by 8 professors at a large Midwestern university. Results of generalizability studies revealed that TALQ scale scores were dependable for student ratings of overall course and instructor quality, satisfaction, learning progress and on 3 First Principles of Instruction (activation, application and integration). Two of the First Principles scale scores were found to be less dependable (authentic problems and instructor demonstration), as well as student academic learning time. Based on these findings, changes in 3 items are suggested. Changes in 5 items on the academic learning time scale are also recommended. Future validation studies are Dependability of College Student Ratings of TALQ – 3 recommended that investigate the use of the modified TALQ scales for improving the quality of teaching in postsecondary education.
Evidence that pubertal status impacts kisspeptin/neurokinin B/dynorphin neurons in the gilt

Abstract Puberty onset is a complex physiological process, which enables the capacity for reproduction through increased gonadotropin-releasing hormone and subsequently luteinizing hormone secretion. While cells that coexpress kisspeptin, neurokinin B (NKB), and dynorphin in the hypothalamic arcuate nucleus are believed to govern the timing of puberty, the degree to which kisspeptin/NKB/dynorphin (KNDy) neurons exist and are regulated by pubertal status remains to be determined in the gilt. Hypothalamic tissue from prepubertal and postpubertal, early follicular phase gilts was used to determine the expression of kisspeptin, NKB, and dynorphin within the arcuate nucleus. Fluorescent in situ hybridization revealed that the majority (>74%) of arcuate nucleus neurons that express mRNA for kisspeptin coexpressed mRNA for NKB and dynorphin. There were fewer arcuate nucleus cells that expressed mRNA for dynorphin in postpubertal gilts compared to prepubertal gilts (P < 0.05), but the number of arcuate nucleus cells expressing mRNA for kisspeptin or NKB was not different between groups. Within KNDy neurons, mRNA abundance for kisspeptin, NKB, and dynorphin of postpubertal gilts was the same as, less than, and greater than, respectively, prepubertal gilts. Immunostaining for kisspeptin did not differ between prepubertal and postpubertal gilts, but there were fewer NKB immunoreactive fibers in postpubertal gilts compared to prepubertal gilts (P < 0.05). Together, these data reveal novel information about KNDy neurons in gilts and support the idea that NKB and dynorphin play a role in puberty onset in the female pig. Summary sentence The degree to which KNDy neurons exist in the gilt is characterized for the first time, and the impact of pubertal status on kisspeptin, neurokinin B, and dynorphin in the arcuate nucleus of gilts is examined. Graphical Abstract
Study of Three Dimensional Fluid Flow in Manifold-Laterals System

A three dimensional numerical simulation of fluid flow in a manifold-laterals system was carried out; several geometrical changes were made to study the effect on water flowing inside the manifold. The manifold hydraulic diameter and the length were kept constant in the study. The geometrical changes include the distance between laterals, the length of the laterals, and the laterals size. It is found that for Reynolds Number (100 and 1000), increasing the length of the laterals gives uniform flow profile at laterals outlet. Also reducing lateral size will create a similar effect. A good agreement was found between the present and FLUENT6.2 results for mass flow rate from laterals.
Evolutionary Game Theoretic Approach to Rear-End Events on Congested Freeway

Rear-end crashes on freeways contribute significantly to nonrecurring congestion. Reducing these events would significantly improve freeway capacity, particularly during peak hours. Although promising countermeasures, such as variable speed limits, changeable message signs, and vehicle-based improvements, are under consideration, currently there is a shortage of demonstrably proven countermeasures targeted at freeway rear-end crashes. Liability rules, in which the direct cost associated with a crash is divided between the drivers, their insurance companies, or both, are a primary mechanism for influencing the occurrence of freeway rear-end crashes. An exploratory effort uses concepts from evolutionary game theory to predict the effects of liability rules on rear-end crashes. In a typical two-vehicle car-following scenario, driving behavior can be associated with a utility that each driver expects to achieve depending on his or her and the opponent's actions. Such interactions between leader and follower are modeled as the outcome of an evolutionary process in which drivers with different driving behaviors are randomly and repeatedly matched against each other to play a two-player game. The outcome of these games determines the fraction of drivers pursuing a particular driving strategy for the next phase of the game. The stable long-run distribution of driving strategies is then used to predict the proportion of drivers who are more likely to be involved in a rear-end accident. It turns out that when direct crash costs are allocated evenly to the involved drivers, a population in which all drivers act to avoid crashes is not evolutionarily stable.
Evaluation of surgical outcomes of 23-G versus 25-G vitrectomy for pediatric retinal detachment

Objective To compare surgical and clinical outcomes of pediatric retinal detachment repair using 23 G and 25 G vitrectomy. Background The introduction of microincisional vitrectomy surgery induced a paradigm shift in management of vitreoretinal diseases. Vitrectomy in pediatric age group represents a major challenge owing to its unique anatomical and pathological considerations. Patients and methods This was a prospective, comparative case series study. A total of 50 patients were recruited for the study and divided into two groups. The first group included 25 patients who underwent 23-G vitrectomy, and the second group included 25 patients who underwent 25-G vitrectomy. The main outcome measures were the actual vitrectomy time and need to suture a sclerotomy and the early postoperative hypotony rate. Results The actual time for vitreous removal was 22.00 ± 5.71 min in 23-G group compared with 24.13 ± 5.97 min in 25 G group (P = 0.273). A significant difference was noted between both groups regarding suturing at least one sclerotomy at the end of the surgery, with 11 (44%) eyes in 23-G group and only four (16%) eyes in 25-G group; however, no significant difference in early postoperative hypotony rate was observed. The visual and anatomical outcomes were comparable between both groups, with no significant difference. Conclusion Both 23-G and 25-G systems are highly efficient for the treatment of pediatric retinal detachment. However, our research showed that operations performed with the 25-G system were less likely to demand a suture with earlier visual recovery.
SEED MACRO- AND MICRO-MORPHOLOGY OF SOME SPECIES OF KICKXIA DUMORT, SCROPHULARIA L. AND PLANTAGO L. FROM SAUDI ARABIA

The seed macroand micro-morphological characters of 13 species belonging to three genera; Kickxia Dumort, Scrophularia L. and Plantago L. , collected from different localities of Saudi Arabia, were studied using a Stereomicroscope and Scanning Electron Microscope for evaluating their taxonomic relationships. Three macro-morphological characters of seeds were shape, size, and color while three diagnostic micromorphological characters were seed coat sculpture, the anticlinal and periclinal wall. , The seed shape seems to be specific in Plantago L. (peltate, angled) than the two other genera while the color and seed size show little importance. The Plantago L. has a specific rugose sculpture while the other two genera have either tuberculate or alveolate. So Plantago L. was possessed no affinities to Kickxia Dumor or Scrophularia L. This observation gives extra support to the earlier taxonomic views that suggested the retention of two genera in the traditional family Scrophulariaceae and maintaining Plantago L. in a separate monogeneric family Plantaginaceae Detailed analysis of seed characters of more species is needed to clarify the systematic relationships between the three genera. A key to the identification of studied species based on seed microand macro-morphological characters is provide. Introduction Scrophulariaceae is a large worldwide family (Miranda, 1988), with approximately 222 genera and 4480 species (Willis, 1973), mostly found in temperate zones of the northern hemisphere (Heywood, 1985). The Kickxia Dumort (Scrophulariaceae) is one of the most important genera, with roughly 47 species (Mabberley, 1997). The genus is represented in Saudi Arabia by 10 species (Chaudhary, 2001), the majority of which are found in the south and west of the country. Scrophularia L. (Scrophulariaceae) is another major genus with over 300 species represented in both the ancient and modern worlds (Lersten and Curtis, 1997). It is represented by four species in Saudi Arabia (Chaudhary, 2001). Since ancient times, many species of this genus have been utilized as traditional medicine. The Plantaginaceae is a worldwide family of three genera: Plantago, Littorella, and Bougueria, which grow in a variety of environments (Bentham, 1846; Wettstein, 1891; Dahlgren, 1975; Cronquist, 1981; Heywood, 1993; Takhtajan, 1997). Plantago L. (Plantaginaceae) is a perennial herb with a rosette of leaves at the base of the plant (Chiang et al., 2002). The herb can be used to treat a variety of ailments. It is used to treat hypercholesterolemia and lower blood sugar levels (Haddadian et al., 2014). It is also used to treat cancer (Souri et al., 2008; Pourmorad et al., 2006). It is represented by at least 12 species in Saudi *Corresponding author, Email: lm.al-masoudi@tu.edu. sa Department of Botany and Microbiology, Faculty of Science, King Saud University, Riyadh, Saudi Arabia.

A Comparative Study of Flows Through Funnel-Shaped Bottlenecks Placed in the Middle and Corner

Upon exiting buildings, theatres, and stadiums, which house a great number of people, egress points can act as bottlenecks, resulting in crowded exits and decreased flows. Most studies investigating flow have been conducted in either narrow bottlenecks (doors) or funnel shape bottlenecks, with the latter investigating bottlenecks placed in the middle of the walkway. This study investigates, for the first time, crowd flow through funnel-shaped bottlenecks placed in the corner of the walkway and makes comparisons with similar bottlenecks of the same length, entrance and exit width placed in the middle of the walkway. The entry width and exit width of the bottlenecks were 3 m and 1 m respectively, with lengths varying from 1 m to 4 m; they continued into a 10 m corridor. Ninety-four participants of various ages were observed moving through each of the configurations. The results indicated that using funnel-shaped bottlenecks in the middle of the walkway increased the flow rate significantly compared to the corner in bottlenecks with 2 m and 3 m lengths. This is contrary to what some other researchers have found for narrow bottlenecks placed in the middle and corner of a wall, although it is recognised that the configuration of funnel-shaped bottlenecks makes the comparison more complex and further work is required in this area. Notwithstanding these results are considered valuable for consideration when designing egress points and corridors in complex buildings such as metro and train stations.
Can Transvaginal Sonography Promotes Management of Pregnancy of Unknown Location (PUL) and Reduces Number of βHCG test?

Pregnancy of Unknown Location (PUL), is defined when a pregnancy test is positive but there is no sign of intra or extra uterine pregnancy or retained products of conception (RPOC), visualized by transvaginal ultrasonography (TVS). PUL occurs in up to 30% of initial early pregnancy scans [1,2]. Many women classified as having PUL usually present with lower abdominal discomfort/pain or vaginal bleeding.
THE IMPACT OF COVID-19 PANDEMIC ON CREDIT FINANCING OF MICROENTERPRISES ..

The novel coronavirus pandemic has hit the Polish economy, including business activity. The paper aims to assess the impact of COVID-19 on the credit financing of microenterprises and farmers in Poland. We analyse investment loans and working capital loans, particularly the changes in the number and value of these loans, the number of loan enquiries, and the share of non-performing loans. The research period covers the two-year period, including the pre-COVID-19 subperiod from March 2019 till February 2020 and the COVID-19 subperiod from March 2020 till February 2021. We obtain monthly data from BIK. The BIK Group is the main source of credit and economic information in Poland. The study reveals a significant decrease in the number and value of investment loans and working capital loans during the COVID-19 period compared to the pre-COVID-19 period both in groups of microenterprises and farmers. Surprisingly, despite the difficult time for entrepreneurs, the COVID-19 pandemic significantly reduced the number of loans enquiries. As we expected, the number and value of non-performing loans increase due to the COVID-19 pandemic. However, the value of non-performing investment loans in the group of microenterprises increased marginally.Our research can be helpful for decision-makers and credit market participants, including national governments, financial market supervisory institutions, banks, and micro-entrepreneurs, and farmers.
Hollow Fiber Membrane Modules for NOx Removal using a Mixture of NaClO3 and NaOH Solutions as Absorbents

Nitrogen oxide (NOx) is one of the polluting gases harmful to humans and the environment. Nitrous oxide gas is mostly found in air, namely nitrogen monoxide (NO) and nitrogen dioxide (NO2). NOx gas in the air, which mostly comes from exhaust gases, needs to be reduced to minimize the hazards to humans and the environment and comply with applicable regulations regarding hazards. The absorption process with a membrane contactor is an alternative to reduce NOx concentrations in the air. This study evaluates the hollow fiber membrane modules' performance in the NOx absorption process using sodium chlorate (NaClO3) and sodium hydroxide (NaOH) as an absorbent solution. Based on the experimental results, the NOx reduction efficiency increased with an increase in the absorbent concentration and the amount of fibers in the membrane module but declined with an increase in the feed gas flow rate. The highest value of NOx reduction efficiency, the overall mass transfer coefficient, the flux, and the NOx loading obtained in the study were 99.7%, 0.01743 cm s-1, 9.510 x 10-8 mmole cm-2 s-1, and 0.026 mole NOx/mole NaClO3, respectively.

An empirical test of the role of status-quo bias in energy-related individual choices

The status-quo bias is a behavioral bias that may increase the energy consumption of a household through at least three channels: (1) by making consumers keep their energy-using durables as long as possible, until wearout forces them to replace their equipment (2) by making consumers choose new energy-using durables that resemble the existent ones that need replacement, and (3) by making consumers overuse appliances in an attempt to mentally amortize the initial investment cost. The results presented in this study are a first attempt to empirically investigate whether the presence of bias towards the status quo plays a role in individuals energy-related decision making. Using data from a large household survey conducted in three European countries (Switzerland, the Netherlands and Italy), we find that our measure of status-quo bias is a significant predictor of both the age of home appliances as well as the level of consumption of energy services of a household. The tendency of status-quo biased individuals to keep their current appliances longer and to use their appliances more is also reflected in the total electricity consumption of the households, which is found to be around 5.7% higher than the consumption of households in which the household head is not status-quo biased. The status-quo bias thus has the potential to create a substantial barrier to reaching the energy-efficiency targets of the European Union. These findings prompt policy makers to design policy instruments that take this barrier into account.
The impact of grants in combination with school-based management trainings on primary education: a cluster-randomized trial in Northern Nigeria

ABSTRACT Grant disbursals and school-based management interventions have received growing attention from policy-makers despite their mixed success at improving educational outcomes. This paper reports results from a large-scale, cluster randomised controlled trial in Sokoto state, Nigeria. School-based management committees received a training and a grant to improve access to and quality of primary school education, especially for girls. One year after implementation, the intervention had no impact on schools’ infrastructure, educational attainment or learning outcomes . Therefore, understanding the context-specific constraints to primary school education is important to avoid spending 100 million USD on a programmewith no discernible impact.
Nonlinear modelling of the PWM switch

It is shown that nonlinearity due to the switching action in pulse width-modulated (PWM) DC-to-DC converters, DC-to-AC inverters or amplifiers, and input-current-shaping DC-to-DC converters can often conveniently be confined to a three-terminal structure referred to as the PWM switch. the PWM switch represents a static nonlinearity for which circuit models can easily be derived for frequencies harmonically related to the frequency of perturbation. Converter analysis can now be approached in an analogous way to ordinary transistor circuit analysis whereby the nonlinear three-terminal device is replaced by its circuit model. A first-order approximation of the model results in the small-signal model. <<ETX>>
The Relationship between Learning Vocabulary via Mobile (Mobile-Assisted Language Learning) and Iranian EFL Learners’ Social Anxiety and Loneliness

The present study has investigated the relationship between learning English vocabulary via mobile phone and the learners’ social anxiety and loneliness. The participants of the study were thirty-two intermediate English as foreign language (EFL) learners studying English at the University of Zanjan, Zanjan, Iran. Sixty American English idioms were chosen and became available in a Telegram channel, during a six-week period of treatment to provide the participants with Mobile-Assisted Language Learning (MALL). A researcher-designed achievement test was administered to assess the learners’ vocabulary learning via mobile phone. Interaction Anxiousness Scale (IAS) (Leary 1983) and UCLA Loneliness Scale version 3 (ULS) (Russell 1996) were used to estimate the learners’ social anxiety and loneliness, respectively. The results showed no significant correlation between the variables; thus, it can be concluded that MALL not only frees the learners from the restrictions of time and place, but also minimizes the possible intervention of some socially and emotionally affective variables, such as social anxiety and loneliness in the process of language learning. Keywords: Learning Vocabulary, Mobile-assisted Language Learning, Social Anxiety, Loneliness
