Conceptualisation of students’ school-related wellbeing: students’ and teachers’ perspectives

ABSTRACT Background Converging evidence points to the relevance of adolescent wellbeing as a resource for positive development and successful learning. As schools represent one of the most significant environments for adolescent development, there is increasing interest in students’ wellbeing in schools. However, the growing body of research reveals great heterogeneity regarding operationalisations of school-related wellbeing. Purpose The present study aims to contribute to the conceptualisation of the construct by taking a closer look at experiences within the context. In doing so, it takes a multi-informant approach and explores students’ and teachers’ perspectives. Method A survey was conducted among secondary school students (n = 150) and teachers (n = 197). Participants provided responses to open-ended questions, addressing their general understanding of the construct and indicators of high and low levels of school-related wellbeing. Data were analysed using a qualitative content analysis approach. The EPOCH model of Kern et al., with the dimensions Engagement, Perseverance, Optimism, Connectedness and Happiness, was applied as a categorisation framework. For coded segments that did not correspond to the EPOCH domains, the category system was expanded inductively. Findings Just over three quarters of all coded segments referred to the EPOCH domains. Three categories were inductively added: Physical health, Achievement and Framework conditions. Overall, in terms of the content addressed as well as frequencies of the themes, there was a degree of homogeneity across the responses of students and teachers, although findings suggested greater emphasis on eudaimonic aspects in the teacher sample. Conclusions The present study provides initial insights into students’ and teachers’ perspectives regarding the conceptualisation of school-related wellbeing and supports the approach of conceptualising it both in terms of hedonic and eudaimonic aspects. It supports the application of the EPOCH model to the school context, considers additional detailed aspects and underscores the multidimensionality of the construct. Future research is required to investigate the roles of all identified categories and whether they correspond to a statistical measurement model.
Outcome of total hip and knee arthroplasty in HIV-infected patients: A systematic review

Significant advances in the treatment of Human Immunodeficiency Virus (HIV) have occurred in recent times, with life expectancy now approaching the normal population. Therefore, patients with HIV will increasingly be undergoing joint replacement in the future, however concerns remain regarding the complications and outcome in this patient cohort. The aim was to assess the outcome of total hip and knee arthroplasty in HIV-infected patients. A systematic search of the literature using MOOSE reporting guidelines was performed to assess the outcome of hip and knee arthroplasty in HIV-infected patients. The primary outcome was infection. Secondary outcome was all-cause revision. The search yielded 552 results, of which 19 met the inclusion criteria, comprising 5.819. 412 joint replacements. The overall quality of the studies was poor with significant heterogeneity between the studies. Infection and revision appeared to be more likely to occur in HIV positive patients compared to HIV negative patients. A subgroup analysis of four studies revealed a risk ratio of 3.31 and 2.25 for increase in infection and revision respectively in HIV positive patients. This systematic review and meta-analysis demonstrates an increased risk of infection and revision in HIV infected patients undergoing total hip and knee arthroplasty. However, these findings are based on poor quality evidence in a limited number of studies and need to be interpreted with caution. Further research should concentrate on large, well-designed, prospective studies, that control for co-morbidities and employ standardised outcome measures to allow for direct comparison.
Calcium-Dependent Ion Channels and the Regulation of Arteriolar Myogenic Tone

Arterioles in the peripheral microcirculation regulate blood flow to and within tissues and organs, control capillary blood pressure and microvascular fluid exchange, govern peripheral vascular resistance, and contribute to the regulation of blood pressure. These important microvessels display pressure-dependent myogenic tone, the steady state level of contractile activity of vascular smooth muscle cells (VSMCs) that sets resting arteriolar internal diameter such that arterioles can both dilate and constrict to meet the blood flow and pressure needs of the tissues and organs that they perfuse. This perspective will focus on the Ca2+-dependent ion channels in the plasma and endoplasmic reticulum membranes of arteriolar VSMCs and endothelial cells (ECs) that regulate arteriolar tone. In VSMCs, Ca2+-dependent negative feedback regulation of myogenic tone is mediated by Ca2+-activated K+ (BKCa) channels and also Ca2+-dependent inactivation of voltage-gated Ca2+ channels (VGCC). Transient receptor potential subfamily M, member 4 channels (TRPM4); Ca2+-activated Cl− channels (CaCCs; TMEM16A/ANO1), Ca2+-dependent inhibition of voltage-gated K+ (KV) and ATP-sensitive K+ (KATP) channels; and Ca2+-induced-Ca2+ release through inositol 1,4,5-trisphosphate receptors (IP3Rs) participate in Ca2+-dependent positive-feedback regulation of myogenic tone. Calcium release from VSMC ryanodine receptors (RyRs) provide negative-feedback through Ca2+-spark-mediated control of BKCa channel activity, or positive-feedback regulation in cooperation with IP3Rs or CaCCs. In some arterioles, VSMC RyRs are silent. In ECs, transient receptor potential vanilloid subfamily, member 4 (TRPV4) channels produce Ca2+ sparklets that activate IP3Rs and intermediate and small conductance Ca2+ activated K+ (IKCa and sKCa) channels causing membrane hyperpolarization that is conducted to overlying VSMCs producing endothelium-dependent hyperpolarization and vasodilation. Endothelial IP3Rs produce Ca2+ pulsars, Ca2+ wavelets, Ca2+ waves and increased global Ca2+ levels activating EC sKCa and IKCa channels and causing Ca2+-dependent production of endothelial vasodilator autacoids such as NO, prostaglandin I2 and epoxides of arachidonic acid that mediate negative-feedback regulation of myogenic tone. Thus, Ca2+-dependent ion channels importantly contribute to many aspects of the regulation of myogenic tone in arterioles in the microcirculation.
Water and economic productivity using different planting and irrigation methods under dry and wet seasons for wheat

ABSTRACT This study aims to evaluate the water and economic productivity of wheat using different planting and irrigation methods under dry and wet seasons. They were carried out in randomized blocks according to the split-plot design with three replications for two growing seasons. The main plots were P1: Conventional flat planting (CFP), P2: Raised-bed planting (RBP); sub-plots were; I0: Rainfed conditions (RFC), I1: Surface irrigation (SI); basin irrigation (BI) and/or furrow irrigation (FI) and I2: drip irrigation (DI). The highest grain yield (4.61 t ha−1) was in the CFP and BI. Irrigation water productivity (IWP) in the CFP and RBP were 1.31 and 1.60 kg m−3, respectively. DI resulted in 1.82 kg m−3 compared to the SI (1.09 kg m−3). The highest net income, 828 $ ha−1, was in the CFP and BI and the second (749 $ ha−1) was in the RBP and FI. Water economic productivity (WEP) was 0.171 $ m−3 in the CFP compared to 0.151 $ m−3 in the RBP. The SI resulted in more WEP (0.164 $ m−3) than DI (0.159 $ m−3). Thus DI and RBP were not feasible in the study region. All data evaluated were much higher in the wet season.
Antibiotic resistance profiling of Uropathogenic Enterobacteriaceae, Casablanca, Morocco

Introduction: the urinary tract infection is a pathology frequents as well in community as at the hospital. In last years, there has been increased the incidence of antibiotic resistance in Uropathogenic Enterobacteriaceae. This development explains the need for periodic regional surveillance of this resistance to antibiotics, which poses a real problem of public health, because it affects several molecules ranging from β-lactam to quinolones. Objective: the aims of this study is to determine the profile of antibiotic resistance of Uropathogenic Enterobacteriaceae isolated from medical analysis laboratories in Casablanca, Morocco. Materials and methods: This is a prospective study that was conducted on patients who visited medical analysis laboratories in Casablanca city, for urinalysis test from 01 January 2017 to 30 December 2018 (a two full years). The culture was performed according to the usual techniques, and the antibiogram was done according to the recommendations of the Antibiogram Committee of the French Society of Microbiology. The statistical analysis was performed using Microsoft Excel (Microsoft 2016). Results: During our study, we reported 18% of urinary tract infections, Sex ratio F/M was 1.79. In addition, Enterobacteriaceae were the most common germs. Of all the strains isolated, we noted a predominance of Escherichia coli with 75.41%) and Klebsiella ssp with 17.05%. In the course of this study period, we observed high rates of resistance to the main classes of antibiotics, and an overall increase between 2017 and 2018 in this resistance to the majority of β-lactam antibiotics, quinolones and aminoglycosides for almost all species of Uropathogenic Enterobacteriaceae. However, amikacin was the most active molecule against the Uropathogenic Enterobacteriaceae strains isolates. Conclusion: The development of resistance of Uropathogenic Enterobacteriaceae to antibiotics is a worrying phenomenon that exposes us to difficulties in the therapeutic management of infections. The current control of antimicrobial resistance is a real emergency and requires the involvement of public awareness before government instructions.
The Impact of Teacher Method of Delivery and the Marshall Hypothesis

Abstract As we approach the 50-year anniversary of the landmark Furman decision, it is of paramount importance to re-examine Justice Thurgood Marshall’s hypotheses. In Justice Marshall’s second hypothesis in his concurring opinion, he suggested “people who were fully informed’ regarding the death penalty “would find the penalty, shocking, unjust and unacceptable” (p. 361). While there has been much empirical testing of this hypothesis, the intent of this study is to add to the existing literature by examining whether different methods of information delivery produce sentiments in opposition to capital punishment. The main research question to be tested is as follows: does exposure to information have more of an impact on opinions if it is given in-person or in online/hybrid formats? Data were collected by an instructor who taught death penalty classes (n = 143) utilizing different teaching modalities. Results suggest that method of course delivery is marginally significantly related to change in opposition towards capital punishment. More specifically, hybrid/online offerings were more likely to result in increased opposition towards the death penalty after taking the class. Furthermore, the analysis also revealed a significant relationship between teaching modality and level of death penalty knowledge at post-test. In light of recent developments in higher education resulting from the COVID-19 pandemic, it is also beneficial to conduct research that has important implications as colleges and universities come to grips with a new normal in distance learning.
Occupant acceptability of eight-hour-long temperature ramps in the summer at low and high humidities

Previous studies have shown that slow rates of temperature change (0.5/sup 0/C/h) from optimal comfort conditions are almost undetectable by occupants from traditional constant temperature conditions. In our previous 4-hr-long tests thermal acceptability remained above 80% when temperature deviations from optimum were 2/sup 0/C or less. Allowing the inside temperature of a building to drift with outside conditions and internal loads has important energy saving and load shifting implications for both new and old buildings, provided the environment remains thermally acceptable to the building's occupants. Occupant responses to temperature drifts during an 8 1/2-hr working day are reported. Since the energy and cost savings potential of temperature drifting appears to be largest during the summer, clothing and drift conditions appropriate for this season were chosen for these tests. Experiments were conducted where the temperature rose slowly throughout the day from a cool initial condition. Using a similar strategy, a building could be cooled at night with outside air and refrigeration when the air is cooler and when electrical demand and rates are lower and COP's are higher. Then during the day, the building's temperature could be allowed to drift upward with reduced refrigeration or without refrigeration. Many variations of thismore » theme are possible such as using stored chilled, water, increased building mass, and/or a temperature ramp control system. « less
Real-Time Production and Delivery of 3D Media

The Prometheus project has investigated new ways of creating, distributing and displaying 3D television. The tools developed will also help today’s virtual studio production. 3D content is created by extension of the principles of a virtual studio to include realistic 3D representation of actors. Several techniques for this have been developed: • Texture-mapping of live video onto rough 3D actor models. • Fully-animated 3D avatars: • Photo-realistic body model generated from several still images of a person from different viewpoints. • Addition of a detailed head model taken from two close-up images of the head. • Tracking of face and body movements of a live performer using several cameras, to derive animation data which can be applied to the face and body. • Simulation of virtual clothing which can be applied to the animated avatars. MPEG-4 is used to distribute the content in its original 3D form. The 3D scene may be rendered in a form suitable for display on a ‘glasses-free’ 3D display, based on the principle of Integral Imaging. By assembling these elements in an end-to-end chain, the project has shown how a future 3D TV system could be realised. Furthermore, the tools developed will also improve the production methods available for conventional virtual studios, by focusing on sensor-free and markerless motion capture technology, methods for the rapid creation of photo-realistic virtual humans, and real-time clothing simulation.
Theory of Torsional Chatter in Twist Drills: Model, Stability Analysis and Comparison to Test

The mechanism of torsional chatter in drilling differs qualitatively and quantitatively from other types of chatter. In this paper we show that torsional chatter can be explained by the torsional-axial coupling inherent in a twisted beam; the beam “untwists” and extends in response to an increase in cutting torque. Based on a model of this mechanism, predictions of stability boundaries and chatter frequencies are derived by frequency domain analysis, and confirmed by numerical simulation and experimental tests. The effect of the torsional-axial coupling is opposite that of traditional cutting in that an increase in cutting forces leads to axial extension and greater chip load. Because of this sign difference, the limiting depth of cut is governed by the positive real part of the frequency response function, which explains the unexpected fact that torsional chatter occurs below the natural frequency of the tool.
Ibogaine-Mediated ROS/Antioxidant Elevation in Isolated Rat Uterus Is β-Adrenergic Receptors and KATP Channels Mediated

Ibogaine effects are mediated by cellular receptors, ATP depletion followed by ROS production and antioxidant enzyme activity elevation in a dose and time dependent manner. Since the role of KATP channels and β-adrenoceptors in ROS cellular circuit was established here we explored their role in ibogaine pro-antioxidant effectiveness. Single dose of ibogaine (10 mg/L i.e., 28.8 μmol/L) was applied to isolated rat uterus (spontaneous and Ca2+-stimulated) and contractility and antioxidant enzymes activity were monitored during 4 h. Ibogaine increased amplitude and frequency of spontaneous active uteri immediately after addition that was prevented by propranolol (β1 and β2 adrenoceptors selective antagonists) and glibenclamide (KATP sensitive channels inhibitor; only frequency) pre-treatment. In Ca2+-stimulated uteri, ibogaine decreased both amplitude and frequency after 4 h. Pre-treatment with propranolol abolished ibogaine induced amplitude lowering, while glibenclamide had no effect. In both types of active uterus, ibogaine induced a decrease in SOD1 and an increase in CAT activity after 2 h. In Ca2+-stimulated uterus, there was also a decrease of SOD2 activity after 2 h. After 4 h, SOD1 activity returned to the baseline level, but GSH-Px activity increased. Pre-treatment with both propranolol and glibenclamide abolished observed changes of antioxidant enzymes activity suggesting that ibogaine pro-antioxidative effectiveness is β-adrenergic receptors and KATP channels mediated.
Cyber-Resilient Sliding-Mode Consensus Secondary Control Scheme for Islanded AC Microgrids

In this article, a cyber-resilient consensus-based distributed control scheme is proposed for islanded ac microgrids. Considering the impacts of false data injection (FDI) attacks on the conventional consensus algorithms, a hybrid solution is presented based on the combination of multiobjective sliding-mode control and communication link quality observer to provide a reliable performance against different types of FDIs. Unlike the commonly developed distributed observer-based cyber-resilient algorithms, this approach aims to form a complete localized solution without the requirements for transmission of extra distributed signals in the secondary layer. Using the proposed method, the system reliability will not be impacted by the cyber intrusions on the distributed observer terms, and the system's dynamic performance is not deteriorated by the counteracting operation resulted from adaptive distributed observers under other system-transient conditions such as load dynamics, which can be even worsened under communication delays. Using cyber-resilient offset compensation terms, performance of the proposed sliding-mode control scheme is enhanced for multiobjective regulation. Integrating the sliding-mode control with communication link observer also ensures effective isolation of the unbounded and extreme cyberattacks. Unlike the former indirect local observers, the proposed scheme operates directly based on monitoring the affected distributed signals rather than only power terms, which enhances its reliability on detection. The effectiveness of the proposed scheme is validated through a real-time model developed in Typhoon HIL-402 real-time simulator as well as the experimental tests.
Post-release survival of hand-reared tawny owls (Strix aluco) based on radio-tracking and leg-band return data

The post-release survival of hand-reared tawny owls (Strix aluco) was measured using radio-tracking and leg-band return data. Of 16 birds fitted with 2.4 g radiotelemetry tags, two shed their tags after four and nine days, respectively and one bird was recovered and the tag removed. The remaining 13 birds were tracked for between 16 and 84 days (median 38). Of these, two were found dead (one emaciated and one predated) and one was recovered alive but emaciated and was subsequently euthanased. Thirty-seven percent were radio-tracked for more than six weeks, thought to be the critical period beyond which raptors will mostly survive. Of 112 birds banded between 1995 and 2005, 18 were recovered (seven live and 11 dead). Of the seven live recoveries, three were involved in road traffic collisions. Of the dead recoveries for which the cause of death was known (n = 4), all had been involved in road traffic collisions. The time elapsed between release and recovery ranged from 1–2,246 days (median 123 days). Over 65% survived for more than six weeks. The distance travelled between release and recovery ranged between 0 and 6 km (median 0). Further work is required on the effects of hand rearing on post-release survival of rehabilitated wildlife.
Making the case for reusing and sharing data in qualitative consumer research

ABSTRACT To address the prohibitive cost of qualitative research and to increase the utility and versatility of collected data, this paper puts forth the idea of reusing and sharing qualitative data. This procedure may be employed not only across projects carried out by the same researchers (reuse), but perhaps more importantly also across scholars working separately prior to data analysis (sharing). The paper then notes possible opportunities, important considerations, barriers, benefits, and recommendations for data reuse and sharing.
Factorial Structure of Trunk Motor Qualities and Their Association with Explosive Movement Performance in Young Footballers

This study examined the factorial structure of trunk motor qualities and their associations with explosive muscular performance of football players. Ninety-one young male football players (age: 15–21 years; body height: 1.78 ± 0.07 m; body mass: 70.3 ± 7.5 kg) performed a series of tests: four standing and four seated isometric trunk strength tests, seven trunk power (medicine ball throwing) tests, four trunk endurance tests and four explosive movement performance tests. A principal component factor analysis (PCA) was used to determine the structure of trunk motor qualities, and correlational analyses were used to assess linear associations between trunk motor qualities and explosive performance. The PCA revealed four independent factors—trunk power, standing and seated isometric trunk strength, and trunk muscle endurance. Only trunk power had significant moderate, logically positive associations with sprint and vertical jump performance (common variance: 25–36%), while other associations between trunk motor factors and explosive movement performance were generally low to very low. These results indicate that trunk muscle functions of football players can be described with three independent motor qualities—trunk power, trunk strength and trunk muscle endurance, with only trunk power being moderately associated with players’ sprinting and jumping performance.
Digestive physiology, resting metabolism and methane production of captive Indian crested porcupine (Hystrix indica)

Limited physiological measurements exist for the digestive physiology of porcupines. We measured CH4 emission in three captive Indian crested porcupines (Hystrix indica; 16.1 ± 2.7 kg) fed a diet of pelleted lucerne, and measured feed intake, digestibility, and digesta mean retention time (MRT) of a solute and three particle markers (<2, 10 and 20 mm). Marker excretion patterns suggested secondary peaks indicative of caecotrophy, with MRTs of 26.4 h for the solute and 31.5, 26.8 and 26.2 h for the three particle markers, respectively. At a dry matter intake of 58 ±10 g/kg body mass0.75/day, porcupines digested 49 and 35% organic matter and neutral detergent fibre, respectively, which is in the lower range of that expected for horses on a similar diet. The respiratory quotient (CO2/O2) was 0.91, the resting metabolic rate 274 kJ/kg body mass0.75/day, and CH4 emissions averaged at 8.16 l/day and 17.9 l/kg dry matter intake. Accordingly, CH4 yield was so high that it resembled that of a hypothetical ruminant of this body mass. The results are in accord with general understanding of hystricomorph rodent digestive physiology, and support recent findings that CH4 production may be more prominent in rodents than previously thought.
