Preschoolers’ social skills and behaviour problems at home: mothers and fathers’ (dis)agreement

ABSTRACT Parents offer unique information and are recognized as the main informants about children’s social emotional functioning across time and situations. Inter-parental agreement was analysed with 100 preschoolers (M age = 54.94 months) being rated independently by their mothers and fathers, using the Portuguese version of the Preschool and Kindergarten Behaviour Scales – Second Edition (PKBS-2). Data were analysed according to four levels: index of agreement, index of disagreement, risk level and item analyses. The results indicated a low to moderate inter-parental agreement, with Pearson correlations ranging from . 35 to . 59. Fathers rated their children as having more social withdrawal problems (unique score that reached statistical significance) than mothers. No differences between mothers and fathers were found in the number of children included in risk level categories. Item analyses showed high similarities between informants concerning social skills and behaviour problems. Relevance of collecting mothers and/or fathers’ reports for research and practice purposes are discussed.
The effect of ginger root powder (Zingiber officinale) supplementation on broiler chicks performance, blood and serum constituents.

A study using one hundred and twenty eight unsexed day old broiler chicks (Ross 308) 32 birds/treatment with four replicates was conducted to evaluate the effect of ginger root powder as natural feed additives on growth performance, blood and serum constituents of broiler chickens. Four dietary treatments were formulated to meet the nutrient requirements of broiler chick containing ginger root powder at levels 0%, 0.5%, 1% and 1.5%. Result showed that significant decreased (P 0.05) in feed conversion ratio among all dietary treatments. Treatments had significant decreased (P 0.05) were observed in dressing percentage. There were no significant effect (P>0.05) on serum glucose, total protein and creatinine. Significant differences were observed in serum triglyceride and cholesterol levels. There were no significant differences (P>0.05) among all dietary treatments in Hb percentage, PCV percentage, TRBcs, MCV, MCH and MCHC percentage. The results showed that the inclusion of ginger root powder at levels 0.5% and1% in the diet , had lowering effect on cholesterol levels, and the chick may tolerate up to 1.5% without adverse effect on growth performance and blood parameters.

Trends of Precipitation Acidification and Determining Factors in China During 2006–2015

Precipitation acidification, often termed as acid rain (pH < 5.6), has been recognized as one of the major environmental issues in China since the 1980s and exerted detrimental effects on terrestrial ecosystems. In this study, we present the first investigation on the evolution of precipitation acidification over China during 2006–2015 based on a long‐term nationwide precipitation observation network and chemical transport model (Weather Research and Forest model coupled with Chemistry) simulations. The observations demonstrate a clearly decreasing trend in precipitation acidification across China from 2006 to 2015. The percentages of the number of the stations experiencing heavy acidic precipitation (annual mean pH < 5.0) decrease from ~50% in 2006 to 20% in 2015, and those with pH < 4.5 decrease from 25% to less than 5%. Our model simulations reproduced this trend and show the notable decrease in the terrestrial area (from 30% to 16%) experiencing the mean precipitation pH < 5.6. The simulation experiments indicate that the mitigation of the acidification issue in China stemmed from the large reduction in SO2 emissions (by about 60% from 2006 to 2015), which would limit the formation of sulfate and also increase the wet scavenging of gaseous ammonia. The contributions of sulfuric acid on precipitation acidification were estimated to decrease from 0.70–0.82 to 0.44–0.60 from 2006 to 2015 over northern, southern, and southwestern China. This study suggests that nitric acid plays a more important role in acidifying precipitation in northern China at present, while sulfuric acid is still the dominant factor in southern areas.
Calcium and Silicon Delivery to Artificial and Human Nails from Nail Polish Formulations

A deteriorating nail standard is a growing problem as the global prevalence of diabetes is increasing. Systemic treatment with mineral supplements may not be recommended, mainly due to the high doses required to deliver optimal therapeutic concentrations. In this work, we evaluate nail polish formulations for the local delivery of strengthening elements to the nail plate. Specifically, we assess calcium and silicon release from nail polish base coat formulations containing three different concentrations of White Portland Cement to water, as well as to artificial and human nails. The delivery of calcium and silicon to the dorsal nail plate was determined by inductively coupled plasma optical emission spectrometry, scanning electron microscopy, and energy dispersive X-ray spectroscopy. To the best of our knowledge, this is the first study showing that such dual elemental delivery to human nails can be achieved from nail polish formulations. Hence, this work may form the basis for new inventions where therapeutic functionalities can be integrated with the mechanical and cosmetic properties of a base coat nail polish. Future permeability studies are required to verify long-term effects on the nail standard, induced by the formulations under study.
Meiboscore Correlation between Contact Lenses Weares and No Contact Lenses Weares in a Young Population

Purpose: To compare the morphological changes in the meibomian glands and meibomian glands loss between contact lens and non-contact lenses wears in a young population. The contact lens wearers wore C.L. for max 6 years. Methods: Examination of the meibomian gland (MG) by using a corneal topographer CSO MODI 2 incorporating Phoenix-Meibography Imaging software module from January to June 2019. 80 volunteered students of the University of West Attics participated, and all the subjects selected had no obvious ophthalmological symptoms, aged 19 to 22 years. Results: The Arithmetic mean of Meiboscore for those who did not wear C.L. was 1,23 MGL, while for the C.L. wearers was 2,53 MGL. Conclusion: This Clinical research compares the meiboscore of contact lens wearers at a young age (min. 4 years contact lens wearers) and those who never tried to wear. This study showed that there is a relation between meibomian glands loss (MGL) and contact lens wear. Our observations showed that there a small but positive correlation, as the total period of C.L. wear increases the meiboscore increases. In addition, cumulative frequency % showed this slight increase in meiboscore. Original Research Article
Conversion of Potato Industry Waste into Fodder Yeast Biomass

In this study, we evaluate potato pulp waste as a potential raw material for obtaining yeast biomass. A portion of the carbohydrates in the potato pulp waste can thereby be converted into more valuable protein. The potato pulp waste was analyzed in terms of protein and ash content, dry mass, simple sugars, and starch content. Two kinds of hydrolysis were performed (thermo-acidic and enzymatic) to produce media for cultivating Candida guilliermondii and Pichia stipitis. The hydrolysates and post-cultivation leachates were analyzed by High Performance Liquid Chromatography (HPLC). The highest biomass yield after 48 h (39.3%) was noted for Candida guilliermondii yeast grown on enzymatic hydrolysate-based medium. Our results prove that potato waste pulp is a promising raw material for the production of yeast single-cell protein (SCP).
Correlates of social media fatigue and academic performance decrement: A large cross-sectional study

PurposeThe current study aims to investigate if different measures related to online psychosocial well-being and online behavior correlate with social media fatigue.Design/methodology/approachTo understand the antecedents and consequences of social media fatigue, the stressor-strain-outcome (SSO) framework is applied. The study consists of two cross-sectional surveys that were organized with young-adult students. Study A was conducted with 1,398 WhatsApp users (aged 19 to 27 years), while Study B was organized with 472 WhatsApp users (aged 18 to 23 years). FindingsIntensity of social media use was the strongest predictor of social media fatigue. Online social comparison and self-disclosure were also significant predictors of social media fatigue. The findings also suggest that social media fatigue further contributes to a decrease in academic performance.Originality/valueThis study builds upon the limited yet growing body of literature on a theme highly relevant for scholars, practitioners as well as social media users. The current study focuses on examining different causes of social media fatigue induced through the use of a highly popular mobile instant messaging app, WhatsApp. The SSO framework is applied to explore and establish empirical links between stressors and social media fatigue.
Distribution in Saturn's Inner Magnetosphere From 2.4 to 10 RS: A Diffusive Equilibrium Model

Electron density measurements have been obtained by the Cassini Radio and Plasma Wave Science (RPWS) instrument covering the period from 30 June 2004 to 19 April 2017, spanning latitudes up to ~30° and L values from 2.4 to 10. Near the F ring, electron densities are derived from RPWS measurements of electron plasma oscillations at high latitudes and from the Langmuir Probe (RPWS/LP) sweep data at low latitudes. The electron density measurements from the ring‐grazing orbits, beginning in December 2016, have made it possible to extend the work of a previous diffusive equilibrium model to include the distribution of the ring plasma. Beyond the ring‐grazing orbits, the densities are derived from RPWS measurements of the upper hybrid resonance frequency. These density measurements are used to anchor the fit of an expanded diffusive equilibrium density model for a two‐species plasma consisting of water group and hydrogen ions in Saturn's inner magnetosphere. Density contour plots for the two ion species and the electrons are presented. The distribution of the derived plasma densities is consistent with two primary sources, the Enceladus plume and the extended ring atmosphere. There is also an indication of a weaker plasma source at Dione. In the region just outside the A ring and in the region including the Enceladus orbit, the diffusive equilibrium model also shows the expansion of lighter ions and electrons to higher latitudes along the magnetic field lines with evidence of a weaker plasma expansion between the orbits of Tethys and Dione.
Effective Treatment for Incarcerated Obturator Hernia With Bowel Dilatation by Combined Laparoscopy and Preperitoneal Approach: A Case Report

We report a case of a 90-year-old woman with intestinal obstruction due to left-sided incarcerated obturator hernia, which was revealed using computed tomography. Emergency surgerywas performed using laparoscopy, which showed a dilated small intestine and bilateral obturator hernia in the intraperitoneal space. After reducing incarceration of the small intestine using laparoscopy, we approached the bilateral preperitoneal space and inserted a Kugel patch via a small lower abdominal median incision (approximately 4 cm). The patient was discharged on postoperative day 10 and showed no recurrence at the 18-month follow-up. Although relatively rare, obturator hernia can significantly cause intestinal obstruction. It has no specific clinical symptoms and is thus often difficult to diagnose. Treating obturator hernia is essential; however, mesh infection, recurrence, and opposite side of the obturator hernia should be carefully monitored. Although laparoscopy is used for treating obturator hernia, it may be difficult in patients with intestinal obstruction. In this case, a surgical technique combining laparoscopy and preperitoneal space approach via a small lower abdominal median incision was used to effectively treat an incarcerated occult bilateral obturator hernia.
Cyber Security for Smart Cities

When the systems in smart cities are classified, there are generally eight categories. These are Smart Transportation, Smart Governance, Smart Economy, Smart Environment, Smart Health, Smart Industry, Smart Security, and Smart Life. There are dozens of intelligent systems in each category. The correct operation of these systems is as important as their security. For example, if any infiltration or intrusion into an intelligent system such as smart intersections, smart roads, crowd management, city noise mapping, smart energy, natural gas and water supply systems, early warning systems, the city may be in great danger. Natural disasters can be experienced as well as fatal consequences that affect human life. Therefore, the rulers of the smart city should always be on the alert and ensure the cyber security of the smart city. Cyber refers to electronic environments such as computer, server, device, hardware, software, protocol, algorithm, process, policy, process, laboratory, system. Cyber security is a set of methods, policies, concepts, and guidelines, risk management approaches, activities, trainings, best practice experiences and technologies used to protect the information assets of institutions, organizations and users. Intelligent strategies against cyber-attacks should be developed as the city environment created by smart systems has become very attractive for data thieves. Otherwise, a smart city can bring people closer to bad situations rather than bring people closer to technology. In this study, Cyber Security in Smart cities will be explained. The current literature review will reveal the latest trends in these two areas. The study is considered to be beneficial for smart cities technology developers.
Leveraging Sport Events for Tourism Development: The Event Portfolio Perspective

Abstract Despite the increasing use of sport events in portfolios as a tourism place-making tool, academic research on this phenomenon is sparse within sport management. In response, the purpose of this theoretical contribution is to review and synthesize pertinent literature on sport events and tourism management in order to set the ground towards developing a policy framework for leveraging event portfolios and creating value for the host destination’s tourism product. To this end, an event portfolio tourism leveraging model is proposed building upon the theoretical tenets of a holistic event portfolio approach integrated with the perspectives on economic event leverage, event tourism portfolio, and destination capitals. It is argued that the proposed model can be used to more effectively integrate sport events into destination development. In doing so, the paper calls for the need to conduct more systematic, nuanced and comprehensive investigations within sport event management that will build knowledge on leveraging multiple events for obtaining multiple benefits.
Evaluation of fire safety measures at local universities in Kenya with reference to fire risk reduction rules ln.59, 2007

Fire-related accidents often result in injuries and sometimes death, which can be prevented through compliance to legislation and public awareness on fire safety. This study establishes fire safety measures in place in local universities in Kenya, and compared the compliance status between private and public universities on essential fire safety measures based on the stipulations of the fire risk reduction Rules, LN 59 of 2007. Data was collected using questionnaires from seven universities (three public and four private) targeting a sample size of 481 respondents. Site inspections were also conducted. The average duration worked by the respondents was significantly different with 53% of staff in the public universities having worked over 8 years at the universities as compared to 30% in the private universities. This had no significant effect on the levels of fire safety awareness amongst the staff as none of the institutions had formal policies and programmes on fire safety. More than 74% (n=481) of employees were not aware on any fire training programmes in place with no significant difference in both categories (χ2 = 3.72; p> 0.05, df = 2). Failure to conduct regular fire evacuation drills was common to both categories (χ2 = 3.16; p> 0.05, df = 2). The study found that the workplaces were adequately equipped with Fire exits signs (98%), fire extinguishers (99%), hose reels (82%) and had fire action procedures posted (88%). Despite the selected public and private universities having a mean existence of 47 years and 14.25 years respectively, there is equally low compliance with the requirement to provide emergency lighting, automatic fire suppression systems, fire detection and alarm systems and fire Hydrants. Private universities however complied marginally better than public universities on the installation of these essential equipment as they have relatively newer premises that have been constructed in compliance with current building codes. The study recommends the development of comprehensive fire safety policies and programs that will cover prevention, protection and emergency response backed by university management endorsement and support. The Directorate of occupational safety and health services should also make the public aware of these rules through regular training, outreach programs and enforcement.

Lengthy unpaid placements in social work: exploring the impacts on student wellbeing

ABSTRACT In Australia, there are 130,000 students studying social work across 30 universities. The Australian Association of Social Workers (AASW) mandates the completion of at least 1,000 hours of field education for qualification, across at least two placements in different fields of practice. This means a full-time social work placement at 7.5 hours per day is typically just under 3.5 months’ duration. Yet, recent Australian research has demonstrated that students experience significant levels of financial and other stress during lengthy, unpaid placements. In response to this, we surveyed Bachelor of Social Work (BSW) students who were currently undertaking or had recently undertaken (n = 60) their first or second field placement at Victoria University, in Australia to elicit their feedback on their experiences of lengthy unpaid placements. The descriptive survey was completed anonymously online and consisted of 38 short answer questions that elicited demographic information and respondents’ opinions on key field placement criteria. The results of this study have important implications for field education, as it adds to the existing calls for a reworking of the AASW accreditation standards to address this issue. Future research could incorporate feedback from field liaisons, and field directors.
An approach to the analysis of hydroelastic vibrations of electromechanical systems, based on the solution of the non-classical eigenvalue problem

Abstract In this paper we introduce an approach to solution of the problem of natural vibrations of piecewise homogeneous electroelastic bodies connected to external passive electric circuits and interacting with a quiescent fluid. A mathematical formulation of the problem, and a variant of its numerical implementation based on the finite element method are presented. Based on the obtained results we extend the previously developed approach to the selection of optimal parameters of shunt circuits for damping of vibrations of electroelastic structures in the case of their interaction with a fluid.
The role of grit and classroom enjoyment in EFL learners’ willingness to communicate

ABSTRACT This interdisciplinary study investigates whether, and to what extent, grit (consisting of perseverance of effort and consistency of interests) and classroom enjoyment are linked with EFL learners’ willingness to communicate in a second language (L2 WTC), the final psychological step before actual English communication. To this end, three groups of Korean EFL learners (N = 647) from five schools, who at the time of the study had no overseas experience, were surveyed: middle school (n = 137), high school (n = 323), and university students (n = 187). Results of hierarchical regression analyses show that grit (perseverance of effort) and classroom enjoyment are predictors of all cohorts’ L2 WTC, while grit (consistency of interests) is not predictive of L2 WTC among all participants. These results suggest that L2 teachers, who instruct in a relatively monolingual and monocultural EFL classroom, can boost learners’ L2 WTC by encouraging continuous efforts to initiate English communication. Moreover, by creating a positive classroom environment, EFL teachers can increase learners’ level of L2 WTC and potentially boost their English communicative competence. Theoretically, these findings support an emerging view of the application of positive psychology in L2 learning and teaching.
Linear and symmetric conductance response of magnetic domain wall type spin-memristor for analog neuromorphic computing

We developed a three-terminal spintronic memristor named spin-memristor for the artificial synapse of neuromorphic devices. Current-induced domain wall (DW) motion type magnetoresistance was used to generate variable analog conductance changes. Magnetic tunnel junction with a perpendicularly magnetized DW layer was fabricated on a silicon substrate. Due to the forward and backward DW motions, a linear and symmetric conductance response was achieved. The impact of memristive behavior on neural networks was evaluated using numerical simulation of hand-written digit recognition. This spin-memristor is identified as one of the promising candidates for artificial synapses in analog neuromorphic devices.
