Convergent Validity of a Quick Online Self-Administered Measure of Verbal IQ for Psychology Researchers
Authors: Logos Katie , Brewer Neil , Young Robyn L.
Published: October 2021

Verbal intelligence—which relates to memory performance, abstract reasoning, and g—is often important to account for within psychological research. However, the time demands and financial costs associated with researcher-administered testing using valid measures of intelligence limit researchers’ ability to include such measures within their research. To address this issue, we examined the convergent validity of two tests of verbal intelligence that could be self-administered online with the well-validated Wechsler Abbreviated Scale of Intelligence–Second Edition (WASI-II). An undergraduate sample of participants (N = 104) completed the Self-Administered Verbal IQ Test (SA-VIQT), with a subsection (n = 64) completing the Self-Administered Full Scale IQ Test (SA-FSIQT), both made available online by Open-Source Psychometrics Project. Additionally, all participants were administered the Verbal Comprehension Index (VCI) of WASI-II by a trained researcher, with a subsection administered the full WASI-II including the Perceptual Reasoning Index (PRI) (n = 72). Both online tests demonstrated convergent validity with the WASI-II. While the online tests may only deliver a crude indicator of verbal intelligence, they provide researchers the opportunity for statistical control or screening of participants across large samples in an efficient manner not possible when using researcher-administered testing methods.
Impact of Electronic Monitoring on Employees: A Meta-Analysis
Authors: Siegel Rudolf , König Cornelius J. , Lazar Veronika
Published: October 2021

Electronic monitoring is more and more widespread and affects many employees around the globe. The current meta analysis collected data of 59 independent samples (with 223 effect sizes) to estimate the effect of electronic monitoring on job satisfaction, stress, and performance. A random-effects model indicated a small negative effect of monitoring on job satisfaction, r=-.09, and a small positive effect on stress, r=.12. There was no relationship with performance, r=-.01. Even if the effects of monitoring on job satisfaction and stress are small, taking the large number of employees who are monitored for several hours a day into account, these effects may have a severe and negative impact on employees’ well-being. Performance maintenance is the main justification for the use of electronic monitoring, but the non-existing relationship of monitoring with performance questions the validity of this justification.
An Investigation of the Effects of Social Media Browsing on Leisure Solitude in Emerging Adults
Authors: Nguyen Thuy-vy Thi
Published: October 2021

This exploratory study investigated the effect of social media use on emerging adults’ experiences with leisure solitude – periods of free time spent alone. First, one 14-day diary study (n = 109) was conducted to explore the effects of leisure solitude on daily affects and self-experiences and whether social media added any additional benefits or detriments. Then, two experimental studies (Study 2: n = 146; Study 3: n = 249) were conducted to home in on the effects of social media on lab-facilitated leisure solitude. Results across 3 studies revealed little evidence that social media interfered with the regulatory benefits of leisure solitude. Specifically, spending time in leisure solitude lowered arousal levels and increased calmness and relaxation at the end of the day and after just 15 minutes of it in the lab, and this effect was found despite whether participants engaged in social media or not. One interesting finding emerged: browsing on social media created feelings of inauthenticity in solitude. This finding was discussed in connection with the theory of emerging adulthood, which shed light on how emerging adults make sense of the uncertainty experienced in online space.

Prediabetes is a condition in which there is elevated blood sugar does not reach the criterion accepted for an outright diagnosis of diabetes. The researchers are struggling to search an effective, satisfactory and harmless remedy. In present day, the Prediabetes is managed by lifestyle modification such as diet and exercise. They are helpful in controlling the condition but, even then a large population of Prediabetic patients turn out to be diabetic. Improper dietary habbits and sedentary life styles are the major causative factors described for Prediabetes, which closely resemblance with the etiology of Kaphaja prameha. In our classics, Acharyas has mentioned that the person inflicted with Kaphaja Prameha should be administered the Apatarpana Chikitsa (depletion therapy) due to the involvement of vitiated Kleda, Meda and Kapha. We hereby present a case report of 63 year old male patient who was diagnosed as prediabetic according to American Diabetic Association. The patient was treated with Snehapana with Murchitha Sarsapa Taila(6 days) followed by Virechana with Trivrt Churna (1 day) and Nisakathakadi kashaya (3 months). The clinical effects were assessed on the basis of subjective and objective parameters. After the completion of the treatment, his FPG 116 mg/dL reduced to 98 mg/dL, OGTT 162 mg/dL reduced to 134 mg/dL and HbA1c level 6.3% reduced to 5.6%.

Agrimonia pilosa Ledeb (AL) has received considerable attention as a herbal medicine for its applications in ethnopharmacology with heath benefits. This study aimed to investigate antioxidant activities and A549 growth inhibitory capacity from its root extract (RE) and aerial parts extract (AE). The 50% ethanol extracts were used for the tests. The total polyphenol content and the antioxidant effects comprising ABTS+ and DPPH free radical scavenging activities were evaluated. Phenolic compounds in the extracts were isolated using high performance liquid chromatography (HPLC). Lactate dehydrogenase released in medium was also evaluated. Total phenolic and flavonoid content, and in vitro antioxidant potential of the RE were higher (p<0.01) than that of the AE. Two individual phenolic compounds consisting of 4-hydroxybenzoic acid and p-coumaric acid were firstly identified in both by HPLC. The RE exhibited higher A549 inhibitory capacity compared to the AE and activated the apoptotic proteins of bcl-2, bax, bad, caspase-3 and caspase-9 in A549. In conclusion, the AL extracts were more effective in antioxidant and A549 cells inhibitory capacity.

Published: October 2021

Background: Forensic Dentistry is one of the branch of Forensic Medicine which deals with the complete handling of dental evidence, estimation and examination and the evidence obtained would be used in the court for justice. Kvaal and Solheim given a method used on adults for calculation of age with the help of morphological and radiological methods, but extraction was still required. Hence to improve this procedure Kvaal et al made a method which is totally based on radiological analysis.
Aims and Objective: The present study was designed to compare the forensic age assessment using Kvaal’s method and digital orthopantomographs with the actual age of the subjects.
Materials and Methods: Present observational study was conducted in subjects with all the required complement of teeth on either right or left side, completely erupted clinical crown, without any morphological abnormalities for age estimation by Kvaal’s method with digital orthopantomograph as and compared with actual age of subjects.
Results: In the present study out of 100 subjects, maximum number of subjects i.e. 61 were in the age group of 20 – 29 and minimum number of subjects i.e. 7 were in the age group of 50 –59. 43 were females and 57 were males. The regression equation was derived for all six studied teeth and coefficient of determination R2 was found for all the individual six teeth. Coefficient of determination was highest for lower first premolar (0.517) followed by upper central incisor (0.178), lower canine (0.134), lower lateral incisors, upper second premolar and upper lateral incisors. M & W-L were found significant predictors for lower first premolar, lower canine and upper central incisors. Similarly, coefficient of determination (R2) was significant higher for lower three teeth (0.478) than upper three teeth (0.069) with M & W-L were significant predictor. Regression equation derived for all six teeth together shows significant coefficient of determination R2(0.430) with M, W-L both are significant predictors. No statistically significant difference between the actual age and estimated age for all individual six teeth was noted. Mean difference lowest for lower first premolar (0.001) followed by lower canine (0.007).
Conclusion: We noted that age assessment using Kvaal’s method with digital orthopantomographas and actual age of the subjects were comparable & no significant difference was noted. Kvaal’s method with digital orthopantomographas is a better option for age estimation without teeth removal.

Published: October 2021

Municipal Solid Waste is one of the demanding environmental challenges faced by many municipalities in Nepal. Current practices and systems in Nepal being unable to deal with the increasing volumes of waste generated by an increasing urban population and its impact on the environment and public health. This paper reviewed the challenges, practices and discusses key policies, legislative and institutional provisions made by the government regarding solid waste management in Nepal. Both published and unpublished documents, reports; articles and books were collected, reviewed, and analyzed. The result shows that an appropriate legal provision including policy and strategic framework needs to be developed for three tiers of government such as federal, provincial, and local. The initiatives of local governments and the public could play a significant role in managing solid wastes. Thus, strengthening the capacity of local governments is indispensable, as primarily they are mandated to provide solid waste management. The public-private partnership offers opportunities for operational efficiency and cost-effectiveness. In summary, for the environment-friendly management of solid wastes, academia could contribute a supportive role in developing and reforming policy, strategy, and guidelines and, strengthening the capacity of concerns at all levels.

Feasibility Study of Building Integrated Photovoltaic (BIPV) as a Building Envelope Material in Europe
Authors: Gholami Hassan
Published: October 2021

Buildings play a vital role as regards the energy efficiency of urban areas since they are responsible for a significant portion of the energy demand of urban areas. In Europe, building energy use accounts for 41% of the total energy consumption of the cities [1]. Urban energy transition has recently come about by intensifying the endeavour towards promoting distributed or decentralised energy generation (DG) and realign the energy production and consumption of buildings. One of the leading solutions which can be of great assistance to contribute towards such an approach is building integrated photovoltaic (BIPV) systems. BIPV is a PV system on the building skin serving as both a building envelope material and a power generator. An alternative that is not covered here is PV systems nearly – in the landscape or garden. There is a tendency currently in the market to use BIPV systems in the part of the building skins with the highest incident solar radiation and, therefore, higher electricity production as an output. These areas in the northern hemisphere are roof and south façade. However, employing other facades and areas of building skins also results in many advantages. The possibility to achieve zero energy buildings (ZEB) or even plus energy building goals, using different facades and orientations of buildings to have a distributed electricity generation during the day, and the system's contribution in reinforcing the energy performance of the building skin are some advantages. To place PV modules so that they deliver energy when the energy need in the building is highest is also of importance as it reduces the need for storage. Therefore, this thesis focuses on building integrated photovoltaic systems (BIPV) and their feasibility as a building envelope material in Europe. The main research question is defined as follows: Is the BIPV system as an alternative for the more usual building envelope materials feasible for the entire skin of buildings in Europe? The goal is to investigate the technical and economic aspects of such a solution in two steps. Finally, the project seeks to briefly discover the potential and challenges of such a solution in the energy transition of cities. Both qualitative and quantitative methodologies are employed in this project, and most of the analyses are based on the data obtained from the Photovoltaic Geographical Information System (PVGIS) and the Surface Solar Radiation Data Set - Heliosat (SARAH) dataset. The results are expected to help the end-users, architects and urban planners to acknowledge the BIPV system as a suitable option for the building skins in Europe and steer governments or decision-makers to promote the technology by rational subsidies and incentives (where it is needed). This can contribute towards making cities as well as more rural areas into “power stations”.
Dopuszczalność stosowania przepisów prawa spółdzielczego do trybu likwidacji fundacji. Rozważania w kontekście poglądów Henryka Ciocha

The Polish statutory regulations concerning the liquidation of Foundations are contained in Article 15 of the Act of 6 April 1984 concerning Foundations, hereinafter referred to as the “Act on Foundations”. The provisions of this Article constitute the only legal basis applicable to the entire complicated process of eliminating the legal existence of a Foundation as part of its liquidation. The Act on Foundations does not establish the course of liquidation proceedings, in this respect it refers to the provisions of the Statutes. Generality and imprecisiness of the applicable legal provisions regarding the liquidation of Foundations has been the subject of universal criticism in the legal literature; the current regulation is considered inappropriate and insufficient. De lege lata indicates a clear need to apply legal solutions contained in other legal acts governing the liquidation of other legal entities to the liquidation of Foundations. Although it has been variously postulated that Foundations should be liquidated according to the laws governing the liquidation of cooperatives, Associations, or according to the Code of Commercial Partnerships and Companies, it is generally acknowledged that the application of the law governing cooperatives is most closely related to the liquidation of Foundations. It is worth underscoring that the proceedings for liquidating a legal cooperative are regulated rather thoroughly and appropriately and as a result they are often used.

Published: October 2021

Feedback is an essential part of the teaching/learning processes. This statement is especially true in the introductory communication course where students receive feedback throughout the presentational speaking process. This paper explores how students define useful feedback based on 1,600 qualitative questionnaires that asked students about their perceptions of feedback. A thematic analysis of a randomly selected subset of 163 responses uncovered two themes: (1) feedback content characteristics (e.g., specific, constructive, praiseworthy, and purposive) and (2) process of instructor-provided feedback (e.g., iterative, timely). Based on these findings, a set of best practices for providing feedback is offered as a means to improve teaching/learning in the introductory communication course.

Araştırmanın sonuçlarına göre, yöneticilerin okul merkezli yönetimin merkezi yönetimden farkına ilişkin en öne çıkan konu inisiyatif alma olmuştur. Yöneticilerin okul merkezli yönetim algılarında en çok okulun merkezde olması vurgulanmıştır. Okulun kendi bütçesini hazırlamasının, okulun gereksinimlerini karşılama konusunda okula bir fırsat sağlayacağı düşünülmektedir. Öğretim programı ve ders kitaplarının hazırlanması sürecinde uzman desteğine ihtiyaç duyulacağı belirtilmiştir. Okulun kendi personelini işe alması noktasında ise henüz yeterli alt yapının olmadığı algısı vardır. Planlama ve programlamaların okulun ve öğrencinin ihtiyaçları çerçevesinde yapılması gerektiği ortaya çıkmıştır. Okul merkezli yönetimin, çalışan verimliliği, okula aidiyet ve öğrenciye uygunluk açısından olumlu olarak görüldüğü; siyasi ve yandaş baskısı açısından olumsuz olarak görüldüğü tespit edilmiştir. Eğitim-öğretimle ilgili alınan kararlarda odak noktası okulun ve öğrencinin başarısını artırmak olmalıdır. Okul merkezli yönetimde yeni fikirlere açık olmak da önemli bir konudur. Yönetici görüşleri doğrultusunda, personel istihdamında liyakate dikkat edilmeli ve alınan kararlarda paydaşların fikirlerine yer verilmelidir.

Amyotrophic lateral sclerosis (ALS) is a disease where upper and lower motor neurons die, and it is often associated with mutations of superoxide dismutase 1 (SOD1). We have used mouse models to compare physiologic and morphologic characteristics of cervical motor neurons in wild-type and mutant animals. Slices of the cervical spinal cord were prepared from old wild-type and mutant G93A and G85R mice, and intracellular recordings of membrane potential, resistance and responses to application of excitatory neurotransmitters were studied. Some motor neurons were injected with Lucifer Yellow for morphological analysis. There were no significant differences between membrane potential in the SOD1 mutants and aged wild-type mice, but membrane resistance was somewhat higher in the mutant motor neurons. Dendrites of the mutant motor neurons were not responsive to ionophoretic application of excitatory amino acids, although the cell body responded strongly. In Lucifer-filled cells, the dendrites were found to disappear. Mutant motor neurons were sometimes spontaneously active. Responses of mutant motor neurons to perfused glutamate with varying calcium concentrations in the Ringer’s solution were different from those of the wild-type cells.

Objective: The aim of this study was to assess the therapeutic effects of Jianpi Liqi decoction (JPLQD) in hepatocellular carcinoma (HCC) and explore its underlying mechanisms. Methods: The characteristics and outcomes of HCC patients with intermediate stage B who underwent sequential conventional transcatheter arterial chemoembolization (cTACE) and radiofrequency ablation (RFA) only or in conjunction with JPLQD were analysed retrospectively. The plasma proteins were screened using label-free quantitative proteomics analysis. The effective mechanisms of JPLQD were predicted through network pharmacology approach and partially verified by ELISA. Results: Clinical research demonstrated that the Karnofsky Performance Status (KPS), traditional Chinese medicine (TCM) syndrome scores, neutropenia and bilirubin, median progression-free survival (PFS), and median overall survival (OS) in HCC patients treated with JPLQD were superior to those in patients not treated with JPLQD (all P<0.05). The analysis of network pharmacology, combined with proteomics, suggested that 52 compounds targeted 80 potential targets, which were involved in the regulation of multiple signaling pathways, especially affecting the apoptosis-related pathways including TNF, p53, PI3K-AKT, and MAPK. Plasma IGFBP3 and CA2 were significantly up-regulated in HCC patients with sequential cTACE and RFA therapy treated with JPLQD than those in patients not treated with JPLQD (P<0.001). The AUC of the IGFBP3 and CA2 panel, estimated using ROC analysis for JPLQD efficacy evaluation, was 0.867. Conclusion: These data suggested that JPLQD improves the quality of life, prolongs the overall survival, protects liver function in HCC patients, and exhibits an anticancer activity against HCC. IGFBP3 and CA2 panels may be potential therapeutic targets and indicators in the efficacy evaluation for JPLQD treatment, and the effective mechanisms involved in the regulation of multiple signaling pathways, possibly affected the regulation of apoptosis.

In this article we consider the questions of one-valued solvability and numerical realization of initial value problem for a nonlinear Hilfer type fractional differential equation with maxima. By the aid of uncomplicated integral transformation based on Dirichlet formula, this initial value problem is reduced to the nonlinear Volterra type fractional integral equation. The theorem of existence and uniqueness of the solution of given initial value problem in the segment under consideration is proved. For numerical realization of solution the generalized Jacobi–Galerkin method is applied. Illustrative examples are provided.
Magnetic and spectrometric studies of Al-Gor area, Southwestern Sinai, Egypt
Authors: ZAEIMAH Mostafa A. M.
Published: October 2021

Al-Gor area is a part of Southwestern Sinai of Egypt. It is considered as one of the most promising areas for mineralization in Egypt, being rich in many mineral deposits of: manganese, iron, copper, zinc, lead, cobalt, nickel, silver, gibbsite, and uranium. Besides, some industrial ore minerals such as kaolin and glass sand,… etc. are also found in this area. The area was studied by Gama-ray spectrometry to trace the radioactive anomalies, their concentrations and their relationship to the existing rocks, and by magnetic survey to study the relationship of radioactive anomalies and their trends with the trends of geological structures. The gamma-ray spectrometric maps show different levels over the surveyed area, which reflect contrasting radioelement contents for the exposed various rock types. The highest radiospectrometric levels are located in the northwest southeast direction and some scattered parts all over the study area. They are mainly associated with Um-Bogma Formation, bearing gibbsite. The study area possesses radiospectrometric ranging between 0.6 and 110.9 Ur as a total-count, 0.1 to 1.8 % for K, 0.1 to 99 ppm for eU and 0.1 to 23 ppm for eTh. The qualitative analyses of magnetic data show the existences of a number of different magnetic anomalies, with different amplitudes and frequencies as well as trends. From the application of spectral analyses of magnetic data, the regional and residual depths of magnetic anomalies can be computed. The first depth represents the regional (deep-seated) anomalies, at about 75 m and the residual (shallow-seated) anomalies, at about 20 m. The trends of the structures as derived from the spectrometric and ratio maps correspond to those inferred from the residual-component magnetic map, which reflects the effect of structures on the concentration of radioactive elements and, consequently mineralization.

We used 2D integrated geophysical modelling approach to calculate the temperature distribution in the lithosphere along profile VII passing through the Eastern Carpathians. With assigned rheological parameters of rocks and obtained temperature field, we derived the rheological model of the lithosphere along the studied profile. We have calculated the strength distribution in the lithosphere, based on the brittle and ductile deformation, for compressional and extensional regimes and the vertically integrated strength along the profile. To illustrate the strength distribution in different tectonic units, we have calculated the yield strength envelopes for chosen lithospheric columns. Ours results show that the dominant regime is compressional and the largest strength occurs on the boundary between the upper and lower crust. Along the studied profile, the strength decreases from its high values in the European platform towards its minimum in the Trans-European Suture Zone (TESZ). In the Eastern Carpathians, the strength increases, reaches two maxima, the first in the Outer Eastern Carpathians, and the second in the Inner Eastern Carpathians, where the highest values of strength can be observed. Another local maximum along the profile can be observed in the Apuseni Mountains, while the minimal strength is observed in the Transylvanian Basin. The diverse rheological behaviour of studied tectonic units seems to be in accordance with their lithospheric structure and tectonics.
