Use of knowledge pieces and context features during the transfer process in physics tasks

ABSTRACT In this article, we present a qualitative study examining students’ thoughts and strategies while transferring concepts about energy in physics. We include theoretical approaches of existing transfer research and findings from think-aloud interviews with 20 students of different ages and school levels to develop a framework for analysing the transfer process. The results of both traditional transfer studies and modern approaches, such as the ‘Actor-Oriented Transfer perspective’ (AOT) and ‘Coordination Class Theory’ (CCT), are regarded as a theoretical foundation for the framework. Our empirical data involves the statements of students solving a physics task with questions regarding the energy concept, which we used to inductively derive categories for our framework. We conclude that the transfer process is highly individual and that our framework can make this process visible. Knowledge can be transferred with or without a relation to the contextual features of the transfer situation, and it is possible that students describe the context situation itself without relating it to their existing knowledge pieces. Finally, we found four metacognitive strategies that students use while transferring their knowledge. The findings will help teachers to focus on the applicability of knowledge and on practising the use of transfer strategies.

UNIDO also assists in building capacity for the development and deployment of environmental monitoring systems that combine inspections by enterprise and government to assess performance and measure compliance with operational licences.
Stability of a Rock Tunnel Passing through Talus-Like Formations: A Case Study in Southwestern China

Tayi tunnel is one of the component tunnels in the Jian-Ge-Yuan Highway Project located in Yunnan Province, southeast of China. It mainly passes through talus-like formations comprised of rock blocks of diverse sizes and weak interlayers with clayey soils with different fractions. Such a special composition leads to the loose and fractured structure of talus-like formations, which is highly sensitive to the excavation perturbation. Therefore, Tayi tunnel has become the controlled pot of the whole highway project as the construction speed has to be slowed down to reduce the deformation of surrounding talus-like rock mass. To better understand the tunnel-induced ground response and the interaction between the surrounding rock mass and tunnel lining, a comprehensive in situ monitoring program was set up. The in situ monitoring contents included the surrounding rock pressure on the primary lining, the primary lining deformation, and the stress of steel arches. Based on the monitoring data, the temporal and the long-term spatial characteristics of mechanical behavior of surrounding rock mass and lining structure due to the excavation process were analyzed and discussed. It is found that the excavation of lower benches released the surrounding rock pressure around upper benches, resulting in the decrease of the surrounding rock pressure on the primary lining and the stress of steel arches. In addition, the monitoring data revealed that the primary lining sustained bias pressure from the surrounding rock mass, which thereby caused unsymmetrical deformation of the primary lining, in accordance with the monitored displacement data. A dynamically adaptive support system was implemented to strengthen the bearing capacity of the lining system especially in the region of an extremely weak rock mass. After such treatment, the deformation of the primary lining has been well controlled and the construction speed has been considerably enhanced.
The Fight against Female Genital Mutilation/Cutting among the Ejaghams of Cameroon: Kinks in the Legal Approach and Implications for Public Health Practice

Abstract Female genital mutilation/cutting (FGM/C) is one of the most prevalent harmful cultural practices against women and girls in many African countries. We identified reasons for the failure of the legal approach to stop FGC practice in the Ejagham region Southwest of Cameroon through multi-locale ethnographic fieldwork. The reasons revolve around the belief that FGM is useful for the reduction of sexual immorality among women, removal of sexual ambiguity and improving genital esthetics, a feministic symbol and cultural identity, and the government’s socio-economic neglect of the Ejagham communities; the basis for resistance. Non-legal approaches involving community development and women empowerment have been proposed for fighting FGC.
Comparison of Two Different Management Practices under Organic Farming System

Organic farmers usually do not have the opportunity to address the actual symptoms of deficiency through the foliar application of synthetic fertilization, therefore, the main treatment is realized by green manure crop cultivation and application of organic fertilizers. The aim of this long-term experiment was to compare two different production systems with and without livestock in terms of organic farming, and a control variant with no fertilization was also included (treatment 1). The production system without animal husbandry was based on solely the application of renewable external resources (compost or digestate) (treatment 2) and the same fertilization with the addition of auxiliary substances (AS) (treatment 3). The production system with animal husbandry included utilization of fertilizers produced on the farm (fermented urine or manure) using solely farm fertilizers (treatment 4) and in addition with AS (treatment 5). Each treatment had three replications. This work describes the average yields from four experimental years and five experimental localities. Winter wheat, potatoes, winter wheat spelt and legume-cereal mix with corn were used and examined as model crops during the first four years of this long-term research. The highest average yield of winter wheat grain and potato tubers during the first two years of the experiment were obtained after the treatments 2 (7.1 t/ha grain, 33.9 t/ha tubers) and 3 (7.0 t/ha grain, 34.1 t/ha tubers). The several times higher nitrogen content in applied digestate and compost in comparison with fermented urine and manure was probably the reason for such results. On the contrary, the results obtained from the third (spelt) and fourth (LCM and corn) experimental years favored treatment 4 (5.5 t/ha grain, 4.6 cereal unit/ha) and 5 (5.4 t/ha grain, 4.7 cereal unit/ha) from the long-term point of view. After four experimental years, the presented results supported the application of farm fertilizers as a preferable option. The treatments with additional application of AS did not provide a higher yield, therefore, such an application seems unnecessary.
A Comparison between the Spatial Intelligence of the Freshman Engineering Students of Sharif University of Technology and Debrecen University

The goal of this paper is to compare freshman engineering students' spatial abilities (Spatial Intelligence) at two universities: Sharif University in Tehran and Debrecen University of Hungary, focusing on both their final mathematical exam performance and their gender so as to ascertain whether the students differ significantly in terms of their spatial abilities and/or their problem solving methods. The tests used to measure spatial intelligence performance and mental rotation was the Purdue Spatial Visualization Test (PSVT Branoff). The test results have been statistically evaluated and conclusions formulated. The results show that there was no significant difference between Iranian and Hungarian freshman engineering students in the performance of mental rotation tasks. However, a general gender difference in spatial ability performance was evident among the Hungarian students but not among the Iranians. The results also shed light on spatial rotation problem-solving methods that appear to be largely specific to females.

Fuel Effects on Regulated and Unregulated Emissions from Two Commercial Euro V and Euro VI Road Transport Vehicles

Substantial advances in European road vehicle emissions have been achieved over the past three decades driven by strengthening revisions in emissions legislation and enabled by advances in fuel, vehicle engine and emissions control technologies. As both vehicle technology and emissions legislation in Europe continue to evolve, Concawe has conducted a study to examine the effects that fuels can have on emissions, in this case from commercial road vehicles. A bus certified to Euro VI emissions level and a delivery truck certified to Euro V emissions level have been tested on a chassis-dyno over the World Harmonized Vehicle Cycle (WHVC) and Transport for London Urban Inter-Peak (TfL UIP) test cycles with six fuels: an EN590-compliant B5 (petroleum diesel containing 5% biodiesel by volume), a bioderived paraffinic diesel, a 50:50 blend of the aforementioned fuels, a low-density petroleum-derived B5, a B30 and the same B30 additized with a high dose of cetane number improver (CNI). Results show reduced NOx reductant (AdBlue) consumption with paraffinic diesel in the Euro VI bus due to lower engine-out NOx emissions. More surprisingly, higher hydrocarbon emissions were observed with some low-density hydrocarbon fuels in the Euro V truck. Compared to B5, B30 with and without CNI did not affect tank-to-wheel (TTW) CO2, volumetric fuel consumption or NOx by statistically significant margins. When considered with the findings of a complementary light-duty study, it is apparent that low-density diesel fuels could offer overall benefits to both emissions affecting local air quality and to greenhouse gas emissions on a TTW basis. The addition of higher fatty acid methyl ester (FAME) levels to fuels can be used to increase renewable fuel contribution resulting in no penalty in NOx emissions from modern technology vehicles. Compatibility of these fuels with the existing vehicle fleet would require further specific consideration. Outside of fuel properties considerations, Euro VI aftertreatment systems can increase N2O emissions at the tailpipe through chemical reactions in the catalyst. This can translate into about 10% contribution of N2O emissions to the overall GHG emissions of the vehicle.
Theme-Based Teaching to Promote Oral Fluency in a University in Colombia

The present qualitative study with an action research orientation focuses on the strengthening of students’ oral fluency in English through the implementation of six theme-based teaching workshops. The participants were students of an EFL pre-intermediate English language course in the institute of foreign languages at the Technological University of Pereira, in Risaralda State, Colombia. Besides the implementation of theme-based teaching, this study includes the speaking phases of rehearsal, performance, and debriefing to impact students’ oral fluency. This project emerged from an exhaustive needs analysis which showed that the university’s students, as future professionals, had difficulties with their oral performance i.e. their being unable to speak about topics related to their university life in English; hence, the need of including themes aligned with their academic contexts was highlighted with the purpose of helping them improve their oral fluency in English. The findings indicate that the students improved in their oral fluency in terms of vocabulary, intonation, and a reduction in the number of long pauses when speaking in English.
Assessment and Brain Training of Patients Experiencing Head and Facial Pain with a Distortion of Orofacial Somatorepresentation: A Narrative Review

The management of patients experiencing chronic orofacial pain is a great challenge, due to the complexity of chronic pain itself, combined with an increased peripheral sensitization in the craniofacial itself. Therefore, patients with orofacial pain may present a clear distortion of the somatorepresentation after some time. In this review, the authors develop a neurophysiological explanation of orofacial distortion, as well as propose assessment and treatment options, based on scarcely available scientific evidence and their own clinical experience. The assessments of facial somatosensory, cognitive-affective and motor dysfunctions are crucial to establish the most accurate treatment; the assessment tools are described in the article. Two-point discrimination, laterality recognition and emotion recognition are altered in patients with orofacial pain. Other sensorimotor assessment tools, such as motor acuity and auditory acuity, are also explained. Finally, the authors review their treatment proposals, based on the integration of brain training techniques and biobehavioral interventions. Somatosensory reintegration (tactile acuity training), facial emotion recognition, movement representation techniques, orofacial motor training and therapeutic patient education are explained in detail, and this may challenge new directions in rehabilitation and research.
Nomophobia among medical students and its association with depression, anxiety, stress and academic performance

Abstract: Introduction: As the world becomes increasingly interconnected, the adoption of technology remains one of the defining factors of human progress. Nomophobia (NO MObile PHOne PhoBIA) represents a mental condition caused by the fear of being detached from mobile phone connectivity. Such condition is directly associated with depression, anxiety, and stress. Moreover, nomophobia can lead to structural brain damage. Objective: The present study aims to assess the effect of nomophobia on medical students at a private institution and its association with depression, anxiety, stress and academic performance. Method: This is a cross-sectional observational study carried out in medical students at Centro Universitário Christus. Nomophobia was measured using the Nomophobia Questionnaire (NMP-Q). The NMP-Q has 20 questions, which are asked on a 7-point Likert scale. This scale has been validated for the Brazilian Portuguese language. Depression, anxiety and stress were measured by the DASS-21, a simplified version of the DASS instrument. The DASS-21 questionnaire was also validated for the Brazilian Portuguese language. Academic performance was measured through API, the product of a complex mathematical operation that results in the student’s average grade in the semester and functions as a reference index for pedagogical follow-up in the assessed institution. In addition, the device use habits were assessed. Descriptive results were presented, and bivariate analyses of association and correlation were performed. This study was approved by the research ethics committee. Result: A sample of 292 students was assessed. Virtually all students (99.7%) had some degree of nomophobia, and 64.5% had a moderate or severe level of nomophobia. More than 50% of the students had higher than mild degrees of stress, and 19.5% and 11.2% of the students had severe or very severe levels of anxiety and depression, respectively. When analyzing the correlation of NMP-Q with DASS-21 scores, it was observed that increases in NMP-Q lead to increases in the overall DASS score (p < 0.001), and that worse results in DASS-21 are associated with worse API. Conclusion: Our study suggests that nomophobia is likely to increase anxiety, stress and depression and, as a result, leads to a decrease in academic performance.
Pembiayaan Pasien COVID-19 dan Dampak Keuangan terhadap Rumah Sakit yang Melayani Pasien COVID-19 di Indonesia Analisis Periode Maret 2020 – Desember 2020

Rendahnya kunjungan pasien selama pandemi COVID-19 berakibat turunnya pendapatan rumah sakit secara drastis. Beban rumah sakit yang menangani pasien COVID-19 semakin tinggi dengan adanya keterlambatan pembayaran klaim COVID-19. Kajian ini bertujuan untuk menjelaskan kebijakan pembiayaan COVID-19 di rumah sakit, kendala dari pelaksanaan kebijakan, serta dampaknya pada keuangan rumah sakit di Indonesia. Kajian bersifat deskriptif analitik, pengumpulan data dilakukan melalui penelusuran literatur dari jurnal ilmiah, BPJS Kesehatan, Kementerian Kesehatan, Asosiasi Rumah Sakit, maupun seminar ilmiah di media massa daring. Data BPJS per tanggal 28 Januari 2021 menunjukkan total pengajuan klaim COVID-19 oleh rumah sakit sebanyak 433.077, dari hasil verifikasi tercatat sebanyak 266.737 kasus yang sesuai (61,59%) dan dapat diklaim dengan biaya 17,3 triliun, 165.189 kasus dispute (38,14%) dengan biaya 9,7 triliun dan 1.151 kasus tidak sesuai (0,27%). Total klaim yang diajukan sampai Desember 2020 sebesar Rp. 22.9 triliun, jumlah yang sudah dibayarkan Kementerian Kesehatan kepada rumah sakit sebesar Rp. 14.5 triliun (63.3%) dan sisa yang belum dibayarkan sebesar Rp. 8.4 triliun (36,6%). Kendala yang ditemui dalam pembayaran klaim antara lain; pembayaran tidak tepat waktu, tingginya dispute klaim yang disebabkan perbedaan persepsi terhadap regulasi yang berlaku, dokumen klaim rumah sakit yang tidak lengkap, ketidaksiapan perangkat aplikasi dan jumlah verifikator dispute dari Kementerian Kesehatan dalam melakukan proses verifikasi ulang. Penurunan arus kas mengakibatkan terjadinya hambatan operasional rumah sakit, antara lain penurunan kemampuan kewajiban membayar penyedia obat dan alat kesehatan, termasuk pembayaran gaji tenaga kesehatan dan karyawan rumah sakit.
Associated atmospheric mechanisms for the increased cold season precipitation over the Three-River Headwaters region from the late 1980s

Precipitation in the Three-River Headwater (TRH) region has undergone significant changes as a result of global warming, which can affect water resources in downstream regions of Asia. However, the underlying mechanisms of the precipitation variability during the cold season (October to April), are still not fully understood. In this study, the daily China gridded precipitation product of CN05.1 as well as the NCEP-NCAR reanalysis are used to investigate the characteristics of the cold season precipitation variability over the TRH region and associated atmospheric mechanisms. The cold season precipitation shows an increasing trend (5.5 mm decade-1) from 1961 to 2014, with a dry-to-wet shift in around the late 1980s. The results indicate that the increased precipitation is associated with the enhanced easterly anomalies over the Tibetan Plateau (TP) and enhanced southeasterly water vapor transport. The enhanced Walker circulations, caused by the gradients of sea surface temperature between the equatorial central-eastern Pacific and Indo-western Pacific in tropical oceans, resulted in strengthened easterly anomalies over the TP and the westward expansion of the anticyclone in the western North Pacific. Meanwhile, the changed Walker circulation is accompanied by a strengthened local Hadley circulation which leads to enhanced meridional water vapor transport from tropical oceans and the South China Sea toward the TRH region. Furthermore, the strengthened East Asia Subtropical Westerly jet may contribute to the enhanced divergence at upper level and anomalous ascending motion above the TRH region leading to more precipitation.
A shift to shorter cuticular hydrocarbons accompanies sexual isolation among Drosophila americana group populations

Because sensory signals often evolve rapidly, they could be instrumental in the emergence of reproductive isolation between species. However, pinpointing their specific contribution to isolating barriers, and the mechanisms underlying their divergence, remains challenging. Here, we demonstrate sexual isolation due to divergence in chemical signals between two populations of Drosophila americana (SC and NE) and one population of D. novamexicana, and dissect its underlying phenotypic and genetic mechanisms. Mating trials revealed strong sexual isolation between Drosophila novamexicana males and SC Drosophila americana females, as well as more moderate bi‐directional isolation between D. americana populations. Mating behavior data indicate SC D. americana males have the highest courtship efficiency and, unlike males of the other populations, are accepted by females of all species. Quantification of cuticular hydrocarbon (CHC) profiles—chemosensory signals that are used for species recognition and mate finding in Drosophila—shows that the SC D. americana population differs from the other populations primarily on the basis of compound carbon chain‐length. Moreover, manipulation of male CHC composition via heterospecific perfuming—specifically perfuming D. novamexicana males with SC D. americana males—abolishes their sexual isolation from these D. americana females. Of a set of candidates, a single gene—elongase CG17821—had patterns of gene expression consistent with a role in CHC differences between species. Sequence comparisons indicate D. novamexicana and our Nebraska (NE) D. americana population share a derived CG17821 truncation mutation that could also contribute to their shared “short” CHC phenotype. Together, these data suggest an evolutionary model for the origin and spread of this allele and its consequences for CHC divergence and sexual isolation in this group.
