Portal Active learning about climate change

We develop a climate-economy model with active learning. We consider three ways of active learning: improved observations, adding observations from the past and improved theory from climate research. From the model, we find that the decision maker invests a significant amount of money in climate research. Expenditures to increase the rate of learning are far greater than the current level of expenditure on climate research, as it helps in taking improved decisions. The optimal carbon tax for the active learning model is nontrivially lower than that for the uncertainty model and the passive learning model. JEL classification: Q54
Evaluation of teachers’ knowledge about dental injuries in primary schoolchildren in the city of Isfahan

Background: Dental trauma is a common problem in children, which mostly occurs at school. Traumatic dental injuries often cause unpleasant experiences for children, and immediate and appropriate measures are needed. Its prognosis depends on immediate posttraumatic measures, and schoolteachers can play a key role in the treatment of children. The current study aimed to investigate teachers’ knowledge about dental injuries in primary school children in the city of Isfahan. Materials and Methods: Following a cross-sectional design, the current study was conducted on 248 elementary school teachers who were selected using the simple two-stage random cluster. Then the teachers’ knowledge was measured based on a four-choice questionnaire consisted of two parts. According to this questionnaire, teachers were divided into five categories based on their knowledge score which was consist of strongly high knowledge, high knowledge, average knowledge, low awareness, and strongly low knowledge. Data were analyzed using the Spearman correlation coefficient and independent t-test. Statistical significance was considered when P < 0.05. Results: The total knowledge score of teachers was 45.9%. About 61% of the teachers had a history of exposure to dental injuries. Furthermore, 49.6% of them believed milk was the best environment to keep the avulsed teeth. There was no significant association between teachers’ knowledge and education level, history of previous trauma, or participation in a training course, but there was a direct association between teachers’ knowledge and their work experience (P < 0.05). Female teachers’ knowledge score was significantly higher than their male counterparts (P < 0.001). Conclusion: Participants had a moderate level of knowledge about the management of dental traumas. Hence, it is suggested to develop educational programs to increase teachers’ awareness about this issue.
Adaptive Driving Beam Headlights: Visibility, Glare and Measurement Considerations

Recent developments in solid-state lighting, sensor and control technologies are making new configurations for vehicle forward lighting feasible. Building on systems that automatically switch from high- to low-beam headlights in the presence of oncoming vehicles, adaptive driving beam (ADB) systems can detect both oncoming headlights and preceding taillights and reduce their intensity only in the direction of the other lights while maintaining higher levels of illumination throughout the remainder of the field of view. The nominal benefit of ADB systems is the provision of high-beam levels of illumination in the forward scene while reducing glare to oncoming and preceding drivers, who perceive low-beam illumination levels. Two dynamic field experiments were conducted; one experiment measured the ability of observers to identify the walking direction of roadside pedestrian targets with and without using the ADB system, and the other experiment evaluated the discomfort glare elicited by the ADB system in comparison to conventional low- and high-beam headlights. The findings from both experiments are consistent with previous analytical and static field tests and suggest that ADB systems can offer safety benefits compared to conventional headlight systems. Despite these potential benefits, ADB systems are not presently defined in North American headlighting standards. Field measurements of the photometric performance of an adaptive driving bean system were made in response to simulated headlight and tail light conditions. Roadway geometries were varied and multiple measurements for many conditions were made to assess repeatability of measurements. The results of the testing are summarized in the context of validating the likely safety impacts of these systems and of providing recommendations for standardized measurement conditions to ensure reliability.
Vitamin C and E supplementation hampers cellular adaptation to endurance training in humans: a doubleblind, randomised, controlled trial

In this double-blind, randomised, controlled trial, we investigated the effects of vitamin C and E supplementation on endurance training adaptations in humans. Fifty-four young men and women were randomly allocated to receive either 1000 mg of vitamin C and 235 mg of vitamin E or a placebo daily for 11 weeks. During supplementation, the participants completed an endurance training programme consisting of three to four sessions per week (primarily of running), divided into high-intensity interval sessions [4–6 × 4–6 min; >90% of maximal heart rate (HRmax)] and steady state continuous sessions (30–60 min; 70–90% of HRmax). Maximal oxygen uptake (V̇O2max), submaximal running and a 20 m shuttle run test were assessed and blood samples and muscle biopsies were collected, before and after the intervention. Participants in the vitamin C and E group increased their V̇O2max (mean ± S.D.: 8 ± 5%) and performance in the 20 m shuttle test (10 ± 11%) to the same degree as those in the placebo group (mean ± S.D.: 8 ± 5% and 14 ± 17%, respectively). However, the mitochondrial marker cytochrome c oxidase subunit IV (COX4) and cytosolic peroxisome proliferator-activated receptor-γ coactivator 1 α (PGC-1α) increased in the m. vastus lateralis in the placebo group by 59 ± 97% and 19 ± 51%, C © 2014 The Authors.

Furthermore, mRNA levels of CDC42 and mitogen-activated protein kinase 1 (MAPK1) in the trained muscle were lower in the vitamin C and E group than in the placebo group (P 0.05). Daily vitamin C and E supplementation attenuated increases in markers of mitochondrial biogenesis following endurance training. However, no clear interactions were detected for improvements in V̇O2max and running performance. Consequently, vitamin C and E supplementation hampered cellular adaptations in the exercised muscles, and although this did not translate to the performance tests applied in this study, we advocate caution when considering antioxidant supplementation combined with endurance exercise.

Effects of Virtual Map Navigation Mode on Route Retracing

Abstract Virtual maps for navigation are commonly categorized as either allocentric perspective maps or egocentric perspective maps, depending on the frame of reference. Route retracing means finding one’s way back from the destination to the origin. A 2 (navigation mode: allocentric/egocentric mode) × 2 (retracing mode: allocentric/egocentric mode) × 2 (gender) mixed design was implemented in this study to investigate how virtual map navigation modes affect route retracing performance in navigation. Participants’ performances in route retracing, ranked from the best to the worst, were in allocentric-allocentric, egocentric-allocentric, egocentric-egocentric, and allocentric-egocentric modes. The study demonstrated that the results mentioned above can be explained by the effect of the allocentric retracing mode and the consistency effect of the navigation-retracing mode. Females were more affected by these two effects than males, and gender differences disappeared in the allocentric-allocentric mode.
Efficiency of using Different Organic Manures on Growth, Yield and Quality of Strawberry through Various Planting Media

In recent times application of chemical fertilizers is one of the more concerned topics to sustainable and ecofriendly production. The reduction of cultivable lands day by day is another thoughtful issue. Application of different organic manures is an ecofriendly and safer crop production techniques as well as beneficial for soil health. Planting of strawberry in polybags could be a cheaper way of verticultural production (practice of growing strawberries in vertically stacked layers) and overcome the land deficit problems. Considering the mentioned topics, the present experiment was undertaken to evaluate the efficiency of using different organic manures (cowdung, mustard oil cake, poultry manure) on growth, yield and quality of strawberry through various planting media (Planting of strawberry saplings on soil and polybags). The experiment was conducted at Landscaping Section of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period from October 2019 to April 2020. Significant variations were observed due to planting media and organic manures on all growth, yield and quality parameters. Highest fruit length (3.43 cm), breadth of fruits (2.54 cm), Total soluble solids (7.44%), total fruit weight per plant (213.88 g) and total yield (12.80 ton.ha-1) were obtained from planting of strawberry plants in polybags in comparison with planting in soil. In case of organic manures superior data of length of fruits (4.27), breadth of fruits (3.21), total soluble solids (8.10%), total fruit weight per plant (272.50) and yield (16.35 ton.ha-1) were found from mixture application of organic manures instead of single applications.

The antibacterial efficiency of dental powder, toothpastes, mouth rinses, charcoal, table salt and chewing sticks against Streptococcus and Lactobacillus acidophilus

Chewing sticks and other means of obtaining oral health are widely used throughout Africa. But how does the usage of materials compare to the conventional use of fluoride toothpastes for oral hygiene? The aim of the study was to comparatively evaluate the antibacterial efficacy of traditional oral care practices (chewing sticks, dental powders, mouth washes, table salt, and charcoal) and conventional toothpaste against two bacteria strains of public health significance. Standard microbiological and analytical methods were used. Lactobacillus acidophilus ATCC 314TM and Streptococcus mutans ATCC 25175were obtained from the American Type Culture Collection Centre and appropriately reactivated. The stem cuttings of chewing stick (Zanthoxylum zanthoxyloides and Massularia acuminata) were extracted using Soxhlet apparatus. Antibacterial activity of the extracts were done using a modified Kirby-Bauer disk diffusion technique, the minimum inhibitory concentration and minimum bactericidal concentration were carried out using micro dilution technique of double fold dilution. Antibacterial susceptibility testing was done and multiple antibiotic resistance index of the bacterial strain was evaluated thereafter. The results showed that the toothpaste sample labelled B had the highest zone of inhibition (18.00±0.10 cm) and (21.00±0.87 cm) in at a 100% concentration for L. acidophilus and S. mutans respectively. The two chewing stick samples used in the study had antibacterial activity at 100 % concentration for both strains. The mouthwash used in the study tend to have the highest antibacterial activity against S. mutans and L. acidophilus having a diameter (mm) zone of inhibition 26.00±0.20 cm and 24.00±0.95 cm at 100 % concentration respectively. Mouth wash sample met the Clinical Laboratory Standard Institute criterion for reporting the result as sensitive ≥20. Gentamicin, Cefazidime and Meropenem were sensitive to both S. mutans ATCC®25175 and L. acidophilus ATCC®314. Both bacterial strains used in the study had an index greater than 0.2 which symbolizes that they are of public health importance.
Can Early Environmental Enrichment Buffer Stress from Commercial Hatchery Processing in Laying Hens?

Under commercial conditions, laying hen chicks are exposed to a range of stressful events immediately after hatch. Here, we studied whether environmental enrichment was able to reduce the stress sensitivity of these chicks. A total of 50 hatchery chicks (HC) and 50 control chicks (CC) were raised in enriched pens (E), while 53 HC + 53 CC were raised in standard non-enriched floor pens (NE). HC weighed less on day one, but there was no effect of hatchery treatment at later ages. HC were more pessimistic in a cognitive judgement bias test and emitted more distress calls when socially isolated, indicating that hatchery stress affected behaviour and stress sensitivity. However, enrichment did not affect the behaviour in any of these tests. We found no effects of hatchery stress in a novel environment, but indications that enrichment may have increased fearfulness of HC. The sensitivity of the hypothalamic-pituitary-adrenal (HPA) axis was reduced in HC-E compared to HC-NE, indicating that enrichment buffered the physiological stress sensitivity in HC; however, the opposite pattern was found in CC. In conclusion, our results show complex and somewhat contradictory effects on the ability of enrichment to buffer the consequences of stress in commercial hatcheries.
Assessment of visual comfort in the lighting environments of subway cabins in China

ABSTRACT This paper presents a multi-dimensional evaluation and comparison of the visual comfort of the cabin lighting environments of five subways lines in Chengdu. The study proposes a visual comfort evaluation procedure that integrates objective and subjective methods combined with existing visual comfort measurement methods. Based on this evaluation procedure, the lighting conditions (illuminance and glare) in each cabin were measured using an illuminance metre and high-dynamic image technology, and an online questionnaire was used to understand passengers’ subjective experiences of cabin lighting. The results show that: seating layout has no significant influence on the visual performance of mobile phones or on spatial brightness; horizontal illuminance in the lighting environments of subway cabins has no significant influence on task performance of passengers using mobile phones; the overall perception of subway cabin spatial brightness increases with vertical illuminance; and passengers have no obvious preference for a cabin correlated colour temperature.
Network Intrusion Detection Using Machine Learning Techniques

Intrusion detection systems (IDS) are essential for the protection of advanced communication networks. These systems were primarily designed to identify particular patterns, signatures, and rule violations. Machine Learning and Deep Learning approaches have been used in recent years in the field of network intrusion detection to provide promising alternatives. These approaches can discriminate between normal and anomalous patterns. In this paper, the NSL-KDD (Network Security Laboratory Knowledge Discovery and Data Mining) benchmark data set has been used to evaluate Network Intrusion Detection Systems (NIDS) by using different machine learning algorithms such as Support Vector Machine, J48, Random Forest, and Naïve Bytes with both binary and multi-class classification. The results of the application of those techniques are discussed in details and outperformed previous works.
Hybrid Seabed Parameterization to Investigate Geoacoustic Gradients at the New England Mud Patch

This article applies Bayesian geoacoustic inversion with a hybrid seabed-model parameterization to modal-dispersion data from the New England Mud Patch to estimate gradient structure in the upper mud layer. The hybrid parameterization comprises an upper layer with general smooth (continuous) gradients represented by Bernstein polynomials (BPs) for the mud, above an unknown number of discrete (uniform) layers. The Bayesian information criterion is applied to estimate BP orders for sound-speed and density profiles in the mud, and trans-dimensional (trans-D) inversion is applied for the underlying layered structure. The data, collected during the 2017 Seabed Characterization Experiment, include high-order modes (up to mode 21) extracted via warping time-frequency analysis from recordings of a combustive sound source at a vertical hydrophone array. Inversion results for the hybrid parameterization are compared to those from trans-D inversion with no gradient layer. Hybrid-inversion results indicate a nearly iso-speed mud layer with a rapidly increasing gradient near its base, consistent with increasing sand content in the mud above a sand interface, as indicated by cores. The sound-speed ratio of surficial sediments to bottom seawater is found to be $<$ 1 with high probability, which differs from trans-D inversion results, indicating the significance of the choice of parameterization in interpreting structure.
The opportunities and challenges of ICT in open and distance learning system with special reference to West Bengal

In a huge country like India Open and Distance Learning system of education emerges to provide quality education to a large number of learners. ODL is an area to address the fundamental issues of access, equity and quality of higher education to improve human capabilities and to achieve the vision of knowledge economy. ICT is playing an important role in ODL which was difficult to perform for the traditional system for its limited resources. Innovative use of ICT has completely revolutionized the conventional ODL system by reducing the cost and time of imparting education and introducing need based educational programmes to a large number of learners. In distance learning as students are remote to the institution, web based learning and student support services are required at different phases of student learning cycle and also for knowledge and information sharing as done in conventional system. In this paper the tremendous potentialities of ICT to serve all the purposes are discussed. However, there are some challenges and issues on its application in ODL set up which are also addressed.
Post-merger Employee Satisfaction in Commercial Banks of Nepal: Findings from Employee Satisfaction Index

Various mergers and acquisitions started in in Nepalese banking sector, since 2011 when Nepal Rastra Bank issued the merger by-law. This paper, therefore, aims to explore post-merger employee satisfaction of commercial banks in Nepal. Employees of Nepalese commercial banks are considered as population of the study. Hence, the sample of 310 commercial bankers is taken for the study. Result of the study revealed that employees of commercial banks (50 percent) are moderately satisfied, and post-merger and lack of effective communication were found to be the major challenges faced by most (65.16 percent) of the employees. However, 23 percent of the employees believed that if they were provided with proper training and development opportunities, they could mitigate challenges arising from post-merger activities. Therefore, the study concludes that banks should identify needs of employees and provide such an environment where they can work flexibly in the post[1]merger period.
