Students’ Approaches toward the Visual Arts Course Using Elements of Popular Culture

This study aims to identify students’ approaches toward courses lectured by visual arts teachers with elements of popular culture with a view to enabling students to attain 7th grade targeted achievements. To this end, the multiple-case design, one of the qualitative research methods, was utilized in the study. The sample of the study comprised 11 visual arts teachers working at secondary schools located in three central districts of the Bursa province of Turkey. As the data collection tools, two interview forms and document review were used. The obtained findings were evaluated through the thematic analysis technique and were compiled under the theme of ‘implications on students’. As per the research results, it was discerned that there were certain differences in the students’ approaches toward the course along with employment of elements of popular culture in the visual arts course. It may be alleged that, of these differences, the primary ones were attraction of students’ attention to the course, active participation into the course and facilitation of comprehension.
Creation of a Model for Estimating the Home-return Rate of Evacuees Using Mobile Phone Movement Histories and Its Application to the Nankai Trough Earthquake

Considering the 2011 Great East Japan Earthquake, by utilizing GPS based large-scale people flow data, we developed a home-return model considering city variables that can estimate the rate of people who will have returned home on any number of days after an earthquake tsunami disaster. We obtained high accuracy with the sparse logit model in this study. The model can be applied in estimating a disaster only by using grid-based city variables of GIS data and existing damage estimation models. In addition, we used the model in the case of the Nankai Trough megathrust earthquake and simulated the transition of postdisaster home-return ratio. The estimation result can help local governments plan the management of evacuation centers in terms of the management of supplies and goods for disasters. The study could help a new understanding of the quantitative relationship between people returning home after evacuation and city variables with regard to earthquake and tsunami hazards based on spatial infor-
Teleseismic Tomography of the Laguna del Maule Volcanic Field in Chile

With substantial postglacial rhyolite eruptions and ongoing rapid uplift, the Laguna del Maule volcanic field in the southern Andes provides an exceptional opportunity to study the dynamics of an active silicic magmatic system. Using 4,093 P arrivals from 137 distant earthquakes recorded by 44 local stations over ∼2.25 years, we conduct teleseismic tomography to image the crustal structure down to 40 km below the volcanic field. A prominent low‐velocity body at depths between ∼0 and 12 km below sea level (b.s.l.), characterized by a volume of ∼500 km3 and a peak anomaly of −400 m/s (∼9%), overlaps the location of the upper‐crustal magma reservoir detected in recent gravity and surface wave tomography studies. Its estimated average P wave velocity of ∼4.6 km/s corresponds to an average melt fraction of about 14% and a melt volume of ∼70 km3. Petrologic observations are also consistent with generation and storage of rhyolitic melts at depths corresponding to the anomalous zone. Moreover, the tomographic results support a lower crust zone of MASH (melting, assimilation, storage, and homogenization) from a depth of ∼25 km to the base of the model, which likely reflects a deep crustal source of magma that contributes to and incubates the shallow silicic reservoir.
How regulation on environmental information disclosure affects brownfield prices in China: a difference-in-differences (DID) analysis

Studies have shown that brownfields are often sold at a discounted price to compensate for anticipated clean-up costs and potential liability risk. However, such a hypothesis has not been tested in the Chinese context, largely due to a lack of information about land contamination and the absence of regulations regarding brownfields. Over the past decade, Chinese cities’ gradual introduction of redevelopment policies for former industrial sites has increased public awareness regarding land contamination. In Shanghai, the land market has responded to regulations on mandatory environmental information disclosure at land auctions. Using Shanghai land transaction data from 2007 to 2019, we examine the temporal response of land markets to environmental policy changes by employing several difference-in-differences regression models. The results show that brownfield parcels had been sold for prices 18% lower than greenfields, and that such discounts tend to become more significant after at least three years of policy implementation.
THE IMPLEMENTATION OF COMMUNITY ENGAGEMENT IN PUBLIC SERVICE DELIVERY IN THE UK AND POLICY IMPLICATION TO VIETNAM

This paper explores how community engagement is implemented by the third sector organisation in public service delivery in the UK. This research applied a case-study approach involving two third sector organisations involved in public service delivery in the UK. The study’s findings revealed community engagement as an important aspect in public service delivery that fosters social cohesion and social capital and thus, the implementation of community engagement needs attention to stakeholders’ interaction, social network, and capability. The results are discussed in relation to the implications for policy, especially in relation to frameworks that can support public value enhancement.
Workspace Enlargement of Cable-Based Haptic Device Using Linear Actuator

Haptic displays have been attracting attention for several decades and a broad range of devices have been developed to allow interaction with virtual objects. Among these, cable-based architectures were researched in order to overcome the lack of ﬂexibility and the intrusiveness inherent to rigid haptic displays. Cable robots allow the utilization of several end effectors, which can be proved to be particularly useful for providing haptic rendering on several ﬁngers for the bimanual manipulation of virtual objects. Nonetheless, interference can appear when cables touch each other during manipulation. Also, some conﬁgurations may require a high number of cables to make full use of the frame of the device. Here, we propose a novel architecture of a haptic display based on SPIDAR. Our purpose is to enlarge the usable workspace of an existing device conﬁguration while lowering the number of cables and without hindering the quality of the display. A hybrid planar haptic device architecture with n+1 cables that includes a linear module is introduced. Design considerations and the kinematics used are detailed. Then, simple tasks are performed to verify the usability of the device as a haptic display.
Application strategies of saline water and nitrogen doses in mini watermelon cultivation

Salt stress is highlighted as one of the limiting factors for the establishment of agriculture in the semiarid region of Northeastern Brazil. In this context, it is essential to look for new strategies aiming at minimizing the effects of salt stress on the crops. The present work aimed to evaluate the photochemical efficiency, photosynthetic pigments, and growth of the watermelon cv. Sugar Baby under different use strategies with saline waters and nitrogen fertilization. The experiment was conducted in a protected environment at the Center of Technology and Natural Resources of the Federal University of Campina Grande, municipality of Campina Grande, Paraiba. An experimental design in randomized blocks was adopted, arranged in a 6 x 2 factorial scheme, with six management strategies of water salinity and two nitrogen doses (corresponding to 50 and 100% of the recommendation), with five replications. Two salinity levels of the irrigation water were studied, one with low and another with a high level of electrical conductivity of the water (ECw = 0.8 and 3.2 dS m-1). The watermelon cv. Sugar Baby expressed higher sensitivity to salt stress in the flowering phase, with a decrease in the synthesis of chlorophyll b, chlorophyll total, and carotenoids. The 50% dose of N provided an increment in the initial fluorescence, stem diameter, and the number of leaves of the watermelon cv. Sugar Baby. The length of the main branch of the watermelon plants decreased with the salt stress applied in the fructification phase; however, the fertilization with 100% of N stimulated a higher growth when the irrigation with saline waters was performed at the vegetative and flowering phases.
Confocal scanning of intervertebral disc cells in 3D: Inside alginate beads and in native microenvironment

The interaction between cells and their extracellular matrix (ECM) is crucial to maintain both tissue and cellular homeostasis. Indeed, cell phenotype is significantly affected by the 3D microenvironment. Although highly convenient, isolating cells from the intervertebral disc (IVD) and growing them in 2D on plastic or glass substrates, causes them to rapidly lose their phenotype and consequently alter their gene and protein expression. While characterization of cells in their native or simulated 3D environment is preferred, such approaches are complexed by limitations in phenotypic readouts. In the current article, we describe a detailed protocol to study nucleus pulposus cells in 3D—embedded in alginate as a permeable cell‐staining reservoir, as well as adaptation for cell staining and imaging in their native ECM. This method allows for detection of phenotypical and cytoskeletal changes in cells within native tissue or 3D alginate beads using confocal microscopy, without the need for histological processing.
Transformations from standard photometric systems to the Gaia passbands

Aims. Provide a transformation from the standard photometric filters to Gaia G, GBP and GRP passbands. Methods. The relations between the standard photometric filters in the Johnson-Cousins UBV RC IC photometric system, the SDSS ugriz system, and the Gaia passbands were fitted with up to third order polynomials for dwarfs and giants individually. Results. At least for the Gaia GBP passband the Johnson-Cousins filter are better suited for a reliable prediction. No improvement is seen for higher than third order polynomial fits for any of the performed transformations. Conclusions. The provided dependencies amongst colours can be used to transform the apparent magnitudes in the B, V, RC , and SDSS griz passbands to Gaia G, GBP , and GBR photometry, allowing for a comparison of the Gaia survey to models of the Galaxy and to previous large surveys.
Route planning for blind pedestrians using OpenStreetMap

While most of us take wayfinding and orientation for granted, instinctively utilizing our visual channels to do so, millions of blind people around the world face challenges and obstacles when attempting to perform the most basic tasks, such as walking to the corner store or using public transportation. As blind pedestrians lack critical information about the space they traverse outside the familiarity of their home, they are restricted, dependent on others, and have decreased quality of life. While assistive technologies for providing specific navigation solutions do exist, research is still limited regarding customized wayfinding solutions for blind pedestrians. This research aims at developing a wayfinding algorithm that relies on the OpenStreetMap mapping catalogue for planning accessible and safe routes specifically suited to blind pedestrians. In-depth investigations, observations, and interviews were conducted with blind people and with orientation and mobility instructors, in order to define and categorize spatial criteria relating to mobility, accessibility, and safety. Using controlled iterative experiments, weighted network graph criteria were defined, leading to the development of a route planning software that generates optimized routes for blind pedestrians. The developed software was then tested on a variety of routes, with the help of blind volunteers and orientation and mobility instructors. The results show that the optimal routes generated by the software were identical or very similar to those suggested by the experienced orientation and mobility instructors. Moreover, the blind volunteers also stated that the software planned routes were indeed more accessible and safer for them to walk along compared to routes suggested by existing commercial software developed for seeing pedestrians. The findings of this research indicate that our solution, based on OpenStreetMap and developed for the benefit of blind pedestrians, is effective and practical, and could improve the mobility, independence, and quality of life of this population, as well as increasing their integration into society.
SPONTANEOUS OR PROGRAMMATIC? LAND OCCUPATIONS DURING SPAIN'S SECOND REPUBLIC (1931–1936)

ABSTRACT This paper studies the spatial deployment of temporary settlements in Extremadura in 1932-1933 and 1936. The literature has stressed the role of bottom-up forces driving settlements in 1933 and 1936, perhaps making land reform in Extremadura an interesting case study of local collective action-driving policy implementation in a developing economy. Contrary to this view, we argue that there was an equal or more important role of the top-down, programmatic design of land occupations, which explains a large share of the spatial and temporal variation of expropriations and settlements.
Phase equilibria of “Cu2O”-“FeO”-SiO2-CaO slags at PO2 at 10-8 atm in equilibrium with metallic copper

Limited data are available on phase equilibria of the “Cu2O”-“FeO”-SiO2-CaO slag system at the oxygen partial pressures used in the copper smelting, converting and slag cleaning processes. Recently experimental procedures have been developed and have been successfully applied to characterise a number of complex industrial slags. The experimental procedures involve high temperature equilibration on a primary phase substrate and rapid quenching of the sample followed by the electron probe X-ray microanalysis. This technique has been used to construct the liquidus isotherms in the “Cu2O”-“FeO”-SiO2-CaO slag system in equilibrium with copper. The liquidus isotherms and solubilities of copper oxide in liquid slags at the controlled oxygen partial pressure of 10 atm and temperatures between 1150 and 1350 C have been determined in equilibrium with metallic copper and the tridymite, olivine, wustite, wollastonite or pseudo-wollastonite solid phases. The new experimental data on copper solubility in slag at different temperatures have been analysed using a regular solution model to describe the activity coefficients of copper oxide as a function of temperature and liquid slag composition. The new experimental equilibrium results are presented in the form of ternary sections and the effects of slag composition on the calculated activity coefficients of liquid CuO0.5 in slag are reported. The activity coefficient γCuO0.5 is shown to significantly increase with increasing CaO/SiO2 and Fe/SiO2 weight ratios.
Applying Comparable Sales Method to the Automated Estimation of Real Estate Prices

In this paper, we propose a novel procedure designed to apply comparable sales method to the automated price estimation of real estates, in particular, that of apartments. Apartments are the most popular residential housing type in Korea. The price of a single apartment is influenced by many factors, making it hard to estimate accurately. Moreover, as an apartment is purchased for living, with a sizable amount of money, it is mostly traded infrequently. Thus, its past transaction price may not be particularly helpful to the estimation after a certain period of time. For these reasons, the up-to-date price of an apartment is commonly estimated by certified appraisers, who typically rely on comparable sales method (CSM). CSM requires comparable properties to be identified and used as references in estimating the current price of the property in question. In this research, we develop a procedure to systematically apply this procedure to the automated estimation of apartment prices and assess its applicability using nine years’ real transaction data from the capital city and the most-populated province in South Korea and multiple scenarios designed to reflect the conditions of low and high fluctuations of housing prices. The results from extensive evaluations show that the proposed approach is superior to the traditional approach of relying on real estate professionals and also to the baseline machine learning approach.
The Effect of Facilitative Versus Inhibitory Word Training Corpora on Word Reading Accuracy Growth in Children With Dyslexia

We modeled word reading growth in typically developing (n = 118) and children with dyslexia (n = 20), Grades 2–5, across multiple exposures to 30 words. We explored the facilitative versus inhibitory effects of exposures to differential mixes of words that support high- versus low-frequency vowel pronunciations. One training corpus contained a ratio of 80%–20% high- to low-frequency pronunciations (e.g., for ea; 80% ea pronounced as /i/ as in bead and 20% ea pronounced /ε/ as in dead), whereas the other consisted of a ratio of 20%–80%. We also modeled accuracy at the final exposure for a subset of 12 shared words across conditions using item-level crossed-random effects models with reading skill (i.e., typically developing vs. dyslexic), condition, word frequency, and vowel pronunciation (i.e., high- vs. low-frequency vowel pronunciation) as predictors in the model. We were particularly interested in the interaction between condition and vowel pronunciation across reading groups. Results suggest typically developing children were influenced by the interaction between condition and vowel pronunciation, suggesting both facilitation and inhibition, whereas children with dyslexia were influenced by condition and vowel pronunciation without an interaction. Results are interpreted within the overfitting model of dyslexia.
A Framework for Offering Short-Term Demand-Side Flexibility to a Flexibility Marketplace

The decarbonization of the power sector involves electrification and a massive deployment of variable renewable energy sources, leading to an increase of local transmission congestion and ramping challenges. A possible solution to secure grid stability is local flexibility markets, in which prosumers can offer demand-side flexibility to the distribution system operator or other flexibility buyers through an aggregator. The purpose of this study was to develop a framework for estimating and offering short-term demand-side flexibility to a flexibility marketplace, with the main focus being baseline estimation and bid generation. The baseline is estimated based on forecasts that have been corrected for effects from earlier flexibility activations and potential planned use of internal flexibility. Available flexibility volumes are then estimated based on the baseline, physical properties of the flexibility asset and agreed constraints for baseline deviation. The estimated available flexibility is further formatted into a bid that may be offered to a flexibility marketplace, where buyers can buy and activate the offered flexibility, in whole or by parts. To illustrate and verify the proposed methodology, it was applied to a grocery warehouse. Based on real flexibility constraints, historic meter values, and forecasts for this use-case, we simulated a process where the flexibility is offered to a hypothetic flexibility marketplace through an aggregator.
Building Security through Insecurity: The Nigerian Military and Counter-Violence Campaigns in the Fourth Republic

Since independence on October 1, 1960, Nigeria has been a victim, at one time or the other, of intra-ethnic, inter-ethnic, religious, and communal conflicts which have undermined the human security of her citizens. Nigeria’s corporate existence had also been threatened by 3 years (1967–1970) civil war which impacted negatively on the well-being of its people. In addition, the inability of the Nigerian Police to cope with the magnitude of the surge of violence in recent years has brought about the idea of involving the military, a core component of traditional security apparatus to deal with internal insecurity. This article is anchored on human security paradigm with reliance on secondary data to analyze the operations of the Nigerian Military in counterviolence campaigns between 1999 and 2017. This article points out that the involvement of the military in internal security has worsened the problem of insecurity due to the military’s unprofessional approach and, at times, deliberate targeting the civilian populace which it is supposed to protect. It, therefore, recommends among others, the need for the Federal Government of Nigeria to urgently review the role of the armed forces in addressing internal security situations in a way that will bring about respect for the rule of engagement in internal security operations and adherence to global best practices.
Brief Research Report: Notes on a Nonparametric Estimate of Effect Size

Abstract Researchers are encouraged to report effect size statistics to quantify treatment effects or effects due to group differences. However, estimates of effect sizes, most commonly Cohen’s d, make assumptions about the distribution of data that are not always true. An alternative nonparametric estimate of effect size, relying on the median absolute deviation, is proposed. Comparison of this estimate to Cohen’s d using (simulated) non-normally distributed data demonstrate that the nonparametric approach effect size may be a better estimate of effect size.

Synthesis, Biological Evaluation and Docking Studies of Some New Indolyl-Pyridine Containing Thiazolidinone and Azetidinone Analogs

Abstract A novel series of Schiff base indolyl-pyridine derivatives containing, thiazolidinone and azetidinone moieties were synthesized. The structure of these recently integrated compounds was asserted by their IR, 1H, 13C NMR, mass spectral data as well as elemental analysis. These compounds were likewise evaluated for in vitro antimicrobial, antioxidant, anti-TB and anticancer activities. The structure-activity relationships of compounds were also established. Among which compound 4a has dynamic bactericidal activity against S. aureus and B. subtilis, compound 5a applied extraordinary action against E. coli and K. pneumonia and fungicidal activities. Antioxidant studies revealed that 4c, 5 b and 5e showed noteworthy antioxidant activities. While, anticancer movement demonstrated that compound 4e was most strong toward all attempted cancer cell lines. Compound 5e apparently was generally powerful against H37Rv strain M. tuberculosis. Further, to understand the binding modes of the incorporated compounds molecular docking contemplates were performed using crystal structure of mycobacterium smegmat complexed with SQ109 (PDB ID: 6AJG, resolution: 2.604 Å).
