Published: February 2021

This paper decribes how the inequality of income distribution in the Province of North Sumatra Province is based on analysis interregional, namely the West Coast, Nias Islands, the Highlands, and the East Coast. The data analyzed is the Gini coefficient published by BPS North Sumatra Province from 2001 to 2016. Based on the distribution criteria of income from the Gini coefficient, there are three qualitative measures of inequality, viz: (1) relatively evenly distributed (very low inequality), (2) moderate inequality, (3) very high inequality. The results of data analysis show that: (1) there is no one regency or city whose income distribution is classified aa very high inequality, (2) all of regencies and cities in the highlands show a very low inequality, (3) in general, the distribution of income in regencies and cities in the West Coast, Nias Islands and the East Coast is relatively evenly distributed, (4) there is no clear pattern or fully unidirectional correlation between high economic growth rates and an increasingly unequal distribution of income in each regency or city. Very low inequality can also occur in regencies or cities whose economic growth rate are higher than the provincial economic growth rate. Vice versa, there are regencies or cities that have economic growth rates are lower than the provinces but instead show a moderate inequality.

Volcanoes in video games: the portrayal of volcanoes in commercial off-the-shelf (COTS) video games and their learning potential
Authors: McGowan Edward G. , Scarlett Jazmin P. 
Published: February 2021

Abstract. Volcanoes are a very common staple in mainstream video games. Particularly
within the action–adventure genres, entire missions (e.g. Monster Hunter: Generation Ultimate, 2018) or even full
storylines (e.g. Spyro: The Reignited Trilogy, 2018) can require players to traverse an active volcano.
With modern advancements in video game capabilities and graphics, many of
these volcanic regions contain a lot of detail. Most video games nowadays
have gameplay times in excess of 50 h. The Legend of Zelda: Breath of the Wild (2017), for example, brags a
minimum of 60 h to complete. Therefore, players can spend a substantial
amount of time immersed within the detailed graphics and unknowingly learn
about volcanic traits while playing. If these details are factually accurate
to what is observed in real-world volcanic systems, then video games can
prove to be a powerful learning tool. However, inaccurate representations
could instil a false understanding in thousands of players worldwide.
Therefore, it is important to assess the accuracies of volcanology portrayed
in mainstream video games and consider whether they can have an educational
impact on the general public playing such games or whether these volcanic
details are overlooked by players as they focus solely on the entertainment
factor provided. We have therefore reviewed several popular commercial video
games that contain volcanic aspects and evaluated how realistic said aspects
are when compared to real-world examples. It was found that all the games
reviewed had a combination of accurate and inaccurate volcanic features and
each would vary from game to game. The visual aesthetics of these features
are usually very realistic, including lava, ash fall and lahars. However,
the inaccuracies or lack of representation of hazards that come with such
features, such as ash-related breathing problems or severe burns from
contact with molten lava, could have great negative impacts on a player's
understanding of these deadly events. With further investigations assessing
the direct impact on the general public, there is an opportunity to
correctly assess how to incorporate the use of mainstream video games in
educational systems and outreach.
A regional spatiotemporal analysis of large magnitude snow avalanches using tree rings

Published: February 2021

Abstract. Snow avalanches affect transportation corridors and settlements worldwide. In many mountainous regions, robust records of avalanche frequency and magnitude are sparse or non-existent. However, dendrochronological methods can be used to fill this gap and infer historical avalanche patterns. In this study, we developed a tree-ring-based avalanche chronology for large magnitude avalanche events (size ≥∼D3) using dendrochronological techniques for a portion of the US northern Rocky Mountains. We used a strategic sampling design to examine avalanche activity through time and across nested spatial scales (i.e., from individual paths, four distinct subregions, and the region). We analyzed 673 samples in total from 647 suitable trees collected from 12 avalanche paths from which 2134 growth disturbances were identified over the years 1636 to 2017 CE. Using existing indexing approaches, we developed a regional avalanche activity index to discriminate avalanche events from noise in the tree-ring record. Large magnitude avalanches, common across the region, occurred in 30 individual years and exhibited a median return interval of approximately 3 years (mean = 5.21 years). The median large magnitude avalanche return interval (3–8 years) and the total number of avalanche years (12–18) varies throughout the four subregions, suggesting the important influence of local terrain and weather factors. We tested subsampling routines for regional representation, finding that sampling 8 random paths out of a total of 12 avalanche paths in the region captures up to 83 % of the regional chronology, whereas four paths capture only 43 % to 73 %. The greatest value probability of detection
for any given path in our dataset is 40 %, suggesting that sampling a
single path would capture no more than 40 % of the regional avalanche
activity. Results emphasize the importance of sample size, scale, and spatial extent when attempting to derive a regional large magnitude
avalanche event chronology from tree-ring records.
Overdose escalation and the pandemic: An urgent reminder to innovate Canada’s response to the opioid epidemic
Authors: Rusu Denisa 
Published: February 2021

A ‘dual crisis’ situation in Canada has gained more attention in the past two months, as deaths by overdose have reached record highs within the context of the COVID-19 pandemic overtaking the opioid epidemic. Given the already dire state of the prevailing overdose crisis (with no sustainable gains in improving mortality rates despite being declared a national emergency in 2016, expanded harm reduction and access to treatment), this acute spike is an urgent reminder of the unsustainability of the current system, in this case demonstrated by its inability to withstand stress.
Under this premise, this article reviews recent literature on possible factors contributing to the present surge in overdoses, with the aim of identifying pre-existing systemic issues exacerbated in the past months of pandemic response. Sociopolitical issues were found to be most contributory; specifically, legal restrictions to innovative, evidence-based approaches to harm reduction (i.e. “safe supply” programs and decriminalization of drug use) based in stigmatizing attitudes. An overview of potential ways these issues may be addressed by innovative initiatives (both current and proposed) is included. Advocacy leading to prompt expansion of such interventions may help address the alarming rise in opioid-related mortality during the COVID-19 pandemic and promote a more progressive and sustainable approach to the overdose crisis.
Remarks on Rule H
Authors: Drummond Alex 
Published: February 2021

Fox (2000) argues that a single principle, Rule H, can account for (i) Strong Crossover, (ii) the ban on using co-binding to sneak around Condition B, and (iii) the Dahl paradigm. The focus of this paper is Fox’s analysis of the Dahl paradigm. Though elegant and appealing, the analysis faces both conceptual and empirical problems. On the conceptual side, the analysis assumes that a bound pronoun within an elided VP must be bound in a structurally parallel configuration to its counterpart in the antecedent VP. This requirement does not follow from independently-motivated constraints on VP ellipsis. On the empirical side, Roelofsen (2011) has turned up additional ellipsis phenomena that do not pattern as Fox’s analysis predicts. I will argue that a relatively minor modification to Fox’s analysis suffices to solve both the conceptual and empirical problems. Taking inspiration from Kehler &amp; Büring (2008), I increase the domain of application of Rule H to include syntactic structures which underlie Focus Semantic Values, so that Rule H acts as a filter on Focus Semantic Values. The only relevant constraint on VP ellipsis is an independently-motivated Rooth-style contrast constraint.
Panorámica de la trilogía cine, historia y educación en España (1995-2020)
Authors: Fuentes-Moreno Concha , Ambrós-Pallarés Alba 
Published: February 2021

Se realiza una síntesis analítica de las principales líneas de trabajo que se han gestado en los últimos 25 años sobre el cine y el aprendizaje de la historia. Se revisa la literatura desde una perspectiva histórica mediante el uso de bases de datos, organizando las salidas en tres categorías. En la primera categoría, historia y cine, se agrupan las investigaciones relacionadas con la aceptación del cine como fuente histórica y como testimonio de una época. Una segunda categoría concentra los trabajos sobre historia, cine y educación, englobando las siguientes temáticas: cine y currículum escolar; cine de ficción y no ficción y cine como constructor de identidades. La tercera categoría se focaliza en el uso del cine en el aula de historia considerando aspectos didácticos relevantes. Los resultados demuestran que las recientes investigaciones reivindican el cine como instrumento de análisis y reflexión sobre el pasado como otra fuente histórica más, así como vía para fomentar el análisis crítico y empático propios de la competencia ciudadana. Del mismo modo, existe una tendencia que defiende la inclusión de la educación mediática y la alfabetización cinematográfica dentro de la educación formal y la formación inicial y permanente de todos los docentes.
The aim of the paper consists on an analytical synthesis of the main lines of research that have been developed in the last 25 years on the teaching of history with films. A systematic review of the literature inside databases from a historical perspective has been the followed methodology. The analysis has been structured in three categories. The first one, called history and cinema, evidences the existence of a research line focused on the acceptance of cinema as a historical source and also as witness of an Era. The second one relates history, films and education, and three more lines emerge from it: films and curriculum; fiction and non-fiction films, and using films as a constructor of identities. The third and last category is based on the use of films in the History classroom attending on methodological relevant aspects. The core results of the analysis point at two complementary directions. First, the vindication of films as a tool of analysis and reflection on the past as a historical source. Second, the acceptance of films as an instrument to promote critical and empathetic analysis of citizenship competence. Similarly, there is a trend that advocates the inclusion of media education and film literacy within formal education and the initial and ongoing training of all teachers.
Processes to enhance the sensitivity of sensor for 2‐n‐octyl‐4‐isothiazolin‐3‐one as biocide
Authors: Rhyu Seung Yeon , Cho Younghyun , Kang Sang Wook 
Published: February 2021

AbstractIn this study, hydraulic treatment was performed to fabricate porous cellulose acetate (CA) membranes for application as adsorbents for impurities. For this purpose, porous CA membranes were prepared by applying a water pressure of 8 bar on CA dissolved in a mixed solvent of acetone and water. These porous polymers could separate impurities from 2‐n‐octyl‐4‐isothiazolin‐3‐one (OIT) by providing adsorption surfaces for the suspended impurities and allowed pure OIT to filter through the membrane; the filtered OIT may subsequently be used for octyl‐group quantification. After impurity adsorption, the degree of OIT permeation in the CA membrane and the adsorption mechanism of CA were investigated by Fourier transform infrared spectroscopy and water‐adsorption studies. Further, we analyzed the porous characteristics and behavior of CA by scanning electron microscopy and conducted thermogravimetric analysis to observe the physical and chemical changes occurring in the polymers.
Effect of hydrodynamic heterogeneity on micromixing intensification in a Taylor–Couette flow reactor with variable configurations of inner cylinder

Published: February 2021

AbstractEffect of hydrodynamic heterogeneity on micromixing intensification in a Taylor–Couette flow (TC) reactor with variable configurations of inner cylinder has been investigated by adoption of a parallel competing iodide‐iodate reaction system. Two types of inner cylinder, circular inner cylinder and lobed inner cylinder (CTC and LTC), were used to generate hydrodynamic heterogeneity, focusing on the effects of the Reynolds number, the acid concentration, and the feeding time on the micromixing performance. Segregation index (Xs) was employed to evaluate the micromixing efficiency. It is revealed that Xs decreases with the increase of Reynolds number and feeding time but increases with the increase of acid concentration for both the CTC and LTC. However, the LTC does present a better micromixing performance at various operating conditions than that of the CTC as affirmed by both the experimental and computational fluid dynamics simulation results.
Cephalodiones A–D: Compound Characterization and Semisynthesis by [6+6] Cycloaddition

Published: February 2021

AbstractCephalodiones A–D (1–4), the first example of C19‐norditerpenoid dimers, were isolated and fully characterized from a Cephalotaxus plant. These new skeletal natural products shared a unique tricyclo[6.4.1.12,7]tetradeca‐3,5,9,11‐tetraene‐13,14‐dione core that was capped in both ends with rigid multicyclic ring systems either C2‐symmetrically or asymmetrically. Compounds 1–4 were proposed to be biosynthetically produced by the [6+6]‐cycloaddition of two identical C19‐norditerpenoid troponoids, which was validated by the semisyntheses of dimers 2–4. Moreover, some compounds showed significant inhibition on Th17 cell differentiation.
