Published: January 2021

Abstract. Waterlogging as a perennial problem is deep rooted on the urban fabrics of English Bazar Municipality. The present study pertains to vulnerability and risk assessment of flood and waterlogging susceptible areas in a micro or local scale, based on an integrated Analytic Hierarchy Process-Geographic information System (AHP-GIS) category model. For this purpose, a multi-criteria assessment of natural, quasi-natural and man-made factors have been performed. Criterion includes six parameters namely elevation, slope, soil, flow accumulation, land use land cover, density of digitized drain network which are responsible to initiate the waterlogged condition within municipality premises. The weights of all criterion are computed by pair wise comparison decision matrix (AHP). According to their weightage, information of different parameters are superimposed for a final weighted overlay analysis following a spatial modelling, under ArcGIS 10.5 platform to delineate the flood and water logging susceptible zones. The result obtained from this study indicate 11.45 %, 3.05 % and 85.49 % area of municipality corresponds with highly vulnerable, low and moderately vulnerable respectively. The major finding in the study reveals that unplanned urban expansion in the hazardous low-lying area by filling up of wetlands and depressions in association with inadequate drainage gravity provisions in the newly built-up wards (3, 23, 24 and 25) are noteworthy for resultant waterlogging condition. The present paper also aims to suggest long-term mitigation measures to be well integrated for arriving at a well drafted and implementable comprehensive drainage plan of English Bazar municipality.
Assessing the accuracy of remotely sensed fire datasets across the southwestern Mediterranean Basin
Authors: Galizia Luiz Felipe , Curt Thomas , Barbero Renaud , Rodrigues Marcos
Published: January 2021

Abstract. Recently, many remote-sensing datasets providing features of
individual fire events from gridded global burned area products have been
released. Although very promising, these datasets still lack a quantitative
estimate of their accuracy with respect to historical ground-based fire
datasets. Here, we compared three state-of-the-art remote-sensing datasets
(RSDs; Fire Atlas, FRY, and GlobFire) with a harmonized ground-based dataset
(GBD) compiled by fire agencies monitoring systems across the southwestern
Mediterranean Basin (2005–2015). We assessed the agreement between the RSDs and
the GBD with respect to both burned area (BA) and number of fires (NF). RSDs and the
GBD were aggregated at monthly and 0.25∘ resolutions, considering
different individual fire size thresholds ranging from 1 to 500 ha. Our
results show that all datasets were highly correlated in terms of monthly BA
and NF, but RSDs severely underestimated both (by 38 % and 96 %,
respectively) when considering all fires > 1 ha. The agreement
between RSDs and the GBD was strongly dependent on individual fire size and
strengthened when increasing the fire size threshold, with fires  > 100 ha denoting a higher correlation and much lower error (BA
10 %; NF 35 %). The agreement was also higher during the warm season
(May to October) in particular across the regions with greater fire activity
such as the northern Iberian Peninsula. The Fire Atlas displayed a slightly
better performance with a lower relative error, although uncertainty in the
gridded BA product largely outpaced uncertainties across the RSDs. Overall,
our findings suggest a reasonable agreement between RSDs and the GBD for fires
larger than 100 ha, but care is needed when examining smaller fires at
regional scales.
Simulating permeability reduction by clay mineral nanopores in a tight sandstone by combining computer X-ray microtomography and focussed ion beam scanning electron microscopy imaging
Authors: Jacob Arne , Peltz Markus , Hale Sina , Enzmann Frieder , Moravcova Olga , Warr Laurence N. , Grathoff Georg , Blum Philipp , Kersten Michael
Published: January 2021

Abstract. Computer X-ray microtomography (µXCT) represents a powerful tool for
investigating the physical properties of porous rocks. While calculated
porosities determined by this method typically match experimental
measurements, computed permeabilities are often overestimated by more than
1 order of magnitude. This effect increases towards smaller pore sizes, as
shown in this study, in which nanostructural features related to clay
minerals reduce the permeability of tight reservoir sandstone samples.
Focussed ion beam scanning
electron microscopy (FIB-SEM) tomography was applied to determine the permeability effects of
illites at the nanometre scale, and Navier–Stokes equations were applied to
calculate the permeability of these domains. With these data, microporous
domains (porous voxels) were defined using microtomography images of a tight
reservoir sample. The distribution of these domains could be extrapolated by
calibration against size distributions measured in FIB-SEM images. For this,
we assumed a mean permeability for the dominant clay mineral (illite) in the
rock and assigned it to the microporous domains within the structure. The
results prove the applicability of our novel approach by combining FIB-SEM
with X-ray tomographic rock core scans to achieve a good correspondence
between measured and simulated permeabilities. This methodology results in a
more accurate representation of reservoir rock permeability in comparison to
that estimated purely based on µXCT images.
Brief communication: The anomalous winter 2019 sea ice conditions in McMurdo Sound, Antarctica
Authors: Leonard Greg H. , Turner Kate E. , Richter Maren E. , Whittaker Maddy S. , Smith Inga J.
Published: January 2021

Abstract. McMurdo Sound sea ice can generally be partitioned into two regimes: (1) a stable fast-ice cover, forming south of approximately 77.6° S around March/April, then breaking out the following January/February; and, (2) a more dynamic region north of 77.6° S that the McMurdo Sound and Ross Sea polynyas regularly impact. In 2019, a stable fast-ice cover formed unusually late due to repeated breakout events. We analyse the 2019 sea-ice conditions and relate them to southerly wind events using a Katabatic Wind Index (KWI). We find there is a strong correlation between breakout events and several unusually large KWI events.
Surface composition of debris-covered glaciers across the Himalaya
using spectral unmixing and multi-sensor imagery
Authors: Racoviteanu Adina E. , Nicholson Lindsey , Glasser Neil F.
Published: January 2021

Abstract. The Hindu-Kush Himalaya mountain range is characterized by highly glacierized, complex, dynamic topography. The ablation area of these glaciers is often covered a highly heterogeneous debris cover mantle comprising ponds, steep and shallow slopes of various aspects, variable debris thickness and exposed ice cliffs. These surface elements are associated with differing ice ablation rates, and understanding the composition of the glacier surface is essential for a proper understanding of glacier hydrology and glacier-related hazards. Here we use high-resolution Pleiades (2 m) and RapidEye imagery (5 m) combined with Landsat Operational Land Imager (OLI) imagery (30 m) to estimate the composition of debris-covered glacier tongues across the Himalaya around the year 2015. We use linear spectral unmixing to map various types of debris, clean ice, supraglacial ponds and vegetation on debris-covered glaciers across the mountain range. We develop the spectral unmixing methods in the Khumbu region of eastern Nepal, and then apply them over the entire Himalaya (a glacier area of 2,254 km2). This allowed us to convert 30 m fractional maps into finer classification maps and to estimate the composition of debris-covered glaciers at various spatial scales. Debris-covered glaciers across the mountain range comprised 2.1 % supraglacial ponds, 12.8 % dark debris, 60.9 % light debris and 4.5 % supra glacial vegetation, with negligible amounts of clean ice and clouds and unclassified areas. Supraglacial ponds were more prevalent in the monsoon-influenced central-eastern Himalaya (up to 4 % of the debris cover area) compared to the monsoon-dry transition zone (only 0.3 %). The automated fractional supraglacial pond maps developed here serve to complement and improve the accuracy of existing regional lake datasets. They also provide a basis for exploring the turbidity of lakes and ponds as indicators of glacier change processes, and to monitor the evolution of ponds in the context of glacial hazards.
Updating the biological interest of 'Valeriana officinalis'
Authors: Sánchez Marta , González-Burgos Elena , Iglesias Irene , Gómez-Serranillos Cuadrado M. Pilar
Published: January 2021

Valeriana officinalis L. (Caprifoliaceae) has been traditionally used to treat mild nervous tension and sleep problems. The basis of these activities are mainly attributed to valerenic acid through the modulation of the GABA receptor. Moreover, V. officinalis is claimed to have other biological activities such as cardiovascular benefits, anticancer, antimicrobial and spasmolytic.  The current review aims to update the biological and pharmacological studies (in vitro, in vivo and clinical trials) of V. officinalis and its major secondary metabolites in order to guide future research. Databases PubMed, Science Direct and Scopus were used for literature search including original papers written in English and published between 2014 and 2020. There have been identified 33 articles which met inclusion criteria. Most of these works were performed with V. officinalis extracts and only a few papers (in vitro and in vivo studies) evaluated the activity of isolated compounds (valerenic acid and volvalerenal acid K). In vitro studies focused on studying antioxidant and neuroprotective activity. In vivo studies and clinical trials mainly investigated activities on the nervous system (anticonvulsant activity, antidepressant, cognitive problems, anxiety and sleep disorders). Just few studies were focused on other different activities, highlight effects on symptoms of premenstrual and postmenopausal syndromes. Valeriana officinalis continues to be one of the medicinal plants most used by today's society for its therapeutic properties and whose biological and pharmacological activities continue to arouse great scientific interest as evidenced in recent publications. This review shows scientific evidence on traditional uses of V. officinalis on nervous system.

Analysis of Measurement and Evaluation Methods in Undergraduate Education According to the Core Education Program: Physiotherapy and Rehabilitation Example
Authors: Kul Karaali Hayriye , Ilgın Duygu , Özcan Özlem , Seçer Erhan
Published: January 2021

INTRODUCTION: Our research was carried out to investigate the use of measurement and evaluation methods proposed in the National Core Education Program of Physiotherapy and Rehabilitation in Physiotherapy and Rehabilitation undergraduate programs. METHODS: Official websites of the Physiotherapy and Rehabilitation programs, which are in the top 10 within the health sciences faculties of public universities, were examined. RESULTS: Data of a total of 374 courses were reached in ten universities. The measurement and evaluation methods used in these courses were recorded as exam (n = 374; 100%), homework (n = 165; 44.11%), practice (n = 106; 28.34%), presentation (n = 103; 27,54%), individual work (n = 76; 20.32%), class participation (n = 68; 18.18%), project (n = 55; 14.70%), attendance (n = 50; 13,36%), internet browsing (n = 36, 9.62%), library study (n = 36; 9.62%), laboratory (n = 33; 8.82%), field study (n = 26;% 6.95), mini exam (n = 26; 6.95%), reading activities (n = 20; 5.34%), preparing a presentation (n = 13; 3.47%), seminar (n = 8; 2.13%), material design (n = 3; 0.80%) and report preparation (n = 2; 0.53%). DISCUSSION AND CONCLUSION: Our study showed that the skills-based and performance-based measurement and evaluation methods proposed in the National Core Education Program, which are designed to effectively evaluate the competencies planned to be acquired for students, are used less than other methods in undergraduate programs. For this reason, it is considered that the undergraduate program education plans need to be updated according to the National Core Education Program of Physiotherapy and Rehabilitation.

This paper uses the prefecture-level data from 2003 to 2016 of the Yangtze River Delta region of China and uses the spatial Dubin model(SDM) to study the promotion effect of transportation infrastructure on industrial agglomeration and the spatial spillover effect: First, it is found that there is a significant positive spatial correlation between transportation infrastructure development at the prefecture and city level governments in China, which supports the hypothesis of intergovernmental transport infrastructure competition in this paper; secondly, the regression of the spatial measurement model proves that transportation infrastructure has a certain role in promoting regional industrial agglomeration, and enhances the level of industrial agglomeration in the surrounding areas through spatial spillover effects; in addition, this article uses the Spatial Dubin Model(SDM)) partial differential decomposition method to explore the spatial spillover effects of transportation infrastructure on the flow of elements (this paper explores the spatial spillover effects of transport infrastructure on factor mobility using a partial differential decomposition of the Spatial Durbin Model(SDM)); finally, the robustness of the results of this paper is tested using the replacement space weight matrix and estimation method.
Strategies for strong motion earthquake recording in New Zealand
Authors: Stephenson W. R.
Published: January 2021

The problem of how to record future strong earthquakes in New Zealand is examined by considering what data is required, how effective the present network will be in gathering that data, and what new technology is now available. It is concluded that present methods result in an unsatisfactory use of funds. There is a current emphasis on frequent expert servicing which, while it leads to a high probability of any recorder operating, restricts the number of installations able to be serviced. Thus we have a high probability of any given recorder working, coupled with a small probability of any given earthquake being within range of a recorder. The suggested future strategy is to first develop a new accelerograph of high reliability and the capability of self testing. This would incorporate a non volatile no moving parts electronic memory. Servicing of this would be at infrequent intervals, but a program of reporting the self test results by postcard would be adopted. By thus cutting down on recorder servicing and record processing times, we could force the major factor to be capital cost, and thus allow the network to expand until a realistic probability of recording a major earthquake was reached. The installation of about 70 additional strong motion accelerographs in the main seismic region would allow a good chance of recording our next major earthquake.
An O(nlogn/logw) Time Algorithm for Ridesharing
Authors: Han Yijie , Sun Chen
Published: January 2021

In the ridesharing problem different people share private vehicles because they have similar itineraries. The objective of solving the ridesharing problem is to minimize the number of drivers needed to carry all load to the destination. The general case of ridesharing problem is NP-complete. For the special case where the network is a chain and the destination is the leftmost vertex of the chain, we present an O(nlogn/logw) time algorithm for the ridesharing problem, where w is the word length used in the algorithm and is at least logn. Previous achieved algorithm for this case requires O(nlogn) time.
The Associations between Oral Health Literacy and Oral Health-Related Behaviours among Community-Dwelling Older People in Thailand
Authors: Piyakhunakorn Panat , Sermsuti-anuwat Nithimar
Published: January 2021

OBJECTIVE: This study aimed to investigate the associations between oral health literacy and oral health behaviours among community-dwelling older adults in Thailand.

MATERIAL & METHODS: This community-based cross-sectional study was conducted at the District Health Promoting Hospitals (DHPH), Panarae district, Pattani province, Thailand, between 1-30 June 2020. A total of 271 community-dwelling older adults participated in the study. The inclusion criteria were independent living elderly who were 60 years or over and had at least one remaining tooth. Those who had a communication problem, severe chronic diseases, or disabilities were excluded. Data were collected by questionnaire interviewing. Binary logistic regression was analyzed.

RESULTS: In the final model of regression analyses, older age (OR = 1.810, p = 0.035), limited education levels (OR = 2.113, p = 0.027), and participants who had the frequency of tooth brushing less than two times per day (OR = 1.905, p = 0.047) were statistically significant predictors of lower oral health literacy levels.

CONCLUSIONS: The findings confirmed the strong associations between OHL and age, education levels, including the frequency of toothbrushing in the participants. This evidence indicates that an appropriate education program about oral health promotion probably induce adequate oral health literacy among the older population.

Valor Social Integrado (VSI) del Hospital de Santa Marina en Bilbao: monetizando el valor social para los ‘stakeholders’
Authors: Molinero Frumen , San-José Leire , Molinero Álvaro
Published: January 2021

En la actualidad, las organizaciones tienden a legitimarse por el valor social que generan, y no solo por el económico. Para el caso de la sanidad, esta perspectiva es obvia, ya que las entidades sanitarias se deben a sus pacientes y a su bienestar. Para ello, será necesario saber qué opinan los stakeholders perceptores del valor social. Este artículo va más allá, y no solo se conocen los valores sociales, sino que se llegan a monetizar. Así se logra saber cuál es el valor social generado por un hospital, el Hospital de Santa Marina de Bilbao. Además, se analiza cuáles son los aspectos más complicados en su aplicación, qué les aportó y cómo es posible extenderlo a otros hospitales.

Knowledge and opinions of patients attending a hospital emergency
Authors: Kuręda Grzegorz , Lisowska Ada
Published: January 2021

Background: The high occupancy rate of hospital emergency departments (ED) necessitates the selection of
patients whom an excessively long waiting time for medical assistance may result in deterioration of their health
condition or pose a threat to life. Medical categorization plays an important role in the identification of such
patients.
Aim of the study: The aim of this study was to determine the level of knowledge, and opinions, of patients
attending the ED regarding the purpose and processes surrounding the use of triage.
Material and methods: This study included 123 patients attending the ED of the University Clinical Hospital
(UCH) in Opole in the period from January to March 2019. Study participants carried out a questionnaire
after leaving the triage room.
Results: Most participants (93.50%, n = 115) gave a correct answer to the question of what triage is, and 90.20%
(n = 111) gave a correct answer to the question of its purpose. Most patients felt that triage was needed (73.20%,
n = 90), and 54.50% (n = 67) felt that ED staff should refer patients without life-threatening conditions to the
PHCF (Primary Health Care Facility) or OOHC (Out of Hours Care) unit. Most participants (59.30%, n = 73) were
aware of which color to which they had been assigned following medical categorization.
Conclusions: The level of knowledge of patients attending the ED regarding the triage process was generally
good, but nevertheless ED staff should ensure attendees are provided with information on the urgency category
assigned to them and estimated waiting time, as well as information regarding possible delays. Information
leaflets or short videos on ED operation and admission procedures may play an important role in the education
of patients in waiting rooms.

U članku se iznose rezultati kvalitativnog istraživanja rodne podjele kućanskih poslova u Hrvatskoj, u širem okviru ukupnih radnih praksi kućanstava (tj. ukupnoga plaćenog i neplaćenog rada koji pridonosi ostvarivanju njihovih ciljeva). Podatci su prikupljeni kroz 92 polustrukturirana intervjua (34 s muškarcima, 43 sa ženama i 15 partnerskih), provedena u svim hrvatskim regijama, uz visok stupanj varijacije po sociodemografskim obilježjima. Primijenjena je relacijska rodna analiza, čiji je teorijski okvir počivao ponajprije na Bourdieuovu prakseološkom pristupu konceptu strategije, kao i na Pahlovoj konceptualizaciji ukupnog rada kućanstva, te analizi rodne dimenzije strategija kod Hochschild. Procesi kategorizacije uključivali su tri razine kodiranja (referentno, otvoreno i selektivno), a procesi povezivanja izradu analitičkih profila i tablica. Identificirane individualne rodne strategije povezane s obavljanjem kućanskih poslova jesu: strategije neupitnosti, otpora promjeni, suradnje, te proaktivne egalitarnosti (kod muškaraca) i strategije neupitnosti, pritiska, pristajanja, te proaktivne egalitarnosti (kod žena). Dovođenjem u odnos navedenih muških i ženskih individualnih strategija, uz primjenu kriterija rodne ravnoteže, dobivena je sljedeća tipologija strategija kućanstava u Hrvatskoj s obzirom na podjelu kućanskih poslova: neupitno tradicionalna, pretežno tradicionalna, početno egalitarna i proaktivno egalitarna. U dijelu muških i ženskih individualnih strategija pojavljuje se i komponenta opravdavanja u podjeli kućanskih poslova. Teorijski je doprinos analize primjena Bourdieuova prakseološkog pristupa strategijama u relacijskom istraživanju roda.

Os sentidos mudam e a cozinha também: análise da(s) formação(ões) discursiva(s) das propagandas da Todeschini
Authors: Lima Heitor Pereira de , Silva Kátia Regina de Sousa e
Published: January 2021

Este trabalho parte da compreensão de que a noção de formação discursiva corresponde a um domínio de saber, constituído de enunciados discursivos que representam um modo de relacionar-se com a ideologia vigente, regulando o que pode e deve ser dito (PÊCHEUX, 1988). Nesse sentido, evoca-se a noção de sujeito, categoria analítica que difere pontualmente o quadro teórico da Análise do Discurso de linha francesa pêcheuxtiana das demais teorias que também contemplam o discurso. Embora este ensaio assume seu interesse por formação discursiva, não pretendemos perder de vista a noção de tomada de posição, formações ideológicas e sujeito, como já anunciamos, uma vez que a reunião dessas noções é fundamental para que consigamos acesso aos efeitos de sentido mobilizados pelas formações discursivas (estas a serviço de ideologia) que autorizam o discurso. Para isso, utilizaremos como corpus três textos propagandísticos da empresa de cozinhas planejadas Todeschini e buscaremos aporte teórico em Michel Pêchuex (1988), por sua importância na teorização do conceito de formação discursiva pela qual foi possível, ao considerar as formações ideológicas, esgarçar o olhar sobre essa categoria analítica tão cara aos estudos discursivos; Michel Foucault (1969), pela sua preocupação em estabelecer as regularidades, os sistemas de dispersão; e Freda Indursky (2020) por compreender sua relevância às pesquisas que visam explorar formações discursivas, sobretudo àquelas que elegem corpus da realidade brasileira.
Strengthening International Health Security by Embedding the Role of Civil Society Organizations in National Health Systems: Lessons from the 2014–2016 West Africa Ebola Response
Authors: Hushie Martin , Suhuyini Salifu Rita , Seidu Iddrisu
Published: January 2021

Following the recent global health crises, such as the 2014 Ebola and 2016 ZIKA outbreaks, the international health community’s ability to deal with such threats has been debated. Amid discussions of how international health security (IHS) and related national health systems should and could be strengthened, the potential of harnessing the role of civil society organizations (CSOs) for more effective responses has been frequently raised. Such participation is often based on the notion that CSOs by their grassroots presence can more effectively help to address health security and health systems challenges in affected populations and communities. Using the World Health Organization’s (WHO) health systems’ building blocks as an evaluative framework, this chapter examines CSOs’ roles and responsibilities during the 2014–2016 West Africa Ebola Outbreak and how they can be further empowered to perform these functions. The chapter draws conclusions about the opportunities and challenges CSOs represent for strengthening IHS and national health systems during public health emergencies in low- and middle-income countries (LMICs).
An Analysis of Emotional and Psychological Issues among Males at the Correctional Institution in St. Vincent and the Grenadines
Authors: Stamatakis Nikolaos , C. Burnett Allan
Published: January 2021

Recent findings suggest that emotional instability and psychological disorder rate in prison is three times higher than in the general population. Prisoners – especially males – are also at increased risk of all-cause victimization including violence and self-harm. This research sought to identify and analyze the emotions that incarcerated males at the Correctional Institutions in St. Vincent and the Grenadines have had and or were encountering, as well as the manner these emotions were being dealt with. It also sets out to ascertain some of the factors that were playing prominent roles in the lives of incarcerated males regarding those emotions. Up to date, there has been no research work done on males and their emotions in St. Vincent and the Grenadines nor any study regarding inmates in the correctional institution. The administration of a short questionnaire formed the quantitative collection instrument, which provided data from 150 inmates. The data analysis was performed via SPSS, and the findings point to a cross-section of relational factors that are relevant to males and their emotions (namely, abuse, crying, bonds, and suicidal thoughts). It was found that males are struggling emotionally with understanding their identity and are inadvertently pressured to adhere to societal directives by restricting their emotional expression.
Vulnerable to Contingency
Authors: Keenan James F. ,   Philosophy Documentation Center
Published: January 2021

Over the past forty years, the administrations of American colleges and universities have developed and expanded the ranks of contingent faculty as an alternative to the tenure line. While acknowledging the gross inequities that divide these two tracks, this essay attempts to awaken tenure-line ethicists through the concept of recognition to the conditions of their colleagues and then argues through the concept of vulnerability that faculty are deeply and unavoidably related, and concludes that through solidarity ethicists from both lines might work together toward the university becoming a more ethical workplace than it presently is.
The effect of Covid-19 on labour migration in the CIS
Authors: Ryazantsev S. V. , Molodikova I. N. , Bragin A. D.
Published: January 2021

This study responds to the need for measures to mitigate the effects of national actions to slow the spread of Covid-19. National responses are dynamic processes and thus an elusive, albeit important, object of study. The governments of most CIS countries acted promptly and decisively in countering the pandemic. The comprehensive measures have had a serious impact on citizens’ mobility and employment situation. Among the affected are millions of migrants working in the CIS. This article offers a comparative analysis, followed by synthesis, of the negative effects of the Covid-19 pandemic as seen through the prism of employment and the situation of migrant workers in the CIS. Another focus is the restriction and support measures and how they have affected migrants. A range of qualitative and quantitative data was collated on the situation of migrant workers during Covid-19 restriction in the Russian Federation and across the CIS. The findings suggest that the lack of international coordination in tackling Covid-19 has complicated the situation of migrant workers, who suffer from the closure of borders and the absence of adequate social support. The article explores problems faced by migrant workers in the current crisis and proposes measures to alleviate them.

Particular attention is paid to the media strategies pursued in the study area. The research is based on Russian and English texts from the Baltic media, WHO official documents and datasets, as well as initiatives of the Baltic Sea region organisations (2020) counteracting Covid-19. A combination of these sources builds up an objective view of the situation and demonstrates how the pandemic and its consequences are represented in public consciousness given a certain pragmatic goal. The pandemic is a new type of threat; its consequences demonstrate a tendency towards negative synergy and a category shift from soft threats to hard ones. The research shows that several key strategies — counter-active, projective, conservative, mobilising, resilient, and reflective — are used to communicate the threat and its consequences in the media.
The Surfer Problem: A Whys Approach
Authors: Copes Larry , Kahan Jeremy
Published: January 2021

In this article we compile the experiences that classes of secondary teachers we have taught have had with a particular problem. That the problem is suitable for use with high school students is evidenced by its inclusion in an Education Development Center publication(2000) and by the testimony of teachers who have used it, such as Cuoco, Goldenberg, and Mark (1995).
Dandelin Spheres

Some mathematical constructions are simple and straightforward, some are just tedious, and a special few can best be described as elegant. These unusual formulations can sometimes grab a student's attention when most other topics leave him cold. Dandelin spheres is one of those amazing topics.
Connecting Research to Teaching: Making the Right (Discourse) Moves: Facilitating Discussions in the Mathematics Classroom
Authors: Springer G. T. , Dick Thomas
Published: January 2021

The mathematics classroom envisioned by the NCTM Principles and Standards (2000) is one in which teachers deliver fewer monologues and engage in more dialogues with students. The teacher is not an ordinary participant in mathematics classroom discussion but plays a special role in facilitating and steering discourse. Calls for encouraging discourse in mathematics classrooms are pervasive, and the analysis of discourse has become a prominent theme in current mathematics education research. Nevertheless, while many teachers may feel the goal is a worthy one, some may also feel at a loss as to the specific strategies or techniques that may be used to encourage and facilitate meaningful mathematical discourse among their students.
Making Math Happen: An Interactive, Technology-Rich Approach
Authors: Rolfe Eleanor W.
Published: January 2021

Many mathematics teachers hold the tantalizing conviction that if their students could only just see mathematics happen, make mathematics happen, they would get it. When students do mathematics interactively, they are able to fiddle with parameters, watch the effect of making those changes, and begin to construct their own mental models. Computers, with well-designed software, can both remove the tedium and redundancy of calculation and provide dynamic visuals, lending themselves to the task of giving students such opportunities. The Shodor Education Foundation's Interactivate provides such software, freely available, on its Web site.

M&M's, Rhinos, Cockroaches, and Cooperative Learning in Mathematics Classrooms
Authors: Rubel Laurie H.
Published: January 2021

NCTM's Communication Principle states that instructional programs at all grade levels should enable students to “organize and consolidate their mathematical thinking through communication; communicate their mathematical thinking coherently and clearly to peers, teachers, and others; [and] analyze and evaluate the mathematical thinking and strategies of others” (NCTM 2000, p. 60). He then shares two limitations of SmartView and follows with instructions on using scripts, emulator states, and the keystroke history features and on taking screen shots.

President's Choice: President's Report: Better Teaching, Better Mathematics: Are They Enough?
Authors: Crosswhite F. Joe
Published: January 2021

The favorite article of a past NCTM president chosen for reprise as part of the celebration of the journal's 100th volume year. This article reports on the health of school mathematics education in the mid-1980's, right after the US Department of Education published What Works. SIMS reported our very best student did not compare well with their counterparts in other countries. Have we made any strides forward in the past 20 years to meeting the challenge laid out in the article?
Intersections of a Circle and a Square: An Investigation
Authors: Canada Dan , Blair Stephen
Published: January 2021

The investigation of how a circle and square lying in the same plane could intersect each other is an excellent example of geometric problem-solving. This paper explores three facets of the investigation: (1) finding out how many points of intersection are possible, (2) classifying the different ways of intersection, and (3) determining which ways are constructible, and how. Altogether, the investigation offers students and teachers alike a venue for exploring a rich task in geometry. Includes student work.
Sound Off!: To CAS or Not to CAS?
Authors: Freda Andrew
Published: January 2021

The AP Calculus Listserv recently posted an interesting discussion about whether mathematics teachers should continue to teach certain algebraic techniques such as rationalizing a numerator or whether we should move students away from symbolic manipulation and toward the use of computer algebra systems (CAS). One writer, who was concerned about mathematical literacy and cognitive development, argued against using CAS, contending that the activity of symbol manipulation helps solidify or enhance conceptual understanding of mathematics. Another writer, who was in favor of CAS, maintained that once teachers are convinced that students understand the idea behind a given skill, we should allow them to use CAS rather than practice the traditional skills of algebra.
A, E, I, O, U and Always Y: A Simple Technique for Improving Communication and Assessment in the Mathematics Classroom
Authors: Vazquez Lorna Thomas
Published: January 2021

Have you heard the one about the boy who taught his dog, Spot, to whistle? With his buddies gathered around, he administered the test. “Whistle, Spot,” he commanded, but the dog did not respond. “Whistle!” he repeated. But Spot remained mute. “I thought you said you taught him how to whistle,” one playmate chided. “I did teach him how,” replied the boy, “but I didn't say he learned it.”
Designer Functions: Power Tools for Teaching Mathematics
Authors: Weinhold Marcia Weller
Published: January 2021

What would you do if you had only one semester to help prospective teachers understand all you had learned from teaching high school mathematics for seventeen years and from researching how students learn mathematics? I want prospective teachers to see the difference between knowing how to do mathematics and knowing how to teach mathematics. I want to show that what is important is what students do; what the teacher does must be in the background. On the other hand, these preservice teachers' major concern is that they have not studied high school mathematics since they themselves were in high school. In addition, they usually are able to use technology to do mathematics but have little experience using technology to teach mathematics.
Activities for Students: What Did One Angle Say to the Other Angles?
Authors: Fairbairn Donald M.
Published: January 2021

Robert Oppenheimer (1904–67), the famous theoretical physicist known as the father of the atomic bomb, was once asked how he became such a great scientist. He replied that early on he had teachers who afforded him, as he put it, the joy of discovery. It truly is a joy to discover something for yourself, even if it were previously discovered by someone else. Discovery learning should be a significant part of the mathematics curriculum. Activities that lead students to discover some interesting and perhaps unexpected results are fun for both students and teachers. This article presents an inductive angle-sequence activity that uses paper folding to arrive at a surprising conjecture. Two versions of a second activity leading to deductive verification of the conjecture are also provided. Although these activities are suitable for individual effort, I find that having students work in small groups of three or four students is more enjoyable for them and thus have formatted the activities for group effort.
Selecting and Using Mathemagic Tricks in the Classroom
Authors: Matthews Michael E.
Published: January 2021

As a mathemagician, I know that learning magic tricks has immense appeal for many mathematics teachers. I also suspect that teachers may not use these mathemagic tricks effectively in their classrooms and that some see them only as “five-minute fillers.” However, mathemagic can be used meaningfully in the classroom. To help teachers do so, I provide some mathemagic examples that fit nicely into typical secondary curricula and encourage teachers to think through how each trick may aid students' conceptual and procedural understanding

Probability in Practice: The Case of Turkey Bingo
Authors: Danielson Christopher , Jenson Eric
Published: January 2021

The Wednesday before Thanksgiving presents a challenge to teachers in many U. S schools. Some students are absent because they are traveling to be with their extended families for the holiday. Other students, assuming that nothing important will happen at school when so many of their peers are absent, may also be absent. One school's solution to the attendance problem on this day is to have a daylong bingo game. This article recounts a mathematics problem that arose in this schoolwide game in one recent year, explores the mathematics behind solving the problem, and briefly examines two technological approaches to the solution.
