Potencialidad de Puerto Deseado y Camarones (Argentina) como destinos de cruceros a partir de sus competencias territoriales
Authors: Cohen Carolina , Vereda Marisol , Benseny Graciela
Published: January 2021

El turismo de cruceros está comúnmente asociado a una práctica exógenamente determinada. Sin embargo, como práctica social, se emplaza en un espacio cargado de connotaciones sociales y culturales; haciendo uso de un territorio construido socialmente. Desde esta mirada la decisión de optar por este tipo de actividad es tomada teniendo en cuenta un conjunto de elementos que va más allá de las características del buque. Los territorios en cuestión deben poseer una serie de condiciones que resulten favorables para su competitividad, fundamentalmente asociadas a la presencia de recursos naturales y culturales que conforman la oferta de sitios potenciales de visita y la prestación de servicios. Estos factores forman parte de las competencias territoriales que poseen los destinos y pueden actuar como elementos que favorezcan y potencien su inserción en el turismo de cruceros. Puerto Deseado y Camarones, dos puertos de la Patagonia argentina, han mostrado interés por esta actividad surgiendo el interrogante respecto a las competencias territoriales que poseen para el desarrollo del turismo de cruceros. El trabajo optó por un enfoque cualitativo, apoyado en técnicas cuantitativas desarrollado durante la temporada de verano 2017-2018 y consistió en el relevamiento y análisis de diferentes componentes territoriales complementado con la opinión de informantes clave. Los resultados obtenidos reflejan la potencialidad que poseen ambas localidades en términos de sitios de visita y planta turística destacándose que, si bien cuentan con un conjunto de componentes territoriales que los posicionarían competitivamente en el mercado de cruceros, también es necesario fortalecer otros.
Juntarse para alejarse y reproducir la clase. Estrategias residenciales de las clases medias en los márgenes asignados por el mercado. El caso de la población beneficiaria del plan PROCREAR en la ciudad de La Plata (2013-2015), Argentina.
Authors: Ventura Violeta
Published: January 2021

En los estudios urbanos latinoamericanos hay una vacancia respecto al rol de las clases medias en la producción de ciudad. También sobre el modo en que sus anclajes territoriales contribuyen a la construcción de la propia clase. En este artículo buscamos aportar a esa vacancia mediante el análisis de una estrategia residencial colectiva que, frente a los límites estructurales que les impuso el mercado de suelo, protagonizaron un grupo de beneficiarios/ as de un programa hipotecario para la vivienda destinado a las clases medias de Argentina. El caso de estudio en el que nos basamos es el de la ciudad de La Plata (2013-2015). Nuestros objetivos específicos son, (1) analizar las operaciones de distanciamiento y cercanía social que motorizaron dicha estrategia, deteniéndonos en cómo se pusieron en juego las externalidades de vecindad, y las percepciones en torno a la intervención estatal. (2) Reconstruir las búsquedas de terrenos y evaluaciones de distintas zonas de la ciudad realizadas por un subgrupo de beneficiarios/as, para analizarlas en relación con la dinámica urbana local. Para ello, adoptamos una perspectiva teórica pragmático-pragmatista, y consecuentemente un enfoque metodológico cualitativo sustentado en tres fuentes de datos: la observación de campo, las entrevistas en profundidad y la etnografía virtual. Nuestra principal conclusión es que dicha estrategia fue un proceso activo y recursivo de diferenciación social y espacial. Una operación de acercamiento social en la cual (ante su inminente suburbanización) integrantes de las clases medias platenses, buscando resguardar (y producir) su posición en el espacio social, reprodujeron una forma segmentada de residir en la ciudad.

Authors: Páez Cuba Lisett Daymaris , Carballo Moya Adoración
Published: January 2021

La relación intrínseca entre la epistemología jurídica y la Didáctica del Derecho constituye el punto de partida para abordar el proceso de enseñanza-aprendizaje del Derecho en las Universidades. A su vez, el contexto internacional y el desarrollo de las relaciones multifacéticas actuales, aclaman de nuevos enfoques inter, multi y transdisciplinarios respecto al iusinternacionalismo. El objetivo del presente trabajo está dirigido a fundamentar una estrategia pedagógica para la enseñanza de las relaciones internacionales en la carrera de Derecho en Cuba, de manera que tribute a la formación integral del jurista. Se analiza la interconexión entre dos ciencias: el Derecho y las Relaciones Internacionales, con particular incidencia en el abordaje del Derecho Internacional. Se realiza una revisión de planes de estudios foráneos y nacionales, los cuales sugieren la previsión curricular de competencias profesionales genéricas y específicas. La propuesta aborda una estrategia pedagógica concebida para lograr el rediseño curricular del Derecho Internacional como disciplina científica, la transversalidad de la enseñanza de las relaciones internacionales en la carrera de Derecho y la inclusión de un sistema de actividades extracurriculares que potencien los juegos de roles profesionales en el estudiante de Leyes.
The Trade Effects of Regional Agreements and Economic Integration Processes in Europe, South America, and North America
Authors: Lopez Oscar David , Carvajal Alexander
Published: January 2021

This article seeks to understand the effects of trade creation and diversion in regional agreements and integration processes in Europe, South America, and North America. Through a systemic literature review, and based on the economic theory of integration, it analyzes the impact of tariff barriers on trading volume through the world, as well as the impact of barriers removals in member and non-member countries that participate in these trade agreements. As hypothesis, it can be stated that the trade effects generated by economic integration processes vary depending on the endogenous conditions of the industries in member countries, in addition to the consolidation phase of the integration processes. For this purpose, a qualitative descriptive methodology, based on an analysis of literature, is used to determine the trade creation and deviation effects of agreements in Europe (European Union), South America (MERCOSUR and CAN), and North America (NAFTA).

Authors: Skinner R. I. , Tyler R. G. , Heine A. J. , Robinson W. H.
Published: January 2021

The development of hysteretic dampers for the protection of structures against earthquake attack, carried out at the Physics and Engineering Laboratory over the past six years, is described. Details of both steel and lead devices and their application to bridges and base isolated buildings are given. Steel devices are designed to absorb energy by plastic deformation in torsion or bending, while lead devices rely on plastic extrusion or shear. The characteristics of PTFE sliding bearings are also described and the possibility of using this type of bearing to permit sliding on base isolated systems, and to allow dissipation of energy in joints in conventional structures, referred to. The most promising development is in the lead rubber bearing in which the properties of load-bearing and damping are combined in one unit.
Indoor Localization Based on Fingerprint Clustering
Authors: Chen Shi
Published: January 2021

With the rapid development of the huge promotion of the Internet and artificial intelligence, the demand for location-based services in indoor environments has grown rapidly. At present, for the localization of the indoor environment, researchers from all walks of life have proposed many indoor localization solutions based on different technologies. Fingerprint localization technology, as a commonly used indoor localization technology, has led to continuous research and improvement due to its low accuracy and complex calculations. An indoor localization system based on fingerprint clustering is proposed by this paper. The system includes offline phase and online phase. We collect the RSS signal in the offline phase. We preprocess it with the Gaussian model to build a fingerprint database, and then we use the K-Means++ algorithm to cluster the fingerprints and group the fingerprints with similar signal strengths into a clustering subset. In the online phase, we classify the measured received signal strength (RSS), and then use the weighted K-Nearest neighbor (WKNN) algorithm to calculate the localization error. The experimental results show that we can reduce the localization error and effectively reduce the computational cost of the localization algorithm in the online phase, and effectively improve the efficiency of real-time localization in the online phase.
POR UMA ÉTICA DA LINGUAGEM: SOBRE O SUPOSTO CARÁTER SOLIPSISTA E MONOLÓGICO DA RAZÃO PRÁTICA
Authors: Simões Felipe Rodrigues
Published: January 2021

O presente artigo pretende introduzir um conjunto de reflexões que versam sobre o problema da mentira e do dever de veracidade enquanto elementos que estruturam a filosofia prática de Kant. Para tanto, ocupa-se do primado da linguagem como questão fundamental da filosofia crítica. Em seguida, tematiza alguns dos principais momentos onde o referido problema se apresenta. Assim, além de uma reconstrução das teses gerais que constituem a parte transcendental da doutrina moral-prática, busca indicar em que medida os juízos sintéticos a priori práticos encontram na natureza humana, interpretada sensivelmente, seu domínio factual de aplicação. Tal esforço constituirá uma resposta indireta às críticas dirigidas por Karl-Otto Apel e Jürgen Habermas contra um suposto caráter solipsista e monológico da razão prática, de modo a sustentar que, em fim de contas, não seria Kant apenas o mais natural aliado desses dois pensadores, mas, sobretudo, que sua concepção de razão prática seria essencialmente dialógica.
A CONSCIÊNCIA SEGUNDO JULIAN JAYNES
Authors: Rodrigues Filho Márcio Francisco
Published: January 2021

O artigo contrasta a hipótese da consciência defendida por Julian Jaynes com os conhecimentos fisiológicos do cérebro humano para sugerir contradições. Na controversa hipótese do surgimento da consciência por meio de uma mente bicameral, Jaynes explicou a origem da consciência por meio de dois aspectos centrais da sua afamada obra "The Origin of Consciousness in the Breakdown of the Bicameral Mind". Aqui, primeiro abordamos os pressupostos que levaram Jaynes a defender a hipótese da mente ser inconsciente na antiguidade (3500 a.C a 1400 a.c) e dividida em dois hemisférios autônomos, as quais, um alucinava comandos e o outro os executava, sem que tivessem introspecção, metacognição ou ainda, consciência em um sentido mais amplo. Depois, contrastamos a teoria com os aspectos fisiológicos e analisamos alguns problemas acarretados pela hipótese, concluindo com um resumo dos principais aspectos desse trabalho com comentários lançados por respeitados pesquisadores.
ALGUNS APONTAMENTOS SOBRE A HERMENÊUTICA FILOSÓFICA DE HANS-GEORG GADAMER
Authors: Neto Francisco Alvarenga Junnior
Published: January 2021

O presente artigo versa sobre a forma com que o filósofo alemão hermeneuta Hans-Georg Gadamer, em seu construto teórico, concebeu e discutiu o tema da verdade. Para tal, buscar-se-á realizar um breve itinerário entre as elucubrações gadamerianas em torno do tema que não se apresenta de forma clara e objetiva, o que, aparentemente, é fruto da própria psicologia do filósofo, que sempre se mostrou disposto ao diálogo, não determinando de forma acabada os conceitos e temas sobre os quais se debruçou. Assim, buscar-se-á explicitar a crítica de Gadamer à modernidade, o que se seguirá de uma rápida apresentação da compreensão tradicional filosófica acerca da hermenêutica, apresentando aí alguns autores vinculados ao seu desenvolvimento, os quais influenciaram a Gadamer ou sofreram sua influência, como é o caso de Schleiermacher, Dilthey e Heidegger. Em seguida, após tal apresentação, trataremos da forma como a hermenêutica foi compreendida por Gadamer e, também, a forma com que ele compreendeu a verdade, inserida na história, como uma constante manifestação.

Trata-se, o presente texto, de uma aula ministrada no curso para diversas graduações, como direito, psicologia, geografia, etc. de Introdução à Filosofia: Ética, na Universidade Federal de Minas Gerais (UFMG), como cumprimento do estágio docente do doutorado em Filosofia, sob a supervisão do Prof. Dr. Tadeu Mazzola Verza. Sendo assim, nosso objetivo era duplo: apresentar uma introdução filosófica acerca de questões éticas e, ao mesmo tempo, introduzir nossos estudantes ao estilo filosófico ricoeuriano. Para alcançarmos isso, escolhemos a temática da Declaração Universal dos Direitos Humanos e como esta era vista pelo senso comum dos brasileiros. A partir dos dados obtidos, por meio de uma investigação estatística, exploramos, usando alguns recursos didáticos, como tirinhas, as fronteiras e relações que existe para Paul Ricoeur entre as fontes não filosóficas e a elaboração própria de um ponto de partida para filosofia. Por fim, convidamos os estudantes, ao citar um
LA PESTE Y EL ARTE, ALGUNAS REFLEXIONES
Authors: Mendoza Celina A. Lértora
Published: January 2021

La peste es una realidad recurrente en la historia humana desde los más remotos tiempos. Cualquier persona medianamente culta o memoriosa puede mencionar diversas lecturas sobre ella; quien haya vivido más de cinco décadas puede recordar episodios que le tocó presenciar. Así, podemos evocar desde la primera gran peste de que se tengan noticias y narraciones, como la de Atenas en el siglo V ac, hasta la que estamos padeciendo en todo el planeta. La peste ha sido omnipresente en un sentido recurrente en el tiempo y expansivo en el espacio; hoy es omnipresente en sentido absoluto. Además, es un fenómeno impactante, trágico en sí mismo y en sus consecuencias. Provoca grandes sufrimientos físicos en las víctimas, daños psíquicos en todos los directa o indirectamente afectados (miedo, ansiedad, depresión) y consecuencias de enorme significación en la sociedad y en todos los aspectos de la vida, que incluyen a varias generaciones. En este breve trabajo me propongo reflexionar sobre este punto, sin pretender ni mucho menos una historia del tema. Tomaré solamente tres casos que, en cierto modo pueden considerarse ejemplos claros de esta asimetría en que los rasgos negativos prevalecen ampliamente sobre los positivos pero, paradojalmente, sirven de gran marco para destacar los heroísmos y los martirios minoritarios.

Background: Marine seaweeds synthesize different metabolites with various biological activities, including antimicrobial effects. Objectives: The main object of this study was to fractionate the seaweed Padina australis and analyze the antimicrobial activities of these fractions to isolate the bioactive compounds. Methods: Padina australis was collected from the Persian Gulf and extracted by maceration with methanol-ethyl acetate solvent. The extract was evaporated and partitioned by the Kupchan method to yield hexane, dichloromethane, water, and butanol partitions. Dichloromethane partition was further fractionated by MPLC, and antimicrobial activity of the crude extracts and all fractions were investigated using disc diffusion and agar plate count methods. The MIC values of hexane, dichloromethane, chloroform, and butanol partitions and all fractions were calculated. Results: Fraction numbers 11, 4, and 7 showed the highest inhibitory effect with MIC value of 87 µg/mL, 156 µg/mL, and 156 µg/mL against E. coli, P. aeruginosa, and S. aureus, respectively. Conclusions: This study reveals that different fractions of P. australis have antimicrobial activities against various microorganisms.
Goethe on Color and Light
Authors: Grandy David ,   Institute for Interdisciplinary Research
Published: January 2021

Thiis essay explores Johann Wolfgang von Goethe*s reaction to Newtonian science and its quantification of nature. In particular, Goethe insisted that Newton's mechanistic portrayal of light and color was but a partial account of their reality. Broadening the understandings upon which science is practiced, Goethe developed ideas that presuppose mind-world intimacy and the consequent need to acknowledge the limited utility of mathematical modeling and theory construction. Such an approach values human subjectivity and sees it as partly constitutive of nature. While Goethe's treatment of color and light is not religious in a traditional sense, it resonates overtones consonant with religious belief. Rejecting the materialistic emphasis of Newtonian physics, Goethe felt that science may expand our spiritual horizons by helping us see the many ways we are patterned into the phenomenological splendor of the world This outlook aligns with Goethe's belief-illustrated in Faust-that the soul holds out for something more than a materialistic metaphysics.

Introduction SARS-CoV-2 has spread rapidly throughout the world. However, its ability to cause severe disease is not homogeneous according to sex and the different age groups. Objective To determine perinatal characteristics, morbidity, mortality, and serological results in neonates from seropositive pregnant women to SARS-CoV2. Methods We did a retrospective, descriptive, cross-sectional study. We included all newborns from positive pregnant women to SARS-CoV-2, between April 15 and May 10, 2020, who delivered in the National Perinatal Maternal Institute of Peru. The study extracted maternal and neonatal variables collected from the medical charts. The data were analyzed using descriptive statistics and Fischer's exact test. Results One hundred fourteen neonates were identified, 36.8% IgM/IgG positive for SARS-CoV-2, 7% IgG, and 56.2% had negative serology. The obstetric complications were premature rupture of membranes (14.9%) and preterm birth (8,8%). 8.8% of newborns had an Apgar score of less than or equal to six minutes, and of those, only one persisted after five minutes; three newborns died. There was an association between the type of maternal immunoglobulin and the serology of the newborn (p < 0.05). No association was observed between perinatal results and maternal immunoglobulin type (p > 0.05) or serological results in the newborn for SARS-CoV-2 (p > 0.05). Conclusion 43.9% of seropositive mothers' neonates to SARS-CoV-2 had a positive serological result, more frequently type IgM/IgG. 10.5% of the neonates had some morbidity, more frequent prematurity, low birth weight, and 2.6% died. Perinatal results were not associated with the type of immunoglobulin of mothers seropositive to SARS CoV-2; similarly, perinatal results were not associated with serological results in the newborn

Published: January 2021

Deforestation could influence land cover ecological significance in hunting grounds on a big scale. This research examines changes of forest and shrub patches in the Vojvodina region by a set of landscape metrics. The study area includes 154 hunting grounds from which hunting organizations are managing with 134 hunting grounds, PC "Vojvodinasume" with 17, Serbian Armed Forces with two, and National Park "Fruska gora" with one hunting ground. The results show that in the National Park and Serbian Armed Forces hunting grounds the broad-leaved forest areas occurred on the surfaces that were under the transitional woodland-shrub and vice versa. A similar situation is in the hunting grounds managed by PC ''Vojvodinasume'' where there is not only the most intensive logging of broad-leaved and coniferous forests but also the most intensive afforestation of mixed forests and transitional woodland-shrub. On the other hand, in the hunting grounds managed by hunting organizations, there is the highest area growth under the broad-leaved forest.

Authors: Radanov Pavle , Lešević Ivana , Brzaković Pavle , Pajić Dragan
Published: January 2021

In the Republic of Serbia, on March 15 th , 2020 Government decided to declare a state of emergency due to the Covid-19 pandemic. One of the measures was a movement ban for people over 65 in urban areas and those over 70 in rural areas. This research should indicate how people over 65 in urban areas have endured this situation, especially in relation to the same population in rural areas, as well as implications of the movement ban on the quality of life of the elderly population. Special importance is given to the rural population engaged in agriculture. A tool of data collection in this research was anonymous survey. Respondents' answers were statistically processed, which led to clear conclusions about the large negative consequences for the elderly population, including the agricultural activities in rural areas. Covid-19 is still present, which opens further questions related to the quality of life of the elderly population, if necessity for similar measures recurs in the future.

As Denmark is seen as a primer European and Global nation in achieving the United Nations' targets, Romania can use this example as a guideline on how to act and to obtain the most notable results. The article proposes some key principles that Romanians could follow in order to successfully fulfill the 2030 Action Plan having, as an example, the strategies and indicators reached by Denmark. The current work paper is structured as a review of the two reports that voluntarily summarize the situation of the Sustainable Development Goals in each state, followed by a statistical analysis of investment behavior and concluded with an analysis of the most notable differences between the states based on the dataset published by Eurostat.
An overview of the architectural activities of Jovan Đ. Ilkić in Belgrade
Authors: Andrić Dunja
Published: January 2021

Architect Jovan Ilkić is perceived in current historiography as a significant cultural emancipator and one of the leading figures in Serbian pre-WWI architecture. With his broad academic education, thorough knowledge of different architectural styles, and the great quality of his architectural compositions, he managed to distinguish himself as an authority, whose attitudes and opinion were deeply respected. He had no preference for a single style, rather applied the principles of Academicism, late Romanticism, Neo-Byzantine style, and Art Nouveau, producing some of the finest architectural pieces in Belgrade and Serbia. The aim of this paper is to expand and deepen the knowledge of Ilkić's work, and possibly raise some issues or present points of view which would shed new light on the subject. The focus will be on the architect's designs erected in Belgrade, with descriptions of major structures.

In this paper, the influence of thermal fixation of woven interlining on the quality of woven fabrics, evaluated from the aspect of their dc volume electrical resistivity, was investigated. The plain weave fabrics made from cotton, flax, viscose, polyester, and cotton/polyester blends and 3/1S twill weave fabric obtained from cotton and polyester fibers blend were investigated. A cotton fabric with a point-applied thermoplastic binder was used as an interlining. The obtained results showed that the dc volume electrical resistivity of fabrics is influenced by their chemical composition, type of weave, type of yarn, fabric density which is especially pronounced in the interlining, the process of thermal fixation of the interlining, and ambient air humidity. The thermal fixation of the woven interlining greatly reduces the dc volume electrical resistivity of polyester fabric (499 times in the warp direction and 860 times in the weft direction), and increases the resistivity of other fabrics in the range of 1.3 times for viscose fabric and fabric obtained from cotton and polyester fibers blend in plain weave to 3.9 times for twill weave fabric. Based on the conducted investigation, it can be concluded that the quality of the tested fabrics evaluated from the aspect of their electrical resistivities, was significantly improved in the case of polyester fabric i.e worsens in the other investigated fabrics after thermal fixation of the woven interlining.
Dyeing of textiles with natural dyes

In recent years there has been a great interest in the application of natural dyes in dyeing textiles due to their biodegradability and high compatibility with the environment. According to the experts, there is a great potential for using natural dyes to the extent that in some areas they can very easily replace synthetic ones. This paper reports the studies available on the characterization, classification and analysis of natural dyes; extraction of dyes from onion's outer shell and effects of different mordants and mordanting methods on the color shade. From an environmental point of view, replacing synthetic dyes with natural ones is not only a strategy to reduce risk and pollutants, but also an opportunity for new markets and jobs.

Mr. Arthur R. Colburn, an attorney of Washington, D. C., has taken as his recreation the study of the Pythagorean theorem and its proofs. He started with a knowledge of but two proofs, those of Pythagoras and Euclid, and has rediscovered a good share of the well-known proofs, and a number of others, some of which are little known, if not entirely new.
Educational Values in Mathematical Teaching
Authors: Hawkes H. E.

Any member of the teaching profession—a profession which is closely bound by the demands of routine work—is likely to be tempted either to assume radical and extreme views, or else to become stereotyped and to follow tradition. Just which direction any individual will follow is largely a matter of temperament. But either extreme usually betokens a failure to see things in their true relations, and in the proper perspective.
What Should be the Essentials of a Course in Mathematics for Elementary Schools in New York City?

Our individual answers to this question are largely controlled by our individual opinions, in which school tradition, or vocational demands, or mere predilection enter as largely determining factors. As yet we are not in possession of a sufficiently large body of scientifically treated data dealing with mathematical courses of study which we may use as norms for the determination of our answer. However, opinions on a particular subject of this kind are still of value in so far as they are based on intelligent experience with the factors specifically involved.

The Art of Teaching: An Experiment in the Teaching of Geometry
Authors: Fowler Wynette
Published: January 2021

For the school year of 1944-45, 1 was to have only geometry classes. I felt the need of some decided change in the methods of approach to the subject as well as in the results I had obtained before. The exasperation I had felt when students, who were perfectly capable of doing some original work, were satisfied to copy from the book or memorize what was given there led me to try a plan where the text was not given to each student, but used only as a classroom workbook. Thus, during the summer of 1944, after considerable research and study, I decided to combine some ideas from my study with those from my own experience into an outline for the course in geometry which I was to teach. In view of the results of the first year, the same plan was followed in 1945-46.
Dynamic Geometry

In 1938 Lloyd wrote: “Traditionally, geometry has been studied in the tenth grade as a system of rigid, non-flexible elements. The author advances the thesis that all geometric diagrams should be assumed as flexible linkages. …” The writer felt that the use of motion made the geometric materials more lifelike and, hence, more interesting, He also believed that many geometric properties were elucidated more clearly by the flexible models than by similar static ones. Finally, he pointed out that the variance and invariance of certain geometric elements were more easily demonstrated by jointed rather than fixed devices.
History of the Derivative and Integral of the Sine
Authors: Boyer Carl B.
Published: January 2021

The early development of the sine function was geometric rather than analytic. In ancient Greece the function concept and the ideas of differentiation and integration were not given formal expression, but the equivalents of these notions were implied by a number of problems in geometry. The determination of the length of a chord in a circle subtending a given angle x, for example, was the Greek equivalent of finding the value of the function 2 sin x/2. The method of exhaustion was the Greek geometric counterpart of finding an area by integration; and the kinematic determination by Archimedes of the tangent to his spiral is tantamount to the differentiation of a function. The calculus of the sine, however, could not at that time be given in terms of the now customary area and slope interpretations inasmuch as the sine curve was then unknown. Nevertheless, there are in the works of Archimedes several propositions analogous to the determination of the integral of the sine.
Functional Competence in Mathematics—Its Meaning and Its Attainment
Authors: Betz William
Published: January 2021

A college professor has said that if all the statisticians and economists of the nation could be laid out in a straight line, end to end, they would not reach a conclusion. Experienced classroom teachers will readily admit that this disconcerting opinion applies even more strongly to our educational policymakers. Their chronic inability to agree on a definite program for any length of time, or else the haste with which they often disavow the very plans they acclaimed so enthusiastically only yesterday, has reduced the edutional scene to a condition bordering on chaos. Externally, to be sure, we have much to be thankful for. Magnificent new school buildings have been constructed. The public support of education is becoming more dependable. Enrollment figures have risen to spectacular heights. Our children and young people usually like to go to school. On the whole, they are satisfactorily nourished and their health is carefully guarded. These are all great accomplishments.

Algebra Problems and Problems in Life

Thesis I of the Second Report of the Commission on Post-War Planning1 says, “The school should guarantee functional competence in mathematics to all who can possibly achieve it.” Then follows that very useful check list, composed of 28 items, as an aid in determining whether the student has achieved functional competence. There has been a great deal of controversy over the interpretation of the two key words, “functional” and “competence.” This is to be expected, since both words are variables and, if one supplements the other, the range may be great. In my opinion, our mathematics, to be functional, must be adequate to fulfill our needs both now and in the future. This means that each individual will place a different demand on methametics.

Enrichment of Mathematics Teaching

One day I was riding along a street with the principal of one of the high schools of a mid-west city. The traffic signal flashed red and I stopped my car at the intersec-section. The five o'clock pedestrianscrossed in front of us. Down from the curb stepped a long, stooped man wearing a crumpled suit, a battered hat, and unpolished shoes. He was not old, but he seemed scarcely an integral part of the life about him. He looked very much like a man with whom I had once attended college. “Look at that man with the tie hanging below his collar,” I said. “He looks like a man I once knew.” “His name is John White,” said my friend. (I substitute this fictitious name for the true one.) “He was once a teacher. Now he is a struggling third-rate lawyer.” “John White,” I repeated. “Then it is my old school mate.”
