The Conceptual Survey of Electricity and Magnetism (CSEM) has been widely used in the field of physics education. However, to date, no study presents a version of the test in Spanish. This article has three general objectives: 1) to present the CSEM in Spanish and analyze its reliability and discriminatory power, 2) to perform a detailed analysis of the most frequent difficulties of the students in the concepts evaluated in the test, and 3) to establish recommendations for research and instruction of these concepts. The test was implemented to 310 students who finished an Electricity and Magnetism course in a Mexican university. Researchers or physics professors from Spanish-speaking countries may use the test in Spanish that we present in the PhysPort project (physport. org); and the analysis and recommendations for instruction in this study.

El artículo aborda la trayectoria de Gaz Franco-Belge. Robert Lesage et Cie. (Cie. Franco-Belge), fundada en Bélgica en 1880, en Sanlúcar de Barrameda. En 1883, se inauguró la iluminación pública de gas y en 1919 cesó su actividad. Esta iniciativa corresponde a una generación efímera de empresas gasistas de matriz extranjera de ámbito municipal. En apariencia, se inscribiría en una tanda de inversiones poco razonables en mercados urbanos insuficientemente desarrollados, que acabaron de liquidar la competencia con la electricidad y las restricciones a las industrias consumidoras de carbón durante la Gran Guerra. Aquí, se defiende que el "privilegio" exclusivo de iluminación pública fue en realidad una condena en tanto el Consistorio se convirtió en el usuario principal y, al mismo tiempo, en la única fuente de regulación del mercado gasista en la ciudad. Sin intención ni de aumentar los impuestos ni de pagar este servicio público, se anclaba a las empresas concesionarias a negocios poco rentables, en localidades con rentas medias bajas.
This article focuses on the trajectory of Gaz Franco-Belge. Robert Lesage et Cie (Cie Franco- Belge), founded in Belgium in 1880, in Sanlúcar de Barrameda. Public gas lighting was inaugurated in 1883 and the company ceased its activity in 1919. This initiative may be included in an ephemeral generation of foreign companies in charge of municipal lighting. Apparently, these foreign direct investments were unreasonable where urban markets were underdeveloped. Competition with electricity and the restrictions on coal consumption during World War I finished with these firms. Actually, the exclusive “privilege” of public lighting was a sentence as long as the town Hall became both the main user and the only source of market regulation. Without any intention of either raising taxes or paying for this public service, the councils anchored concessionaires companies to unprofitable businesses, in localities with a very low income average.

Gas, electricidad, consumo, España, Electricity, Consumption, and Spain
- Abstract
-
En este trabajo se aborda el estudio de dos energías básicas, gas y electricidad, desde la perspectiva de la demanda y bajo un enfoque comparativo. La fuente a utilizar será la Estadística del Impuesto sobre el consumo de luz de gas, electricidad y carburo de calcio, complementada/contrastada con otras (Estadística Minera, Datos estadísticos técnicos de las fábricas de gas españolas, monografías locales, etc.). Los principales aspectos que se tratarán serán su difusión geográfica, incardinándola en la modernización de las estructuras urbanas, y los niveles de gasto energético, insertado a su vez en los cambios generales de las pautas de consumo, ambos desde una doble perspectiva espacial y temporal. Todo ello se llevará a cabo en un marco cronológico clave, el primer tercio del siglo XX, lo que permitirá abrir nuevas perspectivas y debates acerca del modo concreto en que se llevó a cabo en España el proceso de transición energética del gas a la electricidad.
This paper deals with the study of two basic energies, gas and electricity, from a demand perspective, and under a comparative approach. The source that will be used is the Estadística del impuesto sobre el consumo de luz de gas, electricidad y carburo de calcio, which is complemented/ contrasted with others (Estadística Minera, Datos estadísticos técnicos de las fábricas de gas españolas, local monographs, etc). The main issues will be their geographical diffusion, placing it in the context of the modernization of urban structures, as well as the levels of energy expenditure, which are linked to the global changes in consumption patterns, both from a spatial and temporal perspective. All this will be carried out in a chronological framework, over the first third of the twentieth century, which will open new perspectives and debates about the specific way in which the process of energy transition from gas to electricity was carried out in Spain.

- Abstract
-
En 1934, 672 empresas eléctricas de toda España publicaron en los Boletines Oficiales provinciales y en el Butlletí Oficial de la Generalitat de Catalunya sus precios de venta de la energía destinada a fuerza. Estos datos nos permiten disponer de una información muy completa de los sistemas tarifarios utilizados por los productores y distribuidores de electricidad antes de la guerra civil así como también de los precios máximos y de los descuentos que ofrecían a sus clientes. En este artículo se analizan los precios y descuentos publicados desde una doble perspectiva, empresarial y territorial, con objeto de conocer el precio de la energía eléctrica para usos industriales en la España del momento. Las notables diferencias observadas en el precio de venta del kWh reflejan la existencia de un mercado eléctrico escasamente integrado y el importante papel que seguían desempeñando los pequeños y medianos productores y distribuidores de energía a la hora de suministrar fluido a miles de empresas de todo el país en vísperas de la Guerra Civil.
In 1934, a total of 672 electricity companies from all over Spain made public in the Boletines Oficiales of the provinces and in the Butlletí Oficial de la Generalitat de Catalunya their rate systems and selling prices for power. These data provide comprehensive information about the diverse pricing system used by producers and distributors of electricity in Spain before the Civil War as well as the maximum prices and discounts offered from them to their clients. This paper analyses these prices and discounts from a business and territorial point of view. The remarkable differences in the selling price of kWh among firms and places reflect the existence of a poorly integrated electricity market and the important role small and medium producers and distributors of energy still played when supplying electricity to thousands of consumers around the country on the eve of the Civil War.

Aquesta tesi se centra essencialment en l'estudi de dues variables: el llenguatge de dos llibres de text quant a si afavoreix o no la comprensió explicativa, i les respostes dels estudiants quan s'utilitzen altres fonts d'informació complementària. La mostra pertany a dos països: Canadà i Pakistan, i com a metodologia es va utilitzar l'anàlisi documental i un disseny quasiexperimental. Els resultats apunten a la necessitat de millorar els llibres de text i el seu ús.
This thesis focuses primarily on the study of two variables: the language of two textbooks as to whether or not favors explanatory understanding, and the responses of the students when they use other sources for additional information. The sample belongs to two countries: Canada and Pakistan, and document analysis as a methodology and a quasi-experimental design was used. The results point to the need to improve textbooks and usage.

- Abstract
-
La historia de la Compañía Eléctrica Mengemor durante la Guerra Civil Española (1936-1939) es interesante, ya que era una de las grandes eléctricas del país, y su dirección e instalaciones quedaron divididas hasta el final de la contienda, y buena parte de las mismas en el frente de batalla. Para cada bando (el republicano y el nacional) analizaré: quiénes y cómo la dirigieron, el estado de las instalaciones, cómo se repararon y la electricidad producida. En general, ésta creció en ambas zonas, gracias a la gestión realizada y los escasos daños sufridos.
The history of the electric company Mengemor during the Spanish Civil War (1936-1939) is interesting in that it was one of the main electric companies in Spain, and its management and installations were divided during the conflict, and a large part of these were on the front line. For each side in the conflict (the republicans and the nationalists) the following will be analyzed: how they were managed and by whom, the state of the installations, how they were repaired, and the electricity which was produced. In general, production grew in both zones. This can be explained by good management and the scarce damage inflicted on the installations.

KOSOVO (Republic) -- Politics government, NORTH Atlantic Treaty Organization, MILOSEVIC, Slobodan, 1941-2006, ELECTRICITY, ECONOMIC competition, KOSOVO (Republic), and SERBIA
- Abstract
-
The Kosovo, Serbia settlement negotiated by the G-8 countries is cause for relief but not celebration. The provocative withdrawal of humanitarian observers and North Atlantic Treaty Organization's (NATO) bombing enabled Prime Minister Slobodan Milosevic to accelerate the Kosovar expulsions radically. The new arrangement confers only a vague promise of "substantial autonomy," and Yugoslavia retains sovereignty over Kosovo indefinitely. The state-by-state battle over the nation's $206-plus-billion-a-year power business reached critical mass when California brought competition to its electricity markets in 1998. Ohio has proven unexpectedly ferocious in resisting this utility blackmail.

THEATER, FESTIVALS, MELODRAMA, ELECTRICITY, EVICTION, and COMEDY
- Abstract
-
The article presents information about theater. For half its twenty-four season span of existence, the Actors Theater of Louisville has been home annually to the Humana Festival of New American Plays. Several plays have been shown in this festival. "The Queen of the Leaky Roof Circuit," limits itself to the threat of eviction, and does not deal with its consequence. Amazingly, even with this standby of melodrama, Breslin generates something less than fifteen watts of theatrical electricity. "Alone at the Beach," is a perfectly crafted light romantic comedy by dramatist Richard Dresser.

- Abstract
-
The article presents information on demand for science in the Great Britain. The demand for electricity in Great Britain has doubled every nine or ten years since 1900, in other words, it has increased at about 8 per cent compound interest for more than sixty years. Such doubling and redoubling in equal intervals of time is termed by mathematicians and scientists an exponential growth. The number of practicing scientists in the world seems to double every ten years or so. In fact, of all the scientists who have ever lived, three-quarters are alive and practicing their today.

-
This article focuses on solving water shortage problem. In this article, the author presents a case of large-scale nuclear-power plants, which would produce both low-cost electricity and fresh water from the sea. Since considerable opposition has developed even to the medium-sized nuclear powered electric generating stations that have been projected for a number of locations around the country. In every technological development, and likewise in the opposition to it, different intellectual levels can be discerned.

- Abstract
-
All the major sources of power which man has tapped--coal and steam, electricity, the internal combustion engine--have also brought society up against new dangers. Atomic energy for the first time faces man with dangers which affect not only the present population of the earth but also their remote descendants, who must inherit their biological characteristics through genes which are liable to be permanently damaged. The radioactive dust liberated in experimental explosions is only one such hazard, but it is perhaps the most difficult to handle.

UNITED States -- Politics government, ELECTRICITY, CONSUMER behavior, INTERNATIONAL relations, CUBA, and UNITED States
- Abstract
-
This article presents information about political developments in the U.S. as of April 19, 1933. The public is becoming aware of the power problem. The restricted use of electric power due to its high cost has been--in large measure responsible for--the supleness of the consumers. Here is at present every reason to suppose that the Black bill, instituting a thirty-hour week, which has passed the Senate by a vote of 53 to 30, will be enacted into law. The American government extended substantial aid in the establishment of the new government and by granting tariff reciprocity, which, while benefiting the Cubans somewhat, was decidedly advantageous to American sugar producers.

- Abstract
-
This article focuses on various issues related to politics. The coal shortage which confronts the U.S., and which threatens to bring on a fuel famine next winter for more than one community and even for large sections of the country, is only the American phase of a problem which is staring in the face every country in Europe and bids fair to interfere seriously with the conduct of military operations. As far back as August 20, 1918, the Coal Controller Guy Calthrop, in an address at the conference of the British Miners' Federation, stated that he was faced with a shortage of 36,000,000 tons a year.

- Abstract
-
The article focuses on various restrictions due to power shortage in France. Theatres, concert halls, and moving-picture houses, with a few permitted exceptions, are open only on Thursday, Saturday and Sunday. There are virtually no evening lectures or meetings of any sort, save a few on the evenings on which the theatres are open. If one goes out to dinner, he must get home by ten, or else walk, for cabs are hard to find at night after that hour. The supply of gas and electricity is rigidly limited, and any excess consumption of gas is charged for at a rate which amounts to a prohibitive fine. According to the author, the prime reason for these various restrictions is the scarcity of coal, in itself a matter of great importance.

The article focuses on the atomic-energy power industry of the U.S. The Enrico Fermi atomic-power plant originally erected as a technical showcase for the nuclear-power industrial and scheduled to bring electricity to the Detroit metropolitan area in 1960. But three AFL-CIO unions have filed a court action blocking its completion and threatening to disrupt development of the entire atomic-power industry. Last June the U.S. Court of Appeals agreed that the plant might prove a menace to the health and safety not only of its employees, but also to residents of nearby Detroit.

- Abstract
-
The article comments on the present muscle-bound condition of the U.S. From the northern tip of Maine to San Diego, California, the country is suffering from a shortage of electricity for light and power. Power companies know this shortage may have political consequences. That much is obvious from their desperate efforts to keep the facts from the public. The great California utility network of Pacific Gas and Electric had said early in 1947 that its customers had nothing to worry about, the company could take care of the demand even in the driest year. The new emergency power director immediately announced power cuts of 20 per cent along with various forms of rationing, including orders that housewives must not put hot food into refrigerators.

- Abstract
-
For a number of years no towns in the United States having population of from 50,000 to 100,000 with the exception of three or low resort towns like Miami, Florida, and Little Rock, Arkansas, had higher electric rates than Sioux City, Iowa. In the meantime, until the municipal plant is in operation, the thousands of dollars paid every day for electricity and gas in Sioux City will go to pay interest on $9,531,300 of bonds and $4,838,700 of 7 per cent preferred stock of the Sioux City Gas and Electric Company, besides $2,900,000 of common stock, a great deal of which is admitted to be "water." Until the relief of municipal ownership is obtained, the public will continue to pay and pay and pay.
