Multiscale Experiments and Multifractal Analysis of Bituminous Coals: Dominant Pore Properties for Gas Permeability
Authors: Zhang Bo , Zhu Jie , Jiang Yaodong
Published: August 2018

The pore characteristics of coal are highly correlated with gas permeability. In this study, multifractal analysis based on mercury intrusion porosimetry (MIP) was used to investigate the pore spatial distributions and heterogeneity of pore size distributions (PSDs) of three sister coal samples collected from the Xin Zhouyao mine in China. The mercury intrusion data, under pressures of over 10 MPa, were corrected in combination with the gas adsorption results. All CT images were processed by using the Image-Pro Plus® (IPP) software (Media Cybernetics, Inc., Rockville, MD). The pore volume percentage information obtained from the MIP was found to be coincident with the 3D reconstructions. Seepage experiments were also carried out under different gas pressures to analyze the effect of the pore parameters on permeability. The results from these experiments showed that for the three coal samples, the degree of clustering of the pores is the dominant factor for permeability and should be the first factor considered. Variations of μ (q, ϵ) versus ϵ indicated that the PSDs of coals have multifractal behavior. Multifractal analysis was suggested by the extracted parameters from the PSDs, including the capacity dimension D0, the information dimension D1, the correlation dimension D2, the widths of the right side D0–D10, and of the left side D−10–D0 of Dq spectra, and the widths of left side α0–αq+ and right side α0–αq− of the f (α) spectrum. These parameters were further discussed to evaluate the permeability.
Impact of Outdoor Exposure on the Performance of Insulating Glass Unit Primary Sealant: A Case History
Authors: Booth Rebecca R. , Hoigard Kurt R. , Johnson Dennis K. , Klosowski Jerome M.
Published: August 2018

The flowing movement of lightly colored polyisobutylene (PIB) primary sealant into the interpane space of in-service insulating glass units (IGUs) is a phenomenon we have encountered at multiple locations in the United States. This behavior has resulted in the accumulation of visible deposits within the exposed field of the IGU in excess of the dimensional limits recommended by insulating glass manufacturers and industry standards. Such conditions create aesthetic and potential long-term durability concerns and attribute to the failure of the PIB material to perform in a durable manner. Flow of the PIB material has been observed to occur when standard practices and materials were used during IGU fabrication and glazing operations and when the IGUs were exposed to common environmental conditions. This paper discusses contributing factors to the PIB flow phenomenon we observed. The data garnered from observations and analysis revealed a correlation of PIB flow with IGU solar exposure and consequential effects on material properties. Chemical analysis of PIB samples removed from affected in-service IGUs indicates physical changes occurred that correspond with changes in the material at the molecular level. Locations of PIB flow correlated well with areas of increased solar exposure and isolation from interior conditioned air.
Case Study: Using Sealants and Spray-Foam Insulation to Create a Continuous Air Barrier from the Interior of Existing Buildings
Authors: VanDommelen David M.
Published: August 2018

The continuity and integrity of air-barrier systems play a critical role in the performance of exterior envelopes in controlling airflow and vapor transmission. Continuity is essential, particularly in locations along the coast where climates with elevated humidity and high winds exist. In new construction, a continuous air barrier can be achieved by applying materials on the exterior of wall systems, including sheet membranes, fluid-applied membranes, rigid insulations, and spray polyurethane foams (SPF). This method is generally preferred due to the ease of installation and limited detailing concerns. However, in developing and implementing repairs for existing buildings, the application of an air barrier can require repair solutions from the interior due to site conditions, budget constraints, building occupants, or other factors. Sealants, in combination with SPFs, have been successfully utilized in the creation of interstitial (cavity) air-barrier systems along exterior walls. After the construction of three mid-rise multifamily condominiums located in Morehead City, NC, interior damage related to air infiltration began to be reported by building occupants and maintenance staff. Issues included microbiological growth on interior walls and ceilings; condensation along ductwork, registers, and exhaust vents; and air infiltration around windows, electrical fixtures, and wall terminations. The investigation to determine causes of air infiltration, as well as the development and implementation of repairs, are discussed herein. The investigation revealed inadequate detailing around window openings and penetrations in the building envelope, along with incomplete construction of the exterior walls and walkway expansion joints. The improper construction allowed unconditioned exterior air to infiltrate the building envelope. Repairs to create a continuous air barrier included sealing of exterior walls, ductwork, joints between wall framing members, and expansion joints with sealants and SPFs from the interior along with localized reconstruction of exterior walls. Isolated repairs to the existing weather barrier and flashings were also implemented to address moisture infiltration issues.

Authors: White Christopher C. , Hunston Donald L. , Pintar Adam , Filliben Jim
Published: August 2018

Determining design life in less than real time has eluded researchers for decades. ASTM has recently issued a new standard, ASTM C1850, that outlines a procedure for developing accelerated testing methods to determine the design life of a sealant. This paper will use this new standard as a template to examine the ongoing research at NIST. The results will demonstrate where significant progress has been made.

LA FILOSOFÍA NUESTROAMERICANA EN LA FILOSOFÍA CHILENA: UNA MIRADA A LA SEGUNDA MITAD DEL SIGLO XX
Authors: Ahumada Infante Aldo
Published: August 2018

El término nuestroamericano —utilizado por Horacio Cerutti— tiene sus fundamentos en el concepto "Nuestra América". Este hilo conductor de pensamiento tiene como hecho ineludible el hacerse cargo de la realidad en que se vive y del lugar en donde se está, hecho expresado en un permanente interés en la identidad cultural y nacional, como también por una lectura crítica y explicativa del desarrollo de las ideas. En el caso de Chile, a nuestro juicio, la memoria filosófica nuestroamericana ha tendido a ser borrada, olvidada, siendo obnubilada por un fuerte eurocentrismo, lo que ha dado como resultado un escaso número de filósofos preocupados por "lo latinoamericano". Así, este trabajo indaga sobre los orígenes de la vertiente latinoamericanista en la filosofía chilena en la segunda mitad del siglo XX. A modo de conclusión, proponemos que no es sino hasta los años ochenta cuando, desde el Círculo de Filosofía de la Academia de Humanismo Cristiano, se genera un punto de inflexión con la tradición filosófica chilena, dando origen de forma más nítida a la vertiente nuestroamericana que, antes de esto, solo habría tenido pequeñas huellas dispersas.

HISTORIA DE LA FILOSOFÍA CATÓLICA EN CHILE DURANTE EL SIGLO XX
Authors: Caiceo Escudero Jaime
Published: August 2018

A partir de investigaciones realizadas en la Universidad Católica de Chile entre 1979 y 1984 se pudo constatar la creciente influencia que la filosofía católica tuvo en Chile desde fines del siglo XIX y primera mitad del siglo pasado, producto, especialmente de la influencia que la Encíclica Aeterni Patris de León XIII, promulgada en 1879, y la acción que la propia Universidad Católica, tuvo en la intelectualidad católica chilena. De esta forma surgieron destacados pensadores chilenos que desde una perspectiva de pensamiento católico incursionaron en la metafísica (Lira Pérez, Finlayson, Gandolfo y Martínez), en la difusión de la filosofía cristiana (Miller, Restat, Escudero, Larson, Silva, Rosales y Jiménez), en la filosofía del derecho (Peragallo y Lira Ulrquieta), en la filosofía política (Frei, Castillo y Bustos) y en la filosofía de la educación (Hurtado); la mayoría hace su análisis y aporte desde el tomismo o desde el neotomismo (Maritain), sin descuidar el diálogo con otras posturas y filósofos de otras posiciones.

PROYECCIONES DE ALBERT CAMUS: EL ABSURDO Y LA REBELIÓN COMO EXPERIENCIAS DEL LENGUAJE
Authors: Rivas Nielsen Niels
Published: August 2018

Absurdo y rebelión son dos conceptos fundamentales dentro de la obra de Albert Camus. En el terreno filosófico su significado ha sido ampliamente estudiado y debatido. Por lo mismo, este artículo tiene como propósito abordar ambas nociones desde una perspectiva distinta, planteando que tanto absurdo como rebelión pueden ser entendidos como fenómenos o experiencias verbales. Dado este enfoque, el estudio propone una relación entre los planteamientos de Camus y autores cuyas obras exhiben una actitud radicalmente crítica y experimental hacia el lenguaje: Samuel Beckett, Alejandra Pizarnik, Oliverio Girondo, entre otros. El estudio se ocupa de identificar y fundamentar esas conexiones, sobre la base de una pregunta esencial: ¿qué consecuencias tiene la experimentación y transformación del lenguaje?
EL SUICIDIO EN LA HOGUERA. CAMUS Y LA PENA CAPITAL
Authors: Trujillo Iván
Published: August 2018

Es conocida la oposición de Albert Camus a la pena capital. En sus Réflexions sur la guillotine (1957) va a criticar la máquina judicial que hace sufrir en el tiempo y en el espacio al condenado a muerte. Antes, en L'homme revolté (1951), ha criticado la perversa lógica contractual rousseauniana implicada en la auto-imputación que conduce silenciosamente a Saint-Just al patíbulo en la época del terror revolucionario en Francia y a los condenados a muerte en la purgas del régimen de Stalin en la Unión Soviética. Pero unos años antes, en El Mito de Sísifo (1942), hablando del suicidio, se ha referido a Galileo y al peligro que ha corrido de morir en la hoguera por defender sus verdades. Nos preguntamos aquí por aquello que, en el pensamiento de Camus, convierte a la pena capital en suicidio.

Authors: Carvalho Thaís Ramos de , Barham Elizabeth Joan , Souza Carolina Duarte de , Böing Elisangela , Crepaldi Maria Aparecida , Vieira Mauro Luís
Published: August 2018

Abstract Coparenting refers to mothers and fathers articulating their efforts to raise their children. Currently, there are no instruments to measure this construct in Brazil. In this study, the adequacy of a cross-cultural adaptation of the Coparenting Relationship Scale (CRS) (Escala da Relação Coparental - ERC) was evaluated, examining evidence of semantic, conceptual, cultural, idiomatic, operational and measurement equivalence, and face validity. Two independent research groups adapted the CRS and then produced a unified version, completed by 171 couples with at least one child between 4 to 6 years of age. The precision of the subscales, measured using Cronbach’s alpha, varied between .16 - .83. Four subscales had good precision in the Brazilian sample, but the precision of the “Division of Labor”, “Coparenting Closeness”, and “Coparenting Agreement” subscales needs to be improved and additional evidence of the validity of this instrument must be examined, so the CRS can be used in Brazil.

Published: August 2018

Resumo Diante das alterações rápidas e constantes da sociedade contemporânea, observa-se um processo de redefinição/indefinição do papel paterno. Nesse sentido, objetivou-se compreender como pais inseridos em diferentes configurações familiares experimentam a função paterna, associando suas vivências ao desenvolvimento do self de suas filhas. Participaram da pesquisa oito díades pais-filhas de diferentes arranjos familiares. Foi realizada entrevista semiestruturada individual mediada por cinco cartões do Teste de Apercepção Temática Infantil (CAT-A), empregado de forma compreensiva. A estratégia metodológica foi a das “Narrativas Psicanalíticas”. Os resultados apontaram que os pais demonstram, de modo singular, pouca clareza quanto aos limites e às possibilidades do exercício de suas funções e deficiências para proporcionar um ambiente suficientemente bom para as meninas, principalmente no que se refere ao oferecimento de holding. Assim, destaca-se a importância não do arranjo familiar ao qual a díade pertence, mas das posições que a criança e o pai ocupam na família.

Predictive ability of accruals before and after IFRS in the Brazilian stock market
Authors: Boina Terence Machado , Macedo Marcelo Alvaro da Silva
Published: August 2018

ABSTRACT This study aimed to analyze and assess the predictive ability of discretionary accruals (DAs) and non-discretionary accruals (NDAs) for forecasting future cash flows before and after the convergence with International Financial Reporting Standards (IFRS) in Brazil. The study is warranted due to the scarcity of research in Brazil on the subject and is relevant because it aims to shed light on whether the changes occurring due to convergence with IFRS in Brazil have improved accounting quality. The accounting choices of managers and accountants in the Brazilian stock market, enabled by IFRS, contribute to an apparent improvement in accounting quality in terms of reliability, the faithful representation of entities’ equity and financial positions, and in particular, the predictive ability for forecasting future cash flows. The population was composed of publicly traded companies listed on the Bovespa and São Paulo Stock, Commodities, and Futures Exchange (BM&FBovespa) in 2004 to 2007 and 2010 to 2015. The non-probability convenience sample is composed of 715 enterprises, once companies from the “finance and insurance” and “funds” sectors and even those considered as “holding” were excluded. The data were pooled by year, as they contain different companies over the time series (unbalanced panel data). The DAs and NDAs produced prior to full convergence with IFRS are negative and statistically significant for predicting future cash flows in the Brazilian stock market, which indicated opportunistic/contractual earnings management. One of the possible explanations for this would be the influence of government tax authorities on Brazilian accounting norms, which could induce managers to manipulate accounting results with the aim of reducing earnings in order to pay fewer taxes, for example. The DAs and NDAs produced after IFRS are positive and statistically significant for predicting future cash flows in the Brazilian stock market, signaling the motivation of discretionary accounting choices under the informational aspect. Current DAs and NDAs add informational power compared to current aggregate accruals. It has also been observed that the current DAs and NDAs originating after IFRS in Brazil, compared to current aggregate accruals, have an informational gain in relation to those produced before.
Assessing educational leadership: a competence-complexity based test
Authors: Parreira Artur , Pestana Maria Helena , Oliveira Paulo
Published: August 2018

Abstract This study is focused on the validation of a leadership test, based on a complex model of leadership skills, as a tool for assessing teacher’s educational competence, viewed as important in conduting adolescent and adult learning classes. Its specific purpose is to establish the norms and interpretation criteria for the test, in educational contexts. The model highlights the skills for leadership effectiveness, in a definite cultural setting, the Academy of East Timor National Police, viewing leadership as an essential way of steering human systems. The postulates of the model hypothesize the positivity of leadership as a result from an appropriate combination of power and information, while executing the fundamental activities of dinamizing and controlling the performance and results of the learning ativities. The test was applied to a sample of trainees in an educational military context, the Academy of East Timor National Police. The results of their evaluations on each competence for leadership effectiveness were valid and reliable. Nevertheless, the authors plan to test this tool in other specific contexts, in order to complete the evaluation of the leadership complex set of competences required by educational contexts.
Democratizing the access to college education: Brazilian race/color classification in affirmative action’s debate
Authors: Teixeira Moema De Poli
Published: August 2018

Abstract One of the principal aspects to develop affirmative action in Brazil comprises how to define target population, which includes uses and perceptions of ethnic/racial/color categories. The present paper has the main objective of bringing the analysis about IBGE’s2 race/color classifications contribute to the design of affirmative action in Brazil using categories historically constructed with the endorsement of official statistics. The color issues in the Brazilian Census and the experiences, including the racial designation as an open response, has been studied since 1872, and it is noted that there are two dimensions to be observed in the affirmative action debate: a structural and other cultural involving race/color classifications in Brazil. The statistics are fundamental to build the best evidence in shaping public policy. On the other hand, we must recognize ethnic and racial identities as cultural phenomena that are susceptible to change, which drives us to continue the discussion, trying to capture the meaning of these transformations. The affirmative action debate may not disqualify any of these approaches to knowledge about race relations in Brazil.

RESUMO A presente pesquisa avaliou o potencial microbiano de uma biopilha na biorremediação de solos contaminados por hidrocarbonetos, montada em uma base de distribuição de combustíveis na região metropolitana de Porto Alegre, Rio Grande do Sul. Desta biopilha, foram avaliadas as concentrações dos hidrocarbonetos totais de petróleo (HTP) e de compostos benzeno, tolueno, etilbenzeno e xilenos (BTEX), em nove pontos, durante quatro etapas de operação e em três profundidades por ponto. De cada coleta, também foram reservadas amostras de solo para realização das análises microbiológicas. A partir dessas amostras, buscou-se identificar fungos e leveduras pela análise de suas estruturas reprodutivas em lâminas de microcultivo, e bactérias pela técnica da Reação em Cadeira da Polimerase (PCR) e sequenciamento do gene que codifica o RNAr 16S. Ainda, avaliou-se a capacidade dos microrganismos isolados em degradar óleo diesel comercial, utilizando o indicador redox 2,6-diclorofenol indofenol (DCPIP). Como resultado deste estudo, observaram-se elevados percentuais de redução nas concentrações de HTP e BTEX na biopilha, como 92 e 100%, respectivamente. Das amostras de solo da biopilha, foram isoladas 101 cepas de microrganismos, das quais foram identificadas 19 cepas de fungos filamentosos, 34 de bactérias e 1 de levedura. Os resultados evidenciaram a capacidade de alguns gêneros de fungos, como Aspergillus, Trichoderma, Penicillium, Cladosporium e Verticillium, e bactérias, como Bacillus spp. e Streptomyces sp., em degradar hidrocarbonetos constituintes do óleo diesel comercial.
Assesment of Power Quality Disturbances For Grid Integration of PV Power Plants
Authors: Bayrak Gökay , Yılmaz Alper
Published: August 2018

Power Quality problems, which have become an
important consumer issue in recent years, are defined as changes in voltage,
current, or frequency in the power system. Among the factors affecting energy
quality in grid-connected PV systems are island mode operation, current and
voltage harmonics, transients, flicker, interruption, DC offset, notches,
frequency changes, voltage sag / swell, voltage imbalances in the system and
power factor. Because of the power quality problems, several transmission and
distribution losses can occur due to both the consumers and the generators.
Also, the integration of PV power plants to the main grid will cause several
power quality problems, and a reliable operation of the grid with PV power
plants is a significant issue for distributed generation. Thus, the first step
in preparing a reliable algorithm for detecting power quality events occurring
in the current grid is to model a power system in which power quality
impairments can be analyzed. In this work, the power quality disturbances that
occur in the low-voltage grid that is fed through both the main grid and the
grid-connected PV system are modeled and investigated. Developed electric power
distribution model includes simulation of voltage sags caused by three phase
fault, transformer energization and asynchronous motor switching, voltage
swells caused by three phase fault, transients due to large capacitor bank
switching, harmonics and notches caused by the load connected via the power
converter. Examination of the power quality disturbances with simulation
clearly revealed the resulting waveforms, the response of the electrical power
system to the fault conditions. Another advantage of the realized study is that
the developed model can be used to measure the performance of the PV connected
distributed generation system in fault detection and classification studies.

It is observed that macroeconomic variables significantly impact stock prices depending upon the type of index. As per the Granger Causality test, the study found unidirectional relationship from Exchange Rate to BSE Small Cap; unidirectional relationship from Exchange Rate to BSE Mid Cap and BSE Mid Cap towards IIP; bidirectional relationship between BSE Large Cap and Exchange Rate whereas unidirectional relationship from BSE Large Cap to IIP and from Money Supply M3 towards BSE Large Cap.
Small RNA Sequencing using NEXTflex™ Small RNA-Seq Kit v3 from Bioo Scientific v1
Authors: D Mohammed Kevin , Hekmaty Saboor
Published: August 2018

GENERAL INFORMATION Product Overview The NEXTflex™ Small RNA-Seq Kit v3 can be used to prepare small RNA libraries from total RNA for Illumina-compatible next-generation sequencing. The NEXTflex Small RNA-Seq Kit v3 is designed to greatly reduce formation of adapter-dimer product in small RNA-seq library preparation, allowing completely gel-free library preparation from typical input amounts, or allowing libraries to be created from low input amounts with a PAGE-based size selection of the final library. This kit utilizes patent-pending adapters with randomized ends to greatly reduce sequence bias in small RNA sequencing library construction (1), allowing more accurate identification and quantification of microRNAs, piRNAs, and other small RNAs. This manual includes protocols for size selection using a gel-free (Step H1) or PAGE-based (Step H2) method. The gel-free protocol described in this manual is recommended for library preparations where a sufficient amount of ~150 bp product and no ~130 bp adapter-dimer product is seen after 16 cycles of PCR, which is typically achieved when using 1μg of total RNA starting material. Note: 1) This protocol can be adapted for compatibility with sequencing platforms other than Illumina. The sequences of the adapters (provided in Figure 1) and PCR primers must be modified for the specific sequencing platform. 2) This protocol is specific for version 3 of theNEXTflex™ Small RNA-Seq Kit: Bioo Scientific, Catalog # 5132-05 (8 reactions), or Catalog #5132-06 (48 reactions). Modifications to the protocol may be required for updated versions of the kit. References1.

Types of Inferences in the Comprehension of Metaphor
Authors: Pistol Ramona
Published: August 2018

This paper focuses on the cognitive processes involved in the comprehension of metaphors. It builds on current studies in cognitive linguistics by proposing an amendment to the theoretical idea that there are two routes for comprehending metaphors. It presents an account which is underlined by concept adjustment in all types of metaphorical instances, with the only difference being in the degree of the inferences that it requires. In this paper I claim that a conscious level of processing is involved in the comprehension of some metaphors in order to determine the speaker’s meaning. I ground my discussion squarely in the distinction between types of inferences developed by Mercier and Sperber (2017).
Theory and Practice of the Mini-bibliobattle as an Output Activity of Extensive Reading
Authors: Fujii Kazuma
Published: August 2018

The purposes of the present paper are (a) to propose the Mini-Bibliobattle as an appropriate output activity linked with the extensive reading (ER) program by discussing its theoretical background and (b) to explore the effects of the Mini-Bibliobattle on the change of reading attitudes through one case study. The current paper firstly reviews the previous literature on the outcome of ER and points out that little study has been done concerning how the input of English gained through ER can efficiently be connected to the development of the output ability. In this paper, the Mini-Bibliobattle, in which each participant makes a three-minute presentation on his/her favorite book, answers the questions by the audience, and decides a champion book, was proposed as an appropriate output activities of ER. Then its rationale was discussed from the two perspectives, i.e., continuity with ER and relatedness to ER. Additionally, a case study was conducted with 46 third-year technical college students to investigate the effects on their reading attitudes. This case study found that (a) the participants came to read English more carefully than before (b) they came to expand the range of book selection and (c) most participants recognized that the Mini-Bibliobattle was a meaningful activity for their output ability development.
A Critical Discourse Analysis of Donald Trump’s Inaugural Speech from the Perspective of Systemic Functional Grammar
Authors: Chen Wen
Published: August 2018

As an interdicipline that studies the relation of language, power and ideology, critical discourse analysis has attracted more and more linguists’ attention, which can be applied to analyze language features under certain social and cultural background. Critical discourse analysis is based on Halliday’s systemic functional grammar that is a practical method to analyze discourse. Political discourse as a kind of typical discourse which involves the speaker’s ideology and intention, can also be analyzed by critical discourse analysis. Therefore, this paper analyzes Donald Trump’s inaugural speech mainly from the perspectives of transitivity, modality, personal pronoun and coherence in order to reveal the speaker’s political intention, and help readers understand the meaning of discourse, cultivate their critical consciousness and analytical ability. The paper concludes that Trump uses different language forms to transmit, change and maintain audiences’ ideology subtly. At the same time, it has a positive effect on the development of the critical discourse analysis.
Responses to the Greeting ‘How Are You?’ in Britain and America
Authors: Chen Mengyi
Published: August 2018

This study compares the responses to the greeting “How are you?” (“HAY?”) in Britain and America. By using a database derived from the spoken corpora of BNC and COCA, this study aims to explore the universal and regional-specific features of people’s response to “HAY?”, including their wording and pattern choosing. Adopting Sacks’ (1975) notion of “value states”, the result shows that responding with “value states” is the commonest pattern to answer “HAY?”, and neutral responses are most frequently used. In terms of regional differences, British people respond to “HAY?” conservatively, using “not bad” to express “good”, while Americans directly use “good”. What’s more, British like to combine “value states” with thankings, while Americans use more reciprocity questions, reflecting British’s gentleness and American’s openness. Other response patterns and register differences are discussed in the article.

A területi egyensúlyok
Authors: Bartke István
Published: August 2018

A területi egyensúlyi növekedés – nemzetközi fogalomhasználat szerint – a különböző régiók eltérő fejlettségi színvonalának közelítésére ható folyamat, vagyis a kevésbé fejlett területeknek a fejlettebb régiókét meghaladó ütemű növekedése. Ez a felfogás a területfejlesztési politika működési körét a gazdaságra szűkíti le. E hibaforrás megszüntetésére olyan modell készült, amely a koncepcióalkotásba szélesebb társadalmi szférákat is bekapcsol.

Egy nagyváros helyzete az információs társadalomban
Authors: Barsi Boglárka , Csizmadia Zoltán
Published: August 2018

A napjainkban zajló fejlődési folyamatok fő motorja az információs technológia, amely az elkövetkező évtizedekben a legnagyobb ipari szektorrá válhat. Ez a folyamat azonban óriási társadalmi kihatással jár együtt Magyarországon is, ahol napjainkban éljük át az információs társadalomba vezető átmenetet. A magyar városhálózat gerincét alkotó megyei jogú városok között éles verseny folyik új befektetők megnyeréséért, új igazgatási és adminisztratív funkciók megszerzéséért. Az információs társadalom új versenyhelyzet elé állítja Magyarországot, így a városhálózatot is. Ezért is fontos az egyes nagyvárosok helyzetét a többi megyei jogú városhoz viszonyítva megvizsgálni, hogy pontosabb képet nyerhessünk az egyes városok információs társadalomban betöltött szerepéről.

Távszolgáltatások és a régiók esélyei az új területi munkamegosztásban – a hívóközpontok
Authors: Raffay Zoltán
Published: August 2018

A tanulmány egy egyre jelentősebb szolgáltatási ágazat, a hívóközpontok kialakulásának okait, az azt lehetővé tevő tényezőket és az ágazat eddigi fejlődését mutatja be, kitérve a hívóközpontok lehetséges jövőbeli fejlődési esélyeire is. A szerző azt is vizsgálja, hogy a hívóközpontok eddigi telephelyi döntéseik során a regionális kiegyenlítődés irányába hatnak-e, avagy az erősebb gazdasági alappal rendelkező régiókba települnek-e, a már meglévő fejlettségbeli különbségeket erősítve.
Kisalföldi és alföldi mezővárosok különbözősége, kisvárosi értékek védelme
Authors: Somfai Attila
Published: August 2018

Magyarországon sajátságos kontraszt figyelhető meg a két nagy országrészre (a Dunántúlra, ill. az Alföldre) jellemző történeti településfejlődésben. A történetileg kialakult falvak és mezővárosok településszerkezete a morfológiai felépítés szerint két fő csoportba sorolható: a Dunántúlra (és így az Észak-Dunántúlon található Kisalföldre is) jellemzők a soros felépítésű telepszerű települések, az Alföldön pedig megtalálhatók a kétbeltelkes felépítésű halmazos települések is, amelyek többsége közel kör alakú. A két fő csoporton belül számos altípus lehetséges. Egyes altípusok a későbbi korokban hozzáízesült településrészek miatt ma már nehezen ismerhetők fel, és a történeti településszerkezet nagymérvű megváltoztatására is akad példa.A történeti települések vizsgálata megmutatja, hogy az „indokolatlanul szabálytalannak” hitt történeti településalaprajz főbb elemeit számos esetben a topográfiai adottságok határozták meg, és részben ennek köszönhetik „egyszeri és megismételhetetlen” arculatukat. Ez a felismerés a településtervezőket a történeti településszövet jobb megbecsülésére ösztönözheti, és hozzájárulhat a gyakorlati településtervezés napjainkban tapasztalható szemléletváltozásához. A települések fejlesztésekor már nem csupán egyes műemléképületek, épületegyüttesek, utcák, terek védelme a cél, hanem az egész épített települési környezet és az őt befogadó táji környezet integrált védelme, az ún. jellegvédelem.
