Characteristics of Gelation by Amides Based on trans-1,2-Diaminocyclohexane: The Importance of Different Substituents
Authors: Nakagawa Haruka , Fujiki Mamoru , Sato Takaaki , Suzuki Masahiro , Hanabusa Kenji
Published: February 2017

Six diamides were prepared from trans-(1R,2R)-1,2-diaminocyclohexane and the corresponding racemate and were subsequently used as gelators. Three chiral compounds and their racemates were prepared. One of the chiral compounds and its racemate contained two n-dodecanoylamino groups as the same substituents. The other two chiral compounds and their racemates contained different substituents: 10-undecenoylamino and 2-heptyl-undecanoylamino groups, and 5-hydroxypentanoylamino and 2-heptylundecanoylamino groups. Their gelation abilities were evaluated on the basis of the minimum gel concentration using eight solvents. The thermal stability and transparency of the gels were investigated by UV–vis spectroscopy using three-component mixed solvents of hexadecyl 2-ethylhexanoate, liquid paraffin, and decamethyl cyclopentasiloxane (66 combinations). The gel-to-sol phase-transition temperatures were also studied. The viscoelastic behavior of the gels was studied by rheology measurements in the strain sweep mode. Aggregates constructing three-dimensional networks were studied by transmission electron microscopy and circular dichroism spectroscopy. The molecular packing of the gels was evaluated by small angle X-ray scattering (SAXS).

Non-small cell lung cancer: the new T1 categories
Authors: Van Schil Paul E.
Published: February 2017

Recently, major changes have occurred in the staging, diagnosis, and treatment of early stage lung cancer. By screening high-risk populations, we are now able to detect lung cancers at an early stage, but the false-positive rate is high. A new pathological classification was published in 2011 and fully incorporated in the 2015 World Health Organisation (WHO) Classification of Tumours of the Lung, Pleura, Thymus, and Heart. The new eighth edition of the tumour–node–metastasis (TNM) staging system has been fully published and will be in use from January 2017. T1 lesions are subdivided into T1a, T1b, and T1c lesions corresponding to lung cancers up to 10 mm, between 11 and 20 mm, and between 21 and 30 mm, respectively. To determine the size, only the solid part on computed tomographic scanning of the chest and the invasive part on pathological examination will be considered. Prognosis is significantly better for the smallest lesions. For some specific subgroups, sublobar resection may be oncologically valid and yield good long-term outcome, but the results of recently performed randomised trials are awaited.

Technical errors in ECG recording and treatment delays
Authors: Richley Dave , Winter Jason L
Published: February 2017

This case concerns a patient who was admitted to hospital as an emergency on the basis of presenting symptoms and abnormal features on his electrocardiogram (ECG). The ECG that was recorded on admission to hospital was misleading as a result of a technical error. The subsequent management of the patient, based at least partly on the interpretation of this ECG, might have had clinically adverse consequences. We discuss the mistake that was made in the recording of the ECG, its effect on the ECG appearances, and how the error could have been identified. This case illustrates the critical importance of both recording ECGs correctly and interpreting them accurately
Revalidation and the Code: duty of candour
Authors: Griffith Richard
Published: February 2017

A professional duty of candour is a key new standard of the revised Code from the Nursing and Midwifery Council (2015) . It requires cardiac nurses to be candid with patients about any errors in their care and treatment. Cardiac nurses working in England are also subject to a statutory duty of candour imposed on their employer by the Care Quality Commission. In this article, Richard Griffith considers the organisational and professional duties of candour and their impact on a cardiac nurse's practice.

Etelä-Suomen järvialueelta kerätystä 1817 lehtikuusitukin aineistosta tutkittiin tukkien latva- ja keskusmuotolukua, kapenemista ja latvakuoren paksuutta ja tehtiin vertailuja vastaavan alueen mänty- ja kuusitukkeihin. Lehtikuusitukeille laskettiin latvaläpimittaluokittaiset tilavuusluvut (m/m) kuorelliseen latvaläpimittaan perustuvaa kappaleittaista mittausta varten ja tarkasteltiin tukkieräkohtaisten mittaustulosten korjausmahdollisuuksia erän keskipituuden, keskilatvaläpimitan, tukkipuiden keskimääräisen rinnankorkeusläpimitan, tyvitukkien osuuden ja tyvitukkien ja muiden tukkien omien tilavuuslukujen avulla. Käytäntöön suositeltiin erän keskipituuteen perustuvia korjauskertoimia. Tällä menetelmällä virhe aineiston kokonaistilavuudessa oli +0,01 % ja eräkohtainen virhe oli –3 – +5 %. Tähän asti käytetyillä mänty- ja kuusitukkien mittausmenetelmillä virheet kokonaistilavuudessa olivat vastaavasti +1,3 ja –3,4 % ja eräkohtaiset virheet –11 – +7 % ja –16 – +4 %.3
Hakkuutähteen, karsijan puujätteen, sahan kuorijätteen ja kantojen murskaaminen Morbark 1200 -murskaimella
Authors: Pulkkinen Päivi , Asikainen Antti
Published: February 2017

Tutkimuksessa selvitettiin Morbark 1200 -murskaimen soveltuvuutta hakkuutähteen, karsijan puujätteen ja sahan kuorijätteen sekä kantojen murskaamiseen. Murskattava materiaali kuormataan Morbark 1200 -murskaimeen suppilomaisen syöttölaitteen kautta ylhäältä päin. Syöttäminen voidaan tehdä omalla kuormaimella tai erillisellä pyöräkuormaajalla. Parhaiten murskaimella pystyttiin käsittelemään ketjukarsija-kuorija-hakkurin jätettä ja sahan kuorijätettä. Päätehakkuualojen hakkuutähteiden murskauksessa tuottavuus oli selvästi alhaisempi. Tämä johtui pitkien latvakappaleiden aiheuttamista tukoksista syöttölaitteessa. Kantojen murskaukseen tutkittu murskain ei sovellu, sillä syöttölaite ei läpäise kunnolla kantoja. Kaikilla tutkituilla polttoaineilla saavutettiin hyväksyttävä palakokojaukauma. Kuitenkin jos murskaus tapahtui suoraan hiekkakentälle, murskeeseen sekoittui paljon hiekkaa, mikä alensi sen käyttökelpoisuutta polttoaineena.
Kasvupaikan ja puuston tiheyden vaikutus rauduskoivun ulkoiseen laatuun 30-vuotiaissa istutuskoivikoissa
Authors: Niemistö Pentti , Hukki Piia , Verkasalo Erkki
Published: February 2017

Samanikäisten rauduskoivujen pituus ei eronnut pelto- ja metsämailla, mutta läpimitta oli peltomailla keskimäärin 1 cm suurempi. Metsämailla istutuskoivut olivat lähes kaikilta laatuominaisuuksiltaan parempia kuin peltomailla. Vain alaoksien kuivumisessa ja karsiutumisessa ei ollut eroa. Peltokoivujen paksummat oksat ja voimakkaampi kapeneminen selittyivät vain osittain puiden nopeammalla paksuuskasvulla. Pintaviat ja mutkaisuus olivat yleisempiä peltomailla, mutta pystyoksia esiintyi vähän enemmän metsämailla. Tyvimutkia, lenkoutta ja halkeamia oli metsä- ja peltomailla yhtä paljon. Metsämaiden istutuskoivuissa oli vikoja yhtä paljon tai vähemmän kuin aikaisemmin tutkituissa luonnonkoivuissa. Nopeamman kasvun takia istutuskoivujen oksat olivat paksumpia, mutta tyviosan karsiutumisessa ei ollut suurta eroa.

Published: February 2017

Valtakunnan metsien viimeisimmät inventointitulokset osoittavat männyn ja kuusen kasvun alentuneen Suomen eteläosassa selvästi 1990-luvun alussa. Käsitystä kuusten vaikeuksista tukevat eri puolilla Etelä-Suomea löytyvät kuolleet yksilöt. Samantyyppinen ilmiö havaittiin 1930-luvun puolivälissä, jolloin Esko Kangas aloitti tutkimuksensa kuusen kuivumistyypeistä. Tämänkertaisen kuusen kuivumisen syyt ovat herättäneet vilkasta keskustelua sekä tutkija- että maallikkopiireissä. Kuivuus, routa, talviaikainen hengitys sekä otsoni ja erilaiset halogenoidut hiilivedyt johdannaisineen ovat yleisimpiä arvioita ilmiön syiksi.
Elinympäristövaatimuksiin perustuva arvio metsänhoidon vaikutuksista eri eliöryhmiin
Authors: Miettinen Pasi
Published: February 2017

Metsänhoidon jäljet näkyvät talousmetsien rakenteessa: nuoria ja keski-ikäisiä metsiä ja metsäkuvioiden reunavyöhykkeitä on paljon. Vanhat metsät ovat pienialaisia, ne sijaitsevat hajallaan ja vanhojen lehtipuiden osuus niissä on vähäinen. Metsäluonnossa tapahtuneet elinympäristömuutokset suosivat joitakin eliölajeja, toiset eliölajit puolestaan taantuvat muutosten vuoksi. Oheisessa katsauksessa esitetään arvio metsänhoidon eri toimenpiteistä hyötyvistä sekä niistä kärsivistä eliöryhmistä. Katsauksessa on käsitelty erikseen nisäkkäät, linnut, selkärangattomat, sienet ja kasvit. Laaditut taulukot perustuvat eri eliöryhmien asiantuntijoilta (yht. 17) saatuun arvioon.

Katsauksessa esitellään kirjallisuustarkastelun pohjalta tapaustutkimuksen metodiikkaa ja sen käyttöön liittyviä ominaispiirteitä. Tapaustutkimuksen perusteiden läpikäyntiin paneudutaan aloittaen sen määritelmästä ja ominaisuuksista intensiivisenä tutkimusstrategiana. Pohdittavana ovat mm. yhden ja useamman tapauksen tutkimisen erot ja yhtäläisyydet sekä tapaustutkimuksen suhde vertailevaan tutkimukseen. Tapaustutkimuksen toteutusvaiheet käydään läpi tutkimuksen suunnittelusta aineiston analyysiin. Tarkasteltaessa keinoja arvioida tapaustutkimuksen luotettavuutta ja tulosten yleistettävyyttä kiinnitetään erityinen huomio siihen, kuinka pitäydytään tapaustutkimukselle soveliaissa yleistyksissä. Tapaustutkimusstrategian esittelyn jälkeen tarkastellaan sen käyttöä suomalaisessa metsäntutkimuksessa. Vaikka tapaustutkimusta on käytetty myös metsätieteissä, sen perustaa on metsätieteellisissä tutkimuksissa harvoin selostettu. Johtopäätöksissä esitellään hyvän tapaustutkimuksen tunnuspiirteitä ja pohditaan sekä käytännöllisiä että tieteellisiä perusteluja strategian käytölle tietyissä tutkimustilanteissa.

Antecedents and consequences of transfer of training in public sector organizations
Authors: Bawono Icuk Rangga , Purnomo Ratno
Published: February 2017

Previous studies only focused on antecedent factors of transfer of training and only a few of them focused on the consequence factors. The main objectives of this research were to examine the antecedents and consequence of transfer of training. The antecedent factors consist of individual characteristics, training design, and organizational environment. The consequence factor is individual performance. Since the previous studies used transfer of training as unidimensional construct, this research used multidimensional construct consist of knowledge sharing, training retention and training generalization. Survey with questionnaire is used as design research method. The respondents are employee who worked in state-owned hospitals (N=202). Multiple regressions was used to examine the hypothesis. The result showed that individual performance was determined by training transfer consists of three factors such as knowledge sharing, training retention, and training generalization. Training of transfer itself was determined by some factors such as individual characteristics (i.e. self-efficacy and learning orientation), training design (trainer and training material), and organizational environment (organizational support, supervisor support and peer support). Specific for organizational support, it’s only had significant effect on training retention but not on knowledge sharing and training generalization. Since transfer of training has important effect on individual performance, organization must consider the three antecedent factors.
Publicness and strategic planning of public institutions: Evidence from Indonesia
Authors: Untoro Wisnu , Angriawan Arifin
Published: February 2017

Strategic planning has become a very common practice in public organizations. Research shows the positive impacts of strategic planning on the firm performance. This study examines the impacts of publicness on planning formalization, flexibility and participation. Empirical evidence collected from Indonesia suggests that planning formalization associates negatively with publicness; and mediates the relationships between publicness, flexibility and participation. The results support the political control view of public organizations. The results suggest that public organizations need to be both formal and flexible. We also find the positive association between participation and flexibility.

Published: February 2017

This study aims to measure the efficiency of profit and examine the factors that affect the efficiency of shariah banks profit in Indonesia such as the size of banks, risk financing, and capital adequacy. This study used the Shariah banks in Indonesia, during the period of 2010-2014. These shariah banks were selected as the sample Commercial shariah banks and Shariah Business Units. This study uses three stages of research. First, it measures the efficiency of profit using a parametric approach that is Stochastic Frontier Approach (SFA). Secondly, its uses regression profit efficiency scores with various determinants of profit efficiency. The third phase is testing the efficiency score during the global crisis (2008-2009) and after the global crisis period (2010-2014). It shows that in overall there occurred profit efficiency in the shariah banks in Indonesia as it was indicated by the score of profit efficiency that is less than one. The inefficiency occurred in both Shariah banks and shariah business units. Bank size has a positive impact on profit efficiency. The bigger the bank, the better profit efficiency is. It can be implied that this research provides the managers the clues that shariah banks should improve their profit efficiency management. For Bank Indonesia, they can use this evidence to design policies that can encourage profit efficiency in shariah banks.
Political Advertising in 2016: The Presidential Election as Outlier?
Authors: Franklin Fowler Erika , Ridout Travis N. , Franz Michael M.
Published: February 2017

The 2016 presidential campaign broke the mold when it comes to patterns of political advertising. Using data from the Wesleyan Media Project, we show the race featured far less advertising than the previous cycle, a huge imbalance in the number of ads across candidates and one candidate who almost ignored discussions of policy. This departure from past patterns, however, was not replicated at the congressional level. We draw some lessons about advertising from the 2016 campaign, suggesting that its seeming lack of effectiveness may owe to the unusual nature of the presidential campaign with one unconventional candidate and the other using an unconventional message strategy, among other non-advertising related factors.
Flow Behavior and Dynamic Recrystallization of BT25y Titanium Alloy During Hot Deformation
Authors: Yang Xuemei , Guo Hongzhen , Yao Zekun , Yuan Shichong
Published: February 2017

The high-temperature plastic deformation and dynamic recrystallization behavior of BT25y alloy were investigated within the deformation temperatures of 1,213–1,293 K and strain rates of 0.001–1.0 s–1 on a Gleeble-1500 thermo-mechanical simulator. Results showed that the dynamic recrystallization (DRX) mechanism played an important role in the hot deformation of BT25y alloy. Based on the regression analysis of the true stress–strain data, the stress exponent and deformation activation energy of BT25y alloy were calculated to be 3.4912 and 288.0435 kJ/mol, respectively. The θ-σ and dθ/dσ–σ curves were plotted to further obtain the critical stress and critical strain for the occurrence of DRX. Based on the analysis results, the DRX kinetic model was established. The model was validated by the comparison between predicted and experimental volume fraction of DRX. As the DRX evolution was sensitive to deformation temperature and strain rate, quantities of dynamically recrystallized grains appeared at higher temperatures and lower strain rates.
Off-Design Analysis of Transonic Bypass Fan Systems Using Streamline Curvature Through-Flow Method
Authors: Acarer Sercan , Özkol Ünver
Published: February 2017

The two-dimensional streamline curvature through-flow modeling of turbomachinery is still a key element for turbomachinery preliminary analysis. Basically, axisymmetric swirling flow field is solved numerically. The effects of blades are imposed as sources of swirl, work input/output and entropy generation. Although the topic is studied vastly in the literature for compressors and turbines, combined modeling of the transonic fan and the downstream splitter of turbofan engine configuration, to the authors’ best knowledge, is limited. In a prior study, the authors presented a new method for bypass fan modeling for inverse design calculations. Moreover, new set of practical empirical correlations are calibrated and validated. This paper is an extension of this study to rapid off-design analysis of transonic by-pass fan systems. The methodology is validated by two test cases: NASA 2-stage fan and GE-NASA bypass fan case. The proposed methodology is a simple extension for streamline curvature method and can be applied to existing compressor methodologies with minimum numerical effort.
Searching for Nitrogen-Fixing Microorganisms: An Original, Relevant, and Successful Early Research Experience
Authors: Costas Amaya Garcia , Ragen Devon L. , Peters John W.
Published: February 2017

A five-week research project was designed as part of a summer internship for high school students, and could also be used with educators or in introductory undergraduate research courses. This is a guided-inquiry-based project, framed within the significant issue of supplementing fertilizer use in agriculture with nitrogen-fixing microorganisms. This experience exposes students to how scientists are studying real-world problems; it teaches them basic research techniques, and promotes inquiry-based learning in a real research environment. It also fills a current gap in K-12 education that lacks enough microbiology emphasis. Research interns collect soil samples from various fields and use culture-dependent and culture-independent techniques to test whether there are nitrogen-fixing microorganisms that can be isolated and identified in each soil sample. Students work in a research laboratory making nitrogen-free media; culturing, isolating, and identifying microorganisms; extracting soil DNA; and amplifying the 16S rRNA and nifH genes. We administer a pre-test and a post-test, and students present their research both in a short talk and with a poster. By hosting high school students in a research laboratory and immersing them in laboratory science, we hope to inspire them to pursue a STEM-related career.

Published: February 2017

En la administración de Guadalupe Victoria, los imparciales surgieron con la intención de replantear significativas problemáticas de la gobernabilidad establecida con la república federal en 1824, especialmente las logias. La suya fue una voz protagónica para las inquietudes de diferentes sectores, ya fueran contrarios a sociedades escocesas y yorkinas o estuvieran insertos en ambas. Esta investigación analiza ideas y prácticas de los imparciales desde la publicación periódica Águila Mejicana, hasta los principales debates de ésta con periódicos masónicos líderes. También explica de qué manera los imparciales contribuyeron a eliminar ambas logias y, al mismo tiempo, ofrecieron nuevos y substanciales fundamentos para cohesionar a los “hombres de bien”.

During the Guadalupe Victoria administration, the “Impartials” criticized key governance issues established in the 1824 first federal republic, especially when related to the Masonic Lodges. They voiced the concerns of many key sectors that opposed the Masonic Lodges. This article analyzes Impartials’ ideas and practices in the Águila Mejicana publication. Likewise, it examines the debates between the Impartials and the Masonic Lodges periodicals in Mexico City. This article explains how the Impartials contrived to eliminate the Masonic Lodges. Furthermore, it explores the new foundations the Impartials established to bring together the so-called “hombres de bien.”
Attenuation of epidermal growth factor (EGF) signaling by growth hormone (GH)

Published: February 2017

Transgenic mice overexpressing growth hormone (GH) show increased hepatic protein content of the epidermal growth factor receptor (EGFR), which is broadly associated with cell proliferation and oncogenesis. However, chronically elevated levels of GH result in desensitization of STAT-mediated EGF signal and similar response of ERK1/2 and AKT signaling to EGF compared to normal mice. To ascertain the mechanisms involved in GH attenuation of EGF signaling and the consequences on cell cycle promotion, phosphorylation of signaling mediators was studied at different time points after EGF stimulation, and induction of proteins involved in cell cycle progression was assessed in normal and GH-overexpressing transgenic mice. Results from kinetic studies confirmed the absence of STAT3 and 5 activation and comparable levels of ERK1/2 phosphorylation upon EGF stimulation, which was associated with diminished or similar induction of c-MYC, c-FOS, c-JUN, CYCLIN D1 and CYCLIN E in transgenic compared to normal mice. Accordingly, kinetics of EGF-induced c-SRC and EGFR phosphorylation at activating residues demonstrated that activation of these proteins was lower in the transgenic mice with respect to normal animals. In turn, EGFR phosphorylation at serine 1046/1047, which is implicated in the negative regulation of the receptor, was increased in the liver of GH-overexpressing transgenic mice both in basal conditions and upon EGF stimulus. Increased basal phosphorylation and activation of the p38-mitogen-activated protein kinase might account for increased Ser 1046/1047 EGFR. Hyperphosphorylation of EGFR at serine residues would represent a compensatory mechanism triggered by chronically elevated levels of GH to mitigate the proliferative response induced by EGF.

Los cuentos de esta colección apuntan las causas políticas, económicas y culturales del racismo contra negros, chinos e indígenas. Se explicitan los procedimientos discursivos en los que se materializa el racismo, y se señalan las implicaciones sociales e ideológicas derivadas del abordaje de la problemática de los negros. Se ejemplifica la poética de Pacheco con un análisis de cuatro relatos: «Juan Chac», «Fichas», «Vocación» y «Congolí».The ethno-cultural poetics of Más abajo de la piel, by Abel Pacheco, is analyzed in order to emphasize the shift from a “negrista” view toward that of negritude. The stories in this collection point to political, economic and cultural causes of racism against blacks, Chinese and indigenous. Discourse procedures are made explicit where racism materializes, and the social and ideological implications derived from this exploration of the issue regarding blacks are discussed. Pacheco’s poetics is exemplified by a brief analysis of four stories: “Juan Chac,” “Fichas,” “Vocación” and “Congolí.”
Nacionalismo conflictivo: exclusión-asimilación en Trocitos de carbón, de Carlos Gagini (Troubled Nationalism: Exclusion-Assimilation in Trocitos de carbón, by Carlos Gagini)
Authors: Solano Rivera Silvia
Published: February 2017

Se analiza Trocitos de carbón (1923), de Carlos Gagini, una de las primeras muestras de un nacionalismo inclusivo que tiene en cuenta las provincias periféricas de Guanacaste, Puntarenas y Limón. Al mismo tiempo, el texto materializa los remanentes de un racismo excluidor y excluyente de los elementos hasta ese momento considerados extranjeros o inmigrantes como son los negros limonenses, los cuales son aceptados únicamente si se asimilan al centro cultural hegemónico vallecentrista.Trocitos de carbón (1923), by Carlos Gagini, is analyzed as one of the first cases of an inclusive nationalism that takes into account the provinces of Guanacaste, Puntarenas and Limón. At the same time, the text materializes the remnants of a discriminatory racism of those elements considered then as foreigners or immigrants, such as black people from Limón, accepted only if they assimilate the hegemonic culture of the central valley.

The growing interest in nanostructured conducting polymers is caused by expanding area of their practical application. Conducting polymers can be used in new electronic devices (transistors, displays, sensors, energy storage and memory cells), materials for shielding electromagnetic irradiation, inhibition of corrosion, membrane constructing, catalysis and medicine. The studies of polyaniline (PANI) and other conducting polymers have shown that they possess semiconducting properties. Due to its high stability and unique complex of properties, PANI was the first among conducting polymers to be used in practice as an electrode material for batteries, as a corrosion inhibitor and detecting material for sensors. PANI without dopant material possesses controlled conductivity 10-10 S∙cm-1. PANI was synthesized by the interfacial method by oxidation of aniline with ammonium peroxydisulfate (APS) as an oxidant in an immiscible organic/aqueous biphasic system, with hydrochloric acid as dopant. An organic phase contained aniline dissolved in toluene, while the oxidant was dissolved in acid. The produced PANIs have conductivities in the range 0.03-0.07 S.cm−1. Their nanofiber morphology was confirmed by scanning electron microscopy (SEM). Molecular structure of synthesized PANIs was investigated by FTIR Spectroscopy.

Published: February 2017

High concentration of phosphates in the water can lead to eutrophication which leads to uncontrolled growth of algae (algae blooming). It underlies the need for determining the concentration of phosphate in the aquatic environment. However, the concentration of phosphate may change during storage of samples so that an accurate analysis difficult to achieve unless carried out in-situ. DGT (Diffusive Gradient in Thin Films) is an in-situ measurement method developed for measuring phosphate and metal. In this study the use of Fe-Al-Oxide as a binding gel that is expected to bind phosphate with a capacity greater than ferrihydrite. N, N'-methylenebisacrylamide is used as a substitute for commercial DGT Crosslinker as crosslinking for a cheaper price and selective for small molecule. Ferrihydrite-DGT and Fe-Al-Oxide-DGT are tested with a variety of concentrations, pH, and contact time. In both methods DGT found that the pH for phosphate measurements performed at pH 3. Capacity of Fe-Al-Oxide binding gel known to be higher than the ferrihydrite binding gel with result Cferrihydrite-DGT:Cstart is 76% and CFe-Al-Oxide-DGT:Cstart is 82%.DOI :http://dx.doi.org/10.15408/jkv.v0i0.3597

The psychological imagination
Authors: Tateo Luca
Published: February 2017

Abstract: The commentary presents an epistemological reflection about Dialogical Self theory. First, the theoretical issues of DS about the relationship between individuality, alterity and society are discussed, elaborating on the articles of this special issue. Then, it is presented the argument of psychologist's ontological fallacy, that is the attitude to moving from the study of processes to the study of psychological entities. Finally a development toward new research directions is proposed, focusing on the study of higher psychological functions and processes, taking into account complex symbolic products of human activity and developing psychological imagination.

Authors: Kelly Brian L.
Published: February 2017

This study explores a music studio in a transitional living program for young people experiencing homelessness. Using an ethnographic approach, data were collected to explore: (a) young people's experiences in the music studio, (b) the meanings they attach to their experiences, and (c) whether involvement in the studio engages their strengths. Study findings present a compelling narrative that supports the use of music-based services for young people experiencing homelessness as a way to engage their strengths and foster important opportunities for connection, engagement, and creative expression. Findings highlight the importance of challenging prescriptive notions of homeless youth and developing services that engage their strengths.
Crossrail project: machine-driven tunnels on the Elizabeth line, London
Authors: King Mike , Thomas Ivor , Stenning Andy
Published: February 2017

The 42 km of tunnels constructed using soft-ground pressure-balance tunnel-boring machines for London’s new Elizabeth line were completed over a 3 year period. A single lining design solution was developed for all tunnels using a fully gasketed, steel-fibre-reinforced, concrete segmental lining suitable for use in all potential ground conditions anticipated along the alignment. The £14·8 billion Crossrail project faced many challenges, including dealing with significant quantities of different excavated material while minimising the environmental impact from transportation and disposal, minimising settlement effects and dealing with multiple tunnel-boring machine launches and receptions. This paper addresses how the issues were tackled and comments on the tunnel-boring machine design and the approach taken for survey control. Outline figures are also provided for the tunnelling rates. Finally, some conclusions and recommendations are made based on the observations and lessons learnt during the project.
O impacto da universidade pública no desenvolvimento regional sob a luz da literatura internacional / The Impact of the public university in regional development from the perspective of international literature
Authors: Hoff Débora Nayar , Pereira Camila Amaral , De Paula Luis Gustavo Nascimento
Published: February 2017

Resumo

O objetivo deste artigo é rever, a partir de seu confronto com a discussão internacional sobre o assunto, o modelo analítico proposto por Hoff, San Martin e Sopeña (2011) para a análise do impacto das universidades públicas no desenvolvimento regional. O modelo, originalmente, foi desenvolvido a partir de referências nacionais para o tema. Para tanto, utiliza-se a técnica de pesquisa bibliográfica e documental. O referencial teórico estudado demonstra que o modelo analítico estabelecido com referências nacionais mostra-se correspondente à discussão apresentada pela literatura internacional sobre o tema. Destaca-se, no entanto, que a literatura internacional apresenta enfoque direcionado às relações com o ambiente externo à universidade, principalmente com o meio empresarial, fato não tão presente na literatura nacional. Conclui-se que a literatura internacional ratifica o modelo proposto por Hoff, San Martin e Sopeña (2011).

Abstract

The purpose of this article is to review, from its confrontation with the international discussion, the analytical model proposed by Hoff, San Martin and Sopeña (2011) to analyze the impact of public universities in regional development. The model originally was developed from national reference to the subject. Therefore using the bibliographic and documentary research technique. The studied theoretical framework shows that the analytical model established with national references is shown corresponding to the discussion presented in the international literature on the subject. Noteworthy, however, that the present international literature focusing mainly on relations with the external environment to the university, especially with the business community, which was not so present in the national literature. We conclude that the international literature confirms the model proposed by Hoff, San Martin and Sopeña (2011).
A Cidade Inteligente: uma reterritorialização / Smart City: A reterritorialization
Authors: Cury Mauro José Ferreira , Marques Josiel Alan Leite Fernandes
Published: February 2017

Resumo

As cidades inteligentes são formas de apropriação do espaço urbano baseadas na utilização de três inteligências – a humana, a coletiva e a artificial – e que implica em transformações territoriais. A pesquisa objetiva discutir a cidade inteligente como uma reterritorialização do espaço das cidades, pelo exame conceitual de território, territorialidade, desterritorialização e reterritorialização. A justificativa está calcada na busca contemporânea por soluções aos problemas sociais, econômicos e culturais que as cidades enfrentam. A problemática nos induz a responder se as cidades inteligentes, ao criarem soluções, redefinem as formas e funções do espaço e por si constituem uma reterritorialização. A metodologia empregou a pesquisa documental e empírica, com revisão conceitual de autores meritórios nos temas como Komninos (2008), Haesbaert (2004), Raffestin (1993) e Sack (1986). A pesquisa apresenta as respostas à problemática de que o processo de desenvolvimento urbano propagado pelas cidades inteligentes é capaz de redefinir o uso e as ocupações dos espaços locais, regionais e nacionais, ensejando transformação territorial e, dessarte, uma reterritorialização.

Abstract

Smart cities are forms of appropriation of urban space based on the use of three intelligences – human, collective and artificial – and that implies territorial transformations. The research aims to discuss the smart city as a reterritorialization of all urban space through the conceptual examination of territory, territoriality, deterritorialization and reterritorialization. The justification is grounded in the contemporary search for solutions to social, economic and cultural problems facing cities. The problem leads us to respond if smart cities by creating solutions redefine the forms and space functions and by itself is a reterritorialization. The methodology employed documentary and empirical research with conceptual review of meritorious authors on topics such as Komninos (2008), Haesbaert (2004), Raffestin (1993) and Sack (1986). The research presents the answers to the problems of the urban development process propagated by the smart cities are able to redefine the use and occupation of the local, regional and national spaces, allowing for territorial transformation, and thus faces a reterritorialization.
