Simultaneous Determination of Linalool, Ambrox, and Sclareolide in Clary Sage Oil by GC-MS
Authors: Xu Yang-Bin , Wang Kai , Zhu Rui-Zhi , Zhe Wei , Li Zhi-Yu
Published: December 2014

The volatile components of clary sage oil were identified by gas chromatography/time-of-flight mass spectrometry (GC-TOFMS). The peak area normalization method was used to calculate the relative content of the components. With the MS library search, 32 compounds, which account for 91.24% in the volatile components of clary sage oil, were confirmed by using retention index. A rapid and effective GC-MS method for simultaneous determination of linalool, ambrox, and sclareolide in clary sage oil has been developed. Three samples were used for method evaluation. The relative standard deviations (RSD) were <4% for linalool, ambrox, and sclareolide. The limits of detections (LOD) were 80, 50, and 150 µg L−1 for linalool, ambrox, and sclareolide, respectively. The recoveries were 90–109% for linalool, 91–105% for ambrox, and 94–103% for sclareolide. The method could be applied to measure linalool, ambrox, and sclareolide in clary sage oil.
Photocatalytic Water Splitting over Rod-shaped K3Ta3Si2O13 and Block-shaped Ba3Ta6Si4O26 Prepared by Flux Method
Authors: Takayama Tomoaki , Iwase Akihide , Kudo Akihiko
Published: December 2014

K3Ta3Si2O13 and Ba3Ta6Si4O26 particles prepared by a flux method using KCl possessed well-crystallized nanorod and block shapes, respectively. The K3Ta3Si2O13 and Ba3Ta6Si4O26 with one-dimensional and linear pillared structure showed photocatalytic activities for water splitting. The quantum yields were 2.4% and 0.2% at 254 nm for NiO/K3Ta3Si2O13 and NiO/Ba3Ta6Si4O26, respectively. The difference in the photocatalytic activity was related to the degree of distortion of the one-dimensional pillared structure.

A new probe specific for singlet oxygen (1O2) was designed by incorporating the reactive anthracene moiety into a rhodamine fluorophore. The new probe displayed selective and sensitive response to 1O2, and it was further applied in a biological system to trace the endogenous 1O2 in Hela cells.
Experimental Study of Transmission Characteristics of a Disk Drive's Vibration Characteristics of a Disk Drive's Vibration
Authors: Chiu Min-Chie , Chang Ying-Chun
Published: December 2014

Presently, there is a trend to design larger capacity hard disks that have a faster revolving speed and a precise mechanism. However, because of external vibrations, these are highly sensitive to data transmission. Therefore, vibration control on hard disks is crucially important.

In this paper, a traditional hard disk is placed on a vibration testing device. Data transmission efficiency for the disk will be detected via IOmeter software. Here, the influence of a traditional hard disk's data transmission with respect to external forces (various vibration accelerations), revolving speeds, tilted angles, hardness and thickness of damping material, and material property will be experimentally assessed. Results reveal that a slight tilted angle will result in better data transmission. In addition, the hardness of the hard disk plays an essential role in reducing the vibrational impact on the data transmission. Also, data transmission in the damping material of the shoe cushion will be more efficient than that of a pneumatic cushion. Moreover, the data transmission will decrease when the rotating speed of the disk increases.

Consequently, the thickness of the damping material will influence the data transmission even though the hardness is fixed.
Frequency-Domain Substructure Isolation for Local Damage Identification
Authors: Hou Jilin , Jankowski Łukasz , Ou Jinping
Published: December 2014

This paper proposes a frequency-domain method of substructure identification for local health monitoring using substructure isolation method (SIM). The first key step of SIM is the numerical construction of the isolated substructure, which is a virtual and independent structure that has the same physical parameters as the real substructure. Damage identification and local monitoring can be then performed using the responses of the simple isolated substructure and any of the classical methods aimed originally at global structural analysis. This paper extends the SIM to frequency domain, which allows the computational efficiency of the method to be significantly increased in comparison to time domain. The mass-spring numerical model is used to introduce the method. Two aluminum beams with the same substructure are then used in experimental verification. In both cases the method performs efficiently and accurately.
A Time-Varying Model for Predicting the Life-Cycle Flexural Capacity of Reinforced Concrete Beams
Authors: Zhong X.P. , Jin W.L. , Xia J.
Published: December 2014

Based on previous studies and Faraday's Law, time-varying models of the uniform corrosion of reinforcing bars, both before and after the onset of cracking of the reinforced concrete (RC) cover have been established by analyzing the processes and time-varying mechanisms of reinforcement corrosion caused by chloride ions. The influence of time-varying bond strength performance on the flexural capacity of RC structures is reflected by a time-varying corrosion effect coefficient. The relationship between this coefficient and corrosion depth and time is also given in this paper. A time-varying model for the flexural capacity of RC beams in a chloride environment over a whole life cycle was then produced based on the time-varying reinforcing steel material performance, the time-varying bond performance, and standard structural member design theory. Lastly, the model was verified by comparing experimental and model based calculated data. The model was shown to be fit for practical engineering application in predicting flexural capacity and consequently has the impact on structural safety for any future year during the structure's service life.
Dynamic Analysis of a Cracked Beam-Like Bridge Subjected to Earthquake and Moving Vehicle
Authors: Nguyen Khoa Viet
Published: December 2014

This paper presents the influence of a crack on the dynamic behavior of a beam-type bridge subjected to separately or simultaneously a moving vehicle and earthquake excitation. In this study, the bridge is modelled as a 3D beam by the finite element method. The stiffness matrix of a cracked beam element with rectangular section adopted from fracture mechanics is presented. The influences of crack appearance time, crack location, crack depth, and vehicle speed on the dynamic response of the bridge are investigated. When a crack is induced during external excitation the stiffness of the structure is changed leading to a change in natural frequencies during vibration. This change in the frequency is analysed by wavelet spectrum, a time-frequency analysis which can examine locally a signal in both time and frequency domains. The relationship between the crack depth and the instantaneous frequency (IF) of the structure is established which may prove useful for assessment of the crack depth. Numerical simulation results are presented to investigate the efficiency of the method.
In-Situ Validation of a Wireless Data Acquisition System by Monitoring a Pedestrian Bridge
Authors: Chen Zhi-Cong , Casciati Sara , Faravelli Lucia
Published: December 2014

When compared to wired sensor technology, wireless sensor technology often suffers long data collection delay, big noise floor and data loss. Addressing these challenges, a wireless data acquisition system was designed and implemented by the authors. It can provide a performance comparable to the one of a wired data acquisition system. In this paper, the system is validated by its application in the monitoring of a timber pedestrian bridge in Italy. The system features flexible sensor interfaces, high power efficiency, low noise data acquisition, real-time and lossless wireless data transmission, and a convenient graphical user interface. Two field experiments were conducted. In the first experiment, the wireless data acquisition unit was designed to use an unreliable communication mode, resulting in an underestimated data loss problem. In the second experiment, the system is improved. The ACK-RETRIES reliable communication mode and a data packet sequence number checking mechanism are adopted, so that the data loss was avoided. For a comparison, a wired portable data acquisition system VSS-3000 was also used to acquire data from one accelerometer. The results show that the wireless data acquisition system is able to acquire high quality data from low noise sensors in real time without data loss. Compared to the VSS-3000, the data acquired by the wireless sensor platform have a comparable and even better quality.
Interpreting Metadata and Ontologies of Virtual Heritage Artefacts
Authors: Pauwels Pieter , Di Mascio Danilo
Published: December 2014

Many cultural heritage artefacts are digitised, resulting in a considerable number of virtual heritage artefacts, including 3D models, textual database records, images, point clouds, videos and so forth. These virtual heritage artefacts are often, if not always, accompanied by metadata standards and commonly agreed upon ontologies. These metadata and ontologies allow to build representations of virtual heritage artefacts that can be shared afterwards across different environments. In other words, the information about the artefact is interoperable. In many cases, however, it appears to be not so straightforward to use the artefact information in a context different from what it was initially meant for. This situation is analysed here, indicating that the interpretation of artefacts, both virtual and real, depends not only on the observed entities (virtual and real artefacts), but also on the background knowledge of the interpreter (personal), which can only remotely be captured in metadata and ontologies (cfr. user profiles). From the analysis results, recommendations are proposed about the pragmatic usage of metadata and ontologies in the context of virtual heritage artefacts.
X3D Fragment Identifiers — Extending the Open Annotation Model to Support Semantic Annotation of 3D Cultural Heritage Objects over the Web
Authors: Yu David , Hunter Jane
Published: December 2014

This paper describes extensions made to the Open Annotation (OA) data model to enable the semantic annotation of points, surface regions and volumetric segments on 3D cultural heritage artefacts. More specifically it describes how the X3D (Extensible 3D Graphics) standard has been adapted to support concise, machine-processable and persistent 3D fragment identifiers. Methods to improve the efficiency of capturing, compressing and processing the X3D fragment identifiers are also described. The proposed X3D extensions are implemented and evaluated using a test-bed of 3D representations of ancient Greek Vases. The advanced annotation and search services that are achievable as a result of combining OA and X3D for the underlying annotation data model are also described. The benefits of this approach are demonstrated by measuring the improvements in file size and response times that are achieved. We also present evaluation results that indicate that the X3D approach combined with innovative run-length encoding (RLE) and innovative processing methods, improves the speed and efficiency of searching, retrieving and rendering annotations on 3D digital objects, over the Web.
The PDB database is a rich source of alpha-helical anti-microbial peptides to combat disease causing pathogens
Authors: Chakraborty Sandeep , Phu My , Rao Basuthkar J. , Asgeirsson Bjarni , Dandekar Abhaya M.
Published: December 2014

The therapeutic potential ofα-helical anti-microbial peptides (AH-AMP) to combat pathogens is fast gaining prominence. Based on recently published open access software for characterizingα-helical peptides (PAGAL), we elucidate a search methodology (SCALPEL) that leverages the massive structural data pre-existing in the PDB database to obtain AH-AMPs belonging to the host proteome. We providein vitrovalidation of SCALPEL on plant pathogens (Xylella fastidiosa,Xanthomonas arboricolaandLiberibacter crescens) by identifying AH-AMPs that mirror the function and properties of cecropin B, a well-studied AH-AMP. The identified peptides include a linear AH-AMP present within the existing structure of phosphoenolpyruvate carboxylase (PPC20), and an AH-AMP mimicing the properties of the twoα-helices of cecropin B from chitinase (CHITI25). The minimum inhibitory concentration of these peptides are comparable to that of cecropin B, while anionic peptides used as control failed to show any inhibitory effect on these pathogens. Substitute therapies in place of conventional chemotherapies using membrane permeabilizing peptides like these might also prove effective to target cancer cells. The use of native structures from the same organism largely ensures that administration of such peptides will be better tolerated and not elicit an adverse immune response. We suggest a similar approach to target Ebola epitopes, enumerated using PAGAL recently, by selecting suitable peptides from the human proteome, especially in wake of recent reports of cationic amphiphiles inhibiting virus entry and infection.
The ontogeny of the embryonic, foetal and infant human umwelt
Authors: Tønnessen Morten
Published: December 2014

This article, which envelops a case study and development of umwelt theory, addresses four research questions: At what point does the human umwelt emerge? What umwelt transitions can be identified in the ontogenesis of the early human umwelt? What is characteristic of the umwelt trajectory of human embryos/ foetuses/infants? How are umwelt objects established/crystallized/fixated in the human umwelt?The early human umwelt is characterized by rapid change, radical transformations, and gradual establishment of the first and most basic umwelt objects by way of exploration and learning. While the human umwelt arguably emerges already at the embryonic stage, the sense-saturated umwelt emerges at the foetal stage. Unlike an adult human’s umwelt, but like other altricial umwelten, the umwelt of the human foetus and infant is not fully functional from the perspective of the organism itself. In other words, their basic functioning directly depends on others. Our human sociality is further stimulated by shared undertakings early on in our terrestrial lives which effectively make us part of some specific social system.
Graphic design production as a sign
Authors: Restrepo Boada María del Rosario
Published: December 2014

The article attempts to show that graphic design production works through a particular semiotic process. The performance of a new sign category, the Graphic Sign, makes possible the articulation of the iconic, the plastic, and the linguistic signs in case of a specific dialogue that exists between the letters and the images in some graphic design productions. Overhauling theories of Eco, Groupe μ and Klinkenberg, we will be able to understand that Graphic Design generates meaning in a formal dimension, yet it also generates particular cognitive structures. Therefore, understanding this new kind of sign, we can recognize its communicational dimension and the powerful cultural creation platform this Design is, beyond its ability to make things visible and in the best cases clear and beautiful.
On the embedded cognition of non-verbal narratives
Authors: Bruni Luis Emilio , Baceviciute Sarune
Published: December 2014

Acknowledging that narratives are an important resource in human communication and cognition, the focus of this article is on the cognitive aspects of involvement with visual and auditory non-verbal narratives, particularly in relation to the newest immersive media and digital interactive representational technologies. We consider three relevant trends in narrative studies that have emerged in the 60 years of cognitive and digital revolution. The issue at hand could have implications for developmental psychology, pedagogics, cognitive science, cognitive psychology, ethology and evolutionary studies of language. In particular, it is of great importance for narratology in relation to interactive media and new representational technologies. Therefore we outline a research agenda for a bio-cognitive semiotic interdisciplinary investigation into how people understand, react to, and interact with narratives that are communicated through non-verbal modalities.

Evaluation of a skin barrier cream for managing IAD in elderly patients using high-frequency ultrasound
Authors: Kerr Andy , Arrowsmith Martin , Young Steve , Jaimes Henry
Published: December 2014

Incontinence-associated dermatitis (IAD) is a defined pathological entity and presents a significant burden for patients and health-care systems. The main objective of this evaluation was to test the efficacy and safety of a skin barrier cream in the management of uncomplicated IAD in elderly patients. Ten incontinent patients with mobility problems that presented with signs of IAD were included in the evaluation. The evaluation took place during a 2-week period. The product's efficacy was objectively evaluated in each patient with high-frequency ultrasound scans taken from the irritated skin compared with an ultrasound scan taken from normal adjacent (control) skin. Data analysis showed a statistical significance in favour of the capacity of the product to help reduce inflammatory signs. Photographic follow-up allowed correlation of ultrasound findings and clinical signs. The product was effective in treating the skin irritation and preventing further skin breakdown. There were no adverse events during the evaluation.
The unique contribution of community clinical nurse specialists in rural Wales
Authors: Roberts Debbie , Hibberd Pat , Lewis Christopher Alan , Turley Joanne
Published: December 2014

To date, quality indicators that have been developed for nursing tend to focus on acute, secondary care settings. It remains unclear whether such quality indicators are applicable to community settings, particularly in rural environments. This research aims to identify the consensus view among specialist nurses regarding their unique nursing contribution within their rural community. Identifying agreed aspects of the unique role within the rural community area will enable quality care metrics to be developed, allowing specialist nurses to measure their unique contribution to rural health care in the future. The research used the Delphi technique to identify a consensus view among a population of specialist community nurses working in a designated rural area in Wales. The strongest area of consensus related to clinical and teaching expertise, where participants perceive educational expertise as being at the forefront of their role. In terms of care for individuals, consensus was focused on four main areas: developing appropriate criteria for referral in to the service, collaborative working, education, and advocacy roles. The findings highlight similarities to models of care provision elsewhere. Specific quality indicators are required for clinical nurse specialists working in rural areas. Current quality indicators may not be applicable across all clinical settings. Further work is required to explore the nature of rural nursing practice.
Meeting targets in pressure ulcer prevention in the community by collaborating with industry
Authors: Woodhouse Lucy , Graham Katriona
Published: December 2014

This article describes how a community health-care trust achieved a reduction in acquired pressure ulcers. Commissioning for Quality and Innovation 2014/15 guidance states that provider organisations should work with their partners across their local health and social care system to address the causes of pressure ulcers and reduce their prevalence, regardless of source. Gloucestershire Care Service NHS Trust was challenged to reduce the number of acquired pressure ulcers by 17% in 2013–14. The challenge for the three members of the tissue viability team was to train the qualified and unqualified staff within seven community hospitals and district nurse teams from 85 GP practices, covering a population of 600 000 within 4 months. Staff shortages and a lack of venues available meant that an adaptive educational approach was necessary. A dedicated programme of educational support from both the tissue viability nurse and an industry partner enabled the delivery of a wide range of educational materials to staff across the county. As a result of this partnership working, there was a reduction of category 3 and 4 pressure ulcers, and an increased awareness of the initial stages of pressure ulcer development demonstrated by an increase in grade 2 pressure ulcers.
Prevention and management of incontinence-associated dermatitis using a barrier cream
Authors: Holroyd Sharon , Graham Katriona
Published: December 2014

Incontinence-associated dermatitis (IAD) is a common skin disorder affecting patients with urinary and/or faecal incontinence. Maintaining the skin's integrity is a challenge, particularly in the elderly and individuals with medical or surgical comorbidities. It is widely reported that the issue is complex and recognition is inconsistent, with symptoms often being confused with those of pressure ulcers. This article explores the causes of IAD, looking at the structure of healthy skin and the pathology that occurs during skin breakdown. It identifies risk factors and prevention and management strategies, including the use of barrier creams. The article then presents the results of a large product evaluation that took place with Cavilon Durable Barrier Cream (3M). The barrier cream was shown to be more effective in treating and managing patients with IAD than the previous product that patients had been using. A case study is also included to demonstrate the efficacy of the newest version of Cavilon Durable Barrier Cream.
Maggot debridement therapy: a systematic review
Authors: Shi Eric , Shofler David
Published: December 2014

Maggot debridement therapy is used extensively in the UK in both community and hospital situations, but remains a potentially under-used modality in many wound care markets. It promotes wound healing by performing three key processes: debridement, disinfection and growth-promoting activity. It can be used for the debridement of non-healing necrotic skin and soft tissue wounds, including pressure ulcers, venous stasis ulcers, neuropathic foot ulcers and non-healing traumatic of post-surgical wounds. With the increase in chronic diabetic foot wounds, maggot debridement therapy is a promising tool for health professionals dealing with difficult wounds. This article presents an overview of the research evidence surrounding maggot debridement therapy that serves as a guide to health professionals who may be users of this form of treatment now and in the future.

All midwifery preparation courses in Wales are provided at diploma level, with successful students being awarded a joint Welsh National Board (WNB)AJniversity of Wales Higher Education Diploma in Midwifery.
Do men need midwives: facilitating a greater involvement in parenting
Authors: Lester Annie , Moorsom Sophie
Published: December 2014

Very little attention is paid in midwifery to the needs of the expectant father. Most often, when he is taken into account it is not his needs that are addressed but rather ways in which he can provide his partner with support. Mother, father and baby form a three-sided unit and the exclusion of any member of the family can be detrimental to the health of all (Bedford and Johnson, 1988). Midwives will have a positive impact on the wellbeing of all the family members if they extend their practice to address the needs of men during their transition to fatherhood. Such an approach to care would facilitate the greater involvement of men in parenting.

American hýbris: US Democracy Promotion in Cuba after the Cold War — Part 1
Authors: Alessandro Badella
Published: December 2014

Cuba is probably one of the best examples of the significance of the democracy promotion discourse in US foreign policy: the efforts to democratise the island have been one of the main features in the US—Cuba bilateral relations since the end of the Cold War. Even the embargo against the island has evolved from a tool to generate regime change to an instrument of democracy promotion to foster a democratic transition. Today, the Cuban embargo, after the codifications of the 1990s, is intimately connected to a ‘Cuban democratic future’. Moreover, in the last three decades, US presidents have committed themselves to promote democracy on the island, inaugurating a sort of ‘state policy’ with little or no evolutions or changes. The main aim of this two-part article is to explore the rationale behind US decennial efforts to promote a peaceful democratic change on the island, while trying to answer some crucial questions about US strategy in Cuba: Why promote democracy in Cuba? Why did democracy promotion become a long-lasting feature in US—Cuba relations? The first part deals with the security framework, and American economic interests in Cuba as a crucial push factor for democracy promotion, while the role of the Cuban-American community and the problems and perspectives of US strategy will be included in the second part, to be published in the next issue of the Journal.
Cuban Education between Revolution and Reform
Authors: Danay Quintana Nedelcu
Published: December 2014

In recent years, Cuba has been immersed in a process of profound change. Among
these changes, one that has been less addressed by specialists both inside and
outside the island is ‘education reform’, specifically at the
university level. The relevance of this study is to understand the current
university education policy as the one that has perhaps the most political
content, the analysis of which would help to understand the challenges in
political and ideological matters faced by the government of Cuba today.
Therefore, the present work makes a critical assessment of the Cuban educational
model based on values as a central focus of university policy and its relevance
in the transcendental process of change happening in Cuba today. For students of
public policy, the Cuban case encapsulates an important singularity that allows
the possibility of analysing short-term versus long-term assessments of public
problems (Ascher 2009). It also allows us to learn about social and policy
challenges in a country that has achieved universal mass, free and quality
education that has been able to extend itself beyond the capital
(Mészarós 2008). What happens next? A reflection on the role of
education in a changing society is one of the main purposes of this work.
Medienrhetorik des Fernsehens

Wodurch überzeugt das Fernsehen? Was ist sein kommunikatives Potential? Dieser Band wirft einen völlig neuen, rhetoriktheoretischen Blick auf das Medium Fernsehen, der nicht nach der Überzeugungskraft einzelner Sendungen oder Institutionen fragt, sondern nach der kommunikativen Struktur des Mediums. Die Rhetoriker Joachim Knape und Anne Ulrich greifen dafür zentrale Konzepte aus der »Fernsehwissenschaft« heraus, diskutieren diese aus rhetorischer Perspektive und entwerfen ein Leistungsprofil des Mediums, das es erlaubt, erfolgversprechende Darstellungs- und Präsentationstechniken im Fernsehen zu bestimmen. Dies ermöglicht eine Neukonzeption des Mediums und gleichzeitig einen Überblick über die zentralen theoretischen Begriffe zum Fernsehen.

LECTURAS DEL AGUA (SÍMBOLOS, ECOCRÍTICA Y CULTURA DEL AGUA)
Authors: Núñez Eloy Martos
Published: December 2014

Existen diversos paradigmas sobre el estudio del agua que inciden en ella desde distintos puntos de vista. La gestión del agua es abordada desde las ciencias físicas y geológicas, y se soporta sobre tecnologías como la ingeniería hidráulica. En el aspecto histórico-social, se subraya la importancia de considerar el agua no como un recurso como parte esencial de una cosmovisión que vertebra el patrimonio cultural de una comunidad. Por ejemplo, en el estudio de los desastres (inundaciones, plagas, etc.) se ha puesto el énfasis en los datos hidroclimáticos, las respuestas sociales o la vulnerabilidad social. Sin embargo, la ecocrítica ha subrayado el papel de las fabulaciones folklóricas y de los Imaginarios en general para aportar una comprensión holística del problema. Los discursos fabulados admonitorios sobre las aguas y sus riesgos subrayan la importancia de estos lugares de memoria y de reforzar las identidades a través de estas ecoficciones y rituales. Se convierten, pues, en tradiciones útiles porque en realidad hablan de la sostenibilidad, la ética y la necesidad de preservar la memoria y la identidad cultural de la comunidad, frente a la depredación de la Naturaleza. De este modo, el conocimiento de esta cultura del agua no sólo contribuye a la adquisición de las competencias básicas de la educación, y en particular, a la educación literaria y del patrimonio, sino que contribuye a la gobernanza del agua y a la gestión sostenible y responsable de los recursos hídricos. Como indica E. Morin, la lectura y la literatura son una escuela de complejidad, y estos mitos inciden siempre en la multicausalidad de las acciones humanas.http://dx.doi.org/10.14572/nuances.v22i23.1749

PROJETOS DE LEI SOBRE MEDICALIZAÇÃO DA EDUCAÇÃO: BIOPOLÍTICA, CONTROLE E RESISTÊNCIA NA CONTEMPORANEIDADE
Authors: Cruz Murilo Galvão Amancio , Ferrazza Daniele De Andrade , Cardoso Jr Hélio Rebello
Published: December 2014

Na atualidade, os processos de medicalização da infância têm atingido os espaços escolares onde se proliferam rotulações diagnósticas acompanhadas da prescrição de psicofármacos. O presente trabalho tem como objetivo estudar, por meio da perspectiva genealógica foucaultiana, processos de medicalização da educação, com especial atenção a análise de projetos brasileiros de lei que servem à lógica medicalizante e ao estudo dos movimentos de resistência que surgiram com o intuito de denunciar as estratégias psicopatologizantes. Considera-se que os espaços escolares já submetidos aos processos de disciplinamento e normalização de corpos têm ganhado, através de projetos de lei, novos dispositivos de apoio aos discursos psiquiátricos. Estes, ao se apropriarem da infância considerada problema, têm disseminado diagnósticos e drogas psicofarmacológicas, processo que tem sido enfrentado por movimentos de resistência identificados com propostas de potencialização da pluralidade da vida.http://dx.doi.org/10.14572/nuances.v25i2.2645

Assim, teve-se como objetivo realizar uma revisão da literatura sobre o ensino colaborativo na educação infantil e verificar o conhecimento dos professores sobre esta estratégia pedagógica. A pesquisa foi realizada em Centros de Educação Infantil e escolas municipais de Educação Infantil, totalizando 4 unidades e 45 participantes. Os dados empíricos foram coletados por meio de um questionário fechado. Os resultados indicam o reconhecimento dos professores de Educação Infantil sobre a necessidade de apoio e suporte quanto ao ensino colaborativo, evidenciando a necessidade de uma formação continuada na atuação do professor de educação especial neste contexto.http://dx.doi.org/10.14572/nuances.v25i2.2714
ANÁLISE DE EPISÓDIOS INTERATIVOS DE CRIANÇAS SURDAS EM UMA INSTITUIÇÃO DE EDUCAÇÃO INFANTIL
Authors: Silvestre Carolina Oliveira Jimenez , Lourenço Erica Aparecida Garrutti de
Published: December 2014

Este estudo analisou episódios interativos entre duas crianças surdas, seus pares ouvintes e uma professora de Educação Infantil. Pautou-se num estudo de caso de caráter qualitativo, por meio da observação de uma turma de Educação Infantil em uma instituição particular da rede regular de ensino, entrevistas com a professora desse grupo de crianças e a coordenadora, análise do Projeto Político Pedagógico e aplicação de uma atividade dirigida com as crianças. Os episódios analisados revelaram que as crianças surdas desenvolvem ações conjuntas, independentemente de serem surdos ou ouvintes, pelo uso de gestos, sinais e demonstrações, pois compartilham necessidades de interação semelhantes na mesma faixa etária. As mediações da professora ocorreram pelo uso da Libras para favorecer a aprendizagem das crianças surdas. Entretanto, observou-se como necessidade que a instituição decida qual abordagem de comunicação utilizar, se o bilinguismo sucessivo ou simultâneo.http://dx.doi.org/10.14572/nuances.v25i2.2738
FALANDO DE TRANSIÇÕES: ENTRE A EDUCAÇÃO DE INFÂNCIA E A ESCOLA
Authors: Cardona Maria João
Published: December 2014

Este artigo pretende refletir sobre o processo de transição entre a educação pré-escolar e a escola, analisando algumas questões e fundamentos teóricos a considerar quando se aborda esta problemática. Começando pela definição do conceito de transição, numa primeira parte é feito o ponto da situação de algumas das principais pesquisas desenvolvidas nos últimos anos sobre esta temática. Num segundo momento são apresentados dados de pesquisas realizadas em Portugal com a finalidade de ouvir o ponto de vista de educadoras, professoras e crianças. A necessidade de desenvolver trabalhos de pesquisa sobre a transição entre a pré-escola e a escola é fundamental para uma melhor compreensão das implicações que o processo de transição tem na vida das crianças e dos fatores que influenciam positiva ou negativamente a forma como esta decorre. Esta análise tem implicações importantes em nível das práticas de formação, do trabalho realizado com as famílias e das práticas educativas desenvolvidas na educação pré-escolar e escolar.http://dx.doi.org/10.14572/nuances.v25i2.2772
A NATUREZA DAS ATIVIDADES MATEMÁTICAS PROPOSTAS EM TURMAS DE PRÉ-ESCOLA E PRIMEIRO ANO
Authors: Ciríaco Klinger Teodoro
Published: December 2014

Esse texto apresenta considerações sobre uma pesquisa realizada em nível de mestrado em educação e aborda resultados sobre a natureza das atividades matemáticas propostas por professoras de Educação Infantil (pré-escola) e do Ensino Fundamental (primeiro ano) durante o período em que realizamos a coleta de dados (agosto/2010 a julho/2011) ressaltando os assuntos que foram predominantes. Da análise dos dados conclui-se que: existe uma forte tendência no ensino de números e sistema de numeração, conteúdo que as professoras demonstram ter mais conhecimento; o padrão de ensino predominante é a utilização do livro didático/apostila, jogos e atividades exploratórias são pouco enfatizados no contexto das aulas. Contudo, cabe a ressalva de que uma proposta de trabalho com a Matemática na infância deve incorporar contextos do mundo real o que vai muito além de se trabalhar somente com o registro escrito e priorizar um conteúdo matemático em detrimento de outros.http://dx.doi.org/10.14572/nuances.v25i2.2816
A MÍDIA VÍDEO NA FORMAÇÃO DE PROFESSORES QUE ENSINAM MATEMÁTICA: ANÁLISE DE PESQUISAS BRASILEIRAS

Published: December 2014

O objetivo desse artigo é estudar em que contextos a mídia vídeo tem sido utilizada na formação de professores que ensinam matemática no Brasil. Nesse sentido, apresentamos os resultados de uma análise interpretativa de trabalhos que abordam a temática “mídia vídeo e a formação de professores que ensinam matemática” a partir de um levantamento de dissertações e teses (2000-2014) no Banco de Teses da CAPES. Identificamos quatro eixos temáticos e observamos que a mídia vídeo representada pela tecnologia de videoconferência é a mais recorrente nas investigações analisadas. Verificamos que no contexto nacional há poucos trabalhos cujo foco seja a mídia vídeo e a formação de professores que ensinam matemática, em particular que se foquem no uso do vídeo como recurso para professores repensarem suas práticas. Sendo assim, consideramos essas temáticas como campo fértil para investigação no Brasil.http://dx.doi.org/10.14572/nuances.v25i2.2849
ANALISE DE AMBIENTES DE GEOMETRIA DINAMICA COLABORATIVA DO PONTO DE VISTA DA ORQUESTRAÇÃO INSTRUMENTAL
Authors: Bellemain Franck
Published: December 2014

Existem muitos software implementando a geometria dinâmica desde os anos 80. Alguns deles propõem funcionalidades de comunicação síncrona permitindo a troca distante de conteúdos de geometria. Mesmo se a disponibilidade de tais funcionalidades é muito importante para dar suporte à colaboração entre parceiros, ela não garante essa colaboração assim como aprendizagens: a concepção e a conduta das situações de aprendizagem colaborativa continuam primordiais. Nesse sentido, nos interessar-nos-emos ao estudo, do ponto de vista da orquestração instrumental, do que três de tais ambientes de geometria dinâmica colaborativa (Geogebra, Tabulae e ‘Regua e compasso’) oferecem não somente para a comunicação síncrona, mas também para a concepção e conduta de situações de aprendizagem colaborativa.http://dx.doi.org/10.14572/nuances.v25i2.2936

Authors: De Moraes Rocha Katiane , Bittar Marilena
Published: December 2014

Nesse artigo apresentamos a articulação teórica que fundamentou a análise dos dados de uma pesquisa de mestrado no período de 2012-2013, que buscou compreender os processos vivenciados e os conhecimentos mobilizados e construídos por acadêmicos de um curso de Pedagogia tendo em vista a integração da tecnologia à sua futura prática. Para tanto, realizamos uma articulação teórica entre as Teorias da Instrumentação e da Abordagem dos Conhecimentos Pedagógicos Tecnológicos do Conteúdo, que favoreceu a análise do processo de integração da tecnologia na prática pedagógica dos futuros professores dos anos iniciais. Para ilustrar essa articulação trazemos alguns dados de nossa pesquisa oriundos de um projeto de extensão realizado com acadêmicos de um curso de Pedagogia. As análises evidenciam que essa proposta de formação favoreceu o processo de construção de conhecimentos de futuros professores para o ensino de Matemática.http://dx.doi.org/10.14572/nuances.v25i2.2970
“COM OLHOS DE CRIANÇA”: A METODOLOGIA DE PESQUISA COM CRIANÇAS PEQUENAS NO CENÁRIO BRASILEIRO
Authors: Rodrigues Silvia Adriana , Borges Tammi Flavie Peres , Da Silva Anamaria Santana
Published: December 2014

O movimento da Sociologia da Infância tem contribuído significativamente para a percepção das crianças como atores sociais, que estabelecem interações significativas com pessoas e instituições ao mesmo tempo em que desenvolvem estratégias de participação no mundo; pensá-las como atores é também considerá-las como informantes competentes em processos de investigação científica. No Brasil há um esforço para a produção de investimentos teóricos e desenvolvimento de estudos que contribuam para a construção de uma metodologia de pesquisa com crianças. Diante desta premissa, o presente artigo tem como proposta evidenciar as possibilidades da metodologia de pesquisa que elege a criança como protagonista; para tanto, resgatamos sumariamente algumas investigações realizadas no Brasil que adotaram a concepção de criança capaz de estabelecer relações, além de destacar as possibilidades do uso de instrumentos que visam amparar uma metodologia coerente e específica para a pesquisa com crianças.http://dx.doi.org/10.14572/nuances.v25i2.3188
