Early Identification of Transformation in the Proficiency Level of Critical Thinking
Authors: Swing Velmarie King
Published: March 2018

Critical Thinking (CT) in the nurse graduate continues to be a topic of concern in the academic and acute care settings. Few studies focus on early evaluation of Critical Thinking Skills (CTS). The purpose of this chapter is to show how the non-experimental, explanatory, quantitative study, the Kaplan CTIT, was employed to determine if a transformation in the level of CTS occurs within the first semester of associate degree nursing students. Participants completed the pretest in the first three weeks of classes. Posttests were given after course finals. A significant transformation in the level of CT occurred. The estimated change in CT test scores was 2.04, with 95% confidence. Implications for early measurement of CTS in nursing programs reveals if teaching methodology is providing the necessary input for developing CTS or if evaluation and changes are needed.
A User Friendly Guide to Successful Implementation of Care Mapping
Authors: Arena-Marshall Carrie Ann
Published: March 2018

The goal of care mapping in the clinical setting in undergraduate nursing education is to determine the student's ability to collect, present, and connect relevant data points in order to evaluate and understand the medical plan of care and to develop a priority based nursing plan of care. This same process can be utilized across all health science education programs. The purpose of this chapter is to share how the author has modified the traditional concept map tool to a more user friendly format and to present a process of implementation that may be used in the clinical setting as part of any undergraduate health science program. The benefits of such an implementation are that of more enriched learning to include the development of critical thinking skills, the use of a common sense approach, and the recognition of the patient as a holistic being.

In collaboration with the National Institutes of Health and other national institutes, nursing scholars have developed the blueprint which should guide the integration of genomic science into nursing curriculum not only in the United states but also internationally. Assiduously, effort was devoted to espouse the life-threatening risks associated with nursing profession even at the outbreak of deadly emerging infectious disease such Ebola virus which has a very high case fatality rate. Besides, this pathogenic disease is without known cure. Many of the self-fulfilling psychological attributes, and prospects of the profession were discussed and as well as the overt challenges.
Comparison of Baccalaureate Nursing Students' Experience of Video-Assisted Debriefing vs. Oral Debriefing Following High-Fidelity Human Simulation
Authors: Royle Colleen , Hargiss Kathleen
Published: March 2018

High-Fidelity Human Simulation (HFHS) is used in many disciplines, including nursing, as an innovative teaching pedagogy that offers an active learning process. The simulation process involves a number of stages with the most critical stage identified as debriefing. The main focus of debriefing is to stimulate reflection and encourage communication while exploring the emotions of the participants. These emotions assist in framing the experience that aids in enhancement of learning for the student. This quantitative, quasi-experimental study explored the comparison of two debriefing processes, video-assisted and oral, by assessing the students' opinion of the debriefing experience and the students' rating of the importance of the debriefing experience. Participants were first semester baccalaureate nursing students. The overall finding and the four subscales for both dependent variables showed no statistical significance. This article provides further evidence to guide educators to a preferred method of debriefing students after a simulated experience.

Authors: Ziemba Rosemary , Cuker Benjamin E. , Stein Joyce , Meuninck Rebecca , Wan Jiayi Angela
Published: March 2018

Emerging research shows adverse health outcomes such as diabetes, obesity, cancer, and neurotoxicity from water pollutants such as flame retardants, endocrine disruptors, and pharmaceuticals. Medical waste and energy use affects water quality and quantity. This chapter provides strategies for health professionals to promote water stewardship at personal, organizational and policy levels. Organizations such as Health Care Without Harm, Alliance of Nurses for Healthy Environments and the Ecology Center offer resources for improving education of health professionals and provide allies for change. Individual advocacy through writing op-eds, policy briefs, meeting with legislators and participation in coalitions allows health professionals to interpret the science behind the need for policy changes. Recommendations for health care curricula prepare students to develop sustainable practices through inter-professional collaboration. Environmentalists can use this information to better engage health professionals in promoting change.
Challenges to Implementing IT Support for Evidence Based Practice Among Nurses and Assistant Nurses
Authors: Rexhepi Hanife , Persson Anne
Published: March 2018

When practitioners make decisions as well as treat and care for patients they interpret patient specific information according to evidence based medical knowledge. This process is complex as evidence is infrequently available in a form that can be acted upon at the time decisions must be made. The aim of this paper is to (1) explore how primary, secondary and municipality care in Sweden work with the process of managing knowledge, (2) explore how nurses and assistant nurses experience availability of medical knowledge when and where they need it and (3) conditions for developing a coherent IT-based knowledge portal for different areas of knowledge bases in healthcare. The results show significant deficiencies in the knowledge management process of the participating organizations. The knowledge management processes are not embedded in business processes, activities and relationships, which cause major difficulties for practitioners to keep up with the latest medical evidence.
The Development of BelRAI, a Web Application for Sharing Assessment Data on Frail Older People in Home Care, Nursing Homes, and Hospitals
Authors: Vanneste Dirk , Declercq Anja
Published: March 2018

As the complexity of caregiving rises and surpasses traditional models of care, the need for comprehensive and integrated assessment systems increases. The use of standardised and computerised data—available to those who must make decisions—has become paramount. In Belgium, the BelRAI Web application has been developed to support the use of interRAI assessment instruments in a multidisciplinary way and to exchange client-centred information across care settings. This chapter describes the particularities of BelRAI, the security aspects, the support tools, the gradual process of implementation, the dos and don'ts, the pros and cons, and the challenges for the future. The benefits seem to overrule the drawbacks, but it has also become clear that only a significant expenditure on resources with regard to adequate staffing in healthcare environments, appropriate information technology, and training facilities can contribute to a successful introduction, maintenance, and full exploitation of this innovative health information system.
Trust-Based Analytical Models for Secure Wireless Sensor Networks
Authors: Usman Aminu Bello , Gutierrez Jairo
Published: March 2018

In this chapter, the authors hypothesize that in the design of a trust-based routing protocol, the exploration of the peers' routing attributes could significantly improve trust evaluation accuracy. In this regard, they study the properties of complex networks and their impact on trust and reputation propagation and evaluation. They start by illustrating the structural transitivity in the network and its approximation. They then proceed to present the theoretical and analytical relationship between trust and reputation model accuracy, average structural transitivity between peers, average shortest path between peers, and energy consumed by peers for trust and reputation propagation and evaluations. The experimental studies using simulation have further supported the results of the analytical study. In this chapter, the authors are paving a new angle of research on exploring the complex network properties impact on trust and reputation evaluation between wireless peers.
Compliance of Electronic Health Record Applications With HIPAA Security and Privacy Requirements
Authors: Farhadi Maryam , Haddad Hisham M. , Shahriar Hossain
Published: March 2018

Electronic health record (EHR) applications are digital versions of paper-based patients health information. EHR applications are increasingly being adopted in many countries. They have resulted in improved quality in healthcare, convenient access to histories of patient medication and clinic visits, easier follow up of patient treatment plans, and precise medical decision-making process by doctors. EHR applications are guided by measures of the Health Insurance Portability and Accountability Act (HIPAA) to ensure confidentiality, integrity, and availability. However, there have been reported breaches of protected health identifier (PHI) data stored by EHR applications. In many reported breaches, improper use of EHRs has resulted in disclosure of patient's protected health information. The goal of this chapter is to (1) provide an overview of HIPAA security and privacy requirements; (2) summarize recent literature works related to complying with HIPAA security and privacy requirements; (3) map some of the existing vulnerabilities with HIPAA security rules.

A Semiotic Examination of the Security Policy Lifecycle
Authors: Lapke Michael
Published: March 2018

Major security breaches continue to plague organizations decades after best practices, standards, and technical safeguards have become commonplace. This worrying trend clearly demonstrates that information systems security remains a significant issue within organizations. As policy forms the basis for practice, a major contributor to this ongoing security problem is a faulty security policy lifecycle. This can lead to an insufficient or worse, a failed policy. This chapter is aimed at understanding the lifecycle by analyzing the meanings that are attributed to policy formulation and implementation by the stakeholders involved in the process. A case study was carried out and a “snapshot in time” of the lifecycle of IS security policy lifecycle at the organization revealed that a disconnect is evident in the security policy lifecycle.
Intrusion Detection Systems Alerts Reduction
Authors: Akremi Aymen , Sallay Hassen , Rouached Mohsen
Published: March 2018

Investigators search usually for any kind of events related directly to an investigation case to both limit the search space and propose new hypotheses about the suspect. Intrusion detection system (IDS) provide relevant information to the forensics experts since it detects the attacks and gathers automatically several pertinent features of the network in the attack moment. Thus, IDS should be very effective in term of detection accuracy of new unknown attacks signatures, and without generating huge number of false alerts in high speed networks. This tradeoff between keeping high detection accuracy without generating false alerts is today a big challenge. As an effort to deal with false alerts generation, the authors propose new intrusion alert classifier, named Alert Miner (AM), to classify efficiently in near real-time the intrusion alerts in HSN. AM uses an outlier detection technique based on an adaptive deduced association rules set to classify the alerts automatically and without human assistance.
Internet Crime and Anti-Fraud Activism
Authors: Zingerle Andreas , Kronman Linda
Published: March 2018

Scambaiting is a form of vigilantism that targets internet scammers who try to trick people into advance fee payments. In the past, victims were mainly contacted by bulk emails; now the widespread use of social networking services has made it easier for scammers to contact potential victims – those who seek various online opportunities in the form of sales and rentals, dating, booking holidays, or seeking for jobs. Scambaiters are online information communities specializing in identifying, documenting, and reporting activities of scammers. By following scambaiting forums, it was possible to categorize different scambaiting subgroups with various strategies and tools. These were tested in hands-on sessions during creative workshops in order to gain a wider understanding of the scope of existing internet scams as well as exploring counter strategies to prevent internet crime. The aim of the workshops was to recognize and develop diverse forms of anti-scam activism.
Improving Interferometry Instrumentation by Mixing Stereoscopy for 2π Ambiguity Solving
Authors: Karsenty Avi , Lichtenstadt Yaron , Naeim Sagi , Arieli Yoel
Published: March 2018

Phase measurements obtained by high-coherence interferometry are restricted by the 2π ambiguity to height differences smaller than λ/2. A further restriction considers linear and nonlinear aberrations evolving in most interferometric systems due to the CCD-type array detectors. The authors present a new method to overcome the 2π ambiguity in interferometry when using a stereoscopic approach. In this method, a reconstructed wavefront reflected from an object was propagated into two different angles to obtain two different images of the object. These two different images were subsequently processed by stereo algorithms to resolve the 2π ambiguity. Such a method of wavefront propagation may enable several applications such as focusing and resolving the 2π ambiguity, as described in the article.
O Dante Alighieri de Antonio Gramsci: um realismo sem mimese
Authors: Brunello Yuri
Published: March 2018

Antonio Gramsci constrói nos Cadernos do cárcere uma leitura ‘anticroceana’ do Canto X do Inferno de Dante Alighieri. É uma interpretação baseada na concepção da lacuna textual – manifestada pelo silêncio de Dante frente a Cavalcante de’ Cavalcanti, um dos protagonistas do canto dantesco – como uma estratégia de natureza cultural e, ao mesmo tempo, de valor tanto político quanto social; ou seja, a poesia não é reduzida ao ‘poético’. Gramsci, de fato, recusa a visão da literatura como algo esterilmente ‘superestrutural’. Ler o Canto X, ao contrário, significa entender a poesia dantesca não como uma mimese ou uma representação, mas como a própria realidade imanente: parte de uma totalidade orgânica, na qual cada elemento – e, portanto, um elemento cultural como uma obra literária – constitui uma articulação do conjunto. O presente estudo pretende indicar, no tipo de exegese gramsciana do Canto X, uma tentativa de encontrar nas lacunas textuais não a manifestação, como acreditava Benedetto Croce (1921), da dimensão inefável e pré-lógica da intuição, mas os pressupostos para que o leitor exerça um papel ativo e criativo: racional, de articulação ideológica e de conexão entre o nível cultural, político e econômico da sociedade entendida como um todo.
Teleost Basophils Have IgM-Dependent and Dual Ig-Independent Degranulation Systems
Authors: Odaka Tomoyuki , Suetake Hiroaki , Maeda Tomoki , Miyadai Toshiaki
Published: March 2018

Recently, mammalian basophils have been highlighted as having roles in allergy and antiparasitic immunity; however, there is little information about the functions and evolutionary origin of basophils, because they are the least abundant leukocyte in most vertebrates. In this study, we characterized the teleost basophils that are abundant in the peripheral blood of fugu (Takifugu rubripes). Fugu basophils have two distinct granules: reddish-purple and dark violet ones. Teleost fish do not have IgG and IgE, but we found that fugu IgM bound on the surface of the basophils, and the cross-linked IgM induced degranulation of both types of granules. This indicates that teleost basophils can be activated in an Ab-dependent manner. Furthermore, papain induced the degranulation of the reddish-purple granules, which contain histamine, and the released granules stimulated the migration of various leukocytes. In contrast, chitin elicited the degranulation of the dark violet granules, which resulted in CD4+ T cell–specific migration. Thus, fugu basophils control immune responses via two distinct Ab-independent mechanisms. In addition, fugu basophils endocytosed soluble Ag and expressed MHC class II and B7-H1/DC. These findings suggested that fugu basophils can interact with T cells as APCs. Thus, the Ab-dependent basophil activation predates the emergence of IgG and IgE, and fish basophils exhibit different dynamics and features of degranulation to distinct stimuli compared with mammalian basophils. Some features of teleost basophils are more similar to those of mammalian mast cells than to those of mammalian basophils.

Published: March 2018

Background: African specific studies on the factors associated with the growth pattern of children are needed to guide evidence and develop effective population-based interventions that can be tailored to the unique African context.Purpose: The purpose of this study was to determine the socio-economic correlates of body mass index (BMI) of primary and secondary school children in Ebonyi State, which is situated in south-eastern Nigeria.Methodology: This was a quantitative, cross-sectional study that utilised clustering and stratified sampling techniques to select 1000 learners from primary and secondary schools located in Abakaliki local government area. Apart from a questionnaire, a Mettler weighing scale was also used for data collection. A generalised linear model was used to test the association between the participants’ socio-demographic characteristics and their BMI.Result: BMI was positively related to female gender but negatively related to age and level of education. The mode of cooking, who the participants live with and how they get to school also predicted changes in BMI. Other variables like mother’s occupation and family’s mode of transport were also associated with BMI changes while father’s level of education, mother’s level of education, father’s occupation and the type of residence did not have any statistical relationship with BMI.Conclusion: The present study shows that the BMI of school children is influenced by the socio-demographic characteristics surrounding them. Therefore, efforts should be made to improve the socio-economic standing of families in this community.

Authors: Yang Bowen , Zhou Shijun , Ju Weijie
Published: March 2018

Engage is a new form of mobile application that connects students studying English with teachers in real-time via their smartphones. Students receive target language through preparation dialogues, and then apply it to a role-play with a teacher. The conceptualization and development of Engage follows the user-centred design approach; and the product was built through multiple iterations: in the first iteration, students were invited to try out a paper mock-up; in the second iteration, students tried out a mobile prototype; in the external test, a fully functional application was released to App Store between October 25 and November 20, 2012, and 326 users downloaded it. The application was well-received by these test users, reflected in the post-study survey, student ratings, and students’ usage records. The external tests proved that the technical environment of the application was feasible for production; and the operationalization of the teacher service and cost model were also proven to be feasible and scalable.
Electronic Feedback: Pedagogical Considerations for the Implementation of Software
Authors: García-Yeste Miguel
Published: March 2018

As university lecturers, we often struggle to provide our students with good quality feedback in a consistent manner. This is usually caused by the increasing imbalance in teacher-student ratios (Hounsell et al., 2008), as well as the pressure of academic life and the lack of time (Sadler, 2010). In addition, assessment practices should be transparent enough to ensure all students are evaluated in a similar way (O’Donovan et al., 2004), especially when different instructors teach different groups of students taking the same course. This paper, which focuses on designing a feedback scheme that helps instructors to provide good quality feedback in a consistent manner, begins with a needs analysis based on the author’s experience as an instructor of academic writing in English. A literature review follows, focusing on: (a) the scholarship on feedback in higher education; and (b) the research on the use of technology for the provision of feedback. Finally, a feedback scheme is presented, and some guidelines for its implementation are provided.

Foi-se o tempo em que a pura estética era a parte mais importante em um produto, também não é mais a época onde só a função basta. Hoje, se está em um período que o conjunto da obra e uma boa experiência por parte dos usuários com relação a produtos que satisfaçam suas necessidades, se fazem essenciais. Às vezes, parece que há um esquecimento por parte dos profissionais envolvidos em colocar os usuários em primeiro plano, no centro de tudo. Com o Design Think ing, além de decretar-se o fim às velhas ideias, o usuário passa a ser prioridade, e não se está mais em busca daquilo que ele diz que quer ou que pelo menos, acha que quer, e sim, de um novo desafio: captar os seus sentimentos e até os seus sonhos. Busca-se neste trabalho analisar junto ao Design Emocional um estudo sobre a interação destes agentes - usuário e produto - para então, ficar mais fácil criar e entender à relação empática existente entre eles.

Authors: Silva Carina Scandolara da , Straioto Ricardo G. T. , Figueiredo Luiz Fernando Gonçalves de
Published: March 2018

O Design é um processo estratégico de resolução de problemas que impulsiona a inovação, o sucesso do negócio e a qualidade de vida através de produtos, sistemas, serviços e experiências inovadoras (ICSID, 2015). Inovar é um processo de alavancar a criatividade para gerar valor de novas maneiras através de novos produtos, serviços e negócios (JONASH e SOMMERLATTE, 2000). Quando se tem uma inovação é possível fazer o registro de uma nova patente. Os registros de marcas, desenhos industriais, indicações geográficas, concessões de patentes e as distintas modalidades de transferência de tecnologia, na economia do criativa e do conhecimento, se transformam em diferenciais competitivos, estimulando o surgimento constante de novas identidades e soluções técnicas (INPI, 2017). Cada objeto de design é o resultado de um processo de desenvolvimento, cujo andamento é determinado por condições e decisões (BÜRDEK, 2010). Tendo isso em vista, percebe-se como o processo de desenvolvimento de design envolve conhecimentos e habilidades sistêmicas. Desta forma, este trabalho objetiva evidenciar de forma sistêmica o potencial de criativo de um núcleo de desenvolvimento de design que atua com abordagem sistêmica, relacionando suas competências em serviços com a política brasileira de proteção do design, afim de salientar as conectividades entre serviços e produção de patentes. Os procedimentos metodológicos adotados para tal envolvem uma pesquisa de natureza aplicada, com abordagem qualitativa, objetivo exploratório e com procedimentos técnicos envolvendo levantamento bibliográfico e estudo de caso, por envolver o estudo profundo e exaustivo de um objeto pesquisa - o núcleo de abordagem sistêmica do design - de maneira que se permita o amplo e detalhado conhecimento do seu modelo de atuação em serviços, verificando seu potencial de inovação e de produção de patentes (SILVA e MENEZES, 2005).Como resultado, este artigo propõe uma visão sistêmica do modelo de atuação do núcleo de design estudado que evidencia a conexão entre as atividades e serviços de design com a produção de patentes no Brasil, além de discutir o potencial de inovação do núcleo e do design de forma geral.Keywords: design; abordagem sistêmica; serviços; inovação; patentes1.

Published: March 2018

Abstract. Observational constraint of simulated aerosol and cloud properties is an essential part of building trustworthy climate models for calculating aerosol radiative forcing. Models are usually tuned to achieve good agreement with observations, but tuning produces just one of many potential variants of a model, so the model uncertainty cannot be determined. Here we estimate the uncertainty in aerosol effective radiative forcing (ERF) in a tuned climate model by constraining 4 million variants of the HadGEM3-UKCA aerosol-climate model to match nine common observations (top-of-atmosphere shortwave flux, aerosol optical depth, PM2.5, cloud condensation nuclei, concentrations of sulphate, black carbon and organic carbon, as well as decadal trends in aerosol optical depth and surface shortwave radiation.) The model uncertainty is calculated by using a perturbed parameter ensemble that samples twenty-seven uncertainties in both the aerosol model and the physical climate model. Focusing over Europe, we show that the aerosol ERF uncertainty can be reduced by about 30 % by constraining it to the nine observations, demonstrating that producing climate models with an observationally plausible base state can contribute to narrowing the uncertainty in aerosol ERF. However, the uncertainty in the aerosol ERF after observational constraint is large compared to the typical spread of a multi-model ensemble. Our results therefore raise questions about whether the underlying multi-model uncertainty would be larger if similar approaches as adopted here were applied more widely. It is hoped that aerosol ERF uncertainty can be further reduced by introducing process-related constraints, however, any such results will be robust only if the enormous number of potential model variants is explored.
Implementing spatially explicit seed and pollen dispersal in the individual-based larch simulation model: LAVESI-WIND 1.0
Authors: Kruse Stefan , Gerdes Alexander , Kath Nadja J. , Herzschuh Ulrike
Published: March 2018

Abstract. It is of major interest to estimate the feedback of arctic ecosystems to the global warming we expect in upcoming decades. The speed of this response is driven by the potential of species to migrate, tracking their climate optimum. For this, sessile plants have to produce and disperse seeds to newly available habitats, and pollination is needed for the seeds to be viable. These two processes are also the vectors that pass genetic information through a population. A restricted exchange among subpopulations might lead to a maladapted population due to diversity losses. Hence, a realistic implementation of these dispersal processes into a simulation model would allow an assessment of the importance of diversity for the migration of plant species in various environments worldwide. To date, dynamic global vegetation models have been optimised for a global application and overestimate the migration of biome shifts in currently warming temperatures. We hypothesise that this is caused by neglecting important fine-scale processes, which are necessary to estimate realistic vegetation trajectories. Recently, we built and parameterised a simulation model LAVESI for larches that dominate the latitudinal treelines in the northernmost areas of Siberia. In this study, we updated the vegetation model by including seed and pollen dispersal driven by wind speed and direction. The seed dispersal is modelled as a ballistic flight, and for the pollination of seeds produced, we implemented a wind-determined and distance-dependent probability distribution function using a von Mises distribution to select the potential pollen donor. This individual-based and spatially explicit implementation of both dispersal processes makes it easily feasible to inherit plant traits and genetic information to assess the impact of migration processes on the genetics. The final model can substantially help in unveiling the important drivers of migration dynamics and, with this, guide the improvement of recent global vegetation models.
The Effects of Internal Marketing on Turnover Intentions in Knowledge Workers in the IT Sector
Authors: Ladelsky Limor Kessler , Jacob Weisberg
Published: March 2018

This study suggests applying the concept of internal marketing to combat turnover intentions in knowledge workers in the IT sector. Internal marketing sees all employees as the firm's customers. The major hypothesis examined here is that when employees feel that a firm considers and treats them like customers, it increases employment commitment and reduces turnover intentions. A multivariate hierarchical regression analysis and structural equation modelling (SEM) incorporating demographic, personal, organizational and external variables were used to identify the unique contribution of internal marketing to turnover intentions. The findings showed a negative correlation between internal marketing and turnover intention that contributed significantly to the explained variance beyond the effects of other independent variables. These results are discussed in the light of their theoretical and practical implications and in particular that IT organizations should consider adopting internal-marketing practices to reduce turnover intention and hence voluntary turnover.

La Configuración Constitucional del Sistema Tributario Nicaragüense
Authors: Argueta Jaen Julio
Published: March 2018

Este artículo trata sobre el desarrollo de las cláusulas tributarias constitucionales en Nicaragua. El propósito general es presentar una sucinta sistematización de la configuración constitucional del sistema tributario nicaragüense. Entre los objetivos específicos que subyacen están: reconocer los antecedentes constitucionales tributarios, analizar los principios tributarios constitucionales vigentes, valorar la reserva de ley tributaria y ubicar el sistema tributario constitucional nicaragüense en relación al derecho comparado. La investigación es teórico-dogmática, en esta se analiza la normatividad y axiología tributaria constitucional con referencias históricas y comparadas. Entre los principales hallazgos están los siguientes: Desde los albores del constitucionalismo nicaragüense, se observa como manifiesta y progresivamente, aunque también de forma lenta, se ha configurado la materia tributaria a nivel de la Carta Magna. Hay una temprana adopción constitucional del principio de progresividad tributaria, primero de forma taxativa y en la actualidad de forma implícita. No obstante, se relacionan algunas evidencias sobre la existencia de un sistema tributario regresivo. Existe una adecuada reserva de ley de la materia tributaria, tanto para el establecimiento de los tributos como para la exención de los mismos. La conclusión se inclina por robustecer el texto fundamental con una determinación taxativa del principio de progresividad tributaria.

Living in an age of immense social, cultural, economic, and political changes and momentous processes of modernization, John Dewey (1859-1952) was a philosopher of reconstruction who reinvented himself and his approaches many times over his long lifespan. He emphasized the need for continual reinvention on many diverse levels. As a philosopher of democracy and education, he clearly saw that renewal and reconstruction are at the heart of democratic living together and educational growth. Dewey’s philosophy and educational approach was pioneering in his elaborate reflections on the interrelations between democracy and education, especially in the contexts of modern societies. In his 1938 essay “Democracy and Education in the World of Today” he claimed it “is obvious that the relation between democracy and education is a reciprocal one, a mutual one, and vitally so. Democracy is itself and educational principle, and educational measure and policy.” (LW 13: 294) He further observed“… every generation has to accomplish democracy over again for itself; … its very nature, its essence, is something that cannot be handed on from one person or one generation to another, but has to be worked out in terms of needs, problems and conditions of the social life of which, as the years go by, we are a part, a social life that is changing with extreme rapidity from year to year.” (LW 13: 299)
Chapter 3: Education and Social Self-Creation between Solid and Liquid Modernity
Authors: Garrison Jim
Published: March 2018

This essay intersects John Dewey’s pragmatism with Zygmunt Bauman’s sociological thinking. It explores the creative dimension of Dewey’s constructivism with an emphasis on social self-creation. Bauman’s notions of solid and liquid modernity – among other things his ideas about conditions of time/space and work – supplement Deweyan constructivism by specifying some characteristics of the contemporary social environment that contribute to the social construction of the mind and self. The paper situates the Cologne International Teacher Education Laboratory within the flux of liquid modernity before discussing what Dewey’s theory of inquiry may contribute toward teachers living a more enthusiastic, free, and more creative professional life. The paper concludes with a call for teachers and teacher educators to join with us in forming what Dewey would call a “public” of concerned, committed, and creative educators.
"Likes" and "followers" on social portals as a way of searching for personal identity
Authors: Andrzejewski Adam
Published: March 2018

The publication focuses on the connection between humans' personal identity and activity on social networks. Facebook and Instagram are a kind of (cyber-communication) sphere in which we are able to communicate with everyone who belongs to these (cyber-)communities. It allows us to publish our photos, memories, current activities, and videos while simultaneously allowing the portal’s other users to observe our life and expression of our Self. In this (cyber-)social space, people are able to create their image and (cyber-)identity in a psychological and social context, encounter a variety of (personal) experiences, but also gain popularity – sometimes at all cost, at the expense of their health and life.
The following issues are discussed in the publication:
1. (People's cyber-)identity created on the social networks: Facebook and Instagram.
2. Self-esteem depending on the number of "likes."
3. "Ultimate selfie" - the popularity for which you pay with your life.
Morgantina Revisited: An Architect’s Recollections
Authors: Edlund-Berry Ingrid , Kyllingstad Røyne
Published: March 2018

The ancient Greek site of Morgantina in central Sicily is well known to students of architecture, city planning, numismatics, and other related fields in Classical Studies. It was first settled on the Cittadella hill in the Bronze and Iron Ages. The arrival of Greeks in the early sixth century BC resulted in the creation of a settlement also on Cittadella with a shrine (naiskos) decorated with brightly colored architectural terracottas and with houses. Imported Greek pottery found within the settlement and in the tombs bears witness to extensive trade, and Morgantina also minted its own coins.

Mammary Paget disease is the intraepidermal adenocarcinoma of the nipple area which is characterized usually by a well-demarcated eczematous plaque. Reflectance confocal microscopy (RCM), is an in vivo noninvasive diagnostic tool with a high-resolution imaging of the skin, almost comparable to conventional histology. RCM findings of Paget disease are limited in the literature. Most of the reported cases are the extramammary type. In this report, we aimed to evaluate the RCM findings of a non-pigmented mammary Paget disease in a 65 year-old woman.
Immunoreactivity of Wilms tumor 1 (WT1) as an additional evidence supporting hemangiomatous rather than inflammatory origin in the etiopathogenesis of angiolymphoid hyperplasia with eosinophilia

Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare vascular proliferative disorder mainly located in the periauricular region. The etiopathogenesis of ALHE is unknown, and it is still controversial as to whether the entity represents a benign vascular neoplasm or an inflammatory process.

Aim: Recently, the intracytoplasmic staining pattern of Wilms tumor 1 (WT1) on immunohistochemistry has highlighted true vascular neoplasms, such as microvenular hemangioma, tufted angioma, and spindle cell hemangioma, which has made it helpful to distinguish ALHE from vascular malformations, as there is a negative staining pattern in the other entities. We aimed to investigate the immunoreactivity of ALHE specimens for WT1 as well as glucose transporter protein 1 (GLUT1) immunohistochemistry, an important and sensitive marker for the diagnosis of infantile hemangioma, which recently has been described to label other hemangiomas, such as verrucous hemangioma.

Material and methods: Clinical data and histopathological specimens from patients diagnosed with ALHE were reviewed, and immunohistochemical staining and microscopic analysis for WT-1 and GLUT1 were performed.

Results: Intracytoplasmic endothelial staining of WT1 was detected in 19 of 20 ALHE specimens. GLUT1 was not detected in any ALHE specimen.

Conclusions: We conclude that ALHE may represent a true hemangioma (i.e., benign vascular neoplasia) characterized by an eosinophil- and lymphocyte-rich inflammatory component as opposed to the reactive inflammatory dermatosis with a positive intracytoplasmic staining pattern for WT1. As far as we are aware, WT1 staining for ALHE has not been described to date.
Abordagem multiparadigmática em estudos organizacionais: avanços e limitações
Authors: Amboni Nério , Caminha Daniel Ouriques , Andrade Rui Otávio Bernardes de , Fernandes Maurício
Published: March 2018

This paper aims to discuss the developments and limitations of multiparadigmatic approach to developing organizational studies. The model of the four paradigms (functionalist, interpretive, radical humanist and radical structuralist) proposed by Burrell and Morgan (1979) accelerated the proliferation of competing perspectives, besides generating the polarization and segregation. Each paradigm is treated in a unique perspective and therefore incommensurable with another paradigm, against the scholars who defend the communication between paradigms. The pluralistic view is relevant because it encourages scholars to see organizations in different prisms to succumb to the reductionist view of the theory of organizations, and encourage the development of new perspectives for organizational analysis. However, the use of multiple paradigms also presents limits, since the researcher when dealing with different approaches can be without reference or justification, besides sometimes having difficulty to be away from the dominant paradigm. All these joints and paradigmatic joints can be made, provided that the researcher always has a reference and a basis, in order to maintain the coherence and the consistency of what is being researched.
Resolução integrada de problemas do planejamento do transporte público: foco na tabela de horários e no escalonamento de veículos com frota heterogênea

Published: March 2018

In this paper, we propose a new Integer Linear Programming model, based on a time-space network that integrates the timetable generation problem and the vehicle scheduling problem with heterogeneous fleet. A difference of this approach consists in considering the demand for the timetable redefinition and the vehicle scheduling, factor rarely applied in optimization models of the transportation system. We applied real and large random instances. The results indicate that the model may contribute to optimizing the public transport planning leading to significant savings in terms of scheduled vehicles. Moreover, as the timetable changes are fairly short, it is slightly modified, minimally modifying the passengers routine, which enables the application of these approaches to real context.
