Influence of Ultrasonic Surface Rolling on Microstructure and Wear Behavior of Selective Laser Melted Ti-6Al-4V Alloy
Authors: Wang Zhen , Xiao Zhiyu , Huang Chuanshou , Wen Liping , Zhang Weiwen
Published: October 2017

The present article studied the effect of ultrasonic surface rolling process (USRP) on the microstructure and wear behavior of a selective laser melted Ti-6Al-4V alloy. Surface characteristics were investigated using optical microscope, nano-indentation, scanning electron microscope, transmission electron microscope and laser scanning confocal microscope. Results indicated that the thickness of pore-free surfaces increased to 100~200 μm with the increasing ultrasonic surface rolling numbers. Severe work hardening occurred in the densified layer, resulting in the formation of refined grains, dislocation walls and deformation twins. After 1000 N 6 passes, about 15.5% and 14.1% increment in surficial Nano-hardness and Vickers-hardness was obtained, respectively. The hardness decreased gradually from the top surface to the substrate. Wear tests revealed that the friction coefficient declined from 0.74 (polished surface) to 0.64 (USRP treated surface) and the wear volume reduced from 0.205 mm−3 to 0.195 mm−3. The difference in wear volume between USRP treated and polished samples increased with sliding time. The enhanced wear resistance was concluded to be associated with the improvement of hardness and shear resistance and also the inhibition of delamination initiation.
α-Synuclein Regulates Neuronal Cholesterol Efflux
Authors: Hsiao Jen-Hsiang , Halliday Glenda , Kim Woojin
Published: October 2017

α-Synuclein is a neuronal protein that is at the center of focus in understanding the etiology of a group of neurodegenerative diseases called α-synucleinopathies, which includes Parkinson’s disease (PD). Despite much research, the exact physiological function of α-synuclein is still unclear. α-Synuclein has similar biophysical properties as apolipoproteins and other lipid-binding proteins and has a high affinity for cholesterol. These properties suggest a possible role for α-synuclein as a lipid acceptor mediating cholesterol efflux (the process of removing cholesterol out of cells). To test this concept, we “loaded” SK-N-SH neuronal cells with fluorescently-labelled cholesterol, applied exogenous α-synuclein, and measured the amount of cholesterol removed from the cells using a classic cholesterol efflux assay. We found that α-synuclein potently stimulated cholesterol efflux. We found that the process was dose and time dependent, and was saturable at 1.0 µg/mL of α-synuclein. It was also dependent on the transporter protein ABCA1 located on the plasma membrane. We reveal for the first time a novel role of α-synuclein that underscores its importance in neuronal cholesterol regulation, and identify novel therapeutic targets for controlling cellular cholesterol levels.

Published: October 2017

One of the deadliest cancers among women is a breast cancer. Research has shown that two natural substances occurring in propolis, caffeic acid (CA) and caffeic acid phenethyl ester (CAPE), have significant anticancer effects. The purpose of our in vitro study was to compare cytotoxic activity and migration rate inhibition using CA and CAPE (doses of 50 and 100 µm) against triple-negative, MDA-MB-231 breast adenocarcinoma line cells, drawn from Caucasian women. Viability was measured by XTT-NR-SRB assay (Tetrazolium hydroxide-Neutral Red-Sulforhodamine B) for 24 h and 48 h periods. Cell migration for wound healing assay was taken for 0 h, 8 h, 16 h, and 24 h periods. CAPE displayed more than two times higher cytotoxicity against MDA-MB-231 cells. IC50 values for the XTT assay were as follows: CA for 24 h and 48 h were 150.94 µM and 108.42 µM, respectively, while CAPE was 68.82 µM for 24 h and 55.79 µM for 48 h. For the NR assay: CA was 135.85 µM at 24 h and 103.23 µM at 48 h, while CAPE was 64.04 µM at 24 h and 53.25 µM at 48 h. For the SRB assay: CA at 24 h was 139.80 µM and at 48 h 103.98 µM, while CAPE was 66.86 µM at 24 h and 47.73 µM at 48 h. Both agents suspended the migration rate; however, CAPE displayed better activity. Notably, for the 100 µM CAPE dose, motility of the tested breast carcinoma cells was halted.

Published: October 2017

Curcumin has been proven to have a weight-loss effect in a menopausal rat model induced by ovariectomy. However, the effects of curcumin on gut microfloral communities of ovariectomized (OVX) rats remains unclear. Here, we used high-throughput 16S rDNA sequencing to explore the effects of curcumin on microbial diversity in the gut of OVX rats. Female Wistar rats were subjected to either ovariectomy or a sham operation (SHAM group). The OVX rats were treated with vehicle (OVX group) or curcumin (CUR group) by oral gavage. After 12-week treatments, the weights of the bodies and uteri of rats were recorded, the levels of estradiol in the serum were assayed by electrochemiluminescence immunoassay (ECLIA). Then, the fragments encompassing V3–V4 16S rDNA hypervariable regions were PCR amplified from fecal samples, and the PCR products of V3–V4 were sequenced on an Illumina MiSeq for characterization of the gut microbiota. Our results showed that, compared to rats in the SHAM group, rats in the OVX group had more weight gain and lower levels of estradiol in the serum, and curcumin could cause significant weight loss in OVX rats but did not increase the levels of estradiol. Sequencing results revealed the presence of 1120, 1114, and 1119 operational taxonomic units (OTUs) found in the SHAM, OVX, and CUR groups, respectively. The percentage of shared OTUs was 86.1603%. Gut microbiota of rats from the SHAM or CUR group had higher levels of biodiversity and unevenness estimations than those from the OVX group. At the phyla level, compared to rats in SHAM group, rats in the OVX group had a higher ratio of phyla Firmicutes and Bacteroidetes in the gut; at the genus level, four differential gut microbiota (Incertae_Sedis, Anaerovorax, Anaerotruncus, and Helicobacter) between SHAM and OVX groups were found, whereas seven differential gut microbiota (Serratia, Anaerotruncus, Shewanella, Pseudomonas, Papillibacter, Exiguobacterium, and Helicobacter) between OVX and CUR groups were found. In conclusion, estrogen deficiency induced by ovariectomy caused changes in the distribution and structure of intestinal microflora in rats, and curcumin could partially reverse changes in the diversity of gut microbiota.

Published: October 2017

There is an increasing need for satellite-derived accurate chlorophyll-a concentration (chla) products to improve fisheries management in coastal regions. However, the methods used to derive these products have to be evaluated, so the associated uncertainties are known. The performance of three atmospheric correction methods, the near infrared (NIR), the shortwave infrared (SWIR), and the Management Unit of the North Seas Mathematical Models with an additional modification (MUMM + SWIR), and derived chla products based on the Moderate Resolution Imaging Spectroradiometer AQUA (MODIS) images acquired from 2002 to 2014 over the west coast of Canada and the United States were evaluated. The atmospherically corrected products and above-water reflectance were compared with in situ AERONET (N ~ 650) and above-water reflectance (N ~ 34) data, and the Ocean Color 3 MODIS (OC3M)-derived chla were compared with in situ chla measurements (N ~ 82). The statistical analysis indicated that the MUMM + SWIR method was the most appropriate for this region, with relatively good retrievals of the atmospheric products, improved retrieval of remote sensing reflectance with bias lower than 20% for the OC3M bands, and improved retrievals of chla (r = 0.83, slope = 0.89, logRMSE = 0.33 mg m−3 for ±1 h). The poorest chla retrievals were achieved with the SWIR and NIR methods. These results represent the most comprehensive satellite data analysis of MODIS retrievals for this region and provide a framework for the MUMM + SWIR method that can be further tested in other coastal regions of the world.
Modified Gray-Level Coding Method for Absolute Phase Retrieval

Published: October 2017

Fringe projection systems have been widely applied in three-dimensional (3D) shape measurements. One of the important issues is how to retrieve the absolute phase. This paper presents a modified gray-level coding method for absolute phase retrieval. Specifically, two groups of fringe patterns are projected onto the measured objects, including three phase-shift patterns for the wrapped phase, and three n-ary gray-level (nGL) patterns for the fringe order. Compared with the binary gray-level (bGL) method which just uses two intensity values, the nGL method can generate many more unique codewords with multiple intensity values. With assistance from the average intensity and modulation of phase-shift patterns, the intensities of nGL patterns are normalized to deal with ambient light and surface contrast. To reduce the codeword detection errors caused by camera/projector defocus, nGL patterns are designed as n-ary gray-code (nGC) patterns to ensure that at most, one code changes at each point. Experiments verify the robustness and effectiveness of the proposed method to measure isolated objects with complex surfaces.
A Research on Low Modulus Distributed Fiber Optical Sensor for Pavement Material Strain Monitoring
Authors: Meng Lingjian , Wang Linbing , Hou Yue , Yan Guannan
Published: October 2017

The accumulated irreversible deformation in pavement under repeated vehicle loadings will cause fatigue failure of asphalt concrete. It is necessary to monitor the mechanical response of pavement under load by using sensors. Previous studies have limitations in modulus accommodation between the sensor and asphalt pavement, and it is difficult to achieve the distributed monitoring goal. To solve these problems, a new type of low modulus distributed optical fiber sensor (DOFS) for asphalt pavement strain monitoring is fabricated. Laboratory experiments have proved the applicability and accuracy of the newly-designed sensor. This paper presents the results of the development.
Terahertz Spectroscopy for Proximal Soil Sensing: An Approach to Particle Size Analysis
Authors: Dworak Volker , Mahns Benjamin , Selbeck Jörn , Gebbers Robin , Weltzien Cornelia
Published: October 2017

Spatially resolved soil parameters are some of the most important pieces of information for precision agriculture. These parameters, especially the particle size distribution (texture), are costly to measure by conventional laboratory methods, and thus, in situ assessment has become the focus of a new discipline called proximal soil sensing. Terahertz (THz) radiation is a promising method for nondestructive in situ measurements. The THz frequency range from 258 gigahertz (GHz) to 350 GHz provides a good compromise between soil penetration and the interaction of the electromagnetic waves with soil compounds. In particular, soil physical parameters influence THz measurements. This paper presents investigations of the spectral transmission signals from samples of different particle size fractions relevant for soil characterization. The sample thickness ranged from 5 to 17 mm. The transmission of THz waves was affected by the main mineral particle fractions, sand, silt and clay. The resulting signal changes systematically according to particle sizes larger than half the wavelength. It can be concluded that THz spectroscopic measurements provide information about soil texture and penetrate samples with thicknesses in the cm range.
Making the Water–Soil–Waste Nexus Work: Framing the Boundaries of Resource Flows
Authors: Avellán Tamara , Roidt Mario , Emmer Adam , Von Koerber Janis , Schneider Petra , Raber Wolf
Published: October 2017

The Sustainable Development Goals have placed integrated resources management, such as integrated water resource management, at the heart of their targets. The upcoming “International Decade for Action—Water for Sustainable Development”, 2018–2028 has highlighted the importance of promoting efficient water usage at all levels, taking into account the water, food, energy, and environmental nexus. While integrated resource management approaches have been defined and applied for decades, nexus approaches are more recent. For these latter approaches to be implemented on the ground, their system boundaries need to be clarified. While the Water–Energy–Food Nexus focuses on sectors, the Water–Soil–Waste Nexus addresses linkages between environmental resources—namely water, soil and waste—to tackle sustainable management. In this paper, we analyzed integrated management systems and how their system boundaries are defined. From this we determined that in order for system boundaries to be applicable, they should be clear, wide and flexible. Based on this, we propose the boundary of the Water–Soil–Waste Nexus system. We use two case studies to exemplify the usefulness of these system boundaries.
Optimization of Drinking Water Distribution Systems in Relation to the Effects of Climate Change
Authors: Maiolo Mario , Mendicino Giuseppe , Pantusa Daniela , Senatore Alfonso
Published: October 2017

Proper water resources management involves the analysis and resolution of various optimization problems according to climate change effects on the availability and distribution of the resources themselves. Specifically, these conditions require the identification of new resource allocation optimization solutions capable of taking into account the water resource losses due to climate change scenarios. As is well known, Southern Italy is a region that is potentially very sensitive to climate change. In this paper, a 1717 km2 area, corresponding to the province of Crotone, was analyzed as a study case. This area is characterized by a sufficient availability of resources as a whole as compared to the needs of the users, but has an unbalanced distribution of water through its various systems. After identifying water resource allocations in detail for this area, an optimization solution accounting for the expected reduced availability of water resources in the context of climate change was created and was compared with the optimization solution for current water availability.
Melting Characteristics of Snow Cover on Tidewater Glaciers in Hornsund Fjord, Svalbard

Published: October 2017

In recent years, the Svalbard area, especially its southern section, has been characterised by an exceptionally thin snow cover, which has a significant impact of the annual mass balance of glaciers. The objective of this study was to determine melting processes of the snow cover deposited on 11 glaciers that terminate into Hornsund Fjord during the melting period of 2014. The study included analyses of snow pits and snow cores, meteorological data collected from automatic weather stations and Polish Polar Station Hornsund, and supervised classification of six Landsat 8 images for assessing the progress of snow cover melting. The calculated Snow-Covered Area (SCA) varied from 98% at the beginning of the melting season to 43% at the end of August. The melting vertical gradient on Hansbreen was −0.34 m 100 m−1, leading to surface melting of −1.4 cm water equivalent (w.e.) day−1 in the ablation zone (c. 200 m a.s.l. (above sea level)) and −0.7 cm w.e. day−1 in the accumulation zone (c. 400 m a.s.l.). Furthermore, the study identified several observed features such as low snow depth in the accumulation zone of the Hornsund glaciers, a large proportion of the snow layers (12–27%) produced by rain-on-snow events, and a frequent occurrence of summer thermal inversions (80% annually), indicating that the area is experiencing intensive climate changes.

Être et faire : se construire parents et enfants dans la migration
Authors: Moro Marie Rose
Published: October 2017

La culture de la parentalité est une grande affaire du XXI ème siècle, aussi bien sociétale que clinique. Nous examinerons ici la question du point de vue de la clinique transculturelle, qui associe de manière complémentariste l’anthropologie et la psychanalyse. Nous l’analyserons tout au long de la grossesse et de la mise en place des interactions précoces parents-enfants avec des séquences cliniques. Nous étudierons aussi les implications pour la seconde génération des enfants nés ici dans les familles migrantes, en particulier dans leur rapport au savoir et au monde extérieur. Nous montrerons l’importance du contre-transfert culturel intime et politique qui relègue l’autre à une position subalterne niant ses compétences, ses désirs et sa singularité.

Prendre sur moi
Authors: Hofstein Francis
Published: October 2017

Le surmoi de l’analyste ne sursoit à rien d’autre qu’à la nécessité de laisser celui de l’analysant le laisser chuter comme reste. C’est donc le risque de l’analyse que de buter sur l’analyste. Sa dissolution programmée passe, quand tout se passe au mieux, par une lente métamorphose de la place de l’autorité. En ce sens, la fin de l’analyse n’est pas dépourvue d’incidences quant au politique, qui peut s’en trouver quelque peu découronné. Mais la dimension asymptotique du processus n’a pas de quoi rendre inévitablement optimiste.
Le surmoi, l’analyste : troubles alliances
Authors: Salvadero Jérémie
Published: October 2017

Comment le surmoi est-il mis en jeu et en question dans une cure ? Lacan parle d’une alliance du surmoi et de l’analyste corrélée à la règle de l’asso­­ciation libre et ses implications. Le surmoi est à penser en son lien aux dimensions du père. Il s’agira d’interroger comment ce que nous pouvons appeler les deux faces du surmoi entrent en jeu dans la partie analytique : à la fois interdit et impératif de jouissance, le surmoi œuvre-t-il avec et contre le travail de la cure ? Nous faisons l’hypothèse qu’une cure passe par une désintrication des deux versants du surmoi, sa face d’objet pulsionnel, la voix, et sa face œdipienne ordonnant sa fonction à celle du père.
Y a-t-il un apport spécifique de la notion de « surmoi » en éthique ?
Authors: Cléro Jean-Pierre
Published: October 2017

Qu’est-ce qui fait que nous ne nous contentons pas d’être inscrits dans l’être par notre naissance, c’est-à-dire par nos parents, mais que nous ressentions comme un devoir de nous y inscrire, de nous y écrire, sans que nul ne puisse le faire à notre place ? Cette exigence d’écriture – que nous paraît être fondamentalement le surmoi – sera interrogée dans le prolongement des analyses lacaniennes qui, bifurquant par rapport aux analyses freudiennes, lesquelles rapprochaient ce qui se passe pour les hommes et ce qu’il en est des animaux supérieurs, mettent l’accent sur le langage et par conséquent sur la pluralité des langues. Ainsi, le problème du schématisme du surmoi (entre l’être et le devoir être ; entre les intérêts et la loi) nous paraît, sinon se résoudre par cet appel aux langues qui le diversifient de façon très étrange, mais du moins être mis par ce biais dans sa bonne direction.
Présentation de l’article de S. Freud. « Un cas d’atrophie musculaire avec troubles étendus de la sensibilité (syringomyélie) »

Dans la perspective de l’accès au titre de maître de conférence en neuro­­pathologie, Freud, en quelques années, poursuit à marche forcée sa formation personnelle dans les deux domaines d’élection de cette discipline, l’anatomie cérébrale et la neuropathologie. Il s’initie notamment pour ce faire à la pratique de l’électrodiagnostic en suivant les prescriptions de Wilhelm Erb, dont le manuel d’électrothérapie vient de paraître. C’est cet article qui le précédera dans sa rencontre avec Charcot près de deux ans plus tard grâce à l’intercession de son ami, le neurologue russe L. O. Darkschewitsch.

Freud, au cours des deux semestres de 1884 de son internat en médecine générale dans le service de Franz Scholz, construit un petit corpus de cas cliniques, en complément des travaux en neuroanatomie qu’il mène dans le laboratoire de Meynert et qu’il publie à la même époque. L’observation d’un cas d’atrophie musculaire est l’occasion de manifester sa maîtrise des techniques de pointe dans l’investigation de ces troubles et sa capacité diagnostique dans le domaine. C’est aussi l’occasion de participer au démembrement en cours d’une pathologie rare, la syringomyélie, qui témoigne de l’excellence de l’école de neurologie austro-allemande dans sa rivalité avec celle de la Salpêtrière.
Gender Fluidity in the Age of Technologically Mediated Environments
Authors: Hickman Mary-Kate , Ozuem Wilson , Okoya Jummy
Published: October 2017

Gender is a concept that has evolved with time, varying its meaning and relevance regularly. Today, it manifests across many facets of life. Whilst theories of gender began as a device to categorise individuals and groups, these have evolved into a broad, complex system of identification to describe the uniqueness of the individual. Central to the discussion of gender is the question of how we can understand human conduct and experience in technologically laden marketing environments. Drawing on extant theories, the current chapter examines how the technologically mediated marketing environment (TMME) is increasingly challenging fashion and luxury marketers to reconsider their marketing communications strategies, particularly with the impact of evolving Internet technologies such as social media platforms. The concluding section offers further agenda for future research.
The Lux Made in Case Study
Authors: Padua Donatella
Published: October 2017

The LMI Made-in-Italy (MiI) Jewelry business model which brings together the innovative concept of luxury Digital District (DD) and an e-commerce innovative platform is presented. The DD represents the shift from a traditional jewelry Industrial District of networked Micro-Enterprises (MEs), namely artisans, tied to the physical dimension of a territory to a social and intangible digital environment in the virtual space which leverages a co-petitive crowdsourcing e-commerce platform. The innovative LMI platform enables young Italian artisans throughout Italy to feature an end-to-end global export business without intermediaries. Export wouldn't be viable to MEs by means of their small organizational structure, lack of digital culture and technologies. LMI copes with this issue, taking over MEs marketing, sales and logistics processes by earning a percentage on sales. An original complex approach to the analysis of the LMI value proposition issues is performed via methodologies integrating traditional methods with participated Design Thinking techniques.

Drawing on social identity theory, the current chapter examines how the evolving social media platforms impact on brand perceptions in the fashion apparel and accessories industries. The chapter focuses on theoretical implications and managerial implications. The concluding section offers some significant roles that social media and social identity may play in keeping up with the design and development of marketing communications programmes.
Leveraging Knowledge Management for Value Creation in Service-Oriented Organisations of Namibia
Authors: Randa Isaac Okoth
Published: October 2017

Firms create value as a basis for their sustainability in two ways: physical transformation of inputs into high value outputs or arbitrage. This involves either cross-place arbitrage which is trade or cross-time arbitrage which is speculation. Modern economies driven by globalisation and fierce competition in which competitiveness is no longer determined by the possession of scarce capital and abundance of cheap labour but the utilisation of knowledge asset which improves with usage. In that context, knowledge-intensive services organisations stand to thrive and prosper testimony of the structural shifts in the sectoral contributions to GDP of many countries. Through conceptual analysis of documents, articles and reports, this paper suggests that emerging economies with abundant highly educated and skilled manpower coupled with natural resources endowment can leverage knowledge management as a core competency to catapult their services industry. This goal requires an understanding of critical success factors that drive successful organisational knowledge management strategies.
Proliferating View of Knowledge Management and Balanced Scorecard Outcome Linkage
Authors: Akgül Yakup , Tunca Mustafa Zihni
Published: October 2017

This chapter aims to develop the decomposed model to examine the impact of specific knowledge management resources (i.e., knowledge infrastructure capabilities and processes) on balanced scorecard outcomes (learning and growth, internal process, customer satisfaction, and financial performance). Prior research often utilizes composite models when examining the knowledge management-organizational performance link. But, understanding how individual resources relate to organizational performance remains gap. This study addresses this gap by assessing the links between specific knowledge management resources and organizational performance.
Tacit Knowledge Sharing and Value Creation in the Network Economy
Authors: Kucharska Wioleta
Published: October 2017

Key factors which affect competitive advantage in the network economy are innovation, relationships, cooperation, and knowledge. Sharing knowledge is not easy. Companies find it problematic. Presented studies show that the essence of the value creation today is not in sharing explicit but rather tacit knowledge, which is a source of creativity and innovation. Delivering value through knowledge does not only require efficient Transactive Memory Systems (TMS) but most of all a thorough approach to effective human interactions. Thus, to ensure tacit knowledge sharing, human resources management (HRM) needs to focus on the culture of collaboration, whose key element is trust among organization members. The aim of the chapter is to highlight that the network economy driven by knowledge workers as tacit knowledge producers caused the socially driven evolution of business.
Decoding Difference

Published: October 2017

Race, ethnicity, and gender issues have always been important matters in American politics. However, during the past two presidential elections these issues were the vanguard topics displayed on centerstage. The United Sates has a tainted history with respects to certain populations which it has discriminated against and marginalized throughout the country's history, and the tensions surrounding these issues erupted like a volcano. The United States became polarized as people began to align with different political and social ideologies depicting how those who are regarded as being different, “others”, should be treated. This chapter provides a brief history of marginalized populations in the United States and uses Critical Race Theory and self-awareness as means to help the reader understand the impact on society when racism and inequality are woven into the fabric of the country.

Authors: Houghton Robert F. , Parker Kevin R. , Davey Bill , Bozan Karoly
Published: October 2017

Collaborative work can provide a valuable learning experience, especially for those preparing to enter the information systems workforce. There have been numerous papers that discuss various effective means of realizing the benefits of collaborative group learning, but the approach still experiences issues stemming from pragmatic environmental factors such as the non-traditional nature of many students. This chapter has identified a range of problems and reports on a longitudinal Action Research study in two universities in Australia and the United States. Over three semesters problems were identified and methods tested using various approaches. Several promising remedies to the identified problems are suggested, including the use of student profiles, ePortfolios, project milestones, and freely available online collaborative tools.
Mobile Technology Integration and Student Learning Outcomes
Authors: Short Maureen N. , Uzochukwu Charity
Published: October 2017

Several schools leverage federal, state, local, and private funding to improve technology. Most have implemented their technology plans which range from providing each student with a digital device to equipping each classroom with an interactive white board or desktop computers. To fully realize the benefits of these technologies requires teachers to redesign their instructional strategies including participating in technology focused professional development and administrative support. This chapter examines the impact of technology integration on student learning outcomes and reviews a framework for the integration technology in the curriculum.
Learning All the Time and Everywhere
Authors: Thibodeaux Tilisa , Harapnuik Dwayne , Cummings Cindy , Wooten Rachelle
Published: October 2017

We are witnessing some of the most significant advancements of technology in most aspects of society, but our educational institutions are still mired in the industrial and information processing models of the nineteenth century. Why? We have used technology as a quick fix and ignored the fact that established organizations are dominated by nineteenth century organizational and management structures and cultures that prevent the effective adoption of twenty-first century technologies. In this chapter, we argue that we can break this cycle of wasteful implementation of educational technology by focusing on learning all the time and everywhere and by shifting our instructional practices away from the command and control teacher-centered perspective to the learner-centered perspective. This shift gives the learner choice, ownership, and voice through authentic learning opportunities that enables them to use technology to learn how to learn and adapt to the challenges of the future.
Understanding Teachers' Cultural Competencies
Authors: Dolzhenko Inna N. , Young Jemimah L.
Published: October 2017

As linguistic and cultural diversity in public schools continues to rise, an increased need for culturally aware teachers is warranted. This chapter informs the development of cultural competencies in teachers by integrating anti-bias education (ABE) goals into teacher preparation. Existing research in preparing teachers to work with diverse student populations tends to focus on how teachers gain appropriate knowledge and practices to work effectively at school. However, there is little evidence that researchers have approached the issue of developing teacher's cultural competencies with the intent of building a cohesive understanding and providing practical tools, such as ABE goals, to positively influence the development of social awareness and self-awareness in teachers and their students. Consequently, the aim of this chapter is to provide empirical evidence to substantiate the instructional importance of understanding the development of teacher's cultural competencies.
Meeting the Needs of Young English Language Learners
Authors: Estes Judi Simmons
Published: October 2017

From the fall of 2003 to the fall of 2013, the number of Hispanic students in K-12 schools increased from 19 percent to 25 percent; in addition, the percentage of English language learners (ELLs) in U.S. public schools was 9.4 percent during the 2014-2015 school year, ranging from 1.0 percent in West Virginia to 22.4 percent in California (NCES, 2016). General education teachers are increasingly likely to have ELL students in their classrooms, yet a majority of classroom teachers have little to no training in working with English language learners (NCES, 2011). This chapter provides a discussion of the role of language in learning, the needs of English language learners and their families, as well as the role of teacher preparation programs in preparing pre-service teachers to work with culturally and linguistically diverse young children.
Mi Familia

Published: October 2017

This chapter discusses the results of a writing activity during Family Literacy Night at a predominantly Hispanic, Title I school in the Southwest. This study, based on Socio-Cultural Theory (Moll, 2013), demonstrates the efficacy of asset-based approaches for instruction and assessment versus more traditional deficit models of minority education. As an analytic, the researchers applied the six Capitals from the Community Cultural Wealth (CCW) model (Yosso, 2005) to the children's writing samples. This framework revealed a variety of strengths common to Latino and bilingual households including the metalinguistic skill of translanguaging. Data was processed through Holistic Content Analysis (Lieblich, 2005) followed by thematic analysis (Falk & Blumenreich, 2005) supported by CCW. Results underscore the importance of out-of-school literacies and their affective impact on children from underserved communities. Moreover, results argue for more home- and community-based writing assignments to reveal student values, desires, and emotions, which encourage the joy of writing.
Examining Bilingual Teacher Candidates' Use of Digital Media

Published: October 2017

Digital media has transformed how we interact with each other, how we stay connected, and how we learn about the world around us. Digital media has also changed the teacher's role from knowledge provider to facilitator (Lee, 2006). Teachers however, continue to struggle with technology and curricula integration as a vehicle for engaging young learners with academics (Chen, 2010; Wachira & Keengwe, 2011). This chapter underscores the need to provide bilingual teacher candidates with specific instructional uses for digital media to increase their capacity with technology integration, pedagogy, and content knowledge (Mishra & Koehler, 2006). This chapter explores the use of digital media within an after-school technology project. This research lends additional support for teacher preparation programs to integrate the use of technology if they are to serve teachers who work with a growing culturally and linguistically diverse school-age population.

Nasal allergen challenge (NAC) is a human model of allergic rhinitis (AR) that delivers standardized allergens locally to the nasal mucosa allowing clinical symptoms and biospecimens such as peripheral blood to be collected. Although many studies have focused on local inflammatory sites, peripheral blood, an important mediator and a component of the systemic immune response, has not been well studied in the setting of AR. We sought to investigate immune gene signatures in peripheral blood collected after NAC under the setting of AR. Clinical symptoms and peripheral blood samples from AR subjects were collected during NAC. Fuzzy c-means clustering method was used to identify immune gene expression patterns in blood over time points (before NAC and 1, 2, and 6 h after NAC). We identified and validated seven clusters of differentially expressed immune genes after NAC onset. Clusters 2, 3, and 4 were associated with neutrophil and lymphocyte frequencies and neutrophil/lymphocyte ratio after the allergen challenge. The patterns of the clusters and immune cell frequencies were associated with the clinical symptoms of the AR subjects and were significantly different from healthy nonallergic subjects who had also undergone NAC. Our approach identified dynamic signatures of immune gene expression in blood as a systemic immune response associated with clinical symptoms after NAC. The immune gene signatures may allow cross-sectional investigation of the pathophysiology of AR and may also be useful as a potential objective measurement for diagnosis and treatment of AR combined with the NAC model.
Bing-Neel Syndrome: illustrative cases and comprehensive review of the literature

The Bing-Neel syndrome is a rare neurological complication of Waldenström’s Macroglobulinemia which results from a direct involvement of central nervous system by malignant lymphoplasmacytic cells. The clinical suspicion of Bing-Neel syndrome may be difficult because neurologic symptoms are heterogeneous, non specific and sometimes underhand. A definitive diagnosis of Bing-Neel syndrome can be confidently made using brain and spinal cord magnetic resonance imaging as well as histopathology and/or cerebrospinal fluid analysis to confirm the neoplastic infiltration of central nervous system. The detection in the cerebrospinal fluid of patients with Bing-Neel syndrome of the MYD88 (L265P) somatic mutation, which is highly recurrent in Waldenström’s Macroglobulinemia, revealed useful for the diagnosis and monitoring of central nervous system involvement. Despite recommendations recently published, there is still no clear consensus on treatment of Bing-Neel syndrome, which includes systemic immunochemotherapy, intrathecal chemotherapy and brain irradiation as possible options. Ibrutinib, a Bruton kinase inhibitor highly active in patients with Waldenström’s Macroglobulinemia, has been recently added to the therapeutic armamentarium of Bing-Neel syndrome due to its ability to pass the blood-brain barrier. However, prospective clinical trials are eagerly awaited with the aim to define the optimal treatment strategy. Here we describe four illustrative cases of Bing-Neel syndrome diagnosed and treated at our Institution and review the literature on this topic.

La preposición ἀπό en el griego del Nuevo Testamento. Algunos casos de controversia
Authors: Merino Hernández Marta
Published: October 2017

Una adecuada comprensión del signifi cado de las preposiciones en contexto es vital para la exégesis. En efecto, el debate exegético ha girado, en ocasiones, en torno al valor de una preposición en concreto. Sin embargo, siguen existiendo casos de desacuerdo en torno al sentido del morfolexema ἀπό en diferentes pasajes del NT, tanto en las traducciones y los principales diccionarios de griego clásico y neotestamentario como en algunas gramáticas y estudios. Este trabajo examinará pasajes del NT en los que el valor agentivo (de predicación pasiva) y el causal de ἀπό son erróneamente identifi cados entre sí o con otras funciones como las de separación, procedencia o intermediación. Tratará de dilucidar, por tanto, cuál es el ámbito signifi cativo de la preposición en cada caso siguiendo la metodología del Diccionario Griego-Español del Nuevo Testamento (DGENT), (Córdoba 2000-) de J. Mateos (†) - J. Peláez J. & GASCO, cuyo marco teórico seguiremos, así como dentro del eje o continuum conceptual que abarca las nociones de Causa y Agente e Intermediario. En defi nitiva, este artículo muestra cómo la aplicación del método de análisis semántico del DGENT, que supone nueva forma de tratar los lexemas, constituye un avance en el examen y la sistematización de los valores semánticos de la preposición ἀπό en el griego del corpus del NT, ya que permite analizar con precisión la preposición en contexto, arrojando luz sobre algunos pasajes neotestamentarios en los que su sentido ha sido largamente discutido por los investigadores.
La sombra del poder: Egisto
Authors: Bañuls Oller José Vicente
Published: October 2017

El poder, si es efectivo, proyecta una sombra, fenómeno inherente a su necesaria entidad, y en el caso del género de poder que representa Clitemnestra la sombra es de todo punto necesaria, pues su poder precisa de la existencia de Egisto, a la vez que de su no presencia. Intentaremos ahondar en las razones por las que se llega al estado de cosas presente en la Orestea de Esquilo.

Plutarco, dos "Vidas", tres oradores: Foción, Demóstenes y Démades
Authors: Alcalde Martín Carlos
Published: October 2017

En este artículo se analizan las fi guras de tres oradores, Foción, Demóstenes y Démades, en las biografías que Plutarco dedicó a los dos primeros. Intentamos demostrar que solo podemos aproximarnos a las ideas de Plutarco sobre su oratoria si establecemos la selección que hace de los datos procedentes de otros autores y los diferenciamos de las opiniones del biógrafo. Además, hemos contrastado estos datos con los que aparecen en otras fuentes históricas y literarias. De ese análisis complejo y detallado, situado en varios niveles, podemos extraer información muy útil para el estudio de la oratoria en las biografías de Plutarco, que a veces queda desdibujada o malinterpretada cuando se enfoca en un único personaje. Queda claro que Plutarco concede mayor importancia a la conducta y el carácter de los personajes y se basa en ellos para juzgar su oratoria, distanciándose así de las valoraciones que encuentra en sus fuentes.
Marianus Scholasticus’ APl 201. A Christian rewriting of Eros from Justin II and Sophia’s reign
Authors: A. Martins de Jesus Carlos
Published: October 2017

The aim of this paper is to perform a deep analysis of APl 201, a fi ve-couplet epigram ascribed in all manuscripts to the almost unknown Marianus Scholasticus. When describing a work of art also unidentifi able, the poet progressively transforms the Eros he (probably) sees in the image of the Christian saviour, by means of a cautious wordplay and a symbolic re-signifi cation of the pagan attributes of that god. Furthermore, some connections between Marianus’ other epigrams and the reign of Justin II and his wife Sophia’s, particularly the last one, come to suggest a commissioned relation of the poet with the imperial couple, in relation to an intentional advertising propaganda that aimed to promote both of them to icons of orthodoxy in the second half of the sixth century AD.
Circe y las sirenas de la épica griega al microrrelato hispanoamericano
Authors: Galindo Esparza Aurora
Published: October 2017

Este trabajo analiza la vigencia de las aventuras homéricas de Circe y las sirenas en el microrrelato hispanoamericano. Para ello, partimos de la épica griega arcaica para hacer un acercamiento a la tradición de estos temas odiseicos, tratando de detectar los principales hitos literarios que pueden haber infl uido de forma directa o indirecta en la narrativa ultrabreve posmoderna. A continuación, recogemos y comentamos una muestra de microrrelatos inspirados en los temas de Circe y las sirenas que nos permiten extraer unas conclusiones generales acerca de la pervivencia de estos motivos homéricos en la microfi cción americana contemporánea.
Reestructuración de las cajas de ahorros: evolución del número de oficinas 1986-2013
Authors: Bernad Morcate Cristina
Published: October 2017

En este trabajo se analiza el proceso de reestructuración experimentado por las cajas de ahorros españolas durante el periodo 1986 a 2013, a partir de la evolución en su red de oficinas. Con la liberalización que tuvieron a partir de 1989 y la posibilidad de expandirse sin restricciones, se produce un primer periodo de expansión y apertura de oficinas. La crisis económica y financiera, que ha afectado a todo el sector bancario, ha sido más intensa en las cajas de ahorros que se vieron inmersas en un proceso de fusiones, absorciones y a través de Sistemas Institucionales de protección (SIP) que tuvo como consecuencia, entre otras, el cierre de un elevado número de oficinas. Además, el trabajo realiza un análisis a fondo de cada entidad a nivel provincial, destacando el cálculo del índice de Herfindahl para conocer el grado de rivalidad en cada mercado. Finalmente se explica la situación del nuevo escenario tras el proceso de reestructuración.
