Art Viewing Directives in Hospital Settings Effect on Mood
Authors: Ho Rainbow T. H. , Potash Jordan S. , Fang Fan , Rollins Judy 
Published: April 2015

Objective: The purpose of this study was to determine the effect viewing directives can have when encountering art in hospitals. A secondary objective of the study was to understand the responses of viewers to an art exhibit on the theme of medical student empathy toward patient pain and suffering. Background: Displaying art in hospitals has been credited with increasing well-being of patients, visitors, and staff. Generally, hospital curators have focused on the type of art to display (natural, symbolic, and abstract). This focus has neglected the possibility that in addition to the type of art, the way that viewers engage art may also be responsible for the healing effect. Methods: Participants (n = 97) were randomly allocated into one of the viewing directives: (1) reflecting on one artwork, (2) creating a drawing or poem in response to one artwork, or (3) no direction. Prior to looking at the art and immediately after, participants were administered the Brief Mood Introspection Scale (BMIS) and offered an opportunity to participate in an interview. Results: Pre–post results of the BMIS demonstrated that viewers who received directions achieved some therapeutic effect. Qualitative themes from the post-exhibit interviews identified that the empathy themed exhibit was well received, although there were differences among responses from patients, visitors, and staff. Conclusions: The results imply that hospitals may consider offering prompts to help viewers engage with art to enhance mood and exhibiting art that demonstrates empathy for patient suffering.

AbstractThe reduced graphene oxide (RGO)/carbon double-coated 3-D porous ZnO aggregates (RGO/C/ZnO) have been successfully synthesized as anode materials for Li-ion batteries with excellent cyclability and rate capability. The mesoporous ZnO aggregates prepared by a simple solvothermal method are sequentially modified through distinct carbon-based double coating. These novel architectures take unique advantages of mesopores acting as space to accommodate volume expansion during cycling, while the conformal carbon layer on each nanoparticle buffering volume changes, and conductive RGO sheets connect the aggregates to each other. Consequently, the RGO/C/ZnO exhibits superior electrochemical performance, including remarkably prolonged cycle life and excellent rate capability. Such improved performance of RGO/C/ZnO may be attributed to synergistic effects of both the 3-D porous nanostructures and RGO/C double coating.

Abstract
Introduction
Breast cancer progression is promoted by stromal cells that populate the tumors, including cancer-associated fibroblasts (CAFs) and mesenchymal stem/stromal cells (MSCs). The activities of CAFs and MSCs in breast cancer are integrated within an intimate inflammatory tumor microenvironment (TME) that includes high levels of tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β). Here, we identified the impact of TNF-α and IL-1β on the inflammatory phenotype of CAFs and MSCs by determining the expression of inflammatory chemokines that are well-characterized as pro-tumorigenic in breast cancer: CCL2 (MCP-1), CXCL8 (IL-8) and CCL5 (RANTES).

Methods
Chemokine expression was determined in breast cancer patient-derived CAFs by ELISA and in patient biopsies by immunohistochemistry. Chemokine levels were determined by ELISA in (1) human bone marrow-derived MSCs stimulated by tumor conditioned media (Tumor CM) of breast tumor cells (MDA-MB-231 and MCF-7) at the end of MSC-to-CAF-conversion process; (2) Tumor CM-derived CAFs, patient CAFs and MSCs stimulated by TNF-α (and IL-1β). The roles of AP-1 and NF-κB in chemokine secretion were analyzed by Western blotting and by siRNAs to c-Jun and p65, respectively. Migration of monocytic cells was determined in modified Boyden chambers.

Results
TNF-α (and IL-1β) induced the release of CCL2, CXCL8 and CCL5 by MSCs and CAFs generated by prolonged stimulation of MSCs with Tumor CM of MDA-MB-231 and MCF-7 cells. Patient-derived CAFs expressed CCL2 and CXCL8, and secreted CCL5 following TNF-α (and IL-1β) stimulation. CCL2 was expressed in CAFs residing in proximity to breast tumor cells in biopsies of patients diagnosed with invasive ductal carcinoma. CCL2 release by TNF-α-stimulated MSCs was mediated by TNF-RI and TNF-RII, through the NF-κB but not via the AP-1 pathway. Exposure of MSCs to TNF-α led to potent CCL2-induced migration of monocytic cells, a process that may yield pro-cancerous myeloid infiltrates in breast tumors.

Conclusions
Our novel results emphasize the important roles of inflammation-stroma interactions in breast cancer, and suggest that NF-κB may be a potential target for inhibition in tumor-adjacent stromal cells, enabling improved tumor control in inflammation-driven malignancies.
Cellular models and therapies for age-related macular degeneration
Authors: Forest David L. , Johnson Lincoln V. , Clegg Dennis O. 
Published: April 2015

ABSTRACT
Age-related macular degeneration (AMD) is a complex neurodegenerative visual disorder that causes profound physical and psychosocial effects. Visual impairment in AMD is caused by the loss of retinal pigmented epithelium (RPE) cells and the light-sensitive photoreceptor cells that they support. There is currently no effective treatment for the most common form of this disease (dry AMD). A new approach to treating AMD involves the transplantation of RPE cells derived from either human embryonic or induced pluripotent stem cells. Multiple clinical trials are being initiated using a variety of cell therapies. Although many animal models are available for AMD research, most do not recapitulate all aspects of the disease, hampering progress. However, the use of cultured RPE cells in AMD research is well established and, indeed, some of the more recently described RPE-based models show promise for investigating the molecular mechanisms of AMD and for screening drug candidates. Here, we discuss innovative cell-culture models of AMD and emerging stem-cell-based therapies for the treatment of this vision-robbing disease.
The Economics of Nationalism
Authors: Lan Xiaohuan , Li Ben G. 
Published: April 2015

This paper provides an economic framework for examining how economic openness affects nationalism. Within a country, a region's level of nationalism varies according to its economic interests in its domestic market relative to its foreign market. All else being equal, increasing a region's foreign trade reduces its economic interests in its domestic market and thus weakens its nationalism. This prediction holds both cross-sectionally and over time, as evidenced by our empirical study using the Chinese Political Compass data and the World Value Surveys. Our framework also applies to analysis of nationalism across countries and receives support from cross-country data. (JEL F14, F52, O17, O19, P26, P33) It is not easy to see how the more extreme forms of nationalism can long survive when men have seen the Earth in its true perspective as a single small globe against the stars. — Arthur C. Clarke, 1951

Published: April 2015

Abstract
This study examined the validity of the Social Communication Questionnaire (SCQ) to identify autism spectrum disorder (ASD) in 151 adults with intellectual disabilities (ID) in Germany. Sensitivities and specificities for ASD were 98/47% for the SCQ-current version and 92/22% for the SCQ-lifetime version. Sensitivities and specificities were increased to 89/66% and 78/48% by adjusting the recommended cut-points. The SCQ-current score correlated with the Scale for Pervasive Developmental Disorders in Mentally Retarded Persons and the Autism Diagnostic Observation Schedule, whereas the SCQ-lifetime score correlated with the Autism Diagnostic Interview-Revised. Our findings support the use of the SCQ-current version for ASD screening in adults with ID, although the SCQ-lifetime version should be used with caution in this population.
Employing mindfulness via art in education
Authors: Patterson Jodi 
Published: April 2015

Abstract
Visual art is often misunderstood and under-applied in a venue where it has the potential to help humans the most: the general elementary classroom. Teacher training programmes that mandate an art class can help propel art’s offering by exposing future teachers to the increasing role mindfulness via art can play in school regarding cognitive, social and emotional well-being. This article cites ways and means to incorporate mindful art experiences into the classroom to help enhance both teaching and learning.
A cross-cultural collaboration exploring art literacy, creativity and social transformation in China
Authors: Silverman Jonathan , Xiaoming Yi 
Published: April 2015

Abstract
Two art educators, from the United States and China, reflect on their collaboration to plan, implement and assess a cross-cultural experience. They developed a ten-day residency for art education students at Nanjing Normal University in China. The pedagogy presented emphasized the interplay between skill development and personal expression, product and process, and social-directed knowledge and social transformation. Through analysing student critiques, reflective discussions and survey responses the authors framed five categories critical for planning cross-cultural exchanges and broadening the scope of art education: Sensing others’ cultural orientation, Building community, Scaffolding art literacy, Minding the gap between technique and creativity, and Reflecting on identity and visual culture. In a global society, culturally responsive art educators benefit when collaborating to help their students gain new perspectives on cultural assumptions, analyse common concepts such as aesthetics, visual literacy and critique, and reflect on the interdependence of teaching, creating art and social responsibility.
来自美国和中国的两位艺术教育者反思和评价了他们合作研究的计划、实施以及跨文化的体验。他们在中国南京师范大学开展了十天面向艺术教育专业学生的教学。整个教学强调技能发展和个人表达、结果与过程、社会导向的知识与社会变革之间的相互作用。通过分析学生的评论、反思性讨论以及对调查问题的回答，作者提出了五个开展跨文化交流和扩展艺术教育视野的关键性问题，即体验他国文化；建立共同体；构架艺术素养；关注技能和创造力之间的落差；反思身份意识和视觉文化。在一个全球化的社会，当合作有助于学生获得看待文化假设的新视角，分析诸如审美、视觉素养等共同的概念，评论和反思教学、艺术创作和社会责任之间的相互依存关系时，那么具有文化应对意识的艺术教育者将能从中获益。
Coming to Terms with Horror
Authors: Festić Fatima 
Published: April 2015

Abstract
The paper discusses the possibilities of building a framework for conceptualization and understanding of the effects of the atrocities committed upon the collapse of ‘ex-Yugoslavia’. It relates the war-horrors and personal and collective traumas to the everyday of the people(s) of both the communist and post-communist times, and includes empirical cross-references from the social relations, cultural, educational and political contexts while revealing the ambivalent meanings of the ‘ghosts of the past’ and of their ‘return’. In rethinking the notions of the signifier, representation, the abject from the social/the symbolic, the text argues for the centrality of memory work based on victims’ experiences and their articulation in public spaces in the post-war societies. Envisioning the move forward and safer inter-ethnic relations on the discussed territories argues for individual responsibility in the processes of (re)construction and (re)formation of complex personal, collective and national identities, lived memory and institutions and in attempts to inter- and intracommunicate the particularized units.
Semiotic Confusion in the Phenomenology of Perception
Authors: Lanigan Richard L. 
Published: April 2015

Abstract
The communication analysis presented in the article compares the semiotic coding of visual perception in cultural theory and practice. The USA is used as an example of Western Culturology (egocentric, isometric) compared to the PRC as an example of Eastern Culturology (sociocentric, axonometric). Perception is explicated within the general context of Discourse Expression (rhetoric, aesthetics) and illustrated using examples from the visual arts, notably painting, a television image, and flower arrangement. Because contemporary popular media image production emerged from Japan, Chinese and Japanese art examples are also considered. The primary purpose of the general analysis is pedagogical, to teach semiotic phenomenological methodology in communicological and culturological research.
Obesogenic environments: environmental approaches to obesity prevention
Authors: Lipek Tobias , Igel Ulrike , Gausche Ruth , Kiess Wieland , Grande Gesine 
Published: April 2015

AbstractChildhood obesity is a major concern for public health. There are multiple factors (e.g., genetic, social, and environmental) that contribute to unhealthy weight gain. Drawing from findings on “obesogenic environments” and core principles of preventive strategies to reduce health inequalities, this paper gives an overview of recent childhood prevention programs that target aspects of the physical environment (“environmental changes”). Out of the ten reviews we screened (including more than 300 studies), we identified very few that addressed aspects of the environment. We focus here on 14 programs that follow different approaches to environmental changes (e.g., access to/quality of playgrounds, changes in school cafeterias). Altering the environment offers opportunities for healthier behaviors and seems to be an effective strategy to prevent childhood obesity. However, the evaluation of those (mostly) multidimensional interventions does not allow drawing firm conclusions about the single effect of environmental changes. We conclude that obesity prevention programs should combine person-based and environmental approaches.

Published: April 2015

Background & Aims. Carbon-based nanomaterials such as carbon nanotubes, graphene oxide and graphene have been explored by researchers as well as the industry. Graphene is a new nanomaterial which has commercial and scientific advantages. Laser therapy has proven highly useful in biomedicine, with the use of different laser types and energies for distinct purposes. The low level laser therapy (LLLT) can have anti-inflammatory, analgesic and biostimulant effects. Recent research has shown that laser radiation has different effects on osteoblasts. The aim of this study was to identify the influence of laser radiation on human osteoblastic cells cultured on nanostructured composite substrates.Materials and methods. Four types of substrates were created using colloidal suspensions of nanostructured composites in PBS at a concentration of 30 µg/ml. We used human osteoblasts isolated from patella bone pieces harvested during arthroplasty. Irradiation of osteoblasts cultured on nanostructured composite substrates was made with a semiconductor laser model BTL-10 having a wavelength of 830 nm. The proliferation activity of osteoblast cells was assessed using the MTT assay. After laser irradiation procedure the viability and proliferation of osteoblast cells were analyzed using fluorescein diacetate (FDA) staining. Results. The osteoblast cells viability and proliferation were evaluated with MTT assay at 30 minutes, 24 hours, 5 days and 10 days after laser irradiation. In the first 30 minutes there were no significant differences between the irradiated and non-irradiated cells. At 24 hours after laser irradiation procedure a significant increase of MTT values in case of irradiated osteoblasts cultivated on nanostructured hydroxyapatite, nanostructured hydroxyapatite with gold nanoparticles and 1.6% and 3.15% graphenes composites substrates was observed. A more marked proliferation rate was observed after 10 days of irradiation for irradiated osteoblasts seeded on nanostructured hydroxyapatite with gold nanoparticles and graphenes containing substrate. Using FDA staining we obtained very similar results with MTT test. Conclusions. The association between the 830 nm laser irradiation of osteoblasts and their long-term cultivation of the nanostructured composite substrates induces the cell proliferation and differentiation and, therefore, it will be a useful alternative for bone regeneration therapy.

Published: April 2015

The knowledge about the distribution of Ephemeroptera in Brazil has increased in recent years, contributing to reduce the gaps about its distribution in this country. This paper presents an updated checklist of the species of Ephemeroptera from Pernambuco state, Northeastern Brazil based on bibliography and collections from numerous rivers and streams of 27 counties and 74 localities. In this study, 18 species and 11 genera are recorded for the first time from Pernambuco state, increasing from 43 to 61 the number of known species. With these results, Pernambuco becomes the state with highest number of species in Northeastern Region of Brazil. Moreover, Caenis chamie is reported for the first time from Brazil.
Theoretical and experimental investigation of the recombination reduction at surface and grain boundaries in Cu(In,Ga)Se2 solar cells by valence band control
Authors: Nishimura Takahito , Hirai Yoshiaki , Kurokawa Yasuyoshi , Yamada Akira 
Published: April 2015

ABSTRACTWe carried out theoretical calculation for Cu(In,Ga)Se2 (CIGS) solar cells with energy bandgap of 1.4 eV assuming formation of a Cu-poor layer on the surface of CIGS films. This calculation result revealed that formation of a thinner Cu-poor layer such as a few nanometers leads to improvement of the solar cells performance. This is because interfacial recombination was suppressed due to repelling holes from the interface by valence band offset (ΔEV). Next, we investigated composition distribution in the cross section of CIGS solar cells with Ga contents of 30% and 70% by transmission electron microscopy (TEM) and energy dispersive X-ray analysis (EDX). It was revealed that the Cu-poor layer was formed on the surface and at the grain boundary (GB) in the case of conversion efficiency (η) of 17.3%, although it was not formed in the case of lower η of 13.8% for a Ga content of 30%. These results indicate that formation of the Cu-poor layer contributed to improvement of cell performance by suppression of carrier recombination. Moreover, it was also confirmed that although the Cu-poor layer was observed on the surface, it was not observed at the GB in the case of CIGS solar cells with a Ga content of 70% which had η of 12.7%. It is thought that the effect of repelling holes by ΔEV is not obtained at the GB and the solar cell performance in the Ga content of 70% is lower than that in the Ga content of 30%. Thus, we suggest importance of the Cu-poor layer at the GB for high efficiency of CIGS solar cells with high Ga contents.
The Vanuxem Collection
Authors: Kemmerly Phillip 
Published: April 2015

The Lardner Vanuxem collection of minerals and fossils, lost since its sale in 1853-1854 to W. M. Stewart of Clarksville, Tennessee, has been rediscovered, along with a catalog of the collection. The collection is summarized in tabular form. The disposition of the specimens since the death of Vanuxem, in 1848, is also discussed.
About five percent of the original 6,000-specimen mineral collection still exists at Southwestern University at Memphis. The Vanuxem collection catalog, reprinted by W. M. Stewart circa 1855, indicated a comprehensive collection of the minerals known in the first half of the 19th century.
The Vanuxem fossil collection contained some 16,000 sepcimens, most of which were from the Lower Paleozoic (Potsdam Sandstone, Medina Sandstone, Marcellus Shale, and many Trentonianage formations) of New York State. The collection was organized later by W. M. Stewart on the basis of geologic periods. Ordovician, Silurian, Devonian, and Tertiary fossils are dominant. No trace of the Vanuxem fossil collection exists today, although it was still in use in 1923 by students at Southwestern Presbyterian University, Clarksville, Tennessee.
