Aesthetic Dynamics, Inc. Presents: Afro-American Images 1971
Authors: Winslow Margaret 
Published: December 2019

Abstract
In February 1971, the artist collective Aesthetic Dynamics, Inc. presented its first major undertaking: an exhibition of over 130 works of art by 66 artists. Organized as a memorial to the late James A. Porter, Afro-American Images 1971 was presented at the National Guard Armory in Wilmington, Delaware. Many of the artists who participated in the show were well-established nationally; however, the location and inclusion of many artists known only to the local community resulted in the marginalization of this significant exhibition. In 2021, the Delaware Art Museum will restage the exhibition as a collaborative curatorial partnership with past and currents members of Aesthetic Dynamics, Inc. in an effort to counter this historical amnesia. Restaging as a curatorial methodology is a constructive means through which to aid in the recovery of the 1971 project, its archival record and its significance locally and nationally.
Restaging Origin, Restaging Difference: Restaging Harald Szeemann's Work
Authors: Foster Nicola 
Published: December 2019

Abstract
The most common form of restaging is that of the retrospective exhibition, for it can be used to provide a platform for the museum to reaffirm the original exhibition and in turn reaffirm itself as host. For Harald Szeemann, the role of the curator was that of a mediator who, through the exhibition, should attempt to halt the abovementioned closed-circuit of affirmations by questioning existing boundaries and canons. His own work, however, has been repeatedly restaged in recent years. This article focuses on two restagings: the Prada Foundation's When Attitudes Become Form: Bern 1969/Venice 2013 (2013) and the Getty Research Institute's Harald Szeemann: Museum of Obsessions (2018). I argue that restaged exhibitions can take two different forms: they can be focused on revising traditional canons and hierarchies, or they can serve to reaffirm the exhibition and the hosting institution. The two forms are interdependent, however, and most restagings contain a mixture of the two.
Dynamics of digital constituent outreach and engagement in linguistically divided societies: A quantitative look at the Canadian case
Authors: Richez Emmanuelle , Raynauld Vincent 
Published: December 2019

Abstract
This article unpacks how legislators in five Canadian provinces turn to official languages (French and English) for digital constituent outreach. In a linguistically fragmented society, use of languages is highly strategic as they can help spread information on political matters to the public and help legislators build support ahead of elections. This article first measures legislators' uses of bilingualism in the digital mediascape with the help of an index. It finds that legislators tend to be mostly unilingual in their digital constituent communications. Second, this article identifies factors influencing legislators' linguistic choices. It tests correlations between legislators' socio-demographic and political profile (e.g. gender, party affiliation, political rank) and uses of official languages. It also determines if the linguistic makeup of legislators' ridings impacts language choices. This article concludes that these variables may impact legislator's use of bilingualism depending on the province of origin and the type of online platform.

Obesity consistently associated with the development of a number of chronic diseases, leading to a decrease in quality of life, disability and death. The article examines the connection between obesity and disease of the musculoskeletal system, describes the mechanisms by means of which obesity leads to the development of osteoarthritis. It is evident that reduction of body mass can slow the progression of osteoporosis. The own experience of non-pharmacological and pharmacological treatment of obesity with the use of orlistat in 50 obese patients with osteoarthritis of the knee IIIII stage is presented. Treatment has resulted in a decrease in body weight, waist circumference, accompanied by a decrease in symptoms osteoarthritis among all the patients. Our results showed that the addition of orlistat to standard osteoarthritis scheme leads to significant reduction in weight and reduction of clinical manifestations of osteoarthritis. According to the above, the drugs that have impact on weight loss, should be included in the treatment regimen of patients with osteoarthritis and obesity.

Authors: Mosquera Hugo Edilberto Florido 
Published: December 2019

Em tempos de globalização vale a pena construir abordagens educacionais baseadas no direito de reconhecimento pleno da diversidade do ser humano nas formas de fazer, sentir, ser e ser no mundo. Por esse motivo é importante abordar a educação para a diversidade como uma educação para todos, sustentado no enfoque do direito, proporcionando à escola oportunidades razoáveis que atendam a diversidade e capacidades. Esses princípios tem como fundamento as sugestões do Programa das Nações Unidas para o Desenvolvimento (PNUD), afirmando em seu objetivo de desenvolvimento sustentável 4 (ODS4) que a educação será equitativa, inclusiva e de qualidade e promoverá oportunidades suficientes para todos, para que o aprendizado seja para a vida toda. Este artigo objetiva mostrar entre educação para a diversidade (educação para todos, equitativa, inclusiva e de qualidade) e sua relação com as capacidades humanas e as oportunidades que a escola deve oferecer para a conquista da aprendizagem ao longo da vida, em todas as comunidades, sem prejudicar sua contextualização e / ou condição.

Published: December 2019

We present the first records of fungi associated with feathers from seabirds and sea ducks in the Canadian Arctic and sub-Arctic. Birds sampled in Nunavut and Newfoundland (Canada) included the Common Eider (Somateria mollissima), King Eider (S. spectabilis), Black-legged Kittiwake (Rissa tridactyla), Northern Fulmar (Fulmarus glacialis), Glaucous Gull (Larus hyperboreus), Black Guillemot (Cepphus grylle), and Thick-billed Murre (Uria lomvia). In total 19 fungal species were cultured from feathers, identified using ITS rDNA barcoding, and screened for their ability to degrade keratin using a keratin azure assay. Our results indicate that 1) of the 19 isolates, 74% were ascomycetes, while the remaining 26% were basidiomycetes (yeasts); 2) 21% of the ascomycete isolates demonstrated keratinolytic activity (a known pathogenicity factor for fungi that may potentially be harmful to birds); 3) the largest number of fungi were cultured from the sampled Thick-billed Murre; and 4) based on a multiple correspondence analysis, there is some indication that both the King Eider and the Thick-billed Murre collected in the low Arctic had distinct fungal communities that were different from each other and from the other birds sampled. Although our sample sizes were small, initial trends in point (4) do demonstrate that additional study is merited to assess whether the fungal community differences are influenced by variation in the known ecologies of the avian hosts and fungi identified.
Co-management of Traditional Foods: Opportunities and Limitations for Food Security in Northern First Nation Communities

Published: December 2019

Traditional foods that First Nations peoples harvest or gather from the land remain critically important for achieving and sustaining food security for many communities. In Canada’s North, land claim agreements include provisions for First Nations to participate in the governance of their traditional territories, including the co-management of important traditional (wild-harvested) food species. Because such agreements only specify the broad contours of co-management governance, their actual functioning evolves out of a complex interplay among the co-managing organizations over the course of time. This paper aims to deepen our understanding of how First Nations communities can enhance food security as participants in co-management. Our study connects research on food security with research on co-management and is the first to analyze how First Nations can improve their food security by influencing decision-making that affects traditional foods through co-management arrangements. Following a succinct review of the Indigenous food security and co-management literatures, we analyze the experiences of Kluane First Nation in enhancing community food security through the co-management of its traditional territory with Yukon Government and Parks Canada, interpreting the data in light of the theories and evidences offered by research on co-management. The analysis of data collected from semi-structured interviews and from First Nations and government resources shows that, while the co-management system is imperfect, it does offer a mechanism through which First Nations can exert influence on decisions that affect their food security. The three key themes emerging from the excerpts confirm the importance of co-management as an evolutionary and long-term process, in which trust- and relationship-building are ongoing activities that are fundamental to beneficial collaboration involving the sharing of information and power. The analysis also highlights the role of context, or situational factors, in facilitating or hindering collaboration.
Archaeological Investigations at the Ikirahak Site Raise Questions Concerning Taltheilei Land Use in Southern Nunavut
Authors: Butler Don H. , Pickering Sean J. , Dawson Peter C. 
Published: December 2019

We report a new Taltheilei site-type found off the west coast of Hudson Bay in southern Nunavut. The Taltheilei is an archaeological culture that existed in the Barrenlands of the central Canadian Subarctic between 2600 and 300 years ago. Their land use strategies were tethered to the seasonal migrations of the Beverly and Qamanirjuaq caribou herds throughout tundra and forest landscapes. Tundra-based sites are typically interpreted as short-lived summer camps, but our discovery of three unique pit-house sites on the shores of Maguse Lake raises new questions concerning diversity in Taltheilei tundra land use. Architectural, faunal, lithic, and geoarchaeological data recovered from the Ikirahak site (JjKs-7) support the hypothesis that Taltheilei groups were extending their tundra stays into the fall. We report the evidence from four excavated pit-house features. Terraced platforms along the internal perimeters of these houses suggest they were designed for cold season use. The faunal assemblage is dominated by caribou remains. Higher relative frequencies of appendicular elements suggest a focus on secondary butchering. A large fraction of the faunal assemblage is highly fragmented and calcined, which is consistent with heavy processing and the use of bone as an alternative fuel source. Higher frequencies of lithic debris around dwelling floor perimeters are suggestive of maintenance activities. Multi-element concentrations in dwelling and site-wide sediments also show that hearth refuse was dumped outside. These findings seem to reflect longer tundra occupations during fall, a land use strategy that was likely guided by Qamanirjuaq herd behaviour specific to the Maguse Lake area, fall hunting and processing goals, and ecologically couched mobility logistics. As just four pit-houses from one Taltheilei camp have been investigated to date, our understanding of these places within Taltheilei worlds and northern socio-ecologies is currently limited. Further research at Ikirahak, the other Maguse Lake pit-house sites, and at other caribou water crossings on the tundra of the Qamanirjuaq caribou range is needed to support or refute our hypotheses.
Ramsey income taxation in a small open economy with trade in capital goods
Authors: Tang Jenn-Hong 
Published: December 2019

Abstract
In this paper, the optimal taxation problem in a small open economy with international trade in capital or investment goods is investigated. The monopolistic power of a small open economy over the terms of trade causes distortions in consumption and investment. The results suggest that due to the external distortion in investment, the long-run optimal capital income tax could be positive under the baseline calibration, and it is increasing in the degree of investment openness and decreasing in the elasticity of substitution between domestic and foreign goods. The long-run optimal labor income tax exhibits the opposite relationships with the openness and elasticity parameters. During the course of business cycles, the fluctuations in the external distortions cause the optimal labor income tax to be more volatile and the optimal capital income tax to be less volatile than their closed-economy counterparts.
Der Zwang zur Tragödie
Authors: Heller Jonas 
Published: December 2019

Abstract
The concept of the political in Carl Schmitt’s works is not only defined by the distinction between friend and enemy, but also by the criterion of breaching the rules in a normatively unbound act of decision. According to Schmitt, this decision is, however, not arbitrary, but provoked by the necessity of a historical situation. This aspect of necessity calls the freedom of the decision into question and leads to tensions within Schmitt’s theory of the political. More explicitly than in Schmitt’s political and legal writings, this conflict between freedom and necessity is exposed in his theory of tragedy. In a reading of his book Hamlet or Hecuba, published in 1956, I will show, in a first step, how the act of breaching the rules is not external to normativity, but occurs from within normativity itself. It is the act of self-breaching – of breaking the rules of its own genre – by which, according to Schmitt, modern tragedy is defined. This breach, however, is compelled by the necessity of a real, i. e. extraliterary, event. In a second step, I will expound on how this idea of self-breaching, which also characterises Schmitt’s understanding of the political, leads to a loss of decision which not only questions his idea of sovereignty, but also topples his concept of the political.
Peer victimization, depression, and sexual risk behaviors among high school youth in the United States: a gender-based approach
Authors: Kim Youn Kyoung , Yu Mansoo , Cronley Courtney , Yang Miyoun 
Published: December 2019

Abstract

Background and objectives
Little research has examined how different types of peer victimization (i.e. school bullying, cyber-bullying, and physical and sexual dating violence) predict sexual risk behaviors and how depression may mediate the relationship of such behaviors with types of peer victimization. Few works have investigated gender differences in these direct and indirect associations as well. This study, therefore, examined gender differences in the direct and indirect associations among four types of peer victimization, depression, and sexual risk behaviors in United States (US) high school students.

Materials and methods
Data were drawn from the 2015 Youth Risk Behavior System Survey, collected by the U.S. Centers for Disease Control and Prevention. A multigroup path analysis was conducted using a national sample of high school students who reported having ever engaged in sexual intercourse (n = 5,288).

Results
All the peer victimization variables positively predicted depressive symptoms for both females and males. The direct effects of physical and sexual dating violence were associated with increased sexual risk behaviors for females and males. However, school-bullying victimization did not significantly predict sexual risk behaviors for either gender. Cyber-bullying victimization significantly predicted increased sexual risk behaviors for males only. Among indirect effects, depression positively mediated the relationship between cyber-bullying victimization and sexual risk behaviors for males only.

Conclusions
Our findings suggest that male adolescents who are victimized may actually be at higher risk of negative outcomes compared to their female adolescent peers. This study highlights the need to pay attention to male victims who may be ashamed to self-identify and difficult to detect in cyber-bullying.

Abstract
The solar power is one of the most promising renewable energy resources, but the high cost and complicated preparation technology of solar cells become the bottleneck of the wide application in many fields. The most important parameter for solar cells is the conversion efficiency, while at the same time more efficient preparation technologies and flexible structures should also be taken under significant consideration [1]. Especially with the rapid development of wearable devices, people are looking forward to the applications of solar cell technology in various areas of life. In this article the flexible solar cells, which have gained increasing attention in the field of flexibility in recent years, are introduced. The latest progress in flexible solar cells materials and manufacturing technologies is overviewed. The advantages and disadvantages of different manufacturing processes are systematically discussed.
Preparation of low-permittivity K2O–B2O3–SiO2–Al2O3 composites without the addition of glass

AbstractIn the field of low temperature co-fired ceramic (LTCC), it remains a challenge to design the performance of LTCC with low permittivity less than 5. Here, the K2O– B2O3–SiO2–Al2O3composites are prepared without the preparation of prior glass. Meanwhile, the factors of the CaO content on microstructure, phase structure and properties of the composites are considered systematically. The crystal structure measured by X-ray diffraction (XRD) shows that there are quartz and alumina as the crystal phases. The results reveals that the tailoring CaO content benefits sintering densification, low dielectric loss, great mechanical properties and low thermal expansion coefficient. As CaO content increases up to 2.8 wt%, the composites sintered at 850∘C have a dielectric constant of 4.94 and tanδof 8 × 10−4at 1 MHz, thermal expansion coefficient (CTE) of 8.5 ppm/∘C, and flexural strength of 150 MPa. As the mass fraction of CaO increases up to 3.2 wt%, the maximum flexural strength of 173MPa is achieved. The above study provides an effective approach for preparing the novel composites as a promising candidate for LTCC applications.
Outliers and misleading leverage effect in asymmetric GARCH-type models
Authors: Carnero M. Angeles , Pérez Ana 
Published: December 2019

Abstract
This paper illustrates how outliers can affect both the estimation and testing of leverage effect by focusing on the TGARCH model. Three estimation methods are compared through Monte Carlo experiments: Gaussian Quasi-Maximum Likelihood, Quasi-Maximum Likelihood based on the Student-t likelihood and Least Absolute Deviation method. The empirical behavior of the t-ratio and the Likelihood Ratio tests for the significance of the leverage parameter is also analyzed. Our results put forward the unreliability of Gaussian Quasi-Maximum Likelihood methods in the presence of outliers. In particular, we show that one isolated outlier could hide true leverage effect whereas two consecutive outliers bias the estimated leverage coefficient in a direction that crucially depends on the sign of the first outlier and could lead to wrongly reject the null of no leverage effect or to estimate asymmetries of the wrong sign. By contrast, we highlight the good performance of the robust estimators in the presence of one isolated outlier. However, when there are patches of outliers, our findings suggest that the sizes and powers of the tests as well as the estimated parameters based on robust methods may still be distorted in some cases. We illustrate these results with two series of daily returns.
