Scenarios of Health Engagement Experiences and Health Justice in Rural Libraries
Authors: Mehra Bharat , Sikes Everette Scott , Singh Vandana
Published: August 2019

This article documents scenarios or narratives of health engagement experiences in rural libraries based on qualitative analysis of feedback collected from 15 rural librarians in the Southern and Central Appalachian (SCA) region during semi-structured interviews conducted in 2017-2018. The article focuses on respondents’ perspectives of the “aboutness” of their health-related engagement, collaborating partners, encountered challenges, and resulting outcomes. Scenarios were documented in broader interviews that focused on specific health activities and community engagement in 11 domains, including agriculture, diversity, economy, education, environment, government, health, law, manufacturing, social welfare, and other. The research forms part of a planning grant entitled “Assessment of Rural Library Professionals’ Role in Community Engagement in the Southern and Central Appalachian Region: Mobilization from Change Agents to Community Anchors (CA2CA@SCA-RL)” awarded by the Institute of Museum and Library Services to the University of Tennessee, sub-contracted to the University of Alabama this year (July 2017 – June 2019). Scenarios provide a taxonomic classification of health-related programs relevant to the region and a framework of practice related to their implementation. As a health justice tool, they also challenge the hegemonic imagination of mainstream American society, news media, and popular culture that has only presented the SCA rural belt in deficit light. The article becomes a counter-point to these past unfair and marginalizing representations in its constructive asset recognition of the SCA rural librarians’ positive examples of health-related experiences. It spotlights the “invisible” of SCA librarians’ individual/community empowerment as change agents making an impact on the lives of their rural residents.
Same Tricks, New Name: The IAAF’s New 2018 Testosterone Regulation Policy for Female Athletes
Authors: Posbergh Anna
Published: August 2019

On April 26, 2018, the International Association of Athletics Federations (IAAF) released its updated version of its policy on athletes with hyperandrogenism, in a discriminatory attempt to define the term female through specified levels of testosterone, and to thereby provide asolution to the problem of athletes who fell outside of their socially constructed gender binary. The IAAF’s attempts to uphold this outdated binary system is a reflection of normalized scientific discourse which creates accepted, supposedly normal, behaviors and bodies at the expense of and resulting in the oppression of those who challenge these dominant regimes of knowledge (Foucault, 1978). Certainly, the prioritization of scientific knowledge is nothing new for the intersex community, given the history of irreversible genital surgery on newborns and young children with genitalia that is incongruent with current sex standards to make them fit societal gender ideals (Davis, 2015; Karkazis, 2008). In this paper, I trouble the IAAF’s supposed solution to intersex athletes through a Foucauldian understanding of biopower and science-based constructions of knowledge and truths, with particular attention to the perpetuation of health disparities within the intersex community. More specifically, I examine the site and role of female athletes’ bodies, such as Caster Semenya, whose rights to equitable and just treatment were cast aside in order to uphold artificially constructed and societally accepted ideas of male and female. I use Semenya’s narrative, coupled with the scientific discourse in the IAAF’s decision, to explore the subsequent, but unsurprisingly repetitive, reproduction of the hierarchical power relations between governing sports bodies and athletes, especially female athletes.
Creating a Culture of Equity: Building Awareness Within the Montgomery County Department of Health and Human Services
Authors: Sardana Surbhi
Published: August 2019

The Robert Wood Johnson Foundation recognizes Montgomery County as the county with the best health outcomes, length of life, and quality of life in all of Maryland. While impressive, the overall statistics do not reflect the disparities among certain population groups in the county. As a major provider of safety net health and social services to county residents, the Montgomery County Department of Health and Human Services (MCDHHS) wants to empower staff to think and act differently to generate better outcomes for disadvantaged communities. Among the many phases toward building an equity value driven organization, the Department felt that cultivating a common understanding and buy-in from all levels of staff is critical to a cultural shift. In 2014, a comprehensive workshop was implemented to raise awareness and encourage courageous conversations. The workshop seeks to create a common understanding of equity, its principles and applied strategies, and provide Department staff with the tools to treat their colleagues, customers, and clients more equitably. To date, 828 staff, contractors, and community partners have completed the workshop and 47 staff members have trained as workshop peer facilitators. This paper will explore in more detail the information-related factors and processes present in the workshop and their equity impact on the Department’s practices.
Didactic Modelling for Socio-Ecojustice
Authors: Sjöström Jesper
Published: August 2019

In northern Europe and Scandinavia, there is a tradition called Didaktik. It can be seen as both the art of teaching and as the “science for teachers”, helping us teachers answering didactic questions about WHY?, WHAT? and HOW? to teach (and support learning). Many areas of subject-specific Didaktik have in recent decades evolved from mainly practice-based methodology to quite independent research areas. This applies, for example, to the field of science-Didaktik (i.e., Science Education). Part of this field has a special interest in educational activities for socio-ecojustice. For instance, it can include complex issues used in teaching to build bridges across different curriculum subjects, among them STEM-subjects, in support of sustainability, reflexive Bildung and socio-political activism. The focus in this paper is on socalled didactic models and modelling aiming at actions for socio-ecojustice. In particular, the paper presents a model for eco-reflexive Didaktik, an example of a didactic model. Didactic modelling is the name for the processes when didactic models are used and developed, often by researchers in collaboration with practitioners. The didactic model in focus here is based on philosophical ideas and orientations, such as holism, critical realism, egalitarianism, altruism, reconstructionism and critical pedagogy.

ECOLOGICAL ASPECTS OF POLLINOSIS. LITERATURE REVIEW
Authors: Shiriaeva D M , Minaeva N V , Novoselova L V
Published: August 2019

The review is dedicated to the analysis of ecological aspects of pollen allergy (pollinosis). The characteristic of pollen as a natural aerosol component is given. The information related to aeropalinological monitoring and its importance in public health service is presented. The peculiarity of this pathology is its regional variety associated with differences in plant species compositions and pollen periods. The problem of immune response formation to pollen has been studied most profoundly. At that it is known that sensibilization is not always associated with clinical signs. Russian and foreign data about correlation studies between the pollen quantity and the disorder symptom load are discussed. It is shown that there is no decisive answer to the question about threshold pollen counts of certain plants and its impact on different stages of respiratory diseases. The detailed analysis of the correlation between the symptoms and quantitative variables of pollen allergens may provide useful information for risks evaluation of disease exacerbation as well as for tactics elaboration of hypoallergic measures. This is a cross-disciplinary issue involving allergology, aerobiology and ecology. The perspective of further development of this subject in order to obtain more accurate vision of the reasons, mechanisms and patterns of all parts of multifactorial process of pollinosis formation is discussed.

Authors: Lubyako E A , Korchina T Ya
Published: August 2019

The aim of the study was to reveal peculiarities of immune reactivity in adults nonresidents of Khanty-Mansiysk (Khanty-Mansiysk Autonomous Area) suffering from metabolic syndrome. 126 adult nonresidents of the city were surveyed: 72 patients with a metabolic syndrome (MS) and 54 without MS (control group). Average age of surveyed was 40,5 ± 4,2 years old. Indices of humoral and cellular components of immune system were revealed. As a result, patients with MS had statistically significant excess of indices both humoral (circulating immune complexes large, С-reactive protein - р < 0,001, complement component C4 - р = 0,002) and cellular (suppressor cell, T-NK lymphocytes - р < 0,001) components of immune system in comparison with the control group. Excess of suppressor cell (88,9 % patients with MS, 72,2 % without MS) and T-NK lymphocytes (54,2 % patients with MS, 24,1 % without MS) concentration was revealed in large majority of the surveyed. As can be seen from above changes were registered in humoral and cellular components of immune system of surveyed persons which indicated tension of the immune system functioning in conditions of the Northern region.
Review of Socio-Demographic and Economic Predictors of Adolescent Pregnancies in Rural Ghana
Authors: Naziru Mohammed Tanko , Gbagbo Fred Yao , Agbeno Evans Kofi , Otupiri Easmon
Published: August 2019

Introduction: Ghana developed her adolescent reproductive health policy in october 2000 to guide implementation of adolescent reproductive
health and related services. Despite a comprehensive policy implementation strategy, the burden of adolescent pregnancies in rural Ghana
remains a public health challenge since little is known about the core predictors. This study therefore explores socio-demographic and economic
predictors of the pregnancies in Amenfi West district.
Methods: The study design was a community based case-control study involving 80 cases and 220 controls. Data was collected using structured
questionnaires and analyzed by Stata version 11 to examine associations between predictors of pregnancy and background characteristics of
adolescents.
Results: Findings show that, being in school, coming from a wealthy household, contraceptive use, parental monitoring and relationship
counselling offered significant protection against adolescent pregnancy (p<0.05). However, factors such as violent parental attitudes towards
boy/girlfriend relationships, demanding financial support from adolescents for housekeeping and peer pressure from ever been pregnant friends
predisposes adolescents to pregnancy.
Conclusion: Advocacy for increased social/parental support for adolescents, education on modern contraception and availability of services are
key to preventing adolescent-pregnancies in rural communities.

Published: August 2019

Apesar da elevada riqueza de mamíferos, o real conhecimento desses animais permanece incipiente em muitas regiões do Brasil. Na maioria dos remanescentes do bioma Cerrado, as lacunas a respeito da composição desse grupo dificultam a elaboração de propostas que viabilizem sua conservação e manejo. Nesse contexto, realizou-se na Área de Proteção Ambiental (APA) Morro do Macaco, em Iporá-GO, o inventário de sua mastofauna terrestre e o registro das formas de interação existentes entre esse grupo e os moradores do entorno dessa APA. Identificou-se 23 espécies de mamíferos silvestres, das quais cinco estão ameaçadas de extinção no país. Foram observadas degradações por diferentes causas no interior da APA e a existência de conflitos entre espécies silvestres e os moradores fronteiriços. Os resultados apresentados consistem nas primeiras informações sobre a mastofauna local e devem ser considerados para se estruturar ações de manejo e conservação da área estudada e outras de semelhante perfil.
Health Benefits of Nut Consumption in Middle-Aged and Elderly Population

Published: August 2019

Aging is considered the major risk factor for most chronic disorders. Oxidative stress and chronic inflammation are two major contributors for cellular senescence, downregulation of stress response pathways with a decrease of protective cellular activity and accumulation of cellular damage, leading in time to age-related diseases. This review investigated the most recent clinical trials and cohort studies published in the last ten years, which presented the influence of tree nut and peanut antioxidant diets in preventing or delaying age-related diseases in middle-aged and elderly subjects (≥55 years old). Tree nut and peanut ingestion has the possibility to influence blood lipid count, biochemical and anthropometric parameters, endothelial function and inflammatory biomarkers, thereby positively affecting cardiometabolic morbidity and mortality, cancers, and cognitive disorders, mainly through the nuts’ healthy lipid profile and antioxidant and anti-inflammatory mechanisms of actions. Clinical evidence and scientific findings demonstrate the importance of diets characterized by a high intake of nuts and emphasize their potential in preventing age-related diseases, validating the addition of tree nuts and peanuts in the diet of older adults. Therefore, increased consumption of bioactive antioxidant compounds from nuts clearly impacts many risk factors related to aging and can extend health span and lifespan.
Research on Composite Control Strategy of Quasi-Z-Source DC–DC Converter for Fuel Cell Vehicles
Authors: Zhou Meilan , Yang Mingliang , Wu Xiaogang , Fu Jun
Published: August 2019

The DC–DC converter for fuel cell vehicles requires high gain and wide voltage input range to boost the voltage of the fuel cell. However, with the traditional boost converter, it is difficult to meet the requirements of the fuel cell vehicle power system. Based on a quasi-Z-source network DC–DC converter, this paper proposes a composite controller, which includes a feedforward compensation network and feedback control to meet the control robustness requirement of the fuel cell vehicle power system. The dynamic model of the converter is obtained by using the state space averaging method and the small-signal dynamic modeling method. The input voltage and load disturbance experiments are performed on the DC–DC converter. Moreover, the converter is tested under the worldwide harmonised light vehicle test procedure (WLTP) to validate the effectiveness of the proposed composite controller. The simulation and experiment results show that the proposed composite controller effectively enhances the converter’s ability to resist input and load disturbance, and improves the dynamic response performance of the DC–DC converter for fuel cell vehicles.

Published: August 2019

Using an optical freeform surface to realize the precision measurement of displacement has become a research focus in the present day. However, the measurement range of this method is limited by the size of the freeform surface processed. In order to overcome this difficulty, this paper presents a two-dimensional displacement measurement system with a large range, which is composed of a slope sensor and a rotating paraboloid array. The slope sensor utilizes the optical structure of an autocollimator with minor optimization, and the rotating paraboloid array expands the measurement range of the system in a discrete manner. The experimental results showed that the optimized optical system enhanced the measurement accuracy to ±0.4 μm within the range of 1500 μm and the overall measurement error was approximately ±2 μm when measured within the range of 450 mm. The developed measurement system has potential applicability for detection of errors, such as the position error and straightness error of multi-axis systems.
Multiscale Spatio-Temporal Changes of Precipitation Extremes in Beijing-Tianjin-Hebei Region, China during 1958–2017
Authors: Song Xiaomeng , Zou Xianju , Zhang Chunhua , Zhang Jianyun , Kong Fanzhe
Published: August 2019

In this study, based on daily precipitation records during 1958–2017 from 28 meteorological stations in the Beijing-Tianjin-Hebei (BTH) region, the spatio-temporal variations in precipitation extremes defined by twelve indices are analyzed by the methods of linear regression, Mann-Kendall test and continuous wavelet transform. The results showed that the spatial patterns of all the indices except for consecutive dry days (CDD) and consecutive wet days (CWD) were similar to that of annual total precipitation with the high values in the east and the low value in the west. Regionally averaged precipitation extremes were characterized by decreasing trends, of which five indices (i.e., very heavy precipitation days (R50), very wet precipitation (R95p), extreme wet precipitation (R99p), max one-day precipitation (R × 1day), and max five-day precipitation (R × 5day)) exhibited significantly decreasing trends at 5% level. From monthly and seasonal scale, almost all of the highest values in R × 1day and R × 5day occurred in summer, especially in July and August due to the impacts of East Asian monsoon climate on inter-annual uneven distribution of precipitation. The significant decreasing trends in annual R×1day and R×5day were mainly caused by the significant descend in summer. Besides, the possible associations between precipitation extremes and large-scale climate anomalies (e.g., ENSO (El Niño Southern Oscillation), NAO (North Atlantic Oscillation), IOD (Indian Ocean Dipole), and PDO (Pacific Decadal Oscillation)) were also investigated using the correlation analysis. The results showed that the precipitation extremes were significantly influenced by ENSO with one-year ahead, and the converse correlations between the precipitation extremes and climate indices with one-year ahead and 0-year ahead were observed. Moreover, all the indices show significant two- to four-year periodic oscillation during the entire period of 1958–2017, and most of indices show significant four- to eight-year periodic oscillation during certain periods. The influences of climate anomalies on precipitation extremes were composed by different periodic components, with most of higher correlations occurring in low-frequency components.
Pioneering Construction Materials through Prototypological Research

The article at hand follows the understanding that future cities cannot be built the same way as existing ones, inducing a radical paradigm shift in how we produce and use materials for the construction of our habitat in the 21st century. In search of a methodology for an integrated, holistic, and interdisciplinary development of such new materials and construction technologies, the chair of Sustainable Construction at KIT Karlsruhe proposes the concept of “prototypological” research. Coined through joining the terms “prototype” and “typology”, prototypology represents a full-scale application, that is an experiment and proof in itself to effectively and holistically discover all connected aspects and address unknowns of a specific question, yet at the same time is part of a bigger and systematic test series of such different typologies with similar characteristics, yet varying parameters. The second part of the article applies this method to the research on mycelium-bound building materials, and specifically to the four prototypologies MycoTree, UMAR, Rumah Tambah, and Futurium. The conclusion aims to place the results into the bigger research context, calling for a new type of architectural research.
Experimental Study on a “Snake-Type” Vibration Cutting Method for Cutting Force and Cutting Heat Reductions

Published: August 2019

Cutting is the foundation of manufacturing in industry. The main cutting objects include metals, ceramics, glasses, compositions, and even biological materials such as tissues and bones. The special properties of each material such as hardness, ductility, brittleness, and heat conductivity lead to either a large cutting force or a high cutting temperature. Both of these factors result in poor machinability due to rapid tool wear or break or unsatisfactory surface integrity of the material finishing surface using the conventional cutting (CC, conventional cutting) types. In nature, snakes have their own way of reducing heat accumulation on their body when moving on the hot desert surface. They move forward along an “S”-type path, so that the bottom of their body separates from the desert intermittently. In this way, the separation interval both reduces the cutting heat accumulations and effectively achieves cooling by allowing the air to go through. In addition, the acceleration of Odontomachus monticola’s two mandibles when striking a target can reach 71,730 g m/s2 within 180 ms, which can easily break the target surface by the transient huge impact. Therefore, based on a snake’s motion on the desert surface and Odontomachus monticola’s striking on the target surface, respectively, an ultrasonic-frequency intermittent cutting method, also called “snake-type” vibration cutting (SVC, snake-type vibration cutting), was proposed in this study. First, its bionic kinematics were analyzed, then the SVC system’s design was introduced. Finally, cutting experiments were conducted on a common and typical difficult-to-cut material, namely titanium alloys. Cutting force, cutting temperature, and the surface integrity of the material finishing surface were measured, respectively. The results demonstrated that, compared to conventional cutting methods, SVC achieved a maximum of 50% and 30% reductions of cutting force and cutting temperature, respectively. Moreover, the surface integrity was improved both in surface roughness and residual stress state.

Background: Colorectal cancer (CRC) is one of the leading causes of cancer-related deaths worldwide. Although early diagnosis and treatment is the most successful strategy for improving patient survival, feasible and sensitive blood biomarkers for CRC screening remain elusive. Methods: Sixty-five CRC patients and thirty-three healthy individuals were enrolled. Peripheral blood (PB) and tumor tissues from CRC patients, and PB from healthy individuals were subjected to immunophenotyping and phospho-flow analysis of cytokine-induced phosphorylated STAT (CIPS). Logistic regression was used as a classifier that separates CRC patients from healthy individuals. Results: The proportion of regulatory T cells was increased in PB from CRC patients compared to PB from healthy individuals (p < 0.05). Interestingly, peripheral T cells share several cytokine-induced phosphorylated STAT (CIPS) signatures with T cells from CRC tumor-sites. Additionally, a classifier was made using two signatures distinct between T cells from CRC patients and T cells from healthy individuals. The AUCs (area under curves) of the classifier were 0.88 in initial cohort and 0.94 in the additional validation cohort. Overall AUC was 0.94 with sensitivity of 91% and specificity of 88%. Conclusion: This study highlights that immune cell signatures in peripheral blood could offer a new type of biomarker for CRC screening.

The targeting of activated epidermal growth factor receptor (EGFR) with therapeutic anti-EGFR monoclonal antibodies (mAbs) such as cetuximab and panitumumab has been used as an effective strategy in the treatment of colorectal cancer (CRC). However, its clinical efficacy occurs only in a limited number of patients. Here, we performed whole-transcriptome analysis in xenograft mouse tumors induced by KRASG12D mutation-bearing LS174T CRC cells following treatment with either cetuximab or PBS. Through integrated analyses of differential gene expression with TCGA and CCLE public database, we identified TNS4, overexpressed in CRC patients and KRAS mutation-harboring CRC cell lines, significantly downregulated by cetuximab. While ablation of TNS4 expression via shRNA results in significant growth inhibition of LS174T, DLD1, WiDr, and DiFi CRC cell lines, conversely, its ectopic expression increases the oncogenic growth of these cells. Furthermore, TNS4 expression is transcriptionally regulated by MAP kinase signaling pathway. Consistent with this finding, selumetinib, a MEK1/2 inhibitor, suppressed oncogenic activity of CRC cells, and this effect is more profound in combination with cetuximab. Altogether, we propose that TNS4 plays a crucial role in CRC tumorigenesis, and that suppression of TNS4 would be an effective therapeutic strategy in treating a subset of cetuximab-refractory CRC patients including KRAS activating mutations.

A recent study has applied a novel statistical framework (functional linear modeling: FLM) to the study of circadian activity rhythm (CAR) in adult attention-deficit hyperactivity disorder (ADHD), pointing out the absence of the physiological post-lunch dip. The aim of the present study was to apply FLM to explore the features of CAR in pediatric ADHD. To this end, a secondary analysis of previously collected data was carried out. Twenty-four ADHD children (four females, mean age 8.67 ± 1.74) and 107 controls (C, 60 females, mean age 10.25 ± 0.48) were examined. The actigraph model Actiwatch AW64 was used to objectively monitor sleep/wake behavior and CAR. In the original study each participant wore the actigraph on the non-dominant wrist for one week. FLM was applied to examine the differences between groups in CAR. Compared with C, the CAR of ADHD children was distinguished by a higher motor activity during the whole of the daytime and within a reduced time window during the nighttime.

MoAlB is a potential candidate for high-temperature application since a dense, adherent alumina scale is formed. While, based on X-ray diffraction investigations, the formation of phase pure orthorhombic MoAlB coatings is observed, energy dispersive X-ray spectroscopy carried out in a scanning transmission electron microscope reveals the presence of Al-rich and O-rich regions within the MoAlB matrix. The oxidation kinetics of coatings and bulk is similar to the scale thickness formed on the MoAlB coating after oxidation at 1200 °C for 30 min is similar to the one extrapolated for bulk MoAlB. Furthermore, the oxidation kinetics of MoAlB coatings is significantly lower than the one reported for bulk Ti2AlC. Finally, the elastic properties measured for the as-deposited coatings are consistent ab initio predictions.

Colloidal photonic crystal (PC)-based anti-counterfeiting materials have been widely studied due to their inimitable structural colors and tunable photonic band gaps (PBGs) as well as their convenient identification methods. In this review, we summarize recent developments of colloidal PCs in the field of anti-counterfeiting from aspects of security strategies, design, and fabrication principles, and identification means. Firstly, an overview of the strategies for constructing PC anti-counterfeiting materials composed of variable color PC patterns, invisible PC prints, and several other PC anti-counterfeiting materials is presented. Then, the synthesis methods, working principles, security level, and specific identification means of these three types of PC materials are discussed in detail. Finally, the summary of strengths and challenges, as well as development prospects in the attractive research field, are presented.
