Band gap manipulation of viscoelastic functionally graded phononic crystal
Authors: Bian Zuguang , Yang Shuai , Zhou Xiaoliang , Hui David 
Published: June 2020

Abstract
In this study, band gaps of SH-waves (horizontally polarized shear waves) propagating in a thermal-sensitive viscoelastic matrix are investigated. Metallic films acting as heat sources are periodically embedded into the matrix, which establishes a periodically inhomogeneous thermal field. The homogenous matrix is therefore transformed into functionally gradient phononic crystals (PCs). A three-parameter solid model is employed to describe the viscoelasticity of the present matrix. By virtue of a transfer matrix method incorporated within a laminated model, the dispersion equation of SH-waves is finally obtained, from which the band gaps are determined. The transmission spectra of a finite-periodic PC are also solved to validate the band gaps. In numerical examples, the influences of incident angles of SH-waves and viscoelasticity of matrix on band gaps are discussed first. Then the research focuses on the means to tune the band gaps by manipulating the inputted powers of heat sources. Numerical examples demonstrate that such a strategy is effective and convenient in tuning the positions and widths of band gaps. A viscous parameter, i.e., the ratio of initial-state to final-state storage moduli, significantly affects the band locations and bandwidths, while the locations of low-order band gaps hardly move with the incident angle of SH-waves. Band gaps of several orders are expected to locate in lower-frequency domain, and the total bandwidth becomes larger as the inputted heat flux increases. This paper lays theoretical foundation to manufacture viscoelastic functionally graded PCs which can be used in frequency-selective devices.

Published: June 2020

AbstractThis study examined the coping strategies of crop farmers to pastoralist activities in Odo-Otin Local Government Area of Osun State, Nigeria. A multistage sampling technique was used to select 120 farmers. The data were collected using a well-structured questionnaire and interview and were analysed using descriptive and inferential statistical tools. The result revealed various levels of damage caused to food security by the pastoralist as follows: compaction of soil (84%), damage and eating of the crops on the field (79%), indiscriminate bush burning leading to fire outbreak on farms (73%), stealing of farm produce by herders (73%), pollution of water points (54%), killing of farmers (13%) and others. The result further revealed the coping strategies used by crop farmers: praying for peace (98%), early harvesting (95%), early planting (92%), multiple farm plots (91%), group farming (90%), relocating farm (77%), police intervention (60%), government intervention (9%), NGO intervention (9%) and insurance (4.2%). The results of Chi-square analysis showed that there is a significant relationship between the educational status (X2= 13.06,P= 0.01) and coping strategies used against pastoralist activities. Therefore, it is recommended that the government should formulate a policy that will stimulate peace among crop farmers and pastoralist to sustain food security and reduce poverty among rural dwellers, thereby transforming the rural environment into an attractive centre.
Deictic Shifting in Greek Contractual Writing (I–IV AD)
Authors: Bentein Klaas 
Published: June 2020

AbstractMuch attention has been paid to ‘deictic shifts’ in Ancient Greek literary texts. In this article I show that similar phenomena can be found in documentary texts. Contracts in particular display unexpected shifts from the first to the third person orvice versa. Rather than constituting a narrative technique, I argue that such shifts should be related to the existence of two major types of stylization, called the ‘objective’ and the ‘subjective’ style. In objectively styled contracts, subjective intrusions may occur as a result of the scribe temporarily assuming himself to be the deictic center, whereas in subjectively styled contracts objective intrusions may occur as a result of the contracting parties dictating to the scribe, and the scribe not modifying the personal references. There are also a couple of texts which display more extensive deictic alter­nations, which suggests that generic confusion between the two major types of stylization may have played a role.

Ältere Erwerbstätige in der digitalisierten Arbeitswelt – Ergebnisse der lidA-Studie
Authors: Hasselhorn Hans Martin 
Published: June 2020

Zusammenfassung
Aktuelle Analysen der deutschen lidA-Studie (www.lida-studie.de) legen nahe, dass die Digitalisierung der Arbeitswelt bei Älteren noch vornehmlich auf traditionelle digitale Arbeitsmittel beschränkt ist. Sie fühlen sich dabei allermeist sicher und sind zufrieden mit der digitalen Ausstattung. Besondere Risikogruppen für „digitalen Stress“ sind möglicherweise Berufsgruppen, die mit Menschen arbeiten. Aussagekräftige Zahlen sind vonnöten, um die Digitalisierung des Arbeitsalltags zu quantifizieren, Auswirkungen zu beschreiben und Risikogruppen zu identifizieren.

Published: June 2020

Zusammenfassung
Positive Konzepte des Wohlbefindens werden auch im Arbeitskontext verstärkt diskutiert – insbesondere Arbeitszufriedenheit und -engagement. In unserem metaanalytischen Review gingen wir der Frage nach, ob sich diese positiven Facetten arbeitsbezogenen Wohlbefindens fördern lassen und welche Merkmale der Tätigkeit (Ressourcen) dazu beitragen. Sowohl Arbeitsengagement als auch Arbeitszufriedenheit lassen sich durch tätigkeitsbezogene Ressourcen steigern, für Arbeitszufriedenheit sind soziale Ressourcen bedeutsamer als für Arbeitsengagement.
Contemporary Art Practice and Indigenous Knowledge
Authors: McMaster Gerald 
Published: June 2020

AbstractIndigenous artists are introducing traditional knowledge practices to the contemporary art world. This article discusses the work of selected Indigenous artists and relays their contribution towards changing art discourses and understandings of Indigenous knowledge. Anishinaabe artist Norval Morrisseau led the way by introducing ancient mythos; the gifted Carl Beam enlarged his oeuvre with ancient building practices; Peter Clair connected traditional Mi'kmaq craft and colonial influence in contemporary basketry; and Edward Poitras brought to life the cultural hero Coyote. More recently, Beau Dick has surprised international art audiences with his masks; Christi Belcourt’s studies of medicinal plants take on new meaning in paintings; Bonnie Devine creates stories around canoes and baskets; Adrian Stimson performs the trickster/ruse myth in the guise of a two-spirited character; and Lisa Myers’s work with the communal sharing of food typifies a younger generation of artists re-engaging with traditional knowledge.
Marianne Nicolson’s Land-Based KnowledgescapeCliff Painting
Authors: Grunewald Amina 
Published: June 2020

AbstractIndigenous epistemologies and ontologies are connected to tribal lands, resilience, and claims for sovereignty. These ways of knowing offer an indispensable resource for Indigenous communities in surviving and resisting assimilationist policies. Modes of Indigenous knowledge are not only discussed in academia and practiced in local spaces but are also integrated into artworks that promote public access to First Nations political agendas within settler nation states. Knowledgescapes can be created as conversive artscapes. They can be placed translocally but also re-integrated into First Nations lands. A reworking of the land as a tribally marked space can be traced in artworks that attack bio- and geopolitical manners of settler societies. The land-marker, place-maker, and artscapeCliff Painting(1998) by Marianne Nicolson shall serve as an exemplification of a specific knowledgescape – created for Indigenous audiences to support their claims, and for non-Indigenous audiences to open up a dialogue on colonial issues within a step-by-step decolonizing discourse.
The ‘Fast Runner’ Trilogy, Inuit Cultural Memory, and Knowledge (Re-)Production
Authors: Kilbourn Russell J.A. 
Published: June 2020

AbstractThis paper reads the Isuma ‘Fast Runner’ trilogy –Atanarjuat, The Fast Runner(2001),The Journals of Knud Rasmussen(2006),Before Tomorrow(2008) – as contemporary digital video instantiations of Inuit cultural memory and knowledge (re-)production; as fixed audiovisual texts ironically documenting and archiving a repertoire of traditional cultural folkways, reinscribing them in the present as still-living cultural practices. This is achieved in the films through Isuma’s unique approach to cinematic style, combining long takes and natural light with the freedom and unpredictability afforded by the digital format. In the end, Isuma’s openness to post-literate media forms emerges as an ideal approach to the representation of specific posthuman Indigenous identities.
The geometry relaxation and photodeactivation from the S2 state of dibenzofuran studied by ultrafast spectroscopy
Authors: Wang Lian , Zhang Song , Wang Ye , Zhang Bing 
Published: June 2020

Abstract
Dibenzofuran (DBF) has attracted much attention from scientists recently since it is applied as a photoluminescence material and pharmaceutically active compound. Since the polychlorinated derivatives are highly toxic and manifest photostability in the environment. Femtosecond transient absorption spectroscopy associated with quantum chemical calculations are employed to investigate the ultrafast excited state dynamics of dibenzofuran from the S2 state in 1,4-dioxane and ethanol, respectively. Following excitation at a wavelength of 266 nm, the S2 state is firstly populated in the Franck–Condon region and preserves the planar molecular structure of the ground state. The observed increase of the transient absorption spectra of the excited state within the first several picoseconds indicates a geometry relaxation occurring on the S2 potential energy surface. The subsequent kinetic traces of excited state absorption show that the S2 state in the adiabatic region decays to the S1 state through a fast internal conversion, followed by intersystem crossing to the T1 state with a decay time of tens and hundreds of picoseconds in ethanol and 1,4-dioxane, respectively. Finally, the deactivation processes from the S1 or T state are slow and take place on a time scale of about 20 ns.
Experimental Study of Sealing Performance Test Methods and Sealing Mechanism of Shield Tail Sealing Grease
Authors: Li Xiangqian , Yang Yuyou 
Published: June 2020

Abstract
Throughout this research, five different types of sealing grease samples were collected from the construction sites of shield tunnels and tested with the current sealing test methods. For the purpose of assessing the sealing performance more accurately, a new test method was proposed based on the test results. Through this test method, the maximum diameter of pores (MDPs) that can be blocked by sealing grease was considered as the indicator of sealing performance. Furthermore, it was found that sealing grease basically seals the micropores by forming a sealing layer. If the sizes of the micropores exceeded the MDP, the sealing grease was observed to be leaking until the seal barrier was penetrated by pressure. The MDP is not affected by pressure or time. Through the microscopic images, it was observed that the thickness of the sealing layer increased with the sizes of the micropores. The new test method was used to test the samples of prepared sealing grease with varied fiber contents and it was found that sealing performance improved with increase in fiber content while simultaneously filtration decreased.
In-Hospital Formula Feeding and Breastfeeding Duration
Authors: McCoy Marcia Burton , Heggie Pamela 
Published: June 2020

BACKGROUND:
In-hospital formula feeding (IHFF) of breastfed infants is associated with shorter duration of breastfeeding. Despite evidence-based guidelines on when IHFF is appropriate, many infants are given formula unnecessarily during the postpartum hospital stay. To account for selection bias inherent in observational data, in this study, we estimate liberal and conservative bounds for the association between hospital formula feeding and duration of breastfeeding.

METHODS:
Infants enrolled in the Minnesota Special Supplemental Nutrition Program for Women, Infants, and Children were selected. Breastfed infants given formula were matched with infants exclusively breastfed (n = 5310) by using propensity scoring methods to adjust for potential confounders. Cox regression of the matched sample was stratified on feeding status. A second, more conservative analysis (n = 4836) was adjusted for medical indications for supplementation.

RESULTS:
Hazard ratios (HR) for weaning increased across time. In the first analysis, the HR across the first year was 6.1 (95% confidence interval [CI] 4.9–7.5), with HRs increasing with age (first month: HR = 4.1 [95% CI 3.5–4.7]; 1–6 months: HR = 8.2 [95% CI 5.6–12.1]; &gt;6 months: HR = 14.6 [95% CI 8.9–24.0]). The second, more conservative analysis revealed that infants exposed to IHFF had 2.5 times the hazard of weaning compared with infants who were exclusively breastfed (HR = 2.5; 95% CI 1.9–3.4).

CONCLUSIONS:
IHFF was associated with earlier weaning, with infants exposed to IHFF at 2.5 to 6 times higher risk in the first year than infants exclusively breastfed. Strategies to reduce IHFF include prenatal education, peer counseling, hospital staff and physician education, and skin-to-skin contact.
Komodifikasi Agama dalam Gerakan Majlis Tafsir Al-Qur’an (MTA) di Surakarta
Authors: Faddad Zaki , Mardiah Anisatul 
Published: June 2020

This paper aims to describe the process of religious commodification within Majlis Tafsir Al-Qur’an (MTA) in Surakarta. The teaching and practices of MTA (such as the doctrine of salvation, leadership and brotherhood, and the practice of pengajian) have effectively constructed social belonging among its members. It represents the production of social identity, loyalty, and solidarity. Besides, the charisma of its leader, Ahmad Sukino, has become a center of social appeal. Social belonging and charisma become influential elements for the MTA members. One of the MTA compelling-doctrines is the doctrine of jihad harta. It occurs through mobilizing the contribution of MTA members and commodifying pengajian. Referring to Kitiarsa (2010), there are at least two reasons behind this religious commodification: commodity and market. MTA monetizes religion-based objects, such as brochures, books, and videos. Pengajian becomes a market where the process of commodification follows.

Objetivo: El Trastorno por Déficit de Atención con Hiperactividad/impulsividad (TDAH) es una de lasdificultades de aprendizaje más comunes en las escuelas chilenas. Se caracteriza por un patrón defuncionamiento atípico en atención e inhibición, con fuerte compromiso de otras funciones ejecutivas.Uno de los desafíos que plantea este trastorno está referido al proceso de diagnosis, el cual no sueleser suficientemente preciso. Se pretende explorar las diferencias en la distribución de dos muestrasde estudiantes con y sin TDAH diagnosticadas con una escala de observación conductual a través de laevaluación de las funciones ejecutivas de atención, inhibición y flexibilidad cognitiva.
Método: En este estudio se evaluó a 132 escolares, 66 con TDAH y 66 sin TDAH, en las variables deatención, inhibición y flexibilidad cognitiva de un colegio de la ciudad de Concepción en Chile. Secontrastó el rendimiento cognitivo con los diagnósticos y se reagrupó a los estudiantes en los subtiposconocidos del trastorno.
Resultados: La evaluación neuropsicológica mostró que en el grupo con TDAH había alumnos queno cumplían los criterios diagnósticos para estar incluidos en él. En el grupo sin TDAH se observó unfenómeno semejante. En ambos grupos la evaluación neuropsicológica de la atención y la inhibiciónresultaron útiles para diagnosticar con mayor certeza y para determinar el subtipo al que pertenecíacada estudiante con TDAH detectado. La flexibilidad cognitiva solo permitió diferenciar a los sujetos cony sin TDAH.
Conclusiones: En ambos grupos estudiados fue posible encontrar sujetos mal diagnosticados; el sobrediagnóstico fue de 43,93 % en el grupo con TDAH, mientras que el infradiagnóstico fue de 42,42 % enel grupo sin TDAH.

Published: June 2020

Introduction
Physician wellness and burnout are topics of intensediscussion and study, however, less is known about rural physicianburnout. The aim of this study was to assess levels of physicianburnout in the rural Kansas community of Salina.
Methods
An electronic, confidential survey was conducted among145 physicians with active privileges at the local health center and/orsurgical center. The survey included demographic features, practicecharacteristics, and the abbreviated Maslach Burnout Inventory™(aMBI). In addition, survey participants were invited to provide freetextresponses to questions concerning specific causes of burnoutand mechanisms to combat feelings of burnout.
Results
Of 145 invited, 76 physicians completed the survey. Thirty-six respondents self-identified as primary care physicians, 22as subspecialists, and 18 as surgeons. aMBI scores for emotionalexhaustion (EE), depersonalization (D) and personal accomplishment(PA) ranged from 0 to 18. The mean EE score was 8.4 (SD =4.9), mean D score was 4.8 (SD = 3.9), and mean PA score was 15.2(SD = 2.8). Using tertiles, physician burnout (i.e., those in the firsttertile) for EE was 39% (30/76), D was 34% (26/76), and PA was41% (31/75); 22% of physicians surveyed scored high on both EEand D as measured by tertiles, suggestive of more serious burnout.No significant differences in aMBI scores were observed for demographicfeatures or practice characteristics; physicians who workedwith medical students had higher PA scores. Contributing to burnoutwere demands of documentation and difficult patient encounters,while true time away might ameliorate rural physician burnout.
Conclusions
As measured by aMBI constructs, burnout is prevalentamong the responding rural physicians practicing in the Salina community.
