Including Partners in Discussions of Sexual Side Effects from Breast Cancer: A Qualitative Study of Survivors, Partners, and Providers
Authors: Shaffer Kelly M , Kennedy Erin , Glazer Jillian , Clayton Anita , Cohn Wendy , Reese Jennifer Barsky , Millard Trish , Ritterband Lee Michael , Showalter Shayna
Published: March 2021

Objective: To assess breast cancer survivor, partner, and provider perspectives on the importance of including partners in discussions between providers and survivors about cancer-related sexual concerns. Methods: Partnered female breast cancer survivors (N=29) completed online surveys, and intimate partners of breast cancer survivors (N=12) and breast oncology providers (N=8) completed semi-structured interviews. Themes were derived from thematic content analysis.Results: Among survivors who reported a discussion with their provider, fewer than half indicated their partner had been present, despite most survivors expressing it was – or would have been – helpful to include their partner. Partners also largely indicated being included was or would have been helpful, when welcomed by the survivor. Providers similarly emphasized the importance of survivors’ autonomy in deciding whether to discuss sexual concerns in the presence of a partner. Conclusions: Partners were infrequently included in conversations about cancer-related sexual concerns, even though survivors, partners, and providers alike expressed value in these discussions occurring with the couple together – when that is the survivor’s preference. Practice implications: Providers should clearly communicate that survivors may include their partner in discussions about cancer-related sexual concerns, making use of accessible intervention strategies like telehealth and digital health to increase feasibility.

Probing the neural basis rational numbers: the role of inhibitory control and magnitude representations
Authors: Rosenberg-Lee Miriam
Published: March 2021

Rational numbers, such as fractions, decimals and percentages, are a persistent challenge in the mathematics curriculum. An underappreciated source of rational number difficulties are whole number properties that apply to some, but not all, rational numbers. I contend that mastery of rational numbers involves refining and expanding whole number representations. Behavioral evidence for the role inhibitory control and magnitude-based processing of rational numbers support this hypothesis, although more attention is needed to task and stimuli selection, especially among fractions. In the brain, there is scant evidence on the role of inhibitory control in rational number processing, but surprisingly good correspondence, in the parietal lobe, between the handful of neuroimaging studies of rational numbers and the accumulated whole number literature. Decimals and discrete nonsymbolic representations are fruitful domains for probing the neural basis role of whole number interference in rational number processing.
Change in Anti-COVID-19 Behavior and Prejudice against Minorities during the COVID-19 Pandemic: Longitudinal Evidence from Five European Countries

Published: March 2021

In the COVID-19 pandemic, it is vital to identify factors increasing behaviors that limit the transmission of COVID-19 (i.e., anti-COVID-19 behavior) and factors protecting against the negative consequences of the pandemic on societies (i.e., prejudice). A simultaneous investigation of a change in anti-COVID behavior and prejudice during the pandemic is essential because some factors (e.g., fear of COVID-19) could increase both outcomes, whilst other factors (e.g., norms in anti-COVID behavior or intergroup contact in prejudice) could bring desirable changes in one outcome without negatively affecting the other. In a three-wave longitudinal study (NT1 = 4275) in five European countries from April to October 2020, we employed a latent change score model to distinguish between intra- and inter-individual changes in anti-COVID-19 behavior and prejudice. On the intra-individual level, anti-COVID-19 behavior was increased by anti-COVID-19 norms; and prejudice against migrants from the Middle East was influenced by positive and negative direct and mass-media intergroup contact.
Learning by Explaining Orally or In Written Form? Text Difficulty Matters
Authors: Jacob Leonie , Lachner Andreas , Scheiter Katharina
Published: March 2021

In this experiment, we examined whether text difficulty moderates the effect of the modality of explaining on students’ learning. Students (N = 115) read a high-difficult and a low-difficult text. Additionally, students generated either a written or an oral explanation. A control group of students retrieved the content. For the low-difficult text, we found no significant differences between conditions. For the high-difficult text, however, oral explaining yielded better comprehension than writing explanations. The retrieval condition showed the lowest performance. Mediation analyses revealed that the effect of explaining modality was mediated by the number of personal references and the comprehensiveness of the generated explanations. Our findings suggest that the effect of explaining modality emerges when students are required to learn from difficult text materials. Furthermore, the findings show that oral explaining is effective, as it triggers distinct generative processes due to increased social presence during explaining.
Transit-Induced Gentrification and Displacement: The State of the Debate
Authors: Delmelle Elizabeth C.
Published: March 2021

Investments in new transportation infrastructure hold the potential to transform the urban socioeconomic landscape by reshaping accessibility and by encouraging new developments around these investments. This chapter outlines the theoretical arguments for why and how transport, specifically rail transit, is expected to impact the socioeconomic composition of neighborhoods and reviews the relevant empirical literature on the subject. Neighborhood socioeconomic change, including gentrification, can be viewed as the product of shifts in residential sorting of residents reacting to the placement of a new (transit) amenity which may place increased demand for living in a particular area. This demand may place an upward pressure on nearby housing values and rents, affecting the socioeconomic composition of those willing and able to afford these price premiums, thus spurring or accelerating gentrification. Rising land values may also lead to the disproportionate exit of lower-income residents unable to keep up with elevated rents or property taxes. To date, the empirical evidence on the link between transport investments and gentrification has mixed findings, very often underscoring the importance of local context in directing a neighborhood’s path. Research has overwhelmingly centered on aggregate neighborhood changes, but several studies have recently emerged that center on individual movements that give rise to these neighborhood-scale outcomes.

Published: March 2021

In the spring of 2018, the Society for American Archaeology (SAA) initiated the process of updating and revising the SAA Principles of Archaeological Ethics. As part of this process, the SAA created the Task Force on Revising the SAA Principles of Archaeological Ethics: Stage Two (TF-2), which would collect, organize, and analyze results from a survey (see Rakita and Gordon, this issue, for more details about the work of TF-2). This survey was available online between April and June of 2020 and was open to SAA members and non-members. Consisting of 31 questions, the survey received responses from 1,542 people (including 1,112 SAA members). A key objective was to gauge reactions and attitudes of respondents toward the current SAA Principles of Archaeological Ethics. This article reports the survey results relevant to those principles, which can be found at https://www.saa.org/career-practice/ethics-in-professional-archaeology and which are reprinted in this issue of the Record. We first summarize the respondents’ demographics, and how they are using the principles. We then summarize reactions to each of the nine principles and responses to questions about how the principles address situations and concerns. These data provide an indication of the overall level of satisfaction with the current SAA Principles of Archaeological Ethics. Finally, we conclude with some guidance for considering future revisions of the principles.
Vote, Tweet, Campaign, Repeat: Using Twitter to predict environmental voting intentions
Authors: Greenwell Matthew , Johnson Thomas
Published: March 2021

Government policies are key to combating climate change and biodiversity loss, however political action requires electoral support. Engaging with the electorate through social media is an integral part of political communications, informing voters on politicians’ voting intentions. Here, we examine whether environmental messaging on Twitter by UK politicians can be used to predict the likelihood of them voting for pro-environmental measures. Using historical Twitter data and voting records, we determine that environmental messaging has increased over the last decade, but the probability of voting environmentally has not. Instead, voting trends are highly heterogenous over time, varying by political party. However, after accounting for party effects, politicians with higher levels of environmental messaging are more likely to vote against party lines in favour of environmental measures. This work suggests that environmental messaging can be used to inform voting intentions, but is a poor predictor compared to political party association.

Authors: Subedi Abatar
Published: March 2021

This paper aims to reveal the difficulties as experienced by graduate students while learning abstract algebra at master's degree in mathematics education in the first month of their enrollment. For, I adopted a case study of five students, interviewed them with the help of interview guidelines and observed their behaviors in the classroom, and triangulated this information with researcher’s experiences to explore the difficulties in learning abstract algebra. I used inductive method to analyze the information and concluded that graduate students have experienced several difficulties in learning abstract algebra including the difficulties in conceptualizing algebraic facts, constructing examples and non-examples; and proving theorems. Finally, the study suggests that graduate teaching need to focus on conceptual and procedural understanding of students, and emphasizing to construct examples and non-example as much as possible to improve students’ learning.

Authors: Yadav Prabhu Ray
Published: March 2021

The paper aims to shed light on the beauty of inter-cultural relations in the third millennium. It endeavours to uplift the academic disciplines like identity, diversity and culture. A mutual understanding is a well known approach/method to develop the beauty of inter-cultural relations. The purpose of inter-cultural relations study is to strengthen social understanding around the world. Such relations play an important role to implement the national and international awareness. Inter-cultural relations, as an integral part of caste, culture, and religion, enlighten people about the distant and distinct cultural relations outside their own cultures. Such knowledge of inter-cultural relationsem powers people to protect their own cultures too.The concept of inter-cultural relations strengthens our economic, political and social stability. After the end of the bipolar world, inter-cultural relations have expanded our mutual/bilateral relations. The very interaction on inter-cultural relations becomes the cornerstone of international relations. Arguing in favour of intercultural relations is the way to reach the highest of the high path in human development.

The Status of the Artist, Cultural Rights and the 2005 Convention
Authors: Vickery Jonathan
Published: March 2021

This article is written in the spirit of a festschrift, in honour of recently retired Professor Milena Dragićević Šešić. Once Rector of the University of Arts, Belgrade, and the UNESCO Chair in Cultural Policy and Management, Professor Milena’s work and personal charisma have made a European-wide impact on both students and scholars, artists and activists. Her example is one of a university academic who is socially-engaged, politically astute, and who possseses the communication skills that have enabled her to participate in cultural politics at the highest level. Her contribution towards cultural thought and freedom of expression in her own country of Serbia (Yugoslavia until the early 1990s) will offer an important intellectual legacy. The aim of this article is to contribute to the emergence of this legacy by discussing our current policy understanding of artistic freedom in a way that amplifies its intellectual complexity as well as its policy necessity. I argue that cultural policy has struggled to defend, artistic freedom, despite many relevant intellectual resources provided by UNESCO; however, there remains hope in the form of a critical attention to the terms of the 2005 Convention and the historical discourse of culture and development from which it emerged.

Like most plantation plants in general, rubber can be attacked by various diseases originating from fungi, pests, animals and even cancer cells. For that we need a method capable of diagnosing rubber disease. In previous research related to the diagnosis of plant diseases, among others, using the Dempster Shafer method, the Certainty factor method and forward chaining. This study developed an analysis of the results of the diagnosis of rubber plant disease using the Mamdany Fuzzy method. The choice of this method departs from research on fuzzy mamdany which states that the fuzzy mamdany method is able to resemble the intuitive way the human brain works. It is hoped that with this method, the diagnosis of rubber plant disease can help farmers detect symptoms earlier so that the productivity of rubber plantation products can be achieved. increased. This study used rubber plant disease data from the Jambi Provincial Plantation Office in Jambi City. From the results of calculations carried out in diagnosing rubber plant disease, as many as 161 rubber plant object data were equipped with 33 symptom identities and a diagnosis from plantation data, then tested 60 rubber plant data without a diagnostic label, we obtained an accuracy value of 81.28%. Likewise, testing by randomizing training data with Cross Validation obtained close results.
“A Greater Compass of Voice”: Elizabeth Taylor Greenfield and Mary Ann Shadd Cary Navigate Black Performance
Authors: Moriah Kristin
Published: March 2021

The work of Elizabeth Taylor Greenfield and Mary Ann Shadd Cary demonstrate how racial solidarity between Black Canadians and African Americans was created through performance and surpassed national boundaries during the nineteenth century. Taylor Greenfield’s connection to Mary Ann Shadd Cary, the prominent feminist abolitionist, and the first Black woman to publish a newspaper in North America, reveals the centrality of peripatetic Black performance, and Black feminism, to the formation of Black Canada’s burgeoning community. Her reception in the Black press and her performance work shows how Taylor Greenfield’s performances knit together various ideas about race, gender, and nationhood of mid-nineteenth century Black North Americans. Although Taylor Greenfield has rarely been recognized for her role in discourses around race and citizenship in Canada during the mid-nineteenth century, she was an immensely influential figure for both abolitionists in the United States and Blacks in Canada. Taylor Greenfield’s performance at an event for Mary Ann Shadd Cary’s benefit testifies to the longstanding porosity of the Canadian/US border for nineteenth century Black North Americans and their politicized use of Black women’s voices.

Authors: S. Misch Emily , Stevens Christina , S. Misch Emily , Getz Anne , Hink Eric , Terella Adam
Published: March 2021

Fibrous dysplasia (FD) is an uncommon non-malignant bony tumor in which normal bone is replaced by disorganized fibro-osseous tissue. It most often involves the femur, ribs, and craniofacial skeleton and is commonly diagnosed in adolescence or early adulthood. Involvement of the paranasal sinuses is rare, and there is a relative paucity of case reports in the literature. Here, we report a case of FD of the frontal sinus in a 22-year-old male initially presenting with acute onset periorbital emphysema after nose-blowing. Radiographic examination revealed an expansile lesion with “ground-glass” appearance. The patient underwent resection and reconstruction by combined endoscopic and external approach with osteoplastic flap by a multidisciplinary team. The diagnosis of FD was confirmed by permanent histopathology. This report reviews the presentation and treatment of FD of the paranasal sinuses and details a combined external and endoscopic approach to resection of the frontal sinus mass.
Advantages of biomass compared to traditional fuels
Authors:   National University of Life and Environmental Science of Ukraine, Stepasyuk L. , Nahorna O. ,   National University of Life and Environmental Science of Ukraine
Published: March 2021

Given Ukraine's high dependence on imported energy, primarily natural gas, and the availability of great biomass potential, it has been proven that bioenergy is one of the strategic directions of the sector's development in renewable energy sources. It is determined that the pace of bioenergy development in Ukraine still lags significantly behind European ones. It is established, that in the developed countries of the world use of biomass as a source of energy continues to play an important role because of a significant increase in prices for oil and gas, as well as the growing demand for protection of the environment. Therefore, the introduction of modern technologies for continuous energy production from biomass is an important condition for the solution of problems of supply of energy and prevent degradation of the environment. The possibility of using biofuels in the Kyiv region is proved, the investment attractiveness of this region as a source of thermal energy is revealed. The methodical approach to estimating the theoretical potential of waste due to the use of alternative energy sources is substantiated. The theoretical energy potential of the biomass of by-products of agricultural crops of private enterprise "Sosnova" was assessed, which made it possible to determine the prospects of an agricultural enterprise in the energy supply of the Kyiv region at the expense of biofuels. According to the generally accepted method, the theoretical energy potential of straw and vegetable waste of private enterprise "Sosnova" was calculated, which in the market turnover in 2019 amounted to 8392 tons of oil equivalent. It was determined that the predominant type of biomass in the studied enterprise were corn stalks and wheat straw. On the example of the object of the school, which is located near the investigated enterprise, the calculation of savings on heating by replacing the traditional type of fuel (natural gas) with biofuel. The calculations show that due to biofuels the company can provide 28% of the school's need for the heating season. The savings will be - 60.6 thousand UAH and its use allow you to save about 43% of fuel annually.
Managing Calcified Coronaries: the Bugaboo of Percutaneous Coronary Intervention
Authors: Dash Debabrata
Published: March 2021

Background Percutaneous coronary intervention (PCI) of lesions with heavily coronary artery calcium (CAC) still represents a challenge for interventionists, with increased risk of immediate complications, late failure due to stent underexpansion and malapposition, and consequently poor clinical outcome. In this focused review, we provide the summary of principles, technique and contemporary evidence for various existing and emergent plaque modifying strategies. Main text PCI of lesions with heavy CAC still poses a challenge for the interventionists due to an increased risk of incomplete lesion preparation with subsequent suboptimal stent deployment and higher rates of acute and chronic stent failure. With the emergence of many novel devices and technologies, the treatment of lesions with heavy CAC has become increasingly feasible, safe and predictable. It seems likely that combining enhanced intravascular imaging modalities with traditional or new dedicated tools for the treatment of such lesions grant better lesion preparation. This optimizes delivery and deployment of drug-eluting stents translating into improved patient outcome. Conclusion The lesions with significant CAC are likely to surge due to aging population and increased rates of diabetes and chronic renal disease. The optimal therapy for such lesions is multi-adjunctive and requires the availability of several modalities including intracoronary imaging which could impact the clinical outcome favourably.
Cardiac Computed Tomography versus 3D-Transesophageal Echocardiography in Preprocedural Planning of Left Atrial Appendage Closure
Authors: Heinrich Jaroslaw , Al-Kassou Baravan , Omran Heyder
Published: March 2021

Aim: Preprocedural imaging of the left atrial appendage (LAA) plays a crucial role in the process of LAA closure (LAAC). This study aimed to compare the influence of preprocedural planning of the LAAC with 3D-transesophageal echocardiography (TEE) and cardiac computed tomography (CCT) versus 3D-TEE alone in patients who underwent LAAC with an Amplatzer Cardiac Plug or Amulet. Materials and Methods: In a retrospective study, 176 patients received a preprocedural 3D-TEE and CCT and 167 patients a 3D-TEE only. Both groups had similar patient characteristics and indications for LAAC. Results: There was no difference in terms of procedural success, procedure time, amount of contrast medium, fluoroscopy time, or radiation dose. Patients with CCT/3D-TEE had a longer hospital stay on average. Besides, there was a different incidence of renal diseases (49% for 3D-TEE versus 27% for CCT/3D-TEE; p < 0.001). The number of periprocedural adverse events was comparable. A device-related thrombus occurred three times in each group, and the peri-device leaks reported were similar. Conclusion: A preprocedural CCT does not decrease major adverse events or improve outcome in patients undergoing LAAC.

Witnessing: Virtual Conversations
Authors: Angel-Ajani Asale , Dean Carolyn J. , McLagan Meg
Published: March 2021

This special feature presents curated excerpts from two virtual conversations that the editors (Liana Chua and Omri Grinberg) held with anthropologist and author Asale Angel-Ajani, historian Carolyn J. Dean and anthropologist and filmmaker Meg McLagan on the theme of witnessing. Beginning with the participants’ reflexive discussions of how they came to work on witnessing, the conversations delve into several intertwined questions and debates. These include the politics and impacts of witnessing; the performativity of witnessing and the subjectivities involved; the evolving place and practice of witnessing in the contemporary post-truth, digitally saturated milieu; the ‘dark side’ and other problematics of witnessing; how different disciplines witness and represent witnessing; and the question of what scholars can do to witness or bear witness in the present.

Sweet mock orange f. golden dwarf (Philadelphus coronarius L. f. aureus nanus) is a promising ornamental shrub in green building within Central Russia. In the Orel Region, this species has a limited occurrence due to the lack of quality planting material, which warrants research into rhizogenesis of P. coronarius f. aureus nanus stem cuttings during soﬅwood graﬅing. Trials were conducted during 2017-2019 in triplicate, 20 cuttings each, adhering to the common woody plant soﬅwood graﬅing propagation technique. Two yearling types were used, side shoots and innovations. Experimental setups: 1 — control (water); 2 — aqueous indolebutyric acid (IBA) 50 mg/L at 18-h exposure; 3 — bottom cutting powdering with 0.5 g/kg active coal-IBA mixture; 4 — bottom cutting treatment with 50 mg/L IBA at 18-h exposure followed by powdering with 0.5 g/kg active coal-IBA mixture. Setup 2 (IBA 50 mg/L) rendered the highest positive eﬀect on the rooting and reproduction of side shoot and innovation-derived stem cuttings. Te best cutting root system biometry (number and length of 1st order roots) was obtained in setup 2 with the innovation cuttings (10.50 roots of 4.53 cm) compared to the side-shoot ones (9.81 roots of 3.68 cm).

The aim of the study. Carry out a comparative analysis of the support ability of human jaw bone tissue in monocortical and bicortical installation of a mini-implant of own design OMG.

Research methods. In order to study biomechanical characteristics of developed OMG mini-implant and bone tissue capacity during monocortical and bicortical installation, the finite element method (MSE) was used. The scheme and finite element 2-D model of bicortical installation of OMG mini-implant (length 8 mm, diameter 1.8 mm) provided full penetration through one layer of cortical bone equal to 1 mm, the entire cancellous bone and immersion in the second layer of cortical bone by 0, 5 mm. No implantation was immersed in the second cortical layer of bone during monocortical installation. A single force load of 1 N was applied in the horizontal direction parallel to the cortical plate of the bone.

Results of the study. One of the most important factors leading to the success of the use of a mini-implant is its stability in the process of orthodontic treatment. Quite a high level of failure in the monocortical installation of mini-screws has led to the search for better methods to ensure the stability of their use. This was a bicortical method of fixation, based on the placement of the minig screw in the thickness of the two cortical plates of the jaws. Area for such installation of mini-screws can be a site of a palate and alveolar sprouts at installation of miniimplants through all its thickness.

As shown by our data on the use of the finite element method under the force load of the biomechanical system "bone - mini-implant", the stress concentration zone is located in the area of the cortical bone of the jaw.

The results of the calculation of the maximum stresses (σmax, MPa) and the maximum possible displacements (umax, mm) of the mini-implant in the biomechanical system "bone - mini-implant" in monocortical installation were, respectively, 8.27 MPa and 0.300 * 10-8 mm and in bicortical installation 6.00 MPa and 0.201 * 10-8 mm.

The bicortical method of fixing the mini-implant in the jaw bones significantly increases the ability to resist deformation of this type of biomechanical system under force loads of the mini-implant.

In the bicortical method of mini-implant placement, the extreme values of equivalent according to Mises stresses in the upper part of the cortical bone of the jaw are reduced by 27%. This can be explained by a significant increase in the area of contact due to the two layers of the cortical bone of the jaw with the surface of the mini-implant.

Conclusion. The bicortical method of installing mini-implants is a more effective and reliable way to provide skeletal support during orthodontic treatment.

Forest cover changes were influenced by many factors, some of which were biophysical characteristics, socio-economic conditions, and community cultural. The behavior of forest cover changes in each of Indonesia's regions varied, either its rate or its driving factors. The establishment of village typologies to categorize village administrative areas becomes important to see the driving factors that trigger forest change in each typology. The objective of this study was to develop the village typology and to identify the driving forces of forest cover change in each village in Kubu Raya Regency, West Kalimantan. The development of village typology was done by applying the clustering approach with standardized euclidean distances. Based on the proportion of forest in 2015, the study found that there are two village typologies within the study area with 81% OA. The study also recognized that the most significant driving forces of forest cover change in T1 were the distance from rivers (X2) and settlements (X3), whereas in T2 were the distance from roads (X1) and the edge of forest in 2015 (X9). The study concludes that the proximity from the center of the human activities holds a significant influence on the behavior of forest cover changes.
