Authors: Zakrzewski Stanisław , Stasiak Bartłomiej , Klepaczka Tomasz , Wojciechowski Adam
Published: July 2022

Virtual Reality (VR) combined with near real-time EEG signal processing can be used as an improvement to already existing rehabilitation techniques, enabling practitioners and therapists to get immersed into a virtual environment together with patients. The goal of this study is to propose a classification model along with all preprocessing and feature extraction steps, able to produce satisfying results while maintaining near real time performance. The proposed solutions are tested on an EEG signal dataset, containing left/right hand motor imagery movement experiments performed by 52 subjects. Performance of different models is measured using accuracy score and execution time both in the testing and training phase. In conclusion, one model is proposed as optimal with respect to the requirements of potential patient rehabilitation procedures.
An impact of gap acceptance on road safety: A critical systematic review
Authors: Bhatt Khushbu , Shah Jiten
Published: July 2022

An uncontrolled intersection is a critical area for crashes that depends on macroscopic traffic parameters. While the intersection is the potential of the center of crashes due to inappropriate decision of driver. Therefore, the study focuses on the effect of the gap acceptance parameter for the safety of drivers at an uncontrolled intersection. To examine, a systematic review of the literature is implemented to understand the different parameters, their impact, and models developed by the researchers. Additionally, it is demonstrated that the crashes are highly affected by the gap acceptance and the different models are formed to estimate the critical gap for different road sections under homogeneous and heterogeneous traffic conditions. However, it is not possible to definitively conclude the best model to evaluate the gap acceptance factor but can be preferred to reduce the severity of crashes. Nonetheless, most studies remain inconclusive, there is an emerging trend in the literature suggesting the increase of the crash risk at an uncontrolled intersection. Lastly, it is most important to mention the model suitability based on empirical studies commenced under the strong limitations. Consequently, there is a need for research in this area to correlate the gap acceptance with road safety to reduce the severity of accidents to improve the existing transportation system.
Attaining a good primal solution to the uncapacitated transportation problem
Authors: Juman Z.A.M.S. , Nawarathne N.G.S.A. , Hisam M.S.M.
Published: July 2022

Transportation of products from sources to destinations with minimal total cost plays an important role in logistics and supply chain management. The Uncapacitated Transportation Problem (UTP) is a special case of network flow optimization problem. The prime objective of this UTP is to minimize the total cost of transporting products from origins to destinations subject to the respective supply and demand requirements. The UTP consists of special network structure. Due to the special structure of this problem, the transportation algorithm is preferred to solve it. The transportation algorithm consists of two major steps: 1) Finding an Initial Feasible Solution (IFS) to TP and 2) Examining the optimality of this IFS. A better IFS generates a lesser number of iterations to obtain a Minimal Total Cost Solution (MTCS). Recently, Juman and Nawarathne (2019)’s Method was introduced to find an IFS to UTP. In this paper, the Juman and Nawarathne (2019)’s Method is improved to get a better IFS to a UTP. A comparative study on a set of benchmark instances illustrates that the new improved method provides better primal solutions compared to the Juman and Nawarathne (2019)’s Method. The proposed method is found to yield the minimal total cost solutions to all the benchmark instances.
Analysis of railway commuting factors and customers patronage in Lagos State, Nigeria
Authors: Adanikin Ariyo , Adeoye Itunuoluwa , Ajayi Joseph
Published: July 2022

Railway transportation is a critical component of countries' transportation sectors worldwide. This is because, in the movement of goods and persons, railway transport networks have a clear advantage over other modes of transportation. However, despite the positive outlook, Nigeria's railway transportation networks have faced several challenges to the country's economic and social development, especially in overpopulated cities like Lagos State. The study population consists of 125 railway transportation users in Lagos state. The data were analyzed using descriptive, multiple and Partial Least Square Structural Equation Modeling (PLS-SEM). The study revealed that safety is the highest predictor of customer patronage amongst railway commuters in Lagos state. This is followed by price, travel time and service quality. This indicates that if the safety of the railway commuters (customers) is guaranteed, they will continue to use the train regardless of the service quality being offered to them. The study recommended that Public-Private Partnership (PPP) should be encouraged in running the affairs of the Nigerian railways for increased efficiency and that industry players need to be proactive by ensuring adequate professionalism in the sector and putting in place modern railway transport facilities.
Guns, Classrooms, and Politics: Eliciting and Reflecting Upon Education Student Beliefs in the Age of School Shootings
Authors: Rigney James K. , Jeter Gage
Published: July 2022

Unearthing the perspectives students bring with them in their college-level education coursework is especially important as education instructors are tasked with interrupting the unexamined proliferation of dominant ideologies among future educational professionals. The introduction to education course serves as an important site for this interrogation. One trend largely unexplored in the scholarly literature is the pedagogical use of controversy in introduction to education coursework. This study analyzes student discussion of the controversy of school gun violence within a redesigned introduction to education course. Data for this study come from student postings and final reflection papers in an online section of that course. Qualitative analysis of student thinking reveal three themes regarding U.S. school gun violence: gun violence as political intrusion into schools, gun policy as marginalizing and legitimizing presence, and gun use as professional boundary for teachers. These themes provide insight into the ways education students conceptualize teachers, professional educators, and the context of schooling. The student interactions and reflections in this study also suggest that scaffolded discussions of school gun violence present a poignant opportunity for education coursework to foster authentic student reflection on the policy, politics, and professions associated with American education.

Local Experts’ Observations, Interpretations, and Responses to Human-Polar Bear Interactions in Churchill, Manitoba
Authors: Schmidt Aimee L. , Loring Philip , Clark Douglas A.
Published: July 2022

Since interactions and conflicts between polar bears (Ursus maritimus) and people are reportedly increasing across the Arctic, there is a pressing need to better understand how such conflicts can be prevented or their outcomes ameliorated. A great deal of knowledge about what strategies work for both preventing and mitigating human-polar bear conflicts lies with local experts, yet this knowledge has often remained relatively inaccessible to contemporary wildlife managers. This study had three main aims: to document and synthesize local knowledge of polar bear behaviour in Churchill, Manitoba, to characterize perceptions and interpretations of polar bears, and to examine the linkage between local experts’ knowledge, perceptions, and actions. We identified a suite of bear behaviours that local experts consistently observe and interpret as cues to the bears’ intent. These behaviours are not unique to this locale. Nevertheless, differences in perspectives on the predictability of polar bear behaviour and in interpretations of the nature of bears significantly influence study participants’ strategies for responding to bears. Our findings demonstrate that human-related factors are more complex than current models of human-bear interactions account for, so there is a need to develop richer models for understanding what motivates and influences human behaviours and responses towards bears.
Killer Whale (Orcinus orca) Pulsed Calls in the Eastern Canadian Arctic
Authors: Sportelli Jessica J. , Jones Joshua M. , Frasier Kaitlin E. , Westdal Kristin H. , Higdon Jeff W. , Hildebrand John A.
Published: July 2022

Killer whales (Orcinus orca) produce a variety of acoustic signal types used for communication: clicks, whistles, and pulsed calls. Discrete pulsed calls are highly stereotyped, repetitive, and unique to individual pods found around the world. Discriminating amongst pod specific calls can help determine population structure in killer whales and is used to track pod movements around oceans. Killer whale presence in the Canadian Arctic has increased substantially, but we have limited understanding of their ecology, movements, and stock identity. Two autonomous passive acoustic monitoring (PAM) hydrophones were deployed in the waters of Eclipse Sound and Milne Inlet, in northern Baffin Island, Nunavut, Canada, in August and September 2017. Eleven killer whale pulsed call types, three multiphonic and eight monophonic, are proposed and described using manual whistle contour extraction and feature normalization. Automated detection of echolocation clicks between 20 and 48 kHz demonstrated little to no overlap between killer whale calls and echolocation presumed to be narwhal, which suggests that narwhal remain audibly inconspicuous when killer whales are present. Describing the acoustic repertoire of killer whales seasonally present in the Canadian Arctic will aid in understanding their acoustic behaviour, seasonal movements, and ecological impacts. The calls described here provide a basis for future acoustic comparisons across the North Atlantic and aid in characterizing killer whale demographics and ecology, particularly for pods making seasonal incursions into Arctic waters.

En este trabajo procuraremos reflexionar sobre las huellas que han quedado en el patrimonio documental, bibliográfico y arquitectónico de Córdoba, de las mujeres que transitaron la instancia inquisitorial o que estuvieron vinculadas al accionar de la comisaría de Córdoba durante el siglo XVIII y la primera década del XIX. Es decir, escudriñaremos desde una perspectiva de género los rastros que existen de ellas, así como las políticas de acceso y visibilización que implementan las instituciones que acogen documentos de origen oficial, literatura jurídica que solo una élite leía y poseía; como también, edificios religiosos y museos locales.
Conectividad fluvial y ferroviaria del Caribe colombiano en los siglos XIX y XX: el ferrocarril de Cartagena
Authors: Correa Restrepo Juan Santiago , Reyes Pérez Andrés Felipe
Published: July 2022

El presente documento examina la conexión ferroviaria para el comercio internacional del país por el puerto de Cartagena, en cuanto a su capacidad de situarlo como eje estructurador de la vida económica, política y social, no solo en el departamento de Bolívar, sino, en general, en la región Caribe en los siglos XIX y XX. Aborda el poco éxito del ferrocarril de Cartagena: las causas de este fenómeno y los diferentes problemas que enfrentó, especialmente la rivalidad con otros proyectos y alternativas similares. Se indaga, igualmente, por el papel que desempeñó el ferrocarril en la configuración de los movimientos sociales impulsados por trabajadores calificados, y su alcance e impacto en la historia regional y nacional. La investigación se apoyó principalmente en fuentes hemerográficas, sobre todo, en las consultadas en la hemeroteca de la Biblioteca Nacional de Bogotá, que proveyeron un rico archivo de prensa regional, particularmente de cartagenera, para la comprensión del periodo 1860-1950.

Published: July 2022

The incidence of oropharyngeal squamous cell carcinoma (OPSCC) especially human papillomavirus (HPV) associated type is increasing in trend despite reducing in other head and neck squamous cell carcinoma. Muffled voice, dysphagia, neck mass and pain over the throat are among the common presentations; however, health care professional should be aware of unusual presentation to avoid delay in management. We present a case of HPV-positive OPSCC with a rare presentation; progressive worsening of snoring for 6 months duration. Patient sougth medical attention at the some of private clinics for the past 2 months, however, was told to have a normal tonsillar enlargement. Subsequently, patient was referred to our center with impression of obstructive sleep apnea. We highlight the important of early referral to appropriate center and otorhinolaryngology for assessment in cases presented with worsening snoring.
Bilateral Mature Ovarian Teratoma with Torsion in a Premenarchal Girl
Authors: Lešková Jana , Kříž Jaroslav Thierry , Štichhauer Radek
Published: July 2022

Mature cystic teratoma is the most common type of ovarian tumor in children. Adnexal torsion is the main complication of mature ovarian teratoma. The synchronous bilateral incidence of mature cystic teratoma in premenarchal girls is known to be rare. However, the incidence of adnexal torsion is higher in young girls. A 10-year-old girl presenting with acute abdomen was managed by emergency laparotomy. Bilateral mature ovarian teratoma with adnexal torsion of the right ovary was found. The right ovarian tissue was not viable due to torsion and an oophorectomy was necessary. Cystectomy with preservation of the ovarian tissue of the left ovary was performed. Histopathological diagnosis was bilateral synchronous mature teratoma with necrosis of the right adnexa. Although the risk of malignancy of torsed ovaries and mature teratomas in premenarchal girls is low, their removal is recommended to prevent adnexal torsion. Decision between ovarian tissue sparing surgery or oophorectomy depends on the risk of malignancy, fertility preservation and the avoidance of early menopause.

Bu çalışmada finansallaşma olgusu, dijital verinin metalaştığı kapitalizmin güncel biçimlerinden biri olan platform kapitalizmi çerçevesinde tartışılmaktadır. Finansallaşma, literatürde çoğunlukla yeni bir birikim rejimi, şirket yönetimlerinin amaç fonksiyonlarının değişmesi ve gündelik hayatın finansallaşması şeklinde üç farklı yaklaşımla ele alınmaktadır. Bu makalede, bu sınıflandırmaya dördüncü bir ayrım eklemeyi öneriyoruz: dijital finansallaşma. Dijital finansallaşma, bireylerin dijital verileri aracılığıyla gözetimi ve bu yolla kâr elde edilmesine olanak sağlayan melez bir alan yaratmak için dijital ve finansal alanların bütünleşmesini ifade eder. Çalışmanın amacı geleneksel finansallaşma argümanlarının, dijital finansallaşma bağlamında geçerliliğini sorgulamak ve finansallaşma analizini dijital veriyi kapsayacak biçimde genişletmektir. Çalışmanın bulgularına göre, BigTech ve FinTech şirketleri bütünleşik bir dijital-finansal alan oluşturarak dijital veriyi finansallaştırmaktadır. Veriye dayalı finansal kapsayıcılık faaliyetleri, finansın demokratikleşmesi söylemi altında, finansal ürün kullanımını dünya nüfusunun büyük bir kesimine yaymayı amaçlar. Sonuç olarak dijital finansallaşma “bankasız nüfus” dahil olmak üzere geniş kesimlere platformlar aracılığıyla erişim sağlayarak finansallaşmayı genişletmekte ve derinleştirmektedir. Platform kapitalizmi altında geliştirilen iş modellerinin finansallaşma bağlantıları dikkate alındığında, dijital veriye dayalı yeni “sömürü” mekanizmaları oluşabilir
Application of a modular topology optimization framework to an aerospace bracket design
Authors: Gökdağ İstemihan , Acar Erdem
Published: July 2022

In aerospace industry, optimizing designs has become inevitable in terms of weight and performance requirements. Topology optimization is the most suitable optimization type for use in the conceptual design phase. Even though academic topology optimization algorithms have a modular structure (open to development), they are often useable for a regular design domain. Alternatively, commercial topology optimization software products, on the other hand, are very useful in terms of their solution speed, accuracy, and ability to handle complex or irregular design domains. However, the user is restricted with the optimization algorithms available in the software, and these software do not usually have a modular structure. In this study, a modular topology optimization framework that combines useful features of the academic codes (e.g., modularity) and the commercial software tools (e.g., capability of easily handling complex design domains) is developed. The developed framework is tested on two popular academic topology optimization problems, followed by aerospace bracket design problem. It is observed that the proposed framework usually provides lower objective function values and converges to the optimum result in fewer iterations than the Altair Optistruct topology optimization software.
Bad Fathers, Spurious Daughters, and Fratricidal Projects
Authors: Troester Patrick T.
Published: July 2022

This article examines violence in the eastern U.S.-Mexico borderlands during the U.S.-Mexico War. By analyzing and comparing military mobilization, local experiences of violence, and gendered national ideologies on each side, it explores how the conflict called the Mexican and U.S. nation-states into being, both in this region and beyond. Whether actively participating or not, diverse borderlands people experienced the war primarily within the gendered context of pre-existing local networks of kinship and community. Alongside ideologies that portrayed the nation-state as a fictive national family, such local ties powerfully structured the ways in which borderlanders reckoned their places within the emerging U.S. and Mexican nation-states. In these ways, they actively joined in creating both state power and the meanings of nationalism at the grassroots level.
Zika virus alters centrosome organization to suppress the innate immune response
Authors: Kodani Andrew , Knopp Kristeene A , Di Lullo Elizabeth , Retallack Hanna , Kriegstein Arnold R , DeRisi Joseph L , Reiter Jeremy F
Published: July 2022

Zika virus (ZIKV) is a flavivirus transmitted via mosquitoes and sex to cause congenital neurodevelopmental defects, including microcephaly. Inherited forms of microcephaly (MCPH) are associated with disrupted centrosome organization. Similarly, we found that ZIKV infection disrupted centrosome organization. ZIKV infection disrupted the organization of centrosomal proteins including CEP63, a MCPH‐associated protein. The ZIKV nonstructural protein NS3 bound CEP63, and expression of NS3 was sufficient to alter centrosome architecture and CEP63 localization. Loss of CEP63 suppressed ZIKV‐induced centrosome disorganization, indicating that ZIKV requires CEP63 to disrupt centrosome organization. ZIKV infection or CEP63 loss decreased the centrosomal localization and stability of TANK‐binding kinase 1 (TBK1), a regulator of the innate immune response. ZIKV infection also increased the centrosomal accumulation of the CEP63 interactor DTX4, a ubiquitin ligase that degrades TBK1. Therefore, we propose that ZIKV disrupts CEP63 function to increase centrosomal DTX4 localization and destabilization of TBK1, thereby tempering the innate immune response.
When does development come? Transformations and uncertainty in a small rural community in Morocco
Authors:   Universidad de Valencia, Berlanga María Jesús , Lacomba Joan ,   Universidad de Valencia
Published: July 2022

Development has always been a controversial issue, with multiple views surrounding it. However, theoretical discussions have rarely been transferred to the empirical field and have been confronted with the life experience of populations. The objective of this article is to delve into the implications of the implementation of development from the case of a small community located in the central mountains of Morocco. Our basic hypothesis is that understanding development remains complex, while requiring the integration of the views of different actors and the use of alternative approaches. From the continuous contact over time with the community, both on the field and from distance, we show the transformations that have taken place in it and the dilemmas that it still faces after two decades of development.
Trends and challenges in social work. A view from the Portuguese reality
Authors:   Universidade Lusófona de Lisboa, Marques Jacqueline
Published: July 2022

This article is a theoretical reflection on current trends and challenges in social work. Based on a reflective reading of various authors and the author's analysis of social work in the last decade, six trends are presented: the first describes the current overvaluation of the individual dimension to the detriment of the collective dimension, with the consequent moralisation of social problems; the 2nd explicitly states the change in the notion of law with the modification of law into law-obligation; the 3rd presents the transformation of rights into non-universal palliative actions, through the transfer of competences from the central state to the local state, the market and civil society; The 4th demonstrates the transformation of the universal character of rights through the targeting of social policies; the 5th exposes the trend towards the increasing instrumentalisation and technification of social work, which imposes an instrumental rationality and a secondaryisation of the relational function of the profession; the 6th trend is both a result and a cause of the others: the abandonment of the collective and political character. To address these trends, we present 14 challenges that seek to adopt a transformative vision of social work, based on a collective project that articulates all the dimensions of the profession and develops emancipatory actions that respect the intrinsic value of the dignity of all human beings, respect for diversity and the defence of human rights and social justice.
Physiological interindividual variability in endogenous estradiol concentration does not influence adipose tissue and hepatic lipid kinetics in women
Authors: Magkos Faidon , Fabbrini Elisa , Patterson Bruce W , Mittendorfer Bettina , Klein Samuel
Published: July 2022

Objective

Increased triglyceride (TG) and apolipoprotein B-100 (apoB-100) concentrations in plasma are important risk factors for cardiovascular disease in women. Administration of some estrogen preparations raises plasma TG and apoB-100 concentrations by increasing hepatic very low-density lipoprotein (VLDL) TG and apoB-100 secretion rates. However, the influence of physiological variation in endogenous estradiol on VLDL-TG and VLDL-apoB-100 metabolism and on free fatty acid (FFA) release into plasma (the major source of fatty acids for VLDL-TG production) is not known.

Design and methods

We measured basal VLDL-TG, VLDL-apoB-100, and plasma FFA kinetics by using stable isotopically labeled tracers in 36 eumenorrheic, premenopausal women (age: 33 ± 2 years, BMI: 31 ± 1 kg/m2; mean ± s.e.m.) during the follicular phase of the menstrual cycle; participants were divided into two groups based on low (n = 18) or high (n = 18) plasma estradiol concentrations (defined as below or above the median value of 140 pmol/L in the whole group).

Results

Mean plasma estradiol concentration was >3-fold higher in the high-estradiol than in the low-estradiol group (299 ± 37 and 96 ± 7 pmol/L, P < 0.001); there was no difference in plasma progesterone concentrations between the two groups (P = 0.976). There were no significant differences in plasma FFA concentration, FFA rate of appearance in plasma, VLDL-TG and VLDL-apoB-100 concentrations, hepatic VLDL-TG and VLDL-apoB-100 secretion rates, VLDL-TG and VLDL-apoB-100 plasma clearance rates, and mean residence times (all P ≥ 0.45). No significant associations were found between plasma estradiol concentration and FFA, VLDL-TG, and VLDL-apoB-100 concentrations and kinetics (all P > 0.19).

Conclusions

Plasma estradiol concentration is not an important correlate of basal plasma FFA, VLDL-TG, and VLDL-apoB-100 kinetics in premenopausal women.
Controversias del margen. Un repaso por el cine argentino de la marginalidad en las últimas décadas
Authors: Pisciottano Lucia
Published: July 2022

En las últimas tres décadas, el cine argentino ha sufrido grandes transformaciones, desde su casi desaparición en 1994, pasando por un período de renovación, una posterior ampliación de sus márgenes estéticos y un aumento de su heterogeneidad -que se dio hasta 2015-, cuando se presentó un nuevo desafío para la producción audiovisual nacional con el retorno de las políticas económicas neoliberales y la posterior llegada de una pandemia que paralizó casi de lleno la realización de obras audiovisuales. En este artículo realizaremos un repaso general por estas etapas, utilizando el Cine de la Marginalidad como eje articulador del período, entendiendo la importancia nodal que el mismo tiene a lo largo de las últimas décadas.

El proceso de convergencia digital ha modificado los distintos medios e industrias culturales de forma global. Sin embargo, las características locales presentan rasgos particulares que difieren en cada región. Podríamos pensar que, en Argentina, este proceso permitió en un primer momento, la ampliación de los márgenes estéticos pero que, a medida que se instalaron las nuevas formas del audiovisual en el siglo XXI, cada vez queda menos lugar para un cine autoral, independiente o vanguardista. Bajo esta premisa, el artículo indagará en el avance de la industria audiovisual en Argentina, para este cine que había resurgido desde los márgenes.

Entre Francia y los Habsburgo. El gobierno de la Compañía de Jesús y las relaciones internacionales (1670-1694)
Authors: Lozano Navarro Julián J.
Published: July 2022

Entre 1670 y 1694, coincidiendo con los generalatos de Oliva, Noyelle y González, la Compañía de Jesús vio amenazada su integridad y autonomía en al menos tres ocasiones. El presente trabajo se configura como una aproximación –desde el punto de vista político y de las relaciones internacionales– a las vicisitudes experimentadas por el gobierno romano de la Compañía, atrapado en la colisión de las dos grandes estrategias hegemónicas de la época: la de la Francia de Luis XIV y la de la Casa de Austria. Potencias católicas que percibían a la Compañía como una importante herramienta a controlar y utilizar en aras de la consecución de sus respectivas conveniencias políticas. Una realidad que hizo a los generales, pero también a otros jesuitas, moverse en un equilibrio inestable que afectaba a cuestiones de gran calado. Como a la obediencia de los hijos de san Ignacio al papa y a su general; a la continua injerencia de los soberanos seculares; a la toma de partido de muchos jesuitas como nacionales de un territorio; o a su opinión en los debates por cuestiones doctrinales que se experimentaban en el seno de la Orden.
Los primeros años de Agustín de Castro, SJ, en la corte (1629-1632)
Authors: Pizarro Llorente Henar
Published: July 2022

El jesuita Agustín de Castro (1589-1671) ocupó la cátedra de Política de los Reales Estudios en 1629. Unió a esta actividad su labor como predicador real desde 1635, convirtiéndose en una de las figuras más destacadas en la oposición política al Conde Duque de Olivares. La polémica estuvo unida a su trayectoria, en la que también destacó como calificador del Santo Oficio. Su colaboración con el Inquisidor General Antonio Zapata y Cisneros, marcada por el antisemitismo, tuvo una especial relevancia durante los primeros años de estancia en la Corte, que fueron decisivos para su evolución posterior.
Cell-derived Giant Membrane Vesicles Enclosing the Anthracycline Anti-Cancer Drug Doxorubicin and their Cytotoxicity
Authors: Hisato Saitoh , Saya Okada
Published: July 2022

Although giant membrane vesicles prepared from paraformaldehyde-treated mammalian cells have been used to elucidate lipid and protein dynamics on the cell surface, there are few studies that have used them as a tool to deliver drugs to cells. Here we found that anti-cancer drug doxorubicin (Dox) was efficiently incorporated into and stably retained in giant membrane vesicles prepared from HeLa human cervical cancer cells. Intriguingly, coincubation of Dox-enclosed giant membrane vesicles with human pancreatic cancer-derived PK-59 and gastric cancer-derived KE-39 cells led to cell death. Microscopic observation of vesicle-docked cells revealed that docking of at least one to a few Dox-enclosed giant vesicles on the cellular cortex was sufficient to induce cell death, suggesting applicability of cell-derived giant membrane vesicles as an efficient drug delivery vector in cultured cell systems.

In contrast to objective observations, I recorded during my site visits a panoply of overheard conversations, drawings, remarks, puns, encounters, temperatures, and colours. These and other elements comprised my experiences in each site, and I wanted to represent their gist and connotations through multiple forms of expression. This approach aligns with arts-informed research methodology that celebrates complexity and shared meaning-making with engaged scholarship. I used these notes to produce for each site a written vignette, to introduce and reacquaint others with that place; two of these vignettes appear in the following report. In translating what I came to call my “feel’d,” not “field,” notes into these written pieces, I gleaned new understandings about scribbling and scrawling expressive, affective feel’d notes. I found that engagement enriched my research process, and also fostered a greater awareness of place meanings. I recognize that transformed notetaking has a bearing on understanding, research process, people/communities, and places, and offers methodological insights that carry out and further engaged scholarship knowledge.
Three Examples of Engagement through Photovoice

Addressing the complex challenges of today’s world requires our collective creative capacity. As such, arts-based methods which promote creativity are increasingly important means of engaging people in the issues that matter most to them. This article focuses on one arts-based method, Photovoice, which is a “process by which people can identify, represent, and enhance their community through a specific photographic technique” (Wang & Burris, 1997, p. 369) where participants take photos in response to a question or topic of inquiry. To explore this engagement method, we draw from the methodological insights gleaned from three Master’s Arts in Leadership capstone projects that employed Photovoice (or variations thereof) as one method of inquiry.

The article is organized as follows: We begin by reviewing Photovoice as a research and engagement method and then summarize the three projects, which occurred in two nonprofit organizations and one public sector institution. In the discussion, we then compare and contrast the methodological insights emerging from these projects, including the extent to which each project: (a) enabled workers at various levels of organizational hierarchies to share their voices; (b) required careful attention to ethics; and (c) generated relationships among participants. As this is a methodological paper, our emphasis here is to highlight the process and impact of using Photovoice as a method rather than sharing each of the study findings and conclusions. In each example, Photovoice as both a research and engagement method enabled participants to play a leadership role in participatory engagement, thus deemphasizing top-down decision-making and promoting more integrated approaches to research and leadership as engagement.
The arts in individual transformation: examples from the recycling social movement in São Paulo, Brazil
Authors: De Oliveira Jayme Bruno , Heringer Rebeca
Published: July 2022

How does individual transformation unfold within social movement learning (SML), a territory that mainly embodies learning as a collective practice? What are the roles of visual arts in mediating such transformation? We answer these questions by exploring discourses that emerged during visual arts workshops facilitated with members of the recycling social movement in São Paulo, Brazil. To do so, we intertwine arts-based research, SML, and transformative learning theories informed by Vygotskian’s cognitive development approach as an analytical tool. Findings suggest that during the art-making process, recyclers construct their visual thought, which enables their empowerment and agency as fundamental mediators of individual transformation.

This paper describes the compensation method for atmospheric attenuation of laser radiation, which can be implemented in active electro-optical systems with pre-detector dynamic spectral processing of optical signals. In these electro-optical systems, the spectral flux of sensing radiation is formed using multispectral laser signals based on a priori information about the spectral reflectance of the target and background. The sensing signal formed in this way ensures maximum suppression of the background signal at the output of system with minimal attenuation of the target signal. The influence of atmospheric radiation attenuation on operation of an active electro-optical system with dynamic spectral processing has been analyzed. It has been shown that the laser radiation attenuation in the atmosphere significantly affects the efficiency of dynamic spectral processing of optical signals (leads to a decrease in the target image contrast). The developed compensation method for atmospheric attenuation of radiation in active electro-optical systems with dynamic spectral processing is based on the fact that the spectral intensity of the sensing radiation is formed not only on the basis of a priori data on spectral characteristics of the target and background, but also takes into account the spectral transmittance of the optical radiation propagation medium.
On the Features of Ideal Bose-Gas Thermodynamic Prop-erties at a Finite Particle Number
Authors: Bugrij A.I. , Loktev V.M.
Published: July 2022

The paper is devoted to the theory of an ideal Bose-gas with a finite number N of particles. The exact expressions for the partition functions and occupation numbers of the model in the grand canonical, canonical, and microcanonical ensembles are found. From the calculations, it is followed that, oppositely to the accepted opinion that the chemical potential μ of an ideal Bose-gas is only negative, it can take values in the range −∞ < μ < ∞. The asymptotic expressions (in the case N ≫ 1) for the partition functions and occupation numbers for all above-mentioned thermodynamic ensembles are also evaluated.
Solitary and periodic wave solutions of the loaded modified Benjamin-Bona-Mahony equation via the functional variable method
Authors: Babajanov B. , Abdikarimov F.
Published: July 2022

In this article, we established new travelling wave solutions for the loaded Benjamin-Bona-Mahony and the loaded modified Benjamin-Bona-Mahony equation by the functional variable method. The performance of this method is reliable and effective and gives the exact solitary wave solutions and periodic wave solutions. All solutions of these equations have been examined and three dimensional graphics of the obtained solutions have been drawn by using the Matlab program. We get some traveling wave solutions, which are expressed by the hyperbolic functions and trigonometric functions. This method is effective to find exact solutions of many other similar equations.
Two sharp inequalities for operators in a Hilbert space
Authors: Kriachko N.O.
Published: July 2022

In this paper we obtained generalisations of the L. V. Taikov’s and N. Ainulloev’s sharp inequalities, which estimate a norm of function's first-order derivative (L. V. Taikov) and a norm of function's second-order derivative (N. Ainulloev) via the modulus of continuity or the modulus of smoothness of the function itself and the modulus of continuity or the modulus of smoothness of the function's second-order derivative. The generalisations are obtained on the power of unbounded self-adjoint operators which act in a Hilbert space. The moduli of continuity or smoothness are defined by a strongly continuous group of unitary operators.

The objective of this research was to determine some of the sociodemographic and academic characteristics of the students who entered the Dentistry career in the period 2007 to 2014. Data was collected from 673 student files. The variables considered were sex, admission age, marital status, children, nationality, place of origin, high school of origin, and admission exam score. The data was obtained from the database of the Student Applications System, the physical files, and the Supreme Electoral Tribunal of Costa Rica. Descriptive statistics were performed, establishing the absolute and relative frequency of the variables. The Mann-Whitney test was used to determine if there were statistically significant differences between the admission exam and the established sociodemographic variables (p<0,05, IC 95%). 68,4% of the students are female. The average age was 18.4 years (SD=2,41). 99,0% of the students are from Costa Rica. 99,3% were single and only 0,9% had children. The largest number of students entered through an admission exam (78.9%) and 50.7% studied at a public high school. Regarding the address, 77.9% of the subjects resided in the Greater Metropolitan Area. The average grade of the admission exam was 613,8 (SD=49,95). There was a statistically significant difference between the entrance exam grade and the different types of high schools of origin. The group of students who entered to train as Dentists at the University of Costa Rica from 2007 to 2014 was a population with an average age of entry of 18,4 years, Costa Rican, predominantly female, single, without children, from geographic areas within the Greater Metropolitan Area (GMA), graduated from public schools with an average admission exam grade of 612,2.
