Authors: Stepanov Oleg , Pechegin Denis , Dolova Mariia , Trefilov Alexander
Published: May 2020

The introduction of digital technologies has an impact on various aspects of criminaljurisdictional activity, optimizes the decision-making process based on data collection, coordination of actions of law enforcement officers, increases the effectiveness of their actions by minimizing the human factor in the process of legal decision-making through the use of the potential of artificial neural networks. On the basis of dialectical-materialist method and special legal research methods it is noted that the relationship between the concepts of “digital justice” and “justice” can be represented in the form of basic characteristics of the development of the same socially significant process, a key element of which is the use of robotic programs that simplify and accelerate human activities. It is pointed out that in the process of building in our society a fair legal basis of statehood, moral and legal culture as an integral attribute and a distinctive feature of the progressive development of the state is becoming increasingly important and of practical importance. The purpose of the article is to analyse the approaches and problems related to the Justice within the modern digital developments.
From Nuremberg to the Hague and beyond: International criminal law in courts: Court of Bosnia And Herzegovina as an example
Authors: Dauster Manfred
Published: May 2020

International criminal law in courts will seize our interest forever. Adjudication of international criminal law violations have to happen in and by courts. They may be national courts; they also may be international (permanent or ad hoc) courts. Not to forget: It is also proposed to prosecute internationally active terrorists by international courts. It is worthwhile to take a short look at the historical development of such discussions. The so-called International (Legal) Community has discussed all forms of international criminal jurisdiction and will keep on discussing. In Bosnia and Herzegovina once the so-called internationals started an experiment with the (national) Court of Bosnia and Herzegovina, which in its nutshell was an administrative court that then was turned into a hybrid court predominantly for war crimes (and other serious felonies). As such a hybrid institution the Court was successful. International judges have left and the court became a purely national institution again. The short hybrid history of this court in a corner of the Western Balkans is worthwhile to be studied shortly.
The Right to physical and mental immunity in the light of the new constitution of the Republic of Armenia and modern challenges in this field in Armenia
Authors: Tonoyan Narine
Published: May 2020

The Constitution of the Republic of Armenia (RA) for the first time envisaged the right to physical and mental immunity (in the former edition of personal immunity) in 2015. According to Article 25(1) of the RA Constitution, everyone shall have the right to physical and mental integrity. That right may be restricted only by law, for the purpose of state security, preventing or disclosing crimes, protecting public order, health and morals or the basic rights and freedoms of others. The bodily rights of the person, including the right to physical and mental immunity, are recognized in professional literature as somatic rights that have become a subject of vigorous debates as a new generation of human rights. In general, human somatic (bodily) rights constitute a wholeness, which includes: the right to life; the right to die or the right to choose a way of giving up one’s life (right to suicide, right to use euthanasia), etc. Current report in the light of the RA Constitution report discuss some of important issues in this field: eugenic experiments, medical intervention, organs and tissues transplantation, etc.

Authors: Töz Emrah , Özcan Aykut
Published: May 2020

Objective: The aim of this study was to evaluate the trend in uptake of salpingectomy at the time of vaginal hysterectomy after the Clinical Practice Statement of Society for Gynecologic Oncology and to assess the risk of operative/postoperative complications associated with salpingectomy during vaginal hysterectomy.

Material and Methods: Patients who underwent vaginal hysterectomy or vaginal hysterectomy with salpingectomy for uterine prolapsus between January 2010 and January 2018 were analysed. We divided the patients into two groups to see the change in the rate of opportunistic salpingectomy after a systemwide practice recommendation was issued. Group 1 consist of patients who were operated between 2010-2014, before recommendation of the Society of Gynecologic Oncology that favour salpingectomy and Group 2 consist of patients operated after that.

Results: From January 2010 to January 2018, a total of 1224 vaginal hysterectomies were performed. A total of 808 patients under 60 years old were included in the study. There was no difference in operating time, the median estimated blood loss, intraoperative complication and postoperative complication by the performance of salpingectomy (P>0.05). When we examine the changes in the rate of salpingectomy year by year, from 2014, the salpingectomy rates increased, being 4 % in 2013, 7 % in 2015, and 8 % in 2017 onward.

Conclusion: We report an increase in the rate of salpingectomy during vaginal hysterectomies from 3 % to 7.2 % after the recommendation of the Society of Gynecologic Oncology that favour salpingectomy but this increase is not as great as the increase during laparoscopic or abdominal hysterectomies.

Introduction: This study aims to evaluate the pre- and postoperative outcomes of myomas operated in a tertiary clinic.

Method: We retrospectively evaluated data from a total of 378 cases operated for myomas between January 2014 and December 2018 in the Dicle University Medical Faculty Obstetrics and Gynecology Clinic.  

Results: There were 169 cases of abdominal myomectomy (44.7%), 156 cases of total abdominal hysterectomy (41.3%), 15 cases of laparoscopic myomectomy (4%), 13 cases of total laparoscopic hysterectomy (3.4%), 12 cases of myomectomy during cesarean delivery (3.2%), 9 cases of hysteroscopic myomectomy (2.4%), and 4 cases of vaginal myomectomy (1.1%). Pathology results revealed 341 cases of leiomyoma (88.2%), 32 cases of concomitant leiomyoma and adenomyosis (8.4%), and 13 cases of STUMP (3.3%). There were 5 cases of intraoperative bowel injury, 1 case of bladder injury, and 1 case of postoperative wound infection.

Conclusion: Myomas can be surgically treated with satisfactory outcomes and low complication rates. The preferred surgical treatment will majorly depend on the patient's fertility expectations.

Authors: Balikoglu Meric , Bayraktar Burak , Akar Mert Mevlüt
Published: May 2020

Ectopic pregnancy(EP) treatment success in a single dose methotrexate(MTX) regimen is decided by more than 15% β chorionic gonadotropin reduction in the 4th and 7th days after administration of 50mg/m² of medication.  In our study , it was aimed whether the EP mass size less than 40mm detected by ultrasonography and the adnexal side on which it was located had an effect on the success of medical treatment.

82 patients who treated with MTX included in the study were divided into two groups as those with a single dose of methotrexate success and those without (n:67 vs n:15). The groups were compared in terms of age, parity, size of adnexal mass detected on ultrasonography, and the side of ectopic pregnancy.

The parity rates and the age of patients were similar in both groups(p = 0.615, p = 0.742). Although the average adnexal mass size was found to be higher in the patient group those single dose MTX treatment was not successful, there was no statistically significant difference(p = 0.098). Ectopic pregnancy was frequently observed on the right side in the group in which the medical treatment was successful(66 % vs 33%).

The effect of ectopic pregnancy mass size on medical treatment prediction was investigated in cases with mass size less than 40mm. Ectopic pregnancy mass size, even if it is below 40 mm, may not indicate the medical treatment success.
Laparoscopic removal of migrated intrauterine device located on sigmoid colon, case report and literature review
Authors: Öner Öznur , Özcan Aykut , Çankaya Zeynep
Published: May 2020

The extrauterine migration of an intrauterine device (IUD) can be life-threatening and may require emergent surgical intervention and treatment. A case report where an ectopic IUD located on sigmoid colon within peritoneal cavity in a 40-year-old multigravida was successfully removed by laparoscopy is described. Although the practicality and success of this method depends on the position and location of the ectopic IUD and on the extent to which the device is imbedded, this case suggests that removal of the migrated IUD from the peritoneal cavity is an additional possibility for use of the laparoscope.

Published: May 2020

Objective: The aim of this study is to evaluate the obstetric and neonatal outcomes of pregnant women delivering large for gestational age (LGA) infants.

Material and Methods: A total of 399 pregnant women giving birth to LGA infants in the Gynecology and Obstetrics Department of Dicle University Medical Faculty Hospital between January 2014 and December 2018 were included in this retrospective study. Demographic features, pregnancy and infant data, delivery type (vaginal delivery/cesarean delivery), and patients’ indications for cesarean section were assessed.

Results: The mean age of the patients was 32.34±6.63, their gravida was 5.16±2.65 and parity was 3.55±2.36. The mean gestational week was 37.12±2.840 weeks and the mean birth weight was 3922.46±643.546 g. Of all patients, diabetes was detected in 28.5%, polyhydramnios in 11.3%, placental invasion anomaly in 4%, and preeclampsia in 9%. While 83.7% (334) of the patients underwent cesarean section, the remaining 16.3% (65) underwent normal delivery. 3.25% (13) of the patients developed complications during delivery. The rate of fetal anomaly was 11.7% (47) in existing pregnancies while the rate of fetal death was 5.01% (20).

Conclusion: A cesarean delivery was performed in the majority of pregnant women with a suspected LGA infant. This group of patients exhibited a very high rate of gestational diabetes mellitus and diabetes mellitus. Existing pregnancies constitute a specifical pregnancy population that should be taken into consideration regarding probable complications and problems with the infant.

Authors: Turgay Batuhan , KANMAZ Ahkam Göksel
Published: May 2020

Objective: To compare the prenatal, neonatal and postnatal complications of macrosomic deliveries in pregnancies with GDM (gestational diabetes mellitus) and non gestational diabetes mellitus. 

Material and Methods: The medical records of 42034 patients who made delivery in a tertiary hospital between 2014 and 2017 were enrolled retrospectively.  A total of 2102 patients who made delivery a newborn more than 4000 gr were accepted as macrosomia and included in the study. These patients were divided into two groups as pregnancy with GDM and no GDM so prenatal, birth and neonatal outcomes and complications of these groups were compared. A P value of <0.05 was considered statistically significant.

Results: 258 women with GDM and 1844 women with no GDM were included in this study. Patients who were in GDM group were younger than the patients in no GDM group with statistically significant (p<0.001). Preeclampsia, ceserean delivery and primary ceserean rate were higher in the GDM group with statistically significant (p<0.001). The mean birth week was lower significantly in the GDM group and mean newborn birth weight of GDM group was higher compared with no GDM group (p<0.001 and p<0.001, respectively). The rate of  necessity of newborn intensive care unit hospitalization and shoulder dystocia were higher in the GDM group.

Conclusion: Macrosomic pregnancies with GDM have some poor obstetrics and neonatal outcomes compared with macrosomic pregnancies with no GDM. On the other hand, it should be kept in mind that macrosomia can be occured with non-complicated pregnancy and obstetrician should consider the related complications.

Authors: Saçkıran Latife Buket , Beyan Emrah , Özeren Mehmet
Published: May 2020

Objective: The aim of this study was to investigate the success of ultrasound in the diagnosis of adnexal torsion before surgery and to define its histological diagnosis and results in different age periods.

Material and Methods: This study was carried out with a retrospective examination of 130 patients clinically suspected as adnexal torsion between January 2008 and May 2012. The success of sonography in the diagnosis of adnexal torsion was investigated by diagnostic tests. 70 cases confirmed by surgery were divided into 3 groups. Children and adolescents under 18 years of age were classified as Group 1, reproductive women Group 2 and postmenopausal women Group 3. In these 3 groups, mass size, type, histological diagnosis and outcome of adnexal torsion were defined.

Results: The sensitivity, specificity, and accuracy of ultrasound were 84.3%, 78.3%, and 81.5%, respectively. There were significant differences in the presence of ultrasonic hallmarks among the true positive, false positive, and false negative cases of adnexal torsion. Adnexal torsion was identified in 70 cases. The majority of cases were found to occur in the reproductive period (47 of 70). Teratoma was the most common histological diagnosis in children and adolescents, while normal ovary was in the reproductive period. In the postmenopausal period, the most common histological diagnosis was cystadenoma, but the malignant ovarian tumor was observed in 2 of 10 cases.

Conclusion: We conclude that ultrasonography performed by a specialized obstetrics and gynaecology ultrasound unit plays an important role in the preoperative diagnosis of adnexal torsion. Most adnexal torsions occurred in women of reproductive age, and the right side was dominant. The spectrum of histological diagnosis varied at different ages.

Published: May 2020

Enhancing students’ conceptual understanding and increasing student motivation to effectively participate in classroom discussions are important for instructors of mathematics. Web-based homework management systems provide alternatives to the traditional pen-and-paper based approaches. In addition, these tools facilitate the creation of a student-centered environment which allows instructors to assign work based on students' needs while using a variety of multimedia materials that can include animation, video, and/or audio in order to enhance student learning and facilitate student-instructor communications. These systems provide flexible instructional tools that not only offer students immediate feedback, but also track student performance. The goal of using these programs is to enhance student understanding and learning of different mathematical concepts. The purpose of this paper is to present students’ perceptions of the advantages and disadvantages of using two web-based homework management systems; MyMathLab and WebAssign. In addition, it sheds light on students’ habits of using these systems and their perception of the optimal number of attempts that should be allowed to complete the homework assignments.
Digitalization in Higher Education: A Qualitative Approach
Authors: Ugur Naciye Guliz
Published: May 2020

The increasing use of digital technology by young people has become a major concern in the 21st century. This access to technology has led to hot-button arguments surrounding the place of these technologies in our lives and the implications that they have for the future. The incorporation of multimodal and digital technologies in courses has been increasing, with documentaries, social media posts, and blogs host significant spaces for learning and coursework. These forms of knowledge and communication have started to become legitimized in the classroom setting, in addition to the traditional educational technologies such as lectures and textbooks. This paper explores the assumptions by instructors and students concerning why and how multimodal and digital technologies are incorporated into undergraduate classes by qualitative approach. Also, the actual experiences that students and instructors have in using these forms of media in an educational context are investigated via participant observation, in-depth review and open-ended questionnaire techniques along the research
Investigating Academicians’ Use of Tablet PC from the Perspectives of Human Computer Interaction and Technology Acceptance Model
Authors: Ozkale Abdullah , Koc Mustafa
Published: May 2020

This phenomenological study examines academicians’ beliefs and lived experiences of using tablet PC based on Human–Computer Interaction (HCI) and Technology Acceptance Model (TAM). Participants included 15 academic staff working in a university in Turkey. Data were collected through in–depth semi–structured interviews and subjected to content analysis. Main themes emerged from the data include reasons for purchasing tablet PC, usage patterns, professional and instructional implementation, comparison of tablet with other PCs, future expectations of tablets, and opinions about tablet experiences (performance increase, advantages, health issues). The results showed that academicians were satisfied with tablet PC and used it for presentation, social media, and routine tasks. However, they did not prefer it as a first PC option and they found it inadequate for all their works due to the limitation of subject-specific applications, incompatibility issues, difficulty in writing, and tendency to maintain previous PC usage habits. The findings did not indicate any reduction in the need and use of other PCs due to tablet ownership. Overall, this study supports the interaction of HCI components (user, tool, environment, tasks) and TAM components (perceived usefulness, perceived ease of use) and their effects on the adoption and use of a technological tool.

The data were collected through self-report scales from 196 university students of the three public universities. Cluster analysis was used to explore the profiles. Discriminant analysis was performed to identify a boundary among the students’ profiles based on personality, time management, gender and Facebook use of students. We found five different clusters based on information seeking behaviors of Facebook of the students. The results shows significant differences among these clusters. The result of discriminant analysis indicates that personality, time management and Facebook use are meaningful for discriminating information seeking behavior groups of students. The study reveals that students with high scores of information seeking behavior on Facebook have also high scores on openness to experience, agreeableness, conscientiousness and extroversion, time management skills. In spite of its limitations, the study certainly adds to our understanding of profiles of students using Facebook as a source of information.
AN APPLICATION OF THE METHOD OF WEIGHTED RESIDUALS TO THE BOUNDARY LAYER PROBLEMS
Authors: KARABULUT Utku Cem
Published: May 2020

Falkner-Skan equation is a third order non-linear boundary value problem which describes the laminar boundary layer flow developing on a plate. The strong non-linear characteristics of the problem, sensitivity of the equation to the initial conditions and the semi-infinite domain of the problem have attracted many researchers.In this paper, the method of weighted residuals is used to solve Falkner-Skan equations. The residuals are minimized by the least squares approach. The procedure is very simple and suitable for solving boundary layer problems. The main aim of this paper is to demonstrate the success of the proposed method. We observe that even the simplest approach with only one unknown provide quite accurate results for the velocity profile in the boundary layer. Additionally, better results with any desired accuracy can be obtained by increasing the number of unknown coefficient. Moreover, this method provides analytical solutions which are valid for whole domain.
Effects of Environmental Factors on Hydrogen Absorption and Sulfide Stress Cracking Susceptibility of Low Alloy Steel
Authors: Kobayashi Kenji , Omura Tomohiko , Fujimoto Shinji
Published: May 2020

In this study, the sulfide stress cracking (SSC) susceptibility of high-strength low alloy steels was investigated quantitatively. Double cantilever beam tests were used to evaluate the effects of environmental factors, namely pH, H2S partial pressure, and temperature, on the SSC. The corrosion rates and the absorbed diffusible hydrogen concentration were also determined. The critical stress intensity factor (KISSC), which signifies the SSC susceptibility, was mainly affected by the H2S partial pressure and the temperature. Even though the solution pH apparently affected the corrosion rate, the influence of pH on KISSC was small. Considering these results, the environmental contribution in each elementary process of the SSC phenomenon was discussed. The estimated local hydrogen concentration at the crack tip area, which clearly depends on H2S partial pressure and temperature, showed good correlation to the KISSC obtained in various sour conditions.
Liquid-water content and water distribution of wet snow using electrical monitoring

Published: May 2020

Abstract. Snow exists in a wide range of temperatures and around its melting point snow becomes a three-phase material. A better understanding of wet snow and the first starting point of water percolation in the seasonal snowpack is essential for snow pack stability, snow melt run-off and remote sensing. In order to induce and measure precisely the liquid water and the corresponding dielectric properties inside a snow sample, an experimental setup was developed. Using microwave heating at 18 kHz allows the use of dielectric properties of ice to enable heat to be dissipated homogeneously through the entire volume of snow. A desired liquid water content inside the snow sample could then be created and analysed in a micro-computer tomography. Based on the electrical monitoring a promising perspective for retrieving water content and water distribution in the snowpack is given. The heating process and extraction of water content are mainly dependent on the morphological properties of snow, the temperature and the liquid water content. The experimental observation can be divided in three different heating processes affecting the dielectric properties of snow for different densities: (1) dry snow heating process up to 0 °C indicating a temperature and snow structure dependency of the dielectric property of snow; (2) wet snow heating at stagnating temperature of 0 °C and the presence of uniformed distributed liquid water changes the dielectric properties. The presence of liquid water decreases the impedance of the snow sample until water starts to percolate; and (3) the start of water percolation is between 5–12 water volume fraction depending on the snow density and confirms the literature findings. The onset of water percolation initiated an inhomogeneity in snow and water distribution, strongly affecting the dielectric properties of the snow. These findings are pertinent to the interpretation of the snow melt run-off of spring snow. These laboratory measurements allow to find the narrow range of the starting point of water percolation in coarse-grained snow and to extract the corresponding dielectric properties which is important for remote sensing.

Non-economic Emigration Factors that Might be Pushing Citizens Out of Lithuania
Authors: Miežanskienė Ramunė
Published: May 2020

Based on a systematic and comprehensive review of literature on emigration, we identify potential non-economic push factors that might drive Lithuanian citizens to emigrate. Based on a random sample nationwide survey conducted in spring 2019 with Lithuanian citizens living in Lithuania, two categories have emerged as most critical non-economic drivers to lead to higher intention to emigrate: quality of working life and confidence in the future. Further research can add necessary nuance to understanding these factors while also experimenting with possible policy and project interventions that can reduce intent to emigrate and/or encourage return migration. This research is implemented under the project "The importance of non-economic factors to the emigration of the Lithuanian population", funded by the Research Council of Lithuania under the Programme "Improvement of researchers' qualification by implementing world-class R&D projects" (Agreement No. 09.3.3-LMT-K-712-01-170).
The Role of Campaigns in Law Enforcement
Authors: Habicht Jasper
Published: May 2020

Kampagnen sind in der Volksrepublik China ein etabliertes Mittel zur Durchsetzung von politischen und rechtlichen Zielen. Seit dem Beginn der Reform- und Öffnungspolitik hat sich das Land wirtschaftlich rapide entwickelt, was ein Grund ist sowohl für die stetige Weiterentwicklung des lokalen Rechtssystems als auch für die Attraktivität Chinas für ausländische Arbeitskräfte. Dieses Buch untersucht die Rolle von Kampagnen im Kontext des chinesischen Einwanderungsrechts, das im Jahr 2012 grundlegend reformiert worden ist. Es geht dabei der Frage nach, warum die Revision des Gesetzes zur Verwaltung der Ein- und Ausreise mit der verstärkten Durchführung von Kampagnen gegen illegale Einwanderung und illegale Beschäftigung von Ausländern einherging. Zu diesem Zweck untersucht dieses Buch sowohl den inneren Aufbau der Kampagnen als auch die Einbettung des aktuellen Einwanderungsrechts in den Kontext des chinesischen Verwaltungsrechts.
Ein aufgeschobenes Leben
Authors: Kraus Dita
Published: May 2020

Dita Kraus überlebte mehrere Konzentrationslager und baute sich in Israel ein neues Leben auf.

Dita Kraus, geboren 1929 in Prag, wächst als einziges Kind einer jüdischen Familie auf. Ihre unbeschwerte Kindheit schildert sie mit Witz und Wehmut. 1942 wird sie mit ihren Eltern zunächst nach Theresienstadt, dann nach Auschwitz deportiert, wo ihr Vater stirbt. Schließlich gelangt sie mit ihrer Mutter über Außenlager des Konzentrationslagers Neuengamme in das KZ Bergen-Belsen, wo beide am 15. April 1945 befreit werden. Kurz danach stirbt die Mutter.
Dita kehrt allein nach Prag zurück. 1949 entschließt sie sich, mit ihrer jungen Familie nach Israel zu emigrieren. Anschaulich und detailliert beschreibt sie, wie sie sich - wie viele andere Holocaust-Überlebende in Israel auch - unter schwierigsten Bedingungen eine neue Existenz aufbauen. Sie bleibt von Schicksalsschlägen nicht verschont und muss den Tod von zwei ihrer drei Kinder erleben. Gleichwohl schafft sie es, sich ihren Lebensmut zu bewahren.
Seit Anfang der 1990er Jahre berichtet sie als Zeitzeugin über ihre bewegte Lebensgeschichte. In ihren Memoiren erinnert sie sich an die Menschen und die Stationen ihres Lebens und schaut zurück auf neunzig Jahre gelebte jüdische Geschichte.
Descriptive Epidemiology of Traumatic Injuries During the First Lockdown Period of COVID-19 Crisis in Iran: A Multicenter Study
Authors: Khak Mohammad , Shakiba Saeed , Rabie Hamid , Naseramini Reza , Nabian Mohammad Hossein
Published: May 2020

Background: The study of alterations in the epidemiological pattern of traumatic injuries during the COVID-19 crisis can provide estimates in the planning of healthcare resources. In a prospective epidemiological study during the first 45 days of lockdown legislation in Iran and by comparing the results with previously published large population-based studies in Iran, we sought changes in the epidemiology of traumas. Methods: Data were obtained prospectively from the orthopedic emergency departments of two tertiary orthopedic trauma centers in Iran form Feb 20 to Apr 3 2020 for 45 days. Both centers were active in giving care for COVID-19 patients, and they were major referral orthopedic trauma centers. Results: A total of 628 patients with a mean age of 38.9 ± 19.9 (range 1 to 96) years consisting of 640 limb injuries were recruited. There were 387 (60.5%) fractures, 176 (27.5%) lacerations, and only 13 (2%) ligamentous injuries due to sports activities. Low-energy trauma was the most common mechanism of injury (38.3%), and its rate was specifically high as the mechanism of injury among women (69 %). In men, sharp injuries had the highest frequency (33%). Sharp injuries and blunt trauma during labor were 6.6 times and 19.5 times more prevalent in men, respectively. Most injuries were seen in 21 - 40-year-old patients. Distal radius/ulna fracture was the most common site of fracture. There were 233 (36.4%) patients with self-discharge. Conclusions: There were important epidemiological changes during the COVID-19 crisis in trauma patients. The cessation of sports activities resulted in a reduction in ligamentous injuries of sports origin. Women better implemented the stay-at-home strategies shown by a sudden increase in the men to women ratio of risk-taking traumatic injuries. The decreased number of patients with soft-tissue injuries and a high rate of self-discharge must inform the authorities of the fear of in-hospital contamination.
Comparative fecundity of the imperiled crayfishFaxonius quadruncusCreaser and invasive crayfishFaxonius hylas(Faxon) in the St. Francis River drainage of Missouri, USA

Knowledge of crayfish species’ life history traits is vital to their conservation and management. Fecundity is one trait that is a likely indicator of extinction risk and potential invasiveness. Fecundity-related data are lacking for the imperiled St. Francis River crayfish (Faxonius quadruncus) that is declining in the presence of the invasive woodland crayfish (Faxonius hylas). We sampled ovigerous females in three populations each of F. quadruncus and invasive F. hylas in Missouri (USA) Ozarks streams during April 2014 to compare fecundity and egg size between the two species. Differences in fecundity-related traits existed among populations of F. quadruncus, but no differences existed between the species. Results for both species were well within the ranges reported for other Faxonius species, but likely reflect small sample sizes rather than the entirety of each species. We also investigated the utility of field versus laboratory fecundity measures and found that field egg counts on live females varied among observers and also underestimated laboratory counts by an average of 22%. We provide a linear equation that can serve as a correction adjustment for field pleopodal fecundity estimates on live females to avoid specimen sacrifice during future monitoring of these species.
An observation of the use of devil crayfish (Cambarus cf. diogenes) burrows as brooding habitat by eastern cicada killer wasps (Sphecius speciosus)
Authors: Glon Mael G. , Thoma Roger F.
Published: May 2020

Burrowing crayfish are a polyphyletic group of crayfish adapted to life in habitats where surface water is only intermittently available. The burrowing activity of these crayfish creates refugia for numerous other species, making them allogenic ecosystem engineers. While excavating devil crayfish burrows in a roadside ditch in Southern Indiana, USA, a large cicada killer wasp carrying an even larger cicada landed near the authors. The wasp spent a few minutes manipulating its prey, then took flight and flew directly into an unoccupied crayfish burrow in the roadside ditch. The wasp emerged approximately ten minutes later without the cicada and flew away. Female cicada killer wasps typically excavate brooding burrows consisting of numerous cells in which they deposit cicadas for their young to feed on upon hatching. We believe that this particular cicada killer wasp was in the process of provisioning a brooding cell, but used a crayfish burrow instead of digging its own burrow, possibly to save energy. To our knowledge, use of a crayfish burrow by a cicada killer wasp has not been documented before and adds to the list of organisms that benefit from the ecosystem engineering of burrowing crayfish, highlighting the importance of giving these crayfish appropriate conservation attention.
Ontogenetic color change in the crayfish Cambarus b. bartonii and Faxonius obscurus: a test of Ortmann’s hypotheses
Authors: Hartzell Sean M.
Published: May 2020

In crayfish, intraspecific coloration can vary due to a variety of factors such as diet, genetic variation, environment, and ontogeny. Ortmann (1906) hypothesized that the crayfish Cambarus bartonii bartonii and Faxonius obscurus exhibit an ontogenetic shift in color change, with greener coloration in younger individuals of both species diminishing with age in larger specimens. However, this hypothesis has never been quantitatively tested. This work incorporated digital image analysis to quantify coloration of samples of C. b. bartonii and F. obscurus collected from two locations, respectively, in an eastern Pennsylvania stream. Examination for relationships between coloration (percent “green dominance”, i.e., the proportion of green in comparison to blue and red in photographs) and body size did not reveal any significant relationship between these variables in either crayfish species. Therefore, this study does not support the presence of ontogenetic color change in C. b. bartonii and F. obscurus, and suggests intraspecific variation of color in both species may be primarily influenced by other factors.
Memórias com a música em ambientes informais e religiosos: diálogos com processos formativos
Authors: Almeida Jéssica De
Published: May 2020

Este artigo tem o objetivo de discutir resultados parciais de uma pesquisa de doutorado que se referem às experiências com a música e o seu ensino em contextos informais e religiosos materializadas em narrativas musicais. Tal investigação adotou, como aporte teórico, as discussões sobre os conceitos formação (BRAGANÇA, 2011; CHIENÉ, 2010; CUNHA, 2010; DELORY-MOMBERGER, 2006; JOSSO, 2004; 2010a; 2010b; PASSEGGI, 2011b), história de vida e narrativa (ABRAHÃO, 2004; BOLÍVAR; DOMINGO; FERNÁNDEZ, 2001; DELORY-MOMBERGER, 2011; 2014; FERRAROTTI, 2010; 2014; JOSSO, 1999; 2016; PASSEGGI, 2011a; PINEAU; LEGRAND, 2012, e outros), principalmente, considerando que visou compreender as maneiras por meios das quais acadêmicos de um Curso de Licenciatura em Música produziriam sentidos para seus processos formativos a partir do desenvolvimento de biografias músico-educativas. Espera-se contribuir com o debate sobre as implicações de abordagens (auto)biográficas em processos formativos de professores, sobretudo, nas inter-relações entre esses e memórias com a música.
A representação do híbrido na pintura de bosch
Authors: Pol Yasmin
Published: May 2020

O presente trabalho tem como objetivo conceituar historicamente o híbrido, evidenciando as significações a ele atribuídas, e relacioná-lo com a obra de Hieronymus Bosch. Para a compreensão dessas relações, é preciso entender separadamente cada elemento, por isso, o artigo é dividido em três partes: o conceito de híbrido, a vida e obra de Hieronymus Bosch e análise de uma obra deste artista. Esta breve análise de imagem deixa evidente as visões e conotações atribuídas ao híbrido desde a Antiguidade. Como metodologia de pesquisa foram utilizados livros e artigos científicos que abordam o tema, além do levantamento e estudo de obras de Bosch.
Ateliê - Território da Artista: relacionando arte, território, ancestralidade negra e memórias
Authors: Leonel Priscila
Published: May 2020

Este artigo é um recorte da minha atual pesquisa de doutorado em Processos Artísticos, na linha da Cerâmica Latino-Americana, neste estudo realizei uma recuperação de conhecimentos e saberes ancestrais que perpassam a minha produção artística, principalmente em cerâmica. Concebendo uma produção de objetos relacionados à memória, trago também uma relação com ancestralidade negra, aproximando uma discussão sobre questões do afrodescendente, no contexto social do estado de São Paulo, lugar onde nasci e me formatei como artista. Dessas descobertas da artista no território abriram-se possibilidades de olhar para o tempo/espaço como parte do meu processo artístico e de identidade cultural.
