Neuromuscular performance and hormonal responses to military operational stress in men and women. J Strength Cond Res 35(5): 1296–1305, 2021—Women have recently been integrated into ground close combat positions; however, there are limited data in women in these roles. We aimed to test the hypothesis that there would be no sex-specific neuromuscular responses, but hormonal signaling would be differentially impacted when exposed to simulated military operational stress (SMOS). Neuromuscular performance was assessed daily using a tactical mobility test (TMT) in 54 male and 15 female military members. Blood was drawn before/after TMT. Mood states were assessed each morning. Unloaded 300-m shuttle time increased 6% in both sexes and remained 7% higher after 1 day of recovery compared with baseline (p < 0.05 for both), whereas performance was maintained in other TMT events (p > 0.05). Growth hormone increased in men, but not women, before to after TMT (p < 0.001 vs. p = 0.086). Women experienced a greater decline in insulin-like growth factor-I across days compared with men (

= 0.778 vs. 0.209, respectively, p < 0.001). Brain-derived neurotrophic factor increased significantly in men only from before to after TMT on day 1 (men: +107% vs. women: +10%) but no difference on days 3 or 4. Cortisol increased 69% from before to after TMT when averaged by sex and day. Negative mood states (depression, tension, and anger) and altered hormonal concentrations were associated with poorer TMT performance. Acute SMOS differentially impacted circulating hormonal milieu in men and women, but no differences in physical performance responses. Unloaded 300-m shuttle was negatively impacted while other fitness domains were maintained. Relationships between performance and mood/endocrine signaling highlight the potential for self-report measures and biomarkers to serve as indicators of performance change.

Rico-González, M, Pino-Ortega, J, Rojas-Valverde, D, and Arcos, AL. Comparing sampling frequencies to measure collective tactical variables during soccer training. J Strength Cond Res 36(10): 2862–2867, 2022—The sampling frequency of microsensors that measure the position of the players in team sports is a variable that could affect the accuracy of the measurement. The aim of this study was to assess the impact of the sampling frequency on the outcomes of tactical behavior variables during soccer training. Sixteen U16 male soccer players participated in the study. Three tactical variables (change in the geometrical center position [cGCp], mean distance between players [mean-DbP], and total area [TA]) were measured at 4 different sampling frequencies (i.e., 10, 4, 2, and 1 Hz) during a 7+goalkeeper-a-side soccer match by a time motion tracking system using inertial measurement units (IMU; WIMU PRO, RealTrack Systems, Almeria, Spain). Significant (p < 0.01) and substantial (ES = moderate-large) differences were found in the cGCp values across all sampling frequencies. Several significant (p < 0.05) and substantial (ES = small-moderate) differences were found in the mean-DbP values between 10 data per second and the rest of the sampling frequencies. There were no significant (p > 0.05) and substantial (ES = trivial) differences in the TA values across all sampling frequencies. The sampling frequency affects the outcomes of cGCp and mean-DbP but does not affect the values of TA. The outcomes of the studies that assess collective tactical behavior should be compared with caution if GC-related and distance variables were measured using different sampling frequencies. In addition, it seems that a smaller amount of data could be sufficient to measure area variables with greater magnitudes.

Santagnello, SB, Martins, FM, de Oliveira Junior, GN, de Sousa, JdeFR, Nomelini, RS, Murta, EFC, and Orsatti, FL. Resistance training–induced gains in muscle strength and power mediate the improvement in walking speed in middle-aged women who are breast cancer survivors. J Strength Cond Res XX(X): 000–000, 2021—(a) Ascertain whether lower muscle mass, strength (1 repetition maximum [1RM]), and power (Pmax) in middle-aged women who are breast cancer survivors (BCS), when compared with women of a similar age never diagnosed with cancer (WNC), are related with lower walking speed (WS). (b) Ascertain whether changes in WS are associated with changes in muscle mass, 1RM, and (or) Pmax after resistance training (RT) in middle-aged BCS. A cross-section study was performed. Twenty WNC and 21 BCS were evaluated for lean mass of legs (LLM), 1RM (knee extension), muscle quality index (MQI = 1RM/LLM), Pmax (maximum muscle power–knee extension), and fast WS (10 and 400-meters). Randomized clinical trial was performed. The BCS were randomly divided into the control group (n = 9) and the RT group (n = 11). Breast cancer survivors exhibited lower 1RM (24.2%, p ˂ 0.001), Pmax (30.6%, p ˂ 0.001), MQI (22.2%, p = 0.001), and WS (10-m = 17.0%, p ˂ 0.001 and 400-m = 10.5%, p = 0.002) than WNC. Resistance training increased 1RM (31.6%, p = 0.001), MP (29.0%, p = 0.012), MQI (28.5%, p = 0.008), and WS (10-m = 9.4%, p = 0.009 and 400-m = 6.2%, p = 0.006) in BCS. The changes in WS were positively associated with 1RM (10-m = 68%, p = 0.001 and 400-m = 37%, p = 0.036) and Pmax (10-m = 56%, p = 0.005 and 400-m = 40%, p = 0.027) and MQI (10-m = 63%, p = 0.043 and 400-m = 37%, p = 0.035). Resistance training–induced gains in muscle strength and power mediate the improvement in WS in middle-aged BCS. Resistance training is an effective strategy to improve WS in middle-aged BCS.

Objectives

To determine trends in clinical practice for individuals with DSD requiring gonadectomy.

Design

Retrospective cohort study.

Methods

Information regarding age at gonadectomy according to diagnosis; reported sex; time of presentation to specialist centre; and location of centre from cases reported to the International DSD Registry and who were over 16 years old in January 2019.

Results

Data regarding gonadectomy were available in 668 (88%) individuals from 44 centres. Of these, 248 (37%) (median age (range) 24 (17, 75) years) were male and 420 (63%) (median age (range) 26 (16, 86) years) were female. Gonadectomy was reported from 36 centres in 351/668 cases (53%). Females were more likely to undergo gonadectomy (n = 311, P < 0.0001). The indication for gonadectomy was reported in 268 (76%). The most common indication was mitigation of tumour risk in 172 (64%). Variations in the practice of gonadectomy were observed; of the 351 cases from 36 centres, 17 (5%) at 9 centres had undergone gonadectomy before their first presentation to the specialist centre. Median age at gonadectomy of cases from high-income countries and low-/middle-income countries (LMIC) was 13.0 years (0.1, 68) years and 16.5 years (1, 28), respectively (P < 0.0001) with the likelihood of long-term retention of gonads being higher in LMIC countries.

Conclusions

The likelihood of gonadectomy depends on the underlying diagnosis, sex of rearing and the geographical setting. Clinical benchmarks, which can be studied across all forms of DSD will allow a better understanding of the variation in the practice of gonadectomy.
On distance Laplacian spectrum of zero divisor graphs of the ring $\mathbb{Z}_{n}$
Authors: Pirzada S. , Rather B.A. , Chishti T.A.
Published: March 2021

For a finite commutative ring $\mathbb{Z}_{n}$ with identity $1\neq 0$, the zero divisor graph $\Gamma(\mathbb{Z}_{n})$ is a simple connected graph having vertex set as the set of non-zero zero divisors, where two vertices $x$ and $y$ are adjacent if and only if $xy=0$. We find the distance Laplacian spectrum of the zero divisor graphs $\Gamma(\mathbb{Z}_{n})$ for different values of $n$. Also, we obtain the distance Laplacian spectrum of $\Gamma(\mathbb{Z}_{n})$ for $n=p^z$, $z\geq 2$, in terms of the Laplacian spectrum. As a consequence, we determine those $n$ for which zero divisor graph $\Gamma(\mathbb{Z}_{n})$ is distance Laplacian integral.

The typology of ethical climate is pointed out; the main aspects related to ethical climate are discussed, such as ethical behaviour, organizational commitment, and job satisfaction. Different Lithuanian and foreign scholars’ research papers and research carried out on the subject of ethical climate have been analysed and systematized. In applying theoretical knowledge and practical methodology, the research has been carried out on ethical climate in the Siauliai County State Tax Inspectorate. The research revealed the existing types of ethical climate in the organization, the external influential factors, and their relationship with the ethical climate on the employees’ job satisfaction in the organization. After summarizing the results of the research the following conclusions have been drawn up: the type of ethical climate of public interests is dominated in the Siauliai County State Tax Inspectorate, the office employees are concerned about the society welfare and try not to violate its interests. It has been concluded that the employees of the organization are most satisfied with their relationship with executives. The conclusions of scholars have been confirmed that caring, law and rules, independence, efficiency, public interest ethical climate types, and staff’s job satisfaction correlate and are related among themselves.
Ethical and Socially Responsible Behaviour of Tax Advisers: The Case of Moral Beliefs
Authors: Prauliņš Artūrs , Bratka Valda
Published: March 2021

Financial crisis and corporate scandals have turned the spotlight on the role played by tax advisors in the creation and development of tax minimization schemes. This paper explores whether society is entitled to expect tax advisors to behave in an ethical and socially responsible manner and to have general moral obligations. A modern contradictory role of tax advisors has been analyzed, influencing a predatory entrepreneurial culture, and the conflicting mental attitude of society and clients have been investigated. The study concludes that significant differences in tax advisors’ ethical sensitivity and personal moral beliefs have been insurmountable obstacles to meeting these expectations thus far.
Mobile communication of the fifth generation and its place in the transformation processes of digitalization of the economy
Authors:   National Academy of Sciences of Ukraine, Kniaziev Sviatoslav
Published: March 2021

The formation of the digital economy in the world is due to the development of a number of new breakthrough technologies that are unfolding in the process of the Fourth Industrial Revolution. The basic of them is the fifth generation of mobile communication (5G), which provides the opportunity to implement a large number of new information and communication technologies, as well as hardware solutions and products for the economy and society. Countries that take the leadership in building 5G infrastructure and adopting fifth-generation mobile standards will be able to apply their successful expertise to deploy a new generation of communications in other countries, opening up ample opportunities to enhance technological, economic and geopolitical impact on them. The paper is devoted to the analysis of trends in the formation and development of mobile technologies of the fifth generation in the world and its impact on the processes of digitalization of the economy, as well as the identification of promising practices for their implementation in Ukraine. In the course of the analysis, it is defined that 5G, unlike the previous generations of communication, is peculiar to large-scale virtualization, which goes beyond exclusively hardware and infrastructural decisions, and the majority of its functionality is realized by a software way. That is why it is often called not a network, but a system or platform that enables the implementation of a significant number of services and solutions, in particular: high-speed data transmission, a wide range of Internet of Things services, storing large data sets in cloud storage, virtual reality services, smart automation and robotics of production, unmanned vehicles, etc. But 5G is also characterized by a number of shortcomings (due to the use of short radio waves with rapid attenuation) that actualize the challenges, associated with increasing consumption of raw materials and energy, increased anthropogenic burden, lack of study of this technology’s potential negative impact on human health and local ecosystems etc. It is defined, that 5G-technologies, being a new event, according to the concept of technology life cycle are in the lower part of the S-shaped technological curve. This stage of technology development is characterized by significant financial investments and small economic returns, associated primarily with sales of radio frequency resources. Measures are proposed to avoid in the future for Ukraine the role of a raw material appendage of technologically developed countries, in terms of creating a favorable national institutional environment and ensuring support and encouragement of the development of new digital communication technologies.

Published: March 2021

In modern conditions, intellectual capital is recognized as a priority type of enterprise capital. Its presence, quality and quantity serve as the key to the growth of their competitiveness and economic efficiency. Taking this into account, this article has systematized the existing methodological approaches to determining the size, dynamics and level of intellectual capital. An assessment of the value of intellectual capital is carried on the example of an enterprise with embodiment of methodological approaches recognized by the world scientific community. The result showed the existence of a tendency to a reduction of the intellectualization of assets, a low level of intellectual growth at the enterprise. The revealed state can be explained by the simultaneous effect of various factors: a low level of development and activity of the stock market in Ukraine, occasional transactions, when buying and selling shares, defines their underestimated (individual) assessment; revaluation of the value of tangible assets (primarily accounts receivable, inventories, financial assets), etc. A decomposition conceptual model for assessing intellectual capital in the context of digitalization has been developed, which will allow measuring the level of intellectual capital. The proposed model for assessing the intellectual capital of enterprises in the context of the digitalization of the economy is more effective than previously established in researches analyzed in this paper, since its implementation in practice is inherent with lower transaction costs. Also, another positive moment of this model is that the assessment process is faster and more reliable.
Formation Mechanism of the Velyka Vyska Syenite Massif (Korsun-Novomyrhorod Pluton, Ukrainian Shield) Derived from Melt Inclusions in Zircon

Published: March 2021

The formation of leucosyenites in the Velyka Vyska syenite massif was provoked by the liquation layering of magmatic melt. This assumption is based on the presence of two primary melt inclusions of different chemical composition in zircon crystals from Velyka Vyska leucosyenites. They correspond to two types of silicate melts. Type I is a leucosyenite type that contains high SiO2 concentrations (these inclusions dominate quantitatively); type II is a melanosyenite type that contains elevated Fe and smaller SiO2 concentrations. The liquation layering of magmatic melt was slow because the liquates are similar in density; leucosyenite melt, which is more abundant than melt of melanosyenite composition, displays greater dynamic viscosity; the initial sizes of embryos of melanosyenite composition are microscopic. Sulphide melt, similar in composition to pyrrhotite, was also involved in the formation of the massif. Zircon was crystallized at temperatures over 1300°С, as indicated by the homogenization temperatures of primary melt inclusions. The REE distribution spectra of the main parts (or zones,) of zircon crystals from the Velyka Vyska massif are identical to those of zircon from the Azov and Yastrubets syenite massifs with which high-grade Zr and REE (Azov and Yastrubets) ore deposits are associated. They are characteristic of magmatically generated zircon. Some of the grains analyzed contain rims that are contrasting against the matrix of a crystal, look dark-grey in the BSE image and display flattened REE distribution spectra. Such spectra are also typical of baddeleyite, which formed by the partial replacement of zircon crystals. The formation of a dark-grey rim in zircon and baddeleyite is attributed to the strong effect of high-pressure СО2-fluid on the rock. The formation patterns of the Velyka Vyska and Azov massifs exhibit some common features: (а) silicate melt liquation; (b) high ZrO2 concentrations in glasses from hardened primary melt inclusions; (c) the supply of high-pressure СО2-fluid flows into Velyka Vyska and Azov hard rocks. Similar conditions of formation suggest the occurrence of high-grade Zr and REE ores in the Velyka Vyska syenite massif.

Published: March 2021

This article considers the distribution, formation, and chemical composition of mineral waters of the Eastern region of Ukraine, and, in particular, Donetsk, Luhansk, and Kharkiv regions. The main types of mineral waters, most characteristic of the Eastern region of Ukraine, are determined. Their formation and distribution are considered. Manifestations of ferrous, bromine, boron and iodine waters have been studied in this region, which significantly expands hydromineral and balneological resources. The application of ferrous mineral waters to organisms exposed to radiation has been studied. Since one of the consequences of radiation damage is a violation of oxidative homeostasis, the effect of ferrous mineral waters on the course of free radical processes in the body was studied. The peculiarities of the organic composition and biological properties of Berezivsky mineral waters have been studied to identify them as Naftusya-type waters. It is established that Berezivsky mineral waters do not have a pronounced radiomodifier effect. They are inhibitors of the enzymatic activity of catalase — a key regulator of oxidative metabolism, which leads to a deterioration in the vital functions of the body after irradiation. According to the obtained data of mass spectra, active organic substances of different classes, which are part of mineral waters of the Naftusya type, differ from organic substances of Berezivsky mineral waters, both qualitatively and quantitatively. Therefore, Berezivsky mineral waters cannot be referred to as the class of mineral waters of the Naftusya type. Some studies were also conducted and an array of statistics was obtained, which showed that the mineral waters of the Podilsk region, Naftusya and Berezivsky waters have pesticide concentrations less than 0.01 ng/dm3, i.e. 10 000 times lower than their permissible concentrations according to international standards. This confirms the possibility of widespread use and export of Ukrainian mineral waters, which is of national importance. Prospects for the development and use of mineral waters in the Eastern region are shown.
Perceived Access to Handguns Among Colorado High School Students
Authors: Brooks-Russell Ashley , Ma Ming , Brummett Sarah , Kelly Erin , Betz Marian
Published: March 2021

OBJECTIVES:

Access to firearms among youth can increase the risk of suicide or other injury. In this study, we sought to estimate the population prevalence of adolescent perception of firearm access by demographic, geographic, and other individual health characteristics.

METHODS:

The 2019 Healthy Kids Colorado Survey was an anonymous survey administered to a representative sample of high school students in Colorado. The survey was used to assess health behaviors and risk and protective factors. Analysis was conducted with weights to the state population of public high school students.

RESULTS:

In total, 46 537 high school students responded (71% student response rate; 83% school response rate). One in 5 students said it was “sort of easy” (11.1%) or “very easy” (8.8%) to access a handgun, with higher prevalence among male and older-aged youth and differences in racial and/or ethnicity groups. There were geographic differences such that students in schools in more rural areas were more likely to report perceived easy access. Students who had felt sad or hopeless, attempted suicide, or been in a fight were more likely to say they had access to a handgun.

CONCLUSIONS:

A relatively high proportion of youth have easy access to a firearm, with differences across age, sex, race and/or ethnicity, and geography. This highlights the need for efforts to address ways to reduce firearm access for youth, including secure storage at home, for the prevention of youth firearm suicide and other firearm injuries.
Tourism Development and the Local Businesses in Amritsar
Authors: Sharma Rachana , Kichloo Allina
Published: March 2021

Introduction. Taking into consideration the possibilities of growth and returns the tourism sector provides to the state of Punjab, of recent the Government of Punjab and the Amritsar city administration have made huge effort in expanding this sector by tapping and promoting various sites and activities for tourist absorption. This study delivers reasons for tourism development in Amritsar and proposes possible information for stakeholders to ensure the suitable tourism planning and management, especially contributing towards the local community.

Materials and Methods. Prominent categories of business operators i.e., restaurant owners, traditional shopkeepers, employees from the hospitality sector which included hotels, guest houses, hostels and lastly travel agency owners were interviewed for this study. This sample of 120 respondents was drawn from the inner and outer city areas of Amritsar city of Punjab (India).

Results. Tourism is emerging as a ‘saviour economy’ for Amritsar, as a major part of Amritsar’s economy directly and indirectly is dependent on this sector. Business community in Amritsar largely perceives the impacts of tourism development positively. However, respondents felt that the business in Amritsar is also getting negatively affected due to mono–centric development, overflow of tourists and expansionist tourism-centric policies. Tourism development policy can perform better by taking local economies into consideration and increasing participation of local communities in tourism development. This way tourism can create an undeniably positive impact on local communities and local businesses.

Discussion and Conclusion. As the current development model of the city is tourism centric, there is an insufficiency in growth of allied sectors as well as in development programmes and a miscoordination is there between different significant stakeholders. This study will be useful to various stakeholders like development authorities, planners, and scholars etc who are interested in addressing the developmental issues being faced by tourist cities. The usefulness of this study lies in the fact that it demonstrates how tourism can be used as a tool for regional development by gaining resident support.

Authors: Georgieva A. , Stoyanov J. , Tsandev N. , Sivrev D.
Published: March 2021

Background: Norsodyne is a new material for conservation and durable preservation of biological objects. The form we use is H 13212 TAE (Polynt Composites USA, Inc., Bergamo, Italy). This is an unsaturated polyester resin in styrene that is of low styrene emission. Features: resin has a specific weight 1.10 g/cm2 at 20°C. Using test method MT-CUT23V the manufacturer has established that Brookfield viscosity at 23°C is 450-650 mPa.s. The jelly starts in 14-18 minutes and reaches its peak in 27-37 minutes at 23°C too. Acording to the test results of ISO 527 (2012) tensile strength of Norsodyne is 57 MPa and flexural strength is 98 MPa (ISO 178 (2011). Conclusion: This characteristic of Norsodyne indicates that the material can be used for the preservation and long-term storage of anatomical preparations for the needs of anatomy training. However, the Norsodyne needs special storage conditions. The material should be stored in a dark place. According to the manufacturer shelf life at 23°C in the dark is six months then spontaneous rubbing begins. The manufacturer's recommendations are: Store in the shade, out of direct sunlight. Keep storage temperature below 25°C. Unseal container just before use. Shelflife will be reduced reaching higher temperature.
Bank ownership and drivers of credit growth in Central, Eastern and South-Eastern Europe
Authors: Iwanicz-Drozdowska Małgorzata , Witkowski Bartosz
Published: March 2021

In this paper, we analyse the determinants of credit growth for banks operating in 20 countries in the post-communist Central, Eastern and South-Eastern Europe (CESEE). We focus on foreign-owned banks and the parent-subsidiary nexus against the background of all banks operating in this part of Europe. Our goal is to determine whether the macroeconomic and bank-specific determinants for host countries have a similar impact on the entire group of banks operating in CESEE and on its subset of foreign-owned banks and whether the rate of credit growth could be considered ceteris paribus equal across the foreign-owned and the complete set of banks in the CESEE. To this end, we use panel data regressions on approximately 4,600 bank-year observations over the period from 1995 to 2014. We conclude that the determinants of banks’ behaviour in the CESEE countries are consistent regardless of these banks’ ownership, the period and their EU membership. Although having a foreign investor expands the set of relevant determinants, the presence of such investors does not overshadow the importance of local conditions.
The state of the state – Economic property rights and firm profitability versus corruption. New evidence from the Czech Republic
Authors: Malinowska A.P.
Published: March 2021

Despite significant advances in economic literature on the relationship between graft and economic growth, the consensus in nowhere in sight. The current paper enriches the extant literature on the subject by: 1) extending econometric techniques in an attempt to quantify and model institutional development; and 2) providing novel results on the dynamics between non-standardised and standardised institutional metrics. Utilising a new dataset compiled for 423 publicly quoted Czech, non-financial companies with macroeconomic and institutional metrics, we fashion a dynamic model approximating the interactions between the country's institutional development and firm profits as well as examining the relationship between the Czech corruption and the national institutional framework in the years of 2007–2016. The economic property rights appear to contribute to firm accounting profits- and cash flow-based profitability metrics. As regards the anti-corruption policies, the study's outcomes indicate that improvement in economic property rights could have propelled the positive impact of lax anti-corruption government action and inefficient judiciary on firm profits.

The objective: to study the effectiveness of hemostatic therapy with tranexamic acid in pregnant women with miscarriage that started. Materials and methods: The study group included 110 pregnant women with a miscarriage that began with the onset of retrochoric hematoma, from 5 to 22 weeks of gestation. The main group was 60 pregnant women who received hemostatic therapy with the drug tranexamic acid Vidanol in a daily dose of 1000–1500 mg until stopping the bleeding. The comparison group consisted of 50 pregnant women who received standard hemostatic therapy with etamsylatum. On ultrasound, retrochorionic / retroplacental hematomas were noted in 27 women of the main group (45%) and 22 patients in the comparison group (44%), extramembrane hematomas were diagnosed in 8 (13.3%) and 9 (18%) women, respectively. Placenta presentation was observed in 7 (11.7%) and 8 (16%) women of both groups, respectively. In the rest of pregnant women there was a bloody discharge from the genital tract as a result of detachment of the chorion / placenta or membranes without formation of hematoma. The obtained data are processed by the statistical method using the Microsoft Excel computer program. Results. Stopping bleeding with the use of tranexamic acid averaged over 2 days from the start of therapy, the duration of bleeding was 2.1±0.2 days, whereas in the comparison group, the duration of bleeding was significantly higher than 5.7±0.3 (p<0,01). The need for inpatient treatment was in the main group of 9.7±0.8 bed-days and 15.6±2.7 bed-days, respectively (p<0.05). When using the drug tranexamic acid, the organization and resorption of hematomas in the uterus occurred in a shorter time – 19 of 35 (54.3%) women in the primary group and 10 in 31 (32.3%) women in the comparison group. The total absence of hematoma is noted in the main group for 1.2±0.4 weeks, in the comparison group for 4.8±0.5 weeks (p<0.05). Conclusion.

The objective: to study influence of various options of expeditious treatment of apoplexy of ovaries on a condition of ovariale reserve. Materials and methods. Clinical-laboratory and tool examination of 65 patients with an apoplexy of an ovary whom the first time operated with laparoscopic access was conducted. These patients were included in prospective research and divided into two groups depending on the hemostasis used during operation. 1 group included 35 patients, hemostasis with which carried out by means of bipolar coagulation, into the 2nd group – 30 patients, bleeding from ovary was stopped by means of suture. Results. Results of the conducted researches testify, that hemostasis exercise at operations at patients with it was carried out by an apoplexy of the ovary, whatever way (bipolar current or suture), leads to loss of part of an ovariale reserve. To larger losses of ovariale reserve leads use for a stopping of bleeding of bipolar electrosurgery. Conclution. The received results need to be considered as at expeditious treatment of women with an ovary apoplexy, and at restoration of genesial function. Key words: ovary apoplexy, hemostasis, ovariale reserve.

The article presents an analysis of literature data and the results of own prospective studies of the application of the local iatrogenic injury method with the parallel introduction of plasma enriched with platelets into the basal layer of the endometrium in pregravid preparation for treatment with assisted reproductive technologies (ART) in patients with tubal peritoneal infertility and marked lag development of the endometrium. The objective: was to determine the optimal time for the injection of scratch scratching in pregravid preparation before the next cycle of ART treatment in patients with tubal peritoneal infertility and marked lag in the development of the endometrium. Materials and methods. The study included 109 patients with unsuccessful attempts to treat ART with a tubal peritoneal factor of infertility with a marked degree of lag in the development of the endometrium according to absolute indications. The subjects were divided into three groups. Group A – 47 patients who experienced a marked lag in the development of the endometrium during the control stimulation of superovulation during ART (ETC + ET) and suggested the application of the procedure of injection scaling of the endometrium on the 7th day of the stimulation cycle (CA). Group B – 32 patients who underwent the procedure of injection endometrial scratching on the 22nd day of the menstrual cycle (MC), which preceded the repeated cycle of CGI + ET. Group B – 30 patients who underwent the procedure of injection endometrial scratching on the 8th day of the MC, which preceded the repeated cycle of CCN + ET. Results. The use of injection scratches is more effective in improving the clinical outcomes of ART by using the methods of ART (CAS + ET) in the case of a pronounced delay in the development of the endometrium in the follicular phase of the CA on the 6th to 7th day of gonadotropin use. During treatment with ART, the frequency of pregnancy for each transfer of embryos (CHNBPE) was significantly lower, amounting to 9.4% (3 of 32) in group B and 7.1% (2 of 28) in group B than CHNBPE in group A – 27.7% (13 of 47). The frequency of early reproductive losses in group A was 23.1% (3 of 13), in group B – 66.7% (2 of 3), in group B – 50% (1 of 2). Conclusion. During the study of the optimal period for the appointment of injection scratching, it was found that injection endometrial scratching using autoplasma enriched with platelets demonstrates the best pregnancy rate for each transfer of embryos and low early reproductive loss if performed in the follicular phase of the stimulation cycle by 6–7th day of gonadotropins). Key words: infertility, methods of assisted reproductive technology, hypoplasia of the endometrium, hysteroscopy, plasma-riched platelets.

Raucous feminisms in neoliberal times: disruptive potential and the language of unruliness on Broad City
Authors: Eberhardt Maeve
Published: March 2021

There is no shortage of media representations that reinforce the neoliberal order, emphasise individual freedom and self-regulation and downplay structural inequities and systemic oppression. The current paper analyses an alternative representation that works to dismantle the dominant social order. I interrogate the disruptive potential of the ‘unruly woman’ on Broad City by exploring two discursive themes that present robust alternatives to a neoliberal feminist agenda: transgressive representations of female sexuality and desire and the visibility and normalisation of ‘unfeminine’ behaviours. Multimodal critical discourse analysis reveals how these themes highlight the tension between women’s will to act freely and the structural binds that keep groups oppressed beyond any freedom individuals may enjoy. As white women, Ilana and Abbi’s racial privilege is central in scaffolding their gendered freedom; however, self-reflexive critiques and inclusion of diverse, non-tokenised representations show a path forward towards a collective and liberatory intersectional feminism.

Published: March 2021

Atualmente, a internet permeia a vida de seres humanos em geral.  Os smartphones conectados à grande rede são parte fundamental dessa realidade hiperconectada. Uma de suas aplicações mais populares é a rede social WhatsApp, por meio da qual aproximadamente um bilhão de pessoas se conectam diretamente e em grupos. A interação em grupos de WhatsApp é um fenômeno contemporâneo. Eles são utilizados diariamente para a discussão de interesses pessoais, políticos, familiares, para elaboração de trabalhos escolares ou universitários e para debates sobre especificidades de uma profissão com vistas a melhorar as práticas dos membros de um grupo reunidos em torno de um interesse comum, por exemplo.  Este artigo, um ensaio teórico, discute a tessitura do conhecimento mediada por grupos com interesses comuns no WhatsApp. No desenvolvimento, foi caracterizado o cenário digital que levou ao surgimento e à difusão do WhatsApp, discutiu-se a construção do conhecimento na cibercultura e foram tecidas considerações sobre a tessitura do conhecimento em grupos dessa rede social.  Como resultado  deste trabalho, compreendeu-se que grupos no WhatsApp podem trazer a perspectiva de uma construção de conhecimento comunitária, caótica e onipresente dentro de um tema de interesse de um coletivo.

O presente trabalho tem como objetivo apresentar um olhar de docentes da educação básica, acerca das abordagens, dos métodos, das dificuldades e dos desafios para o ensino de Biologia Molecular em cursos de Educação a Distância (EaD). A pesquisa foi realizada por meio de análise qualitativa das concepções, com reflexões dos discursos produzidos em fóruns temáticos, durante os momentos de interação e colaboração de 36 cursistas/docentes, em um curso on-line de formação continuada de professores, oferecido pela Fundação CECIERJ. Constatou-se que durante os momentos de interação e colaboração promoveram-se discussões e reflexões significativas entre os docentes participantes do fórum, as quais refletiram em mudanças nas abordagens para o ensino de Biologia, assim como mudanças de atitude e mudanças conceituais. As reflexões dos docentes, promovidas ao longo dos fóruns, revelam um direcionamento positivo quanto ao uso da História da Ciência como alternativa ao ensino de Biologia, assim como o seu uso combinado às Tecnologias da Informação e Comunicação (TICs). Essa análise permitiu, também, a construção de um perfil de trabalho docente em que foi possível identificar quatro perfis de trabalho, no que diz respeito ao uso de recursos tecnológicos (digitais ou analógicos) e às abordagens comunicativas (dialógica ou expositiva), utilizados em sala de aula
