Authors: . Deryagina Larissa E. , Bulatetskiy Sergey V.
Published: October 2021

Неоднозначность процесса профессиональной адаптации вызывает постоянный интерес исследователей. Целью нашей работы было выявление особенностей физиологической и социально-психологической адаптации курсантов к условиям служебной деятельности.

Материалы и методы. В исследовании принимали участие курсанты факультета психологии Московского университета МВД РФ им.В.Я. Кикотя в количестве 30 человек (7 юношей и 23 девушки) в возрасте от 18 до 22 лет. Уровень социально-психологической адаптации определяли по методике диагностики Роджерса-Даймонд, вегетативную регуляцию ритма сердца оценивали по параметрам вариабельности ритма сердца (ВРС) по методике Р.М. Баевского согласно Евро-Американским рекомендациям. Исследование ВРС проводили дважды, до заступления в суточный наряд и после его окончания.

Результаты. Все испытуемые разделились на 3 группы по уровню адаптированности от низкого до высокого (НУ, СУ, ВУ). Умеренное преобладание симпатических влияний перед заступлением в наряд сменялось нарастанием вклада парасимпатической системы в регуляцию ритма сердца после наряда в группах НУ и СУ. В группе ВУ до наряда преобладала активация парасимпатического отдела нервной системы. После наряда наблюдался эутонический тип регуляции.

Выводы. 1. Уровень социально-психологической адаптации курсантов взаимосвязан с паттерном вегетативной регуляции ритма сердца в ситуации суточного наряда. 2. У лиц с высоким уровнем адаптивности сформирована относительно автономная система регуляции ритма сердца, которая в силу независимости ее элементов отличается большей пластичностью, что облегчает ее приспособление к изменяющимся условиям среды, включая, приспособление к условиям служебной деятельности.
МОНИТОРИНГ ВЛИЯНИЯ АНТРОПОГЕННЫХ ФАКТОРОВ НА ЛЕСНЫЕ БИОГЕОЦЕНОЗЫ ЮЖНОГО ПОБЕРЕЖЬЯ ОЗ. БАЙКАЛ
Authors: Mikhailova Tatiana A. , Shergina Olga V. , Kalugina Olga V.
Published: October 2021

Цель. Исследовать современное состояние лесных биогеоценозов в рекреационных зонах южного побережья Байкала по комплексу параметров древостоев и почвенного покрова, выявить участки, где необходимы безотлагательные меры по снижению рекреационной нагрузки.

Материалы и методы. В рекреационных зонах, характеризующихся высокими туристическими потоками, были заложены пробные площади (ПП) для обследования состояния лесных биогеоценозов по отечественным и международным методикам. Определяли изменение морфоструктурных параметров деревьев сосны обыкновенной (вида-индикатора), в образцах хвои – содержание биогенных элементов, белкового азота, фотосинтетических пигментов, некоторых поллютантов. Для исследования состояния почвы на ПП закладывали разрезы до глубины подстилающей породы. Определяли морфологические и физико-химические параметры верхних почвенных горизонтов, уровень обменных катионов в почвенном поглощающем комплексе (ППК), содержание подвижных форм ряда тяжелых металлов.

Результаты. При исследовании основных компонентов лесных биогеоценозов показано, что пресс рекреации является основным фактором, инициирующим процесс деградации почвы и древостоев. Системный характер этого процесса обусловлен биогеохимическими изменениями, вызванными нарушением физико-химических характеристик почвы, что приводит к дисбалансу биогенных элементов в ППК и ухудшению питательного режима почвы, соответственно, проявляется дисбаланс элементов в ассимиляционных органах деревьев и, как следствие, угнетение их ростовых параметров.

Применение результатов. Полученные данные служат информационной базой для региональных природоохранных органов при разработке мер, направленных на оптимизацию рекреационной нагрузки.

Заключение. Необходим постоянный мониторинг состояния лесов, окружающих Байкал и имеющих большую значимость в формировании стока воды в озеро.

Published: October 2021

The Coronavirus disease (COVID-19) pandemic has increased anxiety and stress among teacher education managers and has given rise to the question of whether they have the competencies to execute their operational responsibilities productively. The theories of resilience and transformational leadership underpin this study in which teacher education managers’ resilience and their responsiveness to the well-being of staff executing their operational practices in an open distance e-learning context were explored. A qualitative approach was adopted and virtual video conferencing interviews with teacher education managers were used to explore how they mitigated their strategic and operational roles and their managerial functions to ensure the well-being and organisational performance of staff working from home. Results revealed the experiences of distance managers to have been positive in that they implemented organisational strategies to mitigate the challenges faced to ensure wellness and performance among staff working from a distance. Further research applying a mixed-method design should be undertaken to determine how resilient managers and staff working from home are. That may yield different results.
The importance of language and culture to the growing Sino-Caribbean commercial relationship
Authors: Zamor Helene , Nicholls Alicia D. , Lee Albert Christopher
Published: October 2021

Language and culture play a critical role in international commercial relations. Since the 19th century, the English language has undeniably held the prominent position as the global lingua franca to facilitate communication between nations. However, China’s contemporary re-emergence as an economic superpower has expanded its global influence. Consequently, awareness of Chinese culture and language is becoming important not only globally, but also in the Caribbean, where China’s economic footprint has expanded considerably in recent years. This article conceptually explores the important role of language and culture within the growing Sino-Caribbean commercial relationship. Specifically, it discusses the potential impact of language on the trade and tourism sectors, which are two key industries that drive the economies of English-speaking Caribbean small island developing states. It does this by charting the development of the English and Chinese languages as dominant languages. It then briefly looks at the current level of Chinese engagement with the region in trade and, more contemporarily, the potential of greater Chinese tourism in the Caribbean. It discusses the value of deeper cultural and linguistic understanding in nurturing and expanding these relationships. Finally, the article concludes by providing meaningful recommendations on ways to mitigate cultural and linguistic barriers in order to promote deeper Sino-Caribbean trade and tourism.
Tuning single-walled aligned carbon nanotubes for optimal terahertz pulse generation through optical rectification of ultrashort laser pulses
Authors: Hassani Mohammad , Jahangiri Fazel
Published: October 2021

Terahertz radiation by optical rectification in single-walled highly aligned chiral carbon nanotubes (SWCNTs) irradiated by ultrashort laser pulses is comprehensively studied. We take into account the structural properties of SWCNTs, including the filling factor, alignment, and chirality, as well as the laser pulse parameters including the pulse duration and the wavelength. The second-order nonlinear susceptibility tensor and, consequently, polarization responsible for optical rectification in SWCNTs are derived based on symmetrical features.The effective dielectric constants of SWCNTs are also extracted using the effective medium approximation. Then, the propagation effects in terms of the group velocity dispersion and absorption at both pump and terahertz pulse frequency regions are investigated. By adjusting the laser and the structure effective parameters among those practically feasible, minimum velocity mismatch required for optimum optical rectification and coherent amplification at terahertz frequencies in SWCNTs are introduced. Comparing the electric field waveform and the spectrum of the generated terahertz pulses under various conditions reveals that SWCNTs with higher alignment and lower filling factor at chirality (6,4) irradiated by an ultrashort laser pulse with the wavelength of 1550 nm could provide the conditions for maximum terahertz radiation generation.
The negative consequences of sports betting opportunities on human capital formation: Evidence from Spain
Authors: Espadafor Mar , Martínez Sergi
Published: October 2021

The proliferation of on-site betting shops has received enormous public attention, becoming one of the most alarming health policy issues in contemporary cities. However, there is little evidence on whether its growing presence nearby vulnerable populations produce social harm beyond its known adverse individual effects. This study provides new evidence on the negative societal effects of betting houses. Our research design takes advantage of a new wave of openings in Madrid (Spain), which created a sudden increase in the supply of on-site gambling. Using a differences-in-differences design, we find that new betting houses decline nearby high schools’ educational performance, especially in public schools in less advantaged areas. This effect is neither trivial nor diminishing with time. This evidence suggests that betting houses increase inequality of educational opportunities. The ubiquity of betting houses around vulnerable populations in multiple regions drives us to think that these findings have relevant policy implications for many countries currently designing policies tackling the increase of problem gambling.

Authors: Chellappan Nonam , Raj Smitha G.
Published: October 2021

BACKGROUND Breast cancer is a systemic disease that requires treatment with surgery, chemotherapy, radiation, endocrine therapy and biological therapy. Neoadjuvant chemotherapy is the recent treatment of locally advanced breast cancer. The purpose of this study was to assess the acute toxicity of paclitaxel-based dose-dense and conventional neoadjuvant chemotherapy in locally advanced female breast cancer patients. METHODS In this study, neoadjuvant paclitaxel was given to a hundred locally advanced breast malignancies of female patients. Three weekly paclitaxel 200 mg/m2 ( 4 courses) was given for fifty patients and weekly paclitaxel 80 mg/m2 (10 courses) was given for fifty patients along with four-course of three weekly doxorubicin 50 mg/m2 given in both arms. Chemotherapy-induced acute toxicities in both arms were assessed weekly. RESULTS There was a significant increase in the incidence of anaemia in weekly chemotherapy patients at 7th week (28 % verse 10 %, P - value 0.022) and neutropenic infection at 11th week (28 % verse 10 %, P - value 0.022). There was a non-statistically significant increase in the incidence of leukopenia, thrombocytopenia and paraesthesia and myalgia in the weekly arm. There was a significant increase in the incidence of gastrointestinal toxicity like grade 3 stomatitis (at 4th - week), nausea and vomiting (at 4th, 7th, and 11th week ) in three weekly chemotherapy patients. CONCLUSIONS In this study, acute neurological and haematological toxicities were more in the weekly neoadjuvant chemotherapy arm and acute gastrointestinal toxicities were more in the three weekly neoadjuvant chemotherapy arm.

Published: October 2021

BACKGROUND Neuro-ophthalmology deals with complex systemic diseases that affect the visual system and pose a challenge for ophthalmologists. Here the focus is on the diseases of the nervous system that affect vision, ocular motility, or pupillary reflexes. Diplopia, a common symptom of cranial nerve palsy, may result from ophthalmic, orbital, or neurologic disorders. Our study intended to determine the aetiology of ocular motor nerve palsies. METHODS A cross-sectional study was conducted for two years at a tertiary care centre in South India. We evaluated 30 patients who came to the Ophthalmology OPD or were admitted, after obtaining the approval of the Ethics committee. RESULTS A total number of 30 patients who fulfilled the inclusion criteria were studied. There were 14 male and 16 female patients. The age range was 12 - 87 years with a mean age of 45 years. The highest incidence noticed was isolated sixth nerve palsy in 13 (43.3 %) patients. 11 patients had isolated third nerve palsy (36.7 %), while mixed ocular motor nerve palsies (third, fourth and sixth) were seen in 6 patients (20 %). None of them had isolated fourth nerve palsy. CONCLUSIONS  The sixth nerve continued to be the most common among the ocular motor nerve palsies. Meningitis was the major cause.  Diabetes and trauma, infections with CNS inflammation accounted for a majority of third nerve palsies.  Multiple cranial nerve palsies had varied aetiology like HIV Infection, Tolosa Hunt Syndrome, aneurysm of intracavernous part of ICA, cavernous sinus thrombosis and trauma.  The patient’s age, associated symptoms, clinical features and types of palsy are of great importance to choose appropriate radiological methods to study and treat these isolated cranial nerve palsies.

Idiopathic Pulmonary Arteriovenous Malformation - A Rare Entity
Authors: Hepat Sanyukta , Kabra Ruchita , Wadekar Abhijit , Acharya Sourya , Shukla Samarth , Kumar Sunil
Published: October 2021

Pulmonary arteriovenous malformation (PAVM) is one of the rare pulmonary vascular anomalies. Pulmonary arteriovenous malformation results in right to left shunt due to the abnormal communications between the pulmonary arteries and the pulmonary veins bypassing the normal capillary bed.1 This condition being rare could be easily missed, hence, it is essential for clinicians to suspect it based on the classical clinical features. This helps in early diagnosis and deciding further appropriate treatment option. Here we report the case of a patient affected by a large idiopathic pulmonary arteriovenous malformation in the right lung. Most patients with pulmonary arteriovenous malformation are asymptomatic. This is due to the chronic compensation and secondary erythrocytic response. Dyspnoea due to PAVMs are a result of right-to-left shunt. Initial diagnostic tools include chest radiography and contrast enhanced computed tomography but the gold standard is pulmonary angiography.2 Because AVM has substantial morbidity rates associated with it, all patients with PAVMs who can undergo embolization should be treated with transcatheter embolization. In rest of the patients, surgical excision should be considered. The main objective of this study was to highlight the early suspicion and diagnosis of pulmonary arteriovenous malformation as this is easily missed and leads to undue delay of treatment.
Full Mouth Rehabilitation – The Enigma Continues
Authors: Bhoyar Anjali Giridhar , Sathe Seema Prakash
Published: October 2021

‘ No thi ng Ch an ge s i f No t hi ng Ch an ge s’ Treating a case of full mouth rehabilitation has remained a challenge till date. Dentistry has witnessed many advancements in terms of material science, technology and treatment procedures. What has not evolved is the thought process of application of these newer methods and technology. Any treatment procedure performed on a patient is not a straightforward mathematical calculation which can be implemented in a specified manner. Clinical processes, especially a case of full mouth rehabilitation requires comprehensive knowledge and understanding of the stomatognathic system. The word rehabilitation in itself conveys responsibility. A lot is involved at both the ends - the receiver (patient) and the donor (the rehabilitation specialist). The oxford dictionary defines rehabilitation as ‘The action of restoring someone to health or normal life through training and therapy after imprisonment, addiction, or illness.’ 1 It is a great responsibility on restoring dentist to bring the abnormal and compromised oral functions back on track. The multidisciplinary dimension of the treatment cannot be ignored. Although the culmination of an elaborate treatment is by a restoring specialist which happens to be prosthodontist most of the time, other specialists such as endodontist, periodontist, oral surgeon, orthodontist and an oral radiologist play a significant role throughout the planning and execution. It is advisable to seek expert opinion and include specialty procedures whenever deemed necessary.

End-to-end AutoML has attracted intensive interests from both academia and industry, which automatically searches for ML pipelines in a space induced by feature engineering, algorithm/model selection, and hyper-parameter tuning. Existing AutoML systems, however, suffer from scalability issues when applying to application domains with large, high-dimensional search spaces. We present VOLCANOML, a scalable and extensible framework that facilitates systematic exploration of large AutoML search spaces. VOLCANOML introduces and implements basic building blocks that decompose a large search space into smaller ones, and allows users to utilize these building blocks to compose an
execution plan
for the AutoML problem at hand. VOLCANOML further supports a Volcano-style
execution model
- akin to the one supported by modern database systems - to execute the plan constructed. Our evaluation demonstrates that, not only does VOLCANOML raise the level of expressiveness for search space decomposition in AutoML, it also leads to actual findings of decomposition strategies that are significantly more efficient than the ones employed by state-of-the-art AutoML systems such as auto-sklearn.
CGM

Published: October 2021

Local differential privacy (LDP) is a well-established privacy protection scheme for collecting sensitive data, which has been integrated into major platforms such as iOS, Chrome, and Windows. The main idea is that each individual randomly perturbs her data on her local device, and only uploads the noisy version to an untrusted data aggregator. This paper focuses on the collection of streaming data consisting of regular updates,
e.g.
, daily app usage. Such streams, when aggregated over a large population, often exhibit strong
autocorrelations
,
e.g.
, the average usage of an app usually does not change dramatically from one day to the next. To our knowledge, this property has been largely neglected in existing LDP mechanisms. Consequently, data collected with current LDP methods often exhibit unrealistically violent fluctuations due to the added noise, drowning the overall trend, as shown in our experiments.

This paper proposes a novel
correlated Gaussian mechanism
(
CGM
) for enforcing (ϵ, δ)-LDP on streaming data collection, which reduces noise by exploiting public-known autocorrelation patterns of the aggregated data. This is done through non-trivial modifications to the core of the underlying Gaussian Mechanism; in particular, CGM injects temporally correlated noise, computed through an optimization program that takes into account the given autocorrelation pattern, data value range, and utility metric. CGM comes with formal proof of correctness, and consumes negligible computational resources. Extensive experiments using real datasets from different application domains demonstrate that CGM achieves consistent and significant utility gains compared to the baseline method of repeatedly running the underlying one-shot LDP mechanism.
Errata for "teseo and the analysis of structural dynamic graphs"
Authors: De Leo Dean , Fuchs Per , Boncz Peter
Published: October 2021

In our paper [4], we experimentally evaluated our work, Teseo, together with five other systems under the LDBC Graphalytics benchmark [6]. We developed and publicly released [2] an ad-hoc driver for the purpose. Since the time the paper was published, a bug [1] in the driver has been found. Due to this bug, we discovered that the completion times for Graphalytics have been incorrectly measured by 1 second or slightly more than their actual values. This issue involves the results of Table 2, Figure 8 and Table 3 reported in our paper [4]. Still, because the bug equally affected all systems evaluated and it is only related to the measurements, most of the comparisons and the general conclusions in the paper still hold.
Robust voice querying with MUVE
Authors: Wei Ziyun , Trummer Immanuel , Anderson Connor
Published: October 2021

Recently proposed voice query interfaces translate voice input into SQL queries. Unreliable speech recognition on top of the intrinsic challenges of text-to-SQL translation makes it hard to reliably interpret user input. We present MUVE (Multiplots for Voice quEries), a system for robust voice querying. MUVE reduces the impact of ambiguous voice queries by filling the screen with multiplots, capturing results of phonetically similar queries. It maps voice input to a probability distribution over query candidates, executes a selected subset of queries, and visualizes their results in a multiplot.

Our goal is to maximize probability to show the correct query result. Also, we want to optimize the visualization (e.g., by coloring a subset of likely results) in order to minimize expected time until users find the correct result. Via a user study, we validate a simple cost model estimating the latter overhead. The resulting optimization problem is NP-hard. We propose an exhaustive algorithm, based on integer programming, as well as a greedy heuristic. As shown in a corresponding user study, MUVE enables users to identify accurate results faster, compared to prior work.
COMPARE
Authors: Siddiqui Tarique , Chaudhuri Surajit , Narasayya Vivek
Published: October 2021

Data analysis often involves
comparing
subsets of data across many dimensions for finding unusual trends and patterns. While the comparison between subsets of data can be expressed using SQL, they tend to be complex to write, and suffer from poor performance over large and high-dimensional datasets. In this paper, we propose a new logical operator COMPARE for relational databases that concisely captures the enumeration and comparison between subsets of data and greatly simplifies the expressing of a large class of comparative queries. We extend the database engine with optimization techniques that exploit the semantics of COMPARE to significantly improve the performance of such queries. We have implemented these extensions inside Microsoft SQL Server, a commercial DBMS engine. Our extensive evaluation on synthetic and real-world datasets shows that COMPARE results in a significant speedup over existing approaches, including physical plans generated by today's database systems, user-defined functions (UDFs), as well as middleware solutions that compare subsets outside the databases.
Beyond equi-joins

Published: October 2021

We study theta-joins in general and join predicates with conjunctions and disjunctions of inequalities in particular, focusing on
ranked enumeration
where the answers are returned incrementally in an order dictated by a given ranking function. Our approach achieves strong time and space complexity properties: with
n
denoting the number of tuples in the database, we guarantee for acyclic full join queries with inequality conditions that for
every
value of
k
, the
k
top-ranked answers are returned in
O
(
n

) time. This is within a polylogarithmic factor of
O
(
n
+
k
log
k
), i.e., the best known complexity for equi-joins, and even of
O
(
n
+
k
), i.e., the time it takes to look at the input and return
k
answers in any order. Our guarantees extend to join queries with selections and many types of projections (namely those called "free-connex" queries and those that use bag semantics). Remarkably, they hold even when the number of join results is

n
ℓ

for a join of
ℓ
relations. The key ingredient is a novel
O
(
n
polylog
n
)-size
factorized representation of the query output
, which is constructed on-the-fly for a given query and database. In addition to providing the first nontrivial theoretical guarantees beyond equi-joins, we show in an experimental study that our ranked-enumeration approach is also memory-efficient and fast in practice, beating the running time of state-of-the-art database systems by orders of magnitude.
Solons Fr. 12 G.-P.2(= 9 W.2): ein Textvorschlag
Authors: Solitario Michele
Published: October 2021

This paper proposes a new conjecture for Solon fr. 12 G.-P.2(= 9 W.2). In this, as in other poems, Solon shows a clear desire to present himself as an expert in the political milieu and to serve as a guide for the community of Athens. The politician’s penetrating gaze, his far-sighted νόος, is able to graspin nucethe development of political dynamics which, if they prevail, could mean the ruin of the city as a whole. Solon frames his νόος as an indispensable tool for the analysis of the city and its optimal and timely planning. To a secular conception of the νόος, which is the essential characteristic of the excellent politician, is added a traditional one that considers the νόος as a gift of Apollo. In this way, Solon appears as a politically engaged poet of the πόλις who mediates between the fighting factions and tries to work for the good of the community.
Kształtowanie profilu smakowo-zapachowego mięsa wołowego w procesie dojrzewania na sucho
Authors: Domaradzki Piotr , Florek Mariusz , Litwińczuk Zygmunt
Published: October 2021

Dojrzewanie to naturalny proces enzymatyczny zachodzący w tkance mięśniowej post mortem. Aktualnie praktykowane są dwie techniki dojrzewania mięsa: na mokro (w warunkach próżniowych) i na sucho (tradycyjne, bez pakowania, w powietrzu o określonej temperaturze i wilgotności). Dojrzewanie wołowiny na mokro jest i pozostanie dominującą metodą stosowaną w przemyśle mięsnym ze względu na możliwość zwiększania kruchości i ograniczania ubytków mięsa. Z kolei dojrzewanie na sucho pozwala uzyskać wołowinę o unikatowej smakowitości. Celem niniejszego opracowania było omówienie stanu wiedzy, na podstawie przeglądu literatury, na temat charakterystyki profilu smakowo-zapachowego wołowiny dojrzewającej na sucho oraz przedstawienie potencjalnych prekursorów i kluczowych związków odpowiedzialnych za jej swoisty profil. Smakowitość jest jedną z najważniejszych cech jakości mięsa wołowego, będącą kompleksowym wrażeniem odbieranym przez zmysły smaku i zapachu. Surowe mięso ma bardzo słaby aromat i smak, ale zawiera wiele prekursorów, które są generowane w procesie dojrzewania. To właśnie te związki (pochodzące zarówno z tkanki mięśniowej, jak i tkanki tłuszczowej) w trakcie obróbki cieplnej tworzą charakterystyczny profil smakowo-zapachowy wołowiny. Z badań dotyczących smakowitości mięsa wołowego wynika, że surowiec poddawany dojrzewaniu na sucho jest pod względem tej cechy oceniany wyżej od dojrzewającego na mokro. Cechy smakowo-zapachowe takiej wołowiny opisywane są jako mocne, maślane, orzechowe, wołowe, pieczeniowe czy skarmelizowane. Dotychczas nie zidentyfikowano unikatowych związków smakowo-zapachowych, które różniłyby dojrzewanie na sucho od dojrzewania na mokro, ale wiele z tych substancji występuje w wołowinie dojrzewającej na sucho w większych ilościach. Aktywne smakowo i zapachowo związki obecne w wołowinie dojrzewającej tym sposobem obejmują spektrum substancji, a do najważniejszych należą związki: siarki, karbonylowe (aldehydy, ketony), heterocykliczne zawierające azot (pirazyny) oraz związki rozpuszczalne w wodzie (zwłaszcza wolne aminokwasy). Istotny jest też sposób obróbki termicznej mięsa. Proces prowadzony w niskiej temperaturze skutkuje tworzeniem produktów degradacji lipidów, podczas gdy szybkie ogrzewanie w wyższej temperaturze generuje więcej produktów reakcji Maillarda.
Wpływ preparatu z jagód acai (Euterpe oleracea) na właściwości powierzchniowe, autoagregację i tworzenie biofilmu przez bakterie z rodzaju Lactobacillus
Authors: Piekarska-Radzik Lidia , Klewicka Elżbieta
Published: October 2021

W ostatnich latach wzrosło zainteresowanie preparatami zawierającymi brazylijskie jagody acai (Euterpe oleracea). Ekstrakty z jagód acai charakteryzują się dużą zawartością związków organicznych, takich jak białka i lipidy. Uwagę zwraca się na prozdrowotne, a szczególnie przeciwutleniające właściwości tych owoców. Wysoki potencjał przeciwutleniający ekstraktów z jagód acai warunkowany jest dużą zawartością związków polifenolowych, jakie można izolować z ich miąższu. Związki polifenolowe obecne w ekstraktach roślinnych, spożywane przez ludzi i zwierzęta, w znacznym stopniu wpływają na modulację mikroflory jelitowej. W zależności od pochodzenia oraz zastosowanej dawki, mogą stawać się aktywatorami bądź inhibitorami wzrostu bakterii komensalnych. W niniejszej pracy poddano analizie wpływ preparatu z jagód acai na bakterie o potencjale probiotycznym z rodzaju Lactobacillus.

Agenda y particularización del discurso político chino: un análisis evolutivo en la guerra comercial con los Estados Unidos
Authors: Mosquera Mariano
Published: October 2021

¿Qué tendencias pueden identificarse en un análisis evolutivo sobre la agenda china en la guerra comercial con los Estados Unidos? La investigación analiza los dos documentos oficiales en la materia del gobierno de la República Popular China (de septiembre de 2018 y de junio de 2019), desde un marco teórico centrado en la racionalidad política china y en los estudios de agenda,  y con herramientas propias del análisis autómatico de textos. Se obtiene como conclusión que el discurso político chino  sostiene —como eje central— la intención de expandir el debate comercial a otros significados económicos, mantiene la crítica al proteccionismo y defiende su posición sobre la propiedad intelectual en China. Sin embargo, en el año 2019 en el discurso político chino adquieren una mayor centralidad los valores y principios cooperativos típicos de la retórica política china. Esto se destaca por sobre la estategia china de deconstrucción del discurso occidental sobre el conflicto comercial, lo cual es predominante, con abundante particularización discursiva, en el año 2018.

Dificuldades no engajamento às medidas contra a COVID-19
Authors: Pfeiffer Sandiléia , Lisboa Carolina Saraiva de Macedo
Published: October 2021

Como motivação pró-social, a compaixão tende a promover maior envolvimento em mentalidades de cuidado e ações de senso coletivo, capacidades prejudicadas pelos medos da compaixão. O estudo objetivou investigar o papel dos medos da compaixão em fatores envolvidos no engajamento às medidas de distanciamento social. 284 adultos (idade média = 36,47) responderam as Escalas de Medos da Compaixão, Escala de Dificuldades de Regulação Emocional e um questionário sobre engajamento aos protocolos contra a COVID-19. Um modelo de path analysis explicou 32% da variância na adesão aos protocolos por duas vias: o medo de ser compassivo por outros diminui o engajamento por motivações pró-sociais; enquanto os medos de expressar compaixão por si e outros predizem maiores dificuldades de regulação emocional, diminuindo a aderência por exaustão emocional. Oportunizar o desenvolvimento da compaixão pode contribuir para um enfrentamento mais saudável às dificuldades emocionais suscitadas pela pandemia e no envolvimento em ações coletivas.

Purpose: to describe a series of cases of older people with a clinical diagnosis of mild cognitive impairment or dementia at elderly long-term residences using virtual reality as cognitive rehabilitation.Methods: this study is a series of cases. Older adults diagnosed with mild cognitive impairment or dementia were included. Elderly people with visual and/or hearing problems that made it impossible to carry out the training were excluded. The same tests were used after intervention and at follow up after 15 days.Results: final sample consisted of 13 women and the mean age was 81.77 years (± 6.94). Patients were divided into 2 groups: mild cognitive impairment group and the dementia group. According to the therapeutic objectives aimed at improving fluency, among the results, the improvement in the scores to the group mild cognitive impairment stands out for the phonemic verbal fluency tests 23.63 (± 12.72) pre-test and 29.50 (± 11.14) post-test. There was an improvement in mild cognitive impairment group scores for the phonemic verbal fluency tests 23.63 (± 12.72) pretest and 29.50 (± 11.14) post-test. In the dementia group, test scores were 10 (± 5, 47) pretest and 12.80 (± 5.72) post-test. On the semantic verbal fluency test, the mild cognitive impairment group showed improvement 11.00 (± 3.62) pretest and 13.88 (± 6.03) post-test, while the dementia group test scores were 7.60 (± 4.56) pretest and 8.20 (± 5.12) post-test.Conclusion: regarding phonemic verbal fluency, virtual reality may be a good resource for improving the performance of older adults with mild cognitive impairment. Results were not maintained in the medium term, showing the importance of continual training.

Introducción: Los estudios dendrocronológicos en México se han basado principalmente en las coníferas, mientras que las especies de madera dura han sido poco estudiadas. Este ha sido el caso del género Quercus, con una alta diversidad taxonómica en el país pero que no ha sido estudiado con fines dendrocronológicos, a pesar de los valores ecológicos y económicos de sus especies. Objetivo: En la presente investigación se determinó el potencial dendroclimático de Quercus sideroxyla en el noroeste de México, y su relación con variables climáticas como precipitación y temperatura. Métodos: La investigación se desarrolló en el estado de Durango en el ejido Chavarría Viejo en las coordenadas (23º43’ N & 105º33’ W), se recolectaron muestras de 5 a 7 cm en dos sitios bajo aprovechamiento forestal y se procesaron mediante técnicas dendrocronológicas convencionales. Resultados: Se desarrolló una cronología de ancho de anillo total, la cual se compuso por 30 muestras de 16 árboles para el período de 1917 a 2018 (101 años). Se obtuvieron valores de intercorrelación entre series de 0.43, de sensibilidad media de 0.36, relación señal-ruido de 3.53 y autocorrelación de primer orden (0.58). En cuanto a la relación clima-crecimiento, los valores de índice de ancho de anillo se correlacionaron con datos de la estación climática más cercana al sitio de estudio; donde la precipitación invierno-primavera (enero-mayo) fue la variable de mayor influencia en el crecimiento de la especie. Conclusiones: Con base en los parámetros dendrocronológicos se demuestra el alto potencial de la especie para ser empleada en estudios dendroclimáticos en la región, la respuesta de la especie a la precipitación es similar al de las coníferas con las que cohabita.
