Ethnogastronomy: A brief exploratory review
Authors: Panetta Monica Helena , de Mattos Jorge Luiz Schirmer , Lira Wagner Lins
Published: September 2022

The increase in the interest in gastronomy indicates research' possibilities that consider food as a central theme, exploring cultures and traditions. In this sense, symbolic aspects, tastes, habits, rules, taboos and rituals point out that eating is more widespread than just the nutritional interest. Ethnoscience studies the human population’s knowledge, encompassing several fields like ethnogastronomy. This field interests itself in ethnographic investigations in order to document and value the knowledge, wisdom and eating habits of the traditional peoples and, likewise, to positively appreciate their know-how, integrating with the traditions, protecting their culture and cooperating with the preservation of the environment. In these terms, bibliographical research was performed on Scielo, Google Scholar and Brazilian Digital Library for Theses and Dissertations, platforms looking for the following items: “ethnogastronomy”, “traditional peoples” and “food culture”. Eight works were selected that show the act of eating and more complex and broad factors like the cultivation, harvesting, cooking, presentation and serving of the food. It is essential the power of tradition ahead of the preparation of “caiçaras recipes” and that Campesinos protect the important bicultural patrimony, with knowledge of practices of agroecological basis and gastronomic culture. However, we observed that few were the works found, indicating a shortfall of research in these areas, besides showing the necessity of bigger studies, registers and valorisation of traditional eating habits, as well as its social relevance both in terms of feeding sovereignty and the preservation of the environment.

Published: September 2022

Abstract: Social media is critical in today's world for exchanging information and disseminating ideas. A person's emotional impact has a significant impact on their day-to-day life. Sentiment analysis is a form of text mining that locates and pulls out subjective information from sources, allowing a company to track discussions online and monitor social sentiment about their brand, product, or service. Simply put, sentiment analysis helps determine the author's attitude towards a topic. Positive, neutral, or negative pieces of writing are classified by sentiment analysis software. Deep learning algorithms and various functions of natural language processing helps to interpret the written or spoken sentiments regarding a topic. An ecosystem where millions of bytes of data are produced daily has enabled sentiment analysis to be a key tool for interpreting these huge chunks of data. The purpose of this work is to conduct a sentiment analysis on "tweets" by making use of a variety of machine learning algorithms. The study will make an attempt to categorise the polarity of the tweet as either positive, negative, or neutral. In the event that a tweet has only positive, negative, or neutral components, the label assigned to the tweet will be determined by the sentiment that predominates.

Published: September 2022

The study analyzed the effects of changing economic and demographic variables such as population, interest rate and consumer price index on house brokerage markets by focusing on gradually sluggish housing markets in Jeollabuk-do For methods, a time series multiple regression analysis using Vector Error Correction Model (VECM) was employed in that the number of house brokerage and input variables have characteristics observed in a time series way. This study suggested the improvement schemes of housing brokage market as follows; First, it is necessary to take into account regional differences in terms of population movement, outflow, inflow and aging. Second, house brokerage markets in local cities are affected by gross regional domestic product and consumer price index so that it is important to take a look at changing commodity price as well as varying economic situation. As the patterns of economic development vary according to regions, it is necessary to consider this point from which house brokerage markets could be immensely affected.
Third, the need to forecast the potential effects of urban regeneration new deal projects underway on house brokerage markets should be considered given regional differences.
Lastly, the recession of house brokerage markets can be seen as natural as its value as investment goods is underrated in that there is a right balance between demand and supply of houses in economically advanced South Korea. Against this backdrop, developing both house brokerage markets and real estate management markets will be an important breakthrough like advanced countries.

The impact of the COVID 19 pandemic on peer to peer accommodation businesses: The case of Airbnb
Authors:   Marketing Department, Kozminski University, Warsaw, Poland, Kiczmachowska Ewa E.
Published: September 2022

Aim/purpose – This study aims to examine the impact of the COVID-19 pandemic on peer-to-peer accommodation (P2PA), investigate the potential factors related to or- ganizational resilience based on resilience resources and consumer threat response frameworks, and revisit the tourism disaster management framework. Design/methodology/approach – The operational Key Performance Indicators (KPIs) were analyzed in relation to host professionalism (organizational resilience) and property exposure to social contact (consumer threat response) for 23,334 properties available via the Airbnb platform. A regression model was proposed to estimate the impact of government policies on P2PA business performance. Findings – The revenue, the occupancy rate, and the number of active properties decreased by –59.1%, –41.3%, and –20.4%, respectively. Professional hosts and proper- ties offering less social contact showed lower declines in revenue and occupancy rate and their proportion in properties that survived 12 months after the pandemic breakout was higher. The consecutive waves of COVID-19 infections created a need to include a repetitive exchange of emergency and intermediate stages before the recovery stage could be started. Research implications/limitations – For P2PA hosts, this study could serve as a useful contribution to shaping their tactics given the COVID-19 pandemic continuation or simi- lar disaster to happen in the future. For governments or local authorities, this study should contribute to a better understanding of the impacts of various types of restrictions on accommodation segment performance. The limitation of this research is that it refers to big cities, extending it to rural destinations might reveal valuable insights. Additional- ly, it would be interesting to compare P2PA performance with other segments of the hospitality sector (e.g., hotels). Originality/value/contribution – This study contributes to the knowledge of tourism disaster management, organizational resilience, and consumer threat response frame- works. It reveals potential factors related to property resilience in the face of disease- -related disasters and proposes a revised framework for tourism disaster management. Keywords: peer-to-peer accommodation, Airbnb, revenue, tourism disaster manage- ment, COVID-19 pandemic. JEL Classification: M10, M39, L11, L25, D22.
La creación y el consumo de contenido online a partir de las emociones positivas de los consumidores: estudio de caso
Authors: Otero-Gómez María Cristina , Giraldo-Pérez Wilson
Published: September 2022

El propósito de este artículo fue analizar si las emociones positivas del consumidor están relacionadas significativamente con el boca a boca electrónico, la defensa de la marca y la resistencia a la información negativa en el contexto de los medios sociales. El estudio fue aplicado a un segmento de consumidores jóvenes que visitan un lugar de entretenimiento nocturno que favorece la realización de actividades recreativas y, por consiguiente, promueve el desarrollo de emociones positivas como la alegría, el amor y el orgullo. Se diseñó una encuesta en línea a través de Facebook que permitió la recolección de 473 cuestionarios válidos. La investigación se realizó con un enfoque cuantitativo, mediante los modelos que utilizan las ecuaciones estructurales a partir de los mínimos cuadrados parciales (PLS-SEM). Los resultados empíricos mostraron que las emociones positivas de los usuarios influyen en mayor medida en la resistencia a la información negativa. De esta manera, los consumidores rechazaron los cometarios en línea que criticaban su marca. Se concluye que la emoción que más aporta en la creación y consumo de contenido online es la alegría. Asimismo, se establece que la relación entre las emociones positivas y la creación/divulgación de contenido online tiene diferentes respuestas cuando es moderada por el comportamiento activo o pasivo del consumidor. En el caso del boca a boca electrónico, no existen diferencias significativas entre los participantes. Caso contrario sucede con la defensa y la resistencia a la información negativa, debido a que los consumidores activos demuestran una mayor disposición a interactuar a través del social media.

Published: September 2022

Las redes sociales son espacios de socialización e interacción, y tienen, dentro de sus muchas características, la posibilidad de que las personas se expresen y hagan referencia a la cotidianidad de sus vidas. Por tal motivo, durante el confinamiento por la pandemia de la COVID 19, muchas personas encontraron en las redes sociales espacios alternos de socialización y entretenimiento. De esta forma, las marcas ampliaron su marco de acción hacia el marketing digital, siendo las redes sociales las de mayor interacción por parte de los usuarios y el espacio ideal para propiciar la comercialización de bienes y servicios. El objetivo de esta investigación fue identificar los segmentos por estilo de vida de los centennials usuarios de TikTok y su percepción frente a la publicidad en dicha red social. Se tomó como referencia la segmentación psicográfica y se desarrolló un cuestionario que indagó las actividades, intereses y opiniones, el cual se aplicó a 226 usuarios activos de TikTok durante el periodo de confinamiento por COVID 19. Por medio de la metodología de clústeres jerárquicos se identificaron tres segmentos, así como los aspectos asociados a la percepción frente a la publicidad en la red social, considerándola irrelevante, poco apropiada, repetitiva e invasiva, lo que se convierte en una oportunidad para plantear y ejecutar estrategias de contenido publicitarias con impactos diferentes de acuerdo con el segmento.

Published: September 2022

El propósito de este artículo fue identificar los determinantes de la estructura de capital para el sistema bancario de El Salvador, Guatemala y Panamá en el período de 2015-2019, en el que se analizaron, específicamente, 68 instituciones bancarias que mensualmente reportan sus estados contables a las superintendencias financieras locales. Con esa finalidad, se realizó un diseño metodológico mixto, aplicando, mediante una revisión de literatura extensa, una recolección teórica y empírica de los principales postulados alrededor del tema, en el que además se analizó, por medio de un enfoque cuantitativo, la evolución de cada uno de los sistemas bancarios y su comportamiento estructural de capital. Para esto se hizo un estudio descriptivo de datos, así como el desarrollo econométrico de un modelo de datos de panel estático con efectos fijos. Los resultados obtenidos permiten identificar que los determinantes tradicionales que explican la estructura de capital de las firmas no financieras también son significativos en el contexto bancario, y que su relación con la capacidad de endeudamiento logró ajustarse al planteamiento de la teoría de la jerarquización financiera.
Corporate governance and the Dodd-Frank $10B threshold
Authors: Swanstrom Mark
Published: September 2022

The financial crisis of 2007–2008 resulted in major changes to the financial industry including the passage of the Dodd-Frank Act in 2010. While the emphasis of Dodd-Frank was on systematically important banks that are “too big to fail”, the act also placed several conditions on financial institutions with assets greater than $10B. Hogan and Burns (2019) show that Dodd-Frank imposed higher non-interest expenses on financial institutions, especially smaller institutions. Bouwman, Hu, and Johnson (2018) look at how financial institutions modified their behavior following passage including delaying crossing the threshold. Agrawal and Knoeber (2001) find that firms in more regulated industries are more likely to have politically connected board members. This article examines whether the corporate governance of financial institutions with assets just below the $10B asset threshold affected their willingness to cross that threshold. Results indicate that firms with staggered boards and smaller boards took longer to cross the threshold while higher levels of ownership by the chief executive officer (CEO) resulted in faster crossings. Financial institutions were much quicker to pass the threshold in the later years of the study due to changes in the economic and regulatory environment.
Geobacter sulfurreducens metabolism at different donor/acceptor ratios
Authors: Frühauf-Wyllie Hanna Marianne , Holtmann Dirk
Published: September 2022

Geobacter species have great application potential in remediation
processes and electrobiotechnology. In all applications, understanding
the metabolism will enable target-oriented optimization of the
processes. The typical electron donor and carbon source of the Geobacter
species is acetate, while fumarate is the usual electron acceptor. Here,
we could show that depending on the donor/acceptor ratio in batch
cultivation of G. sulfurreducens different product patterns occur. With
a donor/acceptor ratio of 1:2.5 malate accumulated as an intermediate
product but was metabolized to succinate subsequently. At the end of the
cultivation, the ratio of fumarate consumed and succinate produced was
approximately 1:1. When fumarate was added in excess, malate accumulated
in the fermentation broth without further metabolization. After the
addition of acetate to stationary cells, malate concentration decreased
immediately and additional succinate was synthesized. Finally, it was
shown that also resting cells of G. sulfurreducens could efficiently
convert fumarate to malate without an additional electron donor.
Overall, it was demonstrated that by altering the donor/acceptor ratio,
targeted optimization of the metabolite conversion by G. sulfurreducens
can be realized.
MDT practice determines treatment pathway for patients with advanced ovarian cancer: a multi-centre observational study
Authors: Khassan Tamara , Smitten Emily , Wood Nicholas , Fotopoulou Christina , Morrison Jo , MacDonald Madeleine , Baxter Kathryn , Edmondson Richard
Published: September 2022

Background Patients presenting with advanced ovarian cancer can be
managed in a variety of ways. No clear selection algorithms exist to
guide decision-making and there is significant geographical variation in
practice. Decision-making takes place in specialist multidisciplinary
team meetings (MDTs). We wanted to examine whether format and behaviour
within these meetings could explain the geographical variation in
treatment patterns seen in England Methods Observational study of five
cancer centre MDTs over a six-week period. Data were recorded for
overall MDT performance. The GO-MDT-MODe tool was used to provide a
measure of participation and quality of case discussion for all cases of
advanced ovarian cancer. MDT scores were correlated with surgical and
survival data extracted from national audit data. Results A total of 870
case discussions, including 145 cases of advanced ovarian cancer, were
observed. MDTs varied in structure, format and time allocation between
centres. Cluster analysis showed significant variation in quality and
participation of discussion between centres (p<0.0025) and
this correlated with the proportion of patients in the wider cancer
alliance undergoing surgery, but not with overall survival Conclusions
We have shown that at least part of the variation in practice seen in
the UK correlates with different behaviours within MDTs. Increasing time
for discussion and encouraging participation from all staff groups may
increase proportions of patients undergoing optimal treatment regimens.

Published: September 2022

Background: Pediatric CNS tumors are the leading cause of
pediatric cancer mortality. Research addressing genomic biomarkers and
clinical outcomes is needed to inform therapeutic decision making.
Methods: We conducted a retrospective analysis of pediatric
patients (age <21) diagnosed with a primary CNS tumor at four
upstate New York hospitals from 2008 to 2021. Clinical and
histopathologic data were identified from each patient, including
genomic analysis of somatic mutations and tumor mutation burden (TMB)
where available. These variables were each compared with overall
survival using cox-regression analyses. Multivariable analysis was
conducted to identify patient characteristics that may independently
predict survival. Results: We identified 119 patients. Common
tumor types included low-grade glioma (N=51), high-grade glioma (N=29),
and medulloblastoma (N=11). Common driver-mutations included TP53
inactivation (N=16), BRAF-KIAA1549 fusion (N=16), FGFR1
amplification (N=12), BRAF V600E mutation (N=12), NF1 loss
(N=12), and H3F3A K28M mutation (N=6). Median TMB was 1
mutation/megabase (mut/Mb, range=0-132). Overall survival was 79.9%.
Variables associated with poorer survival on univariable analysis were
higher TMB (p=0.002, HR 4.97), high grade tumors (p=0.009, HR 84.3), and
high-grade glioma histology (p=0.021, HR 3.14). Multivariable analyses
further identified TMB (p=0.011, HR 4.46) and high-grade histology
(p=0.015, HR 5.28) as independently predictive of worse survival. Tumor
progression was more common in high TMB (N=15, 44%) than in low TMB
tumors (N=19, 35%). Conclusions: High TMB is correlated with
higher rates of progression and death as compared to low TMB tumors.
These findings may help identify patients who may benefit from
alternative treatments, such as immunotherapies.
Adverse Childhood Experiences (ACEs) and Resilience in Childhood and Adolescent/Young Adult (AYA) Cancer Patients
Authors: Schwartz Lindsay F. , Tan Marcia M. , McCrae Julie S. , Burkhardt Tiffany , Ness Kirsten , Henderson Tara
Published: September 2022

Childhood and adolescent/young adult (AYA) cancer survivors experience
poor health outcomes in adulthood. Adverse Childhood Experiences (ACEs)
also portend poor health outcomes for the general population. Resilience
can mitigate effects of ACEs. We examined the feasibility of assessing
ACEs and resilience in childhood/AYA cancer patients. We also described
occurrences of ACEs, resilience, and poor health outcomes. Of 52
participants, most rated their study experience favorably, with privacy
in answering sensitive questions. Half reported ACEs, and those with
ACEs had lower resilience, X(3,N=52)=9.39,
p=0.02. Further investigations of ACEs and resilience in larger
cohorts are warranted to delineate associations with long-term health
outcomes.

Silica aerogel is a new porous functional material composed of SiO2
particles. In this paper, silica aerogel was prepared by acid-base
two-step sol-gel method without solvent replacement and surface
modification using water/ethanol/n-hexane surfactant-free
microemulsion(SFME) as solvent. The samples were characterized and
analyzed by SEM, FT-IR, XRD, BET, TG-DSC, thermal conductivity, and
hydrophobic angle. The results showed that when the molar ratio of TEOS,
MTES, H2O, EtOH, n-hexane, octyltriethoxysilane, and DEDMS was 0.25:
0.75: 12: 10: 0.1: 0.07: 0.08, the density of silica aerogel in the SFME
system was 0.157 g/cm3, the porosity was 93%, the average pore diameter
of BJH was 3.92 nm, the average particle size was 15.78 nm, the
hydrophobic angle was 152.5°, and the thermal conductivity was 0.0522
W/(m·K). It can maintain good hydrophobicity below 240.5 ℃.
Hydrophobicity completely disappears when the temperature exceeds 510
°C.
Global transcriptome and gene co-expression network analyses reveal regulatory and non-additive effects of drought and heat stress in grapevine

Published: September 2022

Despite frequent co-occurrence of drought and heat stress, the molecular
mechanisms governing plant responses to these stresses in combination
have not often been studied. This is particularly evident in non-model,
perennial plants. We conducted large scale physiological and
transcriptome analyses to identify genes and pathways associated with
grapevine response to drought and/or heat stress during stress
progression and recovery. We identified gene clusters with expression
correlated to leaf temperature and water stress and five hub genes for
the combined stress co-expression network. Several differentially
expressed genes were common to the individual and combined stresses, but
the majority were unique to the individual or combined stress
treatments. These included heat-shock proteins, mitogen-activated
kinases, sugar metabolizing enzymes, and transcription factors, while
phenylpropanoid biosynthesis and histone modifying genes were unique to
the combined stress treatment. Following physiological recovery,
differentially expressed genes were found only in plants under heat
stress, both alone and combined with drought. Taken collectively, our
results suggest that the effect of the combined stress on physiology and
gene expression is more severe than that of individual stresses, but not
simply additive, and that epigenetic chromatin modifications may play an
important role in grapevine responses to combined drought and heat
stress.

Android has become the most popular smartphone operating system. This
rapidly increasing adoption of Android has resulted in significant
increase in the number of malwares when compared with previous years.
There exist lots of antimalware programs which are designed to
effectively protect the users’ sensitive data in mobile systems from
such attacks. In this paper, our contribution is twofold. Firstly, we
have analyzed the Android malwares and their penetration techniques used
for attacking the systems and antivirus programs that act against
malwares to protect Android systems. We categorize many of the most
recent antimalware techniques on the basis of their detection methods.
We aim to provide an easy and concise view of the malware detection and
protection mechanisms and deduce their benefits and limitations.
Secondly, we have forecast Android market trends for the year up to 2018
and provide a unique hybrid security solution and take into account both
the static and dynamic analysis an android application.
Synthesis and structural characterization of Cd(II) complexes with 2-acetylpyridine-aminoguanidine - a novel coordination mode

Published: September 2022

The structures of the first two complexes with bidentate coordination of aminoguanidine Schiff base, i.e., 2-acetylpyridine-aminoguanidine (L), are reported. The complex of the formula [Cd2Cl6(HL)2] (1) was obtained in the reaction of warm aqueous solutions of chloride salts of Cd(II), Zn(II) and the ligand, while the reaction of cadmium bromide and the ligand in the presence of deprotonating agent as well as ammonium thiocyanate resulted in the formation of the complex in which Schiff base has both the role of the ligand and the counterion, viz., [HL][Cd(HL)(NCS)2XY]?H2O (2), where X is Cl- or Br-, and Y Br- or SCN-. The complexes were characterized by IR spectroscopy, elemental analysis, conductometric measurements and single crystal X-ray diffraction. The unusual bidentate coordination of the Schiff base lead to significant changes in the geometry of this molecule (from almost planar in free form and as a tridentate ligand to twisted as a bidentate ligand). Besides, in complex 1 relatively rare bridging coordination of Cl- in octahedral Cd(II) is found, while the crystal structure of complex 2 exhibits substitutional disorder, and contains four different anions: [Cd(HL)(NCS)2Br(SCN)]- (ca. 61 %), [Cd(HL)(NCS)2Cl(SCN)]- (ca. 35 %), [Cd(HL)(NCS)2Br2]- (ca. 3 %) and [Cd(HL)(NCS)2ClBr]- (ca. 1 %).

OBJECTIVE

We investigated if women with gestational diabetes mellitus (GDM) in the third trimester of pregnancy exhibit adverse cardiac alterations in myocardial energetics, function, or tissue characteristics.

RESEARCH DESIGN AND METHODS

Thirty-eight healthy, pregnant women and 30 women with GDM were recruited. Participants underwent phosphorus MRS and cardiovascular magnetic resonance for assessment of myocardial energetics (phosphocreatine [PCr] to ATP ratio), tissue characteristics, biventricular volumes and ejection fractions, left ventricular (LV) mass, global longitudinal shortening (GLS), and mitral in-flow E-wave to A-wave ratio.

RESULTS

Participants were matched for age, gestational age, and ethnicity. The following data are reported as mean ± SD. The women with GDM had higher BMI (27 ± 4 vs. 33 ± 5 kg/m2; P = 0.0001) and systolic (115 ± 11 vs. 121 ± 13 mmHg; P = 0.04) and diastolic (72 ± 7 vs. 76 ± 9 mmHg; P = 0.04) blood pressures. There was no difference in N-terminal pro-brain natriuretic peptide concentrations between the groups. The women with GDM had lower myocardial PCr to ATP ratio (2.2 ± 0.3 vs. 1.9 ± 0.4; P < 0.0001), accompanied by lower LV end-diastolic volumes (76 ± 12 vs. 67 ± 11 mL/m2; P = 0.002) and higher LV mass (90 ± 13 vs. 103 ± 18 g; P = 0.001). Although ventricular ejection fractions were similar, the GLS was reduced in women with GDM (−20% ± 3% vs. −18% ± 3%; P = 0.008).

CONCLUSIONS

Despite no prior diagnosis of diabetes, women with obesity and GDM manifest impaired myocardial contractility and higher LV mass, associated with reductions in myocardial energetics in late pregnancy compared with lean women with healthy pregnancy. These findings may aid our understanding of the long-term cardiovascular risks associated with GDM.
Philosophy of Censorship and Safety in Libyan Cinema: Before and After the Libyan Uprising
Authors: Abuaniza Abdulhamid
Published: September 2022

This research examines the problem of censorship in the Libyan context from a historical and ideological standpoint. Libyan cinema has not gotten as much academic attention as Middle Eastern nations like Egypt, Syria, Lebanon, and Palestine. In addition to providing a historical overview of Libyan cinema, this study carefully investigates the settings that influenced Libyan national cinema from the perspectives of people who work in this industry there. To learn more about the problems with censorship in Libyan cinema before and after 2011, 25 individuals were interviewed informally between July 2018 and February 2019. Twenty-five people were the maximum because many were reluctant to give interviews due to safety concerns, which participants also mentioned. Data analysis was done using Nvivo 14. The data gathered identified two problems—safety and censorship—that have long plagued Libyan cinema. All panelists agreed that the Libyan film industry needs to advance in governing authorities, censorship, inventiveness, and how films engage with society's members.

En el siguiente trabajo, se aborda el I Congreso Femenino Radical, realizado en la ciudad de Córdoba (Argentina) en 1949, como un evento que permite examinar la agenda de las mujeres radicales, iluminando aspectos sobre la organización y disputas del movimiento femenino de la Unión Cívica Radical, el principal partido opositor en el primer peronismo. La revisión de este encuentro permite repensar ese juego entre género y ciudadanía, poniendo en el centro de la escena los debates sobre los límites entre lo femenino y lo masculino, lo público y lo privado, en un momento de fuertes cambios en el orden social/ sexual, iluminados a partir de este acontecimiento. Esta reconstrucción historiográfica parte de la relectura novedosa de un corpus tradicional, conformado por la prensa local, y habilitada por las claves conceptuales indicadas, a través de una observación documental eminentemente cualitativa.

Aims

Telemedicine may be of benefit in patients with heart failure (HF), although virtual visits are often carried out on an ad hoc basis. Herein, we discuss a structured protocol that defines all the steps needed for virtual visits, LEAP Virtual Visit, which includes guides and support kits for clinicians and patients.

Methods

A working group of clinicians was established to develop a protocol for virtual visits. The virtual model for monitoring HF patients was based on measurement and sizing of patient flows, type of services, and critical organizational points. The process of virtual visits was broken down to identify the specific activities, players, roles, and support tools needed for implementation in daily practice.

Results

In the protocol developed, sections were included on patient eligibility, exams, supportive tools, and practical organizational aspects. IT requirements were also considered and the most widely used teleconference platforms were compared according to features that were considered to be priority for virtual visits. Protocols and support kits were developed, including guides for clinicians and patients, two questionnaires to assess the level of satisfaction, patient diary, disease awareness brochure, and template to monitor key performance indicators. The phases include an enrolment phase, document sharing phase, pre-evaluation phase, the virtual visit itself, and the post-visit phase. The protocol for the virtual visit was divided into 8 sequential steps to be carried out between the clinic and patient/caregiver.

Conclusion

The protocol described can be expected to have a number of benefits for the patient, clinic, and healthcare structure.

Background

Atrial fibrillation catheter ablation (AFCA) should be considered as a strategy to avoid pacemaker (PM) implantation for patients with bradycardia–tachycardia syndrome (BTS), but lack of evidence is remarkable.

Methods

Our aim was to conduct a random-effects model meta-analysis on safety and efficacy data from controlled trials and observational studies. We compared atrial fibrillation (AF) recurrence, AF progression, procedural complication, additional procedure, cardiovascular death, cardiovascular hospitalization, heart failure and stroke in patients undergoing AFCA vs. PM implantation.

Results

PubMed/MEDLINE, Cochrane Database and Google Scholar were screened, and four retrospective studies were selected. A total of 776 patients (371 in the AFCA group, 405 in the PM group) were included. After a median follow-up of 67.5 months, lower AF recurrence [odds ratio (OR) 0.06, confidence interval (CI) 0.02–0.18, I
2 = 82.42%, P < 0.001], AF progression (OR 0.12, CI 0.06–0.26, I
2 = 0%, P < 0.001), heart failure (OR 0.12, CI 0.04–0.34, I
2 = 0%, P < 0.001), and stroke (OR 0.30, CI 0.15–0.61, I
2 = 0%, P = 0.001) were observed in the AFCA group. No differences were observed in cardiovascular death and hospitalization (OR 0.48, CI 0.10–2.28, I
2 = 0%, P = 0.358 and OR 0.43, CI 0.14–1.29, I
2 = 87.52%, P = 0.134, respectively). Higher need for additional procedures in the AFCA group was highlighted (OR 3.65, CI 1.51–8.84, I
2 = 53.75%, P < 0.001). PM implantation was avoided in 91% of BTS patients undergoing AFCA.

Conclusions

AFCA in BTS patients seems to be more effective than PM implantation in reducing AF recurrence and PM implantation may be waived in most BTS patients treated by AFCA. Need for additional procedures in AFCA patients is balanced by long-term benefit in clinical end points.

Aims

This meta-analysis aims to compare direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) in the setting of left ventricular thrombosis (LVT).

Method and Results

We systematically searched MEDLINE, Cochrane Library, Biomed Central and Web of Science for trials comparing DOACs versus VKAs in the setting of LVT and reporting outcome data on thrombosis resolution, stroke and bleeding. Fourteen studies were finally selected. The Mantel-Haenszel method with a random effect model was used for the pooled analysis. The primary outcome was the occurrence of LVT resolution. The secondary outcomes were the occurrence of stroke or bleeding during treatment. One thousand three hundred and thirty-two patients were included in the analysis for the primary outcome. Of these, 424 were treated with DOACs and 908 with VKAs. The pooled odds ratio (OR) for the primary outcome was 1.00 [95% confidence interval (95% CI) 0.77–1.31, I

2
0.0%], reflecting equal effect in terms of thrombus resolution. Overall, 2290 patients, 608 on DOACs and 1682 on VKAs were included in the analysis of stroke occurrence, showing reduced risk of events in patients treated with DOACs (pooled OR 0.58, 95% CI 0.36–0.93; I

2
0.0%) as well as for bleeding occurrence (number of patients included 2139; pooled OR 0.64, 95% CI 0.44–0.94; I

2
0.0%).

Conclusion

Compared with VKAs, we found DOACs to have similar efficacy on thrombus resolution and favorable effects on stroke reduction and bleedings. DOACs should be considered as an alternative treatment for LVT. Large prospective randomized clinical trials are needed to confirm this exploratory finding.

The state of soils was presented in the aspect of environmental protection when using acidified slurry was used as fertilizer to protect ammonia from escaping into the atmosphere. The use of concentrated sulfuric acid to lower the pH of the slurry and thus retain nitrogen in the soil and then use it by crops gives a double benefit, reduces nitrogen losses, and reduces the cost of mineral fertilizers that should be purchased. Injecting raw slurry below the surface of the soil has some benefits in the form of reducing ammonia emissions, but it does not affect the use of fertilizers with the addition of sulfur, which is ensured in the case of acidification of the slurry. Additional benefit is to obtain environment protection. Leaching of elements from grassland and corn crop soil treated with raw cattle slurry and acidified cattle slurry (m3·ha−1) was presented. The K content was highest in the leachate collected after the application of the last batch of acidified slurry. Yield tests were conducted on similar soils as presented in the tables for grass, using six 500 m2 plots with corn, cultivar ES Cirrus, with acidified slurry and one test plot with non-acidified slurry. Analysis of variance and significant difference among the treatment means were separated using Duncan’s Multiple Range Test (DMRT) at a probability level of 0.05. Based on statistical analysis, it was demonstrated that crop yields of corn grain increased when fertilized with acidified slurry, at an average of 4 t·ha−1. During field tests corn crop yield varied from 14 t·ha−1 to 18 t·ha−1 when non-acidified and acidified slurry were used. The yield on the grassland was approx. 30 t·ha−1. The soil sorption complex, in combination with its buffer properties and acidification, did not affected the pH value. This makes the acidification process safe for plants and for the soil environment.
Temporary international migration, shocks and informal finance: analysis using panel data
Authors: Chakraborty Tanika , Pandey Manish
Published: September 2022

We examine households’ temporary international migration response when faced with shocks in rural Kyrgyzstan. Using a household fixed effects model, we find that while a drought shock increases migration, a winter shock reduces migration. We argue that this difference is because of the trade-off between two effects of a shock for a household: loss of income and increase in the need for labor services. Migration increases when the former effect of a shock dominates and it reduces when the latter effect dominates. We explore these mechanisms further, and find that when households have easier access to informal finance the migration response is muted only for shocks for which the adverse income effect dominates. These findings provide evidence in favor of our proposed mechanisms through which shocks affect migration.

Fiscal policy has been used by various governments to promote economic growth. The effectiveness of government expenditure on economic growth depends on recipient sector of government expenditure. This study contributes to this research area by investigating the effect of government agricultural expenditure on economic growth in the Kingdom of Lesotho. The government of Lesotho identified the agricultural sector as a productive sector that is central to the achievement the economic growth goal and development plan. Descriptive statistics and inferential econometric techniques (ARDL, DOLS and VEC Granger causality) over time-series data for the period 1982-2019 were utilized in this study. The results suggest that while current level and pattern of government agriculture expenditure cannot stimulate the desired economic growth and prosperity in the country, domestic investment appear to be a stimulant of the desired economic prosperity. Consequently, any economic growth policy or strategy that is premised on government agricultural sector expenditure would fail. Thus study recommends that countries including Lesotho should prioritize sustained increase in domestic investment.
«Evil for evil to die»: punishments of the ancient russian bishops (experience of a church judge of the XI - beginning of the XIV centuries)
Authors: Gaidenko P. I.
Published: September 2022

With all the attention of Russian historiography to the life of ancient Russian bishops, the problem of punishing bishops did not often attract the attention of researchers. If there was any interest in the noted topic, it was mainly within the framework of individual plots. However, a comprehensive consideration of the problem of punishment of ancient Russian bishops of the XI - the first quarter of the XIV was not carried out. Meanwhile, an analysis of the sources allows us to conclude that, for all the height of their ministry, the ancient Russian bishops not only regularly found themselves in the face of various courts, but were also subjected to various punishments, both ecclesiastical and those that took place in the practice of Byzantium and Russia. Within the framework of the presented article, an attempt was made to systematize the various punishments applied to bishops in the 11th - first quarter of the 14th centuries. The author comes to the conclusion that, despite their high status, the ancient Russian bishops were regularly subjected to various punishments. These punishments were not always fair. However, we can confidently say that the legal culture within the church was explained by the strong influence of Byzantine legal traditions. From a canonical point of view, punishments were far from always justified. But even in this case, the Old Russian scribes perceived them as corresponding to the realities of Old Russian reality and even fair.
