Published: December 2022

In implementing the 4.0 marketing strategy, micro, small and medium business actors need to be open to market changes and be willing to allocate funds for marketing activities. This study aims to analyze the effect of innovation mediation on the relationship between programs and performances on the competitive advantage of SMEs. This study's research method includes library and field research design with a quantitative approach. This study's research subjects were SMEs in Indonesia's culinary sector. Data collection techniques using observation, interviews, questionnaires, and documentation. The data analysis method used is Partial Least Square (PLS). The data analysis test tool uses the Smartpls statistical software. The study's results stated that programs and performance positively and significantly affected innovation. The results of further research confirm that programs and performance positively and significantly affect competitive advantage. Further results conclude that innovation can mediate the relationship between programs and performance on competitive advantage. The conclusion of this study explains that to encourage a sustainable competitive advantage to be different from competing products, MSME actors need to start with a new marketing strategy in providing solutions when selling products to consumers and being able to design content relevant to product branding.
Emerging Corporate Reporting Perspectives and Operational Performance of Listed Oil and Gas Firms in Nigeria
Authors: Ifedigbo  , Onyemaechi Samuel
Published: December 2022

The study examined emerging corporate reporting perspectives and operational performance of listed oil and gas firms in Nigeria. The study adopted a mixed research method using both correlation and causal research design in analyzing the data of the 7 (Sampled) listed Oil and Gas firms from 2011-2020. Findings revealed that there exists a positive weak relationship between sustainability disclosure and sales performance of the listed Oil and Gas firms in Nigeria. But sustainability cost has a strong positive relationship with sales performance of the listed Oil and Gas firms in Nigeria. Based on the findings, we conclude and recommend that listed Oil and Gas firms in Nigeria should adopt the recommendation made by GRI to report seprately sustainability performance of the firms outlining the cost implication for being environmetally, socially and economically responsible. This will signal the ethical concerns of the firms to the various stakeholders thus, increase the patronage of their products and in turn increase the firms sales. It was further recommended that listed Oil and Gas firms should ensure that more figures are disclosed than relying only on letters. Figures and pictorial evidence will attract the attention of stakeholders to the sustainability disclosure items of the firms and subsequently improve the trust and patronage of the firm. The current sustainability report is lacking in this aspects, that may be the reason why the result showed a weak insignificant relationship with the sales performance of the listed Oil and Gas firms.

Authors: Haro Salazar Mario Enrique , Espinoza Alcívar Diana Piedad , Vargas Salvador Carlos Luis
Published: December 2022

La agilidad se ha convertido en una parte vital del marketing. Graves eventos pandémicos como el COVID-19 han planteado la necesidad de que las marcas se adapten, accedan y se muevan rápidamente. A medida que las condiciones económicas cambiaron drásticamente, los especialistas en marketing necesitan actualizarse, ya que las personas trabajan de forma remota y muchas empresas cambiaron para vender solo en línea. Hoy en día, las marcas deben tener la capacidad de reciclar y atraer nuevos talentos, midiendo constantemente el impacto en tiempo real, la base de consumidores debe ser monitoreada, identificada y el cambio de dirección debe realizarse de manera instantánea. Este estudio tiene como objetivo comprender el cambio de percepción de los empresarios del marketing provocado por el marketing ágil y las implicaciones futuras que puede tener en las estrategias de marketing de las empresas. El estudio ha optado por la investigación cualitativa con análisis de contenido y revisión sistemática de la literatura para conceptualizar los conceptos objeto de estudio y detallar los modelos, teorías, beneficios y estrategias. La investigación ha demostrado que el marketing ágil ha traído cambios positivos en las organizaciones debido a que pueden colaborar mejor con otras empresas, enfocarse mejor y, al mismo tiempo, fomentar innovaciones a largo plazo. Esta investigación también ha establecido el hecho de que, aunque el marketing ágil es el futuro del marketing, no puede funcionar bien hasta que las marcas y las empresas estén equipadas para manejar los cambios que trae. Esta investigación serviría de base para académicos, empresarios e investigadores.
Depth-related patterns in microbial community responses to complex organic matter in the western North Atlantic Ocean
Authors: Brown Sarah A. , Balmonte John Paul , Hoarfrost Adrienne , Ghobrial Sherif , Arnosti Carol
Published: December 2022

Abstract. Oceanic bacterial communities process a major fraction of marine organic
carbon. A substantial portion of this carbon transformation occurs in the
mesopelagic zone, and a further fraction fuels bacteria in the bathypelagic
zone. However, the capabilities and limitations of the diverse microbial
communities at these depths to degrade high-molecular-weight (HMW) organic
matter are not well constrained. Here, we compared the responses of distinct
microbial communities from North Atlantic epipelagic (0–200 m), mesopelagic
(200–1000 m), and bathypelagic (1000–4000 m) waters at two open-ocean
stations to the same input of diatom-derived HMW particulate and dissolved
organic matter. Microbial community composition and functional responses to
the input of HMW organic matter – as measured by polysaccharide hydrolase,
glucosidase, and peptidase activities – were very similar between the
stations, which were separated by 1370 km but showed distinct patterns with
depth. Changes in microbial community composition coincided with changes in
enzymatic activities: as bacterial community composition changed in response
to the addition of HMW organic matter, the rate and spectrum of enzymatic
activities increased. In epipelagic mesocosms, the spectrum of peptidase
activities became especially broad and glucosidase activities were very
high, a pattern not seen at other depths, which, in contrast, were dominated
by leucine aminopeptidase and had much lower peptidase and glucosidase rates
in general. The spectrum of polysaccharide hydrolase activities was enhanced
particularly in epipelagic and mesopelagic mesocosms, with fewer
enhancements in rates or spectrum in bathypelagic waters. The timing and
magnitude of these distinct functional responses to the same HMW organic
matter varied with depth. Our results highlight the importance of residence
times at specific depths in determining the nature and quantity of organic
matter reaching the deep sea.
Interannual variability of the initiation of the phytoplankton growing period in two French coastal ecosystems

Published: December 2022

Abstract. Decadal time series of chlorophyll a concentrations sampled at high
and low frequencies are explored to study climate-induced impacts on the
processes inducing interannual variations in the initiation of the
phytoplankton growing period (IPGP) in early spring. We specifically detail
the IPGP in two contrasting coastal temperate ecosystems under the influence
of rivers highly rich in nutrients: the Bay of Brest and the Bay of Vilaine.
In both coastal ecosystems, we observed a large interannual variation in
the IPGP influenced by sea temperature, river inputs, light availability
(modulated by solar radiation and water turbidity), and turbulent mixing
generated by tidal currents, wind stress, and river runoff. We show that the
IPGP is delayed by around 30 d in 2019 in comparison with 2010. In situ observations
and a one-dimensional vertical model coupling hydrodynamics,
biogeochemistry, and sediment dynamics show that the IPGP generally does not
depend on one specific environmental factor but on the interaction between
several environmental factors. In these two bays, we demonstrate that the IPGP
is mainly caused by sea surface temperature and available light conditions,
mostly controlled by the turbidity of the system before first blooms. While
both bays are hydrodynamically contrasted, the processes that modulate the IPGP
are similar. In both bays, the IPGP can be delayed by cold spells and flood
events at the end of winter, provided that these extreme events last several
days.
Permafrost degradation at two monitored palsa mires in north-west Finland

Published: December 2022

Abstract. Palsas and peat plateaus are expected to disappear from many regions, including Finnish Lapland. However, detailed long-term monitoring data of the degradation process on palsas are scarce. Here, we present the results of the aerial photography time series analysis (1960–2021) and annual RTK-GNSS and active layer monitoring (2007–2021) at two palsa sites (Peera and Laassaniemi) located in north-west Finland. The emphasis is on detailed change detection for the period covered by Unmanned Aerial System surveys (2016–2021) and connections to climate . At both sites, the decrease in palsa area by -77 % to -90 % since 1960 and height by -16 % to -49 % since 2007 indicate substantial permafrost degradation throughout the study periods . The area loss rates are mainly connected to winter air temperature changes at Peera and winter precipitation changes at Laassaniemi. The active layer thickness (ALT) has varied each year with no significant trend and is related mainly to snow depths and summer air temperatures at Peera. At Laassaniemi, the ALT is weakly related to climate and has been decreasing in the middle part of the palsa during the past eight years despite the continuous decrease in palsa volume. Our findings imply that the ALT in the inner parts of palsas do not necessarily reflect the overall permafrost conditions and underline the importance of surface position monitoring alongside the active layer measurements. The results also showed a negative relationship between the ALT and snow cover onset, indicating the complexity of climate–permafrost feedbacks in palsa mires.
Iron oxidation state in serpentines and magnesian chlorites of subduction-related rocks
Authors: Reynard Bruno , Fellah Clémentine , McCammon Catherine
Published: December 2022

Abstract. The ferric iron content in hydrothermally altered
ultrabasic rocks and their major minerals, serpentines and Mg-chlorites, is
important for establishing the oxidation state budget from oceanic ridges to
subduction zones, in carbonaceous chondrites, and for modeling phase
equilibria. A compilation of literature Mössbauer spectroscopic data on
serpentines and magnesian chlorites from high-pressure ophiolites yields much
lower ferric-to-total-iron ratios (Fe3+ / Fetotal) than those
obtained on similar samples by X-ray absorption near-edge spectroscopy (XANES), leading to contradictory estimates of
the ferric iron budget of subduction zones. New Mössbauer analysis of
antigorite and Mg-chlorite samples from suites of high-pressure ophiolitic
terrains of various Phanerozoic ages confirms the low and homogeneous values
previously obtained by this technique, while lizardite inherited from
oceanic hydrothermal alteration is ferric iron rich. We argue that XANES
values may be biased by photo-oxidation when samples have a high Mg content,
which is the case for serpentines and chlorites from subduction zones.
Photo-oxidation is less important in Fe-poor phyllosilicates of the mica and
talc families and does not affect the Fe-rich serpentines (greenalite,
cronstedtite) of meteorites or Fe-rich terrestrial phyllosilicates.
Mössbauer Fe3+ / Fetotal ratios of serpentine confirm the
occurrence of a major redox change at the lizardite–antigorite transition
near 300–400 ∘C rather than at the dehydration of antigorite at
500–650 ∘C in serpentinites from high-pressure ophiolites.
Impact of COVID-19 on perception and preparedness among clinical year Malaysian undergraduate dental students – A cross-sectional study
Authors: Rath Avita , Wong Li Zheng Melissa , Pannuti Claudio Mendes
Published: December 2022

This study aimed to evaluate how quarantine affected final-year dental students' self-perceptions of preparation and assess how online training affected clinical students' education at SEGi University. Year 3 to 5 students (n=140) were asked to fill up an online questionnaire. The first part included the effects of online education experience between the academic years. The second section assessed the graduating class's self-perceived readiness in cognitive, communication and professional abilities. The Chi-square test was used to analyse the association between the groups regarding academic years, gender, and family income. Year 3 students missed educational experiences during lockdown significantly more than years 4 and 5 (p<0.001). In addition, 86% of year 5 students (p< 0.001) felt that online assessment was not a suitable evaluation method compared to the other clinical years. About two-thirds of the 5th year dental students were unsure of their confidence in their skills before graduation. Around half of the final-year students said they were unsure about starting their practice following graduation. After graduation, 80% of respondents preferred to spend a year in residence with sufficient training. Although students' self-perceived preparation was generally positive, they expressed reservations about the independent practice after graduation.
European Commission as a driver of change
Authors: Keulen Sjoerd , Kroeze Ronald
Published: December 2022

By analysing the case of the closure of the Amsterdam shipyards in the 1980s, this article shows how the European Commission (EC) actively promoted a neoliberal turn in policies on state support for economic sectors in Western Europe. In addition to the EC, leading civil servants within the Dutch ministries of Economic Affairs and Finance emerged clearly as embracing neoliberal ideas early on as an answer to tackle the economic crisis of the 1970s. A third, often neglected factor in explanations for the rise of neoliberalism were management consultants – in this case from management consultancy firm McKinsey – who wrote alarming reports about the shipbuilding industry and promoted ideas that emphasized the importance of business principles and individual managers as key for improvement, thereby offering an alternative to macroeconomic Keynesian models of growth.

Tradiciones gráficas e interacción cultural: arte mueble paleolítico del interior peninsular
Authors: Ibero Álvaro
Published: December 2022

En los últimos treinta años se ha documentado un notable incremento de manifestaciones artísticas paleolíticas en el interior de la península ibérica. Esto ha permitido llenar el vacío generado más allá de las tradicionales áreas de estudio del arte paleolítico peninsular. Si bien en los años 90 la atención se centró en el fenómeno parietal al aire libre, las excavaciones realizadas han aportado nuevos datos sobre el arte mobiliar. En este trabajo se presenta una síntesis de las evidencias mobiliares paleolíticas del interior peninsular con el objetivo de reconocer dinámicas culturales de los últimos cazadores-recolectores de la península. A partir de esta síntesis se propone una interpretación en clave diacrónica de su secuencia cronológica y se plantea como hipótesis la coexistencia de dos tradiciones gráficas diferenciadas en el interior peninsular, basada en la distribución geográfica de su simbolismo y en los ritmos de interacción gráfica identificables en su arte mobiliar. El resultado muestra una tendencia a la intensificación en las relaciones culturales a medida que el Paleolítico superior alcanza sus fases terminales.
El diablo está en los detalles: nuevos datos arquitectónicos y contextuales para el pilar-estela de El Prado (Jumilla, Murcia)
Authors: Robles Moreno Jesús
Published: December 2022

En 1983 se produjo el hallazgo del pilar-estela de El Prado (Jumilla, Murcia), uno de los monumentos mejor conservados de la cultura ibérica. A pesar de esta circunstancia, el montaje y el contexto de este edificio han sido discutidos a lo largo de su historiografía. En este trabajo dichas cuestiones son revisadas, lo que ha permitido ofrecer una nueva imagen del pilar-estela, con datos arquitectónicos inéditos que aportan interesante información al debate existente sobre su restitución. Paralelamente, a través del análisis del pilar y la documentación de la campaña, se reflexiona sobre su cronología y contexto concluyendo que pudo tratarse de un monumento (funerario o no) vinculado con el paisaje que sufrió dos reutilizaciones diacrónicas.
Global research profile on monkeypox-related literature (1962–2022): A bibliometric analysis
Authors: Sofyantoro Fajar , Kusuma Hendrix I. , Vento Sandro , Rademaker Marius , Frediansyah Andri
Published: December 2022

The recent monkeypox or mpox outbreak has been a global concern. The present study evaluated the global research outputs, research trends, and topics of published research on monkeypox using a bibliometric approach. The Scopus database was searched for terms associated with "monkeypox" or "monkey pox" up until 19 November 2022. Maps and bibliometric indicators of the retrieved documents were shown and analyzed. A total of 1,422 documents were obtained from Scopus. Other than monkeypox, the most commonly used terms included epidemic, disease outbreaks, smallpox vaccine, and orthopoxvirus. In total, 90.3% of the documents were published between 2002 and 2022. The United States, the United Kingdom, and India were the top three countries in terms of productivity. Most of the institutions were from the United States. The International Journal of Surgery, the Journal of Medical Virology, and the Travel Medicine and Infectious Disease are some of the top journals currently publishing research on monkeypox. Tecovirimat, coronavirus disease 2019 (COVID-19), homosexuality, and pandemic are emerging topics related to monkeypox.
Infection transmission in the built environment – the interface of biology, fluid dynamics, design and human behaviour
Authors: Noakes Cath
Published: December 2022

COVID-19 has presented us with the most difficult healthcare and societal challenge we have faced in living memory. To understand the mechanisms of transmission we have had to rapidly collect new evidence on the SARS-CoV-2 virus ranging from laboratory data on survival and fluid dynamics studies on droplet dispersion through to epidemiological evidence from outbreaks, contract tracing and cohort studies. Over this time we have become acutely aware of the role that the environment plays in transmission, and how our interactions in indoor spaces determine the risk of infection. But this is not the first disease to be associated with the built environment. Many other respiratory diseases have a clear association with indoor spaces including tuberculosis and influenza. Pathogens such as pseudomonas, legionella are associated with water systems, and even hospital acquired infections such as MRSA have been linked to dispersion within the environment. This presentation sets out what we know about transmission of pathogens in the built environment particular focus on the complex interactions between engineering systems, fluid dynamics, microbiology and the behaviour of people that determine the dispersion, transport and survival of pathogens. Engineering and modelling approaches that can be used to understand mechanisms for transmission and implement mitigation strategies are discussed. The talk discusses how research findings may be used to support practice, and where there gaps in knowledge in both understanding of fundamental processes and the real performance of engineering solutions.
Time-dependent accretion discs around Kerr black holes and tidal disruption events
Authors: Balbus Steven
Published: December 2022

The theory of Newtonian astrophysical accretion discs, both in its steady and time-dependent form, dates from the mid-1970s. Relativistic thin disc theory was developed at nearly the same time, but only for steady-state conditions. I will present recent work on the fluid dynamics of time-dependent accretion discs around Kerr black holes. This work has a natural application to so-called tidal disruption events (TDEs), the tidal break-up of star when it passes too close to a galaxy's central black hole. The stellar debris collects into a disc, whose inner boundary corresponds to a radius at which the Rayleigh criterion for rotational stability is violated according to general relativity. This requires some care in its treatment, particularly with regard to the inner stress, since both the interpretation of astronomical observations and numerical simulations depend upon a detailed understanding of this innermost stable circular orbit. TDEs generally exhibit a slowly decreasing light curve that is not at present well-understood. It is, however, quite consistent with an extended evolutionary phase of time-dependent relativistic disc theory. The interplay between mathematics, fluid theory, and astrophysics is particularly striking for these objects.
Extreme Events in Fluid Dynamics: Mechanisms, Prediction and Mitigation
Authors: Farazmand Mohammad
Published: December 2022

A wide range of natural and engineering systems exhibit extreme events, i.e., spontaneous intermittent behavior manifested through sporadic bursts in the time series of their observables. Examples include ocean rogue waves, intermittency in turbulence, extreme weather patterns and epileptic seizure. Because of their undesirable impact on the system or the surrounding environment, the real-time prediction and mitigation of extreme events is of great interest. In this talk, I will discuss three aspects of extreme events. First, I introduce a variational method that unveils the mechanisms underpinning the formation of extreme events. Next, I show how this framework enables the data-driven, real-time prediction of extreme events. I demonstrate the application of this method with several examples, including the prediction of ocean rogue waves and the intermittent energy dissipation bursts in turbulent fluid flows. Finally, I will discuss a closed-loop adaptive control and a delay feedback control for mitigating extreme events.
Very-large scale motions in the atmospheric surface layer
Authors: Wang Guohua
Published: December 2022

Very-large scale motions (VLSMs) are typical structures in wall-bounded turbulence at high Reynolds number, which make important contributions to mass and energy transport. This talk will present the atmospheric surface layer observations carried out at the Qingtu Lake observation array (QLOA) site. Furthermore, some studies on the VLSMs in the atmospheric surface layer based on the observed data are introduced, including the morphological and dynamic characteristics of the VLSMs and its effect on the sand dust transportation. The influences of dust particles and heat flux on the VLSMs are discussed as well. It is found that the length scale of the VLSMs has Reynolds number invariance, and evidenced that the VLSMs in the atmospheric surface layer evolute with a top-down mechanism. In the sand-laden flow, the energy of the VLSMs increases, while their energy fraction decreases. The inclination angle of the VLSMs increases with the increase of dust concentration. It is revealed that the VLSMs dominates the streamwise transport of PM10 (tiny particles with size less than 10 μm), but suppress the vertical transport of PM10 near the surface. Finally, it is demonstrated that the temperature and PM10 in the atmospheric surface layer have large structural feature similar as the VLSMs, though the shape of temperature and PM10 structures are different with the VLSMs.
The curious dynamics of bubble oscillations and collapse
Authors: Supponen Outi
Published: December 2022

Bubbles oscillate under the effect of pressure fluctuations, such as those produced by sound waves. When driven into a violent collapse, they can yield strong sound emissions, high-speed jets, and extreme heating - a behaviour known as cavitation. In this lecture, we will present ongoing research efforts to reach a fundamental understanding of the intriguing dynamics of bubbles and the resulting flows, combining ultra-high-speed experiments with theory. The broad aim of this research lies in the quest for harnessing their power for a variety of engineering applications, including ultrasound diagnostics, drug delivery, sonochemistry, surface cleaning and micro-fluidics.
Machine Learning for Fluid Mechanics
Authors: Koumoutsakos Petros
Published: December 2022

Recent advances in machine learning and an ever increasing availability of data offer new perspectives (and hope) for solving long standing fluid mechanics problems. Despite early connections dating back to Kolmogorov, the link between Fluid Mechanics and Machine Learning (ML) has not been fully explored. The situation is rapidly changing with ML algorithms entering in numerous efforts for modeling, optimising, and controlling fluid flows. In this talk I will present works from our group on the interface of Fluid Mechanics and ML ranging from low order models for turbulent flows to deep reinforcement learning algorithms and Bayesian experimental design for collective swimming. I hope to demonstrate that ML has the potential to augment, and possibly even transform, current lines of fluid mechanics research.
Concluding remarks and some open problems
Authors: Moffatt Keith
Published: December 2022

This series of webinars was planned in commemoration of George Batchelor's promotion of the field of fluid mechanics in all its varied aspects and applications. In rounding off the series, I shall first comment on how much George Batchelor himself would have enjoyed the 15 brilliant presentations that we have heard. It is good to know that our subject is flourishing so vigorously with the young talent that has been so evident through these presentations. I shall use the short time available to me to discuss three questions that I touched on in my JFM Perspectives paper Some topological aspects of fluid dynamics: (i) How are corner eddies affected by increasing the Reynolds number of the remote forcing? ii) How does a sheet of air enter through the free-surface cusp in a tightly controlled situation? (iii) How can knotted or linked magnetic flux tubes most efficiently jump from one minimum-energy state to another?
Acrobatics of non-stick droplets
Authors: Quéré David
Published: December 2022

Making drops non-wetting increases dramatically their mobility, compared to the situations we are used to. We'll describe a few consequences of this statement, with a particular focus on jumping droplets: two non-stick drops can transfer their surface energy into kinetic energy when they merge, and thus can jump from their substrate. The materials achieving such a property might be antifogging, since condensing water is likely to be evacuated without external source of energy. We’ll discuss to what extent this optimistic view is science-fiction - wearing glasses at the time of covid, we realize how non-antifogging common materials are
Steering microscopic particles in viscous flows via shape and deformability
Authors: Lindner Anke
Published: December 2022

Understanding and controlling the transport of microscopic particles in viscous flows stems from the fundamental question of fluid-structure interactions but has also important implications for separation processes or bacterial contamination. Using recent microfabrication techniques, we produce a variety of microscopic particles and control precisely their shape and material properties. Investigating the transport dynamics of these particles in representative microfluidic flows we demonstrate how shape, mechanical properties or even activity govern particle trajectories. Combining our experimental findings with numerical and theoretical modeling performed by our collaborators we elucidate in detail the role of particle symmetry, chirality or deformability.

The development of capitalist relations in the last quarter of the 19th century introduced significant changes in the social structure of Eastern Armenians. The disintegration and stratification of the peasantry created favorable conditions for the formation of a new productive force - the working class. The construction of the railway, which started in the region in the 90s of the XIX century, also played a big role in it. The so-called "construction of the century" created favorable conditions for the formation of the largest and most influential group of Eastern Armenian workers. Combining the archival documents and periodical press reports of the time allows us to assume that up to 10,000 people worked on the construction of the Tiflis-Alexandrapol-Kars railway. Despite their outnumbering, the railway workers lived and worked in the most challenging social conditions. Absolute disenfranchisement, low pay, the arbitrariness of employers, lack of social guarantees, and safety rules created favorable conditions for the activation of social movements. The mass demonstrations, sometimes spontaneous, yet more often organized, began in December 1896 and continued until World War I, keeping the authorities in a constant state of tension.

Tigranov, the high humanistic pathos of the novel, the truthful disclosure of human characters, and the dramatic development of the action motivated L. Khoja-Einatov to write an opera. With its genre features and musical dramaturgy methods "Namous" is a lyrical-psychological opera closely related to the operatic traditions of Tchaikovsky and Rachmaninoff. "Namus" is a lyrical-psychological opera, closely related to the operatic traditions of Tchaikovsky and Rachmaninoff with its genre features and musical dramaturgy methods. A stranger to external effects, Khoja-Einatov strives for the dramatic and psychological justification of every element of the musical texture. The simple and expressive language of the opera is associated with Armenian folk music. Тhe composer does not resort to quoting folk music. Instead, the basis of the folk song is felt in the modal-intonational and metro-rhythmic features of the opera music, giving the latter a national flavor. Folk song forms in opera are enriched with compositional techniques adopted from European and Russian operatic classics. According to G. Tigranov, "Namous" is L. Khoja-Einatov's creative success, his best, artistically most complete, and mature work, and deserves its place in the history of Armenian musical theatre.

Published: December 2022

In the present study author examines the problem of development of University student’s socio-cultural competence. Learning foreign culture, value perception of the modern world, understanding the importance of the human personality and the place it takes in the cultural process are getting more and more urgent in the context of a new culturological model presuming the realization of human cultural perfection mechanisms. Sociocultural competences are becoming increasingly important and significant in terms of employability, career, competitive abilities. Acquired and developed throughout one’s lifetime, sociocultural competences create favourable conditions for successful survival and functioning in contemporary labour market. Effective teaching of methods of socialization is impossible without making an effort to conceptualize the key elements of culture in younger people’s consciousness: principles of choice of values, basics of creativity, language, ethnos, art. The paper aims at highlighting the importance of such disciplines in Learning History of Literature, Writing and Home Reading, which should be integrated into the course of Foreign Languages Speech Practice in order to develop students’ socio-cultural competence. The emphasis is put on the significance of fiction studies in preparing professionals having not only good linguistic skills but also realizing a wide range of cultural peculiarities of foreign countries. On the example of fictions by E.Hemingway, Ch.Dickens, S.Mougham, S. Fitzgerald, O.Henry, the approach to using historical facts in developing socio-cultural competence is revealed being supplemented with a number of pre-reading and post-reading activities suggested to students learning Englash as a second foreign language.

Para o bom desenvolvimento das árvores no meio urbano, visando à qualidade de vida da população, é fundamental a etapa de planejamento, que tem como elemento principal o diagnóstico da arborização. Assim, o objetivo deste trabalho foi realizar o diagnóstico da arborização viária do município de Araucária-PR. Para tanto, todas as árvores da área urbanizada do município foram contabilizadas a partir de recobrimento aerofotogramétrico e para a avaliação qualitativa realizou-se um inventário por amostragem estratificada com parcelas lineares de 500m, sendo coletadas as seguintes variáveis: espécie, CAP, altura total, altura de bifurcação, diâmetro de copa, condição física e sanitária, necessidade de tratamento, condição de raiz, posição em relação ao meio-fio, edificação e fiação, área livre de canteiro e distância entre árvores. Ao todo, enumerou-se 13.227 indivíduos arbóreos presentes nas calçadas e canteiros centrais de Araucária. Foram amostradas 773 árvores, de 70 espécies. A maior parte (44,24%) das árvores foi classificada como boa. A distribuição diamétrica indica que o município possui uma arborização jovem. Mais de 68% das árvores avaliadas apresentou altura da primeira bifurcação inferior a 1,80 m. Conclui-se que Araucária possui um bom patrimônio arbóreo, mas com problemas pontuais que com medidas de manejo e manutenção podem ser facilmente corrigidos.

A presença das árvores urbanas é fundamental para a resiliência das cidades, mitigando os efeitos das mudanças climáticas. No entanto, ela deve ser planejada para que se tenha um convívio harmônico com os mobiliários urbanos. Tendo em vista as recentes podas inadequadas pela concessionária de energia elétrica no bairro Cambuí (centro de Campinas/SP), o objetivo desta pesquisa foi analisar qualiquantitativamente os efeitos visuais das podas à paisagem urbana e estimar as possíveis perdas ecossistêmicas por meio da valoração monetária. No inventário em campo, identificou-se 299 árvores podadas sob um sistema de rede primária compacta e secundária isolada, o que não justifica tais tipos de podas, em se tratando deste tipo de rede. Os resultados revelaram a poda em 48 espécies, com destaque à sibipiruna (Cenostigma pluviosum (DC.) Gagnon & G.P.Lewis), mirindiba (Lafoensia glyptocarpa Koehne) e alecrim-de-campinas (Holocalyx balansae Micheli), resultando numa perda monetária estimada em R$ 126.094,32, o que representa uma tendência de depreciação ao patrimônio arbóreo local.

Objetivou-se neste trabalho investigar a diversidade florística e o estado fitossanitário das espécies vegetais presente nas praças do centro comercial de Teresina-PI. Para isso foram realizadas visitas semanais nas 12 praças do centro de Teresina durante o período de outubro de 2019 a março de 2020. Em nossa pesquisa encontramos 110 espécies distribuídas em 92 gêneros, 40 famílias e 2677 indivíduos. Dentre as praças, a que apresentou a maior diversidade foi a praça João Luís, as famílias mais representativas foram Fabaceae, Anacardiaceae, Arecaceae, Asparagaceae e Apocynaceae. As espécies que tiveram maior abundância foram C. prunifera, M. tomentosa, A. indica e M. indica, com 328, 305, 212 e 122 indivíduos, respectivamente. A maior parte da vegetação nas praças é formada por indivíduos de grande porte e 54% das espécies são de origem exótica. Em suma, se faz necessário em um futuro próximo que os representantes do poder público adotem medidas para influenciar o plantio de mais espécies nativas para que a discrepância entre espécies exóticas versus nativas seja maior, deixando tais praças com as características ecológicas presente em nosso bioma, situação que se espera que mude por meio de estudos como este.
