Website Quality, Brand Image, Brand Trust, Repurchase Intentions, and Customer Satisfaction
Authors: Sari Ni Komang Meita , Darma Gede Sri
Published: October 2023

This study investigates the relationship between website quality, brand image, brand trust, customer satisfaction, and repurchase intentions. This study specifically looks at the function of customer satisfaction as an influencing factor. The data collection technique in this study was a questionnaire using the Google Form platform which was distributed directly to all Goldmine Coffee Sunrise consumers using a QR Code. Based on a sample of 150 respondents, the results of the direct influence study show that website quality and brand image affect repurchase intentions. On the other hand, direct influence research shows that brand trust and customer satisfaction have no effect on repurchase intentions, and indirect effects show website quality, brand image, and brand trust do not affect repurchase intentions through customer satisfaction. This research supports the theory of consumer behavior and contributes to the marketing management literature by recognizing that website quality and brand image are important in consumer purchasing decisions. This research also contributes to providing a different view of brand trust and customer satisfaction which shows that consumer trust and satisfaction do not always generate an intention to make a repeat purchase.

Business competition in this globalization and digital era is very tight. General Managers & Human Resources Leaders face their own challenges. To work around this, qualified and highly qualified Human Resources are needed to be able to give the best contribution to the company, especially to respond to competition that arises in the business, especially related to the availability of talented employees. This study aims to obtain information about the implementation of Talent Management that has been carried out by star hotels in Bali. This research is exploratory research with a qualitative approach. The total number of respondents was 16 people consisting of 3 people from Prime Plaza Hotel & Suites Sanur-Bali, 4 people from Capella Ubud, 3 people from Swan Paradise a Pramana Experience, 3 people from Four Seasons Resort Bali, and 3 people from Mercure. Bali Legion. Where the selection of respondents represents a variety of hotel management, including hotels managed internationally (international chained hotels) and nationally (national chained hotels), 4 and 5 star categories. The application of Talent Management in hotels has a significant impact on producing competent and qualified Human Resources to support the increase in the company's competitiveness against its competitors. Another positive result is that the level of loyalty from employees to the company also increases. As was the case with the Capella Ubud Hotel, where their employees decided to resign because of a promotion, a better offer to cruise ship management, or abroad. The results obtained are that Talent Management is very important to do, because this system is effective and efficient in increasing employee competence, which will then increase the company's competitiveness against its competitors. Likewise with the Four Seasons Resort Bali, after the pandemic, many young people joined, and they joined the Four Seasons to see opportunities abroad. There have been quite a lot of employee transfers to overseas branches.

The Inhomogeneity Effect. II. Rotational and Orbital States Impact Planetary Cooling
Authors: Zhang Xi
Published: October 2023

We generalize the theory of the inhomogeneity effect to enable comparison among different inhomogeneous planets. A metric of inhomogeneity based on the cumulative distribution function is applied to investigate the dependence of planetary cooling on previously overlooked parameters. The mean surface temperature of airless planets increases with rotational rate and surface thermal inertia, which bounds the value in the tidally locked configuration and the equilibrium temperature. Using an analytical model, we demonstrate that the internal heat flux of giant planets exhibits significant spatial variability, primarily emitted from the nightside and high-latitude regions acting as radiator fins. Given a horizontally uniform interior temperature in the convective zone, the outgoing internal flux increases up to several folds as the inhomogeneity of the incoming stellar flux increases. The enhancement decreases with increasing heat redistribution through planetary dynamics or rotation. The outgoing internal flux on rapidly rotating planets generally increases with planetary obliquity and orbital eccentricity. The radiative timescale and true anomaly of the vernal equinox also play significant roles. If the radiative timescale is long, the outgoing internal flux shows a slightly decreasing but nonlinear trend with obliquity. Our findings indicate that rotational and orbital states greatly influence the cooling of planets and impact the interior evolution of giant planets, particularly for tidally locked planets and planets with high eccentricity and obliquity (such as Uranus), as well as the spatial and temporal variations of their cooling fluxes.
The Inhomogeneity Effect. I. Inhomogeneous Surface and Atmosphere Accelerate Planetary Cooling
Authors: Zhang Xi
Published: October 2023

We propose a general principle that under radiative-convective equilibrium, the spatial and temporal variations in a planet’s surface and atmosphere tend to increase its cooling. This principle is based on Jensen’s inequality and the curvature of the response functions of surface temperature and outgoing cooling flux to changes in incoming stellar flux and atmospheric opacity. We use an analytical model to demonstrate that this principle holds for various planet types: (1) on an airless planet, the mean surface temperature is lower than its equilibrium temperature; (2) on terrestrial planets with atmospheres, the inhomogeneity of incoming stellar flux and atmospheric opacity reduces the mean surface temperature; (3) on giant planets, inhomogeneously distributed stellar flux and atmospheric opacity increase the outgoing infrared flux, cooling the interior. Although the inhomogeneity of visible opacity might sometimes heat the atmosphere, the effect is generally much smaller than the inhomogeneous cooling effect of infrared opacity. Compared with the homogeneous case, the mean surface temperature on inhomogeneous terrestrial planets can decrease by more than 20%, and the internal heat flux on giant planets can increase by over an order of magnitude. Despite simplifications in our analytical framework, the effect of stellar flux inhomogeneity appears to be robust, while further research is needed to fully understand the effects of opacity inhomogeneity in more realistic situations. This principle impacts our understanding of planetary habitability and the evolution of giant planets using low-resolution and one-dimensional frameworks that may have previously overlooked the role of inhomogeneity.

Published: October 2023

In situ measurements from spacecraft typically provide a time series at a single location through coronal mass ejections (CMEs), and they have been one of the main methods to investigate CMEs. The CME properties derived from these in situ measurements are affected by temporal changes that occur as the CME passes over the spacecraft, such as radial expansion and aging, as well as spatial variations within a CME. This study uses multispacecraft measurements of the same CME at close separations to investigate both the spatial variability (how different a CME profile is when probed by two spacecraft close to each other) and the so-called aging effect (the effect of the time evolution on in situ properties). We compile a database of 19 events from the past 4 decades measured by two spacecraft with a radial separation of <0.2 au and an angular separation of <10°. We find that the average magnetic field strength measured by the two spacecraft differs by 18% of the typical average value, which highlights nonnegligible spatial or temporal variations. For one particular event, measurements taken by the two spacecraft allow us to quantify and significantly reduce the aging effect to estimate the asymmetry of the magnetic field strength profile. This study reveals that single-spacecraft time series near 1 au can be strongly affected by aging and that correcting for self-similar expansion does not capture the whole aging effect.
Galactic Diffuse γ-Ray Emission from GeV to PeV Energies in Light of Up-to-date Cosmic-Ray Measurements
Authors: Zhang Rui , Huang Xiaoyuan , Xu Zhi-Hui , Zhao Shiping , Yuan Qiang
Published: October 2023

Diffuse γ-ray emission between 10 and 1000 TeV from the Galactic plane was recently measured by the Large High Altitude Air Shower Observatory (LHAASO). These observations will help tremendously in constraining the propagation and interaction of cosmic rays in the Milky Way. Additionally, new measurements of cosmic-ray spectra reach a very high precision of up to 100 TeV energies, revealing multiple spectral structures of various species. In this work, based on up-to-date measurements of local cosmic-ray spectra and a simplified propagation setup, we confront a model prediction of diffuse γ-ray emission with measurements of diffuse γ-rays. To better constrain the low-energy part of the model, we analyze the 14.6 yr of Fermi Large Area Telescope (Fermi-LAT) data to extract the Galactic diffuse emission between 1 and 500 GeV from the same sky regions of LHAASO, after subtracting the contribution from known sources and the isotropic diffuse γ-ray background. The joint Fermi-LAT and LHAASO spectra thus cover a very wide energy range from 1 GeV to 1 PeV with small gaps from 0.5 to 10 TeV. Compared with the prediction, we find that clear excesses between several GeV and ∼60 TeV of the diffuse emission exist. Possible reasons to explain the excesses may include unresolved sources or more complicated propagation models. We illustrate that an exponential cutoff power-law component with an index of −2.40 and a cutoff energy of ∼30 TeV is able to account for such excesses.

Moreover, the two pairs were on the opposite side of the X-line as they observed the bidirectional accelerated electron jets. The fortuitous formation of MMS allows us to estimate the maximum length of the inner EDR as ∼36 d

and the lower bound of the reconnection rate as 0.142 ± 0.041. These observations have far-reaching implications for understanding the electron physics in reconnection.
Decomposing the Origin of TeV–PeV Emission from the Galactic Plane: Implications of Multimessenger Observations
Authors: Fang Ke , Murase Kohta
Published: October 2023

High-energy neutrino and γ-ray emission has been observed from the Galactic plane, which may come from individual sources and/or diffuse cosmic rays. We evaluate the contribution of these two components through the multimessenger connection between neutrinos and γ-rays in hadronic interactions. We derive maximum fluxes of neutrino emission from the Galactic plane using γ-ray catalogs, including 4FGL, HGPS, 3HWC, and 1LHAASO, and measurements of the Galactic diffuse emission by Tibet ASγ and LHAASO. We find that the IceCube Galactic neutrino flux is larger than the contribution from all resolved sources when excluding promising leptonic sources such as pulsars, pulsar wind nebulae, and TeV halos. Our result indicates that the Galactic neutrino emission is likely dominated by the diffuse emission by the cosmic-ray sea and unresolved hadronic γ-ray sources. In addition, the IceCube flux is comparable to the sum of the flux of nonpulsar sources and the LHAASO diffuse emission especially above ∼30 TeV. This implies that the LHAASO diffuse emission may dominantly originate from hadronic interactions, either as the truly diffuse emission or unresolved hadronic emitters. Future observations of neutrino telescopes and air-shower γ-ray experiments in the Southern hemisphere are needed to accurately disentangle the source and diffuse emission of the Milky Way.

Pavo was identified in Dark Energy Camera Legacy Survey imaging via a novel approach that combines low surface brightness galaxy search algorithms and machine-learning candidate classifications. Follow-up imaging with the Inamori-Magellan Areal Camera and Spectrograph on the 6.5 m Magellan Baade telescope revealed a color–magnitude diagram (CMD) with an old stellar population, in addition to the young population that dominates the integrated light, and a tip of the red giant branch distance estimate of

However, Pavo appears to be even more isolated, with no other known galaxy residing within over 600 kpc. As surveys and search techniques continue to improve, we anticipate an entire population of analogous objects being detected just outside the Local Group.

Deep observations with the James Webb Space Telescope (JWST) have revealed an emerging population of red pointlike sources that could provide a link between the postulated supermassive black hole seeds and observed quasars. In this work, we present a JWST/NIRSpec spectrum from the JWST Cycle 1 UNCOVER Treasury survey of a massive accreting black hole at z = 8.50 displaying a clear broad-line component as inferred from the Hβ line with FWHM = 3439 ± 413 km s−1, typical of the broad-line region of an active galactic nucleus (AGN). The AGN nature of this object is further supported by high ionization, as inferred from emission lines, and a point-source morphology. We compute a black hole mass of

This is orders of magnitude higher compared to the local QSOs but consistent with recent AGN studies at high redshift with JWST. This finding suggests that a nonnegligible fraction of supermassive black holes either started out from massive seeds and/or grew at a super-Eddington rate at high redshift. Given the predicted number densities of high-z faint AGN, future NIRSpec observations of larger samples will allow us to further investigate galaxy–black hole coevolution in the early Universe.

On the construction of recurrent fractal interpolation functions using Geraghty contractions
Authors: Attia Najmeddine , Jebali Hajer
Published: October 2023

The recurrent iterated function systems (RIFS) were first introduced by Barnsley and Demko and generalized the usual iterated function systems (IFS). This new method allowed the construction of more general sets, which do not have to exhibit the strict self similarity of the IFS case and, in particular, the construction of recurrent fractal interpolation functions (RFIF). Given a data set $ \{ (x_n, y_n) \in I\times \mathbb R, n = 0, 1, \ldots, N \} $ where $ I = [x_0, x_N] $, we ensured that attractors of RIFS constructed using Geraghty contractions were graphs of some continuous functions which interpolated the given data. Our approach goes beyond the classical framework and provided a wide variety of systems for different approximations problems and, thus, gives more flexibility and applicability of the fractal interpolation method. As an application, we studied the error rates of time series related to the vaccination of COVID-19 using RFIF, and we compared them with the obtained results on the FIF.

Based on the well-posedness of model, the family of pullback attractors for the evolutionary processes generated by a global weak solution has been obtained, which is unique and minimal, via verifying asymptotic compactness in functional space with delay $ C_V $ and topological space $ V\times C_V $, where the energy equation method and a retarded Gronwall inequality are utilized.
Conformable finite element method for conformable fractional partial differential equations
Authors: Sadek Lakhlifa , Lazǎr Tania A , Hashim Ishak
Published: October 2023

The finite element (FE) method is a widely used numerical technique for approximating solutions to various problems in different fields such as thermal diffusion, mechanics of continuous media, electromagnetism and multi-physics problems. Recently, there has been growing interest among researchers in the application of fractional derivatives. In this paper, we present a generalization of the FE method known as the conformable finite element method, which is specifically designed to solve conformable fractional partial differential equations (CF-PDE). We introduce the basis functions that are used to approximate the solution of CF-PDE and provide error estimation techniques. Furthermore, we provide an illustrative example to demonstrate the effectiveness of the proposed method. This work serves as a starting point for tackling more complex problems involving fractional derivatives.
Population dynamics model for aging
Authors: Demongeot Jacques , Magal Pierre
Published: October 2023

The chronological age used in demography describes the linear evolution of the life of a living being. The chronological age cannot give precise information about the exact developmental stage or aging processes an organism has reached. On the contrary, the biological age (or epigenetic age) represents the true evolution of the tissues and organs of the living being. Biological age is not always linear and sometimes proceeds by discontinuous jumps. These jumps can be negative (we then speak of rejuvenation) or positive (in the event of premature aging), and they can be dependent on endogenous events such as pregnancy (negative jump) or stroke (positive jump) or exogenous ones such as surgical treatment (negative jump) or infectious disease (positive jump). The article proposes a mathematical model of the biological age by defining a valid model for the two types of jumps (positive and negative). The existence and uniqueness of the solution are solved, and its temporal dynamic is analyzed using a moments equation. We also provide some individual-based stochastic simulations.

Este trabajo aporta herramientas de análisis para la comprensión de los cambios ambientales ocurridos en el sector occidental de la provincia de San Luis (Argentina) entre el periodo del Pleistoceno tardío y el Holoceno medio (ca. 12.600 a ca. 3.600 años AP), utilizando la información provista por diatomeas, como indicadores paleobiológicos. Se analizó la mitad inferior del testigo SBIII (10 a 5 m) obtenido en la cuenca endorreica salino-lacustre Salina del Bebedero (33° 20′ S; 66° 45′ O; 380 (m s.n.m.).
Los picos de mayor abundancia relativa de la especie planctónica Cyclotella choctawhatcheeana sugieren episodios de gran aporte de agua a la laguna, procedente de la Cordillera de los Andes a través del río Desaguadero.
Estos episodios estuvieron intercalados por periodos con bajos niveles lacustres (ambientes someros o palustres) caracterizados por la presencia de diatomeas epifíticas y bentónicas y se identificaron intervalos donde no se encontraron diatomeas.
También discutimos y articulamos la información paleoambiental inferida para el período comprendido entre ca. 12.600 y 3.600 años AP, a partir de los registros de diatomeas, con la información disponible de otros proxies (polen y sedimentología), con el fin de mejorar el modelo paleoambiental generado previamente para la región.
Este trabajo amplía el conocimiento de ensambles de diatomeas en sistemas lacustres hipersalinos de los Andes orientales durante el periodo estudiado, revelando la importancia de algunos taxones como indicadores de condiciones más húmedas durante el inicio del Holoceno y en etapas más recientes dentro de este periodo y, además, este estudio, profundiza los conocimientos existentes sobre la biodiversidad diatomológica en esta provincia.
Sindemia de obesidade e COVID-19: uma sobreposição pandémica e o reforço das desigualdades de saúde
Authors: Roriz Marta
Published: October 2023

A obesidade surgiu como forte fator de risco para os quadros graves de infeção por COVID-19, tornando os indivíduos com obesidade mais suscetíveis à hospitalização, ventilação assistida e morte. O presente artigo reflete como obesidade e COVID-19 compõem uma sobreposição de pandemias de efeitos sindémicos, cujas sinergias reforçam quer desvantagens biológicas quer estruturais, reproduzindo e agravando disparidades e desigualdades de saúde persistentes ao longo do tempo. O caso da obesidade e a sua ecologia de problemas de saúde constitui um desafio de saúde global, que aponta a necessidade de olhar a saúde num quadro mais alargado que tenha em conta como os motores centrais da sociedade e a política económica e social sob o neoliberalismo afetam a distribuição da saúde e doença, condicionando potencialmente outras crises virais pandémicas no futuro.
O vilipêndio da COVID-19 em call e contact centres em Portugal
Authors: Roque Isabel
Published: October 2023

Desde o final da década de 1990 que os call e contact centres em Portugal têm vindo a enfrentar questões não apenas relacionadas com direitos laborais, mas também com a segurança e saúde no trabalho. Com a eclosão da pandemia de COVID-19, estes locais tornaram-se focos de contágio do vírus. As desigualdades de classe foram agravadas pela demarcação entre trabalhadores essenciais e não essenciais. Após o decretar do estado de emergência, a maioria dos operadores de call e contact centre transitou para o regime de teletrabalho, sofrendo uma importante perda de direitos laborais e um aumento do controlo e da vigilância pervasiva, bem como dos riscos psicossociais. Entre março de 2020 e maio de 2022, recorrendo a uma pesquisa netnográfica, foram realizadas entrevistas em profundidade com operadores e sindicalistas de call e contact centre em Portugal para analisar os impactos da pandemia e a transição para o teletrabalho.

Published: October 2023

Digitalization in education is crucial because it transforms conventional learning strategies and offers new options for both students and teachers. This research aims to look into how transformational headteachers are practicing digitalization in primary schools in Bangladesh. This study follows a mixed method that includes both qualitative and quantitative approaches. At first transformational leadership self-assessment scale, which McShane et al. developed based on the research of Podsakoff et al., was used to measure transformational head teachers. Then 16 head teachers, 16 teachers, and 16 FGDs were conducted to get in-depth views. This study indicates that primary school head teachers who demonstrate transformational leadership have the vision to digitalize their schools because they are conscious of the digitalization impact, but due to financial barriers, resource shortage, and infrastructural constraints, lack of skills among them and class teachers, head teachers cannot practice digitalization in their school, which is the barrier for ensuring quality education.

Published: October 2023

The chapter presents the results of a survey of students from a Russian regional university, conducted at the request of its administration in order to study students' satisfaction with the conditions and quality of education they receive, to clarify the attitude of students to the opportunities provided by the university and their activities outside the educational process at the university. The survey involved 1,636 people, which was about 35% of the total number of full-time students. According to the results of the study, it was found that students are mainly satisfied with the conditions and quality of training, arrangement, and opportunities of the educational environment of the university, relations with teachers and classmates. Furthermore, they positively assess the developmental effect of the education received. In contrast, about 12% of respondents said they were dissatisfied with the quality of education. The analysis shows that dissatisfaction with the learning conditions and the quality of education correlates with the low self-organization of this group of students.

The review also outlines some of the literature that had touched on this topic, as well as the respective findings from such studies and the conclusions reached on the impact of a lack of ICTs at rural schools.
How a Song can be Exhibited in a Music Museum
Authors: Zhi Lin
Published: October 2023

This paper will focus on the folksongs of people living in Napo, Nanning, and Funin in Guangxi Autonomous Region and Yunnan province. The study was initiated with the experience of working at the new Music Museum of the city of Nanning established within the campus of Guangxi Arts University. Since this is a Music Museum, arrangements were made to exhibit a sample repertoire of folksongs from this region in addition to all the interesting musical instruments. This was a very difficult task as it is a well observable fact that a song does not exist in a single version as it moves from one place to another, and changes all the time. This paper is about the experiences during this particular activity and how these difficulties had to be mastered. There might be others who face the same difficulties. As such, this paper may help find solution for the problems encountered by other music museums. Technically, this is the elaboration about a topic strongly connected to live interviews and personally collected statistics that were found through an intense personal presence in the mentioned area. The reference style had to be adapted to these circumstances. In order to make information traceable, many parts of the references carry translations in square brackets behind the transliteration. Also, Chinese names are left as a whole despite starting with the family name, the middle name and given names are tremendously important for identification. Name characters are presented in square brackets. Material can be obtained upon request made per email to the author.

In the subject areas of performing and visual arts, most teaching and learning take place in the traditional classroom, with face-to-face instruction methods but as a result of the COVID-19 pandemic the University of Visual and Performing Arts (UVPA) promptly moved the delivery of all of its undergraduate courses to an online format. During the COVID-19 period, the UVPA, like other Sri Lankan universities, began to use emerging technologies and tools such as Zoom and a Learning Management System (LMS) for pedagogical intent. The goal of this study is to find out what teaching strategies can be applied to improve music teaching and learning in an online environment and how faculty staff experienced teaching music online. This research is designed as a Multiple Case Study. Depending on the purpose of the research, structured interviews were conducted to collect feedback from randomly selected faculty members. The participants were eight faculty members from the Faculty of Music engaged in teaching during the 2018/2019 academic year. Previously, the Faculty of Music has underutilized e-learning and the use of an LMS. However, the recent COVID-19 outbreak has forced them to rely on e-learning/online learning in order to ensure the continuity of educating the students enrolled in the degree programmes offered by the faculty. The results revealed that most of the teaching staff were new to teaching music online; however, they learned how to teach online given the circumstances which had left them with no other feasible solution. According to this study, the online music teaching activities utilized have improved teaching performance and technological skills and abilities, saved time, allowed participants to complete tasks more quickly, enhanced productivity of work, and increased educational values.
Study on the Importance of Including Concepts Related to Value Education in the Grade Six Western Music Sri Lankan School Curriculum
Authors: Kumara G.S.G. Wasantha
Published: October 2023

A perfect person is not born at birth. Just as we learn mathematics and languages, we should also become specialists in those lessons that are fundamental to living in harmony and social progress, such as respect, empathy, equality, solidarity, and critical thinking. Without these and other ethical principles that define us as human beings, it will be difficult for us to build a better world.

Value education, therefore, promotes tolerance and understanding above and beyond our political, cultural, and religious differences, putting special emphasis on the defense of human rights, the protection of ethnic minorities and the most vulnerable groups, and the conservation of the environment. Developing value education in students is the primary responsibility of all stakeholders, and it is not the sole responsibility of each school. It is the collective responsibility of the family, schools, universities, businesses, and sports associations to provide all the ideal contexts to teach those ethical principles.

Teachers and students are directly involved in the learning-teaching process of the school system according to the curriculum designed for the school system by the Education Ministry of Sri Lanka. Teachers must have a good understanding of the syllabi relevant to any subject and have a good understanding of school children. Teachers should comprehend their learners’ needs, tastes emotions, possibilities, aspirations, and mental and psychological capacities. Therefore, teachers are the major contributors among the key parties who make any changes and developments in the curriculum. Teachers have a vast body of knowledge and experience about the knowledge, skills, and attitudes to be taught to children through the curriculum, as well as concepts and skills related to good personal and social habits, and it is important to look into that when the curriculum is reformed.

All these malpractices occurred because of the lack of knowledge of religious, moral and education values. Therefore, it is the foremost duty of each and every citizen of Sri Lanka to promote and rebuild value education. As such, this study may help to promote and develop a specific value education in the school system of Sri Lanka.

If students do not learn good values through education, they will have to face various problems not only in school but also in society. The incorporation of value concepts into the school curriculum may be a solution to resolve this situation. When designing curricular, one needs to ask such questions such as, how should value concepts be included in the curriculum? What are the values that should be taught in the current curriculum? Failure to ask teachers about the inclusion of value concepts into the school curriculum can lead to several practical problems in the learning-teaching process.
The Position of Kabir Bhajans in North Indian Music
Authors: Abeysekara G.G.G.L.
Published: October 2023

Kabirdas is a poet who lived in medieval India. He visioned to spread social purity with philosophical thinking through the poems which are termed as Nirgun bhajans. Bhajan is simply known for chanting the qualities and the physical appearance of Hindu deity/deities. The bhajans or poems composed by Kabirdas are not consisting of the latter, but they are also put under the term 'bhajan' in terms of lyrics and their musical presentation. Traditionally, bhajans refer to devotional songs that depict the qualities and physical attributes of various deities. However, Kabirdas' bhajans deviate from this norm by focusing on different themes, while maintaining a certain essence of traditional bhajans. This study investigates how the melodies of Kabir bhajans effects in the absence of chanting the qualities and the physical appearance of a Hindu deity/deities in the lyrics. This study also aims to look at the broader significance of devotional music in promoting social and philosophical ideals in medieval India.
Issues in Radio Music Broadcasting in the Sri Lankan Cultural Environment
Authors: Alawathukotuwa Manoj
Published: October 2023

The interference of mass media plays a key role in changing people's listening behavior and thinking patterns in numerous ways. Due to technological factors, a majority of Sri Lankans are exposed to “light songs” which are music tracks to last only for three to five minutes. From earlier to present times, almost all recording and reproducing technologies in the island have been used basically for this purpose. Various types of government and private FM channels, TV channels, and social media propagate these forms of songs in the contemporary music scene for different purposes. Because of the commercial benefits and good demand for songs, mobile network companies also promote artists to record songs according to the contemporary taste of the younger generation. This study discusses how Sri Lankan music was stuck to a monocentric stream of light songs due to the fact that the listeners in Sri Lanka are constantly being exposed to “light songs” through radio broadcasting and radio politics.

A 59-year-old patient without a history of pulmonary disease presented with episodes of hemoptysis and acute respiratory failure after receiving fulvestrant and palbociclib for metastatic breast cancer. The High-Resolution chest CT demonstrated diffuse ground glass opacities, as well as diffuse smooth thickening of the interlobular septa and peribronchovascular interstitium, which are consistent with Drug-Induced Interstitial Lung Disease (DIILD). A few days of high-dose steroid therapy improved the patient's gas exchange from PaO2/FiO2 of 75 to 200. After hospital discharge, the oncologist resumed fulvestrant therapy, with no additional adverse events occurring during the subsequent follow-up.

Inflammatory Myofibroblastic Tumor (IMT) is an exceptionally uncommon benign tumor. We present a 54-year-old man with IMT, frequent episodes of respiratory infections, aspergillosis, and hemoptysis, who has received 23 years of conservative treatment. A successful left intrapericardial pneumonectomy was performed. During chest closure, the left atrial auricle lesion caused a massive hemorrhage owing to contact with the staplers of the left pulmonary artery stapler line. The bleeding was immediately controlled. One year after surgery, the patient has fully recovered and no adverse events or relapses have occurred.

Primula ×chignolensis (Ericales: Primulaceae), a new primrose hybrid discovered in Val Seriana (northern Italy)
Authors: Banfi Enrico , Ferlinghetti Renato
Published: October 2023

A new hybrid of primrose discovered fifteen years ago in the locality Bivacco La Plana, Pre-Alps of Bergamo, above Chignolo, a hamlet of the municipality of Oneta, later also confirmed for the crest of Mount Alben, always in the same municipality, is here described. The parental species turn out to be Primula albenensis Banfi & Ferl. and P. auricula L., the former endemic to the mountains of Bergamo (Mount Alben, Mount Aralalta group and the Ancogno Valley), the latter a European orophyte, here coexisting often together on limestone faces. The new finding shows constant morphology in its stands, and there is no evidence of either "hybrid swarming" or introgression to exclude the total sterility of the population and this occurrence should be considered result of a process of inter parentes hybrid speciation (nothospecies) deserving of taxonomic recognition.
