A Robust Predictive Model for Stock Price Prediction Using Deep Learning and Natural Language Processing
Authors: Sen Jaydip , Mehtab Sidra
Published: July 2021

Prediction of future movement of stock prices has been a subject matter of many research work. There is a gamut of literature of technical analysis of stock prices where the objective is to identify patterns in stock price movements and derive profit from it. Improving the prediction accuracy remains the single most challenge in this area of research. We propose a hybrid approach for stock price movement prediction using machine learning, deep learning, and natural language processing. We select the NIFTY 50 index values of the National Stock Exchange (NSE) of India, and collect its daily price movement over a period of three years (2015 – 2017). Based on the data of 2015 – 2017, we build various predictive models using machine learning, and then use those models to predict the closing value of NIFTY 50 for the period January 2018 till June 2019 with a prediction horizon of one week. For predicting the price movement patterns, we use a number of classification techniques, while for predicting the actual closing price of the stock, various regression models have been used. We also build a Long and Short-Term Memory (LSTM)-based deep learning network for predicting the closing price of the stocks and compare the prediction accuracies of the machine learning models with the LSTM model. We further augment the predictive model by integrating a sentiment analysis module on Twitter data to correlate the public sentiment of stock prices with the market sentiment. This has been done using Twitter sentiment and previous week closing values to predict stock price movement for the next week. We tested our proposed scheme using a cross validation method based on Self Organizing Fuzzy Neural Networks (SOFNN) and found extremely interesting results.
Set Partitioning in Hierarchical Trees for Point Cloud Attribute Compression
Authors: de Queiroz Ricardo , Souto Andre , Figueiredo Victor , Chou Philip
Published: July 2021

We propose an embedded attribute encoding method for point clouds based on set partitioning in hierarchical trees (SPIHT) [1]. The encoder is used with the region-adaptive hierarchical transform [2] which has been a popular transform for point cloud coding, even included in the standard geometry-based point cloud coder (G-PCC) [3],[4]. The result is an encoder that is efficient, scalable, and embedded. That is, higher compression is achieved by trimming the full bit-stream. G-PCC’s RAHT coefficient prediction prevents the straightforward incorporation of SPIHT into G-PCC. However, our results over other RAHT based coders are promising, improving over the original, nonpredictive RAHT encoder, while providing the key functionality of being embedded.
TEST BENCH SOLAR POWER MEASUREMENT
Authors: Swarupa Lakshmi
Published: July 2021

Nowadays, Solar power is
utilized more in domestic, commercial, and industrial applications.
Solar energy is renewable energy which is produced from sun heat. In 2020 India
solar installed capacity was 34,627 MW. In this paper developed an experimental
setup for solar panel power measurement. In this current, voltage and light
intensity has been measured. Declination angle of sun to earth is
+23.5°degrees, -23.5°degrees. The model of sun is represented by an
incandescent bulb light and the angles set up manually. In this
explained about solar power output at load side and see the variation between
power and load resistance. Solar panel is generated power by light intensity
applied by using incandescent light bulb. The light intensity changed by using
a voltage regulator. The power is measured by using voltmeter and ammeter
readings. Solar energy is to emulate the solar panel output power
characteristics. The model of sun was taken as an incandescent bulb light and
placed on the circular iron track to change east to the west. By changing the
position of the bulb and changing the bulb light intensity with the help of the
D.C speed regulator. Solar panel is placed in such a way that it freely moves
to certain angles. By taking voltmeter and ammeter readings calculate the
power. The graph is drawn between resistance versus power, the unique source of
energy. The main aim of the paper is. Ensure that the maximum power output
occurs at load which is taken as a resistor bank.
Análise da Dinâmica Temporal da Paisagem do Município Amazônico de São Geraldo do Araguaia-PA, Brasil
Authors: Silva Samuel Santos , Mendes Maurício Ferreira , Perlandim Ramos Alexander Webber
Published: July 2021

Este trabalho tem como objetivo analisar a dinâmica da paisagem e mensurar a pressão antrópica sobre os componentes ambientais do município de São Geraldo do Araguaia – Pará. Foram utilizados dados de mapeamentos de cobertura vegetal e usos da terra do projeto MapBiomas (1988-2018). A mensuração da pressão antrópica foi realizada por meio da aplicação do Índice de Transformação Antrópica (ITA) com o intuito de verificar a paisagem em sua totalidade e de forma isolada, considerando as áreas que possuem proteção ambiental. No período analisado, ocorreram diversas modificações na paisagem natural no município. O resultado do ITA evidenciou que essas modificações têm gerado pressão sobre os componentes da paisagem e, consequentemente, uma piora no estado de conservação ambiental da municipalidade. Pode-se verificar que as áreas com proteção ambiental, apesar de apresentarem antropização, foram de suma importância para conter o desmatamento, amenizando a pressão sobre os componentes naturais.

Objective: To evaluate the performance of lung ultrasound to determine short-term outcomes of patients with COVID-19 admitted to the intensive care unit. Methods: This is a Prospective, observational study. Between July and November 2020, 59 patients were included and underwent at least two LUS assessments using LUS score (range 0-42) on day of admission, day 5th, and 10th of admission. Results: Age was 66.5±15 years, APACHE II was 8.3±3.9, 12 (20%) patients had malignancy, 46 (78%) patients had a non-invasive ventilation/high-flow nasal cannula and 38 (64%) patients required mechanical ventilation. The median stay in ICU was 12 days (IQR 8.5-20.5 days). ICU or hospital mortality was 54%. On admission, the LUS score was 20.8±6.1; on day 5th and day 10th of admission, scores were 27.6±5.5 and 29.4±5.3, respectively (P=0.007). As clinical condition deteriorated the LUS score increased, with a positive correlation of 0.52, P <0.001. Patients with worse LUS on day 5th versus better score had a mortality of 76% versus 33% (OR 6.29, 95%CI 2.01-19.65, p. 0.003); a similar difference was observed on day 10. LUS score of 5th day of admission had an area under the curve of 0.80, best cut-point of 27, sensitivity and specificity of 0.75 and 0.78 respectively. Conclusion: These findings position LUS as a simple and reproducible method to predict the course of COVID-19 patients.

A socio-technical intervention in BIM projects – an experimental study in global virtual teams
Authors: Anderson Anne , Ramalingam Shobha
Published: July 2021

‘Global Projects’ and ‘Global Virtual Teams’ are revolutionizing the construction industry. An increasing number of multi-national engineering firms are adopting this business model due to the possible advantages of cost and time optimization. However, literature identifies several challenges that the project teams endure in temporarily organizing while transitioning through time and space, some of which include cross-cultural differences in teams and limited richness of the communication media. Perceiving virtual project execution as a multi-variable construct, organizational theorists and sociologists adopt a socio-technical approach to understand the dynamics of action embedded in the process and recommend implementation of pre-process, during process or post process intervention strategies to enable performance. In this paper, we address this research concern through an experimental study conducted across two global universities, National Institute of Construction Management and Research, Pune, India and Washington State University, USA. Around 24 students from each university in ten teams collaborated virtually for a period of 2.5 weeks to develop a 3-dimensional Revit model and a 4-dimensional BIM model in Autodesk Revit and Navisworks, respectively, for a multi-storey residential building. The study aimed to investigate the role of project teams in organizing and coordinating projects tasks and taking a socio-technical approach, explored the role of a BIM Execution Plan as a pre-process intervention strategy. Data collected through qualitative survey post the experiment was qualitatively analyzed using ethnographic coding techniques. Findings showed that the project and team challenges primarily stemmed from coordination issues and institutional differences. Members significantly mitigated the issues through a proactive approach and a priori planning. The BIM Execution Plan allowed members to instantly get involved with the tasks and plan the process apart from being able to foresee the complexity. Teams emphasized the importance of implementing a detailed BIM Execution Plan during the planning phase for a collaborative and successful project outcome and further observed that pre-process intervention strategy such as a BIM plan was the needed impetus for members to collaborate and coordinate project tasks.

Authors: Karmakar Ankan , Delhi Venkata Santosh Kumar
Published: July 2021

The last decade has witnessed unprecedented changes in the technologies and processes involved in the construction industry. The philosophies associated with Industry 4.0 now reverberate in construction 4.0. Digitalization and interconnectivity in the cyber-physical systems of the sector are at the heart of such transformation. Construction 4.0 brings to the table a plethora of technologies and associated processes over the construction project lifecycle. The current study performs a state-of-art literature review to summarize the knowledge advancement in construction 4.0. A layered conceptualization spanning across project lifecycle utilizing the people-process-technology dimensions is presented to summarize the current understanding of Construction 4.0. The cyber-physical space is classified into the physical, digital tool, data, and core data security and interoperability layers. The inter-layer and intra-layer interactions and information flows are then conceptualized based on the extant literature, including the human interaction and interventions. The people-process-technology dimensions were discussed across the project lifecycle through interactions in these layers. It is observed that Construction 4.0 is set to be driven by data creation, data flow, data transformation, and data storage across the project lifecycle to ensure a collaborative environment across the stakeholders who interact and associate with different layers of Construction 4.0. The article finally presents challenges with the current formulations and explores ways to further our knowledge in the area.

#WEDOSRPP avagy a szociálisan felelős közbeszerzések
Authors: Fáskerty Éva
Published: July 2021

Az SRPP alkalmazásával a gyakorlatban az ajánlatkérőknek több nehézsége is akad, tekintettel arra, hogy a nettó ajánlati ár értékelési szempontja mellett a fenntarthatóság jegyében a szociális és környezetvédelmi szempontoknak minél nagyobb teret kíván engedni mind a Közbeszerzési Hatóság és a Miniszterelnökség, mind a támogató szervezetek. Előfordul azonban, hogy az ajánlatkérők nem minden esetben tudják értékelni sem a szociális, sem a környezetvédelmi és innovatív szempontokat. Mindezek mellett a horizontális klauzula megjelenésével a közbeszerzési eljárások egészében az ajánlatkérőknek következetesen meg kell tenniük a szükséges lépéseket annak érdekében, hogy teljesüljenek mindazok a környezetvédelmi, szociális és munkajogi kötelezettségek, amelyek a nemzeti, az uniós, illetve a nemzetközi jog alapján irányadóak. A környezetvédelmi szempontok fokozottabb beépülése miatt az ajánlatkérő szervek számára lehetővé kell tenni, hogy a közbeszerzési szerződés tárgyát képező építési beruházásokkal, árukkal vagy szolgáltatásokkal kapcsolatban a termék bármely életciklusához kapcsolódóan meghatározzanak odaítélési szempontokat. A környezetvédelmi értékelési szempontokat illetően a vállalás típusú szempontok során konkrét mérhetőséget is meg kell követelni, mivel ennek hiányában nem jelent előnyt, illetve az előny nem határozható meg adekvát módon a gazdaságilag legelőnyösebb ajánlat kiválasztása körében. Az új Kbt.-vel összhangban Magyarországon több gyakorlati példát is láthatunk a hirdetményekben a fenntarthatósági kritériumok meghatározására így például a megvalósuló épület energia felhasználása vonatkozásában, a kivitelezés során alkalmazott gépek CO2 kibocsátása vonatkozásában, a teljesítés során a bontott anyagok újra-felhasználásának aránya szerint vagy például a környezetterhelési érték (összesített CO2 érték), a napelemtábla hatásfokára vagy a napelemtábla évenkénti teljesítményvesztésére vonatkozó paraméterek szerint. Értekezésemben az irányadó szabályozás hátterét, okait és a lehetséges irányokat tekintem át.

Home gardens are an essential component of the local food system and family farming worldwide. In Indonesia, a home food gardening program was initiated in the early 2010s to optimally utilize home yards for improving the adequacy of food consumption and nutrition intake of households. In the present challenging situation of Covid-19 pandemic, there has been a growing interest in home gardens to help mitigate food insecurity caused by food supply chain disruptions and the emergence of physical and economic barriers that limit access to food. This paper is a review of pertinent literature to find out the characteristics of home gardens and home gardening program in Indonesia and then examine their contribution to each pillar of food security: availability, access, utilization, and stability. The experiences of home gardens worldwide are reviewed to understand the global context of home gardens and food security. Literature reviews found a positive impact of home gardening program on food availability, access, and utilization. However, improving food stability through a home food gardening program is still a challenging task. This finding implies that the positive contribution of the home food gardening program to household food security is largely limited to the program period. Nevertheless, the program is still an important strategy to address food insecurity and nutrition deficiency of low-income households. Future research should assess factors affecting the sustainability of the program to derive viable models applicable in diverse circumstances. There is a need for research to assess the value and importance of home gardens as a coping strategy to reduce vulnerability and food insecurity in the present global Covid-19 pandemic.

Dark Times: Art and Artists of Vilnius in 1939–1941
Authors: Jankevičiūtė Giedrė
Published: July 2021

The aim of this paper is to discuss and reconstruct in general features the reality of the Vilnius artistic community from late autumn 1939 to June 1941. This period of less than two years significantly changed the configuration of the artistic community of the city, the system of institutions shaping the art scene as well as the artistic goals. It also brought forth new names and inspired new images. These changes were above all determined by political circumstances: the war that broke out in Poland on 1 September 1939; the ceding of Vilnius and the Vilnius region to Lithuania; two Soviet occupations: in the autumn of 1939 and June 1940, and the subsequent Nazi occupation a year later. The influence of politics on the art scene and the life of artists has been explored in institutional and other aspects by both Lithuanian and Polish art historians, but the big picture is not yet complete, and the general narrative is still under construction. A further aim of this paper is to highlight some elements that have not received sufficient attention in historiography and that are necessary for the reconstruction of the whole. Some facts of cooperation or its absence among artists of various ethnicities are presented, and the question is raised on the extent to which these different groups were affected by Sovietisation, and what impact this fragmentation had on the city’s art scene. The timeline of the activity of the higher art school and the Art Museum has been detailed.

Questioning the Efficacy of Reading Storybooks to Very Young Japanese EFL Learners: A Vocabulary Study
Authors: Winn Luke
Published: July 2021

This study is concerned with vocabulary acquisition from reading ‘authentic’ English storybooks to very young Japanese children in an immersion EFL setting. 26 children took part in a quasi-experimental study which examined two reading techniques. A multiple readings condition offered three verbatim readings of three different storybooks (nine readings in total), whereas the second condition added brief L2 explanations of target words within a single reading of each book (three readings in total). Prior vocabulary in L2 (English) was also measured to evaluate its effect on word learning. A post-treatment target word vocabulary test was conducted to assess for acquisition. The results of the study show that neither reading condition resulted in significant effects with regard to word learning. The effect of prior vocabulary (both L1 and L2), however, was significant, and implications for educators working with children in this age group are discussed.

Intolerance of uncertainty is associated with heightened responding in the prefrontal cortex during cue-signalled uncertainty of threat
Authors: Morriss Jayne , Bell Tiffany , Biagi Nicolò , Johnstone Tom , van Reekum Carien M.
Published: July 2021

Heightened responding to uncertain threat is considered a hallmark of anxiety disorder pathology. We sought to determine whether individual differences in self-reported intolerance of uncertainty (IU), a key transdiagnostic dimension in anxiety-related pathology, underlies differential recruitment of neural circuitry during cue-signalled uncertainty of threat (n = 42). In an instructed threat of shock task, cues signalled uncertain threat of shock (50%) or certain safety from shock. Ratings of arousal and valence, skin conductance response (SCR), and functional magnetic resonance imaging were acquired. Overall, participants displayed greater ratings of arousal and negative valence, SCR, and amygdala activation to uncertain threat versus safe cues. IU was not associated with greater arousal ratings, SCR, or amygdala activation to uncertain threat versus safe cues. However, we found that high IU was associated with greater ratings of negative valence and greater activity in the medial prefrontal cortex and dorsomedial rostral prefrontal cortex to uncertain threat versus safe cues. These findings suggest that during cue-signalled uncertainty of threat, individuals high in IU rate uncertain threat as aversive and engage prefrontal cortical regions known to be involved in safety-signalling and conscious threat appraisal. Taken together, these findings highlight the potential of IU in modulating safety-signalling and conscious appraisal mechanisms in situations with cue-signalled uncertainty of threat, which may be relevant to models of anxiety-related pathology.
ANALYSIS OF THE INFLUENCE OF MULTINATIONAL, AUDIT QUALITY AND COMPANY SIZE ON THIN CAPITALIZATION OF MANUFACTURING COMPANIES LISTED ON THE IDX
Authors: Whidyawhati Vonny , Sari Dian Purnama
Published: July 2021

Tax avoidance can be carried out through some schemes, one of them is through thin capitalization. Thin capitalization is a tax avoidance practice carried out by companies through financing their business from high debt instead of capital. In Indonesia, thin capitalization is first regulated in KMK-1002 / KMK.04 / 1984 which later changed to PMK 169 / PMK.010 / 2015. The purpose of this study is to analyze the effect of multinational, quality audits, and company size on thin capitalization. The research object includes manufacturing companies listed on IDX within the period of 2017 - 2019. The sample obtained includes 299 companies. This study uses secondary data in the form of financial reports. The data analysis technique used in this study is multiple regression analysis. The results show that multinational have no effect on thin capitalization, audit quality has negative effect on thin capitalization and firm size has positive effect on thin capitalization.
Identification of Blood Protozoa in See-See Partridges (Ammoperdix Griseogularis) in Garmian Area/Kurdistan Region-Iraq
Authors: Wahab Mohammed , Ali Shahnaz , Abdulrahman Nawzad
Published: July 2021

Haemosporidians are intracellular protozoan parasites found inside the blood cells and tissues of avian hosts; they are almost worldwide distributed and occur in a variety of avian species, including see-see partridge birds. Blood samples were collected from 63 see-see partridges during a period extended from 19th November 2018 to 15th March of 2019 in the Garmian area/Iraqi Kurdistan region to detect and investigate the infection rates of haemosporidian parasites by microscopic examination using Giemsa stained smears. The results of the study showed that out of the total samples numbers 63 only 43 were found infected with haemoprotozoan parasites composing the overall infection rate of 68,25%, from 32 birds which were infected with Plasmodium spp. at a rate 50,79%, and 8 birds were infected with Haemoproteus spp. at a rate of 12,69%., the results also revealed that the rates of infection with these protozoan parasites vary substantially among the sampled locations. The present study showed that two haemosporidian genera (Haemoproteus spp. and Plasmodium spp.) were detected in see-see partridges in Kurdistan region-Iraq for the first time, and this type of bird is considered as a new host record for these haemoprotozoa in this area.
Cadernos Brasil na OCDE : compras públicas

Published: July 2021

Compras públicas podem ser consideradas como processos de aquisições de bens, serviços e obras por parte da administração pública ou das empresas estatais. Embora os governos possam prover bens e serviços diretamente, a racionalidade econômica sugere que, na grande parte dos casos, a melhor solução seria contratar empresas privadas para prover tais bens ou serviços, uma vez que podem fazê-lo de forma mais eficiente. O mercado de compras públicas corresponde a, aproximadamente, 12% das economias dos países- -membros da Organização para Cooperação e Desenvolvimento Econômico (OCDE), atingindo proporção semelhante no Brasil. Essas compras vão desde a aquisição de materiais de escritório para repartições públicas até a execução de grandes obras de infraestrutura como pontes e aeroportos, movimentando empresas em, virtualmente, todos os setores da economia. Devido à sua importância, os países costumam regulamentar o processo licitatório, ou seja, o procedimento administrativo de compras públicas, objetivando garantir transparência, isonomia, eficiência e celeridade. Por esse motivo, a OCDE passou a analisar práticas licitatórias dos seus países-membros, contrastando métodos e resultados com o objetivo de definir quais seriam as melhores práticas regulatórias sobre o tema. Paralelamente, o Brasil também reformou suas normas licitatórias ao longo dos anos. A criação do Regime Diferenciado de Contratações Públicas (RDC), disposto na Lei nº 12.462/2011, na Lei Anticorrupção (Lei nº 12.846/2013) e na Lei das Estatais (Lei nº 13.303/2016), é apenas um exemplo de reformas importantes instituídas no país para garantir maior agilidade e transparência ao processo. Este texto se propõe a apresentar, em linhas gerais, a perspectiva da OCDE sobre o tema e cotejá-la com alguns elementos do histórico brasileiro recente, inclusive no que diz respeito ao debate relativo ao uso do poder de compra como instrumento de realização de objetivos governamentais – correspondente ao que a OCDE denomina objetivos secundários das compras públicas.
The 3.3 μm Infrared Emission Feature: Observational and Laboratory Constraints on Its Carrier
Authors: Tokunaga Alan T. , Bernstein Lawrence S.
Published: July 2021

We examine the self-consistency of laboratory and observational data for potential carriers of the 3.3 μm infrared emission feature (IEF), a member of the ubiquitous family of strong interstellar IEFs at 3.3, 3.4, 6.2, 7.7, 8.6, 11.2, and 12.7 μm. Previous studies have shown that most Galactic sources (reflection nebulae, H ii regions, and planetary nebulae) show 3.3 μm IEFs displaying similar central wavelengths, FWHM, and profiles. Our study is focused on the band profile designated as Class A, the most prevalent of four classes of observed band profiles. In contrast to the observations, laboratory spectra for gas phase polycyclic aromatic hydrocarbons (PAHs), the widely assumed carriers of the IEFs, display central wavelength shifts, widths, and profiles that vary with temperature and PAH size. We present an extrapolation of the laboratory band shifts and widths for smaller PAHs (≤32 carbon atoms) to the larger PAHs (>50 carbon atoms) that are thought to be the IEF carriers. The extrapolation leads to tight constraints on the sizes of the putative PAH carriers. Reconciling the observations with the implications of the laboratory spectra pose a significant challenge to the PAH and other IEF carrier hypotheses.

Two extremely red main-belt asteroids, 203 Pompeja and 269 Justitia, were identified from combined visible and near-infrared spectroscopic observations collected at the Infra-red Telescope Facility (IRTF) and Seoul National University Astronomical Observatory (SAO). These two asteroids have a redder spectral slope than any other D-type body, which are the reddest objects in the asteroid belt, and similar to RR and IR-class objects found in the outer Solar System among trans-Neptunian objects (TNOs) and Centaurs. Spectroscopic results suggest the presence of complex organic materials on the surface layer of these asteroids, implying that they could have formed in the vicinity of Neptune and been transplanted to the main belt region during a phase of planetary migration. 203 Pompeja is the only very red asteroid known so far among the ∼250 bodies with diameter larger than 110 km (i.e., presumably structurally intact) found in the asteroid belt. These discoveries provide more evidence that the main asteroid belt hosts a population of bodies that were formed in the outskirts of the Solar System.

During 2020 April and May, SGR J1935+2154 emitted hundreds of short bursts and became one of the most prolific transient magnetars. At the onset of the active bursting period, a 130 s burst “forest,” which included some bursts with peculiar time profiles, were observed with the Fermi/Gamma-ray Burst Monitor (GBM). In this Letter, we present the results of time-resolved spectral analysis of this burst “forest” episode, which occurred on 2020 April 27. We identify thermal spectral components prevalent during the entire 130 s episode; high-energy maxima appear during the photon flux peaks, which are modulated by the spin period of the source. Moreover, the evolution of the ν

spectral hardness (represented by E
peak or blackbody temperature) within the lightcurve peaks is anti-correlated with the pulse phases extrapolated from the pulsation observed within the persistent soft X-ray emission of the source six hours later. Throughout the episode, the emitting area of the high-energy (hotter) component is 1–2 orders of magnitude smaller than that for the low-energy component. We interpret this with a geometrical viewing angle scenario, inferring that the high-energy component likely originates from a low-altitude hotspot located within closed toroidal magnetic field lines.

Published: July 2021

This data paper describes a new, comprehensive database (BIOVERA-Epi) on species distributions and leaf functional traits of vascular epiphytes, a poorly studied plant group, along gradients of elevation and forest-use intensity in the central part of Veracruz State, Mexico. The distribution data includes frequencies of 271 vascular epiphyte species belonging to 92 genera and 23 families across 120 20 m × 20 m forest plots at eight study sites along an elevational gradient from sea level to 3500 m a.s.l. In addition, BIOVERA-Epi provides information on 1595 measurements of nine morphological and chemical leaf traits from 474 individuals and 102 species. For morphological leaf traits, we provide data on each sampled leaf. For chemical leaf traits, we provide data at the species level per site and land-use type. We also provide complementary information for each of the sampled plots and host trees. BIOVERA-Epi contributes to an emerging body of synthetic epiphytes studies combining functional traits and community composition.

BIOVERA-Epi includes data on species frequency and leaf traits from 120 forest plots distributed along an elevational gradient including six different forest types and three levels of forest-use intensity. It will expand the breadth of studies on epiphyte diversity, conservation, and functional plant ecology in the Neotropics and will contribute to future synthetic studies on the ecology and diversity of tropical epiphyte assemblages.
Loneliness in Homebound Older Adults: Integrative Literature Review
Authors: Ezeokonkwo Francesca C. , Sekula Kathleen L. , Theeke Laurie A.
Published: July 2021

Loneliness affects people of all ages at one point or another in their lives; however, older adults aged ≥65 years are disproportionally affected due to age-related losses. Most research on loneliness has focused on older adults in general. Older adults who are homebound tend to have more disabilities and associated complications than older adults in the general population and face unique challenges. The current review examined and synthesized knowledge about loneliness among older adults who are homebound using Whittemore and Knafl's analysis process. Fourteen studies published from 1999 to 2020 met the inclusion criteria. The analysis resulted in four themes: characteristics of loneliness in older adults who are homebound, risks for homebound in older adults, location of older adults who are homebound, and coping strategies and methods to reduce loneliness in this population. Implications for nursing practice and recommendations for future research are discussed. [

Social Media and Retinal Detachment: Perspectives of Providers and Patients on Instagram
Authors: Alsoudi Amer F. , Rayess Nadim , Khan Suleman , Koo Euna , Rahimy Ehsan
Published: July 2021

BACKGROUND AND OBJECTIVE:

To evaluate the social media interactions of patients who experience retinal detachment and/or repair and how ophthalmic medical providers utilize social media.

PATIENTS AND METHODS:

A cross-sectional study of public posts on Instagram was performed from September 2019 to January 2020, with filtering based on the following hashtags: #retinaldetachment, #detachedretina, #retinaldetachmentsurgery, and #scleralbuckle. A categorical classification system was used for each Instagram post to review descriptive variables.

RESULTS:

Of the 1,797 Instagram posts analyzed, 697 (39%) were made by patients, of which 395 (57%) were positive in tone and 599 (86%) were in the postoperative period. Posts by ophthalmologists were most commonly centered on colleague education (446, 81%).

CONCLUSIONS:

The majority of Instagram posts by patients were of a positive tone reflecting primarily on activities of daily living and rehabilitations. Retina specialists should consider providing more social media content directed toward patients, particularly regarding their rehabilitation course following retinal detachment repair.

Atypical Late-Onset Exudative Retinal Detachment in a Treatment-Naïve Infant With Retinopathy of Prematurity
Authors: Schaffer Lauren R. , Hubbard G. Baker , Mukkamala Krishna , Rao Prethy
Published: July 2021

A male infant born at 23 weeks gestation with a birthweight of 660 grams presented with retinopathy of prematurity (ROP) that began progressing at 44 weeks. He subsequently developed Zone III, Stage 3, pre-plus disease in both eyes (OU), as well as scattered exudates in the macula, dragged vessels temporally, and an exudative retinal detachment temporally in the left eye after a period of regressing and stable ROP. After bilateral laser photocoagulation, there was regression of the neovascularization, resolution of the exudative detachment, and eventual stabilization of disease OU by 12 months postmenstrual age.

Ports and logistics: resilience, sustainability and new centrality in the post-pandemic perspective for Italy and EU Med ports
Authors: Palmentieri Stefania ,   Department of Humanities, University of Naples "Federico II", Italy
Published: July 2021

This article is part of the Economic Geography studies and deals with aspects related to intermodal logistics with particular reference to maritime transport of containers. Ports are historically one of the key infrastructures for the Italian economy. In recent decades, along with many industrial sectors that were once driving forces for the national economy, due to the lack of adequate strategic planning, it has failed to keep pace with the rapid changes imposed on all sectors involved in the process of globalization of the economic world, losing ground and competitiveness with respect to many competing realities, both in Northern Europe and in the Mediterranean basin itself [1]. Most of the other states of Mediterranean Europe are in similar conditions, but Italy is probably the one that has lost the most ground. In this situation of strong economic and social imbalance, the covid-19 epidemic has hit Italy before and dramatically and if it had not turned into a pandemic, hitting the rest of Europe and the planet and forcing the European institutions to launch, for the first time, concrete support measures for all, would probably have represented a fatal shock for the Italian economy. By elaborating the information on statistical data and projections available in numerous international publications on the transport economy and more specifically on logistics, taking into account the reasons for the successes and failures of similar realities to the Italian one, the study offers food for thought on what to do immediately and in the future, taking advantage of the unique and unrepeatable opportunity constituted by the economic initiatives for the post-pandemic recovery, to remedy the lost ground by returning an adequate role to our world of maritime and port transport which can also be a driving force for the territory behind, avoiding ending up on the edge of the evolved world.

Authors: Neamah Majid K. ,   Department of Mathematical Sciences, Faculty of Science and Technology, Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor, Malaysia, Ibrahim Alawiah
Published: July 2021

In this paper, we establish some inequalities for convex functions by applying the generalized proportional fractional integral. Some new results by using the linkage between the proportional fractional integral and the Riemann-Liouville fractional integral are obtained. Moreover, we give special cases of our reported results. Obtained results provide generalizations for some of the current results in the literature by applying some special values to the parameters.

In this paper, we prove two existence results of solutions for an $ \psi $-Hilfer fractional non-instantaneous impulsive differential inclusion in the presence of delay in an infinite dimensional Banah spaces. Then, by using the multivalued weakly Picard operator theory, we study the stability of solutions for the considered problem in the sense of $ \psi $-generalized Ulam-Hyers. To achieve our aim, we present a relation between any solution of the considered problem and the corresponding fractional integral equation. The given problem here is new because it contains a delay and non-instantaneous impulses effect. Examples are given to clarify the possibility of applicability our assumptions.
