Ricostruire un teatro
Authors: Veneziano Giulia Anna Romana
Published: October 2021

Lo studio si concentra sulla macchina produttiva di un teatro strategicamente importante nel panorama culturale romano del Settecento, il teatro Alibert / Delle Dame, allo scopo di ricostruirne la valenza e l’attività. L’opera Artaserse di Leonardo Vinci / Pietro Metastasio, rappresentata nel Carnevale del 1730, viene utilizzata come study-case per dimostrare come veniva pianificata la programmazione musicale attraverso una gestione impresariale audace ed indipendente che permise di valorizzare i parametri artistici ideali provenienti da Napoli. La sopravvivenza di una documentazione eccezionale ci permette di offrire una ricostruzione quasi tridimensionale di quella che fu la macchina organizzativa del teatro, dalla scelta dei cast alla tempistica necessaria alla redazione dei contratti per le rappresentazioni stagionali, dalle concessioni delle attività commerciali legate agli spettacoli alla scoperta degli organici necessari alle recite: una gestione utile per attrarre ed ottenere il sostegno delle famiglie più influenti nello scacchiere politico ed economico della città.
Ex partibus totum
Authors: Nigito Alexandra
Published: October 2021

Muovendo dalle numerose giustificazioni per la copiatura di manoscritti musicali, conservate negli archivi gentilizi della Roma barocca, il contributo affronta la questione delle parti staccate. Attraverso l’esame di un corpus di ventisette manoscritti di sicura provenienza romana, relativo a drammi, cantate e oratori degli anni 1685-1733, è stato possibile osservare come questo medium abitualmente trascurato, al di là della sua prevedibile importanza ai fini della restituzione di un testo criticamente corretto e di una più accurata ricostruzione dell’evento musicale, dischiuda nuove prospettive di ricerca sul fronte della performance e dei riflessi che i nuovi orientamenti compositivi ebbero sulla nascente organizzazione orchestrale. Oltre ad integrare le nostre conoscenze riguardo alle date di esecuzione e ai nominativi dei musicisti coinvolti negli eventi spettacolari, il repertorio in esame ha infatti fornito nuove indicazioni su aspetti della prassi esecutiva, quali dinamiche e impiego di tutti e soli; sulla composizione e l’entità degli organici strumentali, con particolare riferimento a forme e modi di partecipazione di strumenti non specificati espressamente in partitura, come l’oboe o il contrabbasso; e sulla progressiva scomparsa del concertino in funzione preminente a favore di due compagini distinte ma omogenee di violini primi e secondi, significative dell’imporsi di un nuovo gusto musicale.
Arie e cantanti tra continuità e cambiamenti
Authors: Linden Huub van der
Published: October 2021

Il contributo prende spunto da due peculiarità del dramma per musica del Seicento: il continuo processo di revisione a cui erano sottoposti libretti e partiture durante la loro circolazione e il ruolo dei cantanti nel determinare sia questo processo sia la percezione, da parte del pubblico, di questo genere come concreta rappresentazione. Per valutare le opere dal punto di vista della loro rappresentazione, in luogo di focalizzare l’attenzione esclusivamente sulle modifiche apportate a testi e musiche nelle varie rappresentazioni, il presente studio si propone di analizzare, in maniera più sistematica di come è stato fatto finora, quelle modifiche testuali e musicali insieme a cambiamenti e continuità nei cast dei cantanti. A questo scopo vengono esaminate le due opere del Carnevale del 1693 al Teatro Tordinona: Il Seleuco e Il Vespasiano. Si tracciano le arie sostitutive e i cast delle varie produzioni che conducono alla rappresentazione romana, incrociando i dati della continuità e sostituzione di arie con i cantanti che le eseguivano. Così facendo, emerge una visione più dettagliata della correlazione tra la sostituzione di arie e di cantanti, nonché dei modi in cui la combinazione di questi due elementi plasmava l’esperienza di ascolto del pubblico. Il contributo si sofferma in particolare sul castrato Francesco Antonio Pistocchi, che sembra aver giocato un ruolo centrale nella stagione romana.
I ruoli femminili per Bartolomeo Montalcino in due opere romane di Alessandro Scarlatti
Authors: Nestola Barbara
Published: October 2021

Il contributo tratta la questione del cross-casting, espressione che designa la pratica di far interpretare ad attori o cantanti personaggi di sesso opposto, ed elemento distintivo dell’opera romana del Sei e Settecento, in due opere di Alessandro Scarlatti: Il Pompeo (1683) e La Statira (1690), l’una patrocinata da Lorenzo Onofrio Colonna e l’altra dal cardinale Pietro Ottoboni. Il contralto Bartolomeo Monaci, detto Montalcino, vi interpretò rispettivamente le parti di seconda e prima donna. Queste ultime sono analizzate alla luce della nozione del ruolo, inteso come convergenza tra l’insieme delle capacità dell’interprete (vocalità, eloquenza, fisionomia, capacità attoriali) e la parte che gli è destinata.

Published: October 2021

O trabalho tem por objetivo descrever a experiência dos terapeutas iniciantes que usam o referencial da Abordagem Centrada na Pessoa (ACP) sobre a relação terapêutica. Utilizou-se como referencial teórico a Ética da Alteridade Radical, proposta por Emmanuel Lévinas, por evidenciar o caráter obrigatório e vertical da relação com o Outro, a partir da qual é constituída a subjetividade, além de discussões sobre psicoterapia no campo da teoria psicológica em questão. Para a construção dos dados, utilizaram-se versões de sentido produzidas pelos terapeutas. Adotou-se o método fenomenológico empírico para análise. Apresentam-se sete formas assumidas pela alteridade no manejo de terapeutas iniciantes – Outro do encontro, Outro da experiência, Outro da simbolização, Outro da penumbra, Outro da ousadia, Outro da satisfação e Outro dos afetos. Para estudos posteriores, indica-se pensar a forma como a alteridade se manifesta em contextos que não apenas a clínica, bem como uma comparação sobre as manifestações da alteridade na prática de terapeutas iniciantes e experientes.

Published: October 2021

The emergence of powerful information technologies (IT) has changed innovation and entrepreneurship in significant ways. Research in IT for entrepreneurship is relatively new and there is a growing interest from academics for further studies on investigating this area of research. This study reviews research carried out in the domain of IT for entrepreneurship. A total of 1005 papers, published between 1980 and 2021 were used to uncover the latent topics addressed in this domain. A topic modeling (LDA) algorithm was used to automate the process of extracting the initial research topics from the data. The results show that IT for entrepreneurship studies are classified into six aspects of research: entrepreneurship initiative and innovation, strategy, business process management and operation management, entrepreneurship education, industry analysis, and business model. The results raise awareness of IT-associated entrepreneurship areas of research, provide useful insights for future research, and informs practice in this domain of study.
Openness to Innovation as a Driver of Knowledge Integration in High-Tech SMEs
Authors: David Kashosi Gad , Wu Yang , Pei Chen
Published: October 2021

This paper studies an original analytical framework to address the implementation dynamics of open innovation practices by discussing their impacts on SMEs' social capital and knowledge integration. A total of 358 High-Tech SMEs in the Democratic Republic of Congo participated in the survey. The collected data were statistically analyzed using structural equation modeling (SEM) in Smart PLS to verify the postulated hypothesis. The results reveal that open innovation practices promote knowledge integration, and social capital partially mediates open innovation and knowledge integration capability. The results further indicate that network competence moderates the practice of open innovation and social capital interactions with external knowledge sources. The theoretical implications of this study contribute to advance the discussion on the antecedent of social capital and knowledge integration in SMEs in developing countries and propose network competence as a moderator. The study also highlights the social capital nature of open innovation and reinforces the knowledge of scholars.

Published: October 2021

The tropical climate of Thailand encourages very high mosquito densities in certain areas and is ideal for dengue transmission, especially in the southern region where the province Nakhon Si Thammarat is located. It has the longest dengue fever transmission duration that is affected by some important climate predictors, such as rainfall, number of rainy days, temperature and humidity. We aimed to explore the relationship between weather variables and dengue and to analyse transmission hotspots and coldspots at the district-level. Poisson probability distribution of the generalized linear model (GLM) was used to examine the association between the monthly weather variable data and the reported number of dengue cases from January 2002 to December 2018 and geographic information system (GIS) for dengue hotspot analysis. Results showed a significant association between the environmental variables and dengue incidence when comparing the seasons. Temperature, sea-level pressure and wind speed had the highest coefficients, i.e. β=0.17, β= –0.12 and β= –0.11 (P<0.001), respectively. The risk of dengue incidence occurring during the rainy season was almost twice as high as that during monsoon. Statistically significant spatial clusters of dengue cases were observed all through the province in different years. Nabon was identified as a hotspot, while Pak Phanang was a coldspot for dengue fever incidence, explained by the fact that the former is a rubber-plantation hub, while the agricultural plains of the latter lend themselves to the practice of pisciculture combined with rice farming. This information is imminently important for planning apt sustainable control measures for dengue epidemics.
Geographic variability of post-disaster mental health: case study after the 2017 flood in Bangladesh
Authors: Mahmud Khandakar Hasan , Ahmed Raju , Tuya Jannatun Hussna
Published: October 2021

Every year Bangladesh faces enormous damages due to flooding. Facing these damages the Government adopts various recovery approaches. However, the psychological dimension of any disaster is generally overlooked in disaster management. Researchers have found that the spatial distribution of post-disaster mental health can help the authorities to apply recovery procedures where they are most needed. For this research, Posttraumatic Stress Checklist (PCL-5), Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were used to estimate posttraumatic stress, major depressive disorder and anxiety following three episodes of severe floods in 2017 that affected at least 8 million people. To better understand the spatial pattern of psychological vulnerability and reach a comprehensive scenario of post-disaster mental health, Moran’s I was applied for spatial autocorrelation and Pearson’s correlation and regression analysis for a study of the relationship between the psychological aspects. It was found that psychological vulnerability showed a spatial clustering pattern and that there was a strong positive linear relationship among psychological aspects in the study area. This research might help to adopt disaster management policies that consider the psychological dimension and spatial distribution of various psychological aspects to identify areas characterized by high vulnerability and risk so that they can be reached without delay.

Published: October 2021

Anaemia remains a severe public health problem among children in Ethiopia and targeted approaches, based on the distribution and specific risk factors for that setting are needed to efficiently target health interventions. An analysis was performed using Ethiopia Demographic and Health Survey 2016 data. Blood specimens for anaemia testing were collected from 9268 children aged 6-59 months. A child was considered as anaemic if the bloodhaemoglobin count was less than 11.0 g/dL. We applied Kulldorf’s spatial scan statistics and used SaTScanTM to identify locations and estimate cluster sizes. In addition, we ran the local indicator of spatial association and the Getis-Ord Gi* statistics to detect and locate hotspots and multilevel multivariable analysis to identify risk factors for anaemia clustering. More than half of children aged 6-59 months (57%) were found to be anaemic in Ethiopia. We found significant geospatial inequality of anaemia among children and identified clusters (hotspots) in the eastern part of Ethiopia. The odds of anaemia among children found within the identified cluster was 1.5 times higher than children found outside the cluster. Women anaemia, stunting and high fertility were associated with anaemia clustering.

Published: October 2021

Pre-hospital care is provided by emergency medical services (EMS) staff, the initial health care providers at the scene of disaster. This study aimed to describe the characteristics of EMS callers and space-time distribution of emergency requests in a large urban area. Descriptive thematic maps of EMS requests were created using an empirical Bayesian smoothing approach. Spatial, temporal and spatio-temporal clustering techniques were applied to EMS data based on Kulldorff scan statistics technique. Almost 225,000 calls were registered in the EMS dispatch centre during the study period. Approximately two-thirds of these calls were associated with an altered level of patient consciousness, and the median response time for rural and urban EMS dispatches was 12.2 and 10.1 minutes, respectively. Spatio-temporal clusters of EMS requests were mostly located in central parts of the city, particularly near the downtown area. However, high-response time clustered areas had a low overlap with these general, spatial clusters. This low convergence shows that some unknown factors, other than EMS requests, influence the high-response times. The findings of this study can help policymakers to better allocate EMS resources and implement tailored interventions to enhance EMS system in urban areas.

Published: October 2021

Context

The King-Devick (K-D) test is used to identify oculomotor impairment after concussion. However, the diagnostic accuracy of the K-D test over time has not been evaluated.

Objectives

To (1) examine the sensitivity and specificity of the K-D test at 0 to 6 hours postinjury, 24 to 48 hours postinjury, the beginning of a return-to-play (RTP) protocol (asymptomatic), unrestricted RTP, and 6 months postconcussion and (2) compare outcomes between athletes with and those without concussion across confounding factors (sex, age, sport contact level, academic year, learning disorder, attention-deficit/hyperactivity disorder, migraine history, concussion history, and test administration mode).

Design

Retrospective, cross-sectional design.

Setting

Multiple institutions in the Concussion Assessment, Research and Education Consortium.

Patients or Other Participants

A total of 320 athletes with a concussion (162 men, 158 women; age = 19.80 ± 1.41 years) were compared with 1239 total collegiate athletes without a concussion (646 men, 593 women; age = 20.31 ± 1.18 years).

Main Outcome Measure(s)

We calculated the K-D test time difference (in seconds) by subtracting the baseline from the most recent time. Receiver operator characteristic (ROC) curve and area under the curve (AUC) analyses were used to determine the diagnostic accuracy across time points. We identified cutoff scores and corresponding specificity at both the 80% and 70% sensitivity levels. We repeated ROC with AUC analyses using confounding factors.

Results

The K-D test predicted positive results at the 0- to 6-hour (AUC = 0.724, P < .001), 24- to 48-hour (AUC = 0.701, P < .001), RTP (AUC = 0.640, P < .001), and 6-month postconcussion (AUC = 0.615, P < .001) tim points but not at the asymptomatic time point (AUC = 0.513, P = .497). The 0- to 6-hour and 24- to 48-hour time points yielded 80% sensitivity cutoff scores of −2.6 and −3.2 seconds (ie, faster), respectively, but 46% and 41% specificity, respectively. The K-D test had a better AUC when administered using an iPad (AUC = 0.800, 95% CI = 0.747, 0.854) compared with the spiral-bound card system (AUC = 0.646, 95% CI = 0.600, 0.692; P < .001).

Conclusions

The diagnostic accuracy of the K-D test was greatest at 0 to 6 hours and 24 to 48 hours postconcussion but declined across subsequent postconcussion time points. The AUCs did not differentiate between groups across confounding factors. Our negative cutoff scores indicated that practice effects contributed to improved performance, requiring athletes to outperform their baseline scores.

Thrombotic events include both venous and arterial thrombosis. In this case report, we present a 68-year-old COVID-19 patient with multisystemic infarction who was admitted to the hospital by splenic infarction and later pulmonary embolism diagnosed during the stay in hospital despite anticoagulant use. It is important for emergency physicians to know that patients who had COVID-19 infection but not confirmed or not tested can visit the emergency department due to complications of COVID-19 infection such as thromboembolic events primarily.
Clinical significance of soluble form of poliovirus receptor in newly diagnosed follicular lymphoma
Authors: Nabih Nermeen A. , Kamal Amany M. , Naguib Mary G.
Published: October 2021

Background

Follicular lymphoma (FL) remains an incurable malignancy with heterogeneous clinical outcomes that necessitate a better understanding of disease biology. Poliovirus receptor (PVR/CD155) is markedly overexpressed in several human malignant tumors and it has a unique dual oncoimmunoregulatory role. However, the role of the soluble form of PVR (sCD155) in FL has not been fully elucidated.

Methods

Soluble PVR(sCD155) were measured in the sera of 50 patients newly diagnosed with FL by sandwich enzyme-linked immunosorbent assay and compared with those of 20 healthy control participants. Moreover, we evaluated its association with the clinicopathological parameters as well as response to chemotherapy in such patients.

Results

Pretreatment level of sCD155 was significantly higher in patients with FL than in control participants (P<0.001). Higher levels of sCD155 were associated with aggressive high-risk clinicopathological parameters, sCD155 levels were significantly higher in FL patients with B symptoms, advanced Ann Arbor stage III and IV, bulky disease, and high-risk cytogenetic (P-value=0.01, 0.048, 0.028 and <0.001, respectively). In addition, of the 50 patients, 24 (48%) achieved CR after 4–6 courses of chemotherapy (R-CHOP), while 26 (52%) were not in remission, and higher levels of sCD155 were associated with poor response to chemotherapy (P-value<0.001). Receiver operating characteristic curve was applied. Serum level of sCD155 higher than 4.8 ng/ml is a good predictor for poor response to chemotherapy (area under the curve: 0.857, sensitivity and specificity 88.46% and 75%, respectively).

Conclusion

PVR (CD155) is a potential therapeutic target that warrants further investigations and serum sCD155 may be used as a biomarker of treatment response and for predicting poor outcome in FL.
Alloimmunization in Egyptian children with sickle cell disease
Authors: Elalfy Mohsen S. , Kenny Mahmoud A. , Saed Fatima Z.A. , Ebeid Fatma S.E.
Published: October 2021

Background

Although transfusion is a cornerstone in the treatment of sickle cell disease (SCD), the subsequent erythrocyte alloimmunization creates a significant challenge in their management.

Aim

The aim was to measure the frequency of the occurrence of the alloimmune markers in SCD and to investigate its predicators.

Patients and methods

This cross-sectional study recruited 50 children and young adults with SCD. All patients were subjected to detailed medical history and thorough clinical examination. Laboratory investigations included complete blood count, markers of hemolysis, and serum ferritin. The D, C, c, E, e, M, NJKa, and JKb antigens were typed using monoclonal antisera. Fya, Fyb, Jka, Jkb, S, s, and anti-Lua antigens were typed by commercially prepared polyclonal antihuman sera. Antibody screening was performed using ortho screening panel.

Results

Sickle SS was the most common type of SCD, representing more than half of the recruited patients. The frequency of antibody positive screening among SCD was 16%. Higher frequency of alloimmunization was recorded in those with SB+ than those SS and SB0. Patients with SCD who had alloimmunization were significantly older when they received their first blood transfusion and had lower transfusion index (P=0.037) than those with negative antibodies screening (P=0.013). There were no significant differences between patients with alloimmunization and those without regarding age, sex, transfusion frequency, and SCD comorbidities; painful crisis (P=0.117), stroke (P=0.398), acute chest syndrome (ACS) (P=0.363).

Conclusion

Alloimmunization in patients with SCD has important clinical significance, especially those who require regular blood transfusion. Consequently early recognition and management of alloimunization is necessary.
Cognitive dysfunction in first-episode schizophrenia and its correlation with negative symptoms and insight
Authors: Bhat Pookala Shivaram , Raj Jitin , Chatterjee Kaushik , Srivastava Kalpana
Published: October 2021

Background:

Cognitive dysfunction in schizophrenia is a well-known feature and can adversely affect the patient participation in treatment and rehabilitation. Studies have shown its relationship to the severity of negative symptoms and level of insight also. Not many Indian studies are available on this in first-episode schizophrenia, and hence, this study was undertaken.

Materials and Methods:

Eight-five cases of first-episode schizophrenia fulfilling inclusion criteria were included in the study after ethical clearance, informed consent, and stabilization of acute symptoms. All were assessed using psychosocial pro forma, Addenbrooke's Cognitive Examination-III Scale, positive and negative syndrome scale, and schedule for the assessment of insight. Data analysis was done using Statistical Package for Social Sciences Version 20:0.

Results:

Cognitive dysfunction was seen in 40% of patients. Maximum dysfunction was in the memory domain followed by fluency domain and language domain was relatively well preserved. A significant negative correlation was observed between cognitive function and negative symptoms, but a significant positive correlation was seen with insight.

Conclusion:

Cognitive dysfunction is present in a significant proportion of schizophrenia in the first episode itself. Early assessment will facilitate appropriate interventions directed at insight and cognitive rehabilitation.

Authors: Bose Prasenjit , Choudhary Umesh , Singh Pooja , Singh Barkha , Singh Royana
Published: October 2021

Introduction:

During pulmonary vein isolation ablation procedure, the knowledge of number and position of pulmonary veins with thickness of posterior wall of left atrium (LA) is of invaluable significance. The objective of the study was to determine the left atrial wall thickness (LAWT) and its relationship with number and variations of right pulmonary veins (RPVs) and left pulmonary veins (LPVs).

Methodology:

In an observational study, carried out in the Department of Anatomy, All India Institute of Medical Sciences, Raipur (Chhattisgarh), morphological variations of pulmonary veins among 75 formalin-fixed hearts were noted. The thickness of posterior wall of LA was measured in each specimen studied. The number of RPVs and LPVs was counted. Any sexual differences in these numbers were noted.

Results:

Normal anatomical description of two RPVs and two LPVs opening the LA was observed in 63 out of 75 heart specimens (84%). The posterior LAWT is ranged 1.28–1.48 mm where two RPVs and two LPVs enter LA. The remaining 12 specimens (16%) showed variation in the number of veins opening into LA ranging between 1 and 5 veins of either side. The posterior LAWT ranged between 1.01 and 2.53 mm in these 12 specimens. The mean posterior LAWT thickness with 3, 4, and 5 RPVs was 1.47, 1.94, and 2.43 mm, respectively.

Conclusion:

The thickness of posterior wall of LA increases as the number of RPVs increases. Twelve specimens (16%) showed variation in the number of veins opening into LA ranging between 1 and 5 veins of either side.

Authors: Nair Bindu T. , Negi Vandana , Prakash Abhishek
Published: October 2021

Background:

Interns who would be the future doctors are not being observed for communication skills at their workplace. The Mini-clinical evaluation exercise (mini-CEX) can be used as a “Work Place Based Assessment” (WPBA) tool for the assessment of the communication skills of the interns and also for giving immediate feedback. This study was done to evaluate the acceptability, feasibility, and effectiveness of mini-CEX for improving the communication skills of interns in Pediatrics.

Materials and Methods:

It was a prospective interventional study which was conducted in the Department of Pediatrics. Forty interns and six faculty who volunteered participated in the mini-CEX encounters. The structured assessment mini-CEX form by the American Board of Internal Medicine was used. Each intern faced six assessment sessions on mini-CEX forms with each of the faculty. At the end of the internship rotation, the perceptions of the interns and faculty were gathered by an anonymous validated questionnaire containing both close-ended (using 5-point Likert scale) and open-ended questions.

Statistical Analysis Used:

The descriptive data were analyzed on the Statistical Package for the Social Sciences (SPSS) version 23. also done. Qualitative data of open-ended questions were done by thematic analysis.

Results:

Most interns (87.5%) and all faculty (100%) felt that mini-CEX helped them in achieving good communication skills. Comparison between the 1st and the 6th encounter of mini-CEX showed an increase in the mean score values for all skill competencies, and this improvement was statistically significant (P < 0.001).

Conclusions:

Mini-CEX is an acceptable, feasible, and effective WPBA tool for communication skills training of interns in pediatrics.
Sedimentology and ichnology of the mid-Cretaceous succession of Ouled Nail Mounts (Eastern Saharan Atlas, Algeria)

Shallow marine deposits characterize the upper Albian – lower Cenomanian deposits of Northern Algeria. In Djebel Azzeddine (Ouled Nail Mounts), the corresponding sediments have been subdivided into three distinctive units A to C. The first discovered ammonite fauna from the Bou Saada area allowed the attribution of a part of the mid-Cretaceous post-Continental Intercalaire deposits to the upper Albian. The ammonite-bearing level indicates a maximum flooding surface and could be correlated with similar levels from Northern Algeria. The studied succession is characterized by a low ichnodiversity containing eight ichnotaxa with abundant Thalassinoides, common Skolithos, and rare Gyrolithes, Oichnus, Planolites and cf. Tisoa. This ichnoassemblage is dominated by domichnion, fodinichnion and praedichnion trace fossils, and is attributed to the Skolithos and Glossifungites ichnofacies. These traces are produced mainly by decapod crustaceans, polychaetes and naticid gastropods. The sedimentological and ichnological data suggest shoreface to backshore environments with mixed tide/storm energy, and long subaerial exposures indicated by Lofer cyclothems in the lowermost part and dinosaur footprints in the upper part of the section.
Mineral assemblage and provenance of the Pliocene Viviparus beds from the Area of Vukomeričke Gorice (Central Croatia)

Published: October 2021

Viviparus beds are sediments deposited in lacustrine and fluvial freshwater environments (Lake Slavonia) during the Pliocene and the earliest Pleistocene. A detailed field study and mineralogical, petrographic and chemical analyses were carried out to determine their composition and origin in the area of Vukomeričke Gorice, Central Croatia. Viviparus beds are characterized by the vertical and lateral exchange of mineralogically and chemically mature pelites and sands. Pelitic sediments consist mainly of detrital quartz, calcite, dolomite and feldspar grains, with smectite as the most common clay mineral. Quartz and the most resistant lithic fragments dominate the sandy detritus. The composition of the sediments indicates their origin from the recycled orogen, while their textural immaturity suggests a short transport distance. Most of the material was re-deposited from the underlying Upper Miocene sediments, originally of Alpine provenance. A lesser proportion originated from Palaeogene sediments, Triassic carbonate rocks, basic or acidic magmatic rocks and metamorphites. The Medvednica and Žumberak Mts. were the most important source areas, while a smaller proportion of the material could have come from the Moslavačka gora Mt. and Banovina region. The uniform composition of the Viviparus beds over the entire vertical distribution of the sediments clearly indicates that the source areas did not change during their deposition. A significant change from the texturally and compositionally mature Upper Miocene clastic detritus of alpine origin, to the texturally immature material of the Viviparus beds of local origin is a consequence of compression and inversion of the previously extensional basin resulting in the uplifting and erosion of the mountains within the SW part of the Pannonian Basin System.
Unsettled Aspects of Insourcing and Outsourcing Additive Manufacturing
Authors:   The Barnes Global Advisors, Slattery Kevin
Published: October 2021

Additive manufacturing (AM), also known as “3D printing,” has transitioned from concepts and prototypes to part-for-part substitution—and now to the creation of part geometries that can only be made using AM. As a wide range of mobility OEMs begin to introduce AM parts into their products, the question between insourcing and outsourcing the manufacturing of AM parts has surfaced. Just like parts made using other technologies, AM parts can require significant post-processing operations. Therefore, as AM supply chains begin to develop, the sourcing of AM part building and their post-processing becomes an unsettled and important issue. Unsettled Aspects of Insourcing and Outsourcing Additive Manufacturing discusses the approaches and trade-offs of the different sourcing options for production hardware for multiple scenarios, including both metallic and polymer technologies and components.

Published: October 2021

Poor access and use of accurate, timely and appropriate climate information consistently to inform decision making in African countries pose a huge dilemma for sustainable development. The existing climate data observations networks coverage are sparsely distributed. Development strategies and plans are not adequately informed by climate science due to the limited reliable and useable climate data and information produced by National Meteorological and Hydrological Services and other relevant institutions. This paper describes the climate information needs of Cameroon, Kenya, Malawi, Nigeria and Tunisia, the status of the climate information systems (CISs), gaps and recommends improvement in the generation, processing and use of climate information. A study involving in-depth desk studies, key informant interviews, focus group discussions and policy dialogue was conducted. Results revealed that the CISs in the target countries have weak forecasting and alert systems for weather events and low capacities of stakeholders in climate prediction, development of climate products and information to support long-term planning, climate adaptation and resilience. The quality and appropriateness of data collected needs to be improved through networking, development and use of innovative technologies and capacity building. Institutionalizing climate data management training within climate data collection stations, creating modern real-time CISs by strengthening the capacities of national and regional institutions to use and disseminate climate information, is paramount. The capacity of the ministries involved in climate data management to deploy appropriate climate information and best practices to effectively implement climate-proof policies and practices should be enhanced to increase climate resilience and productivity.

Nigeria has one of the highest population growth rates in the world resulting to rapid urbanization and an enormous increase in the population leaving rural areas and now living in urban centres. In spite of the increased emphasis on rural development, rural-urban migration has persisted mainly due to the farmerherder conflict situation, poverty, lack of job opportunities, insecurity and gross inadequacy of social infrastructures in the rural areas. This mass migration and other factors have put Nigeria in an emergency food and nutrition insecure situation. Before the COVID-19 pandemic, there was already an existing gap in the Nigerian food system, which led to the importation of food items to augment local production in order to meet local demand. However, the emergence of the COVID-19 pandemic undermined efforts to achieve SDG 2 as the country witnessed not only a major disruption to food supply chains in the wake of lockdowns and movement restrictions triggered by the global health crisis, but also a major economic slowdown. The commerce, service, and agricultural sectors were the hardest hit by the spread of the virus and the effects are different along the rural-urban continuum. The vacuum created by the migration of people from the rural to urban areas led to reduction of farm yields, while the urban areas were particularly affected in terms of food supply from rural areas as a result of movement restrictions made during the height of the pandemic. More urbanised areas may be harder hit than remote rural areas if connectivity remains broken down, as most food crops are produced in the rural and semi-rural areas. This paper recommends strategies and policies aimed at reducing poverty, food insecurity and inequality across the urban-rural continuum through agricultural development. This will assist in addressing the adverse drivers of migration with particular focus on improving the social and economic conditions of rural areas.

The role of soil in saving human race from COVID-19 pandemic
Authors: Asadu C.L.A.
Published: October 2021

Soil is the most complex part of land as its contents are made of all the other key components of land namely geology (soil minerals), hydrology (soil water), atmosphere (soil air), and organisms including man (soil organic matter including dead bodies). This is why the functions of the soil are not only numerous but also indispensable. Among the functions, the role of the soil in sustaining human life remains unimaginable. Over 3.8 million people have been killed by COVID-19 by June 15, 2021 in the world and more are still dying. Some unrecorded millions died of hunger as a result of the lockdown during the peak of COVID-19 pandemic. Where are these dead bodies and materials associated with those that died of COVID-19? Where did all the food palliatives (rice, maize, wheat, yam, gari, vegetable oil, etc.) come from? The human body is composed of approximately 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. When decomposed these various components result to various gaseous compounds and residues that are harmful to human life and environment. When dead bodies are buried human health and environment are saved. The dead bodies, the wastes and their contents are in the soil providing “palliatives” to soil microorganisms while protecting the remaining human population and the environment. Cremation products also end up in the soil. The soil also provided and still provides the food palliatives. Thus, the soil is our number one saviour against COVID-19 pandemic and can be adjudged as the saviour of the human race to date. Coincidentally man was made from the soil and must return to the soil.

Prospects for the adoption of Agile Project Management techniques in Nigerian construction industry
Authors: Esangbedo O.P. , Ealefoh D.E.
Published: October 2021

Persistent failure of construction projects to meet clients’ objectives has compelled a review of the extant systems for project delivery. This study assessed the prospect of adopting Agile Project Management (APM) for construction project delivery in Lagos State. To achieve this, the study examined the level of awareness of APM among construction stakeholders and developed a SWOT model for the adoption of APM technique for construction projects. The research adopted survey method using questionnaire. The study sample involved 196 construction stakeholders. Data obtained were analysed using Mean Score and Fussy Set Theory. The result showed that stakeholders’ level of awareness about the individual methodologies of APM is high. There are also weighty strengths, weaknesses, opportunities and threats in the adoption of APM in construction project delivery. The level of awareness among stakeholders portrays high prospects for APM adoption. However, there is need to embed trust, cooperation and improved team performance.
Development of a modified environment for oyster mushroom (Pleurotus ostreatus) production system for rural use in Southeast Nigeria
Authors: Ogbu B.U. , Okonkwo W.I. , Ugwu S.N.
Published: October 2021

This study investigated a Pleurotus ostreatus production in Nsukka, Nigeria, using the locally available materials. A modified controlled environmental system capable of maintaining the micro elements (temperature and relative humidity) suitable for cultivation of oyster mushroom was developed. The system was tested using substrates of biomaterial origin (saw dust and rice bran) at different levels of treatments. The substrates used were fermented sawdust supplemented with rice bran at a spawning level of 0%, 5%, 10%, 15%, and 20%. The steps involved in the cultivation were composting, bagging, spawning, incubation and cropping the substrates. The experiment was laid out in a completely randomized design in five replications and results analysed at P < 0.05 significant difference. The biological efficiency was determined to establish the minimum suitable nutrient supplementation levels and the best yield of Pleurotus ostreatus. The nutritional compositions of the yield were analysed. The highest mean yield of 24.5 g of fresh mushrooms was observed with the substrate mixture T3 (15% rice bran and 85% saw dust) and lowest yield of 8.6 g observed in the T0 (without rice bran). The effects of temperature and relative humidity on growth of oyster mushroom were evaluated. The result of this study showed that small-scale, indoor oyster mushroom production appears to be economically feasible in Nsukka.
Taxation of Digital Companies: Experience of Russia and Other Countries

It is generally recognized that local self-government is the most effective way to meet the basic socio-economic needs of the population. It is local self-government that takes on those public law functions that, by their very nature, cannot be realized by the forces of the state.
The existing mechanisms of interaction between the state and local self-government are built on the basis of the principle of subsidiarity, aimed at supporting local budgets by the state, but they cannot always ensure sufficient and timely replenishment of local budgets.
So, for example, we are left to conclude that local government is unable to influence such parameters as the collection and distribution of taxes. Although tax revenues are partially distributed in favor of local government, municipalities are often forced to look for sources of additional funding, which can be carried out at the expense of the population.
The article aims to analyze the existing mechanisms for mobilizing funds from the population by municipalities in the world in general and in Russia in particular.
The Origins and Evolution of Deposit Banking Activities – Analysis of the Literature
Authors: Mikliński Maciej
Published: October 2021

The current norms governing deposit banking activities are the result of a centuries-old evolution of the construct of bank account, the legal nature of bank account, the subject of deposit, and banking institutions themselves. Different civilizations and cultures have contributed to the shaping of deposit activities. The aim of the article is to present and discuss, from a historical-legal point of view, the origin and unfolding of deposit banking activities over time: from antiquity, through the Middle Ages, the early modern period, to modern times. The deliberations are set against a broader financial and legal backdrop to include the transformation of economic power that accompanies deposit activities, expressed in the form of: commodity money, bullion, paper money, and funds. The picture of evolution is completed by the emerging institutions of supervision, capital requirements or deposit guarantee schemes, constituting a series of normative solutions adopted due to the need to provide a framework for deposit activities that would prioritize the security of the depositor. The study, due to its historical-legal character within the scope of detailed sciences, does not aim at applying the conclusions in legal practice or in the theoretical-legal dimension. It serves to collect and show the already acquired historical-legal knowledge about the foundations of contemporary normative solutions of bank deposit activities. In order to achieve the research goal, the study uses the research method of critical literature review. Thus, a reference was made to scientific historical-legal and historical studies, from the point of view of a selected research problem, which has not been elaborated in a cross-sectional manner so far.
Social media and COVID-19: A global study of digital crisis interaction among Gen Z and millennials
Authors:   University of Melbourne, Volkmer Ingrid
Published: October 2021

The COVID-19 pandemic is revealing that global big tech platforms and social media are core sites for continuous engagement with crisis content for young citizens. This study included twenty-four countries from all continents at the time of the heightened COVID-19 crisis, and our survey targeted 18-40 year olds, Millennials and Gen Zs – overall n = 23,483 respondents. Outcomes show that for young citizens across continents, crisis communication is not just about press briefings. Instead, crisis communication is continuous interaction and engagement across their multiple source environments. Young citizens navigate social media, national media, search sites and messaging apps, they engage with peer communities, science and health experts and – across all countries – substantially with the social media content of the World Health Organization (WHO). Overall, they create their own individual crisis narrative based on the sources they use and the insights they select. This report outlines these new crisis communication dimensions within a transnational social media space and offers numerous suggestions for incorporating social media in crisis response strategies.

Mental stress is showing harmfulness to human health leads abnormal stress in chronology with this may lose our mental health for proactive care. With recognizable pieces of proof of web-based media, individuals cannot share their everyday exercises and collaborate with companions via web-based media stages, making it happing to use online informal community information for stress identification. We find that users stress state is closely associated with thereupon of his/her friends in social media, which we employ a large-scale dataset from real-world social platforms to systematically study the relationship between users’ stress states and social interactions. We first define a gaggle of stress-related comments, images, and social attributes from various aspects, then proposed a plot. Research results saying that the proposed model can improve the detection performance. With the help of enumeration, we build an internet site for the users to spot their stress rate level and may check other related activities.
