Published: October 2021

This study proposes a strategy development framework for information management in a construction business. The framework covers the typical project lifecycle of a construction business which includes work winning and delivery. It incorporates a cultural analysis approach that covers the range of cultural manifestations expected in organisations. The approach also combines qualitative and quantitative research techniques. Application of the proposed framework for the development of information management strategy in a leading construction business showed that examining the information culture of the leadership and staff of the organisation is helpful in exposing the relevant informational issues. The case study also helped to validate that the proposed framework is a viable method for identifying and resolving informational issues inherent in construction organisations. Lastly, considering that the information management strategy developed in this study is for a typical construction business, other companies in the same domain will find the resource valuable.

Severe infection and its evolution to sepsis are becoming more prevalent every day and are among the leading causes of critical illness and mortality. Proper management is crucial to improve prognosis. This document addresses three essential points that have a significant impact on this objective: a) early recognition of patients with sepsis criteria, b) identification of those patients who suffer from an infection and have a high risk of progressing to sepsis, and c) adequate selection and optimization of the initial antimicrobial treatment.
“O Crime do Padre Amaro”: o drama que se descobre nas narrativas de Eça de Queiroz (1875), Carlos Coelho da Silva (2005) e Paula Rego (1997-1999)
Authors: Da Silva Santana Helena Maria , Da Silva Santana Maria do Rosário
Published: October 2021

O Crime do Padre Amaro (1874) was written by Eça de Queiroz in 1871 and given to read to some of his friends in 1872. According to Eça de Queiroz, this work was published for the first time only in 1875. As some issues of the Western Magazine, it was made without changes or corrections, and preserving all its sketchy features and improvisation (preface of the 2nd Edition). However, Eça de Queiroz decides to reconstruct it. So, he rewrites line by line all the text and, by adding new chapters to the story and modifying the action, he also changes the entire structure of the work making it the one we know today. Nowadays, this work brought up, given the plot that covers it, themes that are current and expounded in various works of cinema, literature, and visual arts. In this sense, we want to enlighten how these authors reveal the problems of ancient and contemporary society, in their visual and sound discourses. Color, sound, discursive options, and distinct interpretations will be the pillar of our investigation regarding the elucidation made by Eça de Queiroz and the technical and aesthetic options of Silva and Rego.
A reunião: um diálogo entre a arte e o design para gestão e criação de um produto audiovisual em meio a pandemia de COVID-19 Orlando José Dantas Lopes
Authors: Dantas Lopes Orlando José , De Almeida Souza Paulo Fernando
Published: October 2021

This project promotes a dialogue between contemporary art, cinema and design, seeking to develop an audiovisual project using limited resources in the midst of the COVID-19 pandemic. The study starts from a creative process focused on a poetics materialized through masks designed in the form of sculptures and installations that are transmuted into three-dimensional performance elements, composing costumes and scenarios suitable for creative exploration in the scope of photography and audiovisual production. The narratives and aesthetics are designed with light and shadow effects, emptiness and filling, space and non-space concepts. The social isolation caused by the new Coronavirus is personified through sensations and experiences of color, light and darkness, creating a ritualistic atmosphere of transformation of the self, starting from the principles of belief and faith, in addition to a cycle of learning and unveiling in an obscure environment. The methodology used was based on design thinking strategies, interviews with creators and potential consumers, scriptwriting, scale, costume development, photomontages and prototyping of the proposed audiovisual product. Making a creative proposal during the social isolation proved to be a methodological, managerial, financial, technical and mental challenge, in view of the overload of activities for the team members and the difficulties generated by remote work, with decision-making that is often time-consuming and dense. This study is relevant for creators, producers, designers and visual artists interested in producing audiovisual products with a strong creative appeal and at the same time with limited resources, using methodologies focused on remote team work.
A relação entre imagem e som na construção do espaço sonoro da animação O menino e o mundo
Authors: De Moraes Nepomuceno Patricia Perez , Silva Gino Mauricio
Published: October 2021

The article is an analysis of the sound and musical space created for the brazilian animation The boy and the World (2013), produced by Alê Abreu. In the narrative, imagery and sound styles, the animation deals with the representation of ideas and symbols in a unique way, bringing a sound environment rich in experiments, which deserves a critical look in order to bring important contributions to this field of study. Animation is a space where all sound must be recreated, so it opens a rich field for investigation.In the methodology, we highlight some frames of the object, bringing an analysis of the relationships between image and sound. We understand that sound has its narrative particularities, with elements intrinsic to its field of research, reinforcing the importance of its own study and the relevance in relation to image production. For this, a support was sought mainly in the theories of Michel Chion and Angel Rodriguez, where we can highlight contributions to the knowledge of these correlations.The sound is far from being redundant in relation to the image, in fact, it completes and transcends the narrative, providing a more complete experience (Rodriguez 2006, 276). Therefore, we understand that a well developed sound environment built for the animation allows particularities and identity to the narrative artistic object.

Ethnicity and identity: a space for constructing reality
Authors: Хабенская Е.О.
Published: October 2021

российские этнологи обсуждали природу этнических феноменов на протяжении нескольких десятилетий, но так и не пришли к консенсусу. Пришедший на смену теории этноса западный конструктивистский подход к этничности достаточно глубоко проник в российскую науку, но почти не затронул политику. Российская национальная политика, в целом, так и осталась на уровне ленинско-сталинской трактовки нации. Хотя современные законодательные акты в этой сфере и пополнились новой терминологией, объектами «национальной политики» в России по-прежнему остаются мифические этнические общности, а не права отдельного индивида и его идентичность. Автор полагает некорректным в нынешней реальности говорить об объективном существовании этнических групп, которые не имеют ни объективных характеристик, ни понятных границ. В условиях перманентной культурной трансформации и глобализации мира единственным признаком этнической принадлежности становится этническая идентичность конкретного индивида, которая определяется индивидуальными факторами, является изменчивым, ситуативным и многослойным феноменом.

Russian ethnologists have been discussing the nature of ethnic phenomena for several decades but have not come to a consensus. The Western constructivist approach to ethnicity, which replaced the theory of ethnicity, penetrated quite deeply into Russian science, but almost did not affect politics. Russian national policy has remained at the level of the Leninist-Stalinist interpretation of the nation. Although modern legislative acts in this area have been supplemented with new terminology, the objects of "national policy" in Russia are still mythical ethnic communities, and not the rights of an individual and his identity. The author believes that it is incorrect in the current reality to talk about the objective existence of ethnic groups that have neither objective characteristics nor understandable boundaries. In the conditions of permanent cultural transformation and globalization of the world, the only sign of ethnicity is the ethnic identity of a particular individual, which is determined by individual factors, is a changeable, situational, and multi-layered phenomenon.

They made it possible to emulate the real conditions in which the relay protection devices have to function, unnecessary and to depict the characteristics of future devices. The code is presented that allows the microprocessor device to function according to the laid down algorithm. A device on a reed switch and a microprocessor is presented, which allows transmitting a certain amount of current in the primary circuit in digital form (binary code) to the microprocessor protection. The presented measuring device made it possible to implement a method for determining the magnitude of the steady-state short-circuit current.
PERCEPTIONS AND ATTITUDES OF AIRLINE EMPLOYEES TOWARDS DIVERSITY. A QUANTITATIVE ANALYSIS
Authors: NTOUMI MARIA
Published: October 2021

As the world tourism market is continuously changing, travel by air is considered the most widespread mode of mass international tourism. Considering new ways of management that airlines need to adopt in order to have a well trained and qualified management team, this survey explored the attributes of airline employees and their interactions with diverse customers, and identified the sufficient role of employees’ training and the advantages of diversity management. Simple random sampling method was applied to gather 309 airline employees’ questionnaires on their attitudes towards diversity. Descriptive and inductive analyses were used in order to present the obtained data. Principal Component Analysis was conducted to predefine three factors. Pearson correlation coefficient was applied to present the direction of the relationship between extracted factors and employee’s occupational status. Authors’ findings emphasise that airline employees seek a workplace with a friendly atmosphere that respects the diversity of employees and customers and they in their turn support airlines to operate over the comfort zone in order to achieve organisation’s goals and customers’ satisfaction. As the world keeps advancing, planning a diversity strategy should be the first step any modern-day organisation should explore prior to embarking anything related to a diverse workplace.

THE EFFECT OF TOR SIGNALLING PATHWAY ON THE RESERVE CARBOHYDRATE METABOLISM IN SACCHAROMYCES CEREVISIAE
Authors: GENÇ Tülay Turgut , GÜNAY Melih
Published: October 2021

Saccharomyces cerevisiae maya hücreleri tarafından depo karbonhidratı trehaloz ve glikojen olarak biriktirilir. Trehaloz ayrıca stres koruyucu özelliğe sahip olup ve maya hücrelerini fizyolojik streslerden korur. Maya hücreleri düşük besin içeren ortamdan zengin besin içeren ortama geçirildiğinde depo karbonhidratları hızlı bir şekilde glikoza parçalanır. Trehaloz biyosentezi TPS kompleksi tarafından ve trehaloz yıkımı nötral trehalaz enzimi tarafından katalizlenir. Glikojen sentezi glikojenin, glikojen sentaz ve dallanma enziminin aktiviteleri ile gerçekleştirilir. Glikojenin parçalanması ise glikojen fosforilaz ve glukoamilaz tarafından katalizlenir. Maya hücrelerinde TOR (Target of rapamisin) sinyal yolağı normal büyüme koşullarında farklı hücresel süreçleri ve sinyal yolaklarını aktive eder. Rapamisin ve kafein uygulamasına ilave olarak zayıf azot kaynağıda TOR sinyal yolunu inhibe eder. Bu araştırmada, TOR sinyal yolağının depo karbonhidrat metabolizması üzerindeki etkileri ?tor1 ve yaban tip maya suşları kullanılarak azot açlığında belirlendi. Azot açlığında ve normal üreme koşullarında trehaloz birikiminin yaban tip ve ?tor1 maya hücrelerinde benzer olduğu gözlendi. Mutant maya hücrelerinin glikojen birikiminin normal üreme koşullarında yaban tip maya hücrelerinden daha fazla olduğu belirlendi. Fakat azot açlığının glikojen birikimini yaban tip hücrelerde 25 kat ve mutant maya hücrelerinde 2 kat tetiklediği tespit edildi. Besin yenilenmesinin yaban tip ve mutant maya hücrelerinin trehaloz ve glikojen birikimi üzerinde değişikliğe sebep olmadığı gözlendi. Bununla birlikte, mutant maya hücrelerinde trehaloz ve glikojen birikiminin besin yenilenmesi yapılmayan ortamda devamlı olarak arttığı belirlendi. Bu sonuçlar, TOR sinyal yolağının glikojen metabolizması üzerinde daha etkili olduğunu göstermektedir. Ayrıca TOR1 geninin silinmesi ile gen ürününün inaktivasyonu trehaloz ve glikojen metabolizması üzerinde aynı etkiyi oluşturmamaktadır.

Aniden ortaya çıkan, tsunamiye benzetilen, milyonlarca insanı enfekte eden/öldüren ve tüm dünyaya yayılan COVID-19, 11 Mart 2020’de DSÖ tarafından “pandemi” olarak kabul edilmiştir. Dünyayı durma noktasına getiren ve toplumları alt üst eden COVID-19’un etkileri halen devam etmektedir. Bu çalışmanın amacı COVID-19 pandemisinin yaşlılar üzerindeki etkileri, pandemide yaşlıların bakımı ve korunması ile ilgili literatür bilgisinin derlenmesidir. COVID-19 özellikle yaşlılarda fiziksel, psikolojik ve sosyal değişikliklere yol açmıştır. Yaşlılar, COVID-19 nedeni ile bakım ve tedaviye ulaşmada güçlük yaşamış, ağır semptomlar deneyimlemiş, yoğun bakım ihtiyaçları artmış, yoğun bakım ünitelerinde daha uzun süre kalmış ve hatta yeterli beslenememişlerdir. Ayrıca, yaşlıların COVID-19’a bağlı fiziksel inaktivite, yaş ayrımcılığı, sosyal izolasyon ve yalnızlık, kronik hastalıkların yönetiminde güçlük, dayanıklılıkta azalma ve kırılganlıkta artma nedenleri ile morbidite ve mortalite oranları da yükselmiştir. Yaşlılar için özellikle sağlık hizmetleri ve sosyal koruma sistemlerinin güçlendirilmesi, bakım ve desteğe erişimin iyileştirilmesi, uzun süreli bakımın sağlanması ve dijital erişim uçurumunun kapatılması gibi konular vurgulanmıştır. Sonuç olarak pandemi döneminde kırılgan ve dezavantajlı grup olan yaşlılar göz ardı edilmemeli tüm sorunları belirlenmeli, devlet ve sağlık profesyonelleri tarafından sorunlarına çözüm bulunmalı ve oluşturulan politikaların yaşama geçirilmesinde iş birliği sağlanmalıdır.
ACCURACY OF MONTHLY AND SEASONAL FORECASTS GENERATED FOR THE TERRITORY OF LITHUANIA USING NOAA’S CLIMATE FORECAST SYSTEM VERSION 2
Authors: Bukantis Arūnas , Valaika Gytis
Published: October 2021

The objective of this paper is to assess the accuracy of air temperature and precipitation monthly and seasonal forecasts generated for the territory of Lithuania using the NOAA’s Climate Forecast System, version 2 (CFSv2) and to determine the atmospheric circulation conditions present at the time of initialization of the respective forecasts. The air temperature and precipitation data are obtained from three-month mean and monthly mean spatial anomalies during the period between 2012 and 2019. The accuracy of forecasts was performed in accordance with three criteria: range, state and the absolute error of the respective predicted anomaly. The study has shown that forecasts initialized 0–20 days in advance of the target month or season tend to be the most skilful. The accuracy of CFSv2 forecasts may be significantly impacted by the initial atmospheric circulation conditions present during the generation thereof. The study determined which phases of Arctic Oscillation (AO) and North Atlantic Oscillation (NAO) and which circulation types according to the Hess-Brezowsky classification are favourable/unfavourable for the monthly and seasonal forecasting of air temperature and precipitation.

Published: October 2021

EL CVn-type eclipsing binaries are composed of a massive A-type main-sequence primary star and a hotter B-type secondary star. This paper presents the time-series photometric and asteroseismic results of the EL CVn-type star 1SWASP J024743.37-251549.2. Well-defined eclipsing light curves were constructed by using the novel high-cadence BV data and archival TESS data, and the physical parameters of each binary component were derived by modeling the light curves. Multiple frequency analysis was performed to investigate the pulsation properties of the binary components. A reliable signal could not be detected in the high-frequency region of 100–300 day−1, unlike in the previous discovery of three frequencies around 200 day−1. This indicates that the pulsation amplitudes of the prehelium white dwarf secondary component decreased considerably. By contrast, 12 frequencies were detected in the range of 33–53 day−1. Most of them were classified as δ Sct-type pulsations originating from the primary star. Theoretical frequencies for the seismic analysis were obtained by adding the nonrotating model frequencies from the GYRE and their rotational shifts from the complete calculation approach. Grid-based fitting was conducted for various stellar properties. The theoretical frequencies and stellar parameters of the best solution concurred well with the observations. The rotation rate was constrained to 1.50 ± 0.02 day−1, indicating the synchronized rotation of the primary star. The results imply that the complete approach based on the polytropic model is applicable to the seismic analysis of fast-rotating δ Sct stars.
Studies of Cepheus X-4 during the 2018 Outburst Observed with AstroSat
Authors: Mukerjee Kallol , Antia H. M.
Published: October 2021

We present timing and spectral results for the 2018 outburst of Cepheus X-4, observed twice by AstroSat at luminosities of 2.04 × 1037 erg s−1 and 1.02 × 1037 erg s−1. The light curves showed strong pulsation and co-related X-ray intensity variation in the SXT (0.5–8.0 keV) and LAXPC (3–60 keV) energy bands. The spin period and spin-down rate of the pulsar were determined from two observations to be 65.35080 ± 0.00014 s and (−2.10 ± 0.8) × 10−12 Hz s−1 at epoch MJD 58301.61850, and 65.35290 ± 0.00017 s and (−1.6 ± 0.8) × 10−12 Hz s−1 at epoch MJD 58307.40211. Pulse shape studies with AstroSat showed energy- and intensity-dependent variations. The pulsar showed an overall continuous spin-down over 30 yr at an average rate of (−2.455 ± 0.004) × 10−14 Hz s−1, attributed to the propeller effect in the subsonic regime of the pulsar, in addition to variations during its outburst activities. Spectra between the 0.7 keV and 55 keV energy bands were well fitted by two continuum models, an absorbed compTT model and an absorbed power law with a Fermi–Dirac cutoff (FD-cutoff) model with a blackbody. These were combined with an iron emission line and a cyclotron absorption line. The prominent cyclotron resonance scattering features with a peak absorption energy of

Say Hello to Algol's New Companion Candidates
Authors: Jetsu Lauri
Published: October 2021

Constant orbital period ephemerides of eclipsing binaries give the computed eclipse epochs (C). These ephemerides based on the old data cannot accurately predict the observed future eclipse epochs (O). Predictability can be improved by removing linear or quadratic trends from the O − C data. Additional companions in an eclipsing binary system cause light-time travel effects that are observed as strictly periodic O − C changes. Recently, Hajdu et al. estimated that the probability of detecting the periods of two new companions from the O − C data is only 0.00005. We apply the new discrete chi-square method to 236 yr of O − C data of the eclipsing binary Algol (β Persei). We detect the tentative signals of at least five companion candidates having periods between 1.863 and 219.0 yr. The weakest one of these five signals does not reveal a “new” companion candidate, because its 680.4 ± 0.4 day signal period differs only 1.4σ from the well-known 679.85 ± 0.04 day orbital period of Algol C. We detect these same signals also from the first 226.2 yr of data, and they give an excellent prediction for the last 9.2 yr of our data. The orbital planes of Algol C and the new companion candidates are probably coplanar because no changes have been observed in Algol’s eclipses. The 2.867 day orbital period has been constant since it was determined by Goodricke.
X-Ray Superflares from Pre-main-sequence Stars: Flare Modeling
Authors: Getman Konstantin V. , Feigelson Eric D. , Garmire Gordon P.
Published: October 2021

Getman et al. report the discovery, energetics, frequencies, and effects on environs of >1000 X-ray superflares with X-ray energies E
X ∼ 1034–1038 erg from pre-main-sequence (PMS) stars identified in the Chandra MYStIX and SFiNCs surveys. Here we perform detailed plasma evolution modeling of 55 bright MYStIX/SFiNCs superflares from these events. They constitute a large sample of the most powerful stellar flares analyzed in a uniform fashion. They are compared with published X-ray superflares from young stars in the Orion Nebula Cluster, older active stars, and the Sun. Several results emerge. First, the properties of PMS X-ray superflares are independent of the presence or absence of protoplanetary disks inferred from infrared photometry, supporting the solar-type model of PMS flaring magnetic loops with both footpoints anchored in the stellar surface. Second, most PMS superflares resemble solar long-duration events that are associated with coronal mass ejections. Slow-rise PMS superflares are an interesting exception. Third, strong correlations of superflare peak emission measure and plasma temperature with the stellar mass are similar to established correlations for the PMS X-ray emission composed of numerous smaller flares. Fourth, a new correlation of loop geometry is linked to stellar mass; more massive stars appear to have thicker flaring loops. Finally, the slope of a long-standing relationship between the X-ray luminosity and magnetic flux of various solar-stellar magnetic elements appears steeper in PMS superflares than for solar events.

Published: October 2021

Cet article analyse les effets de la libéralisation financière sur la croissance économique au sein de la Communauté Économique et Monétaire de l’Afrique Centrale (CEMAC), sur la période 1985-2018, à partir d’un modèle AutoRegressive Distributed Lag. Les résultats des estimations à l’aide des estimateurs Mean Group (MG), Pooled Mean Group (PMG) et Dynamic Fixed Effects (DFE) montrent que le développement bancaire présente un effet positif et significatif sur la croissance dans la CEMAC à long et à court terme. À long terme, la libéralisation financière est significative et affecte négativement la croissance économique. À court terme, le crédit domestique fourni par le secteur privé a un impact positif sur la croissance, le degré d’ouverture a un impact significatif et négatif sur la croissance. Ces résultats prédisent que la CEMAC devrait encourager les crédits domestiques à court terme, réduire sa dépendance vis-vis des revenus pétroliers et diversifier davantage son économie.

Published: October 2021

Feedback may be an effective interaction provided by the intelligent tutoring system. Nevertheless, the learning feedback is not easily definable, especially in front of learners with their characteristics and preferences. In this work, the authors propose to predict personalized feedback in a programming language learning context that promotes the feedback of the ITS according to the learner preferences and learner style. The recommended method uses a combination of machine learning techniques to suggest the best appropriate feedback according to learner’s preferences and characteristics.
For that purpose, the predictive personalized feedback method will respect the following phases: collect the learning experience from the learning resources (LR) and learner preferences (LP), generate groups of clusters that contain the common characteristics using the k-means algorithm, and define the association rules between the four categories and their corresponding activity. Finally, generate the personalized feedback and propose the recommendation through the intervention of an expert in the field.

Endophytes are symptomless fungal and bacterial microorganisms found in almost all living plants. They are vital components of plant microbiomes. Endophytes affect plant growth and plant responses to pathogens, herbivores, and environmental change by producing a range of natural products having antifungal, antibacterial, and insecticidal properties. Endophytes have shown particular promise in agriculture particularly as beneficial crop inoculants and are known to enhance abiotic and biotic plant stress tolerance by increasing tolerance to drought and water stress, as well as tolerance to high temperature and high salinity. A better understanding of their plant growth-promoting mechanisms could simplify higher production of energy crops in a more sustainable manner even on marginal land and feed stocks for industrial processes, thus contribute to avoiding conflicts between food and energy production Many endophytes can be exploited to improve the efficiency of phytoremediation as they are found to be resistant to heavy metals and capable of detoxifying organic contaminants.

Published: October 2021

Nanomaterials manifest distinct physical and chemical properties and have received much attention from researchers in different areas of environmental sciences, specifically in bioremediation. However, bioremediation may not always impart contrivable approaches when subjected to high concentrations of contaminants that are harmful to most microorganisms, which include heavy metals and salts. Nanotechnology on the other hand exhibits a number of potential environmental benefits such as treatment and remediation, pollution prevention, and sensing and detection of pollutants. Nanomaterials used towards bioremediation provide less-toxic effects on indigenous microorganisms and improve microbial biodegradation activity. Credibility of nanotechnology to cut down pollution is in its developing stage and could potentially revolutionize the field of environmental sustainability. Nano-bioremediation is a new emerging technique for remediation of pollutants using biosynthetic nanoparticles.
Bacterial Remediation of Chromium From Industrial Sludge
Authors: Roy Dipankar , Mitra Arup Kumar
Published: October 2021

Chromium-like heavy toxic metals seriously influence the metabolism of living organisms and cause permanent threatening of health. Microorganisms can help to detoxify those hazardous heavy metals in the environment by the process of bioremediation. Two bacterial genera were isolated from industrial sludge designated P1 and P2. From the 16srRNA study, it is revealed that P1 is Bacillus cereus and P2 is Enterobacter sp. They are deposited in NCMR and NCBI and received the accession no. MCC 3868 for P1 and MCC 3788 for P2. P1 is gram positive, motile, and P2 is gram negative, motile. Eighteen antibiotics have been taken for antibiotic assay; P1 is resistant to 12; P2 is resistant to 8 antibiotics. For growth pattern analysis in chromium, three parameters have been selected, and they are temperature, pH, and biomass. In LD50 and above parameters, total chromium uptake by those bacteria in stressed conditions have been recorded. The two bacteria are not antagonistic to each other so they are used to bioremediate chromium from their contaminated sites and also treated as consortium.
International and Domestic Discourses of China's Special Economic Zones
Authors: Li Yichao , Costa Cátia Miriam
Published: October 2021

Although China's Special Economic Zones (SEZs) have already been widely known, they are under-studied, and the existing literature is missing certain topics such as the study of official discourses on these SEZs. What this study attempts to address are these questions: Does the Chinese political discourse on SEZ development change in both the domestic and international contexts? How does the Chinese discourse adapt to the domestic and international audiences and adjust to their conjuncture? The authors search and analyze official five-year plans for discrepancies between discourses and interpretations from ministry to ministry, and between the Chinese and English versions of the official discourse. The aim is to introduce discourse analysis to this topic, contributing to the discussion a broader description and analysis of SEZ dynamics, as well as an overview of their adjustments in accordance with the ever-evolving Chinese political and economic projects.
Extending the China-Indian Ocean Blue Economic Passage
Authors: Li Yichao , Leandro Francisco José , Figueiredo Paulo Guilherme
Published: October 2021

Currently, both domestic and overseas SEZs are key elements of the BRI and China's strategy to augment access with consent to the global community and to lay down a new blueprint for trade. The concept of a Lusophone Maritime Silk Road can be contextualised within the maritime leg of the BRI to refer to a commercial corridor which is an extension of the China–Indian Ocean–Africa–Mediterranean Sea Blue Economic Passage, which, in turn, is one of the BRI's three Blue Economic Passages. Facing significant challenges, SEZs in African Portuguese-speaking countries (APSCs) have been struggling for success, bringing only limited economic impact (there is also limited social indicators to reflect the impact). Using a theoretical-inductive perspective and mixed qualitative dominant approach, this chapter seeks to answer the main research question: What can be learned from the establishment of SEZs in APSCs in terms of performance (challenges) and experience (lessons)? The authors put forth a comprehensive model for analysing SEZs, using Mozambique's Nacala Special Economic Zone as a case study.

Mixed Methods Research
Authors: Mavodza Judith
Published: October 2021

This chapter seeks to investigate the use of convergent mixed methods design, explanatory mixed methods design, exploratory mixed methods design, embedded mixed method design, transformative mixed methods design, and multiphase mixed methods design in 61 mixed methods-based LIS doctoral dissertations and theses completed between 2006 and 2018, retrieved from the ProQuest Library Science Database. Their retrieval was achieved through search for the term “mixed methods” in the abstract, based on the assumption that each author mentions their research method in the abstract. The aim is to assess the effectiveness of mixed methods use, including advantages and possible challenges of each type. The premise for doing so is that the mixing of methods must be a deliberate, skillfully crafted, not a haphazardly concocted fusion.
Mixing Qualitative and Quantitative Evidence in a Systematic Review
Authors: Granikov Vera , Hong Quan Nha , Pluye Pierre
Published: October 2021

Mixed studies reviews are literature reviews that use a systematic approach to combine quantitative, qualitative, and mixed methods studies. Mixed studies reviews are guided by the principles of mixed methods, specifically the integration of qualitative and quantitative evidence, with the goal of leveraging their complementarity. This chapter discusses and provides methodological guidance for mixed studies reviews in information science. This contribution is valuable since empirical research in information science typically involves diverse data collection and analysis methods and many research topics can be described as complex phenomena – both cases for which the mixed studies approach is recommended. This chapter provides a detailed description of the steps involved in a mixed studies review (question formulation, eligibility criteria, identification, selection, critical appraisal, data extraction, and synthesis) and illustrates each step with a concrete example from library and information science.
Using Mixed Methods to Optimise Efficacy Measurement in Experimental Interventions Involving Human Subjects
Authors: Yafele Simbayi
Published: October 2021

Experimental mixed research remains low in library and information science (LIS) despite being embraced in other disciplines. That might be due to limited simple research exemplars to replicate. This chapter showcases mixed methods research (MMR) in an empirical, experimental study involving the multidisciplinary area of academic reading development. A quasi-experimental test design demonstrated in the hybrid inquiry sought to discover how 1st-year university students in South Africa can utilise translanguaging practices—compared to traditional monolingual ones—to scaffold academic reading and establish efficacy. The researcher applied the experimental MMR design within a sequential exploratory scheme in the reading intervention study to understand the usefulness of ‘new' translanguaging techniques in developing academic reading in higher education. The chapter is intended as an initial reference source for LIS scholars for whom it may be beneficial to use mixed methods to assess the efficacy of phenomenon on human subjects in experimental interventions.
Mixing of Research Methods in Investigating Digital Archiving Practices at Selected Public Universities in Kenya
Authors: Erima Juliet A. , Garaba Francis
Published: October 2021

Mixed methods research (MMR) is gaining prominence as a research design in the records and archives management discipline and information science field at large. Researchers, scholars, and practitioners are drifting away from the mono-method cocoon dominated by qualitative approaches and are slowly embracing MMR. This study investigated digital archiving in selected public universities in Kenya with a view to developing a framework for digital archiving in the institutions. Using MMR, data was collected from six institutions, namely University of Nairobi, Jomo Kenyatta University of Agriculture and Technology, Moi, Kenyatta, Maseno, and Egerton Universities. Preliminary findings suggest digital archiving in Kenya is still in its infancy and a lot needs to be done to streamline the practice in universities. Among other suggestions, the study recommended a systematic roll-out of awareness programmes for top officials in the institutions to bring them to a position of appreciating and supporting digital archiving initiatives.
