Edible insects, regarded as a potential contributor to food security are currently given wide consideration due to their rich protein and other micronutrients contents. In this study, protease-assisted hydrolysis proposes an economically effective approach to hydrolyse proteins from silkworm (Bombyx mori) pupae to improve its functional properties. The proteolytic activity of a novel neutral protease (265.14 U/ml) with appreciable thermal activities, was identified using 16S rDNA asStenotrophomonas maltophilia JW20 (SmNP20). The neutral protease with an apparent molecular weight of 28 kDa emerged active at pH 7 and maintained stability in pH range 6.0-8.0. The optimum temperature was 60 °C and stable at 55-60 °C, maintaining over 80% of its initial activity, with a half-life of 78.75, 89, 66.8 and 44 min at 50, 60, 70 and 80 °C. It was purified to 9.98-fold with a specific activity of 455.06 U/mg and 63.73% yield. The Km and Vmax values were 0.70 mg/ml and 9.48 μmol/min/mg, respectively. Enzymolysis with neutral protease enhanced the degree of hydrolysis (97.46±4.87%), increased water solubility over 50%, and a significant protein solubility of 63.44±0.65%. The Km and Vmax of the protein yield were 0.24 mg/ml and 165.63 μmol/min/mg respectively. A total of 17 amino acids have been detected in the hydrolysates obtained from the silkworm pupae protein. In comparison with neutrase and flavorzyme®, the enzyme possesses an elevated hydrolytic and catalytic efficiency. Emulsion activity and foam capacity ranged from 8-48 m2/g and 6-25% respectively. Hence, this study confirms the unique and efficient characteristics of an insect-enzyme correlation that is practically significant with potential improvement in nutritional composition and functional quality of insect proteins.

Published: August 2021

Farm-raised sago palm weevil (Rhynchophorus ferrugineus) larvae (SPWL) can be used as a protein source for food sustainability. This study aimed to investigate the potential of pH-shift processing as a cold refinery approach to produce protein isolate from SPWL. Maximum solubility of SPWL protein was observed at pH 2.0 (acid-aided process) and pH 11.5 (alkaline-aided process). The zeta-potential of the protein solution was close to zero with the lowest solubility at pH 4.5. So, the protein precipitation was performed at this pH. Although both acid and alkaline methods yielded roughly 66% protein, their nutritional and techno-functional features differed based on the pH-shifting process. The alkaline-produced protein isolate had higher essential amino acid (EAA) content and EAA index but it was darker in colour. The acid-produced protein isolate had larger levels of umami-taste-active and functional amino acids, as well as a higher emulsifying capability.

Our results generalize the complete moment convergence of the probability space to the sub-linear expectation space.
Des outils simples ou rudimentaires aux pratiques sociales : étude d’un cas à Chypre au Néolithique pré-céramique
Authors: Astruc Laurence
Published: August 2021

La fabrication de la vaisselle en pierre constitue un artisanat particulièrement fleurissant dès le IXe millénaire av. J.-C. au Proche-Orient et en Anatolie. Les artisans néolithiques, avant l’invention de la céramique, ont fabriqué des récipients en pierres dures ou tendres, de formes diverses, avec un répertoire iconographique parfois très riche. Les méthodes de production, l’organisation interne de cet artisanat, le statut social des individus qui y participent sont encore mal connus. Le Néolithique récent de Chypre montre, au VIIe millénaire av. J.-C., un exemple unique d’atelier de vaisselles parfaitement inséré dans un contexte domestique.

Authors: Attademo Gianluca , Maccaro Alessia
Published: August 2021

The formulation of Charts for research ethics and Codes of conduct has been growing in the last few decades, on the one hand due to a renewed awareness of the ethical dimensions of research governance and the relationship between regulators and researchers, and on the other hand for the expansion of possibilities achieved by innovation in information and communication technologies. The voluntary involvement of research participants, risk management and prevention, data protection, community engagement, reflexivity of researchers are some of the centres of gravity of a debate that involves researchers, institutions, and citizens.
Doing Research With Online Platforms
Authors: Marrazzo Francesco
Published: August 2021

The post-API age in digital research has brought immediate consequences in research activities based on (big) data owned by online platforms. Even some initiatives made by online platforms themselves, mainly based on funding specific research projects, have not found a warm reception in the research community and have been considered not enough to do research on the most relevant phenomena of the digital public sphere. Therefore, since the access-to-data has become a relevant issue even for civil society organizations and public actors dealing with digital ecosystem, a specific brand-new issue network among public institutions, NGOs, and researches has been established. The technical expertise, the shared interests, and the fulfilment of similar goals in shaping public values in the online platforms activities seem to be crucial to the permanence and even to the institutionalization of such an issue network.
Online Research Practice and Integrated Perspectives of Inquiry
Authors: Mauceri Sergio , Faggiano Maria Paola , Di Censi Luca
Published: August 2021

The authors reconstruct the system of advantages and limits of e-mail data collection and web survey technique in social research; for this purpose, they examine in detail a set of studies that stimulate multiple reflections, both with reference to the overall value of survey research and on the role of the web for social sciences. The subject of all selected research designs is a complex social problem that involves the internet, both focus for observation and tool for research: voting intentions, social effects of the pandemic, the quality of university life, technology addiction. In each research experience, for different reasons—above all due to the lack of a single, self-sufficient data collection mode—, the authors favor the integration of research strategies: 1) mixed-modes of data collection, 2) follow-up panel web survey, 3) mixed methods research, 4) introduction of a preliminary pilot study, 5) multilevel survey.

Published: August 2021

In today's world, which has been administered by computers and artificial intelligence in many areas, online data gathering has become an inevitable way of collecting data. Many researchers have preferred online surveying, considering the advantages of this method over the classical ones. Hence, the factors that may affect the response rate of online surveying have become a prominent research topic. In line with the popularity of this issue, the purpose of this chapter was to clarify the concept of online surveys; give information about their types, advantages, and usage; and investigate the factors that affect the participants' response behaviors. Besides the discussions on the theoretical framework of online surveying, an online survey aiming to determine the factors affecting the participation in online surveying was administered to a group of people to investigate the response behaviors thoroughly. The findings revealed that rs might affect ants' response behaviors to online surveys in various ways radically.
What Happens When the Way to “Follow the Medium” Changes?
Authors: Acampa Suania , Padricelli Giuseppe Michele , Sorrentino Rosa
Published: August 2021

Digital methods allow social researchers and IT professionals to work together to produce instruments to comprehend current social phenomena. To develop these tools, they felt the need to “follow the medium” by reorganizing their data collection and analysis strategies on what they learned from the medium. For many years, digital research has been based on application programming interfaces (APIs) querying, an approach based on the extraction of records of data made available by the platforms through their programming interfaces. But what happens when the way to “follow the medium” changes? This contribution addresses the methodological challenges and the potential alternatives in research activities that affect the researchers' role due to recent restrictions. Two examples of research experience conducted before the APIs' closure are proposed in order to lead towards an initial reflection on its critical effects.
Ethnography From Physical to Digital Contexts
Authors: Delli Paoli Angela
Published: August 2021

The term ethnography comes from the Greek ethnos (folk, the people, cultures) and gráphein (to write, to describe), and therefore, its literal meaning refers to the description of cultures. The current perspectives of ethnographic research are widening to digital contexts for several interrelated motivations: decolonization, globalization, information and communication technologies (ICTs). The classical loci of digital ethnography is represented by online communities, delimited digital spaces of social aggregation around a given domain of interest. However, in the last years, these privileged sites are complemented or sometimes substituted by social media sites and metadata in digital ethnographic research. As a result, new sites for ethnographic fieldwork are emerging fostering new types of ethnographic practice. The difference in digital ethnographic fields imply an internally diverse array of approaches. The chapter starts from the origins of ethnographic research to investigate its digital developments, methodological challenges, and variety of approach.
Narratives and Life Stories From the Machine to the Person
Authors: Grassi Edmondo
Published: August 2021

Contemporary society changes its social perspective from an anthropocentric environment to a space in which intelligent algorithms, present in every digital device, are increasingly acquiring a status of subject and less of object. Existential practices change at every moment, at every access to these intelligent agents who, in addition to supporting the user's requests, become anticipatory and prescient, demonstrating how it is essential, today, to sociologically analyse society through the image it gives the car. The intent of the contribution, mainly of a theoretical nature, will be to dialogue on the centrality of artificial intelligence as a leading actress of the multiple manifestations of digital cultures and practices, with the aim of renewing the debate on reflection on contemporary complexity starting from the event.

The Ethnographic Approach in the Digital Scenario
Authors: Padricelli Giuseppe Michele , Punziano Gabriella , Saracino Barbara
Published: August 2021

In this chapter, the goal is to formalize the main differences between the applications of ethnographic techniques when they are framed in virtual or digital methods. To be more systematic in presenting these differences, a synoptic table will be offered. This table will examine the main breaking points between the methods and will be used to organize a marked comparison between studies chosen from the most cited articles of the last 20 years. In addition to testing the effectiveness of the proposed classification scheme, the purpose of the comparison conducted between the most cited articles will be to highlight where the changes that have occurred can lead to advances in the method and where these changes have become new limits on which it is necessary to continue to reflect in order to develop the methods involved and place them clearly in line with the evolution of the digital scenario.
How to Study Online Networking
Authors: Corbisiero Fabio
Published: August 2021

Social media and social networks are pervasive in the daily use as well as in a number of applications. Social media and social networks are also intertwined, as the social medial platforms also offer the opportunity to develop and analyze social networks. Over the past two decades, there has been an explosion of interest in network research through social network analysis. Network research is “warm” today, with the number of articles on the topic of social media and social networks nearly tripling in the past decade. This interweaving has been a further breakthrough within field research yielding explanations for social phenomena in a wide variety of new ways. Social network analysis (SNA) has been recognized as a powerful tool for representing social network structures and information dissemination on the web. Here, the authors review the kinds of things that sociologists have tried to explain using social network analysis and provide a nutshell description of the basic assumptions, goals, and explanatory mechanisms prevalent in the field, with emphasis on SNA research methodology.
Social Semiotics for Social Media Visuals
Authors: Elhamy Hossam Mohamed
Published: August 2021

The social semiotics approach examines the meaning-making process in order to demonstrate how meaning is constructed in social actions and contexts. The rising interest of researchers in social media and its widespread use in society have both highlighted new challenges for data analysis. Social semiotics can provide a deep understanding of the visual grammar of the social media meaning-making process by assuming that this process is considered a social practice. The main objective of this chapter is to guide researchers and enable them to use the social semiotic approach as a research tool for the analysis of visuals in the social media environment. The chapter introduces the key elements, principles, assumptions, and rules of using the social semiotics approach in the analysis, understanding, and interpretations of social media visuals and how to explore the role played by visual elements in the meaning-making process in a social media within a specific social context.
Fostering Imagined Economies on Twitter
Authors: Luise Vincenzo , Lodetti Patrizio
Published: August 2021

Startups are entrepreneurial organisations that aim to develop a scalable and disruptive business. However, these small ventures operate in an environment of extreme uncertainty. The startup economy takes place in the present but is directed towards the future. This chapter critically investigates in online and offline realms the circulation of imagined futures that create causal links to bridge the gap between the present economic scenario and potential futures in the Italian startup food economy. This work adopted a mixed-method approach framed in a qualitative exploratory strategy which was designed to integrate qualitative techniques and digital methods. This work concludes by highlighting the co-evolutionary process between online and offline realms. On the one hand, online narratives allow economic actors to perform in radical uncertain economic contexts, while, on the other hand, the offline practices give legitimacy and credibility to these potential future scenarios.
To Be #Celts Today
Authors: Amatruda Francesco
Published: August 2021

The aim of this chapter is to define the characters of the online neo-Celtic Italian society, especially their religious beliefs, through the observation of their activities on blogs and social media such as Facebook and Twitter. Social media became, in fact, the main diffusion channel for these religions, replacing forums and other kinds of online communities as virtual places where people are allowed to interact with others who share their own spirituality. Within neo-paganism, some groups belonging to this religion started, during the last decade, identifying themselves with a more specific name, that is neo-Celtic instead of neo-pagan, that clearly defines the group as a part of pre-Christian cultural heritage. In this chapter, the author will attempt to define the characteristics of these neo-pagan groups focussing on their self-constructed identity and their relationship with the larger society.
Digital Methodologies for the Historiography of the History of Europe
Authors: Laruffa Alessandro
Published: August 2021

Within the historiography of history of Europe in the 20th century, it can be observed that the methodologies are mostly structured on archival research and comparative methods. Currently, the digital revolution has enabled the management of large amounts of data, information, and statistics. The history of historiography could consider the innovative methodologies for historical research like the digital humanities. This chapter reports the test of Omeka-S, an open-source content management system (CMS) specifically designed for humanities studies, on the history of European historiography. Omeka has been applied for the functions of digitisation, metadatation, and geolocation in accordance with international standards. The case study is the Association of European Historians (AsE), a network of historians from several European and non-European countries founded in 1983. The use of Omeka-S, in combination with traditional methodologies and network analysis, allows a more in-depth examination of the AsE's network and its historiographical paradigm.
Gender Democratization
Authors: Masullo Giuseppe , Delli Paoli Angela , Tomasiello Sara
Published: August 2021

Misogyny and gender violence are the result of social and cultural predetermination of gender roles. Indeed, eradicating role prescriptions is a real revolutionary action which implies escaping from male and masculinity hegemony and rethinking male identities. It is therefore crucial to create pathways of democratization of gender that aim to create real paths of equality between genders abandoning the social predetermination of gender roles. This challenge has become the goal of some social promotion associations which try to break down gender-based violence and the stigma attached to it. The chapter aims to investigate how these associations operate to democratize gender through a content analysis of messages posted on their respective Facebook pages. The unit of analysis of the study is constituted by the last 200 posts produced in these two Facebook pages for a total of 400 posts analyzed. Findings identify renewed spaces of masculinity (for example fatherhood) not adhering to the main stereotypes.
National Differences and Gender Stereotypes in Days of Empire
Authors: Maiello Giuseppe
Published: August 2021

Days of Empire is a freemium mobile strategy video game developed and published by the company ONEMT, whose actual headquarters is in Fuzhou Fujian, China. The company specializes in fantasy video games mostly set in the Middle East and full of references to the history and mythology of the Arab and Turkish peoples. The objective is to provide a description of the game and to perform a qualitative analysis of the attitudes of selected players towards the game, their emotional drivers, and the financial commitment many of them undertake to achieve greater success in the game. As many discussions take place in the chat function of the game, the author is interested in stereotypes referencing the players' country of origin, gender stereotypes, and even the sexual harassment to which female players are subjected. Using the emic approach, an insider's perspective will be shown of the ways in which the players of Days of Empire look at the issues of nationalism and gender stereotypes, and the emotional connection between single individuals and a freemium game of this type.
Composed Cognitive Maps
Authors: Castro Aniyar Daniel
Published: August 2021

Composed cognitive maps are a tool based on grounded theory and on Lynch's urban model of cognitive maps, which allow the transfer of information from ethnographic situations to general patterns, and to the so-called spatial dynamics. In criminological matters, they have been applied in the context of environmental and criminology of place to identify criminal situations, criminal patterns, and spatial dynamics of crime. The latter concept has allowed reliable diagnoses for the design of criminal policies. Their advantages are compared with traditional criminometric methods. It introduces a brief compilation of the existing literature on the subject. In a special way, this chapter shows how composed cognitive maps allowed the measurement of drug trafficking networks, police intelligence, and, above all, crime reduction.
Exploring Student Support in a Completely Online Module Within an Open Distance eLearning Institution
Authors: Nene Jabulani Owen
Published: August 2021

Most first-year students lack technological skills, which hampers their learning. Within the University of South Africa (UNISA), as an open distance and e-learning (ODeL) institution, first-year students require support to succeed, particularly because they are responsible for managing their own time and studies. Using a signature course, such as ‘Language through an African Lens' (AFL1501), which is a completely online module offered by the College of Human Sciences, the author explores how qualtrics data and narrative analysis aid students in completing their coursework. The article further touches on the significance of UNISA tools and other online resources as fundamentals of connectivism, the theory of technology as an extension of human faculty, and transformative learning theory as a support mechanism. The contributions of the lecturer and teaching assistants in facilitating first-year students' success in the online module are invaluable, as is evident from this report involving 600 survey respondents from Unisa.

Published: August 2021

Based on the immense importance of technology acceptance among the teachers and its vital role in education, the current study aims to bridge the theoretical gap by investigating the association between the school teachers' perception of facilitation learning environment and learning through experimentation among senior school teachers in Indonesia. Data was collected from the senior school teachers of Indonesia using a cross-sectional field survey. The final dataset of 163 respondents was then analyzed using SmartPls3 to test the measurement and structural models. Results revealed that the external variables like facilitation learning environment and learning through experimentation were positively associated with the perceived usefulness, perceived ease of use, and actual use of the educational technology among the senior school teachers. This study provided insights that the technology supportive learning through experimentation gives a feeling of comfort and ease to teachers, further leading towards the actual usage of modern technology in classroom settings.

Dreaming during COVID-19: the effects of a world trauma
Authors: Marogna Cristina , Montanari Emanuele , Contiero Silvio , Lleshi Klodjana
Published: August 2021

On March 11, 2020, the World Health Organization (WHO) declared a state of health emergency affecting the entire world population. Given the serious practical and psychological difficulties and complications that have been experienced during this period, many scholars have created hypothesis, as a consequence, an increased possibility of developing post-traumatic stress disorder (PTSD) within the general population with significant implications for one’s dream activity. Participants in the study were recruited via the instant messaging application ‘WhatsApp’ for a period of 14 days. The study consisted of three phases: the first phase provided information on the purpose of the research and how to carry it out; in the second phase, each participant, using the Bionian model of dream experience as a focus, was asked to write down dreams, emotions and free connections/associations related to the dream. At the end of the collection, the texts obtained were analysed by means of a qualitative analysis performed with the aid of the MAXQDA software. The study confirms the computational and exploratory analysis of the text carried out in the research of Pesonen et al. (2020), finding also in our sample the presence of the hypothesized clusters going to explain the manifestation of imagery related to COVID-19 also within the dream activity. To confirm this, the nightmare of participant number 6 of the study is reported. The following qualitative research has offered an insight into the traumatic nature of the COVID-19 pandemic, showing how many unmetabolized ‘daytime elements’ have been reproposed in the dream scenario, recalling the symptomatology of PTSD through the presence of distressing content that affect the quality of sleep and the daily life of the individual.

Published: August 2021

There is an increasing need of outcome measures for young people suitable to evaluate treatments and routine settings. However, measures must show suitable psychometric characteristics for such use. This is the first psychometric evaluation of the Italian version of the Core Young Person Clinical Outcomes in Routine Evaluation (YP-CORE). Data are reported for a clinical sample, aged 11-17 (n=175) and non-clinical sample, aged 11- 17 (n=206). Analyses included acceptability, confirmatory factor analysis, internal reliability, influence of gender and age on cutoff scores and reliable change. The YP-CORE acceptability was good, with a very high completion rate (98.7% fully completed). Internal consistency was good: the overall Cronbach’s alpha value (α) equal to 0.75 (95% confidence interval=0.69-0.80). The measure was sensitive to change (Cohen dz=1.35). The Italian version of the YP-CORE showed acceptable psychometric properties is suitable for use in services for young people as a change/outcome measure.

The role of mechanical bowel preparation in patients undergoing elective ileostomy closure
Authors: Singh Amandeep , Singh Sarbjeet , Saini Girish , Sinha Shourabh , Kaur Haramritpal , Singh Sonam
Published: August 2021

Background:

Mechanical bowel preparation (MBP) includes cleansing of intestine from its contents by giving oral preparations before surgery to clear fecal material from bowel lumen. It had many proposed advantages that lacked evidence. Recently, due to many notable side effects, the use of MBP had been questioned. This study was performed to compare the surgical outcome with MBP and without MBP in ileostomy closure surgeries.

Materials and Methods:

The study was conducted on 80 patients who had ileostomy for more than 3 months. They were randomly divided into two groups of 40, each using computer-generated randomization. Group A patients received MBP on the evening before elective ileostomy closure while Group B patients did not receive any MBP. Postoperatively, patients were kept in the ward and monitored for any complications and total duration of stay in hospital.

Results:

The mean postoperative duration of paralytic ileus after ileostomy closure surgery with bowel preparation is 4.1 ± 1.4 days. Without bowel preparation, it is 3.9 ± 1.5 days (P > 0.05). The number of patients with anastomotic leak is 3 (7.5%) in the bowel preparation group and 3 (7.5%) in the group without bowel preparation (P > 0.05). Wound infection is present in 7 (17.5%) patients in the bowel preparation group and 10 (25%) patients in the group without bowel preparation. The number of patients needing surgical intervention in the course of management is 2 (5%) in Group A (with MBP) and 3 (7.5%) in Group B (without MBP). The mean duration of hospital stay with bowel preparation is 10.6 ± 3.6 days and without bowel preparation is 10.8 ± 3.5 days (P > 0.05).

Conclusion:

The above study concludes that there is no influence of MBP on surgical anastomosis in ileostomy closure surgeries.
On restriction of unitarizable representations of general linear groups and the non-generic local Gan–Gross–Prasad conjecture
Authors: Gurevich Maxim
Published: August 2021

We prove the first direction of a recently posed conjecture by Gan, Gross and Prasad, which predicts branching laws that govern restriction from

p

-adic

GL_n

to

GL_{n-1}

of irreducible smooth representations within the Arthur-type class. We extend this prediction to the full class of unitarizable representations, by exhibiting a combinatorial relation that must be satisfied for any pair of irreducible representations, in which one appears as a quotient of the restriction of the other. We settle the full conjecture for the cases in which either one of the representations in the pair is generic. The method of proof involves a transfer of the problem, using the Bernstein decomposition and the quantum affine Schur–Weyl duality, into the realm of quantum affine algebras. This restatement of the problem allows for an application of the combined power of a result of Hernandez on cyclic modules together with the Lapid–Mínguez criterion from the

p

-adic setting.
Exterior powers in Iwasawa theory

Published: August 2021

The Iwasawa theory of CM fields has traditionally concerned Iwasawa modules that are abelian pro-

Galois groups with ramification allowed at a maximal set of primes over

p

such that the module is torsion. A main conjecture for such an Iwasawa module describes its codimension one support in terms of a

-function attached to the primes of ramification. In this paper, we study more general and potentially much smaller modules that are quotients of exterior powers of Iwasawa modules with ramification at a set of primes over

p

by sums of exterior powers of inertia subgroups. We show that the higher codimension support of such quotients can be measured by finite collections of characteristic ideals of classical Iwasawa modules, hence by

Habitual cold-water swimming and upper respiratory tract infection
Authors: Collier N. , Lomax M. , Harper M. , Tipton M. , Massey H.
Published: August 2021

It has long been claimed that non-wetsuit cold water swimming (CWS) benefits health (1), and anecdotally cold-water swimmers claimed to suffer fewer and milder infections, though this was not directly measured. A boost to immunity is biologically plausible: stress hormones are released during cold-water immersion (2), and short-term stress may ready the immune system for injury or infection (3). However, very few studies have investigated immune system markers and/or actual illness in habitual cold-water swimmers.

V članku je obravnavan zakon o podelitvi mestnih pravic flavijskemu municipiju Irni (t.i. lex Irnitana) v današnji španski provinci Sevilli. Besedilo poznamo po zaslugi šestih bronas­tih plošč odkritih leta 1981 na lokaciji antičnega mesta, deli drugih dveh mestnih pravic Salpenze in Malake, ki se deloma prekrivajo z ohranjenimi poglavji lex Irnitana, pa kažejo, da vse tri sledijo istemu krovnemu zakonu iz obdobja flavijskih cesarjev. Po zaslugi navedenih kopij poznamo približno tri četrtine celotnega besedila, oz. 73 od 97 poglavij. Besedilo posameznih poglavij zakona govori o magistraturah, volitvah, mestnem svetu, ki je štel v Irni 63 članov, upravnih in finančnih zadevah, sodstvu, izbiri sodnikov v civilnih procesih idr. Sodstvo je veljalo za pravi kriterij mestne avtonomije in kot tako zavzema z poglavji od 84 do 92 več prostora kot katerokoli drugo področje.

Splošni opomin (Admonitio generalis) je kapitular (frankovski zakonodajni odlok) Karla Velikega (vladal 768–814), ki je bil temeljni dokument njegovega programa kulturne prenove (renovatio). Kapitular je bil izdan 23. marca 789. Čeprav je v prvi vrsti ideološke narave, ni ostal le mrtva črka na papirju: še istega leta so ob njem izšli trije drugi kapitularji, ki so ga vsebinsko dopolnjevali (Duplex legationis edictum, Capitulare missorum, Breviarum missorum Aquitanicum). Kapitularje so frankovski vladarji sicer izdajali že prej, vendar še nikoli več kot dva v istem letu. Prav tako so se kmalu po izdaji Admonitio generalis v različnih delih kraljestva zvrstile sinode, ki pred tem v frankovskem kraljestvu niso bile tako pogoste. Na teh zborovanjih je bil program, začrtan v Admonitio generalis, konkretiziran in uveden v prakso.
Podoba Julijana Odpadnika v zgodovinopisju Amijana Marcelina
Authors: Bembič Ana
Published: August 2021

Julijan Odpadnik je bil rimski cesar, ki je v četrtem stoletju, ko se je krščanstvo pod Konstantinom že uveljavilo, skušal preobrniti zgodovino nazaj v čas poganstva. Njegova vladavina je bila kratka in nepričakovana, zanjo pa so bile značilne verske reforme in vojaški pohod nad Perzijo. Krščanski pisci ga prikazujejo negativno, za poganskega zgodovinopisca Amijana Marcelina pa je predstavljal podobo idealnega vladarja. V svojem zgodovinopisnem delu Res gestae je Julijana prikazal kot izbranca bogov. Kljub občudovanju mu ni prizanesel s kritiko, je pa načrtno zmanjševal pomen verskih in drugih zadev, ki bi lahko škodovale njegovi podobi. Da bi mu povečal veljavo, ga je primerjal z mnogimi slavnimi osebami iz grške in rimske preteklosti, prejšnjega cesarja Konstancija in Julijanovega brata Gala pa je prikazal izrazito negativno. Kljub naklonjenosti bogov pa je Julijan na pohodu proti Perziji zavrnil vsa svarilna znamenja, kar ga je stalo življenja. Njegovo smrt Amijan vzporeja s Sokratovo smrtjo in ga s tem prikaže kot vladarja filozofa, kar se ujema z Julijanovim lastnim idealom.
A Geographic Theorization of Zongos in Urban Ghana: A Complex Systems Approach
Authors: Mensah Joseph , Teye Joseph Kofi
Published: August 2021

While Zongos have become a permanent abode for many people, especially migrants in urban Ghana, the dynamics of these communities are quite poorly understood. This paper provides a geographic analysis of the formation of Zongos, drawing heavily on a complex systems approach to explore how various variables, including space, ethnicity, class, citizenship, migration and environmental processes intersect to form and sustain Zongos in Ghana. Essentially, the paper throws more light on the key factors that contribute to the spatial concentration of the urban poor in Zongos and concludes with the consequences of having the urban poor living in highly segregated and economically depressed neighbourhoods in Ghanaian cities. The paper argues that the formation of Zongos is not solely attributable to the fondness of migrants from northern Ghana to live among people of like background while in southern cities, but also because of the exclusionary machinations of the majority and their housing gatekeepers.

This study examined and compared the objectively-weighted, expert-based-weighted and stakeholder-based weighted Scalogram approaches based on their centrality indices and factors considered in assigning weights to the functions. A mixed-method approach, comprising both quantitative and qualitative techniques were employed to gather primary and secondary data for the study. All the three Scalograms with different weighting techniques were analyzed in Microsoft Excel, focusing on centrality and weighted centrality indices and simple linear regression models. The study discovered that the grand total centrality index of the objective Scalogram is 4,105.60, the expert-based Scalogram is 10,294.2 while the stakeholder-based one is 10,429.80. The co-efficients of determination for the three are 0.9892, 0.9757 and 0.9812 respectively, giving explanatory powers of 98.92%, 97.57% and 98.12% respectively. It is recommended that due to resource constraints, planners should rely more on the objective-based approach, followed by the stakeholder-based approach and then the expert-based approach, since the latter approach has rather reduced the explanatory power of population by increasing values of the centrality indices. Again, bottlenecks to the development of Area Council headquarters (intermediate settlements between Wa and lower-level settlements) should be tackled for efficient spatial distribution of functions. The contribution of this article to the spatial and development planning literature is its juxtaposition of the three techniques in Scalogram analysis.
Research on Speech Recognition Method in Multi Layer Perceptual Network Environment
Authors: Zhao Kai , Wang Dan
Published: August 2021

Aiming at the problem of low recognition rate in speech recognition methods, a speech recognition method in multi-layer perceptual network environment is proposed. In the multi-layer perceptual network environment, the speech signal is processed in the filter by using the transfer function of the filter. According to the framing process, the speech signal is windowed and framing processed to remove the silence segment of the speech signal. At the same time, the average energy of the speech signal is calculated and the zero crossing rate is calculated to extract the characteristics of the speech signal. By analyzing the principle of speech signal recognition, the process of speech recognition is designed, and the speech recognition in multi-layer perceptual network environment is realized. The experimental results show that the speech recognition method designed in this paper has good speech recognition performance
Analysis of Financial Statement and Prewarning of Audit Risks Based on Artificial Neural Network
Authors: Zhang Yanxia
Published: August 2021

The marketization of social capital has resulted in frequent audit failures, and financial statement frauds. One of the key steps of auditing is the identification of material misstatement risk of financial statement. However, there is no unified analysis framework or quantitative method for identifying this risk. Therefore, this paper aims to analyze financial statement and prewarn audit risks in an accurate manner. Firstly, the items of financial statement were analyzed in three aspects of the target enterprise: balance statement, income statement, and cash flow statement. Next, the authors probed deep into the core indices of the post audit risk verification and evaluation of the business process, constructed a scientific evaluation index system for audit risks of financial statement, and quantified the 89 tertiary indices, 21 secondary indices, and 3 primary indices. After that, an audit risk prediction model for financial statement was established based on neural network. Experimental results show the effectiveness of the proposed model for audit risk prewarning, and applicable to other tasks of financial auditing.
METİN MADENCİLİĞİNİN TALEP PLANLAMADAKİ ROLÜNÜN İNCELENMESİ
Authors: IŞIKLI Erkan
Published: August 2021

Uzun dönem kârlılık ve müşteri memnuniyeti açısından en parlak ürün çeşitlerini belirlemek, günümüz imalatçıları için stratejik bir öneme sahiptir. Bu amaç doğrultusunda, dış çeşitliliği azaltmayı sağlayan çeşitli işlemsel modellere ihtiyaç duyulur. Özellikle ana ve ikame talebin belirlenebilmesi için geliştirilecek talep tahmin modelleri kritik öneme sahiptir. Ancak, yapılandırılabilir ürünlerde olduğu gibi kestirilecek parametre sayısı fazlaca olduğunda, bu modeller genellikle “boyutsallık lanetine” maruz kalır. Yapılandırılabilir ürünler, önceden tanımlanmış ürün özelliklerinin çeşitli kombinasyonlarıdır. Çok sayıda ve derinlikteki ürün özelliği, talep tahmin sürecini rahatlıkla zorlaştırabilir çünkü teorik olarak böyle bir ürün milyonlarca farklı kombinasyonda yapılandırılabilir. Bu çalışmada, yapılandırılabilir bir ürün için müşteri değerlendirmeleri kullanılarak, büyük miktarda kritik bilgi kaybetmeden ürün özelliklerinin sayısını azaltıp talep tahmini sürecinin nasıl desteklenebileceği tartışılmıştır. Başvurulan çeşitli metin madenciliği tekniklerinin ürettiği sonuçlar, talep modelleri oluşturulurken, bu gibi niteliksel modellerin daha iyi bir çıkarım ve öngörü elde etmek için kullanılabileceğini göstermektedir.

Günümüzün vazgeçilemez unsurlarından olan elektrik enerjisi için kısa dönemli elektrik tahminleri, son yıllarda yüksek öneme sahip konular arasında yer almaktadır. Elektrik üretimi ile talebin dengelenebilmesi için elektrik talep fiyatlarının doğru tahmin edilmesi önemlidir. Söz konusu denge kurulabildiği takdirde tüketicilere rekabetçi fiyatlar sunulabilmektedir. Elektrik talebinde doğru tahminler yapabilmek için literatürde bazı teknikler kullanılmaktadır. Bu çalışmanın amacı, söz konusu tekniklerden yapay sinir ağını (YSA) uzun kısa dönemli bellek (LSTM) mimarisiyle çalıştırarak kısa süreli elektrik talep tahmininde bulunmaktır. YSA metodolojisinin uygulanmasıyla elde edilen sonuçlar kök ortalama kare hatası değerlerine göre zaman serisi analizi (ARIMA) ile karşılaştırılmıştır. Bu bağlamda, İspanya'nın 2015-2016 yılları arasındaki elektrik verileri tahminleme yapmak için kullanılmıştır. Elektrik enerjisi üretim ve tüketim verileri, İletim Hizmeti Operatörü (TSO) verilerini içeren ve açık erişimli bir portal olan ENTSOE'den toplanmıştır.

Tekstil sektörü dünya çapında çok geniş bir pazara sahiptir ve her geçen gün müşteri ihtiyaçları ve beklentileri yükseldiği için tekstil fabrikalarının müşteri isteklerine hızlı cevap verebilmeleri gerekmektedir. Bu çalışmada, bir tekstil fabrikasının dikim atölyesindeki montaj hattı dengeleme ve performansa dayalı işçi atama problemleri birlikte ele alınmıştır. Problemin çözümü için, M1, M2 ve M3 olmak üzere üç farklı matematiksel model geliştirilmiştir. M1 modelinde, iş ve işçi sayısı eşit alınarak açılacak istasyon sayısı ve işlerin tamamlanma süresi en küçüklenecek şekilde bir montaj hatları dengelenmiş ve işçi ataması yapılmıştır. M2 modeli, işletmeden alınan veriler doğrultusunda her işe bir veya birden fazla işçinin atanabildiği doğrusal olmayan bir matematiksel modeldir. Son model ise (M3), doğrusal olmayan modele (M2) sezgisel kısıtlar eklenerek elde edilmiş alternatif doğrusal bir modeldir. Pantolon hattı verileri kullanılarak M1, M2 ve M3 ile GAMS programında elde edilen çözümler kıyaslanmış ve tartışılmıştır.
