Peter Greenaway: A Demonstration of Research-Based Art With an image essay by Amir Avraham
Authors: Lutters Jeroen , Avraham Amir
Published: October 2020

Does artistic research differ from scientific research? And if so, how? In an attempt to answer these questions, my starting position is that when it comes to artistic research, we should use 'research' to achieve a specific goal—i. e., making better art. But at the same time,
when we use 'art' in 'scientific research,' the goal will always be science. By that I mean science defined as the search for truth, and art as the search for the aesthetical. I am, of course, aware that this is an extremely binary categorisation, but I do hope it gives us some didactic clues
to work in the domain of art research. By introducing research-based art as a concept, I even hope to narrow the gap. In examining research-based art as a method that uses research for the purpose of making art, I use Peter Greenaway's film The Cook, The Thief, His Wife & Her Lover
(1989) as a case study. Here, we see both the artist as a researcher and art research as research-based art—an artist-researcher who creates an independent artistic composition by using at his own discretion the accepted results of research.
Taste: The Lost Sense, or Why the Culinary Arts Should Integrate with Art Education (a Conversation)
Authors: Klosse Peter , Sonderen Peter
Published: October 2020

This conversation inquires why the culinary arts—representing the sense of taste in relation to food—have hardly found ground in art education. The optical, the audible, the touchable and moveable have found fertile ground in all kinds of art disciplines, whereas the sense
of taste and tasting, historically connected to the aesthetic judgment of artistic objects par excellence, has hardly found refuge for its proper object, i. e., food. This conversation shows that the field of taste and food has much in common with many aspects of the arts. Although there have
been (and increasingly are) experiments with food in fine art and design, there were hardly any serious attempts to integrate the 'art of cooking' or the 'art of the culinary' into art education. Just like the art of architecture provides ideas and designs for a basic human need—i. e.,
housing—the art of the culinary should provide ideas and designs for this other basic human need—food. This lack or omission has become increasingly critical nowadays because of the controversial role the food industry plays in our appreciation and judgement of food. The food industry
has invested a lot of money to inquire about the role and workings of taste, but it has deliberately kept this knowledge for itself. It is, therefore, time that in our age of food crises, new knowledge domains be opened to develop new vistas for food and food production. The art university
with its expanding interest in research in and through the arts can provide both an interesting and necessary environment for a genuine art of taste and tasting. Taste and food, and the other senses, would be working together in an entanglement of fresh frames of thought and practices.
Art Research and Food Technology: From Historical Reflections to Creative Speculations
Authors: van den Eijnde Jeroen
Published: October 2020

This article is an introduction to three contributions about research related to food and technology. The text introduces the reader to different forms of research from historical reflections, applied action research based on new technologies, and artistic speculations. The author places
these different research approaches in the context of the Dutch scientific and higher vocational education, focussing particularly on art academies.
 This edition of APRIA considers to what extent art research can contribute to our relationship with food. This immediately
raises the question of the defining nature of art research. For some time now, Dutch arts education has been pondering how art or artistic research relates to academic research in universities. The desire of Dutch art academies to present themselves as fully fledged research institutes, preferably
with a third level of graduate research, is closely related to their status within the higher professional education sector and to their own history. Owing to their orientation towards professional education, Dutch higher vocational education institutes have focussed on practice-based research
since the introduction of research groups in 2002. In most cases, that means that these institutions utilise existing scientific and technological know-how for innovations intended to have an economic or societal impact in close collaboration with businesses and public agencies. So-called
'fundamental knowledge development' is seen as the exclusive preserve of universities.
 However, arts education in the form of an institute where students learn how to produce art has no counterpart within university education in the Netherlands. Moreover, the history of visual arts
education reveals that its origins and rationale reside in large part in theorising about and reflecting on artistic production that occurs inside and outside the walls of the academy. Fundamental knowledge development relating to artistic production should, therefore, logically take place
within arts education. Thus, in the Netherlands, the answer to the question as to the precise nature of art research is strongly influenced by institutional, political, and, as a result, financial interests. In my opinion and based on practical experiences, the academies of art have more in
common with the curious and critical driven nature of academic education, and less with the strong focus on a specific field of a métier that still dominates the higher vocational education profile.
Mia Couto: escrita e racismo — ou “a arrogância de um único saber”...
Authors: Cruz Pereira José Paulo
Published: October 2020

Seguimos aqui a distinção estabelecida por Mia Couto entre a escrita como criação literária — um modo de “descoberta da alteridade” — e a escrita como dispositivo técnico e valor cultural que dela nos pode privar. Tomada em sentido metafísico, enquanto representação secundária e exterior do signo — “um significante do significante” —, a escrita é criticamente retomada, por Jacques Derrida, como traço interno à própria linguagem. É também do mesmo ponto de vista crítico que leremos, não apenas Michel de Certeau, em L’Écriture de l’histoire, acerca de uma modernidade colonial marcada pela oposição binária escrita/oralidade, mas também a ideia de Mia Couto de que, se cultural e politicamente dada como fonte de um “único saber”, o sentido comum de escrita pode revelar-se como um último reduto do racismo.
The Targets and Motives of Orientalists Statements about Gharaneeq Story
Authors: Sanaullah Dr , Jadoon Saeed ul Haq
Published: October 2020

The former orientalist conceived that the Holy Quran came as a result of
efforts done by prophet, but there are orientalists who believe that it was not
due to the efforts by human but it came over the passage of time. Generally,
the orientalists made every effort to affront the true and holy image of last
prophet PBUH-the final messenger of Allah as well as the Quran, (revealed
words of Allah) in a bid to create ambiguity and hurt the reliability of both.
They also left no opportunity to touch and allegedly refer to as Satanic
verses. Some of them who are more significant in paying heed specifically to
this issue in their work are Karen Armstrong, Montgomery Watt and
Maxims Robinson. According to objective of their work is to prove this
fallacy that Quran does not come due to revelation from Allah. But, most
famous Muslim scholars like Al-Qurtabi, Al-Radi, Qadi Ayaz and Ibn alArabi provided proofs that this is only myth and Satanic verses have no base
at all. The article is focused to analyse the Orientalists views on the satanic
verses and their drastic failure in upholding their objectivity pertaining to the
false story. This research paper is intended to study that how they failed in
proving the major objectives of the false story.

Published: October 2020

Islam is a complete code of life which provides us guidance and awareness
in all fields of life. Amongst the Islamic science, law of inheritance is the
most important one. Its importance can be assessed from the very fact that it
is that science which has been discussed in detail by Allah in Quran.(Shares
of all relatives etc. have been specifically identified in Quran). Through this
science Islam has facilitated all of the heirs to receive their shares as per
their proportions equally without any distinction on the basis of social
position i.e. poor or rich any other consideration. However “here are a few
commandments of Islamic science of inheritance regarding which different
points of views have been presented by Shia'a sect as compared to that of
Ahl-e-sunnat Wal-Aljumaat e.g: Awal (a kind of slaves) Ta'aseeb i.e. the
relatives from father side, the inheritance of elder son, of the widow ‘and
the grand son from daughter side. In this article we are going to discuss all
of the details regarding the disputed points along with the issues on which
these two sects have agreed (do not have any difference).
Feature of Al-Tibaq in the Three Surah of Holy Quran (Surah Al-Zumur, Surah Al-Ghafir & Surah Al-Fasilat)
Authors: Jan Ahmad Saeed , Ullah Burhan
Published: October 2020

The Holy Quran containing full of wonders beauty (al-muhassinat albadi’iyyah), one of the most prominent kind of this muhassinat is Tibaq
which is called as Al-Tibaq in rhetoric. It is important for a literature scholar
to search around this kind in the various Sura’h of the Holy Quran and
clarify Tibaq. As researchers we have selected the topic: Feature of Al-Tibaq
in the three Surah of Holy Quran. (Surah Al-Zumur, Surah Al- Ghafir &
Surah Al-Fasilat). The researchers tried their best to derive and clarify the
Al-Tibaq feature from the verses in these surahs. This result to show
wonders beauty of Al-tibaq through the explanation of the related verses
from the (Surah Al-Zumur, Surah Al- Ghafir & Surah Al-Fasilat).
Synthesis of 4-substituted azopyridine-functionalized Ni(II)-porphyrins as molecular spin switches
Authors: Ludwig Jannis , Moje Tobias , Röhricht Fynn , Herges Rainer
Published: October 2020

We present the synthesis and the spin switching efficiencies of Ni(II)-porphyrins substituted with azopyridines as covalently attached photoswitchable ligands. The molecules are designed in such a way that the azopyridines coordinate to the Ni ion if the azo unit is in cis configuration. For steric reasons no intramolecular coordination is possible if the azopyridine unit adopts the trans configuration. Photoisomerization of the azo unit between cis and trans is achieved upon irradiation with 505 nm (trans→cis) and 435 nm (cis→trans). Concurrently with the isomerization and coordination/decoordination, the spin state of the Ni ion switches between singlet (low-spin) and triplet (high-spin). Previous studies have shown that the spin switching efficiency is strongly dependent on the solvent and on the substituent at the 4-position of the pyridine unit. We now introduced thiol, disulfide, thioethers, nitrile and carboxylic acid groups and investigated their spin switching efficiency.

Sejarah Islam pernah mencatat bahwa umat Islam pernah mengalami masa kejayaan dalam bidang sains ini dan tidak ada permasalahan serius terkait dikotomi sains dan agama kala itu. Umat Islam masa itu bisa menjalankan penelitian tentang fenomena alam, tanpa harus “melepas baju” keimanannya. Bahkan motivasi utama mereka dalam penelitian dan observasi adalah untuk menyingkap ayat-ayat Allah dan kekuasaan-Nya yang Maha agung. Hal yang paling penting dari dari pembahasan integrasi sains dengan agama adalah menggali kembali nilai-nilai utama dan petunjuk-petunjuk utamanya tentang sains yang merupakan salah satu cabang keilmuan dalam Islam.
Impact of a Pharmacist-led COPD Clinic on Patient Outcomes in a Rural Healthcare Clinic
Authors: Russell Sarah , Johnson Steven , Mills Elizabeth
Published: October 2020

Background
While it is well documented that pharmacists improve disease state outcomes, there are currently no studies evaluating a pharmacist’s impact on quality of life (QOL), lung function, and adherence in COPD patients, specifically in a rural healthcare setting. We aimed to compare changes in patient QOL with and without participation in a pharmacist-led COPD clinic in a rural healthcare setting.
Methods
This was a single-center, prospective, open-label, case/control study performed at a rural healthcare center during December 2018 through June 2019. Enrolled patients were assigned to either the case or control arm on an alternating basis. Case participants received individualized patient care including PFT, QOL assessment utilizing the St. George’s Respiratory Questionnaire (SGRQ), disease state education, and medication management for a total of 3 appointments during a 6-month period. Control subjects did not receive the individualized intervention during the 3 appointments and only completed the PFT, SGRQ, and medication adherence counseling.
Results
A total of 20 patients participated in the complete 6-month COPD clinic. At the end of the 6-month clinic, there was not a statistically significant difference between the groups in regard to SGRQ values (p=0.191), medication adherence (p=0.279), and lung function (p=0.321). Limitations included randomization methods and sample size.
Conclusions
Although there was not a statistically significant difference between the groups; significant mediation management interventions were made for participants in both the intervention and control groups. Pharmacists are well positioned in multiple practice settings to contribute to the improvement of quality of life for these patients.
Manoeuvring the Complexities of Field Research in Africa: Experiences from Voter Turnout Research in Ghana
Authors: Agbele Fortune , Stroh Alexander
Published: October 2020

Field research enables interaction between a researcher and research participants, offering an opportunity for the discovery of primary empirical data. As exciting as field research can be, for a novice researcher or research in unfamiliar terrain, community field research can also be daunting. These challenges may include, but are not limited to, the determination of community entry strategies, identification of potential respondents, as well as dealing with the non-availability of respondents. Based on field experiences, this research note offers practical suggestions on how to deal with these challenges within the realm of political science fieldwork. The experiences from a Voter Turnout research in Ghana shared in this note are of particular relevance to field research designs in the subject area of voter participation, focusing on voters as informants rather than experts or members of a professional network. Keywords: Field Research; Political Science; Field Strategies; Voter Turnout.
A política das máquinas: vieses em algoritmos de relevância pública
Authors: Schuler Luis Gustavo Bier , Montardo Sandra Portella
Published: October 2020

As práticas da vida cotidiana estão sendo cada vez mais reproduzidas sob a mediação de plataformas digitais (JURNO e DALBEN, 2018). Neste contexto, Algoritmos de Relevância Pública (ARP) determinam qual informação é relevante para os usuários, função de extrema importância para a sua participação nos grupos sociais (GILLESPIE, 2018a). Deste modo, problemas que já ocorrem nas sociedades contemporâneas, como preconceito racial, de gênero, classe social e outros enraizados na sociedade podem repercutir neste meio. O presente estudo busca refletir sobre como os ARP podem conter vieses e reproduzir preconceitos, observando alguns dos fatores que possam contribuir para este processo, através de uma revisão crítica da literatura. Observa-se, através dos resultados das pesquisas analisadas, que a origem destes problemas perpassa a tecnologia dos algoritmos, revelando que ainda há muito a ser feito para que se alcance o fim da desigualdade social reproduzida nas plataformas digitais.

Authors: Knapp Sandra , Chiarini Franco , Cantero Juan J. , Barboza Gloria E.
Published: October 2020

Since the publication of the Solanaceae treatment in “Flora Argentina” in 2013 exploration in the country and resolution of outstanding nomenclatural and circumscription issues has resulted in a number of changes to the species of the Morelloid clade of Solanum L. (Solanaceae) for Argentina. Here we describe three new species: Solanum hunzikeri Chiarini & Cantero, sp. nov., from wet high elevation areas in Argentina (Catamarca, Salta and Tucumán) and Bolivia (Chuquisaca and Tarija), S. marmoratum Barboza & S. Knapp, sp. nov., from central Argentina in Catamarca, La Pampa, La Rioja, San Juan and San Luis, and S. tiinae Barboza & S. Knapp, sp. nov., from the mountains of Jujuy, La Rioja, Salta and Tucumán. We provide descriptions, illustrations and distribution maps for all new taxa. A table of nomenclatural changes and additional taxa now known to occur in Argentina summarizes additions and changes since the “Flora Argentina”. We also provide an updated key, including all new taxa for the country, to facilitate identification and further exploration.
Strategies and Business Models of Banks in Front of the FinTech and BigTech Competition
Authors: Kurkliński Lech , Kasiewicz Stanislaw
Published: October 2020

The purpose of the chapter is to evaluate selected strategies and business models as key tools for competing within the financial sector in the digital environment, especially the position of banks against FinTechs and BigTechs, from the perspective of the risk culture factor. The main hypothesis says the success of the process of adapting banks to new competition rules requires the development of individual strategies and business models, taking into account an adequate organizational culture and, within it, a risk culture. To verify this assumption, the relationships between significant competitive features of banks in the digital environment, risk management, and risk culture are presented. The analyses of selected strategies and digital business models are trying to answer the question, to what extent it is possible to implement a new approach, useful in constructing effective solutions for banks to reduce the threats, especially created by FinTechs and BigTechs.

Authors: Sever Mališ Sanja , Žager Lajoš , Brozović Mateja
Published: October 2020

External audit of financial statements plays a key role in achieving transparent financial reporting, since its purpose is to provide reasonable assurance that the presented financial statements are free of material misstatements due to fraud or error. In the process of fulfilling this role, auditors must be adaptable, especially when it comes to technological advancements. This chapter explains the effect that new technologies have on audit of financial statements. In addition to summarizing the technological changes that impacted the audit profession in the past and therefore introduced new generations of audit, the authors have identified issues and challenges in the way the audit is currently performed. Some of the new technologies that are discussed in this chapter have the potential to mitigate these issues. However, new challenges and risks may be introduced with accepting these technologies in the process of financial reporting and auditing.
Detecting Fake News on Social Media
Authors: Bozkanat Esra
Published: October 2020

As Web 2.0 technologies have turned the Internet into an interactive medium, users dominate the field. With the spread of social media, the Internet has become much more user-oriented. In contrast to traditional media, social media's lack of control mechanisms makes the accuracy of spreading news questionable. This brings us to the significance of fact-checking platforms. This study investigates the antecedents of spreading false news in Turkey. The purpose of the study is to determine the features of fake news. For this purpose, teyit.org, the biggest fact-checking platform in Turkey, has been chosen for analysis. The current study shows fake news to be detectable based on four features: Propagation, User Type, Social Media Type, and Formatting. According to the logistic regression analysis, the study's model obtained 86.7% accuracy. The study demonstrates that Facebook increases the likelihood of news being fake compared to Twitter or Instagram. Emoji usage is also statistically significant in terms of increasing the probability of fake news. Unexpectedly, the impact of photos or videos was found statistically insignificant.
Will Social Media and Its Consumption Converge or Diverge Global Consumer Culture?
Authors: Kang Yowei , Yang Kenneth C. C.
Published: October 2020

Social media have been claimed to homogenize human and consumer behaviors around the world – in other words, to make people think, feel, and act alike regardless of national borders. Scholars often debate this claim from either a convergence or a divergence perspective from the marketing and consumer behavior literature. The theoretical foundation will be based on the convergence-divergence debates that postulate universal consumption patterns and values are made possible, due to the industrialization, modernization, technology, and wealth accumulation. The authors use perceptions of online privacy among users of privacy-invasive technologies as an example to discuss why people will think the same about their own privacy could be a myth for the failure to consider the unique socio-cultural characteristics of each nation. This study begins with a global consumption analysis of social media around the world. Then, they examine how privacy concerns may help account for the homogenization or heterogenization trend of global consumer culture. Discussions and implications are provided.
Social Media Consumption Among Kenyans
Authors: Wamuyu Patrick Kanyi
Published: October 2020

Despite the growing popularity of social media among Kenyans, there is limited baseline data on the consumption of these platforms by different Kenyan communities based on demographics such as age, gender, education, income, and geolocation. The study set out to fill this gap through a baseline survey on social media consumption in Kenya. The study used a mixed-method approach, involving a survey of 3,269 respondents and 37 focus group discussions. The social media platforms in use are WhatsApp, Facebook, YouTube, Instagram, LinkedIn, and Snapchat. However, the use of social media differs by demographics. Kenyans use social media for entertainment, education, jobs, politics, sports, and social issues. Most Kenyans access social media using phones for 1-3 hours daily. Motivations for using social media include the acquisition of information, entertainment, and social interactions. Most social media users have experienced fake news, cyberbullying, and bombardment with graphic images of sex and advertisements. Kenyans consider social media to be addictive, expensive, and time-wasting.

Authors: Wamuyu Patrick Kanyi
Published: October 2020

Kenya has a robust blogger community, with hundreds of active bloggers and a variety of stimulating blogs on politics, agriculture, technology, education, fashion, food, entertainment, sports, and travel. The purpose of this chapter was to explore whether Kenyans participate in online discussions and to determine the role of Kenyan bloggers in online communities. Data was collected through a survey of 3,269 respondents aged between 14 and 55 years and social media mining on Twitter using Network Overview, Discovery and Exploration for Excel (NodeXL) API. Survey data was analyzed using descriptive statistics and cross-tabulation while mined data was analyzed for centrality metrics. The study identified Farmers Trend, Ghafla Kenya, KahawaTungu, and Kachwanya as influential blogs in the Kenyan blogosphere and that most Kenyan women read travel and food and fashion blogs while men mostly read sports and politics blogs. This chapter contributes to a better understanding of the Kenyan blogosphere.

Authors: Gupta Sunita , Gupta Sakar
Published: October 2020

IoT technology is used in many areas like the smart wearables, connected devices, automated machines, and driverless cars. However, in agriculture, the IoT has brought the greatest impact. The industrial IoT is a driving force behind increased agricultural production at a lower cost. In the next several years, the use of smart solutions powered by IoT will increase in the agriculture operations. The number of connected devices in agriculture will grow from 13 million in 2014 to 225 million by 2024. The applications of IoT in the agriculture industry have helped the farmers to monitor the water tank levels in real-time, which make the irrigation process more efficient. The advancement of IoT technology in agriculture operations has brought the use of sensors in every step of the farming process like how much time and resources a seed takes to become a fully grown vegetable. Internet of things in agriculture has come up as a second wave of the green revolution.

Effect of Addition of Chromate to Concrete on the Bond Strength of Hot-Dip Galvanized Ribbed Rebar at Ambient Temperature
Authors: Pokorný Petr , Citek David
Published: October 2020

This article studies the effect of chromate (CrO42-) addition to concrete mix on the corrosion behavior of hot-dip galvanized reinforcement and primarily on the bond strength of this reinforcement with concrete. According to the original literature, the addition of chromates should prevent corrosion of the coating in fresh concrete with the evolution of hydrogen. The results show that this is indeed the case, but the need for a greater amount of added chromates also reduces the mechanical properties of the concrete. This ultimately affects the bond strength of the hot-dip galvanized reinforcement with concrete. Due to legislation, it is totally unacceptable to add any amount of chromates to the concrete mix (CrVI - toxic substance).
Experimental Study of the Recycled Plastic Aggregate Lightweight Composites Based on Different Kinds of Binder
Authors: Gregorová Valéria , Štefunková Zuzana , Ledererová Miriam
Published: October 2020

In this paper, the selected properties of lightweight composites based on the different kinds of binder and recycled waste plastics aggregate were studied. Plastic waste e.g. foamed polystyrene, polypropylene, polyurethane foam or ethyl vinyl acetate (EVA) as an aggregate in these composites was used. Cement CEM II B/S 32.5 R and an organic-based adhesive with the business name Conipur 360 were used as a binder. The cement composites consisted of constant water to cement ratio 0.50 and dose of cement 175 kg/m3. Mixtures of adhesive composites were prepared with constant dose of adhesive 100 kg/m3. The kind of recycled waste aggregate was only changed. The physical properties, such as bulk density, compressive strength and thermo-technical properties were verified. The application of organic-based adhesive resulted in a significant decreasing values of the bulk density (100 kg/m3 - 230 kg/m3) and the thermal conductivity coefficient (0.0511 W/m.K - 0.0686 W/m.K) of lightweight composites. The negative impact of this type of binder resulted to a decreasing value of the compressive strength (0.15 MPa - 0.32 MPa). Use of cement binder caused to an increasing of bulk density (290 kg/m3 - 375 kg/m3) and worsening of the thermal conductivity coefficient of these composites (0.0660 W/m.K - 0.0799 W/m.K). The compressive strength values of cement composites ranged from 0.24 MPa to 0.50 MPa.
Macroscopic loops in the loop $O(n)$ model at Nienhuis' critical point
Authors: Duminil-Copin Hugo , Glazman Alexander , Peled Ron , Spinka Yinon
Published: October 2020

The loop

O(n)

model is a model for a random collection of non-intersecting loops on the hexagonal lattice, which is believed to be in the same universality class as the spin

O(n)

model. It has been predicted by Nienhuis that for

0\le n\le 2

, the loop

O(n)

model exhibits a phase transition at a critical parameter

x_c(n)=1/\sqrt{2+\sqrt{2-n}}

. For

0 < n \le 2

, the transition line has been further conjectured to separate a regime with short loops when

x < x_c(n)

from a regime with macroscopic loops when

x\ge x_c(n)

.

In this paper, we prove that for

n\in [1,2]

and

x=x_c(n)

, the loop

O(n)

model exhibits macroscopic loops. Apart from the case

n = 1

, this constitutes the first regime of parameters for which macroscopic loops have been rigorously established. A main tool in the proof is a new positive association (FKG) property shown to hold when

n \ge 1

and

0 < x \le\frac{1}{\sqrt{n}}

. This property implies, using techniques recently developed for the random-cluster model, the following dichotomy: either long loops are exponentially unlikely or the origin is surrounded by loops at any scale (boxcrossing property). We develop a “domain gluing” technique which allows us to employ Smirnov’s parafermionic observable to rule out the first alternative when

n\in[1,2]

and

x=x_c(n)

.
Symmetries of slice monogenic functions
Authors: Colombo Fabrizio , Kraußhar Rolf Sören , Sabadini Irene
Published: October 2020

In this paper we consider the symmetry behavior of slice monogenic functions under Möbius transformations. We describe the group under which slice monogenic functions are taken into slice monogenic functions. We prove a transformation formula for composing slice monogenic functions with Möbius transformations and describe their conformal invariance. Finally, we explain two construction methods to obtain automorphic forms in the framework of this function class. We round off by presenting a precise algebraic characterization of the subset of slice monogenic linear fractional transformations within the set of general Möbius transformations.
An Algorithm of Tracking and Controlling Network Attack Node based on Adaptive Neural Networks
Authors: Wang Wei
Published: October 2020

In order to obtain certain and comprehensive information for formulating network attack strategy, a complex network attack method is proposed in this paper. The attackers’ income, loss, cost and encountered risk in network attack are analyzed and index system is established to evaluate attack effect of network node with dynamic Bayesian network. This method can overcome defects of static evaluation which is relied on single index of network topology. Simulation experiment shows that this method combines more nodes and observation during the attack. It can avoid the gap between actual attack effect and theoretical expectation when attack is implemented by relying on static evaluation. In the meanwhile, it is more accurate in attack precision and of high attack efficiency

O “objeto” livro não se desintegrou – ao menos completamente – nas nuvens da informação. Coabitando com diferentes tecnologias, mas sobretudo com temporalidades e usos distintos, as páginas impressas seguem seu rumo, por vezes em formato digital, no intuito de tentar dizer o seu próprio tempo. Aproveitamos a metáfora religiosa do professor Miguel Pereira: nesse contexto de mudanças de suporte, segundo ele, o decisivo é atentar para a construção de sentidos,já que, em última instância, “a palavra é santa”. De maneira análoga, Jacques Rancière costuma afirmar, em postura filosófica, que não analisa senão imagens em suas conjugações entre regimes de aparecer e obras particulares.

A maioria dos museus pelo mundo afora possui lojas que oferecem mercadorias associadas ao que está exposto ou a algum artista específico. O foco de interesse deste artigo é o estudo do campo do Design através do consumo dos objetos associados ao filme O Mágico de Oz que são vendidos nas lojas localizadas no National Museum of American History. Nosso objetivo é compreender tal consumo com base na noção de habitus abordada por Pierre Bourdieu.

THE SUGAR CANE ROOT CATERPILLAR AND OTHER NEW ROOT PESTS IN PUERTO RICO
Authors: Seín, Jr. Francisco
Published: October 2020

1. A root-boring caterpillar has been found in Puerto Rico in the soil around sugar cane roots which has been named the sugar cane root caterpillar, Perforadix sacchari new genus and species (Pyralididae, Endotrichinae). It had been previously reported as Sufetula grumalis Schaus (Pyralididae, Pyraustinae) and specimens under that name from Puerto Rico and Santo Domingo are to be found in the collection of the U. S. National Museum in Washington. 2. In captivity, the larvae will also feed on the roots of corn, bamboo and Gynerium sagitattum, but in nature no indication of the work of this insect has been found on the roots of these plants. 3. In the early instars the caterpillars feed on the very tender roots or in their absence may tunnel in the cortex of the mature roots of sugar cane. The later instar caterpillars tunnel in the thick succulent tips of the tender roots. 4. The damage is cumulative. As the plantation grows older the number of caterpillars and the amount of injury increases. The injury may not show above ground but probably it causes always some reduction in yield and shortens the duration of the plantation. Upon the advent of dry weather and when the soil conditions are unfavorable for the production of new roots, the destruction of the root-tips may become in some localities the limiting factor in sugar cane growing. 5. The distribution of the caterpillars is not uniform in any plantation, and furthermore they seem to migrate from one plant to another in search of fresh root tips. As the soil also varies within any particular field, the root injury showing in the parts of the plant above ground, is not uniform. Scattered stools or patches of stools will dry out while the rest of the plantation may be uniformly green. 6. As a rule, when the soil conditions are proper for the sugar cane plant, although the injury to the roots may be abundant, it does not show above ground. 7. The root injuries produced by the younger caterpillars may he confused with those produced by other soil animals, but the tunneling in the larger roots made by the older caterpillars and the piles of whitish excrement thrown out of them are characteristic and unmistakable. 8. Soil fumigants have so far proved impractical, but the cultural practices recommended by Earle for "root disease" would make it possible for the plants to keep up a constant production of new roots and to produce satisfactory yields in spite of the injury caused by the root caterpillar. 9. Other new root pests of sugar cane whose injuries are found associated with those of the root caterpillar are the Symphylid, Hanseniella sp., the bristle-tails, Nicoletia and Lepisma spp., and the sow bug, Philoscia culebrae Moore.

Gediz Vadisinde Erken Pleistosen Dönemi Sualtı Volkanizması: Kavtepe - Kula Volkanik Yöresi
Authors: AYTAÇ Ahmet Serdar , DEMİR Tuncer
Published: October 2020

Dünya üzerinde volkanizmanın oldukça önemli bir kısmı okyanus diplerinde meydana gelmesine rağmen sualtı volkanizma araştırmaları oldukça sınırlı kalmıştır. Bununla birlikte özellikle son dönemlerde deniz dibi jeomorfolojisi ile ilgili araştırmalarda önemli gelişmeler kaydedilmesi bu gizemli alanın önceden tahmin edilemeyen özelliklerinin de belirlenmesine yardımcı olmuştur. Gerçekten de bugün için okyanus ortası sırtlarında bulunan volkanların yeryüzündeki volkanların yaklaşık olarak %75 ini oluşturduğu bilinmektedir. Hernekadar su altı volkanlarının önemli bir kısmı derin deniz ve okyanus tabanların yer alsalar da bunların bazıları ise sığ deniz alanları ile göl ortamlarında da yer almaktadırlar. Dünya üzerinde karasal volkanizmanın oluşum süreçleri, ürünleri ve ortaya çıkan şekiller çok iyi bilinmesine rağmen denizaltı veya sualtı volkanizmasına ilişkin bilgilerimiz oldukça yenidir. Bu durumun temel nedeni sualtı volkanizmasına ilişkin birçok sürecin kolaylıkla gözlemlenememesidir. Yakın bir zamana kadar, sualtı volkanizmasına ilişkin bilgilerimizin önemli bir kısmı geçmiş volkanizmaların izleri üzerine yorumlama ile elde edilmektedir. Bu yönüyle Kula yöresi gerek karasal volkanizma gerekse sınırlı bir alanda gerçeklemiş olsa bile su altı volkanizması açısından yer tarihinin önemli delillerini barındırmaktadır. Bu çalışmada Erken Pleistosen döneminde Kula’da paleo-Gediz nehri üzerinde oluşan lav seti gölü (paleo-göl) içerisinde meydana gelen su altı volkanizması ve buna bağlı oluşan volkanik şekillerin oluşumunun jeomorfolojik delillerinin ortaya konulması amaçlanmıştır. Araştırmada uzun yıllardan beri yörede yürütülmekte olan projelerimizin arazi bulgularından yararlanılmıştır. Çeşitli stratigrafik birimlerin yaş bilgileri ise söz konusu projelerin yaşlandırma analizlerinden veya alana ilişkin literatürden temin edilmiştir. Araştırma kapsamında Kavtepe’nin yörede yaygın görülen Miyosen yaşlı sedimanter birimleri kesip çıkan bir volkanik çıkış merkezi, volkan bacası olduğu; Kavtepe volkanizmasının iki evrede gerçekleştiği, başlangıçta volkanizmanın Paleo-Gediz vadisine yakın bir yerde başladığı ve açığa çıkan lavların Paleo-Gediz’in VI. taraçasını kısmen örttüğü belirlenmiştir. Volkanizmanın ikinci evresinin ise Akçeme volkanının Gediz Nehrini bloke ettikten sonra oluşan paleogöl içerisinde gerçekleştiği ve ikinci evrede açığa çıkan lavların, doğrudan su ile temas ederek yastık lava dönüştüğü tespit edilmiştir.
The Role of Literary Instruction in the Development of Reading and Writing Skills in Spanish as a Heritage Language during Childhood
Authors: Cuza Alejandro , Miller Lauren , Pasquarella Adrian , Chen Xi
Published: October 2020

The present study examines the role of instruction in the development of reading and writing skills in Spanish as a heritage language during childhood. Sixty-six (n=66) Spanish heritage speakers in K-4th grade participated in an 18-week Spanish intervention. The curriculum included the development of phonological awareness, reading fluency and accuracy as well as vocabulary via cognate instruction. Undergraduate students majoring in Spanish conducted the intervention as part of a service-learning program. Standardized measures given to the students before and after the intervention included phonological awareness, receptive vocabulary knowledge, word reading accuracy, and word reading fluency. The treatment group was compared to a group of twenty-five children (n=25) who did not participate in the program. The two groups were matched by age and non-verbal reasoning. Results from pre and post-tests showed significant gains for the treatment group in vocabulary growth, word reading fluency and word reading accuracy. Phonological awareness developed significantly for both groups, but there was no advantage for the experimental group. Overall, the intervention was effective at
promoting both Spanish language and literacy skills (Rhoades, 2009). Contextualized and
explicit instruction on word reading and decoding, as well as oral language and vocabulary
knowledge in Spanish, helped Spanish heritage learners develop academic language and literacy skills in their first/minority language. Furthermore, the results provide strong evidence supporting the efficacy of a service-learning program aimed at facilitating the development of literacy skills among child heritage language learners.

Abstract

Objective: To determine the effects of core stability exercises on backache and quality of life of postmenopausal women.

Method: The comparative study was conducted at the Department of Physical Therapy, Margalla General Hospital, Rawalpindi, Pakistan, from February to June 2018, and comprised post-menopausal woman aged 40-60 years having backache who were randomly divided into experimental group A and control group B. Group A underwent core stability exercises along with traditional therapy, while group B had traditional low backache physical therapy. Each participant was treated three days a week for 12 weeks. The outcome was assessed using the manual muscle testing numerical pain rating scale, Oswestry disability index and Utian quality of life scale at baseline, week 6 and week 12. Data was analysed using SPSS 21.

Results: Of the 35 subjects initially enrolled, 24(68.5%) completed the study. Of them, 14(58.3%) cases were in group A and 10(41.6%) controls in group B. The overall mean age was 54.54±5.13 years, mean menopause duration was 99.79±50.02 months, and mean duration of backache complaint was 23.95±14.85 months. Differences in outcome were significant between the groups for flexion and extension manual muscle testing and Utian quality of life scale (p<0.05) and non-significant for numerical pain rating scaleand Oswestry disability index (p>0.05). 

Conclusion: Core stability exercises were found to have the ability to reduce pain, disabilitym and to improve strength and quality of life.

Key Words: Backache, Core stability exercises, Post-menopause, Oswestry disability index, Utian Quality of life.
