"Il palpitare lontano di scaglie di mare"
Authors: Isenburg Teresa
Published: June 2021

Nel corso della seconda metÀ dell'ottocento la frangia costiera e il suo immediato entroterra, spesso costituito da zone umide, ha subito una drastica modificazione grazie all'utilizzo delle tecnologie rese possibili dalla forza della macchina a vapore: č questa un'ulteriore conferma dello scarso legame con l'universo marino della formazione culturale e dell'agire operativo dell'Italia contemporanea.
Dualismi e identitÀ nella storia del mare italiano
Authors: Maifreda Germano
Published: June 2021

Il volume di Frascani ripropone implicitamente la questione di fondo del dualismo economico, culturale e sociale che ha contraddistinto la storia italiana degli ultimi secoli. Lette attraverso la lente di ingrandimento della storia marina, l'evoluzione produttiva e la costruzione simbolica nazionale presentano, una volta di piů, la fisionomia ambigua e differenziata. Le dinamiche del potere e la sua carica disciplinante vengono analizzate con acume e profonditÀ, sollecitando nuovi interrogativi e gettando una luce talvolta inquietante su un tema che, da sempre, la retorica da Belpaese ha piuttosto presentato come unificante e pacificatore.
La conquista del mare e la modernitÀ
Authors: Zanetto Gabriele
Published: June 2021

L'appropriazione del mare da parte della cultura e l'economia nazionali italiane ha comportato la destrutturazione di un rodato rapporto col mare da parte delle culture lo- cali e regionali. Il caso di Venezia suggerisce che queste potevano essere recuperate pur in un contesto a diversa scala geografica.
Sperimentazioni progettuali per piattaforme complesse: spunti per una discussione
Authors: Rolando Andrea
Published: June 2021

- Complex platforms raise a number of issues, concerning above all problems related to urban and regional planning. These are dealt with in the framework of disciplines that tend more and more to focus on the management of regulative and procedural processes to the detriment of traditional planning practices that place greater emphasis on architectural, urban and landscape design. Hence in order to understand the role that ‘megastructures' take on in the composition of contemporary landscapes, more attention needs to be paid to the design side of things and to the development of innovative skills and know-how. In this regard, the increasingly close interaction between what has traditionally been considered ‘free time' and time given over to shopping (an activity carried out in artificial places situated outside city centres but in areas of landscape interest) is proof solid of how it has now become indispensable to initiate a virtuous process that will reconcile functional needs with higher standards of spatial and environmental quality.
Towards an interstitial approach to urban landscape
Authors: Lévesque Luc
Published: June 2021

- The history of western landscape can be conceived as the conquering of ‘non-places', by which is meant above all unknown lands with a reputation of being ‘horrendous' or uninhabitable, that are gradually brought under control, assigned a cultural value and subsequently transformed into ‘places' and landscapes. These are generic spaces without any clear history or identity. Airports, intersections and shopping centres, as well as the residual spaces associated with these, are just some examples of environments that Augé refers to as ‘non-places'. In order to breach this impasse, it becomes necessary to relinquish a privileged relationship that links one's living environment with an image of protection, the latter being associated in turn with archetypical places. By the same token, one must resist the temptation to classify an area as a ‘place' or ‘non-place' without prior examination or analysis. Various methods capable of altering our perception of urban areas can be used to set this process in motion.
Poli della regione urbana milanese verso l'Expo 2015
Authors: Bianchi Alessandro
Published: June 2021

- Can we today use symbolism to govern a city whose localities can no longer be distinguished? The city has become polycentric and needs symbols to make its decentred landmarks recognisable once again. Zoning was completed some time ago (at least on paper, and certainly not in the minds of local and national administrators), but it is still not altogether clear what is meant by upgrading of the run-down suburbs. Are these notions that await concretisation in laws from which quality architecture will then flow? Or, rather, should the plan go back to being informed primarily by a design which has yet to be regulated by law? These days it seems like community services are redesigning the city in the likeness of a printed circuit board. Indeed, development of the entire area is fuelled by responses to demands for better transport, communications, goods, housing, jobs and leisure facilities, or at least this is how it appears to those who believe in this contemporary paradigm. However, men and women do not identify with public services. They simply use them. Let us therefore avoid the temptation to turn a means into an end.
Pianificazione strategica e prospettiva repubblicana
Authors: Mazza Luigi
Published: June 2021

- In order for it to be complete, a planning system cannot be limited to local considerations. A higher level of conceptualisation is required, though very often this is lacking or else is present only formally, hence without any tangible consequences. In the debate of the last few decades, commentators have reached consensus over the fact that strategic planning should be seen not only as being on a higher level than local planning, but above all as a different way of planning. The present article explores the discontent that for several years has been a constant companion of this type of planning and traces the reasons for this in three main issues, all of which boil down to excessive expectations in strategic plans. The piece concludes by arguing that it is possible to design and implement a complete planning system only in a republican perspective, by which is meant using a spirit of ‘constitutional patriotism' as the foundation on which to rebuild an authoritative role for the state in the context of legality accompanied by a renewed sense of responsibility vis-à-vis planning.
Per rotte poco battute. 40 anni di avventure educative in giro per il mondo
Authors: Ceccarelli Paolo
Published: June 2021

The author looks back over the stages and subjects of long years of teaching and organisation in numerous international workshops on planning, bringing young people to address emerging problems not covered by the rulebook and encouraging them to get off the beaten track. It is a commitment conducted in the conviction that there is no sense in remaining closed within the ivory tower and that the search for new answers to old and new problems does not produce any serious results if it is conducted by introspective academics or fashionable professionals. We need to know ourselves better and influence each other reciprocally, with modesty and perseverance, working together on population groups who have specific problems to solve.
The selection of anthropogenic habitat by wildlife as an ecological consequence of rural exodus: empirical examples from Spain
Authors: Martínez-Abraín A. , Ferrer X. , Jiménez J. , Fernández-Calvo I. C.
Published: June 2021

The increasing urbanization of the landscape is a major component of global change worldwide. However, it is puzzling that wildlife is selecting anthropogenic habitats despite the availability of apparently high–quality semi–natural (i.e. less intensively modified) habitats. Definitive explanations for this process are still lacking. We have previously suggested that colonization of the urban habitat is initially triggered by ecological processes that take place outside urban areas as a consequence of past rural exodus. Here we present a diverse array of examples of selection of several types of anthropogenic habitat by wildlife in Spain (including transportation infrastructure, human–exclusion areas, urban areas under construction, cities, reservoirs, quarries and landfills) in support of this idea. Wildlife is moving out of its historical ecological refuges and losing fear of harmless urban humans. Mesopredators are rebounding by mesopredator release, due to ceased human persecution, and shrubs and trees are claiming former agricultural habitats. Together, these factors force many species to move to urbanized areas where they find open habitats, food associated with these habitats, and protection against predation. Hence, the classical balance of costs and benefits that takes place once inside urban areas, would actually be a second step of the process of colonization of urban areas. A better understanding of the initial triggers of urban colonization could help us increase the biological value of human–made habitats for wildlife in the future.
A Study Between the Taxpayers’ Perception Toward the Tax Policy Changes and the Tax Compliance in Sri Lanka: A Tax Relief in Response to the Impact of Covid-19 Epidemic, and its Implications
Authors: Gamini Bandara K. G. Asela , Weerasooriya W. M. R. B.
Published: June 2021

Purpose – This paper primarily investigates the relationship between the taxpayers’ perception of the tax policy changes and the tax compliance in Sri Lanka. The researcher also aims to provide advice to the policymakers about the specific approach to be followed when considering the tax relief measures and also emphasizing the importance of maintaining a flexible tax policy during the epidemic period which will be crucial in meeting the revenue target of the government. Design/Methodology/approach-The researcher used questionnaires to gather primary data from 125 respondents and then editing to spot errors and omissions for the aim of creating necessary corrections and at last, apply statistical tools for data analysis using SPSS software. Findings – The results show that taxpayers’ attitudes toward the changes in the tax policy and tax compliance form a strong positive relationship and further, changes in its policy have a significant impact on their compliance level. Cronbach’s alpha exceeds 0.7 implies that instruments are sufficiently reliable for the measurement. Originality/value- This was the first study undertaken to explore the link between the attitude toward the tax policy changes and the tax compliance in Sri Lanka during the Covid-19 epidemic period. This study guides to fill up the existing research gap in the country and further, directions are also useful for future researchers to undertake an identical survey.
Implications of Illicit Financial Flows on Zimbabwe's Development
Authors: Kurebwa Jeffrey
Published: June 2021

Illicit Financial Flows (IFFs) is a major challenge to Zimbabwe's development. They have a direct impact on the country’s stability to raise, retain and mobilize its own resources to finance sustainable economic development. The study finds that Zimbabwe lost over US$32.179 billion during the period 2000 to 2020. The study relies on normative and legal arguments to justify the effects of illicit financial flows. The problems with IFFs are that they are not only illicit but that their effect spreads far beyond their immediate area of occurrence. Zimbabwe has suffered irreparable damage because of illicit financial flows. IFFs are mainly driven by the desire to hide wealth and to evade taxes; perpetrators clearly do not respect the obligations of citizenship. Financial flows are crucial for poor countries and have played an important role in Zimbabwe. Since not all financial flows are good for development, the integration of poor countries into the global financial system poses opportunities as well as risks.

Published: June 2021

Textbooks used in schools affect the quality of mathematics learning in the country. Indonesian Ministry of Education (Kemendikbud) already lauched students’ and teachers’ textbook that are distributed nationally on 2013; however improvements are needed to revise the textbooks since there are concerns such as the difficulty level of problems contained in the textbooks. The main objective of this study is to compare non-routine problems contained in mathematics textbooks used in Indonesia and Singapore. This is a qualitative research with content analysis design. Researchers compare Singaporean and Indonesian mathematics textbook since Singapore got higher rank in mathematics based on PISA result in 2018. The topic in this study is limited to Pythagorean Theorem. The result of the research shows that Indonesia and Singapore has consecutively 22,1% and 11,3% non-routine problem. Another finding of this study was Singaporean mathematics textbook focused more on developing students’ fluency of solving problems, meanwhile Indonesian mathematics textbook focused more on students’ reasoning ability. The results and findings in this paper are expected to provide input in developing future mathematics textbooks.

Bu çalışma, enflasyona ve vergiye göre ayarlanmış emeklilikte para çekme oranlarının ana sermayeye etkilerini göstermektedir. Yatırımcının ana parasını kaybetmeden portföyünden ne kadarını çekebileceği emeklilik kararı almasında önemli bir faktördür. %50 hisse senedinden ve %50 devlet tahvillinden oluşan portföyde 2005-2019 yılları arasında Türkiye’de güvenilir çekme oranı %4 olarak bulunmuştur. Bengen %4 kuralının Türk finans piyasası içinde geçerli olduğu görülmektedir. %3 oranında çektiğinde portföyde para birikmeye devam etmekte, %5 oranında çektiğinde portföyde para azalmaktadır. Hisse senedi ağırlığını arttırmak daha yüksek çekme oranına izin vermekteyse de, risk yükselmektedir. Devlet iç borç senetleri getirilerinin borsanın düştüğü zamanda yükselmesi, portföye istikrar getirmektedir. Türkiye’deki yatırımcılarının tercih ettiği mevduat getirisine göre %4 çekme oranında portföy %23’lük değer kaybetmektedir.

Indian power management system is one
among the largest power system networks in the world.
India has a complex power transmission network which is
monitored by multi-level integrated systems installed at
many control levels. The Indian power sector is expected
to grow both in its installed capacity and energy demand
which makes it extremely essential to equip the country’s
power grid with novel applications of smart grid
technologies. A technologically advanced architecture of
power system could be beneficial to address issues at micro
level and improve flexibility and robustness of the system.
This research highlights technical advancements which are
in practice in different countries. A conceptual design
framework has been proposed which can be integrated
with the existing energy management system and thus
could potentially help in an improvised efficient
monitoring and control system. Thus, help resolve chances
of cascaded outages leading to blackouts.

Prochilodus nigricans (Osteichthyes: Prochilodontidae) es un pez muy conocido en la Amazonía Peruana como “Boquichico”, de tamaño mediano y carne agradable, su consumo es tradicional y básico para la alimentación de la población; sin embargo, existen algunos factores socioeconómicos que permiten que las personas puedan consumir o no. El objetivo es determinar los factores que determinan el consumo en la ciudad de Pucallpa, que corresponde a un trabajo explicativo de corte transversal. Se realizó 385 encuestas. El análisis de los datos se realizó a través de la estimación de un modelo logit (regresión logística). Los resultados muestran que, de los siete factores considerados como el nivel de ingreso, edad, género, nivel de educación, carga familiar, ocupación e idioma, solo el ingreso familiar (P-value = 0.000) y el nivel de educación (P-value = 0.049) determinan el consumo de Prochilodus nigricans (Boquichico). Se concluye, que si el encuestado incrementa en un sol (S/. 1.00) su nivel de ingreso, el consumo de este pescado disminuye en un 3.8%, al igual que si su nivel de educación asciende en un nivel el consumo disminuirá en un 7.3%.
Sustainable development and
environmental problem
Authors: Malakar Bharat
Published: June 2021

Different forms of inequality, resulting from anthropogenic environmental changes, constitute a large part of the environmental problems. Environmental benefits and harms are not distributed equally across and within national boundaries. Such benefits and harms are unevenly distributed within and between generations. The environmental harms are caused by our current practices and will afflict our future generations, while benefits are enjoyed by the present generations alone. The concepts of “sustainability” and “sustainable development” have been developed to address such problems of inter-generational equality. The concept of sustainability began its career in the context of sustainable agriculture and sustainable ecological system. Any account of sustainability must answer questions about what should be sustained, for whom it is to be sustained and why. In the mainstream economic literature, the answer to the first questions is a certain level of human welfare which is understood as preference satisfaction. This definition leads to the further questions as to what is required for such maintenance of this level of human welfare over time. The main aim of this article is to discuss these entire problems and provide some
possible solutions to overcome this challenge positively.
Centrality Measures in Residue Interaction Networks to Highlight Amino Acids in Protein–Protein Binding
Authors: Brysbaert Guillaume , Lensink Marc F.
Published: June 2021

Residue interaction networks (RINs) describe a protein structure as a network of interacting residues. Central nodes in these networks, identified by centrality analyses, highlight those residues that play a role in the structure and function of the protein. However, little is known about the capability of such analyses to identify residues involved in the formation of macromolecular complexes. Here, we performed six different centrality measures on the RINs generated from the complexes of the SKEMPI 2 database of changes in protein–protein binding upon mutation in order to evaluate the capability of each of these measures to identify major binding residues. The analyses were performed with and without the crystallographic water molecules, in addition to the protein residues. We also investigated the use of a weight factor based on the inter-residue distances to improve the detection of these residues. We show that for the identification of major binding residues, closeness, degree, and PageRank result in good precision, whereas betweenness, eigenvector, and residue centrality analyses give a higher sensitivity. Including water in the analysis improves the sensitivity of all measures without losing precision. Applying weights only slightly raises the sensitivity of eigenvector centrality analysis. We finally show that a combination of multiple centrality analyses is the optimal approach to identify residues that play a role in protein–protein interaction.
Integration of Engineered “Spark-Cell” Spheroids for Optical Pacing of Cardiac Tissue

Published: June 2021

Optogenetic methods for pacing of cardiac tissue can be realized by direct genetic modification of the cardiomyocytes to express light-sensitive actuators, such as channelrhodopsin-2, ChR2, or by introduction of light-sensitized non-myocytes that couple to the cardiac cells and yield responsiveness to optical pacing. In this study, we engineer three-dimensional “spark cells” spheroids, composed of ChR2-expressing human embryonic kidney cells (from 100 to 100,000 cells per spheroid), and characterize their morphology as function of cell density and time. These “spark-cell” spheroids are then deployed to demonstrate site-specific optical pacing of human stem-cell-derived cardiomyocytes (hiPSC-CMs) in 96-well format using non-localized light application and all-optical electrophysiology with voltage and calcium small-molecule dyes or genetically encoded sensors. We show that the spheroids can be handled using liquid pipetting and can confer optical responsiveness of cardiac tissue earlier than direct viral or liposomal genetic modification of the cardiomyocytes, with 24% providing reliable stimulation of the iPSC-CMs within 6 h and >80% within 24 h. Moreover, our data show that the spheroids can be frozen in liquid nitrogen for long-term storage and transportation, after which they can be deployed as a reagent on site for optical cardiac pacing. In all cases, optical stimulation was achieved at relatively low light levels (<0.15 mW/mm2) when 5 ms or longer pulses were used. Our results demonstrate a scalable, cost-effective method with a cryopreservable reagent to achieve contactless optical stimulation of cardiac cell constructs without genetically modifying the myocytes, that can be integrated in a robotics-amenable workflow for high-throughput drug testing.

Cyclin Y (CCNY) is a novel cyclin and highly conserved in metazoan species. Previous studies from our and other laboratory indicate that CCNY play a crucial role in tumor progression. There are two CCNY isoform which has different subcellular distributions, with cytoplasmic isoform (CCNYc) and membrane distribution isoform (CCNYm). However, the expression and function of CCNY isoforms is still unclear. We firstly found CCNYc was expressed in natural lung cancer tissue and cells through the subcellular distribution. Co-IP and immunofluorescence showed that both CCNYm and CCNYc could interact with PFTK1. Further studies illustrated that CCNYc but not CCNYm enhanced cell migration and invasion activity bothin vivoand vitro. The function of CCNYc could be inhibited by suppression of PFTK1 expression. In addition, our data indicated that tropomyosin 4 (TPM4), a kind of actin-binding proteins, was down-regulated by suppression of CCNY. F-actin assembly could be controlled by CCNYc as well as PFTK1 and TPM4. As a result, CCNY was mainly expressed in lung cancer. CCNYc could promote cell motility and invasion. It indicated that CCNYc/PFTK1 complex could promote cell metastasis by regulating the formation of F-actin via TPM4.

Stable HBEA zeolite with high surface area and strong acid sites was synthesized from coal fly ash–based silica extract via indirect hydrothermal synthesis. The rapid HBEA hydrothermal crystallization times of 8, 10, and 12 h were achieved through a reduced molar water fraction in the synthesis composition. The HBEA zeolites prepared from fly ash silica extract exhibited well-defined spheroidal-shaped crystal morphology with uniform particle sizes of 192, 190, or 239 nm obtained after 8, 10, or 12 h of synthesis time, respectively. The high surface area and the microporous area of 702 and 722 m2/g were achieved as a function of shorter hydrothermal synthesis durations (10 and 24 h, respectively) compared to 48 or 72 h, which resulted in HBEA zeolites with lower surface areas of 538 and 670 m2/g. Likewise, temperature-programmed desorption measurements of fly ash–based HBEA zeolites revealed the presence of weak and strong acid sites in the zeolite. The submicron crystal sizes with a well-defined porosity of HBEA zeolites enhanced the diffusion of anisole and benzoyl chloride molecules toward the active acid sites and hence showed better conversion and selectivity in acylation products. High conversion of benzoyl chloride with anisole was achieved, reaching up to 83% with a 93–96% selectivity toward 4-methoxyacetophenone.

Published: June 2021

Immune cells can optimize the management of metabolic resources to balance their energy requirements in order to regulate immune responses. The interconnection between immunometabolism and fungal infections is becoming increasingly apparent. Using proteome and metabolome assays, we found that stimulation of primary human monocytes by Candida albicans was accompanied by upregulation of glucose transporter 3 (GLUT3) and activation of the glycerophospholipid metabolism pathway. Upregulated GLUT3 expression has been preliminarily confirmed in monocytes from patients with C. albicans bloodstream infection. Our findings support the importance of GLUT3 in the complex network of glycerophospholipid metabolism and the innate immune responses against C. albicans. In summary, this study might contribute to decipher the regulatory mechanism between the monocyte metabolic reprogramming and innate immune response and reveal potential targets for the antifungal treatments.
