Aritmética, paradigmas o gramática: el anunciado desconcierto de los urbanistas
Authors: Quero-Castanys Damián
Published: May 2022

Durante la última década la urbanística ha perdido pausadamente la capacidad de intervención en las ciudades. Quienes han sustentado hasta ahora el pensamiento y la docencia, y actualizado la teorización y la práctica, manifiestan su alarma por la ruptura disciplinar y la disolución del pensamiento. Esta aportación se hace cuando es ya evidente el riesgo de cancelación de la urbanística, pero todavía mantenemos la ilusión de su regeneración. Lo que se ha dado en llamar el nuevo paradigma aplica la ecología en sustitución de la sociología; la biología en lugar de la antropología, y un concepto ambiguo de naturaleza sustituye a la geografía. Este pensamiento positivista del territorio es ajeno al estado actual de las ciencias y no conocemos la estructura lógica de sus conceptos. Este documento propone una regeneración que recupere el hilo perdido de la urbanística, que reúna investigación y proyecto, renueve el léxico y la sintaxis aplicando las nociones actuales de estructura, de materia y tiempo: hacer de la ciudad objeto científico de la urbanística.
La poliurbanidad: estrategias para aportar centralidad a los territorios con precariedad urbana
Authors: Cervera-Alonso de Medina Marina , Llop-Torné Carlos , Peremiquel-Lluch Francesc
Published: May 2022

Un nuevo concepto, la “poliurbanidad”, abre la posibilidad de atributos y cualidades nuevas para los territorios precarios de las metrópolis contemporáneas. Tomando en consideración ineludible los derechos de la ciudadanía que habita barrios periféricos y territorios periurbanos, se proponen estrategias para mejorar la habitabilidad, a través de nuevas centralidades y acceso alternativo a los servicios esenciales. Las tres estrategias son: la inserción de nuevos espacios de centralidad en áreas vulnerables, mediante la adecuación de los espacios intersticiales entre tejidos precarios, la reconversión de las barreras de las infraestructuras y la implementación de hiper lugares móviles. El texto concluye con la necesidad de atención a lo especifico, frente a soluciones homogeneizadoras, y la poliurbanidad como recurso para alcanzar los objetivos de desarrollo sostenible.

Published: May 2022

Los barrios constituyen una unidad adecuada para afrontar y resolver, desde la escala arquitectónica, urbana y humana algunos de los problemas de eficiencia, calidad ambiental, cohesión social y sostenibilidad que preocupan en la actualidad a las entidades públicas y a la ciudadanía. Por su parte, las dos terceras partes de la población que habita hoy en las ciudades españolas, lo hace en áreas de periferias consolidadas, es por ello que parece prioritario centrar la atención en estos entornos urbanos. El artículo tiene como objetivo plantear un método de análisis, con el barrio como unidad básica, que pueda servir de aplicación en operaciones de regeneración urbana atendiendo a los Objetivos de Desarrollo Sostenible. Para ello, se presenta un estudio del barrio Soternes en el distrito 7 de la ciudad de Valencia, generado a raíz del crecimiento por extensión de la ciudad en la segunda mitad del s. XX.
Morfología de los paisajes tradicionales en la España interior: potencialidad de lo rural construido para un futuro más sostenible
Authors: De las Rivas-Sanz Juan Luis , Castrillo-Romón María A. , Fernández-Maroto Miguel , Jiménez-Jiménez Marina
Published: May 2022

La demanda de una nueva cultura del territorio enfrenta el proyecto sostenible con los interrogantes de un medio rural abandonado, sobre todo en los paisajes menores de la España interior, donde las relaciones entre “campo” y “ciudad” deberían ser regeneradas. ¿En qué medida la forma de los paisajes tradicionales del medio rural es un activo de futuro? Superando tanto la idea de sostenibilidad asociada a un entorno sin desarrollo, de refugio en retroceso, como la visión patrimonial de un campo sin dolor, emerge una lectura “activa” del territorio dirigida a repensar desde dentro espacios muy antropizados, aunque en declive. Es aquí donde una serie de proyectos realizados o en curso por nuestro grupo de investigación desarrollan desde el paisaje una herramienta de conocimiento operativo y detectan en la morfología de lo construido en los espacios rurales un potencial no sometido exclusivamente a los intereses del turismo o la segunda residencia, de urbanitas en descanso, sino abierto a un proyecto global de hábitat más sostenible.

Hierarchical approach divides the problems into several stages according to product type and product family, and provides problem solving much more easily. This study introduces a comparative analysis for disaggregation types of two research papers which utilize hierarchical production planning models in supply chain processes.
Alternative Representations of Some Arithmetic Functions
Authors: Cardei Petru
Published: May 2022

This article presents some results of the attempt to simplify the writing of arithmetic functions on the computer so that users can apply them without additional operations, such as summing after a set whose elements must be calculated, such as the set of numbers prime. The important role of the remainder function in defining most arithmetic functions is highlighted. Defining algorithms for the prime factorization of natural numbers highlights the possibility of representing natural numbers in a basis as "natural" as possible for natural numbers, namely the basis of prime numbers. The disadvantage of this natural basis is, for the time being, that it is infinitely dimensional. For now, this representation provides advantages but also disadvantages. Among the arithmetic functions proposed in the article, there are also statistical characterizations of the distribution of prime numbers, given with the hope of helping a better knowledge of the set of prime numbers. The importance of the remainder function in the computational definitions of arithmetic functions leads to reflections on the importance of fundamental operations - addition and multiplication - of natural numbers and the importance of inverse functions - subtraction and division. In turn, these operations can be seen as functions of two variables on the set of natural numbers. From here, readers are invited to reflect on the problem of the origin of natural numbers, the origin based on revelation or the origin provided by set theory, although this may also be a revelation.
Sedimentologic and Petrographic Study of Outcrops of Ajali Sandstone in Okigwe, Uturu and Isiukwuato, Anambra Basin Southeastern Nigeria
Authors: N. D. Enyioko , S. O. Onyekuru , D. O Ikoro , T. L. Ogbonna
Published: May 2022

The Ajali Formation outcrops at Okigwe, Ihube, Onyekaba mine, Uturu and Isiukwuato in the Anambra Basin southeastern Nigeria were evaluated for an integrated field, sedimentologic and petrograpic methods. The study was aimed at presenting a better understanding of the depositional processes and provenance. Five lithofacies were altogether described namely: planar Cross bedded sandstone facies A, Massive sandstone facies B, Ferruginized sandstone facies C, herringbone cross bedded sandstone facies D, and Bioturbated sandstone facies E. The facies were deposited in a fluvially influenced shallow marine environment. The overall grain size interpretation shows that sediments from the study area are fine to coarse grained with values ranging from 0.2 to 2.0Φ, poorly sorted to very well sorted with range value of 0.28 to 1.2Φ, nearly symmetrical to strongly fine skewed with values of -0.04 to 0.59Φ and platykurtic to very leptokurtic with values of 0.79 to 2.46Φ. An inspection of the cumulative frequency curves of the studied samples shows that the sediment population is dominated by saltation population. Texturally, the sandstone sediments are sub-mature containing grains that are moderately to poorly sorted and not well rounded. The Mineral Maturity Index of the sandstone in the study area ranges from 24-49 which falls within the mature to super mature class. The high quartz content and insignificant amount of feldspar and rock fragments further support this assertion. The study suggest the sandstones must have been subjected to substantial high degree of reworking that resulted in the removal of the ferromagnesian minerals and feldspar typical of recycled sediments.

The COVID-19 crisis has disrupted all our lives and this period can be very stressful. We have all been forced to remain at home changing our whole lifestyle, which includes missing routine health check-up. Therefore the priority would be to take care of one’s health at any cost. While we safeguard our general health, there is a tendency to neglect some specific areas such as dental health. With most of the dental offices/clinics remaining closed (for normal dental procedures) across the country during this lockdown, it may not be possible to visit the dentist for routine check up or cleaning. Therefore it is extremely important to keep up with dental homecare.

Preservation of natural tooth in dental arch is ultimate objective of dental treatment. After endodontic treatment, tooth becomes brittle and prone to fracture which results in reduction of strength of crown causing fracture of cusp or sometimes weakness of the roots. In order to strengthen crown some anchorage within teeth has to be made and that anchorage and support is gained by rigid structure which is known as post. This article focuses on recent advances in post systems and their application, merits and demerits in endodontics.

A phylogenetic and morphological study of the Tectaria fuscipes group (Tectariaceae), with description of a new species
Authors: Dong Shi-Yong , Li Shu-Hang , Huang Ling , Tan Shi-Shi , Zuo Zheng-Yu
Published: May 2022

The fern species Tectaria fuscipes and morphologically similar species, which are common in tropical and subtropical mainland Asia, constitute a taxonomically confusing group. To better understand species boundaries and relationships within the T. fuscipes group, we conducted phylogenetic analyses of five plastid regions and morphological observations of herbarium specimens and living plants. As a result, we produced a generally well-resolved phylogeny of the T. fuscipes group and related species in Asia. The phylogenetic analyses supported the monophyly of the T. fuscipes group, which includes T. dissecta, T. fuscipes, T. ingens, T. paradoxa, T. setulosa, T. subfuscipes, T. subsageniacea and a new species, but excludes T. kusukusensis. However, T. fuscipes, T. subfuscipes and T. subsageniacea are almost indistinguishable in morphology, which form a complex characterised by the black linear-lanceolate stipe scales. The new species found in southern China and Vietnam is described here as T. fungii. It is similar to the T. fuscipes complex and T. kusukusensis, but differs from the former mainly by its brown-castaneous lanceolate stipe scales and from the latter by having nearly hairless laminae (versus frond axes abaxially bearing copious hairs).

Aster quanzhouensissp. nov. (Asteraceae) from Fujian, eastern China, is described and illustrated. It grows on rocks in the riparian zone. Morphological, cytological and molecular investigations of A. quanzhouensis were carried out. The morphological data and phylogenetic analysis based on combined ITS, ETS and trnL-F dataset suggest that A. quanzhouensis is a separate species closely related to A. tonglingensis. The new species differs from the latter by the shorter stem length, leaf morphology, colour of phyllaries, number of ray florets, and achene shape. The cytological observation shows that the new species is diploid with a karyotype of 2n = 18.
Do economic inequalities impact demographic dividend: Evidence from India
Authors: Narayana Muttur R.
Published: May 2022

The paper offers a new explanation and prediction of empirical relationship between income and consumption inequalities and demographic dividend. The framework for the analysis is a modified National Transfer Accounts (NTA)-based modelling of the first demographic dividend with inequality-adjusted or inequality-discounted economic support ratio (ESR). The model is tested for India by calculating the inequality-adjusted demographic dividend (or the growth rate of ESR) for the period 2005-2050. The results show that income inequality is not higher than consumption one for all ages and these age-specific economic inequalities have remarkable effects on (i) lowering the observed age-specific distribution of labour income for select ages and consumption for all ages and (ii) reducing the size and duration of demographic dividend due to lower growth rate of ESR. In addition, income inequality effects are found to be stronger than consumption inequality effects in terms of reducing the size of demographic dividend. These results imply that (a) growth effects of the first demographic dividend are upward-biased if unadjusted for the economic inequalities; (b) attainment of goals and targets of the reduction in inequalities under UN-SDGs 2030 by redistributive economic policies are contributory to the maximization of economic growth through the first demographic dividend; and (c) economic inequalities do impact the size and duration of demographic dividend. Subject to the availability of data, the modified approach to the first demographic dividend calculation in this paper is of relevance for comparative studies between India and other countries to draw lessons from mutual experiences and to establish the generality of results.

Background/Aims: L-carnitine is potentially beneficial in patients with hepatic encephalopathy (HE). We aimed to evaluate the impact of L-carnitine on the quality of life and liver function in patients with liver cirrhosis and covert HE.Methods: We conducted an investigator-initiated, prospective, multi-center, double- blind, randomized phase III trial in patients with covert HE. A total of 150 patients were randomized 1:1 to L-carnitine (2 g/day) or placebo for 24 weeks. Changes in quality of life and liver function were assessed at 6 months. The model for end-stage liver disease (MELD), the 36-Item Short Form Survey (SF-36), the psychometric hepatic encephalopathy score (PHES), and the Stroop Test were evaluated in all patients.Results: The total SF-36 score significantly improved in the L-carnitine group after 24 weeks (difference: median, 2; interquartile range, 0 to 11; p < 0.001); however, these values were comparable between the two groups. Furthermore, there was a significant ordinal improvement in PHES scores among patients with minimal HE who were in the L-carnitine group (p = 0.007). Changes in the total carnitine level also positively correlated with improvements in the Stroop test in the L-carnitine group (color test, r = 0.3; word test, r = 0.4; inhibition test, r = 0.5; inhibition/switching test, r = 0.3; all p < 0.05). Nevertheless, the MELD scores at week 24 did not differ between the groups.Conclusions: Twenty-four weeks of L-carnitine supplementation was safe but ineffective in improving quality of life and liver function.

The lipid, protein, chitin, and mineral composition of black soldier fly larvae and adults reared on spent brewer’s grain and Gainesville diet were determined via a suite of analytical techniques. The lipid profile of larvae was dominated by triacylglycerol-bound (83.3 wt.%) saturated, unsaturated, and methyl-branched fatty acids. Cyclopropane and oxo fatty acids were identified as minor constituents (up to ~0.7 wt.%). Adults possessed a similar fatty acid profile to larvae, with free fatty acids (54 wt.%) representing the dominant species. Unsaponifiable lipids consisted of trace alcohols and sterols in addition ton- and methyl-branched alkanes (~4.6 wt.%). Larvae and adult protein isolates were dominated by glutelins followed by prolamins, globulins, and albumins. These proteins were bound, and the typical isolate preparation procedure yielded very low recoveries (~1.4-7.7 wt.%). The surface hydrophobicity, oiland water-holding capacity of the protein isolates were determined to highlight the functionality of insect proteins. The information presented herein will serve to further the utilisation of the black soldier fly larvae and adults as food, food ingredients, and feed.
Multimodal correlations-based data clustering
Authors: Chen Jia , Schizas Ioannis D.
Published: May 2022

This work proposes a novel technique for clustering multimodal data according to their information content. Statistical correlations present in data that contain similar information are exploited to perform the clustering task. Specifically, multiset canonical correlation analysis is equipped with norm-one regularization mechanisms to identify clusters within different types of data that share the same information content. A pertinent minimization formulation is put forth, while block coordinate descent is employed to derive a batch clustering algorithm which achieves better clustering performance than existing alternatives. Relying on subgradient descent, an online clustering approach is derived which substantially lowers computational complexity compared to the batch approach, while not compromising significantly the clustering performance. It is established that for an increasing number of data the novel regularized multiset framework is able to correctly cluster the multimodal data entries. Further, it is proved that the online clustering scheme converges with probability one to a stationary point of the ensemble regularized multiset correlations cost having the potential to recover the correct clusters. Extensive numerical tests demonstrate that the novel clustering scheme outperforms existing alternatives, while the online scheme achieves substantial computational savings.
Mathematical modeling and analysis of the effect of the rugose spiraling whitefly on coconut trees
Authors: Govindaraj Suganya , Rathinam Senthamarai
Published: May 2022

Coconut trees are severely affected by the rugose spiraling whitefly (Aleurodicus rugioperculatus Martin), which is an exotic pest. The dynamics of the disease caused by this pest are analyzed using a mathematical model. The equilibrium points are proved to be locally and globally asymptotically stable under some conditions. Our study, with sensitivity analysis, reveals that the contact rate plays a crucial role in the system that has a direct impact on disease spread. Further, with optimal control, we evoke the optimum level of spraying insecticide, which results in better control over disease with minimum cost of spraying. Additionally, an approximate analytical solution has been derived using a homotopy analysis method. The $ \hbar $-curves are provided to validate the region of convergence. The analytical results are compared with the results of numerical simulation and they are found to be in good agreement. Our goal is to keep the spread under control so that yield is unaffected. Controlling the contact rate with control measures can reduce the risk of healthy trees becoming infected and the intensity of infection.
A Stakeholder Analysis of the Artificial Reefs in Edremit Bay, Turkey
Authors: Tunca Sezgin , Lizaso Jose Luis Sanchez , Ünal Vahdet
Published: May 2022

Artificial reefs (ARs) have gained considerable attention in Turkey, due to their positive biological and socioeconomic implications. The most recent and comprehensive AR deployment was completed in Edremit Bay. The authors investigated the stakeholders' perception and satisfaction along with social, economic, and management concerns about the AR deployment for the period October-December 2014. They first defined user and non-user AR stakeholders and their interests in the project. They represented multiple interactions among stakeholders about the AR deployment by focusing on user types, attitudes, or behaviors towards the AR deployment. They queried existing and potential problems about the project and the deployment area to produce consistent management solutions. They suggest that public participation and multiple collaboration would enhance communication and deal among the stakeholders towards finding solutions for the existing problems. Future studies should reveal social, economic, and management aspects of the stakeholders by the medium and long-term monitoring studies.

The value of and guidance provided by mentors on the author's journey from deciding to become a K-12 educator to teaching science methods at the higher education level is examined in this chapter. Additional influences explored are those that come from professional networks. Through scenarios and reflection, lessons learned are considered with recommendations to be considered.
Reflections of an Academic Father
Authors: Stewart Trevor Thomas
Published: May 2022

This chapter discusses the complexity of balancing the professional and personal goals and identities that can often seem incongruent as teacher educators manage the demands of life in the academy. The author explores that complexity by discussing what he learned from reflecting upon his efforts to balance the tension between his professional and personal goals as an academic and as a father. He draws upon dialogical-self theory to discuss ways the facets of one's identity can be brought into dialogue with one another as people respond to the challenges they encounter. The chapter describes the reflective process of engaging in dialogue with philosophical mentors that supported the author's efforts to manage the tensions created by feeling like his senses-of-self as an academic and as a father were at odds. By sharing his struggles and his reflective process for responding to tension, the author aims to help readers find ways to see tension as a mechanism for growth and their own complex identities as sources of insight.

Authors: Nunamaker Ross Glen Chandler , Mosier William Arthur
Published: May 2022

This chapter explores the integration of disciplinary literacy across learning stations in PreK through 3rd Grade classrooms to facilitate culturally and linguistically responsive learning. Through a synthesis of research and the professional experience of the authors, the chapter offers a conceptual framework and pedagogical support for literacy practices that are culturally and linguistically responsive to each child's emerging and developing literacy. Additionally, this chapter describes the components of an interdisciplinary approach to facilitating literacy learning at the prekindergarten through third grade level that ensures a culturally and linguistically responsive curriculum integrating language arts, mathematics, science, and social studies using learning stations. This model supports self-directed learning facilitated by responsive adult-initiated adult-child interaction in a play-based environment for nurturing intrinsic motivation and self-directed learning.
The Intersection of Disciplinary Literacy, Academic Engagement, and Teaching Diverse Students
Authors: Page Larkin
Published: May 2022

The purpose of this study was to investigate the understandings of informational text of new, in-service, alternatively certified seeking educators, as they teach and engage their students. It is significant to grasp what these teachers knew about informational text, specifically the characteristics, structures, purpose, and types, as well as if these teachers were comfortable using informational text as a teaching resource and what reading comprehension strategies were used with informational text in their classrooms. This study offers implications for these teachers, alternative certification program improvement, and the instructors/professors teaching disciplinary literacy in alternative certification programs.

Authors: Vincent Olusegun , Ikpesu Fredrick , Dakare Olamitunji
Published: May 2022

The studies in corporate governance have explained different motives responsible for adoption of corporate governance. This chapter provides answers to why business should be morally responsible and practice CSR. The authors shed light on crucial areas of corporate responsibilities of business and various theoretical justification advanced in previous studies in CSR. They look at the relationship between CSR and corporate governance – their crucial points of divergence and convergence. They also look at ethics and responsibilities for unethical behaviours and ethical theories with their limitations. Finally, they evaluate CSR and ethics from African perspective – how CSR in Africa is framed from by sociocultural influences, like communalism, ethnic-religious beliefs, and charitable tradition (ubuntu philosophy).
