Environmental impact of urbanization on Santa Eulália Small Farm, São Luís-MA, Brazil
Authors: Rufino Marina de Alcântara , Foicinha José Renato Silva , Alcântara Enner Herenio de 
Published: December 2022

The small farm Santa Eulália occupies a privileged area in the landscape composition
of the city of São Luis, being situated in one of the vectors of urban expansion, the edges of
the avenue Euclides Figueiredo, on the northwest of the island of Maranhão, next to the
center. In the decade of 1980, the small farm was inserted in area of permanent environment
protection and in the beginning of the decade of 1990, Santa Eulália received great landscape
alteration for interest in creating the housing development Santa Eulália for an estimated
population of 35 thousand inhabitants. The intervention was made aiming to organize the
growth of the city, however the execution of the work generated a great controversy, as much
political as environmental, but also social, with the argument that the area destined to the
implantation of the housing development would be of permanent preservation and placed on
the side of a garbage deposit that served as a deposit of solid residues for all the cities of the
island. After the deforestation of 107.32 hectares and the implantation of the primary
infrastructure in the place that involved services of embankment, drainage and pavement, the
work was seized by the Brazilian Institute of the Environment and Renewable Natural
Resources (IBAMA), but the main environmental impacts had already occurred or was
occurring. Due to the land filling, embankment, previous cut of palm trees and mangrove,
some foci of erosion with the creation of several gullies had originated and had a consequent
sanding of creeks due to the material carried by the rain, besides that, the exposed soil is poor
and with lateritic concretions . These factors made it difficult to attempt the forest resetting of
the area in study. Therefore, the recovery of all the area becomes necessary in order to leave
it with a profile similar to the original, mainly in the areas considered untouchable for the
Brazilian environmental legislation.
The problematic of sandy lands in Paranavai Municipality -PR
Authors: Stipp Marcelo Eduardo Freres 
Published: December 2022

The sandy lands are a process of scouring with sand forming a sandy area, which corresponds
to a reworking of the sands due its constant mobility, involving the transformation of not
solids deposits is sandy areas. This work tried to establish the characterization of this
phenomenon of scouring with sand in a local level, occurring in arenaceous areas in the
Northeast of the state of Paraná, specifically in the urban site of Paranavaí. It was also made
an evaluation of the environmental degradation as well as different causes for what provoked
these sandy areas. Being an area with a high level of soil decomposition with the highways
routes crossing it, it was necessary, besides bibliographic data that allowed a theoretical basis,
a research applied in order to supply subsides for future planning related to the space
organization. The evolution of the use and soil occupation in this area has been processed
within an urban planning which considered by no account neither soil characteristic, the
vegetation nor the predominant climate in that region. The mechanisms of region atmosphere
circulation were analyzed, the alterations or attributes of the climate as well, aiming to
identify the genesis of the erosion sandy and possible time and space distribution. Initially, the
main characteristics of the region were collected, components e processes working on the land
model. It was observed how it worked and the use and occupation of the soil in past times and
currently. During 2004, using the Environmental Fragility Letter, the areas of erosion were
identified, ravines and strong erosion that compounds the first stages of the focused problem.
The sandy land is a process that involves erosion, transport, e accumulation, meaning most of
times the loosing of Biosphere productivity. For monitoring these risk areas some measuring
canes were made to measure the soil loss, which were used in several spots of erosion in the
urban area in Paranavaí. The measurement happened in every two months for a year in six
different pre-established spots through satellite image that turned it valid in the study field.
All together, the pluviometrical levels were analyzed to be related to the soil losses. It was observed initially that the causes of these facts were reflection of inappropriate handling of
the urban soil, and in second time it was noticed that it had a broaden reach, involving from
ecological unbalance, to politics, social and economical interests. Among them; the
stabilization of this sand scouring some suggestions were made: the plantation of some trees
in specific seasons of the year which hold the best conditions for their developing, for
instance, during the Winter the temperature is lower and the insolation lower as well,
consequently it provokes a higher level of soil humidity.

OBSERVAÇÃO DE AVES E ECOTURISMO EM ITAMARACÁ (PE): INSTRUMENTOS PARA O DESENVOLVIMENTO SUSTENTÁVEL
Authors: Farias Gilmar Beserra de , Castilho Cláudio Jorge Moura de 
Published: December 2022

A observação de aves ou birdwatching é uma atividade ligada à natureza e se resume em colecionar
registros de aves. Os objetivos deste trabalho foram listar a avifauna existente nos vários ambientes
da ilha de Itamaracá (PE), detectando possíveis ameaças à sua sobrevivência, e verificar o nível
de sustentabilidade turística, na probabilidade de implementar a observação de aves como
ecoturismo na perspectiva do desenvolvimento sustentável. Foram registradas 184 espécies,
destacando-se quatro aves ameaçadas de extinção e 22 migratórias marinhas. Os indicadores de
sustentabilidade que apontaram impactos que afetam as atividades turísticas da ilha foram: UCs
não implementadas, uso desordenado das praias e ineficiência quanto ao saneamento básico,
principalmente no que se refere aos resíduos sólidos. Mesmo assim, Itamaracá se destaca como um
potencial lugar para o desenvolvimento da observação de aves, podendo vir a se transformar em
um instrumento de conservação e promoção dos moradores locais.
A NATUREZA NA CIDADE: UMA ABORDAGEM A PARTIR DA PERCEPÇÃO DA POPULAÇÃO ACERCA DO JARDIM BOTÂNICO DE CURITIBA (PR)
Authors: Hassler Márcio Luís 
Published: December 2022

Torna-se cada vez mais difícil, nos dias atuais, dissociar cidade e natureza, pois o processo de
urbanização influencia e é influenciado pelo entorno de sua área de ocupação, constituindo
meios integrados os quais não se deveria aplicar nenhuma desvinculação ao se elaborar estudos
de problemáticas sócio-ambientais urbanos. A partir da preocupação em analisar as relações
estabelecidas entre a sociedade e natureza questiona-se: 'O que é "Natureza"?' Muito
provavelmente surjam, a partir dessa indagação, várias respostas, relacionadas com o objeto de
estudo ou ainda com a problemática de enfoque. Quando da análise para tentar responder a esta
questão tem-se que levar em conta que o sentido de Natureza é extremamente amplo e possui
diversas definições. Com isso surge a problemática em definir a "Natureza" como tal, num momento
em que se fala amplamente em "defender o meio ambiente" das agressões humanas, ou seja, das
agressões da própria sociedade. A abordagem geográfica da concepção de "natureza" na cidade
se coloca como objetivo principal deste trabalho, que se baseou na percepção para realizar suas
verificações. Neste contexto se insere o Jardim Botânico de Curitiba, que se reflete como "Natureza"
na Cidade, vista de diversas formas por um grupo de pessoas de Curitiba.
CONSIDERAÇÕES SOBRE AS ESTRATÉGIAS E AÇÕES DOS PROMOTORES IMOBILIÁRIO NA PRODUÇÃO DO ESPAÇO URBANO
Authors: Mota Adeir Archanjo da , Mendes Cesar Miranda 
Published: December 2022

Este artigo tem por objetivo discutir a produção do espaço urbano a partir das influências dos
principais agentes sociais. As cidades capitalistas têm como característica principal o processo
de apropriação e produção do solo urbano por meio das estratégias e das ações desenvolvidas
pelas diversas forças do capital (fundiário, imobiliário, produtivo e financeiro). Essas forças do
capital inter-relacionam-se, o que dificulta a compreensão das ações e as estratégias dos diferentes
agentes. Porém enfocamos o capital imobiliário, sobretudo, os promotores imobiliários, por ser,
assim como o Estado, um dos agentes significativo na produção do espaço urbano e para a
reprodução social. Ao capital incorporador, interessa acelerar a atividade das transações no
mercado imobiliário com paulatino aumento no preço dos imóveis, o que gera um aumento na
parcela do orçamento destinado à moradia, dificultando o acesso das classes baixas a um dos
bens indispensáveis e a um dos requisitos principais do direito à cidade. Neste, utilizamos como
referencial teórico à categoria de análise Capital Imobiliário.
OS IMPACTOS AMBIENTAIS E O PROCESSO DE GESTÃO INTEGRADA: EXPERIÊNCIAS NA VILA DE ABRAÃO - ILHA GRANDE, ANGRA DOS REIS (RJ)
Authors: Gama Sônia V. G. da , Leal Filha Sueli Maurício , Rocha Ilana Campos 
Published: December 2022

A Ilha Grande localiza-se entre as coordenadas 44°05'- 44°23' W e 23°05'- 23°14' S no município
de Angra dos Reis, litoral sul do estado do Rio de Janeiro. Com aproximadamente 193KmÂ², tem
dois distritos, o de Araçatiba localizado na porção oeste, cuja principal vila de moradores é
Provetá, e Abraão localizado na porção leste que tem como principal povoado a Vila de Abraão.
A Vila de Abraão é considerada a "capital" da Ilha Grande, onde aportam e transitam diariamente,
moradores, visitantes, usuários, gestores públicos, pesquisadores e ambientalistas. O presente
artigo trata os impactos ambientais na Vila de Abraão como vetores na construção do processo de
gestão e planejamento territorial, principalmente após a mudança de função da Ilha - de sede do
Instituto Penal Cândido Mendes (institucional) e de uso voltado para a preservação ambiental,
passa à sede do Centro de Estudos Ambientais e Desenvolvimento Ambiental (UERJ), também
institucional e voltado à preservação ambiental, mas no contexto do advento da intensificação da
atividade turística.

Study of the phase-transition behavior of (AB)3 type star polystyrene-block-poly(n-butylacrylate) copolymers by the combination of rheology and SAXS
Authors: Shi Qingwen , Zou Jiaqi , Pan Chen , Fu Yin , Supty Mahfzun Nahar , Sun Jiuxiao , Yi Chunlong , Hu Jingchuan , Tan Haiying 
Published: December 2022

Abstract
A series of three-armed star polystyrene-block-poly(n-butylacrylate) copolymers (PS-b-PBA)3 were synthesized to study the phase-transition behavior of the copolymers. The order-to-disorder transition temperature has been determined by oscillatory at different temperatures and dynamic temperature sweep at a fixed frequency. Moreover, the micro-phase separation in the block copolymers has been evaluated by time–temperature superposition, while the free volume and the active energy of the copolymers have been calculated. Interestingly, active energy decreased with the increase in the molecular weight of the PBA components. To further determine the order-to-disorder transition temperature precisely, small angle X-ray scattering was performed at different temperatures. These results confirm that the chain mobility of the star-shaped copolymers is strongly dependent on the arm molecular weight of the star polymers, which will be beneficial for the processing and material preparation of the block copolymers.
Evaluation laboratory prenatal screening performance based on biological variation of risk assessment in second trimester in China
Authors: He Falin , Zhong Kun , Yuan Shuai , Du Yuxuan , Wang Wei , Wang Zhiguo 
Published: December 2022

Abstract

Objectives
This study intends to evaluate prenatal screening risk assessment performance based on biological variation to help clinical laboratories realize their own screening performance and set the appropriate performance specifications for prenatal screening risk assessment in China.

Methods
Fifteen samples with detailed clinical information were distributed to participants and the prenatal screening Down syndrome risk assessment of each sample were submitted. Three levels of performance specification (optimum, desirable, minimum) derived from biological variation were used to evaluate laboratory prenatal screening risk assessment performance.

Results
A total of 797 laboratories participated in the survey project. There are 216 laboratories using serological double-marker test and 581 laboratories using serological triple-marker test. For each screening protocol, more than 92.00% laboratories meet minimum performance specifications, more than 84.00% laboratories meet desirable performance specifications, and only about 62.50%laboratories meet optimum performance specifications. The Feltz and Miller test indicated that there were no significant statistical differences in the RCV for double-marker screening in 5 platforms and triple-marker screening in 6 platforms.

Conclusions
The risk assessment of prenatal screening in the second trimester in China can be improved further. It is appropriate to choose desirable performance specifications for external quality assurance organizations to evaluate the risk assessment performance.
Nonprofits as a Resilient Sector: Implications for Public Policy
Authors: Young Dennis R. 
Published: December 2022

Abstract
Lester Salamon first characterized nonprofits in the United States as “the resilient sector” in 2003. He based this characterization on the sector’s growth, its ability to adapt to new economic and political conditions over time and its increasingly adaptive entrepreneurial culture. The view of nonprofits as resilient institutions has been reinforced since by their performance in recent crises including the COVID pandemic beginning in 2020 and the financial crisis of 2008–2009, though not without exception or assurance that nonprofits would necessarily be resilient in future crises. This paper examines some of the strategies nonprofits have employed to navigate recent crises and prepare themselves for less certain futures. It also teases apart the nature of resilience, asking how resilience at the organizational level differs from network level and sector-level resilience. Such differences have important implications for public policy vis-à-vis nonprofits. In particular, policies that would strengthen nonprofits at the organizational level may differ from, even conflict with, those that would strengthen the nonprofit sector as a whole.
Discussion of ceramic bar reinforced TWIP steel composite structure
Authors: Sun Guo-jin , Qi Wang , Miaoyu Hou 
Published: December 2022

Abstract
A ceramic–steel composite structure which consists of Si3N4 ceramic bars and twinning-induced plasticity (TWIP) steel matrix was prepared using lost foam casting method. Microstructural analysis indicated that the ceramic bars and TWIP steel matrix can form favorable and tight interface. A comparison of mechanical properties between the composite structure and TWIP steel matrix was made. Results show that the bending strength increased from 388 to 805 MPa compared with TWIP steel matrix. The influence of annealing heat treatment on the bending strength of this new type of composite structure was also discussed.
Hypophosphatasia as a plausible cause of vitamin B6 associated mouth pain: a case-report
Authors: Andersen Eline Sandvig , Rasmussen Maria , Brasen Claus Lohman 
Published: December 2022

Abstract

Background
Mouth pain has been associated with abnormal vitamin B6 levels. Hypophosphatasia is a rare genetic disease, which causes imbalances between B6 vitamers. We report the case of a patient with hypophosphatasia and burning mouth pain.

Case presentation
A 39-year old Caucasian male with chronic burning mouth pain underwent extensive investigations with no cause of the pain being found. During the course of the investigation, an elevated vitamin B6 (pyridoxal phosphate) level was detected, which led to the diagnosis of hypophosphatasia. We hypothesize that the patient’s mouth pain stems from hypophosphatasia through a B6 dependent mechanism.

Conclusions
Mouth pain may, in some cases, be a symptom of hypophosphatasia and when investigating B6 in relation to mouth pain, attention should be paid to the exact B6 vitamer measured. The case underlines the importance of low alkaline phosphatase results, especially in patients with unexplained pain, as this should prompt suspicion of hypophosphatasia.
Sociolinguistics in an increasingly technologized reality
Authors: Kelly-Holmes Helen 
Published: December 2022

Abstract
Digital media have become a mainstream source of data for sociolinguistics, reflecting the ubiquity of such media and the centrality of their role in people’s everyday speech as well as changed attitudes towards what constitutes a valid object of study in sociolinguistics. As our personal and professional reality becomes more technologized, there is, however, an urgent need to engage with a deeper understanding of the current and evolving digital economy underpinning this reality in order to assess critically the data that we now encounter. Trends such as personalization, securitization, and hierarchization, for example, mean that the sociolinguistic data we encounter are increasingly shaped by users’ digital identities. In the current digital economy, language is a key tool for steering, recording, and tracking these identities, for example, in the form of algorithms; however, the sociolinguistic dimension to these processes has not yet been explored fully. As well as more integrated approaches to studying digital sociolinguistic data, our increasingly technologized reality demands that we build algorithmic reflexivity into our teaching and our research.
Language policy research directions embedded in the sociolinguistic enterprise
Authors: Kristinsson Ari Páll 
Published: December 2022

AbstractWhile language policy and planning studies are a separate research field in sociolinguistics, they must develop in line with empirical and theoretical findings presented in the other branches of sociolinguistics. The distinctiveness of language policy and planning research lies in its interest in language management, while language practices and language attitudes, beliefs, and ideologies are also objects of study in sociolinguistics in general, as well as in other disciplines in the humanities and social sciences. Language policy and planning studies benefit from work carried out in other research traditions, and this relationship can be mutually beneficial if there is mutual will to exchange ideas, models and approaches. The position argued for in the present contribution is that it can be wise for language policy and planning researchers to take Spolsky’s work on language policy still further, particularly his fundamental assumption that language policy has three interrelated yet independent components, namely language practices, language beliefs, and language management. In doing so, language policy and planning studies can be sure to be at once firmly rooted in a wider research context, while their distinctiveness as a separate sub-field of sociolinguistics is underscored.
Digitale Plattformen als soziale Systeme?Vorarbeiten zu einer allgemeinen Theorie
Authors: Rachlitz Kurt , Waag Philipp , Gehrmann Jan , Grossmann-Hensel Benjamin 
Published: December 2022

ZusammenfassungDie zunehmende Bedeutung digitaler Plattformen für die moderne Gesellschaft wird bisher noch nicht hinreichend von einem übergreifenden Interesse an einer allgemeinen Theorie begleitet. Der Beitrag steuert aus systemtheoretischer Perspektive erste Vorarbeiten zu einem solchen Vorhaben bei. In Abgrenzung zu bestehenden Konzeptualisierungen digitaler Plattformen als Techniken, Märkte, Netzwerke oder Organisationen bestimmt er diese als soziale Systeme sui generis. Insbesondere das Festhalten am Organisationsbegriff eröffnet dabei aussichtsreiche Vergleichspunkte für Funktionsbestimmungen digitaler Plattformen. Anders als Organisationen konstituieren sich diese nicht durch die Konditionierung von Mitgliedschafts-, sondern von Sichtbarkeitserwartungen. Digitale Plattformen leisten analog zu Organisationen eine Maximierung der Generalisierung von Verhaltenserwartungen in allen drei Sinndimensionen zugleich. Anders als Organisationen leisten sie diese Maximierung aber zeitlich über Kognitionen, sachlich über Programme und sozial über materiell-technisierte Spuren.
Organisation und digitale Technologien. Predictive Policing im organisationalen Kontext
Authors: Büchner Stefanie , Dosdall Henrik 
Published: December 2022

ZusammenfassungDie Mehrheit aktueller Studien schätzt das Transformationspotenzial digitaler Technologien für Organisationen hoch ein. In Auseinandersetzung mit dieser Einschätzung entwickelt der Artikel eine konzeptionelle organisationssoziologische Perspektive auf das Verhältnis von Organisation und digitalen Technologien. Wir nutzen diese Perspektive, um den Fall des Predictive Policing in Deutschland zu betrachten und die Entscheidung zur Adaption der Technologie, ihre organisationale Situierung sowie die Rolle des Organisationstyps zu diskutieren. Unsere Perspektive führt zu einem zurückhaltenden Urteil über das Transformationspotenzial dieser digitalen Technologie, die wir daher als Reform unter anderen Reformen begreifen. Insgesamt argumentieren wir dafür, Digitalisierung stärker als bisher als heterogenen Prozess zu verstehen.
A geometric flow on null hypersurfaces of Lorentzian manifolds
Authors: Massamba Fortuné , Ssekajja Samuel 
Published: December 2022

Abstract
We introduce a geometric flow on a screen integrable null hypersurface in terms of its local second fundamental form. We use it to give an alternative proof to the vorticity free Raychaudhuri’s equation for null hypersurface, as well as establishing conditions for the existence of constant mean curvature (CMC) null hypersurfaces, and leaves of constant scalar curvatures.
