Published: October 2020

[The waterways Rivers, especially in lowland areas, often result the elements of highest naturalistic value and play an important role as ecological corridors. Rivers are characterized by high dynamism and biological complexity, and the distribution of several bird species often depends on their physical characteristics and water velocity. During spring 2018, we studied the bird community dwelling in the Arcola Reserve, managed by Lipu, in province of La Spezia (NW Italy), included within the Montemarcello Magra Regional Natural Park (SCZ IT1343502). This site presents a portion of plain woodland with presence of arboreal substrate dominated by Alnus glutinosa, Populus nigra, Populus alba, Salix alba, and a portion consisting of scattered trees, xeric meadows with shrubby formations comprising Rosa canina, Rubus sp., Spartium junceum, Prunus spinosa. Besides, rare reed formations are present. In the 20 hectares of the study area, we carried out field samplings through 8 monitoring sessions since April 23th until June 26th 2018. Overall, we found 62 species of which only 32 were (potentially, probably or certainly) nesting inside the reserve (22 belonging to Passerines and 10 to the non-Passerines species). Nightingale Luscinia megarhynchos (16.87 ± 4.37 individuals), Blackcap Sylvia atricapilla (16 ± 1.41 individuals), Cetti’s Warbler Cettia cetti (13 ± 2.06 individuals), Melodious Warbler (11.88 ± 6.88 individuals), Blackbird Turdus merula (10.75 ± 1.30 individuals) and Great Tit Parus major (9.88 ± 4.04 individuals) were the most abundant species. The density was 62.97 pairs/10 ha, whereas diversity resulted 2.47, this evidencing a considerable degree of complexity, while the evenness value suggests a certain degree of homogeneity in the abundance of the surveyed species. Five dominant species were present. Although the Passerines resulted the most important order in the community, also the non-Passerines showed a value higher than the one reported by other authors, although in less heterogeneous environments. Less than one third of the breeding species resulted to be long migrant species. Results of the present study represent a first step towards the increased knowledge about the avian community of the Arcola Reserve, especially addressed to its administrators as to highlight the need of preserving natural habitats and associated animal and plant species].   [Article in Italian]
A fine-grained bird Atlas as tool for spatial monitoring: a case study from a remnant wetland during the breeding period (Torre Flavia, central Italy)
Authors: Battisti Corrado , Dodaro Giuseppe , Vannuccini Mario
Published: October 2020

During the 2019 breeding period we carried out a bird atlas for a small coastal natural reserve (Torre Flavia wetland, Special Protection Area IT6030020, central Italy), comparing quantitative data of spatial occurrences with records from an analogous study carried out in 2005. From 2005 to 2019 some water-related species increased their frequency of occurrence (Fulica atra, significantly). Among the reed and rush-bed species, Acrocephalus scirpaceus spatially increased and Cisticola juncidis decreased significantly. Among ecotonal, synanthropic and open habitat species, we registered a significant increase of Chloris chloris. A decreasing trend of Passer italiae, Saxicola torquatus, Emberiza calandra, although not significant, may be probably linked to regional or continental factors. Both causes at local (reedbed expansion, rushbed reduction, water-level management) and at larger scale (decline in their continental range) can explain the observed changes in spatial occurrences during this medium-long temporal range. Local atlases can be quick tools useful to drive management strategies in remnant wetlands.

INTRODUCTION: Global education has seen a paradigm shift in the recent years; especially in life sciences, specializations have started sharing common space in applied research and development. Extending the transdisciplinary approach to undergraduate programs, a case study on the introductory course of Biological Engineering program at University of the Republic (Universidad de la República) Uruguay is presented.OBJECTIVES: The COVID-19 pandemic has led to shifting the biological engineering course to virtual modality, changing the pedagogical dynamics. This study aims at analyzing the adaptation to the new model of virtual learning.METHODS: Different course metrics over time has been analyzed along with surveys on students and professors of the course.RESULTS: Despite several new challenges posed by the virtual modality, the overall student-performance didn't decline.CONCLUSION: The biological engineering course presents interesting contents especially in its course design and student engagements, remodeled especially during its virtual mode.
Length spectra of flat metrics coming from $q$-differentials
Authors: Loving Marissa
Published: October 2020

When geometric structures on surfaces are determined by the lengths of curves, it is natural to ask:
which
curves’ lengths do we really need to know? It is a result of Duchin, Leininger, and Rafi that any flat metric induced by a unit-norm quadratic differential is determined by its marked simple length spectrum. We generalize the notion of simple curves to that of

q

-
simple curves
, for any positive integer

q

, and show that the lengths of

q

-simple curves suffice to determine a non-positively curved Euclidean cone metric induced by a

q

-differential.
Lamplighters admit weakly aperiodic SFTs
Authors: Cohen David Bruce
Published: October 2020

Let

A

be a finite set and

G

a group. A closed subset

X

of

A^G

is called a subshift if the action of

G

on

A^G

preserves

X

. If

K

is a closed subset of

A^G

such that membership in

K

is determined by looking at a fixed finite set of coordinates, and

X

is the intersection of all translates of

K

under the action of

G

, then

X

is called a subshift of finite type (SFT). If an SFT is nonempty and contains no finite

G

-orbits, it is said to be weakly aperiodic. A virtually cyclic group has no weakly aperiodic SFT, and Carroll and Penland have conjectured that a group with no weakly aperiodic SFT must be virtually cyclic. Answering a question of Jeandel, we show that lamplighters always admit weakly aperiodic SFTs.

In this paper, we show that if

R

is a compact Riemann surface and

M=R\setminus\bigcup_i D_i

is a domain in

R

whose complement is a union of countably many pairwise disjoint smoothly bounded closed discs,

D_i

, then there is a complete conformal minimal immersion

X\colon M\to\mathbb{R}^3

, extending to a continuous map

X\colon \overline M\to\mathbb{R}^3

, such that

X(bM)=\bigcup_i X(bD_i)

is a union of pairwise disjoint Jordan curves. In particular,

M

is the complex structure of a complete bounded minimal surface in

\mathbb{R}^3

. This extends a recent result for finite bordered Riemann surfaces.

\qquad \tau(y) =\sum_{k,s=0}^m(\tau_{k,s}(x)y^{(m-k)}(x))^{(m-s)},
$$
на конечном интервале $x\in[0,1]$. Здесь функции $\tau_{0,0}$ и $\varrho$
абсолютно непрерывны и положительны, а коэффициенты дифференциального выражения $\tau(y)$ подчинены условиям
$$

где $f^{(-k)}$ обозначает $k$-ю первообразную функции $f$ в смысле теории распределений. Наша цель - получить в этом случае аналоги классических асимптотических представлений типа Биркгофа для фундаментальной системы решений указанного уравнения по спектральному параметру при $\lambda \to \infty$ в некоторых секторах комплексной плоскости $\mathbb C$.
Мы сводим это уравнение к системе уравнений первого порядка вида
$$

где $\rho$ - положительная функция, $\mathrm B$ - матрица с постоянными элементами, элементы матриц $\mathrm A(x)$ и $\mathrm C(x,\lambda)$ - суммируемые функции и выполнено условие $\|\mathrm C(x,\lambda)\|_{L_1}=o(1)$ при $\lambda \to \infty$.
Для таких систем мы получаем новые результаты об асимптотическом представлении фундаментальной матрицы решений, которые используем для асимптотического анализа указанных выше скалярных уравнений высокого порядка.

Integration as a Multi-way Process
Authors: Samaluk Barbara
Published: October 2020

This article explores innovative EU-funded migrant integration projects which emerged in Slovenia after the 2008 global economic crisis. It stems from sociological literature that conceptualises integration as a general societal phenomenon that shields against precarity. By conducting qualitative interviews with those running the studied projects and other stakeholders, this article explores the projects’ drivers, tactics, and their impact on established institutions. The findings show that the projects were established by proactive activists who utilised EU funds to professionalise their activities and engage in partnerships to develop needs-based, cross-sectional and networked provision that empowers migrants and benchmarks professional norms and standards for migrant integration. Its specific contribution lies in uncovering a multi-way integration process that moves away from mainstream approaches to integration, which segregate and demand change only from migrants, and also includes public institutions and servants, professionals and host societies as a whole.
Organisational Climate and the Work-related Learning of Employees
Authors: Ovesni Kristinka
Published: October 2020

The aim of this mixed methods research was to distinguish and to examine models of organisational climate regarding the work-related learning of employees. The theoretical rationale is found in the reflections of the learning supportive organisational climate as the main prerequisite of the process of participatory planning in adult education and learning, and as one of the core pillars in the process of building a learning organisation. For the purposes of triangulation and of complementarity, we adopted quantitative and qualitative methodology. The research was performed online from May to December 2018 and included employees from different companies in the Republic of Serbia. By using an explanatory sequential mixed methods research design with nested samples for the quantitative (Nqn=687) and the qualitative components (Nql=85), three models of organisational climate regarding the work-related learning of employees have been distinguished: the organisational climate of the fear of repression, the service-oriented organisational climate, and the learning supportive organisational climate.
Women and leadership in modern African literature: A focus on Chinua Achebe’s Anthills of Savannah
Authors: Ezenwa-Ohaeto Ngozi , Asuzu Ifeyinwa Success
Published: October 2020

The discourse on women is one which cannot be over- emphasized. The United Nations in its Declaration on the Elimination of Discrimination Against Women in 1980, made expansion of opportunities for women as a key demand. The declaration contends among others, greater the participation of women in decision making. Hence, the present study examines women and leadership in modern African literature to account for their (women) involvement and the impact of their participation cum non participation, focusing on Chinua Achebe’s Anthills of Savannah. The aim is to ascertain women leadership and its impact in the wider society, with reference to Chinua Achebe’s Anthills of Savannah. The study adopts Feminism (Post structural perspective) as its theoretical consideration. Finding from the study shows that women are not adequately represented in leadership positions. However, in cases where they lead, they functioned optimally for the betterment of their society. Beatrice, for instance, a Senior Assistant Secretary in the Ministry of Finance, is a noble female leader who by her role and conduct stood out. She affected those around her positively and was a source of inspiration to Ikem, a male character, in the novel.

Authors: Nanchen Giliane , Schutzbach Kevin , Rotman Samuel , Winzeler Rebecca , Ambühl Patrice , Halfon Matthieu , Pruijm Menno
Published: October 2020

BACKGROUND
Glomerulonephritis is a rare yet serious group of diseases with a high risk of progression to end-stage renal disease. For optimal healthcare planning, detailed epidemiological and demographic data are essential. Despite their clinical relevance, these data are largely lacking in Switzerland.

OBJECTIVE
The objective of this study was to assess the incidence of the different forms of glomerulonephritis in the western part of Switzerland and its changes over the last 10 years, compared with international data.

METHODS
We listed all renal biopsy reports analysed between 2007 and 2016 at the University hospital of Lausanne, the renal pathology reference centre of all hospitals in the cantons of Vaud, Fribourg, Valais and Neuchâtel. Biopsies with a first diagnosis of primary glomerulonephritis were included in the analysis. The incidence was calculated as the number of patients newly diagnosed with glomerulonephritis divided by the number of inhabitants of all the above-mentioned cantons during the year under review, as retrieved from the federal statistical office of Switzerland.

RESULTS
We collected biopsy reports from 864 patients between 2007 and 2016; 168 biopsies met the inclusion criteria. The most common primary glomerulonephritis was IgA nephropathy at 32.7% of cases, followed by lupus nephritis (29.8%) and pauci-immune glomerulonephritis (11.9%). Overall, the mean incidence of glomerulonephritis was 1.3/100,000/year. Between 2007 and 2016, the incidence of all glomerulonephritis taken together remained stable. The same was true for the incidence of IgA nephropathy, lupus nephritis and pauci-immune glomerulonephritis. In contrast, we observed a trend towards higher creatinine levels, proteinuria and degree of interstitial fibrosis at diagnosis.

CONCLUSION
The incidence of glomerulonephritis in the western part of Switzerland was low and remained stable over time, in line with European data.

Nutrition is one of the major component of sustainable energy, optimal body composition, improving physical fitness and maintaining good health status in athletes. The aim of the study is to investigate the effect of nutritional habits on physical fitness parameters of athletes playing in university teams in different sports branches. Height, body weight of the athletes were measured and body mass index (BMI) was calculated. 12 minute run test, 20 meter sprint test, slalom test, sit ups test, push up test, closed kinetic chain upper extremity stability test (CKCUET test), vertical jump test and hand grip strength test (right-left) were applied to the athletes. 72 athletes who participated in the study, 41.7% were female and 58.3% were male. It was found that the majority of athletes (60.0% for women; 66.7% for men) consumed 3-4 meals a day. While the majority of the athletes reported that they skipped meals, the most skipped meal was breakfast (p=0.05). It was observed that the group consuming 5 or more meals covered more distance in standing long jump and vertical jump tests. When the right and left hand grip strength examined, it was shown that the group who consumed 5 or more meals had better performance, but there was no statistically significant difference (p>0.05). As a result, athletes need different nutritional programs depending on factors such as gender, age, sport, training/competition time. A well nourished athlete will have higher physical fitness and concentration ability and maximum efficiency of the training.

Authors: DERECELİ Çağatay
Published: October 2020

Bu çalışmanın amacı Aydın Adnan Menderes Üniversitesi Spor Bilimleri Fakültesi’nde eğitim gören öğrencilerin bazı değişkenlere bağlı olarak mizah tarzları ve alt boyutlarındaki değişimlerin incelenmesidir. Çalışmanın örneklemini Aydın Adnan Menderes Üniversitesi Spor Bilimleri Fakültesi’nde 2020-2021 öğretim yılında öğrenim gören 62’si kadın, 87’si erkek olmak üzere toplam 149 katılımcı oluşturmuştur. Araştırmaya katılan öğrencilerin mizah tarzlarının belirlenmesinde Martin ve ark. (2003) tarafından geliştirilen Mizah Tarzları Ölçeği kullanılmıştır. Ölçek Yerlikaya (2003) tarafından Türkçeye uyarlanmıştır. Katılımcılara, demografik bilgiler ve mizah tarzları ölçeği yüz yüze görüşme tekniği ile uygulatılmıştır. Verilerinin normal dağılım gösterip göstermediği Kolmogorov Smirnov Testi ile sınanmıştır. Verilerin normal dağılım göstermediği anlaşıldığın nonparametrik testler uygulanmıştır. Elde edilen bulgulardan cinsiyet değişkenine göre kendini geliştirici mizah, saldırgan mizah, kendini yıkıcı mizah alt boyutları ve mizah tarzları ölçeği puanı açısından kadın ve erkek öğrenciler arasında istatistiksel olarak anlamlı bir farklılık görülmediği anlaşılmaktadır (p>0.05). Yaş grubu değişkenine göre kendini geliştirici mizah, saldırgan mizah ve kendini yıkıcı mizah alt boyutları açısından öğrenciler arasında istatistiksel olarak anlamlı bir farklılaşmanın olmadığı anlaşılmaktadır (p>0.05). Ancak katılımcı mizah alt boyutu ve mizah tarzları ölçeği toplam puanı açısından öğrenciler arasında istatistiksel olarak anlamlı bir farklılaşmanın olduğu görülmektedir (p<0.05). Çalışmaya katılan öğrencilerin okudukları bölüm değişkenine göre katılımcı mizah, kendini geliştirici mizah, saldırgan mizah, kendini yıkıcı mizah alt boyutları ve mizah tarzları ölçeği puanı açısından öğrenciler arasında istatistiksel olarak anlamlı bir farklılık tespit edilmemiştir (p>0.05). Katılımcıların milli sporcu olma durumuna göre katılımcı mizah, kendini geliştirici mizah, saldırgan mizah, kendini yıkıcı mizah alt boyutları ve mizah tarzları ölçeği puanı açısından öğrenciler arasında istatistiksel olarak anlamlı bir farklılaşmanın olmadığı görülmektedir (p>0.05). Sonuç olarak, yaş ve cinsiyet değişkenleri açısından mizah tarzları ve alt boyutları açısından öğrenciler arasında farklılık saptanmıştır. Bu farklılığın sebebinin kalıtımsal, çevresel faktörlerden kaynaklanabileceği öngörülmektedir.

Akım modlu devrelerin CMOS gerçeklemelerinde, transistörlerin istenmeyen parazitik etkilerinden dolayı devrelerde istenmeyen parazitik empedanslar oluşabilmektedir. Oluşan parazitik empedanslar, sistemin çalışma karakteristiğini değişmesine ve/veya etkilenmesine neden olmaktadır. Parazitik empedansların etkisini azaltabilmek ve sistemi ideal çalışma karakteristiğine yaklaştırabilmek için, devrelerde kullanılan transistörlerin kanal genişlikleri ve kutuplama akımları değiştirilebilir.

Yapılan bu çalışmada, ikinci kuşak akım taşıyıcı devresi üzerindeki parazitik dirençlerin etkilerini azaltabilmek ve terminallere ait bant genişliğini arttırmak için, uygun tasarım parametrelerini tahmin eden bir yapay sinir ağı oluşturulmuştur. Oluşturulan yapay sinir ağı, Elman ağ yapısına sahiptir ve 30 nörona sahip tek gizli katman içermektedir. Yapay sinir ağı eğitilirken 12 farklı eğitim fonksiyonu kullanılmıştır. Eğitimlerde kullanılan veri seti, LTSPICE programı kullanılarak oluşturulmuştur. Veri setinde 9 adet özniteliğe sahip 60 bin veri bulunmaktadır. Verilerin 54 bini eğitimde kullanılırken 6 bin veri test için ayrılmıştır. Yapılan testlerde en ideal sonucu Scaled Conjugate Gradient eğitim algoritması vermiştir. Eğitilen yapay sinir ağının hata oranı, ortalama %4,59 olarak bulunmuştur.

Bu çalışmada vortex yöntemi ile AZ91 magnezyum alaşımı içerisine % 3, % 6, % 9 ve % 12 oranında zirkonya (ZrO2) katkılanarak bir tür kompozit malzeme üretilmiştir. İlk olarak üretilen kompozit malzemelerin mikroyapıları incelenmiştir. İkinci aşamada Brinell yöntemiyle sertlik ölçümleri yapılmıştır. Daha sonra üç nokta eğme prensibine göre çapraz kırılma deneyleri gerçekleştirilmiştir. Son olarak kompozit malzemelerin abrasif aşınma davranışlarını belirlemek üzere pin-on disk yöntemine göre aşınma deneyleri yapılmıştır. Abrasif aşınma deneylerinde; 10, 30, 50 N olmak üzere üç farklı deney yükü ve 12, 20, 50 m olmak üzere üç farklı aşındırıcı boyutunda zımpara kullanılmıştır. Deney ve incelemeler sonucunda, kısmen homojen bir mikroyapı elde edildiği görülmüştür. AZ91 alaşımı ile katkı elemanı zirkonya parçacıkları arasındaki ıslatmanın iyi olduğu ve güçlü arayüzey bağı meydana geldiği anlaşılmıştır. Zirkonya katkısı ile kompozit yapının sertliğinin ve aşınma direncinin arttığı tespit edilmiştir. AZ91 magnezyum alaşımı içerisine katkılanan zirkonya ile AZ91 kompozit malzemenin mekanik özellikleri yükselmiştir.

Görüntü işlemede en temel konulardan biri eşikleme yöntemidir. Bu yöntem, yaygın olarak gri tonlamalı görüntülerdeki farklı homojenliğe sahip bölgelerin bölütlenmesinde kullanılmakla birlikte renkli görüntülerin bölütlenmesi için de tercih edilir. Bu çalışmada, gri ölçekli görüntüler üzerinde global eşikleme yapabilen 14 farklı algoritma; kümeleme tabanlı, entropi tabanlı, şekil tabanlı ve öznitelik benzerliğine dayalı olmak üzere kategorize edilmiş ve detaylı olarak incelenmiştir. Algoritmaların performansını test etmek için 15 farklı görüntüden oluşan bir veri seti hazırlanmıştır. Bu görüntüler için dört uzman tarafından el yordamıyla eşik değeri belirlenmiş ve ortalama değeri alınarak referans ikili görüntüler elde edilmiştir. Buna göre her bir algoritmanın ürettiği ikili görüntüler, Jaccard Index yöntemiyle referans görüntülere olan benzerlik oranları incelenmiştir. Deneysel çalışmalarda, elde edilen benzerlik oranı ortalamasına göre en yüksek skor yaklaşık %95 ile IsoData ve Otsu algoritmalarına ait olduğu görülmüştür.

Published: October 2020

Current practices in scientific publishing are unsuitable for rapidly changing fields and for presenting updatable data sets and software tools. In this regard, and as part of our continuing pursuit of pushing scientific publishing to match the needs of modern research, we are delighted to announce the launch of GigaByte, an online open-access, open data journal that aims to be a new way to publish research following the software paradigm: CODE, RELEASE, FORK, UPDATE and REPEAT. Following on the success of GigaScience in promoting data sharing and reproducibility of research, its new sister, GigaByte, aims to take this even further. With a focus on short articles, using a questionnaire-style review process, and combining that with the custom built publishing infrastructure from River Valley Technologies, we now have a cutting edge, XML-first publishing platform designed specifically to make the entire publication process easier, quicker, more interactive, and better suited to the speed needed to communicate modern research.
AULAS DE ARTES EM TEMPOS DE PANDEMIA E ATIVIDADES REMOTAS: COMO MANTER O VÍNCULO DO PROFESSOR COM OS ALUNOS, E DOS ALUNOS COM A DISCIPLINA?
Authors: Fachel de Medeiros Rosana
Published: October 2020

Resumo

Com a pandemia de Coronavírus escolas do mundo inteiro foram fechadas impossibilitando as aulas presenciais. Nessa nova perspectiva, o contato dos professores com os alunos passou a ser realizado virtualmente, principalmente a partir de atividades que começaram a ser disponibilizadas online. Nesse texto, apresento uma experiência com a disciplina de artes a partir de atividades remotas para alunos dos Anos Finais do Ensino Fundamental. Na realidade da escola onde trabalho não conseguimos que todos os alunos tivessem acesso aos materiais propostos, em contrapartida, ficou evidente a dedicação e a qualidade dos trabalhos dos alunos que receberam e realizaram as atividades. Também foram positivas as trocas de experiências com os colegas professores. Nesse período de quarentena, ficou evidente a potencialidade de uma educação híbrida (MORAN, 2017) na qual o ensino online, combinado ao presencial poderão oportunizar a personalização da aprendizagem e o protagonismo do estudante (BACICH; TANZIN NETO e TREVISANI, 2015).

La misma se desarrolló durante el primer cuatrimestre del año 2020, como alternativa pedagógica ante la emergencia sanitaria por COVID 19 y el aislamiento social preventivo y obligatorio determinado para todo el territorio argentino. Desde una perspectiva sociocrítica, se reflexiona sobre las prácticas de educación a distancia implementadas en este contexto. Para para sostener la esencia del compromiso social universitario y de la educación crítica, dialógica, emancipadora y transformadora se diseñó una planificación educativa que permitió sostener la calidad educativa, los aprendizajes y la inclusión de los estudiantes en la virtualidad. Se analiza el formato de clases para que sean problematizadoras y habiliten la construcción de aprendizajes significativos; los modos para sostener el acompañamiento, la inclusión y los vínculos pedagógicos; la identificación de estudiantes con contextos disímiles; y la modalidad de evaluación de los aprendizajes desde una perspectiva crítica. Finalmente, se reflexiona acerca de la necesidad de problematizar el presente y el futuro de la educación, en tiempos de pandemia y pospandemia, para profundizar las democracias, la participación ciudadana,  la justicia social y la solidaridad.

Published: October 2020

A afetividade está presente nos diversos grupos de relações humanas e inclusive na área escolar. No contexto educacional, pode ajudar ou prejudicar os resultados esperados dependendo dos vínculos estabelecidos. No caso da relação professor/aluno as relações afetivas podem influenciar no processo de aprendizagem e na preferência dos alunos por alguma área do conhecimento. Assim o presente trabalho tem por objetivo fazer reflexões

sobre a importância das relações afetivas no contexto ensino-aprendizagem. Para tanto, considerou-se também o papel do professor como um dos principais pontos. Foi possível perceber durante a pesquisa bibliográfica feita que os teóricos apontam a real necessidade das relações afetivas no ambiente escolar. São essas relações as quais podem determinar o sucesso do educando na escola e, principalmente, em sua vida futura como cidadão que agirá na sociedade para transformá-la. Nesse contexto, é preciso, pois, observar as contribuições para o desenvolvimento intelectual e emocional, e a compreensão dos educadores de que os alunos necessitam de um ambiente acolhedor e humanizado.

The article examines certain legal and organizational problems in the field of the execution of sentences and other measures of a criminal-legal without isolation of a convict from society, presents the results of a survey of employees of penal inspectorates of territorial bodies of the Federal Penal Service and outlines ways to solve existing problems. The study showed that the formation of a system for the execution of sentences without the isolation of a convicted person from society has not yet been completed. Improvement of criminal and penal legislation is required, a clearer legal regulation of the legal responsibility of convicts, further expansion of the range of powers and functions of penal inspectorates, overcoming difficulties in the organizational, personnel, financial and information support of their activities. The article points to the execution of a number of functions unusual for them by the penal inspectorates, the lack of legal regulation of the execution of certain preventive measures and measures of a criminal-legal nature, the procedure for determining the list of objects for convicts to serve sentences in the form of correctional labor and compulsory labor as well as the procedure ensuring the attendance of convicts at the hearing. The legislation does not provide for the initial measures to establish the whereabouts of convicts to punishment in the form of deprivation of the right to occupy certain positions or engage in certain activities, the issue of appealing directly by employees of penal inspectorates of court decisions on representations against convicts is not regulated.

The concepts "morphotype of residential development" and "second home" are defined. Morphotypes of residential development are distinguished by three characteristics: social order, residential unit’s living space per family member, and weighted average time spent on travelling from place of residence to socially most significant areas of the city. Overall, 17 housing morphotypes have been identified, including five types of second housing. The percentage of each type of housing in the total number of residential units in the city is determined. A graph showing growth in the number of garden houses in Penza since the second half of the twentieth century is presented. A diagram of increase in the weighted average number of storeys in residential buildings is provided for some Russian cities. Urban development trends and dependencies in the evolution of the morphological types of urban residential development are revealed, including: permanent growth in living space per family member, globalization and loss of national identity of residential development morphotypes in the late twentieth century, continuing growth in the number of second homes, etc.

Authors: Magos Kostas , Kalopita Konstantina
Published: October 2020

The management of diversity in preschool framework are today one of the main goals of early childhood education. Ιn addition to the school environment, the family also plays a key role in promoting, or not, the acceptance of diversity. The positions and attitudes of parents employed by their children affect, directly or indirectly, the pedagogical practices that teachers usually develop. The purpose of this research was to investigate the perceptions of parents with preschool children about issues of managing diversity in the context of preschool education. Also, this research aimed to determine whether and to what extent the family environment makes efforts to raise young children’s awareness across cultural diversity. The research emerged that about half of the parents, although they initially invoked a neutral attitude towards the cultural diversity encountered in the kindergarten classes, in their deepest views seem to accept the otherness only if it does not make its appearance clearly visible in the classroom.

Abstract

Objectives: To determine the role of heart fatty acid-binding protein in early detection of non-ST-elevation myocardial infarction and its comparison with two other cardiac markers.

Methods: The cross-sectional study was conducted at Abbasi Shaheed Hospital, Karachi, from June 2012 to June 2014, and comprised patients presenting at the emergency department within two hours of chest pain and who were subsequently referred to the cardiology department with a provisional diagnosis of either unstable angina or non-ST-elevation myocardial infarction.  Relevant history was taken on a specific proforma and electrocardiogram as well as routine investigations were done in the emergency department. Blood samples from the subjects were tested for the diagnosis of myocardial infarction through detection of heart fatty acid-binding protein, Troponin-I and Creatine kinase-myocardial band. Sensitivity and specificity of the three markers were calculated keeping coronary angiography as the gold standard. Data was analysed using SPSS 17.

Results: Out of 250 patients, 153(61.2%) were males. The overall mean age was 54.45±13.92 years. Sensitivity and specificity of heart fatty acid-binding protein were 80.6% and 78.5% (p<0.05), for Troponin-I, 37.7% and 75% (p>0.05), and for Creatine Kinase-myocardial band, 29.5% and 67.8% (p>0.05).

Conclusion: Heart fatty acid-binding protein was found to be a good diagnostic tool for the detection of non-ST-elevation myocardial infarction.

Published: October 2020

Bu araştırmanın amacı; sosyal bilgiler öğretim programına yönelik olarak öğretmen adayları tarafından gerçekleştirilen Mobil Artırılmış Gerçeklik (MAG) etkinliklerini değerlendirmek, katılımcılar üzerindeki etkilerini ortaya çıkarmaktır. Araştırmada nitel araştırma yöntemlerinden biri olarak kabul edilen eylem araştırması benimsenmiştir. Araştırmanın çalışma grubunu 2018-2019 akademik yılının bahar döneminde bir devlet üniversitesinin sosyal bilgiler öğretmenliği 2. sınıfında öğrenim gören toplam 46 öğretmen adayı oluşturmuştur. Araştırmada veri toplama aracı olarak Teknoloji Entegrasyonu Öz Yeterlilik Algısı Ölçeği, Anlamsal Farklılıklar Ölçeği ve Kişisel Bilgi Formları kullanılmışken, öğretmen adaylarının hazırlamış olduğu artırılmış gerçeklik uygulamaları, araştırmacı gözlem raporları ve araştırmacı günlüğü de araştırma verisi olarak kullanılmıştır. Veri analizi aşamasında katılımcıların gerçekleştirmiş olduğu çalışmalar dereceli puanlama anahtarları (DPA) ile grup ve toplu olarak değerlendirmiştir. Gözlem raporlarından ve araştırmacı günlüğünden elde edilen veriler DPA’dan ulaşılan sonuçları desteklemek amacıyla kullanılmıştır. Ayrıca, teknoloji entegrasyonu öz yeterlilik algısı ölçeğinden alınan puanların karşılaştırılması için bağımlı gruplar için t-testi, anlamsal farklılıklar ölçeği için de yüzde ve frekans analizi yapılmıştır. Ortaya çıkan bulgulara dayanılarak ulaşılan sonuçlar ise; katılımcıların yapmış oldukları ürünler değerlendirildiğinde nitelikli ürünler ortaya koydukları anlaşılmıştır. Diğer yandan katılımcılara uygulanan t-testi neticesinde anlamlı bir fark ortaya çıkmadığı görülmüştür. Son olarak katılımcıların artırılmış gerçeklik uygulamalarını yenilikçi, kafa karıştırıcı, eğlenceli, zor, sıra dışı, karmaşık ve yorucu olarak değerlendirdikleri görülmüştür.
