Bezpieczeństwo stosowania probiotyków przez ludzi
Authors: Sionek Barbara , Kołożyn-Krajewska Danuta
Published: October 2021

Probiotyki są postrzegane przez konsumentów jako naturalne składniki żywności, których stosowanie przynosi korzyści zdrowotne. Liczne badania przeprowadzone w populacji ludzi zdrowych wskazują na dobrą tolerancję probiotyków. Zdarzenia niepożądane występują rzadko, są najczęściej łagodne i nie wymagają dodatkowych interwencji. W przypadku grup osób o zwiększonym ryzyku działań niepożądanych należy się liczyć z możliwością nawet ciężkich powikłań. W grupie najciężej chorych probiotyki mogą przynieść największe korzyści, jednak decyzja o ich zastosowaniu powinna uwzględniać potencjalne zagrożenia powikłaniami. Mimo przeprowadzenia licznych badań oraz metaanaliz nie udało się niestety określić precyzyjnych wskazań i przeciwwskazań do stosowania probiotyków. Obecnie obowiązujące regulacje i przepisy dotyczące stosowania probiotyków nie są jednolite. W Ameryce Północnej kluczowe znaczenie ma zasada długiego, bezpiecznego dla zdrowia stosowania mikroorganizmu, tzw. status GRAS (ang. Generally Recognized as Safe). W Unii Europejskiej odpowiedzialny za regulacje, ocenę i monitorowanie bezpieczeństwa probiotyków jest Europejski Urząd Bezpieczeństwa Żywności (EFSA). Obowiązuje lista mikroorganizmów, które zostały uznane za bezpieczne i są dopuszczone do stosowania (ang. Qualified Presumption of Safety – QPS). Zarówno w Ameryce Północnej, jak i w Europie przepisy są restrykcyjne, a dopuszczenie mikroorganizmu wymaga przeprowadzenia licznych i drogich badań naukowych. W pracy oceniono bezpieczeństwo stosowania probiotyków w grupie ludzi zdrowych i o podwyższonym ryzyku wystąpienia działań niepożądanych oraz dokonano przeglądu dokumentów regulujących bezpieczne stosowanie mikroorganizmów probiotycznych.

Prognozowanie mikrobiologiczne polega na założeniu powtarzalności odpowiedzi populacji drobnoustrojów na zadane czynniki środowiska produktu żywnościowego. Na podstawie danych empirycznych pochodzących z doświadczeń mikrobiologicznych opracowywane są modele prognostyczne jako programy komputerowe bądź bazy danych dostępne on-line. Celem pracy było utworzenie bazy danych modeli prognostycznych bakterii potencjalnie probiotycznych, saprofitycznych i patogennych w formie użytecznego dla odbiorcy końcowego narzędzia zainstalowanego na serwerze SGGW pod nazwą ProgBaz SGGW. Materiał do badań stanowiły matematyczne modele wzrostu i przeżywalności bakterii saprofitycznych (psychrotrofów, Pseudomonas spp., drożdzy i pleśni) i patogennych: Salmonella spp., Staphylococcus aureus, Listeria monocytogenes (mikroflory niekorzystnej) oraz potencjalnie probiotycznych szczepów z rodzaju Lactobacillus (mikroflory korzystnej). Modele opracowano w Zakładzie Higieny i Zarządzania Jakością Żywności Wydziału Nauk o Żywieniu Człowieka i Konsumpcji SGGW w Warszawie, w latach 1997 - 2008. ProgBaz jest dostępny na stronie głównej SGGW w Warszawie w zakładce Gospodarka oraz na stronie Wydziału Nauk o Żywieniu Człowieka i Konsumpcji SGGW w zakładce Nauka i Usługi. Użytkownik może dokonać oszacowania wzrostu lub przeżywalności drobnoustrojów w czasie pod wpływem czynników środowiskowych (temperatury, poziomu NaCl, poziomu NaNO2, dodatku inuliny) w następujących produktach: modelowym produkcie z mięsa rozdrobnionego, produktach rynkowych mlecznych, mięsnych i warzywnych. Oprócz prognozy wzrostu możliwe jest uzyskanie informacji na temat cech populacji (, , GT, N) oraz w przypadku modelu walidowanego – jakości prognoz. Są to informacje pozwalające oszacować bezpieczeństwo produktu oraz jego termin przydatności do spożycia. ProgBaz może być stosowany do oceny ryzyka mikrobiologicznego żywności, opracowywania planów bezpieczeństwa żywności, ograniczania marnotrawstwa żywności, projektowania nowych produktów oraz stanowić narzędzie edukacyjne i szkoleniowe.
Wpływ wybranych składników żywności na zachowanie żywotności bakterii Lactobacillus spp. w przewodzie pokarmowym – badania in vitro

Published: October 2021

Celem badań była ocena przeżywalności wybranych szczepów bakterii Lactobacillus wyizolowanych z sera oscypkowego i korycińskiego w warunkach in vitro modelu przewodu pokarmowego w zależności od zastosowanych dodatków żywnościowych. Zakres prac obejmował ocenę przeżywalności bakterii po 2 i 5 h inkubacji w modelowym układzie symulującym pasaż żołądkowo-jelitowy w zależności od zastosowanego dodatku ochronnego: mleka UHT (o zawartości tłuszczu 3,2 %), śmietanki (o zawartości tłuszczu 36 %), a także 10-procentowych roztworów inuliny i oligofruktozy. Wykazano, że badane szczepy były oporne na sok żołądkowy o pH = 2,5, natomiast model soku żołądkowego o pH = 2 powodował zmniejszenie żywotności bakterii średnio o ok. 5 rzędów logarytmicznych po 2 h inkubacji. Mleko UHT wykazało nieznaczne działanie ochronne na przeżywalność komórek bakterii, porównywalne do inuliny i oligofruktozy w środowisku obniżonego pH, przy zastosowanej metodzie badawczej. Istotny efekt ochronny na przeżywalność komórek bakterii badanych szczepów stwierdzono natomiast w przypadku zastosowania śmietanki, co najprawdopodobniej ma związek z większą zawartością tłuszczu w porównaniu z jego zawartością w mleku. Badane szczepy, Lb. plantarum (Kor1 oraz Os1) wyizolowane z żywności, charakteryzowały się podobnymi właściwościami jak szczep referencyjny Lb. plantarum 299v, co świadczyć może o potencjalnych właściwościach probiotycznych w tym zakresie. Przeprowadzone badania wskazują na zasadność dalszych badań potwierdzających probiotyczne właściwości i potencjalne zastosowanie jako probiotyków bakterii wyizolowanych z żywności fermentowanej.

Authors: Markowiak-Kopeć Paulina , Śliżewska Katarzyna
Published: October 2021

Celem pracy była ocena przeżywalności probiotycznych szczepów bakterii Lactobacillus spp. i drożdży Saccharomyces cerevisiae podawanych bez dodatku paszy lub z jej udziałem w warunkach modelowych, symulujących wybrane odcinki przewodu pokarmowego drobiu. Mikroorganizmy te wchodzą w skład nowo opracowanych mieszanek probiotycznych (A, B i C). Przeżywalność badanych bakterii i drożdży w symulowanych warunkach wola, żołądka i jelita cienkiego oznaczano metodą hodowlaną. Początkowo średnia liczba bakterii Lactobacillus spp. wynosiła (1,00 ÷ 1,95) × 109 jtk/ml, natomiast drożdży – (1,04 ÷ 3,00) × 107 jtk/ml. W wyniku pasażu próbek bez dodatku paszy liczba bakterii oraz drożdży ulegała obniżeniu w kolejnych odcinkach symulowanego przewodu pokarmowego i w jelicie cienkim była niższa średnio o 2 rzędy wielkości. W obecności paszy natomiast liczba bakterii Lactobacillus spp. w jelicie cienkim była wyższa średnio o 1 rząd wielkości, a drożdży – średnio o 1,5 rzędu wielkości w porównaniu z mieszankami bez dodatku paszy. Dodatek paszy stanowił zatem czynnik ochronny przed niekorzystnymi warunkami środowiska układu pokarmowego w badaniach modelowych. Na podstawie uzyskanych wyników można wskazać na potencjalne zastosowanie mieszanek probiotycznych jako dodatku do pasz dla drobiu.

Published: October 2021

Celem pracy była izolacja i identyfikacja szczepów bakterii kwasu octowego (AAB) w systemie polifazowym oraz wstępne zdefiniowanie in vitro ich potencjalnych właściwości probiotycznych w warunkach laboratoryjnych. Materiał do izolacji bakterii kwasu octowego stanowiły owoce sezonowe pochodzące z lokalnych upraw z województwa mazowieckiego i łódzkiego oraz kultura startowa do produkcji Kombuchy. Identyfikację szczepów przeprowadzono z zastosowaniem systemu polifazowego bazującego na charakterystyce morfologicznej, uzdolnieniach biochemicznych i identyfikacji genetycznej. Na podstawie otrzymanych wyników utworzono kolekcję szczepów AAB bezpiecznych dla zdrowia ludzi, następnie określono antybiotykowrażliwość na 12 wybranych substancji bakteriobójczych i wykonano testy in vitro przeżywalności wyselekcjonowanych szczepów w warunkach modelowego przewodu pokarmowego człowieka. Na podstawie analizy fenotypu i sekwencjonowania genu 16S rRNA spośród 9 izolatów bakterii kwasu octowego do badań wybrano 3 szczepy należące do gatunku Gluconobacter oxydans: H31 wyizolowany z czarnej porzeczki oraz H30 i H32 – z kultury startowej do produkcji herbaty Kombucha. Stwierdzono, że 2 szczepy: G. oxydans H30 wyizolowany z Kombuchy i G. oxydans H31 pochodzący z czarnej porzeczki charakteryzują się dobrą przeżywalnością średnio na poziomie 6 log jtk/ml podczas pasażu przez modelowy układ pokarmowy człowieka i tym samym spełniają jedno z podstawowych kryteriów dla bakterii potencjalnie probiotycznych. Wszystkie badane szczepy wykazywały zbliżoną antybiotykowrażliwość. Przeprowadzona diagnostyka wyselekcjonowanych szczepów bakterii kwasu octowego stanowi podstawę do dalszych badań tych mikroorganizmów w kierunku potwierdzenia pozostałych cech probiotycznych.

Authors: Wirkijowska Anna , Zarzycki Piotr , Noworolnik Kazimierz , Leszczyńska Danuta
Published: October 2021

The objective of the research study was to determine the effect of nitrogen fertilisation level on changes in the technological value of five spring barley cultivars intended for food production. A pot experiment with spring barley was performed in the greenhouse run by the Institute of Soil Science and Plant Cultivation. The barley cultivars studied were compared for the quantity and quality of grain yield including their response to three levels of nitrogen fertilisation (NH4NO3): 1, 2 and 3 g N/pot. The nitrogen fertilisation level proved to have a significant effect on the yield and quality of grains of the barley cultivars examined. With the increase in the nitrogen dose levels to 3 g/pot, a significant increase was reported in the grain yield and number of spikes per pot in all the spring barley cultivars, however there was a decrease in the weight of 1000 kernels. The levels of nitrogen fertilisation and the barley cultivars proved to have a significant impact on the contents of total dietary fibre (TDF) and (1,3)(1,4)-β-D-glucans but no interaction was found between the level of fertilisation and the cultivar. Significantly higher contents of TDF and (1,3)(1,4)-β-D-glucans were reported in the examined spring barley cultivars at a dose of 2 and 3 g N/pot compared to 1 g N/pot. With the increase in the nitrogen dose to 3 g N/pot, a significant increase was reported in the protein content in all the cultivars. Owing to the highest contents of dietary fibre and (1,3)(1,4)-β-D-glucans, and to a high protein content, the ‘Bordo’ and ‘Tocada’ varieties can be recommended as the best varieties to produce food.
The role of eco-innovations in developing sustainable products
Authors: Adamczyk Wacław
Published: October 2021

A characteristic feature that is directly or indirectly related to a quality of sustainable product originating from eco-innovation are the relationships with customers, which consist in meeting their needs and expectancies. However, those customer needs and expectancies are not always consistent with the concept of sustainable development. The customer is a very important link in performing the “customer to customer” quality management process for he is a source of information and a recipient of market offers. However, due to their potential and creativity, designers and constructors are those, who finally play a significant role in developing the quality of sustainable product. The objective of the research study was analysis of the context of sustainable product in the light of the theory of quality management and sustainable development, competitive role of eco-innovations and consumer perception. Based on the reference literature analysis, a thesis has been formulated that the diffusion of eco-innovations is a stimulus to developing a sustainable product. Eco-innovations are perceived by manufacturers as a source of gaining a competitive advantage. On the basis of surveys of the manufacturers of food and electronic equipment, there were established the competitiveness determinants for product eco-innovations. Also, customer surveys were conducted to identify the most common sources of information about eco-innovations. It has been shown that descriptive characteristics of food products and the designation of energy classes for electronic products can be included into those sources.

Introduction. The authors investigate the problem of discrepancy between regulations imposed by Federal state educational and professional standards and professional values and beliefs significant for modern educators. The aim of this article is to define and clarify value-based frameworks from the point of view of modern socio- professional teacher’ community. Materials and Methods. Methodological basis of the present research is a system approach connected with the concept of systemogenesis of the activity, designed by academician V. D. Shadrikov. Adopting the systemogenesis approach to academic research, the authors employed methods of morphological and psychological analysis of teaching and the method of operationalization of existing educational and professional standards, regulating the requirements for the level of teacher education and teacher functions. Empirical data were collected via a questionnaire developed by the authors. In order to process the obtained data, the methods of initial descriptive statistics, correlation, systemic-structural and factor analysis were applied. Results. The research findings show the most important instrumental values for teachers which are closely connected with value-based aims of such categories as ‘child’, ‘environment’ and ‘profession’. The analysis of empirical data highlighted such significant values as ‘profession’, ‘environment’, and ‘child’. The common structure of teachers’ instrumental values consists in significant quality-centered values, less important knowledge-centered values and the least important relationship-centered ones. Therefore, the authors have identified the predominance of external professional values for modern educators. It contradicts the educational standards which emphasize learner-centered approach and focus on fulfilling learners’ potential. Conclusions. The study concludes that socio-professional community of modern teachers does not consider the child as the main priority of teaching. Instead, they emphasize the values of ‘profession’ and ‘environment’.

Introduction. Purchasing power of national currency varies widely across countries and regions, thus inter-regional comparisons pose a problem of financial and economic indicators comparability. In Russia, this issue is being currently solved by using the state budget expenditures index and the cost of a fixed set of goods and services (consumer basket) calculated for each region. The aim of this article is to propose and evaluate an alternative method of improving the accuracy of inter-regional price differentiation estimates. Materials and Methods. This study is based on the research investigation by Costa et al (2019) conducted on a sample of more than 300 regions of OECD countries. Relying on that research, the authors collected relevant data on Russian regions and analyzed a multiple linear regression model. Within the model, a consumer basket cost was a dependent variable, and the average income, the share of industry and the share of services in gross regional product were considered as independent variables. Results. The parameters of the model revealed an acceptable level of its explanatory power (R2 = 0.76), as well as a significant influence of all factors. Applying the model, the authors received the predicted consumer basket cost. Both types of the consumer basket costs (actual and predicted) were correlated with the external factors of regional price differentiation, selected from the literature as evaluation criteria: transport infrastructure quality, social inequality level, market competition level, regional fiscal policy, etc. The analysis revealed that significant correlations with the external parameters were higher for the predicted consumer basket cost as compared to the actual one. The possibility of using the results of this study to improve the accuracy of the comparative interregional analysis of financial and economic indicators is illustrated by the example of comparing the nominal and calculated adjusted values of teachers’ average salary in all regions of the Russian Federation. Conclusions. The findings suggest that the predicted consumer basket cost allows to conduct more accurate assessment of the differences in the national currency purchasing power in Russian regions. The results of the study can be used to improve the accuracy in comparative inter-regional investigations of financial and economic indicators.

Published: October 2021

Introduction. The article summarizes the results of studying the process of students’ adaptation to the learning environment in a wide range of degree programmes provided by higher educational institutions. The purpose of the article is to identify the characteristic features of students’ psychophysiological adaptation to the learning environment, taking into account the peculiarities of autonomic regulation, with the subsequent assessment of the effectiveness of using RSA-BFB therapy. Materials and Methods. The study involved 209 second-year medical and biological students. The study of neurodynamic characteristics was carried out using an automated psychophysiological complex. Heart rate variability indicators were evaluated by means of cardiorhythmography. The authors conducted a comparative analysis of the mean values and identified the correlation between neurodynamic characteristics and indicators of heart rate variability of students doing academic degrees in various fields. RSA-BFB therapy was used to increase students’ adaptive capabilities. Results. The characteristic features of adaptive reactions were revealed depending on the initial vegetative tone and the type of functional response. The combination of psychophysiological and medico-biological constitutional approaches used in the work enabled the authors to expand and clarify the ideas about the mechanism of the functional self-regulation system and classify the types of adaptive reactions in the process of educational: adaptive, compensatory and maladaptive. After the RSA-BFB therapy for students prone to maladaptive reactions, in comparison with the control group, there was an improvement in the strength of the nervous system and the mobility of nervous processes. Using RSA-BFB therapy contributed to overcoming chronic stress and developing reaction patterns inherent in adaptive types. Conclusions. The use of RSA-biofeedback therapy, taking into account the individual-typological characteristics, has contributed to balancing ergotropic and trophotropic processes, restoring the body's functional reserves and improving the efficiency of adaptation to learning environment.

Introduction. The problem of developing clear criteria for assessing athletes’ functional fitness, which would reflect their readiness for competitions, remains under-researched in the theory of sports. Football places high demands on athletes’ functional fitness, including the vegetative component. However, attempts to improve results in football often focus on techniques and tactics to the detriment of the functional component. It should also be noted that the intensity of exercises varies depending on the playing position during matches, and, therefore, an accurate diagnostic criterion is required to assess the players’ of different positions functional readiness for competitions. The article attempts to identify the parameters of heart rate variability which could be used as markers of athletes’ playing game sports high functional performance. The aim of this research is to identify the parameters of heart rate variability as a diagnostic criterion for assessing football players’ functional readiness for competitions. Materials and Methods. In order to assess the heart rate variability, the software for the “Polyspectrum” electrocardiograph was used with an additional function of obtaining data on heart rate variability. Results. The research findings suggest that football players with high athletic performance demonstrate higher vagal and lower sympathetic modulation of the heart rhythm, which indicates their higher fitness, adaptability to loads and functional readiness for competitions. On the contrary, the athletes of the second group demonstrated signs of strain of adaptation systems and over-training. Conclusions. Monitoring heart rate variability in athletes (in particular, heart rhythm wave structure indicators, expressed as the area of the triangle formed by the spectral density of all three waves) can be used as an effective tool in the dynamic control of training, in identifying athletes’ fitness, as well as for predicting sports results.
Fenced community gardens effectively mitigate the negative impacts of white-tailed deer on household food security
Authors: Manning Paul
Published: October 2021

White-tailed deer (Odocoileus virginianus) are large herbivores that thrive in urban and peri-urban landscapes. Their voracious appetite and ubiquity have made deer a significant threat to growing food in home and community gardens; features that often make important contributions towards household food security. Focusing on food availability, stability, utilization, and access, I outline how white-tailed deer threaten household food security. Deer threaten availability of food by widely consuming plants grown for human consumption. Deer threaten stability of household food security by causing spatially and temporally unpredictable food losses. Deer threaten utilization of food, through acting as sources of food-borne pathogens (i.e. Escherichia coli O157:S7). Deer threaten access to food by necessitating relatively high-cost economic interventions to protect plants from browsing. Although numerous products are commercially available to deter deer via behavioural modification induced by olfaction and sound – evidence of efficacy is mixed. Physical barriers can be highly effective for reducing deer browsing, but often come with a high economic cost. Users of community gardens benefit from fencing by receiving shared protection against deer herbivory at a significantly lower per capita cost. Among many other benefits, fenced community gardens are useful in mitigating the threats of white-tailed deer to household food security.
Unboxing the bento box: An arts-informed inquiry into Japanese families’ experience at Canadian school lunch time
Authors: Seko Yukari , Rahouma Lina , Takano Reeves Chie , Wong Veen
Published: October 2021

Bento, a Japanese style boxed lunch, has a distinct cultural meaning for Japanese people as a medium of affective communication between children and parents. However, in Canadian schools governed by the Anglo-Western food norms, their culinary practices may stand out. This study employed an arts-informed participatory design to explore how school-aged children (6-12 years old) of Japanese origin and their parents describe their experience bringing Japanese food to school in Canada. We conducted arts-informed workshops with 16 children who created artworks about their lunchboxes, and focus groups with 19 parents (all mothers). Children’s artworks illuminated a common aesthetics about “good” lunch that closely reflected mothers’ commitment to preparing nutritionally balanced and aesthetically appealing bento boxes. Both children and mothers reported that Canadian school food environment (e.g., short eating periods, snack times, built environment) sometimes misaligns with their food practices. Some families were compelled to modify their bento to accommodate children’s needs to fit in at school. Meantime, participants’ narratives indicate the prevalence of stigma toward “junk” food that may perpetuate food shaming at school. A more inclusive, diverse and culturally appropriate discussion on “healthy eating” at school can embrace children’s and their families’ intercultural food identities.

Published: October 2021

Wayne Roberts (1944–2021) was a food systems thinker, public intellectual, and “actionist.” This text was developed from a series of oral history interviews conducted between December 2020 and January 2021. It touches upon several of the key themes Wayne addressed during the interviews: adopting a food systems approach; employing the power of ideas; identifying solutions and being propositional; acknowledging progress for political credit; enhancing impact through media, old and new; working strategically to “seed” then “tip”; playing ball to influence government; and, forming alliances with academics and other champions. In addition, we provide selected links to additional resources from Wayne himself. In this article, which inaugurates the Interviews section of Canadian Food Studies/La Revue canadienne des études sur l’alimentation, we aim to do justice to the gift of Wayne’s experiences and knowledge by sharing a selection and synthesis of his words.

On the approximation properties of bi-parametric potential-type integral operators
Authors: SEKİN Çağla , GÜLOĞLU Mutlu , ALİYEV İlham
Published: October 2021

In this work we study the approximation properties of the classical Riesz potentials $I^{\alpha }f\equiv (-\Delta )^{-\alpha /2}f$ and the so-called bi-parametric potential-type operators $J_{\beta }^{\alpha }f\equiv(E+(-\Delta )^{\beta /2})^{-\alpha /\beta }f$ as $\alpha \rightarrow \alpha_{0}>0$ where, $\alpha >0$, $\beta >0$, $E$ is the identity operator and $\Delta $ is the laplacian. These potential-type operators generalize the famous Bessel potentials when $\beta =2$ and Flett potentials when $\beta =1$. We show that, if $A^{\alpha}$ is one of operators $J_{\beta }^{\alpha }$ or $I^{\alpha}$, then at every Lebesgue point of $f\in L_{p}(\mathbb{R}^{n})$ the asymptotic equality $(A^{\alpha}f)(x)-(A^{\alpha _{0}}f)(x)=O(1)(\alpha-\alpha _{0})$, ($\alpha \rightarrow \alpha _{0}^{+}$) holds. Also the asymptotic equality $\left\Vert A^{\alpha }f-A^{\alpha _{0}}f\right\Vert_{p}=O(1)(\alpha -\alpha _{0})$, ($\alpha \rightarrow \alpha _{0}^{+}$) holds when $A^{\alpha}=J_{\beta }^{\alpha }$.
A note on induced connections
Authors: KADAOUİ ABBASSİ Mohamed Tahar , LAKRİNİ Ibrahim
Published: October 2021

In this note, we will exploit the classical bijective correspondence between sections of an associated vector bundle and equivariant functions on the underlying principal bundle to revisit a global formula for induced connections on associated vector bundles. Consequently, we give the expression of the curvature in terms of the curvature 2-form of a connection on a principal bundle.
On the covering radii of a class of binary primitive cyclic codes
Authors: TUTDERE Seher
Published: October 2021

In 2019, Kavut and Tutdere proved that the covering radii of a class of primitive binary cyclic codes with minimum distance greater than or equal to $r+2$ is $r$, where $r$ is an odd integer, under some assumptions. We here show that the covering radii $R$ of a class of primitive binary cyclic codes with minimum distance strictly greater than $\ell$ satisfy $r\leq R \leq \ell$, where $\ell,r$ are some integers, with $\ell$ being odd, depending on the given code. This new class of cyclic codes covers that of Kavut and Tutdere.

Authors: KİŞİ İlim
Published: October 2021

In this paper, we handle focal surfaces of surface of revolution in Galilean 3-space $\mathbb{G}_{3}$. We define the focal surfaces of surface of revolution and we obtain some results for these types of surfaces to become flat and minimal. Also, by giving some examples to these surfaces, we present the visualizations of each type of focal surface of surface of revolution in $\mathbb{G}_{3}$.
Intervention effects in clefts: a study in quantitative computational syntax
Authors: Samo Giuseppe , Merlo Paola
Published: October 2021

Clefts are understood as biclausal structures involving the movement of a clefted constituent from a lower clause, where it is generated, to a higher clause, where it is interpreted. Though both grammatical, subject and object clefts show signs of different acceptability in experimental settings. This degradation is ascribed to the fact that the object needs to cross an intervening subject, thus triggering intervention effects. In this paper, we show that intervention effects are also present in grammatical configurations, and give rise to lower-than-expected frequencies. Based on sets of features that play a role in the syntactic computation of locality, we compare the theoretically expected and the actually observed counts of features in a corpus of thirteen syntactically annotated treebanks for three languages (English, French, Italian). We find the quantitative effects predicted by the theory of intervention locality: object clefts are less frequent than expected in intervention configuration, while subject clefts are roughly as frequent as expected. We also find that the size of the effect is proportional to the number of features that give rise to the intervention effect. These results provide a three-fold contribution. First, they extend the empirical evidence in favour of the feature-based intervention theory of locality. Second, they provide theory-driven quantitative evidence, thus extending in a novel way the sources of evidence used to adjudicate theories. Finally, the paper provides a blueprint for future theory-driven quantitative investigations.
Utopian Montage: exploring transnational folk cinemas online during the Covid-19 pandemic as part of the 2020 Folk Film Gathering film festival
Authors: Chambers Jamie , Higbee Will
Published: October 2021

This essay explores some of the simultaneous limitations and affordances the Covid-19 pandemic has created for emergent perspectives upon a transnational folk cinema. Merging aspects of more traditional scholarly enquiry with the research-by-practice embodied within Scotland's Folk Film Gathering film festival, we position two case studies - of Nadir Bouhmouch's Amussu (2020) and the Amber Collective's Like Father (2001) respectively - within some of the broader question underlying attempts to bring the conviviality of community-focussed filmmaking and cinema-going online during the pandemic.
COVID-19 PANDEMİSİNDE GELİŞMEKTE OLAN ÜLKELERİN SOSYAL KORUMA ÖNLEMLERİ ÜZERİNE BİR ANALİZ
Authors: SEÇKİNER BİNGÖL Ezgi
Published: October 2021

Bu çalışmada gelişmekte olan ülkelerde Covid-19 pandemisi süresince uygulanan sosyal koruma önlemleri üzerine bir analiz gerçekleştirilmiştir. Gelişmekte olan ülkelerde pandemi benzeri bir krizde kapsamlı sosyal koruma sağlayan politi-kaların ne olduğu sorusuna yanıt aranmıştır. İlk olarak, Uluslararası Çalışma Örgütü’nün (ILO) işsizlik yardımı verileri ve Dünya Bankası’nın (WB) gelişmekte olan ülkelerin sosyal güvenlik önlemlerine ilişkin Dayanıklılık ve Eşitlik Sosyal Koruma Göstergeleri Atlası (ASPIRE Index) verileri kullanılarak gelişmekte olan ülkelerin sosyal koruma önlemlerine genel bir bakış sunulmuştur. İkinci olarak, Ekonomik İşbirliği ve Kalkınma Örgütü’nün (OECD) Koronavirüsle Mücadelede Politika Önlemleri raporlarındaki verilerden yararlanılarak 15 gelişmekte olan ülke örneğinin pandemi süresince uyguladığı sosyal koruma önlemleri analiz edilmiştir. Gelişmekte olan ülkelerin işsizlik sigortası kapsamı, kayıt dışılık, sosyal sigorta ve sosyal yardımların kapsamı ve erişilebilirliği konularında bazı ortak problemlere sahip olduğu görülmüştür. Pandemi süresince uygulanan sosyal koruma önlemleri ise çoğunlukla mevcut nakit transferin devamsız olarak genişletilmesi, sosyal koruma programlarının kapsamına girmeyen savunmasız kişilere ulaşmak için ek transferler gerçekleştirilmesi gibi geçici tedbirler içermektedir. Çalışma sonucunda bu problemlere yönelik kapsamlı sosyal koruma sağlayabilecek bazı politika önerileri geliştirilmiştir.
Associativism and extensionism: a proposal for ecotourism and reproduction of productive backyards Caratateua island, Belém–PA
Authors: Oliveira Rita Denize de , Silva José Augusto Lopes da
Published: October 2021

Caratateua Island comprises the insular portion of the metropolitan region of Belém-Pará. Despite the historical abandonment of the State, demonstrated in the low level of basic sanitation and difficulties in the supply of potable water and a precarious sewage network, limited availability of high schools and only one health center to serve the people of the island, the place ends up being a refuge for the population excluded by urban reform projects, such as the macro-drainage of the hydrographic basins of Belém, for example, in addition to receiving families who migrate from other interior cities and Ilha do Marajó. However, the island is reference for Environmental Education, through sustainable practices dissemination by the Fundação Escola Bosque Professor Eidorfe Moreira, housing popular cultural events such “cordão de pássaros juninos” and “boi bumbá” and festivals such as “Círio de Nossa Senhora da Conceição” and festivities of Iemanjá. Another specificity of the island is a strong political activism that manifests itself in the formation of associations with different purposes, from religious freedom, ancestry, valorization of rites and recovery of knowledge, to purposes involving human rights, rehabilitation, reintegration into the market for disabled people, agroecology, local development and food security as proposed by the Beneficent Association of Disabled and Reduced Mobility People of Pará, which constitutes a proposition to face the post-pandemic crisis in insular areas and is the main theme of this article.
Environmental Acoustic Comfort in the Built Environment

Published: October 2021

The acoustic quality of classrooms has a strong influence on the teaching and learning process. This interference assessed using the impulsive technique to measure the rate of speech transmission (STI), reverberation time (RT) and sound definition (D50). These are the most relevant acoustic descriptors in the assessment of classrooms, where verbal exposure is the means of communication between teachers and students. The evaluation took place in two buildings of the Federal University of Paraná (UFPR), built in the 1960s and another in 2016. The measured values ​​of STI, provided in the classrooms' actual acoustic conditions, were used as an adjustment parameter for simulations made with the software ODEON. After carrying out the measurements and simulations, the dimensioning of improvements was possible. The acoustic simulations presented suggestions to qualify the quality of the classrooms' acoustic comfort, ensuring that teaching and learning to do not suffer losses due to the physical structure of the classrooms. The measured values ​​of STI, RT and D50 show that, in the old building, except for a single classroom that preserves the original ceiling that had a high sound absorption coefficient, it has reasonable values, below the ideal for classrooms, according to the IEC 60268-16 (2011) standard. The investigation showed that the rooms with a roof replaced by a PVC covering had a sharp drop in acoustic quality. The newest building has classrooms with proper acoustic comfort conditions.

Published: October 2021

The present study aims to study environmental noise pollution in areas close to the northern stretch of the Green Line, in Curitiba, PR, Brazil, which has a length of approximately 8 km. For this purpose, in situ measurements of sound levels were carried out and noise pollution was evaluated through the calculation of noise maps in addition to acoustic simulations. Measurements were recorded at 16 points following the guidelines of the NBR 10151. Acoustic maps were made for each point using proper acoustic software. The aim was to verify whether measured values were within a margin error of up to 4.6 dB(A) compared to simulated values. After validating the maps and verifying the noise pollution at the selected points, one of the points, which is close to a hospital, was analyzed alone to evaluate different simulation scenarios. The selected scenarios were replacement of common asphalt for one with porous properties; 90% restriction on the quantity of heavy vehicles; reduction of average speed of vehicles from 80 km/h to 60 km/h; 50% restriction on the number of vehicles of all categories; and acoustic situation of the site, including all the measurements proposed in the previous scenarios. All scenarios presented in this work reveal that the measurements adopted were not sufficient to reach 55 dB(A) near sensitive areas such as hospitals. They also show that just one control measure is not enough to lower noise efficiently. A plan with several joint measures is needed to alleviate the problem.
