Optimal humanitarian warehouses location considering vulnerability previous condition
Authors: Chipana-Surquislla Wendy Cerlubia , Cornejo-Sanchez Christian , Vargas-Florez Jorge
Published: April 2022

Goal: This study tackles on location problem, analyzing the urban shape base on vulnerability previous conditions in affected areas.
Design / Methodology / Approach: A numerical analysis is performed using an integer programming model to find optimal preposition warehouses location.
Results: The minimum cost is reached when the needs of all the people affected by the natural disaster are met. Excess construction of warehouses implies additional maintenance and administration expenses, while lack of construction of warehouses implies expenses originated by unsatisfied demand.
Limitations of the investigation: Among the main limitations found in this study were the lack of updated data and few studies related to natural disaster prevention in the case study.
Practical implications: Organizations should implement the recommendations given by the new model. This is because the model minimizes the cost, since the damage caused by a natural disaster is much more expensive than preventing it.
Originality / Value: The novelty in this study is the creation of a punishment factor based on the level of vulnerability of the routes used in transportation. This is to simulate the impact the deterioration of routes has on the response time of sending aid supplies.

Abstract. The purpose of the study is to develop an automated system for technical diagnostics of the state and regu-lation of the electric drive of the rollers of the collector roller table at a wide hot rolling mill based on change in the load currents of the rollers electric motors. The system allows the quality of finished rolled products and the produc-tivity of the mill to be enhanced due to the timely detection of faulty equipment and its rapid replacement based on the results of diagnostics. The following methods of diagnostics of the electric drive of the diverting roller table and its possible malfunctions which can negatively affect the quality of the finished rolled products were analyzed: experimental identification of the relation of the forms of change in the load currents of the electric motors of the rollers with specific types of malfunctions; determination of diagnostic signs of malfunctions in the values of change in the load currents of the electric motors of the rollers; creation of a mathematical model for calculating the forces of strip transportation; develop-ment of methods and algorithms for technical diagnostics of the electric drive of the collector roller table based on charac-teristics of change in the load currents of the electric motors of the rollers; development of a generalized algorithm for the operation of the automated technical diagnostics system; experimental evaluation of the effectiveness of the proposed methods and algorithms for diagnostics on the operating mill. Analytical methods of solving algebraic and differential equations and systems were used in the study. As a result of the research, the technical effectiveness of the methods and algorithms developed to diagnose the eccentricity of the roller barrel of the diverting roller table, malfunctioning of the brush-collector device of the roller electric motor, the destruction of the couplings in the roller electric drive line, malfunc-tioning of the bearing units in the roller electric drive line or the roller sides, the correct alignment of the roller relative to the technological plane of the diverting roller was experimentally confirmed. The diagnostic methods and algorithms de-veloped can be used to create diagnostic systems for electric drives of diverting roller table at operating mills during their reconstruction, as well as at newly built mills. The system thus developed was installed at the industrial plant's 2000 hot rolling mill.

Angel Oak Academy, London, England
Authors: MacKechnie Charlotte
Published: April 2022

Angel Oak Academy is a two-form entry mainstream primary school in
Peckham, South East London. Students are from a wide range of minority
ethnic backgrounds; 55% speak English as an Additional Language (EAL), and
many enter school at an early stage of learning English. A large majority of
students are supported by additional government funding, including 47.2% of
411 students currently on roll qualifying as eligible for free school meals
(compared to a national average of 23% across mainstream primary schools in
England). The predecessor school became an academy within the STEP Academy
Trust (a charitable trust with schools in areas of high social deprivation)
in February 2015. In September 2015, following a recommendation from a STEP
trustee, Angel Oak Academy began the process of implementing
Sounds-Write.
Bloomfield Learning Centre, London, England
Authors: Horner Sarah , Orr Jane
Published: April 2022

The Bloomfield Learning Centre (BLC) is a specialist literacy clinic, in
Southwark, London. It provides diagnostic assessments and one-to-one
teaching for children, aged from seven years to young adults, who are
failing at school or unable to partake in further education, due to their
inability to read and write fluently. The BLC teaches 84 students per week.
The BLC works primarily with students from socially deprived inner London
boroughs. Their parents lack the funds to pay for tutoring and their schools
struggle to provide the one-to-one teaching they need. These young people
are thus deprived of educational opportunities. At the time of writing,
3.75% of students speak English as a second language. The BLC is a charity,
with no statutory funding. All Sounds-Write lessons are subsidised and 15%
of students have full bursaries. Some schools and some parents contribute
towards the cost of lessons. The BLC is reliant on donations to cover the
budget shortfall. Students are referred to the BLC primarily by schools or
parents, but occasionally by other professionals. During the Covid-19
pandemic, whilst schools were open only to the children of key workers, the
usual ratio of school (65%) and parent (35%) referrals changed dramatically.
Between June 2020 and July 2021, 6% of students were referred by schools and
94% by parents.

Ysgol Merllyn (Merllyn Community Primary School) is located in the
village of Bagillt in North Wales (UK), an old lead-mining village in a
semi-rural location. It is a state primary with 150 students aged three to
eleven, of which 26% are entitled to free school meals and 12% have English
as an Additional Language (EAL). Transiency is 8% and 12% of students have
Additional Learning Needs (ALN), including 8% with behavioral needs. The
school had previously taught the infants (aged four to seven) using a
synthetic phonics programme, however, there were many children coming
through the infants who still did not have a secure knowledge of
sound-spelling correspondences, and were not able to segment, blend, and
manipulate phonemes. Many children in the juniors required intervention due
to poor reading and decoding skills.

Authors: Hammond Kendall
Published: April 2022

Nollamara Primary and Intensive English School (NPS) is situated seven
kilometers north of the Perth Central Business District in Western
Australia. Our Index of Community Socio-Educational Advantage (ICSEA) is 939
and the school caters for students from Kindergarten to Year 6. There are
currently 309 students who are supported by 50 staff. NPS was opened in 1956
and an Intensive English Center (IEC), supporting newly arrived humanitarian
and refugee students, commenced in 2005. The school has a diverse population
(see Figure 1), and there are more than 76% of students with a language
background other than English at the school, with approximately 45 language
groups. The larger groups include Arabic 13%, Dinka 7%, Karen 4.5%, and
Burmese, Swahili, Vietnamese, and Kirundi which combined represent 10% of
the cohort. Aboriginal students make up 8% of our school community. There is
a high transiency rate at NPS, approximately 51%. This is due to the
students in the IEC returning to their local school after one to two years
on specialist English language intervention. Many families are in temporary
or rental accommodation, which impacts on student enrollment, too. The
school has a full-time chaplain, school psychologist (two and a half days a
week), two Aboriginal Islander Education Officers (AIEO), and two
multicultural liaison officers who support students and families as well as
engage local agencies. The school also provides intervention with trauma
counseling, speech therapists, and occupational therapists.

“Make them come in, so that my house may be filled” (Lk 14:23): Church building as a chance Church pedagogy aims at acquainting various groups of people (respecting their ages or interests) with the inside of the church by means of holistic and experiential learning. Other aims include: Perceiving the church as a place for religious studies; enabling people enter into dialogue with the religious tradition through the church building, through meetings in it and through experience; teaching the Christian alphabet by reading the church inside; discovering the church using all senses; making oneself at home in the church. Church pedagogy may be one of the methods which Churches can use to translate the Christian faith to their contemporaries in the present multicultural society.
Kdo je vlastně kaplan? Nástin teologické typologie v současném společenském kontextu
Authors: Hájek Matěj
Published: April 2022

Who is chaplain after all? Towards a theological typology of chaplaincy in contemporary social-cultural context The following article is a contribution to a responsible theological reflection on chaplaincy. The operation of chaplains is considered as a specific and intentionally focused way of spiritual ministry. Unlike the pastoral ministry in the church community, the chaplain ministry is located in the institutions of different public services. The spiritual care provided by a concrete chaplain is therefore being created and negotiated in the ongoing dialogue with the concrete social sphere where the very chaplain is active. What theological position brings the chaplain with her towards this vivid dialogue? What is the theological frame in which the chaplain can operate? Following the official mind setting church documents on missiological approach in contemporary society, we formulated four different types of theological perspective on chaplain ministry. The typology was structured with help of a hermeneutical tool brought by H. R. Niebuhr in his classics „Christ and Culture“. Niebuhr’s typology helped to organize and frame the leading 4 different approaches towards mission and chaplaincy. At the end of the day it helps to design a theological scale on which the concrete Christian traditions view the chaplain’s identity and their ministry.

Žilka followed the call to become a faculty professor after some 23 years in the service of a church minister, and with a systematic plan of basic publications he laid the foundations of the New Testament studies. A major achievement of lasting value is his modern translation of the New Testament, he is also remebered as a learned and both gentle and determined proponent of liberal protestantism in the Czech church environment.
Simultaneity in the Scientific Enterprise
Authors: Sarafoglou Nikias , Kafatos Menas , Beall John H.
Published: April 2022

In this article, we explore the concept of simultaneity in the scientific enterprise, defined herein as the near-coincident discovery of significant advances in the development of our scientific understanding of the world. We do this by examining two case studies of such coincident or near-coincident discoveries: the development of the so-called Lorentz transformation by H.A. Lorentz (1904) and A. Einstein (1905); and the Aharonov-Bohm effect discovered independently in chronological order by Franz(1939), Ehrenberg and Siday (1949) and Aharonov and Bohm (1959). It is now generally acknowledged that the Lorentz transformations were independently developed by both Lorentz and Einstein as they worked on different approaches to solve a similar problem – i.e., the preservation of the form of Maxwell's equations in coordinate systems moving relative to one another, while the relationship between the Ehrenberg-Siday and Aharonov-Bohm works is still controversial. In our view, these independent discoveries allow some speculation about the nature of human discovery and understanding of scientific truths as they progress through time.
Challenges Affecting the Implementation of Decentralisation in Public Basic Schools in Ghana
Authors: Kyeremeh Alex , Kor Jacob Aaworb-nang Maabobr
Published: April 2022

Educational management is a major element that produces successful educational outcomes. Over the years decentralisation has become one major policy for effective and efficient educational management in public basic schools in Ghana. Decentralisation entails the transfer of administrative and fiscal authority to the grassroot where management decisions prickly taken for effective management. This study sought to investigate challenges mitigating the implementation of decentralisation in public basic schools in Ghana. Among some key challenges faced were inadequate logistics for key stakeholders to carry out their functions. Again, there are limited support for infrastructure from both local and governmental levels. There are inadequate and delay in supply of teaching and learning materials. Delay in decision on appointments, promotions and sanction of errant staff. Political interference by government appointees also affects implementation of effective decentralisation. Difficulty in monitoring and supervise some schools due to bad roads in deprived communities also have adverse effect on the implementation of decentralisation. It was recommended devolution policy to replace the existing decentralisation policy in public basic schools for the full benefit of decentralisation. This will make it possible for major decisions like appointments, promotions and disciplinary actions taken at grassroot level instead of the centre. Logistics and TLM must get to schools on time for effective management of school.

Stosunek prawny jako podstawa wyłączenia pracownika w postępowaniu administracyjnym
Authors: Paduch Andrzej
Published: April 2022

Artykuł porusza problem wyłączenia pracownika organu od udziału w postępowaniu administracyjnym w sytuacji, w której pomiędzy nim a stroną zachodzi stosunek prawny tego rodzaju, że wynik sprawy może mieć wpływ na prawa i obowiązki pracownika (art. 24 § 1 in fine k.p.a.). Do wyłączenie dochodzi wówczas  z mocy prawa i jest podyktowane dążeniem do załatwiania spraw administracyjnych z uwzględnieniem wymogu bezstronności pracownika. Konstrukcja omawianej przesłanki opiera się na dwóch elementach. Po pierwsze, do wyłączenia na podstawie wskazywanego przepisu dochodzi jedynie wtedy, gdy stronę i pracownika łączy stosunek prawny. Analizowana podstawa wyłączenia nie zachodzi zatem wtedy, gdy stosunek ten ma charakter jedynie faktyczny lub np. gdy istniał w przeszłości. Po drugie, stosunek ten musi charakteryzować się swoistą relacją pomiędzy wynikiem sprawy a zakresem praw lub obowiązków pracownika – mogą one ulec modyfikacji przy określonym rozstrzygnięciu.  Wyłączenie pracownika na podstawie omawianej przesłanki wydaje się niezwykle złożone: obie ze wskazanych przesłanek muszą wystąpić łącznie, przy czym mają one charakter ocenny. Z tej przyczyny autor proponuje wykreślenie z k.p.a. omawianej podstawy wyłączenia pracownika oraz objęcie uregulowanych w niej przypadków wyłączeniem na wniosek (art. 24 § 3 k.p.a.). Będzie to zgodne z zasadami: szybkości postępowania, budzenia zaufania uczestników postępowania do władzy publicznej oraz legalizmu.
Popularity prediction for social media over arbitrary time horizons
Authors: Haimovich Daniel , Karamshuk Dima , Leeper Thomas J. , Riabenko Evgeniy , Vojnovic Milan
Published: April 2022

Predicting the popularity of social media content in real time requires approaches that efficiently operate at global scale. Popularity prediction is important for many applications, including detection of harmful viral content to enable timely content moderation. The prediction task is difficult because views result from interactions between user interests, content features, resharing, feed ranking, and network structure. We consider the problem of accurately predicting popularity both at any given prediction time since a content item's creation and for arbitrary time horizons into the future. In order to achieve high accuracy for different prediction time horizons, it is essential for models to use static features (of content and user) as well as observed popularity growth up to prediction time.

We propose a feature-based approach based on a self-excited Hawkes point process model, which involves prediction of the content's popularity at one or more reference horizons in tandem with a point predictor of an effective growth parameter that reflects the timescale of popularity growth. This results in a highly scalable method for popularity prediction over arbitrary prediction time horizons that also achieves a high degree of accuracy, compared to several leading baselines, on a dataset of public page content on Facebook over a two-month period, covering billions of content views and hundreds of thousands of distinct content items. The model has shown competitive prediction accuracy against a strong baseline that consists of separately trained models for specific prediction time horizons.
Database workload characterization with query plan encoders
Authors: Paul Debjyoti , Cao Jie , Li Feifei , Srikumar Vivek
Published: April 2022

Smart databases are adopting artificial intelligence (AI) technologies to achieve
instance optimality
, and in the future, databases will come with prepackaged AI models within their core components. The reason is that every database runs on different workloads, demands specific resources, and settings to achieve optimal performance. It prompts the necessity to understand workloads running in the system along with their features comprehensively, which we dub as workload characterization.

To address this workload characterization problem, we propose our query plan encoders that learn essential features and their correlations from query plans. Our pretrained encoders captures the structural and the
computational performance
of queries independently. We show that our pretrained encoders are adaptable to workloads that expedites the transfer learning process. We performed independent assessments of structural encoder and performance encoders with multiple downstream tasks. For the overall evaluation of our query plan encoders, we architect two downstream tasks (i) query latency prediction and (ii) query classification. These tasks show the importance of feature-based workload characterization. We also performed extensive experiments on individual encoders to verify the effectiveness of representation learning, and domain adaptability.
Real-time recognition of different imagined actions on the same side of a single limb based on the fNIRS correlation coefficient
Authors: Fu Yunfa , Wang Fan , Li Yu , Gong Anmin , Qian Qian , Su Lei , Zhao Lei
Published: April 2022

Functional near-infrared spectroscopy (fNIRS) is a type of functional brain imaging. Brain-computer interfaces (BCIs) based on fNIRS have recently been implemented. Most existing fNIRS-BCI studies have involved off-line analyses, but few studies used online performance testing. Furthermore, existing online fNIRS-BCI experimental paradigms have not yet carried out studies using different imagined movements of the same side of a single limb. In the present study, a real-time fNIRS-BCI system was constructed to identify two imagined movements of the same side of a single limb (right forearm and right hand). Ten healthy subjects were recruited and fNIRS signal was collected and real-time analyzed with two imagined movements (leftward movement involving the right forearm and right-hand clenching). In addition to the mean and slope features of fNIRS signals, the correlation coefficient between fNIRS signals induced by different imagined actions was extracted. A support vector machine (SVM) was used to classify the imagined actions. The average accuracy of real-time classification of the two imagined movements was 72.25 ± 0.004%. The findings suggest that different imagined movements on the same side of a single limb can be recognized real-time based on fNIRS, which may help to further guide the practical application of online fNIRS-BCIs.

Physical Organic Chemistry in the 21st Century: A Q1 Progress Report
Authors: Williams Ian H.
Published: April 2022

In 1997, a collection of twenty personal perspectives from eminent chemists was published in Pure and Applied Chemistry to mark the centenary of physical organic chemistry [1]. This Symposium in Print, entitled Physical Organic Chemistry in the 21st Century (POC21C), was organized by the IUPAC Commission on Physical Organic Chemistry, which was chaired at that time by Tom Tidwell, who contributed a historical prologue in which he suggested Stieglitz’s 1899 proposal of carbocations as reaction intermediates as (unwittingly) having given birth to the discipline. The principal authors were Edward Arnett, Daniel Bellus, Ron Breslow, Fulvio Cacace, Jan Engberts, Marye Anne Fox, Ken Houk, Keith Ingold, Alan Katritzky, Ed Kosower, Meir Lahav, Teruaki Mukaiyama, Oleg Nefedov, George Olah, John Roberts, Jean-Michel Savéant, Helmut Schwarz, Andrew Streitwieser, Frank Westheimer, and Akio Yamamoto. Tidwell noted that, whereas they were not all known as physical organic chemists, yet they had all used the tools of this discipline in their work and were able to comment upon the utility of physical organic chemistry for the practice of other areas of chemistry as well. The theme that ran through all the essays was that the future of the field lay in an interdisciplinary approach, that physical organic chemists would use all the tools available to them, and that they would not be fettered to narrow views.
Three Years with Coman: How Much Has Changed?
Authors: Křičková Lenka
Published: April 2022

In 2018, the ECJ ruled in its landmark Coman judgment (C-673/16) that same-sex spouses of EU citizens exercising their freedom of movement must be granted a right of residence even in Member States that do not recognize same-sex marriages. Looking back on the judgment after 3 years, this article reviews the academic reactions which ranged from criticism to celebration of the judgment. Using the example of the Czech Republic, it then assesses the judgment’s practical impact to see whether the initial expectations regarding future development came true, and identifies potential barriers in the national law that could still hinder free movement of same-sex couples. Finally, the article discusses what lessons can be learnt from the Coman judgment for other similar cases before the ECJ, especially those concerning the status of children born to same-sex couples.

The article argues that there have been no noticeable changes in Czech law ascribable to the Coman judgment. This suggests that beyond the narrow holding strengthening the same-sex couples’ residence rights, though symbolically and practically important, possible greater impact of the Coman case on Member States’ national law should not be overestimated. However, the judgment’s significance lies in its potential to shape the future ECJ’s case-law because the free movement framework used in Coman can be similarly applied to cross-border recognition of same-sex couples and families for other purposes than residence rights. If the ECJ does so in the upcoming cases and properly tackles the Member States’ national identity or public policy objections, further developments of gay rights through EU law might take place.
Experimental and computational study of fluidized-microwave drying process of shrinking parchment coffee and determination of quality attributes
Authors: Reyes Chaparro Jose , Durán Barón Ricardo , Valle Vargas Marcelo , Arballo Javier Ramiro , Campañone Laura Analia
Published: April 2022

This work presents the fluidized bed drying process combined with microwaves applied to Parchment coffee. In order to study different parameters that affect the quality of the grains, a mathematical model that describes energy and mass transfer during the drying process is presented and solved using Finite Elements Method (FEM) through COMSOL Multiphysics software. The model also considered the shrinkage of the grains due to water removal. Experiments were carried out in experimental prototype equipment obtaining the drying curves, which were utilized to validate the mathematical model. To study the impact of the operating conditions on the quality of the processed coffee, total polyphenolic content and antioxidant capacity were determined by Folin-Ciocalteau and free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) methods, respectively. Finally, nutritional parameters were related to operating conditions by the polynomial regression and desirability function methodology. Optimal operating conditions (1.4 m/s and 500 W) were found, which provides a product of excellent final quality.

Published: April 2022

The phase diagram of the Ni–Cr–Al–Y system can provide theoretical guidance for the composition design of NiCrAlY alloy coated on the surface of Ni-based superalloy, and as Ni–Cr–Y is a sub-ternary system of Ni–Al–Cr–Y, its phase relationship is the basis in establishing the thermodynamic database of Ni–Al–Cr–Y system. In the present work, the isothermal section of the Ni–Cr–Y ternary system at 900 °C is experimentally determined using the equilibrated alloys method combined with scanning electron microscopy and energy dispersive X-ray spectroscopy and X-ray diffractometry. Eight three-phase regions are confirmed and one three-phase region can be deduced in the isothermal section, and no new ternary compound is found.
Sociopragmatics of compliment-responding behavior in Taiwanese Mandarin
Authors: Tang Chihsia
Published: April 2022

This study examined whether and, if so, how Taiwanese Mandarin speakers’ compliment-responding behaviors are related to their gender and the gender and relative social power of their addressees. The data of the current study were collected from a discourse completion test. Forty-eight Taiwanese Mandarin native speakers participated in this study. The coding scheme encompassed seventeen microstrategies, which were further categorized into four macro-categories, including ACCEPTANCE, AMENDMENT, NONACCEPTANCE, and EVADING. Results showed that the controlled variables were all significant to the participants’ compliment response use. There are also some interactive effects between these variables on the complimentee’s compliment-responding behavior. Different microstrategies were employed to react to the given compliments according to the social expectations on the complimentees in different social positions and of different biological gender identities as well as the complimentees’ psychological perceptions of the given positive remarks. Moreover, the results also found that acceptance-oriented responses had a wider distribution in the present database. This might be attributed to that people in Taiwan nowadays place more emphasis on positive politeness and the value of prioritizing the self rather than the traditional Confucian value of humility.
Effects of Crack Width and Healing Time on Healing Performance of Microcapsule-Based Self-Healing Concrete
Authors: Lin Zhiyang , Kanwal Humaira , Hao Wenfeng
Published: April 2022

Self-healing concrete is one of the effective methods for solving concrete deterioration and improving durability. However, the effects of crack width and healing time on healing performance are still part of an open problem. In this paper, the effects of crack width and healing time on healing performance of microcapsule-based self-healing concrete are studied. First, the chloride ion permeability tests were conducted to evaluate the effects of crack width and healing time on chloride ion permeability of the self-healing concrete. Then, three-point bending tests were conducted to study the effects of crack width and healing time on flexural behavior of the self-healing concrete system. The results show that the chloride ion penetration healing rate decreases significantly with the increase of crack width. The increasing trend of the healing rate of the specimens healing for 7 days and 14 days is faster, while the increasing trend of the healing rate of the specimens healed for 56 days is slower. When the crack width is less than 0.05 mm, the self-healing can restore or even exceed the initial performance of concrete specimens. When the crack width exceeds 0.15 mm, the damage degree has exceeded the healing capacity of the healing system, and it is difficult to restore the initial performance of concrete. This work provides a valuable reference for the design and preparation of self-healing concrete structures.
Critical food guidance from the slow food movement: The relationship barometer
Authors: Fader Brooke , Mesmain Michèle , Desjardins Ellen
Published: April 2022

The Slow Food movement embeds food guidance that encourages interaction with local food production and appreciation of local cuisine. It advocates critical thinking and actions that support the preservation of traditional food practices, as well as environmental considerations around food harvesting and processing. We begin by contextually situating Slow Food as a movement and a change agent. We then introduce a critical guidance tool called the Slow Food Relationship Barometer, developed by Fader and Mesmain from their experience in southern Vancouver Island, British Columbia. This tool is meant for use by advocacy groups and policy makers rather than individuals. It is based on the view that identifying and assessing the multiple relationships intrinsic to a local food product—from origins to the table—can reveal pathways toward its improved sustainability. We illustrate how the Relationship Barometer can be applied to the case of wild and farmed salmon, which also underlies the Slow Fish movement.
Seizing this COVID moment: What can Food Justice learn from Disability Justice?
Authors: Stiegman Martha
Published: April 2022

It is now a shameful truism that COVID-19 functioned as a big reveal, exposing, and amplifying the structural inequalities Canadian society is built upon. We are now a year and a half into the global pandemic. I am writing from Toronto, where “hot spots” (neighbourhoods with high infection rates) is code for racial and economic inequality (Wallace 2021) and public health guidelines have rendered low income “essential workers” disposable, amidst ballooning food insecurity rates, especially in low-income racialized communities (Toronto Foundation 2020; CBC News 2020). We are all in the same storm but in very different boats, as the new saying goes. I want to suggest that this moment, as Canadians are poised to step out of lockdown and return to ‘normal’, is a particularly useful one for Food Studies to consider what we could learn from Disability Justice movements in order to address a glaring hole in our collective scholarship and analysis.

Authors: Moffat Tina , Oresnik Sarah , Angelo Amy , Chami Hanine , D'aoust Krista , Elshahat Sarah , Guo Yu Jia
Published: April 2022

In this article we present accounts of two youth food programs operating at a Community Food Centre.  One program, Kids Club, engages children, aged 6 to 12, in cooking and gardening activities; the other, Cookin' Up Justice, is directed to adolescents (13 to 18 years) and explores food justice concepts through experiential group cooking.  A variety of ethnographic methods including participant-observation, semi-structured interviews, focus group and photovoice discussions done with youth participants and parents are used to document how the food programs incorporate innovative aspects of Critical Food Literacy and Food Justice. We address the successes, challenges, and opportunities in delivering youth food programs that incorporate both the “practical” and “political” dimensions of Food Literacy and Critical Food Literacy with particular attention to food politics that arise when working with racialized, newcomer participants living in a lower socioeconomic neighbourhood.  We also discuss the challenges and opportunities in doing food programming with the adolescent demographic.  We recommend that community food programs incorporate an analysis of the cultural, racialized, class, and gendered aspects of their staff and participants into the Critical Food Literacy and Food Justice dimensions of their programs to promote anti-racist and inclusive program design and facilitation.
Facing Catastrophe? Food Politics and the Ecological Crisis By Carl Boggs
Authors: Shankland Amanda
Published: April 2022

In his most recent work, Facing Catastrophe, Boggs takes aim at the environmental movement and calls for radical reform. The author argues that political change matching the extent of the ecological problems we face is urgently needed, and that “there can be no routine, painless ‘greening’ of a neo-liberal world order rooted in the incessant accumulation of wealth, power, and geopolitical advantage, and protected by the largest military apparatus in history (Boggs, 2020, p. xvii).” The book makes suggestions for reform that include redirecting military funds toward the environment, reducing the number of people living in cities, and transitioning to plant-based diets across the world.
Critical food guidance
Authors: Desjardins Ellen , Sumner Jennifer
Published: April 2022

In this themed section, we argue that beyond health-related dietary goals for society, food guidance must also reflect the expanding public awareness and uncertainty about the complexities and vulnerabilities of the current food system. Increasingly influential issues include environmental change, agriculture-related pollution, food worker injustice, animal welfare, persistent household food insecurity, food waste, and fish stock depletion. No form of food guidance can address all these complex phenomena, but many people want to be informed and empowered to make change. Accordingly, academic and citizen groups have been devising an assortment of directives, recommendations, principles, and charters to promote alternative food environments and food behaviours that cumulatively support sustainable food systems. These on-going debates and efforts can collectively be termed critical food guidance.

Published: April 2022

Die Digitalisierung der Finanzbranche schreitet weiter voran. In den letzten Jahren haben sich insbesondere sog. Robo-Advisors am Markt etabliert, welche die üblicherweise höchst komplexen und individuellen Finanzdienstleistungen der Anlageberatung und der Vermögensverwaltung auf der Basis von Algorithmen ganz oder teilweise digital erbringen. Neben technischen Innovationen haben die letzten Jahre auch Entwicklungen rechtlicher Natur mit sich gebracht. Vor allem das Inkrafttreten des WpIG erfordert eine angepasste rechtliche Bewertung des Robo-Advice. Der folgende Beitrag gibt einen Überblick über aktuelle Rechtsfragen und ordnet das Robo-Advice in den geltenden Rechtsrahmen ein.
DAILY ACTIVITY OF THE HORSE FLIES (DIPTERA: TABANIDAE) IN THE CENTRAL BALKAN MOUNTAINS, BULGARIA
Authors: Ganeva D.
Published: April 2022

A study was conducted on the dynamics of tabanids daily activity in the Central Balkan Mountains in the 2011-2013 period. Tabanids have been found to fly 11 hours a day, with a peak in activity around 11:00. Their mass activation is in the temperature range 18-23°С and at 26°С maximum activity has been reported. In the present study a new, minimum temperature threshold for activation of T. quatuornоtatus Mg. in Bulgaria was registered (13°С).
APPAREND AND TRUE METABOLIZABLE ENERGY OF HIGH PROTEIN SUNFLOWER MEAL IN BALANCE EXPERIMENTS WITH ROOSTERS
Authors: Chobanova S. , Penkov D.
Published: April 2022

Aim: To establish the zero nitrogen corrected apparent (AMEn-o) and the true (TMEn-o) metabolizable energy of two batches high – protein (dehulled, with 45 and 50% crude protein in DM) sunflower meal.
Material and Methods: Standardized methods for balance experiments with poultry. The roosters were 1 year old – White Plymouth Rock – race. Six birds were tube fed and six feed deprived per each batch of fodder. Separately experiments with intact and caecoectomized roosters were conducted.
Results: The following levels (J/g DM) have been established: Batch 45%: (AMЕn-o): intact: 8430, caecoectomized: 8317, mean: 8373; (TMЕn-o): intact: 9221, caecoectomized: 9108, mean: 9164. For the batch 50% the results were: 9281, 10061, mean - 96711 and 9943, 10973, mean - 10458 J/g DM respectively.
Conclusion: The authors suggest that both feed batches can replace isoenergetic soybean meal in combined fodders for poultry.
INFLUENCE OF THE PUN1 GENE ON CAPSAICIN SYNTHESIS IN HYBRID LINES OF THE GENUS CAPSICUM
Authors: Srebcheva T. , Kostova M.
Published: April 2022

The fruits of the Capsicum genus plants are valued for their spicy taste, unique only to them, due to the capsaicin alkaloid and its analogs, named capsaicinoids. Capsaicinoids are absent in sweet peppers, which are sometimes preferred due to the lack of pungency. Their presence or absence is a genetically controlled process, and many of the genes that affect capsaicin synthesis are known. The Pun1 gene plays a lead, and mutations in this locus are the most common cause of loss of pungency in the three related species Capsicum annuum, Capsicum chinense, and Capsicum frutescens. In the present study, we analyzed the effect of the Pun1 gene on the synthesis of capsaicin in hybrid lines of the genus Capsicum. This analysis was performed by comparing the fruit spiciness profile (determined organoleptically) and the allelic state of the Pun1 gene (determined by PCR reaction, using allele-specific primers). The comparative analysis confirms our hypothesis that the pungent and lack of pungent in the selected hybrid lines is entirely controlled by the action of this Pun1 gene only.
MANAGEMENT OF TOOTH EXTRACTIONS IN PATIENTS RECEIVING THE NEW ORAL ANTICOAGULANTS
Authors: Vladimirova-Kitova L. , Dinkova A. , Daskalov C. , Kitov S.
Published: April 2022

Introduction: High bleeding risk procedures pose a serious challenge for dental practitioners treating patients taking some of the novel oral anticoagulants.
Aim: The aim of the present study was to assess clinically the bleeding risk in a typical tooth extraction in patients on monotherapy with one of the new oral anticoagulants rivaroxaban (Xarelto), apixaban (Eliquis), and dabigatran (Pradaxa).
Materials and methods: The study included 30 patients on these anticoagulants who underwent a typical tooth extraction. Local hemostasis was achieved using Surgicel, Haemocollagen or Gelaspon, and suturing the edges of the wound. Clinical evaluation of the bleeding was performed at 10 and 30 minutes, and 24 hours after the extraction. Anticoagulants were discontinued for the day of extraction.
Results: Post-extraction bleeding in the first 10 minutes was observed in 17 patients (56.66%). Bleeding within 30 minutes was observed in 11 patients (36.66%). Two (6.66%) patients reported having only mild oozing within 24 hours. No additional haemostasis was required for any of the patients.
Bleeding in a typical tooth extraction is of capillary origin. Bleeding sites are easily accessible and local hemostatic agents are effective enough to control the bleeding. Discontinuation of the anticoagulant on the day of extraction is sufficient to prevent any adverse events. No abnormal post-extraction bleeding was observed in our study.
Conclusions: If tooth extraction is required in patients taking the new oral anticoagulants rivaroxaban (Xarelto), apixaban (Eliquis) or dabigatran (Pradaxa), the patient can cease the reception of the drug only for the day of the procedure.
