Authors: Агапов П.В. , Шевелева К.В.
Published: July 2023

В статье исследуются вопросы искажения исторических фактов о деятельности СССР в период Второй мировой и Великой Отечественной войн, анализируются последствия фальсификации истории для Российской Федерации, рассматриваются уголовно-правовые средства противодействия подобным явлениям. Именно уголовно-правовые меры являются одним из основных средств противодействия посягательствам, связанным с попытками реабилитации нацизма и искажения исторической правды. Их совершенствование является важным условием и залогом успешного, долговременного и четкого применения всего комплекса мер, используемого в данной области. В свою очередь, выработка эффективных правовых механизмов противодействия попыткам искажения исторической правды требует совместных системных действий и постоянного внимания со стороны органов публичной власти всех уровней и институтов гражданского общества. Авторами изучены проблемы действующей уголовной ответственности за фальсификацию исторических сведений (ст. 354.1 УК РФ), сформулированы предложения по совершенствованию законодательства. В результате исследования представлены авторское определение «фальсификации истории» и макет новой уголовно-правовой нормы, устанавливающей ответственность за фальсификацию исторических сведений о деятельности СССР в годы Второй мировой и Великой Отечественной войн.

The article examines the issues of distortion of historical facts about the activities of the USSR during the Second World War and the Great Patriotic War, analyzes the consequences of falsification of history for the Russian Federation, considers criminal law means of counteracting such phenomena. It is criminal law measures that are one of the main means of countering encroachments related to attempts to rehabilitate Nazism and distort historical truth. Their improvement is an important condition and the key to the successful, long-term and clear application of the entire set of measures used in this area. The author studied the problems of the current criminal liability for the falsification of historical information (Article 354.1 of the Criminal Code of the Russian Federation), formulated proposals for improving the legislation. As a result of the study, the author's definition of «falsification of history» and a model of a new criminal law norm establishing responsibility for falsifying historical information about the activities of the USSR during the Second World War and the Great Patriotic War are presented.
LEGAL STATUS OF PRIVATE MILITARY COMPANIES IN THE RUSSIAN FEDERATION
Authors: Галактионов С.А. , Кулаков А.В.
Published: July 2023

Статья посвящена актуальным и дискуссионным в настоящее время вопросам, связанным с деятельностью частных военных компаний. Отмечается, что в последние три-четыре десятилетие значительно выросло количество частных военных компаний, а их совокупная численность стала превышать более пяти миллионов человек. Свою деятельность частные военные компании осуществляют более чем в 110 странах мира. Не является исключением и Россия, в которой функционирует более десятка ЧВК, наиболее известными из которых являются «Вагнер», «Редут», «РСБ Групп» и др. Несмотря на столь широкий географический охват и спектр деятельности, пересекающийся с государственными интересами, ни в России, ни в других странах нет единого мнения относительно статуса сотрудников ЧВК и их сотрудников. Правительства различных стран предлагают рассматривать сотрудников ЧВК в качестве комбатантов, гражданских подрядчиков, наемников-преступников. Подвергая анализу российские законопроекты и международно-правовые акты, затрагивающие рассматриваемую проблему, авторы делают вывод о необходимости принятия специального закона, регулирующего деятельность частных военных компаний, зарегистрированных на территории РФ.

The article is devoted to topical and currently debatable issues related to the activities of private military companies. It is noted that in the last three or four decades, the number of private military companies has grown significantly, and their total number has exceeded more than five million people. Private military companies operate in more than 110 countries around the world. Russia is no exception, where there are more than a dozen PMCs, the most famous of which are Wagner, Redut, RSB Group, etc. Despite such a wide geographical coverage and a range of activities that intersect with state interests, neither in Russia nor in other countries there is a consensus on the status of PMCs employees and their employees. The governments of various countries propose to consider PMCs employees as: combatants; civilian contractors; criminal mercenaries. Analyzing Russian draft laws and international legal acts affecting the problem under consideration, the authors conclude that it is necessary to adopt a special law regulating the activities of private military companies registered in the territory of the Russian Federation.

Authors: Илюхин С.Е. , Юсупов Д.Х.
Published: July 2023

Обеспечение пожарной безопасности в исправительных колониях и следственных изоляторах (далее – СИЗО) играет важную роль в процессе исполнения и отбывания наказаний, оказывая благоприятное влияние на оперативную обстановку в учреждениях уголовно-исполнительной системы Российской Федерации (далее – УИС). Пожары вносят дестабилизацию в установленный внутренний распорядок дня, провоцируют неповиновения, недовольства осужденных, создают обстановку, в которой складываются побегоопасные ситуации, причиняют имущественный, материальный вред, а также вред жизни и здоровью лиц, находящихся на территории объектов УИС. Именно поэтому необходимо детально и всесторонне изучать вопросы обеспечения мер противопожарной безопасности в исправительных колониях и СИЗО УИС. Отметим, что раз в полгода ФСИН России проводит мониторинг пожаров и состояния пожарной безопасности в учреждениях УИС, что позволяет отслеживать динамику по устранению недостатков, касающихся укомплектования исправительных колоний и СИЗО пожарной техникой, укомплектованности личного состава, а также анализировать количество пожаров, их причины и условия, вырабатывать новые и совершенствовать старые мероприятия по обеспечению противопожарной безопасности на объектах УИС в современных реалиях.

Ensuring fire safety in correctional colonies and pre–trial detention centers (hereinafter referred to as SIZO), of course, plays a huge role in the process of execution and serving sentences, having a favorable impact on the operational situation in institutions of the penal system (hereinafter referred to as UIS). Fires, in turn, destabilize the established internal daily routine, provoke disobedience, discontent of convicts, cause life-threatening situations, cause property, material damage, as well as harm to the life and health of all persons located on the territory of the facilities of the penal system. That is why it is necessary to study in detail and comprehensively the issues of ensuring fire safety measures in correctional colonies and pre-trial detention centers. It should be noted that every six months the Federal Penitentiary Service of Russia monitors fires and the state of fire safety in penal institutions, which allows you to track the dynamics of eliminating deficiencies in staffing correctional colonies and pre-trial detention centers with fire equipment, staffing, analyze the number of fires, their causes and conditions. And also to develop new and improve old measures to ensure fire safety at UIS facilities in modern realities.

In den letzten Jahrzehnten hat sich die Technik dramatisch entwickelt. Wir verfügen nunmehr über Produkte, von denen niemand zu träumen wagte. Die digitale Revolution hat unser Leben völlig umgekrempelt. Das Mobiltelefon ist unser ständiger Begleiter. Und diese Minicomputer sind leistungsstärker als die Bordcomputer der ersten Mondlandefähre. Aber wenn die Computer in Autos, Schiffen, Flugzeugen ein Eigenleben entwickeln oder nicht verstanden werden, dann wird es gefährlich, sogar lebensgefährlich. Beispiele gibt es viele, zum Beispiel aus der Luftfahrt.

Bemerkenswerte Zusammenhänge zwischen der Mathematikleistung und dem räumlichen Denkvermögen von Primarstufen- und Sekundarstufenschüler*innen
Authors: Köck Julia , Maresch Günter
Published: July 2023

In einigen internationalen Studien der letzten Jahre wurde ein möglicher Zusammenhang zwischen der Mathematikleistung und dem räumlichen Denkvermögen untersucht. Zum einen wurde dabei festgestellt, dass Personen mit Stärken in den MINT/STEM-Feldern bei Raumvorstellungstests besser abschneiden. Zum anderen konnte beobachtet werden, dass durch Training des räumlichen Denkvermögens eine Verbesserung der Mathematikleistung bewirkt werden kann. Die Verhaltens- und Gehirnforschung erklärt diese Transferleistung dadurch, dass beim Verarbeiten von räumlichen und numerischen Informationen ähnliche neuronale Netzwerke zum Einsatz kommen. In der in diesem Beitrag vorgestellten Studie wurde das räumliche Denkvermögen von Schüler*innen (N = 237) im Alter von 8 – 13 Jahren anhand einer Testung bestimmt und zudem wurde die Note im Unterrichtsfach Mathematik erfasst. Die Analyse zeigt, dass jene Schüler*innen mit einer besseren Mathematiknote auch bei der Testung zum räumlichen Denkvermögen ein besseres Ergebnis erzielen und dass diese Effekte über alle Altersgruppen hinweg zumeist groß sind.

Spezifika mathematischen Denkens lassen sich durch Aufgaben verdeutlichen.
Die Entwicklung stochastischen Denkens
Authors: Borovcnik Manfred , Vancsó Ödön
Published: July 2023

Stochastisches Denken beinhaltet den Umgang mit Unsicherheit und die Einbeziehung von Wahrscheinlichkeiten in die Entscheidungsfindung, wobei die Variabilität und die unvollkommenen Informationen in der realen Welt berücksichtigt werden. Es umfasst Schlüsselelemente wie Wahrscheinlichkeitsbewertung, Erkennen von Unsicherheit, Datenanalyse, Aktualisierung von Überzeugungen, Risikobewertung, Entscheidungsfindung unter Unsicherheit, Szenario-Analyse und Bayessches Denken. Im ersten Abschnitt befassen wir uns mit probabilistischem und statistischem Denken und dem Unterschied zwischen diesen beiden Denkweisen. Probabilistisches Denken ermöglicht es dem Einzelnen, mit Ungewissheiten umzugehen, fundierte Entscheidungen zu treffen und die Variabilität der Welt zu verstehen. Obwohl es dem statistischen Denken ähnlich ist, unterscheidet es sich in Bezug auf Schwerpunkt, Umfang, Kontext, Methodik und Anwendung. Um probabilistisches Denken zu fördern, werden Schlüsselkonzepte hervorgehoben, darunter Wahrscheinlichkeit, Quantifizierung von Wahrscheinlichkeiten, Ungewissheit, bedingte Wahrscheinlichkeit, Unbeständigkeit, Stichproben, Variation und Verteilung sowie Erwartungswert. Das Verständnis dieser Konzepte verbessert das probabilistische Denken und die Entscheidungsfähigkeit. Die Betonung dieser Konzepte im Unterricht durch Beispiele und Visualisierungen vertieft das Verständnis und die Anwendung probabilistischen Denkens. Im zweiten Abschnitt wird die Rolle der Intuition, der grundlegenden Ideen und des stochastischen Denkens im Mathematikunterricht mit Schwerpunkt auf Wahrscheinlichkeit erörtert. Die Aneignung von Konzepten beinhaltet ein Zusammenspiel zwischen primären Intuitionen und theoretischem Input. Theoretische Konzepte zielen darauf ab, sekundäre Intuitionen aufzubauen, aber isolierte Konzepte haben wenig nachhaltige Wirkung. Der Ansatz des operativen Konzepterwerbs ist für die Wahrscheinlichkeit aufgrund der Unsicherheit begrenzt. Über grundlegende Ideen der Wahrscheinlichkeit, wie z. B. die Überprüfung von Informationen und statistische Schlussfolgerungen gibt es durchaus unterschiedliche Auffassungen. Es gibt verschiedene Auslegungen der Wahrscheinlichkeit: frequentistisch, subjektiv und a priori. Stochastisches Denken und Intuition prägen theoretische Konzepte, und die Wahrnehmung von Zufallsvariationen ist in der Statistik von entscheidender Bedeutung. Die deskriptive Statistik, die Wahrscheinlichkeitstheorie und die statistische Schlussfolgerung bieten unterschiedliche Sichtweisen auf dieselben Informationen. Bei der statistischen Schlussfolgerung geht es um die Repräsentativität von Stichproben und um Zufallsstichproben. Der Text hebt die Bedeutung von Intuition, grundlegenden Ideen und stochastischem Denken im Mathematikunterricht hervor und betont die Erforschung von Interpretationen und Perspektiven für ein tieferes Verständnis der Wahrscheinlichkeit.

In diesem Beitrag werden ausgehend von einem gestuften Ansatz zur Operationalisierung von mathematischen Denkaktivitäten (Lernhandlungen) im Rahmen der Leitidee „Raum und Form“ curriculare Aspekte im Kontext der aktuellen deutschen Bildungsstandards bis zum mittleren Schulabschluss betrachtet und beispielhaft diskutiert. Im Zentrum stehen zwei Ansätze zur Weiterentwicklung der Kerncurricula: Ein Weg zur Verknüpfung von allgemeinen (prozessbezogenen) Kompetenzen und Lerninhalten verbunden mit der Aufnahme von grundlegendem Metawissen über die relevanten Lernhandlungen, die damit dann selbst zum Lerngegenstand werden, sowie eine strukturelle Verankerung kumulativen Kompetenzaufbaus zu den relevanten Lernhandlungen über verschiedene Stützpfeiler im Spiralcurriculum.
Overcoming Circular Economy Challenges in Port Areas: An Institutional Perspective
Authors: Kadio Aya Kan Christiane , Fernandes Valérie
Published: July 2023

The implementation of circular economy practices is a current and important topic. Despite extensive research on CE barriers in various industries and countries, there is limited discussion on circular economy challenges in port areas. This paper aims at empirically studying circular economy implementation, its associated obstacles, and the levers to overcome them by mobilizing institutional theory. To this end, we studied six cases of companies, located in a port area in France, that have implemented circular economy in their practices. We deployed a qualitative case study methodology. As results, we have identified 41 challenges divided into 5 groups: (1) economic-financial-market, (2) organizational-managerial-cultural, (3) technical-technological, (4) regulatory-governmental, (5) supply chain. The results were then interpreted through the lens of institutional theory. We found that institutional mechanisms - coercive, normative, mimetic, and informal instruments - can be mobilized so as to meet each of the challenges.
Композиционное вяжущее с энергосберегающим сырьем для высокопрочного бетона
Authors: Лесовик Валерий , Елистраткин Михаил , Сальникова Алена , Фомина Екатерина
Published: July 2023

В данной работе с позиции научного направления геоники «геомиметики» рассматривается вопрос повышения эффективности высокопрочного самоуплотняющегося бетона за счет использования отходов строительных материалов в виде боя керамического кирпича, лома тяжелого бетона и газосиликата. Установлено, что применение отсева дробления бетонного лома в составе сырьевой смеси способствует повышению устойчивости бетона к расслоению и водоотделению при оптимальных реологических свойствах с улучшением физико-механических свойств композиционного вяжущего и мелкозернистого бетона на его основе. Возможна экономия до 30 % портландцемента в составе композиционного вяжущего при замене на техногенное сырье. Максимальный эффект самоуплотнения сырьевой смеси проявляется в достаточной степени при использовании боя керамического кирпича. Однако, в совокупности характеристик максимальной прочности и размолоспособности предпочтительным является использование тонкомолотого лома бетона. Исследования направлены на максимальное раскрытие ресурсного потенциала техногенного сырья в виде отсевов дробления фрагментов зданий и сооружений, образующихся в следствии реновации строительного комплекса страны, а также на освобожденных территориях ЛНР и ДНР.

Authors: Федосов Сергей , Федосеев Вадим Николаевич , Зайцева Ирина Александровна , Воронов Владимир Андреевич
Published: July 2023

Рост популярности применения теплогенераторов на основе возобновляемых источников — воздушных тепловых насосов сопровождается увеличением актуальности вопроса их модернизации с целью увеличения эффективности. При этом немаловажную роль играет рабочая среда внутреннего контура теплового насоса — хладагент(фреон). На выбор фреона накладывает ограничения Монреальский протокол, согласно которому использование веществ, разрушающих озоновый слой, запрещено. При выборе хладагента необходимо учитывать все качества и факторы, характеризующие возможности в условиях их работы. На основе информации из отечественных и международных нормативных документов можно сформировать группы требований, предъявляемых при выборе хладагента для воздушного теплового насоса, оптимальные по различным предъявляемым критериям. В частности, в отношении безвредности для человека можно также выделить группу требований для фреонов: практический предел концентрации хладагента и предельно допустимую концентрацию. На сегодняшний день крайне важным является оценка и учет показателей экологической безопасности хладагентов. В данной статье приводится оценка показателей экологичной безопасности выбранной группы фреонов, отобранных по критерию частоты использования. Оценивая показатели экологической безопасности анализируемых хладагентов, отобранные, приоритетные показатели были составлены в один обобщающий (интегральный) показатель, по значению которого появляется возможность судить об экологической безопасности хладагентов. Для этого рассматриваем наибольшие и наилучшие значения. Результаты исследования представлены в виде инфографической модели.

Published: July 2023

As tecnologias verdes assumiram uma posição importante para o desenvolvimento da sustentabilidade global, e a transferência de tecnologias pode ser um mecanismo pelo qual as indústrias podem conquistar e manter sua competitividade no mercado e garantir a sustentabilidade, promovendo uma atitude de mudança e de acompanhamento das necessidades humanas, econômicas, sociais e ambientes da era atual. O objetivo geral da tese consistiu em desenvolver um modelo conceitual de processo de transferência de tecnologia verde para os Institutos de Ciência e Tecnologia brasileiros, tendo o NIT como o agente facilitador para a cooperação. Com a revisão sistemática da literatura realizada sobre os processos e modelos de transferência de tecnologia, foi possível verificar que ainda não existem modelos aplicados para tecnologias verdes. Através da ferramenta proposta para avaliar a estrutura de transferência de tecnologia, foi possível verificar quais dimensões integram o modelo e sua integração com os grupos de pesquisa e NITs. O modelo proposto elaborado consistiu em etapas três macro fases, pré-transferência, desenvolvimento e pós-transferência, através deste modelo é possível apontar, antecipadamente, as principais barreiras que impedem esse processo, além de fomentar desenvolvimentos científicos e tecnológicos futuros capazes de influenciar de forma significativa nas indústrias, uma vez que anteciparia futuros problemas relativos à propriedade intelectual que possam inviabilizar a cooperação entre universidade-indústria no Brasil.
Phosphodiesterase type 5 Inhibitors (PDE-5I) as a potential therapeutic drug in stroke: A systematic narrative review

Objectives. Stroke is an acute cerebrovascular disease with high morbidity and mortality rate. Many stroke management strategies can improve prognosis and quality of life, but only to a certain extent. Phosphodiesterase inhibitor-5 (PDE-5i) has shown benefits in numerous preclinical studies, but human studies have been inconclusive. Material and Methods. For this narrative review, we conducted a systematic search following the PRISMA statement guideline from inception until November 2022. The search was conducted in PubMed, ScienceDirect, EBSCOhost, and ProQuest. We included all human and animal studies on this topic, including preclinical studies, randomized clinical trials, and case studies. All the excluded studies are reviews or non-English studies. Review. Many PDE-5i have shown benefits in anatomical and functional outcomes in preclinical acute experimental stroke models. PF-03049423 was safe and well tolerated in humans but had no significant impact on neurological or functional outcomes. Sildenafil on acute/subacute was deemed safe to use and demonstrated improvement over baseline, but power remains unknown due to the lack of a control group. Tadalafil use resulted in a reduction in regional cerebral blood flow in subjects with a history of stroke. Conclusions. Despite promising results in preclinical studies, current evidence shows that PDE-5i does not affect clinical or functional recovery in people with acute stroke. The disparity in the intricacy of stroke pathophysiology between human and animal models was crucial. Further research in a larger population with more consistent stroke onset, medicines, and doses is required for a more conclusive result.

Meterwavelength Single Pulse Polarimetric Emission Survey. VI. Toward Understanding the Phenomenon of Pulsar Polarization in Partially Screened Vacuum Gap Model
Authors: Mitra Dipanjan , Melikidze George I. , Basu Rahul
Published: July 2023

We have observed 123 pulsars with periods longer than 0.1 s in the Meterwavelength Single Pulse Polarimetric Emission Survey. In this work, a detailed study of the polarization behavior of these pulsars has been carried out. We were able to fit the rotating vector model to the polarization position angle sweeps in 68 pulsars, and in 34 pulsars the emission heights could be measured. In all cases the radio emission was constrained to arise below 10% of the light cylinder radius. In pulsars with low spin-down energy loss,

erg s−1, we found the mean fractional linear polarization of the individual time samples in single pulses to be around 0.57 (57%), which is significantly larger than the fractional linear polarization of 0.29 (29%) obtained from the average profiles. On the other hand, the mean fractional circular polarization of the individual time samples in single pulses is around 0.08 (8%), similar to the measurements from the average profiles. To explain the observed polarization features, we invoke the partially screened vacuum gap model of pulsars, where dense spark-associated plasma clouds exist with high pair plasma multiplicity, with significant decrease of density in the regions between the clouds that are dominated by iron ions. The coherent radio emission is excited by curvature radiation from charge bunches in these dense plasma clouds and escape as linearly polarized waves near cloud boundaries. We suggest that the circular polarization arises due to propagation of waves in the low-pair-multiplicity, ion-dominated inter-cloud regions.
The phylogenetic position of the Isopoda in the Peracarida (Crustacea: Malacostraca)
Authors: Wilson George
Published: July 2023

The sister group to the isopod crustaceans remains a controversial proposition. Previous studies have used idealised composite taxa or few exemplars, resulting in confl icting assertions about the placement of the Isopoda among the Malacostraca. A recent morphological study argued for an Amphipoda-Isopoda clade, whereas a molecular study using SSU rDNA (18S) data found other relationships. Within isopods, the morphologically-specialised Phreatoicidea are generally regarded as the earliest-derived taxon, based on their fossil record and several published cladograms. These hypotheses were tested using 18S sequences and 202 morphological characters from 75 exemplars (52 isopods and 23 other malacostracans). The partitions were analysed separately and combined, and the sequence data were analysed using dynamic homology. To find the best sequence substitution, insertion-deletion and gap insertion costs, scores based on finding accepted monophyletic taxa were used to select the optimal parameters. Separately and combined, both partitions rejected the Amphipoda-Isopoda clade hypothesis. The 18S analysis placed the phreatoicideans high in the tree, rather in a basal position. The morphological analysis found a basally branching Phreatoicidea-Asellota group. The combined analysis found an Apseudomorpha (Tanaidacea) + Isopoda clade, with Phreatoicidea still well separated from the isopod ancestral root. The parasitic subgroups of the Cymothoida (families Cymothoidae and Gnathiidae, and superfamily Bopyroidea) comprised the basal branch of the isopods, which is a novel hypothesis that argues against the monophyly of the suborder Cymothoida. The 18S data alone are inadequate at this phylogenetic level and the combined data provided novel hypotheses that require additional evidence from detailed morphological studies and DNA markers for confi rmation.
An alternative host searching strategy found in the subfamily Hybrizontinae (Hymenoptera, Ichneumonidae)
Authors: Hisasue Yu , Konishi Kazuhiko , Takashino Kenji
Published: July 2023

The present study reports the oviposition behavior of the ant parasitoid wasp, Ghilaromma orientalis, on an undescribed ant species from Lasius fuliginosus species group in Japan, illustrated by clear photographs. Previously, the oviposition behavior in the subfamily Hybrizontinae had been limited to species hovering on an ant trail and attacking larvae carried by worker ants. In contrast, in G. orientalis, whose oviposition behavior had not been reported to date, the wasp hung on the grass growing along the ants’ trail by its hind legs with its head down, and when workers with larvae pass by, directed its abdomen toward the larvae with its hind legs remaining on the grass. Our findings suggest that the subfamily Hybrizontinae employs two host-searching strategies—an active strategy previously known and the ambush-type host-searching strategy employed by G. orientalis. The ambush-type strategy affords G. orientalis the advantage of laying eggs in a narrow environment where wasps cannot fly without being noticed by ants. Moreover, by avoiding detection through ambush tactics, wasps are increasing their chance for attack, as ants continue to transport their larvae. However, the search range of wasps is reduced, which may limit the opportunities for parasitization. Additionally, while Lasius nipponensis has been observed as the sole known host of G. orientalis, the oviposition behavior has now been observed in an undescribed species of L. fuliginosus group, suggesting that G. orientalis may have a subgenus-specific host range.
Reclaiming the Narrative and Re-professionalising the Teacher: Responding to the Homogenous and Prescriptive Policy in ITE in England

The aim of the Department for Education's recent market review of England's initial teacher training (ITT) was ostensibly to enable the provision of consistently highquality training in line with the ITT core content framework (CCF). Its intention may possibly have been welcomed had
it built on the judgments from Ofsted at the time, which concluded that every single teacher education partnership was already 'good' or better. However, this was not meant to be. The outcomes from the review led to a chorus of concerns voiced across the sector. A move to a single, potentially
homogenous national approach to the ITT curriculum, its delivery and its assessment was considered detrimental and central dangers were cited, such as the loss of autonomy and the investment partner schools have in ITT. Nevertheless, these concerns fell on deaf ears, with all ITT providers
being required to undergo formal reaccreditation despite their long track records of teacher training success. In this paper, we consider the prescriptive, homogenous nature of the ITT CCF to which providers must demonstrate fidelity in order to secure accreditation. We offer the University
of Manchester's Secondary Postgraduate Certificate of Education with Qualified Teacher Status programme (PGCE with QTS) as a case study. The paper illustrates the capacity of an academic and professional teacher training programme to extend beyond providing the prescribed minimum entitlement
and to develop trainee teachers as research informed, critically reflective practitioners.
'This is My City' - Reading Photo-Essays by my Berlin Pupils
Authors: Kazamias David
Published: July 2023

This paper offers readings of three examples from a photo-essay project undertaken in 2022 by a group of Year 7 pupils in Berlin. Many of the photo-essays centred on locations like schools, parks and shops, but also included places of worship, the graves of ancestors and evidence of
family ties in other cities. Mirroring the practices of the longstanding FORUM editor Michael Armstrong, I explore and reflect on how my pupils interact with the city and how the city interacts with the educational identities of my pupils.
Delivering a Science of Efficient Effectiveness for Stakeholders Investing in Children – or, the End of the Teacher?
Authors: Gardner-McTaggart Alex
Published: July 2023

This article considers the changed fortunes of teachers in 2023. It asks, 'how did we arrive at a culture of efficiency, effectiveness and delivery accountability – a culture which scares away our teachers?'. The thinking and language of Heidegger shows the power of language in
asserting dominance and changing cultures. The architect of Thatcherism and Blairism – the economist Friedrich Hayek – is introduced to clarify how we got here and why, finding the shared language of education destructed (as Heidegger might say) and colonised in favour of power
and the advantaged, while remaining deliberately ignorant of the powerless. This article questions the way we speak about education. Words are powerful; they recruit us to causes. Teachers and their communities can avoid the words of marketisation, avoid being recruited and turn the tide with
the language of educational professionalism.

Authors: Infantino Julieta
Published: July 2023

Um Brasil de Circos: a produção da linguagem circense do século XIX aos anos de 1930 (A Brazil of Circuses: the Production of Circus Language from the 1800s to the 1930s) is an impressive work. Its 520 pages are filled with rigorously presented data from 42 circus companies that performed in Rio de Janeiro during the nineteenth and early twentieth centuries. Its review highlights the main point of the book to emphasize its contribution to the history of the circus arts in particular, but also to the performing arts as well as social history in general.
Fair Terms of Social Cooperation among Equals
Authors: Otsuka Michael
Published: July 2023

Rawlsian justice as fairness is neither fundamentally luck egalitarian nor relationally egalitarian. Rather, the most fundamental idea is that of society as a fair system of cooperation. Collective pensions provide a case study which illustrates the fruitfulness of conceiving justice in these latter terms. Those who have recently reached the age of majority do not now know how long they will live in retirement or how well any investments they try to save up for their retirement would fare. From the perspective of the beginning of their working lives, it is therefore rational for each to enter into an agreement with others, who also do not yet know their fates, that, if one turns out to be among the unfortunate whose private pension pots would not have yielded enough for one’s retirement, one will receive much more in retirement, whereas those whose pension pots would have overflowed their retirements will receive somewhat less. These terms are to each person’s expected advantage, which is made possible by a fair sharing of the fruits of social cooperation which arise through the efficiencies reaped by the pooling of the risk of outliving what one could save for one’s retirement on one’s own. It is rational for each to agree to share one another’s fates by pooling risks across both space and time, on fair terms of social cooperation for mutual advantage. Even when collective pensions arise from, and are proportional to, a baseline of unequal income, they can be defended on grounds of reciprocity involving regard for one another as equals.

A theoretical investigation and evolution of the current rate produced in the Fe/molecule system results from charge transport interaction processes. The current flow charge rate properties of Fe metal contact with ZnPc organic sensitizers are investigated and studied based on analytical calculation and a simple quantum scenario model coupled with a semi-empirical continuum energy state. The current flow charge rate is done due to the transition energy, potential interface, driving energy, and coupling coefficient for considering Fe/ ZnPc system. The evolution of current flow charge rate for Fe/ ZnPc system with variety coupling coefficient. Fe/Zn-tri-PcNc-8 sensitized system is studied at room temperature. The flow charge rate of Fe/ ZnPc system results is found to be increasing with decreasing the transition energy and increasing the coupling coefficient. Potential at the interface is estimated according to energy absorption and transition energy. Our data shows that, at high polarity, the current flow charge rate is a smooth shift with propanol solvent compared with methanol, whereas at a higher transition energy for a system with methanol solvent. It is found that the Fe/ ZnPc system with propanol solvent has good mobility of electrons compared with methanol solvent.

Abandoned tin mines produce acid mine drainage in their water basin. If not treated well, it will damage environmental ecosystem by entering rivers or other water bodies. This acid mine drainage is attempted to be remediated by adsorption technique. The adsorbent used in this study is Lightweight Expanded Clay Aggregate (LECA) because its base material is natural clay. LECA is commonly used for hydroponics and constructions. LECA is made from natural clay that being heated at temperature over 1100°C. This study aims to determine how significant LECA in adsorbing metals in acid tin mine drainage. This research used two materials namely LECA and tin acid mine drainage. Both materials were contacted for two days in shaker bath. The results of this study were the adsorbing Fe(II) and Cu(II) on LECA could be approached by the Langmuir-Freundlich (LF) combined model where the Cµ,max are 0.406 and 0.020 mg/g of adsorbent, respectively. Unlike the other two metals, Sn(II) was more likely to experience precipitation instead of adsorption because of increasing of pH value. The conclusion, heavy metals in tin acid mine drainage could be remediated well by using LECA.

The coffee waste ground was applied as an adsorbent for methylene blue. The investigated adsorption parameters were adsorbent dose, contact time and percentage adsorption. The coffee waste ground was thoroughly simple and showed better adsorption than pure coffee waste. The high adsorption percentage of 96.98%, 97.99% and 98.14% was obtained when using the dose of adsorbent of 0.1, 0.2, and 0.25 g, respectively. The adsorption reached the equilibrium at 10 min of contact time. The adsorption capacity was 9.82 mg/g for 0.25 g of coffee waste ground. The maximum capacity of adsorption based on the Langmuir model was found to be 208.33 and 416.67 mg/g for pure coffee waste and coffee waste ground, respectively. The characterization of the adsorbent has been done using Scanning Electron Microscope (SEM) and Fourier Transform Infrared Spectrometer (FTIR). In conclusion, the coffee waste ground has potential as adsorbent to remove methylene blue in the wastewater. For the future, coffee waste ground can be a potential adsorbent to remove another waste in the water.
