Is the Blood Donation Deferral Policy a Reflection of Anti-LGBTQ Institutional Bias? Community Perceptions Amid the COVID-19 Pandemic
Authors: Gobrial Sarah , Lui P. Priscilla
Published: December 2021

As part of its responsibilities to protect the safety of the American public, the United States Food and Drug Administration (FDA) regulates activities associated with blood donation. One FDA policy concerns the deferral period of blood donation by men who have sex with men (MSM), and their sexual partners. The policy risks reinforcing stigma against people in the lesbian, gay, bisexual, transgender, queer/questioning (LGBTQ) community. The 2019 novel coronavirus pandemic created an urgent need for blood products; hence, the FDA shortened the deferral period for MSM and their sexual partners. Yet, the public’s support of the deferral policy remained unclear. U.S. community adults (N = 829, Mage = 46.83, 50.3% women, 9.5% lesbian, gay, bisexual (LGB) individuals) rated their approval of the FDA’s deferral policy and attitudes toward blood donations from people across various sexual orientations and gender identities. Approximately 78% of participants reported positive attitudes toward receiving blood from heterosexual donors, whereas 54% reported positive attitudes toward receiving blood from LGBTQ donors. Participants were inclined to believe that the 2020 policy revision was motivated by an increased demand for blood donations amid the coronavirus pandemic rather than an intent to reduce discrimination. Relative to LGB participants, heterosexual participants were less willing to receive blood from LGBTQ donors, more likely to endorse the FDA’s deferral policy, and less likely to consider this policy to be discriminatory. Grounded in a minority stress framework, understanding public opinion can contextualize the possible negative impact on LGBTQ health and inform future FDA policies.

The aim of this study was to stress the importance of investigating the properties of preservation enclosure materials in order to identify the ones that are able to protect their contents more efficiently. Since not all information on materials is covered by international standards and technical specifications, nine paper-based materials used for making preservation enclosures (file folders, passepartouts, boxes etc.) were investigated. A selective analysis of the materials' properties was carried out to determine smoothness, water absorptiveness, water wettability, water vapor permeability, tensile strength, folding endurance, bursting strength, puncture strength, as well as loss of bursting strength caused by dry heat and 100% RH. Results obtained from measuring smoothness, water absorptiveness, water wettability and water vapor transmission rate indicate that a material outside of ISO 16245:2009 grammage requirements for making file covers can exhibit more desirable properties than the one that meets multiple standards for storage and preservation. Additionally, results showed that bursting strength of enclosure materials was significantly affected by both extreme microclimate conditions. However, 100% RH had affected bursting strength of the investigated materials more than dry heat. The presented procedure proved to be a useful indicator of materials’ properties within the context of heritage collections preservation and storage
TAMBOV GOVERNING ELITE IN THE CONDITIONS OF POST-REFORM TRANSFORMATION
Authors: Erin P. V. , Nikolashin V. P.
Published: December 2021

The article examines the period (1861-1898) after the abolition of serfdom in the region of Central Russia. This period is characterized by a difficult situation for the further development of the country in the new realities. Despite the modernization message from the upper echelons of power, in the depths of the regional elite, serf attitudes and customs were preserved, which were supported by peasant’s patriarchal psychology. In this article the information on the adjustment of the nobility and landowners to the post-reform realities, on actions to realize their interests is supplemented. In carrying out the research, general scientific and special historical methods were used. The work is based on the archival sources of the State Archive of the Tambov Region. According to the results of the study, it can be noted that the local administrative elites were inclined to expand the boundaries of their own power. The modernization impulses directed from the capital, although caught by the Tambov leadership and the nobility, were implemented in a refined manner, drawing from the local interests. With the economic crisis, the "crisis of the management elite" also grew. Local authorities were increasingly distanced from the process of agricultural modernization in the Tambov province, not realizing that the agrotechnical backwardness of the region, which was aggravating over the years, was actually turning into a hotbed of great tension and threatened with serious conflict situations.

Authors: Abdulkareem Faaeza Ahmed , Hussain Tariq Abed , Najaf Ahmed A. Najaf
Published: December 2021

The undertaken study includes investigating the performance and effluent characteristics of the treatment plant of Al-Doura refinery. Influent concentrations for some important contaminants, which are TDS, oil and grease, TSS, COD, BOD, and turbidity were 2595 mg/L, 13934 mg/L, 466.45 mg/L, 2538.9 mg/L, 1739.2 mg/L, and 89.18 NTU, respectively, while the effluent concentrations were 1337.8 mg/L, 0.53mg/L, 21.7mg/L, 25.45 mg/L, 17.81 mg/L, and 7.08 NTU, respectively, giving removal efficiencies of 44.47%, 99.99%, 94.4%, 98.96%, 98.96% and 92.05%, respectively. All these results indicate that Al-Doura wastewater treatment plant was efficient in removing contaminants according to Iraqi and EPA specifications. Hence, the second part of this study concentrated on finding a simple and efficient treatment method to treat the effluent so that it can be reused in the boiler system. A pilot plant was designed and dedicated for this purpose, including three units of granular activated carbon filter, ultra filtration filter, and reverse osmosis filter. Average removal efficiencies of oil and grease, turbidity, COD, and BOD were 85.25%, 100%, 34.92%, and 31.11%, respectively at the granular activated carbon filter, with very low efficiencies for the removal of TDs and conductivity. Ultra filtration showed average removal efficiencies for COD and BOD of 30.81% and 32.31%, respectively. While the average removal efficiencies for TDs and conductivity was very low. The reverse osmosis filter removed TDs and conductivity very efficiently, giving average removal efficiencies of 97.63% and 95.43%, respectively. In addition, it provided good removal percentages for COD and BOD, with values of 61.73% and 64.1%, respectively. A recycling procedure was created and the results were eventually comparable to those conferred by some of the traditional approaches.
Effect of Heavy Metals on the Activity of Catalase and Glutathione-S-Transferase in Nile Tilapia Fish (Oreochromis niloticus)
Authors: Ha Le Thu , Hoa Bui Thi , Dau Pham Thi
Published: December 2021

This study evaluated the response of antioxidant enzymes, such as Catalase (CAT) and Glutathione-S-transferase (GST) in freshwater Nile tilapia fish Oreochromis niloticus (O. niloticus) exposed to heavy metals (HMs) including copper (Cu), lead (Pb) and cadmium (Cd). Fish were expose to various concentrations of Cu2+, Pb2+ (0, 0.02, 0.05, 0.2 mg/l) and Cd2+ (0, 0.005, 0.01, 0.05 mg/l) for 15, 30, 45 and 60 days. The results indicated that enzyme activity was different according to the exposure time, concentration and type of heavy metals. CAT activity increased significantly beginning at day 45 of HMs exposure. After 60 days of exposure, CAT activity was steady with Cu and Pb but inhibited by Cd. While, GST induction was earlier observed from day 15 of HMs exposure. The increase of GST activity was found with the increase of exposure time in the treatment with Cu and Cd but not with Pb. Interestingly, GST activity was inhibited by Pb at longer exposure (45 and 60 days). Among tested metals, Cu showed the weaker effect on the activity of CAT and GST in comparison with Pb and Cd suggesting that these enzymes were less sensitive to Cu than other tested metals.

Jewish community in Cieszowa in Upper Silesia (1737-1904) and the efforts of Fr. Karl Urban to save its material and spiritual heritage
Authors: Górecki Piotr
Published: December 2021

When in 1908 in Cieszowa, one of the oldest Jewish communities in Upper Silesia, buildings of the dissolved Kehilla were put up for auction, Fr. Karl Urban (1864-1923), the priest of the parish of St. Joseph in Sadów, to which Cieszowa also belonged, purchased a synagogue with the surrounding outbuildings from his own resources, thus protecting them from inevitable liquidation. Cieszowa was one of four villages in Upper Silesia, in which Jews were ordered to reside during Prussian settlement bans, issued in the 1770s and 1780s. The article briefly describes the history of the Jewish community in Silesia, with the emphasis on the religious community set up by them in Cieszowa. In addition, the circumstances of the auctioning of local buildings in 1908 and their purchase by Fr. Karl Urban were described. The author focused on the activity of Fr. Urban, aimed at creating a religious and museum memorial site. Moreover, the author undermines the popular opinion involving the demolition of wooden monuments, allegedly after 1911, postponing the time of their destruction for the years after the death of Fr. Urban, i.e. after 1923.
O entre-espaço ocupado pelo migrante (des)acolhido: entre a hospitalidade e a hostilidade
Authors: Andrade Eliane Righi de
Published: December 2021

Este artigo traz uma discussão teórica a partir dos estudos culturais e decoloniais e alguns resultados da pesquisa empreendida sobre narrativas de migrantes no Brasil, a partir de recortes analisados por meio do dispositivo da Análise de Discurso de linha francesa. É um trabalho de caráter discursivo e interpretativo, o qual busca e discute indícios sobre os processos identitários dos migrantes num espaço entre línguas e entre culturas, a partir das representações de si e do outro (brasileiro), que emergem em seus dizeres. Dessa forma, este estudo pretende contribuir para os estudos da linguagem, identidade e modos de subjetivação, a partir do contexto de migração, no qual a maioria dos estrangeiros ingressantes se encontra em situação de vulnerabilidade. Podemos concluir que esses migrantes recém-chegados buscam formas de resistir e ser sujeito, numa situação nem sempre de hospitalidade, mas de hostilidade, uma vez que o brasileiro nativo, muitas vezes, o vê e o representa como estranho e invasor
Das leis fonéticas à sincronia: percurso e implicações possíveis em Ferdinand de Saussure
Authors: Rocha Raul de Carvalho , Faria Núbia Rabelo Bakker
Published: December 2021

Propomo-nos com este trabalho a discutir os possíveis desdobramentos dos estudos sobre as leis fonéticas para a formulação do conceito de sincronia na Linguística saussuriana. Partindo da premissa de Milner (2012[1978]; 2021[1995]) de que há uma continuidade entre o pensamento de Ferdinand de Saussure e a Gramática Comparada, assumimos a hipótese de que a formulação do conceito de lei fonética no âmbito da Linguística do fim do século XIX permitiu a Saussure conceber a a-substancialidade da entidade linguística e, a partir desta, conceituar a sincronia. Esta é uma pesquisa de natureza teórica dividida entre duas perspectivas de análise: a primeira, externa à obra saussuriana, é voltada para as condições teóricas do saber linguístico disseminado no fim do século XIX, cujo corpus é a clássica obra de Hermann Paul, Princípios fundamentais da história da língua (1880). Nesta, encontramos uma “síntese” das concepções da Escola Neogramática, que constitui o contexto de emergência do pensamento saussuriano; a segunda, interna à produção de Saussure, pretende recuperar os indícios textuais da formulação do conceito de sincronia nas conferências proferidas pelo autor na Universidade de Genebra (1891) e no Curso de Linguística Geral (1916), embora não se limite a estas obras. Concluímos que as reflexões teóricas em torno das leis fonéticas e o tratamento metodológico utilizado pelos linguistas oitocentistas para estabelecê-las encaminharam Saussure para a compreensão da natureza a-substancial da língua e de seu funcionamento sincrônico, e permitiram ao autor fornecer as condições conceituais que autorizam a Gramática Comparada como uma Ciência Moderna
The word classes in Arte da Lingoa de lapam by RODRIGUES João: between tradition and innovation
Authors: Assunção Carlos
Published: December 2021

The main objective of this work is to verify the heritage of the Greek-Latin grammatical tradition in Rodrigues’ Artes and in particular, Álvares’ Artes, and the innovation it brings mainly regarding the description of word classes. To this end, we propose to (i) go through the classifications of the parts of a sentence from the beginning up to Álvares, highlighting the word classes in alvaresian grammar; (ii) to analyze the word classes in Rodrigues’ Artes highlighting those that seem to have new features that the European tradition did not previously consider; and (iii) to draw conclusions.
The Grammatica da Lingua Italiana para os Portuguezes by Antonio Prefumo: between the traditional and the conversational method
Authors: Lupetti Monica , Migliorelli Matteo
Published: December 2021

Within the Italian FL grammatical tradition, the 19th century is a very fruitful period. In other contributions, we have highlighted how several Portuguese and Italian figures connected to the circle of the S. Carlos Theatre in Lisbon act as preceptors and compose some grammars, which contain a strong normative part and, at the same time, connect themselves to the conversational tradition: among these works, the Grammatica da Lingua Italiana para os Portuguezes by Antonio Prefumo (Lisbon, 1829) plays a central role, as it goes through four editions over almost forty years. The paper analyses the social and intellectual context of production of this text, besides outlining the author’s profile and providing a philological reconstruction of the sources and models adopted. Furthermore, the paper attempts an analysis of the Grammatica that, on the one hand, highlights both the heritage of the vernacular and Enlightenment grammatical traditions and its innovative aspects and, on the other hand, compares the various editions through the study of their macro-textual areas. The methodology underlying our description follows that proposed by Swiggers (2006, 168) being based on four aspects: the analysis of the author, the audience, the subject described and its form. This approach places the author at the centre of a historical conjuncture in which the traditional grammatical method was associated with that of conversation, responding to the demand of an audience that increasingly approached the study of FL for practical reasons, rather than to meet the traditional educational demands of the upper classes.

Published: December 2021

Antes del desarrollo de las tecnologías de la información y comunicación, existían narrativas que no solo ficcionalizaban la influencia de las nuevas mediaciones, sino que se inspiraban en el lenguaje del cine para proponer una experiencia sensorial de lectura distinta. Con las tecnologías digitales, esta experimentación literaria se potencializa. La naturaleza y el lenguaje de estas tecnologías han ampliado lo que primero fue imaginado y ensayado en el formato impreso. Para establecer una continuidad entre las apariciones intermediales de la imagen en movimiento en la narrativa impresa y las posibilidades de efectuación de esa intermedialidad en la literatura digital, se examinará la influencia de la estética visual del cine en dos cuentos del uruguayo Horacio Quiroga y una novela corta del colombiano José Félix Fuenmayor. Este análisis también estudiará dos novelas digitales, Pentagonal: Incluidos tú y yo de Carlos Labbé y Lagunas de Milton Laüfer.

Methods. To solve the set tasks, the essence of the organizational and economic mechanism for implementing the state policy of restoring the spheres of life in post-conflict territories of Ukraine was investigated and clarified, the methods of interaction between the government and local self-government bodies with key participants in local development were analyzed and systematized to maintain the efficiency and competitiveness of the region, the organizational and information support of the mechanism was substantiated. As a result of the study, an approach to the formation of an organizational and economic mechanism for the implementation of the state policy for the restoration of the spheres of life in postconflict territories of Ukraine was developed, a feature of which is the transformation of the emphasis on strengthening the institutional framework for creating dialogue, interaction and strong relationships between participants in post-conflict reconstruction from the state and communities in order to overcoming social and economic tensions accompanying post-conflict development. The proposed organizational and economic mechanism for implementing the state policy of restoring the spheres of life in post-conflict territories of Ukraine goes beyond its traditional understanding (with an emphasis on physical restructuring), takes into account the methods, levers and tools aimed at building inclusive institutions, spaces for dialogue between the state and participants in post-conflict reconstruction , the population, which helps to establish the relationship between economic and social life in the peaceful and post-conflict territories of the country, to overcome disproportions and alienation in the process of reintegration of territories into the national economy. The proposed mechanism makes it possible to overcome the economic problems of the affected territories and accelerate their reintegration into the national economy.

Polyphenol Oxidase (PPO) catalyses the undesirable browning of wheat products which is of significant concern in consumer acceptance perspectives. Another important yield-limiting cause for wheat crops is wheat rust (e.g., yellow rust), a source of great economic loss worldwide. The purpose of the current research was to screen conventional and synthetic bread wheat genotypes for their PPO activity and yellow rust resistance. Different genotypes differed significantly in total PPO activity and in their activities against different substrates (L-DOPA and Catechol). The synthetically derived bread wheat genotypes 1-279, showed the lowest (39.2 units/min/g) cumulative PPO activity. Ten genotypes each with the highest and lowest PPO activities were selected for testing their association with seven reported molecular markers. Intriguingly the PPO markers reported in literature could not clearly differentiate between contrasting cultivars. Association with yellow rust resistance was also investigated. Interestingly, the rust-resistant genotypes, including 1-263, Ch-43, 1-57 and Emat (all synthetic-derived), exhibited low PPO activity. The current study underpins that there is a need to search for more reliable PPO markers and to further validate association of low PPO activity with yellow rust.

Development and Application of a Single Neural Network Potential for IRMOF-n (n=1,4,6,7,10)
Authors: Tayfuroglu Omer , Kocak Abdul Kadir , Zorlu Yunus
Published: December 2021

Metal‑organic frameworks (MOFs) with their exceptional porous and organized structures have been subject of numerous applications. Predicting macroscopic properties from atomistic simulations require the most accurate force fields, which is still a major problem due to MOFs’ hybrid structures governed by covalent, ionic and dispersion forces. Application of ab‑initio molecular dynamics to such large periodic systems are thus beyond the current computational power. Therefore, alternative strategies must be developed to reduce computational cost without losing reliability. In this work, we describe the construction of a neural network potential (NNP) for IRMOF‑n series (n=1,4,7,10) trained by PBE-D4/def2-TZVP reference data of MOF fragments. We validated the resulting NNP on both fragments and bulk MOF structures by prediction of properties such as equilibrium lattice constants, phonon density of states and linker orientation. The energy and force RMSE values for the fragments are only 0.0017 eV/atom and 0.15 eV/Å, respectively. The NNP predicted equilibrium lattice constants of bulk structures, which are not included in training, are off by only 0.2-2.4% from experimental results. Moreover, our fragment trained NNP greatly predicts phenylene ring torsional energy barrier, equilibrium bond distances and vibrational density of states of bulk MOFs. Furthermore, NNP allows us to investigate unusual behaviors of selected MOFs such as the thermal expansion properties and the effect of mechanical strain on the adsorption of hydrogen and methane molecules. The NNP based molecular dynamics (MD) simulations suggest the IRMOF‑4 and IRMOF‑7 to have positive‑to‑negative thermal expansion coefficients while the rest to have only negative thermal expansion under the studied temperatures of 200 K to 400 K. The deformation of bulk structure by reduction of unit cell volume has shown to increase volumetric methane uptake in IRMOF‑1 but decrease in IRMOF‑7 due to the steric hindrance.

We disclose novel amphiphilic ruthenium and osmium complexes that auto-assemble into nanomedicines with potent antiproliferative activity by inhibition of mitochondrial respiration. The self-assembling units were rationally designed from the [M(p-cymene)(1,10-phenanthroline)Cl]PF6 motif (where M is either RuII or OsII) with an appended C16 fatty chain to achieve high cellular activity, nano-assembling and mitochondrial targeting. These amphiphilic complexes block cell proliferation at the sub-micromolar range and are particularly potent towards glioblastoma neurospheres made from patient-derived cancer stem cells. A subcutaneous mouse model using these glioblastoma stem cells highlights one of our C16 OsII nanomedicines as highly successful in vivo. Mechanistically, we show that they act as metabolic poisons, strongly impairing mitochondrial respiration, corroborated by morphological changes and damage to the mitochondria. A genetic strategy based on RNAi gave further insight on the potential involvement of microtubules as part of the induced cell death. In parallel, we present a careful examination of the structural properties of these new amphiphilic metal-based constructs, their reactivity and mechanism.
OH binding energy as a universal descriptor of the potential of zero charge on transition metal surfaces
Authors: Kelly Sara , Heenen Hendrik , Govindarajan Nitish , Chan Karen , Nørskov Jens
Published: December 2021

The potential of zero charge (U_PZC) is an important quantity of metal-water interfaces that are central in many electrochemical applications. In this work, we use ab initio molecular dynamics (AIMD) simulations to study a large number of (111), (100), (0001) and (211) and overlayers of transition metal-water interfaces in order to identify simple descriptors to predict their U_PZC. We find a good correlation between water coverage and the work function reduction Δφ which is defined by the difference of the work function in vacuum and in the presence of water. Furthermore, we determine the vacuum binding energies of H2O and *OH species as good descriptors for the prediction of water coverage and thereby of ∆φ. Our insights unify different facet geometries and mixed metal surfaces and thereby generalize recent observations. We further present a scheme to predict U_PZC based only on the *OH binding and the vacuum work function estimated from static DFT calculations. This formalism is applicable to all investigated metals and mixed metal surfaces including terrace and step geometries and does not require expensive AIMD simulations. To evaluate physical influences to U_PZC, we decompose ∆φ into its orientational (∆φ_orient) and electronic(∆φ_el) components. We find ∆φ_orient to be a facet dependent property and a major contributor to ∆φ on (211) surfaces, while ∆φ_sub strongly depends on the metal identity.

How to electrically control magnetic properties of a magnetic material is promising towards spintronic applications, where the investigation of carrier doping effects on antiferromagnetic (AFM) materials remains challenging due to their zero net magnetization. In this work, we found electron doping dependent variation of magnetic orders of a two-dimensional (2D) AFM insulator NiPS3, where doping concentration is tuned by intercalating various organic cations into the van der Waals gaps of NiPS3 without introduction of defects and impurity phases. The doped NiPS3 shows an AFM-ferrimagnetic (FIM) transition at doping level of 0.2-0.5 electrons/cell and a FIM-AFM transition at doping level of ≥0.6 electrons/cell. We propose that the found phenomenon is due to competition between Stoner exchange dominated inter-chain ferromagnetic order and super-exchange dominated inter-chain AFM order at different doping level. Our studies provide a viable way to exploit correlation between electronic structures and magnetic properties of 2D magnetic materials for realization of magnetoelectric effect.

Published: December 2021

The COVID-19 pandemic is a global concern. In this case, Health Care Workers (HCW) are at the front lines in dealing with the pandemic as they provide diagnosis, care, and treatment. However, their duties have directly placed them at the most at risk of infection. Mitigation and risk reduction are crucial for safeguarding HCWs' health as it prevents the spread of COVID-19. This research aimed to find out the practice of COVID-19 prevention and the correlation among practice and knowledge, attitudes, and personality traits of HCW in Palembang. A cross-sectional study was conducted between May and July 2021 on 255 HCW who have direct contact with patients. The number of respondents per hospital is taken proportionally according to the portion of HCW in each selected hospital. The instrument consisted of demographic variables, knowledge, attitudes, and practices. It proves that it is reliable with Cronbach's alpha value of 0.7. The researchers used descriptive statistics, chi-square, and logistic regression. Overall, 65.2% of participants had good knowledge, 60% had a positive attitude, and 53.3% had good practice. Education (p-value 0.022) and attitude (p-value 0.000) of HCW were all influencing factor in practice. HCW who have a negative attitude are 5.413 times more to have bad practices than those who have a positive attitude (p-value<0.001;PR=5.413). However, training for HCW and further research are recommended to analyze the availability of personal protective equipment, adequate facilities, hospital policies, or other factors that can influence and motivate the practice of HCW.

Authors: Коротун Ольга Володимирівна , Марчук Галина Вікторівна , Мєдвєдєв Віталій Володимирович
Published: December 2021

Стаття присвячена проєктуванню та розробці документоорієнтованої системи керування базами даних. Описано компоненти сучасних систем керування базами даних, їх трирівнева архітектура, наведено загальну блок-схему роботи системи. Продемонстровано роботу усіх модулів розробленої системи, зокрема IParseStrategy та IExecuteStrategy. Створено систему парсера, наведено порядок виконання деяких класів, алгоритми роботи компонентів DCL та DDL. Представлено інтерфейс розробленої системи керування базами даних, визначено загальний порядок виконання запиту в ній, показано виконання запитів на створення бази даних та колекцій. Робота з даними в системі керування базами даних дозволяє створювати запити на вставку та редагування даних, їх вибірку та видалення. У системі додатково передбачено можливість виведення даних у файл форматів PDF та Excel. Для операцій, які передбачають поєднання багатьох таблиць, передбачено реалізацію команд Union. Для поліпшення функціоналу до автоматизації в систему введені можливості створення представлень, процедур, що зберігаються, та тригерів на команди. Розроблена система працює з невеликими наборами даних та має низку переваг: невеликі розміри системи, зрозумілий інтерфейс користувача; невеликі розміри коду; утворене абстрактне ядро; обробка регламентних правил через спеціальні об’єкти тощо. Встановлена система підтримки цілісності даних на основі реляційної моделі даних гарантує, що користувач не зможе випадково видалити дані, що використовуються іншими даними. Розроблена система призначена для використання підприємствами малого та мікробізнесу, яким з одного боку потрібна система керування базами даних з підтримкою необхідного мінімуму механізмів контролю цілісності даних, а з іншого – потрібна велика мобільність та зручність використання.

Chlöe Swarbrick’s Auckland Central Victory
Authors: Morgan Huw
Published: December 2021

In the 2020 election, Chlöe Swarbrick won the Green party’s second-ever electorate seat, in Auckland Central. A high-profile candidate, an experienced campaign team, some favourable conditions, and mass engagement enabled Swarbrick to build a winning coalition. For socialists, who are returning to electoral politics throughout liberal democracies, the skills required to win electoral campaigns are key. With an emphasis on ‘building a community, not an army’, the Swarbrick campaign offers useful lessons in how to build and sustain political engagement. With a more explicitly socialist political agenda and a stronger organising theory of change, election campaigns could provide a spark for a left political movement in Aotearoa New Zealand.
Christianity Without Guarantees
Authors: El-Ojeili Chamsy
Published: December 2021

This review essay critically examines Hannah Strømmen and Ulrich Schmiedel’s The Claim to Christianity, an activist intervention that seeks to explicate and contest the theologies running through far-right claims to Christianity. While importantly focused on the semantic struggle for Christianity, refusing to interpret the presence of Christianity in far-right ideology as mere instrumentalisation, and espousing a critical Christianity without guarantees, the book suffers from several analytical and evaluative shortcomings. Framing the object of Strømmen and Schmiedel’s work as a component part of the contemporary post-fascist atmosphere, I suggest that drawing on the work of Ernst Bloch and Antonio Gramsci and attending to the utopian, dystopian, stratified, temporally multiple, and synthetic qualities of far-right claims to Christianity better illuminates the ideological operations of post-fascism and suggests the need for powerful alternative theologies.
The Populist and Institutionalist Logics of Anti-Expressway Campaigns in Aotearoa New Zealand
Authors: Hamlin Morgan
Published: December 2021

This article focuses on the opposition to the New Zealand Government’s Roads of National Significance programme to examine the individualistic and collective forms of political engagement that underpin contestation of expressway proposals and the challenges involved in forming an anti-expressway campaign that transcends locally based opposition. Utilising Ernesto Laclau’s notion of populism, it is argued that, in a post-political planning context, a reliance on an individualistic or institutionalist political strategy can restrain collective action and the development of effective supra-local or national campaigns. The populist and institutionalist logics underpinning the campaigns against the Kāpiti expressway proposal reveal the shared interests between activists and local opposition groups and the potential for progressive forms of populist action on environmental issues and transport policy.
