Crystalline materials in art and conservation: verdigris pigments – what we know and what we still don’t know
Authors: Bette Sebastian , Eggert Gerhard , Dinnebier Robert E.
Published: June 2023

Verdigris is a collective term for synthetic copper based green and blue pigments that have been used by mankind since the antiquity. As the term is only loosely defined it covers a great variety of chemical compounds. All of them contain copper but also acetate, formate, hydroxide, water and sometimes also chloride, carbonate and sulphate. This article focusses on the verdigris phases related to the ternary system Cu(CH3COO)2–Cu(OH)2–H2O, which are commonly denoted according to their chemical composition as x–y–z phases. Besides neutral verdigris (1–0–0 and 1–0–1 phase), several basic verdigris
phases (2–1–5, 1–1–5, 1–2–0, 1–3–0, 1–3–2, 1–4–3, 7–1–4) have been reported. These compounds can be obtained either by intentional corrosion of copper metal by direct contact with acetic acid and its vapours, which represents the historic pigment manufacturing or by incomplete precipitation from copper(II) acetate solutions. Due to their slow crystallisation behaviour the synthesis of verdigris pigments usually leads to multiphase and polycrystalline samples, which impedes the phase characterisation, in particular of the basic verdigris samples. Hence, most crystal structures that have been published were solved ab-initio from X-ray powder diffraction data by applying global optimisation methods like simulated annealing or charge flipping
. Up to now the crystal structures of the 1–0–0, 1–0–1, 1–3–2, 1–2–0 and 2–1–5 phases were determined, the spectral and physical properties of these compounds completely characterise and therefore their existence and their chemical composition unambiguously proven. Investigations on historic verdigris samples and systematic synthesis approaches, however, show that there are at least four additional, hitherto unknown pigment phases. Information on the thermodynamical stability and the solubility of the verdigris phases are also lacking.
Visualizing Hope Through Black Children’s Multimodal Messages Reflecting the Multiple Pandemics
Authors: Barton Reka , Cappello Marva
Published: June 2023

We are still dealing with multiple pandemics including COVID-19, which disproportionately affects minoritized people, as well as significant incidents of police brutality directed toward Black people. The purposes of this study are to visually document these multiple pandemics from our Black children’s perspectives as well as elevate their visual texts to advocate for hope and change. This article highlights the ways 13 Black elementary school children drew out their ideas to depict this critical time. We believe studying how children witness crises is essential for documenting history, especially when Black children’s voices do not rise above white mainstream messaging. The research question guiding our study asks, how do elementary-aged Black children visually represent this critical time in history? Findings suggest that our Black elementary-aged students not only were successful at creating visual texts that document this historical time but also that their drawings reflected hope and social change.
“A Hand to Your Darkness”
Authors: Wilson Emma
Published: June 2023

All the Beauty and the Bloodshed is Poitras’s first portrait of a female subject. In it for the first time she models forms of feminist attention to another woman, a woman artist, speaking and listening to her. Through openness to Goldin’s susceptibility, experimentation, pleasure, and suffering, Poitras addresses trauma and its relation to activism. In their collaboration, Goldin brings the visual sublime as well as overt sensuality into Poitras’s purview, releasing the eros and pathos that have always been part of her work. In turn, Poitras makes possible, and essential, a full portrait of Nan Goldin as activist.
Bellocchio’s Histories, Personal and Public
Authors: Forgacs David
Published: June 2023

In The Traitor (2019) and Exterior Night (2022), Marco Bellocchio revisits traumatic and violent episodes in Italy’s recent past. The first is a feature film about the round-up of Sicilian mafia members in the 1980s and their retaliatory attack on the Italian state. The second is a six-part television series about the abduction and murder in 1978 of politician Aldo Moro as lived by his family, political colleagues and the terrorists who captured him. Bellocchio’s nonfiction Marx Can Wait (2021) also evokes a trauma, in this case a personal one: the legacy of his twin brother’s suicide in 1968 on himself and his family. This article examines Bellocchio’s techniques of incorporating archive images and footage, including from his own earlier films, as well as his use of dream and fantasy sequences, as ways of situating himself as an older man in relation to that past and of processing traumatic memories.

God’s Wrath over Antioch, 525–540 CE
Authors: Borsch Jonas
Published: June 2023

Ancient Antioch (modern Antakya) is well known as a city prone to disasters. However, the calamitous events that hit the city between 525 and 540 CE have attracted particular attention. Within a time span of fifteen years, Antioch suffered major destructions by two massive earthquakes, several conflagrations, and a Persian sack. These events are reported in highly dramatic accounts by John Malalas and Procopius. Based on such reports, scholars since the nineteenth century have often interpreted these disasters as the starting point for a general decline of the city beginning in the sixth century. More recent reassessments, in contrast, have highlighted continuities on a variety of levels, emphasizing that over the long term, Antioch displayed high resilience on structural and institutional levels. This article picks up on these more recent findings but strives to approach the subject from a different angle. It focuses on Malalas’s and Procopius’s influential disaster narratives and seeks to further contextualize them. It traces how modern scholarly reception of the literary sources has fostered the traditional picture of “decline,” and it analyzes the narrative strategies of the texts, considering the literary traditions from which they originate and the cultural setting of which they form a part. The article seeks to show that the late ancient reports aim not to establish a picture of decline but rather to present Antioch as a purified, freshly Christianized city emerging from the ashes. It further argues that while it is important to critically reflect upon the rhetorical character of the double narrative of heavenly destruction and recreation, exploring the question of Antioch’s urban development in the sixth century through the lens of contemporary discourse on the Christian city not only increases our sensitivity to the methodological problems connected to these texts but may also lead to a better understanding of our evidence on Antioch’s post-Roman development.
Imperial Crisis Response and the Antiochene Magic and Treason Trials of 372 CE
Authors: Langenfeld Kathryn A.
Published: June 2023

The writings of Ammianus Marcellinus, Libanius, and John Chrysostom have enshrined the Antiochene treason and magic investigations conducted under Emperor Valens in 372 CE as a testament to the ruler’s excessive paranoia and poor relationship with the eastern metropolis. By reexamining these three authors’ allegations of judicial corruption and abusive policing during the trials, this article contends that Valens’s response to the crisis was leveraged with far more legality, moderation, and success than often discussed. The rigorous tactics implemented during the trials demonstrate Valens and his administration’s intent to counter potential sedition among Antioch’s citizenry with the full brunt of Roman law and military action. Comparisons with legal precedents reveal, however, that Valens’s administration balanced these stern deterrents with deference to the law and attempted to assuage Antiochene interests throughout the investigations. Antiochene lobbying efforts were also more impactful in mitigating the imperial response, as demonstrated by Chrysostom’s account of a public protest that successfully petitioned Valens to pardon one of the accused. This article concludes that this pardon and Valens’s application of moderated or commuted sentences throughout the trials indicate his efforts to maintain a constructive imperial-urban relationship with the Antiochene populace. This conclusion not only forces a reconsideration of Valens’s relationship with his de facto imperial capital throughout the trials but also indicates the dangers of relying too heavily on literary interpretations of Valens’s reign.

Authors: Pitria Meidesta , Andari Yuni
Published: June 2023

Urbanization does not only affect land use in urban areas but also in rural areas. Many lands in rural areas are vacant. Although placemaking is often associated with urban contexts, its role in rural areas has emerged. Placemaking is believed to improve the economic and social aspect of vacant land uses. This study aims to analyze the process and impacts of rural placemaking in transforming vacant land into an attractive public area with a case study in Pasar Papringan, Ngadimulyo Village. This study was conducted by qualitative approach through in-depth interviews with six respondents and by quantitative approach through distributing questionnaires to a total of 61 respondents. The results show that rural placemaking not only activates vacant land, but also improves economic and social capitals. The perception regarding the economic impacts revealed that most respondents agreed that placemaking had the highest impact on innovation and the creative economy, particularly in supporting the creative economy (30 respondents, 49%). While the perception regarding the social impacts revealed that placemaking had the highest impact on their well-being, such as healthy lifestyle (41 respondents, 67%). The results of this study are expected to provide recommendations for vacant land management through rural placemaking practices.
Monetary Policy and Trade: An Engine for Economic Growth
Authors: Arifin Samsul
Published: June 2023

Amidst on the debate of the trade openness (TO) importance in influencing an economic growth (EG) and the central bank policy rate (CBPR), it is necessary to analyze the long-term relationship by using ARDL. This paper aims to analyze the CBPR and TO influence on EG in ASEAN  -3. This study examines the EG model which focuses on the effect of CBPR and the ratio of exports in which plus imports divided by GDP as a measure of TO in ASEAN-3. The Data was collected from IFS for Indonesia, Philippines and Thailand for the period 2007q1-2022q2. The ARDL test method is used to determine the long-term relationship among the EG, TO and CBPR variables with different degrees of the integration. The FMOLS, DOLS, and CCR testing is for check robustness. The study show that CBPR has a positive effect on the EG in ASEAN-3, although it is only in Indonesia, and in Philippines which is statistically significant. The TO positive effect on the EG in Indonesia and in Thailand, but it is not significant and it has a TO statistically significant negative effect on EG in Philippines. The importance of this research given the recent interest in globalization activities, so the role of TO has become very important. A better TO understanding whether import dominance or vice versa helps in understanding the impact of globalization on the country economy. This finding emphasizes on the export importance over the imports in the economy. However, there is not an academic research looks at the long-term relationship between monetary policy and trade openness on the economic growth with the various econometric models.
Village Development: Effect of Vilage Fund and Village Head Education
Authors: Nadia Anggun , Mahi Benedictus Raksaka
Published: June 2023

Village Autonomy allows villages to realize more advanced and prosperous rural development. According to some literature, village development needs sufficient funds. In Indonesia, Village Fund has become one of the necessary funds for villages since 2015. Besides the effect of the Village Fund amount, this study evaluates the role of village leaders in optimizing Village Fund management. This study aims to analyze the impact of village head education support in managing the Village Fund on the development of village status in Indonesia empirically. The analytical method uses cross-sectional multiple linear regression in the data between 2018 and 2020. This study uses changes in the village building index (IDM) score to reflect the development of village status each year as the dependent variable, then Village Fund and interaction between Village Fund and Village Head education as the independent variables. The results denote that the management of the Village Fund will be more effective in influencing the growth of village development if the village has a village head with an education above high school. Therefore, the Central Government should provide intervention on the policy criteria for allocating Village Funds, especially performance allocation, by including village head education as an additional indicator in the Village Fund management process.
River Bank Analysis in the Vicinity of Sebatik Island and Its Influence to Determine Boundary of Indonesia-Malaysia
Authors: Jati Ardiawan , Pratomo Danar Guruh
Published: June 2023

River as the boundary is listed in the 1915 Netherland-British Agreement with its Annex Map without any clear coordinates. This is an obstacle in tracing boundaries in the real river because where river is dynamic, changes in the river shape and river bank can occur in more than 100 years. Multi-temporal Landsat satellite imagery processed with a combination of bands (color composite) is used to observe the position of the river bank from 1989 to 2019 with visual interpretation and manual digitization. As a result, over 30 years there was a shift in the Sikapal river bank with an average of 11.4 m on the right side (Indonesia) and 15 m on the left side (Malaysia). The average shift of the Tamboe river bank is the right side 25.1 m and on the left side 8.8 m. The shift is relatively small because around the Sikapal and Tamboe rivers banks are overgrown by mangrove forests which can slow down the rate of erosion. River banks in 1989, 1999, 2009 and 2019 were used as a basis for delimitation of the Indonesia-Malaysia boundary using a three-stage approach. As a result, there are differences in the shape of the boundary line although it is small. However, the river area of Indonesia and Malaysia still has a proportional ratio of 1: 1.03 in 1989, 1999, 2009 and 2019. Although the ratio is the same, the area of the river has increased by 0.08-0.11 km2.

Authors: Kibirige Israel
Published: June 2023

Learners bring various misconceptions to class. The study explored learners’ misconception prevalence about heat and temperature among Grade nine Natural Sciences learners. A single case study design with 30 Grade nine learners from one secondary school in Magatle Circuit. The Heat and Temperature Concept Questionnaire (HTCQ) was used to elicit learners’ misconceptions. For each questionnaire item, percentage frequencies of incorrect, correct, and unanswered responses were calculated. The overall prevalence of misconceptions regarding heat and temperature among learners ranged from 40 to 93% (Mean 68.0% SD = 6.3), with the highest prevalence in thermal dynamic questions. The correct responses ranged from 0 to 57% (Mean = 25.1, SD = 7.1) where most learners scored between 20-30%, while unanswered questions ranged from 0 to 13% (Mean = 6.9, SD = 1.3). These results show a high prevalence of misconceptions. They could not explain how heat travels within molecules of different objects because of the lack of a link between every knowledge and school science. The findings of this study have several implications for classroom planning, teaching, and the designing of learning materials.

Published: June 2023

This paper investigated the impact of the Nurturing talent in Science, Engineering and Technology (NSET) programme on teaching practices in rural schools within the Nkowankowa cluster in the Limpopo Province. Though NSET programme focused on Science, Mathematics and Technology, this study will only concentrate on Physical Sciences. Out of the population of 68 Science teachers, 30 participated in the completion of questionnaires and nine were interviewed. A mixed-methods approach with an exploratory design was used in this study to investigate the impact of the NSET programme on learner performance in Physical Sciences (focusing on teacher content and pedagogical delivery). For learners to consistently perform better, then one need to focus on teacher development in terms of content and pedagogy. The model that focuses on teacher development in order to address the performance of learners helps to sustain better results at school than focusing directly on learners since the teachers are likely to interact with more learners and stay at the same school longer. Questionnaires, interviews and document analysis were used as data collection methods. According to the research findings, the NSET programme had a positive impact on both the content and pedagogical delivery of teachers. This was revealed through the confidence educators gained and their ability to come up with new teaching strategies and improved teaching practices. The positive impact of the NSET programme is also noted through learners’ improved academic performance in Physical Science. The NSET programme conducted within the Nkowankowa cluster yielded positive results and the Limpopo Department of Basic Education (DBE) can adopt it as one of the best practices in the development of teachers and improvement of results in their schools.

This study aims to examine the role of traditional horse racing games in the tribes of the Dompu tribe, Indonesia. This study uses a qualitative approach with ethnographic methods. The subjects of the study were five young jockeys aged 4-8 years and seven horse owners. Data were collected through observation, interviews, documentation and focus group discussion (FGD). Data were analyzed using domain analysis techniques, taxonomic analysis, componential analysis and theme analysis. The results of the study indicate that the transformation of enviromental education in early childhood through horse racing games is done by growing children's concern for the environment and caring for animals, such as horses. During the process of horse racing, children are not permitted to damage nature and hurt animals. Therefore, horse racing becomes a means of enviromental education for children for the sake of the preservation of nature. Horse racing is also one of the most environmentally cared tourist destinations for local people. Another important finding is that the traditional horse racing game in the Dompu tribe has become a medium of transformation of enviromental education of for early childhood. This study informs that the transformation of environmental education can be done since children are aged 4 years through traditional horse racing games. This research can also be a reference for early childhood education practitioners to create a special school for children who have a hobby of riding horses.
