Published: December 2023

The rapid environmental changes in polar regions have been attracting considerable political, public, and scientific attention in recent years. The polar amplification is recognized as a robust feature of the climate system in response to carbon dioxide (CO2) forcing, resulting in sea ice loss, ice sheet melting, and methane release from permafrost thawing. From a physical perspective, this paper examines the polar amplification and sea ice changes for past and future scenarios using satellite, reanalysis, and climate model datasets. From an interdisciplinary perspective, we discuss the potential environmental, socioeconomic, and political effects associated with these changes. The observational data showed enhanced warming and rapid changes in sea ice cover in polar regions. Under the largest future CO2 forcing, climate simulations indicate an unprecedented rise in air temperature and fast sea ice loss, even in low emission scenarios. This results in a number of physical, environmental, and social-economic effects that need to be carefully considered. Polar climate change, however, offers new opportunities, including the local increase in fisheries and the opening of new navigation routes, which substantially impact the world economy. At the same time, it also implies critical environmental consequences associated with many socioeconomic and ecological risks, such as migration or extinction of populations and species; sea level rise; an increase in frequency and intensity of extreme weather in mid-latitudes; and infrastructure damage from permafrost thawing. Even with the advances and improvements in climate modeling in recent decades, the exact nature of these nonlinear interactions is still in debate.

A agropecuária desempenha um papel econômico crucial no semiárido brasileiro. No entanto, a variabilidade climática representada por esse ambiente desafiador afeta negativamente a produtividade agrícola. Para superar esses desafios, é importante compreender as respostas das culturas ao ambiente de cultivo e adotar práticas de resiliência agrícola. Neste contexto, o uso de modelos, como o AquaCrop, pode auxiliar no planejamento agrícola, identificando os fatores limitantes da produção. Esta revisão bibliográfica buscou explorar a aplicação do modelo AquaCrop para determinar o "Yield Gap" do milheto e do sorgo forrageiro, além de investigar como práticas de resiliência agrícola podem mitigar os efeitos adversos do clima no semiárido. Os resultados indicam que a adoção de práticas resilientes, como a irrigação e a cobertura morta, melhora o desempenho dessas culturas nessa região. Essas práticas também têm o potencial de minimizar os impactos das mudanças climáticas. O modelo AquaCrop se mostra como uma ferramenta valiosa para subsidiar o planejamento dos sistemas de produção de forragem no semiárido, permitindo uma melhor compreensão do "Yield Gap" das culturas e otimizando as tomadas de decisões. Ao adotar práticas resilientes e utilizar o AquaCrop, os produtores podem melhorar a produtividade e a sustentabilidade dos sistemas de produção no semiárido. Em síntese, esta revisão destaca a importância das práticas resilientes e do uso de modelos como o AquaCrop para impulsionar a produtividade e a resiliência dos sistemas de produção no semiárido. Essas informações são fundamentais para orientar estratégias de manejo agrícola mais eficazes e promover a segurança alimentar nas comunidades rurais.

As condições climáticas e geomorfológicas locais refletem diretamente na vegetação ciliar. Apesar de importantes à manutenção dos mananciais, as matas ciliares do semiárido são ainda pouco conhecidas do ponto de vista florístico. Considerando a necessidade de mais dados sobre a mata ciliar no contexto da Caatinga, objetivou-se com este estudo analisar a relação entre a vegetação lenhosa e feições geomorfológico-edáficas em um perfil transversal do rio Groaíras, Ceará. Para isso, foi realizada a caracterização fisiográfica da área, assim como o levantamento florístico do componente lenhoso ao longo do perfil topográfico seguindo o método de caminhamento. As coletas e herborização, realizadas mensalmente entre agosto/2020 e setembro/2021, seguiram os métodos usuais e o material foi depositado no Herbário HUVA. Para as análises, palmeira e demais espécies lenhosas foram classificadas de acordo com a sua origem e distribuição na área. Foram identificadas três feições geomorfológicas, onde se distribuem três fitofisionomias: mata ciliar, carnaubal e Caatinga stricto sensu. A flora lenhosa apresentou 57 espécies, onde 51 são exclusivas ou comuns a um desses subtipos. Diante disso, observou-se que a mata ciliar é floristicamente distinta da Caatinga stricto sensu, mas o carnaubal possui características ecotonais, recebendo influência dos ambientes limítrofes.
High-Quality Evaluation for Invisible Watermarking Based on Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD)

Published: January 2024

. In this research, we propose an innovative approach that integrates Discrete Cosine Transform (DCT) and Singular Value Decomposition (SVD) to enhance the quality and security of digital images. The purpose of this technique is to embed imperceptible watermarks into images, preserving their integrity and authenticity. The integration of DCT allows for an efficient transformation of image data into frequency components, forming the basis for embedding watermarks that are nearly invisible to the human eye. In this context, SVD offers an advantage by separating singular values and corresponding vectors, facilitating a more sophisticated watermarking process. The quality evaluation using metrics such as MSE, PSNR, UQI, and MSSIM demonstrates the effectiveness of this approach. Low average MSE values, ranging from 0.0058 to 0.0064, indicate minimal distortion in the watermarked images. Additionally, high PSNR values, ranging from 67.20 dB to 67.22 dB, affirm the high image quality achieved after watermarking. These results validate that the integration of DCT and SVD provides a high level of security while maintaining optimal visual quality in digital images. This approach is highly relevant and effective in addressing the challenges of image protection in this digital era.

Microhistories of the Crossroad Street films
Authors: Balčus Zane
Published: January 2024

Crossroad Street (Šķērsiela in Latvian) is an 800 m long street in the suburbs of the capital of Latvia – Riga. The street and its inhabitants have been documented in three films by Latvian director Ivars Seleckis over more than two decades. They represent microhistories of people’s lives, which reflect the political and socioeconomic situation in the country over more than two decades (the films were released between 1988 and 2013). The political transformations of the country’s present and past weave through individual destinies, reflecting the deportations of the 1940s, Soviet oppressive politics, the period of perestroika and the awakening of independence, as well as the consequences of joining the European Union, and transiting through the economic crisis in the first decade of the 2000s. The article looks at the characters’ lives where the individual is in constant negotiation of the normative reality as described by Giovanni Levi, and explore their representation in the framework of longitudinal documentaries. Longitudinal documentaries involve revisitations – incorporation of the previously filmed material within a new film, which present an incremental form of narrative (Kilborn), where characters’ lives become “infra-ordinary” (Miller Skillander, Fowler). With each subsequent film, Ivars Seleckis deepens the understanding of the complexity of everyday life in the country in a specific historic period, and presents a multi-layered narrative evolving at the specific location.

Published: January 2024

The deadlocks cutting ritual, known as ‘ruwatan rambut gimbal’ is one of the events in the Dieng Culture Festival which requires the presence of uborampe in its implementation. This study aims to reveal the symbolic significance of the uborampe which share a conceptual similarity with totems. This study uses a qualitative research with a semiotics analysis of Charles Sanders Peirce. The findings of this research indicate that: first, the uborempe presented in the ritual can be called a totem because it comes from animals and plants and symbolizes other sacred things. Second, the people of Dieng Banjarnegara are adherents of limited totemism or quasi totemism, because the totem in the dreadlock cutting ritual is not worshiped but contains an element of expected prayer. Third, forms of syncretism between Hindu, Javanese, and Islam appear in the use of prayer in Javanese and their meaning and offering of uborampe ritual. Fourth, the meaning of the totem in the treatment of the dreadlock cutting ritual in the perspective of Charles Sanders Peirce's Semiotics is categorised in three forms: symbols, icons, and cum icon symbols. The symbolic significance of one uborempe can be manifested in various meanings adjusted to the community that carries out the interpretation.

Decision Analysis to Avoid Unplanned Shutdown and Catastrophic Failure Due to Sour Crude Oil Processing in Crude Distillation Unit (CDU)
Authors: Karnosaputra Yanto , Novani Santi
Published: December 2023

The Crude Distillation Unit (CDU) plays a pivotal role as the primary production unit in crude oil processing. Changes in the operational patterns of crude oil processing have unveiled potential issues that demand the refinery's capability to process Sour Crude. This type of crude oil contains relatively high impurity levels, with a Total Acid Number (TAN) of 0.3 Mg KOH/g and a sulfur content of 1.5 wt%. This has the potential to impact the remaining life and damage modes of equipment and pipes in the Preheater System due to an increase in corrosion rates. This study aims to identify the root causes and propose alternative solutions to address the possibility of damage, particularly leaks, in the Preheater system of the CDU. The focus is on preventing unplanned shutdowns and reducing the risk of catastrophic issues that may arise from the damage to the CDU's preheater system. These steps are crucial to ensuring the continuity of feed supply for secondary processes and valuable product stocks, essential for the operations of Refinery unit. The research employs Fault Tree Analysis (FTA) and Analytic Hierarchy Process (AHP) methods to evaluate several alternative solutions. The analysis results are expected to provide guidance in selecting the most effective and efficient solution, minimizing the risk of preheater system damage, and maintaining the optimal performance of the CDU.

The effect of the acquirers’ market capitalization and payment method on the short-term return of M&As in Greater China and South Korea
Authors: Rijskamp Kimberley Jasmijn
Published: December 2023

Aim: The main goal of this paper is to gain insights into the effect of the market capitalization of the acquirer and the method of payment utilized on the short-term return of the acquiring firm, for deals made between a buyer and target in Greater China (including Hong Kong) and/or South Korea. Additionally, differences between these geographical areas and differences in the acquirer’s industry are analyzed.
Design / Research methods: Data was retrieved from Refinitiv’s EIKON database. A total of 462 deals was obtained and analyzed, using a nested methodology combining elements of an event study with regression analyses.
Conclusions / findings: Acquirers with a small market capitalization obtain either more negative or more positive CARs as compared to large market capitalization acquirers. Secondly, no significant evidence is found that paying a deal using solely cash results in higher CARs as compared to paying a deal fully in shares. Interestingly, it is found that in South Korea paying a deal using shares results in statistically significant higher CARs. Moreover, in China negative CARs tend to be more extreme. Lastly, acquirers operating in the Media and Entertainment industry and in the field of High Technology generate higher CARs.
Originality / value of the article: This paper provides insights into the effects of market capitalization and the payment method in the context of Greater Chinese and South Korean M&As, which thus far have been little studied. Moreover, it uses a nested approach, combing elements from an event study with regression analyses.
METAPHYSICS, ONTOLOGY AND SCENARIOS OF THE GREAT ANTHROPOLOGICAL TRANSITION
Authors: Budanov Vladimir
Published: December 2023

The paper considers the ontological and metaphysical specifics of the beginning of a unique global transition to a post-technogenic civilization, called the Macro-shift. All social, political, economic institutions and cultural practices are going through a crisis phase, and people’s worldview and values are radically changing. Ethics becomes the main behavioral parameter of order, as it always happened in the era of trials, and the revival of the tradition of inner life is almost the only factor in human adaptation to external chaos, without loss of human appearance. The metaphysics of the Macro-shift, which distinguishes it from the previous crisis epochs, is connected not only with the general planetary character, but, first of all, with the completion of the pre-singular development of human history. The demographic planetary singularity is already being overcome by slowing the growth of the number of people. We acutely feel other forms of singularity as the acceleration of all processes in all forms of social, cultural, economic and informational life, immersing us in a super-complex reality. The singularity itself, when the multithousand- year-old laws of the development of the socio-technoanthroposphere should change, falls in the middle of the XXI century and has no analogues in past history. This does not allow us to build predictive models of the future, creating a time of hyperdeterminacy. It turned out that the singularity coincides with the stage of completion of the historical cycle of the development of human cognitive abilities. It is also shown that Artificial Intelligence is not only a catalyst for ultrafast changes, but also a possible tool for passing the super-complex singular phase of the Macro-shift. The genesis of the phenomena of digitalization and AI as the results of the co-evolution of natural, social, virtual and technical umwelts in the process of successive information revolutions is considered. In this connection, the problem of existential challenges in the anthroposphere, the problem of demarcation of the areas of responsibility of natural and artificial intelligence, the problem of post-critical rationality and the coexistence of human-machine hybrid forms of life is raised.

Published: December 2023

Este artículo tuvo por objeto analizar las principales consecuencias de la pandemia por COVID-19 para la competitividad en la Alianza del Pacífico, frente a los objetivos propuestos por esta integración regional, considerando los impactos a corto, mediano y largo plazo. Se empleó un enfoque cualitativo con un alcance interpretativo, diseño no experimental y transversal. Se recopiló información documental sobre estrategias, decisiones y resultados de los principales objetivos estratégicos en las organizaciones de los países firmantes: Chile, Colombia, Perú y México. Se encontró que la incidencia del COVID-19 provocó importantes efectos en la infraestructura, innovación, tecnología y eficiencia operativa. Como consecuencia de dichos efectos, también ha acelerado la adopción de tecnologías 4.0 y modelos de trabajo remoto en diversos sectores, lo que ha llevado a la implementación de políticas para estimular la reactivación de la economía. En este contexto, la Alianza del Pacífico promueve la recuperación económica y fortalecer la integración regional; sin embargo, el acuerdo ha enfrentado desafíos dada la disminución del comercio internacional y la vulnerabilidad derivada de aumento de los precios en materias primas. Se concluye que la reactivación económica requerirá la atención de los gobiernos en los sectores más afectados y la diversificación de las relaciones comerciales con múltiples países y regiones.
Queer Reproductive Decision-Making in Saskatoon
Authors: Jack Jessica
Published: December 2023

This article is a plain writing summary of a master’s thesis researched and written in the Department of Archaeology and Anthropology at the University of Saskatchewan between 2020-2023. This thesis examined how eighteen queer people living in Saskatoon, Saskatchewan made their reproductive decisions during the COVID-19 pandemic by asking what meanings do queer people in Saskatoon find in their reproductive decision-making processes, and how do those meanings influence those processes during the COVID-19 pandemic? Three themes emerged from these interviews. The first was how queer family structures are formed, including an analysis of the nuclear family and the ways that approach does or does not work for queer families and the gendered problems queer people face when contemplating pregnancy. The second centres on safety, with people born and raised in Saskatchewan prioritizing social safety and people born in different, sometimes less queer-supporting countries prioritizing physical safety when making reproductive decisions. The third is the relationship between COVID-19 and place, dissecting how the COVID-19 pandemic has changed the meanings of place through social distancing and isolation, and how the space between places (i.e., travel and remote connection software like Zoom) has changed meaning during this pandemic. This research has implications for informing institutional responses to Canada’s declining population levels and to better support queer people in making their reproductive decisions.
Religion and Revolt
Authors: Guliak Dasha
Published: December 2023

Despite the scarce research on the topic the eight-year Tithe War represents an important moment in the development of Irish-Catholic nationalism and a pivotal change in Irish-British relations. This investigation into the Tithe War uses discourse analysis to reveal how Irish-Catholics exerted an intense degree of agency against the Anglo-Protestant ascendancy during a time in which they possessed seemingly little recourses against the increasingly hegemonic powers of the British state. Understanding the importance of the Tithe War helps to develop a deeper understanding of Irish-British state relations within the larger timeline of Irish-British relations into the twentieth century. The Tithe War also demonstrates the role of religious identity in shaping collective action and nationalism. This paper highlights how the violence of war grabbed both media and government attention and led to the gradual disestablishment of the Anglo-Irish Protestant Church in 1869. This short article provides insight into the actions of everyday Irish-Catholics and how their actions led to critical changes in Irish-British relations. It also highlights how the British media and British officials understood, disregarded, and navigated the increasingly hard-to-ignore “Irish problem.”

This paper begins with a vignette to situate the reader in the landscape of the Woodlawn Cemetery and gain a better context for the analysis that follows. Through primary and secondary research, the Woodlawn Cemetery reveals the ways that temporality, power, and culture are reflected in this deathscape. Historical records of the Woodlawn Cemetery support the argument that temporality is being realised in the landscape in a linear way, here, time is an important part in shaping the landscape. The concept of memoryscapes, which involves spaces of memory, show that the connection of nonlinear time also exists within deathscapes, specifically within the Woodlawn Cemetery. Power is imbued in the landscape of the Woodlawn Cemetery through burials. Burials in this deathscape serve as powerful symbols of control when considering concepts such as necro-colonialism and the establishment of war monuments. Through methods such as walking the land there are other overt displays of power at the Woodlawn Cemetery that reflect the ownership of the land and governance of access imposed by the City of Saskatoon. This paper focuses on how aesthetics are used to manipulate emotions and ease the discomfort of confronting death and create a sense of familiarity for Euro-Canadians. An analysis of the surrounding landscape and changing attitudes toward death through time support the idea that death is not something to be looked upon by everybody as it has been deemed a private affair.
Connecting Humans and Non-Humans
Authors: LaBrie Katie
Published: December 2023

A recent trend in public health campaigns has been to include non-human health data to capture all relevant variables related to human well-being. This specific approach is the foundation of the World Health Organization restructuring in the early 2000s as they adopted the “one health” framework. Politically, this movement is influential and draws significant health funding globally. "One health" is characterized by a multi-disciplinary collaboration between medical, veterinary, and health sciences. Similarly, the post-human turn in medical anthropology recognizes that viewing the non-human contributions to the cultural construction of health as symbolic does not adequately address how non-humans and nature independently contribute to human health realities. Ethnographic studies of the non-human perspective shed light on how humans are not the only beings that influence culturally constructed reality, nor are they exclusively in control of cultural phenomena. Theoretical trends in anthropology and public health seemingly converge; however, an artificial academic barrier between the sciences and social sciences remains. As these two disciplines are coming closer together through their data, breaking down structural barriers that prevent the successful integration of knowledge has potential to improve human health outcomes. Methodological concessions will have to occur on all sides to make the inclusion of the social sciences in public health possible. Doing so can bring academia closer to a comprehensive scientific understanding of human health.

Firm financial performance has remained a focus for all firms. The findings of various studies on the relationship between shareholder activism and market value, dividend policy and market value and corporate social responsibility disclosure have conflicting results. Some findings show that there is a significant positive relationship. Others show that there is negative relationship. Others posited no relationship. These results are confounding necessitating further research to establish the relationship between Dividend policy and market value. The study objectives included to investigate the relationship between shareholder activism and market value, to determine the mediation effects of dividend policy on the relationship between shareholder activism and market value; and to determine the moderated mediation of corporate social responsibility disclosure on the relationship between shareholder activism and market value. The study adopted panel data design. The sample size was 54 firms listed at Nairobi Security Exchange (NSE). Data was gathered for the period between 2008 – 2017. Results revealed that dividend policy had no significant effect on market value, b1 = 3.6, p>.05; shareholder activism had a positive and significant impact on market value,
Household Income Diversity: An Antidote to Poverty Eradication in Developing Economies
Authors: Alex Watema Joash Robert
Published: December 2023

The acceptance of economic variability by households is seen as a key step towards escaping the poverty
cycle. The purpose of the study is to examine the link between household wellbeing and income diversity
empirically. Using instrumental variable static panel model regression, we investigate the implications of
probable indigeneity caused by selection bias. The study made use of the waves from the Uganda National
Panel Survey. The findings show that having a diversity of revenue sources greatly enhances household
wellbeing. The results also showed that residing in the eastern or northern areas had a negative impact on
welfare compared to living in the center region, and that household welfare is substantially predicted by
the education of the household head. The subjective aspect of wellbeing could not be fully described by the
methodologies used in this study. Future research could think about using a practical strategy. The use of
both primary and secondary data for additional investigation might provide astounding findings. The
research study adds to the welfare literature by showing the influence of income variety on household
welfare as defined by poverty status and consumer spending, in contrast to other studies that simply
examined expenditure as a proxy for welfare. By demonstrating how income variety improves household
wellbeing using a sample of homes in Uganda, a developing economy, the study furthers the welfare
theory
Uzaktan veya Hibrit Çalışanlarda İş Yaşam Dengesinin Duygusal Tükenmişlik Üzerindeki Etkisinde Erteleme Davranışının Rolü

Published: December 2023

Dünya genelinde yayılım gösteren Covid-19 virüsü toplumların farklı alanlardaki uygulamalarına
ilişkin çeşitli değişiklikleri beraberinde getirmiştir. Bunlar arasında en çok hissedilenler, ekonomiler, iş
yaşam dengeleri ve bireylerin psikolojik durumlarındaki değişiklikler bulunmaktadır. Bu çalışmada
değişen çalışma dinamikleri özelinde hibrit veya tamamen uzaktan çalışan bireylerin erteleme
davranışına bağlı olarak iş yaşam dengesinde gerçekleşen değişiklikler incelenmiş olup, bunun
duygusal tükenmişlik üzerindeki etkileri ele alınmıştır. Uzaktan veya hibrit çalışma modeliyle
çalışmakta olan bireyler araştırmanın evreni olarak belirlenmiştir. Araştırma için kullanılan örneklemde
uzaktan çalışma sistemlerinin büyük şehirlerde daha yaygın olması sebebiyle ağırlıklı İstanbul olmak
üzere Ankara ve İzmir illerinde belirtilen çalışma modellerine sahip bireyler üzerinde İş-Yaşam
Dengesi, İşi Erteleme Davranışı ve Duygusal Tükenmişlik ölçekleri, toplam 5 aylık süre içerisinde 261
çalışana uygulanmıştır. Bu çalışanlar arasında yapılan uygulamada 58 kişi ofisten çalıştığı için
değerlendirmeye alınmamıştır. Yapılan analizler sonucunda iş yaşam dengesindeki bozulmanın
bireylerin tükenmişlik düzeyinde etkili olduğu görülmektedir. Tükenmişlik durumunun da bireyde
başarısızlık hissi, duygusal tükenme ve zaman içerisinde duyarsızlaşma etkilerinin olduğu sonucuna
ulaşılmıştır.

Metody wzbogacania na sucho były popularne w pierwszej połowie XX wieku. W latach trzydziestych XX wieku, przed II wojną światową, istniały separatory do wzbogacania na sucho używane najczęściej w Stanach Zjednoczonych. Obecnie metoda ta jest bardzo popularna w Chinach, Stanach Zjednoczonych, Indiach, Rosji. Z kolei w Polsce separacja na sucho jest nadal rzadkością. Jednak w ciągu ostatnich 30 lat w procesie wzbogacania węgla zaczęto coraz częściej stosować separatory na sucho. Jednym z przykładów tego typu separatora może być separator wibracyjny powietrzny FGX. Ten typ separatora wykorzystuje zawieszenie pneumatyczne do oddzielania cięższych cząstek (odpadów poflotacyjnych) od lżejszych ziaren węgla. Proces separacji na sucho może zależy od różnych parametrów, takich jak: wielkość cząstek, dopływ powietrza, parametry nadawy, itp. W artykule przedstawiono model matematyczny separacji na sucho węgla. Modele matematyczne opierają się na zależnościach pomiędzy wartością opałową a zawartością popiołu w badanych próbkach oraz zależnościach pomiędzy zawartościami arsenu, talu, rtęci, ołowiu i innych właściwości węgla. Te ostatnie parametry mają istotne znaczenie, gdyż polskie normy emisyjne nie zawierają limitów dla wyżej wymienionych pierwiastków (arsen, tal, rtęć i ołów).
