Published: May 2023

Osteochilus spilurus is one of the native fish in Indonesia. This species from North Lampung has variations in body shape with populations in Bangka and Belitung. Morphological plasticity and genetic variation are potential causes of these differences. To confirm this, it is necessary to identify molecular using the mitochondrial cytochrome b (cyt b) gene. Fish samples from North Lampung had morphological characters that matched to the description of O. spilurus. This research specimen was registered at the Bogor Zoological Museum as a supplementary note from Lampung. The phylogenetic construction shows a closer relationship between fish samples from North Lampung and O. spilurus from Bangka-Belitung, but there is a wide genetic distance between them. Genetic variation between islands that occur is predicted due to differences in ancient river flows in the past and the geographical isolation of the oceans for thousands of years.Keywords: Cytochrome b; Lampung; Osteochilus spilurus; Genetic Variation

Authors: Setyastuti Aryanti Indah , Ayu Rr. Nurina , Sarmin Sarmin
Published: May 2023

Smoking is one of the efforts to maintain the quality of smoked fish. Phenol compounds in smoke can act as natural antioxidants to inhibit lipid oxidation. Milkfish have a high lipid content after protein, which can undergo lipid oxidation during processing and storage. The aim of this study was to observe the effect of antioxidant activity on different smoking methods and storage time for 28 days at freezing temperature on the quality of smoked milkfish. Corn cob liquid smoke was used due to phenol content as an antioxidant. The design used in this study was a factorial completely randomized design that consisted of two factors. The first factor is the difference in smoking methods, corncob liquid smoke (Ac) and Traditional (Tr). While the second factor is the length of storage on day 0 (T0); day 14 (T14) and day 28 (T28). The test parameters observed were analysis of phenol content; PV; TBA; lipid content; and pH. The results of this study showed that different smoking methods and storage time at freezing temperature showed significant differences (P<0.05) in the phenol value; PV; TBA; lipid value; and pH of smoked milkfish. During storage, the phenol value; lipid; and pH of smoked milkfish decreased. Meanwhile, the value of PV and TBA increased as a result of the lipid oxidation process so as to produce peroxide from detheorized fat. The PV and TBA values of smoked milkfish are still acceptable by consumers.Keywords: Antioxidant acticvity; Corncob liquid smoke; Milkfish; Traditional

In conclusion, it is proved that the improving effects of 8 hour priming of sunflower seeds with TiO₂ NPs solutions on sunflower seedling emergence.
Carbon-based Materials for Sustainable Energy Innovations: Recent Advances and Future Challenges
Authors: Sari Yusuf Andi Asdiana Irma , Taspika Melda
Published: May 2023

Sustainable energy is essential to reduce fossil fuel consumption. However, sustainable energy development still faces many problems that make its progress insignificant in the last decades. Alternative energy sources are needed to minimize fossil fuels (coal, natural gas, and petroleum). Biomass and carbon fullerenes are a choice, but their innovation technologies are still restricted to pilot-scale production in the laboratory. Biomass is a climate-neutral energy source, but the CO2 emission of biomass combustion is inevitable, indicating the importance of innovative methods in processing biomass to energy. Different methods (thermochemical or biochemical) will produce different carbon footprints. Besides, biomass development also requires innovative small-scale technology to generate affordable energy for citizens and communities. Carbon fullerenes have been applied for energy applications, especially capacitor and lithium-ion (Li-ion) batteries. Up today, progress in Li-ion battery manufacturing moves at a slower pace and not much progress. The significant problems of Li-ion batteries are volume expansion, low electric conductivity, and inappropriate coulombic efficiency. Carbon-based fibers such as carbon nanofibers, CNT-based fibers, and graphene-based fibers have been used for capacitors, but there are still many obstacles, such as a lack of knowledge to solve capacitor self-discharging. Therefore, research and development of carbon-based materials are urgent energy innovation developments.

Each region has different potential resources. These potential differences will also affect the different characteristics of the economy in each region. A typical mindset thinking Bali as a tourism center briefly provides an overview of the basic sectors found in each region, including Denpasar. Apart from the tourism potential of Denpasar, it is important to identify the basic and non-basic sectors. In the midst of the Covid-19 pandemic, it is very likely that the existing economic structure will change. The identification of basic and non-basic sectors can be used as a reference in maintaining the economy so that other superior potentials can be maximized. This study aims to: (1) analyze basic and non-basic sectors in Denpasar City, (2) analyze the multiplier effect of basic sectors in Denpasar City, and (3) analyze basic sectors in Denpasar City in the middle of Covid-19 Pandemic Era. The results show: (1) There are nine basic sectors and three non-basic sectors of the twelve economic sectors which were analyzed based on Denpasar City GRDP data during 2016-2020. (2) The value of the multiplier effect of Denpasar City is 0.31. This means that the PB value for income is 0.31, so every increase in one unit of the basic sector will result in a 0.31-fold change in income for Denpasar City.

CHINA’S ECONOMIC PRESENCE IN CENTRAL ASIA: KAZAKHSTAN CASE
Authors: ÇELİK Yavuz
Published: May 2023

Since the dissolution of the Soviet Union, China has significantly increased its economic presence in Central Asia thanks to leading Chinese institutions such as the Shanghai Cooperation Organization (SCO), the Belt & Road Initiative (BRI), and the Asian Infrastructure Investment Bank AIIB. Now on the course, China is one of the most significant partners for Central Asian states. China has opened up to private business and foreign investment. State-owned banks turned saving into financing infrastructure facilities such as roads and rail links. Foreign firms were asked to set up alongside a local partner, encouraging to transfer of technology. For decades, as a result, China's economy has grown. This paper will focus on Kazakhstan as a case country in Central Asia. Diplomatic ties between Astana and Beijing developed shortly after the collapse of the former Soviet Union, with both countries moving on to co-found the Shanghai five, which later turned into the SCO. From Kazakhstan's point of view, the country's geopolitical situation leaves it no choice but to cooperate with Russia and China, Kazakhstan's two most potent and closest neighbors. Currently, Kazakhstan's strategy provides the path to China's economic outreach, while Beijing's growing investments provide Kazakhstan's path to modernization. Kazakhstan and China have extended their diplomatic ties since 1991, and since the launch of the BRI in 2013, they even furthered their economic relations are thriving. Financial integration is vital to supporting the BRI; therefore, the AIIB was established. Along with the significant growing economic influence, two main challenges require feasible solutions one is the Russian reaction to China's growing economic presence, and the other is the anti-Chinese sentiment that causes demonstrations in Kazakhstan.

V. E. Adodurov – the theorist and practitioner of teaching Russian as a foreign language in the first half of the 18th century
Authors: Papilova Elena Vyacheslavovna
Published: May 2023

This article is devoted to the practice of teaching Russian as a foreign language in the middle of the 18th century. As an example, the activity of Vasily Evdokimovich Adodurov, a member of Petersburg Academy of Sciences and the Russian grammar theorist, is used. Adodurov was not merely a theorist as the author of one of the first written tutorials in Russian as a foreign language (“Anfangs-Gründe der Ruβischen Sprache”, 1731 (“The first bases of the Russian language”)), but he actually taught Russian for the future Empress Catherine II (Catherine the Great) being his most famous student. Adodurov’s work, recently republished, is widely available. For linguists this work is of interest – first of all as a scientific codification of the Russian language dating back to the first thirty years of the 18th century. However, the scientific novelty of this article consists in the evaluation of Adodurov’s work as a tutorial for teaching Russian as a foreign language, as per its original intent, and the description of Adodurov’s methods of teaching Russian according to the educational traditions in the middle of the 18th century. The author of the article concludes that Adodurov’s work is of great value as an early written Russian language grammar, but at the same time it is not worked out well enough to be a tutorial and the results of Adodurov’s teaching the Empress indirectly testify to this fact.

Dinámica de la conflictividad laboral desde experiencias obreras. La construcción de solidaridades en metalúrgicos bahienses de los años ´70
Authors: Zapata Ana Belén
Published: May 2023

En este trabajo nos proponemos analizar algunos aspectos que caracterizaron la dinámica de la conflictividad laboral en los años ´70 dentro de una de las metalúrgicas más importante de la ciudad de Bahía Blanca ubicada en la provincia de Buenos Aires en Argentina, la metalúrgica Bertrán Hnos. Nos centraremos en la reconstrucción histórica de algunos puntos específicos que hicieron a la dinámica de la acción colectiva de los trabajadores en esta empresa. Y específicamente analizaremos cómo procesos de conflictividad vividos por este colectivo obrero dejaron marcas subjetivas que operaron en la construcción de sus formas de solidaridad. Consideramos que las formas de organización dentro del espacio asambleario de los congresos de delegados resultaron fundamentales para pensar la construcción de solidaridades obreras que no existieron a priori ni emergieron de manera «natural» en el marco del proceso de lucha, sino que fueron construidas en el fragor de la misma.

Partiendo de la premisa de que la educación formal tiene una influencia directa en la construcción de cierto tipo de ciudadanía –en la producción y reproducción de imaginarios sociales y prácticas individuales y colectivas que tienen un impacto directo tanto en el medioambiente como en la sociedad y en la cultura– y siendo conscientes de la crisis ecológica global a la que nos enfrentamos actualmente, es necesario un cambio del sistema educativo para abordar las consecuencias medioambientales y sociales que genera el sistema capitalista neoliberal y patriarcal en el que nos encontramos. Siempre manteniendo una perspectiva de género e inclusiva que luche contra las opresiones de los poderes dominantes y fomente la equidad y la justicia social. Bajo esta idea, el presente artículo pretende analizar la Ley para la Implementación de la Educación Ambiental Integral en la República Argentina, que entró en vigor en junio de 2021, y reflexionar sobre su impacto en la sociedad desde una perspectiva ecofeminista.

Authors: Talukder Md.Ishtiaq Ahmed
Published: May 2023

Bangladesh’s ages old Bengali culture and heritage started from its language. Bangladesh has appeared as an independent country not long ago. It had to pay millions of lives within short period of time for its independence from Pakistan. This study will try to focus on the root cause which had affected the public perceptions and mobilise them towards war and defined their cultural identity. This article also discusses culture, cultural and political identity and their relationship in changing political thought and lastly the development of Bengali cultural identity into a political one in Muslim majority Bangladesh.
İki Dünya Arasında Sıkışmak: Roma Katolik Kilisesi’nde Eşcinsellik Dilemması
Authors: METE Duygu , TURAN Süleyman
Published: May 2023

Bu çalışma, Roma Katolik Kilisesi’nin eşcinselliğe ve eşcinsel birlikteliklere bakışını konu edinmektedir. Bu bağlamda çalışmada Kutsal Kitap literatürü, Kilise babalarının görüşleri, yayımlanan bildiriler ve papaların söylemlerinden hareketle Kilise’nin eşcinselliğe ilişkin öğretilerinin tarihsel gelişimi incelenmektedir. Nitekim yirminci yüzyılın ikinci yarısından itibaren toplumsal cinsiyet eşitsizliği, cinsel yönelim ve cinsel tercih özgürlüğü söylemleri ile küresel çapta büyük bir ivmeye sahip olan LGBTQIA+ hareketi, Kilise için de önemli bir endişe meselesi haline gelmiştir. Konu hakkında ilan ettiği belgelerde Roma Curia, eşcinsel eylemlerin doğa yasasına ve iffete aykırı bir günah olduğu yönündeki sürekli öğretisini devam ettirmiştir. Kilise içinden gelen tepkiler açısından bakıldığında ise Magisterium’un bu konudaki öğretileri, gelenekçi Katolik teologlar cephesinde kabul görürken bazı revizyonist teologlar tarafından ise tepkiyle karşılanarak eleştirilmiştir. Bu iki grup arasında kalan teologlar ise konuya ilişkin Kilise öğretilerini kabul etmekle birlikte eşcinsellere pastoral yardımda bulunulması gerektiğini savunmaktadır. Eşcinsellere yönelik nispeten ılımlı bir söyleme sahip olan Papa Francis’in de takip ettiği bu yaklaşım, Kilise ile eşcinsel Katolikler arasında bir köprü kurularak onlara merhametle eşlik edilmesini gerektirmektedir.

Percolation Model for Universal Scaling of Vegetation Net Primary Productivity with Climate Variables
Authors: Hunt Allen , Sahimi Muhammad , Ghanbarian Behzad , Poveda German
Published: May 2023

We show that a quantitative, physically-based model of water balance, combined with a model for the dependence of net primary productivity (NPP) of vegetation on evapotranspiration E leads to the universal scaling of NPP with the climate variables, namely, precipitation P and potential evapotranspiration Ep. The model for NPP is based on percolation theory. The water balance is derived based on the hypothesis that ecosystem selection is driven by optimizing NPP with respect to the principal hydrologic fluxes i.e., E and Q (=P −E; known as run-off), with the flux dependence of E being applied self-consistently to the NPP’s model. The predictions are compared separately with Budyko’s compilation of the NPP data as a function of Ep and P using the aridity index, AI = Ep/P, and Ep for each set of experimental data, and are shown to be in excellent agreement with the data.
Assessing Theories of State and Trait Change in Neuroticism and Symptom Improvement in the Unified Protocol
Authors: Stumpp Nicole , Southward Matthew W. , Sauer-Zavala Shannon
Published: May 2023

Researchers have shown neuroticism decreases with treatment (Roberts et al., 2017), although it is unclear if this reflects fleeting state-level changes (state-artifact position) or trait-level change (cause-correction hypothesis). These theories further propose that changes in neuroticism predict symptom change (cause-correction hypothesis) or are predicted by symptom change (state-artifact position). We compared these theories in a clinical trial of the Unified Protocol (UP). Participants (N = 38; Mage = 34.55, 71.1% female, 78.9% Caucasian) meeting DSM-5 criteria for a primary emotional disorder completed up to 12 weekly sessions of the UP. Neuroticism exhibited state-level changes by session 6 but trait-level changes by session 12. Within-person reductions in neuroticism exhibited bidirectional relations with anxiety symptom change but predicted unidirectional session-to-session reductions in depression. These findings provide relatively more nuanced support for the cause-correction hypothesis that the UP leads to trait changes in neuroticism that tend to precede symptom change.
The UnCODE system: A neurocentric systems approach for classifying the goals and methods of Cognitive Warfare

Cognitive Warfare takes advantage of novel developments in technology and science to influence how target populations think and act. Establishing adequate defense against Cognitive Warfare requires examination of modus operandi to understand this emerging action space. This includes the goals and methods that can be realized through science and technology. Recent literature suggests that both human and nonhuman cognition should be considered as targets of Cognitive Warfare. There are currently no frameworks allowing for a unified way of conceptualizing short-term and long-term Cognitive Warfare goals and attack methods that are domain- and species-agnostic. There is a need for a framework developed through a bottom-up approach that is informed by neuroscientific principles to capture relevant aspects of cognition. The framework should be at a level of complexity that is actionable to decision-makers in war. In this paper, we attempt to cover the existing gap by proposing the Unplug, Corrupt, disOrganize, Diagnose, Enhance (UnCODE) system for classifying the goals and methods of Cognitive Warfare. The system is neurocentric by conceptualizing Cognitive Warfare goals from the perspective of how adversarial methods relate to neural information processing in an individual or society. The UnCODE system identifies five main classes of goals: 1) Eliminating a target’s ability to produce outputs, 2) degrading a target’s capacity to process inputs and produce outputs, 3) biasing a target’s input-output activity, 4) monitoring and understanding the input-output relationships in targets, and 5) enhancing a target’s capacity and ability to process inputs and produce outputs. Methods can be divided in two categories based on access to the target’s neural system: direct access and indirect access. The UnCODE system is domain- and species-agnostic and allows for interdisciplinary commensurability when communicating attack paths across domains. In sum, the UnCODE system is a unifying framework that captures that multiple methods can be used to reach the same Cognitive Warfare goals.

Successful acquisition of handwriting skills as a child can have important consequences for later education. Possible graphomotor or handwriting disabilities (GD and HD, respectively) could reduce quality of life but effective remediation depends on proper diagnosis. However, current approaches to diagnosis and assessment of GD and HD have several limitations and knowledge gaps, e.g. they are subjective, they do not facilitate identification of specific manifestations, etc. The aim of this work is to address the limitations of current approaches and introduce a new scale (GHDRS - Graphomotor and Handwriting Disabilities Rating Scale) that will enable experts to perform objective and complex computer-aided diagnosis and assessment of GD and HD. The scale supports quantification of 17 manifestations associated with the process/product of drawing/handwriting. In addition, we provide normative data for Czech children attending up to the fourth grade of a primary school. Finally, the whole methodology of GHDRS design is made maximally transparent so that it could be adapted for other languages.

Background: Transitive inference has a long history of study in developmental contexts. However, trial-and-error transitive inference learning (in which participants infer item relations, rather than evaluate them explicitly from verbal descriptions) has been the subject of minimal study in childhood samples with reported clinical diagnoses.Methods: Children aged 8 to 10 underwent a battery of clinical assessments and received a range of diagnoses, potentially including autism spectrum disorder (ASD), attention-deficit hyperactive disorder (ADHD), anxiety disorders (AD), specific learning disorders (SLD), and/or communication disorders (CD). Participants also performed a simple trial-and-error learning task that tested for transitive inference. Response accuracy and reaction time were assessed in a statistical model that controlled for diagnostic comorbidity at the group level.Results: Participants in all diagnostic categories showed evidence of transitive inference, and thus succeeded at the task. However, a model comparison analysis suggested that those diagnosed with ASD succeeded in a qualitatively different way, responding more slowly to each choice and improving faster across trials than their non-ASD counterparts. Additionally, transitive inference performance was not associated with IQ. Overall, our data suggest that superficially similar performance levels between ASD and non-ASD participants may have resulted from a difference in the speed-accuracy tradeoff made by each group.Conclusions: This provides a preliminary profile of the impact of various clinical diagnoses on TI performance in young children. Of these, an ASD diagnosis resulted in the largest difference in task strategy.
Pneumatological Ecclesiology and Same-sex Marriage: A Non-essentialist Approach Using the Work of Eugene Rogers and John Zizioulas
Authors: Eagle David
Published: May 2023

The debate surrounding the morality of homosexual marriage is one of the most charged and fractious in the church today. As local congregations, national denominations, and international affiliations of Christians wrestle with this issue, significant conflict and division has arisen and continues to rage. At the center of this debate are so-called “arguments from creation,” that is, arguments that look to the natural or revealed “order of things” to discern God’s design for appropriate sexual behavior. This mode of theological argumentation has a long history in the tradition of natural theology, which assumes that divine direction (and even divine speech) is inherent in creaturely capacities. In this article, I will demonstrate that New Testament scholarship is agreed that in Romans 1:18-32 (the key NT text on the issue), Paul is not making an argument per se against homosexuality. Instead, this passage fits within the larger claim that he is trying to make throughout the book of Romans about Jew-Gentile relations. What Paul condemns here is the human propensity to judge others based on supposedly intrinsic qualities. He is using a stereotypical Jewish understanding of Gentiles, and turning it back against those who would argue for some special innate characteristic within Jews that makes them special and within Gentiles that makes them depraved.
