Authors: Gedje Dima Alfin Saputra , Lalus Herry Fridolin , Fakhruddin Fakhruddin
Published: July 2024

Telah dilakukan analisis review untuk menentukan nilai rata-rata operator gaya partikel pada potensial step satu dimensi dalam tinjauan persamaan Schrödinger, Persamaan Klein-Fock-Gordon dan persamaan Dirac. Review ini dimaksudkan untuk memberikan penjelasan secara terperinci dan mudah dipahami. Menentukan operator gaya pada kasus ini digunakan teorema Ehrenfest yang akan dianalisis untuk mencari nilai rata-rata operator gaya itu sendiri dengan menggunakan formula nilai rata-rata suatu operator. Hasil yang diperoleh dari review, memberikan bahwa nilai rata-rata operator gaya memiliki hubungan dengan kerapatan probabilitas dari masing-masing kasus dengan kajian masing-masing persamaan gelombang. Nilai rata-rata operator gaya untuk kasus ini dalam kajian persamaan Schrödinger dan Persamaan Dirac memberikan hasil yang mirip, dikarenakan kerapatan probabilitas masing-masing persamaan gelombang adalah fungsi yang kontinu pada titik batas. Berbeda dengan kasus yang sama dengan kajian persamaan Klein-Fock-Gordon diperoleh bahwa nilai rata-rata operator gaya tidak dapat digunakan formula umum nilai rata-rata, karena kerapatan probabilitasnya merupakan fungsi yang diskontinu. Sehingga diberikan solusi menggunakan persamaan Fescbach-Villars untuk menentukan operator gaya pada kasus ini dalam tinjauan persamaan Klein-Fock-Gordon.

This research aims to develop an automated diagnostic system for classifying lung diseases in X-ray images based on feature extraction using the Gray Level Co-occurrence Matrix (GLCM) with a Backpropagation Artificial Neural Network employing a Python GUI. In this study, 200 lung image data were utilized, divided into four classes with 50 data points each. The four categories of image classes are normal lungs, Pneumonia, Tuberculosis, and Covid-19. The training and testing data were split in a 92:8 ratio, resulting in 184 training data and 16 testing data. The parameters include four input layers, eight hidden layers, two output layers, alpha 0.8, 2000 iteration, and target error = 0.0001. Then, it continued with feature extraction using the GLCM to obtain texture characteristics in lung images. In the training stage, the best results were obtained in iteration 2000 with a Mean Squared Error of 0.005% and a calculated time of 167.319 seconds. At the testing stage, a reasonably high accuracy was obtained, 93.75%, with a calculated time of 0.014 seconds. This result indicates that the method can prove lung images.

Published: July 2024

Abstract: This study aims to solve research questions on whether support for zakat institutions (ZIs) from regional governments in the East Java province of Indonesia affects the social and economic conditions of the region. The authors observed 11 samples of cities and districts in East Java over the last three years (2019 to 2021). Thirty-three research data were processed using panel data regression techniques with a fixed-effects model approach. Data was obtained from the National Zakat Institution (Baznas). The results show that financial support from the local government budget (RREB) and through zakat regulations of the regional governments in East Java have a positive effect on GRDP and a significant negative effect on the Gini index. In addition, zakat distribution activities in East Java have also been shown to have a significant positive and negative effect on GRDP growth and the Gini index. This study also provides recommendations to the local government of East Java and zakat stakeholders in synergising to build a better regional ZI system to support the regional economy.

Abstract: The current study examines the barriers faced by marine product exporters in Andhra Pradesh, India. These are categorised into infrastructural, operational, human resource, financial, raw material, general, and exporting process barriers. The present study is descriptive in nature, and surveys 115 marine exporters from Andhra Pradesh. Cronbach’s alpha and factor analysis are used to assess the reliability of the questionnaires and indicate a good reliability score between the variables. Following that, we used a single-factor Analysis of Variance (ANOVA) test to determine the significance of the variables. Finally, the findings show that infrastructural, general, and exporting process barriers have a positive significant relationship with export performance, whereas human resource, financial, raw material and operational barriers have a negative significant relationship. This study can be beneficial to state and central governments by increasing foreign reserves and tax revenue, increasing employment opportunities, expanding the global market, properly utilising natural resources, and improving banks’ financial schemes.
Legitimate Trade: Catalysts for the Exploitation of the Akwanga Division in Northern Nigeria 1903-1960
Authors: Yusuf Dogara Ja'afaru , Abdullahi Hashimu
Published: July 2024

Modern Africa emerged fragmented and ravaged after an era of European colonialism. The national economies of the emerging nation-states were grossly deformed and proved to be incapable of meaningful economic growth. Historical research has established that the introduction of taxation, the influx of foreign capital, the activities of marketing boards, and commissioned buying agents served as the vehicles for colonial exploitation. A full account of the triple catalyst for the colonial exploitation of the economy and population of the Akwanga division in northern Nigeria has yet to be jointly examined. This study aims to examine the circumstances that precipitated the exploitation of this area during the colonial period. Attention is given to the colonial conquest and the level of resistance offered by the people of northern Nigeria, in particular the Akwanga division. Emphasis is also given to cash crop production as a cause of economic stagnation, besides examining the extent to which the transatlantic slave trade and the legitimate or free trade were responsible for the lack of development in the Akwanga division. We posit that colonial cash crop production solely benefited the European capitalists while damaging the local economy. The historical method is employed in this analysis, and both primary and secondary sources are consulted in order to achieve the aims and objectives of this work.
Isu dan Pola Kecenderungan Undi Wanita dalam Konteks Persaingan Politik UMNO dan DAP di Johor, PRU 12 hingga PRU 14 Issues and Patterns of Women's Vote in the Context of UMNO and DAP Political Competition in Johor, GE 12 to GE 14

Published: July 2024

The role of women in politics is not only a complement to the democratic system of practice, but it plays an important role in determining the viability of their respective political parties in the context of competition to strengthen their position. This study discusses the political competition between DAP and UMNO in Johor in the context of femininity, i.e. the details of the candidates at stake by both parties as well as the issues brought up by female candidates during the campaign. The competition of female candidates from these two parties is determined by two main factors, which are the candidates that the parties stake and the issues that are brought up during the campaign period. These two factors further affect the political survival of these two parties in the context of competition in Johor. In addition, women's voters also play an important role as political determinants in Johor. The dominance of these female voters allowed each party to determine the political viability of Johor as the number of female voters increased. Nowadays, every political party in Johor tries to show their women to to gain more support from women’s voters. In addition, this article discusses the tendency of votes from women in Johor based on primary data from the Malaysian Election Commission. Therefore, this study found that the role of the female candidates who are staked by these two parties is one of the important factors in determining the political survival of their respective parties in Johor based on the selection of female candidates who are competing and the issues brought by the female candidates in the election campaign period in this state.
The Thai Malay Muslim Exodus of 1981: A Malaysian Dilemma
Authors: A Rahimin Dunita Nabila , Tze Ken Danny Wong
Published: July 2024

In 1981, the Malaysian government was flabbergasted by the presence of Thai Malay Muslim refugees in the northern part of Peninsular Malaysia. The presence of Thai Malay Muslim refugees was regarded by the Malaysian government as Thai internal affairs, with Malaysia preferring to stay out of the fray. However, the growing number of Thai Muslim refugees, combined with Muslim separatist issue and active red insurgents on the Malaysia-Thailand border, had put the Malaysian government under strain. With its low-key involvement, the Malaysian government began to deal with the issue thoroughly on humanitarian grounds. This study investigates the causes of the Thai Malay Muslim Exodus, the Malaysian government’s struggles in dealing with the issue, and the extent to which the Thai Malay Muslim Exodus affected Malaysia-Thailand relations. This study uses qualitative research to analyse the event in chronological order by referring to newspapers. Authoritative secondary sources, such as theses, books, and journal articles were also used in this study. Since the existing literature on the Thai Malay Muslim Exodus is very limited, the study is expected to fill a gap in the Thai Malay Muslim literature. This study discovers that, the Malaysian government was willing to help the refugees as they are of Islamic faith. Despite the burdening situation of dealing with the refugees, the Malaysian government strived to maintain a cordial relationship with the Thai government who was cooperating with them in suppressing the Communist insurgents at Malaysia-Thailand frontier.
Strategi Perjuangan Parti Malaysian Chinese Association (MCA) dalam Masyarakat Cina, 1958-1969 The Struggle Strategy of the Malaysian Chinese Association (MCA) in the Chinese Community, 1958-1969

Published: July 2024

Makalah ini akan memperinci strategi perjuangan parti Malaysian Chinese Association (MCA) dalam menangani isu-isu yang dihadapi oleh komuniti Cina selepas Tanah Melayu mencapai kemerdekaan sehingga ambang tragedi 13 Mei 1969. Pada tempoh ini, MCA berhadapan dengan isu pendidikan Cina, bahasa kebangsaan, penubuhan Malaysia dan Universiti Merdeka. Tiga pemimpin MCA iaitu Lim Chong Eu, Cheah Toon Look dan Tan Siew Sin yang menerajui MCA pada tempoh masa ini menggunakan strategi tersendiri untuk menyelesaikan masalah yang dihadapi oleh komuniti Cina. Penulisan ini menggunakan pendekatan kualitatif, iaitu kaedah perpustakaan dengan merujuk sumber primer seperti minit mesyuarat parti, laporan tahunan parti, perlembagaan parti, Surat Persendirian H.S. Lee, Surat Persendirian Tan Cheng Lock, rekod Pejabat Tanah Jajahan, surat-menyurat parti serta akhbar, dan sumber sekunder seperti buku dan artikel jurnal. Penulisan ini mendapati bahawa strategi perjuangan MCA adalah berdasarkan objektif MCA seperti termaktub dalam Perlembagaan MCA yang mengutamakan keharmonian antara kaum serta menjaga kepentingan masyarakat Cina. Justeru, strategi perjuangan MCA dalam masyarakat Cina perlu mengimbangkan tuntutan masyarakat Cina dan pendirian parti United Malays National Organization (UMNO). Keadaan ini dapat dilihat dengan jelas melalui strategi perjuangan MCA dalam isu pendidikan Cina daripada tahun 1958 sehingga 1969. Justeru, strategi perjuangan MCA cuma dapat berkompromi dalam memenuhi sebahagian tuntutan masyarakat Cina terutama golongan pendidikan Cina yang dapat diterima oleh UMNO dan bukan sepenuhnya. Peranan strategi perjuangan MCA ini amat penting dalam konteks menstabilkan politik negara dengan mengelakkan konflik antara kaum.

Published: July 2024

Fertilization of cacao seedlings is not yet a widely accepted practice in the Philippines and research studies are needed to define sources, rates and timing of application. The use of fertilizer as an agricultural technique for supplying the nutrients necessary for the development of cacao seedling in the nursery is an option. The objective of this study was to determine how different doses of the fertilizer can affect the growth of cacao seedlings in terms of days of emergence, plant height, stem girth, and number of leaves. The study was conducted at Buhangin Baler in Aurora province, the Philippines from June 2022 to December 2022. The experiment used a randomized complete block design with three treatments and four replications. The treatments were: T1 – Control (No inorganic fertilizer); T2 – Recommended Rate of Inorganic Fertilizer (RRIF) based on soil analysis result; and T3 – Double the Recommended Rate of Inorganic Fertilizer based on soil analysis result. The variant T2 or Recommended Rate of Inorganic Fertilizer applied had the best response out of the three treatments in terms of plant height, and stem girth and has a high percentage of survival after grafting and fertilization. The results showed that the grafted seedlings (BR 25 cacao variety as rootstock and Criollo cacao variety as scion) responded well in terms of plant height, and stem girth and has a high number of survival rate (60-65%) after grafting and application of 25% and 50% fertilizer. In terms of number of leaves, the grafted BR 25 cacao variety as rootstock and Criollo cacao variety as scion and grafted BR 25 cacao variety as rootstock and UF 18 cacao variety as scion were best performing at both single (T2) and double (T3) rate of fertilizers applied. Keywords: cacao seedlings, Recommended Rate of Inorganic Fertilizer, rootstock, scion
Dynamics of alcoholic fermentation and the quality of white organic wines produced with selected yeasts
Authors: Georgiev Stefan ,   University of Plovdiv “Paisii Hilendarski”, Bulgaria
Published: July 2024

The dynamics, duration and specificity of alcoholic fermentation are among the factors determining the quality of white wines. These features depend mostly on technological parameters such as temperature (16°C, 20°C) and amount of total sugars (180 g/dm³, 220 g/dm³). The aim of the current study was to assess the fermentation activity of yeast Saccharomyces cerevisiae from EXCELLENCE® line, intended for production of wines under Organic and National Organic Program (NOP) standards. The used yeasts have a high fermentation activity and are characterized with relatively fast alcoholic fermentation. The result showed that there was no difference in the dynamics of alcoholic fermentation of yeast strains from the used lines. The quick fermentation of sugars was observed in the initial (lag phase) and in the final stage (silent fermentation). However, the experimental variants with different sugar contents completed the process at the same time. A straightforward relationship between the fermentation of sugars and the changes in pH was not observed. According to the mass of the obtained yeast lees, there was a clear difference between all experimental variants. Nevertheless, the mass of the obtained yeast lees for all variants was lower than the normatively allowed. Keywords: yeast, alcoholic fermentation, dynamics, sugars, relative density, pH

Published: July 2024

The oil-bearing rose (Rosa damascena Miller) is the most important essential oil crop in Bulgaria. In May 2023 in rose plantations located in the region of Zelenikovo village the rose soft scale Rhodococcus perornatus (Hemiptera: Coccidae) was found in high density of 5% infested rose bushes (Cockerell & Parrott, 1899). The rose plantations are growing within the conventional farming. Two chemical (Closer – 0.02%, 0.04% and Sivanto prime – 0.05%, 0.1%) and one biological (Naturalis – 0.1%, 0.2%) insecticides were tested against the rose soft scale. All tested products showed better results in higher concentrations. Closer indicated the fastest initial action. In the concentration of 0.04% on the 1stday after the treatment its efficacy was 100%. Sivanto prime in the concentration of 0.1% on the 5th day after the treatment showed an efficacy of 100%. The biological insecticide Naturalis had a slower action and in the concentration of 0.2% on the 7th day after the treatment its efficacy was 90%.

Structure, electrical and optical properties of ZnO and Cu-doped ZnO films prepared by magnetron sputtering at different H2 fluxes
Authors: Zhu Bailin , Cai Xiaojian , Xie Ming , Shi Xinwei
Published: July 2024

Zn1-xCuxO (x = 0 and 0.02) films were prepared by RF magnetron sputtering in
H2-containing atmosphere at 150 ?C. Their structure and optical-electrical
properties as functions of H2 flux were investigated. With increase of H2
flux, thickness of both films decreases and their surface roughness
increases at first and then decreases. Preferred (002) orientation and
improved crystallinity of both films were observed in specific interval of
H2 fluxes. With increasing H2 flux, the VO content of ZnO and Cu-doped ZnO
films decreases at first and then increases and decreases, respectively, but
the Zni content in both films increases at first and then decreases.
Compared with ZnO films, Cu-doped ZnO films have lower VO and Zni contents,
and they maintain thicker film thickness and higher crystallinity at
largerH2 fluxes. Both films can obtain low resistivity in appropriateH2 flux
ranges, but their resistivity increases significantly after vacuum
annealing. With increasing H2 flux, intensity ratio of A1(LO) to E2 high
scattering peaks, I(A1(LO))/I(E2 high), tends to increase, and scattering
peaks around 135 and 185 cm?1 appear. Compared with ZnO films, Cu-doped ZnO
films can obtain lower resistivity, better electrically conductive stability
in air, lower I(A1(LO))/I(E2 high) and smaller Eg. High H2 fluxes can cause
decrease of TVis of the Cu-doped ZnO films. The influence mechanisms of
introducing H2 on microstructure and lattice defects of the films were
discussed, and correlation between the optical-electrical properties of the
films and the microstructure and lattice defects was analysed.
Preparation and properties of Eu3+ doped tungstate red phosphor powders
Authors: Wang Yaping , Liu Anqin , Li Zhijuan , Wang Zhuo , Chen Yunxia
Published: July 2024

NaY(WO4)2:Eu3+ phosphors were synthesized using high-temperature solid state
method. The effects of Eu3+ doping concentrations on structure and
photoluminescence properties of the powders were investigated. The results
indicate that the pure NaY(WO4)2:Eu3+ phase can be produced by calcining at
800?C where Eu3+ doping does not alter the main phase structure. Eu3+ ions
were successfully incorporated into the crystal lattice, replacing Y3+ at
the B-site. This caused gradual shifts of the characteristic X-ray
diffraction peaks to lower 2? angles. Morphological characterization
revealed that the sample particles had irregular polygonal shapes with sizes
ranging from 100 to 300 nm. There was minimal variation in morphology among
samples with different doping concentrations. The samples exhibited the
characteristic spectral emission of Eu3+ and emitted red light at a
wavelength of 616 nm when excited by 394 nm near-ultraviolet light. The
luminescence intensity of the nanophosphor gradually increased with
increasing Eu3+ doping concentration, reaching its maximum at a doping ratio
of 0.6, followed by a decrease due to the concentration quenching. The
quenching mechanism was analysed to be primarily dipole-dipole interaction,
in accordance with the Dexter?s theory of doping concentration. The
luminescence positions of the phosphors slightly changed with varying Eu3+
doping concentrations, and the colour coordinates closely matched the
standard value of the red colour in the National Television Standards
Committee, confirming the stability of the obtained powders as red
phosphors.
Electrical properties and electromagnetic radiation characteristics of cement/Ba0.06Bi0.47Na0.47TiO3 composites
Authors: Kumar Amit , Subrato S , Prasad Kamal
Published: July 2024

The study examined the emission of electromagnetic radiation (EMR) from
cement/Ba0.06Bi0.47Na0.47TiO3 (BBNT) composites when subjected to drop
weight impact loads, aiming to explore their potential as sensors in civil
structures. The generation of EMR in this context can be attributed to the
increased movement of ions within pores and dipole oscillation along the
grain boundaries of BBNT. The increase of BBNT content and impact load cause
a noticeable rise in the values of EMR voltage, dominant frequency and the
average rate of EMR energy release. Notably, the impact-generated EMR
voltage data can be excellently fitted with a 5th-order bivariate polynomial
function (adjusted r2 = 0.9353). Furthermore, the EMR voltage exhibits a
decreasing pattern when measured at various distances from the sample, until
it stabilizes after 12 cm. These findings suggest that the EMR technique
holds promise as an effective tool for real-time monitoring of civil
structures in situ.
Synthesis of TiB2 powders by borothermal and carbothermal reduction of TiO2
Authors: Abdelgawad Mohamed Mahrous , Biçer Hülya
Published: July 2024

Titanium diboride powders were synthesized from TiO2 following different
reduction methods at temperatures range from 1000 to 1400?C for 1h under
flowing argon gas. The reduction processes used in this study are classified
as TiO2 + B (borothermal reduction), TiO2 + H3BO3 + C (carbothermal
reduction) and TiO2 + B + C (combined reduction). XRD peaks of TiO2 phase
are present for each sample below 1100?C. It was also observed that XRD
peaks of TiO2 disappeared and TiB2 was formed in borothermal and combined
reduction methods at temperature of 1100?C and above. In the carbothermal
method, TiBO3 and TiC phases were present at these temperatures and TiB2
could only be obtained after heat treatment at 1400?C. However, this
temperature also caused considerable particle growth and formation of the
powders with hexagonal shape morphology. The powders synthesized by the
carbon-containing reduction process contained residual carbon.
Conceptualizing invisible housework in sociological research: Cognitive, mental or emotional labor
Authors: Barada Valerija , Cop Blanka , Racic Jasna
Published: July 2024

This article discusses the possibility of improved conceptualization and
operationalization of cognitive, mental, and/or emotional labour as a form
of housework. Since it falls into the domain of so-called invisible work,
which implies the performance of several tasks at the same time,
fragmentation of time and scattered activities, the research so far has
largely neglected to survey this type of work, thus leaving unrecorded the
real amount of work that mostly women perform in unpaid and invisible work
in the family and household. To put an end to such neglect, this article
proposes the introduction of the concept of cognitive and emotional
household management (KEUK) and defines the dimensions for its
operationalization: management of resources and time (cognitive work) and
management of relationships and emotions (emotional work). These dimensions
are studied through interpersonal relationships within the household, then
with the relatives and with the wider community, and finally in relation to
other institutions. The intensity of these activities is also
operationalized, considering whether they are performed daily or
occasionally. The article also lists 14 items with which these dimensions
were investigated in a survey questionnaire. The authors of the article
believe that with this kind of conceptualization and operationalization,
they have contributed to a clearer definition and application of this
concept in the broader research of housework, the relation of work and
family obligations, and the study of gender relations and roles.
Contemporary journalism: Profession or a “bullshit job”
Authors: Popovic Helena , Hromadzic Hajrudin
Published: July 2024

The aim of the paper is to rethink the position of the journalistic
profession in the contemporary social contexts of the 21st century, within
the context of social changes determined by capitalism in its radical stage,
and the permanent transformations of digital technologies as the main tool
for production and consumption. The central question that arises is whether
we can still think of journalism as a profession in accordance with the
principles formed in the midtwentieth century, or whether the journalistic
profession is ?dead?, transformed into a ?bullshit job?? If we look at the
three main indicators of professional journalism: public interest and the
watchdog function; autonomy; and the adherence to specific professional
norms; it seems, by looking at actual journalistic practices, that all three
indicators that fundamentally legitimize journalism as a profession has
eroded significantly. The main claim is that journalism, to a large extent,
has turned into a ?bullshit job?, even if the ?old? normative principles of
the profession still serves to legitimize it, but with no stronghold in real
journalist practices. Of course, this does not mean that professional
journalism, defined according to the principles established in mid-twentieth
century, is not still relevant, even crucial for the public and public
interest. This is why, in the conclusion of the paper, we plead for the
strengthening of those media organizations that nurture the protection of
the public interest as well as investigative and critically oriented,
independent journalism.

Published: July 2024

La dislexia es una dificultad específica del aprendizaje que afecta la lectura y la escritura sin estar asociada a una discapacidad intelectual general. La investigación destaca que la identificación temprana es crucial para implementar intervenciones adecuadas que permitan a los estudiantes alcanzar su máximo potencial académico. El método de investigación utilizado es un análisis bibliográfico y documental, revisando literatura académica, informes de investigación y políticas educativas recientes. Los principales hallazgos indican que la dislexia se manifiesta a través de dificultades para reconocer palabras familiares, problemas con la ortografía y lectura lenta, lo que presenta un desafío para los educadores. Para abordar estas dificultades, se recomienda un enfoque integral que combine observaciones, evaluaciones formales e informales y la colaboración con especialistas y familias. La colaboración entre docentes, psicopedagogos y padres es esencial para desarrollar planes de intervención personalizados. Además, crear un entorno inclusivo y de apoyo en el aula es fundamental para el éxito académico y emocional de los estudiantes con dislexia. El artículo concluye que un enfoque multifacético y colaborativo no solo facilita la identificación temprana, sino que también asegura que los estudiantes reciban el apoyo necesario para superar sus dificultades y desarrollarse plenamente en el ámbito educativo.
Caribbean Bodies of Global Desire: Tourism and Eroticism in Contemporary Cinema
Authors: Planas Justo
Published: July 2024

Tourism is a crucial economic sector in many Caribbean nations and the primary channel for direct interaction between the local population and visitors from around the world. Although not typically recognized in official statistics, Caribbean bodies effectively transform into a tourist attraction that supports the livelihoods of low-income families and makes a significant contribution to the domestic economy of the islands. Through an analysis of films set in the Dominican Republic, Haiti, and Cuba, this article debates the intricate connections between pleasure economies, traditional gender roles, and familial structures, while it challenges the prevailing victim-victimizer narrative and provides a multifaceted perspective on sex tourism. Access by first-world tourists to international mobility and foreign currency creates a power imbalance in their interactions with Caribbean individuals. This imbalance worsens existing disparities related to gender, race, and age. In this context, Holy Beasts (La fiera y la fiesta, 2019) is examined as a notable example, satirically deconstructing conventional narratives of erotic commodification in the Caribbean.
El turismo es un sector económico crítico en muchas naciones del Caribe y el principal canal de interacción directa entre la población local y los visitantes de todo el mundo. Aunque no suelen ser reconocidos en las estadísticas oficiales, los cuerpos caribeños se transforman efectivamente en una atracción turística que apoya el sustento de las familias de bajos ingresos y hace una contribución significativa a la economía nacional de las islas. A través de un análisis de películas ambientadas en la República Dominicana, Haití y Cuba, este artículo expone las intrincadas conexiones entre las economías del placer, los roles tradicionales de género y las estructuras familiares, a la vez que desafía la narrativa predominante de víctima-victimario y proporciona una perspectiva multifacética sobre el turismo sexual. El acceso de los turistas del primer mundo a la movilidad internacional y a las divisas internacionales crea un desequilibrio de poder en sus interacciones con los individuos del Caribe. Este desequilibrio empeora las disparidades existentes relacionadas con el género, la raza y la edad. En este contexto,  La fiera y la fiesta (2019) se examina como un ejemplo notable que deconstruye satíricamente las narrativas convencionales de mercantilización erótica en el Caribe.
Perspectivas de análisis sobre los procesos políticos de reelección presidencial y la democracia en Centroamérica.
Authors: Achoy Sánchez José Mario , Cambronero Torres Andrei
Published: July 2024

Resumen
El artículo aborda el vínculo y las realidades sobre la reelección presidencial y la calidad de la democracia, en los sistemas políticos de Centroamérica. Para ello, se emplea un marco referencial que se apoya en el desarrollo normativo-constitucional de la flexibilización a la reelección presidencial en esta región, así como los principales pronunciamientos jurisprudenciales que al efecto han señalado los tribunales constitucionales de estas naciones. Con un enfoque metodológico mixto, se acude al análisis cualitativo para visibilizar los ajustes constitucionales de la reelección; mientras que, desde una perspectiva cuantitativa, se estudia el vínculo entre la continuidad del mandato presidencial y los principales indicadores de la calidad de la democracia. Los hallazgos muestran un desarrollo divergente en cada uno de los países sobre la flexibilización de las cláusulas que permiten la reelección presidencial; por su parte, los datos también muestran que no puede darse un tratamiento generalizado sin tomar en cuenta aspectos como la consecutividad de la reelección y los factores políticos contextuales que inciden sobre la calidad de la democracia en los sistemas políticos bajo estudio.

En este artículo analizo cómo la novela Esta herida llena de peces (2021) de la escritora colombiana Lorena Salazar Masso nos invita a repensar los lugares vulnerables y aislados asignados a dos prácticas cotidianas en contextos de violencia: la maternidad y el duelo. Propongo que la novela plantea la paradoja de la vulnerabilidad en personas afectadas por el conflicto armado colombiano , en especial en las víctimas de la Masacre de Bojayá que fue perpetrada por la guerrilla de las FARC en un enfrentamiento con los paramilitares en 2002 en la comunidad Bellavista, departamento del Chocó (Colombia). La paradoja se refiere a la vulnerabilidad como un estado de debilidad y parálisis que es susceptible al daño, pero también como potencial de transformación, el hecho de haber estado expuesto a ser herido despierta la responsabilidad por el cuidado del otro y la necesidad de acción para prevenir otra herida. Lo que me lleva a sugerir estos espacios vulnerables como espacios de resistencia desde prácticas que han sido ejercidas tradicionalmente por comunidades del Pacífico Colombiano, donde su reactivación y resignificación funciona como una alternativa para protegerse y rehusarse al control y destrucción total de la violencia. Ambas prácticas consideran lo vulnerable como potencia que subvierte la idea de cuidado unidireccional hacia el ser inerme y más bien se proponen como momentos de acompañamiento y cuidado reciproco que recomponen el tejido comunitario como estrategia para sobrevivir y re habituarse a ese espacio que ha sido destruido.

O objetivo deste artigo é o de investigar as estratégias literárias manejadas pelo escritor escocês Arthur Conan Doyle (1859-1930) para representar os eventos relacionados ao motim indiano de 1857. Desse modo, a partir da leitura da trama e dos elementos narrativos de O Signo dos Quatro (1890), visa-se se pensar os vínculos entre cultura e imperialismo na segunda aventura protagonizada por Sherlock Holmes.
Sobre quando decidi fazer Letras

Esta pesquisa investiga as trajetórias narrativas de quatro estudantes ingressantes do curso de Letras. Para isso, consideramos o conceito histórico-cultural de perezhivanie, referente às experiências emocionais que os sujeitos atravessam como parte de seu desenvolvimento, destacando a influência do contexto sociocultural refratada pelo sujeito. A vivência em questão teve como foco a escolha pelo curso, as primeiras memórias de aprendizagem de línguas, a inclinação para a docência/tradução e a tomada de decisão pelo curso. Os resultados sugerem uma relação afetiva com o campo da linguagem desde a infância e a presença de professores incentivadores. No entanto, desafios como a desvalorização da profissão e a falta de apoio social foram recorrentes. Além disso, a aprendizagem de uma nova língua figura afetivamente como uma válvula de escape. O estudo busca, desta forma, compreender quais fatores são determinantes na escolha pelo curso de Letras, contribuindo para melhor oferta desses cursos no ensino superior.

One strategy to increase peanut production is to use good-quality seeds. The content of the seed determines the quality of the seed. Drying with low relative humidity can lower the drying temperature so that drying is done quickly and seed quality is maintained. This research was conducted to analyze the process and differences in peanut seed drying using dehumidifier drying and oven drying methods. Drying was carried out using a dehumidifier and oven drying machine at 30 °C, 40 °C, and 50 °C until the moisture content reached 9%, with observations every 30 minutes. Then the dried seeds were analyzed for their physical and physiological qualities. The results showed that the time needed for dehumidifier drying was faster than oven drying, with the details of dehumidifier machine drying at 30 °C, 40 °C, and 50 °C being 18.5 hours, 15 hours, and 10.5 hours. While drying in the oven at the same temperature, it takes 21 h, 17 h, and 12 h. From the results of the analysis of the physical quality of the seeds, the germination test, and the vigor test, it can be seen that dehumidifier drying gave the highest seed percentage results of 98%, 98%, and 88%. Keywords: Dehumidifier, Drying, Peanuts, Seed Quality, Water content.

Our research focuses on understanding the disparity in risk perception when operating maritime autonomous surface ships (MASS) between onboard and through screens. In our initial step, we conducted experiments using a ship simulator, involving 4 students aspiring to be navigators. They navigated through screens and participated in debriefing sessions. Human gaze movement was utilized to ascertain the ability to comprehend navigational risks solely through observation. Simultaneously, salivary alpha-amylase samples were taken to verify their accurate risk cognition. The key finding indicates that human gaze movement aids in precisely understanding navigational risks, suggesting the feasibility of future ship operations through screens. Our research targets navigators crucial in global logistics, aiming to enhance safety in remote ship operations by demonstrating that risk cognition is achievable through human gaze movement. This breakthrough is vital for the evolving realm of MASS operations.
