Authors: Angelo Marly Aparecida Machado , Carvalho Sônia Marise Salles , Aranha Elzo Alves
Published: February 2024

O novo cenário social evidencia a necessidade de mudanças no ciclo de atuação profissional dos professores do ensino médio para promover o desenvolvimento de habilidades e competências empreendedoras. Contudo, existe uma lacuna na literatura que propõe programas de formação de professores que possibilitem conectar as práticas dos professores do ensino médio na perspectiva da educação para o empreendedorismo. Essa interface e conexão permite novos conhecimentos sobre o processo de ensino e aprendizagem e favorece a criação de um espaço favorável à inovação, além de conscientizar sobre o uso de ferramentas inovadoras nas práticas pedagógicas. O objetivo desta pesquisa é propor um percurso de formação de professores, bem fundamentado, que estabeleça conexões e interfaces no ciclo de prática profissional do educador no ensino médio. Portanto, esta pesquisa tem dois propósitos: 1) explorar o ensino no contexto do ciclo de prática profissional do professor e 2) propor a inovação por meio de ferramenta pedagógica que permita a prática da educação empreendedora. Como resultado, estabelece-se uma ligação entre o ciclo de prática do professor no ensino médio e a educação empreendedora. Os principais aspectos-chave inerentes a ambos os temas foram apoiados nos componentes do metamodelo de comportamento empreendedor de Filion (2003), ciclo de prática docente de Fink et al (2005), com a potencialização de habilidades e competências empreendedoras proposta pela ferramenta Entrepreneurial Dynamic Learning - EDLE (Aranha et al., 2005). O resultado dessa pesquisa mostrou que o uso da ferramenta EDLE possibilita uma prática pedagógica que agrega valor no ciclo da prática profissional do professor e ao mesmo tempo proporciona educação empreendedora capaz de potencializar as competências empreendedoras dos estudantes.
Condoreirismo de Castro Alves
Authors: Silva Amós Coêlho da
Published: February 2024

Castro Alves foi influenciado pelo poeta francês Victor Hugo. Esta influência denomina-se, do nome do poeta: hugoanismo, ou condoreirismo, não só devido à originalidade de Castro Alves, relativamente à ave símbolo da América do Sul nos Andes, mas também, à sua inspiração tão profunda quanto à altura do vôo do condor. Os dois poemas abaixo são de fôlego enciclopédico. Leremos os dois poemas mais emblemáticos do brado poético de Castro Alves contra a escravatura: “O Navio Negreiro” e “Vozes d’África”.
Concession contracts: analysis of the subsidiary liability of the public administration for labor debts
Authors: Rolim Mayara Rayssa da Silva , Dias Daniella Maria dos Santos , Velloso Filho Gabriel Napoleão
Published: February 2024

Management and concession contracts, of which public-private partnerships are a type, have become the most dynamic form of state action in the economy. Given the trends of today's capitalism and the official public policy announced, they should multiply, in line with the announced Growth Acceleration Program (PAC) 2023. It is expected that, in the event of default by employers, it will be inevitable to ask, in court, whether the state can be held jointly or severally liable for labor debts. Therefore, the aim of this article is to verify the extent to which public administration liability occurs in concession contracts. The methodology applied is based on the deductive method and the research is qualitative in nature, with the data source based on documentary, bibliographical and case law research. It should be noted that the majority of case law recognizes that the public administration is subsidiarily liable for the debts of so-called "management contracts", a reasoning that should be extended to the labor debts of concessionaires, including in public-private partnerships.

Parents’ Environmental Literacy: From Knowledge to Pro-Environmental Behavior
Authors: Masykuroh Khusniati , Yetti Elindra , Nurani Yuliani
Published: February 2024

Background: Environmental problems are still unsolved, so it is necessary to strengthen parents’ environmental literacy because they play an active role in modeling behavior for their children, including pro-environmental behavior and awareness.

 

Purpose: this study investigated parents’ environmental literacy in pro-environmental behavior, including consumption-related behavior (C-RB) and nature protection behavior (NTB), based on environmental knowledge, environmental affect, and environmental self-efficacy (ES-e).

 

Methodology: The research data collection was done by using a questionnaire in Likert scale format. The study participants were 275 parents. They have early childhood, which determines by accidental sampling from eight provinces in Indonesia. Data analysis begins with descriptive and correlational analysis and continues with structural equation modeling (SEM) analysis to test hypotheses and research models.

 

Results: This study found that pro-environmental behavior is influenced by environmental knowledge by mediating environmental affect and ES-e. Its path is that environmental knowledge affects environmental affect and ES-e and then has implications for pro-environmental behavior.

 

Practical implications: The significant direct and indirect effects were confirmed, therefore a new model of the effect of environmental knowledge on pro-environmental behavior mediated by environmental affect and ES-e was found. This model can explain the dynamics parents’ environmental literacy: from environmental knowledge to pro-environmental behavior through the mediating mechanism of environmental affect and ES-e. Therefore, practitioners, academics, and researchers can discuss, adapt, or adopt these findings to develop pro-environmental in the future.

Authors: TRUJILLO GONZÁLEZ JULIO , DE SEDAS ABRAHAM
Published: February 2024

Las series de tiempo son esenciales en diversos campos, permitiendo analizar patrones y predecir tendencias. El modelo ARIMA, aunque popular, asume estacionariedad, lo que puede no ser adecuado para series con patrones estacionales. Por ello, se introduce el modelo SARIMA, que considera la estacionalidad. El Aeropuerto Internacional de Tocumen en Panamá, un hub importante en América Latina, necesita predecir el flujo de pasajeros para su gestión eficiente. Este estudio adopta un enfoque no experimental y longitudinal para analizar y predecir el flujo de pasajeros utilizando SARIMA. A pesar de los desafíos de datos de 2020 y 2021 debido a la pandemia, el modelo proporcionó  predicciones precisas. La gestión aeroportuaria eficiente requiere prever tendencias futuras, y herramientas como SARIMA son valiosas en este contexto. Sin embargo, es crucial la selección adecuada de parámetros y validación. En el ámbito turístico, predecir tendencias y adaptarse a cambios es esencial para la sostenibilidad del sector.

Background: Currently, a topical area of research is the multidimensional approach to both reliable tools and professional interventions aimed at improving the attitudes of Ukrainian society toward people with disabilities in the context of the armed conflict in Ukraine. The aim of the study: The purpose of this study was to study the factor structure of the Multidimensional Attitudes Scale Toward Persons with Disabilities (MAS) questionnaire on a sample of Ukrainian students to create an adaptation of the original version (MAS-UA). Material and Methods: The main authors of the questionnaire gave their consent for the adaptation. The Ukrainian version of the MAS was developed using the method of back translation from the original language. The proposed multi-factor structure of the MAS-UA was tested in an anonymous online study of 1619 Ukrainian students.Results: The factor analysis and a parallel exploratory factor analysis resulted in a 5-factor structure for the MAS-UA (the classic domains – cognitive, affective, and behavioral – and two additional domains, negative effects and items concentrated in the factors “Calm” and “Desire to communicate”). These five factors yielded 62.6% of the total variance score. Conclusions: The MAS-UA was developed and presented as a reliable instrument for examining attitudes toward people with physical disabilities. The instrument can be used for the initial assessment when developing prevention and educational programs in the field of social policy, as well as to evaluate their effectiveness. Studies using the adapted version of the scale (MAS-UA) will allow the comparison of results from other countries where other language versions are used.

Published: February 2024

Ambient temperature is a critical factor that affects biological organisms in many ways. In this study, the authors investigated gene expression changes in Min pig muscle in response to cold stress. Female Min pigs were randomly divided into control and cold-stressed groups. Control group was housed at 10±2°C; the cold-stressed group was housed at –20±3°C for 13 days. The results showed that 34 genes were differentially expressed, of which 7 genes were significantly upregulated and 27 genes were significantly downregulated. Subsequent bioinformatics analyses revealed that the differentially expressed genes were mainly related to immune response, response to virus, and RNA binding. The bioinformatics analysis of the differentially expressed genes should be beneficial to further investigations on the underlying mechanisms involved in cold stress–induced damage in the muscle.

The Global Maritime Fulcrum as A Strategic Narrative: A Critical Examination of Its Emergence, Conveyance, and Decline in Indonesian Strategic Discourse
Authors: Agastia I Gusti Bagus Dharma
Published: February 2024

In 2014, President Joko ‘Jokowi’ Widodo declared he would lead Indonesia, the most populous Muslim nation on earth, to become a ‘global maritime fulcrum’ (GMF). His announcement was taken as a sign of Indonesia’s commitment to be a more active participant in regional maritime security. This nascent maritime vision, however, suffers from endogenous flaws, ranging from personal leadership to widespread bureaucratic deficiencies, culminating in its recession from Indonesian political discourse. This paper seeks to understand how and why the GMF receded from political discourse through the lens of strategic narrative. It finds that technocratic appeal serves as a stronger legitimating method of the GMF compared to other forms, which is due to agential preferences aligning with domestic structural conditions, resulting in development narratives being favoured over maritime-related narratives. The relationship results in government priorities being skewed towards the infrastructure aspect of the GMF at the cost of the other aspects. To demonstrate this argument, this paper analyses an original dataset of 267 speeches and statements, both in English and Indonesian, delivered by key government officials related to formulating and implementing the GMF concept from 2014 to 2021, in addition to relevant policy documents.

Published: February 2024

The popularity of the local Javanese music “Dangdut Campursari” increased dramatically from 2019 to 2020. Didi Kempot, who is nicknamed the God Father of Broken Heart, is a new phenomenon in Javanese music in the country. This research wants to see how the modern Campursari dangdut lovers “Sobat Ambyar” describe the identity of their community and see this phenomenon from the perspective of popular culture which includes trends, adaptability, and pop music consumerism. We documented Sobat Ambyar’s chat on social media, they managed and conducted in-depth interviews with the Instagram fanbase admin @sobatambyar. The results of this study indicated that Sobat Ambyar identifies themselves with the feelings, attitudes, and emotions of the songs sung by Didi Kempot. These identities tend to be sad and they are proud of that sadness. This Campursari has become a new commodity for industry and is popularized through the ways of modern culture which is simulated and marketed. Based on these findings, this study suggests that Sobat Ambyar remain authentic so that they can block mass culture that the younger generation is not aware of.Keyword : Fans, Instagram, Modern Campursari Music, Sobat Ambyar.

Perceptions of GIM therapists transitioning from in-person GIM sessions to online platforms during Covid-19 restriction
Authors: Grocke Denise , McFerran Katrina
Published: February 2024

In March 2020, when COVID-19 was declared a pandemic, therapists were required to make the transition from in-person, face-to-face sessions with clients to online telehealth sessions. The challenges for therapists practising The Bonny Method of Guided Imagery and Music were particularly difficult. This study was conceived to understand how GIM therapists managed the transition and how they perceived the differences of in-person and online sessions. Seven therapists, all female, living and working in Australia completed in-depth interviews in June 2022 about each element of the session, and a thematic analysis identified grand themes and subordinate themes. Results show that there was a dislocation of physical, personal and therapy space online, with absent cues and missed opportunities for caregiving. Rapport was established online and the therapeutic process developed, but the components of the GIM session were not the same, and the transition for the therapist was challenging. Findings indicate that online GIM sessions may provide greater opportunity and immediacy for people to have therapy and experience GIM, but in-person GIM may provide greater safety and greater depth of experience. Limitations and future research recommendations are presented.
“That’s what makes me authentic, because what we domakes sense” – Music professionals’ experiences of authenticity: A phenomenological, hermeneutical interview study
Authors: Ørnholt Bøtker Julie , Christensen Turid Nørlund , Jacobsen Stine Lindahl
Published: February 2024

Within music education, music therapy, and music performance theory, various perspectives on the concept of authenticity have been discussed and investigated. Authenticity seems to be a concept with wide possibilities for application and likewise wide definitional borders, which makes it hard to investigate. Drawing on the knowledge and framework developed by Bøtker and Jacobsen (2023), we wish to continue the investigation of authenticity within three music professions from a practice-based perspective. For this study, music therapists, music educators, and music performers (six participants) were interviewed twice about their experiences of their own authenticity when facilitating musical activities with children and adults (parents or teachers). The interviews were transcribed and analysed using a thematic coding analysis: deductively using the conceptual framework by Bøtker and Jacobsen as well as inductively by looking for new emerging themes across these three professions. The findings confirm the conceptual framework but also suggest an expansion, adding the element of ‘Values’. The new framework consists of six elements that all pertain to the experience of authenticity: relationship, role, context, professionalism, personality, and values. Furthermore, another theme appeared through the inductive analysis – ‘floating-anchoring’ – describing and synthesising the connection between the reflective and the sensorial awareness that supplement each other in the experience of authenticity within these three music professions. This floating-anchoring synthesis is suggested as a relevant framework for training and education within the three music professions.

In agriculture, one of the future solutions to eliminate the negative effect on the environment of the classical machineries is to use mobile robots. Small groups of mobile robots will interact with each other in order to inspect, to process or to harvest crops. These robots will have to work in a changing environment, in terms of terrain or road surfaces, the light of the ambient, animals, etc., aspects that will pose challenges for mobile robots. To facilitate the use of robots in agriculture, they must have a simple construction, be extremely reliable, flexible and, last but not least, cheap. These aspects have as effect new challenges for robot manufacturers to find technical solutions to meet the mentioned requirements. In this paper, a conceptual design and modeling of a mobile manipulator with hybrid locomotion, which may be used in agriculture for applications, such as tilling, seeding, weeding, etc, will be discussed.

The relationship of amyloidogenesis and taupathy with clinical outcomes of cerebral ischemia. Experimental research
Authors:   Pyatigorsk Medical and Pharmaceutical Institute — branch of the Volga State Medical University, Pozdnyakov D.I.
Published: February 2024

Currently, it has been established that increased formation of β-amyloid and tau protein play a significant role in the pathogenesis of cerebral ischemia. At the same time, these molecules can act as prognostic markers of the severity of cerebral ischemia. The aim of the study. To evaluate the peculiarities of changes in the concentration of β-amyloid and tau protein in blood serum and cerebrospinal fluid in rats with experimental subtotal cerebral ischemia, as well as to establish their relationship with the severity of post-ischemic clinical changes. Materials and methods. Subtotal cerebral ischemia was modeled by simultaneous occlusion of common carotid arteries in Wistar rats. The study assessed changes in neurological, sensorimotor and cognitive deficits. The content of β-amyloid and tau protein was assessed in blood serum and cerebrospinal fluid on the 1st, 3rd, 5th and 7th days of ischemia. During the analysis, species-specific kits for solid-phase enzyme immunoassay were used. Results. It was found that in animals with subtotal cerebral ischemia, as the duration of the ischemic period increases from day 1 to day 7, the concentration of β-amyloid and tau protein in both blood serum and cerebrospinal fluid progressively increases. It is worth noting that these changes strongly correlated with changes in the clinical manifestations of cerebral ischemia — neurological, sensorimotor and cognitive deficits.

Published: February 2024

Changes in the water-salt balance and excretion of ions by the kidney after subcutaneous injections of hypertonic and isotonic NaCl solutions and dehydration were analyzed in lake frogs (Pelophylax ridibundus). The introduction of 0,75 M NaCl and dehydration for 1 hour increased the serum osmolality and Na+ and Cl– concentrations, and injections of isotonic solution did not affect these parameters. The applied treatments increased the level of Na+ and Cl– in the urine, and renal excretion of these ions. The most pronounced changes, including an increase in diuresis and glomerular filtration rate, were found after 0,75 М NaCl injection. In renal proximal tubules, changes in the pattern of the chloride channel (ClC-5), presumably involved in the process of protein endocytosis, were detected. An increase in the number of ClC-5-immunopositive tubule profiles and the intensity of the fluorescent signal in the apical cytoplasm of epithelial cells were revealed by immunohistochemistry and confocal microscopy. Studied effects of hypernatremia, hypervolemia and dehydration may be useful for further investigations of kidney function and mechanisms of epithelial tubular transport in frog models.

Published: February 2024

The need to risk assessment of reproductive and ontogenetic toxicity of a medicine depends on a number of factors such as the properties of the drug, indications for use and the target patient population. It should be noted that this type of research is widespread. To increase the reliability of the of research data interpretation, the evaluation of the results should include not only comparison with control values, but also with reference values obtained in the same test center. The purpose of the study was the creation of reference intervals for the main indicators evaluated in studies of developmental and reproductive toxicity for Wistar rats. To calculate the reference intervals, the data obtained in the course of research at RMC “HOME OF PHARMACY” in the period from 2015 to 2021. Animals of the control groups were used to calculate the reference intervals. All manipulations and experiments are approved by the bioethical commission. Prenatal development was assessed by indicators: the number of live and dead fetuses, corpus luteum, implantation sites, pre- and post-implantation death was calculated. In the postnatal period, body weight was measured weekly in rat pups, a number of physiological parameters and the rate of maturation of sensory-motor reflexes were evaluated. For the data, a nonparametric method for determining reference intervals was applied. The most variable indicators are the number of implantation sites, the percentage of pre- and post-implantation death and the time of testicular descent, which must be taken into account when analyzing the data obtained. It is shown that the values of reference intervals obtained by us are generally comparable with the literature data.

Published: February 2024

Aim:
This study assessed the clinical impact and cost–effectiveness of switching from tenofovir disoproxil fumarate (TDF) to either tenofovir alafenamide (TAF) or entecavir (ETV) in a Greek chronic hepatitis B (CHB) population.
Patients & methods:
A Markov model from the perspective of a third-party payer in Greece quantified the health and economic benefits of switching from TDF to either TAF or ETV over a lifetime horizon.
Results:
Over a lifetime, patients who switch from TDF to TAF versus patients who switch from TDF to ETV had an overall lower incidence of compensated cirrhosis (0.4% lower), decompensated cirrhosis (0.04% lower) and hepatocellular carcinoma (0.25% lower). Chronic kidney disease and end-stage renal disease were also lower in patients who switch to TAF; major osteoporotic fractures were similar for both groups. While total costs were higher for switching from TDF to TAF versus TDF to ETV due to the higher cost of TAF, switching from TDF to TAF versus ETV was cost effective with an incremental cost–effectiveness ratio of €17,113 per quality-adjusted life year.
Conclusion:
Switching from TDF to TAF in patients living with CHB is a cost effective strategy to reduce adverse liver disease outcomes, while improving bone- and renal-related safety outcomes.

The design brief required a facility that would have a capability to test models at a commercial scale but that would be effective as teaching environment for the next generation of Naval Architects as well as providing a flexible space for future fundamental research. Each of these provided their own challenges but the eventual solution of a 138 m long, 3.5 m deep, 6 m wide facility has more than met the initial aspirations. Equipped with 12 independent 0.5 m wavemaking flaps at the West end, a passive beach at the East end, a deployable side beach along the South wall for post run wave absorption and a monocoque Aluminium alloy carriage, the Boldrewood towing tank has now been successfully operating for more than a year. The carriage position and speed are controlled by a twin winch arrangement using a laser positioning system and low embodied energy composite cables. The carriage can reach a maximum speed of 10 m/s with controllable acceleration rates and can have up to four constant speed phases per run. Initial commissioning results and comparisons with benchmark data for the KCS hull confirm the accuracy and repeatability of the facility. In particular, the position and speed of the carriage are known to a high level of precision. To date research and consultancy work has spanned the performance of high speed vessels, uncrewed underwater and surface vessels, wave energy and tidal current systems, floating platforms for wind turbines, performance sport work for sailing, kayaking, rowing and swimming, open water propeller tests as well as conventional displacement vessel testing for self-propulsion and resistance. All ship science and maritime engineering students use the facility as part of their taught modules in every year of their programme as well as for individual, MSc and group projects as appropriate. It has also made a strong impact on the many thousands of visitors a year to the campus for science and engineering open days.

Nonylphenol is a very important product for the chemical industry due to its widespread use as a base for several other chemical products. Among the major industrial sectors that use nonylphenol is the production of non-ionic surfactants, which are used from the home and personal care industry to the agrochemical industry. This study aims to define the optimal or quasi-optimal operating conditions for the separation system, which is composed of packed columns. Using simulation tools, the best operating conditions are attained, and the dinonylphenol subproduct generation is minimized. The commercial simulator Aspen Plus® was used for this study as the analysis tool for the mentioned objectives. The developed model is validated with technical data, measures are taken in a nonylphenol plant, and parameters are used in the same plant. From the obtained data from the plant, the best process performance is evaluated regarding cost-benefit analysis and safety concerns. The study shows a potential to reduce the subproduct production by 30% and the reboilers’ heat loads by 2%.

Background: The global population is undergoing rapid aging, highlighting the importance of assessing the hope levels of the elderly to develop educational and welfare programs aimed at enhancing their quality of life. This study aimed to assess the state of hope and its associated factors among elderly individuals in Birjand city. Methods: This descriptive-correlational study included 441 elderly aged 60 and above from Birjand City, selected using a systematic stratified sampling method in 2018. Data were collected through interviews conducted by trained interviewers using the standard questionnaire “Schneider's Hope of the Elderly (SHS)." Data were analyzed using SPSS 19 software, and statistical tests, including independent T-Test, ANOVA, and Tukey's post hoc test, were applied at a significance level of α = 0.05. Results: The average age of the participants was 70.1 ± 7.3 years. The mean scores for hope, agentive thinking, and strategic thinking were 27 ± 3.3, 12.9 ± 2.1, and 14.1 ± 2.1, respectively. Men had significantly higher scores in agentive thinking (P < 0.001) and the overall hope score (P < 0.003) compared to women. Illiterate individuals had lower agentive thinking scores than other groups (P < 0.001). Additionally, married individuals had significantly higher scores in agentive thinking, strategic thinking, and overall hope scores compared to other elderly individuals. Conversely, elderly individuals without children had lower scores in these areas compared to other groups (P < 0.05). Conclusions: Based on the study's findings, it is essential to develop and implement educational and welfare interventions aimed at increasing hope among the elderly, particularly targeting women, single individuals, those who are lonely, and those with lower levels of education.
Fragmentos de periferias urbanas contemporáneas, contexto de proyecto

Uno de los retos urbanos contemporáneos es el de las periferias urbanas. Sus formas surgidas en los márgenes de la ciudad, se originan a partir de fragmentos añadidos a la ciudad construida, desafiando los límites y proponiendo la nueva ciudad. Un territorio de contrastes, impreciso y cambiante en su propia naturaleza, que plantea un reto su descripción, interpretación, valoración y en consecuencia un desafío para su efectiva intervención. Para esta aproximación se ha trabajado sobre la idea de periferia en sus diversas escalas de intervención, teniendo en cuenta tanto las lógicas del conjunto como las individuales de cada fragmento. Ensayos de representación y miradas contrapuestas sobre estos territorios buscan profundizar en cómo mejorar las periferias desde un punto de vista morfológico y espacial para potenciar su habitabilidad. Revertir esta condición, que los convierte en frágiles y vulnerables, continúa presente en los diversos contextos urbanos en los que se manifiesta. Las miradas entrecruzadas sobre el proyecto de las periferias urbanas, permiten reconocer y caracterizar de manera más precisas situaciones territoriales diversas y orientar propuestas y formas urbanas futuras como base a nuevas lógicas proyectuales.

One of the contemporary urban challenges is urban peripheries. Its forms emerged on the margins of the city, originating from fragments added to the built city, defying the boundaries and proposing the new city. A territory of contrasts, imprecise and changing in its very nature, which poses a challenge for its description, interpretation, assessment and consequently a challenge for its effective intervention. For this approach, we have worked on the idea of periphery in its various scales of intervention, taking into account both the logic of the whole and the individual logic of each fragment. Essays of representation and contrasting views on these territories seek to delve into how to improve the peripheries from a morphological and spatial point of view to enhance their habitability. Reversing this condition, which makes them fragile and vulnerable, continues to be present in the various urban contexts in which it manifests itself. The intersecting views on the project of urban peripheries, allow us to recognize and more precisely characterize diverse territorial situations and guide future proposals and urban forms as a basis for new project logics.
Tesoros de la Lengua Mexicana

Recuerdo mi primera visita a la Ciudad de México. Olor, sabor, vida. La multitud de sensaciones que tuve resultaron ser tan profundas que han hecho una enorme hendidura en mi cerebro. Ahora siento que no soy capaz de pensar nada sin localizarme en un punto desconocido de ese mar de agua y pensamiento que une a México con Galicia (y, claro, también con España). No puedo olvidar una de las comidas que hice cuando, sin saber qué iba a comer, decidí probar el huachinango. Para mí, en aquel momento, era una aventura. Un riesgo que no sabía bien hacia donde me dirigía. ¿Qué es? ¿Cómo sabrá? Estaba muy sabroso pero, paradójicamente, no me sorprendió. Posiblemente ya que, como bien nos muestra este interesante libro, es una especie de pargo y, por tanto, también es conocido en otras partes del mundo. Nuevamente ese punto de conexión esa relación hermana.
Controlling Corruption Crimes In Indonesian Public Officials Using Multiple Factor Approaches

The research aims to examine the control of corruption crimes in Indonesian public officials using multiple factor approaches. This research is qualitative research with primary data sources directly from the Corruption Eradication Commission with a period of 2028-2022 . The results of this research explain that corruption committed by public officials is a crime that involves exploiting power and authority to obtain personal economic gain. Corruption behavior becomes interesting to discuss by studying patterns so that we can predict future corruption behavior and find out how to prevent corruption crimes. This paper finds that corruption committed by public officials is a type of individual bureaucratic crime and governmental occupational crime. The individual type of bureaucratic crime is the type that most often occurs in corruption of public officials. There are 6 fields where corruption is carried out, where the field of development project licensing is the field where corruption occurs the most. The mode most often used in corruption of public officials is the abuse of authority followed by bribery behavior. Early theories of criminal behavior have been criticized because they emphasized one factor as the cause of crime. Factors such as inherited physical traits, biological inferiority, weak minds, emotional disorders, or poverty are described as the sole causes of crime. The multifactor approach in criminology grew out of differences in the single factor approach. Its adherents argue that crime must be understood in terms of the multiple contributions made by various factors. The assumption is that crime is the product of many biological, psychological, economic and social factors and that different crimes will be the result of different combinations of factors. Therefore, the 'correct' approach in criminology is an eclectic approach that emphasizes the identification and analysis of a variety of factors
