Published: September 2023

La innovación institucional apunta a la confluencia de las políticas públicas con el propósito de generar desarrollo económico para los sectores productivos de una determinada nación. Por lo que el propósito de este trabajo de investigación es analizar el impacto de la innovación institucional en el desarrollo del sector exportador de aguacate peruano de 1961 a 2017. Las herramientas metodológicas para la investigación y el desarrollo son el análisis de estructuras discretas y los modelos econométricos. La base de este arte se basa en la teoría del crecimiento de las exportaciones y el papel del país en el crecimiento de las exportaciones. En los principales resultados, se encontró que cambios en las reglas del juego (innovación institucional) dentro y fuera del país peruano impulsaron el desarrollo del sector exportador de aguacate peruano. Permitir la innovación desde el entorno organizativo y tecnológico tras la crisis agraria. En este sentido, la reversión de la crisis agraria (innovación institucional) no solo beneficia a la exportación de aguacates peruanos, sino que también cambia por completo el entorno organizativo y tecnológico en el que opera la industria para generar competitividad a largo plazo. De acuerdo con la revisión de la situación actual del sector de aguacate peruano, no se encontraron trabajos que aborden el origen del impacto de la innovación institucional en el sector, ni la relación entre el ambiente organizacional y la tecnología; esta investigación se considera un aporte al conocimiento de la investigación futura.

Authors: Gálvez Navarro Melina , Mora Quintanilla Emilio
Published: September 2023

Gracias a su riqueza natural, Costa Rica es hogar de distintas montañas en las cuales muchos senderistas y montañistas se adentran para practicar deporte. Sin embargo, estas actividades son escenario de distintos accidentes, muchos de los cuales surgen a raíz de una mala hidratación. Dichas eventualidades no siempre se dan por falta de agua, sino por la carencia de educación sobre una buena hidratación.

A partir de estos casos, surgió el objetivo de diseñar un gadget inteligente que pueda brindar ayuda para minimizar accidentes o muertes provocadas por una mala hidratación, y evitar el desarrollo de consecuencias corporales a causa de la deshidratación. Además, brindar una herramienta que permita guiar al usuario en lo que debe realizar en caso de verse en una emergencia donde se quede con poca agua o sin esta durante su recorrido.

Para resolver este problema, se hizo uso de análisis de lo existente, de la ergonomía, la perceptibilidad, la funcionalidad y la tecnología, con el fin de conceptualizar una idea, definir sus funciones y su forma; para luego ser llevada a un prototipo funcional que cumpla con las necesidades identificadas por medio del estudio de distintos casos e interacciones directas con usuarios. Basado en lo concluido mediante los estudios, se desarrolló un gadget inteligente que responde a las necesidades de los senderistas y montañistas.

Published: September 2023

In 2023, demands for the United Nations to take up a larger role in global tax governance are louder than ever before. Nevertheless, there is not yet a global consensus on the way forward. In this paper we investigate how the United Nations (UN) could create a more inclusive and effective space for international cooperation. We define the current governance architecture as an ‘international regime complex’, emphasising the fact that several institutions govern international tax cooperation, without there being a hierarchy between them. Based on evidence drawn from interviews with 33 government officials (mainly from lower-income countries) conducted from May to July 2023, and from literature reviews on global governance arrangements in other policy areas, we discuss what role the UN could take in this international regime complex.
CFD simulation of a vortex-controlled diffuser for a jet engine burner
Authors: Chijioke Emeka Gaius , Teodorczyk Andrzej
Published: September 2023

A computational flow analysis of an ideal vortex-controlled diffuser (VCD) was carried out. The simulation model used is the compressible Reynolds averaged Navier-Stokes equations(RANS), with the application of the RNG based k-ε turbulence model. The effects of important parameters like static pressure recovery, bleed fraction, position of bleed slot, have been studied and comparisons were made with respect to VCD without the bleed configuration and the following features were revealed: radial profiles of velocity at the inlet, mid-planes and exit planes, including diffuser effectiveness (i.e. static pressure recovery), diffuser efficiency, reattachment length and diffuser total pressure loss. Results obtained by applying the RNG turbulence model show an instantaneous improvement in the diffuser efficiency that happens at reasonably minimal suction rates. From the calculations, it has been verified and shown in the analysis that the effect of the bleed positioning offers advantages in relation to where it is located.

Authors: Susilowati Eky , Lestari Fatma
Published: September 2023

Introduction: Fire is a common risk in any industrial facility that uses combustible and flammable raw materials, products, or supporting materials. Among others, the pharmaceutical industry is exposed to such risk due to the application of flammable liquids including ethanol as a volatile solvent in production areas, which has the potential to form explosive atmospheres through evaporation from pools created by accidental releases. Therefore, this study aims to analyze the hazardous area classification (HAC) in ethanol storage areas to facilitate the execution of risk mitigation efforts for reducing the role of ignition sources that cause fire and explosion. Methods: The HAC assessment was carried out in December 2021 - January 2022 using the quantitative method outlined in the International Electrotechnical Commission (IEC) standard: IEC/EN 60079-10-1 for zone determination. During flash point analysis, the ASTM D-93 method was employed to define the class of ethanol as a flammable liquid. Results: The ethanol storage areas fell into the zone 2 category based on the secondary grade of release, as well as the areas’ ventilation effectiveness with a medium dilution, and fair ventilation availability. The extent of zone 2 is up to 3 m from the release source. Conclusion: Ignition sources capable of leading to fire and explosion incidents in ethanol storage areas should be controlled.

Published: September 2023

Introduction: TBS textile factory is one of several textile factories where the process of fabrics dyeing takes place. In the process, workers lift and transport cloth loads manually, and thus work routines make their body bend. TBS textile factory ignored the health and safety aspects of work procedures which could cause worker fatigue. Safe work behaviour may prevent occupational sickness if the company applies appropriate occupational safety and health procedures. The purpose of this study was to determine the reduction of worker fatigue in the dyeing process of woven fabrics by applying occupational safety and health procedures. Methods: This study used treatment by subject design, where all samples were subjected to control and treatment, in different time periods. In this design, the interval between the time periods required washing out and adaptation, to eliminate the effects of previous work. The research population were workers in charge of dyeing section at TBS textile factory located in Gianyar regency. This study was conducted in July 2021 by involving 20 samples selected through purposive sampling technique. Data were collected from occupational safety and health procedures (how workers lifted and transported loads), legal limitations, and worker postures. Data analysis was carried out using t-independent test. Results: There was a decrease in scores of worker fatigue. The two different tests showed the scores after the study were significantly different (p < 0.05). Conclusion: Occupational safety and health procedures can reduce fatigue among workers in charge of fabrics dyeing by 40.77%.

#ShutItAllDown social protest: Examining emotional content on Twitter against sexual gender-based violence in Namibia
Authors: Eniayejuni Anthony
Published: September 2023

Over the years, social media has evolved into the primary platform for political activism. Citizens have utilized social media platforms to mobilize people to band together and rise against injustice. Social protests usually occur because of citizens’ emotional reactions to perceptions of injustice. Citizens have traditionally used social protests to voice their dissatisfaction with government policies and to influence political reforms. Citizens’ participation in social protests is fraught with emotion. Emotions elicited by political stimuli play a vital role in initiating and guiding goal-directed behavior. Therefore, this study intends to analyze the emotions expressed in Twitter posts during the #ShutItAllDown social protest. This study uses a quantitative approach. The findings show that both positive and negative emotions expressed on social media accelerate Namibian youth participation in the #ShutItAllDown social protests. Fear, anger, and anticipation instigate people’s participation in protests, whereas joy and happiness are feelings of satisfaction that are experienced during goal achievement. Thus, protest participation arising from both positive and negative emotions enforces government reforms.
The dichotomy of electoral choice in fragmented societies: Prospects of 2023 Nigerian general elections
Authors: Adewumi Adeyinka Patrick
Published: September 2023

Elections in fragmented states are usually contested along the divisive lines present within the geo polity, and this plays an important role in the emergence of political leaders. Nigeria, one of the most heterogeneous countries in the world, has exhibited predominantly ethnic voting since the consolidation of its fourth republic, and this has contributed to mixed socioeconomic and political fortunes. Using a qualitative approach based on secondary sources such as, books, journals, articles, this study highlights that mature democracies exhibit retrospective voting, through which objective scrutiny of government performance in the economy and other aspects of the state is done to determine whether to reward or punish political leaders at the polls. The limitations of primal and ethnic voting considerations in Nigeria, visible in development outcomes, call for a new guardrail to electoral choice. This paper argues the need for economic voting to predominate the ethnic considerations that determine electoral choice, as this can guarantee developmental outputs, and ensure political accountability that benefit the state. This study concludes that, if Nigeria is to experience significant changes in its fortunes going forward, the 2023 elections must change the narrative from non-evaluative considerations to evaluative voting considerations, for positive socioeconomic dividends.

Published: September 2023

Technological developments in the world are increasingly advanced and developing, various technologies have developed that make it easier for people in various ways. One that has an impact on these technological developments is on Notary services, developing electronic-based services or what is called Cyber Notary. However, in Indonesia, the application of Cyber Notary is still very limited, because there is no legal certainty that regulates it. Therefore, this study raises two problem formulations, namely: first, How is the Implementation of Cyber Notary in Indonesia based on the Notary Office Law? and secondly, what is the legal position of a cyber notary-based notary deed? The research method used is normative juridical with literature study using secondary data. The results of the study concluded, First, the application of Cyber Notary in Indonesia has not been fully implemented, because there are still no definite regulations governing the authenticity of deeds made using an electronic system. Second, in the event that the worst possibility occurs where the Notary Deed made electronically will be assumed to be a private Deed, hence this will not become a legal problem as long as the parties do not reject it and Government Agencies should also be able to accept it properly.

Authors: Diva Abigail Amara
Published: September 2023

This study aims to examine the criminal act of alleged forgery of authentic deeds and the state of notary legal protection. An authentic deed is a formal truth that concerns any matter and is notified by the parties to the Notary which is then contained in a deed. However, in practice, a good number od unlawful acts have occurred because the public has provided information that is not in accordance with the authentic deeds and providing fake documents. Hence the Notary can be harmed in this case. This study has a formulation of the problem, namely how is the condition of the notary's legal protection against the alleged crime of forgery of deed? The research method used is Juridical Empirical with statutory approach. The results of the study conclude that there is a state of legal protection for alleged criminal acts if the violation committed is still in the position of a notary, not a personal violation. Legal protection for notaries is carried out by the Notary Honorary Council under the Law on Notary Positions. Criminal acts committed by a notary also violate the provisions of the Criminal Code and can be tried by investigators through procedures approved by the Notary Ethics Council.

This study examines the lawsuit filed by Anne against Eddy Widjaja as the Curator Team of PT Raka Media Swatama (in bankruptcy) and Yana Suryana as the Main Director of PT Raka Media Swatama based on the Central Jakarta Commercial Court Bankruptcy Decision No. 08/Pdt.Sus-Cancellation of Peace/2017/PN.Niaga.Jkt.Pst Juncto No.65/PKPU/2012/PN.Niaga.Jkt.Pst. In the list of bankruptcy assets, Eddy Widjaja included objects that had been purchased by Anne as a third party, then apply for a counterclaim (derden verzet) in the counterclaim number 09/Pdt.Sus.Gll/2019/PN.Niaga.Jkt.Pst Furthermore, Eddy Widjaja made an appeal and the Supreme Court has decided on number 749K/Pdt. Sus-Bankruptcy/2019 canceled the lawsuit filed by Anne. The formulation of the problem in this study is: how is the legal power of PPJB and determination of assets/bankruptcy boedel if the company is declared bankrupt and how is the legal protection of third parties so that they get their rights from companies that are declared bankrupt. This is a normative juridical research that was conducted using a statutory approach and a case approach. The results of the study show that the Supreme Court Decision is erred if the land and building objects are included in bankruptcy assets, because the transfer has been made in the form of a sale and purchase and has been paid in full, and there is a PPJB Deed made before a Notary. In addition, Anne has also met the qualifications of a good faith buyer according to SEMA Number 4 of 2016.

This research is motivated by the existence of legal dynamics in regulating the formation of notary positions and the determination of regional categories after the changes to the Notary Public Law (UUJN). The issues raised in this study include the background of the reformulation of the formation of notary positions and the determination of regional categories after the amendment of the UUJN and how the flow of arrangements for the formation of notary positions and the determination of regional categories after the amendment of UUJN. This study uses a normative juridical method with a statutory and analytical approach. The results of the study concluded: First, after the amendment of the UUJN there were 4 (four) Ministerial Regulations (Perkemenkumham) governing the formation of notary positions and the categories for determining areas including: Permenkumham No.36/2015 jo. Permenkumham No.26/2014, Permenkumhan No.27/2016, and what is currently in force is Permenkumham No.19/2021. The reason behind the formation setup of notary positions and categories for determining regions specifically requires rearrangement of previous regulations by taking into account population growth, economic growth and regional expansion. Second, the trajectory of setting up the formation of notary positions and determining regional categories begins with limiting the number of notaries to changing regional categories. However, at this time, Permenkumham No.19/2021 provides clarity regarding the procedures for filling in the notary position formation, collecting notary data and simplification of regional categories and specifically stipulating procedures for submitting applications for moving regions.

The Ijarah Muntakiyyah Bittamlik contract is a sharia contract related to leasing that is carried out by many banks, because it is run by a bank, the bank requires collateral, one of which is a mortgage as a form of prudence, but this is where an error arises in applying the mortgage guarantee with the Ijarah Muntakiyyah Bittamlik contract. Because of this, two formulations of the problem are obtained, namely first, how is the implementation of the ijarah Muhamiyyah bittamlik contract with guaranteed mortgage rights in a notary deed? Second, what are the legal consequences in the event of an error in the application of the ijarah Muhamiyyah bittamlik contract with the guarantee of mortgage rights in a notary deed? This type of legal research uses normative supported by empirical with a statutory approach. The results of the study concluded that first, the implementation of the deed with the Ijarah Muntakiyyah Bittamlik contract with collateral rights is not appropriate because the binding of the mortgage guarantee can be carried out if debt arises due to unpaid rent not against the Ijarah Muntakiiyah Bittamlik contract which is based on rent, Second, the application of the Ijarah Muntakiyyah Bittamlik contract is erred with the guarantee of mortgage rights resulting in the contract being fasid.

Authors: A'la Fiddin Yusfida
Published: September 2023

This paper is a report of experiment analysis on sentiment analysis in application review that explored the methods and the data. Application review contains a large amount of raw data that has been published by users in the form of text, image, audio, and video. The data can be converted into valuable information by using sentiment analysis. In this work, around 5000 Indonesian review in MyPertamina google play application are analyzed. The goal of this study was to investigate the effectiveness of using sentiment analysis to extract valuable insights from application reviews. Some techniques were applied during this work, such as data collection, pre-processing, feature extraction, TF-IDF text representation, machine learning modelling, and evaluation phase. The machine learning algorithms that we used are Linear Support Vector Classification (Linear SVC) and Multinomial Naive Bayes (Multinomial NB). The result shows both machine learning models present good performance in this data. The accuracy of Multinomial NB reaches 95%, while Linear SVC obtains 96% of accuracy. The results of the experiment suggest that both Linear SVC and Multinomial NB are well-suited for sentiment analysis tasks on Indonesian language data. Future work could include expanding the dataset to include reviews from a broader range of applications, or evaluating the performance of additional machine learning algorithms. In addition, word cloud analysis also performed in this experiment. The word cloud shows that positive and negative sentiment present some popular words which appear inside the review. It would also be interesting to conduct a deeper analysis of the word cloud results to identify common themes and trends in the positive and negative sentiments expressed in the reviews

Unconventional oil production started in the Bakken formation of North Dakota in 1953. For the first fifty years, the rate of drilling was slow and measured with the scope of activity driven by delineation development associated with naturally fractured structural features and higher permeability formation facies at the edges of the basin. Production got a boost with the advent of horizontal drilling in 1987. However, it was not until twenty years later with the advent of multi-stage hydraulic fracturing of the horizontal lateral that completion and stimulation design advanced to a level which allowed economic development across the whole basin – regardless of structure or existence of a high permeability "sweet spot" facies.

Through 2022, a total of 18,833 wells have been drilled and completed in the Bakken Petroleum System across the United States portion of the Williston Basin. Comparing geologic data, completions parameters and state-reported production results it is possible to understand the fundamental well completion and stimulation changes that have guided industry to develop economic well results over the past seventy years of development. These well completion and stimulation advances have provided industry the opportunity to move from core geologic "Tier 1" areas of the basin to what is referred to as "Tier 2" and "Tier 3" areas which are characterized by an absence of structurally induced natural fracturing or higher permeability geologic facies. In addition, recent drilling and completions optimization has allowed industry to economically develop lower pore pressure and higher water cuts areas that are geographically located away from the highest pressure, deepest part of the basin.

These completion advances have allowed the region to compete on a global scale with production that peaked at 1.49 Million bopd and has now stabilized at ~1.1 Million bopd.

Flooding drives considerable risks. Designing strategies to manage these risks is complicated by the often large uncertainty surrounding flood risk projections. Uncertainty surrounding riverine flood risks can stem from choices regarding boundary conditions, model structures, and parameters as well as interactions among hazards, exposures, and vulnerabilities. Flood risk assessment involves multiple research disciplines including the fields of atmospheric science, hydrology, and socioeconomics. A quantitative understanding of which factors contribute most to uncertainties surrounding flood hazards and risks can inform the design of mission-oriented research. Here we analyze a case study to rank the drivers of uncertainties surrounding riverine flood hazards and risks. We find that the projected flood risk is most sensitive to factors associated with flood hazards, rather than exposure and vulnerability: upstream discharge, river bed elevation, channel roughness, and the digital elevation model resolution. Our framework and results can help to improve flood-hazard and risk projections.

In the manufacture of steel rods, the subsequent accidents may cause colossal time and economic losses if certain abnormality cannot be found and handled in time. Therefore, it is necessary to achieve comprehensive supervision in the production which requires timely and precise recognition of steel abnormalities. The existing recognition method does not perform well in recognizing such abnormalities: Methods that rely on human observation or traditional image processing are computationally expensive and inefficient. In contrast, frame-based object detection methods suffer from the error of recognition due to the inability to extract temporal information. In this paper, we proposes an effective method based on YOWO for video-based steel abnormalities, which enjoys both high efficiency and high performance. Specifically, our method consists of two parts, a novel cliplink module and a temporal data augmentation technique. Contrast the previous approaches, our method can make better use of temporal information to recognize the steel abnormalities. To better validate the effectiveness of our method and address the data deficiency of this task, we also propose a domain-specific dataset for steel abnormalities recognition. In the dataset, we achieves 81.5 mAP in accuracy and 40 FPS in speed, which demonstrates the significant advantages of the improved method.

Background
Mucopolysaccharidosis (MPS) type VII is a storage disorder of autosomal recessive origin caused by a deficiency in a lysosomal enzyme that results in accumulation of glycosaminoglycans and in secondary metabolic pathway problems. It has systemic symptomatology that mainly includes progressive skeletal dysplasia, cardiovascular manifestations, hepatosplenomegaly, coarse facies and many other manifestations, with cognitive decline in most cases. A significant proportion of patients may present fetal hydrops. Pathogenic variations frequent in specific ethnic groups explain the higher incidence in some groups due to founder effect and/or endogamy. In Brazil, the variant most commonly found is the p.Leu176Phe. This study aims to investigate GUSB expression of the patient with MPSVII with a new mutation (p.Leu292Pro). Also, it has been investigating the ancestry 5 patients with MPS VII from Brazil regarding the Amerindian, African and European contribution.
Results
Analyses allowed the identification of different proportions in the population contribution in the sample of patients with MPSVII with the highest European contribution which is significantly different (p = 0.0031) from the African contribution. Relative expression analysis by the 2−ΔCT method that showed superior expression of the GUSB gene in the patient with MPSVII compared to the group without the disease. Relative the comparison among threshold cycles, 14/20 samples showed significantly different CT values for the patient with MPS VII when comparing the amplification cycles. The relatives also showed different values (p < 0.05) for the amplification cycles. The in silico prediction of the new variant indicated it as pathogenic by modifying a highly conserved region.
Conclusions
It has been indicated that the Leu176Phe mutation is possibly of European origin. There is a discrepancy between the levels of mRNA for GUSB and the amount of beta-glucuronidase synthesized. The p.Leu292Pro mutation is indicated as pathogenic, but its impact on the MPS VII phenotype still need to be fully elucidated.
