The impact of video meeting platform usage on employee's perspective to virtual burnout
Authors:   , Wong Ronald Hao-Yin , D'Innocenzo Lauren E
Published: August 2022

Video Meeting Platforms (VMP) have given people around the world the ability to see each other and collaborate from anywhere they choose in a way that was unimaginable just a decade ago. Technology adoption of VMPs had a massive acceleration due to the unprecedented times during the lockdowns of COVID in 2020. The focus of this study was to get a better understanding of how the usage of the video platforms themselves, as described as the number of meetings, the hours of meetings, percentage of their video being on, and percentage of speaking roles, impacted how employees felt, what they experienced, and ultimately how it may lead to a feeling of virtual burnout. To answer this question, we employed a mixed method approach including 15 semi structured interviews and 427 survey responses. The interviews were conducted with a phenomenological approach, coded, and examined through grounded theory. Overall, participants reported that using VMP gave them a sense of unease, having less time, being more tired and blurring days. Lastly, participants felt that they no longer had meaningful conversations with peers and felt that the platform has made connecting with colleagues less pleasurable. In our quantitative investigation, we found that VMP usage leads to greater conflict (time, environmental, and work family). Only the number of meetings attended in a day showed a significant relationship to increased cognitive utilization. Interestingly, having speaking roles in meetings significantly lowers an employee's conflict time and though not significant reduces the other conflicts as well as cognitive usage. When uncertainty was introduced, it significantly reduced the strength of the relationship between having a large percentage of meetings having the video being on and cognitive utilization. The more cognition that was used the greater professional isolation was experienced. The conflicts that were described all led to the feeling of virtual burnout causing amnesia however only conflict time was significant to disassociation of the employee from their employer. The increased usage of cognition also led to the feeling of virtual burnout. However, professional isolation, though was a weak positive relationship, did not significantly show an influence to virtual burnout. Lastly, the usage of VMPs directly relating to virtual burnout had a negative effect. Though most of the direct effects of the mediators leading to burnout were positive and significant, the introduction of usage of the VMPs reduced the effect leading to burnout. From these findings, organizations should evaluate how they can provide better guidance to using the platforms to create a better experience for their employee.
The Fragmentation of Television Audiences

Published: August 2022

The fragmentation of television audiences started years ago, as television viewing options began with three major networks, CBS, NBC, and ABC. As technology has evolved through the years, the number of viewing options for consumers have seemed immeasurable. The television viewing audience has fragmented into various levels and degrees, with people watching on a myriad of devices, at various times throughout the day, and with a changed appetite for on-demand content. This research seeks to explain how the television audience became fragmented and what that fragmentation means for future television and media leaders. By examining television audience fragmentation, the researcher strives to provide industry leaders with the insight and knowledge necessary to make the best business decisions possible moving forward. Through this study, the researcher compares the fragmentation of television audiences to the dot.com movement of the early 2000's and the housing market crash of the 2010's. The study aims to determine that the fragmentation of television audience exists, and that it is a problem that will affect the television viewing public and eventually the business side of the television industry. The researcher examines this hypothesis by designing and launching a survey targeted at and solicited to television professionals with presumed knowledge of television audience fragmentation. The researcher also interviews a media professor with knowledge specific to television audience fragmentation. This study also includes a review of the literature on television audiences, the history of television, and viewership measurement.
Back from the Brink

Veterans with anxiety, depression, or PTSD are at high risk for suicide; art therapy has proven beneficial for those veterans who participate ("2021 National Veteran Suicide Prevention Annual Report" 2021; Ramirez, 2016; Smith 2016). Research examining the benefits of arts engagement for veterans largely focuses on painting, drawing, listening to music, or going to a museum. There is a shortage of studies that examine the benefits of theatre-based engagement. Using a qualitative research approach, founders and facilitators of theatre-based programming for veterans were interviewed to discover how their programs are delivered to veterans. While the activities vary by organization, there are several similarities in how they are delivered and the barriers veterans face in engaging with these programs. The trends discovered through these interviews include: mental health as a barrier; the importance for facilitators to remain acutely aware of the veteran participant's needs; and the impacts and themes in the veteran participants' work. These trends can aid the arts and culture sector in understanding how to responsibly and ethically produce theatre programs for veterans struggling with mental health or reintegration.

Authors: Dağlı Eren , Büber Mustafa , Taspınar Yavuz Selim
Published: August 2022

Information about the reality of the traffic accident, the clearness of the roads and the status of the accident can be obtained from the traffic accident announcements. By using the words in the radio or telephone announcements, you can be informed about the status of the accident. Inferences can be made with machine learning methods using a large number of data. In this study, the accident situation was classified using three different machine learning methods using radio and telephone announcements in Istanbul in Turkey. The dataset contains 156.856 announcement data. Classifications were performed using Artificial Neural Network (ANN), k-Nearest Neighbor (kNN) and Decision Tree (DT) machine learning methods. Classification success was 92.1% in the classification made with the ANN model, 91% in the classification made with the kNN model, and 89.8% in the classification made with the DT model. Classification performances of the models were also analyzed with precision, recall, F-1 Score and specificity metrics. In addition, the estimation abilities of the models with ROC curves and AUC values were analyzed. In addition, the training and testing times of the models were also analyzed. It will be possible to use the suggested models to automatically detect the accident situation from the announcements. In this way, it is thought that the most accurate direction can be made by obtaining information about crew orientation, traffic jams and the size of the accident.

Published: August 2022

Background: Diagnosis of skin disorders that exhibit interface dermatitis is challenging in few scenarios. Despite sincere efforts, clinical examination per se can help us reach a handsome of differential diagnosis but not a gunshot specific diagnosis. Dermatopathology acts as a saviour to clinicians in such cases. Though histopathology is the gold standard, still one cannot make a “specific” diagnosis by histopathology alone because many have overlapping features. Therefore, the present study aims at the importance of clinicopathological correlation. The objectives were to study the clinical and histopathological features of various dermatoses, which exhibit interface dermatitis histopathologically and estimate clinicopathological concordance.

Methods: This was a cross-sectional study done on 50 patients attending outpatient department (OPD), with the lesions suggestive of dermatoses known to exhibit interface dermatitis histologically. Strobe guidelines were followed. After a thorough clinical examination, punch biopsies were done and observed microscopically to detect interface dermatitis, if present. Secondary pathological features were studied to assess clinicopathological concordance. Microsoft excel and statistical package for the social sciences (SPSS) 21.0 were used for data analysis.

Results: 76.74% cases were cases of lichen planus and its variants. The most common clinical presentation was papules. Among microscopic features, predominant finding was basal cell vacuolar change in epidermis (97.70% cases). Clinicopathological concordance was seen in 43 cases (83%). 7 cases were diagnosed solely based on histological correlation.

Conclusions: A myriad of dermatoses exhibit interface dermatitis as a primary pathological feature. Only an apt correlation of clinical features with secondary pathological features can lead to a specific diagnosis from a bunch of differential diagnoses.

Hybrid Work Patterns: A Latent Class Analysis of Platform Workers in Denmark
Authors: Kristiansen Jonas Hulgård , Larsen Trine Pernille , Ilsøe Anna
Published: August 2022

This paper presents a novel approach for studying differences and similarities among platform workers, by taking into account the wider labor market position of platform workers. Analytically, we seek inspiration from literature on labor market segmentation (SLM) and multiple jobholding (MJH) to nuance the often-dichotomized view of labor markets characterized by SLM theory. By using survey data from a set of additional questions tied to the Danish LFS, we apply latent class analysis models to discover patterns of labor market divisions among platform workers in Denmark. We identify three major groups of platform workers, and while all of them have multiple income sources, they have very different labor market positions in the traditional labor market. We categorize them as ‘established workers’, ‘transitional workers’, and ‘new labor market entrants’. These divisions point to marked differences among platform workers, implying that platform work is characterized by varying blends of labor market hybridity.
Exploring the Role of Sodium-Glucose Cotransporter as a New Target for Cancer Therapy
Authors: Bardaweel Sanaa , Issa Ahmad
Published: August 2022

Purpose: To evaluate the effects of SGLT2 inhibitors on the proliferation, tumorigenesis, migration, colony formation, apoptosis, selected gene expression pattern, and combination with known chemotherapeutic drugs in different human cancer cell lines. Methods:  The antiproliferative and combined effects of SGLT2 inhibitors were evaluated by MTT assay. Cell migration was assessed using wound-healing and colony formation assays. Apoptosis assay was conducted using annexin V-FITC/ propidium iodide staining. SGLT2 gene expression was determined using real-time PCR. Results: Canagliflozin, dapagliflozin, and ipragliflozin significantly inhibited the growth of different cancer cell lines in a dose and time-dependent manner. IC50 values after 48 hours of treatment with canagliflozin, ipragliflozin, and dapagliflozin ranged from 41.97 µM to 69.49 µM, 63.67 µM to 255.80 µM, and 167.7 µM to 435.70 µM in the examined cancer cell lines, respectively. The combined treatment of SGLT2 with doxorubicin and raloxifene separately resulted in a synergistic effect in Caco-2 and A-549 cell lines. On the other hand, the combination of SGLT2 inhibitors with cisplatin resulted in an antagonistic effect in A-549, Du-145, and Panc-1 cell lines. Canagliflozin and ipragliflozin inhibited cell migration and colony formation ability at IC50 and Sub-IC50 in the examined cancer cell lines. Canagliflozin and ipragliflozin significantly induced apoptosis at IC50 and Double-IC50 in the Du-145 cell line compared to the control. Real-time PCR showed that the treatment with 0.1 IC50 and 0.2 IC50 of both canagliflozin and ipragliflozin resulted in diminished RNA expression of SGLT2, VEGF, and Bcl-2 genes in the Du-145 cell line. Conclusion: SGLT2 inhibitors have antiproliferation, anti-tumorigenesis, and anti-migration effects and may induce apoptosis in cancer cells. In addition, treatment with SGLT2 inhibitors resulted in the downregulation of selected genes in the Du-145 cell line.
Mechanical analogue of the motions of an inhomogeneous fluid
Authors: Temnov A.N. , Yan Naing Oo
Published: August 2022

The article considers the homogeneous vortex motion of an inhomogeneous fluid in a stationary ellipsoidal cavity arbitrarily oriented with respect to the direction of a uniform gravity field using the Lagrange variables. Uniform vortex motion of a fluid is a motion in which the rotor speed for all particles has the same value, and depends only on time. The article shows that the equations of homogeneous vortex motion of a heavy inhomogeneous fluid are possible in an ellipsoidal cavity with a linear density distribution and proposes a geometric interpretation of fluid motion.
Using the Lagrange variables, the equations of motion of an inhomogeneous fluid are obtained, coinciding with the equations of a heavy rigid body motion around a fixed point, written in a fixed coordinate system arbitrarily located relative to the direction of a homogeneous gravity field.
Experimental-analytical study of the occurrence of fuel splash through the air intake pipe of the emulsion atomizer

Published: August 2022

The study centers around an injector with gas-dynamic fuel atomization, i.e. an emulsion atomizer, which is not widely spread as the operating processes inside its channel and at its outlet at critical values of gas pressures and temperatures are poorly studied. First, we analyzed experimental data on the study of the fuel splash from the air intake pipe of the emulsion atomizer at various values of the oncoming air flow and the geometrical parameters of the outlet openings of the atomizer and evaluated the splash in terms of the gas dynamics of air flows inside the atomizer. Then, we developed a model that described the conditions for a fuel splash to occur from the point of view of the kinematics of the drops’ movement, and attempted to physically justify why the model was preferable. Next, we applied an analytical method to obtain a characteristic complex that linked the fuel splash phenomenon with the operating modes and geometrical parameters of the fuel distribution device. Analytical calculations made it possible to summarize the available experimental data and to obtain a graphical dependence, showing the boundary of the occurrence of a fuel splash from the air intake pipe of the emulsion atomizer. Finally, we gave recommendations to prevent the occurrence of a splash.

Published: August 2022

In recent years, Russia has been working on an option of creating a super-heavy-class Yenisei space rocket designed to implement long-range programs for exploring the Moon and deep space. At the moment, the project has been suspended, but the task is still relevant. The paper comparatively analyses the dynamic processes occurring at certain operational stages of the installation unit during the verticalization of the super-heavy-class Yenisei space rocket. In order to select their optimal design, we examined several designs of certain units and elements of the rocket verticalization system. The rocket configuration introduced in this paper was used to evaluate the functioning of the installation unit, whose design can be further modified for a new product. The relevance of the study lies in the analysis of specific operating modes of a fundamentally new type of installation units, which has not previously been used in Russia and the USSR. Relying on the calculations, we found the most suitable configuration of the nodes and elements of the verticalization system. Design solutions were proposed to reduce the dynamic loads on the rocket in the process of lifting and installation on the launch pad.
Diagnostically Cognitive Assessment of Complex Semantic Explanations and Learning: A Bayesian Network Approach
Authors: Zhang Zhidong
Published: August 2022

This study explored a diagnostically cognitive assessment model for the ANOVA score model emphasizing semantic explanations. The study used the mixed methods designs, in which the ANOVA score model was decomposed into measurable components. This consists of the proficiency student model. Such kinds of data were transferred to a quantitative representation via the Bayesian network model of the ANOVA score model and semantic explanation assessment. This diagnostically cognitive assessment consists of 28 variables hierarchically, which are explanatory variables and evidence variables. Nine variables are explanatory variables that are latent. Nineteen variables are evidence variables that collect students’ learning information and propagate the information to the explanatory variables. The data are simulated data; the semantic explanations from twelve students were recorded and input into the nineteen evidence variables. Semantic explanations indicate 3 levels: lower level, medium level and high level. The score should be more than 82 points, which indicates a mastery level. The study also suggests that if a student achieves a high score in a module, the student has a better chance of achieving a high score in the overall assessment model.

Authors: Ciferri Alberto , Soldi Angelaurelio , Bongianni Cinzia
Published: August 2022

Combinations of broad-defined indicators of wellbeing, social harmony, education, etc., have been used to provide comparative assessments of socio-economic conditions in various nations and stimulate policy changes. In this short review we compare conceptual frameworks and actual models based on subjective (social) and objective (analytical) socio-economic indicators. An interplay of subjective and objective indicators is also the basis of an approach for interdisciplinary education of young generations, particularly in nations characterized by ethnic conflicts and/or poor wealth distribution. The interaction between social and economic indicators suggests the need of a more integrated socio-economic outlook.
Capacidad productiva y pleno empleo: una alternativa de política
Authors: Ahedo García Mario Ricardo , Cruz Blanco Moritz Alberto
Published: August 2022

The aim of this paper is to propose the rate of productive capacity utilization as the economic policy target to fight unemployment. The idea behind this proposal is aimed at re-installing the management of effective demand as the main tool to reduce unemployment. This proposal attempts to replace the dominant theoretical framework, based on the neo-Keynesian labor market, which imposes inflation as the main restriction to reduce unemployment. We asses our proposal using data of six economies and several econometric techniques. The results indicate that the percentage of productive capacity utilization can indeed be a good substitute of the rate of unemployment. Moreover, according to the results of our panel data estimations, we identify that effective demand variables, like capital accumulation, affect productive capacity.
Eficiencia del combate a la violencia patrimonial en la Región Noroeste de México
Authors: Flegl Martin , Hernández Gress Eva Selene
Published: August 2022

The situation of violence in Mexico shows an alarming trend as the number of committed crimes increased by 10.9% in 2021 compared to 2020. In fact, 75.6% of the Mexican population perceives the insecurity. Due to the above, it is necessary to strengthen public security to combat this trend. However, the resources allocated to the public security in Mexico are limited. Although there are studies that investigate what causes the violence in Mexico, so far there is no study that measures the efficiency of combating the violence related to budgetary, human, and material resources of the public security. This article investigates the efficiency of combating the property violence in 206 municipalities in the Northwest region of Mexico through the Data Envelopment Analysis. The results show a low efficiency (56.67%) with significant differences between the states in the region. Baja California is the state with the lowest efficiency (17.61%), whereas the highest efficiency is found in Durango (67.25%). For the last, the need to carefully plan changes in the police force and the public security infrastructure was noted to improve the efficiency and the level of security.
What can a Game of Football in a Public Open Space tell Us about Our Socio-Economic and Political Condition? A Case of the City of Tshwane, South Africa
Authors: Makakavhule Kundani
Published: August 2022

This article focuses on sport and recreational activities, particularly football, in public open spaces in the City of Tshwane, South Africa. Using conflict theory, the article explores the different ways in which sport and recreation represent individual and collective conflicts regarding
the appropriation, perceptions, and experiences of urban public open spaces. Phenomenological qualitative research design was used to explore two case studies (parks) in the City of Tshwane. The research findings suggest that the conflicts due to sport and recreational activities in urban
public open space can be conceptualized as reflections of struggles for equitable state resources, subtle resistance and structural power dynamics. In addition, the article finds that sport and recreation in public open space are representations of memory, cultural identity, transforming values
and transforming spaces – all associated with the country's history.
Revisiting Public Space Transformations from a Sonic Perspective during the COVID-19 Pandemic
Authors: Bild Edda , Steele Daniel , Guastavino Catherine
Published: August 2022

The COVID-19 pandemic has changed how people relate to and use outdoor spaces, particularly in densely populated areas. We investigate the transformations that took place during the 2020 lockdown and the first post-lockdown summer, with an emphasis on changes to the sound environment,
in the context of a mixed-use central neighbourhood in Montreal (Plateau-Mont-Royal), Canada. Semi-structured interviews with thirteen residents, conducted in autumn 2020, showed how restrictions on the use of indoor spaces, including a ban on indoor gatherings, coupled with the transformation
of home environments into work, study, and relaxation spaces drove Montreal residents to engage more with outdoor public spaces in their neighbourhoods. This resulted in extended uses in terms of area, activities, duration of stay and even time of use, and in new uses for activities once restricted
to indoor spaces (e.g. family meals, celebrations). Sound played a critical role in these public space transformations, as the diversity of uses and activities brought back the sounds of human activity and even encouraged a sense of 'normality': a safe and shared form of coming together that
had been lost following the COVID-19 lockdown. The study highlighted the diverse, extended roles that (outdoor) public spaces can play in everyday urban life, beyond just providing access to quiet and the sonic consequences of this use in reinforcing previously paused forms of public life.
Furthermore, intentional forms of transformations of spaces, like pedestrianizations, offer flexible amenities, impromptu musical performances and organized socializing space and ful filled roles previously satisfied by third places and effectively became temporary 'fourth places'. These findings
provide grounds for reimagining the future of public spaces – not only in urban practice but also in the social imaginary, especially in relation to temporary interventions and programming, as well as promoting positive sound outcomes in public spaces.

Analysis of fault coupling vibration and transmission characteristics of multistage gear transmission system
Authors: Wei Hongbo , Wang Bingbo , Wang Xinbin , Wang Xin , Zhao Xiaofei
Published: August 2022

In multi-stage gear transmission system, the accident is often not caused by a single fault, but by coupling fault. The decoupling and identification of coupling faults has always been a hot topic. Through the analysis of frequency characteristics and transmission characteristics, this paper explored the correlation of coupling faults in multistage gear transmission system, and analyzed the coupling mechanism of faults. According to the fault test-bed, a 3D model was built to analyze the contact force and vibration characteristics of gears at all stages. STFT and waterfall diagram were used to analyze the coupling correlation characteristics of experimental signals under two single faults and coupling faults: fixed-axis gear crack and planetary gear wear. The contact force transfer function of all stages of gears to the box was built by using the system identification theory. The source of the fault characteristic frequency component was found through the transfer function, and the transmission characteristic of the fault was revealed. It can be seen from the results that the fault coupling is not the superposition of frequency characteristics. In the coupled signal, the frequency characteristic with the largest amplitude increase is not the fault gear itself, but the intermediate gear connected with them and affected by them. This phenomenon is often misled and misjudged in the analysis.

Authors: Gu Jun , Zhao Fei , Zhang Yao
Published: August 2022

Aiming at the small piston engine carbon deposition fault in the process of running, based on the cylinder pressure and cylinder head vibration signal of the engine, a fault diagnosis method combining variational mode decomposition and support vector machine is used to diagnose the engine carbon deposition fault. Firstly, particle swarm optimization algorithm is used to optimize the parameters of the variational mode decomposition. Then, the intrinsic mode function is obtained by processing the pressure signal and cylinder head vibration signal of the engine. Then, the singular spectrum entropy is calculated by singular value decomposition of the intrinsic mode function. Finally, the singular spectrum entropy is input into the support vector machine classifier as the feature data set for training and testing. The results show that this method can identify the carbon deposition fault of the starting motor well, and the accuracy of fault identification and classification of cylinder pressure and cylinder head vibration signal is 98.33 % and 99.17 % respectively, which verifies the effectiveness of this method.

Published: August 2022

Abstract: REST APIs are used by the majority of modern cloud and web services. This paper explains how an attacker can take advantage of REST API flaws to gain access to a service. We introduce four new security rules that take advantage of REST API’s and then demonstrate how a stateful REST API fuzzer can be extended with active property checkers that automatically test and identify violations of these rules. Then we talk about how to implement such checkers in both ways modularly and efficiently. Using these tools, we discovered new bugs in a number of production Azure and Office365 cloud services and discussed their security implications and resolve all these issues
A Data Analytics Approach to the Cyber Crime Underground Economy
Authors: Padmaja K. Vinaya , T Kalyani. , Rushalani T. , Ramasubramanian Dr. M.
Published: August 2022

Abstract: Despite the rapid escalation of cyber threats, there has still been little research into the foundations of the subject or methodologies that could serve to guide Information Systems researchers and practitioners who deal with cyber security. In addition, little is known about Crime-as-a-Service (CaaS), a criminal business model that underpins the cybercrime underground. This research gap and the practical cybercrime problems we face have motivated us to investigate the cybercrime underground economy by taking a data analytics approach from a design science perspective. To achieve this goal, we proposed data analysis framework for analyzing the cybercrime underground, CaaS and crime ware definitions, and an associated classification model. In addition, we develop an example application to demonstrate how the proposed framework and classification model could be implemented in practice. We then use this application to investigate the cybercrime underground economy by analyzing a large dataset obtained from the online hacking community. By taking a design science research approach, this study contributes to the design artifacts, foundations, and methodologies in this area. Moreover, it provides useful practical insights to practitioners by suggesting guidelines as to how governments and organizations in all industries can prepare for attacks by the cybercrime underground.

Abstract: Serial devices are the fundamental building elements of all digital electronic systems with memory. The non-volatile quality of sequential devices is necessary for quick data recovery after unexpected data loss, such as an unintentional power outage, which has sparked ongoing research and development into integrating a non-volatile memristor into CMOS devices. In this article, we examine using this technique to raise the caliber of nonvolatile D-latch. One memristor, a few transfer gates, and CMOS transducers are the sole components of the proposed D-latch, which sets it apart from conventional designs. Our design minimizes the negative impact of transistor threshold loss. In addition, a variety of memristor threshold values are available with our design

Abstract: Shied Metal Arc Welding is one of the most important joining processes in the industry. This type of welding is widely used in many areas like from industries to household in joining simple metal piece it mostly used due to its compatibility and cheap equipment’s cost because it due not require gas for shielding and its electrodes are also cheap. There are numerous studies and researches done around the world to understand geometry of SMAW welding under different operating conditions. Experiments are done considering various parameters of welding such as welding current, welding speed, welding voltage, welder skills etc. This helps in better acknowledgement of bead geometry of SMAW welding for maximum enhancement in various industries. in this research paper we have carried out an experiment on bead geometry of SMAW with varying current. After that we calculate the variation on the height of the reinforcement, depth of the penetration, width of the heat affected zone and the welded zone. In the experimental analysis, it is found that all the process parameter’s significantly affect the quality. The results revealed that the use of the optimum welding current parameters resulted in the improvements in the welded joint.

Abstract: In recent years, a lot of research is being carried out in the field of Named Entity Recognition of Social Media data. It is now easier for anyone to convey their opinions and information without any kind of authentication, rumours have multiplied as social media is now one of the commonly used media in the entire world. The fields in which Named Entity Recognition is used for analysis of data provided from various social media sites, include rumour detection, controversy detection, sentiment analysis, medical field (such as visualisation of the spread of COVID-19 or for various kinds of dietary concerns), topic detection and event detection. The purpose here is to present a summary of the present state of social media research and the impact created by information extracted from it. Through this paper, different methods proposed for the purpose of social media data extraction using Named Entity Recognition, have been studied in detail and a comparison has been provided for the same. Most of these papers use the most common metrics for evaluation of their performance, which includes precision, recall and accuracy. The proposed models have been tested on certain datasets extracted from social media networking sites such as twitter, facebook, etc. and their evaluated performance has been compared to the models proposed by several other similar approaches.

Las comunidades indígenas conservan sus prácticas locales en torno a los recursos naturales, las cuales contribuyena la conservación de la naturaleza y satisfacción de sus necesidades alimenticias y socioculturales. Elobjetivo de la investigación fue analizar las prácticas de aprovechamiento y manejo de los recursos naturales enespacios indígenas de Oaxaca. Se empleó el método etnoecológico, la entrevista estructurada y recorridos decampo. Se encontró que los entrevistados implementaron diferentes tipos de prácticas agrícolas, destacandola siembra de cultivos asociados o intercalados, la construcción de muros de retención (bordos) y terrazas yla nivelación. El manejo del suelo se realiza de forma diferenciada, en dos sitios utilizan estiércol de animalesde traspatio y en otra comunidad emplean desechos domésticos. Las prácticas de manejo del agua fuerondiferentes por comunidad y estuvieron sujetas a su cultura, destacó el manejo del agua de riego por gravedady en menor medida la cosecha de agua de lluvia. También fue frecuente la recolección de plantas, hongos y elaprovechamiento de animales silvestres. Aún se practican rituales dedicados al suelo, en menor medida al agua,a la montaña y a los animales. Se concluye que las comunidades de estudio conservan sus prácticas gestadaslocalmente.

Every child has human rights as well as the rights of adults, so respecting children's rights is the same as respecting human rights. This paper aims to compare the policy of imposing the death penalty on a child between Iran and Indonesia. This research is a normative legal research conducted by examining library materials or secondary data. The approach used is a comparative approach, which is to compare child protection laws between Iran and Indonesia. The regulation of criminal penalties against children in Iran is regulated in Article 91 of the Iranian Islamic Criminal Code in 2013 and in Indonesia it is regulated in Law Number 35 of 2014 concerning Child Protection and Law Number 11 of 2012 concerning the Child Criminal Justice System. The regulation of legal protection for children in Iran and in the State of Indonesia, when compared, has quite basic differences in several aspects of the provisions of criminal acts and the criminal system. In the criminal setting in Iran, it justifies the application of the death penalty for crimes committed by children under 18 years of age. In the last 7 years, almost all juvenile offenders who were executed were sentenced to death based on qisas and hudud verses. Meanwhile, in Indonesia, it does not apply the death penalty to children but prioritizes restorative justice and diversion which is intended to avoid and keep children away from the judicial process so as to avoid stigmatization of children in conflict with the law and it is hoped that children can return to the social environment naturally.
