An Ontology Framework for Generating Requirements Specification
Authors: Yanuarifiani Amarilis Putri , Chua Fang-Fang , Chan Gaik-Yee
Published: June 2020

Requirements engineering is the initial process of software development that critically determines the overall software process quality. However, this process is error-prone. This is generally related to the factors of communication, knowledge, and documentation. With the lack of business knowledge, it is complicated for (technical) engineers to define customer needs. Also, modeling and documenting requirements need much time and effort to ensure that the requirements are valid, and nothing is missed. The current approach of the requirements modeling process mostly focuses on the Unified Modeling Notation (UML) use case, that not provide enough information for a stakeholder to define system requirements. The generated SRS is still lack of detail development guideline that increase risk of development error. The purpose of this research is to guide for the elicitation process to avoid missing and mismatch requirements, and to make the modeling and documentation process more effective and efficient. We propose an ontology framework for generating requirements specification. This framework, namely the Rule-Based Ontology Framework (ROF) consists of two main processes: First, requirements elicitation. This step provides a guideline for the stakeholder to define system requirements based on the problem of the current system and business process enhancement. Based on this final requirement list, the requirements ontology is generated. Second, the auto-generation of the requirements specification document. The document consists of semi-formal modeling and natural language. In this research, we use Business Process Modeling Notation (BPMN) is a modeling language. For natural language documents, we use IEEE for the SRS template.

Published: June 2020

Knowledge, and experiences in software development have been accumulated over time throughout the project lifecycle. Previous studies have shown that the management of knowledge and experiences in software development has always been an issue. Therefore, the knowledge transfer and information flow are inefficient, misinterpretation, and inconsistencies always occur between individuals or teams, and the organization fails to learn from past projects. It is understood that efficient knowledge and experience management for software development organizations is crucial for the purpose of sharing and future reuse. This paper discusses the prototype development for a proposed model, which is based on the experience factory approach, to manage knowledge and experiences for the software development process. Discussions include the system functionalities and design, infrastructure requirements, and implementation approach. The efficiency and effectiveness of the prototype are evaluated as survey research based on Jennex & Olfman knowledge management success model. Rasch analysis is used for data reliability and validity. Results show positive feedback on the model’s efficiency and effectiveness. Additionally, as agreed by most respondents, the top three of the model contributions are: to encourage learning organization, to prevent knowledge loss and to aid in decision making.
Zsmell – Code Smell Detection for Open Source Software
Authors: Nanthaamornphong Aziz , Saeang Tanawat , Tularak Panyaprach
Published: June 2020

Today, open-source software (OSS) is used in various applications. It has played a vital role in information systems of many user groups such as commercials, research, education, public health, and tourism. It is also a source of additional knowledge for collaborators because this type of software is easily accessible through websites that provide management of version control services such as GitHub. However, a recent study shows an increasing trend in the existence of code smells. In OSS, there is a growing number of code smells that cause software errors. Having a code smell in software is a serious issue since it impacts the software in terms of deployment, maintenance as well as user confidence toward the software. Finding code smells in the early stages of software development would provide for better software maintenance and reliability; thus, researchers invented the Zsmell software system that helps search for code smells in the source code saved in GitHub. Developed systems display data related to code smells in each source code version that was modified by collaborators. Thus, the developers will be able to employ the proper refactoring method, which is a change in the internal structure of software without changing the original functionality of the software. We believe that this system will enable open source collaborators to improve the quality of their OSS, especially on code smell reduction and the understanding of various types of code smell commonly found in OSS projects.

The reduced mobility in hand is a problem that prevents daily activities such as feeding, bathing, brushing, dressing, grabbing objects, and losing autonomy in everyday situations. The hand disability is mainly due to the deficiency of the ulnar, medial, and radial nerves, which prevents adequate hand movements. In consequence, various assistive technologies are proposed to assist mobility, communication, self-help, and domestic activities. An alternative is the use of active orthosis, which by this proof of concept, the person can perform adequate hand movements. This paper aims to introduce a 3D active orthosis of PLA Plus designed by the Creative Lab in the Universidad Santiago de Cali, which includes an actuator and a low-cost myoelectric signal acquisition system, with two input channels. Finger flexion/extension movements and resting-state were performed. The user’s intention is decoded processing rectified and integrated myoelectric signals. An on-off control algorithm was implemented to generate commands that control orthosis movements. The system is controlled by a person who has a disability due to a C5 and C6 spinal trauma that generated muscular atrophy in the distal level of the hand. Results showed the controlled flexion and extension of the fingers with a good performance. This system assists people with disabilities in the ulnar, medial, and radial nerves to make proper hand movements. The design of the above-mentioned orthosis allows individuals to carry out daily living activities to improve their quality of life.

This paper presents a vibration analysis of an internal alternative combustion engine through frequency analysis and wavelet transform, where a form study of the temporary signal and the energy of that signal is carried out to extract certain  characteristic values that allow to differentiate and identify to which pre-established operating conditions, a specific vibration signal belongs. Software is used to make the data decomposition, analysis and value extraction. Different analysis results are presented on this investigation like frequency analysis, spectrogram analysis, wavelet analysis, cross wavelet analysis, and results validation by extracting values of the signals of two tests generating a variation chart showing runs variability if it is big o tiny variability. This analysis is performed to characterize the engine vibration signals so that it is possible to identify an incipient failure in a non-intrusive manner and optimize its maintenance. Also, it can be determined the repetitive form that describes a temporary signal of mechanical vibrations of a motor, if its work cycle it is considered to separate the temporary signal into sections, as long as there are no lower frequency components than the result of dividing the sampling frequency for the number of points that are in a work cycle (the limit frequency).

Published: June 2020

The application features of the Via-in-Pad method when implementing a high-density conductive pattern of multilayer switching structures in electronics is considered herein. The composition method for vias and contact pads for the tracing ability improvement is proposed, and the assessment methodology for the effective area utilization for BGA components is presented. The experimental study of the pressure sensor housing was carried out, which showed that the application of this method made it possible to reduce the number of vias by 40% and place more contact pads per unit area, which frees up the gaps for BGA tracing, reduces the pattern density and microwave signal paths. The obtained results confirmed the possibility of reduction of the usable space by 25%, which makes it possible to arrange more pads per unit area, to free up the gaps for BGA tracing, to reduce the time for drilling the workpieces, to reduce the number of used drills, and also provides the best heat removal from the components. The disadvantage is the large internal resistance of the transitions created by the Via-in-Pad method, in contrast to the standard ones, which can negatively affect the flow of critical signals. By comparing the resistances from the metallization layer of the via in the MPCB with a flexible flat cable and in the MPCB designed using the Via-in-Pad method, it was found that the Via-in-Pad method made it possible to increase the layout efficiency of multilayer printed circuit boards.

One hundred twenty-five female ducks, with an average body weight of 1485.51±14.72 g, aged eight weeks, were used in this experiment to examine the effect of ginger volatile oil (GVO) on the metabolic profile of the glycolytic pathways, free radical and antioxidant activity in heat-stressed Cihateup ducks. GVO isolation was carried out by the distillation technique. Cihateup duck samples were divided into five treatment groups, each group with 25 animals. Each treatment consisted of five replications so that each repetition consisted of 5 duck samples. The treatment in this study was A: temperature of the comfort zone (24°C) and without administration of GVO; B: heat stress (38°C) and without GVO; C: heat stress (38°C) and 150 µL GVO/tail; D: hot stress (38°C) and 200 µL GVO/tail, E: Hot stress (38°C) and 250 µL GVO/tail. GVO was given every morning orally (force-fed). The data then statistically analyzed with ANOVA procedure to determine the treatment effect. Duncan's multiple range test was used to compare the treatment effect. The results showed that the metabolic profile of the glycolytic pathway appeared to be in the normal range by administering 250 µL GVO. The reduction of free radicals activity and increased endogenous antioxidants (Glutathione Peroxidase) activity were also found in GVE treated ducks. In conclusion, the heat stress of Cihateup duck was reduced by administering the GVO.

Published: June 2020

Earthquake and Tsunami are one of the biggest disasters dealing with countries located in disaster-prone areas. A risk management and mitigation system are crucial for those countries to reduce the risk of disasters. Indonesia already started to pay attention to the disaster mitigation system since the tsunami that occurred in Aceh in 2004. Various initiatives to reduce the risk of the disaster have been started, the focus is by Increasing knowledge and raising awareness of hazards and the skills to manage disasters. By then, the mitigation system still not capable enough to reduce the risk of the disaster. This can be seen after the tsunami that occurred in Aceh, Indonesia faced a lot of earthquake and tsunami disasters until 2018 and caused severe damage in each incident. On the other hand, Japan's management and mitigation system facing the same disasters (earthquake and tsunami) had been proven most successful since the Great Hanshin-Awaji Earthquake in 1995. This research aims to analyze and compare both japan and Indonesia's strategies in disaster management and to find out the risk management and mitigation system that can reduce the risk of the earthquake and tsunami disaster. The result found out there is an application called “Disaster Reduction Class” developed by Prof. Akiyoshi Takagi that needs to be implied in Indonesia to reduce the risk of earthquake and tsunami disaster.

Authors: Anggraeni Palupi , Daniels Peter , Davey Peter
Published: June 2020

This paper analyses the relationship between natural resources endowment and economic welfare in Indonesia, and examines how to further benefit from natural resources through the factors of government institutions, industry value-added, and foreign direct investment (FDI). A sequential explanatory mixed-method design was used. It starts with a quantitative analysis using time-series data at the national level from 1990 to 2017 and continues with key-informant interviews to obtain further explanations from the quantitative analysis results. The findings show that the contribution of natural resources to economic welfare in Indonesia is positive only in the short term. It has helped build Indonesian development but has not been able to create economic welfare, especially for the local community. Improving institutional quality, primarily through environmental law enforcement, and increasing industry value-added, is important to create a bigger multiplier effect from natural resource rents that will benefit economic welfare. Nevertheless, FDI in the natural resource sector could be harmful to economic welfare; thus, it should be applied only to a capital intensive and high technology exploitation that State-owned enterprises are not capable of undertaking. This study also found that the regulation relates to natural resources revenue sharing needs to be improved, particularly in terms of the formula that use provincial boundaries for sharing distribution.

Limited number of sweet corn varieties specifically bred for organic cropping system has brought about the organic sweet corn growers use hybrid varieties supposedly grown under high agrochemical inputs cropping system. The objective of the present study was to evaluate the performance of sweet corn inbred lines and to estimate the genetic parameters as to the development of varieties suitable for organic cropping systems. Eight inbred lines of S5generation previously selected for yield and adaptability to organic conditions were evaluated in a randomized block design with seven replications. Performances and genetic parameter estimation were addressed to plant height, the number of leaves, stalk diameter, ear length, ear diameter, kernel row number, kernel number per row, and ear yield per plant. Significant variations were found among the inbred lines for all traits studied. Similar features were also found within the inbred line, except stalk diameter showed non-significant within-line variation. Evaluation of mean values indicated that CAPS 2 exhibited the best plant growth performances and produced reasonably high ear yield. CAPS 5 produced the highest ear yield along with superior ear length, ear diameter, and kernel row number. Broad sense heritability (h2B) were ranged from low to moderate with the higher estimates found on ear length (0.43) and ear yield per plant (0.40). Based on the estimates of genetic advance as percent of the population mean (GAM), moderate improvement can be expected from ear length (13.37%) and ear yield per plant (20.86%) by selecting the top 5% of the inbred line populations.

Published: June 2020

One of Floating Nuclear Power Plant (FNPP) designs in the world is currently being built by Russian Federation, named “Academic Lomonosov,” which uses two PWR types, KLT-40S as its power unit. However, too little information regarding its detailed technical specification is available, including its thermal-hydraulics parameters. The objective of this research is to create a thermal-hydraulic model of KLT-40S reactor core use RELAP5-3D and to predict fuel and cladding temperature value at the steady-state condition, and transient condition with a variety of primary coolant mass flow rate and pressure to simulate abnormal event within the reactor. The reactor thermal-hydraulic model is created by dividing 121 coolant channels in the actual nuclear fuel assemblies into two channels: one channel to simulate coolant flow in 120 fuel assemblies with average heat generation, and the other channel to simulate coolant flow in one fuel assembly with highest heat generation in the core. The fuel structure had solid cylinder geometry and made from ceramic-metal UO2 dispersed in the inert silumin matrix. The fuel cladding is made from zirconium alloy. These fuel heat structures generate heat from fission reaction and are modelled as a heat source according to the reactor power technical data, i.e., 150 MWt. The reactor axial power distribution is approximated by cosine distribution. Operation parameter variation that represents the real reactor normal operation condition in this research is a variation that has flow loss coefficient value 8,000, radial power peaking factor 1.1, and axial power peaking factor 1.1 with axial power peaking located in the middle of the fuel rod. The fuel and cladding temperature value at the steady-state condition and several transient conditions are predicted in this research, and there is no temperature value that goes beyond the safety limit.

Published: June 2020

Face Recognition is a well-known image analysis application in the branches of pattern recognition and computer vision. It utilizes the uniqueness of human facial characteristics for personnel identification and verification. For a long time, the recognition of facial expressions by using computer-based applications has been an active area of study to recognize face scheme through a face image database. It is used in a variety of essential fields of modern life such as security systems, criminal identification, video retrieval, passport and credit cards. In general, face recognition process can be summarized in three distinct steps: preprocessing, feature extraction, and classification. At first, histogram equalization and median filter are applied as preprocessing methods. Secondly, Gabor wavelets transform extracts the features of desirable facial characterized by, orientation selectivity, spatial locality, and spatial frequency to keep up the variations caused by the varying of facial expression and illumination. In addition to that, Principal Component Analysis methodology (PCA) is used in dimensionality reduction. At last, Support vector machine (SVM) is applied in classifying the feature of the image according to the classis of every mage. In order to test the approach used in this research, experiments were running on Yale database of 165 images from 15 individuals in MATLAB environment. The results obtained from the experiments confirmed the accuracy and robustness of the proposed system.

Published: June 2020

Rice straw is one of the agricultural residues that can be used to form a composite such as particleboard. In this study, the effect of rice straw particle size on the mechanical and physical properties of rice straw epoxy resin particleboard has been investigated. The rice straw particles sizes were varied for 40 mesh, 50 mesh, and 60 mesh. The ratio of rice straw to epoxy resin was also varied for 80 : 20 vol.%, 85 : 15 vol.%, 90 : 10 vol.%, and 95 : 5 vol.%. Our results revealed that the mechanical properties (modulus of elasticity, modulus of rupture, and tensile strength) of particleboard strongly depend on the rice straw particle size. This behavior is the same for the physical properties (density and water absorption) of particleboard. The highest flexural strength (modulus of rupture), elastic modulus, and tensile strength of rice straw epoxy resin particleboard are obtained at the 50 mesh of rice straw particle size with its value of 6.15 kgf/mm2, 3280 kgf/mm2, and 0.60 kgf/mm2, respectively. However, the highest density is obtained at the 60 mesh of rice straw particle size, which is 0.87 g/cm3. The lowest water absorption (23%) is also obtained at the 60 mesh of rice straw particle size. Our finding indicates that the particle size plays a vital role in the reinforcement of particleboard.
A Novel Android Memory Forensics for Discovering Remnant Data
Authors: Satrya Gandeva Bayu , Kurniawan Febrian
Published: June 2020

As recently updated on the vulnerability statistics shown in 2019, Android-driven smartphones, tablet PCs, and other Android devices are vulnerable, whether from internal or external threats. Most users store sensitive data like emails, photos, cloud storage access, and contact lists on Android smartphones. This information holds a growing-importance for the digital investigation process of mobile devices, e.g., internal memory or random-access memory (RAM) forensics, or external memory or read-only memory (ROM) forensics on Android smartphones. Internal memory retrieval is considered flawed and difficult by some researchers as it alters the digital evidence in an intrusive way. On the other hand, external memory retrieval also called logical acquisition that implies the image of logical storage items (e.g., files, database, directories, etc.) that locate on logical storage. This research provides a novel methodology that focuses only on internal memory forensic in a forensically sound manner. This research also contributes two algorithms, e.g., collect raw information (CRI) for parsing the raw data, and investigate raw information (IRI) for extracting the digital evidence to be more readable. This research conducted with fourteenth events to be analyzed, and each event was captured by SHA-1 as digital evidence. By using GDrive as the case study, the authors concluded that the proposed methodology could be used as guidance by forensics analyst(s), cyberlaw practitioner(s), and expert witness(es) in the court.

Published: June 2020

Tricyclazole, a systemic fungicide is recommended to treat of diseases in irrigated rice. Channa punctatus (Bloch) is a freshwater fish also found in paddy fields. This maiden study was designed to evaluate acute toxicity of tricyclazole and its responses of certain biomarker enzymes in Channa punctatus. By regression analysis method, 24, 48, 72 and 96hr-LC50 dose of tricyclazole was calculated 54.30, 36.76, 32.63 and 25.06 mg l-1 respectively. The range of LC50 dose indicates highly toxic nature of tricyclaozole. Fish were then exposed to 0.25 and 1.25 mg l-1 sublethal dose of tricyclazole for short term (24, 48 and 96 hours) and long term (15, 30 and 45 days) exposure and the alterations of enzyme activities were determined. Alkaline phosphatase activities exposed to 0.25 mg l-1 were increased insignificantly (p>0.05) after 24 hours but increased significantly (p less than 0.05) to 0.25 and 1.25 mg l-1 tricyclazole at all other treatments. Alanine transaminase and aspartate transaminase increased significantly (p less than 0.05) in response to tricyclazole during both exposures. These findings may be used in the assessment of the potential risk of tricyclazole on food chain and aquatic ecosystems.

Authors: Sládek L.
Published: June 2020

The aim of this study was to establish the impact of slaughter weight, sex and the intramuscular fat (IMF) content of the musculus longissimus lumborum et thoracis (MLLT) on the carcass value of (Czech Large White x Czech Landrace) x Duroc hybrid pigs. The average lean meat content was higher in gilts (56.51 %) than in barrows (55.89 %). Average IMF content was recorded as 3.76 % in barrows and 3.42 % in gilts. The slaughter weight of the pigs did have an impact on the IMF content of the MLLT. The higher average slaughter weight (121.61 kg or 120.68 kg) of pigs intended for slaughter was established in pigs with a higher average IMF content (3.52 % or 5.20 %). Neither sex nor slaughter weight affected the monitored indicators of meat colour. The IMF content of the MLLT had no significant impact on carcass value indicators.

Composite bone grafts were prepared by seeding of rabbit foetal osteoblast on the bovine acellular cancellous bone matrix and evaluated in the segmental gap defect of 20 mm in rabbits. Thirty six adult New Zealand White rabbits of either sex were allotted to three groups of 12 each. Autograft (group A), Acellular cancellous bone matrix (group B) and composite graft seeded with fetal osteoblasts (group C) were implanted in the defects. Radiography, gross observations and histopathology at different intervals were done to evaluate healing. It was concluded that the seeded foetal osteoblasts in the composite grafts augment regeneration of the new bone leading to better integration of graft in host in comparison to bovine acellular cancellous bone matrix graft.

Published: June 2020

Twenty five diverse pumpkin germplasm from North East India were assesed for correlation and path coefficient analysis. Correlation revealed that, characters like number of fruit per plant had significant positive correlation with fruit yield per plant both at genotypic and phenotypic level. Path Coefficient Analysis revealed that, days to first pistillate flower anthesis (1.185) and number of fruits per plant (0.681) had maximum positive direct effect on fruit yield per plant.These are the real independent characters and have maximum contribution towards fruit yield per plant at genotypic level. Whereas at phenotypic level, fruit yield per plant was imposed by number of fruits per plant (0.664) only. From the overall result, the traits like days to first pistillate flower anthesis and numbers of fruits per plant can be utilize for breeding programme to increase fruit yield per plant in pumpkin.
Assessing Livelihood Vulnerability of Farmers’ in Backward Regions of India
Authors: Singh Surendra
Published: June 2020

Agriculture in Bundelkhand region is highly vulnerable to risks and uncertainties. Marginal and small farmers among all farm groups are most vulnerable to the effects of climatic variability. The impact of extreme weather events and natural resources on which farmers are dependent aggravates their vulnerability. The present study uses field surveyed data and IPCC- vulnerability approach, to assess the livelihood vulnerability status of two districts of Bundelkhand region, India. Data was collected using a multistage sampling technique including 200 households. The study concluded that 90% of farmers perceived (exposed) that Kharif season remained hotter and frequencies of droughts have increased over the last five years. Sample households were also highly sensitive due to lack of basic amenities. The lower adaptive capacity due to agriculture as a sole income source, lack of non-farm employment opportunities, monoculture and income diversification and illiteracy are responsible for livelihood vulnerability in the region. From the policy perspective, water conservation through rainwater harvesting, construction of new ponds and check dams would be a possible solution to the present water crisis in the region.

A field experiment was conducted during kharif season of 2013 at Udaipur (Rajasthan) to find out the effect of nitrogen scheduling and cultivars on yield attributes, yield and soil fertility status after harvest of sorghum. Treatment consisted two cultivars (V1: CSH 16 and V2: CSV 20) and five nitrogen schedules (N1: 50% at sowing as basal + 50% at 30 DAS, N2: 50% at sowing as basal + 25% at 30 DAS + 25% at boot leaf stage, N3: 25% at sowing as basal + 50% at 30 DAS + 25% at boot leaf stage, N4: 25% at sowing as basal + 50% at 30 DAS + 15% at boot leaf stage + 10% at grain filling stage, N5: 25% at sowing as basal + 45% at 30 DAS + 5% foliar spray at 45 DAS + 15 % at boot leaf stage + 10% at grain filling stage) were assigned in a factorial randomized block design. The results revealed that the cultivar CSH 16 recorded significantly higher number of grains per panicle, 1000 grain weight, grain yield (1521 kg/ha), harvest index (13.17) and nitrogen content in plant, whereas significantly higher number of primaries per panicle, stover yield (11141 kg/ha) and available nitrogen in soil were recorded in CSV 20. Application of nitrogen in N2 schedule (50% at sowing as basal + 25% at 30 DAS + 25% at boot-leaf stage) had marked influence on yield attributes, yield and nitrogen content in plant when compared to rest of the nitrogen schedules. Therefore, it was concluded that significantly higher grain yield was recorded in cultivar CSH 16 and N2 schedule of nitrogen application from sorghum.

The peculiarity of India’s pulse production scenario highlighted that although India is the largest producer of pulses in the world, its domestic demand outstrips domestic production and the shortfall is met from imports. India imported nearly 5.6 million tons of pulses worth Rs. 18748 crore during 2017-18. The national demand for pulses is increasing as a consequence of increasing population, increasing vegetarianism, measures adopted to tackle the problem of protein energy malnutrition and this necessitates the concerted efforts to increase the production of pulses. Long-term solution to meet demand for pulses lies in increasing the production of pulses in the country which is indeed a challenge for us to ensure supply of pulses as their cultivation is primarily taken up under rain-fed conditions on marginal and sub-marginal lands and is prone to production losses due to moisture stress. The current production scenario of pulses in India reveals that the domestic supply of pulses is nearly capable of meeting the growing demand of its consumers. About 30 million hectares of land is under pulses, producing about 25 million tons annually during 2017-18. Moreover, the realignment of cropping pattern to relatively less water-intensive crops such as pulses in water-scarce areas will have multitude benefits for all.
An Intersectional Content Analysis of Inclusive Language and Imagery Among Sex Trafficking-Related Services
Authors: Gerassi Lara B. , Skinkis Stephanie
Published: June 2020

The extent to which services are available for and inclusive of diverse survivors of sex trafficking remains understudied. This content analysis in a U.S. Midwestern region designated as a hub explores the availability of sex trafficking-specific organizations and perceived inclusivity of organizations regarding diverse identities (including Lesbian, Gay, Bisexual, Trans, or Queer [LGBTQ]+ and racial/ethnic groups). 186 regional organizations were analyzed, of which only 7 were trafficking specific. Of nontrafficking organizations (n = 179), less than 12% (n = 21) stated that they provided services to individuals who identify as LGBTQ+, 6% (n = 10) included LGBTQ+ symbols/language, 36% (n = 65) featured perceived People of Color (POC). Lack of inclusive language, photos, and symbols may contribute to trafficking survivors who identify as POC, English language learners, or as LGBTQ+ feeling as though services do not apply to them. Implications are discussed.

Large gaps exist in our knowledge about the effectiveness of sex trafficking training. This study surveyed knowledge and training regarding sex trafficking among service providers (N = 66; i.e., social workers, law enforcement offers, and medical providers) in one Midwestern state. The study aimed to: (a) determine the goodness-of-fit between respondents' agency criteria for victim identification and established trafficking definitions, (b) assess training desired and received, and (c) examine group differences in knowledge and training by profession and position. Results suggest confusion exists in defining sex trafficking among aftercare providers despite nearly all respondents indicating they had received training on definition, identification, and vulnerability. Training gaps regarding service coordination, case development, and the legal, mental health, and medical needs of victims remain.

Research demonstrates a growing number of exploited and trafficked children in the United States, but few studies address how practitioners continue to respond to these issues. Multiple efforts identify victims of human trafficking and provide services since the passing of the Trafficking Victims Protection Act (TVPA) in 2000 and its reauthorization. However, the TVPA oftentimes failed to protect the most vulnerable. This qualitative study included four focus group sessions with 28 practitioners from various disciplines (e.g., social work, healthcare, legal) to examine how the state of Connecticut has expanded services and programs for children and youth trafficking victims. The findings describe current statewide partnerships along with challenges and successes when working with child victims of human trafficking, offering practice and policy recommendations.
O atuacao da Comissao Brasileiro-Americana de Educacao Industrial na formacao de trabalhadores no Brasil (1946-1962)
Authors: Bordignon Talita Francieli
Published: June 2020

Sob o ponto de vista do materialismo histórico e dialético, o presente artigo busca analisar o protagonismo da Comissão Brasileiro Americana de Educação Industrial (CBAI) entre 1946 e 1962, em suas ações de promoção da hegemonia burguesa. Tomando como fonte histórica o Boletim da CBAI, observa-se a ampliação do Estado na interpenetração entre público e privado. A burguesia brasileira movimentou seus intelectuais orgânicos e os empenhou na solidificação do liberalismo, de modo que a inculcação do american way of life fosse guiada pelo americanismo e o fordismo, como na análise de Gramsci. O escolanovismo na educação técnica industrial foi a estratégia que os donos do poder usaram para operar a manutenção da ordem liberal burguesa. O princípio da unificação diferenciadora foi divulgado nestas escolas para entranhar estes pressupostos na mentalidade dos trabalhadores, a fim de manter a sociedade organizada em classes antagônicas.
