Abstract:

Perovskite quantum dots (PQDs) have the potential to increase the performance of the perovskite solar cell (PSCs). The integration of PQDs into PSCs can extend the absorption range and enhance photon harvesting and device efficiency. In addition, PQDs can stabilize the device structure by passivating surface defects and traps in the perovskite layer and enhance its stability. The integration of PQDs into PSCs is strongly affected by the type of ligands on the surface of PQDs. The ligands affect the charge transport properties of PQDs, as well as the formation of well-defined interfaces and stability of PSCs. In this work, the CsPbBr₃ QDs were synthesized by the conventional hot-injection method using cesium oleate, PbBr₂ and two different ligands, namely oleic acid (OA) oleylamine (OAm) and didodecyldimethylammonium bromide (DDAB). The STEM confirmed regular shape and relatively monodisperse cubic structure with an average size of about 10-14 nm of the prepared CsPbBr₃ QDs. Further, the photoluminescent (PL) properties of the PQDs/perovskite bilayer with the ligand OA, OAm and DDAB were studied. For this purpose, ITO/PQDs as well as ITO/PQDs/MAPI perovskite structures were prepared by spin coating and the effect of the ligand and oxygen plasma treatment was analyzed. The plasma treatment of the PQDs layer could be beneficial for the deposition of the MAPI perovskite layer and the formation of a well-defined PQDs/MAPI interface. The absorption edge in UV-Vis absorption spectra for OA, OAm CsPbBr₃ QDs is placed around 513 nm (the band gap 2.38 eV); for DDAB CsPbBr₃ QDs, it is located at 490 nm (the band gap 2.33 eV). The photoluminescence (PL) spectra of CsPbBr₃ QDs show two peaks located around 514 nm (503 nm) and 718 nm (708 nm) for OA, OAm (DDAB). The peak around 500 nm corresponds to the PL of PQDs, and the peak close to 710 nm belongs to the surface states of PQDs for both types of ligands. These surface states are strongly affected by the O₃ plasma treatment. For PQDs with DDAB ligand, the O₃ exposure (5, 10, 15 s) results in the blue shift of the PQDs peak and a non-monotonous change of the amplitude of the surface states' peak. For OA, OAm ligand, the O₃ exposition did not cause any shift of the PQDs peak, and the intensity of the PL peak related to the surface states is lower by one order of magnitude in comparison with DDAB, being affected by O₃ plasma treatment. The PL results indicate the possibility of tuning the position of the PL maximum by the ligand of the PQDs. Similar behavior of the PQDs layer was observed for the ITO/QDs/MAPI samples, where an additional strong PL peak at 770 nm coming from the perovskite layer was observed; for the sample with PQDs with DDAB ligands, a small blue shift of the perovskite PL maximum was observed independently of the plasma treatment. These results suggest the possibility of affecting the PL maximum position and the surface states of the PQDs by the combination of a suitable ligand and the O₃ plasma treatment.

Abstract:

This paper attempts to indicate the main class dynamics of the Brexit process in a Gramscian theoretical framework. It further aims to point out the influence of the withdrawal of the United Kingdom on the European Union class structure. It defines the unification process of the European Union as a passive revolution. In that way, the Brexit process has been described as a moment of negation in the European Union history of class struggle. It will be argued that the withdrawal of the United Kingdom has already altered the European class structure from the embedded neoliberal structure to a more corporate-liberal one.

Abstract:

This study examined the properties of fresh and hardened concretes as influenced by the moisture state of the coarse recycled concrete aggregates (RCA) after surface treatment. Surface treatment was performed by immersing the coarse RCA in a calcium metasilicate (CM) solution. The treated coarse RCA was maintained in three controlled moisture states, namely, air-dried, oven-dried, and saturated surface-dried (SSD), prior to its use in a concrete mix. The physical properties of coarse RCA were evaluated after surface treatment during the first phase of the experiment to determine the density and the water absorption characteristics of the RCA. The second phase involved the evaluation of the slump, slump loss, density, and compressive strength of the concretes that were prepared with different proportions of natural and treated coarse RCA. Controlling the moisture state of the coarse RCA after surface treatment was found to significantly influence the properties of the fresh and hardened concretes.

Abstract:

The development of American radio and print media since World War II has allowed people with disabilities to engage more directly with the public, gradually changing the perception that disabled people constitute a kind of social impairment or burden. People with disabilities have rarely been portrayed as equal to the non-disabled. In the postwar period, a dramatic shift from eugenicist conceptualizations of disability and widespread institutionalization gradually evolved into conditions of greater openness in public discourse. This discourse was marked at mid-century by telethons and news media (both print and television) which sought to commodify people with disabilities for commercial gain through stories that promoted alienating forms of empowerment alternating with paternalistic pity. By comparing studies of the history of American disability advocacy in the twentieth century and the evolution of the image of disability characteristic of mid-century media discourse, this paper will examine the relationship between the passage of the American with Disabilities Act of 1990 (ADA) and the expanded media representation of people with disabilities. This paper will argue that the legal mandate of the ADA ultimately transformed the image of people with disabilities from those who are weak and in need of support to viable consumers, encouraging traditional American print, film, and television media outlets to solicit the agency of people with disabilities in the authentic portrayal of themselves and their disabilities.

Abstract:

Trademark examination and approval is a complex process that involves analysis and review of the design components of the marks such as the visual representation as well as the textual data associated with marks such as marks' description. Currently, the process of identifying marks with similar visual representation is done manually in United States Patent and Trademark Office (USPTO) and takes a considerable amount of time. Moreover, the accuracy of these searches depends heavily on the experts determining the trademark design codes used to catalog the visual design codes in the mark. In this study, we explore several methods to automate trademark design code classification. Based on recent successes of convolutional neural networks in image classification, we have used several different convolutional neural networks such as Google’s Inception v3, Inception-ResNet-v2, and Xception net. The study also looks into other techniques to augment the results from CNNs such as using Open Source Computer Vision Library (OpenCV) to pre-process the images. This paper reports the results of the various models trained on year of annotated trademark images.

Abstract:

Background: Preterm births of less than 37 weeks gestation occur disproportionately to Hispanics living along the U.S.-Mexico border. Prematurity has devastating and costly effects on children, families and the health care system. Few preventive interventions have been tested for this vulnerable group. Objectives: To present the modeling and pilot testing of the theory-based Mastery Lifestyle Intervention (MLI), designed to reduce and prevent PTB among Mexican American women (the terms Hispanics or Latinas will also be used to represent this group) living in the United States. Design and Methods: The conceptualization of the problem of preterm births and the available literature underpinning the mastery lifestyle intervention will be reviewed. The lifestyle intervention includes foundational components of problem solving therapy and acceptance and commitment therapy. Findings from implementation of a one-group pilot test and focus group evaluated the feasibility and acceptability of the MLI. Summary: Participants found the MLI to be feasible and acceptable, and reported perceiving improved health status and familial relationships. Suggestions were provided for modifications prior to efficacy testing. The MLI appears to be a theoretically and empirically grounded intervention that holds promise for preventing preterm births among Latinas.

Abstract:

The Brazilian Federal Constitution from 1988 innovated with decentralized management, sharing the decision process among the federal government, states, and municipality (federalism). This innovation gave the opportunity to the civil society participates in the public policy agenda, including the municipal one; the state recognized that new actors were needed now it has been one more actor and not the only one. It was in this context that the woman’s Policy Secretaries were created in the three levels of government: federal, state and municipal. It intend to reduce the historical and social differences between men and women, especially in the poorest municipalities, working in a network basis with other secretaries, governmental institutions and non-governmental organizations to promote actions that can result in benefits and empowerment for women. In addition, they promote actions to protect them from domestic violence and to help them to learn how generate income. It was not a calm process, women have been fighting for their rights since the 1970s and despite the gender equality was recognized in the Federal Constitution of 1988, just in 2013 it was possible to see a real growth in the creation of municipal Women’s Policy Secretary. In 2009, just 6.5% of the cities in Brazil had implemented the Secretary; in 2013, it was 11%. The municipality realized that the gender issue was in reality a public problem, so the municipal agenda incorporated it and transformed in public policy, creating the municipal Women’s Policy Secretary. The introduction of a gender policy in Brazilian municipalities shows us that the female citizens are treated as political subjects and it is the first step to try to compensate inequality between men and women in the local level. It becomes more important when the Brazilian federalism is analyzed. In Brazil, the federal government controls the municipalities’ budgets to implement federal public policies and others federal interests, so having a public policy of gender approved by the actors in the local government with so little freedom to manage is something very important. It is necessary mark some points: taking a gender policy to the poorest cities is a form to protect all citizens with no distinction, men and women, as recommended in the Federal Constitution; not all problems in a city center in the municipal agenda, this only happens when a problem is perceived as an issue, it means the women situation was perceived as important, so that it became a public policy; at least, the gender public policy intend to emancipate and contemplate the empowerment of women.

Abstract:

Transportation safety is a major concern for vehicle electrification on a large-scale. The failure cost of lithium-ion batteries is substantial and is significantly impacted by higher liability and replacement cost. With continuous advancement on the material front in terms of higher energy density, upgrading safety characteristics are becoming more crucial for broader integration of lithium-ion batteries. Understanding and impeding thermal runaway is the prime issue for battery safety researchers. In this study, a comprehensive comparison of thermal runaway mechanisms for two different cathode types, Li(Ni₀.₃Co₀.₃Mn₀.₃)O₂ and Li(Ni₀.₈Co₀.₁₅Al₀.₀₅)O₂ is explored. Both the chemistries were studied for different states of charge, and the various abuse scenarios that lead to thermal runaway is investigated. Abuse tests include mechanical abuse, electrical abuse, and thermal abuse. Batteries undergo thermal runaway due to a series of combustible reactions taking place internally; this is observed as multiple jets of flame reaching temperatures of the order of 1000ºC. The physicochemical characterisation was performed on cells, prior to and after abuse. Battery’s state of charge and chemistry have a significant effect on the flame temperature profiles which is otherwise quantified as heat released. Majority of the failures during transportation is due to these external short circuit. Finally, a mitigation approach is proposed to impede the thermal runaway hazard. Transporting lithium-ion batteries under low states of charge is proposed as a way forward. Batteries at low states of charge have demonstrated minimal heat release under thermal runaway reducing the risk of secondary hazards such as thermal runaway propagation.

Abstract:

The significance of high consequence, workplace failures within construction continues to resonate with a combined average of 12 fatal incidents occurring daily throughout Australia, the United Kingdom, and the United States. Within the Australian construction domain, more than 35 serious, compensable injury incidents are reported daily. These alarming figures, in conjunction with the continued occurrence of fatal and serious, occupational injury incidents globally suggest existing approaches to incident analysis may not be achieving required injury prevention outcomes. One reason may be that, incident analysis methods used in construction have not kept pace with advances in the field of safety science and are not uncovering the full range system-wide contributory factors that are required to achieve optimal levels of construction safety performance. Another reason underpinning this global issue may also be the absence of information surrounding the construction operating and project delivery system. For example, it is not clear who shares the responsibility for construction safety in different contexts. To respond to this issue, to the author’s best knowledge, a first of its kind, control structure model of the construction industry is presented and then used to analyse a fatal construction incident. The model was developed by applying and extending the Systems Theoretic and Incident Model and Process method to hierarchically represent the actors, constraints, feedback mechanisms, and relationships that are involved in managing construction safety performance. The Causal Analysis based on Systems Theory (CAST) method was then used to identify the control and feedback failures involved in the fatal incident. The conclusions from the Coronial investigation into the event are compared with the findings stemming from the CAST analysis. The CAST analysis highlighted additional issues across the construction system that were not identified in the coroner’s recommendations, suggested there is a potential benefit in applying a systems theory approach to incident analysis in construction. The findings demonstrate the utility applying systems theory-based methods to the analysis of construction incidents. Specifically, this study shows the utility of the construction control structure and the potential benefits for project leaders, construction entities, regulators, and construction clients in controlling construction performance.

Abstract:

17 Sustainable Development Goals were adopted by the world leaders in September 2015 at the United Nations Sustainable Development Summit. These goals were adopted by UN member states to promote prosperity, health and human rights while protecting the planet. Around the same time, the Government of India launched the Smart City Initiative to speed up development of state of the art infrastructure and services in 100 cities with a focus on sustainable and inclusive development. These cities are meant to become role models for other cities in India and promote sustainable regional development. This paper examines goals set under the Smart City Initiative and evaluates them in terms of the Sustainable Development Goals, using case studies of selected Smart Cities in India. The study concludes that most Smart City projects at present actually consist of individual solutions to individual problems identified in a community rather than comprehensive models for complex issues in cities across India. Systematic, logical and comparative analysis of important literature and data has been done, collected from government sources, government papers, research papers by various experts on the topic, and results from some online surveys. Case studies have been used for a graphical analysis highlighting the issues of migration, ecology, economy and social equity in these Smart Cities.

Abstract:

Mangrove ecosystems in Cameroon are valuable both in services and functions as they play host to carbon sinks, fishery breeding grounds and natural coastal barriers against storms. In addition to the globally important biodiversity that they contain, they also contribute to local livelihoods. Despite these appraisals, a reduction of about 30 % over a 25 years period due to anthropogenic and natural actions has been recorded. The key drivers influencing mangrove change include population growth, climate change, economic and political trends and upstream habitat use. Reversing the trend of mangrove loss and growing vulnerability of coastal peoples requires a real commitment by the government to develop and implement robust level policies. It has been observed in Cameroon that special ecosystems like mangroves are insufficiently addressed by forestry and/or environment programs. Given these facts, the Food Agriculture Organization (FAO) in partnership with the Government of Cameroon and other development actors have put in place the project for sustainable community-based management and conservation of mangrove ecosystems in Cameroon. The aim is to address two issues notably the present weak institutional and legal framework for mangrove management, and the unrestricted and unsustainable harvesting of mangrove resources. Civil society organizations like the Cameroon Wildlife Conservation Society, Cameroon Ecology and Organization for the Environment and Development have been working to reduce the deforestation and degradation trend of Cameroon mangroves and also bringing the mangrove agenda to the fore in national and international arenas. Following a desktop approach, we found out that in situ and ex situ initiatives on mangrove management and conservation exist on propagation of improved fish smoke ovens to reduce fuel wood consumption, mangrove forest regeneration, shrimps farming and mangrove protected areas management. The evidence generated from the field experiences are inputs for processes of improving the legal and institutional framework for mangrove management in Cameroon, such as the elaboration of norms for mangroves management engaged by the government.

Abstract:

The purpose of this case study was to examine beginning music teachers’ perspectives of cultural relevance in relation to music instruction in urban school settings within a large Southwestern city. Research questions focused on the role of student culture in beginning music teachers’ instruction. Data were collected based on Seidman’s (2013) three interview series, consisting of audio recordings from two semi-structured individual interviews for each participant, a 15-20-minute video recording from each participant teaching in their classroom, and an audio recording of one focus group interview. Participants included three beginning music teachers currently employed in urban schools in a major metropolitan city in the Southern United States. In this study, a teacher was considered a beginning teacher if they had zero to three years of experience teaching music in urban school settings. The results revealed three broad themes related to connectivity and relatability, concerts, and differentiated instruction. Implications for current music educators as well as music teacher educators in higher education are included in this study. Further research should consider examining the effect of culturally relevant pedagogy on student retention in urban school music programs.

Abstract:

Undergraduate students, particularly in the environmental sciences, have difficulty displaying quantitative skills in their laboratory courses. Students spend time sampling in the field, often using new methods, and are expected to make sense of the data they collect. Computational thinking may be used to navigate these new experiences. We developed a curriculum for the marine science department at a small liberal arts college in the Northeastern United States based on previous computational thinking frameworks. This curriculum incorporates marine science data sets with specific objectives and topics selected by the faculty at the College. The curriculum was distributed to all students enrolled in introductory marine science classes as a mandatory module. Two pre-tests and post-tests will be used to quantitatively assess student progress on both content-based and computational principles. Student artifacts are being collected with each lesson to be coded for content-specific and computational-specific items in qualitative assessment. There is an overall gap in marine science education research, especially curricula that focus on computational thinking and associated quantitative assessment. The curricula itself, the assessments, and our results may be modified and applied to other environmental science courses due to the nature of the inquiry-based laboratory components that use quantitative skills to understand nature.

Abstract:

The primary focus of this study is to answer “What is the role of corporate governance in corporate failures? Does poor corporate governance lead to corporate failures? If so, how?”. In doing so, the study examines the literature from multiple fields, including corporate governance, corporate failures and organizational decision making, and presents a research gap to analyze and explore the relationship between corporate governance practices and corporate failures through a behavioral lens. In approaching this, a qualitative research methodology is adopted to analyze the failure of Enron Corporation (United States). The research considered the case study organizations as the primary unit of analysis and the decision-makers as the secondary unit of analysis. Based on this research approach, the study reports the analytical results drawn from extensive and triangulated secondary data. The study then interprets the results in the context of the theoretical synthesis. The study contributes towards filling a gap in the research and presents a behaviourally plausible decision centered model of the role of corporate governance in corporate failures. The model highlights the critical role of the behavioral aspects of corporate governance decision making in corporate failures and focuses attention on the under-explored aspects of corporate governance decision making. The study also suggests a further understanding of ‘A Behavioral Theory of the Firm’ in relation to corporate failures.

Abstract:

Structural, electronic, and magnetic properties of Co and Mn-doped CdTe have been studied by employing the full potential linear augmented plane waves (FP-LAPW) method within the spin-polarized density functional theory (DFT). The electronic exchange-correlation energy is described by generalized gradient approximation (GGA) as exchange–correlation (XC) potential. We have calculated the lattice parameters, bulk modulii and the first pressure derivatives of the bulk modulii, spin-polarized band structures, and total and local densities of states. The value of calculated magnetic moment per Co and Mn impurity atoms is found to be 2.21 µB for CdCoTe and 3.20 µB for CdMnTe. The calculated densities of states presented in this study identify the half-metallic of Co and Mn-doped CdTe.

Abstract:

India is the country that shelters the largest number of poor. One of the major areas of concern in India is the unsatisfactory situation of the poor in social developmental and health parameters, not only in rural areas which are partly devoid of the facilities but also in the urban areas where the facilities are insufficient to provide services of a satisfactory quality. Objectives: 1) to examine the association between the environmental condition and health condition among poor women in urban areas. 2) to find out the significance of the effect of environment on the child health among the poor children. 3) to present the scenario of poor among highly urbanized and less urbanized states with respect to the health and environment. Data: data from National Family Health survey-3 and census are used to fulfill the objectives. Methodology: In this study, the standard of living condition of people living in urban areas is computed by taking some household characteristics and assets. People possessing low standard of living are considered as poor. Bivariate and multivariate analysis are employed to examine the effect of environment on poor women and children. A geographical information system is used to present the health and environmental condition of poor in highly and less urbanized states. Results: The findings reveal that the poor women who are not accessed to improved source of water, and sanitation facility are facing more health problems. Children who are living in a dirty environment and are not accessed to improved source of drinking water, among them prevalence of diarrhea and fever is found to be high. As well, the health condition of poor in highly urbanized states is dreadful. Policy implications: Government should emphasize on the implementation of programs regarding the improvement in the infrastructural facilities and health care treatment of urban poor.

Abstract:

Democracy as practiced across the globe is sustained with the increase participation of all eligible voters irrespective of class, race, colour, and disabilities. However, there is a perception within the contemporary African society that people with disability (PWDs) belongs to charity and welfare. This is exacerbated with little understanding among African counties including Nigeria that persons with disability have fundamental rights inevitably rooted in the constitution. This significant viewpoint has continued to militate against the social inclusion of persons with disabilities in various aspects of societal lives including their political participation It is instructive to note that the political right of PWDs has been protected by various international conventions. Article 29 of the United Nations Convention on the Rights and Dignities for Persons with Disability (CRPD) guaranteed the participation of persons with disability in the political process. Domesticating and ratification of this right has been a challenge for many African countries including Nigeria. Against the backdrop, the Independent National Electoral Commission (INEC), the body saddled with the responsibility of conducting elections in Nigeria provided forum for the participation of persons with disability in election through implementations of electoral act. Section 56 (1) and (2) of the 2010 Electoral Act (as amended) provide for voting participation of persons with disability. This study examines the implementation of the electoral act and how it impacts the voting participation of persons with disability vis-à-vis other challenges affecting the participation of PWDs in electoral process in Nigeria’s 2019 general election. This paper draws on mixed method in sourcing relevant information from the respondents. Interview will be conducted among INEC officials, Civil Society Organisations, Joint National Association of Persons with Disability (JONAPWD). Questionnaire and Focus Group Discussion will be held among different forms of PWDs. The data will be analysed using appropriate descriptive statistics and inferential statistics, as well as thematic content analysis. The study will enlighten understanding on the awareness of the political rights of PWDs as well as improving their electoral participation for sustainable democracy in Nigeria, Africa’s most populous country.

Abstract:

In this study, the Functional Theory of Political Campaign Discourse has been applied in order to investigate the 2016 Clinton-Trump presidential debates. All three kinds of utterances (acclaims, attacks, and defenses) were produced by the candidates supporting the usefulness of the Functional Theory of Political Campaign Discourse for the analysis of the presidential debates as a type of political discourse. Attacks comprised 45% of the candidates’ utterances, followed by acclaims at 33%; defenses were the least common function at 22%. The candidate from the Democratic Party, Hillary Clinton, acclaimed more, whereas the Republican Party presidential candidate, Donald Trump, attacked more. Simple denial was the most common form of defense used by the candidates. Both candidates directed more of their utterances to policy (past deeds, future plans, and general goals) than character (personal qualities, leadership abilities, and ideals). Analyzing debates in terms of the functions performed by the candidates to increase their desirability and chance of winning the election, can lead to a better understanding of these significant political events as well as other forms of political discourse.

Abstract:

Honey and honey trade is an important economic activity for many tropical rural and urban areas worldwide. In West Africa and other part of the world, honey and honey products holds high socio–cultural, religious, medicinal, and traditional values. Therefore, to maximize benefits or to enhance profit, a variety of components are added to the raw, fresh and unprocessed honey, introducing the possibility of heavy metals contaminants. Therefore the honey sold in various places, markets and shops in some states in Northern Nigeria (Benue, Nassarawa and Taraba) including Abuja FCT, in Nigeria was analyzed to determine the level of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn). All the honey samples contain heavy metals. The results ranged from 0.028–0.070, 0.023–0.058, 0.042–0.092, 4.231–8.589, 8.115–14.892, 0.078–0.922, 0.044–0.092, 0.041–0.087 and 18.234–28.654 μg/L for Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn respectively. The mean concentration (μg/L) of the heavy metals Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn of the regularly marketed honey is significantly higher than the mean concentration observed in raw, fresh and unprocessed honey.

Abstract:

Australia and Singapore signed the Comprehensive Strategic Partnership (CSP) agreement on 29th June 2015. This agreement aims to strengthen security, defense, diplomatic, economic, education, and innovation cooperation, as well as people-to-people relations between the two states. The purpose of this study is to examine rationales underpinning the (2015 CSP) agreement in order to better understand the national and foreign policy priorities of both Australia and Singapore in the period leading up to the signing of the agreement and in the period since. This research project will seek to establish how both countries’ national and foreign policy priorities have developed in recent years in the light of growing tensions between China and the US in the Indo-Pacific region and how the CSP agreement has influenced these priorities. This project also seeks to better understand and analyse why both states signed the CSP agreement in 2015.

Abstract:

This study explores the relationship between national spending on the Medicaid program, and total Medicaid spending and enrollment in Montana, a state that ranks thirty-third in per capita income and thirty-seventh in median household income in the United States. The purpose of the research is to estimate the potential effects that specific changes to national healthcare policy would likely have on funding for the Montana Medicaid Program and enrollees in the program, members of families in poverty whose incomes are low, even though in many cases they have steady jobs. A particular concern is the effect on access to care for children in poverty who tend to be food insecure and, therefore, especially in need of access to health care. The research uses data collected from a variety of government publications, including the Medicaid Financial Management Report, the Medicaid Managed Care Enrollment Report, and the Centers for Medicare and Medicaid Services MSIS State Summaries for fiscal years 2000-2015. These data were examined using econometric analysis, to assess these impacts. The evidence indicates that the changes included in recent congressional legislative initiatives would potentially leave an additional 50,000 to 60,000 Montana residents, five to six percent of the state’s population, in poverty without access to health care. Impacts on children in poverty would potentially be substantial.

Abstract:

We developed purely sonic, musical based, highly customizable EEG neurofeedback environment designed to administer a new neurofeedback training protocol. The training protocol concentrates on improving the ability to switch between several mental states characterized by different levels of arousal, each of them correlated to specific brain wave activity patterns in several specific regions of neocortex. This paper describes the neurofeedback training environment we developed and its specificities, thus can be helpful as a manual to guide other neurofeedback users (both researchers and practitioners) interested in our editable open source program (available to download and usage under CC license). Responses and reaction of first trainees that used our environment are presented in this article. Combination of qualitative methods (thematic analysis of neurophenomenological insights of trainees and post-session semi-structured interviews) and quantitative methods (power spectra analysis of EEG recorded during the training) were employed to obtain a multifaceted view on our new training protocol.

Abstract:

The manipulation of sports competitions is a new type of sports integrity problem. While doping has become an organized, institutionalized struggle, the manipulation of sports competitions is gradually building up. This study aims to describe and understand how the soft Olympic and Paralympic law was gradually built. It also summarizes the legal tools for prevention, detection, and sanction developed by the international Olympic movement. Then, it analyzes the impact of this soft law on the law of the States, in particular in French law. This study is mainly based on an analysis of existing legal literature and non-binding law in the International Olympic and Paralympic movement and on the French National Olympic Committee. Interviews were carried out with experts from the Olympic movement or experts working on combating the manipulation of sports competitions; the answers are also used in this article. The International Olympic Committee has created a supranational legal base to fight against the manipulation of sports competitions. This legal basis must be respected by sports organizations. The Olympic Charter, the Olympic Code of Ethics, the Olympic Movement Code on the prevention of the manipulation of sports competitions, the rules of standards, the basic universal principles, the manuals, the declarations have been published in this perspective. This sports soft law has influences or repercussions in each state. Many states take this new form of integrity problem into account by creating state laws or measures in favor of the fight against sports manipulations. France has so far only a legal basis for manipulation related to betting on sports competitions through the infraction of sports corruption included in the penal code and also created a national platform with various actors to combat this cheating. This legal study highlights the progressive construction of the sports law rules of the Olympic movement in the fight against the manipulation of sports competitions linked to sports betting and their impact on the law of the states.

Abstract:

Intervention is defined as a forcible interference by a state or states with power in the affairs of another state using force or the threat of force. On the other hand, a military intervention is an intervention, specifically used to define an intervention which uses force. With these, the authors realized a lack in the concept of intervention wherein it is an invited one.The authors wrote this paper to introduce a concept of intervention wherein the intervening state is offering assistance to the state in crisis which asked for one. The authors decided to make a contextual description of this phenomenon because of the lack of concepts regarding intervention between the idea of a single state performing a ‘heroic’ role of intervening in the crisis of another state. The problem that the authors would like to address is regarding the lack of availability in the concept of intervention wherein the state in crisis is seeking the assistance of another state. The authors utilized a contextual description approach to the study through the descriptive presentation of the series of events, by utilizing the news articles and news reports published, which happened in Ukraine and Crimea. This concept is further demonstrated through the utilization of a conceptual framework which shows the mutual relationship between the states. From the analysis of the behavior of Russia and its role in the Crimean Crisis 2014, the authors are able to coin the term, 'Caped Intervention' to describe an intervention of a state as a response to the invitation of assistance of a state in crisis in order for them to achieve their goals. This concept entails a mutual relationship between an intervening state and a sate in crisis. The concept of Caped Intervention describes the role of Russia as a Caped State or an intervening state observed through its action towards Crimea. This concept will help in the observation of the behavior of actors or states in events such as this. It will further help in analyzing the actors’ role in intervention by making it possible to classify the intervening acts into another concept.

Abstract:

River is one of important water sources for many activities including industrial and domestic usage such as daily usage, transportation, power supply and recreational activities. However, increasing activities in a river has grown the sources of pollutant enters the water bodies, and degraded the water quality of the river. It becomes a challenge to develop an effective river management to ensure the water sources of the river are well managed and regulated. In Malaysia, several approaches for river management have been implemented such as Integrated River Basin Management (IRBM) program for coordinating the management of resources in a natural environment based on river basin to ensure their sustainability lead by Department of Drainage and Irrigation (DID), Malaysia. Nowadays, Total Maximum Daily Load (TMDL) is one of the best approaches for river management in Malaysia. TMDL implementation is regulated and implemented in the United States. A study on the development of TMDL in Malacca River has been carried out by doing water quality monitoring, the development of water quality model by using Environmental Fluid Dynamic Codes (EFDC), and TMDL implementation plan. The implementation of TMDL will help the stakeholders and regulators to control and improve the water quality of the river. It is one of the good approaches for river management in Malaysia.

Abstract:

The study of the children’s emotional sphere depending on age and psychoneurological state is of great importance for the design of educational programs for children and their social adaptation. Atypical development may be accompanied by violations or specificities of the emotional sphere. To study characteristics of the emotional state reflection in the voice and speech features of children, the perceptual study with the participation of adults and the automatic recognition of speech were conducted. Speech of children with typical development (TD), with Down syndrome (DS), and with autism spectrum disorders (ASD) aged 6-12 years was recorded. To obtain emotional speech in children, model situations were created, including a dialogue between the child and the experimenter containing questions that can cause various emotional states in the child and playing with a standard set of toys. The questions and toys were selected, taking into account the child’s age, developmental characteristics, and speech skills. For the perceptual experiment by adults, test sequences containing speech material of 30 children: TD, DS, and ASD were created. The listeners were 100 adults (age 19.3 ± 2.3 years). The listeners were tasked with determining the children’s emotional state as “comfort – neutral – discomfort” while listening to the test material. Spectrographic analysis of speech signals was conducted. For automatic recognition of the emotional state, 6594 speech files containing speech material of children were prepared. Automatic recognition of three states, “comfort – neutral – discomfort,” was performed using automatically extracted from the set of acoustic features - the Geneva Minimalistic Acoustic Parameter Set (GeMAPS) and the extended Geneva Minimalistic Acoustic Parameter Set (eGeMAPS). The results showed that the emotional state is worse determined by the speech of TD children (comfort – 58% of correct answers, discomfort – 56%). Listeners better recognized discomfort in children with ASD and DS (78% of answers) than comfort (70% and 67%, respectively, for children with DS and ASD). The neutral state is better recognized by the speech of children with ASD (67%) than by the speech of children with DS (52%) and TD children (54%). According to the automatic recognition data using the acoustic feature set GeMAPSv01b, the accuracy of automatic recognition of emotional states for children with ASD is 0.687; children with DS – 0.725; TD children – 0.641. When using the acoustic feature set eGeMAPSv01b, the accuracy of automatic recognition of emotional states for children with ASD is 0.671; children with DS – 0.717; TD children – 0.631. The use of different models showed similar results, with better recognition of emotional states by the speech of children with DS than by the speech of children with ASD. The state of comfort is automatically determined better by the speech of TD children (precision – 0.546) and children with ASD (0.523), discomfort – children with DS (0.504). The data on the specificities of recognition by adults of the children’s emotional state by their speech may be used in recruitment for working with children with atypical development. Automatic recognition data can be used to create alternative communication systems and automatic human-computer interfaces for social-emotional learning.
