La discriminación laboral en razón del género y la edad en Colombia
Authors: Nuvaez Castillo José Javier
Published: May 2019

Recibido: 19 de septiembre del 2018Aprobado: 28 de noviembre del 2018La discriminación o diferenciación laboral se define como un trato diferenciado basado en razones diversas; es el señalamiento prejuicioso a una determinada persona con ciertas características, adjudicándole una condición o sentido de inferioridad. En tal sentido, con fines de análisis se examina este concepto, para indagar su alcance o trascendencia; en un  estudio enmarcado bajo un referente teórico basado en el criterio de expertos en el área. El estudio es una investigación documental con un diseño bibliográfico. Los resultados reflejan una problemática actual, que genera un impacto socio-cultural en Colombia, producido por lo alarmante en los niveles de discriminación en el país, debiendo concluir que en la medida en que se perpetúe este panorama desolador en materia laboral, el trabajo continuará siendo un motivo de frustración y no una fuente de realización personal de los trabajadores colombianos, en razón del rechazo, la exclusión a lo que son sujetos los mismos.
Regionalismo e integración regional: una aproximación teórica
Authors: Murillo Zamora Carlos
Published: May 2019

Los procesos de integración regional han mostrado importantes avances tras el fin de la Guerra Fría, lo que ha generado numerosos estudios desde una perspectiva práctica. Sin embargo, no ha ocurrido lo mismo con la teorización de los elementos y dinámica que caracterizan la construcción de regiones y el regionalismo, que son básicos para entender la integración. A ello se suma la cuestión del viejo y el nuevo regionalismo, que significa un importante avance en la comprensión de los fenómenos que tienen lugar a inicios del Siglo XXI.

Treatment of psychopathic offenders: Evidence, issues, and controversies
Authors: Olver Mark E.
Published: May 2019

Psychopathic offenders are a notoriously challenging population to treat, who are often recalcitrant to change and at high risk for program non-completion and recidivism. The present work is a review and synthesis of the evidence, issues, and controversies in the treatment of psychopathic offenders. The operationalization and measurement of the construct of psychopathy via the Hare Psychopathy Checklist–Revised is reviewed to give context to the population being treated and to identify latent features of the syndrome that have risk and treatment implications. A discussion of the issues and challenges in the treatment of psychopathic offenders is then provided to contextualize the source of therapeutic pessimism with this population, followed by a review of the existing psychopathy treatment literature. The characteristics of unsuccessful and encouraging treatment programs, including a promising model of treatment, are subsequently reviewed, and the article finishes with a synopsis of recent treatment outcome findings published subsequent to previous psychopathy treatment reviews or inadvertently overlooked by past reviews. Although psychopathic offenders are a challenging population to treat, I argue that they are not immune to making positive lifestyle and behavioural changes, and that these individuals have the potential to benefit if they can be retained in treatment.

Survivability factors for Canadian cyclists hit by motor vehicles
Authors: Demers Simon
Published: May 2019

Police-reported data from Transport Canada’s National Collision Database (NCDB) are analyzed with a view to identify and quantify various factors that can impact the survivability of cyclists involved in a motor vehicle collision. A Least Absolute Shrinkage and Selection Operator (LASSO) regression and a multiple imputation (MI) process address the variable selection and missing data problems, respectively. The resulting probabilistic model suggests that collision sur-vivability depends largely on the cyclist’s age and helmet usage. Survivability improves with age up to age 21, peaks for cyclists aged 21 to 34, and falls after age 35. Controlling for age and other factors, a bicycle helmet reduces the risk that a cyclist fatality will occur by approximately 34% (OR: 0.66, 95% CI: 0.56-0.78). Survivability in general, and the apparent safety benefits of bicycle helmets in particular, do not appear to depend on the sex of the cyclist once the type of collision and other factors are controlled for. Head-on and rear-end collisions tend to be more deadly. Certain environmental and situational variables, like strong winds and traffic control devices, also appear to impact survivability. There might be opportunities to sensitize cyclists of various age groups about the risks they are exposed to while cycling, and prevent or better protect cyclists from head-on and rear-end collisions.

A strategic approach to police interactions with people with a mental illness
Authors: Coleman Terry G. , Cotton Dorothy
Published: May 2019

Since the birth of modern policing in the early 1800s, police agencies have interacted with persons with mental health problems (P/MHP) whether in crisis, as victims, or in a support role. Given the nature of policing, this is unlikely to change. What has changed is how police handle these situations. This paper identifies and explains the two phases of the evolution, to date, of police responses and the now necessary third phase. It is time for police agencies to apply a focussed corporate approach to this important social issue and to establish a mental health strategy (third generation) in order to clearly take a strategic approach in concert with relevant community agencies to improve outcomes for P/MHP who come into contact with police personnel. While many standalone programs have been primarily reactive, this paper makes the case that a strategic approach enables the design and implementation of multiple programs congruent with the mental health strategy that are proactive as well as reactive, all with the aim of improving the outcomes for persons with mental illness and mental health problems.

Published: May 2019

Illicit drug overdose is a public health issue that leads to significant morbidity and mortality. In order to reduce the harm associated with substance use, emergent issues related to substances and substance use must be addressed in a timely manner, which requires inter-sectoral collaboration. We describe the British Columbia Drug Overdose and Alert Partnership, an innovative collaborative model of stakeholders who work in prevention, harm reduction, treatment and enforcement related to psychoactive substance use. We describe the formation, purpose, stakeholders, and operation of the partnership and resultant public health surveillance system. We use the example of fentanyl-associated overdoses and deaths to describe the attributes that make the system effective. These include timeliness, flexibility, acceptability and costs. This model of inter-sectoral collaboration and surveillance can be applied to other organizations involved in assessing and responding to drug-related harms.
Christian Ethics on Divorce
Authors: Lagat Daniel
Published: May 2019

The institution of marriage, originally started and blessed by God, is facing the threat of desacralization, disrepute, and collapse. Divorce is now emerging as the leading intervention to marital conflicts. A greater concern however is that among the people that choose divorce and remarriage are Christian leaders and clergymen and clergywomen. Their decision on accepting divorce is based on their understanding that Jesus and Paul gave some reasons and excuses why and how someone would take divorce and remarriage as a choice. This paper argues that the biggest factor at play, is the worldviews that people have on marriage, something which guides judgement, and determine options that someone takes when they are faced with extended family row. The people that hold the “I need you” or ‘you needed me’ mindset, would either choose divorce as the only option, or decided to endure the partners. This paper argues that both of these are ramification of entering marriage with unstable worldview. The people that enter marriage with the ‘I was wanting, I am made whole by you’ mindset, are likely to view extended marriage row as something positive, and pray for God to help them overcome the trial, in order to come out victorious.
Savings and Credit Cooperative Societies (SACCOs)in Kenya
Authors: Kabaiku Peter Mwaura
Published: May 2019

The article seeks to retrace the historicity of Savings and Credit Cooperative Societies (SACCOs) in Kenya with the view to establishing its theo-social justification. Put it differently, beyond economic development, can we socially justify it? Can SACCOs be justified theologically and philosophically? The initial specific objectives were; to determine the extent to which all stakeholders in society can play a role in promoting ethics and integrity in the management of community based savings and credit cooperative societies without the feeling that it belongs to ‘other’ people in economic circles, to assess the extent to which ecclesiastical institutions can invest in community based savings and credit cooperative societies, and to investigate its historicity in order to inform the future studies and researches in this area. The findings in this article will be essential in making a theo-social justification for future reference. The researcher validated the research instrument by having the research supervisor go through the questions to identify whether they had construct, content validity and face validity.
‘Radical Focusing’ as the ideal conceptual framework in addressing substance abuse
Authors: Njogu Geoffrey Karimi
Published: May 2019

The article seeks to philosophically introduce “Radical Focusing” as a new concept in fighting drugs among the Kenyan youths and in the rest of the tropical Africa. By “Radical Focusing”, it means, employing the whole armour for combat in our bid to dismantle this destructive trajectory that principally threatens to wipe out the youth, and the boy-child in particular. The concept of radical focusing is largely inspired by Dietrich Bonhoeffer’s concept of the “Costly Grace.” In this concept of the costly grace in Nazi Germany of 1930s, Bonhoeffer fought injustices to the point of his own physical destruction during the era of Adolf Hitler. Owing to the sad scenarios of the day, Bonhoeffer inspired us to fight vices to the very end, and radically focus on the noble agenda throughout. The data in this article has been collected through the use of questionnaires and interview schedule. Questionnaires were administered to the interviewees, most of whom sought anonymity owing to the sensitive nature of research. Apart from the interviews, existing commissions of investigative inquiry on education such as the Ominde commission of 1964 which proposed that the government should take over from churches and eventually manage schools; and Kamunge Commission among others, have provided resourceful information to the research that gave birth to this article. It is hoped that the research findings will go a long way in reconstructing our broken society for the better, and eventually bring remedy for drug abuse to masses of people who have lost direction in this endeavor.
Vision 2030 and the Gender Question in Kenya
Authors: Njagi Catherine Wambui
Published: May 2019

The article sets out to demonstrate the question of gender violence as a critical concern as Kenya seeks to implement her ambitious vision 2030. In other words, how can gender based violence affect the Implementation of Kenya vision 2030? Can it hinder Kenya’s ambitious enterprises in the 21st century? Certainly, Kenya’s Vision 2030 is a long term development blue print that seeks to transform Kenya into a newly industrializing middle income country. In so doing, it aims at providing a high quality life to all its citizens in a clean and secure environment. The plan is anchored on three pillars, economic, social and political governance. The economic pillar aims to achieve an economic growth rate of 10% per annum; and sustaining the same till 2030 in order to generate more resources that will eventually address Kenya’s development goals. In turn, the social pillar seeks to create just, cohesive and equitable social development in a clean and secure environment; and the political pillar seeks to realize an issue based, people centered, result oriented and accountable democratic system. In view of this, Gender Based Violence is an umbrella term for any harmful act that is perpetrated against a person’s will and which is based on socially ascribed (gender) differences between men and women. Gender-based Violence (GBV) describes the specific type of violence that is linked to the gendered identity of being a woman or man. Gender based Violence traumatizes men, women and children. It destroys careers, and hurts the national economies among other negative effects. The main objective of this article is to show the link between Gender Based Violence and Kenya vision 2030. Methodologically, it starts by summarizing the vision 2030 highlighting its major strategies like education and training, health sector, Equity and poverty reduction, environment management, tourism, water and sanitation, electoral and political processes, democracy and public service, gender and youth among others and major flagship projects like Konza Techno city, expansion of port of Mombasa, the building of standard gauge railway, modernization of Jomo Kenyatta airport, expansion of Lamu port among others. Using the society of International development report and other organizations who have constantly audited the implementation of the vision 2030 since it began in 2008, the article will show how gender based violence will slow the achievement of the vision 2030. It will also show how reducing gender based violence would help in its achievement. The materials in this article have been methodologically gathered through participant observation, reading of relevant literature, field research conducted in 2015 and sampling the city of Nairobi which largely speaks for Kenya and the larger East Africa.
Traditional Understanding of Grief Among Ameruin Kenya

Published: May 2019

The main objective of this article isto explore the Ameru indigenous ways of overcoming death and grief. Death and grief have always been the most challenging thing throughout the history of humanbeings, and even withincontemporarysociety. The Ameru culture provided room, space and meaning of death and life after death to both the dead and to the living. The culture was an integral part of Ameru, especially on matters of death and grief. The culture provided values found to be helpful to the well-being of the Ameru people, in a holistic way especially in the period of grief and bereavement. The article explores these meaning and how they can be relevant to the contemporary society, which ethos are guided by the Church. Today, the church plays the central role in overcoming grief and bereavement. In meaning making, there is a needfor contextualization.Contextualization is an attempt to present the gospel in culturally relevant ways. For this reason, this article triesto explore some of the Ameruways of overcoming grief and how this can be relevant to the contemporary Church diakonia work and counseling of grief.
“Mwendoni-ire ZK”
Authors: Gathogo Julius , Gitumu Margaret W.
Published: May 2019

In this article, Professor ZK Mathews is not only seen as a responsible leader in his own right but more importantly, he is seen as a prominent educationist in the complex socio-political situation of apartheid South Africa. “Mwendoni-ire Z K” (beloved ZK) became the first African to obtain a Bachelor of Arts Degree (BA) at the University of South Africa, in 1924. His other public roles as ANC founder, Ambassador, an educationist, activist for social justice, a Pan-Africanist, and an ecumenist makes him one of a kind. As both a community and church leader, the article seeks to assess his display of social responsibility in the dark period of African history when separate development was the vogue. Did he act responsibly in addressing social issues during his heydays? What didn’t he do during his lifetimes? Are there critical communal issues that he failed to do yet he had an opportunity which he did not exhaustively utilize? To this end, this article builds on the premise that the spread of Christianity in Africa, its shape and character, has been the by-product of responsible Leadership, both in the Mission Churches/mainline churches and in the African Instituted Churches, and even from within the emerging afro-Pentecostal churches. Without responsible leadership on the part of the Africans themselves, the spread of Christianity in Africa would have nose-dived. In categorising the three brands of Christianity in Africa, it is critical to acknowledge that, Mission Churches are those that evolved directly from the outreach of Western denominations; afro-Pentecostals are those who consciously or unconsciously allow a measure of dialogue between Pentecostalism and some elements of African culture in their discourses; while African initiated Churches are those Churches which were born in Africa, and were primarily begun by Africans themselves as they protested western intrusion and subjugation of their cultures as Africans. In view of this, ZK is viewed as a responsible leader who confronted social ecclesial matters with a reasonable degree of success.
H i Clouds in LITTLE THINGS Dwarf Irregular Galaxies
Authors: Hunter Deidre A. , Elmegreen Bruce G. , Berger Clara L.
Published: May 2019

We identify 814 discrete H i clouds in 40 dwarf irregular galaxies from the LITTLE THINGS survey using an automated cloud-finding algorithm. The cloud masses range from ∼103 to 107
M
⊙, have a surface density averaged over all of the clouds of ∼9.65 M
⊙ pc−2, and constitute 2%–53% of the total H i mass of the host galaxy. For individual clouds, the mass including He varies with cloud radius as

 × 

and the internal velocity dispersion varies as

 × 

. The H i clouds tend to be in the outer regions of the galaxies, with 72% of the galaxies having more than 70% of their clouds outside one disk scale length and 32% of the galaxies having more than 50% of their clouds outside the radius encircling the H ii emission. Thirty-six percent of the clouds are essentially non-self-gravitating from H i alone, with a virial parameter that exceeds α
vir ∼ 10, and 5% have α
vir ≤ 2. We estimate the missing molecular mass, based on the total star formation rate and a typical molecular consumption time of 2 Gyr, as observed in CO-rich galaxies. The resulting molecular fraction has a value averaged over the galaxies of 0.23 and correlates with both the surface density of star formation and the fraction of H i clouds in the outer regions. We conclude that a significant fraction of the inner parts of these dwarf galaxy disks is in the form of dark molecular gas, and that this fraction could be high enough to make the inner disks mildly gravitationally unstable as a precursor to star formation.
An Upper Limit on Primordial Magnetic Fields from Ultra-faint Dwarf Galaxies
Authors: Safarzadeh Mohammadtaher , Loeb Abraham
Published: May 2019

The presence of primordial magnetic fields increases the minimum halo mass in which star formation is possible at high redshifts. Estimates of the dynamical mass of ultra-faint dwarf galaxies (UFDs) within their half-light radius constrain their virialized halo mass before their infall into the Milky Way. The inferred halo mass and formation redshift of the UFDs place upper bounds on the primordial comoving magnetic field, B
0. We derive an upper limit of 0.50 ± 0.086 (0.31 ± 0.04) nG on B
0 assuming the average formation redshift of the UFD host halos is z
form = 10 (20), respectively.
Multi-decadal surveys in a Mediterranean forest reserve – do succession and isolation drive moth species richness?
Authors: Wölfling Mirko , Uhl Britta , Fiedler Konrad
Published: May 2019

Isolated fragments of semi-natural habitats are often embedded in a landscape matrix that is hostile to organisms of conservation concern. Such habitat islands are prone to changes in their biota over time. For insects, few studies on long-term trends in species richness within conservation areas are available, mainly due to the lack of historical data. We here use moths in the coastal pine wood reserve Pineta san Vitale (Ravenna, NE Italy) to assess how local fauna has changed over the last 85 years. This reserve has experienced massive changes in vegetation structure due to secondary succession. We compared historical collections (1933–1976: 107 species; and 1977–1996: 157 species) with our own samples (1997–2002: 174 species; and 2011+2012: 187 species). Over the last 85 years, the proportion of habitat generalists in relation to all recorded moth species increased from 20 to 33%. The fractions of woodland and open habitat species concomitantly decreased by 10 percentage points, respectively. Amongst woodland and habitat generalist species, gains outnumbered losses. In contrast, 18 species of open habitats and 10 reed species were lost over the decades. We attribute these changes to vegetation succession and to the isolation of the reserve. Generalist species are presumably better able to pass through anthropogenically exploited landscapes and colonise isolated habitat fragments than habitat specialists.
Water acidification causes death of marine ornamental fish (Perciformes: Pomacentridae) during transport: contributing to the conservation of wild populations
Authors: Sampaio Flavia D.F. , Silva-de-Assis Helena C. , Bettim Franciele L. , Fávaro Luís F. , Freire Carolina A.
Published: May 2019

Pomacentridae is a common family in the aquarium fish trade. Most species are harvested from nature. Here we evaluate the following water parameters in the pomacentrid sergeant major,Abudefdufsaxatilis(Linnaeus, 1758), to assess their stress level during a 24, 48, and 72 hours transport: dissolved oxygen (DO), total ammonia, and pH. In addition, we evaluated the following physiological parameters: plasma osmolality, muscle water content, blood glucose, and the enzyme activities of the branchial carbonic anhydrase (CA), the hepatic glutathione S-transferase (GST), catalase (CAT), and superoxide dismutase (SOD). The mortality of fish measuring >6 cm total length was 22%, while no mortality was observed for fish measuring <6 cm. The pH of the water was significantly correlated with fish mortality, especially for the initial 24 hours of transport. Hypoxia after 24–48 hours also led to fish mortality, but build up ammonia was not a problem even after 72 hours. We suggest that a minimum water volume of 125 ml/g fish is necessary for safe and cost-effective transport of the sergeant major, preferably with <6 cm in total length.
Redesigning and Implementing Traditional Musical Instrument in Integrated Technology Classroom
Authors: Julia J. , Iswara Prana Dwija , Supriyadi Tedi
Published: May 2019

Elementary school students in Indonesia are required to learn to play traditional musical instruments, one of which is angklung (a bamboo musical instrument). However, they might have difficulty in playing angklung because angklung is a type of musical instrument that comes in an ensemble, so it must be played collaboratively. This paper aims at providing a solution for learning to play angklung easily by designing a technology-based touch angklung and implementing it in the classroom. Several computer applications and hardware were integrated to develop the touch angklung. The applications used are Sibelius, Kontakt, Sound Forge Audio Studio, and Scratch. Meanwhile, the hardware used is the MakeyMakey Kit (MMK). The development of the touch angklung comprised of sampling the angklung sounds, making angklung sound buttons on the computer, redesigning the angklung, and assembling the MMK with angklung. The touch angklung was implemented in the classroom in two schools, which consist of 30 students. Each student participated in a survey to identify the results of learning to play traditional musical instruments using the touch angklung. Observations were also carried out by the teachers and researchers. The results showed that the students had high motivation to play the touch angklung. They could play song compositions easily based on the melodies of the songs they have memorized. In conclusion, learning traditional musical instruments is more attractive to students when integrated with technology.
The Value of Network Sustainability
Authors: Ernst Elisabeth
Published: May 2019

This paper develops the concept of network sustainability. To become and stay sustainable, distributed research infrastructures must satisfy present needs while at the same time be flexible and resilient to meet future requirements. With regard to this, it is not enough to merely build a resilient economic model and be technically viable. Research infrastructures that can understand, address and shape future needs to have a sustainable community network. Clear characteristics of a research infrastructure with a sustainable network are that partners gain access to other networks and interest groups, that knowledge, information and expertise is shared freely among partners, that the infrastructure increases partners’ visibilities and vice versa, and that partners are enabled to stay current and state-of-the-art. This is shown on OPERAS (open access in the european research area through scholarly communication), a research infrastructure for open scholarly communication in the social sciences and humanities, and its member the Max Weber Foundation, a German research institution.
Beyond the Dichotomy between Natural and Knowledge Commons
Authors: Albagli Sarita , Clinio Anne , Parra Henrique Z.M. , Fonseca Felipe
Published: May 2019

The paper presents a critical analysis of the possibilities
and limits of the Institutional Analysis and Development (IAD) framework,
proposed by Elinor Ostrom and team, specially addressing the mutual relations
between natural and knowledge commons. It results from an action research
project on the role of open science (OS) in development, carried out in the
municipality of Ubatuba, on the North Coast of the State of São Paulo, Brazil,
in 2015-2017. The work involved: systematizing the literature on the IAD
framework; mapping and selecting literature representative of other theoretical
and conceptual approaches; critically using and adapting the framework to the
case studied. The project provided the opportunity to observe how these dynamics
take place in a relatively small-scale (while heavily interconnected) context.
While the IAD framework helped us to analyze the institutional, political, and
governance issues affecting knowledge production and circulation, we observed
the higher complexity of our action arena, shedding light on the fact that
natural and knowledge commons are the two dimensions of the same “commoning”
process.
RECURRENCE QUANTIFICATION ANALYSIS OF MCI EEG UNDER RESTING AND VISUAL MEMORY TASK CONDITIONS
Authors: Timothy Leena T. , Krishna Bindu M. , Nair Usha
Published: May 2019

The work aims at classifying EEG of mild cognitive impairment (MCI) patients from that of normal control (NC) subjects using recurrence quantification analysis (RQA) and a simple visual memory task, which is commonly used in memory clinics. EEG of MCI and NC groups are recorded under three cognitive conditions, resting eyes closed (EC) and two phases of the task, namely, picture viewing (learning phase, PIC) and picture recollection (immediate free recall phase, PICREC). Complexity analysis of EEG is performed using RQA measures, recurrence rate (RR) and entropy (ENTR). Mean values of these measures over electrodes from four cortical regions are used for statistical analysis of group differences, under the different cognitive conditions. In all the cortical regions, the mean RQA RR and ENTR values of MCI group are observed to be higher compared to NC group under the task conditions. Receiver operating characteristics (ROC) analysis is used for assessing the classification efficiency of the RQA-based method applied to EEG of MCI subjects. A fair classification is obtained in all the four cortical regions during the PIC condition using RR and in all regions except frontal, using ENTR. In the PICREC condition, a good classification is obtained in the temporal, parietal and occipital regions and a fair classification is attained in the frontal region using RR. In this condition, the ENTR values provided a fair classification in all the four cortical regions. These RQA measures are used as feature vectors of SVM classifier to further confirm the classification efficiency of the couplets of RQA RR and ENTR. These results indicate RQA method can efficiently classify MCI EEG based on complexity levels using the simple immediate free recall task.
PROFICIÊNCIA MOTORA EM CRIANÇAS NORMAIS E COM DIFICULDADE DE APRENDIZAGEM: ESTUDO COMPARATIVO E CORRELACIONAL COM BASE NO TESTE DE PROFICIÊNCIA MOTORA DE BRUININKS-OSERETSKY
Authors: Moreira Nilson Roberto , Fonseca Vitor Da , Diniz Alves
Published: May 2019

Neste estudo investigativo sobre crianças com dificuldades de aprendizagem, procurou-se verificar a existência de diferenças com relação às crianças que não apresentavam dificuldades, através da utilização do teste de proficiência motora de Bruininks e Ozeretsky (1978). Participaram desta investigação 30 crianças, sendo 15 do sexo masculino e 15 do sexo feminino, subdivididas em dois grupos de 15 crianças de cada sexo, as normais, freqüentando o 3º ano de escolaridade básica e as portadoras de D.A. freqüentando o 2º ano, portanto com uma repetência. A média de idade considerada foi de 8 anos, pertencentes ao nível socioeconômico médio, segundo a escala de Grafar (adaptada por Fonseca, 1991). Foram excluídas do trabalho crianças que pudessem apresentar qualquer tipo de deficiência, que não a reprova, controlando-se ainda o Fator "G" de inteligência, utilizando um percentil, maior ou igual a 50 (nível médio a superior), medido pelo teste das Matrizes Progressivas de Raven (1974). Em termos de proficiência motora, as crianças com dificuldades de aprendizagem exibem diferenças significativas quando comparadas com crianças normais da mesma idade, em todas as componentes da motricidade global, composta e fina. Os testes aplicados evidenciaram também a existência de forte correlação entre as variáveis das componentes da proficiência motora. Ao final, pode-se concluir, em função dos resultados, existir diferenças significativas na proficiência motora entre crianças normais e crianças com dificuldades de aprendizagem, assinalando nestas últimas dificuldades motoras específicas, refletindo que elas apenas evidenciam um perfil motor mais vulnerável, e não a presença de sinais neurológicos disfuncionais.

Discrete Paraproduct Operators on Variable Hardy Spaces
Authors: Tan Jian
Published: May 2019

Let$p(\cdot ):\mathbb{R}^{n}\rightarrow (0,\infty )$be a variable exponent function satisfying the globally log-Hölder continuous condition. In this paper, we obtain the boundedness of paraproduct operators$\unicode[STIX]{x1D70B}_{b}$on variable Hardy spaces$H^{p(\cdot )}(\mathbb{R}^{n})$, where$b\in \text{BMO}(\mathbb{R}^{n})$. As an application, we show that non-convolution type Calderón–Zygmund operators$T$are bounded on$H^{p(\cdot )}(\mathbb{R}^{n})$if and only if$T^{\ast }1=0$, where$\frac{n}{n+\unicode[STIX]{x1D716}}<\text{ess inf}_{x\in \mathbb{R}^{n}}p\leqslant \text{ess sup}_{x\in \mathbb{R}^{n}}p\leqslant 1$and$\unicode[STIX]{x1D716}$is the regular exponent of kernel of$T$. Our approach relies on the discrete version of Calderón’s reproducing formula, discrete Littlewood–Paley–Stein theory, almost orthogonal estimates, and variable exponents analysis techniques. These results still hold for variable Hardy space on spaces of homogeneous type by using our methods.

Распределение этих величин неизвестно, за исключением того, что заданы достаточно слабые ограничения на предельное поведение вероятностей больших значений степеней. Найдены условия, при выполнении которых граф асимптотически достоверно связан при стремлении числа вершин к бесконечности. Даны оценки скорости сходимости к нулю вероятности того, что граф не связен.
Emotional Contagion and Group Affective Tone in the Student Cohort Model
Authors: Jensen Michael
Published: May 2019

OBJECTIVE. The student cohort model used by most occupational therapy programs can produce outcomes that are either adaptive or maladaptive as a result of the unique identities formed by student cohorts. The purpose of this study was to examine the cohort model through the lens of group-level affect and emotional contagion theory.

METHOD. The study used a cross-sectional survey design with 159 undergraduate health care cohort members (including occupational therapy assistant students) across 24 student cohorts. The survey consisted of three measures, the Positive and Negative Affect Schedule, the Emotional Contagion Scale, and the Emotional Expressivity Scale.

RESULTS. Data analysis showed that group affective convergence occurred along a continuum of positive affect. The results also showed that cohort members’ susceptibility to the emotion of anger strengthened the cohort’s emotional convergence.

CONCLUSION. Cohort identity may be influenced by the process of emotional contagion, creating a distinct group-level affect.
Peacock Revolution
Authors: Hill Daniel Delis
Published: May 2019

The Peacock Revolution in menswear of the 1960s came as a profound shock to much of America. Men’s long hair and vividly colored, sexualized clothes challenged long established traditions of masculine identity. Peacock Revolution is an in-depth study of how radical changes in men’s clothing reflected, and contributed to, the changing ideas of American manhood initiated by a “youthquake” of rebellious baby boomers coming of age in an era of social revolutions.

Featuring a detailed examination of the diverse socio-cultural and socio-political movements of the era, the book examines how those dissents and advocacies influenced the youthquake generation’s choices in dress and ideas of masculinity. Daniel Delis Hill provides a thorough chronicle of the peacock fashions of the time, beginning with the mod looks of the British Invasion in the early 1960s, through the counterculture street styles and the mass-market trends they inspired, and concluding with the dress-for-success menswear revivals of the 1970s Me-Decade.
Citizenship Education in Conflict-Affected Areas
Authors: Akar Bassel
Published: May 2019

Citizenship Education in Conflict-Affected Areas examines the practices of learning and teaching citizenship in Lebanon, and explores the implications of the research findings for those working in other sites affected by conflict.

Bassel Akar analyses rich empirical data, such as semi-structured interviews with teachers and open-ended survey packs with children in classrooms, which reveal conflicts in notions of citizenship and pedagogical approaches. These in-depth explorations of classroom learning and teaching show the hidden and subtle factors that often subvert intentions to promote social cohesion and active citizenship through education. Examining how individual conceptualizations of citizenship influence approaches to learning and teaching and vice versa, the author argues that learning citizenship in schools can undermine aims of democratic participation, dialogue and critical thinking. He concludes and considers why classroom learning of civic education in Lebanon can actually be more harmful than beneficial. Offering new insights for educators and policymakers working beyond the Lebanese context, Citizenship Education in Conflict-Affected Areas is a valuable addition to the research in this growing field.
DETECTING RUMEX OBTUSIFOLIUS WEED PLANTS IN GRASSLANDS FROM UAV RGB IMAGERY USING DEEP LEARNING
Authors: Valente J. , Doldersum M. , Roers C. , Kooistra L.
Published: May 2019

Abstract. Broad-leaved dock (Rumex obtusifolius) is a fast growing and spreading weed and is one of the most common weeds in production grasslands in the Netherlands. The heavy occurrence, fast growth and negative environmental-agricultural impact makes Rumex a species important to control. Current control is done directly in the field by mechanical or chemical actuation methods as soon as the plants are found in situ by the farmer. In nature conservation areas control is much more difficult because spraying is not allowed. This reduces the amount of grass and its quality. Rumex could be rapidly detected using high-resolution RGB images obtained from a UAV and optimize the plant control practices in wide nature conservation areas. In this paper, a novel approach for Rumex detection from orthomosaics obtained using a commercial available quadrotor (DJI Phantom 3 PRO) is proposed. The results obtained shown that Rumex can be detected up to 90% from a 6 mm/pixel ortho-mosaic generated from an aerial survey and using deep learning.
INTRODUCING A FRAMEWORK FOR CONFLATING ROAD NETWORK DATA WITH SEMANTIC WEB TECHNOLOGIES
Authors: Niestroj M. G. , McMeekin D. A. , Helmholz P.
Published: May 2019

Abstract. Road network asset management is a challenging task as many data sources with different road asset location accuracies are available. In Australia and New Zealand transport agencies are investigating into harmonisation of road asset data, whereby two or more data sets are merged to create a new data set. Currently, identifying relations between road assets of the same meaning is not always possible, as road authorities of these countries use their own data structures and standards. This paper employs SemanticWeb Technologies, such as RDF/Turtle ontologies and semantic rules to enable road network conflation (merge multiple data sets without creating a new data set) as a first step towards data harmonisation by means of information exchange, and shifts road network data from intersections and road nodes to data sets considering the accuracy of the data sets in the selected area. The data integration from GeoJSON into RDF/Turtle files is processed with Python. A geographic coordinates shifting algorithm reads unique data entries that have been extracted from RDF/Turtle into JSON-LD and saves the processed data in their origin file format, so that a closed data flow can be approached.
INDOOR 3D MODELING AND FLEXIBLE SPACE SUBDIVISION FROM POINT CLOUDS
Authors: Nikoohemat S. , Diakité A. , Zlatanova S. , Vosselman G.
Published: May 2019

Abstract. Indoor navigation can be a tedious process in a complex and unknown environment. It gets more critical when the first responders try to intervene in a big building after a disaster has occurred. For such cases, an accurate map of the building is among the best supports possible. Unfortunately, such a map is not always available, or generally outdated and imprecise, leading to error prone decisions. Thanks to advances in the laser scanning, accurate 3D maps can be built in relatively small amount of time using all sort of laser scanners (stationary, mobile, drone), although the information they provide is generally an unstructured point cloud. While most of the existing approaches try to extensively process the point cloud in order to produce an accurate architectural model of the scanned building, similar to a Building Information Model (BIM), we have adopted a space-focused approach. This paper presents our framework that starts from point-clouds of complex indoor environments, performs advanced processes to identify the 3D structures critical to navigation and path planning, and provides fine-grained navigation networks that account for obstacles and spatial accessibility of the navigating agents. The method involves generating a volumetric-wall vector model from the point cloud, identifying the obstacles and extracting the navigable 3D spaces. Our work contributes a new approach for space subdivision without the need of using laser scanner positions or viewpoints. Unlike 2D cell decomposition or a binary space partitioning, this work introduces a space enclosure method to deal with 3D space extraction and non-Manhattan World architecture. The results show more than 90% of spaces are correctly extracted. The approach is tested on several real buildings and relies on the latest advances in indoor navigation.
REDUCTION OF THE FRONTO-PARALLEL BIAS FOR WIDE-BASELINE SEMI-GLOBAL MATCHING
Authors: Roth L. , Mayer H.
Published: May 2019

Abstract. Semi-Global Matching (SGM) is a widely-used technique for dense image matching that is popular because of its accuracy and speed. While it works well for textured scenes, it can fail on slanted surfaces particularly in wide-baseline configurations due to the so-called fronto-parallel bias. In this paper, we propose an extension of SGM that utilizes image warping to reduce the fronto-parallel bias in the data term, based on estimating dominant slanted planes. The latter are also used as surface priors improving the smoothness term. Our proposed method calculates disparity maps for each dominant slanted plane and fuses them to obtain the final disparity map. We have quantitatively evaluated our approach outperforming SGM and SGM-P on synthetic data and demonstrate its potential on real data by qualitative results. In this way, we underscore the need to tackle the fronto-parallel bias in particular for wide-baseline configurations in both the data term and the smoothness term of SGM.
Alex North's Flute Music inDeath of a Salesman
Authors: Thomson Ian
Published: May 2019

An earlier essay, “The Flute in Death of a Salesman” (hereafter “first essay”), concluded that the flute that is heard at the beginning and end of the play is an essential feature and should not be omitted in performance. The music played by the flute was written by Alex North and approved by Miller, and Albert Music, L.A., the owner of the copyright for the printed music, has now kindly permitted its reproduction with a commentary in this journal. This allows North's influence to be examined openly and more coherently than has been the case to date. It is evident that North's composition contains features that signpost issues in the drama: text and flute music are cleverly integrated. Why then do so many theater directors disregard North's music?
The “Rag Doll” Won't Move: The Curious Case of Sylvia Gellburg
Authors: Singh Ambika , Tandon Nupur
Published: May 2019

Arthur Miller has often been criticized for creating an androcentric environment onstage, but if Kate Keller and Linda Loman were victims in the male world, the female condition seems to only have worsened in his later stage plays of the 1990s and early 2000s. However, despite the voluminous feminist criticism hurled at the playwright, it is essential to recognize Miller as a truthful chronicler of his times for he efficaciously uses the dramatic stage as a mirror image of his society. This article investigates the curious case of Sylvia Gellburg, the paralyzed Jewish American housewife of Miller's Broken Glass (1994), by connecting her “hysteria” to her subjugation as a woman of the 1930s, and justifying Miller's portrayal of women as realistic instead of demeaning. In simpler terms, the article is a defense of Miller's art of characterization.
Chaucer's Other Wyf: Philippa Chaucer, the Critics, and the English Canon
Authors: Seal Samantha Katz
Published: May 2019

This article surveys the critical history of scholarship on Philippa Chaucer, the wife of the famous English poet. Beginning with the late Victorian work of Frederick Furnivall and ending with contemporary biographies of Geoffrey Chaucer, this article argues that male critics have constructed their depictions of Philippa Chaucer with little reference to historical fact. Instead, male critics have formed an intellectual community with one another (and with the medieval poet) by the act of denigrating Philippa, with an appeal to a supposedly universal knowledge about disagreeable women and their effect on men of genius. From harpy to harlot to cold careerist, Philippa Chaucer's life and relationship with her husband have proved flexible media for male critics to manipulate. The biographical evaluations published over the last century therefore have much to reveal about the intellectual priorities and gender prejudices of her husband's critics.
