Hexarray: A Novel Self-Reconfigurable Hardware System

Evolvable hardware (EHW) is a powerful autonomous system for adapting and finding solutions within a changing environment. EHW consists of two main components: a reconfigurable hardware core and an evolutionary algorithm. The majority of prior research focuses on improving either the reconfigurable hardware or the evolutionary algorithm in place, but not both. Thus, current implementations suffer from being application oriented and having slow reconfiguration times, low efficiencies, and less routing flexibility. In this work, a novel evolvable hardware platform is proposed that combines a novel reconfigurable hardware core and a novel evolutionary algorithm. The proposed reconfigurable hardware core is a systolic array, which is called HexArray. HexArray was constructed using processing elements with a redesigned architecture, called HexCells, which provide routing flexibility and support for hybrid reconfiguration schemes. The improved evolutionary algorithm is a genome-aware genetic algorithm (GAGA) that accelerates evolution. Guided by a fitness function the GAGA utilizes context-aware genetic operators to evolve solutions. The operators are genome-aware constrained (GAC) selection, genome-aware mutation (GAM), and genome-aware crossover (GAX). The GAC selection operator improves parallelism and reduces the redundant evaluations. The GAM operator restricts the mutation to the part of the genome that affects the selected output. The GAX operator cascades, interleaves, or parallel-recombines genomes at the cell level to generate better genomes. These operators improve evolution while not limiting the algorithm from exploring all areas of a solution space. The system was implemented on a SoC that includes a programmable logic (i.e., fieldvii programmable gate array) to realize the HexArray and a processing system to execute the GAGA. A computationally intensive application that evolves adaptive filters for image processing was chosen as a case study and used to conduct a set of experiments to prove the developed system robustness. Through an iterative process using the genetic operators and a fitness function, the EHW system configures and adapts itself to evolve fitter solutions. In a relatively short time (e.g., seconds), HexArray is able to evolve autonomously to the desired filter. By exploiting the routing flexibility in the HexArray architecture, the EHW has a simple yet effective mechanism to detect and tolerate faulty cells, which improves system reliability. Finally, a mechanism that accelerates the evolution process by hiding the reconfiguration time in an “evolve-while-reconfigure” process is presented. In this process, the GAGA utilizes the array routing flexibility to bypass cells that are being configured and evaluates several genomes in parallel.
Identification of pests and diseases of Dalbergia hainanensis based on EVI time series and classification of decision tree

In the process of vegetation remote sensing information extraction, the problem of phenological features and low performance of remote sensing analysis algorithm is not considered. To solve this problem, the method of remote sensing vegetation information based on EVI time-series and the classification of decision-tree of multi-source branch similarity is promoted. Firstly, to improve the time-series stability of recognition accuracy, the seasonal feature of vegetation is extracted based on the fitting span range of time-series. Secondly, the decision-tree similarity is distinguished by adaptive selection path or probability parameter of component prediction. As an index, it is to evaluate the degree of task association, decide whether to perform migration of multi-source decision tree, and ensure the speed of migration. Finally, the accuracy of classification and recognition of pests and diseases can reach 87%--98% of commercial forest in Dalbergia hainanensis, which is significantly better than that of MODIS coverage accuracy of 80%--96% in this area. Therefore, the validity of the proposed method can be verified.
Green Route Synthesis and Characterization of ZnO Nanoparticles using spathodea campanulata

Nanoparticles have most of their constituting atoms on their surfaces and are similar to biomolecules making them have unique and noble properties compared to their bulk counterparts. They have thus received tremendous research focus and immense applications in sensors, medicine, cosmetics, optoelectronics, environmental protection, information storage and in catalysis. Biological methods of synthesizing nanoparticles specifically using plants are currently under exploitation due to the fact that they are cost effective and environmentally friendly way of synthesizing nanoparticles. In the present study, zinc oxide nanoparticles (ZnO NPs) were successfully synthesized using zinc nitrate and aqueous leave extract of Spathodea campanulata as the reducing as well as stabilizing agent. Formation of nanoparticles was monitored using UV-Visible spectroscopy and a characteristic absorption peak at 328nm was observed. From the transmission electron microscope (TEM) images, the synthesized ZnO nano-crystallites were of uniform morphology and size range of 20-50nm. XRD characterization revealed the face-centered cubic of highly crystalline nanoparticles indexed to (JCPDS card No. 36-1451). SEM images revealed spherically shaped and smooth surfaced nanoparticles arranged on top of one another. The EDX gave strong signals for zinc and oxygen at energies 137.6888 units and 118.0190 units, respectively, indicating the occurrence of the nanoparticles in their oxide form rather than the pure zinc form. From the FTIR spectra of the zinc oxide nanoparticles, the characteristic absorption peak of Zn-O bond was observed at 848cm-1. The spectra of the Spathodea campanulata extract gave an O-H stretch of polyphenols at 3222cm-1, nitrile group from proteins at 2339cm-1 and double substituted aromatic bending at 682cm-1.
Leadership and the contagion of affective phenomena: A systematic review and mini meta‐analysis

We present a systematic review of literature examining leadership and the contagion of affective phenomena, namely emotion, mood and affect. Specifically, an inductive thematic analysis approach was adopted to synthesize the findings from published studies. In addition, a mini meta-analysis was conducted to quantify reported effects. A rigorous search identified 25 studies that fulfilled the inclusion criteria for further review. Results highlighted important relationships between leadership and contagion aligned with six themes: charismatic and transformational leadership are conducive to contagion of leader and follower positive A cc ep te d A rt ic le This article is protected by copyright. All rights reserved. affective phenomena; greater contagion effects exists when there is congruence between leader and follower affective states; contagion of leader and follower affective phenomena is directly linked to leader effectiveness and performance; and, individual susceptibility to the contagion of affective phenomena can moderate these relationships. These findings have salient implications for conceptualization and measurement across multiple lines of inquiry and within numerous domains of application.
The Influences of Job Satisfaction and Performance on Employees Followership Styles: A Survey in the Malaysian Health Institution

The present study examined the influences of job satisfaction and job performance on followership style among employees from one of the public health institution in the Northern Malaysia. This study utilized the questionnaire method. A total of 210 respondents including the administrative staff, medical officer and nurses participated in this study. The findings presented that employees in this institution have moderately high levels of followership style (mean=3.67), job satisfaction (mean=3.67) and job performance (mean=3.37). Results presented that job satisfaction is significantly related to followership style (β=.72, p=.00); and job performance is not significantly related to followership style (β=-.11, p=.12). Thus, it is found that only job satisfaction has a significant influence on followership style among employees in this institution. This study contributed some fruitful knowledge which can be suggested to all of the Malaysian public health institution, particularly to improve the level of followership style. Implications of the results are discussed; and limitations of this study are briefly highlighted.
‘It’s music and we came to play instruments’: teaching for engagement in classroom music

ABSTRACT This paper presents findings from ethnographic case study research that investigated teacher practices and student engagement in classroom music. The data collection was undertaken in a primary (elementary) and a secondary school in Australia and focussed on the classroom practice of two teachers and four classes of students aged 10 to 16 years. The two teachers invited to participate in the study had been identified as being influenced by the Musical Futures approach following their participation in a Musical Futures professional learning workshop. The findings draw on participant-observation of music lessons, interviews, and focus groups. From this research, a model of teaching for engagement in classroom is proposed. This paper discusses three over-arching themes that comprise the model, illustrated with classroom snapshots from secondary Year 10 and Year 7 music classes and primary Year 5/6 music classes.
Review on Psychological Stress Detection Using Biosignals

This review investigates the effects of psychological stress on the human body measured through biosignals. When a potentially threatening stimulus is perceived, a cascade of physiological processes occurs mobilizing the body and nervous system to confront the imminent threat and ensure effective adaptation. Biosignals that can be measured reliably in relation to such stressors include physiological (EEG, ECG, EDA, EMG) and physical measures (respiratory rate, speech, skin temperature, pupil size, eye activity). A fundamental objective in this area of psychophysiological research is to establish reliable biosignal indices that reveal the underlying physiological mechanisms of the stress response. Motivated by the lack of comprehensive guidelines on the relationship between the multitude of biosignal features used in the literature and their corresponding behaviour during stress, in this paper, the impact of stress to multiple bodily responses is surveyed. Emphasis is put on the efficiency, robustness and consistency of biosignal data features across the current state of knowledge in stress detection. It is also explored multimodal biosignal analysis and modelling methods for deriving accurate stress correlates. This paper aims to provide a comprehensive review on biosignal patterns caused during stress conditions and reliable practical guidelines towards more efficient detection of stress.
Effects of a Multi-Session Cognitive Training Combined With Brain Stimulation (TrainStim-Cog) on Age-Associated Cognitive Decline – Study Protocol for a Randomized Controlled Phase IIb (Monocenter) Trial

Background With increasing aging populations worldwide, developing interventions against age-associated cognitive decline is particularly important. Evidence suggests that combination of brain stimulation with cognitive training intervention may enhance training effects in terms of performance gain or transfer to untrained domains. This protocol describes a Phase IIb clinical trial that investigates the intervention effects of training combined with brain stimulation in older adults. Methods The TrainStim-Cog study is a monocentric, randomized, single-blind, placebo-controlled intervention. The study will investigate cognitive training with concurrent anodal transcranial direct current stimulation (tDCS) over the left dorsolateral prefrontal cortex (target intervention) compared to cognitive training with sham stimulation (control intervention) over nine sessions in 3 weeks, consisting of a letter updating task, and a three-stage Markov decision-making task. Fifty-six older adults will be recruited from the general population. Baseline assessment will be performed including neuropsychological screening and performance on training tasks. Participants will be allocated to one of the two study arms using block-wise randomization stratified by age and baseline performance with a 1:1 allocation ratio. Primary outcome is performance in the letter updating task after training under anodal tDCS compared to sham stimulation. Secondary outcomes include performance changes in the decision-making task and transfer tasks, as well as brain structure and functional networks assessed by structural, and functional magnetic resonance imaging (MRI) that are acquired pre- and post-intervention. Significance The main aim of the TrainStim-Cog study is to provide evidence for behavioral and neuronal effects of tDCS-accompanied cognitive training and to elucidate the underlying mechanisms in older adults. Our findings will contribute toward developing efficient interventions for age-associated cognitive decline. Trial registration This trial was retrospectively registered at Clinicaltrials.gov Identifier: NCT03838211 at February 12, 2019, https://clinicaltrials.gov/ct2/show/NCT03838211. Protocol version Based on BB 004/18 version 1.2 (May 17, 2019).
Analysis of Interactive Metadiscourse in Chinese Students’ IELTS Writing

IELTS Writing testis considered as the most difficult part of IELTS exam. That’s why research interest always focuses on the analysis of the linguistics feature of students’ IELTS compositions. Analysis of linguistic features in students’ IELTS compositions is a good way to analyze and enhance students’ writing ability. In this essay, Hyland's (2005) interactional model of metadiscourse was adopted to analyze 20 students’ IELTS writing to explore the linguistic features of students’ writing. A research is designed to analyze and explore the differences in the application of metadiscourse markers in students’ composition and model essay templates and then based on the research results, marked variations are found across students’ writing and model essays in terms of interactive metadiscourse markers. In the final part, the author suggests more interactive textual metadiscourse markers should be used by students to make their writing more organized and coherent.
Indigenous-Hybrid Organisations in Colombia: A Multi-Level Analysis within the Buen Vivir Model

There has been a recent increase in the number of publications about the indigenous philosophy of Buen Vivir (BV) as an alternative paradigm to mainstream development theory. However, there is a dearth of theoretically grounded empirical research that interrogates the impact of BV as an alternative development model within the social and solidarity economy (SSE) in Latin America. Therefore, this thesis aims to address this research gap by investigating the development of indigenous community based organisations (ICOs) that are located within the SSE in Colombia, examining to what extent their experiences embody key tenets of the BV model. By drawing upon insights from post-development (BV) and postcolonial theories (Bhabha’s mimicry and hybridity), this thesis develops and critically explores a multi-level model for understanding the development of ICOs in Colombia, considering the micro, meso and macro levels. Using participatory video research, this research draws upon evidence from a multiple case study research with five indigenous communities (Curripaco, Puinave, Yanacona, Misak and Wayuu) in three geographic regions (the Amazons, Cauca and Guajira). The thesis uses the following types of data collection: secondary data sources, video focus groups, video semi-structured interviews, observations and field notes. The analysis of the multiple case study using Nvivo, discovers that ICOs operate as hybrid organisations that are influenced by their indigenous cultural practices, as well as the dominant Western forms legitimised by the SSE norms (mimicry). Overall, this thesis reveals that the ICOs’ experiences are consistent with the values and pillars that embody the key tenets of the BV model. The findings demonstrate that the current policy discourse provides little scope for engagement for ICOs in Colombia, even though evidence shows their contribution to the national economy. In doing so, this thesis offers an opportunity for policy makers to rethink and re-evaluate the existing policies in relation to indigenous communities and the SSE sector, to provide a pathway consistent with some elements of the BV model to contribute to the national development plan.
Protective Factors for Violent Victimization in Schools: A Gendered Analysis

ABSTRACT While the link between childhood abuse and future victimization has been developed, the effects of other negative events in childhood on future victimization, and whether protective factors may guard against it, remains unclear. To address this topic, the relationships between Adverse Childhood Experiences (ACES), protective factors, and violent school victimization were assessed using a sample of 12,850 boys and 14,121 girls in 8th, 10th, and 12th grades. Non-abuse ACES items were found to significantly predict violent school victimization for both boys and girls, and protective factors were found to moderate the relationship between the two in several instances. Future research should examine ACES items separately by gender, and the cumulative effect that different protective factors may have on juvenile victimization.
Insights into Collaborative Platforms for Social Media Use Cases

The first social network has been created 30 years ago and allowed users to create a profile, add friends or use chat rooms. In time social media evolved to social platforms like Facebook, Twitter or Instagram, which in fact are a huge mine of information for brands, vendors or even companies. Thus, marketing and recruiting processes are parts of today’s social media. By analyzing and understanding consumers’ activity on social media, companies have a powerful tool available for use. They can develop their advertising campaign or as close as possible to the needs of users or target most relevant applicants’ profiles for recruiting purposes. In this context, we bring an innovative platform that integrates Digital Interaction Intelligence (DII) for data processing based on intelligent techniques and Digital Interaction Data (DID) for data aggregation, persistence and user interaction. Building such a platform required to study, compare and select the adequate collaborative platform for our goals, having in mind a scalable design for further developments in other use cases.
Divine, interpersonal and self-forgiveness: Independently related to depressive symptoms?

ABSTRACT Interpersonal forgiveness, self-forgiveness and divine forgiveness have all been related to depressive symptoms. But does each type of forgiveness account for unique variance in depression? Two studies examine this question. Study 1 (n = 574) showed that each form of forgiveness was related to concurrent depressive symptoms independently of the other two. The magnitude of the association was highest for self-forgiveness, followed by interpersonal forgiveness and then divine forgiveness. Study 2 (n = 446) provides a conceptual replication and extension of Study 1. Although all three types of forgiveness again accounted for unique variance in concurrent depressive symptoms, only interpersonal and self-forgiveness predicted depressive symptoms 10 weeks later. To help understand these findings the features of each type of forgiveness are re-examined. Several limitations of the studies and paths for future research are outlined.
The Whole Story: The Dilemma of the Domestic Violence Protection Order Narrative

The complaint narrative, in which victims describe their experiences of abuse as part of the domestic violence protection order application process, has been questioned on the basis that quality and outcome might vary depending on who completes the form. Using a mixed-methods narrative analysis approach, we advance this inquiry by examining whether distinct ‘types’ of narratives can be identified across a sample of protection order application narratives from the state of Queensland in Australia. We find three distinct narrative types that are differently associated with who makes the application and the protection order outcome. The results underscore the unevenness in the protection order process and equitable access to justice more broadly.
Correlates of the joint attention disturbance in autism

Deficits in joint attention, imitation, and pretense are believed to contribute to subsequent difficulty in trie development of a theory of mind in children with autism (Baron-Cohen, 1991; Mundy, 1995). Joint attention and other early social skills of children with autism (34 male, 4 female; ages 4 to 18 years) were correlated with measures of nonverbal cognitive ability (Leiter International Performance Scale), receptive and expressive language skills (Peabody Picture Vocabulary Test -Revised and Expressive One-Word Picture Vocabulary TestRevised), and the severity of autism (Childhood Autism Rating Scale) to gain a better understanding of these developmental relationships. Joint attention and other early social skills were measured with the Social Interest Inventory (Sll), a questionnaire developed for this study and completed by Parents and Teachers. Subjects with autism at all levels of cognitive and language ability were found to have deficits in joint attention, imitation, and pretense. Joint attention deficits were not correlated to the acquisition of language or to the cognitive ability of the subjects. This is a deviance from the typical course of development However, deficits in joint attention, imitation, and pretense showed significant correlations with the overall severity of autism. Students with autism reportedly engage in significantly higher levels of instrumental than social communication and parents tend to rate their children somewhat higher than teachers on several Sll measures. Joint attention deficits may have a more profound effect on how language and cognitive skills are used by children with autism than on how they are acquired. Interventions which focus primarily on the cognitive and language abilities of children with autism may overlook more basic social skills such as joint attention which may warrant more direct intervention.
Patriarchal attitudes in two selected isiXhosa literary texts

This paper addresses problems concerning patriarchy and its undisputable connection to the demotion of women, using a feminist point of view. The question of patriarchal dominance and inequalities in African societies has been a trendy topic for decades and resulted from women's deprivation of the freedom of expression. This article seeks to show how the predominantly patriarchal isiXhosa culture is imbued with negative connotations towards women as depicted in two selected isiXhosa plays, namely Iinkunzi ezimbini by H Mothlabane and Inene nasi isibhozo by A Mtingane. The article also compares the presentation of the relationship between men and women in society, with particular emphasis on domestic and gender roles. The findings of this article, based on an analysis of the two literary texts, show to what extent isiXhosa culture is still inherently patriarchal. Finally, it is proposed that patriarchy is the reason for the problem of female subordination today.
