Mining high utility sequential patterns

Sequential pattern mining refers to the identification of frequent subsequences in sequence databases as patterns. It provides an effective way to analyze the sequential data. The selection of interesting sequences is generally based on the frequency/support framework: sequences of high frequency are treated as significant. In the last two decades, researchers have proposed many techniques and algorithms for extracting the frequent sequential patterns, in which the downward closure property (also known as Apriori property) plays a fundamental role. At the same time, the relative importance of each item has been introduced in frequent pattern mining, and “high utility itemset mining” has been proposed. Instead of selecting high frequency patterns, the utility-based methods extract itemsets with high utilities, and many algorithms and strategies have been proposed. These methods can only process the itemsets in the utility framework. However, all the above methods suffer from the following common issues and problems to varying extents: 1) Sometimes, most of frequent patterns may not be informative to business decision-making, since they do not show the business value and impact. 2) Even if there is an algorithm that considers the business impact (namely utility), it can only obtain high utility sequences based on a given minimum utility threshold, thus it is very difficult for users to specify an appropriate minimum utility and to directly obtain the most valuable patterns. 3) The algorithm in the utility framework may generate a large number of patterns, many of which maybe redundant. Although high utility sequential pattern mining is essential, discovering
Development and trial of an online survey to investigate trust before the use of a technology

Trust is an important concept in social interaction. Research shows that trust is also of importance when people interact with technology. Extensive research has been conducted to measure trust when using technology. No research so far has looked into trust before the use of a product, which is of great importance for new products on the market. The current work aims at developing a tool (survey) to measure trust in medical devices for home usage (Home MDD’s) and testing the usability of that tool. The survey has been constructed in tune with the literature. Experts were asked to make a list of Home MDD’s and associated features that have been used in the survey. Participants filled the survey and were interviewed using a Retrospective Thinking Aloud (RTA) method. Suggestions for redesign were made based on the data of the interviews.
Suivi de l’engagement des apprenants lors de la construction de cartes mentales à partir de traces d’interaction

A la difference de l'apprentissage par memorisation (rote learning), l'apprentissage significatif (meaningful learning) vise a associer de nouvelles connaissances a des connaissances deja acquises. La construction de cartes mentales exige et supporte la mise en place de strategies d'apprentissage significatif, et permet de rendre visible la structure de connaissances de l'apprenant. Cependant, les enseignants qui integrent la construction de cartes mentales dans leurs activites pedagogiques doivent se contenter du rendu final des cartes mentales, et risquent de faire de mauvaises interpretations et evaluations de celles-ci par manque d'information sur leur processus de construction. Dans cette these, nous nous interessons a l'observation a posteriori de l'engagement de l'apprenant dans ses dimensions comportementale et cognitive, afin de proposer des indicateurs orientes processus qui permettent de comprendre ses actions et ses choix de construction de carte mentale. Nous avons suivi la methodologie de recherche orientee par la conception (Design Based Research), qui nous a permis de proposer 3 niveaux de contributions : 1) un modele theorique d'engagement (comportemental et cognitive) pour les activites de construction de cartes mentales, 2) un ensemble d'indicateurs d'engagement de l'apprenant a partir de traces capturees automatiquement lors de la construction de cartes mentales, et 3) un tableau de bord appele MindMap Monitor presentant differents indicateurs a l'enseignant pour le suivi de la classe et des apprenants. Le modele a ete obtenu a partir d'une etude de litterature sur les theories de l'engagement de l'apprenant issues notamment de la recherche en psychologie de l'education. Les indicateurs ont ete definis en croisant le modele avec les resultats de plusieurs etudes de terrain avec les enseignants. Le tableau de bord implementant les indicateurs a ete construit en trois iterations. Son interface presente des vues synthetiques permettant de comparer les eleves de la classe et d'identifier ceux en difficulte lors de la construction de leur carte, et des vues detaillees decrivant l'activite de construction d'une carte pour chaque eleve. Notre tableau de bord a ete evalue au cours d'une experimentation avec 12 enseignants en comparant son utilisation avec celle des cartes mentales finales associees aux videos de leur processus de construction. Les resultats montrent que nos indicateurs sur MindMap Monitor permettent de mieux identifier les eleves en difficulte, les difficultes partagees, ainsi que les difficultes pour un eleve. Les resultats concernant la comprehension du processus de construction de la carte mentale sont plus nuances. Nous avons egalement pu identifier plusieurs pistes d'amelioration sur le contenu du tableau de bord et sa presentation. Les perspectives de notre travail concernent principalement le suivi de l'engagement des apprenants en temps reel pour l'intervention et l'adaptation de la strategie pedagogique
Data governance activities: an analysis of the literature

Abstract Data governance is an emerging subject in the information system (IS) field. In recent years, the volume of data used within organisations has increased dramatically, playing a critical role in business operations. This paper explores the current literature on data governance and is intended to provide a comprehensive analysis of the activities involved in data governance. Six major academic databases in the IS domain were searched using key terms to identify and analyse material reflecting the current state of knowledge. A systematic procedure was developed to identify 31 papers that explicitly mention data governance activities. Open coding techniques were applied to conduct content analysis, resulting in 110 data governance activities across five decision domains of the data governance framework. These data governance activities are understood as: ‘action’ plus ‘area of governance’ plus ‘decision domain’ e.g. (define data policies for data quality). Our analysis shows a high volume of data governance activities associated with the ‘defining’ action of the areas of governance across the decision domains with a lack of reported on the ‘implementing’ and ‘monitoring’ actions.
Analysis and Implementation of the Computation of Dominator in CFG

Compilers use dominance information extensively during program analysis and optimization,such as data-flow analysis and the computation of static single-assignment forms.The iterative method to compute dominators was discussed in detail,in which dominator relation is represented by bit vector.Based on the result of dominators,the method to compute immediate dominator and dominator frontier was given.At last,experimental results of NPB and SPEC2000 were presented,which show that construction of intraprocedual CFG takes almost half of the total time; if goto statement is not contained in structural program,the iterative algorithm will finish in two iterations.
A Video-Mediated Critical Friendship Reflection Framework for ESL Teacher Education.

In teacher preparation years, teacher candidates are often required to use personal video recordings of classroom instruction to reflect on teaching and learning. While it is welldocumented that video supports, scaffolds, and transforms teacher reflection, the literature on ESL-focused video reflection is scant. The present study discusses how four, final semester, undergraduate teacher candidates engaged in critical friendship to reflect on personally recorded videos of instruction delivered to elementary-aged ESL students. Twelve critical friendship lesson feedback sessions were collected over a 15-week period and were analyzed through ethnographic research methods using friendship metaphors and a member checking process. The article presents a video-mediated critical friendship framework that ESL teacher educators can use to structure video-mediated dialogue with teacher candidates and concludes with a discussion surrounding the benefits of using critical friendship in ESL teacher education.
The Business of Art Therapy in Canada: What Are You Worth? Obstacles and Perceptions (Le marché de l'art-thérapie au Canada : Que valez-vous ? Obstacles et perceptions)

Abstract This preliminary research explores the relationship between art therapists and business. The author examines art therapists’ perceptions of business in Canada by collecting responses from 70 art therapist participants at an annual conference presentation regarding: what art therapists felt they are worth (regarding salary expectations), perceived obstacles to achieving their indicated salary, and their perceptions about the word "business. " Collected qualitative data was coded for themes and was quantitatively analyzed for frequency. Findings indicate that the participants' average expectation of annual salary (and what they felt they were realistically worth) was $73,836 CAD (approximately $55,377 USD). Furthermore, 162 responses were collected about perceived obstacles to achieving participants' expected salary. Top four obstacles identified were: 21.6% believed recognition of art therapy was a primary obstacle (i.e., what art therapy is, credentials, compensation); 18.5% identified funding and fees; 13% indicated having business skills; and 11% believed that their own self-esteem was a primary obstacle. The question regarding perceptions about business had 81 responses. Responses were coded as: positive, negative, hopeful, or unknown meaning. The author found that 31% were coded as negative perceptions, 23.5% were positive perceptions, and 16% were hopeful perceptions. More research is needed regarding the relationship between art therapy and business.
The Role of Professional Development in Improving Quality and Supporting Child Outcomes in Early Education and Care

A skilled workforce that understands the needs of children and can deliver high quality curricula to children with diverse needs, is required in order to realise the wide-ranging benefits that could follow from public investment in [early childhood education and care] ECEC provision (such as in-service Professional Development (PD)). It is well established in the literature that high quality ECEC is important for children's outcomes, and that variations in quality can be explained, to a large extent, by variations in educator pedagogy and practice. We argue for a better understanding of how ECEC educators and services can achieve (and be supported to optimise) children's development and learning outcomes. This paper argues for more rigorous PD designs, considered evidence-based content and delivery that are embedded within a rich evidence-base of practice, and that focus on educator effectiveness, practice change, and also on the benefits to children's learning and development. The paper draws upon effective PD literature and describes lessons learnt, focussing on the 'who', 'what' and 'how' of evaluation of effective inservice PD design and delivery.

NLOS error mitigation in TOA using Kalman filter

Three methods of mitigating the NLOS (non-line of sight) error in TOA (time of arrival) measurements were proposed, all of which were performed by Kalman filter. In the three methods, the iterative process of Kalman filter was modified in different ways according to the characteristics of the NLOS error in TOA measurements. Simulations showed that these methods could eliminate the random noise and the positive bias of the NLOS error in TOA measurements. Compared with the traditional algorithms of NLOS error mitigation, the proposed methods can obtain higher accuracy and realtime processing.
Who says there’s a problem? Preferences on the sending and receiving of prohibitive voice

Which employees are likely to warn leaders about threats to the workplace? When employees do speak up, will these messages gain the leader’s interest? In this article, we rely on theories of power to predict how employee characteristics (work prevention regulatory focus, closeness to the leader (leader-member exchange) and rank) influence whether employees send messages about threats (prohibitive voice). We also explore whether employee characteristics (closeness to the leader and rank) affect leaders’ attention to threat messages. In a two-wave field study with 55 leaders and 214 employees, we found that leaders were more likely to show interest in messages about threats from employees who they were not close to, but who had high rank. However, only employees with a strong work prevention regulatory focus and/or those of higher rank were likely to prioritize the sending of such messages. Although we also expected that employees who had a good relationship with the leader would send more information about threats, we found they were less likely to do so. This research suggests that there may be “opaque zones” in organizations, places where employees are unlikely to warn leaders about threats and where leaders will not pay attention even if they do.
Holistic Constructions in Heritage Russian and Russian as a Second Language: Divergence or Delay?

ABSTRACT The purpose of this paper is to give an overview of the strategies applied by young learners of Russian when naming a word in a vocabulary test. A total of 40 children took part in the experiment: 10 simultaneous Russian-Swedish bilingual children and 10 successive Russian-Swedish bilinguals who lived in Sweden, 10 children who moved to Russia and acquired Russian as a second language, and 10 monolingual Russian children living in Russia (as a control group). All the children were tested with the Russian version of Cross-Linguistic Tasks (CLT; Nenonen, Gagarina 2016). The results showed that the error pattern in all the groups of children seemed to be similar; yet, the acquisition of some structures appeared to be delayed in Russian Heritage Language (HL) children. Holistic constructions are common for all the children, but in bilingual children the effects of cross-linguistic influence (CLI) were also noticed. We argue that ‘atypical’ construction does not necessarily need to be disordered since the two languages of the HL child develop in contact with each other. However, a pattern of delayed acquisition can later lead to divergent development in the weaker language of bilingual children.
Cooperation in group for speaking out in the world : Role -play and jigsaw strategies to develop oral perfomance in a public school in Bogotá

This research study intends to identify, analyze, and interpret the effects of implementing roleplay and jigsaw, as strategies of cooperative learning, on students‟ hesitation in order to develop oral performance in third and fifth graders. This was applied by teacher-researchers at Jose Manuel Restrepo School which is part of the Bogota Bilingual Project. This research project used a mixed approach method and action research to analyze data collected, using the following instruments: tests, audio recordings, proforma and open-ended questionnaires. The findings of the study reveal that the students‟ hesitation did not change; instead they hesitated in a different way. At the beginning silent pauses were made because students were unfamiliar with the content, but then the hesitations changed to filled pauses, which means that they needed to rehearse the words but in general, students showed development in their oral performance.
The effect of self-regulation empowerment program training on neurocognitive and social skills in students with dyscalculia

Method: The study was a semi-experimental with pretest/posttest design and a control group. The study sample was consisted of 26 students with dyscalculia in Guilan Province, Iran, 2018, selected by the convenience sampling method and assigned into two groups (one experimental and one control). To collect the data, Tower of Hanoi Task, Stroop Test, Dual N-Back Task, Wisconsin Card Sorting Test, and Social Skills Rating System were used before and after the intervention. A twelve-session self-regulation empowerment program training was implemented for the experimental group.
Accelerated GPU Ray-casting Algorithm Based on Space Leaping

Ray-casting is a widely used basic volume rendering algorithm. It can get high quality image but suffers from high computational complexity. A single-pass ray-casting algorithm is developed based on GPU(graphics processing unit),and on the basis of this algorithm an accelerated algorithm is proposed based on space leaping technique. Noncontributing region in the volume data coded with octree data structure can be eliminated by space leaping. Then the burden of GPU may be reduced effectively. Only one fragment program is needed to generate ray direction,cast ray,skip empty voxels and terminate ray,et al. The experimental results illustrate the algorithm can significantly accelerate the reconstruction of the volume data containing a lot of empty voxels.
Women’s experience of perceived uncertainty: insights from emotional intelligence

Purpose Few organizational change studies identified the aspects of change that are salient to individuals and gender in specific and that influence their work outcomes. This paper aims to assess the potential mediating effect of emotional intelligence and the moderating effect of gender in the relationship of perceived change-related uncertainty and work outcomes. Design/methodology/approach The study analyzes the measurement model and the structural model using SmartPLS (v 3.2.7) on a sample of 413 employees working in the telecom sector collected through a non-experimental face-to-face method. Findings The findings support that emotional intelligence mediates the negative relationship between perceived change-related uncertainty and work outcomes. Moreover, emotional intelligence and gender have a significant interaction effect on work outcomes. Research limitations/implications The study uses the ability-based model of emotional intelligence to assess its impact on the proposed theoretical framework. Practical implications The findings suggest that organizations should hire more females at the workplace as they are less in number although they are more emotionally intelligent. As well as, females should be given equal opportunities to reach the top managerial positions by breaking the glass ceiling. Originality/value The study adds insights into existing knowledge; for instance, the study reveals that emotional intelligence competency is a sine qua non to personal control that delivers exceptional results in the context of perceived change-related uncertainty. The study also investigates the interaction effect of gender with emotional intelligence to scaffold the emotional intelligence competency over gender differences.

A Review of Literature on Word Sense Disambiguation

Artificial intelligence (AI) has been a major research area in the later quarter of 20 th century and is likely to be even more so in the 21 st century. A key part of AI is Word Sense Disambiguation (WSD) which deals with choosing the correct sense of a word in the given text. All human languages have words with multiple meaning and selecting the intended sense is important. This paper briefly describes various methods presently used for WSD and their relative effectiveness. WSD applications currently find application in Information Retrieval, Information Extraction, Automated Answering Machine, Speech Reorganization, Machine Translation among many others. WSD has promise for the future in taking AI to the next higher level.
