Use of Social Network Analysis for Tax Control in Spain

The Spanish Tax Agency is an experienced user of big data and has now deployed social network analysis (SNA) tools. SNA tools have led to a qualitative leap in such wide-ranging areas as tax collection, enforcement, control of ultra-high-net-worth individuals, and money laundering. This paper presents a comprehensive overview of the different lines of research, strategies and results of nine projects over the last five years, including the lessons learned. We present the best practices in pattern discovery, the tools developed for the control of big fortunes and the strategy developed to create a bridge between expert knowledge and SNA technologies. We highlight the results of investigating interposed entities used to channel personal remuneration, complex corporate structures, and opaque companies.

Managing Open Access (OA) Scholarly Information Resources in a University

Open Access (OA) to scholarly information has now become a reality. Due to the efforts of OA supporters worldwide now even commercial publishers have started supporting open access to their content through various open access models. Many public institutions like universities and R&D Labs have realized the importance of OA in developing the society in general. As a result, these institutions have come up with OA repositories, archives and libraries. As with any such proliferation of information, OA resources have increased manifold and can easily overwhelm even an experienced user. Also different repositories may use various digital library software, which presents the problem of multifarious search interfaces and features. The solution can be found in the open community of open source software and open standards. The open source metadata harvesting software PKP-OHS and the open protocol for metadata harvesting i.e. OAI-PMH come to the rescue. This chapter discusses how PKP-OHS was implemented as a pilot study at the Central University of Himachal Pradesh (CUHP).

Observations on the Effects of Skill Transfer through Experience Sharing and In-Person Communication

An essential part of any space in which physical prototyping and prototype-driven product development is being conducted is the education of its users in the necessary skills to fully utilise the material resources of the space. This paper describes how two different skills were transferred between five projects in our research laboratory, TrollLABS. Based on the observed skill-transfers in the production of PCBs and use of RF-communication in mechatronics projects certain tendencies emerged: How the use of forced vocal experience sharing; And in-person transferring of skills has impacted the acquired skills of the learner. The observations further show that through the guidance of a more experienced user the learner is able to make “skill-jumps”: Intermediate skill steps, as well as underlying detailed knowledge, are skipped and the learner is able to reach a high skill level in a shorter time than the original acquirer of the skill. Furthermore, skills are retained in the space through cross-generational collaboration and communication. This article aims to share these insights and provide a starting point for answering some of the challenges of modern maker spaces.

Quality and Relevance of Illustrations in Approved Primary School Textbooks

However, some approved primary school textbooks in Kenya might contain low quality and irrelevant illustrations that inhibit their use. This study sought to evaluate the quality and relevance of illustrations in approved textbooks in Uasin Gishu County in Kenya so as to recommend strategies for determining their preparation and production. The objectives of the study were to establish the criteria for determining the quality and relevance of illustrations, to determine factors contributing to the quality and relevance of illustrations, and to examine challenges faced while dealing with illustrations. The study was guided by the gatekeeping theory. The researchers adopted an exploratory survey design involving 191 respondents. Questionnaires and interviews were used to collect data. The findings established that specific criteria for determining the quality and relevance of illustrations were lacking, and that expertise, time, technology, and printing materials were factors that contributed to the quality and relevance of illustrations. The results revealed that primary schools experienced user-related challenges, and that publishers experienced preparation and production challenges. Vetting and approving authorities’ challenges emanated from the preparation of the illustrations. Important recommendations include that adequate criteria for determining the quality and relevance of illustrations be formulated by the vetting authorities, that the preparation and production of illustrations be given professional attention by the publishers, and that government support textbook development and involvement of subject teachers from all regions in the evaluation panels. The study has implications for decolonising teaching and learning.

A New PC-Based Text Entry System Based on EOG Coding

Some disadvantages of optical eye tracking systems have increased the interest to EOG (Electrooculography) based Human Computer Interaction (HCI). However, text entry attempts using EOG have been slower than expected because the eyes should move several times for entering a character. In order to improve the writing speed and accuracy of EOG based text entry, a new method based on the coding of eye movements has been suggested in this study. In addition, a real time EOG based HCI system has developed to implement the method. In our method all characters have been encoded by single saccades in 8 directions and different dwell time. In order to standardize dwell times and facilitate the coding process, computer assisted voice guidance was used. A number of experiments have been conducted to examine the effectiveness of the proposed method and system. At the end of the fifth trials, an experienced user was able to write at average 13.2 wpm (5 letters = 1 word) with 100% accuracy using the developed system. The results of our experiments have shown that text entry with the eye can be done quickly and efficiently with the proposed method and system.

Introduction to Games User Research

This chapter provides an introduction to the field of Games User Research (GUR) and to the present book. GUR is an interdisciplinary field of practice and research concerned with ensuring the optimal quality of usability and user experience in digital games. GUR inevitably involves any aspect of a video game that players interface with, directly or indirectly. This book aims to provide the foundational, accessible, go-to resource for people interested in GUR. It is a community-driven effort—it is written by passionate professionals and researchers in the GUR community as a handbook and guide for everyone interested in user research and games. We aim to provide the most comprehensive overview from an applied perspective, for a person new to GUR, but which is also useful for experienced user researchers.

Preparation for Capturing Human Skills during Tooling Tasks Using Redundant Markers and Instrumented Tool

In recent years, robots have found extensive applications in automating repetitive, defined, position dependent tasks such as painting and material handling. However, continuous contact type tasks (such as finishing, deburring and grinding) that require both position and force control are still carried out manually by skilled labor. Majorly, because it is difficult to program experienced user skills in a robotic setup without having clear knowledge of underlying model used by the operators. In this paper we present a preparation for capturing human operator’s dynamics using an instrumented hand-held tool and a motion capture setup. We first present the design of an instrumented tool and later present a method for reliably capturing kinematics using redundant markers removing effects of marker occlusions, and effect of gravity caused by the tool's mass. Kinematic information is used for deriving the forces/torques on the tool end effector.
