Children’s rights in the digital age

The digital divide exacerbates inequalities in access to information and knowledge, making it more difficult to socialize with peers and limiting awareness of and the ability to use basic tools for life in society. Reducing this gap sets in motion virtuous synergies of social and cultural inclusion for children and adolescents, facilitating skills development and generating lifelong opportunities. Although the younger generations are connected digital natives, inequalities persist among socioeconomic groups, though these have been tempered by connectivity programmes in public schools in the region. The main article of this edition of Challenges uses current information to examine the progress made and the gaps that remain in this area. Providing children and adolescents with access is merely a first step. They then need to be protected from the risks associated with information and communications technologies (ICTs), which must be harnessed for purposes of meaningful learning, promoting uses that are more in line with the educational curriculum. Lastly, the article posits that connectivity policies must be linked to the fulfilment of children’s rights in the framework of the Convention on the Rights of the Child. As is customary, this issue also contains information on meetings and conferences held in the region during the year and recent publications in this field. Mention is also made of good practices from Peru in reducing gender gaps and a joint initiative between mobile operators and the United Nations Children’s Fund (UNICEF) to protect children in the digital age. Viewpoints includes expert opinion on the potential of ICTs as tools that can facilitate the exercise of the rights of children and adolescents, but also lead to violations of these rights.

Working paper on the eLAC 2018 Digital Agenda in consideration of Caribbean priorities for technology-supported development

eLAC 2018 will coordinate the implementation of programmes to support the use of information and communications technologies (ICTs) in achieving social and economic development goals for Latin America in the Caribbean during the 2015-2018 timeframe. The conceptual framework for this programme of work is described by the eLAC 2018 Digital Agenda, which is anticipated to be ratified by the fifth Ministerial Conference on the Information Society in Latin America and the Caribbean, to be held in August 2015 in Mexico City. There is a need for broader input from Caribbean countries to the eLAC 2018 Digital Agenda. Accordingly, this working paper reviews the document’s current draft, considering each of its objectives in the context of Caribbean development needs. Amendments are recommended to 12 of the objectives. Two additional objectives are also proposed, in the areas of regional coordination on universal service funds, and the establishment of a spatial data infrastructure to support the use of geographic information systems. Representatives of Caribbean countries are invited to use the contents of this document as an input to the development of their own proposed amendments for inclusion in the final version of the eLAC 2018 Digital Agenda.

Numerical Modelling of Graphene Nanoribbon-fets for Analog and Digital Applications

Graphene, that is a monolayer of carbon atoms arranged in a honeycomb lattice, has been isolated only recently from graphite. This material shows very attractive physical properties, like superior carrier mobility, current carrying capability and thermal conductivity. In consideration of that, graphene has been the object of large investigation as a promising candidate to be used in nanometer-scale devices for electronic applications. In this work, graphene nanoribbons (GNRs), that are narrow strips of graphene, for which a band-gap is induced by the quantum confinement of carriers in the transverse direction, have been studied. As experimental GNR-FETs are still far from being ideal, mainly due to the large width and edge roughness, an accurate description of the physical phenomena occurring in these devices is required to have valuable predictions about the performance of these novel structures. A code has been developed to this purpose and used to investigate the performance of 1 to 15-nm wide GNR-FETs. Due to the importance of an accurate description of the quantum effects in the operation of graphene devices, a full-quantum transport model has been adopted: the electron dynamics has been described by a tight-binding (TB) Hamiltonian model and transport has been solved within the formalism of the non-equilibrium Green's functions (NEGF). Both ballistic and dissipative transport are considered. The inclusion of the electron-phonon interaction has been taken into account in the self-consistent Born approximation. In consideration of their different energy band-gap, narrow GNRs are expected to be suitable for logic applications, while wider ones could be promising candidates as channel material for radio-frequency applications.

Reference values for digital X-ray radiogrammetry parameters in children and adolescents in comparison to estimates in patients with distal radius fractures.

The first objective of this study was to determine normative digital X-ray radiogrammetry (DXR) values, based on original digital images, in a pediatric population (aged 6-18 years). The second aim was to compare these reference data with patients suffering from distal radius fractures, whereas both cohorts originated from the same geographical region and were evaluated using the same technical parameters as well as inclusion and exclusion criteria. DXR-BMD and DXR-MCI of the metacarpal bones II-IV were assessed on standardized digital hand radiographs, without printing or scanning procedures. DXR parameters were estimated separately by gender and among six age groups; values in the fracture group were compared to age- and gender-matched normative data using Student's t tests and Z scores. In the reference cohort (150 boys, 138 girls), gender differences were found in bone mineral density (DXR-BMD), with higher values for girls from 11 to 14 years and for boys from 15 to 18 years (p < 0.05). Girls had higher normative metacarpal index (DXR-MCI) values than boys, with significant differences at 11-14 years (p < 0.05). In the case-control investigation, the fracture group (95 boys, 69 girls) presented lower DXR-BMD at 15-18 years in boys and 13-16 years in girls vs. the reference cohort (p < 0.05); DXR-MCI was lower at 11-18 years in boys and 11-16 years in girls (p < 0.05). Mean Z scores in the fracture group for DXR-BMD were -0.42 (boys) and -0.46 (girls), and for DXR-MCI were -0.51 (boys) and -0.53 (girls). These findings indicate that the fully digital DXR technique can be accurately applied in pediatric populations ≥ 6 years of age. The lower DXR-BMD and DXR-MCI values in the fracture group suggest promising early identification of individuals with increased fracture risk, without the need for additional radiation exposure, enabling the initiation of prevention strategies to possibly reduce the incidence of osteoporosis later in life.

Systematic literature review of digital three-dimensional superimposition techniques to create virtual dental patients

PURPOSE Digital developments have led to the opportunity to compose simulated patient models based on three-dimensional (3D) skeletal, facial, and dental imaging. The aim of this systematic review is to provide an update on the current knowledge, to report on the technical progress in the field of 3D virtual patient science, and to identify further research needs to accomplish clinical translation. MATERIALS AND METHODS Searches were performed electronically (MEDLINE and OVID) and manually up to March 2014 for studies of 3D fusion imaging to create a virtual dental patient. Inclusion criteria were limited to human studies reporting on the technical protocol for superimposition of at least two different 3D data sets and medical field of interest. RESULTS Of the 403 titles originally retrieved, 51 abstracts and, subsequently, 21 full texts were selected for review. Of the 21 full texts, 18 studies were included in the systematic review. Most of the investigations were designed as feasibility studies. Three different types of 3D data were identified for simulation: facial skeleton, extraoral soft tissue, and dentition. A total of 112 patients were investigated in the development of 3D virtual models. CONCLUSION Superimposition of data on the facial skeleton, soft tissue, and/or dentition is a feasible technique to create a virtual patient under static conditions. Three-dimensional image fusion is of interest and importance in all fields of dental medicine. Future research should focus on the real-time replication of a human head, including dynamic movements, capturing data in a single step.

An examination of parental opinions regarding the inclusion of disabled students in regular education classes

This study investigated the opinions regarding inclusion of parents of both disabled and nondisabled elementary children from a large suburban county. An opinion survey combining Wilczenski's Attitudes Toward Inclusive Education Scale with additional questions was distributed to 1170 children from 24 schools. Three research questions focused on differences between mean parental responses as they related to the inclusion and disability status of the parent's child. Results from the 270 respondents indicated that parents with disabled children had more favorable opinions about inclusion than did those with nondisabled children. Parents with included children were more favorable toward inclusion than were parents whose children were not included. Parents with included disabled children were more accepting of inclusion than were those with nondisabled children in inclusive settings. Parents' answers differed depending on the type of disability being included. Regardless of their child's disability or inclusion status, the ranking for disability types from most acceptable for inclusion to least acceptable were: social, sensory, motor, academic and behavioral. Results across types of questions, including questions relating to acceptance and general inclusion issues, indicated consistently more favorable opinions of parents with disabled children, included children and disabled children in inclusive classes. Two additional research questions examined parental responses as they related to demographic characteristics of the parents and of the schools their children attended. Analysis of Variance found only one significant main effect for any parental demographic variable. This difference was for the number of parents' elementary children when comparing parents with and without disabled children. The only significant main effects of demographics of schools the parents' children attended were for the area of the county and for schools with differing percentages of severely disabled students when comparing responses of parents with disabled and nondisabled children. For all research questions, tests indicated low effect sizes and moderate to high power levels. These results, and the fact that means for all groups were in the middle range of response choices, indicate that there may be little practical significance to the overall results. Further studies should investigate the trends found in this study. ^
