Construction of a Teaching Package on Promoting Prosocial Internet Use and Preventing Antisocial Internet Use

In the construction of the teaching package on the Internet use, two major moral characters, respect and responsibility, form the core theoretical basis. The respect character consists of respect for others and self-respect while the responsibility character contains social, civil, and global responsibility. There are a total of nine units on the Internet use in the junior secondary curriculum. There are two units in Secondary One curriculum: the first unit deals with cheating behavior and privacy issues concerning the Internet, and the second one discusses the effect of excessive use of the Internet on life and study. In Secondary Two curriculum, we discuss the following social phenomena on the Internet with students: online shopping, pornographic materials on internet, and infringement of a copyright. Finally, we have designed four units on the Internet use in Secondary Three curriculum which focuses more on the relationship between the Internet use and our health. We try to answer the question on how we can use the Internet healthily and also the possibility on how it may hurt us. Similar to the second unit in Secondary One curriculum, we have designed three more units on discussing the effects of excessive use of the Internet with students. We would like to alert students that ineffective use of the Internet will hurt us mentally and physically. For illustrative purposes, two units in the Secondary One and Two curriculums are outlined in this paper

Implementing an eleven year through-train model to complete Primary and Secondary Education , is it possible? Why Not? : some challenges and principles

As learning and teaching is moving away from imparting student with mere "knowledge", the simple one-size-fits-all solution of a prescribed years of schooling with some rigid and prescriptive subject syllabuses designated for different year-levels in primary and secondary schools will no longer meet the developmental needs of students. Logos Academy of Hong Kong has started an "Eleven-year Through-train Program in September 2002, to re-define the different key stages in primary, junior and senior secondary levels to provide a broad and balanced curriculum which maintains seamless continuity. The eleven-year program consists of three stages, each with its particular characteristics: Foundation Stage: (FS1- FS3); Developmental Stage: (DS1 - DS5) and Mastery Stage (MS1 - MS3). We have achieved some pleasing outcome so far and we believe that this re-definition of Key Learning Stages is forward looking and keeping abreast of global trends. If this "Eleven-year Through-Train Schooling System" model is proved to be successful, it will throw some light on a new schooling structure - which will have significant implications on the government's funding and planning policie

Implementing an eleven year through-train model to complete Primary and Secondary Education: creating a platform for accommodating the newest pedagogical practices and technologies in school

In educational transformation, Logos Academy of Hong Kong has started to create space in two aspects: to accommodate for new learning areas, and to use the most updated technologies for learning. In different Learning Stages, new learning areas like "Family Life Education", "Analytical study of Current Issues", Mind-mapping, MegaSkills and Media Education are introduced. The teachers will design different level- and age-appropriate activities and assignments that encourage the mastery of basic concepts and development of aesthetic appreciation, family life education, character formation, physique building and inquiry/research skills. Moreover, integrated tasks and projects intertwining with different study skills are mounted to enable the children to experiment creative designs and try out increasingly complex investigations. To facilitate learning and teaching, Logos Academy also creates new platforms to use the newest technologies for pre-lesson use, for lesson use, and for post-lesson use. It is reviewed that with the aid of some updated technologies, our teachers are committed to facilitate change, reflect on current practices, explore further improvements in new learning areas and to use the new technologies effectively - which will in turn enhance the effectiveness of integrated study skills, self-directed learning, team work and social interaction of the students

Implementing an eleven year through-train model to complete Primary and Secondary Education: an innovative curriculum design, and optimizing the roles of subject specialists in the early learning stages

In an eleven year "through-train" model, to construct a new road map for learning, Logos Academy of Hong Kong has delineated clearly the roles of "Homeroom Teachers" and "Subject Specialists". In the Foundation Stage (The first three years in Primary Schooling), the "Homeroom Teachers" will no longer teach most of the academic subjects for their respective Homeroom classes. They will undertake mainly pastoral care functions whilst different subject specialists are deployed to teach different subject areas accordingly. Each Subject teacher will teach ALL the classes within a year-band. In some Subjects like English Studies, two or three teachers will share the teaching load according to their specialties. After putting in practice for two years, evidence has shown that with this "Subject specialist across the year band" approach, the curriculum rigor has been strengthened and children have made much more remarkable progress in specific learning areas. Moreover, it has created space and opportunities for co-teaching and joint projects. This has in turn facilitated communication, collaboration and professional development of teachers in their subject specialty. Within the same subject area, the inter-teacher difference between classes of the same year level has been diminished, and the effectiveness of teaching and learning across the whole year-band may be better monitored and evaluated. The subject specialist is also in a better position to design and organize necessary follow-up actions (including enrichment or remedial work) more efficientl

Spherical and planar three-dimensional anti-de Sitter black holes

The technique of dimensional reduction was used in a recent paper (Zanchin et al, Phys. Rev. D66, 064022,(2002)) where a three-dimensional (3D) Einstein-Maxwell-Dilaton theory was built from the usual four-dimensional (4D) Einstein-Maxwell-Hilbert action for general relativity. Starting from a class of 4D toroidal black holes in asymptotically anti-de Sitter (AdS) spacetimes several 3D black holes were obtained and studied in such a context. In the present work we choose a particular case of the 3D action which presents Maxwell field, dilaton field and an extra scalar field, besides gravity field and a negative cosmological constant, and obtain new 3D static black hole solutions whose horizons may have spherical or planar topology. We show that there is a 3D static spherically symmetric solution analogous to the 4D Reissner-Nordstr\"om-AdS black hole, and obtain other new 3D black holes with planar topology. From the static spherical solutions, new rotating 3D black holes are also obtained and analyzed in some detail.Comment: 27 pages, uses "iopclass" files (Latex2e

Effects of APOE4 allelic dosage on lipidomic signatures in the entorhinal cortex of aged mice

Apolipoprotein E ε4 (APOE4) is the primary genetic risk factor for the late-onset form of Alzheimer's disease (AD). Although the reason for this association is not completely understood, researchers have uncovered numerous effects of APOE4 expression on AD-relevant brain processes, including amyloid beta (Aβ) accumulation, lipid metabolism, endosomal-lysosomal trafficking, and bioenergetics. In this study, we aimed to determine the effect of APOE4 allelic dosage on regional brain lipid composition in aged mice, as well as in cultured neurons. We performed a targeted lipidomic analysis on an AD-vulnerable brain region (entorhinal cortex; EC) and an AD-resistant brain region (primary visual cortex; PVC) from 14-15 month-old APOE3/3, APOE3/4, and APOE4/4 targeted replacement mice, as well as on neurons cultured with conditioned media from APOE3/3 or APOE4/4 astrocytes. Our results reveal that the EC possesses increased susceptibility to APOE4-associated lipid alterations compared to the PVC. In the EC, APOE4 expression showed a dominant effect in decreasing diacylglycerol (DAG) levels, and a semi-dominant, additive effect in the upregulation of multiple ceramide, glycosylated sphingolipid, and bis(monoacylglycerol)phosphate (BMP) species, lipids known to accumulate as a result of endosomal-lysosomal dysfunction. Neurons treated with conditioned media from APOE4/4 vs. APOE3/3 astrocytes showed similar alterations of DAG and BMP species to those observed in the mouse EC. Our results suggest that APOE4 expression differentially modulates regional neuronal lipid signatures, which may underlie the increased susceptibility of EC-localized neurons to AD pathology

Trends in Volunteer Mentoring in the United States: Analysis of a Decade of Census Survey Data

Over the past decade, considerable resources have been devoted to recruiting volunteer mentors and expanding mentoring programs. It is unclear whether these efforts have helped to counter the broader national trends of declining volunteer rates. The current study uses data from the Volunteering Supplement of the Current Population Survey (CPS), sponsored by the U.S. Census Bureau and U.S. Bureau of Labor Statistics, to explore population-level trends in mentoring over the past decade. Results suggest that mentoring rates have remained relatively stable over the past decade, but that the population of mentors has changed somewhat in terms of age, ethnicity, educational background, and region of the United States. In addition, certain sectors of the mentor population show higher rates of attrition from 1 year to the next. Findings have important implications for the development of recruitment, training, and mentor support practices within mentoring organizations, as well as policies designed to meet the needs of at-risk youth in the U.S

An Interdisciplinary Approach to Study the Performance of Second-generation Genetically Modified Crops in Field Trials: A Case Study With Soybean and Wheat Carrying the Sunflower HaHB4 Transcription Factor

Research, production, and use of genetically modified (GM) crops have split the world between supporters and opponents. Up to now, this technology has been limited to the control of weeds and pests, whereas the second generation of GM crops is expected to assist farmers in abiotic stress tolerance or improved nutritional features. Aiming to analyze this subject holistically, in this presentation we address an advanced technology for drought-tolerant GM crops, upscaling from molecular details obtained in the laboratory to an extensive network of field trials as well as the impact of the introduction of this innovation into the market. Sunflower has divergent transcription factors, which could be key actors in the drought response orchestrating several signal transduction pathways, generating an improved performance to deal with water deficit. One of such factors, HaHB4, belongs to the homeodomain-leucine zipper family and was first introduced in Arabidopsis. Transformed plants had improved tolerance to water deficits, through the inhibition of ethylene sensitivity and not by stomata closure. Wheat and soybean plants expressing the HaHB4 gene were obtained and cropped across a wide range of growing conditions exhibiting enhanced adaptation to drought-prone environments, the most important constraint affecting crop yield worldwide. The performance of wheat and soybean, however, differed slightly across mentioned environments; whereas the improved behavior of GM wheat respect to controls was less dependent on the temperature regime (cool or warm), differences between GM and wild-type soybeans were remarkably larger in warmer compared to cooler conditions. In both species, these GM crops are good candidates to become market products in the near future. In anticipation of consumers’ and other stakeholders’ interest, spectral analyses of field crops have been conducted to differentiate these GM crops from wild type and commercial cultivars. In this paper, the potential impact of the release of such market products is discussed, considering the perspectives of different stakeholders.Fil: González, Fernanda Gabriela.

The contribution of caregiver psychosocial factors to distress associated with behavioural and psychological symptoms in dementia

Copyright © 2016 John Wiley & Sons, Ltd. Objective: The objective of the study is to examine caregiver factors as predictors of BPSD-related distress and their potential mechanisms. Method: Informal caregivers of people with dementia (n = 157) recruited from 28 community mental health teams in six NHS Trusts across England completed questionnaires regarding psychosocial factors (relationship quality, competence, guilt, health-related quality of life in the caregiver and person with dementia, reactivity to behavioural and psychological symptoms in dementia [BPSD] and burden) and frequency of BPSD. Analyses of BPSD-related distress include hierarchical multiple regression, mediation, moderation and path analysis. Results: Caregiver psychosocial factors explained 56% of the variance in BPSD-related distress. After controlling for these factors, frequency of BPSD was not a significant predictor of BPSD-related distress. Caregiver reactivity to BPSD, burden, competence and relationship quality directly influenced BPSD-related distress. Guilt influenced distress indirectly via competence, burden and reactivity to BPSD. The final model accounted for 41% of the variance in BPSD-related distress and achieved a good fit to the data (χ 2 = 23.920, df = 19, p = 0.199). Conclusions: Caregiver psychosocial factors including sense of competence, guilt, burden and reactivity to BPSD contribute to BPSD-related distress. Tailored interventions for managing behaviour problems in family settings could focus on these factors associated with BPSD-related distress to minimise distress in families.
