An Exploration of Intrusive Mobile Phone Behavior
Authors: Short Emma , McMurray Isabella
Published: June 2015

Technological advances in mobile phones, changing tariffs, and cultural and individual differences have influenced the explosion in communication between individuals through online applications with a mobile phone. Positive benefits include the ability to make contact anytime, anywhere. However, there are also drawbacks. Instant, remote access has opened the door to intrusive behaviors (also known as cyberstalking) by mobile devices. This article provides a brief overview of cyberstalking laws alongside a review of empirical studies exploring cyberstalking, drawing on the authors' own previous study and others in the field. Intrusive behavior is prevalent to the point of becoming a social norm despite recipients reporting being distressed; there is still a higher level of acceptance of online harassment than there is for offline harassment. Future research and interventions should focus on exploring the social norms of this behavior and raising awareness of the effect of unwanted contact by online, often mobile devices.
Homophily and Online Politics
Authors: Wallsten Kevin , Toteva Dilyana
Published: June 2015

The expansion of the Internet and the sudden popularity of Web 2.0 applications, such as blogs, YouTube, Twitter, and Facebook, raise important questions about the extent and consequences of homophilous sorting in online political discussions. In particular, there is growing concern that Internet users' ability to filter out alternative points of view will lead political discourse to become more polarized and fragmented along ideological lines. The decline of deliberative democracy and the breakdown of America's system of representative government, the story goes, will be the inevitable causalities of political discussions moving from in-person to online. Unfortunately, the empirical research in fields such as mass communication, political science, and sociology provides no hard and fast conclusions about the amount of online homophily in political discussions. This article details this conflicted body of research and points to some areas where future research may provide more insight into the intersection of online politics and homophilous sorting.
Students Hurting Students: Cyberbullying as a Mobile Phone Behavior
Authors: Conn Kathleen
Published: June 2015

While technology can be educationally motivating for students of all ages, technology can also be a cruel tool in the hands of youngsters and teens who do not yet understand the implications and ramifications of remote and potentially anonymous communication. Texting and talking on a mobile cell phone encourages more uninhibited discourse than would likely occur in face-to-face conversation because the texter or talker sees no visual cues that signal the response of the recipient of the communication. Technology-enabled verbal bullying behavior, or cyberbullying, can become especially vicious, even threatening. This chapter will examine the elements of cyberbullying as a misuse of technology and especially as a misuse of mobile phones, its prevalence, and some of the reasons students cyberbully. The article will also examine the potential legal issues involved in bullying and cyberbullying. Finally, the article will offer proposed solutions to the problem, including the responses and responsibilities of school personnel, families, and the students themselves.
Text Messaging in Social Protests
Authors: Chiluwa Innocent
Published: June 2015

This article gives a general overview of the roles of mobile phone in initiating and mobilizing social protests. It is argued that text messaging had been used to mobilize civil engagement and protests ever before the prevalence of modern social media. Drawing from different social and political contexts, this article also shows that text messaging has been used by protesters alongside Twitter and Facebook to achieve significant political change. It further chronicles major research literature in political protests and social media studies. The article proposes further research directions on how true it is that texting and social media do indeed achieve realistic political change, giving different sociopolitical contexts and unique situations of protesters. It examines the argument against cyber utopianism that contends that the assumed emancipatory roles of social media and text messaging can be misleading.
Generation Y and Mobile Marketing in India
Authors: Jain Varsha , Roy Subhadip
Published: June 2015

India holds the second top position in terms of size of the mobile market industry. Indians use their phone primarily to retrieve information, to educate themselves, for entertainment, and for communication. It is also noteworthy that a major chunk of these mobile phone users is Generation Y. They are tech savvy, keen for new technology, and have high income with high spending capacity. Different features of mobile phones such as Bluetooth, multimedia messaging, SMS, QR codes, and apps are frequently used by Generation Y. However, the problem with this generation is that they have a very short span of attention. In this paper, the authors explain the attitude of Generation Y in India towards the mobile applications and in-app advertising, as well as different interesting domains of mobile marketing in the context of India.
Mobile Phones Influence on Journalism Practice in Africa
Authors: Nassanga Goretti L. , Semujju Brian
Published: June 2015

This article reviews current research on mobile phone appropriation by journalists and how this has transformed journalism practice in Africa. Based on Marshall McLuhan's Medium theory, the article explores perspectives from various research studies on how the medium, or the mobile, is shaping media practice, guided by the concept of ‘technological determinism.' As Africa moves towards becoming part of the information society, the mobile or ‘The New Talking Drum of Everyday Africa' (De Bruijn et al., 2009), has become an essential multi-purpose tool for journalists. Several challenges in assessing the impact of mobiles on journalism that are peculiar to Africa are highlighted, including the digital divide that is translating into the mobile divide. Pointers are given for future research directions that should facilitate the harnessing of the potential of ‘mobiles 4 development,' thereby contributing to overall development in African countries.
Cognitive Phone for Sensing Human Behavior
Authors: Pei Ling , Guinness Robert , Kaistinen Jyrki
Published: June 2015

A boom of various sensor options gives a mobile phone the capability for sensing the social context and makes a mobile phone an attractive “cognitive” platform, which has great potential to model and cognize human behavior. A review of the history, current state, and future directions of the cognitive phone are outlined in this article. An implementation example of a cognitive phone is presented, and a Location-Motion-Context (LoMoCo) model is introduced, to combine personal location information and motion states to infer a corresponding context. Future possibilities of cognitive phones in behavior detection and change are outlined.
Impact of the Mobile Phone on Classical Radio
Authors: Barnes Brenda
Published: June 2015

Television was the first disruptive innovation that impacted radio. Radio adapted by changing its programming to disc-based music, which was less expensive to produce, and changing the revenue model from network advertising to local ads and national advertising. Mobile phones are being used increasingly for music, and since they are as portable and easy to use as radios, they are creating a new wave of disruptive innovation. Currently, radio revenues are holding strong, advertising across traditional and new media platforms is effective, and radio executives are creating apps and trying to activate the FM chip in mobile phones in order to ensure a place on the new platforms. Classical public radio has a slight advantage in that the Internet streaming radio services do not serve classical listeners as well; however, that could change. It will be necessary to monitor changes in technology use and advertising effectiveness to ensure that radio and classical radio remain competitive.
Mobile Games
Authors: Richardson Ingrid , Hjorth Larissa
Published: June 2015

This article provides a critical overview of mobile gaming, from discrete offline casual games to location-based, mixed reality, cross-platform, and urban games and, more recently, the array of downloadable playful and social applications for the touchscreen smartphone and handheld tablet or iPad. The discussion begins by casting mobile games as one of the most significant trajectories of an emerging app-based media ecology. The authors consider the way mobile gaming and play have become intrinsic to our everyday practices and challenge the distinction that is often made between casual and hardcore (or ‘real') gamers. The article then explores how location-based mobile games generate hybrid experiences of place and presence, requiring the player to integrate their own situated and embodied perception of the world with dynamic GPS-enabled information. Finally, the overview turns to the relation between mobile media and social media games—which include those mobile games and apps that embed social networking and sharing features into the game or games accessed and played through social networking services via a mobile device. On a broader scale—in terms of the impact of mobile games on our daily lives—the proliferation of mobile interfaces, games, and playful apps is playing a key role in what is termed the ‘lusory' or playful turn in culture.

As mobile phone technology has evolved and features and hardware have been added and enhanced, users now have the opportunity to access their mobile devices anytime and anywhere for a wide range of purposes, from taking photos and recording or viewing audio and video files to editing and sharing these files privately or through social networking websites. This article reports on the use of mobile phones to produce videos for educational purposes. The connection between video production and mobile learning is presented first, followed by the benefits of using mobile phones for video production. This article closes by identifying some concerns and suggestions identified in the literature in order to establish a path for further research. With the increasing practice of video sharing for personal, work, or social networking purposes, it is likely that video production will receive further attention from researchers as they continue to assess the educational potential of the video recording feature available on mobile devices.
Cell Phone Conversation and Relative Crash Risk
Authors: Young Richard A.
Published: June 2015

Two pioneering studies that examined cell phone billing records of people who had been in automobile crashes estimated that cell phone “use” while driving elevated crash risk by a factor of four relative to driving without cell phone use, a substantial increase. Cell phone “use” in these pioneering studies refers solely to cell phone conversation, because billing records contain no information about the visual-manual aspects of cell phone use. Recent research suggests that these pioneering studies overestimated the relative risk of cell phone conversation by a factor of seven due to two major biases. After adjustment for these biases, cell phone conversation does not increase crash risk beyond that of driving without a cell phone conversation, and may, in fact, reduce crash risk. The main reasons are driver self-regulation and reduced drowsiness, which fully compensate for the slight delays in brake response times caused by cell phone conversation.

Portable Social Groups
Authors: Auter Philip J. , Rudyk R. Brandon
Published: June 2015

Mobile phones today hold a high level of importance to a changing communication environment. These devices both loved and hated differ dramatically in there usage from young adults to their parents and older users. A variety of instrumental and ritualistic gratifications have been found for adolescent mobile phone use. Research has shown that usage patterns are constructed partially based on relationships within social groups. Studies of how the public feels – or ‘folk framing' – about mobile phones suggest that the average member of society, whether a mobile phone user or not, has mixed feelings about this liberating technology (Katz & Aakhus, 2002). Framed within a uses and gratifications theoretical foundation, this article reviews the literature that has shaped mobile phone communication theory and studies over the last decade.

Impacts from Tourism Development in Langkawi Island, Malaysia
Authors: Marzuki Azizan
Published: June 2015

Based on a study conducted in Langkawi Island, this chapter attempts to track the progress of tourism development of the island since 1986 until year 2004. Although the government and private sector had invested a lot of money in providing public infrastructure and facilities to boost the tourism industry in the island, no study had been conducted to relate tourism spending with the impact of these developments towards the local economy and socio-culture. Nevertheless, results from semi-structured interviews with local stakeholders involving hotel managers, government and non-government organizations representatives, resort and tourism developers and community leaders show two key issues regarding the benefits of tourism development and the costs of tourism development. The analysis also found that despite the limitation and development issues, the benefits of tourism development in Langkawi far outweighed the costs accrued to the local populace.
Eco-Cultural Tourism for Biodiversity Conservation and Sustainable Development of Remote Ecosystems in the Third World
Authors: Poyyamoli G.
Published: June 2015

Most of the remote areas such as mountains and islands are characterized by the features such as remoteness, fragility, endemism, and upland/lowland or island/mainland linkages, besides richer biodiversity and indigenous knowledge, thus attracting a large number of quality conscious tourists. However, conventional “top-down”, reactive and ad-hoc approaches and ill-conceived “development” activities such as infrastructure for mass tourism will destroy the very natural and cultural resource base on which the tourism thrives in these areas. These trends have led to the paradigm shifts towards community-based, participatory, and pro-active management strategies. Appropriate strategies for integrating biodiversity conservation and sustainable livelihoods by regenerating nature and culture for facilitating sustainable development of remote ecosystems in the third world are discussed in this chapter.
An Investigation of E-HRM Practices in Indian Tourism and Hospitality Industry
Authors: Chand Dhiman Mohinder
Published: June 2015

Since the 1980s, there has been a rapid shift towards the application of information technology (IT) for business processes. Information technology is recognised as a critical driver of transition of human resource management role from an administrative to a strategic business partner. This strategic role not only adds a valuable dimension to the HRM function but also changes the competencies demanded for the success of HR professionals. The purpose of this chapter is to identify most significant E-HRM practices adopted by the Indian hospitality industry. Data were collected from the HR managers of hospitality enterprises in India. A survey methodology was chosen because it was deemed to be the most efficient way of reaching a large number of respondents, whereas the data required facilitated the use of a mail-administered questionnaire with close-ended questions. A set of 33 E-HRM practices items was initially generated from a review of management research.
Ways of Applying Destination Management Concepts to the Development of Internal Tourism in Uzbekistan
Authors: Navruz-Zoda Bakhtiyor , Ibragimov Nutfillo
Published: June 2015

This chapter examines the role of the destination approach in the development of internal tourism in Uzbekistan. The trump-card of tourism in Uzbekistan is ancient cities like Tashkent, Samarkand, Shakhrisabz, Bukhara and Khiva. The chapter is focused on substantiation of destination model of tourism management, based on a junction of regional management and marketing theories. In order to reform the one-dimensional “package” system of tourism supply that operates in Uzbekistan to a multi-sided “integration” system it is recommended to run “creating destinations” policy in the tourism industry. That implies the creation process of integrated tourist destination based on organic combination of tourism supply and demand. The chapter describes seven stages of destination creating process: determination of purpose of visit in tourist location; selection of sights from destinations; clarification and analyzing destinations creating factors, explanation principles of creating destination; development criteria of creating destinations; creation of attractive destinations; arrangement of destination management system.
Human Resource Management in Indian Hospitality Industry
Authors: Chand Dhiman Mohinder , Kumar Amit
Published: June 2015

In the present era of globalization, human resources is the most important asset for any organization and a source of achieving competitive advantage. The theory, research, and practice of human resource management (HRM) has evolved considerably over the past century; experiencing a major transformation in practices within the most recent three decades. Today, HRM is regarded as the source of sustained competitive advantage for many organizations operating in a global economy, with no exception for the tourism and hospitality industry. While there is growing evidence that the practice of human resource management in the hospitality industry is characterized by informality, there is less evidence about the emerging theoretical and practical aspects of HRM. Thus, this chapter makes a modest attempt in the direction of building management concerns and advocacy for better HRM systems and practices in Indian hospitality industry.
The Role of Market Sentiment in Stock Price Movements
Authors: Sett Kiranjit , Mukhopadhyay Debabrata
Published: June 2015

In an efficient capital market, the prices of securities always fully reflect all available information implying that prices always reflect the fundamental values. When there is under reaction or over reaction to new information, competition among the arbitrageurs quickly brings the price of an asset back to its fair value. But, if the asymmetry of information about a stock is high and there is a ‘limit to arbitrage', sentiment of the noise traders is likely to influence the price of that stock. This chapter aims at studying the role of market sentiment, during the period which starts with June 2003 and ends with July 2011, in influencing the return from investment in small capitalization stocks listed on Indian stock exchanges. We have found the presence of ARCH (1) in the time series on returns. Market sentiment, rate of interest and inflation are found to have significant influence on return from investment in small capitalization stocks. The presence of month effects in returns from such stocks has also been detected.
Post Crisis Performance and Confidence of the Indian Economy
Authors: Bhattacharyya Rajib
Published: June 2015

The recent global financial crisis is viewed as a glaring example of limitless pursuit of deregulation of financial markets and failure of global corporate governance. Though the global economic slowdown had its epicenter in the US but its impact is being witnessed in all major economies of the world. The present chapter seeks to analyze the post crisis experience of the Indian economy as compared to the global economic performances, using various macroeconomic indicators as output, employment, inflation, current account balance, movement in real effective exchange rate and inflow of FDI. It is based on a statistical analysis using secondary time-series data and is based on the Exogenous Structural Break Model developed by Perron (1989). Finally it tries to highlight the confidence of the economic agents based on some well recognized confidence indices (for e.g. Business Confidence Index, Consumer Confidence Index, FDI Confidence Index etc.) during the post-crisis period.
Dimensions of Good Governance
Authors: Mandal Chhanda , Gupta Anita Chattopadhyay
Published: June 2015

Effectiveness of governance is realised through its responses to any financial crisis. This was put in question as the Great Recession affected the core economies severely. This study empirically investigated the relationship between accountability, corruption, and government effectiveness during the period 2002-2012. Our main purpose was to highlight the sizable gap that exists in the performance literature on cross-country studies especially against the changing economic world scenario. A comparison of the World Bank governance indicators between three countries chosen on the basis of income differentials and hence different adaptive characteristics of each country to the economic recession has been studied. The behavior of the governance indicators in the context of the world has been examined against the background of the shock that the depression had brought and the resilience factors embedded within the indicators in the face of the shocks were studied.
The Inter-Linkage between Governance and Poverty
Authors: Adhikary Maniklal , Sinha Dyuti
Published: June 2015

This chapter aims at assessing the impact of governance on the country's economic and human well-being in the selected South Asian countries. The study finds that for the countries-India, Pakistan, Bangladesh, Sri Lanka and Nepal, over the years 1990-2012, the growing rate of GDP per capita (PPP) and growing employment to population ratio has a significant negative impact on the Global Hunger Index as expected. Also the panel regression run for the eight SAARC countries over the period 2007-13 to find out the impact of each of the six governance indicators on the per capita GDP showed that political stability and absence of violence, government effectiveness and regulatory quality have very strong and significant role in augmenting the economic output besides the remaining indicators. The trends for each of the indicators across countries over time show that except Bhutan, none of the countries are exhibiting good performance of the governance indicators.
Globalization, Governance, and Food Security
Authors: Jana Sebak K. , Karmakar Asim K.
Published: June 2015

Food security is a major area of concern for the five nations that constitute BRICS. BRICS countries account for more than 40% of the world population and 25% of world GDP in PPP terms. Besides, these countries have a key role to play in the post-crisis global economy as producer of goods and services, receivers and exporters of capital, and/or consumer market on large potential. More importantly, these ones envisage ways to promote food security and food production in Third World countries by raising agricultural productivity and output via initiatives like the creation of basic agricultural information exchange system of these countries; enhancing investments in the food supply chain; developing a social safety net through conditional income transfer programmes for the poorest of the poor. In this context the present chapter examines the status of food security of BRICS economies in the context of globalization and governance and its implications thereof.
Effect of Recent Global Financial Crisis on South Asian Economy with Special Reference to India
Authors: Neogi Chiranjib
Published: June 2015

Most of the Asian countries were affected adversely for the recent global financial crisis, especially those economies whose growths are largely depended on the external trade. It has been observed over time and again that Indian economy has not been significantly harmed by the waves of global financial and economic crises because of its large domestic market, which can accommodate any external shock. During the phase of shrinking world demand of domestic goods and services, efforts to raise productivity and competitiveness helps countries to protect export market. This chapter investigates the dependence on the external market and the effect of global financial crisis on the trade structure of some Asian countries. Some detail studies will be done for India in respect of compositional changes and productivity and efficiency changes of different industries within manufacturing sector during pre and post crisis period. Efficiency and productivity will be analyzed using frontier model.
Factors Determining Foreign Direct Investment Inflow to Nigeria during Pre-Financial Crisis
Authors: Dinda Soumyananda
Published: June 2015

This chapter empirically investigates the determinants of foreign direct investment (FDI) to Nigeria during pre-financial crisis period 1970-2006. This study suggests that the endowment of natural resources, trade intensity, macroeconomic risk factors like inflation and exchange rates are significant determinants of FDI flow to Nigeria. The findings also suggest that in long run market size is not the significant factor for attracting FDI to Nigeria, it contradicts the existing literature. The author's results indicate that FDI flow to Nigeria is resource-seeking FDI. Results also suggest that trading partner like the UK in North-South (N - S) and China in South-South (S - S) trade relation have strong influence on Nigeria's natural resource outflow.
FDI, Urbanization, and Economic Growth Linkages in India and China
Authors: Patra Sudhakar
Published: June 2015

The rapid urbanization and economic growth during new round of globalization is largely due to the flows of Foreign Direct Investment (FDI). In this context the objectives of this chapter is to analyze the causality and linkage among urbanization, GDP and foreign direct investment in China and India with the help of secondary data from 1979 to 2012. It focuses on determinants and pattern of FDI flow in China and India. The study observes a significant positive correlation between urbanization and flow of FDI to a particular region both in China and India. The rate of growth of FDI is significantly influenced by rate of growth of urban population at 10 per cent level of significance and by rate of growth of per capita GDP at 1 percent level of significance. The study also highlights the causality and linkage between urbanization and FDI inflow with evidences from China and India.
The New Economic Environment to Manage Resources in Cloud Computing
Authors: Bouamama Samah , Belalem Ghalem
Published: June 2015

The Clouds have changed the way services are delivered to companies. The attractiveness of the Clouds comes from the (efficacy) effective gains (cost, performance, availability, fault tolerance...) and agility of enterprise applications and services. The computer infrastructure is becoming a supply chain services. Existing systems of Clouds do not support advanced mechanisms for the optimal trade applications across different Clouds. In this study, the authors proposed an environment consisting of a set of customers with a budget and a number of Cloudlet to process. Before starting the auction procedure, they fit in their separate group, previously formed according to a certain criteria, by paying a registration fee that will be cashed at a local bank in each Club. If a customer does not have enough budget (client in crisis) to satisfy their needs, they can make a bank loan. In this work, the authors propose the way to satisfy Clubs in terms of quality of processing cloudlets (Tasks) for each member of a Club, while minimizing their cost and their time of processing, and the way to integrate the principle of Auction Clubs in CloudSim simulator.

Development of a training programme for primary care providers to counsel patients with risky lifestyle behaviours in South Africa
Authors: Malan Zelra , Mash Bob , Everett-Murphy Kathy
Published: June 2015

Background: We are facing a global epidemic of non-communicable disease (NCDs), which has been linked with four risky lifestyle behaviours. It is recommended that primary care providers (PCPs) provide individual brief behaviour change counselling (BBCC) as part of everyday primarycare, however currently training is required to build capacity. Local training programmes are not sufficient to achieve competence.Aim: This study aimed to redesign the current training for PCPs in South Africa, around a new model for BBCC that would offer a standardised approach to addressing patients’ risky lifestyle behaviours.Setting: The study population included clinical nurse practitioners and primary care doctors in the Western Cape Province.Methods: The analyse, design, develop, implement and evaluate (ADDIE) model provided a systematic approach to the analysis of learning needs, the design and development of the training programme, its implementation and initial evaluation.Results: This study designed a new training programme for PCPs in BBCC, which was based on a conceptual model that combined the 5As (ask, alert, assess, assist and arrange) with a guiding style derived from motivational interviewing. The programme was developed as an eight-hour training programme that combined theory, modelling and simulated practice with feedback, for either clinical nurse practitioners or primary care doctors.Conclusion: This was the first attempt at developing and implementing a best practice BBCC training programme in our context, targeting a variety of PCPs, and addressing different risk factors.

O presente estudo objetivou estimar parâmetros genéticos e a variabilidade entre e dentro de procedências, para caracteres silviculturais em um teste de procedências e progênies de Handroanthus vellosoi (Toledo) Mattos estabelecido na Estação Experimental de Luiz Antônio (SP). O teste foi instalado no delineamento experimental de blocos de famílias compactas, com duas procedências (alocadas nas parcelas), seis repetições e sub-parcelas lineares de cinco plantas, totalizando 35 progênies. O ensaio foi mensurado para os caracteres diâmetro à altura do peito, altura de planta, volume cilíndrico, forma do fuste e sobrevivência aos 24 anos de idade. Diferenças significativas entre procedências foram observadas apenas para o caráter forma do fuste. Pela análise de deviance foram detectadas diferenças significativas para o efeito de progênies para análise conjunta das procedências  (população experimental), sugerindo que esta tem alta  variação genética e indicando possibilidade de  melhoramento genético pela seleção das melhores progênies. A estimativa de herdabilidade em nível individual e média de progênies variaram de baixa a moderada (26% para DAP, 32% para altura, 24% para volume cilíndrico, 27% para forma do fuste e 46% para sobrevivência), confirmando a possibilidade de melhoramento genético por seleção e que as procedências tem potencial para responder à pressão de seleção natural.

Published: June 2015

Abstract. Nitrogen Dioxide is both a primary pollutant with direct health effects and a key precursor of the secondary pollutant ozone. This paper reports on the development, characterisation and test flight of the Atmospheric Nitrogen Dioxide Imager (ANDI) remote sensing system. The ANDI system includes an imaging (UV)-vis grating spectrometer able to capture scattered sunlight spectra for the determination of tropospheric nitrogen dioxide (NO2) concentrations by way of DOAS slant column density and vertical column density measurements. Results are shown for an ANDI test flight over Leicester City in the UK. Retrieved NO2 columns at a surface resolution of 80 m x 20 m revealed hot spots in a series of locations around Leicester City, including road junctions, the train station, major car parks, areas of heavy industry, a nearby airport (East Midlands) and a power station (Ratcliffe-on-Soar). In the city centre the dominant source of NO2 emissions was identified as road traffic, contributing to a background concentration as well as producing localised hot spots. Quantitative analysis revealed a significant urban increment over the city centre which increased throughout the flight.

Published: June 2015

Abstract. The stable isotope composition of benthic sponge spicule silica is a potential source of palaeoceanographic information about past deep seawater chemistry. The silicon isotope composition of spicules has been shown to relate to the silicic acid concentration of ambient water, although existing calibrations do exhibit a degree of scatter in the relationship. Less is known about how the oxygen isotope composition of sponge spicule silica relates to environmental conditions during growth. Here, we investigate the vital effects on silica, silicon and oxygen isotope composition in a carnivorous sponge, Asbestopluma sp., from the Southern Ocean. We find significant variations in silicon and oxygen isotopic composition within the specimen that are related to unusual spicule silicification. The largest variation in both isotope systems was associated with the differential distribution of an unconventional, hypersilicified spicule type (desma) along the sponge body. The absence an internal canal in the desmas suggests an unconventional silicification pattern leading to an unusually heavy isotope signature. Additional internal variability derives from a systematic offset between the peripheral skeleton of the body having systematically a higher isotopic composition than the internal skeleton. A simplified silicon isotope fractionation model, in which desmas were excluded, suggests that the lack of a system for seawater pumping in carnivorous sponges favours a low replenishment of dissolved silicon within the internal tissues, causing kinetic fractionation during silicification that impacts the isotope signature of the internal skeleton. Analysis of multiple spicules should be carried out to "average out" any artefacts in order to produce more robust downcore measurements.

Abstract. A new anisotropic hr-adaptive mesh technique has been applied to modelling of multiscale transport phenomena, which is based on a discontinuous Galerkin/control volume discretization on unstructured meshes. Over existing air quality models typically based on static-structured grids using a locally nesting technique, the advantage of the anisotropic hr-adaptive model has the ability to adapt the mesh according to the evolving pollutant distribution and flow features. That is, the mesh resolution can be adjusted dynamically to simulate the pollutant transport process accurately and effectively. To illustrate the capability of the anisotropic adaptive unstructured mesh model, three benchmark numerical experiments have been setup for two-dimensional (2-D) transport phenomena. Comparisons have been made between the results obtained using uniform resolution meshes and anisotropic adaptive resolution meshes.
On the infinitely-stable rotational mechanism using the off-axis rotation of a bistable translational mechanism
Authors: Hao G. , Mullins J.
Published: June 2015

Abstract. Different from the prior art concentrating on the primary translation of bistable translational mechanisms this paper investigates the off-axis rotation behaviour of a bistable translational mechanism through displacing the guided primary translation at different positions. Moment-rotation curves obtained using the nonlinear finite element analysis (FEA) for a case study show the multiple stable positions of the rotation under each specific primary motion, suggesting that an infinitely-stable rotational mechanism can be achieved by controlling the primary motion. In addition, several critical transition points have been identified and qualitative testing has been conducted for the case study.

Abstract. Hydrogeochemistry of 10 hot springs in the Kangding district was investigated by analyzing cation and anion concentrations in the spring water. The water samples were collected in the 5 days after the Lushan MS = 7.0 earthquake, which occurred on 20 April 2013. The spring waters are classified into seven chemical types based on their hydrochemical compositions. Compared with hydrochemical data before the Lushan earthquake, concentrations of Ca2+, HCO3- and total dissolved solid (TDS) in water samples from the Guanding, Erdaoqiao, Gonghe, Erhaoying, Tianwanhe and Caoke springs significantly increased, which may be the result of a greater increase in groundwater from carbonate rocks, and water–carbonate rock interactions, enhanced by the increment of CO2. Concentrations of Na+, Cl- and SO42- in water samples from the Guanding, Zheduotang, Xinxing and Gonghe springs decreased, indicating a dilution of shallow waters. Concentrations of Na+ and SO42- in water samples from the Erhaoying spring water increased, which may be attributed to water–granite interactions enhanced by H2S. The results indicated that hydrochemical components of spring water could be used as an effective indicator for earthquakes.

Presentamos un estudio sobre redes sociales en la universidad y las posibilidades de mejora que ofrecen en la formación inicial de los futuros maestros. Se ha integrado una red social en el programa de estudio de Grado de Magisterio de la Universidad Autónoma de Madrid y se ha registrado el uso que hacen de ella los estudiantes y el impacto que estas tecnologías tienen en su actividad académica y su socialización. El formato elegido es el de red vertical o red propia, que ofrece posibilidades de gestión y seguridad adaptables a los requerimientos de los docentes. Se ha llevado a cabo un estudio de caso en una red social vertical propia con tres grupos de estudiantes de Grado de Magisterio (futuros docentes) siguiendo un proceso de recogida sistemática de datos. Como comprobaremos, su uso está muy extendido como elemento de comunicación social y ofrece mejoras en su aplicación académica desde el punto de vista de la interacción educativa y la motivación formativa. Pero la integración que tiene en su formación actual es pequeña en relación a las posibilidades y aplicaciones que tiene en otros campos.

En la actualidad, la integración de redes sociales educativas está adquiriendo un papel fundamental, para la mejora de los procesos de Enseñanza-Aprendizaje (E-A) en el ámbito universitario. El presente artículo sintetiza las aportaciones más relevantes recogidas a través de un estudio descriptivo, centrado en las percepciones del alumnado mediante la administración de un cuestionario y grupos de discusión, inmersos en la red educativa UGR-John Moores, como experiencia de investigación innovadora en la enseñanza  universitaria. El principal objetivo del estudio es conocer el uso e integración de esta red social y educativa, y valorar las posibilidades del aprendizaje colaborativo, para indagar y mejorar las acciones innovadoras desarrolladas en las nuevas metodologías docentes, abordadas en estas dos instituciones universitarias. Entre las contribuciones más destacables encontramos que la utilización de la red UGR/John Moores ha tenido una gran aceptación entre el alumnado, considerando la plataforma como un elemento facilitador para su aprendizaje, capaz de motivarle, generar y compartir sistemáticamente información, aumentando con todo ello, su entorno personal de aprendizaje (PLE). Sin embargo, es preciso incorporar una serie de mejoras respecto a la planificación docente con la integración de las TIC (acción tutorial), así como actualizar la formación del alumnado en uso de herramientas tecnológicas.

El propósito de este trabajo es de identificar y analizar los factores que inciden en el uso de las TIC en los procesos de enseñanza-aprendizaje en el nivel 5to de primaria en una escuela colombiana y plantear una estrategia de mejoramiento en su implementación. Se utilizó un enfoque cualitativo y se recolectó la información mediante entrevistas, observaciones y revisión de documentos. Los participantes fueron estudiantes y docentes del 5to grado, así como personal directivo de una escuela pública de nivel primaria, quienes brindaron sus opiniones acerca del uso de las TIC en su centro escolar. Entre los factores que inciden en la aplicación de herramientas tecnológicas en el ámbito escolar, se identificó la capacitación, la disponibilidad de recursos y el apoyo institucional. Como resultado, se encontró que todos los participantes reconocen los beneficios de las TIC, especialmente los estudiantes, sin embargo se necesita reforzar la capacitación y el apoyo de autoridades superiores.
