The mobile connection : the cell phone's impact on society
Has the cell phone forever changed the way people communicate? The mobile phone is used for \"real time coordination while on the run, adolescents use it to manage their freedom, and teens \"text to each other day and night. The mobile phone is more than a simple technical innovation or social fad, more than just an intrusion on polite society. This book, based on world-wide research involving tens of thousands of interviews and contextual observations, looks into the impact of the phone on our daily lives. The mobile phone has fundamentally affected our accessibility, safety and security, coordination of social and business activities, and use of public places. Based on research conducted in dozens of countries, this insightful and entertaining book examines the once unexpected interaction between humans and cell phones, and between humans, period. The compelling discussion and projections about the future of the telephone should give designers everywhere a more informed practice and process, and provide researchers with new ideas to last years. *Rich Ling (an American working in Norway) is a prominent researcher, interviewed in the new technology article in the November 9 issue of the New York Times Magazine. *A particularly \"good read\", this book will be important to the designers, information designers, social psychologists, and others who will have an impact on the development of the new third generation of mobile telephones. *Carefully and wittily written by a senior research scientist at Telenor, Norway's largest telecommunications company, and developer of the first mobile telephone system that allowed for international roaming.

The role of information and communication technologies in mitigating carbon emissions: evidence from panel quantile regression
The objective of the study is to analyze the dynamic linkages between technology factors and carbon emission in a panel of 26 selected European countries from 2000 to 2017. The results of the panel fixed-effect regression model show the monotonic increasing function between agriculture technology and carbon emissions. In contrast, panel quantile regression confirmed the inverted U-shaped ‘Agriculture Technology Kuznets curve (ATKC)’ of carbon emissions at 30th quantile distribution to 80th quantile distribution with the turning points of 12,60,000 tractors to 9,68,000 tractors, respectively. The results further exhibit the negative relationship between high-technology exports and carbon emissions, as high-technology exports have a positive impact on environmental quality in order to reduce carbon emissions across countries. The relationship between ICT goods exports and carbon emissions is complimentary, while R&D expenditures have a negative relationship with carbon emissions in a given period. The study substantiates the ‘pollution haven hypothesis (PHH)’ that is controlled by trade liberalization policies. The telephone and mobile penetrations have a differential impact on carbon emissions in both of the prescribed statistical techniques, which needs fair economic policies in order to delimit carbon emissions through green ICT infrastructure. The results further exhibit the ‘material footprint’ that is visible at the earlier stages of economic development while it is substantially decreasing at the later stages to verify ‘environmental Kuznets curve (EKC)’ hypothesis with a turning point of US$45,700. Finally, the study shows the positive relationship between industry value-added and carbon emissions that sabotaged the process of green development across countries. The study concludes that green ICT infrastructure is imperative for sustainable production and consumption, and climate change protection with cleaner production techniques and environmental regulations that reshape the international policies towards sustained growth.

Introducing the North American project to evaluate soil health measurements
The North American Project to Evaluate Soil Health Measurements was initiated with the objective to identify widely applicable soil health measurements for evaluation of agricultural management practices intended to improve soil health. More than 20 indicators were chosen for assessment across 120 long‐term agricultural research sites spanning from north‐central Canada to southern Mexico. The indicators being evaluated include common standard measures of soil, but also newer techniques of visible and near‐infrared reflectance spectroscopy, a smart phone app, and metagenomics. The aim of using consistent sampling and analytical protocols across selected sites was to provide a database of soil health indicator results that can be used to better understand how land use and management has affected the condition of soil ecosystem provisioning for agricultural biomass production and water resources, as well as nutrient and C cycling. The objective of this paper is to provide documentation of the overall design, and methods being employed to identify soil health indicators sensitive across agricultural management practices, pedologies, and geographies.

Effectiveness of online and mobile telephone applications (‘apps’) for the self-management of suicidal ideation and self-harm: a systematic review and meta-analysis
Background
Online and mobile telephone applications (‘apps’) have the potential to improve the scalability of effective interventions for suicidal ideation and self-harm. The aim of this review was therefore to investigate the effectiveness of digital interventions for the self-management of suicidal ideation or self-harm.
Methods
Seven databases (Applied Science & Technology; CENTRAL; CRESP; Embase; Global Health; PsycARTICLES; PsycINFO; Medline) were searched to 31 March, 2017. Studies that examined the effectiveness of digital interventions for suicidal ideation and/or self-harm, or which reported outcome data for suicidal ideation and/or self-harm, within a randomised controlled trial (RCT), pseudo-RCT, or observational pre-test/post-test design were included in the review.
Results
Fourteen non-overlapping studies were included, reporting data from a total of 3,356 participants. Overall, digital interventions were associated with reductions for suicidal ideation scores at post-intervention. There was no evidence of a treatment effect for self-harm or attempted suicide.
Conclusions
Most studies were biased in relation to at least one aspect of study design, and particularly the domains of participant, clinical personnel, and outcome assessor blinding. Performance and detection bias therefore cannot be ruled out. Digital interventions for suicidal ideation and self-harm may be more effective than waitlist control. It is unclear whether these reductions would be clinically meaningful at present. Further evidence, particularly with regards to the potential mechanisms of action of these interventions, as well as safety, is required before these interventions could recommended.

Convergence in information and communication technology : strategic and regulatory considerations
This book is a compilation of two recently completed works on the convergence of information and communication technology (ICT) (Singh and Raja 2008, 2009). Since then, convergence, the eroding of boundaries among previously separate ICT services, networks, and business practices, has accelerated and deepened. At the time these reports were written, convergence was already a reality and was picking up pace in low-income countries, as in the rest of the world. Now, as this introduction summarizes, broadband networks are reaching deeper into previously unserved areas. The growing number of people connected to broadband networks are consuming, sharing, and creating new multimedia content and applications. And they are doing this on handheld and portable devices that are less costly and do more than before. All sorts of users, governments, businesses, individuals, and ICT firms, are looking to cut costs while capturing greater value. Taken together, these trends indicate that convergence is set to accelerate even through the ongoing global economic downturn. Countries that enable convergence through appropriate policy and regulatory responses will realize significant benefits in terms of expanded access, lower prices, and greater competition. Chapter two of this book focuses on the strategic implications of convergence and possible policy responses. Chapter three focuses on emerging regulatory practices facilitating multiple plays, or the provision of multiple services, such as voice telephony, broadcasting, and Internet access, by one operator over a single communications network, typically telephone or cable television but increasingly mobile and fixed wireless networks. The book concludes by presenting several best-practice principles for regulatory responses to multiple plays and, to some extent, to convergence more generally. Indeed, the main task for regulators is to remove artificial barriers and restrictions that are remnants of legacy regulation, thus clearing the way for market forces to play out, promoting the public interest, and leading to the realization of a range of benefits for users.

NutriNet: A Deep Learning Food and Drink Image Recognition System for Dietary Assessment
Automatic food image recognition systems are alleviating the process of food-intake estimation and dietary assessment. However, due to the nature of food images, their recognition is a particularly challenging task, which is why traditional approaches in the field have achieved a low classification accuracy. Deep neural networks have outperformed such solutions, and we present a novel approach to the problem of food and drink image detection and recognition that uses a newly-defined deep convolutional neural network architecture, called NutriNet. This architecture was tuned on a recognition dataset containing 225,953 512 × 512 pixel images of 520 different food and drink items from a broad spectrum of food groups, on which we achieved a classification accuracy of 86.72%, along with an accuracy of 94.47% on a detection dataset containing 130,517 images. We also performed a real-world test on a dataset of self-acquired images, combined with images from Parkinson’s disease patients, all taken using a smartphone camera, achieving a top-five accuracy of 55%, which is an encouraging result for real-world images. Additionally, we tested NutriNet on the University of Milano-Bicocca 2016 (UNIMIB2016) food image dataset, on which we improved upon the provided baseline recognition result. An online training component was implemented to continually fine-tune the food and drink recognition model on new images. The model is being used in practice as part of a mobile app for the dietary assessment of Parkinson’s disease patients.
