How green is your smartphone?
Every day we are inundated by propaganda that claims life will be better once we are connected to digital technology. Poverty, famine, and injustice will end, and the economy will be 'green'. All anyone needs is the latest smartphone. In this succinct and lively book, Maxwell and Miller take a critical look at contemporary gadgets and the systems that connect them, shedding light on environmental risks. Contrary to widespread claims, consumer electronics and other digital technologies are made in ways that cause some of the worst environmental disasters of our time - conflict-minerals extraction, fatal and life-threatening occupational hazards, toxic pollution of ecosystems, rising energy consumption linked to increased carbon emissions, and e-waste.

Mining Google and Apple mobility data: temporal anatomy for COVID-19 social distancing
We employ the Google and Apple mobility data to identify, quantify and classify different degrees of social distancing and characterise their imprint on the first wave of the COVID-19 pandemic in Europe and in the United States. We identify the period of enacted social distancing via Google and Apple data, independently from the political decisions. Our analysis allows us to classify different shades of social distancing measures for the first wave of the pandemic. We observe a strong decrease in the infection rate occurring two to five weeks after the onset of mobility reduction. A universal time scale emerges, after which social distancing shows its impact. We further provide an actual measure of the impact of social distancing for each region, showing that the effect amounts to a reduction by 20–40% in the infection rate in Europe and 30–70% in the US.

Mobile Phone–Based Telemedicine Practice in Older Chinese Patients with Type 2 Diabetes Mellitus: Randomized Controlled Trial
Previous studies on telemedicine interventions have shown that older diabetic patients experience difficulty in using computers, which is a barrier to remote communication between medical teams and older diabetic patients. However, older people in China tend to find it easy to use mobile phones and personal messaging apps that have a user-friendly interface. Therefore, we designed a mobile health (mHealth) system for older people with diabetes that is based on mobile phones, has a streamlined operation interface, and incorporates maximum automation.
The goal of the research was to investigate the use of mobile phone-based telemedicine apps for management of older Chinese patients with type 2 diabetes mellitus (T2DM). Variables of interest included efficacy and safety.
A total of 91 older (aged over 65 years) patients with T2DM who presented to our department were randomly assigned to one of two groups. Patients in the intervention group (n=44) were provided glucometers capable of data transmission and received advice pertaining to medication, diet, and exercise via the mHealth telemedicine system. Patients assigned to the control group (n=47) received routine outpatient care with no additional intervention. Patients in both groups were followed up at regular 3-month intervals.
After 3 months, patients in the intervention group showed significant (P<.05) improvement in postprandial plasma glucose level. After 6 months, patients in the intervention group exhibited a decreasing trend in postprandial plasma glucose and glycated hemoglobin levels compared with the baseline and those in the control group (P<.05).
Mobile phone-based telemedicine apps help improve glycemic control in older Chinese patients with T2DM.

Effect of restricting bedtime mobile phone use on sleep, arousal, mood, and working memory: A randomized pilot trial
This study aimed to assess the effects of restricting mobile phone use before bedtime on sleep, pre-sleep arousal, mood, and working memory.
Thirty-eight participants were randomized to either an intervention group (n = 19), where members were instructed to avoid using their mobile phone 30 minutes before bedtime, or a control group (n = 19), where the participants were given no such instructions. Sleep habit, sleep quality, pre-sleep arousal and mood were measured using the sleep diary, the Pittsburgh sleep quality index, the Pre-sleep Arousal Scale and the Positive and Negative Affect Schedule respectively. Working memory was tested by using the 0-,1-,2-back task (n-back task).
Restricting mobile phone use before bedtime for four weeks was effective in reducing sleep latency, increasing sleep duration, improving sleep quality, reducing pre-sleep arousal, and improving positive affect and working memory.
Restricting mobile phone use close to bedtime reduced sleep latency and pre-sleep arousal and increased sleep duration and working memory. This simple change to moderate usage was recommended to individuals with sleep disturbances.

Where are you?
This book sheds light on the most philosophically interesting of contemporary objects: the cell phone. \"Where are you?\"--a question asked over cell phones myriad times each day--is arguably the most philosophical question of our age, given the transformation of presence the cell phone has wrought in contemporary social life and public space. Throughout all public spaces, cell phones are now a ubiquitous prosthesis of what Descartes and Hegel once considered the absolute tool: the hand. Their power comes in part from their ability to move about with us--they are like a computer, but we can carry them with us at all times--in part from what they attach to us (and how), as all that computational and connective power becomes both handy and hand-sized. Quite surprisingly, despite their name, one might argue, as Ferraris does, that cell phones are not really all that good for sound and speaking. Instead, the main philosophical point of this book is that mobile phones have come into their own as writing machines--they function best for text messages, e-mail, and archives of all kinds. Their philosophical urgency lies in the manner in which they carry us from the effects of voice over into reliance upon the written traces that are, Ferraris argues, the basic stuff of human culture. Ontology is the study of what there is, and what there is in our age is a huge network of documents, papers, and texts of all kinds. Social reality is not constructed by collective intentionality; rather, it is made up of inscribed acts. As Derrida already prophesized, our world revolves around writing. Cell phones have attached writing to our fingers and dragged it into public spaces in a new way. This is why, with their power to obliterate or morph presence and replace voice with writing, the cell phone is such a philosophically interesting object.

Smartphone-based home care model improved use of cardiac rehabilitation in postmyocardial infarction patients: results from a randomised controlled trial
Objective Cardiac rehabilitation (CR) is pivotal in preventing recurring events of myocardial infarction (MI). This study aims to investigate the effect of a smartphone-based home service delivery (Care Assessment Platform) of CR (CAP-CR) on CR use and health outcomes compared with a traditional, centre-based programme (TCR) in post-MI patients. Methods In this unblinded randomised controlled trial, post-MI patients were randomised to TCR (n=60; 55.7±10.4 years) and CAP-CR (n=60; 55.5±9.6 years) for a 6-week CR and 6-month self-maintenance period. CAP-CR, delivered in participants’ homes, included health and exercise monitoring, motivational and educational material delivery, and weekly mentoring consultations. CAP-CR uptake, adherence and completion rates were compared with TCR using intention-to-treat analyses. Changes in clinical outcomes (modifiable lifestyle factors, biomedical risk factors and health-related quality of life) across baseline, 6 weeks and 6 months were compared within, and between, groups using linear mixed model regression. Results CAP-CR had significantly higher uptake (80% vs 62%), adherence (94% vs 68%) and completion (80% vs 47%) rates than TCR (p<0.05). Both groups showed significant improvements in 6-minute walk test from baseline to 6 weeks (TCR: 537±86–584±99 m; CAP-CR: 510±77–570±80 m), which was maintained at 6 months. CAP-CR showed slight weight reduction (89±20–88±21 kg) and also demonstrated significant improvements in emotional state (K10: median (IQR) 14.6 (13.4–16.0) to 12.6 (11.5–13.8)), and quality of life (EQ5D-Index: median (IQR) 0.84 (0.8–0.9) to 0.92 (0.9–1.0)) at 6 weeks. Conclusions This smartphone-based home care CR programme improved post-MI CR uptake, adherence and completion. The home-based CR programme was as effective in improving physiological and psychological health outcomes as traditional CR. CAP-CR is a viable option towards optimising use of CR services.
