The prevention of mobile phone theft: a case study of crime as pollution; rational choices and consumer demand.

This thesis makes two contributions to environmental criminology. The first contribution is a rational choice event model for mobile phone thieves. This is based on interviews with 40 mobile phone thieves. In addition, the deterrent effects of 23 designs of phone are assessed. Comparisons are made between the responses of offenders and non-offenders; and between experienced offenders and less experienced offenders. The results show that mobile phone thieves make discerning choices about which model of phone to steal at the point of theft. The factors affecting handset choice reflect Clarke s (1999) CRAVED characteristics. Mobile phone thieves are differentially deterred by a variety of design solutions, the most effective of which reduce the resale value of stolen handsets. In contrast with offenders, non-offenders are more easily deterred, and statistically significantly more deterred for five of the 23 designs presented in this thesis; do not appreciate the importance of resale value; and are not so aware of the possibilities for circumventing or neutralising security technology. The differences between offender and non-offender responses mean that offenders are arguably best placed to assess product use and misuse in the process of designing-out crime. The second contribution of this thesis is a Mobile Phone Theft Index which controls for phone availability in the absence of handset sales data. Mobile phone theft is arguably a form of pollution (Roman and Farrell, 2002) and can, therefore, be controlled using traditional pollution control instruments (Farrell and Roman, 2006). Informing the public of their risk of victimisation according to handset ownership would make security a marketable aspect of handset design, incentivising industry to decrease theft rates. Industry action to date shows evidence of obstructionism and pre-regulatory initiatives (Newman, 2004) meaning that a novel instrument such as the Index is necessary to alter the current status quo where industry costs UK society an estimated £1.2 billion per year (Mailley and Farrell, 2006)

Offending users: designing-in deterrence with mobile telephones

This paper describes research relating to the design semantics of desirable products and the crime of theft. The methods employed range from the review of existing designs of mobile phones and associated systems and technologies, the perception of crime from a student designer's viewpoint and, importantly, the opinions of young offenders about proposed design solutions. We developed conceptual designs in consultation with the Mobile Data Association and these were reviewed by a sample of groups of young offenders and 'non-offender' consumers of similar age, to reflect the different user perspectives. The conclusions reveal differences between offenders and non-offenders in their perceptions of the deterrent effect of different design solutions. It is suggested that the research offers insight into the use of empathic strategies in the design of frequently stolen 'hot products'

The crime drop and the security hypothesis

Major crime drops were experienced in the United States and most other industrialised countries for a decade from the early to mid-1990s. Yet there is little agreement over explanation or lessons for policy. Here it is proposed that change in the quantity and quality of security was a key driver of the crime drop. From evidence relating to vehicle theft in two countries it is concluded that electronic immobilisers and central locking were particularly effective. It is suggested that reduced car theft may have induced drops in other crime including violence. From this platform a broader security hypothesis, linked to routine activity and opportunity theory, is outlined

Bring on the safety razr: the top-10 stolen mobile phones

Mobile phone theft and robberies are almost as ubiquitous as the devices themselves

Progress and prospects in the prevention of mobile phone theft

Mobile phone ownership continues to be a driver of theft and robbery in the UK. Several years of news headlines such as “Mobile Phones and iPods fuel rise in Muggings” ((2006) Independent, February 27,) suggest that the problem may be getting worse rather than better. Whether this is true probably depends on what is measured. It is likely that total crimes have remained stable or increased at the same time as risk-per-phoneowner has decreased. The latest Oftel figures show that in 2005-6, the UK’s mobile phone subscriptions exceeded the population for the first time, having doubled in the last five or six years. The country being awash with mobile phones, stealing them is like shooting the proverbial fish in a barrel. We argue below that progress has been made in tackling mobile phone theft and that this is not incompatible with an increase in the problem, which would have been even greater without the measures taken to date. There may be a case for cautious optimism – but only if efforts to prevent mobile phone theft continue to be at least as persistent, innovative and adaptable as the thieves themselves to the point where the problem is stabilized and diminishes thereafter. Government, police and the mobile industry, working together, have a technological and geo-political advantage over offenders that, with a lot of skill and dogged determination, could yield absolute crime reductions in the future. What follows reviews some of the progress to date in tackling mobile phone theft and suggests this should form a platform for an expanded crime prevention effort

IN SAFE HANDS: A Review of Mobile Phone Anti-theft Designs

Anti-theft designs relating to mobile phones are reviewed. The physical and electronic design of handsets includes visual deterrents, owner-identification, and handset tracking options. The systems design of phone networks includes the blacklisting of stolen phones. Other measures include biometric-locking of handsets, and designs that encourage ‘safe’ phone use and transportation. Characteristics that promote anti-theft designs are proposed and form the acronym ‘IN SAFE HANDS’: identifiable, neutral, seen, attached, findable, executable, hidden, automatic, necessary, detectable, and secure. The set of characteristics is presented as a heuristic device to aid designing-out crime from frequently stolen electronic goods

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries

© 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
