Since the target of burglars is generally the property of the inhabitant, it is crucial to accurately measure potential victims when analyzing burglaries, especially in small areas. Previous studies on burglary are mostly based on large units such as census tracts or communities. One of the difficulties is the measurement of the potential victims of burglary at the mesoscale. We compare the measuring effects of census population, census households, nighttime mobile phone users, and nighttime social media, such as the Tencent regional heatmap (TRH), on potential victims of burglary on 150 m × 150 m grids. Based on the rational choice theory, and controlling for the potentially confounding effects of risks and cost, we show that the TRH performed best, followed by census households and census population, and phone users performed poorly. The best-performing time period for TRH data was 3:00–5:00 am on weekends. These findings could lead to an improved measurement of potential victims of burglary at the mesoscale, and could provide scientific insight for crime prevention.

Purpose Recently, reverse logistics (RL) has become more prominent due to growing environmental concerns, social responsibility, competitive advantage and high efficiency by customers because of the expansion of product selection and shorter product life cycle. However, effective implementation of RL results in some direct advantages, the most important of which is winning customer satisfaction that is vital to a firm’s success. Therefore, paying attention to customer feedback in supply chain and logistics processes has recently increased so that manufacturers have decided to transform their RL into customer-centric RL. Hence, this paper aims to identify the features of a mobile phone which affect consumer purchasing behaviour and to analyse the interrelationship among them to develop a framework for customer-centric RL. These features are studied based on website analysis of several mobile phone manufacturers. The special focus of this paper is on social media data (Twitter) in an attempt to help the decision-making process in RL through a big data analysis approach. Design/methodology/approach A portfolio of mobile phone features that affect consumer’s mobile phone purchasing decisions has been taken from website analysis by several mobile phone manufacturers to achieve this objective. Then, interrelationships between the identified features have been established by using big data supplemented with interpretive structural modelling (ISM). Apart from that, cross-impact matrix multiplication, applied to classification analysis, was carried out to graphically represent these features based on their driving power and dependence. Findings During the study, it has been observed from the ISM that the chip (F5) is the most significant feature that affects customer’s buying behaviour; therefore, mobile phone manufacturers realize that this is to be addressed first. Originality/value The focus of this paper is on social media data (Twitter) so that experts can understand the interaction between mobile phone features that affect consumer’s decisions on mobile phone purchasing by using the results.

Background: Social media data may be used to shed light on how engaged the general public is in conversations surrounding elevated blood pressure (BP) as an important health problem. Methods: We gathered Twitter data from 1/1/2016 to 11/23/2019 using the ‘TweetScraper’ program (https://github.com/jonbakerfish/TweetScraper). We scraped tweets with content related to BP and, to generate comparator data, we similarly collected tweets related to allergies during the same time period. We then plotted the number of tweets over time (in days) for each health topic and compared the between-group frequency of tweets over time. Results: We observed that the frequency of tweets related to BP was consistently lower than that related to allergy, notwithstanding lower rates of allergy related tweets during the non-peak allergy seasons ( Figure ). The number of tweets related to BP never exceeded those related to allergy, per month, but there were single day anomalies: BP tweets exceeded allergy tweets by 78% on 11/13/2017 and by 96% on 11/14/2027, following the release of updated hypertension guidelines. Conclusions: We demonstrate both the feasibility and utility of using social media data to assess the general public’s interest level in certain health topics over time. We found persistently lower levels of engagement around elevated BP (asymptomatic but conferring high mortality risk) compared to allergies (symptomatic but conferring low mortality risk) despite their similarly wide prevalence. As popular social media methods of communication evolve, so will the challenges and opportunities related to harnessing these data as part of efforts to improve public health.
