The purpose of this paper is to contribute to the debate on blockchain (BC) adoption for preventing counterfeiting by investigating BC systems where different options for BC feeding and reading complement the use of BC technology. By grounding on the situational crime prevention, this study analyses how BC systems can be designed to effectively prevent counterfeiting.

This is a multiple-case study of five Italian wine companies using BC to prevent counterfeiting.

This study finds that the desired level of upstream/downstream counterfeiting protection that a brand owner intends to guarantee to customers through BC is the key driver to consider in the design of BC systems. The study identifies which variables are relevant to the design of feeding and reading processes and explains how such variables can be modulated in accordance with the desired level of counterfeiting protection.

The cases investigated are Italian companies within the wine sector, and the BC projects analysed are in the pilot phase.

The study provides practical suggestions to address the design of BC systems by identifying a set of key variables and explaining how to properly modulate them to face upstream/downstream counterfeiting.

This research applies a new perspective based on the situational crime prevention approach in studying how companies can design BC systems to effectively prevent counterfeiting. It explains how feeding and reading process options can be configured in BC systems to assure different degrees of counterfeiting protection.

In this study, the authors report visitors' and personnel's safety experiences and concerns in order to understand the safety conditions of a library.

The analysis is based on answers from a small sample survey of library visitors, interviews with the personnel and incidents recorded in a library in Stockholm the capital of Sweden.

Dealing with visitors under influence of drugs/alcohol or feeling intimidated by groups of young individuals are examples of situations in which the staff feel most unsafe. Visitors declare witnessing problems of public disturbance and disorderly conduct, fights and other types of aggression. Although the vast majority of visitors declare feeling safe in the library, their perceptions vary according to the library's environment and their individual characteristics, including their previous victimization.

The study is novel because it indicates the importance of the environment to ensure the safety conditions of the library for both visitors and staff. Finally, research on safety in libraries is often from North America and Western European contexts, while this study contributes to the international literature by illustrating libraries in a Nordic European context.

The study indicates that more social control, both formal and informal, is at the top of the list of recommendations for visitors. Among personnel, recommendations include the need for cooperation with other local actors to solve problems in surrounding areas as well as better education for librarians in dealing with the current safety challenges of libraries as multifunctional public facilities.

Combine visitors' and personnel's safety experiences to better understand the safety conditions of a public library.

The purpose of this paper is to use an evaluation of a micro-place-based hot-spot policing implementation to highlight the potential issues raised by data quality standards in the recording and measurement of crime data and police officer movements.

The study focusses on an area of London (UK) which used a predictive algorithm to designate micro-place patrol zones for each police shift over a two-month period. Police officer movements are measured using GPS data from officer-worn radios. Descriptive statistics regarding the crime data commonly used to evaluate this type of implementation are presented, and simple analyses are presented to examine the effects of officer patrol duration (dosage) on crime in micro-place hot-spots.

The results suggest that patrols of 10-20 minutes in a given police shift have a significant impact on reducing crime; however, patrols of less than about 10 minutes and more than about 20 minutes are ineffective at deterring crime.

Due to the sparseness of officer GPS data, their paths have to be interpolated which could introduce error to the estimated patrol dosages. Similarly, errors and uncertainty in recorded crime data could have substantial impact on the designation of micro-place interventions and evaluations of their effectiveness.

This study is one of the first to use officer GPS data to estimate patrol dosage and places particular emphasis on the issue of data quality when evaluating micro-place interventions.
