Abstract

Purpose

The purpose of this paper is to propose a methodological approach to increase the clearance rate of cold cases in The Netherlands and to contribute to the development of intelligence-driven criminal investigations in general police practice and within cold case investigations in particular.

Design/methodology/approach

This proposal is based on practical investigative experience and academic knowledge.

Findings

Reconstructing scenarios helps convert cold case information into intelligence, which is beneficial to law enforcement agencies in terms of time, resources and prioritising cold cases. Intelligence contributes to the formulation of more effective queries and to a more efficient adaptation of new and existing investigation methods, leading to a higher cold case clearance rate. Moreover, scenario reconstruction creates a link between intelligence and investigation, i.e. between science and practice, which adds to the further development of intelligence-driven investigations.

Practical implications

When carrying out scenario reconstructions, practical implications are expected, as intelligence products are currently not or barely used in practice and science is not yet embedded in the investigational practice.

Originality/value

To move from scenario reconstruction to intelligence-driven criminal investigation, the gap between science and the investigational practice needs to be bridged by persons familiar with both. This study hopes to provide the necessary and relevant impetus to this dialogue.

Abstract

Purpose

Traditional crime linkage studies on serial sexual assaults have relied predominantly on a binary crime linkage approach that has yielded successful results in terms of linkage accuracy. Such an approach is a coarse reflection of reality by focussing mainly on the outcome of an offence, neglecting the forceful differences due to the intricate offender-victim interaction. Only few researchers have examined sexual assaults through the lens of a sequence analysis framework. This paper aims to present the first empirical test of offence sequence-based crime linkage, moving beyond exploratory analyses.

Design/methodology/approach

Offence accounts from 90 serial sexual assault and rape victims from the UK were analysed and sequentially coded. Sequence analysis allowed to compare all offences combinations regarding their underlying sequence of events. The resulting comparison was transformed and plotted in two-dimensional space by multidimensional scaling analysis for a visual inspection of linkage potential. The transformed proximities of all offences were used as predictors in a receiver operating characteristic analysis to actually test their discriminatory accuracy for crime linkage purpose.

Findings

Sequence analysis shows significant discriminatory accuracy for crime linkage purpose. However, the method does perform less well than previous binary crime linkage studies.

Research limitations/implications

Several limitations due to the nature of the data will be discussed.

Practical implications

The practical limitations are as follows: the study is a potential practical value for crime analysts; it is a complimentary methodology for statistical crime linkage packages; it requires automated coding to be useful; and it is very dependent on crime recoding standards.

Originality/value

The exploratory part of this study has been published in a book chapter in 2015. However, to the best of the authors’ knowledge, the succinct test of crime linkage accuracy is the first of its kind.

Abstract

Purpose

Integrated care models have shown to deliver efficient healthcare, but implementation has proven to be difficult. The Support Consultation is an integrated care model, which enables full integration by bundled payment, insurer involvement, predefined care pathways and strengthening of primary care. The purpose of this paper is to provide an indication of the improvements in healthcare delivery after implementation of this proposed model and to create a base for extension to similar interfaces between primary and secondary care.

Design/methodology/approach

A retrospective study was used to compare the effect on the number of referred patients with non-acute cardiac complaints and the cost effectiveness before and after implementation of the Support Consultation. Patients who previously would have been referred to the cardiologist were now discussed between general practitioner and cardiologist in a primary care setting.

Findings

The first consecutive 100 patients (age 55±16 years, male 48 percent), discussed in the Support Consultation, were analyzed. Implementation of the Support Consultation resulted in a net costs (program costs and referral costs) reduction of 61 percent compared with usual care. All involved parties were positive about the program.

Research limitations/implications

The Support Consultation has the ability to provide more effective healthcare delivery and to reduce net costs. The setting of the current study can be used as example for other specialties in countries with a similar healthcare system.

Originality/value

This study provides the potential cost savings after implementation of an integrated care model, based on real-life data.

Abstract

This study examines problems that may occur when conventional Value‐at‐Risk (VaR) estimators are used to quantify market risks in an agricultural context. For example, standard VaR methods, such as the variance‐covariance method or historical simulation, can fail when the return distribution is fat tailed. This problem is aggravated when long‐term VaR forecasts are desired. Extreme Value Theory (EVT) is proposed to overcome these problems. The application of EVT is illustrated by an example from the German hog market. Multi‐period VaR forecasts derived by EVT are found to deviate considerably from standard forecasts. We conclude that EVT is a useful complement to traditional VaR methods.

Abstract

This study aimed to analyze the most common child’s play of students (approximately seven years old) both during the playtime and the time they are not at school, also considering the teacher’s interpretation of the child’s play practiced in the school, located in a small slum of the metropolitan area of Belo Horizonte. In this way, the analysis considered the issues that involve the recognition of the essentiality of childhood (Dahlberg, Moss, & Pence, 2003; Sarmento, 2007), in the context of the reality and affectivity of children in the place called slum (Coelho, 2007; Perez & Jardim, 2015, Tuan, 1983), as well as in aspects that demonstrate the control of their bodies through the child’s play performed in the school (Brighente & Mesquida, 2011; Foucault, 2009). As a methodological basis, participant observation was chosen because it was believed that from this practice it was possible to extract important experiences and reflections from the research participants, know our actions and, by observing these people, their behaviours and attitudes in routine situations (Lüdke & André, 1986). The results suggested that the slum children’s play, both in school and outside, are different among boys and girls. In the open areas of the slum, the boys explore more spaces than girls, who prefer child’s play in the domestic sphere. At school, educators try to censure some behaviours and attitudes of children, suggesting the pursuit of obedient postures and disciplined bodies. In this context, it is crucial that educators do not convert the school into a place of censorship of the child’s play that resides in the slums and thus transforming the school into a space that reinforces the domestication of bodies from the earliest stages of childhood.

Abstract

Purpose

The purpose of this paper is to investigate the role of creative activity and storytelling in assisting development of students’ reflective ability and critical thinking.

Design/methodology/approach

Eight biomedical science students undertaking year-long work-based placements took part in this action research study. A coding scheme was designed to assess students’ reflections initially and at each stage of the study. Intervention activities involved students using mood boards, images and storytelling to assist development of creative learning spaces with a thematic approach employed to analyse both personal and collective reflections. Post-intervention evaluation considered possible long-term impact on students’ reflective ability.

Findings

Students’ pre-intervention reports showed little reflection focusing mainly on competence demonstration and descriptive situation summaries. During the intervention workshops, all students demonstrated both identification of self as a practitioner and a critically reflective approach. However, this was not maintained long term as initial post-intervention reports tended to revert to a more descriptive style of writing suggesting longer-term support is required.

Research limitations/implications

The importance of further research into the long-term usefulness of creative collaborative learning spaces in work-based programmes is suggested.

Originality/value

This is the first study investigating the approach to supporting critical reflection during work placement in biomedical scientists. It is suggested that the current competence-based training programme provides limited opportunities for developing and embedding critical reflection. Where opportunities are provided, such as creative learning spaces, students’ critical reflection was greatly enhanced. However, it appears essential that this approach is maintained throughout training as critically reflective skills developed during collaborative learning have limited transferability to subsequent reflective report writing.

Abstract

To examine how social media restrict and recreate messages within current interactionist scripts in the Middle East and North Africa (MENA), this study applies a framework of digital reflexivity highlighting stages of information flow. It applies the symbolic interaction concept of emotional events to analyze the self-immolation of Mohamed Bouazizi and the role of social media in disseminating Bouazizi’s act as one catalyst of the MENA citizen uprisings. The role of social media in the “Arab Spring” merits investigation because social media provide opportunities to examine shifting identities, interactions, and actions of citizen activists in the MENA uprisings. This study is important and timely because little symbolic interactionist scholarship exists on MENA identities and social movements, or on crowd interaction and activism outside the West. The nuanced nature of MENA political activism and complex processes of the development of activists’ “mutable” selves (Zurcher, 1977) are fluid and resistant to symbolically defined social roles, interactionist scripts and reflexivity, and public communication practices in a MENA under political and social transition.
