Comparing serial homicides to single homicides: A study of prevalence,offender, and offence characteristics in Sweden

Multiple and serial homicides constitute around 1.6% of all homicides but have unusually tragic outcomes. The aims of this study were to report the prevalence serial‐homicide offences and the characteristics of serial‐homicide offenders in a non‐North American context. The study included all convicted serial‐homicide offenders in Sweden from 1973 to 2012 (n = 25), as well as a population‐based control sample of single‐homicide offenders collected during 2007 and 2009 (n = 201). Similar to U.S. findings, approximately 1.6% of homicides could be attributed to serial‐homicide offenders. Serial offenders were more often diagnosed with personality disorders and autism‐spectrum disorders compared with single offenders; and serial offences more often involved victims who were female and unacquainted with the offender, as well as planning, sexual motives, and asphyxia as method of violence. One third of serial offences involved actions aimed at disguising the manner of death; such actions were considerably less common in single‐homicide offences. Few offenders displayed the traditional profile of a serial‐homicide offender; however, one third displayed sexual motives, a rate roughly 10 times higher than that in the single‐homicide group. The study concludes that serial‐homicide offenders should be subjected to forensic‐psychiatric examinations and that research involving cross‐contextual differences and similarities in serial‐homicide offenders is needed.     

Classification of Planning and Violent Behaviours in Serial Homicide: A Cross‐National Comparison Between South Africa and the US

Recent literature suggests that different ‘styles’ of homicide will most appropriately be reflected in the different types of behaviours committed by offenders during the crime. In the last few years, there has been a move to standardise classification systems of single homicides and establish their cross‐national generalisability. Literature on serial homicide to date has mostly centred on homicides occurring in the US. However, national differences due to factors such as culture, national identity, political, and socio‐economic circumstances may decrease the applicability of these models or certain aspects thereof in other countries and thus must be evaluated. The present study tested the applicability in the South African context of a recently developed US‐based serial homicide crime scene classification framework. Specifically, this study compared the thematic differentiation in planning and violent behaviours that the offenders engage in and how this differentiation compares with that in the US. The sample consisted of 25 homicides that were in total responsible for the murder of 267 victims. Results indicated that overall, the framework is useful and applicable in the South African sample, but important environmental and contextual constraints must be taken into account.

Statistical modelling in the investigation of stranger rape

A sample of stranger rape offences (n = 271) registered in the Dutch Violence Crime Linkage Analysis System database in the Netherlands between 1997 and 2007 was studied with the objective of developing statistical models, which give an indication of the probability of basic offender characteristics. Observable crime characteristics concerning the modus operandi, interaction between the offender and the victim, violence, precautionary measures, and sexual behaviours were selected in the dataset. Offender characteristics were selected based on their usefulness for the police organisation in narrowing the scope of a criminal investigation. Spatial behaviour, criminal history, and living situation of the offender were selected. From the predictive models, four out of five achieved a correct rate of over 70%, and all models predicted better than the best guess method. The proposed models for distance and prior convictions for violence seem particularly promising. Both these models show an improvement of correctly predicted offender characteristics of more than 20 percentile points compared with that which could have been estimated based on the average in the total sample. The predictive value of the models needs to be tested further with ‘new offences’, which were not used to construct the model. In general, the current study supports the finding that crime characteristics can be used to get an indication of the probability of certain offender characteristics. Nevertheless, for an understanding of the relationship between the crime characteristics and offender characteristics, a further development of a theoretical framework is urgently necessary.

Improvement of Thematic Classification in Offender Profiling: Classifying Serbian Homicides Using Multiple Correspondence,Cluster, and Discriminant Function Analyses

This paper investigates thematic classification of homicides for the purpose of behavioural investigative analysis (e.g. offender profiling). Previous research has predominantly used smallest space analysis (SSA) to conceptualise and classify offences into thematic groups based on crime scene behaviour data. This paper introduces a combined approach utilising multiple correspondence analysis (MCA), cluster analysis (CA), and discriminant function analysis (DFA) to define and differentiate crime scenes into expressive or instrumental and impersonal or personal crimes. MCA is used to derive the latent structural dimensions in the crime data and produce quantitative scores for each offence along these dimensions. Two‐step CA was then utilised to classify offences. Offence dimensional scores were then used to predict cluster membership under DFA, producing cluster centroids corresponding to MCA dimensions. Centroids were plotted on the MCA correspondence map to simultaneously conceptualise crime classification and the latent structure of the Serbian crime data. Classification of offences based on MCA dimensional scores were 91.5% accurate. This MCA–CA–DFA approach may reduce some of the more subjective aspects of SSA methodology used in classification, whilst producing a product more amenable to objective and cumulative review. Implications for offender profiling research utilising SSA and this approach are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Perceptions of stranger and acquaintance rape: the role of benevolent and hostile sexism in victim blame and rape proclivity

In Studies 1 and 2, after reading an acquaintance-rape but not a stranger-rape scenario, higher benevolent sexist but not hostile sexist participants blamed the victim significantly more. In Study 2, higher hostile sexist but not benevolent sexist male participants showed significantly greater proclivity to commit acquaintance (but not stranger) rape. Studies 3 and 4 supported the hypothesis that the effects of benevolent sexism and hostile sexism are mediated by different perceptions of the victim, as behaving inappropriately and as really wanting sex with the rapist. These findings show that benevolent sexism and hostile sexism underpin different assumptions about women that generate sexist reactions toward rape victims.     

Expressive language and prosocial behaviour in early childhood: Longitudinal associations in the UK Millennium Cohort Study

Background: Early childhood is a crucial period for language development and building social skills. While distinct, these two processes may impact upon each other.

Aims: The current study aimed to identify the directional associations between expressive language ability and prosocial behaviour between three and five years of age.

Methods: Participants included 14, 004 children and their families enrolled in the UK Millennium Cohort Study. Children’s expressive language and prosocial behaviour were assessed at three and five years of age utilizing standardized assessments and parent reports. Cross-lagged models were used for data analysis.

Results: Better expressive language at three years was associated with increased prosocial behaviour by five years. No support for the inverse direction of association was found.

Conclusions: Children’s early ability to effectively express themselves with others may help in building better social relationships by entry into formal schooling. Programming efforts that are tailored towards enhancing positive behavioural growth and social skills in the toddler years are likely to be effective when expressive language is also a targeted component of the toddler’s skill development.     

Investigating the mediating effects of emotional intelligence and coping on problem behaviours in adolescents

This study explored the mediating effect of emotional intelligence (EI) and coping strategies on problem behaviours in Australian adolescents. One hundred and forty‐five adolescents (60 boys and 85 girls with a mean age of 12.02 years) completed self‐report instruments of EI, stress coping strategies, and problem behaviours. The relationships between Emotional Management and Control and engagement in internalising and externalising behaviours were found to be mediated by the use of non‐productive coping strategies. Mediation models of the relationship between problem behaviours and the Understanding Emotions and Emotional Recognition and Expression dimensions were found to be only partially mediated by the engagement in problem‐focused and non‐productive coping strategies. The results are discussed in regards to how coping strategies utilised in adolescence may produce more or less adaptive patterns of coping during adulthood. The development of emotional abilities may be required to improve coping outcomes for adolescents, which in turn may produce better psychological outcomes for adolescents in the long term.     

Investigating a process model for leader affective presence,interpersonal emotion regulation,and interpersonal behaviour in teams

Leader affective presence is the tendency of leaders to elicit feelings that are consistent among other individuals, and has been supported as a relevant personality trait for understanding teamwork. Drawing on a model that integrates personality and emotion regulation, this study aimed to expand research on affective presence by proposing team members’ perceptions of leader interpersonal emotion regulation as a process that explains how leader affective presence is related to team member behaviour. In the model, teamness—the perception that interdependence and reflexivity are required in the team—is presented as a boundary condition to the effects of affective presence via emotion regulation. Results of a study conducted with 99 teams showed that team member ratings of leader positive affective presence were linked to their perceptions that leaders had used affect-improving emotion regulation which in turn was associated with greater team citizenship behaviour. Contrariwise, team member ratings of leader negative affective presence were associated with perceived use of affect-worsening emotion regulation by leaders which in turn was associated with lower levels of team citizenship, but only when teams were low in teamness. These findings contribute to understanding how leaders’ individual differences are related to teamwork through affective processes.     

Investigating the nature and time-course of the modality shift effect between vision and touch

It is well known that stimuli grab attention to their location, but do they also grab attention to their sensory modality? The modality shift effect (MSE), the observation that responding to a stimulus leads to reaction time benefits for subsequent stimuli in the same modality, suggests that this may be the case. If noninformative cue stimuli, which do not require a response, also lead to benefits for their modality, this would suggest that the effect is automatic. We investigated the time-course of the visuotactile MSE and the difference between the effects of cues and targets. In Experiment 1, when visual and tactile tasks and stimulus locations were matched, uninformative cues did not lead to reaction time benefits for targets in the same modality. However, the modality of the previous target led to a significant MSE. Only stimuli that require a response, therefore, appear to lead to reaction time benefits for their modality. In Experiment 2, increasing attention to the cue stimuli attenuated the effect of the previous target, but the cues still did not lead to a MSE. In Experiment 3, a MSE was demonstrated between successive targets, and this effect decreased with increasing intertrial intervals. Overall, these studies demonstrate how cue- and target-induced effects interact and suggest that modalities do not automatically capture attention as locations do; rather, the MSE is more similar to other task repetition effects.     

The influence of the perception of a familial climate on job performance: mediation of loyalty to supervisors and moderation of filial behaviour

With a collectivist cultural perspective, we examined the positive effects of employees' perceptions of a familial climate on loyalty to supervisors, the mediation of loyalty between perception of a familial climate and job performance, and the moderation of employees' filial behaviour on the relationship between perception of a familial climate and loyalty. The participants consisted of 247 supervisor-and-subordinate dyads in Taiwan. The results supported our hypotheses. Through the mechanisms of family behaviour transference, social identification and supervisor-subordinate exchange, perception of an organizational familial climate enhanced loyalty to supervisors. Furthermore, loyalty to supervisors mediated the relationship between perception of a familial climate and job performance. Filial behaviour moderated the relationship between perception of a familial climate and loyalty; thus, the relationship of perception of a familial climate and loyalty was stronger for employees with low levels of filial behaviour and weaker for employees with high levels of filial behaviour. These findings are discussed in terms of their theoretical and practical implications for future research and management practices.     

Differentiation of international terrorism: attack as threat,means, and violence

This study examined whether international terrorism could be differentiated into different behavioural themes related to the way of using force. The sample consisted of 217 international terrorist organisations that had perpetrated five or more terrorist incidents. A non‐metric multidimensional scaling analysis revealed that all of the terrorist incidents could be assigned to one of three themes reflecting different styles of the use of force: ‘attack as threat’, ‘attack as means’, and ‘attack as violence’. In the current sample, 189 of the terrorist organisations repeated one theme in more than 50% of their series of incidents, suggesting their preference for one of the three themes.

Testing the Situationism Scale in Europe: Scale validation,self‐regulation and regional differences

The term situationism refers to an individual's belief about the importance of a behaviour's context. This study tested whether the degree of situationism expressed by individuals in various regions of Europe was consistent with self‐regulation and cross‐cultural theories. The English version of a Situationism Scale (measuring beliefs about the relation between the environment and one's own behaviour) was translated into five additional languages: Dutch, German, Hungarian, Italian and Slovenian. Young adults (N = 1106, M_Age = 22.9 years, 79% female) across Europe responded to one of the six language versions of the scale as part of a larger survey. Results indicated that: new language versions were psychometrically valid; there was a positive relation between situationism and the use of situation‐control strategies; and situationism was higher for individuals from regions that are Eastern European and relatively more interdependent, compared with individuals from regions that are Western European and relatively less interdependent. As the first evaluation of the Situationism Scale outside America, this study supports the Scale's validity and suggests not only may some effects of situationism be universal, but between‐ and within‐culture differences in situationism exist. Overall, when making judgments and decisions about the self, cultural background and individual differences in situationism may come into play.     

Juvenile prostitution and community rehabilitation: an exploratory analysis of beliefs and values

A community, juvenile prostitution rehabilitation programme in Bogotá, Colombia, South America is described; and beliefs and values of the residents were explored. Multiple sorting procedures and multi‐dimensional scaling analysis elicited qualitative, structured, self‐report data, and investigated cognitive constructs. Participants discriminated between belief‐statements along two global dimensions: street‐life and prostitution; and rehabilitation. These were comprised of qualitatively different elements. Clinical implications for interventions with this group and the rehabilitation programme are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Causal attributions of obese men and women in genetic testing: Implications of genetic/biological attributions1

The present study sought to investigate genetic/biological attributions of obesity, their associations with a predisposition to obesity and their crossectional and longitudinal implications for weight regulation in obese individuals presenting for genetic testing and counselling. A total of 421 obese men and women underwent psychological and anthropometric assessment and a mutation screen of the melanocortin-4 receptor gene. At study entry, women revealed more genetic/biological attributions than men on the Revised Illness Perception Questionnaire adapted to obesity (86.2% versus 59.7%). Genetic/biological attributions of obesity were associated in both sexes with a family history of obesity, assessed through Stunkard's Figure Rating Scale. In both sexes, genetic/biological attributions were unrelated to weight regulation beliefs and behaviour (i.e. self-efficacy, controllability beliefs, restrained eating and physical activity), assessed through standardised questionnaires or interview at baseline and at six-month follow-up. In addition, causal attributions and weight regulation beliefs and behaviour were not predictive of body mass index at six-month follow-up. Overall, the results indicate that causal attributions of obesity to genetic/biological factors in obese individuals presenting for genetic screening and counselling are crossectionally and longitudinally unrelated to weight regulation and longer-term weight outcome. Those who attribute their obesity to genetic/biological factors likely have a familial obesity risk.     

Investigating the Relationships Between Mobility Behaviours and Indicators of Subjective Well-Being Using Smartphone-Based Experience Sampling and GPS Tracking

People interact with their physical environments every day by visiting different places and moving between them. Such mobility behaviours likely influence and are influenced by people's subjective well-being. However, past research examining the links between mobility behaviours and well-being has been inconclusive. Here, we provide a comprehensive investigation of these relationships by examining individual differences in two types of mobility behaviours (movement patterns and places visited) and their relationship to six indicators of subjective well-being (depression, loneliness, anxiety, stress, affect, and energy) at two different temporal levels of analysis (two-week tendencies and daily level). Using data from a large smartphone-based longitudinal study (N = 1765), we show that (i) movement patterns assessed via GPS data (distance travelled, entropy, and irregularity) and (ii) places visited assessed via experience sampling reports (home, work, and social places) are associated with subjective well-being at the between and within person levels. Our findings suggest that distance travelled is related to anxiety, affect, and stress, irregularity is related to depression and loneliness, and spending time in social places is negatively associated with loneliness. We discuss the implications of our work and highlight directions for future research on the generalizability to other populations as well as the characteristics of places. © 2020 European Association of Personality Psychology     

Exclusive and inclusive protest in Europe: Investigating values,support for democracy,and life conditions

Dissatisfaction with the economic situation and perceived governmental inefficacy in regard to the financial crisis has spawned a widespread feeling of political distrust across Europe. This distrust has been translated into protests against institutional authority that aims at either expanding democratic procedures or supporting xenophobic and populist measures. This research uses European Social Survey data to compare exclusive and inclusive protesters with regard to a number of personal and social values, attitudes toward democratic principles, and different life conditions and socio‐economic resources. It also considers contextual factors to investigate how different protesters' profiles are interwoven with socio‐economic conditions. The results of a multilevel latent profile analysis show that exclusive and inclusive protesters, despite sharing similar levels of political distrust, differ with regard to key values and political attitudes, and these differences are related to individual and collective living conditions. We argue that unfavourable living conditions play a non‐negligible role in increasing the probability of easy (i.e., populist) scapegoat political attitudes. Further support for this hypothesis is provided by the cross‐country analysis, which shows that higher levels of exclusive protest are present in countries that were characterized by worse living conditions before the economic crisis.     

Play among the stars: Astrobiology and intra‐action in Pryor's Living with Tiny Aliens

Pryor's new book, Living with Tiny Aliens: The Image of God for the Anthropocene, uses astrobiology to explore integrated and nonanthropocentric views of the IMAGO DEI with a particular emphasis on planetarity and intra‐action. This review and reflection articulates and amplifies Pryor's view of humans in the context of Earth, arguing for ideas of both Anthropocene and IMAGO DEI that are anthropic (aware of the human context) but not anthropocentric (over‐valuing humanity). It raises a caution about how historical and normative claims of progress and transcendence than can color both in unhelpful ways.
