The present study uses data from the National Longitudinal Study of Adolescent Health (Ad Health) to evaluate the effects of exposure to violent victimization in childhood on adolescent delinquency and subsequent adult criminality.

Using Longitudinal Latent Class Analysis (LLCA), the present study investigates whether there are distinct and diverse longitudinal delinquency trajectories among those exposed to violence in childhood.

Findings from the current study indicate that there are three distinct trajectories of delinquency and offending from age 14 to 27 for both males and females exposed to violence in childhood. Further, it appears that violent victimization in childhood bridges the gender gap in delinquency between males and females. Thus, childhood violent victimization, and the fact that females are victimized by parents/caregivers and romantic partners at higher rates than males, might be partially responsible in explaining the narrowing of the gender gap between male and female offending in the recent decades. At the same time, childhood violent victimization also seems to impact males and females in somewhat different ways. Practically, all female victims stop offending by their late 20s, whereas a fairly large proportion of males exposed to violent victimization in childhood steadily continue offending.

Although this study was able to identify the diverse impacts of violence exposure on engagement in subsequent delinquency, it did not examine the unique contributions of each type of violence on adolescent outcomes or the chronicity of exposure to each of these types of violent victimization. We were also not able to measure all types of violence experiences in childhood, such as exposure to parents’ or caregivers’ intimate partner violence.

While early prevention would be the most desirable option for both genders for the most optimal outcome, the retrospective intervention and treatment programs should be gender-specific. For males, they should heavily focus on providing alternative ways to cope with anger, impulse control and frustration, as well as teach empathy, cognitive problem solving skills, verbal communication skills, and tangible life and job skills. For females, most successful intervention and treatment programs may focus on helping the girls through a transition from adolescence to adulthood while providing mental health, medical, and family support services.

The paper uses a unique methodological approach to identify distinct and diverse longitudinal delinquency trajectories. The findings demonstrate how more resilient individuals (in terms of externalizing behaviors) can bring down the mean scores of delinquency even though many other individuals can be severely affected by violence exposure in childhood.

The purpose of this paper is to describe risk and protective factors for symptoms of post-traumatic stress disorder (PTSD) experienced over a 1.5-year period among both frontline and “non-traditional” responders to the 2010 and 2011 earthquakes in Christchurch, New Zealand.

A longitudinal survey administered to Christchurch workers with referents from the city of Hamilton at 6, 12 and 18 months after the 2011 earthquake. Potential risk and protective determinants were assessed by questionnaire items at baseline and over time, the outcome being PTSD as assessed by the PTSD Checklist-Civilian version. A longitudinal latent class analysis identified groups with similar trajectories of PTSD.

A total of 226 individuals, 140 (26 per cent) from Christchurch and 86 (16 per cent) from Hamilton, participated at baseline, 180 at 12 and 123 at 18 months, non-traditional responders forming the largest single group. Two latent classes emerged, with PTSD (21 per cent) and without PTSD (79 per cent), with little change over the 18-month period. Class membership was predicted by high scores in the Social Support and Impact of Events scale items, Health-related Quality of Life scores being protective. PTSD scores indicative of distress were found in females, and predicted by burnout risk, behavioural disengagement and venting.

Non-traditional responders should be screened for PTSD. Social support should be considered with the promotion of adaptive coping mechanisms.

The strength was longitudinal follow-up over an 18-month period, with demonstration of how the potential determinants influenced the course of PTSD over time.

On many occasions, organizational science research has been referred to as fragmented and disjointed, resulting in a literature that is, in the opinion of many, difficult to navigate and comprehend. One potential explanation is that scholars have failed to comprehend that organizations are complex and intricate systems. In order to move us past this morass, we recommend that researchers extend beyond traditional rational, mechanistic, and variable-centered approaches to research and integrate a more advantageous pattern-oriented approach within their research program. Pattern-oriented methods approximate real-life phenomena by adopting a holistic, integrative approach to research wherein individual- and organizational-systems are viewed as non-decomposable organized wholes. We argue that the pattern-oriented approach has the potential to overcome a number of breakdowns faced by alternate approaches, while offering a novel and more representative lens from which to view organizational- and HRM-related issues. The proposed incorporation of the pattern-oriented approach is framed within a review and evaluation of current approaches to organizational research and is supplemented with a discussion of methodological and theoretical implications as well as potential applications of the pattern-oriented approach.

Previous literature has recognized the variability of job performance, calling attention to the inter-individual differences in performance change. Building on Murphy’s (1989) theoretical model of performance, the purpose of this paper is to verify the existence of two distinct classes of performance, reflecting stable and increasing trends, and to investigate which personal conditions prompt the inclusion of individuals in one class rather than the other.

Overall job performance was obtained from supervisory ratings for four consecutive years for 410 professionals of a large Italian company going through significant reorganization. Objective data were merged with employees’ organizational tenure and self-efficacy. Growth Mixture Modeling was used.

Two main groups were identified: the first one started at higher levels of performance and showed a stable trajectory over time (stable class); the second group started at lower levels and reported an increasing trajectory (increasing class). Employees’ with stronger efficacy beliefs and lower tenure were more likely to belong to the stable class.

Through a powerful longitudinal database, the nature, the structure and the inter-individual differences in job performance over time are clarified. The study extends Murphy’s (1989) model, showing how transition stages in job performance may occur also as a result of organizational transformation. Moreover, it demonstrates the essential role of self-efficacy in maintaining high performance levels over time.

This study aims to provide the first longitudinal examination of the relationship between affective, calculative, normative commitment and customer loyalty by using longitudinal panel survey data.

Repeated measures for 269 customers of a large financial services provider are employed. Two types of segmentation methods are compared: predefined classes and latent class models and predictive power of different models contrasted.

The results reveal that the impact that different dimensions of commitment have on share development varies across segments. A two-segment latent class model and a managerially relevant predefined two-segment customer model are identified. In addition, the results demonstrate the benefits of using panel survey data in models that are designed to study how loyalty develops over time.

This study illustrates the benefits of including both baseline level information and changes in the dimensions of commitment in models that try to understand how loyalty unfolds over time. It also demonstrates how managers can be misled by assuming that everyone will react to commitment improvement efforts similarly. This study also shows how different segmentation schemes can be employed and reveals that the most sophisticated ones are not necessarily the best.

This research provides the first examination of models for change in customer loyalty by employing survey panel data on the three-component model of customer commitment (affective, calculative, and normative) and considers alternative segmentation methods.

Dynamic market segmentation is a very important topic in many businesses where it is interesting to gain knowledge on the reference market and on its evolution over time. Various papers in the reference literature are devoted to the topic and different statistical models are proposed. The purpose of this paper is to compare two statistical approaches to model categorical longitudinal data to perform dynamic market segmentation.

The latent class Markov model identifies a latent variable whose states represent market segments at an initial point in time, customers can switch to one segment to another between consecutive measurement occasions and a regression structure models the effects of covariates, describing customers’ characteristics, on segments belonging and transition probabilities. The latent class growth approach models individual trajectories, describing a behaviour over time. Customers’ characteristics may be inserted in the model to affect trajectories that may vary across latent groups, in the author’s case, market segments.

The two approaches revealed both suitable for dynamic market segmentation. The advice to marketer analysts is to explore both solutions to dynamically segment the reference market. The best approach will be then judged in terms of fit, substantial results and assumptions on the reference market.

The proposed statistical models are new in the field of financial markets.

This paper focuses on patterns of film consumption within cultural consumption more broadly to assess trends in consumerism such as eclectic consumption, individualised consumption and omnivorous/univorous consumption and whether economic background and status feature in shaping cultural consumption. We focus on film because it is widely consumed, online and offline, and has many genres that vary in terms of perceived artistic and entertainment value. In broad terms, film is differentiated between mainstream commercially driven film such as Hollywood blockbusters, middlebrow “feel good” movies and independent arthouse and foreign language film. Our empirical statistical analysis shows that film consumers watch a wide range of genres. However, films deemed to hold artistic value such as arthouse and foreign language feature as part of broad and wide-ranging pattern of consumption of film that attracts its own dedicated consumers. Though we found that social and economic factors remain predictors of cultural consumption the overall picture is more complex than a simple direct correspondence and perceptions of other cultural forms also play a role. Those likely to consume arthouse and foreign language film consume other film genres and other cultural forms genres and those who “prefer” arthouse and foreign language film have slightly more constrained socio-economic characteristics. Overall, we find that economic and cultural factors such income, education, and wider consumption of culture are significant in patterns of film consumption.

Research on the intergenerational transmission of violence has been limited by reliance on variable-oriented methodology that does not capture heterogeneity that exists within experiences of violent interpersonal conduct. The current study therefore examines the utility of a person-oriented statistical method in understanding patterns of maltreatment and intimate partner violence.

Guided by person-oriented theory, the current study utilizes latent class analysis, a person-oriented method used with cross-sectional data, to examine the heterogeneity within this transmission process in a sample of emerging adults (N = 150). This study also examined whether the classes identified differed on reported emotional reactivity and childhood family environment.

Three classes emerged from the latent class analysis, labeled full transmission, psychological transmission, and no transmission. Those comprising the full transmission subgroup reported the lowest levels of childhood family cohesion, accord, and closeness. The full transmission subgroup also reported significantly more emotional reactivity than the psychological transmission and no transmission subgroups.

To understand fully the etiology of intimate partner violence for maltreated offspring, a multidimensional view of violence is needed. The current study represents a step in this direction by demonstrating the utility of a person-oriented approach in understanding the IGT of violence.

The purpose of this paper is to investigate the developmental trajectory and patterns of physical aggression and relational aggression over time, and also to examine the gender differences of the three-year developmental process as well as the impact of the developmental trajectory on mental health.

Participants: the participants of this study were newly enrolled junior school students. The study spanned three years with continuous tracking performed once every other year. Measures: class play questionnaire. Aggressive behaviors were measured by an adaptive Chinese version of the revised class play assessment. Statistical analysis: to address the questions of the present study, the latent class growth model (LCGM) was used to analyze the three-year longitudinal data by Mplus 6.1.

The initial level of physical aggression in boys was higher than that in girls. There were three types of developmental trajectory for boys, corresponding to a lower initial level-increasing group, a middle initial level-increasing group and a higher initial level-stable group. However, girls demonstrated different patterns, corresponding to a lower initial level-increasing group, a middle initial level-increasing group and a higher initial level-decreasing group. In contrast to the physical aggression, the initial level of relational aggression in boys was lower than that in girls. There were four types of developmental trajectory for boys, corresponding to a lower initial level-increasing group, a middle initial level-increasing group, a middle initial level-declining group and a higher initial level-declining group. Girls illustrated different patterns, corresponding to a lower initial level-stable group, a middle initial level-increasing group and a higher initial level-declining group. Different developmental trajectory of physical and relational aggression would influence the interpersonal relationship.

This paper used a person-centered latent variable approach instead of the variable-centered approach to investigate the developmental trajectory and patterns of physical aggression and relational aggression over three year by employing the LCGM. The initial level of physical aggression in boys was higher than that in girls. In contrast, the initial level of relational aggression in boys was lower than that in girls. There were gender differences in the pattern of physical and relational aggression development trajectory. Different developmental trajectory of physical and relational aggression would influence the interpersonal relationship.
