Abstract

Purpose

Research suggests that gang-involved youth are more likely than non-gang youth to experience victimization. However, very little research has addressed the issue of whether the relationship between gang involvement and victimization depends on the context in which victimization takes place. The purpose of this paper is to examine the nature of the relation between gang involvement and violent victimization in both street and school contexts.

Design/methodology/approach

Data were provided by youth (n=421; ages 11-18; 70 percent male; 66 percent non-white) referred by the justice system for intensive home and community-based treatment of problem behavior. At intake, youth reported on their experiences of violent victimization, mental health status, problem behavior, and substance use. Youth and therapist reports were utilized to indicate gang involvement.

Findings

Approximately 62 percent of gang-involved youth in the sample were victimized across both contexts. Linear and censored regression models found that on average, gang-involved youth experienced a greater frequency of victimization than non-gang youth (p < 0.001). Importantly, results also show that gang involvement amplifies the impact of victimization on key behavioral and mental health outcomes. Victimization in both street and school contexts increases the risk of serious problem behavior for gang-involved youth (p < 0.001). Victimization experiences in schools in particular also may increase alcohol use among gang-involved youth (p=0.006).

Originality/value

These findings emanating from a unique sample of youth in treatment demonstrate the value of considering victimization in context for intervention programming.

Abstract

This chapter estimates the negative effect of smoking on earnings in the context of a developing country. Using data from the 2005 Albania Living Standards Measurement Survey, models are estimated by parametric and semi-parametric methods to account for the effect of observable and unobservable characteristics that could affect individual smoking decisions and earnings. Information on the smoking behaviour of parents is used to address the endogeneity of the smoking decision. The results show that, after controlling for observed individual characteristics and parental education and taking into account unobserved heterogeneity in personal characteristics, smoking is found to have a substantial negative impact on earnings. The main results are robust to a range of alternative specifications. On average, smokers’ earnings are 19–23 percent lower than the earnings of similar non-smokers.

Abstract

Bobbie Scull's bibliography of federal government bibliographies was begun in 1971 as an annual informational publication primarily intended for the faculty at Louisiana State University. Later she distributed it to libraries all over the state of Louisiana. In 1973 RSR began to publish these lists on an annual basis. This is the fourth such appearance. In the meantime these bibliographies were cumulated and published in two volumes: Bibliography of U.S. Government Bibliographies 1968–73 and 1974–76. (Pierian Press, 1975, 1979). RSR is proud to continue the annual supplements which are now computer produced at LSU. Although this supplement appears in Volume 8:1 (1980) in the future they will appear in the final issue of the year.

Abstract

Purpose

This study aims to propose an unsupervised learning model to evaluate the credibility of disaster-related Twitter data and present a performance comparison with commonly used supervised machine learning models.

Design/methodology/approach

First historical tweets on two recent hurricane events are collected via Twitter API. Then a credibility scoring system is implemented in which the tweet features are analyzed to give a credibility score and credibility label to the tweet. After that, supervised machine learning classification is implemented using various classification algorithms and their performances are compared.

Findings

The proposed unsupervised learning model could enhance the emergency response by providing a fast way to determine the credibility of disaster-related tweets. Additionally, the comparison of the supervised classification models reveals that the Random Forest classifier performs significantly better than the SVM and Logistic Regression classifiers in classifying the credibility of disaster-related tweets.

Originality/value

In this paper, an unsupervised 10-point scoring model is proposed to evaluate the tweets’ credibility based on the user-based and content-based features. This technique could be used to evaluate the credibility of disaster-related tweets on future hurricanes and would have the potential to enhance emergency response during critical events. The comparative study of different supervised learning methods has revealed effective supervised learning methods for evaluating the credibility of Tweeter data.

Abstract

Purpose

This work critiques the situation of the ecological and cultural heritage in many coastal territories and analyses how current land planning methodologies are responding to it. The study builds a new integrated approach founded on ecocultural values and local knowledge as resources for an effective territorial planning and sustainable development.

Design/methodology/approach

The proposed framework was developed through: (1) analysing coastal planning needs and problems in European coastal areas; (2) identifying ecocultural values, including local knowledge, in such areas; (3) selecting best approaches and tools in spatial planning; (4) applying the selected planning approaches to use ecocultural values as resources for spatial planning and sustainable development; and (5) validating the final methodology.

Findings

A dynamic approach for maritime-land planning was developed projecting coastal waters and river basins as strategic drivers for sustainable development, based on the natural capacity of water to shape and integrate the ecological and cultural territory. A participatory governance planning methodology supports the new articulations of space based on ecocultural value chains and networks as synergistic vectors, focusing on local knowledge as psychosocial capital for a collective mapping of cultural, historical, social, economic and ecological values into ecocultural littoral plans.

Originality/value

The results show the potentials of combining new approaches applying cultural and ecological heritage into an effective strategy of integration between society and territory as a powerful driver for effective sustainable planning and development.

Abstract

The purpose of this chapter is to empirically estimate the propensity for alcohol-related policies to influence rates of child abuse. Child maltreatment is measured by the number of abused children and the number of child fatalities due to abuse. The alcohol regulations of interest include beer, wine, and liquor taxes and prices, drunk driving laws, and measures of alcohol availability. Results indicate that higher excise taxes on alcohol and reductions in availability may be effective in reducing the incidence of child maltreatment.

Abstract

Purpose

The purpose of this paper is to investigate the effects of celebrity’s poses on consumer attitudes towards the endorsement advertisement by drawing from perceptual fluency hypotheses.

Design/methodology/approach

Study 1 used a single-factor, two-condition (distinctive pose and casual pose) between-subject design. Both Study 2a and Study 2b employed a single-factor, two-condition (distinctive pose, casual pose) between-subject design and tested the mediator of pose matchiness. Study 3 employed a 2 (pose condition: distinctive, casual)×2 (cognitive capacity: no load, load) between-subject design to test the moderator. All data were sourced from more than 600 respondents in China.

Findings

Study 1 illustrated that the existence of a distinctive pose can lead to higher consumer attitudes regarding advertising stimuli and the endorsed brands as well as more positive behavioural intentions towards endorsed products. Study 2a and Study 2b replicated such finding and demonstrated that the feeling of pose matchiness mediates the relationship between celebrities’ pose and endorsement outcomes. Study 3 further revealed that the cognitive capacity moderates such a relationship, that is, that the effect of a distinctive pose is stronger (lesser) when audiences’ cognitive capacity is loaded (not loaded).

Originality/value

Research efforts to date examining the nature of celebrity advertisement have been limited to celebrity’s faces and facial expressions. Little investigation in the marketing domain has considered the consequences of celebrities’ poses. This study takes the first step in revealing the positive effect of distinctive celebrity poses in product endorsement.
