Public Policy and the Effects of Media Violence on Children

Policymakers and the public have been concerned about the effects of media violence on children for decades. Scientific psychological research can be an important source of information for policy, as the goal of science is to separate facts from opinions. This article reviews children's exposure to media violence, describes theories that explain the effects media violence could have, summarizes the research on the effects of media violence exposure, and describes several moderators that can enhance or mitigate those effects. These scientific findings provide useful information for public policy, yet there are many barriers to their use, including misunderstandings of how causality is determined in scientific and public health circles and how large the effects are. Finally, the implications for public policy are discussed, including what has and has not worked in the United States, what other countries and the international community are doing, and where opportunities for new approaches for effective policies may exist.     

Normative, Gain and Hedonic Goal Frames Guiding Environmental Behavior

This article discusses new developments about goal-dependent framing and multiple goal frames (sometimes also called "multiple motives"), which are highly relevant for understanding environmental behavior. We introduce goal-framing theory, which postulates that goals "frame" the way people process information and act upon it. Three goal frames are distinguished: a hedonic, gain, and normative goal frame. In general, multiple goals are active at any given time, which may (or may not) be compatible; that is, the strength of the focal goal may be influenced by other goals that are in the background. Based on an extensive review of studies in environmental psychology, we suggest those conditions under which each goal frame may be dominant in influencing environmental behavior. In the environmental context, normative goal frames imply acting pro-environmentally, while gain and hedonic goal frames often result in not acting in an environmentally sound manner. Next, we argue that pro-environmental behavior may be promoted by strengthening normative goals or by making gain and hedonic goals less incompatible with normative goals. Finally, based on goal-framing theory, we suggest questions to be addressed in future research.     

Current reproductive technologies: increased access and choice?

This article discusses key issues related to current reproductive technologies including contextual and personal barriers to use, complexity of decision making, limited access to technologies for poor women and women of color, and the politics and social controversy surrounding this area. New reproductive technologies have to be put to the same test as any other product--can and will women use them correctly? We need to not only know about the technology itself; we also need to know about the individuals who intend to use the technology and about contextual factors that influence use. Accordingly, the articles in this issue focus on the multiple determinants that influence acceptability of reproductive technologies and the policy, political, and legal implications associated with their use.     

Developmental Idealism and Cultural Models of the Family in Malawi

This paper examines the extent to which developmental idealism has been disseminated in Malawi. Developmental idealism is a set of beliefs and values about development and the relationships between development and family structures and behavior. Developmental idealism states that attributes of societies and families defined as modern are better than attributes defined as traditional, that modern societies help produce modern families, that modern families facilitate the achievement of modern societies, and that the future will bring family change in the direction of modernity. Previous research has demonstrated that knowledge of developmental idealism is widespread in many places around the world, but provides little systematic data about it in sub-Saharan Africa or how knowledge of it is associated with certain demographic characteristics in that region. In this paper, we address this issue by examining whether ordinary people in two settings in Malawi, a sub-Saharan African country, have received and understood messages that are intended to associate development with certain types of family forms and family behaviors. We then examine associations between demographic characteristics and developmental idealism to investigate possible mechanisms linking global discourse about development to the grassroots. We analyze data collected in face-to-face surveys from two samples of Malawian men in 2009 and 2010, one rural, the other in a low-to-medium income neighborhood of a city. Our analysis of these survey data shows considerable evidence that many developmental idealism beliefs have been spread in that country and that education has positive effects on beliefs in the association between development and family attributes. We also find higher levels of developmental idealism awareness in the urban sample than we do in the rural sample, but once dissimilarities in education and wealth between the two samples are controlled, awareness levels no longer differed between urban and rural respondents. We explore how these beliefs intersect with longstanding local values and beliefs in Malawi.     

Balancing Justice and Welfare Needs in Family Group Conferences for Children with Harmful Sexual Behavior: The HSB-FGC Framework

In England and Wales, family group conferences (FGCs) are most often found either in the field of youth justice or in the field of child protection, and consequently often have priorities in line with either one of the two systems. On the one hand, FGCs are a restorative justice tool to address offending behavior and hold young perpetrators to account, while giving victims the possibility of contributing to the justice process. On the other hand, FGCs address safeguarding concerns and are used to plan for child safety and protection. In cases where a young person has sexually harmed another young person, that is, has perpetrated harmful sexual behavior (HSB), all young people involved will have both justice and welfare needs. FGCs are emerging as promising mechanisms in such cases, not only because of their ability to deal with both sets of needs for both young people but also because of their potential to address more holistic needs. However, HSB cases are often complex and sensitive, and are not without risk. Drawing on their experiences in research and practice, the authors explore how the holistic needs of both the harmed and harming individual can be balanced within a risk managed HSB-FGC framework.     

Generalized autoregressive and moving average models: multicollinearity,interpretation and a new modified model

In this paper, we call attention of two observed features in practical applications of the Generalized Autoregressive Moving Average (GARMA) model due to the structure of its linear predictor. One is the multicollinearity which may lead to a non-convergence of the maximum likelihood, using iteratively reweighted least squares, and the inflation of the estimator's variance. The second is that the inclusion of the same lagged observations into the autoregressive and moving average components confounds the interpretation of the parameters. A modified model, GAR-M, is presented to reduce the multicollinearity and to improve the interpretation of the parameters. The expectation and variance under stationarity conditions are presented for the identity and logarithm link function. In a general sense, simulation studies show that the maximum likelihood estimators based on the GARMA and GAR-M models are equivalent but the GAR-M estimators presented a little lower standard errors and some restrictions in the parametric space are imposed to guarantee the stationarity of the process. Also, a real data analysis illustrates the GAR-M fit for daily hospitalization rates of elderly people due to respiratory diseases from October 2012 to April 2015 in São Paulo city, Brazil.     

Point-of-expansion,structure, and selection in multivariable polynomial regression

This article discusses three issues important in multiple linear regression analysis when a polynomial response function is used. These are (1) the role of the point of expansion, about which the response function is formulated, (2) the effect of polynomial structure among the predictor variables, and (3) the appropriate use of methods for selecting predictors. Two examples are included for illustration.     

Evaluation of quadratic forms and traces for iterative estimation in first-order moving average models

This paper deals with the evaluation of certain quadratic forms and traces associated with the irst-order moving average model. The problem arose while considering the maximum likelihood estimation under normality of the parameters of this model. The quadratic forms are y¹R-^jy, where y is a vector of observations generated by the models and R is the correlation matrix of the model; the traces are trR-^j j cam be any natural number, but emphasis is placed on small Yalues, j = 1,2,3. Procedures in the time and frequency domains are studied, and the amount of computations needed in each case are considered and compared, from which a preferred approach emerges. The computations are compared with several alternative procedures suggested in the literature.     

Infants born full term and preterm increase the height of anti-gravity leg movements during a kick-activated mobile task using a scaffolded task environment

Prior research supports that infants born very preterm (PT), compared with full term (FT), have early differences in rate of learning and motor control that may hinder their ability to learn challenging motor tasks. Four-month-old infants born FT (n = 18) and PT (n = 18) participated in an infant kick-activated mobile task that was scaffolded to motivate progressively higher kicks. We found the FT group learned the association between their leg movements and mobile activation on the second day, but the PT group learned the association on the third day. Both groups of infants increased the height of their kicks on the day they learned the task, compared with their spontaneous kicking height. These findings suggest that infants born PT have the ability to learn challenging motor tasks, such as kicking high, when participating in a task environment that uses scaffolding.     

Experienced crawlers avoid real and water drop-offs,even when they are walking

Crawling experience was recently linked to crawling and walking infants’ avoidance of falling on real and water cliffs, whereas walking experience had no effect on walkers’ avoidance behavior (Burnay et al., 2021). In the current study, the behavior of 25 infants was analyzed on the Real Cliff/Water Cliff apparatus using a longitudinal study design. Infants were tested as experienced crawlers (M_crawling = 2.93 months, SD = 1.07), novice walkers (M_walking = 0.68 months, SD = 0.29), and experienced walkers (M_walking = 4.90 months, SD = 0.92). Infants avoided falling on both cliffs when tested as experienced crawlers and their behavior was not different when tested as novice or experienced walkers. These findings confirmed the effect of crawling experience on crawling and walking infants’ avoidance of falls from heights and into water and the transfer of perceptual learning from crawling to walking postures.
