The Alpha of Indulgent Consensus

This paper presents a simple framework unifying a family of consensus algorithms that can tolerate process crash failures and asynchronous periods of the network, also called indulgent consensus algorithms. Key to the framework is a new abstraction we introduce here, called Alpha, and which precisely captures consensus safety. Implementations of Alpha in shared memory, storage area network, message passing and active disk systems are presented, leading to directly derived consensus algorithms suited to these communication media. The paper also considers the case where the number of processes is unknown and can be arbitrarily larg

The role of parenting styles on behavior problem profiles of adolescents

Parental behavior is one of the most influential factors on the development of adolescent externalizing and internalizing behavior problems. These behavioral problems are closely related and often co-occur. The objectives of this work were: (i) to identify adolescents profiles according to their behavior problems; (ii) to explore individual, family, and social characteristics associated with these profiles; and (iii) to analyze the potential role of parenting styles in belonging to adolescents’ profiles. A total of 449 Spanish adolescents (223 from families declared at-risk and enrolled in Child Welfare Services and 226 from families from the general population) participated in this study. The analyses revealed three profiles of adolescents based on external and internal behavior problems (adjusted, external maladjustment, and internal maladjustment). Parenting styles explained the adolescents’ belonging to different profiles, in which the indulgent style was the most favorable in general terms. The distinctive role of parenting styles on two types of maladjustment profiles was confirmed. The relationship between parenting styles and adolescent adjustment is a key component that should be included in interventions according to adolescents’ behavior problem profiles. Furthermore, the results shed light on the need that family interventions are complemented with individualized interventions with adolescents that accumulate stressful life events.Ministerio de Economía y Competitividad EDU2013-41441-

Corporate Environmental Disclosure Practices in Different National Contexts: The Influence of Cultural Dimensions

The influence of different national contexts, including the effects of cultural environments, on corporate environmental disclosure practices has yet to be properly addressed in the literature. The purpose of this research is, therefore, to analyse how cultural factors affect the environmental disclosure practices of companies in different countries. This research is supported by the diversity of cultures across countries. Given that a cultural framework prompts different organisational actions and strategies, the question to be answered through this research is as follows: How do cultural aspects affect corporate environmental disclosure? Cultural factors are precisely those that can explain similarities and differences between stakeholders’ actions and preferences. The sample used in this research comprises companies in 28 countries and 9 economic sectors for the period 2004 to 2015. Our main findings show that companies operating in countries with individualist, masculine and indulgent cultures are less likely to disclose environmental information. Contrary to our predictions, cultures with a longterm orientation also discourage the reporting of environmental information, while uncertainty avoidance contexts tend to promote more environmental reporting

General and food-specific parenting: measures and interplay

BACKGROUND: Parental influence on child food intake is typically conceptualized at three levels—parenting practices, feeding style, and parenting style. General parenting style is modeled at the most distal level of influence and food parenting practices are conceptualized as the most proximal level of influence. The goal of this article is to provide insights into contents and explanatory value of instruments that have been applied to assess food parenting practices, feeding style, and parenting style. METHODS: Measures of food parenting practices, feeding style, and parenting style were reviewed, compared, and contrasted with regard to contents, explanatory value, and interrelationships. RESULTS: Measures that are used in the field often fail to cover the full scope and complexity of food parenting. Healthy parenting dimensions have generally been found to be positively associated with child food intake (i.e., healthier dietary intake and less intake of energy-dense food products and sugar-sweetened beverages), but effect sizes are low. Evidence for the operation of higher-order moderation has been found, in which the impact of proximal parental influences is moderated by more distal levels of parenting. CONCLUSIONS: Operationalizing parenting at different levels, while applying a contextual higher-order moderation approach, is advocated to have surplus value in understanding the complex process of parent–child interactions in the area of food intake. A research paradigm is presented that may guide future work regarding the conceptualization and modeling of parental influences on child dietary behavior

Relationships between Parental Socialization Styles, Empathy and Connectedness with Nature: Their Implications in Environmentalism

Parents exert a strong influence on several adjustment outcomes. However, little is known about their influence on adolescents’ connectedness with the environment. This study examined the relationships between parenting styles, empathy and connectedness with the environment. The two-dimensional socialization model was used with four resulting styles: Indulgent, authoritative, neglectful and authoritarian. The sample comprised 797 adolescents (52.7% girls) from six public secondary schools who were aged between 12 and 16 years (M = 13.94, SD = 1.28). The results showed significant relationships between parental socialization styles, empathy and connectedness with nature. It was also observed that adolescents from indulgent and authoritative families showed higher levels of empathy and connectedness with the environment than adolescents raised by authoritarian and neglectful parents, with males from such families consistently presenting the lowest levels of empathy and connectedness, which was not the case among women. Additionally, women, regardless of the parental style in which they had been educated, showed greater cognitive and emotional empathy with the natural environment, while adolescents raised in indulgent and authoritative families displayed higher levels of empathy and connectedness than those with authoritarian and neglectful parents. These results suggest that indulgent and authoritative styles are stronger enablers of empathy and connectedness with nature

Perceived parenting styles and adjustment during emerging adulthood: a cross-national perspective

The aim of the present study is to determine whether the influence of parenting style on children’s wellbeing is sustained during emerging adulthood. This is a stage in which young people, despite feeling themselves to be adults, often remain in the family home and continue to be financially dependent on their parents. Moreover, since parents’ beliefs, attitudes and behaviors are constructed and interpreted within their cultural milieu, the study also aims to explore the situation in Spain (SP) and Portugal (PT). Those two Southern Europe countries are representative of what is known as the “family welfare regime”, in which the family acts as the main provider of care and security not only during childhood, but also during emerging adulthood. Thus, the present study examines, from a cross-cultural perspective, the relationship between perceived parenting styles and psychological adjustment among a sample of 1047 emerging adults from Spain and Portugal. The results reveal that the most beneficial styles during this stage are the authoritative and permissive ones, with the authoritarian style being more closely related to psychological distress. The study highlights intercultural similarities and the positive role played by more symmetrical relationships in the adjustment of emerging adults in both countries.Ministerio de Economía y Competitividad EDU2013-45687-RMinisterio de Economía y Competitividad RTI2018-097405-B-I0

Substance Use in Early and Middle Adolescence. The Role of Academic Efficacy and Parenting

This study examines (i) the relationships between substance use and parenting style and between substance use and perceived academic self-efficacy in early and middle adolescence, (ii) the importance of these factors in predicting adolescent substance use, and (iii) the role of academic self-efficacy in the relationship between parenting styles and adolescent substance use. The sample comprised 762 adolescents (53% boys) aged 12 to 16 years (M = 13.66, SD = 1.34). The sample was selected using probabilistic cluster sampling according to type of school (secondary, public vs. semiprivate) and school location in different areas of the city of Valencia (Spain). This approach accounted for different social strata of families. The results show that substance use and parents' neglect are greater in middle adolescence than in early adolescence. Support and family communication and perceived academic self-efficacy are lower. Substance use is positively related to parents' neglect, psychological control, and rejection. The relationships between neglect and psychological control and substance use are moderated by academic self-efficacy, and the relationship between psychological control and substance use is mediated by academic self-efficacy

Cue Reactivity to Images of Alcohol: Creation of a Standardized Picture Set

To study alcohol approach inclinations in a laboratory setting, researchers commonly use cue reactivity paradigms involving presentation of alcohol cues and measurement of responses. However, available picture sets present potential limitations due to their multidimensional nature. A critical task was to develop a set of standardized images without brand labels, actors, or settings, in order to gain a clearer assessment of college students’ reactions to alcohol, and alcohol alone, while minimizing contextual influences. In Study 1, a set of images with satisfactory reliability was created. To replicate and expand upon these findings, Study 2 included a sample of 163 participants (82 women, M age = 18.8, 59.3% Caucasian). Following completion of a questionnaire packet of different measures of approach toward alcohol, participants rated 30 affective images from the International Affective Picture System (IAPS), and 30 images of alcohol (beer, wine, liquor). Results demonstrated that our standardized picture set has acceptable psychometric properties associated with an approach valence. Specifically, valence ratings showed (a) acceptable internal consistency and (b) convergent validity with other measures of behavioral approach toward alcohol (viz., reported frequency of alcohol consumption, average number of drinks consumed per drinking day, number of binge drinking days and total drinks consumed per week). These findings suggest that our alcohol images were associated with producing an approach response and support their continued use in college populations

The effectiveness of a web-based Dutch parenting program to prevent overweight in children 9–13 years of age:Results of a two-armed cluster randomized controlled trial

INTRODUCTION: Although parental support is an important component in programs designed to prevent overweight in children, current programs pay remarkably little attention to the role of parenting. We therefore developed a web-based parenting program entitled “Making a healthy deal with your child”. This e-learning program can be incorporated into existing overweight prevention programs. The aim of this study was to determine the effectiveness of this e-learning program. MATERIALS AND METHODS: The effectiveness was examined in a two-armed cluster randomized controlled trial. The participants were 475 parent-child dyads of children 9–13 years of age in the Netherlands who participated in an existing schoolclass-based overweight prevention program. At the school grade level, parents were randomly assigned to either the intervention or the control condition. Measurements were taken from both parents and children at baseline, and 5 and 12 months after baseline. Primary outcomes included the child’s dietary and sedentary behavior, and level of physical activity. Secondary outcomes included general parenting style, specific parenting practices, and parental self-efficacy. Linear mixed effects models and generalized linear mixed effects models were conducted in R. RESULTS: Intention-to-treat analyses and completers only revealed no significant effects between the intervention and control condition on energy balance-related behaviors of the child and parenting skills after correction for multiple testing. The parents’ mean satisfaction with the e-learning program (on a 10-point scale) was 7.0±1.1. CONCLUSIONS: Although parents were generally satisfied with the parenting program, following this program had no significant beneficial effects regarding the children’s energy balance-related behaviors or the parenting skills compared to the control condition. This program may be more beneficial if used by high-risk groups (e.g. parents of children with unhealthy energy balance-related behaviors and/or with overweight) compared to the general population, warranting further study
