Factors related to the comorbidity between oppositional defiant disorder and anxiety disorders in preschool children

Background and objectives: The aim of the study is to identify factors related to comorbid oppositional defiant disorder (ODD) and anxiety disorders (ADs). Design: A sample of 622 children was assessed longitudinally at 3 and 5 years of age. Methods: At baseline, there were 310 boys (49.8%), most participants were of Caucasian–white ethnicity (89.1%) and attended to public school (64.0%), and families’ socioeconomic status was 64.3% medium-high, 14.1% medium and 20.5% medium-low. Children diagnosed with ODD and/or AD were selected: n?=?103 at 3 years of age (44 ODD, 42 AD and 17 ODD?+?AD) and n?=?106 at 5 years of age (31 ODD, 60 AD and 15 ODD?+?AD). Results: High levels of the child’s negative affectivity and the mother’s aggressive behavior (versus AD), and high scores in the father’s psychopathology measurements (versus ODD) were related to the presence of comorbid ODD?+?AD at 3 years of age. High scores in approach-positive anticipation, fears (only in boys, in girls the reverse effect occurred) compared to ODD and AD independently and aggressive behavior (versus AD), and low scores for smiling and laughter (versus ODD only and AD only) were predictive of comorbidity at the 5 years of age. Conclusions: Temperament traits may be a common factor in explaining longitudinal ODD?+?AD comorbidity.     

The natural course of anxiety symptoms in early adolescence: factors related to persistence

Background and objectives: Anxiety disorders are the most common mental health problems during childhood and adolescence. This study examined the course of anxiety symptoms in early adolescents from the general population over three phases.

Design: Prospective cohort study.

Methods: Two hundred and forty-two participants (mean-age of 13.52) from a baseline sample of 1514 (mean-age of 10.23) were followed up three times. Of the 1514 children, those with emotional risk and controls without risk constituted the second-phase sample (n?=?562; mean-age of 11.25). The Screen for Child Anxiety Related Emotional Disorders-SCARED was administered in all three phases.

Results: Fifty-six percent and 32% of respondents showed total scores above the SCARED cutoff point at one and three years follow-up, respectively. Eight percent showed fluctuating symptoms. Fifty-five percent of respondents showed high scores for any subtype of anxiety over three years. Social phobia and generalized anxiety symptoms were the most prevalent and persistent. Participants with persistent separation anxiety showed the highest co-occurrence with symptoms of other psychopathological disorders. Participants with persistent anxiety showed lower academic performance. Being male was a protective factor against persistence.

Conclusions: The data support anxiety maintenance during early adolescence. Early adolescence is a critical period which may involve other serious academic, social, and family problems.     

How do Curiosity,Meaning in Life,and Search for Meaning Predict College Students’ Daily Emotional Exhaustion and Engagement?

College students face numerous academic demands on a daily basis. The resources of the University and of the students to cope with these demands are essential to explain students’ levels of well-being. The purpose of this investigation is to explore the role of day-level curiosity and meaning in life in the explanation of students’ levels of engagement and emotional exhaustion at night. Two-hundred and nine college students participated in a daily study of five consecutive academic days, completing measures of curiosity and meaning in life in the afternoon and measures of engagement and emotional exhaustion at night. Data were analyzed using MLwiN software from a hierarchical linear modeling and daily approach. Curiosity in the afternoon showed a positive relationship with levels of engagement at night, and a negative relationship with levels of emotional exhaustion at night. Moreover, the interaction of curiosity and search for meaning and emotional exhaustion was positive. Although curiosity drives to exploring opportunities and challenges, decreases exhaustion and promotes daily engagement, when curiosity interacts with other emotional loads (such as search for meaning), it can become an emotional overload favoring exhaustion. From this perspective, it is necessary to continue investigating the mechanisms that predict students’ well-being and to create academic environments that stimulate curiosity and support students in their search for meaning in life.     

Missional Formation for Transforming Discipleship

Mission – in the larger sense, beyond the mission of the institutional church – in the 21st century is an urgent and decisive issue. We need to prepare for a transforming mission with transforming discipleship. Together towards Life, along with Evangelii Gaudium and Laudato Si', offer paradigm shifts to consider as we envision mission formation with other parameters – with a different theological and ministerial education. Participation in the world is necessary for any true transformative mission: it is there that we learn and practise the true challenges to abundant life for everyone and for all. Practice alone is not enough: we must always question our own praxis, reviewing it in the light of the gospel.     

128 Halftone patterns for printing gray-level images on a laser printer

This paper presents a set of 128 halftone patterns on an 8 × 8 block size. The patterns have been designed to produce an acceptable gray-scale rendition when the halftone is seen from a distance and, at the same time, to allow comparisons to be made among the intensity values of individual pixels at a closer look. A Pascal program is also presented that produces halftones on an HP Laserjet+ laser printer, and sample halftones are shown. Finally, a method is proposed that prevents images digitized with a 4:3 aspect ratio from being distorted when halftones are printed at the usual 1:1 aspect ratio.     

Social anxiety and interpretation of ambiguous smiles

This study investigated whether social anxiety facilitates the discrimination between genuine and ambiguous smiles. Socially anxious (N=20) and nonanxious (N=20) participants categorized as “happy” or “not happy” faces with either (1) a truly happy expression (i.e., happy eyes and a smile), (2) truly nonhappy expressions (e.g., angry eyes and an angry mouth), or (3) blended expressions with a smiling mouth and nonhappy (e.g., angry, sad, etc.) eyes. Results indicated that, relative to nonanxious participants, those high in social anxiety were more likely to judge as “not happy” any blended expression with nonhappy eyes, and they were faster in judging as “not happy” the blended expressions with angry, fearful, or disgusted eyes (but not those with sad, surprised, or neutral eyes). These results suggest, respectively, that social anxiety inhibits a benign interpretation of all the ambiguous expressions with a smile, and speeds up the detection of threatening eyes in such expressions. Importantly, no differences appeared as a function of social anxiety for truly happy or nonhappy faces. This rules out a response-bias explanation, and also reveals that social anxiety does not affect sensitivity in the recognition of prototypical expressions.     

Hemispheric dominance in schizophrenics as determined on extrapyramidal side effects of neuroleptics

Phenomena observed during treatment with neuroleptics were clinically measured in an attempt to determine the difference in vulnerability of the two hemispheres and the relation between this difference and schizophrenic diseases. In the group of systematic schizophrenias the increase in tonus was significantly higher in the dominant hemisphere. This finding is considered a verification of the nosological hypothesis of schizophrenias.     

Civic Education and the Good

It is argued that children need to learn about civic issues intheir education because certain virtues are required for a decently organisedsociety. It is also argued that the school has wide obligations to educate theyoung in civics because it is in their best interests. This is not seen asan encroachment on the privacy of the individual. It is explained that theschool has an obligation to impart knowledge to the young.     

General theories of explanation: buyer beware

We argue that there is no general theory of explanation that spans the sciences, mathematics, and ethics, etc. More specifically, there is no good reason to believe that substantive and domain-invariant constraints on explanatory information exist. Using Nickel (Noûs 44(2):305–328, 2010) as an exemplar of the contrary, generalist position, we first show that Nickel’s arguments rest on several ambiguities, and then show that even when these ambiguities are charitably corrected, Nickel’s defense of general theories of explanation is inadequate along several different dimensions. Specifically, we argue that Nickel’s argument has three fatal flaws. First, he has not provided any compelling illustrations of domain-invariant constraints on explanation. Second, in order to fend off the most vehement skeptics of domain-invariant theories of explanation, Nickel must beg all of the important questions. Third, Nickel’s examples of explanations from different domains with common explanatory structure rely on incorrect formulations of the explanations under consideration, circular justifications, and/or a mischaracterization of the position Nickel intends to critique. Given that the best and most elaborate defense of the generalist position fails in so many ways, we conclude that the standard practice in philosophy (and in philosophy of science in particular), which is to develop theories of explanation that are tailored to specific domains, still is justified. For those who want to buy into a more ambitious project: beware of the costs!
