Adverse Childhood

Introduction: The present study explores the association of adverse childhood experiences with impulsivity and functional identity among Pakistani adults. Methods: In this cross-sectional study, 260 Pakistani medical students aged 18 and above were approached. A consent form, a questionnaire on sociodemographic characteristics, and an English versions of the Adverse Childhood Experiences (ACE) scale, Functions of Identity scale (FIS) and Barratt’s Impulsiveness Scale (BIS-11) was employed in this study. All data were analyzed in SPSS v. 20. Results: A total of 122 (52.6%) of respondents had experienced at least one adverse childhood experience. According to linear regression analysis, ACE scores were significantly associated with increasing age, increasing order in birth, lower scores on functional identity structure and non-planning impulsivity, and higher scores on future (functional identity) and motor impulsivity. Conclusions: A high proportion of Pakistani medical students reported adverse childhood experiences, which lead to impulsive behaviors and poor functional identities.

What Matters

AbstractWhich task is easier, doing arithmetic problems of specified form for some specified duration, or carrying a bucket of specified weight over some specified distance? If it is possible to choose between the “more cognitive” task and the “more physical” task, how are the difficulty levels of the tasks compared? We conducted two experiments in which participants chose the easier of two tasks, one that involved solving addition or multiplication problems (Experiment 1) or addition problems with different numbers of addends (Experiment 2) for varying amounts of time (in both experiments), and one that involved carrying a bucket of different weights over a fixed distance (in both experiments). We found that the probability of choosing to do the bucket task was higher when the bucket was empty than when it was weighted, and increased when the cognitive task was harder and its duration grew. We could account for the choice probabilities by mapping the independent variables onto one abstract variable, Φ. The functional identity of Φ remains to be determined. It could be interpreted as an inferred effort variable, subjective duration, or an abstract, amodal common code for difficulty.

Abstract Tree retention after forest harvest is often used to enhance biodiversity in forests that are otherwise managed using even-aged systems. It remains unclear to what extent scattered trees and residual patches (i.e., retained structures) actually facilitate recolonization of species in logged areas. For assessing recolonization benefits, it is necessary to consider both survival in retained structures postharvest and recolonization in cleared areas. We conducted a literature review to assess recolonization responses of birds, mammals, reptiles, amphibians, vascular plants, invertebrates, lichens/bryophytes, and mycorrhizal fungi. The clearest benefits of retention were for poorly dispersing plants. Seed dispersal type may be a key life-history trait relative to effectiveness of recolonization, with animal-dispersed seeds having the greatest dispersal range. We found that lichens/bryophytes are likely not dispersal limited (with possible exceptions) but are slow growing and require the development of moist microsite conditions. Significant literature gaps exist for amphibians, nonvolant invertebrates, and mycorrhizal fungi. Overall, recolonization success postharvest is taxon specific, where the benefits of implementing retention systems will depend on the region and species within that region. Species that require a long growth period (some lichens) or are poor dispersers (some herbaceous species) may benefit more from the creation of forest reserves than from retention practices.
