When enforcing norms for cooperative behavior, human adults sometimes exhibit in-group bias. For example, third-party observers punish selfish behaviors committed by out-group members more harshly than similar behaviors committed by in-group members. Although evidence suggests that children begin to systematically punish selfish behavior around the age of 6 y, the development of in-group bias in their punishment remains unknown. Do children start off enforcing fairness norms impartially, or is norm enforcement biased from its emergence? How does bias change over development? Here, we created novel social groups in the laboratory and gave 6- and 8-year-olds the opportunity to engage in costly third-party punishment of selfish sharing behavior. We found that by age 6, punishment was already biased: Selfish resource allocations received more punishment when they were proposed by out-group members and when they disadvantaged in-group members. We also found that although costly punishment increased between ages 6 and 8, bias in punishment partially decreased. Although 8-y-olds also punished selfish out-group members more harshly, they were equally likely to punish on behalf of disadvantaged in-group and out-group members, perhaps reflecting efforts to enforce norms impartially. Taken together, our results suggest that norm enforcement is biased from its emergence, but that this bias can be partially overcome through developmental change.

Introduction Primary sensory processing is atypical in patients with autism spectrum disorder (ASD) and affects daily functioning. However, the functional connectivity (FC) patterns of primary networks in ASD have not been systematically investigated. Methods Primary networks were defined as four regions of interest (ROIs) in each brain hemisphere. We analyzed ROI‐wise FC in 105 individuals with ASD and 132 typically developing (TD) participants from Autism Brain Imaging Data Exchange I. We calculated the correlation between abnormal FC and clinical scores. Additionally, data from 53 individuals with ASD from our laboratory's two‐site dataset were used to validate the results and assess the effects of sex and age on FC consistency. Results Regarding the ROI‐wise connectivity, significant group differences in FC emerged in several regional pairs, particularly in the primary auditory and somatosensory regions. Abnormal brain regions correlated with clinical symptoms. As age increased, abnormal FC had an initial fast and then slowing development trend, and the abnormal FC in females was higher than that in males. The two‐site dataset results were consistent with those of the multisite dataset in assessing the influence of age and sex on FC. Conclusion Abnormal FC exists in the primary sensory cortex of patients with ASD, which correlates with clinical outcomes and may cause impairments in advanced cognitive functions. In addition, the primary sensory cortex of patients with ASD may undergo excessive growth in the early stages and demonstrate imbalanced development according to sex. These findings may help identify new biomarkers for ASD.

Post-hatch fishes lack a functional gill and use cutaneous surfaces for exchange with the surrounding environment The ionoregulatory hypothesis posits that ionoregulation is the first physiological process to be limited by cutaneous exchange, necessitating its shift to the gills. We hypothesized that the ontogeny of branchial ammonia excretion (Jamm) is coupled to Na⁺ uptake (JNain) in accordance with the current model for Na⁺/NH₄⁺ exchange in freshwater. Using divided chambers, branchial and cutaneous Jamm, JNain and oxygen consumption (MO₂) by larval rainbow trout were assessed. Following hatch, the skin accounted for 97% and 86% of total Jamm and JNain, respectively. Jamm and JNain shifted to tibe gills simultaneously at 15 days post-hatch (dph) and were highly correlated (R² = 0.951) at the gills, but not the skin, over development. Contrastingly, MO₂ shifted significantly later at 27 dph, in agreement with the ionoregulatory hypothesis. Moreover, the mRNA expression and/or enzymatic activity of Rhesus proteins, Na⁺/H⁺-exdianger H⁺-ATPase, Na⁺/K⁺-ATPase and carbonic anhydrase, all key components of the $N{a^ + }/NH_4^ + $-exchange system, increased in the gills over larval development. We propose that the ontogeny of branchial JNain occurs as $N{a^ + }/NH_4^ + $ exchange and provide evidence for a novel element to the ionoregulatory hypothesis, the excretion of potentially lethal metabolic ammonia.

The dynamic field theory predicts that biases toward remembered locations depend on the separation between targets, and the spatial precision of interactions in working memory that become enhanced over development. This was tested by varying the separation between A and B locations in a sandbox. Children searched for an object 6 times at an A location, followed by 3 trials at a B location. Two- and 4-year-olds', but not 6-year-olds', responses were biased toward A when A and B were 9-in. and 6-in. apart. When A and B were separated by 2 in., however, 4- and 6-year-olds' responses were biased toward A. Thus, the separation at which responses were biased toward A decreased across age groups, supporting the predictions of the theory.

An informal discussion for the general reader of the most critical problems of taxation, including an important chapter on the income tax. Originally published in 1948. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This paper explores the connections between colonialism and development in order to understand more clearly how discourses on North-South relations continue to be imbued with the imperial representations that preceded them. Beginning with a concern to examine how anti-racism can inform our understanding of the spaces of international development, the paper interrogates the colonial heritage of development studies and related disciplines and speculates on the possibility and necessity of disciplinary decolonization. Using the specific example of Portuguese imperial discourses of development in the 1950s and the 1960s, and the emergence of the heavily racialized ‘science’ of Lusotropicalism, the paper then examines the importance of deconstruction as a way of understanding the différance between colonialism and development in the Lusophone empire. The paper goes on to examine the particular example of postcolonial Mozambique, exploring the ways in which, between 1975 and 1988, Mozambicans struggled to acknowledge and deal with racism in postcolonial society, particularly in the context of Mozambique’s growing relationship with the World Bank in the mid-1980s. The paper concludes by suggesting that a more direct focus on ‘overdevelopment’ rather than just ‘underdevelopment’ may be one important (if neglected) way forward in ending the silences around ‘race’ and racism in development studies.

One of Jung's most influential ideas has been his view, presented here, that primordial images, or archetypes, dwell deep within the unconscious of every human being. The essays in this volume gather together Jung's most important statements on the archetypes, beginning with the introduction of the concept in \"Archetypes and the Collective Unconscious.\" In separate essays, he elaborates and explores the archetypes of the Mother and the Trickster, considers the psychological meaning of the myths of Rebirth, and contrasts the idea of Spirits seen in dreams to those recounted in fairy tales. This paperback edition of Jung's classic work includes a new foreword by Sonu Shamdasani, Philemon Professor of Jung History at University College London.

The idea of juvenilization as the origin of human existence is based on the premise of the arrested development of the brain. However, evidences presented indicating the overdevelopment of the human brain in contrast to primates oppose the proposed idea.

Since the beginning of the 20th century the Belgian coast has undergone important changes of which an overview is presented here. To determine the view of the Belgian public on the Belgian coast and in order to obtain their opinions and solutions to the problems along the Belgian coast, a questionnaire survey was conducted with a total of 100 respondents divided into five groups, all active in the coastal zone. The five groups included (1) politicians on various levels of authority, (2) coastal entrepreneurs and business people, (3) naturalists and scientists, (4) coastal residents and (5) tourists. Coastal zone problems, as perceived by the different groups, and their solutions are discussed. Former municipalities, in particular, were held responsible for the current coastal problems. Most respondents were skeptic about the application of recent juridical instruments (e.g. the Dune Decree), the structural plans and their power to protect the remaining natural areas. The root of the problems seems to lie in lack of coordination and communication between different authorities responsible for the coastal zone.
