Abstract We investigate the relationship between climatic and demographic events in Korea during the Chulmun period (10,000–3,500 cal. BP) by analyzing paleoenvironmental proxies and 14C dates. We focus on testing whether a cooling climate, and its potential impact on millet productivity around 4,500 cal. BP triggered the population decline observed in the archaeological record. We employ a Bayesian approach that measures the temporal relationship between climatic events and change-points in the rate of growth in human population as inferred by radiocarbon density. Our results do not support the climate-induced population decline hypothesis for three reasons. First, we could not determine that the cooling climatic event necessarily preceded the reversal point in population growth rate as inferred by the radiocarbon record. Second, we did not find evidence showing a significant reduction of millet-associated dates occurring during the cooling climate. Third, we detected a spatially differentiated pattern of decline in inland and coastal regions, indicating that the cooling climate did not impact all populations equally. We highlighted the long tradition of mobility-based subsistence strategy in the coastal region as a potential factor contributing to the spatial differences.

The Relationship

Although many children are referred with difficulties in both their speech and their language, the literature offers relatively little guidance on their therapy. Should clinicians treat these difficulties independently? Or should treatment depend on the potential impact of one domain on the other? This study aimed to investigate the relationship between speech and morphosyntax in treatment for a 5-year-old boy, B, with speech and language difficulties. Therapy targeted the production of regular past tenses and plurals. B had the necessary phonology for the former but not the latter. Therapy therefore directly targeted production of the past tense but targeted plurals by treating the production of the necessary phonology. After therapy, B successfully produced regular past tenses for both treated and untreated verbs. Irregular verbs did not improve. Treatment for production of word-final /s/ was successful and generalized to untreated words but not to the production of /s/ in initial or medial positions. Plurals formed by adding /s/ but not those by adding /z/ benefited. Similar treatment for production of word-final /z/ was also successful and appeared to generalize to words with /z/ in initial and medial positions. However, although plurals were now marked, they were usually realized as [dz]. The results of this single-case study demonstrate that intervention for children with speech and language impairments should take account of the aspects of speech and morphology that are impaired, and the ways these may impact on each other.

AbstractWe investigate the relationship between climatic and demographic events in Korea during the Chulmun period (10,000–3,500 cal. BP) by analyzing paleoenvironmental proxies and 14C dates. We focus on testing whether a cooling climate, and its potential negative impact on millet productivity around the mid 5th-millennium cal. BP, triggered the population decline suggested by the archaeological record. We employ a Bayesian approach that estimates the temporal relationship between climatic events and change-points in the rate of growth in human population as inferred from radiocarbon time frequency data. Our results do not support the climate-induced population decline hypothesis for three reasons. First, our Bayesian analyses suggest that the cooling event occurred after the start of the population decline inferred from the radiocarbon time–frequency record. Second, we did not find evidence showing a significant reduction of millet-associated dates occurring during the cooling climate. Third, we detected different magnitudes of decline in the radiocarbon time–frequency data in the inland and coastal regions, indicating that the even if cooling episodes were ultimately responsible of these population ‘busts’, their impact was most likely distinct between these regions. We discuss our results highlighting the long tradition of mobility-based subsistence strategy in coastal regions as a potential factor contributing to the regional differences we were able to detect.

Regular Physical Exercise

The benefits of regular physical exercise do not only concern physical wellness, but also seem to influence cognitive function. Multiple pathways have been suggested to explain the potential impact of regular exercise on cognition, from cellular, molecular and structural adaptations, to behavioral and social consequences of exercising). In this review, we propose interoception as a potential factor involved in the relationship between cognition and physical exercise. We first define and describe interoception, its dimensions and properties, to then, summarize the current research regarding interoception and cognition. Third, we examine the bidirectional role existing between interoception and physical activity. Finally, we lay out the evidence that leads us to consider the reciprocal relationship between exercise, cognition and interoception.

The Relationship

This article explores why landscape is a crucial element in researching the relationship between environment and well-being. The main point we make is that human social agents are embedded in particular landscapes, and it is in landscapes that environmental changes are experienced, which can have implications for well-being. We draw from a variety of perspectives on landscape that understands a fundamental creative relation between humans and landscape and recent developments in neo-materialism theorising. Landscape is understood here as an assemblage of different forms of matter, animate and inanimate objects, as well as symbolic and cultural processes. A case study is also presented to indicate how landscape can be studied in relation to environment and change. Using the conceptual ideas laid out in the first section of the article, we analyse landscape, environment and well-being in Xuan Thuy National Park in North Vietnam. The area is part of a precarious coastal region where extreme weather events have impacted on the well-being of both humans and other matter. This article concludes with suggestions on the use of this landscape approach in researching environment and well-being.

Purpose This exploratory study aimed to investigate the potential impact of sentence-level comprehension and sentence-level fluency on passage comprehension of deaf students in elementary school. Method A total of 159 deaf students, 65 students ( M age = 13.46 years) in Grades 3 and 4 and 94 students ( M age = 14.95 years) in Grades 5 and 6, were assessed for nonverbal intelligence, vocabulary knowledge, sentence-level comprehension, sentence-level fluency, and passage comprehension. Group differences were examined using t tests, whereas the predictive and mediating mechanisms were examined using regression modeling. Results The regression analyses showed that the effect of sentence-level comprehension on passage comprehension was not significant, whereas sentence-level fluency was an independent predictor in Grades 3–4. Sentence-level comprehension and fluency contributed significant variance to passage comprehension in Grades 5–6. Sentence-level fluency fully mediated the influence of sentence-level comprehension on passage comprehension in Grades 3–4, playing a partial mediating role in Grades 5–6. Conclusions The relative contributions of sentence-level comprehension and fluency to deaf students' passage comprehension varied, and sentence-level fluency mediated the relationship between sentence-level comprehension and passage comprehension.

The article explores the political effects of popular consultations as a means of direct democracy in struggles over mining. Building on concepts from participatory and materialist democracy theory, it shows the transformative potentials of processes of direct democracy towards democratization and emancipation under, and beyond, capitalist and liberal democratic conditions. Empirically the analysis is based on a case study on the protests against the La Colosa gold mining project in Colombia. The analysis reveals that although processes of direct democracy in conflicts over mining cannot transform existing class inequalities and social power relations fundamentally, they can nevertheless alter elements thereof. These are for example the relationship between local and national governments, changes of the political agenda of mining and the opening of new spaces for political participation, where previously there were none. It is here where it’s emancipatory potential can be found.

This article tackles the relationship between Turkish-Belgian families with the Flemish society, within the specific context of their experiences with early childhood education and care (ECEC) system in Flanders. Our findings are based on a focus group with mothers in the town of Beringen. The intercultural dimension of the relationships between these families and ECEC services is discussed using the Interactive Acculturation Model (IAM). The acculturation patterns are discussed under three main headlines: language acquisition, social interaction and maternal employment. Within the context of IAM, our findings point to some degree of separationism of Turkish-Belgian families, while they perceive the Flemish majority to have an assimilationist attitude. This combination suggests a conflictual type of interaction. However, both parties also display some traits of integrationism, which points to the domain-specificity of interactive acculturation.
