Digital media availability has surged over the past decade. Because of a lack comprehensive measurement tools, this rapid growth in access to digital is accompanied by scarcity research examining family context and sociocognitive outcomes. There also little cross-cultural families with young children. Modern are mobile, interactive, often short duration, making them difficult remember when caregivers respond surveys about use. The Comprehensive Assessment Family Media Exposure (CAFE)...
During the unprecedented coronavirus disease (COVID-19) crisis, virtual education activities have become more prevalent than ever. One activity that many families incorporated into their routines while at home is storytime, with teachers, grandparents, and other remote adults reading books to children over video chat. The current study asks how dialogic chat compares traditional forms of book in promoting story comprehension vocabulary learning. Fifty-eight 4-year-olds (Mage = 52.7, SD 4.04,...
The question of whether screen time, particularly time spent with social media and smartphones, influences mental health outcomes remains a topic considerable debate among policy makers, the public, scholars.Some scholars have argued passionately that may be contributing to an increase in poor psychosocial functioning risk suicide, teens.Other contend evidence is not yet sufficient support such dramatic conclusion.The current meta-analysis included 37 effect sizes from 33 separate studies.To...
Professional advocacy associations such as the American Psychological Association (APA) and Academy of Pediatrics commonly release policy statements regarding science behavior. Policymakers general public may assume that reflect objective conclusions, but their actual fidelity in representing remains largely untested. For example, recent decades, related to media effects have been released with increasing regularity. However, they often provoked criticisms do not adequately state on effects....
The relationship between the development of hydraulic agriculture and formation sociopolitical hierarchies is a major issue in studies evolution early civilizations Basin Mexico elsewhere. Previous explanations agricultural intensification have emphasized population pressure effects settlement nucleation distance to markets. Neither factor, however, adequately explains shift farming at relatively low levels arid semi‐arid environments. This paper attempts demonstrate that risk crop failure...
Abstract We are researching the interaction between rule and ontology layers of Semantic Web, by comparing two options: 1) using OWL its extension SWRL to develop an integrated ontology/rule language, 2) layering rules on top with RuleML OWL. Toward this end, we developing SWORIER system, which enables efficient automated reasoning ontologies rules, translating all them into Prolog adding a set general that properly capture semantics have also enabled user make dynamic changes fly, at run...
During the Classic Period, Teotihuacan was an economic centre of central Mexico, but little is known about development this system. This paper presents a pilot study in multi‐method analysis Formative Period (1500/1400 bc – ad 150) ceramics from Valley. Pottery characterized by instrumental neutron activation analysis, laser ablation inductively coupled plasma mass spectrometry, thermal ionization spectrometry and petrography. It appears that most pottery made local raw materials differ...
Abstract Intensive agriculture was a key feature in the development of early complex societies Basin Mexico. In this paper, I review theoretical underpinnings archaeological understandings change, its relationship to culture and how these perspectives have shifted between top-down bottom up perspectives. Next examine current knowledge intensive within dynamic context Formative or Preclassic period. The paper concludes with discussion our models theories interplay political economy explain...
Although textiles were important commodities in the Aztec political economy, it is widely held that textile production did not involve organized workshops. In late 1960s, Charlton (1971, 1981) found a concentration of large spindle whorls at city-state capital Otumba he interpreted as remains maguey-fiber workshop. A subsequent survey and surface collections made by Project discovered additional concentrations associated with fiber-processing tools manufacturing debris provide substantial...
Obsidian and ceramic artifacts from the Otumba project were analyzed by instrumental neutron-activation analysis. Sources for obsidian determined comparison to a databank of Central Mexican source analyses. Ceramic sources series reference groups Basin Mexico with raw material samples. lapidary workshop (Operation 11) comes predominantly Pachuca sources. There is also an unknown compositional profile present among artifacts. This may derive not-yet-sampled flow within one several nearby...
Otumba is one of a few Late Aztec-period city-states in the Basin Mexico whose central city or town not obscured by post-Conquest occupation. Long-term research there began early 1960s, with more recent fieldwork between 1987 and 1989, has been complemented intensive laboratory technical analyses that are still underway. Traditional typological have aided neutron activation providing strong evidence economic linkages city-state raw material sources, as well tribute market distribution...
Abstract For several decades, little research has been directed towards understanding the beginnings of complex society in Teotihuacan Valley. Recent archaeological investigations at Early–Middle Formative site Altica provide a fresh perspective on dating initial establishment agricultural villages, early social and economic differentiation, development intra-and interregional exchange networks to test comparative models political economy.
Abstract Siblings offer a unique context for practising skills such as executive function (EF). Further, siblings are influential agents in parenting practices, which may, turn, be related to EF. The current study investigated the extent presence of sibling is parent‐reported EF preschoolers and whether indirectly through global practices. Participants included children 30 60 months old their caregivers ( n = 505). Caregivers indicated that target were predominately White 354, 72%) African...
Abstract The Altica Project that began in 2014 is an important step addressing over two decades of limited problem-oriented research at Formative sites the Basin Mexico. Through this research, we demonstrate earliest known settled village Teotihuacan Valley and one only first-farming Mexico has not been engulfed by urban sprawl City. It represents northward spread life a time people region were transitioning from mobile foraging lifestyle to more reliant on food production. Despite its small...
Abstract We explore the relationship between long-distance pottery trade and formation of Early Middle Formative style horizons in Mesoamerica. A sample 1,154 ceramics mostly from contexts central Mexican highlands was irradiated at University Missouri Research Reactor with a subsample (n = 313) for petrographic analysis. conclude that: (1) most sites regions display more than one process making pottery; (2) there is small amount intraregional exchange among sites, southeastern Basin Mexico...
The Black Mesa Archaeological Project has been conducting field investigations and archaeological research in northeastern Arizona since 1967. work is contracted for by Peabody Coal Company order to comply with federal, state, tribal statutes. longevity of the project, as well its size complexity, affords a unique opportunity evaluate refine research, project administration, legal compliance procedures. In most situations, clear advantages have resulted from opportunities learn project's...
Locating and dating remains of pre-Aztec hydraulic agricultural systems in the Basin Mexico with conventional reconnaissance survey methods is problematic. Near-infrared aerial photographs have revealed buried linear features resembling irrigation canals several areas including Tlajinga section pre-Columbian city Teotihuacán. Excavations confirmed that are prehispanic floodwater canals. The most recent ones date to Late Aztec period; earliest were probably constructed Teotihuacán times...
