Subitizing And Counting: Preattentive And Attentive Processing In Visual Enumeration
Subitizing, the process of visual enumeration when there are fewer than four items, is rapid (40-100 msec/item), accurate and effortless. In contrast, counting, the process of enumerating more than four items is comparatively slow (250-350 msec/item), effortful and error prone. Why does this occur? In this paper an attempt is made to incorporate subitizing and counting into a general theory of visual perception and spatial attention, as espoused by Marr(1982), Ullman(1984), and Treisman(1988). In particular, it is argued that the rapid apprehension of number in the 1-4 range is parasitic on a preattentive limited capacity mechanism that individuates feature clusters by assigning spatial reference tokens or FINSTs to them(Pylyshyn, 1989). These spatial reference tokens permit the identities of a small number of items to be maintained though their properties and retinal coordinates change, a capability important for directing the attentional focus and coordinating eye and hand movements. If the subitizing process makes use of such preattentive information, then it should not be possible to subitize when spatial attention is required to compute spatial relations, resolve the item as a whole or discern items to be counted from other distractor items. Thus, it was predicted that the slope of the latency function in the 1-4 range should approximate that of the 5+ range if spatial attention is required to perform a particular enumeration task. In contrast, it was predicted that subitizing should be possible when preattentive information could be used to distinguish the items to be counted from one another, or from other distractor items. Therefore, it was predicted that there should be discontinuities in slopes of the latency function between the 1-4 and 5+ range, as shown by deviations from linearity in trend analysis.;Five experiments were performed. In the first, subjects were shown capable of subitizing when the task was to enumerate items of a particular colour though they were not capable of subitizing when the task was to enumerate items that were connected to each other by a contour. This result was expected because spatial attention is presumed necessary to compute the connected relation(Ullman, 1984; Jolicoeur, 1988). The second pair of experiments showed that though subjects can easily subitize when items are defined by groups of contours instead of simple edge points, they cannot easily enumerate such items if they are concentric, as would be predicted given that preattentive grouping processes would cluster all the contours into a unit in this case. The fourth and fifth experiments show that subjects can subitize certain target items in a field of distractors, but only if the property that differentiates targets from distractors is a feature, or a property thought to emerge preattentively. In situations where attention is required to form a unified object description by joining different dimensions (e.g., colour and orientation), or by joining different parts of an item (e.g., an O and a stem to form a Q), subitizing was not apparent. Overall, these experiments suggest that the subitizing process relies on preattentive information
Lead in Our Communities: A Chemical, Sociological and Public Health Analysis
Childhood lead poisoning is still of great concern within the United States, particularly in underprivileged communities that are often home to minority populations. Oneida County, New York has one of the highest instances of childhood lead poisoning per capita in the entire state. There are many pathways to lead exposure. This research looked to confirm the existence of a secondary lead smelter in Utica, New York through the analysis of soil samples and historical documents. It was hypothesized that the site of a former secondary lead smelter, and areas surrounding it, would exhibit high concentrations of lead. Soil samples were prepared for analysis using Environmental Protection Agency guidelines for the acid digestion of soil, after which atomic absorption spectroscopy was used to analyze the samples for concentration of lead content. Lead that is off put into the environment due to the operation of lead smelters shows secondary markers of increased cadmium concentration. The Cornell Nutrient Analysis Laboratory (CNAL) provided secondary analysis of all samples for lead and cadmium concentrations. The historical and chemical findings support the existence of a former lead smelter in downtown Utica, New York. This research has significant implications. One of the largest municipal housing complexes in the city of Utica, New York was located adjacent to the lot of the smelter, with the two coexisting for nine years. Examining various pathways to lead exposure is necessary to inform and shape the response to the public health issue of lead poisoning

A culturally relevant symbol: Participant engagement in a volunteer tourism music-conservation youth education program
Abstract
Volunteer-led travel educational programs focus on diverse community initiatives. Daraja Music Initiative (DMI), a US-Tanzanian nonprofit, indicates they are “providing an interdisciplinary approach to sustainability through music...by actively engaging students and the community with the power of music” (DMI, 2018). Thirteen interviews and four focus groups were conducted with volunteer tourists, community members and youth, during summer 2017 in Moshi, Tanzania, in order to seek perspectives on what engagement means and explore the concept of engagement through a new theoretical framework. Findings suggest engagement in a volunteer tourism program (connection, communication and hope) is through a culturally relevant symbol, and has linkages to the study of semiotics (Mick, 1986). Study implications can be beneficial for community development and collaborative planning, as well as contribution to engagement theory, sustainable tourism and volunteer tourism research.

O presente trabalho faz parte de um projeto coordenado pelo Sebrae-DF, intitulado Desenvolvimento da Horticultura em Planaltina e Áreas Adjacentes com a participação da Embrapa Hortaliças e da Emater-DF, juntamente com instituições de ensino, outras entidades ligadas so Sistema S e associações de categorias profissionais. Tem por objetivo promover o desenvolvimento da produção olerícola na região de Planaltina visando à melhoria da qualidade de vida e renda dos agricultores com aumento nas vendas e faturamento, redução das perdas dos produtos e fortalecimento da cooperativa de agricultores da região.bitstream/item/102931/1/doc-132.pd
Die Einsatz Der Medien “ Tangga Pertanyaan” Im Lernen Der Sprechfertigkeit Der Schüler Von Den Klasse XII IPA 1 SMA Negeri 8 Kediri
The formulation of the problem in this research is how the media use the stairs question in learning German language speaking skills and students' response to the use of media in learning the skills ladder question speak German in class XII IPA 1 SMAN 8 Kediri. The purpose of this study was to describe the use of media in learning the skills ladder question speaks German and response class XII IPA 1 SMA Negeri 8 Kediri against the use of media Stairs Question . This study is a qualitative study using observation sheets and questionnaires as a research instrument. Observation sheet used to determine the activity of the students during the learning process takes place , while the questionnaire is used to determine the students' response to the use of media Stairs Question in learning speaking skills . The results of this study is the use of media in teaching skills ladder question speaks to the media using Ladder Question goes well visible from the activity and the positive response shown by the students during the learning process takes place.
