Measuring Motivation Orientation and School Readiness in Children Served by Head Start

Currently, the most widely used direct assessment of motivation orientation for preschoolers has little to no research on its reliability and validity. This study examined the test–retest reliability and concurrent and predictive validity of this direct assessment. Results highlight potential limitations of this measure in capturing motivation orientation in preschoolers from low-income families

Priming God-Related Concepts Increases Anxiety and Task Persistence

Research on the relationship between religiosity and anxiety has been mixed, with some studies revealing a positive relation and other studies revealing a negative relation. The current research used an experimental design, perhaps for the first time, to examine anxiety and task persistence during a stressful situation. Christians and Atheists/Agnostics/Others were primed with God-related or neutral (non-God related) concepts before completing an unsolvable anagram task described as a measure of verbal intelligence. The results revealed that the God-related primes increased both task persistence and anxiousness, which suggests that experimentally induced God-related thoughts caused participants to persist longer on a stressful task, but also to feel more anxious after finishing it. No effect of religious affiliation was found, however, indicating that God-related priming affected Christians and non-Christians in a similar fashion

"Graph Entropy, Network Coding and Guessing games"

We introduce the (private) entropy of a directed graph (in a new network coding sense) as well as a number of related concepts. We show that the entropy of a directed graph is identical to its guessing number and can be bounded from below with the number of vertices minus the size of the graph’s shortest index code. We show that the Network Coding solvability of each specific multiple unicast network is completely determined by the entropy (as well as by the shortest index code) of the directed graph that occur by identifying each source node with each corresponding target node. Shannon’s information inequalities can be used to calculate up- per bounds on a graph’s entropy as well as calculating the size of the minimal index code. Recently, a number of new families of so-called non-shannon-type information inequalities have been discovered. It has been shown that there exist communication networks with a ca- pacity strictly ess than required for solvability, but where this fact cannot be derived using Shannon’s classical information inequalities. Based on this result we show that there exist graphs with an entropy that cannot be calculated using only Shannon’s classical information inequalities, and show that better estimate can be obtained by use of certain non-shannon-type information inequalities

Pacifism and Emotional Arousal

Excerpt: At the age of eighteen, American youths must make an ideological decision about war. Although most probably perceive selective service registration as little more than a rite of passage, others struggle with the ethics of military service and options of conscientious objection. What can be said of youths who decide, for moral and religious reasons, that they will not be involved in warfare? To date, no descriptive studies have been reported that address this question. Previous studies on pacifism focus on the likelihood of pacifism in eliciting cooperation (Gruder & Duslak, 1973; Marwell & Schmitt, 1973) or aggression (Borden, 1975; Borden & Taylor, 1976; Fitz, Kimble, & Heidenfelder, 1979; Fitz, Marwit, & Gerstenzang, 1983; Kimble, Fitz, Onorad, 1977; Mander & Gaebelein, 1977). Moreover, these studies have typically recruited participants who were assigned pacifistic strategies rather than recruiting those with pre-existing pacifistic inclinations

Proof phenomenon as a function of the phenomenology of proving

Kurt Gödel wrote (1964, p. 272), after he had read Husserl, that the notion of objectivity raises a question: “the question of the objective existence of the objects of mathematical intuition (which, incidentally, is an exact replica of the question of the objective existence of the outer world)”. This “exact replica” brings to mind the close analogy Husserl saw between our intuition of essences in Wesensschau and of physical objects in perception. What is it like to experience a mathematical proving process? What is the ontological status of a mathematical proof? Can computer assisted provers output a proof? Taking a naturalized world account, I will assess the relationship between mathematics, the physical world and consciousness by introducing a significant conceptual distinction between proving and proof. I will propose that proving is a phenomenological conscious experience. This experience involves a combination of what Kurt Gödel called intuition, and what Husserl called intentionality. In contrast, proof is a function of that process — the mathematical phenomenon — that objectively self-presents a property in the world, and that results from a spatiotemporal unity being subject to the exact laws of nature. In this essay, I apply phenomenology to mathematical proving as a performance of consciousness, that is, a lived experience expressed and formalized in language, in which there is the possibility of formulating intersubjectively shareable meanings
