Intuition versus Formalization: Some Implications of Incompleteness on Mathematical Thought

Intuition versus Formalization: Some Implications of Incompleteness on Mathematical Thought

Date: August 1994
Creator: Lindman, Phillip A. (Phillip Anthony)
Description: This paper describes the tension between intuition about number theory and attempts to formalize it. I will first examine the root of the dilemma, Godel's First Incompleteness Theorem, which demonstrates that in any reasonable formalization of number theory, there will be independent statements. After proving the theorem, I consider some of its consequences on intuition, focusing on Freiling's "Dart Experiment" which is based on our usual notion of the real numbers as a line. This experiment gives an apparent refutation of the Axiom of Choice and the Continuum Hypothesis; however, it also leads to an equally apparent paradox. I conclude that such paradoxes are inevitable as the formalization of mathematics takes us further from our initial intuitions.

Intuitive Eating Scale: An Examination Among Adolescents

Intuitive Eating Scale: An Examination Among Adolescents

Date: December 2011
Creator: Dockendorff, Sally A.
Description: Intuitive eating assesses the degree to which individuals eat based on physiological cues rather than emotional or situational cues. The Intuitive Eating Scale was initially developed using college women. This study extends the work of Tylka and reports on the psychometric evaluation of the Intuitive Eating Scale (IES) in a sample of 515 middle school boys and girls. Exploratory factor analysis uncovered 4 factors: unconditional permission to eat, eating for physical rather than emotional reasons, trust in internal hunger/satiety cues and awareness of internal hunger/satiety cues; confirmatory factor analysis suggested that this 4-factor model adequately fit the data after 4 items with low factor loadings were deleted. Supporting its construct validity, IES scores were negatively related to body mass index, body dissatisfaction, negative affect, pressure for thinness, and internalization of the thin ideal, and were positively related to satisfaction with life, and experiencing greater positive affect.

Inventions, Dreams, Imitations

Inventions, Dreams, Imitations

Date: August 1997
Creator: Gatlin, Charles Morgan
Description: Eight short selections of fiction. "Inventions" consists of two invented creation myths. The three stories in "Dreams" are fantasy tales set in a common dream-world. The selections in "Imitations" are neither fantasy nor science fiction: "Time's Tapering Blade" is an experiment in form; "The Wake" concerns a group of friends dealing with a death; and "Janie, Hold the Light" is based on stories from the author's family about Christmas during the depression of the 1930's.

Investigating incidental vocabulary acquisition in ESL conversation classes.

Investigating incidental vocabulary acquisition in ESL conversation classes.

Date: December 2009
Creator: Mohamed, Ayman Ahmed Abdelsamie
Description: This study examined incidental receptive and productive vocabulary gains within conversation-class interactions. Eleven Mexican learners of English attended four videotaped conversation lessons where 40 target words were incorporated in different types of exposure. Stimulated recall interviews with students highlighted the effect of cognates, learners' access to passive vocabulary, and use of their vocabulary knowledge in learning related words. Posttests revealed a correlation between frequency and receptive/productive gains. Mean scores showed that words mentioned with synonyms were learned most often, followed by task-essential words and last those mentioned without explanation. A two-way ANCOVA revealed main effects for cognates, and a statistical interaction between cognate status and types of exposure. A statistical correlation was found between receptive and productive gains. Aptitude scores correlated with productive gains but not with receptive gains. The results provide implications for ESL teachers who consider incidental learning of vocabulary within their conversation lessons.

Investigating Molecular Structures: Rapidly Examining Molecular Fingerprints Through Fast Passage Broadband Fourier Transform Microwave Spectroscopy

Investigating Molecular Structures: Rapidly Examining Molecular Fingerprints Through Fast Passage Broadband Fourier Transform Microwave Spectroscopy

Date: May 2011
Creator: Grubbs, Garry Smith, II
Description: Microwave spectroscopy is a gas phase technique typically geared toward measuring the rotational transitions of Molecules. The information contained in this type of spectroscopy pertains to a molecules structure, both geometric and electronic, which give insight into a molecule's chemistry. Typically this type of spectroscopy is high resolution, but narrowband ≤1 MHz in frequency. This is achieved by tuning a cavity, exciting a molecule with electromagnetic radiation in the microwave region, turning the electromagnetic radiation o, and measuring a signal from the molecular relaxation in the form of a free induction decay (FID). The FID is then Fourier transformed to give a frequency of the transition. "Fast passage" is defined as a sweeping of frequencies through a transition at a time much shorter (≤10 s) than the molecular relaxation (≈100 s). Recent advancements in technology have allowed for the creation of these fast frequency sweeps, known as "chirps", which allow for broadband capabilities. This work presents the design, construction, and implementation of one such novel, high-resolution microwave spectrometer with broadband capabilities. The manuscript also provides the theory, technique, and motivations behind building of such an instrument. In this manuscript it is demonstrated that, although a gas phase technique, solids, liquids, ...

Investigating patterns among demographics, identification practices, interventions, and educational outcomes for students with serious emotional disturbance.

Investigating patterns among demographics, identification practices, interventions, and educational outcomes for students with serious emotional disturbance.

Date: August 2003
Creator: Gonzalez, Christine
Description: This study explored potential patterns of association among the demographic characteristics, identification practices, educational interventions, and educational outcomes for students with serious emotional disturbance (SED) as well as specifically investigated the impact of age at identification with SED and the presence of co-occurring disabilities. Data was gathered from the educational records of students with SED in seven rural to semi-rural districts in Texas. Demographic information included gender, ethnicity, age at identification with SED, and identification with co-occurring disabilities. Identification variables that were investigated include the five federal qualifying criteria for SED, IQ score, and BASC and/or CBCL scores. Intervention variables that were explored included placement setting, restrictiveness of placement setting, type of related services provided, parental attendance at multidisciplinary team meetings, number of multidisciplinary team meetings, and total time spent in special education as a student with SED. Outcome variables that were examined included achievement levels in reading and math, attendance, special education status, and grade retention. Results suggested that earlier identification with SED is related to placement in less restrictive settings, achievement within two years of grade level in reading, and lower average number of absences. The presence of co-occurring disabilities in addition to SED is associated with placement ...

Description: Postpartum depression (PPD) is a major health problem that affects many women worldwide. In Egypt, PPD is neglected despite the expected high prevalence rate among women during the transition period after the Egyptian revolution. This research investigated the prevalence, risk factors, and interventions of postpartum depression in southern rural Egypt. Interviews were conducted with 57 participants recruited from public and private hospitals. Questionnaires and the Arabic version of the Edinburgh Postnatal Depression Scale were administered. The prevalence of PPD is 73.7%. PPD is associated with low income and age at childbirth. Most participants regarded screening mothers after childbirth for PPD as effective; in comparison to, antidepressants that were regarded by most participants as ineffective. Women in southern rural Egypt prefer high number of pregnancies, so investigating the influence of sertraline, an antidepressant medication, on female hormones becomes important. In this research, fathead minnows were exposed to 3 and 10 ppb sertraline for 7 days. Real-time Polymerase Chain Reaction was used to detect the change in gene expression of the Follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Results showed that a down regulation at the 10 ppb was evident on the LH and to a lesser extent on FSH. Our results ...
