The Artificial Adaptive Systems (AAS) are theories with which generative algebras are able to create artificial models simulating natural phenomenon. Artificial Neural Networks (ANNs) are the more diffused and best-known learning system models in the AAS. This article describes an overview of ANNs, noting its advantage…

The proportion of eighth graders in United States public schools enrolled in algebra or a more advanced mathematics course doubled between 1990 and 2011. This article uses Early Childhood Longitudinal Study's Kindergarten Cohort data to consider the selection process into advanced middle school mathematics courses and…

Acculturation and acculturative stress are examined as predictors of alcohol use among Asian immigrants, using the 2004 National Latino and Asian Americans Survey (NLAAS). Separate regression analyses were conducted for Chinese (n = 600), Filipino (n = 508), and Vietnamese (n = 520) immigrants. Alcohol use varied for t…

Grounded theory was employed to elucidate how public health nurses (PHNs) develop therapeutic relationships with vulnerable and potentially stigmatized clients, specifically, single mothers living in low-income situations. We named the emerging theoretical model Targeting Essence: Pragmatic Variation of the Therapeutic…

This study's primary goal was to evaluate the use of performance feedback procedures delivered to a classroom team to increase daily data collection. Performance feedback (PFB) was delivered to four classroom teams responsible for the daily collection of data representing student performance during prescribed instructi…

Informed consent (IC) to treatment honors patient autonomy and bodily integrity. Yet, it is a leading reason for patient litigation, it has not been examined from discursive or theoretical perspectives, and its sociohistorical context is ignored. In a previous analysis of American IC law and the IC literature, structur…

Among the various chronic diseases, cancer is the leading cause of death in Hong Kong. This article presents the process of how cancer patients are being enabled and strengthened to overcome powerlessness based on the interview findings of 12 participants. Interviews were analyzed using constant comparison. The basic s…

BACKGROUND: International visitors to tropical Australia may be exposed to health and safety problems. Because they are younger, stay longer and participate in more activities, backpackers have a greater exposure to such problems than other visitors. METHOD: The study's aim was to determine how many backpackers experi…

Giving the rear wheels of manually propelled wheelchairs negative camber (by angling them such that the bottoms of the wheels are farther apart than the tops) has become increasingly popular, especially among active users. This study's purpose was to evaluate how changing camber affects a wheelchair's mechanics and the…

In 2 experiments, the effects on participants' memory and confidence of repeatedly describing a videotaped crime and of the opportunity to review a previous description were investigated. E. Scrivner and M. A. Safer (1988) demonstrated that witnesses' successive attempts to describe such events can lead to the recall o…

We operationalized and tested E. R. Hilgard's (1973a, 1977b) neodissociation theory. His work suggested that the dissociation necessary for experiencing hypnotic phenomena may be attributable to a general capacity for dissociation that should be measurable outside of the domain of hypnosis. We used several types of ope…

This study's objectives were to test the emotional stability and self-perceptions of Holocaust survivors' offspring (HSO) and to investigate how HSO perceive their parents. It was assumed that the investigation of these two issues would broaden our understanding of the mediating processes through which the psychologica…

The study's purpose was to assess the effectiveness of an activity-centered health education curriculum designed for regular students on the general health beliefs of special education students. As part of an entire school system evaluation, 92 Learning Disability students and 142 Learning Limitation students were rand…

A test of electrocardiogram diagnostic skills in the form of a ten-slide presentation of six-second rhythm strips was administered to 25 emergency department nurses, 23 intensive care unit (ICU) nurses, 34 cardiac technicians (CRT, EMT) and 37 physicians. The ICU nurses had the best performance overall. Physicians had…

BACKGROUND: Survivors of suicide loss (suicide survivors) are recognized as an at-risk population for several psychiatric complications, including complicated grief (CG) and suicide ideation (SI). Recent studies have emphasized the contribution of interpersonal factors, such as thwarted belongingness and perceived burd…

BACKGROUND: Risk stratification is paramount for treatment of patients with chronic Chagas disease (CCD). The exercise stress test (EST) may be useful in the risk stratification of patients with this condition, but few studies have been performed in patients with CCD. METHODS: This was a longitudinal, retrospective co…

INTRODUCTION: Sensitivity and specificity of colposcopy vary greatly between studies and efficacy in clinical studies seldom corresponds with effectiveness in a real-life setting. It is unclear whether colposcopists' experience affects assessment; studies show divergent results. The study's objective was to investigate…

Septorhinoplasty (SRP) is one of the most commonly performed procedures worldwide. There is a recognized debate about the impact of nasal surgery on olfactory function (OF). The study's objective was to assess the effect of SRP on late postoperative OF. A comprehensive review and meta-analysis were employed to assess O…

With a focus on melatonin, a recent paper in the Journal investigated the hypothesis that endometrial cancer might be associated with the duration, and ultimately, amount of sleep. The authors found that "[s]elf-reported sleep duration may not adequately represent melatonin levels." The authors also concluded that ther…

Attrition is a particular concern in studies examining the efficacy of a treatment for Alzheimer disease. Analyzing reasons for withdrawal in Alzheimer studies is crucial to ruling out attrition bias, which can undermine a study's validity. In contrast, attrition in studies using repetitive transcranial magnetic stimul…
