Abstract In the third study of this series, we examined how circles with a suspended aid would vary depending of the gymnast's level of expertise. We analysed circles with the aid performed by three groups of eight gymnasts: expert, intermediate, and developing groups. The gymnasts for the expert and intermediate ...

This 5-wave longitudinal study, which included 1,313 Dutch adolescents, examined the development of peer crowd identification in relation to changes in problem behaviors. Adolescents from 2 age cohorts annually reported their identification with 7 peer crowds and their levels of internalizing and externalizing problem behaviors. Univariate latent growth curve analyses ...

ACCESSIBLE SUMMARY: •  The purpose of this study was to describe the role of inclusiveness in lessening the pain of parents death in adolescents orphaned by AIDS. •  Data were derived from 15 AIDS orphans between the ages of 14 and 18 years. •  The method used was focus groups ...

Particle swarm optimization (PSO) has been shown as an effective tool for solving global optimization problems. So far, most PSO algorithms use a single learning pattern for all particles, which means that all particles in a swarm use the same strategy. This monotonic learning pattern may cause the lack of ...

Multiple risk factors contribute to suicides; however, patterns of co-occurrence among these factors have not been fully identified. To assess patterns of known suicide-related risk factors, classify suicide decedents by these patterns, track class proportions during a 6-year period, and characterize decedents across the classes to help focus prevention strategies. ...

ABSTRACT: BACKGROUND: Constant high-level numbers of railway suicides indicate that prevention strategies against railway suicides are urgently needed. The main question of the present study was whether pre-crash railway suicide behaviour can be identified, using German Federal Police officers experience with suicidal events in railway related environments. METHODS: To collect ...

This study examined whether practice with arithmetic problems presented in a nontraditional problem format improves understanding of mathematical equivalence. Children (M age = 8;0; N = 90) were randomly assigned to practice addition in one of three conditions: (a) traditional, in which problems were presented in the traditional "operations on left side" format (e.g., ...

This article compares the claims of rule- and constraint-based accounts of three seemingly distinct error patterns, namely, Deaffrication, Consonant Harmony and Assibilation, in the sound system of a child with a phonological delay. It is argued that these error patterns are not separate problems, but rather are symptoms of a ...

Continuing expansion of the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) pandemic has been recognized as an exceptional challenge to global health. Taking highly active antiretroviral treatment (HAART), a confirmed effective treatment, has its limitations. While a much cheaper and potential treatment-the Chinese medicine (CM) has not been paid enough ...

Abstract Background: A centralized electrocardiogram telemetry monitoring system (TMS) facilitates early identification of critical arrhythmias and acute medical decompensation. Timely intervention can only be performed if abnormalities are communicated rapidly to the direct caregiver. The study objectives were to measure effectiveness of bi-directional voice communication badges versus one-way alphanumeric pagers ...

The effects of communal motivation on reactions to relationship partners' expressed anger were examined. In Study 1, married couples reported on the communal strength of their marriage, their expressions of anger to their spouse, and relationship satisfaction. In Study 2, college students reported on the communal strength of their best ...

We consider statistics of the disruption and Lyapunov times in an hierarchical restricted three-body problem. We show that at the edge of disruption the orbital periods and the size of the orbit of the escaping body exhibit Lévy flights. Due to them, the time decay of the survival probability is ...

We argue that Kant's views about consciousness, the mind-body problem and the status of psychology as a science all differ drastically from the way in which these topics are conjoined in present debates about the prominent idea of a science of consciousness. Kant never used the concept of consciousness in ...

When times get tough, and your organization faces an economic crisis that leads to serious cash-flow problems, keep in mind this important maxim: View lenders as partners, not adversaries.

It has been reported that the CCR5-Delta32, CCR2-64I and SDF1-3'A polymorphisms have protective effects against HIV-1 infection and can delay the progression of AIDS in European populations. The aim of this study was to investigate the associations of the three loci with HIV-1 infection and the progression of AIDS in ...

A significant number of earlier (1929-1987) and more recent (1991-2009) history of psychology textbooks have reported on the 1917 founding of the Journal of Applied Psychology (JAP). Although only G. Stanley Hall (1844-1924) was mentioned as the founder, the JAP had three financial founders: Hall, John Wallace Baird (1869-1919), and ...

Abstract Even in this so-called era of the brain, there has been no consensual agreement on understanding the genesis of the mind by the brain, the problem that also baffled Freud, the neurologist at the start of his great discoveries. Especially, there has been no progress in solving what is ...

Integration of prosthetic limb awareness into body schema is likely to aid manual control of the prosthesis. Physiotherapists and prosthetists use techniques to generate mechanical, visual and/or auditory feedback related to stimulation of the stump and proximal residual limb to improve prosthetic limb awareness. Electrical stimulation of afferent nerves using ...

The ground is shifting under the traditional approaches to problems in the philosophy of mind. Earlier doctrines concerning the independence of cognition from the brain now appear untenable. As neuroscience uncovers more about the organization and dynamics of the brain, it becomes increasingly evident that theories about our nature must ...

To investigate the striping phenomenon in fresh, enhanced pork, a series of experiments were undertaken to identify possible causes of the problem. No one factor (individual brine components, brine pH, ingredient concentration, enhancement pressure, meat and brine pH, or enhancement level) was specifically identified, which could be used to reduce ...

The Maximum Parsimony (MP) problem aims at reconstructing a phylogenetic tree from DNA sequences while minimizing the number of genetic transformations. To solve this NP-complete problem, heuristic methods have been developed, often based on local search. In this article, we focus on the influence of the neighborhood relations. After analyzing ...

Neurophilosophy embraces the hypothesis that what we call "the mind" is in fact a level of brain activity. A corollary of this hypothesis states that we can learn much about the reality of mental function by studying the brain at all levels of organization. Until fairly recently, many philosophers preferred ...

The body-mind problem invites scientific study, since mental events are repeated and repeatable and invite testable explanations. They seemed troublesome because of the classical theory of substance that failed to solve its own central problems. These are soluble with the aid of the theory of the laws of nature, particularly ...

Theories of communication often assume that communication has a single, essential form or telos, the culmination of a one-track developmental process where precursors eventually give rise to the real thing. At one time, this essence of communication was identified with linguistic competence, whereas now it is largely defined in terms ...

There is little agreement regarding best practices for constructing and assessing the quality of crosscultural measures. This paper discusses several topics that are relevant to further progress in this area: 1) a lack of consensus regarding conceptualizations of equivalence; 2) emphasis on shared methods versus shared meaning; and 3) the ...

BACKGROUND: Survivors of disaster with pre-disaster psychological problems are believed to be at risk for presenting post-disaster psychological and physical morbidity. Up till now this statement is based on cross-sectional studies with self-reported data and without pre-disaster measurement. OBJECTIVE: To monitor post-disaster health care utilization and morbidity presented in general ...

Freud's metapsychological assumption, splitting mind from brain, created two major and unsolved problems: the relation of the mind with the brain and with outer reality. Recently neuroscientists have focused on the first problem, often basing their work on a category error (mereological fallacy). The second problem may be avoided by ...

The tsunami catastrophe of December 2004 left more than 200,000 dead. Disaster victim identification (DVI) teams were presented with the unprecedented challenge of identifying thousands of mostly markedly putrefied and partially skeletised bodies. To this end, an adequate body tagging method is essential. Conventional body bag tagging in terms of ...

Foreign body ingestion is a common problem encountered in the pediatric age group. The swallowed object is often passed with little or no morbidity. Problems ensue if the ingested foreign body is hazardous, is multiple, or becomes impacted. We describe an ileal perforation following the ingestion of an alkaline disc ...

We show that the motion of a single hole in the infinite-U Hubbard model with frustrated hopping leads to weak metallic antiferromagnetism of kinetic origin. An intimate relationship is demonstrated between the simplest versions of this problem in one and two dimensions, and two of the most subtle many body ...

The four-body problem for an interacting two-species Fermi gas is solved analytically in a confined quasi-one-dimensional geometry, where the two-body atom-atom scattering length a(aa) displays a confinement-induced resonance. We compute the dimer-dimer scattering length a(dd) and show that this quantity completely determines the many-body solution of the associated BEC-BCS crossover ...

Two arguments with attempts to unify psychology are adumbrated in this commentary. First, the unification of psychology is largely a disciplinary maneuver and not primarily an epistemological act. Second, the discipline of psychology has been unified for some time around a series of methodological and functional categories that have served ...

Elliptic coordinates within the hyperspherical formalism for three-body problems were proposed some time ago [V. Aquilanti, S. Cavalli, and G. Grossi, J. Chem. Phys. 85, 1362 (1986)] and recently have also found application, for example, in chemical reaction theory [see O. I. Tolstikhin and H. Nakamura, J. Chem. Phys. 108, ...

Whether opiates and other drugs of abuse affect AIDS progression has been an unresolved issue for two decades. Credible evidence has suggested that opiates may exacerbate, retard or have 'no effect' on progression of AIDS. Differences may exist in AIDS-progression outcomes after opiate exposures that relate to neural versus, strictly, ...

The twin problems facing nineteenth-century American "mental and moral philosophy" of the nature of psychological language and the constraints that religious beliefs placed on possibilities of innovation in a "scientific Psychology" are both highly visible in the work of Noah Porter, who was unable to resolve them. They are also ...

At the end of the last century international terrorist groups declared war on the United States. Rather than pursue this war using conventional means, terrorist tactics have been employed. Terrorism represents psychological warfare, not traditional military combat. Threats of assassination, bioterrorism, and even nuclear detonations have been used. Numerous attacks ...

Statistical properties of quantum quasidegeneracy in a Calogero-like three-body problem is presented. The hidden continuous symmetry of a Calogero problem is broken by adding a three-body interaction, which results in discrete symmetry. This symmetry is sufficient to get the Shnirelman peak in level spacing statistics. Our calculation immediately implicates the ...

In a survey carried out on 229 subjects who had undergone an augmentative mammaplasty it was possible to verify a postoperative increase in weight in 25 cases, four of which were clearly anorexic. We hypothesized that a change in perception of one's body proportions after the insertion of implants, might ...

OBJECTIVE: To conceptualize the essence of the mind-body or mind-brain problem as one of metaphysics rather than science, and to propose a formulation of the problem in the context of current scientific knowledge and its limitations. METHOD AND RESULTS: The background and conceptual parameters of the mind-body problem are delineated, ...

We studied 21 former top-class competitive javelin throwers to investigate radiological and clinical symptoms in the lumbar spine many years after the end of their athletic careers. The athletes underwent clinical and radiological examinations at an average of 20 years after retiring from athletics. The Hannover questionnaire was used to ...

If an RNA-only world preceded more complex forms of life, then it is essential that the process whereby the first nucleotides were made be considered. Presumably there were no enzymes and no templates to facilitate the synthesis of the first nucleotides so another form of chemical evolution must have been ...

Many anaesthetic problems and hazards exist in children with inhaled foreign bodies. Careful, stepwise and detailed consideration of clinical history, examination and investigations cannot be over-emphasised. Special consideration has to be given to the fragile paediatric cardiopulmonary status especially in the presence of airway foreign body. The small paediatric airway ...

The year 2000 prompts numerous prognostications of the events to occur during the next century. Except for the Y2K problem, the year 2000 is little different in substance than 1999 or 2001. However it is useful to use the occasion to consider where we have come from and where we ...

The present report is a diagnostic exercise of a case of progressive anemia in a pigtail macaque with AIDS. In summary, the immune suppression of the macaque by the KUSHIV-1B virus prevented an effective immune response to simian parvovirus (SPV), resulting in persistent infection with progressive anemia. Simian parvovirus should ...

This paper reviews contemporary trends in the stability testing of pharmaceutical products. In particular, it considers the progress toward globalization and harmonization and indicates stability problems, which probably will be the focus of attention for pharmaceutical scientists and regulators in the near future. Attention is specifically directed to monitoring stability ...

We outline reasoning that led to the current theory of quasars and look at George Contopoulos's place in the long history of the N-body problem. Following Newton we find new exactly soluble N-body problems with multibody forces and give a strange eternally pulsating system that in its other degrees of ...

This study examined the relationship between patterns of progression of cocaine use and psychosocial functioning in a sample of cocaine-dependent men who were veterans. Four patterns of progression were examined: mild-severe, moderate-severe, mild-moderate-severe, and severe only. Analysis of variance and post hoc analysis with Duncan grouping revealed significant differences among ...

Non-carious, pathological loss of tooth tissue is an increasing problem for the dental profession and the effect of voluntary regurgitation practised by patients with psychological problems is well documented. However, this article describes a patient who repeatedly regurgitated, not because of psychological problems, but to control his body weight as ...

The Ab-dependent cell-mediated cytotoxicity (ADCC) activity of anti-gp120 Abs in serum from four groups of HIV-1-positive individuals in the Multicenter AIDS Cohort Study was evaluated at several time points over a 10-yr period. HIV-1-positive individuals who progressed to AIDS within 3 yr of seroconversion (rapid progressors) were compared with seroconverters ...

Golf is rapidly becoming the sport of all ages. Some play it a few times in a season; others play it every day. It is a game enjoyed by both amateurs and professionals. Golf is played socially as well as for millions of dollars in prize money. Some play with ...
