TL;DR: The power of ENU mutagenesis combined with the ability to clone murine genes by map position provides a generally applicable approach to study complex behavior in mammals.
Abstract: In a search for genes that regulate circadian rhythms in mammals, the progeny of mice treated with N-ethyl-N-nitrosourea (ENU) were screened for circadian clock mutations. A semidominant mutation, Clock, that lengthens circadian period and abolishes persistence of rhythmicity was identified. Clock segregated as a single gene that mapped to the midportion of mouse chromosome 5, a region syntenic to human chromosome 4. The power of ENU mutagenesis combined with the ability to clone murine genes by map position provides a generally applicable approach to study complex behavior in mammals.

TL;DR: The definition of epistemological beliefs takes on different shades of meaning from study to study; but, in general, researchers of personal epistemology are interested in what individuals believe about the source, certainty, and organization of knowledge, as well as the control and the speed of learning.
Abstract: The definition of epistemological beliefs takes on different shades of meaning from study to study; but, in general, researchers of personal epistemology are interested in what individuals believe about the source, certainty, and organization of knowledge, as well as the control and the speed of learning. Epistemological beliefs have been found to relate to reading comprehension, learning in complex and ill-structured domains, as well as learners' active participation and persistence in learning. Researchers are at odds on the issues of epistemological development and the roles that education and culture play in epistemological beliefs.

TL;DR: In this article, two contact force models are presented, both Hertzian in nature and based upon the direct-central impact of two solid particles, for predicting the impact response of a multibody system based on the assumption that the impacting bodies undergo local deformations and the contact forces are continuous.
Abstract: One method for predicting the impact response of a multibody system is based on the assumption that the impacting bodies undergo local deformations and the contact forces are continuous. In a continuous analysis, the integration of the system equations of motion is carried out during the period of contact; therefore, a model for evaluating the contact forces is required. In this paper, two such contact force models are presented, both Hertzian in nature and based upon the direct-central impact of two solid particles.

TL;DR: In this paper, the authors explored the relationship between time and the intention-behaviour (I-B) correlation in Fishbein and Ajzen's intention-behavior models and explored self-reported behaviours, how intention is measured, and type of behaviour as moderators to this relationship.
Abstract: Intention-behaviour models specify as a boundary condition that the intention-behaviour relationship should be measured over a short period of delay. However, a measure of intention that exists just prior to performance of the behaviour has limited feasibility and practical utility. Using meta-analysis, the present study explores the relationship between time and the intention-behaviour (I-B) correlation in Fishbein and Ajzen's intention-behaviour models. Self-reported behaviours, how intention is measured, and type of behaviour are explored as moderators to this relationship. The average I-B correlation coefficient remains strong over a prediction interval of as long as 15 years. The I-B correlation is significantly influenced by the use of self-report measures of behaviour over time and type of behaviour; however, it is not influenced by how intention is measured.

TL;DR: In this paper, the authors introduce an emerging theory of individuals' beliefs about the nature of knowledge and learning, or epistemological beliefs. But the development of these beliefs may be due to cultural, familial, and educational influences.
Abstract: This chapter introduces an emerging theory of individuals’ beliefs about the nature of knowledge and learning, or epistemological beliefs. It reviews research that tests aspects of this theory and highlights the critical role of epistemological beliefs in learning. An important issue to address is the development and modification of epistemological beliefs. Whether children are born with an “epistemological scheme” is unclear. In 1984 at the presidential address for the annual meeting of the American Educational Research Association, Richard C. Anderson stated that: It stands to reason that beliefs about knowledge that a child develops will be influenced by those of his parents. Alan Schoenfeld has suggested those students’ beliefs about quick and easy mathematical solutions and failure to integrate mathematical concepts may be a product of how they are taught. The development of these beliefs may be due to cultural, familial, and educational influences. Whether epistemological beliefs are domain-specific or not depends on the developmental level of the individual.

TL;DR: This paper found that children from single-father and single-mother families perform roughly the same in school, but both are outperformed by children from two-parent families, however, the intervening processes explaining school performance for children from Single-Father and Single-Mother families are somewhat different.
Abstract: Very little is known about the academic performance of children from single-father families. How do they achieve in school relative to children from single-mother and two-parent families? Do the same processes posited to explain the school performance of children from single-mother households account for the educational performance of children in single-father homes? These questions are addressed using a nationally representative sample of 8th graders from the National Longitudinal Study of 1988. Eight different educational outcomes are compared for 409 children in single-father, 3,483 in single-mother, and 14,269 children in biological two-parent families. Children from single-father and single-mother families perform roughly the same in school, but both are outperformed by children from two-parent families. The intervening processes explaining school performance for children from single-father and single-mother families are somewhat different, however.

TL;DR: The data do not suggest that fluoxetine improves the signs and symptoms of fibromyalgia, and both AIMS Anxiety and Depression scores and Beck Depression Scales showed improvement.
Abstract: 42 women were randomized to receive either placebo or fluoxetine at 20 mgs per day Inter and intra group differences in clinical variables were evaluated after 3 and 6 weeks of treatment Except for self rated anxiety which improved in the placebo treated group at 3 weeks, no differences between groups were riotedFor those receiving fluoxetine both AIMS Anxiety (40 baseline vs 33, p = 004) and Depression scores (26 baseline vs 19, p = 003) improved at 3 weeks; however, improvement in the Beck Depression Scale did not reach significance (118 vs 94, p = 034) At 6 weeks, both AIMS Depression (26 at baseline and 15 at 6 weeks, p = 003) and Beck Depression Scales (118 at baseline vs 83 at 6 weeks, p = 004) showed improvement, as did sleep quality (96 vs 76, p = 003) But no other variable had a significant change from baseline at either the 3 or 6 week point Our data do not suggest that fluoxetine improves the signs and symptoms of fibromyalgia

TL;DR: The hard-limiter role in the presence of thermal and APD noise and the effects of avalanche photodiode noise and thermal noise as well as interference for the OOCDMA direct-detection receiver are examined.
Abstract: In an optical multiple-access system, overall system throughput efficiency add significant implementation cost-reduction would be achieved if many users could access a common optical channel at any time without control among users. Recently one such scheme, an optical orthogonal code division multiple-access system (OOCDMA), was introduced by Salehi et al. (1982) for the case of no noise. In this paper, some extensions of that work are presented, including the effects of avalanche photodiode (APD) noise and thermal noise as well as interference for the OOCDMA direct-detection receiver. Since it has been shown that an optical hard-limiter before the receiver correlator can reduce the interference effect for the OOCDMA system in the absence of noise, the hard-limiter role in the presence of thermal and APD noise is also examined. >

TL;DR: In this paper, the authors test a social interactional model of physical aggression and find that aggression has its roots in socialization settings that are characterized by high densities of aversive stimuli and that provide frequent reinforcement for escalation to high intensity aversive behavior during social conflict.
Abstract: The objective of this study was to test a social interactional model of physical aggression. Specifically, this model hypothesizes that the performance of physical aggression has its roots in socialization settings that are characterized by high densities of aversive stimuli and that provide frequent reinforcement for escalation to high intensity aversive behavior during social conflict. Social conflicts were observed during 10 hr of interaction of each of 20 mothers and their 5-year-old sons; half of the sons were selected based on evidence of frequent aggression in home and school settings. Simple descriptive and sequential analyses indicated that aggressive relative to nonaggressive dyad members were more likely to engage in conflict, engaged in longer conflicts, were more likely to escalate to higher levels of aversiveness, and were less likely to de-escalate the intensity of conflict. In aggressive and nonaggressive dyads, the cessation of conflict contingent on the escalation of one dyad member was reliably associated with an increased likelihood of escalation and with escalation to higher levels of aversiveness by that member in the subsequent conflict. However, escalation occurred more frequently and was more likely to result in cessation of conflicts in aggressive than nonaggressive dyads.

TL;DR: Gifted and non-gifted students' beliefs about the nature of knowledge were compared in an epistemological questionnaire that assesses students' belief in fixed ability to learn, simple knowledge, quick learning, and certain knowledge as mentioned in this paper.
Abstract: Gifted and non‐gifted students' beliefs about the nature of knowledge were compared. An epistemological questionnaire that assesses students' beliefs in fixed ability to learn, simple knowledge, quick learning, and certain knowledge was administered to 1165 high school students. From this subject pool, one sample of gifted students and three samples of non‐gifted students were randomly selected. Three comparisons, between gifted and non‐gifted, were made for each epistemological factor using a 2 (Ability) X 2 (School Level) ANCOVA with gender as covariate. At the beginning of high school there appears to be no difference in students' epistemological beliefs. By the end of high school gifted students were less likely to believe in simple knowledge and quick learning. Non‐gifted students' beliefs in simple knowledge and quick learning remained stable. Gender differences were also significant. Boys were more likely to believe in fixed ability and quick learning.

TL;DR: In this article, a two-stage estimation procedure was proposed that uses an ad hoc but very easily implemented isotonization of a kernel estimator, which yields an isotonic estimator with the convergence properties of the kernel estimators.
Abstract: This article presents a two-stage estimation procedure that uses an ad hoc but very easily implemented isotonization of a kernel estimator. This procedure yields an isotonic estimator with the convergence properties of the kernel estimator. Although the isotonization in the second stage does not satisfy the least squares condition, this hybrid estimator may be considered to be a multidimensional generalization of similar procedures for the one-dimensional case suggested by Friedman and Tibshirani and by Mukarjee. We derive some of the asymptotic properties of our estimator and demonstrate other statistical properties with Monte Carlo studies. We conclude by providing a real data example.

TL;DR: In this paper, a multi-dimensional impact and process evaluation framework was used to explore the DARE (Drug Abuse Resistance Education) program in terms of long-term effects, political potency, and implementation issues.
Abstract: This article utilizes a multi-dimensional impact and process evaluation framework to explore the DARE (Drug Abuse Resistance Education) program in terms of long-term effects, political potency, and implementation issues. The impact dimension compares questionnaire data from 288 high school seniors exposed to DARE as seventh graders with 335 non-exposed seniors. No significant differences in drug use behaviors or attitudes were found between the two groups. Micro-level process findings from a focus group interview reinforced the quantitative results. At the macro-level, DARE is shown to be a form of symbolic politics, supported by direct and indirect stakeholders, and embedded in a complex and potent organizational support structure. To minimize conflicts with DARE stakeholders and enhance program understanding, we consider how factors associated with the implementation process may have influenced the results. These include contextual factors, disjunctions between program ideals and implementation realities, and program design limitations. This multidimensional evaluation approach provides both context and meaning for understanding the DARE program and for interpreting the results. It also underscores the need for a more multi-faceted discourse on drug prevention programs in order to consider the relative merits of both psychosocial and structural approaches to the issue of drug use.

TL;DR: Findings suggest that males and females are comparable on their knowledge and attitudes about sexuality in ageing and most are sexually active.
Abstract: Two studies using separate samples sought to explore differences among male and female elders on their knowledge, attitudes, and sexual behaviour using a nonexperimental approach. Two different samples from separate health and wellness groups were surveyed using the Aging Sexual Knowledge and Attitude Scale (White 1982). Additional data were collected on sexual satisfaction, sexual activity, and demographic variables. In the first study, questionnaires were mailed to the homes of 759 members of the wellness group. The second study was conducted in a similar manner, but with random selection of 400 males and 400 females. Both groups showed a moderate amount of knowledge and permissive attitudes with no significant differences observed between males and females. Reported sexual satisfaction was variable. Subjects were sexually active with activity varying from 0 to 30 times per month, with a mean of 4 times per month. Findings suggest that males and females are comparable on their knowledge and attitudes about sexuality in ageing and most are sexually active. Many are seeking further information on the impact of chronic illness and medications on sexuality.

TL;DR: It is proposed that lymphoid nodules in the distal large bowel play a promotional role following initiation of colon carcinogenesis and that ACF have little if any malignant potential in the mouse.
Abstract: Six-week-old male CF-1 mice were fed the AIN-76 diet, given eight weekly s.c. injections of either the colon carcinogen 1,2-dimethylhydrazine or saline, and killed 24 weeks after the last injection. Parameters measured in the large bowel included the incidence and locations of all intestine (gut)-associated lymphoid tissue (GALT) sites; the locations, incidence, and sizes of all aberrant crypt foci (ACF); and the incidence, locations, and types of all overt tumors. In saline-treated mice the distribution of GALT along the length of the large bowel was bimodal, with a majority peak of lymphoid nodules occurring in the distal large bowel and a minority peak occurring in the proximal large bowel. No ACF or tumors were present in the large bowel of the saline-treated mice. In 1,2-dimethylhydrazine-treated mice the majority of ACF were present in the middle third of the colon, between the two peaks of GALT, but the majority of the tumors were found over the GALT in the distal colon. There was a significant positive linear regression relationship between the numerical distribution of GALT and the numerical distribution of tumors along the length of the large bowel. There was no significant relationship between the distribution of ACF and the distribution of (a) tumors or (b) GALT along the length of the large bowel. Thus the numerical density of lymphoid nodules, not the numbers or distribution of ACF, was the significant predictor of the distribution of tumors in the large bowel of 1,2-dimethylhydrazine-treated mice. It is proposed that lymphoid nodules in the distal large bowel play a promotional role following initiation of colon carcinogenesis and that ACF have little if any malignant potential in the mouse.

TL;DR: In this article, the authors examined the effect of chlorhexidine irrigation on the periodontal status of patients with HA-coated dental implants as measured by clinical, microbiological, and immunological measures.
Abstract: The purpose of this study was to examine the effect of chlorhexidine irrigation on the periodontal status of patients with HA-coated dental implants as measured by clinical, microbiological, and immunological measures. Thirty non-adjacent implants were randomly assigned to receive a one-time irrigation with either 0.12% chlorhexidine or sterile saline, or no irrigation. All parameters were measured at baseline, 2, 5, and 8 weeks. Results showed no significant differences between any treatment modalities at any time interval. A statistically significant decrease in probing depth (P < .05) occurred within the chlorhexidine and no-treatment groups at all time intervals compared to baseline.

TL;DR: A panel session on photovoltaics applications at the 1993 International Joint Power Generation Conference (JPGC '93) held in Kansas City, Missouri, USA was organized by the IEEE Energy Development and Power Generation Committee as discussed by the authors.
Abstract: Photovoltaic (PV) systems are still in the evolutionary phase and are expected to grow for several decades to come. Fueled by environmental considerations, interest in PV is showing a healthy rise both in the minds of the public and in the planning realms of the electric power community. In recognition of this, the Energy Development Subcommittee of the IEEE Energy Development and Power Generation Committee organized a Panel Session on photovoltaics applications at the 1993 International Joint Power Generation Conference (JPGC '93) held in Kansas City, Missouri, USA. Summaries of the four presentations are assembled here for the benefit of the readers of IEEE Power Engineering Review.

TL;DR: A system that can transmit multibits per sequence-period is introduced, and avalanche photodiode (APD) noise, thermal noise, and interference, are included and improvement from using a hard-limiter is significant in the log/sub 2/F bits/sequence-period OCCDMA system.
Abstract: For part I see ibid. vol.42, no.7, p.2470 (1994). In a recently proposed optical orthogonal code division multiple-access (OOCDMA) system, one bit of user's data is transmitted per sequence-period, and a threshold is employed for the final bit decision. In this paper, a system that can transmit multibits per sequence-period is introduced, and avalanche photodiode (APD) noise, thermal noise, and interference, are included. This system, derived by exploiting orthogonal properties of the OOCDMA code sequence and using a maximum search (instead of a threshold) in the final decision, is log/sub 2/ F times higher in throughput, where F is sequence-period. For example, four orders of magnitude are better in bit error probability at -56 dBW received laser power, with F=1000 chips, 10 "marks" in a sequence, and 10 users of 30 Mb/s data rate for one-bit/sequence-period and 270 Mb/s data rate for multibits/sequence-period system. Furthermore, an exact analysis is performed for the log/sub 2/F bits/sequence-period system with a hard-limiter placed before the receiver, and its performance is compared to the performance without hard-limiter, for the chip-synchronous case. The improvement from using a hard-limiter is significant in the log/sub 2/F bits/sequence-period OCCDMA system (while it is not in a one-bit/sequence-period OOCDMA system proposed in Part I). >

TL;DR: It is shown that substituents on the rings of the polymer backbone lead to decreased conductivity, decreased Pauli susceptibility, and an increased number of Curie spins.
Abstract: Electrical conductivity, magnetic susceptibility, and electron-spin-resonance studies are reported in polyaniline and its derivatives poly(o-toluidine), poly(o-ethylaniline), and poly(o-propylaniline). It is shown that substituents on the ${\mathrm{C}}_{6}$ rings of the polymer backbone lead to decreased conductivity, decreased Pauli susceptibility, and an increased number of Curie spins. Also reflecting these features are electron-spin-resonance line shapes, which transform from Lorentzian for polyaniline toward Gaussian for poly(o-propylaniline). These results are interpreted in terms of increased electron localization caused by increased interchain disorder. Furthermore, evidence of electron-electron correlations is presented for poly(o-propylaniline).

TL;DR: In this article, the effect of lower body positive pressure (LBPP) on the cardiovascular/exercise capacities of individuals with spinal cord injury (SCI) during both arm crank exercise (ACE) and wheelchair exercise performed on a treadmill (WCTM).
Abstract: The purpose of this study was to determine the effect lower body positive pressure (LBPP) has on the cardiovascular/exercise capacities of individuals with spinal cord injury (SCI) during both arm crank exercise (ACE) and wheelchair exercise performed on a treadmill (WCTM). Ten male adults (age = 31.1 +/- 10 yr) with SCI and five male nondisabled (ND) adults (31.2 +/- 10 yr) participated in this study. The ND subjects performed ACE only. For subjects with SCI, significantly higher (P < 0.025) peak VO2 (1042 +/- 212 vs 839 +/- 218 ml.min-1), peak VE (46 +/- 17 vs 35 +/- 9 l.min-1), and work rate (50 +/- 15 vs 40 +/- 13 W) were seen during ACE with LBPP. No significant differences for peak VO2, VE, or work rate were seen for the ND subjects with LBPP during ACE. In addition, significantly higher peak VO2 (960 +/- 322 vs 828 +/- 312 ml.min-1) was recorded with LBPP for the subjects with SCI during WCTM. Cardiac output (Q, l.min-1; CO2 rebreathing method) was measured at 50% peak VO2 for both ND subjects and subjects with SCI during ACE. Subjects with SCI demonstrated significantly higher SV (94 +/- 20 vs 84 +/- 20 ml) with LBPP. No differences were observed in SV at 50% peak VO2 during ACE for the ND subjects with LBPP. The results of this study suggest that for individuals with SCI, LBPP augments exercise capacity by preventing the redistribution of blood to the lower extremities.

TL;DR: The Time Index+ overcomes the deficiencies of the Time Index by proposing an efficient new storage model for partitioning logical buckets and by suggesting a graceful new method for handling object versions with long and very long time intervals.
Abstract: 1 Introduction In this paper, we propose a new indexing structure, called the Time Index+, which extends the incremental structure techuique introduced in the Time Index [E1WK90, Kour94]. The Time Index performs well for data that often overlaps and has a non– uniform distribution. However, it requires huge amounts of storage aud suffers from degradation in update p erformauce. The Time Index+ overcomes the deficiencies of the Time Index by proposing au efficient new storage model for partitioning logical buckets and by suggesting a graceful new method for handling object versions with long and very long time intervals. We validate our claims for the efficiency of our new tectilques by analyzing and comparing four indexing structures: the Time Index+, the Time Index, the Packed R-Tree [RoLe85, KaFa93], and the Parametrized R–Tree. Our experiments identify impor-taut parameters, and show how they affect the performance of the four considered indexing structures. These include meau of version lifespan, block size, query time intervaf length, aud total number of versions. Our simulation results show that: (1) The Time Index+ pre vides au improvement in searck time of 10~o over the Time Index, of au order of magnitude over the Packed R–Tree, and of at least 100~0 over the Parametrized R–Tree and (2) The Time Iudex+ requires on average 60~0 less storage than the the Time Index but 51)~o more storage than the Packed R–Tree and the Parametrized R–Tree.

TL;DR: In this article, a Hopfield neural network architecture is developed to solve the optimal control problem for homing missile guidance, which is formulated in the form of an efficient parallel computing device known as Hopfield Neural Network.
Abstract: A Hopfield neural network architecture is developed to solve the optimal control problem for homing missile guidance. A linear quadratic optimal control problem is formulated in the form of an efficient parallel computing device known as a Hopfield neural network. Convergence of the Hopfield network is analyzed from a theoretical perspective, showing that the network, as a dynamical system approaches a unique fixed point which is the solution to the optimal control problem at any instant during the missile pursuit. Several target-intercept scenarios are provided to demonstrate the use of the recurrent feedback neural net formulation. >

TL;DR: Investigating the pain‐light season/dark season hypothesis in 2523 rheumatic disease outpatients found no clinically significant difference in pain severity between season, but a slight trend toward increased pain severity in lighter months by about 3% compared to darker months was identified.
Abstract: The clinical and neurochemical association between depression and season noted in seasonal affective disorder (SAD) has suggested that clinical pain might also be linked to season, perhaps through similar neurochemistry or the known association of depression with pain. We investigated the pain-light season/dark season hypothesis in 2523 rheumatic disease outpatients by examining VAS Pain and VAS Global Severity scores, as well as levels of depression and functional disability. No clinically significant difference in pain severity between season (or individual month) was noted for the consecutive outpatients at their first clinic visit, nor in sub-analyses using paired light and dark season visits. A slight trend toward increased pain severity in lighter months by about 3% compared to darker months was identified. No effect of season was seen on depression scores. In a subset of patients with high depression scores, rheumatoid arthritis and osteoarthritis patients, respectively, reported 16% and 7% greater pain scores in light compared to dark months, but fibromyalgia patients had stable scores. Season does not appear to play an important role in pain and/ or depression in rheumatic disorders.

Abstract: Passive augmentation techniques such as surface disruptions are being increasingly used in heat exchangers. Although many working correlations have been suggested to predict their thermal-hydraulic characteristics, the physical phenomena governing the heat transfer enhancement have not been clearly understood. The paper describes a qualitative study on the flow phenomena near an enchanced surface. Water was used as the working fluid. Experiments were conducted for different coil wire diameters and Reynolds numbers
