Environment structure and adaptive behavior from the ground up

We describe a framework for exploring the evolution of adaptive behaviors in response to different physical environment structures. We focus here on the evolving behavior-generating mechanisms of individual creatures, and briefly mention some approaches to characterizing different environments in which various behaviors may prove adaptive. The environments are described initially as simple two-dimensional grids containing food arranged in some layout. The creatures in these worlds can have evolved sensors, internal states, and actions and action-triggering conditions. By allowing all three of these components to evolve, rather than prespecifying any of them, we can explore a wide range of behavior types, including “blind” and memoryless behaviors. Our system is simple and well-defined enough to allow complete specification of the range of possible actiontypes (including moving, eating, and reproducing) and their effects on the energy levels of the creature and the environment (the bioenergetics of the world). Useful and meaningful ways of characterizing the structures of environments in which different behaviors will emerge remain to be developed.
Effective keyword search in relational databases

With the amount of available text data in relational databases growing rapidly, the need for ordinary users to search such information is dramatically increasing. Even though the major RDBMSs have provided full-text search capabilities, they still require users to have knowledge of the database schemas and use a structured query language to search information. This search model is complicated for most ordinary users. Inspired by the big success of information retrieval (IR) style keyword search on the web, keyword search in relational databases has recently emerged as a new research topic. The differences between text databases and relational databases result in three new challenges: (1) Answers needed by users are not limited to individual tuples, but results assembled from joining tuples from multiple tables are used to form answers in the form of tuple trees. (2) A single score for each answer (i.e. a tuple tree) is needed to estimate its relevance to a given query. These scores are used to rank the most relevant answers as high as possible. (3) Relational databases have much richer structures than text databases. Existing IR strategies to rank relational outputs are not adequate. In this paper, we propose a novel IR ranking strategy for effective keyword search. We are the first that conducts comprehensive experiments on search effectiveness using a real world database and a set of keyword queries collected by a major search company. Experimental results show that our strategy is significantly better than existing strategies. Our approach can be used both at the application level and be incorporated into a RDBMS to support keyword-based search in relational databases.
Measuring Memory Span

This study, conducted on a sample of 403 adult subjects, set out to explore the relationships between measures of digit span (forward and reversed), motor and spatial span, and their dependence on a broad range of measures of cognitive function. The results revealed that measures of digit span are closely related, as are measures of motor and spatial span, but these pairs of memory span measures are relatively independent of each other. Furthermore, reverse digit span, motor span, and spatial span appear to rely on what might be regarded as intellectual or executive cognitive functions. As such, the results provide little support for accounts of serial recall, which suggest that order and/or item information are more adequately modelled in a modality-independent form. Cette etude explore les relations entre des mesures d'empan de chiffre (avant et inverse), d'empan moteur et spatial, et leur relation, avec un ensemble de mesures de fonctions cognitives. Les resultats revelent que les mesures d'empan de ch.
Vigilantism during democratic transition

This article deals with vigilantism occurring in regimes undergoing transitions from non-democracy to democracy. It analyses the strategic use of vigilantism, aiming to identify the basic vigilantist strategies. The article identifies five strategies ranging from prevention initiatives organised by citizens to the outsourcing of vigilantism to informal security agencies. The extreme right also employs vigilantism to its own specific ends.
Incidence of cancer among commercial airline pilots

OBJECTIVES To describe the cancer pattern in a cohort of commercial pilots by follow up through the Icelandic Cancer Registry. METHODS This is a retrospective cohort study of 458 pilots with emphasis on subcohort working for an airline operating on international routes. A computerised file of the cohort was record linked to the Cancer Registry by making use of personal identification numbers. Expected numbers of cancer cases were calculated on the basis of number of person-years and incidences of cancer at specific sites for men provided by the Cancer Registry. Numbers of separate analyses were made according to different exposure variables. RESULTS The standardised incidence ratio (SIR) for all cancers was 0.97 (95% confidence interval (95% CI) 0.62 to 1.46) in the total cohort and 1.16 (95% CI 0.70 to 1.81) among those operating on international routes. The SIR for malignant melanoma of the skin was 10.20, 95% CI 3.29 to 23.81 in the total cohort and 15.63, 95% CI 5.04 to 36.46 in the restricted cohort. Analyses according to number of block-hours and radiation dose showed that malignant melanomas were found in the subgroups with highest exposure estimates, the SIRs were 13.04 and 28.57 respectively. The SIR was 25.00 for malignant melanoma among those who had been flying over five time zones. CONCLUSIONS The study shows a high occurrence of malignant melanoma among pilots. It is open to discussion what role exposure of cosmic radiation, numbers of block-hours flown, or lifestyle factors—such as possible excessive sunbathing—play in the aetiology of cancer among pilots. This calls for further and more powerful studies. The excess of malignant melanoma among those flying over five time zones suggests that the importance of disturbance of the circadian rhythm should be taken into consideration in future studies.
Threading through Macrocycles Enhances the Performance of Carbon Nanotubes as Polymer Fillers

In this work, we study the reinforcement of polymers by mechanically interlocked derivatives of single-walled carbon nanotubes (SWNTs). We compare the mechanical properties of fibers made of polymers and of composites with pristine SWNTs, mechanically interlocked derivatives of SWNTs (MINTs), and the corresponding supramolecular models. Improvements of both Young’s modulus and tensile strength of up to 200% were observed for the polystyrene–MINT samples with an optimized loading of just 0.01 wt %, while the supramolecular models with identical chemical composition and loading showed negligible or even detrimental influence. This behavior is found for three different types of SWNTs and two types of macrocycles. Molecular dynamics simulations show that the polymer adopts an elongated conformation parallel to the SWNT when interacting with MINT fillers, irrespective of the macrocycle chemical nature, whereas a more globular structure is taken upon facing with either pristine SWNTs or supramolecular models. The MINT composite architecture thus leads to a more efficient exploitation of the axial properties of the SWNTs and of the polymer chain at the interface, in agreement with experimental results. Our findings demonstrate that the mechanical bond imparts distinctive advantageous properties to SWNT derivatives as polymer fillers.
The Forgotten Serine

Previous work in the β2-adrenergic receptor demonstrated critical interactions between Ser-204 and Ser-207 in the fifth membrane-spanning segment and the meta-OH and para-OH, respectively, of catecholamine agonists (Strader, C. D., Candelore, M. R., Hill, W. S., Sigal, I. S., and Dixon, R. A. (1989) J. Biol. Chem. 264, 13572–13578). Using the substituted cysteine accessibility method in the β2-adrenergic receptor, we have found that in addition to Ser-204 and Ser-207, Ser-203 is also accessible on the surface of the binding-site crevice and is occluded by bound agonist. Mutation of Ser-203 to Ala, Val, or Cys reduced the binding affinity and adenylyl cyclase-activating potency of agonists containing ameta-OH, whereas their affinities and potencies were largely preserved by mutation of Ser-203 to Thr, which maintained an OH at this position. Thus both Ser-203 and Ser-204 appear to interact with the meta-OH of catecholamines, perhaps through a bifurcated H bond. Furthermore, the removal of the OH at position 203 led to a significant loss of affinity of antagonists with nitrogen in their heterocyclic ring structure. The greatest effect was seen with pindolol, a partial agonist, suggesting that a H bond between the heterocyclic ring and Ser-203 may play a role in partial agonism. In contrast, the affinities of antagonists such as propranolol or alprenolol, which have cyclic structures without H-bonding capability, were unaltered after mutation of Ser-203.
Timetable of Psychological and Behavioural Autonomy Expectations among Parents from Israel and the Former Soviet Union

The impact of culture on parental expectations for child development has been the focus of extensive investigation since the early 1980s. The present study examined the relationship between culture and parental timetables among a sample of 73 Israeli-born parents and 74 immigrant parents from the former Soviet Union. The participants responded to 57 questions related to behavioural and psychological aspects of autonomy. The results portray the conflicting expectations faced by immigrant children at home and in the host culture. Moreover, the paper provides new insights into aspects of behavioural and psychological autonomy and offers methods for their operationalization. Depuis le debut des annees 1980, de nombreuses recherches ont analyse l'impact de l'origine culturelle sur les attentes des parents envers le developpement de leur enfant. Cette etude examine la relation entre l'origine culturelle et le calendrier developpemental des parents dans un echantillon de 73 parents nes en Israel et 74 parents im.
Toward a Neuropsychology of Personality in Sex Offenders Against Children: An Exploratory Psychometric Study

Little is known about the relationship between neuropsychological functioning and normal personality in sex offenders. The aim of this study was to examine the relations between personality traits and executive functioning in child molesters. The NEO-Five Factor Inventory was used to assess personality, and the Trail Making Test (parts A and B) was used to assess executive functioning in a sample of child molesters (n = 33). We found the time required to complete Trail Making Test part A significantly predicted Extraversion scores, whereas the time to complete Trail Making Test part B significantly predicted Openness scores. Brief measures of executive functioning can thus predict the score in Extraversion and Openness in child molesters. These personality traits may be related to the functioning of brain areas implicated in having to complete the Trail Making Test.
Why Do Men and Women Challenge Gender Discrimination in the Workplace? The Role of Group Status and In‐group Identification in Predicting Pathways to Collective Action

Group status and group identification were hypothesized to moderate the predictors of collective action to challenge gender discrimination against women. Higher identifiers were expected to respond to the inequality through the lens of their in-group's interests. Among highly identified women, collective action was predicted by appraisals of illegitimacy and feelings of anger, suggesting that they felt a sense of solidarity with the victims and experienced the justice violation as personally relevant. In contrast, higher identification with the high-status group should reflect more investment in the advantaged in-group, relative to the interests of the victimized out-group members. Thus, among highly identified men, collective action intentions were predicted by perceiving the inequality as pervasive (i.e., not limited to a few cases) and feelings of sympathy for victims. This suggests that highly identified men did not experience the inequality as self-relevant until they saw it as too widespread to be ignored. In contrast, men and women with lower gender group identification demonstrated more similar pathways to collective action, where sympathy was the main predictor. Theoretical and practical implications are discussed.
Endothelial-like cells from the bovine placental cotyledon

SummaryA cell-line was established from bovine placental cotyledon. When cultured in M199 with 10% fetal bovine serum, this cell-line had a doubling time of about 18 h. With immunohistochemistry, it was demonstrated that this cell-line expressed vimentin and angiotensin-converting enzyme (ACE). While both molecules are expressed in endothelial cells, ACE is usually considered to be a specific marker for endothelial cells. Furthermore, cells were shown to take up Dil-Ac-LDL (acetylated low-density lipoprotein labeled with 1,1′-dioctadecyl-3,3,3′-tetramethylindo-carbocyanine perchlorate). This characteristic feature has been used to identify endothelial cells. Finally, when cultured on matrigel, this cell-line formed tube-like structures similar to those formed by endothelial cells. Tube-formation on matrigel is a physiological property specific to endothelial cells. In conclusion, these three lines of evidence strongly suggest that this cell-line is endothelial cell in nature. Further studies using an endothelial cell-line from bovine placenta may help to elucidate the cause of bovine placental retention, a major cause for economic loss in bovine industry. Furthermore, an endothelial cell-line could be an important tool in research areas such as tissue remodeling, angiogenesis, and cancer.
Advertising Professionals’ Perceptions of the Impact of Gender Portrayals on Men and Women: A Question of Ethics?

This research investigates advertising professionals’ perceptions of how gender portrayals impact men and women and how these perceptions influence their strategic and creative choices. Two rounds of qualitative data were collected to examine these issues. Findings reveal professionals’ perceptions about women's vulnerability and men's immunity to the negative consequences of advertising, as well as the societal discourses and institutional dynamics that drive their business decisions. The authors detail four themes with regard to professionals’ conceptualizations of the influence of gender portrayals on consumers and the ethical considerations surrounding such images. Theoretical and managerial implications and consumer welfare ramifications are offered.
Restoration of instantaneous amplitude and phase using Kalman filter for speech enhancement

This paper proposes a restoration scheme for the instantaneous amplitudes and phases in sub-bands by using a Kalman filter with linear prediction (LP). A few important studies have already proved that phase spectrum on the short term Fourier transform plays an important role in speech enhancement. Thus, the proposed scheme concentrates on restoring of both the instantaneous amplitudes and phases simultaneously. In this scheme, the Kalman filter is used for both instantaneous amplitudes and phases in the sub-band representation to remove the effect of noise. Thus, it can sufficiently reduce the noise effects in both. Simulations were carried out in various noisy environments to evaluate the effectiveness of the proposed scheme. The signal to error ratio (SER), perceptual evaluation of speech quality (PESQ), and SNR loss were used as objective measures. Results showed that the proposed scheme can effectively improve these objective measures more than conventional methods.
Brane - Antibrane as a Defect of Tachyon Condensation

In a tachyon effective field theory of a non-BPS brane, we construct a classical solution representing a parallel brane-antibrane. The solution is made of a kink and an antikink placed at antipodal points of S1. Estimation of the brane energy suggests an excitation of a string connecting the two branes, even though the theory is abelian. We performed fluctuation analysis around the obtained solution, and find the structure of the supersymmetry breaking by the co-existence of the brane and the antibrane. We discuss possible processes of the pair-annihilation of the brane defect.
Athletes' trust, mental skills, and satisfaction in a gambling-legal cycle racing business in South Korea

Abstract The purpose of this study was to examine the differences of athletes' trust, mental skills associated with athletic performance, and satisfaction in a gambling-legal cycle racing business. A multivariate analysis of variance, using 328 professional racing cyclists in South Korea, showed older athletes (over 40 years old) rated cognition-based trust the highest. The shorter career athletes (1–3 years) rated affect-based trust and mental skills the highest, while a longer career (over 7 years) and the highest class of racing cyclists rated cognitive skills the lowest. The results also suggested that younger athletes (20–29 years old) have higher levels of social satisfaction than older athletes. In addition, athletes with shorter careers rated social and task satisfaction the highest. Finally, we found that longer career athletes had the lowest levels of trust, mental skills, and athlete satisfaction. The results may assist administrators to better understand the important issues of managing athletes in the unique cycle racing business.
Role of subvoxel free fluid on diffusion parameters in brain tissue with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy and its correlation with physical disability: histogram analysis of standard and fluid-attenuated MR diffusion.

BACKGROUND AND PURPOSE Subcortical signal intensity abnormalities and lacunar infarcts are the radiologic hallmark of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. MR diffusion studies reveal abnormalities in lesions and also within normal appearing white matter. To further characterize the underlying pathologic abnormality, we evaluated the role of subvoxel free fluid in brain with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy on diffusion parameters and physical disability and analyzed the interrelation between diffusion variables and nonlacunar T2 lesion load. METHODS Mean diffusivity maps from fluid-attenuated and standard diffusion images of 13 patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy and seven age-matched control participants were compared by means of histogram analysis for three tissue compartments (whole brain parenchyma, normal appearing brain tissue, and nonlacunar lesions) by using a semiautomated region growing algorithm to define whole brain parenchyma and lesions on fluid-attenuated images. RESULTS In both patients and control participants, the average mean diffusivity of whole brain parenchyma was lower on fluid-attenuated than on standard images (P <.001). Average mean diffusivity and peak location for all compartments were significantly elevated in patients (P <.001) and higher for lesions than for normal appearing brain tissue on both types of images (P <.001). The difference between standard and fluid-attenuated average mean diffusivity of normal appearing brain tissue, reflecting the subvoxel free fluid content, was elevated in patients (P <.05) and correlated closely with the Rankin score (Spearman's rank correlation coefficient = 0.889, P <.001). Average mean diffusivity of whole brain parenchyma and normal appearing brain tissue correlated strongly with the nonlacunar T2 lesion load (Pearson's correlation coefficient = 0.743-0.928, P <.005). CONCLUSION This study shows that standard diffusion measurements are contaminated by free fluid partial volume effects for patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy and for control participants. It also provides evidence of a clinical significance of increased subvoxel free fluid in normal appearing brain with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, which may be more important than either global atrophy, increased diffusivity or, T2 lesion load.
Emergent walking stop using 3-D ZMP modification criteria map for humanoid robot

Real-time emergent stop walking motion is necessary for humanoid robots. We propose a new emergent stop method using modification criteria map. The stable gait change is generated by adjusting the amount of the ZMP modification according to the timing of stop command. The modified ZMP trajectory is given so that the humanoid robot can change the current motion without falling down. The modification criteria are defined from the relation between the predicted ZMP trajectory using a preview controller and the support polygon. The preview controller employs table-cart model and it derives center of mass (CoM) trajectory from ZMP reference in real-time. We make the map of relation among the ZMP modification length, the modification timing and the timing of the stop command for stable gait modification. The robot can execute the best motion referring to the predefined map. In this method, the humanoid robot can stop immediately within one step or zero step to avoid a collision, if humans or objects appeared unexpectedly in front of the walking humanoid robot. The stop motion is typically divided two phase: single leg support phase and double leg support phase. In the single leg support phase, the next landing position and timing are decided according to command time of the stop signal. In the double leg support phase, the humanoid robot can stop anytime without changing standing position. The validity of the proposed method is confirmed by experiment using a humanoid robot HRP-2.
Rat CINC/gro: a novel mediator for locomotive and secretagogue activation of neutrophils in vivo

The effects of rat CINC/gro, a member of the interleukin‐8 family, on the endothelium‐neutrophil interaction and transendothelial macromolecular leakage were studied in rat mesenteric microcirculation. Thirty minutes after superfusion with 10 nM CINC/gro, the number of neutrophils adherent to the venular endothelium and those migrated across the venules were significantly increased with a concomitant elevation of luminol‐dependent chemiluminescence at the site of adhesion. Transendothelial macromolecular leakage as assessed by the relative length of venular wall stained with monastral blue B was also increased at 30 min after the start of CINC/gro superfusion. Pretreatments with a CD18‐directed monoclonal antibody, WT‐3 (1 mg/kg), significantly attenuated the increase in number of adherent and migrated neutrophils, the increase in luminol‐dependent chemiluminescence, and the venular macromolecular leakage after the application of CINC/gro. These data suggest that CINC/gro is a novel stimulator that evokes not only locomotive but also secretagogue activation of neutrophils via a CD18‐dependent mechanism in viva J. Leukoc. Biol. 55: 652–657; 1994.
