Old, slowly cooled apatites often yield overdispersed helium ages due to factors such as parent zonation, He implantation, radiation damage, crystal defects, and fluid inclusions. Careful mineral selection and many replicate analyses can mitigate the impact of some of these effects. However, this approach adds unnecessary costs in time and resources when dating well-behaved apatites and is generally ineffective at identifying the root cause of age dispersion and providing suitable age corrections for poorly behaved samples. We assess a new technique utilizing static-gas measurement during continuous heating as a means to rapidly screen apatite samples. In about the time required for a conventional total-gas analysis, this method can discriminate between samples showing the volume-diffusion behavior expected for apatite and those showing anomalous release patterns, inconsistent with their use in thermochronologic applications. This method may also have the potential to quantify and discriminate between the radiogenic and extraneous 4He fractions released by a sample. Continuously heated samples that outgas by volume diffusion during a linear heating schedule should produce a characteristic sigmoidal 4He fractional loss profile, with the exact shape and position of these profiles (in loss vs. heating time space) controlled by sample kinetics, grain size, and heating rate. Secondary factors such as sample zoning and alpha-loss distribution have a relatively minor impact on such profiles. Well-behaved examples such as the Durango standard and other apatites with good age reproducibility show the expected smooth, sigmoidal gas release with complete exhaustion by temperatures predicted for volume diffusion using typical apatite kinetics (e.g., by ~900˚C for linear heating at 20˚C/minute). In contrast, "bad actor" samples that do not replicate well show significant degrees of helium release deferred to higher temperatures. We report on screening results for a range of

Experience sampling methods are essential tools for building a modern idiographic approach to understanding personality. These methods yield multiple snapshots of people’s experiences over time in daily life and allow researchers to identify patterns of behavior within a given individual, rather than strictly identify patterns of behavior across individuals, as with standard nomothetic approaches. In this article, we discuss the origin and evolution of idiographic methods in the field of pers...

The inert gases helium, neon, argon, krypton, and xenon were measured mass-spectrometrically in the metal phases of fifteen iron meteorites and in graphite and troilite mineral separates from the Odessa iron meteorite. The meteorites analyzed were chosen because of their low cosmic ray exposure ages; most had known exposure ages of less than 200 million years. The hope was that the prominent spallation component seen in prior iron meteorite inert gas measurements would be reduced enough to allow detection of a trapped gas component, should one exist. Approximately three gram samples were fused in a thoroughly outgassed alumina crucible. Surface contamination was removed from the samples by acid treatment and by preheating the samples for two days at 3000C. Blank measurements were made for correction purposes before and after each sample. All of the meteorite samples show evidence of having a cosmogenic inert gas component. Small variations attributable to different trace element abundances and cosmic ray shielding are seen. Large deviations from the predicted cosmogenic compositions correlate with short cosmic ray exposure ages and often indicate the presence of a trapped atmospheric-like inert gas component. Those samples showing anomalous behavior in one inert gas tend to show anomalous behavior for all the inert gases. The inert gas data from most samples are consistent with the helium, neon, and argon concentrations being largely of cosmogenic origin and the krypton and xenon resulting from a mix of solar wind, atmospheric, and cosmogenic compositions. However, there are several meteorites which are anomalous with respect to the above interpretation

Full Text Available This work describes the usability studies conducted in the development of an experience-sampling methodology (ESM system running in a mobile device. The goal of the system is to improve the accuracy and ecology in gathering daily self-report data in individuals suffering a chronic pain condition, fibromyalgia. The usability studies showed that the developed software to conduct ESM with mobile devices (smartphones, cell phones can be successfully used by individuals with fibromyalgia of different ages and with low level of expertise in the use of information and communication technologies. 100% of users completed the tasks successfully, although some have completely illiterate. Also there seems to be a clear difference in the way of interaction obtained in the two studies carried out.

The temperamental trait of negative emotionality (NE) plays an important role in maladaptation among adults experiencing significant life stress. However, the prospective relation between childhood NE and subsequent interrelated behavioral, emotional, and biological dysregulation in later life has not yet been established among children who experience early adversity. Using a longitudinal sample of youth who experienced parental divorce during childhood (N = 160; 53% male; 83% White), we tested the hypothesis that childhood NE would predict physiological, emotional, and behavioral dysregulation 15 years later. NE was assessed by maternal report when youth were between 9 and 12 years old. Fifteen years later, young adults (mean age = 25.55 years) participated in a psychosocial stress task to assess cortisol reactivity and reported on internalizing symptoms and problematic alcohol use. Structural equation modeling revealed that higher childhood NE predicted significantly greater alcohol use, internalizing symptoms, and total cortisol output during a stress task 15 years later. Importantly, these findings held after adjusting for childhood internalizing symptoms. In addition, problematic alcohol use was associated with greater cortisol reactivity and internalizing symptoms. Findings suggest that childhood NE is a critical risk marker for interrelated forms of dysregulation in young adulthood among at-risk youth. (PsycINFO Database Record PMID:27100364

With intensively collected longitudinal data, recent advances in the experience-sampling method (ESM) benefit social science empirical research, but also pose important methodological challenges. As traditional statistical models are not generally well equipped to analyze a system of variables that contain feedback loops, this paper proposes the utility of an extended hidden Markov model to model reciprocal the relationship between momentary emotion and eating behavior. This paper revisited an ESM data set (Lu, Huet, & Dube, 2011) that observed 160 participants' food consumption and momentary emotions 6 times per day in 10 days. Focusing on the analyses on feedback loop between mood and meal-healthiness decision, the proposed reciprocal Markov model (RMM) can accommodate both hidden ("general" emotional states: positive vs. negative state) and observed states (meal: healthier, same or less healthy than usual) without presuming independence between observations and smooth trajectories of mood or behavior changes. The results of RMM analyses illustrated the reciprocal chains of meal consumption and mood as well as the effect of contextual factors that moderate the interrelationship between eating and emotion. A simulation experiment that generated data consistent with the empirical study further demonstrated that the procedure is promising in terms of recovering the parameters. PMID:26717120

Objective: To summarize the CT and MRI features in a series of fifteen cases of Kimura's disease. Materials and methods: The clinical data, CT and MRI findings of 15 patients with histologically proved Kimura's disease were retrospectively reviewed. All imaging data were consensually evaluated by two radiologists to determine the lesion location, number, morphology, margin, signal intensity or CT density, lesion texture, contrast enhancement pattern and involvement of adjacent structures. Results: There were 14 male and 1 female, with peripheral blood eosinophilia in all 14 patients. 13 patients were presented with a painless mass. 13 patients had lesions located in the head and neck related to the major salivary glands. 1 patient had lesion in groin. Subcutaneous fat diffuse atrophy around the tumor site was found in 11 patients. 9 patients had solitary mass and 6 patients had multiple masses. Most masses were ill-defined, but no specific density or signal patterns were found. Most patients exhibited enlarged or obviously enhanced abnormal lymph nodes but without necrosis. Conclusion: The characteristic distribution, morphology with enlarged draining lymphadenopathy, combined with the clinical features and laboratory examination enables a confident preoperative diagnosis of Kimura's disease.

Fifteen years ago, on 25 August 1997, NASA launched the Advanced Composition Explorer (ACE) spacecraft. In operation for more than a solar cycle, ACE has provided numerous important scientific results while at the same time becoming a key component of the space weather-monitoring system and a cornerstone of the fleet of distributed spacecraft that make up the Heliophysics Great Observatory. ACE is located on the sunward side of Earth about 1.5 million kilometers away, or 4 times as far from Earth as is the Moon. This puts ACE well outside the Earth's magnetosphere and in an ideal position to monitor the solar wind environment “upwind” of Earth. ACE has six high-resolution spectrometers that measure the elemental, isotopic, and ionic charge-state composition of ions from hydrogen to iron; it also includes three particle and field monitors. One of the nine instruments has now failed (Solar Energetic Particle Ionic Charge Analyzer (SEPICA)), and two others are partially degraded (Solar Wind Ion Composition Spectrometer (SWICS) and Solar Wind Electron, Proton, and Alpha Monitor (SWEPAM)); however, the other six are working well. Instrument descriptions are available on the ACE Web site at http://www.srl.caltech.edu/ACE/.

New deep optical and near-infrared imaging is combined with archival ultraviolet and infrared data for fifteen nearby galaxies mapped in the Spitzer Extended Disk Galaxy Exploration Science survey. These images are particularly deep and thus excellent for studying the low surface brightness outskirts of these disk-dominated galaxies with stellar masses ranging between 10^8 and 10^11 Msun. The spectral energy distributions derived from this dataset are modeled to investigate the radial variations in the galaxy colors and star formation histories. Taken as a whole, the sample shows bluer and younger stars for larger radii until reversing near the optical radius, whereafter the trend is for redder and older stars for larger galacto-centric distances. These results are consistent with an inside-out disk formation scenario coupled with an old stellar outer disk population formed through radial migration and/or the cumulative history of minor mergers and accretions of satellite dwarf galaxies. However, these trends...

A fifteen-year forecast of the electric requirements of the in-province customers of New Brunswick Power Commission is prepared each year based on a cause and effect analysis of past loads, combined with data gathered through customer surveys and an assessment of economic, demographic, technological and other factors which affect the utilization of electrical energy. In addition to the forecast requirements of each sales classification and total energy supply by month, a forecast of the monthly peak hour demand is also presented. The forecast results are used in overall short and long term planning, particularly the financial and facilities planning. Since variations from the forecast can significantly affect the future financial and facilities requirements, a forecast range is included which indicates the sensitivity of the forecast to various input parameters and their resulting impact on the final results. Total power demand is forecast to increase from 13,183 GWh to 19,703 GWh or 2.8%/y over the 15-year period; in the same period, the maximum peak demand is forecast to increase from 2637 MW to 3818 MW. These results are generally the same as in the previous year's forecast. Nevertheless, the latest forecast shows a trend toward lower energy consumption, a phenomenon which responds to the short term economic situation. By end-use sector, power demand is forecast to grow from 4316 GWh to 6240 GWh in the residential sector, from 2169 GWh to 3454 GWh in the general sector, and from 5247 GWh to 8319 GWh in the industrial sector. 15 figs., 18 tabs

Inner speech is often reported to be a common and central part of inner experience, but its true prevalence is unclear. Many questionnaire-based measures appear to lack convergent validity and it has been claimed that they overestimate inner speech in comparison to experience sampling methods (which involve collecting data at random timepoints). The present study compared self-reporting of inner speech collected via a general questionnaire and experience sampling, using data from a custom-made smartphone app (Inner Life). Fifty-one university students completed a generalized self-report measure of inner speech (the Varieties of Inner Speech Questionnaire, VISQ) and responded to at least seven random alerts to report on incidences of inner speech over a 2-week period. Correlations and pairwise comparisons were used to compare generalized endorsements and randomly sampled scores for each VISQ subscale. Significant correlations were observed between general and randomly sampled measures for only two of the four VISQ subscales, and endorsements of inner speech with evaluative or motivational characteristics did not correlate at all across different measures. Endorsement of inner speech items was significantly lower for random sampling compared to generalized self-report, for all VISQ subscales. Exploratory analysis indicated that specific inner speech characteristics were also related to anxiety and future-oriented thinking. PMID:25964773

This study examined relations between passage of time judgments and duration judgments (DJs) in everyday life, in young and elderly people, with an Experience Sampling Method. The DJs were assessed by verbal estimation and interval production measures. The results showed no difference between young and elderly people in judgments of rate of passage of time, a result contrary to the conventional idea that time passes more quickly as we get older. There were also no significant relation between the judgment of passage of time and the judgments of durations. In addition, the significant predictors of individual differences in the judgment of passage of time (emotion states and focus of attention on the current activity) were not predictors of judgment of durations. In sum, passages of time judgments are not related to DJs. PMID:26925006

The Experience Sampling Method was used to explore emotions to music as they naturally occurred in everyday life, with a focus on the prevalence of different musical emotions and how such emotions are related to various factors in the listener, the music, and the situation. Thirty-two college students, 20 to 31 years old, carried a palmtop that emitted a sound signal seven times per day at random intervals for 2 weeks. When signaled, participants were required to complete a questionnaire on the palmtop. Results showed that music occurred in 37% of the episodes, and in 64% of the music episodes, the participants reported that the music affected how they felt. Comparisons showed that happiness-elation and nostalgia-longing were more frequent in episodes with musical emotions, whereas anger-irritation, boredom-indifference, and anxiety-fear were more frequent in episodes with nonmusical emotions. The prevalence of specific musical emotions correlated with personality measures and also varied depending on the situation (e.g., current activity, other people present), thus highlighting the need to use representative samples of situations to obtain valid estimates of prevalence.

Full Text Available ObjectiveThe aim of this longitudinal study was to identify predictors of instantaneous well-being in patients with amyotrophic lateral sclerosis (ALS. Based on flow theory well-being was expected to be highest when perceived demands and perceived control were in balance, and that thinking about the past would be a risk factor for rumination which would in turn reduce well-being.MethodsUsing the experience sampling method, data on current activities, associated aspects of perceived demands, control, and well-being were collected from 10 patients with ALS three times a day for two weeks.ResultsResults show that perceived control was uniformly and positively associated with well-being, but that demands were only positively associated with well-being when they were perceived as controllable. Mediation analysis confirmed thinking about the past, but not thinking about the future, to be a risk factor for rumination and reduced well-being. DiscussionFindings extend our knowledge of factors contributing to well-being in ALS as not only perceived control but also perceived demands can contribute to well-being. They further show that a focus on present experiences might contribute to increased well-being.

Recent evidence suggests that emotional well-being improves from early adulthood to old age. This study used experience-sampling to examine the developmental course of emotional experience in a representative sample of adults spanning early to very late adulthood. Participants (N = 184, Wave 1; N = 191, Wave 2; N = 178, Wave 3) reported their emotional states at five randomly selected times each day for a one week period. Using a measurement burst design, the one-week sampling procedure was repeated five and then ten years later. Cross-sectional and growth curve analyses indicate that aging is associated with more positive overall emotional well-being, with greater emotional stability and with more complexity (as evidenced by greater co-occurrence of positive and negative emotions). These findings remained robust after accounting for other variables that may be related to emotional experience (personality, verbal fluency, physical health, and demographic variables). Finally, emotional experience predicted mortality; controlling for age, sex, and ethnicity, individuals who experienced relatively more positive than negative emotions in everyday life were more likely to have survived over a 13 year period. Findings are discussed in the theoretical context of socioemotional selectivity theory. PMID:20973600

Anxiety and stress are everyday issues for many people with high-functioning autism, and while cognitive-behavioural therapy is the treatment of choice for the management of anxiety, there are challenges in using it with people with high-functioning autism. This study used modified experience sampling techniques to examine everyday anxiety and stress in adults with high-functioning autism and to explore the feasibility of delivering real-time stress management techniques using a mobile platform. High levels of anxiety were found to be characterised by worry, confusing thoughts and being alone but was not associated with internal focus, imagery or rumination. Participants reported improved mood and less worry and anxious thinking in the active phase of the study. These results support previous studies indicating that people with high-functioning autism differ in their experience of anxiety and provided preliminary data on the feasibility of real-time stress management. The limitations of this approach are discussed together with considerations for future work in the area of developing clinical interventions on mobile platforms. PMID:26514793

The aim of study was to examine the effect of cannabis on affect and bipolar symptoms in a group of individuals with bipolar disorder.Twenty-four participants with bipolar disorder type I or type II completed diaries for 6 days using Experience Sampling Methodology to investigate the temporal associations between cannabis, affect and bipolar disorder symptoms.The results indicated that higher levels of positive affect increase the odds of using cannabis (OR:1.25 ,CI:1.06-1.47, P=0.008. However, neither negative affect, manic nor depressive symptoms predicted the use of cannabis. Cannabis use was associated with subsequent increases in positive affect (β=0.35, CI:0.20-0.51, P=0.000, manic symptoms (β=0.20,CI:0.05-0.34, P=0.009 and depressive symptoms (β= 0.17,CI:0.04-0.29, P=0.008.The findings indicate that cannabis use is associated with a number of subsequent psychological effects. However there was no evidence that individuals with BD were using cannabis to self-medicate minor fluctuations in negative affect or bipolar disorder symptoms over the course of daily life. The findings in relation to existing literature and clinical implications are discussed.

This study examined, within the context of the Contingencies of Self-Worth model, state-based associations between self-esteem and body satisfaction using the experience sampling method. One hundred and forty-four adolescent girls (mean age = 14.28 years) completed up to 6 assessments per day for one week using Palm Digital Assistants, in addition to baseline measures of trait body satisfaction and self-esteem. Results showed considerable variation in both state-based constructs within days, and evidence of effects of body satisfaction on self-esteem, but not vice versa. Although these state-based associations were small in size and weakened as the time lag between assessments increased for the sample as a whole, individual differences in the magnitude of these effects were observed and predicted by trait self-esteem and body satisfaction. Collectively, these findings offer support for key tenets of the Contingencies of Self-Worth model. PMID:26356806

A growing range of studies have begun to document the health and well-being benefits associated with contact with nature. Most studies rely on generalized self-reports following engagement in the natural environment. The actual in-situ experience during contact with nature, and the environmental features and factors that evoke health benefits have remained relatively unexplored. Smartphones offer a new opportunity to monitor and interact with human subjects during everyday life using techniques such as Experience Sampling Methods (ESM) that involve repeated self-reports of experiences as they occur in-situ. Additionally, embedded sensors in smartphones such as Global Positioning Systems (GPS) and accelerometers can accurately trace human activities. This paper explores how these techniques can be combined to comprehensively explore the perceived health and well-being impacts of contact with nature. Custom software was developed to passively track GPS and accelerometer data, and actively prompt subjects to complete an ESM survey at regular intervals throughout their visit to a provincial park in Ontario, Canada. The ESM survey includes nine scale questions concerning moods and emotions, followed by a series of open-ended experiential questions that subjects provide recorded audio responses to. Pilot test results are used to illustrate the nature, quantity and quality of data obtained. Participant activities were clearly evident from GPS maps, including especially walking, cycling and sedate activities. From the ESM surveys, participants reported an average of 25 words per question, taking an average of 15 s to record them. Further qualitative analysis revealed that participants were willing to provide considerable insights into their experiences and perceived health impacts. The combination of passive and interactive techniques is sure to make larger studies of this type more affordable and less burdensome in the future, further enhancing the ability to understand
While most prior research has focused on the frequency of family meals the issue of which elements of family mealtime are most salient for adolescents' well-being has remained overlooked. The current study used the experience sampling method, a unique form of time diary, and survey data drawn from the 500 Family Study (N = 237 adolescents with…

Financial professionals have a great deal of discretion concerning how to relay information about the risk of financial products to their clients. This paper introduces a new risk tool to communicate the risk of investment products, and it examines how different risk-presentation modes influence risk-taking behavior and investors' recall ability of the risk-return profile of financial products. We analyze four different ways of communicating risk: (i) numerical descriptions, (ii) experience s...
Full Text Available Although ego depletion effects have been widely observed in experiments in which participants perform consecutive self-control tasks, the process of ego depletion remains poorly understood. Using the strength model of self-control, we hypothesized that chronic ego depletion adversely affects goal adherence and that mental effort and motivation are involved in the process of ego depletion. In this study, 203 students reported their daily performance, mental effort, and motivation with respect to goal directed behavior across a 3-week time period. People with high levels of chronic ego depletion were less successful in goal adherence than those with less chronic ego depletion. Although daily effort devoted to goal adherence increased with chronic ego depletion, motivation to adhere to goals was not affected. Participants with high levels of chronic ego depletion showed a stronger positive association between mental effort and performance, but chronic ego depletion did not play a regulatory role in the effect of motivation on performance. Chronic ego depletion increased the likelihood of behavior regulation failure, suggesting that it is difficult for people in an ego-depletion state to adhere to goals. We integrate our results with the findings of previous studies and discuss possible theoretical implications.

Self-regulation is a critical ability for maintaining a wide range of health behaviors, especially in preventing overeating and weight gain. Previous work has identified various threats to self-control in the eating domain, chief among which are desire strength and negative affect. In the present study, we examined individual differences in college-aged dieters' experiences of these threats as they encountered temptations to eat in their daily lives, and tested whether these differences characterized sub-groups of dieters with divergent self-control outcomes. Specifically, 75 dieting females (age range: 18-23) participated in a combined functional magnetic resonance imaging (fMRI) and experience sampling study. Participants passively viewed food cues during a fMRI session, and then reported their daily eating behaviors for one week via ecological momentary assessment. We examined the characteristics of dieters who exhibited the most favorable combination of the aforementioned factors (i.e., low desire strength and positive mood) and who were thus most successful at regulating their eating. These dieters endorsed more autonomous reasons for their self-regulatory goals, and during the food cue reactivity task more readily recruited the inferior frontal gyrus, a brain region associated with inhibitory control. We suggest that these motivational and neural correlates may also be implicated in self-regulation of other important health behaviors. PMID:27058281

Immunization programs are important tools for reducing child mortality, and they need to be in place for each new generation. However, most national immunization programs in developing countries are financially and organizationally weak, in part because they depend heavily on funding from foreign sources. Through its Sustainable Immunization Financing Program, launched in 2007, the Sabin Vaccine Institute is working with fifteen African and Asian countries to establish stable internal funding for their immunization programs. The Sabin program advocates strengthening immunization programs through budget reforms, decentralization, and legislation. Six of the fifteen countries have increased their national immunization budgets, and nine are preparing legislation to finance immunization sustainably. Lessons from this work with immunization programs may be applicable in other countries as well as to other health programs. PMID:21653967

Full Text Available Although very rare, medullary thyroid carcinoma (MTC is the most aggressive in differentiated thyroid malignancies. We report a 48-year-old male patient with the diagnosis of MTC, who was monitored for fifteen years and showed no serious adverse events due to long-term chemotherapy. Total thyroidectomy, neck dissection, retrosternal nodule excision and pericardiectomy were performed, and radiotherapy was applied to the neck area. Due to progressive metastatic disease cyclophosphamide, dacarbazine, and vincristine were administrated. He tolerated chemotherapy well, and no severe systemic side effects were detected. He died due to multi-organ failure after fifteen years of diagnosis. The only curative treatment is surgery in MTC, however; radiotherapy, chemotherapy, and embolization may be used for patients for whom surgery cannot be performed. Although success rates of systemic chemotherapy are low, it is a treatment option in the progressive metastatic disease.

"This paper examines fifteen cases of collective action in six villages in rural Bangladesh. Collective action was defined broadly and identified from significant episodes in previous life-history research in the same villages. The types of collective action identified were catalyzed by marriage; dowry and domestic violence; disputes over land; illness, injury and death in accidents; and theft and cheating. The role of development NGOs was less significant than would be expected considering t...

A treatment method for main bronchus fistula after pneumonectomy via median sternotomy was described by P. Abruzzini in 1961. This operation is performed in an area not involved with infection. Fifteen patients underwent the procedure in our surgical department; one of them died of myocardial infarction while all the others survived for different periods of time, closely associated with the original disease; seven were long-term survivors. The transmediastinal approach seems an effective means of managing such a difficult complication. PMID:10880846

Stevia [Stevia rebuaidana (Bertoni); family: Asteraceae] is known to yield diterpenoid steviol glycosides (SGs), which are about 300 times sweeter than sugar. The present work analyzed the expression of various genes of the SGs biosynthesis pathway in different organs of the plant in relation to the SGs content. Of the various genes of the pathway, SrDXS, SrDXR, SrCPPS, SrKS, SrKO and three glucosyltransferases namely SrUGT85C2, SrUGT74G1 and SrUGT76G1 were reported from stevia. Here, we report cloning of seven additional full-length cDNA sequences namely, SrMCT, SrCMK, SrMDS, SrHDS, SrHDR, SrIDI and SrGGDPS followed by expression analysis of all the fifteen genes vis-à-vis SGs content analysis. SGs content was highest in the leaf at 3rd node position (node position with reference to the apical leaf as the first leaf) as compared to the leaves at other node positions. Except for SrDXR and SrKO, gene expression was maximum in leaf at 1st node and minimum in leaf at 5th node. The expression of SrKO was highest in leaf at 3rd node while in case of SrDXR expression showed an increase up to 3rd leaf and decrease thereafter. SGs accumulated maximum in leaf tissue followed by stem and root, and similar was the pattern of expression of all the fifteen genes. The genes responded to the modulators of the terpenopids biosynthesis. Gibberellin (GA(3)) treatment up-regulated the expression of SrMCT, SrCMK, SrMDS and SrUGT74G1, whereas methyl jasmonate and kinetin treatment down-regulated the expression of all the fifteen genes of the pathway.

An analytical method for the simultaneous determination of fifteen ultraviolet (UV) filters in sunscreen cosmetics was developed by high performance liquid chromatography (HPLC). Various cosmetic samples including lotions, emulsions, creams and waxes were firstly mixed thoroughly by adding tetrahydrofuran containing 2 g/L ammonium hydroxide followed by vortex and oscillation. If the wax samples were still homogenized incompletely, a ultrasonic oscillation protocol with heating to 50 °C was adopted. The homogeneous samples were then ultrasonically extracted by 80% aqueous methanol solution. After centrifugation and micropore filtration, the extracted components were separated on an XTerra MS C18 column with gradient elution by water containing 0. 1% (v/v) formic acid and methanol containing 0. 1% (v/v) formic acid, determined by a diode array detector (DAD) at 280 nm and 311 nm, and quantified using external standard method. Optimization for the pretreatment conditions of different matrices of cosmetics including sample dispersion solvents, extraction solvents and time were carried out. This developed method showed good linearity (r2 ≥ 0.999 1) and the limits of quantification (LOQs) were between 1.2 and 5.1 µg/g. The recoveries of the fifteen compounds ranged from 84.2% to 100.7% at three spiked levels with the relative standard deviations (RSDs) between 0.9% and 9.5%. The analytes were well separated and this analytical method proved to be sensitive and accurate, so it can be used in the practical determination of the fifteen UV filters in commercial sunscreen cosmetics.

The author proposes some analyses and comments about the relationships between experts who have been involved in various conferences and meetings (from Rio de Janeiro in 1992 to Marrakech in 2002) on climate change. He presents the different groups of experts and comments the issues which have been a matter of debate between them for the past fifteen years. For each of these issues, he gives an overview of the expertise status, highlights consensus as well as dissensus. He compares this expertise with the content of political discourses, and then shows which mechanisms led to The Hague failure and to the incomplete Marrakech's compromise

Here we review the field of atom chips in the context of Bose-Einstein Condensates (BEC) as well as cold matter in general. Twenty years after the first realization of the BEC and fifteen years after the realization of the atom chip, the latter has been found to enable extraordinary feats: from producing BECs at a rate of several per second, through the realization of matter-wave interferometry, and all the way to novel probing of surfaces and new forces. In addition, technological applications are also being intensively pursued. This review will describe these developments and more, including new ideas which have not yet been realized.

Full Text Available The increase in the concentration of the banking industry across European Union countries during the last fifteen years can be explained in terms of: a global factors, like the comprehensive adoption of technological innovations, the intensification of competition that has resulted from the deregulation of the financial sector and, more recently, as a consequence of the government interventions and forced acquisitions prompted by the 2007-2009 financial crisis; and, b factors that have been specific to the E.U., in particular, the structural changes that took place in the region as a result of the creation of the Single Financial Market (1993 and the introduction of the euro (1999. This work analyzes the concentration process of the banking industry in the E.U. during the last fifteen years giving preeminence to the strategic choices made by the region’s commercial banks. It also reports the most visible E.U. banks’ M&As and government interventions that resulted from the 2007-2009 financial crisis, make a preliminary evaluation of the outcomes, and suggests possible future trends for the banking industry in the region.

Many people accept the idea that time seems to pass more quickly as they get older, as if this is a psychological reality. However, systematic investigations of differences in judgments of passage of time between young and elderly people are very rare and contradictory. The present study examined the experience of passage of time in daily life in young and elderly people using Experience Sampling Methodology (ESM), with 8 alerts per day for 5 days being delivered by smartphones. At each alert, a short questionnaire was filled in, asking questions about passage of present time, affective state, arousal level, and attention to current activities, among others. Our ESM study found no difference between the young and the old participants in the judgment of passage of present time. Irrespective of the participants' age, the experience of passage of time in every-day life was significantly related to affective states and current activities when they captured attention.

While emotional difficulties are highly implicated in borderline personality disorder (BPD), the dynamic relationships between emotions and BPD symptoms that occur in everyday life are unknown. The current paper examined the function of negative emotions as they relate to BPD symptoms in real time. Experience sampling methodology with 281 participants measured negative emotions and borderline symptoms, expressed as a spectrum of experiences, five times daily for two weeks. Overall, having a BDP diagnosis was associated with experiencing more negative emotions. Multilevel modeling supported positive concurrent relationships between negative emotions and BPD symptoms. Lagged models showed that even after 3 hours negative emotions and several symptoms continued to influence each other. Therefore, results indicated that negative emotions and BPD symptoms are intricately related; some evidenced long-lasting relationships. This research supports emotion-symptom contingencies within BPD and provides insight regarding the reactivity and functionality of negative emotions in borderline pathology. PMID:25710731
In 2010, fifteen years after the Beijing declaration on women's rights, the UN Commission on the Status of Women met to review progress in gender mainstreaming. Reports on gender equality by member states revealed differences in the degree of change achieved in this period, while highlighting common barriers to gender mainstreaming. The same barriers have long been identified by academics and activists, but prove remarkably resistant to strategies to address gender inequalities. This paper reviews approaches to gender mainstreaming in the context of health policy, and suggests that a model of the obstacles to gender mainstreaming, which identifies barriers as essentially pragmatic, conceptual, or political in origin, might enable a more explicit discussion of the factors underlying this resistance and the ways in which they might be challenged.

Emotional exhaustion (EE) is the core component in the study of teacher burnout, with significant impact on teachers' professional lives. Yet, its relation to teachers' emotional experiences and emotional labor (EL) during instruction remains unclear. Thirty-nine German secondary teachers were surveyed about their EE (trait), and via the experience sampling method on their momentary (state; N = 794) emotional experiences (enjoyment, anxiety, anger) and momentary EL (suppression, faking). Teachers reported that in 99 and 39% of all lessons, they experienced enjoyment and anger, respectively, whereas they experienced anxiety less frequently. Teachers reported suppressing or faking their emotions during roughly a third of all lessons. Furthermore, EE was reflected in teachers' decreased experiences of enjoyment and increased experiences of anger. On an intra-individual level, all three emotions predict EL, whereas on an inter-individual level, only anger evokes EL. Explained variances in EL (within: 39%, between: 67%) stress the relevance of emotions in teaching and within the context of teacher burnout. Beyond implying the importance of reducing anger, our findings suggest the potential of enjoyment lessening EL and thereby reducing teacher burnout. PMID:25566124

Hypothesized relationships between experiential avoidance (EA), self-esteem, and paranoia were tested using structural equation modeling in a sample of student participants (N = 427). EA in everyday life was also investigated using the Experience Sampling Method in a subsample of students scoring high (N = 17) and low (N = 15) on paranoia. Results showed that paranoid students had lower self-esteem and reported higher levels of EA than nonparanoid participants. The interactive influence of EA and stress predicted negative self-esteem: EA was particularly damaging at high levels of stress. Greater EA and higher social stress independently predicted lower positive self-esteem. Low positive self-esteem predicted engagement in EA. A direct association between EA and paranoia was also found. These results suggest that similar mechanisms may underlie EA and thought suppression. Although people may employ EA to regulate self-esteem, this strategy is maladaptive as it damages self-esteem, incurs cognitive costs, and fosters paranoid thinking. PMID:19752645

Since the aliphatic C–H···anion interaction is relatively weak, anion binding using hydrophobic aliphatic C–H (Cali–H) groups has generally been considered not possible without the presence of additional binding sites that contain stronger interactions to the anion. Herein, we report X-ray structures of organic crystals that feature a chloride anion bound exclusively by hydrophobic Cali–H groups. An X-ray structure of imidazolium-based scaffolds using Cali–H···A‑ interactions (A‑ = anion) shows that a halide anion is directly interacting with fifteen Cali–H groups (involving eleven hydrogen bonds, two bidentate hydrogen-bond-type binding interactions and two weakly hydrogen-bonding-like binding interactions). Additional supporting interactions and/or other binding sites are not observed. We note that such types of complexes may not be rare since such high numbers of binding sites for an anion are also found in analogous tetraalkylammonium complexes. The Cali–H···A‑ interactions are driven by the formation of a near-spherical dipole layer shell structure around the anion. The alternating layers of electrostatic charge around the anion arise because the repulsions between weakly positively charged H atoms are reduced by the presence of the weakly negatively charged C atoms connected to H atoms.

Fifteen years has passed on this year since accident at the Chernobyl Nuclear Power Plant had formed on April 26, 1986. From before or after the accident, the world experienced a number of changes. On August, 1986, USSR carried out a report on the accident at an international conference on the accident at Chernobyl held at Wien. Outlines of the report are described in a report of IAEA INSAG (INSAG-1). After then, various facts hidden in the USSR report at this time have appeared. Then, INSAG revised previous INSAG-1 and published INSAG-7 re-evaluated on technical meanings of the accident on 1992, which became so-called finished issue on technical analysis and evaluation on causes and progresses of the accident. To correctly understand lessons on the accident, it must be begun from correct understanding of its real facts. It is widely recognized that its actual and fundamental reason was slight or neglect on safety found at whole of nuclear development and applications in USSR and shorts of safety culture such as emptiness of technology and regulation brought by them, relaxation of working rule, and so on, which were only the largest lesson on the Chernobyl accident.

Examining dental students' profiles and perspectives contributes to discussions concerning dental education and practice. This study aimed, first, to investigate Brazilian dental students' reasons for pursuing dentistry as an occupation and, secondly, to consider the professional expectations of freshman students at a Brazilian public university over a fifteen-year period. A cross-sectional study was performed using data from a self-administered questionnaire to all first-year students enrolled in the 1993-95 and 2006-08 periods at the Federal University of Goias, Brazil (n=376). A total of 296 students responded (response rate=78.7 percent). Frequency analysis and chi-square tests were used to compare frequencies between the two time periods. Job conception was cited as the primary reason for pursuing dentistry, and the students considered oral health promotion and oral disease prevention as the primary purposes of dentistry. Most students intended to serve both high and low socioeconomic populations and both private and public practices after graduation. The majority cited an interest in specializing in clinical fields, orthodontics being the most frequent option. Significant trends included a greater interest in health promotion and public services and specializing in aesthetic dentistry and implantology in the 2006-08 period. This study revealed significant differences in the freshman students' motivations and professional perspectives over time. Personal views and concepts about profession are major influencing factors for choosing dentistry as a career. PMID:21205736
The paper reports on fifteen years of teaching and research experience in nuclear physics at the University of Madagascar. Many difficulties were encountered in setting up the Laboratory of Nuclear Physics and Applied Physics (LPNPA) from scratch. At the outset there were no offices, laboratory rooms, students, technicians or research workers - and only one professor, who had done his research in theoretical (elementary particle) physics. Through the support of the Malagasy Government, in particular the Ministry of Higher Education and Scientific Research, and the assistance of the International Atomic Energy Agency beginning in 1977, these difficulties were overcome and some thirty students were successfully trained locally at post-Masters level, laboratories were set up for X-ray fluorescence analysis, alpha and gamma radioactivity studies, and equipped with solid-state nuclear detectors. All this culminated in some fifty publications. The paper also describes the recommended strategy (programme development, mushrooming, bilateral and/or multilateral co-operation problems, training of teachers, and the endogenous approach).

The five to fifteen (FTF) is a parent questionnaire developed to assess ADHD, its common comorbid conditions and associated problems in children and adolescents. The present study examined (1) the psychometric properties of scores on the new teacher version of the FTF, (2) competing models of the FTF subdomain structure and (3) the psychometric properties and utility of scores on the newly developed FTF impact questions. Parents (n=4258) and teachers (n=1298) of Danish children and adolescents (ages 5 to 17 years), selected using simple random sampling, completed the FTF. In the largest study of the FTF to date, parent and teacher scores had acceptable psychometric properties. The FTF subdomains were organized into six domains labelled cognitive skills, motor/perception, emotion/socialization/behaviour, attention, literacy skills and activity control and analysis of these domains may provide additional information when applying the FTF in the future. The impact questions yielded information above and beyond that provided by symptom count alone and appeared to increase the ability of the FTF to identify at risk children and adolescents.

Summary Background Immunocompromised patients, especially those receiving treatment with corticosteroids and cytotoxic chemotherapy are at increased risk for developing Legionella pneumonia. Objective The aim of this study was to determine clinical and radiographic characteristics of pulmonary infection due to Legionella in persons undergoing treatment for cancer and stem cell transplant (SCT) recipients. Methods Retrospective review of Legionella cases at MSKCC over a fifteen-year study period from January 1999 and December 2013. Cases were identified by review of microbiology records. Results During the study period, 40 cases of Legionella infection were identified; nine among these were due to non-pneumophila species. Most cases occurred during the summer. The majority [8/9, (89%)] of patients with non-pneumophila infection had underlying hematologic malignancy, compared to 18/31 (58%) with Legionella pneumophila infections. Radiographic findings were varied-nodular infiltrates mimicking invasive fungal infection were seen only among patients with hematologic malignancy and hematopoietic stem cell transplant (SCT) recipients and were frequently associated with non-pneumophila infections (50% vs 16%; P = 0.0594). All cases of nodular Legionella pneumonia were found incidentally or had an indolent clinical course. Conclusions Legionella should be considered in the differential diagnosis of nodular lung lesions in immunocompromised patients, especially those with hematologic malignancy and SCT recipients. Most cases of nodular disease due to Legionella are associated with non-pneumophila infections. PMID:26496794

Our empirical results show that we can predict GDP growth rate more accurately in continent with fewer large economies, compared to smaller economies like Malaysia. This difficulty is very likely positively correlated with subsidy or social security policies. The stage of economic development and level of competiveness also appears to have interactive effects on this forecast stability. These results are generally independent of the forecasting procedures. Countries with high stability in their economic growth, forecasting by model selection is better than model averaging. Overall forecast weight averaging (FWA) is a better forecasting procedure in most countries. FWA also outperforms simple model averaging (SMA) and has the same forecasting ability as Bayesian model averaging (BMA) in almost all countries.

A novel gold immunochromatographic assay (GICA) based on anti-β-lactam receptors was innovatively developed that successfully allowed rapid and simultaneous detection of fifteen β-lactams in milk samples in 5-10 minutes. By replacing the antibodies used in traditional GICA with anti-β-lactam receptors, the difficulty in producing broad specific antibodies against β-lactams was overcome. Conjugates of ampicillin with BSA and goat anti-mouse immunoglobulin (IgG) were immobilized onto the test and control lines on the nitrocellulose membrane, respectively. Since goat anti-mouse IgG does not combine with receptors, negative serum from mice labelled with gold nanoparticles (GNP) was mixed with GNP-labelled receptors. Results were obtained within 20 min using a paper-based sensor. The utility of the assay was confirmed by the analysis of milk samples. The limits of detection (LOD) for amoxicillin, ampicillin, penicillin G, penicillin V, cloxacillin, dicloxacillin, nafcillin, oxacillin, cefaclor, ceftezole, cefotaxime, ceftiofur, cefoperazone, cefathiamidine, and cefepime were 0.25, 0.5, 0.5, 0.5, 1, 5, 5, 10, 25, 10, 100, 10, 5, 5, and 2 ng mL-1, respectively, which satisfies the maximum residue limits (MRL) set by the European Union (EU). In conclusion, our newly developed GICA-based anti-β-lactam receptor assay provides a rapid and effective method for one-site detection of multiple β-lactams in milk samples.A novel gold immunochromatographic assay (GICA) based on anti-β-lactam receptors was innovatively developed that successfully allowed rapid and simultaneous detection of fifteen β-lactams in milk samples in 5-10 minutes.

Full Text Available The aim of a two-year study was to characterise selected Allium cepa L. genotypes with regard to their ability to accumulate nitrates in bulbs as well as to search for a possible relation between NO3- concentration and dry matter content. Fifteen cultivars of edible onion, mostly of long-day genotype with different growing periods, bulb size and skin colour, were taken for the experiment. Seeds of particular cultivars were obtained from the following seed companies: Spójnia Nochowo (‘Labrador’, ‘Takstar F1’,‘Tęcza’, ‘Warna’, ‘Zorza’, Polan (‘Polanowska’, ‘Topolska’, PlantiCo Gołębiew (‘Alibaba’, ‘Efekt’, ‘Kristine’, ‘Niagara F1’,and PlantiCo Zielonki (‘Bila’, ‘Irka’, ‘Wenta’, ‘Zeta’. Plants produced from seedlings were grown in the experimental field of the University of Agriculture in Kraków. After crop harvesting and additional drying, nitrate and dry matter content in bulbs of all cultivars were measured. The following cultivars: ‘Efekt’, ‘Labrador’ and red-skinned ‘Wenta’, were characterized by the lowest ability to accumulate NO3- in bulbs. The highest nitrate content was noted in bulbs of ‘Takstar F1’ (a very early-season cultivar, followed by ‘Bila’ and ‘Tęcza’. A weak, yet statistically significant negative correlation between nitrate and dry matter content was observed. The highest dry matter content was determined in bulbs of white-skinned ‘Alibaba’, while the lowest – in brown-skinned ‘Labrador’.
Full Text Available In this article, Professor Vickrey shows that current economic policy is based on incomplete analyses, counterfactual assumptions, and false analogies. The article examines in detail fifteen fallacies which, taken together, lead to policies which at best generate economic lethargy with unemployment rates close to 5 or 6 percent. For Professor Vickrey, this situation is harmful in that it reduces potential production between 10 and 15 percent even if the loss is distributed in an equitable way among the population; but when it turns into unemployment of 10, 20, and up to 40 percent for the less favored groups, the additional harm in terms of poverty, family breakup, school absence and dropout, illegitimacy,
drug use, and crime becomes very serious. Thus these policies are like a 'premeditated homicidal fire' and, even worse, when they are carried to their ultimate consequences, in search of 'budgetary equilibrium', they can lead to a deep depression.En este articulo, el profesor Vickrey muestra que la politica economica actual se basa en analisis incompletos, supuestos contrafactuales y analogias falsas.

Para el profesor Vickrey, esta situacion es perjudicial por cuanto reduce la produccion potencial entre un 10 y un 15 por ciento aun asi la perdida de se reparte de forma equitativa entre toda la poblacion; pero cuando se traduce un desempleo de 10, 20 o hasta 40 por ciento para los grupos desfavorecidos, los perjuicios adicionales en terminos de pobreza, ruptura familiar, ausencia y desercion escolar, ilegitimidad, uso de drogas y crimenes llegan a ser muy graves. De modo que estas politicas se asemejan a un "incendio homicida premeditado" y, aun peor, cuando se llevan hasta sus ultimas concecuencias, en busca de un 'presupuesto equilibrado

Full Text Available We have produced annual estimates of national and global gas flaring and gas flaring efficiency from 1994 through 2008 using low light imaging data acquired by the Defense Meteorological Satellite Program (DMSP. Gas flaring is a widely used practice for the disposal of associated gas in oil production and processing facilities where there is insufficient infrastructure for utilization of the gas (primarily methane. Improved utilization of the gas is key to reducing global carbon emissions to the atmosphere. The DMSP estimates of flared gas volume are based on a calibration developed with a pooled set of reported national gas flaring volumes and data from individual flares. Flaring efficiency was calculated as the volume of flared gas per barrel of crude oil produced. Global gas flaring has remained largely stable over the past fifteen years, in the range of 140 to 170 billion cubic meters (BCM. Global flaring efficiency was in the seven to eight cubic meters per barrel from 1994 to 2005 and declined to 5.6 m3 per barrel by 2008. The 2008 gas flaring estimate of 139 BCM represents 21% of the natural gas consumption of the USA with a potential retail market value of $68 billion. The 2008 flaring added more than 278 million metric tons of carbon dioxide equivalent (CO2e into the atmosphere. The DMSP estimated gas flaring volumes indicate that global gas flaring has declined by 19% since 2005, led by gas flaring reductions in Russia and Nigeria, the two countries with the highest gas flaring levels. The flaring efficiency of both Russia and Nigeria improved from 2005 to 2008, suggesting that the reductions in gas flaring are likely the result of either improved utilization of the gas, reinjection, or direct venting of gas into the atmosphere, although the effect of uncertainties in the satellite data cannot be ruled out. It is anticipated that the capability to estimate gas flaring volumes based on satellite data will spur improved utilization of

In an experience-sampling study that bridged laboratory, ecological, and individual-differences approaches to mind-wandering research, 72 subjects completed an executive-control task with periodic thought probes (reported by McVay & Kane, 2009) and then carried PDAs for a week that signaled them 8 times daily to report immediately whether their thoughts were off-task. Subjects who reported more mind wandering during the laboratory task endorsed more mind-wandering experiences during everyday ...
The content of fifteen elements such as Ca, Mg, Na, K, Mn, Zn, Co, Cu, Cr, Ni, Pd, Cd, Ba and Al were determined in Green Tea samples imported from different countries such as India, China, Kenya and Bangladesh in packets and without packets were purchased from authorized tea dealers in Peshawar. Wet ashing procedures were employed for decomposing the organic matter in the tea samples. Aqueous extract of each green tea sample was also prepared by heating with de-ionized water at 80 /sup o/C on electric heating plates. (author)

We derive 15 classes of time-dependent two-state models solvable in terms of the confluent Heun functions. These classes extend over all the known families of 3- and 2-parametric models solvable in terms of the Gauss hypergeometric and the Kummer confluent hypergeometric functions to more general four-parametric classes involving three-parametric detuning modulation functions. The classes suggest a variety of families of field configurations possessing useful properties not covered by the previously known analytic models. In the case of constant detuning the field configurations defined by the derived classes describe excitations of two-state quantum systems by symmetric or asymmetric pulses of controllable width and edge-steepness. The particular classes out of the derived fifteen that provide constant detuning pulses of finite area are identified and the factors controlling the corresponding pulse shapes are discussed in detail. The positions of the pulse edges for the case of step-wise edges are determined...
Some of the operational data of the reactor are presented. The great number of samples irradiated in 1970 and 1971 was due to cyclic irradiation of samples for fission experiments. The maximum of the number of pulses performed per year was reached in 1973 with 2315 pulses. In the following years the number of pulses decreased, while the energy generated and also the operating time increased. This was due to increasing steady state operation of the reactor for two mass separators, installed at two beam-tubes and also to the use of steady state operation instead of pulses for irradiations combined with fast chemical separations. Until 1980 more than 12,800 pulses have been performed. A chronological survey of the maintenance work and the improvements done at the reactor is given
This work has been constituted around four questions: the future of the Chernobyl site, the damaged reactor, and the sarcophagus around it; the health consequences of the accident on the persons that have worked on the damaged reactor and on the population in the countries the most exposed to fallout,; the situation of contaminated territories around the power plant and their management today; the last question concerns especially the France with the consequences of the radioactive cloud and what we know about the health risks induced by this event.

The report presents fifteen individual case studies of high-performing and unique local weatherization agencies. This research was one component of the retrospective evaluation of the U.S. Department of Energy s Weatherization Assistance Program. The agencies were chosen to represent a range of contexts and approaches to weatherization. For example, the set of agencies includes a mix of urban and rural agencies, those that mainly use in-house crews to weatherize homes versus those that use contractor crews, and a mix of locations, from very cold climates to moderate to hot humid and dry climates. The case studies were mainly based on site visits to the agencies that encompassed interviews with program directors, weatherization crews, and recipients of weatherization. This information was supplemented by secondary materials. The cases document the diversity of contexts and challenges faced by the agencies and how they operate on a day-by-day basis. The cases also high common themes found throughout the agencies, such as their focus on mission and respect for their clients.

Full Text Available One of the most controversial issues that the Pre-Trial Chamber I of the International Criminal Court had to decide in their judgment against Thomas Lubanga Dyilo was the legal treatment of the acts of sexual violence committed during the armed conflict of Ituri. This was a challenging aspect because the Prosecutor had previously decided not to present charges based on sex crimes. On the contrary, he mostly focused his prosecutorial strategy on the war crimes of conscripting, enlisting children under the age of fifteen years or using them to participate actively in hostilities. Facing that situation, the majority of the Trial Chamber I decided not to analyse the issue, while judge Elizabeth Odio Benito took up this point and considered that acts of sexual violence constitute an active participation in hostilities. In this essay I will critically analyse both opinions with the aim of offering an alternative explanation. The latter could be read as follows: despite the fact that acts of sexual violence were not included in the charges, they are covered by the conducts of conscripting or enlisting.
Full Text Available During the last fifteen years a notable number of labour market interventions took place in Italy, under two main headings: new regulations and implementation of active and/or passive programmes. The paper reviews a fair number of subjectively selected impact evaluation studies published in the last ten years. The framework is provided by counterfactual analysis; preliminary, its barebones are sum up. The focus of the review in on two aspects. First, a blend of empirical and analytical issues critical for credible impact evaluations are discussed. They emerge from the fact that the reviewed studies are carried out in an observational setting, and refer to prospective vs. retrospective evaluation, availability (or lack of adequate data, over-identification tests in order to corroborate (or falsify the identifying restriction on which the evaluation strategy rests, and heterogeneous effects. Second, the substantive evidence offered by the reviewed studies is summarized. It points to generally minor policy effects; some tentative explanations for that lack of effectiveness are suggested.
In a first article, the author discusses the possible content of a law on energy transition which is supposed to be voted by the Parliament during the autumn 2014, and which will probably decide the shutting down of some French nuclear plants. The author outlines the social, economical and energy-related consequences of such a policy. In a second article he rejoices over the publication of two reports (one on the Energy Climate Package by the Cour des Comptes, and one by the General Commissioner for Strategy and Prospective) which consider that the objectives of development of renewable energies (notably wind and photovoltaic) are too ambitious and even unrealistic, and outline the bad management of investments and the inefficiency of action by the ADEME and the Ministry of Ecology. In the third article he denounces fifteen 'tales' about the German energy model, the uselessness of seven German nuclear plants which have been stopped, the low cost of energy transition, the environmental benefit of renewable energies, the high potential of energy savings, the new electricity storage means, the electric car as a new mean of storage of electric current, the sun which does not send any bill, wind energy (when a wind farm is said to be able to supply energy to so many thousands households), geothermal energy production, technological leap, the benefit of decentralization, the miracle of job creation by renewable energies, the ecologic electricity, nuclear wastes we do not know what to do with
The TMI-2 accident keeps providing unique full scale data giving opportunities to check the ability of the codes to model overall plant behaviour and to perform many sensitivity and uncertainty calculations. Some countries continue improving their system codes using the TMI data. The objective of this status report was to summarise on-going activities on TMI-2 analysis in NEA member countries, and progress made in this area, and to find out to which extent current advanced codes are able to model later phases of the TMI-2 accident. The work started in early spring 2003 under the lead of IRSN (Institut de Radioprotection et de Surete Nucleaire). The participating organisations and their codes used were as follows: ENEA (Ente per le Nuove tecnologie, l'Energia e l'Ambiente, Italy): ASTEC, ICARE/CATHARE V1 and SCDAP/RELAP5; GRS (Gesellschaft fur Anlagen- und Reaktorsicherheit, Germany) : ATHLET-CD; IRSN (Institut de Radioprotection et de Surete Nucleaire, France): ICARE/CATHARE V2; NRC (Nuclear Regulatory Commission, United States of America): MELCOR; Univ. Pisa (Universita di Pisa, Italy): SCDAP/RELAP5; PSI (Paul Scherrer Institute, Switzerland): MELCOR. In this report, several experts in using severe accident codes have provided their views about the progress made during the last fifteen years in the calculation of the TMI-2 transient: physical modelling improvements (thermal hydraulics, cladding oxidation, material properties, molten corium progression, debris bed), plant and transient description improvements, comparison with last benchmark conclusions
The content of fifteen elements i.e. Ca, Mg, Na, K, Fe, Mn, Zn, Co, Cu, Cr, Ni, Pd, Cd, Ba and Al were determined for 30 sample from three types of green tea samples using flame atomic absorption spectroscopy. The samples were purchased from authentic tea dealer in Peshawar imported from India, China and Kenya. However, some samples were taken which were locally produced in Pakistan with branded packing and without package. The NBS tea leaves. The wet digestion and infusion procedure reference material was also analyzed simultaneously with tea samples. The wet digestion and infusion procedures were employed for determination of total elements and aqueous extracted elements respectively. It was found that, considerable amount of essential and trace elements are present in total in tea infusion. The levels of toxic metals are low but level of aluminum is high in both forms. The results obtained from this analysis have shown good accuracy and reproducibility. The relative error and relative standard deviation were less than 10% for most of the elements analyzed. (author)

The response styles theory of depression (Nolen-Hoeksema, 1991) proposes three main strategies individuals employ in response to low mood: rumination, active coping (distraction and problem-solving) and risk taking. Although recent research has suggested this theory has utility in understanding the symptoms of bipolar disorder (BD), the role of these processes in conferring vulnerability to the condition is poorly understood. Twenty-three adolescent children of patients with BD and 25 offspring of well parents completed the Experience Sampling Method (ESM; Csikszentmihalyi and Larson, 1987) diary for six days. Longitudinal analyses were carried out to examine inter-relationships between mood, self-esteem and response styles. Increased negative as well as positive mood resulted in greater rumination in both groups. Low self-esteem triggered greater risk-taking at the subsequent time point in the at-risk group, while negative affect instigated increased active coping in the control group. In both groups, engagement in risk-taking improved mood at the subsequent time point, whilst rumination dampened self-esteem. Differential longitudinal associations between mood, self-esteem and response styles between at-risk and control children suggest early psychological vulnerability in the offspring of BD parents, with important indications for early intervention.

Full Text Available The aim of the present paper is to describe the changes in the educationalsystem in the Czech Republic that have taken place from the beginning of the 1990’s up to the present. The first part includes a brief characterisation of the initial situation typical of the socialist model of education and a specification ofthose areas that were viewed sceptically or critically after the „velvet revolution»in 1989, and that have been identified as areas where a change is desirable. Next part of the paper describes the course of changes and reforms of education in subsequent years. Periodisation of reforms is carried out on the basisof a general model that has been created, as one of possible approaches, for postsocialist countries in transformation. Each part of the model, i.e. the correctivereforms, modernization reforms, structural reforms and system reforms, containsan outline of the respective individual changes that took place in the Czech Republic in the course of the last, almost fifteen years, and the changes arecritically evaluated.There are some documents (e.g. the Czech «White Paper» that are of essential importance to the recent and current situation in the Czech educational systembecause they create basic visions and orientation but also a strategy of future changes. The documents are treated in the next section of the present text. It isfollowed by a brief analysis of the current situation of the Czech educational system, namely as regards the educational opportunities and participation in education, structure and network of schools, financing of the Czech educational system, and finally the school leavers’ prospects at the labour market.The last part of the paper deals with the outlooks of further development of the Czech educational system in connection with the entry into the European Union,and a conclusion is drawn that it involves mutual convergence of problems caused by global economic and social forces that also leads to

Self_incompatibility (SI) is a major genetic mechanism to prevent self_fertilization in flowering plants and, in most cases, controlled by a single multiallelic locus, known as the S locus. In Brassica, the genes mediating both stylar (SRK, S receptor kinase) and pollen (SCR/SP11, S locus cystein rich protein/S locus protein 11) expression of self_incompatible reaction have been characterized though the first S locus_encoded gene, SLG (S locus glycoprotein), was isolated nearly fifteen years ago. These findings have finally unveiled the molecular partners in pollen recognition during self_incompatible reaction in Brassica.

Between October 1986 and November 1987, 208 total hip arthroplasties were performed with use of the cementless Zweymüller stem and a threaded cup in 200 consecutive patients. Of 102 patients (108 hips) who were available for follow-up at a minimum of 180 months postoperatively, eighty-three (eighty-nine hips) had the primary joint replacement still intact. No stem had been revised because of aseptic loosening, but we found various degrees of osteolysis around sixteen (18%) of the implants. The probability of survival of the stem at fifteen years was 0.98 (95% confidence interval, 0.96 to 1.00). The probability of survival of the cup was 0.85 (95% confidence interval, 0.79 to 0.91).

Although a large body of work has examined the benefits of transformational leadership, this work has predominantly focused on recipients of such behaviors. Recent research and theory, however, suggest that there are also benefits for those performing behaviors reflective of transformational leadership. Across 2 experience-sampling studies, we investigate the effects of such behaviors on actors' daily affective states. Drawing from affective events theory and self-determination theory we hypothesize and find that engaging in behaviors reflective of transformational leadership is associated with improvement in actors' daily affect, more so than engaging in behaviors reflective of transactional, consideration, initiating structure, and participative leadership. Behaviors reflective of transformational leadership improved actors' affect in part by fulfilling their daily needs. Furthermore, extraversion and neuroticism moderated these effects such that extraverts benefitted less whereas neurotics benefitted more from these behaviors in terms of affective changes. We consider the theoretical and practical implications of these findings and offer directions for future research. PMID:26348475
Purpose: To report 15-year biochemical relapse-free survival (BRFS), cause-specific survival (CSS), and overall survival (OS) outcomes of patients treated with I125 brachytherapy monotherapy for clinically localized prostate cancer early in the Seattle experience. Methods and Materials: Two hundred fifteen patients with clinically localized prostate cancer were consecutively treated from 1988 to 1992 with I125 monotherapy. They were prospectively followed as a tight cohort. They were evaluated for BRFS, CSS, and OS. Multivariate analysis was used to evaluate outcomes by pretreatment clinical prognostic factors. BRFS was analyzed by the Phoenix (nadir + 2 ng/mL) definition. CSS and OS were evaluated by chart review, death certificates, and referring physician follow-up notes. Gleason scoring was performed by general pathologists at a community hospital in Seattle. Time to biochemical failure (BF) was calculated and compared by Kaplan-Meier plots. Results: Fifteen-year BRFS for the entire cohort was 80.4%. BRFS by D'Amico risk group classification cohort analysis was 85.9%, 79.9%, and 62.2% for low, intermediate, and high-risk patients, respectively. Follow-up ranged from 3.6 to 18.4 years; median follow-up was 15.4 years for biochemically free of disease patients. Overall median follow-up was 11.7 years. The median time to BF in those who failed was 5.1 years. CSS was 84%. OS was 37.1%. Average age at time of treatment was 70 years.

This panel presentation at the Journal's conference in St Petersburg responded to the conference theme of 'Ancestors in Personal, Professional and Social History' by relating it to the experience of training and being trained on the IAAP 'router' programme in Russia. The two organizers of the programme (JW and CC) have worked in Russia for over 12 years, bringing analysts from Britain to Moscow and St Petersburg on a 'shuttle' basis as supervisors and personal analysts. A few months after handing over the router programme in December 2010 to the Russian colleagues they had trained, they invited four analysts, three Russian and one Belarusian, to tell a short personal story about their training, linking it to the theme of 'the Ancestors'. The resulting four stories are very different but complement each other, using imagery to illustrate issues concerning both value and ambivalence. JW and CC jointly wrote their story about the programme in response to the four stories, reflecting on some of their themes and from them, giving consideration to the flexibility and limits of such a model of cross-cultural training. Themes in the stories included the possibility of mutual adaptation to another culture without losing tradition and identity; moving on from doctrinaire Soviet attitudes in education to embrace 'not knowing'; both organizers and routers learning from mistakes and from joint experience without guilt or shame; the need to protect reflective space amidst the constraints of time and geography. All Russian and UK contributors could finally acknowledge their shared luck to find themselves in the right place at the right time to respond to the collective revival of psychoanalytic practice in Russia.

There are four fundamental extended objects with d > 2 world-volume dimensions and D-dimensional spacetime supersymmetry: (d = 3, D = 11), (d = 6, D = 10), (d = 4, D = 6), and (d = 3, D = 4). A simultaneous dimensional reduction of the world volume and the spacetime then yields four sequences of super-extended object which include the four classical Green-Schwarz superstrings (d = 2, D = 10, 6, 4, and 3) as special cases. We discuss which of these models is likely to be quantum consistent and finish with some speculations. (author)

In magmatic arcs the conditions of volatile exsolution exert a direct control on the composition of exsolved magmatic volatiles phases (MVPs), as well as on their parental magmas. The ability to accurately assess the exchange of major and trace elements between MVPs and magmas is key to understanding the evolution of arc magmas. The trace element signatures measured in arc volcanoes, fumaroles, and hydrothermal ore deposits are greatly influenced by the role of MVPs. In order to investigate the interplay and evolution of melts and MVPs we need experimental methods to simulate MVP exsolution that impose minimal external constraints on their equilibration. Previous experiments have focused on evaluating the exchange of elements between aqueous fluids and silicate melts under equilibrium conditions[1,2]. However, the large mass proportion of fluid to melt in these experiment designs is unrealistic. As a result, the idealized compositions of the aqueous fluids may exert a strong control on melt compositions for which they are out of equilibrium, especially at low melt fractions. In contrast, other experiments have focused on the melt during crystallization but must calculate MVP compositions by mass balance. In order to investigate MVPs and magmas during this critical period of MVP exsolution, we present a new two-stage fluid-melt experimental design. Stage one experiments generate super-liquidus hydrous melts using Laguna del Maule rhyolites and dactites, as analogues for ascending arc magmas. Stage two experiments allow aliquots of stage one melt/glass to crystallize and exsolve MVPs. The design then uses pressure cycling to promote infiltration of in-situ fractured quartz and traps the MVPs as synthetic fluid inclusions. We present results from trial stage 2 experiments, which produced synthetic fluid inclusions consistent with literature values of fluid-melt Cl partitioning and of sufficient size for LA-ICPMS analysis. Trace element partitioning for Li, Na, K, Cu, Mo, and Au will also be presented.  Candela P.A. and Holland H.D. (1984) GCA 48, 373-380  Simon et al. (2006) GCA 70, 5583-5600.

Behavioral momentum, which can be defined as the persistence of behavior under altered environmental contingencies, is derived from Newtonian physics and operant psychology, and has relevance to behavior therapy in terms of shaping strong behaviors and ensuring effective relapse prevention strategies. The present study investigated whether changing operant schedule contingencies affects how humans respond to different stimuli when reinforcement density is systematically manipulated. Fifteen subjects participated in a computer study, in which each of two keys in a baseline condition was associated with the same schedule of reinforcement, multiple variable interval schedules, the only difference being that one reinforcer was ten times larger than the other. After six sessions, the contingency schedule changed to either an extinction condition, a variable time schedule, or a changed variable interval schedule to assess how 'subjects' responses persisted when reinforcement contingencies were systematically changed. Results of this study were found to be consistent with the general predictions of behavioral momentum. Subjects not only biased responding in favor of the more densely reinforcing key, but when contingencies changed, subjects showed continued biased responding. Implications for behavioral momentum for behavior modification and behavior therapy are discussed, and it is concluded that behavioral momentum has significant implications for designing new and comprehensive behavior change programs.

Full Text Available The essential oils of fifteen Eucalyptus species harvested from the Jbel Abderrahman and Korbous arboreta (North East Tunisia were screened for their antibacterial activities by the agar disc diffusion method. Eighteen major components as identified by GC/FID and GC/MS were selected for a study of the chemical and biological activity variability. The main one was 1,8-cineole, followed by spathulenol, trans-pinocarveol, α-pinene, p-cymene, globulol, cryptone, β-phellandrene, viridiflorol, borneol, limonene and isospathulenol. The chemical principal component analysis identified five species groups and subgroups, where each group constituted a chemotype, however that of the values of zone diameter of the inhibition (zdi identified six groups of Eucalyptus oils, characterized by their antibacterial inhibition ability. The strongest activity was shown by E. platypus oil against Enterococcus faecalis and by E. lamannii oil against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. A correlation between the levels of some major components and the antibacterial activities was observed.
Specific absorbed fractions (PHI's) in various organs of the body (target organs) from sources of monoenergetic photons in various other organs (source organs) are tabulated. In this volume PHI-values are tabulated for a fifteen-year-old male or an adult female (55 to 58 kg). These PHI-values can be used in calculating the photon component of the dose-equivalent rate in a given target organ from a given radionuclide that is present in a given source organ. The International Commission on Radiological Protection recognizes that the endosteal, or bone surface, cells are the tissue at risk for bone cancer. We have applied the dosimetry methods developed for beta-emitting radionuclides deposited in bone to follow the transport of secondary electrons that were freed by photon interactions through the microscopic structure of the skeleton. With these methods we can estimate PHI in the endosteal cells and can better estimate PHI in the active marrow; the latter is overestimated with other methods of Snyder et al. at photon energies below 200 keV. 12 refs., 2 tabs

Full Text Available The present study aims at analysing the degree of deformity in leprosy cases diagnosed in children under 15 years old and its relationship with operational and epidemiological factors. This epidemiological cross-sectional study was carried out at municipalities of three microregions in a Brazilian hyperendemic area. Data between 1998 and 2010 was collected from the Information System for Notifiable Diseases database. The average coefficient of detection was 32.96/100.000 inhabitants; 7.61% of new cases were diagnosed in children under 15 years old; 5% in this age group were grade 2 deformity at diagnosis. Prevalence of leprosy cases in children under 15 years old with deformity was higher in males ( CI 95%: 1.09–6.45 and in multibacillary patients ( CI 95%: 3.54–60.87 and lower when the detection mode was passive ( CI 95%: 0.31–1.73. Such context suggests high transmissibility and early exposure to Mycobacterium leprae since a lot of cases were diagnosed in children under fifteen years old and the incubation period of the leprosy bacillus varies from 02 to 07 years. This situation contributes to maintaining the chain of disease transmission in the area and indicates that health care services should intensify leprosy control.
An accurate volume measurement system for plutonium nitrate solution stored in an accountability tank with dip-tubes has been developed and demonstrated over fifteen years at the Plutonium Conversion Development Facility of the Japan Atomic Energy Agency. As a result of calibrations during the demonstration, it was proved that measurement uncertainty practically achieved and maintained was less than 0.1% (systematic character) and 0.15% (random) as one sigma which was half of the current target uncertainty admitted internationally. It was also proved that discrepancy between measured density and analytically determined density was less than 0.002 g·cm-3 as one sigma. These uncertainties include effects by long term use of the accountability tank where cumulative plutonium throughput is six tons. The system consists of high precision differential pressure transducers and a dead-weight tester, sequentially controlled valves for periodical zero adjustment, dampers to reduce pressure oscillation and a procedure to correct measurement biases. The sequence was also useful to carry out maintenances safely without contamination. Longevity of the transducer was longer than 15 years. Principles and essentials to determine solution volume and weight of plutonium, measurement biases and corrections, accurate pressure measurement system, maintenances and diagnostics, operational experiences, evaluation of measurement uncertainty are described.

We wished to determine whether total knee replacement (TKA) performed by young surgeons increased rates of mortality and complications compared with TKA performed by senior surgeons using the same model of arthroplasty. There were no significant pre-operative differences between the groups in terms of age, gender, height, weight, body mass index, diagnosis, comorbidity and duration of follow-up, which was a mean of 15 years in both groups. Hence, we assessed the 15 year survival of the first 150 Ceraver Posterior-Stabilized total knee arthroplasties undertaken by young surgeons (aged of less than 30 years) in formation in a single university hospital setting (Group B). We used survival curve analysis, with strict definitions regarding end-points, and evaluated a number of different endpoint criteria to assess the outcome and to compare the results with those obtained by the two seniors (aged of more than 40 years) with their 50 first implantations (Group A). The clinical results and survival rate of implants at intermediate to long-term follow-up were similar in both Groups. Kaplan-Meier survival analysis, with revision as the endpoint for failure, showed that the rate of survival at ten years was 96% (95% CI, 93 to 100) in both groups. At fifteen years the rate of survival was 91% (95% CI, 85 to 97) in group B, and 92% (95% CI, 90 to 94) in group A. The implant used in this series appears particularly safe since the usual complications observed with posterior stabilized arthroplasties were not observed even with young surgeons. PMID:19572035

Preventive Child Health Care (PCHC) services are delivered to all children in the Netherlands by approximately 5500 doctors, nurses and doctor's assistants. In 1996, The Dutch Ministry of Health, Welfare and Sports asked for the development of evidence-based PCHC guidelines. Since 1998, twenty-five guidelines have been published. Levels of implementation affect outcomes and so implementation and evaluation of the actual use of guidelines are essential. At the outset, there was a national implementation plan with six main activities: a) determinant analysis before the implementation of a guideline, b) innovation strategies tailored to the determinants, c) dissemination to all professionals, d) ongoing evaluation of the awareness and use of the guidelines, e) trained implementation coordinator(s) in each PCHC organization and f) a national help desk. The awareness and use of the guidelines in random samples of doctors, nurses and doctor's assistants were surveyed using questionnaires. The respondents stated (on a 7-point scale) the proportion of all children they had exposed to given core elements in a guideline. The aim is for at least 90% of the professionals to be aware of the guideline and for 80% to perform the core elements for all (or nearly all) children. The six main activities, with the exception of ongoing evaluation, were gradually put into place, albeit only gradually, between 1998 and 2015 for all guidelines. In 2012, the use of individual core elements in all guidelines, dating from before 2012, varied from 28% to 100%. One guideline met both criteria of 90% awareness and 80% use, and three guidelines nearly met these criteria. Looking back on fifteen years of PCHC guidelines, we may conclude that the guidelines produced recently are implemented in accordance with the national implementation plan. Unfortunately, the evaluation of guideline use continues to be a difficulty. PMID:25982867
Full Text Available Orientation: The Fifteen Factor Questionnaire Plus (15FQ+ is a prominent personality questionnaire that organisations frequently use in personnel selection in South Africa.Research purpose: The primary objective of this study was to undertake a factor analytic investigation of the first-order factor structure of the 15FQ+.Motivation for the study: The construct validity of the 15FQ+, as a measure of personality, is necessary even though it is insufficient to justify its use in personnel selection.Research design, approach and method: The researchers evaluated the fit of the measurement model, which the structure and scoring key of the 15FQ+ implies, in a quantitative study that used an ex post facto correlation design through structural equation modelling. They conducted a secondary data analysis. They selected a sample of 241 Black South African managers from a large 15FQ+ database.Main findings: The researchers found good measurement model fit. The measurement model parameter estimates were worrying. The magnitude of the estimated model parameters suggests that the items generally do not reflect the latent personality dimensions the designers intended them to with a great degree of precision. The items are reasonably noisy measures of the latent variables they represent.Practical/managerial implications: Organisations should use the 15FQ+ carefully on Black South African managers until further local research evidence becomes available.Contribution/value-add: The study is a catalyst to trigger the necessary additional research we need to establish convincingly the psychometric credentials of the 15FQ+ as a valuable assessment tool in South Africa.

Leber's hereditary optic neuropathy (LHON) is an optic nerve dysfunction resulting from mutations in mitochondrial DNA (mtDNA), which is transmitted in a maternal pattern of inheritance. It is caused by three primary point mutations: G11778A, G3460A and T14484C; in the mitochondrial genome. These mutations are sufficient to induce the disease, accounting for the majority of LHON cases, and affect genes that encode for the different subunits of mitochondrial complexes I and III of the mitochondrial respiratory chain. Other mutations are secondary mutations associated with the primary mutations. The purpose of this study was to determine MT-ND variations in Iranian patients with LHON. In order to determine the prevalence and distribution of mitochondrial mutations in the LHON patients, their DNA was studied using PCR and DNA sequencing analysis. Sequencing of MT-ND genes from 35 LHON patients revealed a total of 44 nucleotide variations, in which fifteen novel variations-A14020G, A13663G, C10399T, C4932A, C3893G, C10557A, C12012A, C13934T, G4596A, T12851A, T4539A, T4941A, T13255A, T14353C and del A 4513-were observed in 27 LHON patients. However, eight patients showed no variation in the ND genes. These mutations contribute to the current database of mtDNA polymorphisms in LHON patients and may facilitate the definition of disease-related mutations in human mtDNA. This research may help to understand the disease mechanism and open up new diagnostic opportunities for LHON. PMID:24158608

With a flux of deeply derived fluids of ~5000 t/d and an energetic release of ~100 MW Solfatara of Pozzuoli is one of the largest studied volcanic-hydrothermal system of the world. Since 1998, soil CO2 flux surveys where performed using the accumulation chamber method over a large area (1.45 km2), including the volcanic apparatus and its surroundings. The statistical elaboration of CO2 flux, also coupled with the investigation of the CO2 efflux isotopic composition, allowed to characterize both the CO2 flux connected to by biological activity in the soil and that feed to the degassing of the hydrothermal system. A geostatistical elaboration of CO2 fluxes based on sequential Gaussian simulations, allowed to define the spatial structure of the degassing area, pointing out the presence of a well defined diffuse degassing structure interested by the release of deeply derived CO2 (Solfatara DDS). Solfatara DDS results well correlated to volcanic and tectonic structures interesting the crater area and the eastern area of Pisciarelli. With the same approach the total amount of CO2 release was estimated to range between 754 t/d and 1530 t/d in the last fifteen year (with an error in the estimate varying between 9 and 15 %). Also the extension of the DDS experienced relevant variations varying between 4.5x105 m2 to 12.3 x105 m2. In particular two major changes occurred in the extension of the DDS, the first consisted in its doubling in 2003-2004 and the second in further enlargement of ~ 30% in 2011-2012, the last occurring after period of decreasing trend which interrupted 4-5 years of relative stability. These variations mainly occurred external to the crater area in correspondence of a NE-SW fault system where fluxes increased from background to values typical of the endogenous source. The first event was previously correlated with the occurrence in 2000 of a relatively deep seismic swarm, which was interpreted as the indicator of the opening of an easy-ascent pathway

Full Text Available Neste artigo, analiso o modo como a questão racial tem marcado a política brasileira nos últimos quinze anos. Começo expondo o que significou a idéia de democracia racial no processo de construção da nacionalidade brasileira, para depois, com a brevidade que o espaço exige, resenhar os estudos sobre o comportamento eleitoral dos negros brasileiros e tratar da emergência de movimentos sociais negros e de sua incorporação ao sistema político. Meu entendimento é que devemos ver na "democracia racial" um compromisso político e social do moderno estado republicano brasileiro, que vigeu, alternando força e convencimento, do Estado Novo de Vargas até o final da ditadura militar. Tal compromisso, hoje em crise, consistiu na incorporação da população negra brasileira ao mercado de trabalho, na ampliação da educação formal, enfim na criação das condições infra-estruturais de uma sociedade de classes que desfizesse os estigmas criados pela escravidão. A imagem do negro enquanto povo comum e o banimento, no pensamento social brasileiro, do conceito de "raça", substituído pelos de "cultura" e "classe social", são as expressões maiores desse compromisso.In this article, I analyze how the racial question has marked Brazilian politics in the past fifteen years. I start by showing what the idea of racial democracy meant to the process of reconstruction of the Brazilian nationality, and go on to review the studies on the voting behaviour of the Brazilian Black population and discuss the emergence of Black social movements and their incorporation into the political system. I understand that we must see "racial democracy" as a political and social compromise of the Brazilian modern republican state, which was in power from the Vargas' New State until the end of the military dictatorship. This compromise which at present is in crisis, consisted of the incorporation of the Brazilian Black population into the work market, of the
The online Prescriptive Index platform for the assessment of managerial competencies and coaching needs: development and initial validation of the experience sampling Mood Wheel and the Manager-Rational and Irrational Beliefs Scale
Full Text Available The Prescriptive Index platform is dedicated to the appraisal and development of managerial competencies, and it is comprised of such measures as the multi-rater Freeman-Gavita Prescriptive Executive Coaching (PEC Assessment for assessing core managerial skills, and the multi-rater Managerial Coaching Assessment System (MCAS for the evaluation of coaching competencies in managers. The aim of this research was to present the development and psychometric properties of new tools, part of the Prescriptive Index platform, for the assessment of managerial emotional competencies: the web and mobile based Mood Wheel measure using experience sampling procedures, for the assessment of current/previous distress and positive emotions; and the self-report Manager Rational and Irrational Beliefs Scale (M-RIBS for the assessment of managerial attitudes involved in emotion-regulation processes. Results obtained show that both instruments integrated in the Prescriptive Index platform have adequate initial psychometric support and predictive validity. Practical implications of our findings are discussed in the light of the importance of enabling organizations to accurately identify managerial competencies and coaching needs.

A collaborative trial was conducted to evaluate the possibility of integrating the rat-liver Comet assay into repeat-dose toxicity studies. Fourteen laboratories from Europe, Japan and the USA tested fifteen chemicals. Two chemicals had been previously shown to induce micronuclei in an acute protocol, but were found negative in a 4-week Micronucleus (MN) Assay (benzo[a]pyrene and 1,2-dimethylhydrazine; Hamada et al., 2001); four genotoxic rat-liver carcinogens that were negative in the MN assay in bone marrow or blood (2,6-dinitrotoluene, dimethylnitrosamine, 1,2-dibromomethane, and 2-amino-3-methylimidazo[4,5-f]quinoline); three compounds used in the ongoing JaCVAM (Japanese Center for the Validation of Alternative Methods) validation study of the acute liver Comet assay (2,4-diaminotoluene, 2,6-diaminotoluene and acrylamide); three pharmaceutical-like compounds (chlordiazepoxide, pyrimethamine and gemifloxacin), and three non-genotoxic rodent liver carcinogens (methapyrilene, clofibrate and phenobarbital). Male rats received oral administrations of the test compounds, daily for two or four weeks. The top dose was meant to be the highest dose producing clinical signs or histopathological effects without causing mortality, i.e. the 28-day maximum tolerated dose. The liver Comet assay was performed according to published recommendations and following the protocol for the ongoing JaCVAM validation trial. Laboratories provided liver Comet assay data obtained at the end of the long-term (2- or 4-week) studies together with an evaluation of liver histology. Most of the test compounds were also investigated in the liver Comet assay after short-term (1-3 daily) administration to compare the sensitivity of the two study designs. MN analyses were conducted in bone marrow or peripheral blood for most of the compounds to determine whether the liver Comet assay could complement the MN assay for the detection of genotoxins after long-term treatment. Most of the liver genotoxins

Behavioral momentum, the persistence of behavior under altered environmental contingencies, is derived from Newtonian physics and operant psychology. It has relevance to behavior analysis in terms of shaping strong behaviors and ensuring effective relapse prevention strategies in behavior modification and therapy. The authors investigated whether changing the operant schedule contingencies affects the responses of older humans to different stimuli when reinforcement density is systematically manipulated. Fifteen older adults participated in a computer study in which each of 2 keys in a baseline condition was associated with the same schedule of reinforcement and multiple variable intervals; the only difference was that 1 reinforcer was 10 times larger than the other. After 6 sessions, the authors changed the contingency schedule to either an extinction condition, a variable-time schedule, or a different variable-interval schedule, to assess how participants' responses persisted when reinforcement contingencies were systematically changed. The results were consistent with the predictions of behavioral momentum. The participants not only biased their responses in favor of the more densely reinforcing key, but when contingencies changed, they showed significantly biased responses. Results supported the conclusion that healthy older adults allocate their behaviors in a manner very sensitive to training stimuli conditions; consistent with the basic principles of behavioral momentum, they show a degree of resistance to change in their behaviors when the behavioral contingencies are altered.

Attention deficit/hyperactivity disorder (ADHD) is a chronic and substantially impairing disorder. This means that treatment must also be chronic and substantial. Behavior Modification, and in many cases, the combination of behavior modification and stimulant medication, is a valid, useful treatment for reducing the pervasive impairment experienced by children with ADHD. Based on the research evidence reviewed, behavior modification should be the first line of treatment for children with ADHD. PMID:10944662

The justice literature has paid considerable attention to the beneficial effects of fair behaviors for recipients of such behaviors. It is possible, however, that exhibiting fair behaviors may come at a cost for actors. In this article, we integrate ego depletion theory with organizational justice research in order to examine the consequences of justice behaviors for actors. We used an experience-sampling method in a sample of managerial employees to examine the relations of performing procedural justice and interpersonal justice behaviors with subsequent changes in actors' regulatory resources. Our results indicate that procedural justice behaviors are draining, whereas interpersonal justice behaviors are replenishing for actors. Depletion, in turn, adversely affected the performance of citizenship behavior, and depletion mediated relations of justice behavior with citizenship. Furthermore, 2 traits that impact self-regulatory skills--extraversion and neuroticism--moderated the replenishing effects of engaging in interpersonal justice behaviors. We conclude by discussing implications and avenues for future research. PMID:24446913

According to situationism in psychology, behavior is primarily influenced by external situational factors rather than internal traits or motivations such as virtues. Environmental ethicists wish to promote pro-environmental behaviors capable of providing adequate protection for the environment, but...... situationist critiques suggest that character traits, and environmental virtues, are not as behaviorally robust as is typically supposed. Their views present a dilemma. Because ethicists cannot rely on virtues to produce pro-environmental behaviors, the only real way of salvaging environmental virtue theory is...... producing positive results. However, because endorsing behaviorally ineffective virtues, for whatever reason, entails that environmental ethicists are abandoning the goal of helping and protecting the environment, environmental ethicists should consider looking elsewhere than virtues and focus instead on...

Some relations between elasticity of demand and the conditions of reinforcement are reanalyzed in terms of resistance to change, in ways suggested by the metaphor of behavioral momentum; some relations between resistance to change and the conditions of reinforcement are reanalyzed in terms of elasticity of demand, in ways suggested by behavioral economics. In addition, some data on labor supply in relation to variable-ratio schedules and alternative reinforcement are reanalyzed in terms of resistance to change and compared with steady-state resistance data for performance on multiple and concurrent interval schedules. The results of these studies can be summarized by two functions based on the behavioral momentum approach, relating relative behavioral mass to relative reinforcement per response or per unit time. The former is a relation between relative unit price and relative behavioral mass, suggesting the possibility of convergent measurement of a theoretical construct common to both approaches. However, the momentum and economic approaches differ fundamentally on whether it is preferable to construe discriminated operant behavior as selected and strengthened by its consequences or as part of a behavior-consequence bundle that maximizes utility.

Oilseed rape is known to persist in arable fields because of its ability to develop secondary seed dormancy in certain agronomic and environmental conditions. If conditions change, rapeseeds are able to germinate up to 10 years later to build volunteers in ensuing crops. Extrapolations of experimental data acted on the assumption of persistence periods for more than 20 years after last harvest of rapeseed. Genetically-modified oilseed rape-cultivated widely in Northern America since 1996-is assumed not to differ from its conventional form in this property. Here, experimental data are reported from official monitoring activities that verify these assumptions. At two former field trial sites in Saxony-Anhalt genetically-modified herbicide-resistant oilseed rape volunteers are found up to fifteen years after harvest. Nevertheless, spatial dispersion or establishment of GM plants outside of the field sites was not observed within this period. PMID:26784233

The aim of the present study was to examine gender differences in children with inattention, hyperactivity, and impulsivity on the Five to Fifteen (FTF) parent questionnaire. First, non-referred girls (n = 43) and boys (n = 51) with problems of attention and hyperactivity-impulsivity and then...... questionnaire. Secondly, it was examined whether the application of gender mixed norms versus gender specific norms would result in varying proportions of clinic-referred children with HKD being identified as impaired on the subdomains of the FTF questionnaire. Based on results it was concluded that the use of...... a gender mixed normative sample may lead to overestimation of impairment in boys with HKD, but the type of sample applied to define impairment on the FTF should depend on the purpose for applying the questionnaire....

The authors combined affective events theory (H. M. Weiss & Cropanzano, 1996) and the transactional stress model (R. S. Lazarus & Folkman, 1984) to build and test a model specifying the dynamic, emotion-based relationships among challenge and hindrance stressors and citizenship and counterproductive behaviors. The study employed an experience sampling methodology. Results showed that challenge stressors had offsetting indirect links with citizenship behaviors through attentiveness and anxiety and a positive indirect effect on counterproductive behaviors through anxiety. Hindrance stressors had a negative indirect effect on citizenship behaviors through anxiety and a positive indirect effect on counterproductive behaviors through anxiety and anger. Finally, multilevel moderating effects showed that the relationship between hindrance stressors and anger varied according to employees' levels of neuroticism. PMID:19916654

OBJECTIVE We previously reported changes in food-cue neural reactivity associated with behavioral and surgical weight loss interventions. Resting functional connectivity represents tonic neural activity that may contribute to weight loss success. Here we explore whether intervention type is associated with differences in functional connectivity after weight loss. METHODS Fifteen obese participants were recruited prior to adjustable gastric banding surgery. Thirteen demographically matched obese participants were selected from a separate behavioral diet intervention. Resting state fMRI was collected three months after surgery/behavioral intervention. ANOVA was used to examine post-weight loss differences between the two groups in connectivity to seed regions previously identified as showing differential cue-reactivity after weight loss. RESULTS Following weight loss, behavioral dieters exhibited increased connectivity between left precuneus/superior parietal lobule (SPL) and bilateral insula pre- to post-meal and bariatric patients exhibited decreased connectivity between these regions pre- to post-meal (pcorrected<.05). CONCLUSIONS Behavioral dieters showed increased connectivity pre- to post-meal between a region associated with processing of self-referent information (precuneus/SPL) and a region associated with interoception (insula) whereas bariatric patients showed decreased connectivity between these regions. This may reflect increased attention to hunger signals following surgical procedures, and increased attention to satiety signals following behavioral diet interventions. PMID:26053145

Behavioral Economics is the combination of psychology and economics that investigates what happens in markets in which some of the agents display human limitations and complications. We begin with a preliminary question about relevance. Does some combination of market forces, learning and evolution render these human qualities irrelevant? No. Because of limits of arbitrage less than perfect agents survive and influence market outcomes. We then discuss three important ways in which humans devi...
This thesis aims to contribute to a further understanding of the real dynamics of OPEC production behavior and its impacts on the world oil market. A literature review in this area shows that the existing studies on OPEC still have some major deficiencies in theoretical interpretation and empirical estimation technique. After a brief background review in chapter 1, chapter 2 tests Griffin's market-sharing cartel model on the post-Griffin time horizon with a simultaneous system of equations, and an innovative hypothesis of OPEC's behavior (Saudi Arabia in particular) is then proposed based on the estimation results. Chapter 3 first provides a conceptual analysis of OPEC behavior under the framework of non-cooperative collusion with imperfect information. An empirical model is then constructed and estimated. The results of the empirical studies in this thesis strongly support the hypothesis that OPEC has operated as a market-sharing cartel since the early 1980s. In addition, the results also provide some support of the theory of non-cooperative collusion under imperfect information. OPEC members collude under normal circumstances and behave competitively at times in response to imperfect market signals of cartel compliance and some internal attributes. Periodic joint competition conduct plays an important role in sustaining the collusion in the long run. Saudi Arabia acts as the leader of the cartel, accommodating intermediate unfavorable market development and punishing others with a tit-for-tat strategy in extreme circumstances.

Full Text Available In the beginning of the spring Aristotelia chilensis sheds the old cohort, forms a new one and flowers. Fifteen days before the flowering and the fall we measured net photosynthesis (A, transpiration (E, water use efficiency (WUE, specific leaf mass (SLM and area and mass of leaves per branch in old and new cohorts. Under low irradiance the old cohort exhibited higher mean values of A and WUE on area bases (P<0.05. Under high irradiance A and WUE on mass bases were higher in new cohort due to its lower SLM (42.10 gm-2 in relation to old cohort (79.53 gm-2. Because old cohort showed 3.7 times more dry mass per branch it was able to counterbalance its lower performance on mass bases. It was concluded that old cohort was an important source of carbon during two powerful sink processes in the beginning of the spring: new leaves cohort construction and flowering.

The paper deals exclusively with the doctrine called ‘Logical Behaviorism’. Although this position does not vogue it enjoyed in the 1930s and 1940s, it will always possess a compelling attraction for anyone who is perplexed by the psychological concepts, who has become aware of worthlessness of an appeal to introspection as an account of how we learn those concepts, and he has no inclination to identify mind with brain. There, of course, are other forms of behaviorism, and of reductionism, wh...

It is well established that the serotonergic system modulates social and aggressive behaviors. This study employed field experiments to examine the effects of serotonin on male social structure and behavior in the Puerto Rican coquí frog, Eleutherodactylus coqui. This frog displays three types of male behavioral phenotypes: territorial, satellite, and paternal males. Territorial males produce advertisement calls that delineate territories and actively defend these areas. Satellite males typically do not call or defend given areas but are commonly within given conspecific territories. Paternal males brood and defend developing embryos typically in isolation. The objective of this investigation was to focus on territorial and satellite males to determine the impact of the serotonergic system on territorial behavior, specifically with regard to advertisement calling. Serotonin receptor subtype systems 5-HT(1A) and 5-HT(2A/C) were chosen due to their known function in behavioral regulation. Fifteen territorial and satellite males were injected with the 5-HT(1A) agonist 8-OH-DPAT and 15 territorial and satellite males were injected with the 5-HT(2A/C) agonist DOI. Control territorial and satellite males received saline injections. Results indicated that a significant number of territorial males injected with 8-OH-DPAT and DOI failed to emit territorial vocalizations and did not display dominant postural behaviors. It is hypothesized that 8-OH-DPAT and DOI activate 5-HT(1A) and 5-HT(2A/C) receptor systems, respectively, and this activation results in the elimination of territorial behavior resulting in subordinate status. It is concluded that the serotonergic system is essential for the manifestation of male social behavior in E. coqui. PMID:18554729

A survey of employee behavior was conducted at Los Alamos National Laboratory (LANL). The objective of this study was to evaluate the prevalence of ergonomic behavior that decreased the chance of having a work-related musculoskeletal disorder (WMSD) among employees. The null hypothesis was tested to determine if there was a significant difference in ergonomic behavior between trained and untrained employees. The LANL employees were stratified by job series and then randomly selected to participate. The data were gathered using an electronic self-administered behavior questionnaire. The study population was composed of 6931 employees, and the response rate was 48%. The null hypothesis was rejected for twelve out of fifteen questions on the questionnaire. Logistic regression results indicate that the trained participants were more likely to report the risk-avoiding behavior, which supported the rejection of the null hypothesis for 60% of the questions. There was a higher frequency that the beneficial or risk-avoiding behavior was reported by the uninjured participants. Job series analysis revealed that ergonomics is an important issue among participants from all the job series. It also identified the occupational specialist classification (an administrative job), as the job series with the most occurrences of undesired ergonomic behaviors. In conclusion, there was a significant difference between the trained and untrained participants of the beneficial ergonomic behavior in the reported risk reducing behaviors.
Beginning with behavior analysts' tendency to characterize verbal behavior as “mere” verbal behavior, the author reviews his own attempt to employ it to influence both his staff and policies of our government. He then describes its role in psychopathology, its effect on speakers in healing themselves and on engendering creativity. The paper ends by calling to our attention the role of verbal behavior in the construction of behavior analysis.

Integrating insights from the literature on customers' central role in service and the literature on employee creativity, we offer theoretical and empirical account of how and when customer empowering behaviors can motivate employee creativity during service encounters and, subsequently, influence customer satisfaction with service experience. Using multilevel, multisource, experience sampling data from 380 hairstylists matched with 3550 customers in 118 hair salons, we found that customer empowering behaviors were positively related to employee creativity and subsequent customer satisfaction via employee state promotion focus. Results also showed that empowering behaviors from different agents function synergistically in shaping employee creativity: supervisory empowering leadership strengthened the indirect effect of customer empowering behaviors on employee creativity via state promotion focus.

The joint influence of persons and situations on behavior has long been posited by personality and social psychological theory (Funder, 2006; Lewin, 1951). However, a lack of tools for real-time behavioral and situation assessment has left direct investigations of this sort immobilized. This study combines recent advances in situation assessment and experience sampling methodology to examine the simultaneous effects of personality traits and situation characteristics on real-time expressions of behavior and emotion in N = 210 participants. The results support an additive model such that both personality traits and situation characteristics independently predict real-time expressions of behavior and emotion. These results have implications for several prominent theoretical perspectives in personality, including both trait and cognitive theories. PMID:25915131

A descriptive study was carried out comprising forty-five patients diagnosed and treated in Paracatu between 1994 and 2001. Fifty-three percent of diagnoses were in male children, 75.5% of the cases being between ten and fourteen years of age; individuals had less years of schooling than what would be expected for their ages; 84% of the population lived in the urban area. All patients included (100% were new cases, of which 56% were multibacillary forms, mainly the Dimorph clinical form (potentially infectious, followed by the Undetermined (30.8% and Tuberculoid (13.2% forms. All were treated according to standard procedures, with a 100% cure rate. During treatment 24% of patients presented reactions, and 9% did after being discharged. Twenty-two percent of patients were diagnosed with some degree of disability, and 13% presented some degree of disability upon discharge (a rate considered high. Sixty-two percent of patients had contact with other Hansen's disease bearers, and only 15.5% of these contacts had two BCG vaccine scars. Leprosy is a serious public health problem in the city studied, and the work accomplished with students was primary to increase case detection.

Full Text Available Behaviorism has argued that behavior is the Psyche and the subject matter of psychology. Although, some scientists had done empirical work with objective methods before 1913, the year in which John B. Watson published his manifesto, he was the first one to attempt a systematization of behavior as the Psyche, that is, as psychology’s subject matter. In this text, I outline Watson’s notion of behavior to compare it with two other forms of behaviorism: Skinner’s radical behaviorism and molar behaviorism. The purpose of the paper is to illustrate how the concept of behavior has been and is changing.

Full Text Available At a fundamental level, taxonomy of behavior and behavioral tendencies can be described in terms of approach, avoid, or equivocate (i.e., neither approach nor avoid. While there are numerous theories of personality, temperament, and character, few seem to take advantage of parsimonious taxonomy. The present study sought to implement this taxonomy by creating a questionnaire based on a categorization of behavioral temperaments/tendencies first identified in Buddhist accounts over fifteen hundred years ago. Items were developed using historical and contemporary texts of the behavioral temperaments, described as "Greedy/Faithful", "Aversive/Discerning", and "Deluded/Speculative". To both maintain this categorical typology and benefit from the advantageous properties of forced-choice response format (e.g., reduction of response biases, binary pairwise preferences for items were modeled using Latent Class Analysis (LCA. One sample (n1 = 394 was used to estimate the item parameters, and the second sample (n2 = 504 was used to classify the participants using the established parameters and cross-validate the classification against multiple other measures. The cross-validated measure exhibited good nomothetic span (construct-consistent relationships with related measures that seemed to corroborate the ideas present in the original Buddhist source documents. The final 13-block questionnaire created from the best performing items (the Behavioral Tendencies Questionnaire or BTQ is a psychometrically valid questionnaire that is historically consistent, based in behavioral tendencies, and promises practical and clinical utility particularly in settings that teach and study meditation practices such as Mindfulness Based Stress Reduction (MBSR.

Full Text Available La leptospirosis es una enfermedad infecciosa, transmisible de alta prevalencia en bovinos y porcinos, por lo cual se presume que la prevalencia de la infección por leptospira, en personas de riesgo, es también alta. Este trabajo se realizó con trabajadores de 15 granjas porcinas y de una planta de sacrificio de bovinos y porcinos. Los trabajadores fueron sangrados tres veces, con dos meses de intervalo, para obtener la prevalencia puntual a leptospirosis, por el MAT 1/50 y por la Inhibición de Crecimiento (IC 1/25. Se tomaron además muestras de orina, para Visualización Directa (VD en campo oscuro y cultivo. Las prevalencias obtenidas por el MAT fueron muy bajas en ambos grupos, siendo más altas por la IC, y más altas aún por la VD y por el cultivo. Este último es la técnica más confiable para el diagnóstico, en tanto que el MAT detecta infecciones agudas, pero no es adecuado para la detección de infecciones crónicas. El serovar más prevalente en los dos grupos estudiados fue hardjopratjino, en tanto que los trabajadores del matadero fueron positivos además, a pomona, grippotyphosa, bratislava y hardjobovis, y los de granjas porcinas a canicola e icterohaemorragiae, esta última no detectada en trabajadores del matadero.

Although the study of helping behavior has revolutionized the field of behavioral ecology, scientific examination of rescue behavior remains extremely rare, except perhaps in ants, having been described as early as 1874. Nonetheless, recent work in our laboratories has revealed several new patterns of rescue behavior that appear to be much more complex than previously studied forms. This precisely-directed rescue behavior bears a remarkable resemblance to what has been labeled empathy in rats, and thus raises numerous philosophical and theoretical questions: How should rescue behavior (or empathy) be defined? What distinguishes rescue from other forms of altruism? In what ways is rescue behavior in ants different from, and similar to, rescue in other non-human animals? What selection pressures dictate its appearance? In this paper, we review our own experimental studies of rescue in both laboratory and field, which, taken together, begin to reveal some of the behavioral ecological conditions that likely have given rise to rescue behavior in ants. Against this background, we also address important theoretical questions involving rescue, including those outlined above. In this way, we hope not only to encourage further experimental analysis of rescue behavior, but also to highlight important similarities and differences in very distant taxa. PMID:23864298

Full Text Available Insects encounter a vast repertoire of chemicals in their natural environment, which can signal positive stimuli like the presence of a food source, a potential mate, or a suitable oviposition site as well as negative stimuli such as competitors, predators, or toxic substances reflecting danger. The presence of specialized chemoreceptors like taste and olfactory receptors allow animals to detect chemicals at short and long distances and accordingly, trigger proper behaviors towards these stimuli. Since the first description of olfactory and taste receptors in Drosophila fifteen years ago, our knowledge on the identity, properties, and function of specific chemoreceptors has increased exponentially. In the last years, multidisciplinary approaches combining genetic tools with electrophysiological techniques, behavioral recording, evolutionary analysis, and chemical ecology studies are shedding light on our understanding on the ecological relevance of specific chemoreceptors for the survival of Drosophila in their natural environment. In this review we discuss the current knowledge on chemoreceptors of both the olfactory and taste systems of the fruitfly. We focus on the relevance of particular receptors for the detection of ecologically relevant cues such as pheromones, food sources, and toxic compounds, and we comment on the behavioral changes that the detection of these chemicals induce in the fly. In particular, we give an updated outlook of the chemical communication displayed during one of the most important behaviors for fly survival, the courtship behavior. Finally, the ecological relevance of specific chemicals can vary depending on the niche occupied by the individual. In that regard, in this review we also highlight the contrast between adult and larval systems and we propose that these differences could reflect distinctive requirements depending on the change of ecological niche occupied by Drosophila along its life cycle.

In this review, we discuss the emerging field of computational behavioral analysis-the use of modern methods from computer science and engineering to quantitatively measure animal behavior. We discuss aspects of experiment design important to both obtaining biologically relevant behavioral data and enabling the use of machine vision and learning techniques for automation. These two goals are often in conflict. Restraining or restricting the environment of the animal can simplify automatic behavior quantification, but it can also degrade the quality or alter important aspects of behavior. To enable biologists to design experiments to obtain better behavioral measurements, and computer scientists to pinpoint fruitful directions for algorithm improvement, we review known effects of artificial manipulation of the animal on behavior. We also review machine vision and learning techniques for tracking, feature extraction, automated behavior classification, and automated behavior discovery, the assumptions they make, and the types of data they work best with.

The shift to use environmentally friendly technologies throughout future space-related launch programs prompted a study aimed at replacing current petroleum and solvent-based Corrosion Preventive Compounds (CPCs) with environmentally friendly alternatives. The work in this paper focused on the identification and evaluation of environmentally friendly CPCs for use in protecting flight hardware and ground support equipment from atmospheric corrosion. The CPCs, while a temporary protective coating, must survive in the aggressive coastal marine environment that exists throughout the Kennedy Space Center, Florida. The different protection behaviors of fifteen different soft film CPCs, both common petroleum-based and newer environmentally friendly types, were evaluated on various steel and aluminum substrates. The CPC and substrate systems were subjected to atmospheric testing at the Kennedy Space Center's Beachside Atmospheric Corrosion Test Site, as well as cyclic accelerated corrosion testing. Each CPC also underwent physical characterization and launch-related compatibility testing . The initial results for the fifteen CPC systems are reported : Key words: corrosion preventive compound, CPC, spaceport, environmentally friendly, atmospheric exposure, marine, carbon steel, aluminum alloy, galvanic corrosion, wire on bolt.

Employee characteristics and general attitudes towards safety and work condition are included in the extended model. A survey was handed out to 654 employees in Chinese factories. This research contributes by demonstrating how employee- characteristics and general attitudes towards safety and work...... condition influence their sustainable work behavior. A new definition of sustainable work behavior is proposed....
Full Text Available The aim of this paper was to explore whether there are significant differences between those who have never engaged in sexting behavior and those who have for at least once in any number of variables: sexual risk behavior, anger, depression, anxiety, self-efficacy and association with deviant peers. Also, the goal was to explore whether anger and unpleasant emotions of depression and anxiety are significant predictors of sexting and whether self-efficacy and association with deviant peers express moderator role in the relationship between enlisted predictors and sexting. Analyzed data were collected in 2012 from 311 students (149 boys, 162 girls, aged between fifteen and seventeen years. The results of series of independent t-tests showed significant differences between the two groups in sexual risk behavior and deviant peers association, whereby those who have engaged in sexting behavior at least once, compared to those who have never sexted, engaged more frequently in sexual risk behaviors and have more deviant friends. The results of hierarchical binary logistic regression analysis showed that sexting was not significantly predicted by anger, depression and anxiety and that self-efficacy and association with deviant peers do not change the relationship between anger and sexting, as well as the relationship between unpleasant emotions of depression or anxiety and sexting. The results are discussed in terms of findings of previous research and in the context of the relationship between the variables specified in the context of Agnew's (1992 general strain theory.
Full Text Available Parasites can dramatically reduce the fitness of their hosts, and natural selection should favor defense mechanisms that can protect hosts against disease. Much work has focused on understanding genetic and physiological immunity against parasites, but hosts can also use behaviors to avoid infection, reduce parasite growth or alleviate disease symptoms. It is increasingly recognized that such behaviors are common in insects, providing strong protection against parasites and parasitoids. We review the current evidence for behavioral immunity in insects, present a framework for investigating such behavior, and emphasize that behavioral immunity may act through indirect rather than direct fitness benefits. We also discuss the implications for host-parasite co-evolution, local adaptation, and the evolution of non-behavioral physiological immune systems. Finally, we argue that the study of behavioral immunity in insects has much to offer for investigations in vertebrates, in which this topic has traditionally been studied.
Behavioral economics has been a growing force in many fields of applied economics, including public economics, labor economics, health economics, and law and economics. This paper describes and assesses the current state of behavioral law and economics. Law and economics had a critical (though underrecognized) early point of contact with behavioral economics through the foundational debate in both fields over the Coase theorem and the endowment effect. In law and economics today, both the end...

Transsexualism is a rare disorder, and there is little literature available on its treatment. A case is presented of transsexualism with homosexual orientation in a 24 year old male. Since the disorder appeared to have behavioral antecedents, it was treated with a behavior therapy package comprising relaxation, aversion therapy with aversion relief, modelling, hypnosis, orgasmic reconditioning, behavioral counselling and sex education. Therapy resulted in normalization of gender identity, but...

Reward learning represents a crucial mechanism in the acquisition and maintenance of addictive behavior. The underlying neurobiological foundations and associated neurobiological pathways are identified in this review and similarities between substance abuse and behavioral addictions will be discussed. In the second section current neuroimaging findings on neurobiological mechanisms of pathological gambling and computer and internet addiction are discussed. The main focuses are on changes in neurocognitive processes, such as cue reactivity, reward and punishment processing and behavioral control. PMID:23632569
Behavioral economics has in recent decades emerged as a prominent set of methodological developments that have attracted considerable attention both within and outside the economics profession. The time is therefore auspicious to assess behavioral contributions to particular subfields of economics such as labor economics. With empirical validity among its chief objectives, one might guess that behavioral economics would have made its clearest mark in data-driven subfields such as labor econom...

The concept of contingency is central to theoretical discussions of learned behavior and in the application of learning research to problems of social significance. This paper reviews three aspects of the contingency concept as it has been developed by behavior analysts. The first is the empirical analysis of contingency through experimental studies of both human and nonhuman behavior. The second is the synthesis of experimental studies in theoretical and conceptual frameworks to yield a more...

According to cultural materialism, cultural practices result from the materialistic outcomes of those practices, not from sociobiological, mentalistic, or mystical predispositions (e.g., Hindus worship cows because, in the long run, that worship results in more food, not less food). However, according to behavior analysis, such materialistic outcomes do not reinforce or punish the cultural practices, because such outcomes are too delayed, too improbable, or individually too small to directly reinforce or punish the cultural practices (e.g., the food increase is too delayed to reinforce the cow worship). Therefore, the molar, materialistic contingencies need the support of molecular, behavioral contingencies. And according to the present theory of rule-governed behavior, the statement of rules describing those molar, materialistic contingencies can establish the needed molecular contingencies. Given the proper behavioral history, such rule statements combine with noncompliance to produce a learned aversive condition (often labeled fear, anxiety, or guilt). The termination of this aversive condition reinforces compliance, just as its presentation punishes noncompliance (e.g., the termination of guilt reinforces the tending to a sick cow). In addition, supernatural rules often supplement these materialistic rules. Furthermore, the production of both materialistic and supernatural rules needs cultural designers who understand the molar, materialistic contingencies. PMID:22478012

Full Text Available In article Ajzen-Fishbein's attitude-behavior model called 'Theory of reasoned action' and Albert Bandura's Model of reciprocal determinism are presented. Both models are a part of social-cognitive paradigm which characterizes behavior with evaluation of different goals. Ajzen and Fishbein (1973; 1980 proposed that specific behavior are predictable from specific behavioral intentions. These intentions are a function of two components: the attitude toward the act in question and percieved normative expectations of reference group. On the other hand Bandura (1986; 1997 claims that person's motivation for a specific behavior and direction toward a specific social object respectively, reflects perception of his or hers self-efficacy beliefs. Some of the findings concerning the synthesis of the two models are also reviewed.

Full Text Available Abstract Background The association between fire-setting behavior and psychiatric or medical disorders remains poorly understood. Although a link between fire-setting behavior and various organic brain disorders has been established, associations between fire setting and focal brain lesions have not yet been reported. Here, we describe the case of a 24-year-old first time arsonist who suffered Todd’s paralysis prior to the onset of a bizarre and random fire-setting behavior. Case presentation A case of a 24-year-old man with a sudden onset of a bizarre and random fire-setting behavior is reported. The man, who had been arrested on felony arson charges, complained of difficulties concentrating and of recent memory disturbances with leg weakness. A video-EEG recording demonstrated a close relationship between the focal motor impairment and a clear-cut epileptic ictal discharge involving the bilateral motor cortical areas. The SPECT result was statistically analyzed by comparing with standard SPECT images obtained from our institute (easy Z-score imaging system; eZIS. eZIS revealed hypoperfusion in cingulate cortex, basal ganglia and hyperperfusion in frontal cortex,. A neuropsychological test battery revealed lower than normal scores for executive function, attention, and memory, consistent with frontal lobe dysfunction. Conclusion The fire-setting behavior and Todd’s paralysis, together with an unremarkable performance on tests measuring executive function fifteen months prior, suggested a causal relationship between this organic brain lesion and the fire-setting behavior. The case describes a rare and as yet unreported association between random, impulse-driven fire-setting behavior and damage to the brain and suggests a disconnection of frontal lobe structures as a possible pathogenic mechanism.

Deeper and more detailed knowledge as to how human operators such as pilots respond, singly and in groups, to demands on their performance which arise from technical systems will support the manipulation of such systems' design in order to accommodate the foibles of human behavior. Efforts to understand how self-autonomy impacts strategic behavior and such related issues as error generation/recognition/correction are still in their infancy. The present treatment offers both general and aviation-specific definitions of strategic behavior as precursors of prospective investigations.

Studies involving mouse inbred strain comparisons and genetic analyses, and their impact on elucidation of taste receptors and transduction mechanisms are discussed. Finally, the effect of genetic variation in taste responsiveness on complex traits such as drug intake is considered. Recent advances in development of genomic resources make behavioral genetics a powerful approach for understanding mechanisms of taste.

It is fashionable to criticize economic theory for focusing too much on rationality and ignoring the imperfect and emotional way in which real economic decisions are reached. All of us facing the global economic crisis wonder just how rational economic men and women can be. Behavioral economics — an effort to incorporate psychological ideas into economics — has become all the rage. In this book, David K. Levine questions the idea that behavioral economics is the answer to economic problems. H...

This study revisits different experimental data sets that explore social behavior in economic games and uncovers that many treatment effects may be gender-specific. In general, men and women do not differ in “neutral” baselines. However, we find that social framing tends to reinforce prosocial behavior in women but not men, whereas encouraging reflection decreases the prosociality of males but not females. The treatment effects are sometimes statistically different across genders and sometime...

Although we may have formalized and systematized the field of behavior modification in the last few decades, people around the world have been using behavioral change strategies throughout history. Premack's (1965) theory of reinforcement is often called "Grandma's rule" because grandmothers have long been using it (e.g. You must finish your vegetables before you may go out and play). Franks (1969, p. 4), in one of the first behavioral texts, gave historical examples from China, Turkey, France, and Italy. Knapp and Shodahl (1974) showed how Benjamin Franklin used behavior modification. And de Silva (1984, 1985) gave examples of behavior modification by the Buddha and other early Buddhists. Conspicuously absent from our literature are examples from the Judeo-Christian tradition. In this paper, we provide a number of behavior modification examples from the Bible (New International Version). Footnotes provide references for many more examples. In the discussion, we explore implications for education and therapy. Examples are grouped by the following categories: operant conditioning, respondent conditioning, modeling, and cognitive interventions. However, the Biblical examples, like contemporary case studies, do not always fall neatly into discrete categories. They often are a combination, particularly operant and respondent conditioning interweaving. PMID:8826763

The legitimacy of nonsubstance addictions has received increased attention from clinicians, researchers and the general population as more and more individuals report symptoms consistent with impairment of impulse control. The clinical presentation of these disorders is varied, as compulsive activities may include: gambling, eating, sex, shopping, use of the Internet or videogames or even exercising, working or falling in love. As such, there is great controversy in diagnosing, treating or even naming these conditions, as many of these behaviors are daily rituals instrumental to our ultimate survival. Historically, the phrase "impulse control disorders" described these conditions but many researchers and clinicians also use the term "behavioral addictions," "process addictions" or "impulsive-compulsive behaviors" to report behavioral pathology. This review summarizes the data of each of these behavioral addictions from epidemiology to neurobiology to treatment options. Research suggests similarities between natural and drug reward processing but clinical evidence supports the utilization of treatment modalities for these behavioral conditions that can sometimes differ from traditional drug treatment.

Patients at risk of developing oral and/or oropharyngeal cancer (OPC) are more likely to see primary care providers (PCPs) than a dentist. Many PCPs do not regularly perform oral cancer examination (OCE). The purpose of this study was to design a web-based educational program based on a behavioral framework to encourage PCPs to conduct OCE. PCPs were solicited to provide feedback on the program and to evaluate their short-term knowledge. The integrated behavioral model was used to design the program. Fifteen PCPs (five in each group: physicians, physician assistants, and nurse practitioners) reviewed the program and took a posttest: (1) index of knowledge of risk factors for oral cancer (RiskOC) and (2) index of knowledge of diagnostic procedures for oral cancer (DiagOC). Findings from the process evaluation were mainly positive, with comments on the length of the program comprising the ten negative comments. No significant difference among groups of PCPs (physicians, physician assistants, and nurse practitioners) was detected for DiagOC (p = 0.43) or RiskOC (p = 0.201). A program on OPC for PCPs should be less than 40 min. Postviewing knowledge outcomes were similar for all PCPs. The web-based program on OPC based on a behavioral framework could have similar short-term knowledge outcomes for all PCPs and may increase the number of PCPs performing OCEs. PMID:25572460

Escape behaviors are, by necessity, fast and robust, making them excellent systems with which to study the neural basis of behavior. This is especially true in insects, which have comparatively tractable nervous systems and members who are amenable to manipulation with genetic tools. Recent technical developments in high-speed video reveal that, despite their short duration, insect escape behaviors are more complex than previously appreciated. For example, before initiating an escape jump, a fly performs sophisticated posture and stimulus-dependent preparatory leg movements that enable it to jump away from a looming threat. This newfound flexibility raises the question of how the nervous system generates a behavior that is both rapid and flexible. Recordings from the cricket nervous system suggest that synchrony between the activity of specific interneuron pairs may provide a rapid cue for the cricket to detect the direction of an approaching predator and thus which direction it should run. Technical advances make possible wireless recording from neurons while locusts escape from a looming threat, enabling, for the first time, a direct correlation between the activity of multiple neurons and the time-course of an insect escape behavior.

Epilepsy is defined as two or more unprovoked seizures. Epileptic patients have intellectual disability and behavioral co-morbidities to the tune of up to 25 and 75% respectively. Various factors like underlying etiology, socioeconomic environment at home, age at onset, seizure semiology, seizure descriptors like duration, severity and frequency, therapy related adverse effects secondary to antiepileptic drugs and epilepsy surgery have been implicated for the causation of cognitive and behavioral impairment in epilepsy. Cognitive epilepsy has emerged as a specific entity. This may manifest as a transient behavioral or cognitive change, insidous onset subacute to chronic encephalopathy or more catastrophic in the form of nonconvulsive status epilepticus. Cognitive impairment seen in epileptic children include difficulties in learning, memory, problem solving as well as concept formation. Anxiety, depression and attention deficit hyperkinetic disorders are the most common psychiatric co-morbidities seen. Investigating a child with epilepsy for cognitive and behavioral impairment is difficult as these tests would require cooperation from the patient's side to a significant extent. A rational approach towards treatment would be judicious selection of antiepileptic drugs, treatment of underlying cause, appropriate management of behavioral co-morbidities including psychopharmacotherapy and a trial of immunotherapy (particularly in cognitive epilepsies), wherever appropriate.

Previous neuroimaging studies on empathy have not clearly identified neural systems that support the three components of empathy: affective congruence, perspective-taking, and prosocial motivation. These limitations stem from a focus on a single emotion per study, minimal variation in amount of social context provided, and lack of prosocial motivation assessment. In the current investigation, 32 participants completed a functional magnetic resonance imaging session assessing empathic responses to individuals experiencing painful, anxious, and happy events that varied in valence and amount of social context provided. They also completed a 14-day experience sampling survey that assessed real-world helping behaviors. The results demonstrate that empathy for positive and negative emotions selectively activates regions associated with positive and negative affect, respectively. In addition, the mirror system was more active during empathy for context-independent events (pain), whereas the mentalizing system was more active during empathy for context-dependent events (anxiety, happiness). Finally, the septal area, previously linked to prosocial motivation, was the only region that was commonly activated across empathy for pain, anxiety, and happiness. Septal activity during each of these empathic experiences was predictive of daily helping. These findings suggest that empathy has multiple input pathways, produces affect-congruent activations, and results in septally mediated prosocial motivation. PMID:22887480

Positive behavior support (PBS) is an approach to providing services to individuals who exhibit challenging behavior. Since its inception in the early 1990s, PBS has received increasing attention from the behavior-analytic community. Some behavior analysts have embraced this approach, but others have voiced questions and concerns. In this paper we describe the framework of PBS and show that it is consistent with the tenets of behavior analysis. Also, we illustrate how the framework of PBS mig...

During the last decade knowledge about human behavior from psychology and sociology has enhanced the field of economics of education. By now research recognizes cognitive skills (as measured by achivement tests) as equally important drivers of later economic outcomes, and skills are seen as multi......-dimensional rather than one-dimensional. Explicitly accounting for soft skills often implies departing from the standard economic model by integrating concepts studied in behavioral and experimental economics, such as self-control, willingness to compete, intrinsic motivation, and self-confidence. We review how...... approaches from behavioral economics help our understanding of the complexity of educational investments and outcomes, and we discuss what insights can be gained from such concepts in the context of education....
Full Text Available Data mining (DM techniques make efforts to discovery knowledge from data. Aiming to finding patterns, association rule (AR computing algorithms seem to be one to be adopted on variety applications. To be originally claimed for best analyzing customer shopping goods in baskets, Apriori, the first AR algorithm, has been discussed and modified the most by researchers. This study adopts Apriori algorithm to forecast individual customer shopping behavior. This study finds that customer shopping behaviors can be comprehended better in a long run. With Apriori mining and the examining principles proposed by this study, customer purchase behaviors of no matter constant purchase, stopping purchasing habitual goods, and starting to purchase goods that never bought before is able to be recognized. However, impulse purchase, including purchase for holidays, is unable to be discovered.

Full Text Available Without any doubt, sport has become a major consumer market, either we discuss about practicing any kind of sport at professional or amateur level, or we are just interested by a competition, sport organization or an athlete as a regular consumer. From this last perspective, we can distinguish between two types of behaviors, respectively the spectator and the supporter or fan. Each of these two typologies has its own characteristics which define, in a significant manner, the consumer behavior. A correct understanding and management of this phenomenon, of the factors that influence the attitudes and the decisions taken by the respective consumer, of the display manner for the consumer behavior have a major importance from the management and marketing point of view. This paper focuses on the football consumer and describes, first of all, the main characteristics of each of the typologies mentioned above from this perspective, presenting also the reasons for their transition from passive supporter to fan. Another issue we approach in the current paper refers to the changes appeared in the consumer behavior when the market segment is represented by those supporters whose teams are either relegated or liquidated, which is a global phenomenon in the football area. Having in mind this aspect and taking into consideration the influence of media (TV, press, Internet, social media etc, some individual benchmarks that influence those consumer’s behavior are identified within the context of the general typologies previously mentioned. These influences help the consumer to obtain benefits or satisfaction similar to those already lost. The findings may be used in further research focused on that particular market segment and could provide the necessary support data for further development of proper techniques and tools for reshaping and changing the respective consumer behavior.
The starry sky is, unofficially but indubitably, a site of special scientific interest and an area of outstanding natural beauty - if it can be seen. The BAA's Campaign for Dark Skies (CfDS) was set up by concerned members in 1989, to counter the ever-growing tide of skyglow which has tainted the night sky over Britain since the 1950s. Once caused almost exclusively by poorly aimed streetlamps and building floodlights emitting light above the horizontal, skyglow is nowadays increasingly the result of vastly over-powered, poorly mounted household security lights and literally 'over-the-top' sports lighting. CfDS has grown into a network of 124 volunteer local officers, and several hundred committed supporters, who aim to persuade their local councils and relevant organisations of the benefits of well directed lighting, the motto being: the right amount of light, and only where needed.

We investigate both the physical and algorithmic requirements for an implementation of Shor's factorization algorithm on a hypothetical Josephson charge qubit register. We represent an implementation which is optimal for small number of available qubits, but still provides a general method to factorize integer without a prior knowledge of the number to be factorized. Furthermore, our strategy is easily generalized to other realizations and parameter values. In order to meet the stringent requirements set by short decoherence time, we accelerate the algorithm by decomposing it into tailored two- and three-qubit gates and find their physical realizations through the numerical optimization.
It is no surprise to many of Superfund's practitioners that the law and its application are flawed. The South Valley Superfund Site in Albuquerque, New Mexico has not escaped Superfund's problems. The problems and issues arising out of the South Valley Superfund site have spurred the desire to seek a better way to administer and manage cleanup. This new method applies organizational and role changes that bring Superfund closer to an efficient business-like entity. This ''Reengineered'' Superfund strives for reorganization, contractor reduction, improved communication, reporting reduction, and teaming. In addition, modifications are made to the roles of regulators, potentially responsible parties (PRPs), and the public. Today the site encompasses roughly one square mile in area, includes six identified contaminant sources, and deals with solvent and petroleum by-product contamination

European and international standards lay down criteria for the size-selective aerosol sampling in occupational hygiene. Aerosol samplers are supposed to match these target sampling criteria. This study focused on 15 aerosol samplers used to sample the conventional respirable fraction. An aerodynamic particle sizer (APS) method was used to measure the sampling efficiency of the samplers in a low-velocity wind tunnel. Polydisperse coal dust was generated as the test aerosol. The data were fitted by an appropriate mathematical model. For some instruments the results show serious deviations from the conventional target curve, whereas other devices meet the convention quite well. The flow rate of certain cyclone-separator-based instruments was optimized to adjust their sampling efficiency. The mass concentration bias and accuracy of the samplers were calculated for a number of ranges of particle size distributions of aerosols commonly found in industrial workplaces. Finally, the performance of each sampler was evaluated using bias and accuracy maps. Most of these samplers are suitable for sampling the CEN-ISO-ACGIH respirable fraction of aerosols, but several require modification of the flow rate. For real industrial situations, the rough knowledge of the aerosol size distribution can guide the choice of an appropriate sampling technique. PMID:11137698

Humans are transforming the biosphere in unprecedented ways, raising the important question of how these impacts are changing biodiversity. Here we argue that our understanding of biodiversity trends in the Anthropocene, and our ability to protect the natural world, is impeded by a failure to consider different types of biodiversity measured at different spatial scales. We propose that ecologists should recognize and assess 15 distinct categories of biodiversity trend. We summarize what is known about each of these 15 categories, identify major gaps in our current knowledge, and recommend the next steps required for better understanding of trends in biodiversity.

Full Text Available We report the case of a 73-year-old man who presented with an asymptomatic hepatic mass during investigation of mild chronic obstructive pulmonary disease by a plain chest radiograph, followed by ultrasonography, which revealed a solitary hepatic lesion measuring 7.1 cm × 6.5 cm × 5.8 cm in dimension. Fine- needle aspiration of the mass revealed malignant cells compatible with hepatocellular carcinoma. Interestingly, the patient had a left adrenalectomy and complete left nephrectomy in 1987, for a non-functioning left adrenocortical carcinoma (ACC. The ACC was diagnosed as stage two, with no evidence of local invasion or distant metastases. No adjuvant therapy was recommended postoperatively. After a five-year follow-up, there was no evidence of ACC recurrence and the patient was declared cured from his ACC. The patient underwent a complete segmental resection of the right lobe of the liver successfully. The final diagnosis of the mass was a well-differentiated metastatic adrenocortical carcinoma.

This anniversary paper is an occasion to recall some of the events that shaped institutional econophysics. But in these thoughts about the evolution of econophysics in the last 15 years we also express some concerns. Our main worry concerns the relinquishment of the simplicity requirement. Ever since the groundbreaking experiments of Galileo some three centuries ago, the great successes of physicists were largely due to the fact that they were able to decompose complex phenomena into simpler ones. Remember that the first observation of the effects of an electrical current was made by Alessandro Volta (1745-1827) on the leg of a frog! Clearly, to make sense this observation had to be broken down into several separate effects. Nowadays, with computers being able to handle huge amounts of data and to simulate any stochastic process no matter how complicated, there is no longer any real need for such a search for simplicity. Why should one spend time and effort trying to break up complicated phenomena when it is ...

To document various clinical presentations and management options of conjunctival squamous cell carcinoma (CSCC) in patients attending ophthalmic out patients department (OPD) of a tertiary care centre. This case series was carried out in the Department of Ophthalmology Civil Hospital and, Dow University of Health Sciences, Karachi and were reviewed from June 2004 to December 2007. Socio-demographic data and clinical features of patients with biopsy proven conjunctival squamous cell carcinoma were recorded and analysed. All patients underwent complete ophthalmic examination by a fellow ophthalmologist and clinical findings were recorded on a prescribed Performa. Data was analysed in terms of frequency, means and median by SPSS for windows V.15. Seventy-two percent of the patients were male and 28% were female, more than 80% of patients were in the age group of seventy years and above. Eighteen percent of patients developed intraocular invasion and the eyes had to be enucleated. CSCC occurs in sun damaged ocular surface usually at limbus, elderly men are more commonly involve, recurrence is a feature of disease and high risk in older individual. In our treatment we used various therapies, excision with clear margin, topical mitomycin C adjunctive cryotherapy and amniotic graft. (author)

The B0.5IVe star gam Cas is of great interest because it is the prototype of a small group of classical Be stars having hard X-ray emission of unknown origin. We discuss results from ongoing B and V observations of the gam Cas star-disk system acquired with an APT during the observing seasons 1997-2011. In an earlier study, Smith, Henry, & Vishniac showed that light variations in gam Cas are dominated by a series of comparatively prominent cycles with amplitudes of 0.02-0.03 mag and lengths of 2-3 months, superimposed on a 1.21-day periodic signal some five times smaller, which they attributed to rotation. The cycle lengths clustered around 70 days. Changes in both cycle length and amplitude were observed from year to year. These authors also found the V-band cycles to be 30-40% larger than the B-band cycles. In the present study we find continued evidence for these variability patterns and for the bimodal distribution of the B/V amplitude ratios in the long cycles. During the 2010 observing season, gam C...

Radiological protection experience in a regional radiopharmacy, currently handling 28.5 TBq (770 Ci) 99mTc y-1, is reviewed for the period 1974-1988. The results of personnel monitoring have shown a downward trend (by more than a factor of two) in radiation exposure of individual staff members, despite the workload per person [6000 GBq (162 Ci) 99mTc y-1] remaining virtually constant. Adequate staff selection and training contribute to the reduction in dose. A significant reduction in dose to the eyes was achieved by installing lead glass screens in the radiopharmacy work stations, and tungsten syringe shields reduced radiation dose to the hands. The use of commercially available kits for producing 99mTc radiopharmaceuticals, rather than relying on in-house preparations that require more operator handling, has also contributed to reduction in radiation exposure. Internal contamination of staff members with 125I was markedly reduced when the practice of sub-dispensing high-specific activity solutions of the radionuclide was discontinued. Annual doses from external radiation currently average less than 6 mSv (600 mrem) to the trunk, less than 7 mSv (700 mrem) to the eyes, and 50 mSv (5 rem) to the hands. Internal contamination of personnel with 125I, 131I, and 99mTc, as detected by thyroid and whole-body monitoring, contributed less than 65 mSv y-1 (6.5 rem) to the thyroid gland and less than 0.1 mSv y-1 (10 mrem) to the whole body
This work has been constituted around four questions: the future of the Chernobyl site, the damaged reactor, and the sarcophagus around it; the health consequences of the accident on the persons that have worked on the damaged reactor and on the population in the countries the most exposed to fallout,; the situation of contaminated territories around the power plant and their management today; the last question concerns especially the France with the consequences of the radioactive cloud and what we know about the health risks induced by this event.

Full Text Available Since beginning of 1990, several projects on biosafety research were initiated in Germany with genetically modified plants. Germany was also one of the first countries active on biosafety research with genetically modified trees (GMTs. An EU-funded project coordinated by the Institute of Forest Genetics (Johann Heinrich von Thuenen Institute, Grosshansdorf, from 1994 to 1997, was the first project of this kind in Germany. In the frame of this project, transgene stability was studied under greenhouse conditions in different transgenic aspen clones. A high degree of transgene expression stability was found in transgenic lines, however, gene silencing was detected in some transgenic plants. In Germany, the jump of the GMTs from the greenhouse to the field was initiated in 1996 by the Institute of Forest Genetics (Grosshansdorf, when the first field trial with genetically modified (GM poplar was approved for five years. In the year 2000 and in cooperation with the University of Tuebingen, the same institute established a second field trial with GM poplar to study possible horizontal gene transfer (HGT from the transgenic poplar into mycorrhizal fungi. No HGT was detected in those studies. Two further national funded projects on phytoremediation and status of mycorrhizal fungi in GMTs under field conditions were run by the University of Freiburg on 2002 - 2004 and 2003 - 2005. Topics of national funded biosafety research projects on GMTs released to the field but as well on greenhouse grown plants were transgene stability, genetic containment, transgene influence on mycorrhizal and phytopathogenic fungi, generative and vegetative propagation capacity, and horizontal gene transfer.

The aim of this study is to describe the occurrence of Hansen's disease in children under 15 years of age and to analyse the burden of disease in the same population in Brazil in 2011. This is a descriptive epidemiological study on the positive cases of Hansen's disease in minors below 15 years of age notified in Brazil. Data was collected from the Information System on Disease Notification for Hansen's disease cases, and the Brazilian Institute of Geographic Statistics for population data. The study's results showed that 2420 minors with Hansen's Disease in 2011 were distributed in 5565 cities, 692 cities registered the occurrence of 1-10 cases of the disease, a total of 1489 cases (61%); 35 cities showed 15 to 25 cases, 544 (22.5%); and eight cities notified 25 cases or more, totalling 87 cases (16%), therefore, about one third of the Hansen's disease cases in minors under 15 years in Brazil in the year of 2011 are concentrated in 43 Brazilian cities.

OBJECTIVE: Cervical collagen concentration decreases during pregnancy. The increased risk of preterm birth following a short interpregnancy interval may be explained by an incomplete remodeling of the cervix. The objective of this study was to describe the changes in cervical collagen concentration...... over 15 months following delivery. METHODS: The collagen concentrations were determined in cervical biopsies obtained from 15 women at 3, 6, 9, 12, and 15 months after delivery. RESULTS: The mean cervical collagen concentrations were 50, 59, 63, 65, and 65 % of dry weight (SD 4.2 – 6.5). This increase...... was statistically significant until month 9, but not between months 9 and 12. CONCLUSIONS: Low collagen concentrations in the uterine cervix may contribute to the association between a short interpregnancy interval and preterm birth....

More than 90% of the heat energy accumulation in the climate system between 1971 and the present has been in the ocean. Thus, the ocean plays a crucial role in determining the climate of the planet. Observing the oceans is problematic even under the most favourable of conditions. Historically, shipboard ocean sampling has left vast expanses, particularly in the Southern Ocean, unobserved for long periods of time. Within the past 15 years, with the advent of the global Argo array of profiling floats, it has become possible to sample the upper 2,000 m of the ocean globally and uniformly in space and time. The primary goal of Argo is to create a systematic global network of profiling floats that can be integrated with other elements of the Global Ocean Observing System. The network provides freely available temperature and salinity data from the upper 2,000 m of the ocean with global coverage. The data are available within 24 hours of collection for use in a broad range of applications that focus on examining climate-relevant variability on seasonal to decadal timescales, multidecadal climate change, improved initialization of coupled ocean-atmosphere climate models and constraining ocean analysis and forecasting systems.

How far do Media (Television, Video Games, Publications) influence the behavior of young people? The increasing occurrence of violent behavior (e.g. amuck shootings) suggest a negative influence upon the minds and behavior of youth. Psychologists point to the effects of propaganda, the fallacy of "behaviorism" and the facts of experience with addiction (e.g. pornography) and physical effects on the brain.

Full Text Available Christine A Cooper, Armon Jadidian, Michelle Paggi, Janet Romrell, Michael S Okun, et alDepartment of Neurology, University of Florida, Gainesville, FL, USAAbstract: This study investigates the prevalence and demographic characteristics of hypersexuality in Parkinson’s disease (PD. Impulse control disorders in PD patients have been associated with dopamine agonist therapy. Moreover, hypersexuality and pathological gambling have been associated with males, while females may be inherently thought to be more likely to participate in compulsive shopping and binge-eating behaviors. In this study, a screening mail-in survey was sent to all PD patients at a single Movement Disorders Center. One hundred forty one of 400 (35.3% research packets were returned completed. Fifteen of 141 patients met initial screening criteria for hypersexual behavior. After detailed interview, only 6/141 (4.3% of PD patients met criteria for pathologic hypersexual behavior. These behaviors included: compulsive masturbation, prostitution, and paraphilias. Patients with a younger age of PD onset were more likely to exhibit hypersexual behavior. Unlike previous report, no significant association was found between hypersexuality and gender or dopamine agonist use. Rather, this study suggests that physicians should be vigilant for hypersexual behavior in all PD patients, regardless of gender and PD medication regimen. Ultimately, given the innate sensitivity of the topic and survey limitations, it is very likely that hypersexual behavior in our cohort, as it is in the general PD population, has been under-reported.Keywords: Parkinson’s disease, hypersexuality, impulsive behavior, dopamine agonists
Full Text Available Anxiety is a special variety of fear, experienced in anticipation of threatening stimuli. While some research workers have said that the response of a child improves with the number of visits, many have felt otherwise. The present study is yet another effort to find the patterns of anxiety in children during sequential dental visits. The main aim was to determine the physiological and behavioral variations during sequential dental visits and its impact on age and sex. The study was conducted at the outpatient Department of Pedodontics and preventive dentistry, Meenakshi Ammal Dental College and Hospital, Chennai to evaluate the physiological and behavioural measures of stress and anxiety in children. One hundred and fifteen children, between four and eleven years of age who reported for dental treatment were selected for the study.

We present a model of behavioral dynamics that combines a social network-based opinion dynamics model with behavioral mapping. The behavioral component is discrete and history-dependent to represent situations in which an individual's behavior is initially driven by opinion and later constrained by physiological or psychological conditions that serve to maintain the behavior. Individuals are modeled as nodes in a social network connected by directed edges. Parameter sweeps illustrate model behavior and the effects of individual parameters and parameter interactions on model results. Mapping a continuous opinion variable into a discrete behavioral space induces clustering on directed networks. Clusters provide targets of opportunity for influencing the network state; however, the smaller the network the greater the stochasticity and potential variability in outcomes. This has implications both for behaviors that are influenced by close relationships verses those influenced by societal norms and for the effectiveness of strategies for influencing those behaviors.

Full Text Available Neo Classical economists used to posit that, since consumers are rational, they make decisions to maximize their pleasure (utility. Opposing to Neo Classical understanding, Behavioral Economists argue that, consumers are infect not rational, but prone to all sort of biases and habits that pull them being rational. For instance, there are too many irrational choices made by the Turkish consumers like; expensive wedding parties given by low income families; although riding bicycle is healthy and cheap, but people buy expensive cars; it is cheaper staying at a hotel or a timeshare, however people buy expensive summer houses, where they stayed only few weeks a year. These type of irrational behaviors adversely affect the decisions on savings, investments and economic growth. On the consumers irrationality, Tversky and Daniel Kahneman, winner of the 2002 Nobel Prize in Economics, wrote Prospect Theory. They developed a cognitive psychological model to explain divergences from neoclassical economics. They claimed that people take decisions under psychological, social, emotional and economic factors that affect market prices and resource allocation. In order to explain the irrational behaviors of Turkish consumers, I utilized some concepts such as conspicuous consumption (or keeping up with Johns, Veblen Effect, Bandwagon Effect, bounded rationality, 20 to 80 Law and ethical considerations developed by Behavioral Economists and Heterodox Economics. Thus, I came to conclusion that why the free market economic understanding fails in Turkey by giving some examples and economic reasons stated in the last section of this paper.

"Behavior which is effective only through the mediation of other persons has so many distinguishing dynamic and topographical properties that a special treatment is justified and indeed demanded" (Skinner, 1957, p. 2). Skinner's demand for a special treatment of verbal behavior can be extended within that field to domains such as music, poetry, drama, and the topic of this paper: mathematics. For centuries, mathematics has been of special concern to philosophers who have continually argued to the present day about what some deem its "special nature." Two interrelated principal questions have been: (1) Are the subjects of mathematical interest pre-existing in some transcendental realm and thus are "discovered" as one might discover a new planet; and (2) Why is mathematics so effective in the practices of science and engineering even though originally such mathematics was "pure" with applications neither contemplated or even desired? I argue that considering the actual practice of mathematics in its history and in the context of acquired verbal behavior one can address at least some of its apparent mysteries. To this end, I discuss some of the structural and functional features of mathematics including verbal operants, rule-and contingency-modulated behavior, relational frames, the shaping of abstraction, and the development of intuition. How is it possible to understand Nature by properly talking about it? Essentially, it is because nature taught us how to talk. PMID:25595115

Full Text Available Introduction Numerous studies have shown that sexual behavior increases among adolescents. Disharmony between biological and psychosocial maturity among young people may cause risky behavior, and endanger psychophysical and reproductive health of young persons. Material and methods A questionnaire on sexual behavior was completed by 169 adolescents, 1st and 4th year high school students. Results Every 6th first grade and every 2nd forth grade adolescent is sexually active. Male adolescents begin sexual activities significantly earlier (at the age of 15.6 than female adolescents (16.5. Also, young men have significantly more partners (3.6 than girls (1.3, and more parallel sexual relations than girls. Only 1/3 of sexually active adolescents always use some kind of contraception, more frequently boys (41.9% than girls (26.7%. Discussion Early commencement of sexual activity results with longer active period before realization of the reproductive function, which increases risk for reproductive health disorders. Unprotected sexual intercourse and large number of partners also present significant risk factors. Conclusion Sexual life of adolescents begins at the age of 16, on average, and only every third always uses contraceptive protection, which points to a need for better education on reproductive health by using contemporary methods. It is also necessary to increase availability of contraceptives (condoms at all places where adolescents spend time (in schools, bars, cinemas, disco clubs etc. in order to achieve responsible sexual behavior and protection of reproductive health among youth.

The dopamine system is a primary treatment target for cocaine dependence (CD), but research on dopaminergic abnormalities (eg, D2 receptor system deficiencies) has so far failed to translate into effective treatment strategies. The D3 receptor system has recently attracted considerable clinical interest, and D3 antagonism is now under investigation as a novel avenue for addiction treatment. The objective here was to evaluate the status and behavioral relevance of the D3 receptor system in CD, using the positron emission tomography (PET) radiotracer [11C]-(+)-PHNO. Fifteen CD subjects (many actively using, but all abstinent 7–240 days on scan day) and fifteen matched healthy control (HC) subjects completed two PET scans: one with [11C]-(+)-PHNO to assess D3 receptor binding (BPND; calculated regionally using the simplified reference tissue model), and for comparison, a second scan with [11C]raclopride to assess D2/3 binding. CD subjects also completed a behavioral battery to characterize the addiction behavioral phenotype. CD subjects showed higher [11C]-(+)-PHNO BPND than HC in the substantia nigra, which correlated with behavioral impulsiveness and risky decision making. In contrast, [11C]raclopride BPND was lower across the striatum in CD, consistent with previous literature in ⩾2 week abstinence. The data suggest that in contrast to a D2 deficiency, CD individuals may have heightened D3 receptor levels, which could contribute to addiction-relevant traits. D3 upregulation is emerging as a biomarker in preclinical models of addiction, and human PET studies of this receptor system can help guide novel pharmacological strategies for treatment.

Adolescence is a time of high-risk behavior and increased exploration. This developmental period is marked by a greater probability to initiate drug use and is associated with an increased risk to develop addiction and adulthood dependency and drug use at this time is associated with an increased risk. Human adolescents are predisposed toward an increased likelihood of risk-taking behaviors [Zuckerman M. Sensation seeking and the endogenous deficit theory of drug abuse. NIDA Res Monogr 1986;74:59-70.], including drug use or initiation. In the present study, adolescent animals were exposed to twenty days of either saline (0.9% sodium chloride), cocaine (20 mg/kg) or ethanol (1 g/kg) i.p. followed by a fifteen-day washout period. All animals were tested as adults on several behavioral measures including locomotor activity induced by a novel environment, time spent in the center of an open field, novelty preference and novel object exploration. Animals exposed to cocaine during adolescence and tested as adults exhibited a greater locomotor response in a novel environment, spent less time in the center of the novel open field and spent less time with a novel object, results that are indicative of a stress or anxiogenic response to novelty or a novel situation. Adolescent animals chronically administered ethanol and tested as adults, unlike cocaine-exposed were not different from controls in a novel environment, indicated by locomotor activity or time spent with a novel object. However, ethanol-exposed animals approached the novel object more, suggesting that exposure to ethanol during development may result in less-inhibited behaviors during adulthood. The differences in adult behavioral responses after drug exposure during adolescence are likely due to differences in the mechanisms of action of the drugs and subsequent reward and/or stress responsivity. Future studies are needed to determine the neural substrates of these long lasting drug-induced changes. PMID
AIM: Biological medicine is hard to fully and scientifically explain the etiological factor and pathogenesis of abnormal behaviors; while, researches on philosophy and psychology (including memetics) are beneficial to better understand and explain etiological factor and pathogenesis of abnormal behaviors. At present, the theory of philosophy and psychology is to investigate the entity of abnormal behavior based on the views of memetics.METHODS: Abnormal behavior was researched in this study based on three aspects, including instinctive behavior disorder, poorly social-adapted behavior disorder and mental or body disease associated behavior disorder. Most main viewpoints of memetics were derived from "The Meme Machine", which was written by Susan Blackmore. When questions about abnormal behaviors induced by mental and psychological diseases and conduct disorder of teenagers were discussed, some researching achievements which were summarized by authors previously were added in this study, such as aggressive behaviors, pathologically aggressive behaviors, etc.RESULTS: The abnormal behaviors mainly referred to a part of people's substandard behaviors which were not according with the realistic social environment, culture background and the pathologic behaviors resulted from people's various psychological diseases. According to the theory of "meme", it demonstrated that the relevant behavioral obstacles of various psychological diseases, for example, the unusual behavior of schizophrenia, were caused, because the old meme was destroyed thoroughly but the new meme was unable to establish; psychoneurosis and personality disorder were resulted in hard establishment of meme; the behavioral obstacles which were ill-adapted to society, for example, various additional and homosexual behaviors, were because of the selfish replications and imitations of "additional meme" and "homosexual meme"; various instinct behavioral and congenital intelligent obstacles were not significance

Nuclear reactor operator emergency response behavior has persisted as a training problem through lack of information. The industry needs an accurate definition of operator behavior in adverse stress conditions, and training methods which will produce the desired behavior. Newly assembled information from fifty years of research into human behavior in both high and low stress provides a more accurate definition of appropriate operator response, and supports training methods which will produce the needed control room behavior. The research indicates that operator response in emergencies is divided into two modes, conditioned behavior and knowledge based behavior. Methods which assure accurate conditioned behavior, and provide for the recovery of knowledge based behavior, are described in detail

While earlier approaches to religious thought and practice searched for 'magic bullet' approaches to explain religious thought and behavior, seeing it as an example of irrationality, illusion, integrative force, symbolism, or false explanations of origins, cognitive scientific approaches have suggested that we see it rather as an aggregate of the products of various cognitive mechanisms. Studies in the cognitive science of religion, informed by experimental work, have converged on a standard model of explaining religious thought and behavior by focussing on the role of minimally counter-intuitive concepts, agent and animacy detection, ritual representations, notions of contagion and contamination avoidance, theory of mind, coalitions, and moral intuitions.

In recent decades, pediatric medicine has undergone a shift in focus from infectious diseases to the effects of behavior on the health and development of children. At the same time, behavior analysts have increasingly evaluated the direct application of their technology to the development and maintenance of child health behavior. Unfortunately, applied behavior analysts have developed their technology parallel to, rather than collaboratively with, pediatricians and, as a result, are not recog...

Buyers sometimes exhibit seemingly “irrational” behavior with respect to prices and use socially embedded heuristics to simplify their purchase decisions. In some cases small changes in prices can lead to much larger than anticipated changes in sales and profitability. Sellers need to understand the heuristics consumers use, the situations in which they emerge, and recognize how they can respond in markets where information and knowledge of product attributes and competitive prices is increas...

Patients with REM sleep behavior disorder (RBD) enact violent dreams during REM sleep in the absence of normal muscle atonia. This disorder is highly frequent in patients with synucleinopathies (60%-100% of patients) and rare in patients with other neurodegenerative disorders. The disorder is detected by interview plus video and sleep monitoring. Abnormal movements expose the patients and bed partners to a high risk of injury and sleep disruption. The disorder is usually alleviated with melat...
Full Text Available Two behavioral models of memcapacitor are developed and implemented in SPICE-compatible simulators. Both models are related to the charge-controlled memcapacitor, the capacitance of which is controlled by the amount of electric charge conveyed through it. The first model starts from the state description of memcapacitor whereas the second one uses the memcapacitor constitutive relation as the only input data. Results of transient analyses clearly show the basic fingerprints of the memcapacitor.

This paper proposes and studies a theory of adaptive consumption behavior under income uncertainty and liquidity constraints. We assume that consumption is governed by a linear function of wealth, whose coefficients are revised each period by a procedure, which, although sophisticated, places few informational or computational demands on the consumer. We show that under a variety of settings, our procedure converges quickly to a set of coefficients with low welfare cost relative to a fully op...

Purpose - The purpose of this paper is to present the results of exploratory research designed to develop an awareness of healthcare behaviors, with a view toward improving the customer satisfaction with healthcare services. It examines the relationship between healthcare providers and their consumers/patients/clients. Design/methodology/approach - The study uses a critical incident methodology, with both effective and ineffective behavioral specimens examined across different provider groups. Findings - The effects of these different behaviors on what Berry (1999) identified as the common core values of service organizations are examined, as those values are required to build a lasting service relationship. Also examined are categories of healthcare practice based on the National Quality Strategy priorities. Research limitations/implications - The most obvious is the retrospective nature of the method used. How accurate are patient or consumer memories? Are they capable of making valid judgments of healthcare experiences (Berry and Bendapudi, 2003)? While an obvious limitation, such recollections are clearly important as they may be paramount in following the healthcare practitioners' instructions, loyalty for repeat business, making recommendations to others and the like. Further, studies have shown retrospective reports to be accurate and useful (Miller et al., 1997). Practical implications - With this information, healthcare educators should be in a better position to improve the training offered in their programs and practitioners to better serve their customers. Social implications - The findings would indicate that the human values of excellence, innovation, joy, respect and integrity play a significant role in building a strong service relationship between consumer and healthcare provider. Originality/value - Berry (1999) has argued that the overriding importance in building a lasting service business is human values. This exploratory study has shown how

Highlights: • We study the self-reported energy (electricity) curtailment behaviors of Greek households (N=285). • We find that the curtailment behaviors are distinct and should be studied/analyzed separately. • ‘Age’, ‘Gender’ and ‘Perceived Behavioral Control’ are statistically significant predictors of most behaviors. • The demographic/structural and the psychological predictors contribute significantly explain the variance of the behaviors. • The cluster of moral predictors does not contribute statistically significantly to the explained variance. - Abstract: This paper argues that electricity ‘curtailment’ behaviors (i.e. frequent and/or low cost or free energy saving behaviors) in households are distinct from one another and they thus should be analyzed and promoted. We test this claim with data from telephone interviews with Greek households in the capital city of Athens (N=285), analyzing the impact of a number of demographical/structural, psychological (based on the Theory of Planned Behavior) and moral (based on norms’ activation) predictors though hierarchical binary logistic regression modeling. We find that that each electricity curtailment behavior depends on a different mix of predictors with ‘Age’, ‘Gender’ and ‘Perceived Behavioral Control’ being statistically significant for most behaviors. Overall, the psychological and the demographical/structural clusters of variables substantially contribute to the explained variance of electricity curtailment behaviors. The moral cluster's contribution is not statistically significant since moral concerns are largely interwoven in the psychological constructs

Over the last ten to fifteen years, economists and legal scholars have become increasingly interested in and sensitive to behavioralist insights. In a companion article, Jon Hanson and Douglas Kysar argued that those scholars have nevertheless given short shrift to what is, at least for policymaking purposes, perhaps the most important lesson of the behavioralist research: individuals' perceptions and preferences are highly manipulable. According to Hanson and Kysar, one theoretical implication of that insight for products liability law is that manufacturers and marketers will manipulate the risk perceptions of consumers. Indeed, to survive in a competitive market, manufacturers and marketers must do so. In this Article, Hanson and Kysar present empirical evidence of market manipulation--a previously unrecognized source of market failure. The Article begins by surveying the extensive qualitative and quantitative marketing research and consumer behavioral studies that discern and influence consumer perceptions. It then provides evidence of market manipulation by reviewing common practices in everyday market settings, such as gas stations and supermarkets, and by examining familiar marketing approaches, such as environmentally oriented and fear-based advertising. Although consumers may be well-aware of those practices and approaches, they appear to be generally unaware of the extent to which those tactics are manipulative. The Article then focuses on the industry that has most depended upon market manipulation: the cigarette industry. Through decades of sophisticated marketing and public relations efforts, cigarette manufacturers have heightened consumer demand and lowered consumer risk perceptions. Because consumers are aware that smoking may pose significant health risks, the tobacco industry's success in manipulating risk perceptions constitutes especially strong evidence of the power of market manipulation. The Article concludes by arguing that the evidence of

Most temperament theories presume a biological basis to those behavioral tendencies thought to be temperamental in origin. Behavioral genetic methods can be used to test this assumption. Twin and adoption studies suggest that individual differences in infant and child temperament are genetically influenced. However, behavioral genetics has much more to offer to the study of temperament than simple heritability estimates. The present paper describes some recent findings from behavioral genetic...
The high growth rate of vehicle ownership and many novel drivers in China determine the special features of Chinese driver behavior. This thesis introduces a comparative study on driver behavior by the analysis of saturation flow at urban intersections, Driver Behavior Questionnaire surveys, focus group discussion, and in-car tests. The main characteristics of Chinese driver behavior have been identified. A new method is developed for a simulation model calibration based on the study results.
Abstract Traditional methods of discipline, like punishment, suspension, and expulsion have in the past seemed beneficial, on a short-term basis, against problem behavior in schools. Four schools in Norway have recently implemented Functional Behavior Assessment (FBA) as part of a pilot project, to test the School-Wide Positive Behavioral Support (SW-PBS). A completed FBA procedure reveals the setting events, the antecedents and the consequences around the problem behavior, which provides ...

The greatest intellectual challenge to the field of behavior analysis may be understanding linguistic productivity (e.g., being able to correctly say and understand novel sentences). One of the main issues concerning linguistic productivity is whether behavioral productivity is, itself, a fundamental behavioral process, as claimed by the proponents of relational frame theory, or whether we can understand linguistic productivity in terms of more fundamental behavioral principles.

A modification of the good behavior game was used to reduce disruptive behaviors during a weekly library period of children in a fourth-grade class. Modifications included student input in designing rules, attempts to state rules in positive terms, observation of class behavior in the experimental (library) setting as well as in a comparison (classroom) setting, and librarian involvement in instituting the game coupled with teacher involvement in delivering reinforcers. Reinforcers consisted of special classroom activities conducted by the teacher with winning team members. Modification of the good behavior game did not detract from its effectiveness in reducing disruptive and off-task behavior. PMID:16795642

Ecological theorists have suggested that "disturbance" may result from an interaction between a child's behavior and reactions to that behavior within ecosystems such as schools. In this context, behavior is viewed as "disturbing" rather than "disturbed" and equal emphasis is given to the child and to individuals with whom the child interacts when…

Full Text Available Self injury is a kind of behavior which begins in early adolescence and difficult to determine because remains suppressed. Most often forms are to cut and hit own. To be exposed to sexual abuse and stressfully life events are known as risk factors for self injurious behavior. High anxiety, depression and hostility levels, decrease of self esteem, suicidal attempts and thoughts are usually together with self injurious behavior and it may be mediating to emotional regulation. To explain the functions of self injurious behavior automatic and social support theories and social learning theories have suggested. The relation between suicidality and self injurious behavior is complex for adolescents. There is no enough knowledge if self injurious behavior aggravates the risk of completed suicide. Although it’s a frequent behavior there are limited randomized controlled studies which examine specific treatment approaches. Dialectic behavior treatment is the type of treatment which shown as most effective for adults. To determine the needs to stop the behavior, to manage emotional senses and urges and to learn more healthy ways for needs to youth are necessary in treatment of self injurious behavior. Treatment also includes determining suicidal risk and comorbid psychiatric disorders. In self injurious behavior medical treatment is useful for comorbid psychiatric disorders.

Background Young adults have the highest smoking rate of any age group in the U.S., and new strategies to decrease young adult smoking are needed. The objective of the current study was to identify psychographic and demographic factors associated with current smoking and quitting behaviors among young adults. Methods Attitudes, social groups, and self-descriptors, including supporting action against the tobacco industry, advertising receptivity, depression, alcohol use, and other factors associated with smoking were tested for associations with smoking behaviors in a 2005 cross-sectional survey of 1528 young adults (aged 18–25 years) from a web-enabled panel. Analyses were conducted in 2007. Results Being older was associated with current smoking, whereas having some higher education and being African American or Hispanic were negatively associated with smoking. Supporting action against the tobacco industry was negatively associated with smoking (AOR=0.34 [95% CI=0.22, 0.52]). Perceived usefulness of smoking, exposure to smokers, increased perceived smoking prevalence, receptivity to tobacco advertising, binge drinking, and exposure to tobacco advertising in bars and clubs were associated with smoking. Supporting action against the tobacco industry was associated with intentions to quit smoking (AOR= 4.43 [95% CI=2.18, 8.60]). Conclusions Young adults are vulnerable to tobacco-industry advertising. Media campaigns that denormalize the tobacco industry and appeal to young adults appear to be a powerful intervention to decrease young adult smoking. PMID:19269128

REM sleep is the stage associated with vivid dream mentation, desynchronous cortical EEG, and atonia of antigravitary muscles. REM sleep behavior disorder (RBD) is characterized by the intermittent loss of REM sleep atonia and by the appearance of elaborate motor activity associated with dream mentation. The animal model of REM sleep without atonia indicates that lesions to the perilocus coeruleus disrupt the excitatory connection to the nucleus reticularis magnocellularis in the descending medullary reticular formation and disable the hyperpolarization of the alpha spinal motoneurons. Extensive neurologic evaluations in humans suffering from both idiopathic and symptomatic forms have not identified specific lesions; however, findings in some patients suggest that diffuse lesions of the hemispheres, bilateral thalamic abnormalities, or primary brain-stem lesions may result in the RBD. Symptomatic RBD cases are associated with several neurologic disorders such as dementia, cerebrovascular diseases, multiple sclerosis, brain-stem neoplasm. RBD has been often documented to precede or to co-occur with neurodegenerative disorders, such as dementia, Parkinson's disease and multiple system atrophy. Most importantly, RBD is readily diagnosable and treatable. Patients and their bed partners usually report immediate improvement in sleep-related motor behavior with small doses of clonazepam.

This paper presents a formal symbolic language, with its own specialized vocabulary and grammar, for codifying any behavioral contingency, including the complex multiparty contingencies encountered in law, economics, business, public affairs, sociology, education, and psychotherapy. This language specifies the "if, then" and temporal relationships between acts and their consequences for the parties involved. It provides for the notation of the probabilities, magnitudes, positive or negative valences, or time delays of the consequences for the parties, and for the parties that would perceive, misperceive, not perceive, predict, mispredict, or not predict events. The language's fractal-like hierarchical and recursive grammar provides for the flexible combination and permutation of the modifiers of the language's four nouns: acts, consequences, time intervals, and agents of acts; and its four verbs: consequate, prevent, perceive, and predict-thereby giving the language the ability to describe and codify various nuances of such complex contingencies as fraud, betting, blackmail, various types of games, theft, crime and punishment, contracts, family dynamics, racing, competition, mutual deterrence, feuding, bargaining, deception, borrowing, insurance, elections, global warming, tipping for service, vigilance, sexual overtures, decision making, and mistaken identity. Applications to the management of practical situations and techniques for doing so, as well as applications in current behavior analysis research and neuroscience, are discussed. PMID:18329187
Full Text Available Challenging behavior in individuals with mental retardation (MR is relatively frequent, and represents a significant obstacle to adaptive skills. The frequency of specific forms and manifestations of challenging behavior can depend on a variety of personal and environmental factors. There are several prominent theoretical models regarding the etiology of challenging behavior and psychopathology in persons with MR: behavioral, developmental, socio-cultural and biological. The biological model emphasizes the physiological, biochemical and genetic factors as the potential source of challenging behavior. The progress in the field of genetics and neuroscience has opened the opportunity to study and discover the neurobiological basis of phenotypic characteristics. Genetic syndromes associated with MR can be followed by a specific set of problems and disorders which constitutes their behavioral phenotype. The aim of this paper was to present challenging behaviors that manifest in the most frequently studied syndromes: Down syndrome, Fragile X syndrome, Williams syndrome, Prader-Willi syndrome and Angelman syndrome. The concept of behavioral phenotype implies a higher probability of manifesting specific developmental characteristics and specific behaviors in individuals with a certain genetic syndrome. Although the specific set of (possible problems and disorders is distinctive for the described genetic syndromes, the connection between genetics and behavior should be viewed through probabilistic dimension. The probabilistic concept takes into consideration the possibility of intra-syndrome variability in the occurrence, intensity and time onset of behavioral characteristics, at which the higher variability the lower is the specificity of the genetic syndrome. Identifying the specific pattern of behavior can be most important for the process of early diagnosis and prognosis. In addition, having knowledge about behavioral phenotype can be a landmark in

We identified 15 randomized controlled trials of CBT for adults (aged 18 years and older that included suicide-related cognitions or behaviors as an outcome measure. The studies were identified from PsycINFO searches, reference lists, and a publicly available database of psychosocial interventions for suicidal behaviors. This review identified some evidence of the use of CBT in the reduction of both suicidal cognitions and behaviors. There was not enough evidence from clinical trials to suggest that CBT focusing on mental illness reduces suicidal cognitions and behaviors. On the other hand, CBT focusing on suicidal cognitions and behaviors was found to be effective. Given the current evidence, clinicians should be trained in CBT techniques focusing on suicidal cognitions and behaviors that are independent of the treatment of mental illness.

Long stigmatized, behavioral health conditions are finally becoming a focal point not just for policy makers but also in public discussions about the well-being of the United States. This is in part because of a rising opioid epidemic; the concentration of people with mental illnesses in prisons and jails; and a greater appreciation of the toll taken by depression and other mental disorders on individuals, families, and the economy. The United States spends more on mental health and addiction than on any other medical condition, including heart disease, trauma, and cancer. Within this spending, there's been a shift toward outpatient and other types of community treatment and away from inpatient care. Meanwhile, the Affordable Care Act has made it possible for more people with serious mental illnesses to obtain care, but treatment rates for racial and ethnic minorities still trail those of whites.

Current neurobiological research on temporal binding in binocular rivalry settings contributes to a better understanding of the neural correlate of perceptual consciousness. This research can easily be integrated into a theory of conscious behavior, but if it is meant to promote a naturalistic theory of perceptual consciousness itself, it is confronted with the notorious explanatory gap argument according to which any statement of psychophysical correlations (and their interpretation) leaves the phenomenal character of, e.g., states of perceptual consciousness open. It is argued that research on temporal binding plays no role in a naturalistic theory of consciousness if the gap argument can be solved on internal philosophical grounds or if it turns out to be unsolvable at the time being. But there may be a way to dissolve or deconstruct it, and the accessibility of this way may well depend on scientific progress, including neurobiological research on the neural correlate of perceptual consciousness.

The honeybee Apis mellifera (Apidae) is a model widely used in behavior because of its elaborate social life requiring coordinate actions among the members of the society. Within a colony, division of labor, the performance of tasks by different individuals, follows genetically determined physiological changes that go along with aging. Modern advances in tools of molecular biology and genomics, as well as the sequentiation of A. mellifera genome, have enabled a better understanding of honeybee behavior, in particular social behavior. Numerous studies show that aspects of worker behavior are genetically determined, including defensive, hygienic, reproductive and foraging behavior. For example, genetic diversity is associated with specialization to collect water, nectar and pollen. Also, control of worker reproduction is associated with genetic differences. In this paper, I review the methods and the main results from the study of the genetic and genomic basis of some behaviors in bees.

A large-scale, community-based survey was done to assess the frequency of a wide variety of sexual behaviors in normal preadolescent children and to measure the relationship of these behaviors to age, gender, and socioeconomic and family variables. A sample of 880 2- through 12-year-old children screened to exclude those with a history of sexual abuse were rated by their mothers using several questionnaire measures. The frequency of different behaviors varied widely, with more aggressive sexual behaviors and behaviors imitative of adults being rare. Older children (both boys and girls) were less sexual than younger children. Sexuality was found to be related to the level of general behavior problems, as measured by the Achenbach Internalizing and Externalizing T scores and to a measure of family nudity. It was not related to socioeconomic variables. PMID:1881723

Behavioral economics increases the explanatory power of economics by providing it with more realistic psychological foundations. This book consists of representative recent articles in behavioral economics. This chapter is intended to provide an introduction to the approach and methods of behavioral economics, and to some of its major findings, applications, and promising new directions. It also seeks to fill some unavoidable gaps in the chapters’ coverage of topics.
Self injury is a kind of behavior which begins in early adolescence and difficult to determine because remains suppressed. Most often forms are to cut and hit own. To be exposed to sexual abuse and stressfully life events are known as risk factors for self injurious behavior. High anxiety, depression and hostility levels, decrease of self esteem, suicidal attempts and thoughts are usually together with self injurious behavior and it may be mediating to emotional regulation. To explain the fun...
This paper offers a thoughtful discussion of social norms and alternative economic viewpoints and analysis of restaurant tipping behavior. A survey of Louisiana residents was conducted to collect public opinions about tipping. The analysis suggests that social norms are indeed the primary reason for diner tipping. As long as consumer behavior is guided by social norms, social norms will costs for diners. The conclusion suggests that if customer's tipping behavior were completely guided by soc...

This paper argues that economic rationality and ethical behavior cannot be reduced one to the other, casting doubts on the validity of formulas like 'profit is ethical' or 'ethics pays'. In order to express ethical dilemmas as opposing economic interest with ethical concerns, we propose a model of rational behavior that combines these two irreducible dimensions in an open but not arbitrary manner. Behaviors that are neither ethical nor profitable are considered irrational (...

Knowledge of the large and small momentum transfer behavior of the electron momentum distribution is an important ingredient in the analysis of experimental isotropic Compton profiles. This behavior ultimately rests upon the asymptotic behavior of atomic momentals (momentum space orbitals). The small momentum Maclaurin expansion and the large momentum asymptotic expansion of atomic momentals with arbitrary angular momentum quantum number are derived in this paper. Their implications for momentum densities and Compton profiles are derived and discussed.

The subject matter of this article is an analysis of the features of online buyer behavior compared to the general regularities of buyer behavior, definition of the main motives of online shopping, and description of the ...
In radical behaviorism, the difference between overt and covert responses does not depend on properties of the behavior but on the sensitivity of the measurement tools employed by the experimenter. Current neuroscientific research utilizes technologies that allow measurement of variables that are undetected by the tools typically used by behavior analysts. Data from a specific neuroscientific technique, event-related potential (ERP), suggest that emission of otherwise covert responses can be ...
This monograph describes and assesses the current state of behavioral law and economics. Law and economics had a critical (though underrecognized) early point of contact with behavioral economics through the foundational debate in both fields over the Coase theorem and the endowment effect. In law and economics today, both the endowment effect and other features of behavioral economics feature prominently and have been applied to many important legal questions.

Gonadotropin-inhibitory hormone (GnIH) is a hypothalamic neuropeptide that was isolated from the brains of Japanese quail in 2000, which inhibited luteinizing hormone release from the anterior pituitary gland. Here, we summarize the following fifteen years of researches that investigated on the mechanism of GnIH actions at molecular, cellular, morphological, physiological, and behavioral levels. The unique molecular structure of GnIH peptide is in its LPXRFamide (X=L or Q) motif at its C-terminal. The primary receptor for GnIH is GPR147. The cell signaling pathway triggered by GnIH is initiated by inhibiting adenylate cyclase and decreasing cAMP production in the target cell. GnIH neurons regulate not only gonadotropin synthesis and release in the pituitary, but also regulate various neurons in the brain, such as GnRH1, GnRH2, dopamine, POMC, NPY, orexin, MCH, CRH, oxytocin, and kisspeptin neurons. GnIH and GPR147 are also expressed in gonads and they may regulate steroidogenesis and germ cell maturation in an autocrine/paracrine manner. GnIH regulates reproductive development and activity. In female mammals, GnIH may regulate estrous or menstrual cycle. GnIH is also involved in the regulation of seasonal reproduction, but GnIH may finely tune reproductive activities in the breeding seasons. It is involved in stress responses not only in the brain but also in gonads. GnIH may inhibit male socio-sexual behavior by stimulating the activity of cytochrome P450 aromatase in the brain and stimulates feeding behavior by modulating the activities of hypothalamic and central amygdala neurons.

Full Text Available The recent years have witnessed a renewed interest in human sexual behavior, partly because of the growing AIDS pandemic. We undertook a study of the pattern of sexual behavior among outpatients attending our dermatology clinic. Sexually active patients attending the dermatology clinic for non-STD complaints from March 2007 to June 2007 were randomly selected and interviewed about their sexual behavior using a questionnaire. The study included 500 respondents (240 women, 260 men. The mean ages of the women and men were 37.9 years and 38.9 years, respectively. Forty-two of the unmarried men (54.5% were sexually active, while 55 of the married men (30% admitted to having had premarital sex. A total of 81 men (38.8% admitted to premarital sex, compared to only 2.9% of women. With regard to extramarital contact, 62 of the married men (33.8% were affirmative in their response, while the corresponding figure for married women was 12 (5.5%. Nine men had a history of bisexual contact and, of these, one man admitted to having had exclusively homosexual contact. Fifteen men had indulged in anal sex; 48.3% men with pre/extramarital contact had more than one partner, and 43 (30.1% had visited commercial sex workers (CSWs. Most of the respondents (141; 87% with pre/extramarital contact had had unsafe sex. Among the women with pre/extramarital sexual contact, most (17; 89.5% had only one partner; all were heterosexual and the majority had had sexual contact with relatives (73.7%. To summarize, men had overwhelmingly more pre/extramarital sexual contact as compared to women.

Full Text Available Behavior finance introduces psychology, sociology and other research methods into the study of investment behavior to explain how investors handle the information and take actions. This paper presents the literatures as theoretical solutions to the market anomalies of the traditional market theories. The behavioral psychology is examined through the study on the questionnaire of Chinese security investors. The results show that the investors are not always adopt rational behaviors as traditional finance theory assumed, but make a lot of irrational decisions based on individual cognitive and prejudices, even institutional investors often show the characteristic of irrational. In the guidance of the behavioral finance theory, the research will be closer to the reality and give more significant insight to the selection of investment strategy and psychology characteristic used to explain market anomalies.
An approach focusing on behavioral activation (BA) was adopted in the cognitive therapy of A. T. Beck, and it came to be considered that BA can play an important role in cognitive-behavioral therapy (CBT) for depression. Therefore, in recent years, BA based on clinical behavior analysis has been developed as a new treatment (Martell, et al.). The core characteristics are as follows: 1) focusing attention on context in daily life to promote the behavior control of patients and avoidance of a hatred experience ; 2) breaking the vicious circle; 3) promoting the behavior according to the purpose that the patients originally expect; 4) recognizing a relationship between behavior and the situation (contingency), thereby recovering self-efficacy tied to the long-term results that one originally expects. This does not increase pleasant activity at random when the patient is inactive, or give a sense of accomplishment. We know that depression is maintained by conducting functional analysis of detailed life behavior, and encourage the patients to have healthy behavior according to individual values. We help them to complete schedules regardless of mood and reflect on the results patiently. It is considered that those processes are important. BA may be easy to apply in clinical practice and effective for the chronic cases, or the patients in a convalescent stage. Also, in principle in the CBT for major depression, it may be effective that behavioral activation is provided in an early stage, and cognitive reconstruction in a latter stage. However, an approach to carry out functional analysis by small steps with careful activity monitoring is essential when the symptoms are severe. Furthermore, it should be considered that the way of psychoeducation requires caution because we encourage rest in the treatment of depression in our country. In particular, we must be careful not to take an attitude that an inactive behavior pattern is unproductive only based model cases. PMID
Recent developments affecting the mechanical behavior of superalloys over three ranges of operating temperatures are reviewed. At lower temperatures, activity has been focused on stress corrosion cracking susceptibility in light water reactor and sour gas well environments. The susceptibility to intergranular crack growth is critically dependent upon the grain boundary chemistry, and a method of minimizing the sensitivity of the boundaries to attack has been pursued. At intermediate temperatures, considerable effort has been directed toward increasing the tensile and fatigue strengths. The higher strength materials, however, show increased fracture sensitivity. In particular, embrittlement due to diffusion into the grain boundaries of aggressive species, such as oxygen or sulfur from the environments, becomes a problem. Minor element alloying additions of boron, zirconium, magnesium, etc., are helpful in retarding the degradation caused by the environment. At higher temperatures, the major thrust is toward improving the creep strength. The weak link in the materials, which is the transverse grain boundaries, has been eliminated by the use of specialized processing steps to produce either directionally solidified materials with minimum transverse grain boundaries, or single crystal materials. Single crystal materials permit alloying and heat treating modifications that further enhance the creep strength. The materials are very anisotropic in properties, but are successfully used in turbine blades and could be useful in other special applications

The article presents an analytical model to simulate experimental imperfections in the realization of an X-ray absorption spectroscopy experiment, performed in transmission or fluorescence mode. Distinction is made between sources of systematic errors on a time-scale basis, to select the more appropriate model for their handling. For short time-scale, statistical models are the most suited. For large time-scale, the model is developed for sample and beam imperfections: mainly sample inhomogeneity, sample self-absorption, beam achromaticity. The ability of this model to reproduce the effects of these imperfections is exemplified, and the model is validated on real samples. Various potential application fields of the model are then presented

Recently, it was pointed out that the non-Poisson statistics with heavy tail existed in many scenarios of human behaviors. But most of these studies claimed that power-law characterized diverse aspects of human mobility patterns. In this paper, we suggest that human behavior may not be driven by identical mechanisms and can be modeled as a Semi-Markov Modulated Process. To verify our suggestion and model, we analyzed a total of 1,619,934 records of library visitations (including undergraduate and graduate students). It is found that the distribution of visitation intervals is well fitted with three sections of lines instead of the traditional power law distribution in log-log scale. The results confirm that some human behaviors cannot be simply expressed as power law or any other simple functions. At the same time, we divided the data into groups and extracted period bursty events. Through careful analysis in different groups, we drew a conclusion that aggregate behavior might be composed of heterogeneous behaviors, and even the behaviors of the same type tended to be different in different period. The aggregate behavior is supposed to be formed by "heterogeneous groups". We performed a series of experiments. Simulation results showed that we just needed to set up two states Semi-Markov Modulated Process to construct proper representation of heterogeneous behavior.

The efficacy of non-pharmacological intervention for chronic insomnia has been proven by several meta-analytic reviews, an NIH report, an American Academy of Sleep Medicine review, and numerous clinical trials. Behavior therapy for chronic insomnia consists of relaxation, stimulus control, sleep restriction, cognitive restructuring and sleep hygiene education, which has produced reliable and durable changes in total sleep time, sleep onset latency, number and duration of awakening. These studies also showed that the post-treatment effect of behavior therapy is equal to that of hypnotic therapy, and that these effects were maintained for 6 months on follow-up assessment. Elderly insomniac patients would gain considerable benefit from behavioral treatments because there are no adverse physical effects as there are from pharmacological therapy. The authors present the basic theory, techniques of behavior therapy for insomnia, and the results of two important key meta-analytic reviews. Any behavioral approach such as convenient education, self-care enhancement by bibliotherapy, and individual face-to-face counseling, seem to be fruitful not only for American but also Japanese insomnia patients. Nonetheless, there are no currently actual intervention studies using behavior therapy in Japan. We have discussed the methodology of intervention study and published a behavioral self-help manual for people with sleep problems. Development of a behavioral approach to chronic insomnia seemed to be very beneficial and a useful contribution to mental health services. PMID:12373807

Aggression is a complex behavior that influences social relationships and can be seen as adaptive or maladaptive depending on the context and intensity of expression. A model organism suitable for genetic dissection of the underlying neural mechanisms of aggressive behavior is still needed. Zebrafish has already proven to be a powerful vertebrate model organism for the study of normal and pathological brain function. Despite the fact that zebrafish is a gregarious species that forms shoals, when allowed to interact in pairs, both males and females express aggressive behavior and establish dominance hierarchies. Here, we describe two protocols that can be used to quantify aggressive behavior in zebrafish, using two different paradigms: (1) staged fights between real opponents and (2) mirror-elicited fights. We also discuss the methodology for the behavior analysis, the expected results for both paradigms, and the advantages and disadvantages of each paradigm in face of the specific goals of the study.

Through refinements from research and judicious combination with other therapies, behavior therapy has become increasingly relevant in the treatment of psychiatric disorders. After outlining the four models that serve as a framework for behavior therapy (classical conditioning, operant conditioning, social learning theory, and cognitive behavior modification), the authors provide an update for clinicians on developments in the behavioral treatment of anxiety disorders, sexual disorders, depression, and schizophrenia. Most advances have been made in the treatment of anxiety disorders, including definition of variables for successful use of exposure to phobic stimuli in the treatment of phobic disorders and the use of flooding for post-traumatic stress disorder. By becoming better acquainted with cognitive and behavioral therapies, clinicians may be able to offer their patients more effective treatment options. PMID:2680882

In the context of agent based modeling and network theory, we focus on the problem of recovering micro behavior-related choice information from aggregate origin-destination data. As a basis for predicting agents' choices we emphasize the connection between adaptive intelligent behavior, causal entropy maximization and self-organized, equilibrium-seeking behavior in a dynamic system. We cast this problem in the form of a binary network and suggest information theoretic, entropy-driven methods to recover estimates of the unknown parameters connecting the behavioral data. Our objective is to recover the unknown behavioral binary parameters analytically, without explicitly sampling the configuration space. In order to do so, we enlarge the set of estimators commonly employed to make optimal use of the available information. More specifically, we consider the Cressie-Read family of entropic functionals and focus on three cases of particular interest. We then apply this information theoretic method to the analysis ...
Deformation of a crystal involves the motion of dislocations. Since dislocations interact, a short range and at long range, it is basic to understanding plasticity to establish if dislocations move singly or collectively. If deformation involves the collective motion of dislocations how does it manifest itself or equivalently how can it be measured? While a variety of techniques measure the positions of single dislocations before and after a stress is applied to a crystal, giving an average dislocation velocity, these techniques do not related directly to what happens during deformation, that is the collective behavior of dislocations. The mobile dislocation density is measured as follows: Lead-10% indium crystals are deformed at 4.2K, while in a magnetic field in the range Hc1 c2 where Hc1 is the lower critical field, H the applied field and Hc2 the upper critical field. During deformation changes n the flux are observed; the changes in flux are proportional to the mobile dislocation density. These changes in flux show the following characteristics: When the deformation process changes from elastic to plastic deformation there is a pronounced increase in flux noise, well above the background noise level. In addition superposed on this noise are pronounced bursts of magnetic flux, corresponding to dislocation bursts or avalanches of dislocations. A number of checks establish that these pulses are solely related to dislocations. These include the fact that they are not reproducible in terms of time from test to test, ruling out systematic instabilities in the circuit. Also, they occur when the crystal is unloaded and then reloaded at times, after plasticity is reinitiated, which are inconsistent with any time constant of the circuit. Finally, the measuring circuit shows no instabilities or ringing in this frequency range
Full Text Available Introduction : Neurological diseases are very important causes of prolonged morbidity and disability, leading to profound financial loss. Epilepsy is one of the most important neurological disorders Healthcare seeking by epilepsy patients is quite diverse and unique. Aims and Objectives: The study was conducted among the epilepsy patients, to assess their healthcare-seeking behavior and its determinants. Materials and Methods: Three hundred and fifteen epilepsy patients, selected by systematic random sampling, in the neuromedicine outpatient department of a tertiary care hospital were interviewed with a predesigned, pretested, semi-structured proforma. Results and Conclusion: More than 90% sought healthcare just after the onset of a seizure. The majority opted for allopathic medicine and the causes for not seeking initial care from allopaths were ignorance, faith in another system, constraint of money, and so on. A significant association existed between rural residence and low social status of the patients with initial care seeking from someone other than allopaths. No association was found among sex, type of seizure, educational status of the patients, and care seeking. The mean treatment gap was 2.98 ± 10.49 months and the chief motivators were mostly the family members. Patients for anti epileptic drugs preferred neurologists in urban areas and general practitioners in rural areas. District care model of epilepsy was proposed in the recommendation.

In this study, the fifteen-month behavior of two geosynthetic reinforced soil walls, which was constructed on the shallow weak ground, was measured and analyzed. The walls were backfilled with clayey soil obtained from the construction site nearby, and the safety factors obtained from general limit equilibrium analysis were less than 1.3 in both wall. To compare with the measured data from the real GRS walls and unreinforced soil mass, a series of finite element method (FEM) analyses on two field GRS walls and unreinforced soil mass were conducted. The FEM analysis results showed that failure plane of unreinforced soil mass was consistent with the Rankine active state, but failure plane did not occur in GRS walls. In addition, maximum horizontal displacements and shear strains in GRS walls were 50% smaller than those found in unreinforced soil mass. Modeling results such as the maximum horizontal displacements, horizontal pressure, and geosynthetic tensile strengths in GRS wall have a god agreement with the measured data. Based on this study, it could be concluded that geosynthetic reinforcement are effective to reduce the displacement of the wall face and/or the deformation of the backfill soil even if the mobilized tensile stress after construction is very small.
Studies on the development of eating behavior in rural India indicated that mothers of young children made food choices that fit into their budgets, and were also influenced by new information. Their choices were still immersed in traditional beliefs, some of which had positive effects on nutrition. Specific childrearing behaviors influenced positive deviance in the growth and psychosocial development of infants and preschoolers. A life-cycle approach to the development of eating behavior that deciphers needs at each stage and linkages between stages is necessary. Cost-benefit needs to be considered when devising strategies for future intervention programs. PMID:12035868
Background Children are 5 times more likely to be overweight at the age of 12 years if they are overweight during the preschool period. Objective The purpose of this study was to establish the feasibility, acceptability, and preliminary effects of a cognitive behavioral intervention (TEXT2COPE) synergized with tailored mobile technology (mHealth) on the healthy lifestyle behaviors of parents of overweight and obese preschoolers delivered in a primary care setting. Methods Fifteen preschooler-parent dyads recruited through primary care clinics completed a manualized 7-week cognitive behavioral skills building intervention. Beck’s Cognitive Theory guided the TEXT2COPE intervention content and Fogg’s Behavior Model guided the implementation. The intervention employed a combination of face-to-face clinic visits and ecological momentary interventions using text messaging (short message service, SMS). To enhance the intervention’s relevance to the family’s needs, parents dictated the wording of the text messages and also were able to adapt the frequency and timing of delivery throughout program implementation. Results Self-reported findings indicate that the program is feasible and acceptable in this population. The intervention showed preliminary effects with significant improvements on parental knowledge about nutrition (P=.001) and physical activity (P=.012) for their children, parental beliefs (P=.001) toward healthy lifestyles, and parental behaviors (P=.040) toward engaging in healthy lifestyle choices for their children. Effect sizes were medium to large for all variables. The timing, frequency, and wording of the text messages were tailored to the individual families, with 69% of parents (9/13) increasing the frequency of the tailored SMS from being sent once weekly to as many as 5 times a week. Conclusions Utilizing a cognitive behavioral skills intervention with SMS has great potential for supporting clinical care of overweight and obese preschool
From the viewpoint of teleological behaviorism the first question to ask in attempting to understand any behavior, including violent behavior, is: What are its contingencies of reward and punishment? Or, to put the question in economic terms: What are the short-term and long-term costs and benefits that such behavior entails? Let us therefore consider the costs and benefits of youth violence. Among the short-term costs of violent behavior are the physical effort of the act, the possibility of immediate physical retaliation, immediate social disapproval, and the opportunity cost of other social acts that the violent behavior takes the place of (you can't be affectionate and violent at the same time, for instance). Among the immediate benefits of violent behavior are the intrinsic satisfaction of the violent act itself and any extrinsic benefit; if A violently appropriates B's new sneakers then obtaining the sneakers reinforces A's violence. These immediate benefits may well outweigh the costs in many contexts. Among the long-term costs of violent behavior are delayed retaliation, possible social disapproval and loss of social support, rejection from a social group, job loss, and health risks associated with a violent lifestyle. Among the long-term benefits are long-term intimidation of others (your neighbor is less likely to build a fence on your property if you have a reputation for violence), and a possibly exciting lifestyle. These long-term benefits may well be outweighed by the long-term costs. Opposition of long-term net costs to short-term net benefits, where it exists, creates a personal self-control trap: Overall satisfaction may decrease monotonically with rate of the target behavior but, regardless of its rate, the immediate satisfaction of doing it is always higher than that of not doing it. In the case of violent behavior, this trap is exacerbated by the fact that as a person's violence increases, net immediate reinforcement also increases (due to

Compulsive buying behavior (CBB) has been recognized as a prevalent mental health disorder, yet its categorization into classification systems remains unsettled. The objective of this study was to assess the sociodemographic and clinic variables related to the CBB phenotype compared to other behavioral addictions. Three thousand three hundred and twenty four treatment-seeking patients were classified in five groups: CBB, sexual addiction, Internet gaming disorder, Internet addiction, and gambling disorder. CBB was characterized by a higher proportion of women, higher levels of psychopathology, and higher levels in the personality traits of novelty seeking, harm avoidance, reward dependence, persistence, and cooperativeness compared to other behavioral addictions. Results outline the heterogeneity in the clinical profiles of patients diagnosed with different behavioral addiction subtypes and shed new light on the primary mechanisms of CBB. PMID:27378999

We propose Behavior Engineering as a new technological area whose aim is to provide methodologies and tools for developing autonomous robots. Building robots is a very complex engineering enterprise that requires the exact definition and scheduling of the activities which a designer, or a team of designers, should follow. Behavior Engineering is, within the autonomous robotics realm, the equivalent of more established disciplines like Software Engineering and Knowledge Engineering. In this article we first give a detailed presentation of a Behavior Engineering methodology, which we call Behavior Analysis and Training (BAT), where we stress the role of learning and training. Then we illustrate the application of the BAT methodology to three cases involving different robots: two mobile robots and a manipulator. Results show the feasibility of the proposed approach.

Sickness behavior is a motivational state that redirects the needs and priorities of the organism during infection to aid recovery. The behavioral changes include fatigue, lowered mood and aches. Peripheral cytokines signal to the brain via autonomic nerves and the bloodbrain interface and change the inflammatory status of the brain, a mechanism that in recent years has been implied in complex syndromes like long-term pain, depression, fatigue and overall poor well-being.

Much of economic theory is built on observations of aggregate, rather than individual, behavior. Here, we present novel findings on human shopping patterns at the resolution of a single purchase. Our results suggest that much of our seemingly elective activity is actually driven by simple routines. While the interleaving of shopping events creates randomness at the small scale, on the whole consumer behavior is largely predictable. We also examine income-dependent differences in how people shop, and find that wealthy individuals are more likely to bundle shopping trips. These results validate previous work on mobility from cell phone data, while describing the unpredictability of behavior at higher resolution.
With the development of middleware technology, there are some new features to be adopted on demand in middleware platform based on container component. Aiming at the adaptation of middleware platform, from the nature of component container, this paper begins with behaviors features of EJB (Enterprise Java Bean) container, extracts general behaviors protocol of container, and defines its formal behaviors specification. In the end, the interactive relationship of components is described by WRIGHT language, and the configuration of whole system is shown. The method proposed in this paper mines the hidden features of framework of component container, and applies to refactor middleware platform in reflection and aspect-oriented programming technology.

Full Text Available The insulin signaling pathway has been hypothesized to play a key role in regulation of worker social insect behavior. We tested whether insulin treatment has direct effects on worker honeybee behavior in two contexts, sucrose response thresholds in winter bees and the progression to foraging by summer nurse bees. Treatment of winter worker bees with bovine insulin, used as a proxy for honeybee insulin, increased the bees’ sucrose response threshold. Treatment of summer nurse bees with bovine insulin significantly decreased the age at which foraging was initiated. This work provides further insight into the role of endocrine controls in behavior of in honeybees and insects in general.

Full Text Available The contribution of many scientific disciplines allows us to know surprising aspects of the relationship between the brain and its functions. Current technology and the convergence of these disciplines are essential to understand the complex brain mechanisms underlying behavior. In this paper will be described some scientific disciplines whose studies help to understand the biological substrates of normal and altered behavior. We will describe some pathologies or neuropsychological disorders and, in addition, we will review some of the known neurobiological mechanisms that control our brain functions. This allows us to conclude that the behavior and brain functions depend on complex biological mechanisms, many of which are still to be elucidated.

Direct behavior rating (DBR) offers users a flexible, feasible method for the collection of behavioral data. Previous research has supported the validity of using DBR to rate three target behaviors: academic engagement, disruptive behavior, and compliance. However, the effect of the base rate of behavior on rater accuracy has not been established.…

Full Text Available Much of the existing literature on financial behavior focuses on basic money management tasks (e.g., balancing a checkbook. However, it can be equally important to identify problematic financial behaviors that can sabotage one’s financial health. The purpose of this study was to create an assessment tool that can be used by mental health and financial professionals to identify disordered money behaviors that may impede on progress towards one’s financial goals. This study asked 422 respondents to indicate their agreement with disordered money behaviors, including compulsive buying, pathological gambling, compulsive hoarding, workaholism, financial enabling, financial dependence, financial denial, and financial enmeshment, which were correlated with demographic characteristics and financial outcomes. The results identified eight subscales derived from 68 disordered money behavior items. All eight subscales were found to have high reliability in measuring disordered behaviors, and six were associated with negative financial health indicators (e.g. less net worth, less income, and/or more revolving credit.

McDowell's evolutionary theory of behavior dynamics (McDowell, 2004) instantiates populations of behaviors (abstractly represented by integers) that evolve under the selection pressure of the environment in the form of positive reinforcement. Each generation gives rise to the next via low-level Darwinian processes of selection, recombination, and mutation. The emergent patterns can be analyzed and compared to those produced by biological organisms. The purpose of this project was to explore the effects of high mutation rates on behavioral variability in environments that arranged different reinforcer rates and magnitudes. Behavioral variability increased with the rate of mutation. High reinforcer rates and magnitudes reduced these effects; low reinforcer rates and magnitudes augmented them. These results are in agreement with live-organism research on behavioral variability. Various combinations of mutation rates, reinforcer rates, and reinforcer magnitudes produced similar high-level outcomes (equifinality). These findings suggest that the independent variables that describe an experimental condition interact; that is, they do not influence behavior independently. These conclusions have implications for the interpretation of high levels of variability, mathematical undermatching, and the matching theory. The last part of the discussion centers on a potential biological counterpart for the rate of mutation, namely spontaneous fluctuations in the brain's default mode network. PMID:27002687

Acquisition of resources and opportunity to engage in natural behaviors has been shown to reduce frustration-related behaviors and enhance health in nondomestic felids kept in zoos, but little is known about whether there are similar effects in domestic cats living in confinement in animal shelters. Fifteen cats rated as Frustrated during the first hour of confinement to a cage at an animal shelter were assigned to either a Treatment (n=7) or Control (n=8) group. Treatment cats were taken from their cages to a separate room four times daily for 10min each time over a 10 d period, where they took part in training sessions to learn a novel behavior (paw-hand contact with a researcher). Changes in emotional states and mucosal immune response were evaluated over 10days. Infectious status was determined upon admission and incidence of upper respiratory was determined up to day 40 based on clinical signs. Treated cats were more likely to be rated as Content than Control cats and had greater concentrations of S-IgA (537μg/g) in feces than Control cats (101μg/g). Within the Treatment group, cats that responded positively had greater concentrations of S-IgA (925μg/g) than those that responded negatively (399μg/g). Control cats were more likely to develop respiratory disease over time compared to cats that received treatment (Hazard Ratio: 2.37, Confidence Interval: 1.35-4.15). It is concluded that there is prima facie evidence that cognitive enrichment of cats exhibiting frustration-related behaviors can elicit positive affect (contentment), stimulate secretion of IgA and reduce incidence of respiratory disease, which is worthy of further study.

Stalking is a complex behavioral phenomenon that is unique in that it necessarily involves a prolonged dyadic relationship between both a perpetrator and a victim. Since criminalization of stalking behavior in the 1990s, different conceptual typologies have attempted to classify this behavior to assess risk and aid in management decisions. The authors reviewed the current literature regarding the most recent and accepted stalking classification systems. The three predominant stalker typologies currently in use include Zona's stalker-victim types, Mullen's stalker typology, and the RECON stalker typology. Of these, the RECON classification system alone was developed in an attempt to separate stalkers into groups based on previously known risk factors for behaviorally based phenomenon such as propensity for violence. Understanding and simplifying these classification systems may enhance the potential that new research will lead to evidence-based management and treatment strategies in the stalking situation.

Full Text Available Today, obesity is a public health problem with significant negative effects on mortality and morbidity rates in developing countries, and impact on all levels of the society. In recent years cognitive behavioral therapy approach has been considered as an important part of the obesity treatment. Behavioral therapy for obesity includes sections like self-monitoring, stimulus control, food control, consolidation and reinforcement, cognitive restructuring, proper nutrition education, increase in physical activity, and behavior contracts. As part of the obesity treatment, combining cognitive-behavioral treatments with lifestyle changes such as increase in physical activity increases effectiveness of the treatment and ensures durability of the achieved weight loss.

Full Text Available Introduction: Health status and health-related quality of life of postmenopausal women are issues, which nowadays pose a serious challenge to many domains of science. Climacteric symptoms which occur at this stage of life, lower its quality and make a negative contribution to self-reported health status, are mostly observed in a particular group of women. Evaluation of health behaviors performed using a standardized questionnaire, the Health Behavior Inventory (HBI, may help establish a comprehensive diagnosis of women’s health, and thus select effective interventions. A systemic approach to menopause assumes that full fitness of women and good quality of their lives can be maintained not only by means of pharmacotherapy but also other forms of action, especially health education oriented towards changes in the lifestyle and promotion of healthy behaviors. The aim of this study is to perform a HBI-based assessment of women’s health behaviors in such categories as healthy eating habits (HEH, preventive behaviors (PB, positive mental attitudes (PMA, and health practices (HP. Material and methods: The study involved 151 healthy postmenopausal women. A research tool was a standardized questionnaire, the Health Behavior Inventory (HBI. Results: The surveyed women obtained 70% of the maximum score on average, which suggests a medium level of health behaviors in this group. The levels of health behaviors in the categories of positive mental attitudes and health practices significantly differed between older women and their younger counterparts (higher levels were observed among older respondents. There were also significant differences in the levels of healthy behaviors between women with secondary and higher education (those better educated declared healthy behaviors more often. There was no correlation between the level of health behaviors and the BMI of the surveyed women. Conclusions : Older women attached greater

Binary logit and bivariate probit models were used to investigate the investment behavior of farmers relative to two energy-conserving assets, heat-recovery systems and precoolers. The bivariate probit procedure was useful in correcting for self-selectivity bias. Holdout samples and cross-validation procedures were used to develop true model statistics. Farm size, educational level of the operator, and the type of milking system in use were the important factors influencing investment behavior.

There exist two ways to obtain walk behavior: assuming a large number of technifermions in the fundamental representation of the technicolor (TC) gauge group, or a small number of technifermions, assuming that these fermions are in higher-dimensional representations of the TC group. We propose a scheme to obtain the walking behavior based on technicolored GUTs (TGUTs), where elementary scalars with the TC degree of freedom may remain in the theory after the GUT symmetry breaking.

The subjects were 25 foremen, 5 general foremen, and the production manager of a manufacturing plant. Each supervisor described the leader behavior of his immediate superior, and each in turn was described by several subordinates. Both superiors and the subordinates of a supervisor rated or described the productivity, morale, and cohesiveness of the group that he supervised. Thirty variables were intercorrelated and factor analyzed. The resulting 14 factors describe dimensions of employee satisfaction, supervisory behavior and status, and group performance. PMID:26753678

This paper reviews recent research on the nature of flow and transport in discontinuous fracture networks. The hydrologic behavior of these networks has been examined using two- and three-dimensional numerical models. The numerical models represent random realizations of fracture networks based on statistical field measurements of fracture geometry and equivalent hydraulic aperture. We have compared the flux and mechanical transport behavior of these networks to the behavior of equivalent continua. In this way we are able to determine whether a given fracture network can be modeled as an equivalent porous media in both flux and advective transport studies. We have examined departures from porous media behavior both as a function of interconnectivity and heterogeneity. Parameter studies have revealed behavior patterns such as: given a fracture frequency that can be measured in the field, porous media like behavior and the magnitude of permeability are both enhanced if the fractures are longer and the standard deviation of fracture permeabilities is smaller. Transport studies have shown that the ratio between flux and velocity is not necessarily constant when the direction of flow is changed in systems which do behave like a porous media for flux. Thus the conditions under which porous media analysis can be used in transport studies are more restrictive than the condition for flux studies. We have examined systems which do not behave like porous media and have shown how the in situ behavior varies as a function of scale of observation. The behavior of well tests in fractured networks has been modeled and compared to a new analytical well test solution which accounts for the early time dominance of the fractures intersecting the well. Finally, a three-dimensional fracture flow model has been constructed which assumes fractures are randomly located discs. 13 references, 12 figures

The rationality assumption that underlies mainstream economic theory has proved to be a useful approximation, despite the fact that systematic violations to its predictions can be found. That is, the assumption of rational behavior is useful in understanding the ways in which many successful economic institutions function, although it is also true that actual human behavior falls systematically short of perfect rationality. We consider a possible explanation of this apparent inconsistency, su...

Automatic behaviors are those that occur without awareness, are initiated without intention, tend to continue without contr...

Environmental toxicology is too permeated by questions about how the whole organism functions to abandon intact animals as test systems. Behavior does not participate as a single entity or discipline. It ranges across the total spectrum of functional toxicity, from tenuous subjective complaints to subtle sensory and motor disturbances demanding advanced instrumentation for their evaluation. Three facets of behavioral toxicology that illustrate its breadth of interests and potential contributions are discussed.

Empathy shapes the landscape of our social lives. It motivates prosocial and caregiving behaviors, plays a role in inhibiting aggression, and facilitates cooperation between members of a similar social group. Thus, empathy is often conceived as a driving motivation of moral behavior and justice, and as such, everyone would think that it should be cultivated. However, the relationships between empathy, morality, and justice are complex. We begin by explaining what the notion of empathy encompa...

Full Text Available Abstract The Relapse Prevention (RP model has been a mainstay of addictions theory and treatment since its introduction three decades ago. This paper provides an overview and update of RP for addictive behaviors with a focus on developments over the last decade (2000-2010. Major treatment outcome studies and meta-analyses are summarized, as are selected empirical findings relevant to the tenets of the RP model. Notable advances in RP in the last decade include the introduction of a reformulated cognitive-behavioral model of relapse, the application of advanced statistical methods to model relapse in large randomized trials, and the development of mindfulness-based relapse prevention. We also review the emergent literature on genetic correlates of relapse following pharmacological and behavioral treatments. The continued influence of RP is evidenced by its integration in most cognitive-behavioral substance use interventions. However, the tendency to subsume RP within other treatment modalities has posed a barrier to systematic evaluation of the RP model. Overall, RP remains an influential cognitive-behavioral framework that can inform both theoretical and clinical approaches to understanding and facilitating behavior change.

Behavioral targeting is an online marketing method that collects data on the browsing activities of consumers, in order to `target' more relevant online advertising. Behavioral targeting enables marketers to reach in-market consumers and increases the value of publisher inventory. At the heart of behavioral targeting is a learning-based investigation of consumer behaviors. It helps marketers understand consumers' purchase patterns over time, mapping out a customer's activities based not only on a single purchase but also on an annual or even lifetime basis. As marketers increasingly appreciate the importance of customer lifetime value, behavioral targeting can be a foundation for creating a continuous analytical study of consumer trends and patterns. But as behavioural-targeting systems become more sophisticated and invasive, it is vital that the companies behind them are open with users about what is going on, and give them control over their personal information. The aim of this paper is to explore the various tools and techniques of behavioral targeting and its benefits to online marketing. A multiple—case study approach was used for exploring the effectiveness and acceptance of online marketing in the area of the online marketing.

Editors play a critical role in the peer review system. How do editorial behaviors affect the performance of peer review? No quantitative model to date allows us to measure the influence of editorial behaviors on different peer review stages such as, manuscript distribution and final decision making. Here, we propose an agent-based model in which the process of peer review is guided mainly by the social interactions among three kinds of agents representing authors, editors and reviewers respectively. We apply this model to analyze a number of editorial behaviors such as decision strategy, number of reviewers and editorial bias on peer review. We find out that peer review outcomes are significantly sensitive to different editorial behaviors. With a small fraction (10 %) of biased editors, the quality of accepted papers declines 11 %, which indicates that effects of editorial biased behavior is worse than that of biased reviewers (7 %). While several peer review models exist, this is the first account for the study of editorial behaviors that is validated on the basis of simulation analysis. PMID:27386349

Full Text Available Abstract. There are numerous problems with the hypothesis that brain dopamine (DA systems, particularly in the nucleus accumbens, directly mediate the rewarding or primary motivational characteristics of natural stimuli such as food. Research and theory related to the functions of mesolimbic DA are undergoing a substantial conceptual restructuring, with the traditional emphasis on hedonia and primary reward yielding to other concepts and lines of inquiry. The present review is focused upon the involvement of nucleus accumbens DA in behavioral activation and effort-related processes. Viewed from the framework of behavioral economics, the effects of accumbens DA depletions and antagonism on food-reinforced behavior are highly dependent upon the work requirements of the instrumental task, and DA depleted rats are more sensitive to increases in response costs (i.e., ratio requirements. Moreover, interference with accumbens DA transmission exerts a powerful influence over effort-related choice behavior. Rats with accumbens DA depletions or antagonism reallocate their instrumental behavior away from food-reinforced tasks that have high response requirements, and instead these rats select a less-effortful type of food-seeking behavior. Nucleus accumbens DA and adenosine interact in the regulation of effort-related functions, and other brain structures (anterior cingulate cortex, amygdala, ventral pallidum also are involved. Studies of the brain systems regulating effort-based processes may have implications for understanding drug abuse, as well as energy-related disorders such as psychomotor slowing, fatigue or anergia in depression and other neurological disorders.

During an infection, animals suffer several changes in their normal physiology and behavior which may include lethargy, appetite loss, and reduction in grooming and general movements. This set of alterations is known as sickness behavior and although it has been extensively believed to be orchestrated primarily by the immune system, a relevant role for the central nervous system has also been established. The aim of the present work is to develop a simple animal model to allow studying how the immune and the nervous systems interact coordinately during an infection. We administered a bacterial lipopolysaccharide (LPS) into the thorax of honey bees to mimic a bacterial infection, and then we evaluated a set of stereotyped behaviors of the animals that might be indicative of sickness behavior. First, we show that this immune challenge reduces the locomotor activity of the animals in a narrow time window after LPS injection. Furthermore, bees exhibit a loss of appetite 60 and 90 min after injection, but not 15 h later. We also demonstrate that LPS injection reduces spontaneous antennal movements in harnessed animals, which suggests a reduction in the motivational state of the bees. Finally, we show that the LPS injection diminishes the interaction between animals, a crucial behavior in social insects. To our knowledge these results represent the first systematic description of sickness behavior in honey bees and provide important groundwork for the study of the interaction between the immune and the neural systems in an insect model.

The success of a project is dependent in part on the skills, knowledge, and behavior of its leader, the project manager. Despite advances in project manager certifications and professional development, the aerospace and defense industry has continued to see highly visible and expensive project failures partially attributable to failures in leadership. Servant leadership is an emerging leadership theory whose practitioners embrace empowerment, authenticity, humility, accountability, forgiveness, courage, standing back, and stewardship, but has not yet been fully examined in the context of the project manager as leader. The objective of this study was to examine the relationship between servant leadership behaviors demonstrated by aerospace and defense project managers and the resulting success of their projects. Study participants were drawn from aerospace and defense oriented affinity groups from the LinkedInRTM social media web system. The participants rated their project managers using a 30-item servant leadership scale, and rated the success of their project using a 12-item project success scale. One hundred and fifteen valid responses were analyzed from 231 collected samples from persons who had worked for a project manager on an aerospace and defense project within the past year. The results of the study demonstrated statistically significant levels of positive correlation to project success for all eight servant leadership factors independently evaluated. Using multiple linear regression methods, the servant leadership factors of empowerment and authenticity were determined to be substantial and statistically significant predictors of project success. The study results established the potential application of servant leadership as a valid approach for improving outcomes of projects.
Full Text Available Suicidal behavior constitutes a major public health problem. Based on the stress–diathesis model, biological correlates of a diathesis might help to predict risk after stressor-exposure. Structural changes in cortical and subcortical areas and their connections have increasingly been linked with the diathesis. The current study identified structural network changes associated with a diathesis using a whole-brain approach by examining the structural connectivity between regions in euthymic suicide attempters. In addition, the association between connectivity measures, clinical and genetic characteristics was investigated. We hypothesized that suicide attempters showed lower connectivity strength, associated with an increased severity of general clinical characteristics and an elevated expression of short alleles in serotonin polymorphisms.Thirteen euthymic suicide attempters (SA were compared with fifteen euthymic non-attempters and seventeen healthy controls. Clinical characteristics and three serotonin-related genetic polymorphisms were assessed. Diffusion MRI together with anatomical scans were administered. Preprocessing was performed using Explore DTI. Whole brain tractography of the diffusion-weighted images was followed by a number of streamlines-weighted network analysis using NBS.The network analysis revealed decreased connectivity strength in SA in the connections between the left olfactory cortex and left anterior cingulate gyrus. Furthermore, SA had increased suicidal ideation, hopelessness and self-reported depression, but did not show any differences for the genetic polymorphisms. Finally, lower connectivity strength between the right calcarine fissure and the left middle occipital gyrus was associated with increased trait anxiety severity (rs=-0.78, p<0.01 and hopelessness (rs=-0.76, p<0.01.SA showed differences in white matter network connectivity strength associated with clinical characteristics. Together, these variables could

Early antisocial behavior has its origins in childhood behavior problems, particularly those characterized by aggressive and destructive behavior. Deficits in self-regulation across multiple domains of functioning, from the physiological to the cognitive, are associated with early behavior problems, and may place children at greater risk for the development of later antisocial behavior. Data are presented from a longitudinal study of early self-regulation and behavior problems, the RIGHT Trac...

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding fo...

The purpose of this study is to assess whether different sexual risk behavior exists among young Black men who have sex with men (YBMSM) as a function of age. A total of 382 YBMSM completed a computer-assisted self-interview at a sexual health clinic. The frequency/prevalence of fifteen sexual risk behaviors was compared between three groups (ages 16-19, 20-25, and 26-29, respectively) in the 90 days prior to enrollment in the study. Regression models were used to control for the confounding influence of Human Immunodeficiency Virus (HIV) status. One hundred seven participants were HIV-infected at study enrollment. Of the 15 measures assessed, none significantly differed among the groups. These null findings did not change in multivariate analyses. Our findings suggest that there is no differential sexual risk based on age among YBMSM and that this group should be considered a homogenous population with regards to intervention strategies that aim to reduce the sexual risk behaviors of YBMSM.

Although adolescents are at disproportionate risk for sexually transmitted infections, most sex education programs have shown little effect on sexual behavior. An interactive video intervention developed by our team has been identified as one of a few programs that have been documented to reduce sexually transmitted infections in this population. Building on behavioral decision research, we used a mental models approach to interview young women about their sexual decisions, finding, among other things, the strong role of perceived social norms. We based our intervention on these results, aiming to help young women identify and implement personally and socially acceptable decision strategies. A randomized controlled trial found that the video reduced risky sexual behavior and the acquisition of chlamydia infection. We recently revised the video to suit more diverse audiences, and upgraded it to modern standards of cinematography and interactivity. It is now in field trial. PMID:26149165

Every individual channels information differently based on their preference of the sensory modality or representational system (visual auditory or kinesthetic) we tend to favor most (our primary representational system (PRS)). Therefore, some of us access and store our information primarily visually first, some auditorily, and others kinesthetically (through feel and touch); which in turn establishes our information processing patterns and strategies and external to internal (and subsequently vice versa) experiential language representation. Because of the different ways we channel our information, each of us will respond differently to a task--the way we gather and process the external information (input), our response time (process), and the outcome (behavior). Traditional human models of decision making and response time focus on perception, cognitive and motor systems stimulated and influenced by the three sensory modalities, visual, auditory and kinesthetic. For us, these are the building blocks to knowing how someone is thinking. Being aware of what is taking place and how to ask questions is essential in assessing performance toward reducing human errors. Existing models give predications based on time values or response times for a particular event, and may be summed and averaged for a generalization of behavior(s). However, by our not establishing a basic understanding of the foundation of how the behavior was predicated through a decision making strategy process, predicative models are overall inefficient in their analysis of the means by which behavior was generated. What is seen is the end result

The pathophysiology of tinnitus is poorly understood and treatments are often unsuccessful. A number of animal models have been developed in order to gain a better understanding of tinnitus. A great deal has been learned from these models re-garding the electrophysiological and neuroanatomical correlates of tinnitus following exposure to noise or ototoxic drugs. Re-liable behavioral data is important for determining whether such electrophysiological or neuroanatomical changes are indeed related to tinnitus. Of the many documented tinnitus animal behavioral paradigms, the acoustic startle reflex had been pro-posed as a simple method to identify the presence or absence of tinnitus. Several behavioral models based on conditioned re-sponse suppression paradigms have also been developed. In addition to determining the presence or absence of tinnitus, some of the behavioral paradigms have provided signs of the onset, frequency, and intensity of tinnitus in animals. Although none of these behavioral models have been proved to be a perfect model, these studies provide useful information on understanding the neural mechanisms underlying tinnitus.

The rationality assumption that underlies mainstream economic theory has proved to be a useful approximation, despite the fact that systematic violations to its predictions can be found. That is, the assumption of rational behavior is useful in understanding the ways in which many successful economic institutions function, although it is also true that actual human behavior falls systematically short of perfect rationality. We consider a possible explanation of this apparent inconsistency, suggesting that mechanisms that rest on the rationality assumption are likely to be successful when they create an environment in which the behavior they try to facilitate leads to the best payoff for all agents on average, and most of the time. Review of basic learning research suggests that, under these conditions, people quickly learn to maximize expected return. This review also shows that there are many situations in which experience does not increase maximization. In many cases, experience leads people to underweight rare events. In addition, the current paper suggests that it is convenient to distinguish between two behavioral approaches to improve economic analyses. The first, and more conventional approach among behavioral economists and psychologists interested in judgment and decision making, highlights violations of the rational model and proposes descriptive models that capture these violations. The second approach studies human learning to clarify the conditions under which people quickly learn to maximize expected return. The current review highlights one set of conditions of this type and shows how the understanding of these conditions can facilitate market design. PMID:25024182
Full Text Available Purpose: This article informs readers about the theoretical and practical origins of the behaviorally informed interventions (BIPI, analyzes examples of the BIPI from different policy sectors and strategies they offer for policy and regulatory design, and discusses applications and implications of BIPI for public interventions Methodology: This paper is based on a review of literature, as well as an inspection of administrative practices in OECD countries. It encompasses a systematic analysis of scientific papers fromthe SCOPUS database and a query carried out at the library of George Washington University. Findings: The traditional approach to public policy research is based on rational choice theory. It offers limited support, because by assuming perfect rationality of policy decisions, it overlooks existence of systematic errors and biases of human decision-making. The authors argue that behaviorally informed public interventions (BIPI might contribute to improving the effectiveness of a number of public measures – regulation, projects, programs, and even entire policies. Practical implications: The behavioral approach allows decision-makers to better understand the decisions and behaviors of citizens, as well as to design more effective interventions with minimum effort by adapting the existing solutions to real decision mechanisms of citizens. Originality: By combining the concepts of traditional approach with the growing behavioral approach, the authors aim to propose a new theoretical framework (BIPI to be used as a tool for policy design, delivery and evaluation.

Most online services (Google, Facebook etc.) operate by providing a service to users for free, and in return they collect and monetize personal information (PI) of the users. This operational model is inherently economic, as the "good" being traded and monetized is PI. This model is coming under increased scrutiny as online services are moving to capture more PI of users, raising serious privacy concerns. However, little is known on how users valuate different types of PI while being online, as well as the perceptions of users with regards to exploitation of their PI by online service providers. In this paper, we study how users valuate different types of PI while being online, while capturing the context by relying on Experience Sampling. We were able to extract the monetary value that 168 participants put on different pieces of PI. We find that users value their PI related to their offline identities more (3 times) than their browsing behavior. Users also value information pertaining to financial transactio...

Iterated games provide a framework to describe social interactions among groups of individuals. Recent work stimulated by the discovery of "zero-determinant" strategies has rapidly expanded our ability to analyze such interactions. This body of work has primarily focused on games in which players face a simple binary choice, to "cooperate" or "defect". Real individuals, however, often exhibit behavioral diversity, varying their input to a social interaction both qualitatively and quantitatively. Here we explore how access to a greater diversity of behavioral choices impacts the evolution of social dynamics in finite populations. We show that, in public goods games, some two-choice strategies can nonetheless resist invasion by all possible multi-choice invaders, even while engaging in relatively little punishment. We also show that access to greater behavioral choice results in more "rugged " fitness landscapes, with populations able to stabilize cooperation at multiple levels of investment, such that choice f...

A classical way for exploring the scattering behavior of a small sphere is to approximate Mie coefficients with a Taylor series expansion. This ansatz delivered a plethora of insightful results, mostly for small spheres supporting electric localized plasmonic resonances. However, many scattering aspects are still uncharted, especially for the case of magnetic resonances. Here, an alternative system ansatz is proposed based on the Pad\\'e approximants for the Mie coefficients. The extracted results reveal new aspects, such as the existence of a self-regulating radiative damping mechanism for the first magnetic resonance. Hence, a systematic way of exploring the scattering behavior is introduced, sharpening our understanding about sphere's scattering behavior and its emergent functionalities.

Goal directed behavior is explained by two approaches: the first, which can be named as cybertetic (behavior is wieved as homeostatic and reflexive), and second, as cognitive approach, a learned response, (skills developed by whaching the behavior of another individual). The aim of the paper is to present a noninvasive method described as an interaction of human beings with environment, recording the electrical activity of the brain from the human scalp. Obtained results are in agreement of psychological theories that place at determined levels of age the acquisition of the capacities of abstract thinking and with the functional neuroanatomic studies according to which biological maturation is necessary for learning processes to develop. An acquired level of learning is in close relationship with the maturation level of the cerebral structures. PMID:27442417

This paper presents a novel methodology for modelling and analyzing of behav-ior relations of concurrent systems. The set of all firing sequences of a Petri net is an importanttool for describing the dynamic behavior of concurrent systems. In this paper, the behaviorrelativity of two concurrent subsystems in their synchronous composition is presented. Such be-havior relativities, including Controlled Relativity, United Relativity, Interactive Relativity andExclusive Relativity, are defined respectively. The properties of the relativities are discussed indetail. The analysis method for these properties is based on minimum T-invariants, when twosubsystems are live bounded Petri nets. A well-known example has also been analyaed usingthe new methodology to demonstrate the advantages of the proposed methodology.

Dialectical Behavior Therapy (DBT) and Mentalization-Based Treatment (MBT) are two approaches to the treatment of borderline personality disorder (BPD). While DBT has the most empirical support, MBT has a small but significant evidence base. Dialectical behavior therapy synthesizes behaviorism, mindfulness, and dialectics, while MBT is conceptually anchored in psychoanalysis, attachment theory, cognitive neuroscience, and developmental psychopathology. While coming from strikingly different orientations, DBT and MBT therapists share more interventions and stances than one might suppose. The central purported active ingredient of MBT is the capacity to mentalize, which is crucial for the formation of secure attachment, and this ability is thought to be weak and unstable in individuals with borderline personality disorder. This article explores the question of whether or not mentalizing is already present in DBT practice, whether it would be compatible with DBT conceptually and practically, and whether a focus on mentalizing would be of use to the DBT therapists and their patients.

Previous research suggests that reducing sedentary screen behaviors may be a strategy for preventing and treating obesity in children. This systematic review describes strategies used in interventions designed to either solely target sedentary screen behaviors or multiple health behaviors, including sedentary screen behaviors. Eighteen studies were included in this paper; eight targeting sedentary screen behaviors only, and ten targeting multiple health behaviors. All studies used behavior modification strategies for reducing sedentary screen behaviors in children (aged 1-12 years). Nine studies only used behavior modification strategies, and nine studies supplemented behavior modification strategies with an electronic device to enhance sedentary screen behaviors reductions. Many interventions (50%) significantly reduced sedentary screen behaviors; however the magnitude of the significant reductions varied greatly (-0.44 to -3.1 h/day) and may have been influenced by the primary focus of the intervention, number of behavior modification strategies used, and other tools used to limit sedentary screen behaviors.

The theory of planned behavior (TPB) has been successfully predicting behavior with a small number of factors. Nonetheless, to increase its predictive power we introduced several behavioral options and additional factors in the same prediction model about drivers’ self-reported speed behavior on a road with a speed limit of 90 km/h. We investigated the TPB factors as well as descriptive norms, perceived similarity with/description of the prototypical driver, and past behavior with re...

Chronic insomnia (symptoms for ≥ 6 months) is the most common sleep disorder, affecting 6% to 10% of adults in the general population, with even higher rates in patients with comorbid conditions (eg, hypertension, 44%; cardiac disease, 44.1%; breathing problems, 41.5%). Traditionally, chronic insomnia occurring with another condition has been considered secondary and rarely received direct treatment because treatment of the primary condition was expected to improve the insomnia. However, this approach often failed because chronic insomnia is maintained by behaviors, cognitions, and associations that patients adopt as they attempt to cope with poor sleep but that end up backfiring (eg, increasing caffeine, spending more time in bed, trying harder to sleep). Cognitive behavioral treatment of insomnia (CBTi) targets those behaviors, cognitions, and associations and is effective across a variety of populations, including those with medical and psychologic comorbidities. Thus, in 2005, a National Institutes of Health expert consensus panel on chronic insomnia recommended dropping the term "secondary insomnia" in favor of the term "comorbid insomnia." Because CBTi does not carry the risks associated with some sleep medications (eg, dependency, polypharmacy, cognitive and psychomotor impairment), it is an attractive option for patients with other conditions. Through the Society of Behavioral Sleep Medicine (www.behavioralsleep.org) and the American Board of Sleep Medicine (www.absm.org), it is possible to find practitioners with expertise in CBTi (as well as other aspects of behavioral sleep medicine) and other behavioral sleep resources. Given the currently limited number of trained practitioners, exploration of alternative delivery methods (eg, briefer protocols, self-help, Internet) to improve access to this highly effective treatment and expanded training in these treatments are warranted.

Bandura (1995) suggests that a "crusade against the causal efficacy of human thought" exists. The present paper disputes that claim, suggesting that the quest which does exist involves an understanding of self-efficacy. Examined are Bandura's shifting definitions of self-efficacy, his misunderstandings of others' work, and implications of some of his attempts to defend the construct. In the remainder of the paper Rotter's Social Learning Theory is discussed as a model of human choice behavior which recognizes the contributions of both cognitive and behavioral traditions within psychology, and has proven to be of great heuristic value.

Residential behavior-based (BB) programs use strategies grounded in the behavioral social sciences to influence household energy use. Strategies may include providing households with real-time or delayed feedback about their energy use; supplying energy-efficiency education and tips; rewarding households for reducing their energy use; comparing households to their peers; and establishing games, tournaments, and competitions. BB programs often target multiple energy end uses and encourage energy savings, demand savings, or both. Savings from BB programs are usually a small percentage of energy use, typically less than 5%.

Introduction: Health status and health-related quality of life of postmenopausal women are issues, which nowadays pose a serious challenge to many domains of science. Climacteric symptoms which occur at this stage of life, lower its quality and make a negative contribution to self-reported health status, are mostly observed in a particular group of women. Evaluation of health behaviors performed using a standardized questionnaire, the Health Behavior Inventory (HBI), may help establish a com...
Two bound, entangled fermions form a composite boson, which can be treated as an elementary boson as long as the Pauli principle remains irrelevant. The bosonic character of the composite is intimately linked to the entanglement of the fermions: Large entanglement implies good bosonic properties. The deviation from perfect bosonic behavior manifests itself in the statistical properties of the composites and in their collective interference. As a consequence, the counting statistics exhibited by composites allow one to infer the form of the two-fermion wave-function. Bosonic behavior can thus be used as a probe for the underlying structure of composite particles without directly accessing their constituents.

This issue of Focus on Suicide brings us new data about risk assessment, with 2 articles examining the utility of rating scales for assessment of suicidal behavior. Youngstrom et al conduct a careful comparison of 3 suicide rating scales: the Columbia Suicide Severity Rating Scale (C-SSRS), the Suicide Tracking Scale (STS), and the Sheehan Suicidality Tracking Scale (S-STS). While the scales did comparably in 2 broad categories, suicidal ideation and suicide attempts, the study suggests that some subtypes of suicidal behavior/ideation are not captured as well by the S-STS.

More specifically, social/person recognition memory is supposed, by behavioral-economic and game-theoretic analysis, to be required for tit- for-tat like cooperative behaviors to evolve under the N-person iterated prisoner fs dilemma game condition. Meanwhile, humans are known to show a social stress response during face-to-face social interactions, which might ...

Full Text Available The review of basic literary sources is made out of behavior of horse. On the basis of the field researches (visual supervisions after three different aged groups of mares it is built ethograms. An ethogram of behavioral forms among mares was developed. They represent the different forms of mares’ behavior in a dynamics. The reaction of mares of the different age-related and physiology groups on appearance of extraneous objects on a pasture, their activity, hierarchy, socialization is analyzed in groups. Several main studies on equines were reviewed in ethogram. Four objects were placed into the pasture with the mares and foals including a mat, cone, halter, and mounting block. Initial interest of mares in objects was high. Herd mentality highly evident. When one horse spooked at object the whole herd followed. After 5 minutes, majority of mares and foals lose interest in objects. The major general behavior categories observed include: locomotion, comfort, and harem social. Dominance was demonstrated while looking at the objects. Dominance was also demonstrated when a mare wanted to be in a specific place or play with a specific toy, she would pin her ears back, bite, or kick at the other mare.
