Sample records for resistance-curve r-curve behavior

  1. R-curve behavior and micromechanisms of fracture in resin based dental restorative composites. (United States)

    Shah, M B; Ferracane, J L; Kruzic, J J


    The fracture properties and micromechanisms of fracture for two commercial dental composites, one microhybrid (FiltekZ250) and one nanofill (FiltekSupreme Plus), were studied by measuring fracture resistance curves (R-curves) using pre-cracked compact-tension specimens and by conducting both unnotched and double notched four point beam bending experiments. Four point bending experiments showed about 20% higher mean flexural strength of the microhybrid composite compared to the nanofill. Rising fracture resistance was observed over approximately 1 mm of crack extension for both composites, and higher overall fracture resistance was observed for the microhybrid composite. Such fracture behavior was attributed to crack deflection and crack bridging toughening mechanisms that developed with crack extension, causing the toughness to increase. Despite the lower strength and toughness of the present nanofill composite, based on micromechanics observations, large nanoparticle clusters appear to be as effective at deflecting cracks and imparting toughening as solid particles. Thus, with further microstructural refinement, it should be possible to achieve a superior combination of aesthetic and mechanical performance using the nanocluster approach for dental composites.

    Exceptional fracture toughness levels exhibited by WC–Co cemented carbides (hardmetals) are due mainly to toughening derived from plastic stretching of crack-bridging ductile enclaves. This takes place due to the development of a multiligament zone at the wake of cracks growing in a stable manner. As a result, hardmetals exhibit crack growth resistance (R-curve) behavior. In this work, the toughening mechanics and mechanisms of these materials are investigated by combining experimental and analytical approaches. Focused Ion Beam technique (FIB) and Field-Emission Scanning Electron Microscopy (FESEM) are implemented to obtain serial sectioning and imaging of crack–microstructure interaction in cracks arrested after stable extension under monotonic loading. The micrographs obtained provide experimental proof of the developing multiligament zone, including failure micromechanisms within individual bridging ligaments. Analytical assessment of the multiligament zone is then conducted on the basis of experimental information attained from FIB/FESEM images, and a model for the description of R-curve behavior of hardmetals is proposed. It was found that, due to the large stresses supported by the highly constrained and strongly bonded bridging ligaments, WC–Co cemented carbides exhibit quite steep but short R-curve behavior. Relevant strength and reliability attributes exhibited by hardmetals may then be rationalized on the basis of such toughening scenario.

    Strength and reliability of WC-Co cemented carbides (hardmetals) are dependent on effective fracture toughness as well as on nature, size and distribution of processing flaws. Regarding toughness, they exhibit a crack growth resistance (R-curve) behavior, derived from the development of a multiligament bridging zone at the crack wake. Accordingly, successful implementation of fracture mechanics requires consideration of tangency criterion, between applied stress intensity factor and R-curve, ...

    This paper reports on transformation zone shape, size, and crack-growth-resistance behavior studied in precracked and annealed single-edge notch bend specimens of commercial-grade ceria-partially-stabilized zirconia polycrystals as a function of applied load. Well-defined transformation zones with a characteristic elongated shape in the plane of the crack were observed. It is shown that the observed zone shape is significantly different from the shape predicted by a combined shear/dilatation yield criterion and the stress field of the crack prior to the transformation. The length of the transformation zone directly ahead of the crack tip is in better agreement with the prediction of the Dugdale plastic strip zone mode. The fracture toughness increment showed the characteristic square root dependence on the transformation zone width, but the magnitude of the toughness increment was not consistent with the predictions of the theoretical models of transformation toughening

    Bone injures (BI) represents one of the major health problems, together with cancer and cardiovascular diseases. Assessment of the risks associated with BI is nontrivial since fragility of human cortical bone is varying with age. Due to restrictions for performing experiments on humans, only a limited number of fracture resistance curves (R-curves) for particular ages have been reported in the literature. This study proposes a novel decision support system for the assessment of bone fracture resistance by fusing various artificial intelligence algorithms. The aim was to estimate the R-curve slope, toughness threshold and stress intensity factor using the two input parameters commonly available during a routine clinical examination: patients age and crack length. Using the data from the literature, the evolutionary assembled Artificial Neural Network was developed and used for the derivation of Linear regression (LR) models of R-curves for arbitrary age. Finally, by using the patient (age)-specific LR models and diagnosed crack size one could estimate the risk of bone fracture under given physiological conditions. Compared to the literature, we demonstrated improved performances for estimating nonlinear changes of R-curve slope (R 2 = 0.82 vs. R 2 = 0.76) and Toughness threshold with ageing (R 2 = 0.73 vs. R 2 = 0.66).

  9. Characterization of KS-material by means of J-R-curves especially using the partial unloading technique

    International Nuclear Information System (INIS)

    Voss, B.; Blauel, J.G.; Schmitt, W.


    Essential components of nuclear reactor systems are fabricated from materials of high thoughness to exclude brittle failure. With increasing load, a crack tip will blunt, a plastic zone will be formed, voids may nucleate and coalesce thus initiating stable crack extension when the crack driving parameter, e.g. J, exceeds the initiation value Jsub(i). Further stable crack growth will occur with further increasing J prior to complete failure of the structure. The specific material resistance against crack extension is characterized by J resistance curves Jsub(R)=J(Δa). ASTM provides a standard to determine the initiation toughness Jsub(Ic) from a Jsub(R)-curve [1] and a tentative standard for determining the Jsub(R)-curve by a single specimen test [2]. To generate a Jsub(R)-curve values for the crack driving parameter J and the corresponding stable crack growth Δa have to be measured. Besides the multiple specimen technique [1], the potential drop and especially the partial unloading compliance method [2] are used to measure stable crack growth. Some special problems and some results for pressure vessel steels are discussed in this paper. (orig./RW)

  10. R-Curve Approach to Describe the Fracture Resistance of Tool Steels (United States)

    Picas, Ingrid; Casellas, Daniel; Llanes, Luis


    This work addresses the events involved in the fracture of tool steels, aiming to understand the effect of primary carbides, inclusions, and the metallic matrix on their effective fracture toughness and strength. Microstructurally different steels were investigated. It is found that cracks nucleate on carbides or inclusions at stress values lower than the fracture resistance. It is experimentally evidenced that such cracks exhibit an increasing growth resistance as they progressively extend, i.e., R-curve behavior. Ingot cast steels present a rising R-curve, which implies that the effective toughness developed by small cracks is lower than that determined with long artificial cracks. On the other hand, cracks grow steadily in the powder metallurgy tool steel, yielding as a result a flat R-curve. Accordingly, effective toughness for this material is mostly independent of the crack size. Thus, differences in fracture toughness values measured using short and long cracks must be considered when assessing fracture resistance of tool steels, especially when tool performance is controlled by short cracks. Hence, material selection for tools or development of new steel grades should take into consideration R-curve concepts, in order to avoid unexpected tool failures or to optimize microstructural design of tool steels, respectively.

  11. Standard test method for K-R curve determination

    1.1 This test method covers the determination of the resistance to fracture of metallic materials under Mode I loading at static rates using either of the following notched and precracked specimens: the middle-cracked tension M(T) specimen or the compact tension C(T) specimen. A K-R curve is a continuous record of toughness development (resistance to crack extension) in terms of KR plotted against crack extension in the specimen as a crack is driven under an increasing stress intensity factor, K. 1.2 Materials that can be tested for K-R curve development are not limited by strength, thickness, or toughness, so long as specimens are of sufficient size to remain predominantly elastic to the effective crack extension value of interest. 1.3 Specimens of standard proportions are required, but size is variable, to be adjusted for yield strength and toughness of the materials. 1.4 Only two of the many possible specimen types that could be used to develop K-R curves are covered in this method. 1.5 The test is app...

  12. Contributions to the R-curve behaviour of ceramic materials

    International Nuclear Information System (INIS)

    Fett, T.


    Several ceramic materials show an increase in crack growth resistance with increasing crack extension. Especially, in case of coarse-grained alumina this ''R-curve effect'' is caused by crack-face interactions in the wake of the advancing crack. Similar effects occur for whisker reinforced ceramics. Due to the crack-face interactions so-called ''bridging stresses'' are generated which transfer forces between the two crack surfaces. A second reason for an increase of crack-growth resistance are stress-induced phase transformations in zirconia ceramics with the tetragonal phase changing to the monoclinic phase. These transformations will affect the stress field in the surroundings of crack tips. The transformation generates a crack-tip transformation zone and, due to the stress balance, also residual stresses in the whole crack region which result in a residual stress intensity factor. This additional stress intensity factor is also a reason for the R-curve behaviour. In this report both effects are outlined in detail. (orig.) [de

  13. Crack resistance curve determination of zircaloy-4 cladding

    Energy Technology Data Exchange (ETDEWEB)

    Bertsch, J.; Alam, A.; Zubler, R


    Fracture mechanics properties of fuel claddings are of relevance with respect to fuel rod integrity. The integrity of a fuel rod, in turn, is important for the fuel performance, for the safe handling of fuel rods, for the prevention of leakages and subsequent dissemination of fuel, for the avoidance of unnecessary dose rates, and for safe operation. Different factors can strongly deteriorate the mechanical fuel rod properties: irradiation damage, thermo-mechanical impact, corrosion or hydrogen uptake. To investigate the mechanical properties of fuel rod claddings which are used in Swiss nuclear power plants, PSI has initiated a program for mechanical testing. A major issue was the interaction between specific loading devices and the tested cladding tube, e.g. in the form of bending or friction. Particular for Zircaloy is the hexagonal closed packed structure of the zirconium crystallographic lattice. This structure implies plastic deformation mechanisms with specific, preferred orientations. Further, the manufacturing procedure of Zircaloy claddings induces a specific texture which plays a salient role with respect to the embrittlement by irradiation or integration of hydrogen in the form of hydrides. Both, the induced microstructure as well as the plastic deformation behaviour play a role for the mechanical properties. At PSI, in a first step inactive thin walled Zircaloy tubes and, for comparison reasons, plates were tested. The validity of the mechanical testing of the non standard tube and plate geometries had to be verified. The used Zircaloy-4 cladding tube sections and small plates of the same wall thickness have been notched, fatigue pre-cracked and tensile tested to evaluate the fracture toughness properties at room temperature, 300 {sup o}C and 350 {sup o}C. The crack propagation has been determined optically. The test results of the plates have been further used to validate FEM calculations. For each sample a complete crack resistance (J-R) curve could

    A generalised approach is presented to derive coupled mixed mode cohesive laws described with physical parameters such as peak traction, critical opening, fracture energy and cohesive shape. The approach is based on deriving mix mode fracture resistance curves from an effective mix mode cohesive...... law at different mode mixities. From the fracture resistance curves, the normal and shear stresses of the cohesive laws can be obtained by differentiation. Since, the mixed mode cohesive laws are obtained from a fracture resistance curve (potential function), path independence is automatically...... satisfied. The effective mix mode cohesive law can have different shape and cohesive law parameters at different mode mixities so that the approach can be applied to various material failure models....

    Lebey, J.; Roche, R.L.


    Increasing attention has been given in fracture mechanics to the use of the J concept not only as a criterion of the onset of crack propagation, but also as an aid in the study of propagation stability. As a consequence, there is a need to determine the variation of J with crack extension, this being usually presented in curves known as J-R curves. Earlier methods for determining such curves used several specimens. The present paper describes a procedure avoiding any direct measurement of the crack length and giving a correct value of J when crack propagation occurs. (author)

  16. Mechanistic aspects of fracture and R-curve behavior in elk antler bone

    Energy Technology Data Exchange (ETDEWEB)

    Launey, Maximilien E.; Chen, Po-Yu; McKittrick, Joanna; Ritchie, Robert O.


    Bone is an adaptative material that is designed for different functional requirements; indeed, bones have a variety of properties depending on their role in the body. To understand the mechanical response of bone requires the elucidation of its structure-function relationships. Here, we examine the fracture toughness of compact bone of elk antler which is an extremely fast growing primary bone designed for a totally different function than human (secondary) bone. We find that antler in the transverse (breaking) orientation is one of the toughest biological materials known. Its resistance to fracture is achieved during crack growth (extrinsically) by a combination of gross crack deflection/twisting and crack bridging via uncracked 'ligaments' in the crack wake, both mechanisms activated by microcracking primarily at lamellar boundaries. We present an assessment of the toughening mechanisms acting in antler as compared to human cortical bone, and identify an enhanced role of inelastic deformation in antler which further contributes to its (intrinsic) toughness.

    In this study, the effect of shape parameters on the J-R curves of curved CT specimens was evaluated using the limit load method. Fracture toughness tests considering the shape factors L/W and Rm/t of the specimens were also performed. Thereafter, the J-R curves of the curved CT specimens were compared using the J-integral equation proposed in the ASTM (American Society for Testing and Materials) and limit load solution. The J-R curves of the curved CT specimens were also compared with those of the CWP (curved wide plate), which is regarded to be similar to real pipe and standard specimens.. Finally, the effectiveness of the J-R curve of each curved CT specimen was evaluated. The results of this study can be used for assessing the applicability of curved CT specimens in the accurate evaluation of the fracture toughness of real pipes.

The experiments were conducted in an environmental...... displayed distinctly different R-curve behaviours. The difference was related to different toughening mechanisms as the two composites had markedly different microstructures. Contrary to common experience, the composite with the finer microstructure (smaller particles), the Concept Advanced®, showed...... significantly higher fracture resistance than the composite with the coarser microstructure. The fracture properties were related to the flexural strength of the dental composites. The method, thus, can provide useful insight into how the microstructure enhances toughness, which is necessary for the future...

  19. More basic approach to the analysis of multiple specimen R-curves for determination of J/sub c/

    International Nuclear Information System (INIS)

    Carlson, K.W.; Williams, J.A.


    Multiple specimen J-R curves were developed for groups of 1T compact specimens with different a/W values and depth of side grooving. The purpose of this investigation was to determine J/sub c/ (J at onset of crack extension) for each group. Judicious selection of points on the load versus load-line deflection record at which to unload and heat tint specimens permitted direct observation of approximate onset of crack extension. It was found that the present recommended procedure for determining J/sub c/ from multiple specimen R-curves, which is being considered for standardization, consistently yielded nonconservative J/sub c/ values. A more basic approach to analyzing multiple specimen R-curves is presented, applied, and discussed. This analysis determined J/sub c/ values that closely corresponded to actual observed onset of crack extension

  20. On-line inspection of weld quality based on dynamic resistance curve in resistance spot welding and weldbonding (United States)

    Sun, Haitao; Zhang, Yansong; Lai, Xinmin; Chen, Guanlong


    In order to reduce destructive testing of car sub-assemblies, on-line inspection of weld quality has gained more and more concern in terms of both resistance spot welding (RSW) and weldbonding. Dynamic resistance directly determines the amount of heat generated by current flow and consequently reflects nugget formation and growth, which is one of the most effective technologies for quality inspection. Under the measurements of voltage and current at the secondary circuit of a welding transformer, this paper proposes a method for on-line inspection of weld quality based on two indicators from dynamic resistance curve: time to nugget initiation and durable time to nugget expansion. Firstly, during the welding process of RSW and weldbonding, the proper range of time to nugget initiation and durable time to nugget expansion for good welds is set up. Then on-line inspection of weld quality on the basis of the developed proper range of these two indicators is carried out. The experimental results show the following conclusions: it is clearly able to separate accepted welds without expulsion from the welds of unaccepted nugget size in both RSW and weldbonding; the proper range for good welds, independent of electrode wear, is obtained only for a new electrode.

  1. Fracture behavior of quasi-brittle materials (United States)

    Tandon, Sanjeev


    Cementitious materials are widely used in structural applications such as high rise buildings, dams, and aircraft runways. One limitation in the use of these materials is their low toughness. The intent of this work is to examine, firstly, the effect of loading rate on toughening and the evolution of resistance (R-) curves of cement paste, mortar and concrete, and, secondly and more importantly, to explain the differences in the microstructural aspects of the fracture surface which accompany the change in the loading rate. To obtain a better understanding of the toughening mechanisms active in cementitious materials, alumina was used as a model material. Resistance curves of fine-grained alumina were found to be independent of crack length. Coarse-grained alumina exhibited strongly rising R-curves. In both aluminas, the initial fracture toughness, Ksb{o}, was found to be independent of the loading rate. In coarse-grained alumina, the net toughening, Ksb{max}, was found to decrease with increasing loading rate. A rate-dependent coefficient of friction was incorporated into a crack bridging model to understand the effect of loading rate on toughness. Predictions based on the bridging model, using the measured coefficient of friction for coarse-grained alumina, were in good agreement with observed phenomenon. The relationship between loading rate effects on toughening and microstructural complexity of cementitious materials was investigated in cement paste, mortar, and concrete. For cement paste, fracture toughness was found to be independent of crack growth. Mortar and concrete exhibited strongly rising R-curves. In the case of cement paste and mortar, the peak fracture toughness, Ksb{max}, was found to be independent of the loading rate. In concrete, the peak toughness was found to decrease with increasing loading rate. Surface roughness measurements were performed to understand the effect of loading rate on the fracture mechanisms. The results of the roughness

    Operational definition of J concept is first examined. Then it is shown that conventional methods of experimental determination of J values are based on the following assumption: if the load-deflexion curve is known for one value of the crack length it is possible to know the load-deflexion curve for any value of the crack length. This assumption is generalized with the help of scale functions and formula giving J are deduced. Attention is given to the effect of crack propagation on J values. The same assumption is used to extract the crack length from the load-deflexion curve. As the real crack lengths are known before propagation occurs and at the end of the test, it is possible to achieve a good calibration of the material characteristic [fr

  5. Damage Tolerance Behavior of Friction Stir Welds in Aluminum Alloys (United States)

    McGill, Preston; Burkholder, Jonathan


    Friction stir welding is a solid state welding process used in the fabrication of various aerospace structures. Self-reacting and conventional friction stir welding are variations of the friction stir weld process employed in the fabrication of cryogenic propellant tanks which are classified as pressurized structure in many spaceflight vehicle architectures. In order to address damage tolerance behavior associated with friction stir welds in these safety critical structures, nondestructive inspection and proof testing may be required to screen hardware for mission critical defects. The efficacy of the nondestructive evaluation or the proof test is based on an assessment of the critical flaw size. Test data describing fracture behavior, residual strength capability, and cyclic mission life capability of friction stir welds at ambient and cryogenic temperatures have been generated and will be presented in this paper. Fracture behavior will include fracture toughness and tearing (R-curve) response of the friction stir welds. Residual strength behavior will include an evaluation of the effects of lack of penetration on conventional friction stir welds, the effects of internal defects (wormholes) on self-reacting friction stir welds, and an evaluation of the effects of fatigue cycled surface cracks on both conventional and selfreacting welds. Cyclic mission life capability will demonstrate the effects of surface crack defects on service load cycle capability. The fracture data will be used to evaluate nondestructive inspection and proof test requirements for the welds.

    Low alloy ferritic steels are widely used in nuclear industry for the construction of pressure vessels. Pressure vessel forged low alloy steels 20MnMoNi55 (modified) have been developed indigenously. Experiments have been carried out to study the Low Cycle Fatigue (LCF) and fracture behavior of these forged steels. Fully reversed strain controlled LCF testing at room temperature and at 350 °C has been carried out at a constant strain rate, and for different axial strain amplitude levels. LCF material behavior has been studied from cyclic stress-strain responses and the strain-life relationships. Fracture behavior of the steel has been studied based on tests carried out for crack growth rate and fracture toughness (J-R curve). Further, responses of fatigue crack growth rate tests have been compared with the rate evaluated from fatigue precracking carried out for fracture toughness (J-R) tests. Fractography of the samples have been carried out to reveal dominant damage mechanisms in crack propagation and fracture. The fatigue and fracture properties of indigenously developed low alloy steel 20MnMoNi55 (modified) steels are comparable with similar class of steels. (author)

  7. Elastic-plastic fracture toughness and rising JR-curve behavior of cortical bone is partially protected from irradiation-sterilization-induced degradation by ribose protectant. (United States)

    Woodside, Mitchell; Willett, Thomas L


    This study tested the hypothesis that pre-treating cortical bone with ribose would protect the rising fracture resistance curve behavior and crack initiation fracture toughness of both bovine and human cortical bone from the degrading effects of γ-irradiation sterilization. A ribose pre-treatment (1.8 M for bovine, and 1.2 M for human, in PBS at 60 °C for 24 h) was applied to single-edge notched bending fracture specimens prior to sterilization with a 33 kGy dose of γ-irradiation. Fracture resistance curves were generated with a single specimen method using an optical crack length measurement technique. The effect of the treatment on overall fracture resistance behavior, crack initiation fracture toughness, and tearing modulus was compared with non-irradiated and conventionally irradiation sterilized controls. Hydrothermal isometric tension testing was used to examine collagen network connectivity and thermal stability to explore relationships between collagen network quality and fracture resistance. The ribose pre-treatment successfully protected the crack growth initiation fracture toughness of bovine and human bone by 32% and 63%, respectively. The rising JR-curve behavior was also partially protected. Furthermore, collagen connectivity and thermal stability followed similar patterns to those displayed by fracture toughness. This paper demonstrates that the fracture toughness of irradiation-sterilized bone tissue can be partially protected with a ribose pre-treatment. This new approach shows potential for the production and clinical application of sterilized allografts with improved mechanical performance and durability. Copyright © 2016 Elsevier Ltd.

  9. Opposite change trend of electrical behavior curves near the threshold between GaAs- and GaN-multi-quantum-well laser diodes (United States)

    Feng, Liefeng; Wang, Shupeng; Li, Yang; Yang, Xiufang; Li, Ding; Wang, Cunda


    The opposite and abrupt change trends of the electrical behavior between narrow and wide bang-gap multi-quantum-well (MQW) laser diodes (LDs) in the `threshold region', which corresponds to the current region between two kinks in the Id V/d I- I curves, were confirmed from the apparent properties measured directly and junction properties extracted by our ac-IV method, as well as simulation calculations. In the threshold region, negative capacitance and series resistance curves in narrow bandgap LDs (wavelengths are 780 and 650 nm) drop down, while in wide-bandgap LDs (wavelengths are 450 and 405 nm), they jump up; the junction voltage curves in narrow bandgap LDs jump up, while in wide-bandgap LDs, they drop down. We qualitatively interpreted the opposite change trend of these electrical parameters, and concluded that different stimulated emission mechanisms caused this opposite change trend of LDs with these two types of materials.

    The recent history and current status of the area of verbal behavior are considered in terms of three major thematic lines: the operant conditioning of adult verbal behavior, learning to be an effective speaker and listener, and developments directly related to Skinner's Verbal Behavior. Other topics not directly related to the main themes are also considered: the work of Kurt Salzinger, ape-language research, and human operant research related to rule-governed behavior.

In the process, PB has become a new generation of behaviorism with abundant heuristic avenues for development in theory, philosophy, methodology, and research. Psychology has resources, purview and problem areas, and nascent developments of many kinds, gathered in chaotic diversity, needing unification (and other things) that cognitivism cannot provide.

  16. On the dynamic behavior of mineralized tissues (United States)

    Kulin, Robb Michael

    Mineralized tissues, such as bone and antler, are complex hierarchical materials that have adapted over millennia to optimize strength and fracture resistance for their in vivo applications. As a structural support, skeletal bone primarily acts as a rigid framework that is resistant to fracture, and able to repair damage and adapt to sustained loads during its lifetime. Antler is typically deciduous and subjected to large bending moments and violent impacts during its annual cycle. To date, extensive characterization of the quasi-static mechanical properties of these materials has been performed. However, very little has been done to characterize their dynamic properties, despite the fact that the majority of failures in these materials occur under impact loads. Here, an in depth analysis of the dynamic mechanical behavior of these two materials is presented, using equine bone obtained post-mortem from donors ranging in age from 6 months to 28 years, and antler from the North American Elk. Specimens were tested under compressive strain rates of 10-3, 100, and 103 sec-1 in order to investigate their strain rate dependent compressive response. Fracture toughness experiments were performed using a four-point bending geometry on single and double-notch specimens in order to measure fracture toughness, as well as observe differences in crack propagation between dynamic (˜2x105 MPa˙m1/2/s) and quasi-static (˜0.25 MPa˙m1/2/s) loading rates. After testing, specimens were analyzed using a combination of optical, electron and confocal microscopy. Results indicated that the mechanical response of these materials is highly dependent on loading rate. Decreasing quasi-static fracture toughness is observed with age in bone specimens, while dynamic specimens show no age trends, yet universally decreased fracture toughness compared to those tested quasi-statically. For the first time, rising R-curve behavior in bone was also shown to exist under both quasi-static and dynamic

  17. Teleological behaviorism. (United States)

    Rachlin, H


    A psychological science of efficient causes, using internal mechanisms to explain overt behavior, is distinguished from another psychological science, based on Aristotelian final causes, using external objects and goals to explain overt behavior. Efficient-cause psychology is designed to answer the question of how a particular act is emitted; final-cause psychology is designed to answer the question of why a particular act is emitted. Physiological psychology, modern cognitive psychology, and some parts of behaviorism including Skinnerian behaviorism are efficient-cause psychologies; final-cause psychology, a development of Skinnerian behaviorism, is here called teleological behaviorism. Each of these two conceptions of causality in psychology implies a different view of the mind, hence a different meaning of mental terms.

  20. Behaviorally inadequate

    DEFF Research Database (Denmark)

    Kasperbauer, Tyler Joshua


    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...... 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 the role...

  1. Effects of crack front curvature on J–R curve testing using clamped SE(T) specimens of homogeneous materials

    International Nuclear Information System (INIS)

    Huang, Yifan; Zhou, Wenxing


    Three-dimensional (3D) finite element analyses (FEA) of clamped single-edge tension (SE(T)) specimens are performed to investigate the impact of the crack front curvature on the elastic compliance, compliance rotation correction factor and average J-integral evaluated over the crack front. Specimens with six average crack lengths (i.e. a ave /W = 0.2–0.7) and three thickness-to-width ratios (i.e. B/W = 0.5, 1 and 2) are analyzed. The curved crack front is assumed to be bowed symmetrically and characterized by a power-law expression with a wide range of curvatures. Several crack front straightness requirements for SE(B) and C(T) specimens specified in BS7448, ISO and ASTM E1820 standards are reviewed. Based on results of the numerical investigation, new crack front straightness criteria for the SE(T) specimen are proposed in the context of the nine-point measurement by using as a criterion that the errors in the estimated compliance and average J values should be no more than five percent. The proposed criteria depend on both a ave /W and B/W, and are more advantageous than those specified in the BS, ISO and ASTM standards in terms of controlling the differences in J and compliance between the specimens with curved and straight crack fronts. - Highlights: • Investigate the impacts of crack front curvature on the compliance, rotation correction factor and J for SE(T) specimens. • Validate the applicabilities of crack front straightness criteria specified in the seven test standards on SE(T) specimens. • Recommend new crack front straightness criteria for the SE(T) specimen.

  2. Cost Behavior

    DEFF Research Database (Denmark)

    Hoffmann, Kira

    The objective of this dissertation is to investigate determinants and consequences of asymmetric cost behavior. Asymmetric cost behavior arises if the change in costs is different for increases in activity compared to equivalent decreases in activity. In this case, costs are termed “sticky......” if the change is less when activity falls than when activity rises, whereas costs are termed “anti-sticky” if the change is more when activity falls than when activity rises. Understanding such cost behavior is especially relevant for decision-makers and financial analysts that rely on accurate cost information...

    Each addictive disorder has specific characteristics. It is essential to consider them in order to improve the treatment. However, the combination of behavioral addictions and substance use disorders is valid, as showed by the next version of the DSM. During the treatment, it is important to evaluate cross, but also longitudinal, considering the current problematic behavior, but also the problematic behaviors that occurred in the past and that may occur in the future. There is indeed a significant risk of switching addiction. The relapse prevention must consider this risk and be inclusive. Copyright © 2012. Published by Elsevier Masson SAS.

While the standard academic finance emphasizes theories such as modern portfolio theory and the efficient market hypothesis, the behavioral finance investigates the psychological and sociological issues that impact the decision-making process of individuals, groups and organizations. Most of the research behind behavioral finance has been empirical in nature, concentrating on what people do and why. The research has shown that people do not always act rationally, nor they fully utilise all information available to them.

  8. Behavioral variability as avoidance behavior. (United States)

    Fonseca Júnior, Amilcar Rodrigues; Leite Hunziker, Maria Helena


    This study aimed to investigate whether variable patterns of responses can be acquired and maintained by negative reinforcement under an avoidance contingency. Six male Wistar rats were exposed to sessions in which behavioral variability was reinforced according to a Lag contingency: Sequences of three responses on two levers had to differ from one, two or three previous sequences for shocks to be avoided (Lag 1, Lag 2 and Lag 3, respectively). Performance under the Lag conditions was compared with performance on a Yoke condition in which the animals received the same reinforcement frequency and distribution as in the Lag condition but behavioral variability was not required. The results showed that most of the subjects varied their sequences under the Lag contingencies, avoiding shocks with relatively high probability (≥ 0.7). Under the Yoke procedure, responding continued to occur with high probability, but the behavioral variability decreased. These results suggest that behavioral variability can be negatively reinforced. © 2017 Society for the Experimental Analysis of Behavior.

  9. Behavior subtraction (United States)

    Jodoin, Pierre-Marc; Saligrama, Venkatesh; Konrad, Janusz


    Network video cameras, invented in the last decade or so, permit today pervasive, wide-area visual surveillance. However, due to the vast amounts of visual data that such cameras produce human-operator monitoring is not possible and automatic algorithms are needed. One monitoring task of particular interest is the detection of suspicious behavior, i.e., identification of individuals or objects whose behavior differs from behavior usually observed. Many methods based on object path analysis have been developed to date (motion detection followed by tracking and inferencing) but they are sensitive to motion detection and tracking errors and are also computationally complex. We propose a new surveillance method capable of abnormal behavior detection without explicit estimation of object paths. Our method is based on a simple model of video dynamics. We propose one practical implementation of this general model via temporal aggregation of motion detection labels. Our method requires little processing power and memory, is robust to motion segmentation errors, and general enough to monitor humans, cars or any other moving objects in uncluttered as well as highly-cluttered scenes. Furthermore, on account of its simplicity, our method can provide performance guarantees. It is also robust in harsh environments (jittery cameras, rain/snow/fog).

    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...

  14. OPEC behavior (United States)

    Yang, Bo

    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.

  15. Behavioral epigenetics. (United States)

    Moore, David S


    Why do we grow up to have the traits we do? Most 20th century scientists answered this question by referring only to our genes and our environments. But recent discoveries in the emerging field of behavioral epigenetics have revealed factors at the interface between genes and environments that also play crucial roles in development. These factors affect how genes work; scientists now know that what matters as much as which genes you have (and what environments you encounter) is how your genes are affected by their contexts. The discovery that what our genes do depends in part on our experiences has shed light on how Nature and Nurture interact at the molecular level inside of our bodies. Data emerging from the world's behavioral epigenetics laboratories support the idea that a person's genes alone cannot determine if, for example, he or she will end up shy, suffering from cardiovascular disease, or extremely smart. Among the environmental factors that can influence genetic activity are parenting styles, diets, and social statuses. In addition to influencing how doctors treat diseases, discoveries about behavioral epigenetics are likely to alter how biologists think about evolution, because some epigenetic effects of experience appear to be transmissible from generation to generation. This domain of research will likely change how we think about the origins of human nature.

  16. Feeding behavior. (United States)

    Ralston, S L


    Problems related to feeding behavior in horses fall into three main categories: underconsumption, overconsumption, and abnormal consumption. Anorexia may be caused by a variety of diseases and overcome by removing the underlying causes (pain, fever), and physical or chemical stimulation of appetite. "Hypophagia" may be caused by poor dentition, disease, or stress. Again, removal of the cause or stimulation by physical or chemical means may improve intakes. Acute and chronic overconsumption of feeds are reflections of the normal controls (or lack thereof) of feeding in the horse. The only reliable prevention is to limit access to feeds. Abnormal eating behaviors such as pica or coprophagy are usually caused by a dietary imbalance or boredom. Coprophagey, however, is a normal behavior in young foals. Drinking disorders are rare, the only common one being the avoidance of "strange" water. Masking water at home with specific flavors such as peppermint or vinegar may encourage the horse to drink water from other sources to which the "home" flavor has been added.

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...

    Pantalone, David W; Czajkowski, Stephanie E; Taylor, S Wade

    In this chapter, we will describe the state of the literature on behavioral health, which includes mental health and substance use problems, and the available treatment interventions to ameliorate these problems, for older adults living with HIV (OALH). The scientific literature on the behavioral health of OALH is highly underdeveloped, especially in terms of the creation of empirically supported interventions to alleviate psychological distress. From the literature that does exist, there are a number of salient factors that emerge, including stereotypes (i.e., older adults are not sexually active), stigmatization (of those who are HIV-positive), social isolation, unique psychosocial needs for newly-infected OALH, and elevated rates of emotional distress and concomitant disorders - especially, depression. These factors persist alongside findings that OALH have fewer sources of social or institutional support, fewer surviving peers, and a lack of family to care for them. Additionally, many OALH report problems with substance use, both as a function of their 'baby-boomer' generational status (i.e., people born between 1946 and 1964) and in terms of the life experiences associated with their HIV-positive status. Overall, it is unclear how mental health and substance use problems affect combination antiretroviral therapy adherence, multimorbidity, polypharmacy, or treatment outcomes in this population, and further study is needed. © 2017 S.

  20. Sweetness concentration-response behavior of rebiana at room and refrigerator temperatures. (United States)

    Fry, John C; Yurttas, Nese; Biermann, Kari L


    Rebiana is a zero-calorie, natural, high-potency sweetener derived from Stevia rebaudiana Bertoni and comprising almost pure rebaudioside A. Reliable information on its sweetness concentration-response (C-R) behavior is fundamental to rebiana's use as an ingredient. The response curve of rebiana in room-temperature (21 °C) and refrigerated (5 °C) water was determined using 2-alternative forced choice discrimination tests with a minimum of 70 tasters. From a series of panels the proportion of tasters finding different sucrose concentrations sweeter than a fixed concentration of rebiana was plotted against sucrose concentration. The resultant sigmoid curves were linearized by transforming the ordinate axis to a probability scale. This aided experimental design and determination of isosweet concentrations. The latter were deemed to be the sucrose concentration at which 50% of tasters found it to be the sweeter of the pair. Isosweet concentrations of sucrose for seven rebiana concentrations up to 600 mg/L were used to construct a C-R curve for each temperature. Equations were derived for the resultant hyperbolic curves. Rebiana is significantly more potent in cold water. Rebiana is a new, zero-calorie, natural, high-potency sweetener derived from the Stevia plant. We have measured the sweetness of rebiana over a range of concentrations at room and refrigerator temperatures. This information will help developers of low-calorie products get the right sweetness level when replacing sugar with rebiana. © 2011 Institute of Food Technologists®

  1. Ductile fracture behavior of 6-inch diameter type 304 stainless steel and STS 42 carbon steel piping containing a through-wall or part-through crack

    International Nuclear Information System (INIS)

    Shibata, Katsuyuki; Ohba, Toshihiro; Kawamura, Takaichi; Miyazono, Shohachiro; Kaneko, Tadashi; Yokoyama, Norio.


    The double ended guillotine break philosophy in the design base accident of the nuclear power plant is considered to be overly conservative from the view point of piping design. Through the past experiences and developments of the fabrication, inspection, and operation of nuclear power plants, it has been recognized that the Leak-Before-Break (LBB) concept can be justified in the LWR pressure boundary pipings. In order to verify the LBB concept, extensive experimental and theoretical works are being conducted in many countries. Furthermore, a revised piping design standard, in which LBB concept is introduced, is under preparation in Japan, U.S.A., and European countries. At JAERI, a research program to investigate the unstable ductile fracture behavior of LWR piping under bending load has been carried out as a part of the LBB verification researches since 1983. This report summarizes the result of the ductile fracture tests conducted at room temperature in 1983 and 84. The 6-inch diameter pipes of type 304 stainless steel and STS 42 carbon steel pipe with a through-wall or part-through crack were tested under bending load with low or high compliance condition at room temperature. Pipe fracture data were obtained from the test as regards to load- displacement curve, crack extension, net section stress, J-resistance curve, and so on. Besides, the influence of the compliance on the fracture behavior was examined. Discussions are performed on the ductile pipe fracture criterion, flaw evaluation criterion, and LBB evaluation method.

  2. Surface modification of carbon/epoxy prepreg using oxygen plasma and its effect on the delamination resistance behavior of carbon/epoxy composites

    International Nuclear Information System (INIS)

    Kim, M.H.; Rhee, K.Y.; Kim, H.J.; Jung, D.H.


    It was shown in previous study that the fracture toughness of carbon/epoxy laminated composites could be significantly improved by modifying the surface of the prepreg using Ar + irradiation in an oxygen environment. In this study, the surface of carbon/epoxy prepreg was modified using an oxygen plasma to improve the delamination resistance behavior of carbon/epoxy laminated composites. The variation of the contact angle on the prepreg surface was determined as a function of the modification time, in order to determine the optimal modification time. An XPS analysis was conducted to investigate the chemical changes on the surface of the prepreg caused by the plasma modification. Mode I delamination resistance curves of the composites with and without surface modification were plotted as a function of the delamination increment. The results showed that the contact angle varied from ∼64 o to ∼47 o depending on the modification time and reached a minimum for a modification time of 30 min. The XPS analysis showed that the hydrophilic carbonyl C=O group was formed by the oxygen plasma modification. The results also showed that the delamination resistance behavior was significantly improved by the plasma modification of the prepreg. This improvement was caused by the better layer-to-layer adhesion as well as increased interfacial strength between the fibers and matrix

  3. Some verbal behavior about verbal behavior


    Salzinger, Kurt


    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.

  4. Behavioral economics. (United States)

    Chambers, David W


    It is human nature to overestimate how rational we are, both in general and even when we are trying to be. Such irrationality is not random, and the search for and explanation of patterns of fuzzy thinking is the basis for a new academic discipline known as behavioral economics. Examples are given of some of the best understood of our foibles, including prospect theory, framing, anchoring, salience, confirmation bias, superstition, and ownership. Humans have two cognitive systems: one conscious, deliberate, slow, and rational; the other fast, pattern-based, emotionally tinged, and intuitive. Each is subject to its own kind of error. In the case of rational thought, we tend to exaggerate our capacity; for intuition, we fail to train it or recognize contexts where it is inappropriate. Humans are especially poor at estimating probabilities, or even understanding what they are. It is a common human failing to reason backwards from random outcomes that are favorable to beliefs about our power to predict the future. Five suggestions are offered for thinking within our means.

  9. The Psyche as Behavior

    Directory of Open Access Journals (Sweden)



    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.

  10. On the effect of x-ray irradiation on the deformation and fracture behavior of human cortical bone

    Energy Technology Data Exchange (ETDEWEB)

    Barth, Holly D.; Launey, Maximilien E.; McDowell, Alastair A.; Ager III, Joel W.; Ritchie, Robert O.


    In situ mechanical testing coupled with imaging using high-energy synchrotron x-ray diffraction or tomography imaging is gaining in popularity as a technique to investigate micrometer and even sub-micrometer deformation and fracture mechanisms in mineralized tissues, such as bone and teeth. However, the role of the irradiation in affecting the nature and properties of the tissue is not always taken into account. Accordingly, we examine here the effect of x-ray synchrotron-source irradiation on the mechanistic aspects of deformation and fracture in human cortical bone. Specifically, the strength, ductility and fracture resistance (both work-of-fracture and resistance-curve fracture toughness) of human femoral bone in the transverse (breaking) orientation were evaluated following exposures to 0.05, 70, 210 and 630 kGy irradiation. Our results show that the radiation typically used in tomography imaging can have a major and deleterious impact on the strength, post-yield behavior and fracture toughness of cortical bone, with the severity of the effect progressively increasing with higher doses of radiation. Plasticity was essentially suppressed after as little as 70 kGy of radiation; the fracture toughness was decreased by a factor of five after 210 kGy of radiation. Mechanistically, the irradiation was found to alter the salient toughening mechanisms, manifest by the progressive elimination of the bone's capacity for plastic deformation which restricts the intrinsic toughening from the formation 'plastic zones' around crack-like defects. Deep-ultraviolet Raman spectroscopy indicated that this behavior could be related to degradation in the collagen integrity.

    Kwon, Jae Do; Lee, Yong Seon; Park, Jung Cheol; In, Jae Hyeon; Woo, Seung Wan; Pae, Yong Tak; Nam, Uk Hui; Park, Yun Won [Yeungnam Univ., Gyeongsan (Korea, Republic of)


    The following investigations are performed in order to estimate the mechanism of the structural integrity, and the life prediction. The CF8M is observed a brittle behavior in the range of 475 .deg. C. The five classes of the thermally aged CF8M specimen are prepared using an artificially accelerated aging method. Namely, after the specimen are held for 100, 300, 900, 1800 and 3600 hrs. at 430 .deg. C respectively, the specimen are water cooled to room temperature. In addition to the thermally aged specimens the specimens associated with {delta}-phase degradation are prepared. After the specimens are maintained for 20 min, 5, 15, 50 and 150 hrs. at 700 .deg. C, respectively. which is in the range of {delta}-phase degradation, all specimens are cooled in water. The impact energy variations are measured for both the aged and virgin specimen at -173, -70, -32, 27 and 100 .deg. C, respectively, through the Charpy impact tests in addition to the hardness tests. The characteristics of the fatigue crack growth and low cycle fatigue tests are investigated using both aged and virgin specimens. Also fractured surfaces of the specimen are observed using the scanning electronic microscopy. J-R curve and J{sub IC} of the aged and virgin specimens are found J{sub IC} in order to predict the critical flaw size and fatigue life.

  12. Revival of ferromagnetic behavior in charge-ordered Pr0.75Na0.25MnO3 manganite by ruthenium doping at Mn site and its MR effect (United States)

    Elyana, E.; Mohamed, Z.; Kamil, S. A.; Supardan, S. N.; Chen, S. K.; Yahya, A. K.


    Ru doping in charge-ordered Pr0.75Na0.25Mn1-xRuxO3 (x = 0-0.1) manganites was studied to investigate its effect on structure, electrical transport, magnetic properties, and magnetotransport properties. DC electrical resistivity (ρ), magnetic susceptibility, and χ' measurements showed that sample x = 0 exhibits insulating behavior within the entire temperature range and antiferromagnetic (AFM) behavior below the charge-ordering (CO) transition temperature TCO of 221 K. Ru4+ substitution (x>0.01) suppressed the CO state, which resulted in the revival of paramagnetic to ferromagnetic (FM) transition at the Curie temperature Tc, increasing from 120 K (x = 0.01) to 193 K (x = 0.1). Deviation from the Curie-Weiss law above Tc in the 1/χ' versus T plot for x = 0.01 doped samples indicated the existence of Griffiths phase with Griffith temperature at 169 K. Electrical resistivity measurements showed that Ru4+ substitution increased the metallic-to-insulating transition temperature TMI from 144 K (x = 0.01) to 192 K (x = 0.05) due to enhanced double-exchange mechanism, but TMI decreased to 176 K (x = 0.1) probably due to the existence of AFM clusters within the FM domain. The present work also discussed the possible theoretical models at the resistivity curve of Pr0.75Na0.25Mn1-xRuxO3 (x = 0-0.1) for the entire temperature range.

  13. Fracture toughness and fracture behavior of CLAM steel in the temperature range of 450 °C-550 °C (United States)

    Zhao, Yanyun; Liang, Mengtian; Zhang, Zhenyu; Jiang, Man; Liu, Shaojun


    In order to analyze the fracture toughness and fracture behavior (J-R curves) of China Low Activation Martensitic (CLAM) steel under the design service temperature of Test Blanket Module of the International Thermonuclear Experimental Reactor, the quasi-static fracture experiment of CLAM steel was carried out under the temperature range of 450 °C-550 °C. The results indicated that the fracture behavior of CLAM steel was greatly influenced by test temperature. The fracture toughness increased slightly as the temperature increased from 450 °C to 500 °C. In the meanwhile, the fracture toughness at 550 °C could not be obtained due to the plastic deformation near the crack tip zone. The microstructure analysis based on the fracture topography and the interaction between dislocations and lath boundaries showed two different sub-crack propagation modes: growth along 45° of the main crack direction at 450 °C and growth perpendicular to the main crack at 500 °C.

  14. Toward a behavioral ecology of rescue behavior. (United States)

    Hollis, Karen L; Nowbahari, Elise


    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.

  17. Computational Analysis of Behavior. (United States)

    Egnor, S E Roian; Branson, Kristin


    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.

  5. Countercontrol in behavior analysis. (United States)

    Delprato, Dennis J


    Countercontrol is a functional class of behavior that is part of Skinner's analysis of social behavior. Countercontrol refers to behavioral episodes comprised of socially mediated aversive controlling conditions and escape or avoidance responses that do not reinforce, and perhaps even punish, controllers' responses. This paper suggests that neglect of countercontrol in modern behavior analysis is unfortunate because the concept applies to interpersonal and social relations the fundamental operant principle that human behavior is both controlled and controlling-humans are not passive and inflexible. Countercontrol is addressed here in terms of conceptual status, contemporary developments in behavior analysis, its importance in a behavior-analytic approach to freedom and cultural design, applications, and research. The main conclusion is that Skinner's formulation of counter-control is scientifically supported and worthy of increased prominence in behavior analysis.

  15. Determination of J-integral R-curves for the pressure vessel material A 533 B1 using the potential drop technique and the multi-specimen method

    International Nuclear Information System (INIS)

    Krompholz, K.; Ullrich, G.


    J-integral experiments at room temperature were performed on three point bend type specimens of the nuclear pressure vessel material A 533 B1 with a/w-ratios of 0.3 and 0.5. Following the ASTM-proposal for the multi-specimen technique a value is obtained close to the value obtained in the HSST round robin test. On the other hand, from the measurement of the Jsub(IC)-value by means of the potential drop technique there is an indication that a lower value of Jsub(IC) is correct. This is in agreement with the multi-specimen technique using linear regression lines without excluding 'invalid' points. That is reasonable if fractographic investigations gives clear indications that stable crack growth has occurred as is the case in this work. (Auth.)

  17. Behaviorism and Society. (United States)

    Krapfl, Jon E


    A probable list of causes for the limited acceptance of behaviorism in our society is identified. This is followed by a summary review of the proposed solutions identified in other papers in this special issue of The Behavior Analyst, most of which relate to either better marketing of either the behavior analytic process or the results achieved as a consequence. One paper proposes a more broad conception of behavior analysis. This paper endorses the solutions identified in previous papers and then goes on to propose an even more broad conception of behavior analysis and makes the point that behavior analysis is unlikely to flourish unless behavior analysts understand a good deal more about the cultural and other contextual features of the environments in which they work.

  18. Behavioral Immunity in Insects

    Directory of Open Access Journals (Sweden)

    Thierry Lefèvre


    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.

  20. Role of microstructure in the aging-related deterioration of the toughness of human cortical bone

    International Nuclear Information System (INIS)

    Nalla, R.K.; Kruzic, J.J.; Kinney, J.H.; Balooch, M.; Ager, J.W.; Ritchie, R.O.


    The aging-related deterioration of the fracture properties of bone, coupled with higher life expectancy, is responsible for increasing incidence of bone fracture in the elderly; consequently, an understanding of how these fracture properties degrade with age is essential. In this study, ex vivo fracture experiments have been performed to quantitatively assess the effect of age on human cortical bone in the proximal-distal orientation, i.e., longitudinally along the osteons. Because cortical bone exhibits rising crack-growth resistance with crack extension, the toughness is evaluated in terms of resistance-curve (R-curve) behavior, measured for bone taken from wide range of age groups (34-99 years). Using this approach, both the crack-initiation and crack-growth toughness are determined and are found to deteriorate with age; the initiation toughness decreases some 40% over six decades from 40 to 100 years, while the growth toughness is effectively eliminated over the same age range. The reduction in crack-growth toughness is considered to be associated primarily with a degradation in the degree of extrinsic toughening, in particular, involving crack bridging in the wake of the crack. An examination of the micro-/nano-structural changes accompanying the process of aging, using optical microscopy, X-ray tomography, nanoindentation and Raman spectroscopy, is shown to support such observations

  1. Approach behavior as information. (United States)

    van Uijen, Sophie L; van den Hout, Marcel A; Engelhard, Iris M


    Anxious individuals infer danger from information about physiological responses, anxiety responses, and safety behaviors. This study investigated whether anxious individuals also infer safety from approach behavior. 325 students rated the danger they perceived in general and spider-relevant scenarios in which information about objective safety versus objective danger, and approach behavior versus no approach behavior, was varied. A high and low spider fearful group was created with a median split on spider fear. Participants with a high fear of spiders, compared to participants with low spider fear, rated spider scenarios with approach behavior as safer than spider scenarios without approach behavior. This effect was similar for objectively dangerous and safe spider scenarios. No behavior as information effects were found for general scenarios. The data were collected in a non-clinical student sample. Spider fearful individuals infer safety from approach behavior in spider-relevant scenarios. For spider fearful individuals, approach behavior may add to the beneficial effects of exposure therapy. Future research is needed to investigate whether patients with anxiety disorders also show a tendency to infer safety from approach behavior. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. Introduction to behavioral addictions. (United States)

    Grant, Jon E; Potenza, Marc N; Weinstein, Aviv; Gorelick, David A


    Several behaviors, besides psychoactive substance ingestion, produce short-term reward that may engender persistent behavior, despite knowledge of adverse consequences, i.e., diminished control over the behavior. These disorders have historically been conceptualized in several ways. One view posits these disorders as lying along an impulsive-compulsive spectrum, with some classified as impulse control disorders. An alternate, but not mutually exclusive, conceptualization considers the disorders as non-substance or "behavioral" addictions. Inform the discussion on the relationship between psychoactive substance and behavioral addictions. We review data illustrating similarities and differences between impulse control disorders or behavioral addictions and substance addictions. This topic is particularly relevant to the optimal classification of these disorders in the forthcoming fifth edition of the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Growing evidence suggests that behavioral addictions resemble substance addictions in many domains, including natural history, phenomenology, tolerance, comorbidity, overlapping genetic contribution, neurobiological mechanisms, and response to treatment, supporting the DSM-V Task Force proposed new category of Addiction and Related Disorders encompassing both substance use disorders and non-substance addictions. Current data suggest that this combined category may be appropriate for pathological gambling and a few other better studied behavioral addictions, e.g., Internet addiction. There is currently insufficient data to justify any classification of other proposed behavioral addictions. Proper categorization of behavioral addictions or impulse control disorders has substantial implications for the development of improved prevention and treatment strategies.

  3. Complexity and behavioral economics. (United States)

    Rosser, J Barkley; Rosser, Marina V


    This paper will consider the relationship between complexity economics and behavioral economics. A crucial key to this is to understand that Herbert Simon was both the founder of explicitly modern behavioral economics as well as one of the early developers of complexity theory. Bounded rationality was essentially derived from Simon's view of the impossibility of full rationality on the part of economic agents. Modern complexity theory through such approaches as agent-based modeling offers an approach to understanding behavioral economics by allowing for specific behavioral responses to be assigned to agents who interact within this context, even without full rationality. Other parts of modern complexity theory are considered in terms of their relationships with behavioral economics. Fundamentally, complexity provides an ultimate foundation for bounded rationality and hence the need to use behavioral economics in a broader array of contexts than most economists have thought appropriate.

  4. Sociopathic behavior and dementia. (United States)

    Cipriani, Gabriele; Borin, Gemma; Vedovello, Marcella; Di Fiorino, Andrea; Nuti, Angelo


    The maintenance of appropriate social behavior is a very complex process with many contributing factors. Social and moral judgments rely on the proper functioning of neural circuits concerned with complex cognitive and emotional processes. Damage to these systems may lead to distinct social behavior abnormalities. When patients present with dysmoral behavior for the first time, as a change from a prior pervasive pattern of behavior, clinicians need to consider a possible, causative brain disorder. The aim is to explore sociopathy as a manifestation of dementia. We searched electronic databases and key journals for original research and review articles on sociopathy in demented patients using the search terms "sociopathy, acquired sociopathy, sociopathic behavior, dementia, and personality". In conclusion, dementia onset may be heralded by changes in personality including alteration in social interpersonal behavior, personal regulation, and empathy. The sociopathy of dementia differs from antisocial/psychopathic personality disorders.

    Glial cells constitute about 10 % of the Drosophila nervous system. The development of genetic and molecular tools has helped greatly in defining different types of glia. Furthermore, considerable progress has been made in unraveling the mechanisms that control the development and differentiation of Drosophila glia. By contrast, the role of glia in adult Drosophila behavior is not well understood. We here summarize recent work describing the role of glia in normal behavior and in Drosophila models for neurological and behavioral disorders.

  12. Suicide and Suicidal Behavior (United States)

    Nock, Matthew K.; Borges, Guilherme; Bromet, Evelyn J.; Cha, Christine B.; Kessler, Ronald C.; Lee, Sing


    Suicidal behavior is a leading cause of injury and death worldwide. Information about the epidemiology of such behavior is important for policy-making and prevention. The authors reviewed government data on suicide and suicidal behavior and conducted a systematic review of studies on the epidemiology of suicide published from 1997 to 2007. The authors' aims were to examine the prevalence of, trends in, and risk and protective factors for suicidal behavior in the United States and cross-nationally. The data revealed significant cross-national variability in the prevalence of suicidal behavior but consistency in age of onset, transition probabilities, and key risk factors. Suicide is more prevalent among men, whereas nonfatal suicidal behaviors are more prevalent among women and persons who are young, are unmarried, or have a psychiatric disorder. Despite an increase in the treatment of suicidal persons over the past decade, incidence rates of suicidal behavior have remained largely unchanged. Most epidemiologic research on suicidal behavior has focused on patterns and correlates of prevalence. The next generation of studies must examine synergistic effects among modifiable risk and protective factors. New studies must incorporate recent advances in survey methods and clinical assessment. Results should be used in ongoing efforts to decrease the significant loss of life caused by suicidal behavior. PMID:18653727

    Full Text Available The study of behavioral finance combines the investigation and expertise from research and practice into smart portfolios of individual investors’ portfolios. Understanding cognitive errors and misleading emotions drive investors to their long-term goals of financial prosperity and capital preservation. 10 years ago, Behavioral Finance was still considered an incipient, adolescent science. First Nobel Prize in Economics awarded to the study of Behavioral Economics in 2002 established the field as a new, respected study of economics. 2013 Nobel Prize was awarded to three economists, one of them considered the one of the founders of the Behavioral Finance. As such, by now we are entering the coming of age of behavioral finance. It is now recognized as a science of understanding investors behaviors and their biased patterns. It applies quantitative finance and provides practical models grounded on robust understanding of investors behavior toward financial risk. Financial Personality influences investment decisions. Behavioral portfolio construction methods combine classic finance with rigorously quantified psychological metrics and improves models for financial advice to enhance investors chances in reaching their lifetime financial goals. Behavioral finance helps understanding psychological profile dissimilarities of individuals and how these differences manifest in investment decision process. This new science has become now a must topic in modern finance.

  4. The J-integral concept for elastic-plastic material behavior

    International Nuclear Information System (INIS)

    Schmitt, W.; Kienzler, R.


    A simple analytical extension of the J integral has been presented which extends the J concept to apply for materials described by an incremental theory of plasticity. The stress work density replacing the strain energy density is load-history dependent. The J integral may be made path independent by virtue of an additional volume integral and may be understood as work dissipation rate. The discussion of the consequences for the applicability of the J concept to describe fracture processes showed that validity criteria proposed in the standards are not sufficient to yield configuration-independent J-resistance curves. However, a possibility is sketched to assess those structure-dependent resistance curves based on plastic-collapse considerations. With 6 figs., 33 refs

  5. Reporting unethical research behavior. (United States)

    Wenger, N S; Korenman, S G; Berk, R; Liu, H


    Scientists, as professionals, have a responsibility to self-regulate. However, whistleblowing is rare. We investigated scientists' infrequent disclosure of unethical behavior by studying their responses to scenarios describing unethical research acts and compared their responses to those of research administrators. A cross-sectional survey was administered to National Science Foundation-funded principal investigators and their institutions' representatives (IRs) to the Office of Research Integrity. Both scientists and IRs proposed to respond to nearly all research behaviors that they rated as unethical. Scientists more often proposed responses limited to the research team (58% vs. 25% of cases, p unethical behavior were not. Scientists appear to perceive that they uphold their responsibility to respond to unethical behavior by disclosures within the research team, whereas administrators propose to report to externally accountable individuals, raising the question of whether scientists' behavior constitutes professional self-regulation or cover up.

The most cited articles in the field and within each journal are also examined. The comprehensive literature review of consumer behavior research undertaken in this article could advance the discipline of consumer behavior research by elucidating the evolution of consumer behavior literature in the studied period.

  7. What determines our behavior

    Directory of Open Access Journals (Sweden)

    Marko Radovan


    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.

  8. Towards Behavioral Reflexion Models (United States)

    Ackermann, Christopher; Lindvall, Mikael; Cleaveland, Rance


    Software architecture has become essential in the struggle to manage today s increasingly large and complex systems. Software architecture views are created to capture important system characteristics on an abstract and, thus, comprehensible level. As the system is implemented and later maintained, it often deviates from the original design specification. Such deviations can have implication for the quality of the system, such as reliability, security, and maintainability. Software architecture compliance checking approaches, such as the reflexion model technique, have been proposed to address this issue by comparing the implementation to a model of the systems architecture design. However, architecture compliance checking approaches focus solely on structural characteristics and ignore behavioral conformance. This is especially an issue in Systems-of- Systems. Systems-of-Systems (SoS) are decompositions of large systems, into smaller systems for the sake of flexibility. Deviations of the implementation to its behavioral design often reduce the reliability of the entire SoS. An approach is needed that supports the reasoning about behavioral conformance on architecture level. In order to address this issue, we have developed an approach for comparing the implementation of a SoS to an architecture model of its behavioral design. The approach follows the idea of reflexion models and adopts it to support the compliance checking of behaviors. In this paper, we focus on sequencing properties as they play an important role in many SoS. Sequencing deviations potentially have a severe impact on the SoS correctness and qualities. The desired behavioral specification is defined in UML sequence diagram notation and behaviors are extracted from the SoS implementation. The behaviors are then mapped to the model of the desired behavior and the two are compared. Finally, a reflexion model is constructed that shows the deviations between behavioral design and implementation. This

    Yang, Zhiyin; Su, Zhonghua; Ji, Feng; Zhu, Min; Bai, Bo


    Behavior modification, as the core of clinical behavioral medicine, is often used in clinical settings. We seek to summarize behavior modification techniques that are commonly used in clinical practice of behavioral medicine in China and discuss possible biobehavioral mechanisms. We reviewed common behavior modification techniques in clinical settings in China, and we reviewed studies that explored possible biobehavioral mechanisms. Commonly used clinical approaches of behavior modification in China include behavior therapy, cognitive therapy, cognitive-behavioral therapy, health education, behavior management, behavioral relaxation training, stress management intervention, desensitization therapy, biofeedback therapy, and music therapy. These techniques have been applied in the clinical treatment of a variety of diseases, such as chronic diseases, psychosomatic diseases, and psychological disorders. The biobehavioral mechanisms of these techniques involve the autonomic nervous system, neuroendocrine system, neurobiochemistry, and neuroplasticity. Behavior modification techniques are commonly used in the treatment of a variety of somatic and psychological disorders in China. Multiple biobehavioral mechanisms are involved in successful behavior modification.

  6. Francis Bacon's behavioral psychology. (United States)

    MacDonald, Paul S


    Francis Bacon offers two accounts of the nature and function of the human mind: one is a medical-physical account of the composition and operation of spirits specific to human beings, the other is a behavioral account of the character and activities of individual persons. The medical-physical account is a run-of-the-mill version of the late Renaissance model of elemental constituents and humoral temperaments. The other, less well-known, behavioral account represents an unusual position in early modern philosophy. This theory espouses a form of behavioral psychology according to which (a) supposed mental properties are "hidden forms" best described in dispositional terms, (b) the true character of an individual can be discovered in his observable behavior, and (c) an "informed" understanding of these properties permits the prediction and control of human behavior. Both of Bacon's theories of human nature fall under his general notion of systematic science: his medical-physical theory of vital spirits is theoretical natural philosophy and his behavioral theory of disposition and expression is operative natural philosophy. Because natural philosophy as a whole is "the inquiry of causes and the production of effects," knowledge of human nature falls under the same two-part definition. It is an inquisition of forms that pertains to the patterns of minute motions in the vital spirits and the production of effects that pertains both to the way these hidden motions produce behavioral effects and to the way in which a skillful agent is able to produce desired effects in other persons' behavior.

    Directory of Open Access Journals (Sweden)

    Bachmanov Alexander A


    Full Text Available Abstract This review focuses on behavioral genetic studies of sweet, umami, bitter and salt taste responses in mammals. 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.

  8. Manipulation of choice behavior


    Manzini, Paola; Mariotti, Marco; Tyson, Christopher J.


    We introduce and study the problem of manipulation of choice behavior. In a class of two-stage models of decision making, with the agent's choices determined by three "psychological variables," we imagine that a subset of these variables can be selected by a "manipulator." To what extent does this confer control of the agent's behavior? Within the specified framework, which overlaps with two existing models of choice under cognitive constraints, we provide a complete answer to this question.

  10. Nonlinearities in Behavioral Macroeconomics. (United States)

    Gomes, Orlando


    This article undertakes a journey across the literature on behavioral macroeconomics, with attention concentrated on the nonlinearities that the behavioral approach typically suggests or implies. The emphasis is placed on thinking the macro economy as a living organism, composed of many interacting parts, each one having a will of its own, which is in sharp contrast with the mechanism of the orthodox view (well represented by the neoclassical or new Keynesian dynamic stochastic general equilibrium - DSGE - model). The paper advocates that a thorough understanding of individual behavior in collective contexts is the only possible avenue to further explore macroeconomic phenomena and the often observed 'anomalies' that the benchmark DSGE macro framework is unable to explain or justify. After a reflection on the role of behavioral traits as a fundamental component of a new way of thinking the economy, the article proceeds with a debate on some of the most relevant frameworks in the literature that somehow link macro behavior and nonlinearities; covered subjects include macro models with disequilibrium rules, agent-based models that highlight interaction and complexity, evolutionary switching frameworks, and inattention based decision problems. These subjects have, as a fundamental point in common, the use of behavioral elements to transform existing interpretations of the economic reality, making it more evident how irregular fluctuations emerge and unfold on the aggregate.

  11. Jayapura Teenagers Smoking Behavior. (United States)

    Herawati, Lucky; Budiman, Johan Arief; Haryono, W; Mulyani, Wiwiek


    Smoking behavior is a threat for Indonesian teenagers, including in the city of Jayapura, Papua province. The purpose of this study was to access Jayapura teenagers smoking behavior and knowledge including parents and other family members. The study was conducted on 78 respondents (grade 7, aged 11-14 years old), using cluster random sampling for selecting the public and private junior high school in Jayapura. The data collected was smoking behavior of respondents, parents and other family members (using self-reported questionnaire), and respondents' knowledge about the dangers of smoking (using tests with Cronbach's alpha 0.701). Data were analyzed descriptively and analytically using Chi-square, 95 % level of significant. The results showed 29.3 % of teenagers, 69.23 % of parents and 25.6 % of other family members were smokers, their knowledge was low (an average score of 60.81 out of 100), there was no significant statistical relationship between knowledge and smoking behavior among respondents (p = 0.079), and there is no significant relationship between teenagers behavior with the behavior of the parents (p = 0.609) and other family members (p = 0.578), 87 % of teenagers became smokers because there were individuals who smoke at home.

  13. Magnetic disordered in Ti doped ErCo{sub 2} alloys: Griffiths-like behavior

    Energy Technology Data Exchange (ETDEWEB)

    Oener, Y., E-mail: [Department of Physics, Faculty of Science and Letters, Istanbul Technical University, 34469 Maslak, Istanbul (Turkey); Guillot, M. [Laboratoire National des Champs Magnetiques Intenses, Grenoble Toulouse, CNRS, B.P. 166, 38042 Grenoble Cedex 9 (France)


    We report electrical and magnetic properties of ErCo{sub (2-x)}Ti{sub x} (x=0, 0.01, 0.02, 0.03, 0.04, 0.05) in the temperature range 4-300 K. The substitution of Ti for Co causes no change in the crystal structure of ErCo{sub 2} (cubic Laves phase C15 with space group Fd3{sup Macron }m). The lattice parameter, a, decreases almost linearly with increasing x up to x=0.04 and then increases slightly for the largest Ti concentration. The Curie temperature, T{sub c} is closely correlated with the lattice parameter. All resistivity curves exhibit a jump-like drop at T{sub c}, which is the characteristic sign of the first order transition. The temperature dependence of the resistivity was analyzed using a conventional model for RCo{sub 2} alloys. We have also investigated the role of the chemical disorder in the resistivity. The temperature dependence of the resistivity and the residual resistivity vs. x are interpreted consistently, considering the existence of some Co-rich ordered regions due to the quenched-in chemical disorder. Low-field magnetization measurements were carried out in the temperature range 4-100 K. The inverse susceptibility, 1/{chi}, shows non-linear behavior vs. temperature above T{sub c} for all samples except ErCo{sub 2}. We used three different approaches to determine the magnetic moment per formula unit: modified Curie-Weiss type paramagnetism, Neel type paramagnetism, and Griffiths-like behavior. A detailed analysis of the magnetization at low-fields reveals the complexity of the magnetic state both in the ordered and paramagnetic phases. However, the findings in the paramagnetic regime suggest that an interpretation based on the formation of a Griffiths phase is most plausible. High-field magnetization (up to 23 T) was also investigated in a wide temperature range below and above T{sub c}. In the paramagnetic regime, the magnetization data were described satisfactorily with the Landau theory. Landau coefficients a{sub 1} and a{sub 3} were

    Fatma Gul Helvaci Celik


    Full Text Available The deliberate self-harm behaviour which defined as attempting to own body resulting in tisue damage without conscious desire of peolple to die, is a major public health problem worldwide. The causes of deliberate self- harm, risk factors, the relationship between mental disorders and treatment strategies are not fully known. Deliberate self- harm can be observed together with psychiatric disorders such as borderline personality disorder, histrionic personality disorder, eating disorders and mood disorders. Also, deliberate self-harm must be distinguished from suicidal behavior. Psychologi-cal trauma has been suggested as a risk factor for deliberate self- harm behavior. Trauma and traumatic events have long been associated with deliberate self- harm behavior. The aim of this review article is to investigate the etiology and epidemiology of deliberate self-harm behaviour and relationship between psychiatric disorders.

  18. Behavioral contagion in sibships. (United States)

    Jones, D R; Jones, M B


    A behavior is "contagious" if one person is more likely to exhibit it when a relevant other person has already done so. In this sense, behavioral contagion is commonly thought to contribute to many social problems, such as drug abuse and teenage promiscuity. In this paper we focus on behavioral contagion in sibships. Borrowing a model from the theory of contagious diseases, we show that contagion will cause prevalence to increase with sibship size. This model also allows us to estimate the magnitude of the contagious factor relative to non-contagious factors. Finally, we develop two statistical tests for the presence of contagion. Results are presented for participation in a skill-development program and four child-psychiatric conditions: neurosis, hyperactivity, somatization, and conduct disorder. Evidence is presented that program participation is probably contagious and conduct disorder possibly so. The other three child-psychiatric conditions are shown not to be contagious. Implications for research and practice are discussed.

    DEFF Research Database (Denmark)

    Koch, Alexander Karl; Nafziger, Julia; Nielsen, Helena Skyt


    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....

    Orlando, Jillian M


    Behavioral problems of companion animals are becoming more widely recognized. As a result, there are a growing number of behavioral nutraceuticals and diets on the market. These products may be useful for the treatment of mild conditions, for clients who are hesitant to give their pet a psychopharmacologic agent, or sometimes in conjunction with psychopharmacologic agents. Veterinarians should critically review the research associated with nutraceuticals and diets, and have an understanding of the functional ingredients and their mechanisms of action before prescribing treatment.

  2. Mathematics as verbal behavior. (United States)

    Marr, M Jackson


    "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. Copyright © 2015 Elsevier B.V. All rights reserved.

  3. Irrational Human Behaviors

    Directory of Open Access Journals (Sweden)

    Orhan Şener


    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.

  12. Towards accurate emergency response behavior

    International Nuclear Information System (INIS)

    Sargent, T.O.


    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

  13. Behaviorism, private events, and the molar view of behavior. (United States)

    Baum, William M


    Viewing the science of behavior (behavior analysis) to be a natural science, radical behaviorism rejects any form of dualism, including subjective-objective or inner-outer dualism. Yet radical behaviorists often claim that treating private events as covert behavior and internal stimuli is necessary and important to behavior analysis. To the contrary, this paper argues that, compared with the rejection of dualism, private events constitute a trivial idea and are irrelevant to accounts of behavior. Viewed in the framework of evolutionary theory or for any practical purpose, behavior is commerce with the environment. By its very nature, behavior is extended in time. The temptation to posit private events arises when an activity is viewed in too small a time frame, obscuring what the activity does. When activities are viewed in an appropriately extended time frame, private events become irrelevant to the account. This insight provides the answer to many philosophical questions about thinking, sensing, and feeling. Confusion about private events arises in large part from failure to appreciate fully the radical implications of replacing mentalistic ideas about language with the concept of verbal behavior. Like other operant behavior, verbal behavior involves no agent and no hidden causes; like all natural events, it is caused by other natural events. In a science of behavior grounded in evolutionary theory, the same set of principles applies to verbal and nonverbal behavior and to human and nonhuman organisms.

  15. Integrative Behavioral Couple Therapy. (United States)

    Christensen, Andrew; Doss, Brian D


    Integrative Behavioral Couple Therapy (IBCT) is based in part on traditional behavioral couple therapy but expands both the conceptualization of couple distress and of intervention. The efficacy of IBCT has been supported in three clinical trials, including one with five year follow-up. Additionally, the effectiveness of IBCT in the real world has been supported through a system-wide dissemination effort in the United States Department of Veteran's Affairs. The reach of IBCT has also been extended through an online program,, based on IBCT. A nationwide clinical trial with a representative sample of the US population demonstrated the effectiveness of this program on both relationship and individual variables.

  16. Metacognition in addictive behaviors. (United States)

    Spada, Marcantonio M; Caselli, Gabriele; Nikčević, Ana V; Wells, Adrian


    Over the last twenty years metacognitive theory has provided a novel framework, in the form of the Self-Regulatory Executive Function (S-REF) model, for conceptualizing psychological distress (Wells & Matthews, 1994, 1996). The S-REF model proposes that psychological distress persists because of unhelpful coping styles (e.g. extended thinking and thought suppression) which are activated and maintained as a result of metacognitive beliefs. This paper describes the S-REF model and its application to addictive behaviors using a triphasic metacognitive formulation. Evidence on the components of the triphasic metacognitive formulation is reviewed and the clinical implications for applying metacognitive therapy to addictive behaviors outlined.

    Sandra Sequeira; Simeon Djankov


    This paper investigates how corruption affects firrm behavior. Firms can engage in two types of corruption when seeking a public service: cost-reducing "collusive" corruption and cost increasing "coercive" corruption. Using an original and unusually rich dataset on bribe payments at ports matched to firrm-level data, we observe how firms respond to each type of corruption by adjusting their shipping and sourcing strategies. "Collusive" corruption is associated with higher usage of the corrupt...

    Behaviorism, both as a psychological research program and a philosophical doctrine, was once a very popular and promising theory, the extension of which had a great impact on various fields such as socio-political theory and education. Both behaviorist movements actually shared something in common, which is to bring the downfall of the Cartesian metaphysics, in which the mental is understood as something essentially private and subjective. In this work, first I will briefly go over the genera...

  7. Electricity curtailment behaviors in Greek households: Different behaviors, different predictors

    International Nuclear Information System (INIS)

    Botetzagias, Iosif; Malesios, Chrisovaladis; Poulou, Dimitra


    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

  8. Analysis of Health Behavior Theories for Clustering of Health Behaviors. (United States)

    Choi, Seung Hee; Duffy, Sonia A

    The objective of this article was to review the utility of established behavior theories, including the Health Belief Model, Theory of Reasoned Action, Theory of Planned Behavior, Transtheoretical Model, and Health Promotion Model, for addressing multiple health behaviors among people who smoke. It is critical to design future interventions for multiple health behavior changes tailored to individuals who currently smoke, yet it has not been addressed. Five health behavior theories/models were analyzed and critically evaluated. A review of the literature included a search of PubMed and Google Scholar from 2010 to 2016. Two hundred sixty-seven articles (252 studies from the initial search and 15 studies from the references of initially identified studies) were included in the analysis. Most of the health behavior theories/models emphasize psychological and cognitive constructs that can be applied only to one specific behavior at a time, thus making them not suitable to address multiple health behaviors. However, the Health Promotion Model incorporates "related behavior factors" that can explain multiple health behaviors among persons who smoke. Future multiple behavior interventions guided by the Health Promotion Model are necessary to show the utility and applicability of the model to address multiple health behaviors.

  11. Attitude and behavior are correlates (United States)

    Shrigley, Robert L.

    Science attitude scales can be expected to predict science-related behavior. But A-B correspondence can seldom be expected to approach the r value of 1.00. Attitude and behavior covary to the degree that valid measurement and mediating variables are considered: Individual differences of subjects (e.g., high versus low self-monitoring); the social situation (e.g., direct experience); cognitive factors (e.g., attitude accessibility in memory). Attitude and behavior are reciprocal; that is, attitude can follow behavior. Variables other than attitude, e.g., behavioral intention, previous behavior, and habit, may under some conditions better predict behavior. Also, a viable alternative to attitude testing may be direct appraisal of some science classroom behaviors through ethnomethodology.

  14. Attachment and coercive sexual behavior. (United States)

    Smallbone, S W; Dadds, M R


    This study examined the relationships between childhood attachment and coercive sexual behavior. One hundred sixty-two male undergraduate students completed self-report measures of childhood maternal attachment, childhood paternal attachment, adult attachment, antisociality, aggression, and coercive sexual behavior. As predicted, insecure childhood attachment, especially insecure paternal attachment, was associated with antisociality, aggression, and coercive sexual behavior. Moreover, childhood attachment independently predicted coercive sexual behavior after antisociality and aggression were statistically controlled. The hypothesis that paternal avoidant attachment would predict coercive sexual behavior independently of its relationship with aggression and antisociality was also supported. Posthoc analysis indicated that maternal anxious attachment was associated with antisociality and that paternal avoidant attachment was associated with both antisociality and coercive sexual behavior. These results are consistent with criminological and psychological research linking adverse early family experiences with offending and lend support to an attachment-theoretical framework for understanding offending behavior in general and sexual offending behavior in particular.

  3. Using the theory of planned behavior to predict gambling behavior. (United States)

    Martin, Ryan J; Usdan, Stuart; Nelson, Sarah; Umstattd, M Renee; Laplante, Debi; Perko, Mike; Shaffer, Howard


    Gambling is an important public health concern. To better understand gambling behavior, we conducted a classroom-based survey that assessed the role of the theory of planned behavior (TPB; i.e., intentions, subjective norms, perceived behavioral control, and attitudes) in past-year gambling and gambling frequency among college students. Results from this research support the utility of the TPB to explain gambling behavior in this population. Specifically, in TPB models to predict gambling behavior, friend and family subjective norms and perceived behavioral control predicted past-year gambling, and friend and family subjective norms, attitudes, and perceived behavioral control predicted gambling frequency. Intention to gamble mediated these relationships. These findings suggest that college-based responsible gambling efforts should consider targeting misperceptions of approval regarding gambling behavior (i.e., subjective norms), personal approval of gambling behavior (i.e., attitudes), and perceived behavioral control to better manage gambling behavior in various situations.

  4. Entrepreneurial Behavior and Innovative Behavior: A Conceptual Clarification

    Directory of Open Access Journals (Sweden)

    Muhammad Taufiq Amir


    Full Text Available This paper represents one effort to systematize the use of terminology of entrepreneurial behavior and innovative behavior and to clarify how they relate each other. A clearly stated set of relationship and dynamics on these two concepts is necessary for scientific understanding, explanation and prediction. An agreed-upon relationship between entrepreneurial behavior and innovative behavior makes it easier for investigators to build on each other’s work, and for practitioners to decide whether research finding are applicable to them. Author first reviews some of the existing definitions on entrepreneurial behavior and innovative behavior and illustrates how they are mutually explaining and overlapping. Various terms used to describe the phenomena of interest are clarified. Endorsing, refining, and shepherding entrepreneurial opportunities are more related to idea generation phase of innovative behavior. While the other behaviors, identifying, acquiring and deploying resources needed to pursue entrepreneurial opportunities are more related to idea implementation phase of innovative behavior. Using the theory of socio-cognitive approach, pattern recognition and regulatory focus, the study details the discussion and concludes the overlap between entrepreneurial behavior and the innovative behavior.

    The connection, or bridge, between applied and basic behavior analysis has been long-established (Hake, 1982; Mace & Critchfield, 2010). In this article, we describe how clinical decisions can be based more directly on behavioral processes and how basing clinical procedures on behavioral processes can lead to improved clinical outcomes. As a case in point, we describe how applied behavior analyses of maintenance, and specifically the long-term maintenance of treatment effects related to problem behavior, can be adjusted and potentially enhanced by basing treatment on Behavioral Momentum Theory. We provide a brief review of the literature including descriptions of two translational studies that proposed changes in how differential reinforcement of alternative behavior treatments are conducted based on Behavioral Momentum Theory. We then describe current clinical examples of how these translations are continuing to impact the definitions, designs, analyses, and treatment procedures used in our clinical practice.

    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.

  10. Academic dishonesty and unprofessional behavior. (United States)

    Aaron, Laura; Simmons, Pamela; Graham-Webb, Diane


    To investigate differences in radiologic science student and faculty perceptions of academic dishonesty and unprofessional behavior. Radiologic science faculty and students were questioned about their perceptions of academic dishonesty and unprofessional behavior using ethical scenarios in an electronic survey format. Significant differences occurred between faculty and student values regarding the seriousness of cheating and unprofessional behaviors. Faculty viewed cheating and unprofessional behaviors as more serious than students. Faculty and student self-reports of cheating behavior demonstrated no significant differences; however, significant differences existed in self-reported incidences of unprofessional behavior. Faculty and students differed in their values and participation related to cheating and unprofessional behaviors. Efforts should be directed toward bridging the gap between faculty and student perceptions. ©2011 by the American Society of Radiologic Technologists.

  11. Challenging behavior: Behavioral phenotypes of some genetic syndromes

    Directory of Open Access Journals (Sweden)

    Buha Nataša


    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

  12. [Terrorism and human behavior]. (United States)

    Leistedt, S J


    Theories of religion are essential for understanding current trends in terrorist activities. The aim of this work is to clarify religion's role in facilitating terror and outline in parallel with recent theoretical developments on terrorism and human behaviour. Several databases were used such as PubCentral, Scopus, Medline and Science Direct. The search terms "terrorism", "social psychology", "religion", "evolution", and "cognition" were used to identify relevant studies in the databases. This work examines, in a multidimensional way, how terrorists employ these features of religion to achieve their goals. In the same way, it describes how terrorists use rituals to conditionally associate emotions with sanctified symbols that are emotionally evocative and motivationally powerful, fostering group solidarity, trust, and cooperation. Religious beliefs, including promised rewards in the afterlife, further serve to facilitate cooperation by altering the perceived payoffs of costly actions, including suicide bombing. The adolescent pattern of brain development is unique, and young adulthood presents an ideal developmental stage to attract recruits and enlist them in high-risk behaviors. This work offers insights, based on this translational analysis, concerning the links between religion, terrorism and human behavior. Copyright © 2017 L'Encéphale, Paris.

  13. Young Adult Smoking Behavior (United States)

    Ling, Pamela M.; Neilands, Torsten B.; Glantz, Stanton A.


    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

    Pantoja, Carlos; Hoagland, Adam; Carroll, Elizabeth; Schoppik, David; Isacoff, Ehud Y


    The objective of this protocol is to provide a detailed description for the construction and use of a behavioral apparatus, the zBox, for high-throughput behavioral measurements in larval zebrafish ( Danio rerio ). The zBox is used to measure behavior in multiple individuals simultaneously. Individual fish are housed in wells of multi-well plates and receive acoustic/vibration stimuli with simultaneous recording of behavior. Automated analysis of behavioral movies is performed with MATLAB scripts. This protocol was adapted from two of our previously published papers (Levitz et al. , 2013; Pantoja et al. , 2016). The zBox provides an easy to setup flexible platform for behavioral experiments in zebrafish larvae.

    Shimp, Charles P.


    A case history illustrates how one research program in the experimental analysis of behavior evolved somewhat differently from the modal research program represented in this journal. A chief issue that seems to be responsible for this difference is the role attributed to theory in behavioral research: Skinner's views on the nature and function of theory and on the nature of observation combine to produce a certain kind of picture of behavior. The classic conception of reinforcement contingenc...

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.

  20. Explaining Moral Behavior. (United States)

    Osman, Magda; Wiegmann, Alex


    In this review we make a simple theoretical argument which is that for theory development, computational modeling, and general frameworks for understanding moral psychology researchers should build on domain-general principles from reasoning, judgment, and decision-making research. Our approach is radical with respect to typical models that exist in moral psychology that tend to propose complex innate moral grammars and even evolutionarily guided moral principles. In support of our argument we show that by using a simple value-based decision model we can capture a range of core moral behaviors. Crucially, the argument we propose is that moral situations per se do not require anything specialized or different from other situations in which we have to make decisions, inferences, and judgments in order to figure out how to act.

  1. Occupational medicine. Organizational behavior. (United States)

    Fallon, L F


    Work flow and the administrative processes by which it is controlled are fundamental in shaping the realities of the organization as a system of relationships. Organization is technology in the broadest sense: processes, procedures, policies, controls, formal authority structures, and techniques. Among groups or organizations, it is unusual for changes in sentiment to precede action or organizational rearrangements. Technology and structure must be changed first. This chapter has outlined organizational theory and structures. The components of each have been examined and potential causes of problems identified. Much space has been devoted to understanding group dynamics and behavior. In addition to understanding one's subordinates and peers, the effective manager understands the organizational forces that exist in the workplace. A willingness to listen, communicate, innovate and lead should result in both effectiveness and rewarding experiences for a manager.

  2. Intestinal Barrier and Behavior. (United States)

    Julio-Pieper, M; Bravo, J A


    The intestinal barrier function contributes to gut homeostasis by modulating absorption of water, electrolytes, and nutrients from the lumen into the circulation while restricting the passage of noxious luminal substances and microorganisms. Chronic conditions such as rheumatoid arthritis, inflammatory bowel disease, and celiac disease are associated to intestinal barrier dysfunction. Here, the hypothesis is that a leaky intestinal wall allowing for indiscriminate passage of intraluminal compounds to the vascular compartment could in turn lead to systemic inflammation. An increasing number of studies are now investigating the association between gut permeability and CNS disorders, under the premise that translocation of intestinal luminal contents could affect CNS function, either directly or indirectly. Still, it is unknown whether disruption of intestinal barrier is a causative agent or a consequence in these situations. Here, we discuss the latest evidence pointing to an association between increased gut permeability and disrupted behavioral responses. © 2016 Elsevier Inc. All rights reserved.

  3. Neuropeptides, Microbiota, and Behavior. (United States)

    Holzer, P


    The gut microbiota and the brain interact with each other through multiple bidirectional signaling pathways in which neuropeptides and neuroactive peptide messengers play potentially important mediator roles. Currently, six particular modes of a neuropeptide link are emerging. (i) Neuropeptides and neurotransmitters contribute to the mutual microbiota-host interaction. (ii) The synthesis of neuroactive peptides is influenced by microbial control of the availability of amino acids. (iii) The activity of neuropeptides is tempered by microbiota-dependent autoantibodies. (iv) Peptide signaling between periphery and brain is modified by a regulatory action of the gut microbiota on the blood-brain barrier. (v) Within the brain, gut hormones released under the influence of the gut microbiota turn into neuropeptides that regulate multiple aspects of brain activity. (vi) Cerebral neuropeptides participate in the molecular, behavioral, and autonomic alterations which the brain undergoes in response to signals from the gut microbiota. © 2016 Elsevier Inc.

    There have not been any population-based surveys in Germany to date on the frequency of various types of sexual behavior. The topic is of interdisciplinary interest, particularly with respect to the prevention and treatment of sexually transmitted infections. Within the context of a survey that dealt with multiple topics, information was obtained from 2524 persons about their sexual orientation, sexual practices, sexual contacts outside relationships, and contraception. Most of the participating women (82%) and men (86%) described themselves as heterosexual. Most respondents (88%) said they had engaged in vaginal intercourse at least once, and approximately half said they had engaged in oral intercourse at least once (either actively or passively). 4% of the men and 17% of the women said they had been the receptive partner in anal intercourse at least once. 5% of the respondents said they had had unprotected sexual intercourse outside their primary partnership on a single occasion, and 8% said they had done so more than once; only 2% of these persons said they always used a condom during sexual intercourse with their primary partner. Among persons reporting unprotected intercourse outside their primary partnership, 25% said they had undergone a medical examination afterward because of concern about a possible sexually transmitted infection. Among some groups of persons, routine sexual-medicine examinations may help contain the spread of sexually transmitted infections. One component of such examinations should be sensitive questioning about the types of sexual behavior that are associated with a high risk of infection. Information should be provided about the potential modes of transmission, including unprotected vaginal, oral, and anal intercourse outside the primary partnership.

  6. Behavior genetics: Bees as model

    International Nuclear Information System (INIS)

    Nates Parra, Guiomar


    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.

    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 (non-arbitrariness)....

  11. Fracture, aging and disease in bone

    Energy Technology Data Exchange (ETDEWEB)

    Ager, J.W.; Balooch, G.; Ritchie, R.O.


    From a public health perspective, developing a detailed mechanistic understanding of the well-known increase in fracture risk of human bone with age is essential. This also represents a challenge from materials science and fracture mechanics viewpoints. Bone has a complex, hierarchical structure with characteristic features ranging from nanometer to macroscopic dimensions; it is therefore significantly more complex than most engineering materials. Nevertheless, by examining the micro-/nano-structural changes accompanying the process of aging using appropriate multiscale experimental methods and relating them to fracture mechanics data, it is possible to obtain a quantitative picture of how bone resists fracture. As human cortical bone exhibits rising ex vivo crack-growth resistance with crack extension, its fracture toughness must be evaluated in terms of resistance-curve (R-curve) behavior. While the crack initiation toughness declines with age, the more striking finding is that the crack-growth toughness declines even more significantly and is essentially absent in bone from donors exceeding 85 years in age. To explain such an age-induced deterioration in the toughness of bone, we evaluate its fracture properties at multiple length scales, specifically at the molecular and nanodimensions using pico-force atomic-force microscopy, nanoindentation and vibrational spectroscopies, at the microscale using electron microscopy and hard/soft x-ray computed tomography, and at the macroscale using R-curve measurements. We show that the reduction in crack-growth toughness is associated primarily with a degradation in the degree of extrinsic toughening, in particular involving crack bridging, and that this occurs at relatively coarse size-scales in the range of tens to hundreds of micrometers. Finally, we briefly describe how specific clinical treatments, e.g., with steroid hormones to treat various inflammatory conditions, can prematurely damage bone, thereby reducing its

    Full Text Available The way consumers think about the products they will buy determines their buying behavior. The decision to buy a particular product is obviously in accordance with the buyer’s attitude. The buyers will also feel more comfortable if their behavior meets with the approval and expectations of the people close to them. While the development of a certain attitude has no effect on subjective judgment, the effect of compromise is likely to make a contribution to its development. Since it is still unclear, this study’s main purposed is to clarify this. In addition, while an attitude is theorized as being a predictor of behavior, through behavioral intention, the study’s secondary purpose is to boost the earlier findings. Likewise, in accordance with the theory of planned behavior, the study will also examine the other predictors of behavioral intention, in relation to the behavioral intention itself. A sample consisting of a 100 respondents was compiled by using the convenience and judgment technique. The data were analyzed using Amos 16.0 and SPSS 16.0. As expected, the compromise effect had a significant influence on whether the customers’ attitude or the subjective norm was the main determinant. Likewise, the customers’ attitude, the subjective norm and perceived behavioral control were confirmed as good predictors of customers’ behavioral intentions.

  15. Effective strategies for behavior change. (United States)

    Coleman, Mary Thoesen; Pasternak, Ryan H


    Strategies that are most effective in both prevention and management of chronic disease consider factors such as age, ethnicity, community, and technology. Most behavioral change strategies derive their components from application of the health belief model, the theory of reasoned action/theory of planned behavior, transtheoretical model, and social cognitive theory. Many tools such as the readiness ruler and personalized action plan form are available to assist health care teams to facilitate healthy behavior change. Primary care providers can support behavior changes by providing venues for peer interventions and family meetings and by making new partnerships with community organizations.

  1. [Practice of Behavioral Activation in Cognitive-behavioral Therapy]. (United States)

    Kitagawa, Nobuki


    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.

  2. Behavior of pharyngocutaneous fistula

    Reynaldo Gonzalez, Maria de los Angeles; Trinchet Soler, Rafael; Perez Fernandez, Julia; Alvarez Borges, Francisco Emilio


    INTRODUCTION. The pharyngocutaneous fistula is clinically detected by appearance of saliva together with deglutition. It is more frequent in postoperative period of total laryngectomies and may to appear in a spontaneous way by dehiscence of pharyngeal suture provoked by deglutition movements of patient or to go with a infection or necrosis. METHODS. A descriptive and bilateral study was conducted on the behavior of pharyngocutaneous fistulas in Cervicofacial Oncology Surgery Service of ''Vladimir Ilich Lenin'' University Hospital in Holguin province. Study sample included all patients operated on by total laryngectomy from 2003 to 2008. There was a total 158 patients and all underwent a manual closure of hypofarynx. RESULTS. Fistulas were present in the 5,6% of cases. The 77,7% of patients had underwent radiotherapy before surgery and the 66,4% of them underwent tracheostomies at surgical operation. In all patients operated on by pharyngotome there was postsurgical sepsis and feeding was started at 10 and 12 days in the 88,4% of cases. CONCLUSIONS. The wide predominance of male patients is directly related to usual toxic habits in this sex. Presurgical tracheostomy is accepted by surgeons as a risk factor for development of fistula, but in present paper wasn't significant. Onset of oral feeding in patients presenting with layngectomies must to fluctuate between 10 and 14 days, never before, but there isn't a hypopharynx healing allowing the foods passage. Also, so it is possible to avoid the appearance of complications like the pharyngocutaneous fistulas. (author)

The family approach is to search out a guilt of members to understand family dynamics and enable young people to emancipate themselves from the family model. The social environment contributes to the marginalization of drug users "pathologizing" his conduct. Offer help without preconditions and a relationship based on a therapeutic alliance can contribute decisively to the recovery of an addict. The prison is a place of initiation of use and consumption of psychoactive substances despite the offer of specialized treatment. Measures of risk reduction of HCV/HIV infection and alternatives to incarceration should complete it. At workplace, consumption can be considered as a mean of doping to be more "efficient", but also as an attempt to withstand the stresses and changes in working conditions in the context of individualization and a loss of marks related to the new way of organizing work.

    Full Text Available The size of the elderly population is expected to increase dramatically in the next decades worldwide, also in Turkey. In accordance with these demographic changes, psychiatric disorders in late life, including suicide becomes much important. Elderly suicide is a very serious public health problem. Suicide rates in both males and females generally increase with age. However, the pattern is different in every nation. Suicidal behaviour in old age exists as a spectrum ranging from death wishes to completed suicide. Risk factors for suicide in old age are male sex, lower socioeconomic status, social isolation, having personality traits like hopelessness and dependency on others etc., the presence of psychiatric and physical disorders and previous suicidal behaviour. The most common cause for elderly suicide, as for all suicides, is untreated depression. Thus, elderly depression needs to be recognized and treated. The treatment of depressive disorder and other psychiatric diorders in late life, counselling in crisis situations and prevention of social isolation in elderly people are the major points for the prevention of suicide in old age. In this review article is to investigate the relationship between elderly and suicidal behavior. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2014; 6(3.000: 294-309

  8. Behavioral methods in cannabinoid research. (United States)

    Fride, Ester; Perchuk, Alex; Hall, F Scott; Uhl, George R; Onaivi, Emmanuel S


    In the absence of any specific behavioral assay for cannabinoids or endocannabinoids, a cannabinoid-induced profile in a series of four in vivo assays in mice is most commonly used to assess a specific cannabinoid activity at the behavioral level. Thus, when a given compound produces motor depression in an open field, catalepsy on an elevated ring, analgesia on a hot plate, as well as hypothermia, cannabinoid CB1 receptor activation is assumed, although exceptions are possible. The full cannabinoid profile, however, includes for example ataxia in dogs and discrimination learning in rats. In view of (1) the addictive/reward potential of cannabis and the cannabinoids and (2) the multiple roles of the endocannabinoid physiological control system (EPCS) in behavioral functions, including memory, emotionality, and feeding, a number of behavioral techniques have been used to assess the effects of cannabinoids in these functions. In this chapter we will describe the tetrad of cannabinoid-induced effects as well as a series of behavioral assays used in the behavioral pharmacology of marijuana-cannabinoid research. Since the EPCS plays an important role in the developing organism, methods used in the assessment of physical and behavioral development will also be discussed. The techniques include the tetrad, drug discrimination, self-stimulation and self-administration, conditioned place preference/aversion, the plus-maze, chronic mild stress (CMS), ultrasonic vocalizations, cognitive behaviors, and developmental assessment in mouse (and rat) pups.

    Full Text Available Complaining is one form of communication for consumers to express their dissatisfaction. Understanding the consumer complaint behavior is an important thing for businesses; however, it is not easy to do. The initial step in understanding this behavior of consumer complaints is to map consumers based on their behavior of complaints and analyze the factors that influence this. This study examines the complaint behavior of consumers in Cibubur who have experienced dissatisfaction with a product.  The objectives of this study are to map the consumer complaint behavior and identify its relationship with various factors such as consumer demographics, personality, attitude to businesses, attribution of the causes of dissatisfaction, and product attributes. A crosstab descriptive analysis method was used to map the consumers, while the Pearson correlation analysis methods was used to analyze consumer complaint behavioral relationships with various factors. The results of this study indicated that consumers in Cibubur based on their complaint behavior are classified into four groups: passive, voicers, irates and activist. The passive consumers dominate the category with a percentage of 49%.  The voicers, irates, and activist belong to the complaining type and are dominated by young women, with high levels of education and income. Keywords: consumer complaint behavior, product, crosstab, pearson correlation

  3. Information: theory, brain, and behavior. (United States)

    Jensen, Greg; Ward, Ryan D; Balsam, Peter D


    In the 65 years since its formal specification, information theory has become an established statistical paradigm, providing powerful tools for quantifying probabilistic relationships. Behavior analysis has begun to adopt these tools as a novel means of measuring the interrelations between behavior, stimuli, and contingent outcomes. This approach holds great promise for making more precise determinations about the causes of behavior and the forms in which conditioning may be encoded by organisms. In addition to providing an introduction to the basics of information theory, we review some of the ways that information theory has informed the studies of Pavlovian conditioning, operant conditioning, and behavioral neuroscience. In addition to enriching each of these empirical domains, information theory has the potential to act as a common statistical framework by which results from different domains may be integrated, compared, and ultimately unified. © Society for the Experimental Analysis of Behavior.

  4. Quantifying Aggressive Behavior in Zebrafish. (United States)

    Teles, Magda C; Oliveira, Rui F


    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.

  5. Behavioral variability in an evolutionary theory of behavior dynamics. (United States)

    Popa, Andrei; McDowell, J J


    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. © 2016 Society for the Experimental Analysis of Behavior.

  6. Pollen Processing Behavior of Heliconius Butterflies: A Derived Grooming Behavior (United States)

    Hikl, Anna-Laetitia; Krenn, Harald W.


    Pollen feeding behaviors Heliconius and Laparus (Lepidoptera: Nymphalidae) represent a key innovation that has shaped other life history traits of these neotropical butterflies. Although all flower visiting Lepidoptera regularly come in contact with pollen, only Heliconius and Laparus butterflies actively collect pollen with the proboscis and subsequently take up nutrients from the pollen grains. This study focused on the behavior of pollen processing and compared the movement patterns with proboscis grooming behavior in various nymphalid butterflies using video analysis. The proboscis movements of pollen processing behavior consisted of a lengthy series of repeated coiling and uncoiling movements in a loosely coiled proboscis position combined with up and down movements and the release of saliva. The proboscis-grooming behavior was triggered by contamination of the proboscis in both pollen feeding and non-pollen feeding nymphalid butterflies. Proboscis grooming movements included interrupted series of coiling and uncoiling movements, characteristic sideways movements, proboscis lifting, and occasionally full extension of the proboscis. Discharge of saliva was more pronounced in pollen feeding species than in non-pollen feeding butterfly species. We conclude that the pollen processing behavior of Heliconius and Laparus is a modified proboscis grooming behavior that originally served to clean the proboscis after contamination with particles.

  11. Behavioral dimensions of food security. (United States)

    Timmer, C Peter


    The empirical regularities of behavioral economics, especially loss aversion, time inconsistency, other-regarding preferences, herd behavior, and framing of decisions, present significant challenges to traditional approaches to food security. The formation of price expectations, hoarding behavior, and welfare losses from highly unstable food prices all depends on these behavioral regularities. At least when they are driven by speculative bubbles, market prices for food staples (and especially for rice, the staple food of over 2 billion people) often lose their efficiency properties and the normative implications assigned by trade theory. Theoretical objections to government efforts to stabilize food prices, thus, have reduced saliency, although operational, financing, and implementation problems remain important, even critical. The experience of many Asian governments in stabilizing their rice prices over the past half century is drawn on in this paper to illuminate both the political mandates stemming from behavioral responses of citizens and operational problems facing efforts to stabilize food prices. Despite the theoretical problems with free markets, the institutional role of markets in economic development remains. All policy instruments must operate compatibly with prices in markets. During policy design, especially for policies designed to alter market prices, incentive structures need to be compatible with respect to both government capacity (bureaucratic and budgetary) and empirical behavior on the part of market participants who will respond to planned policy changes. A new theoretical underpinning to political economy analysis is needed that incorporates this behavioral perspective, with psychology, sociology, and anthropology all likely to make significant contributions.

    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

  14. Financial incentives for healthy behavior: ethical safeguards for behavioral economics. (United States)

    Lunze, Karsten; Paasche-Orlow, Michael K


    Economic incentives to promote healthy behavior are becoming increasingly common and have been suggested as an approach to decreasing healthcare costs. Ethical concerns about programs with such incentives are that they may contribute to inequities, be coercive, interfere with therapeutic relationships, undermine personal responsibility for health, and decrease social solidarity. Additionally, they may be a source of stigma or discrimination, promote dependence, and be unfair for those already engaged in targeted health behaviors or those who cannot fulfill the incentivized behaviors. Incentive programs need to incorporate appropriate safeguards to monitor these risks and support fairness in offering economic incentives to promote healthy behavior.

  16. Behavioral self-concept as predictor of teen drinking behaviors. (United States)

    Dudovitz, Rebecca N; Li, Ning; Chung, Paul J


    Adolescence is a critical developmental period for self-concept (role identity). Cross-sectional studies link self-concept's behavioral conduct domain (whether teens perceive themselves as delinquent) with adolescent substance use. If self-concept actually drives substance use, then it may be an important target for intervention. In this study, we used longitudinal data from 1 school year to examine whether behavioral self-concept predicts teen drinking behaviors or vice versa. A total of 291 students from a large, predominantly Latino public high school completed a confidential computerized survey in the fall and spring of their 9th grade year. Survey measures included the frequency of alcohol use, binge drinking and at-school alcohol use in the previous 30 days; and the Harter Self-Perception Profile for Adolescents behavioral conduct subscale. Multiple regressions were performed to test whether fall self-concept predicted the frequency and type of spring drinking behavior, and whether the frequency and type of fall drinking predicted spring self-concept. Fall behavioral self-concept predicted both the frequency and type of spring drinking. Students with low versus high fall self-concept had a predicted probability of 31% versus 20% for any drinking, 20% versus 8% for binge drinking and 14% versus 4% for at-school drinking in the spring. However, neither the frequency nor the type of fall drinking significantly predicted spring self-concept. Low behavioral self-concept may precede or perhaps even drive adolescent drinking. If these results are confirmed, then prevention efforts might be enhanced by targeting high-risk teens for interventions that help develop a healthy behavioral self-concept.

  17. Terrorism and the behavioral sciences. (United States)

    Schouten, Ronald


    Terrorism has existed for millennia and is a phenomenon well-known to many parts of the world. Americans were forced to recognize this phenomenon, and our vulnerability to it, by two sets of events in 2001: the attacks on New York City and Washington, DC, and the anthrax mailings that followed shortly thereafter. Psychiatry, psychology, and other behavioral and social sciences have been looked to for assistance in collecting and analyzing intelligence data, understanding terrorism, and developing strategies to combat terrorism. In addition to reviewing areas in which the behavioral sciences have made contributions in addressing this problem, this article discusses the developing roles for behavioral scientists in this field.

    Directory of Open Access Journals (Sweden)

    Güler Demir


    Full Text Available The main purpose of this book is to develop a theoretical framework for the investigation of human information behavior within a multidisciplinary approach. Information behavior is not only instinctive with its social/cultural and cognitive dimensions, but is also a type of intelligence and a universal and biologically primary skill belonging to all of the people. It is thought that further researches are needed in order to clarify the process of information behavior which is such a complex process that cannot be fully understood only by contemporary and/or limited dimensions.

    Full Text Available Research was reviewed on whether self-report measures of religiosity were a protective factor against suicidal behaviors. It was found that scores on Francis’s measure of religiosity was negatively associated with non-lethal suicidal behavior (ideation and attempts, a protective effect. Similarly, it was found that intrinsic religiosity (but not extrinsic religiosity was negatively associated with non-lethal suicidal behaviors. However, these associations were weak. Research is needed on the issue whether counselors can use their patients’ religiosity to reduce the risk of dying by suicide.

  20. Brain and Behavior: a Review

    Directory of Open Access Journals (Sweden)

    Rivera Urbina, Guadalupe N.


    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.

    Junkers, G


    Behavior therapy has up to now, only been applied to a limited degree to elderly people. Operant learning paradigma receive special meaning within the framework of intervention as well as theoretical explanation. Publications will be presented for the areas of social behavior, self care, motoric ability etc. according to their different techniques. It is remarkable that interest has only focused institutionalized elderly people with a high degree of incapacitation. In the following discussion the necessity for stronger consideration of the newer behavioral approach as well the latest developments in gerontology will be made clear.

    Brad T Klontz


    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.

  5. Individualized Behavioral Health Monitoring Tool (United States)

    Mollicone, Daniel


    Behavioral health risks during long-duration space exploration missions are among the most difficult to predict, detect, and mitigate. Given the anticipated extended duration of future missions and their isolated, extreme, and confined environments, there is the possibility that behavior conditions and mental disorders will develop among astronaut crew. Pulsar Informatics, Inc., has developed a health monitoring tool that provides a means to detect and address behavioral disorders and mental conditions at an early stage. The tool integrates all available behavioral measures collected during a mission to identify possible health indicator warning signs within the context of quantitatively tracked mission stressors. It is unobtrusive and requires minimal crew time and effort to train and utilize. The monitoring tool can be deployed in space analog environments for validation testing and ultimate deployment in long-duration space exploration missions.

    The emerging Knowledge Governance Approach asserts the need to build microfoundations grounded in individual action. Toward this goal, using the Theory of Planned Behavior, we aim to explain individual knowledge sharing behavior as being determined by the intention to share knowledge and its...... antecedents: attitude toward knowledge sharing, subjective norms, and perceived behavioral control. In addition, we consider managerial interventions (governance mechanisms) that managers can employ to influence the identified antecedents and thereby govern individual knowledge sharing behavior. We test...... the model arrived at on a dataset collected among individuals engaged in knowledge sharing in two competing firms. Results of the LISREL analysis show that the use of rewards affects attitudes toward knowledge sharing negatively, while the use of reciprocal schemes and communication mechanisms have...

To accomplish this, we developed a network of behaviors that communicate through the passing of rings, data structures that are similar in form to the sonar data itself and express the decisions of each behavior. Through the use of these rings, behaviors can moderate each other, conflicting impulses can be mediated, and designers can easily connect modules to create complex emergent navigational techniques. We discuss the development of a number of these modules and their successful use as a navigation system in the Trinity omnidirectional robot.

  8. [Behavioral impairments in Parkinson's disease]. (United States)

    Kashihara, Kenichi


    Behavioral impairments in parkinsonian patients include agitation, hypersexuality, stereotypic movement, pathological gambling, abuse of antiparkinsonian drugs, REM sleep behavioral disorder, and restless legs syndrome. Dementia, psychoses, and emotional disorders, such as depression and anxiety/panic disorder, also impair behavior. Symptoms may be produced by dysfunction of the central nervous system, medication, and/or the psychosocial problems associated with Parkinson's disease. Treatment therefore should be based on the cause of the symptoms seen. In some cases, the reduction or change of antiparkinsonian drugs, or both, may be effective. Treatment of the motor symptoms of Parkinson's disease, including motor fluctuations, may reduce the risk of panic attacks being evoked in the 'off' period. Use of antidepressants, sedatives, and neuroleptics may often be effective. Physicians should identify the causes of the symptoms of behavioral impairment and select appropriate treatments.

  9. Addictive behaviors and Parkinson's disease. (United States)

    Witjas, T; Eusebio, A; Fluchère, F; Azulay, J-P


    In Parkinson's disease, the degeneration of the dopaminergic system and the longstanding exposure to dopamine replacement therapy (DRT) may cause, in a group of vulnerable patients, dysregulation of the brain reward system. These patients develop DRT-related compulsions, which include addiction to levodopa or dopamine dysregulation syndrome (DDS), punding, and impulse control disorders (ICDs). ICDs or behavioral addiction reported in Parkinson's disease include pathological gambling, hypersexuality, compulsive buying and binge eating. Although the underlying pathophysiology is still poorly understood, these behaviors are linked by their reward-based and repetitive nature. Such behaviors may result in devastating psychosocial impairment for the patients and are often hidden. The recognition of these behaviors is important and allows a better clinical management. Although the limited data do not permit particular therapeutic strategies, some approaches are worth considering: DRT reduction, trials of non-dopaminergic medications and subthalamic chronic stimulation.

  10. Behavioral syndromes in Alzheimer's disease. (United States)

    Devanand, D P; Brockington, C D; Moody, B J; Brown, R P; Mayeux, R; Endicott, J; Sackeim, H A


    The Behavioral Syndromes Scale for Dementia (BSSD) is a new instrument that showed strong internal consistency and interrater reliability in an outpatient sample of 106 patients with probable Alzheimer's disease. Factor analysis provided support for a priori symptom groupings, particularly the syndromes of disinhibition and apathy-indifference. Dependency (87%), denial of illness (63%), and motor agitation (55%) were common, while sexual disinhibition (2.9%) and self-destructive behaviors (2.9%) were rare. Virtually all symptoms were predominantly minimal to mild in severity. Patients with longer illness duration were more apathetic. Disinhibited behaviors and apathy-indifference increased with greater severity of dementia. Catastrophic reactions, aggression, and agitation were associated with greater functional impairment. There was great heterogeneity in symptom presentation. In Alzheimer's disease, several behavioral changes might be direct manifestations of underlying brain pathology, rather than being solely secondary to cognitive impairment.

  17. Health behaviors of postmenopausal women

    Directory of Open Access Journals (Sweden)

    Maria Jasińska


    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

    A recent trend in programming language research is to use behav- ioral type theory to ensure various correctness properties of large- scale, communication-intensive systems. Behavioral types encompass concepts such as interfaces, communication protocols, contracts, and choreography. The successful application of behavioral types requires a solid understanding of several practical aspects, from their represen- tation in a concrete programming language, to their integration with other programmi...

  19. Hydrologic behavior of fracture networks

    International Nuclear Information System (INIS)

    Long, J.C.S.; Endo, H.K.; Karasaki, K.; Pyrak, L.; MacLean, P.; Witherspoon, P.A.


    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

  20. Walking behavior in technicolored GUTs

    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.

    Full Text Available Suicide associated mortality rates are notable for eating disorders. Crude mortality rate associated with suicide, varies between 0% and 5.3% in patients with eating disorders. Prominent risk factors for suicidal behavior among these patients are subtype of the eating disorders, comorbid psychiatric diagnosis (e.g. depression, alcohol and substance abuse, personality disorders, ultrarapid drug metabolism, history of childhood abuse and particular family dynamics. In this article, suicidal behavior and associated factors in eating disorders are briefly reviewed.

  3. Behavioral assays in environmental toxicology

    Weiss, B.


    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.

    Full Text Available On the sample by 121 perspective young athletes was carried out the researching in the aim to establish the behavior style of coaches. The relevant information was obtained through the validated questionnaires of Chelladura and Saleha (1980. The questionnaire contains 40 questions which directly determine 5 behavior styles of coaches. All questions possess the scale by 5 levels with possible statements: (always, often, periodically, rarely and never. The true answer is only one statement on one question. It is word about five degrees 'Likert's scale'. It was carried out extensive and complex statistics processing of date, where the input qualitative categorical variables were transformed into quantitative. In the next step, transformed categorical variables were exposed in classical and neoclassical statistical methodology. On the base of exact indications which were obtained by using relevant invariant and multivariate statistical methods and tests, dominant behavior style of coaches is 'Instructive'. This behavior style of coach is the most desirable. According to this researching at the last position is behavior style which is the autocratically and it is also at the same time the least desirable. The results of Analysis of variance (ANOVA and Canonic discriminative analysis show the general statistical significant difference in the representation of the behavior styles. Instructive and Autocratic behavior style of coach mostly influences on the total (general discrimination i.e. difference. For above mentioned styles, it could be said that they are paradigm of contrasts in every way. Values of Tukey - HSD test explicitly shows that there are not statistical significant difference between Instructive Style and style Awarded - Feedback as well as between Democratically and style of Social Support. The other combinations i.e. couples of behavior styles are statistical significantly different.

  6. The primatologist as a behavioral engineer. (United States)

    Martin, Allison L


    The field of primate behavior management has had only limited success in preventing and treating abnormal behaviors, such as stereotypy and self-injury, in captive non-human primates (NHP). In contrast, applied behavior analysts have had great success in treating similar topographies of behavior in human clinical settings. By adapting and adopting the behavioral principles and methodologies commonly used by applied behavior analysts, primatologists may be able to develop more effective ways to analyze, reduce, and prevent these aberrant behaviors in NHP. This article reviews studies that have used behavior analytic techniques to successfully address problem behaviors in NHP. Additionally, relevant literature from the field of applied behavior analysis is reviewed to illustrate how adopting a theoretical framework that emphasizes the determination of the underlying operant functions of behavior could lead to new behavioral technologies and advance the field of captive primate management.

  8. Relapse prevention for addictive behaviors

    Directory of Open Access Journals (Sweden)

    George William H


    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.

  9. Driving citations and aggressive behavior. (United States)

    Sansone, Randy A; Leung, Justin S; Wiederman, Michael W


    Anger and driving have been examined in a number of studies of aggressive drivers and in drivers with road rage using various psychological and environmental study variables. However, we are not aware of any study that has examined the number of driving citations (an indication of problematic driving) and various forms of anger not related to driving. Using a cross-sectional approach in a consecutive sample of 331 respondents (68% female), we surveyed participants about the number of past driving citations, not necessarily convictions, and 21 aggressive behaviors using the Aggressive Behavior Questionnaire. The number of driving citations demonstrated a statistically significant correlation with the number of aggressive behaviors in the 21-item Aggressive Behavior Questionnaire. There were no differences between men and women. As for specific aggressive behaviors, the number of driving citations was statistically significantly related to punching a wall when angry, causing and getting into a bar fight, getting into fistfights (not in a bar), causing someone to have an accident, and intentionally running someone off the road. The number of driving citations, an indication of problematic driving, appears to be related to generally aggressive behavior. Findings indicate that if aggression plays a role in problematic driving, it is likely not limited to the road.

  10. Dopamine, behavioral economics, and effort

    Directory of Open Access Journals (Sweden)

    John D Salamone


    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.

  11. Behavioral Targeting—Consumer Tracking (United States)

    Srimani, P. K.; Srinivas, A.


    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.

  12. Animal behavior and animal welfare. (United States)

    Houpt, K A


    The value of behavioral techniques in assessing animal welfare, and in particular assessing the psychological well being of animals, is reviewed. Using cats and horses as examples, 3 behavioral methods are presented: (1) comparison of behavior patterns and time budgets; (2) choice tests; and (3) operant conditioning. The behaviors of intact and declawed cats were compared in order to determine if declawing led to behavioral problems or to a change in personality. Apparently it did not. The behavior of free ranging horses was compared with that of stabled horses. Using two-choice preference tests, the preference of horses for visual contact with other horses and the preference for bedding were determined. Horses show no significant preference for locations from which they can make visual contact with other horses, but they do prefer bedding, especially when lying down. Horses will perform an operant response in order to obtain light in a darkened barn or heat in an outside shed. These same techniques can be used to answer a variety of questions about an animal's motivation for a particular attribute of its environment.

  14. Behavior as a social construction. (United States)

    Shimp, C P.


    Behavior analysis is examined from a social constructionist perspective. Constructionism is first defined and contrasted with a generic positivistic image of science. Behavior analysis, especially the matching law, is then viewed from both perspectives. The actual practice of behavior analysis (as opposed to the philosophy of radical behaviorism) more strongly resembles positivist than constructionist views. This alignment between behavior analysis and positivism emerges more sharply when positivist and constructionist perspectives are compared on the relation between science and music. Charles Rosen has identified how the classical style of musical composition and performance depended on 18th century keyboard technology, and a constructionist view sees the matching law as reflecting mid 20th century technology and culture in much the same way as it sees, say Mozart's 23rd piano concerto, as reflecting late 18th century culture. Behavior analysts, who often behave as though they see the matching law as an objective, impersonal, stable, hard, cold, incontrovertibly true fact, appear more inclined than constructionists to see a fundamental difference between the matching law and Mozart's 23rd piano concerto, to which they would attribute few if any of these characteristics. Possible implications are derived for tolerance in science.

    Street children and youth are at risk of getting engaged in different behaviors including risky sexual behavior, which adversely affects their development and health. The aim of this study was to examine sexual behavior of street children and youth, and the risks and consequences associated with sexual behavior. A pilot study was conducted on a sample of 50 users of the Drop-in Centre for Street Children in Novi Sad, from 10 to 19 years of age. The study was conducted by a psychologist through structured interviews, with prior consent of the adolescent and parent. Among the respondents who were sexually active, 41.2% had had the first sexual intercourse by the age of 12, their median age at that time being 14 years, while the age at the time of the first sexual intercourse is 16 years in the general population of Serbia. The majority of sexually active adolescents had several partners, one male adolescent had sex with a person of the same sex, and one was paid for sex. Very few respondents used a condom. Among 15 male sexually active respondents, three (ages 11, 12 and 14) were forced to have unwanted sexual intercourse, and a quarter of adolescents (three boys and one girl) were forced to do something unwanted during sex. Despite a small and unrepresentative sample, the results of this study indicate serious problems and significant risks associated with sexual behavior of children and young people who live and work in streets. This pilot study suggests that it is necessary to conduct new research on sexual behavior of street children and youth on a representative sample and with appropriate methodology. The results of a new study should be used to plan and carry out appropriate preventive measures regarding sexual behavior of street children.

  19. Understanding behaviors in videos through behavior-specific dictionaries

    Ren, Huamin; Liu, Weifeng; Olsen, Søren Ingvor


    Understanding behaviors is the core of video content analysis, which is highly related to two important applications: abnormal event detection and action recognition. Dictionary learning, as one of the mid-level representations, is an important step to process a video. It has achieved state...... scalability needs: A dictionary aimed at an abnormality detection purpose may misdetect normal behavior, which rarely happens in training datasets even though it may be very common in daily life. In contrast, a dictionary aimed at action recognition may misclassify a newcoming action category as an existing...... action. Therefore, our Behavior-Specific Dictionaries (BSDs) are constructed to solve these two applications through a unified framework. To the best of our knowledge, this is the first generalized dictionary algorithm that successfully handle with action recognition and abnormality detection...

  20. [Dialectical behavior therapy approaches with disruptive behavior disorders]. (United States)

    Stadler, Christina; Manetsch, Madleina; Vriends, Noortje


    Disruptive behaviour disorders comprise the diagnosis conduct disorder (CD) and in adults the diagnosis antisocial personality disorder (APD). CD is seen as a difficult-to-treat disorder with a high risk for persistent behavioral problems. In addition, CD is seen as the precursor to antisocial personality disorder (Kretschmer et al., 2014). Dialectical behavior therapy (DBT) was originally developed by Marsha Linehan (1991) for the treatment of borderline personality disorder, but because of the core deficits in emotion regulation in disruptive behavior disorders, DBT is also increasingly being recommended for the treatment of CD and APD. This review presents DBT adaptions for the forensic setting and for the treatment of CD/APD. Clinical implications are discussed.

    Eiamsitrakoon, Thanee; Apisarnthanarak, Anucha; Nuallaong, Winitra; Khawcharoenporn, Thana; Mundy, Linda M


    In 2009, the World Health Organization (WHO) recommended "My Five Moments for Hand Hygiene" (5MHH) to optimize hand hygiene (HH). Uptake of these recommendations by healthcare workers (HCWs) remains uncertain. We prospectively observed HCW compliance to 5 MHH. After observations, eligible HCWs who consented to interviews completed surveys on factors associated with HH compliance based on constructs from the transtheoretical model of behavioral change (TTM) and the theory of planned behavior (TPB). Survey results were compared with observed HCW behaviors. There were 968 observations among 123 HCWs, of whom 110 (89.4%) were female and 63 (51.3%) were nurses. The mean HH compliance for all 5 MHH was 23.2% (95% confidence interval [CI], 18.1%-28.3%) by direct observation versus 82.4% (95% CI, 79.9%-84.9%) by self report. The HCW 5 MHH compliance was associated with critical care unit encounters (P commitment.

  4. Behavior model for performance assessment.

    Energy Technology Data Exchange (ETDEWEB)

    Borwn-VanHoozer, S. A.


    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.

    Full Text Available Conceptually, the stock market is strong form efficient in the long term. However, in practice, there are various forms of market anomalies that undermine the accuracy of the efficient market hypothesis. One factor suspected as the cause of market inefficiency is herding behavior. Investors herd when they imitate the actions of other investors. This behavior occurs when there is a continuous interaction among rational investors that prevents them from seeking information about market fundamentals. This study provides new insights by including information asymmetry as a moderating variable. This research examines the phenomenon of herding behavior in the Indonesia Stock Exchange as well as examines directly the effect of information asymmetry on herding behavior. The period of study is 2008 using time series of daily stocks data that actively traded in the capital market. Results of this study find that investor tends to follow market consensus when price changes at the low level, but when there is large price swing market participant acts independently from other investors. Interestingly, this study finds that information asymmetry is a necessary condition for the existence of herding behavior.

  6. Towards Behaviorally Informed Public Interventions

    Directory of Open Access Journals (Sweden)

    Karol Olejniczak


    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.

  7. Behavior model for performance assessment

    International Nuclear Information System (INIS)

    Brown-VanHoozer, S. A.


    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.

  8. Maximization, learning, and economic behavior. (United States)

    Erev, Ido; Roth, Alvin E


    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.

  9. Valuable, but not maximal: it's time behavior therapy attend to its behaviorism. (United States)

    Staats, A W


    The field of behavior therapy is not in touch with itself in terms of its overarching behaviorism. Many erroneously consider its basic behaviorism to have been radical behaviorism and continue to look to develop behavior therapy (including behavior analysis and behavioral assessment) within that framework. But that approach turns out to be much less than maximal because there is a more advanced, better developed behaviorism within which to conduct and project the field. There is much that behavior therapy is not doing in practice and research because it is not making full use of that behaviorism foundation.

  10. Adolescents' Friendships, Academic Achievement, and Risk Behaviors: Same-Behavior and Cross-Behavior Selection and Influence Processes. (United States)

    Gremmen, Mariola C; Berger, Christian; Ryan, Allison M; Steglich, Christian E G; Veenstra, René; Dijkstra, Jan K


    This study examined to what extent adolescents' and their friends' risk behaviors (i.e., delinquency and alcohol use) hinder or promote their academic achievement (grade point average [GPA]), and vice versa. Longitudinal data were used (N = 1,219 seventh- to ninth-grade adolescents; M age  = 13.69). Results showed that risk behaviors negatively affected adolescents' GPA, whereas GPA protected against engaging in risk behaviors. Moreover, adolescents tended to select friends who have similar behaviors and friends' behaviors became more similar over time (same-behavior selection and influence). Furthermore, although same-behavior effects seemed to dominate, evidence was found for some cross-behavior selection effects and a tendency in seventh grade for cross-behavior influence effects. Concluding, it is important to investigate the interplay between different behaviors with longitudinal social network analysis. © 2018 The Authors.

  11. A review of different behavior modification strategies designed to reduce sedentary screen behaviors in children. (United States)

    Steeves, Jeremy A; Thompson, Dixie L; Bassett, David R; Fitzhugh, Eugene C; Raynor, Hollie A


    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.

  12. Pavlov's position toward American behaviorism. (United States)

    Windholz, G


    Pavlov's development of the conditional reflex theory coincided with the rise of American behaviorism. Substituting an objective physiology for a subjective psychology, Pavlov saw in the rise of American behaviorism a clear confirmation of his method and theory. But in the early 1930s, Lashley attacked Pavlov's theory of specific cerebral localization of function, proposing instead the concept of an internal cerebral organization; Guthrie objected to Pavlov's centralist interpretation of conditioning, proposing instead a peripheralist interpretation; while Hull challenged Pavlov's theory of sleep and hypnosis as the manifestations of inhibition. Pavlov replied with critiques of Lashley's, Guthrie's, and Hull's views, and, convinced that Lashley and Guthrie misunderstood his position, repeated his method's and theory's basic propositions. Yet, Pavlov never gave up the expectation that American behaviorism would accept his conditional reflex theory and saw in Hunter's 1932 statements a support of his assumptions.

  13. Frustration behaviors in domestic dogs. (United States)

    Jakovcevic, Adriana; Elgier, Angel M; Mustaca, Alba E; Bentosela, Mariana


    During extinction a previously learned behavior stops being reinforced. In addition to the decrease in the rate of the instrumental response, it produces an aversive emotional state known as frustration. This state can be assimilated with the fear reactions that occur after aversive stimuli are introduced at both the physiological and behavioral levels. This study evaluated frustration reactions of domestic dogs (Canis familiaris) during a communicative situation involving interactions with a human. The task included the reinforcement and extinction of the gaze response toward the experimenter's face when the dogs tried to obtain inaccessible food. The dog's frustration reactions during extinction involved an increase in withdrawal and side orientation to the location of the human as well as lying down, ambulation, sniffing, and vocalizations compared with the last acquisition trial. These results are especially relevant for domestic dog training situations in which the extinction technique is commonly used to discourage undesirable behaviors.

  14. Linking brain, mind and behavior. (United States)

    Makeig, Scott; Gramann, Klaus; Jung, Tzyy-Ping; Sejnowski, Terrence J; Poizner, Howard


    Cortical brain areas and dynamics evolved to organize motor behavior in our three-dimensional environment also support more general human cognitive processes. Yet traditional brain imaging paradigms typically allow and record only minimal participant behavior, then reduce the recorded data to single map features of averaged responses. To more fully investigate the complex links between distributed brain dynamics and motivated natural behavior, we propose the development of wearable mobile brain/body imaging (MoBI) systems that continuously capture the wearer's high-density electrical brain and muscle signals, three-dimensional body movements, audiovisual scene and point of regard, plus new data-driven analysis methods to model their interrelationships. The new imaging modality should allow new insights into how spatially distributed brain dynamics support natural human cognition and agency.

  16. Goal directed behavior and dyslexia. (United States)

    Chiarenza, Giuseppe Augusto

    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.

  17. Epistemological barriers to radical behaviorism. (United States)

    O'Donohue, W T; Callaghan, G M; Ruckstuhl, L E


    The historian and philosopher of science Gaston Bachelard proposed the concept of epistemological barriers to describe the intellectual challenges encountered by scientists in their work. In order to embrace novel ways of approaching a problem in science, scientists must overcome barriers or obstacles posed by their prior views. For example, Einsteinian physics presents scientists with claims that space is curved and that time and space are on the same continuum. We utilize Bachelard's concept of epistemological barriers to describe the differences between the intellectual journeys students pursuing advanced studies face when attempting to accept cognitive psychology or radical behaviorism. We contend that the folk psychological beliefs that students typically hold when entering these studies pose less challenge to cognitive psychology than to radical behaviorism. We also suggest that these barriers may also partly be involved in the problematic exegesis that has plagued radical behaviorism. In close, we offer some suggestions for dealing with these epistemological barriers.

  19. Mentalization and Dialectical Behavior Therapy. (United States)

    Swenson, Charles R; Choi-Kain, Lois W


    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.

  2. Behavioral interventions for office-based care: behavior change. (United States)

    Delfino, Matthew; Larzelere, Michele McCarthy


    Family physicians play an important role in identifying and treating the behavioral etiologies of morbidity and mortality. Changing behavior is a challenging process that begins with identifying a patient's readiness to change. Interventions, such as motivational interviewing, are used to increase a patient's desire to change, and cognitive behavioral therapy can be initiated to increase a patient's likelihood of change, particularly if barriers are identified. After patients embark on change, family physicians are uniquely positioned to connect them to self-help programs, more intensive psychotherapy, and newer technology-based support programs, and to provide repeated, brief, positive reinforcement. Specific behavioral interventions that can be effective include computerized smoking cessation programs; electronic reminders and support delivered by family physicians or other clinicians for weight loss; linkage to community-based programs for seniors; increased length and demands of in-school programs to support exercise participation by children; and access reduction education to prevent firearm injury.

  7. Using action planning to promote exercise behavior. (United States)

    Conner, Mark; Sandberg, Tracy; Norman, Paul


    Action planning promotes exercise behavior and mediates intention-behavior relationships. The aim of this study is to provide correlational and experimental tests of action planning as mediator of intention-exercise behavior relationships controlling for Theory of Planned Behavior variables and past behavior. In study 1 (N = 777), young adults completed questionnaires assessing Theory of Planned Behavior variables, past behavior, and planning in relation to exercise and 2 weeks later reported exercise behavior. In study 2 (N = 356), young adults were randomly allocated to complete one of two questionnaires and 2 weeks later reported exercise behavior. Both questionnaires contained similar measures to study 1 (Theory of Planned Behavior variables, past behavior in relation to exercise), but one also contained an exercise planning measure. Planning partially mediated intention-behavior relationships and intentions showed a moderated mediation effect: stronger intention-planning-behavior relationships when intentions were strong (study 1). Exercise behavior was higher in planning compared to no planning group, and this difference was greater when intentions were strong (study 2). Action planning mediates intention-exercise behavior relationships, particularly when exercise intentions are strong. Interventions promoting exercise behavior should jointly target intentions and planning.

    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%.

  19. Neuroscience of Compulsive Eating Behavior

    Directory of Open Access Journals (Sweden)

    Catherine F. Moore


    Full Text Available A systematic characterization of compulsivity in pathological forms of eating has been proposed in the context of three functional domains: (1 habitual overeating; (2 overeating to relieve a negative emotional state; and (3 overeating despite aversive consequences. In this review, we provide evidence supporting this hypothesis and we differentiate the nascent field of neurocircuits and neurochemical mediators of compulsive eating through their underlying neuropsychobiological processes. A better understanding of the neurobiological mechanisms that lead to compulsive eating behavior can improve behavioral and pharmacological intervention for disorders of pathological eating.

    The extensive attention devoted to Noam Chomsky's review of Verbal Behavior by B.F. Skinner has resulted in a neglect of more than a dozen other rewiews of the work. These are surveyed and found to be positive and congenial in tone, with many of the reviewers advancing his/her own analysis of speech and language. The dominant criticism of the book was its disregard of central or implicit processes and its lack of experimental data.

    Directory of Open Access Journals (Sweden)

    Deborah M Gordon


    Full Text Available Similar patterns of interaction, such as network motifs and feedback loops, are used in many natural collective processes, probably because they have evolved independently under similar pressures. Here I consider how three environmental constraints may shape the evolution of collective behavior: the patchiness of resources, the operating costs of maintaining the interaction network that produces collective behavior, and the threat of rupture of the network. The ants are a large and successful taxon that have evolved in very diverse environments. Examples from ants provide a starting point for examining more generally the fit between the particular pattern of interaction that regulates activity, and the environment in which it functions.

  15. A theory of behavioral contrast. (United States)

    Killeen, Peter R


    The reinforcers that maintain target instrumental responses also reinforce other responses that compete with them for expression. This competition, and its imbalance at points of transition between different schedules of reinforcement, causes behavioral contrast. The imbalance is caused by differences in the rates at which different responses come under the control of component stimuli. A model for this theory of behavioral contrast is constructed by expanding the coupling coefficient of MPR (Killeen, 1994). The coupling coefficient gives the degree of association of a reinforcer with the target response (as opposed to other competing responses). Competing responses, often identified as interim or adjunctive or superstitious behavior, are intrinsic to reinforcement schedules, especially interval schedules. In addition to that base-rate of competition, additional competing responses may spill over from the prior component, causing initial contrast; and they may be modulated by conditioned reinforcement or punishment from stimuli associated with subsequent component change, causing terminal contrast. A formalization of these hypotheses employed (a) a hysteresis model of off-target responses giving rise to initial contrast, and (b) a competing traces model of the suppression or enhancement of ongoing competitive responses by signals of following-schedule transition. The theory was applied to transient contrast, the following schedule effect, and the component duration effect. © Society for the Experimental Analysis of Behavior.

    Svatošová Veronika


    Full Text Available Buyer behavior of consumers plays one of the key roles in fulfillment of the main goals of a company. It is influenced by many external and internal factors but the company can also influence the final process of buyer decision-making process significantly by its activities. 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 current trends. The article uses the basic terminology of this subject and current bibliography as well as other resources. Theoretical knowledge is based on historic directions of Maslow’s theory of motivation where it is possible to find the basis for a buyer behavior analysis. The article is also based on the formerly carried out questionnaire survey which examines the motives and experience of the respondents with online shopping. By means of the independence test it is verified whether there is a relation between the age of respondents and motivation for online shopping. Subsequently, the survey carried out in person is compared with other relevant research solutions.

    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.

  14. Dopamine Agonists and Pathologic Behaviors

    Directory of Open Access Journals (Sweden)

    Brendan J. Kelley


    Full Text Available The dopamine agonists ropinirole and pramipexole exhibit highly specific affinity for the cerebral dopamine D3 receptor. Use of these medications in Parkinson’s disease has been complicated by the emergence of pathologic behavioral patterns such as hypersexuality, pathologic gambling, excessive hobbying, and other circumscribed obsessive-compulsive disorders of impulse control in people having no history of such disorders. These behavioral changes typically remit following discontinuation of the medication, further demonstrating a causal relationship. Expression of the D3 receptor is particularly rich within the limbic system, where it plays an important role in modulating the physiologic and emotional experience of novelty, reward, and risk assessment. Converging neuroanatomical, physiological, and behavioral science data suggest the high D3 affinity of these medications as the basis for these behavioral changes. These observations suggest the D3 receptor as a therapeutic target for obsessive-compulsive disorder and substance abuse, and improved understanding of D3 receptor function may aid drug design of future atypical antipsychotics.

  17. The acquisition of problem behavior in individuals with developmental disabilities as a behavioral cusp. (United States)

    Robertson, Rachel E


    A behavioral cusp has been defined as a behavior change that produces contact with new contingencies with important and far-reaching consequences. The concept of behavioral cusps has most frequently been used to select target skills taught to learners and to evaluate the importance of those skills; however, the concept is equally applicable to behavior changes that bring about important and far-reaching negative consequences. Although it has been acknowledged that socially undesirable behavior change can also qualify as a behavioral cusp, this area of the cusp concept has been under-examined. In this article, an undesirable behavior change, the acquisition of problem behavior in individuals with developmental disabilities, is compared with criteria for behavioral cusps previously identified in the literature. The advantages of viewing problem behavior as a behavioral cusp are outlined, and implications for practice and research from a behavioral cusp approach to problem behavior are provided. © The Author(s) 2015.

  18. Modifying and developing health behavior. (United States)

    Green, L W


    The literatures on both behavior modification and behavioral development have engendered innovations in public health programs, addressing problems of patient adherance to preventive and therapeutic regimens, delay in seeking diagnosis of illness symptoms, risk-taking behavior, and other aspects of lifestyle associated with health. Because most of this literature derives from psychology, there has been a distinct bias in the construction of interventions, pointing them directly at individuals, usually in a counseling or small group mode of delivery. These developments served public health well enough during a decade or so when the preoccupation was with utilization of health services and medical management of chronic diseases. With the publication of the Lalonde Report in Canada in 1974, the passage of Public Law 94-317 in 1976 in the United States, and similar initiatives in other English-speaking and European countries, the recognition of the greater complexities of lifestyle development and modification in the absence of symptoms has taken hold. Policy makers and public health workers seek a more efficient and equitable set of strategies to meet the behavioral health challenges of modern society without placing the entire weight of responsibility for behavior on the individual or on therapeutic practitioners. Concurrently, on a more global scale and in the developing countries, a concern has emerged for strategies that give individuals, families, and communities a greater role in deciding their own health priorities. The convergence of these two trends--one seeking to distribute responsibility for lifestyle more equitably and the other seeking to distribute responsibility for planning health programs more equitably --calls for policies, strategies, and interventions that will place similar emphasis on health education and organizational, economic, and environmental supports for health behavior. The combination of these elements of support for behavior calls, in

    Cigarette smoking is the leading cause of preventable deaths worldwide and nicotine, the primary psychoactive constituent in tobacco, drives sustained use. The behavioral actions of nicotine are complex and extend well beyond the actions of the drug as a primary reinforcer. Stimuli that are consistently paired with nicotine can, through associative learning, take on reinforcing properties as conditioned stimuli. These conditioned stimuli can then impact the rate and probability of behavior and even function as conditioning reinforcers that maintain behavior in the absence of nicotine. Nicotine can also act as a conditioned stimulus, predicting the delivery of other reinforcers, which may allow nicotine to acquire value as a conditioned reinforcer. These associative effects, establishing non-nicotine stimuli as conditioned stimuli with discriminative stimulus and conditioned reinforcing properties as well as establishing nicotine as a conditioned stimulus, are predicted by basic conditioning principles. However, nicotine can also act non-associatively. Nicotine directly enhances the reinforcing efficacy of other reinforcing stimuli in the environment, an effect that does not require a temporal or predictive relationship between nicotine and either the stimulus or the behavior. Hence, the reinforcing actions of nicotine stem both from the primary reinforcing actions of the drug (and the subsequent associative learning effects) as well as the reinforcement enhancement action of nicotine which is non-associative in nature. Gaining a better understanding of how nicotine impacts behavior will allow for maximally effective tobacco control efforts aimed at reducing the harm associated with tobacco use by reducing and/or treating its addictiveness.

  3. Cognitive Modeling of Social Behaviors (United States)

    Clancey, William J.; Sierhuis, Maarten; Damer. Bruce; Brodsky, Boris


    The driving theme of cognitive modeling for many decades has been that knowledge affects how and which goals are accomplished by an intelligent being (Newell 1991). But when one examines groups of people living and working together, one is forced to recognize that whose knowledge is called into play, at a particular time and location, directly affects what the group accomplishes. Indeed, constraints on participation, including roles, procedures, and norms, affect whether an individual is able to act at all (Lave & Wenger 1991; Jordan 1992; Scribner & Sachs 1991). To understand both individual cognition and collective activity, perhaps the greatest opportunity today is to integrate the cognitive modeling approach (which stresses how beliefs are formed and drive behavior) with social studies (which stress how relationships and informal practices drive behavior). The crucial insight is that norms are conceptualized in the individual &nd as ways of carrying out activities (Clancey 1997a, 2002b). This requires for the psychologist a shift from only modeling goals and tasks - why people do what they do - to modeling behavioral patterns-what people do-as they are engaged in purposeful activities. Instead of a model that exclusively deduces actions from goals, behaviors are also, if not primarily, driven by broader patterns of chronological and located activities (akin to scripts). This analysis is particular inspired by activity theory (Leont ev 1979). While acknowledging that knowledge (relating goals and operations) is fundamental for intelligent behavior, activity theory claims that a broader driver is the person s motives and conceptualization of activities. Such understanding of human interaction is normative (i.e., viewed with respect to social standards), affecting how knowledge is called into play and applied in practice. Put another way, how problems are discovered and framed, what methods are chosen, and indeed who even cares or has the authority to act, are all

  4. Elastic-plastic fracture mechanics analysis of a pressure vessel with an axial outer surface flaw. Pt. 2

    International Nuclear Information System (INIS)

    Brocks, W.; Kuenecke, G.


    Continuing preceding investigations, a further elastic-plastic finite element analysis of a test vessel with a semi-elliptical axial outer surface crack has been performed. The variations of J and CTOD along the crack front and the stress state in the vicinity of the crack are presented. The applicability of analytical approaches to determine J is examined. The FE results are used to analyze the experimental data with respect to the validity of J-controlled crack growth. Local J R -curves of the surface flaw are compared with J R -curves of various specimens of different geometries. Again, it became evident that the local ductile crack growth and, especially, the developing 'canoe shape' of the surface crack cannot be described by a single resistance curve which is assumed to be a material property. A method described in a previous report to predict the ductile crack growth by using local J R -curves which depend on the triaxiality of the stress state did not result in a satisfactory outcome, in the present case. The presumed reasons will be discussed. (orig.) [de

  5. Ductile crack growth resistance of PWR components. Application for structural integrity assessment

    International Nuclear Information System (INIS)

    Bethmont, M.; Eripret, C.; Le Delliou, P.; Frund, J.M.


    Structural integrity assessment of PWR components, as pressure vessel and piping, needs to evaluate the ductile crack growth resistance which is generally characterized by J resistance curves (or J-R curves) based on the path-independent J Integral. These curves are more often obtained from laboratory tests with small specimens as CT-specimens and their application to large component safety analysis could be questionable Indeed, it is well known that J-R curves could depend on the specimen size and on the loading mode (i.e. bending stress versus tensile stress) but this dependency could be different from one material to another. This means that it would depend not only on the stress-strain state but also on the actual local fracture mechanisms (i. e. the damage) occurring before the crack initiation or during the crack propagation. The purpose of this paper is to gather some results of crack growth resistance measurement studied at EDF with different materials in order to show how the effect of the parameters, as specimen geometry and mode of loading, is directly related to the local fracture mechanisms or the microstructure of the materials. For that a number of results are analysed by means of the local approach of fracture which is a very useful tool to predict quantitatively the J-R curve dependency, related to fracture mechanisms (authors). 12 refs., 9 figs

Pharmaceutical companies began hiring psychologists with operant conditioning backgrounds so as to compete successfully in the search ...

  7. Behavioral and Brain Functions. A new journal

    Directory of Open Access Journals (Sweden)

    Sagvolden Terje


    Full Text Available Abstract Behavioral and Brain Functions (BBF is an Open Access, peer-reviewed, online journal considering original research, review, and modeling articles in all aspects of neurobiology or behavior, favoring research that relates to both domains. Behavioral and Brain Functions is published by BioMed Central. The greatest challenge for empirical science is to understand human behavior; how human behavior arises from the myriad functions such as attention, language, memory and emotion; how these functions are reflected in brain structures and functions; and how the brain and behavior are altered in disease. Behavioral and Brain Functions covers the entire area of behavioral and cognitive neuroscience – an area where animal studies traditionally play a prominent role. Behavioral and Brain Functions is published online, allowing unlimited space for figures, extensive datasets to allow readers to study the data for themselves, and moving pictures, which are important qualities assisting communication in modern science.

  9. Emotional responses to behavioral economic incentives for health behavior change. (United States)

    van der Swaluw, Koen; Lambooij, Mattijs S; Mathijssen, Jolanda J P; Zeelenberg, Marcel; Polder, Johan J; Prast, Henriëtte M


    Many people aim to change their lifestyle, but have trouble acting on their intentions. Behavioral economic incentives and related emotions can support commitment to personal health goals, but the related emotions remain unexplored. In a regret lottery, winners who do not attain their health goals do not get their prize but receive feedback on what their forgone earnings would have been. This counterfactual feedback should provoke anticipated regret and increase commitment to health goals. We explored which emotions were actually expected upon missing out on a prize due to unsuccessful weight loss and which incentive-characteristics influence their likelihood and intensity. Participants reported their expected emotional response after missing out on a prize in one of 12 randomly presented incentive-scenarios, which varied in incentive type, incentive size and deadline distance. Participants primarily reported feeling disappointment, followed by regret. Regret was expected most when losing a lottery prize (vs. a fixed incentive) and intensified with prize size. Multiple features of the participant and the lottery incentive increase the occurrence and intensity of regret. As such, our findings can be helpful in designing behavioral economic incentives that leverage emotions to support health behavior change.

    Greenwald, Mark K.


    Summary The field of behavioral economics suggests that food and activity choices are governed by costs, available alternatives, and reinforcement. Here, we review basic and translational research using a behavioral economic (BE) framework with overweight or obese children up to age 18. We address BE concepts and methods, discuss developmental issues, the continuum of BE intervention approaches, findings of studies focused on increasing the cost of unwanted behaviors (i.e., energy-dense food intake and sedentary behavior) and decreasing the cost of desired behaviors (i.e., healthy food intake and PA), and our team's recent basic behavioral studies using BE approaches with minority adolescents.

  12. Environmental contaminants as origins of disordered behavior

    Energy Technology Data Exchange (ETDEWEB)

    Weiss, B.


    Behavioral toxicology studies the behavioral effects of contaminants, such as heavy metals, in environmental and occupational settings. A classic example of metal poisoning with behavioral effects is Pink Disease, or acrodynia, due to mercurous chloride intoxication in children. Thalidomide is a more prominent example. Behavioral changes, unlike tangible consequences of pollution, are difficult to perceive as dangers and to correct. Other examples of environmental pollutants causing behavioral symptoms upon intoxication are polybrominated biphenyls, lead, mercury, methylmercury, and a variety of food additives. Sensitivity to food colors and flavors is suspected to be the cause of behavioral abnormalities in children now labeled as hyperactive or hyperkinetic. (ERB)

    Y. Azzouz


    Full Text Available An analog behavioral model of high power gate turn-off thyristor (GTO is developed in this paper. The fundamental methodology for the modeling of this power electronic circuit is based on the use of the realistic diode consideration of non-linear junctions. This modeling technique enables to perform different simulations taking into account the turn-on and turn-off transient behaviors in real-time. The equivalent circuits were simulated with analog software developed in our laboratory. It was shown that the tested simple and compact model allows the generation of accurate physical characteristics of power thyristors under dynamic conditions. The model understudy was validated with analog simulations based on operational amplifier devices.


    Hitchcock, David I.


    1. It has been shown by titration experiments that the globulin edestin behaves like an amphoteric electrolyte, reacting stoichiometrically with acids and bases. 2. The potential difference developed between a solution of edestin chloride or acetate separated by a collodion membrane from an acid solution free from protein was found to be influenced by salt concentration and hydrogen ion concentration in the way predicted by Donnan's theory of membrane equilibrium. 3. The osmotic pressure of such edestin-acid salt solutions was found to be influenced by salt concentration and by hydrogen ion concentration in the same way as is the potential difference. 4. The colloidal behavior of edestin is thus completely analogous to that observed by Loeb with gelatin, casein, and egg albumin, and may be explained by Loeb's theory of colloidal behavior, which is based on the idea that proteins react stoichiometrically as amphoteric electrolytes and on Donnan's theory of membrane equilibrium.

  15. Fathers and preschool behavior problems. (United States)

    DeKlyen, M; Biernbaum, M A; Speltz, M L; Greenberg, M T


    Fathers have seldom been the focus of research investigating the causes and correlates of early behavior problems. Two studies examined fathers of preschool boys with and without clinic-referred behavior problems. Six domains of risk were examined: life stress, social support, psychological symptoms, parenting attitudes, positive involvement, and harsh discipline. Clinic fathers differed from fathers of matched comparison boys with respect to all of these except social support, but only harsh discipline contributed uniquely to clinic status. These domains correctly classified 81% of the boys. Within the clinic group, teacher-rated problem severity 1 year later was predicted by fathers' life stress, psychological symptoms, and positive involvement, indicating that different factors may account for initial clinic status versus stability of problems. Mothers' self-report data better predicted clinic group membership, whereas fathers' data better predicted Year 2 outcomes for clinic boys.

  16. Climatic effects on planning behavior. (United States)

    Liu, Yong; Kostakos, Vassilis; Li, Hongxiu


    What mechanism links climate change and social change? Palaeoanthropological analysis of human remains suggests that abrupt climate change is linked to societal restructuring, but it has been challenging to reliably identify the exact mechanisms underlying this relationship. Here we identify one potential mechanism that can link climate to behavior change, and underpins many of the reported findings on social restructuring. Specifically, we show that daily weather is linked to human planning behavior, and this effect is moderated by climate. Our results demonstrate that as weather gets colder, humans increase their planning in cold regions and decrease planning in warm regions. Since planning has previously been linked to group efficiency, cooperation, and societal organization, our work suggests planning is one mechanism that can link climate change to societal restructuring.

    The dominant computational approach to model operant learning and its underlying neural activity is model-free reinforcement learning (RL). However, there is accumulating behavioral and neuronal-related evidence that human (and animal) operant learning is far more multifaceted. Theoretical advances in RL, such as hierarchical and model-based RL extend the explanatory power of RL to account for some of these findings. Nevertheless, some other aspects of human behavior remain inexplicable even in the simplest tasks. Here we review developments and remaining challenges in relating RL models to human operant learning. In particular, we emphasize that learning a model of the world is an essential step before or in parallel to learning the policy in RL and discuss alternative models that directly learn a policy without an explicit world model in terms of state-action pairs.

  20. Animal studies of addictive behavior. (United States)

    Vanderschuren, Louk J M J; Ahmed, Serge H


    It is increasingly recognized that studying drug taking in laboratory animals does not equate to studying genuine addiction, characterized by loss of control over drug use. This has inspired recent work aimed at capturing genuine addiction-like behavior in animals. In this work, we summarize empirical evidence for the occurrence of several DSM-IV-like symptoms of addiction in animals after extended drug use. These symptoms include escalation of drug use, neurocognitive deficits, resistance to extinction, increased motivation for drugs, preference for drugs over nondrug rewards, and resistance to punishment. The fact that addiction-like behavior can occur and be studied in animals gives us the exciting opportunity to investigate the neural and genetic background of drug addiction, which we hope will ultimately lead to the development of more effective treatments for this devastating disorder.

  1. [Addictive behavior among the elderly]. (United States)

    Menecier, Pascal; Fernandez, Lydia


    Addictive behavior still persists among the elderly, mainly concerning substance abuse, such as alcohol, tobacco or psychotropic drugs and addictive practices such as gambling. Illegal substances or cyber-addictions appear much less often. The environment (place of residence or care) and/or economic factors may influence behavior and practices. The incidence of somatic illness or psychiatric disorders, such as cognitive impairment among the elderly patients, complicates even further the presentation of addictive disorders and their treatment. The age factor does not seem to lessen the suffering felt by the patient and care is required in an equal manner for all ages. Prevention (maintenance of personal autonomy and quality of life throughout the ageing process) plays an essential role along with the offer of care. The lack of scientific data such as the absence of validation for adult care among the elderly, leave wide scope for epidemiological, clinical and theoretical research.

  4. Transcending behaviorism in communication education. (United States)

    Hartrick, G


    During the past decade, nursing education has been engaged in a curriculum revolution. Although this ongoing revolution has led to profound changes in nursing curricula, one area that requires further scrutiny is communication education. This article addresses the limitations of behavioral communication curricula and suggests a pedagogical process responsive to the complexity of human caring relationships and the intricacies of relational practice. The discussion includes a description of a nursing communication course developed according to the principles of transformational learning theory.

    Wells, V.K.; Chang, S.W.; Oliveira-Castro, J.M.; Pallister, J.


    A segmentation approach is presented using both traditional demographic segmentation bases (age, social class/occupation, and working status) and a segmentation by benefits sought. The benefits sought in this case are utilitarian and informational reinforcement, variables developed from the Behavioral Perspective Model (BPM). Using data from 1,847 consumers and from a total of 76,682 individual purchases, brand choice and price and reinforcement responsiveness were assessed for each segment a...

  10. Critical behavior from Schrodinger representation

    International Nuclear Information System (INIS)

    Suranyi, P.


    In this paper, the Schrodinger equation for φ 4 field theory is reduced to an infinite set of integral equations. A systematic truncation scheme is proposed and it is solved in second order to obtain the approximate critical behavior of the renormalized mass. The correlation exponent is given as a solution of a transcendental equation. It is in good agreement with the Ising model in all physical dimensions

  11. Climatic Effects on Planning Behavior


    Liu, Yong; Kostakos, Vassilis; Li, Hongxiu


    What mechanism links climate change and social change? Palaeoanthropological analysis of human remains suggests that abrupt climate change is linked to societal restructuring, but it has been challenging to reliably identify the exact mechanisms underlying this relationship. Here we identify one potential mechanism that can link climate to behavior change, and underpins many of the reported findings on social restructuring. Specifically, we show that daily weather is linked to human planning ...

  12. Drug use as consumer behavior. (United States)

    Foxall, Gordon Robert; Sigurdsson, Valdimar


    Seeking integration of drug consumption research by a theory of memory function and emphasizing drug consumption rather than addiction, Müller & Schumann (M&S) treat drug self-administration as part of a general pattern of consumption. This insight is located within a more comprehensive framework for understanding drug use as consumer behavior that explicates the reinforcement contingencies associated with modes of drug consumption.

    浜田, 文雅


    This paper attempts to propose an alternative microeconomic theory of consumer behavior in terms of distributional approach. A model determining the optimal priority order of and demand for consumer goods not only of the homogeneous type but also of the heterogeneous type under the budget constraint of a consumer and the market conditions is presented. Utility of a commodity is decomposed into the value in use and the value in quality. The latter is assumed to depend on personal income level....

  14. Social Capital and Smoking Behavior


    Lorenzo Rocco; Beatrice d'Hombres


    In this paper, we explore one mechanism that may underlie the negative relationship between social capital and smoking: whether social capital strengthens the effect of anti-smoking regulations. We use data on smoking behaviors collected immediately before and after the implementation of smoking bans in public places in Germany in order to determine whether the impact of these bans on smoking prevalence and intensity is greater among individuals richer in social capital. We find that smoking ...

  17. Manneristic behaviors of visually impaired children. (United States)

    Molloy, Alysha; Rowe, Fiona J


    To review the literature on visual impairment in children in order to determine which manneristic behaviors are associated with visual impairment, and to establish why these behaviors occur and whether severity of visual impairment influences these behaviors. A literature search utilizing PubMed, OVID, Google Scholar, and Web of Knowledge databases was performed. The University of Liverpool ( ) and local library facilities were also searched. The main manneristic or stereotypic behaviors associated with visual impairment are eye-manipulatory behaviors, such as eye poking and rocking. The degree of visual impairment influences the type of behavior exhibited by visually impaired children. Totally blind children are more likely to adopt body and head movements whereas sight-impaired children tend to adopt eye-manipulatory behaviors and rocking. The mannerisms exhibited most frequently are those that provide a specific stimulation to the child. Theories to explain these behaviors include behavioral, developmental, functional, and neurobiological approaches. Although the precise etiology of these behaviors is unknown, it is recognized that each of the theories is useful in providing some explanation of why certain behaviors may occur. The age at which the frequency of these behaviors decreases is associated with the child's increasing development, thus those visually impaired children with additional disabilities, whose development is impaired, are at an increased risk of developing and maintaining these behaviors. Certain manneristic behaviors of the visually impaired child may also help indicate the cause of visual impairment. There is a wide range of manneristic behaviors exhibited by visually impaired children. Some of these behaviors appear to be particularly associated with certain causes of visual impairment or severity of visual impairment, thus they may supply the practitioner with useful information.

  18. The behavior analytic perspective: its nature, prospects, and limitations for behavior therapy. (United States)

    Hawkins, R P; Forsyth, J P


    Behavior analysis is defined as a natural science approach to behavior--with both basic and applied branches--and contrasted with cognitive psychology. Behavior analysis is described as an integrated science that views a person's interactions with the environment as selecting certain behaviors--or rather, environment-behavior relations--making them more probable, given certain subsequent stimulus situations. It seeks an understanding that promotes effective action, which fits the clinical interests of behavior therapy. It promotes persistent searching for environmental causes, which has resulted in a remarkable range of successes, clinical and other. We explore the reasons that all behavior therapists are not behavior analysts and suggest needed future developments.

  19. Structural behavior of cable superconductors

    International Nuclear Information System (INIS)

    Becker, H.; Marston, P.


    The structural properties of cable superconductor coils, for particle accelerators such as the Tevatron and the CBA (Colliding Beam Accelerator), depend upon direction of loading. For compression perpendicular to the ''flat faces'' of the conductor, the coils exhibit nonlinear, inelastic and time dependent behavior. The same is true for ''inplane'' compression loading perpendicular to the conductor edges. In the lengthwise direction, the coils display tension and compression stress-strain curves typical of structural metals. The loading of primary concern is compression perpendicular to the conductor faces since deformations in that direction can have a major influence on magnetic field quality. However, the coil behavior under that condition is uncertain because of the nonlinear stress strain curve complicated by creep and relaxation at the stress levels induced by preloading and Lorentz forces. Furthermore, the stiffness of the loading fixture appears to influence the data as shown by results from tests run under different conditions at Berkeley, Brookhaven and MIT. The paper displays test data on stress-strain curves for all three loading directions. Results are presented for RT, 77 K and 4 K behavior. Data of various investigators are compared. The applicability of a relatively simple power law between stress and strain is depicted

  20. Multifractal formalisms of human behavior. (United States)

    Ihlen, Espen A F; Vereijken, Beatrix


    With the mounting realization that variability is an inevitable part of human behavior comes the need to integrate this phenomenon in concomitant models and theories of motor control. Among other things, this has resulted in a debate throughout the last decades about the origin of variability in behavior, the outcome of which has important implications for motor control theories. To date, a monofractal formalism of variability has been used as the basis for arguing for component- versus interaction-oriented theories of motor control. However, monofractal formalism alone cannot decide between the opposing sides of the debate. The present theoretical overview introduces multifractal formalisms as a necessary extension of the conventional monofractal formalism. In multifractal formalisms, the scale invariance of behavior is numerically defined as a spectrum of scaling exponents, rather than a single average exponent as in the monofractal formalism. Several methods to estimate the multifractal spectrum of scaling exponents - all within two multifractal formalisms called large deviation and Legendre formalism - are introduced and briefly discussed. Furthermore, the multifractal analyses within these two formalisms are applied to several performance tasks to illustrate how explanations of motor control vary with the methods used. The main section of the theoretical overview discusses the implications of multifractal extensions of the component- and interaction-oriented models for existing theories of motor control.

  1. Behavioral economics and regulatory analysis. (United States)

    Robinson, Lisa A; Hammitt, James K


    Behavioral economics has captured the interest of scholars and the general public by demonstrating ways in which individuals make decisions that appear irrational. While increasing attention is being focused on the implications of this research for the design of risk-reducing policies, less attention has been paid to how it affects the economic valuation of policy consequences. This article considers the latter issue, reviewing the behavioral economics literature and discussing its implications for the conduct of benefit-cost analysis, particularly in the context of environmental, health, and safety regulations. We explore three concerns: using estimates of willingness to pay or willingness to accept compensation for valuation, considering the psychological aspects of risk when valuing mortality-risk reductions, and discounting future consequences. In each case, we take the perspective that analysts should avoid making judgments about whether values are "rational" or "irrational." Instead, they should make every effort to rely on well-designed studies, using ranges, sensitivity analysis, or probabilistic modeling to reflect uncertainty. More generally, behavioral research has led some to argue for a more paternalistic approach to policy analysis. We argue instead for continued focus on describing the preferences of those affected, while working to ensure that these preferences are based on knowledge and careful reflection. © 2011 Society for Risk Analysis.

  2. Fathers' behaviors and children's psychopathology. (United States)

    Flouri, Eirini


    The psychological literature on how fathers' behaviors may be related to children's psychopathology has grown substantially in the last three decades. This growth is the result of research asking the following three overarching questions: (1) what is the association between family structure, and particularly biological fathers' non-residence, and children's psychopathology, (2) what is the association between fathers' parenting and children's psychopathology, and (3) what is the association between fathers' psychopathology and children's psychopathology. The three broad theoretical perspectives relevant to this literature are the standard family environment model, the passive genetic model, and the child effects model. The evidence from studies comparing the first two models seems to suggest that the origin of the association between parental divorce and children's emotional and behavioral problems is largely shared environmental in origin, as is the association between resident fathers' parenting and children's emotional and behavioral problems, according to studies comparing the standard family environment model with the child effects model. However, research needs to compare appropriately all theoretical perspectives. The paper discusses this, and also points to the importance of considering theory-driven specificity in modeling effects. Copyright 2010 Elsevier Ltd. All rights reserved.

  3. [Health behavior change: motivational interviewing]. (United States)

    Pócs, Dávid; Hamvai, Csaba; Kelemen, Oguz


    Public health data show that early mortality in Hungary could be prevented by smoking cessation, reduced alcohol consumption, regular exercise, healthy diet and increased adherence. Doctor-patient encounters often highlight these aspects of health behavior. There is evidence that health behavior change is driven by internal motivation rather than external influence. This finding has led to the concept of motivational interview, which is a person-centered, goal-oriented approach to counselling. The doctor asks targeted questions to elicit the patient's motivations, strengths, internal resources, and to focus the interview around these. The quality and quantity of the patient's change talk is related to better outcomes. In addition, the interview allows the patient to express ambivalent feelings and doubts about the change. The doctor should use various communication strategies to resolve this ambivalence. Furthermore, establishing a good doctor-patient relationship is the cornerstone of the motivational interview. An optimal relationship can evoke change talk and reduce the patient's resistance, which can also result in a better outcome. The goal of the motivational interview is to focus on the 'why' to change health behavior rather than the 'how', and to utilize internal motivation instead of persuasion. This is the reason why motivational interview has become a widely-accepted evidence based approach. Orv Hetil. 2017; 158(34): 1331-1337.

Center for Complex Systems and Brain Sciences


    Humans engage in a seemingly endless variety of different behaviors, of which some are found across species, while others are conceived of as typically human. Most generally, behavior comes about through the interplay of various constraints - informational, mechanical, neural, metabolic, and so on - operating at multiple scales in space and time. Over the years, consensus has grown in the research community that, rather than investigating behavior only from bottom up, it may be also well understood in terms of concepts and laws on the phenomenological level. Such top down approach is rooted in theories of synergetics and self-organization using tools from nonlinear dynamics. The present compendium brings together scientists from all over the world that have contributed to the development of their respective fields departing from this background. It provides an introduction to deterministic as well as stochastic dynamical systems and contains applications to motor control and coordination, visual perception and illusion, as well as auditory perception in the context of speech and music.

  5. Interventions to Increase Walking Behavior (United States)

    Williams, David M.; Matthews, Charles; Rutt, Candace; Napolitano, Melissa A.; Marcus, Bess H.


    Walking is the most prevalent and preferred method of physical activity for both work and leisure purposes, thus making it a prime target for physical activity promotion interventions. We identified 14 randomized controlled trials, which tested interventions specifically targeting and assessing walking behavior. Results show that among self-selected samples intensive interventions can increase walking behavior relative to controls. Brief telephone prompts appear to be as effective as more substantial telephone counseling. Although more research is needed, individual studies support prescriptions to walk 5–7 d/wk versus 3–5 d/wk and at a moderate (versus vigorous) intensity pace, with no differences in total walking minutes when single or multiple daily walking bouts are prescribed. Mediated interventions delivering physical activity promotion materials through non-face-to-face channels may be ideal for delivering walking promotion interventions and have shown efficacy in promoting overall physical activity, especially when theory-based and individually tailored. Mass media campaigns targeting broader audiences, including those who may not intend to increase their physical activity, have been successful at increasing knowledge and awareness about physical activity, but are often too diffuse to successfully impact individual behavior change. Incorporating individually tailored programs into broader mass media campaigns may be an important next step, and the Internet could be a useful vehicle. PMID:18562974

  13. Connections with nature and environmental behaviors. (United States)

    Geng, Liuna; Xu, Jingke; Ye, Lijuan; Zhou, Wenjun; Zhou, Kexin


    The influence of environmental attitudes on environmental behaviors has long been discussed. However, few studies have addressed the foundation of such attitudes. In the present study, we explored primitive belief underlying environmental attitudes, i.e., connections with nature, and its relationship with pro-environmental behaviors. Specifically, we used scales, a computerized Implicit Association Test, and a situational simulation experiment to examine both explicit and implicit connections with nature, both deliberate and spontaneous environmental behaviors, and to find correlations between environmental connectedness and environmental behaviors. Results showed that explicit connectedness was positively correlated with deliberate environmental behaviors, while implicit connectedness was positively correlated with spontaneous environmental behaviors. Additionally, explicit and implicit connectedness was independent of each other. In conclusion, the current study confirms the positive role played by connections with nature in promoting environmental behavior, and accordingly suggests means to encourage pro-environmental behavior by enhancing people's connectedness to nature.

    The present paper analyzes consistencies between the philosophical systems of David Hume and B. F. Skinner, focusing on their conceptualization of causality and attitudes about scientific behavior. The ideas that Hume initially advanced were further developed in Skinner's writings and shaped the behavior-analytic approach to scientific behavior. Tracing Skinner's logical antecedents allows for additional historical and philosophical clarity when examining the development of radical behaviorism.

    Bueno, Roberto; Universidad de San Martín de Porres / Universidad Nacional Federico Villarreal


    As supposed events being accessible to a unique observer, private events posit an interesting challenge to a behavioristic psychology. Three historical variants of behaviorism dealt with the problem of private events: methodological behaviorism, radical behaviorism and interbehaviorism. The basic argument of the two last views, and that distinguishes them from the former, is that private events are comprised into the scope of an objective science of behavior. The analysis of these accounts pe...

    Behavior of cattle is a simple and easily established indicator of their health condition, production characteristics and welfare, showing whether and how the animal has adapted to the maintenance conditions. Essentially, all forms of cattle behavior are accompanied by certain physiological changes in the organism, and the basic moving forces of behavior are congenital. The moving forces of behavior of cattle are narrowed down to a certain number of biological needs (the need for food, water,...

  3. Skinner's verbal behavior, Chomsky's review, and mentalism. (United States)

    Stemmer, N


    Skinner's Verbal Behavior (1957) is a comprehensive treatise that deals with most aspects of verbal behavior. However, its treatment of the learning of grammatical behavior has been challenged repeatedly (e.g., Chomsky, 1959). The present paper will attempt to show that the learning of grammar and syntax can be dealt with adequately within a behavior-analytic framework. There is no need to adopt mentalist (or cognitivist) positions or to add mentalist elements to behaviorist theories. PMID:2103585

Many clinically used antipsychotic drugs, including the typical drug haloperidol and atypical drugs clozapine, risperidone, olanzapine, quetiapine, aripiprazole and amisulpride, all disrupt active maternal responses (e.g. pup retrieval, pup licking and nest building) to various extents. In this review, I present a summary of recent studies on the behavioral effects and neurobiological mechanisms of antipsychotic action on maternal behavior i...

  5. Relationship between information-seeking behavior and innovative behavior in Chinese nursing students. (United States)

    Zhong, Zhuqing; Hu, Dehua; Zheng, Feng; Ding, Siqing; Luo, Aijing


    In the information-based economy, information literacy has become the foundation of scientific literacy, and provides the basis for innovative growth. Exploring the relationship between information-seeking behaviors and innovative behaviors of nursing students could help guide the development of information literacy education and training for nursing students. The relationship between information-seeking behavior and innovative behavior in nursing students has received little attention, however. This study aims to explore the relationship between information-seeking behavior and innovative behavior of nursing students. Nursing students in Xiangya Medical School, Central South University and Medical School of Hunan Normal University in the Chinese Province of Hunan were surveyed with an information-seeking behavior scale and an innovative behavior scale. A total of 1247 nursing students were included in the final analysis. The results showed that both information-seeking behavior and innovative behavior were significantly better in undergraduates than in junior college nursing students (P information-seeking behavior was positively related to innovative behavior (r = 0.63, P information-seeking behavior were also correlated with innovative behavior in varying degrees. Furthermore, information utilization was proved to be the strongest predictor of innovative behavior. Information-seeking behavior is positively associated with innovative behavior among nursing students. There is a need to integrate information literacy education with information retrieval courses, especially in the aspects of information utilization, retrieval, and assessment.

  15. Sexual behaviors in children: evaluation and management. (United States)

    Kellogg, Nancy D


    Sexual behaviors in children are common, occurring in 42 to 73 percent of children by the time they reach 13 years of age. Developmentally appropriate behavior that is common and frequently observed in children includes trying to view another person's genitals or breasts, standing too close to other persons, and touching their own genitals. Sexual behaviors become less common, less frequent, or more covert after five years of age. Sexual behavior problems are defined as developmentally inappropriate or intrusive sexual acts that typically involve coercion or distress. Such behaviors should be evaluated within the context of other emotional and behavior disorders, socialization difficulties, and family dysfunction, including violence, abuse, and neglect. Although many children with sexual behavior problems have a history of sexual abuse, most children who have been sexually abused do not develop sexual behavior problems. Children who have been sexually abused at a younger age, who have been abused by a family member, or whose abuse involved penetration are at greater risk of developing sexual behavior problems. Although age-appropriate behaviors are managed primarily through reassurance and education of the parent about appropriate behavior redirection, sexual behavior problems often require further assessment and may necessitate a referral to child protective services for suspected abuse or neglect.
