BackgroundHabituation, a form of non-associative learning, has several well-defined characteristics that apply to a wide range of physiological and behavioral responses in many organisms. In classic patch time allocation models, habituation is considered to be a major mechanistic component of parasitoid behavioral strategies. However, parasitoid behavioral responses to host cues have not previously been tested for the known, specific characteristics of habituation.MethodsIn the laboratory, we tested whether the foraging behavior of the egg parasitoidTrissolcus basalisshows specific characteristics of habituation in response to consecutive encounters with patches of host (Nezara viridula) chemical contact cues (footprints), in particular: (i) a training interval-dependent decline in response intensity, and (ii) a training interval-dependent recovery of the response.ResultsAs would be expected of a habituated response, wasps trained at higher frequencies decreased their behavioral response to host footprints more quickly and to a greater degree than those trained at low frequencies, and subsequently showed a more rapid, although partial, recovery of their behavioral response to host footprints. This putative habituation learning could not be blocked by cold anesthesia, ingestion of an ATPase inhibitor, or ingestion of a protein synthesis inhibitor.DiscussionOur study provides support for the assumption that diminishing responses of parasitoids to chemical indicators of host presence constitutes habituation as opposed to sensory fatigue, and provides a preliminary basis for exploring the underlying mechanisms.

Behavioral observation audiometry (BOA) is the only test protocol that provides a direct measure of hearing. This valuable technique can be used to monitor hearing and hearing aid benefit in infants who are not yet able to participate in visual reinforcement audiometry (VRA). In this article, I present a carefully developed protocol that uses changes in sucking, resulting in a reliable threshold measures. Key points include Auditory brainstem response (ABR) testing, auditory steady state response (ASSR) testing, and otoacoustic emissions (OAEs) testing provide critical information about the status of the auditory pathways but are not direct measures of hearing. Only behavioral testing provides a direct measure of hearing. Behavioral testing can be used to monitor hearing and performance with hearing technology. When carefully performed, using appropriate criteria including using changes in sucking as an indication of a response, behavioral observation audiometry can be used by clinicians to accurately measure thresholds in infants cognitively less than 6 months of age.

The Disraeli facility, which was completed in 1960, consists of several overpasses utilizing rolled steel beam construction and a riveted steel plate girder bridge crossing the Red River in Winnipeg, Manitoba. The total length of the facility is approximately 707 m (2320 ft). In 1984, the City of Winnipeg commissioned Reid Crowther and Partners Limited to perform a load test on the facility to ascertain the possibility of increasing the maximum gross vehicle weight limit. The tests were performed on three consecutive Sundays, from September 23 to October 7, 1984.Three spans were tested. One normal and one skewed span were selected for the overpasses to study possible differences in their behavior along the exterior span of a three-span continuous riveted plate girder bridge over the Red River. The test was designed to determine the structural response of the bridges at different load levels, to determine the load distribution characteristics, and to investigate dynamic impact values for the test vehicles.This paper describes the instrumentation layout, data acquisition system, test vehicles, and testing procedures. Test results and comparisons with the predicted values utilizing conventional analysis are included.

Annotation:

Article presents the results of testing managers’ behavior and response towards business environment. The study develops ideas how to extend current management theory with behavioral approach. Research method is based on in-depth empirical qualitative analysis, results are subject of quantitative verification using statistical methods which allows reaching better results. Research proceeds inductively, it means that new knowledge is generated as outcome and matched to theories. Decisions are examined as responses towards business environment components, correlations and significances between active or passive managers’ behavior are demonstrated. Proactive managerial approach is characterized by frequent change and diversification in suppliers, customers, human resources and product portfolio. As a conclusion, managerial response can be interpreted as a product of managers’ activity, personal preferences and abilities. The re-orientation towards recognition of active or passive behavior is developed and matched towards current theories. It can be assumed, that the current scientific discussion is potentially relevant in seeking to explain the role of individual manager. In summary, the analysis and the outcomes have proved managers’ exceptional flexibility in counteracting actively the shortcomings of external context.

The amphibian Xenopus laevis embryo (tadpole) provides a satisfactory alternative to mammalian screening for structural teratogens. Testing was undertaken to extend the usefulness of this species for behavioral teratogenicity testing. One simple and eight operant conditioning paradigms were examined: none elicited learning in Xenopus embryos. Adaptation to the conditioning stimulus (light) and freezing in response to the unconditioned stimulus (shock) were responses incompatible with conditioned learning.

In the course of routinely performed subchronic toxicity studies with laboratory rodents, functional neurotoxicity, i.e., behavioral changes, usually are noted first during the daily cageside observations of all animals, Observation and neurologic examination of a few key animals provide a tentative diagnosis. Subsequent automated testing procedures for further characterization and quantifying behavioral changes might include motor activity, startle response, hurdle stepping, and maze behavior. Automated testing serves to assess the no observable effect under conditions of blind testing and provides further refinement of the diagnosis. Behavioral changes should be assessed as early as possible after onset of testing, i.e., during acute tests for mortality and the subsequent subchronic range-finding studies. Subsequent subchronic organ toxicity studies are then carried out by following a validated experimental protocol, including automated testing procedures and appropriate neuropathologic evaluation.

Field assessments of the health and welfare of kenneled dogs (Canis lupus familiaris) must be both accurate and rapid. In order to facilitate such evaluations, especially by individuals with limited training in canine behavior and welfare, a non-invasive tool was developed and pilot-tested utilizing dogs housed in commercial breeding facilities. Behavioral responses to approach were organized into three categories: red, indicating a fearful response to approach, green, indicating an affiliative or neutral response to approach, and yellow, indicating an ambivalent response to approach. The inter-rater reliability (IRR) of the tool when used by both behavioral experts and novice raters was evaluated with and without the presence of the dog’s familiar caretaker. Utilizing Cohen’s kappa, the experts had almost perfect levels of agreement (kappa=0.87). The novice raters had substantial levels of agreement (kappa=0.74). Overall, the dogs assessed by the novice raters had high proportions of green responses to approach and there was no statistically significant effect of caretaker presence on the proportion of green responses to approach. The assessment tool evaluated herein appears to have a high degree of IRR whether used by experts in canine behavior or by novice raters and may be a useful screening tool to determine the need for more in-depth welfare assessments.

Der volle Inhalt der Quelle

Annotation:

A set of stimuli comprises an equivalence class if the three relations of reflexivity, symmetry, and transitivity are present (Sidman & Tailby, 1982). Although behaviorological researchers have suggested that the training and testing sequence may affect equivalence class formation, this has not been studied directly. The purpose of this study was to investigate the efficacy of two different arrangements of training and testing on the formation of classes of equivalent stimuli. Five middle school students were taught eight conditional discriminations with four classes of stimuli, three stimuli per class (A1B1C1, A2B2C2, A3B3C3, and A4B4C4). A fifth class of stimuli, A5B5C5, was used as control stimuli. Experimental stimuli consisted of five chemical elements, with three attributes per element (name, symbol, and atomic number). The formation of three-member equivalence classes was evaluated by testing students for symmetrical and transitive conditional discriminations involved in the training relations. Two phase arrangements were used with each student. Phase Arrangement I (incorporating n-stage testing) was as follows: (a) AM; (b) B1C1; (c) A1B1 and B1C1 mixed together; (d) test (A1C1, C1A1, A5C5, and C5A5); (e) AM; (f) B2C2; (g) A2B2 and B2C2 mixed together; (h) test (A2C2, C2A2, A5C5, and C5A5); (i) AM, B1C1, AM, and B2C2 all mixed together; and (j) test (AlCl, C1A1, A2C2, C2A2, A5C5, and C5A5). Phase Arrangement II was similar, except that test phases (d) and (h) were eliminated. Stimulus classes A3B3C3 and A4B4C4 were arranged analogously to provide a counterbalanced design. One student performed equally well on equivalence tests with both phase arrangements. Two students performed slightly better on equivalence tests with intermediate testing. One student's performance on equivalence tests demonstrated no equivalence class formation with n-stage testing and much more accurate, although varied, responding with intermediate testing. A 5th student who did not meet the pretest requirements for the study was nevertheless allowed to complete the experimental tasks because his test results were unusual. His first test score was far below chance level, but scores improved with subsequent testing. The results suggest that an intermediate testing arrangement may decrease intersubject variability and, for some individuals, may improve equivalence test performance.

Annotation:

This study investigates the constructs of Derivation and Complexity and how they relate to latency. Derivation and Complexity are theoretical constructs that have been posited as two of the main factors in differences in latency to responding in implicit measures such as the Implicit Relational Assessment Procedure (IRAP) and the Implicit Association Task (IAT). This study trained participants to relate two groups of novel stimuli in a linear fashion and then tested their latency to responding to derived relations (relations based on previously trained relations, but not directly trained themselves). The study then analyzed participant's latency to responding after dividing the responses based on derivation, complexity, and phase. The study found a significant relationship between phase and latency (p=.01), derivation and latency (p=.01), and complexity and latency (p=.04). This indicates that brief, immediate relational responses are influenced by both derivation and complexity as well as practice responding and these variables should be considered in future investigations into implicit attitudes.

Annotation:

The design of interface elements in geotechnical engineering traditionally involves empiricism and lacks a solid fundamental underpinning based on the controlling mechanisms. These design shortcomings exist due to deficiencies in the fundamental understanding of geotechnical interface behaviors and the lack of test methods and devices available to directly measure interface properties in situ. The current work strives to improve the state of geotechnical knowledge and design with regard to interface behavior through fundamental laboratory studies and the development and use of a new in situ testing device. The current investigations are focused across a range of scales from micromechanical interactions to full scale field implementation. A series of laboratory investigations at the micromechanical level have been performed, specifically aimed at investigating the mechanisms controlling granular interactions against conventional and textured friction sleeves, and hook and loop type interactions present within textured geomembrane - geotextile systems. Additionally, a new in situ testing device has been designed and developed, the Multi Piezo Friction Attachment (MPFA), to allow for the characterization of geotechnical interface properties in situ within the context of an effective stress framework. The MPFA simultaneously provides four independent measures of interface friction (f

Repair of DNA damage is one of the most important processes undergone in a dividing cell. This is a two-part study undertaken to better understand some of the proteins involved in the sensing and repair of DNA damage in Drosophila melanogaster. The first portion of this experiment followed two Drosophila Rad51 paralogs, dmRad51D and dmXRRC2, and using constructs tagged with GFP, found that they entered the nucleus in response to drug induced DNA damage. Approximately one hour after the induction of DNA damage via bleomycin, dmRad51D and dmXRCC2 entered the nucleus of the Drosophila culture cells, where they remained for the next three to four hours. Following this period in the nucleus, the cells were visualized moving back into the cytosol. The second portion of this experiment was concerned with the four Drosophila Rad51 paralogs (dmRad51 D, dmXRCC2, Spn B, and Spn D) and two paralogs from Homo sapiens (hsRad51 D and dmRad51 D) and their interactions.

Annotation:

Many rivers are affected by man-induced regulations of stream-flow. The effects of these on the instream biota have been studied widely and it is generally accepted that assessment tools for the management of regulated rivers are of vital importance. In particular predictive instream habitat models like the Physical Habitat Simulation Model (PHABSIM) have become popular for this purpose with users world-wide. These models predict discharge-related changes in instream habitat availability for target species by modelling the hydraulic geometry of the river reach on the one and the microhabitat preferences of the species on the other side. Despite their popularity, validation studies for this approach have met many difficulties which are mostly related to the biological part of the model, the habitat preference curves. A review of these studies undertaken here reveals that very little information has been published on two main assumptions of the models: 1. The habitat preference of a species is independent of stream discharge 2. The habitat preference of a species is independent of the species population density Most validation studies are undertaken in field situations. As such they frequently have had problems relating to sampling the microhabitat use consistently, a lack of experimental control and variations in other secondary variables. It was thus decided to conduct controlled experiments in a large indoor flume. Young-of-year Atlantic salmon (Salmo salar) caught in a nearby stream were stocked into pool-riffle sequences, landscaped within a natural substrate, in observation areas of 3.6 metres length and 1 metre width. Microhabitat use of fish was recorded at three different discharges within a 15-fold discharge variation. It was found that the mean column velocity preference of the juvenile salmon, calculated by the standard method, varied largely, mainly due to a shift of preference for low water velocities. "Weighted usable area" (WUA) calculations, the final output of instream habitat models, varied up to two-fold due to these differences in preference. Habitat preference also varied with population density. Fish preferred the riffle habitat at low population density and the pool habitat during high population density. Fish used higher mean column velocities during low population density. There are hence fundamental problems related to the approach of using density functions as preference indices as is commonly done for building habitat preference curves, because of a bias for habitat availability. A new approach using Geographic Information Systems (GIS) is taken by comparing the microhabitat conditions fish experience at their chosen positions with the conditions fish would have experienced had they maintained the positions used at the other discharges. It was found that fish adjusted their positions towards significantly different microhabitats between low flow positions and the positions at the other two flows. This research demonstrates how microhabitat use and preference of wild-caught juvenile salmon varied with discharge and population density in a large near-natural flume. The error introduced by these variations to instream habitat model predictions was large. It confirms that habitat preference curves built as density functions on empirical fish observation data are bound to misrepresent the overall habitat requirements of a species life stage which in the case of juvenile salmon appeared wide and flexible over the range of discharge.

Annotation:

Compassion meditation is a form of mental training that cultivates compassion towards oneself and other people, and is thought to result in greater prosocial behavior in real-world settings. This framework views compassion as a quality that can be trained, rather than a stable trait, and scientists have started testing these hypotheses using neuroscientific and objective behavioral methods. How does this internal meditative practice translate to external behavioral changes? We propose an emotion-regulation model of compassion meditation, where responses to suffering may change through three processes: (1) increasing empathic responses, (2) decreasing avoidance responses, and (3) increasing compassionate responses to suffering. These altered responses to suffering may lead to behavioral transfer, where prosocial behavior is more likely to occur, even in a non-meditative state. We summarize the neuroscientific and behavioral literature that may provide early support for this model, and make recommendations for future research to further test the model.

Annotation:

Suicide is a uniquely human phenomenon, necessitating a human response. Suicide disproportionately claims the lives of older adults, and men in particular. Effective clinical practice with at-risk older adults requires sensitivity to contributing developmental, intrapersonal, social, and existential factors. Whereas the presence of suicide thoughts and behavior may be conceptualized as potential signs of an incipient mental health emergency, demanding quick and decisive action, working clinically with at-risk older adults nevertheless extends temporally beyond moments of behavioral crisis and conceptually beyond risk assessment and management. The field of later-life suicide prevention is in its relative infancy; however, progress is being made in investigating associated risk and resiliency factors and in developing, testing, and disseminating approaches to assessment and intervention. We provide an overview of the literature and call for a more sensitive, compassionate, and effective approach to suicide prevention among older adults, drawing on individually tailored and humanistic-existential approaches to care.

Annotation:

Impulsivity represents a complex multidimensional construct that may change across the lifespan and is associated with numerous neuropsychiatric disorders including substance use disorders, conduct disorder/antisocial personality disorder, and traumatic brain injury. Multiple psychological theories have considered impulsivity and the development of impulse control, inhibition, and self-regulatory behaviors during childhood. Some psychoanalytic theorists have viewed impulse control and self-regulatory behaviors as developing ego functions emerging in the context of id-based impulses and inhibitory pressures from the superego. Object relationists added to this framework but placed more emphasis on mother–child dyadic relationships and the process of separation and individuation within the infant. Cognitive and developmental theorists have viewed impulse control and self-regulation as a series of additive cognitive functions emerging at different temporal points during childhood and with an emphasis on attentional systems and the ability to inhibit a prepotent response. Commonalities exist across all of these developmental theories, and they all are consistent with the idea that the development of impulse control appears cumulative and emergent in early life, with the age range of 24–36 months being a formative period. Impulsivity is part of normal development in the healthy child, and emerging empirical data on normative populations (as measured by neuropsychological testing batteries, self-report measures, and behavioral observation) suggest that impulse control, self-regulation, and other impulsivity-related phenomena may follow different temporal trajectories, with impulsivity decreasing linearly over time and sensation seeking and reward responsiveness following an inverted U-shaped trajectory across the lifespan. These different trajectories coincide with developmental brain changes, including early maturation of subcortical regions in relation to the later maturation of the frontal lobes, and may underlie the frequent risk-taking behavior often observed during adolescence.

This chapter focuses on report writing and testimony as part of disability evaluation. More specifically, it explains how to organize a report, what information should (and should not) be included, the required level of detail, and the effective response to referral questions. It also highlights the importance of accurate communication of information. The chapter first discusses the purpose of a written report in evaluations of disability and the organizational structure of the forensic report before turning to the information that must be included in the evaluation report. It presents an example of a format divided into the following sections: introduction, procedures, summary of records reviewed, behavioral observations and mental status data, clinical interview, data from psychological or neuropsychological testing, collateral contacts, formulation of opinions, and answers to referral questions. Finally, the chapter describes how the written report can form the basis for testimony in court or in an administrative hearing.

Assessing Negative Response Bias in Competency to Stand Trial Evaluations provides a comprehensive guide to assessing malingering, feigning, poor effort, and lack of cooperation in competency to stand trial (CST) examinations. It draws on both the author’s extensive experience as a CST examiner and the vast, dynamic professional literature from forensic psychology, clinical psychology, and neuropsychology on assessing response style. The assessment process is considered from beginning to report writing and testimony, with tips regarding interview strategies, fact patterns and behaviors suggestive of feigning, testing, and creative and ethical use of collateral data. Every major validity test used by CST examiners is thoroughly and critically reviewed, as are others that are promising and not yet widely adopted. This includes self-report inventories such as the MMPI-2, MMPI-2-RF, PAI, and SIMS; structured interviews like the SIRS, SIRS-2, and M-FAST; performance validity tests like the TOMM, VIP, 15 item Test, and WMT; and CST-specific tests like the ILK and ECST-R Atypical Presentation Scales. A complete chapter is devoted to means to summarize and combine data from different tests and sources, and another to special populations such as defendants who claim amnesia, are intellectually disabled, or are adolescents. Report writing and testimony considerations are discussed in detail, with implications for the assessment and practice. In Chapter 10, CST examiners’ practices, including preferences for tests and collateral sources, are reported along with the perceived prevalence of various invalid presentation styles. Finally, policy implications of feigning and suggestions for cost-effective practice are provided.

This chapter describes the challenges that are unique to the assessment of the young child. A preschool child may not respond to standardized testing in a predictable way. A solid understanding of the developmental patterns of young children is necessary to accurately interpret evaluation results. The difficulties inherent in this process are described, as well as the benefits. The domains of the assessment process are outlined, including cognitive and learning ability, preacademic skill development, motor skills, and speech and language development. Issues related to behavior and attention are also addressed. Various approaches to preschool assessment are presented, including observational approaches in the natural setting as well as standardized testing, outlining benefits and cautions when working with this population.

The chapter builds on historical research to elucidate the social and legal status and the everyday lives of women of all classes, aspects that informed fiction about women and their representation, and influenced women who wrote (or did not write) fiction, poetry, and diaries. The chapter examines the interrelation of fictional models/behavioral types and historical and fictional actors. With changing educational opportunities, sexual norms, and social roles, women in literature respond differently to patriarchal norms of society, and the chapter compares gendered identity formation of heroes and heroines and surveys types of heroines, such as mothers, wives and mistresses, fallen women and temptresses. Political novels and novels of adultery, with their sense of freedom and punishment, show women testing boundaries, from extreme cases such as terrorists down to the quotidian yet surprisingly ambivalent role of the mother in Russian nineteenth-century literature.

AbstractTourism and hospitality crises that are extensively discussed online are damaging to organizational image and reputation; therefore, choosing effective response strategies is of paramount importance for service providers. The online discussions data from six hospitality and tourism related crises were used to test which crisis and media coverage characteristics significantly affected the public’s emotional and behavioral reactions to crises. With reference to the attribution theory and the situational crisis communication theory, this study identified the potentially influential crisis characteristics, hypothesized their relationship with variables describing consumer reactions to crises, and then tested those relationships in a series of ANOVA and hierarchical regression analyses. Results indicated that the locus of control, crisis stability, attribution of organizational responsibility, and organizational response strategy affected the public’s cognitive and emotional responses to crises most strongly. The attractiveness and goodwill of media sources also had an effect, as well as the quality and fairness of messages. This study makes a methodological contribution to tourism research by training machine-learning classifiers prior to conducting hypothesis testing. Identifying the most influential factors affecting the public’s response to crises can serve as guidelines for tourism and hospitality organizations in monitoring the spread of online crisis discussions and developing the most appropriate response in order to minimize consumers’ negative emotions that affect online and off-line behavior toward the organization and its brand.

AbstractThis chapter presents an approach for the online optimization of collaborative embedded systems (CESs) and collaborative system groups (CSGs). Such systems have to adapt and optimize their behavior at runtime to increase their utilities and respond to runtime situations. We propose to model such systems as black boxes of their essential input parameters and outputs, and search efficiently in the space of input parameters for values that optimize (maximize or minimize) the system’s outputs. Our optimization approach consists of three phases and combines online (Bayesian) optimization with statistical guarantees stemming from the use of statistical methods such as factorial ANOVA, binomial testing, and t-tests in different phases. We have applied our approach in a smart cars testbed with the goal of optimizing the routing of cars by tuning the configuration of their parametric router at runtime.

Temperament is a complex behavioral trait that describes characteristic patterns of response to environmental, particularly social, conditions and perturbations. Disparities in the tendency to approach or avoid novelty or readiness to engage in aggressive interactions have been documented in comparisons between species (Christian 1970), subspecies (Gonzalez et al. 1981), populations within species (Champoux et al. 1994), inbred lines of laboratory animals (Scott and Fuller 1965), domesticated versus wild populations (Price 1984), and individuals within a species (Benus et al. 1992). Differences in physiological stress response systems (Selye 1937) are commonly identified as an important proximate mechanism underlying these temperament differences (Huntingford and Turner 1987, Kagan et al. 1988). Social systems of animals are perceived as emerging from relationships between individuals (Hinde 1983). Individual interactions, in turn, are hypothesized to reflect individual behavioral strategies which maximize inclusive fitness (Silk 1987). Selection on a physiological system, which can dramatically affect the pattern and outcomes of individual interactions, could produce evolutionary change in social organization and social behavior. Many workers explicitly suggest that temperament differences among primate species are adaptive in many instances, yet admit that the specific ecological and social selection pressures to which the neuroendocrine system is responding are often unclear (Thierry 1985, Clarke et al. 1988, Richard et al. 1989). Species-level comparisons have not offered many testable comparative models, probably because of confounding effects such as large phylogentic distances or uncertain phylogeny, inadequate knowledge of ecological and social conditions in the wild, drift, and convergent evolution. In short, little progress has been made toward understanding the evolution of stress-response patterns in primates. In this chapter I suggest that comparisons of geographically and genetically separated primate populations or subspecies may be an alternative and more successful approach to addressing the evolution of stress responses and the disparate social behaviors that result. Population and geographic comparisons are likely to be profitable for three reasons: (1) comparisons are less likely to be confounded by phylogenetic disparities (Arnold 1992), (2) the factors imposing different selective regimes among localities can perhaps be more readily identified, (3) hypothesis testing may be facilitated because populations suitable for testing a model will be easier to identify than new species.

This chapter provides an overview of the use of IPT for patients with eating disorders. The most common eating disorders are anorexia nervosa, bulimia nervosa, and binge eating disorder. The chapter discusses the adaptations of IPT that have been used for the treatment of eating disorders and evaluates their performance in research studies. The assumption for testing IPT with eating disorders is that they occur in response to distress at poor social and interpersonal functioning and consequent negative mood, to which the patient responds with maladaptive eating behaviors. For anorexia nervosa, few data provide evidence for the benefit of IPT. For bulimia and binge eating disorder, however, IPT is considered a viable option for treatment and is recommended in numerous guidelines. A case example of a woman with bulimia nervosa is provided.

In a context of hyper connectivity, the designers of commercial websites are constantly seeking to generate favorable psychological states among internet users and to re-enchant them. This research aims to study the effect of the interaction between the social dimensions of interactivity on psychological states and the approach behavior of the e-consumer. Experimentation is chosen as the most appropriate method for testing the proposed model. An online experiment was conducted with 662 internet users. A merchant website was designed for the purposes of the study incorporating the interaction forms investigated. The results of this research underline the power of the social dimension of interactivity in the mediated market environments and show that a socially interactive site can generate the user's flow state, as well as a feeling of being physically present in a remote environment. This relation is moderated by the perceived risk.

This chapter investigates correlations between learning theory and outcomes. Based on the hypotheses that in university pedagogy the assessment strategy should be interrelated with desired learning outcomes of the student, it is clear that assessment directly impacts student minds and behavior. Therefore, within the global context of assessment, measurement, and testing strategies, this chapter critically explores novel educational assessment methodology as a response to the following research questions: What are the main issues, controversies, and problems in the educational assessment? What are the most effective solutions for the development of life-long competence through an affordable assessment strategy? This study presents insights into the assessment theory concerning deviations in the acquisition settings between training and testing. It also provides an outlook for the potential of transfer assessment methodologies to metacognitive training of a particular target group.

The purpose of this chapter is to determine the factors influencing the online consumer buying behavior towards essential oils in Penang as there is dissonance between what the consumers want and what has been made available in the purchase of essential oils. There are four factors influencing the online consumer buying behavior that are being evaluated in this research which are brand image, price, quality, and online advertisement. Past literatures have been reviewed on the factors to understand consumers' preferences that leads to consumer buying decision. This study adopted the theory of reasoned action (TRA) as the grounded theory. Questionnaires will be used to collect consumers' response for further testing and analysis to test the relationship and strength of factor variables by using the outlined research methodology.

Abstract The aerospace propulsion industry has seen strides in the use of the additive manufacturing (AM) technology in the rapid prototyping and geometric design flexibility of aerospace parts, with concurrent efforts on 3D printing turbine engine blades of Inconel 718 material [1] for use in aircraft engines. The tensile, compressive and axial fatigue response of AM Inconel 718, along with associated constitutive modeling of the material response exhibited under these mechanical test conditions have been reported. However, in addition to understanding the axial behavioral response exhibited by this material, assessing the role of cyclic shear stresses, through experimental testing and constitutive modeling can provide preliminary insight into the mechanical behavior of AM Inconel 718 under multiaxial loading conditions. This study has presented a novel approach to constitutively model the experimental cyclic shearing deformation of as-built direct metal laser sintered (DMLS) Inconel 718, manufactured along varying build orientations in the xy, yz and xz planes, compared with wrought annealed Inconel 718. Specimens were subjected to completely reversible torsional fatigue tests at room temperature, under angle of twist control. The experimental cyclic shearing response was modeled through the use of the Chaboche model, from which optimized constants are reported with build orientation; and the specimen deformation, under angle of twist control, was captured through a finite-element simulation model of the cylindrical gauge section of the specimens. Overall this study yields a comprehensive understanding of the experimental and modeled cyclic shearing response of an additively manufactured metal, which is vital to develop these components to be conducive for the multiaxial fatigue conditions to which they are subjected to in the gas turbine industry.

The constitutive response of glassy polymers is characterized by their complex thermo-mechanical behavior such as strain rate and temperature sensitive yielding, softening at small strains and re-hardening at large strains. These complex behaviors trigger strain localization in the deformation of polymers. Since localization can be induced by both structural and material instabilities, careful analysis needs to be performed to investigate the localization behavior of polymer specimen testing. Localization such as neck formation and propagation that typically occurs in the tensile and compressive testing of polymers and plastics makes it difficult for experimentalists to extract their intrinsic constitutive response. This problem is exacerbated when localization occurs with shear bands. In this study, a macromolecular constitutive model for polymers showing small-strain softening and large-strain directional hardening is employed to investigate the effect of localization in tension onto the constitutive identification process. Considering the complex interplay between the structural and constitutive instabilities, a method based on direct, real-time measurement of area reduction at the neck section has been proposed to extract the intrinsic constitutive response of polymer materials.

In this study, two types of indentation tests were used for the observation of deformation behavior of biological soft tissue, because indentation testing is an easy method to manage observation and control of the condition of complex tissue specimens. First, a fundamental indentation test was used to evaluate quasi-static deformation behavior of soft tissue. In the evaluation of the quasi-static behavior, elasticity, damage, and fracture of the tissue were analyzed from the profile of reaction force during the indentation. Ball-impact testing with subsonic indentation velocity was used for the evaluation of dynamic behaviors of soft tissue. In the impact test, the viscoelastic characteristics of specimens were evaluated by analyzing stress response, using extended Hertzian contact theory and wave equations, at the moment when a simple ball bullet shot from an airsoft gun strikes the specimen. In the experimental results of the test, an obvious relationship between quasi-static and impact responses of the specimen were observed subjectively. The results are evaluated to analyze the damage and the fracture of the soft tissue for the objective formulation of tissue mechanics. The plateau behavior of reaction force in relation to stress response was also reviewed, in order to quantify the beginning of tissue fracture.

Understanding the mechanical response of brain tissue to dynamic loading conditions is critically needed for the development of realistic brain injury models. The characterization of the tissue behavior via mechanical testing and numerical modeling remains, however, challenging because of the strongly nonlinear time- and strain-dependencies inherent in the tissue response. While several studies [1–4] have uncovered some essential features of this response, the integration of all these features — nonlinearities, hysteresis, volumetric behavior — into one single constitutive framework remains an area of active research [5].

This paper describes a data reduction methodology for eliminating the systematic aberrations introduced by the unwanted behavior of a multiaxial testing machine, into the massive amounts of experimental data collected from testing of composite material coupons. The machine in reference is a custom made 6-DoF system called NRL66.3 and developed at the NAval Research Laboratory, that consists of multiple sets of hexapod configurations essentially forming a recursive synthesis of multiple parallel mechanisms. Hexapod linkages, the grips, and other deformable parts of the machine absorb energy. This is manifested in an either reversible or irreversible manner, thus introducing a parasitic behavior that is undesirable from the perspective of our ultimate goal of the material constitutive characterization. The data reduction focuses both on the kinematic (pose of the grip) and the reaction (forces and moments) that are critical input quantities of the material characterization process. The kinematic response is reduced by exploitation of the kinematics of the dots used for full field measurements. A correction transformation is identified by solving an inverse problem that minimizes the known displacements at the grips as given by the full field measurements and those given by the machine’s displacement sensors. A Procrustes problem formalism was introduced to exploit a known material behavior tested by the testing machine. Consequently, a correction transformation was established and was applied on the load cell data of the machine in order to eliminate the spurious responses appearing in the force and moment data.

A new class of advanced composite materials namely the fibermetal laminates (FMLs) such as ARALL (Aramid Reinforced Aluminum laminate) and GLARE (Glass Reinforced Aluminum laminate) has been developed for primary load bearing components of aircraft fuselage and wings. The FML is composed of alternating layers of fiber reinforced polymer (FRP) and aluminum sheets and shows good fatigue resistance. The metal layers are placed on the top and bottom of the laminate to provide good impact resistance and resistance to extreme environments (moisture, ultraviolet radiation and solvent). Krishnakumar (1994) has provided a survey of extensive works on manufacturing, testing, and modeling of the FMLs. The FMLs exhibit nonlinear viscoelastic and/or plastic behaviors due to the existence of FRP and metal alloy layers. The nonlinearity and time-dependent responses in the FMLs are intensified under high load levels, elevated temperatures, and humid environments. A predictive capability on the overall nonlinear viscoelastic response of the FMLs that recognizes different responses in the FRP and metallic layers becomes necessary. Literature indicates a few advances in this direction by the consideration of the elastic-plastic behavior and the use of classical lamination theory (Chen & Sun, 1989; Hashagen et al., 1995). Pindera et al. (1989) have carried out an experimental investigation of the creep response of ARALL laminates at 121°C. A pronounced viscoelastic behavior is observed in ARALL at stress levels below its proportional limit. Aluminum exhibits a nonlinear viscoelastic behavior while aramid-FRP shows a linear viscoelastic behavior. The classical lamination theory (CLT) was used to model the overall creep response of the laminates.

The biomechanical response of abdominal aortic tissue to uniaxial loading conditions has been reported previously [1]. This testing identified the uniaxial mechanical response of aortic tissue to specimens oriented in the longitudinal and circumferential directions, but did not provide significant evidence for the isotropy or anisotropy of this tissue. The information taken from uniaxial tensile testing is insufficient for the characterization of the multi-axial mechanical response of aortic tissue. In particular, the uniaxial response of a biological tissue in a given direction does not incorporate the effects of loading in an orthogonal direction. For these reasons, there exists a need for an enhanced description of the mechanical response of aortic tissue to loading in multiple planar directions. For the current investigation, biaxial tensile testing was performed on normal abdominal aortic tissue in order to gain insight into the anisotropy and age related differences of the biomechanical response of this tissue.

Abstract Application of the free-suspension residual flexibility modal test method raises some interesting issues and problems for the correlation of finite element models to test data. This paper presents a discussion of some of those issues as related to testing and analysis of two structures. One of these test articles is the International Space Station Pathfinder, a large structure similar in size and weight to the Space Station Resource Node. The approach used by the authors to correlate models to residual flexibility data is presented, along with mode shape and frequency response results which illustrate the structural dynamic behavior of the models before and after the updating process. Frequency response functions (FRF) for the regions of the structure that interface with the environment (a test fixture or another structure) are shown to be the primary tools for model correlation that distinguish or characterize the residual flexibility approach. A number of critical issues related to use of the structure interface FRF for correlating the model are then identified and discussed, including (1) the requirement of prominent stiffness lines, (2) overcoming problems with measurement noise which makes the antiresonances or minima in the functions difficult to identify, and (3) the use of interface stiffness and lumped mass perturbations to bring the analytical responses into agreement with test data. It is shown that good comparison of analytical-to-experimental FRF is the key to obtaining good agreement of the residual flexibility values.

The integrity of components can be affected by certain material degradation mechanisms that cause a loss of ductility. In cases where the component loading is primarily in bending, a loss of ductility can significantly reduce the load capacity. Material degradation may be determined by component testing involving the bending mode. In such cases, characterizing the material response in terms of yield stress, ultimate stress and failure strain is complicated by the nature of the load curve due to bending. The objective of this work is to examine in detail the relationship between tensile and bending response, with particular attention to the condition of decreasing ductility.

The solution to many engineering problems is obtained through the combination of analytical, computational and experimental methods. In many cases, cost or size constraints limit testing of full-scale articles. Similitude allows observations made in the laboratory to be used to extrapolate the behavior to full-scale system by establishing relationships between the results obtained in a scaled experiment and those anticipated for the full-scale prototype. This paper describes the application of the Buckingham Pi theorem to develop a set of non-dimensional parameters that are appropriate for describing the problem of a distributed load applied to the rostrum of the paddlefish. This problem is of interest because previous research has demonstrated that the rostrum is a very efficient structural system. The ultimate goal is to estimate the response of a complex, bio-inspired structure based on the rostrum to blast load. The derived similitude laws are verified through a series of numerical experiments having a maximum error of 3.39%.
