Streszczenie:

Hebbian heteroassociative learning is inherently asymmetric. Storing a forward association, from item A to item B, enables recall of B (given A), but does not permit recall of A (given B). Recurrent networks can solve this problem by associating A to B and B back to A. In these recurrent networks, the forward and backward associations can be differentially weighted to account for asymmetries in recall performance. In the special case of equal strength forward and backward weights, these recurrent networks can be modeled as a single autoassociative network where A and B are two parts of a singl

A central tenet of Rescorla and Wagner’s model of associative learning is that the reinforcement value of a paired trial diminishes as the associative strength between the presented stimuli increases. Despite its fundamental importance to behavioral sciences, the neural mechanisms underlying the model have not been fully explored. Here, we present findings that, taken together, can explain why a stronger association leads to a reduced reinforcement value, within the context of eyeblink conditioning. Specifically, we show that learned pause responses in Purkinje cells, which trigger adaptively

In a partial reinforcement schedule where a cue repeatedly predicts the occurrence of a target in consecutive trials, reaction times to the target tend to decrease in a monotonic fashion, while participants’ expectancies for the target decrease at the same time. This dissociation between reaction times and expectancies—the so-called Perruchet effect—challenges the propositional view of learning, which posits that human conditioned responses result from conscious inferences about the relationships between events. However, whether the reaction time pattern reflects the strength of a putative cue

The McCollough effect (ME) refers to the phenomenon that, after a few minutes' exposure to gratings differing in both orientation and colour, subjects perceive similarly oriented achromatic gratings as if they were tinted with complementary hues. The traditional explanation of the ME as an adaptation of detectors selective for colour and orientation suffers from a number of inconsistencies: (i) the ME lasts much longer than ordinary adaptation, the decay of the effect being completely arrested during a night's sleep, or by occluding the eye for a long time; (ii) the strength of the ME is pract

Rescorla and Wagner’s model of learning describes excitation and inhibition as symmetrical opposites. However, tasks used in human causal learning experiments, such as the allergist task, generally involve learning about cues leading to the presence or absence of the outcome, which may not reflect this assumption. This is important when considering learning effects which provide a challenge to this model, such as the redundancy effect.

Integrate-and-express models of synaptic plasticity propose that synapses integrate plasticity induction signals before expressing synaptic plasticity. By discerning trends in their induction signals, synapses can control destabilizing fluctuations in synaptic strength. In a feedforward perceptron framework with binary-strength synapses for associative memory storage, we have previously shown that such a filter-based model outperforms other, nonintegrative, “cascade”-type models of memory storage in most regions of biologically relevant parameter space. Here, we consider some natural extension

Neural associative networks with plastic synapses have been proposed as computational models of brain functions and also for applications such as pattern recognition and information retrieval. To guide biological models and optimize technical applications, several definitions of memory capacity have been used to measure the efficiency of associative memory.

Magnesium sheet metal alloys have a hexagonal close packed (hcp) crystal structure that leads to severe evolving anisotropy and tension-compression asymmetry as a result of the activation of different deformation mechanisms (slip and twinning) that are extremely challenging to model numerically. The low density of magnesium alloys and their high specific strength relative to steel and aluminum alloys make them promising candidates for automotive light-weighting but standard phenomenological plasticity models cannot adequately capture the complex plastic response of these materials.

Judgments about causality are central to the development of interventions intended to reduce exposure to risk factors that cause cancer. Because causation is not directly observable in medicine, scientists and philosophers have had to develop sets of constructs and heuristics that define “cause” operationally.

AbstractThis research investigates destination imagery of Switzerland as a travel destination. This research first conducted survey and content analysis to identify 23 unique statements reflecting travel in Switzerland. Through an online survey, this research collected 399 responses from French and Italian respondents. Based on the comparisons of association strength and association valence of every statement to the aggregated association strength and association valence, this research developed the Destination Imagery Diagnosis model. The results show that, overall, French and Italian respondents have strong and positive associations to statements related to Switzerland’s nature and opportunities for outdoor activities. Furthermore, respondents rated “Healthy lifestyle” and “Welcoming and friendly” positively but the associations to Switzerland were weaker. This research also identified marketing opportunities specifically for French and Italian respondents. The Destination Imagery Diagnosis Model serves as a new tool to compare destination imageries between markets or keep track of changes of destination imagery.

AbstractThe evident failure of voluntary corporate codes of conduct and their monitoring has further intensified debates over the purchasing practices and legal accountability of transnational corporations. This article analyses the development of International Framework Agreements as an alternative approach advanced by trade unions and describes the characteristics of these instruments, pointing out their strengths and weaknesses concerning implementation and monitoring. It specifically focuses on the Indonesian Protocol on Freedom of Association, a special framework agreement concluded between Indonesian trade unions and international sportswear firms to protect freedom of association and trade union rights in the Indonesian textile, garment and footwear industries. After presenting the protocol’s content, the article discusses findings concerning the implementation and monitoring of the agreement, based on interviews conducted by the author in Indonesia between November 2018 and January 2019. It identifies several key factors that led to the successful promotion of strong trade union rights in the formation phase of the agreement, namely public awareness due to intensive campaigning around a mega sporting event, strong support from different civil society actors and the presence of a neutral facilitator. Overall, the Indonesian Protocol on Freedom of Association is an example of a bottom-up process that strengthens the signatory trade unions and thus serves as a potential model for actors in other countries.

If an intelligent system is to benefit from prior experiences, then such a system must have the ability to learn. Learning must lead to the gathering of new knowledge of increased complexity and is based on the exploration of the world and social interactions. In this chapter authors describe building representations in motivated learning, a process that is close to learning by natural systems and yields better learning results in artificial systems than reinforcement learning. An embodied agent's mission is to survive in an unfavorable environment. The agent must have needs whose fulfillment is a measure of its success – survival. Meeting these needs require physical and mental efforts, and the development of useful skills is associated with the development of intelligence. The agent's environment must provide conditions in which individuals will be subjected to pressure from an environment in which better solutions, greater skills, and broader knowledge count. The agent treats unmet needs as signals to act. The strength of these signals depends on the degree of unmet needs so that the agent can differentiate between them and compared them. Various need signals provide motivation for action and control the learning process. In complex environments, there are rules that regulate the relationships between objects. By discovering these rules, the machine gains knowledge about the environment. Knowledge is represented by building connections between neurons in semantic memory. New concepts, objects, needs, or motor skills are represented by adding new memory cells and by associating them with other concepts, actions, and needs. Whether or not a new object or idea is created in semantic memory depends on the mechanism of novelty detection. The more time an agent spends on working or playing with an object, the better it learns the object's physical properties and how to use it. The intended use of objects determines characteristic features needed to classify them. Initially, semantic memory does not store any concepts, does not know places, does not recognize any objects, and does not support any activities or motivations. New concepts or representations of objects emerge from observation and manipulation of objects. A virtual agent's semantic memory obtains symbolic representations of objects and their location or movement in the observed scene. The focus of perceptual attention may result from detection of novelty, change, movement, signal intensity, or meaning in the context of needs. Attention should be focused long enough for the working memory to evaluate how much observed object or considered plan is useful. The focus of attention must also be accompanied by the possibility of switching attention. The attention switching responds to various types of signals, from sensory stimuli through planning and monitoring of performed activities to associative activation of memory. It results from constant rivalry between these signals for attention.

Why do some events lead to growth in character strengths and others do not? Past research has addressed this question using a typological approach where adversities are grouped into different types or categories (e.g., daily stressor vs. clinical trauma). This approach has practical and theoretical limitations. In this chapter, the authors propose a conceptual model that incorporates a dimensional approach to examining how and why adverse events differ in their impact on character strengths. This conceptual model identifies 10 dimensions of event characteristics (e.g., external control, negative valence). They also explore the association among these event characteristics and character growth with a focus on five central research questions: (1) Which characteristics of adverse events are generally associated with character growth? (2) Which characteristics of adverse events are generally associated with declines in character strengths? (3) Are specific characteristics of adverse events associated with growth in specific character strengths? (4) Does the perception of event characteristics change over time? (5) Is the association between adversity and character strengths bidirectional?

This chapter provides a deeper insight into the concept of a nautical station. More specifically, it tries to determine the importance of partnership models defined by digital platforms as a tool for a cooperation strategy in the development of new products; such is the case of nautical tourism in Portugal, a coastal nation in southwestern Europe. With this objective in mind and framed by the concept of the nautical station as a starting point, a descriptive analysis explores this topic. The case of Spain, with the development of the Nautical Resorts Association, is a model for best practice that must be not replicated but adapted to the situation in Portugal. This chapter advocates that nautical tourism, as a strategic tourist product for Portugal, will gain more prominence and strength if supported by a collaboration model between the various stakeholders of the tourism system framed by partnership models.

The field of positive psychology and psychiatry has the goal of helping people to achieve greater happiness, fostering the factors that allow individuals, communities, and societies to thrive. It proposes a hierarchy of positive psychological character strengths, composed of 24 specific human qualities, including spirituality. Spiritually oriented well-being therapies are a promising and much-needed field. The bio-psycho-social model, developed by Cloninger and colleagues, is an empirically based model that considers the importance of spirituality in the human constitution and development, providing a systematic way to promote health as an integrated state, rather than merely the absence of disease or infirmity. Personality development depends on the creative process of integration through three complex adaptive systems of learning and memory, involving associative conditioning of habits, intentional self-control, and creative processes of self-awareness. The physical, mental, and spiritual aspects are interdependent, and must be addressed jointly aiming at a healthy, happy, and good life.

Its main weaknesses are delayed diagnosis, fragmented care, the use of only a curative model of care, a lack of interdisciplinary team approach, and a lack of non-pharmacological treatments, as well as a lack of communication of diagnoses to patients. In its current format, the health system does not fully guarantee the human rights of people with dementia and their families.

Chapter 4 discusses Walker’s gift of political and social activism and her leveraging of the number and voices of her agents to challenge Jim Crow. In a manner reflective of leading black women’s clubs and fraternal organizations of the day, Madam Walker organized her sales agents into local clubs and a national umbrella association to legitimize beauty culture as a profession, strengthen relations between them, and enlist them in doing charity and advocacy work in their communities that would last long after her death. The National Beauty Culturists’ and Benevolent Association of Madam C. J. Walker Agents, Inc., developed a model of associationalism, ritualism, and activism that galvanized Walker agents to serve their communities and the cause of racial uplift. Through it, agents regularly donated money to black schools and other organizations, held fundraising events, organized programs, and cared for the vulnerable in their communities. Together, they sent a resolution to President Woodrow Wilson demanding legislative action against lynching. The chapter reviews Walker’s unique ability to interact with black women across class differences, as exhibited by her engagement of working-class women in her agent clubs and the elite black women of the era through the National Association of Colored Women (NACW). Through these clubs and their rituals, Walker agents staked claims for themselves as respectable professionals, performed charitable works in black communities, and used their formidable numbers to speak out against lynching and Jim Crow.

The entire test project consists of 34 seamless pipes with a relative low Diameter-to-thickness (D/t) ratio around 21.3, among which four intact specimens and thirty damaged specimens have been carri

Students tend to compartmentalize individual classes throughout their time in school; associating that which is taught in one class with only that class. A finite element class offers a unique opportunity to illustrate the connection between several engineering topics through modeling and experiments since it is used to solve many different types of problems (e.g. force-deflection, stress-strain, heat transfer, fluid transport, and vibrations). In addition, providing hands-on experiments is an excellent way to illustrate concepts. Particularly, experiments can help students visualize the addit

Ultimate strength of the hull girder of containerships became a significant issue in the last years in view of recent accidents and related investigations. Actually, larger and larger ships were put into service and still are designed and built. Recognizing such an issue, investigations were carried out and led to the issuance of a specific longitudinal strength standard for containerships by the International Association of Classification Societies [1]. Loading conditions become more and more challenging and especially combinations of various actions were found to impair the hull girder ultim

Roof intrusion is a major cause of neck injury to belted occupants during rollover accidents. The correlation of reduced head room with increased injury risk has been demonstrated by the National Highway Traffic Safety Administration (NHTSA) and others such as the Insurance Institute of Highway Safety (IIHS). The current FMVSS 216 standard requires the vehicle roof, when loaded with a platen of prescribed geometry and application vector, to resist 1.5 times the vehicle empty weight before deforming 127mm. This standard was developed to ensure a modest level of safety of the vehicle in rollover

The tube-to-tubesheet joint strength is measured in terms of residual contact pressure between the tube’s outer surface and tubesheet hole surfaces. The joint integrity is affected by several design parameters, including the type of tube and-tubesheet materials, level of expansion and the initial radial clearance between the tube and tubesheet. In the present work, an axisymmetric finite element model based on the sleeve diameter and rigid roller concepts is developed. The model has been used to evaluate the combined effects of clearance, wall reduction level and the-strain hardening of tube a
