An identifiable model of two-stage learning

An eleven-parameter model for two-stage learning is developed. The model's principal advantage over extant two-stage models is that its parameter space is completely identifiable, thereby eliminating the tedious procedure of locating acceptable identifying restrictions. Identifiability is achieved by defining the model over a slightly modified outcome space. Following the identifiability proof, the necessary statistical machinery for parameter estimation, goodness-of-fit analyses, and hypothesis testing is presented. These latter developments are illustrated with data from an adult cued recall experiment and a free recall experiment with elementary school children.     

The given-new structure of cleft sentences and their influence on picture viewing

Summary In three experiments the influence of the given-new structure of cleft sentences on picture viewing was examined. Subjects heard cleft sentences and subsequently inspected pictures depicting the agent and the patient of the action mentioned in the sentence. Each sentence-picture pair was preceded by an adequate context sentence and a context picture. It was demonstrated that the delineation of the agent or of the patient in the sentence was looked at longer when it was marked as new information in the sentence that described the picture than when it was marked as old information. We interpret these findings to mean that the new information of a cleft sentence sets up a focus of attention in the cognitive structure and that this prolongs the time spent in the inspection of a delineation of the focal concept.     

Some studies on the internal structure of propositions

Summary Five experiments were carried out to test the information processing of the propositional arguments instrument and beneficiary. Proceeding from the assumption that propositions are basic units of memory, it was hypothesized that instrument and beneficiary would show different effects in recall experiments, depending on whether they were components of appropriate propositions or not. Experiments I and II were conducted to test this assumption. The results showed that things are more complicated than was expected. Besides propositional structure, the semantic integration of concrete propositions has to be taken into account to predict their psychological processing. Experiments III, IV, and V were conducted to prove this. On the whole, it was found that instruments can always be considered as arguments but beneficiaries only when they are obligatory; and further that in general instrument arguments are semantically more strongly implied by their predicates than beneficiary arguments are.I would like to thank Trevor Scott for his help in writing the English text.

Putting a Price tag on Healthy Behavior: The Monetary Value of Sports Participation to Individuals

This study estimates the monetary value of sports and physical activity applying the compensation variation method. While previous studies put a price tag on various health conditions, this study assigns a monetary value to healthy behavior, such as participation in sports and physical activity. Data from the German Socio-Economic Panel (1992–2013) are used for the analysis (n = 191,828). A generalized ordered response model is estimated to take the heterogeneity in the dependent variable, a single-item life satisfaction measure, into account. The results show that females (males) would be willing to forgo between €195 and €840 (€330 and €790) of their monthly net income in order to participate in sports and physical activity several times a year. A higher frequency of participation is associated with higher monetary values: females (males) are willing to forgo between €552 and €1281 (€491 and €1483) of their monthly net income to participate in sports or exercise at least once a month and between €577 and €1471 (€577 and €1662) to participate at least once a week, respectively, compared to not participating at all. Evidently, participation in sports and physical activity improves individuals’ life satisfaction and is of substantial value to individuals. The findings have implications for health economists, policy makers, and the courts. This study contributes to the literature examining the relationship between sports participation and well-being.     

Lack of free choice reveals the cost of multiple-target search within and across feature dimensions

Having to look for multiple targets typically results in switch costs. However, using a gaze-contingent eyetracking paradigm with multiple color-defined targets, we have recently shown that the emergence of switch costs depends on whether observers can choose a target or a target is being imposed upon them. Here, using a similar paradigm, we tested whether these findings generalize to the situation in which targets are specified across different feature dimensions. We instructed participants to simultaneously search for, and then fixate, either of two possible targets presented among distractors. The targets were defined as either two colors, two shapes, or one color and one shape. In one condition, only one of the two targets was available in each display, so that the choice was imposed. In the other condition, both targets would be present in each display, which gave observers free choice over what to search for. Consistent with our earlier findings, switch costs emerged when targets were imposed, whereas no switch costs emerged when target selection was free, irrespective of the dimension in which the targets were defined. The results are consistent with the operation of different modes of control in multiple-target search, with switch costs emerging whenever reactive control is required and being reduced or absent when displays allow for proactive control.     

Axiomatic Theories of Partial Ground I

This is part one of a two-part paper, in which we develop an axiomatic theory of the relation of partial ground. The main novelty of the paper is the of use of a binary ground predicate rather than an operator to formalize ground. This allows us to connect theories of partial ground with axiomatic theories of truth. In this part of the paper, we develop an axiomatization of the relation of partial ground over the truths of arithmetic and show that the theory is a proof-theoretically conservative extension of the theory PT of positive truth. We construct models for the theory and draw some conclusions for the semantics of conceptualist ground.     

Combining Value‐focused Thinking and Balanced Scorecard to Improve Decision‐making in Strategic Management

Goal orientation is key to strategic management. In this field, the Balanced Scorecard is one of the most widely used management tools. It structures a company's main objectives from different perspectives based on the strategy of the firm and uses performance indicators to measure the achievement of objectives and strategy. However, its method of creation is not theoretically sound. Value‐focused thinking is a decision‐making philosophy that fits perfectly with Balanced Scorecard creation. It provides methods and techniques for the identification and structuring of objectives that are suitable to systematically derive a scorecard from a means‐ends network. However, such a means‐ends network is often too complex for enduring use in strategic management. By adapting the network's structure to the Balanced Scorecard's layout, the profound and clear set of derived objectives and their measures serve as a reasonable basis for applying methods of multi‐criteria decision‐making in an organization. This paper aimed to outline a procedure that merges the Balanced Scorecard and value‐focused thinking by preserving each concept's strengths while eliminating their weaknesses. A six‐step process was developed theoretically and employed empirically in a case study. This process included (1) identifying objectives; (2) structuring objectives; (3) characterizing clusters of objectives; (4) formulating mission, vision, and strategy; (5) designing the scorecard; and (6) monitoring and adapting to change. On the basis of this approach, a Management Scorecard was produced that enabled strategy development and execution, put forth a clear and comprehensive means‐ends network, and visualized a company's most important objectives and their relationships structured through perspectives roughly following the Balanced Scorecard. It acts as a foundation for research to generalize and compare findings regarding goals of organizations. Our procedure demonstrates how scientific methods, such as value‐focused thinking, can yield benefits to practitioners' instruments, like the Balanced Scorecard, and how management tools can likewise improve scientific methods.

Children's comprehension of visual formal features in television programs

A review of previous studies on children's comprehension of visual formal features did not warrant predictions about children's understanding of the formal features as used in three items from Sesamstraat, the Dutch version of Sesame Street. Therefore, a study was designed in which 45 children in the age range of 4–6 years watched the items and were interviewed. In the first item, a split screen was used to visualize simultaneity of actions. The second item used a subjective camera to suggest the construction of a home video by one of the characters. Version 1 of this item did not show the character while making home video, whereas Version 2 did show the character while filming. The third item contained a dissolve (Version 1) or a cut (Version 2) to indicate the end of a dream. A general conclusion was that although older children (mean AGE=5.9 years) understood the visual formal features better than younger children (mean AGE=4.4 years), the extent to which children in both age groups understood the visual formal features appeared to vary between items and versions. Most children in both age groups understood the split screen in the first item. The younger age group did not understand the subjective camera if the making of the home video was not shown. Both the younger and the older age group understood the version with the cut better than the original version with the dissolve. In the discussion, the question was addressed what the findings of this study and previous studies teach us about children's understanding of visual formal features in general.     

Leadership predictors of innovation and task performance: Subordinates' self‐esteem and self‐presentation as moderators

This study examined self‐related subordinate variables as moderators of relationships between supervisors' leadership behaviours (transformational as well as active‐corrective transactional leadership) and subordinates' innovative behaviour and task performance. Based on behavioural plasticity and self‐monitoring theory, we hypothesized that these associations would be moderated by subordinates' organization‐based self‐esteem and by their propensity to modify self‐presentation, a major facet of the self‐monitoring construct. Field survey data (N=161) collected in research and development, marketing and human resources departments of several German companies revealed that transformational leadership positively predicted both criteria, whereas active‐corrective transactional leadership negatively predicted innovation. As hypothesized, transformational leadership related more strongly and positively to innovation for subordinates low in organization‐based self‐esteem. When subordinates were low in self‐presentation propensity, active‐corrective transactional leadership was negatively, and transformational leadership was positively associated with task performance.     

Three preparatory studies for promoting implementation of outpatient schema therapy for borderline personality disorder in general mental health care

ObjectiveThree studies were conducted to prepare for the implementation of Schema Therapy (ST) for Borderline Personality Disorder (BPD) in general mental healthcare settings. Two were surveys to detect promoting and hindering factors, one was a preliminary test of a training program in ST.MethodsIn 2004, a diagnostic analysis of factors promoting and hindering implementation of a new treatment for BPD was conducted among both managers (n = 23) and therapists (n = 49) of 29 Dutch mental healthcare institutes through a written survey (Study 1). Next, a training program, including a set of DVDs displaying the major therapeutic techniques, was developed and tested among eight therapists. The training program was evaluated by the participants. After the training, three independent raters evaluated therapists' adherence and competence, viewing videos of the therapists completing structured role-plays (Study 2). In 2008, a second written survey was conducted in 22 mental health institutes to study factors for future nationwide implementation of ST (Study 3).ResultsBoth surveys indicated that the situation in most institutes was favorable for implementing a new effective treatment, as participants were not satisfied with the existing treatments, had suitable professional backgrounds, worked in settings with (B)PD-oriented care programs, and expressed a need for change. The surveys yielded clear results for promoting or hindering successful implementation of ST. Promoting factors included scientific evidence for the effectiveness of the treatment, structural changes in the patient's personality, rapidly noticeable effects for the patient, low drop-out rates and a favorable cost-effectiveness. Possible barriers included implementation mandated unilaterally by management, choosing ST based on financial or organizational needs, extending implementation over a lengthy period of time and providing telephone support by therapists beyond office hours. The eight-day training program received very positive ratings. After the training, therapists were rated as sufficiently adherent and competent applying ST to treat BPD patients, with peer supervision and supervision recommended as a supplement to the training.ConclusionThis study showed that the situation in 2005 was advantageous to start implementation of ST. Evaluation of the training and the achieved competence scores of trainees concluded that the training program was a good basis for training therapists in ST. Outcome of the survey in 2008 demonstrated that there was a clear interest for implementation of ST for BPD patients in the future.
