The extended model of different forms of work satisfaction ( Büssing, 1991 ), originally proposed by Bruggemann (1974) , is suggested as a distinctive qualitative approach to work satisfaction. Six forms of work satisfaction—progressive, stabilized, resigned satisfaction, constructive, fixated, resigned dissatisfaction—are derived from the constellation of four constituent variables: comparison of the actual work situation and personal aspirations, global satisfaction, changes in level of aspiration, controllability at work. Preliminary evidence from semi-structured interviews with 46 nurses shows that the dynamic model is headed in the right direction (qualitative differentiation of consistently high propertions of satisfied employees, uncovering processes of person-work situation interaction). Qualitative methods demonstrated their usefulness in accessing underlying cognitive and evaluative processes of the forms, which are often neglected by traditional attitude-based satisfaction research.

This paper focuses on processes and consequences of intergroup interactions in plural societies, focusing primarily on majority-minority mutuality in acculturation orientations. We examine commonalities and differences among conceptualizations and models addressing issues of mutuality. Our review includes the mutual acculturation model ( Berry, 1997 ), the Interactive Acculturation Model (IAM – Bourhis et al., 1997 ), the Concordance Model of Acculturation (CMA – Piontkowski et al., 2002 ); the Relative Acculturation Extended Model (RAEM – Navas et al., 2005 ), and the work on acculturation discrepancies conducted by Horenczyk (1996 , 2000 ). We also describe a trend toward convergence of acculturation research and the socio-psychological study of intergroup relations addressing issues of mutuality in attitudes, perceptions, and expectations. Our review has the potential to enrich the conceptual and methodological toolbox needed for understanding and investigating acculturation in complex modern societies, where majorities and minorities, immigrants and nationals, are engaged in continuous mutual contact and interaction, affecting each other’s acculturative choices and acculturative expectations.

Abstract The first part of this paper outlines the relevant aspects of functional structuralism serving lexicographers as a departure point for building a model of lexical meaning useable in the Dictionary of Contemporary Slovak Language. This section also points to some aspects of Klára Buzássyová’s research on lexis and word­formation that have enriched the functional­structuralist paradigm. The second section shows other theoretical and methodological frameworks, such as linguistic pragmatics, cognitive linguistics and corpus linguistics (all of them departing in some respect from the structuralism and, in other aspects, being complementary with it) that can enhance the structuralist basis of the model. The third section outlines an extended model of lexical meaning that represents a synthesis of all those theoretical frameworks and, at the same time, represents a reflection of three language constituents: 1. The social constituent is present in consideration of communicative functions of utterances, naming functions of lexical units, functional styles and registers, language norms, and situational contexts; 2. The psychological component takes the form of consideration of the prototype effect, the abolition of boundaries between linguistic meaning and other parts of cognition; 3. Thanks to the structural/systematic component, a description of paradigmatic and syntagmatic behaviour of words can be performed, and an inventory of formal­content units and categories (lexemes, lexies, word­forming and grammatical structures) can be provided. In our dictionary practice, the above­mentioned model is reflected in the methodological procedures as follows: 1. Systemization of repetitive (regular, standardized) phenomena; 2. Prototypicalization of meaning description; 3. Contextualization/encyclopedization of meaning description; 4. Pragmatization of meaning description; 5. Continualized presentation of language phenomena, i.e., introduction of numerous phenomena of transient and indeterminate nature and indicating the existence of a semantic­pragmatic and lexical­grammatical continuum; 6. “Discretization” of combinatorial continuum, i.e., identification and description of entrenched word combinations with naming functions.

In this study, the researchers explore the antecedents of tourists’ intention to recommend a destination using an extended Theory of Planned Behavior (TPB). Two personal values (i.e., prosocial and maturity) and two personality traits (i.e., extraversion and agreeableness), which are rarely studied but important elements for marketers to better understand the market (e.g., segment the market), are examined. To test the extended model of TPB, a survey (n=312) was conducted with tourists in Portugal. The researchers find support for the hypothesis that tourists with higher prosocial values, maturity values, and extraversion personality traits are more likely to have a favorable attitude toward a destination and a tendency to recommend the destination. Theoretical and managerial implications are discussed.

Background: Mathematical modeling in modified drug release is an important tool that allows predicting the release rate of drugs in their surrounding environment and elucidates the transport mechanisms involved in the process. Objective: The aim of this work was to develop a mathematical model that allows evaluating the release profile of drugs from polymeric carriers in which the swelling phenomenon is present. Methods: Swellable matrices based on ionic complexes of alginic acid or carboxymethylcellulose with ciprofloxacin were prepared and the effect of adding the polymer sodium salt on the swelling process and the drug release was evaluated. Experimental data from the ciprofloxacin release profiles were mathematically adjusted, considering the mechanisms involved in each stage of the release process. Results: A proposed model, named “Dual Release” model, was able to properly fit the experimental data of matrices presenting the swelling phenomenon, characterized by an inflection point in their release profile. This entails applying the extended model of Korsmeyer-Peppas to estimate the percentage of drug released from the first experimental point up to the inflection point and then a model called Lumped until the final time, allowing to adequately represent the complete range of the drug release profile. Different parameters of pharmaceutical relevance were calculated using the proposed model to compare the profiles of the studied matrices. Conclusion: The “Dual Release” model proposed in this article can be used to predict the behavior of complex systems in which different mechanisms are involved in the release process.
