The purpose of this paper is to operationalise and verify a cognitive motivation model that has been adapted to information seeking. The original model was presented within the field of psychology.

An operationalisation of the model is presented based on the theory of expectancy-value and on the operationalisation used when the model was first developed. Data for the analysis were collected from a sample of seven informants working as consultants in Danish municipalities. Each participant filled out a questionnaire, kept a log book for a week and participated in a subsequent interview to elicit data regarding their information source behaviour and task motivation.

Motivation affected source use when the informants search for information as part of their professional life. This meant that the number of sources used and the preference for interpersonal and internal sources increased when the task had high-value motivation or low-expectancy motivation or both.

The study is based on a relatively small sample and considers only one motivation theory. This should be addressed in future research along with a broadening of the studied group to involve other professions than municipality consultants.

Motivational theories from the field of psychology have been used sparsely in studies of information seeking. This study operationalises and verifies such a theory based on a theoretical adaptation of this model made by Savolainen (2012c).

The purpose of this research is to propose a framework for research on Macaulay duration and establish future research directions.

Thematic, bibliometric and content analyses have been used to review 168 research papers published between 1938 and 2019 taken from ISI Web of Science and Scopus contributed by leading authors, journals and regulatory bodies.

Identification and integration of themes of duration theory, duration model development and duration model implementation leading to unattended research gaps, and framework for research on Macaulay duration.

The study is based on an extensive review of the literature to extract important themes, research gaps and frameworks. It does not empirically investigate significance of Macaulay duration and various sectors.

This research has several aspects that are helpful for practitioners. Macaulay duration has been the subject of empirical research only without any guiding framework. This research provides a platform to initiate profound researches in various areas of finance. Various proposed models are required to be tested under holistic approach in conventional and emerging fields, especially in Islamic settings.

This research highlights, research themes leading to framework, research gaps and factors that are crucial in developing, extending and testing duration models leading to enhancement of theoretical base of Macaulay duration.

Football is deployed into various segments and consists of a complex value chain, with interrelationships and circularities. It is relevant in various segments and therefore it is important to understand the structure. Thus, the purpose of this paper is to present a model of a football value chain and the managerial implications inherent to this chain.

This research used a field study as its methodology, developing a semi-structured questionnaire containing open-ended questions about the representativeness of the football value chain. In-depth interviews with specialists in football were performed to collect data.

The results of the interviews indicated that the theoretical model is representative. Furthermore, through validation, the relevance and representativeness of the football value chain was shown, as well as its interrelationships with the other commodity and service segments. In addition, it was found that this segment is relevant and influential in the national and international market, and can be considered a factor of economic and social development.

This paper provides a view of the actors who make up the football value chain, and also supplies a complementary view to the models of chains presented in the theoretical review, enabling the provision of evidence on the axis with greater added value as a new step. The limitation of this research involves the context approached, because as identified throughout the investigation, this context is complex and dynamic. In this way, the linear approach used to construct this chain led to a reduced view of reality and of present relationships.

The model shows the presence of the main actors and the structure for the transformation of raw material into a final product, and is useful to understand the existing relationships and the layers of added value.

The evaluation of the conceptual model of football value chain confirms that this is a professionalized chain, which generates a significant number of direct and indirect jobs.

The authors propose a model of a football value chain which is complementary to the theoretical review developed, exposing a linkage of the players present in this chain and at what stage they are present, and supplies the managerial implications inherent to this.

The purpose of this paper is to introduce a new agent-based simulation model of bilateral negotiation based on a synthesis of established theories and empirical studies of negotiation research. The central units of the model are negotiators who pursue goals, have attributes (trust, assertiveness, cooperativeness, creativity, time, etc.) and perform actions (proposing and accepting offers, exchanging information, creating value, etc).

Methodologically, the model follows the agent-based approach to modeling. This approach is chosen because negotiations can be described as complex, non-linear systems involving autonomous agents (i.e. the negotiators), who interact with each other, pursue goals and perform actions aimed at achieving their goals.

This paper illustrates how the model can simulate experiments involving variables such as negotiation strategy, creativity, reservation value or time in negotiation. An example simulation is presented which investigates the main and interaction effects of negotiators’ reservation value and their time available for a negotiation. A software implementation of the model is freely accessible at https://tinyurl.com/y7oj6jo8.

The model, as developed at this point, provides the basis for future research projects. One project could address the representation of emotions and their impact on the process and outcome of negotiations. Another project could extend the model by allowing negotiators to convey false information (i.e. to bluff). Yet another project could be aimed at refining the routines used for making and accepting offers with a view to allow parties to reach partial settlements during a negotiation.

Due to its broad scope and wide applicability, the model can be used by practitioners and researchers alike. As a decision-support system, the model allows users to simulate negotiation situations and estimate the likelihood of negotiation outcomes. As a research platform, it can generate simulation data in a cost- and time-effective way, allowing researchers to simulate complex, large-N studies at no cost or time.

The model presented in this paper synthesizes in a novel way a comprehensive range of concepts and theories of current negotiation research. It complements other computational models, in that it can simulate a more diverse range of negotiation strategies (distributive, integrative and compromise) and is applicable to a greater variety of negotiation scenarios.

The paper seeks to develop an original monetary model for evaluating employees of a company. Employees are an important element of the business process. However, apart from their role as a means of production, their value is not disclosed on the assets side of the classical balance‐sheet. Employees may be disclosed among the assets only if they are expressed in value terms. Therefore, the fundamental aim of the paper is to provide an appropriate monetary mode for valuating employees.

A descriptive approach is sued to identify the basic problems of existing monetary models for valuating employees. According to these findings a totally different approach is taken and an original dynamic model is developed to evaluate employees.

Existing criteria do not offer appropriate solutions for expressing the value of an employee in monetary terms. The model presented here efficiently overcomes most of the practical problems and can be used as an appropriate estimator of employees' value expressed in monetary terms.

The model presented has not been sufficiently verified in practice. The model could prove to be directly applicable in those enterprises that would like to define the value of their employees.

The model presented is original and presents one possible approach to the solution of the problems mentioned above.

The purpose of this paper is to develop mathematical relationships to calculate the loop length to knit compact plain knitted fabrics and to validate the model using the fabric parameters of commercial fabrics.

Ellipse defines the shape of the head of a knitted loop and straight lines define the arms of a knitted loop. The mathematical relationships developed relate the yarn count to the loop length of compact knitted fabrics. The experimental data and the data from previous similar research validate the accuracy of the mathematical model.

The model can calculate loop lengths to knit compact plain knitted fabrics in terms of thickness of the yarn and the coefficient defined to express the ratio of minor axis to major axis of the ellipse that defines the shape of the head of the loop. The mathematical model can deliver several loop lengths to produce compact plain knitted fabrics for different values of this coefficient. For commercial fabrics the error of the model was 0.53%.

The present model defines the head of the loop as an ellipse. The uniqueness of the present model is that several ellipses can exist for any given yarn thickness for a range of values assigned to the minor axis of the ellipse. The accuracy of the model against experimental data ascertains that the model is closer to the reality for commercial fabrics and proves the uniqueness of the model. Further, this model is an ideal and a simple model to introduce knitted loop configurations in teaching knitted fabric geometry.

Several tests have been conducted to determine which valuation model best fits stock price data. Given very little success, those studies suggest the need for a clear understanding of the market process of stock price determination. This paper advances the concepts of product costing and product pricing, which pertain to financial accounting valuation and the stock market price determination, respectively. This research effort presents a workable hypothesis of stock price determination.

The traditional one-stage constant growth formula has two main underlying assumptions: a company will be able to maintain its competitive advantage for completed investments in perpetuity, and each year in the future, it will be able to generate new investment opportunities with the same competitive advantage, which will also remain in perpetuity. The purpose of this paper is to develop a model that limits the duration of the competitive advantage.

A new model is developed, and it is used to value a public company.

In this study, the author introduces an alternative formula considering the duration of the competitive advantage, imposing a restriction on the fact that extraordinary returns cannot be sustained forever, and also separates the part of the value explained by the current investments from the portion of value created by future investments.

The traditional one-stage constant growth model used to determine the continuing value of a company has limitations regarding the duration of the competitive advantage. The developed formula corrects the problem limiting the time extraordinary returns will remain over time.

The paper aims to generate estimates of appraised value using two present value appraisal models. Financing for a commercial property is contingent on an appraiser estimate of value. The paper seeks to address the issue of which approach generally provides more conservative estimates‐of‐value.

The Comparative‐Income Growth Model and Mortgage‐Equity Capitalization models are presented and discussed. Estimates of return to equity while holding the lending rate constant are calculated. This analysis is followed by a mathematical side‐by‐side comparison of the value estimated generated by the respective models.

Depending on the discount rate selected using a fixed lending rate the models yielded comparatively higher, the same or lower estimates of value for a hypothetical commercial property. The mortgage‐equity capitalization model yielded significantly high estimates of value at lower discount rates, but at higher discount rates, the comparative‐income approach estimates were comparatively higher.

A systematic comparison of the appraised values yielded by these two income models has not previously been undertaken in research literature. Explicitly indicating the underlying‐return on equity assumptions for given discount rate has not previously been shown.
