Abstract
In this introduction, the authors outline some critical reflections on the sociology of knowledge within management and organization theory. Based on a review of various works that form a sociology of organizational knowledge, the authors identify three approaches that have become particularly prominent ways by which scholars explore how knowledge about organizations and management is produced: First, reflective and opinion essays that organization studies scholars offer on the basis of what can be learned from personal experience; second, descriptive craft-guides that are based on more-or-less comprehensive surveys on doing research; third, papers based on systematic research that are built upon rigorous collection and analysis of data about the production of knowledge. Whereas in the studies of organizing the authors prioritize the third approach, that is knowledge produced based on systematic empirical research, in examining our own work the authors tend to privilege the other two types, reflective articles and surveys. In what follows the authors highlight this gap, offer some explanations thereof, and call for a better appreciation of all three ways to offer rich understandings of organizations, work and management as well as a fruitful sociology of knowledge in our field.

Abstract
The circumstances for the emergence of new ideas in organizational theory have previously been explored from several viewpoints. Researchers trace the origins of new ideas to previous literature or compare ideas across continents and countries. The author takes another point of departure. Following Merton (1957, 1963), she focuses on “multiple discoveries” in science, studying the independent, simultaneous (re-)discovery of certain aspects of institutional theory in organizational theory. Specifically, she follows the circumstances under which two pairs of researchers proffered similar explanations for the phenomena they encountered (Jönsson & Lundin, 1977; Meyer & Rowan, 1977). Without ever having met, they suggested an analogous way of understanding the concept of organizing, though their research used different frames of reference and field material and was published in different outlets. The author’s analysis of the circumstances surrounding the two papers led her to explore elements in the emergence of new ideas: the Zeitgeist – the spirit of the times – international networks, and collegial work. When these factors are in play, physical meetings do not seem to be required, but scholars must be involved in networks in which their colleagues provide judgment and advice.

Abstract
Purpose
Goat milk yoghurt differs from cow milk yoghurt in that it has a different casein composition and content, which presents several technical challenges, including consistency with an appropriate flavor.
Design/methodology/approach
In this study, the antioxidant potential and phytochemical profiling of the fruits (pineapple and papaya) and vegetable (carrot) extracts was evaluated and the effect of their purees on the quality and stability of stirred goat milk yoghurt (GMY) were investigated. The qualities of stirred GMY with carrot (CrY), pineapple (PaY) and papaya (PpY) purees were assessed against the product without puree (CY).
Findings
The carrot puree had the highest moisture, ash contents and pH value. The carrot extract had the highest DPPH radical scavenging activity, while the pineapple extract had the highest total phenolic value (1.59 µg GAE/g) and flavonoids content (0.203 µg CE/g). The scanning of all the puree extracts in GC-MS indicated that 5-hydroxymethylfurfural was a major component. The phytochemical quantification of the extracts through multiple reaction monitoring (MRM) against 16 compounds showed the presence of sinapic acid, cinnamic acid, pthalic acid, ferulic acid, 4-OH-benzoic acid, 3-OH-benzoic acid, p-coumaric acid, caffeic acid and vanillic acid in different quantities. The addition of purees and storage period had a significant (p < 0.05) effect on the moisture, pH, titratable acidity, syneresis, viscosity, color values and sensory properties of the products. In all the samples after 15 days of storage, Streptococcus thermophilus and Lactobacillus bulgaricus counts remained above the recommended level of 106CFU/g. Stirred GMY sample produced with pineapple puree showed a higher syneresis and viscosity, but the CrY sample demonstrated the highest antioxidant activity. The developed formulations remained stable with minimum changes in quality and sensory attribute during refrigerated storage for 10 days.
Originality/value
This study suggests that addition of fruit and vegetable improve the viscosity and sensory perception of the product with minimal use of synthetic flavor and preservatives.

Abstract
This study sought to assess perceptions of support for organizational change and model the relationship between support for organizational change and leadership competencies among Extension educators. The knowledge gained through this work should expand current understandings regarding the nature, scope, and value of support for organizational change within the Extension educator role. We found that Extension educators mostly support organizational change. Our study also showed that leadership competencies predict a significant proportion of the total variation in overall support for organizational change. Extension leaders and leadership development practitioners should be aware that leadership education may increase receptivity to organizational change among educators.

Abstract
Purpose
Grape juice concentrate (GJC) composition is affected by different factors including grape type and production conditions. So this study aimed to determine composition and nutrition value of GJC in eight cities in Khorasan province in north east of Iran in order to use the data in nutrition value tables.
Design/methodology/approach
The GJC samples (20) were supplied from local supermarkets in nine cities in Khorasan province in Iran. Total and soluble dry matter, total sugar, protein, fat, soluble fiber, ash and pH were determined according to standard methods. Nutritious minerals including calcium, phosphorus, magnesium and iron were detected using atomic absorption spectroscopy method.
Findings
The chemical properties of GJC samples were determined as follows: total dry matter 73.66 percent; protein 1.46 percent, total sugar 68.03 percent; soluble fiber 2.69 percent, ash 0.71 percent and fat 1.08 percent. The average values of pH and brix were, respectively, 4.25 and 65.5°. The mineral content was found as follows: calcium 817 ppm; sodium 0.9 percent; phosphorus 492 ppm; magnesium 1,704 ppm and iron 60 ppm.
Originality/value
The composition and nutritional value of GJC in Iran had not been determined before. The findings on nutritive properties of GJC can be used in nutrition value tables.

Abstract
In this chapter, the author outlines the link between organization design and competitive strategy, focusing on rivalry. A firm’s organization design choices can affect its competitive advantage as well as the strategic decisions of its rivals. Therefore, organization design can influence the nature and intensity of competitive interactions between firms. To illustrate this effect, the author focuses on the literature on divisionalization and offers a set of propositions as examples. Taken together, the author makes three main observations: (1) a firm’s competitive position and objectives are reflected in its organizational choices; (2) heterogeneity in competitive position and objectives lead to heterogeneity in organization design choices across firms; and (3) organization design and competitive strategy are interdependent processes. The author concludes by discussing the implications for strategy and management research and pointing out some opportunities for future research.

Abstract
Purpose
In the literature, while designing broadband matching networks, transducer power gain (TPG) is used to measure the transferred power. Generally, in TPG expressions, load and back-end impedances of the matching network are used. This study aims to derive a new quality factor-based TPG expression.
Design/methodology/approach
In deriving the new expression, narrowband L type-matching network design approach is used and the new expression in terms of back-end quality factor, load quality factor and output port quality factor is obtained. Then, a broadband-matching network design approach using the derived TPG expression is proposed.
Findings
Two broadband double-matching networks are designed by using the proposed design approach using the derived TPG expression. Performances of the designed-matching networks are compared with the performances of the matching networks designed by means of simplified real frequency technique which is a well-known technique in the literature, and it is shown that they are nearly the same.
Originality/value
In broadband-matching problems, generally an impedance-based TPG expression is used, and it must be satisfied by the designed broadband-matching networks. But, in the literature, there is no quality factor-based TPG expression that can be used in broadband-matching problems. So, this gap in the literature has been filled by this paper.
