Two different theoretical frameworks, the interorganizational and the intraclass, guide empirical research on the origin and function of corporate interlocks. Conclusions from this research often have been used as the basis for more general claims about the structure of power in the American economy. To a great extent, these claims are based on the implicit assumption that a majority of interlocks facilitate one type of interfirm relationship—formal coordination.This article presents evidence about the continuity of interlocks which have been disrupted accidentally by such events as death and retirement. What happens after an interlock is broken reveals something of the extent and manner in which different types of interlock ties facilitate formal coordination. This in turn provides the basis for assessing the applicability of the interorganizational and intraclass approaches to the phenomenon of interlocking.

Melting And Solidification

The representation of the properties and phenomena of the physical world exists from the beginning of life, as a first datum of reality. In several studies focused on children's representations we find that these representations these representations are critical to education and are often incompatible with the scientific model. This article presents the results of an empirical research on the representations of young children for melting and solidification of salt. The research sample consisted of 79 pre-school children (five to six years old) from one state kindergarten in Greece. Data were collected through expanded, open type, semi-structured individual conversations between a child of the sample and one researcher. The results of the interviews show that these children use different types of representations, the majority dominated by the nature of the substance under study.

Abstract In real-world networks, there usually exist a small set of nodes that play an important role in the structure and function of networks. Those vital nodes can influence most other nodes in the network via a spreading process. While most of the existing works focused on vital nodes that can maximize the spreading size in the final stage, which we call final influencers, recent work proposed the idea of fast influencers, which emphasizes nodes’ spreading capacity at the early stage. Despite the recent surge of efforts in identifying these two types of influencers in networks, there remained limited research on untangling the differences between fast influencers and final influencers. In this paper, we first distinguish the two types of influencers: fast-only influencers and final-only influencers. The former is defined as individuals who can achieve a high spreading effect at the early stage but lose their superiority in the final stage, and the latter are those individuals that fail to exhibit a prominent spreading performance at the early stage but influence a large fraction of nodes at the final stage. Further experiments based on eight empirical datasets, we reveal the key differences between the two types of influencers concerning their spreading capacity and the local structures. We also analyze how network degree assortativity influences the fraction of the proposed two types of influencers. The results demonstrate that with the increase of degree assortativity, the fraction of the fast-only influencers decreases, which indicates that more fast influencers tend to keep their superiority at the final stage. Our study provides insights into the differences and evolution of different types of influencers and has important implications for various empirical applications, such as advertisement marketing, and epidemic suppressing.

Purpose The main goal of the paper is to describe the knowledge interconnection process embedded in an interactive business relationship. The purpose of this study is to understand the knowledge interconnection inside the supplier-buyer relationship in the field of contract manufacturing. The knowledge interconnection process is defined by the authors as a process linked to business relationships, which contains different types of knowledge and various sub-processes related to them. Design/methodology/approach The Industrial Marketing and Purchasing Group (IMP) research framework has been applied and the contribution is a better understanding of the role of knowledge in the interactive business world. The empirical evidence is based on a case study of a Hungarian contract manufacturing company. This paper describes empirical, qualitative research about knowledge interconnection processes applying an abductive research design. Findings The knowledge interconnection process is linked to business relationships. It is a complex process, which contains three types of knowledge and five sub-processes. The knowledge evolution indicates the links between the different types of knowledge. The sub-processes relate to different types of knowledge and allow the flow of knowledge between the supplier and the buyer. In the business relationship, this flow of knowledge makes possible the new knowledge creation. A model of the knowledge interconnection process has been developed. Research limitations/implications Single case studies can create rich descriptions of complex phenomena, but the possibility for generalization is limited. Another limitation is that the knowledge interconnection process has been studied only from the supplier’s perspective. The present research extends IMP’s knowledge of embedded knowledge. In addition, empirical research contributes to the emerging field of IMP research that explores knowledge as a resource but lacks an empirical foundation. Practical implications The knowledge interconnection process is a decisive factor in the development and maintenance of long-term customer relations in the field of contract manufacturing. The evolution of knowledge types – from the body of knowledge to knowledge in use – demands the management of different sub-processes. Knowledge selection, knowledge recombination, knowledge mobilization and new knowledge creation processes are more strongly related to the supplier-customer dyad, while the knowledge relocation process has a network character. The knowledge interconnection process influences the company’s body of knowledge and its relationship management capability. Originality/value The originality of the study is, on the one hand, an empirical examination of the process of knowledge interconnection. On the other hand, the development of a model of the knowledge interconnection process. A further feature is that empirical research has been conducted in the field of contract manufacturing.

With very few exceptions, the basic structure of the 9+2 axoneme has been well preserved over a very long period of evolution from protozoa to mammais. This stability indicates that the basic structural components of the axoneme visible by electron microscopy, as well as most of the other unidentified components, have withstood the passage of time. It also means that components of the 9+2 axoneme have sufficient diversity in function to accommodate the various types of motility patterns encountered in different species of flagella. Several of the 200 polypeptides that constitute the axoneme have been identified as components of the dynein arms, radial spokes etc. but many more remain to be identified and their function(s) remain to be determined. Because this review deals with the regulation of flagellar movement at the axonemal level, it does not include regulation of flagella by extracellular factors unless these factors have a direct action on axonemal components. In this context, it is very important firstly to understand the structural components of the axoneme and how they influence and regulate axonemal movement. Different primitive organisms are mentioned in this review since major breakthroughs in our understanding of how an axoneme generates different types of movement have been made through their study. Despite some variations in structure and function of axonemal components, the basic mechanisms involved in the regulation of flagella from Chlamydomonas or sea urchin spermatozoa should also apply to the more evolved mammalian species, including human spermatozoa.

Collagen is the core protein of connective tissues: skin, bone, tendon, base membrane, etc. Collagen is actually a family of several different genetic types. Currently they are known, in vertebrates, at least 27 different types of collagens, which shows a remarkable diversity in molecular and supramolecular organization of the tissue distribution and function, discovered and developed over 45 years. They were studied, in detail, 12 main types. Collagen-based bioproducts can be produced in a variety of molecular structures (micro and nano structures) in powder form, hydrogels and injectable solutions, films, membranes and matrices, etc. This paper presents the drying processes that are selected depending on the nature of the extract (undenatured or denatured) and morphological structure bioproduct or sponge, fibers or membranes. The most frequently used procedures for drying are freeze-drying and free drying at a temperature of approx. 25 ° C. Both processes produce no distorts to the extracts They are presented bioproducts derived from collagen which are used in medicine.
