Tetrapeptide analogue H-[Glu-Ser-Lys(Thz)]-OH, containing a turn-inducing thiazole constraint, was used as a template to produce a 21-membered structurally characterized loop by linking Glu and Lys side chains with a Val-Ile dipeptide. This template was oligomerized in one pot to a library (cyclo-[1](n), n = 2-10) of giant symmetrical macrocycles (up to 120-membered rings), fused to 2-10 appended loops that were carried intact through multiple oligomerization (chain extension) and cyclization (chain terminating) reactions of the template. A three-dimensional solution structure for cyclo-[1](3) shows all three appended loops projecting from the same face of the macrocycle. This is a promising approach to separating pepticle motifs over large distances.

SMEs with a weak internal R&D capacity show the tendency to shy away from using external sources of technical expertise. The tendency deters providers of industrial modernization services from supporting such structurally weak SMEs. This paper examines how Japan's local technology centres - kosetsushi - remove the bottleneck and reach out to a significant proportion of SMEs with a weak R&D capacity in their localities. Kosetsushi centres sustain habitual interactions with client firms through 'low information gap' services solving immediate needs and lead the clients to a riskier and longer path toward innovation capacity building. This gives kosetsushi centres a position distinct from universities and consultancies in the regional innovation system. While long-term relationships between kosetsushi centres and their client firms can increase switching costs and produce lock-in effects, a case study of two kosetsushi centres illustrates the importance of 'low-information gap' services and relational assets created thereby to the modernization of SMEs with a weak internal R&D capacity. The paper calls for long-term commitment by the public sector if it addresses the issue through modernization services.

This paper has two objectives: first, to provide a brief review of developments in the sociology of scientific knowledge (SSK); second to apply an aspect of SSK theorising which is concerned with the construction of scientific knowledge. The paper offers a review of the streams of thought which can be identified within SSK and then proceeds to illustrate the theoretic constructs introduced in the earlier discussion by analysing a particular contribution to the literature on research methodology in accounting and organisations studies. The paper chosen for analysis is titled “Middle Range Thinking”. The objective of this paper is not to argue that the approach used in this paper is invalid, but to seek to expose the rhetorical nature of the argumentation which is used by the author of the paper.

Journal rankings are frequently used as a measure of both journal and author research quality. Nonetheless, debates frequently arise because journal rankings do not take into account the underlying diversity of the finance research community. This study examines how factors such as a researcher's geographic origin, research interests, seniority, and journal affiliation influence journal quality perceptions and readership patterns. Based on a worldwide sample of 862 finance academics, we find remarkable consistency in the rankings of top journals. For the remaining journals, perception of journal quality differs depending on the researcher's geographic origin, research interests, seniority, and journal affiliation.

The practice of evaluating faculty and business schools based on their journal publications has increased the emphasis on research output in peer reviewed journals. Since journal standings are a frequently debated issue, this study seeks to examine the perceptual differences of journals between different segments of marketing academics. Based on a worldwide online survey, journals are assessed in terms of four subjective quality metrics: journal familiarity, average rank position, percent of respondents who classify a journal as top tier, and readership. It is demonstrated that an individual's geographic origin, research interests or journal affiliation can have a significant impact on journal rankings.
