Purpose
Supply chain relationships have often been analysed from the macro-perspective of the companies involved, but there is less evidence of how relationships relate to the micro-perspective of persons involved. The purpose of this paper is to investigate, in IT outsourcing (ITO), how the buyer–supplier relationship type strengthens buyer performance from the perspective of consultants.
Design/methodology/approach
IT consultants were surveyed, and analysis was performed considering the aggregated values of variables that characterise buyer–supplier relationships adjusted to ITO.
Findings
The results show that strategic relationships are associated with higher supplier investment in relational management than in transactional ones. Similarly, in this type of relationship, higher levels of trust are linked to the recognition of more activities shared between parties involved than in transactional relationships. The improvement of supplier development by buyers was also found to improve buyers’ performance.
Research limitations/implications
The model proposed here was developed for nonspecific industries but tested in the context of ITO. Further research should be undertaken to broaden generalisability.
Originality/value
The paper provides an understanding of the influence of the buyer–supplier relationship type on buyer performance based both on relational management and, more specifically, how the formal dimension of supplier development can also contribute to performance. ITO is increasing worldwide, and relational management affects outsourcing outcomes in broad supply chain integration. This analysis is usually visited from buyer and supplier perspectives using decision makers. This paper assesses it from the perspective of consultants.
The present work aimed to evaluate the healing effect of hydrophilic polymeric resorbable biomembrane scaffolds containing plant extracts obtained from two different species, both popularly known as Stryphnodendron adstringens or Barbatimão. The hydrogel-based scaffolds were characterized and submitted to biological tests using Wistar rats to evaluate their healing capacity. The wound retraction index and the evaluation of the inflammatory process and tissue collagenization were recorded. The extracts showed antioxidant activity with IC50 between 10 and 20 µg/mL (DPPH assay) and 4–6 mmol Trolox/g (FRAP assay). The extract of Stryphnodendron adstringens (SA) presented gallocatechin, epigallocatechin, and O-methylpigalocatechin, while the extract of Abarema cochliacarpa (AC) presented catechin, dimers of procyanidins, di-O-hydroxide, O-deoxyhexosi-hexoside, and epicatechin. The membranes containing SA extract (GELSA) were more rigid, with a more intense color, but less thick, with a more compact structure and few pores. The membranes containing AC extract (GELAC) presented a mechanical profile like the gelatin membrane (GEL), with greater permeability to water vapor. The GELAC and GELSA membranes showed similar thermal degradation profiles. The wounds treated with the membranes containing the extracts obtained high levels of retraction of the wounds with values around 60% and 80% in three and seven days, respectively. These data indicate that the compounds of both species have promising biological activities in the repair process, showing that the extracts accelerated the healing process due to the lower intensity of the inflammatory reaction and the presence of compounds such as catechin and epigallocatechin.
This paper presents the Learning Scorecard (LS), a platform that enables students to monitor their learning progress in a Higher Education course during the semester, generating the data that will also support the ongoing supervision of the class performance by the course coordinator. The LS uses gamification techniques to increase student engagement with the course. Business Intelligence best practices are also applied to provide an analytical environment for student and faculty to monitor course performance. This paper describes the initial design of the LS, based on a Balanced Scorecard approach, and the prototype version of the platform, currently in use by graduate and undergraduate students in the fall semester of 2016-2017.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
