The Role of Client-internal Social Linkages for Outsourcing Success – An SNA Approach

What is the role of a firm’s internal social relations between business departments and IT unit for the success of its IT outsourcing relationship? In this paper, we propose that the relationship between business and IT of a firm is crucial for achieving effective outsourcing management and for enabling the vendor to deliver the services as demanded. Since the business side of the client firm represents the users of the information systems but the IT unit represents the interface to the outsourcing vendor firm, interaction between both units is proposed to be required for maintaining a good outsourcing relationship. Based on a survey in the German Banking Industry and by adopting a Social Network Analysis Approach which captures the interaction structure within the client firm and thus represents an innovative scale to outsourcing research, we show that tight social linkages within the client firm lead to higher service quality achieved by the vendor firm

The Role of Goal Structure in Undergraduates' Use of Self-Regulatory Variables in Two Hypermedia Learning Tasks

Think-aloud and posttest data was collected from 64 undergraduates to examine whether they use a different proportion of self-regulated learning (SRL) variables in two related learning tasks about science topics while using a hypermedia environment. We also manipulated the goal structure of the two learning tasks in order to explore whether goal structure of a learning task is related to the use of SRL variables. Participants were randomly assigned to 1 of 3 conditions [mastery goal structure, performance-approach goal structure, or performance-avoidance goal structure] and participated in two 20 minute learning tasks in which they learned about the circulatory and respiratory system. Results indicate that while a mastery goal structure and a performance-approach goal structure are related to undergraduates' use of a similar proportion of SRL variables in two related learning tasks, a performance-avoidance goal structure is related to undergraduate's use of a different proportion of SRL variables, specifically planning

Learning with hypermedia: Examining cognitive, motivational, and contextual factors

Think-aloud, pretest, posttest, and self-efficacy data collected from 85 undergraduates were used to examine factors related to learning with hypermedia. Participants, randomly assigned to either the No Scaffolding (NS) condition or Conceptual Scaffolding (CS) condition, were given 30 minutes to learn about the circulatory system with hypermedia. Participants in the NS condition received an overall learning goal during the hypermedia learning task, while participants in the CS condition received five guiding questions in addition to the same overall learning goal during the hypermedia learning task. There are four findings from this study. First, results from the pretest and posttest indicated that prior domain knowledge significantly predicted both declarative and conceptual knowledge learning outcomes with hypermedia. Second, results from the self-report self-efficacy questionnaire indicated that while self-efficacy significantly fluctuated during learning, the provision of conceptual scaffolds was not related to this fluctuation. Third, results from a think-aloud protocol indicated that self-efficacy significantly predicted monitoring and planning processes, but not strategy use during the hypermedia learning task. Fourth, results from a think-aloud protocol also indicated that self-regulatory processes (particularly processes related to monitoring) significantly predicted conceptual and declarative learning outcomes. Educational and scientific implications are discussed

KNOWLEDGE MANAGEMENT SYSTEMS, ABSORPTIVE CAPACITY, AND INNOVATION SUCCESS

Innovation is considered a major driving force for the prosperity of firms and entire economies. Research suggests that a firm’s capacity to acquire and utilize relevant knowledge from internal and external sources, i.e. its absorptive capacity (ACAP), is decisive for innovation success. But what is the role of Knowledge Management Systems (KMS) for a firm’s ACAP and innovativeness? Surprisingly, despite lots of mature research on both, ACAP and KMS, there is a gap linking the two. This paper hence asks: What is the effect of knowledge management systems usage on absorptive capacity and innovation success? Responding to recent findings in the management and organizational sciences we develop a theoretical model that links the availability and usage of KMS with a firm’s ACAP and its organizational knowledge to explain innovation success. An empirical evaluation using data from 224 manufacturing firms shows that a firm’s KMS strongly contributes to its ACAP and catalyzes the innovation process. The results suggest that organizational knowledge is important for innovation success and that successful KMS work through enhancing particular facets of ACAP

Revealing the Deposition Mechanism of the Powder Aerosol Deposition Method Using Ceramic Oxide Core–Shell Particles

The powder aerosol deposition (PAD) method is a process to manufacture ceramic films completely at room temperature. Since the first reports by Akedo in the late 1990s, much research has been conducted to reveal the exact mechanism of the deposition process. However, it is still not fully understood. This work tackles this challenge using core–shell particles. Two coated oxides, Al2O3 core with a SiO2 shell and LiNi0.6Mn0.2Co0.2O2 core with a LiNbO3 shell, are investigated. Initially, the element ratios Al:Si and Ni:Nb of the powder are determined by energy-dispersive X-ray spectroscopy (EDX). In a second step, the change in the element ratios of Al:Si and Ni:Nb after deposition is investigated. The element ratios from powder to film strongly shift toward the shell elements, indicating that the particles fracture and only the outer parts of the particles are deposited. In the last step, this work investigates cross-sections of the deposited films with scanning transmission electron microscopy (STEM combined with EDX and an energy-selective back-scattered electron (EsB) detector to unveil the element distribution within the film itself. Therefore, the following overall picture emerges: particles impact on the substrate or on previously deposited particle, fracture, and only a small part of the impacting particles that originate from the outer part of the impacting particle gets deposited

A simple biodiversity assessment scheme supporting nature-friendly farm management

Farmers are important actors for regional development and biodiversity protection. Agri-environment-climate measures (AECM) are therefore a central tool of the European Union to support its biodiversity conservation policy. AECM generally reward farmers for fulfilling predefined management actions or avoiding specific practices. In contrast, result oriented AECM are intended to reward farmers for the outcome of nature friendly management practices. This approach gives more flexibility in management and hence promotes farmers engagement and autonomy. Besides educational activities and agricultural advisory services farmers need user friendly tools to assess biodiversity in order to meet result oriented AECM. Thus, we present a biodiversity assessment scheme for farmland using a set of indicators, which covers different aspects of biodiversity (flower colour index, butterfly abundance, landscape structuring degree, patch diversity index, aggregated biodiversity index) and can be applied at different spatial scales. The assessment scheme is applied on 44 farms in five countries (France, Switzerland, Germany, Italy, and Austria). To evaluate its appropriateness the relationship between the indicators and land-use intensity and plant species richness is investigated. Grasslands with low land-use intensity are more colourful grasslands, have significantly more butterflies and a higher aggregated biodiversity index than moderately and intensively used grasslands. The influence of management intensity on the landscape structuring degree is not significant. All indicators correlate with plant species richness at all spatial scales. The proposed assessment scheme serves as a tool for the detection of differences in biodiversity resulting from land-use practices, and can assist the monitoring of ROMs

The colonic mucosa-associated microbiome in SIV infection: shift towards Bacteroidetes coincides with mucosal CD4(+) T cell depletion and enterocyte damage

Allers K, Stahl-Hennig C, Fiedler T, et al. The colonic mucosa-associated microbiome in SIV infection: shift towards Bacteroidetes coincides with mucosal CD4(+) T cell depletion and enterocyte damage. SCIENTIFIC REPORTS. 2020;10(1).The intesinal microbiome is considered important in human immunodeficiency virus (HIV) pathogenesis and therefore represents a potential therapeutic target to improve the patients' health status. Longitudinal alterations in the colonic mucosa-associated microbiome during simian immunodeficiency virus (SIV) infection were investigated using a 16S rRNA amplicon approach on the Illumina sequencing platform and bioinformatics analyses. Following SIV infection of six animals, no alterations in microbial composition were observed before the viral load peaked in the colon. At the time of acute mucosal SIV replication, the phylum Bacteroidetes including the Bacteroidia class as well as the phylum Firmicutes and its families Ruminococcaceae and Eubacteriaceae became more abundant. Enrichment of Bacteroidetes was maintained until the chronic phase of SIV infection. The shift towards Bacteroidetes in the mucosa-associated microbiome was associated with the extent of SIV infection-induced mucosal CD4(+) T cell depletion and correlated with increasing rates of enterocyte damage. These observations suggest that Bacteroidetes strains increase during virus-induced mucosal immune destruction. As Bacteroidetes belong to the lipopolysaccharide- and short chain fatty acids-producing bacteria, their rapid enrichment may contribute to inflammatory tissue damage and metabolic alterations in SIV/HIV infection. These aspects should be considered in future studies on therapeutic interventions
