A Business Intelligence Model for SMEs Based on Tacit Knowledge

This paper proposes a specific model of business intelligence in relation with SMEs practices, culture and competitive environment. This model is based on the mobilization of corporate tacit knowledge and informal information, aiming at interpreting anticipatory environmental information and assist strategic decision making. An empirical survey assessing the existing business intelligence practices in 20 French SMEs has identified seven necessary acceptance conditions of a business intelligence project as well as a managerial tool allowing tacit knowledge traceability.business intelligence; tacit knowledge; SMEs; sense-making

Chore division on a graph

The paper considers fair allocation of indivisible nondisposable items that generate disutility (chores). We assume that these items are placed in the vertices of a graph and each agent's share has to form a connected subgraph of this graph. Although a similar model has been investigated before for goods, we show that the goods and chores settings are inherently different. In particular, it is impossible to derive the solution of the chores instance from the solution of its naturally associated fair division instance. We consider three common fair division solution concepts, namely proportionality, envy-freeness and equitability, and two individual disutility aggregation functions: additive and maximum based. We show that deciding the existence of a fair allocation is hard even if the underlying graph is a path or a star. We also present some efficiently solvable special cases for these graph topologies

Requisite variety and intercultural teams: to what extent is Ashby's law useful ?

Requisite variety and intercultural teams: To what extent is Ashby's law useful? The “Law of Requisite Variety” (LRV) is frequently evoked to explain the design, functioning and performance of intercultural teams. But to what extent does the law really enhance understanding in this particular field? The authors consider that LRV has rarely been questioned in-depth in management studies. The paper briefly details LRV in the cybernetics context before “translating” it to social systems, organizations and intercultural teams. Using a qualitative case-study method, the case of an intercultural team is analysed and questioned from the perspective of LRV. The results show that LRV superficially fits the composition of this team, but is unable to explain the human and social dynamics that evolve during the work process.law of requisite variety; requisite variety; intercultural teams ; complexity ; diversity; systems; case study

Community on the watch: making sense of is research through the lens of espoused theories of is

Community on the Watch: Making Sense of IS Research through the Lens of Espoused Theories of IS In the IS field there has been an ongoing tradition to study the publication output of the community in order to evaluate the current and potential situation of IS research. In this work, we follow a different strategy and study what IS research claims to be. We look at those so-called 'espoused theories of IS' as found in the General Editorials Statements (GES) of IS journals. Based on the AISWorld journal ranking, we collected GES for 30 leading IS journals for the years 1997 and 2007. We applied thematic, lexicometric, and factor analyses to the datasets of the 1997 and the 2007 GES. Our results show that the representation of IS research in the GES has changed little over the last decade.: Espoused Theory, Information Systems (IS), Research, Expectations, General Editorial Statement (GES), IS Journals, Thematic Analysis, Lexicometric Analysis.

From genotype to phenotype in human atherosclerosis - recent findings

Purpose of reviewSince 2007, genome-wide association studies (GWAS) have led to the identification of numerous loci of atherosclerotic cardiovascular disease. The majority of these loci harbor genes previously not known to be involved in atherogenesis. In this review, we summarize the recent progress in understanding the pathophysiology of genetic variants in atherosclerosis.Recent findingsFifty-eight loci with P<10(-7) have been identified in GWAS for coronary heart disease and myocardial infarction. Of these, 23 loci (40%) overlap with GWAS loci of classical risk factors such as lipids, blood pressure, and diabetes mellitus, suggesting a potential causal relation. The vast majority of the remaining 35 loci (60%) are at genomic regions where the mechanism in atherogenesis is unclear. Loci most frequently found in independent GWAS were at Chr9p21.3 (ANRIL/CDKN2B-AS1), Chr6p24.1 (PHACTR1), and Chr1p13.3 (CELSR2, PSRC1, MYBPHL, SORT1). Recent work suggests that Chr9p21.3 exerts its effects through epigenetic regulation of target genes, whereas mechanisms at Chr6p24.1 remain obscure, and Chr1p13.3 affects plasma LDL cholesterol.SummaryNovel GWAS loci indicate that our understanding of atherosclerosis is limited and implicate a role of hitherto unknown mechanisms, such as epigenetic gene regulation in atherogenesis
