EXPANDING THE BOUNDARY OF BRAND EXTENSIONS THROUGH BRAND RELATIONSHIP QUALITY
Research on brand extensions identifies the concept of perceived fit as the prime determinant of success. Yet, it is not difficult to find examples of brands that have been extended successfully into "perceptually distant" domains. In an attempt to resolve this discrepancy between research insights and practical experiences, the study investigates the role of Brand Relationship Quality (BRQ) as a critical factor determining consumer responses to brand extensions. The proposed model is tested separately in the context of three different fit scenarios (high, moderate, and low) with data from 502 consumers. The results indicate that BRQ and perceived fit exert independent effects on consumer responses and complement each other as they jointly influence evaluations of brand extensions. The study therefore extends existing theory by providing evidence that the brand extension phenomenon cannot be explained justly without including constructs that portray personal relationships consumers develop with brands and provides insights for marketers and researchers as to how such relationships can be integrated in formulations of successful brand extension strategies
Microbial composition of Kombucha determined using amplicon sequencing and shotgun metagenomics
Kombucha, a fermented tea generated from the co-culture of yeasts and bacteria, has gained worldwide popularity in recent years due to its potential benefits to human health. As a result, many studies have attempted to characterize both its biochemical properties and microbial composition. Here, we have applied a combination of whole metagenome sequencing (WMS) and amplicon (16S rRNA and Internal Transcribed Spacer 1 [ITS1]) sequencing to investigate the microbial communities of homemade Kombucha fermentations from day 3 to day 15. We identified the dominant bacterial genus as Komagataeibacter and dominant fungal genus as Zygosaccharomyces in all samples at all time points. Furthermore, we recovered three near complete Komagataeibacter genomes and one Zygosaccharomyces bailii genome and then predicted their functional properties. Also, we determined the broad taxonomic and functional profile of plasmids found within the Kombucha microbial communities. Overall, this study provides a detailed description of the taxonomic and functional systems of the Kombucha microbial community. Based on this, we conject that the functional complementarity enables metabolic cross talks between Komagataeibacter species and Z. bailii, which helps establish the sustained a relatively low diversity ecosystem in Kombucha
Performance implications of institutionalization process in family-owned businesses: Evidence from an emerging economy
This paper attempts to understand the role of two highly relevant founder family characteristics, harmony among family members and the degree of democratization in decision-making, in the institutionalization and adaptive capability development processes of family firms in Turkey as an exemplar of an emerging market. The paper examines how institutionalization and adaptability jointly drive firm-level differences in quantitative (i.e., sales growth, market share, and return on investment) and qualitative performance (i.e., quality of goods/services, new product development, employee satisfaction) components. Data were collected from 436 respondents in 132 family firms through structured questionnaires administered to at least three respondents from each firm. Findings indicated that among the institutionalization dimensions, transparency had the strongest effect on both quantitative and qualitative firm performance, whereas adaptability influenced qualitative performance only. Harmony in family relations increased efforts for institutionalization, whereas democracy in decision-making enhanced adaptability. Implications of these findings are discussed and several future research directions are suggested.Organizational institutionalization Family firms Organizational adaptability Organizational performance Emerging markets
Whole mitochondrial genome analysis of a family with NARP/MILS caused by m.8993T > C mutation in the MT-ATP6 gene
Mutations in mitochondrial DNA (mtDNA) encoded nucleotide 8993 can cause NARP syndrome (neuropathy, ataxia, and retinitis pigmentosa) or MILS (maternally inherited Leigh syndrome). The rare T8993C mutation in the MT-ATP6 gene is generally considered to be clinically milder, but there is marked clinical heterogeneity ranging from asymptomatic carriers to fatal infantile Leigh syndrome. Clinical heterogeneity has mostly been attributed to mtDNA heteroplasmy, but environmental, autosomal, tissue-specific factors, nuclear modifier genes, and mtDNA variations may also modulate disease expression. Here, we report the results of whole mitochondrial genome analysis of a family with m.8993T>C mutation in the MT-ATP6 gene and associated with NARP/MILS, and discuss the familial inheritance, effects of variation in combinations and heteroplasmy levels on the clinical findings. The whole mitochondrial genome was sequenced with similar to 182x average depth of coverage per sample with next-generation sequencing technology. Thus, all heteroplasmic (>%10) and homoplasmic variations were determined (except for 727C insertion) and classified according to the associations with mitochondrial diseases. (C) 2012 Elsevier Inc.

Genomic analysis reveals the biotechnological and industrial potential of levan producing halophilic extremophile, Halomonas smyrnensis AAD6T
Halomonas smyrnensis AAD6T is a gram negative, aerobic, and moderately halophilic bacterium, and is known to produce high levels of levan with many potential uses in foods, feeds, cosmetics, pharmaceutical and chemical industries due to its outstanding properties. Here, the whole-genome analysis was performed to gain more insight about the biological mechanisms, and the whole-genome organization of the bacterium. Industrially crucial genes, including the levansucrase, were detected and the genome-scale metabolic model of H. smyrnensis AAD6T was reconstructed. The bacterium was found to have many potential applications in biotechnology not only being a levan producer, but also because of its capacity to produce Pel exopolysaccharide, polyhydroxyalkanoates, and osmoprotectants. The genomic information presented here will not only provide additional information to enhance our understanding of the genetic and metabolic network of halophilic bacteria, but also accelerate the research on systematical design of engineering strategies for biotechnology applications
Mitochondrial DNA profiling via genomic analysis in mesial temporal lobe epilepsy patients with hippocampal sclerosis
Introduction: Mitochondria have an essential role in neuronal excitability and neuronal survival. In addition to energy production, mitochondria also play a crucial role in the maintenance of intracellular calcium homeostasis, generation of reactive oxygen species and mechanisms of cell death. There is a relative paucity of data about the role of mitochondria in epilepsy. Mitochondrial genome analysis is rarely carried out in the investigation of some diseases. In mesial temporal lobe epilepsies (MTLE) cases, genome analysis has never been used previously. The aim of this study is to show mitochondrial dysfunctions using genome analysis in patients with MTLE-hippocampal sclerosis (HS)
