Improving SMEs competitiveness with the use of Instagram Influencer Advertising and eWOM

Under Saudi Vision 2030, there will be a forthcoming increase in support to small or medium-sized enterprises (SMEs) from the current 20 percent of GDP to 35 percent. Thus, SMEs’ access to finance will become easier. At the same time, the cosmetics retail industry is expected to rapidly grow in the next few years because of the already mounting demand and availability of cosmetics through online channels. The purpose of this study is to explore the use of beauty Instagram influencers in advertising as a tool to increase competitiveness for SMEs. An exploratory research design was employed, and in-depth interviews conducted to gain a better understanding of female Saudi young adults’ perceptions of trust towards Instagram influencers, electronic word-of-mouth (eWOM), and advertising. Implications for SMEs managers are also discussed

Exploring HR practitioners’ perspective on employer branding and its role in organisational attractiveness and talent management

© 2017, © Emerald Publishing Limited. Purpose: The latest research in the field of employer branding highlights a mix of marketing principles and recruitment practices, based on the concept that, just as customers have perceptions of an organisation’s brand, then so do other stakeholders including employees. However, the emphasis has been on organisations, which predominantly operate in developed countries typically with Westernised-individualistic cultures. This paper aims to investigate employer branding for service organisations’ image and attraction as an employer in a non-Western culture. Design/methodology/approach: This study examines the perceptions of human resources’ professionals and practitioners on the role of employer branding in employer attractiveness and talent management, within Mauritian banking sector. The data collection for this qualitative study involved semi-structured interviews with senior managers from Mauritian banking organisations, including multinational enterprises, small business unit banks and Mauritian banks. Findings: Analysis of the findings showed that organisations, and banks in this case, are increasingly competing to attract highly skilled personnel in various professional areas; therefore, those organisations that attract the best talent will have a distinct edge in the marketplace. Furthermore, findings from the semi-structured interviews with senior managers suggest that employer branding remains at the embryonic stage within the Mauritian banking sector; therefore, a clear need exists for a more developed strategy. Research limitations/implications: The outcomes of this study call for re-engineering with regards to managerial collaboration in organisations for the successful design and implementation of the employer branding strategy. The empirical findings from the Mauritian banking sector show that the strategic position occupied by the human resource function is still at an embryonic stage as regards with the competitiveness of banks as service organisations. Practical implications: The study presents a need for the development and maintenance of long-term collaborative and trust-based relationships between the human resource and marketing functions. Originality/value: The insights provided through this study addresses the dearth of academic research on employer branding on the African continent while providing invaluable information from a human resource professional perspective

Do ethical work climates influence supplier selection decisions in public organizations? The moderating roles of party politics and personal values.

Purpose - This study examined the relationship between ethical work climates (EWCs) and supplier selection decisions (SSD), and the moderating roles of party politics and personal values on this relationship. Design/methodology/approach - A total of 600 senior level personnel from 40 Nigerian public organizations were surveyed using structured questionnaires. Multiple regression analysis was used to test the hypotheses developed for the study after assessing construct reliability and validity. Findings - Results show that both high and low levels of external political pressures significantly reduce the perception that organisational SSDs are ruled-based and pro-social in nature. Furthermore, regardless of the level of perception of instrumental personal values by employees, instrumental ethical climates significantly determine SSDs; principled/cosmopolitan climate and benevolent/cosmopolitan climate only become significant perceptible determinants when there is less room for the accommodation of personal goals during SSD processes. Research limitations/implications - This study only examined the relationship between ethical climate perceptions and supplier selection decisions without controlling for the effects of some important possible intervening variables on this relationship. Therefore, the study encouraged future researcher to enhance the generalizability of our findings by incorporate relevant control variables in the model, as well as examining other decision phases in the public buying process. Originality/value – This study is original to the extent that only a few studies in the literature are devoted to perceptions of EWCs in African organizations, and no previous studies have examined this phenomenon in relation to SSDs in Nigerian public firms. Key Words: Ethical Work Climates, Supplier Selection Decisions, Public Sector, Nigeria, Party Politics, and Personal Values

Mutations in NDUFS1 Cause Metabolic Reprogramming and Disruption of the Electron Transfer

Complex I (CI) is the first enzyme of the mitochondrial respiratory chain and couples the electron transfer with proton pumping. Mutations in genes encoding CI subunits can frequently cause inborn metabolic errors. We applied proteome and metabolome profiling of patient-derived cells harboring pathogenic mutations in two distinct CI genes to elucidate underlying pathomechanisms on the molecular level. Our results indicated that the electron transfer within CI was interrupted in both patients by different mechanisms. We showed that the biallelic mutations in NDUFS1 led to a decreased stability of the entire N-module of CI and disrupted the electron transfer between two iron-sulfur clusters. Strikingly interesting and in contrast to the proteome, metabolome profiling illustrated that the pattern of dysregulated metabolites was almost identical in both patients, such as the inhibitory feedback on the TCA cycle and altered glutathione levels, indicative for reactive oxygen species (ROS) stress. Our findings deciphered pathological mechanisms of CI deficiency to better understand inborn metabolic errors

Prevalence of BRCA1 and BRCA2 mutations in unselected breast cancer patients from Greece

<p>Abstract</p> <p>Background</p> <p>Inheritance of a mutation in either <it>BRCA1 </it>or <it>BRCA2 </it>accounts for approximately 5% of all breast cancer cases, but varies by country. Investigations into the contribution of <it>BRCA </it>mutations to breast cancer incidence in Greece have been, for the most part, limited by small sample sizes and by the use of cases selected for their family history of cancer. The aim of the current study was to estimate <it>BRCA </it>mutation frequencies in breast cancer patients unselected for family history.</p> <p>Methods</p> <p>To do so, we enrolled 127 unselected women with breast cancer from the Alexandra Hospital in Athens, Greece, a large public hospital in the city. Mutations in <it>BRCA1 </it>and <it>BRCA2 </it>were detected using a combination of techniques and were confirmed by direct sequencing. Two large genomic deletions were sought using mutation-specific assays. A detailed family history of cancer was obtained from each patient.</p> <p>Results</p> <p>We were able to successfully complete testing on samples from 127 women. Among these, six mutations were identified (four in <it>BRCA1 </it>and two in <it>BRCA2</it>) representing 4.7% of the total or 9.5% of cases diagnosed before age forty. None of the mutation carriers had a family history of breast or ovarian cancer. Three of the four <it>BRCA1 </it>mutations were in exon 20: two were a G5331A mutation and the third was a 3.2 kb deletion. The fourth <it>BRCA1 </it>mutation was the 3819delGTAAA in exon 11. The two <it>BRCA2 </it>mutations were in exon 11 (3782del10 and 4512insT).</p> <p>Conclusions</p> <p>The G5331A mutation in <it>BRCA1 </it>appears to be a founder mutation in the Greek population.</p

Entwicklung nachhaltiger Pflanzenschutzstrategien zur Bek_mpfung von Schadschmetterlingen im olivenanbau

Current olive growing practices range from the traditional Mediterranean olive grove to intensively managed olive plantations. Insecticides against major olive pests, like the olive moth (Prays oleae, Lep.: Yponomeutidae) and the jasmine moth, (Palpita unionalis, Lep.: Pyralidae) are still applied frequently. The European Union-funded international research project TRIPHELIO is aimed at the development of economically feasible and sustainable insecticide-free control methods for key Lepidopterous pests of olive. Main research activities focus on (1) the use of pheromones for mating disruption and improved monitoring of target pests, (2) habitat management strategies to enhance the activity of natural enemies in the olive grove, and (3) the use of inundative releases of mass-reared egg parasitoids of the genus Trichogramma. Moreover, tools for successful integration of the methods developed into an integrated pest management (IPM) strategy for olive pests were explored by optimising techniques for surveillance as well as considering potential side-effects of common pesticides on beneficial organisms. An intense exchange of scientific information and technology between European and North African countries was undertaken to create solutions for a wide range of olive growing regions. Key results and recommendations for further essential steps towards practical implementation are presented in this publication.Zusammenfassung Traditionelle, extensiv bearbeitete Olivenhaine, aber auch moderne Intensiv-Plantagen mit k_nstlicher Bew_sserung und hohem Einsatz von D_ngern bzw. chemischen Pflanzenschutzmitteln kennzeichnen die derzeitigen verschiedenen Anbauformen der Olive im Mittelmeerraum.

Chemical diversity of gas in distant galaxies: The metal and dust enrichment and variations within absorbing galaxies

The chemical composition of gas in galaxies can be measured in detail from absorption spectroscopy. By studying gas in galaxies in this way, it is possible to investigate the small and faint galaxies, which are the most numerous in the universe. In particular, the chemical distribution of gas in absorbing systems gives us insight into cycles of gas in and around galaxies. Here we study chemical enrichment within 64 Damped Lyman-alpha Absorption (DLA) systems between $1.7 < z < 4.2$. We use high-resolution spectra from VLT/UVES to infer dust depletion from relative abundances of several metals. We perform a component-by-component analysis within DLAs, and characterise variations in their chemical enrichment. Unlike hydrogen, the metal columns can be characterised for individual components. We use them to derive the dust depletion ([Zn/Fe]fit), as an indicator for chemical enrichment. We find that some DLAs are chemically diverse within themselves, with [Zn/Fe]fit ranging up to 0.62 dex within a single system. This suggests that absorbing gas within these galaxies is chemically diverse. Although we do not find a clear trend of decreasing dust depletion with redshift, we do see that the most chemically enriched systems are at lower redshifts. We also observe evidence for dust-poor components at all redshifts, which may be due to the accretion of pristine gas onto galaxies. We combine the chemical and kinematic properties of the individual gas components and observe potential signatures of infalling gas, with low depletion at velocities below $\sim$100km/s, and outflows, with high depletion and velocities of $\sim$600km/s. We find over-abundances of alpha-elements (an enhancement of $\sim$0.3dex) and under-abundances of Mn in several components, which is likely a signature of core-collapse SNe nucleosythesis in the ISM. We observe these effects mostly at lower levels of chemical enrichment.Comment: 56 pages, 99 figures, Accepted for publication in A&A, Abstract abridged for arXi
