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

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

Evaluating New Approaches of Intervention in Reading Difficulties in Students with Dyslexia: The ilearnRW Software Application

The aim of this paper is to increase knowledge and understanding on how the implementation of language content through specialized software, such as the “Integrated Intelligent Learning Environment for Reading and Writing-iLearnRW”, can enhance learning during intervention procedures to enhance reading skills for children with dyslexia.The iLearnRW software is a newly designed tool that makes use of innovative technology and provides individualized intervention through games that incorporate learning activities, addressing those language areas that are most challenging for children with dyslexia in a highly entertaining and motivating way. Individualized intervention is provided through an underlying user profile, which incorporates these language features and is constantly updated as the child uses the software playing games, presenting language material selected based on his difficulties and recording his progress. A group of 78 students (52 male, 26 female) diagnosed with dyslexia, aged between 9 and 11 years old, was assessed for phonological, morphological and vocabulary skills. The students logged in the iLearnRW software on a mean of 14.18 days over a six-month intervention. After the 6-month intervention, the students were assessed once again on the same skills so as to establish the tool’s effectiveness.The results’ analysis revealed the following: (i) there was a strong constructional linkage between the profile entries of the sample, the language content of the tasks of the screening test as well of the games and its effectiveness in the students’ performance; (ii) the students who received specific guidance by their teachers, obtained higher success rates in most of the games than the students without any guidance, and (iii) the quantity of the language content and the time playing were not correlated with the students’ performance in the software’s games. Keywords: Digital technology, assistive computer software, dyslexia, learning environmen

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

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
