Knowledge Management & Loyalty Programs: A Customer Perception Analysis, the Greek Retail Market

The Food Retail sector in Greece is currently facing a number of challenges. From an economic point of view, the austerity programs imposed in Greece since 2010 resulted in losses of retail sales, alongside with bankruptcies and mergers of retail chains. At the same time, technological development creates an environment for innovation in terms of operations and marketing and offers new opportunities to retailers. Additionally, consumers become more involved and active in the purchasing processes. However, Greek consumers are also experiencing a dramatic decline in their disposable income. The study examines the perception of Greek consumers of several marketing efforts based on Information & Communication Technology Systems (ICT) introduced by a Greek food retailer in Northern Greece. More specifically, it investigates the relationship between ICT related marketing efforts, such as loyalty programs, and analytics regarding food control systems and purchases and consumer characteristics such as gender, age, income, status and family size. The study reveals a number of relationships between marketing efforts and consumer characteristics/segments. However, since the relationships are found to be weak, marketing managers are advised to use advanced analytics systems, such as big data technologies, in order to enhance the efficiency of their marketing strategies and approaches. The weak relationships between the parameters examined indicate that marketing efforts have to focus in several consumer sub segments in order to achieve significant results. The study’s sample population is consumers of one of the top food retailers in Greece. The findings contribute to the literature on the use of ICT on marketing strategies and the use of big data. Furthermore, they have practical implications for marketers in the retail food sector, as they reveal the need for a more focused approach to different consumer groups, in order to increase the efficiency of marketing efforts and to achieve maximum results.     Keywords: knowledge management, loyalty programs, ICT, segmentatio

Molecular and cellular mechanisms underlying the evolution of form and function in the amniote jaw.

The amniote jaw complex is a remarkable amalgamation of derivatives from distinct embryonic cell lineages. During development, the cells in these lineages experience concerted movements, migrations, and signaling interactions that take them from their initial origins to their final destinations and imbue their derivatives with aspects of form including their axial orientation, anatomical identity, size, and shape. Perturbations along the way can produce defects and disease, but also generate the variation necessary for jaw evolution and adaptation. We focus on molecular and cellular mechanisms that regulate form in the amniote jaw complex, and that enable structural and functional integration. Special emphasis is placed on the role of cranial neural crest mesenchyme (NCM) during the species-specific patterning of bone, cartilage, tendon, muscle, and other jaw tissues. We also address the effects of biomechanical forces during jaw development and discuss ways in which certain molecular and cellular responses add adaptive and evolutionary plasticity to jaw morphology. Overall, we highlight how variation in molecular and cellular programs can promote the phenomenal diversity and functional morphology achieved during amniote jaw evolution or lead to the range of jaw defects and disease that affect the human condition

Introductory programming: a systematic literature review

As computing becomes a mainstream discipline embedded in the school curriculum and acts as an enabler for an increasing range of academic disciplines in higher education, the literature on introductory programming is growing. Although there have been several reviews that focus on specific aspects of introductory programming, there has been no broad overview of the literature exploring recent trends across the breadth of introductory programming. This paper is the report of an ITiCSE working group that conducted a systematic review in order to gain an overview of the introductory programming literature. Partitioning the literature into papers addressing the student, teaching, the curriculum, and assessment, we explore trends, highlight advances in knowledge over the past 15 years, and indicate possible directions for future research

A proposal for a CT driven classification of left colon acute diverticulitis

Computed tomography (CT) imaging is the most appropriate diagnostic tool to confirm suspected left colonic diverticulitis. However, the utility of CT imaging goes beyond accurate diagnosis of diverticulitis; the grade of severity on CT imaging may drive treatment planning of patients presenting with acute diverticulitis. The appropriate management of left colon acute diverticulitis remains still debated because of the vast spectrum of clinical presentations and different approaches to treatment proposed. The authors present a new simple classification system based on both CT scan results driving decisions making management of acute diverticulitis that may be universally accepted for day to day practice

The normal field instability under side-wall effects: comparison of experiments and computations

We consider a single spike of ferrofluid, arising in a small cylindrical container, when a vertically oriented magnetic field is applied. The height of the spike as well as the surface topography is measured experimentally by two different technologies and calculated numerically using the finite element method. As a consequence of the finite size of the container, the numerics uncovers an imperfect bifurcation to a single spike solution, which is forward. This is in contrast to the standard transcritical bifurcation to hexagons, common for rotational symmetric systems with broken up-down symmetry. The numerical findings are corroborated in the experiments. The small hysteresis observed is explained in terms of a hysteretic wetting of the side wall.Comment: accepted to New Journal of Physic
