Guerrilla Marketing Technique Effectiveness: A Quantitative Experiment

In the past, guerrilla marketing was about getting maximum impact for the least amount of advertising dollars. Now, big companies are spending substantial amounts of money on campaigns that are more subtle and can appear ‘grassroots’ to consumers. Guerrilla marketing as an emerging field encompasses many specific techniques a marketer can use to untraditionally, creatively, and inexpensively promote their business. However, part of being an emerging field means there is a lack of literature and research that digs deep into the specifics of technique effectiveness within guerrilla marketing. This thesis outlines the use of guerrilla marketing techniques today, and conducts a quantitative experiment in hopes of gleaning which of three guerrilla marketing categories (as outlined by the researchers) is most effective at reaching a student target group. Managerial implications and a cost-efficiency discussion is also included to help define a starting point for future research

Scene integration for online VR advertising clouds

This paper presents a scene composition approach that allows the combinational use of standard three dimensional objects, called models, in order to create X3D scenes. The module is an integral part of a broader design aiming to construct large scale online advertising infrastructures that rely on virtual reality technologies. The architecture addresses a number of problems regarding remote rendering for low end devices and last but not least, the provision of scene composition and integration. Since viewers do not keep information regarding individual input models or scenes, composition requires the consideration of mechanisms that add state to viewing technologies. In terms of this work we extended a well-known, open source X3D authoring tool

Προσφυγική κρίση - Σύγχρονη μετανάστευση μέσω εθνικών χωρικών υδάτων

Η Ελλάδα αποτελεί μία από τις κύριες πύλες εισόδου προσφύγων και μεταναστών από τρίτες χώρες προς την Ευρώπη, λόγω της κρίσιμης γεωγραφικής της θέσης στα νοτιοανατολικά σύνορα της ΕΕ, καθώς αποτελεί το σταυροδρόμι και τη φυσική γέφυρα τριών ηπείρων (Ευρώπης, Ασίας και Αφρικής). Η κοινωνικοπολιτική-οικονομική αστάθεια και οι συνεχιζόμενες συρράξεις στις τρίτες χώρες, και ιδίως στη Μέση Ανατολή, έχουν προκαλέσει τα τελευταία έτη μια άνευ προηγουμένου μαζική μετατόπιση πληθυσμών, την οποία η χώρα μας, ως πρώτη χώρα υποδοχής, καλείται να διαχειρισθεί. Η διέλευση μεικτών μεταναστευτικών ροών από μη θεσμοθετημένα σημεία των θαλασσίων συνόρων της χώρας πραγματοποιείται κυρίως τις δυο τελευταίες δεκαετίες. Ειδικότερα, το 2015, λόγω των δυσμενών γεωπολιτικών εξελίξεων, το φαινόμενο αυτό προσέλαβε ανυπολόγιστες διαστάσεις στα νησιά του Ανατολικού Αιγαίου, όταν τεράστια μεταναστευτικά-προσφυγικά ρεύματα υπηκόων τρίτων χωρών εισήλθαν στην Ευρώπη μέσω των ανατολικών θαλασσίων συνόρων και των εθνικών χωρικών υδάτων της Ελλάδας. Στο παρόν πόνημα γίνεται αναφορά στις σχετιζόμενες με τη μετανάστευση και την προσφυγική κρίση έννοιες και παρουσιάζεται το μεταναστευτικό φαινόμενο των τελευταίων ετών, ιδιαίτερα για την περίοδο κορύφωσής του κατά το έτος 2015, οπότε και υπήρξε γεωμετρικός πολλαπλασιασμός των ανθρώπινων ροών προς τα θαλάσσια σύνορα της Ελλάδας και κατ’ επέκταση της ΕΕ. Παράλληλα, αναφέρονται οι βασικές πτυχές του προβλήματος και οι λόγοι και οι αιτίες που οδήγησαν πλήθος ανθρώπων να μετακινηθούν από την πατρίδα τους, αναζητώντας ένα καλύτερο και ασφαλέστερο περιβάλλον στις χώρες της Ευρώπης. Επιπρόσθετα, παρέχονται στοιχεία που αφορούν την Ελλάδα, η οποία έχει επιβαρυνθεί με ένα μεγάλο μέρος των μεταναστών, λόγω της γεωγραφικής της θέσης, όπως άλλωστε και ολόκληρος ο ευρωπαϊκός Νότος. Επιχειρείται η διερεύνηση και η εμβάθυνση στο φαινόμενο της παράτυπης μετανάστευσης και ιδιαίτερα στα αίτια που την προκαλούν, στη διαχείρισή της, καθώς και στα ζητήματα ασφαλείας που ανακύπτουν από τον όγκο και τη μορφή που έχει λάβει στις ημέρες μας. Η παρούσα εργασία στο ακροτελεύτιο τμήμα της, λαμβάνοντας υπόψη συγκεντρωτικά τα στοιχεία, επιχειρεί να προβεί σε εξαγωγή συμπερασμάτων, να αναδείξει τις καλές πρακτικές και, με τη γνώση των λαθών και των ελλείψεων του παρελθόντος, να προτείνει ιδέες και λύσεις στο πλαίσιο συνεισφοράς στην αντιμετώπιση του φαινομένου της μετανάστευσης, το οποίο σίγουρα δεν τελείωσε.Greece is one of the main gateways for refugees and immigrants from third countries to Europe due to its geographical location at the EU's southeastern border. It is a transcontinental country at the crossroads of Europe, Asia and Africa. The socio-political and economic instability and ongoing conflicts in third countries, especially in the Middle East, have led to an unprecedented massive population shifting, which our country, as the first host country, is called to manage. The passage of mixed migratory flows from unregulated points of the country's maritime borders has been taking place mainly during the last two decades. In particular, in 2015, due to unfavorable geopolitical developments, this phenomenon has taken on huge dimensions in the eastern Aegean islands. Huge migratory-refugee flows of third-country nationals have entered Europe through the eastern maritime borders and national territorial waters of our country. In this paper, reference is made to the related concepts of immigration and the refugee crisis and the migration phenomenon of recent years, especially for its peak in the year 2015, where there was a geometric proliferation of human flows to the sea borders of Greece and consequently of the EU. At the same time, they are the key aspects of the problem and the reasons and the causes that led many people to move from their homeland in search of a better and safer environment in European countries. In addition, provide data concerning Greece, which is burdened with a large proportion of immigrants, due to its geographical position, as is the whole of the European South. It seeks to investigate and deepen the phenomenon of irregular immigration, and especially the causes of it, in its management, and the security issues arising from the volume and form it has taken today. The present study on the final part, taking account of aggregate data, is attempting to make inferences, to highlight good practices and with the knowledge of the mistakes and past failures, to propose ideas and solutions under contribution in addressing the phenomenon of immigration, which is certainly not over

Effects of designed PLLA and 50:50 PLGA scaffold architectures on bone formation in vivo

Biodegradable porous scaffolds have been investigated as an alternative approach to current metal, ceramic, and polymer bone graft substitutes for lost or damaged bone tissues. Although there have been many studies investigating the effects of scaffold architecture on bone formation, many of these scaffolds were fabricated using conventional methods such as salt leaching and phase separation, and were constructed without designed architecture. To study the effects of both designed architecture and material on bone formation, this study designed and fabricated three types of porous scaffold architecture from two biodegradable materials, poly (L‐lactic acid) (PLLA) and 50:50 Poly(lactic‐co‐glycolic acid) (PLGA), using image based design and indirect solid freeform fabrication techniques, seeded them with bone morphogenetic protein‐7 transduced human gingival fibroblasts, and implanted them subcutaneously into mice for 4 and 8 weeks. Micro‐computed tomography data confirmed that the fabricated porous scaffolds replicated the designed architectures. Histological analysis revealed that the 50:50 PLGA scaffolds degraded but did not maintain their architecture after 4 weeks implantation. However, PLLA scaffolds maintained their architecture at both time points and showed improved bone ingrowth, which followed the internal architecture of the scaffolds. Mechanical properties of both PLLA and 50:50 PLGA scaffolds decreased but PLLA scaffolds maintained greater mechanical properties than 50:50 PLGA after implantation. The increase of mineralized tissue helped support the mechanical properties of bone tissue and scaffold constructs between 4–8 weeks. The results indicate the importance of choice of scaffold materials and computationally designed scaffolds to control tissue formation and mechanical properties for desired bone tissue regeneration.

Non-reducible knee dislocation with interposition of the vastus medialis muscle

Irreducibility of the knee following complete dislocation is a rare event determined by the interposition of various capsulo-ligamentous structures in the joint space. Such cases often require urgent surgical treatment. We report the case of a healthy 70-year-old man with a sprain of the left knee that occurred after a sports trauma. The patient showed knee dislocation with multiple ligamentous injuries and articular block due to interposition of a portion of the vastus medialis muscle. After arthroscopic evaluation, we performed surgical treatment to free the muscle, regularize the medial meniscus and suture the posterior and medial capsule and ligaments; the cruciate ligaments were not treated. The most interesting aspect of the articular damage in this case was a wide detachment of the vastus medialis muscle with intra-articular dislocation. The decision to treat only the posterior lesions and allow the healing of the front ones by rehabilitation treatment was supported by full functional recovery and return to sports activity

Shoulder hemiarthroplasty for fractures of the proximal humerus

Proximal humeral fractures were managed with primary hemiarthroplasty in 57 patients, 53 women (93%) and 4 men (7%) aged 51–87 years (mean 72.2). The mean follow-up period was 52 months (range 12–98), and the mean Constant score was 59.2 (range 38–76). Patients were very satisfied (n = 19); satisfied (n = 32) or dissatisfied with the outcome (n = 5). One patient required early revision surgery. Surgical treatment of three- and four-part fractures of the proximal humerus with hemiarthroplasty is a safe and effective approach, the outcome of which appears to be related to the quality of the anatomical reconstruction of the tuberosities
