Products and Markets – The Activities of the Imperial Guilds of Constantinople

AbstractIn the present paper the questions that are covered concern specific entrepreneurial aspects of the imperial guilds in Constantinople of the 10th century. The mentioned aspects are dealing first with the products and services offered by the guilds and secondly with the places, streets and areas where the guild members allowed to do their business. All this information is stated in the Book of the Eparch (BE) or Book of the Prefect («Tο Eπαρχικóν Bιβλίον»). Accordingly we are analyzing first the structure and quantity of the products / services mentioned in the Book of Eparch (BE) and next we are mentioning the used locations prescribed by the Prefect himself. Therefore the investigation analyses the products / services as well as the places connected with each of the products and services that are sold there

The Promotion of Eating Behaviour Change through Digital Interventions.

Diet-related chronic disease is a global health epidemic giving rise to a high incidence of morbidity and mortality. With the rise of the digital revolution, there has been increased interest in using digital technology for eating behavioural change as a mean of diet-related chronic disease prevention. However, evidence on digital dietary behaviour change is relatively scarce. To address this problem, this review considers the digital interventions currently being used in dietary behaviour change studies. A literature search was conducted in databases like PubMed, Cochrane Library, CINAHL, Medline, and PsycInfo. Among 119 articles screened, 15 were selected for the study as they met all the inclusion criteria according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) search strategy. Four primary digital intervention methods were noted: use of personal digital assistants, use of the internet as an educational tool, use of video games and use of mobile phone applications. The efficiency of all the interventions increased when coupled with tailored feedback and counselling. It was established that the scalable and sustainable properties of digital interventions have the potential to bring about adequate changes in the eating behaviour of individuals. Further research should concentrate on the appropriate personalisation of the interventions, according to the requirements of the individuals, and proper integration of behaviour change techniques to motivate long-term adherence

The Phenomenon of Homelessness during the Greek Economic Crisis 2009-2018

This research focuses on the phenomenon of homelessness in Greece, especially during the deep economic crisis that has lasted from 2009 until this day. Unfortunately, in large part, homelessness also affects welfare policy, as well as social cohesion and healthcare. The significance of the study lies in the fact that there are no official data from governmental institutions concerning the number of homeless people across the country. For this reason, this study attempts to collect all available data in order to present the evolution of the phenomenon of homelessness from 2009 to present. Homelessness is examined in relation to poverty and other factors of deprivation. In addition, countermeasures addressing homelessness, adopted by both public and private organizations, are also examined. Public institutions usually provide small pensions, only for seniors over sixty-seven years old, meal cards, free soup kitchens and several shelters. At the same time, a large number of private organizations, such as NGOs, provide free accommodation, meals, and showers. Unfortunately, the rising number of homeless people during the ongoing socioeconomic crisis and the lack of communication among institutions deteriorate the problem. On these grounds, this research analyzes the phenomenon of homelessness in Greece in order to provide the appropriate solutions for its containment

The Patterns of High-Level Magnetic Activity Occurring on the Surface of V1285 Aql: The OPEA Model of Flares and DFT Models of Stellar Spots

Statistically analyzing Johnson UBVR observations of V1285 Aql during the three observing seasons, both activity level and behavior of the star are discussed in respect to obtained results. We also discuss the out-of-flare variation due to rotational modulation. Eighty-three flares were detected in the U-band observations of season 2006 . First, depending on statistical analyses using the independent samples t-test, the flares were divided into two classes as the fast and the slow flares. According to the results of the test, there is a difference of about 73 s between the flare-equivalent durations of slow and fast flares. The difference should be the difference mentioned in the theoretical models. Second, using the one-phase exponential association function, the distribution of the flare-equivalent durations versus the flare total durations was modeled. Analyzing the model, some parameters such as plateau, half-life values, mean average of the flare-equivalent durations, maximum flare rise, and total duration times are derived. The plateau value, which is an indicator of the saturation level of white-light flares, was derived as 2.421{\pm}0.058 s in this model, while half-life is computed as 201 s. Analyses showed that observed maximum value of flare total duration is 4641 s, while observed maximum flare rise time is 1817 s. According to these results, although computed energies of the flares occurring on the surface of V1285 Aql are generally lower than those of other stars, the length of its flaring loop can be higher than those of more active stars.Comment: 44 pages, 10 figures, 5 tables, 2011PASP..123..659

Therapeutic Management: When and What

Migraine is a widespread brain disease that is classified as the second most disabling condition and has the third highest prevalence of all medical conditions. Despite its non-emergent or life-threatening nature, migraine can progress to chronic type, a subform associated with significant morbidity and drug overuse. In the management of migraine, it is important therefore to introduce early prophylactic treatment in order to limit migraine chronification. In this chapter, we will go through all the treatment options, both acute and preventive, pharmaceutical and non-pharmaceutical following this flowchart: 1. Introduction; 2. General principles; 2.1 Symptomatic therapy; 2.2 Prophylactic management; 3. Pharmaceutical therapies; 3.1 Symptomatic; 3.1.1 Disease-specific; 3.1.2 No disease-specific; 3.2 Prophylactic; 3.2.1 Disease-specific; 3.2.2 No disease-specific; 3.3 Non-Pharmaceutical therapies; 3.4 Neuromodulation; 3.4.1 Invasive; 3.4.5 Non-invasive; 3.5 Nutrient (nutraceuticals); 3.6 Dietary interventions; 3.7 Acupuncture; 3.8 Physical therapy; 4. Cognitive behavioral therapies; 5. Patient centricity and patient education
