This paper surveys the results established so far by the on-going research on the planetary theories in Arabic astronomy. The most important results of the Maragha astronomers are gathered here for the first time, and new areas for future research are delineated. The conclusions reached demonstrate that the Arabic astronomical works mentioned here not only elaborate the connection between Arabic astronomy and Copernicus, but also that such activities, namely the continuous reformulation of Greek astronomy, were not limited to a specific group of astronomers or to a specific geographical area. It is shown that such activities were spread over a period of more than seven hundred years, from the early eleventh till the sixteenth century, and over an area stretching from the Andalusian peninsula in the west to the farthest reaches of Central Asia in the east.

Purpose – Examination of Pro-Environmental Purchasing Behaviour (PPB) and its potential components. Investigation of the number and the size of relevant consumer segments. Determining the factors able to describe the segment of frequent pro-environmental purchasers. This paper aims to discuss these issues. Design/methodology/approach – Investigation of PPB as a total multi-item variable. Disclosure of the PPB components. Examination of the Purchase component and disclosure of its clusters. Focus on the cluster of frequent purchasers. Estimation of the demographic, attitudinal and psychographic variables able to describe and predict these consumers. Findings – Two components of PPB were found, namely Conservation (high consumer engagement in this) and Purchase (low consumer engagement in this). Inside the Purchase component of PPB three clusters were found, indicating, respectively, low, average and relatively high consumers’ involvement. Consumers in Cluster 3 (frequent pro-environmental purchasers) are fewer than in the past. They were found to be negatively influenced by environmental unconcern attitudes and Materialism, while they were positively affected by locus of control over politics and Universalism. Research limitations/implications – No demographic profile of frequent purchasers. Geographical area limited (a potential) generalisation of results. Social desirability effect. Future research with reference to evolutions in pro-environmental post-purchasing or non-purchasing behaviours during the years of economic crisis. Practical implications – Fewer consumers would buy ecological products if these were not comparable enough with the conventional products in terms of price and efficacy. Originality/value – First effort to explore the impact of the economic crisis on PPB in Greece. Encompassed new categories of ecological products. Revealed two components inside PPB (Purchase and Conservation) as well as number and size of consumer segments inside the Purchase component. Formulation of a partial profile of the frequent pro-environmental purchasers. Impact of Universalism on PPB was for the first time examined.

The article provides an overview (both in terms of types and amount) of liturgical paraphernalia (vessels, vestments, and processional items), musical instruments (organs and bells), and other items of church interior (pews, candlesticks, chandeliers, commemorative plaques, sacristy furniture, boxes for holy oils, offering boxes, wallpapers, sepulchral banners, and stoups) extant in the parish churches of the diocese of Samogitia in the first half of the seventeenth century. The overview is based on the information contained in visitation acts and inventories due to the fact that only a few material pieces of sacral art dating back to the mentioned period have survived until now. Historical sources enabled a description of the whole repertoire of liturgical paraphernalia of the parish churches of the above-mentioned diocese (in the first half of the seventeenth century) for the first time. The overview reveals some transformations of the older practice, occasionally witnessed in local sources of the sixteenth century. More significantly, it enables future research based on a comparison of the described material with the information contained in wider chronological and geographical (first of all, including the diocese of Vilnius) contexts.

Introduction: Anisakidosis is a zoonotic disease caused by the consumption of raw or undercooked fish or crustaceans parasitized by nematode larvae of the Anisakidae family. In this study, the presence of anisakid larvae was identified in fish species of consumer of the Pacific coast in Ecuador and Colombia.Methods: We obtained 438 samples grouped into twenty species of fish caught in the fishing ports of Manta, Santa Rosa, Buenaventura and Tumaco. The morphological identification of the larvae was made by taxonomy and the percentage of infection, were calculated. For the identification of species, a multiplex PCR was carried.Results: The taxonomic review identified eight species of fish as hosts of the genders Anisakis andPseudoterranova. The larvae were isolated mainly from  the intestine with a percentage of infection between 18 and 100%. The percentage of infection and identification of anisakids in these fish will aid in the prevention and control of anisakiasis as a possible emerging disease for this area of the Pacific. With the multiplex PCR, A. pegreffii, A. physeteris, and P. decipiens were identified.Conclusion: The identification of these species is reported for the first time in this geographical area, providing the basis for future research into the Anisakidae family.

The genus Stachybotrys produces a broad diversity of secondary metabolites, including macrocyclic trichothecenes, atranones, and phenylspirodrimanes. Although the class of the phenylspirodrimanes is the major one and consists of a multitude of metabolites bearing various structural modifications, few investigations have been carried out. Thus, the presented study deals with the quantitative determination of several secondary metabolites produced by distinct Stachybotrys species for comparison of their metabolite profiles. For that purpose, 15 of the primarily produced secondary metabolites were isolated from fungal cultures and structurally characterized in order to be used as analytical standards for the development of an LC-MS/MS multimethod. The developed method was applied to the analysis of micro-scale extracts from 5 different Stachybotrys strains, which were cultured on different media. In that process, spontaneous dialdehyde/lactone isomerization was observed for some of the isolated secondary metabolites, and novel stachybotrychromenes were quantitatively investigated for the first time. The metabolite profiles of Stachybotrys species are considerably influenced by time of growth and substrate availability, as well as the individual biosynthetic potential of the respective species. Regarding the reported adverse effects associated with Stachybotrys growth in building environments, combinatory effects of the investigated secondary metabolites should be addressed and the role of the phenylspirodrimanes re-evaluated in future research.

AbstractThe need for qualitative research of deservingness perception is strongly emphasised in the literature. This article studies the perception of deservingness for a "Family 500 +"—cash benefit in Poland. For the first time, data from online forums was used in the studies of deservingness and welfare attitudes. It allowed to avoid numerous limitations associated with social surveys. The qualitative analysis showed how participants of Internet debates perceive the criteria of deservingness: control, attitude, reciprocity, identity, need, and what are the relations between the criteria. The impurity of all deservingness criteria was indicated and a new criterion “adequacy” was proposed. Moreover due to the fact that the study concerned a concrete, non-abstract family cash benefit addressed the relationship between the perceived deservingness of children and their parents was pointed out. The vast majority of posts on Internet forums referred to deservingness of parents, not children. This is particularly evident in relation to the criteria of control and reciprocity. Presenting the hypothesis of jealousy and scapegoat strategy, the article also shows the direction of future research on deservingness.

John Mauropous, an eleventh-century Metropolitan of Euchaïta, has long been commemorated in the service books of the Orthodox Church. The Synaxarion for the Office of Orthros on 30th January, the day dedicated to the Three Fathers, St. Basil the Great, St. Gregory the Theologian, and St. John Chrysostom, tells how the festival was instituted by Mauropous and describes him as ‘the well-known John, a man of great repute and well-versed in the learning of the Hellenes, as his writings show, and moreover one who has attained to the highest virtue’. In western Europe something was known of him certainly as early as the end of the sixteenth century; his iambic poems were published for the first time by an Englishman in 1610, and his ‘Vita S. Dorothei’ in the Acta Sanctorum in 1695. But it was not until the second half of the nineteenth century that scholars were really able to form some idea of the character and achievement of this Metropolitan of Euchaïta. Particularly important were two publications: Sathas' edition in 1876 of Michael Psellus' oration on John, and Paul de Lagarde's edition in 1882 of some of John's own writings. This last contained not only the works already printed, but a number of hitherto unpublished sermons and letters, together with the constitution of the Faculty of Law in the University of Constantinople, and a short introduction containing part of an etymological poem. But there remained, and still remains, one significant omission: John's canons have been almost consistently neglected.


This book is a ground-breaking study of the phenomenon of migration in and to England over the medieval millennium, between c. AD 500 and c. AD 1500. It reaches across traditional scholarly divides, both disciplinary and chronological, to investigate, for the first time, the different types of data and scholarly methods that reveal evidence of migration and mobility within the medieval kingdom of England. England offers the opportunity for studying migration and migrants over the longue durée, because it has been a recognisable political unit for over a millennium and because a wealth of source material has survived from these centuries. The data vary unevenly in quality and quantity across this period, but become considerably more powerful through multi-disciplinary approaches to data collection and interpretation. Fifteen subject specialists synthesise and extend recent research in a wide range of disciplines, including archaeology, art history, genetics, historical linguistics, history, literature and onomastics. They evaluate the capacity of different genres of evidence for addressing questions around migration and its effects on the identities of groups and individuals within medieval England, as well as methodological parameters and future research potential. The book therefore marks an important contribution to medieval studies, and to modern debates on migration and the free movement of people, arguing that migration in the modern world, and its reverberations, cannot be completely understood without taking a broad historical perspective on the topic.


The Canadian prescription process requires a person to go through several steps. Prescription medications have associated risks and benefits and it is important for people to be aware of these before and while they are taking medications. One of the approaches to informing people about new prescription medications is that they are provided Consumer Medication Information (CMI). CMI is given to Canadians at the pharmacy when they pick up prescriptions, they will be taking for the first time. This study used semi-structured interviews to examine the lived experiences of a sample of Canadians (N = 36) to identify opportunities for improvement in how and when they are informed about new prescription medications. The findings were synthesized into a journey map. Generally, participants wanted to receive CMI digitally and earlier in the prescription process. Adopting these changes could have several benefits which include loss prevention and increased accessibility to CMI as well as more participatory decision making and opportunities to ask questions. Future research is warranted to explore similar topics with a larger sample and determine what method (e.g., email, website, mobile application) would be most suitable.

The expectations induced by the labels used to describe vehicle automation are important to understand, because research has shown that expectations can affect trust in automation even before a person uses the system for the first time. An online sample of drivers rated the perceived division of driving responsibilities implied by common terms used to describe automation. Ratings of 13 terms were made on a scale from 1 (“human driver is entirely responsible”) to 7 (“vehicle is entirely responsible”) for three driving tasks (steering, accelerating/braking, and monitoring). In several instances, the functionality implied by automation terms did not match the technical definitions of the terms and/or the actual capabilities of the automated vehicle functions currently described by the terms. These exploratory findings may spur and guide future research on this under-examined topic.
