Orchids in the Roman culture and iconography: Evidence for the first representations in antiquity

Orchids have fascinated humans since ancient times. Not only the particular morphology of their flowers and hypogean organs, but also their reproductive biology have inspired myths, legends and popular traditions in many cultures, all around the world. Despite these facts, their representations on ancient artefacts have never been described in the scientific literature. No clear data exist for Eastern culture, and in Western countries, the first certain representations of orchids in art date back to the XV-XVI century CE. This paper documents different identifications of orchids on Roman monuments changing the common belief that these plants first appeared in art more recently. Floral elements of Cephalanthera spp., Spiranthes spiralis (L.) Chevall, of Orchis tridentata Scop., and of other orchids were observed in different architectonical elements (cornices and ceilings) throughout the Roman period, and in the external frieze of the Ara Pacis monument (I century CE). These representations seem to refer to a symbolism of fertility and sexuality, and their absence in medieval time can be explained only considering religion influences.     

(Re-)designing higher education curricula in times of systemic dysfunction: a responsible research and innovation perspective

There is an urgent need to address the grand sustainability challenges of our time, and to explore new and more responsible ways of operating, researching, and innovating that enable society to respond to these challenges. The emergent Responsible Research and Innovation (RRI) policy agenda can act as a catalyst towards the development of new and more responsible research and innovation efforts. Inevitably, higher education needs to be closely attuned to this need and agenda, by preparing students to engage in RRI efforts. This paper makes a first step towards guiding the embedding of RRI within higher education. It does so by bringing together academic knowledge with phronesis or practical knowledge about what should be done in an ethical, political, and practical sense. It draws on a literature review and on the reflective practices of partners in the European Commission funded project EnRRICH (Enhancing Responsible Research and Innovation through Curricula in Higher Education), as well as on interviews and case studies gathered as part of the project. The paper suggests elements, especially design principles and a competence framework, for (re)designing curricula and pedagogies to equip higher education students to be and to become responsible actors, researchers, and innovators in a complex world, and to address grand sustainability challenges. In addition, this paper proposes that contemporary higher education teaching and learning policies and strategies, especially those promoting neoliberal agendas and marketized practices, need to adopt a more responsible and responsive ethos to foster the renewal of higher education in times of systemic dysfunction.     

Primary school heads’ professional socialization and leadership development in Cyprus

This article explores Cypriot primary school heads’ professional socialization (PS), in terms of their preparation for headship. A study in three phases involving a survey and interviews indicates that, to ‘learn what it is to be a head’ prior to headship, Cypriot heads resort to personal initiatives for training and development in school management and leadership; deputy headship, along with practising leadership in small primary schools, also appears to contribute to PS. In light of these experiences, heads take up headship with some preconceptions about the headship role. Upon entry to headship, networking and collaboration, as well as the formal training scheme for newly appointed school heads are also considered as useful, but heads set directions in which this programme could further be enhanced. In view of these findings, leadership development could address the contribution of previous heads, counterparts, colleagues, mentors and trainers to Cypriot school heads’ PS in both preparation as well as induction programmes.     

Learning Documentations in VET Systems: An Analysis of Current Swiss Practices

Swiss vocational education and training (VET) is defined as a dual-track system where apprentices weekly alternate between vocational school and a (real) workplace. At the workplace, they have to keep a learning documentation throughout their training, in which they are expected to regularly document their professional development. The actual use of this documentation remains limited, however, and its potential for learning is clearly underexploited. The study presented in this paper sheds light on the current practices and issues related to the use of such a learning documentation in the Swiss VET system. Semi-structured interviews (N?=?29) were conducted with representatives of all the main actors of the Swiss VET system for various professional domains (Industrial & Handicraft, Commerce, and Health & Social Care). The study shows that although they all tend to see the potential of the learning documentation, the different actors of VET do not share a same conception of the aims and functions, both within and across professions. Based on their answers, possible improvements for this tool are discussed, and suggestions are made to enhance its use as a boundary object throughout the training.     

Spectroscopic analyses of Hellenistic painted plasters from 2nd century B.C., Sicily (South Italy)

In the present work, an analytical characterization of painted plaster samples coming from ancient buildings dated back to 2nd cent. B.C., located in Licata (Sicily, Southern Italy), has been carried out. The investigation has been performed through different spectroscopic techniques: X-ray fluorescence (XRF) using an handheld energy-dispersive XRF analyzer, scanning electron microscopy equipped with an Energy Dispersive Spectrometry microanalysis detector (SEM-EDS) and Fourier transform infrared absorbance spectroscopy (FT-IR). The main goal is to identify the plaster and pigments material. In particular, the XRF investigation of surfaces is the first step for a preliminary elemental characterization. Then, through SEM-EDS measurements, a quantitative analysis of the chemical composition of the plaster and the pigmenting agents along with eventual components related to deterioration processes has been obtained. Finally, FT-IR absorbance spectra have proven to be a useful tool to investigate the molecular nature of the used materials.     

Micro-political practices in higher education: a challenge to excellence as a rationalising myth?

ABSTRACT

Excellence has become a ‘hoorah’ word which is widely used in higher education institutions to legitimate practices related to the recruitment/progression of staff. It can be seen as reflecting an institutionalised belief that such evaluative processes are unaffected by the social characteristics of those who work in them or their relationships with each other. Such views have been challenged by gender theorists and by those researching informal power in state structures. The purpose of this article is to raise the possibility that excellence is an ‘idealised cultural construct’ and a ‘rationalising myth’. Drawing on data from qualitative interviews with 67 men and women, who were candidates or evaluators in recruitment/progression processes in five higher educational institutions (in Ireland, Turkey, Bulgaria, Germany and Italy), it conceptualises and illustrates masculinist, relational and ‘local fit’ micro-political practices that are seen to affect such recruitment/progression. Variation exists by gender and by contextual positioning in the process (i.e. as evaluator/candidate). These practices illustrate the perceived importance of the enactment of informal power. The article suggests that the construct of excellence is used to obscure these practices and to maintain organisational legitimacy in the context of multiple stakeholders with conflicting expectations.     

The impact of study attitudes and study behaviour on satisfaction of online students with the implementation of online study programmes

The main objective of the research was to analyse the study attitudes and study behaviour of online students at DOBA Business School. Furthermore, the aim was to evaluate the interrelationship between study attitudes and study behaviour and to assess the predictive value of the two sets of variables for students’ general satisfaction with the study programmes. A total of 331 students participated in the web survey. Participants expressed the most positive attitudes towards the use of technology and flexibility of online learning, while the absence of personal contacts was also perceived as highly favourable. Average scores for both deep and strategic approaches were quite high, while the surface approach was much less prominent . Participants were highly engaged with their teamwork assignments, whereas proactive communication was somewhat less developed . Study attitudes seem to be far more powerful predictors of general satisfaction than study behaviour, which is not surprising. Satisfaction is thought to be the result of the complex subjective evaluation of all relevant aspects of the study programme implementation, as they were measured by attitudinal subscales.     

Women in sports: the applicability of common national reference intervals for inflammatory and coagulation biomarkers (HemSter Study)

IntroductionIntensive physical activity causes functional and metabolic changes in the athlete’s organism. The study aimed to verify the common national available reference intervals (RIs) for common inflammatory and screening coagulation tests in a population of healthy young female athletes.Materials and methodsOne hundred and twenty-one female athletes (age range: 16–34), from various sports disciplines (water polo, handball, volleyball, football, basketball), were included in the study. All participants completed the international physical activity short-form questionnaire. Blood samples were collected between 8–10 am, after an overnight fast, before any physical activity. Reference intervals were determined according to Clinical & Laboratory Standards Institute EP28-A3C Guidelines.ResultsCalculated RIs for white blood cell count (WBC), prothrombin time (PT), and activated partial thromboplastin time (APTT) ratio were in accordance with the common national RIs. Calculated RI for C-reactive protein (CRP) was lower (< 2.9 mg/L) than the proposed cut-off for a healthy population (< 5.0 mg/L). Reference interval for fibrinogen was higher (1.9–4.4 g/L), than the available RIs (1.8–3.5 g/L). D-dimer cut-off value was set at 852 µg/L fibrinogen equivalent units (FEU), higher than the proposed 500 µg/L FEU for venous thromboembolism (VTE) exclusion.ConclusionsThe applicability of the available RIs for WBC count, PT, and APTT-ratio was confirmed. However, RIs for CRP and fibrinogen differed significantly than the available common national RIs for the healthy non-athletes’ population. A higher cut-off for D-dimers should be extensively verified before implementation for VTE diagnosis exclusion in a group of healthy young female athletes.
