Modelling daylight for preserving identity : simulation of daylight levels for successful intervention in historic buildings

Historical listed buildings have their own unique cultural identity, which is one of the criteria used by decision mechanisms for their statutory protection. The identity of many of these buildings is often related to their tangible features/components, such as period characteristics (geometry, size, colour, form, and shape), materials and construction. Daylight is one of the in/tangible elements that have contributed to the distinctiveness of many historical buildings, yet when constructing preservation schemes of historical buildings, daylight is rarely introduced or considered as one of the components that shape the character of buildings. One of the reasons is the limited number of credible simulation studies that identify such interrelationships. As many of these buildings were originally designed to accommodate different activities to today's requirements, maintaining the quality of daylight that originally contributed to their visual identity can be a very challenging task, especially if the building is to be adapted to accommodate a different activity. In this paper we will discuss the conflict between maintaining the original visual identity of historical buildings and meeting the visual requirements of restored buildings. The paper discusses the visual performance of a traditional bathhouse (Hammam) in the city of Bursa in Turkey. The change in the visual performance of the selected case study will be discussed in terms of daylight conditions. The paper explores the possibility of maintaining the original daylight conditions of renovated historical buildings while meeting the visual requirements of the new use.

Efficient escrow-free identity-based signature

The notion of identity-based signature scheme (IBS) has been proven useful in some scenarios where relying on the validity of the certificates is impractical. Nevertheless, one remaining inherent problem that hinders the adoption of this cryptographic primitive in practice is due to the key escrow problem, where the private key generator (PKG) can always impersonate the user in the system. In 2010, Yuen et al. proposed the notion of IBS that does not suffer from the key escrow problem. Nevertheless, their approach relies on the judge who will later blame the malicious PKG when such a dispute occurs, assuming that the PKG is willing to collaborate. Although the approach is attractive, but unfortunately it is impractical since the malicious PKG may just refuse to collaborate when such an incident happens. In this paper, we propose a new escrow-free IBS, which enjoys three main advantages, namely key escrow free, practical and very efficient. We present a generic intuition as well as an efficient instantiation. In our approach, there is no judge involvement required, as the public can determine the malicious behaviour of PKG when such an incident happens. Further, the signature size of our instantiation is only two group elements, which outperforms the existing constructions in the literature.

The construction of a subset of ICNP® for patients with dementia: a Delphi consensus and a group interview study

BACKGROUND: The International Classification for Nursing Practice (ICNP®) 2013 includes over 4000 concepts for global nursing diagnoses, outcomes and interventions and is a large and complex set of standardised nursing concepts and expressions. Nurses may use subsets from the ICNP as concepts and expressions for research, education and clinical practice. The objective of this study was to identify and validate concepts for an ICNP subset to guide observations and documentation of nursing care for patients with dementia.

METHOD: The process model for developing ICNP subsets was followed, according to the guidelines adopted by the International Council of Nursing (ICN). To identify relevant and useful concepts for the subset, a modified form of the Delphi method was used. Six nurses working in healthcare services in three municipalities in Norway with postgraduate education in geriatric psychiatry and dementia care participated in two Delphi sessions. The participants reviewed and scored the concepts included in the suggested subset and had an opportunity to rewrite them and offer alternatives. To validate the subset after the Delphi study, a group interview was conducted with six other nurses with postgraduate education in geriatric psychiatry and dementia care. The group interview was recorded and transcribed, and summative content analysis was used.

RESULTS: Suitable concepts for an ICNP subset to guide observations and documentation of nursing care for patients with dementia were identified. In total, 301 concepts were identified, including 77 nursing diagnoses, 78 outcomes and 146 nursing interventions. An increased focus on concepts to describe basic psychosocial needs such as identity, comfort, connection, inclusion and engagement was recommended by nurses in the validation process.

CONCLUSIONS: Relevant and pre-formulated nursing diagnoses, goals and interventions were identified, which can be used to develop care plans and facilitate accuracy in the documentation of individuals with dementia. The participants believed that it may be difficult to find formulations for all steps of the nursing process. In particular, nursing diagnoses and psychosocial needs are often inadequately documented. The participants highlighted the need for the subset to contain essential information about psychosocial needs and communication.

Sexual orientation and gender-identity in high functioning individuals with autism spectrum disorder.

When compared to typically-developing individuals, individuals with Autism Spectrum Disorder(ASD) demonstrated significantly higher sexual diversity, with higher rates of non-heterosexuality, and reported more gender non-conforming identities. The ASD group reported poorer mental health than typically-developing individuals and belonging to a sexual or gender-diverse group worsened this effect.
