Resolving problematic luminescence chronologies for carbonate- and evaporite-rich sediments spanning multiple humid periods in the Jubbah basin, Saudi Arabia

Most of the world's presently hyper-arid desert regions have experienced previous periods of significantly higher humidity and milder environmental conditions. The timing of these 'greening events' is critical to research upon global climatic fluctuations and for studies of hominin palaeodemography and range expansion, contraction, and extinction, but dating these climatic shifts via terrestrial sedimentary records can be difficult. Here, we outline the challenges inherent in the radiometric dating of carbonate- and evaporite-rich sediments preserved in the Jubbah basin (Nefud Desert, northern Saudi Arabia), a critical area for reconstructing the evolution of local hydrological regimes across long timescales. The Jubbah basin is surrounded by sandstone jebels (bedrock outcrops), which have prevented significant leeward dune accumulation for at least 400,000 years. The sedimentary sequences in the basin indicate repeated fluctuations between arid and humid climatic conditions, and provide key hydroclimatic rec…

Singapore as Science ’Scape and Ethnoscape

As a state project to locate the nation within the global knowledge economy, Singapore’s Technology Corridor has acted as a testbed for experimenting with different models of an international scientific community. Its landscape, from garden-style science parks modelled after Silicon Valley to monuments for multidisciplinary research such as One North, reflects the dynamic interaction among various political and ideological aspirations—ideoscapes—driving the built environment. Through both documentary research and semi-structured interviews of scientists and entrepreneurs, we examine how mostly foreign expat and some Singaporean researchers have experienced Singapore’s unique science ‘scape and adapted to a hybrid work and living environment. Testimony of the scientific sojourners of Singapore’s diverse ethnoscape—from China and India to Europe and the United States—reveal the blending of different styles of scientific work and the interconnected flows of intellectual labour.

From capacity to capability? : rethinking the prime agenda for inclusive development in management education

This paper assesses whether current recent developments in management education, particularly PRME (the United Nations Principles for Responsible Management Education), can contribute to the promulgation of an inclusive development that moves beyond the discourse of ‘growth’ and ‘income’. Based on an exploration of current literature on inclusive development, Amartya Sen’s capability approach, and the principles themselves, we argue that PRME in its current form reproduces a dominant market logic. It lacks the sensitivity to difference as captured in the plural quality of the capability approach. In response, we suggest a PRME agenda for management education that contributes to inclusive development as human wellbeing, rewriting it in terms of capabilities.

Assessment of long-term retention of environmental education lessons given to teachers in rural areas of Madagascar

Assessing the retention of knowledge is the first step of environmental education programs. The low education level in rural areas is one factor influencing habitat loss in Madagascar. We tested whether environmental education lessons given to teachers from a municipality, Iaboakoho, in a priority area for lemur conservation were retained after one year. Questionnaires were given to teachers from Iaboakoho and from other three neighbouring municipalities (control groups). Teachers from Iaboakoho had higher scores than the others. Knowledge gained was retained and might be transferred to children. Increasing proenvironmental attitudes and behaviours is the next step to reduce environmental exploitation.

Psychometric properties of the Beliefs about Medicine Questionnaire (BMQ)-AET for Women taking Adjuvant Endocrine Therapies (AET) following early-stage breast cancer

Objectives: To evaluate the Beliefs about Medicine Questionnaire to explore adherence to adjuvant endocrine therapy after treatment for breast cancer (BMQ-AET). Method: Factor structure of the BMQ-AET was explored alongside internal consistency, convergent validity and acceptability. Results: The BMQ-AET Specific Scale fitted the original 10 item model. Internal consistency of the BMQ-AET was much improved compared to the original BMQ and convergent validity showed predicted direction of correlation, although correlation with BMQ-AET concerns scale was low. Acceptability was good. Conclusions: The evaluation of the BMQAET is encouraging, and could facilitate future research around adherence to AET.

Impaired self-awareness following acquired brain injury

Impaired self-awareness of everyday task ability following acquired brain injury (ABI) presents a serious obstacle to progress in rehabilitation. However, there is a lack of consensus about the optimal method of determining awareness level, how best to increase awareness, and even with regard to the very nature of impaired awareness. Awareness level is usually ascertained by comparing self/third party ratings of task performance. A behavioural measure of task performance would circumvent some of the concerns regarding the validity of methods relying solely on verbal report. Three main research questions were identified: 1. Is it possible to measure self-awareness of activity limitation and impairment? 2. Is it possible to increase self-awareness of activity limitation and impairment? 3. What is the nature of impaired awareness of activity limitation and impairment? To address these questions, the research programme had four phases: In phase 1, a cross-sectional design was used, incorporating behavioural o…

Human occupation of the northern Arabian interior during early Marine Isotope Stage 3

The early part of Marine Isotope Stage (MIS) 3 (ca. 60–50 ka) is a crucial period for studying human demography and behaviour in south-west Asia, and how these relate to climatic changes. However, the archaeological and palaeoenvironmental records for MIS 3 in critical areas such as the Arabian Peninsula remain poorly developed. Here, we present findings from the Al Marrat basin in the Nefud desert, which provides the first clear evidence for both increased humidity and human occupation of the interior of northern Arabia during early MIS 3. A Middle Palaeolithic assemblage, dated by optically stimulated luminescence to ca. 55 ka, was found stratified within a sequence of relict palustrine deposits indicative of shallow water body formation in the Al Marrat basin. Hominin presence in northern Arabia at this time coincides with the intensification and northward displacement of monsoon rainfall systems during a period of maximum insolation. These findings add to a growing corpus of palaeoenvironmental evidence, …

Reaching consensus on reporting Patient and Public Involvement (PPI) in research: methods and lessons learned from the development of reporting guidelines

Introduction. Patient and Public Involvement (PPI) is inconsistently reported in health and social care research. Improving the quality of how PPI is reported is critical in developing a higher quality evidence base to gain a better insight into the methods and impact of PPI. This paper describes the methods used to develop and gain consensus on guidelines for reporting PPI in research studies (GRIPP2). Methods. There were three key stages in the development of GRIPP2: identification of key items for the guideline from systematic review evidence of the impact of PPI on health research and health services; a three phase online Delphi survey with a diverse sample of experts in PPI to gain consensus on included items; and a face to face consensus meeting to finalise and reach definitive agreement on GRIPP2. Challenges and lessons learnt during the development of the reporting guidelines are reported. Discussion. The process of reaching consensus is vital within the development of guidelines and policy direct…

Mapping socio-economic barriers to the implementation of energy efficiency policies in the UK building sector

In 2015 the UK building sector accounted for 43% (29% domestic, 14% commercial) of the national energy consumption, thereby positioning this sector as critical in meeting national energy efficiency targets. However, barriers to energy efficiency are vast and complex, and overcoming them is a key challenge for effective implementation of energy efficiency policies. This paper describes the findings from a review of literature and an expert survey to map and assess the key social, cultural, educational, economic and institutional barriers (in terms of small, medium and high impact) to implementing energy efficiency policies across the UK building sector. Overall the barriers are found to be strongly linked with consumer behaviour. They are often highly complex with multiple inter-relations. The barriers with the highest impact comprise the undervaluing of energy efficiency, lack of motivation and inertia within consumers/end users, infrastructural and planning barriers to medium sized energy projects as well a…
