A millennial record of environmental change in peat deposits from the Misten bog (East Belgium)

In this study, palaeoenvironmental changes recorded in the top metre of a peat profile (Misten bog, East Belgium) were investigated using a multiproxy approach. Proxies include bulk density, Ti and Si content, pollen, macrofossils, d13C on specific Sphagnum stems, and d13C–d18O on Sphagnum leaves. A high-resolution chronology was generated using 210Pb measurements and 22 14C AMS dates on carefully selected Sphagnum macrofossils. d13C only records large change in mire surface wetness. This is partly due to the fact that the core was taken from the edge of a hummock, which may make it difficult to track small isotopic changes. The d13C signal seems to be dependent upon the Sphagnum species composition. For example, a change between Sphagnum section Cuspidata towards Sphagnum imbricatum causes a significant drop in the d13C values. On the whole, the C and O isotopes record two shallow pool phases during the 8th–9th and the 13th centuries. Pollen and atmospheric soil dust (ASD) fluxes records increased human occupation in the area. There may be some climatic signals in the ASD flux, but they are difficult to decipher from the increasing human impact (land clearance, agriculture) during the last millennium. The variations in the proxies are not always synchronous, suggesting different triggering factors (temperature, wetness, windiness) for each proxy. This study also emphasizes that, compared to studies dealing with pollution using geochemical proxies, palaeoclimatic inferences from peat bogs need as many proxies as possible, together with highly accurate and precise age-models, in order to better understand climate variability and their consequences during the Holocene.

Interlocking directorates and conflicts of interest: The Rotterdamsche Bankvereeniging, Müller & Co. and the Dutch financial crisis of the 1920s

How can interlocking directorates cause financial instability for universal banks? A detailed history of the Rotterdamsche Bankvereeninging in the 1920s answers this question in a case study. This large commercial bank adopted a new German-style universal banking business model from the early 1910s, sharing directors with the firms it financed as a means of controlling its interests. Then, in 1924, it required assistance from the Dutch state in order to survive a bank run brought on by public concerns over its close ties with Müller & Co., a trading conglomerate that suffered badly in the economic downturn of the early 1920s. Using a new narrative history combined with an interpretive model, this article shows how the interlocking directorates between the bank and this major client, and in particular the direction of influence of these interlocks, resulted in a conflict of interest that could not be easily overcome.

International Projects and Cross-Cultural Adjustment of British Expatriates in Middle East: A Qualitative Investigation of Influencing Factors

Increased globalisation within the British AEC (Architectural, Engineering and Construction) sector has increased the need for companies to transfer staff to manage their overseas operations. To be able to perform abroad, expatriates must harmonise themselves to the conditions prevailing in the host country. These include getting accustomed to living, working and interacting with the host country nationals. The process is commonly referred to as 'cross-cultural adjustment'. Various factors influence the process of adjustment. In order to identify these issues, a qualitative study was undertaken, which mainly comprised of comprehensive literature review, individual interviews and focus group discussion with British expatriates working on international AEC assignments in Middle Eastern countries. Through interpretative approach, the current study aims to understand the concept of cross-cultural adjustment of British Expatriates based in Middle East and their influencing factors.

The findings suggest that success of expatriation does not entirely rest on an expatriate's ability but also on organisational support and assistance that expatriates receive prior to and during the assignment. Organisational factors such as selection mechanisms, job design, training, logistical and social support, mentoring, etc., influence various facets of expatriate adjustment. Striking cultural contrasts between British and Arab culture both in work and non work situations also dictate the level of support required by the expatriate, suggesting that relocation to less developed, remote or politically unstable regions, demands additional support and consideration by the parent company. This study is relevant to the AEC companies employing British expatriates, who need to be cognisant of the issues highlighted above to make rational and informed decisions when handling international assignments in the Middle East.

The influence of culture on home-based family caregiving at end-of-life: A case study of Dutch reformed family care givers in Ontario, Canada

Families are facing increased pressure to provide care to their terminally-ill or dying kin in the home. It is known that balancing care with other personal and social roles can adversely affect family caregivers' (FCGs) health, yet access to supportive services which can mitigate burden is often inadequate. Cultural factors are known to shape the experience of caregiving; however, most research to date tends to neglect the experiences of FCGs from different cultural groups. This understanding is necessary to ensure that supportive services are both meaningful and culturally-appropriate. Using qualitative methods, we undertook longitudinal research with a sample of Dutch Reformed FCGs (n = 5) to understand their experiences of caregiving and bereavement. The results of the study are suggestive of a cultural specificity with respect to caregiving that impacts both responsibilities and reactions to care. Three themes were salient to this group as a cultural entity: cultural attitudes towards care, religious beliefs and coping, and c. ulturally-informed care-seeking behaviours. These three themes were seen to be a function of their religious and ethnic identities and were reinforced by ties to the communities in which they resided. Cultural identity provided a framework through which to understand and make sense of the experience, while group membership provided access to networks of informal support. This research contributes to the geographical literature on care/caregiving by providing insight into the social, cultural and religious context of informal family caregiving with a population who live in close geographic proximity. On a practical level, this case study indicates the importance of considering how these factors may operate in other settings in order to implement timely and appropriate interventions to better support FCGs who are caring for their terminally-ill loved-ones at home.

An Update on Sedimentary Pigments in Victoria Land Lakes (East Antarctica)

Antarctic ice-free areas contain lakes and ponds that have interesting limnological features and are of wide global significance as early warning indicators of climatic and environmental change. However, most linmological and paleolimnological studies in continental Antarctica are limited to certain regions. There are several ice-free areas in Victoria Land that have not yet been studied well. There is therefore a need to extend limnological studies in space and time to understand how different geological and climatic features affect the composition and biological activity of freshwater communities. With the aim of contributing to a better limnological characterization of Victoria Land, this paper reports data on sedimentary pigments (used to identify the main algal taxa) obtained through a methodology that is more sensitive and selective than that of previous studies. Analyses were extended to 48 water bodies in ice-free areas with differing lithology, latitude, and altitude, and with different morphometry and physical, chemical, and biological characteristics in order to identify environmental factors affecting the distribution and composition of freshwater autotrophic communities. A wider knowledge of lakes in a limnologically important region of Antarctica was obtained. Cyanophyta was found to be the most important algal group, followed by Chlorophyta and Bacillariophyta, whereas latitude and altitude are the main factors affecting pigment distribution.

To compare the rejection rates of non-small cell lung cancer (NSCLC) samples obtained by differing sampling methods for testing by Sanger sequencing for epidermal growth factor receptor (EGFR) mutations. To assess the association between unsatisfactory outcomes and the quantity of DNA extracted from cytological versus histological samples.

Clinical and testing protocols for the analysis of epidermal growth factor receptor mutations in East Asian patients with non-small cell lung cancer:a combined clinical-molecular pathological approach

Several randomized phase III studies in advanced stage non-small cell lung cancer (NSCLC) confirmed the superior response rate and progression-free survival of using epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor as first-line therapy compared with chemotherapy in patients with activating EGFR mutations. Despite the need for EGFR mutation tests to guide first-line therapy in East Asian NSCLC, there are no current standard clinical and testing protocols.
