Trophic transfer of differently functionalized zinc oxide nanoparticles from crustaceans (Daphnia magna) to zebrafish (Danio rerio)
The potential uptake and trophic transfer of nanoparticles (NP) is not well understood so far and for ZnO NP the data presented in peer-reviewed literature is limited. In this paper the influence of surface functionalization on the uptake and depuration behavior of ZnO NP, ZnO-OH NP and ZnO-octyl NP in D. magna was studied. Bulk ZnO particles (≤ 5μm) and ZnCl2 were used as references for upt...


Population-level effects in Amphiascus tenuiremis: Contrasting matrix- and individual-based population models
Environmental risk assessment (ERA) is generally based on individual-level endpoints, even though protection goals in ERA intend higher biological levels. Population models have the potential to translate individual-level endpoints to population-level responses and range from simple demographic equations to highly complex individual based models (IBMs). The aims of the current study were to dev...
Lack of variation in voltage-gated sodium channels of common bottlenose dolphins (Tursiops truncatus) exposed to neurotoxic algal blooms
In coastal marine ecosystems, neurotoxins produced by harmful algal blooms (HABs) often result in large-scale mortality events of many marine species. Historical and frequent exposure to HABs therefore may provide a strong selective pressure for adaptations that result in toxin resistance. Neurotoxin resistance has independently evolved in a variety of terrestrial and marine species via mutatio...


Effects of nitrogen and phosphorus on arsenite accumulation, oxidation, and toxicity in Chlamydomonas reinhardtii
We studied arsenite (iAsIII) accumulation, oxidation, and toxicity in the freshwater green alga Chlamydomonas reinhardtii under nutrient-enriched (+NP), phosphorus-limited (-P), and nitrogen-limited (-N) conditions. The–P alga (55.1μM) had a Michaelis constant (K d) for uptake approximately one tenth of the +NP (419μM) and–N (501μM) cells, indicating iAsIII uptake inhibition by extracell...
Neurobiological correlates of depressive symptoms in people with subjective and mild cognitive impairment
To test the hypothesis that depressive symptoms correlate with Alzheimer's disease (AD) type changes in CSF and structural and functional imaging including hippocampus volume, cortical thickness, white matter lesions, Diffusion tensor imaging (DTI), and fluoro-deoxy-glucose positron emission tomography (FDG-PET) in patient with subjective (SCI) and mild (MCI) cognitive impairment. MethodIn 60 p...


Functional Assessment and Intervention by Nursing Assistants in Hospice and Palliative Care Inpatient Care Settings: A Quality Improvement Pilot Study
This study assessed the impact of a nursing assistant-led functional intervention in an urban hospice. Thirty-three patients participated. A physical therapist trained 4 nursing assistants to assess 4 basic functional activities at admission and discharge and to provide daily activity training to intervention group participants. Control group participants were assessed at admission and discharg...
Holistic support for micro-enterprise development: a case study of MITTRA
Micro-enterprise development (MED) has been recognised as an important strategy for employment generation and poverty alleviation in developing countries. Holistic approach (providing integrated services) is identified as an important approach to help poor in establishing their own enterprise. The present study is about critically analysing and assessing the workings of this approach. The major...

Types of governance, financial policy and the financial performance of micro-family-owned businesses in Canada
The purpose of this study is to examine the impact of type of governance on financial policy and financial performance of micro-family-owned businesses in Canada. This study utilised survey research (a non-experimental field study design). Micro-family-business owners from Western Canada were asked about their beliefs, perceptions and feelings regarding type of governance, financial policy and ...
Approaches to microenterprise development: comparison of case studies from Maharashtra
Among various self-employment options, the microenterprise has been recognised as an important tool for employment generation and poverty alleviation in developing countries by policy makers. This study looks at some selected approaches for promoting microenterprises. For the study, four organisations that have adopted various approaches for the promotion of microenterprises, namely, the buildi...

Enterprising behaviour in an integrating competence framework
We present insights from literature on enterprising behaviour and competence followed by an application of the competence perspective. Data collection is based on the critical incident technique among 205 entrepreneurs. The study shows how entrepreneurial behaviour benefits from an integrating competence perspective, underlining that entrepreneurs do need different competences related to differ...
A study of interrelationship between individual level change factors with individual and organisational level benefits, in the context of firms from an emerging economy
The purpose of this research is to establish the relationship between individual level change factors that transpires into individual and organisational benefits. Structured survey questionnaire was administered on managers and the data collected were analysed by exploratory factor analysis and structured equation modelling. Ten factors relating to individual level change and individual and org...

Internationalisation of film production: a historical review of movie making in Taiwan and Hong Kong
Three major approaches to explaining the motivations behind international film production are reviewed in this study: the creative/economic approach, the international business approach, and the historical approach. In addition, the case of international joint film productions between Taiwan and Hong Kong is examined to show that the process of internationalisation in the film industry is more ...
Role of knowledge management in promoting research and development in business organisations
Serendipity leads to discoveries and innovative knowledge. Mergers and acquisitions also make available knowledge, which can give new directions and impetus to the innovative R&D activities. Organisations dealing with the development of improved new products continuously use KM extensively for promoting their R&D work. In fact cross-national culture differences disappear in KM practices. Higher...
Homogenization of one-dimensional oscillatory systems with spatially modulated parameters
Oscillations of one-dimensional systems with spatially modulated parameters, in particular, strings with a varying cross section, are investigated. The method of direct separation of the motions is used, adapted to investigate systems in which separation of the variables is carried out in the spatial coordinate, rather than in time. It is established that modulation of the cross section of the ...
Impact of organic pollutants on metal and As uptake by helophyte species and consequences for constructed wetlands design and management
Various industrial processes and anthropogenic activities in urban areas induce a release of metals, metalloids and organic pollutants. Phytoremediation of co-contaminated waters in constructed wetlands is a promising solution for reducing the impact on natural environments. In order to improve the design and management of constructed wetlands, more knowledge is needed concerning the effect of ...
