Caring attributes and preparedness to care: effects of a pre-enrolled nursing certificate programme in Singapore

Background: Caring is a highly complex and abstract concept, and nurturing a caring attribute among individuals for a nursing career is believed to be best introduced at the start of student journey in preparatory courses specifically designed for nursing. However, because of the need to professionalise nursing, pre-enrolled nursing programmes have been discontinued and replaced by generic healthcare programmes in many parts of the world. Aim: This study aims to evaluate the impact of pre-enrolled certificate nursing education on students’ caring attributes and their preparedness to care. Methodology: A mixed methods approach using unstructured questions and the Caring Behaviour Inventory was employed to determine student caring attributes and their preparedness to care. The participants were final year pre-enrolled nursing students in Singapore. Findings: Students demonstrated attributes of caring based on an average CBI score of 4.55 (SD 0.32). Expressions of professional nurse caring were explicit in students’ entire learning journey and these took various forms of approach embedded in both curricular and extracurricular activites. The study also found that nurturing caring attributes was associated with a high expectation of student social behaviour and closely linked to the increasingly good reputation of nursing as a profession in that region. Conclusions: This study indicates the high potential value of pre-enrolled nursing education for developing the caring attributes of individuals. A nursing-oriented programme title and its high status associated with nursing were critical elements for nurturing the caring attributes. The implications for developments in nurse education and research are discussed

Embracing a culture in conducting research requires more than nurses' enthusiasm

Aims This study explored the perceptions of clinical nurses about their research knowledge and experiences to highlight any gaps in nurse education in supporting research activities in healthcare organisations. Background Nurses' research activities have been encouraged by moving hospital-based nurse education into higher education institutions whereby there is a stronger emphasis on teaching and developing nursing research at both undergraduate and post graduate levels. They were further encouraged by the introduction of advanced nurse practitioner roles, in the hope to increase opportunities for research participation. Whilst nurses' research activities have been explored in many countries, nurses in Singapore where there is a strong emphasis on evidence-based practice have not been investigated. Methods A mixed-methods exploratory descriptive design, using a questionnaire based on open and closed questions was employed to obtain the views of clinical nurses about their capacity and organisational support in conducting research. The questionnaires were distributed to convenient samples who attended one of the 4 research seminars held on separate occasions between July and August 2011 in Singapore. Results A total of 146 nurses were recruited. Whilst nurses demonstrated strong enthusiasm in conducting research, this characteristic feature was not adequate for them to embrace a research culture in organisations. Active participation as co-investigators was not possible in healthcare organisations where skewed distribution of resources towards medical and nurse researchers was perceived. Conclusions The results suggest a need for a significant shift in focus on educational training from imparting research contents to providing opportunities to experience the research process. Organisational support in terms of protected time and financial support ought to be in place for nursing research experience. The findings also demonstrated that in places where organisational support was available, awareness of research opportunities such as educational and organisational support needed to be strengthened. This in turn would enable more nurses particularly those who provide direct patient care to conduct research within the context of the competing nursing practice demands

Variable number of tandem repeat markers in the genome sequence of Mycosphaerella fijiensis, the causal agent of black leaf streak disease of banana (Musa spp)

ABSTRACT. We searched the genome of Mycosphaerella fijiensis for molecular markers that would allow population genetics analysis of this plant pathogen. M. fijiensis, the causal agent of banana leaf streak disease, also known as black Sigatoka, is the most devastating pathogen attacking bananas (Musa spp). Recently, the entire genome sequence of M. fijiensis became available. We screened this database for VNTR markers. Forty-two primer pairs were selected for validation, based on repeat type and length and the number of repeat units. Five VNTR markers showing multiple alleles were validated with a reference set of isolates from different parts of the world and a population from a banana plantation in Costa Rica. Polymorphism information content values varied from 0.6414 to 0.7544 for the reference set and from 0.0400 and 0.7373 for the population set. Eighty percent of the polymorphism information content values were above 0.60, indicating that the markers are highly informative. These markers allowed robust scoring of agarose gels and proved to be useful for variability and population genetics studies. In conclusion, the strategy we developed to identify and validate VNTR markers is an efficient means to incorporate markers that can be used for fungicide resistance management and to develop breeding strategies to control banana black leaf streak disease. This is the first report of VNTR-minisatellites from the M. fijiensis genome sequence. Key words: Molecular markers; VNTRs; Genetic diversity; Population genetics; Black Sigatok

Impact of open de-ionized water thin film laminar immersion on the liquid immersed ablation threshold and ablation rate of features machined by KrF excimer laser ablation of bisphenol A polycarbonate

Debris control and surface quality are potential major benefits of sample liquid immersion when laser micromachining; however, the use of an immersion technique potentially modifies the ablation mechanism when compared to an ambient air interaction. To investigate the machining characteristics, bisphenol A polycarbonate has been laser machined in air and under a controllable open liquid film. To provide quantitative analysis, ablation threshold, ablation rate and the attenuation coefficient of the immersing DI water fluid were measured. In ambient air the threshold fluence was measured to be 37 mJ.cm-2. Thin film immersion displayed two trends: threshold fluences of 58.6 mJcm-2 and 83.9 mJcm-2. The attenuation of DI water was found to be negligible; thus, the change in ablation rate resulted from increased confinement of the vapour plume by the liquid medium, generating higher Bremsstrahlung attenuation of the beam, lowering the laser etch rate. Simultaneously, splashing motivated by the confined ablation plume allowed release of plume pressure before plume etching commenced. This contributed to the loss of total etching efficiency. Two interaction scenarios were obsereved as a result of splashing: (i) intermediate threshold fluence, where splashing occured after every pulse in a mode that interrupted the flow entirely, leaving an ambient air interaction for the following pulse; (ii) high threshold fluence, where splashing occured for every pulse in a mode that allowed the flow to recommence over the image before the next pulse causing every pulse to experience Bremsstrahlung attenuation. Since attenuation of the immersion liquid was negligible, it is the action of the constrained ablation plume within a thin flowing immersion liquid, the resultant Bremsstrahlung attenuation and splashing events that are the critical mechanisms that modify the primary ablation characteristics

The Effect of Nitrided Layer on Antibacterial Properties for Biomedical Stainless Steel

AbstractPlasma nitriding of AISI type 303 austenitic stainless steel using microwave system at various input powers was conducted in present study. The nitrided layers were characterized via scanning electron microscopy, transmission electron microscopy and Vickers microhardness tester. The anti-bacterial property of this nitrided layer was also evaluated. The analytical results revealed the hardness of AISI type 303 stainless steel could be enhanced with nitriding process. The microstructure of the nitrided layer comprised of nitrogen-expanded γ phase. Bacterial test demonstrated the nitrided layer processed the excellent an ti-bacterial properties. The enhanced hardness and anti-bacterial properties make the nitrided AISI type 303 austenitic stainless steel the potential material in the biomedical applications

Algorithms as Folding: Reframing the Analytical Focus. 6(2): 1-12.

This article proposes an analytical approach to algorithms that stresses operations of folding. The aim of this approach is to broaden the common analytical focus on algorithms as biased and opaque black boxes, and to instead highlight the many relations that algorithms are interwoven with. Our proposed approach thus highlights how algorithms fold heterogeneous things: data, methods and objects with multiple ethical and political effects. We exemplify the utility of our approach by proposing three specific operations of folding—proximation, universalisation and normalisation. The article develops these three operations through four empirical vignettes, drawn from different settings that deal with algorithms in relation to AIDS, Zika and stock markets. In proposing this analytical approach, we wish to highlight the many different attachments and relations that algorithms enfold. The approach thus aims to produce accounts that highlight how algorithms dynamically combine and reconfigure different social and material heterogeneities as well as the ethical, normative and political consequences of these reconfigurations

On the stability of black hole event horizons

In this work we study a {\it gedanken} experiment constructed in order to test the cosmic censorship hypothesis and the second law of black hole thermo-dynamics. Matter with a negative gravitating energy is imagined added to a near extremal $U(1)$-charged static black hole in Einstein-Maxwell theory. The dynamics of a similar process is studied and the thermo-dynamical properties of the resulting black hole structure is discussed. A new mechanism which stabilizes black hole event horizons is shown to operate in such processes.Comment: 16, grammatical errors corrected and two references adde

Testing for heteroskedasticity of the residuals in fuzzy rule-based models

International audienceIn this paper, we propose a new diagnostic checking tool for fuzzy rule-based modelling of time series. Through the study of the residuals in the Lagrange Multiplier testing framework we devise a hypothesis test which allows us to determine if the residual time series is homoscedastic or not, that is, if it has the same variance throughout time. This is another important step towards a statistically sound modelling strategy for fuzzy rule-based models

Toy model for a two-dimensional accretion disk dominated by Poynting flux

We discuss the effect of the Poynting flow on the magnetically dominated thin accretion disk, which is simplified to a two-dimensional disk on the equatorial plane. It is shown in the relativistic formulation that the Poynting flux by the rotating magnetic field with Keplerian angular velocity can balance the energy and angular momentum conservation of a steady accretion flow.Comment: 17 pages, no figure
