Development and Testing of an Instrument for Summative Assessment of Practical Skill Performance: A Generalizability Theory Approach.

Background And Purpose: Many newly graduated nurses lack proficiency in practical skill performance. Presently, nursing students' practical skill is assessed by summative instruments with overarching items. The purpose of this study was to develop a more detailed instrument to use in summative assessment of nursing students' practical skill performance and to assess its psychometric properties.

Improving Clinical Nurses' Development of Supervision Skills through an Action Learning Approach.

The aim of this study was to investigate action learning as an implementation method in a large-scale project with many participants in several autonomous and geographically spread groups. The focus of the implementation was the Model of Practical Skill Performance as a learning and supervision tool in the clinical education of nursing students. Nineteen action learning groups were established, and a total of 129 clinical supervisors and 13 facilitators were involved.

The art of preceptorship. A qualitative study.

In the clinical nursing practice preceptorship is a widespread method to improve patient care by assisting nurses in developing the right clinical skills. However, little is known about how preceptorship should be practiced to achieve a positive learning outcome. The aim of the study was to investigate how preceptorship can be used in clinical practice to create learning and facilitate competence development.

Experiences and management of fatigue in everyday life among adult patients living with heart failure: a systematic review of qualitative evidence.

Background: Fatigue, a common and distressing symptom of heart failure, is a non-specific, invisible and subjective experience, which is difficult to describe and for which there are no effective interventions. Fatigue negatively impacts on patients' everyday life, prognosis and quality of life, therefore it is important that patients can manage, monitor and respond to changes in fatigue. To cope with fatigue patients may need or seek advice on self-management strategies.

From theoretical model to practical use: an example of knowledge translation.

Aim: To present a case of knowledge translation in nursing education and practice and discusses mechanisms relevant to bringing knowledge into action.

Background: The process of knowledge translation aspires to close the gap between theory and practice. Knowledge translation is a cyclic process involving both the creation and application of knowledge in several phases.

Model of practical skill performance as an instrument for supervision and formative assessment.

There are still weaknesses in the practical skills of newly graduated nurses. There is also an escalating pressure on existing clinical placements due to increasing student numbers and structural changes in health services. Innovative educational practices and the use of tools that might support learning are sparsely researched in the field of clinical education for nursing students.

Metal uptake in a peri-urban Lactuca sativa cultivated area.

In this study, two Lactuca sativa crops grown in a net-protected site and an unprotected site were compared. The results showed metals were accumulated by Lactuca sativa. Higher metal accumulation in lettuce grown in the unprotected parcel was established, and the only significant differences in their physicochemical properties were cation exchange capacity and exposure to sunlight.

Metal distribution in coral reef complex Cayo Arcas in the Gulf of Mexico.

This study evaluated the spatial and temporal distribution of metals in the coral reef system Cayos Arcas and Triangulos in the Campeche Bank region, off the Yucatan peninsula in Mexico. No information has been generated before for the incorporation of natural and non-natural occurring metals, some of which are possibly endowed by the oil marine station Cayo Arcas. The multivariate exploratory study of the metals on the coral skeletons, showed the formation of two distinct groups.

Assesment of trace elements and organic pollutants from a marine oil complex into the coral reef system of Cayo Arcas, Mexico.

Possible contaminants produced by the Petroleos Mexicanos (PEMEX) marine oil complex in the vicinity of the Cayo Arcas (Mexico) coral reef ecosystem were evaluated by analyzing sediments and sea water for hydrocarbons and metal elements. We found that the concentrations of aliphatic hydrocarbons in the sea water were generally low, with the highest values detected near the oil station; the concentration of polycyclic aromatic hydrocarbons (PAHs) was generally below the detection limit. The hydrocarbons found in the sediments seem to have a pyrogenic origin, and were probably produced by marine traffic in the study area.

Suitability of the vegetation types in Mexico's Tamaulipas state for the siting of hazardous waste treatment plants.

A land suitability study was carried out by applying a multiple-criteria technique to 12 different vegetation types in Mexico's Tamaulipas state to help select potentially suitable sites for hazardous waste treatment plants. Species richness, spatial distribution, and uniqueness were selected as the criteria for estimating a vegetation type's suitability. Using the analytical hierarchy process, we ranked and mapped vegetation types, then compared the results with rankings of the same vegetation types based only on their number of endemic species.

The influence of water-soluble As(III) and As(V) on dehydrogenase activity in soils affected by mine tailings.

Dehydrogenase activity (DHA) in soils contaminated by arsenic-bearing tailings was correlated with total arsenic and total water-soluble arsenic (As(III)+As(V)) to evaluate the impact of tailings dispersion on the oxidative capacity of soil microorganisms. Georeferenced surface soil samples (0-10 cm depth) were collected at different distances from a tailings dam. In the samples farthest from the dam, all water-soluble arsenic (avg.
