Perspectives on good preceptorship: A matter of ethics.

Background: Clinical education is an essential part of the Bachelor's program in Nursing and a keystone of professional nursing education. Through clinical experiences, the student nurses acquire nursing knowledge and essential skills for professional practice. The preceptor plays a vital role in the development of student nurses becoming professional nurses.

Projected marine climate change: effects on copepod oxidative status and reproduction.

Zooplankton are an important link between primary producers and fish. Therefore, it is crucial to address their responses when predicting effects of climate change on pelagic ecosystems. For realistic community-level predictions, several biotic and abiotic climate-related variables should be examined in combination.

The enhancement of clinical competence through caring science.

This theoretical research attempts to create a new basis for dialogue between two independent research fields that are connected by an inseparable link. The first, nursing science, is a body of professional knowledge, while the second, caring as an independent body of pure knowledge, conducts basic research with an aspiration towards applicability. This theoretical research uses the guidelines of the Buberian dialogue, which provides new meaning to the concept of clinical competence.

Becoming a caring nurse--a Nordic study on students' learning and development in clinical education.

The aim of this study was to elucidate the meaning and deepen the understanding of student learning and development in becoming a nurse. Data were collected from focus group interviews with students from three different universities and analysed using a phenomenological-hermeneutical method. The comprehensive understanding of student learning and development in becoming a nurse resulted in two constituents: the prerequisites for learning and development, and itineraries for learning and development.

Zest for life among 65- and 75-year-olds in Northern Finland and Sweden--a cross-sectional study.

Background: Zest for life refers to being satisfied with life and having the energy and courage to look for new experiences. Research into zest for life among older people is scarce, even though it is an important topic. Similarly related concepts such as life satisfaction, quality of life and purpose in life have received more attention.

Relative importance of social status and physiological need in determining leadership in a social forager.

Group decisions on the timing of mutually exclusive activities pose a dilemma: monopolized decision-making by a single leader compromises the optimal timing of activities by the others, while independent decision-making by all group members undermines group coherence. Theory suggests that initiation of foraging should be determined by physiological demand in social foragers, thereby resolving the dilemma of group coordination. However, empirical support is scant, perhaps because intrinsic qualities predisposing individuals to leadership (social status, experience or personality), or their interactions with satiation level, have seldom been simultaneously considered.

The caregivers' possibilities of providing ethically good care for older people--a study on caregivers' ethical approach.

In the care of older people, unexpected and unpredictable situations often occur, which sometimes involve challenging ethical decision-making. This study starts off from an ethical perspective with caritative caring as the theoretical framework. The aim of this descriptive study is to describe what possibilities care givers regard themselves to have to provide good care based on ethical values in the daily care of older persons.

Assessment of ethical ideals and ethical manners in care of older people.

The aim of this study is to establish structured clusters and well-defined ontological entities (nodes) describing ethical values as both ideal and opportunity for ethical manner as perceived by thecaregiver.In this study, we use Bayesian Belief Networks (BBNs) to analyse ethical values (ethos) and ethical manners in daily work with older people. Material is based on questionnaire data collected by the instrument for the self-assessment of individual ethos in the care of older people(ISAEC) in spring 2007 in a municipality in Western Finland.

Brood size matching: a novel perspective on predator dilution.

A primary benefit of grouping is diluting the individual risk of attack by predators. However, the fact that groups are formed not always by solitary adults but also by subgroups (e.g.

Exploring the genetics of nestling personality traits in a wild passerine bird: testing the phenotypic gambit.

When several personality traits covary, they form a behavioral syndrome. Understanding the evolutionary dynamics of a behavioral syndrome requires knowledge of its genetic underpinning. At present, our understanding of the genetic basis of behavioral syndromes is largely restricted to domestic and laboratory animals.

Maternal effects may act as an adaptation mechanism for copepods facing pH and temperature changes.

Acidification of the seas, caused by increased dissolution of CO(2) into surface water, and global warming challenge the adaptation mechanisms of marine organisms. In boreal coastal environments, temperature and pH vary greatly seasonally, but sometimes also rapidly within hours due to upwelling events. We studied if copepod zooplankton living in a fluctuating environment are tolerant to climate change effects predicted for 2100, i.

Competitive exclusion within the predator community influences the distribution of a threatened prey species.

While much effort has been made to quantify how landscape composition influences the distribution of species, the possibility that geographical differences in species interactions might affect species distributions has received less attention. Investigating a predator-prey setting in a boreal forest ecosystem, we empirically show that large-scale differences in the predator community structure and small-scale competitive exclusion among predators affect the local distribution of a threatened forest specialist more than does landscape composition. Consequently, even though the landscape parameters affecting Siberian flying squirrel (Pteromys volans) distribution (prey) did not differ between nest sites of the predators Northern Goshawks (Accipiter gentilis) and Ural Owls (Strix uralensis), flying squirrels were heterospecifically attracted by goshawks in a region where both predator species were present.

Philopatric predisposition to predation-induced ecological traps: habitat-dependent mortality of breeding eiders.

Because population size is sensitive to changes in adult survival, adult survival may be buffered against environmental variability. Philopatry may be adaptive in changing environments, but it could also constrain breeding habitat selection under changing conditions such as shifting predation regimes. Habitat preference and quality could become decoupled in long-lived philopatric species that evolved in stable environments when suddenly faced by increased adult predation risk, as dispersal may be triggered by past reproductive failure.

Kin association during brood care in a facultatively social bird: active discrimination or by-product of partner choice and demography?

Intra-group relatedness does not necessarily imply kin selection, a leading explanation for social evolution. An overlooked mechanism for generating population genetic structure is variation in longevity and fecundity, referred to as individual quality, affecting kin structure and the potential for cooperation. Individual quality also affects choosiness in partner choice, a key process explaining cooperation through direct fitness benefits.

Patchiness and co-existence of indigenous and invasive mussels at small spatial scales: the interaction of facilitation and competition.

Ecological theory predicts that two species with similar requirements will fail to show long-term co-existence in situations where shared resources are limiting, especially at spatial scales that are small relative to the size of the organisms. Two species of intertidal mussels, the indigenous Perna perna and the invasive Mytilus galloprovincialis, form mixed beds on the south coast of South Africa in a situation that has been stable for several generations of these species, even though these populations are often limited by the availability of space. We examined the spatial structure of these species where they co-exist at small spatial scales in the absence of apparent environmental heterogeneity at two sites, testing: whether conspecific aggregation of mussels can occur (using spatial Monte-Carlo tests); the degree of patchiness (using Korcak B patchiness exponent), and whether there was a relationship between percent cover and patchiness.

The relevance of marine chemical ecology to plankton and ecosystem function: an emerging field.

Marine chemical ecology comprises the study of the production and interaction of bioactive molecules affecting organism behavior and function. Here we focus on bioactive compounds and interactions associated with phytoplankton, particularly bloom-forming diatoms, prymnesiophytes and dinoflagellates. Planktonic bioactive metabolites are structurally and functionally diverse and some may have multiple simultaneous functions including roles in chemical defense (antipredator, allelopathic and antibacterial compounds), and/or cell-to-cell signaling (e.

Nurses as patient advocates in oncology care: activities based on literature.

This article will explore oncology nurses' patient advocacy activities and compare those activities with patient advocacy activities defined in an earlier study by the authors. Data were collected from 42 English-language peer-reviewed articles published from 2000-2010. Search terms used included cancer care and advocacy and oncology nursing and advocacy.

Differential responses to related hosts by nesting and non-nesting parasites in a brood-parasitic duck.

Host-parasite relatedness may facilitate the evolution of conspecific brood parasitism, but empirical support for this contention remains inconclusive. One reason for this disparity may relate to the diversity of parasitic tactics, a key distinguishing feature being whether the parasite has a nest of her own. Previous work suggests that parasites without nests of their own may be of inferior phenotypic quality, but because of difficulties in identifying these parasitic individuals, little is known about their host selection criteria.

Advanced practice nurses' scope of practice: a qualitative study of advanced clinical competencies.

Aim: To describe and explore Advanced Practice Nurses' clinical competencies and how these are expressed in clinical practice.

Background: Discussion concerning advanced clinical practice has been ongoing in the USA since the 1960s and in the UK since the late 1980s. Approximately 24 countries, excluding the USA, have implemented the role of Advance Practice Nurse (APN).

Causes and consequences of fine-scale breeding dispersal in a female-philopatric species.

The potentially confounded effects of factors affecting breeding dispersal have rarely been simultaneously examined. The consequences of breeding dispersal are even less studied, presenting a paradox: breeding dispersal seldom seems to improve breeding success, despite its presumed adaptiveness. We studied the causes and consequences of breeding dispersal in female-philopatric eiders (Somateria mollissima) in relation to the spatiotemporal predictability of nest success.

Validity and reliability testing of the Oulu patient classification: instrument within primary health care for the older people.

Aim.  The aim of the study was to evaluate the reliability and validity of The Oulu Patient Classification (OPC) instrument to see whether the instrument that has been developed for hospital care is valid and useful within primary health care for older people. Background.

Adult predation risk drives shifts in parental care strategies: a long-term study.

1. Grouping provides antipredatory benefits, and therefore aggregation tendencies increase under heightened predation risk. In socially breeding groups, however, conflicts over reproductive shares or safety tend to disintegrate groups.

Do female ornaments indicate quality in eider ducks?

The fitness consequences of female ornamentation remain little studied and the results are often contradictory. Female ornamentation may be an artefact of a genetic correlation with male ornamentation, but this possibility can be disregarded if the ornament only occurs in females. Female-specific white wing bars in eiders (Somateria mollissima) have been suggested to indicate individual quality, and we studied size variation in this trait in relation to key fitness components and quality attributes.

Age-specific nest-site preference and success in eiders.

Variation in nest concealment is puzzling given the expected strong selection for safe nest sites. Selecting a concealed nest may decrease the risk of clutch predation but hinder parents from escaping predators, providing a possible solution to this paradox. Because the relative value of current versus future reproduction may vary with breeder age or state, nest concealment may also vary as a function of these attributes.

Oulu Patient Classification instrument within primary health care.

Unlabelled: As patients have become older their care needs have increased, and this has consequences for the working conditions within primary health care.

Objectives: The aim of this study was to evaluate, whether the OPC instrument, which has been developed for hospital care, is valid and useful within primary healthcare for older people.

Materials And Methods: Reliability and validity testing of the OPC instrument was carried out at a health care centre in Eastern Finland spring 2004.
