European phenological response to climate change matches the warming pattern

GLOBAL CHANGE BIOLOGY, Issue 10 2006
ANNETTE MENZEL
Abstract Global climate change impacts can already be tracked in many physical and biological systems; in particular, terrestrial ecosystems provide a consistent picture of observed changes. One of the preferred indicators is phenology, the science of natural recurring events, as their recorded dates provide a high-temporal resolution of ongoing changes. Thus, numerous analyses have demonstrated an earlier onset of spring events for mid and higher latitudes and a lengthening of the growing season. However, published single-site or single-species studies are particularly open to suspicion of being biased towards predominantly reporting climate change-induced impacts. No comprehensive study or meta-analysis has so far examined the possible lack of evidence for changes or shifts at sites where no temperature change is observed. We used an enormous systematic phenological network data set of more than 125 000 observational series of 542 plant and 19 animal species in 21 European countries (1971,2000). Our results showed that 78% of all leafing, flowering and fruiting records advanced (30% significantly) and only 3% were significantly delayed, whereas the signal of leaf colouring/fall is ambiguous. We conclude that previously published results of phenological changes were not biased by reporting or publication predisposition: the average advance of spring/summer was 2.5 days decade,1 in Europe. Our analysis of 254 mean national time series undoubtedly demonstrates that species' phenology is responsive to temperature of the preceding months (mean advance of spring/summer by 2.5 days°C,1, delay of leaf colouring and fall by 1.0 day°C,1). The pattern of observed change in spring efficiently matches measured national warming across 19 European countries (correlation coefficient r=,0.69, P<0.001). [source]


Subject and informant characteristics influence the reliability and validity of family history information: an analysis based on the generalized estimating equations approach

Abstract Family history information is a necessary surrogate for unavailable interview information in family studies. However, the reliability and validity of such information has rarely been assessed during the conduct of family studies. This paper presents a reanalysis of data on the reliability and validity of family history information for dementia and depression using the general estimation equations approach. All available relatives of patients and controls were interviewed and questioned about the psychiatric morbidity of other family members. Interinformant reliability of this family history information was evaluated as well as factors influencing this information. The validity of family history was investigated by comparing the informant derived diagnoses with interview-derived diagnoses. To account for possible lack of independence of family history provided by several family members on other family members, the generalized estimating equations (GEE) were used in statistical analysis. The interinformant reliability for depression (kappa = 0.13) was low. It was fair for dementia (kappa = 0.34). The informants more frequently agreed about the diagnosis of dementia when the subject was older. The sensitivity of family history was 35.2% for dementia and 31.8% for depression. The specificity of family history information was generally above 97%. The sensitivity of family history increased significantly with the severity of both disorders. The sensitivity of the family history for dementia was higher when the informant was a first-degree relative, when he was younger and when the index subject of the family suffered from dementia. The specificity of the family history was slightly reduced with higher age. The observed low sensitivity of family history information leads to underestimation of psychiatric disorders. The informants provide more useful information on more severe disorders. The sensitivity of family history was higher in families with an affected index subject than in control families, so familial aggregation of dementia might be overestimated in studies using the family history method.

People with intellectual disability as neighbours: Towards understanding the mundane aspects of social integration

JOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 5 2010
Laura M. van Alphen
Abstract Although people with intellectual disabilities (ID) are increasingly expected to relocate from traditional institutional care to ,regular' neighbourhood housing facilities and socially integrate in these neighbourhoods, little is known about how they are perceived and appreciated as neighbours. This paper reports on interviews carried out with 30 neighbours without ID who were neighbours of small-scale care facilities for people with ID. Interviews addressed the neighbours' everyday experiences of neighbouring in general, and neighbouring people with ID in particular. Neighbouring, for these informants, called for a fine balance between friendliness without over-involvement. While they were generally positive about their interactions with their neighbours with ID, it emerged that the formal nature of the care facility and the interaction style of some of the neighbours with ID often contravened informants' assumptions about neighbouring. Informants expressed concern about a possible lack of appropriate distance, reciprocity and accountability among their neighbours with ID. The nature of the care facility, with paid staff, often group activities, formal means of achieving the everyday small tasks which neighbours sometimes do for each other, and a high turnover of residents, all undermined the possibility of a typical neighbourly relationship. In conclusion, we suggest that integration of people with ID into everyday neighbouring relationships raises complex challenges for care organizations that need to find a balance between supporting the needs of people with ID they care for, adequate support and mediation for other neighbours when necessary, and all the while avoid becoming overly involved in neighbouring as a formal partner.

Communication effectiveness of nurses working in a variety of settings within one large university teaching hospital in western Japan

NURSING & HEALTH SCIENCES, Issue 4 2002
Misae Ito RN
Abstract This survey study measured the communication effectiveness of 176 nurses working on a variety of clinical units within one large university hospital in western Japan. The vast majority of the nurses demonstrated fair effectiveness in their communication skills. Although some of the nurses did demonstrate slightly higher communication effectiveness scores, few of the nurses' demographic characteristics appeared to influence how well they communicated. The major limitations of the present study were the use of one hospital for data gathering, and the possible lack of cultural sensitivity of the communication questionnaire. [source]
