The determinants and consequences of adult nursing staff turnover: a systematic review of systematic reviews.

BACKGROUND: Nurses leaving their jobs and the profession are an issue of international concern, with supply-demand gaps for nurses reported to be widening. There is a large body of existing literature, much of which is already in review form. In order to advance the usefulness of the literature for nurse and human resource managers, we undertook an overview (review of systematic reviews). The aim of the overview was to identify high quality evidence of the determinants and consequences of turnover in adult nursing. METHODS: Reviews were identified which were published between 1990 and January 2015 in English using electronic databases (the Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, Applied Social Sciences Index and Abstracts, CINAHL plus and SCOPUS) and forward searching. All stages of the review were conducted in parallel by two reviewers. Reviews were quality appraised using the Assessment of Multiple Systematic Reviews and their findings narratively synthesised. RESULTS: Nine reviews were included. We found that the current evidence is incomplete and has a number of important limitations. However, a body of moderate quality review evidence does exist giving a picture of multiple determinants of turnover in adult nursing, with - at the individual level - nurse stress and dissatisfaction being important factors and -at the organisational level - managerial style and supervisory support factors holding most weight. The consequences of turnover are only described in economic terms, but are considered significant. CONCLUSIONS: In making a quality assessment of the review as well as considering the quality of the included primary studies and specificity in the outcomes they measure, the overview found that the evidence is not as definitive as previously presented from individual reviews. Further research is required, of rigorous research design, whether quantitative or qualitative, particularly against the outcome of actual turnover as opposed to intention to leave.

Impact of internet of things (IoT) in disaster management: a task-technology fit perspective

YesDisaster management aims to mitigate the potential damage from the disasters, ensure immediate and suitable assistance to the victims, and attain effective and rapid recovery. These objectives require a planned and effective rescue operation post such disasters. Different types of information about the impact of the disaster are, hence, required for planning an effective and immediate relief operation. The IoT technology available today is quite mature and has the potential to be very useful in disaster situations. This paper analyzes the requirements for planning rescue operation for such natural disasters and proposes an IoT based solution to cater the identified requirements. The proposed solution is further validated using the task-technology fit (TTF) approach for analyzing the significance of the adoption of IoT technology for disaster management. Results from the exploratory study established the core dimensions of the task requirements and the TTF constructs. Results from the confirmatory factor analysis using PLS path modelling, further, suggest that both task requirements and IoT technology have significant impact on the IoT TTF in the disaster management scenario. This paper makes significant contributions in the development of appropriate constructs for modeling TTF for IoT Technology in the context of disaster management

Dimensionality reduction methods for contingency tables with ordinal variables

Several extensions of correspondence analysis have been introduced in literature coping with the possible ordinal structure of the variables. They usually obtain a graphical representation of the interdependence between the rows and columns of a contingency table, by using several tools for the dimensionality reduction of the involved spaces. These tools are able to enrich the interpretation of the graphical planes, providing also additional information, with respect to the usual singular value decomposition. The main aim of this paper is to suggest an unified theoretical framework of several methods of correspondence analysis coping with ordinal variables

Intracorporeal versus extracorporeal anastomosis. Results from a multicentre comparative study on 512 right-sided colorectal cancers

Although nowadays considered as feasible and effective surgery in terms of short- and long-term results and oncological radicality, laparoscopic right colectomy is performed by a small number of surgeons, and in the vast majority of cases, this technique was performed with an extracorporeal anastomosis. Current literature failed to solve the controversies between intracorporeal and extracorporeal anastomosis after laparoscopic right colectomy

How does public service motivation affect teacher self-reported performance in an education system? Evidence from an empirical analysis in Italy

This paper deals with self-reported teacher performance, and the starting point is the relationship between teacher performance and the main determining factor, public service motivation. This relationship is complex because other relevant key factors, such as organizational citizenship behavior, job satisfaction, and person-organization fit come into play as mediation effects. In an Italian state school system, the authors propose modeling the public service motivation-individual performance process in order to identify the drivers that guarantee successful performance. In its analysis of these aspects, the study draws on data from a survey conducted among teachers working in Campania region in the south of Italy, resulting in a total of 507 valid questionnaires being obtained. In the proposed model, teacher performance is considered to be a consequence of the combined effects of public service motivation and other relevant key factors. The model was tested by using the Rasch models and structural equation modelling. The results of this study provide empirical evidence that teacher performance is, albeit indirectly, influenced by public service motivation
