Activity and Variety of Soil Microorganisms Depending on the Diversity of the Soil Tillage System

Soil is an ecosystem capable of producing the resources necessary for the development of the living organisms. Soil microorganisms (bacteria and fungi) are responsible for biomass decomposition, biogenic element circulation, which makes nutrients available to plants, biodegradation of impurities, and maintenance of soil structure. The presence of microorganisms in soil depends on their chemical composition, moisture, pH, and structure. Human activity has an indispensable influence on the formation of ecosystems. Soil tillage has an impact on the chemical and physical parameters of the soil, and thus on its biological properties. The use of inappropriate agro-technology can lead to degradation of the soil environment. Changes in soil properties may cause changes in soil abundance, activity, and diversity. Cultivation can affect microorganisms, causing their mortality and reducing the availability of nourishment in the soil. Therefore, it is extremely important to assess the diversity and microbiological activity of soil in relation to soil-tillage technology

Paternal Care in Collared Lemmings (Dicrostonyx richardsoni): Artifact or Adaptation?

Experiments conducted in large enclosures using 13 pairs of collared lemmings (Dicrostonyx richardsoni) and their pups examined the effects of three different treatments on paternal care. Treatments tested whether males altered their attentiveness to the pups when certainty of paternity was in question (through presence of a strange male), when alternative activities were available (through access to a running wheel), and when both factors were present simultaneously. Males covered and groomed pups equally among treatments. During the first five days of observation, males with access to a running wheel paid significantly less attention to strange males relative to males without access to a running wheel. Continuous exposure to the strange male may have been responsible for this short-term effect. Since covering and grooming of pups were unaffected by the presence of a strange male, the fathers' perceptions of their certainty of paternity were probably unaffected. Maintenance of paternal care under different conditions and in large enclosures provides further evidence that paternal care is not an artifact of laboratory conditions. Paternal care in collared lemmings may have evolved to maximize fitness of both sexes during winter.Key words: collared lemming, paternal care, winter breeding, fitnessDes expériences menées dans de grands enclos, et mettant en jeu 13 couples de lemmings à collerette (Dicrostonyx richardsonii) et leurs petits, évaluaient les effets de 3 traitements différents sur les soins paternels. Ces traitements vérifiaient si les mâles modifiaient l'attention qu'ils portaient à leurs petits lorsque leur paternité était mise en doute (par la présence d'un mâle étranger), lorsque d'autres activités étaient disponibles (par l'accès à une roue d'exercice), et lorsque ces 2 facteurs étaient présents en même temps. Les mâles protégeaient leurs petits et les nettoyaient de la même façon lors des différents traitements. Au cours des 5 premiers jours d'observation, les mâles qui avaient accès à une roue d'exercice prêtaient nettement moins attention aux mâles étrangers, comparativement aux mâles qui n'avaient pas accès à une roue. L'exposition continue au mâle étranger peut expliquer cet effet à court terme. Vu que les soins visant à protéger et à nettoyer les petits n'étaient pas affectés par la présence d'un mâle étranger, la perception qu'avaient les pères quant à la certitude de leur paternité n'était probablement pas affectée. Le maintien des soins paternels dans différentes conditions et à l'intérieur de grands enclos offre une preuve supplémentaire à l'appui que ces soins ne sont pas créés par les conditions de laboratoire. Les soins paternels chez le lemming à collerette ont peut-être évolué afin de maximiser la santé physique des 2 sexes en période hivernale.Mots clés : lemming à collerette, soins paternels, reproduction hivernale, santé physiqu

Factors affecting Polish nurses’ willingness to recommend the hospital as a place of care

Background: Nurses constitute the major professional group offering constant hospital patients’ care. Willingness to recommend their hospital reflects confidence in the offered care, satisfaction and identification with the work place. The aim of the present study has been to investigate which elements of hospital environment and nurse personal related factors predict recommendation of the hospital as a place of care by employed nurses. Material and Methods: Cross-sectional, correlation study was, based on 1723 self-reported, anonymous questionnaires of nurses working in 30 acute hospitals. Data was analyzed using the logistic regression model, with general estimation equations. Results: About 25% of nurses were unwilling to recommend their hospital as the place of care. The odds ratio (OR) of the lack of willingness to recommend the hospital was related to assessment of patients’ safety (OR = 0.28, 95% confidence interval (CI): 0.18–0.46, p = 0.00), decrease in the quality of patient care during the preceding year (OR = 0.62, 95% CI: 0.41–0.93, p = 0.02), overall work conditions (OR = 0.35, 95% CI: 0.22–0.57, p = 0.00), weak cooperation between nurses and physicians (OR = 0.37, 95% CI: 0.25–0.54, p = 0.00), poor work schedule flexibility (OR = 0.74, 95% CI: 0.55– 0.99, p = 0.04) and educational opportunities (OR = 0.71, 95% CI: 0.54–0.95, p = 0.02) and the level of nurses depersonalization (OR = 1.78, 95% CI: 1.18–1.68, p = 0.00). Conclusions: The hospital manager should consider strategies which improve patients’ safety and the staff working conditions. Thanks to that they will also achieve better and more competitive image of the hospital in the local community. Med Pr 2016;67(4):447–45

Factors influencing recommendation of a hospital as place of employment in the opinion of nurses working in Polish hospitals

Introduction. European states observe an increased demand for healthcare services and diminishing numbers of nurses working in the healthcare system. A divergence that may result in future shortages of hospital nursing staff. Aim. Definition of factors that influence readiness to recommend the hospital as place of employment by nurses employed in Polish hospitals. Material and method. Polish part of the RN4CAST protocol, the study uses logistic regression model on data from 2605 questioners from nurses working in 30 Polish hospitals. Results. About half of the responders declared readiness to recommend employment in their hospital. The recommendation depended on working conditions, quality of care, patient safety, and manager interest in professional development of personnel. Higher level of emotional burnout reduced the probability of recommendation. Conclusions. Working conditions, quality of care, patient safety, and potential of professional development are the main factors deciding about the eagerness to recommend employment in one’s hospital

Wpływ struktury zatrudnienia personelu i wybranych czynników organizacyjnych szpitala na wskaźnik zgonów pacjentów hospitalizowanych w szpitalach polskich uczestniczących w projekcie RN4CAST

Influence of hospital staffing and selected organisational circumstances on the death rate of patients treated in Polish hospitals participating in the RN4CAST project. Introduction. Adequate hospital staff employment and assorted organisational circumstances influence outcomes of hospitalised patients. Aim. To analyse influence of hospital staff employment structure and selected organisational circumstances on the death rate of patients hospitalised in acute hospitals. Material and method. Anonymous data of hospitalised patients (fragment of the NHF* report) and of hospital organisational questionnaire were used. The hospital death rate (proportion of hospital deaths to patient admissions) was defined as the dependent variable. The study included 25 hospitals, which provided all the required data. Statistical analysis was conducted in IBM SPSS Statistics 20, using rho Spearman’s rank correlation coefficient for quantitative variables and eta correlation ratio for qualitative variables. Results. The death rate value was adversely correlated with the number of employed physicians, nurses and other not-nursing staff who provided direct patient care. The global number of hospital intensive care units and allocation of separate medical and surgical intensive care units positively influenced the hospital death rate. Conclusions. The number of employed personnel (physician, nurses, and other staff) involved in direct patient care and organization of intensive care in a hospital structure influence the death rate of patients treated in Polish acute hospitals

Obciążenie pracą podczas ostatniego dyżuru w opiniach pielęgniarek pracujących w szpitalach objętych projektem RN4CAST

Workload during the last shift in the opinion of hospital nurses involved in RN4CAST projectBackground The issue of workload is one of the most important ones as far as the nurses’ profession is concerned. Numerous analyses prove the relationship between excessive workload and job dissatisfaction, which may lead to low morale, absenteeism, high rotation and low work efficiency and, consequently, result in deterioration of the care provided to the patient and even put the patient’s safety at risk. RN4CAST project is aimed at the evaluation of the workload which the nurses are exposed to during their shifts. Such a survey focuses on all structural determinants of hospital workload depending on: type of the ward, professional role, number of patients and their health condition as well as work conditions and organization: the number of working hours and shift staffing.Aim of the survey The survey is aimed at determining the factors responsible for the workload which the nurses are exposed to during their shifts in hospitals involved in RN4CAST project.Material and Methods The study included 2605 nurses working in 30 acute hospitals in Poland. The respondents were mainly women. Men made up only 0.4% of the population examined. The average age was 40.3 (SD = 7.8 years old). 23.5% of the respondents had the Bachelor’s degree in nursing. The average seniority was 18.6 years (SD = 8,6), and the seniority in the hospital involved in the survey – 15.6 years (SD = 9,2). The material was collected by means of a survey and a structurised questionnaire completed by the nurses on their own. A correlational model was used to evaluate the workload determinants.Results During their last shift 84% of the nurses worked, on average, 11.3 hours (SD = 2.4). The number of patients on the ward was 31.1, on average (SD = 12.6) it varied significantly (p = 0.000) depending on the ward type. The nursing care was provided by 3.4 qualified nurses on average (SD = 2.2). One nurse was responsible for 20.4 patients on average (SD = 11.1), [median = 18, first quartile (Q1) = 12, third quartile (Q3) = 29)]. It was proved that the increase in the total number of the patients on the ward was accompanied by the increase in the number of patients who required assistance with everyday routines (tau-b = 0.17; p = 0.000) and in the number of patients who required monitoring or hourly (or even more frequent) treatment (tau-b=0.37; p=0.000). Close examination of the variables responsible for individual workload showed that there is a little but noticeable correlation between the increase of the total number of patients on the ward (tau-b = 0.28; p = 0.000) and the increase in the number of patients each nurses was directly responsible for on her shift. There was a positive correlation (tau-b = 0.40; p = 0.000) between the total number of patients and the total number of qualified nurses providing direct care to these patients during their shifts. Also a slight negative correlation was observed (tau-b = –0.061; p = 0.000) between the total number of nurses and the number of patients each nurse was directly responsible for. There was also a slight positive correlation (tau-b = 0.18; p = 0.000) between the number of nurses and the number of helping staff who provided direct care to the patients during their shifts. And also a slight correlation was observed (tau-b = 0.061; p = 0.000) between the number of patients and the number of helping staff during the shifts. The analysis of the findings from both wards leads to the conclusion that the seven most frequent and common routines, which did not require nursing qualifications constituted a significant workload for nurses on all shifts (p = 0,000) and that the nurses who solely provided care to the patients were significantly more often responsible for routines which did not require any professional skills. The nurses examined, evaluated their hospital working conditions as poor – 28.9%; satisfactory – 46.8%; good – 23.2%; excellent – 1.1%. Majority of nurses (59.3%) claim that the number of hospital staff is definitely too low to work efficiently; 64.5% pointed out the lack of qualified nurses and 31.7% the lack of technical and helping staff. Vast majority of nurses (64%) claim that they can rely on the hospital management support only in some situations. Most nurses (77%) complained that their relations with the doctors were not always good, whereas 13.6% complained about lack of good professional relations between nurses and doctors.Conclusions 1. The analysis of the findings shows that structural factors (such as type of the ward, professional role, number and condition of patients) as well as organisational factors (such as number of shift hours, shift staffing and work environment) determined the nurses’ workload. 2. The shift survey as a device for evaluating nurses’ workload should be recommended to ward nurses and hospital management because of the simplicity with which particular elements can be observed. The observation can be carried out during a relatively short period of time (8–12-hour shift), which allows for a better and faster explanation of the reasons of excessive workload and consequently may lead to implementing solutions, which would eliminate this negative phenomeno
