Abstract:

We assessed ten trophodynamic indicators of ecosystem status for their sensitivity and specificity to fishing management using a size-resolved multispecies fish community model. The responses of indicators to fishing depended on effort and the size selectivity (sigmoid or Gaussian) of fishing mortality. The highest specificity against sigmoid (trawl-like) size selection was seen from inverse fishing pressure and the large fish indicator, but for Gaussian size selection, the large species indicator was most specific. Biomass, mean trophic level of the community and of the catch, and fishing in balance had the lowest specificity against both size selectivities. Length-based indicators weighted by biomass, rather than abundance, were more sensitive and specific to fishing pressure. Most indicators showed a greater response to sigmoid than Gaussian size selection. Indicators were generally more sensitive at low levels of effort because of nonlinear sensitivity in trophic cascades to fishing mortality. No single indicator emerged as superior in all respects, so given available data, multiple complementary indicators are recommended for community monitoring in the ecosystem approach to fisheries management.

Abstract:

The sizes of individual organisms, rather than their taxonomy, are used to inform management and conservation in some aquatic ecosystems. The European Science Foundation Research Network, SIZEMIC, facilitates integration of such approaches with the more taxonomic approaches used in terrestrial ecology. During its 4-year tenure, the Network is bringing together researchers from disciplines including theorists, empiricists, government employees, and practitioners, via a series of meetings, working groups and research visits. The research conducted suggests that organismal size, with a generous helping of taxonomy, provides the most probable route to universal indicators of ecological status.

Abstract:

The sensitivity of size-based, species-based, and trophodynamic indicators is examined for the fish community of the southern Benguela ecosystem (South Africa) through simulations of different fishing scenarios using the multispecies model OSMOSE. The simulations suggest that it may be erroneous to consider one absolute reference direction of change for any indicator because the direction of change is specific to both the multispecies assemblage and the fishing scenario considered. The analysis of species versus community indicators is helpful for understanding which processes drive the emergent properties of the ecosystem. Informative about the structure and state of the ecosystem, both types of indicators weighted by biomass or by abundance should be used to evaluate ecosystem changes. Indicators characterizing size distribution (e.g., slope of size spectrum) appear to be more helpful in distinguishing the cause of ecosystem changes than mean community indicators because their response is specific to the fishing scenario simulated (i.e., global or hake-targeting fishing). Some indicators do not seem to be sensitive to fishing pressure (slope of the diversity size spectrum) or do not vary consistently with other studies (W statistic).

Abstract:

This paper attempts to fill a research gap of literature by constructing the dynamic model into which both ex ante and ex post patent value indicators are incorporated. A patent renewal model is tested using a large set of Pharmaceutical patents granted by the European Patent Office between 1996 and 2009. We test five ex ante indicators and single ex post indicator including family size, patent backward citations, backward references to non-patent literature, number of claims, number of inventors, renewal fee, patent age, application year, and the ex post indicator forward citations. Empirical findings show that three citation related indicators, family size, and the number of claims are positively associated with patent values, while the number of inventors, renewal fee, patent age, and application year are negatively correlated. In addition, forward citations seem to have persistent learning effects on patent values.

Abstract:

The use of fish community indicators based on size spectra has become popular in the development of an ecosystem approach to fisheries. Size spectrum theory arose from basic ecological work on energy flow, predatorprey interactions, and biomass standing stock and was later applied to fish communities as lengthfrequency analysis. A multitude of size spectrum indicators have resulted, but it is not clear if they all present similar information. Here we develop a simple framework describing what four size spectra indicators suggest about fish communities, their likely response to fisheries exploitation, their ecological interpretation, and some of their biases. We examined indicators for scientific survey data from six exploited North Atlantic fish communities for the information that they reveal about each community. Each indicator revealed different information and had different biases. Combining indicators for the most impacted system (owing to fisheries and environmental change), the eastern Scotian Shelf, revealed a pattern analogous to Holling's ecological cycle of exploitation, conservation, release, and reorganisation. If this analogy is generally valid, then it suggests that collapsed fish communities are more susceptible to chance events, and recovery is not directly reversible and may not be recoverable (to previous known state) at all if the system moves to an alternative cycle.

Abstract:

This research aimed to analyze the performance of a bakery located in Bekasi from the customer satisfaction on product and service quality. The method applied was Importance-Performance Analysis (IPA). IPA was conducted to determine the status of indicators related to product and service quality. It was to provide input to management in taking strategic actions. The sample size was 127 respondents. The used technique was non probability sampling. The results reveal that the priority of improvement is the taste indicator for product quality. On the other side, courtesy indicator is the priority for service quality that occupies position in Quadrant A. Hence, the bakery should emphasize those indicators as improvement priorities.

Abstract:

This paper deals with the investigation of the relationship between firm size and firm in the Czech Republic during 2007–2012. The study aims to examine to what extent the confirmation or rejection of Gibrat’s law depends on the indicator of firm size. For measuring firm size we use three indicators: revenues, number of employees and total assets. The study uses data collected from the database Albertina CZ Gold Edition. Final dataset includes the data about more than 35,000 firms. The validity of Gibrat’s law was tested with the help of linear regression model with first-order autoregressive process. Gibrat’s law is rejected for all three indicators of firm size. Hence, the selected indicator of firm size is not proved to be important factor in verification of Gibrat’s law validity. It is also found out that the small firms in profit industries (A-N according to CZ-NACE classification) grow faster than their larger counterparts in the Czech Republic.

Abstract Dell, J. T. and Hobday, A. J. 2008. School-based indicators of tuna population status. – ICES Journal of Marine Science, 65: 612–622. Theory and limited observation suggest that fish schools consist of more individuals of similar size when populations are large than when they are small. The hypothesis that population size might be indicated by school structure is tested for southern bluefin tuna (SBT), a commercially important large pelagic species, which has undergone an estimated 60% reduction in juvenile biomass since 1960. Fish size data are used to determine whether there have been changes in schooling behaviour that can be used as simple indicators of abundance. During tagging studies, juvenile SBT are removed sequentially from a school, measured, tagged, and released. These sequential size measurements are used here to describe school composition from different years in two locations using simple school metrics (including mean fish size, variance in size, and mean difference in size between sequential fish). Trends were significant in most metrics over the 40-year period analysed, and were inversely related to independent estimates of population size. Simple school metrics are cost-efficient and easily interpreted by stakeholders. Monitoring population trends in near real time through school composition metrics may indicate further decline or recovery of SBT and, therefore, assist future management of tuna and other schooling species.

Abstract:

The objectives of this work were to determine the sample size (number of plants) necessary to estimate the indicators of the of multicollinearity degree - condition number (CN), determinant of the correlation matrix (DET), and variance inflation factor (VIF) - in productive traits of rye and to verify the variability of the sample size between the indicators. Five and three uniformity trials were conducted with the cultivars BRS Progresso and Temprano, respectively, and seven productive traits were evaluated in 780 plants. Twenty-one cases were obtained from seven traits, combined five to five. In each case, 197 sample sizes were planned (20, 25, 30, ..., 1,000 plants) and in each size 2,000 resampling were performed, with replacement. For each resample the CN, DET and FIV were determined and the average among 2,000 estimates of each indicator of the multicollinearity degree was calculated. Then, for each case and indicator, the sample size was determined through three models: models of maximum modified curvature, segmented linear with plateau response, and segmented quadratic with plateau response. There was superiority the quadratic model segmented with plateau in adjusting the degree of multicollinearity according to the sample size for all indicators. There is a need greater sample size to detect multicollinearity when diagnosed by DET and for sizes larger than 101, 258 and 102 plants when diagnosing for the number of conditions, determinant and inflation factor performed, respectively.

Abstract:

Abstract Size-based indicators are well established as a management tool in shelf seas as they respond to changes in fishing pressure and describe important aspects of community function. In the deep sea, however, vital rates are much slower and body size relationships vary with depth, making it less clear how size-based indicators can be applied and whether they are appropriate for detecting changes through time. The deep-sea fish stocks of the North Atlantic underwent a period of exploitation followed by management and conservation action that relieved this pressure. We used data from a deep-water bottom trawl survey in the Rockall Trough, at depths of 300–2000 m, to test whether size-based indicators changed over a 16-year period, during which fishing pressure decreased. We applied four indicators to these data: mean body length, mean maximum length, large fish indicator (LFI), and the slope of the biomass spectrum. Patterns were analysed within four different depth bands. The LFI and slope of the biomass spectrum showed positive change over time, suggesting recovery from fishing pressure. This response was generally most apparent in the shallowest depth band, where most fishing activity has been distributed. Values of the LFI were much higher overall than in shelf seas, so the same reference points cannot be applied to all marine ecosystems. These findings imply that size-based indicators can be usefully applied to the deep sea and that they potentially track changes in fishing pressure in the medium term.

Abstract:

Abstract High-resolution grain-size investigations were carried out in two SW Polish loess sections: Biały Kościół (Niemcza-Strzelin Hills) and Zaprężyn (Trzebnica Hills). Each sequence was sampled by using the same methodology and samples were taken at 5 centimeters intervals. The particle size distribution was obtained with a Mastersizer 2000 laser, used for diffraction methods. From the obtained results the basic parameters and grain size indicators were calculated: Mz, Grain Size Index ratio, U-ratio and the percentage content of clay (< 4μm) and sand (> 63 μm). Both loess-soil sequences are composed of interfluve and slope loess facies and consist of five litho-pedostratigraphic units developed during the Late Pleistocene and Holocene: two loess units L1LL1, L1LL2 and three polygenetic fossil soils sets S0, S1 and L1SS1. The distance between these two profiles is about 60 km. Zaprężyn, as a section located more to the north, has almost no lower younger loess and higher level of weathering which could be related to proximity of this site to the Ice Sheet margin. The climate here was more extreme and harsh. What is more, the difference in development of soil L1SS1 can be observed: while in Biały Kościół pedogenesis process was slower and less disturbed than in Zaprężyn. The upper part of L1SS1 in Biały Kościół was deformed by gelifluction, frost heave and other periglacial processes. Mz indicator by the grain-size distribution in these sediments reflects subtle variations in the climatic system. Moreover, in Zaprężyn the content of sand fraction is higher than in Biały Kościół what can be the evidence of short episodes of strong winds during cold period of sedimentation. The aim of this paper is to compare two loess profiles by their stratigraphical and lithological similarities which are result of climate conditions and features of surrounding environment.

Abstract:

Abstract. Growth curve modeling (GCM) is an important and commonly used methodology in the social sciences for examining change over time in a variable value. While much of the empirical research examining the performance of various estimators under a variety of conditions has focused on continuous (and typically normally distributed) observed indicators, in practice researchers frequently make use of categorical indicators with anywhere from two to as many as seven categories. Given the popularity of GCMs, along with the frequent use of categorical indicators, and the relative dearth of simulation research focusing on estimation of these models with such variables, the current study focused on the issue of parameter estimation accuracy as related to the number of categorical indicators, and the number of categories per indicator. Results of this research found that for models with only a linear component, parameter estimation was very accurate for as few as four indicators with two categories each and a sample size of 200. On the other hand, when the underlying model included both linear and quadratic terms, parameter estimation accuracy suffered for a small number of dichotomous indicators unless the sample size was 1,000 or more. However, with six or more indicator variables, and/or at least three categories, parameter estimation accuracy remained high.

Abstract:

Purpose – The purpose of this paper is twofold. First, the study aims to investigate the relationship between the altmetric indicators from ResearchGate (RG) and the bibliometric indicators from the Scopus database. Second, the study seeks to examine the relationship amongst the RG altmetric indicators themselves. RG is a rich source of altmetric indicators such as Citations, RGScore, Impact Points, Profile Views, Publication Views, etc. Design/methodology/approach – For establishing whether RG metrics showed the same results as the established sources of metrics, Pearson’s correlation coefficients were calculated between the metrics provided by RG and the metrics obtained from Scopus. Pearson’s correlation coefficients were also calculated for the metrics provided by RG. The data were collected by visiting the profile pages of all the members who had an account in RG under the Department of Physics, Panjab University, Chandigarh (India). Findings – The study showed that most of the RG metrics showed strong positive correlation with the Scopus metrics, except for RGScore (RG) and Citations (Scopus), which showed moderate positive correlation. It was also found that the RG metrics showed moderate to strong positive correlation amongst each other. Research limitations/implications – The limitation of this study is that more and more scientists and researchers may join RG in the future, therefore the data may change. The study focuses on the members who had an account in RG under the Department of Physics, Panjab University, Chandigarh (India). Perhaps further studies can be conducted by increasing the sample size and by taking a different sample size having different characteristics. Originality/value – Being an emerging field, not much has been conducted in the area of altmetrics. Very few studies have been conducted on the reach of academic social networks like RG and their validity as sources of altmetric indicators like RGScore, Impact Points, etc. The findings offer insights to the question whether RG can be used as an alternative to traditional sources of bibliometric indicators, especially with reference to a rapidly developing country such as India.

ObjectivesTo assess the utility of publicly reported performance trend results of Canadian hospitals (by hospital size/type and jurisdiction).DesignLongitudinal observational study.Setting489 hospitals in Canada between fiscal years 2012–2013 and 2016–2017.ParticipantsAnalysis focused on indicator results of individual Canadian hospitals.Primary and secondary outcomesEight outcome indicators of hospital performance: in-hospital mortality (2), readmissions (4) and adverse events (2). Performance trend outcomes of improving, weakening or no change over time. Comparators in performance by hospital size/type of above, below or same as average.ResultsAt the national level, between 2012–2013 and 2016–2017, Canadian hospitals largely reduced in-hospital mortality: hospital deaths (hospital standardised mortality ratio) −9%; hospital deaths following major surgery −11.1%. Conversely, readmission to hospital increased nationwide: medical 1.5%; obstetric 5%; patients aged 19 years and younger 4.6% and surgical 3%. In-hospital sepsis declined −7.1%. Approximately 10% of the 489 hospitals in this study had a trend of improving performance over time (n=49) in one or more indicators, and a similar number showed a weakening performance over time (n=52). Roughly half of the hospitals in this study (n=224) had no change in performance over time for at least four out of the eight indicators. No single hospital had an improving or weakening trend in more than two indicators. Teaching and larger-sized hospitals showed a higher ratio of improving performance compared with smaller-sized hospitals.ConclusionsAnalysis of Canadian hospital performance through eight indicators shows improvement of in-hospital mortality and in-hospital sepsis, but rising rates of readmissions. Subdividing the analysis by hospital size/type shows greater instances of improvement in teaching and larger-sized hospitals. There is no clear pattern of a particular province/territory with a significant number of hospitals with improving or weakening trends. The overall assessment of trends of improving and weakening as presented in this study can be used more systematically in monitoring progress.

Abstract:

The state of marine systems subject to natural or anthropogenic impacts can be generally summarized by suites of ecological indicators carefully selected to avoid redundancy. Length-based indicators capture the status of fish community structure, fulfilling the Marine Strategy Framework Directive (MSFD) requirement for Descriptor 3 (status of commercial fish species). Although the MSFD recommends the development of regional indicators, a comparison among alternative length-based indicators is so far missing for the Mediterranean Sea. Using principal component analysis and dynamic factor analysis, we identified the most effective subset of length-based indicators, whether or not based on maximum length. Indicator trends and time series of fishing effort and environmental variables are also compared in order to highlight the individual and combined capability of indicators to track system changes across geographical sub-areas. Two indicators, typical length and mean maximum length, constitute the smallest set of non-redundant indicators, capturing together 87.45% of variability. Only in combination can these indicators disentangle changes in the fish community composition from modifications of size structure. Our study supports the inclusion of typical length among the regional MSFD Descriptor 3 indicators for the Mediterranean Sea. Finally, we show dissimilarity between the western and eastern-central Mediterranean, suggesting that there are sub-regional differences in stressors and community responses.

Abstract:

Performance of agricultural entities can be observed from several different perspectives: using macroeconomic indicators, the quantity of agricultural production units, or by measuring the profitability. The paper present focuses on the relationship between profitability, return on sales (ROS) and wheat yields per hectare in agricultural entities in member states of the European Union (EU), divided into size categories by quantity standard output (SO). Due to the high proportion of subsidies in agriculture, the ROS indicator was rated in two versions: including subsidies and excluding subsidies. The aim of the paper is to confirm or refute the mutual relationship between these indicators, i.e. wheat yields per hectare, return on sales, and the size of the farm. The comparison is performed by means of indicators of descriptive statistics and tests of mathematical statistics. The results of the research show that return on sales drops with the size of the farm, while yields per hectare grow.

Abstract:

Across broad geographic scales, ecological indicators for fish assemblages should represent causal ecological processes, be sensitive enough to show patterns across the landscape, and reflect underlying biotic or abiotic conditions that influence those patterns. We assessed the responses of commonly applied ecological indicators for lake fish assemblages (mean body size, catch-per-unit-effort (CPUE), and normalized length size spectrum (NLSS) slope) to regional (climate, water chemistry, and watershed stress due to human activities) and local (lake morphometry, water quality, and angling pressure) ecological and anthropogenic variables. The indicators were estimated using fish assemblage catch data acquired via a standardized gillnetting protocol implemented within 693 lakes in Ontario, Canada. To our knowledge, our study is the first size-based or catch-based indicator evaluation to include detailed observations of angling pressure on hundreds of inland lakes. Boosted regression tree models showed that CPUE of large-bodied organisms and NLSS slope best described underlying patterns in the regional and local variables. Models developed with a mix of regional and local variables performed better than models developed with regional or local variables alone. The relative influences of the variables and responses varied among indicators, but in general, ecological variables had greater influence on the indicators than anthropogenic variables. These results emphasize the complex and multiscaled nature of factors and ecological processes affecting body size, habitat-community production, and trophic dynamics in lake fish assemblages.

Abstract:

The purpose of the work is to determine and analyze the peculiarities of correlations between the constitutional parameters of the body and personality indicators of practically healthy Ukrainian women of the first mature age. Primary anthropo-somatotypological (anthropometric examination according to the scheme of V. V. Bunak, determination of somatotype – according to the mathematical scheme of J. Carter and B. Heath; determination of fat, bone and muscle components of body weight – according to the formulas of J. Matiegka, determination of muscular components of body weight – according to the method of the American Institute of Nutrition) and indicators of personality (leading typological characteristics of temperament according to Eysenck, psychodynamic features of personality according to Spielberger, indicators of severity and features of accentuated personality traits according to Shmishek, indicators of subjective control according to Rotter) of 101 practically healthy Ukrainian women of the first mature age were selected from the data bank of materials of the research center of National Pirogov Memorial Medical University, Vinnytsya. The analysis of correlations between anthropo-somatotypological indicators and indicators of personality traits was performed in the licensed package "Statistica 6.1" using the statistical method of Pearson. Between anthropo-somatotypological indicators and indicators of personality traits of practically healthy Ukrainian women, mostly single weak-strength feedback and direct reliable correlations have been established. In most cases, the feedback is established with the leading typological characteristics of temperament according to Eysenck, psychodynamic features of personality according to Spielberger and indicators of severity and features of accentuated personality traits according to Shmishek, and direct – with indicators of subjective control according to Rotter. The multiple nature of the relationship only between the rate of accentuation of the character of the exalted type according to Shmishek with most indicators of the width of the distal epiphyses of the limbs and the size of the pelvis; between the level of subjective control in the field of failures according to Rotter with half the longitudinal sizes of the body; between the indicator of situational (reactive) anxiety according to Spielberger, or the indicator of accentuation of the character of the cyclothymic type according to Shmishek with all the girths of the chest. Quantitative analysis of significant correlations between anthropo-somatotypological indicators and indicators of personality traits of practically healthy Ukrainian women revealed the largest relative percentage of reliable correlations of anthropo-somatotypological indicators. Namely, with the leading typological characteristics of temperament according to Eysenck, the largest relative percentage of reliable relationships was established with transverse body size and somatotypological indicators; with psychodynamic features of the personality according to Spielberger – with somatotypological indicators; with indicators of severity and features of accentuated personality traits according to Shmishek – with longitudinal body dimensions, cephalometric indicators and width of distal epiphyses of extremities; with indicators of the level of subjective control according to Rotter – with longitudinal body size and somatotypological indicators.

Abstract:

Size plays an important role in sizing. The sort of size is various, and its various performance indicators are not comprehensive, so it brings very great difficulty to sizing workers. Through a large number of experiments, LX-6, PAM, SFB, LM, FY five kinds of solid poly-acrylic acid size of various performances had been tested, contrasted and analyzed. Meanwhile, the film-forming ability, and the adhesion of pure cotton roving and polyester-cotton roving were tested. Moreover, we did experiments on polyester cotton yarns, which were sized with these five kinds of size, and the sized yarn hairiness reduction rate, moisture regain, enhancement rate, reduction rate and other performance indicators had been tested, contrasted and analyzed. Results provide reference for the use of these five kinds of size.

Abstract:

It is known that both genetic factors and environmental influences affect the development of the human body. This statement also applies to a person’s personality, ie the big five – the main features that make it up. The study of the relationship between physique and personality traits among a healthy population is very relevant and is a promising area for anthropology and psychology. The purpose of the work is to conduct a prognostic assessment of the influence of anthropo-somatotypological indicators on the personality indicators in practically healthy Ukrainian women without and taking into account the somatotype. Primary anthropo-somatotypological (anthropometry according to Bunak’s scheme, Heath-Carter somatotype determination, Matiegka and American Institute of Nutrition weight composition) and personality indicators (determination of leading typological characteristics of temperament according to Eysenck, psychodynamic features of personality according to Spielberger and features of accentuated personality traits according to Shmishek, components of internality according to Rotter) of practically healthy Ukrainian women of the first mature age are selected from the data bank of materials of the research center of National Pirogov Memorial Medical University, Vinnytsya. Factor analysis was performed in the license package "Statistica 6.1". The main factors that indicate the association of personality traits of practically healthy Ukrainian women of different somatotypes with some anthropo-somatotypological indicators: mesomorphs – "the size of the girth and fat size of the body" and "the size of the longitudinal size of the body"; in ectomorphs – "the size of the girth of the body" and "the size of the fat size of the body"; in endo-mesomorphs - "the magnitude of the circumferential size of the body" and "the magnitude of the width of the mandible"; in representatives of the middle intermediate somatotype – "the magnitude of the longitudinal and circumferential dimensions of the body" and "the magnitude of SFT on the posterior surface of the shoulder." In the general group of women, it is impossible to single out the second factor that has a significant load. Analysis of the obtained relationships of interdependence of personality traits, which have the greatest prognostic value in terms of formation of human personality with anthropo-somatotypological indicators showed that women of different somatotypes identified interdependencies have certain features. Thus, the application of factor analysis made it possible to determine the most significant relationships of personality indicators with the constitutional parameters of the body in practically healthy Ukrainian women of different somatotypes.

Abstract:

Fluctuating asymmetry has been proposed as an indicator of environmental stress and population health. However, a notable feature of research examining the relationship between fluctuating asymmetry and population fitness is that of inconsistency. Logging dramatically alters habitat and has the potential to increase or decrease environmental stress. To evaluate the response of fluctuating asymmetry to logging, I conducted research to determine whether fluctuating asymmetry differs in the frog Crinia signifera captured at logged and unlogged sites and if any differences were correlated with body size or body condition. There was a decrease in fluctuating asymmetry but also a decrease in body size and body condition as a result of logging. I also investigated whether any relationship existed between the subtle asymmetry of individuals and the following indicators of fitness: clutch size, clutch mass, average egg mass, testes size, body size and body condition. There was no significant relationship between subtle asymmetry and the fitness indicators.

Abstract:

The category of personality is one of the basic concepts for psychology, but at the same time the most controversial in theoretical and methodological terms. That is why the study of personal characteristics in different populations, ethnicities, ages, professional groups, etc. still does not lose its relevance in the scientific field. Given that certain components of individual personality traits are innate, it is advisable to find connections between them and the characteristics of the human body. The purpose of the work is to determine and analyze the peculiarities of correlations between indicators of body structure and size and personality indicators of practically healthy women with mesomorphic somatotype. Primary anthropo-somatotypological and personality indicators of 33 practically healthy Ukrainian women of the first mature age of mesomorphic somatotype were selected from the data bank of materials of the research center of National Pirogov Memorial Medical University, Vinnytsya. The analysis of correlations between anthropo-somatotypological and indicators of personality traits was performed in the licensed package "Statistica 6.1" using the non-parametric Spearman's method. Multiple, mostly reliable, medium-strength straight lines (r = -0.35 to -0.50), Eysenck G. insincerity scales with the majority of girth dimensions, thickness of skin and fat folds, somatotype components, and body weight component composition; multiple, mostly significant medium-strength inverse (r = -0.37 to -0.52) correlations of the exaltation character of the exalted type according to Shmishek G. with the majority of girth dimensions, the majority of pelvic sizes, somatotype components and components of body weight composition; multiple significant mean strength inverse (r = -0.38 to -0.49) correlations of the extraversion-introversion scale according to Eysenck G. with the thickness of the skin and fat folds of the upper limb and under the shoulder blade. In other cases, single, medium-strength, reliable and unreliable direct and inverse correlations of anthropo-somatotypological indicators with the leading typological characteristics of temperament, psychodynamic features of personality and indicators of severity and features of accentuated personality traits. As a result of quantitative analysis of reliable and unreliable average correlations of anthropo-somatotypological indicators with personality traits of practically healthy women of mesomorphic somatotype, the highest relative percentage of correlations was found between: leading typological characteristics of temperament according to Eysenck G. and somatotype components body weight composition and body girth; psychodynamic personality traits according to Spielberger C. D. and longitudinal body size, thickness of skin and fat folds and components of the somatotype; indicators of severity and features of accentuated personality traits according to Shmishek G. and indicators of the component composition of body weight, somatotype components, body circumference and thickness of skin and fat folds; indicators of the level of subjective control over Rotter J. and the width of the distal epiphyses of the extremities and the transverse dimensions of the body.

Abstract:

Abstract This paper deals with the evaluation of selected available indicators of living standards, divided into three groups, namely economic, environmental, and social. We have selected six countries of the European Union for analysis: Bulgaria, the Czech Republic, Hungary, Luxembourg, France, and Great Britain. The aim of this paper is to evaluate indicators measuring living standards and suggest the most important factors which should be included in the final measurement. We have tried to determine what factors influence each indicator and what factors affect living standards. We have chosen regression analysis as our main method. From the study of factors, we can deduce their impact on living standards, and thus the value of indicators of living standards. Indicators with a high degree of reliability include the following factors: size and density of population, health care and spending on education. Emissions of carbon dioxide in the atmosphere also have a certain lower degree of reliability.

Abstract The study examines the performance of the Visegrád countries and Romania. As an indicator of innovation performance, we used the number of researchers measured from the active population. Due to the large variations in the size of the administrative-territorial units, the use of this ratio seems more adequate than using absolute values. The innovation indicator and the other indicators used are included in the analysis database in a regional breakdown. All indicators have an overview map of the entire large region for the purpose of establishing the territorial profile. In the course of the statistical investigation, each indicator was individually compared to the innovation index.

Full text

Abstract:

Species- and size-selective overexploitation often have ecosystem-wide impacts that are evident in community size spectra. To both derive potential ecosystem targets for community rebuilding and assess contemporary indicators relative to these targets, we constructed theoretical size spectra to predict pristine biomass densities using a combination of species- and size-specific nitrogen stable isotope signatures and a range of trophic efficiencies and primary productivity estimates within and among 3 sub-regions of the Newfoundland and Labrador shelf. Theoretical size spectra were compared to empirically derived size spectra using trawl survey data. The descending slopes of the empirically determined size spectra were between 1.25 and 2.42 times steeper than the theoretical slopes. The percentage of the theoretical distribution represented by the empirical size structure ranged between 1.1 and 29.4%, with the closest and furthest estimates associated with the smallest- and largest-sized fishes, respectively, and strongly influenced by estimates of trophic efficiency and primary productivity. Regional variation was also observed, with southern regions reaching 1.3-32.3% of the theoretical biomass density and the northernmost region reaching only 0-8.3%. Importantly, the descending slopes varied depending on fish size, with biomass density of larger sizes decreasing faster than that of smaller sizes. Variations among sub-regions and fish guilds were also observed. These analyses provide a means to derive potential ecosystem targets and indicators through which recovery of fish communities can be monitored and assessed.

Abstract:

The concept of sustainable agriculture is based on the paradigm of sustainable development. Sustainable agriculture refers to farm production systems and combines economic, social and environmental dimensions. Most often it covers issues related to environmental protection and improving the quality and standard of living of farmers. In conducting scientific research, the basic problems are measuring the degree of sustainability and classification of farms. The aim of the research was to develop an indicator measuring the economic dimension of sustainable agriculture and determine its size in various farm types. The assessment of individual groups of farms was based on an original set of indicators determining their economic situation. Consequently, the synthetic economic dimension indicator of sustainable agriculture (ESD) was used for farm evaluation. The conducted research showed that over 60% of groups of farms operating in 2010-2017 reached the target value of the indicator of the economic dimension of sustainable agriculture. Economic size and farm type were determinants of this situation. The results obtained indicate an increase in the economic dimension indicator of sustainable agriculture together with a higher class of economic size. Whereas the farms dealing with dairy were the type of farm with the highest values of the built indicator. Analysis of literature sources and the conducted research confirmed the complexity of the assessment of production systems and the impact of the choice of indicators on the degree of their sustainability.

Abstract:

This paper studied the relationships between anthropometry and physical fitness indicators that affect elite female tennis players’ training process planning. Bodyweight and height were measured as well as aerobic and anaerobic lactic capabilities, and the physiological indicators determined. Results showed reliable relationships between the anthropometric and functional fitness indicators and the players’ competitive performance. It was concluded that monitoring the average weight relative to the height of female tennis players can assist in the improvement of the players’ performance through changes in the training process, specifically by relating the weight and height indicators with the strengths and weaknesses of the players’ tactical patterns.

The paper provides data on the dependence of the sample indicators of the arithmetic mean, variance, asymmetry and excess of the length of the needles of European spruce (Picea rubra) and European larch (Larix decidua), the average length of a pair of needles of Scots pine (Pinus sylvestris) and Calabrian pine (Pinus brutia). The sizes of samples have been determined, which make it possible to obtain the values of the estimates of sample indicators that have stabilized around their general values. The data on the difference between the law of distribution of the length of the needles of coniferous plants from the normal one are confirmed. The possibility of using graphs of the dependence of sample indicators on sample sizes for the examination of scientific data is discussed.

Abstract:

A new indicator is described that uses multivariate posterior predictive data arising from management strategy evaluation (MSE) to detect operating model misspecification (exceptional circumstances) due to changing system dynamics. The statistical power of the indicator was calculated for five case studies for which fishery stock assessments have estimated changes in recruitment, natural mortality rate, growth, fishing efficiency, and size selectivity. The importance of the component data types that inform the indicator was also calculated. The indicator was tested for multiple types of management procedures (e.g., catch limits by stock assessment, size limits, spatial closures) given varying qualities of data. The statistical power of the indicator could be high even over short time periods and depended on the type of system change and quality of data. Statistical power depended strongly on the type of management approach, suggesting that indicators should be established that rigorously account for feedbacks between proposed management and observed data. MSE processes should use alternative operating models to evaluate protocols for exceptional circumstances to ensure they are of acceptable statistical power.

Abstract:

Indicator organisms are used to assess public health risk in recreational waters, to highlight periods of challenge to drinking water treatment plants, and to determine the effectiveness of treatment and the quality of distributed water. However, many have questioned their efficacy for indicating pathogen risk. Five hundred and forty cases representing independent indicator–pathogen correlations were obtained from the literature for the period 1970–2009. The data were analyzed to assess factors affecting correlations using a logistic regression model considering indicator classes, pathogen classes, water types, pathogen sources, sample size, the number of samples with pathogens, the detection method, year of publication and statistical methods. Although no single indicator was identified as the most correlated with pathogens, coliphages, F-specific coliphages, Clostridium perfringens, fecal streptococci and total coliforms were more likely than other indicators to be correlated with pathogens. The most important factors in determining correlations between indicator–pathogen pairs were the sample size and the number of samples positive for pathogens. Pathogen sources, detection methods and other variables have little influence on correlations between indicators and pathogens. Results suggest that much of the controversy with regards to indicator and pathogen correlations is the result of studies with insufficient data for assessing correlations.

Abstract:

ObjectivesThe objective was to assess the possibility of using a combination of official and unofficial Facebook ratings and comments as a basis for nation-wide hospital quality assessments in Norway.MethodsAll hospitals from a national cross-sectional patient experience survey in 2015 were matched with corresponding Facebook ratings. Facebook ratings were correlated with both case-mix adjusted and unadjusted patient-reported experience scores, with separate analysis for hospitals with official site ratings and hospitals with unofficial site ratings. Facebook ratings were also correlated with patient-reported incident scores, hospital size, 30-day mortality and 30-day readmission. Facebook comments from 20 randomly selected hospitals were analysed, contrasting the content and sentiments of official versus unofficial Facebook pages.ResultsFacebook ratings were significantly correlated with most patient-reported indicators, with the highest correlations relating to unadjusted scores for organisation (0.60, p<0.000) and nursing services (0.57, p<0.000). Facebook ratings were significantly correlated with hospital size (−0.40, p=0.003) and 30-day mortality (0.31, p=0.040). Sentiment analysis showed that 84.7% of the comments from unofficial Facebook sites included neutral comments that did not give any specific description of experiences of the quality of care at the hospital. Content analysis identified common themes on official and unofficial Facebook pages.ConclusionsFacebook ratings were associated with patient-reported indicators, hospital size, and 30-day mortality. Qualitative comments from official Facebook are more relevant for hospital evaluation than unofficial sites. More research is needed on using Facebook ratings as a standalone indicator of patient experiences in national quality measurement, and such ratings should be reported together with research-based patient experience indicators and with explicit criteria for the inclusion of unofficial sites.
