Abstract:

This paper uses principal component analysis to discuss variables nature, which affects Internet of Things (IOT) growth from input perspective. It discusses relevance of these variables and the goals of the research. Research shows that: in the stage of IOT growth, capital investment, science and technology investment are the main variables affecting industry growth, human investment is the secondary variable. Policy support is strongly correlated with the level of IOT development.

Abstract:

This study analyzes the prevalence and characteristics of childhood and adolescence sexual abuse suffered by a sample of university students, as well as the variables associated with the nature of abuse. Participants anonymously completed the Questionnaire on Child Sexual Abuse, in order to obtain information about experience of sexual abuse. Of a total of 2,375 students, 289 (12.2%) declared having suffered sexual abuse before the age of 18. The invasiveness, continuity, and severity of abuse was related to the location where the abuse took place (the more severe cases were committed in the homes of the victim and perpetrator) and to the circumstances of abuse (relationships with partners/at a party or while caring for a child predicted more severe abuse). The age of the victim (preschool) and an intrafamilial relationship between victim and perpetrator were also related to more invasive, continuous, and severe sexual abuse. The knowledge of characteristics of perpetrator and victim and the context in which sexual abuse occurs can help to better comprehend the nature and correlates of sexual abuse. The results of the present study may contribute to the design of programs for the prevention of sexual abuse to minors.

Abstract:

Purpose The purpose of this paper is to provide the empirical evidence supporting the existence of a multi-level hierarchical TQM model showing the structural inter-relationships among a total of 16 TQM variables (i.e. drivers, enablers and outcomes). Design/methodology/approach The set of identified TQM variables is the product of an in-depth review of the literature, and a robust reiterative process of verification and validation. Inter-relationships among the TQM variables were subjected to the scrutiny of a panel of experts, and were used as a basis for developing a web-based survey to explore the existence as well as strength of the structural relationship between each and every pair of the identified variables using interpretive structural modelling and MICMAC (Impact Matrix Cross-Reference Multiplication Applied to a Classification). Findings TQM variables were classified and clustered based on their influence and dependence on each other. Variables such as commitment by top management and customer satisfaction appear to have a strong chance to affect change, whereas variables such suppliers and competitors are very dependent on, and sensitive to, the evolution of the influent variables. Originality/value The paper demonstrates a multi-level TQM model encompassing all identified TQM drivers, enablers, and outcomes. The paper not only addresses a gap in the relevant literature (reduces the evidence scarcity about the hierarchical nature of TQM variables), but also gives insights into the variables with most driving power needing greater management attention.

Abstract:

We examine how the binomial distribution B(n,p) arises as the distribution Sn = ∑i=1nXi of an arbitrary sequence of Bernoulli variables. It is shown that B(n,p) arises in infinitely many ways as the distribution of dependent and non-identical Bernoulli variables, and arises uniquely as that of independent Bernoulli variables. A number of illustrative examples are given. The cases B(2,p) and B(3,p) are completely analyzed to bring out some of the intrinsic properties of the binomial distribution. The conditions under which Sn follows B(n,p), given that Sn-1 is not necessarily a binomial variable, are investigated. Several natural characterizations of B(n,p), including one which relates the binomial distributions and the Poisson process, are also given. These results and characterizations lead to a better understanding of the nature of the binomial distribution and enhance the utility.

Abstract:

Despite their centrality to the scientific enterprise, both the nature of scientific variables and their relation to inductive inference remain obscure. I suggest that scientific variables should be viewed as equivalence classes of sets of physical states mapped to representations (often real numbers) in a structure preserving fashion, and argue that most scientific variables introduced to expand the degrees of freedom in terms of which we describe the world can be seen as products of an algorithmic inductive inference first identified by William W. Rozeboom. This inference algorithm depends upon a notion of natural kind previously left unexplicated. By appealing to dynamical kinds—equivalence classes of causal system characterized by the interventions which commute with their time evolution—to fill this gap, we attain a complete algorithm. I demonstrate the efficacy of this algorithm in a series of experiments involving the percolation of water through granular soils that result in the induction of three novel variables. Finally, I argue that variables obtained through this sort of inductive inference are guaranteed to satisfy a variety of norms that in turn suit them for use in further scientific inferences.

Abstract:

The classical-quantum duality at the basis of quantum theory is here extended to the Planck scale domain. The classical/semiclassical gravity (G) domain is dual (in the precise sense of the classical-quantum duality) to the quantum (Q) elementary particle domain: [Formula: see text], [Formula: see text] being the Planck scale. This duality is universal. From the gravity (G) and quantum (Q) variables [Formula: see text], we define new quantum gravity (QG) variables [Formula: see text] which include all (classical, semiclassical and QG) domains passing through the Planck scale and the elementary particle domain. The QG variables are more complete than the usual ([Formula: see text], [Formula: see text]) ones which cover only one domain (Q or G). Two [Formula: see text] or [Formula: see text] values [Formula: see text] are needed for each value of [Formula: see text] (reflecting the two dual ways of reaching the Planck scale). We perform the complete analytic extension of the QG variables through analytic (holomorphic) mappings which preserve the light-cone structure. This allows us to reveal the classical-quantum duality of the Schwarzschild–Kruskal spacetime: exterior regions are classical or semiclassical while the interior is totally quantum: its boundaries being the Planck scale. Exterior and interior lose their difference near the horizon: four Planck scale hyperbolae border the horizons as a quantum dressing or width: “l’horizon habillé”. QG variables are naturally invariant under [Formula: see text]. Spacetime reflections, antipodal symmetry and PT or CPT symmetry are contained in the QG symmetry, which also shed insight on the global properties of the Kruskal manifold and its present renewed interest.

Abstract:

Abstract Military operations have an evolving character that responds to the changes in the nature of the conflict. The basic nature of the operation is given by the operational themes. These have a major impact on related military activities and on their tactical tasks. The commander at the tactical level, in order to achieve the end state of the operation, must fully understand the mission, respect the superior’s intent and perceive the conditions, circumstances and influences of each individual characteristic element of the assigned area of operation. The instruments to achieve this status of comprehension are tactical variables (Mission, Enemy, Terrain and Weather, Troops available, Time available, Civil considerations - METT-TC). The aim of the article is to describe tactical variables, which at the tactical level serve as the tool for mission analysis.

Abstract:

AbstractA brief review of the nature and subtypes of cataclysmic variables (CVs) is given. The catalogue of CVs is still very incomplete. All-sky surveys should add large numbers of CVs, which will improve knowledge of the space density of these systems. It is pointed out that the nova-like variables, which are the most difficult to discover, are the subtype having the highest space density. Their discovery is therefore the highest priority – they fix the frequency of CVs, which is important in population syntheses of binary stars.

Abstract:

The present article proposes a taxonomy of features to describe the grammar of natural landscapes with the parameters that can account for the preferences of speakers in the description of nature. The taxonomy is the theoretical foundation designed for the Corpus of Language and Nature (CLAN Corpus),1 compiled worldwide, whose aim is to describe the cognitive and emotional preferences in the observation of nature by speakers of different languages. For this purpose, we have delineated the basic visual features deemed essential to read natural landscapes in order to create a network of cognitive variables in the perception of nature with its various components and features. These features of landscapes are complemented with a description of the cognitive variables that mould the individual’s perception of nature and the emotions enacted after its contemplation.

Abstract:

On lit souvent que les modèles de risque « tiennent compte du passé » ou « possèdent une mémoire ». Contrairement à une croyance répandue, ceci n’est vrai que pour le quotient instantané de base et non pour la variation du quotient en fonction d’une variable indépendante fonction du temps (VIFT). Le quotient instantané de base varie en fonction du temps mesuré depuis l’origine, mais l’effet de la VIFT est markovien par construction : l’estimation de l’effet de la VIFT ne tient compte que de l’état occupé à chaque instant et pas des états occupés auparavant. En conséquence, son effet n’est pas conditionnel aux états occupés antérieurement. L’article examine cette question en adoptant le point de vue de la statistique mathématique, notamment en distinguant la populationthéoriqueconstruite à l’aide de modèles de risque et la populationréelleetfiniedont sont tirés les échantillons de personnes. L’examen se fait au moyen d’un exemple simple : l’effet de la situation conjugale sur la première naissance étudié à partir des données de l’Enquête sociale généralede 2006.

Abstract:

AbstractThe observational properties and outburst histories of each member of the small class of recurrent novae are reviewed, with the objective of identifying the outburst mechanisms for these systems. Examples are found of both accretion-powered outbursts (T CrB and RS Oph) and thermonuclear-powered outbursts (T Pyx and U Sco). Outburst properties which might be used in future to distinguish between these mechanisms are identified. Many erstwhile recurrent novae (VY Aqr, RZ Leo, V616 Mon, V1195 Oph, V529 Ori, WZ Sge, and V1017 Sgr) appear to be misclassified examples of other types of cataclysmic variables.

Abstract:

We empirically test separation of ownership and control (SOC) and the interaction of SOC with farmer effort on farm success using data from the U.S. Department of Agriculture's Agricultural Resource Management Survey. We use a two-stage least-squares approach with instrumental variables that proxy for participation constraints in binding incentive contracts. We find that the interaction has a significantly positive effect on success for grain farms and an insignificant effect for livestock farms. The results are consistent with hypotheses by Allen and Lueck (1998), but our model predicts that farms with SOC are likely to be more successful than farms without SOC despite exogenous uncertainty and agency costs.

Abstract:

Odor and olfaction anthropology explores four lines of research which, in many cases, may overlap: the variability of the olfactory perception, olfactory skills and know-how, odor use, and odor representations. My proposal here is to deal with the first one, trying to answer the following question: is olfactory perception a phenomenon resulting solely from the biological organization of the human being, in such a way that it does not know other variations than the ones due to nature? Or, on the contrary, can we show different kinds of olfaction culturally determined or, at least, environmental influences resulting in significant perceptual differences among groups, societies, cultures, etc.? In the first part of the text, I will deal with the invariants (or universals). In the second, I will insist on the cultural types of olfaction. In the third and last part, I will advance the following proposal: beyond the discussion on the roles that nature and culture play in human olfaction, we can sustain that naturally and culturally, there is a way of smelling characteristic of our species. Finally, I will conclude with two examples of the symbolic treatment characteristic of the olfactory human experience.

Full text

Abstract:

OH/IR stars are the infrared counterparts of galactic OH maser sources which show a characteristic double-peaked emission-line profile. Their strong radio emission can be detected at large distances, making them excellent tracers of distribution and kinematics of evolved stars in the Milky Way. The OH maser profile is typical for line emission from an expanding circumstellar shell. The circumstellar shells of OH/IR stars absorb the optical emission of the central star nearly completely and reemit the energy in the infrared. Having luminosities ~ 105 L⊙ and energy distributions peaking around 10μm, they may make a major contribution to the interstellar radiation field beyond 5μm. With mass loss rates of 10-5 to 10-4 M⊙/yr they lose several solar masses in a few hundred thousand years. OH/IR stars are therefore important objects for recycling stellar matter into the interstellar medium.Progress has been made in understanding the nature of OH/IR stars. They are Mira-like large-amplitude variables with periods up to 5 years long. It is proposed that they are stars of intermediate mass (2–10 M⊙) on the asymptotic giant branch (AGB). They have not only larger masses than Mira variables proper, but also longer periods of pulsation and larger mass loss rates. As a result optically thick circumstellar dust shells are formed, which prevent the detection of these more massive Mira-like variables at optical wavelengths. Radial pulsation (Mira variability) is thus thought to occur for all intermediate-mass stars in the course of their evolution on the AGB. In view of their high mass-loss rates, these stars may be key objects in the study of the formation of planetary nebulae.

Full text

Abstract:

Automated predictions require explanations to be interpretable by humans. Past work used attention and rationale mechanisms to find words that predict the target variable of a document. Often though, they result in a tradeoff between noisy explanations or a drop in accuracy. Furthermore, rationale methods cannot capture the multi-faceted nature of justifications for multiple targets, because of the non-probabilistic nature of the mask. In this paper, we propose the Multi-Target Masker (MTM) to address these shortcomings. The novelty lies in the soft multi-dimensional mask that models a relevance probability distribution over the set of target variables to handle ambiguities. Additionally, two regularizers guide MTM to induce long, meaningful explanations. We evaluate MTM on two datasets and show, using standard metrics and human annotations, that the resulting masks are more accurate and coherent than those generated by the state-of-the-art methods. Moreover, MTM is the first to also achieve the highest F1 scores for all the target variables simultaneously.

The constructs of the system are: referent, meaning value, meaning unit and meaning variables describing its contents and structure. Its properties are: operational activation, complexity, development, regressiveness, self-embeddedness, selectivity, and dynamism. The meaning test and the meaning profile enable assessment. Meaning manifestations in cognition, personality, emotions, and consciousness are described.

Abstract:

AbstractTwo low-amplitude variable supergiants in the Large Magellanic Cloud, S65-08 and S65-48 are each found to have periods of approximately 250 days. The cfptical data suggest that these stars are high-luminosity cepheid variables falling more than one magnitude brighter than any other known Cepheids in the LMC. Confirmation of the cepheid nature of these stars comes from their H-band magnitudes which place them accurately on a simple linear extrapolation of the narrower infrared Period-Luminosity relation. So it appears that the cepheid Period-Luminosity relation extends up to Mv ~ -8.5. To honour the astronomer who discovered the first of these highest-liminosity Cepheids, we have sub-classified the variables with log P > 1.8 as being “Leavitt variables”. As soon as these long-period variables are discovered in other external galaxies, reliable distances should be possible out to (m-M) ~30.

Abstract:

Purpose: To examine whether patients’ experiences could be improved during colonoscopy by designing the examination room to include a digital screen showing calm nature films. Background: Colonoscopy is the gold standard for examination of the large intestine and the rectum. Around 50% of individuals invited for colorectal cancer screening choose to refrain from the screening due to fear and anxiety. It is therefore important to improve patients’ comfort during the procedure. Method: One of the four endoscopy rooms was rebuilt to include a large digital screen showing calm nature films. Patients were randomized to intervention (i.e., the room showing films) or control. During the colonoscopy, pulse and oxygen saturation were measured and the patients graded the intensity of pain and anxiety. Blood samples were taken regularly during the examination and were analyzed for glucose, cortisol, and prolactin. Results: The presence of calm nature films during colonoscopy decreased the release of cortisol, increased prolactin levels, and enhanced oxygen saturation. These effects were more apparent in patients who were unfamiliar with the procedure and the environment, patients who underwent the examination without analgesics or sedation, and patients whose examination procedure was relatively difficult and took a long time. Conclusions: The intervention described in this study is easy to implement and might help improve the patient experience during colonoscopy. However, this study was performed in a single health institution, and more studies are needed to further explore the role of film interventions in endoscopic and other medical procedures.

AbstractIf Luminous Blue Variables (LBVs) are not each unique types, three broad groups can be characterized depending on the luminosity and location ofLBVsin the Hertzsprung-Russell diagram. To assist in defining the evolutionary nature ofLBVs, connections are made to stars that have similar spectral character with the suggestion that some of these objects that may someday becomeLBVs.

Abstract:

PurposeThis paper aims to investigate the impact of the efficiency of working capital management (WCM) on the performance of a sample of Indian companies and explore how the nature of the firm's business influences the significance and direction of this impact.Design/methodology/approachThe data for this study were collected for the period of 2012–2018 for 414 non-financial firms listed on the Bombay Stock exchange. Fixed-effect regression models were run by taking Tobin's Q and return on equity (ROE) as dependent variables, and net trade cycle (NTC) and its components as explanatory variables in the presence of liquidity, leverage, size, age and growth as control variables. Sample firms were segregated into manufacturing, trading and service groups, and regression models were used for all the groups to understand the effect of the nature of a firm's business.FindingsWCM efficiency has a significant impact on the performance of the sample firms. Non-financial Indian firms deliver better financial performance by maintaining lower NTC. Like NTC, its components also impact firm value and profitability. The results report that the significance of the relationship varies depending upon the nature of the firm's business.Originality/valueThe previous research studies had not used a sample of large number of Indian firms. Unlike previous studies, this study reports the influence of the nature of business on the relationship between WCM and firm performance. Further, this paper also examines how the individual components of working capital influence the performance of Indian firms.

Abstract:

This pilot study investigates the extent of familiarity among primary school children (6th grades, n = 142, 55.6 % boys) with common local animal and plant species and whether this knowledge differs depending on selected context variables. As the analysis shows, nature is of great importance, and most children already have gathered some basic experience of nature. On average, they correctly identified 51.2 % of the animals and 36.2 % of the plants, but there were obvious gaps in their knowledge. The present results showed a clear connection between the knowledge of native animal and plant species depending on the child’s nationality, whether they have a garden at home and how their parents stimulate their interest in nature.

Abstract:

Lifetime psychedelic substance use has previously been linked to nature relatedness and pro-environmental behaviour. Yet, participants’ responses to the self-report measures in these studies may have been affected by stereotypical associations or confirmation bias. We therefore re-examined this link by measuring three pro-environmental dependent variables: nature relatedness, concerns about climate change, and objective knowledge about climate change. Additionally assessing lifetime experience with 30 psychoactive substances, we collected an international convenience sample for an online survey ( n = 641), Controlling for age, educational attainment, and covariation in substance use indicators, psychedelic use (primarily the use of psilocybin) predicted objective knowledge about climate change directly, and indirectly via nature relatedness. Further, it predicted concern about climate change indirectly via nature relatedness. The results suggest that the relationship of psychedelics with pro-environmental variables is not due to psychological biases, but manifests in variables as diverse as emotional affinity towards nature as well as knowledge about climate change.

Abstract:

AbstractWritten and spoken language are known to differ substantially (Biber, 1988; 1995; Biber, Johansson, Leech, Conrad, & Finegan, 1999). Standard written language is highly uniform and governed by prescription, whereas the vernacular is most revealing of structured heterogeneity (Weinreich, Labov, & Herzog, 1968). We focus on four English morphosyntactic variables that problematize assumptions about the nature of variation in the vernacular: the genitive, the comparative, the dative, and relative pronouns. Each is characterized in casual speech by functional divides that reflect discrete configurations of variant use. After detailing the patterning of these variables in speech, we explore a characteristic arguably shared by each: its historical pathway into the language, where analogy and prestige were powerful motivations for variant choice. We suggest that this combination of systemic and social factors contributed to the nature of these variables in the vernacular grammar. Furthermore, we advocate for greater scrutiny of written and spoken data and the outcomes of change from above and below within each register. The type of innovation and its trajectory may affect the nature of the emergent variable grammar.

Abstract:

Economics as a subject is regarded as the bedrock of all management and social science-based disciplines. The persistently low level of students’ achievement in economics in senior secondary school examinations has become a thing of great concern to all stakeholders. This study examined students’ performance in the Senior Secondary School economics qualifying examination in Kano State and the influence of sex and schools' nature on their performances in economics. An ex-post facto design of descriptive research was adopted for the study. A proforma was used to collect data from a sample of 300 students, selected using a stratified random sampling procedure from the secondary schools in Kano State, Nigeria. The data were analysed using descriptive statistics and an independent-sample t-test to test the hypotheses. Overall results showed that students performed above average and a significant gender difference exists in economics performance. Similarly, there is no significant difference in students’ performance with respect to the schools' nature (boarding and day schools). Keywords: Economics, examination, students’ performance, school nature

Abstract:

In this paper, a method for states, parameters, and fractional order estimation is presented. The proposed method is an extension of the traditional dual estimation method and uses three blocks of filters with appropriate data interconnections. As the main part of the estimation algorithm, the Fractional Unscented Kalman Filter was used. The proposed Triple Estimation algorithm might be treated as a convenient tool for estimation and analysis of a wide range of dynamical systems with fractional constants or variable order nature, especially when knowledge about the identified system is very restricted and both order and system parameters are unknown. In order to show the performance of the proposed algorithm, sets of numerical results are presented.

Abstract:

Abstract Causation is a macroscopic phenomenon. The temporal asymmetry displayed by causation has no counterpart in the fundamental dynamics of the microscopic world. So causation must somehow emerge from the underlying dynamics, along with other macroscopic phenomena like entropy increase and the arrow of radiation. In this paper I shall offer an account of causation that accounts for this emergence. I shall show how macroscopic events fall into lawlike patterns that are subject to the random influences of microscopic processes. It is the probabilistic independence of these random influences that constitutes these laws as temporally asymmetric and causal. I shall approach these issues by considering ‘causal inference’ techniques that allow causal relations to be inferred from sets of observed correlations. I shall show that these techniques are best explained by a reduction of causation to structures of equations with probabilistically independent exogenous terms. This exogenous probabilistic independence imposes a recursive order on these equations and a consequent distinction between dependent and independent variables that lines up with the temporal asymmetry of causation.
