Validation of the Psychometric Properties of Acceptance and Action Questionnaire-II in Clinical and Nonclinical

This study explores the factor structure of the Acceptance and Action Questionnaire (AAQ-II) in both clinical and general normative groups. It also examines the factorial invariance of a one-factor proposed model in both groups. Data was collected from the overall database of a Portuguese Cognitive and Behavioral Research Center ( N = 687, 425 females; mean age= 36 years; SD = 11.33). Con(cid:192)rmatory Factor Analysis supported a one-factor structure with good internal consistencies and construct related validity. The one-factor solution was also supported with a second independent data set, which showed a con(cid:192)gural, strict measurement and structural invariance of the one-factor solution proposed. Multigroup Con(cid:192)rmatory Factorial Analysis showed the con(cid:192)gural invariance, weak measurement invariance and also structural invariance of the one-factor model of Acceptance and Action Questionnaire II across both groups under study. The one-factor model have both similar meanings and the same structure, but the measurement model in clinical and nonclinical groups was not the same. Toxic in(cid:193)uences of experiencial avoidance as a core mechanism in the development and maintenance of several clinical disorders, may explain why the questionnaire that assesses experiential avoidance, as efforts to not come into contact with unpleasant private events such as thoughts, feelings, enotions, sensations, by trying to change their occurence, form or frequency specially when doing so leads to undesirable outcomes. Items are rated on a 1 (never true) to 7 (always true) scale; higher results mean high experiential avoidance. AAQ-II has a mean alpha coef(cid:192)cient of . 84 (from .78 to .88) and the 3 and 12 months teste-retest reliability was . 81 and . 79, respectively. The AAQ-II scores concurrently, longitudinally and incrementally predict several outcomes, from mental health to work absence rates. The AAQ-II also shows appropriate discriminat validity and appears to measure the same concept of AAQ-I with better psychometric (Bond et al. , 2011). In the present study the internal consistency, Cronbach’s alpha was . 92.

Changes in soil moisture and riparian forest structure after a dam construction

- This study evaluated the impacts of water fl ow reduction in soil moisture and changes in the arboreal community in a riparian forest in Minas Gerais. Our hypothesis is that few years after river fl ow reduction can alter soil moisture and change tree community structure. We performed soil moisture analyses to confi rm reduction in soil moisture and a four-year-monitoring of the tree community structure in 1.1 ha of riparian forest. Soil moisture was reduced, especially during the dry season at the sector located near the original river fl ow. In this sector we found higher mortality and broken stems of living trees, strongly reducing basal area and causing a little reduction in trees density. This study highlights the strong impacts of dams’ construction in the fl ora and water availability downstream from the dam. vivas, fortemente Este os fortes da de na fl
SHORT NOTE (NOTA CORTA) POTENTIAL USE OF CROP RESIDUES AS LIVESTOCK FEED RESOURCES UNDER SMALLHOLDER FARMERS CONDITIONS IN BALE HIGHLANDS OF ETHIOPIA (POTENCIAL DE LOS RESIDUOS DE COSECHA COMO ALIMENTO PARA RUMIANTES BAJO CONDICIONES DE PEQUEÑOS PRODUCTORES EN ETIOPÍA)

SUMMARY The study was conducted in Sinana Dinsho district of Bale Highlands, which has bimodal (Sinana sub district) and mono modal (Dinsho sub district) rainfall patterns. Data on available crop residues and feeding practices in the district were obtained in a baseline survey involving 195 farmers to generate information on the importance of crop residues available for animal feeding in the district. Nutrient content of major crop residues of wheat, barley, emmer wheat, linseed, field pea, faba bean and maize were determined. The availability of each type of crop residues varied (P 0.05) on crude protein (CP), neutral detergent fiber (NDF) contents and in vitro dry matter digestibility (IVDMD) of the crop residues in Sinana. The IVDMD of wheat straw was lower (P < 0.05) than that of barley and emmer wheat. Hemicellulose content of cereal crop residues was higher (P < 0.001) than that of pulses and linseed. In general, the crop residues were low in CP and IVDMD, but high in fiber content, and thus require some degree of supplementation or treatment to support reasonable livestock performance.

: The deployment of a sustainable recycling network for electric vehicle batteries requires the development of an infrastructure to collect and deliver batteries to several locations from which they can be transported to companies for repurposing or recycling. This infrastructure is still not yet developed in North America, and consequently, spent electric vehicle batteries in Canada are dispersed throughout the country. The purpose of this reverse logistics study is to develop a spatial modeling framework to identify the optimal locations of battery pack dismantling hubs and recycling processing facilities in Canada and quantify the environmental and economic impacts of the supporting infrastructure network for electric vehicle lithium-ion battery end-of-life management. The model integrates the geographic information system, material ﬂow analysis for estimating the availability of spent battery stocks, and the life cycle assessment approach to assess the environmental impact. To minimize the costs and greenhouse gas emission intensity, three regional recycling clusters, including dismantling hubs, recycling processing, and scrap metal smelting facilities, were identiﬁed. These three clusters will have the capacity to satisfy the annual ﬂow of disposed batteries. The Quebec–Maritimes cluster presents the lowest payload distance, life-cycle carbon footprint, and truck transportation costs than the Ontario and British Columbia–Prairies clusters. Access to end-of-life batteries not only makes the battery supply chain circular, but also provides incentives for establishing recycling facilities. The average costs and carbon intensity of recycled cathode raw materials are CAD 1.29/kg of the spent battery pack and 0.7 kg CO 2e /kg of the spent battery pack, respectively, which were estimated based on the optimization of the transportation distances.

Critical infrastructure systems are tightly-coupled socio-technical systems with complicated behavior. They have emerged as an important focal point of research due to both their vital role in the normal conduct of societal activities as well as their inherent appealing complications for researchers. In this chapter, we will report on our experience in developing techniques, tools and algorithms for revealing and interpreting the hidden intricacies of such systems. The chapter will include the description of several of our technologies that allow for the guided understanding of the current status quo of infrastructure systems through the As-trolabe methodology, the formal profiling of infrastructure systems using the UML-CI meta-modeling mechanism, and also observing the emergent behavior of these complex systems through the application of the agent-based AIMS simulation suite.
Mining of Mineral Deposits

Purpose. In this paper we present and validate an analytical model of water inflow and rising level in a flooded mine and examine the model robustness and sensitivity to variations of input data considering the examples of three closed hard-coal mines in Germany. Methods. We used the analytical solution to a boundary value problem of radial ground water flow to the shaft, treated as a big well, and water balance relations for the series of successive stationary positions of a depression cone to simulate a mine water rebound in the mine taking into account vertical distribution of hydraulic conductivity, residual volume of underground workings, and natural pores. Findings. The modeling demonstrated very good agreement with the measured data for all the studied mines. The maximum relative deviation for the mine water level during the measurement period did not exceed 2.1%; the deviation for the inflow rate to a mine before its flooding did not exceed 0.8%. Sensitivity analysis revealed the higher significance of the residual working volume and hydraulic conductivity for mine water rebound in the case of thick overburden and the growing significance of the infiltration rate and the flooded area size in the case of lower overburden thickness. Originality. The developed analytical model allows realistic prediction of transient mine water rebound and inflow into a mine with layered heterogeneity of rocks, irregular form of the drained area, and with the inflow/outflow to a neighboring mine and the volume of voids as a distributed parameter without gridding the flow domain performed in numerical models. Practical implications. The study demonstrated the advantages of analytical modeling as a tool for preliminary evaluation and prediction of flooding indicators and parameters of mined out disturbed rocks. In case of uncertain input data, modeling can be considered as an attractive alternative to usually applied numerical methods of modeling ground and mine water flow.

Mining of Mineral Deposits

Purpose. The research is intended to investigate and synthesize adaptive control over drilling by identifying parameters of an object model under non-stationarity conditions. Methods. Under conditions of rapidly changing borehole drilling indices, a two-level adaptive control strategy is applied, combining investigation of drilling and its control. The structure of the control system includes an additional block of forming the model on the basis of data on indirect features. Findings. The research develops a method for seeking the extremum developed for the object whose dynamics is described by a first-order linear differential equation. The method allows to determine the value of the output signal by evaluating the initial phase of the transient process caused by the changed input signal for a set step. Originality. The suggested algorithm of noise-free identification makes it possible to assess the factor of the control object transfer under the action of random disturbances. The data obtained is used to adjust the gain factor of the controller in the closed loop automatic control system of drilling. Practical implications. The suggested structure and algorithm of drilling control allow enhancing drilling efficiency by ensuring relevant mechanical drilling rates through defining corresponding rotation speeds and axial loads of a drilling tool.
The Need for Teaching Undergraduate Students the Pesticides Label Contents In Faculties of Agriculture

Pesticides labels contain specific information that is of interest at various pesticide handling stages. In current study, 14 students from Faculty of Agro Based Industry, University Malaysia Kelantan, Malaysia were assessed on their ability to understand the content of 14 pesticides product labels. The results of this study indicate that students were able to retrieve information such as hazard class, manufacturer and signal word with accuracy of 97.5 %, 98.7 % and 86.2 % without any formal training, respectively. Meanwhile, the worst performances of students were in retrieving information of the type of formulation from the pesticide product label which, only 4 responses (5 %) were accurate.

We o ﬀ er a synthetic exposition on the state of the art for Computational Fluid Dynamics (CFD) relevant to the Navier–Stokes equations with the Boussinesq approximation, smoothly blending a history of the ﬁeld with an accessible exposition of the underlying mathematical rationale, supporting theorems and a survey of the landmark results on the subject. Attention is paid to those e ﬀ orts which have opened up new paradigms in modern CFD, the techniques that have emerged as leading candidates as well as their diverse reverberations in producing advancements in our understanding of thermal buoyancy convection (especially Rayleigh–Bénard convection and the so-called Hadley Flow) in both laminar and turbulent conditions.
Alternative Approaches to Estimate Returns to Scale in DEA- Models

This paper presents a number of approaches to estimate returns to scale properties of general multiple-input muliple-output technologies. Both qualitative scale efficiency-properties and quantitative scale elasticity-properties are covered. The estimation approaches considered are based on data envelopment analysis (DEA)-models using primal production data on inputs and outputs. We propose an approach to estimate scale elasticity based on the primal efficiency problem. This alternative approach is derived as a direct approximation of the differentials of the efficiency measures in the scale elasticity definition. The different approaches to estimate scale efficiency and scale elasticity are exemplified and compared using a small dataset.
A comparison of methods used in flood-frequency studies for coastal basins in California

This study compares the results of regional flood-frequency studies made by several methods and appraises the relative reliability of these methods. The areas selected for study were the subhumid San Diego area in southwestern California and the humid coastal area in northwestern California. The following six methods of analysis were applied to each region: Index-flood method, multiple correlation, logarithmic normal distribution, extreme-value probability distribution (Gumbel method), Pearson type III distribution, and gamma distribution. The last four methods named involved not only the computation of the statistics appropriate to the distributions, but also the relating of these statistics to basin and climatologic characteristics. On the basis1 of an empirical, nonstatistical test, the following conclusions were reached : 1. All methods of analysis give better results in a humid region than in a subhumid region because streamflow is less variable in a humid region. 2. If historical data, either qualitative or quantitative, are available concerning the magnitude of floods that occurred in the years prior to the collection of streamflow records, the multiple-correlation method of analysis is preferred. Only this method and the index-flood method benefit from the historical data, which, in effect, extend the time base of the analysis. The multiple-correlation method is superior to the index-flood method because it has a far more rational basis and in addition gives better results. 3. Where the peak-discharge data are limited entirely to the period during which streamflow records were collected (no historical data available), a method based on the distribution of the array of peak flows is preferred because of its greater objectivity. Of the four distributions tested, the Pearson type III is the most desirable. It is more flexible than the other three and will generally fit the peak-discharge data best. Although this comparison study of flood-frequency methods was based on small samples from only one part of the United States, the results and conclusions appear to be meaningful because they can be explained rationally.
New Trends in Classification and Data Mining

The classification of scientific papers is based on the ability of the artificial system (let’s call such a system ARSA i.e. Automated Review of Scientific Articles) to reflect the similarity of different scientific papers and differential of similar papers. To identify the text as similar to and different from other texts a set of characteristics needs to be used. In this paper the approach of the extraction of “linguistic items” from scientific paper that provides representative information about the document content is considered.

Exact theory for localized envelope modulated electrostatic wavepackets in space and dusty plasmas

Abundant evidence for the occurrence of mod- ulated envelope plasma wave packets is provided by recent satellite missions. These excitations are characterized by a slowly varying localized envelope structure, embedding the fast carrier wave, which appears to be the result of strong modulation of the wave amplitude. This modulation may be due to parametric interactions between different modes or, simply, to the nonlinear (self-)interaction of the carrier wave. A generic exact theory is presented in this study, for the nonlinear self-modulation of known electrostatic plasma modes, by employing a collisionless fluid model. Both cold (zero-temperature) and warm fluid descriptions are discussed and the results are compared. The (moderately) nonlinear os- cillation regime is investigated by applying a multiple scale technique. The calculation leads to a Nonlinear Schr ¨ odinger- type Equation (NLSE), which describes the evolution of the slowly varying wave amplitude in time and space. The NLSE admits localized envelope (solitary wave) solutions of bright- (pulses) or dark- (holes, voids) type, whose characteristics (maximum amplitude, width) depend on intrinsic plasma pa- rameters. Effects like amplitude perturbation obliqueness (with respect to the propagation direction), finite tempera- ture and defect (dust) concentration are explicitly consid- ered. Relevance with similar highly localized modulated wave structures observed during recent satellite missions is discussed.
Analytic, structural, and experimental testing of permanent magnet synchronous machine controller using Typhoon HIL

The goal of the paper is to present a workflow for 3-way validation of a permanent magnet synchronous machine field-oriented controller. The first model is based on the analytical approach building a system model using Energetic Macroscopic Representation (EMR) for the complete test facility. The second approach is to use the dedicated structural components from the Typhoon HIL schematics software library. These virtual replicas are then validated by results obtained in the same operational condition from the actual test bench. In doing so, the study targets proving the accuracy of the virtual models with regards to the behavior of the real setup.
Quantitative Evaluation of Passenger Flow at Metro Stations Based on Coarse-to-Fine Analysis

The dense urban metro network plays an important role in urban transportation, and it is becoming increasingly important to improve the operation and management of metro facilities. The monitoring and management of passenger flow is a main concern in metro operation, and the reliable analysis of passenger flow can greatly improve the operational efficiency and safety of a metro station. Therefore, using the long-time in-and-out smart card data of Shenzhen metro stations, this paper proposes a Coarse-to-Fine passenger flow analysis method for the characterization of passenger flow on multiple time scales. This method, which is proposed from a new perspective based on the time series clustering of metro stations, precisely defines the peak travel hours and then extracts features for the evaluation of the crowdedness and disorderliness at each station. Finally, the metro stations are classified into nine levels according to those features. The stations that need urgent attention in terms of their passenger flow, including Shenzhen North Station, Buji, and Grand Theater, are identified for the reference of city managers.
Emergency Evacuation Guidance Optimization in Urban Open Public Spaces

This study proposes a new emergency evacuation guidance optimization method for emergency evacuation management in urban open public spaces. The method has three advantages compared with traditional methods. (1) It optimizes the spatial allocation of evacuation guiders with the consideration of the distance-decay effect of guiding quality and the intervisibility between guiders and evacuees. (2) The evacuation guiding information transfers and the conformity behaviors of the evacuees are considered in emergency evacuation simulation, which make the simulation procedures more in line with the real evacuation situations. (3) By comparing simulation results under different evacuation guidance scenarios, the optimized evacuation guiding paths and strategies of guiders can be generated, which improves the guidance security and efficiency.
