A comparison in the effectiveness of the Olson Circumplex Model and the Walsh Integrated Approach on couples’ resilience and conflicts

Introduction: The present study was conducted aiming to compare the effectiveness of Olson Circumplex Model and Walsh Integrated Approach on the couple’s resiliency and conflict. Method: In the experimental mehtod, 30 couples owning the qualifications cited by the researcher and those who referred to the counseling offices in zone 3 of Tehran in 2014 becasues of marital conflicts were selected through random sampling and were randomly put into experimental and control groups (two experimental and one control group). Both experimental groups were put under the effect of independent variables (i.e., Olson Model and Walsh Approach) during eight nineteen-toa hundred twenty minue sessions. The applied instruments were resilience scale (CD-RISC) and Marital Conflicts Questionnaire (MCQ). Finally, the collected data were analyzed via MANOVA method. Findings: Results taken from the data analysis implied that there is a significant difference between the mean scores of the experimental and control groups in the variables of marital resilience and conflicts compared to the control group (p<0.05). No significant difference was observed in the resilience variable when investigating the comparison of the degree of effectiveness of the two approaches (P>0.05). However, there was a significant difference between two groups in the variable of marital conflicts and the means and it showed that Olson Circumplex Model enjoyed a higher effectiveness in reducing the couples’ marital conflicts than the Walsh Integrated Approach. Conclusion: According to the findings of the study, Olson Circumplex and Walsh Integrated Approach can be applied to decrease the couples’ marital conflicts.
Measuring weekly consumer confidence

This paper puts forward a data collection method to measure weekly consumer confidence at the individual level. The data thus obtained allow to statistically analyze the dynamic correlation of such a consumer confidence indicator and to draw inference on transition rates, which is not possible for currently available monthly data collected by statistical agencies on the basis of repeated cross-sections. An application of the method to various waves of data for the Netherlands shows its merits. Upon temporal aggregation we also show the resemblance of our data with those collected by Statistics Netherlands.
Association of N2-fixing cyanobacteria with wheat (Triticum vulgare L.) roots

Two locally prevailing hetyerocystous cyanobacterial isolates, collected from alluvial clay soil and identified as Nostoc muscorum and Anabaena variabilis, were tested (either singly or mixed) for their potency to colonize the roots of wheat seedlings. N. muscorum formed close association with root hairs, whereas A. variabilis showed loose binding. The mixture of both cyanobacterial strains formed weak association with the roots of wheat seedlings. The tight colonization of N. muscorum led to accumulation of Chl "a" in the roots, as well as showed a beneficial influence on stimulating nitrogenase activity. Such tight association by N. muscorum significantly increased the growth parameters of wheat seedlings. Dry weight of the inoculated plant seedlings roots augmented by more than 3-fold of the control, wherever the shoots were promoted by more than 36% as compared to the control has no inoculation. However, the loose attachment shown by A. variabilis contributed to the weak association of the mixture of both cyanobacterial agents. Key words: Nostoc muscorum, Anabaena variabilis, Triticum variabilis, cyanobacterial isolates.
Stroop test software. The Tastiva proposal

There has been a great deal of research on emotional information processing within the field of clinical psychology. Many tests have been developed and the emotional Stroop test is one of the most used. However, some versions of the Stroop test have methodological issues when used to study word-colour interferences, especially when the words are emotionally charged. We present a computer-assisted version of the emotional Stroop test called Tastiva, which is highly versatile, useful, and accessible, in addition to being easy to use and widely applicable. The Tastiva software and User Manual is available on the University of Seville website: http://grupo.us. es/recursos/Tastiva/index.htm. We also present a case study using neutral and sexual content words, in which the program calculates the word exposure time by analysing the behaviour of the respondent. One of its novel contributions is the graphic presentation of meas-ures: response time, errors, and non-response to stimuli.
Continuos-flow microfluidics Digital microfluidics Mixing DropletSeparation Liquid marble Microfluidic liquid handling

The interdisciplinary research field of microfluidics has the potential to revolutionize current technologies that require the handling of a small amount of fluid, a fast response, low costs and automation. Microfluidic platforms that handle small amounts of liquid have been categorised as continuous-flow microfluidics and digital microfluidics. The first part of this paper discusses the recent advances of the two main and opposing applications of liquid handling in continuous-flow microfluidics: mixing and separation. Mixing and separation are essential steps in most lab-on-a-chip platforms, as sample preparation and detection are required for a variety of biological and chemical assays. The second part discusses the various digital microfluidic strategies, based on droplets and liquid marbles, for the manipulation of discrete microdroplets. More advanced digital microfluidic devices combining electrowetting with other techniques are also introduced. The applications of the emerging field of liquid-marble-based digital microfluidics are also highlighted. Finally, future perspectives on microfluidic liquid handling are discussed.
Adaptive Second Order Sliding Mode Control of a Fuel Cell Hybrid System for Electric Vehicle Applications

We present an adaptive-gain second order sliding mode (SOSM) control applied to a hybrid power system for electric vehicle applications. The main advantage of the adaptive SOSM is that it does not require the upper bound of the uncertainty. The proposed hybrid system consists of a polymer electrolyte membrane fuel cell (PEMFC) with a unidirectional DC/DC converter and a Li-ion battery stack with a bidirectional DC/DC converter, where the PEMFC is employed as the primary energy source and the battery is employed as the second energy source. One of the main limitations of the FC is its slow dynamics mainly due to the air-feed system and fuel-delivery system. Fuel starvation phenomenon will occur during fast load demand. Therefore, the second energy source is required to assist the main source to improve system perofrmance. The proposed energy management system contains two cascade control structures, which are used to regulate the fuel cell and battery currents to track the given reference currents and stabilize the DC bus voltage while satisfying the physical limitations. The proposed control strategy is evaluated for two real driving cycles, that is, Urban Dynamometer Driving Schedule (UDDS) and Highway Fuel Economy Driving Schedule (HWFET).
Optimal Inventory Policy for Deteriorating Items with Seasonal Demand under the Effect of Price Discounting on Lost Sales

In this paper an inventory model is developed with seasonal quadratic demand and time proportional deterioration. Shortages are considered and are partially backlogged. At the start of shortage period price discount is declared on unit selling price for backordered quantity so as to enhance the demand and to reduce the lost sales which in turn maximizes the total profit per unit time. Numerical illustration and sensitivity analysis of the optimal solution with respect to various parameters is carried out to describe the model. Kew Words: Deterioration, Partial backlogging, Seasonal demand, Price discounting.
Atomic and electronic structure of GaP/Si(111), GaP/Si(110), and GaP/Si(113) interfaces and superlattices studied by density functional theory

The atomic structure of GaP(111)/Si(111), GaP(110)/Si(110), and GaP(113)/Si(113) heterointerfaces was studied by ab initio calculations employing the density functional theory (DFT). Relative formation energies were computed for the interface layers allowing for atomic intermixing. The application of the electron-counting model, a construction principle used for surface reconstructions, to the case of the GaP(111)/Si(111) interfaces leads to electronic compensation at the heterovalent interfaces and to a reduction of the interface formation energy. The specific equilibrium (111) interface reconstruction can be tuned by changing the chemical potential. In particular, the GaP(111)A/Si(111) interface was found to be abrupt and uncompensated under P-rich conditions, whereas it is compensated under Ga-rich conditions. The GaP(111)B/Si(111) interface was found to be compensated. Contrary to the (111) interfaces, stoichiometric abrupt interfaces were found to be the most energetically favorable for the GaP(110)/Si(110) and the GaP(113)/Si(113) interfaces. These interfaces do not reconstruct. Although both interfaces are compensated, the GaP(113)/Si(113) superlattice exhibits a polarization field, in contrast to the (110) superlattice.

Multi-scale Generative Adversarial Networks for Crowd Counting

We investigate generative adversarial networks as an effective solution to the crowd counting problem. These networks not only learn the mapping from crowd image to corresponding density map, but also learn a loss function to train this mapping. There are many challenges to the task of crowd counting, such as severe occlusions in extremely dense crowd scenes, perspective distortion, and high visual similarity between pedestrians and background elements. To address these problems, we proposed multi-scale generative adversarial network to generate high-quality crowd density maps of arbitrary crowd density scenes. We utilized the adversarial loss from discriminator to improve the quality of the estimated density map, which is critical to accurately predict crowd counts. The proposed multi-scale generator can extract multiple hierarchy features from the crowd image. The results showed that the proposed method provided better performance compared to current state-of-the-art methods
Chemical composition and antimicrobial activity of Sudanese Lupinus termis L. root extracts

The root of Lupinus termis L. , a leguminous plant of great potential growing in northern Sudan and native to the Mediterranean basin was investigated phytochemically and assessed for its antimicrobial activity. Previous phytochemical, pharmacological and clinical investigations based on ethnopharmacologic approach recommended the use of the seed ethanolic extract as a safe herbal remedy in treatment programs of shingles. Herein we report the Lupin root oil extracted with petroleum ether from the sweet variety investigated for its lipid profile as well as the quinolizidine alkaloid profile of the root methanolic extract. The GC-MS analysis showed that the oil was composed mainly of oleamide (43.1%); hydrocarbons (26.2%); fatty alcohols (15.8%) and fatty acids (09.58%). The semi-purified alkaloid methanolic extract was composed mainly of lupanine (72%); 13-hydroxylupanine (6.6%); sparteine (4.6%); ammodendrine (3.8%) and 13- Methoxylupanine (2.5%). The two extracts were assessed for their antimicrobial activity and the microorganisms were resistant to the oil extract and were moderately sensitive to the methanolic extract.
Variations of the Somali upwelling since 18.5 ka BP and its relationship with southwest monsoon rainfall

Abstract. Somali upwelling history has been reconstructed for the last 18.5 ka BP based on biogenic silica fluxes estimated from a sediment core retrieved from the western Arabian Sea. Surface winds along the east African coast during the southwest monsoon (SWM) cause the Somali upwelling; thus, the intensity of this upwelling has been related to the variability of the SWM. Biogenic silica flux variation suggests periodic weakening and strengthening of the Somali upwelling. Weakened upwelling during the 18.5–15 ka BP period and strengthened upwelling during the Bølling–Allerød (15–12.9 ka BP) suggest the onset of the SWM. The Younger Dryas (12.9–11.7 ka BP) is marked by reduced upwelling strength, with an intensification of the Somali upwelling observed at the beginning of the Holocene and a further decline at 8 ka BP. The increase in the upwelling strength recorded since 8 ka BP suggests SWM strengthening during the latter part of the Holocene. A comparison of upwelling variations with the SWM precipitation record demonstrates a reversal in the relationship between the strength of the Somali upwelling and SWM rainfall at the beginning of the Holocene. This observed shift has been attributed to the variation in the SWM strength due to the latitudinal shift of the intertropical convergence zone (ITCZ) associated with changes in moisture sources.
The Factors Affecting Vietnam Airlines Service Quality and Passenger Satisfaction – A Mediation Analysis of Service Quality

Abstract–This study was conducted to investigate and evaluate the overall service quality dimensions of the airline service. Quantitative method was carried out with a sample size of 300 respondents who travelled with Vietnam Airlines. The results indicated that better employee’s services, facilities, image, timeliness, ground service, safety, baggage service, and perceived service quality were positively associated passenger satisfaction. In addition, this study showed that employee’s services, image, and timeliness played the most important roles in predicting passenger satisfaction.
Crosstalk Analysis and Optimization of Gaussian Networks-on-Chip

Gaussian-based optical networks-on-chips (ONoCs) have significant topological advantages over mesh and torus networks in terms of network diameter and average jump distance. However, the crosstalk noise that accumulates in the network can cause severe performance degradation and limit the scalability of the network. Therefore, this paper analyzes the three aspects of basic optical elements, optical router and network, and proposes a Gaussian-based ONoCs worst-case crosstalk noise and signal-to-noise ratio (SNR) analysis model. In addition, we use Cygnus and crossbar optical routers for numerical simulations to verify the feasibility of the proposed analytical model. In order to improve the availability of Gaussian networks, we propose an optimization method to improve network performance that can effectively avoid the worst case.
INITIAL EVALUATION OF 3D RECONSTRUCTION OF CLOSE OBJECTS WITH SMARTPHONE STEREO VISION

Abstract. The Worldwide spread of relatively low cost mobile devices embedded with dual rear cameras enables the possibility of exploiting smartphone stereo vision for producing 3D models. Despite such idea is quite attractive, the small baseline between the two cameras restricts the depth discrimination ability of this kind of stereo vision systems. This paper presents the results obtained with a smartphone stereo vision system by using two rear cameras with different focal length: this operating condition clearly reduces the matchable area. Nevertheless, 3D reconstruction is still possible and the obtained results are evaluated for several camera-object distances.
ECO: Egocentric Cognitive Mapping

We present a new method to localize a camera within a previously unseen environment perceived from an egocentric point of view. Although this is, in general, an ill-posed problem, humans can effortlessly and efficiently determine their relative location and orientation and navigate into a previously unseen environments, e.g., finding a specific item in a new grocery store. To enable such a capability, we design a new egocentric representation, which we call ECO (Egocentric COgnitive map). ECO is biologically inspired, by the cognitive map that allows human navigation, and it encodes the surrounding visual semantics with respect to both distance and orientation. ECO possesses three main properties: (1) reconfigurability: complex semantics and geometry is captured via the synthesis of atomic visual representations (e.g., image patch); (2) robustness: the visual semantics are registered in a geometrically consistent way (e.g., aligning with respect to the gravity vector, frontalizing, and rescaling to canonical depth), thus enabling us to learn meaningful atomic representations; (3) adaptability: a domain adaptation framework is designed to generalize the learned representation without manual calibration. As a proof-of-concept, we use ECO to localize a camera within real-world scenes---various grocery stores---and demonstrate performance improvements when compared to existing semantic localization approaches.
Exploiting Orientational Redundancy in Multiview Video Compression

This article introduces an approach for the acquisition and coding of multiview video. Multiview video systems consist of several cameras simultaneously capturing a single scene. Therefore a significant level of inter-view redundancy is present among the videos that can be exploited into video compression. Inspired by the idea of motion estimation in MPEG4 video compression, we introduce the idea of rotation estimation and compensation that is used in conjunction with motion estimation and compensation in order to remove spacial as well as temporal redundancies from the compressed video. The main question to be answered is how to choose the best sequence of compression among the frames when both time and space domains are involved. In this article, we model the above problem as a minimum cost graph traversal problem where cameras are considered as graph nodes and the cost of an edge connecting two cameras is inversely proportional to the similarity between the videos recorded by those cameras. We will then find the solution of this problem as the optimal traversal sequence that result in a high compression ratio.
How we Ensured Rigour in a Multi-site , Multi-discipline , Multi-researcher Study

Qualitative research has often been criticised for its lack of rigour. In order to overcome this, measures of trustworthiness, dependability and reliability have been suggested. A study of how pastoralists learn to incorporate sustainable farming systems in the tropical savannas of Australia employed multiple-researchers, working in three States and from a variety of disciplines. To ensure rigour a framework for the study was developed by the researchers prior to commencing interviews. This was followed by regular teleconferences to ensure that the framework was valid and to adjust for any problems encountered along the way. Every interview was analysed independently by all researchers before a workshop was conducted to bring the ideas together. Categories and ideas within the data were synthesised to create an overall understanding of the learning process within the confines of "landcare" in the Tropical Savannas. These processes were undertaken in consultation with the pastoralists and the process has been explicitly documented to enable readers to follow the research process easily. The rigour in this project is shown in the clear documentation of the research process carried out by individual researchers and by the team when it met. The understanding of pastoralists' learning processes is our interpretation; it is up to the reader to decide whether s/he agrees with that interpretation, but from the description of the process it is easy for the reader to see where and why her/his interpretation differs.

Multi-Criteria Approach for Measuring Stakeholder Perception on the Impacts of Tourism Policy

Recognizing the role stakeholders have in the tourism development process, this paper focuses on assessing tourism impacts related to the tourism policy priorities from the point of view of destination stakeholders in three well-known tourism destinations in the South Bohemian Region in the Czech Republic. Its aim is to analyze stakeholder perception of tourism impacts and identify such priorities which have the greatest anticipated impacts on developing a given destination. The research is based on a mix of qualitative research approach and innovative application of the Analytic Hierarchy Process (AHP). The representatives of three stakeholder groups provide the researchers with information about the importance of economic and non-economic tourism impacts and contributions of tourism policy’s strategic priorities to four categories of tourism impacts. Based on comprehensive data analysis, the researchers construct a three-level hierarchical structure mapping the importance of various tourism impacts, then sorting the priorities with respect to stakeholder preferences, and finally identifying a gap between the actual and preferred orientations of tourism policy. In such a way, the paper offers a comprehensive recipe for local governments which can be instrumental in realizing tourism policy while being able to promote the most important impacts of tourism on destination’s development from the point of view of destination stakeholders.
