ANTS And POTS: Do They Change Lives? Students Perceptions on the Value of Positive Psychology Concepts

Positive psychology provides a different perspective to that of traditional psychology. There is a growing research base of scientific study to validate the significance of this psychological approach in people’s lives. Enabling courses have an increased number of students utilising them as an alternative pathway to gain access to university. These courses have an important structural role in the development and up-skilling of students to assist with a positive transition into undergraduate studies. The Skills for Tertiary Education Preparatory Studies (STEPS) course offers a unique unit of study which introduces students to Positive Psychology as a means for students to develop the psychological resilience required on the student learning journey. Positive Learning for University (PLU), takes students on a personal and academic journey where they learn about theories that underpin Positive Psychology and can apply strategies to themselves personally and to their role as students. This article looks at three concepts that students found most beneficial: positive thinking, signature strengths, and resilience and considers why these resonate with students.
Urban Female Labor Force Participation and Its Correlates: A Comparative Study of Slum-Dwellers and Their Urban Counterparts of Three Metro Cities in India

This paper deals with an important but neglected aspect of female labor force participation (LFP) in urban India. Contemporary literature that deals with urban female LFP in India typically focuses on the entire urban sector, and invariably misses out one important aspect of urban living – the slums and its dwellers. This study attempts to fill that critical gap by examining two different household surveys side-by-side: a primary survey particularly focused on households living in slums and slum-rehabilitated colonies and the nationally representative Indian Human Development survey-II. It brings outs a comparative picture of nature, type jobs that women take up and various correlates of female LFP from both slum- and non-slum areas of three metro cities of India, viz. Delhi, Kolkata and Mumbai. It further explores the similarities and differences of the correlates for female LFP among the slum-clusters of these cities. It is found that despite being poorer and marginalized in many ways the slum dwelling women’s work participation rate is not extra-ordinarily high compared to their non-slum urban counterparts. In slums, a higher percentage of women are engaged in self-employment (including family business) and casual employments (includes domestic helps), whereas in non-slum areas somewhat more women are engaged in regular salaried jobs. Analysis identifies correlates that have similar effects across slum and non-slum areas – relationship between education and FLFP reflects a flat-bottom J-shaped pattern; being married, higher child dependency ratio and household heads with higher education significantly constrain women’s work choice; strong income effect of other household members earning on FLFP, but asset holding has no bearing. However, there are other factors that affect FLFP differently in slums and non-slum areas. These findings help us drawing important policy prescriptions.
Future research avenues of cost of quality: a systematic literature review

The purpose of this paper is to identify the future research suggestions which have been made by several authors with regard to cost of quality (CoQ) and to group them into respective themes. ,This study was based on a systematic literature review (SLR) of 97 peer-reviewed journal articles in the field of CoQ published in well-known academic databases, such as Emerald, Elsevier, SpringerLink, Taylor & Francis, Wiley and Scopus. The time horizon for reviewing the literature was 9 years, particularly in the period between 2010 and 2018. The “Affinity diagram” was applied to group the future research suggestions into logical themes and the “Pareto diagram” to further categorize and prioritize these themes. ,A plethora of future research suggestions identified in the literature are analytically presented. Moreover, the analysis showed that the future research suggestions in the field of CoQ can be grouped under eleven meaningful themes, which are further categorized into two broad categories, meaning the vital and the useful. ,This SLR was based on only fully accessed English articles published in international, peer-reviewed journals of the selected publishers. The restricted number of keywords used and the subjectivity in applying the “affinity diagram” are also limitations of this study. ,This paper provides insights into the future research perspectives in the field of CoQ. Thus, this analysis can serve as a resource for both researchers and practitioners to further develop this area according to the future research suggestions and the respective themes revealed. ,To the best of the authors' knowledge, this is the first SLR presenting and analyzing the future research suggestions of CoQ.
Cross-Scale Feature Fusion for Object Detection in Optical Remote Sensing Images

For the time being, there are many groundbreaking object detection frameworks used in natural scene images. These algorithms have good detection performance on the data sets of open natural scenes. However, applying these frameworks to remote sensing images directly is not very effective. The existing deep-learning-based object detection algorithms still face some challenges when dealing with remote sensing images because these images usually contain a number of targets with large variations of object sizes as well as interclass similarity. Aiming at the challenges of object detection in optical remote sensing images, we propose an end-to-end cross-scale feature fusion (CSFF) framework, which can effectively improve the object detection accuracy. Specifically, we first use a feature pyramid network (FPN) to obtain multilevel feature maps and then insert a squeeze and excitation (SE) block into the top layer to model the relationship between different feature channels. Next, we use the CSFF module to obtain powerful and discriminative multilevel feature representations. Finally, we implement our work in the framework of Faster region-based CNN (R-CNN). In the experiment, we evaluate our method on a publicly available large-scale data set, named DIOR, and obtain an improvement of 3.0% measured in terms of mAP compared with Faster R-CNN with FPN.
Ansættelse af seniorer: Hvilken type virksomheder rekrutterer seniorer – og hvorfor?

I de senere år er der sket en markant ændring i seniorernes vilkår på arbejdsmarkedet. Antallet af beskæftigede seniorer er nærmest eksploderet. Beskæftigelsesfrekvensen blandt de 55-64-årige er steget fra 56 til 71 i perioden 2000 til 2018. Imidlertid ved vi meget lidt om, hvor på arbejdsmarkedet seniorerne har fundet beskæftigelse, hvorfor formålet med denne artikel er at analysere, hvad det er for type virksomheder (og brancher), der især er disponerede for at ansætte nye 55-64-årige medarbejdere. Det væsentligste fund er, at seniorer rekrutteres på virksomheder, hvor gennemsnitsalderen på arbejdspladsens ledelseslag er høj, men især på virksomheder hvor der i forvejen er mange seniorer ansatte. Ligeledes har virksomhedens størrelsen en betydning for, om der rekrutteres seniorer. Især store virksomheder er tilbøjelige til at trække seniorer ind i virksomheden.

A hydrodynamic model for discontinuous shear-thickening in dense suspensions

Restricted sliding or rotational motion of colloidal particles plays a key role in the emergence of discontinuous shear thickening (DST). From viscometric functions to the number of contacting neighbors under an applied deformation, a hindrance to sliding motion significantly changes the behavior of dense suspensions on all scales. In this work, implicitly by using a modified hydrodynamic model based on Stokesian dynamics and explicitly by solving for the hydrodynamics of nonsmooth colloids, we show that lubrication forces that arise from surface asperities effectively provide such constraints to tangential particle motion. A transition from continuous shear thickening to DST is observed as the surface roughness of the particles is systematically increased. In this hydrodynamic model for DST, normal stress differences remain negative in the shear-thickened state (STS). Study of the spatial stress distribution indicates the onset of DST to be a highly localized event; however, particle self-diffusivity and the microstructural network suggest a rather uniform structure in the STS.
Metals Doped CdS Quantum Dots: Structural, Optical and Photocatalytic Properties under Visible Light Irradiation

Cadmium sulphide quantum dots (CdS-QDs) were obtained by a precipitation method. Studies on the structural, optical and photocatalytic properties of undoped and metals (M = Fe, Ag, Zn) doped CdS were investigated. The structural properties of the metals composite CdS were analyzed using X-ray diffraction (XRD) and Infrared (IR) techniques. Optical properties of the composite materials were characterized by absorption and photoluminescence techniques. XRD pattern reveals the undoped and metals doped QDs have highly crystalline in nature with cubic phases. High transmission electron microscopy (TEM) shows the spherical shape of particles with approximately 3-4 nm in sizes. The crystallite sizes of CdS are increased with doping of metals but slightly different the sizes of XRD and TEM images. The band gap values of CdS, Fe:CdS, Ag:CdS, and Zn:CdS calculated by Tauc plot are predicted as 3.64, 3.50 eV, 3.43 and 3.35 eV respectively. Upon doping metals, shift in band gap of QDs toward the longer wavelength with the increases of crystallite sizes is observed and depends on type of metals. The emission peak of QDs is appeared at 521 nm along with a shoulder at 430 nm which confirms of cadmium vacancies in the lattice. The emission intensity of QDs is decreased when metals are included. The emission peaks of metals doped QDs are gradually decreased over the increasing irradiation time and influenced by the nature of metal. The photo-catalytic activity and efficiency degradation are dependent of metals which may due to different crystal quality in Ag, Fe and Zn into CdS QDs composite. Present results suggest that Zn:CdS composite enhanced with superior photo-degradation efficiency and photo-catalytic activity under the sunlight.
Analysis and Improved Design of Phase Compensated Proportional Resonant Controllers for Grid-Connected Inverters in Weak Grid

Phase compensated proportional resonant (PR) controllers with phase leading angles embedded into resonant controllers, are used to improve the system stability, when the grid-connected inverter is connected to a weak grid with large grid impedance. However, an inappropriate phase leading angle will cause obvious anti-peak in the magnitude response of phase compensated PR controller. Thus, the phase leading angle should be selected carefully. The conventional phase compensation (CPC) method for selecting the phase leading angle can maximize the system phase margin, but at the expense of large peaks in the magnitude response of sensitivity transfer function. Meanwhile, the bandwidths of resonant controllers will be reduced. In the paper, an improved phase compensation (IPC) method is proposed, which does not cause peaks in the magnitude response of sensitivity transfer function while providing sufficient phase margin. Experimental tests were carried out on a single phase grid-connected inverter. The effectiveness of the proposed method is proved in terms of the steady-state and transient performances, as well as the performance under the grid frequency deviation.
Preference of Diversity Frame When Choosing Universities among Chinese High School Students

This study seeks to examine the relationship between Chinese high school students’ schooling abroad experience and their preference for instrumental or moral diversity frame, and further explore the mediation mechanism. In the present study, we take schooling abroad experience as the independent variable, and take attending preference of university with moral or instrumental diversity frame as the dependent variable. We have two sets of mediators: the first set of mediators are perceived minority/majority based on past experience and severity of unfair/biased experience based on nationality, and the second set of mediators are expected value, sense of belonging and possibility of being treated with bias in two universities. We send out questionnaires to 100 Chinese high school students. The statistical methods used in our analysis were ANOVA, correlation, and regression. The results are partly contrary to our expectation as there was no significant relationship between schooling abroad experience and preference of diversity frames, as well as severity of unfair/biased experience. The only validated path is between perceived minority/majority and preference of diversity frames, which is mediated by participants’ expected sense of belonging and possibility of being treated with bias at the instrumentally motivated university. Then, we explain our results considering status of Asian Americans in the United States, adjustment and some other aspects.

Folded Spiral Resonator with Double-Layered Structure for Near-Field Wireless Power Transfer

In this paper, a folded spiral resonator with a double-layered structure for near-field wireless power transfer is proposed. In near-field wireless power transfer, conjugate impedance matching is important to achieve high transfer efficiency. To achieve maximum available efficiency, it is common to connect a matching circuit to the antenna. However, the loss increases if a matching circuit is used. A coupling inductor with a resonant capacitor has the capability to adjust an imaginary part of the input impedance, whereas the folded spiral resonator has the capability to adjust both the imaginary and real parts of the input impedance. This resonator can achieve the maximum available efficiency without a matching circuit. This paper shows that the folded spiral resonator with a double-layered structure realizes high transfer efficiency compared to conventional models.

Tribalism in War and Peace: The Nature and Evolution of Ideological Epistemology and Its Significance for Modern Social Science

Abstract We argue that because of a long history of intergroup conflict and competition, humans evolved to be tribal creatures. Tribalism is not inherently bad, but it can lead to ideological thinking and sacred values that distort cognitive processing of putatively objective information in ways that affirm and strengthen the views and well-being of one’s ingroup (and that increase one’s own standing within one’s ingroup). Because of this shared evolutionary history of intergroup conflict, liberals and conservatives likely share the same underlying tribal psychology, which creates the potential for ideologically distorted information processing. Over the past several decades, social scientists have sedulously documented various tribal and ideological psychological tendencies on the political right, and more recent work has documented similar tendencies on the political left. We contend that these tribal tendencies and propensities can lead to ideologically distorted information processing in any group. And this ideological epistemology can become especially problematic for the pursuit of the truth when groups are ideologically homogenous and hold sacred values that might be contradicted by empirical inquiry. Evidence suggests that these conditions might hold for modern social science; therefore, we conclude by exploring potential ideologically driven distortions in the social sciences.
QoS-Oriented Adaptive User Association for NOMA in Visible Light Communications

In this paper, we propose a quality of service (QoS)-oriented adaptive virtual user association scheme for non-orthogonal multiple access (NOMA)- visible light communication (VLC) systems. Our schemes enables to surmount the throughput degradation caused by traditional synchronous NOMA multiplexing and the communication interruption due to low received QoS. Radio frequency configuration is proposed as a backup for VLC to ensure normal communication of users disconnecting from VLC, and the number of users participating in real-time association is adaptively updated. Orthogonal multiple access (OMA) is also incorporated with NOMA to further enhance the system performance. Numerical results demonstrate that compared with traditional NOMA and OMA methods, the proposed scheme could provide better network throughput and cumulative distribution function of user rate performance under perfect and imperfect successive interference cancellation in NOMA-VLC systems.

A New Way for Walén Test of Alfvénic Fluctuations in Solar Wind Streams via EEMD

Pure Alfvén waves at 1 au can be effectively identified by a Walén test of plasma and magnetic field observations. In this study, a new method, based on the Ensemble Empirical Mode Decomposition (EEMD) technique, is proposed for analyzing Alfvén fluctuations in two ways: (1) the Walén test relied on a time-dependent frame, which is extracted from the trend of differences between plasma and Alfvén velocity; and (2) a modified Walén test of the reconstructed Alfvénic and plasma velocity fluctuations by EEMD, after removing the high/low-frequency components irrelevant to Alfvénicity. Referencing the three validated methods mentioned in Chao et al., the same four cases in high-speed solar wind steams are tested by the EEMD method, considering Alfvénic parameters such as the Walén slope, the standard deviation ratio, the Alfvén ratio, the normalized cross helicity, the normalized residual energy, and the mean deviation relative to 1. The test results indicate that the first EEMD method can improve most Alfvénic parameters, since a time-varying velocity of the De Hoffmann–Teller frame is obtained from the process of self-adaptive data analysis, especially for complex cases with nonstationary and multiple background frames. The second EEMD method provides a kind of flexible testing to reconstruct the optimal fluctuations satisfied for the Walén relation, which achieves similar or even better results than normal prior methods based on bandpass filtering. We suggest that the EEMD method can be an alternative way to identify large-amplitude Alfvén waves in solar wind streams with single-satellite data.
A relational turbulence theory perspective on women’s grief following miscarriage

This study used relational turbulence theory to examine (a) how the relational impact of miscarriage corresponded with bereaved mothers’ grief responses and (b) the association between a partner’s supportive conversational behaviors and relationship qualities. The sample included 193 women who had experienced a miscarriage within the previous year. As predicted, relational uncertainty was positively associated with women’s negative appraisals of miscarriage; facilitation from a partner was positively associated with women’s negative emotions; bereaved mothers’ negative appraisals and negative emotional responses covaried; and a partner’s supportive conversational behaviors were positively associated with facilitation from a partner. Contrary to our predictions, interference from a partner was not associated with more intense negative emotions, and a partner’s supportive conversational behaviors were positively associated with relational uncertainty and interference from a partner. The discussion highlights the relational impact of miscarriage on bereaved mothers’ experiences of grief.
