The Impact of Internet Use on Residents’ Subjective Well-Being: An Empirical Analysis Based on National Data

Internet use has become an indispensable part of people’s daily lives, and the relationship between Internet use and residents’ subjective well-being is receiving increasing attention from researchers. However, the existing literature on the relationship between Internet use and residents’ subjective well-being is still controversial and inconclusive, and there has been relatively little discussion of the mechanisms by which Internet use affects well-being. On the basis of data from the China General Social Survey 2015 (CGSS2015), this paper provides an empirical analysis of the impact of Internet usage on residents’ subjective well-being. The study finds that while Internet use had no significant impact on the well-being of residents compared to non-use, frequency of Internet usage did significantly improve subjective well-being. On this basis, we tested the mechanisms by which Internet use affects residents’ well-being through the three channels of the personal income effect, the human capital effect and the social capital effect. The findings partially verify the hypothesis of the mediating effect of social capital between Internet use and residents’ subjective well- being, but do not verify the hypothesis of the moderating effect of personal income and human capital. Compared with previous studies, this paper is innovative in the following three ways: it uses the latest available representative national microdata, which is better able to reflect recent Internet usage and its impact on residents’ subjective well-being; on the basis of existing research on the impact of Internet usage on residents’ well-being, it analyzes the specific mechanisms through which Internet use affects well-being, using the moderating effect model and the mediating effect model to make up for the shortcomings of existing research on the impact mechanism; and it applies the Bioprobit model to deal with the potential endogeneity of key explanatory variables, using a variety of model estimation methods to obtain more robust estimation results.

Enhancing Pulse Productivity under Rice Based Production System Through Chickpea and Lentil Based Intercropping Systems in North East India

A field experiment was conducted during rainy (kharif) and winter (rabi) seasons of 2014-15, 2015-16 and 2016-17 at Imphal, Manipur, to study the performance of intercropping chickpea (Cicer arietinum L.) and lentil (Lens culinaris Medik.) with linseed (Linum usitatissimum L.) and Indian mustard [Brassica juncea (L.) czernj. and cosson] under 2 varying preceding kharif lowland rice (Oryza sativa L) crop durations and also to evaluate the system productivity and profitability. Planting of medium duration rice variety enhanced growth and yield of rabi crops resulting in increase in system productivity in terms of rice equivalent yield (REY) and production efficiency (PE) by 5.4 %, and 14.5%, respectively over planting of late duration rice variety. Seed and biological yields of chickpea, lentil, Indian mustard and linseed were higher in sole cropping than in intercropping systems. Indian mustard and linseed were found dominant and aggressive as compared to chickpea and lentil. Chickpea and Indian mustard intercropping under 4:2 ratio proved more remunerative and recorded higher yield advantage than either of chickpea and linseed or lentil and Indian mustard intercropping as judged by REY (9.7 tonnes/ha), crop productivity (39.9 kg/ha/ day) and net return (` 81,168/ha). Land equivalent ratio (LER) of chickpea with Indian mustard (1.10) remained at par with intercropping chickpea with linseed (1.17), however, lentil intercropped with Indian mustard had less than unity LER of 0.87.
Reliability Assessment of Microgrid-Integrated Electrical Distribution System

Due to the transition of traditional power system to smart structure, integration of renewable energy sources is of great importance. It is performed by using distributed generators and Micro grid. Integration of renewable sources is very useful for the reliability enhancement of distribution system as energy can be supplied locally at distributed level. Therefore, this chapter provides an overview of various reliability methods which are utilized for finding the impact of renewable energy generation on distribution system reliability assessment. These renewable energy sources are integrated in the distribution system at distributed and Micro grid level. Various characteristics of renewable energy sources are discussed to model them. A general problem of reliability assessment in terms of reliability indices is also discussed.
Evaluation of two mind and body methods’ effects on stress reactivity, alexithymia, and their consequences

Cette these a pour but d’evaluer et de comprendre les effets de deux methodes de regulation emotionnelle, la meditation de pleine conscience et le yoga sur les reactions au stress, l’alexithymie et les variables liees. Quarante participants en bonne sante ont ete repartis au hasard dans trois groupes, yoga, meditation et groupe controle. Les resultats montrent que 8 semaines de meditation (1 session par semaine avec un instructeur et 2 sessions de pratique personnelle) ameliorent significativement la capacite a etre centre sur le present moment et la concentration. Les 8 semaines de yoga ont ameliore de facon significative la variabilite de la frequence cardiaque (augmentation HF(n.u.), diminution LF(n.u.) et LF/HF). Nous n’avons toutefois pas mis en evidence d’effet d’interaction groupe X temps pour l’alexithymie. Une analyse qualitative a alors ete effectuee afin de mieux comprendre les processus derriere les changement obtenus par les interventions. Il semble que la meditation de pleine conscience soit l’intervention la plus efficace pour l’alexithymie. Les differences individuelles comme la personnalite, les attitudes, la confiance en l’efficacite de l’intervention aussi bien que le niveau d’activite physique sont des facteurs qu’il faudrait prendre en compte dans le choix de la methode la plus adaptee a un profil particulier. En depit des limites de cette etude due principalement au faible nombre de sujets dans les groupes, il semble que le yoga et la meditation sont des interventions efficaces pour la gestion du stress, et la meditation de pleine conscience le programme le plus adaptee pour l’alexithymie.

The Effect of Privatization on the Characteristics of Innovation

We investigate the role of privatization on the after-market dynamic of innovation. We hypothesize that privatized firms will focus on a narrower set of technologies as a response to increased pressure for profitability and short-term results, and that they engage in overseas collaboration more after privatization. Using a cross-country sample of privatized firms, we find strong evidence supporting these hypotheses. In particular, newly privatized firms seem to increase overseas collaboration and devote most of it to the more promising technologies. Importantly, the overseas collaboration in technological innovation is associated with greater firm performance, but only so after privatization.
Comparative Analysis of High Frequency Signal Injection Based Torque Estimation Methods for SPMSM, IPMSM and SynRM

Torque estimation in permanent magnet synchronous machines and synchronous reluctance machines is required in many applications. Torque produced by a permanent magnet synchronous machine depends on the permanent magnets’ flux and d q -axes inductances, whereas torque in synchronous reluctance machines depends on the d q -axes inductances. Consequently, precise knowledge of these parameters is required for proper torque estimation. The use of high frequency signal both for permanent magnets’ flux and d q -axes inductances estimation has been recently shown to be a viable option. This paper reviews the physical principles, implementation and performance of high-frequency signal injection based torque estimation for permanent magnet synchronous machines and synchronous reluctance machines.
Reset control and control allocation for high-precision motion systems

− In this chapter, we present a reset control approach to improve the transient performance of a PID-controlled motion system subject to Coulomb and viscous friction. A reset integrator is applied to circumvent the depletion and refilling process of a linear integrator when the solution overshoots the setpoint, thereby significantly reducing the settling time. Robustness for unknown static friction levels is obtained. The closed-loop system is formulated through a hybrid systems framework, within which stability is proven using a discontinuous Lyapunov-like function and a meagre-limsup invariance argument. The working principle of the proposed reset controller is analyzed in an experimental benchmark study on a high-precision positioning stage of an electron microscope.
Shifting agricultural practices to produce sustainable, low carbon intensity feedstocks for biofuel production

The carbon intensity (CI) of biofuel’s well-to-pump life cycle is calculated by life cycle analysis (LCA) to account for the energy/material inputs of the feedstock production and fuel conversion stages and the associated greenhouse gas (GHG) emissions during these stages. The LCA is used by the California Air Resources Board’s Low Carbon Fuel Standard (LCFS) program to calculate CI and monetary credits are issued based on the difference between a given fuel’s CI and a reference fuel’s CI. Through the Tier 2 certification program under which individual fuel production facilities can submit their own CIs with their facility input data, the LCFS has driven innovative technologies to biofuel conversion facilities, resulting in substantial reductions in GHG emissions as compared to the baseline gasoline or diesel. A similar approach can be taken to allow feedstock petition in the LCFS so that lower-CI feedstock can be rewarded. Here we examined the potential for various agronomic practices to improve the GHG profiles of corn ethanol by performing feedstock-level CI analysis for the Midwestern United States. Our system boundary covers GHG emissions from the cradle-to-farm-gate activities (i.e. farm input manufacturing and feedstock production), along with the potential impacts of soil organic carbon change during feedstock production. We conducted scenario-based CI analysis of ethanol, coupled with regionalized inventory data, for various farming practices to manage corn fields, and identified key parameters affecting cradle-to-farm-gate GHG emissions. The results demonstrate large spatial variations in CI of ethanol due to farm input use and land management practices. In particular, adopting conservation tillage, reducing nitrogen fertilizer use, and implementing cover crops has the potential to reduce GHG emissions per unit corn produced when compared to a baseline scenario of corn–soybean rotation. This work shows a large potential emission offset opportunity by allowing feedstock producers a path to Tier 2 petitions that reward low-CI feedstocks and further reduce biofuels’ CI. The prevalence of significant acreage that has not been optimized for CI suggests that policy changes that incentivize optimization of this parameter could provide significant additionality over current trends in farm efficiency and adoption of conservation practice.
WTA-WTP Disparity: The Role of Perceived Realism of the Valuation Setting

Based on a survey of more than 5,000 German households and a single-binary-choice experiment in which we randomly split the respondents into two groups, this article explores both households’ willingness to pay (WTP) for power supply security and their willingness to accept (WTA) compensation for a reduced security level. In accordance with numerous empirical studies, we find that the mean WTA value substantially exceeds the mean WTP value in our empirical example by a factor of 3.56. Yet, the WTA-WTP ratio decreases to 2.35 if respondents believe that the hypothetical valuation setting is likely to become true.
Indirect and adaptive test of analogue circuits based on preselected steady-state response measures

Alternate testing techniques have been progressively adopted as a promising solution due to their effectiveness against classical specification-based test methods. This work presents a built-in test system, which adaptively generates an indirect digital signature characterising the circuit under test, which is later used to diagnose the actual performances relying on a statistical dictionary-based diagnosis method. The system is composed of an integrated digital signature generator and a digital control and acquisition subsystem. The signature generator is based on a converter architecture, in which the analogue range can be adapted to the magnitude of the indirect measure using the well known information of the fault-free circuit. The digital subsystem controls the proposed architecture and stores the digital codes sent by the integrated digital signature generator. The digital signature generator has been designed and fabricated in an industrial 65 nm complementary metal–oxide–semiconductor technology from STMicroelectronics, whereas the digital control and acquisition subsystem have been prototyped in a field-programmable gate array. The fabricated system has been used to test a biquad filter affected by parametric variations. Successful experimental results are reported showing the capabilities of the proposed adaptive test system to diagnose circuit performances with discrepancies as low as 1% of the actual real value.
Graphene and other 2D materials: a multidisciplinary analysis to uncover the hidden potential as cancer theranostics

Cancer represents one of the main causes of death in the world; hence the development of more specific approaches for its diagnosis and treatment is urgently needed in clinical practice. Here we aim at providing a comprehensive review on the use of 2-dimensional materials (2DMs) in cancer theranostics. In particular, we focus on graphene-related materials (GRMs), graphene hybrids, and graphdiyne (GDY), as well as other emerging 2DMs, such as MXene, tungsten disulfide (WS2), molybdenum disulfide (MoS2), hexagonal boron nitride (h-BN), black phosphorus (BP), silicene, antimonene (AM), germanene, biotite (black mica), metal organic frameworks (MOFs), and others. The results reported in the scientific literature in the last ten years (>200 papers) are dissected here with respect to the wide variety of combinations of imaging methodologies and therapeutic approaches, including drug/gene delivery, photothermal/photodynamic therapy, sonodynamic therapy, and immunotherapy. We provide a unique multidisciplinary approach in discussing the literature, which also includes a detailed section on the characterization methods used to analyze the material properties, highlighting the merits and limitations of the different approaches. The aim of this review is to show the strong potential of 2DMs for use as cancer theranostics, as well as to highlight issues that prevent the clinical translation of these materials. Overall, we hope to shed light on the hidden potential of the vast panorama of new and emerging 2DMs as clinical cancer theranostics.
Evaluation of drug therapy problems among outpatient hypertensive and type-2-diabetic patients at a Tertiary Hospital, South-West Nigeria

Background: Health-related burden and poor outcomes due to drug therapy problems (DTPs) is a major concern in healthcare delivery especially in resource-poor countries.Objective: To evaluate extent and types of DTPs as well as disease-specific clinical parameters in outpatient hypertensive and type-2-diabetic (T2D) patients attending a tertiary hospital in Nigeria.Materials and Methods: This entailed questionnaire-guided interaction with 205-adult hypertensive and 198-T2D patients who were purposively enrolled, followed by a retrospective review of their medical records from September - November 2018. Domains of DTP explored included drug and dose selection, drug form, treatment duration, patients’ adherence and drug interactions. Data were summarised using descriptive statistics, while categorical variables were evaluated with Chi-square test at p drug interactions, 155 (36.7 %)>drug selection, 25 (5.9 %); while for hypertensive patients, the order was non-adherence [intentional, 156 (37.3 %); unintentional, 57 (13.6 %)]>drug interactions, 157 (37.6 %)>dose selection, 25 (6.0 %)>drug selection, 23 (5.5 %). A total of 133(65.5 %) hypertensive patients had good blood pressure (≤140/90 mmHg) control, while the mean glycosilated haemoglobin was 7.5 (SD=2.6 %). Conclusion: Extent of DTPs among participants is high, with non-adherence and drug interactions constituting the highest DTPs burden. There is generally a need for prescribers and pharmacists in particular to be wary of potential or actual DTPs during patient encounters, as this may ensure better therapeutic outcomes.Keywords: Drug therapy problems, Hypertensive and type-2-diabetic patients, Outpatient, Nigeria
Bayesian Model Weighting: The Many Faces of Model Averaging

Model averaging makes it possible to use multiple models for one modelling task, like predicting a certain quantity of interest. Several Bayesian approaches exist that all yield a weighted average of predictive distributions. However, often, they are not properly applied which can lead to false conclusions. In this study, we focus on Bayesian Model Selection (BMS) and Averaging (BMA), Pseudo-BMS/BMA and Bayesian Stacking. We want to foster their proper use by, first, clarifying their theoretical background and, second, contrasting their behaviours in an applied groundwater modelling task. We show that only Bayesian Stacking has the goal of model averaging for improved predictions by model combination. The other approaches pursue the quest of finding a single best model as the ultimate goal, and use model averaging only as a preliminary stage to prevent rash model choice. Improved predictions are thereby not guaranteed. In accordance with so-called M -settings that clarify the alleged relations between models and truth, we elicit which method is most promising.
Improved problem-solving skills of the student through cooperative problem-solving models related to fluid dynamic topic

Problem-solving skills (PSS) were needed to prepare for the working world. Based on a preliminary study at one of Senior High School in Banjaran West Java, the average score of student Problem-Solving Skills (PSS) was low. This study aims to determine the improvement of PSS of student after applied Cooperative Problem Solving (CPS) models on dynamic fluid. The research method used was a pre-experiment with one group pretest-posttest design. The subjects of this study were students of class XI Science 2 selected by purposive sampling technique amounted to 30 people. The student’s PSS was measured through an essay test and a supporting instrument in the form of student worksheets. The results showed that there was an increase of PSS of students with of 0.68 medium categories. Based on the paired sample t-test where tcount (12.24) > ttable (2.05) indicates that there was the influence of CPS models to improve PSS of students. The average results of the student worksheet analysis indicate that there was an increase student’s PSS at each meeting and the average value was categorized well. Thus, the CPS models can be used as an alternative learning model that can improve PSS of students on dynamic fluid.
The true axial shoulder projection: Diagnostic aid for acromioclavicular joint dislocation?

Introduction Acromioclavicular joint dislocations are common. Differentiating between horizontal and vertical instability is challenging, but possible to diagnose on axial radiographs. No clear consensus for axial radiograph parameters currently exists. We aim to establish a reproducible technique to assess whether an axial radiograph represents a true axial view of the shoulder. Methods One hundred CT scans of normal uninjured shoulders were examined using multiplanar reformatting to assess the distance between the anterior glenoid (reference line) and anterior-most aspect of the acromion in the axial plane. Measurements were repeated and performed by multiple observers to give of intra- and inter-observer reliability. Results The mean distance from the anterior acromion to the reference line was −2.6 mm (i.e. posteriorly placed) (SD = 5.8 mm, range −16.9–13.2 mm). Most (89%) of the measurements were between 9 and −9 mm to the reference line. Intra-observer reliability was high with Cronbach’s α measurement as 0.997. Inter-observer reliability gave a Cronbach’s α measurement of 0.959. Conclusion When the anterior aspect of the acromion lies within 10 mm either side of a line parallel to the scapula blade at the anterior aspect of the glenoid on an axial radiograph, it represents a true axial projection of the glenohumeral joint (GHJ).

Concurrent validity of the Movement Assessment Battery for Children Checklist-2

The aim of this study was to examine a) the concurrent validity of the Movement Assessment Battery for Children Checklist-2 (MABCC-2) within Greek population, and b) the educators effect on the concurrent validity of the MABCC-2. Seventy-three educators (23 pre-school teachers, 30 primary school teachers and 20 primary physical education teachers) participated in the study assessing 584 students (age range 5–12 years, 292 boys & 292 girls), covering the total of age range addressed by the MABCC-2. Students were assessed both by the MABCC-2 and the Movement Assessment Battery for Children2 motor test (MABC-2-T). Concurrent validity was investigated by measuring the level of agreement (Kappa coefficient) between the checklist and the motor test, as well as by calculating the sensitivity, specificity and accuracy rates. Results revealed a moderate value of agreement (k=.28), moderate sensitivity (50.6%) and acceptable specificity (80.7%). The type of educator displayed a significant effect on MABCC-2 concurrent validity rates. Best results were obtained for preschool and primary school teachers. The findings suggest that the exclusive use of the MABCC-2 may not be sufficient to identify children with motor difficulties in Greek school context. However, the rates of concurrent validity obtained in the present study are not unusual for checklists. In general, it was stressed by several researchers that motor assessment checklists for educators usually present low concurrent validity especially in populationbased samples.
