Revealing the reality behind consumers’ participation in WEEE treatment schemes: a mixed method approach

With the enormous population growth and the ever-increasing use of various electronic devices in modern life, the proper disposal of the “Waste Electrical and Electronic Equipment” (WEEE) has been of paramount importance. The pervasive use of social media by customers has made governments and businesses use these platforms as a rich source of data to extract intelligence on consumer opinions. However, some scholars doubt the sufficiency of social media data concerning the design of a comprehensive list containing all influential factors on consumer behavior toward the proper treatment of WEEE. Thus, a mixed method of quantitative (by analyzing about 2,500,000 tweets from Twitter) and qualitative approaches (i.e. a literature thematic analysis followed by a three-phased Delphi method) has been adopted. Due to consumers’ different behavior based on their local status, the experts have been split into two different panels from developed and developing countries. They have also been provided with the findings from the literature along with the results from Twitter data analysis. The findings have revealed that economic incentives play a pivotal role in both categories. People in developing countries usually have concerns regarding socio-economic and socio-political issues, while in developed nations higher levels of influential factors exist, including proximity, suitability and ease of access, and so forth. The truth is that in order to have a green and pollution-free world, the whole world, whether developed or developing, must take joint steps to create public welfare, peace of mind and world peace. Otherwise, unilateral actions of countries will not have their desired effectiveness.
Design of sensitivity and round-off noise optimal state-space discrete systems

A previously defined sensitivity measure for state-space realizations is used, and the attainable minimum value and its necessary and sufficient conditions are given. An explicit optimization procedure which evaluates the complete class of realizations with minimum sensitivity is proposed. Conditions for minimizing the sensitivity under an 1, dynamic range constraint are established and an explicit method for obtaining this minimum is given. Since the relation between this sensitivity measure and the noise power gain for I, scaled digital filters can be given, and since the main part of the optimization can be carried out without taking into account the dynamic range constraint, a simple procedure for simultaneous minimization of sensitivity and round-off noise is obtained. A numerical example is given to exemplify the computational procedure.
Safer by design: Building a collaborative, integrated and evidence-based framework to inform the regulation and mitigation of gambling product risk

Evidence suggests that harms may result from gambling participation as a result of a complex interaction between individual differences among consumers, environmental factors, and the characteristics of the gambling product. The latter of these factors, broadly referred to in this paper as product risk, has received increased policy attention in recent years. Product-focussed approaches to harm reduction, however, are under-developed relative to other forms of player protection and likely reflects the limitations of existing evidence and relative complexity of the topic. In this position paper, we define and explain the concept of product risk and consider what is currently known regarding the link between gambling products and harm. The paper describes the present barriers to develop effective product risk regulation and harm mitigation strategies. These include the competing interests of stakeholders, limited collaboration and information sharing, clear roles, responsibilities and leadership and a lack of integrated evidence-informed approaches. In response to these challenges, we propose adopting a framework comprised of a series of principles to progress this contested area of policy. The framework encourages better collaboration and communication between stakeholders; the accelerated production of valid and reliable evidence; a strategic alignment of stakeholder activity; and, more effective and efficient approaches to assessing and mitigating product risk.
Determination of Pile Damage by Top Measurements

Measurements of force and acceleration at the pile top during driving can be used to detect the presence of damage at points along the pile below the ground surface. Analytical considerations based on one-dimensional wavemechanics are discussed, and a method is derived to place a quantitative measure on the degree of damage. Actual field measurements on damaged piles are presented.

Gender and wealth in the super rich: asset differences in top wealth households in the United States, 1989–2019

Wealth inequality is extreme and growing in the United States, and researchers have begun to explore the factors that are associated with membership in the top one percent of net worth owners. We contribute to this important literature by examining the association between gender and net worth in the U.S. super-rich. We propose that unmarried women, unmarried men, and married couples in the one percent are likely to have different levels of net worth and distinct patterns of asset holdings that reflect gender differences in income and saving, the household division of labor, work, and demographics. We use data from the 1989–2019 U.S. Survey of Consumer Finances (SCF), a unique data set that contains a high-income, high-wealth sample designed to accurately represent wealthy households. We find modest differences in total net worth among unmarried women, unmarried men, and married couples with unmarried women owning slightly less net worth than either unmarried men or married couples. We also find that unmarried women hold a lower percentage of their net worth in business assets and a higher percentage of their assets as trust accounts compared to unmarried men and married couples. Our findings contribute to the literature that explores the wealth of the super-rich and highlight the role that gender plays in these families. Our results also build on research on the role that business assets and trusts play in wealthy families and suggest that women may be dependent on others for access to the super-rich.
Relationship between Wood Traits and Sound Frequency at Different Pitch Levels of Talking Drums (Gangan) Manufactured from Aningeria robusta Wood

Wood is a unique material for making musical instruments and is used to make West African talking drums, whose pitch can be regulated depending upon how the player strikes the head of drum and changes its tension. Additionally, talking drum manufacturers have certain wood preferences, and in the absence of preferred species, they use supposedly unsuitable woods. Therefore, there is a need to examine wood traits in relation to the pitch of a talking drum. This study was designed to determine the existing relationship between selected wood traits and the frequency of talking drums made from A. robusta wood. Three A. robusta trees were obtained from Onigambari Forest Reserve. From each tree, three bolts of 50 cm in length were obtained from the base, middle, and top of the tree to determine selected properties (moisture content (MC), wood basic density (WBD), modulus of elasticity (MOE), modulus of rupture (MOR), and manufacturing of talking drums). A spectrum analyzer was used to analyze the sound frequency of the talking drums at three pitch levels (high, medium, low). A completely randomized block design was used and the data obtained was analyzed using descriptive statistics, ANOVA, and correlation analyses at α 0.05. Sound frequency was not significant along sampling height, but was significant at pitch levels. Additionally, the correlation analysis between wood traits and sound frequency was not significant. Thus, wood cannot be recommended for talking drums’ optimal acoustic performance based on wood traits alone.
The Effect of Incident Wake Conditions on the Mean Heat Transfer of an Airfoil

The flow phenomena of wakes shed by upstream blade rows is a well–known problem in turbomachinery which influences blade forces, vibrations, losses and heat transfer. With respect to the heat load to turbine blades this problem becomes even more complex because of the interaction between wake, potential flow and the boundary layer along the surface of the airfoil.Experimentally evaluated mean heat-transfer coefficients obtained under different unsteady initial conditions are reported. The heat–transfer measurements have been carried out in the cascade test facility at the ITS in Karlsruhe using a rotating bar wake generator placed upstream of the cascade to simulate the wake passing process. The variation of the wake parameters includes different wake passing frequencies, cascade inlet Reynolds numbers and wake inclination angles. In addition, the relevant parameters of the unsteady wake have been measured by means of a fixed hot–wire anemometer using the ensemble average technique. The results are compared to those from the literature for the wake of a cylinder in cross–flow. They also serve as experimental base for parallel theoretical analyses.Copyright © 1990 by ASME
Beam Loss Simulations During Beam Dumping in Heps

The High Energy Photon Source (HEPS) is a 6 GeV storage ring light source under construction in China. Several collimators installed in the vacuum chamber will be used as beam dump in the storage ring operation. Preliminary simulations showed that the temperature rise caused by the beam power deposited on the collimators will far exceed the melting point of the collimator material. In order to cure this problem, special kickers are proposed to be installed in the ring to modulate the beam during beam dumping, thereby increasing the size of the beam hit on the collimators. In this article, some simulation results of the density of particles on the collimators during beam dumping for different HEPS lattice and different kicker parameters are shown.
Synthesis and characterization of nanoscale composite particles formed by 2D layers of Cu-Fe sulfide and Mg-based hydroxide

Two-dimensional phenomena are attracting enormous interest at present and the search for novel 2D materials is very challenging. We propose here the layered material valleriite composed of altering atomic sheets of Cu-Fe sulfide and Mg-based hydroxide synthesized via a simple hydrothermal pathway as particles of 50-200 nm in the lateral size and 10-20 nm thick. The solid products and aqueous colloids prepared with various precursor ratios were examined using XRD, TEM, EDS, X-ray photoelectron spectroscopy (XPS), reflection electron energy loss spectroscopy (REELS), Raman, Mössbauer, UV-vis-NIR spectroscopies, magnetic, dynamic light scattering, zeta potential measurements. The material properties are largely determined by the narrow-gap (less than 0.5 eV) sulfide layers containing Cu+ and Fe3+ cations, monosulfide and minor polysulfide anions but are strongly affected by the hydroxide counterparts. Particularly, Fe distribution between sulfide (55-90%) and magnesium hydroxide layers is controlled through insertion of Al into the hydroxide part and by Cr and Co dopants entering both layers. Room-temperature Mössbauer signals of paramagnetic Fe3+ transformed to several Zeeman sextets with hyperfine magnetic fields up to 500 kOe in the sulfide layers at 4 K. Paramagnetic or more complicated characters were observed for valleriites with higher and lower Fe concentrations in hydroxide sheets, respectively. Valleriite colloids showed negative zeta potentials, suggesting negative electric charging of the hydroxide sheets, and optical absorption maxima between 500 nm and 700 nm, also depended on the Fe distribution. The last features observed also in the REELS spectra may be due to localized surface plasmon or, more likely, quasi-static dielectric resonance. The tunable composition, electronic, magnetic, optic and surface properties highlight valleriites as a rich platform for novel 2D composites promising for numerous applications.
Sole and Sequential Application of Herbicide and Straw Mulch on Weed Growth and Productivity of Direct Seeded Rainfed Rice (Oryza Sativa L.)

The sole and sequential application of herbicide and straw mulch on weed growth and productivity of rainfed direct seeded rice, were studied with 12 treatments during kharif 2019. Results showed that the application of oxadiargyl fb rice straw mulch @ 6 t/ha registered significantly the lowest weed density and dry weight at 60 DAS; however, it was statistically at par with oxadiargyl fb hand weeding. Weed free check produced the highest grain yield (3.05 t/ha) which was at par with the sequential application of oxadiargyl fb rice straw mulch @ 6 t/ha (2.99 t/ha) and oxadiargyl fb rice hand weeding (2.90 t/ha). Application of oxadiargyl fb rice straw mulch @ 6 t/ha fetched the maximum net return of Rs. 17528/- per ha and return per rupee invested of 1.52. Application of oxadiargyl fb rice straw mulch @ 6 t/ha could be recommended for managing complex weed flora, higher productivity and greater profit in rainfed direct seeded rice cultivation.

Meta-Frontier Analysis of Disclosing Sustainable Development Information: Evidence from China’s AI Industry

China currently adopts voluntary principles to disclose sustainable development information, and so considerable numbers of listed companies have chosen not to disclose such information. Since disclosure and non-disclosure groups face different production opportunities, this research uses the meta-frontier framework to completely analyze sustainable development practices of China’s artificial intelligence (AI) industry. Empirical results show that the disclosure group outperforms the non-disclosure group in operating scales, efficiencies, and technologies, while the superior efficiency of state-owned enterprises (SOEs) comes entirely from the non-disclosure group. Hence, the government should mandate or actively encourage capable corporations, especially SOEs, to disclose sustainable development information, as doing so improves the overall sustainable development of society and also enhances these firms’ performance. Finally, the authority can formulate a nationwide disclosure policy regardless of the existing differences in regional development.
Utilization of an active-clamp circuit to achieve soft switching in flyback converters

Flyback derived topologies are attractive because of their relative simplicity when compared with other topologies used in low power applications. Incorporation of active-clamp circuitry into the flyback topology serves to recycle transformer leakage energy while minimizing switch voltage stress. The addition of the active-clamp circuit also provides a mechanism for achieving zero-voltage-switching (ZVS) of both the main and auxiliary-switches. ZVS also limits the turn-off di/dt of the output rectifier, reducing rectifier switching losses and switching noise due to diode reverse recovery. <<ETX>>
Space Planning Method for Multistory Building Construction

This paper presents a space planning method for multistory building construction. Current formal space planning in practice is limited to site layout and logistics, where space is needed for activities for extended periods of time. The space planning needed to sequence activities inside a building under construction is often neglected. The proposed space planning method is a manual method that provides a logical order and priority for space planning decisions. This helps a construction planner to: (1) identify the specific spaces needed for activities; (2) define locations for these spaces on building floors; (3) develop a sequence of work that defines the order spaces are occupied; and (4) identify potential spatial conflicts. Detail is added to the plan as needed. Through evaluation of 74 activities on four case study projects, the proposed method was found to be an accurate representation of the planning needed in multistory building construction. Two applications of the planning method identified interference problems before they occurred in the field. This space planning method offers construction managers a useful technique to develop efficient interior sequences that minimize interference and work space congestion.
Adaptive ground fault protection schemes for turbogenerator based on third harmonic voltages

Equivalent circuits based on the actual connection of coil-groups of generators are used to study the characteristics of various generator stator ground fault protection schemes presented in the literature. The evaluation and the comparison of the characteristics of those schemes are given by means of protection coverage-critical resistance curves. Although these schemes are successful in practice, they suffer the disadvantage of low sensitivity, which is strongly related to generator operating conditions. To overcome this disadvantage, two adaptive stator ground fault protection schemes based on digital techniques are developed. Compared to conventional third-harmonic voltage schemes, they can automatically track the change of generator operating conditions before a ground fault occurs. Test results from a digital simulation show that they can keep high sensitivity during all operating conditions. >
SOEPpapers on Multidisciplinary Panel Data Research

In this paper, we use data from the German Socio-Economic Panel (SOEP) in the 1997-2009 period for a large sample of migrants from 84 countries in order to develop an empirical model for the propensity by migrants to remit. Our model takes into full account the intertemporal aspects of the problem, which has been ignored by a large part of the applied literature, despite its theoretical and empirical importance. We find that most results already established in the empirical literature are confirmed; however, the intertemporal nature of the remittance behaviour emerges very clearly, giving rise to individual patterns which are difficult to synthesize by a simple description. Building on our framework, we find also support for theoretical models which predict different remittance time paths between return and permanent migrants.

Molecular features of Probopyrus sp. (Isopoda: Bopyridae) from Brazilian Amazonia and the parasitism of inland populations of Macrobrachium amazonicum (Decapoda: Palaemonidae)

Abstract Abstract Bopyrid isopods of the genus Probopyrus are well-known parasites of freshwater prawns of the genus Macrobrachium. The parasitism of coastal populations of Macrobrachium amazonicum by Probopyrus bithynis, for example, has been documented since the late 1980s. Despite this, molecular data on different populations are not available for any Probopyrus species. The present study is the first to describe Probopyrus populations from distinct regions of the Amazon basin based on sequences of two genes, the mitochondrial cytochrome oxidase C subunit I (COI) and the nuclear 18S ribosomal DNA (18S rDNA) gene. The analyses indicated the presence of two Probopyrus species, each parasitizing either the coastal or the inland populations of M. amazonicum. The results indicated the potential use of the COI barcode for the identification of Probopyrus species. We discuss the potential implications of the findings for the taxonomy of Probopyrus bithynis and other species of the genus Probopyrus.
THE EFFECT OF WATER SHORTAGE AT DIFFERENT STAGES OF FRUIT GROWTH ON THE YIELD AND FRUIT QUALITY IN "DESERT RED" PEACH TREES

This study was carried out during two successive growing seasons 2019 and 2020 on nine years old "Desert Red" peach trees (Prunus Persica L. Batsch) budded on Nemaguard rootstock. spaced at 4×4 m. trained to an open –vase system and grown in private orchard located at sedy Salem district, Kafrelsheikh Governorate. Subjected to Trees were horticulture practices usually, done in this region. The depth of water table is about 140-160 cm. the orchard soil is classified as clay. Egypt to study the effect of water shortage at different growth stages on some vegetative growth parameters, yield and fruit quality of " Desert Red " peach trees. The obtained data showed that, the highest mean values for studied vegetative growth parameters such as shoot length, shoot diameter, leaf area and specific leaf weight, yield (kg/tree – ton/fed.), and some fruit characters (fruit weight, fruit size, fruit length, fruit diameter and fruit shape) were recorded under control treatment (conventional irrigation). Meanwhile, vegetative growth parameters recorded the lowest values under T6 treatment, while the lowest values yield were recorded under T5. Fruit weight, fruit size, fruit length treatment, while the lowest values of yield were recorded under T5. Fruit weight, fruit size, fruit length and fruit diameter recorded the least values with T7 treatment. Concerning, productivity of irrigation water (PIW), whereas the highest values were obtained by T6 treatment, T5 treatment gave the lowest values. Fruit firmness, TSS and anthocyanin content in fruit peel of " Desert Red " peach trees were significantly affected by irrigation treatments, where, T7 treatment recorded the highest values for measured fruit firmness and TSS, while T6 treatment recorded the highest values for anthocyanin. The lowest values for measured fruit firmness, TSS and anthocyanin content were found under control condition (standard irrigation). Hence, we can recommend peach growers to apply T3 Treatment (10.186 m3/tree/year = 2678.92 m3/fed./year) to save 25%of irrigation water, as well as, to obtain about the same yield of control trees.
