This study investigates to what extent a working wife helped her family escape poverty and how this function developed during the great recession, based on analyses using the Survey of Income and Program Participation (SIPP) data. I use an extension of the standard Blinder-Oaxaca decomposition framework that decomposes the working wife's effect on the proportion of families below poverty. I found that wife's earnings reduced the average family poverty level by around 10 percentage points during the great recession but by over 30 percentage points for families with unemployed husbands.

The article presents new realizations of capacitance multiplier circuits, employing two voltage differencing transconductance amplifiers (VDTAs) and one capacitor without any passive resistors. The equivalent capacitance value of the proposed capacitance simulators can be achieved electronically by regulating the DC bias currents of VDTAs. All the proposed realizations do not require any critical component matching conditions. The lossless floating negative capacitor multiplier (NCM) circuit is studied in detail. The capacitive cancellation scheme and a quadrature sinusoidal oscillator circuit are included to demonstrate the effectiveness of the circuit. The effect of the VDTAs non-idealities and parasitic on the realized circuits is analysed. SPICE simulation results using TSMC 0.18 µm CMOS technology parameters are presented to reflect the workability of the proposed NCM. The simulation results are in excellent agreement with the theoretical calculation. In addition to these, a comparison with the previously reported circuits is summarized to confirm the superiority of the recommended NCM. [ABSTRACT FROM AUTHOR]

The popularity of mutual funds, which are necessarily portfolios, has been drawing more attention from the people of India over the last three decades. In a mutual fund, one can invest his or her money in the securities of different sectors traded mainly in the stock exchange markets to get expected return bearing tolerable risks. A mutual fund other than the passive mutual funds is directed by an active fund manager. The performance of a mutual fund depends on the shares and securities of different companies it contains and the fund manager's performance also. Risk and return can be measured based on different criteria. Before investment, one should select such a mutual fund that can fulfill his or her anticipation as much as possible within the risk–return skeleton. Therefore the selection of a mutual fund is rigorously a multicriteria decision making. This paper has considered five open‐ended, large‐cap, direct, suspended sales mutual funds for the research work. In the first stage, we have shortlisted the more crucial criteria comparatively from a list of criteria with the help of the Fuzzy Analytic Hierarchy Process. In the second stage, we have applied the Pythagorean fuzzy Gray Relation Analysis approach to determine the weights of shortlisted criteria as well as the rank of those mutual funds. Finally, a comparison has been drawn between the present model and the Pythagorean fuzzy Interactive Multicriteria Decision‐Making model, to show the effectiveness of the present model.

In this contribution, nine new Grounded Inductance Simulators (GISs) using a single Multiple-Output Current Controlled Current Conveyor Transconductance Amplifier (MO-CCCCTA) and one grounded capacitor are proposed. Among them, two are lossless types and seven are lossy types. The use of a single grounded capacitor makes the circuits suitable for fabrication. All the proposed circuits are electronically tunable through the bias currents of MO-CCCCTA. Furthermore, no component matching conditions are needed for realizing them. The designed circuits are verified through PSPICE simulator with ± 0.9 V power supply. The simulation results show that for all the proposed circuits: maximum operating frequencies are about 12 MHz, power dissipation is less than 0.784 mW, Total Harmonic Distortions (THDs) are under 8.09%, and maximum output voltage noise at 1 MHz frequency is 14.094 nV/vHz. To exhibit the workability of the proposed circuits, they are used to design band-pass, low-pass filter, parallel RLC resonator, and parasitic inductance cancelator. [ABSTRACT FROM AUTHOR]

The objective of this study is to present four new universal biquad filters, two voltage-mode multi-input-single-output (MISO), and two current-mode single-input-multi-output (SIMO). The filters employ one voltage differencing current conveyor (VDCC) as an active element and two capacitors along with two resistors as passive elements. All the five filter responses, i.e., high-pass, low-pass, band-pass, band-stop, and all-pass responses, are obtained from the same circuit topology. Moreover, the pole frequency and quality factor are independently tunable. Additionally, they do not require any double/inverted input signals for response realization. Furthermore, they enjoy low active and passive sensitivities. Various regular analyses support the design ideas. The functionality of the presented filters are tested by PSPICE simulations using TSMC 0.18 µm technology parameters with ± 0.9 V supply voltage. The circuits are also justified experimentally by creating the VDCC block using commercially available OPA860 ICs. The experimental and simulation results agree well with the theoretically predicted results. [ABSTRACT FROM AUTHOR]
