Abstract

Purpose

Food gives us essential nutrients to lead a healthy lifestyle but lately it has been found that many food products have become hazardous due to contamination and lead to many diseases. The rampant use of pesticides and chemical-based fertilizers in agriculture has, increased the productivity but at the same time they have created an alarming situation for the environment. The demand of the hour is to therefore to encourage organic farming and offer a better choice to consumers as well as save the environment. The purpose of this paper is to explore and understand the factors affecting perception of consumers on organic food products in Indian context.

Design/methodology/approach

The study used a structured survey of 150 respondents covering Delhi and the National Capital Region (NCR) of Ghaziabad, Noida and Faridabad (India). Exploratory research was used to know the variables from the literature that affect the perception of consumers regarding organic food. Descriptive research was used to understand the demographic profile of the organic food consumer’s. Conclusive research design was used to test the hypotheses based upon the motivating and inhibiting factor in the growth of organic food.

Findings

The data collected from the survey were analyzed using t-test, χ 2 test, factor analysis and multiple linear regression tests. Results indicated that the intention to purchase organic products was impacted by the consumer’s belief on the safety and health aspect of the product, trust and certification, information and availability and lifestyle and are hence drivers of growth. And certain impeding factors were identified like doubt in the professed quality of organic food, lack of awareness and price parity.

Social implications

There are enough evidences of fertile land being converted into wasteland because of use of agro- chemical-based fertilizers in farming. There are also enough incidents of polluted water (ground and surface) due to agrochemical-based farming. Heavy use of pesticides leads to adverse effect on the health of farmers also. There were many reports of farmers committing suicide because of debt due to heavy investment on pesticides and fertilizers. Organic farming is a win-win proposition for environment, farmers and consumer’s.

Originality/value

The study was an effort to understand awareness and perception of organic food consumers in urban India post-agriculture revolution. The result would help the organic food producing and marketing companies to understand the factors that influence the belief of consumers when they purchase organic food and henceforth they can formulate communication strategies and marketing policy based on consumer’s expectations.

Learning outcomes

Appreciating the role of process innovation in enabling growth; Understanding why replication is time consuming and not straight-forward; distinguishing formal and informal dimensions of coordination-mechanisms; Analyzing the differences in replication using template and principles.

Case overview/synopsis

Entrepreneurs desire to grow their businesses. They look for opportunities, in this case, when an opportunity came in year 2006, the entrepreneur successfully en-cashed. This lead to formation of a strategic business unit (SBU) that grew faster and also became role model. However the main SBU, for which the firm is known, continued past legacy. It is only when they found it difficult to grow, they decided to emulate. However, transition was not easy, it took much higher efforts. In the transformation, the older-SBU found that it is only inspiration, direction and fundamental principles that they can take from the newer-SBU. They have to fight their own battle and evolve solutions themselves. The older-SBU finally did succeed in the replication. The case experiences decision-making on template versus principle route to replication giving the participants enough exposure and thinking on the subject.

Abstract

Purpose

Recent investigations on magnetic properties of non-oriented (NO) steel sheets enhance the comprehension of the magnetic anisotropy behaviour of widely employed electrical sheets. The concept of energy/coenergy density can be employed to model these magnetic properties. However, it usually presents an implicit form which requires an iterative process. The purpose of this paper is to develop an analytical model to consider these magnetic properties with an explicit formulation in order to ease the computations.

Design/methodology/approach

From rotational measurements, the anhysteretic curves are interpolated in order to extract the magnetic energy density for different directions and amplitudes of the magnetic flux density. Furthermore, the analytical representation of this energy is suggested based on statistical distribution which aims to minimize the intrinsic energy of the material. The model is finally validated by comparing measured and computed values of the magnetic field strength.

Findings

The proposed model is based on an analytical formulation of the energy depending on the components of the magnetic flux density. This formulation is composed of three Gumbel distributions. Every functional parameters of energy density is formulated with only four parameters which are calculated by fitting the energy extracted from measurements. Finally, the proposed model is validated by comparing the computation and the measurements of 9

H

loci for NO steel sheets at 10 Hz. The proposed analytical model shows good agreements with an average relative error of 27 per cent.

Originality/value

The paper presents an original analytical method to model magnetic anisotropy for NO electrical sheets. With this analytical formulation, the determination of H does not require any iterative process as it is usually the case with this energy method coupled with implicit function. This method can be easily incorporated in finite element method since it does not require any extra iterative process.

Abstract

The Canadian mutual fund setting is unique in that two governance mechanisms – corporate and trust – coexist. This study empirically examines the impact of each mechanism on fund fees and performance. We find that corporate class funds charge higher fees but deliver superior fee-adjusted returns than trust funds. We then analyze the impact of various board characteristics on fees and performance for corporate class funds. We find that a board with smaller size, CEO duality, and a higher percentage of independent directors is more likely to charge lower fees. In addition, smaller boards are strongly associated with higher fee-adjusted performance. Our study supports agency theory over stewardship theory and provides valuable guidelines for Canadian investors and regulatory agencies.

This paper aims to describe the fabrication and characterization of current mirror-integrated microelectromechanical systems (MEMS)-based pressure sensor.

Abstract

Purpose

This paper aims to describe the fabrication and characterization of current mirror-integrated microelectromechanical systems (MEMS)-based pressure sensor.

Design/methodology/approach

The integrated pressure-sensing structure consists of three identical 100-µm long and 500-µm wide n-channel MOSFETs connected in a resistive loaded current mirror configuration. The input transistor of the mirror acts as a constant current source MOSFET and the output transistors are the stress sensing MOSFETs embedded near the fixed edge and at the center of a square silicon diaphragm to sense tensile and compressive stresses, respectively, developed under applied pressure. The current mirror circuit was fabricated using standard polysilicon gate complementary metal oxide semiconductor (CMOS) technology on the front side of the silicon wafer and the flexible pressure sensing square silicon diaphragm, with a length of 1,050 µm and width of 88 µm, was formed by bulk micromachining process using tetramethylammonium hydroxide solution on the backside of the wafer. The pressure is monitored by the acquisition of drain voltages of the pressure sensing MOSFETs placed near the fixed edge and at the center of the diaphragm.

Findings

The current mirror-integrated pressure sensor was successfully fabricated and tested using in-house developed pressure measurement system. The pressure sensitivity of the tested sensor was found to be approximately 0.3 mV/psi (or 44.6 mV/MPa) for pressure range of 0 to 100 psi. In addition, the pressure sensor was also simulated using Intellisuite MEMS Software and simulated pressure sensitivity of the sensor was found to be approximately 53.6 mV/MPa. The simulated and measured pressure sensitivities of the pressure sensor are in close agreement.

Originality/value

The work reported in this paper validates the use of MOSFETs connected in current mirror configuration for the measurement of tensile and compressive stresses developed in a silicon diaphragm under applied pressure. This current mirror readout circuitry integrated with MEMS pressure-sensing structure is new and fully compatible to standard CMOS processes and has a promising application in the development CMOS-MEMS-integrated smart sensors.
