This paper examines the prices of fishery products (an important source of protein for the poor) and drivers of their inter-regional variations in India, where fishery is a critical sector. By explaining regional price differences, we make an attempt to derive policy implications as to how fish price inflation can be controlled.

The paper is primarily based on secondary data provided by the Ministry of Agriculture, Government of India. In the absence of data on inter-regional trade, appropriate indicators are constructed using the gravity model to capture supply side factors that may influence regional price differences. Pooled regressions are carried out for a representative marine and an aquaculture fish variety separately for the period 2011 to 2017.

After controlling for income levels, it is found that marine fish prices can be reduced by improving intra-state transport infrastructure. For reducing the price of aquacultures, it is shown that it is imperative to reduce the distance between producers and consumers.

The study is limited by the availability of data on interstate trade and consumption of fish and has only used prices of representative fish varieties instead of average marine and aquaculture fish prices.

This paper considers trade and value chain based business theories to explain regional price differences. It analyzes the drivers of relative price differences and suggests measures to control them using a gravity model of trade.

The purpose of this paper is to understand the status of a class of non‐permanent labour in the globalised era in India.

To understand this the paper uses both secondary level information and primary data collected through a survey. Secondary level data are analysed using a panel data model. Here, the hypothesis is: contribution of contract labour to production is greater than that of the regular employees. The primary level survey is conducted to know whether they are exploited due to their non‐permanent stature.

It is observed from secondary data analysis that the hypothesis is not rejected. Contract labour makes a significant contribution to production, while the regular employees do not. Primary survey also shows that they are exploited in many ways including through non‐payment of minimum wages.

The paper indicates that, while regulations are in place, they are abused and hence it is the implementation part on which government needs to focus.

Analysis shows how rationalization of employment does not take place due to labour regulations for the regular employees. It also brings to light through primary survey various lacunae in the implementation of the Contract Labour Act. Since survey of such labour class is difficult there are limited studies in this field.

The purpose of this paper is to explore the phenomenon of burnout during early career among knowledge workers in information technology (IT) services industry in India.

The grounded theory research design was used to explore the research phenomenon. The study was based on the analysis of 43 in-depth interviews from the employees, managers and human resource professionals in IT services industry in India. Purposeful and theoretical sampling designs were used to locate the participants for the study. Grounded theory analytical procedures – open, axial and selective coding – were used to analyze and interpret the interview narratives. Atlas ti version 5.0. was used for qualitative data analysis.

The analysis of the interviews with the young knowledge workers reveal the following as the reasons for their burnout during early career: poor integration with the job and the organization at large, underemployment, stressful job and exhausting work environment, fear and insecurity of replacement of talent and downsizing. Strategies are discussed to deal with burnout situations among the young knowledge workers for individual and organizational well-being.

The findings of the study are applicable to organizations such as the IT services industry and thus the research outcome cannot be generalized. The study includes lived experiences of employees only during their early career.

The findings are relevant and useful in the practice domain as they are grounded in field reality. It provides directions for managerial and organizational practices in preventing burnout in early career among knowledge workers.

The paper is original and the present study is among the first attempts to investigate the nature of burnout through qualitative inquiry.

This article aims to study the tensile properties of a functionally graded composite structure with Al–18wt%Si alloy as the matrix material and silicon carbide (SiC) particles as the reinforcing element. More specifically, the study's primary objective is to optimize the composition of the material elements using a robust statistical approach.

In this research, the composite material is fabricated using a combination of stir casting and the centrifugal casting technique. Moreover, the test specimen required to study the tensile strength are prepared according to the ASTM (American Society for Testing and Materials) standards. Eventually, optimal composition to maximize the tensile property of the material is determined using the mixture design approach.

The investigation results imply that the addition of the SiC plays a crucial role in increasing the tensile strength of the composite. The optical microstructural images of the composite show the adequate distribution of the reinforcing particles with the matrix. The proposed regression model shows better predictability of tensile strength. In addition, the methodology aids in optimizing the mixture component values to maximize the tensile strength of the produced functionally graded composite structure.

Little work has been reported so far where a hypereutectic Al–Si alloy is considered the matrix material to produce the composite structure. The article attempts to make a composite structure by using a combination of stir casting and centrifugal casting. Furthermore, it employs the mixture design to optimize the composition and predict the model of the study, which is one of a kind in the field of material science.

Watermarking technique is one of the significant methods in which carrier signal hides digital information in the form of watermark to prevent the authenticity of the stakeholders by manipulating different coefficients as watermark in time and frequency domain to sustain trade-off in performance parameters. One challenging component among others is to maintain the robustness, to limit perceptibility with embedding information. Transform domain is more popular to achieve the required results in color image watermarking. Variants of complex Hadamard transform (CHT) have been applied for gray image watermarking, and it has been proved that it has better performance than other orthogonal transforms. This paper is aimed at analyzing the performance of spatio-chromatic complex Hadamard transform (Sp-CHT) that is proposed as an application of color image watermarking in sequency domain (SD).

In this paper, color image watermarking technique is designed and implemented in SD using spatio-chromatic – conjugate symmetric sequency – ordered CHT. The color of a pixel is represented as complex number a*+jb*, where a* and b* are chromatic components of International Commission on Illumination (CIE) La*b* color space. The embedded watermark is almost transparent to human eye although robust against common signal processing attacks.

Based on the results, bit error rate (BER) and peak signal to noise ratio are measured and discussed in comparison of CIE La*b* and hue, saturation and value color model with spatio-chromatic discrete Fourier transform (Sp-DFT), and results are also analyzed with other discrete orthogonal transforms. It is observed from BER that Sp-CHT has 8%–12% better performance than Sp-DFT. Structural similarity index has been measured at different watermark strength and it is observed that presented transform performs better than other transforms.

This work presents the details and comparative analysis of two orthogonal transforms as color image watermarking application using MATLAB software. A finding from this study demonstrates that the Complex Hadamard transform is the competent candidate that can be replaced with DFT in many signal processing applications.
