Sentiment analysis of financial news articles using performance indicators

Srikumar Krishnamoorthy

Knowledge and Information Systems

Mining financial text documents and understanding the sentiments of individual investors, institutions and markets is an important and challenging problem in the literature. Current approaches to mine sentiments from financial texts largely rely on domain-specific dictionaries. However, dictionary-based methods often fail to accurately predict the polarity of financial texts. This paper aims to improve the state-of-the-art and introduces a novel sentiment analysis approach that employs the concept of financial and non-financial performance indicators. It presents an association rule mining-based hierarchical sentiment classifier model to predict the polarity of financial texts as positive, neutral or negative. The performance of the proposed model is evaluated on a benchmark financial dataset. The model is also compared against other state-of-the-art dictionary and machine learning-based approaches and the results are found to be quite promising. The novel use of performance indicators for financial sentiment analysis offers interesting and useful insights.

Replicating small farms, prosperous farmers in India: Lessons for policy and practice

Sukhpal Singh

Journal of Agribusiness Marketing

Small farm and small farmer viability has been a constant policy concern in India given its smallholder-dominated agriculture. Though there are different definitions of small farm in the literature, depending on local context, the term “smallholder” is a relative one in that it refers to the limited resource endowments of such farmers relative to those of other farmers in the sector in each local context. The Indian small farmers are in a state of agrarian distress, and the farmers’ quest for earning enough from a small farm continues. It is in this context of academic and policy discourse that this article makes evidence-based policy and practical recommendations for replicating the Small Farmer, Prosperous Farmer (SFPF) models of agricultural development in India based on empirical case studies of 35 small (who were just 2 hectares or smaller farm operators) and prosperous farmers (earning at least one lakh (0.1 million)Indian rupees per acre per year) across three states of India— Punjab, Gujarat, and Maharashtra. Major objectives of the study carried out in 2012 were as follows: document profiles of SFPFs in terms of their resources, costs, and profits; provide evidence of success (in terms of net income and prosperity) given small holdings; identify major factors in prosperity/success—personal, institutional, and social; and understand the role of policy and business environment, if any; and infer on possibilities of replicability of SFPF success given the other contextual factors in other regions. The study identifies sources of success and policy relevance of such factors for making inclusive agricultural development possible.

How inclusive and effective are farm machinery rental services in India? Case Studies from Punjab

Sukhpal Singh

Indian Journal of Agricultural Economics

Increasing cost of cultivation in most parts of India has led to the realisation that mechanisation of farm operations is one of the ways to tackle it as mechanical solutions are more efficient as well as cost effective compared with human labour based activities in most situations. However, given small farm dominance of Indian agriculture, it is not possible and viable for small farmers to own farm machinery and equipment for its use. Therefore, what they need is access to it, and not ownership. This has led to a new phenomenon of custom rental services of farm machinery and equipment in many parts of India by a range of players like co-operatives, private entrepreneurs, organised sector players and even producer companies. In this context of changing landscape of farm mechanisation, the paper examines the small holder inclusiveness of agro machinery rental service channels and the nature and the level of their effectiveness in helping the farmers access better services. It compares the performance of co-operative, private organised and local informal service providers in Punjab and identifies major issues and challenges in delivery of such services across types of farmers and examines the possible policy and enabling provisions to promote cost and quality effective custom rentals of farm machinery in India.

Gendered BoP hygiene markets in rural India: A case study of social entrepreneurship and social innovation

Sukhpal Singh

The Hong Kong Journal of Social Work

Water scarcity and non-existent or poor sanitation have special implications for the poor in a rural context of a developing country such as India, especially in the case of women due to their personal hygiene needs. The penetration of sanitary napkins is very low in Indian villages for reasons such as the high cost of branded napkins, availability, and cultural barriers. Over 88% of rural women use unhygienic alternatives during menstruation, with 77% using a piece of old cloth and many others nothing at all. These practices lead to a deterioration in health of the mother as well as the child and, sometimes, the death of the mother. Furthermore, a large proportion of girls in India do not go to school during their menstruation period, for an average of 4–5 days every month, and at least 23% of girls drop out of school when they start menstruating. Adult women cut down on their productive day-to-day activities. Menstruating lower-income women also have to follow certain social exclusion norms and treat it as a purely private matter as it is considered a social taboo. The access to personal reproductive hygiene products and services thus becomes indispensable in terms of addressing hygiene and sanitation needs. Furthermore, this is more of a developmental/social venture rather than just pure rural marketing. This paper examines the issue from a social enterprise and social innovation perspective in order to understand the issues involved in changing the situation. It examines the case of a social venture in India (Goonj) which has attempted to deal with this market in terms of its approach, product design, market creation, performance, issues faced, and impact made. The paper attempts to infer lessons for making social entrepreneurship and social innovations work in developing country health and hygiene contexts in the form of a Bottom of Pyramid (BoP) market solution.

Tenancy reforms: A critique of NITI Aayog’s Model Law

Sukhpal Singh

Economic and Political Weekly: A Journal of Current Economics and Political Affairs

There is no doubt that the agricultural land leasing laws in India need to be amended to make land leasing legal and easier. The Niti Aayog report (2016) proposes a formal model law on land leasing. Critically examining the logic for liberalisation of land leasing laws, the limitations of the model lease agreement are brought out. It is argued that the model law ignores the diversity and dynamics of leasing arrangements in India and the socio-economic implications of the realities of tenancy practices.

Case-Optimal Movement Plan of rice in the state of Andhra Pradesh in India

Sundaravalli Narayanaswami and N. Ravichandran

Informs Transactions on Education

The case discusses an optimal movement plan for food grains (rice) by a state sponsored agency, the Food Corporation of India (FCI) in the State of Andhra Pradesh in India. There are five resource locations and eleven demand locations in this distribution network. Resource capacity and demand requirement for the three product (rice) variants at each location are known. There is no storage capacity restriction either in the demand or source location. Information related to rail network, its connectivity, distance in kilometers between origin-destination pairs, cost of transportation per tonne of food grain by rail or road are known. The primary issue is to develop a monthly movement plan to minimize the overall transportation costs subject to meeting the demand-supply restrictions. The total supply available for distribution and the total requirement at various locations are both equal at the product variant and aggregate level. The secondary issue is to develop an alternative movement plan to fulfil the demand requirements at a location, Karimnagar, which does not have a direct rail connection. Few plans are proposed to resolve the issues; the case encourages analysis of the problem situation and evaluation of the alternate resolution plans.

Convergence or Divergence: The impact of globalization on employee relations in India and China

Jatinder Kumar Jha and Biju Varkkey

International Journal of Employment Studies

This paper explores the underlying principles of employee relations and the pattern of their evolution in India and China, in the context of globalisation. Globalisation has deeply influenced the way economies function and altered the national patterns of employee relations. Using evidences from available extant literature, we mapped the approaches taken by both India and China to highlight the impact of globalisation on employee relations and found that competition, followed by globalisation, and changes in the trade union structures, have prompted the introduction of the 'human' element to employee relations practices, particularly at the enterprise level; besides, a lucid convergence in employee relations patterns is also witnessed, alongside some divergences in the approaches. The points of convergence include the introduction of the human element in employee relations, labour flexibility, reduction in union membership and increased focus on individual employment contracts. Divergence is primarily witnessed in the degree of involvement of trade unions and governments in employee relations. The differences in patterns observed between the countries can be attributed to the unique institutional factors of each country.

Do celebrities have it all? Context collapse and the networked publics

Asha Kaul and Vidhi Chaudhri

Journal of Human Values

With the advent of social media and increase in networked publics, context collapse has emerged as a critical topic in the discussion of imagined audiences and blurring of the private and the public. The meshing of social contexts portends problematic issues as messages inadvertently reach unimagined audiences causing shame and leading to loss of ‘face’. In this article, we specifically study the impact of context collapse on some celebrities ‘who had it all’ yet, lost ‘it some’ to the world of networked public. The article examines celebrities sharing identity information across multiple contexts and explores situations of lost fame when ‘face’ is threatened, usage falters and breaks some of the well-established norms of interactivity. It concludes that lack of prudence in separating social contexts, loss of ‘face’ and social approval can dampen online celebrity presence. It proposes the use of ‘polysemy’ to simultaneously appeal to audiences from different contexts.
