Ergonomic basket design to reduce cumulative trauma disorders in tea leaf plucking operation

Work related musculoskeletal disorders are seen as an indicating parameter of occupational stress among the women workers engaged in tea leaf plucking operation. The hand plucking (no mechanized plucking is practiced in Assam) being a highly repetitive task requires forceful exertions to reach to the distant periphery of the tea bushes and mechanical compression (pressing against hard surfaces). Specifically it aggravates with awkward positions adopted. The current research addresses to minimize the risk factors associated with CTDs and to ascertain the role of ergonomic design development in improving the situation. Women workforce engaged in tea industry in Assam suffer from back, shoulder, arm and finger pains. Workers perform the activity for 440 minutes in the entire shift with one hour lunch break in between in the garden itself. An ergonomic investigation aiming at studying the strain index of plucking operation in tea industry was conducted. While performing the operation workers were found to assume unnatural posture which is static as well as highly dynamic with a load (tea leaf collecting basket up to weight of 30 kg when filled with plucked leaves) at back. With gradual increment of load and pain though the load is released intermittently the strain level found to remain at a high level. The total QEC scores found for plucking activity was 110 out of 138. To improve the situation and to reduce the work related upper limb disorder (WRULD) an ergonomically designed basket was conceived and trial results showed improvements. The newly designed plucking basket fits the back curvature of the workers well, which keeps the basket in place unlike the existing round basket. The new basket is light in weight having more leaf capacity. Significant reduction in energy expenditure and MSDs suffered was observed while using improved basket over existing basket.     

Emotion and interior space design: an ergonomic perspective

Interaction between the users and their environment is spontaneous and unavoidable. This interaction can be positive or negative. A good interior space is about considering all the physical, environmental and cognitive elements and harmonizing them to make it a space that feels right, functionally and emotionally. The important element that has to be considered the most in an interior space is the "user". Balancing all these elements is a challenging job and results in a perfect interior space design. This paper intends to bring to light the necessity of designing an optimum interior space, which is a balance of the user's choice and the mandatory standards that ought to be followed for user safety and convenience. There has to be an intervening domain of ergonomics which will guide to bring out a balance between the personal choice of the user and the usual standards followed. It should also provide a step-by-step information, guidance and direction to act to the specifications and standards systematically to adapt an integrated approach of handling all the elements holistically which will indeed result in a good interior space.     

Partial cooperation in strategic multi-sided decision situations

We consider a normal-form game in which there is a single exogenously given coalition of cooperating players that can write a binding agreement on pre-selected actions. The actions representing other dimensions of the strategy space remain under the sovereign, individual control of the players. We consider a standard extension of the Nash equilibrium concept denoted as a partial cooperative equilibrium as well as an equilibrium concept in which the coalition of cooperators has a leadership position. Existence results are stated and we identify conditions under which the various equilibrium concepts are equivalent. We apply this framework to existing models of multi-market oligopolies and international pollution abatement. In a multi-market oligopoly, typically, a merger paradox emerges in the partial cooperative equilibrium. The paradox vanishes if the cartel attains a leadership position. For international pollution abatement treaties, cooperation by a sufficiently large group of countries results in a Pareto improvement over the standard tragedy of the commons outcome described by the Nash equilibrium.     

When outsourcing fragments: customer creativity and technological transmutations

One of the most fundamental decisions made in firms is about what functions or activities the firm should perform within its own hierarchy, and which of these it should rely on the market to perform. Outsourcing is ‘an agreement in which one company contracts out a part of their existing internal activity to another company’. However, this article contends that outsourcing has changed, and is changing in ways that make the application of neat, legal and technically correct definitions hard to use, and even harder to apply in strategy. Under the new outsourcing paradigm, technology is not a passive ‘substance’, rather it is an active ‘force’. We aim to look at the ways in which technologies are re-shaped and transmuted by consumers. Through this analysis, we add the consumer activity to the conventional definition of outsourcing. We focus on one of the most highly anticipated and influential new products of 2007 – the Apple iPhone.

Import competition, employment and wages in U.S. manufacturing

This paper uses cointegration analysis to examine if employment and wages in the U.S. manufacturing sector exhibit any long run relationship with import competition. While overall the cointegration analysis supports the results reported in Revenga’s (1992) panel study it indicates that in the long run a positive correlation between import price and employment and/or a negative correlation between import price and wage are sector sensitive. There is also a considerable variation in the magnitude of employment and wage elasticities.     

An empirical analysis of innovation strategies of biotechnology firms in the U.S.

The paper explores the strategies of biotechnology firms in the U.S. through a mail questionnaire study. Based on the responses of 89 companies we have developed strategy archetypes of these firms in R&D, marketing, and technology acquisition. In R&D, we found the firms to follow either incremental or radical strategy. In marketing, the firms use either a defender or an innovator strategy. In technology acquisition, firms differ in terms of their emphasis on licensing or developing new technology. The interrelationship among the strategy groups is weak. The R&D and technology acquisition strategies are related in the sense that aggressive technology strategy dictates radical R&D behavior with emphasis on development of new technology. We have found that firms following aggressive technology strategy tend to follow conservative marketing strategy. This is consistent with an earlier study by of German firms where it was found that firms tend to balance their technical and marketing risks. The paper also provides additional information about the factors considered to be important in product decisions for various strategies.     

Transfer of learning: concept and process

This article will present findings from a doctoral study exploring the impact of 'SVQ Care: Promoting Independence (level III)' within children's homes. The study focuses on the extent to which SVQs enhance practice and their function within a 'learning society'. A total of 30 staff were selected from seven children's homes in two different local authority social work departments in Scotland. Each member of staff was interviewed on four separate occasions over a period of 9 months. Interviews were structured using a combination of repertory grids and questions. Particular focus was given to the assessment process, the extent to which SVQs enhance practice and the learning experiences of staff. The findings suggest that there are considerable deficiencies both in terms of the SVQ format and the way in which children's homes are structured for the assessment of competence. Rather than address the history of failure within residential care, it appears that SVQs have enabled the status quo to be maintained whilst creating an 'illusion' of change within a learning society.     

The impact of globalization and financial development on India’s income inequality

This paper empirically examines the combined effects of globalization and financial development on income inequality in a unified framework for an emerging economy. Using annual data for the Indian economy over the period 1980–2014, we show that the perceived benefits of globalization and financial development have not trickled down; rather, has aggravated income inequality. Our results also indicate that while inflation aggravates income inequality, education seems to alleviate the differential effect. Proactive measures in providing access to financial services, creating equitable employment opportunities, and improving the quality of education are required to offset the negative impacts of globalization and financial development on income disparity.     

Prevalence of snoring in college students

Snoring in college students may be the earliest presentation of adult sleep-disordered breathing, yet the literature contains few studies that demonstrate its effects on learning or whether early diagnosis leads to interruption of disease progression or prevention of comorbidities. OBJECTIVE AND PARTICIPANTS: The authors conducted this study in January-April 2004 to assess the prevalence of snoring in college students (N = 2,200). METHODS: They developed a questionnaire on sleep behaviors and distributed it to 18- to 25-year-old undergraduates at a California university. RESULTS: Almost one-third (30%) of participants reported snoring. The prevalence of snoring was higher among men than women (42% and 25%, respectively). The prevalence of self-reported snoring was highest in Asian students (37%). CONCLUSIONS: Snoring is highly prevalent in college students; prevalence is higher in men than women, correlates with body mass index, and varies by ethnicity.
