What Makes a Data-Story Work?
A Framework for Effective Visual Data Narratives

Amit Kapoor and Kavitha Ranganathan

Stories have been recognized for their power of communication & persuasion for centuries and we need to operate at that intersection of data, visual and stories to fully harness the power of data. Online journalism has already started to show the path but we need to develop the science of data-story to get them widely adopted in business. We used a case study based approach to map the four different layers in a data-story: See - Show - Tell - Engage. We developed a framework of key dimensions within each of these layers and then rigorously analyzed 25 carefully selected case-studies to see which elements were being employed in the data-story. We focused not only on the dimensions of data abstraction and visual representation, framing and transition but also on the dimensions of story structure, point-of-view, relatability and engagement through emotions, takeaways and interaction. Our framework indicates generic strategies that can be used for effective data-stories using exploratory and explanatory visualization in personal and presentation context.

Sacrifice Ratio and Cost of Inflation for the Indian Economy

Ravindra H. Dholakia

Traditional concept of the Sacrifice Ratio measures the loss of potential output sustained by the society in the medium term to achieve reduction in the long-run inflation by one percentage point. This concept is critically examined and generalized to include episodes increasing the long-run inflation rate to gain higher growth of output and employment and hence reduction in the poverty proportion in the medium term. Since the concept needs measurement through a shifting short-run equilibrium of dynamic aggregate demand and supply in terms of inflation rate and output attributable to monetary policy interventions, its estimation is challenging. There are two alternative approaches to estimate the ratio, the direct one and regression based. Both have their relative merits and demerits. The regression based approach provides one unique average estimate of the Sacrifice Ratio for all episodes but allows holding other factors constant. The direct approach provides separate estimates by episodes but fails to hold other factors constant. The Sacrifice Ratio turns out to be in a narrow range of 1.8 to 2.1 for deliberate deflation and 2.8 for inflation in India. On the other hand, benefits of one percentage point reduction in trend rate of inflation are at best 0.5 percentage points increase in long-term growth of output that occurs after 4-5 years. This has implications on policy to disinflate.

Midwifery education within the integrated nursing and midwifery programmes in India

Bharati Sharma, Ingegerd Hildingsson, Eva Johanson, K. V. Ramani, and Kyllike Christensson

Staff nurses (nurse-midwives) in India are expected to provide normal birth services in health facilities under the maternal health strategy of the National Rural Health Mission. Under the integrated nursing and midwifery programme in India, every nurse graduate has some midwifery education which may not be adequate for this role.

To assess confidence of students in four domains of midwifery skills of the International Confederation of Midwives,just before graduation, namely antepartum, intrapartum, postpartum and newborn care. The study further compares confidence levels of students from the diploma and bachelor programmes.

Self-reported confidence data was obtained from 633 final year students from diploma and bachelor's programmes in one district, from 25 randomly selected schools and colleges of nursing. An explorative factor analyses using principal component analysis (PCA) for the four competency domains was done.Relationship between type of program and self-assessed confidence unadjusted and adjusted logistic regression models were performed.

Sixty five per cent students did not meet the national registration requirements ofnumber of assisted and independent births. Except for managing high risk pregnancies the students were confident in other antepartum skills. More than 40% of all students expressed low confidence in most of the intrapartum skills. Students expressed low confidence for first level care for postpartum complications and some basic skills such as assessing involution, and healing of lacerations. Except for newborn complications, the students expressed confidence in most basic newborn care skills. Students in the diploma program were significantly more confident in all skill areas with 2-7 times higher odds for self-assessed high confidence.

Students graduating from the diploma and bachelor's programme do not feel confident in fulfilling their role of normal births as expected under the national strategy on maternal health. They need more hands on clinical experience especially for intra partum care, and for recognition and initiating life saving measures for complications.

Prevention of postpartum infections using 'Appreciative Inquiry'

Bharati Sharma, K. V. Ramani, Dileep Mavalankar, Lovney Kanguru, and Julia Hussein

The objective of the present study was to explore how infection rates in study hospitals were affected by an intervention in six intervention hospitals in Gujarat, India. Infection control practices, human resource management, infrastructure, supplies and associated health system factors were investigated.
Methods

This study was conducted within a controlled, interrupted time series study where a reduction in infection rates was observed. The intervention was a process called Appreciative Inquiry (AI), an organisational change agent which focuses on positive aspects (what is done well) where hospital personnel were brought together to share experiences and agree on action plans for improving infection control. Three to six months after the intervention, 31 in-depth interviews were conducted. Monthly observation check lists were also used to investigate the perceived influence of AI and underlying health system factors.

AI was perceived as having a positive influence on team relationships; improving communication across the power hierarchy of hospitals; fostering trust and cooperation with inclusion of the marginalized and non-technical staff in the team; and developing better understanding of one's own role and those of the others. The intervention did not lead to changes in human resource policies, financial and information systems or leadership and governance. Pre-existing factors such as power and autonomy of leaders, the leader's motivation for change, leadership styles and a background of organizational reform such as accreditation influenced the AI process.

Infection control is a complex phenomenon both being influenced by and influencing health systems. Organizational factors such as distribution of power across staff hierarchy, inclusive decision making and problem solving seem to influence team performance. Social factors such as status of women, and caste and social hierarchies influence team relationships in health care settings. Appreciative inquiry as an organizational change method has the potential to change infection control behaviours of health care teams by not only targeting health systems but the underlying organizational and social factors thereby strengthening teams and staff morale.It is a means for developing a shared ideology and values for improved service delivery, thereby setting-up an organisational 'work culture'. Enabling environments such as accreditation appear to put organizations into a receptive, high alert, active mode.

High Frequency Manipulation at Futures Expiry: The Case of Cash Settled Indian Single Stock Futures

Sobhesh Kumar Agarwalla, Joshy Jacob, and Jayanth R. Varma

Futures markets are known to be vulnerable to manipulation, and despite the presence of a variety of mechanisms to prevent such manipulation, instances of market manipulation have been found in some of the largest and most liquid futures markets worldwide. In 2013, the Securities and Exchange Board of India identified a case of alleged manipulation (in September 2012) of the settlement price of cash settled single stock futures based on high frequency circular trading. As is well known, it is easy for any well-endowed manipulator to manipulate the price; the real challenge for the manipulator is to make the manipulation profitable. The use of high frequency circular trading of the form alleged in the SEBI order makes many forms of manipulation profitable, and makes futures market manipulation a much bigger problem than previously thought.

As argued by Pirrong (2004), it is more practical to detect and punish manipulation than to try and prevent it. We develop an econometric technique that uses high frequency data and which can be integrated with the automated surveillance system to identify suspected cases of high frequency manipulation at futures expiry. We then use these techniques to identify a few suspected cases of manipulation. Needless to say, human judgement needs to be applied to decide which, if any, of these cases need to be taken up for investigation (and, after that, possible prosecution). This judgement is beyond the scope of our paper, and we refrain from making any judgement on whether any of the identified cases constitutes actual market manipulation.

Predicting Helpfulness of Online Customer Reviews

Srikumar Krishnamoorthy

Helpfulness of online reviews plays an important role in customer purchase decision making process. However, the review helpfulness prediction problem is considered to be quite challenging and hard. This paper aims to explore this problem and build a helpfulness pre-
diction model. Our model utilizes a rich set of features based on textual content of reviews, meta-data of reviews and characteristics of reviewers. The proposed predictive model is validated using six real-life review datasets and the experimental results are found to be
quite promising. Our experimental analysis of the impact of product type such as search and experience goods on review helpfulness also reveals interesting insights.

The role of complementarity and partner brand price level in new product introduction strategy using bundle offers:
A study on the quality perception of bundle components.

Kapil Khandeparkar

New products are often bundled with strong brands as an introduction strategy. This study helps to understand the scenarios which will be most beneficial to both the products in the bundle. The enhancement effect and categorisation theory is used to explain that the new products quality perception is higher when it is bundled with a strong brand of a higher price and this effect is moderated by the complementarity of the bundled components. Also, the quality perception of the strong brand is rated higher when it is bundled with a new product of assured quality.

Issues in PPPs in Ports in India

G. Raghuram and Shukla Niraja

PPP mode of investment in Indian ports has made a significant headway and is preferred for investments today. The 12 major ports and about 200 minor ports along the 7,500 km coastline of the country have together traded about 935 mt of cargo in 2012-13. The traffic is growing each year. The share of non major ports is rising and has reached 42% in year 2012-13. The PPP mode was more popular at non major ports controlled by the State Government, than major ports controlled by Central Government. During the XI Plan, the overall investment in the port sector was significantly lower than planned. It has had an impact on the efficacy of PPP investment in this sector. This paper analyses the issues behind this, to evolve the way forward.

The issues which the port authorities or private parties have faced so far should be of interest to stakeholders wanting to leverage the PPP mode of investment. While there are arguments for and against this mode, the overall outlook for PPPs has been positive in terms of bringing about competition, fairness in operations, efficiency and quality of service.

Bridging the Creativity – Innovation Divide: An Investigation of R&D Professionals' Experiences from India

Vishal Gupta

The present study presents a qualitative study of the process through which creative ideas are converted into new products. Based on a grounded-theoretic investigation of 52 interviews conducted with scientists working in 5 Indian R&D laboratories, the study explores the socio-psychological factors that affect the creativity-innovation conversion process. Our results demonstrate that the critical innovative work behavior that impacts the conversion process is mobilizing support behavior that is defined as promoting ideas to others and garnering support and resources for their implementation. While ideas can occur at the individual (or group) level, unless the individual (or group) mobilizes support for the ideas, the chances for their successful implementation are minimal. The study next explores the individual-, team- and organization-level factors that influence the creativity-innovation process either directly or indirectly (by promoting mobilizing support behavior). The study reveals that for innovation to occur, creativity needs to be backed up by other factors like leadership, team work, organizational factors, fairness and acquisition of resources. It is this interlinking of factors that leads to innovative output. We present a conceptual framework that describes in what ways these factors are linked to each other. Implications for theory and practice are discussed.
