Set A - Question 3

Question Details

A research scholar has completed a study on the adoption of renewable energy technologies in rural households and is now in the dissemination phase. The scholar intends to submit a technical report to the funding agency, publish in a peer-reviewed journal, share preliminary findings at an international conference, and face the final viva-voce examination.

• A. What type of conference presentation would be most appropriate when the scholar wishes to display the findings on a single display board and interact informally with delegates on a one-to-one basis? Justify your choice. (5 Marks)

• B. Design an appropriate data visualization strategy for presenting adoption trends and cost-benefit outcomes to the target audience. Explain how audience analysis influences the choice of visualization. (5 Marks)

• C. A researcher has published 24 papers with varying citation counts as shown in the table provided. Calculate the $h$-index and $g$-index of the researcher. Plot a suitable graph to visually represent the indices. (5 Marks)

Model Answer

A. What type of conference presentation would be most appropriate when the scholar wishes to display the findings on a single display board and interact informally with delegates on a one-to-one basis? Justify your choice. (5 Marks)

1. Selected Presentation Type (1 Mark)

• Poster Presentation (Interactive Poster Session).

2. Justification (4 Marks)

1. Single Board Modality: Displays the complete research story (context, methodology, field photos, adoption charts, conclusions) compactly on a single standard A0/A1 board.
2. One-to-One Interaction: Facilitates conversational, two-way dialogue with individual delegates, unlike the rigid, one-directional format of oral podium talks.
3. Flexible Pacing: Allows the presenter to adjust depth instantly-providing a quick summary for general visitors or a deep technical explanation for energy specialists.
4. Targeted Networking: Attracts delegates specifically interested in rural renewable technologies, creating direct opportunities for collaboration and funding.

B. Design an appropriate data visualization strategy for presenting adoption trends and cost-benefit outcomes to the target audience. Explain how audience analysis influences the choice of visualization. (5 Marks)

1. Visualization Strategy (3 Marks)

• Adoption Trends:
  • Multi-Line Time-Series Chart: Plots years ($X$-axis) against adoption rates ($Y$-axis) for solar PV, biogas, and clean cooking technologies.
  • 100% Stacked Bar Chart: Compares adoption proportions across socioeconomic income brackets and village blocks.
• Cost-Benefit Outcomes:
  • Break-Even / Payback Curve: Plots cumulative operational energy savings against initial CapEx to pinpoint the exact break-even year.
  • Clustered Waterfall Chart: Compares traditional fuel costs against subsidized renewable lifecycle expenses.

2. Influence of Audience Analysis (2 Marks)

• Funding Agencies: Need executive KPI dashboards, Net Present Value (NPV), and clear return-on-investment (ROI) charts.
• Conference Delegates: Require statistical rigor, including scatter plots with regression trendlines, sample sizes ($n$), and confidence intervals ($p < 0.05$).
• Rural Community: Need simple pictorial infographics, vernacular labels, and monthly savings in local currency (Rs. saved/month).

C. Calculate the $h$-index and $g$-index of the researcher and plot a suitable graph to visually represent the indices. (5 Marks)

1. Ranked Citation Table (1.5 Marks)

Sort the 24 papers in descending order of citations ($c_i$), compute cumulative citations ($\sum c$), and compare against $i$ and $i^2$:

Rank ($i$)	Citations ($c_i$)	Cum. Citations ($\sum c$)	$c_i \ge i$ ($h$-test)	$i^2$	$\sum c \ge i^2$ ($g$-test)
1-17	150 down to 20	150 to 995	True	1 to 289	True
18	18	1013	True ($18 \ge 18$)	324	True
19	15	1028	False ($15 < 19$)	361	True
20	12	1040	False	400	True
21-23	10, 8, 5	1050 to 1063	False	441 to 529	True
24	3	1066	False	576	True ($1066 \ge 576$)

2. Index Calculations (2 Marks)

• $h$-index (1 Mark):
  The largest rank $h$ where $c_h \ge h$.
  At rank 18: $18 \ge 18$ (True); at rank 19: $15 < 19$ (False).
  $\mathbf{h\text{-index} = 18}$
• $g$-index (1 Mark):
  The largest rank $g$ where $\sum_{k=1}^g c_k \ge g^2$.
  At rank 24: Cumulative citations = $1066 \ge 24^2 = 576$.
  Since the researcher published 24 papers in total, the index is bounded by total publications:
  $\mathbf{g\text{-index} = 24}$
  (Theoretical citation ceiling: $\lfloor \sqrt{1066} \rfloor = 32$.)

3. Visual Representation (1.5 Marks)

Given Data

• Citations in 2023 = 820 | Papers in 2023 = 210
• Citations in 2022 = 940 | Papers in 2022 = 190
• Citations in 2021 = 700 | Papers in 2021 = 200

1. Journal Impact Factor (JIF) for 2023 (2.5 Marks)

Measures citations in 2023 to articles published in the preceding two calendar years (2021 and 2022):

$\text{JIF}_{2023} = \frac{\text{Citations in 2023 to (2021 + 2022)}}{\text{Papers published in (2021 + 2022)}} = \frac{820}{200 + 190} = \frac{820}{390} \approx \mathbf{2.10}$

---

2. CiteScore Calculation (2.5 Marks)

• Standard Scopus 4-Year Window (2020-2023):
  $\text{CiteScore} = \frac{\text{Total citations in 4 years (2020-2023)}}{\text{Total papers in 4 years (2020-2023)}} = \frac{600 + 700 + 940 + 820}{180 + 200 + 190 + 210} = \frac{3060}{780} \approx \mathbf{3.92}$
• (Alternative 3-year legacy window: $\frac{820}{180 + 200 + 190} = \frac{820}{570} \approx \mathbf{1.44}$).
