This paper introduces ARCI′ (Adjusted Rural Connectivity Index), a novel graph-theoretic metric designed to evaluate and optimize sparse networks by balancing construction cost and population coverage. Traditional minimum spanning tree (MST) approaches focus solely on minimizing cost, often neglecting social factors such as population distribution. ARCI′ incorporates a penalty factor to weigh network cost against population served, allowing flexible prioritization. We analyze ARCI′ mathematically, study its sensitivity to the penalty parameter, and demonstrate its utility through computational experiments on synthetic network data. Our results highlight ARCI′ as a promising metric for multi-objective network design in rural infrastructure, sensor placement, and related fields.

Topological indices play a significant role in chemical graph theory by providing quantitative measures of molecular structures. Most existing indices are focused on organic compounds, particularly hydrocarbons, with limited applicability to inorganic acids. In this work, we propose a novel graph-theoretical index, the Tareq Index (TI), specifically designed to reflect bonding patterns in inorganic acid molecules. This index incorporates bond multiplicity and molecular connectivity, capturing characteristics often overlooked by traditional indices like the Zagreb or Randić indices. A dataset of over 20 inorganic acids was analyzed, with the TI compared against pKa values and other topological descriptors. Preliminary trends indicate a potential correlation between TI values and acid strength. This contribution offers a new avenue for the structural interpretation of inorganic compounds and lays the foundation for further expansion into quantitative structure–activity/property relationships (QSAR/QSPR) involving inorganic systems.

This chapter explores the concept of e-health as it relates to healthcare delivery, healthcare quality and education. Although the concept of e-health is emerging and lacks clear definition, a body of literature in healthcare policy and organization has focused on many of themes and ideas that are relevant to the study of e-health. This chapter introduces several frameworks and concepts that are essential for an inquiry into the relationships between e-health and quality-related outcomes in healthcare and educational settings. This chapter addresses these relationships by discussing and defining the concept of e-health, discussing central linkages between e-health and quality-related healthcare outcomes, and highlighting key themes between health education, technology and quality.Request access from your librarian to read this chapter's full text.

Human resources are central to healthcare services, yet leveraging these resources to meet strategic operations and operational outcomes can present challenges to leaders and human resources professionals because of the complex and dynamic nature of healthcare delivery. Although the traditional roles of human resources management are necessary in supporting an organization in meeting its goals, economic, strategic, and cultural considerations are becoming increasingly important to human resources management and workforce planning in healthcare settings. This chapter presents several features of these different lenses to assist human resources managers in developing a holistic view of human resources planning in health care.

The purple velvet plant ( Gynura aurantiaca ) has commercial potential as a potted plant due to its attractive purple foliage, if the malodorous flowers can be avoided. Plants were treated with seven concentrations of ethephon, three photoperiodic durations, three light intensities, and combinations of photoperiod and light intensity to inhibit flowering. Although foliar application of ethephon at 1200 to 4800 ppm (μL·L -1 ) completely inhibited flowering of purple velvet plants, plants were stunted and cutting harvest was impossible. Flowering was promoted at lower application rates of 150 to 300 ppm (μL·L -1 ). An 8-hour photoperiod increased plant quality and plants had the largest vegetative shoot number and the brightest purple color, compared to 12 or 16-hour photoperiods. All of the shoots were reproductive under the 16-hour photoperiod. Increasing the shade level from 0 to 60% (790 μmol·m -2 ·s -1 to 230 μmol·m -2 ·s -1 ) increased the number of vegetative shoots at 74 and 108 days after treatment commenced but reduced the total number of shoots by 28% at day 108. Plants grown under60% shade and short days had 94% vegetative shoots 102 days after placement in treatment. Growing plants under 8-hour photoperiod and 60% shade from fall to spring is recommended to maintain vegetative stock plants and produce high quality marketable plants. Chemical names used: (2-chloroethyl) phosphonic acid (ethephon).
