One foot in the city, one in the village: India’s urban poor and their rural bonds
When many of India’s poor move from their rural homes to the country’s packed cities, they remain registered in their village. Here Ankush Agrawal (Indian Institute of Technology Delhi) and Vikas Kumar (Azim Premji University, Bengaluru) explain the reasons why India’s urban poor keep a foot in villages and its policy consequences
Improved Kerogen Models for Determining Thermal Maturity and Hydrocarbon Potential of Shale
Kerogen is the insoluble component of organic-rich shales that controls the type and amount of
hydrocarbons generated in conventional and unconventional reservoirs. Significant progress has
recently been made in developing structural models of kerogen. However, there is still a large gap in understanding the evolution of the molecular components of kerogen with thermal maturation and their hydrocarbon (HC) generative potential. Here, we determine the variations in different molecular fragments of kerogen from a Marcellus Shale maturity series (with VRo ranging from 0.8 to 3) using quantitative 13C MultiCP/MAS NMR and MultiCP NMR/DD (dipolar dephasing). These molecular variations provide insight into the (1) evolution of the molecular structure of kerogen with increasing thermal maturity and, (2) the primary molecular contributors to HC generation. Our results also indicate that old model equations based on structural parameters of kerogen underestimate the thermal maturity and overestimate the HC generation potential of Marcellus Shale samples. This could primarily be due to the fact that the kerogen samples used to reconstruct old models were mostly derived from immature shales (VRo \u3c1) acquired from different basins with varying depositional environments. We utilized the kerogen molecular parameters determined from the Marcellus maturity series samples to develop improved models for determining thermal maturity and HC potential of Marcellus Shale. The models generated in this study could also potentially be applied to other shales of similar maturity range and paleo-depositional environments
A New In-Store Digital Landscape: Effect on Engagement, Innovativeness, and Unplanned Grocery Shopping Outcomes
Digital technologies are having a profound effect on the path to purchase in a grocery retail environment. Secondary research data on shopping habits is used to analyze the relationship of consumer digital technology use, a consumer’s innovativeness, and consumer engagement with unplanned grocery shopping behavior within a grocery store environment. Findings indicate that all of three variables have a direct, significant effect on unplanned grocery shopping outcomes and that innovativeness has a direct effect on engagement. Future study will consider the impact of key market segments, shopping situations and digital technology types
Enabling Knowledge Sharing Through Intrinsic Motivation And Perceived IT Support
Knowledge is currently viewed as a key organizational resource to gain and sustain competitive advantage. Having the right knowledge at the right time to take effective action has become ever more critical for organizations. A key aspect of achieving this is by promoting conditions that enable organizational members to share their knowledge in the most effective manner. This research investigates the impact of knowledge workers’ intrinsic motivation and their perceived usefulness of information technology support on knowledge sharing. The proposed model is tested using data from a sample of 252 knowledge workers in manufacturing and related industries. Results support proposed hypotheses suggesting that knowledge workers intrinsic motivation and perception of usefulness of information technology support positively affects knowledge sharing. Intrinsic motivation also affects knowledge sharing indirectly by enhancing knowledge workers’ perception of information technology they use to share knowledge. This research underscores the importance of individual characteristics such as motivation and employee perception in sharing knowledge
Linking Information Sharing And Supplier Network Responsiveness With Delivery Dependability Of A Firm
The twenty first century organization is required to provide accurate on time deliveries in addition to providing high quality products at low costs. This can be achieved if various processes within and between the organizations are streamlined and well defined. Several studies have indicated the significance of various manufacturing (or internal) practices that are instrumental in creating time-based competitive capability. Collaborative relations and information sharing practices with suppliers have long been believed to positively impact the responsiveness and delivery performance of organizations and supply chains. Responsive suppliers can play a key role in affecting a firm’s own delivery performance. This research investigates and tests the relationships between information sharing practices of a firm, supplier network responsiveness, and delivery dependability of a firm. The large scale web-based survey yielded 294 responses from industry professionals in the manufacturing and supply chain area. The proposed relationships were tested using structural equation modeling. The research findings point out that higher level of information sharing practices can lead to improved supplier network responsiveness, and higher levels of supplier network responsiveness can have a direct positive impact on delivery dependability of a firm. The implications of our findings are discussed and directions for future research are provided
The New In-Store Consumer: Digital, Engagement, Innovativeness Impact on Unplanned Grocery Shopping and Spending Behavior
Digital technologies are having a profound effect on the grocery retail environment worldwide. Marketers have been intrigued by potential for digital technologies to influence consumers at the point of purchase, yet little is known about how digital technologies impact consumer purchasing decisions. An exploratory PLS-SEM model is used to analyze U. S. panel data and the effect of in-store digital use, consumer innovativeness and engagement on unplanned grocery shopping behavior and spending. This study finds that consumer engagement, rather than in-store digital use, is found to be the key variable when it comes to predicting unplanned shopping and spending. Findings identify an ancillary role for in-store digital use as it directly affects engagement and indirectly affects unplanned shopping and spending. Finally, this study finds that gender moderates the relationship of innovativeness and digital use, digital use and engagement, and digital use and total spending. As a result, the effects of consumer engagement and in-store digital use on unplanned purchase behavior have been clarified
A bi-criteria evolutionary algorithm for a constrained multi-depot vehicle routing problem
Most research about the vehicle routing problem (VRP) does not collectively address many of the constraints that real-world transportation companies have regarding route assignments. Consequently, our primary objective is to explore solutions for real-world VRPs with a heterogeneous fleet of vehicles, multi-depot subcontractors (drivers), and pickup/delivery time window and location constraints. We use a nested bi-criteria genetic algorithm (GA) to minimize the total time to complete all jobs with the fewest number of route drivers. Our model will explore the issue of weighting the objectives (total time vs. number of drivers) and provide Pareto front solutions that can be used to make decisions on a case-by-case basis. Three different real-world data sets were used to compare the results of our GA vs. transportation field experts’ job assignments. For the three data sets, all 21 Pareto efficient solutions yielded improved overall job completion times. In 57 % (12/21) of the cases, the Pareto efficient solutions also utilized fewer drivers than the field experts’ job allocation strategies

Simulation Model and Analysis of a Data Warehouse
Data warehouses are large complex systems with many interacting nonlinear components. It is an amalgamation of many different systems and integration of such diverse elements is its primary concern. It is often difficult for a data warehouse manager to predict the performance of the system especially when demand pattern for the required data keeps changing. We have developed a simulation model using ARENA simulation package that will simulate the behavior and performance of a data warehouse system environment based on its overall design. Given such a model, a data warehouse manager can walk through various what-if scenarios and can pinpoint the areas of weaknesses in the system. This visibility could result in improved operational performance in a data warehouse
Notes on Nagaland’s area
Empirical research in economics and, to a lesser extent, in other social sciences is largely
dependent upon government statistics. It is generally assumed that governments are
committed to collecting and disseminating correct statistics. As a result, the mutually
constitutive relationship between politics, economy, and statistics, and the possibility of
systematic manipulation of statistics driven by the structural features of this relationship,
has received insuf�icient attention within economics. This paper examines the implications
of the absence of shared preferences over the quality of statistics within a government. It
explores the multiplicity of con�licting maps of the State of Nagaland issued by different
tiers and wings of the government to underscore the lack of attention paid to a statistic
as crucial as area. The paper situates the cartographic-statistical confusion in its political
and economic contexts, and suggeststhat political-geographic arguments are being used to
advance political-economic interests along contested borders. It argues that the confusion
is not amenable to a technical resolution as it islinked to the dispute over Nagaland’s place
within the Union of India and the border disputes between Nagaland and its neighbouring
states
The New Grocery Retail Journey: Stimuli and Mobile Influences on a Consumer’s Unplanned Shopping and Spending Behavior
In the new digital age, knowing what new variables may be affecting unplanned shopping and spending in a grocery store environment has had little conclusive study academically, albeit is very important to academic theory, grocery store chain management and manufacturers. Many grocery shoppers are now utilizing mobile phones and other digital stimuli (via an app or website, pricing information, coupons, QR codes, or other information) in addition to traditional stimuli for product or promotional information during their in-store purchase phase. In past research, new in-store digital stimuli or mobile phone technology was shown to increase unplanned shopping and/or spending (Cake et al., 2018 a, b; Grewal et al., 2018; Hui et al., 2013; Sciandra & Inman, 2013). However, Bellini and Aiolfi (2018) found that mobile use in store actually decreased unplanned purchases and suggested that using a mobile phone be helping a customer to plan and monitor an in-store shopping experience, keeping track of purchases and a set shopping budget. This survey was emailed through a major grocery store chain’s store panel list; respondents who had shopped in the last 7 days were analyzed. The influence of traditional stimuli (flyers, coupons, displays), digital stimuli (web site use, retail apps, texts etc.), use of a shopping list, and a mobile phone’s effect on in-store unplanned shopping and spending were studied, along with new products, familiar brands, package appeal, and product information influence. Multiple regression was used to determine the effect of these independent variables on unplanned shopping and spending. Preliminary results show that several variables including new products, displays, traditional in-store promotion offers affect unplanned shopping positively, while use of a list have a predicted negative affect on unplanned purchases. Mobile phone use, both for shopping and non-shopping use, as well as digital/online promotional offers do not affect unplanned shopping significantly. However, mobile phone use in store and digital/online promotional offers do positively affect spending. This research leads to a better understanding of what causes unplanned purchases and additional spending and lends itself to new academic theory, as well as to retailers and manufacturers, who could use this information to develop marketing strategies which may increase their revenue, engagement of customers, and customer satisfaction. In the near future, consumer engagement and innovativeness, hedonistic and utilitarian traits, and price and health consciousness’ effect on unplanned purchases and spending will be completed
