AgroGuardian: An All-Terrain Vehicle Crash Detection and Notification System

Highlights Off-road ATV incidents can be problematic due to long EMS alert times. An ATV crash-detection-and-report system is expected to reduce EMS response time. The developed system can accurately detect ATV rollovers. The alert time of our system is 10 times faster than the national U.S. average. Any rider using our system is 3 times more likely to survive an off-road crash. Abstract. All-Terrain Vehicle (ATV) incidents are a common cause of injury and death in the agricultural industry in the United States. Many ATV off-road crashes on farms and ranches may result in trauma requiring immediate care, but the injured rider is unable to seek help due to their injuries. Moreover, many of these crashes occur in isolated areas that may be difficult to access and have unreliable cellular phone service, making contact with emergency medical services (EMS) challenging. This study aimed at developing and testing a low-cost ATV crash detection device (AgroGuardian) that immediately alerts EMS and emergency contacts, even when the rider is unable to take action and/or there is no cellular phone service available. AgroGuardian includes an embedded data logging system, a smartphone application, and a remote database. The embedded system includes an Inertial Measurement Unit (IMU) for attitude estimation, a Global Positioning System (GPS) for location estimation, and a Rock7 modem for off-board communication. A smartphone application was developed for the users to input information about their vehicle (e.g., make and model) and emergency contacts. Also, it allows them to interact with their ATV data. An emergency signal along with the ATV’s coordinates is transmitted through the Rock7 modem and received in the remote database when a rollover is detected by the system. This emergency signal is then processed and sent to EMS and emergency contacts. Our results indicated that the device: (1) is unlikely to miss an ATV rollover; (2) has a fast EMS notification time (40.7 s); and (3) the ATV localization system presented an average error of 2.34 m. Keywords: ATV, EMS alert time, Farm, Off-road incidents, Quadbike, Rollover.

Consumer Trust as a Mediator of the Link Between Promotional Mix and Customer’s Decision to Use Cellular Phone Service

Customer’s (use) purchasing decision making have the crucial point of several marketing decision-makers in all type of businesses. Studies have suggested that ambiguity still exist in terms of variables capable of enhancing the indirect link between the promotional mix (PM) and customer’s purchasing (use) decision, specifically in the cellular communication sectors of most of the developing countries. This study is an attempt to explore the link between promotional mix (PM), consumer trust, and customer use decisions in the context of Yemen cellular communications sector. The hierarchy of effects theory is used as underlying theory, and quantitative cross-sectional survey method with questionnaire were used in collecting data.

A Review of Role of Mobile Based Advisory System for Transfer of Technologies for Sustainable Agricultural Development

Mobile phones have established itself in the rural areas and are becoming quite popular both with farmer and farm women. These powerful electronic machines that were a farmer’s dream earlier have become a reality as the farmer’s can immediately make use of them to address their field problems and other farm difficulties. The Government gifted Kisan Call Centres (KCC) are functioning the all over India which give answers to the farmer queries in local languages to this toll free number 1800-180-1551. Grameen Phone is a commercial operation providing cellular services in both urban and rural areas of India, with approximately 40,000 customers. A pilot programme of Grameen Phone, through the Grameen Bank and a wholly owned subsidiary called Grameen Telecom, is enabling women members of the Grameen Bank’s revolving credit system to retail cellular phone services in rural areas. This instrument is more than a means of communication and it is being used as a weapon for empowerment and fight poverty. Mobile advisory system have been developed and utilized for transfer of agricultural technologies for sustainable development across the world. The findings of the different mobile based studies conducted across the world have reviewed and presented for replicating the suitable models in similar situation for effective dissemination of the technologies. It is concluded that mobile platform is only tool to reach the last mile connectivity especially in rural areas for delivering need based technologies in time.

What Maria Exposed to Us

First paragraph: It has been nearly two years since Hurricane Maria unleased her fury on Puerto Rico, Dominica, and the U.S Virgin Islands in September 2017. Hurricane Maria caused an estimated US$94 billion in damages, with the majority of those damages reported in Puerto Rico (Mercy Corps, 2019). It is estimated that 2,975 Puerto Ricans lost their lives because of the hurricane, though the eventual death toll may have reached 4,000 (Mercy Corps, 2019). When Maria hit, the islands were still in recovery from Hurricane Irma, which had struck the north side of the main island just days before. The entirety of the archipelago, all 3.4 million resi­dents, lost power after Maria, and it was estimated that Puerto Ricans, on average, went 84 days without power, 68 days without water, and 41 days without cellular phone service (Mercy Corps, 2019). Overnight, Puerto Rico became discon­nected from the outside world. Prior to the 2017 hurricanes, Puerto Rico was already grappling with widespread poverty and a crumbling infrastructure after years of disinvestment and structural adjust­ment.[1] These inequalities left Puerto Ricans with a host of challenges related to their wellbeing. For instance, according to the National Resources Defense Council, in 2015, 99.5% of Puerto Ricans were served by community water systems that violated the Safe Drinking Water Act (NRDC, 2017). Before Maria, 1.5 million Puerto Ricans were food insecure, with children experiencing food insecurity at a rate of 56%—triple the U.S. average (Bread for the World, 2019). [1] Structural adjustment refers to the delivery and administration of loans to states or regions in economic crisis, often loaned by institutions like the World Bank or International Monetary Fund. These loans are given on the condition of economic reforms. Structural adjustment is widely critiqued as a mechanism that deepens poverty and increases dependency.

Getting Smart About Phones: New Price Indexes and the Allocation of Spending Between Devices and Services Plans in Personal Consumption Expenditures

This paper addresses two measurement issues for mobile phones. First, we develop a new mobile phone price index using hedonic quality-adjusted prices for smartphones and a matched-model index for feature phones. Our index falls at an average annual rate of 17 percent during 2010-2018, close to the rate of decline in the price index used in the GDP Accounts. Given relatively flat average prices over this period, our index points to substantial quality improvement. Second, we propose a methodology to disentangle purchases of phones and wireless services when they are bundled together as part of a long-term service contract. Getting the allocation right is especially important for real PCE because the price deflators for phones and wireless services exhibit very different trends. Our adjusted estimates suggest that real PCE spending currently captured in the category Cellular Phone Services increased 4 percentage points faster than is reflected in published data.

Communication, information seeking, and evacuation plans for a disaster using Community Assessment for Public Health Emergency Response in the Gulf Coast counties of Alabama and Mississippi, 2011

To determine communication, information seeking, and evacuation behaviors of coastal residents in a disaster-prone area. A two-stage, probability sampling design to select 210 households in each assessment area was used. Data were analyzed using a weighted cluster analysis to report projected households for each assessment area. Public health services areas of coastal Alabama and Mississippi. Eligible respondents were 18 years of age or older, had lived in the community for at least 30 days, and were residents of the selected household. Evacuation propensity, primary communication forms, primary information forms, and special needs. Most coastal residents would evacuate if recommended by public health authorities. Fewer residents had landlines (45.9-58.8 percent) compared to residents using cellular or mobile phone service only (84.3-95.8 percent), and these residents were significantly older compared to non-landline owning residents. Most residents own pets (61.9-70.1 percent). Our assessment suggests that the majority of Alabama and Mississippi coastal residents plan to evacuate during a disaster if recommended by public health authorities. However, public health authorities should strive to evaluate multiple forms of communication to disseminate disaster preparedness and response messages to reach all vulnerable residents, especially in situations where electric services might be compromised. Emergency preparedness personnel should also be prepared for a large pet population in the event of an evacuation.

Analysis of Perceptions of Customers of Cellular Phone Users in India: Study with Prepaid Service Customers and Post Paid Customers Demographic Factors

The primary objective of the study is to find out and analyze the customer perceptions on cellular phone services in India. Cellular phones are become the part of the life and the various barriers in the obtaining and usage of cellular services are lack of awareness, cost factor, perceptions of the customers on cellular phones etc. In addition the service quality, customer care, market competition brings lot of instability and reliability of the services. In turn it makes further confusion among the users. It paves an opportunity of providing limited services in the selective areas. It leads to a wide gap in the service quality and reliability between the urban and semi urban areas. It gives an opportunity to the researcher to survey on the facts and perceptions of the cellular phone users to find out the real situation and to suggest appropriate suggestions to overcome the issues in the market expansion and to improve the service quality of the cellular phone services in the sample area. To do this, the researcher selects a comparative approach. The data is collected by preparing a structured questionnaire and collected from the cellular phone users in the sample area. The study centered, in comparing the customers perceptions towards cellular phone services provided by the different operators in the states of India. The customers are from both urban and semi-urban places of India. In addition, customers were also classified on the basis of the type of services usage (i.e., post paid or pre paid). The basic parameters used for the purpose of comparing their perceptions are purpose of usage. The study has taken the demographic factors of respondents for analysis.

Consumer Inattention and Bill-Shock Regulation

For many goods and services such as electricity, health care, cellular phone service, debit-card transactions, or those sold with loyalty discounts, the price of the next unit of service depends on past usage. As a result, consumers who are inattentive to their past usage but are aware of contract terms may remain uncertain about the price of the next unit. I develop a model of inattentive consumption, derive equilibrium pricing when consumers are inattentive, and evaluate bill-shock regulation requiring firms to disclose information that substitutes for attention. When inattentive consumers are sophisticated but heterogeneous in their expected demand, bill-shock regulation reduces social welfare in fairly-competitive markets, which may be the effect of the Federal Communication Commission's recent bill-shock agreement. If some consumers are attentive while others naively fail to anticipate their own inattention, however, then bill-shock regulation increases social welfare and can benefit consumers. Hence, requiring zero-balance alerts in addition to the Federal Reserve's new opt-in rule for debit-card overdraft protection may benefit consumers

'Typical ' Morphology System of Language Advertising of Cellular Services

Advertising is a form of expression to convey ideas through a language either orally or in writing. Advertising that is conveyed in writing is sometimes combined with pictures and colors. Advertising aims to encourage and persuade the public that is interested in either the products or services offered. In other words, advertising must have a persuasive element. With their sophisticated networks, cellular phone service companies offer a wide array of excellence in attracting their customers. Various advantages offered by cellular phone service companies are conveyed through a language. The language containing creative dictions is always used by these companies in attracting their customers. This study aims to identify what elements make up the morphological system of advertising language used by the cellular phone service companies. From the analysis, it can be concluded that the morphological system of advertising language in the cellular phone services has both qualitative and quantitative elements which are presented in an interesting, creative, and persuasive way to depict the simplicity, inexpensiveness, completeness, security, frugality, peacefulness of the services themselves. The study also found that the morphological system of the advertising language has specific phonemic forms in their morphological process, specific morphemic forms in their morphological process, special morphemes which are specifically used in the field of cellular phone, specific morphological process, and specialized dictions. They are the typical forms of morphological system of the advertising language in the cellular phone services.

An economically-oriented neural network approach for optimum estimation of cellular phone subscriptions in noisy and nonlinear markets

Cellular phone subscriptions have been increased significantly in recent years through a complex and uncertain pattern. This study estimates the complex and uncertain behavior of cellular subscriptions through an adaptive economically oriented neural network. The superiority of the proposed neural network to fuzzy and conventional regression is shown by comparing mean absolute percentage of error, analysis of variance and Tukey’s test results. Four economic indicators including population, gross domestic production, receipt income per capita and subscriptions of previous year are considered as the input data, and subscriptions to cellular phone service per 100 people is considered as the output data. To show the superiority and applicability of the neural network, the data with respect to the inputs and output have been collected from 51 countries on 5 continents for 15 years (1990–2004). According to the results, in complex and nonlinear markets, the neural network is identified as the preferred model for estimation of numbers of cellular phone subscribers.

How Customer Loyalty Model Be Operative? A study of Cellular Phone Service Providers in Pakistan

The idea of this study is raised because of tough competition in cell phone industry of Pakistan. In this scenario, every organization after retaining customer tries to make him/her loyal. The loyalty, which has rigorously investigated, empirically tested with different combination of variables, which collectively help in making the customer loyal. Data were collected through 508 questionnaires. Respondents were pre-paid cell phone customers. Data was analyzed via factor loading and reliability of variables. Structural Equation Modeling (SEM) technique was used for the testing of hypotheses. Loyalty model was found significantly responsive for cellular phone services in Pakistan. Perceived service quality, satisfaction, trust and image have chained link of positive affects, which leads to loyalty of customers in the telecom sector of Pakistan. Customers do not take effect of perceived service quality. However, it is service quality, which satisfies customer through image of the organization. This loyalty model is more preferably applicable in the industry where competition is tough and switching rate is high. In future researches, this model can be tested across the culture. Moreover, more variables can be added to strengthen the loyalty model.

Intra-Household Effects on Demand for Telephone Service: Empirical Evidence

I present a game-theoretical model to empirically analyze the consumption interac-tions among household members. Although multiple Nash equilibria of consumption decisions may exist in a household, model parameters are pointwise identified for households with only two members. I propose a semiparametric maximum likelihood estimator and apply it to study the subscription decision for cellular phone service in Taiwan. On average, a consumer’s probability of subscribing to cellular service rises 14 percentage points when the other household member chooses to subscribe, suggesting the existence of intra-household network effects. Moreover, intra-household effect is heterogeneous among households. It increases in household income, but decreases in the number of children and the age difference in a household.

Intra-household effects on demand for telephone service: Empirical evidence

Knowing the determinants of consumption decisions is important for targeted marketing. This paper proposes a method to study household adoption of network goods. I empirically investigate the factors which affect the interactions among household members in the choice of telephone service using a game-theoretical model. The proposed semiparametric maximum likelihood estimator accounts for potential multiple Nash equilibria. I apply the method to study the subscription decisions for cellular phone service in Taiwan. On average, a consumer’s probability of subscribing to cellular service rises 13 percentage points when the other household member chooses to subscribe, suggesting the existence of intra-household network effects. Moreover, the intra-household effect is heterogeneous among households. It increases in household income, but decreases in the number of children and the age difference within a household. Firms can substantially increase the effectiveness of a marketing strategy by targeting on the observed consumer characteristics.

QoS-aware path switching for VoIP traffic using SCTP

Voice over Internet protocol (VoIP) has been a prevalent multimedia service nowadays. It allows us to transmit voice data over IP networks. However, quality of service (QoS) is a major challenge to VoIP services. It must provide similar quality to traditional public switched telephone network or cellular phone services. Therefore, QoS related protocols have become important for real-time applications. Multi-protocol label switch (MPLS) is one of the important techniques to improve the network performance from QoS point of view. It employs label swapping to speed up packet forwarding. However, when a large number of users utilize VoIP services, the network congestion issue still exists. It causes delay, jitter and packet loss that affect VoIP QoS. In this paper, we propose a QoS-aware path switching strategy by using stream control transmission protocol (SCTP) in MPLS network to improve the VoIP traffic. This was done by employing SCTP selective acknowledgment mechanism to report the transmission parameters of primary path and to determine the criteria to switch to backup path. Simulation results show significant improvement in VoIP QoS.

Marketing activity, blogging and sales

The recent growth of consumer-generated media (CGM), also known as “new” media, has changed the interaction between consumers and firms from being unidirectional to being bidirectional. However, CGM are almost always accompanied by traditional media (such as TV advertising). This research addresses the critical question of whether new and traditional media reinforce or damage one another's effectiveness. This question is important because traditional media, in which a manufacturer creates and delivers content to consumers, consume a firm's resources. In contrast to these paid media, new media (in which consumers create content and this content is exchanged between other consumers and potentially between manufacturers) are primarily available for free. This question becomes even more salient when new product launches are involved, as firms typically allocate approximately half of their marketing budgets to support new products.One of the most prevalent forms of new media is blogging. Therefore, we assemble a unique data set from Japan that contains market outcomes (sales) for new products, new media (blogs) and traditional media (TV advertising) in the movie category. We specify a simultaneous equation log-linear system for market outcomes and the volume of blogs. Our results suggest that new and traditional media act synergistically, that pre-launch TV advertising spurs blogging activity but becomes less effective during the post-launch period and that market outcomes have an effect on blogging quantity. We find detailed support for some of these results via a unique and novel text-mining analysis and replicate our findings for a second product category, cellular phone service. We also discuss the managerial implications of our findings.
