Fuzzy-set Qualitative Comparative Analysis (fsQCA): Guidelines for research practice in Information Systems and marketing
2021
Abstract The increasing interest in fuzzy-set Qualitative Comparative Analysis (fsQCA) in Information Systems and marketing raises the need for a tutorial paper that discusses the basic concepts and principles of the method, provide answers to typical questions that editors, reviewers, and authors would have when dealing with a new tool of analysis, and practically guide researchers on how to employ fsQCA. This article helps the reader to gain richer information from their data and understand the importance of avoiding shallow information‐from‐data reporting. To this end, it proposes a different research paradigm that includes asymmetric, configurational‐focused case‐outcome theory construc…

Understanding the use of mobile phones in the agricultural sector in rural Indonesia: using the capability approach as lens
2012
This study aims to investigate the use of mobile phones in the agricultural sector and its possible contributions to development of developing countries, with special reference to Indonesia. In our interpretive work, the capability approach is used as a lens, and the study is informed by data from interviews with various actors and field observations. The paper unearths the pattern of use of mobile phones among farmers in their professional network and shows that ownership and use of mobile phones varies, depending on the farmers' location in the network hierarchy. The study further unveils that the conversion factors play a significant role in order to realise achievement (functionings) fr…
Improved resource allocation strategy in SU-CoMP network
2011
Coordinated multi-point transmission and reception (CoMP) for single user, named as SU-CoMP, is considered as an efficient approach to mitigate inter-cell interference in orthogonal frequency division multiple access (OFDMA) systems. Two prevalent approaches in SU-CoMP are coordinated scheduling (CS) and joint processing (JP). Although JP in SU-CoMP has been proved to achieve a great link performance improvement for the cell-edge user, efficient resource allocation (RA) on the system level is quite needed. However, so far limited work has been done considering JP, and most existing schemes achieved the improvement of cell-edge performance at cost of the cell-average performance degradation …
Adaptive Medium Access Control for Distributed Processing in Wireless Sensor Networks
2019
Signal and information processing tasks over Wireless Sensor Networks can be successfully accomplished by means of a distributed implementation among the nodes. Existing distributed schemes are commonly based on iterative strategies that imply a huge demand of one-hop transmissions, which must be efficiently processed by the lower layers of the nodes. At the link layer, general purpose medium access (MAC) policies for wireless communications usually focus on avoiding collisions. These existing approaches result in a reduction of the number of simultaneous transmissions, and an underutilization of the channel as a consequence. This leads to a decrease in the performance of the distributed ta…
Everyday Appropriations of Information Technology: A Study of Creative Uses of Digital Cameras
2011
Repurposive appropriation is a creative everyday act in which a user invents a novel use for information technology (IT) and adopts it. This study is the first to address its prevalence and predictability in the consumer IT context. In all, 2,379 respondents filled in an online questionnaire on creative uses of digital cameras, such as using them as scanners, periscopes, and storage media. The data reveal that such creative uses are adopted by about half of the users, on average, across different demographic backgrounds. Discovery of a creative use on one's own is slightly more common than is learning it from others. Most users discover the creative uses either completely on their own or wh…
Data offloading and task allocation for cloudlet-assisted ad hoc mobile clouds
2016
Nowadays, although the data processing capabilities of the modern mobile devices are developed in a fast speed, the resources are still limited in terms of processing capacity and battery lifetime. Some applications, in particular the computationally intensive ones, such as multimedia and gaming, often require more computational resources than a mobile device can afford. One way to address such a problem is that the mobile device can offload those tasks to the centralized cloud with data centers, the nearby cloudlet or ad hoc mobile cloud. In this paper, we propose a data offloading and task allocation scheme for a cloudlet-assisted ad hoc mobile cloud in which the master device (MD) who ha…
The Construction of Ideological and Political Education in Higher Vocational Schools Based on Smartphone Carriers
2022
In the age of technology, artificial intelligence has reached new heights. The growth of the educational system has also evolved with technological growth. In this research, people are going to study the construction of ideological and political education in higher vocational schools based on smartphone carriers. The use of smartphones is becoming more common and unavoidable due to the growth of Internet technology, cloud technology, and wireless technology. The availability of 4G and 5G technologies supports all the relevant and nonrelevant industries to utilize this growth. The field of education has also adapted to this new age of technology by implementing online classes that replace cl…
“La victoria de la técnica”, según Ortega y Gasset (una alternativa a Heidegger)
2013
ABSTRACT Ortega y Gasset's "Mediation on Technique" is part of his historical diagnostic of modern and contemporary life, wich we can resume by means of the expression "the victory of technique". But, secondly, Ortegian reflections upon technique is decisive for understanding human being, its reason and universal history. And, thirdly, it represents an alternative to the herdeggerian way, not only in relation to technique, but to philosophical thinking in general, although wothout accepting naturalism as way out. RESUMEN “Meditacion de la tecnica” de Ortega y Gasset forma parte del diagnostico historico de la vida moderna y contemporanea, que puede resumirse mediante la expresion “la victo…
Gray visiting Motzkins
2002
We present the first Gray code for Motzkin words and their generalizations: k colored Motzkin words and Schroder words. The construction of these Gray codes is based on the observation that a k colored Motzkin word is the shuffle of a Dyck word by a k-ary variation on a trajectory which is a combination. In the final part of the paper we give some algorithmic considerations and other possible applications of the techniques introduced here.
