Business Models and Economic Approaches for Recovering Energy from Wastewater and Fecal Sludge

2015

Universal access to water, sanitation and energy services are key challenges in low income countries. The conventional model of providing water, sanitation and waste disposal as a social service is no longer viable because national authorities lack financial and human resources for operation and maintenance and for addressing the sanitation needs locally. Human excreta and wastewater represent resources that can be used to generate new income and support livelihoods through use as a source of energy. The reduction, removal and reuse of wastes must become financially feasible and economically profitable and yield high returns. This requires innovative and sustainable business models and fina…

On Obtaining Classification Confidence, Ranked Predictions and AUC with Tsetlin Machines

2020

Tsetlin machines (TMs) are a promising approach to machine learning that uses Tsetlin Automata to produce patterns in propositional logic, leading to binary (hard) classifications. In many applications, however, one needs to know the confidence of classifications, e.g. to facilitate risk management. In this paper, we propose a novel scheme for measuring TM confidence based on the logistic function, calculated from the propositional logic patterns that match the input. We then use this scheme to trade off precision against recall, producing area under receiver operating characteristic curves (AUC) for TMs. Empirically, using four real-world datasets, we show that AUC is a more sensitive meas…

The value proposition of food delivery apps from the perspective of theory of consumption value

2021

Purpose The theory of consumption values (TCV) has successfully explained much consumer choice behavior, but few studies have investigated the values that drive food-delivery application (FDA) use. This study aims to bridge this gap by extending the TCV to the FDA context to examine food consumption-related values and interpreting and rechristening generic consumption values to adapt the TCV to the FDA context. Design/methodology/approach An explorative mixed-method research approach was taken to conduct focus group discussions with 20 target users to develop the questionnaire and then administer it for a cross-sectional survey (pen and pencil) to FDA users aged 22–65 years; 423 complete r…

Introduction to ICT Enabled Services Minitrack

2015

The purpose of the minitrack is to draw researchers’ attention to ICT Enabled Services for both Consumers and Enterprises. It provides a discussion forum for researchers interested in fostering a service-based approach to these areas as well as an opportunity to present and debate both design and theory-based solutions to the problems facing industry in the deployment of ICT enabled services [1-4]. In a broad sense, ICT enabled services can be defined as [1]: “..systems that enable value co-creation through the development and implementation of information and communication technology enabled processes that integrate system value propositions with customer value drivers.”

Exploring End-User Reactions to Variations in the Value Proposition of Value Services

2009

Value services are most often innovations where endusers have little or no experience from using the service. Designing business models for such services is a challenging task including the design of value propositions that are perceived and interpreted through end-users’ complex value assessments. This study presents the results from a study of end-user value assessments of value proposition variations for two value services – mobile VoIP and multi play services. The study suggests a method for investigating end-user reactions to value proposition variations and presents the effects of these variations on attribute perceptions and value drivers. The main contribution of the study is method…

Current Software-as-a-Service Business Models: Evidence from Finland

2012

This paper characterizes the business models of Software-as-a-Service (SaaS) firms based on their value proposition, customer segments, revenue streams, and customer relationship, and analyzes interconnections of these business model elements. The target set of 163 Finnish SaaS and ASP firms was first compared to other software firms and then clustered into four clusters based on indicator data of their business model elements. The comparison reveals that the SaaS and ASP firms have smaller customer and transaction sizes than software firms in general. The resulting classification reveals two different configurations, a pure-play SaaS model and an enterprise SaaS model, and the typical fact…

An exploration of reciprocity between female athletes and their coach in elite junior swimming: a shared reality theory perspective

2021

Based on the proposition that the relationship between a coach and athlete is at its best when both parties contribute to enhancing its quality, the present study sought to investigate if Shared Reality Theory could provide new insights on the topic. Specifically, the purpose of the present study was to explore: (a) how a shared reality is established, or fails to be established, over the course of the sporting partnership between athletes and their coach; and (b) how the presence of a shared reality (or not) in the coach-athlete relationship is related to the experienced quality of the relationship between athletes and their coach, as recorded over time. Narrative inquiry, embedded within …

2016

Abstract Public Service Platforms (PSPs) are a new type of technology platform. They are based in the philosophy of New Public Management (NPM) and support public services for citizens in quasi-markets. This article increases our understanding of the business models behind these PSPs in terms of their Value Propositions, structures, networks, and financing. We interviewed representatives from 14 PSP providers in four public sectors in Sweden: education, healthcare, elder care, and public pensions. We identified a “Traditional view” with its focus on public agencies and neutral information and an “Emerging view” that includes dialogues, user evaluations, long-term perspectives on choice, pro…

Logic for accumulation of design science research theory

2014

The paper introduces a structured logic for iterative and incremental accumulation of a design theory during a research project and across research programs. The logic is proposed to help researchers understand the links between parallel search spaces related to a particular design and linking to theoretical knowledge bases produced by previous search processes. The proposition rests on the notion that representing the structure and logic of design science research (DSR) theory using CIMO enables the elements of the knowledge base to be more easily evaluated, combined, and transferred between related search spaces. We view DSR theory development as an iterative and incremental social proces…

Quasivarieties of Algebras

2001

This chapter plays a twofold role in the book. Firstly, the chapter surveys basic facts about quasivarieties of algebras. These facts are widely utilised in the subsequent chapters devoted to algebraizable logics. Secondly, the chapter shows how the methods initially elaborated for protoalgebraic sentential logics in the first part can be also applied in the area of equational logic. Most of the results presented in this chapter are proved by way of adapting the purely consequential methods of sentential logic to the needs of the (quasi) equational systems associated with quasivarieties of algebras.
