Abstract:

We present several ideas of increasing complexity how to translate default theories to normal logic programs that make direct use of the deductive capacity of logic programming. We show the limitations of simple, ad hoc approaches, and arrive at a more general construction; its main property is that the answer substitutions computed by the logic program via its standard operational semantics correspond exactly to the extensions of the default theory.

Abstract:

Purpose Work integration social enterprises (WISEs) address the chronic unemployment of disadvantaged populations. However, WISEs face challenges, in part, because they embody both social mission and market logics which potentially contradict one another. The purpose of this paper is to investigate how the founders of WISEs perceive the relationship between logics and how they manage any resulting tensions, to help determine if they are effective vehicles for alleviating unemployment. Design/methodology/approach This study used in-depth interviews with social entrepreneurs in nationally recognized WISEs to assess how they perceived and managed logic tensions. Findings A total of eight out of the ten WISEs emphasized one dominant logic and did not perceive significant internal conflict. Only two cases experienced prolonged and ultimately irreconcilable tensions between their social mission and market goals, when social entrepreneurs were guided by the blended logics of providing training and services to disadvantaged populations within a for-profit legal form. Research limitations/implications Future research is required to determine the generalizability of these findings due to small sample size, an exclusive focus on the founder’s perspective and an exclusive focus on WISEs. Practical implications Findings contribute to greater understanding of logic tensions in WISEs and the opportunities and limitations that result from aligning dominant logic(s) and organizational form. Originality/value This research suggests that the founders of WISEs perceive market and social mission logics as options to be selected, and that WISEs struggle to succeed as organizations with two dominant logics. The market appears as yet unprepared to support singlehandedly organizations with a social mission of work integration.

Abstract:

Since the end of the XX century we are witnessing a practical, or cognitive, turn in logic. Drawing on enormous achievements brought about by the mathematical turn that started more than a hundred years ago, logic now has came back to its Artistotelian roots as an instrument by which we come to know anything. The re-forged alliance between logic – now well equipped with sophisticated formal tools – and psychology results in more and more substantial developments in studies on human reasoning and problem solving. To reap the fruits of this alliance we need to be aware that it leads to a shift in focal points of interest of such studies as well as to expansion of their methodological repertoire. In this paper I argue that the practical turn in logic results in: (1) the concept of error becoming crucial for formal modeling of human reasoning processes, (2) prescriptive perspective, which takes into account human limitations in information processing, becoming the most interesting vantage point for such research and (3) triangulation of formal methods, quantitative approach and qualitative analyses becoming most effective methodology in formal modeling studies.

Abstract:

Purpose This paper aims to understand how competing logics can co-exist in the organizational field of Indian microfinance. Design/methodology/approach The paper uses the theoretical lens of an organizational field to understand the composition of the microfinance field. Using the definition of an organizational field, key players in Indian microfinance are identified and their interactions within the field are analysed to understand the emergence and co-existence of multiple logics. The data used for this paper are collected from published work on Indian microfinance. Findings The co-existence of competing logics is sustained through the creation of two sub-fields within Indian microfinance. Each of the sub-field is dominated by one institutional logic. The field originated in developmental logic of microfinance and gradually adopted the banking logic post-2000. The sub-fields are dominated by different organizational forms with different nature of interaction within the field. Research limitations/implications Actors within the field would experience institutional complexity with lesser intensity because of the existence of two distinct sub-communities with individual logic. Dual logics can sustain itself independently provided these are embedded in two different sub-communities. Despite the emergence of a new logic, the previous logic can still remain relevant given the enabling support from institutional infrastructure. Practical implications The manifestation of development and banking logics through practices and the belief system in Indian microfinance would offer useful insights for social entrepreneurs balancing the dual goals of hybrid organizations. Due to the sub-communities, a professional working with different forms of organization would experience little pressure to adjust to diverse logic and would also experience no or little identity conflict. Originality/value This paper focuses on the microfinance sector in India as an organizational field and explores the mechanism of co-existence of the dual goals of microfinance at the field level.

Abstract:

Don DeLillo’s early novels explore the relationship between formal logic and literary form. In End Zone, DeLillo uses tautology as a linguistic tactic of diminishment to advance a larger aesthetic strategy of repleteness. The novel says less to show more. As a result, End Zone, like many of DeLillo’s other early novels, frequently represents states of silence and unspeakability. DeLillo’s early fiction shares these concerns with Ludwig Wittgenstein’s early philosophy, particularly the remarks on tautology, silence, and the limits of language in Tractatus Logico-Philosophicus. In their conclusions, End Zone and the Tractatus analogously seek to undo themselves to overcome the inherent limitations of logic and language.

Abstract:

AbstractMotivated by the search for a logic for polynomial time, we study rank logic (FPR) which extends fixed-point logic with counting (FPC) by operators that determine the rank of matrices over finite fields. WhileFPRcan express most of the known queries that separateFPCfromPtime, almost nothing was known about the limitations of its expressive power.In our first main result we show that the extensions ofFPCby rank operators over different prime fields are incomparable. This solves an open question posed by Dawar and Holm and also implies that rank logic, in its original definition with a distinct rank operator for every field, fails to capture polynomial time. In particular we show that the variant of rank logic${\text{FPR}}^{\text{*}}$with an operator that uniformly expresses the matrix rank over finite fields is more expressive thanFPR.One important step in our proof is to consider solvability logicFPSwhich is the analogous extension ofFPCby quantifiers which express the solvability problem for linear equation systems over finite fields. Solvability logic can easily be embedded into rank logic, but it is open whether it is a strict fragment. In our second main result we give a partial answer to this question: in the absence of counting, rank operators are strictly more expressive than solvability quantifiers.

Abstract:

Several studies have shown that pioneers have long-lived market share advantages and are likely to be market leaders in their product categories. However, that research has potential limitations: the reliance on a few established databases, the exclusion of nonsurvivors, and the use of single-informant self-reports for data collection. The authors of this study use an alternate method, historical analysis, to avoid these limitations. Approximately 500 brands in 50 product categories are analyzed. The results show that almost half of market pioneers fail and their mean market share is much lower than that found in other studies. Also, early market leaders have much greater long-term success and enter an average of 13 years after pioneers.

Abstract:

Purpose The purpose of this study is to develop a service logic oriented framework for business model development. “Service logic” covers the basic principles of the three contemporary customer value focused business logics: service-dominant logic, service logic and customer-dominant logic. Design/methodology/approach This study is based on an empirical qualitative research and deployed the focus group method. The data are generated in a series of interactive co-creative focus group workshops involving both practitioners and academics. Findings As the outcome, a new tool was developed, called Service Logic Business Model Canvas. The new canvas is a modified version of the original Business Model Canvas (Osterwalder and Pigneur, 2010). Research limitations/implications This study adopts service logic in business model thinking and increases knowledge on how to keep the customer needs in the centre of business model development. Practical implications The developed canvas makes the theory of service-dominant logic tangible and easily applicable in practice. It enables service innovation truly based on customer value by ensuring that the customer is in the centre of all the elements of a business model. It can function both as a rapid prototype of a new business model and as a communication tool that quickly illustrates the company’s current business model. It can also help in creating a customer-centred business culture. It is designed to be applied to each customer profile separately, thus enabling a deeper understanding of the customer logic of each relevant profile. Originality/value Earlier business model frameworks tend to be provider-centric and goods-dominant, and require further development and adaptation to service logic. This study adopts service logic in business model thinking. It embeds the true and deep customer understanding and customer value in each element of the business model, and contributes to both business model and service-dominant logic literature.

Abstract:

Purpose This paper aims to investigate the accounting logic inscribed in the SAP enterprise resource planning (ERP) system and how this accounting logic becomes effective in organizations. The authors draw on the notion of accounting logics by mobilizing the institutional logics literature (Thornton et al., 2012). Accordingly, accounting logics are conceptualized as crucial underlying design principles consisting of a system of beliefs, assumptions and ideas how accounting systems should be designed. Design/methodology/approach The authors adopt a qualitative case study approach conducted in a manufacturing company, hereafter called Wood Plc. The primary data source is qualitative research interviews. Secondary data, such as internal documents, were collected to increase validity and reliability through data triangulation (Ahrens and Chapman, 2006; Scapens, 2004). Findings The paper demonstrates how a particular accounting logic – the Germanic accounting logic – gets diffused throughout the organization by the means of the SAP ERP system, and creates challenges for management accounting practices in local entities. The contribution of the paper is to show that ERP systems can foster the diffusion of a specific accounting logic, which is inherently linked to the SAP system, and which enables a specific version of accounting to work in an organization. Research limitations/implications This paper could be viewed as an extreme case of a German organization using the SAP ERP system with its Germanic accounting logic inscribed to make a German accounting logic work in the entire organization. Consequently, further research could unpack the relationship between accounting logics, ERP systems, accounting systems and their use by studying not only different empirical settings with respect to the organizational context but also the ERP software used by organizations. Practical implications This paper aims to raise the awareness of practitioners of the conceptual underpinnings inscribed in the SAP accounting modules while at the same time pinpointing the potential challenges of implementation generated by the accounting logics. Originality/value The paper complements existing studies on accounting and ERP systems by bringing the accounting logic inscribed in the SAP ERP system to the fore. More precisely, this paper shows that in the wake of SAP ERP implementation, the organization studied spread its assumptions and beliefs on accounting, which are manifested in the Germanic accounting logic inscribed in the SAP ERP system, in the organization. This invoked particular challenges in non-Germanic subsidiaries in making accounting work.

Abstract:

Purpose – This study investigates in depth how decision-making of different organisational members is shaped by various management control systems (MCSs) that reflect different institutional logics, how the entire organisation deals with the arising institutional complexity and which role different management controls as a system play in such situations. Design/methodology/approach – A case study was conducted on a German Mittelstand firm whose MCSs were shaped by three different logics over time: a family logic, a stakeholder logic and a shareholder logic. Findings – This paper shows how different actors of an organisation confronted with institutional complexity used selective coupling of different MCS components and compartmentalizing MCS components to deal with clashing institutional logics. Thereby, it was possible for the actors to balance different sub-communities within the firm that were shaped by conflicting but yet complementary logics that were required for organisational survival. Research limitations/implications – This study contributes to the understanding of how an MCS can be exploited for organisational structural responses to multiple logics. Due to this research design, the present study deals with challenges of ex post rationalization. Practical implications – The results show options for organisational leaders to deal with different kind of worldviews (i.e. logics) that shape employees’ behaviour. Particularly, this paper explains how leaders can restructure their MCSs to influence human behaviour in times of radical change. Originality/value – This paper contributes to the literature on MCSs by showing what role MCSs play in structural responses to institutional complexity.

Abstract:

Purpose The purpose of this study is to empirically investigate the impact of institutional pressures, institutional logics and institutional complexity on Sustainable Supply Chain Management (SSCM) practices across mixed public and private sector supply chains. Design/methodology/approach Multi-case study data were collected from three tiers of food and catering supply chains: the customer/consumer tier; focal public sector UK Universities; and private sector suppliers/contractors. Findings The findings indicate that: normative and mimetic pressures are more prevalent in focal Universities, compared to suppliers; there is typically no single dominant logic across these supply chains; and the multiplicity of institutional logics (e.g. sustainability logic versus financial logic) increases institutional complexity. Therefore, in the typical case of homogeneity in terms of institutional pressures and logics, e.g. with a dominant sustainability logic throughout the supply chain, radical change in SSCM practices is facilitated. In contrast, in the more typical case when there is heterogeneity, with competing logics at different supply chain tiers, this limits SSCM to more incremental changes in practices. Research limitations/implications This study is limited to three tiers of the food and catering supply chains of UK Universities. Practical implications To aid in the successful implementation of SSCM, this study suggests a need for managers to develop an initial understanding of the prevailing institutional logics and pressures at different tiers of the supply chain. Social implications A number of the SSCM practices studied address social sustainability. Originality/value No previous studies have empirically investigated the impact of institutional complexity in the context of SSCM practices across supply chains, involving both mixed public and private sector organisations.

Abstract:

PurposeThe purpose of this paper is to examine the influence of shared cognitive frames, in particular, that of institutional logics, on the deployment and use of performance measurement systems (PMSs) in the public sector.Design/methodology/approachUsing novel priming techniques derived from behavioral and social psychology, three institutional logics – the public, market-managerial and professional logics – are differentially surfaced in three independent experimental groups. The influence of these primed institutional logics on performance measurement use preferences are then empirically assessed using appropriate analysis of variance techniques.FindingsContrary to theoretical predictions, the paper reveals logic congruence regarding some uses of PMSs in the public sector, and divergence regarding others. Individuals applying a public logic were more likely to propose performance measurement use for strategic planning or strategic alignment; while those applying a professional logic were more likely to propose performance measurement use for learning, compared to otherwise primed individuals.Research limitations/implicationsConsidering the sample size and the novelty of the priming tools, it is feasible that other potentially significant effects may have been missed.Originality/valueThe paper addresses a gap in literature regarding the influence of shared cognitive frames on performance measurement use in public sector organizations. The paper further presents priming techniques embedded within an experimental design as an appropriate method for the micro-level study of attitudes, preferences and judgments in the public sector.

Abstract:

Purpose The purpose of this paper is to explore the logics that expert entrepreneurs use when faced with a critical incident threat. Design/methodology/approach Attempts have been made to define “entrepreneurial logic”. This paper is influenced by Sarasvathy’s work on high-performance entrepreneurs, which finds that when faced with uncertainty entrepreneurs employ unconventional logic, and encompasses later research acknowledging social contexts where entrepreneurs operate. A typology of decision-making logics is developed, taking into account the situation of crisis. Seven expert entrepreneurs who faced crisis and, despite this, are still successfully operating businesses were interviewed. The paper develops a critical incidents methodology. Findings Experienced entrepreneurs were found to tend towards causal logic when “the stakes were high” and the decision may affect the survival of their business. They also weigh up options before acting and tend to seek advice from trusted “others” within their network before or after they have made a decision. A mixture of causal and intuitive logic is evident in decisions dealing with internal business problems. Research limitations/implications The decisions that entrepreneurs make shape and define their business and their ability to recover from crisis. If researchers can develop an understanding of how entrepreneurs make decisions – what information they draw upon, what support systems they use and the logic of their decision-making and rationalisation – then this can be used to help structure support. Originality/value By exploring decision-making through critical incidents we offer an innovative way to understand context-rich, first-hand experiences and behaviours of entrepreneurs around a focal point.

Abstract:

PurposeParticipatory budgeting (PB) is considered a suitable tool for supporting and promoting citizen engagement in government work. Previous studies of PB have deeply investigated its design and effects, but paid little attention to the underlying logics of adopting and implementing PB. The purpose of this paper is to, accordingly, investigate the development over time of the institutional logics of PB and attempt to explain their effect on PB.Design/methodology/approachUsing a longitudinal multiple case study design, this research analyzes the evolution of institutional logics over time and across five municipalities in Italy. The analysis integrates documents with interviews conducted at two times to investigate the evolution of PB logics.FindingsThe development of PB is characterized by the spread of two emerging logics–i.e. managerial and community-building logics–that replace or coexist with the traditional political logic. Indeed, these different logics can coexist within governments, with different degrees of conflict or coexistence, resulting in what can be considered a hybrid logic.Research limitations/implicationsAlthough the number of examined cases is limited, this research elaborates an original conceptual approach and provides new insights that could help in better designing and implementing PB.Originality/valueThis research builds knowledge of PB by shedding light on its different logics, linking them to diverse specific models of PB and exploring their changes over time.

Abstract:

PurposeThe purpose of this paper is to examine how, and by whom, institutional logics are determined in the action of sustainable organisation. The authors analyse a supply chain network structure to understand how multiple stakeholders' perceptions of sustainability emerge into a dominant logic and diffuse across an organisational field.Design/methodology/approachStakeholder network theory provides novel insights into emerging logics within a chocolate supply chain network. Semi-structured interviews with 35 decision-makers were analysed alongside 269 company documents to capture variations in emergent logics. The network was mapped to include 63 nodes and 366 edges to analyse power structure and mechanisms.FindingsThe socio-economic organising principles of sustainable organisation, their sources of power and their logics are identified. Economic and social logics are revealed, yet the dominance of economic logics creates risks to their coexistence. Logics are largely shaped in pre-competitive activities, and resource fitness to collaborative clusters limits access for non-commercial actors.Research limitations/implicationsPowerful firms use network structures and collaborative and concurrent inter-organisational relationships to define and diffuse their conceptualisation of sustainability and restrict competing logics.Originality/valueThis novel study contributes to sustainable supply chain management (SSCM) through presenting the socio-economic logic as a new conceptual framework to understand the action of sustainable organisation. The identification of sophisticated mechanisms of power and hegemonic control in the network opens new research agendas.

We argue that they did not explicitly discover negation because of their insistence on linguistic parallelism; they did not recognize logical conjunction nor logical disjunction because of juxtaposition or prefixation; they did not identify the notion of sufficient condition; negation of quantifiers was treated as a problem of extension; their notion of proposition was limited; they discovered some intensionality phenomena but did not explore them very deeply; they insisted more on argumentation than on logic. However our exploration of these limitations shows that the Moists had discovered many logical phenomena and that their attention to the structure of the proposition and to their parallelism reveals a real interest in formal methods.

Abstract:

This study presents a novel design approach combining wave pipelining and self reset logic, which provides an elegant solution at high-speed data throughput with significant savings in power and area as compared with other dynamic CMOS logic implementations. To overcome some limitations in SRL art, we employ a new SRL family, namely, dual-rail self reset logic with input disable (DRSRL-ID). These gates depict fairly constant timing parameters, specially the width of the output pulse, for varying fan-out and logic depth, helping accommodate process, supply voltage, and temperature variations (PVT). These properties simplify the implementation of wave pipelined circuits. General timing analysis is provided and compared with previous implementations. Results of circuit implementation are presented together with conclusions and future work.

Abstract:

The evaluation of intervention is becoming increasingly important in occupational therapy practice and management. Programme logic models aim to assist evaluation by linking programme interventions with intended outcomes. These models include a hierarchy of programme inputs, processes, outputs, outcomes and impacts. This article reviews the literature regarding programme logic models and uses a case example, the Spinal Outreach Team, to illustrate the utility and limitations of this approach to evaluation. A figure is included which illustrates part of the programme logic model developed for the team. It is concluded that use of a programme logic process by occupational therapists facilitates the development of comprehensive evaluation plans and relevant performance indicators.

Abstract:

Purpose – The purpose of this paper is to introduce a transformative service logic-based framework designed to help researchers and practitioners better understand resource integration in liminal periods. Design/methodology/approach – Using netnography, we show how consumers across four countries integrate resources, adopting different value creation practices following natural disasters. Findings – The authors’ novel framework extends current conceptualizations of social and economic exchange. Following a natural disaster, a state of ‘liminality’ occurs when the market economy is temporarily displaced by the moral economy, transitioning to a new transformative service logic. Research limitations/implications – Important implications for theory and practice are discussed. Originality/value – This research proposes an organizing framework comparing the market economy logic and moral economy logic with the new transformative service logic.

Full text

Abstract:

Genome-scale stoichiometric modeling methods, in particular Flux Balance Analysis (FBA) and variations thereof, are widely used to investigate cell metabolism and to optimize biotechnological processes. Given (1) a metabolic network, which can be reconstructed from an organism’s genome sequence, and (2) constraints on reaction rates, which may be based on measured nutrient uptake rates, FBA predicts which reactions maximize an objective flux, usually the production of cell components. Although FBA solutions may accurately predict the metabolic behavior of a cell, the actual flux predictions are often hard to interpret. This is especially the case for conditions with many constraints, such as for organisms growing in rich nutrient environments: it remains unclear why a certain solution was optimal. Here, we rationalize FBA solutions by explaining for which properties the optimal combination of metabolic strategies is selected. We provide a graphical formalism in which the selection of solutions can be visualized; we illustrate how this perspective provides a glimpse of the logic that underlies genome-scale modeling by applying our formalism to models of various sizes.

Abstract:

PurposeThe purpose of this study is to examine how multi-tier suppliers respond to the institutional pressures for the implementation of sustainable supply management (SSM) practices in supply chains, and what institutional logics allow them to do so.Design/methodology/approachThis study employs a qualitative research design, drawing on data from semi-structured interviews with 46 owners and managers of multi-tier suppliers and 18 key informants of diverse stakeholders. Following an abductive approach, institutional theory conceptually guides the analytical iteration processes between theory and interview data.FindingsThe findings demonstrate two kinds of thematic responses to institutional pressures – coupling (good side) and decoupling (dark side) of the supply chain – used by the factory management of multi-tier suppliers. This paper also identifies multiple institutional logics – market-led logic, values-led logic and holistic sustainability logic – that are perceived to conflict (trade-offs) and complement (synergies) the SSM implementation.Research limitations/implicationsBy investigating the perspectives of the factory management of upstream apparel suppliers, this study enhances the understanding of the connection between (de)coupling responses and institutional logics inside the multi-tier supplier firms. Further research would be required to include more downstream tiers including the ultimate users.Practical implicationsThe findings may be of particular attention to brand-owning apparel retailers, industry leaders and policymakers who are seeking to understand multi-tier suppliers' challenges, conflicts and (de)coupling responses, and become aware of how they can be dealt with.Originality/valueThis study contributes to and expands the embryonic research stream of sustainable multi-tier supply chain management by connecting it to the wider application of institutional theory.

Abstract:

AbstractWe give some negative results on the expressiveness of naïve set theory (NS) in LP and in the four variants of minimally inconsistent LP defined in Crabbé (2011): ${\rm{L}}{{\rm{P}}_m},{\rm{L}}{{\rm{P}}_ = },{\rm{L}}{{\rm{P}}_ \subseteq }$, and ${\rm{L}}{{\rm{P}}_ \supseteq }$. We show that NS in LP cannot prove the existence of sets that behave like singleton sets, Cartesian pairs, or infinitely ascending linear orders. We show that NS is close to trivial in ${\rm{L}}{{\rm{P}}_m}$ and ${\rm{L}}{{\rm{P}}_ \subseteq }$, in the sense that its only minimally inconsistent model is a one-element model. We show that NS in ${\rm{L}}{{\rm{P}}_ = }$ and ${\rm{L}}{{\rm{P}}_ \supseteq }$ has the same limitations we give for NS in LP.

Abstract:

PurposeThe purpose of this paper is to investigate how sub-suppliers decouple the implementation of sustainable supply management practices in supply chains, and what institutional logics permit these suppliers to do so.Design/methodology/approachFollowing a qualitative design, we conducted 23 in-depth semi-structured interviews with owners and managers of apparel sub-suppliers. To corroborate research findings, the views of owners and managers were triangulated by further interviewing 18 key representatives of wide-ranging institutional actors.FindingsThe findings suggest that owners and managers of sub-suppliers use two decoupling responses: (1) consensual strategy to compromise sustainability requirements (2) concealment strategy. In addition, this paper identifies multiple institutional types of conflicting logics: instrumental logic, legitimacy logic complexity and gaps in normative logic, which interplay amongst sub-suppliers whereby permit to decouple the implementation of supply management practices.Research limitations/implicationsWhile the current paper provides an early contribution from the perspectives of second-tier and third-tier suppliers, future research could be extended to include further upstream sub-suppliers and downstream tiers including the end consumers.Practical implicationsIt is important for brand-owning retailers and first-tier suppliers to predict sub-suppliers' decoupling behaviour and conflicts for supply management practices implementation since they may present potential vulnerability for buyers and lead suppliers.Originality/valueThis study extends the application of institutional theory and contributes to the literature on extended suppliers' supply management practices in a developing country context, which is an under-researched area.

Abstract:

Purpose While much has been debated about venture formation and demise, the behavioral dynamics of why entrepreneurs intend to continue and persevere post-startup have received scant attention and scrutiny. Building upon the rich tapestry of entrepreneurial cognition, the purpose of this paper is to forward entrepreneurial continuance logic as a theoretical framework to empirically investigate the antecedents, contingencies and mediators of entrepreneurial continuance. Design/methodology/approach Using observations from surveying 156 practicing entrepreneurs across the USA, UK, South Africa and India, this research offers interesting findings. Findings Results surface attitudinal tensions between the transactional attitudes of entrepreneurial climate, entrepreneurial responsiveness and calculative commitment and the relational attitudes of affective and normative continuance. Specifically, the authors find that affect is the strongest direct predictor of continuance intentions but only in the absence of entrepreneurial responsiveness behavior. Research limitations/implications Entrepreneurial responsiveness, rather than commitment, is found to be a core continuance constituent, traceable as a positive influence on continuance as a direct antecedent, a moderator and a mediator. Practical implications The research reveals that entrepreneurs willing to seize and adapt to a changing entrepreneurial landscape are more like to continue with their ventures, but not just driven by strict underpinnings of affect and norms but by a strong sense of economic rationality. Social implications Entrepreneurial continuance is an important behavioral phenomenon with substantial socio-economic consequences. Given the scant attention paid to entrepreneurial continuance – symptomatic of broader downstream effects of entrepreneurial survival and positive socio-economic spillovers, the authors embark on a systematic investigation of continuance intention as post-startup behavior. Originality/value The paper explains post-startup entrepreneurial behavior in several ways. First, while affective commitment, a relational attitude, still drives continuance intentions, calculative commitment, a transactional attitude, is a significant contender. Interestingly, the nature of contemporary entrepreneurship disregards continuance behavior based on norms. Second, entrepreneurial responsiveness needs to be cautiously examined in relationship to commitment and continuance. Entrepreneurial responsiveness, a transactional attitude, positively influences continuance; however, in the presence of a relational attitude such as affective commitment, the interplay reduces continuance intentions. Third, perceptions of entrepreneurial climate are found to trigger more opportunity-seeking behavior among entrepreneurs, which in turn increases an entrepreneur’s intention to continue.

Abstract:

The logic blocks of Field Programmable Gate Array (FPGA) basic unit are mainly composed of Look-Up-Tables (LUTs). The traditional LUTs use the static random access memory (SRAM), which causes FPGA reach the limitation in term of the density, speed, and configuration overhead. In this paper, a novel nanometer memristor-based LUT (NMLUT) is composed of memristors, MOS field effect transistors, decoders, resistors. A three-input NMLUT and a four-input NMLUT circuits are investigated. Moreover, an adder is used to verify the practicality of NMLUT circuit. The proposed NMLUT circuit can implement some combinational logic functions through specific configuration and it is better in data transmission and data storage than the traditional LUT. Since NMLUT circuit is compatible with the mainstream circuit in the FPGA, it can effectively solve the limitations of the field FPGA. The correctness of the results is verified in PSPICE software.

Full text

Abstract:

A novel fuzzy control scheme with adaptation algorithms is developed for robot manipulators’ system. At the beginning, one adjustable parameter is introduced in the fuzzy logic system, the robot manipulators system with uncertain nonlinear terms as the master device and a reference model dynamic system as the slave robot system. To overcome the limitations such as online learning computation burden and logic structure in conventional fuzzy logic systems, a parameter should be used in fuzzy logic system, which composes fuzzy logic system with updated parameter laws, and can be formed for a new fashioned adaptation algorithms controller. The error closed-loop dynamical system can be stabilized based on Lyapunov analysis, the number of online learning computation burdens can be reduced greatly, and the different kinds of fuzzy logic systems with fuzzy rules or without any fuzzy rules are also suited. Finally, effectiveness of the proposed approach has been shown in simulation example.

Abstract:

This article addresses contemporary art as a means to investigate how, and to what extent, financial logic impacts upon the socio-cultural sphere. Its contribution is twofold: on the one hand, the article shows that contemporary art’s valuation practices increasingly reflect the logic of capitalization; on the other hand, it assesses the emancipatory potential of blockchain technology for the cultural sphere. In relation to the latter I argue that, in spite of the technological novelty of blockchain-based art projects, these nonetheless fail to challenge a received logic of finance. This exposes the limitations to technological determinism as a means of countering financial power in the socio-cultural sphere, and points to new problems for art’s valuation methods in relation to the liquid logic of algorithmic finance.

Abstract:

Purpose The institutional logic in developing countries is changing from aid toward trade, having implications for institutionally embedded supply chains (SCs) and their members. The purpose of this study is to investigate the transition from aid toward trade through a theoretical lens of institutional logics and the implications of changing logics for SC members and designs. Design/methodology/approach This is a large-scale qualitative study of the SCs of maintenance and repair operations (MRO) of water points. Empirical data were collected via 53 semi-structured interviews, observations, including photographs, and field notes from several echelons of MRO SCs in ten different Ethiopian districts. Findings In spite of the same underlying tenet of a unidirectional trajectory toward a business logic, the study shows that the co-existence or constellation of different institutional logics resulted in diverse practices that impacted SC design. Research limitations/implications The research was carried out in the MRO SC at a time of changing institutional logics, thereby being able to study their transition or constellation of logics. Practical implications The research has implications for policymakers and development practitioners: when designing and implementing rural water supply programs, the presence of co-existing logics and the lack of uniform SC designs should not be viewed as a hindrance. In fact, the study showed how constellations of logics can provide ways through which water points continue functioning and providing clean drinking water to the communities. Originality/value Few studies so far have focused on institutional logics and their implications for SC design.

Abstract:

Pronunciation teaching is an important stage in language learning activities. This article tackles the pronunciation scoring problem where research has demonstrated relatively low human-human and low human-machine agreement rates, which makes teachers skeptical about their relevance. To overcome these limitations, a fuzzy combination of two machines scores is suggested. The experiments were carried in the context of Algerian pupils learning to read Arabic. Although the native language of Algerian pupils is a dialect of Arabic, Modern Standard Arabic remains difficult for them with difficult sounds to master and letters close in their pronunciation. The article presents a fuzzy evaluation system including both oral reading fluency, and intelligibility. The fuzzy system has shown that despite the disparities between human ratings, its scores correspond at least to one of their ratings and most of the time its ratings are in favor of learners. Therefore, fuzzy logic, more favorable than thresholding systems, encourages learners to pursue their training.

Abstract:

Purpose The purpose of this paper is to understand conflicts in sustainability reporting (SR) preparation. Design/methodology/approach In the preparation of SRs, the logic of financial rationality is often assumed to take precedence over the logic of sustainability. Based on an explorative qualitative case study of a large Swedish retailer, the paper problematizes this view. Over a reporting cycle, employees and consultants involved in the preparation process are interviewed. Conflicting ideas about SRs are identified and analyzed through the lens of institutional logics. Findings The study identifies five tensions in SR preparation. These tensions relate to conflicting ideas of what an SR is, how it should be written and how it should be used. Among findings, a conflict of logics can be found as the basis of at least one tension. However, tensions may also emerge within a shared sustainability logic. Research limitations/implications A contribution of the study is that it sets its finger on the actual fieldwork with SRs. The study shows that it is unreasonable to claim that SRs are “self-evidently” captured by management according to financial rationality. Possibly, the nature of the studied firm, a company within the pharmaceutical and health sector, implies a stronger sustainability logic than in other firms. Practical implications According to the study, the results of an SR preparation process are highly dependent on the sometimes conflicting ideas of preparers and others within the company. It is of high importance to identify and clarify such conflicting ideas already in the beginning of the process, to link the SR to the corporate social responsibility strategy of the firm, and to involve top management in the process. Originality/value The study identifies underlying tensions in SR preparation. It also introduces a theoretical framework that makes it possible to analyze tensions in the preparation process.
