How do Open Source software companies respond to institutional pressures? A business model perspective
Authors: Mouakhar Khaireddine , Tellier Albéric 
Published: May 2017

PurposeOpen Source software companies (OSSCs) are confronted with institutional pressures from Open Source software (OSS) communities. They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data.Design/methodology/approachThe methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample.FindingsThe quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning.Research limitations/implicationsThe results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning.Practical implicationsThis study allows the authors to highlight two main practical contributions for OSSCs’ directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables.Originality/valueThis paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more “fine-grained” analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).
Missing cloud security awareness: investigating risk exposure in shadow IT
Authors: Walterbusch Marc , Fietz Adrian , Teuteberg Frank 
Published: May 2017

Purpose
On account of its easy and intuitive usage as well as obvious advantages (e.g. access to work data from anywhere, at any time and through any means) the evolutionary cloud computing paradigm favors the use of shadow IT. Since many employees are not aware of the associated risks and possible legal violations, unauthorized use of cloud computing services could result in substantial risk exposure for any company. The purpose of this paper is to explore and to extend the body of knowledge concerning the topic of cloud computing with regard to shadow IT.

Design/methodology/approach
The aim of this contribution is to identify the reasons for the use of cloud computing services and the resulting shadow IT from an employee’s perspective, to demonstrate the counteractions a company may take against the unauthorized use of cloud computing services and to elaborate on the inherent opportunities and risks. We follow a mixed-methods approach consisting of a systematic literature review, a cloud computing awareness study, a vignette study and expert interviews.

Findings
Based on a triangulation of the data sets, the paper at hand proposes a morphological box as well as a two-piece belief-action-outcome model, both from an employee’s and employer’s point of view. Our findings ultimately lead to recommendations for action for employers to counteract the risk exposure. Furthermore, also employees are sensitized by means of insights into the topic of unauthorized usage of cloud computing services in everyday working life.

Research limitations/implications
The limitations of the triangulation reflect the limitations of each applied research method. These limitations justify why a mixed-methods approach is favored – rather than relying on a single source of data – because data from various sources can be triangulated.

Practical implications
The paper includes recommendations for action for the handling of the unauthorized usage of cloud computing services within a company, e.g., the set up of a company-wide cloud security strategy and the conduction of an anonymous employee survey to identify the status quo.

Originality/value
This paper fulfills an identified need to explore the usage of cloud computing services within the context of shadow IT.
From owning to sharing: understanding the emergence of social sharing services
Authors: Kim Heetae , Choi Kyu Ha , Kim Ki Joon , Park Eunil 
Published: May 2017

Purpose
The purpose of this paper is to identify the motivational factors that help shape user perceptions of and attitudes toward car-sharing services and develop a research model that integrates these factors with the technology acceptance model to explicate car sharing’s adoption pattern.

Design/methodology/approach
An online survey was administered to examine the role of proposed motivational factors for the adoption of wearable healthcare devices. Confirmatory factor analysis and structural equation modeling were conducted on collected data (n=638) to demonstrate the reliability and validity of the measurement and structural model.

Findings
Perceived reliability, compatibility, and enjoyment of car-sharing services as well as users’ innovative tendencies are positively associated with usage intention. However, users’ privacy concern and perceived cost of using the services are found to have no significant effects on the adoption of the services.

Originality/value
While the recent advent of mobile communication devices and services has increased access to social sharing-based platform services such as car sharing, this study provides a research framework that helps to understand how various psychological factors contribute to the adoption of a social-sharing service.
The CENDARI infrastructure in GIS-based historical research
Authors: Moscicka Albina Kinga 
Published: May 2017

Purpose
The purpose of this paper is to propose a way of using already existing archival resources in the geographic information system (GIS).

Design/methodology/approach
The essence of the methodology used was to identify semantic relations of archival documents with geographical space and develop their metadata into spatially related metadata, ready to use in GIS and to join geographical names occurring in these metadata with exact places to which they were related to. Research was based on two digital collections from the Library of Contemporary History in Stuttgart on-line service. These collections were related to the First World War and they included metadata prepared in MAB standard.

Findings
As the results of the research, two sample metadata sets related to posters and ration coupons were developed. Thesauruses of coordinates of places and regions mentioned in documents metadata in different semantic context were also created. To complete the methodology, the assumptions of the GIS structure and concept of applying metadata in them, have been proposed.

Research limitations/implications
The research also presents limitations in effective implementation of the proposed solutions, which lie mainly in lack of rules and consequences in recording geographical names in metadata.

Originality/value
The value of the proposed solution is easy way of using already existing data in GIS and possibilities of gathering, managing, presenting and analyzing archives with one parameter more than in traditional databases – with spatial information. The added value and an effective use of already collected data lies in the strong recommendation of defining and implementation of rules for recording geographical names in archival documents metadata. This will help in a wide use of collected data in any spatial-based solutions as well as in automation of process of joining archives with geographical space, and finally in dissemination of collected resources.
Social media-based sponsorship activation – a typology of content
Authors: Gillooly Leah , Anagnostopoulos Christos , Chadwick Simon 
Published: May 2017

Purpose
The purpose of this paper is to thematically categorise sports sponsorship-linked Twitter content and, by drawing on uses & gratifications theory, to map the extent to which these categories cohere with known user motivations for consuming social media.

Design/methodology/approach
Qualitative content analysis of a sample of 1,502 tweets by London 2012 Olympic and Paralympic Games sponsors posted between January 2011 and September 2012 was used to develop the typology of sponsorship-linked Twitter content.

Findings
From the data, a typology is developed, comprising 17 categories grouped under four main types: informing, entertaining, rewarding and interacting. The majority of sponsor tweets (68 per cent) fell into the informing type, with 17 per cent categorised as interacting. While few (2 per cent) tweets were categorised as entertaining, the link to the sponsored event implies a degree of entertaining content even in ostensibly informative, rewarding or interactional sponsorship-linked tweets. Therefore, the typology categories highlight Twitter content produced by sponsors which engages customers, fostering dialogue alongside providing informative and entertaining content.

Practical implications
The typology can inform practitioners’ future sports sponsorship activation planning decisions and can also aid rights holders in tailoring appropriate sponsorship opportunities to potential sponsors, based on an appreciation of the nature of content sought by brand followers.

Originality/value
The typology extends existing understanding of the use of social media within sponsorship activation campaigns by thematically categorising content and mapping this against known user motivations for consuming brand-related social media content.

ObjectiveTo examine whether Massachusetts (MA) health reform affected substance (alcohol or drug) use disorder (SUD)–related hospitalizations in acute care hospitals.Data/Study Setting2004–2010 MA inpatient discharge data.DesignDifference‐in‐differences analysis to identify pre‐ to postreform changes in age‐ and sex‐standardized population‐based rates of SUD‐related medical and surgical hospitalizations, adjusting for secular trends.Data Extraction MethodsWe identified 373,751 discharges where a SUD‐related diagnosis was a primary or secondary discharge diagnosis.FindingsAdjusted for age and sex, the rates of drug use–related and alcohol use–related hospitalizations prereform were 7.21 and 8.87 (per 1,000 population), respectively, in high‐uninsurance counties, and 8.58 and 9.63, respectively, in low‐uninsurance counties. Both SUD‐related rates increased after health reform in high‐ and low‐uninsurance counties. Adjusting for secular trends in the high‐ and low‐uninsurance counties, health reform was associated with no change in drug‐ or alcohol‐related hospitalizations.ConclusionsMassachusetts health reform was not associated with any changes in substance use disorder–related hospitalizations. Further research is needed to determine how to reduce substance use disorder–related hospitalizations, beyond expanding insurance coverage.

Published: May 2017

AbstractObjectivesTo study the predictors of complementary and alternative medicine (CAM) use in patients with early inflammatory arthritis (EIA), and its impact on delay to initiation of disease‐modifying anti‐rheumatic drugs (DMARD).MethodsData were collected prospectively from EIA patients aged ≥ 21 years. Current or prior CAM use was ascertained by face‐to‐face interview. Predictors of CAM use and its effect on time to DMARD initiation were determined by multivariate logistic regression and Cox proportional hazards, respectively.ResultsOne hundred and eighty patients (70.6% female, 58.3% Chinese), of median (interquartile range [IQR]) age 51.1 (40.9–59.8) years and symptom duration 16.6 (9.2–26.6) weeks were included: 83.9% had rheumatoid arthritis, 57% were seropositive. Median (IQR) Disease Activity Score in 28‐joints (DAS28) was 4.3 (2.8–5.7), modified Health Assessment Questionnaire (mHAQ) was 0.38 (0.0–0.88) and 41.3% were CAM users. Chinese race (odds ratio [OR] 5.76 [95%CI 2.53–13.1]), being non‐English speaking (OR 2.68 [95% CI 1.18–6.09]), smoking (OR 3.35 [95% CI 1.23–9.15] and high DAS28 (OR 2.73 [95% CI 1.05–7.09] were independent predictors of CAM use. CAM users initiated DMARD later (median [IQR] 21.5 [13.1–30.4] vs. 15.6 [9.4–22.7] weeks in non‐users, P = 0.005). CAM use and higher DAS28 were associated with a longer delay to DMARD initiation (hazard ratio [HR] 0.69, 95% CI 0.50–0.95 and 0.63, 95% CI 0.43–0.91, respectively) while higher mHAQ was associated with a shorter delay (HR 1.59, 95% CI 1.08–2.34) and race, education level, being non‐English speaking, smoking and seropositivity were not associated.ConclusionsHealthcare professionals should be aware of the unique challenges in treating patients with EIA in Asia. Healthcare beliefs regarding CAM may need to be addressed to reduce treatment delay.

Published: May 2017

AbstractEcological network approaches may contribute to conservation practices by quantifying within‐community importance of species. In mutualistic plant‐pollinator systems, such networks reflect potential pollination of the plants and a considerable portion of the energy consumption by the pollinators, two key components for each party. Here, we used two different sampling approaches to describe mutualistic plant‐hummingbird networks from a cloud forest in the Colombian Western Andes, home to the Colorful PufflegEriocnemis mirabilis, an endemic and critically endangered hummingbird. We contrast networks between two localities (a protected area inside a National park vs. its buffer zone) and across sampling methods (floral visitation vs. pollen loads) to assess how the network structure and the importance of each hummingbird species within the networks may change. Visitation networks were characterized as having higher sampling completeness, yet pollen load network recorded more pollen types than plant species recorded by visitation. Irrespective of the sampling methods, the Colorful Puffleg was one of the most important hummingbird species in the network within the protected area inside the National park, but not in the buffer zone. Moreover, most species‐level network indices were related to hummingbirds’ abundance. This suggests that conservation initiatives aimed at the endangered Colorful Puffleg may both help on the survival of this endangered hummingbird, as well as on maintaining its key role in the mutualistic interaction network inside the National Park. Our study illustrates how conservation practitioners could assess the local importance of endangered species using interaction network approaches.

Published: May 2017

This study examined the value of using a group‐centered approach to evaluate process quality of early childhood education and care (ECEC). Is observed support of group processes a different aspect of classroom quality, and does it predict children's collaborative play in ECEC in the Netherlands? In two play situations, 37 teachers and 120 two‐ to four‐year‐old children were observed with the Classroom Assessment Scoring System (CLASS) Toddler and two new measures. In a two‐level structural equation model, teachers’ support of group processes was positively related to the CLASS domains and to children's collaborative play, over and above the effect of children's cognitive ability and social competence. These findings suggest that ECEC quality evaluation could be enriched by adding group‐centered indicators of classroom quality.
Dealing with Big Numbers: Representation and Understanding of Magnitudes Outside of Human Experience
Authors: Resnick Ilyse , Newcombe Nora S. , Shipley Thomas F. 
Published: May 2017

AbstractBeing able to estimate quantity is important in everyday life and for success in the STEM disciplines. However, people have difficulty reasoning about magnitudes outside of human perception (e.g., nanoseconds, geologic time). This study examines patterns of estimation errors across temporal and spatial magnitudes at large scales. We evaluated the effectiveness of hierarchical alignment in improving estimations, and transfer across dimensions. The activity was successful in increasing accuracy for temporal and spatial magnitudes, and learning transferred to the estimation of numeric magnitudes associated with events and objects. However, there were also a number of informative differences in performance on temporal, spatial, and numeric magnitude measures, suggesting that participants possess different categorical information for these scales. Educational implications are discussed.
Glucose‐6‐phosphate dehydrogenase deficiency induced haemolysis in a woman with newly diagnosed diabetes after normalisation of hyperglycaemia
Authors: ALjishi F. , ALDarwish M. 
Published: May 2017

AbstractBackgroundThe association between diabetes and G6PD deficiency is still a matter of debate. Hemolysis due to G6PD deficiency in people with diabetes has been reported, but is uncommon. To date, twenty‐three cases have been reported from 12 different countries.Case reportWe reported a 19‐year‐old Saudi women newly diagnosed with Type 1 diabetes in whom hemolytic crises occurred soon after normalization of hyperglycemia and revealed a G6PD deficiency. We reviewed the pertinent literature of this phenomenon and discussed the relevant theories.ConclusionWe conclude that in order to reduce the risk of hemolysis, in an area with high incidence of G6PD deficiency, screening of the enzyme activity should be considered in newly diagnosed people with diabetes. In case of G6PD deficiency, it is advisable to correct plasma glucose level gradually in order to avoid the rapid decline in glucose availability.

BackgroundThe objective of this study is to test the conflicting theories concerning the association of negative self and other schemata and paranoid ideation.MethodsA risk‐based approach, including risk stratification, is used to gain insight into the association of the negative self and other schemata that may be shared by individuals or differentiate between individuals at clinical high risk (CHR) for a first‐episode psychosis and those with full‐blown psychosis. The dataset includes a sample of individuals at CHR (n = 137) and a sample of individuals with persisting positive symptoms (PPS, n = 211). The CHR sample was subdivided according to a prognostic index yielding 4 CHR sub‐classes with increasing risk for transition to psychosis.ResultsNegative beliefs about the self were associated with paranoid ideation in CHR and a lower risk state. In the highest risk state and full‐blown psychosis, there is an association with negative beliefs about others.ConclusionThese findings are in line with theories suggesting a switch from a predominantly activated negative self‐schema to a malevolent others‐schema in association with paranoid ideation along the risk‐continuum. However, due to methodological limitations these results should be replicated by future studies.
