Tracking digital footprints: anonymity within the bitcoin system
Authors: Reynolds Perri , Irwin Angela S.M. 
Published: May 2017

Purpose
The purpose of this paper is to critically analyse research surrounding the anonymity of online transactions using Bitcoin and report on the feasibility of law enforcement bodies tracing illicit transactions back to a user’s real-life identity.

Design/methodology/approach
The design of this paper follows on from the approach taken by Reid and Harrigan (2013) in determining whether identifying information may be collated with external sources of data to identify individual users. In addition to conducting a detailed literature review surrounding the anonymity of users, and the potential ability to track transactions through the blockchain, four Bitcoin exchange services are examined to ascertain whether information provided at the sign-up stage is sufficiently verified and reliable. By doing so, this research tests the ability for law enforcement to reasonably rely upon this information when attempting to prosecute individuals. Additionally, by submitting fake information for verification, the plausibility of these services accepting fraudulent or illegitimate information is also tested.

Findings
It may be possible to identify and prosecute bad actors through the analysis of transaction histories by tracing them back to an interaction with a Bitcoin exchange. However, the compliance and implementation of anti-money laundering legislation and customer identification security standards are insufficiently used within some exchange services, resulting in more technologically adept, or well-funded, criminals being able to circumvent identification controls and continue to transact without revealing their identities. The introduction of and compliance with know-your customer and customer due diligence legislation is required before law enforcement bodies may be able to accurately rely on information provided to a Bitcoin exchange. This paper highlights the need for research to be undertaken to examine the ways in which criminals are circumventing identity controls and, consequently, financing their illicit activities.

Originality/value
By ascertaining the types of information submitted by users when exchanging real currency for virtual currency, and seeing whether this information may be accepted despite being fraudulent in nature, this paper elucidates the reliability of information that law enforcement bodies may be able to access when tracing transactions back to an individual actor.
Structural behavior of a pre-stressed cable steel truss exposed to fire
Authors: Xia Yunchun 
Published: May 2017

Purpose
This paper aims to present the results of a study on the behaviour of a pre-stressed cable steel truss exposed to fire under fire conditions, basing on the results of a large programme of experimental tests.

Design/methodology/approach
The research investigated the deformation and stress change on a pre-stressed steel cable, including the deflection and displacements at different joints and fire behaviour of the pre-stressed steel cable. In other words, the structural behaviours at different loaded pre-stress, the vertical loading, steel cable height, truss dimension and the final temperature were compared in case of fire.

Findings
The results showed that the strain of longitudinal chord was far larger than those of the transverse chords, the strains of lower chords were significantly larger than those of the upper chords, strain of the chord near the longitudinal centreline were also larger than those of the outside transverse chords. During heating, the displacement and strain gradually changed from linear to nonlinear with loading, and the yielded chord had also in an order those chords which were at mid-span and near to the longitudinal centreline, yielded at first.

Originality/value
Temperatures in the furnace and at several points of the pre-stressed cable steel truss, as well as deformations, deflections and the stress changes of upper chord and the bottom steel cable and the change of displacement at different joint were measured to achieve those goals and, consequently, to assess the deformation behaviours and temperature of the pre-stressed steel cable.
Dynamic multi-actor engagement in networks: the case of United Breaks Guitars
Authors: Li Loic Pengtao , Juric Biljana , Brodie Roderick J. 
Published: May 2017

PurposeThe purpose of this paper is to explore the dynamic process of multi-actor engagement by examining how it evolves and spreads in actor networks. The authors challenge the dyadic perspective adopted by previous research.Design/methodology/approachAn abductive theorizing approach uses a longitudinal case study to develop a theoretical framework of the iterative process of multi-actor engagement. The authors draw on the contemporary literature on engagement, service-dominant logic and value propositions.FindingsThe research shows that engagement conditions, via actors’ appraisals, lead to engagement properties and result in engagement outcomes as the new conditions for the next iteration. Changes within this multi-actor engagement process lead the network to evolve over time.Research limitations/implicationsThe authors highlight the importance of adopting a dynamic multi-actor perspective of engagement and provide foundations for further research. The use of longitudinal methods that focus on the groups of actors in the evolving network is a key consideration.Practical implicationsThere is the need to understand and measure the dynamic process of engagement among different groups of actors within networks in the service context.Originality/valueThis is the first empirical study to explore the dynamics of engagement among multiple actors in the network. This leads to the expansion of Storbackaet al.’s (2016) conceptual work by identifying the iterative nature of the multi-actor engagement process, and new components in the process (i.e. actors’ connections, value propositions and engagement outcomes), as well as clarifying existing ones (e.g. engagement properties and actors’ appraisals).
Roseda’s growth decision
Authors: Leggio Karyl , Taylor Marilyn 
Published: May 2017

Synopsis
Roseda is a family-operated business that had its beginnings in a farm that Ed and his wife purchased before his retirement in 1994. The company’s current business strategy emphasizes producing high-quality natural Black Angus beef without using hormones, chemical additives or antibiotics in cattle feeding and by dry aging the carcasses for enhanced flavor. This case focuses on the alternative growth strategies that Ed Burchell confronts for Roseda in early 2015.

Research methodology
The founder of Roseda Beef and the lead author became acquainted many years ago. In 2014, the two owners of Roseda agreed to have a case written about the firm. The case is based on formal interviews, on site observations at Roseda Farms, and an extensive review of the documentation that exists on this privately held company. In addition, the company made some internal documents available including the income statements and balance sheets for this private company.

Relevant courses and levels
This course has been taught four times at the MBA level so far: twice in a strategic management course, and twice in a financial strategy course.

Theoretical bases
Roseda Beef was developed to provide students in a capstone strategy or finance course the opportunity to undertake a situational analysis including the firm’s summary financials and the rudimentary financial analysis of the expansion opportunities that are included in the case. The case is based on capital budgeting principles in finance and fundamentals of strategy development.
The March of Dimes: branding in the not-for-profit sector
Authors: Paden Nita , Albritton M. David , Mitchell Jennie , Staples Douglas 
Published: May 2017

Synopsis
This case involves the March of Dimes (MOD) Foundation, the “leading nonprofit organization for pregnancy and baby health.” MOD’s mission was to support medical research, organize volunteer workers, and provide community services and education to save babies’ lives (www.marchofdimes.org). The strategic issue in the case involves creating awareness of both the mission and services of MOD and the critical issue driving that mission – premature births. The organization must create a desire for various target markets to take action in response to the problem. The main protagonist is Doug Staples, Senior Vice President for Marketing and Communications.

Research methodology
Data were collected via personal interviews with the primary protagonists, Doug Staples, and Mike Swenson of the Barkley agency. The MOD provided quantitative Gallup studies they commissioned, as well as documents unveiling the roll-out in the San Jose, CA region. The Barkley Agency provided qualitative data from a study which consisted of eight focus groups conducted in two markets and ten personal interviews. Secondary research was used to provide a support for industry and market data, to supplement organizational facts provided by the MOD, and to identify and link marketing theory to the situations provided in the case. The organization, facts and characters in this case were not disguised. MOD was consulted throughout the case development process.

Relevant courses and levels
This case study is recommended for marketing courses at the undergraduate level. It is most appropriate for marketing management, introductory marketing, or marketing strategy classes. Additionally, this case is a good fit for courses focused upon not-for-profit marketing issues.

Theoretical bases
The strongest opportunities to apply theory using this case relate to branding (see De Chernatony and Dall’Olmo Riley, 1998 for a content analysis of the brand literature). These theories include brand image and personality (Aaker, 1997; Belk, 1998; Grohmann, 2009), brand awareness (Aaker, 2002), brand involvement and customer loyalty (Brakus et al., 2009), brand engagement (Sprott et al., 2009), brand relationships (Breivik and Thorbjornsen, 2008), and brand equity (Aaker, 2002, 2008). Specifically, question 2 addresses brand personality, and questions 3 and 4 explore relationships with the brand such as the emotional power of the brand and brand association. Question 6 focuses on positioning strategy.
A Portrait of Failure: Ongoing Funding Cuts to Australia's Cultural Institutions
Authors: van Barneveld Kristin , Chiu Osmond 
Published: May 2017

AbstractThree decades of government budget cuts have placed significant financial pressure on Australia's cultural institutions. Institutions are increasingly trying to attract non‐government funding to fulfil their legislative mandates to collect, maintain, and exhibit Australian and international art, to educate and inform the public, and preserve Australia's political, social, and cultural history. Evidence suggests that, despite these efforts, sources of funding have not changed significantly. Budget cuts are impacting a range of areas including acquisitions, preservation, digitisation, as well as limiting access to researchers and the public. This paper concludes that a public review of the roles played by cultural institutions is required, including consideration of the level of public funding provided. To do otherwise is to ignore the importance of Australia's cultural heritage.
The Interplay Between Employee and Firm Customer Orientation: Substitution Effect and the Contingency Role of Performance‐Related Rewards
Authors: Herhausen Dennis , De Luca Luigi M. , Weibel Michael 
Published: May 2017

AbstractThis paper identifies and explains a potential tension between a firm's emphasis on customer orientation (CO) and the extent to which employees value CO as a success factor for individual performance. Based on self‐determination theory and CO implementation research, the authors propose that firm CO may represent both autonomous and controlled motivations for CO, but that employees’ CO is more strongly linked to individual performance when employees experience solely autonomous motivation. Hence, the authors expect a substitution effect whereby the link between employees’ CO and their performance is weaker when firm CO is high. Furthermore, the authors examine a boundary condition for the previous hypothesis and propose that performance‐contingent rewards have a positive effect on the internalization of the extrinsic motivation stemming from firm CO. Two multilevel studies with 979 employees and 201 top management team members from 132 firms support these hypotheses. Against previous research, these findings offer a new perspective on the effectiveness of CO initiatives, propose employees’ motivational states as the theoretical explanation for the heterogeneity in the link between employee CO and performance, and reappraise the role of performance‐contingent rewards in CO research. Managerial implications for the effective implementation of customer‐oriented initiatives within firms are provided.

Published: May 2017

AbstractFortification of queso blanco (QB) with flaxseed oil (FO) containing omega‐3 polyunsaturated fatty acids may provide a functional food with health benefits such as improved cell, brain, and retina functionality, and protection against cardiovascular and immune‐inflammatory diseases. However, QB experiences a short shelf life because of the early development of yeasts and molds and addition of FO may increase susceptibility to lipid oxidation. Oregano essential oil (OEO) is known for its antimicrobial and antioxidant properties, but due to its intense flavor compounds it may not be suitable for direct incorporation into QB. Thus, incorporation of OEO into an edible film prepared with whey protein isolate (WPI) may improve the shelf life of QB. Scanning electron microscopy (SEM) micrographs revealed that FO was successfully retained by the cheese after homogenization. The thiobarbituric‐acid‐reactive‐substances (TBARS) and yeast and mold counts (YMC) of the wrapped cheeses were analyzed during 60 d of refrigerated storage. The oxidation rate increased significantly for nonwrapped QB containing FO (QBFO) during storage, however wrapping with WPI edible films containing OEO (WOF) significantly limited lipid oxidation and prevented growth of yeasts and molds. This study demonstrated the antioxidant and antimicrobial properties of WOF for preservation of QBFO during refrigerated storage.

Published: May 2017

BackgroundThe aim of this study was to assess the incidence and contributing factors of hypophosphatemia and the association with poor long‐term outcome after nontraumatic intracranial hemorrhage.MethodsThis was a prospective, observational study of patients with nontraumatic intracranial hemorrhage (i.e., aneurysmal or perimesencephalic subarachnoid hemorrhage, or spontaneous intracerebral or intraventricular hemorrhage) treated in the intensive care unit (ICU) at our university hospital. Plasma phosphate concentrations were measured serially in 2‐day sections during the 6 day study period. The ICU mortality was recorded, 3‐month and 1‐year outcomes were assessed using the Glasgow Outcome Scale.ResultsOne hundred patients were enrolled. The frequency of hypophosphatemia (Pi ≤ 0.65 mmol/l) was 70%. Chronic hypertension, acute hydrocephalus, and diffuse brain edema were more common in patients with hypophosphatemia compared with normophosphatemics (44% vs. 21%, P = 0.021; 59% vs. 33%, P = 0.021; and 43% vs. 13%, P = 0.004, respectively). Hypophosphatemic patients had higher maximum SOFA scores [10 (7–11) vs. 7.5 (5.75–10), P = 0.024]. Initial phosphate concentration correlated inversely with APACHE II score on admission (ρ = −0.304, P = 0.002) and SOFA score on the first ICU day (ρ = −0.269, P = 0.008). There was no difference in outcome between hypophosphatemic and normophosphatemic patients. In all five patients with severe hypophosphatemia (Pi < 0.32 mmol/l) the functional outcome was good.ConclusionHypophosphatemia was common in this patient population. The outcome was similar between hypophosphatemic and normophosphatemic patients. Chronic hypertension, acute hydrocephalus, diffuse brain edema and higher SOFA scores were more common in patients with hypophosphatemia.

ProblemInvestigating the stress response in the central cotyledon zone of placental tissue in pregnancies with PPROM, PTB, and at term in labor.Method of studyGene expression of Hsp27, Hsp60, Hsp70, Hsp90, and HspBP1 was compared between these particular groups. Correlation between variables including Hsp gene expression in placental tissue and the gestational age at delivery, WBC count at admission, and serum levels of CRP at admission in patients with PPROM and PTB was determined.ResultsBoth PPROM and PTB pregnancies were associated with altered Hsp gene expression profile. While PPROM and PTB always induced upregulation of Hsp27 and Hsp60, downregulation of Hsp70 and HspBP1 was present entirely in patients with PPROM. HspBP1 expression profile was also able to differentiate between PPROM and PTB pregnancies. The highest mRNA levels of Hsp60 and Hsp70 were detected in PTB pregnancies with elevated CRP levels at admission. Some of the examined Hsp displayed increased expression with advancing gestational age in both groups (PPROM: Hsp27, Hsp70, and Hsp90; and PTB: Hsp27).ConclusionUpregulation of Hsp27 is a common phenomenon shared between pregnancies affected with PTB and PPROM. On the other hand, downregulation of Hsp70 and HspBP1 represents a unique feature of PPROM.

Published: May 2017

BackgroundPredictors and implications of early left ventricular ejection fraction (LVEF) improvement with guideline‐directed medical therapy (GDMT) in new‐onset idiopathic nonischemic cardiomyopathy (NICM) with narrow QRS complex are not well described. The objectives were to describe predictors of LVEF improvement after 3 months on GDMT and adverse cardiac events based on post‐GDMT LVEF status (≤35% vs. >35%).MethodsA retrospective cohort study was performed in subjects with new‐onset NICM, LVEF ≤35%, and narrow QRS complex. Associations for baseline variables with post‐GDMT LVEF improvement and absolute change in LVEF (∆LVEFGDMT) were assessed. Cox proportional hazards models assessed associations for post‐GDMT LVEF status with adverse cardiac events.ResultsIn 70 subjects, 31 (44%) had post‐GDMT LVEF ≤35% after a median follow‐up time of 97.5 days (interquartile range, 84–121 days). In final multivariable models, severely dilated left ventricular end‐diastolic diameter (LVEDD), compared with normal LVEDD, strongly predicted post‐GDMT LVEF ≤35% (odds ratio, 7.77; 95% confidence interval [CI], 1.39–43.49; p = .02) and ∆LVEFGDMT (β = −15.709; standard error = 4.622; p = .001). Subjects with post‐GDMT LVEF ≤35% were more likely to have adverse cardiac events over a median follow‐up time of 970.5 days (unadjusted hazard ratio, 2.15; 95% CI, 0.93–4.96; p = .07). In the post‐GDMT LVEF ≤35% group, 9 of 26 subjects (35%) had long‐term LVEF > 35%.ConclusionIn new‐onset NICM with narrow QRS complex, nondilated LVEDD predicted early LVEF improvement. Those with post‐GDMT LVEF ≤35% had higher risk of adverse cardiac events, but a substantial proportion demonstrated continued long‐term LVEF improvement.
Systematic review with meta‐analysis: the efficacy of vonoprazan‐based triple therapy on Helicobacter pylori eradication
Authors: Jung Y. S. , Kim E. H. , Park C. H. 
Published: May 2017

AbstractBackgroundIn order to increase eradication rates, vonoprazan, a novel potassium‐competitive acid blocker, has been used in Helicobacter pylori eradication therapy.AimTo summarise the results of the efficacy of vonoprazan‐based triple therapy, helping clinicians to better understand the benefit of vonoprazan in the treatment of H. pylori infection.MethodsWe conducted a systematic literature search on MEDLINE, EMBASE, and the Cochrane Library using the primary keywords “vonoprazan,” “takecab”, “TAK‐438,” “potassium,” “competitive,” “potassium‐competitive,” “Helicobacter,” and “pylori.” Studies were included if they evaluated the eradication rate between the vonoprazan‐based and proton pump inhibitor (PPI)‐based triple therapies.ResultsTen studies and 10 644 patients were evaluated. The crude H. pylori eradication rate determined by intention‐to‐treat analysis was 87.9% and 72.8% in the vonoprazan‐based triple therapy and PPI‐based triple therapy respectively. The eradication rate of the vonoprazan‐based triple therapy was superior to that of the PPI‐based triple therapy (pooled risk ratio [RR] [95% confidence interval (CI)]=1.19 [1.15‐1.24]) In addition, there was no significant difference in dropout rate due to adverse event between the regimens (pooled RR of the vonoprazan‐based triple therapy [95% CI]=0.69 [0.23‐2.03]). The incidence of any adverse events also did not differ between the regimens (pooled RR [95% CI]=1.02 [0.78‐1.34]).ConclusionsThe vonoprazan‐based triple therapy showed superior efficacy in terms of H. pylori eradication as compared to the PPI‐based triple therapy. In addition, the vonoprazan‐based triple therapy showed comparable tolerability and incidence of adverse events.
Preference of an insular flying fox for seed figs enhances seed dispersal of a dioecious species

Published: May 2017

AbstractInteractions among multiple species form complex networks of interdependences and are considered primary factors in the generation and maintenance of biodiversity. Pteropodid bats are keystone species that provide important ecosystem services of pollination and seed dispersal in the tropics and subtropics. In this study, we investigated the utilization and preference of food resources by the insular frugivorous flying fox Pteropus dasymallus. We found that fig species constituted the major portion of the diet of the flying fox (94.6%). When foraging, the flying fox preferred seed figs from female trees over gall figs from male trees in functionally dioecious fig species. Germination experiments showed a significantly higher percentage of germination for fig seeds in feces than those from pellets and ripe figs (feces: 80.2%, pellets: 23.4%, ripe figs: 32.9%). Considering the active selection of seed figs and avoidance of gall figs by foraging flying foxes, we suggest that the abundance of seed figs accurately represents food availability for dioecy. This preference for seed figs or viable seeds can effectively promote the survival of pollinating wasps and might reinforce the evolution of dioecism in figs. In addition, the effects of gut passage on seed germination, in combination with the capacity of flying foxes to travel long distances, may substantially contribute to the efficiency of flying foxes as seed dispersers.
