Reporting in Agile Portfolio Management: Routines, Metrics and Artefacts to Maintain an Effective Oversight
Authors: Stettina Christoph Johann , Schoemaker Lennard 
Published: May 2018

AbstractIn a world where the speed of change is faster than ever, a growing number of organisations adopts Agile Portfolio Management (APM) to connect their agile teams to business strategy. A domain which has been little explored in literature and professional frameworks. Based on 14 interviews conducted in 10 large European organisations, in this paper we report the preliminary results of our study on reporting routines, artefacts and metrics in Agile Portfolio Management. In our findings we discuss the three generic domains of reporting responsibility and the novel types of reporting routines found in practice. Further, we use the concept of boundary objects to recommend which types of artefacts are effective for which reporting routines.
Teamwork Quality and Team Performance: Exploring Differences Between Small and Large Agile Projects

Published: May 2018

Abstract
Agile principles were originally developed for small projects but are now widely used in larger projects with hundreds of developers. Teamwork quality is essential in any development work, but how does teamwork quality differ in small and large agile projects? We report from an explorative survey with 64 agile teams and 320 team members and team leaders, from 31 teams in small projects and 33 teams in large projects. For small projects, teamwork quality was considered by both team members and team leaders to primarily affect product quality. For large projects, the effect of teamwork quality on product quality was positive when it was rated by team members but was negative when rated by team leaders. At a finer granularity, the six dimensions of teamwork quality that we investigated affected team performance differently in small and large projects. These findings question to what extent findings from previous studies on teamwork in agile development in small projects apply to large projects.

Published: May 2018

AbstractAn Initial Coin Offering (ICO) is an innovative way to raise funds and launch a startup. It is also an opportunity to take part in a project, or in a DAO (Decentralized Autonomous Organization). The use of ICO is a global phenomenon that involves many nations and several business categories: ICOs collected over 5.2 billion dollars only in 2017. The success of an ICO is based on the credibility and innovativeness of project proposals. This fund-raising tool contains however some critical issues, such as the use of tokens that have no intrinsic value and do not generate direct liquidity, and the role of investors in the management of the startup. We analyzed if the Lean Startup methodology is helpful to face this critical aspects and we examined some ICOs in which the proposing team states explicitly that a lean startup approach is used.
Myths and Facts About Static Application Security Testing Tools: An Action Research at Telenor Digital

Published: May 2018

AbstractIt is claimed that integrating agile and security in practice is challenging. There is the notion that security is a heavy process, requires expertise, and consumes developers’ time. These contrast with the agile vision. Regardless of these challenges, it is important for organizations to address security within their agile processes since critical assets must be protected against attacks. One way is to integrate tools that could help to identify security weaknesses during implementation and suggest methods to refactor them. We used quantitative and qualitative approaches to investigate the efficiency of the tools and what they mean to the actual users (i.e. developers) at Telenor Digital. Our findings, although not surprising, show that several barriers exist both in terms of tool’s performance and developers’ perceptions. We suggest practical ways for improvement.
Interface Problems of Agile in a Non-agile Environment
Authors: Theobald Sven , Diebold Philipp 
Published: May 2018

AbstractAgile is the widespread software development approach. But many projects are still working with traditional methods. In addition, non-technical business units continue working in traditional ways. Thus, problems arise on the interface of agile and traditional due to their fundamental differences. To prevent potential problems, one must be aware of the existing interfaces and common pitfalls. Based on a literature search and workshops, we identified existing interfaces, collected and grouped problems. We present the identified problems and propose a matrix that facilitates classification of interface problems. This matrix can be used to identify and classify more problems as well as understanding and preventing problems on the interface of agile and traditional.
Xiphoidectomy for Intractable Xiphodynia

Published: May 2018

AbstractBackgroundXiphodynia is a rare condition with hardly any data published regarding xiphoidectomy as a valid treatment option for intractable disease. It is necessary to bear this syndrome in mind after having filtered out other differential diagnoses.MethodsBetween 2003 and 2015, 11 patients underwent xiphoidectomy for intractable xiphodynia at our institution. Patients’ charts were reviewed including preoperative workup, operative technique, and results. Every patient had routine follow‐ups, 4 weeks after the procedure and 1 year after surgery.ResultsThe main symptom was chest pain in the area of the xiphoid. Conservative treatment trials with different combinations of analgesics over at least 1 year did not lead to insufficient and long‐term improvement, which is why the decision for a surgical xiphoidectomy was eventually made. No postoperative complications occurred. Significant pain relief was achieved in eight out of ten patients; one patient was lost to long‐term follow‐up. Both patients with insufficient pain relief have had previous surgery in form of a sternotomy and upper median laparotomy.ConclusionsXiphodynia is a diagnostic conundrum, which is why reports on its treatment including surgical resection of the xiphoid are even sparser. So far, this is the largest reported series of surgically treated xiphodynia. Correct diagnosis remains the key factor for success. While tenderness over the tip of the xiphoid process combined with protrusion of the xiphoid with a xiphisternal angle of <160° are good indications for surgery, patients after previous operations affecting the xiphoid process are less likely to benefit from xiphoidectomy.
Virtual memory palaces: immersion aids recall
Authors: Krokos Eric , Plaisant Catherine , Varshney Amitabh 
Published: May 2018

Abstract
Virtual reality displays, such as head-mounted displays (HMD), afford us a superior spatial awareness by leveraging our vestibular and proprioceptive senses, as compared to traditional desktop displays. Since classical times, people have used memory palaces as a spatial mnemonic to help remember information by organizing it spatially and associating it with salient features in that environment. In this paper, we explore whether using virtual memory palaces in a head-mounted display with head-tracking (HMD condition) would allow a user to better recall information than when using a traditional desktop display with a mouse-based interaction (desktop condition). We found that virtual memory palaces in HMD condition provide a superior memory recall ability compared to the desktop condition. We believe this is a first step in using virtual environments for creating more memorable experiences that enhance productivity through better recall of large amounts of information organized using the idea of virtual memory palaces.

AbstractAn environmental scan (ES) is an efficient mixed‐methods approach to collect and interpret relevant data for strategic planning and project design. To date, the ES has not been used nor evaluated in the clinical cancer genetics setting. We created and implemented an ES to inform the design of a quality improvement (QI) project to increase the rates of adherence to national guidelines for cancer genetic counseling and genetic testing at three unique oncology care settings (OCS). The ES collected qualitative and quantitative data from reviews of internal processes, past QI efforts, the literature, and each OCS. The ES used a data collection form and semi‐structured interviews to aid in data collection. The ES was completed within 6 months, and sufficient data were captured to identify opportunities and threats to the QI project's success, as well as potential barriers to, and facilitators of guideline‐based cancer genetics services at each OCS. Previously unreported barriers were identified, including inefficient genetic counseling appointment scheduling processes and the inability to track referrals, genetics appointments, and genetic test results within electronic medical record systems. The ES was a valuable process for QI project planning at three OCS and may be used to evaluate genetics services in other settings.
Apraxia profiles—A single cognitive marker to discriminate all variants of frontotemporal lobar degeneration and Alzheimer's disease

Published: May 2018

AbstractIntroductionApraxia is common in neurodegenerative dementias but underrepresented in clinical workup for differential diagnoses.MethodsPraxis‐profiles were assessed with the Dementia Apraxia Test in 93 patients with early stages of biologically supported Alzheimer's disease or frontotemporal lobar degeneration: semantic primary‐progressive aphasia, nonfluent primary‐progressive aphasia, and behavioral variant frontotemporal dementia. Associations with core cognitive deficits of the dementia subtypes (i.e., visuospatial, sociocognitive, and semantic‐linguistic) were explored.ResultsPatients showed significant apraxia compared with healthy controls but also disease‐specific praxis‐profiles. Using only the Dementia Apraxia Test, all four dementia subtypes could be correctly discriminated in 64.4% of cases, and in 78.2% when only distinguishing Alzheimer's disease versus frontotemporal lobar degeneration. Praxis‐profiles showed consistent associations with core cognitive impairments of the different dementia subtypes.DiscussionThe Dementia Apraxia Test is a valid, time‐efficient and versatile cognitive marker to delineate variants of frontotemporal lobar degeneration and Alzheimer's disease in clinical routine, facilitating differential diagnoses of dementia subtypes in early disease stages.
Violent Origins of Authoritarian Variation: Rebellion Type and Regime Type in Cold War Southeast Asia
Authors: Slater Dan 
Published: May 2018

AbstractDictatorships are every bit as institutionally diverse as democracies, but where does this variation come from? This article argues that different types of internal rebellion influence the emergence of different types of authoritarian regimes. The critical question is whether rebel forces primarily seek to seize state power or to escape it. Regional rebellions seeking toescapethe state raise the probability of a military-dominated authoritarian regime, since they are especially likely to unify the military while heightening friction between civilian and military elites. Leftist rebellions seeking toseizethe state are more likely to give rise to civilian-dominated dictatorships by inspiring ‘joint projects’ in which military elites willingly support party-led authoritarian rule. Historical case studies of Burma, Indonesia, Malaysia and Vietnam illustrate the theory, elaborating how different types of violent conflict helped produce different types of dictatorships across the breadth of mainland and island Southeast Asia during the Cold War era.
Efficient high harmonics generation by enhancement cavity driven with a post-compressed FCPA laser at 10 MHz

Published: May 2018

Efficient high harmonics generation (HHG) was demonstrated at 10 MHz repetition rate with an external femtosecond enhancement cavity, seeded by a ${\sim}70~\text{fs}$ post-compressed 10 MHz fiber chirped pulse amplifier (FCPA) laser. Operation lasting over 30 min with 0.1 mW outcoupled power at 149 nm was demonstrated. It was found that shorter pulse was beneficial for alleviating the nonlinear plasma effect and improving the efficiency of HHG. Low finesse cavity can relax the plasma nonlinearity clamped intra-cavity power and improve the cavity-locking stability. The pulse duration is expected to be below 100 fs for both 1040 nm and 149 nm outputs, making it ideal for applications such as time-resolved photoemission spectroscopy.
Dynamics of a perturbed solid-body rotation flow in a finite-length straight rotating pipe
Authors: Feng Chunjuan , Liu Feng , Rusak Zvi , Wang Shixiao 
Published: May 2018

Direct numerical simulations are used to study the three-dimensional, incompressible and viscous flow dynamics of a base solid-body rotation flow with a uniform axial velocity entering a rotating, finite-length, straight circular pipe. Steady in time profiles of the axial, radial and circumferential velocities are prescribed along the pipe inlet. The convective boundary conditions for each velocity flux component is set at the pipe outlet. The simulation results describe the neutral stability line in response to either axisymmetric or three-dimensional perturbations in a diagram of Reynolds number ($Re$, based on inlet axial velocity and pipe radius) versus the incoming flow swirl ratio ($\unicode[STIX]{x1D714}$). This line is in good agreement with the neutral stability line recently predicted by the linear stability theory of Wang et al. (J. Fluid Mech., vol. 797, 2016, pp. 284–321). The computed time history of the velocity components at a certain point in the flow is used to describe three-dimensional phase portraits of the flow global dynamics and its long-term behaviour. They show three types of flow evolution scenarios. First, the Wang & Rusak (Phys. Fluids, vol. 8 (4), 1996, pp. 1007–1016) axisymmetric instability mechanism and evolution to a stable axisymmetric breakdown state is recovered at certain operational conditions in terms of $Re$ and $\unicode[STIX]{x1D714}$. However, at other operational conditions with same $\unicode[STIX]{x1D714}$ but with a higher $Re$, a second scenario is found. The axisymmetric breakdown state continues to evolve and a spiral instability mode appears on it and grows to a rotating spiral breakdown state. Moreover, at higher levels of $\unicode[STIX]{x1D714}$ a third scenario is found where there exists a dominant three-dimensional spiral type of instability mode that agrees with the linear stability theory of Wang et al. (J. Fluid Mech., vol. 797, 2016, pp. 284–321). The growth of this mode leads directly to a spiral type of flow roll-up and nonlinearly saturates on a rotating spiral type of vortex breakdown. The Reynolds–Orr equation is used to reveal the mechanism that drives all the instabilities as well as the nonlinear global flow evolution. At high swirl ratios, the confined kinetic energy in the swirling flow can be triggered to be released through various physical agents, such as the asymmetric inlet–outlet conditions, that eliminate axial homogeneity along the pipe and induce flow instabilities and evolution to breakdown states. It is also shown that local instability analysis or its extension using the assumption of a weakly non-parallel flow to conduct convective instability–absolute instability analyses is definitely not related to any of the instability modes found in the present study. Moreover, a stability study based on the strongly non-parallel flow character, including axial inhomogeneity due to a finite-domain boundary conditions, must be conducted to reveal instabilities in such flows.
Cannabinoid signalling in embryonic and adult neurogenesis: possible implications for psychiatric and neurological disorders

Published: May 2018

AbstractCannabinoid signalling modulates several aspects of brain function, including the generation and survival of neurons during embryonic and adult periods. The present review intended to summarise evidence supporting a role for the endocannabinoid system on the control of neurogenesis and neurogenesis-dependent functions. Studies reporting participation of cannabinoids on the regulation of any step of neurogenesis and the effects of cannabinoid compounds on animal models possessing neurogenesis-dependent features were selected from Medline. Qualitative evaluation of the selected studies indicated that activation of cannabinoid receptors may change neurogenesis in embryonic or adult nervous systems alongside rescue of phenotypes in animal models of different psychiatric and neurological disorders. The text offers an overview on the effects of cannabinoids on central nervous system development and the possible links with psychiatric and neurological disorders such as anxiety, depression, schizophrenia, brain ischaemia/stroke and Alzheimer’s disease. An understanding of the mechanisms by which cannabinoid signalling influences developmental and adult neurogenesis will help foster the development of new therapeutic strategies for neurodevelopmental, psychiatric and neurological disorders.
Episodes of Translation and Network Resilience: Lessons from Israel's Attempted Institutionalisation of Workfare
Authors: HELMAN SARA , MARON ASA 
Published: May 2018

AbstractThe translation perspective explores the travel of policy ideas, programmes and practices across international boundaries, focusing on the process through which interpretative agents introduce and adjust borrowed policy items to a new policy context. Current research emphasises the significance of local networks’ support for translation's efficacy. However, we know little about how such networks are maintained and stabilized over time or how changing configurations and capacities may affect translation's prospects. This paper explores the case of Israel's attempted institutionalisation of workfare – an enduring international policy fashion – from 1998 to the present day. We follow the stabilization and destabilization of the local translation network across different levels and sites of policy design and implementation, analysing emerging conflicts and agreements at each site. We use the metaphor ‘episodes of translation’ to explore translation's value as a concept accounting for local policy change. In order for translation-led policy change to maintain legitimacy and actualisation in contested domains, ongoing engagement of existing and emerging policy actors is essential. This case demonstrates how when networks become destabilized, translation-led policy change may come to a halt.

AbstractIn 2017 Zagreb faced the largest outbreak of haemorrhagic fever with renal syndrome (HFRS) to date. We investigated to describe the extent of the outbreak and identify risk factors for infection. We compared laboratory-confirmed cases of Hantavirus infection in Zagreb residents with the onset of illness after 1 January 2017, with individually matched controls from the same household or neighbourhood. We calculated adjusted matched odds ratios (amOR) using conditional logistic regression. During 2017, 104 cases were reported: 11–81 years old (median 37) and 71% (73) male. Compared with 104 controls, cases were more likely to report visiting Mount Medvednica (amOR 60, 95% CI 6–597), visiting a forest (amOR 46, 95% CI 4.7–450) and observing rodents (amOR 20, 95% CI 2.6–159). Seventy per cent of cases (73/104) had visited Mount Medvednica prior to infection. Among participants who had visited Mount Medvednica, cases were more likely to have drunk water from a spring (amOR 22, 95% CI 1.9–265), observed rodents (amOR 17, 95% CI 2–144), picked flowers (amOR 15, 95% CI 1.2–182) or cycled (amOR 14, 95% CI 1.6–135). Our study indicated that recreational activity around Mount Medvednica was associated with HFRS. We recommend enhanced surveillance of the recreational areas during an outbreak.
URBAN DEPRAVITY, RURAL UNSOPHISTICATION: HEREDITARY TAINT IN HARDY'STESS OF THE D'URBERVILLES
Authors: Nunan Rosanna 
Published: May 2018

Critics have used various approachesto explain the paradoxes or inconsistencies evident in the characterization of Angel Clare in Thomas Hardy'sTess of the D'Urbervilles(1891); however, by examining the social purity movement and its response to increasingly popular theories of degeneration at the fin de siècle, we can understand the interplay of contradictory ideas at work in Angel. The tension between the supposedly modern, secular viewpoints that Angel exhibits in the beginning of the narrative and his unexpected return to a conservative and misogynistic ideology upon Tess's confession of her “fall” puzzles readers, fellow characters, and perhaps even the narrator of the novel itself, who accounts for the alteration as simply the hypocrisy of a man who “was yet the slave to custom and conventionality when surprised back into his early teachings” (Hardy 265; vol. 2, ch. 39). Oliver Lovesey suggests that the reason why “Clare somewhat bombastically renounces his father's Christianity, but . . . still stumbles on elements of traditional social morality” and why he “bypasses the resurrection, but cannot negotiate around Tess's ‘unintact state’” is that Tess's “virginity replaces the resurrection in his religion of unbelief” (913–14). Lovesey argues that Angel displaces religious faith in Christ's resurrection onto a material substitute, Tess's virginity, and that the revelation of her lack of virginity then catapults him into a despair akin to the despair of annihilated spiritual belief, “the void of an unbeliever's hell” (924). While I am also concerned with Angel's fetishization of virginity, I believe that it is significant that his obsession with purity extends beyond Tess's virginity to encompass rural space as a whole, a space in which Tess's virginity constitutes but one part. The very capaciousness of Angel's devotion to purity situates him squarely within the environmental binaries characteristic of later theories of urban degeneration.
