Event tree algorithms to generate test sequences for composite Web services
Authors: Endo Andre Takeshi , Simao Adenilso 
Published: June 2017

SummaryIn service‐oriented architecture testing, the behaviour of a composite service and its partner services can be represented as an event graph (model). As test cases are derived from such a model, the Chinese postman problem (CPP) algorithm is applied to cover all edges. Although CPP provides an optimal solution, there is a lack of alternative algorithms to obtain not only a faster execution but also a satisfactory solution. This paper introduces the event tree algorithm (ETA) to generate test cases from event sequence models for Web service compositions. Two strategies are also proposed to improve ETA: First, a greedy strategy to build the tree is defined based on the cost of expanding given edges. Second, redundant elements are eliminated (pruned) in the tree. Four versions of ETA are compared with CPP with respect to test suite size, generation time, number of test sequences, and test sequence length.

Published: June 2017

AbstractThis study investigates the effect of a Framework‐aligned professional development program at the PreK‐3 level. The NSF funded program integrated science with literacy and mathematics learning and provided teacher professional development, along with materials and programming for parents to encourage science investigations and discourse around science in the home. This quasi‐experimental study used a three‐level hierarchical linear model to compare the Renaissance STAR Early Literacy, Reading, and Mathematics scores from 2015 to 2016 of K‐3 students in treatment and control classrooms in a large Midwestern urban school district. The statistically significant results indicate that, on average, every year that a student has a program teacher adds 8.6 points to a student's spring STAR Early Literacy score, 17.0 points to a student's STAR Mathematics score, and 41.4 points to a student's STAR Reading score compared to control students. Implications for early elementary teacher education and policy are discussed. © 2017 Wiley Periodicals, Inc. J Res Sci Teach 54:1174–1196, 2017
Introduction
Authors: Zimmermann Martina 
Published: June 2017

AbstractThe introduction gives an overview on sociopolitical and research-related developments regarding dementia, and attempts explanations for why the interest in dementia of critical scholarship continues to be very limited and particularly focused on caregiver accounts. It illustrates that an understanding of the obvious neglect of dementia patient narratives sheds some light onto the ethical implications and challenges of critically reading such narratives: these narratives seem least of all fit to match classical survivor illness literature, and serious impairment in the ability to tell or understand stories has been taken as motivation to neglect patient narratives. Approaches highlighting the importance of pre-narrative identity and a growing body of psycho-philosophical work demand a closer scrutiny of patient narratives, which would also amplify their author-narrators’ advocacy.
Conclusion
Authors: Zimmermann Martina 
Published: June 2017

AbstractThe conclusion considers the changes both caregiver and patient life-writing have gone through over a thirty-year period. It identifies these changes in a multilanguage approach as, partly, conditioned by the rising number of individuals with dementia and the increasing societal presence of the disease. At the same time, these changes have propelled forward a patient-centred development. More and more patients aim actively to participate in shaping the mainstream dementia discourse, which especially involves shifting notions of selfhood. A deliberation on very recent third-person caregiver narratives, including a graphic novel and a film documentary, highlights that this evolution in patient perception has reached broader societal levels, and promises to shift values in healthcare planning and socio-economic as well as cultural approaches to the condition.
The Quality of MOOCs: How to Improve the Design of Open Education and Online Courses for Learners?
Authors: Stracke Christian M. 
Published: June 2017

AbstractThis paper presents the current status of Open Education and MOOCs and discusses their quality following the main question: How can we introduce new design and evaluation methods and personalization strategies to improve the learning quality of Open Education? First, the dimensions of Open Education are differentiated. Then the dimensions of holistic quality development are transferred to Open Education and discussed for the design of MOOCs leading to recommendations for personalization. A new quality indicator for evaluating the quality of MOOCs is introduced: It is proposed not to measure the traditional drop-out rates but the completion of individual goals and intentions by the MOOC learner. It is concluded that Open Education and MOOCs have got the potential for the next revolution in learning experiences.
Experienced vs. inexperienced participants in the lab: do they behave differently?
Authors: Benndorf Volker , Moellers Claudia , Normann Hans-Theo 
Published: June 2017

AbstractWe analyze whether subjects with extensive laboratory experience and first-time participants, who voluntarily registered for the experiment, differ in their behavior. Subjects play four one-shot, two-player games: a trust game, a beauty contest, an ultimatum game, a traveler’s dilemma and, in addition, we conduct a single-player lying task and elicit risk preferences. We find few significant differences. In the trust game, experienced subjects are less trustworthy and they also trust less. Furthermore, experienced subjects submit fewer non-monotonic strategies in the risk elicitation task. We find no differences whatsoever in the other decisions. Nevertheless, the minor differences observed between experienced and inexperienced subjects may be relevant because we document a potential recruitment bias: the share of inexperienced subjects may be lower in the early recruitment waves.
Comparison of variational balance models for the rotating shallow water equations
Authors: Dritschel David G. , Gottwald Georg A. , Oliver Marcel 
Published: June 2017

We present an extensive numerical comparison of a family of balance models appropriate to the semi-geostrophic limit of the rotating shallow water equations, and derived by variational asymptotics in Oliver (J. Fluid Mech., vol. 551, 2006, pp. 197–234) for small Rossby numbers$Ro$. This family of generalized large-scale semi-geostrophic (GLSG) models contains the$L_{1}$-model introduced by Salmon (J. Fluid Mech., vol. 132, 1983, pp. 431–444) as a special case. We use these models to produce balanced initial states for the full shallow water equations. We then numerically investigate how well these models capture the dynamics of an initially balanced shallow water flow. It is shown that, whereas the$L_{1}$-member of the GLSG family is able to reproduce the balanced dynamics of the full shallow water equations on time scales of$O(1/Ro)$very well, all other members develop significant unphysical high wavenumber contributions in the ageostrophic vorticity which spoil the dynamics.
High precision U/Th dating of the rock paintings at Mt. Huashan, Guangxi, southern China

Published: June 2017

AbstractThe rock art and the associated natural scenery at 38 sites located in the Zuojiang River valley, in the southwest of Guangxi Zhuang Autonomous Region, southern China, were inscribed recently on UNESCO’s World Heritage List. The painted panel at the site of Mt. Huashan is probably the largest known rock art panel in the world, consisting of approximately 1900 identifiable figures and occupying an area of approximately 8000 m2. To determine a precise age on the rock art at Mt. Huashan, 56 secondary carbonate layers above and below the paintings were studied for their mineralogy, oxygen, and carbon isotopic compositions and dated by the 230Th/U method. The 230Th/U dating results demonstrate that ages of the rock paintings can be bracketed between 1856±16 and 1728±41yr BP corresponding to the middle to the end of the Eastern Han dynasty (AD 25 to 220). The results imply that the rock painting practices at Mt. Huashan probably lasted more than a century, and the Zuojiang rock art is younger than that at Baiyunwan and Cangyuan in Yunnan Province by 1 to 10 centuries.
The Company Oracle: Corporate Security and Diviner-Detectives in Angola's Diamond Mines
Authors: Calvão Filipe 
Published: June 2017

AbstractIn 1957, the security force of Angola's colonial diamond mining company recruited African diviners to help them solve a case of diamond theft in Lunda. This event reveals a peculiar convergence of divinatory practices with techniques of corporate surveillance in Lunda's political economy of security. In their overlapping features of secrecy and control, divination and corporate security can be understood as historically aligned evidentiary practices, or what I call “corporate divination.” By examining divinatory rituals in tandem with the “occult” apparatus of corporate surveillance, and the figure of a colonial sorcerer-detective renowned for his “divinatory” prowess, I ask how such seemingly opposed modes of knowledge production eroded or shored up colonial rule. The cultural significance of divination within the context of a mining company, I suggest, exposes the conditions under which a colonial corporation appropriates the social world in which it intervenes, and conversely, the cultural resources that potentially shape or undermine corporate life in a colonial context.
Oil in the Caribbean: Refineries, Mangroves, and the Negative Ecologies of Crude Oil
Authors: Bond David 
Published: June 2017

AbstractThis article links up the disastrous history of fossil fuels with the celebrated ecology of mangroves. Building on ethnographic and historical research in Puerto Rico and St. Croix, it outlines the often neglected but quite consequential place of crude oil in the Caribbean. Following the construction of what became the second largest refinery in the world, I describe how the imperial energy networks of the United States first came to the Caribbean. Troubling a popular origin story of the Caribbean, colonial and industry leaders voiced a robust critique of the plantation in order to justify the introduction of these enclave refineries. Imperial energy networks welcomed an unprecedented problem to the region: coastal oil spills. The scientific and legal response to these spills brought new attention to the vital relationality of mangroves. Rather perversely, the destruction of the mangroves in the Caribbean—in which crude oil played the leading role—opened mangroves up to new forms of knowledge and care. While many claim that fossil fuels helped cultivate a modern disregard for the natural world, I show how the negative ecologies of fossil fuels also instigated new scientific and political appreciations for the liveliness of the natural world. This story of oil in the Caribbean has implications for scholarly debates around the so-called Anthropocene. Against scholarship that looks at the coming disaster of crude oil as an epochal break in thought and politics, this paper instead describes the long history of acknowledging and managing the disastrous qualities of fossil fuels.
Insurgent Rule as Sovereign Mimicry and Mutation: Governance, Kingship, and Violence in Civil Wars
Authors: Klem Bart , Maunaguru Sidharthan 
Published: June 2017

AbstractThis article uses the case of the Liberation Tigers of Tamil Eelam (LTTE) to make a conceptual argument about sovereignty. Despite its aura of natural order, sovereignty is ultimately self-referential and thus somewhat arbitrary and potentially unstable. At the heart of this unsteadiness, we posit, lies the paradox between the systematic tenets of rational governance and the capricious potential of sublime violence. Both are highly relevant to the LTTE case: the movement created de facto state institutions to mimic governance, but simultaneously deployed an elaborate transcendental register of sacrifice, meaning, and intractable power wielded by a mythical leader. To capture this paradox, we connect the literature on rebel governance with anthropological debates about divine kingship. We conceptualize sovereignty as a citational practice that involves the adaptation, imitation, and mutation of different idioms of authority: political and religious, modern and traditional, rational and mythical. Understanding sovereignty in this way debunks the idea that insurgent movements are merely lagging behind established states. As sites of mimicry, bricolage, and innovation, they transform the way sovereignty is practiced and understood, thus affecting the frame that sovereignty is.
Debt and Its Attachments: Collateral as an Object of Knowledge in Nineteenth-Century Liberalism
Authors: Suter Mischa 
Published: June 2017

AbstractThis essay partakes in the dialogue between history, anthropology, and social theory on the topic of debt as a social relation. Drawing on sources from nineteenth-century Switzerland, it examines everyday routines of debt collection in liberalism by taking the seized collateral object to the center of historical analysis. It is shown how the attached goods in a debtor's household became an object of knowledge for nineteenth-century framers of law as well as for ordinary debtors. I make use of anthropological theory in order to describe the legal techniques of delineating and extracting collateral, and show how these legal techniques implied specific knowledge practices. I then look at two borderline cases of collateralization: the pawning of mobile goods and the imprisonment of insolvent debtors. Further, I discuss how, by the 1880s, the limits of debt collection were debated, when certain goods were exempt for seizure in a projected federal law. Overall, on an epistemological level, debt collection appears as a double movement: it provided basic tools to untangle property relationships, yet all the while it created new, unpredictable complications. Thus debt collection was a distinctive arena in which the uneasy conceptual relationship between people and things in nineteenth-century liberalism unfolded. From this conceptual node I propose a historical epistemology of the collateral object.

SUMMARYGenotype by environment (G x E) interactions for grain yield were investigated in 13 perennial rice (Oryza sativa L./Oryza longistaminata) derivatives over three sites and 2 years in Lao PDR. Genotype accounted for 29.0% of the total sum of squares, with environment and the G x E interaction responsible for 60.2 and 10.8%, respectively. Cluster analysis identified three environment and six genotype groups, which accounted for 49.7, 98.0 and 42.8% of the E, G and G x E sums of squares, respectively. Principal component axes 1, 2 and 3 accounted for 54.0, 30.6 and 11.7% of the G x E sum of squares, respectively, with PCA1 indicating yield potential, PCA2 timing of cessation of rainfall in the 2011 wet season, and PCA3 environmental stresses affecting regrowth in the 2012 wet season. Genotype groups differed in adaptation to these contrasting conditions. G6 (Line 213, 240 and RD23) was widely adapted to all environments, with G5 (Line 248) being especially adapted to the 2012 environments. G3 and G4 were neutral, though G3 (Line 53) showed some preference for the Na Pok environments. G1 and G2 were poorly adapted everywhere, with the tall and late G1 (Line 11) being especially poor at Na Pok 2011 in a dry finish. While yields were lower in 2012, all derivatives survived the dry season with access to life-saving irrigation. This is promising, as the annual rice RD23 was unable to ratoon under these conditions, and had to be re-sown. Importantly, Line 213, 240 and 248 yielded comparably to RD23 from regrowth in 2012. Development of perennial rice should target rainfed and especially upland environments.
‘A BEACON OF HOPE FOR THE COMMUNITY’: THE ROLE OF CHAVAKALI SECONDARY SCHOOL IN LATE COLONIAL AND EARLY INDEPENDENT KENYA
Authors: SAETEURN MUEY CHING 
Published: June 2017

AbstractSituated in the densely populated former North Nyanza District of western Kenya, Chavakali secondary school was the site where the colonial regime, the nationalist government, and international ‘developmentalists’ attempted to dictate the nature of education and by extension the place of the rural citizenry during the late 1950s and throughout the 1960s. This goal, however, was not easily achieved because ordinary Kenyans rejected the vocational-agricultural curriculum that school officials and development specialists championed as the ideal education program for rural communities. Chavakali students from Maragoliland, in particular, recognized the inherent contradiction of the Kenyan government's agriculture-as-development model continued from the colonial era – lack of land. Realizing how bankrupt the agrarian development model really was, they used their educational training to enter the wage labor sector on better terms than as simple laborers. Chavakali's nonsensical curriculum thus hardly produced the agrarian revolution that the state hoped would stabilize the countryside in the postcolony.
THE ‘INTERIOR WORLD’ OF THE NINETEENTH-CENTURY MALOTI-DRAKENSBERG MOUNTAINS
Authors: KING RACHEL , CHALLIS SAM 
Published: June 2017

AbstractOver the last four decades researchers have cast the Maloti-Drakensberg Mountains as a marginal refuge for ‘Bushmen’ amidst constricting nineteenth-century frontiers. Rock art scholarship has expanded on this characterisation of mountains as refugia, focusing on heterogeneous raiding bands forging new cultural identities. Here, we propose another view of the Maloti-Drakensberg: a dynamic political theatre in which polities that engaged in illicit or ‘heterodox’ activities like cattle raiding and hunter-gatherer lifeways set the terms of colonial encounters. We employ the concept of the ‘interior world’ to refigure the region as one fostering subsistence and political behaviours that did not conform to the expectations of colonial authority. Paradoxically, such heterodoxies over time constituted widespread social logics within the Maloti-Drakensberg, and thus became commonplace and meaningful. We synthesise historical and archaeological evidence (new and existing) to illustrate the significance of the nineteenth-century Maloti-Drakensberg, offering a revised southeast-African colonial landscape and directions for future research.
MAKING RAIN, MAKING MAPS: COMPETING GEOGRAPHIES OF WATER AND POWER IN SOUTHWESTERN AFRICA
Authors: MCKITTRICK MEREDITH 
Published: June 2017

AbstractThis article explores the alchemy whereby ritual and political worlds invisible to Europeans were rendered visible on European maps. It begins with a puzzle: representations of southwestern Africa's rivers on those maps bear little resemblance to physical reality as the cartographers would have understood it. Using GIS technology to georeference a series of maps and highlight the placement of rivers on them illustrates the convergence of cartographers’ representations and regional political cosmologies linking power to control over water. Travelers’ accounts and colonial archives illuminate how knowledge was produced and why African ideas about geography were inadvertently embedded in those maps well into the twentieth century. This method opens a window into otherwise-obscured African intellectual history and demonstrates that even something as apparently and unambiguously ‘European’ as modern mapping was the result of on-the-ground negotiations well into the colonial period.
MAU MAU'S ARMY OF CLERKS: COLONIAL MILITARY SERVICE AND THE KENYA LAND FREEDOM ARMY IN KENYA'S NATIONAL IMAGINATION
Authors: PARSONS TIMOTHY H. 
Published: June 2017

AbstractScholarly and popular histories of Kenya largely agree that African Second World War veterans played a central role in the Kenya Land Freedom Army. Former African members of the colonial security forces have reinforced these assumptions by claiming to have been covert Mau Mau supporters, either after their discharge, or as serving soldiers. In reality, few Mau Mau generals had actual combat experience. Those who served in the colonial military usually did so in labor units or support arms. It therefore warrants asking why so many Kenyans accept that combat veterans played such a central role in the KLFA and in Kenyan history. Understanding how veterans of the colonial army have become national heroes, both for their wartime service and their supposed leadership of Mau Mau, reveals the capacity of popular history to create more useful and inclusive forms of African nationalism.

BackgroundPsychotic symptoms are common in children and adolescents and may be early manifestations of liability to severe mental illness (SMI), including schizophrenia. SMI and psychotic symptoms are associated with impairment in executive functions. However, previous studies have not differentiated between ‘cold’ and ‘hot’ executive functions. We hypothesized that the propensity for psychotic symptoms is specifically associated with impairment in ‘hot’ executive functions, such as decision-making in the context of uncertain rewards and losses.MethodsIn a cohort of 156 youth (mean age 12.5, range 7–24 years) enriched for familial risk of SMI, we measured cold and hot executive functions with the spatial working memory (SWM) task (total errors) and the Cambridge Gambling Task (decision-making), respectively. We assessed psychotic symptoms using the semi-structured Kiddie Schedule for Affective Disorders and Schizophrenia interview, Structured Interview for Prodromal Syndromes, Funny Feelings, and Schizophrenia Proneness Instrument – Child and Youth version.ResultsIn total 69 (44.23%) youth reported psychotic symptoms on one or more assessments. Cold executive functioning, indexed with SWM errors, was not significantly related to psychotic symptoms [odds ratio (OR) 1.36, 95% confidence interval (CI) 0.85–2.17, p = 0.204). Poor hot executive functioning, indexed as decision-making score, was associated with psychotic symptoms after adjustment for age, sex and familial clustering (OR 2.37, 95% CI 1.25–4.50, p = 0.008). The association between worse hot executive functions and psychotic symptoms remained significant in sensitivity analyses controlling for general cognitive ability and cold executive functions.ConclusionsImpaired hot executive functions may be an indicator of risk and a target for pre-emptive early interventions in youth.
