Unexpected Cancellations in Gravity Theories

Recent computations of scattering amplitudes show that N = 8 supergravity is surprisingly well behaved in the ultraviolet and may even be ultraviolet finite in perturbation theory. The novel cancellations necessary for ultraviolet finiteness first appear at one loop in the guise of the ''no-triangle hypothesis''. We study one-loop amplitudes in pure Einstein gravity and point out the existence of cancellations similar to those found previously in N = 8 supergravity. These cancellations go beyond those found in the one-loop effective action. Using unitarity, this suggests that generic theories of quantum gravity based on the Einstein-Hilbert action may be better behaved in the ultraviolet at higher loops than suggested by naive power counting, though without additional (supersymmetric) cancellations they diverge. We comment on future studies that should be performed to support this proposal.
Haptic robot-environment interaction for self-supervised learning in ground mobility

This dissertation presents a system for haptic interaction and self-supervised learning mechanisms to ascertain navigation affordances from depth cues. A simple pan-tilt telescopic arm and a structured light sensor, both fitted to the robot’s body frame, provide the required haptic and depth sensory feedback. The system aims at incrementally develop the ability to assess the cost of navigating in natural environments. For this purpose the robot learns a mapping between the appearance of objects, given sensory data provided by the sensor, and their bendability, perceived by the pan-tilt telescopic arm. The object descriptor, representing the object in memory and used for comparisons with other objects, is rich for a robust comparison and simple enough to allow for fast computations. The output of the memory learning mechanism allied with the haptic interaction point evaluation prioritize interaction points to increase the confidence on the interaction and correctly identifying obstacles, reducing the risk of the robot getting stuck or damaged. If the system concludes that the object is traversable, the environment change detection system allows the robot to overcome it. A set of field trials show the ability of the robot to progressively learn which elements of environment are traversable. keywords: autonomous robots, self-supervised learning, affordances, terrain assessment, depth sensing, robotic arm.
Towards a CAT tool agnostic standard for User Activity Data

The dominance of the source word pricing model combined with the fact that most translators work as freelancers has led to a scenario in which until recently most buyers (direct and intermediary) who work with freelancers neither knew nor cared how many words per hour the translators they hire translate. However, this situation is beginning to change. Machine translation has shown that it is possible for translation requesters to impact positively on words per hour productivity. In addition to classical full-sentence MT, advances in various typeahead technologies have resulted in a situation in which a number of options are available to impact positively on a translator’s working speed and terminological consistency with previous translations. Finally, evidence is beginning to emerge that productivity gains can be achieved where translators use Automatic Speech Recognition to dictate rather that type the target text. In this paper we will provide a brief overview of these technologies and use cases the impact on translator productivity and describe an architecture to gather translation process data to measure their impact from working translators in a maximally unobtrusive way. We propose an open-standard for User Activity Data in CAT tools (CAT-UAD) so that they can work in any CAT tool that implements this standard and outline a technical architecture to gather such data conveniently and a privacy model that respects translator, intermediary and end-client data sharing concerns and discuss various A/B testing scenarios that can be tested using Segment Level A/B testing.
How to Target Households in Adaptive Social Protection Systems? Evidence from Humanitarian and Development Approaches in Niger

Abstract The methods used to identify the beneficiaries of programmes aiming to address persistent poverty and shocks are subject to frequent policy debates. Relying on panel data from Niger, this report simulates the performance of various targeting methods that are widely used by development and humanitarian actors. The methods include proxy-means testing (PMT), household economy analysis (HEA), geographical targeting, and combined methods. Results show that PMT performs more effectively in identifying persistently poor households, while HEA shows superior performance in identifying transiently food insecure households. Geographical targeting is particularly efficient in responding to food crises, which tend to be largely covariate. Combinations of geographical, PMT, and HEA approaches may be used as part of an efficient and scalable adaptive social protection system. Results motivate the consolidation of data across programmes, which can support the application of alternative targeting methods tailored to programme-specific objectives.
Use of bottom-mounted echo sounders in exploring behavior of mesopelagic fishes

We deployed an upward-facing echo sounder mounted on the bottom and cabled to shore in a ~400 m fjord location for long-term studies of small mesopelagic fish and their potential predators. The population of the myctophid Benthosema glaciale displayed diverse diel vertical migration (DVM) behaviors, including normal DVM to surface waters at night, reverse DVM in the lower part of the water column in which fish ascended to ~200 m at day, as well as nonmigration of some individuals. The relative prevalence of these behavioral modes varied with season. Acoustic target tracking of individuals in deep water showed that B. glaciale was conspicuously inactive and drifted back and forth with weak tidal currents, essentially acting as plankton. Swimming was largely restricted to infrequent short bouts. More active swimming occasionally occurred in the vertical direction, and then in a stepwise pattern. Potential predators in deep water were swimming at speeds of <0.5 body length s–1, with maximum speeds of ~1 body length s–1. These results show that submerged echo sounders provide a means of non-intrusively studying both individual and population behavior of deep-living organisms.
Reduction in methane emissions from ruminants by plant secondary metabolites: effects of polyphenols and saponins.

The effects of plant secondary metabolites (PSM), specifically polyphenols (tannins) and saponins on rumen fermentation and methanogenesis were investigated using the Hohenheim gas method. We evaluated the effects of: (1) polyphenol-containing plants, (2) simple phenols in the form of phenolic acids, (3) purified tannins, (4) saponin-containing plants, and (5) isolated saponin-rich fractions on rumen methanogenesis. Statistically significant negative relationships between total phenols, total tannins or tannin activity and methane (CH4) production were observed, whereas no correlation existed between condensed tannins and CH4 production. Cinnamic, caffeic, p-coumaric and ferulic acids decreased CH4 production significantly when added at 5 mM. Addition of purified chestnut and sumach tannins (hydrolysable tannins) at 1 mg/mL to the in vitro rumen fermentation system containing hay:concentrate (70:30) decreased CH4 production (P < 0.05), by 6.5 and 7.2% respectively. However, addition of mimosa and quebracho tannins (condensed tannins) at this concentration did not decrease CH4 production. For studying the effects of saponins, leaves of Sesbania, Knautia and seeds of Fenugreek, and their saponin-rich fractions were evaluated. Addition of Fenugreek and Sesbania plant materials to hay or the hayconcentrate mixture increased partitioning factor (PF, expressed as mg truly degraded substrate/mL gas produced; a measure of efficiency of microbial protein synthesis) and decreased CH4 production per unit substrate degraded. These plant materials and their saponin-rich fractions did not reduce CH4 production in absolute amounts despite decreases in protozoal numbers by 40–50%. The saponins altered the microbial community towards proliferation of fibre-degrading bacteria and inhibition of fungal population. The results with saponin-containing plant materials and their isolated fractions indicated a weak association between anti-protozoal activity of saponins and methanogenesis. Nevertheless, the saponin-containing plants possess potential to partition higher proportions of the substrate to microbial mass production

In ation-Target Expectations and Optimal Monetary Policy

Under credible in ation targeting, we suggest that, instead of forming a rational expectation, some rms ("in ation-targeters") might simply expect future in ation to always equal its target. This paper analyses the implications of this for optimal monetary policy in a standard new-Keynesian model. If shocks have any persistence and in ation-targeters are present, the optimal policy frontier is improved under discretion. Under commitment, although the gains from commitment are diminished (stabilisation bias is reduced), overall loss is still reduced relative to the rational expectations benchmark for plausible parameter values. These results formally show how policies which encourage expectations anchoring may be bene cial.
Effectiveness of Educational Program Based Cognitive Load in Learning Efficiency of Algebra Concepts Among 7th Grade Girl Students in Tehran

Background and Aims: Learning efficiency is based on mental effort and students’ academic performance and academic curriculums were planned without any attention to the cognitive effects in the traditional education System, thus the present study aimed to investigate the effectiveness of educational program based on cognitive load in learning efficiency of algebra concepts that conducted among 7th grade girl students in Tehran during the academic year 2015-2016. Methods: Thiswas a quasi-experimental study. The statistical population included all girl students of public schools in the 7th grade of 6th district of Tehran in the academic year 2015-2016. a sample of 56 students was selected through cluster random sampling method from two schools. The educational program based on the cognitive effects was run for 4 weeks and total of 8 sessions. The effectiveness of educational program was evaluated by a test of algebra concepts, educational program, efficiency measures of Pass and Merriënboer. The data were analyzed with multivariate covariance, Univariate analysis of variance and t- test by using Spss version 20 software. Results: Results showed that experimental group had high academic achievement ( F =18.71, p <.0001) and perceived low cognitive load ( F =15.70, p <.0001) compared to students in the control group. Also results showed learning efficiency of the experimental group was higher than the control group ( t =4.031, p <.01). Conclusions: Since combination of cognitive load and academic achievement determine the level of learning efficiency, so the design of educational program based on the cognitive effects can increase students' learning outcomes and minimize perceptual cognition .
The Effects Of Weather On Investor Behavior: A Study On Individual Turkish Stock Market Investors

This study aimed at revealing the effects of weather on the investment behaviors of individual investors transacting at BIST (Borsa Istanbul) in the 2009-2011 period, and determining whether the socio-economic and demographic characteristics of investors created any significant difference in those effects. Unlike other studies conducted on this subject, the present study employed real stock purchase and sales data belonging to investors. The analyses conducted demonstrated that the level of cloudiness and temperature were influential on investor behaviors, and the socioeconomic and demographic characteristics of investors created certain differences in those effects. The number of sunny days, the number of overcast days, and sunshine duration were seen to have no effect on investor behaviors.
Hospital Designs for Patients of Different Ages

The design of hospitals should consider the needs and preferences of the patients, but the preferences of adolescents have received little attention. This investigation analyzed adolescents’ preferences for diverse hospital designs and compared them with those of the adults in charge of their care. Participants included were 345 adolescents—88 of them hospitalized—76 parents, and 46 health professionals. They all assessed three pairs of photographs of different hospital settings. Quantitative analyses were performed of the choices, and qualitative analyses of their justifications. The results indicated high agreement among the groups about which atmosphere was preferable for children and for adults, and also—with nuances—about the suitability of the nonchild-like atmosphere for adolescents. No important differences were found between hospitalized and nonhospitalized adolescents’ responses. The qualitative analyses revealed significant differences between the adolescents’ and adults’ response models in their ratings of the hospital setting design. The adolescents’ perspective seemed more sensitive than that of the adults toward symbolic aspects and the needs, experiences, and emotions of hospital users. The authors’ work reveals the need to consider the perspective of adolescents on hospital design, which cannot be substituted by that of their parents or of the clinical staff.
Producing Friend Recommendations in a Social Bookmarking System by Mining Users Content

Social Bookmarking Systems (and Social Media Systems in general) are experiencing a quick growth in the number of active users. This expansion led to the well-known “social interaction overload” problem, that means that each user has too many potential people to interact with. In order to address this problem, user recommender systems are widely proposed in the social media literature to recommend friends or people to follow. Currently, there are no approaches able to produce friend recommendations in the Social Bookmarking Systems domain. In this paper we propose a friend recommendation algorithm for a Social Bookmarking System, based on low computational effort heuristics that allow real time applications. Experimental results show that, when users tag in the same way and are also interested in the same content, they can be recommended as friends. The proposed algorithm produces better results, with respect to policies that use only tags and do not consider content. Keywords—Social Bookmarking; Friend Recommendation; Tagging System.

Quality Life Insurance Service of Jiban Bima Corporation (JBC) of Bangladesh: An Empirical Study

The purpose of this paper is to assess customers’ general expectation and perception of insurers in terms of services offered at the insurance service counter (ISC). Besides, this paper also examines the relationship between the demographic factors and SERVQUAL mean score. The study utilized the survey approach. The result shows huge gap for tangible, reliability and responsiveness and shows highest gap between customers’ perception and expectation. This result demonstrates tangible as the most critical determinant of SERVQUAL measure for service quality. The other dimensions (assurance and empathy) also appear important but tangible dominates. Thus, results of this study underscore the need for insurance providers to gear customer services and quality improvement efforts towards components of tangible. The study intends to promote a better theoretical understanding and recognition of the complexities to service quality and its measurement. The challenge for insurance sector in Bangladesh remains the same that is to bring innovative solutions to client while making them realize the value of those services provided. When clients realize that quality is something that cannot be compromised, an organization has to survive in the competitive market managing high value service. Keywords : Service quality, Life Insurance, Customers’ expectation and perception, Customer satisfaction
Taxonomy of Manufacturing Flexibility at Manufacturing Companies Using Imperialist Competitive Algorithms, Support Vector Machines and Hierarchical Cluster Analysis

Manufacturing flexibility is a multidimensional concept and manufacturing companies act differently in using these dimensions. The purpose of this study is to investigate taxonomy and identify dominant groups of manufacturing flexibility. Dimensions of manufacturing flexibility are extracted by content analysis of literature and expert judgements. Manufacturing flexibility was measured by using a questionnaire developed to survey managers of manufacturing companies. The sample size was set at 379. To identify dominant groups of flexibility based on dimensions of flexibility determined, Hierarchical Cluster Analysis (HCA), Imperialist Competitive Algorithms (ICAs) and Support Vector Machines (SVMs) were used by cluster validity indices. The best algorithm for clustering was SVMs with three clusters, designated as leading delivery-based flexibility, frugal flexibility and sufficient plan-based flexibility.
PHYSICAL SCALING FOR WATER MIST FIRE SUPPRESSION - A DESIGN APPLICATION

The objective of this paper was to develop a water mist extinguishment design using physical scale modeling. This paper describes the basis of the simulation, the performance of water mist nozzles in a quarter-scale model, and the selection and validation of a design. The suppression scenario is combustible cargo on two covered open-bed trailer-trucks subjected to a large heptane pool fire of 3 m 2 . The scenario is the basis of a standard test for ships under Maritime Safety Committee Circular MSC 914. The scaling emphasizes flame radiation by varying the fuel radiative absorption coefficient. Design development tests at a quarter scale were done with both liquid and gas simulated pool fires with noncombustible commodities. Once a water mist design was accepted, in this case two L66-Bete swirl nozzles at 1.46 gpm (0.092 L⋅s -1 ) each, model tests were done with commodities, and validated at full-scale. Compliance to MSC 914 was achieved with two Bete-TF18 swirl nozzles at 30 gpm (1.89 L⋅s -1 ) each, consistent with the scaling prediction. Acceptable scaling was demonstrated for the fire and its suppression in this complex scenario.
Service-dominant logic as a future strategy : Case CCC Corporation Oy

Mattila, Heidi 2011. Service-dominant logic as.a future strategy. Case: CCC Corporation Oy. Master’s Thesis. Kemi-Tornio University of Applied Sciences. Business and Culture. Pages 92. Appendices 1-2. The focus of this thesis is service-dominant logic, a framework created by Stephen Vargo and Robert Lusch (2004), in the software business. The case company, CCC Corporation is used as an analysis point. The subject is approached through research questions which are as follows: 1) How does the case company implement servicedominant logic in Finland? 2) What is service-dominant logic in the software business? 3) Why is service-dominant logic important for the software business and 4) What competences are needed to have service-dominant logic in the software business? Qualitative study is the chosen research method for this thesis. Semi-structured interviews and document review are used as data gathering techniques. Interviews concerned managers in different operational areas of the case company, to gain a broader view on the subject. Theoretical framework and discussions concentrate on the service-dominant logic, its key concepts value and service and on competence domains. A cyclic pattern between service-dominant logic, service-orientation and customerorientation was discovered and the importance of the logic for the software business was recognised. Competence discussion derived from the discussion in project-based companies and the foundational principles of service-dominant logic. Different organisational and individual competences were defined as demands of the logic. Service-dominant logic was recognised as a potential strategy for the company and an implementation plan was created. The demands for changes in organisational structure, competence and process development and networking were the heaviest phases recognised in the implementation plan.
