Incentives in Hierarchies

This chapter provides an overview of incentive-based theories of hierarchies. Models of managers as supervisors are initially discussed, focusing on implications for organizational scale diseconomies and for problems of collusion. Thereafter attention shifts to the control loss associated with delegating decision-making to managers, and how these relate to monitoring, evaluation and managerial compensation. The benefits of delegation owing to renegotiation of contracts, costs of contractual complexity or communication are subsequently discussed. These issues are examined in the context of a three-layer single-branch hierarchy. Models of more complex hierarchies involving multiple layers, branches and different ways of grouping activities into departments are subsequently described. The chapter concludes with an assessment of the achievements and shortcomings of this literature.
Performance-Aware Management of Cloud Resources

The dynamic nature of the cloud environment has made the distributed resource management process a challenge for cloud service providers. The importance of maintaining quality of service in accordance with customer expectations and the highly dynamic nature of cloud-hosted applications add new levels of complexity to the process. Advances in big-data learning approaches have shifted conventional static capacity planning solutions to complex performance-aware resource management methods. It is shown that the process of decision-making for resource adjustment is closely related to the behavior of the system, including the utilization of resources and application components. Therefore, a continuous monitoring of system attributes and performance metrics provides the raw data for the analysis of problems affecting the performance of the application. Data analytic methods, such as statistical and machine-learning approaches, offer the required concepts, models, and tools to dig into the data and find general rules, patterns, and characteristics that define the functionality of the system. Obtained knowledge from the data analysis process helps to determine the changes in the workloads, faulty components, or problems that can cause system performance to degrade. A timely reaction to performance degradation can avoid violations of service level agreements, including performing proper corrective actions such as auto-scaling or other resource adjustment solutions. In this article, we investigate the main requirements and limitations of cloud resource management, including a study of the approaches to workload and anomaly analysis in the context of performance management in the cloud. A taxonomy of the works on this problem is presented that identifies main approaches in existing research from the data analysis side to resource adjustment techniques. Finally, considering the observed gaps in the general direction of the reviewed works, a list of these gaps is proposed for future researchers to pursue.
Global beef cattle methane emissions: yield prediction by cluster and meta-analyses

Methane yield values (MY; g methane/kg dry-matter intake) in beef cattle reported in the global literature (expanded MitiGate database of methane-mitigation studies) were analysed by cluster and meta-analyses. The Ward and k means cluster analyses included accounting for the categorical effects of methane measurement method, cattle breed type, country or region of study, age and sex of cattle, and proportion of grain in the diet and the standardised continuous variables of number of animals, liveweight and MY. After removal of data from outlier studies, meta-analyses were conducted on subsets of data to produce prediction equations for MY. Removing outliers with absolute studentised residual values of >1, followed by meta-analysis of data accounting for categorical effects, is recommended as a method for predicting MY. The large differences among some countries in MY values were significant but difficult to interpret. On the basis of the datasets available, a single, global MY or percentage of gross energy in feed converted to methane (Ym) value is not appropriate for use in Intergovernmental Panel on Climate Change (IPCC) greenhouse accounting methods around the world. Therefore, ideally country-specific MY values should be used in each country’s accounts (i.e. an IPCC Tier 2 or 3 approach) from data generated within that country.
Topical Distribution of the Subcutaneous Fat Tissue on some Parts and Regions of the Body in Children and Adolescents from South Bulgaria

ABSTRACT The purpose of this paper is to assess, in intersexual and interage aspects, the topical distribution of SFT on the various body parts and areas of children and adolescents from different territorial regions of southern Bulgaria. We transversally examined 1491 children and adolescents aged 10 to 17 years (753 girls and 738 boys) from schools in the municipalities of Plovdiv, Pazardjik, Haskovo, Svilengrad. The subjects were divided into 8 one-year age groups. We measured calliper-metrically the thicknesses of 9 SF on the body and limbs. The topical SFT distribution on different body parts and areas was estimated basing on the following ratios: Ratio of SFT—torso/limbs of 4 SF; Ratio of SFT—torso/limbs of 6 SF; Ratio of SFT—upper/lower torso—4 SF; Two Ratio of SFT—upper/lower limbs: (1) and (2). The results show that in students from both genders, the processes of redistribution of SFT on the upper and lower parts of the body are most intensive in the period 15–16 years. In boys there is a tendency towards an increase of the SFT on the upper torso—chest, while in girls—on the lower part the abdomen. Throughout the period 10–17 years, in both genders, the thickness of SFT is higher on the lower limbs in comparison with the upper limbs.
DRIVE-LAB: AN EXPERIMENTAL PLATFORM FOR USAGE-BASED CAR INSURANCE

Usage-based insurance (UBI) is currently surfacing both in research and within insurance companies. There are a lack of actual described UBI products, and those that exist are experimental and limited to small customer segments. Insurance companies are showing a clear interest in entering the market, but UBI as a product is complex, and little research exists when it comes to completely implemented products. In this paper, the authors describe the design, implementation and experimentation on Drive-LaB, a fully functional UBI platform. Drive-LaB lets users collect spatiotemporal data with their smartphone. The system uses this data to identify driving style and environmental context, to allow risk assessment associated with car insurance. Drive-LaB is supported by a complex backend system featuring an advanced data warehouse and computational logic to identify driver styles. It also offers an easy-to-use Android application frontend, allowing users to log trips and see detailed statistics on completed trips. Drive-LaB has been used for experiments, collecting more than 13.000 kilometers worth of data in roughly one month. This data has been used to validate the platform and display how the system performs in a
Contrasting physiological responses to high salinity between two varieties of corn 'Lluteño' (salt tolerant) and 'Jubilee' (salt sensitive)

'Lluteno' is the only one corn capable to prosper in the Valley of Lluta under saline conditions (EC = 9.1 dS m-1). This cultivar has been little studied and there is no current information about its growth and about the possible mechanisms involved in its tolerance to salts. The aim of this research was to compare the growth of young plants of corn ( Zea mays L.) 'Lluteno' to that of the bred 'Jubilee', both grown under different salt concentrations, to characterize the absorption and distribution of Na+ and other nutrients in the plant and to evaluate the effect of the saline conditions in the osmotic adjustment in both cultivars. The plants of 21 d old were subjected for 15 d to two saline treatments: 50 and 100 mM NaCl. The accumulation of DM was reduced from 5.12 to 1.80 g plant-1 in 'Jubilee' and 5.53 to 4.12 g plant-1 in 'Lluteno' (P ≤ 0.05). 'Lluteno' showed to be more tolerant to salt stress that 'Jubilee' by greatest accumulation of biomass under saline conditions, it was associated with a lower accumulation of Na+, steadiness of K+ and Ca2+ content and accumulation of osmolytes in leaves. The latter affecting positively the maintenance of relative water content and the osmotic adjustment of this cultivar in the leaves.
Software Architectural Design Ontology

: Software architecture plays a key role in software development but absence of formal description of software architecture causes different impede in software development. To cope with these difficulties, ontology has been used as artifact. This paper proposes ontology for software architectural design based on IEEE model for architecture description and Kruchten 4+1 model for viewpoints classification. For categorization of style and views, ISO/IEC 42010 has been used. Corpus method has been used to evaluate ontology. The main aim of the proposed ontology is to classify and locate software architectural design information.
Electro-Mechanical Coupling in a One-Dimensional Model of Heart Muscle fiber

Abstract We developed a mathematical model that describes heart muscle fiber as a one-dimensional continuous medium of electrically and mechanically coupled cardiomyocytes through which electrical excitation propagates and initiates muscle contraction. The generic model simulates bilateral relations between the electrical and the mechanical activity of cardiomyocytes in the tissue and accounts for both intracellular and intercellular electro-mechanical couplings and mechano-electric feedback mechanisms.
Induction of resveratrol biosynthesis in Vitis amurensis cells by heterologous expression of the Arabidopsis constitutively active, Ca-independent form of the AtCPK1 gene Running Title: CDPK effect on resveratrol production

In the present study, we established transgenic calli of Vitis amurensis that expressed a constitutively active, Ca-independent form of the AtCPK1 gene (AtCPK1-Ca) and calli with a non-active form of the gene. High-performance liquid chromatography with UV and highresolution mass-spectrometry revealed that the predominant metabolites synthesized in our transgenic callus cultures were trans-resveratrol di-glucoside, trans-piceid, trans-resveratrol, trans-ε-viniferin and trans-δ-viniferin. The resveratrol content in the AtCPK1-Ca-transformed callus cultures exceeded that in the control cultures up to 90-fold. Furthermore, the expression of the AtCPK1-Ca gene caused cell growth activation, which led to the enhancement of resveratrol production up to 137 times that of the control calli (69.7 mg L vs. 0.51 mg L). Real-time PCR analysis showed that AtCPK1-Ca overexpression caused increasing of the expression of the key enzymes of phenylpropanoid pathway of resveratrol biosynthesis, 4-coumarate-CoA ligases. Thus, heterologous expression of constitutively active CDPK genes can be used to bioengineer plant cell cultures that produce stilbenes. Possible mechanisms for AtCPK1-mediated signal transduction were proposed by the reconstruction of known protein-protein interactions within CPK1-assotiated protein modules.
Basic Writing: Curricular Interactions with New Technology.

: Based on a survey of Basic Writing teachers across the country, this article reports a variety of ways in which develapmental writing curricula have been changed by introduction of new technologies. The authors present findings related to classroom practice, teacher develop­ ment, and distribution of resources. In Basic Writing and developmental writing sites, several general patterns of computer use emerge: resistance, lack of infrastructure, uneven access to professional development among staff (many of whom are temporary or part-time), and lack o f visibility for successful efforts. In addition, isolated successes and imaginative implementations of emerging technology are reported.

Membrane Trafficking and Endothelial-Cell Dynamics During Angiogenesis

The formation of new blood vessels, or neovascularization, involves multiple processes, including cell proliferation and migration, cell-cell and cell-matrix adhesion, and tube morphogenesis. Neovascularization can occur through one of two events: vasculogenesis, the de novo formation of blood vessels from angioblasts; or angiogenesis, the extension of new vessels from a pre-existing vasculature. Among these, angiogenesis in particular is relevant throughout life; its dysregulation has been causally related to several disorders that involve malignancy, inflammation, and ischemia. Angiogenesis is thought to depend on a set of signaling proteins – including certain kinases, integrins and vascular endothelial growth factor receptor-2 (VEGFR2) – that are enriched in specific plasma membrane domains. Both physiological and pathological angiogenesis rely on intracellular trafficking, a process that governs signaling by such proteins, as well as cell motility.
A body-condition index for ursids

In this investigation a body-condition index (BCI) was developed for polar bears (Ursus maritimus), black bears (Ursus americanus), and grizzly bears (Ursus arctos), based on residuals from the regression of total body mass against a linear measure of size, straight-line body length (SLBL). Transformation of masslength data from 1198 polar bears, 595 black bears, and 126 grizzly bears to natural logarithms resulted in a linear relationship between mass and length. However, the relationship in polar bears differed from that in black and grizzly bears. SLBL had a close positive relationship with skeletal (bone) mass in polar bears (n = 31) and black bears (n = 33), validating the use of SLBL as an accurate index of body size. There was no correlation between SLBL and BCI for polar bears (r = 0.005, p = 0.87, n = 1198) or for black bears and grizzly bears (r = 0.04, p = 0.30, n = 721), indicating that the BCI was independent of body size. The BCI had a close positive relationship with true body condition, m.
Free actions on semiprime rings

We identify some situations where mappings related to left centralizers, derivations and generalized (α, β)-derivations are free actions on semiprime rings. We show that for a left centralizer, or a derivation T , of a semiprime ring R the mapping ψ : R → R defined by ψ(x) = T (x)x − xT (x) for all x ∈ R is a free action. We also show that for a generalized (α, β)-derivation F of a semiprime ring R, with associated (α, β)-derivation d, a dependent element a of F is also a dependent element of α + d. Furthermore, we prove that for a centralizer f and a derivation d of a semiprime ring R, ψ = d ◦ f is a free action.
Small noise asymptotic expansions for stochastic PDE's, I. The case of a dissipative polynomially bounded non linearity

We study a reaction-diusion evolution equation perturbed by a Gaussian noise. Here the leading operator is the innitesimal generator of a C0-semigroup of strictly negative type, the nonlinear term has at most polynomial growth and is such that the whole system is dissipative. The corresponding It^o stochastic equation describes a process on a Hilbert space with dissipative nonlinear drift and a Gaussian noise. Under smoothness assumptions on the non-linearity, asymptotics to all orders in a small parameter in front of the noise are given, with uniform estimates on the remainders. Applications to nonlinear SPDEs with a linear term in the drift given by a Laplacian in a bounded domain are included. As a particular example we consider the small noise asymptotic expansions for the stochastic FitzHugh-Nagumo equations of neurobiology around deterministic solutions. 2010 Mathematics Subject Classication.

A Reidemeister-Schreier theorem for finitely $L$-presented groups

We prove a variant of the well-known Reidemeister-Schreier theorem for finitely $L$-presented groups. More precisely, we prove that each finite index subgroup of a finitely $L$-presented group is itself finitely $L$-presented. Our proof is constructive and it yields a finite $L$-presentation for the subgroup. We further study conditions on a finite index subgroup of an invariantly finitely $L$-presented group to be invariantly $L$-presented itself.
A Survey on Deployment Methods in Wireless Sensor Networks

The efficiency of sensor networks depends on the coverage of the target area. Although, in general, a sufficient number of sensors are used to ensure a certain degree of redundancy in coverage, a good sensor deployment method is still necessary to balance the workload of sensors in target area. In a sensor network sensors can move around to self-deploy. The deployment deals with moving sensors from an initial unbalanced state to balanced state. Therefore, several optimization problems can be defined to minimize different parameters such as total moving distance, number of moves, communication cost. There is a unique problem called communication holes in sensor networks, areas not covered by any node. In this paper, we will work mainly to detect and remove communication hole in a heterogeneous wireless sensor network. For this we will study the existing techniques.
Intrinsic and Extrinsic Motives Support Adults’ Regular Physical Activity Maintenance

Abstract Motives for physical activity were compared between adults who either successfully or unsuccessfully maintained regular physical activity over the last 10 years. Adults age 28–45 (N=721) completed an online survey, reporting their current physical activity levels and self-determination theory (SDT) motives, as well as their physical activity levels at least 10 years prior. With participants’ current and retrospective reports of their physical activity, four sample subgroups were created, including maintainers, improvers, decliners, and sedentary. ANOVA analyses were used to examine differences in motives between physical activity maintenance groups. Those who successfully maintained regular physical activity (maintainers) reported higher intrinsic and extrinsic motives compared to those who were not regularly active (P<0.05). Interestingly, maintainers reported similar physical activity motives compared to those who reported increased physical activity over time. Among the current sample and consistent with theory, motives for physical activity significantly influenced participants’ long-term maintenance of regular physical activity. Future interventions should consider these constructs to promote sustained physical activity.
UvA-DARE ( Digital Academic Repository ) Bayesian model selection with applications in social science

Does psi exist? In a recent article, Dr. Bem conducted nine studies with over a thousand participants in an attempt to demonstrate that future events retroactively affect people’s responses. Here we discuss several limitations of Bem’s experiments on psi; in particular, we show that the data analysis was partly exploratory, and that one-sided p values may overstate the statistical evidence against the null hypothesis. We reanalyze Bem’s data using a default Bayesian t test and show that the evidence for psi is weak to nonexistent. We argue that in order to convince a skeptical audience of a controversial claim, one needs to conduct strictly confirmatory studies and analyze the results with statistical tests that are conservative rather than liberal. We conclude that Bem’s p values do not indicate evidence in favor of precognition; instead, they indicate that experimental psychologists need to change the way they conduct their experiments and analyze their data.

El Inventario de Dimensiones de Disciplina (DDI), Versión niños y adolescentes: Estudio de las prácticas de disciplina parental desde una perspectiva de género

Title: The Dimensions of Discipline Inventory (DDI)-Child and adoles- cent version: Analysis of the parental discipline from a gender perspective. Abstract: This study translated into Spanish the Discipline Dimensions Inventory for Children (DDI-C; Straus y Fauchier, 2007) and examined gender differences in the use of discipline. The results with a sample of 1371 children and adolescents confirmed the original structure of the DDI-C, consisting of 9 factors explained by four second-order factors: Physical and psychological punishment, response cost, inductive discipline and supervision. Mothers used significantly more than fathers all types of discipline, and boys were the focus of more discipline acts than girls. Finally, fathers showed a higher implication in the discipline of sons than
