Chemical and mineral compositions of pods of Moringa stenopetala and Moringa oleifera cultivated in the lowland of Gamogofa Zone

This study was conducted to evaluate the chemical and mineral compositions of whole and seeds-removed fresh pods of Moringa stenopetala and Moringa oleifera. Feed samples were collected from five trees of each Moringa species and analyzed for nutrients using standard methods. The results indicated that whole fresh pods of both Moringa species contained high crude protein (CP), fat and gross energy (GE) values. The highest CP (182 g/kg DM) was obtained from whole fresh pods of M. stenopetala while the lowest in seeds-removed fresh pods of M. oleifera (104 g/kg DM). The GE content (17.3-18.0 MJ/kg DM) was similar across pod parts except in seeds-removed fresh pods of M. stenopetala with the lowest value (16.3 MJ/kg DM). In both Moringa species, seeds-removed fresh pods contained high crude fiber, neutral detergent fiber, cellulose and hemicelluloses. In M. stenopetala, calcium content was 3.72 and 2.98 g/kg DM in whole fresh pods and seeds-removed fresh pods, respectively. In M. oleifera, whole and seeds-removed fresh pods contained 3.34 and 2.74 g/kg DM calcium, respectively. High zinc and iron concentrations were found in whole and seeds-removed fresh pods of both Moringa species, respectively. Both whole and seeds-removed fresh pods of M. oleifera had higher copper values (9.3-9.7 mg/kg DM) than those of M. stenopetala (4.8-5.8 mg/kg DM). In conclusion, the fresh pods of both Moringa species could be used as alternative energy and protein sources for feeding ruminant and monogastric animals during dry periods of the year. The fresh pods might be also useful source of macro and trace minerals in human nutrition.
Telework: Dispersed Organizational Activity and New Forms of Spatial-Temporal Co-ordination and Control

Abstract This article focuses on a set of new flexible work arrangements commonly referred to as “telework” or “telecommuting”. Although it is not possible to give an unambiguous and precise definition of telework, there is some working consensus on the subject: the belief is held that information technology has made it possible to relocate many types of work involving the electronic processing of information geographically, and telework is the term used to describe workers who have been relocated in this way. An attempt is made to develop a theoretical framework in which telework can be studied. For this purpose the changes that take place in the environment of organizations have been taken into consideration.
Work–Family Balance Among Coach-Fathers: A Qualitative Examination of Enrichment, Conflict, and Role Management Strategies

Work–family balance in sport has until this point largely been characterized as an issue for women. Current societal trends, however, suggest that men also struggle with balancing work and family responsibilities. Using theoretical frameworks from both conflict and enrichment, this study examined the ways that fathers who are coaches experience and manage the work–life interface. Twenty-four men who are fathers and high school varsity head coaches were interviewed for this study. The respondents discussed the day-to-day challenges and coping strategies they utilized to manage their work–life interface. Ultimately, five themes emerged from the data, including (a) coaching as more than an occupation, (b) experiences of conflict and strain, (c) coping strategies, (d) nonutilization of organizational supports, and (e) experiences of enrichment. These findings suggest that, indeed, men struggle with balancing competing role demands. However, the findings also suggest that men are utilizing diverse and creative.
Animated free-form deformation: an interactive animation technique

Current research efforts focus on providing interactive techniques that make 3D concepts easy to use and accessible to large numbers of people. In this paper, a new interactive technique for animating deformable objects is presented. The technique allows easy specification and control of a class of deformations that cannot be produced by existing techniques without considerable human intervention.The methodology proposed relies on the Free-Form Deformation (FFD) technique. It makes use of a deformation tool that is animated like any other object.This approach provides a representation of the deformations independent of the surface geometry, and can be easily integrated into traditional hierarchical animation systems.
Analysis of N-Block Caching Strategies

In this paper, we study the behavior of distributed cache for N-block replacement in cache replacement strategies. Distributed cache is an extension of traditional concept of cache. A distributed cache spans multiple servers, which can grow in size and transactional capacity, providing better consistency and reliability compared to in-memory caches. Traditional cache replacement strategies replace one block at a time, we study the eﬀect of replacing N blocks at a time. In this new approach to distributed cache management, we will evaluate cache replacement algorithms for hit and miss rates, memory access time, and disk access rate. In this paper, we describe the techniques used to implement cache replacement strategies for N-block replacements. Simulation and visualizations are used to show the eﬀectiveness of the proposed scheme.
AISeL ) All Sprouts Content Sprouts 12-7-2010 Evaluating the Applicability of a Use Value-Based File Retention Method

A well constructed file retention policy can help a company determine the relative value and the corresponding retrieval service level of the different files it owns. Though such a retention policy is useful, the method one can use to arrive at such a policy is under-researched. This paper discusses how one can arrive at a method (based on a systematic literature review) for developing file retention policies based on use values of files. In the case study, we demonstrate how one can develop a file retention policy by testing of causal relations between file retention policy parameters and the use value of files. This case study shows that, contrary to suggestions of previous research, the file type has no significant causal relation with the value of a file and thus should be excluded from a retention policy in this case. The case study also shows that there is a strong causal relation between the position of a user of a file and the value of this file. Furthermore, we have amended an existing subjective file valuation method, namely, the Information Value Questionnaire (IVQ). However, to make file retention methods effective and reliable a substantially more case experiences need to be collected.
Low-Energy Data Cache Using Sign Compression and Cache Line Bisection

Cache accesses consume a significant portion of total energy dissipation in modern microprocessors. In this paper, we introduce a new technique for data cache energy reduction, which exploits the prevalence of small values and the inefficiency of using a full word for their storage. Simulation results show that we can reduce total data cache energy by around 23% for the SPEC benchmarks without significant performance degradation. We also propose a modified data compression cache architecture utilizing empty cache space that is not used after data compression. This proposed architecture improves the cache miss rate, which results in improved performance and reduced energy dissipation when accessing the next level of the memory hierarchy. We show that this scheme has an energy saving of about 19%.
A radio over fiber link for the wireless distribution of 3-Gb/s uncompressed HD video (invited paper)

A radio over fiber link for the wireless distribution of 3-Gb/s uncompressed HD video is developed. The power fading caused by the dispersion of the optical fiber is effectively reduced by using a polarization modulator (PolM) in the transmitter. In the receiver, an injection-locked frequency-doubling optoelectronic oscillator (OEO) is employed to simultaneously extract the RF carrier and perform photonic microwave downconversion. The system features simple configuration, high performance and stable operation.
An entropy based method for measuring anonymity

Data holders use data masking techniques for limiting disclosure risk in releasing sensitive datasets. Disclosure risk is often expressed in terms of rareness or of probability of re-identification. We propose a novel measure of disclosure risk, based on Shannon entropy, which combines together these two approaches. This measure represents the uncertainty of the linkage of the masked record with the original dataset, and so an estimation of the disclosure risk. It is also related to the size of the support of an equivalent random process with a uniform distribution. This allows us to define for any masking transformation an effective k value in analogy to k-anonymity measure used for integrity preserving transformations. Furthermore, this measure provides a direct link to the information loss in the transformations, providing some insights about the utility. We demonstrate this approach in a toy example using a dataset masked by adding Gaussian noise.
Detecting Lasting and Abrupt Bursts in Data Streams Using Two-Layered Wavelet Tree

Real-time network and telecommunication systems often generate tremendous volume of streaming data. Effective modeling of such streaming data and detecting the bursts with single-scan algorithms pose great challenges. The aim of detecting bursts in data streams is to find anomalous aggregation in stream subsequences. We introduce Lasting Factor and Abrupt Factor in the general definition of burst, in order to characterize how a burst grows in real applications. A novel two-layered wavelet tree structure is designed to detect lasting bursts and abrupt bursts in linear time. Our algorithm reports appearance time range and average aggregate value for lasting bursts, break point position and peak value for abrupt bursts. Theoretical analysis and comparison experiments on the Internet Traffic Archive dataset verify the superiority of our approach over other burst detection algorithms in burst characterization and computation efficiency.
Network Design and Analysis Problems in Telecommunication, Location-Allocation, and Intelligent Transportation Systems

(ABSTRACT) This research is concerned with the development of algorithmic approaches for solving problems that arise in the design and analysis of telecommunication networks, location-allocation distribution contexts, and intelligent transportation networks. Specifically, the corresponding problems addressed in these areas are a local access and transport area (LATA) network design problem, the discrete equal-capacity p-median problem (PMED), and the estimation of dynamic origin-destination path flows or trip tables in a general network. For the LATA network problem, we develop a model and apply the Reformulation-Lineariz-ation Technique (RLT) to construct various enhanced tightened versions of the proposed model. We also design efficient Lagrangian dual schemes for solving the linear programming relaxation of the various enhanced models, and construct an effective heuristic procedure for deriving good quality solutions in this process. Extensive computational results are provided to demonstrate the progressive tightness resulting from the enhanced formulations and their effect on providing good quality feasible solutions. The results indicate that the proposed procedures typically yield solutions having an optimality gap of less than 2% with respect to the derived lower bound, within a reasonable effort that involves the solution of a single linear program. For the discrete equal-capacity p-median problem, we develop various valid inequalities, a separation routine for generating cutting planes via specific members of such inequalities, as well as an enhanced reformulation that constructs a partial convex hull representation that subsumes an entire class of valid inequalities via its linear programming relaxation. We also propose suitable heuristic schemes for solving this problem, based on sequentially rounding the continuous relaxation solutions obtained for the various equivalent formulations of the problem. Extensive computational results are provided to demonstrate the effectiveness of the proposed valid inequalities, enhanced formulations, and heuristic schemes. The results indicate that the proposed schemes for tightening the underlying relaxations play a significant role in enhancing the performance of both exact and heuristic solution methods for solving this class of problems. For the estimation of dynamic path flows in a general network, we propose a parametric optimization approach to estimate time-dependent path flows, or origin-destination trip tables , using available data on link traffic volumes for a general road network. Our model assumes knowledge of certain time-dependent link flow contribution factors that are a dynamic generalization of the path-link incidence matrix for the static case. We propose a column generation approach that uses a sequence of dynamic shortest path subproblems in order …
Chandra Observation of Low-Mass X-Ray Binaries in the Elliptical Galaxy M84

We present characteristics of the X-ray point-source population in the M84 galaxy observed by the Chandra Advanced CCD Imaging Spectrometer S-Array. We find an excess in the number of sources centered on M84 with a spatial distribution closely corresponding to the M84 stellar light. Given an absence of recent star formation, accreting binaries are the only candidates for the M84 X-ray sources. The majority of M84 sources (with luminosities exceeding 1038 ergs s-1) exhibit hardness ratios expected from multitemperature blackbody disk emission. The most luminous sources, which we attribute to accreting black holes, exhibit X-ray colors typical of a blackbody spectrum. We also identify the sources whose X-ray colors match the expectations for constituents of the cosmic X-ray background. The number of such sources agrees with that expected to be background sources. After correcting for incompleteness in the source detection, we find a log N- log S for M84 similar to that of the elliptical galaxy NGC 4697, i.e., having a break at a luminosity of Lb = 2.4 × 1038 ergs s-1, approximately the Eddington limit on the isotropic luminosity for accretion onto a neutron star. The slope of the luminosity function above the break provides evidence for a mass distribution in the M84 accreting black holes.
Running head : Balance strategies in clumsy children Slowed muscle force production and sensory organization deficits contribute to altered postural control strategies in children with developmental coordination disorder

This study aimed to (1) compare the postural control strategies, sensory organization of balance control, and lower limb muscle performance of children with and without developmental coordination disorder (DCD), and (2) determine the association between postural control strategies, sensory organization parameters and knee muscle performance indices among children with DCD. Fifty-eight DCD-affected children and 46 typically developing children participated in the study. Postural control strategies and sensory organization were evaluated with the Sensory Organization Test (SOT). Knee muscle strength and time to produce maximum muscle torque (at 180°/s) were assessed using an isokinetic machine. Analysis of variance was used to compare the outcome variables between groups, and multiple regression analysis was used to examine the relationships between postural control strategies, sensory organization parameters, and isokinetic indices in children with DCD. The DCD group had significantly lower strategy scores (SOT conditions 5 and 6), lower visual and vestibular ratios, and took a longer time to reach peak torque in the knee flexor muscles than the control group (p > 0.05). After accounting for age, sex, and body mass index, the vestibular ratio explained 35.8% of the variance in the strategy score of SOT condition 5 (p < 0.05). Moreover, the visual ratio, vestibular ratio, and time to peak torque of the knee flexors were all significant predictors (p < 0.05) of the strategy score during SOT condition 6, accounting for 14%, 19.7%, and 19.8% of its variance, respectively. The children 3 Running head: Balance strategies in clumsy children with DCD demonstrated deficits in postural control strategy, sensory organization and prolonged duration of muscle force development. Slowed knee muscle force production combined with poor visual and vestibular functioning may result in greater use of hip strategy by children with DCD in sensory challenging environments.
Effect of Japanese Herbal Kampo Medicine Goreisan on Reoperation Rates after Burr-Hole Surgery for Chronic Subdural Hematoma: Analysis of a National Inpatient Database

Goreisan is a herbal Kampo medicine used for treating chronic subdural hematoma (CSDH) in Japan. Experimental studies have suggested that Goreisan exerts a hydrogogue effect, but clinical evidence for the effectiveness of Goreisan in CSDH is currently lacking. Using a national Japanese inpatient database, we examined the association between Goreisan use and reoperation rates after burr-hole surgery for CSDH. We identified 36,020 patients, including 3,889 Goreisan users and 32,131 nonusers. Propensity scores of receiving Goreisan were calculated based on hospital characteristics and patient backgrounds (age, sex, body mass index, activities of daily living, consciousness level, comorbidities, antithrombotic agent use, mannitol infusion, and corticosteroid infusion). One-to-one propensity-score matching created 3,879 pairs of Goreisan users and nonusers. Propensity-matched analysis revealed that Goreisan use was significantly associated with a lower reoperation rate (4.8%) compared with nonuse (6.2%) (risk difference, −1.4%; 95% confidence interval (CI), −2.4% to −0.38%). The number needed to prevent one reoperation was 72 (95% CI, 41–265). Instrumental-variable analysis showed similar results to the propensity-matched analysis. These results suggest that Goreisan use reduced the need for reoperation after burr-hole surgery for CSDH.
Gaming Expertise: Doing Gender and Maintaining Social Relationships in the Context of Gamers’ Daily Lives

Abstract This article argues for an attempt to rethink what counts as gaming expertise. Often, expertise is configured as a fixed and measurable rather than relational capacity – having the necessary level of knowledge with a skill to become expert, or to rise above a particular and objectively defined level of competency. Drawing on interviews with women playing the massively multiplayer online game Massively multiplayer online games are games capable of supporting large numbers of players interacting, competing and cooperating, as they simultaneously inhabit the persistent open world of the game space. World of Warcraft, the article argues for an understanding of gaming expertise as a relational, highly contextual capacity, operating and embedded in everyday situations. Through the lens of gaming expertise, the article teases out the complex ways in which gender, technology and identity intersect and are constructed and negotiated in different social contexts.
Requirement of c-Jun NH2-Terminal Kinase for Ras-Initiated Tumor Formation

ABSTRACT The c-Jun NH2-terminal kinase (JNK) signal transduction pathway causes increased gene expression mediated, in part, by members of the activating transcription factor protein (AP1) group. JNK is therefore implicated in the regulation of cell growth and cancer. To test the role of JNK in Ras-induced tumor formation, we examined the effect of compound ablation of the ubiquitously expressed genes Jnk1 plus Jnk2. We report that JNK is required for Ras-induced transformation of p53-deficient primary cells in vitro. Moreover, JNK is required for lung tumor development caused by mutational activation of the endogenous KRas gene in vivo. Together, these data establish that JNK plays a key role in Ras-induced tumorigenesis.
Size and Return: A New Perspective

We document robust empirical evidence that, after controlling for idiosyncratic volatility, large stocks earn significantly higher returns than small stocks. Our empirical results indicate that idiosyncratic volatility is positively related to return, but negatively related to size. Hence, failure to control for idiosyncratic volatility generates a downward omitted variable bias and leads to the widely documented negative relation between size and return. We explain the two contrasting size-return relations, with and without the control for idiosyncratic volatility, in a parsimonious equilibrium model that incorporates three empirical regularities: some individual investors are under-diversified; small stocks have higher idiosyncratic volatilities than large stocks; and large stocks, relative to their size, are held by fewer investors than small stocks. Investors follow mean-variance optimization to allocate wealth among their stocks. To clear the markets, large stocks have to offer higher expected returns to induce their relatively smaller number of investors to allocate more of their wealth. This positive size-return relation is masked because small firms have higher idiosyncratic volatilities and therefore earn higher returns as a result of investor under-diversification.

City as Lens

In recent years, a paradox has emerged in the study of youth. On the one hand, in the context of the processes of globalization, neoliberalism and precarity, the patterning of leisure and work for young people is becoming increasingly convergent across time and space. On the other hand, it is clear that young people’s habits and dispositions remain deeply tied to local places, with global processes filtered and refracted through specific cultural contexts. Against this backdrop, drawing on an Economic and Social Research Council/Research Grants Council (ESRC/RGC)-funded study of contemporary youth in Glasgow and Hong Kong, this article seeks to explore the role of the city as a mediating lens between global forces and local impacts. Utilizing both historical and contemporary data, the article argues that despite parallels in the impact of global forces on the structure of everyday life and work, young people’s leisure habits remain rooted in the fates and fortunes of their respective cities.
