Cloudy forecast: an exploration of the factors underlying shared repository use

Many teams are now adopting shared repositories for their work. Such adoption is paradoxical, however, as past research has repeatedly shown major co-organizational barriers; teams cannot agree a common organizational scheme, making it difficult to retrieve information organized by others. Another barrier is email competition; email provides a reliable alternative for distributing files that are then personally organized. To address this paradox, we explored how 27 participants actively using shared repositories overcome these barriers in a qualitative study. We found teams addressed co-organization using 4 strategies. First they create ContentMaps that provide explicit structure to organize shared information. Participants also co-organize using implicit strategies based on task structure, expertise, and tool affordances. Greater shared repository use also leads to a changed role for email. Versioning problems mean email is not used for distributing attachments, instead for task management. We present technical implications suggesting how new tools might be better integrated with email facilitating these continued email uses.
Do the Acute Biochemical and Neuromuscular Responses Justify the Classification of Strength- and Hypertrophy-Type Resistance Exercise?

Abstract Nicholson, G, Mcloughlin, G, Bissas, A, and Ispoglou, T. Do the acute biochemical and neuromuscular responses justify the classification of strength- and hypertrophy-type resistance exercise? J Strength Cond Res 28(11): 3188–3199, 2014—This study aimed to examine a wide profile of acute biochemical and neuromuscular responses to strength (STR) and hypertrophy (HYP) resistance exercise (RE). Seven trained men completed an STR workout (4 × 6 repetitions, 85% 1 repetition maximum [1RM], 5-minute rest periods), an HYP workout (4 × 10 repetitions, 70% 1RM, 90-second rest periods), and a control condition (CON) in a randomized crossover design. Peak force (PF), rate of force development (RFD), and muscle activity were quantified before and after exercise during an isometric squat protocol. Blood samples were taken 20, 10, and 0 minutes before and 0, 10, and 60 minutes after exercise to measure the concentration of blood lactate (BL), pH, and a number of electrolytes that were corrected for plasma volume changes. No differences were observed between the workouts for changes in PF, RFD, or muscle activity. Repeated contrasts revealed a greater (p ⩽ 0.05) increase in BL concentration and reduction in pH after the HYP protocol than the STR or CON conditions. There were similar but significant (p ⩽ 0.05) changes in the concentration of a number of electrolytes after both workouts, and a handful of these changes displayed significant correlations with the PF reductions observed after the HYP condition. Although the STR and HYP workouts were significantly different in terms of intensity, volume, and rest, these differences were only observable in the acid-base responses. The present findings reinforce the need for practitioners to look beyond the classification of RE workouts when aiming to elicit specific physiological responses.

Design and analysis of CPW-fed quasi-self-complementary pentagonal antenna for ultra-wideband systems

Design and performance of a coplanar-waveguide (CPW) fed quasi-self-complementary pentagonal antenna (QSCPA) for ultra-wideband systems is presented and analyzed in this paper. The proposed antenna is designed on RO3003 dielectric material with relative permittivity of 3 and thickness of 1.52 mm. Predicted impedance bandwidth of the proposed antenna is 2.77-11.84 GHz, for VSWR <; 2, which covers the whole ultra-wideband (3.1-10.6 GHz). The performance of the antenna for various parameters is investigated and meticulously presented. The optimal designed antenna provides a gain variation within 1 dBi and a satisfactory radiation patterns at different resonant frequencies in the operating bandwidth. The antenna is highly efficient with 87% average radiation efficiency. The proposed antenna provides a flexible environment which makes it favorable for integrating with body-centric wireless communication devices.
The Neuroscience of Maternal Love

Maternal love, which is at the core of maternal behavior, is essential for the mother–infant attachment relationship and is important for an infant’s development and mental health. In addition, maternal love plays important roles in promoting not only the infant’s resilience, but also the mother’s. Therefore, it is crucial to clarify the neural basis of maternal love and related behaviors to understand both normal mothering and abusive and neglectful mothering. Here, we have reviewed our recent neuroimaging studies on the neural basis of maternal love and behavior. Based on the assumption that a mother’s love for her infant is invariant in any situation, we found that a limited number of the mother’s brain areas were specifically involved in maternal love, namely, the orbitofrontal cortex (OFC), striatum, anterior insula, and periaqueductal gray, suggesting that maternal love is mediated via integration of the two major neural systems in the OFC: the dopamine reward system (the OFC and striatum) and the interoceptive information processing system (the OFC, insula, and periaqueductal gray). Additionally, when the mother viewed her own infant in distress, there was significant activation in the dorsal OFC, dorsolateral prefrontal cortex, ventrolateral prefrontal cortex, dorsomedial prefrontal cortex, dorsal anterior cingulate cortex, posterior cingulate cortex, caudate nucleus, supplementary motor area, and posterior superior temporal sulcus/temporoparietal junction. These results suggest that a highly elaborate neural mechanism, based on the neural basis of maternal love, mediates the diverse and complex maternal behaviors that mothers engage in when raising and protecting their own infants.
Labor reallocation, Productivity and Output Volatility in Japan

Title of dissertation: LABOR REALLOCATION, PRODUCTIVITY AND OUTPUT VOLATILITY IN JAPAN Naomi N. Griffin, Doctor of Philosophy, 2005 Dissertation directed by: Professor John Haltiwanger Department of Economics The dissertation offers an analysis of the labor reallocation process in Japan and sheds light on its relationship with productivity and output volatility during the 1990s, the period of sluggish growth. The first chapter provides descriptive statistics of job reallocation rates among relatively large Japanese firms. The main results show that job reallocation follows a steady decline in volatility between 1967 and 1997 and exhibits little deviation from its long-run trend in the 1990s. At the same time, the idiosyncratic effects of job reallocation appear to counteract the sectoral/aggregate effects during the 1990s in the manufacturing sector. Finally, the contribution of net entry to overall productivity growth has decreased during this period, mainly through exits by relatively productive firms. The second chapter investigates the labor input and inventory responses to demand shocks in both the Japanese manufacturing sector as a whole, and the Iron and Steel industry. The main results show that first, demand shocks increased in volatility after 1992 in both the manufacturing sector and the Iron and Steel industry. Second, for the manufacturing sector, the adjustment mechanism shifted from an intensive use of inventories to more of a reliance on employment and work hours after 1992. Finally, for the Iron and Steel industry, the employment and inventory adjustments do not exhibit any systematic changes while the work hour adjustment has become more intense since 1992. The third chapter provides a theoretical examination of the impact of the Employment Adjustment Subsidy (EAS). A partial equilibrium industry model with heterogeneous establishments and aggregate uncertainty shows that the EAS lowers labor productivity, while reducing job flows and increasing average firm-level employment. While the directly measured impact on productivity is proportional to the fraction of subsidized workers, the indirect effects of the subsidy on output and employment volatility can be substantially larger. The subsidy can lead to a sizable increase in output fluctuations over the business cycle by symmetrically increasing the output response to shocks, while still meeting its primary objective of reduced employment volatility.

The colours of satellite galaxies in groups and clusters

Current models of galaxy formation predict satellite galaxies in groups and clusters that are redder than observed. We investigate the effect on the colours of satellite galaxies produced by the ram-pressure stripping of their hot-gaseous atmospheres as the satellites orbit within their parent halo. We incorporate a model of the stripping process based on detailed hydrodynamic simulations within the Durham semi-analytic model of galaxy formation. The simulations show that the environment in groups and clusters is less aggressive than previously assumed. The main uncertainty in the model is the treatment of gas expelled by supernovae. With reasonable assumptions for the stripping of this material, we find that satellite galaxies are able to retain a significant fraction of their hot gas for several Gyr, thereby replenishing their reservoirs of cold, star-forming gas and remaining blue for a relatively long period of time. A bimodal distribution of galaxy colours, similar to that observed in Sloan Digital Sky Survey data, is established and the colours of the satellite galaxies are in good agreement with the data. In addition, our model naturally accounts for the observed dependence of satellite colours on environment, from small groups to high-mass clusters.
Creatine supplementation does not affect kidney function in an animal model with pre-existing renal failure.

BACKGROUND Creatine is widely used as an ergogenic substance among athletes. Safety of prolonged creatine intake has been questioned, based upon case reports and animal data. We investigated the effect of prolonged creatine ingestion on renal function in animals with normal kidney function or pre-existing kidney failure, respectively. METHODS Male Wistar rats were randomly allocated to four experimental groups: (i) sham-operated, control diet; (ii) sham-operated, creatine-supplemented diet (2% w/w (0.9+/-0.2 g creatine/kg body weight/day)); (iii) two-thirds nephrectomized, control diet; and (iv) two-thirds nephrectomized, creatine supplemented diet. Glomerular filtration rate was determined using inulin and creatinine clearance, together with albumin excretion, urea clearance, muscle and serum creatine and serum cystatin C concentrations. RESULTS In contrast to previous reports, no detrimental effects of creatine supplementation on the renal function indices were observed in two-thirds nephrectomized or sham-operated animals. No differences were observed in inulin (0.28+/-0.08 vs 0.25+/-0.08 ml/min/100 g; P=NS) or creatinine clearance rates. Serum cystatin C concentration, urinary protein excretion, and albumin and urea clearance were comparable between creatine-supplemented and control-diet fed animals in both sham-operated and two-thirds nephrectomized animals. Serum creatine and intramuscular total creatine concentrations were higher in creatine-supplemented groups (P<0.05). CONCLUSIONS Creatine supplementation at a dosage of 2% w/w for 4 weeks does not impair kidney function in animals with pre-existing renal failure or in control animals.
Smart: a MapReduce-like framework for in-situ scientific analytics

In-situ analytics has lately been shown to be an effective approach to reduce both I/O and storage costs for scientific analytics. Developing an efficient in-situ implementation, however, involves many challenges, including parallelization, data movement or sharing, and resource allocation. Based on the premise that MapReduce can be an appropriate API for specifying scientific analytics applications, we present a novel MapReduce-like framework that supports efficient in-situ scientific analytics, and address several challenges that arise in applying the MapReduce idea for in-situ processing. Specifically, our implementation can load simulated data directly from distributed memory, and it uses a modified API that helps meet the strict memory constraints of in-situ analytics. The framework is designed so that analytics can be launched from the parallel code region of a simulation program. We have developed both time sharing and space sharing modes for maximizing the performance in different scenarios, with the former even avoiding any copying of data from simulation to the analytics program. We demonstrate the functionality, efficiency, and scalability of our system, by using different simulation and analytics programs, executed on clusters with multi-core and many-core nodes.
Mutational analysis of the interaction between the bovine papillomavirus E5 transforming protein and the endogenous beta receptor for platelet-derived growth factor in mouse C127 cells

The bovine papillomavirus E5 protein is a 44-amino-acid membrane-associated protein that forms a stable complex with the endogenous platelet-derived growth factor (PDGF) beta receptor in rodent and bovine fibroblasts, resulting in sustained receptor activation and cell transformation. We report here that high-level expression of the E5 protein caused a reduction in the level of the mature form of the PDGF beta receptor in acutely and stably transformed mouse C127 cells. To explore in more detail the interaction of the E5 protein and the PDGF beta receptor, we tested the abilities of various E5 point mutants to bind the PDGF receptor, to induce PDGF receptor down-regulation and tyrosine phosphorylation, and to transform cells. A transformation-competent mutant, like the wild-type E5 protein, bound the receptor and induced receptor tyrosine phosphorylation and down-regulation. Transformation-defective E5 proteins either failed to interact with the endogenous PDGF beta receptor in mouse fibroblasts or underwent an aberrant interaction with the receptor. Mutation of glutamine at position 17, aspartic acid at position 33, or both carboxyl-terminal cysteine residues required for E5 homodimerization interfered with stable complex formation with the PDGF receptor, tyrosine phosphorylation and down-regulation of the receptor, and cell transformation. Point mutations at several other carboxyl-terminal positions generated transformation-defective E5 proteins that formed a complex with the PDGF receptor and induced receptor tyrosine phosphorylation but did not induce PDGF receptor down-regulation. Either PDGF receptor activation is not sufficient for transformation of C127 cells or the receptors that are tyrosine phosphorylated in response to these mutant E5 proteins are not fully activated and therefore are not able to deliver a mitogenic signal.
ON THE FEEDBACK EFFICIENCY OF ACTIVE GALACTIC NUCLEI

We measure and analyze the energy, momentum, and mass feedback efficiencies due to radiation from active galactic nuclei (AGNs) in relatively large-scale outflows (from ∼0.01 to ∼10 pc). Our measurements are based on the two-dimensional (axisymmetric) and time-dependent radiation–hydrodynamical simulations recently presented in Kurosawa & Proga. In that paper, we studied outflows from a slowly rotating (sub-Keplerian) infalling gas driven by the energy and pressure of the radiation emitted by the AGNs. These simulations follow the dynamics of gas under the influence of the gravity of the central 108 M☉ black hole (BH) on scales from ∼0.01 to ∼10 pc. They self-consistently couple the accretion luminosity with the mass inflow rate at the smallest radius (our proxy for the mass-accretion rate, ). Over 30 simulations have been performed to investigate how the results depend on the gas density at the outer radius, ρo. A key feature of these simulations is that the radiation field and consequently the gas dynamics are axisymmetric, but not spherically symmetric. Therefore, the gas inflow and outflow can occur at the same time. We compare our –ρo relation with that predicted by the Bondi accretion model. For high luminosities comparable to the Eddington limit, the power-law fit to our models yields q ≈ 0.5 instead of q = 1.0, which is predicted by the Bondi model. This difference is caused by the outflows which are important for the overall mass budget at high luminosities. The maximum momentum and mass feedback efficiencies found in our models are ∼10−2 and ∼10−1, respectively. However, the outflows are much less important energetically: the thermal and kinetic powers in units of the radiative luminosity are ∼10−5 and ∼10−4, respectively. In addition, the efficiencies do not increase monotonically with the accretion luminosity but rather peak around the Eddington limit beyond which a steady-state disk–wind-like solution exists. Our energy feedback efficiencies are significantly lower than 0.05, which is required in some cosmological and galaxy merger simulations. The low feedback efficiencies found here could have significant implications on the mass growth of super massive BHs in the early universe. We stress, however, that we have not considered the innermost parts of the accretion and outflow where radiation and matter interact most strongly. The feedback from this region could have efficiencies significantly above the low values found here.
Measuring the Effects of Economic Diversity on Growth and Stability

The role of economic diversity in regional stability and growth is examined. Contrary to "conventional wisdom" the empirical literature has been unable to confirm the link between diversity and economic performance. Traditional notions of diversity tend to be defined narrowly, usually emphasizing the distribution of employment across industries. These approaches are inadequate because they do not capture elements of inter-industrial linkages. An alternate approach to conceptualizing diversity, based on a regional input-output model, is described and computed for the 50 states. Empirical results suggest that diversity within the theoretical construct of input-output is associated with higher levels of stability and growth.
The Impact of Preferential Trade Agreements on Import Flows

This paper examines the preferential trade agreements’ (PTAs) effects on import flows. In previous studies, standard gravity models based on ordinary least squares (OLS) are applied in order to study the effects of PTAs participation. However, the use of this traditional method leads to an increased risk of so-called self-selection bias. That is, the countries that enter PTAs are non-randomized, which implies that these countries possess different features compared to other, often weaker, countries. In contrast to previous studies, I apply a matching technique which is able to address this selection bias, heterogeneity, and is more robust to solve the misspecification bias. Thus, despite that this remedial so-called propensity-score matching technique is utilized to filter out the problems of self-selection, we still come to the main conclusion that PTAs participation seems to increase the nations’ import flows.
Earnings Differential Between Male-Female In Indonesia: Evidence From Sakernas Data

This Research aims to analyze the earnings inequality in Indonesia and to know whether the earnings inequality can be explained by individual characteristic factors such as education and experience; location both urban-rural and province where individual reside and work; and based on socio-demography-economic characteristic. Furthermore, this research tries to know how big those factors contribute to the existing inequality, before and after crisis. Using data from SAKERNAS 1996, 1999, 2002, and 2004, the valid observation is about 145660 individual. Result of analysis clearly indicate that there are significant gender inequalities in earnings in Indonesia, based on education and experience; urban-rural location and province where individual reside and work and based on socio-demography-economic characteristic. The profile of earnings inequality by gender seems to be an “inverted U” fashion, with the male-female earnings gap narrowing as educational attainment went up, and reached a plateau at the “post-secondary level” and then tapered off. The analysis also suggests that the industrial affiliation of female workers matter.The result of estimating Mincerian earnings equation shows that such factor as human capital (years of schooling and experience); socio-demography-economic characteristic (being household’s head, gender, marriage status, work sector); and location factors (urban-rural and province which individual reside and work), significantly affects individual earning in Indonesia. Meanwhile, the result of decomposing this earnings inequality indicate that factor causing earnings inequality between “male” and “female” is about 41.6 percent caused by endowment differences. On the other hand, most of the gap about 58.4 percent attributed to unobserved and unexplained factors, rather than attributed to differences in observable endowments.
How Does Project Termination Impact Project Team Members? Rapid Termination, ‘Creeping Death’, and Learning from Failure

Although extant studies have increased our understanding of the decision of when to terminate a project and its organizational implications, they do not explore the contextual mechanisms underlying the link between the speed at which a project is terminated and the learning of those directly working on the project. This is surprising because perceptions of project failure likely differ between those who own the option (i.e., the decision maker) and those who are the option (i.e., project team members). In this multiple case study, we explored research and development (RD (2) rather than obstructing learning from project experience, negative emotions motivated sensemaking efforts; and (3) rather than emphasizing learning after project termination, in the context of rapid redeployment of team members after project termination, delayed termination provided employees the time to reflect on, articulate, and codify lessons learned. We discuss the implications of these findings.
Optimal control of service rates in networks of queues

We prove a monotonicity result for the problem of optimal service rate control in certain queueing networks. Consider, as an illustrative example, a number of ·/M/1 queues which are arranged in a cycle with some number of customers moving around the cycle. A holding cost hi (xi ) is charged for each unit of time that queue i contains xi customers, with hi being convex. As a function of the queue lengths the service rate at each queue i is to be chosen in the interval , where cost ci (μ) is charged for each unit of time that the service rate μis in effect at queue i. It is shown that the policy which minimizes the expected total discounted cost has a monotone structure: namely, that by moving one customer from queue i to the following queue, the optimal service rate in queue i is not increased and the optimal service rates elsewhere are not decreased. We prove a similar result for problems of optimal arrival rate and service rate control in general queueing networks. The results are extended to an average-cost measure, and an example is included to show that in general the assumption of convex holding costs may not be relaxed. A further example shows that the optimal policy may not be monotone unless the choice of possible service rates at each queue includes 0.
