Dynamic Effects of Communication in Software Development Teams : A Comparison of Three Models

Communication is essential to the performance of software development teams. But assuming the effect of communication on team performance to be linearly positive has been questioned in the literature. Based on team development theory and team cognition theory, this study contends that the effect of communication is dynamic and contingent on team progress. To assess the dynamic effects of communication, a longitudinal study was conducted of 73 student software development teams. Three models of communication were tested: linear model, time model, and team cognition model. The results revealed that different communication methods (emails, calls, and meetings) presented systematically changing effects on team performance as team progressed. The frequencies of emails and meetings presented increasing effects, while the frequency of telephone calls presented a decreasing effect, on team performance with time passage and the development of team cognition. An optimal model emerged from the testing results. Implications for systems development researchers and practitioners are also discussed.
A general analytical solution for groundwater fluctuations due to dual tide in long but narrow islands

This paper develops a general mathematical model for describing head fluctuations in an aquifer of long but narrow islands subject to a dual tide effect. The upper boundary condition of the aquifer is represented by an equation combining the simplified free surface equation with a leakage term. Such an equation is considered as a general expression representing the upper boundary condition of a confined, unconfined, or leaky confined aquifer. The closed‐form solution of the model represented by two series terms is developed by the direct Fourier method and finite Fourier sine transform. One of the series can reduce to a closed‐form expression by means of contour integral and residue theorem. If the width of the island is very large, this solution gives the predicted head almost the same as that of the solution for an aquifer subject to a single tide effect. It is found that the presence of an upper aquitard produces significant vertical flow in the lower leaky confined aquifer even if the aquitard permeability is low. Neglecting such vertical flow may result in an overestimate of hydraulic head in the leaky confined aquifer. The attenuation factor and phase lag predicted from the present solution subject to the dual tide effect agree well with those estimated from 57 day head fluctuation data observed at Garden Island, Australia.
Immune responses of Indian Jungle Bush Quail, P. asiatica, to different photoperiodic regimens during the reproductively inactive phase

Effects of different photoperiod regimens: Natural Day Length (NDL), Constant Light (LL), Constant Dark (DD), 16 h Light:8 h Dark (16L:8D), 14 h Light:10 h Dark (14L:10D), 12 h Light:12 h Dark (12L:12D) on immunity was noted during the reproductively inactive phase of a tropical bird, Perdicula asiatica. Extreme exposure of photoperiod i.e. LL and DD has a drastic effect on the immune status of the birds while two long photoperiods 16L:8D and 14L:10D have a significant effect when compared with the immune status of NDL birds. The immune status and melatonin level had a direct relationship but shared an inverse relationship with that of the gonadal activity of the birds. Thus, even in the tropical zone (where the photoperiod is having slight difference) the immunity relies on photoperiodic time measurement mechanisms that include the pineal gland and melatonin to relay photoperiodic changes in physiological and behavioural components of immune function.
Diffraction-limited bispectrum speckle interferometry of the nuclear region of the Seyfert galaxy NGC 1068 in the H and K' bands

We present near-infrared bispectrum speckle interferometry studies of the nuclear region of the Seyfert 2 galaxy NGC 1068. A diffraction-limited K � -band image with 74 mas resolution and the first H-band image with 57 mas resolution were reconstructed from speckle interferograms obtained with the SAO 6 m telescope. The resolved structure consists of a compact core and an extended northern and south-eastern component. The compact core is resolved at all position angles and has a north-western, tail-shaped extension as well as a fainter, south-eastern extension. The K � -band FWHM diameter of this compact core is approximately 18 × 39 mas or 1.3 × 2.8 pc (FWHM of a single-component Gaussian fit; fit range 30-80% of the telescope cut-off frequency; the diameter errors are ±4 mas), and the position angle (PA) of the north-western extension is -16 ± 4 ◦ . If 40% of the flux from the compact Kcore is emission from a point source and 60% from a Gaussian intensity distribution, then a slightly larger FWHM of approximately 26 × 58 mas is obtained for the compact Kcomponent. In the H band, the FWHM diameter of the compact core is approximately 18 × 45 mas (±4 mas), and the PA is -18 ± 4 ◦ . The extended northern component (PA ∼ 0 ◦ ) has an elongated structure with a length of about 400 mas or 29 pc. The extended south-eastern component is fainter than the northern component. The K � -a ndH-band fluxes from the resolved compact core were measured to be 350 ± 90 mJy (i.e., K � ∼ 8.2 m ) and 70 ± 20 mJy (H ∼ 10.4 m ), respectively. The PA of -16 ± 4 ◦ of the compact 18 × 39 mas core is very similar to that of the western wall (PA ∼ -15 ◦ ) of the bright region of the ionization cone. This suggests that the H- and K � -band emission from the compact core is both thermal emission and scattered light from dust near the western wall of a low-density, conical cavity or from the innermost region of a parsec-scale dusty torus that is heated by the central source (the dust sublimation radius of NGC 1068 is approximately 0.1-1 pc). The northern extended 400 mas structure lies near the western wall of the ionization cone and coincides with the inner radio jet (PA ∼ 11 ◦ ). The large distance from the core suggests that the K � -band emission of the northern extended component is scattered light from the western cavity region and the radio jet region.
Not-For-Profit Service Organizations A Cross-Sector Comparison of Motivation-Related Concepts in For-Profit

This contribution examines differences in four motivation-related concepts between employees in not-for-profit and for-profit sector service organizations. Using regression analyses, 630 knowledge workers, employed in either the not-for-profit or the for-profit sector, were compared. The majority of the hypotheses were supported by the data. Even after the impact of gender, age, seniority, contract type, and task characteristics were controlled for, employees from both sectors differed significantly. Not-for-profit workers valued more social service, perceived a better person–organization fit, and were more motivated by identified and integrated regulation. Their for-profit counterparts valued more advancement and were more motivated by external regulation. These conclusions account for a broad range of activities within the service industry because a wide variety of organizations were included in the study.
News Shocks and Labour Market Dynamics in Matching Models

We enrich a baseline real business cycle (RBC) model with search and matching frictions on the labour market and real frictions that are helpful in accounting for the response of macroeconomic aggregates to shocks. The analysis allows shocks to have an unanticipated and a news (i.e., anticipated) component. The Bayesian estimation of the model reveals that the model that includes news shocks on macroeconomic aggregates produces a remarkable fit of the data. News shocks in stationary and non-stationary TFP, investment-specific productivity and preference shocks significantly affect labour market variables and explain a sizeable fraction of macroeconomic fluctuations at medium- and long-run horizons. Historically, news shocks have played a relevant role for output, but they have had a limited influence on unemployment.
Speculations on the Consequences and Causes of Plate Motions *

Plate theory has successfully related sea floor spreading to the focal mechanisms of earthquakes and the deep structure of island arcs. It is used here to calculate the temperature distribution in the lithosphere thrust beneath island arcs, and to determine the flow and the stress elsewhere in the mantle. Comparison with observations demonstrates that earthquakes are restricted to those regions of the mantle which are colder than a definite temperature. The flow and the stress heating in the mantle can maintain the high heat flow anomaly observed behind island arcs. Plate theory also suggests a new approach to the convection problem. The most obvious mechanism causing surface motion is the force on the plates due to the sinking lithosphere. This does not appear to be the way in which the motions are maintained. However, the input of large volumes of cold material can control convection and cause general downward movements in the mantle near island arcs. This input of cold lithosphere must cease when the island arc tries to consume a continent, since the light continental crust cannot sink through the denser mantle. Attempts to assimilate continental crust in this way can produce fold mountains, and also permit a rearrangement of convection cells.
Theoretical calculation of energy levels of Pb III

In this paper, the results of theoretical calculation of five Rydberg series energy levels 5d3/2 → np1/2(n=6–20), 5d3/2 → n f5/2(n=5–20), 5d5/2 → np3/2(n=6–20), 5d5/2 → n f7/2(n=5-20) and 5d5/2 → n f5/2(n=5-20) for Pb III ions are presented using the weakest bound electron potential model (WBEPM) theory, considering foreign level perturbation corrections. The theoretically calculated results agree very well with present known experimental data, and some energy levels without experimental values are predicted.
Second International Conference on Forest Measurements and Quantitative Methods and Management & The 2004 Southern Mensurationists Meeting

AbstractSite-index ideas are reviewed, stressing conceptual foundations and issues that are fre-quently misunderstood. The structure of site-index models is explained ﬁrst within atraditional deterministic context. When variability due to environmental ﬂuctuationsand observational errors is introduced, it is found that diﬃculties of procedure andinterpretation appear. Overlooked diﬀerences in the deﬁnitions of site index implic-itly used by various authors can cause confusion. The relationship between growthfunctions and diﬀerential equations is also examined. Rational parameter estimationrequires a clear model for the error structure, and a general formulation is oﬀered. The article ends with a brief review of several site modelling methods in terms of theconcepts previously exposed. 1 Introduction Site-index models relate height, age and site quality (potential productivity) in even-agedsingle-species stands. They are used for predicting stand height development, and for assessingsite quality. Various approaches are described in textbooks such as Belyea (1931), Spurr (1952),Clutter et al. (1983), and general reviews have been published by Jones (1969), Carmean (1975),Ha¨gglund (1981), Ortega and Montero (1988), Grey (1989). In a deterministic setting, the ideas are relatively straightforward. However, when variabilitydue to weather conditions and to sampling and/or measurement error is introduced, subtle pitfallshave caused confusion and controversy. Stochastic aspects are also important in devising andevaluating estimation procedures. What follows is an exposition of key issues, focusing on generalconcepts and estimation strategies.

Mangrove sedimentary characteristics and implications for crab Ucides cordatus (Crustacea, Decapoda, Ucididae) distribution in an estuarine area of the Amazonian region

At the coastal zone sediments, water and organisms interact intensely. At equatorial tidal-dominated coast mangroves are abundant. These areas are well-known for their ecological importance. Considering the mangroves of Atlantic South America, the mangrove crab, Ucides cordatus has ecological and economic prominence. High densities of this crab are found on the Amazon coast. This study investigates the sediment distribution of the Braganca mangrove area (Amazon coast, Brazil) and its correlations with vegetation and mangrove crab distribution. Sediments of 47 sites, as well as crabs from sites with different sediment and vegetation, were sampled. Results show that surface sediment of the area is mainly composed by silt (59%), with 21% sand and 20% clay. Variations in sorting and skewness are the product of local variations in clay and sand content. The vegetation type was significantly correlated to mangrove crab characteristics, abundance and weight/size. Sediment characteristics are also substantially different according to the vegetation type. Areas where Avicennia germinans prevails have more sand and clay than areas of Rizophora mangle, in which silt is dominant and crabs were significantly heavier. The present results have showed that the distribution of sediments, crabs and vegetation at mangrove areas are strongly correlated. Thus, they should be studied in conjunction.

Pattern of acute poisoning in children in a tertiary care hospital in eastern Nepal

Background: Acute poisoning in children is a major preventable cause of morbidity and mortality. The purpose of this study is to analyze the current pattern of acute poisoning in children. Methods: This study was a retrospective hospital based analysis of data in children with acute poisoning admitted from January 2013 to December 2013. The demographic profile and outcome were recorded and analyzed. Results: A total number of 64 children (36 males & 28 females) were admitted with acute poisoning. It constituted 3.4% of the total admissions and 4.4% of the total deaths. The maximum number of children 25 (39.1%) was of the age group 1 to 5 years. Fifty-one (79.7%) were admitted in Ward and 13 (20.3%) in Pediatric Intensive Care Unit (PICU) among which 4 (6.25%) patients were put in mechanical ventilation. The most common poison involved was organophosphorus compounds 24 (37.5%) followed by mushroom 16 (25%) and kerosene 11 (17.2%). Mean time interval between ingestion and admission to hospital was 6.87 ±8.33 hours. The majority of the poisoning 28 (44%) occurred between 2pm to 7 pm. Forty-nine (76.6%) of the poisonings were non-intentional and 14 (21.6%) were intentional. Average duration of hospital stay was 4.14±1.94 days and vomiting was the commonest clinical manifestation. Of all the patients, 28 (43.8%) received pre-referral treatment, 44 (68.8%) antidotes and 22 (34.4%) gastric lavage. Conclusions: In our study, most of the poisoning was non-intentional and 1 to 5 years old children were at greater risk for poisoning. The main substance was organophosphorus.
Consumer Ethnocentrism and Its Antecedents: An Exploratory Study of Consumers in India

With dismantling of trade barriers as part of liberalisation and globalisation processes initiated during the last two decades, it is no longer a daunting task for the foreign firms to make an entry into international markets. However, what still continues to remain a major challenge is gaining consumer acceptance of foreign products. International marketing literature posits consumer ethnocentrism as a key factor affecting adversely consumer evaluation and purchase of foreign products. Present study is an attempt to investigate consumer ethnocentrism and its antecedents in the Indian context. Though the surveyed consumers in overall terms are found to be only moderately ethnocentric, significant differences are discernible in their ethnocentric tendency across socio-psychological and demographic characteristics. Based on study findings, the paper spells out strategy implications to the international marketers in gaining acceptance of their products among different consumer segments and provides directions for future researches.
An analytical model for vibration and control of a PR-PRP parallel robot with flexible platform and prismatic joint

An analytical solution for vibration of a parallel robot where its end-effector is flexible and has a passive prismatic joint(s) has not been presented before. In this research vibration analysis of a PR-PRP parallel robot using an analytical method is investigated. The PR-PRP parallel robot has two planar degrees of freedom and moves by means of two active prismatic joints. The robot moving platform is a flexible link with one passive revolute and one passive prismatic joint. First, the motion equation for a flexible link with the passive prismatic joint is developed. The motion equation is solved by employing an approximate analytical method called “constrained assumed modes method”. A time-variant constraint is written for the passive prismatic joint. The developed model allows for inclusion of the effect of physical length for the passive prismatic joint in contact with the moving platform on the vibration response of the system. For verification of the presented model and solution, three case studies are presented and results of the analytical solution are compared with results of a commercial finite element method software. For each case study, two different lengths for the passive prismatic joint are considered. Finally, active vibration control is performed for an applicable motion of the robot using the proportional-integral-derivative controller.
Production of grain legume crops alternative to soya bean and their use in organic dairy production.

This work evaluates the possibility to substitute external soya bean, a high risk GMO alimentary source, with other legumes produced on farm, such as sweet lupin, protein pea and field bean, as alternative protein source in the formulation of diet in organic dairy cattle nutrition. In 2005/2007 periods both the field and feeding trials were carried out in an organic dairy farm in Tuscany. The performances of grain legumes crops were evaluated in terms of grain yield and quality of grains. The alimentary experiment was carried out on dairy cattle fed with two diets: A with extruded soya bean and B with bitter lupin + field bean + high protein pea. In the field trial the Italian sweet lupin varieties (Multitalia) were the most interesting for CP production and pea the best for yield. The feeding trial provided that the protein content was higher for the A diet (with soya bean) while fat, somatic cells and urea content did not differ.
Probing cosmology with weak lensing selected clusters – I. Halo approach and all-sky simulations

We explore a variety of statistics of clusters selected with cosmic shear measurement by utilizing both analytic models and large numerical simulations. We rst develop a halo model to predict the abundance and the clustering of weak lensing selected clusters. Observational eects such as galaxy shape noise are included in our model. We then generate realistic mock weak lensing catalogs to test the accuracy of our analytic model. To this end, we perform full-sky ray-tracing simulations that allow us to have multiple realizations of a large continuous area. We model the masked regions on the sky using the actual positions of bright stars, and generate 200 mock weak lensing catalogs with sky coverage of 1000 squared degrees. We show that our theoretical model agrees well with the ensemble average of statistics and their covariances calculated directly from the mock catalogues. With a typical selection threshold, ignoring shape noise correction causes overestimation of the clustering of weak lensing selected clusters with a level of about 10%, and shape noise correction boosts the cluster abundance by a factor of a few. We calculate the cross-covariances using the halo model with accounting for the eective reduction of the survey area due to masks. The covariance of the cosmic shear auto power spectrum is aected by the mode-coupling eect that originates from sky masking. Our model and the results can be readily used for cosmological analysis with ongoing and future weak lensing surveys.
SMAS: A solution-based multi-agent system for improving problem solving skills in computer programming

In this research, a solution-based multi-agent system (SMAS) is proposed, which benefits from a novel automatic textto-flowchart conversion approach in order to improve students’ problem solving skills. The aim is to introduce the early stages of learning programming (CS1). By using SMAS, students can focus on solution designing activities in the form of flowchart development more than on language and syntax. Ultimately, an experimental study is devised to assess the success of SMAS as a tool to aid students with problem solving activities and learning computer programming. In total, 30.4% of problems that were left unresolved in previous sessions were solved by students in the control group, whereas 69.7% of previously unresolved problems were solved by students in the experimental group who used SMAS. Therefore, the use of SMAS in practice is supported, as the results indicate considerable gains for the experimental group over the control group.
Preincubation of Rhizobium leguminosarum bv. phaseoli with jasmonate and genistein signal molecules increases bean (Phaseolus vulgaris L.) nodulation, nitrogen fixation and biomass production.

The objective of this research work was to study the effect of Rhizobium leguminosarum pre-induced with genistein (G) and methyl jasmonate (MJ) on nodulation, nitrogen fixation and early growth of the common bean (Phaseolus vulgaris L.). Four day-old seedlings were transferred to pots, containing sterilized sand and turface (2:1 v:v) mixture and, receiving Hoagland’s nutrient solution, without nitrogen. The plants were grown in a growth chamber using a randomized complete block design with six replications. The rhizobia were cultured in TY medium and incubated with G, and/or MJ. The incubated rhizobia were used after 24 hours to inoculate the bean seedlings. The results showed that both G and MJ enhanced the nodule number, nitrogen content per plant, and plant dry matter. Genistein and MJ, when applied together to cultures, showed synergistic effects on all the characters studied. The results of this study indicated that MJ alone, or in combination with G, can be used to promote bean nodulation, nitrogen fixation and early plant growth.
