When more is more? The impact of breadth and depth of information disclosure on attributional confidence about and interpersonal attraction to a social network site profile owner

Social network sites (SNSs) provide users with ample opportunity to share information about themselves and to engage in social browsing to learn about others. This article reports results from two experiments (with participants from the U.S.) that investigate the impacts of breadth and depth of information disclosed in a profile on viewers’ attributional confidence about and interpersonal attraction to the profile owner. In the first experiment (n = 320), participants viewed a profile containing either low or high breadth of information. Analyses indicated that, higher breadth of information shared in the profile increased interpersonal attraction and that attributional confidence mediated this relationship. The second experiment (n = 537) tested the respective influences of breadth (low vs. high) and depth of disclosure (low vs. high) in a profile on perceivers’ attributional confidence and interpersonal attraction. Analyses indicated that, while increasing the breadth of information had a positive impact on interpersonal attraction to profile owners, increasing the depth of information reduced attraction. Additionally, there was a significant interaction between breadth and depth of information in predicting attributional confidence; increasing the depth of information shared in an SNS profile enhanced attributional confidence only when the breadth of information shared was low.
A new method for determining the meridional wind velocity during an ionospheric storm

This paper introduces a new method for determining the meridional wind velocity during an ionospheric storm based on a sequence of Doppler ionograms. By this new method, the height‐ and time‐dependent meridional wind velocity in the F2 layer was obtained during the magnetic substorm on April 17, 2002. The peak velocity of meridional wind at 300 km altitude is about 300 m/s, the deduced propagation velocity of traveling atmospheric disturbances (TADs) is about 520 m/s. Furthermore, not only the amplitude but also the onset time and phase velocity of the TAD‐associated wind perturbation can be explained by the present theories and observations of meridional winds. This work offers a new method to investigate the propagation and morphology of meridional wind during a magnetic substorm by using Digisonde routine observations.
INVESTIGATING THE USE OF UNCERTAINTY MANAGEMENT TOOLS AND TECHNIQUES WITHIN THE CONSTRUCTION SECTOR IN NIGERIA

This study investigated the use of uncertainty management tools within the construction sector in Nigeria. The objectives were to evaluate the level of use of uncertainty management tools and techniques and to determine the factors responsible for the low knowledge and misconception of uncertainty within the construction sector. Views from project managers obtained from two sub-sectors, the real estate and the oil and gas was evaluated. Finding of the study revealed low level of use of uncertainty management tools and techniques due to the lack of clear understanding of uncertainty and its management parameters. Further finding identifies the type of project management practice in use, and over reliance on the use of deterministic approach as factors responsible for the low knowledge of uncertainties. The challenge therefore is how to improve the state of misconception among practitioners and to explore refinements to the traditional project management framework. To develop appropriate knowledge about uncertainty management, the notion that uncertainty management is about creating previously unknown information, must be repealed to embrace approaches encouraging information sharing, learning, and competence. The study provides an insightful perspective into understanding uncertainty in projects;and highlight possible refinements to extant project management practice in order to enhance uncertainty management within the construction sector.
Is the 52 Week High Strategy as Pervasive as Momentum? Evidence from Arabic Market Indices

Existing studies find that momentum can be explained by a strategy based on the 52wk high prices of individual stock and is able to predict returns. This paper uses Arabic market indices data to investigate whether there is momentum and 52wk high strategies and to evaluate the performance of these strategies to achieve the optimal portfolio. We find the 52wk high strategy is unprofitable when applied to Arabic market indices, while the momentum strategy is economically profitable than the 52wk high strategy. The 52wk high effect is not as pervasive and reliable as the momentum effect. After modifying the 52wk high strategy with long-term contrarian using a double sorting procedure, the modified 52wk high strategy has positive profits for all holding periods. However, the momentum strategy is still more profitable than this modified 52wk high strategy.

Researching with Communities: Towards a Leading Edge Theory and Practice for Community Engagement

This project seeks to determine the extent to which complexity theory might offer the most effective means for understanding how communities can be successfully engaged in and with academic research. In the project, we adopted a case study approach, working with participants in a number of projects which had significant community engagement. These projects were all supported by the UK Beacons for Public Engagement, with which we also collaborated in our work. From the outset our research was informed by a Community Advisory Group, comprising community partners and engagement specialists. The objective of our research was to identify the initial conditions that facilitated the creation of enabling environments for community engagement. A number of the research results challenged our theoretical assumptions. Revisiting these results, we were led to develop a new way of conceptualising community engagement, which we propose to call an „engagement cycle‟. We suggest that this engagement cycle comprises a number of differential „phases‟, each of which is constituted by its own characteristic processes. This notion of an engagement cycle raises further research questions relating to the applicability of complexity theory to community engagement, as well as suggesting a number of issues that may inform the future development of the Connected Communities community engagement strategy.

Transient Electromagnetic Wave Propagation in Anisotropic Dispersive Media

In this paper transient electromagnetic wave propagation in a stratified, anisotropic, dispersive medium is considered. Specifically, the direct scattering problem is addressed. The dispersive, anisotropic medium is modeled by constitutive relations (a 3 × 3 matrix-valued susceptibility operator)con taining time convolution integrals. In the general case, nine different susceptibility kernels characterize the medium. An incident plane wave impinges obliquely on a finite slab consisting of a stratified anisotropic medium. The scattered fields are obtained as time convolutions of the incident field with the scattering kernels. The scattering (reflection and transmission)k ernels are uniquely determined by the slab and are independent of the incident field. The scattering problem is solved by a wave splitting technique. Two different methods to determine the scattering kernels are presented; an imbedding and a Green functions approach. Explicit analytic expressions of the wave front are given for a special class of media. Some numerical examples illustrate the analysis. (Less)
Investigation of leptospirosis in febrile patients from Manabí communities (Ecuador)

The aim of this study was determine whether fever is associated with the presence of leptospiral DNA in human sera detected with Polymerase Chain Reaction (PCR). DNA was extracted from 576 samples of human serum (513 febrile and 63 non-febrile) obtained between February 2014 to July 2015 from semi-urban parishes Calderon and Santa Ana in Portoviejo city. DNA was analyzed first with real time PCR (PCR-RT), followed by conventional PCR to amplify the 16S ribosomal RNA (rrs) subunit from Leptospira sp. Finally, the 331 base pairs (bp) amplicons obtained were sent to be sequenced. The rrs sequences were detected in 2 out of 513 (0.5%) febrile patients and 0 of 63 (0.0%) from non-febrile patients.
Effects of blood collection on wild birds: an update

Blood sampling is often critical for answering a variety of questions about wild birds. However, it is important to assess the impacts, if any, of blood collection on wild birds. Here, we examined the effects of blood sampling on adults or nestlings in three species of free-living birds. First, we examined the effects of blood collection on annual survival and reproductive success in adult buff-breasted wrens Thryothorus leucotis in Panama. In adult wrens, blood collection from the brachial vein during the breeding season had no effect on annual survival or reproductive success. Second, we examined whether blood collection influenced mass gain in developing smooth-billed anis Crotophaga ani in Puerto Rico. In developing anis, blood collection from the femoral or jugular veins had no effect on mass gain of nestlings. Third, in developing European starlings Sturnus vulgaris in British Columbia, Canada, blood collection from the brachial vein had no effect of body condition. Blood collection from the jugular vein had a transient effect on body condition during the first week post-hatch, but this effect disappeared by the second week of age. Lastly, we present an extensive up-to-date review of the literature on the effects of blood collection on free-living avian species. Taken together, these data show that blood collection has no major negative effects on developing or adult birds in the wild.
Studies on the community ecology of cattle egrets Bubulcus ibis coromandus (Boddaert) in Jammu (Jammu and Kashmir), India

Some species of birds mirror an association with herbivores like buffaloes, cows, horses and goats to have their sustenance by feeding on insects living either near or on them. This paper attempts to document such associations of cattle egrets with the above mentioned mammals and birds like little egret, pond heron, common myna, cormorants and purple moorhen thereby throwing light on the various foraging parameters of cattle egrets in association with these animals. Cattle egrets are known to obtain more food in the association of herbivores with which they reflect commensalistic association whereas they are neutrally associated with birds. Besides, this piece of work provides information regarding parameters like time spent by cattle egrets in association with herbivore host species, number of hosts and egret steps per minute, location of foraging egret with respect to host (head, front legs or hind legs), number of attempts and items obtained per minute, capture success rate etc. In case of active foraging with cattle, number of strikes per minute was observed to be 10 to 13, average number of steps ranged from 8 to 9 whereas number of prey items captured was 4 to 6. Moreover, number of steps of cattle while foraging with cattle egrets was noted to be 11 to 13. Key words: Commensalistic Association, Foraging, Herbivore, Capture Success Rate.
Growth parameters of Pontoporia blainvillei and Sotalia fluviatilis (Cetacea) in northern Rio de Janeiro, Brazil

Growth parameters of 93 Pontoporia blainvillei and 84 Sotalia fluviatilis accidentally captured in gillnets or stranded along the sea coast of northern Rio de Janeiro State, Brazil (2137–2225S) were analysed (1989–96). Data of length-at-age was fitted by nonlinear Gompertz model. Growth parameters estimated for P. blainvillei were: sexual dimorphism in body length significant only to four years, so, length range of 0–3 years not showed growth differentiated; asymptotic length of 117.1 cm for males and 144.7 cm for females; length at birth of 71.0 cm; prenatal growth rate of 0.25 cm/day; birth occur in all seasons; males and females attain sexual maturity at two years, 115.0 cm and at three years, 130.0 cm, respectively. S. fluviatilis presented non sexual dimorphism in body length; asymptotic length of 191.7 cm for males and females; length at birth of 106.0 cm; prenatal growth rate of 0.31 cm/ day; birth occur from spring to autumn, with a peak during autumn; males and females attain sexual maturity at six years, with 180.0 cm for male and 160.0 cm for females. The results of the present study suggest that there are alterations in the reproductive investment in P. blainvillei. Probably, this species varies its growth strategies along its distribution. S. fluviatilis showed patterns similar to those observed for other populations of this species.
Economic Growth and Inequality in Nigeria: Magnitudes and Challenges

Economic growth is expected to lead to economic development and increase in the welfare of the masses. This is hoped to reduce the existing level of inequality. However, the most central problem in Nigeria economy today is that there is a sharp disconnect between the level of growth and development. What is rather obtainable is that there is growth without development because of the wide gap of inequality existing in the society. In this study we examine the phenomenon of growth-inequality nexus by employing trend analysis to examine the magnitude and the challenges of the prevailing inequality scenario in Nigeria. This paper therefore recommends good institutional framework and policy consistency to rectify the unwholesome situation of the high level of poverty and inequality prevailing in Nigeria.
A Methodology to Establish Usability Heuristics

Usability evaluation for applications based on emerging information technology brings new challenges. Is it the classical concept of usability still valid? Which are the dimensions of the (new) usability? How can it be measured? How should we develop for (better) usability? A methodology to develop usability heuristics for emerging applications is proposed. The methodology was fully checked in the case of Grid Computing applications, and partially applied in the case of Interactive Digital Television and Virtual Worlds.
Why Do Family Firms Strive for Nonfinancial Goals? An Organizational Identity Perspective

This paper develops an organizational identity–based rationale for why family firms strive for nonfinancial goals. We show that the visibility of the family in the firm, the transgenerational sustainability intentions of the family, and the capability of the firm for self–enhancement of the family positively influence the importance of identity fit between family and firm as well as the family's concern for corporate reputation. We suggest that the concern for corporate reputation leads the family to pursue nonfinancial goals to the benefit of nonfamily stakeholders. We also discuss reinforcing feedback loops in these processes.
Series 16E-002 Multi-plant Operation and Corporate Headquarters Separation : Evidence from Japanese plant-level panel data

This paper attempts to show (i) under what circumstances corporate headquarters (HQs) are separated from production plants and (ii) what type of plants are operated by multi-plant firms. By analyzing Japanese plant-level panel data from manufacturing censuses, we find that large-sized plants or plants intensively purchasing materials significantly tend to be separated from HQs and become a part of multi-plant operations. This suggests a role of managerial capacity. We confirm the robustness of our main findings by the dynamic switching patterns of plant status. Economic geography, such as distance from core, also appears to have impact.
Temperature Inferential Dynamic Matrix Control of Reactive Distillation Systems

Abstract Abstract Two-temperature inferential control of the ideal and the methyl acetate double feed reactive distillation (RD) systems operated neat is evaluated using constrained dynamic matrix control (CDMC) and traditional decentralized control. For the ideal RD system, significant improvement in the stripping tray temperature control and the transient deviation in the bottoms purity is observed using CDMC. For the methyl acetate system, CDMC results in significant improvement in the control of the two tray temperatures as well as transient deviations in both the distillate and bottoms purity. Results also show that the magnitude of the maximum through-put change for which the control system fails is noticeably higher using CDMC.
Ecological impact of a large Antarctic iceberg

Satellite imagery has been used to document for the first time the potential for large icebergs to substantially alter the dynamics of a marine ecosystem. The B‐15 iceberg (∼10,000 km2), which calved off the Ross Ice Shelf in the biologically productive southwestern Ross Sea, Antarctica, restricted the normal drift of pack ice, resulting in heavier spring/summer pack ice cover than previously recorded. Extensive ice cover reduced both the area suitable for phytoplankton growth and the length of the algal growing season. Consequently, primary productivity throughout the region was >40% below normal, which changed both the abundance and behavior of upper trophic level organisms.
On-line determination of hexazinone in water by solid phase extraction- UV/Vis spectrophotometry

In this work, the continuous determination of hexazinone in water was carried out by developing an online solid phase extraction by flow injection coupled with spectrophotometric detection. Variables related to hydrodynamic conditions were optimized by a full factorial design 3^2, of which the results were analyzed through an analysis of variance. Under the proposed optimal conditions, the principal figures of merit were a working range between 0.50 to 7.00 μg mL -1 of hexazinone; a precision of 4.6% expressed as variance coefficient; a limit of detection of 0.05 μg mL -1 , and a limit of determination of 0.16 μg mL -1 . Univariant calibrations based on the height or area of transitorial signals were compared to identify the best conditions for quantification. Samples of well and sea water were analyzed, obtaining satisfactory results in all cases in terms of precision and accuracy.
Interdependencies of Health, Education and Poverty: The Case of South Mediterranean Economies/Interdependencias de salud, educación y pobreza: el caso de las Economías Sur-Mediterráneas

This study is devoted to assessing the interdependencies between health, education and wealth at the aggregate regional level of South Mediterranean Countries (SMC) for the purpose of strengthening transversal economic and social policies. It looks first, to the major contributions of the previous literature developed on this subject. Theoretical and empirical studies at micro and macroeconomic levels prove that there are causal relations between variables related to health, education and wealth. As long as only partial and limited evidence exists on these interdependencies for the SMC, the second part is an empirical analysis based on World Bank, United Nations and on composite international indices. The results show that large interdependencies appear to be consistently exhibited by the data. Also, in the Granger sense of causality, health and education have been revealed to have important effects in leading these economies. The results attained are likely contributions for the enhancement of the economic and social policies to strengthen human development in the region. Este estudio esta dedicado a evaluar las interdependencias entre la salud, la educacion y la riqueza al nivel regional en el conjunto de los paises mediterraneos del sur, con el objetivo de reforzar las politicas economicas y sociales transversales. En primer lugar, se atiende a las principales contribuciones desarrolladas hasta el momento sobre este asunto. Estudios teoricos y empiricos a niveles micro y macroeconomicos comprueban la existencia de relaciones causales entre variables relacionadas con la salud, la educacion y la riqueza. No obstante, como solo hay evidencia parcial y limitada sobre la existencia de estas interdependencias para el SMC, la segunda parte es un analisis empirico basado en la informacion del Banco Mundial, de las Naciones Unidas y en indices internacionales compuestos. Los resultados muestran que las interdependencias parecen ser sustentadas por los datos. Ademas, en el sentido de la causalidad Granger, salud y educacion parecen tener efectos importantes liderando esas economias. Los resultados obtenidos pretenden contribuir a mejorar las politicas economicas y sociales dirigidas a reforzar el desarrollo humano en la region.
