Growth and competition in a warmer ocean: a field experiment with a non-native and two native habitat-building seaweeds

: Kelps and fucoids are important members of temperate seaweed communities, but may be negatively impacted by climate change and non-native species. We used a field experiment to investigate the effect of higher temperatures and a non-native seaweed, Sargassum muticum , on the kelp Saccharina latissima and fucoid Fucus serratus . All 3 are canopy-forming species which may grow together in the infralittoral and upper sublittoral zones in southwestern Norway. Artificial assemblages with different combinations of the species were placed in the shallow sublittoral, and length changes, weight changes and survival of the thalli were measured. This was done during a hot summer and again during a cool summer. The results showed that the species and their competitive interactions were affected by the different thermal conditions. S. latissima was the most successful species in the cool summer and had an impact on the other 2 species, but it was strongly negatively affected by the hot summer. Under these conditions, F. serratus became the most successful species, gaining the most weight. The effect of Sargassum muticum on the native species was no larger than the effect of intraspecific competition within those species. At the end of both summers S. muticum was in poor condition, potentially caused by low seawater nutrients resulting in low internal nitrogen.
Regional Entrepreneurship Capital and its Impact on Knowledge Diffusion and Economic Performance

We define a region’s capacity to generate firm start-ups as ”entrepreneurship capital”, which is an unobservable, hence latent variable. We then investigate the impact of this regional capital on regional economic performance, based on data for German Regions. We use a latent variable approach (LISREL) to do so. We find that entrepreneurship capital has a positive impact on regional economic performance. At the same time we find evidence that knowledge oriented measures drive entrepreneurship. Hence our empirical model provides evidence that entrepreneurship plays an important role in the knowledge spillover process. JEL-Codes: M13, O32, O47
Screening and Characterization of Bioactive Compounds of Turbinaria ornata from the Gulf of Mannar, India

To screen and characterize the bioactive compounds in the brown seaweed Turbinaria ornata. The brown seaweed, T. ornata was collected from Nalupanai coast of Gulf of Mannar. It was cleaned from epiphytes, washed, shade dried and powdered. Algal extraction was carried out using distilled water, ethanol, methanol, acetone and petroleum ether. The crude methanolic extract was subjected to GC-MS analysis to reveal the phyco-constituents. The results obtained in the phytochemical screening supports that the seaweeds contain biologically active substance. Methanol was identified as the most appropriate solvent to extract the bioactive compounds. Different fatty acids and volatile compounds were identified in the GC-MS analysis. The volatile mixture comprised of hydrocarbons, acids, aldehydes, ketones, esters, ethers, alcohols, halogenated and aromatic compounds. The study reveals the bioactive potential of T. ornata and to exploit its bioactive potentials for the production of valuable therapeutics and other related compounds of economic viability and social accessibility.
Re-Envisioning Member Checking and Communicating Results as Accountability Practice in Qualitative Research: A South African Community-Based Organization Example

Ethical considerations in communicating results to participants in community-based qualitative research are scrutinized less than in medical or genetics research. We report on ethical issues considered in planning, preparing and returning of study findings to members of a community-based organization who provide care and support services in their community in rural area in KwaZulu-Natal, South Africa. Using returning results as fulcrum, we explore the ethics of member checking and dissemination of findings. We propose revising these activities through ritual criticism aiming for the re-examination of routine ethics systems for the evaluation and improvement of practice. A case example illustrates how returning results comprise accountability practices through methods that are relevant, accessible, meaningful and useful to study participants. Finally, we consider how the dissemination of results to a wider audience might also be performed as accountability practices with deference to participants. Attention to representing results in forms that resonate with participants' frames of reference is called for. The term accountability practices or taking-it-back practices might describe the acts more authentically than current conventions motivating researchers to review current philosophical, ethical and methodological positions on member checking, returning results and dissemination practices.
The Effect of Using Cooperative Learning Strategy on Graduate Students' Academic Performance and Gender Differences

The study aimed to investigate the effect of using cooperative learning strategy on graduate students’ academic performance and gender differences in educational statistics and eduactional research methoud courses. The convenience sample used consisted (23) master’s students’ (18 female and 14 male) who study the educational statistics course, and (24) master’s students’ (13 female and 11 male) who study educational research method course from faculty of education at King Saud University. This study employed a quasi-experimental - nonequivalent control-group design with pretest, posttest and delyead posttest In this study, educational statistics performance test (ESPT) and educational research method test was used to measure the students’ performance. The both tests consisted of 30 multiple choice questions to collect the relevant data. The data collected was analyzed using independent samples t-test statistical methods. Findings of this study revealed that there was no significant difference in academic performance of male and female students at the pretest, posttest, and delayed posttest levels respectively. However, further investigations and analysis could be beneficial to obtain a complete vision of cooperative learning strategy for graduate students’ and invest more empirical research studies about teaching and learning strategies.

Management of Fusarium wilt of tomato under protected conditions using Brassica crop residues, AM fungi and biocontrol agents

Fusarium wilt of tomato was managed using three fungal, viz . Trichoderma viride , T. hamatum , T. harzianum and a bacterial viz . Pseudomonas fluorescens biocontrol agents in vitro . Four different genera of arbuscular-mycorrhizal (AM) fungi viz . , Glomus sp. , Acaulospora sp. , Scutellospora sp. and Gigaspora sp. were isolated from tomato soil and their culture consortium was multiplied on Guinea grass in pots. Under in vitro condition, T. viride was found most effective in inhibiting the mycelial growth of F. o. lycopersici . Amongst different bio-fumigant crop residues (fresh as well as dry) tested in vitro , taramira showed highest inhibition in mycelial growth of F. o. lycopersici i.e. 62.59 and 60.74 per cent, respectively. All the effective management inputs evaluated under in vitro conditions were again evaluated under polyhouse in an integrated manner. The results of polyhouse experiment indicated that bio-fumigation of sick soil with taramira crop residues for 30 days, and application of formulation of T. viride along with FYM and inoculation of transplants with indigenous AM fungi resulted in to more than 80% control of Fusarium wilt of tomato under polyhouse conditions. This practice also increased the growth viz . , height, number of branches and plant dry weight as well as yield parameters like number of fruits per plant and fruit yield per plot. Colony forming units (cfu/g) of Fusarium sp. were decreased while that of Trichoderma sp. increased in soil owing to treatment of soil with bioinoculants. The spore population of AM fungi was found more in the plots receiving this treatment as compared to control.
Connection between inner jet kinematics and broadband flux variability in the BL Lac object S5 0716+714

We present a high-frequency very long baseline interferometry (VLBI) kinematical study of the BL Lac object S5 0716+714 over the time period of September 2008 to October 2010. The aim of the study is to investigate the relation of the jet kinematics to the observed broadband flux variability. We find significant non-radial motions in the jet outflow of the source. In the radial direction, the highest measured apparent speed is \sim37 c, which is exceptionally high, especially for a BL Lac object. Patterns in the jet flow reveal a roughly stationary feature \sim0.15 mas downstream of the core. The long-term fits to the component trajectories reveal acceleration in the sub-mas region of the jet. The measured brightness temperature, T_{B}, follows a continuous trend of decline with distance, T_B \propto r_{jet}^{-(2.36\pm0.41)}, which suggests a gradient in Doppler factor along the jet axis. Our analysis suggest that a moving disturbance (or a shock wave) from the base of the jet produces the high-energy (optical to \gamma-ray) variations upstream of the 7 mm core, and then later causes an outburst in the core. Repetitive optical/\gamma-ray flares and the curved trajectories of the associated components suggest that the shock front propagates along a bent trajectory or helical path. Sharper \gamma-ray flares could be related to the passage of moving disturbances through the stationary feature. Our analysis suggests that the \gamma-ray and radio emission regions have different Doppler factors.
Exploring Variations in Income Growth in Southeastern United States

This paper examined income convergence in 875 counties of the 10-state southeastern region using Census data for 1980 and 2000. Logarithmic difference of average per capita income between those years was regressed on socioeconomic variables. Changes in education, labor force, and employment were strong determinants of income growth.
Strategic Fit and Supply Chain Performance (SCP): The Effect of Supply Chain Management (SCM) as The Mediator

Based on previous research, strategic fit among behavioural orientations can generate the behavioural planned to ensure the viability and performance of the firm. It is also mentioned before that behavioural orientation can also support company in increasing the supply chain performance. However, although behavioural orientation gives positive impact to SCP, companies are still challenged with issues such as, distortion of information, collaborative behaviours and many more that need to be managed well. To handle such issues, several authors recognized supply chain management (SCM) as a way that can mediate the relationship to improve performance. SCM enables seeks synchronization of intrafirm and interfirm operational and strategic capabilities into a unified, compelling marketplace force, and focuses supply chain partners on creating customer value. The importance of SCM as mediator should be considered as an important element to increase performance. Therefore, this study tries to theoretically investigate the potential benefits of SCM as a mediator to SCP. Also, it further explores the relationship of strategic fit between market orientation (MO) and supply chain orientation (SCO) to SCP. To investigate this relationship, this study proposes the covariance approach. The relationship and the covariance approach can be empirically tested for future research. © 2016 Published by Future Academy www.FutureAcademy. org.uk
Holoplankton, meroplankton, and meiofauna associated with marine snow

;\BSTRACT. The associations of holoplankton, meroplankton and me~ofauna with marine snow, as well CIS thelr behavior upon encountering marine snow, were investigated using SCUBA in the field and a vertical flume in the laboratory. Field san~ples were collected in the Atlantic Ocean off Charleston, South Carolina, USA. (3 dates) and in the Pacific Ocean at 2 locations in the San Juan Islands, Washington, USA (7 dates). Aggregates were present and abundant on all days (range 1 to 63 aggregates I-') but constituted a small percentage of the water column by volume (avg 0.078%). Holoplanktonic adult caldnoid and cyclopoid copepods, larvaceans, and copepod nauplii were found on aggregates. On average cl "/o of the calanoid and cyclopoid copepods sampled were on aggregates, indicating a weak dasociation with marine snow. In contrast, on average 2.6'%) of the larvaceans and 4.8% of the copepod nauplii sampled resided on aggregates, where they were, respectively, 33 to 62 times more concentrated on marine snow compared to the surrounding water. Percentages of harpacticoid copepods, nematodes, and foraminiferans on aggregates were 12.4, 69.9 and 47.2% respectively, and all were significantly concentrated on aggregates. Cyprids, bryozoan cyphonautes, and Iarval echinoderms were either weakly assoc~ated with or not found on aggregates. In contrast, bivalve and gastropod veligers and larval anthozoans were significantly concentrated on marine snow, with 5.8, 9.4, and 13,5%, respectively, found on aggregates. Observations in a vert~cal flume indicated that upon contacting marine snow calanoid and cyclopoid copepods swam away, copepod nauplii swam inside aggregates for several minutes before swimming off, and nematodes were observed to remain in aggregates throughout the observation period addlng material from the surrounding water to the 'home' aggregate. These observations suggest that plankters and meiofauna in the water column may spend several hours d" visiting or residing on aggregates, and may visit from 10s to 100s of aggregates d. '. The concentration and behavior of organisms on aggregates suggests that marine snow is an important component of the pelagic environment for a variety of both holoplanktonic and rneroplanktonlc zooplankton.

Etude de caractérisation des matériaux de la carrière de Sindia (Sénégal occidental) pour une utilisation en géotechnique routière

Cet article presente les resultats d’une etude de recherche sur la qualite des materiaux de graveleux lateritiques de la carriere de Sindia utilises en geotechnique routiere dans la partie occidentale du Senegal. De faibles valeurs de portance, de la resistance a la compression simple et du module d’elasticite sont les aspects les plus caracteristiques de ces materiaux. Ils peuvent donc etre utilises en couche de fondation d’une chaussee routiere. Les essais experimentaux ont montre qu’un traitement au ciment (avec un melange voisin 4%) permettrait d’ameliorer efficacement les proprietes geotechniques de ces materiaux pour une application en couche de base. Un calcul de dimensionnement integrant les resultats experimentaux illustre la possibilite d’une utilisation de ces materiaux pour une structure de chaussee de type T3+ ou T2-.
Export Restrictions and Market Uncertainty: Evidence from the Analysis of Price Volatility in the Ukrainian Wheat Market

The impact of export restrictions on market uncertainty has not been investigated before. This paper analyses the development of price volatility in the Ukrainian wheat market characterized by export restrictions during the commodity price peaks 2007/08 and 2010/11 within a dynamic conditional correlation GARCH model. We conclude that the export controls in Ukraine have not significantly reduced price volatility on the domestic wheat market. On the contrary, our findings suggest that the multiple and unpredictable political interference of the Ukrainian government on the wheat export market has substantially increased market uncertainty which led to pronounced additional price volatility in the market. The highly uncertain and unpredictable environment of wheat markets with restricted exports has dramatic consequences for the grain sector in Ukraine and prevents its further development.
Examining the moderating effects of firm generated content on online social brand engagement

This research furthers our understanding of the influence of social presence on social brand engagement (SBE) and the moderating effects of firm-generated content and consumer commitment. Employing a quantitative survey design, 738 consumers with prior experience in following brands on social media were randomly interviewed using online questionnaire. The findings suggest that social presence influence social brand engagement, however, this is significantly moderated by the firm-generated content and the consumers’ level of commitment in engaging with the brand. The findings provide insights into the potential role of SBE and social presence in advancing the broader understanding of brand relationship management, brand engagement and social media research.
EXTREMELY LOW EMITTANCE BEAM SIZE DIAGNOSTICS WITH SUB-MICROMETER RESOLUTION USING OPTICAL TRANSITION RADIATION

Transition radiation (TR) appearing when relativistic uniformly moving charged particle (or bunch of particles) crosses a boundary between two media with different dielectric properties is widely used as a tool for diagnostics of particle beams in modern accelerator facilities. The best resolution which can be achieved using beam profile monitors based on TR in optical wave range has a limitation caused by a spatial resolution of an optical system. Using a method based on analyzing a visibility of the TR Point Spread Function one can achieve a sub-micrometer resolution. In this report we shall represent the recent experimental results of a micron-scale beam size measurement at KEK-ATF2. We shall discuss the hardware status and future plans.
Penetration and Pathogenicity of Entomopathogenic Nematodes to Sugarcane Early Shoot Borer, Chilo infuscatellus Snellen (Lepidoptera: Crambidae)

Penetration and pathogenicity of seven species of entomopathogenic nematodes (EPN), viz., Heterorhabditis indica (LN2), H. bacteriophora (LN8), Heterorhabditis sp. (HII), Steinernema carpocapsae, S. glaseri, S. riobrave and S. feltiae to sugarcane early shoot borer, Chilo infuscatellus Snellen, was studied under laboratory conditions with bioassay techniques. Significant differences were observed in mean penetration of the EPNs in C. infuscatellus larvae. The penetration rate recorded was highest in S. glaseri followed by S. carpocapsae (29 and 18% respectively), while it was lowest in the three species of heterorhabditids, Heterorhabditis sp. (HII), H. indica (LN2) and H. bacteriophora (LN8). In pathogenicity studies, mortality of the early shoot borer larvae increased with increase in dosage. The larval mortality was 83.3 per cent at the dose of 50 infective juveniles (IJs) of H. indica and S. glaseri . It was least at 10 IJs/larva of all EPNs tested. The LD 50 values showed that S. glaseri was superior to all other EPN species (24.2 IJs/larva) followed by S. feltiae (26.6 IJs/larva).
Tunisian Labor Market and Regional Heterogeneity: Application of PSTR Model

This paper is devoted to investigating the matching process for Tunisia using desaggregated data by assuming that the rising of the unemployment rate result from regional disparities which yield variation of matching efficiencies across regions. Since most econometric aspects of spatial heterogeneity can be handled by means of the standard panel data methods, we focus our discussion on the new technique: Panel Smooth Transition Regression models (PSTR). The distinction is that we can compute regional specific sensibilities for 23 regions over the period 1984-2004. Given this objective, we consider three structural factors that allow explaining the regional imbalances. Contrary to the previous econometric techniques of the matching theory, estimates of the coefficients depend, of three transition variables. The results show that women insertion, the qualification share and population density significantly contribute to explain the asymmetry of the matching process across regions. Our main conclusion is that the hiring in Tunisia is driven essentially by the stock of vacancies about is the region. The willingness of job seekers, obviously, remains low, although it is different between regions and seems relatively important in urban zones.
Do sex-specific densities affect local survival of free-ranging great tits?

Competition within sexes is expected when resources are sex specific, whereas competition between sexes can occur when similar resources are exploited. Local population density and sex ratio will determine the amount of sex-specific interactions and thus the potential degree of sex-specific competition. In contrast, high densities and the density of same-sex individuals may also positively influence survival, for example, by facilitating the exploitation of resources. The population density and sex ratio may therefore differently affect survival of males and females and thus also affect the expected fitness gains of producing a certain offspring sex. In this paper, we investigate experimentally whether and how sex-specific local densities affected sex-specific annual local survival of juvenile and adult great tits. We manipulated the density and sex ratio of fledgling great tits in 12 forest plots during 3 consecutive breeding seasons and monitored local survival until the next breeding season. We found no negative effects of the number of same- or opposite-sex competitors on juvenile local survival. Instead, local survival of juveniles of both sexes increased with the density of same-sex fledglings. Adult local survival was negatively affected by an experimental increase in density of nestlings, yet associated positively with the natural breeding pair density in a plot. Juvenile local survival related negatively to breeding pair density. Our results reveal experimental evidence for both negative effects of density on adult local survival and positive sex-specific effects on juvenile local survival, which shape sex-specific fitness prospects and might thus also alter optimal sex allocation decisions.
