Use of Social Network Sites (SNS) by Library Academics in the Workplace: Perspectives of University Librarians in Sri Lanka

Libraries and in particular, university libraries around the globe are constantly revolutionized due to technological advancements which provide rich opportunities for libraries to embed blends of innovations into the work environment and render better services for their user communities. This research attempted to render views of library academics with regard to their current use of Social Network Sites (SNS) in the workplace. The objectives of the study were to investigate the background of SNS use by university library academics inclusive of their usage experience, skills and frequency of use, to examine the types of SNS used by them, professional purposes as well as personal purposes for using SNS in the workplace and to investigate the access methods and user perceptions towards SNS use in the workplace. Data were gathered from a study population of 116 university librarians in Sri Lanka via the survey strategy based on a questionnaire and the data analysis was done using descriptive statistics. The key findings of the study included that the majority (78.4%) of university librarians who participated in the survey used SNS in the workplace, respondents who had 1-5year experience in using SNS were in majority (44.8%), a high percentage (64.7%) of respondents assessed themselves as having “moderate experience” in using SNS, more than half (52.6%) of the respondents felt that they possessed adequate skills to use SNS, Facebook was the social network site most frequently used by the respondents (64.7%), most university librarians used SNS in the workplace to fulfill both professional and personal purposes, while the highest percentage of university librarians (58.6%) used SNS in the workplace for the specific professional purpose of “interacting with co-workers and professionals in the field” and the highest percentage of them (47.4%) used SNS for the specific personal purpose of “personal contact”, and the majority of them used the university network to access SNS in the workplace. Sri Lankan university librarians should keep pace with new innovative technologies such as SNS to remain worthy and important in this competitive digital world.
Exploratory Research on Relationship between Entrepreneurial Orientation Dimensions and Business Performance and Growth of Fast and Slow Growing Small and Medium Enterprises in Bosnia and Herzegovina

This paper analyses environment in fast (gazelles) and slow growing companies (mices) using Entrepreneurialorientation (EO) dimensions and business performance in terms of sales and employee growth. The research isdone using information on 178 small and medium enterprises (SMEs) in Bosnia and Herzegovina. We find thatEO dimensions are more present in gazelles than in mices. We show a small to moderate significant correlationbetween EO dimensions and business performance of gazelles and mices. Also, any change in sales growth andemployee growth might be associated with variability in innovation, risk taking and firm’s age.
Compost and Fertilizer - Alternatives or Complementary? Management Feasibility and Long-Term Effects on Soil Fertility in an Ethiopian Village

Decline in soil fertility due to nutrient depletion is a concern for low-input crop production in the highlands of Ethiopia. Fertilizer addition is insufficient due to infrastructural and socioeconomic constraints. Effects of compost addition, alone or in combination with NP fertilizer, on crop productivity and soil fertility were studied in long-term onfarm experiments in Beseku, Ethiopia. The combined treatment resulted in an added benefit (synergy), i.e., a higher yield than when compost or fertilizer was added alone. The highest yield increase was found for maize where the combined treatment had 78% and 26% higher yields compared to the control and fertilizer treatment, respectively. Plant available concentrations of B, P, S, and Zn increased in the compost and/or the combined treatment compared to the control. Soil organic carbon and total nitrogen stocks increased in the combined treatment compared with the fertilizer treatment. Substrate-induced respiration from the combined treatment was lower compared to the compost treatment, but catabolic versatility was higher in the combined treatment compared with the compost and the control. This suggests that a combination of compost and fertilizer induces a wider microbial catabolic capability which might lead to higher nutrient mobilization. The apparent yield synergy in the combined treatment likely attributed to; (1) alleviation of microand macronutrient limitations allowing for a more efficient use of fertilizer N and P and/or (2) improvement of the soil microbial catabolic capability. However, the indirect effects of compost on soil physical properties leading to improved nutrient use efficiency are also a possible explanation. The plot level N balance was strongly negative for the fertilizer treatment and the control, whereas it was close to steady-state in the combined and compost treatments. All treatments except the control had positive P balances. Therefore, the addition of compost, alone or in combination with fertilizer, improves the nutrient status of the soil and serves as a complement to fertilizer use reducing the dependence on mineral fertilizer in low-input crop production systems. The major factor limiting the adoption of compost by farmers was lack of knowledge. Practical and theoretical training had a positive effect on adoption.
An assessment of human-elephant conflict and associated ecological and demographic factors in Nilambur, Western Ghats of Kerala, southern India

Elephant conservation carries cost in the form of human-elephant conflict and affects the wellbeing of people living near ecologically important areas. Conflicts impart serious challenges towards the survival of Asian Elephants, which are categorized as Endangered in the IUCN Red List of Threatened Species. Issues of wildlife conservation are least addressed in areas with less restricted categories of protection. Hence an attempt was made to evaluate the intensity of elephant conflict and factors associated with its occurrence in villages with forest fringes of North and South Forest Divisions of Nilambur, Kerala, southern India. It was hypothesized that variables such as number of houses, area of village, livestock population, forest frontage, and presence of water source along the forest boundary abutting the village to be the underlying correlates of conflict. Field studies were conducted fortnightly from June 2014 to May 2015, by visiting farms and households of 17 selected forest fringe villages. Observational methods, questionnaire surveys and secondary data collection were employed for this purpose. A total of 277 incidents of crop depredation, 12 incidents of property damage, three human injuries, and one human death due to conflict were recorded during this period. Crop raiding was highest during post monsoon season and it was low during pre-monsoon and monsoon seasons. Multiple linear regression results suggest that forest frontage and livestock population were significant predictors of conflict incidence. Information regarding the prime causes of conflict will be helpful for planning strategies for the establishment of appropriate mitigation methods. The present study serves as baseline information which will be helpful for formulating prospective management plans.
How Review Quality and Reviewers' Photos Affect Consumers' Evaluations of the Product and the Website: The Moderating Role of Product Type

This study aimed to elucidate the effects of review quality and reviewer representation in forming consumer’s attitudes. In so doing, if, and if so, how product type varies the effects of those two factors was also explored. In order to answer these questions, a 2 (review quality: high vs. low) x 2 (reviewer representation: photos vs. abstract figure) x 2 (product type: experience vs. search) between-subject experiment was conducted online. The product reviews used were mostly positive toward the target product. First, participants who read high quality product reviews evaluated the reviewers, product and seller website more positively than those who read low quality reviews. Second, reviewers’ profile photos did not evoke higher or lesser social presence than abstract figures did. Likewise, there was no difference in evaluations of reviewers, product, and website between photos and figures. However, photos made people more likely to differentiate high quality reviews from low quality reviews, with high quality reviews eliciting more positive website evaluation than low quality reviews. In addition, photos hindered correct recognition of product descriptions (information given by the seller), although they did not significantly alter the recall of review content (information given by the reviewers). Third, product type interacted with review quality, but not with reviewer representation. For search goods, which refers to the products whose quality is easily predicted before purchase, high quality reviews significantly increased purchase intention. However, the effect of review quality was not found for experience goods, which are defined as the products whose values are hardly assessed before firsthand experience. Theoretical and practical implications of these results were discussed.
Heavy Metal Contamination Levels in Topsoil at Selected Auto Workshops in Accra

This work has the objective to ascertain the heavy metal contamination levels in topsoil at auto workshops and also determine the anthropogenic and crustal contributions. Surface soil dust samples of particle sizes below 100 µm from two roadside auto-workshops were analyzed using Energy Dispersive X-Ray Fluorescence Analysis to investigate the heavy metal contents. 18 elements were identified in each soil sample collected from the two roadside auto-workshops. Pollution indices {enrichment factor (EF), contamination factor (CF), degree of contamination (DC), pollution load index (PLI),} were used to assess the contamination status of the heavy metals in the soil samples. Generally the elements Zn, Pb, Cu, Ni, Pb were found to be mostly of anthropogenic origins. The extent of contamination observed at the two sites for most of the metal elements ranged from moderate to considerable contamination. Lead (Pb) was revealed to be the greatest contaminant and was found to be mostly very high at the electrical shops. The anthropogenic contributions to the soil dust contaminants are largely in the small particle size fractions.
Virulence profiles of pathogenic Escherichia coli strains isolated from street foods in Bénin

This study aimed to evaluate the risk incurred by street foods consumers, through the characterization of Escherichia coli strains isolated from food samples collected in two major cities of southern Benin. After bacterial identification, the sensitivity of isolated E. coli strains was determined by the disc diffusion method. The phenotypic and genotypic characterization of E. coli strains that produce beta-lactamase and toxins were made respectively by acidimetric and PCR method. This study revealed that about 38.70% of analyzed samples were contaminated by E. coli. The phenotypical investigation showed respectively that in dry and rainy season, 100% and 21.43% of E. coli strains produced penicillinase. The blaTEM, blaSHV and blaCTX-M genes were respectively carried by 80.96%, 4.76% and 14.28% of E. coli strains producing penicillinase. 4.35% of isolated E. coli strains carried STEC: shigatoxin E. coli (SLTI: Shiga-like toxin I) whereas 47.83% carried STEC: shigatoxin E. coli (SLTII: Shiga-like toxin II) followed by enterohemorragic E. coli (VTEC) (30.43%) and then enterotoxigenic E. coli (ETEC) (17.39%).
The Gender Gap Cracks Under Pressure: A Detailed Look at Male and Female Performance Differences During Competitions

Using data from multiple-period math competitions, we show that males outperform females of similar ability during the first period. However, the male advantage is not found in any subsequent period of competition, or even after a two-week break from competition. Some evidence suggests that males may actually perform worse than females in later periods. The analysis considers various experimental treatments and finds that the existence of gender differences depends crucially on the design of the competition and the task at hand. Even when the male advantage does exist, it does not persist beyond the initial period of competition.
Venture Capitalists’ vs. Philanthropic Venture Capitalists’ Human Capital: An Exploratory Study

Philanthropic venture capital (PhVC), like traditional venture capital (TVC), provides funding and value added services to its portfolio ventures, but unlike TVC, these investees typically have a social mission. PhVC has a main ethical dimension and aims at maximizing the social return on the investment. This paper examines nascent PhVC firms and, in particular, focuses on its human capital (HC), offering a comparative analysis with nascent TVC firms. Results show that both at a general and at a specific HC level, PhVC firms are different from TVC firms. With respect to general HC, PhVC firms tend to exhibit lower levels of education at the BS and MBA levels but a higher number of graduate technical degrees, suggesting the existence of a substitution effect in education. At the specific HC level, PhVC firms exhibit lower experience than TVC firms, except for governmental, and non/profit experience; differences at firm level between commercial and social specific HC hold significant.
HCV Infection and NS-3 Serine Protease Inhibitors

Infection with Hepatitis C Virus (HCV) is a major health problem affecting 270 million people worldwide and 10 million people in Pakistan. Currently, there is no vaccine available for prevention of HCV infection due to the high degree of strain variation. The current standard of care is a combination of Pegylated interferon ? (PEG-INF ? ) with ribavirin and Boceprevir/Telaprevir. Hence, there is a need to develop new antiviral agents from different targets. HCV NS3, a nonstructural protein has serine/protease and helicase domain, and these domains are considered as important antiviral drug targets to combat HCV. In the past 15 years, major scientific advances have enabled the development of many novel serine/protease and helicase inhibitors by using in vivo as well as in vitro model systems. Most of NS3 protease inhibitors have entered in different clinical trials phases but still there is a need to improve the functionality of these inhibitory compounds. This review summarizes potent antiviral compounds against HCV NS3 protease and their activity in combination with standard therapy. In conclusion, it will be very exciting to see HCV NS3-4A serine protease/helicase inhibitors progress through clinical developments and, hopefully, provide hepatitis C patients with much needed, more effective therapies.
Placental Malaria Parasitization at Delivery: Experience at a Nigerian Tertiary Hospital

Background: In malaria endemic areas, pregnant women are constantly at risk of repeated malaria infestation which if left untreated, poses a significant threat to the health and survival of the mother and her baby. Objective: This study determined the prevalence and risk factors for placental malaria parasitaemia among parturients at the Federal Medical Centre, Yenagoa, Nigeria. Methodology: A prospective cross-sectional analytical study of 205 parturients recruited consecutively at presentation for delivery. An interviewer-administered questionnaire was used to collect data. After delivery, placental blood was collected for microscopy to detect malaria parasites. Data was analysed using SPSS version 22. Results: The prevalence of placental malaria parasitaemia was 13.7%. Maternal age <25 years (P<0.001), low educational status (P = 0.03), low parity (P = 0.03), unbooked status (P < 0.001) and non-use of intermittent preventive treatment (P <0.001) were significantly associated with placental malaria parasitaemia. Receiving three or more doses of sulphadoxine-pyrimethamine for intermittent preventive treatment of malaria in pregnancy was by far, more protective for placental malaria than receiving 2 doses (odds ratio = 0.25). Plasmodium falciparum was the only parasite species detected. Conclusion: Malaria still ravages our obstetric population and the significant contributors include low maternal age, low educational status, low parity, unbooked status and non-use of intermittent preventive treatment in pregnancy. Women should be encouraged to utilize antenatal care. There should be a prompt adoption of the recent WHO recommendations regarding malaria prophylaxis in pregnancy in all obstetric units and the medication should be given as Directly Observed Therapy.
STUDENTS’ PROBLEMS IN MAKING DERIVATIONAL WORDS

This paper aims to find out what kinds of errors the students made in making derivational words and the most frequent errors occurred. It is a descriptive qualitative research which focuses on the error analysis of derivational morphology. The subject of this study was the students of English Education UNNES batch 2012. By using quota sampling, 25 students were taken for the try-out test and another 25 students were taken for the real test. The data were obtained from a test and questionnaire. In analyzing the data, the researcher used error analysis method. It consists of identifying errors, describing errors, explaining errors and error evaluation. The finding errors were analyzed based on the Surface Structure Taxonomy that specifies four types of errors namely omission, addition, misordering and misformation. The result showed that errors were found in all categories of derivational morphology. There were 146 errors which consisted of 98 (67,1%) misformation, 34 (23,3%) omission, and 14 (9,6%) addition. Thus, it was crystal clear that the most frequent errors occurred in misformation.
EXCITATION OF COUPLED STELLAR MOTIONS IN THE GALACTIC DISK BY ORBITING SATELLITES

We use a set of high-resolution N-body simulations of the Galactic disk to study its interactions with the population of cosmologically predicted satellites. One simulation illustrates that multiple passages of massive satellites with different velocities through the disk generate a wobble, which has the appearance of rings in face-on projections of the stellar disk. They also produce flares in the outer disk parts and gradually heat the disk through bending waves. A different numerical experiment shows that an individual satellite as massive as the Sagittarius dwarf galaxy passing through the disk will drive coupled horizontal and vertical oscillations of stars in underdense regions with small associated heating. This experiment shows that vertical excursions of stars in these low-density regions can exceed 1 kpc in the Solar neighborhood, resembling the recently locally detected coherent vertical oscillations. They can also induce non-zero vertical streaming motions as large as 10–20 km s−1, which is consistent with recent observations in the Galactic disk. This phenomenon appears as a local ring with modest associated disk heating.
Listening to galaxies tuning at z ~ 2.5–3.0: The first strikes of the Hubble fork

We investigate the morphological properties of 494 galaxies selected from the GMASS survey at z>1, primarily in their optical rest frame, using HST images, from the CANDELS survey. We propose that the Hubble sequence of galaxy morphologies takes shape at redshift 2.5 1, such that at redshifts z=2.5-2.7 and above, the Hubble types cannot be identified, and most galaxies are classified as irregular. The quantitative morphological analysis shows that, at 1<z<3, morphological parameters are not as effective in distinguishing the different morphological Hubble types as they are at low redshift. No significant morphological k-correction was found to be required for the Hubble type classification, with some exceptions. In general, different morphological types occupy the two peaks of the rest-frame (U-B) colour bimodality of galaxies: most irregulars occupy the blue peak, while ellipticals are mainly found in the red peak, though with some level of contamination. Disks are more evenly distributed than either irregulars and ellipticals. We find that the position of a galaxy in a UVJ diagram is related to its morphological type: the "quiescent" region of the plot is mainly occupied by ellipticals and, to a lesser extent, by disks. We find that only ~33% of all morphological ellipticals in our sample are red and passively evolving galaxies. Blue galaxies morphologically classified as ellipticals show a remarkable structural similarity to red ones. Almost all irregulars have a star-forming galaxy spectrum. In addition, the majority of disks show some sign of star-formation activity in their spectra, though in some cases their red continuum is indicative of old stellar populations. Finally, an elliptical morphology may be associated with either passively evolving or strongly star-forming galaxies.
Preclinical evaluation of the crude extract from the fruits of Punica grantaum L. (Punicaceae) for antimicrobial activity in in vitro and ex vivo experimental models: A comparative study

Currently, natural products have been evaluated as sources of antimicrobial agents. Considering the increasing use of pomegranate, it has become important to establish a correlation between the phytocompounds and the antimicrobial properties of the crude extract used in Brazilian folklore medicine. The compositional analysis revealed the presence of classes of secondary metabolites of pharmaceutical interest, among them, tannins, flavonoids and phenolic compounds. The in vitro study was performed by broth micro-dilution susceptibility assay according to the protocols of the National Committee for Clinical Laboratory Standards and described the antibacterial and antifungal activities of the extract. The preeminent antimicrobial activities were recorded against Staphylococcus aureus and Staphylococcus epidermidis. In order to estimate the ex vivo antimicrobial activity of the extract, serum and granulomatous tissues were separately submitted to microbiological assay. The crude extract did not present any inhibition zone. Thus, it is possible to suggest that after the oral ingestion of the extract, bacteria present in the gastrointestinal tract of the animal, hydrolyze phytocompounds, which present antimicrobial potential in in vitro models but do not present sufficient serum and tissue concentrations to exert this activity in ex vivo and presumably in in vivo models. Key words: Punicaceae, Punica granatum L. , preclinical, antimicrobial, in vitro, ex vivo.
