Towards a More Realistic Citation Model: The Key Role of Research Team Sizes

We propose a new citation model which builds on the existing models that explicitly or implicitly include “direct” and “indirect” (learning about a cited paper’s existence from references in another paper) citation mechanisms. Our model departs from the usual, unrealistic assumption of uniform probability of direct citation, in which initial differences in citation arise purely randomly. Instead, we demonstrate that a two-mechanism model in which the probability of direct citation is proportional to the number of authors on a paper (team size) is able to reproduce the empirical citation distributions of articles published in the field of astronomy remarkably well, and at different points in time. Interpretation of our model is that the intrinsic citation capacity, and hence the initial visibility of a paper, will be enhanced when more people are intimately familiar with some work, favoring papers from larger teams. While the intrinsic citation capacity cannot depend only on the team size, our model demonstrates that it must be to some degree correlated with it, and distributed in a similar way, i.e., having a power-law tail. Consequently, our team-size model qualitatively explains the existence of a correlation between the number of citations and the number of authors on a paper.
The effect of accidentally introduced red swamp crayfish (Procambarus clarkii) in Kafue fishery

A study using semi-structured questionnaires, interviews and focus group discussion, was conducted to assess the effect of accidentally introduced red swamp crayfish (Procambarus clarkii) in Stratum IV (Namwala district) of the Kafue fishery. The study revealed that gillnets of 2 inches (50mm) and above were more effective in capturing P. clarkii. It was also clear that fishers faced greater challenges due to the emergency of crayfish as part of their by-catch since most of them did not consider crustaceans as food and hence, either returned them into the water or threw them away. In addition, fishers faced the problems of net tearing as they removed the crayfish from the nets as the organisms got caught through entangling. The crayfish posed problems of predating on caught fish, thus lowering the quality of the saleable fish. The crayfish had sharp chelates that caused undesirable biting effect, which resulted into injuries to fishers in their effort to remove the organism from the nets. It was also observed that the increase in crayfish was only noticed in the last 5-10 years. However, the numbers of the crayfish caught showed strong seasonal variation, with the hot season recording the highest numbers of crayfish per finfish with cold season recording the least and the rainy season having intermediate catches. The quantity of crayfish caught in gillnets, were also depth dependent, with the bottom setting being the most effective, the mid setting coming after that and top setting being the least. In a similar manner, nets set close to the shoreline realized increased levels of crayfish by-catches. Fishers also attributed low levels of finfish and crabs catches to the emergence of the crayfish.
Measuring chromosome-end fusions in fission yeast

Telomeres protect eukaryotic chromosomes from illegitimate end-to-end fusions. When this function fails, dicentric chromosomes are formed, triggering breakage-fusion-bridge cycles and genome instability. How efficient is this protection mechanism in normal cells is not fully understood. We created a positive selection assay aimed at capturing chromosome-end fusions in Schizosaccharomyces pombe. We placed telomere sequences with a head to head arrangement in an intron of a selectable marker contained on a plasmid. By linearizing the plasmid between the telomere sequences, we generated a stable mini-chromosome that fails to express the reporter gene. Whenever the ends of the mini-chromosome join, the marker gene is reconstituted and fusions are captured by direct selection. Using telomerase mutants, we recovered several fusion events that lacked telomere sequences. The end-joining reaction involved specific homologous subtelomeric sequences capable of forming hairpins, suggestive of ssDNA stabilization prior to fusing. These events occurred via microhomology-mediated end-joining (MMEJ)/ single-strand annealing (SSA) repair and also required MRN/Ctp1. Strikingly, we were able to capture spontaneous telomere-to-telomere fusions in unperturbed cells. Similar to disruption of the telomere regulator Taz1/TRF2, end-joining reactions occurred via non-homologous end-joining (NHEJ) repair. Thus, telomeres undergo fusions prior to becoming critically short, possibly through transient deprotection. These dysfunction events induce chromosome instability and may underlie early tumourigenesis.
Studies on Epidemiology of Tomato Leaf Curl Virus

Tomato crop planted during the months of December to May are subjected to low rainfall, low humidity and high temperature which helped for high population of whitefly and high TLCV incidence resulting in low yield. Whereas the tomato planted during July to November are subjected to high rainfall, high humidity and low temperature, resulting in low whitefly population, low incidence of TLCV with better yield of tomatoes.
Evaluation of salicylic acid as a systemic resistance inducer against meloidogyne incognita on tomato cv. Co3

Salicylic acid is a natural phenolic compound present in many plants and is involved in induction of pathogenesis related proteins in various crops including tomato. Root dip and foliar application of salicylic acid on tomato cv. Co3 @ 50, 100 and 200 ppm affected the development of the root-knot nematode, Meloidogyne incognita, and significantly increased plant height (82.6 cm), root length (16 cm), shoot weight (95.8 g), and root weight (13.5 g) at 90 days after transplanting. Among the different methods of application of salicylic acid (SA) treatments, highest reduction in number of galls/plant, number of egg masses/plant, and soil nematode population, was obtained with two foliar sprays of 200 ppm SA, compared to untreated control.
Community Mediators in Malaysia: Profile and Analyses on their Roles and Challenges

Community mediation is a powerful mechanism to manage conflict in a multiracial society. Various efforts have been made in Malaysia to improve communal relationships including the training of community leaders as community mediators. Though there have been reports on the growing numbers of trained mediators, not much is known about their profiles and experiences. In the proposed research, selected community leaders would undergo a four-phase training for mindset setting, skill learning and confidence building and be invited to attend case conferences as refresher courses over time and as an opportunity to discuss any stumbling blocks in ongoing case management. Based on a self-administered survey with 139 trained mediators, the profile of the community mediators was outlined and the challenges that they faced were discussed at agency, interpersonal and societal levels. The findings shed light on the current state of affairs of Malaysian community mediators in addition to providing input that would help community mediators in their role in the context of managing communal conflicts.
Genetic Diversity of Cephalotaxus mannii, a Rare and Endangered Plant

Using RAPD technique, the DNA diversity of Cephalotaxus mannii Hook. f. , its genetic diversity pattern, the reasons for its endangered position and conservative approaches were studied. The results show that: 1. The genetic diversity of C. mannii collected from five localities in Hainan is low, and its adaptability to environmental change is weak. 2. The differences of genetic diversity between intra- and inter-populations are great, and the major variation distributes within the population (DNA diversity is 85.1%). 3. The excessive lumbering, man-made destruction, violent typhoon, edible value of the seeds and genetic drift were the main reasons for the low-level genetic diversity of C. mannii and its endangered position. 4. The difference of the micro-environment and other random factors affecting the population should also be taken into full consideration in the study and in protection of such occasionally scattered plants. 5. Enforced measures should be taken to protect the present population, enlarge the population and lower the loss rate of its gene. Mt. Limulin should be chosen as a conservative spot because of its high genetic diversity and less destruction of the forest. Meanwhile, the protection of other populations should be enforced. 6. The differences within and between the populations are great based on different primers used. The change of proportions in polymorphic loci between the populations is more than that between the primers.
Traits to stay, traits to move: a review of functional traits to assess sensitivity and adaptive capacity of temperate and boreal trees to climate change

The integration of functional traits into vulnerability assessments is a promising approach to quantitatively capture differences in species sensitivity and adaptive capacity to climate change, allowing the refinement of tree species distribution models. In response to a clear need to identify traits that are responsive to climate change and applicable in a management context, we review the state of knowledge of the main mechanisms, and their associated traits, that underpin the ability of boreal and temperate tree species to persist and (or) shift their distribution in a changing climate. We aimed to determine whether current knowledge is sufficiently mature and available to be used effectively in vulnerability assessments. Marshalling recent conceptual advances and assessing data availability, our ultimate objective is to guide modellers and practitioners in finding and selecting sets of traits that can be used to capture differences in species’ ability to persist and migrate. While the physiological me.
Thermal Responses in the Capercaillie Tetrao urogallus and the Black Grouse Lyrurus tetrix Roosting in the Snow

Thermal responses were studied in the capercaillie and the black grouse roosting in closed snow burrows in northern Finland. For capercaillie, the air temperature within the burrow declined with the distance from the bird but was as high as 11 C adjacent to the bird when snow temperatures varied between -7.5 and - 11.5 C. The body temperature of the burrowed capercaillie was significantly lower than that of those roosting on the snow surface, indicating lessened alertness. In a comparison of the responses of the two species, the body temperature of burrowed black grouse was significantly higher than that of similarly situated capercaillie. The burrowed black grouse shivered occasionally but weakly during the night. Measurements of pectoral muscle electromyographic activity (EMG) were not taken for capercaillie. The results support the hypothesis that in winter, under suitable snow conditions, these birds are able to shelter in, or close to, a thermoneutral microenvironment.
Detecion of CEBPA gene mutations in acute myeloid leukaemia and its clinic significance

Objective To investigate the detection rate of CEBPA(CCAAT-enhancer binding protein-alpha,CEBPA)mutations in acute myeloid leukemia(AML) and its clinic significance.Methods The entire coding region of the CEBPA gene was detected in 123 untreated AML patients with normal karyotype using polymerase chain reaction(PCR)followed by sequence analysis and fragment length analysis.38 normal donors from the allogeneic stem cell transplantation were served as control.Results 32 cases with CEBPA mutation were found in 123 AML patients with normal karyotype,including 1 in 3 cases of the French-American-British(FAB)subtype M1,23 in 58 cases of M2(39.7%),4 in 19 cases of M4(21.1%),2 in 14 cases of M5(14.3%)and 2 in 7 cases of M6.No mutation was found in 2 with M0,19 with M3,and 1 with M7.The total detection rate of CEBPA mutations was 26.0% in 123 AML patients with normal karyotype.The detection rate was higher in M2 than that in M3(P0.05),but the result in M2 was not statistically significant compared with that in M4 or M5(both P0.05). Moreover,CEBPA mutations were significantly associated with a higher blast counts in the bone marrow and lower platelet counts in the peripheral blood(both P0.05),but not hemoglobin and white blood cell counts in the peripheral blood(both P0.05). Conclusions A total of 32(26.0%)out of 123 screened AML patients with normal karyotype are found to carry CEBPA mutations after excluding all known CEBPA polymorphisms.The detection rate is higher in M2 than that in M3.Patients with CEBPA mutations have a higher blast counts in the bone marrow and a lower platelet counts in the peripheral blood.
Model-Based Prediction of Amplitude Scintillation Variance Due to Clear-Air Tropospheric Turbulence-Antennas and Propagation, IEEE Transactions on

A statistical method to predict tropospheric amplitude scintillation parameters along earth-space microwave links from meteorological data is proposed. The evaluation of the mean value and the variance of the refractive-index structure constant and of the scintillation power (i.e., the variance of the log-amplitude fluctuations of the received electromagnetic field) is carried out from conventional radio-sounding measurements. A large radio-sounding data set, collected in Northern Italy over ten years is utilized to simulate clear-air amplitude scintillation variance at microwaves and millimeter-waves on slant paths. Scintillation statistics of interest for link-budget design are also derived from the radio-sounding data set for short and long-term applications. Scintillation prediction formulas, based on measurements of surface temperature and relative humidity, are also derived and regression coefficient tables are given on an hourly and a monthly basis. Comparisons of short-term and long-term prediction results with Olympus down-link measurements at 19.8 GHz are shown and discussed. A model investigation about the statistical correlation between scintillation power and brightness temperature is performed, deriving an extension of the estimation methods to include integrated water vapor measurements from ground-based microwave radiometers.
Factors Affecting Brand Purchase Intention of Automobiles in Malaysia

Studies on customers’ purchase intention has always been one of the most fascinating topics in marketing research because purchase intention has been considered as the most accurate predictor for forecasting actual purchase behavior. It is important to investigate this construct in the context of the Malaysian automobile market which is facing numerous uncertainties under the increasing pressure of globalisation. Proton and Perodua, the two Malaysian automobile brands, are losing their market shares to the other external brands from outside. However, compared to the other brands, automobile brands from Japan are showing good performance in terms of their market share. Therefore, this study aims to investigate customers’ brand purchase intention of automobiles in the Malaysian context. A survey using self-administered questionnaires was conducted to 252 working adults in Klang Valley, Malaysia, and statistical analysis was performed to test the hypotheses. Brand Credibility (BC), Perceived Quality (PQ), Perceived After-Sales-Service Quality (PASSQ), Price Perception (PP), Resale Price Perception (RPP), Product Appearance (PA), and Subjective Norm (SN) were measured as the influencing factors. Brand Purchase Intention (BPI), the only dependent variable, was measured as a probability for repeat purchase on the same brand. The analysis showed that Brand Perception which consists of Brand Credibility and Perceived Quality is the most influential factor on brand purchase intention in Malaysia, followed by Subjective Norm, Price Perception and Product Appearance. The result also showed that Perceived After-Sales-Service Quality and Resale Price Perception have no significant influence on customers’ purchase intention.
Azimuthal anisotropy of Hudson Bay using seismic interferometry

The Hudson Bay basin is the least studied of the four major Phanerozoic intracratonic basins in North America, which include the hydrocarbon-rich Williston, Illinois and Michigan basins. Using azimuthal anisotropy results in conjunction with isotropic group velocity maps from previous work, we can further focus our study on determining the formation and regional crustal structure beneath Hudson Bay. Twenty-one months of continuous ambient-noise recordings have been acquired from 37 broadband seismograph stations that encircle Hudson Bay. These stations are part of the Hudson Bay Lithospheric Experiment (HuBLE), an international project that is currently operating more than 40 broadband seismograph stations around the periphery of Hudson Bay. The inter-station group-velocity dispersion curves found from noise-generated seismic-interferometry studies, also know as ambient-noise tomography, are input into a tomographic inversion procedure producing images of crustal azimuthal anisotropy. This study marks the first where ambient seismic-noise data have been considered in azimuthal anisotropy work. Our resolution testing suggests that the interpretation of the results requires some caution, but good path coverage is available. Preliminary results show a dominant southwest-northeast anisotropic direction, with weak correlation with the tectonic belts. In contrast, previous anisotropic studies have found that crustal anisotropy is strongly correlated with regional geology. Our results suggest that contributions from other forces may be important. Stresses, including large-scale regional stresses from plate motion are considered, but also show little correlation with our data. Local glacial isostatic rebound may be a contributing factor, but further work is required. INTRODUCTION Hudson Bay is a vast inland sea that overlies the Paleozoic Hudson Bay basin, an intracratonic basin with similar stratigraphic record to the hydrocarbon rich Williston, Illinois and Michigan basins. The processes of formation of the intracratonic basins such as Hudson Bay are poorly understood; this study seeks clues to achieve a better understanding of these processes by investigating regional crustal structure. Although the method of investigation, known as ambient noise tomography (or seismic interferometry) has been widely used in the past 5 years (e.g., Shapiro et al. 2005; Curtis et al., 2006; Yao et al., 2006; Yang et al. 2007; Moschetti et al. 2007; Lin et al. 2007, 2010), this study is one of the first to incorporate seismic anisotropy into the analysis. In this paper we apply seismic interferometry to 37 broadband seismograph stations located around the perimeter of Hudson Bay (FIG 1) with continuous recording for 21 months. The present study builds on earlier work (Pawlak et al. 2010) in which we imaged the tectonic structure of the crust and upper mantle beneath Hudson Bay based on
Frequency and Antimicrobial Pattern of Staphylococcus aureus Isolated From Patients with Infected Wound Attending Wad Madani Teaching Hospitals

DOI: 10.21276/sjbr.2018. 3.3. 4 Abstract: Wounds are a significant cause of morbidity worldwide, studies show that for every million wound patients, at least 10.000 die from microbial infections. The skin is a vital organ that serves as a protective barrier between the human bodies on its external environment. Staphylococcus aureus has been known as a cause of deepseated wound infection for close to a century, having recognized as a cause of nosocomial infection and super infection in patients receiving antimicrobial agent such as surgical cases. MRSA colonizing the anterior nares and skin of human are the major sources of surgical site infection as well as nosocomial spread. Methicillin-resistant Staphylococcus aureus (MRSA) are bacteria resistant to penicillin and cephalosporin classes of antibiotics and are often resistant to many other classes of antibiotics. Importance of S. aureus as persistent nosocomial and community acquired pathogen has become a global health concern. The aim of this study to determine the frequency and antibiotic susceptibility pattern of S.aureus isolated from wound infected patient attending Wad Madani Teaching Hospitals. Two hundred samples collected from patients with infected wound at the period from April to July 2016. Out of 200 samples examined, 60 (30%) isolates of S. aureus obtained, 116 (58%) other bacterial species and 24 (12%) samples showed no growth. The highest isolation rate of S. aureus 60% occurred among age group (41-60) and according to gender 32 (53.3%) S. aureus isolated from male and 28 (46.7%) from female. The overall profile of susceptibility pattern showed that vancomycin and linezolid were more sensitive (100%), amoxicillin and penicillin were the least sensitive (10%) and (36%) respectively. The result of the study showed that frequency of S. aureus isolated from infected wounds 60 (30%) and vancomycin and linezolid are more effective in the management of S. aureus in this locality.
Growth and flower yield of jasmine (Jasminum auriculatum) as influenced by biofertilizers and graded doses of chemical fertilizers

A field experiment was conducted in an existing three years old jasmine plantation to investigate the effect of biofertilizers on plant growth and yield of Jasmine flowers. The lignite based cultures of Azospirillum, Pseudomonas striata, Pseudomonas fluorescens and Trichoderma viridae were used @ 8 kg/ha each. Results indicated that the biofertiiizer application could substitute the recommended NPK fertilizers to the extent of 50 per cent without affecting various growth parameters, floral characteristics and flower yield.
Analysis of the Vessels’ Service Time in the Port of Gdańsk, Based on the Time Registration of Ships Entries and Departures, as a Proposition of Multi-aspect Method of Port Monitoring

The aim of the paper is to analyse the length of time that ships spend in the Port of Gdansk. It is based on the examination of the time when ships come into and leave the port. Source of data used in the study is public web platform ‐ Marine Traffic. Analysis which was conducted, enables to get information about duration of ships servicing in the port with a division into dimension, load capacity and type of the ship. Due to that information, it is possible to observe the duration of complete service for each vessel, including entering the harbour, reloading and the departure. Gained knowledge would allow to forecast, plan and model future development operations more properly. In addition, due to the method based on counting the number of hours that ships spend in the harbour, it is possible to estimate the amount of pollution emitted to the air. http://www.transnav. eu the International Journal on Marine Navigation and Safety of Sea Transportation Volume 14
Effect of Mood and Worker Incentives on Workplace Productivity ∗

We study the causal effect of mood on the productivity of call-center workers. Mood is measured through an online “mood questionnaire” which the workers are encouraged to ﬁll out daily. We ﬁnd that better mood actually decreases worker productivity for workers whose compensation is largely ﬁxed. The negative effect of mood is attenuated for workers whose compensation is based on performance (high-powered incentives). This ﬁnding holds both at a correlational level and in two IV settings, where mood is instrumented for by weather or, alternatively, by whether the local professional sports team played/won the day before. We rule out a number of threats to the exclusion restrictions, and discuss the mechanisms that could generate our ﬁndings. JEL Codes: J24,
