Job embeddedness and employee performance in selected oil and gas companies in Bayelsa state of Nigeria

Despite the relatively high pay employees receive in oil and gas companies in Bayelsa State, some seem not to be happy about the uncertainty in their work environment. This is possibly the reason why the employees in this industry do not look back when they get job offers outside the community. This problem prompted this study on the extent to which job embeddedness correlates with performance of employee in selected oil and gas firms in Bayelsa State. The specific objective of the study is to address the extent to which community fit relates to employee retention. The research question and hypothesis were drafted considering the specific objective of the study. Survey research design was adopted for the study. Two hundred and fifty three was derived as the population, and complete enumeration was used. Data were analyzed with Pearson Product Moment Correlation. The result revealed that there is a significant correlation between community fit and employee retention in the studied oil and gas firms. The study concluded that high job embeddedness which was measured by community fit can help to keep the employees from leaving the organization (employee retention) which was also used to measure employee performance. The study recommends that oil and gas firms in Bayelsa State should focus on community fit as an effective strategy in improving relations between workers and the community to guarantee the retention of the employees. Key words: Job embeddedness, employee performance, community fit and employee retention.
hylogenetic analysis of the calvaria of Homo floresiensis nalyse phylogénétique de la calvaria de Homo floresiensis

Because until 2006 the Liang Bua human fossil remains were not available to the entire paleoanthropological community, the taxonomic position of Homo floresiensis was only a matter of opinion in publications. From the beginning, two schools of thought prevailed, and this situation persists today. One purports that the Liang Bua human series belongs to a local modern human (Homo sapiens sapiens) with anatomical particularities or pathologies that may be due to insular isolation/endogamy. The second argues in favour of the existence of a new species that, depending on the authors, is either a descendant of local Homo erectus, or belongs to a much more basal taxon, closer to archaic Homo or to australopithecines. Because there are no postcranial remains confidently attributed to Homo erectus in the fossil record, and because the Homo erectus type specimen is a single and partial calvaria, a cladistic analysis was undertaken using both nonmetric morphological features and metrics of the calvariae of human fossil specimens including LB1 to test if it belongs to this taxon. Our results indicate that LB1 is included in the Homo erectus clade. © 2016 Académie des sciences. Published by Elsevier Masson SAS.

Study on the bone mineral density of broiler suffering femoral joint degenerative lesions

An experiment was carried out with male and females broilers of two different commercial breeds to evaluate bone mineral density of the right femur head. A number of 600 one-day-old broilers were raised in an experimental poultry house up to 42 days of age at the School of Veterinary Medicine and Animal Science of UNESP, Botucatu, Brazil. After slaughter, three males and three females in each breed in each of the established gross scores were selected. Their femora heads were submitted to gross examination, and subsequently the thighs were submitted to the Veterinary Hospital for radiographic analysis. Femora were also submitted to bone resistance, Seedor index, and dry matter content analyses. All these bone quality characteristics were different between males and females, independent of breed. Breeds presented similar behavior. It was possible to establish correlations between bone quality parameters, and confidence intervals for bone mineral density values, correlating them to femoral degeneration score, which allows characterizing femoral head lesions by radiographic optical densitometry.
Optimization of phenolic compounds extraction with antioxidant activity from açaí, blueberry and goji berry using response surface methodology

The aim of this study was to determine the best extraction conditions of phenolic compounds present in acai, blueberry and goji berry fruits using the response surface methodology (RSM). The phenolic compounds profile by high-performance liquid chromatography, antioxidant activity was also determined. A factorial 23 design was used to analyze the effect of the solvent (ethanol and water), time (30 and 60 min) and temperature (30 °C and 60 °C) on the extraction of total phenolic compounds (TPC) and activity antioxidant (AA). The variables time and temperature had a positive effect on antioxidant activity (AA) in their highest levels, 60 min and 60 °C, respectively. The solvent ethanol 800 g/mL was more efficient in TPC extracting with AA in all matrices. Rutin was present in high amounts in blueberry and goji berry, and the myricetin in acai. The acai showed higher in vitro antioxidant activity when extracted at 60 °C for 60 min. The high correlation coefficient (0.98) of global response (GR) showed that we can find out single and global response in research with multiple dependent variables. The GR analysis indicated the highest values of the TPC and AA when the fruits were extracted at 60°C for 60 min using ethanol as solvent and it was very useful for simplifying and improving the phenolic compounds extraction performance.
Toxicity assessment of chlorpyrifos, λ-cyhalothrin and neem extract against Dysdercus koenigii with reference to survivorship, fecundity and some biochemical parameters.

–The present study was designed to evaluate the comparative toxicity of Chlorpyrifos, Lambda (λ) Cyhalothrin and Neem extract (a bio pesticide) against the adults of D. koenigii. A gradual increase in the mortality was found with the increase of concentration. The calculated LC50 values for Chlorpyrifos, λCyhalothrin and Neem extract were 0.0069%, 0.045% and 0.0787% respectively. The order of efficacy of the three pesticides in respect of toxicity was: Chlorpyrifos > λ. Cyhalothrin > Neem extract. Effect on fecundity of adult D. koenigii was investigated and it is observed that complete egg inhibition occurred at concentrations of 0.0062%, 0.0039% and 0.048% for Chlorpyrifo, λ. Cyhalothrin and Neem extract respectively. This showed that the three pesticides are same in the order of efficacy regarding toxicity and fecundity. Neem extract was found more effective to decrease the total protein content as compared with Chlorpyrifos and λ-Cyhalothrin. Inhibitory effects on GOT (Glutamate Oxaloacetate Transaminase) enzyme were calculated based on Spectrophotometeric analysis and found to be 10.2% (λ-Cyhalothrin) and 4.9% (Neem extract) where as Chlorpyrifos caused an increase in GOT activity up to 1.28% against the survivorship. The overall efficacy of the three pesticides against the survivorship was in the order of Chlorpyrifos > λ Cyhalothrin > Neem extract. This report covers effectiveness of the given pesticides in respect of various biochemical parameters GOT, Protein content, toxicity, fecundity and survivorship against the adults of D.Koenigii. Keywords––Dysdercus koenigii, Toxicity, GOT, Fecundity.
Cognitive functioning in a depressive period of bipolar disorder

Aim of the study. Study aims were to compare neuropsychological functioning of depressed bipolar patients and healthy controls and to estimate relationship between severity of depressive symptoms and cognitive functioning. Method. Cognitive functions were examined in 30 depressed bipolar patients aged 18-68 (M=45,6, SD= 12,6; 18 women and 12 men) who fulfilled ICD-10 criteria for depressive episode (Hamilton Depression Rating Scale score ≥11). The comparison group consisted of 30 healthy subjects aged 23-71 (M=46, 20 women and 10 men) matched in age, years of education and gender to bipolar group. A neuropsychological battery assessed executive functions and working memory. Results. The bipolar patients in depression revealed neuropsychological deficits in working memory and some aspects of executive functions in comparison to healthy group. Only in WCST test both groups received similar results. Neuropsychological functioning seems to be independent of the severity of depressive symptoms. Discussion. Different aspects of working memory and executive functions are impaired in depression period of bipolar disorder and they seem independent of the severity of depressive symptoms. These results are consistent with previous reports. Conclusions. In patients with bipolar depression cognitive assessment should be taken into account in the diagnosis and the disturbances in executive functions and working memory should be treated with neuropsychological rehabilitation and / or pharmacotherapy.
THE EFFECT OF CHEMICAL COMPOSITION OF PEA CONTAINING DIETS ON FEED PREFERENCES BY RATS

The present study was designed to determine the extent in which selected pea seeds constituents, including antinutritional factors, affect the free choice and diet intake by rats. In the experiment in which rats were fed free choice of pea containing diet (400 g/kg) the intake of diet depended on the cultivar inclusion. Diet intake was significantly affected by two variables: protein amount from pea seeds (negative relation) and sucrose content in diet (positive correlation). The other variables which significantly increased sensitivity of multiple regression equation were the content of phenolics, phytates or dietary fibre in diet. Activity of trypsin inhibitors or gross energy of pea seeds had no effect on diet intake.
Combining Ability Analysis for Yield and its Contributing Traits in Maize ( Zea mays L.)

Hybrids were synthesised in a 11 x 11 diallel fashion excluding reciprocals and analysis of combining ability was undertaken for yield and its component traits in maize. Non-additive genetic variance played a preponderant role in the inheritance of plant height, leaf length, number of grains per row and seed yield per plant. Based on general combining ability, parent UMI 757 was found to be a good combiner for improving yield and yield contributing traits. Three cross combinations viz., UMI 852 x UMI 615, UMI 852 x UMI 577 and UMI 852 x UMI 556 had highly significant sea effect for most of the yield contributing traits.

Flame Heights Of Fuel Arrays With Combustion In Depth

Three series of test fires conducted by Factory Mutual Research Corporation in the past, involving deep storages, have been analyzed for flame height, using both video records and temperature measurements on the plume centerline. The test series included 4.5 m high palletized storage of dfierent commodities (13 tests), 3 to 6 In high rack storage of two different commodities (1 1 tests), and wood pallets stacked 0.3 to 3.4 m high (13 tests), all with ignition at the bottom. When flames extended above the storage, their heights were well represented by a correlation for pool fires, referencing the mean flame height to the base of the combustion region (bottom of storage in the present case) and representing the fire diameter as if the fire spreads as a cylindrical volume in the storage (volume spread). An exception was rack storage of a relatively thin, combustible layer (corrugated) over an inert, steel box, comprising a pallet load, for which the fire diameter had to be based on surface spread rather than volume spread. The virtual origin (from which the plume above the flames appears to originate), determined for some of the test fires, appeared predictable from flame height as in pool fires. but requires knowledge of the convective fraction of the total heat release rate, which may not be a constant fraction of the total heat release rate during fire development in the storage.
Portfolio Selection: An Extreme Value Approach

We show theoretically that lower tail dependence (χ), a measure of the probability that a portfolio will suffer large losses given that the market does, contains important information for risk-averse investors. We then estimate χ for a sample of DJIA stocks and show that it differs systematically from other risk measures including variance, semi-variance, skewness, kurtosis, beta, and coskewness. In out-of-sample tests, portfolios constructed to have low values of χ outperform the market index, the mean return of the stocks in our sample, and portfolios with high values of χ. Our results indicate that χ is conceptually important for risk-averse investors, differs substantially from other risk measures, and provides useful information for portfolio selection.
Wellness Tourism: Using Tourists’ Preferences to Evaluate the Wellness Tourism Market in Jamaica

This study sought to evaluate the general wellness preferences of tourists in Jamaica as there is little information to support the body of knowledge on these tourists' wellness preferences in Jamaica and to successfully facilitate segmentation in the wellness tourism market. Jamaica has a naturally appealing environment however; performance in wellness tourism is not among its competitive strengths. Tourists have aligned themselves with the existing tourism offering. A framework is therefore needed to align the push factors of tourists’ wellness expectations with the pull factors of tourism’s offerings. The research examined the tourists' socio - demographic profile, their travel characteristics and the importance of wellness to them. Additionally, it investigated preferred amenities and services, the natural resources associated with particular accommodations, the type of accommodations preferred for a wellness vacation and the locations' attractive attributes. Pre tested survey instruments were randomly administered to two hundred tourists awaiting departure from the island's two international airports. SPSS (version 22) was used to test frequency distributions and percentages, statistical significance and internal consistency. The finding shows that wellness was important however, young people, retirees and higher income earners were not well represented. Strong preferences exist for natural remedies, wellness competencies and mind therapies. Low preferences exist for culinary tours, mineral baths, community involvement and nature experiences. Despite the location's reported physical attractiveness, hotels were preferred for a wellness vacation and many natural and historic features were unexplored. The findings imply that the unique wellness preferences may facilitate ‘new forms’ of tourism and non seasonal tourism niches for small businesses, hotels and rural communities. There may be an alignment with the vocational training system, tourism marketing efforts and international standards. Infrastructural development may also be facilitated around naturally occurring springs, heritage sites, historical buildings and unexplored natural highlights. This emphasis will subsequently support workplace wellness and primary health care.
Latitudinal Distribution and Differentiation of Rice Germplasm: Its Implications in Breeding

To determine genetic differentiation of rice (Oryza sativa L.) across a latitudinal gradient, a total of 386 rice varieties, fi ve African rice varieties, and 52 wild rice accessions mainly from a wide range of Asia were analyzed using insertion and deletion (InDel) molecular markers. Principal component analysis divided rice into two distinct groups, although African rice and wild rice did not show such grouping. Results indicated signifi cant indica–japonica differentiation of rice adapted to a wide range of environments, contrasting with African rice and wild rice. Analysis of the geographic distribution indicated a clear pattern for different types of rice, in which indica varieties were found across a wide range of latitudes from ~2° S to 40° N and japonica mostly limited to latitudes greater than 15° N. Most intermediate types were distributed in regions at latitudes lower than 27° N. Correlation between rice types and temperature along the latitude gradients suggested that indica varieties are less sensitive to temperature along the latitude ranges but japonica varieties are highly sensitive to temperature. The distribution and differentiation of various types of rice across the large latitudinal range is most likely the consequence of their adaptation to ecological and environmental factors, especially temperature. This, together with the accurate determination of indica and japonica types has important implications for hybrid rice breeding through selecting properly differentiated parents.
Why are Canadian Banks More Resilient?

This paper explores factors behind Canadian banks' relative resilience in the ongoing credit turmoil. We identify two main causes: a higher share of depository funding (vs. wholesale funding) in liabilities, and a number of regulatory and structural factors in the Canadian market that reduced banks' incentives to take excessive risks. The robust predictive power of the depository funding ratio is confirmed in a multivariate analysis of the performance of 72 largest commercial banks in OECD countries during the turmoil.
Testing between Competing Models of Sharecropping

The "Marshallian" approach assumes a prohibitively hight cost of monitor ing the sharecropper's activities while the "monitoring" approach a rgues that landlords stipulate and effectively monitor sharecroppers' activities. The author presents new evidence using detailed data col lected from eight Indian villages. Most tenants own some land of thei r own; this provides a controlled environment in studying the impact of contractual arrangements. The differences in input and output inte nsities on owned minus sharecropped land of the same household are fo und to be sizable and significant, suggesting a rejection of the moni toring approach and supporting the notion of the "Marshallian produc tive inefficiency" of sharecropping.

Diagnosing Glaucoma Progression With Visual Field Data Using a Spatiotemporal Boundary Detection Method

Abstract Diagnosing glaucoma progression is critical for limiting irreversible vision loss. A common method for assessing glaucoma progression uses a longitudinal series of visual fields (VFs) acquired at regular intervals. VF data are characterized by a complex spatiotemporal structure due to the data generating process and ocular anatomy. Thus, advanced statistical methods are needed to make clinical determinations regarding progression status. We introduce a spatiotemporal boundary detection model that allows the underlying anatomy of the optic disc to dictate the spatial structure of the VF data across time. We show that our new method provides novel insight into vision loss that improves diagnosis of glaucoma progression using data from the Vein Pulsation Study Trial in Glaucoma and the Lions Eye Institute trial registry. Simulations are presented, showing the proposed methodology is preferred over existing spatial methods for VF data. Supplementary materials for this article are available online and the method is implemented in the R package womblR.
The Life Cycle of Growth Path among Micro Firms: Swedish Data

The main purpose of this study is to empirically examine whether the implications of the life cycle model hold on the growth path of a sample of Swedish micro firms. The study is based on a sample containing 22001 Swedish micro firms across six industries for the year 2007. Several methods are used to analyse the impact of the life stage and two control variables, size and industry, to analyse the impact on firm growth. The empirical results of the study confirm a clear pattern of the growth life-cycle process among Swedish micro firms. Young micro firms, generally, grow on average more than their older counterparts and as they age and develop, their growth rate decreases. Additionally, firm growth among firms of different sizes and in various industries still follows the general pattern of the total sample. Thus, it appears from the results that the growth rate of Swedish micro firms included in the sample follows a systematic and predictable pattern associated mainly with the life stage.
High Growth Firms in Scotland

High growth firms (HGFs) are widely thought to be a key force driving economic growth in modern advanced economies (Acs et al, 2008; BERR, 2008; Henrekson and Johansson, 2010). One of the central aims of the current economic strategy of the Scottish Government is to provide responsive and focused enterprise support to increase the number of highly successful, competitive businesses (Scottish Government, 2007). Hence, for the past decade there have been a number of policy initiatives designed to stimulate high growth entrepreneurship in Scotland. Many of these policies have had a strong technology focus. Given the importance these firms have for a region’s economic growth potential and the policy attention they are beginning to receive, it was felt to be important that Scottish Enterprise develops a deeper understanding of these important generators of wealth creation in the Scottish economy. This report examines HGFs in Scotland from both quantitative and qualitative perspectives.
Effect of particle size of Martian dust on the degradation of photovoltaic cell performance

Glass coverglass and SiO2 covered and uncovered silicon photovoltaic (PV) cells were subjected to conditions simulating a Mars dust storm, using the Martian Surface Wind Tunnel, to assess the effect of particle size on the performance of PV cells in the Martian environment. The dust used was an artificial mineral of the approximate elemental composition of Martian soil, which was sorted into four different size ranges. Samples were tested both initially clean and initially dusted. The samples were exposed to clear and dust laden winds, wind velocities varying from 23 to 116 m/s, and attack angles from 0 to 90 deg. It was found that transmittance through the coverglass approximates the power produced by a dusty PV cell. Occultation by the dust was found to dominate the performance degradation for wind velocities below 50 m/s, whereas abrasion dominates the degradation at wind velocities above 85 m/s. Occultation is most severe at 0 deg (parallel to the wind), is less pronounced from 22.5 to 67.5 deg, and is somewhat larger at 90 deg (perpendicular to the wind). Abrasion is negligible at 0 deg, and increases to a maximum at 90 deg. Occultation is more of a problem with small particles, whereasmore » large particles (unless they are agglomerates) cause more abrasion. « less
