We conducted an experiment to examine the effect of how subordinates present ideas (constructive vs. complaining form) on supervisor (receiver) responses (perceptions of subordinate intrusiveness and of overall performance). We demonstrated a joint effect of subordinate idea presentation (manipulated) and supervisor dogmatism (measured) such that supervisors with high levels of dogmatism rated subordinates who presented voice constructively as more intrusive and lower in performance than those with low dogmatism. Supervisor perspective taking mediated these relationships. Our findings highlight the importance of presenting ideas in a constructive form to receivers with low levels of dogmatism.

And Task

The study investigated the relationship between access to and use of information and communication technology and task performances of library personnel in public university libraries in South West Nigeria. The total enumeration technique was used to cover 330 library professionals working in public university libraries in the zone. A self-developed questionnaire was used to obtain data. Out of the 330 copies of questionnaire administered 248 (76.6%) copies were found useable. The findings revealed that the level of task performances of the respondents was high, and the level of access to ICT was high, while the frequency of ICT use was moderate. The results indicated that there was a positive relative effect of ICT access and use on task performances. The study also found a significant relationship between the access to ICT, ICT use and task performances of respondents, while there was a significant joint effect of access to ICT and ICT use on the task performances of library personnel. The study recommended the constant development of personnel regarding job knowledge and skills, the promotion of creativity and adaptability skills to enhance personnel task performances, while library managers should continue to make ICT tools accessible for library personnel to allow their use in improving the workflow in the library.

A total of 38 morphometric characters of the round goby Neogobius melanostomus melanostomus (Pallas, 1814) were studied in its native range in the Sea of Azov. The aim was to assess joint effect of sexual dimorphism and size variability on overall variability within groups of samples (populations) using appropriate methods of traditional statistical analysis (one-dimensional and multivariate statistics). Sex and size-dependent variability was studied based on model samples of males and females of different size. Most of the studied morphometric characters of round goby from the Sea of Azov demonstrated statistically significant sex- and size-dependent in-group variability. The pattern of the variability suggests that, for a comparison of round goby from different sea regions and between populations, separate samples of males and females within the range 9–13 cm SL should be examined in order to minimise the effect of the size and sex factors. The approach of searching for the most informative size range could be useful not only for further studies of infraspecific variation but for comparisons between morphologically close gobiin species.

Highly Correlated

The present study explored the relationship between spot and futures coffee prices. The Correlation and Regression analysis were carried out based on monthly observations of International Coffee Organization (ICO) indicator prices of the four groups (Colombian Milds, Other Milds, Brazilian Naturals, and Robustas) representing Spot markets and the averages of 2nd and 3rd positions of the Intercontinental Exchange (ICE) New York for Arabica and ICE Europe for Robusta representing the Futures market for the period 1990 to 2019. The study also used the monthly average prices paid to coffee growers in India from 1990 to 2019. The estimated correlation coefficients indicated both the Futures prices and Spot prices of coffee are highly correlated. Further, estimated regression coefficients revealed a very strong relationship between Futures prices and Spot prices for all four ICO group indicator prices. Hence, the ICE New York (Arabica) and ICE Europe (Robusta) coffee futures prices are very closely related to Spot prices. The estimated regression coefficients between Futures prices and the price paid to coffee growers in India confirmed the positive relationship, but the dispersion of more prices over the trend line indicates a lesser degree of correlation between the price paid to growers at India and Futures market prices during the study period.
