The main purpose of this study is to specify the basic perceptual dimensions underlying the judgments of the physical features which define the style in paintings (e.g. salient form, colorful surface, oval contours etc.). The other aim of the study is to correlate these dimensions with the subjective (affective) dimensions of the experience of paintings. In the preliminary study a set of 25 pairs of elementary perceptual descriptors were empirically specified, and a set of 25 bipolar scales were made (e.g. uncolored-multicolored). In the experiment 30 subjects judged 24 paintings (paintings were taken from the study of Radonjic and Markovic, 2004) on 25 scales. Factor analysis revealed the four factors: form (scales: precise, neat, salient form etc.), color (color contrast, lightness contrast, vivid colors), space (voluminosity, depth and oval contours) and complexity (multicolored, ornate, detailed). Obtained factors reflected the nature of the phenomenological and neural segregation of form, color, depth processing, and partially of complexity processing (e.g. spatial frequency processing within both the form and color subsystem). The aim of the next step of analysis was to specify the correlations between two groups of judgments: (a) mean judgments of 24 paintings on perceptual factors and (b) mean judgments of the same set of 24 paintings on subjective (affective) experience factors, i.e. regularity, attraction, arousal and relaxation (judgments taken from Radonjic and Markovic, 2005). The following significant correlations were obtained: regularity-form, regularity-space, attraction-form and arousal-complexity (negative correlation). The reasons for the unexpected negative correlation between arousal and complexity should be specified in further studies.

Purpose Previous research with children with and without disabilities has demonstrated that visual–perceptual factors can influence the speech of locating a target on an array. Adults without disabilities often facilitate the learning and use of a child's augmentative and alternative communication system. The current research examined how the presence of symbol background color influenced the speed with which adults without disabilities located target line drawings in 2 studies. Method Both studies used a between-subjects design. In the 1st study, 30 adults (ages 18–29 years) located targets in a 16-symbol array. In the 2nd study, 30 adults (ages 18–34 years) located targets in a 60-symbol array. There were 3 conditions in each study: symbol background color, symbol background white with a black border, and symbol background white with a color border. Results In the 1st study, reaction times across groups were not significantly different. In the 2nd study, participants in the symbol background color condition were significantly faster than participants in the other conditions, and participants in the symbol background white with black border were significantly slower than participants in the other conditions. Conclusion Communication partners may benefit from the presence of background color, especially when supporting children using displays with many symbols.

In order to decide which is the best growth model for the tambaqui Colossoma macropomum Cuvier, 1818, we utilized 249 and 256 length-at-age ring readings in otholiths and scales respectively, for the same sample of individuals. The Schnute model was utilized and it is concluded that the Von Bertalanffy model is the most adequate for these data, because it proved highly stable for the data set, and only slightly sensitive to the initial values of the estimated parameters. The phi' values estimated from five different data sources presented a CV = 4.78%. The numerical discrepancies between these values are of not much concern due to the high negative correlation between k and L<FONT FACE=Symbol>¥</FONT> viz, so that when one of them increases, the other decreases and the final result in phi' remains nearly unchanged.

We examined the role that witnesses play in triggering humiliation. We hypothesized that witnesses trigger humiliation because they intensify the two core appraisals underlying humiliation: unfairness and internalization of a devaluation of the self. However, we further propose that witnesses are not a defining characteristic of humiliating situations. Results of a preliminary study using an event-recall method confirmed that witnesses were as characteristic of humiliating episodes as of those that elicited shame or anger. In Experiments 1 and 2, we manipulated the presence (vs. absence) of witnesses when a professor devalued participants and the hostile tone of this devaluation. As hypothesized, in both experiments, witnesses indirectly increased humiliation via the appraisal of unfairness. Results of Experiment 2 revealed that the presence of witnesses also interacted with hostility, enhancing humiliation. As expected, this moderating effect occurred via the other key appraisal of humiliation (i.e., internalization).

The tropical vegetable, brinjal is cultivated throughout the year in Bangladesh but the crop is infested by a number of insects including jassid. This study investigated the effects of different biophysical and biochemical characteristics of twelve brinjal germplasms on the abundance and infestation of jassid. The experiment was conducted during September 2018 to March 2019 in Gazipur, Bangladesh with twelve brinjal germplasms namely BD-7320, BD-7328, BD-9952, BD-10154, BD-10158, BARI Begun-1, BARI Begun-4, BARI Begun-5, BARI Begun- 6, BARI Begun-7, BARI Begun-8 and BARI Begun-9. The incidence of jassid was recorded from 3rd December to 26th March, and the lowest population was found on BARI Begun- 6. Among the biophysical traits, plant height, number of branch and leaf per plant, and leaf area exerted significant positive correlation; whereas trichome on lower and upper surfaces of leaf, spine per stem and leaf showed significant negative correlation with the abundance of jassid. On the other hand, moisture, reducing sugar, total sugar and protein content of the leaves and fruits, chlorophyll content of the leaves exerts significant positive correlation but ash and pH contents of the leaves and fruits were negatively correlated with the abundance of jassid. Jassids showed the lowest level of leaf infestation on BARI Begun-6, which could be for further analysis to develop jassid resistant brinjal. SAARC J. Agric., 19(1): 81-91 (2021)

With the publication of the article ‘Cycles in symbol production’ (Peterson and Berger 1975) a discussion started concerning the advantages and disadvantages of the production of cultural goods under market conditions. The analysis by Peterson and Berger showed a negative correlation between concentration in the recording industry, on the one hand, and the diversity and innovativeness of the music, on the other. Repetition of the analysis using data from the 1980s (Burnett 1990; Lopes 1992) has shown that for this period Peterson and Berger's hypotheses should be rejected. Is there a connection between concentration and diversity and innovation? Are there cycles in symbol production? There seems to be no conclusive answer. In this article, I will attempt to clear up this matter. First, I will repeat the analysis of the relation between concentration and diversity/innovation, using the same model as Peterson and Berger, but with different definitions for the variables concentration, diversity and innovation. Then I will suggest a new model, which can be helpful in uncovering other factors influencing diversity and innovation in the music industry. I will come to that later. Let me first give the reader a brief overview of previous research.

This paper examines the nature, impact, effectiveness and barriers of e-government in the Federal Government of Nigeria. It also explores the extent to which e-government has facilitated a better relationship between citizens and the federal government of Nigeria. It argues that the utilization of technologies such as internet, email, websites, and social media have yet to effectively connect citizens, and the government. As a result, the federal government of Nigeria has not fully adopted the new e-government approaches to improve its services. The paper uses data derived from questionnaire survey administered to 3,000 Nigerian citizens including federal government staff in Abuja, Lagos and some state capitals in Nigeria., Interviews of 300 federal officials and stakeholders were conducted. The secondary data consisted of the review of related government reports, government websites, academic and professional journals. Data were analyzed to determine the impacts of e-governance in the federal government. The conceptual framework is based on stakeholders’ theory, and an integrated e-government model. The findings suggest that on one hand there is a negative correlation between the e-governance initiatives and federal government efficient service delivery in Nigeria. On the other hand, there is also a negative correlation between citizens and federal government relations in the country. Some challenges preventing the adoption of proactive e-governance practices were identified and recommendations for appropriate policies that could address the current impediments were offered.

Objectives: Studies have shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is primarily transmitted from person to person via airborne droplets. It is unclear whether it can be shed into human milk and transmitted to a child via breastfeeding.We investigated the presence of SARS-CoV-2 RNA in human milk samples of 15 mothers with coronavirus disease 19(COVID-19) and in the throat swab samples of their infants. Methods: This is a prospective observational study in which breast milk samples were collected from 15 mothers with COVID-19. The presence of SARS-CoV-2 RNA in the whole human milk samples of the patients was investigated using RT-qPCR. All of the infants underwent a clinical follow-up during their 14-day isolation and their throat swab samples were tested for SARS-CoV-2 RNA. Results: Of 15 mothers with COVID-19, SARS-CoV-2 RNA was detected in milk samples from 4 mothers. The throat swab samples from these mothers’ infants were found to be positive for SARS-CoV-2 RNA. Three of the four mothers were breastfeeding. In addition, during the 14-day isolation, all but three of the mothers breastfed their infants. Of the 12 breastfed infants, while the test for SARS-CoV-2 RNA in throat swab samples was negative in six of the infants, the other six infants, who had mild COVID-19 symptoms, tested positive for SARS-CoV-2 RNA.Clinical outcomes of all mothers and infants were uneventful. Conclusion: To our knowledge, this is the first case series with the largest number of cases with SARS-CoV-2 RNA positivity in human milk samples of mothers with COVID-19. However, we believe that the benefits of breastfeeding may outweigh the risk of SARS-CoV-2 infection in infants

Confidence in astrology remains a visible phenomenon in contemporary society, and this is a constant topic of academic interest. A survey based on 512 valid questionnaires were obtained from a non-probability sample of university students from Bucharest, in order to observe possible statistical relations between confidence in astrology, confidence in sciences such as medicine and mathematics, but also fields such as astronomy and horoscope. On the other hand, several statements have been used to measure the level of religiosity. Notable is the moderate positive correlation obtained between astrology and astronomy, but also the strong correlation between astrology and horoscope (this last correlation was expected). Broadly speaking, it is observed that astrology correlates positively with the variables that constitute the ‘inward’ component of religiosity, while the ‘outward’ component shows a rather negative correlation, but which does not enjoy a similar statistical significance. Astronomy, like medicine, outlines negative relation with the level of religiosity. Instead, the correlations that involve trust in medicine have a negative and moderate value, in relation to religiosity. In conclusion, it is observed that the trust in “strong sciences” generates more prompt correlations compared to the trust in astrology, while further studies are needed to clarify the reasons for such uncertain correlations between astrology and religiosity.

Studies were conducted at the Fortuna Substation for 10 years to determine the effect of 5 interstems on growth and yield components of 2 commercial mango varieties. The interstems did not significantly affect the rootstock diameter when Edward variety was the scion; however, they did with Palmer variety as scion at the 3- and 6-year stages only, Irwin interstem diameter at the 3-year stage for Edward and Palmer, and at the 6- and 9-year stages for Edward, was significantly thicker than that of the other interstems. Edward on Manzano Tetenené had the thinnest interstems. In the two varieties studied, the scion diameter was scarcely affected by the interstems at 3, 6 and 9 years after transplanting. Edward and Palmer grafted on Irwin as interstems had significantly lower scion/interstem ratios. The opposite was true when these varieties were grafted on Julie. Three years after planting, the smallest trees were those of Edward and Palmer grafted on Malda; 6 and 9 years after planting, those of Edward grafted on Malda and Manzano Tetenené. Yield efficiency decreased significantly with tree age and size. Thus, there was a negative correlation between these parameters. Edward produced significantly more fruits than Palmer at the 3-year-old stage. Edward as interstem grafted on Eldon produced significantly more fruits at the 3-, 6- and 9-year stages than when grafted on the other interstems. Palmer grafted on Eldon was significantly more precocious than when grafted on the other interstems. Malda and Manzano Tetenené as interstems significantly reduced tree size of Edward; Julie as interstem reduced the size of Palmer.
