Purpose Intrapreneurship is rapidly concerning organizations to tailor their operations and strategies for competitive advantage. Research on intrapreneurial dimensions is in the developing stage, requiring more rigorous methods of investigation and application in various contexts. This study aims to focus on individual level intrapreneurship by examining the association of personality traits (PTs) on intrapreneurial behaviour (IB) moderated by knowledge sharing behaviour (KSB) and comparison of employees in engineering and functional departments. Design/methodology/approach A survey has been conducted for data collection using a structured questionnaire. Partial least squares structural equation modelling has been used for hypotheses testing, moderation and multi-group analysis on a sample of 534 respondents. Findings Results reveal that PTs exerted a positive influence on IB. The impact of PTs on IB was more pronounced in the employees of functional departments. KSB moderates positively in the relationship between PTs and IB. Both groups significantly differ in dimensions of PTs. Practical implications Organizations can do little to improve PTs of employees, which impacts on intrapreneurship in organizations. However, KSB in organizations can be improved by adopting various measures. KSB eventually promotes innovation in organizations resulting in an overall competitive advantage for firms. Originality/value This is the first study that contributes theoretically in intrapreneurship literature by providing insights on PTs impacting IB incorporating KSB and comparing the diverse group of employees.

The present study is aimed at analyzing the effects of peer tutoring on the academic achievement of students in the subject of biology at secondary level. The objectives of the study were: (1) To find out the effects of peer tutoring on the academic achievement of students in the subject of biology; and (2) To examine the effects of peer tutoring with respect to knowledge, comprehension and application levels in cognitive domain of Bloom Taxonomy. All 433,405 male students at secondary level of 10th grade of Khyber Pakhtunkhwa were the population of the study. Forty students were taken as the sample of the study from the Allied National Software Institute (ANSI) Mardan. The Posttest-Only Equivalent Group Design was used. The data collected from pretest and posttest were analyzed through an independent sample t-test. It was found that the mean score of the experimental group was significantly better than that of the control group. It was concluded that peer tutoring enhanced the academic achievement of students in the experimental group significantly as compared to the control group; hence, it was an effective method of instruction for teaching biology at secondary level. It was suggested that peer tutoring may be incorporated along with other teaching methodologies for the subject of biology and it may be given due consideration in all teacher education practices in the country.

Background: Date pits although being rich in phenolic and antioxidant content are neglected part and treated as waste product. Ethanobotanical records indicates potential of ajwa dates pits and flesh having phenolics, antioxidants and some other nutrients.Objective: The study was planned to extract the phenolic contents and antioxidant activity of ajwa date flesh and pits in comparison to local date varieties, in three different solvents with three different concentrations and to observe their effect on high lipo-protein profile of albino mice.Materials and Methods: Three solvents viz. Methanol, Ethanol and Acetone was used at concentration of 70%, 80% and 90% to make nutraceutical extracts. These extracts were characterized for numerous nutritional parameters.  Correlation of flavonoid with phenolic, DPPH, and ABTS and other parameters were studied. The above extracted ajwa flesh and pits extracts were then administrated to high cholesterol induced albino mice under three different treatments (10%, 20% and 30%) in four different groups where one group was studied as control.Results: Pits appeared as significantly richest source for total phenols, total flavonoid contents. Such extracts from pits were high in DPPH and ABTS activity as compared to flesh in all date cultivars being highest in ajwa pits (3932.3 mg GAE/100g, 2956.2 mg QEC/100g, 96.3% and 86.2% respectively). In comparative analysis of solvents, 80% ethanol extracted highest antioxidant activity for both DPPH and ABTS assay in all date varieties and their parts. Behavior of solvent for polyphenols (Total phenols and total flavonoids) extraction was highly variable so that a single solvent cannot be recommended for extraction. Highly significant correlation of flavonoids with DPPH was observed in pits part. Phenolic contents positively correlated with flavonoids, DPPH and ABTS. DPPH and ABTS also revealed strongly positive increasing correlation. In PCA analysis phenolic contents, flavonoid contents and antioxidant activity showed a closeness in case of pits while showed weak relation in flesh parts.  Furthermore, results also depicted that 30% extracts of ajwa pits have higher effect on percent reduction of total protein, total triglycerides, total cholesterol and LDL-C levels while also significantly increased the percent HDL-C levels in treated albino miceConclusion: The work identifies variability among flesh and pits of ajwa date and local date varieties for their polyphenols contents and antioxidant activity and their health beneficial effect against high Lipo-protein profile that can be used as an active ingredient against different maladies in food products and supplements. Key words: Ajwa, Phenolics, antioxidants, PCA
