Appropriate number of analogues in analogy based software effort estimation using quality datasets
Analogy-based software effort estimation (ASEE) plays an important role in software development. It attracts the attention of researchers nowadays due to the simplicity of the ASEE reasoning method. ASEE reasoning is considered simple because it is similar to human reasoning. The estimation approach repeatedly uses the effort values of preceding similar projects. In this approach, the appropriate number of similar previous projects to be reused is still a topic of debate in ASEE research studies. The reliability and accuracy of ASEE methods are considerably affected by the quality of software repositories (datasets). Therefore, if a software dataset does not follow the ASEE principle, then it is not considered useful for the ASEE method. This article presents a novel approach for ASEE to find the appropriate number of analogues from quality datasets. In this approach, the data pre-processing stage is based on Spearman’s rank-order correlation and Kruskal–Wallis test. In the proposed approach, it can deal with categorical (both nominal and ordinal) attributes individually. Spearman’s rank-order correlation is used to find reliable numerical and ordinal attributes. Kruskal–Wallis test identifies reliable nominal attributes. Reliable attributes refer to those attributes which significantly influence the effort. The experimental results show that the proposed approach enhances the quality of the dataset, attribute selection from the metadata, and reduces the abnormal observation and overall project development cost.

Ambidexterity and performance in multiunit contexts: Cross-level moderating effects of structural and resource attributes
Research suggests that unit-level ambidexterity positively impacts subsequent unit performance but theory and testing on this impact remain impoverished. We develop a cross-level model suggesting that structural and resource attributes of the organizational context significantly shape the relationship between unit ambidexterity and performance. Using multisource and lagged data from 285 organizational units located within 88 autonomous branches, results from hierarchical linear modeling show that this relationship is boosted when the organization is decentralized, more resource munificent, or less resource interdependent. We also find that structural differentiation of the organization does not condition the unit ambidexterity-performance relationship. Through this cross-level theory and testing, we develop a richer explanation of the effectiveness of ambidextrous units operating in multiunit contexts.

The story of God : a biblical comedy about love (and hate)
\"Part Kurt Vonnegut, part Douglas Adams, but let's be honest, Matheson had me at 'Based on the Bible.'\" --Dana Gould, comedian and writer The Bible offers some clues to God's personality--he's alternately been called vindictive and just, bloodthirsty and caring, all-powerful and impotent, capricious and foresighted, and loving and hateful. But no one has ever fully explored why God might be such a figure of contrasts. Nor has anyone ever satisfactorily explained what guides his relationship not just with angels, the devil, and his son, but also with all of creation. Might he be completely misunderstood, a mystery even to himself? Might his behavior and actions toward humankind tell us much more about him than it does about us? Enter the mind of the creator of the universe, travel with him through the heavenly highs and hellish lows of his story, from Genesis to Revelation, to better understand his burdensome journey: being God isn't easy. After hearing his story--at times troubling and tragic but always hilarious in its absurdity and divine in its comedy--you'll never look at a miracle or catastrophe--or at our place in the universe, or God's--the same way again\"-- Provided by publisher.

Do corporate attributes impact integrated reporting quality? An empirical evidence
Purpose
This study aims to examine the impact of corporate attributes on integrated reporting quality of top 100 listed firms in South Africa.
Design/methodology/approach
With a sample of the top 100 listed firms in South Africa, this paper drew insights from the legitimacy and stakeholder theory to examine the impact of corporate attributes on integrated reporting quality. This paper measured integrated reporting quality based on the International Integrated Reporting Council framework of 2013. Corporate attributes were determined taking into consideration three broad perspectives (board committee attributes, firm attributes and audit committee attributes). This paper analyzed the data using content analysis, ordered probit regression and logistic regression method.
Findings
Results indicate that board committee attributes, firm attributes and audit committee attributes have a positive and significant relationship with integrated reporting quality. Additional analysis reveals that external assurance contributes to the quality of integrated reporting. The findings empirically revealed that most South African firms have intensified efforts toward the quality and full disclosure of integrated reporting framework.
Research limitations/implications
The study was limited to a sample size of 100 firms, which is country-specific, however, it sets the tone for future empirical research on the subject matter. This study provides an avenue for future research in the area of corporate attributes and integrated reporting quality in other emerging countries, especially other African countries.
Practical implications
The result of this study provides practical implications in the areas of good corporate governance, corporate reporting and integrated reporting. The empirical approach used in this study emphasizes the need for corporate organizations to introduce integrated reporting practices into their reporting cycle. The finding implies that non-compliance with integrated reporting by corporate organizations may have an adverse effect on corporate growth, corporate sustainability and corporate reputation in the long run.
Originality/value
The work extends prior research on the subject of integrated reporting in South Africa. Also, this study broadens the application of legitimacy and stakeholder theory in influencing corporate organizations to disclose relevant information that could aids stakeholders’ interest.

Beyond teaching: exploring students’ preferred academic and personal attributes in university educators
This study examines students’ perceptions of preferred academic and personal attributes of favored university educators. An online survey was conducted by asking undergraduate and graduate students from public and private universities in Jordan, which yielded a total of 1,111 responses. It was found that students highly valued faculty members who possess academic attributes such as enthusiasm and the use of creative teaching methods, and in personal attributes, they preferred respect and empathy. Additionally, based on institution type and academic performance, significant differences were observed, with students from public universities and high-achieving students showing a greater appreciation for faculty attributes. However, based on course grade level, no significant differences were found. These findings underscore the importance of aligning faculty development with student expectations in higher education institutions. This study suggests integrating training programs that focus on emotional intelligence, as well as innovative pedagogy, to maintain student engagement and improve learning outcomes. By creating a teaching environment that strikes a balance between academic excellence and strong interpersonal connections, universities can enhance student satisfaction and overall educational experiences.
