Abstract
Purpose
Ever since the publication of the original Jegadeesh and Titman (1993) study, momentum effect has been tested vigorously to validate its pervasiveness for different time periods and across different markets. In spite of numerous out-of-sample tests, there is one apparent alibi – little research has been devised for steady increasing of Shari’ah compliant stocks.
Methodology/approach
This study is to examine the momentum strategy returns in a global Shari’ah compliant stock setting.
Findings
It finds strong presence of stock momentum returns for Pakistan and Malaysia. And the momentum returns are neither driven by industry momentum nor by the small size stocks. Though no momentum profits are found for the portfolios formed by global Shari’ah compliant stocks, this seems to be largely due to return reversal for the small size Shari’ah compliant stocks.
Originality/value
The strong presence of momentum profits for relatively large Shari’ah compliant stocks is a desirable trait as it indicates that the momentum trading strategies are practical and implementable.

Abstract
The German evidence-based model of educational governance is bureaucratically regulated, but teachers and schools are autonomous in their way of implementing requirements in schools. Accountability is ensured by regularly monitoring educational outcomes with reference to national educational standards, e.g. in the form of mandatory comparative performance tests. In this context, it is worth determining the process stages of research engagement with which the available data or evidence is associated and which purposes they can serve in teacher education and practice. Building on that, an overview is provided of the state of (mainly German) research on teachers' and school leaders' research engagement and influencing factors. This research field has flourished in the wake of the Empirical Shift in German education. By now the understanding has emerged that ultimately the depth of inferential processes is vital for sustainable development and this in turn is influenced by data, context and user characteristics. On the individual level, in particular, positive affective-motivational dispositions and research literacy are deemed important, whereas the feeling of being controlled has detrimental effects. On the school level, school culture and leadership are of impact, whereas a certain continuity of measures on the governance level proves meaningful for the engagement with data and evidence in educational practice. With regard to the German experience, it is concluded that more (funded) dialogue opportunities between different actors and professional groups in education are needed and that initial and further training should strive even more to impart a meta-reflective stance or enquiry habit of mind.

Abstract
The overall goal of science is to build a valid and reliable body of knowledge about the functioning of the world and how applying that knowledge can change it. As personnel and human resources management researchers, we aim to contribute to the respective bodies of knowledge to provide both employers and employees with a workable foundation to help with those problems they are confronted with. However, what research on research has consistently demonstrated is that the scientific endeavor possesses existential issues including a substantial lack of (a) solid theory, (b) replicability, (c) reproducibility, (d) proper and generalizable samples, (e) sufficient quality control (i.e., peer review), (f) robust and trustworthy statistical results, (g) availability of research, and (h) sufficient practical implications. In this chapter, we first sing a song of sorrow regarding the current state of the social sciences in general and personnel and human resources management specifically. Then, we investigate potential grievances that might have led to it (i.e., questionable research practices, misplaced incentives), only to end with a verse of hope by outlining an avenue for betterment (i.e., open science and policy changes at multiple levels).
