Abstract
This paper aims to replicate 148 anomalies and to examine whether the performance of the Korean market anomalies is statistically and economically significant. First, the authors observe that only 37.8% anomalies in the universe of the KOSPI and the KOSDAQ and value-weighted portfolios have t-statistics that exceed 1.96. When the authors impose a higher threshold (an absolute value of t-statistics of 2.78), only 27.7% of the 148 anomalies survive. Second, microcaps have large impacts. The results vary significantly depending on whether the sample included stocks in the KOSDAQ and whether value-weighted or equal-weighted portfolios are used. The results suggest that data mining explains large portion of abnormal returns. Any tactical asset allocation strategies based on market anomalies should be applied very cautiously.

Abstract
Purpose
Cannabis use continues to increase worldwide, and a number of nation states are changing their cannabis policies. Policy changes require research into key populations, namely, people who use cannabis. This study aims to examine sociodemographic differences of young Finns who reported using cannabis mainly for self-medication versus mainly recreationally, as well as their reported effects of cannabis use.
Design/methodology/approach
The data come from an anonymous online survey (N = 247, 70.0% males, 25.9% females, 4.1% other) that was analysed using multiple logistic regression. The authors focused on whether various demographic indicators differed between those who reportedly used cannabis mainly for recreational purposes and mainly for self-medicinal purposes. The authors also qualitatively examined the respondents’ experienced effects of cannabis, both desired and undesired.
Findings
Being older and female, living in a smaller city and earlier age of initiation of cannabis use were statistically significant in predicting the medicinal use of cannabis. The majority of recreational effects were related to themes such as relaxation and pleasure, but many participants also reported desired medical effects. Similarly, many participants reported several undesired effects.
Research limitations/implications
Understanding especially young people’s motivations to use cannabis, which include using it for various medical effects, can improve the design of harm reduction and treatment programmes as well as enhance the well-being of people who use cannabis.
Originality/value
This study gives a nuanced account of sociodemographic factors and motivations of young people who use cannabis in Finland as well as the reported effects it has on them, which complements data from national drug surveys.

Abstract
Purpose
The purpose of this paper is to increase knowledge of the role organizational factors have in how health personnel make efficiency-thoroughness trade-offs, and how these trade-offs potentially affect clinical quality dimensions.
Design/methodology/approach
The paper is a thematic synthesis of the literature concerning health personnel working in clinical, somatic healthcare services, organizational factors and clinical quality.
Findings
Identified organizational factors imposing trade-offs were high workload, time limits, inappropriate staffing and limited resources. The trade-offs done by health personnel were often trade-offs weighing thoroughness (e.g. providing extra handovers or working additional hours) in an environment weighing efficiency (e.g. ward routines of having one single handover and work-hour regulations limiting physicians' work hours). In this context, the health personnel functioned as regulators, balancing efficiency and thoroughness and ensuring patient safety and patient centeredness. However, sometimes organizational factors limited health personnel's flexibility in weighing these aspects, leading to breached medication rules, skipped opportunities for safety debriefings and patients being excluded from medication reviews.
Originality/value
Balancing resources and healthcare demands while maintaining healthcare quality is a large part of health personnel's daily work, and organizational factors are suspected to affect this balancing act. Yet, there is limited research on this subject. With the expected aging of the population and the subsequent pressure on healthcare services' resources, the balancing between efficiency and thoroughness will become crucial in handling increased healthcare demands, while maintaining high-quality care.
