Re: Questionable Research Conclusions

Questionable conclusions on cannabis and crime.

In a paper published recently in this journal [1], Pedersen & Skardhamar examine whether cannabis users are at increased risk of being charged with criminal offences. They find an association between frequency of cannabis use in one year and risk of criminal charges in subsequent years. The association is statistically significant with respect to drug-specific crime only, and not to other types...

Questionable research practices among italian research psychologists

A survey in the United States revealed that an alarmingly large percentage of university psychologists admitted having used questionable research practices that can contaminate the research literature with false positive and biased findings. We conducted a replication of this study among Italian research psychologists to investigate whether these findings generalize to other countries. All the ...

In Defense of the Questionable: Defining the Basis of Research Scientists' Engagement in Questionable Research Practices.

National Institutes of Health principal investigators reported their perceptions of the ethical defensibility, prevalence in their field, and their personal willingness to engage in questionable research practices (QRPs). Using ethical defensibility ratings, an exploratory factor analysis yielded a two-factor solution: behaviors considered unambiguously ethically indefensible and behaviors whos...

5 Conclusions and Further Re- Search

A novel family of curves was described, which allows to construct arc length parameterized curves between two arbitrary points, with given slopes at the curves' two endpoints. A numerical routine for nding the curves was developed and implemented. Future work may include solving more general problems, such as extending the concepts introduced here to three-dimensional curves. References 1] B. A...
