[ODP] Crime, income and employment among immigrant groups in Norway and Finland

#11
I cannot find anything wrong with this paper. I approve publication. My only quibble is that it should be a brief communication, as it doesn't add a new perspective compared to the papers the author has previously published, but it simply extends them.

Brief communication is fine with me. I wanted to keep it short and to the point, given that it's just new data, not new theory.

I approve. The following is a list of suggested corrections:

Page 1, line 1 - replace "prediction analyses" with "predictive analyses"
Page 1, line 8 - replace "socioeconomic variables" with "socioeconomic traits" or "socioeconomic attributes"
Page 1, line 11 - replace "theoretic" with "theoretical"
Page 1, lines 12-13 - replace with "a country's performance on a variety of variables is to some degree due to the average psychological makeup of its inhabitants"
Page 1, line 14 - replace "degree which will be reflected" with "degree, as reflected"
Page 1, line 16 - replace "cause" with "determine"
Page 1, line 18 - delete "e.g." (this is redundant because you already wrote "For instance")
Page 1, lines 20-21 - you might want to mention some of these other attributes, e.g., time preference, impulse control, anger threshold, monotony avoidance, affective empathy, etc.
Page 1, lines 24 and 25 - replace "Somalians" with "Somalis". The entire sentence could be rewritten as:
"Somalis living in Denmark are far richer than those who have stayed behind in Somalia, but they are nonetheless poorer than ethnic Danes, just as Somalia is poorer as a whole than Denmark."

Page 2, figures 1 and 2 - delete "groups"
Page 2, lines 2 and 3 - replace "tend to be criminal" with "are similarly predisposed to criminal behavior."
Page 2, line 5 - replace "was useful" with "could be useful"
Page 2, line 6 - replace "must concern" with "must inform us about"
Page 2, line 7 - replace "for" with "on"
Page 2, lines 7-8 - replace with "with a large enough sample of countries, i.e., more than 10"
Page 2, line 11 - correct the spelling, i.e. "datasets"

Page 3, line 4 - replace "in percent" with "as a percent"

Page 5, line 2 - replace "is available" with "are available" and add an 's' to "source code"

References - go through the references and capitalize proper nouns, e.g. "Denmark", "Danish", "Norwegian", etc.

The lack of capitalization in the references list is a LATEX feature (it strips it as a feature). However, we found a way to get around it. http://tex.stackexchange.com/questions/1...g-bbl-file


You will have to post a version without a water mark if you want a more thorough commentary.

1. Rewrite the Abstract e.g., "[The] results", "their nation or origin [characteristics]", "I
present new [finding] regarding [rates] of crime, income ... for different immigrant [groups decomposed by nation of origin]."
2. In P1, "This study is a step in that direction"; Also please cite the Danish happiness paper e.g., "see also [4]."
3. In P2, "The psychological attributes of the individuals living" ("People" can refer to the collective attributes)
4. In p2 "Which will be reflected on outcome measures such as psychological tests or SES indexes" (it's not just tests).
5. In P4. "are low in the relevant behavior traits" (Don't pigeon hole the theory.)
6. In p4. How about: "The STH doesn't specify a cause for the national group differences; these could be due to cultural or other factors. This hypothesis also allows migrant absolute performance to increase; it merely predicts that migrants will carry with them certain national differences because these differences represent or result from temporally stable behavioral ones at the individual level. To be clear, this need not be the case. Measured national differences could be due to psychometric bias or they could be group level phenomena. For example, national differences in crime rate or in Happiness might be due to interactive factor in the nation of origin that can't be carried along by migrants by virtue of being on the national level."

7. In P7, "To be useful, the data must [include].

"Tertiary educational attainment per capita for persons aged 16 and above in 2013.5 This table was in absolute numbers so I supplemented it with [the] population size by country of origin to calculate a pseudo per capita value."

"This introduces error if [the national population age and migrant group age structures are different.]"

rewrite "the bad performance of Antinok" e.g., "The poor predictive power of Antinok et al.'s national achievement scores seems to have been largely due to sampling error."

rewrite: "Figures show three plots". e.g., "The figures below show plots for ... "

...

No conclusion? Give at least a couple of sentences.

"This study has replicated and extended results of previous studies. More support for the STH with regards to X,Y, and Z has been found. On the international level X,Y, and Z have been found to be .... "

Why need for conclusion ? It's just a replication, as explicited in the intro. He gave the references for previous studies, so people can look at them and read the discussion section from these papers, no ? I don't think it needs conclusion if the purpose is to rewrite what has been written in previous articles.

If that's kosher here, so it is. It just strikes me as being odd. Can you show me a replication study published elsewhere that doesn't have a conclusion/discussion? That's what mean.

Emil, can you make the corrections mentioned? Let's get this process moving along.

Yes, I will make the corrections. I will also add some notes about limitations. Most of the datasets are not age and/or sex corrected, which introduces error.

You can just copy the text from the source file (article.tex). The reason to use the draft watermark was discussed here: http://www.openpsych.net/forum/showthread.php?tid=119


Have you tried copying text from the watermarked pages? Very annoying. How about you just write DRAFT at the top of the first page?

Quote:
Quote:2) Figures 1 and 2 are under copyright and probably cannot be used under fair use.

The journal is hosted in Denmark and from my reading of the Danish copyright law, it is clearly a legal case of quotation.

I wouldn't be sure of that, but it's your call. I don't think the figures are necessary.

Quote:
Quote:6) "the sample of countries was not so large as to introduce significant sampling error in estimates."

Clarify why increasing N increases sampling error.

It is indirectly mentioned earlier: "The first variable includes all groups with a population $>=200$. The second only includes groups with $>=1000$ such as to reduce sampling error."

Including many countries means the samples must be smaller. This introduces sampling error.

Yes, I understand that but it's poorly explained in the paper. You should mention the sample size problem again when talking about the second "condition" for adequate predictions.

Quote:I used Table 2 data, yes.

Adjusting for sex and age statistically overdoes the adjustment. If you look at their Table 4, M2 (age+sex adjust in logistic regression) has a rate of .7 for Afghans in Norway, lower than natives (1.0). That's not right. Afghan men aged 20-29 do not have lower crime rates than Norwegian men aged 20-29. (Looking at women is uninteresting since they commit only 10% of crimes or something).

The Danish dataset allows one to examine the effects of statistically controlling for age and sex while also doing it manually (by limiting the sample to men in some age group).

What one want to do is compare similar age groups as I did in the Danish study. I have asked SSB (Norway Statistics) for these data: men, age 15-19, 20-29, per capita crime rates by country of origin. It may take some time for them to give it to me. It may cost a lot of money. Basically, SSB is given a government monopoly on access to the data, so they can set the prices any way they want.

Perhaps they will give me the data soon, then we can compare the statistically adjusted values with the real ones.

Without adjustment for sex + age your estimates are biased in favor of the spatial transferability hypothesis. So if you cannot adjust your estimates for this, you should at least emphasize in the paper that the results are questionable because of this.

Quote:I did some MR analyses, but it didn't seem very interesting, so I left it out.

I used automatic modelling in R, using AIC and BIC. AIC results always included Islam and some at least one of the others. BIC always resulted in the model of Islam+GDP. This was also the result in my previous Danish study when I compared adjusted R^2 values.

Automatic modeling seems iffy especially with such limited data. I think you should report at least predictor intercorrelations and selected, theoretically sensible MR results.

Dear reviewers,

I have made significant findings using the datasets and it will necessitate heavily expanding the paper. Briefly, I used factor analysis to find an S factor among the groups (yes it is there), quantified the strength of it using multiple measures (very strong), calculated the cors with predictors and the S factor (pretty high, IQ -0.69, Islam 0.81, GDP-0.45, International S -0.68), and correlated the vectors of cors of each predictor with each other to see if the same variables were highly/not very highly predictable using different predictors (they were, cors around .9).

I ran FA using complete cases (N=15), which is known to be suboptimal. I will look into better ways to impute missing data.

And before that I discovered that I had made huge errors in inputting the data from Skardhamar. I have now fixed this, altho it did not change results that much. I used the sex and age adjusted data.

Various small changes to language (e.g. added sample sizes to the introduction of the datasets).

A new expanded draft will follow shortly, 1-3 days.
