Eroticizing others– what do the majority men want to see in minority women?
It is their breasts which represent the ‘nature’, a nature that needs to be conquered.
Tourists, amateur photographers go ‘hunting’ for ‘mountainous women in streams’.Tourist websites eagerly promote this ‘cultural heritage’, together with exotic ‘minority alcohol’ to attract (male) customers.
Common words used to describe them : ‘mountainous girls’, ‘wildly beautiful’, ‘innocent’…
Drunkenness in northern upland of Vietnam
- The state/tourist industry: it is cultural heritage of ethnic minorities, it is simply ‘beautiful’
- The public health official: it is a health risk – lack of knowledge, lack of information
- The sociologist: it reflects societal problems – power inequality, shortage of employment opportunities, discrimination against ethnic minorities, problems of internal colonialism
- The anthropologist: it functions to help drinkers overcome something, inside (a psychological, temporal escape of inescapable social inequalities) or outside their heads (smoothing social relations, building social networks, etc)

Guanxi, Blat: the economy of shortage
In command economies of Soviet countries, China, and Vietnam, foods and services were often scare.
The practice of getting scare services and goods from informal contacts was widespread. In Chinese, it is called, in general sense, guanxi. In Russia, it is blat. Many other academic terms relates to that:
‘economy of favours’, ‘economy of shortage’, ‘second economy’, ‘culture of shortage’
How have those practice changed over time and how could they be used for analyses of contemporary social issues in the post-socialist countries are important questions.
People have said much about ‘social capital’ and often ignored this form of social capital in the post-socialist world.
This is a good review, it is worth having a look:

Power Analysis for multiple logistic regression
II – Long answer:
powerlog, p1(.25) p2(.35) rsq(.4)
In order to understand that, you should think of a ‘dependent variable’, ‘key predictor’, and all other predictors which are of less interest, or confounders.
p1 and p2 concern the key predictor and the dependent variable (Y) only:
- at p1, you guess the possibility of Y=1 if p1 is at its mean
- at p2, you guess the possibility of Y=1 if p1 is at its mean plus one standard deviation (or p1=mean+1 SD)
rsq concerns only the key predictors and all other predictors. Ideally there should be no endogenous variable in the set of predictors – or rsq should be 0. If you expect some level of correlation between the key predictor and other predictors, note that:
- strong correlation: 0.5 to 1
- moderate correlation 0.3 to 0.49
- weak correlation 0.1 to 0.29
In the case above p1 is set at 0.25 and p2 at 0.35. That means when the key predictor takes its mean value, the possibility that Y=1 (eg. getting promoted, getting cancer, being an alcohol abuser) is 0.25. Note that when p2 is set at 0.35, the expected association between Y and key predictor is a positive one – when key predictor increase, the change of getting Y=1 increases.
In Stata we get 290 for power=.80

Note that this is a power analysis for one-tailed test, which mean 5% chance of ‘wrong guess’ goes all on one tail of the curve:
For a two-tailed test, each tail would have a 2.5% chance that the guess would go wrong
In stata, we can do as below. This time we get 369 for power=.8, two tailed.

Dealing with Survey data (updating)
2) Think about research goals: Do you want to compare something with something else, or do you want to see if something relates to something else?
3) Choose the test, as mentioned here
4) Read the questions and answers as following (credits UCLA):
- How do I use the Stata survey (svy) commands?
- Sample setups for commonly used survey data sets
- Choosing the correct analysis for various survey designs
- How can I check for collinearity in survey regression?
- How can I do a t-test with survey data?
- How can the standard errors with the cluster() option be smaller than those without the cluster() option? (from Stata FAQs)
- Do the svy commands handle zero weights differently than non-svy commands? (from Stata FAQs)
- How can I analyze a subpopulation of my survey data in Stata?
- Why doesn't summarize accept pweights? What does summarize calculate when you use aweights? (from Stata FAQs)
- Why doesn't the test of the overall survey regression model in Stata match the results from SAS and SUDAAN?

Two-way relation between interethnic social capital and drunk driving, risky drinking, binge drinking
Interethnic social capital is measured by frequency of interethnic drinking (at least monthly)
This is the model for drunk driving:
This is the model for binge drinking (expert definition, drinking 6 cups or more at a time)
This is the model for risky drinking (expert definition, AUDIT >7 for men)
This is the model for binge drinking (an ‘agreed’ version between ‘expert knowledge’ and ‘lay knowledge’)
This is the model for risky drinking (an ‘agreed’ version between ‘expert knowledge’ and ‘lay knowledge’)
Drinking a cup of tea, performing an identity
![]() | Take them home. Dry them up – until they become a bit dark, black. Serve with hot water, using a tea pot, or a coffee cup. Add sugar if you like. In rural area, you may want to call a friend over and share it with him, her. |
So, have you had a cup of tea today?
Interested in a tea/alcohol/coffee research? Consider using identity performance framework. We drink to express, symbolically, our gender, ethnic, class identities. However, somebody may always there, who have the power to interpret, label, stigmatise our performance. We need to negotiate by repeating the performance, talking about it, explaining it. We use ‘techniques of information control’, ‘techniques of neutralization’, and perhaps strategy of mitigation as well, if we feel like what we ‘ve just said is ‘politically incorrect’! (I am not racist, but his practice is very backward!)
Look at Goffman (1959) for a definition of ‘performance’
Look at Butler (1989) for a definition of gender performance
Look at Connell (1987) for a definition of negation (reduce similarities)
Look at Room (2005) for a piece on ethnic performance
Guide for Chapter Formation

1) what is the aim of this chapter?
2) what is going to happen (what will be presented here)?
3) Heading 1: say about it, but keep mentioning in passing other key ideas in the chapter
4) Heading 2: say about it, and referring back to what have been said so far
5) Provide a conclusion:
- a summary of what have been mentioned
- highlight the idea/concept (among many things you mentioned) that is important at most in your work

How to spend the last month of your PhD crazily?
It is not easy. You have to do the following:
1) Write only when all the ideas are clear to you
2) Disagree with your academic adviser’s style of commenting
3) Follow your working routine: wakeup at 5, leave home at 7, stop for lunch at 12, and come back to work at 2, leave for dinner at 8, and sleep at 11
4) Read more, since you keep finding new articles
5) Stop being nice with people because you ‘are busy’
6) Watch some movies, nice pictures, face booking,
7) Forget about visa expiration
8) Forget about financial stuff
9) For get all the ‘hygienic stuff’
10) Eat biscuits everyday – or ask somebody to buy it for you
HOW TO deal with ENDOGENEITY of binary variable
I-SHORT ANSWER
This is a common problem in social sciences,
y= x1……..xn, but
x1=x2…..xn
How to deal with it? In Stata, use ivprobit if the suspected endogenous variable is continuous, if it is binary/discrete, use treatreg.
II-LONG ANSWER
look for lnsigma and athrho
1) meaning of lnsigma
lnsigma = log of sigma
sigma could be understood as standard error of….what?
of ….correlation….between what?
2) meaning of athrho
athrho= transformation of rho, and rho is basically a correlation measure
In this context, rho is the correlation between the errors (residuals) of the probit equation (full equation) and the reduced equation for the suspected endogenous variable (now let us call this correlation between two residuals ‘A’)
full model: y=x1+……………….xn ---> error 1
reduced model: x1=x2….xn --->error 2
Does error1 correlate significantly with error2?
The task here is to test a Ho : there is no endogeneity problem in the set of predictors in relation with the dependent variable. In other words, we test that A is not significant.
if athrho >0.05, that means the possibility that A is not significant is larger than 5%
if athrho <0.05, that means the chance for A to be insignificant is very tiny.
IN SHORT, IF athrho is larger than 5%, we can say that: we cannot reject Ho, or, it is less likely that there is an endogeneity issue in here.
Then WHAT ---> RUN a normal model using probit or logit, depending on what you like, then use it for final results.
IF athrho <0.05, you should keep the output result of ivprobit, which include estimate for both models
NOTE THAT: ivprobit should be used for continuous (suspected) endogenous variable. Consider transform your variable if it is discrete. Nevertheless, the test idea is the same: Does residual in FULL MODEL significantly correlate with residual in REDUCED MODEL?
Consider using –treatreg FOR BINARY endogenous variable:
svy, subpop(sex): treatreg [Y] [ALL_X] , treat(BINARYVARGOESHERE = ALL_X)
est store m1
estout m1, cells(b(star fmt(3)) ) l starlevels(+ 0.1 * 0.05 ** 0.01 *** 0.001) stats(N F,star(r2 p))
