Second‐Generation “Return” to Greece: New Dynamics of Transnationalism and Integration

Based on in‐depth narrative interviews with 64 second‐generation Greek‐Germans and Greek‐Americans who have “returned” to Greece, this article explores intersections between return, transnationalism and integration. Having grown up with a strong Greek identity in the diaspora, second‐generation “returnees” move to Greece mainly for idealistic, lifestyle and life‐stage reasons. However, most find living in Greece long‐term a challenging experience: they remark on the corruption and chaos of Greek life, and are surprised at the high level of xenophobia in Greek society, not only towards foreign immigrants but also towards themselves as “hyphenated Greeks”. The “return” to Greece provokes new “reverse” transnational links back to their birth country, where they still need to keep in touch with relatives and friends, including caring obligations towards parents who remain abroad. Some contemplate another “return”, back to the US or Germany.

Policy Implications

• Policymakers responsible for integration should not assume that the second generation has no connections with its parents' country of origin.
• In the diasporic home country (in this case Greece), more effort should be made to facilitate the reintegration of the second generation returning ‘home’ and to break down discrimination towards hyphenated Greeks.
• Greek policymakers should pay heed to homecoming second‐generation Greeks in order to benefit from their bicultural insights into how Greek society can be improved, especially as regards efficient public services, transparent employment opportunities, better environment management, gender equality, and the elimination of racism and discrimination.

     

The Associations of Financial Stress and Parenting Support Factors with Alcohol Behaviors During Young Adulthood

This study examined concurrent and prospective associations of financial stress (financial strain, lack of financial access, public assistance) and parenting support factors (relationship quality, living at home, financial support) with young adults’ alcohol behaviors (alcohol use, heavy drinking, and problematic drinking) over a 5-year period. Analyses of National Longitudinal Study of Adolescent Health (Add Health) data (N = 7,159) showed that, over the study period, alcohol use and heavy drinking declined while problematic drinking increased. In addition, living at home and parental relationship quality were associated with fewer concurrent and prospective alcohol behaviors whereas financial strain and parents’ financial support were associated with more alcohol behaviors. The implications for minimizing alcohol misuse in young adults amid uncertain economic conditions are discussed.     

Using High-Frequency Data in Dynamic Portfolio Choice

This article evaluates the economic benefit of methods that have been suggested to optimally sample (in an MSE sense) high-frequency return data for the purpose of realized variance/covariance estimation in the presence of market microstructure noise (Bandi and Russell, 2005a, 2008). We compare certainty equivalents derived from volatility-timing trading strategies relying on optimally-sampled realized variances and covariances, on realized variances and covariances obtained by sampling every 5 minutes, and on realized variances and covariances obtained by sampling every 15 minutes. In our sample, we show that a risk-averse investor who is given the option of choosing variance/covariance forecasts derived from MSE-based optimal sampling methods versus forecasts obtained from 5- and 15-minute intervals (as generally proposed in the literature) would be willing to pay up to about 80 basis points per year to achieve the level of utility that is guaranteed by optimal sampling. We find that the gains yielded by optimal sampling are economically large, statistically significant, and robust to realistic transaction costs.     

Are there interregional differences in the response of cigarette smoking to state cigarette excise taxes in the USA? Exploratory analysis

Within the context of the period fixed-effects model, this study uses a 2002–2009 state-level panel data set of the USA to investigate the relative impact of state cigarette excise taxation across the nation in reducing cigarette smoking. In particular, by focusing upon the state cigarette excise taxation levels within each of the nine US Census Divisions, this study investigates whether there are inter-regional differences in the rate of responsiveness of cigarette consumption to increased state cigarette taxes. The initial empirical estimates reveal that although the per capita number of packs of cigarettes smoked annually is a decreasing function of the state cigarette excise tax in all nine Census Regions, the relative response of cigarette smoking to state cigarette tax increases varies considerably from one region to the next. Reinforcing this conclusion, in one specification of the model, the number of packs of cigarettes smoked in response to a higher state cigarette tax is statistically significant and negative in only eight of the nine Census Divisions. Furthermore, when cigarette smoking is measured in terms of the percentage of the population classified as smokers, interregional differentials in the response of smokers to higher state cigarette taxes are much greater. Thus, there is evidence that cigarette excise taxation exercises rather different impacts on the propensity to smoke across Census Regions.     

The randomized concentration-controlled trial:mathematical definitions,a dose-adjusting algorithm,and sample size efficiency

A randomized concentration-controlled trial (RCCT) (Peck 1990) is distinguished from a randomized dose-controlled trial (RDCT) by controlling the plasma concentration and allowing the dose to vary, as opposed to controlling the dose and allowing the concentration to vary. Monte Carlo studies have suggested that the RCCT is more efficient (in terms of sample size) than the more traditional dose-controlled trials. This paper presents a general mathematical defminition and investigates the properties of an RCCT. A Bayesian adjustment algorithm used in an RCCT is presented and discussed. Expressions for the sample-size efficiency of the RCCT relative to the RDCT is found for both Gaussian and Bernoulli efficacy variables. The RCCT is found to be at least as efficient in terms of sample size. The RCCT can be considerably more efficient than the RDCT.     

Dependence of F Ratios Sharing a Common Denominator Mean Square

Much has changed since the widespread introduction of statistics courses into the university curriculum, but the way introductory statistics courses are taught has not kept up with these changes. This article discusses the changes, and the way the introductory syllabus should change to reflect them. In particular, seven ideas are discussed that every student who takes elementary statistics should learn and understand in order to be an educated citizen. Misunderstanding these topics leads to cynicism among the public at best, and misuse of study results by policy-makers, physicians, and others at worst.     

On A method for selecting a distributional model

A method for selecting a distributional model for a random variable, given a random sample of observations of it, is studied for various cases. The problems considered include those of choosing between the Weibull and lognormal distributions, between the lognormal and gamma distributions, and between the gamma and Weibull distributions, as well as choosing one of the three. Simulation studies were performed to estimate probabilities of correct selection for the method when it is applied to these problems
