Hur gick det för 1960- och 1970-talets svenska narkotikamissbrukare?
Authors: Alm Susanne 
Published: April 2015

What happened to the Swedish problem drug users of the 1960's and 1970's? AimS & DESIGN – In this study we follow a Stockholm birth cohort born in 1953 (n= 14 294) from youth to middle age. The cohort members were in their teenage years when drug abuse was established as a considerable threat to Swedish society and some of the cohort members themselves became drug abusers (n=431). Results – As expected, life became dramatically worse for those with documented drug abuse when young, than for the rest of the cohort members. While 72 percent of those without documented drug abuse were socially included at the age of 56, the corresponding share among those with documented drug abuse was 18 per cent. And while 5 percent in the former group were diseased at 56, this was true for 38 percent in the latter group. Supplementary analyses showed that social inclusion was also less stable among those with documented drug abuse than among the rest of the cohort, and that the flow from exclusion to inclusion was virtually nonexistent, which was not the case for those without experience of drug abuse. Conclusions – Gender specific analyses showed that the situation, at least in absolute terms, tended to be even worse for male drug abusers than for women. Gender differences in alcohol abuse, criminality, and with respect to parenthood are suggested as possible explanations to be further studied in future research.

Published: April 2015

Aims This article describes and analyses prisoners' experiences of drug treatment in prison in four Nordic countries: Denmark, Finland, Norway and Sweden. The article examines how prisoners experience drug treatment, control and sanctions as related to three main topics, namely motivation; the content of the measure and relations to staff; and control and sanctions. Methods & DATA – The article is based on data from twelve prisons, three in each of the four countries; 91 interviews with prisoners; and around six months of observation. The two main kinds of drug treatment measures are drug treatment units and day programmes. Results – Prisoners described several motives to participate in drug treatment measures: to leave drugs and crime; to renew relations with family and friends; to solve health problems; and to improve their prison conditions. Prisoners found that drug treatment measures offered possibilities to acquire new ways of being. Staff behaviour seemed to be more important to prisoners than the methods used, and some prisoners seemed more positive to staff involved with the drug treatment than to other staff. A surprising finding was the prisoners' limited critique of controls and sanctions. We see this as embedded in the situation of being a prisoner, and also in relation to contexts outside prison. Conclusion In discussing their experiences in the treatment units, prisoners are not so concerned about the rehabilitative features or the controls and sanctions. They evaluate their present situation in light of a future, which is their real concern. This is in line with a main task for staff, which is to prepare prisoners for release.
Know Thy Neighbor: Crypto Library Detection in Cloud

Published: April 2015

Abstract
Software updates and security patches have become a standard method to fix known and recently discovered security vulnerabilities in deployed software. In server applications, outdated cryptographic libraries allow adversaries to exploit weaknesses and launch attacks with significant security results. The proposed technique exploits leakages at the hardware level to first, determine if a specific cryptographic library is running inside (or not) a co-located virtual machine (VM) and second to discover the IP of the co-located target. To this end, we use a Flush+Reload cache side-channel technique to measure the time it takes to call (load) a cryptographic library function. Shorter loading times are indicative of the library already residing in memory and shared by the VM manager through deduplication. We demonstrate the viability of the proposed technique by detecting and distinguishing various cryptographic libraries, including MatrixSSL, PolarSSL, GnuTLS, OpenSSL and CyaSSL along with the IP of the VM running these libraries. In addition, we show how to differentiate between various versions of libraries to better select an attack target as well as the applicable exploit. Our experiments show a complete attack setup scenario with single-trial success rates of up to 90% under light load and up to 50% under heavy load for libraries running in KVM.
Portrait of a Privacy Invasion
Authors: Shoshitaishvili Yan , Kruegel Christopher , Vigna Giovanni 
Published: April 2015

Abstract
The popularity of online social networks has changed the way in which we share personal thoughts, political views, and pictures. Pictures have a particularly important role in the privacy of users, as they can convey substantial information (e.g., a person was attending an event, or has met with another person). Moreover, because of the nature of social networks, it has become increasingly difficult to control who has access to which content. Therefore, when a substantial amount of pictures are accessible to one party, there is a very serious potential for violations of the privacy of users. In this paper, we demonstrate a novel technique that, given a large corpus of pictures shared on a social network, automatically determines who is dating whom, with reasonable precision. More specifically, our approach combines facial recognition, spatial analysis, and machine learning techniques to determine pairs that are dating. To the best of our knowledge, this is the first privacy attack of this kind performed on social networks. We implemented our approach in a tool, called Creepic, and evaluated it on two real-world datasets. The results show that it is possible to automatically extract non-obvious, and nondisclosed, relationships between people represented in a group of pictures, even when the people involved are not directly part of a connected social clique.
Analyzing the Great Firewall of China Over Space and Time

Published: April 2015

Abstract
A nation-scale firewall, colloquially referred to as the “Great Firewall of China,” implements many different types of censorship and content filtering to control China’s Internet traffic. Past work has shown that the firewall occasionally fails. In other words, sometimes clients in China are able to reach blacklisted servers outside of China. This phenomenon has not yet been characterized because it is infeasible to find a large and geographically diverse set of clients in China from which to test connectivity. In this paper, we overcome this challenge by using a hybrid idle scan technique that is able to measure connectivity between a remote client and an arbitrary server, neither of which are under the control of the researcher performing measurements. In addition to hybrid idle scans, we present and employ a novel side channel in the Linux kernel’s SYN backlog. We show that both techniques are practical by measuring the reachability of the Tor network which is known to be blocked in China. Our measurements reveal that failures in the firewall occur throughout the entire country without any conspicuous geographical patterns.We give some evidence that routing plays a role, but other factors (such as how the GFW maintains its list of IP/port pairs to block) may also be important.
The Need of Belonging and Sense of Belonging versus Effectiveness of Coping
Authors: Wilczyńska Agnieszka , Januszek Maciej , Bargiel-Matusiewicz Kamilla 
Published: April 2015

Abstract
The aim of this research was to describe the dependence between the need for and sense of belonging and symptoms of depression vs. one’s capacity to cope effectively. Using path analysis of our data (N = 178), we found direct patterns, in which both depression symptoms and life satisfaction depend to a considerable degree on the sense of belonging. The belonging need influences, in a direct way, the coping focused on the search for social support. Undertaking active techniques of coping, including confrontation with a stressful situation and its negative controlling impact, depends on having a high level of the sense of belonging. In contrast, individuals who cope by means of taking psychoactive drugs show the symptoms of depression.
Self-compassion and social functioning of people – research review
Authors: Dzwonkowska Irena , Żak-Łykus Alicja 
Published: April 2015

Abstract
Self-compassion is considered to be a healthy and adaptive attitude towards oneself, occurring both as a feature, as well as a state. Self-compassionate attitude towards oneself is composed of: a) kindness and understanding given to oneself b) mindfulness of one’s own experiences and c) a sense of community of experiences with humanity. Compassion towards oneself is structurally and functionally distinct from the self-commiseration and self-pity that lead to worse adaptation. Research shows that self-compassion is associated with better regulation of negative emotions. Neff (2003 a) in her theoretical assumption states that due to more effective emotion regulation , people with a higher level of selfcompassion can generally cope better with reality. Therefore a question arises as to what the relationship is between a compassionate attitude towards oneself and social functioning of people. This article is a review of research that has been conducted so far regarding relations between self-compassion and the various dimensions of social functioning.
Preferential access to emotion under attentional blink: evidence for threshold phenomenon
Authors: Szczepanowski Remigiusz , Traczyk Jakub , Fan Zhao , Harvey Lewis O. 
Published: April 2015

Abstract
The present study provides evidence that the activation strength produced by emotional stimuli must pass a threshold level in order to be consciously perceived, contrary to the assumption of continuous quality of representation. An analysis of receiver operating characteristics (ROC) for attentional blink performance was used to distinguish between two (continuous vs. threshold) models of emotion perception by inspecting two different ROC’s shapes. Across all conditions, the results showed that performance in the attentional blink task was better described by the two-limbs ROC predicted by the Krantz threshold model than by the curvilinear ROC implied by the signal-detection theory.
Domain Adaptation for Machine Translation with Instance Selection
Authors: Biçici Ergun 
Published: April 2015

Abstract
Domain adaptation for machine translation (MT) can be achieved by selecting training instances close to the test set from a larger set of instances. We consider 7 different domain adaptation strategies and answer 7 research questions, which give us a recipe for domain adaptation in MT. We perform English to German statistical MT (SMT) experiments in a setting where test and training sentences can come from different corpora and one of our goals is to learn the parameters of the sampling process. Domain adaptation with training instance selection can obtain 22% increase in target 2-gram recall and can gain up to 3:55 BLEU points compared with random selection. Domain adaptation with feature decay algorithm (FDA) not only achieves the highest target 2-gram recall and BLEU performance but also perfectly learns the test sample distribution parameter with correlation 0:99. Moses SMT systems built with FDA selected 10K training sentences is able to obtain F1 results as good as the baselines that use up to 2M sentences. Moses SMT systems built with FDA selected 50K training sentences is able to obtain F1 point better results than the baselines.
Scalable Reordering Models for SMT based on Multiclass SVM
Authors: Alrajeh Abdullah , Niranjan Mahesan 
Published: April 2015

Abstract
In state-of-the-art phrase-based statistical machine translation systems, modelling phrase reorderings is an important need to enhance naturalness of the translated outputs, particularly when the grammatical structures of the language pairs differ significantly. Posing phrase movements as a classification problem, we exploit recent developments in solving large-scale multiclass support vector machines. Using dual coordinate descent methods for learning, we provide a mechanism to shrink the amount of training data required for each iteration. Hence, we produce significant computational saving while preserving the accuracy of the models. Our approach is a couple of times faster than maximum entropy approach and more memory-efficient (50% reduction). Experiments were carried out on an Arabic-English corpus with more than a quarter of a billion words. We achieve BLEU score improvements on top of a strong baseline system with sparse reordering features.
Types of Geoecosystems of the Lobelia Lakes of the Tricity Area
Authors: Markowski Maciej , Kwidzińska Monika 
Published: April 2015

Abstract
In the years 2009-2010 limnological research was carried out on 13 lobelia lakes of the Tricity metropolitan area. These lakes, of unique value not only on the scale of the country, are undergoing degradation due to increasing anthropogenic pressure. Grade of degradation of these lakes, depends on geoecosystem type, which they are representing. Geoecosystem type of the lake, defines the rate of natural eutrophication of reservoir. In this article types of geoecosystems of analysed lobelia lakes where defined in accordance with the guidelines of Bajkiewicz-Grabowska (1981, 1983, 1985, 1987, 2002). The obtained results indicate that only one of the analysed lakes (Zawiat Lake) is likely to retain a low trophic level. Four lakes (Głębokie, Kamień, Borowo, Techlinko) represent geoecosystems with a moderate rate of natural eutrophication. The remaining of the analysed lobelia lakes are threatened with fast water eutrophication, which is demonstrated by a high catchment vulnerability to activate areal load, and a low resistance of the lakes (resulting from their natural properties) to external supply. The obtained results correspond to field measurements and make it possible to indicate actions aimed at protecting the group of the analysed lobelia lakes.
The Isle of The Dead Benchmark, the Sydney, Fort Denison Tide Gauge and the Ipcc Ar5 Chapter 13 Sea Levels Revisited
Authors: Parker Albert 
Published: April 2015

Abstract
The paper revisits the Isle of the Dead benchmark and the Sydney, Fort Denison tide gauge to confirm that long term, high quality tide gauges are acceleration free, consistently to the analysis of key sites suggesting the sea levels are not sharply raising following the carbon dioxide emissions. The paper also discusses the flaws of the IPCC AR5 Chapter13 Sea levels. The time history of the relative rate of rise computed by linear fitting of the data locally collected by tide gauges is the best parameter to assess the effect of global warming providing length and quality requirements are satisfied. There is no reason to search for less reliable alternative methods because the climate models predicted different trends. The Global Positioning System (GPS) inferred vertical tide gauge velocity suffers of significant inaccuracies. Larger inaccuracies are provided by the satellite altimetry Global Mean Sea Level (GMSL) that is a computation and not a measurement.
Well-being in the Czech Republic in an Aggregate Perspective
Authors: Fialová Kamila , Štika Pavel 
Published: April 2015

Abstract
The article assesses well-being in the Czech Republic compared to other Visegrad countries (Slovakia, Hungary, Poland) and neighbouring Germany and Austria. By employing various approaches designed by several international organisations it takes an aggregate perspective to assess both the current well-being and its sustainability into the future. All employed indicators that relate to current well-being evaluate the well-being in the Czech Republic as moderate among the OECD countries. The results indicate that the position in well-being rankings improves with the growing number of dimensions or subjective factors included in the well-being measure, mainly due to the reduction in relative importance of income dimension and higher emphasis on the multidimensionality and complexity of well-being. In the case of sustainability, large differences can be identified in evaluation stemming from Happy Planet Index and Sustainable Society Index perspective. Although both of them agree on unfavourable situation as regards environmental sustainability in the Czech Republic, different accent on economic area alters the final result substantially. The analysis shows that for any well-being assessment, the choice of indicators is crucial and a large portion of caution is necessary when interpreting these.
On the shortfall risk control: A refinement of the quantile hedging method
Authors: Barski Michał 
Published: April 2015

Abstract
The issue of constructing a risk minimizing hedge under an additional almost-surely type constraint on the shortfall profile is examined.
Several classical risk minimizing problems are adapted to the new setting and solved. In particular, the bankruptcy threat of optimal strategies appearing in the classical risk minimizing setting is ruled out. The existence and concrete forms of optimal strategies in a general semimartingale market model with the use of conditional statistical tests are proven. The quantile hedging method applied in
[Finance Stoch. 3 (1999), 251–273; Finance Stoch. 4 (2000), 117–146]
as well as the classical Neyman–Pearson lemma are generalized. Optimal hedging strategies with shortfall constraints in the Black–Scholes and exponential Poisson model are explicitly determined.

Published: April 2015

BACKGROUND AND OBJECTIVES:
Perinatal exposure is an important mode of hepatitis B virus (HBV) transmission, resulting in chronic disease in ∼90% of infected infants. Immunoprophylaxis recommended for infants born to hepatitis B surface antigen–positive mothers reduces up to 95% of perinatal HBV infections. We sought to identify factors associated with perinatal HBV transmission.

METHODS:
We analyzed prospectively collected data from 5 of 64 US-funded Perinatal Hepatitis B Prevention Programs during 2007–2013. We examined effects of maternal demographic and laboratory results, infant gestational age and birth weight, and immunoprophylactic management on perinatal HBV infection.

RESULTS:
Data from 17 951 mother-infant pairs were analyzed. Among 9252 (51.5%) infants for whom hepatitis B surface antigen testing results were available, 100 (1.1%) acquired perinatal HBV infection. Both hepatitis B (HepB) vaccine and hepatitis B immune globulin were administered within 12 hours of birth for 10 760 (94.9%) of 11 335 infants with information. Perinatal HBV infection was associated with younger maternal age (P = .01), Asian/Pacific Islander race (P &lt; .01), maternal hepatitis B e-antigen positivity (P &lt; .01), maternal antibody to hepatitis B e-antigen negativity (P &lt; .01), maternal viral load ≥2000 IU/mL (P = .04), and infant receipt of &lt;3 HepB vaccine doses (P = .01). Four infants born to 429 mothers with viral load testing were infected; all 4 were born to mothers with viral loads in the ninth or tenth decile.

CONCLUSIONS:
Perinatal HBV infection occurred among 1% of infants, most of whom received recommended immunoprophylaxis. Infants at greatest risk of infection were those born to women who were younger, hepatitis B e-antigen positive, or who had a high viral load or those infants who received &lt;3 HepB vaccine doses.
Guided-mode resonance and field enhancement in semiconductor nanorod arrays
Authors: Yu W. X. , Yi Y. 
Published: April 2015

ABSTRACTGuided mode resonance was numerically demonstrated in the tapered silicon nitride nanorod arrays on glass substrate. Finite difference time domain technique was employed to investigate the detailed light-matter interaction dynamics and the generation of resonance at femtoseconds. Enhanced electromagnetic (EM) field intensity with enhancement factor of 200∼250 could be achieved. This highly concentrated electromagnetic field could be extended to the nanorod array tips and substrate for higher order resonance modes, which allows future application of this transverse propagating field in optical signal amplification, like fluorescence or Raman enhancement.
Angiotensin(1-7) and ACE2, “The Hot Spots” of Renin-Angiotensin System, Detected in the Human Aqueous Humor
Authors: Holappa Mervi , Valjakka Jarkko , Vaajanen Anu 
Published: April 2015

Background:
The main purpose of the study was to establish whether essential components of the renin-angiotensin system (RAS) exist in the human aqueous humor.

Methods:
Forty-five patients ≥ 60 (74±7) years of age undergoing cataract surgery at Tampere University Hospital were randomly selected for the prospective study. The exclusion criterion was the use of oral antihypertensive medicine acting via renin-angiotensin system. Aqueous humor samples were taken at the beginning of normal cataract extraction. The samples were frozen and stored at -80 °C. The concentrations of intraocular endogenous RAS components Ang(1-7), ACE2, and ACE1 were measured using ELISA.

Results:
Concentration medians of Ang(1-7), ACE2, and ACE1 in the aqueous humor were: Ang(1-7) 4.08 ng/ml, ACE2 2.32 ng/ml and ACE1 0.35 ng/ml. The concentrations were significantly higher in glaucomatous than in non-glaucomatous eyes, ACE1 (p=0.014) and Ang(1-7) (p=0.026) vs non-glaucomatous eyes.

Conclusions:
Ang(1-7), ACE2 and ACE1 are found in the human aqueous humor. The observations are consistent with the conception that local tissue-RAS exists in the human eye and it might have a role in the control of intraocular pressure.
