[{"publication":"The Journal of Information Systems Security (AIS Special Interest Group in Security)","abstract":[{"text":"Spam e-mails have become a serious technological and economic problem. Up to now, by deploying complementary anti-spam measures, we have been reasonably able to withstand spam e-mails and use the Internet for regular communication. However, if we are to avert the danger of losing the Internet e-mail service in its capacity as a valuable, free and worldwide medium of open communication, anti-spam activities should be performed more systematically than is currently the case regarding the mainly heuristic, anti-spam measures in place. A formal framework, within which the existing delivery routes that a spam e-mail may take, and anti-spam measures and their effectiveness can be investigated, will perhaps encourage a shift in methodology and pave the way for new, holistic anti-spam measures. This paper presents a model of the Internet e-mail infrastructure as a directed graph and a deterministic finite automaton and draws on automata theory to formally derive the spam delivery routes. The most important anti-spam measures are then described. Methods controlling only specific delivery routes are evaluated in terms of how effectively they cover the modeled e-mail infrastructure; methods operating independently of any particular routes receive a more general assessment.","lang":"eng"}],"file":[{"content_type":"application/pdf","relation":"main_file","creator":"hsiemes","date_created":"2018-12-18T13:25:12Z","date_updated":"2018-12-18T13:25:12Z","file_name":"Do anti-spam measures effectively cover the e-mail communication - Journal version.pdf","access_level":"open_access","file_id":"6324","file_size":100448}],"keyword":["e-mail","spam","e-mail infrastructure","anti-spam measures","spamming options"],"ddc":["000"],"language":[{"iso":"eng"}],"issue":"2","year":"2007","date_created":"2018-11-14T14:51:41Z","title":"Do anti-spam measures effectively cover the e-mail communication network?

Even worse, the impacts of these messages are far from being simply an annoyance, as they also involve economic damage. This manuscript examines the resource ?email addresses?, which is vital for any potential bulk mailer and spammer. Both a methodology and a honeypot conceptualization for implementing an empirical analysis of the usage of email addresses placed on the Internet are proposed here. Their objective is to assess, on a quantitative basis, the extent of the current harassment and its development over time. This ?framework? is intended to be extensible to measuring the effectiveness of address-obscuring techniques. The implementation of a pilot honeypot is described, which led to key findings, some of them being: (1) Web placements attract more than two-thirds (70\\%) of all honeypot spam emails, followed by newsgroup placements (28.6\\%) and newsletter subscriptions (1.4\\%), (2) the proportions of spam relating to the email addresses? top-level domain can be statistically assumed to be uniformly distributed, (3) More than 43\\% of addresses on the web have been abused, whereas about 27\\% was the case for addresses on newsgroups and only about 4\\% was the case for addresses used for a newsletter subscription, (4) Regarding the development of email addresses? attractiveness for spammers over time, the service ?web sites? features a negative linear relationship, whereas the service ?Usenet? hows a negative exponential relationship. (5) Only 1.54\\% of the spam emails showed an interrelation between the topic of the spam email and that of the location where the recipient?s address was placed, so that spammers are assumed to send their emails in a ?context insensitive? manner. The results of the empirical analysis motivate the need for the protection of email addresses through obscuration. We analyze this need by formulating requirements for address obscuring techniques and we reveal to which extent today?s most relevant approaches fulfill these requirements."}],"file":[{"relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_name":"The Impact that Placing Email Addresses on the Internet has on the Receipt of Spam - An Empirical Analysis - Journal version.pdf","file_id":"6326","file_size":3026200,"date_created":"2018-12-18T13:27:01Z","creator":"hsiemes","date_updated":"2018-12-18T13:27:01Z"}],"publication":"Computers & Security"},{"main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2007/BeEbHa07.pdf","open_access":"1"}],"title":"Channel Estimation by Exploiting Sublayer Information in OFDM Systems","date_created":"2019-07-12T05:26:57Z","author":[{"full_name":"Bevermeier, Maik","last_name":"Bevermeier","first_name":"Maik"},{"first_name":"Tobias","last_name":"Ebel","full_name":"Ebel, Tobias"},{"first_name":"Reinhold","id":"242","full_name":"Haeb-Umbach, Reinhold","last_name":"Haeb-Umbach"}],"date_updated":"2022-01-06T06:51:07Z","oa":"1","citation":{"bibtex":"@inproceedings{Bevermeier_Ebel_Haeb-Umbach_2007, title={Channel Estimation by Exploiting Sublayer Information in OFDM Systems}, booktitle={Multi-Carrier Spread Spectrum 2007}, author={Bevermeier, Maik and Ebel, Tobias and Haeb-Umbach, Reinhold}, year={2007} }","mla":"Bevermeier, Maik, et al. “Channel Estimation by Exploiting Sublayer Information in OFDM Systems.” <i>Multi-Carrier Spread Spectrum 2007</i>, 2007.","short":"M.

While this approach has extensively been employed in narrowband (antenna) array beamforming, it is typically not used for broadband (microphone) array beamforming due to the uncontrolled amount of speech distortion introduced by a narrowband SNR criterion. In this paper, we show how the distortion of the desired signal can be controlled by a single-channel post-filter, resulting in a performance comparable to the generalized minimum variance distortionless response beamformer, where arbitrary transfer functions relate the source and the microphones. Results are given both for directional and diffuse noise. A novel gradient ascent adaptation algorithm is presented, and its good convergence properties are experimentally revealed by comparison with alternatives from the literature. A key feature of the proposed beamformer is that it operates blindly, i.e., it neither requires knowledge about the array geometry nor an explicit estimation of the transfer functions from source to sensors or the direction-of-arrival.","lang":"eng"}],"publication":"IEEE Transactions on Audio, Speech, and Language Processing","doi":"10.1109/TASL.2007.898454","main_file_link":[{"open_access":"1","url":"https://groups.uni-paderborn.de/nt/pubs/2007/WaHa07.pdf"}],"volume":15,"author":[{"first_name":"Ernst","last_name":"Warsitz","full_name":"Warsitz, Ernst"},{"last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold","id":"242","first_name":"Reinhold"}],"oa":"1","date_updated":"2022-01-06T06:51:12Z","intvolume":"        15","page":"1529-1539","citation":{"ama":"Warsitz E, Haeb-Umbach R.

These models predict that the perceptual latency of a visual backward mask is shorter than that of a like reference stimulus that was not preceded by a masked stimulus. The prediction has been confirmed by studies using temporal-order judgments: For certain asynchronies between mask and reference stimulus, temporal-order reversals are quite frequent (e.g. Scharlau, & Neumann, 2003a). However, it may be argued that these reversals were due to a response bias in favour of the mask rather than true temporal-perceptual effects.

The starting point for the studies included in this special issue is the assumption that the same can be said for European countries. Thus, a comparison of characteristics of emerging adulthood between different European countries was performed. In this special issue, contributions of scholars from five different European countries are taken as representative of different regions: Spain, Italy, Finland, Germany, and the Czech Republic. The efforts of the research are twofold. The first is to look at how the traditional markers of adulthood have changed and how the concept of adulthood is seen in the different countries. The second is to highlight the influence that the entrance into the working world and romantic partnership have on emerging adults and to detect the impact of the timing of entering adulthood on identity achievement. The results are presented here as different pathways that emerging adults follow to reach the same goal of mature adulthood."}],"publication":"Journal of Adolescent Research","doi":"https://doi.org/10.1177/0743558407306345","main_file_link":[{"open_access":"1","url":"https://journals.sagepub.com/doi/pdf/10.1177/0743558407306345"}],"date_updated":"2022-08-29T03:29:23Z","oa":"1","volume":22,"author":[{"first_name":"Heike M.","full_name":"Buhl, Heike M.","id":"27152","last_name":"Buhl"},{"full_name":"Lanz, Margherita","last_name":"Lanz","first_name":"Margherita"}],"page":"439 - 443","intvolume":"        22","citation":{"mla":"Buhl, Heike M., and Margherita Lanz. “Emerging Adulthood in Europe.
