This has been contingent on a change in its interpretation from a typological category to a semantic-pragmatic category, which allows an application to languages lacking specialised morphemes for the expression of evidentiality. We consider evidentiality to be a structural dimension of grammar, the values of which are expressed by types of constructions that code the source of information which a speaker imparts. If we look at the situation in Romance languages and in German, drawing a boundary between epistemic modality and evidentiality presents problems that are difficult to solve. Adding markers of the source of the speaker's knowledge often limits the degree of responsibility of the speaker for the content of the utterance. Evidential adverbs are a frequently used means of marking the source of the speaker's knowledge. The evidential meaning is generalised to marking any source of knowledge, what can be regarded as a result of a process of pragmaticalisation. The use of certain means which also carry out evidential markings can even contribute to the blurring of the different kinds of evidentiality. German also has modal verbs which in conjunction with the perfect tense of the verb have a predominantly evidential use (sollen and wollen). But even here the evidential marking is not without influence on the modality of the utterance. The Romance languages, however, do not have such specialised verbs for expressing evidentiality in certain contexts. To do this, they mark evidentiality - often context bound - by verb forms such as the conditional and the imperfect tense.

Design Structured review and meta-analysis. Methods Randomised controlled trials (RCTs), retrospective controlled cohort studies (rCCSs) and prospective controlled cohort studies (pCCSs) evaluating patients after acute coronary syndrome (ACS), coronary artery bypass grafting (CABG) or mixed populations with coronary artery disease (CAD) were included, provided the index event was in 1995 or later. Results Out of n=18,534 abstracts, 25 studies were identified for final evaluation (RCT: n=1; pCCS: n=7; rCCS: n=17), including n=219,702 patients (after ACS: n=46,338; after CABG: n=14,583; mixed populations: n=158,781; mean follow-up: 40 months). Heterogeneity in design, biometrical assessment of results and potential confounders was evident. CCSs evaluating ACS patients showed a significantly reduced mortality for CR participants (pCCS: hazard ratio (HR) 0.37, 95\% confidence interval (CI) 0.20-0.69; rCCS: HR 0.64, 95\% CI 0.49-0.84; odds ratio 0.20, 95\% CI 0.08-0.48), but the single RCT fulfilling Cardiac Rehabilitation Outcome Study (CROS) inclusion criteria showed neutral results. CR participation was also associated with reduced mortality after CABG (rCCS: HR 0.62, 95\% CI 0.54-0.70) and in mixed CAD populations.

A sediment core covering the last 55years from a small closed-basin lake in central Mongolia was analyzed for its multi-proxy record at annual resolution. Pollen analysis shows that highest abundances of planted Poaceae and highest vegetation diversity occurred during 1977-1992, reflecting agricultural development in the lake area. A decrease in diversity and an increase in Artemisia abundance after 1992 indicate enhanced vegetation degradation in recent times, most probably because of overgrazing and farmland abandonment. Human impact is the main factor for the vegetation degradation within the past decades as revealed by a series of redundancy analyses, while climate change and soil erosion play subordinate roles. High Pediastrum (a green algae) influx, high atomic total organic carbon/total nitrogen (TOC/TN) ratios, abundant coarse detrital grains, and the decrease of C-13(org) and N-15 since about 1977 but particularly after 1992 indicate that abundant terrestrial organic matter and nutrients were transported into the lake and caused lake eutrophication, presumably because of intensified land use. Thus, we infer that the transition to a market economy in Mongolia since the early 1990s not only caused dramatic vegetation degradation but also affected the lake ecosystem through anthropogenic changes in the catchment area.}, language = {en} } @misc{ChmielewskiDumontTrautwein2013, author = {Chmielewski, Anna K. and Dumont, Hanna and Trautwein, Ulrich}, title = {Tracking effects depend on tracking type}, series = {American educational research journal}, volume = {50}, journal = {American educational research journal}, number = {5}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-404052}, pages = {33}, year = {2013}, abstract = {The aim of the present study was to examine how different types of tracking— between-school streaming, within-school streaming, and course-by-course tracking—shape students' mathematics self-concept.

CKD carries prognostic relevance. We aimed to describe patient characteristics, risk factor management and control status of patients in cardiac rehabilitation (CR), differentiated by presence or absence of CKD. Design and methods: Data from 92,071 inpatients with adequate information to calculate glomerular filtration rate (GFR) based on the Cockcroft-Gault formula were analyzed at the beginning and the end of a 3-week CR stay. CKD was defined as estimated GFR <60 ml/min/1.73 m(2). Results: Compared with non-CKD patients, CKD patients were significantly older (72.0 versus 58.0 years) and more often had diabetes mellitus, arterial hypertension, and atherothrombotic manifestations (previous stroke, peripheral arterial disease), but fewer were current or previous smokers had a CHD family history. Exercise capacity was much lower in CKD (59 vs. 92Watts). Fewer patients with CKD were treated with percutaneous coronary intervention (PCI), but more had coronary artery bypass graft (CABG) surgery. Patients with CKD compared with non-CKD less frequently received statins, acetylsalicylic acid (ASA), clopidogrel, beta blockers, and angiotensin converting enzyme (ACE) inhibitors, and more frequently received angiotensin receptor blockers, insulin and oral anticoagulants. In CKD, mean low density lipoprotein cholesterol (LDL-C), total cholesterol, and high density lipoprotein cholesterol (HDL-C) were slightly higher at baseline, while triglycerides were substantially lower. This lipid pattern did not change at the discharge visit, but overall control rates for all described parameters (with the exception of HDL-C) were improved substantially. At discharge, systolic blood pressure (BP) was higher in CKD (124 versus 121 mmHg) and diastolic BP was lower (72 versus 74 mmHg). At discharge, 68.7\% of CKD versus 71.9\% of non-CKD patients had LDL-C <100 mg/dl. Physical fitness on exercise testing improved substantially in both groups. When the Modification of Diet in Renal Disease (MDRD) formula was used for CKD classification, there was no clinically relevant change in these results. Conclusion: Within a short period of 3-4 weeks, CR led to substantial improvements in key risk factors such as lipid profile, blood pressure, and physical fitness for all patients, even if CKD was present.}, language = {en} } @misc{Ganghof2012, author = {Ganghof, Steffen}, title = {Does public reason require super-majoritarian democracy?}, series = {Politics, philosophy \& economics}, volume = {12}, journal = {Politics, philosophy \& economics}, number = {2}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-477860}, pages = {18}, year = {2012}, abstract = {The project of public-reason liberalism faces a basic problem: publicly justified principles are typically too abstract and vague to be directly applied to practical political disputes, whereas applicable specifications of these principles are not uniquely publicly justified.

Also, three Pediastrum assemblage zones show changes of aquatic conditions: higher abundances of Pediastrum boryanum var. brevicorne (1706-1802); medium abundances of P. kawraiskyi and P. integrum (1802-1840 and 1920-1980), indicating cooler conditions while less eutrophic conditions are indicated by P. boryanum, and a mainly balanced composition with only small changes of cold- and warm-adapted Pediastrum species (1965-2011). In general, compositional Pediastrum species turnover is slightly higher than that indicated by pollen data (0.54 vs 0.34 SD), but both are only minor for this treeline location. In conclusion, the relevance of differentiation of Pediastrum species is promising and can give further insights into the relationship between lakes and their surrounding vegetation transferred onto climatic conditions.}, language = {en} } @misc{CaoHerzschuhNietal.2014, author = {Cao, Xianyong and Herzschuh, Ulrike and Ni, Jian and Zhao, Yan and B{\"o}hmer, Thomas}, title = {Spatial and temporal distributions of major tree taxa in eastern continental Asia during the last 22,000 years}, series = {The Holocene}, volume = {25}, journal = {The Holocene}, number = {1}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-404176}, pages = {13}, year = {2014}, abstract = {This study investigates the spatial and temporal distributions of 14 key arboreal taxa and their driving forces during the last 22,000 calendar years before ad 1950 (kyr BP) using a taxonomically harmonized and temporally standardized fossil pollen dataset with a 500-year resolution from the eastern part of continental Asia. Logistic regression was used to estimate pollen abundance thresholds for vegetation occurrence (presence or dominance), based on modern pollen data and present ranges of 14 taxa in China. Our investigation reveals marked changes in spatial and temporal distributions of the major arboreal taxa. The thermophilous (Castanea, Castanopsis, Cyclobalanopsis, Fagus, Pterocarya) and eurythermal (Juglans, Quercus, Tilia, Ulmus) broadleaved tree taxa were restricted to the current tropical or subtropical areas of China during the Last Glacial Maximum (LGM) and spread northward since c. 14.5 kyr BP. Betula and conifer taxa (Abies, Picea, Pinus), in contrast, retained a wider distribution during the LGM and showed no distinct expansion direction during the Late Glacial. Since the late mid-Holocene, the abundance but not the spatial extent of most trees decreased. The changes in spatial and temporal distributions for the 14 taxa are a reflection of climate changes, in particular monsoonal moisture, and, in the late Holocene, human impact. The post-LGM expansion patterns in eastern continental China seem to be different from those reported for Europe and North America, for example, the westward spread for eurythermal broadleaved taxa.}, language = {en} } @misc{BohlkenJacobSchaumetal.2017, author = {Bohlken, Jens and Jacob, Louis and Schaum, Peter and Rapp, Michael Armin and Kostev, Karel}, title = {Hip fracture risk in patients with dementia in German primary care practices}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {395}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-404526}, pages = {12}, year = {2017}, abstract = {The aim was to analyze the risk of hip fracture in German primary care patients with dementia.

Methods and results: 10-15 year-old athletes (n = 343) were screened using electro- and echocardiography. The electrocardiogram (ECG) was normal in 220 (64\%), mildly abnormal in 108 (31\%), and distinctly abnormal in 15 (4\%) athletes. Echocardiographic upper reference limits (URL, 97.5 percentile) for the left ventricular (LV) wall thickness in 10-11-year-old boys and girls were 9-10 mm and 8-9 mm, respectively; in 12-13-year-old boys and girls 9-10 mm; and in 14-15-year-old boys and girls 10-11 mm and 9-10 mm, respectively. Three athletes were excluded from competitive sports: one for symptomatic Wolff-Parkinson-White syndrome with a normal echocardiogram; one for negative T-waves in V-1-V-4 and a dilated right ventricle by echocardiography suggestive of (arrhythmogenic) right ventricular disease; and one for normal ECG and biscupid aortic valve including an aneurysm of the ascending aorta detected by echocardiography. Related to echocardiographic findings, the sensitivity and specificity of the ECG to identify cardiovascular abnormalities was 38\% and 64\%, respectively. The ECG's positive-predictive and negative-predictive values were 13\% and 88\%, respectively. The numbers needed to screen and calculated costs were 172 for ECG ( 7049), 172 for echocardiography ( 11,530), and 114 combining ECG and echocardiography ( 9323). Conclusions: Compared to adults, paediatric athletes presented with fewer distinctly abnormal ECGs, and there was no gender difference in paediatric athletes' ECG-pattern distribution.

Patients rated subjective sleep quality on a scale from 1 (poor) to 10 (best) and completed the Epworth Sleepiness Scale (ESS). Results Clinically significant sleep apnoea (AHI 15/h) was documented in 33\% of patients. Mean AHI was 1416/h (range 0-106/h). Sleep apnoea was defined as being of moderate severity in 18\% of patients (AHI 15-29/h) and severe in 15\% (AHI 30/h). There were small, but statistically significant, differences in ESS score and subjective sleep quality between patients with and without sleep apnoea. Logistic regression model analysis identified the following as risk factors for sleep apnoea in CR patients: age (per 10 years) (odds ratio (OR) 1.51; p<0.001), body mass index (per 5 units) (OR 1.31; p=0.001), male gender (OR 2.19; p<0.001), type 2 diabetes mellitus (OR 1.45; p=0.040), haemoglobin level (OR 0.91; p=0.012) and witnessed apnoeas (OR 1.99; p<0.001).

Crucially for evaluating the movement optionality account, children with SLI produce very few instances of embedded clauses where the relative clause head noun is pronounced in situ; in fact, such responses are more common among the typically developing child controls. These results underscore the difficulty German-speaking children with SLI have with structures involving movement, but provide no specific support for the movement optionality account.}, language = {en} } @misc{ReibisSalzwedelBuhlertetal.2016, author = {Reibis, Rona Katharina and Salzwedel, Annett and Buhlert, Hermann and Wegscheider, Karl and Eichler, Sarah and V{\"o}ller, Heinz}, title = {Impact of training methods and patient characteristics on exercise capacity in patients in cardiovascular rehabilitation}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {442}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-405302}, pages = {8}, year = {2016}, abstract = {Aim: We aimed to identify patient characteristics and comorbidities that correlate with the initial exercise capacity of cardiac rehabilitation (CR) patients and to study the significance of patient characteristics, comorbidities and training methods for training achievements and final fitness of CR patients. Methods: We studied 557 consecutive patients (51.7 {\AE} 6.9 years; 87.9\% men) admitted to a three-week in-patient CR. Cardiopulmonary exercise testing (CPX) was performed at discharge. Exercise capacity (watts) at entry, gain in training volume and final physical fitness (assessed by peak O 2 utilization (VO 2peak ) were analysed using analysis of covariance (ANCOVA) models. Results: Mean training intensity was 90.7 {\AE} 9.7\% of maximum heart rate (81\% continuous/19\% interval training, 64\% additional strength training). A total of 12.2 {\AE} 2.6 bicycle exercise training sessions were performed. Increase of training volume by an average of more than 100\% was achieved (difference end/beginning of CR: 784 {\AE} 623 watts {\^A} min). In the multivariate model the gain in training volume was significantly associated with smoking, age and exercise capacity at entry of CR. The physical fitness level achieved at discharge from CR as assessed by VO 2peak was mainly dependent on age, but also on various factors related to training, namely exercise capacity at entry, increase of training volume and training method. Conclusion: CR patients were trained in line with current guidelines with moderate-to-high intensity and reached a considerable increase of their training volume. The physical fitness level achieved at discharge from CR depended on various factors associated with training, which supports the recommendation that CR should be offered to all cardiac patients.}, language = {en} } @misc{LauterbachWittPlessenetal.2017, author = {Lauterbach, Stefan and Witt, Roman and Plessen, Birgit and Dulski, Peter and Prasad, Sushma and Mingram, Jens and Gleixner, Gerd and Hettler-Riedel, Sabine and Stebich, Martina and Schnetger, Bernhard and Schwalb, Antje and Schwarz, Anja}, title = {Climatic imprint of the mid-latitude Westerlies in the Central Tian Shan of Kyrgyzstan and teleconnections to North Atlantic climate variability during the last 6000 years}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-404085}, pages = {15}, year = {2017}, abstract = {In general, a moderate drying trend is observed in mid-latitude arid Central Asia since the Mid-Holocene, attributed to the progressively weakening influence of the mid-latitude Westerlies on regional climate. However, as the spatio-temporal pattern of this development and the underlying climatic mechanisms are yet not fully understood, new high-resolution paleoclimate records from this region are needed. Within this study, a sediment core from Lake Son Kol (Central Kyrgyzstan) was investigated using sedimentological, (bio) geochemical, isotopic, and palynological analyses, aiming at reconstructing regional climate development during the last 6000 years. Biogeochemical data, mainly reflecting summer moisture conditions, indicate predominantly wet conditions until 4950 cal. yr BP, succeeded by a pronounced dry interval between 4950 and 3900 cal. yr BP. In the following, a return to wet conditions and a subsequent moderate drying trend until present times are observed. This is consistent with other regional paleoclimate records and likely reflects the gradual Late Holocene diminishment of the amount of summer moisture provided by the mid-latitude Westerlies. However, climate impact of the Westerlies was apparently not only restricted to the summer season but also significant during winter as indicated by recurrent episodes of enhanced allochthonous input through snowmelt, occurring before 6000 cal. yr BP and at 5100-4350, 3450-2850, and 1900-1500 cal. yr BP. The distinct similar to 1500year periodicity of these episodes of increased winter precipitation in Central Kyrgyzstan resembles similar cyclicities observed in paleoclimate records around the North Atlantic, likely indicating a hemispheric-scale climatic teleconnection and an impact of North Atlantic Oscillation (NAO) variability in Central Asia.}, language = {en} } @misc{ClahsenBalkhairSchutteretal.2013, author = {Clahsen, Harald and Balkhair, Loay and Schutter, John-Sebastian and Cunnings, Ian}, title = {The time course of morphological processing in a second language}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {379}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-403684}, pages = {25}, year = {2013}, abstract = {We report findings from psycholinguistic experiments investigating the detailed timing of processing morphologically complex words by proficient adult second (L2) language learners of English in comparison to adult native (L1) speakers of English.

The lake is located in the coastal infra-Mediterranean vegetation belt at 2 m a.s.l. Pollen, charcoal and sedimentological analyses are used to explore linkages among vegetation, fire and climate at a decadal scale over the past 1200 years. A dry period from ad 800 to 1000 that corresponds to the Medieval Warm Period' (WMP) is inferred from sedimentological analysis. The high content of carbonate recorded in this period suggests a dry phase, when the ratio of evaporation/precipitation was high. During this period the island was dominated by thermophilous and drought-tolerant taxa, such as Quercus ilex, Olea, Pistacia and Juniperus. A marked shift in the sediment properties is recorded at ad 1000, when carbonate content became very low suggesting wetter conditions until ad 1850-1900. Broadly, this period coincides with the Little Ice Age' (LIA), which was characterized by wetter and colder conditions in Europe. During this time rather mesic conifers (i.e. Pinus pinaster), shrubs and herbs (e.g. Erica arborea and Selaginella denticulata) expanded, whereas more drought-adapted species (e.g. Q. ilex) declined. Charcoal data suggest enhanced fire activity during the LIA probably as a consequence of anthropogenic burning and/or more flammable fuel (e.g. resinous Pinus biomass). The last century was characterized by a shift to high carbonate content, indicating a change towards drier conditions, and re-expansion of Q. ilex and Olea. The post-LIA warming is in agreement with historical documents and meteorological time series. Vegetation dynamics were co-determined by agricultural activities on the island. Anthropogenic indicators (e.g. Cerealia-type, Sporormiella) reveal the importance of crops and grazing on the island.

Studies have shown that the processing of words violating OCP-Place is inhibited. Functionalists assume that OCP arises as a consequence of low-level perception: a consonant following another with the same [place] cannot be faithfully perceived as an independent unit. If functionalist theories were correct, then lexical access would be inhibited if two homorganic consonants conjoin at word boundaries-a problem that can only be solved with lexical feedback. Here, we experimentally challenge the functional account by showing that OCP-Place can be used as a speech segmentation cue during pre-lexical processing without lexical feedback, and that the use relates to distributions in the input. In Experiment 1, native listeners of Dutch located word boundaries between two labials when segmenting an artificial language. This indicates a use of OCP-Labial as a segmentation cue, implying a full perception of both labials. Experiment 2 shows that segmentation performance cannot solely be explained by well-formedness intuitions. Experiment 3 shows that knowledge of OCP-Place depends on language-specific input: in Dutch, co-occurrences of labials are under-represented, but co-occurrences of coronals are not. Accordingly, Dutch listeners fail to use OCP-Coronal for segmentation.}, language = {en} } @misc{WattendorfFestmanWestermannetal.2012, author = {Wattendorf, Elise and Festman, Julia and Westermann, Birgit and Keil, Ursula and Zappatore, Daniela and Franceschini, Rita and Luedi, Georges and Radue, Ernst-Wilhelm and M{\"u}nte, Thomas F. and Rager, G{\"u}nter and Nitsch, Cordula}, title = {Early bilingualism influences early and subsequently later acquired languages in cortical regions representing control functions}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {384}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-404092}, pages = {19}, year = {2012}, abstract = {Early acquisition of a second language influences the development of language abilities and cognitive functions. In the present study, we used functional Magnetic Resonance Imaging (fMRI) to investigate the impact of early bilingualism on the organization of the cortical language network during sentence production. Two groups of adult multilinguals, proficient in three languages, were tested on a narrative task; early multilinguals acquired the second language before the age of three years, late multilinguals after the age of nine. All participants learned a third language after nine years of age. Comparison of the two groups revealed substantial differences in language-related brain activity for early as well as late acquired languages. Most importantly, early multilinguals preferentially activated a fronto-striatal network in the left hemisphere, whereas the left posterior superior temporal gyrus (pSTG) was activated to a lesser degree than in late multilinguals. The same brain regions were highlighted in previous studies when a non-target language had to be controlled. Hence the engagement of language control in adult early multilinguals appears to be influenced by the specific learning and acquisition conditions during early childhood. Remarkably, our results reveal that the functional control of early and subsequently later acquired languages is similarly affected, suggesting that language experience has a pervasive influence into adulthood.

In Study 1, 92 participants read a vignette about a nonconsensual sexual encounter and rated whether it was a sexual assault and how much the woman was to blame. In the scenario, the man either used physical force or offered alcohol to the woman to overcome her resistance. Rape myth acceptance (RMA) was measured as an individual difference variable. Participants were more convinced that the incident was a sexual assault and blamed the woman less when the man had used force rather than offering her alcohol. In Study 2, 164 college students read a scenario in which the woman rejected a man's sexual advances after having either accepted or turned down his offer of alcohol. In addition, the woman was either portrayed as being sexually attracted to him or there was no mention of her sexual interest. Participants' RMA was again included. High RMA participants blamed the victim more than low RMA participants and were less certain that the incident was a sexual assault, especially when the victim had accepted alcohol and was described as being sexually attracted to the man. The findings are discussed in terms of their implications for the prevention and legal prosecution of sexual assault.}, language = {en} } @misc{ProtGentileAndersonetal.2013, author = {Prot, Sara and Gentile, Douglas A. and Anderson, Craig A. and Suzuki, Kanae and Swing, Edward and Lim, Kam Ming and Horiuchi, Yukiko and Jelic, Margareta and Krah{\´e}, Barbara and Liuqing, Wei and Liau, Albert K. and Khoo, Angeline and Petrescu, Poesis Diana and Sakamoto, Akira and Tajima, Sachi and Toma, Roxana Andreea and Warburton, Wayne and Zhang, Xuemin and Lam, Ben Chun Pan}, title = {Long-term relations among prosocial-media use, empathy, and prosocial behavior}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {389}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-404136}, pages = {11}, year = {2013}, abstract = {Despite recent growth of research on the effects of prosocial media, processes underlying these effects are not well understood. Two studies explored theoretically relevant mediators and moderators of the effects of prosocial media on helping. Study 1 examined associations among prosocial- and violent-media use, empathy, and helping in samples from seven countries. Prosocial-media use was positively associated with helping. This effect was mediated by empathy and was similar across cultures. Study 2 explored longitudinal relations among prosocial-video-game use, violent-video-game use, empathy, and helping in a large sample of Singaporean children and adolescents measured three times across 2 years. Path analyses showed significant longitudinal effects of prosocial- and violent-video-game use on prosocial behavior through empathy. Latent-growth-curve modeling for the 2-year period revealed that change in video-game use significantly affected change in helping, and that this relationship was mediated by change in empathy.}, language = {en} } @misc{BieneckKrahe2017, author = {Bieneck, Steffen and Krah{\´e}, Barbara}, title = {Blaming the victim and exonerating the perpetrator in cases of rape and robbery: is there a double standard?}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-402907}, pages = {13}, year = {2017}, abstract = {Research in legal decision making has demonstrated the tendency to blame the victim and exonerate the perpetrator of sexual assault. This study examined the hypothesis of a special leniency bias in rape cases by comparing them to cases of robbery. N = 288 participants received descriptions of rape and robbery of a female victim by a male perpetrator and made ratings of victim and perpetrator blame. Case scenarios varied with respect to the prior relationship (strangers, acquaintances, ex-partners) and coercive strategy (force vs. exploiting victim intoxication). More blame was attributed to the victim and less blame was attributed to the perpetrator for rape than for robbery. Information about a prior relationship between victim and perpetrator increased ratings of victim blame and decreased perceptions of perpetrator blame in the rape cases, but not in the robbery cases. The findings support the notion of a special leniency bias in sexual assault cases.}, language = {en} }
