The research question of the thesis is “How did al-Waṭwāṭ reconcile the moralism and real politikal interest inside the relationships of loyalty in his letters?”. The thesis first reviews various academic works and arguments on loyalty into four categories based on historical periods and disciplines and the historical background of al-Waṭwāṭ and Anūshtakīnid Khwārazm, then studies the narrative of al-Waṭwāṭ on three types of relationships of loyalty, which are respectively the relationships of loyalty between the populace and the rulers, the relationships of loyalty between the officials and the rulers, and the relationships of loyalty between rulers.Show less

Although previous research proposed that the heightened arousal experienced by bystanders during dangerous incidents with in-group victims leads to increased assistance, empirical evidence supporting this claim remains limited and difficult to be studied with self-report measurements. This study addresses these limitations by employing the biopsychological model of challenge and threat (BPS-CT) to examine empirically the physiological reactions of bystanders. Participants were exposed to vignettes describing dangerous and non-dangerous incidents involving in-group and out-group victims, while their cardiovascular activity and blood pressure were measured. The presence of bystanders was found to have a marginal impact on reducing threat among bystanders, irrespective of the incident's severity. Moreover, in dangerous incidents, the presence of other bystanders and a shared in-group identity with the victim heightened participants' sense of challenge. The findings align with previous meta-analytic evidence, highlighting that bystanders are more likely to intervene in dangerous situations. The results are discussed and possible implications are proposed for designing intervention programs aimed at increasing bystander intervention rates.Show less

These range from large mass graves, such as Vianen and Den Bosch, where the remains of 60-80 individuals were found, to individual field graves. Surprisingly, the mass graves have produced little material culture. Interestingly, both mass graves can be connected to military hospitals, which explains why the dead were buried without any personal affects. In contrast, the dune region of Noord-Holland has brought forth about fifteen shallow field graves where the skeletal remains were accompanied with a large amount of artefacts. These graves were hastily dug nearby where the soldiers had died. The graves have been connected to the Anglo-Russian Invasion of 1799, which was part of the War of the Second Coalition. During which the British and Russian tried to invade the Batavian Republic, which had been founded in 1795 with the aid of Revolutionary France. However, this assistance came at a cost, which meant that the Batavian Republic was actually a vassal state of France. However, while the soldiers of Noord-Holland were found with large amount of material culture, it has become clear that it is difficult to properly identify the soldiers, as very specific artefacts need to be preserved for the possibility of any identification. This includes buttons, dress accessories and insignia with the number of the military unit. In the case-studies, the cases of five Batavian soldiers found at sites Grote Kaap and Drooghe Weert are discussed. Multiple individuals were found with buttons with a ‘3’, which has previously been identified as belonging to Batavian soldiers of the 3rd Half Brigade. However, due to changes in uniform regulations, the number might also signify the number of the battalion instead, which makes the identification more complicated. Thus, a new methodology was created to help identify the remains of the Batavian soldiers (and Napoleonic soldiers in general), with specific focus on their nationality and military unit. The methodology combined uniformology and surviving uniforms from the collection of the Dutch National Military Museum, which were then compared with the historical sources of the Anglo-Russian Invasion of 1799. In summary, the combination of historical sources, uniformology, and surviving uniforms made it possible to make an accurate reconstruction of the circumstances surrounding the death of the Batavian soldiers. By using the Napoleonic collection of the Dutch National Military Museum as a reference, it was possible to identify the remains of several clothing items. This gave new ideas about the process of looting the dead as clear evidence was found, as several items were surprisingly missing. Furthermore, it revealed new insights on the mentality of Batavian soldiers surrounding death, burial and mortality.Show less

These isotopes are regularly measured in the non-organic component of tooth enamel, which is highly resistant to diagenetic alteration. Likewise, δ15N can be used to reconstruct trophic level and food webs. Up until recently, δ15N could only be measured on relatively young samples (<100,000 years old), because it requires organic material, usually bone collagen or dentin, which rarely preserves in the fossil record. However, in 2021, an oxidation-denitrification method was developed. This method allows for the measurement of the nitrogen isotopic composition of the organic material trapped in the crystalline structure of (fossil) tooth enamel. Thus, we can now measure δ13C, δ15N, and δ18O on the same aliquot of tooth enamel. Here, combined δ13C, δ15N, and δ18O isotope data from tooth enamel of 14 serially-sampled fossil equid (Equus sp.) third molars from the ~120,000-year-old Middle Paleolithic Neanderthal site of Neumark-Nord 2, Germany, is presented. Each tooth was sampled along the growth axis and yielded up to 26 sub-samples (total n = 259). Neumark-Nord is a well-preserved archaeological site with a rich vertebrate fauna. It has yielded a large isotopic dataset, which includes some of the oldest stable carbon and nitrogen isotope measurements on bone collagen. This study allows us to expand the isotopic dataset of Neumark-Nord 2 by serially-sampled data, which enables us to reconstruct seasonality for the Last Interglacial (Eemian; MIS 5e/5d transition). δ13C and δ18O of all enamel samples (n = 259) was measured using the cold trap method. Based on these isotope patterns, 72 samples (including all serial measurements of three of the equid teeth) were selected for δ15N measurement, to assess potential seasonal variation in the δ15N values of the enamel. The enamel δ13C, δ15N, and δ18O results are consistent with previously published equid collagen δ13C, δ15N, and bulk enamel δ18O values. A clear seasonal signal is present in the δ18O values of each tooth, with higher values in summer than in winter. This seasonal signal is absent in both the δ13C and δ15N values. This study shows that there is no strong effect of seasonal variation detectable in the δ15N values of nitrogen isotopes in the enamel of equids in temperate environments. This suggests that, in order to measure an accurate average δ15N value, bulk samples of tooth enamel from equids – and likely other large herbivores – in temperature environments do not need to cover an entire year of growth. In addition, the correlation observed between δ13C and δ15N enamel values seems to indicate that, in such environments, the mechanisms controlling carbon and nitrogen isotope fractionation are positively related. Lastly, this study improves the time-resolution of the Neumark-Nord 2 isotopic dataset, allowing for a better reconstruction of the past ecosystem by providing seasonal data.Show less

And how does our soul affect our behaviour? These are questions that have occupied us since the dawn of time. This thesis explores the ways in which Middle Platonist thinkers of the second century AD in particular approach such questions of good moral behaviour. As it turns out, these thinkers tend to focus on the human soul and its constitution in order to tackle moral conundrums. Therefore, the research question this thesis aims to answer is as follows: how do the Middle Platonists of the second century AD use the structure of the human soul in order to enforce practical ethics? By examining the works of Maximus of Tyre, Alcinous, and Galen – authors active in different genres within the Middle Platonic philosophical movement – through the lenses of both ancient psychology as well as ancient moral psychology, this thesis aims to advocate for the presence of a methodology of psychological morality in Middle Platonism: the structure of the human soul is noticeably being used in order to enforce ideal behaviour.Show less

As a manipulation, parents were instructed to provide their children (N=79), aged 10-14 years, with standardized verbal threat or safety information about two strangers in the lab. Then, children engaged in a social interaction task with the two strangers (blind to their condition) separately, while child behavioral avoidance was recorded. Following the task, children reported fear beliefs for each stranger. Also, parents completed a self-report questionnaire on social anxiety symptoms. Children reported more fear beliefs for the stranger paired with the threat information, but no significant difference was found in observed avoidance. In addition, verbal threat information did not have a stronger influence on children’s observed avoidance in case of higher reported fear beliefs. Similarly, high parental social anxiety symptoms did not moderate the impact of verbal threat information on the child’s cognitive or behavioural fear indices. However, they did have a significant influence on behavioural avoidance, regardless of verbal information. Overall, this study shows a causal effect of verbal threat messages provided by parents only on child subjective fear and highlightsthe need for further research on the verbal transmission of childhood social fears in the context of family, by examining these processes in various social situations, age groups, and fear indices.Show less

Rooted in Roman traditions, these ceramics were produced in specialized potters workshops of which the majority was located along the rivers Rhine and Meuse. Another group of pottery, the handmade ceramics, however, are often given less attention. These handmade pots have often been perceived and described by archaeologists as rudimentary, poorly made and of low quality. In addition, they have been associated with Germanic culture. This is often followed by the assumption that this type of pottery is, in stark contrast to the wheel-thrown ceramics, made by unskilled potters, and therefore made locally on an occasional level in a household setting by woman and children. These claims are however based on modern assumptions only, since the production aspects of these handmade ceramics have hardly been studied. Furthermore, they show a strong bias that is rooted in our history with the industrial revolution and capitalism, and in value-associations and preconceptions regarding Roman and Germanic culture. The way archaeologists perceive and value these handmade ceramics should therefore not be mistaken for the perception and valuation of these ceramics by the early medieval societies that created and used them. By using an integrated chaîne opératoire approach that considers the technological, social and symbolic dimension of the production of ceramic vessels, this thesis attempts to gain insights on the production, perception and value of these handmade ceramics in the early medieval societies of Northern-Gaul. The ceramic assemblage of the recently excavated Merovingian cemetery of Nijmegen-Lentseveld (The Netherlands) was chosen as a case-study. At this site, roughly dating to the 6th century, an notably high concentration of handmade ceramics was found, together with well-known wheel-thrown vessels. This provided the unique opportunity to study both handmade and wheel-thrown ceramics together. A technological analysis, using a combination of macroscopic-, petrographic- and chemical techniques, was performed on the Lentseveld assemblage as well as on several local reference ceramics and clay samples. The results show that the production of the handmade ceramics found at the cemetery of Nijmegen-Lentseveld, was more complex than the assumed local household production. It is demonstrated that a large majority of the handmade ceramics from the site were made with a clay with very similar properties, that does not match with the clay samples collected in the vicinity of the site, nor with the known local ceramic productions. Although it was not possible to conclude with certainty whether the exact same clay source was used to create all ceramics and determine the location of such clay source, it can be concluded that the clay most likely was collected further away from the site and should be sought at a more regional level. The fact that there appears to be a consensus on the type of clay deemed suitable to create these ceramics and a similar or the same clay source was used for a large group of handmade ceramics, suggest the clay collection was rather well organized. This contradicts the previous assumptions of local household production whereby each household collects their own clay at a source near their house. The integrated chaîne opératoire approach used in this thesis has furthermore shown that production entails more than just technological actions, and also has a strong social and symbolic dimension. It uncovered the many material-, social – and imagined values that could have been associated with (the production of) handmade ceramics, such as the act of crafting itself, the transformation by fire and the value of materials. This shows that the perception and values attributed handmade ceramics by the early medieval societies of Northern Gaul who created and used them were mostly likely very different from negative perception and values projected onto these ceramics by archaeologists. This thesis therefore shows that there is a strong need for a re-evaluation and foremost a re-valuation of these handmade ceramics, and has taken the first step in doing so by taking a different approach to analysing them with the help of a case-study.Show less

This sort of behavioural variability has been attributed to exploration during the choice process and has been linked to the locus coeruleusnoradrenaline (LC-NA) system. A recent computational account implementing a “noisy” reinforcement learning (RL) model provides evidence that computational imprecision during the learning process contributes to behavioural variability in decision-making as well. In the present study, the role of the LC-NA system in modulating learning imprecision has been investigated, using a multi-modal approach including the newly developed noisy RL model, a double-blind pharmacological manipulation, and EEG. The responses of thirty participants in a decision-making task were investigated during two experimental sessions in which either atomoxetine, a NA reuptake inhibitor, or placebo was administered, and the model fit of the noisy RL model was tested against the classical RL model without learning imprecision parameter. Contrary to our expectations, we did not find evidence for a modulatory role of the LC-NA system of learning imprecision. However, in line with our expectations, increased NA levels did not impact exploratory behaviour either. Crucially, the noisy RL model outperformed the classical RL model assuming exact learning and learning imprecision led to a significant number of non-maximising decisions contributing to behaviour variability. Moreover, the exploratory EEG analyses on potential underlying mechanisms of learning imprecision suggest learning noise to emerge broadly during feedback processing, rather than within a certain time window. The current study provides further evidence for the importance of computational imprecision during value-based learning.Show less

Yet, the symptom interrelations between PTSD and dissociation have not been disentangled. The timing and type of traumatic events have been suggested to play crucial roles in the comorbidity between PTSD and dissociative symptoms. Therefore, partial correlations between PTSD, dissociative symptoms, and adverse childhood maltreatment (ACE) were investigated in two regularized partial correlation networks. Online self-report responses from participants (N = 495) of an overarching study on domestic violence were used. Symptoms and maltreatment types were assessed with the Post-Traumatic Stress Disorder Checklist DSM-5, the Dissociation Experience Scale-II, and the Childhood Trauma Questionnaire-Short Form. The first network analysis included nine nodes (four PTSD symptoms, three dissociation symptoms, two assumed confounders). The second analysis additionally considered five ACE types. The network exploration revealed few and weak connections between PTSD and dissociation. Regardless of the bridge strength, absorption/imagination and hyperarousal showed to be hubs linking PTSD and dissociative symptoms. Adding ACE barely changed the bridges between PTSD and dissociative symptoms. Amnesia appeared to be a hub for connecting dissociative symptoms to ACE. Emotional abuse was the only maltreatment type connected to the PTSD symptoms. These preliminary findings suggest that PTSD and dissociation are largely independent constructs and hint towards separate diagnostic entities. The study was limited by the sample’s subclinical symptoms and maltreatment scores. This limitation may also be partly responsible for the poorly connected network. Prospective studies with clinical samples are needed to further investigate the interplay between PTSD, dissociation, and ACE.Show less

Research suggests that nocebo information may improve some outcomes in non-cancer settings, but its effectiveness on psychological outcomes in cancer settings remains uncertain. Clinician-expressed empathy has repeatedly been shown to improve short-term psychological outcomes in cancer patients, although the long-term effects require further investigation. Moreover, potential interaction effects between nocebo information and clinician-expressed empathy observed in non-cancer settings warrant exploration in cancer care. Objective: To investigate the distinct and combined effects of nocebo information and clinician-expressed empathy on breast cancer patients’ psychological outcomes (main outcome: state anxiety) over time and at short term when undergoing chemotherapy. Methods: In this 2x2 clinical proof-of-principle randomized controlled trial, female breast cancer patients undergoing chemotherapy for the first time viewed 1 out of 4 role-played information videos, wherein the levels of nocebo information (present vs. absent) and empathy (present vs. absent) were varied. Using stepwise multilevel analyses and two-way analyses of variance, we investigated the videos’ effects on participants’ psychological outcomes over time and at short term. Results: Among the 19 participants, over time, nocebo information showed trends (p > .05) to improve state anxiety but worsen self-efficacy and distress, and empathy showed trends to worsen state anxiety, self-efficacy, as well as distress. When combined, nocebo information and empathy significantly and largely worsened self-efficacy (β = -3.21; p = .009). At short term, both nocebo information and empathy showed trends (p > .05) to worsen feelings of satisfaction and trust. Conclusion: Although these unexpected and mixed findings are preliminary, they highlight the need to fully understand the potential benefits and risks associated with clinician-patient communication strategies in cancer care.Show less

The present study investigated whether individual differences in late L2 acquisition could be explained by individual differences in musical experience, because a large number of prior studies showed that musicians have enhanced auditory processing abilities. Dutch late-learners of English performed an AXB identification task, a 4I2AFC discrimination task and a passive oddball task with the English vowel contrast DRESS-TRAP. Data was analyzed with a multilevel single-trial approach to focus on the explanation of individual differences. The results showed large individual differences in all three tasks, good behavioral discrimination of the vowel contrast, and a large mismatch negativity (MMN) effect. A relation between discrimination performance and the variables musical experience and MMN amplitude was found, indicating that better behavioral discrimination of small acoustic differences was related to more musical experience and larger MMN differences. The absence of a similar relation with identification performance was attributed to a ceiling effect and restricted range of results on this task. The fact that no significant relation was found between musical experience and MMN amplitude, was explained by the required discrimination difficulty to measure a positive effect of musical experience, which was not met by the stimuli in the oddball task.Show less

Additional research is necessary to confirm effects and shed light on experimental and interindividual differences and those related to various mechanisms underlying cognitive processes. This study aimed to assess the influence of microgravity on the neurocognitive marker P3 during parabolic flight. METHODS: Participants were trained to perform a brain-computer interface (BCI) task, which included a visual oddball paradigm task. Nine participants performed this task during parabolic flight. Statistic analyses assessed the amplitude and latency of the P3 event-related potential (ERP). RESULTS: Results revealed no significant differences for P3 Amplitude nor Latency in the 0G condition versus the 1G condition. The amplitude for oddball stimuli was significantly higher than the amplitude for standard stimuli in both 1G and 0G. CONCLUSION: There needs to be greater consensus and understanding concerning the effects of microgravity on cognitive performance and ERPs. The data presented here does not verify that short bouts of microgravity could enhance nor diminish neuro-behavioral performance. It does confirm that the visual-based oddball paradigm is feasible in microgravity conditions.Show less

This study fills a research gap by being the first to directly compare two contemporary imagery script procedures to evaluate their feasibility. We hypothesized an audio-scripted imagery procedure to lead to higher fear expression (heart rate, skin conductance, subjective distress) than an imagery-only script. A moderating effect of the vividness of the stressful memory on fear expression was also hypothesized. In a between-subjects design, participants (N = 37) were sorted into two conditions and were interviewed regarding a stressful life experience. Fear expression was measured during baseline and imagery. Contrary to expectations, both procedures led to a similar increase in fear expression. Crucially, the audio-scripted imagery procedure might be especially effective for participants with a high baseline vividness of the stressful memory which has implications for future PTSD research. Upcoming studies should investigate changes to the script procedures to facilitate comparison between scripts and further explore the effect of script procedures on high-vividness participants.Show less

These two pairs of vowels – which differ in their height and ATR (‘advanced tongue root’) value – are notoriously difficult to tell apart acoustically, and their pronunciation varies considerably between languages and even speakers. Moreover, previous studies have only focused on how to distinguish these vowels in languages with both pairs; in languages with just one pair, how do we know if that pair is [ɪ ʊ] or [e o]? To address this gap, the main acoustic study of this thesis looks at data from Boa-Leboale, a Bantu language spoken in the Democratic Republic of the Congo that has historically been described as only having [ɪ ʊ], not [e o]. Using the results and acoustic methodology of Starwalt’s (2008) landmark study, I construct a number of hypotheses to test two research questions; research question (I) investigates whether Boa-Leboale has one or two pairs of vowels and research question (II) attempts to identify whether a given set of vowels is more likely to be [ɪ ʊ] or [e o]. The results of this study indicate that Boa-Leboale does indeed have only one pair of vowels, and those vowels are most likely [ɪ ʊ], as suggested by previous descriptions. Given this promising result, I hope that further studies will be able to improve on the study presented here and solve the issue of identifying these vowels acoustically not just for Boa-Leboale, but for any language.Show less

These expectations were largely grounded in Khatami’s rhetoric of social justice and the promises of more socio-political and cultural freedoms that he voiced during his electoral campaign. In practice, however, these promises did not materialise and disappointed workers and students alike. Khatami continued the economic neoliberalisation that his predecessor Rafsanjani (r. 1989-1997) had begun and the supreme leader, Khamenei (r. 1989-), heavily resisted his attempts to create more relaxed academic settings. Although the existing literature explains why Khatami and Khamenei, which respectively represented the reformist and conservative sides of the political spectrum, embraced different labour policy-paths, it does not seek to understand how both officials constructed their social reality such that it made sense for them to do so. Presuming that the meaning of political factions is objectively defined, the literature therefore foregoes enquiring after the discursive context in which they constructed their ideologies and how these related to their policy-paths. However, as policies do not originate in an intellectual and institutional vacuum but are made possible in a political context where competing discourses interact, examining them from a discursive perspective clarifies how rather than why these officials perceived them as meaningful paths to pursue. This focus on ideology construction then leads to enquiring how both constructed Iran’s identity and, by implication, that of workers and students. Taking a poststructuralist approach, this thesis therefore enquires how Khatami’s and Khamenei’s evolving discursive negotiation on Iranian identity was co-constitutionally related to the approved labour policies that concerned workers and students during Khatami’s presidency (r. 1997-2005).Show less

Zhang Shi learning provides an alternative to statism Wang Anshi 王安石 (1021-1086) learning in the Northern Song (960-1127) and typical Neo-Confucianism represented by Zhu Xi and Lu Jiuxuan 陸九淵 (1139-1191) in Southern Song (1127-1279) , which is based on local spontaneous elites and emphasizes the role of society and local volunteerism. The social origin and foundation of this transitional Neo-Confucianism was the former (potential) capital bureaucratic family who were exiled due to the fall of the Northern Song. They took the northern expedition to return to the capital as their goal and gave up the run of their hometowns and the local communities in which they lived. They were skeptical of Zhu Xi’s social program, such as the community compacts (xiangyang 鄉約), the community granaries (shecang 社倉) and private commercial publishing, which later became the typical behavior of Neo-Confucian. Based on the ideas of Mencius (Mengzi 孟子), Zhang Shi developed the theory of “spontaneous disinterestedness” (wu suowei er ran 無所為而然), which underpinned his ideas on the distinction between righteousness/public/king and profit/selfish/hegemon. Though Zhang learning relied on the state, it cut sharply with Wang learning in the aspect of “motivation”. For Zhang, the power of the state was not an end in itself, but rather the state should be consistent with the spontaneous disinterestedness from the heavenly principle. With a particular emphasis on military-fiscal skills, Zhang and his disciples sought to take over the state apparatus left behind by Wang Anshi’s reforms and to make this state act out of righteousness in the hands of Neo-Confucianism gentlemen. Zhang and his disciples proposed and participated in all the northern expeditions during the Southern Song period. However, the northern capital could never be returned, and the number of exiled bureaucrats who were the social base of Zhang learning (and of the Huxiang 湖湘 school in general) dwindled over time. Zhu Xi, who came from a family of low-ranking exiled bureaucrats, found a new world in the local community in the south, and endeavored to transform himself into a member of the local elite, stepping out from behind Zhang Shi. After Zhang’s death, the local students he left behind in Hunan 湖南 and Sichuan 四川 were eventually aborted by the emerging typical Neo-Confucianism (Zhu Xi and Lu Jiuyuan school) that spoke for the local elites. Zhang as a kind of transitional Neo-Confucianism eventually faded from history, completing the transition from the Northern Song learning to the later typical Neo-Confucianism. By reframing this transitional and alternative Neo-Confucianism, this thesis refines the Hymes-Bol’s localism paradigm about the explanation of why and how Neo-Confucianism raised.Show less

In contrast, subanesthetic doses of ketamine show acute antidepressant effects. Previous functional connectivity findings implicate the ventromedial prefrontal cortex (vmPFC) and posterior cingulate cortex (PCC), key areas of the default mode network (DMN), in ketamine’s acute antidepressant effect. In addition, psilocybin has also shown acute antidepressant effects with a potential role for the claustrum, an area functionally connected to the DMN. However, pharmacological fMRI findings concerning acute antidepressant drug action may be moderated by the decision to include or exclude a controversial preprocessing step called global signal regression (GSR). In this study, we investigated ketamine’s acute effects on functional connectivity patterns in the brain in order to probe the underlying mechanism of its acute antidepressant effects. Hypotheses: Ketamine acutely decreases functional connectivity between the vmPFC and PCC and between the DMN and claustrum. In addition, these findings will not be affected by the decision to include or exclude GSR. Method: Twenty volunteers were administered ketamine as well as a placebo on separate days in a randomized, double-blind, crossover design. We acquired resting-state functional magnetic resonance imaging (fMRI) data before, during and immediately after the acute phase of administration. Results: No differences in functional connectivity patterns were found between ketamine and placebo. These results were unaffected by the inclusion or exclusion of GSR. Conclusion: It remains unclear which changes in functional connectivity occur in the acute phase of ketamine administration. Future research should investigate the influence of GSR on fMRI findings.Show less
