Political Humor as a confrontational tool against the Syrian regime: A study case: Syria, 15th March 2011 – 15th May 2012

The aim of this working paper is to analyze the inclusion of political humor into the set of actions used by opponents to the Syrian regime during the first year of a state-wide uprising in 2011. The research argues that although political humor has traditionally been seen mainly as a concealed voice against dominant elites, it can nevertheless take a confrontational stance and challenge a regime. In this paper we assess the role of political humor in challenging the legitimacy of the Syrian State through the battle for the signification of events. We will work with a theoretical framework that draws its assumptions from social movements’ studies and cultural studies. Through the assessment of the importance of discourse and the role of ideological domination to a regime we will see how the first year of the Syrian uprising included widespread acts of political humor as part of the strategy against the regime.

Impaired antibody memory to varicella zoster virus in HIV-infected children: low antibody levels and avidity*.

OBJECTIVE: HIV-infected children have impaired antibody responses after exposure to certain antigens. Our aim was to determine whether HIV-infected children had lower varicella zoster virus (VZV) antibody levels compared with HIV-infected adults or healthy children and, if so, whether this was attributable to an impaired primary response, accelerated antibody loss, or failure to reactivate the memory VZV response. METHODS: In a prospective, cross-sectional and retrospective longitudinal study, we compared antibody responses, measured by enzyme-linked immunosorbent assay (ELISA), elicited by VZV infection in 97 HIV-infected children and 78 HIV-infected adults treated with antiretroviral therapy, followed over 10 years, and 97 age-matched healthy children. We also tested antibody avidity in HIV-infected and healthy children. RESULTS: Median anti-VZV immunoglobulin G (IgG) levels were lower in HIV-infected children than in adults (264 vs. 1535 IU/L; P<0.001) and levels became more frequently unprotective over time in the children [odds ratio (OR) 17.74; 95% confidence interval (CI) 4.36-72.25; P<0.001]. High HIV viral load was predictive of VZV antibody waning in HIV-infected children. Anti-VZV antibodies did not decline more rapidly in HIV-infected children than in adults. Antibody levels increased with age in healthy (P=0.004) but not in HIV-infected children. Thus, antibody levels were lower in HIV-infected than in healthy children (median 1151 IU/L; P<0.001). Antibody avidity was lower in HIV-infected than healthy children (P<0.001). A direct correlation between anti-VZV IgG level and avidity was present in HIV-infected children (P=0.001), but not in healthy children. CONCLUSION: Failure to maintain anti-VZV IgG levels in HIV-infected children results from failure to reactivate memory responses. Further studies are required to investigate long-term protection and the potential benefits of immunization.

How Answers on Political Attitudes are Shaped by Interviewers: Evidence from a Panel Survey

We analyze whether the interviewers' political opinions have an influence on those of the respondents. The research uses data from a panel survey in which interviewers are randomly assigned to respondents. The results show that the respondents express significantly similar opinions to those of the interviewers in all questions considered. Multilevel models show that more educated respondents are affected to a slightly higher extent and that the interviewer's experience is also a factor. There is no difference between different respondent subgroups or when both interviewers and respondents share the same socio-demographic characteristics. While there is no evidence for respondents wanting to please the interviewers, the hypothesis of socially desirable behavior can indeed be confirmed.

Simultaneous co-expression of memory- and effector-related genes by individual human CD8 T cells depends on antigen specificity and differentiation

Purpose/Objective: Phenotypic and functional T cell properties are usually analyzed at the level of defined cell populations. However, large differences between individual T cells may have important functional consequences. To answer this issue, we performed highly sensitive single-cell gene expression profiling, which allows the direct ex vivo characterization of individual virus- and tumor-specific T cells from healthy donors and melanoma patients. Materials and methods: HLA-A*0201-positive patients with stage III/ IV metastatic melanoma were included in a phase I clinical trial (LUD- 00-018). Patients received monthly low-dose of the Melan-AMART- 1 26_35 unmodified natural (EAAGIGILTV) or the analog A27L (ELAGIGILTV) peptides, mixed CPG and IFA. Individual effector memory CD28+ (EM28+) and EM28- tetramer-specific CD8pos T cells were sorted by flow cytometer. Following direct cell lysis and reverse transcription, the resulting cDNA was precipitated and globally amplified. Semi-quantitative PCR was used for gene expression and TCR BV repertoire analyses. Results: We have previously shown that vaccination with the natural Melan-A peptide induced T cells with superior effector functions as compared to the analog peptide optimized for enhanced HLA binding. Here we found that natural peptide vaccination induced EM28+ T cells with frequent co-expression of both memory/homing-associated genes (CD27, IL7R, EOMES, CXCR3 and CCR5) and effector-related genes (IFNG, KLRD1, PRF1 and GZMB), comparable to protective EBV- and CMV-specific T cells. In contrast, memory/homing- and effectorassociated genes were less frequently co-expressed after vaccination with the analog peptide. Conclusions: These findings reveal a previously unknown level of gene expression diversity among vaccine- and virus-specific T cells with the simultaneous co-expression of multiple memory/homing- and effector- related genes by the same cell. Such broad functional gene expression signatures within antigen-specific T cells may be critical for mounting efficient responses to pathogens or tumors. In summary, direct ex vivo high-resolution molecular characterization of individual T cells provides key insights into the processes shaping the functional properties of tumor- and virus-specific T cells.

Transitions in partnership and parental status, gender, and political and civic participation

Participation research has documented the effect of partner and parenthood status, thereby ignoring the dynamic aspect of status changes. Based on theoretical insights on changes in political resources and interest, this study looks at partnership and parenthood as dynamic characteristics. Using data from the Swiss Household Panel (SHP), it examines to what extent important life-cycle transitions in partnership and parental status influence various forms of political and civic participation and whether they affect men and women's participation differently. Our regression analyses reveal that particularly the entry into separation or divorce is a main key point driving change in political and civic participation. Its effect is also highly gendered. Following separation, women participate less in voting, whereas men's participation rates are not affected in a negative way. Separation even increases men's level of anticipated activism. Children entering or leaving the household do not seem to represent key points of change in political and civic participation of the couple. Yet, the transition to having school-aged children significantly increases some types of participation, at least for women.

On the significance of CD8 alpha alpha expression for T cell memory.

Longitudinal studies on the kinetics of viral antigen specific CD8 T cell responses have led to a model whereby a relatively small subset of the primary effector CD8 T cells expanding after the first week of acute viral infection initiate a program of cell survival and differentiation into long lived memory T cells. These T cells are then critical for maintaining protective immunity to subsequent viral infection. Recent observations, using fluorescent tetramers of the MHC class Ib molecule TL, link transient expression of CD8alphaalpha homodimers on expanding primary effector CD8 T cells to the generation of memory cells. At present it is controversial what the role of CD8alphaalpha is in the generation of memory CD8 T cells. The involvement of the high affinity CD8alphaalpha ligand, the TL molecule, is not understood either. However, evidence from two viral infection models in mice, including one paper in this issue of the European Journal of Immunology, suggest a role for CD8alphaalpha in this process and call for additional research focus into these issues.

In her post-doctoral research stay, Aina Gallego has conducted several research projects with the overarching theme of identifying the effects of contexts on political behavior. She has examined the effects of institutions, the economic situation, or local contexts on outcomes such as voter turnout, vote choice, and positions on salient issues. As detailed below, this work has been published in several journal articles in leading Political Science journals such as Comparative Political Studies, Political Behavior, and Electoral Studies (see attached documents). She has a forthcoming book with Cambridge University Press, the most prestigious book press in Political Science.She has also published book chapters and has several working papers. In addition to conducting her research, Aina has received extensive training in both substantive areas and research methods. She has participated fully in the Department’s academic life by attending seminars and engaging in research projects with other members of the Department.

The political economy of childcare in OECD countries : Explaining cross-national variation in spending and coverage rates

If childcare policy has become topical in most OECD countries over the last ten years or so, actual developments display huge cross-national variations. Countries like Sweden and Denmark spend around 2 per cent of GDP on this service, and provide affordable childcare places to most children below school age. At the other extreme, in Southern Europe, only around 10 per cent of this age group has access to formal daycare. Against this background, this article aims to account for cross-national variations in childcare services. It distinguishes two dependent variables: the coverage rate and the proportion of GDP spent subsidising childcare services. Using a mix of cross-sectional and pooled times-series methods, it tests a series of hypotheses concerning the determinants of the development of this policy. Its main conclusion for the coverage rate is that key factors are public spending and wage dispersion (both positive). For spending, key factors are the proportion of women in parliaments (positive) and spending on age-related policies (negative).
