Early ship-based upper-air data and comparison with the Twentieth Century

Extension of 3-D atmospheric data products back into the past is desirable for a wide range of applications. Historical upper-air data are important in this endeavour, particularly in the maritime regions of the tropics and the southern hemisphere, where observations are extremely sparse. Here we present newly digitized and re-evaluated early ship-based upper-air data from two cruises: (1) kite and registering balloon profiles from onboard the ship SMS Planet on a cruise from Europe around South Africa and across the Indian Ocean to the western Pacific in 1906/1907, and (2) ship-based radiosonde data from onboard the MS Schwabenland on a cruise from Europe across the Atlantic to Antarctica and back in 1938/1939. We describe the data and provide estimations of the errors. We compare the data with a recent reanalysis (the Twentieth Century Reanalysis Project, 20CR, Compo et al., 2011) that provides global 3-D data back to the 19th century based on an assimilation of surface pressure data only (plus monthly mean sea-surface temperatures). In cruise (1), the agreement is generally good, but large temperature differences appear during a period with a strong inversion. In cruise (2), after a subset of the data are corrected, close agreement between observations and 20CR is found for geopotential height (GPH) and temperature notwithstanding a likely cold bias of 20CR at the tropopause level. Results are considerably worse for relative humidity, which was reportedly inaccurately measured. Note that comparing 20CR, which has limited skill in the tropical regions, with measurements from ships in remote regions made under sometimes difficult conditions can be considered a worst case assessment. In view of that fact, the anomaly correlations for temperature of 0.3–0.6 in the lower troposphere in cruise (1) and of 0.5–0.7 for tropospheric temperature and GPH in cruise (2) are considered as promising results. Moreover, they are consistent with the error estimations. The results suggest room for further improvement of data products in remote regions.

Reconstructive Dreams: A Pragmatic Fantastic After Postmodernism

This dissertation focuses on the use of fantastic elements in the work of a young generation of writers which explore the possibilities of literary development after and beyond postmodernism. By overtly declaring the fictionality of their fantastic stories by means of frame narratives, texts like Jonathan Safran Foer’s Everything is Illuminated (2002), Michael Chabon’s The Amazing Adventures of Kavalier and Clay (2000), Mark Danielewski’s House of Leaves (2000), David Mitchell’s number9dream (2001) and Yann Martel’s Life of Pi (2001) reassess the communicative value of genre boundaries in an attempt to move beyond postmodern relativity and breakdown of communicability. This clear focus on pragmatic concerns marks a shift in the use of the fantastic which calls for a reconsideration of some of the general critical assumptions about the workings of the mode. Though the relation between reality and fiction remains a central issue, the main concern shifts away from such epistemological and ontological considerations, towards questions concerning the pragmatic function of literary fiction in general and different genres in particular. Instead of dwelling on the typically postmodern concerns about the fictionality of reality and the instability of meaning, the works under discussion emphasise the constructive role fiction plays in dealing with reality, the uses to which it can be put and the functions it fulfils in fashioning our being in the world. Drawing on Iser’s theory of the fictive, Irmtraud Huber therefore suggests a reconceptualisation of the fantastic mode, which newly foregrounds its underlying pragmatic structure. She bring this adapted understanding to bear in a close textual analysis of the above mentioned literary texts, with the aim to account for their use of the mode in their commitment to a larger literary endeavour of a new generation that engages with the inheritance of postmodernism and struggles to come into its own.

Repolitisations féministes et queer du cerveau

L’histoire des relations entre biologie et politique féministe est tendue et contradictoire. Cela paraît d’autant plus flagrant aujourd’hui à l’âge d’or des neurosciences qui ramènent les arguments de supériorité masculine, le caractère inéluctable des différences de genre et la prédominance de l’hétérosexualité à une affaire de cerveau. Dans cet article, nous analysons les points d’intersection propres aux sciences du cerveau et du féminisme. Ces deux champs de recherche entretiennent selon nous des rapports conflictuels mais parfois aussi productifs, y compris dans leurs rapports à l’activisme politique. Ces rapports peuvent être caractérisés en référence à trois directions de recherche principales : des « déstabilisations », des « reconstructions » et des « recontextualisations ». En guise de conclusion, nous terminons par quelques réflexions sur les conditions sociologiques de l’engagement dans une économie politique des neurosciences.[1] [1]Traduit de l’anglais par Marc Gagnepain. Pour une brève présentation de l’article et du dossier thématique dans lequel il s’inscrit, nous renvoyons le/la lecteur/trice à l’article introductif de Bovet, Kraus, Panese, Pidoux et Stücklin, « Les neurosciences à l’épreuve de la clinique et des sciences sociales.

Parsing for agile modeling

In order to analyze software systems, it is necessary to model them. Static software models are commonly imported by parsing source code and related data. Unfortunately, building custom parsers for most programming languages is a non-trivial endeavour. This poses a major bottleneck for analyzing software systems programmed in languages for which importers do not already exist. Luckily, initial software models do not require detailed parsers, so it is possible to start analysis with a coarse-grained importer, which is then gradually refined. In this paper we propose an approach to "agile modeling" that exploits island grammars to extract initial coarse-grained models, parser combinators to enable gradual refinement of model importers, and various heuristics to recognize language structure, keywords and other language artifacts.

Towards a taxonomy of common factors in psychotherapy-results of an expert survey

BACKGROUND: How change comes about is hotly debated in psychotherapy research. One camp considers 'non-specific' or 'common factors', shared by different therapy approaches, as essential, whereas researchers of the other camp consider specific techniques as the essential ingredients of change. This controversy, however, suffers from unclear terminology and logical inconsistencies. The Taxonomy Project therefore aims at contributing to the definition and conceptualization of common factors of psychotherapy by analyzing their differential associations to standard techniques. METHODS: A review identified 22 common factors discussed in psychotherapy research literature. We conducted a survey, in which 68 psychotherapy experts assessed how common factors are implemented by specific techniques. Using hierarchical linear models, we predicted each common factor by techniques and by experts' age, gender and allegiance to a therapy orientation. RESULTS: Common factors differed largely in their relevance for technique implementation. Patient engagement, Affective experiencing and Therapeutic alliance were judged most relevant. Common factors also differed with respect to how well they could be explained by the set of techniques. We present detailed profiles of all common factors by the (positively or negatively) associated techniques. There were indications of a biased taxonomy not covering the embodiment of psychotherapy (expressed by body-centred techniques such as progressive muscle relaxation, biofeedback training and hypnosis). Likewise, common factors did not adequately represent effective psychodynamic and systemic techniques. CONCLUSION: This taxonomic endeavour is a step towards a clarification of important core constructs of psychotherapy. KEY PRACTITIONER MESSAGE: This article relates standard techniques of psychotherapy (well known to practising therapists) to the change factors/change mechanisms discussed in psychotherapy theory. It gives a short review of the current debate on the mechanisms by which psychotherapy works. We provide detailed profiles of change mechanisms and how they may be generated by practice techniques.

Trade and Culture : Keep the Border Fuzzy, Please

The relationship between trade and culture can be singled-out and deservedly labelled as unique in the discussion of 'trade and ...' issues. The reasons for this exceptional quality lie in the intensity of the relationship, which is indeed most often framed as 'trade versus culture' and has been a significant stumbling block, especially as audiovisual services are concerned, in the Uruguay Round and in the subsequent developments. The second specificity of the relationship is that the international community has organised its efforts in a rather effective manner to offset the lack of satisfying solutions within the framework of the WTO. The legally binding UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions is a clear sign of the potency of the international endeavour, on the one hand, and of the (almost desperate) desire to contest the existing WTO norms in the field of trade and culture, on the other. A third distinctive characteristic of the pair 'trade and culture', which is rarely mentioned and blissfully ignored in any Geneva or Paris talks, is that while the pro-trade and pro-culture opponents have been digging deeper in their respective trenches, the environment where trade and cultural issues are to be regulated has radically changed. The emergence and spread of digital technologies have modified profoundly the conditions for cultural content creation, distribution and access, and rendered some of the associated market failures obsolete, thus mitigating to a substantial degree the 'clash' nature of trade and culture. Against this backdrop, the present paper analyses in a finer-grained manner the move from 'trade and culture' towards 'trade versus culture'. It argues that both the domain of trade and that of culture have suffered from the aspirations to draw clearer lines between the WTO and other trade-related issues, charging the conflict to an extent that leaves few opportunities for practical solutions, which in an advanced digital setting would have been feasible.

White claimants and the moral community of South African land restitution

South African land restitution, by way of which the post-apartheid state compensates victims of racial land dispossession, has been intimately linked to former homelands: prototypical rural claims are those of communities that lost their rights in land when being forcibly relocated to reserves and they now aspire to return to their former lands and homes from their despised ‘homelands’. However, white farmers, who were also dispossessed (although usually compensated) by the apartheid state in the latter’s endeavour to consolidate existing homelands, have lodged restitution claims as well. While the Land Claims Court has principally admitted such restitution claims and ruled upon the merits of individual cases, state bureaucrats, legal activists, as well as other members of the public have categorically questioned and challenged such claims to land rights by whites. Focussing on white land claimaints effected by the establishment of former KwaNdebele, this paper investigates the contested field of moral entitlements emerging from divergent discourses about the true victims and beneficiaries of apartheid. It pays particular attention to land claims pertaining to the western frontier of KwaNdebele – the wider Rust de Winter area, which used to be white farmland expropriated in the mid-1980s for consolidation (that never occurred) and currently vegetates as largely neglected no-man’s-(state-)land under multiple land claims. Being the point of reference for state officials, former white farmers, Ndebele traditionalists, local residents, and other citizens, this homeland frontier is hence analysed as a fateful zone of contestation, in which the terms of a new South African moral community are negotiated.

Dating polygenetic metamorphic assemblages along a transect across the Western Alps

Multichronometric analyses were performed on samples from a transect in the French-Italian Western Alps crossing nappes derived from the Briançonnais terrane and the Piemonte-Liguria Ocean, in an endeavour to constrain the high-pressure (HP) metamorphism and the retrogression history. 12 samples of white mica were analysed by 39Ar-40Ar stepwise heating, complemented by 2 samples from the Monte Rosa 100 km to the NE and also attributed to the Briançonnais terrane. One Sm-Nd and three Lu-Hf garnet ages from eclogites were also obtained. White mica ages decrease from ca. 300 Ma in the westernmost samples (Zone Houillère), reaching ca. 300 °C during Alpine metamorphism, to < 48 Ma in the internal units to the East, which reached ca. 500 °C during Alpine orogeny. The conventional “thermochronological” interpretation postulates Cretaceous Eo-Alpine HP metamorphism and younger “cooling ages” in the higher-temperature samples. However, Eocene Lu-Hf and Sm-Nd ages from the same samples cannot be interpreted as post-metamorphic cooling ages, which makes a Cretaceous eclogitization untenable. The age date from this transect require instead to replace conventional “thermochronology” by an approach combining age dating with detailed geochemical, petrological and microstructural investigations. Petrology reveals important mineralogical differences along the transect. Samples from the Zone Houillère mostly contain detrital mica. White mica with Si > 6.45 atoms per formula unit becomes more abundant eastward. Across the whole traverse, HP phengitic mica forms the D1 foliation. Syn-D2 mica is Si-poorer and associated with nappe stacking, exhumation, and hydrous retrogression under greenschist facies conditions. D1 phengite is very often corroded, overgrown or intergrown by syn-D2 muscovite. Most importantly, syn-D2 recrystallization is not limited to S2 schistosity domains; microchemical fingerprinting shows that it also can form pseudomorphs after crystals that could be mistaken to have formed during D1 based on microstructural arguments alone. Thereby the Cl concentration in white mica is a useful discriminator, since D2 retrogression was associated with a less saline fluid than eclogitization. Once the petrological stage is set, geochronology is straightforward. All samples contain mixtures of detrital, syn-D1 and syn-D2 mica, and retrogression phases (D3) in greatly varying proportions according to local pressure-temperature-fluid activity-deformation conditions. The correlation of age vs. Cl/K clearly identifies 47 ± 1 Ma as the age of formation of syn-D1 mica along the entire transect, including the Monte Rosa nappe samples. The inferred age of the greenschist-facies low-Si syn-D2 mica generation ranges within 39-43 Ma, with local variations. Coexistence of D1 and D2 ages, and the constancy of non-reset D1 ages along the entire transect, are strong evidence that the D1 white mica ages are very close to formation ages. Volume diffusion of Ar in white mica (activation energy E = 250 kJ/mol; pressure-adjusted diffusion coefficient D’0 < 0.03 cm2 s-1) has a subordinate effect on mineral ages compared to both prograde and retrograde recrystallization in most samples. Eocene Lu-Hf and Sm-Nd garnet ages are prograde and predate the HP peak.

Construction and first validation of the comprehensive inventory of mindfulness (CHIME)

Introduction: Measuring trait mindfulness and change in mindfulness may be a crucial prerequisite for the evaluation and further development of mindfulness based interventions for the treatment of mental disorders. This endeavour is nontrivial as current measures cover varying aspects and mindfulness and may have problems regarding validity. This presentation describes the development and validation of a questionnaire for the comprehensive assessment of mindfulness: the Comprehensive Inventory of Mindfulness Experiences (CHIME). Method: The factor structure, reliability, and validity of the CHIME were established in a community sample (N = 298) and a sample of MBSR group participants (N = 161). Results: Factor-analytical procedures supported an eight-factor structure. The structure was tested in a further confirmatory sample (N = 202). The questionnaire and its subscales exhibited good reliability (internal consistency and retest-reliability). Analysis of the measurement invariance of the single items over groups differing in age, gender, meditation experience, and symptom load pointed to the absence of systematic differences in the items' semantic understanding. Parameters reflecting construct validity, criterion validity, and incremental validity as well as change sensitivity were all at least satisfactory. Conclusions: The CHIME is a self-report measure with favorable psychometric properties based on all aspects of mindfulness that are included in current mindfulness scales. This scale may be helpful in the evaluation and further development of mindfulness based interventions.

What's in a name? Inflammatory airway disease in racehorses in training

The term 'inflammatory airway disease' (IAD) is often used to describe the syndrome of lower airway inflammation that frequently affects young racehorses in training around the world. In practice, this inflammation is generally diagnosed using a combination of endoscopic tracheal examination, including grading of amounts of mucus present and tracheal wash sampling. However, a recent consensus statement from the American College of Veterinary Internal Medicine concluded that bronchoalveolar lavage (BAL) sampling, rather than tracheal wash (TW) sampling, is required for cytological diagnosis of IAD and that tracheal mucus is not an essential criterion. However, as BAL is a relatively invasive procedure that is not commonly used on racing yards, this definition can only be applied routinely to a biased referral population. In contrast, many practitioners continue to diagnose IAD using endoscopic tracheal examination and sampling. We argue that, rather than restricting the use of the term IAD to phenotypes diagnosed by BAL, it is important to distinguish in the literature between airway inflammation diagnosed by BAL and that identified in the field using TW sampling. We suggest the use of the term brIAD for the former and trIAD for the latter. It is essential that we continue to endeavour to improve our understanding of the aetiology, pathogenesis and clinical relevance of airway inflammation identified in racehorses in training using tracheal examination and sampling. Future studies should focus on investigations of the component signs of airway inflammation.

Social Network Analysis and Qualitative Comparative Analysis: Their mutual benefit for the explanation of policy network structures

By switching the level of analysis and aggregating data from the micro-level of individual cases to the macro-level, quantitative data can be analysed within a more case-based approach. This paper presents such an approach in two steps: In a first step, it discusses the combination of Social Network Analysis (SNA) and Qualitative Comparative Analysis (QCA) in a sequential mixed-methods research design. In such a design, quantitative social network data on individual cases and their relations at the micro-level are used to describe the structure of the network that these cases constitute at the macro-level. Different network structures can then be compared by QCA. This strategy allows adding an element of potential causal explanation to SNA, while SNA-indicators allow for a systematic description of the cases to be compared by QCA. Because mixing methods can be a promising, but also a risky endeavour, the methodological part also discusses the possibility that underlying assumptions of both methods could clash. In a second step, the research design presented beforehand is applied to an empirical study of policy network structures in Swiss politics. Through a comparison of 11 policy networks, causal paths that lead to a conflictual or consensual policy network structure are identified and discussed. The analysis reveals that different theoretical factors matter and that multiple conjunctural causation is at work. Based on both the methodological discussion and the empirical application, it appears that a combination of SNA and QCA can represent a helpful methodological design for social science research and a possibility of using quantitative data with a more case-based approach.
