Stenchaetothrips indicus

description: Stenchaetothrips indicus (Ramakrishna & Margabandhu)
 Female macroptera. Body and legs clear yellow, abdominal segments VIII–X slightly darker (Fig. 4); antennal segments I–V pale, V slightly shaded at extreme apex, VI light brown on distal third, VII light brown; fore wing pale. Head evenly convex in front (Fig. 2); ocellar setae II long, but not twice as long as ocellar setae III; all post-ocellar setae long and subequal in length. Pronotum with more than 50 discal setae, widely spaced transverse striations at anterior and median area, and closely spaced striations near posterior margin; with 2 pairs of long, slender posteroangular setae, 5 pairs of short postero-marginal setae (Fig. 2). Mesonotum with no anterior campaniform sensilla. Metanotum with closely spaced striations, campaniform sensilla absent, median setae arising far behind anterior margin. Meso- and metafurca each without a spinula; metasternum with about 30 discal setae. Abdominal tergites VI–VIII with paired ctenidia, V with a very weak pair; tergite I with a few striations across segment, II–VII without transverse striations medially; tergites II–VIII posterior margin simple, without microtrichia; submedian discal setae on VIII unusually long, extending beyond posterior margin (Fig. 6); IX without anterior pair of campaniform sensilla (Fig. 6). Sternites with no marginal microtrichia.
 Specimens studied. MALAYSIA, Terengganu, Kuala Ibai, 5 females on Cymbopogen citratus, 9.xii.2011 (Ng, Y.F.) (CISUKM; ANIC).
 Comments. The females identified here as S. indicus differ from those seen from Australia (Mound 2011) in having the submedian discal setae on tergite VIII very long, extending beyond the posterior margin of the tergite. Similar specimens have been studied from Thailand and from Papua New Guinea, but the Australian specimens have this pair of setae not extending beyond the posterior margin of the segment. The specimens from Malaysia have numerous pronotal discal setae, but the number of these setae is considered to be variable in S. indicus (Mound 2011). One of these females has a complete row of setae on the first vein of one fore wing, although the other wing has the normal chaetotaxy of 3 or 4 setae on the distal half.

description: This work presents an overview of the spatial resolution criteria in classical optics, digital optics and holography. Although the classical Abbe and Rayleigh resolution criteria have been thoroughly discussed in the literature, there are still several issues which still need to be addressed, for example the axial resolution criterion for coherent and incoherent radiation, which is a crucial parameter of three-dimensional (3D) imaging, the resolution criteria in the Fresnel regime, and the lateral and axial resolution criteria in digital optics and holography. This work discusses these issues and provides a simple guide for which resolution criteria should be applied in each particular imaging scheme: coherent/incoherent, far- and near-field, lateral and axial resolution. Different resolution criteria such as two-point resolution and the resolution obtained from the image spectrum (diffraction pattern) are compared and demonstrated with simulated examples. Resolution criteria for spatial lateral and axial resolution are derived, and their application in imaging with coherent and incoherent (noncoherent) waves is considered. It is shown that for coherent light, the classical Abbe and Rayleigh resolution criteria do not provide an accurate estimation of the lateral and axial resolution. Lateral and axial resolution criteria based on an evaluation of the spectrum of the diffracted wave provide a more precise estimation of the resolution for coherent and incoherent light. It is also shown that resolution criteria derived in approximation of the far-field imaging regime can be applied for the near-field (Fresnel) regime.

description: Damage to trees and logs during harvest and transport can result in major losses of wood volume and value. The study compared a harvester/forwarder (two-machine) harvest system, which typically is used in Australia, with a feller-buncher/processor/forwarder (three-machine) harvest system in terms of productivity, cost and felling stem breakage when clearfelling a 29-year-old Pinus radiata plantation in eastern Victoria, Australia. The study aimed to determine whether the three-machine harvest system reduced felling tree breakage while maintaining or improving on the productivity and delivered cost of the two-machine harvest system. The harvest systems were compared on adjacent sites (~1 ha each) using an elemental time study. Machine productivity was derived from cycle times using StanForD stem files to obtain merchantable tree volumes and forwarder load weights from the forwarder’s onboard scales. The three-machine harvest system was more productive and resulted in considerably less felling stem breakage than the two-machine harvest system (two broken stems compared with 21 broken stems). However, it was approximately 41% more expensive than the two-machine harvest system in terms of cost per m3 of logs delivered to roadside. Because chiplogs were cut from broken stem sections where possible, and it was unlikely that sawlog volume was lost through stem breakage (based on the minimum sawlog specifications and the length and large-end diameter of the broken stem sections), any financial losses resulting from the additional breakage in the two-machine harvest system were insignificant compared with the extra cost per m3 of logs delivered for the three-machine harvest system.

description: This paper evaluates the effects of the lack of regulatory commitment on emission tax applied by the regulator, abatement effort made by the monopoly and social welfare comparing two alternative policy games. The first game assumes that the regulator commits to an ex-ante level of the emission tax. In the second one, in a first stage the regulator and the monopolist simultaneously choose the emission tax and abatement respectively, and in a second stage the monopolist selects the output level. We find that the lack of commitment leads to lower taxation and abatement that yield larger emissions and, consequently, a larger steady-state pollution stock. Moreover, the increase of environmental damages because of the increase in the pollution stock more than compensates the increase in consumer surplus and the decrease in abatement costs resulting in a reduction of social welfare. Thus, our analysis indicates that the lack of commitment has a negative impact of welfare although this detrimental effect decreases with abatement costs.

description: In this paper, we consider spaces whose Higson coronae are indecomposable continua. We show that for a non-compact proper metric space $X$ which is coarsely geodesic and has coarse bounded geometry, the Higson corona of $X$ is an indecomposable continuum if and only if $X$ is coarsely equivalent to the space of natural numbers. Then we give characterizations of finitely generated groups that have one or two ends by decomposability/indecomposability of the components of their Higson coronae. we characterize it as a group whose Higson corona is a topological sum of two indecomposable continua.

description: This paper is devoted to the investigation of the radiation energy losses of an ultra-relativistic charged particle channeling along a crystal plane which is periodically bent by a transverse acoustic wave. In such a system there are two essential mechanisms leading to the photon emission. The first one is the ordinary channeling radiation. This radiation is generated as a result of the transverse oscillatory motion of the particle in the channel. The second one is the acoustically induced radiation. This radiation is emitted because of the periodic bending of the particle's trajectory created by the acoustic wave. The general formalism described in our work is applicable for the calculation of the total radiative losses accounting for the contributions of both radiation mechanisms. We analyze the relative importance of the two mechanisms at various amplitudes and lengths of the acoustic wave and the energy of the projectile particle. We establish the ranges of projectile particle energies, in which total energy loss is small for the LiH, C, Si, Ge, Fe and W crystals. This result is important for the determination of the projectile particle energy region, in which acoustically induced radiation of the undulator type and also the stimulated photon emission can be effectively generated. The latter effects have been described in our previous works.

Мы наблюдаем взаимосвязь вопросов, относящихся к трем концепциям, и то, как они переплетаются в геополитической реальности. Несмотря на онтологическую иерархию трех концепций, в которой национальная безопасность находится на самом высоком уровне обобщения, а энергетическая дипломатия — на самом низком, они постоянно встречаются и пересекаются в реальной политике в динамичных отношениях. В статье конкретно рассматривается интеграция энергетической дипломатии во внешнюю политику.

description: Pyrrolizidine alkaloids (PAs) and their corresponding N-oxides (PANOs) have been determined in food and feed at levels relevant for consumer health. More than 660 different PAs have been detected, but few are available as reference substances for analytical demands. In the context of the European legislation on maximum levels of PAs in food products, a defined analytical scope of 21 PAs for determination has been suggested. An expansion of the scope from 21 to 35 PAs, including 14 structural isomers, is currently under discussion. In the present study, a target screening method was established for a comprehensive characterisation of PA profiles of the species Echium vulgare, Heliotropium europaeum, Cynoglossum officinale and Symphytum spp. to assess whether an expansion of the analytical scope is required to quantitatively cover the total PA contents of Boraginaceae species. The scope of the method comprised known and unknown PAs previously screened and confirmed in the respective plant extracts. A total of 176 PAs and PANOs were detected. The toxic 1,2-unsaturated PAs represent the predominant PA type with about 98% of the mean total content. This PA profiling demonstrates that an expansion of the scope from 21 to 35 PAs is required to adequately cover the mean total PA contents of Cynoglossum officinale and H. europaeum, whereas in the case of Symphytum spp. and Echium vulgare an expansion would not be necessary.

description: In this paper we first analyzed the inductive bias underlying the data scattered across complex free energy landscapes (FEL), and exploited it to train deep neural networks which yield reduced and clustered representation for the FEL. Our parametric method, called Information Distilling of Metastability (IDM), is end-to-end differentiable thus scalable to ultra-large dataset. IDM is also a clustering algorithm and is able to cluster the samples in the meantime of reducing the dimensions. Besides, as an unsupervised learning method, IDM differs from many existing dimensionality reduction and clustering methods in that it neither requires a cherry-picked distance metric nor the ground-true number of clusters, and that it can be used to unroll and zoom-in the hierarchical FEL with respect to different timescales. Through multiple experiments, we show that IDM can achieve physically meaningful representations which partition the FEL into well-defined metastable states hence are amenable for downstream tasks such as mechanism analysis and kinetic modeling.

description: AgBalance comprises a multi-criteria life cycle based approach in combination with a defined aggregation and summary of single results into a single sustainability score (Frank et al. 2012). AgBalanceTM delivers results that enable farmers, the food industry, politicians and society to objectively evaluate processes in terms of their sustainability profile. In doing so, a vast amount of information on individual factors can be ascertained in addition to overall statements on the sustainability of agricultural practices (e. g. ploughing). AgBalance was finalized in mid of 2011. In September 2011, the methodology was given independent assurance by the global expert agencies such as DNV Business Assurance. AgBalanceTM can be used to map an individual farm or the whole agricultural sector in one region, for example. The focus can either be on the agricultural production system alone or on the processes that have established themselves downstream in the value chain, such as logistics or processing. Measuring sustainability can be a central key to steady improvements towards sustainable agriculture. It is therefore an essential requirement that it succeeds in translating results from complicated life-cycle analyses into farmers’ everyday reality and to derive specific recommendations for action from this. Novel IT solutions are required in order to make use of LCA-based knowledge for a more sustainable crop management on-farm. This is the basic idea of the online game “AgBalance – My Virtual Farm”.

description: The rate constants for the formation, destruction, and collisional excitation of SH$^+$ are calculated from quantum mechanical approaches using two new SH$_2^+$ potential energy surfaces (PESs) of $^4A''$ and $^2A''$ electronic symmetry. The PESs were developed to describe all adiabatic states correlating to the SH$^+$ ($^3Σ^-$) + H($^2S$) channel. The formation of SH$^+$ through the S$^+$ + H$_2$ reaction is endothermic by $\approx$ 9860 K, and requires at least two vibrational quanta on the H$_2$ molecule to yield significant reactivity. Quasi-classical calculations of the total formation rate constant for H$_2$($v=2$) are in very good agreement with the quantum results above 100K. Further quasi-classical calculations are then performed for $v=3$, 4, and 5 to cover all vibrationally excited H$_2$ levels significantly populated in dense photodissociation regions (PDR). The new calculated formation and destruction rate constants are two to six times larger than the previous ones and have been introduced in the Meudon PDR code to simulate the physical and illuminating conditions in the Orion bar prototypical PDR. New astrochemical models based on the new molecular data produce four times larger SH$^+$ column densities, in agreement with those inferred from recent ALMA observations of the Orion bar.

title: Relationship between α-synuclein aggregate accumulation and aquaporin-4 expression in multiple system atrophy and Dementia with Lewy Bodies

Subjects: subject: glymphatic system

description: Multiple system atrophy (MSA) and Dementia with Lewy Bodies (DLB) are atypical Parkinsonian disorders or synucleinopathies characterised by accumulation of alphasynuclein (α-synuclein) protein deposits in the form of Lewy bodies (LB), Lewy neurites (LN) and glial cytoplasmic inclusions (GCI). Accumulation of these protein aggregates are responsible for the loss of dopaminergic neurons in the substantia nigra (SN) and subsequent motor deficits and non-motor symptomology, such as dementia in the case of DLB. Mounting evidence suggests that protein aggregates can alter the perivascular expression of astrocytic aquaporin-4 (AQP4), thus disrupting glymphatic flow and waste clearance. The glymphatic system is a brain-wide network of perivascular channels that preserves brain homeostasis by facilitating fluid exchange and clearance of cellular waste. The perivascular expression of astrocytic AQP4 has been identified as a key component of the glymphatic network, functioning as a water-selective transporter that regulates glymphatic flow. Efficient glymphatic flow ensures the timely removal of neurotoxic substances such as a-synuclein from the brain's interstitial space. If the glymphatic system is compromised, as may occur with impaired expression of aquaporin-4, the clearance of α-synuclein is impeded. The accumulation of α-synuclein aggregates triggers an inflammatory response, further exacerbating neuronal damage. Consequently, impaired waste clearance not only allows for the build-up of detrimental protein aggregates but also fosters a neuroinflammatory environment, both of which are implicated in the progression of MSA and DLB. Understanding and addressing the role of glymphatic flow in clearing α-synuclein may provide insights into potential therapeutic strategies for mitigating the impact of Parkinson's and related neurodegenerative disorders.

description: Phytochemical investigation of the water extract from the leaves of Perilla frutescens (Lamiaceae) led to the isolation of a new flavanone, a new chalcone, and a new aurone, namely, (2S)-5,7-dimethoxy-8,4'-dihydroxyflavanone (1), 2',4'-dimethoxy-4,5',6'-trihydroxychalcone (2), and (Z)-4,6-dimethoxy-7,4'-dihydroxyaurone (3), respectively. The structures were unambiguously elucidated on the basis of spectroscopic data. And the absolute configuration of 1 was determined by analysis of electronic circular dichroism spectrum. The isolated compounds were evaluated for their inhibitory effects on xanthine oxidase in vitro. Among them, 2 showed more potent activity than the positive control allopurinol, a well-known XO inhibitor clinically used for treatment of gout. Lineweaver-Burk transformation of the inhibition kinetics data demonstrated that it was a mixed-type inhibitor.

description: We have carried out an analysis of the radio and optical properties of a statistical sample of 45 Seyfert galaxies from the Palomar spectroscopic survey of nearby galaxies. We find that the space density of bright galaxies (-22 mag <= M_{B_T} <= -18 mag) showing Seyfert activity is (1.25 +/- 0.38) X 10^{-3} Mpc^{-3}, considerably higher than found in other Seyfert samples. Host galaxy types, radio spectra, and radio source sizes are uncorrelated with Seyfert type, as predicted by the unified schemes for active galaxies. Approximately half of the detected galaxies have flat or inverted radio spectra, more than expected based on previous samples. Surprisingly, Seyfert 1 galaxies are found to have somewhat stronger radio sources than Seyfert 2 galaxies at 6 and 20 cm, particularly among the galaxies with the weakest nuclear activity. We suggest that this difference can be accommodated in the unified schemes if a minimum level of Seyfert activity is required for a radio source to emerge from the vicinity of the active nucleus. Below this level, Seyfert radio sources might be suppressed by free-free absorption associated with the nuclear torus or a compact narrow-line region, thus accounting for both the weakness of the radio emission and the preponderance of flat spectra. Alternatively, the flat spectra and weak radio sources might indicate that the weak active nuclei are fed by advection-dominated accretion disks.

description: A liquid chromatography-high resolution mass spectrometry (LC-HRMS) method was developed and validated for the determination of residual peptide antibiotics (bacitracin A, colistin A and B, enramycin A and B, virginiamycin M1 and S1) in bovine milk. LC-HRMS accurate mass data provided the necessary selectivity and sensitivity to quantitate and identify these important antibiotics in milk at residue levels without extensive sample preparation. Milk samples were extracted using 0.3% formic acid in acetonitrile with 0.06% trifluoroacetic acid added to improve peptide recoveries. Sample clean-up was minimal with an aliquot of the extract evaporated and reconstituted in a formic acid/water-acetonitrile mixture and then filtered. LC separation was performed with 0.3% formic acid in the gradient to improve the peak shape and reproducibility of the peptide analytes. A Quadruple-Orbitrap HRMS instrument with full-scan MS1 data collection followed by all-ion-fragmentation was used to obtain the exact mass of the precursor and confirmatory product ions. One advantage of LC-HRMS is that a combination of multiple precursor ions, including different charge states or adducts, can be used for quantification. The method was validated at four concentration levels ranging from 12.5 to 200 ng/g in three types of bovine milk. For bacitracin A, colistins and enramycins, the average recoveries compared to solvent standards ranged between 70% and 120%. Average recoveries for virginiamycin residues in milk extracts were unacceptably high (up to 138%) using solvent standards, but recoveries using matrix-matched calibration were determined to be 90–115%. Matrix effects were found to be less than 25% for the other analytes when internal standard correction was used for the colistins. Intra-day relative standard deviations were generally below 15%. The method detection limits for the peptide antibiotic residues in milk (0.5 to 5.5 ng/g) were well below regulatory levels of concern.

description: We present a quantum theory of dielectric energy loss arising from the piezoelectric coupling between photons and phonons in superconducting devices. Photon loss is shown to occur predominantly at the interface, where the piezoelectric effect is non-zero even when the materials are perfectly crystalline (epitaxial) and free of two-level system defects. We present explicit numerical calculations for the value of the intrinsic loss tangent at several interfaces to conclude that the $T_1$ of superconducting qubits may reach $10^{4}$ $μ$s if the device is made with defect-free interfaces.

description: We present a stereo-based dense mapping algorithm for large-scale dynamic urban environments. In contrast to other existing methods, we simultaneously reconstruct the static background, the moving objects, and the potentially moving but currently stationary objects separately, which is desirable for high-level mobile robotic tasks such as path planning in crowded environments. We use both instance-aware semantic segmentation and sparse scene flow to classify objects as either background, moving, or potentially moving, thereby ensuring that the system is able to model objects with the potential to transition from static to dynamic, such as parked cars. Given camera poses estimated from visual odometry, both the background and the (potentially) moving objects are reconstructed separately by fusing the depth maps computed from the stereo input. In addition to visual odometry, sparse scene flow is also used to estimate the 3D motions of the detected moving objects, in order to reconstruct them accurately. A map pruning technique is further developed to improve reconstruction accuracy and reduce memory consumption, leading to increased scalability. We evaluate our system thoroughly on the well-known KITTI dataset. Our system is capable of running on a PC at approximately 2.5Hz, with the primary bottleneck being the instance-aware semantic segmentation, which is a limitation we hope to address in future work. The source code is available from the project website (http://andreibarsan.github.io/dynslam).

description: We discuss the proof of and systematic application of Case's sum rules for Jacobi matrices. Of special interest is a linear combination of two of his sum rules which has strictly positive terms. Among our results are a complete classification of the spectral measures of all Jacobi matrices J for which J-J_0 is Hilbert--Schmidt, and a proof of Nevai's conjecture that the Szego condition holds if J-J_0 is trace class.

title: The relationship between psychological contract (PC) breach and employees' behavioural responses: the role of PC violation, PC type and work as calling
Creators: name: Jamil, Aditi
Publisher: name: Griffith University

Subjects: subject: psychological contract
subject: vocation
subject: employee behaviour

description: The changing nature of work and the growing emphasis on finding purpose have made it crucial to understand how an employee's sense of purpose affects their behaviour when dissatisfied with their relationship with their employer. Additionally, the COVID-19 pandemic has brought about significant changes in work conditions and expectations between employees and employers, leading to precarious work conditions and alterations in the psychological contract (PC) that employees have with their organisations. This research addresses this important issue by exploring how employees respond behaviourally to organisational actions, employing both the psychological contract (PC) theory and the Exit-Voice-Loyalty-Neglect (EVLN) framework. Furthermore, the study investigates how an employee's perception of work as a calling (WAC) impacts their overall assessment, emotional response, and subsequent behavioural reaction when the organisation fails to meet its commitments. Through the proposal of a theoretical model and the empirical testing of a set of hypotheses, this research expands the application of PC theory and the EVLN framework by introducing WAC as a moderator in the relationship between PC breach, PC violation, and EVLN behaviours.

description: Mayonnaise is the most consumed condiment in the U.S. with domestic consumers spending some $2 billion on its consumption and with a couple of brands controlling a significant portion of the market. However, the demand for mayonnaise at the brand level has not been studied extensively in previous research. In this study, the Barten synthetic model was estimated to investigate the demand for mayonnaise and competition among major mayonnaise brands (private label, Hellmann’s, Kraft, and other brands) in Northeast Texas. Compensated cross-price elasticities revealed that Kraft was the major competitor to private label and other brands, while private label was the major competitor to Kraft.

description: We investigate the growth optimal strategy over a finite time horizon for a stock and bond portfolio in an analytically solvable multiplicative Markovian market model. We show that the optimal strategy consists in holding the amount of capital invested in stocks within an interval around an ideal optimal investment. The size of the holding interval is determined by the intensity of the transaction costs and the time horizon.

description: Selective androgen receptor modulators (SARMs) are a class of new emerging “designer” steroid compounds gaining popularity over more well established anabolic-androgenic steroids (AAS) amongst both non-professional and elite athletes. Moreover, due to their anabolic activity, SARM compounds may also potentially be abused in livestock animals to increase meat production. Consequently, SARM residues should be monitored as a part of routine testing employed within both anti-doping and drug residue laboratories. Since only a limited amount of information on SARM compound stability is currently available within the peer-reviewed literature, this study reports a practical approach to assess optimal storage conditions for 15 SARM compounds in solvent solutions (standard stock and intermediate mixed standard solutions) stored at −20°C for up to 1 year, as well as in a range of urine test matrices (bovine, equine, canine and human) under frozen (−20°C, −80°C) storage for up to 20 weeks and post freeze-thaw cycles. Moreover, SARM storage stability within solvent extracts was assessed at −20°C (0–4 weeks) and 4°C (0–2 weeks). Findings demonstrate that SARM analytes are stable in reference solutions when stored at −20°C, apart from PF-06260414 (stock solution) which should be stored at lower temperatures (e.g. −80°C). A limited degree of compound instability was observed for a number of SARM analytes in urine both when stored at −20°C, and after repeated freeze-thaw cycles. Moreover, SARM compounds within reconstituted urine solvent extracts were found to be effectively stable when stored for up to 4 weeks at −20°C and for 2 weeks at 4°C. The long-term stability testing data reported here will inform the more timely and effective development and validation of analytical methods for SARM residue detection and analysis, ensuring confidence in findings from monitoring of livestock animals and anti-doping processes.
Locally optimal routes for route choice sets

description: Route choice is often modelled as a two-step procedure in which travellers choose their routes from small sets of promising candidates. Many methods developed to identify such choice sets rely on assumptions about the mechanisms behind the route choice and require corresponding data sets. Furthermore, existing approaches often involve considerable complexity or perform many repeated shortest path queries. This makes it difficult to apply these methods in comprehensive models with numerous origin-destination pairs. In this paper, we address these issues by developing an algorithm that efficiently identifies locally optimal routes. Such paths arise from travellers acting rationally on local scales, whereas unknown factors may affect the routes on larger scales. Though methods identifying locally optimal routes are available already, these algorithms rely on approximations and return only few, heuristically chosen paths for specific origin-destination pairs. This conflicts with the demands of route choice models, where an exhaustive search for many origins and destinations would be necessary. We therefore extend existing algorithms to return (almost) all admissible paths between a large number of origin-destination pairs. We test our algorithm on a road network modelling the Canadian province British Columbia and analyze the distribution of locally optimal paths in the province.

description: We discuss the radiation generated by positrons channeling in a crystalline undulator. The undulator is produced by periodically bending a single crystal with an amplitude much larger than the interplanar spacing. Different approaches for bending the crystal are described and the restrictions on the parameters of the bending are discussed. We also present numeric calculations of the spontaneous emitted radiation and estimate the conditions for stimulated emission. Our investigations show that the proposed mechanism could be an interesting source for high energy photons and is worth to be studied experimentally.

description: The FDA received petitions to more clearly define the content of the natural label or even prohibit its use. Against this background, we conducted an online choice experiment to determine consumer preferences for boneless USDA Choice ribeye steaks. We also determined if providing consumers with information regarding the legal definition of natural had an impact on consumer preferences. Results indicate that natural labeling has a positive impact on consumer utility when consumers were not aware of the definition of natural; this impact was not found when consumers were informed of the definition of natural.

description: This paper analyzes a series of policies and programs for the comprehensive rural development of Korea, and proposes a suitable method for rural development in developing countries. Each policy is described and compared based on the background, implementation methods, progress, performance, implications, etc. This study provides suggestions for developing countries with useful practical tips on eradicating absolute poverty, including appropriate target regions and comprehensive development strategies adoption. This paper provides several policies and project support for rural development in developing countries. However, Korea's successful experience will not produce the same effects on developing countries. Therefore, those suggestions need to be adopted with considerations on specific social, economic contexts of developing countries.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
