Mentalizing techniques used by psychodynamic therapists working with children and early adolescents

The aim of this study was to identify, categorize, and develop a conceptual frame of mentalization-based interventions used by experienced child and adolescent psychodynamic therapists. Two experienced therapists selected 14 sessions that represented their work during the first year of treatment. Sessions were transcribed and segmented to identify interactional units for coding. QDA Miner software was used to facilitate data analysis. A systematic qualitative, inductive/deductive approach was followed starting from categories identified in the literature, but also including newly emerging categories and interventions. Seven sessions were double coded to stabilize the coding tree and a "member check" was completed where therapists rated their own transcripts. A total of 24 mentalization-based techniques were identified, including 17 additional techniques. A conceptual framework organizing all observed mentalization-based interventions is proposed. The findings of this study provide a framework for studying techniques that may enhance the capacity to mentalize, and that could be features of therapeutic practice across a range of modalities of psychotherapy

Technological and Implementation Issues in Moodle-Based Digital Badge System

Digital badges, touted as a gamification tool that can potentially influence learner motivation, engagement and participation, are being used increasingly in a variety of educational domains to facilitate and motivate learning. Using a badge system design implemented in the Moodle learning management platform, data was collected from four experiments from 2015 to 2017 to examine the effects of gamification with the use of digital badges on introductory programming students' intrinsic motivation. This paper provides an in-depth examination of seldomly discussed technological and implementation issues we encountered in implementing our Moodle-based badge system, worthy of exploration to support future gamification studies in this area. Our gamified implementation is analyzed according to five main factors primarily adopted from an IT implementation framework: (1) assessment of needs, (2) choice of technology, (3) technological infrastructure, (4) system and environmental factors and (5) evaluation. The findings highlight enabling and challenging factors associated with the technology and badge implementation. Our experience shows that badge systems may be influenced by contextual factors such as cost and scale of implementation. We provide recommendations to guide educational stakeholders, particularly those considering Moodle as their badge implementation platform

Photon-Photon Entanglement with a Single Trapped Atom

An experiment is performed where a single rubidium atom trapped within a high-finesse optical cavity emits two independently triggered entangled photons. The entanglement is mediated by the atom and is characterized both by a Bell inequality violation of S=2.5, as well as full quantum-state tomography, resulting in a fidelity exceeding F=90%. The combination of cavity-QED and trapped atom techniques makes our protocol inherently deterministic - an essential step for the generation of scalable entanglement between the nodes of a distributed quantum network.Comment: 5 pages, 4 figure

Lasiothyris luminosa (Lepidoptera: Tortricidae): a new grapevine pest in northeastern Brazil.

The little-known Neotropical tortricid moth Lasiothyris luminosa (Razowski& Becker) is reported for the first time as a grapevine pest in Northeastern Brazil. A diagnosis based on morphological characters including the genitalia is provided for both sexes, together with a preliminary description of economic damage caused by the larval stage. In addition, we sequenced a partial region of the cytochrome oxidase subunit I gene from specimens from the region, and reconstructed phylogenetic relationships using representative lineages of closely related tortricids as terminals. The larvais endophagous, feeding on the inflorescence from closed buds before flower anthesistoopen flowers and later, inside fruits at different maturation stages, causing them to rot. Preliminary surveys carried out on a few farms indicate that the effective damage may reach circa 10% of table-grape production in the region

Adaptações de metodologia para criação de Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae).

Helicoverpa armigera (Hübner) destaca-se entre os principais lepidópteros desfolhadores de culturas brasileiras nas duas últimas safras. Visando aprimorar as técnicas de criação de H. armigera em laboratório, foi avaliada uma metodologia de criação no Laboratório de Resistência de Plantas a Insetos e Plantas Inseticidas (LARESPI) da FCA/UNESP, Botucatu. Para criação, os adultos identificados quanto ao sexo e separados em casais são mantidos em gaiolas (tubos de PVC, 20 cm de diâmetro e 30 cm de altura). A face superior das gaiolas são vedadas com tecido voil, permitindo aeração e alimentação dos adultos. A face inferior é apoiada em prato de plástico (28 cm de diâmetro) recoberto com papel filtro. Internamente as gaiolas são forradas com papel kraft natural servindo de substrato para oviposição. Sobre o voil é acondicionada uma porção de algodão umedecido em solução de mel a 10%, e outra contendo apenas água. As lagartas são obtidas a partir das posturas colhidas diariamente no papel kraft e no tecido voil. As posturas são transferidas inicialmente para um recipiente plástico transparente de 500 mL, contendo aproximadamente 50g de dieta artificial. A partir do terceiro instar, é feita a transferência individual das lagartas para recipientes de 50 mL, contendo aproximadamente 5g de dieta artificial. Estes recipientes são vedados com tampas, e as lagartas são mantidas em seu interior até formação das pupas. As pupas são coletadas e acondicionadas em recipientes de acrílico transparente (11,5 x 11,5 x 3,5 cm) contendo vermiculita umedecida, permanecendo nesse ambiente até a emergência dos adultos. A criação é mantida sob temperatura de 25ºC, umidade relativa de 70±10% e fotofase de 12h. A iluminação natural é mantida por lâmpadas dos tipos fluorescente ?super luz do dia? (20W) e fluorescente ?plant light? (grolux F 20 W T12), nas prateleiras de criação. Para averiguação de temperatura e umidade relativa do ar utiliza-se o termohigrômetro digital. Para validação da criação descrita realizaram-se diversos experimentos preliminares. A metodologia apresentada possibilita a criação de H. armigera em diferentes escalas, permitindo a realização de ensaios diversos

Rationality of quotients by linear actions of affine groups

Let G be the (special) affine group, semidirect product of SL_n and C^n. In this paper we study the representation theory of G and in particular the question of rationality for V/G where V is a generically free G-representation. We show that the answer to this question is positive if the dimension of V is sufficiently large and V is indecomposable. We have a more precise theorem if V is a two-step extension 0 -> S -> V -> Q -> 0 with S, Q completely reducible.Comment: 18 pages; dedicated to Fabrizio Catanese on the occasion of his 60th birthda

Battle in the New World: \u3ci\u3eHelicoverpa armigera\u3c/i\u3e versus \u3ci\u3eHelicoverpa zea\u3c/i\u3e (Lepidoptera: Noctuidae)

The corn earworm Helicoverpa zea (Boddie) and the old world bollworm Helicoverpa armigera (HuÈbner) (Lepidoptera: Noctuidae) are allopatric species and occur in important agricultural crops. In maize, both species tend to infest the ear. The introduction of H. armigera in Brazil has created a new scenario, where these Helicoverpa species might cohabit and interact with one another, affecting the prevalence of each species in the agroecosystem, integrated pest management, and insect resistance management. In this study, larval occurrence and proportion of these species in maize was assessed in three regions of Brazil during three crop seasons. Interaction between the species was evaluated in interspecific and intraspecific scenarios under laboratory and field conditions. Helicoverpa zea was predominant in Rio Grande do Sul and the Planaltina, DF (central Brazil). In western Bahia, H. zea was predominant in the first collection, but approximately equal in number to H armigera in the second crop season. Both species exhibit high cannibalism/predation rates, and larval size was the primary factor for larval survival in the interaction studies. Larva of H. zea had higher survival when interacting with H. armigera, indicating that H. zea has an advantage in intraguild interactions with H. armigera in maize. Overall, the results from this study indicate that maize might play a role as a source of infestation or a sink of insecticide or Bt protein unselected H. armigera populations, depending on the H. zea:H. armigera intraguild competition and adult movement in the landscape

Formation of delta ferrite in 9 wt.% Cr steel investigated by in-situ X-ray diffraction using synchrotron radiation

In-situ X-ray diffraction (XRD) measurements using high energy synchrotron radiation were performed to monitor in real time the formation of delta ferrite in a martensitic 9 wt pct chromium steel under simulated weld thermal cycles. Volume fractions of martensite, austenite, and delta ferrite were measured as a function of temperature at a 10 K/s heating rate to 1573 K (1300 °C) and subsequent cooling. At the peak temperature, the delta ferrite concentration rose to 19 pct, of which 17 pct transformed back to austenite on subsequent cooling.Max Kade Foundation, Inc.Austrian Academy of SciencesUnited States.
