Teaching in the garden: school gardens as a space for environmental and English learning

School gardens as settings for learning outside the classroom are becoming increasingly popular. They allow students to learn in an authentic way as they engage in a variety of activities and materials. More importantly, they also represent a powerful place and tool for environmental education as students are not only exposed to nature but also gain positive environmental experiences. This paper examines school gardens as a place for both enhancing students’ English language competences and fostering critical environmental literacy. The first section of the paper focuses on garden-based education as a type of learning outside the classroom. The ensuing section then provides a brief discussion of school gardens as learning spaces across the curriculum, arguing that school gardens are far more than places for learning about nutrition and healthy living. Following this, the next section then argues for using school gardens also for learning English as a foreign language. Here Gardner’s multiple intelligences model serves to illustrate the potential of school gardens for differentiated instruction regarding content, processes, and products in today’s increasingly diverse learning groups. The main part of the paper then concentrates on garden-based education in the context of EFL teacher training. At the University of Education Karlsruhe (Germany) students have the opportunity to attend a school garden-based seminar which allows them to experience first hand the benefits of learning English as a foreign language in the school garden. The paper concludes by taking a glimpse into the future of school garden learning by reporting on the authors’ experiences with using technology in the context of garden-based education.Los huertos escolares como escenario para el aprendizaje fuera del aula son cada vez más populares. Permiten que los estudiantes aprendan de una manera auténtica mientras participan en actividades que implican una variedad de actividades y materiales. De forma más relevante, estos también representan un lugar y una herramienta poderosa para la educación ambiental, ya que los estudiantes no sólo están expuestos a la naturaleza, sino que también recogen experiencias en la naturaleza, lo que les permite obtener experiencias ambientales positivas. En este documento se examinan los huertos escolares como un lugar para mejorar las competencias de los estudiantes en el idioma inglés y fomentar una alfabetización ambiental crítica. La primera sección del documento se centra en la educación basada en los jardines como un tipo de aprendizaje fuera del aula. A continuación, se ofrece un breve análisis de los huertos escolares como espacios de aprendizaje en todo el programa de estudios, argumentando que los huertos escolares son mucho más que lugares para aprender sobre nutrición y vida saludable. A continuación, en la siguiente sección se argumenta que los huertos escolares también sirven para aprender inglés como lengua extranjera. Aquí el modelo de inteligencias múltiples de Gardner sirve para ilustrar el potencial de los huertos escolares para la instrucción diferenciada en cuanto a contenido, procesos y productos en los grupos de aprendizaje cada vez más diversos de hoy en día. La parte principal del trabajo se centra entonces en la educación basada en los huertos en el contexto de la formación de profesores de EFL. En la Universidad de Educación de Karlsruhe (Alemania), los estudiantes tienen la oportunidad de asistir a un seminario sobre huertos escolares que les permite experimentar de primera mano las ventajas de aprender inglés como lengua extranjera en este espacio. La contribución concluye echando un vistazo al futuro del aprendizaje en los huertos escolares, informando sobre las experiencias de los autores en el uso de la tecnología en el contexto de la educación basada en los huertos

Seasonal variation of upwelling in the Alaskan Beaufort Sea : impact of sea ice cover

The definitive version was published in Journal of Geophysical Research 117 (2012): C06022, doi:10.1029/2012JC007985.Data from a mooring array deployed from August 2002 to September 2004 are used to characterize differences in upwelling near the shelf break in the Alaskan Beaufort Sea due to varying sea ice conditions. The record is divided into three ice seasons: open water, partial ice, and full ice. The basic response is the same in each of the seasons. Roughly 8 h after the onset of easterly winds the shelf break jet reverses, followed approximately 10 h later by upwelling of saltier water which is cold near the shelf break (Pacific Winter Water) and warm at depth (Atlantic Water). The secondary circulation at the outer shelf is, to first order, consistent with a two-dimensional Ekman balance of offshore flow in the upper layer and onshore flow at depth. There are, however, important seasonal differences in the upwelling. Overall the response is strongest in the partial ice season and weakest in the full ice season. It is believed that these differences are dictated by the degree to which wind stress is transmitted through the pack-ice, as the strength of the wind-forcing was comparable over the three seasons. An EOF-based upwelling index is constructed using information about the primary flow, secondary flow, and hydrography. The ability to predict upwelling using the wind record alone is explored, which demonstrates that 90% of easterly wind events exceeding 9.5 m s−1 drive significant upwelling. During certain periods the ice cover on the shelf became landfast, which altered the upwelling and circulation patterns near the shelf break.The following grants provided support for this study: National Ocean Partnership Program project N00014-07-1-1040 and National Science Foundation projects OPP-0731928 and OPP-0713250.2012-12-2

Somatostatin secretion by Na+-dependent Ca2+-induced Ca2+ release in pancreatic delta-cells.

Pancreatic islets are complex micro-organs consisting of at least three different cell types: glucagon-secreting α-, insulin-producing β- and somatostatin-releasing δ-cells1. Somatostatin is a powerful paracrine inhibitor of insulin and glucagon secretion2. In diabetes, increased somatostatinergic signalling leads to defective counter-regulatory glucagon secretion3. This increases the risk of severe hypoglycaemia, a dangerous complication of insulin therapy4. The regulation of somatostatin secretion involves both intrinsic and paracrine mechanisms5 but their relative contributions and whether they interact remains unclear. Here we show that dapagliflozin-sensitive glucose- and insulin-dependent sodium uptake stimulates somatostatin secretion by elevating the cytoplasmic Na+ concentration ([Na+]i) and promoting intracellular Ca2+-induced Ca2+ release (CICR). This mechanism also becomes activated when [Na+]i is elevated following the inhibition of the plasmalemmal Na+-K+ pump by reductions of the extracellular K+ concentration emulating those produced by exogenous insulin in vivo6. Islets from some donors with type-2 diabetes hypersecrete somatostatin, leading to suppression of glucagon secretion that can be alleviated by a somatostatin receptor antagonist. Our data highlight the role of Na+ as an intracellular second messenger, illustrate the significance of the intraislet paracrine network and provide a mechanistic framework for pharmacological correction of the hormone secretion defects associated with diabetes that selectively target the δ-cells

The three dimensions of online child pornography offending

The internet has opened up opportunities for non-contact sex offending, such as the viewing of child pornography. This paper proposes a model for the classification of child pornography offenders as an aid for their assessment and treatment, deducted from empirical studies and existing typologies for child pornography offenders. Different subgroups of child pornography offenders may be described according to three dimensions: (1) type of offending, (2) the motivation behind child pornography offending and (3) the situational and social engagement in the offending behaviour. Distinct pathways of child pornography offending can be identified, related to differing criminogenic needs, severity of offending, and appropriate assessment and treatment strategies for the offenders

Ambulatory assessment for physical activity research. State of the science, best practices and future directions

Technological and digital progress benefits physical activity (PA) research. Here we compiled expert knowledge on how Ambulatory Assessment (AA) is utilized to advance PA research, i.e., we present results of the 2nd International CAPA Workshop 2019 "Physical Activity Assessment - State of the Science, Best Practices, Future Directions" where invited researchers with experience in PA assessment, evaluation, technology and application participated. First, we provide readers with the state of the AA science, then we give best practice recommendations on how to measure PA via AA and shed light on methodological frontiers, and we furthermore discuss future directions. AA encompasses a class of methods that allows the study of PA and its behavioral, biological and physiological correlates as they unfold in everyday life. AA includes monitoring of movement (e.g., via accelerometry), physiological function (e.g., via mobile electrocardiogram), contextual information (e.g., via geolocation-tracking), and ecological momentary assessment (EMA; e.g., electronic diaries) to capture self-reported information. The strengths of AA are data assessment that near real-time, which minimizes retrospective biases in real-world settings, consequentially enabling ecological valid findings. Importantly, AA enables multiple assessments across time within subjects resulting in intensive longitudinal data (ILD), which allows unraveling within-person determinants of PA in everyday life. In this paper, we show how AA methods such as triggered e-diaries and geolocation-tracking can be used to measure PA and its correlates, and furthermore how these findings may translate into real-life interventions. In sum, AA provides numerous possibilities for PA research, especially the opportunity to tackle within-subject antecedents, concomitants, and consequences of PA as they unfold in everyday life. In-depth insights on determinants of PA could help us design and deliver impactful interventions in real-world contexts, thus enabling us to solve critical health issues in the 21st century such as insufficient PA and high levels of sedentary behavior.

CA 15-3 is predictive of response and disease recurrence following treatment in locally advanced breast cancer

BACKGROUND: Primary chemotherapy (PC) is used for down-staging locally advanced breast cancer (LABC). CA 15-3 measures the protein product of the MUC1 gene and is the most widely used serum marker in breast cancer. METHODS: We retrospectively investigated the role of CA 15-3 in conjunction with other clinico-pathological variables as a predictor of response and time to disease recurrence following treatment in LABC. Pre and post primary chemotherapy serum concentrations of CA 15-3 together with other variables were reviewed and related to four outcomes following primary chemotherapy (clinical response, pathological response, time to recurrence and time to progression). Persistently elevated CA 15-3 after PC was considered as consecutively high levels above the cut off point during and after PC. RESULTS: 73 patients were included in this study. Patients received PC (AC or AC-T regimen) for locally advanced breast cancer. 54 patients underwent surgery. The median follow up was 790 days. Patients with high concentrations of CA 15-3 before PC treatment had a poor clinical (p = 0.013) and pathological (p = 0.044) response. Together with Her-2/neu expression (p = 0.009) and tumour lympho-vascular space invasion (LVI) (p = 0.001), a persistently elevated CA 15-3 post PC (p = 0.007) was an independent predictive factor of recurrence following treatment in LABC. CONCLUSION: Elevated CA 15-3 level is predictive of a poor response to chemotherapy. In addition, persistently elevated CA 15-3 levels post chemotherapy in conjunction with lympho-vascular invasion and HER2 status predict a reduced disease free survival following treatment in locally advanced breast cancer

Hidden chromosomal abnormalities in pleuropulmonary blastomas identified by multiplex FISH

BACKGROUND: Pleuropulmonary blastoma (PPB) is a rare childhood dysontogenetic intrathoracic neoplasm associated with an unfavourable clinical behaviour. CASES PRESENTATION: We report pathological and cytogenetic findings in two cases of PPB at initial diagnosis and recurrence. Both tumors were classified as type III pneumoblastoma and histological findings were similar at diagnosis and relapse. In both cases, conventional cytogenetic techniques revealed complex numerical and structural chromosomal abnormalities. Molecular cytogenetic analysis (interphase/metaphase FISH and multicolor FISH) identified accurately chromosomal aberrations. In one case, TP53 gene deletion was detected on metaphase FISH. To date, only few cytogenetic data have been published about PPB. CONCLUSION: The PPB genetic profile remains to be established and compared to others embryonal neoplasia. Our cytogenetic data are discussed reviewing cytogenetics PPBs published cases, illustrating the contribution of multicolor FISH in order to identify pathogenetically important recurrent aberrations in PPB

Phantom motor execution as a treatment for phantom limb pain:protocol of an international, double-blind, randomised controlled clinical trial

Introduction Phantom limb pain (PLP) is a chronic condition that can greatly diminish quality of life. Control over the phantom limb and exercise of such control have been hypothesised to reverse maladaptive brain changes correlated to PLP. Preliminary investigations have shown that decoding motor volition using myoelectric pattern recognition, while providing real-time feedback via virtual and augmented reality (VR-AR), facilitates phantom motor execution (PME) and reduces PLP. Here we present the study protocol for an international (seven countries), multicentre (nine clinics), double-blind, randomised controlled clinical trial to assess the effectiveness of PME in alleviating PLP. Methods and analysis Sixty-seven subjects suffering from PLP in upper or lower limbs are randomly assigned to PME or phantom motor imagery (PMI) interventions. Subjects allocated to either treatment receive 15 interventions and are exposed to the same VR-AR environments using the same device. The only difference between interventions is whether phantom movements are actually performed (PME) or just imagined (PMI). Complete evaluations are conducted at baseline and at intervention completion, as well as 1, 3 and 6 months later using an intention-to-treat (ITT) approach. Changes in PLP measured using the Pain Rating Index between the first and last session are the primary measure of efficacy. Secondary outcomes include: frequency, duration, quality of pain, intrusion of pain in activities of daily living and sleep, disability associated to pain, pain self-efficacy, frequency of depressed mood, presence of catastrophising thinking, health-related quality of life and clinically significant change as patient's own impression. Follow-up interviews are conducted up to 6 months after the treatment. Ethics and dissemination The study is performed in agreement with the Declaration of Helsinki and under approval by the governing ethical committees of each participating clinic. The results will be published according to the Consolidated Standards of Reporting Trials guidelines in a peer-reviewed journal
