Late Jurassic (Kimmeridgian–Tithonian) stable isotopes (δ18O, δ13C) and Mg/Ca ratios: New palaeoclimate data from Helmsdale, northeast Scotland
2010
Abstract The data presented here provide the first detailed stable isotope ( δ 18 O, δ 13 C) and geochemical (Mg/Ca) investigation of Kimmeridgian–Tithonian belemnites from the Helmsdale Coast, Scotland, UK. Oxygen and carbon stable isotope values from well preserved specimens range from − 2.8 to + 0.3‰ and from − 2.3 to + 2.8‰ respectively. The oxygen isotope data are consistent with palaeotemperatures of up to 24 °C in the Early Kimmeridgian cymodoce Zone and down to 11 °C in the Mid Tithonian rotunda–fittoni Zones. These estimates are strongly supported by the Mg/Ca data, which also indicate a cooling episode (and very similar palaeotemperatures, 11–22 °C) at this time. The cooling event…
A 2600-year record of past polycyclic aromatic hydrocarbons (PAHs) deposition at Holzmaar (Eifel, Germany)
2014
Polycyclic aromatic hydrocarbons (PAHs) are a proxy for climate- and human-related historical fire activity which has rarely been used beyond 1800 AD. We explored the concentration and composition patterns of PAHs together with other proxies (charcoal, C, N, S, δ13C, δ15N, and δ34S) in a sediment core of Holzmaar as indicators of variations in climate and anthropogenic activity over the past 2600 years. The concentrations of pyrogenic PAHs remained low (< 500 ng g− 1) from the pre-Roman Iron Age (600 BC) until the first significant increases to ca. 1000–1800 ng g− 1 between 1700 and 1750 AD related to regional iron production. The highest increases in pyrogenic PAH concentrations occurred w…
Unraveling environmental histories from skeletal diaries — Advances in sclerochronology
2013
High-resolution proxy archives from aquatic settings are essential to better understand processes and mechanisms of global change. During the last decade, it has become increasingly evident that calcified tissues of bivalve mollusks and cold-water corals, in particular, can significantly increase our knowledge of seasonal to multi-decadal paleoclimate and paleoenvironmental variability in the extratropical oceans and coastal marine settings. Daily, tidal, fortnightly and annual growth patterns of periodically formed skeletal hard parts provide a means to place the proxy record in a precise temporal context. Their extreme longevity coupled with the running similarity between growth increment…
Carbon cycle and sea-water palaeotemperature evolution at the Middle-Late Jurassic transition, eastern Paris Basin (France).
2014
14 pages; International audience; A very high-resolution carbon and oxygen stable isotope analysis (bulk-carbonate) of a biostratigraphically well-constrained Callovian-Oxfordian series is provided here for the first time. The homogeneity of the clayey series and the weak diagenetic alteration allow the isotopic signal variations to be considered as primary in origin. A prominent and brief negative excursion in the δ13C curve (−2‰), occurring at the start of the Middle Callovian (Jason Zone - Obductum Subzone) and correlated regionally, suggests a possible methane release. The increasing δ13C values thereafter up to the Early Oxfordian, concomitant with a warming episode, highlight the buri…
教員 21 世紀型スキルに資するグローバル教員研修に関する実践的研究 ― Edu21st 尺度による自己効力感の変容に着目してー [Teachers’ self-efficacy on 21st century skills : A case study of an in-service teac…
2022
本研究の目的は，大学教員養成におけるグローバル教員研修が，大学院生（現 職教員・大学生）の「教員 21 世紀型スキル」に関する自己効力感にどのような変容を もたらすかを明らかにすることである。研修は，１ . 対話型ボトムアップ研修，２ ．フィン ランドの教育改革研修，及び，３ ．教科連携の CLIL・STEAM に拠る授業訪問を特徴 とする。次世代の児童・生徒が，学びを実社会へ転移するような教育を実現する教員の 21 世紀型スキルとは何か，国際間比較をとおした俯瞰的な研修を目指す。研究方法は， 『Edu 21st：教員 21 世紀型スキルの自己効力感尺度』の 47 質問項目をもちいた事前 と事後の変容，およびポートフォリオ記述分析である。その結果，Edu21st（３ 因子構 造）で差が認められ，「分析的デザイン思考能力」で最も変化が大きいことが明らかにな り，異分野連携の協働中に起こる異質な考えに対する葛藤への価値付けが見られた。 peerReviewed
Three existence theorems for weak contractions of Matkowski type
2010
We prove three generalizations of Matkowski’s fixed point theorems for weakly contractions.
Management of Patients with Gastric or Gastroesophageal Junction Cancer: From Theory to Integrated Clinical Path- ways Implementation in the Real Wor…
2022
Introduction: Best care of esophagogastric junction and gastric cancer (EGC) requires a complex, timely interaction between members of a multi-disciplinary team (MDT). An integrated clinical pathway (ICP) is necessary to achieve this goal as well as the implementation of its use in daily practice. The objective of this study was to elaborate on an integrated clinical pathway for the multi-disciplinary management of ECG. Authors also put in act an implementation program to improve adherence to guidelines thought an ICP. Method: This prospective work carried out by a multi-institutional MDT in Italy identified expert panel extracted relevant recommendations and/or statements from published pa…
