The literature on public perceptions of, and attitudes towards, nanotechnology used in the agrifood sector is reviewed. Research into consumer perceptions and attitudes has focused on general applications of nanotechnology, rather than within the agrifood sector. Perceptions of risk and benefit associated with different applications of nanotechnology, including agrifood applications, shape consumer attitudes, and acceptance, together with ethical concerns related to environmental impact or animal welfare. Attitudes are currently moderately positive across all areas of application. The occurrence of a negative (...) or positive incident in the agri-food sector may crystallise consumer views regarding acceptance or rejection of nanotechnology products. •Acceptance of agrifood nanotechnology based on perceptions of risk, benefit and ethics.•Attitudes towards nanotechnology in general are currently moderately positive.•Occurrence of a major nanotechnology-related "event" may crystallise consumer attitude.

Acute exercise consistently benefits both emotion and cognition, particularly cognitive control. We evaluated acute endurance exercise influences on emotion, domain-general cognitive control, and the cognitive control of emotion, specifically cognitive reappraisal. Thirty-six endurance runners, defined as running at least 30 miles per week with one weekly run of at least 9 miles (21 female, age 18-30 years) participated. In a repeated measures design, participants walked at 57% age-adjusted maximum heart rate (HRmax) (range 51-63%) and ran at 70% HRmax (range 64-76%) (...) for 90 minutes on two separate days. Participants completed measures of emotional state and the Stroop test of domain-general cognitive control before, every 30 minutes during, and 30 minutes after exercise. Participants also completed a cognitive reappraisal task after exercise. Functional near-infrared spectroscopy tracked changes in oxygenated and deoxygenated hemoglobin levels in the prefrontal cortex (PFC). Endurance exercise elevated positive emotion and cognitive reappraisal success. Endurance exercise reduced Stroop response time and test-evoked PFC oxygenation during exercise. Results suggest that even at relatively moderate intensities, endurance athletes benefit emotionally from running both during and after exercise, and task-related prefrontal cortex oxygenation reductions do not appear to hinder prefrontal-dependent cognitive control.

Les Theoremata d'esse et essentia (ca 1278-1285), qui, en depit d'une edition critique deja ancienne (Hocedez, 1930), n'avaient pas encore ete traduits integralement en francais a ce jour, apparaissent comme l'uvre majeure pour bien saisir la genese doctrinale et conceptuelle de la theorie de la distinction reelle. Peu de temps avant les Questions disputees sur l'etre et l'essence (1286-1287), qui sont au cur du debat entre Gilles de Rome (ca 1245-1316), partisan d'une distinction reelle entre l'etre et l'essence, et Henri (...) de Gand (ca 1217-1293), promoteur d'une theorie de la distinction " intentionnelle ", les Theoremes apparaissent comme un essai de synthese, dans lequel le maitre augustin donne un expose d'ensemble des arguments qui le conduisent a faire de l'etre une res (" chose " au sens de " realite ") a part entiere. Dans ces conditions, les disciples de Thomas d'Aquin (ca 1224-1274) n'ont pas manque de voir, en Gilles, l'un des partisans d'une these qu'ils revendiquaient comme un heritage de l'Aquinate. Les Theoremes revelent cependant une pensee incontestablement personnelle, et manifestent le caractere resolument original de Gilles de Rome, metaphysicien incontournable du XIIIe siecle finissant.

Few years pass without an attempt to interpret Theocritus, Idyll 7. The poem's narrative and descriptive skill, dramatic subtlety and felicity of language are mercifully more than adequate to survive these scholarly onslaughts, so I have less hesitation in offering my own interpretation. The poem's chief problems seem to me to arise from uncertainty as to: Who is the narrator, and why are we kept waiting until line 21 before we are told that he is called Simichidas? Who, or what (...) sort of man, is the goatherd Lycidas, whom he encounters on his way from town to the harvest festival? Answers to these questions fundamentally affect our interpretation of their exchange of songs, which occupies almost half the idyll, and of Lycidas' gift of his stick to Simichidas; and these interpretations will go far towards interpreting the poem as a whole.

post hos elefantorum fulgentium formidandam speciem et truculentos hiatus uix mentes pauidae perferebant; ad quorum stridorem odoremque et insuetum aspectum magis equi terrebantur. COKNELISSEN, Mnemosyne, xiv , 280, comments: ‘Non intellego fulgentium. Minime audiendus est Wagnerus, qui fulgentes elephantes dictos esse contendit ob cutem glabram. Corrigendum puto ingentium. Porro non satis intellego quomodo hiatus elefantorum militibus pauorem incutere potuerit. Wagnerus, qui omnia con-coquere solet, interpretatur proboscidas. Nescio an scripserit A. barritus.’.

The current article aims to provide an up-to-date synopsis of available techniques to study affect dynamics using intensive longitudinal data. We do so by introducing the following eight dichotomies that help elucidate what kind of data one has, what process aspects are of interest, and what research questions are being considered: single- versus multiple-person data; univariate versus multivariate models; stationary versus nonstationary models; linear versus nonlinear models; discrete time versus continuous time models; discrete versus continuous variables; time versus frequency domain; (...) and modeling the process versus computing descriptives. In addition, we discuss what we believe to be the most urging future challenges regarding the modeling of affect dynamics. (shrink)
