Canonical Variate Analysis of Sensory Profiling Data
2015
Principal Component Analysis (PCA) of product mean scores is generally used to obtain a product map from sensory profiling data. However, this approach does not take into account the variance of the product mean scores due to the individual panelist variability. Therefore, Canonical Variate Analysis (CVA) of the product effect in the two-way multivariate analysis of variance (MANOVA) should be considered as a natural alternative analysis to PCA. Indeed, it is the extension of the classical univariate approach used for the analysis of each descriptor separately. This analysis generates successive components maximizing product discrimination as measured by the usual Fisher statistics in analy…
Comparison of conventional descriptive analysis and a citation frequency-based descriptive method for odor profiling: An application to Burgundy Pino…
2010
International audience; The limitations of intensity scoring when describing the odor characteristics of a complex product have been documented in the literature. In the present work, the odor properties of 12 Burgundy Pinot noir wines were described by two independent panels performing, respectively, an intensity-based (conventional descriptive analysis) and a citation frequency-based method. Methods were compared according to three criteria: similarity of the sensory maps, control of panel performance and practical aspects. Intensity scoring and citation frequency data were analyzed, respectively, by Principal Components Analysis (PCA) and Correspondence Analysis (CA) followed by Hierarch…
Bank Loan Loss Accounting and Its Contracting Effects: The New Expected Loss Models
2019
As a result of the recent financial crisis, several key institutions urged the IASB and the FASB to re-evaluate their models for loan loss accounting and use more forward-looking information. The paper examines the principal features of the new expected loss approach, taking into account the tensions between accounting and prudential objectives with respect to credit losses. We discuss the rationales for the change introduced by IFRS 9 and explore the differences between the IASB and the FASB models. Based on the notions of accounting conservatism and earnings management, we discuss the potential consequences of the new models. While both the FASB and the IASB model are more conservative th…
Unveiling the Role of Multiple blockholders: Evidence from Closely Held Firms.
2019
Research Question/Issue. This paper disentangles how the modes of ownership distribution among multiple blockholders and their heterogeneity shape principal–principal conflicts and, in turn, affect firm performance. The paper offers empirical evidence from a panel of Italian closely held firms over the period 2009–2014. Research Findings/Insights. We explore the principal–principal conflicts among blockholders across two distinct control structures. When a single blockholder controls the firm, principal–principal conflicts are shaped by the trade‐off between the alignment effect and the monitoring effect. In this scenario, we find that the relationship between the two largest blockholders' …
The Sociology of Nazism
1994
In a previous paper, we tested a number of critical hypotheses derived from the three principal explanations of the sociology of Nazism. Our major finding was that the mass society, lower middle-class party of protest, and political confessionalism theses are empirically flawed. In this article, we apply an interest-based theory to the sociology of blue-collar Nazism. Using a sample of 15,006 workers who joined the Nazi Party between 1925 and 1932, we test the validity of our interest-based theory. The data demonstrate significant support for an interest-based account of Nazi Party working-class joining.
Orientation-invariance of individual differences in three face processing tasks
2019
Numerous studies have reported impairments in perception and recognition, and, particularly, in part-integration of faces following picture-plane inversion. Whether these findings support the notion that inversion changes face processing qualitatively remains a topic of debate. To examine whether associations and dissociations of the human face processing ability depend on stimulus orientation, we measured face recognition with the Cambridge Face Memory Test (CFMT), along with experimental tests of face perception and selective attention to faces and non-face objects in a sample of 314 participants. Results showed strong inversion effects for all face-related tasks, and modest ones for non-…
Statistical analysis of sensory profiling data. Graphs for presenting results (PCA and ANOVA)
2000
Abstract A principal component analysis is performed to analyse the matrix of median values, with 16 varieties in rows, and all descriptors in columns. Only texture descriptors contribute to the definition of the main axes. Six varieties are identified that score high on mealiness and low on moisture, the 10 other varieties are ordered according to a mashable axis which involves texture descriptors. Next we exclude texture descriptors since the main characteristics are already found, and mealy varieties since they are not suitable for steamed potatoes. A mixed linear model (ANOVA) with random subject effects is then used for each descriptor. Flavour and taste differences are found among the…
Brauer correspondent blocks with one simple module
2019
One of the main problems in representation theory is to understand the exact relationship between Brauer corresponding blocks of finite groups. The case where the local correspondent has a unique simple module seems key. We characterize this situation for the principal p-blocks where p is odd.
Las técnicas de reproducción asistida en la jurisprudencia y en el cine de los Óscar
2018
El paso del tiempo y los grandes avances técnicos han dado lugar a que se puedan tener hijos no solo de forma biológica o por adopción sino también mediante otras técnicas o tratamientos médicos que facilitan el embarazo cuando éste no se consigue de forma natural. Actualmente, los principales tratamientos de fertilidad son la inseminación artificial y la fecundación in vitro (FIV). En este artículo se abordan las técnicas de reproducción asistida desde dos puntos de vista: el fílmico, analizando algunas películas que han sido nominadas a los Óscar en época reciente; y el jurídico, viendo la regulación legal y algunas de las sentencias más relevantes existentes hasta la fecha sobre este tem…
Contenido de la carta individual de extinción en el marco del despido colectivo : Incidencia sobre la afectación de trabajadoras embarazadas
2021
La presente obra analiza los principales pronunciamientos judiciales en relación al contenido de la carta individual de despido derivado de un despido colectivo. Se discute sobre la conveniencia de incluir la causa en la carta, así como los criterios de selección del trabajador afectado. La cuestión tiene una especial incidencia sobre un colectivo concreto: las trabajadoras embarazadas.
