The Career Satisfaction Scale: Longitudinal measurement invariance and latent growth analysis

The present research analyses the adequacy of the widely used Career Satisfaction Scale (CSS; Greenhaus, Parasuraman, & Wormley, 1990) for measuring change over time. We used data of a sample of 1,273 professionals over a 5-year time period. First, we tested longitudinal measurement invariance of the CSS. Second, we analysed changes in career satisfaction by means of multiple indicator latent growth modelling (MLGM). Results revealed that the CSS can be reliably used in mean change analyses. Altogether, career satisfaction was relatively stable over time; however, we found significant variance in intra-individual growth trajectories and a negative correlation between the initial level of and changes in career satisfaction. Professionals who were initially highly satisfied became less satisfied over time. Theoretical and practical implications with respect to the construct of career satisfaction and its development over time (i.e., alpha, beta, and gamma change) are discussed.

Identifying observable criteria defining a critical situation involving football fans: an expert focus group study

Critical situations (CSs) involving football fans is a well-researched phenomenon with most studies examining factors leading to an escalation of violence (e.g. Braun & Vliegenthart, 2008). However, research so far has fallen short of analysing CSs that do not escalate (e.g. Hylander & Guvå, 2010) as well as establishing observable criteria that constitute such CSs. Granström et al. (2009), for instance, put forward a definition of a CS describing such situations as characterised by a discrepancy between peace and war-making behaviours between police and demonstrators. Still, this definition remains vague and does not provide concrete, defining criteria that can be identified on site. The present study looks beyond fans’ violent acts per se and focuses on these situations with a potentially – but not necessarily - violent outcome. The aim of this preliminary study is to identify observable criteria defining such a CS involving football fans. This focus group comprised of five experts working with football fans in the German-speaking area of Switzerland who discussed observable characteristics of a CS. Inductive content analysis led to the identification of specific criteria such as, “arrest of a fan”, “insufficient distance (<30m) between fans and police” and “fans mask themselves”. These criteria were then assigned to four phases of a CS highlighting the dynamic aspect of this phenomenon: Antecedents, Causes, Reactions, Consequence. Specifically, Causes, Reactions and Consequences are observable on site, while Antecedents include relevant, background information directly influencing a CS. This study puts forward a working definition of a CS that can facilitate the assessment of actual situations in the football context as well as for further research on fan violence prevention and control. These results also highlight similarities with studies investigating fan violence in other European countries while acknowledging unique characteristics of the Swiss German fan culture.

Durazneros bajo tela antigranizo : efectos sobre la madurez y calidad

Para evaluar la influencia de la tela antigranizo sobre la calidad de duraznos para industria cv. Dr. Davis en dos fechas de cosecha se determinó la madurez y calidad de frutos de plantas testigo y bajo tela antigranizo. Los parámetros medidos fueron peso, intensidad de color de piel y de pulpa, firmeza de pulpa, contenido de sólidos solubles (CSS), acidez titulable (AT) y relación CSS/AT. La tela antigranizo no afectó el peso de los frutos. En cambio retrasó su maduración y disminuyó su calidad. El color de piel y pulpa, el CSS y la relación CSS/AT fueron menores en las plantas bajo tela antigranizo pero, en sus frutos, la firmeza de pulpa fue mayor.

Ciruelas bajo tela antigranizo : : efecto sobre la calidad

Se evaluó la influencia de la tela antigranizo en la calidad en cosecha y postcosecha de ciruelas japonesas (Prunus salicina Lindl.) cv. Angeleno. Se cosechó fruta de plantas bajo tela y sin tela en dos fechas. Las determinaciones de madurez y calidad se hicieron en cosecha, después de 45 y 60 días de almacenamiento refrigerado (0 °C y HR = 85 %) y luego de un período de maduración a 20 °C. Parámetros considerados: tamaño, color, firmeza de pulpa, contenido de sólidos solubles, pH, acidez titulable, relación CSS/AT, deshidratación y desórdenes fisiológicos (harinosidad). Se realizó un análisis factorial teniendo en cuenta tela antigranizo (T), fecha de cosecha (F) y período de almacenamiento refrigerado (P). Los factores T y F actuaron sobre el tamaño, color de piel, firmeza de pulpa, CSS, AT y CSS/AT en las evaluaciones realizadas en cosecha. Después del período de maduración, los factores T, F y P tuvieron principalmente efecto en la firmeza de pulpa, AT y CSS/AT. La fecha de cosecha y el período de almacenamiento tuvieron una marcada influencia sobre la incidencia de harinosidad.

Ciruela japonesa : : parámetros de madurez y calidad

Durante la maduración de frutos de ciruela japonesa [Prunus salicina (Lindl.)] cv. Black Amber, Laroda y Angeleno se evaluaron parámetros de madurez y calidad. Semanalmente se midió la intensidad de color superior de la piel y porcentaje de cubrimiento; firmeza de pulpa; sólidos solubles (CSS) y acidez titulable (AT). Para cada parámetro se ajustó un modelo matemático de correlación con la variable tiempo. El color se desarrolló temprano durante la maduración en Black Amber y Angeleno. La firmeza de pulpa disminuyó a velocidad constante. El ablandamiento en Angeleno fue lento (0,16 lb/día) y rápido, en Black Amber (0,36 lb/día) y Laroda (0,26 lb/día). El incremento de sólidos solubles fue escaso en Black Amber y mayor en cv. Laroda y Angeleno.

La tela antigranizo en la maduración de ciruelas japonesas : : Prunus salicina Lindl

Se evaluó el efecto de la tela antigranizo sobre la evolución de la maduración de las cv. Linda Rosa y Larry Ann de ciruelo japonés. Periódicamente se cosechó fruta de plantas uniformes: ambas situaciones bajo tela y sin protección. Los parámetros de madurez y calidad evaluados fueron: peso, diámetros, color de piel, firmeza de pulpa, contenido de sólidos solubles (CSS), acidez titulable (AT) y la relación CSS/AT. La tela afectó la calidad de los frutos. El contenido de solubles y el color piel de la cv. Linda Rosa y el tamaño de frutos de la cv. Larry Ann, atributos de calidad muy valorados, fueron menores en las plantas bajo tela.

Evaluación de características de interés agronómico de damascos cv. Modesto

El cultivar de damascos Modesto es de introducción relativamente reciente en Mendoza (Argentina). El objetivo del trabajo fue evaluar las siguientes características de interés agronómico: la época de floración y la calidad de los frutos en cosecha y en postcosecha. El estudio se realizó en un monte comercial durante 2007 y 2008. Se registraron tres estados fenológicos: "D" (corola visible), "F" (flor abierta) y "H" (fruto cuajado). Se estableció el inicio de la floración, la plena floración y el fin de la misma. En los frutos las evaluaciones y mediciones se realizaron en el momento de la recolección y después del período de maduración de la fruta conservada en cámara frigorífica. Se determinó: color de fondo, peso, diámetro, firmeza de pulpa, contenido de sólidos solubles, pH, acidez titulable, presencia de hongos y desórdenes fisiológicos. Los resultados muestran que el cultivar Modesto florece en una época intermedia en la zona E de la provincia de Mendoza. La fecha de plena floración en los dos años del estudio fue el 8 de setiembre. En los estados de madurez evaluados los frutos reúnen los atributos de calidad demandados por el consumidor: alto CSS, color anaranjado en la madurez, buena firmeza de pulpa; sin embargo, el rápido, descenso de la firmeza durante la maduración en poscosecha obliga a una comercialización acelerada. Después del almacenamiento en cámara frigorífica durante treinta días y un período de maduración de dos días, la futa presentó el desorden harinosidad con una incidencia superior al 60%; esto señala que el cv. Modesto no puede almacenarse por un período tan prolongado.

Pore water geochemistry of Håkon Mosby mud volcano sediments measured at station PS74/169-1_PUC-15 (Z1-S1, new flow surface)

Pore water and turnover rates were determined for surface sediment cores obtained in 2009 and 2010. The pore water was extracted with Rhizons (Rhizon CSS: length 5 cm, pore diameter 0.15 µm; Rhizosphere Research Products, Wageningen, Netherlands) in 1 cm-resolution and immediately fixed in 5% zinc acetate (ZnAc) solution for sulfate, and sulfide analyses. The samples were diluted, filtered and the concentrations measured with non-suppressed anion exchange chromatography (Waters IC-Pak anion exchange column, waters 430 conductivity detector). The total sulfide concentrations (H2S + HS- + S**2-) were determined using the diamine complexation method (doi:10.4319/lo.1969.14.3.0454). Samples for dissolved inorganic carbon (DIC) and alkalinity measurements were preserved by adding 2 µl saturated mercury chloride (HgCl2) solution and stored headspace-free in gas-tight glass vials. DIC and alkalinity were measured using the flow injection method (detector VWR scientific model 1054) (doi:10.4319/lo.1992.37.5.1113). Dissolved sulfide was eliminated prior to the DIC measurement by adding 0.5 M molybdate solution (doi:10.4319/lo.1995.40.5.1011). Nutrient subsamples (10 - 15 ml) were stored at - 20 °C prior to concentration measurements with a Skalar Continuous-Flow Analyzer (doi:10.1002/9783527613984).
