PurposeThe purpose of this study was to evaluate the measurement structure of a simplified version of the Multiple Sclerosis Self-Management Scale (MSSMS) in a sample of 256 individuals with multiple sclerosis (MS).MethodsExploratory factor analysis was utilized to uncover meaningful and interpretable factors.ResultsThe study yielded three factors as both meaningful and interpretable (medication compliance, MS knowledge, and health maintenance behavior). These factors are reliable and correlated with functional disability and community participation in the theoretically expected directions.ConclusionResults show the MSSMS to be a promising rehabilitation assessment tool for individuals with MS and rehabilitation counselors to evaluate self-management support needs in the interview, assessment, and rehabilitation planning protocols.

Genetic parameters were estimated for 2403 purebred Yorkshire pigs over a 2-yr period, representing 21 sires. The traits studied included average daily gain, age adjusted to 90 kg, ultrasonic measurements of backfat at the mid-back and loin positions, total and adjusted total ultrasonic backfat and corresponding carcass backfat measurements. Least squares analyses were used to estimate and adjust for the effects of sex, year-season and sex by year-season interaction. Heritabilities and genetic correlations were calculated for all traits using both half- and full-sib estimates. Adjusted age and adjusted total ultrasonic backfat measurements were found to have the highest heritabilities of the live traits in this study. Estimates of heritability for adjusted age and adjusted total ultrasonic backfat were 0.24 ± 0.10 and 0.26 ± 0.10 based on half-sib and 0.56 ± 0.07 and 0.41 ± 0.06 from full-sib analyses. The genetic correlation between these two traits was −0.07 ± 0.28 based on the half-sib method. The total phenotypic correlation was −0.01 ± 0.02.

Abstract Climate change affects the Mediterranean region stressing lentil crops during flowering and seed set. Early maturation and drought tolerance are desirable traits in these conditions. Phosphorus (P) is considered to enhance early flowering, maturity and thus yields. Four P rates (0, 30, 60, 90 kg P2O5 ha−1) were applied on four cultivars (Samos, Thessaly, Flip, Ikaria) during two seasons. Growing degree-days (GDD) were calculated for vegetative (V4–5, V7–8) and reproductive stages (R1, R2, R4, R6, R8). At R2 (full bloom) carbon isotope discrimination (Δ) was used to assess water-use efficiency. At R8 (full maturity), the seed weight (SW) was determined by harvest. Cultivars, P and the P × cultivar and P × growth season interactions affected the earliness in reproductive stages; P had no effect on GDD of vegetative stages. Phosphorus both induced earliness (Flip, Thessaly) and delayed maturity (Samos, Ikaria). GDD and SW were negatively correlated for the P × cultivar interaction at R1 (first bloom), R2, R4 (flat pod) and R6 (full pod filling) stages; being the strongest at R1. Negative correlations were evident for the P × growth season interaction at R2, R4 and R6 stages; being the strongest at R4. Cultivars and P did not affect Δ. A proper combination of cultivar and P rate can mitigate lentil yield losses under changing Mediterranean climate.

ABSTRACT Objective. To determine the effect of environmental factors on litter traits at birth and weaning, and their repeatabilities in four farms in the sub-humid tropics of Mexico. Materials and methods. Data from 46.249 to 50.316 litters for litter size at birth (LSB), number of piglets born alive (NBA), litter weight at birth (LWB), number of piglets weaned (NPW) and litter weight at weaning (LWW) were used. The statistical model for LSB, NBA and LWB included the effects of farm, farrowing year, farrowing season, parity number, simple interactions, random effects of sow and the error term. NPW and LWW were analyzed using the previous model plus the linear and quadratic effects of lactation length (LL). Results. The means for LSB, NBA, LWB, NPW and LWW were 11.7 piglets, 11.0 piglets, 16.1 kg, 10.3 piglets and 61.3 kg, respectively. All effects in the model affected the litter traits. Farrowing year x season interaction was significant for NPW, LWB and LWW. The dry season had the highest LSB, NBA y NPW. First parity sows had higher LSB and NBA means than for second parity sows. Parity increase until parity 4 to decrease thereafter. LL had a quadratic effect on NPW and LWW. Repeatability estimates for LSB, NBA, and LWB were 0.12, 0.12 and 0.14, respectively. Conclusions. All traits studied were influenced by the environmental factors studied. Repeatabilities for LSB, NBA and LWB were low. RESUMEN Objetivo. Determinar el efecto de factores ambientales sobre características de la camada al nacer y al destete, y sus repetibilidades en cuatro granjas en el trópico sub-húmedo de México. Materiales y métodos. Se utilizaron los datos de 50.316 a 46.249 camadas para el total de lechones nacidos (LSB), lechones nacidos vivos (NBA) y peso de la camada al nacimiento (LWB), lechones destetados (NPW) y peso de la camada al destete (LWW). El modelo estadístico para LSB, NBA y LWB incluyen los efectos de granja, año, época, número de parto, interacciones simples, efecto aleatorio de cerda y error. El modelo para NPW y LWW incluyó los factores anteriores y además, los efectos lineal y cuadrático de largo de lactación (LL). Resultados. Las medias para LSB, NBA, LWB, NPW y LWW fueron 11.7 lechones, 11.0 lechones, 16.1 kg, 10.3 lechones y 61.3 kg, respectivamente. Todos los factores estudiados afectaron las características de la camada. La interacción de año x época fue significativa para NPW, LWB y LWW. La época seca presentó las mayores medias de LSB, NBA y NPW. Las cerdas primer parto obtuvieron medias de LSB y NBA superiores que las cerdas del segundo parto. Las medias por número de parto incrementaron hasta el cuarto, para después disminuir. La LL obtuvo un efecto cuadrático sobre NPW y LWW. Las repetibilidades estimadas para LSB, NBA, y LWW fueron 0.12, 0.12 y 0.14, respectivamente. Conclusiones. Todos los factores ambientales estudiados afectaron las características de la camada al nacer y al destete. Las repetibilidades estimadas fueron bajas.

Penelitian ini bertujuan untuk mengetahui noninependensi relationship maintenance behavior pada pasangan suami istri yang menjalani hubungan jarak jauh. Partisipan terdiri dari 52 pasangan. Data diambil dengan teknik snowball sampling. Relationship maintenance behavior diukur dengan skala Relational Maintenance Behavior Measure (RMBM) dari Stafford (2011). Teknik analisis yang digunakan adalah dyadic analysis. Hasil analisis menunjukkan adanya nonindependensi relationship maintenance behavior pada pasangan suami istri yang menjalani hubungan jarak jauh. Dengan demikian, dapat disimpulkan adanya saling ketergantungan dan kesamaan perilaku relationship maintenance behavior pada pasangan yang menjalani hubungan jarak jauh.

Effect Of Age

Survival Kit V3.12 was used to analyse the length of productive life of cattle in theCzechRepublic. The data set consisted of 230 028 registeredHolstein cows. The model included the time-dependent effects parity × stage of lactation interaction, herd × year × season interaction, class of milk production within herd and year, breed within years and the time-independent effect of age at first calving and the random effect of sire. The highest risk of culling was found for cows at the beginning and at the end of the first lactation and at the end of any other lactation. The risk of culling decreased with parity. The risk of culling of cows assigned to the lowest milk production class was five times higher than that of cows assigned to the average milk production class. Risk of culling diminished with a decreasing percentage ofHolstein breed. Cows younger at first calving showed a lower risk of culling. Breeding values for sires expressed as a risk ratio of their daughters were between 0.7 and 1.45. Estimated heritability of functional longevity was 0.025 on the log scale and 0.041 on the original scale.
