Strontium90 for determination of time since death
1999
Strontium90 (Sr90) is an artificial nuclear fission product of the atmospheric a-bomb testing between 1945 and 1979. It was spread throughout the atmosphere in the following years. Sr90 is an analogue to calcium and therefore enriched in human bones. Several studies especially in the 1960s and 1970s were undertaken to investigate the Sr90 burden and the resulting incorporated radiation in humans, but present studies are missing. In this study nine bone samples, three from 1931/32 and six from 1989 to 1994 were examined by measuring the Sr90 radiation. The samples from 1931/32 did not show any Sr90 activity. All the samples from 1989 and later showed a Sr90 activity, but the intensity was ve…
Timing in methods for studying psychosocial factors at work
2014
In the present chapter we focus on time lags in panel studies investigating psychosocial factors and stressor-strain relationships. First, a framework of theoretical reasons for choosing specific time lags is provided, which is based on the work by Frese and Zapf (Methodological issues in the study of work stress: objective vs. subjective measurement of work stress and the question of longitudinal studies. In: Cooper CL, Payne R (eds) Causes, coping and consequences of stress at work. Wiley, Chichester, pp 375–411, 1988). Although this theoretical framework provides a clear rationale for time intervals, researchers are frequently mistaken using it to derive appropriate time lags. Second, an…
Los efectos de la adversidad climática y sanitaria sobre la agricultura y la sociedad castellonense del siglo XVIII
2017
El presente artículo recurre a la microhistoria para analizar los archivos municipales de la Plana de Castelló, con el objetivo de obtener nuevas referencias sobre la evolución climática de la fachada mediterránea peninsular durante un periodo cronológico concreto: el siglo XVIII, enclavado en los estadios finales de la Pequeña Edad de Hielo. Con esta finalidad, se abordarán las principales sequías, precipitaciones extremas, plagas y epidemias acontecidas en la Plana de Castelló durante el Setecientos, y aquellos recursos, tanto religiosos como seculares, utilizados para prevenir, primero, y erradicar, después, las adversidades climáticas, biológicas y sanitarias. This paper discusses a mic…
Is physical activity a cause of longevity? It is not as straightforward as some would believe. A critical analysis
2018
There are discrepant findings between (A) observational follow-ups and (B) interventional studies that investigate possible causal association between high physical activity and low mortality. Participation in vigorous physical activity at a specific time-point is an indicator of good fitness and health, and is associated with a reduced risk of death. However, neither randomised controlled trials nor experimental animal studies have provided conclusive evidence to show that physical activity started during adulthood extends lifespan. Consequently, the undisputed health-related benefits of exercise have yet to translate into any proven causal relationship with longevity. Physical activity im…
Modeling interactions between political parties and electors
2017
In this paper we extend some recent results on an operatorial approach to the description of alliances between political parties interacting among themselves and with a basin of electors. In particular, we propose and compare three different models, deducing the dynamics of their related {\em decision functions}, i.e. the attitude of each party to form or not an alliance. In the first model the interactions between each party and their electors are considered. We show that these interactions drive the decision functions towards certain asymptotic values depending on the electors only: this is the {\em perfect party}, which behaves following the electors' suggestions. The second model is an …
The Concept of Value Beyond Economics: Social and Philosophical Roots for Corporate Social Responsibility
2017
This paper tries to underline the importance of the concept of value for CSR and then to map the concept of value beyond Economics. In doing this it takes in consideration the Italian literature in a specific time in order to make a first step for a broader research that takes in consideration also other literatures and time.
Scribe ergo quæ vidisti et quæ sunt et quæ oportet fieri post hæc
2018
Pasado, presente y futuro se dan cita en el fragmento del Apocalipsis. El pasaje mencionado constituye una invitación a reflexionar sobre el pasado, el presente y el futuro de una persona, de una institución o de una colectividad de cualquier terreno de especialización disciplinar en un momento concreto de su trayectoria en el que se pretende escrutar, valorar las formas cognoscitivas pretéritas y, con ellas, se aspira a redefinir el futuro de la investigación. En esta ocasión me propongo aplicarlo a los estudios relacionados con los testimonios escritos en su pluralidad de manifestaciones medievales.
COMPliance and Arthralgia in Clinical Therapy: the COMPACT trial, assessing the incidence of arthralgia, and compliance within the first year of adju…

5 Office-based Professional Association Gynecologic Oncologists e.V. in Germany (BNGO e.V.), Berlin; 6 Background: This prospective study evaluated the relationship between arthralgia and compliance during the first year of adjuvant anastrozole therapy in postmenopausal women with hormone receptor-positive early breast cancer. Patients and methods: COMPliance and Arthralgia in Clinical Therapy (COMPACT) was an open-label, multicenter, noninterventional study conducted in Germany. Patients had started adjuvant anastrozole 3-6 months before the study start. The primary end points were arthralgia, compliance, and the relationship between compliance and arthralgia, assessed at specific time poi…
