Recent changes in chironomid communities and hypolimnetic oxygen conditions relate to organic carbon in subarctic ecotonal lakes
2018
A key question in aquatic elemental cycling is related to the influence of bottom water oxygen conditions in regulating the burial and release of carbon under climate warming. In this study, we used head capsules of Chironomidae larvae to assess community and diversity change between the past (estimated as Pre-Industrial Period) and present and to reconstruct changes in hypolimnetic oxygen conditions from 30 subarctic ecotonal lakes (northeastern Lapland) using the top-bottom paleolimnological approach applying surface sediment (topmost 0-2 cm) and reference (4-5 cm) samples. Subsequently, we tested the findings against dissolved organic carbon (DOC) concentration of the sites. We found tha…
Combining Sequence Analysis and Hidden Markov Models in the Analysis of Complex Life Sequence Data
2018
Life course data often consists of multiple parallel sequences, one for each life domain of interest. Multichannel sequence analysis has been used for computing pairwise dissimilarities and finding clusters in this type of multichannel (or multidimensional) sequence data. Describing and visualizing such data is, however, often challenging. We propose an approach for compressing, interpreting, and visualizing the information within multichannel sequences by finding (1) groups of similar trajectories and (2) similar phases within trajectories belonging to the same group. For these tasks we combine multichannel sequence analysis and hidden Markov modelling. We illustrate this approach with an …
PURSUING A CUSTOMER-DRIVEN APPROACH FOR INNOVATION AND MARKETING EXCELLENCE
2011
Nowadays, innovation goes so much further than merely products. In order to thrive in this extremely competitive business environment a company needs to innovate its technologies, its business strategies, its business models, and by innovating in research. It is also about reinventing or building new markets in order to meet, satisfy and delight untapped consumer needs, wants, and desires. However, considering the new opportunities and threats that Internet, globalization, and hypercompetition have on an organization’s activity regarding selecting and executing the right ideas, right products, and delivering them through the right channels in record time, at the right prices, while promotin…
Do opposite ends of same factors underlie life satisfaction vs. depressive symptoms among older people?
2021
Abstract Background Although depressive symptoms are more common among older than younger age groups, life satisfaction tends to remain stable over the life course, possibly because the underlying factors or processes differ. Aim To study whether the factors that increase the likelihood of high life satisfaction also decrease the likelihood of depressive symptoms among older people. Methods The data were a population-based probability sample drawn from community-dwelling people aged 75, 80, and 85 years (n = 1021). Participants’ life satisfaction was measured with the Satisfaction with Life Scale and depressive symptoms with the Centre for Epidemiologic Studies Depression Scale (CES-D). Phy…
Internal resources as tools to increase the global competition: the Italian wine industry case
2017
Purpose The purpose of this paper is twofold: first, it identifies distinct organizational models in a sample of small and medium enterprises operating in the Sicilian wine industry; and second, it identifies the key factors enabling a superior export success. Design/methodology/approach Internal resources were analyzed theoretically in order to achieve the aims of the study. Subsequently the empirical investigation was carried out administering a questionnaire to a sample of 102 wineries in Sicily, Italy. A cluster analysis was performed in order to group these firms into homogeneous categories. Findings The findings show that success in the international market is more common among winer…
Antecedent variables of innovation behaviors in organizations: Differences between men and women
2016
Abstract Introduction Relevance of innovation behaviors for organizational success led to study its main individual, job-related and organizational antecedents. Moreover, research on differences in innovation between men and women showed inconclusive results. Ambidexterity (Bledow, Frese, Anderson, Erez, & Farr, 2009) and Zhou and Hoever (2014) call for combining contextual and personal characteristics in innovation research suggest that pathways and variables leading to innovation between men and women could be different. Objective(s) This study aims to analyze if men and women differ in the main antecedents for innovative behaviors. Thus, a moderating effect of gender on the relationship …

The statistical analysis demonstrated significant differences in the parenting stress of children with ADHD and low and high scores on the attributes of self-awareness, proactivity, perseverance and go…
Acculturation Profiles and Perceived Discrimination: Associations with Psychosocial Well-being Among Tunisian Adolescents in Italy
2015
Research usually analyzed the relationships between acculturation or perceived discrimination and immigrants’ well-being, but few studies used an integrative perspective. Framed from a person-oriented approach, the current paper tried to advance the literature examining how acculturation profiles and perceived (group and personal) discrimination were associated with psychosocial well-being in a sample of 348 Tunisian adolescents (females = 48.28%; mean age = 15.72) living in southern Italy. Cluster analytic methods on the scores of acculturation strategies, ethnic and national identities, ethnic and national languages, ethnic and national peer social contacts produced three acculturation pr…

Crisis Communication Competence in Co-Producing Safety with Citizen Groups
2016
The aim of this article is to explore interpersonal communication competence needed by crisis communication and management experts when co-operating with citizen groups in response to emergencies. Moreover, the purpose is to understand how response organizations can further develop this crisis communication competence and so contribute to the functioning of response networks. The research task is approached qualitatively by eliciting crisis communication and management experts’ (n = 33) perceptions of the interpersonal communication competence response organizations needs when co-operating with citizen groups. The data were gathered via an international online questionnaire using a method r…
