Evolutionary processes in the emergence and recent spread of the syphilis agent, Treponema pallidum
2022
Abstract The incidence of syphilis has risen worldwide in the last decade in spite of being an easily treated infection. The causative agent of this sexually transmitted disease is the bacterium Treponema pallidum subspecies pallidum (TPA), very closely related to subsp. pertenue (TPE) and endemicum (TEN), responsible for the human treponematoses yaws and bejel, respectively. Although much focus has been placed on the question of the spatial and temporary origins of TPA, the processes driving the evolution and epidemiological spread of TPA since its divergence from TPE and TEN are not well understood. Here, we investigate the effects of recombination and selection as forces of genetic diver…
Values that Underlie and Undermine Well–Being: Variability across Countries
2017
We examined relations of 10 personal values to life satisfaction (LS) and depressive affect (DEP) in representative samples from 32/25 countries ( N = 121 495). We tested hypotheses both for direct relations and cross–level moderation of relations by Cultural Egalitarianism. We based hypotheses on the growth versus self–protection orientation and person–focus versus social–focus motivations that underlie values. As predicted, openness to change values (growth/person) correlated positively with subjective well–being (SWB: higher LS, lower DEP) and conservation values (self–protection/social) correlated negatively with SWB. The combination of underlying motivations also explained more comple…
Voice and Culture: A Prospect Theory Approach
2014
The present study examines the congruence of individuals' minimum preferred amounts of voice with the prospect theory value function across nine countries. Accounting for previously ignored minimum preferred amounts of voice and actual voice amounts integral to testing the steepness of gain and loss functions explicated in prospect theory, we use curve fitting to show that ratings of procedural justice fit prospect theory's value function specifically. Further, we investigate the form of this function across nine countries that range in power distance. Results suggest that the form of the value function is congruent with prospect theory, showing an S-shaped curve that is steeper in the loss…
Spacelike energy of timelike unit vector fields on a Lorentzian manifold
2004
On a Lorentzian manifold, we define a new functional on the space of unit timelike vector fields given by the L2 norm of the restriction of the covariant derivative of the vector field to its orthogonal complement. This spacelike energy is related with the energy of the vector field as a map on the tangent bundle endowed with the Kaluza–Klein metric, but it is more adapted to the situation. We compute the first and second variation of the functional and we exhibit several examples of critical points on cosmological models as generalized Robertson–Walker spaces and Godel universe, on Einstein and contact manifolds and on Lorentzian Berger’s spheres. For these critical points we have also stu…
Random Tanglegram Partitions (Random TaPas): An Alexandrian Approach to the Cophylogenetic Gordian Knot
2018
Abstract Symbiosis is a key driver of evolutionary novelty and ecological diversity, but our understanding of how macroevolutionary processes originate extant symbiotic associations is still very incomplete. Cophylogenetic tools are used to assess the congruence between the phylogenies of two groups of organisms related by extant associations. If phylogenetic congruence is higher than expected by chance, we conclude that there is cophylogenetic signal in the system under study. However, how to quantify cophylogenetic signal is still an open issue. We present a novel approach, Random Tanglegram Partitions (Random TaPas) that applies a given global-fit method to random partial tanglegrams of …
Identity Processes in Adulthood: Diverging Domains
2005
Patterns of identity formation were analyzed in a longitudinal framework, from ages 27 to 36 and then to 42 years of age. Information from all 3 ages was available for 197 participants (100 women, 97 men). A variation of Marcia’s (1966) Identity Status Interview included 5 domains: religious beliefs, political identity, occupational career, intimate relationships, and lifestyle. Great variability in identity status assessments was found across the domains at each age level. The domains representing work and family (occupation, relationships, and lifestyle) were more salient for middle- aged adults than were ideological domains (religion and politics). Development along the hypothesized sequ…
Values and subjective well-being
2018
Research on relations of personal values to subjective well-being has begun to flourish only recently. This is surprising because our values represent what we consider important and worth pursuing in life, and our subjective well-being (henceforth SWB) represents how happy and satisfied we are with the life we are leading. This chapter summarizes what we know about value—SWB relations and identifies some of what we do not know but would like to know. We first discuss the nature of values and the structured system they form. We then note three theoretical perspectives on relations of values to SWB (Sagiv & Schwartz, 2000; Sagiv, Roccas & Hazan, 2004). The first perspective seeks to explain d…
The Influence of the Congruence Between Brand and Consumer Personality on the Loyalty to Print and Online Issues of Magazine Brands
2012
An important development in the theory of brands has been the concept of a brand personality as part of the brand image. The construct of congruence relates the personality of brands to the self-concept of consumers. It is assumed that congruence between the recipient's perception of his or her own personality and his or her perception of the brand personality leads to a higher degree of loyalty. The congruence construct has been proven to be a loyalty-promoting factor in various studies for consumer good brands. Whether the influence of congruence also exists with regard to media brands has, however, not yet been examined. As a step to close the gap, this research explores the effects of c…
Intercultural customer service encounters : a behavioral study of satisfactory and unsatisfactory service outcomes
2012
Ulkomaalaistaustaisten asukkaiden ja turistien määrä Suomessa on kasvanut huomattavasti viime vuosien aikana. Yritysten resurssien ohjaaminen tämän alati kasvavan ja ostovoimaisen asiakaskunnan tarpeiden huomioimiseen voisi edistää asiakaspalvelualan yritysten liiketoimintaa. Tällä hetkellä on kuitenkin epäselvää miten hyvin ulkomaalaisten asiakkaiden erityistarpeet on huomioitu suomalaisessa asiakaspalvelussa. Tutkimuksen tavoitteena oli tutkia asiakastyytyväisyyttä kulttuurienvälisissä asiakaspalvelutilanteissa Suomessa. Kvalitatiivinen tutkimus suoritettiin puoli-strukturoitujen teemahaastatteluiden avulla ja haastateltaviksi valittiin joukko ulkomaalaisia vaihto- ja tutkinto-opiskelijoi…
Investigating occupational well-being and leadership from a person-centred longitudinal approach: congruence of well-being and perceived leadership
2015
The overall objective of this longitudinal study was to investigate the association between perceived leadership and employee well-being from a person-centred approach utilizing the principles of the conservation of resources theory (Hobfoll, S. E. (1989). Conservation of resources: A new attempt at conceptualizing stress. American Psychologist, 44, 513–524; Hobfoll, S. E. (2002). Social and psychological resources and adaptation. Review of General Psychology, 6, 307–324). First, we aimed to identify latent classes (i.e., subgroups) of employees that demonstrated similar mean levels of stability and change in occupational well-being (i.e., vigour and emotional exhaustion) across a mean time…
