A physiological profile approach to animal temperament: How to understand the functional significance of individual differences in behaviour

Animal behaviour research has experienced a renewed interest in consistent individual differences (i.e. animal personality or temperament). Recent ecological studies have identified environmental conditions that give rise to the development and evolution of temperaments and to fitness-related outcomes of temperament. Additional literature has also described relationships between temperaments and physiological regulation. However, one-to-one relationships between one behavioural trait and one physiological system do not account for co-selection of behavioural and physiological traits, nor the complex signalling among physiological systems. In the current paper, we review the literature on multiple physiological processes associated with temperament, propose temperament-specific physiological profiles, and focus on next steps to understand the functional significance, evolution and maintenance of temperaments. We propose that to understand causes and consequences of temperament we need to characterize integrative physiological profiles associated with different temperaments.

Accuracy in perceptions of a partner’s sexual goals

Intimate partners engage in sex for a variety of reasons, and their perceptions of each other’s sexual goals play an important role in intimate relationships. How accurate are these perceptions of a partner’s sexual goals and is accuracy associated with relationship quality and sexual satisfaction for the couple? To answer these questions, we conducted a 21-day dyadic daily experience study of 121 couples, which we analyzed using two different approaches to examine accuracy: the profile approach and the Truth and Bias Model. Results from these two approaches demonstrated that people’s perceptions of their partner’s sexual goals were indeed accurate, but that accuracy was not associated with relationship quality or sexual satisfaction for the perceiver or their partner. Rather, perceiving a partner’s sexual goals in normative (or socially desirable) ways was associated with relationship quality and sexual satisfaction for both the perceiver and their partner. Implications of these findings are discussed.

Testing Two Theories of Criminal Careers: A Criminal Career Profile Approach

<p>Criminal career research has emerged as a field interested in determining the factors related to the onset, frequency, duration, maintenance, and desistance of criminal behaviour (Blumstein & Cohen, 1987; Blumstein, Cohen, & Farrington, 1988). Various theories have been developed to account for these components of the criminal career, and the present research aims to examine the desistance components of two such theories in a sample of high risk adult offenders. Looking first at Moffitt’s (1993) adolescencelimited/ life-course persistent perspective, and then at Laub and Sampson’s (1993; Sampson & Laub, 2005) theory of informal social controls, there is limited evidence that either frequency of conviction or criminal career seriousness in high risk adult offenders can be explained well by reference to either of these theories alone. Although components of each theory appear to have some support within this sample, it is important to note that the prediction of future seriousness appears to be particularly difficult. Implications of these findings are discussed, with particular reference to policy concerns and areas for additional research.</p>

Artemisia annua Growing Wild in Romania—A Metabolite Profile Approach to Target a Drug Delivery System Based on Magnetite Nanoparticles

The metabolites profile of a plant is greatly influenced by geographical factors and the ecological environment. Various studies focused on artemisinin and its derivates for their antiparasitic and antitumoral effects. However, after the isolation and purification stage, their pharmaceutical potential is limited due to their low bioavailability, permeability and lifetime. The antibacterial activity of essential oils has been another topic of interest for many studies on this plant. Nevertheless, only a few studies investigate other metabolites in Artemisia annua. Considering that secondary metabolites act synergistically in a plant, the existence of other metabolites with antitumor and high immunomodulating activity is even more important. Novel nano-carrier systems obtained by loading herbs into magnetic nanoparticles ensures the increase in the antitumor effect, but also, overcoming the barriers related to permeability, localization. This study reported the first complete metabolic profile from wild grown Romanian Artemisia annua. A total of 103 metabolites were identified under mass spectra (MS) positive mode from 13 secondary metabolite categories: amino acids, terpenoids, steroids, coumarins, flavonoids, organic acids, fatty acids, phenolic acids, carbohydrates, glycosides, aldehydes, hydrocarbons, etc. In addition, the biological activity of each class of metabolites was discussed. We further developed a simple and inexpensive nano-carrier system with the intention to capitalize on the beneficial properties of both components. Evaluation of the nano-carrier system’s morpho-structural and magnetic properties was performed.

Why Do People Work? An Empirical Test of Hybrid Work Orientations

The present study analyzed whether one’s work orientation can be organized into work orientation profiles beyond the three pure orientations of job, career, and calling. We tested the existence of these hybrid work orientations in a sample of 959 adults aged from 18 to 71 years old (M = 40.61, SD = 9.54). A cluster analysis showed that the best result consisted of four profiles: “Career-Calling”, “Career-Job”, “Pure Job”, and “Indifference”. Theoretical and practical implications of profile approach to the study of work orientations are discussed at the end.

Striving for inclusion: evidence from China using a latent profile approach

Purpose This study aims to identify profiles of inclusion in the workplace to provide evidence-based guidance to build an inclusive organization. Design/methodology/approach Latent profile analysis (LPA), a person-centred classification analytical tool, was applied to determine the subtypes of inclusion with Mplus 7.4, using two-wave data collected from 368 employees in 8 Chinese companies. Findings Three subgroups were identified: identity inclusion group (the highest level of inclusion, 34.0%), value inclusion group (the moderate level of inclusion, 47.5%) and low inclusion group (the lowest level of inclusion, 18.5%). The findings indicate that groups with male, aged and highly educated members, as well as members from developed areas generally tend to feel more included and greater inclusion relates to more favourable outcomes and fewer detrimental consequences. Research limitations/implications As this study was conducted only in China, the results may not be generalizable to non-Chinese contexts. Practical implications The results may help organizational leaders develop a deeper understanding of the significance and the crux of inclusion. To address the duality of workforce diversity, managers can take initiatives to create an inclusive organization. To achieve inclusion, managers should pay attention to ways of improving the perceptions of inclusion among all employees. Originality/value This is among the first studies to identify the variants in inclusion in China using LPA. It reveals the subtypes and characteristics of inclusion and can serve as a starting point to explore how to realize organizational inclusion in theory and practice.

Using Methods from Personality Psychology to Study Post-Traumatic Growth

This chapter discusses methodological approaches for examining the causality, accuracy, stability, and mechanisms of short-term adversity-driven change in samples drawn from different populations, each highly likely to be exposed to different forms of challenge and failure. This methodological work builds on Frazier et al.’s (2009) groundbreaking longitudinal study. The authors discuss the advantages of using longitudinal multimethod measurement burst designs and a profile approach utilizing a round-robin design, as well as a qualitative assessment. Each methodology promises to address novel questions concerning the perception, meta-perception, and development of character following challenge and failure. The chapter also examines individual difference factors, such as social support and cumulative life adversity, which may moderate this relationship. Given that participants from different populations likely differ in the amount of cumulative adversity they have experienced, the authors also examine the possibilities and limitations of lifetime adversity in acting as a catalyst for subsequent growth.
