Motivational profiles and their relationships with basic psychological needs, academic performance, study strategies, self-esteem, and vitality in dental students in Chile

Purpose To determine dental students’ motivational profiles through a person-centred approach and to analyse the associations with the satisfaction of their basic psychological needs, study strategies, academic performance, self-esteem, and vitality. Methods A total of 924 students from the University of San Sebastian (Chile) participated in this cross-sectional cor¬relational study in spring 2016. Data were collected through 5 self-reported instruments, in addition to students’ academic performance. The Cronbach alpha, descriptive statistics, and correla¬tion scores were computed. A k-means cluster analysis with intrinsic and controlled motivation was conducted to identify different mo-tivational profiles. Subsequently, multivariate analysis of covariance controlling for the effects of gender and year of study was carried out to assess differences among the retained motivational profiles and learning variables. Results All instruments showed acceptable Cronbach alpha scores. A 4-cluster solution was retained for the motivational profile over a 3- or 5-cluster solution. Students’ motiva-tional profiles were characterized by different degrees of intrinsic and controlled motivation. The high intrinsic motivation groups showed higher perceptions of their basic psychological, a greater propensity for a deep rather than surface study strategy, better academic performance, and higher scores for self-esteem and vitality than the low intrinsic motivation groups, regardless of the degree of controlled motivation. Conclusion Students with a high intrinsic motivation profile, regardless of their controlled motivation scores, reported better learning characteristics. Therefore, special attention should be paid to students’ motivational profiles, as the quality of motivation might serve as a basis for interventions to support their academic success and well-being

A Day among the Diehard terrorists: the psychological costs of doing ethnographic research

This article describes the experience of a sociologist who made contact with a group of diehard terrorists responsible for multiple murders in order to conduct an ethnographic study. After outlining the sociological profile of the diehard terrorists, the author—making reference to the ethnographic studies of Jack Douglas, Martin Sanchez Jankowski, and Laud Humphreys—describes how he followed their traces. The aim of the article is to analyze the psychological costs that the sociologist must pay when he interacts with men and women who, in addition to proudly claiming credit for the homicides they have committed, affirm the importance of continuing to kill in order to salvage humanity’s future

Motivation as a predictor of dental students’ affective and behavioral outcomes: Does the quality of motivation matter?

Since the motivation to study and engage in academic activities plays a key role in students’ learning experience and well-being, gaining a better understanding of dental students’ motivations can help educators implement interventions to support students’ optimal motivations. The aim of this study, grounded in self-determination theory, was to determine the predictive role of different types of motivation (autonomous motivation, controlled motivation, and amotivation) in the affective and behavioral outcomes of dental students. Amotivation is the absence of drive to pursue an activity due to a failure to establish relationships between activity and behavior; controlled motivation involves behaving under external pressure or demands; and autonomous motivation is an internalized behavior with a full sense of volition, interest, choice, and self-determination. A cross-sectional correlational study was conducted in 2016, in which 924 students (90.2% response rate) from years one to six agreed to participate, granting permission to access their current GPAs and completing four self-reported questionnaires on academic motivation, study strategies, vitality, and self-esteem. The results showed that self-determined motivation (i.e., autonomous over controlled motivation) was positively associated with vitality, self-esteem, and deep study strategies and negatively associated with surface study strategies. The contrary results were found for amotivation. In the motivational model, deep study strategies showed a positive association with students’ academic performance. Contrary results were found for surface study strategies. This study extends understanding of the differentiation of motivation based on its quality types and suggests that being motivated does not necessarily lead to positive educational outcomes. Autonomous motivation, in contrast to controlled motivation and amotivation, should be supported to benefit students with regard to their approaches to learning and well-being since it can promote students’ vitality, self-esteem, deep over surface study strategies, and enhanced academic performance

Colloidal Assemblies of Oriented Maghemite Nanocrystals and their NMR Relaxometric Properties

Elevated-temperature polyol-based colloidal-chemistry approach allows for the development of size-tunable (50 and 86 nm) assemblies of maghemite iso-oriented nanocrystals, with enhanced magnetization. 1H-Nuclear Magnetic Resonance (NMR) relaxometric experiments show that the ferrimagnetic cluster-like colloidal entities exhibit a remarkable enhancement (4 to 5 times) in the transverse relaxivity, if compared to that of the superparamagnetic contrast agent Endorem, over an extended frequency range (1-60 MHz). The marked increase of the transverse relaxivity r2 at a clinical magnetic field strength (1.41 T), which is 405.1 and 508.3 mM-1 s-1 for small and large assemblies respectively, allows to relate the observed response to the raised intra-aggregate magnetic material volume fraction. Furthermore, cell tests with murine fibroblast culture medium confirmed the cell viability in presence of the clusters. We discuss the NMR dispersion profiles on the basis of relaxivity models to highlight the magneto-structural characteristics of the materials for improved T2-weighted magnetic resonance images.Comment: Includes supporting informatio

Poverty, ideology and terrorism: the STAM Bond

This article focuses on the role of ideology in the decision of people who are not from societies’ worst-off socioeconomic groups to join a left-wing terrorist organization. Taking up the sociological perspective of Max Weber, Clifford Geertz, and Raymond Boudon, the author introduces the concept of the “terrorist of the first hour” and considers ideology as a type of social bond. The concept of ideology is here broken down into four dimensions: Social, Temporal, Affective, and Moral (STAM bond). This article also presents data on the ages, sex, educational level, and occupation of the Italian people arrested (2,730) or convicted (528) for crimes of terrorism from 1970 to 2011. Data on Italian terrorists were provided by the General Department of Prisoners of the Ministry of Justic

Interview with a terrorist by vocation: a day among the Diehard terrorists, Part 2.

The interview that follows was conducted somewhere in Italy with a militant of the Red Brigades recently freed after spending 32 years and 6 months in prison. Taking up the sociological perspective of Max Weber, the author draws a distinction between “professional terrorist” and “vocational terrorist”. The terrorist by vocation differs from the professional terrorist in his profound faith in the mission he feels he must accomplish. He does not try to improve his social status and is not interested in the selfish pursuit of personal well-being. He gives up love, family, children and friendship. When he decides to join a terrorist group, he voluntarily severs any contact with his former life. He is a high school or university graduate and might choose a secure life and a good job but prefers to kill, accepting the risk of dying. The vocational terrorist is the terrorist in his incandescent state

Las Brigadas Rojas y el poder de las ideologìas asesinas

This article analyses the case of the Italian Red Brigades as an example of extreme left terrorism of Marxist-Leninist inspiration. The analysis emphasizes the role of ideology as a mental framework that explains the action of terrorists and presents them as "terrorists by vocation." In other words, those, who having the possibility of leading a comfortable life, choose terrorist action to placate a "spiritual" need

Fish consumption in relation to myocardial infarction, stroke and mortality among women and men with type 2 diabetes: A prospective cohort study

\textit{Background & aims:} The accumulated evidence supports an inverse association of fish consumption with cardiovascular disease and mortality, but data among patients with type 2 diabetes are sparse. We aimed to assess fish consumption in relation to myocardial infarction (MI), stroke and mortality among individuals with type 2 diabetes. $\textit{Methods:}$ Women and men with diagnosed type 2 diabetes (n = 2225; aged 45-84 years) within two population-based cohorts (the Swedish Mammography Cohort and the Cohort of Swedish Men) were followed from 1998 through 2012. Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). $\textit{Results:}$ We identified 333 incident MI events, 321 incident stroke events and 771 deaths (154 with coronary heart disease [CHD] as underlying cause) during follow-up of up to 15 years. The multivariable HRs comparing >3 servings/week with $\leq$3 servings/month were 0.60 (95% CI, 0.39-0.92) for MI and 1.04 (95% CI, 0.66-1.64) for stroke. HRs for total mortality were lowest for moderate fish consumption of 1-<2 servings/week (0.82; 95% CI, 0.64-1.04) and 2-3 servings/week (0.79; 95% CI, 0.61-1.01) compared with $\leq$3 servings/month. The corresponding HRs for CHD-related mortality were 0.53; 95% CI, 0.32-0.90 and 0.75; 95% CI, 0.45-1.27. $\textit{Conclusions:}$ Fish consumption was associated with lower MI incidence among individuals with type 2 diabetes, whereas no association was observed with stroke. Our data further indicated an association with lower mortality, particularly for CHD-related deaths. These findings support the current general advice on regular fish consumption also in the high risk group of type 2 diabetes patients.This work was supported by research grants from the Swedish Research Council/Committee for Research Infrastructure, from the Karolinska Institutet's Award for PhD students (KID-funding).
