Magnetic interactions in transition metal doped ZnO : An abinitio study
We calculate the nature of magnetic interactions in transition-metal doped
ZnO using the local spin density approximation and LSDA+\textit{U} method of
density functional theory. We investigate the following four cases: (i) single
transition metal ion types (Cr, Mn, Fe, Co, Ni and Cu) substituted at Zn sites,
(ii) substitutional magnetic transition metal ions combined with additional Cu
and Li dopants, (iii) substitutional magnetic transition metal ions combined
with oxygen vacancies and (iv) pairs of magnetic ion types (Co and Fe, Co and
Mn, etc.). Extensive convergence tests indicate that the calculated magnetic
ground state is unusually sensitive to the k-point mesh and energy cut-off, the
details of the geometry optimizations and the choice of the
exchange-correlation functional. We find that ferromagnetic coupling is
sometimes favorable for single type substitutional transition metal ions within
the local spin density approximation. However, the nature of magnetic
interactions changes when correlations on the transition-metal ion are treated
within the more realistic LSDA + \textit{U} method, often disfavoring the
ferromagnetic state. The magnetic configuration is sensitive to the detailed
arrangement of the ions and the amount of lattice relaxation, except in the
case of oxygen vacancies when an antiferromagnetic state is always favored.Comment: 11 pages, 17 figure
The Eyes Have It: Sex and Sexual Orientation Differences in Pupil Dilation Patterns
Recent research suggests profound sex and sexual orientation differences in sexual response. These results, however, are based on measures of genital arousal, which have potential limitations such as volunteer bias and differential measures for the sexes. The present study introduces a measure less affected by these limitations. We assessed the pupil dilation of 325 men and women of various sexual orientations to male and female erotic stimuli. Results supported hypotheses. In general, self-reported sexual orientation corresponded with pupil dilation to men and women. Among men, substantial dilation to both sexes was most common in bisexual-identified men. In contrast, among women, substantial dilation to both sexes was most common in heterosexual-identified women. Possible reasons for these differences are discussed. Because the measure of pupil dilation is less invasive than previous measures of sexual response, it allows for studying diverse age and cultural populations, usually not included in sexuality research
“It Was Easier in Prison!” : Russian Baptist Rehab as a Therapeutic Community, Monastery, Prison, and Ministry
This chapter revisits a Foucauldian concept of “complete and austere institutions,” using the ethnographic study of therapeutic communities, monasteries, prisons, and religious ministries to draw a line between those concepts, specifically addressing a Christian ministry in the Russian Baptist interpretation. My argument is based on an ethnographic account of the Russian Baptist ministry for people suffering from addiction. I unfold the concept of an Evangelical ministry, contrasting it to the Foucauldian austere institutions in order to highlight its nature. I argue that even though a rehabilitation ministry may use methods and techniques of austere institutions, and even resemble them in their implementation, the distinctive feature of a ministry is its focus on the result, rather than the process, interpreted as serving God by serving men.Peer reviewe
Protestant women in the late Soviet era: gender, authority, and dissent
At the peak of the anti-religious campaigns under Nikita Khrushchev,
communist propaganda depicted women believers as either naïve
dupes, tricked by the clergy, or as depraved fanatics; the Protestant
“sektantka” (female sectarian) was a particularly prominent folk-devil.
In fact, as this article shows, women’s position within Protestant
communities was far more complex than either of these mythical
figures would have one believe. The authors explore four important,
but contested, female roles: women as leaders of worship, particularly
in remote congregations where female believers vastly outnumbered
their male counterparts; women as unofficial prophetesses,
primarily within Pentecostal groups; women as mothers, replenishing
congregations through high birth rates and commitment to their
children’s religious upbringing; and women as political actors in the
defence of religious rights. Using a wide range of sources, which
include reports written by state officials, articles in the church journal,
letters from church members to their ecclesiastical leaders in
Moscow, samizdat texts, and oral history accounts, the authors
probe women’s relationship with authority, in terms of both the
authority of the (male) ministry within the church, and the authority
of the Soviet state
Conceptions of learning factors in postgraduate health sciences master students: a comparative study with nonhealth science students and between genders
Background: The students’ conceptions of learning in postgraduate health science master studies are poorly
understood. The aim of this study was to compare the factors influencing conceptions of learning in health
sciences and non-health sciences students enrolled in postgraduate master programs in order to obtain
information that may be useful for students and for future postgraduate programs.
Methods: A modified version of the Learning Inventory Conception Questionnaire (COLI) was used to compare
students’ conception learning factors in 131 students at the beginning of their postgraduate studies in health
sciences, experimental sciences, arts and humanities and social sciences.
Results: The present study demonstrates that a set of factors may influence conception of learning of health
sciences postgraduate students, with learning as gaining information, remembering, using, and understanding
information, awareness of duty and social commitment being the most relevant. For these students, learning as a
personal change, a process not bound by time or place or even as acquisition of professional competences, are less
relevant. According to our results, this profile is not affected by gender differences.
Conclusions: Our results show that the overall conceptions of learning differ among students of health sciences
and non-health sciences (experimental sciences, arts and humanities and social sciences) master postgraduate
programs. These finding are potentially useful to foster the learning process of HS students, because if they are
metacognitively aware of their own conception or learning, they will be much better equipped to self-regulate
their learning behavior in a postgraduate master program in health sciences.Supported by CTS-115 (Tissue Engineering Group of the University of Granada).

A faithful compass: rethinking the term restorative justice to find clarity
In the field of restorative justice (rj) there is regular debate regarding the terms restorative and justice. In spite of efforts to come to a common vision, this ongoing
discussion illustrates how theoretical and practical disagreements have resulted in rj being characterized as ambiguous and inconsistent within the judicial context and beyond (Gavrielides, 2008; Sullivan & Tifft, 2005; Johnstone & Van Ness, 2007). Arising out of research conducted in an education context (Vaandering, 2009), this paper identifies the impact of this ambiguity on educators. More importantly, however, it examines the term justice and discovers that an overemphasis on justice as fairness and individual rights has pulled the field off-course. The paper identifies that what is needed is a broader understanding of justice than that given in the judicial context and makes the case for justice as honouring the inherent worth of all and enacted through relationship. If understood as such, I argue that the terms restorative and justice must remain paired and in place in order to serve as a muchneeded
compass needle that guides proponents of rj in the field to their desired destinations
