Growing up in Affiliation with a Religious Community : A Case Study of Seventh-day Adventist Youth in Finland

This study investigates how the religious community as a socialization context affects the development of young people's religious identity and values, using Finnish Seventh-day Adventism as a context for the case study. The research problem is investigated through the following questions: (1) What aspects support the intergenerational transmission of values and tradition in religious home education? (2) What is the role of social capital and the social networks of the religious community in the religious socialization process? (3) How does the religious composition of the peer group at school (e.g., a denominational school in comparison to a mainstream school) affect these young people s social relations and choices and their religious identity (as challenged versus as reinforced by values at school)? And (4) How do the young people studied negotiate their religious values and religious membership in the diverse social contexts of the society at large? The mixed method study includes both quantitative and qualitative data sets (3 surveys: n=106 young adults, n=100 teenagers, n=55 parents; 2 sets of interviews: n=10 young adults and n=10 teenagers; and fieldwork data from youth summer camps). The results indicate that, in religious home education, the relationship between parents and children, the parental example of a personally meaningful way of life, and encouraging critical thinking in order for young people to make personalized value choices were important factors in socialization. Overall, positive experiences of the religion and the religious community were crucial in providing direction for later choices of values and affiliations. Education that was experienced as either too severe or too permissive was not regarded as a positive influence for accepting similar values and lifestyle choices to those of the parents. Furthermore, the religious community had an important influence on these young people s religious socialization in terms of the commitment to denominational values and lifestyle and in providing them with religious identity and rooting them in the social network of the denomination. The network of the religious community generated important social resources, or social capital, for both the youth and their families, involving both tangible and intangible benefits, and bridging and bonding effects. However, the study also illustrates the sometimes difficult negotiations the youth face in navigating between differentiation and belonging when there is a tension between the values of a minority group and the larger society, and one wants to and does belong to both. It also demonstrates the variety within both the majority and the minority communities in society, as well as the many different ways one can find a personally meaningful way of being an Adventist. In the light of the previous literature about socialization-in-context in an increasingly pluralistic society, the findings were examined at four levels: individual, family, community and societal. These were seen as both a nested structure and as constructing a funnel in which each broader level directs the influences that reach the narrower ones. The societal setting directs the position and operation of religious communities, families and individuals, and the influences that reach the developing children and young people are in many ways directed by societal, communal and family characteristics. These levels are by nature constantly changing, as well as being constructed of different parts, like the pieces of a jigsaw puzzle, each of which alters in significance: for some negotiations on values and memberships the parental influence may be greater, whereas for others the peer group influences are. Although agency does remain somewhat connected to others, the growing youth are gradually able to take more responsibility for their own choices and their agency plays a crucial role in the process of choosing values and group memberships.

Bear Shields of Plains Indians : Motifs and Meanings

The study is the outcome of two research projects on the North American Indian traditions: the role of the shields within the Plains Indians traditional culture and religion, and the bear ceremonialism of the Native North America, especially the significance of the bear among the Plains Indians. This article-based dissertation includes seven separately published scholar papers, forming Chapters 6 12. The introduction formulates the objectives and frame of reference of the study and the conclusions pulls together its results. The study reconsiders the role of the Plains Indian shields with bear motifs. Such shields are found in rock art, in the Plains Indian s paintings and drawings, and in various collections, the main source material being the shields in European and North American museums. The aim is not only to study shields with bear power motifs and the meanings of the bear, but also to discuss appropriate methods for studying these subjects. There are three major aims of the study: to consider methodical questions in studying Plains Indian shields, to examine the complexity of the Plains Indian shields with the bear power motifs, and to offer new interpretations for the basic meanings of the bear among the Plains Indians and the interrelationship between individualism and collectivism in the Plains Indians visionary art that show bear power motifs on the shields. The study constructs a view on the bear shields taking account of all sources of information available and analysing the shields both as physical artefacts and religious objects from different perspectives, studying them as a part of the ensemble of Plains culture and religious traditions. The bear motifs represented the superhuman power that medicine men and warriors could exploit through visions. For the Plains Indians, the bear was a wise animal from which medicine men could get power for healing but also a dangerous animal from which warriors could get power for warfare. The shields with bear motifs represented the bear powers of the owners of the shields. The bear shield was made to represent the vision, and the principal interpretation of the symbolism was based on the individual experience of spiritual world and its powers. The study argues that the bear shield as personal medicine object is based on wider tribal traditions, and the basic meaning is derived from the collective tradition. This means that the bear seen in vision represented particular affairs and it was represented on the shield surface using conventional ways of traditional artistry. In consequence of this, the bear shields reflect not only the individual experiences of bear power but whole field of tribal traditions that legitimated the experiences and offered acceptable interpretations and conventional modes for the bear symbols.

Repulsive fermions in optical lattices: Phase separation versus coexistence of antiferromagnetism and d-wave superfluidity

We investigate a system of fermions on a two-dimensional optical square lattice in the strongly repulsive coupling regime. In this case, the interactions can be controlled by laser intensity as well as by Feshbach resonance. We compare the energetics of states with resonating valence bond d-wave superfluidity, antiferromagnetic long-range order, and a homogeneous state with coexistence of superfluidity and antiferromagnetism. Using a variational formalism, we show that the energy density of a hole e(hole)(x) has a minimum at doping x = x(c) that signals phase separation between the antiferromagnetic and d-wave paired superfluid phases. The energy of the phase-separated ground state is, however, found to be very close to that of a homogeneous state with coexisting antiferromagnetic and superfluid orders. We explore the dependence of the energy on the interaction strength and on the three-site hopping terms and compare with the nearest-neighbor hopping t-J model.

Joint evaluation of channel feedback schemes, rate adaptation, and scheduling in OFDMA downlinks with feedback delays

Orthogonal frequency-division multiple access (OFDMA) systems divide the available bandwidth into orthogonal subchannels and exploit multiuser diversity and frequency selectivity to achieve high spectral efficiencies. However, they require a significant amount of channel state feedback for scheduling and rate adaptation and are sensitive to feedback delays. We develop a comprehensive analysis for OFDMA system throughput in the presence of feedback delays as a function of the feedback scheme, frequency-domain scheduler, and rate adaptation rule. Also derived are expressions for the outage probability, which captures the inability of a subchannel to successfully carry data due to the feedback scheme or feedback delays. Our model encompasses the popular best-n and threshold-based feedback schemes and the greedy, proportional fair, and round-robin schedulers that cover a wide range of throughput versus fairness tradeoff. It helps quantify the different robustness of the schedulers to feedback overhead and delays. Even at low vehicular speeds, it shows that small feedback delays markedly degrade the throughput and increase the outage probability. Further, given the feedback delay, the throughput degradation depends primarily on the feedback overhead and not on the feedback scheme itself. We also show how to optimize the rate adaptation thresholds as a function of feedback delay.

Training for Antenna Selection in Time-Varying Channels: Optimal Selection, Energy Allocation, and Energy Efficiency Evaluation

Single receive antenna selection (AS) is a popular method for obtaining diversity benefits without the additional costs of multiple radio receiver chains. Since only one antenna receives at any time, the transmitter sends a pilot multiple times to enable the receiver to estimate the channel gains of its N antennas to the transmitter and select an antenna. In time-varying channels, the channel estimates of different antennas are outdated to different extents. We analyze the symbol error probability (SEP) in time-varying channels of the N-pilot and (N+1)-pilot AS training schemes. In the former, the transmitter sends one pilot for each receive antenna. In the latter, the transmitter sends one additional pilot that helps sample the channel fading process of the selected antenna twice. We present several new results about the SEP, optimal energy allocation across pilots and data, and optimal selection rule in time-varying channels for the two schemes. We show that due to the unique nature of AS, the (N+1)-pilot scheme, despite its longer training duration, is much more energy-efficient than the conventional N-pilot scheme. An extension to a practical scenario where all data symbols of a packet are received by the same antenna is also investigated.

Biodiversity and ecological assessments of Indian sacred groves

Sacred groves are patches of forests preserved for their spiritual and religious significance. The practice gained relevance with the spread of agriculture that caused large-scale deforestation affecting biodiversity and watersheds. Sacred groves may lose their prominence nowadays, but are still relevant in Indian rural landscapes inhabited by traditional communities. The recent rise of interest in this tradition encouraged scientific study that despite its pan-Indian distribution, focused on India's northeast, Western Ghats and east coast either for their global/regional importance or unique ecosystems. Most studies focused on flora, mainly angiosperms, and the faunal studies concentrated on vertebrates while lower life forms were grossly neglected. Studies on ecosystem functioning are few although observations are available. Most studies attributed watershed protection values to sacred groves but hardly highlighted hydrological process or water yield in comparison with other land use types. The grove studies require diversification from a stereotyped path and must move towards creating credible scientific foundations for conservation. Documentation should continue in unexplored areas but more work is needed on basic ecological functions and ecosystem dynamics to strengthen planning for scientifically sound sacred grove management.

Discrete-Rate Adaptation and Selection in Energy Harvesting Wireless Systems

In a system with energy harvesting (EH) nodes, the design focus shifts from minimizing energy consumption by infrequently transmitting less information to making the best use of available energy to efficiently deliver data while adhering to the fundamental energy neutrality constraint. We address the problem of maximizing the throughput of a system consisting of rate-adaptive EH nodes that transmit to a destination. Unlike related literature, we focus on the practically important discrete-rate adaptation model. First, for a single EH node, we propose a discrete-rate adaptation rule and prove its optimality for a general class of stationary and ergodic EH and fading processes. We then study a general system with multiple EH nodes in which one is opportunistically selected to transmit. We first derive a novel and throughput-optimal joint selection and rate adaptation rule (TOJSRA) when the nodes are subject to a weaker average power constraint. We then propose a novel rule for a multi-EH node system that is based on TOJSRA, and we prove its optimality for stationary and ergodic EH and fading processes. We also model the various energy overheads of the EH nodes and characterize their effect on the adaptation policy and the system throughput.

Temperature-Dependent Magnetic and EPR Studies of Bulk and Nanoparticles of Bi0.1Ca0.9MnO3

We report temperature-dependent magnetic and electron paramagnetic resonance (EPR) properties of bulk and nanoparticle samples of Bi0.1Ca0.9MnO3 (BCMO). The nanoparticles of BCMO (dia similar to 50 nm) were prepared by the standard sol-gel technique and bulk samples by solid-state reaction method. We have investigated the magnetic ordering in the two samples by carrying out temperature-dependent magnetic and EPR studies and compared their properties. According to earlier reports, antiferromagnetic and ferromagnetic orders coexist in the bulk sample of Bi0.1Ca0.9MnO3. Our magnetization and EPR results show the existence of ferromagnetism in the bulk sample which is present in the nanosample as well but with somewhat weakened strength with the size reduction.

Interactions between reflection and praxis in the history of economic thought : the case of the franciscan circles from XIII century Assisi to the present

Resumen: Daniela Parisi analiza el impacto de la vida de San F rancisco de Asís desde la perspectiva de la historia del pensamiento económico. Haciendo referencia particularmente a la atención otorgada en los círculos franciscanos a los signos de los tiempos, la autora traza el camino desde la vida de San Francisco, pasando por la vida de la Orden hasta el presente, y revela los orígenes del movimiento franciscano como un intento de reforma social y religiosa. En primer lugar, el artículo presenta la vida que llevó San Francisco como una “pobreza material voluntaria” en el contexto de los cambios socio-económicos que tuvieron lugar en el siglo XIII, con el advenimiento de la sociedad comercial. Luego, explica cómo la propuesta de San Francisco creció hasta convertirse en una orden religiosa. Finalmente, el artículo intenta iluminar aquellos aspectos en que la Orden Franciscana puede todavía considerarse un signo de los tiempos a través de una existencia comprometida con la pobreza, eliminando lo superfluo de nuestra vida y viviendo en consonancia con el Evangelio.

Sobre el embrión humano y la cuestión de la personeidad : un argumento de Luigi Ferrajoli y su discusión

Resumen: El texto analiza las afirmaciones defendidas sobre el estatuto entitativo del embrión y de la solución ética a la cuestión de la legitimidad del aborto provocado, en un trabajo del jurista y pensador italiano, Luigi Ferrajoli, defensor de lo que puede denominarse el bioderecho “liberal”, con una posición decisivamente tomada en favor de la eticidad del aborto. Se advierte que cada uno de sus argumentos parte de una premisa: considerar las afirmaciones de la Iglesia Católica como inexorablemente erróneas, especialmente en lo atinente a la relación entre moral y derecho. La consecuencia más grave de este tipo de argumentación es la deriva anti-humanista del pensamiento contemporáneo con la consiguiente pérdida de toda racionalidad lógica.

Rafael Pividal y Alberto Duhau : aportes y debates en torno a la idea de democracia en el pensamiento político de intelectuales católicos

Resumen: A finales de la década del treinta, especialmente luego de la visita de Maritain en 1936 a la Argentina, surgieron con mucha fuerza una serie de debates dentro de los círculos intelectuales católicos argentinos. Uno de los temas tratados, entre otros, fue el valor de la democracia y, especialmente, su posible justificación como sistema político y su concordancia con las enseñanzas de la Iglesia. Sin embargo, aun aquellos que defendían la democracia no representaban un grupo homogéneo: tanto las fuentes intelectuales a las que recurrían como los fundamentos antropológicos de sus argumentaciones eran diversas. El presente artículo se propone desarrollar la defensa de la democracia que hicieron R. Pividal y A. Duhau, dos de estos intelectuales católicos. Como intentaré demostrar, aun cuando coinciden en resaltar el valor de la democracia y su plena concordancia con el catolicismo, la recurrencia a autores diversos (Maritain y a través de él la oposición a Maurras y Rousseau en un caso y Adam Smith y el Liberalismo escocés en el otro) generan que las argumentaciones de uno y otro difícilmente coincidan en mucho más que en esa positiva valoración que hacen del sistema democrático.

La política en la actualidad : ¿más cerca de la virtud o del vicio?

Resumen: En este artículo se expone en forma sucinta dos formas muy diferentes de concebir la política, a saber: la de algunos autores denominados clásicos, cuyos principales representantes son Platón, Aristóteles, Cicerón y Tomás de Aquino, y la forma moderna representada por Maquiavelo. Los primeros, salvando algunas diferencias, entienden la política como un saber moral práctico, como una noble actividad que debe ser ejercida por los mejores en vistas al bien de todos. Maquiavelo, por su parte, la entiende como una técnica, totalmente desarraigada de la moral, cuyo fin es obtener, mantener y acrecentar el poder. Al parecer, y es lo que se intentará demostrar en la exposición, hay indicios suficientes para afirmar que el maquiavelismo se ha «impuesto» a los clásicos. La perspectiva desde la cual se abordara esta pregunta, es la del Magisterio reciente de la Iglesia Católica
