Political Decisions

This chapter explores the politics of identity in the Sicilian theater of the Peloponnesian War. Initially, most poleis in Sicily formed alliances based on ethnicity (either Dorian or Ionian), a form of kinship diplomacy that was typical in Greek politics. Camarina, however, allied with the Ionians despite being Dorian due to its unique polis identity, which had been shaped by hostility toward its mother city, Syracuse. Political decisions were thus conditioned by identities, and these, in turn, were often shaped by political rhetoric. An analysis of two speeches of the Syracusan politician Hermocrates, as rewritten by Thucydides, reveals a series of arguments, based on different identities in different contexts, that persuaded poleis to follow his recommendations. Identity thus played a central role in Greek politics, since the changing salience of different identities enabled poleis to make decisions on the basis of multiple identities over a short time.

Pre Service Teacher

The globalization of English has undoubtedly brought shifts into how the English language is taught in classroom settings and how English teachers are prepared. In English as a foreign language (EFL) settings, for example, teaching and learning English is generally influenced by local contexts. Taking into account the sociocultural contexts of the learners and the teachers, identity construction becomes one important aspect in the process of English teaching and learning. Focusing on the microanalysis of social language uses, the study was aimed to understand how pre-service teachers of English as a foreign language in a multilingual setting, Indonesia, enact their identities through their language use in classroom settings. The data for this study was obtained from a classroom observation where an English pre-service teacher was performing peer teaching. The discourse analysis of the first thirteen minutes of a pre-service teacher's teaching demonstration indicates that multiple identities were enacted when the student teacher switched from one language to another. The pervasive use of code-switching in four different languages (Indonesian, English, Arabic, and Malay) provides clues that Mamas, a student teacher's pseudonym in the study was enacting different identities as he taught his peers. While further research is absolutely necessary to obtain more vivid pictures of the reasons behind using multiple languages in teaching English within this context, the study provides insight about how pre-service teachers in an Indonesian context try to develop identities as they learn to teach English.

AbstractThe continuing debate in Bangladesh over the national identity of its people — whether one is a Bangali or Bangladeshi — is a post-1975 phenomenon. One of the main themes of the independence war (1971) was 'Bangali nationalism'. However, it was replaced with 'Bangladeshi nationalism' by a military government following a bloody military coup in 1975. This major change in the label of the national identity of the people of Bangladesh requires explanation. A sharp distinction in the nature of politics in Bangladesh between the pre- and post-1975 era offers an explanation of the politics of identity in Bangladesh. This study shows that the manifestations of these political identities have been represented discursively, according to the political ideologies adopted by the successive regimes in Bangladesh. This paper studies the material representations of national identity, specifically the discursive construction of national identity in Bangladesh. It investigates also whether national identity discourse is a creation of the political rhetoric during different eras or it is "over-determined" in Althusserian terms. In other words, this paper questions the ontological basis of national identity in Bangladesh.

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

AbstractReplication failures were among the triggers of a reform movement which, in a very short time, has been enormously useful in raising standards and improving methods. As a result, the massive multilab multi-experiment replication projects have served their purpose and will die out. We describe other types of replications – both friendly and adversarial – that should continue to be beneficial.

AbstractWe present an analysis of short time-scale intensity variations in the coronal green line as obtained with high time resolution observations. The observed data can be divided into two groups. The first one shows periodic intensity variations with a period of 5 min. the second one does not show any significant intensity variations. We studied the relation between regions of coronal intensity oscillations and the shape of white-light coronal structures. We found that the coronal green-line oscillations occur mainly in regions where open white-light coronal structures are located.

We have studied the destruction of rabbit muscle actin filaments by osmium tetroxide (OSO4) to develop methods which will preserve the structure of actin filaments during preparation for transmission electron microscopy.Negatively stained F-actin, which appears as smooth, gently curved filaments in control samples (Fig. 1a), acquire an angular, distorted profile and break into progressively shorter pieces after exposure to OSO4 (Fig. 1b,c). We followed the time course of the reaction with viscometry since it is a simple, quantitative method to assess filament integrity. The difference in rates of decay in viscosity of polymerized actin solutions after the addition of four concentrations of OSO4 is illustrated in Fig. 2. Viscometry indicated that the rate of actin filament destruction is also dependent upon temperature, buffer type, buffer concentration, and pH, and requires the continued presence of OSO4. The conditions most favorable to filament preservation are fixation in a low concentration of OSO4 for a short time at 0°C in 100mM sodium phosphate buffer, pH 6.0.

Intermediate high temperature tempering prior to subsequent reaustenitization has been shown to double the plane strain fracture toughness as compared to conventionally heat treated UHSLA steels, at similar yield strength levels. The precipitation (during tempering) of metal carbides and their subsequent partial redissolution and refinement (during reaustenitization), in addition to the reduction in the prior austenite grain size during the cycling operation have all been suggested to contribute to the observed improvement in the mechanical properties. In this investigation, 300M steel was initially austenitized at 1143°K and then subjected to intermediate tempering at 923°K for 1 hr. before reaustenitizing at 1123°K for a short time and final tempering at 583°K. The changes in the microstructure responsible for the improvement in the properties have been studied and compared with conventionally heat treated steel. Fig. 1 shows interlath films of retained austenite produced during conventionally heat treatment.

Short Time

Strong solid state bonds are routinely produced between physical vapor deposited (PVD) silver coatings deposited on sputter cleaned surfaces of two dissimilar metal parts. The low temperature (200°C) and short time (10 min) used in the bonding cycle are advantageous from the standpoint of productivity and dimensional control. These conditions unfortunately produce no microstructural changes at or near the interface that are detectable by optical, SEM, or microprobe examination. Microstructural problems arising at these interfaces could therefore easily go undetected by these techniques. TEM analysis has not been previously applied to this problem because of the difficulty in specimen preparation. The purpose of this paper is to describe our technique for preparing specimens from solid state bonds and to present our initial observations of the microstructural details of such bonds.

Highly polyploid somatic nucleus (macronucleus) of ciliate Bursaria truncatella under goes severe changes in morphology during cell division. At first, macronucleus (Ma) condences, diminishes in size and turns perpendicular to longitudinal axis of the cell. After short time, Ma turns again, elongates and only afterwards the process of division itself occurs. The biological meaning of these phenomena is not clear.Localization of RNA in the cells was performed on sections of ciliates B. truncatella, embedded in “Lowicryl K4M” at various stages: (1) before cell division (Figs. 2,3); (11) at the stage of macronucleus condensation; (111) during elongation of Ma (Fig.4); (1111) in young cells (0-5min. after division). For cytochemical labelling we used RNaseAcolloidal gold complexes (RNase-Au), which are known to bind to RNA containing cell ularstructures with high specificity. The influence of different parameters on the reliability and reproducibility of labelling was studied. In addition to the factors, discussed elsewhere, we found that the balance of mono- and bivalent cations is of great significance.
