The present research study is an effort to evaluate the effect of different nanoparticles in lime-pozzolan system, in time. nanosilica, nanoalumina and nanocalcium oxide were used in different combinations in this traditional binding system. The paper aims to record the durability of the traditional binding system in time, up to 365 days. For that purpose, the samples were subjected to ageing tests, such as wetting-drying cycles, sea water cycles and salt cycles. Up to 90 days, nanosilica benefits the most of the physic-mechanical properties, as well as the microstructure. Though, by studying the systems in time, the behavior of the other nanoparticles seems to favor certain properties more than nanosilica, especially at later ages. The addition of nanocalcium oxide combined with nanoalumina aids the improvement of the microstructure and the system presented great compressive after 40 cycles in ageing tests.

Tv Broadcasting

This paper has two purposes: one conceptual and the other practical. On a conceptual level, it outlines a model for understanding how TV operates as a social mediator in the event of natural disasters, and at the practical level, it recommends measures that can be used to optimize the role of TV and its ideal social function in contexts of crisis. This model views TV intervention as both «self-centered», that is, driven by its reproduction as a media consumption company; and «socially-centered», designed to respond swiftly and accurately to the social requirements that emerge in crisis situations. The suggested model is to be contrasted with the results of a research study conducted by the National TV Council of Chile that explored the role of TV broadcasting after the earthquake in February 2010. According to the results of the study, audiences value the amount of information broadcasted by TV networks but perceive that the predominance of its «self-centered» function creates a problem: the logic of the 'spectacle' is prevalent and exacerbates the audience’s emotions. The primary purpose of this paper is to develop a strategy to recommend how TV and its associate services can respond to a crisis situation while respecting the tragedy of natural disasters.Este trabajo contempla a la vez un propósito conceptual y otro de orden práctico. En lo conceptual se propone un modelo para comprender el funcionamiento de la televisión en escenarios de catástrofe y consecutivamente se sugiere, desde este modelo, un conjunto de derivaciones prácticas destinadas a optimizar la funcionalidad de la televisión en estos escenarios. El modelo propuesto concibe la intervención televisiva con una doble funcionalidad, una de carácter «autocéntrico» focalizada en su reproducción como empresa y otra de carácter «sociocéntrico» orientada a responder a los requerimientos surgidos en el escenario de la crisis. Este modelo será contrastado con los resultados de un estudio del Consejo Nacional de Televisión de Chile que indagó sobre el rol que asumió la televisión en el terremoto acaecido en Chile el año 2010. Según este estudio, si bien se valora el rol informativo y orientador de la televisión, la doble funcionalidad de su intervención fue percibida como problemática, con predominio de la funcionalidad autocéntrica que, desde una lógica de la espectacularidad, buscó construir audiencias, empleando una estrategia basada en la hiperactivación emocional. Finalmente, se concluye con una propuesta para conducir la televisión desde una intervención en la crisis hacia una efectiva intervención en crisis optimizando su funcionalidad sociocéntrica.

The purpose of this research study was to investigate the role of so-called English Medium schools in the teaching of English. In Pakistan, English is considered a gateway to success, a person having command on the language is offered a job while the other one having command on the subject matter is rejected, therefore it is a common trend in Pakistan that people belonging to all walks of life prefer to send their children to privately managed English medium schools. To measure the role schools in teaching English, both quantitative and qualitative approaches were adopted, and by using a purposive random sampling procedure one hundred and twenty heads of so-called English medium schools were selected. A questionnaire having close-ended and open-ended items were used to getting the opinions of schools’ heads regarding the role of school in teaching English. The quantitative responses were analyzed using SPSS while qualitative responses were sorted, labeled, and quantified. The data analysis reveals that privately managed schools are so-called English medium schools. They have neither qualified staff nor facilities which are required for the teaching of English.

Islam is a humanity based religion and unity plays of a vital role in it. It is not possible for a humane person to deny the importance of unity for a better society. It is the one thing that leads the nations of the world in the way of progress and prosperity. On the other hand chaos and anarchy is such a curse that makes a nation fall into the depths of disgrace. No enemy needs to fight such nation to defeat it. Their own internal conflicts and chaos is enough to dismantle them. Unfortunately this egoism and prejudice has reached its climax among the Muslims of Pakistan. We have failed ourselves in building a balanced progressive and welfare society based on two nation theory. Witnessing this situation many scholars from different schools of thoughts have tried their best towards the progress of inter-Muslim harmony and tolerance. In this regard they have highlighted the evil effects of chaos and positivity of unity. They have also brought forward such advises both in speech and written through which damage caused by sectarianism can be handled.

The studies on the micro-hardness of ChGs provide useful information regarding their straightforward involvement in the fabrication of sensors, fibers, and other optical elements for direct use in infrared optics. This work deals with the mechanical response of the glassy Se90In10 alloy under the influence of additives (Sn, Ag, Sb, and Ge). For this, we have determined the micro-hardness of all glassy alloys. Using the values of Vickers hardness (Hv), glass transition temperature (Tg), and present glasses, we have calculated the other significant thermo-mechanical parameters. The effect of Sn, Ag, Sb, and Ge additives on the micro-hardness of glassy Se90In10 alloy is also discussed.

All teachers expect that any teaching and learning process achieve adequate results to its learners. To achieve such an adequate result, it is lucid that the role of the teachers is urgent and essential. Teachers are required to possess initiatives and creativities in exploring various models, strategies, and methods of teaching and learning. Another characteristic required from a teacher is the ability to read, comprehend, analyze, and apply appropriate models, strategies, and methods in every instructional activity. The present research study aims to explore one cooperative learning model named Numbered Head Together (NHT). This learning model is offered as an alternative learning model and expected to create comfortable instructional environment in order to assure maximum learning achievement for the students. The Numbered Head Together explored in this research study was conducted in four phases namely numbering, raising questions, thinking together, and answering the questions. The application of such a model of NHT, as indicated, could increase the learning achievement of the students investigated in this study.  In pre-cycle stage the percentage of the students complete the topic was only 13%, meaning that the other 87% was not complete. When such a model was applied, however, the significant increase was shown by the students. In Cycle 1 the average of the students complete the topic was 60.9%, indicating that only 39.1% was not complete.  In Cycle 2, the average of the complete students reached 91.3% and only 8.7% of the students were not complete. By the last cycle of the application of NHT model, the average peaked at 100%, indicating that all of the students were complete to finish the topic of the lesson. Based on the findings of the study, it is concluded that the application of Numbered Head Together (NHT) cooperative learning model is advantageous in increasing the learning achievement of the four graders at St. Maria Imaculata Catholic Primary School of Ende 8.

Underlying Pathology

This study is part of a larger research study (doctoral dissertation), in which a comparative study with adolescent samples is done: 50 anorexic restricting patients (ANP), 50 patients diagnosed with depression (DP) and 50 non patients (NP). The proposed objective is two-fold: 1) To try to clarify the existing relationship between Anorexia (AN) and Depression (D), investigated from diverse disciplines but without conclusive results. 2) To detect in the ANP personality different traits from those of other groups, which should, if possible, allow to detect them at an early stage for an adequate prognosis. The current article presents the Rorschach findings in relation to the cognitive functioning of the ANP. In them, the following has been detected: (1) An information processing similar to that of the other groups, even with a more complete (L ≤ .99), more complex (DQ+↑) and better discriminated (Zd↑) grasp of the stimulus; (2) Mediating processes very similar to those of the other groups, sharing with them the perceptive maladjustments (X–%↑) and an excessive individualism (Xu%↑); (3) A clearly differentiating ideation disorder. Definitely, the ANP use predominantly ideation (M↑), but their thought, usually well-adjusted (MQo↑), presents eventual operations of delusional type (MQnone↑). Above that, their thinking is marked by a great passivity (Mp↑), which makes them more vulnerable to accept ideas without criticizing them and it results in a very inefficient thinking, which spins around these concepts without finding solutions, entering into a sort of ruminating which is completely unproductive. The differences toward the obsessive pathology are established. The discriminant analysis conducted with all the Rorschach variables that resulted as significant throughout the research, provides quite a consistent function which discriminates the ANP: MQnone↑, Mp↑, FD↓, Ma↑, MQo↑, AdjD↑, Sum H↑, (H)↑. Based on this we can understand that these adolescents, being in a developmental period of big changes and disorientations in relation with their own image, confronted with life events, and possibly starting off with some biologic vulnerability: (1) Due to the alterations of their ideation, accept without criticism (Mp) irrational ideas dominating in our culture, in which slimness appears as the only model, synthesis of intelligence, beauty and success; remaining captured in this type of mental activity (MQnone), which they cannot escape nor criticize (Mp), despite they reason adequately on other topics (MQo); (2) Their alterations of self-perception [(H)] make them hide themselves in a fantasized image, which is the axis of their interests and the only thing that really matters to them; (3) The resources they have to decide on behaviors and to finish these deliberately (AdjD), and their scarce tendency to the introspection (FD) lead to their decision of not eating, based on distorted and passively accepted thinking, which has great power and thus, so difficult to modify. Finally, based on the Rorschach data obtained, the hypothesis of a personality disorder as underlying pathology is pointed out.

SummaryWe measured total and free protein S (PS), protein C (PC) and factor X (FX) in 393 healthy blood donors to assess differences in relation to sex, hormonal state and age. All measured proteins were lower in women as compared to men, as were levels in premenopausal women as compared to postmenopausal women. Multiple regression analysis showed that both age and subgroup (men, pre- and postmenopausal women) were of significance for the levels of total and free PS and PC, the subgroup effect being caused by the differences between the premenopausal women and the other groups. This indicates a role of sex-hormones, most likely estrogens, in the regulation of levels of pro- and anticoagulant factors under physiologic conditions. These differences should be taken into account in daily clinical practice and may necessitate different normal ranges for men, pre- and postmenopausal women.

In the XIV century. centripetal tendencies began to appear in the Moscow principality. Inside the Russian church, several areas were distinguished. Part of the clergy supported the specificobar form. The other understood the need for transformations in society. As a result, this led to a split in the Russian church in the 15th century for "non-possessors" and "Josephites". The former linked the fate of the future with the ideology of hesychasm and its moral transformation, while the latter sought support in alliance with a strong secular power.

This paper is a contribution to the growing literature on the role of projective identification in understanding couples' dynamics. Projective identification as a defence is well suited to couples, as intimate partners provide an ideal location to deposit unwanted parts of the self. This paper illustrates how projective identification functions differently depending on the psychological health of the couple. It elucidates how healthier couples use projective identification more as a form of communication, whereas disturbed couples are inclined to employ it to invade and control the other, as captured by Meltzer's concept of "intrusive identification". These different uses of projective identification affect couples' capacities to provide what Bion called "containment". In disturbed couples, partners serve as what Meltzer termed "claustrums" whereby projections are not contained, but imprisoned or entombed in the other. Applying the concept of claustrum helps illuminate common feelings these couples express, such as feeling suffocated, stifled, trapped, held hostage, or feeling as if the relationship is killing them. Finally, this paper presents treatment challenges in working with more disturbed couples.

Thomas More's “rule” of pleasure before, after, and inUtopia

After establishing a context of More's lifelong engagement with the “calculus” of pleasure, this essay shows how the section devoted to the Utopians' pleasure philosophy is structured around five formulations of a “rule” to calculate “true and honest [honesta]” pleasure in ways that playfully imitate and echo the “rule” Cicero formulates several times in De officiis to discern one's duty when there seems to be a conflict between honestas et utilitas. When followed, the Utopian pleasure calculus shows the necessary role of societas, officii, iustitia, caritas, and the other aspects of human nature, most importantly friendship, that Cicero stresses in his rule and that he argued Epicurus ignored. Much of the irony and humor of this section depends on seeing the predominance of Ciceronian vocabulary in Raphael's unusual defense [patrocinium] of pleasure, rather than a Ciceronian defense of duty rooted in honestas. Throughout, however, this essay also shows how More goes beyond Cicero by including Augustinian and biblical allusions to suggest ways that our final end is not as Epicurus or the Stoics or Cicero claim; the language and allusions of this section point to a level of good cheer and care for neighbors and for God in ways quite different from any classical thinker.
