Education paths for documentary distribution: DAF, ATOM and the study guides that bind them

An expanding education market targeted through ‘bridging material’ enabling cineliteracies has the potential to offer Australian producers with increased distribution opportunities, educators with targeted teaching aids and students with enhanced learning outcomes. For Australian documentary producers, the key to unlocking the potential of the education sector is engaging with its curriculum-based requirements at the earliest stages of pre-production. Two key mechanisms can lead to effective educational engagement; the established area of study guides produced in association with the Australian Teachers of Media (ATOM) and the emerging area of philanthropic funding coordinated by the Documentary Australia Foundation (DAF). DAF has acted as a key financial and cultural philanthropic bridge between individuals, foundations, corporations and the Australian documentary sector for over 14 years. DAF does not make or commission films but through management and receipt of grants and donations provides ‘expertise, information, guidance and resources to help each sector work together to achieve their goals’. The DAF application process also requires film-makers to detail their ‘Education and Outreach Strategy’ for each film with 582 films registered and 39 completed as of June 2014. These education strategies that can range from detailed to cursory efforts offer valuable insights into the Australian documentary sector's historical and current expectations of education as a receptive and dynamic audience for quality factual content. A recurring film-maker education strategy found in the DAF data is an engagement with ATOM to create a study guide for their film. This study guide then acts as a ‘bridging material’ between content and education audience. The frequency of this effort suggests these study guides enable greater educator engagement with content and increased interest and distribution of the film to educators. The paper Education paths for documentary distribution: DAF, ATOM and the study guides that bind them will address issues arising out of the changing needs of the education sector and the impact targeting ‘cineliteracy’ outcomes may have for Australian documentary distribution.

Improvement in Intrusion Detection With Advances in Sensor Fusion

Various intrusion detection systems (IDSs) reported in the literature have shown distinct preferences for detecting a certain class of attack with improved accuracy, while performing moderately on the other classes. In view of the enormous computing power available in the present-day processors, deploying multiple IDSs in the same network to obtain best-of-breed solutions has been attempted earlier. The paper presented here addresses the problem of optimizing the performance of IDSs using sensor fusion with multiple sensors. The trade-off between the detection rate and false alarms with multiple sensors is highlighted. It is illustrated that the performance of the detector is better when the fusion threshold is determined according to the Chebyshev inequality. In the proposed data-dependent decision ( DD) fusion method, the performance optimization of ndividual IDSs is first addressed. A neural network supervised learner has been designed to determine the weights of individual IDSs depending on their reliability in detecting a certain attack. The final stage of this DD fusion architecture is a sensor fusion unit which does the weighted aggregation in order to make an appropriate decision. This paper theoretically models the fusion of IDSs for the purpose of demonstrating the improvement in performance, supplemented with the empirical evaluation.

How to Succeed in Knowledge Transfer : Case Study of Scandinavian Alliance in Ukraine

The current study of Scandinavian multinational corporate subsidiaries in the rapidly growing Eastern European market, due to their particular organizational structure, attempts to gain some new insights into processes and potential benefits of knowledge and technology transfer. This study explores how to succeed in knowledge transfer and to become more competitive, driven by the need to improve transfer of systematic knowledge for the manufacture of product and service provisions in newly entered market. The scope of current research is exactly limited to multinational corporations, which are defined as enterprises comprising entities in two or more countries, regardless of legal forms and field of activity of those entities, and which operate under a system of decision-making permitting coherent policies and a common strategy through one or more decision-making centers. The entities are linked, by ownership, and able to exercise influence over the activities of the others; and, in particular, to share the knowledge, resources, and responsibilities with others. The research question is "How and to which extent can knowledge-transfer influence a company's technological competence and economic competitiveness?" and try to find out what particular forces and factors affect the development of subsidiary competencies; what factors influence the corporate integration and use of the subsidiary's competencies; and what may increase competitiveness of MNC pursuing leading position in entered market. The empirical part of the research was based on qualitative analyses of twenty interviews conducted among employees in Scandinavian MNC subsidiary units situated in Ukraine, using structured sequence of questions with open-ended answers. The data was investigated by comparison case analyses to literature framework. Findings indicate that a technological competence developed in one subsidiary will lead to an integration of that competence with other corporate units within the MNC. Success increasingly depends upon people's learning. The local economic area is crucial for understanding competition and industrial performance, as there seems to be a clear link between the performance of subsidiaries and the conditions prevailing in their environment. The linkage between competitive advantage and company's success is mutually dependent. Observation suggests that companies can be characterized as clusters of complementary activities such as R&D, administration, marketing, manufacturing and distribution. Study identifies barriers and obstacles in technology and knowledge transfer that is relevant for the subsidiaries' competence development. The accumulated experience can be implemented in new entered market with simple procedures, and at a low cost under specific circumstances, by cloning. The main goal is focused to support company prosperity, making more profits and sustaining an increased market share by improved product quality and/or reduced production cost of the subsidiaries through cloning approach.

Visual performance at passive level crossings with long sighting distances

The third edition of the Australian Standard AS1742 Manual of Uniform Traffic Control Devices Part 7 provides a method of calculating the sighting distance required to safely proceed at passive level crossings based on the physics of moving vehicles. This required distance becomes greater with higher line speeds and slower, heavier vehicles so that it may return quite a long sighting distance. However, at such distances, there are also concerns around whether drivers would be able to reliably identify a train in order to make an informed decision regarding whether it would be safe to proceed across the level crossing. In order to determine whether drivers are able to make reliable judgements to proceed in these circumstances, this study assessed the distance at which a train first becomes identifiable to a driver as well as their, ability to detect the movement of the train. A site was selected in Victoria, and 36 participants with good visual acuity observed 4 trains in the 100-140 km/h range. While most participants could detect the train from a very long distance (2.2 km on average), they could only detect that the train was moving at much shorter distances (1.3 km on average). Large variability was observed between participants, with 4 participants consistently detecting trains later than other participants. Participants tended to improve in their capacity to detect the presence of the train with practice, but a similar trend was not observed for detection of the movement of the train. Participants were consistently poor at accurately judging the approach speed of trains, with large underestimations at all investigated distances.

Primary Sequence That Determines the Functional Overlap between Mitochondrial Heat Shock Protein 70 Ssc1 and Ssc3 of Saccharomyces cerevisiae

The evolutionary diversity of the HSP70 gene family at the genetic level has generated complex structural variations leading to altered functional specificity and mode of regulation in different cellular compartments. By utilizing Saccharomyces cerevisiae as a model system for better understanding the global functional cooperativity between Hsp70 paralogs, we have dissected the differences in functional properties at the biochemical level between mitochondrial heat shock protein 70 (mtHsp70) Ssc1 and an uncharacterized Ssc3 paralog. Based on the evolutionary origin of Ssc3 and a high degree of sequence homology with Ssc1, it has been proposed that both have a close functional overlap in the mitochondrial matrix. Surprisingly, our results demonstrate that there is no functional cross-talk between Ssc1 and Ssc3 paralogs. The lack of in vivo functional overlap is due to altered conformation and significant lower stability associated with Ssc3. The substrate-binding domain of Ssc3 showed poor affinity toward mitochondrial client proteins and Tim44 due to the open conformation in ADP-bound state. In addition to that, the nucleotide-binding domain of Ssc3 showed an altered regulation by the Mge1 co-chaperone due to a high degree of conformational plasticity, which strongly promotes aggregation. Besides, Ssc3 possesses a dysfunctional inter-domain interface thus rendering it unable to perform functions similar to generic Hsp70s. Moreover, we have identified the critical amino acid sequence of Ssc1 and Ssc3 that can ``make or break'' mtHsp70 chaperone function. Together, our analysis provides the first evidence to show that the nucleotide-binding domain of mtHsp70s plays a critical role in determining the functional specificity among paralogs and orthologs across kingdoms.

Spectrum sensing using distributed sequential detection via noisy reporting MAC

This paper considers cooperative spectrum sensing algorithms for Cognitive Radios which focus on reducing the number of samples to make a reliable detection. We propose algorithms based on decentralized sequential hypothesis testing in which the Cognitive Radios sequentially collect the observations, make local decisions and send them to the fusion center for further processing to make a final decision on spectrum usage. The reporting channel between the Cognitive Radios and the fusion center is assumed more realistically as a Multiple Access Channel (MAC) with receiver noise. Furthermore the communication for reporting is limited, thereby reducing the communication cost. We start with an algorithm where the fusion center uses an SPRT-like (Sequential Probability Ratio Test) procedure and theoretically analyze its performance. Asymptotically, its performance is close to the optimal centralized test without fusion center noise. We further modify this algorithm to improve its performance at practical operating points. Later we generalize these algorithms to handle uncertainties in SNR and fading. (C) 2014 Elsevier B.V. All rights reserved.

Back-to-back Schottky diode adopted for the measurement of GaN films and its Schottky contacts

A new measurement method for GaN films and their Schottky contacts is reported in this paper. Instead of the fabrication of Ohmic contacts, this measurement is based on a special back-to-back Schottky diode that has a rectifying character. A mathematical model indicates that the electronic parameters of the materials can be deduced from the device's I-V data. In the experiment of an unintentionally doped n-type GaN layer with a residual carrier density 7 x 10(16) cm(-3), the analysis by the new method gives the layer's sheet resistance rho(s) = 497 Omega, the electron mobility mu(n) =, 613 cm(2) V-1 s(-1) and the ideality factor of the Ni/Au-GaN Schottky contacts n = 2.5, which are close to the data obtained by the traditional measurements: rho(s) = 505 Omega, mu(n) = 585 cm(2) V-1 s(-1) and n = 3.0. The method reported can be adopted not only for GaN films but also for other semiconductor materials, especially in the cases where Ohmic contacts of high quality are hard to make or their fabricating process affects the film's character.

不同森林管理预案下友好林业局森林景观的动态变化

Knowledge about cumulative effects of forest management alternatives on forest landscape is required to make forest management decision. In this paper,a spatially explicit landscape model,LANDIS,was applied to simulate forest landscape changes in 200 years under four management alternatives (no cutting,clearcutting,selective cutting I and II) in Youhao Forestry Bureau located in Small Khingan Mountains. APACK was used to calculate distribution area of the representative species and species age cohort for six species. The results showed:1) timber harvest decreased area percentage of representative conifer species,Pinus koraiensis,Picea koraiensis and Picea jezoensis,Larix gmelinii to some extent compared to no cutting. The most influencing cutting mode for the area percentage of Tilia amurensis and Quercus mongolica was selective cutting II,followed by selective cutting I and clearcutting. To the contrast,the change of area percentage of Betula phatyphylla was contrary to the management alternatives; 2) As to species age cohort composition,timber harvest significantly changed age structure,that is,it decreased over-matured age cohort of representative species,and increased seedling and middle-age cohort (B. phatyphylla was not included,because its area percentage of over-mature age cohort was the highest under clearcutting than other three scenarios).

性别、效价及媒体对选择冲突问题解决的影响

Choice conflict is a critical issue in decision making. This study adopted stock transaction as the task to explore the relation between share price level and conflict intensity that the subjects experienced in decision making, and the effect of price level on individual and group choice conflict resolution. The strategy people used to solve choice conflict and gender difference were also examined. Modes of interaction (face to face and through audio media) in group decision making were also studied. The main results are as follows: 1. In individual decision-marking, there is a significant gender effect on decision time. Female subjects will spent more time on the task than male subjects. 2. When making a choice decision, the individual experienced stronger conflict for price shares than for low price shares. The stronger the conflict level they feel, the more difficult to make the choice decision. 3. Four strategies were used to finish the task. Male subjects used simple strategies while female subjects used more complex strategies. 4. In group decision-making, share price level had a significant effect on selection time. People used longer selection time for low price shares than for high price shares. No significant interaction was found between share price level and Modes of interaction. 5. Modes of interaction had significant effect on satisfaction coherence of the group. Under face-to-face condition, people within one group had greater satisfaction coherence. 6. Media had no significant effect on people's perception during the experiment. Satisfaction for cooperation, successful communication and good cooperation were correlated. Self satisfaction and satisfaction of the partners others were also correlated with the satisfaction of the whole task.

UK Power Sector Challenge to National Allocation Plan Under the EU Emissions Trading Scheme Refused by the European Court of Justice

In Case T-130/06 Drax Power and others v European Commission, the Court of First Instance held that an application by Drax Power and others for annulment of Commission Decision (C(2006)426 final of 22 February 2006 concerning a proposed amendment to the National Allocation Plan notified by the UK in accordance with the EU Emissions Trading Directive was inadmissable.

Sistema de recomendação à prevenção odontológica, ortodontia e higiene oral

A tecnologia está em constante evolução e os benefícios, em diversas áreas, que ela nos traz são imensos. Uma das áreas que tem vindo a usufruir desta evolução é a medicina. Os avanços na tecnologia médica têm permitido aos médicos diagnosticar e tratar melhor os seus pacientes. O seu objetivo não é substituir o médico mas sim aconselhá-los e ajudá-los a tomar a melhor decisão face ao caso clínico que possam ter em mãos. Os sistemas de informação estão já tão “entrelaçados” com as práticas médicas que a ideia de uma instituição de prestação de cuidados médicos não os possuir é impensável. Isto porque a informação que estes sistemas processam diariamente é imensa e variadíssima (indo desde relatórios clínicos, a exames efetuados entre outros) para cada utente. As doenças orais fazem parte do grupo de patologias que afetam o maior número de pessoas no mundo. As ações preventivas para estes sintomas devem fazer parte da higiene diária dos indivíduos logo desde os primeiros anos de vida. Assim a aplicação apresentada nesta tese teve como objetivo a sensibilização para uma prática de higiene oral cuidada e constante. Teve também como objetivo a implementação de funcionalidades para gestão de dados dos pacientes da clínica, nomeadamente para o histórico clínico, ficando este armazenado numa anamnese. Para a implementação do presente projeto procedeu-se a um estudo prévio do estado da arte e ao levantamento de requisitos. Estes foram definidos através de reuniões de trabalho onde se analisou as necessidades da clínica com o objetivo de encontrar as soluções que melhor se enquadravam a cada caso. Para garantir que as metas propostas foram alcançadas, foram realizados inquéritos verificando assim o sucesso da aplicação.

Determinant factors to merger control decisions in Portugal

The present paper aims to investigate the determinant factors of Portuguese merger control. Our sample comprises 652 M&A cases occurred between January of 2003 and September of 2015. Through a probit model we have tested the relevance of product and geographic market, entry barriers, type of concentration, merger effects, year of decision and the President of the Competition Authority at the time. The results suggests that the conglomerate and vertical effects, the existence of barriers to entry as well as the number of regulatory agencies listened are the main explanatory variables to determine a need for an in-depth investigation and to make a final decision. According to the evidence, cases cleared at Phase 1 are increasing over time. The number of prohibited mergers is close to zero.

Contexte de genre, autonomie des femmes et utilisation des services de santé maternelle en milieu rural africain : analyse par modèles d’équations structurelles

La vie des femmes du continent africain et de leurs enfants continue d’être mise en danger lors de chaque accouchement car les risques de décès maternels et infantiles sont encore très élevés. Il est estimé chaque année à environ le quart du million le nombre de décès maternel et de près de quatre millions celui des enfants de moins de cinq ans. La comparaison de la situation sanitaire avec d’autres contextes permet de mieux cerner l’ampleur du problème : en Afrique sub-Saharienne, le risque de décès lié à la grossesse est de l’ordre de 1 pour 31, alors qu’il n’est que de 1 pour 4300 dans les pays industrialisés. Cette situation est évitable et, le plus souvent, résulte de la sous ou non-utilisation des services de santé maternelle, du manque de structures adéquates de soins ou de personnel de santé qualifié. Notre thèse cherche à comprendre la manière dont les inégalités de genre au sein du ménage et dans la communauté renforcent les inégalités quant à l’utilisation des services de santé maternelle, ainsi qu’aux relations empiriques qui lient les différents recours aux soins. Concrètement, elle vise à 1) proposer une mesure des normes de genre favorables à la violence contre les femmes et à analyser son influence sur leur prise de décision au sein du ménage, 2) analyser simultanément l’influence de ces normes et de l’autonomie des femmes sur le recours aux soins prénatals et à l’accouchement assisté et finalement, 3) cerner l’influence des soins prénatals sur le recours à l’accouchement assisté. Chacun de ces objectifs se heurte à un problème méthodologique substantiel, soit de mesure ou de biais de sélection, auxquels l’approche par modèles d’équations structurelles que nous avons adoptée permet de remédier. Les résultats de nos analyses, présentés sous forme d’articles scientifiques, s’appuient sur les données issues des Enquêtes Démographiques et de Santé (EDS) du Ghana, du Kenya, de l’Ouganda et de la Tanzanie et concernent les femmes vivant en milieu rural. Notre premier article propose une mesure des normes de genre et, plus exactement, celles liées à la violence contre les femmes en recourant à l’approche des variables latentes. Les cinq questions des EDS relatives à l’attitude des femmes sur la légitimation de la violence ont permis de saisir cette mesure au niveau contextuel. Les résultats suggèrent d’une part que cette mesure a de bons critères de validité puisque l’Alpha de Cronbach varie de 0.85 pour le Kenya à 0.94 pour le Ghana; les chi-deux sont non significatifs partout; le RMSEA est en dessous de 0.05; le CFI supérieur à 0.96 et les saturations sont pour la plupart supérieures à 0.7 dans tous les pays. D’autre part, à l’aide du modèle d’équations structurelles multiniveaux, nous avons trouvé qu’au-delà de leur propre attitude envers la violence contre les femmes, celles qui vivent dans un milieu où les normes de genres sont plus favorables à la violence ont plus de chances d’être de faible autonomie ou sans autonomie (comparativement à forte autonomie) dans l’ensemble des pays étudiés. Le second article documente l’influence des inégalités de genre, cernées au niveau contextuel par les normes favorables à la violence contre les femmes et au niveau individuel par l’autonomie de prise de décision au sein du ménage, sur la survenue des soins prénatals au cours du premier trimestre et sur les recours à au moins 4 consultations prénatales et à l’accouchement assisté. En utilisant également les modèles d’équations structurelles multiniveaux sur les mêmes données du premier article, nous constatons que chacune de ces variables dépendantes est fortement influencée par la grappe dans laquelle la femme vit. En d’autres mots, son lieu de résidence détermine le comportement de santé maternelle que l’on adopte. De même, en contrôlant pour les autres variables explicatives, nos résultats montrent que les femmes qui vivent dans un milieu où les normes de genre liées à la violence contre les femmes sont élevées ont, en moyenne, une plus grande chance de ne pas accoucher auprès d’un personnel qualifié au Ghana et en Ouganda, de ne pas débuter leurs soins prénatals dans le premier trimestre dans les mêmes pays, et de ne pas recourir à au moins quatre consultations prénatales en Tanzanie. Par contre, cette variable contextuelle n’influence pas significativement le recours aux soins de santé maternelle au Kenya. Enfin, les résultats montrent que les normes de genre favorables à la violence contre les femmes sont plus déterminantes pour comprendre le recours aux soins de santé maternelle dans les pays étudiés que l’autonomie de prise de décision de la femme. Dans le cadre du troisième et dernier article empirique de la thèse, nous nous sommes intéressés à l’importance des soins prénatals dans le processus de recours à l’accouchement assisté et à la place du contenu des soins reçus avant l’accouchement dans cette relation. Cet article met en exergue l’existence de biais d’endogénéité au Kenya et en Tanzanie, où sans sa prise en compte, l’effet des soins prénatals sur le recours à l’accouchement auprès d’un personnel qualifié serait fortement biaisé. De plus, il ressort qu’à l’exception du Ghana et dans une moindre mesure de la Tanzanie, cet effet est totalement médiatisé par le contenu des soins prénatals que les femmes reçoivent. L’article met ainsi en relief le rôle des prestataires de soins qui pour atteindre plus efficacement les populations doivent agir en tant que leaders au sein de leur communauté.
