This study set out to test the theoretical premise of the SSARC model of pedagogic task sequencing, which postulates that tasks should be sequenced for learners from cognitively simple to complex. This experiment compared the performance of three tasks differing in cognitive complexity in a simple–complex sequence versus in the absence of any other tasks. There were two groups in the study: (1) participants who performed the three tasks in the simple–complex sequence, and (2) participants who performed either the simple, the complex, or the most complex task. The participants’ speech was analysed using fluency, accuracy, and complexity measures. The results indicate that simple–complex sequencing led to a higher speech rate, greater dysfluency, enhanced accuracy, and greater structural complexity, as compared to individual task performance. The results are discussed in terms of the SSARC model and pedagogical implications of the findings are presented.

The paper deals with some problems of musical institutions management in the Volga Region in 1939 1945 on the example of 8 musical cultural models of rear, frontal and front-line types: Kuibyshev, Ulyanovsk, Penza, Saratov, Engels, Kazan, Stalingrad, Astrakhan. The author reconstructs the structure and functional complex of the management component, describes the responsibilities of the commissioners of Performances and Repertoire Control Main Department at different levels and detects the role of the Communist party in the music management of the region. The author notes instability and incomplete correspondence of the administrative board in some models as a negative factor. A significant impact on musical culture management in the region provided emergency-revaluation processes: range of competencies and staff. Changes in the geography of governance structures affected the Stalingrad model of front type. Some actual data about the material provision of the management component are provided: departments placement and employees salaries. Structural complexity of administrative areas during 1939 1945 is stated. The author restores a number of regional culture managers names and their professional affiliation.

RESUMEN Este trabajo desarrolla las circunstancias bajo las cuales, desde sus inicios, la orientación profesional en Argentina se caracterizó por el hecho de contemplar especialmente las condiciones sociales de la población a la que dirigía su accionar. Efectivamente, la orientación profesional en este país estuvo básicamente relacionada con la detección de determinadas características personales y su relación con capacidades laborales específicas, dentro de un contexto en el cual los parámetros vinculados a aspectos sociales eran incluidos como uno de los articuladores fundamentales de dicha tarea. En Argentina es posible apreciar cómo, durante las últimas décadas, la exclusión social producto de los crecientes niveles de pobreza, la falta de oportunidades, el desempleo y los bajos niveles de educación, han in‐ troducido nuevas perspectivas en el panorama referido al proceso de orientación. Si bien éste históricamente ha contemplado los aspectos sociales y económicos, el elevado grado de dificultad estructural de la situación actual representa nuevos y complejos desafíos en la tarea de orientación. En este artículo se analiza el valor del orientador comprometido con factores socio‐económicos de las poblaciones a las que dirige su tarea y la importancia que la responsabilidad social adquiere en estas circunstancias. Responsabilidad que incluso se encuentra avalada en Argentina, tanto por códigos de ética locales como por las propias competencias internacionales de la orientación profesional. ABSTRACT This work points out the circumstances in which, from its very beginning, professional guidance in Argentina has been specially characterized by taking into account the particular social situation of the individuals and populations to whom the specific practice was directed. In fact, professional guidance in this country was basically related to the detection of certain individual factors and its relation to specific labour abilities, within a context in which social matters’ related factors were considered as a main axe to the future developing of the whole guidance process. In Argentina, during the last decades, social exclusion due to increasingly poverty index, the lack of opportunities, the unemployment and a low educational level, have introduced hard new conditions into careers advice. Even though this process has always considered social and economical matters, the high level structural complexity of current situation means new and hard challenges in the guidance task. This paper analyzes the central role of careers advisers’ commitment to socio‐economical circumstances of the individuals and population to whom the task is directed, and the importance of social responsibility involved through these circumstances. This responsibility is also supported in Argentina, not only by local ethics codes, but by professional international guidance competences as well.

Coralligenous formations are biogenic structures typical of the underwater Mediterranean seascape. Their intricate, multi-layered species assemblages are composed of perennial, long-lived organisms, particularly vulnerable to natural or human-induced disturbances. Despite their high ecological role and conservation value, few studies have addressed the assemblages outside the NW Mediterranean. This is the first quantitative assessment of coralligenous in the N Aegean Sea (NE Mediterranean), specifically focusing at the upper bathymetric limit of assemblages that are dominated by the yellow gorgonian Eunicella cavolini. The number and percent cover of macrobenthic species were studied at depths of 18 to 35 m, using a photoquadrat method. A total of 99 benthic taxa were identified, out of which 89 perennial ones were used to investigate spatial patterns in assemblage structure, composition, and biodiversity. A mean number of 47 perennial taxa were recorded per site, with encrusting coralline algae and sponges being the dominant groups in percent cover and species number, respectively. Across the studied localities, structural complexity and community composition were overall similar, but assemblages presented distinctive differences at the level of sites highlighting the role of local abiotic and anthropogenic factors in the shaping of the coralligenous. Compared to the rest of the Mediterranean, assemblages hosted a similar number of taxa. However, the number and percent cover of erect bryozoans were generally low, while, apart from E. cavolini, other erect anthozoan species were absent. This work provides an important baseline for comparisons and monitoring at a local or Mediterranean scale level.

As shown earlier, the algorithmic complexity, like Shannon information and Boltzmann entropy, tends to increase in accordance with the general law of complification. However, the algorithmic complexity of most material systems does not reach its maximum, i.e. chaotic state, due to the various laws of nature that create certain structures. The complexity of such structures is very different from the algorithmic complexity, and we intuitively feel that its maximal value should be somewhere between order and chaos. I propose a formula for calculation such structural complexity, which can be called - structuredness. The structuredness of any material system is determined by structures of three main types: stable, dissipative, and post-dissipative. The latter are defined as stable structures created by dissipative ones, directly or indirectly. Post-dissipative structures, as well as stable, can exist for an unlimited time, but at the micro level only, without energy influx. The appearance of such structures leads to the “ratchet” process, which determines the structuregenesis in non-living and, especially, in living systems. This process allows systems with post-dissipative structures to develop in the direction of maximum structuring due to the gradual accumulation of these structures, even when such structuring contradicts the general law of complification.

<em>Abstract.</em>—We review published literature examining the role of wood in mediating biodiversity in aquatic ecosystems, identifying the components of biodiversity, taxonomic groups, and scales that have been studied, and highlight gaps in existing knowledge. The components of biodiversity most frequently studied include species diversity (or richness) of macroinvertebrates and fishes, structural complexity within habitat units, and the diversity of habitats found in a stream reach. Many of these studies show that large wood increases biodiversity by providing stable, hard substrates for colonization by periphyton and macroinvertebrates; by increasing microhabitat complexity; and by shaping channel morphology by controlling patterns of erosion and deposition in stream reaches. The abundance of wood in channels, as well as its functional role, varies greatly in longitudinal, lateral, and vertical dimensions along the river corridor. The influence of wood on community structure and ecosystem processes also varies across these dimensions and from stream headwaters to river mouths and nearshore marine environments. Thus, wood can influence biodiversity at all of these scales. Numerous studies, however, have failed to show an effect of wood on biodiversity. These conflicting results illustrate that wood abundance, its functional role in streams, and its influence on biodiversity depend on a variety of factors, and it is the total effect of all these factors, not simply the presence of large wood, that determines patterns of biodiversity.
