Abstract This paper subscribes to the concept of Key Geoheritage Area (KGA) which is currently being developed. Three localities in northeast Brazil are described as possible candidates for KGA. They represent the diversity of erosional granite landscapes found in cratonic areas. Pedra da Boca is an impressive cluster of tall domes rising from the marginal escarpment of Borborema Plateau, with gigantic tafoni. Pai Mateus is located on the Borborema Plateau and consists of a group of low granite elevations (ruware, whalebacks) with residual boulders scattered on their surfaces. These boulders are hollowed out by weathering, providing another very distinctive type of tafoni. Quixadá area is an inselberg landscape, with a few dozens of bedrock hills rising from the plain. Among minor features, karren are ubiquitous. Collectively, these three sites show different types of cratonic granite scenery, a multitude of medium-size and minor geomorphic features, and illustrate pathways for inselberg formation and decay through long-term weathering and erosion. Therefore, they are considered to fit the concept of KGA. In addition, each landscape has considerable aesthetic and scenic values, with great potential for geotourism and geoeducation. Nevertheless, their current conservation status is low and geointerpretation nearly nonexistent and these challenges are to be addressed in the future.

AbstractBackground. The article under consideration focuses on the comprehensive research of CF,integrating stylistic, lexico-grammatical and communicative contexts of its realization in publicisticdiscourse of the French language. The purpose of the study is to investigate the stylistic and communicative peculiarities ofthe publicistic type of discourse, research the discourse differences between publicistic and literarytypes of discourse, define the types of futural semantics in publicistic type of discourse in theFrench language and specify their communicative potential. Methods of the research. The article under discussion applies comprehensive approach toCF research: interpretation procedure to differentiate modus components and separate modalmeanings of CF, method of semantic generalization to study the CF tense forms usage, thediscourse analysis operations to discover the remote structure with futural meaning, contextual andfunctional-stylistic analyses to discover CF semantics in separate microcontexts. Results of the investigation. The notions of strategy and tactics of language communication,overall context of utterance and speaker’s communicative aim producing, realized within a singlecommunicative act, are the foundation of the communicative-pragmatic analysis of the types ofdiscourse, implementing CF. Publicistic discourse is regarded as a certain type of discourse, as acorrelate of publicistic style. The communicative-pragmatic effect realization in a certain type ofdiscourse may involve the combination of semantic-stylistic and contextological analysis of theutterance. The analysis of the factual material proves that predictive publicism makes a significantpart of CF rate of usage. Discussion. It has been found out that publicistic discourse feeds into existential discoursebasic model. Its essence is in semiotization of the future reality in the long term or near-termperspective. The comparison of the tenses usage in publicistic and literary texts has demonstratedthe difference in their temporal structure – publicistic style, as opposed to literary style, ischaracteristic of preservation of frequency of the timeframe. Publicistic style, as well as literarystyle, contains futural contexts, which include integrative combinations of the verbs of movement,semantics of verbs, conveying different types of aspectual situations and grammar means.Publicistic type of discourse of the French language contains all four moods of French, able torealize two major forms of futural semantics – “future prediction” and “volitive future”. Prospectsof the future investigations lie in the study of CF expression in different types of language acts suchas: emotional-evaluative, declarative, directive, commissive, representative, in particular, wishes,permissions, demands, hints. Moreover, it seems highly potential to research CF in different typesof discourse, namely, in esoteric, culinary, advertese, intensional, etc.

PurposeThe purpose of this paper is to study the effect of different parts (predictable and impact) of different types of speculative behavior (intraday speculation, medium-term speculation and long-term speculation) on future fluctuations in the underlying index.Design/methodology/approachThe authors input information about heterogeneous speculative behavior into the HAR-RV model to study the effect of different parts (predictable and impact) of different types of speculative behavior (intraday speculation, medium-term speculation and long-term speculation) on the future fluctuation of the underlying index.FindingsThe authors find that the increase in intraday speculation will exacerbate spot market volatility; and the expected increase of long-term value speculation can reduce market volatility, but the shock of speculation will exacerbate market volatility.Practical implicationsThe authors suggest that regulators should strictly limit speculative intraday trading, and also focus on the long-term value speculation that decreases market volatility, in order to guide the benign development of the markets that stabilize abnormal market fluctuations.Originality/valueFirst, in view of the correlation between the futures and spot markets, the authors put forward a new proxy for the speculation degree. Second, the authors input heterogeneous speculative behavior into the HAR-RV model to study the effects of different parts (predictable and impact) on different types of speculative behavior (intraday speculation, medium-term speculation and long-term speculation) on the future fluctuation of the underlying index.

Phaseolus Species

Rare and endemic plants, such as the wild species of Phaseolus (Fabaceae) in northeastern Mexico, deserve high priority in conservation efforts because of their uniqueness and usefulness as plant genetic resource. This is particularly important because during the last decades, some of these species have become endangered because of anthropogenic and natural factors. The study aimed to determine the current conservation status of 11 reported wild bean species in northeastern Mexico, using wild bean data from 77 expeditions to the states of Nuevo León and Tamaulipas during the period 1869-2013.The conservation status of the different species was determined according to the Official Mexican Standard NOM-059-SEMARNAT-2010. The categories of risk were based on four indicators: amplitude of distribution, habitat status, biological vulnerability and impact of human activity. The following eight wild Phaseolus species are not at risk of extinction: P. albiflorus, P. glabellus, P. leptostachyus, P. maculatifolius, P. neglectus, P. pedicellatus, P. vulgaris and P. zimapanensis. On the other hand, P. altimontanus Freytag & Debouck is categorized as threatened; P. novoleonensis Debouck, in danger of extinction; and P. plagiocylix Harms, possibly extinct.  Current in situ and ex situ conservation programs need to be strengthened and expanded for the medium- and long-term protection of wild bean species in northeastern Mexico.

The conservation status of the Blue-throated Macaw Ara glaucogularis, a Bolivian endemic, is assessed using the most recent information available. The known range of the species is patchily distributed within an 8,600 km2 area of lowland savanna–forest habitat in the Beni department, under private ownership for cattle ranching, which is the main form of land use in the region. Population surveys of the Blue-throated Macaw revealed this species to exist in very low numbers. The immediate threat to the species is illegal trapping for the live bird trade. Effects of cattle grazing and savanna burning may modify habitat characteristics, but there is no direct evidence suggesting that these factors negatively influence the ecological requirements of Ara glaucogularis. The species is highly associated with the Attalea phalerata palm, which it uses for feeding and nesting. Current conservation efforts include: population and distribution surveys and assessment of habitat requirements; environmental awareness targeted at landowners and ranch personnel; collaboration with subnational and central government bodies; and development of strategies to curtail parrot trafficking activities. Recommendations for the long-term conservation of the species include increasing the involvement of landowners to strengthen protection for wild macaws; working with the Bolivian government on strategies to curb macaw trafficking; increasing environmental education activities with local inhabitants; basic research on breeding requirements and limitations of wild Blue-throated Macaws; and investigating the application of private reserves to the Blue-throated Macaw range.

Conservation Actions

The decline of many species towards extinction has largely focused conservation efforts on ensuring that species remain extant. However, conservationists have long recognised the need to complement this by aiming to recover depleted populations throughout a species’ range and to restore species to ecosystems from which they have been extirpated. The main objectives of the IUCN Green Status of Species are: to provide a standardised framework for measuring species recovery; to recognise conservation achievements; to highlight species whose current conservation status is dependent on continued conservation actions; to forecast the expected conservation impact of planned conservation action; and to elevate levels of ambition for long-term species recovery. These objectives together encourage conservation towards species recovery, throughout a species’ range.

This review surveys relevant and recent data of the pertinent literature regarding the acute effect of alcohol on various kinds of memory processes with special emphasis on working memory. The characteristics of different types of long-term memory (LTM) and short-term memory (STM) processes are summarized with an attempt to relate these to various structures in the brain. LTM is typically impaired by chronic alcohol intake but according to some data a single dose of ethanol may have long lasting effects if administered at a critically important age. The most commonly seen deleterious acute effect of alcohol to STM appears following large doses of ethanol in conditions of “binge drinking” causing the “blackout” phenomenon. However, with the application of various techniques and well-structured behavioral paradigms it is possible to detect, albeit occasionally, subtle changes of cognitive processes even as a result of a low dose of alcohol. These data may be important for the consideration of legal consequences of low-dose ethanol intake in conditions such as driving, etc.
