AbstractDuring the last few decades, many case studies have focused on landscape transformations in response to water erosion, human impact, and climate changes. This article presents a review and comparison of the current state of knowledge on conducted research on the impact of the activities of early humans on the relief and forms of loess areas in Poland based on the results of a variety of dating methods (OSL, TL, C14, 137Cs, palynology, dendrochronology etc.). The influence of land-use activity since the first permanent settlements (8,000–5,200 BP) played a major role in the development of certain sand sediment terrain forms: gullies, river terraces, the filling of isolated depressions and alluvial fans in the loess areas. As a result, a simplified scheme of landscape evolution was created along with a map of the most investigated areas by authors. The main problem was to differentiate the influence of anthropogenic factors from natural ones occurring either simultaneously or alternatively. The developed deposits form a geo-archive which has recorded the history of environmental changes. A detailed analysis of the sedimentary structures provides the possibility to reconstruct and understand past functional responses in natural systems. It is important to consider the impact of climate change and human influence over the course of history on a specific geomorphological system. This can help to predict future land changes and likely hazards.

Environmental Landscape

The word environmental sustainability of late has been used as catch word for illustrating the climate change and subsequent sequential impact of various aspects of environmental landscape that include soil management, gaseous exchange, nutrient cycling, carbon emission, rainfall etc., Interpretation of environmental changes are interpreted based on very few trends which need not necessarily cause short term or long term impacts. The impact assessment of a region fundamentally depends on region specific history of habitat management, human interference, agricultural practices, Economic livelihood activities which depend on available natural resources and seasonality of intensity of activities. In the present study efforts are made to indentify the major NTFP based livelihood economic activities and relate the habitat management aspects along with commercial invasion that became detrimental to environmental threshold to call for sustainability alarm. The livelihoods in various developing economies have different environmental impacts. Such assessment of economic activities have any real environmentally detrimental consequences or is it being essentially over emphasizing to create such fears have been analyzed.

We hypothesize the phylogenetic relationships of the agamid genusPhrynocephalusto assess how past environmental changes shaped the evolutionary and biogeographic history of these lizards and especially the impact of paleogeography and climatic factors.Phrynocephalusis one of the most diverse and taxonomically confusing lizard genera. As a key element of Palearctic deserts, it serves as a promising model for studies of historical biogeography and formation of arid habitats in Eurasia. We used 51 samples representing 33 of 40 recognized species ofPhrynocephaluscovering all major areas of the genus. Molecular data included four mtDNA (COI,ND2,ND4,Cytb; 2,703 bp) and four nuDNA protein-coding genes (RAG1,BDNF,AKAP9,NKTR; 4,188 bp). AU-tests were implemented to test for significant differences between mtDNA- and nuDNA-based topologies. A time-calibrated phylogeny was estimated using a Bayesian relaxed molecular clock with nine fossil calibrations. We reconstructed the ancestral area of origin, biogeographic scenarios, body size, and the evolution of habitat preference. Phylogenetic analyses of nuDNA genes recovered a well-resolved and supported topology. Analyses detected significant discordance with the less-supported mtDNA genealogy. The position ofPhrynocephalus mystaceusconflicted greatly between the two datasets. MtDNA introgression due to ancient hybridization best explained this result. MonophyleticPhrynocephaluscontained three main clades: (I) oviparous species from south-western and Middle Asia; (II) viviparous species of Qinghai–Tibetan Plateau (QTP); and (III) oviparous species of the Caspian Basin, Middle and Central Asia.Phrynocephalusoriginated in late Oligocene (26.9 Ma) and modern species diversified during the middle Miocene (14.8–13.5 Ma). The reconstruction of ancestral areas indicated thatPhrynocephalusoriginated in Middle East–southern Middle Asia. Body size miniaturization likely occurred early in the history ofPhrynocephalus. The common ancestor ofPhrynocephalusprobably preferred sandy substrates with the inclusion of clay or gravel. The time of Agaminae radiation and origin ofPhrynocephalusin the late Oligocene significantly precedes the landbridge between Afro-Arabia and Eurasia in the Early Miocene. Diversification ofPhrynocephaluscoincides well with the mid-Miocene climatic transition when a rapid cooling of climate drove progressing aridification and the Paratethys salinity crisis. These factors likely triggered the spreading of desert habitats in Central Eurasia, whichPhrynocephalusoccupied. The origin of the viviparous Tibetan clade has been associated traditionally with uplifting of the QTP; however, further studies are needed to confirm this. Progressing late Miocene aridification, the decrease of the Paratethys Basin, orogenesis, and Plio–Pleistocene climate oscillations likely promoted further diversification withinPhrynocephalus. We discussPhrynocephalustaxonomy in scope of the new analyses.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

This chapter traces the early history of state-sponsored informational filmmaking in Denmark, emphasising its organisation as a ‘cooperative’ of organisations and government agencies. After an account of the establishment and early development of the agency Dansk Kulturfilm in the 1930s, the chapter considers two of its earliest productions, both process films documenting the manufacture of bricks and meat products. The broader context of documentary in Denmark is fleshed out with an account of the production and reception of Poul Henningsen’s seminal film Danmark (1935), and the international context is accounted for with an overview of the development of state-supported filmmaking in the UK, Italy and Germany. Developments in the funding and output of Dansk Kulturfilm up to World War II are outlined, followed by an account of the impact of the German Occupation of Denmark on domestic informational film. The establishment of the Danish Government Film Committee or Ministeriernes Filmudvalg kick-started aprofessionalisation of state-sponsored filmmaking, and two wartime public information films are briefly analysed as examples of its early output. The chapter concludes with an account of the relations between the Danish Resistance and an emerging generation of documentarists.

This article is part of a special Left History series reflecting upon changing currents and boundaries in the practice of left history, and outlining the challenges historians of the left must face in the current tumultuous political climate. This series extends a conversation first convened in a 2006 special edition of Left History (11.1), which asked the question, “what is left history?” In the updated series, contributors were asked a slightly modified question, “what does it mean to write ‘left’ history?” The article charts the impact of major political developments on the field of left history in the last decade, contending that a rising neoliberal and right-wing climate has constructed an environment inhospitable to the discipline’s survival. To remain relevant, Palmer calls for historians of the left to develop a more “open-ended and inclusive” understanding of the left and to push the boundaries of inclusion for a meaningful historical study of the left. To illustrate, Palmer provides a brief materialist history of liquorice to demonstrate the mutability of left history as a historical approach, rather than a set of traditional political concerns.

This paper briefly and through theoretical studies will discuss simply the problems formulated, the impact of globalization on Character education in Indonesia, as well as the paradigm of PKN learning and Character education challenges for the younger generation. It is on the ground by the declining awareness and moral values, as well as to increase the values of the characters seen in the young generations. Civic education in Indonesia has been running throughout the history of Indonesian independence, and has gone through various stages and arms, it certainly demands greater hard work of teachers to be able to increase the values of Pancasila and love of the homeland, and practice the character values which is based on the noble values of Indonesian culture into Indonesian youth.

Suicide is a global health issue accounting for at least 800,000 deaths per annum. Numerous models have been proposed that differ in their emphasis on the role of psychological, social, psychiatric and neurobiological factors in explaining suicide risk. Central to many models is a stress-diathesis component which states that suicidal behavior is the result of an interaction between acutely stressful events and a susceptibility to suicidal behavior (a diathesis). This article presents an overview of studies that demonstrate that stress and dysregulated hypothalamic-pituitary-adrenal (HPA) axis activity, as measured by cortisol levels, are important additional risk factors for suicide. Evidence for other putative stress-related suicide risk factors including childhood trauma, impaired executive function, impulsivity and disrupted sleep are considered together with the impact of family history of suicide, perinatal and epigenetic influences on suicide risk.

The history of Islam in part of what is known today as Nigeria datesto about the loth Century. Christianity dates to the late 18th Century. Bythe middle of the 19th Century, when Nigerian newspapers began to appearon the streets of Nigeria, both religions had won so many followers and extendedto so many places in Nigeria that very few areas were untouched bytheir influence. The impact of both religions on their adherents not only determinedtheir spiritual life, but influenced their social and political lives aswell. It therefore became inevitable that both religions receive coverage frommost of the newspapers of the time. How the newspapers as media of informationand communication reported issues about the two religions is thetheme of this paper.Rationale for the StudyThe purpose of this study is to highlight the context in which such earlynewspapers operated and the factors that dictated their performance. Thisis because it is assumed that when a society faces external threat to its territory,culture, and independence, all hands (the press inclusive) ought tobe on deck to resist the threat with all might. Were newspapers used as verbalartillery and how did they present each religion? It is also assumed thatin a multireligious society a true press should be objective and serve as avanguard in the promotion of the interest of the people in general and notcreate or foster an atmosphere of religious conflict. The study also aims atfinding out whether the papers promoted intellectual honesty and fosteredthe spirit of unity particularly when the society was faced with the encroachmentof the British who posed a threat to their freedom, culture, economy ...
