Seven species of Volvocaceae were recorded in the lower Vistula River and its oxbow lakes, including <em>Pleodorina californica</em> for the first time in Poland. Three species – <em>Eudorina cylindrica</em>, <em>E. illinoisensis</em> and <em>E. unicocca</em> – were found in the Polish Vistula River in the 1960s and 1970s, as well as at present. They are rare species in the Polish aquatic ecosystems. Three species are common both in the oxbow lakes and in the Vistula River: <em>Eudorina elegans</em>, <em>Pandorina morum</em> and <em>Volvox aureus</em>. New and rare Volvocaceae species were described in terms of morphology and ecology; also photographic documentation (light microscope microphotographs) was completed.

The evolution of the importance of public opinion in Mexico is intertwined with the emphasis of scholars, both foreign and Mexican, introducing survey research techniques. These efforts became more common in the 1960s and 1970s, but became increasingly significant in the 1980s, when major newspapers and other publications begin to sponsor wide-ranging public opinion polls. Public opinion polls played a critical role in Mexico’s democratic political transition during the 1980s and 1990s, informing ordinary Mexicans about how their peers viewed candidates and important policy issues, while simultaneously allowing citizens, for the first time, to assess a potential candidate’s likelihood of winning an election before the vote, while also confirming actual election outcomes through exit polls. Polling data reveal changing social, religious, economic, and political attitudes among Mexicans over time, revealing the importance of both traditional and contemporary values in explaining citizen behavior.

The Boxed Springs Mound site (41UR30) is one of three major Early Caddoan (ca. A.D. 900- t 200) multiple mound centers in the Sabine River basin of northeastern Texas, the others including the Jamestown (41SM54) and Hudnall-Pirtle (41RK4) sites upstream and downstream, respectively, from Boxed Springs. It is situated on a large and prominent upland ridge projection that extends from a bluff on the Sabine River about 500 m north to where the landform merges with a broader stretch of uplands and Bienville alluvium. Sediments on the site are Trep loamy fine sand, a relatively fertile soil. The site is approximately 1.6 km west of the confluence of Big Sandy Creek and the Sabine River, but the old channels, sloughs, and oxbow lakes on both sides of the upland ridge and alluvial terrace suggest that previous channels of the Sabine River as well as Big Sandy Creek ran from north to south immediately adjacent to the site. When the Boxed Springs site was originally recorded by Sam Whiteside, an avocational archeologist from Tyler (see Walters and Haskins, this volume) in the early 1960s, it had four earthen mounds arranged around an open area or central plaza. The four mounds apparently included two low "structural" or house mounds with clay floors at the southeastern and southwestern ends of the plaza (Mounds #2 and #7 on a ca. 1962 sketch by Whiteside), one burial mound about 12 x 8 m in size and 1 m in height at the northwestern plaza edge (Mound #3), and a flat-topped mound of unknown function at the northeastern end of the plaza (Mound #6). There were borrow pits apparently visible to the east of Mound #3 and south of Mound #6, and occupation areas/midden deposits along the uplands at the southern edge of the site as well as north and northwest of Mound #3. Some years ago, while Dr. James E. Bruseth and Dr. Timothy K. Perttula were documenting a large collection of vessels and stone tools from the Boxed Springs site, they became aware of the fact that a cremation burial with associated vessels had been dug at the site. A few years later, the cremated remains from that burial were turned over to Dr. Perttula for study. In this paper, Diane E. Wilson summarizes for the first time the results of her bioarchaeological analyses of the cremated burial. With this information now available, it seemed appropriate to provide an archaeological context--as it was known--on the cremated burial, and also summarize in one place the available information on the archaeological record from the Boxed Springs site. Key to this effort was the fact that Mark Walters provided unpublished information and notes from the 1960s archaeological investigations by Sam Whiteside at the Boxed Springs site. Although it is a major Early Caddoan mound center, the archaeology of the Boxed Springs site is very poorly known. We hope that this paper on a cremated burial from the site, as well as a discussion of previous archaeological investigations at Boxed Springs, will rectify this situation to a certain extent, and also spur renewed professional archaeological interest in this very significant prehistoric Caddoan mound center.

Abstract In the most service life models of reinforced concrete structures the initiation phase is the most crucial, because according to models, service life of the structure will end underestimation on conservative side when carbonation achieves the reinforcement for the first time. The square root model is widely used in predicting carbonation depth of reinforced concrete. The model is based on diffusion laws and thereby arguable for inhomogeneous concrete. The model was evaluated by field measurements from one existing concrete building by conducting condition investigation twice at a time interval of 20 years. Samples were taken from exposed aggregate concrete sandwich panels and balcony side panels. Compared to the data collected from large number of buildings, the measured carbonation rates were very common for Finnish concrete buildings made during the 1960s and 1970s. According to this study, in solid concrete the progress of carbonation of concrete can be predicted reliably with Fick’s second law. This model, however, gives too pessimistic predictions for concrete suffering from freeze-thaw damage. Therefore, a new model has been presented for damaged concrete.

Patrícia Mourão de Andrade offers an impassioned portrait of the actress and filmmaker Helena Ignez, a foundational figure in Brazilian filmmaking of the 1960s and 1970s. Long ignored by a national historiography blinded by its own patriarchal distortions, Ignez has only gained recognition in the last fifteen years for her contributions to Brazilian cinema. Moving behind the camera for the first time in 2005, Ignez has created a body of work that brings the anarchic spirit of the Cinema Marginal movement of the late 1960s to Brazilian cinema of the 2000s. This article offers a comprehensive survey and assessment of Ignez’s career, from her first film, O pátio (1959), directed by Glauber Rocha, who became her first husband, to her memorable performances of the 1960s, to her years of political exile, to her recent, late renaissance.

This article traces Ken Russell's explorations of war and wartime experience over the course of his career. In particular, it argues that Russell's scattered attempts at coming to terms with war, the rise of fascism and memorialisation are best understood in terms of a combination of Russell's own tastes and personal style, wider stylistic and thematic trends in Euro-American cinema during the 1960s and 1970s, and discourses of collective national experience. In addition to identifying Russell's recurrent techniques, this article focuses on how the residual impacts of the First and Second World Wars appear in his favoured genres: literary adaptations and composer biopics. Although the article looks for patterns and similarities in Russell's war output, it differentiates between his First and Second World War films by indicating how he engages with, and temporarily inhabits, the stylistic regime of the enemy within the latter group.

Brainwashing assumed the proportions of a cultural fantasy during the Cold War period. The article examines the various political, scientific and cultural contexts of brainwashing, and proceeds to a consideration of the place of mind control in British spy dramas made for cinema and television in the 1960s and 1970s. Particular attention is given to the films The Mind Benders (1963) and The Ipcress File (1965), and to the television dramas Man in a Suitcase (1967–8), The Prisoner (1967–8) and Callan (1967–81), which gave expression to the anxieties surrounding thought-control. Attention is given to the scientific background to the representations of brainwashing, and the significance of spy scandals, treasons and treacheries as a distinct context to the appearance of brainwashing on British screens.

This article reports findings of research into the far-reaching plan to ‘modernise’ the Scottish economy, which emerged from the mid-late 1950s and was formally adopted by government in the early 1960s. It shows the growing awareness amongst policy-makers from the mid-1960s as to the profoundly deleterious effects the implementation of the plan was having on Glasgow. By 1971 these effects were understood to be substantial with likely severe consequences for the future. Nonetheless, there was no proportionate adjustment to the regional policy which was creating these understood ‘unwanted’ outcomes, even when such was proposed by the Secretary of State for Scotland. After presenting these findings, the paper offers some consideration as to their relevance to the task of accounting for Glasgow's ‘excess mortality’. It is suggested that regional policy can be seen to have contributed to the accumulation of ‘vulnerabilities’, particularly in Glasgow but also more widely in Scotland, during the 1960s and 1970s, and that the impact of the post-1979 UK government policy agenda on these vulnerabilities is likely to have been salient in the increase in ‘excess mortality’ evident in subsequent years.

The mid-1960s saw the beginnings of the construction of a Palestinian political field after it collapsed in 1948, when, with the British government’s support of the Zionist movement, which succeeded in establishing the state of Israel, the Palestinian national movement was crushed. This article focuses mainly on the Palestinian political field as it developed in the 1960s and 1970s, the beginnings of its fragmentation in the 1990s, and its almost complete collapse in the first decade of this century. It was developed on a structure characterized by the dominance of a center where the political leadership functioned. The center, however, was established outside historic Palestine. This paper examines the components and dynamics of the relationship between the center and the peripheries, and the causes of the decline of this center and its eventual disappearance, leaving the constituents of the Palestinian people under local political leadership following the collapse of the national representation institutions, that is, the political, organizational, military, cultural institutions and sectorial organizations (women, workers, students, etc.) that made up the PLO and its frameworks. The paper suggests that the decline of the political field as a national field does not mean the disintegration of the cultural field. There are, in fact, indications that the cultural field has a new vitality that deserves much more attention than it is currently assigned.
