Rocks have the ability to preserve magnetic information used in determining past geographic formations. The purpose of this report is to determine the past location of a site from a given data set’s magnetic information and the calculations found through their application to paleomagnetism. Magnetic information includes the rock sample’s location and concentration of trace magnetic particles which were used to find declination and inclination on site. The sample’s paleolatitude and paleolongitude are calculated using trigonometric equations that are derived using calculus. After a statistical analysis, these results are compared to the present day’s magnetic poles to determine the past location of the site. This location, along with the magnetic information, is combined to construct a past geographic formation that existed a billion years ago. This process reveals that the site currently found in southwest Namibia, was located near the coast of modern-day northwest Africa during the late Mesoproterozoic Era within a 95% certainty. When compared to past literature these results show the reliability and role of paleomagnetism, as well as the importance of collaboration across the geosciences.

Diverse historical, cultural landscapes can be found in many parts of the world, and also in rural areas. They are a challenge for interdisciplinary research. One of the gradually disappearing components of rural cultural landscapes in Poland is the scarecrow. The objective of this paper was to analyse the role of the scarecrow in the Polish rural cultural landscape today. The field research was aimed at determining whether the scarecrow can be seen in Polish rural areas, and if yes, what the circumstances and its forms are. A site visit yielded copious photographic records of rural areas. The investigated area was selected following a literature analysis and analysis of environmental and economic conditions on the regional level in Poland. The visit demonstrated that although scarecrows are part of the cultural landscape of the Polish countryside, they are slightly more modest in their appearance than in the past. Scarecrows are placed in small, family-owned agricultural holdings that have time to uphold local traditions.

In this article, I will examine the internet through the lens of consumption and waste studies. The internet will be conceived of as the place where the cultural waste of music – in the form of marginal artefacts and obsolete media (such as vinyl records, tapes, and ephemera) – can effectively be excavated, recirculated and re-mediated by means of systematic digitisation and uploading. The redemptive role of popular and spontaneous digital archives (such as the video platform YouTube or dedicated audio blogs) will be critically examined. Complementarily, I will underline the idea that the internet also encourages a paradoxical return of tangible artefacts, as the work of digital music collectors may prompt the actual reissue of previously lost music objects (a tendency that is exemplified in the UK by the work of British contemporary reissue record labels such as Trunk Records or Finders Keepers). The internet will be discussed as an ambiguous site of redemption, forming the basis for a nostalgic retro-consumption of music. As such, it will be conceived of as a site of memory and as a possible archive, though the ambiguity of such a term will be discussed. I will reflect upon the cultural meaning of digital archives that, as they are ceaselessly renewed, continue to erase themselves. Lastly, I will suggest that the forms of redemption that are enabled by the internet are strictly inseparable from the production of further layers of cultural waste. Departing from Straw's assertion that the internet ‘has strengthened the cultural weight of the past, increasing its intelligibility and accessibility’ (2007, 4), I will point out that the internet may accelerate the processes of cultural obsolescence and oblivion that it seeks to suspend.

This paper correlates as-received relief valve test results with current inspection intervals and presents conclusions based on statistical analysis. During the past three year period over 500 used valve proof test records from a site population of 3500 safety relief valves were acquired and reviewed. Collection and analysis of spring-loaded relief valve test data continues with the goal being to increase the test intervals within guidelines, reduce costs, and maintain safety margins. Based on current test intervals of 1–7 years, time in service appears to have a minimal effect on valve performance. Seat material and inlet size are identified as having a statistically significant impact on valve performance. An increase in TP/SP of 1–2% per year was noted for soft seated, small inlet sizes. Photographs of failed valve internals and discussion of failure causes are included.

The significance of morphological variation in Acheulean bifaces has been a central issue in Palaeolithic research for well over a century. For much of that period interpretation has been dominated by culture-historical models and it is only in the past 20 years that other explanatory factors have received adequate attention. This paper examines the combined role of several of these factors – namely raw materials, reduction intensity, and function – on biface variability in the British Isles, with special reference to the two major shaped-based ‘tradition’ devised by Roe (1967; 1968). First-hand examination of bifaces from 19 assemblages suggests that final biface shape depends largely on the dimensions of the original raw materials and the technofunctional strategies designed to deal with them. Through these observations a new model is generated and tested. This suggests that the patterning in the British Acheulean simply reflects the nature of the resources available at a site and the hominid procurement and technological strategies used to exploit them. According to this model, well-worked ovates with all-round edges were preferentially produced wherever raw materials were large and robust enough to frequently support intensive reduction procedures, usually when obtained from primary flint sources. Assemblages characterised by partially-edged, moderately-reduced pointed forms were only manufactured when smaller, narrower blanks, that imposed restrictions on human technological actions regarding the location and extent of working, were exploited. Such blanks were usually obtained from a secondary flint source, such as river gravel. Thus, Roe's pointed and ovate ‘traditions’ are seen not as the products of different biface making populations, but as the same broad populations coping with the exigencies of a heterogeneous environment, using different resources in an adaptive, flexible manner.

How do print museums develop an innovative approach to their collection while providing their visitors with historical context? Using artistic printmaking to keep the heritage of print alive, many ‘working museums’ promote the global knowledge of letterpress, relying on international collaborations to generate innovative and creative approaches. The the International Council of Museums’ guidelines, only refers to a ‘working museum’, but does not offer a clear definition of what this is. How can an operational print museum demonstrate innovative practices and retain the existing knowledge of letterpress? This paper will examine the ‘working print museum’, how it can be not only a site for reimagining the past but provide new forms of research and pioneering adaptations of old technologies. This research is inspired by the concept that as the initial infatuation with certain technologies has passed, we have entered a relationship with them in expanded artistic adventure. The paper promotes the idea that printmaking and letterpress allow for a collaborative approach which not only serves to strengthen communities but can be more than a mere reproduction of a historical process and allow for expanded experimentation. Through an in-depth look of the contemporary practices, ethos, and developments of printing museums in Europe, this paper raises questions surrounding the role of museums in this post-digital world. It will look at the future of the ‘working print museum’ and suggest how letterpress practices can extend through international and European collaborations.

This study questions the role of media in the formation of society’s memory regarding the asylum seeker struggle in Israel. Through analyzing 180 news articles published during the daily coverage of the refugees’ protest in Israel between December 2013 and January 2014, this study offers an opportunity to explore the mediated environment that also shapes the refugees’ situation in Israel and the role of the printed press in a memory contestation. The study demonstrates that while traditional media are a site in which different versions of the past, even including the refugees’ own version, are being contested and evaluated, they are not enough to guarantee that refugees will gain recognition as such, because traditional media maintain the power to shape and construct the debate in ways that do not always support the refugees’ claims.

The role of electron microscopy and associated techniques is assured in diagnostic pathology. At the present time, most of the progress has been made on tissues examined by transmission electron microscopy (TEM) and correlated with light microscopy (LM) and by cytochemistry using both plastic and paraffin-embedded materials. As mentioned elsewhere in this symposium, this has revolutionized many fields of pathology including diagnostic, anatomic and clinical pathology. It began with the kidney; however, it has now been extended to most other organ systems and to tumor diagnosis in general. The results of the past few years tend to indicate the future directions and needs of this expanding field. Now, in addition to routine EM, pathologists have access to the many newly developed methods and instruments mentioned below which should aid considerably not only in diagnostic pathology but in investigative pathology as well.

The Relationship

The rise of e-commerce has brought considerable changes to the relationship between firms and consumers, especially within international business. Hence, understanding the use of such means for entering foreign markets has become critical for companies. However, the research on this issue is new and so it is important to evaluate what has been studied in the past. In this study, we conduct a systematic review of e-commerce and internationalisation studies to explicate how firms use e-commerce to enter new markets and to export. The studies are classified by theories and methods used in the literature. Moreover, we draw upon the internationalisation decision process (antecedents-modalities-consequences) to propose an integrative framework for understanding the role of e-commerce in internationalisation

Financial crime in Nigeria – including money laundering – is ravaging Nigeria's economic growth. In the past few years, the Nigerian government has made efforts to tackle money laundering by enacting laws and setting up several agencies to enforce the laws. However, there are substantial loopholes in the regulatory and enforcement regimes. This article seeks to unravel the involvement of the churches as key drivers in money laundering crimes in Nigeria. It concludes that the permissive secrecy which enables churches to conceal the names of their financiers and donors breeds criminality on an unimaginable scale.
