Full textAbstract:
The object of study in the present article is birds, more precisely the sounds of birds as they are represented in Estonian nature writing. The evolutionary and structural parallels of bird song with human language are reviewed. Human interpretation of bird sounds raises the question, whether it is possible to transmit or “translate” signals between the Umwelts of different species. The intentions of the sender of the signal may remain unknown, but the signification process within human Umwelt can still be traced and analysed. By approaching the excerpts of nature writing using semiotic methodology, I attempt to demonstrate how bird sounds can function as different types of signs, as outlined by Thomas A. Sebeok. It is argued that the zoosemiotic treatment of nature writing opens up a number of interesting perspectives that would otherwise remain beyond the scope of traditional literary analysis.

<p>In offered research, we propose to observe diurnal soaring birds to check, whether there the positions of birds in formations are such, that the wing tip interval and depth meet the predictions of aerodynamic theory for achievement of maximal conservation of energy or predictions of the hypothesis of communication. We also can estimate, whether adverse conditions of a wind influence the ability of birds to support formation. We can assume that windy conditions during flight might make precision flight more difficult by inducing both unpredictable bird and vortex positions. To this, we need to found change in wing-tip spacing variation with increasing wind speed, suggesting or rejecting that in high winds bird skeins maintained similar variation to that on calm days. The interrelation between variation of mean depth and wind speed should prove this hypothesis. Little is known about the importance of depth, but in high winds the vortex is likely to break up more rapidly and its location become unpredictable the further back a bird flies; therefore, a shift towards skeins with more regular depths at high wind speeds may compensate for the unpredictability of the vortex locations. Any significant relationship between the standard deviation of wing-tip spacing and wind speed suggests that wind has a major effect on optimal positioning.</p> <p>Results of proposed study will be used also as the auxiliary tool in radar research of bird migration, namely in research of flight features of soaring birds. It is extremely important to determine all pertinent characteristics of flock for model species, namely flocking birds.</p> <p><em>Kew words: birds, flock, radar, flight</em></p><p> </p>

Riefani MK, Soendjoto MA, Munir AM. 2019. Bird species in the cement factory complex of Tarjun, South Kalimantan, Indonesia. Biodiversitas 20: 218-225. The factory complex of PT Indocement Tunggal Prakarsa Tbk., Tarjun, South Kalimantan, Indonesia consists of cement manufacturing plants and employee settlements. Supporting facilities for the two main areas are open spaces in the form of waters (lakes, small rivers), grasslands (golf courses, grassy fields with several woody individuals growing on it), and forests (mangrove forests, secondary lowland forests, including shrubs). However, the data related to bird species that live in complex are not available yet. The purpose of this study was to inventory bird species in the ITP complex and to analyze qualitatively the presence of birds. These data will be used as a baseline for the development of the complex, comparative data for birds in the operational area of mining located 27 km outside the complex, and the completeness of the requirements for submitting a company performance rating (Proper). Birds were inventoried four periods between 2015-2016 at 06:00 - 08:00 and 16:30 - 18:00. The period here was treated as repetition. Observers equipped with binoculars and telephoto cameras walked around through footpaths and roads exploring the whole complex. In water and grassland areas, birds recorded can be at an observation distance of more than 50 m, whereas in forest areas, birds recorded were at a maximum distance of 50 m. A total of eighty-seven species and 41 families of birds were recorded. Of them, eighteen species and 8 families are waterbirds.The most recorded birds were classified as residents. All of the birds were recorded or observed easily every day or almost every day, at least at the research sites. Others (8 species) wee categorized as migratory birds. Fourteen species are protected by the Regulation of the Minister of Environment and Forestry, the Republic of Indonesia No. P.92/MENLHK/SETJEN/KUM.1/8/2018, 30 August 2018.

Full textAbstract:
The singing of song birds can form complex signal systems comprised of numerous subunits sung with distinct combinatorial properties that have been described as syntax-like. This complexity has inspired inquiries into similarities of bird song to human language; but the quantitative analysis and description of song sequences is a challenging task. In this study, we analysed song sequences of common nightingales ( Luscinia megarhynchos ) by means of a network analysis. We translated long nocturnal song sequences into networks of song types with song transitions as connectors. As network measures, we calculated shortest path length and transitivity and identified the ‘small-world’ character of nightingale song networks. Besides comparing network measures with conventional measures of song complexity, we also found a correlation between network measures and age of birds. Furthermore, we determined the numbers of in-coming and out-going edges of each song type, characterizing transition patterns. These transition patterns were shared across males for certain song types. Playbacks with different transition patterns provided first evidence that these patterns are responded to differently and thus play a role in singing interactions. We discuss potential functions of the network properties of song sequences in the framework of vocal leadership. Network approaches provide biologically meaningful parameters to describe the song structure of species with extremely large repertoires and complex rules of song retrieval.

Abstract. One hundred and thirty-two 4-weeks old unsexed Anak-2000 broiler strain were used to study the effect of feeder space allowance on agonistic behaviour and growth performance of broilers from weeks 4–8. The feeder space allowance were 2.4 cm/bird, 3.0 cm/bird and 3.6 cm/bird in groups I, II and III. The agonistic behaviour observed included head pecks, steps, pushes, threats and chase during feeding and "non-feeding" periods. There was a decrease in total agonistic behaviour as feeder space per bird increased from 2.4cm/bird to 3.6 cm/bird, both during feeding and non-feeding periods. There was a significant effect (p ≤ 0.05) of feeder space allowance on mean agonistic acts/bird/hour during feeding period being highest in G1 (7.8 acts/bird/hour), and lowest in G3 (4.5 acts/bird/hour). There was no significant effect (p > 0.05) of feeder space allowance on mean agonistic acts/bird/hour during non-feeding period. In G1 and G2, there was a significant effect (p ≤ 0.05) of period of observation on mean agonistic acts/bird/hour being highest in the feeding period and lowest in the non-feeding periods. In G3, there was no significant effect (p > 0.05) of period of day on mean agonistic acts/bird/hour and no significant effect of feeder space allowance on the growth performance parameters measured at p>0.05.

Full textAbstract:
Millions of nocturnally migrating birds die each year from collisions with built structures, especially brightly illuminated buildings and communication towers. Reducing this source of mortality requires knowledge of important behavioral, meteorological, and anthropogenic factors, yet we lack an understanding of the interacting roles of migration, artificial lighting, and weather conditions in causing fatal bird collisions. Using two decades of collision surveys and concurrent weather and migration measures, we model numbers of collisions occurring at a large urban building in Chicago. We find that the magnitude of nocturnal bird migration, building light output, and wind conditions are the most important predictors of fatal collisions. The greatest mortality occurred when the building was brightly lit during large nocturnal migration events and when winds concentrated birds along the Chicago lakeshore. We estimate that halving lighted window area decreases collision counts by 11× in spring and 6× in fall. Bird mortality could be reduced by ∼60% at this site by decreasing lighted window area to minimum levels historically recorded. Our study provides strong support for a relationship between nocturnal migration magnitude and urban bird mortality, mediated by light pollution and local atmospheric conditions. Although our research focuses on a single site, our findings have global implications for reducing or eliminating a critically important cause of bird mortality.

Full textAbstract:
Highway infrastructure and accompanying vehicle noise is associated with decreased wildlife populations in adjacent habitats. Noise masking of animal communication is an oft-cited potential mechanism underlying species loss in sound-polluted habitats. This study documents the disruption of between-species information transfer by anthropogenic noise. Titmice and chickadees broadcast specific calls to alert kin of predator threats, and sympatric vertebrates eavesdrop on these alarm calls to avoid predators. We tested if tufted titmouse alarm call eavesdropping by northern cardinals is disrupted by road noise. We broadcast recorded alarm calls to cardinals in natural areas near and far from highways. Cardinals reliably produced predator avoidance responses in quiet trials, but all birds in noisy areas failed to respond, demonstrating that highway noise is loud enough to disrupt this type of survival-related information via masking or cognitive distraction. Birds in family Paridae are abundant, highly social and vocal residents of woodlands across the Holarctic whose alarm calls are used by many species to mediate predation risks. Our work suggests that communication network disruption is likely to be widespread, and could help explain the pattern of reduced biodiversity near roadways.

Full textAbstract:
Visual signals are crucial for parent–offspring communication, although their functioning has been neglected for nocturnal birds. Here, we investigated parental preference for nestling coloration in nocturnal conditions—a question hitherto unexplored—in a nocturnal raptor, the scops owl ( Otus scops ). We assessed how parents allocated food during the night in relation to a manipulation of ultraviolet (UV) reflectance of the cere (skin above the beak) of their offspring. Reflectance of the cere shows a marked peak in the UV part of the spectrum, and location of the UV peak is related to nestling body mass (i.e. heavier nestlings have a UV peak at lower wavelengths). We found evidence of parental bias in favour of lighter offspring: UV-reduced nestlings gained more weight during the night than their control siblings. This study provides the first experimental evidence of the use of visual cues for parent–offspring communication in a nocturnal bird.

Abstract This article shows how language materiality is conceptualized through an ethnolinguistic analysis of the representation of the owl as an indication of human-bird relationships. This approach enables addressing the multiple relations between birds and speakers and their perception of the environment as these are reflected in language, folklore and rituals. This research is related to such discourses as “language”, “materiality” and “environment” and is based on a case study of the Mari, a Finno-Ugric people who live in central Russia and still adhere to their folk religion. First, it sets out the Mari names which are used for birds of the owl family, then it shows how the terminology has changed due to the emotional side of humanity, and how terms express things in metaphorical way. Next, the article focuses on how the bird (owl) can be a source of positive or negative information with regard to auguring the future and how the symbolic use of birds in rituals and magical actions contributes to co-creating landscapes between human and non-human agencies. This study is based on extensive linguistic, folklore and ethnographic material, including my own field material.

Full textAbstract:
On April 10, 2019, a global crisis began outside Ethiopia’s capital, Addis Ababa. A Boeing 737 Max 8 airplane owned and operated by Ethiopian Airline crashed in the desert killing all on board. The accident mimicked a six months old Lion Air flight 610 which happened in Indonesia and claimed the lives of all crew and passengers. Together, these accidents claimed the lives of 346 people and have been noted as one of the dark days in modern aviation history. Subsequently, the aviation world grounded all Boeing 737 Max aircrafts amid safety concerns. This brought severe public criticism to Boeing, America’s biggest manufacturing exporter, relative to the safety of its flagship airplane. Applying crisis communication theories such as Apologia, SCCT, and Image Restoration, the study finds that these strategies together with other public relations strategies could support public perception in favor of Boeing.

Full textAbstract:
Denna studie är ett kandidatarbete utfört på kandidatprogrammet Grafisk design och kommunikation vid Linköpings universitet. Studien är en kvalitativ designfallstudie som genomförts i samarbete med dansgruppen Pussytiv Dance, där en installation innehållande dans och rörlig bild har utvecklats. Studien syftar till att undersöka hurvida samhällsdebatten om offentlig amning kan kommenteras genom rörlig bild som en del av denna installation. Installationen visades på Feministisk Festival i Malmö 10 juni 2016. Målet med installationen är att väcka tankar, känslor och skapa diskussion om det samtida samhällsklimatet kring offentlig amning i syfte att bidra till en attitydförändring. Debatten om amning på offentlig plats präglas av frågor som rör paradoxen kring kvinnans bröst som sexuellt objekt och matbärare. Samhällets normer leder till att kvinnor känner sig obekväma att amma på offentlig plats, där det även har skett diskriminering i samband med amning. Dessa normer var önskvärda att ifrågasätta genom installationen. Studien kom fram till att det var möjligt att kommentera samhällsdebatten om offentlig amning genom rörlig bild som en del i en dansinstallation. Det kom även fram till att installationens kommunikationsmål nåddes och att installationsformen, dans och rörlig bild, är en effektiv form för att få mottagaren att reflektera över sina egna normer, vilket öppnar upp möjligheten att ändra på invanda attityder.

Full textAbstract:
This dissertation presents three separate studies exploring parents’ perceptions and recommendations for communicating with their third, fourth, and fifth grade children about human sexuality. First, a systematic literature review is presented summarizing past qualitative studies completed in the United States focusing on parents with children aged 18 years and under. This review summarizes (1) demographic information of parents from past studies, (2) perceived communication barriers experienced by parents regarding sexuality communication, and (3) perceived communication facilitators experienced by parents regarding sexuality communication.
Second, noting the lack of research within a specific population of parents in the United States, a naturalistic study of parents with children in the third, fourth, and fifth grade is presented. Utilizing an emergent design, one-on-one interviews were conducted with 20 parents living in a town in central Texas. By coding collected data, a thematic analysis was used to summarize emergent themes. Themes included techniques parents utilized to have parent-child conversations about sexuality and discussed topics. Although different techniques and topics were raised, parents showed overall inconsistency in experiences or past discussions.
Third, using data from the same 20 interviews, themes emerged from parents regarding recommendations. These included the recommendations that a booklet with age appropriate information on sexuality topics be developed for parents and parent workshops or classes covering age appropriate sexuality knowledge as well as techniques to use in parent-child communication be offered. Schools were the recommended source for these resources. Parents also shared feedback on the newly released National Sexuality Education Standards. Comparing past parent-child conversations on sexuality topics to the NSES, certain topics were discussed yet inconsistency was shown. In addition, parents disagreed on specific standards including those pertaining to the functions of reproductive parts, reproduction, and same sex orientation.
Implications of this study are that parental resources are needed to help parents communicate with their children about sexuality beginning at a young age. And, for those resources already existing, including workshops, books, and on-line sources, parents need to be made aware of their existence. In addition, future research is needed to explore if younger children are learning from parent-child conversations about sexuality.

Full textAbstract:
The tawny frogmouth is one of Australia’s most intriguing and endearing birds. Written by award-winning author Gisela Kaplan, one of Australia’s leading authorities on animal behaviour and native birds, this second edition of Tawny Frogmouth presents an easy-to-read account of these unique nocturnal birds, which can be found across almost the entire continent. Fully revised and updated throughout, this book combines 20 years of systematic observation with published research and information from regional surveys, and represents the most comprehensive single study ever conducted on tawny frogmouths.
We learn that tawny frogmouths are very affectionate, have close bonds with lifelong partners, scream like prowling tomcats when distressed, fight with lightning speed and defend nest sites from reptilian predators by mobbing and spraying pungent faeces at them. Uncompromising male fights are contrasted with the touching gentleness of males as fathers. We also learn how resilient and unusual tawny frogmouths are in the way they cope with heat and cold and scarcity of water, sit out danger, and use a large variety of food items.
This fascinating book has a wide appeal to bird lovers, amateur ornithologists and naturalists, as well as those with a scientific or professional interest in native birds, their communication, emotions and skills.

Nigeria-based Christian bodies have over the years politically acclimatized, secularizing and commoditizing their activities and discourse. This is reflected in their communications which most often tap into controversial sources such as politics and power. In effect, the two phenomena of politics and power today represent dominant themes and forms of baits in religious persuasive communications. A case in point is the Christian advertising discourse that, in many complex ways, often deploys the concept of power, sometimes with political undertones. Using semiotics and the content analysis of a corpus of over 500 advertising copies generated by 50 different charismatic churches based in four South-Eastern Nigerian cities, this chapter critically examines the various ways in which the concept of (socio-political) power is used in advertising messages designed by Nigerian Christian organizations. The study also examines how this concept of power is used outside the spiritual realm in a bid to promise various forms of political and economic prosperity to gullible Nigerian masses.

Although many critical scholars in the West have acknowledged the unequal distribution of power across the globe, few have attempted to undertake systematic research on how countries in the periphery are drawn into the neo liberal project of globalization under the discourse of Knowledge Based Economy (KBE) and how this process effects policy formation regarding ICTs. The purpose of this chapter is to analyze Knowledge Based Economy (KBE)/Information Society (IS) discourses in constructing global dependency relations on ICT policies within the context of Turkey. These dependency relations have many aspects including a discursive one. In this study, the focus will be on policy documents to better understand the overall discourse, social processes and structures which have been reflected in, represented and constructed or constituted by this discourse to theorize and transform. Four documents were selected as representing the hegemonic center, one produced by the World Bank and three policy documents from the European Union. Additionally three documents which represent the Turkey context were selected. Upon examination two documents were found to be counter hegemonic and the other supported the hegemonic visions of the World Bank and the European Union. Turkey has signed a number of stand-by agreements with the IMF/World Bank due to economic crisis over the last twenty years and Turkey’s bid to become a full member of the European Union necessitated alignment of legal infrastructure and domestic policies. The chapter also explains how the dependent discourses reversed ICT and network policy formation based on local capabilities and local needs.

E-Rate is a funding source established by the Federal Communications Commission (FCC) on May 7, 1997. The purpose of the funding is to ensure Universal Telecommunications Service is available to public schools and libraries. Telecommunication services include voice, data, internet, and classroom learning solutions. Schools and libraries apply for E-Rate assistance when adding telecommunications infrastructure upgrades. If approved, applicants are required to follow and maintain strict accounting procedures and any red flags raised during the continual compliance assurance process can immediately stop funding until a resolution is found. The potential for a good deal of tension among education stakeholders exists when E-Rate funding is put on hold due to such audit questions. Such experiences are common as detailed in this case study.

Full textAbstract:
Abstract The widespread use of sodium aluminosilicate glass in many critical applications due to its hardness, weight, density and optical properties (transparency, dielectric etc.), instead of metals or plastics has become common in recent years. However, glass which is known to be a brittle material has its own vulnerability to fracture. Processes such as heat treatment (heat tempering) or chemical strengthening, through ion-exchange have been deployed to create residual stress profile on the glass, in a bid to improve its strength for applications such as in the automobile windshield design, consumer electronics mobile communication devices e.g. smartphones and tablet etc. However, failure still occurs which is mostly catastrophic and expensive to repair. Therefore, understanding, predicting and eventually improving the resistance to damage or fracture of chemically strengthened glass is significant to designing new glasses that would be tougher, while retaining their transparency. The relationship between the glass residual stress parameters, compressive stress (CS), depth of layer (DOL), center tension (CT) and fracture strength was investigated in this study using a grit particle blast plus ring on ring test method, based on IEC standard for retained biaxial flexural strength measurements. This technique can be used to measure both the surface and edge fracture strength of the glass. Preliminary results showed that for a reasonable level of CS, and CT, high DOL are beneficial to resisting fracture due to severe surface damage, while a high CS and low CT are beneficial to resisting fractures due to shallower flaws. The correlation of critical stress intensity factor versus DOL and CT for various level of CS were also determined and discussed. These results provide a valuable piece of information in the design of a more robust glass in engineering applications.

Full textAbstract:
In November 2013 the revised ASME PCC-1 “Guidelines for Pressure Boundary Bolted Joint Assembly” were published including Appendix A, “Training and Qualification of Bolted Joint Assembly Personnel.” This Appendix outlines a training, examination and qualification system for ensuring a consistent level of knowledge and experience for bolting assemblers and specialists working on bolted flange joint assemblies. The ultimate objective is a mobile workforce capable of bolting ASME plant with a minimum performance standard safely and with no subsequent leaks. Major operators and contractors involved in oil and gas, petrochemical and power generation, or any industry that uses bolted flange joint assemblies, can benefit from PCC-1. Benefit recognition has begun with operators now specifying PCC-1 compliance in their procedures and bid packages. However, nearly three years after the introduction of Appendix A the number of Qualifying Organizations approved to deliver the program and individuals qualified via these programs remains stubbornly small in comparison with other programs and insufficient to meet the future safety demands of the industry or the objective of PCC-1 and Appendix A. This technical paper reviews key elements of Appendix A, compares Appendix A with other international qualifications and suggests recommendations intended to increase recognition and compliance with these guidelines. The recommendations and expected benefits follow from an extensive review of work by other organizations and published data concerned to reduce recorded leaks from bolted joints, including: a) Implementation lessons learned from a Qualifying Organization and Review Organization. b) Current international qualifications and the differing routes to achieve each qualification including: 1) ASME PCC-1 Appendix A Training and Qualification of Bolted Joint Assembly Personnel. 2) European standard EN1591-4 Qualification of personnel competency in the assembly of the bolted connections of critical service pressurized systems. 3) Engineering Construction Industry Training Board (ECITB) Mechanical Joint Integrity (MJI) technical training standards and Step Change in Safety Mechanical Joint Integrity Route to Competence Guidance 4) Additional country specific qualifications c) Program effectiveness study of the Engineering Construction Industry Training Board (ECITB) Mechanical Joint Integrity (MJI) program and the Step Change in Safety Hydrocarbon Release (HCR) model set up to achieve leak reduction in the UK North Sea sector. Finally, the paper will conclude with outlining the benefits to be gained globally through standardization of international qualification programs to enable true portability including: a) The need to increase the number of auditable Qualifying Organizations able to deliver the program, qualify individuals and engage operator/contractors in the process. b) Importance of effective communication and summary of the guidelines.

Full textAbstract:
Endothelium is important to maintain blood fluidity preventing coagulation. Glycosaminoglycan in the endothelial cell plasma membrane has been thought to prevent activation of blood coagulation. Heparin-like compound, which is a potent anticoagulant activity, has been localized on the surface of the cultured endothelial cells. Anticoagulant action associated with thrombomodulin, which is present in endothelial cells, is another mechanism to provide hemostatic nature of endothelial cells.We wondered whether any other intracellular protein(s) is involved in coagulation. We looked for such a protein(s) in cultured bovine aortic endothelial cells. We soon found an anticoagulant activity in the soluble fraction of endothelial cells and it was partially purified. This activity was adsorbed to DEAE-Sepharose and eluted from a gel filtration column in a molecular weight range of 30,000-40,000. However, limited amounts of the cells made it difficult to purify this activity. We then chose human placenta as a substitute source of this protein and have continued the purification of this anticoagulant activity.In this communication, we describe the isolation and characterization of a placental anticoagulant protein, called "PAP", which is silmilar or possible same as the endothelial anticoaguant protein. PAP was purified from the soluble fraction of human placenta by ammonium sulfate precipitation and column chromatography on DEAE-Sepharose, Sephadex G-75, and mono S (Pharmacia). Approximately 20 mg of the protein was purified from one placenta. The purified protein gave a single band by SDS polyacrylamide gel electrophoresis with a molecular weight of 36,500. This protein inhibited both kaolin- and thromboplastin-induced partial thromboplastin times of normal human plasma. It also inhibited the clotting time of platelet-rich plasma induced by factor Xa, but did not affect the thrombin activity of fibrinogen-fibrin conversion. The purified protein completely inhibited the prothrombin activation by reconstituted prothrombinase. The protein neither inhibited the amidolytic activity of factor Xa nor bound factor Xa. This protein specifically bound to phospholipid vesicles (20% phosphatidylserine and 80% phosphatidylcholine) in the presence of calcium ions. These results indicate that PAP inhibits coagulation through the binding to phospholipid vesicles. The study on the amino acid sequence of PAP is in progress in our laboratory. Surprisingly, the sequence analysis of the cyanogen bromide fragments revealed that PAP is a new member of the lipocortin or calpactin family. The sequences of several cyanogen bromide fragments of PAP aligns with the sequences of lipocortin I and II with over 50% identity.Since PAP interacts directly with phospholipid rather than factor Xa, other activation steps in the coagulation cascade, in which phospholipid is involved, are pro^|bly affected by PAP. These reactions are the activation of factor X by a complex of factor IXa-factor VIIIa-phospholipid-Ca++ and the activations of factor X and factor IX by a tissue factor-factor VIIa-Ca++ complex.Reutelingsperger et. al,, have reported the isolation of a novel inhibitor from arteries of human umbilical cord. This protein inhibited the prothrombin activation by prothrombinase. The authors proposed that the inhibition mechanism of this inhibitor was a competition with factor Xa for binding to phospholipid. This protein is very similar to PAP as to the mode of inhibition. The molecular weight of this inhibitor is 32,000, which is slightly smaller than PAP. With the limited chemical characterization of this protein, presently it is difficult to identify this inhibitor with PAP.At the present time, the physiological role and origin of PAP is not known. PAP may originate from the endothelium of placenta, because we have detected a PAP-like anticoagulant activity in bovine aortic endothelial cells. This activity and PAP were quite alike in the purification up to the gel filtration step. If PAP antibody recognizes the antigen in the endothelial cells, it is interesting to see whether PAP localizes on the surface or inside the cells. Nevertheless, if PAP is present in the endothelial cells, it may play an important role to maintain the hemostatic nature of endothelium. PAP may bind phospholipid components at injured sites, before coagulation factors come in contact with lipid components and initiate thrombolytic events.
