Bien que l’industrie du livre soit un objet de recherche aussi bien en France qu’en Allemagne, les travaux qui lui sont dédiés traversent rarement le Rhin. Cet article propose une approche franco-allemande de l’étude des mutations actuelles de cette industrie. Deux perspectives sont ici adoptées : celle des sciences de l’information et de la communication (SIC), et en particulier celle de la théorie des industries culturelles, et celle de la Buchwissenschaft, une discipline allemande entièrement consacrée au livre. Les deux approches sont présentées dans cet article, qui conclut en leur complémentarité et en la pertinence de leur utilisation dans le contexte de travaux portant sur les mutations de l’industrie du livre. Although the book industry is a subject of research in both France and Germany, research on it rarely crosses the Rhine. This article proposes a Franco-German approach to the study of current changes in this industry. Two perspectives are adopted here: that of the information and communication sciences (SIC), and in particular that of the theory of cultural industries, and that of Buchwissenschaft, a German discipline entirely devoted to books. The two approaches are presented in this article, which comes to the conclusion that they complement each other and that their use is relevant in the context of works on the mutations of the book industry.

Digitalization is both a major cause of the challenges now faced by several media industries and a source of their potential solutions. Within the book and newspaper industries, the value of the physical product is about to be surpassed by that of digitally delivered content, disrupting the distribution system that these industries have relied on for many decades. In particular, digital distribution has radically changed the way in which consumers engage in unpaid and paid media consumption. Anchored in the notion of disruptive innovation, and more specifically related to the idea of distribution as disruptive technology, our study investigates Generation Z’s unpaid and paid consumption of digital books and online local newspapers. Drawing on two Norwegian audience surveys, we find that both industries involve at least one disruptive actor. Generation Z relies heavily on Facebook as a distribution channel for news. Pay-walls have a negative effect on the usage of paid online local news, despite the belief that paywalled news is better than free news. In the Norwegian book industry, paper books still have a very strong position among Generation Z. Audiobooks have greater usage than e-books, and we conclude that the real disruptive actor in the Norwegian book industry is the streaming of audiobooks by actors such as Storytel.

Based on the hypothesis that there is no strictly mesoanalytical and mesoeconomic research on the book and its industry, this article systematises the most relevant academic and professional bibliographic production (1958-2021) relating to the two objects of study, organising it into six analytical perspectives – four consolidated and two propositional. It then organises the stated production within each of these perspectives, to subsequently identify their most significant contributions for future mesoanalytical and mesoeconomic research. Finally, the article validates the hypothesis put forth. Partiendo de la hipótesis de la no existencia de investigaciones estrictamente mesoeconómicas y mesoanalíticas del libro y su industria, este artículo sistematiza la producción bibliográfica académica y profesional (1958-2021) más relevante relacionada con los dos objetos de estudio, organizándola en seis perspectivas de análisis, cuatro consolidadas y dos propositivas. Seguidamente clasifica dicha producción en el interior de cada una de esas perspectivas, para posteriormente identificar sus aportaciones más significativas en el marco de futuras investigaciones mesoeconómicas y mesoanalíticas. Finalmente, el artículo valida la hipótesis propuesta.

How can the political decision, as an element of public administration, fully and quickly solve the social problem about the values? The authors of the article suggest to consider similar experience in the field of education and culture on the example of the Saint-Petersburg International Book Fair as the element of the region strategy and as the method of solving social, marketing and image tasks.

We study the fiction publishing sector using the top ten annual best-sold novels in the United States during the whole 20th century. We show that the number of bestselling women dropped sharply between 1950 and 1980 and that during the 20 last years of the century it was much more difficult for new writers to enter the list. Though we cannot show that this is caused by the very important concentration of publishers, the two phenomena are obviously correlated., SCOPUS: ar.j, info:eu-repo/semantics/published

The current investigation deals with how chemically activated carbon derived from industrial paper sludge (ACPS) performs on sorptive removal of enrofloxacin (ENF), an antibacterial drug from its water solution. Thermogravimetric (TGA) and proximate analysis of raw paper sludge (RPS) were conducted. ACPS was characterized with proximate analysis, XRD, FT-IR, SEM and BET. The influence of five operational parameters viz. adsorbate concentration (initial), dose of adsorbent, pH, temperature, and contact time on the adsorption of ENF onto ACPS has been conducted using batch experiments. The process of adsorption was optimized through ANN (artificial neural network) in addition to RSM (response surface methodology). The maximum percentage removal (95.85%) was achieved at initial ENF concentration 12 mg/g, adsorbent dose 1.2 g/L, contact duration of 18 h and temperature 20 °C. Kinetic data were best fitted into pseudo-second order kinetic model and adsorption equilibrium study indicates that the adsorption process follows Langmuir isotherm model. Adsorption capacity was noted to have a highest value of 44.44 mg/g. A study on thermodynamics of the adsorption process suggests that it exhibits spontaneity, being essentially exothermic. Cost analysis and reusability study confirm that adsorbent produced from industrial paper sludge is cost-effective and reusable. Therefore, ACPS as adsorbent has potency for removing ENF from aqueous solution.

This study investigated the implications of using two grades of limestone from a paper and pulp industry for neutralization of acid mine drainage (AMD) in a pilot sequencing batch reactor (SBR). In this regard, two grades of calcium carbonate were used to neutralize AMD in a SBR with a hydraulic retention time (including settling) of 100 min and a sludge retention time of 360 min, by simultaneously monitoring the Fe(II) removal kinetics and overall assessment of the AMD after treatment. The Fe(II) kinetics removal and overall AMD treatment were observed to be highly dependent on the limestone grade used, with Fe(II) completely removed to levels lower than 50 mg/L in cycle 1 after 30 min using high quality or pure paper and pulp limestone. On the contrary, the other grade limestone, namely waste limestone, could only achieve a similar Fe(II) removal efficiency after four cycles. It was also noticed that suspended solids concentration plays a significant role in Fe(II) removal kinetics. In this regard, using pure limestone from the paper and pulp industry will have advantages compared with waste limestone for AMD neutralization. It has significant process impacts for the SBR configuration as it allows one cycle treatment resulting in a significant reduction of the feed stock, with subsequent generation of less sludge during AMD neutralization. However, the use of waste calcium carbonate from the paper and pulp industry as a feed stock during AMD neutralization can achieve significant cost savings as it is cheaper than the pure limestone and can achieve the same removal efficiency after four cycles.

In traditional publishing, female authors' titles command nearly half (45%) the price of male authors' and are underrepresented in more prestigious genres, and books are published by publishing houses, which determined whose books get published, subject classification, and retail price. In the last decade, the growth of digital technologies and sales platforms have enabled unprecedented numbers of authors to bypass publishers to publish and sell books. The rise of indie publishing (aka self-publishing) reflects the growth of the "gig" economy, where the influence of firms has diminished and workers are exposed more directly to external markets. Encompassing the traditional and the gig economy, the book industry illuminates how the gig economy may disrupt, replicate, or transform the gender discrimination mechanisms and inequality found in the traditional economy. In a natural experiment spanning from 2002 to 2012 and including over two million book titles, we compare discrimination mechanisms and inequality in indie and traditional publishing. We find that indie publishing, though more egalitarian, largely replicates traditional publishing's gender discrimination patterns, showing an unequal distribution of male and female authors by genre (allocative discrimination), devaluation of genres written predominantly by female authors (valuative discrimination), and lower prices within genres for books by female authors (within-job discrimination). However, these discrimination mechanisms are associated with far less price inequality in indie, only 7%, in large part due to the smaller and lower range of prices in indie publishing compared to traditional publishing. We conclude that, with greater freedom, workers in the gig economy may be inclined to greater equality but will largely replicate existing labor market segmentation and the lower valuation of female-typical work and of female workers. Nonetheless, price setting for work may be more similar for workers in the gig economy due to market competition that will compress prices ranges.

Little is known about the epidemiology of contact dermatitis (CD) in print machine operators (PMOs).The aims of this study were to estimate the prevalence of CD and characterize clinically relevant and occupationally related allergens among PMOs undergoing patch testing.This was a retrospective cross-sectional analysis of the North American Contact Dermatitis Group data from 1998 to 2014.Of 39,332 patch-tested patients, 132 (0.3%) were PMOs. Among PMOs, most were male (75.0%) and white (92.4%). The majority were printing press operators (85.6%). The most frequent sites of dermatitis were hands (63.6%), arms (29.5%), and face/scalp (24.2%). More than half had an occupationally related skin condition (56.1%). Final diagnoses were most commonly allergic CD (58.3%) and irritant CD (33.3%). Cobalt (20.8%), carba mix (12.5%), thiuram mix (8.3%), and formaldehyde (8.3%) were the most frequent occupationally related allergens. The top allergen sources included inks (22.9%), gloves (20.8%), and coatings/dye/copy/photographic chemicals (14.6%).Allergic CD, irritant CD, and involvement of exposed body areas were common among PMOs. Common allergens included rubber accelerators, metals, and preservatives.

Removal batch assays of phosphates from a synthetic wastewater (SWW) and a pulp and paper mill wastewater (PPWW) with two forestry biomass ashes were performed. The supernatants were not only chemically characterized but also the ecotoxicity was determined using two organisms: Vibrio fischeri and Artemia franciscana. The addition of fly ash and bottom ash to the SWW in solid/liquid (S/L) ratios of 3.35 and 9.05 g L−1, respectively, achieved removal percentages of phosphates >97% for both ashes. The addition of fly ash and bottom ash to the PPWW in S/L ratios of 34.45 and 46.59 g L−1, respectively, yield removal percentages of phosphates >90% for both ashes. According to the results of the Langmuir and Freundlich isotherms, the removal of phosphates from the SWW was mainly explained by surface removal mechanisms, while the removal from the PPWW was partially explained by multi-layer mechanisms. The supernatants resulting from the treatment of SWW and PPWW with both biomass ashes did not present acute ecotoxicity.

Des de fa poc més d’una dècada, autors, teòrics i periodistes parlen de la novel·la gràfica com a àmbit en el qual el còmic, per fi, ha aconseguit un nivell de qualitat literari que obri, així, les portes de la legitimació cultural. En aquest article ens allunyarem de les perspectives d’estudi més comunes i qüestionarem la relació entre còmic, novel·la gràfica i literatura. Des de l’anàlisi de la indústria del còmic espanyola, parant especial atenció a la distribució i als canals de venda, buscarem indicis de si, tot i no ser literatura, la novel·la gràfica està propiciant una normalització de la indústria del còmic espanyola com a subsector de la indústria editorial. Only since just over a decade ago, authors, scholars and journalists have been talking about the graphic novel as a field in which the comic medium has finally achieved literature’s standard quality, opening the doors of cultural legitimization. In this article we will look at the relationship between comics, graphic novels and literature from a very different perspective. By the analysis of the Spanish comics industry, and paying particular attention to the distribution channels, we will look for indications of whether, despite not being considered literature as such, the graphic novel is leading to a normalization of the comic industry in Spain as a subsector of the book industry.

A publicação em revistas de acesso aberto cresceu expressivamente nos últimos anos. As publicações de acesso fechado, por sua vez, têm custo de acesso cada vez mais elevado, por se beneficiarem de um modelo econômico peculiar: o trabalho relevante e os insumos essenciais são entregues gratuitamente a fornecedores que contam com um mercado cativo, praticamente sem concorrência. O mercado editorial é altamente oligopolizado, característico de indústrias que trabalham com o regime de copyright. Isso contribui para a elevação dos preços de seus produtos. Políticas mandatórias de acesso aberto, como a determinada pela agência National Institutes of Health, constituem-se em ameaça a esse modelo de negócios e são enfrentadas pela indústria em várias frentes, incluindo a passagem de legislação para sabotar tais iniciativas. O objetivo deste comentário foi apresentar alguns aspectos principais desse enfrentamento e sugerir possíveis estratégias de incremento da publicação de acesso aberto em nosso meio.

This article describes a study on the viability of using waste from the paper industry: biomass boiler ash and green liquor dregs to fabricate mortars and concretes. Both types of ash were characterized by obtaining their chemical and mineralogical composition, their organic matter content, granulometry, adsorption and other common tests for construction materials. Seven different mortars were fabricated, one for reference made up of cement, sand, and water, three in which 10, 20, or 30% of the cement was replaced by biomass ash, and three others in which 10, 20, or 30% of the cement was replaced with dregs. Test specimens were fabricated with these mortars to conduct flexural and compression tests. Flexural strength is reduced for all the mortars studied. Compressive strength increases for the mortars fabricated with biomass ash and decreases for the mortar with dregs. Finally, 5 concretes were made, one of them as a reference (neither biomass ash nor dregs added), two of them with replacements of 10 and 20% of biomass ash instead of cement and another two with replacements of 10 and 20% of dregs instead of cement. The compressive and tensile splitting strength increase when a 10% of ash is replaced and decrease in all the other cases. The modulus of elasticity always decreases.

This paper explores the structure of the book publishing industry post-digitalisation. We argue that the introduction of successful e-book readers has belatedly given digitalisation the characteristics of a disruptive technology by making self-publishing a serious option for authors. This has been supported by the entry of new types of intermediaries and the strengthening of others. These changes have reduced the overall complexities for an author to get a book self-published. As a result, a larger share of the surplus from the book industry is likely going to authors, explaining the significant increase in the supply of books. The potential over-supply of books has created a new problem by making consumer search more difficult. We argue that digitalisation has shifted the potential market failure from inadequate supply of books to asymmetric information about quality. It remains to be seen whether the market will provide appropriate intermediaries to solve the associated asymmetric information problem and, if not, what appropriate interventions should be contemplated.

We show that books for general audiences are similarly priced internationally but textbooks are substantially more expensive in the United States. We argue that cost factors cannot explain this phenomenon and discuss several demand-side explanations. © 2006 Elsevier B.V. All rights reserved. 95 91 95 91-95

The article presents literature that analyses recent changes in the book industry: concentration of publishing firms, commercialisation, and introduction of new digital technologies. The article pays special attention to John B. Thompson’s Books in the Digital Age, which is criticised for having an externalist and one-sided analysis of the role technology plays in shaping the book and the book business. Bokbransjen er endret: Mange forlag er samlet i store konsern, kommersialiseringen har økt, og produksjon og omsetting av bøker er preget av digitale teknikker og Internett. I denne artikkelen vil jeg presentere litteratur som analyserer disse omveltningene, samt holde frem norske utredningsprosjekter gjort på digital lesing. Jeg vil særlig problematisere John B. Thompsons analyse av bokens digitalisering, slik han fremstiller denne i verket Books in the Digital Age.

For the paper industry, the disposal and management of the yielded sludge are a considerable challenge. In our work, the paper mill sludge-derived magnetically separable heterogeneous catalyst (PMS-Fe-380) was prepared easily through a facile synthesis method. The morphology and structure of PMS-Fe-380 were fully characterized by means of X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and Brunauer-Emmet-Teller analysis. The catalytic activity of PMS-Fe-380 was evaluated by degradation of Methylene Blue (MB). The reusability and stability of PMS-Fe-380 were evaluated in five repeated runs, which suggested that PMS-Fe-380 manifested excellent stability of catalytic activity. Moreover, leaching tests indicated that the leached iron is negligible (

The biomass content of material from pulp and paper production (a mixture of waste and paper and thin layer packaging plastics) is determined by the adapted balance method. This novel approach is a combination of combustion elemental analysis (CHNSO) and a data reconciliation algorithm based on successive linearisation for evaluation of the analysis results. It also involves less effort and expense than conventional procedures. However, the CHNSO technique only handles small mass amounts (few hundred milligrams), so cryogenic impact milling was applied for particle size reduction below 200 µm in order to generate homogeneous, representative analysis samples. The investigation focuses on the parameters biogenic content as a percentage of the total mass xB and xBTC, which is the biomass stated as a fraction of the total carbon value. The results are within 1%–5% of the data obtained by the reference methods, namely the selective dissolution method and 14C- method. Additionally, advantages and drawbacks of the adapted balance method in comparison with standard methods are discussed, showing that the adapted balance method is a method to be considered for the determination of biomass content in solid recovered fuels or similar materials.

A 90 day study was conducted to evaluate the efficiency of an exotic earthworm species (Eudrilus eugeniae) for decomposition of different types of organic substrates (mixed liquor suspended solids, cow dung and leaf litter) into valuable vermicompost. Mixed liquor suspended solids (MLSS) and leaf litter (LL) were mixed with cow dung (CD) in eight different ratios with three replicates for each treatment. All vermibeds expressed a significant decrease in pH, organic carbon, C:N ratio and an increase in total nitrogen, phosphorus and potash. Overall, earthworms could maximize decomposition and mineralization efficiency in bedding with lower proportions of MLSS. Maximum value for earth worm zoo mass and higher concentration of nutrient content was observed in CD + MLSS + LL in 1:1:2 ratios. Earthworm mortality tended to increase with increasing proportion of MLSS and maximum mortality in E. eugeniae was recorded for MLSS treatment alone. Results indicate that vermicomposting might be useful for managing the energy and nutrient of MLSS on a low-input basis. Products of this process can be used for sustainable land restoration practices.

The conventional biological treatment methods employed in the pulp and paper industries are not effective in reducing the colour and chemical oxygen demand (COD). The white-rot fungi are reported to have the ability to biodegrade the lignin and its derivatives. This paper is focused on the biological treatment of pulp mill effluent from a bagasse-based pulp and paper industry using fungal treatment. Experiments were conducted using the white rot fungus, Trametes versicolor in shake flasks operated in batch mode with different carbon sources. The decolourisation efficiencies of 82.5% and 80.3% were obtained in the presence of 15 g/L and 5 g/L of glucose and sucrose concentrations respectively with a considerable COD reduction. The possibility of reusing the grown fungus was examined for repeated treatment studies.

Background In 1998, ICPC-2 was published as a book. In the process of translating the book, and preparing an electronic version of chapter 10 (the actual classification), ICPC-2 proved to contain many errors and inconsistencies. Particularly, major problems were identified in the conversion between ICPC-2 and ICD-10, which could lead to major errors when used in electronic patient records. Objectives We prepared an electronic version of chapter 10 of ICPC-2, ICPC-2-E, with all necessary corrections, to be published on the Oxford University Press web site as a part of this article. Methods Errors and inconsistencies were redressed, including particularly those in the con-version structure with all consequences on the level of inclusion and exclusion criteria, through a process of careful checking. Results and conclusion ICPC-2-E, the electronic version of chapter 10 of ICPC-2, is specifically to be used in an electronic patient record and for research purposes. It is to be used together with the first nine chapters of ICPC-2, since the book is indispensable to make a correct use of ICPC.

Based on the physical and chemical properties as well as calorific values of pulp sludge and textile sludge, this study investigates the differences between manufacturability, relationship between extrusion pressure and formability, as well as stability and combustion behaviors of extruded sludge-derived fuel briquettes (ESBB) and cemented sludge-derived fuel blocks (CSBB). The optimum proportion and relevant usage ESBB policies are proposed as well. Experimental results indicate that a large amount of water can be saved during the ESBB manufacturing process. Additionally, energy consumption decreases during the drying process. ESBB also has a more compact structure than that of CSBB, and its mean penetration loading is approximately 18.7 times higher as well. Moreover, the flame temperature of ESBB (624–968 °C) is significantly higher than that of CSBB (393–517 °C). Also, the dry bulk density and moisture regain of ESBB is significantly related to the penetration loading. Furthermore, the optimum mix proportion of ESBB is co-determined by the formability of pulp sludge and the calorific values of textile sludge. While considering the specific conditions (including formability, stability and calorific values), the recommended mix proportion for ESBB is PS50TS50.

Discharging untreated highly acidic (pH4.0), organic and nutrients rich monosodium glutamate wastewater (MW), and highly alkaline (pH10.0) paper-mill wastewater (PW) causes environmental pollution. When acidity of MW neutralized (pH 6.5±0.1) with PW and lime (treatments represented as MW+PW and MW+Lime), then MW may be utilized as a potential source of nutrients and organic carbon for sustainable food production. Objectives of this study were to compare the effects of PW and lime neutralized MW and chemical fertilizers on maize (Zea mays L. cv. Snow Jean) plant growth, yield, nutrients uptake, soil organic matter and humic substances. The field experiment was carried out on maize using MW at 6000 L ha(-1). Impacts of the MW application on maize crop and soil properties were evaluated at different stages. At harvest, plant height, and plant N and K uptake were higher in MW treatment. Leaf area index at 60 days after sowing, plant dry matter accumulation at harvest, and kernels ear(-1) and 100-kernel weight were higher in MW+Lime treatment. Kernel N, P, K, Mn, Fe and Zn, and plant Zn uptake were highest in MW+Lime. Plant Fe uptake, and soil organic matter and humic substances were highest in MW+PW. The MW+PW and MW+Lime treatments exhibited comparable results with chemically fertilized treatment. The MW acidity neutralized with lime showed positive impacts on growth, yield and nutrients uptake; nevertheless, when MW pH neutralized with PW has an additional benefit on increase in soil organic matter and humic substances.

[Resumen] En un nuevo escenario globalizado, los roles de los agentes tradicionales de la organización de la información en bibliotecas han tendido a converger con aquellos provenientes de la industria del libro, bajo la presunción de que en su mayor parte las prácticas tradicionales bibliotecarias no son válidas ante esta nueva situación. El presente trabajo analiza la naturaleza e implicaciones para las bibliotecas de los vínculos existentes entre los agentes provenientes de la industria de libro y los organismos responsables de los principales sistemas de organización de la información bibliotecarios, tanto en un ámbito internacional como en el caso concreto de España. Algunos de los agentes cuyos discursos han sido analizados incluyen OCLC, el Consorcio de la CDU, BISG, BIC, EDItEUR, DILVE, Google y Amazon, concluyéndose que existe una incursión y colaboración entre uno y otro sector que se materializará en un aumento de la universalidad y homogeneización de unas prácticas de organización de la información en bibliotecas en las que no se tienen en cuenta la naturaleza y características específicas de las diferentes comunidades y contextos. [Abstract] In a new globalized scenario, the traditional activities of information organisation agents in libraries have tended to converge with those from the book industry, under the presumption that most traditional library practices are not adequate for the new globalized situation. This article analyzes the nature and consequences for libraries of the links between agents from the book industry and the organizations in charge of the main library information organization systems, both at an international level and in Spain. Some of the agents whose discourses were analyzed include OCLC, the UDC Consortium, BISG, BIC, EDItEUR, DILVE, Google and Amazon. We conclude that there is evidence of an incursion of book industry practices into the information organisation practices of OCLC and that collaboration between both sectors will result in an increase in universality and homogenization in library information organization practices without consideration for the nature and specific characteristics of the library and how it differs from the bookstore.

In the early 1830s, the Philadelphia publisher Henry H. Porter rapidly published five journals, six books, and an almanac, works having a particular emphasis on health and personal hygiene. Porter’s health publications linked the traditional message about the importance of personal hygiene to health to the messages conveyed by the flourishing American reform movements at the time, and his Journal of Health was among the first American medically oriented periodicals published for the layperson. Yet Porter did not survive in the intensely competitive and financially unstable book trade. This study examines Porter’s health publications, attempting to explain why he chose to publish what he did, the message(s) his works contained, the audience(s) he tried to reach, and the failure of his business.

År 2012 är distribution av litteratur via internet inte längre en framtidsvision, utan ett etablerat format vid sidan av traditionella format som exempelvis pocketboken, den inbundna boken och ljudboken (AAP 2011; Amazon 2011; PaidContent 2011). Men den digitala tekniken etablerar inte enbart ett nytt format, utan förändrar också grundförutsättningarna för litterära konstformer och marknader. Detta kapitel behandlar en betydelsefull aspekt av denna förändring, nämligen hur den digitala tekniken påverkar relationen mellan läsare och författare och ökar läsarens inflytande över den kreativa processen. I den digitala tidsåldern är det möjligt att skapa berättelser online i en interaktiv process som involverar både läsare och författare. Kapitlet presenterar modeller för hur sådan “samproducerad e-litteratur” förändrar marknaden för litteratur och hur den påverkar den traditionella litteraturen.

When becoming involved in the production of artwork for book publications the medical artist must interact and work with publishers through whom authors' instructions are conveyed. Procedures and job titles vary from one publisher to the other and misunderstandings can lead to costly mistakes. From a typical publishing situation a common approach to medical artwork preparation for book publication is described that will prepare the medical artist to work in close cooperation with the publishing team.

An outbreak of “humidifier fever” affected 16 (57%) of 28 workers in a print shop. The most common symptoms were myalgia, chills or subjective fever, and cough. Illness began 5–13 hours after entering the workplace, and lasted 2–24 hours. A humidifier in use the day of the outbreak was found to be contaminated with fungi, amebae, and Gram-negative bacteria. The risk of illness was highest for those who had been on the job 3 months before the outbreak, a time when the humidifier was in constant use. Serologic studies of print shop workers showed positive reactions to extracts of organisms isolated from the humidifier, but could neither distinguish ill from well workers, nor identify causative organisms. The presence of endotoxin-producing bacteria and the clinical syndrome are consistent with an organic dust toxic syndrome. Previous exposure appeared to be the major risk factor for illness. © 1993 Wiley-Liss, Inc.

The cytological state of nasal and oral mucosae in the children and adolescents living in the town of Koryazhma was evaluated at the schools located differently from the Kotlas pulp-and-paper mill (PPM). All the Kozyazhma children under examination were found to have an increased epithelocytic alteration index, which is likely to suggest cytotoxic exposure, which was shown to a greater extent with the duration of residence at the school more adjacent to the PPM. The first-form pupils from the school locates more closely to the PPM were found to showed a higher index of natural microflora colonization with buccal epitheliocytes and a trend for an increase in the epitheliocytic differentiation coefficient characterizing the high incidence of diseases.

The paper presents the results of studying a lettering-art work relationship in the present-day publications for children and adolescents, as well as their readability. The range of major hygienically significant parameters and techniques of text lettering in the publications has been extended on the basis of the findings. Hygienic classification criteria have been developed for books, journals, magazines, and text-books. The quantitative indicator--the potential risk factor of a specific text-book for the visual system of pupils--has been substantiated.

The etiology of systemic sclerosis, probably multifactorial, is not yet well defined. Among the many endogenous and exogenous factors probably involved, occupational elements may play an essential role. Here we report a cluster of local scleroderma and systemic sclerosis, which occurred in a small group of typography workers exposed to polyvinyl-acetate glues, containing up to 1% of vinyl-acetate. Vinyl acetate exposure has been associated with acidification of the intracellular environment, which is thought to produce cytotoxic and/or mitogenic responses that are the sentinel pharmacodynamic steps toward cancer. Autoantibody production in systemic sclerosis depends upon intracellular acidification. More studies are needed to clarify the relationship between vinyl acetate exposure and scleroderma.

Objectives The aim of this study was to investigate cancer risk among Norwegian workers in the printing industry, particularly lung and bladder cancer. Methods Cancer incidence was investigated from 1953 through 1998 in a cohort of 10 549 male members of a trade union in the printing industry in Oslo and nearby areas. Rates from the region, were used to calculate standardized incidence ratios (SIR) separately for the skilled and unskilled workers. Smoking data from a sample of the cohort were utilized for evaluating the risk estimates of smoking-related cancers. Specific exposure data were not available. Results Among the skilled workers, significantly elevated risks of cancer of the urinary bladder [standardized incidence ratio (SIR) 1.47, 95% confidence interval (95% CI) 1.19–1.79], liver (SIR 1.92, 95% CI 1.15–2.99), pancreas (SIR 1.46, 95% CI 1.07–1.94) and colon (SIR 1.27, 95% CI 1.05–1.55) were observed, whereas an increased risk of lung cancer in this group was confined to those born before 1910. Among the unskilled workers, there were significantly increased risks of cancer of the mouth, esophagus, stomach, larynx, lung, and all sites. Conclusions The study showed that workers in the printing industry were at increased risk of several types of cancer. In particular the increased risk of bladder cancer among the skilled workers is suggestive of an occupational cause. However, no specific agent could be identified as an occupational carcinogen. The results did not support the hypothesis of a generally increased risk of lung cancer. The risk pattern for unskilled workers may reflect confounding by nonoccupational factors.

In media markets, products are highly differentiated but prices are often bunched at apparent focal points. I use a comprehensive cross-section data set on the German book market to assess whether such focal points are a result of upstream coordination and whether the option to impose resale price maintenance (RPM) played a facilitating role. Therewith, I provide empirical evidence to a long-lasting policy debate. Results suggest that focal prices are used to coordinate competition rather than collusion. Focal prices are mostly lower than expected from hedonic projections. In cases where the decisions on focal pricing and RPM are positively correlated, controlling for endogeneity and a number of other factors, RPM does not seem to facilitate above average focal pricing in particular. ZUSAMMENFASSUNG - (Fixiert, fokal, fair? Buchpreise bei optionaler Preisbindung) Produkte in Medienmärkten sind hochgradig differenziert, Preise sammeln sich jedoch häufig an augenscheinlich fokalen Punkten. Ich verwende einen umfassenden Satz von Querschnittsdaten aus dem deutschen Buchmarkt, um zu untersuchen, ob derartige Fokalpunkte das Ergebnis von Koordination auf der Verlagsseite sind und ob optionale Preisbindung eine begünstigende Rolle dabei spielte. Damit bereichere ich eine langlebige Politikdebatte mit empirischer Evidenz. Die Ergebnisse legen nahe, dass Fokalpreise eher der Koordination von Wettbewerb als Kollusion dienen. Fokalpreise sind meistens niedriger als von hedonischen Projektionen erwartet. In den Fällen, in welchen die Entscheidungen über fokale Preissetzung und Preisbindung positiv korreliert sind, unter Kontrolle des Einflusses von Endogenität und einer Reihe von anderen Faktoren, scheint optionale Preisbindung die Setzung von überdurchschnittlichen Fokalpreisen nicht insbesondere zu begünstigen.

PURPOSE. To describe the health needs presented by workers in a small industrial setting, describe the occupational health nursing (OHN) services provided, and examine the effectiveness of these services. METHODS. Data were abstracted from 491 employee records accumulated over a 7-year service period. Standardized nursing languages were used to describe employee needs and nursing interventions. FINDINGS. Data revealed 1,368 needs were identified and 3,193 nursing interventions were administered. Health-seeking behaviors, knowledge deficit, collaborative problems, risk of infection, and impaired tissue integrity seemed most amenable to change in the context of OHN services. Altered health maintenance was the problem that seemed least amenable to change. CONCLUSIONS. Findings present a dynamic picture of OHN services provided in an OHN program and their effectiveness. Standardized nursing languages were effective and appropriate in describing the health issues managed and interventions applied. PRACTICE IMPLICATIONS. Further use of standardized nursing languages in occupation health can establish core functions and knowledge base.

Ich verwende einen umfassenden Satz von Querschnittsdaten aus dem deutschen Buchmarkt, um zu untersuchen, ob derartige Fokalpunkte das Ergebnis von Koordination auf der Verlagsseite sind und ob optionale Preisbindung eine begünstigende Rolle dabei spielte. Damit bereichere ich eine langlebige Politikdebatte mit empirischer Evidenz. Die Ergebnisse legen nahe, dass Fokalpreise eher der Koordination von Wettbewerb als Kollusion dienen. Fokalpreise sind meistens niedriger als von hedonischen Projektionen erwartet. In den Fällen, in welchen die Entscheidungen über fokale Preissetzung und Preisbindung positiv korreliert sind, unter Kontrolle des Einflusses von Endogenität und einer Reihe von anderen Faktoren, scheint optionale Preisbindung die Setzung von überdurchschnittlichen Fokalpreisen nicht insbesondere zu begünstigen." (Autorenreferat) "In media markets, products are highly differentiated but prices are often bunched at apparent focal points. I use a comprehensive cross-section data set on the German book market to assess whether such focal points are a result of upstream coordination and whether the option to impose resale price maintenance (RPM) played a facilitating role. Therewith, I provide empirical evidence to a long-lasting policy debate. Results suggest that focal prices are used to coordinate competition rather than collusion. Focal prices are mostly lower than expected from hedonic projections. In cases where the decisions on focal pricing and RPM are positively correlated, controlling for endogeneity and a number of other factors, RPM does not seem to facilitate above average focal pricing in particular."

The results of membrane and ozonation experiments carried out on various agro-industry effluents including fermentation (baker's yeast), corrugated board, opium alkaloid and textile dying industries are presented. The experiments were performed using lab-scale membrane and ozonation reactors. Color removals were in the range of 80 to 99% for the membrane treatment studies. Ozonation experiments have shown that color removals in the range of 83 to 98% are possible for the investigated wastewaters. Final color levels were lower than 100 Pt-Co unit, which is quite acceptable aesthetically. The relative unit treatment costs of ozonation were about two times higher than membrane systems especially for very strong colored effluents including fermentation and opium alkaloid industries. The study has demonstrated that both membrane and ozonation technologies are viable options for color removal.
