The aim of this research is to investigate the effects of outdoor learning environments such as space camp on the perceptions of secondary school students about astronomy, career choices, and development of 21st century skills. Izmir space camp trip was organized in 2019. Qualitative study was conducted with secondary school 5th grade students attending the space camp (N = 24). Semi-structured interview form, focus group interview, space camp evaluation form and researcher observation notes were used as data collection tools. Data analysis was evaluated with content analysis and open coding. Students participated in the program of stars and planets adventure. In this program, the participants had the opportunity to use astronaut training simulators that give the feeling of living and working in space, to perform simulated shuttle missions, to learn new information from experts in the field and to get more detailed information about the professions. At the end of the study, it was revealed that out of school learning environments such as space camps had a positive effect on students. As a result of the study, it has been observed that the students perform their duties in a team collaboration in shuttle mission and develop their critical, questioning and thinking skills by experiencing the discussions about the subject with the experts. In addition, the misconception about Pluto was also determined.

With the advancement of modern era, architects have seen the architectural spaces as aesthetical masterpieces focusing more on their style, composition, pedigree, form, symbolism, allegory etc and how wonderful they look from the street then their design having an impact on its user and its value in terms of cognitive health, functionality and social determinant of mental and physical wellbeing. It is a well-known fact that our environment and surroundings play a vital role on our moods and health. More aesthetically improved, but not very smartly designed space affects our disposition and vigor. This situation leads to various health issues which can easily be curtailed with the proper use of architectural techniques employed. The Aim of the research paper is to identify the situation on hand around the city of Karachi and to focus upon the fact that people are socially, morally, ethically and physically at a state of ultimate distress and how the environment responsive architectural spaces can be wholesome for the human if they are more nearer to natural instincts then phoniness. The adopted methodology for this research was observational with qualitative comparisons of stakeholders with conversational interviews from the context of Pakistan specifically Karachi. Information for this was gathered through concentrated primary and secondary research methods both qualitative and quantitative.

The existence of Kampung Jajan Pasar in Gajahmungkur Administrative Village, as the village (kampong) in Semarang City that produces traditional snacks for its commodity, has made its people utilize their living houses as a production room to produce food for home industry. Having limited area and facing the demand to extend the rooms for their home industry, these villagers, mostly females, eventually add another use for rooms of their living houses (mix use). These living houses have become the socio-economic places which describe gender equality (for females) in business related to the utilization of rooms using mix use pattern. This research tries to describe the potency of the villagers and their village that has been appointed as the thematic village with topic scope of adaptation resilience at living house towards the production room function. This result is used as the base for the development model of living houses with the gender-based mix use pattern at Kampung Jajan Pasar in Gajahmungkur, Semarang. The data collecting method were literature studies, observations, interviews, and primary and secondary data extraction. The development of the model used graphic design model and the layout design. The given output is a graphic design model of living houses development based on gender and the layout of environmental space as the center of traditional snacks in Semarang City.

Health benefits have been linked to spending time outdoors in nature and green space. However, there is some evidence of inequities to accessing safe outdoor space, particularly in low-resource communities. The primary aim of this study is to assess attitudes towards nature and use of green space in urban areas. A secondary aim is to describe perceptions of physician-initiated nature prescriptions that target local pediatric populations. We conducted six focus group interviews with 42 residents who were guardians or caretakers of children living in low-resource neighborhoods in Philadelphia, PA. We analyzed interview data using a conventional content analysis approach. Three major themes emerged: (1) perceived benefits of being in nature (physical and mental health benefits), (2) barriers to time spent in nature (unsafe and undesirable conditions of local parks), and (3) desired features of outdoor green spaces (amenities that would increase park use). Additionally, we describe participants’ reactions to the idea of a pediatrician-delivered prescription for outdoor green space exposure for a child in their care. Adherence to nature prescriptions programs may hinge on local green space resources, as well as experiential and perceptual barriers and facilitators to nature and park accessibility among caregivers tasked with fulfilling a nature prescription for a child in their care.

ObjectivesTo develop a German version of the original University of Alabama at Birmingham Study of Aging Life-Space Assessment (LSA-D) for measurement of community mobility in older adults within the past 4 weeks and to evaluate its construct validity for urban and rural populations of older adults.DesignCross-sectional validation study.SettingTwo study centres in urban and rural German outpatient hospital settings.ParticipantsIn total, N=83 community-dwelling older adults were recruited (n=40 from urban and n=43 from rural areas; mean age was 78.5 years (SD=5.4); 49.4% men).Primary and secondary outcome measuresThe final version of the translated LSA-D was related to limitations in activities and instrumental activities of daily living (ADL/iADL) as primary outcome measure (primary hypothesis); and with sociodemographic factors, functional mobility, self-rated health, balance confidence and history of falls as secondary outcome measures to obtain construct validity. Further descriptive measurements of health included hand grip strength, screening of cognitive function, comorbidities and use of transportation. To assess construct validity, correlations between LSA-D and the primary and secondary outcome measures were examined for the total sample, and urban and rural subsamples using bivariate regression and multiple adjusted regression models. Descriptive analyses of LSA-D included different scoring methods for each region. All parameters were estimated using non-parametric bootstrapping procedure.ResultsIn the multiple adjusted model for the total sample, number of ADL/iADL limitations (β=−0.26; 95% CI=−0.42 to −0.08), Timed Up and Go Test (β=−0.37; 95% CI=−0.68 to −0.14), shared living arrangements (β=0.22; 95% CI=0.01 to 0.44) and history of falls in the past 6 months (β=−0.22; 95% CI=−0.41 to −0.05) showed significant associations with the LSA-D composite score, while living in urban area (β=−0.19; 95% CI=−0.42 to 0.03) and male gender (β=0.15; 95% CI=−0.04 to 0.35) were not significant.ConclusionThe LSA-D is a valid tool for measuring life-space mobility in German community-dwelling older adults within the past 4 weeks in ambulant urban and rural settings.Trial registration numberDRKS00019023.

Abstract Health benefits of blue spaces have been less studied compared with other urban natural environments. As a type of blue space, beaches are also affected by this lack of evidence, despite their cultural and economic importance in lots of coastal regions all over the world. Based on secondary health data from 3192 participants of the Health Survey of Barcelona 2016, we conducted a logit regression analysis to explore the relationship between people’s general health and beach proximity from their dwelling place, controlling for several health determinants. Our main results suggested that having good general health was less likely for a 1-km increase in the linear distance to the closest beach from people’s dwelling places (OR: 0.93; 95% CI: 0.87, 1.00). Moreover, the probability of having good general health was 45% higher for people living in the first 2 km from the beach (OR: 1.45; 95% CI: 1.01, 2.09), relative to those living >5–10 km from it. Also, these health effects were stronger for people with a low family income. These findings contribute to grow the currently small body of research related to health benefits of beach spaces. Likewise, they encourage fostering the use of these spaces for health promotion in cities, as well as protecting them and improving their accessibility and safety. Further research should lean towards the underlying causes of these health benefits linked to people’s exposure to beach spaces.

This paper explores a new artificial political ecology through a novel digital methodology. The emotional impacts of the replacement of living turfgrass landscapes with synthetic simulacra are researched via a netnography of animated and polarised online discussion. We investigate how the cultural use of domestic lawns has extended into the creation of non-living artificial lawns and how the environmental values of these new landscapes are debated. Synthetic polymer (plastic) grasses are increasingly being used as alternatives to turfgrass in domestic gardens, changing urban ecologies. We examine the emotional landscapes that are reproduced in online discourse. Paul Robbins showed that a certain suite of behaviours constitutes ‘Lawn People’. Here we demonstrate that ‘Artificial Lawn People’ act in reference to cultural expectations of a ‘good’ lawn to produce non-living, homogeneous, green and tidy gardens, yet their actions spark fierce criticism from others who do not value this new synthetic nature. Our research involved analysis of 948 online discussion posts, and introduces a secondary notion of ‘artificial people’ as our subjects were anonymous contributors to virtual public debates on the environment: generating impassioned polyvocal contestation. Mumsnet.com is a space of heated discussion between proponents and opponents of artificial lawns. We identify three topics: (i) emotional responses: artificial grass is polarising, and its social value contested; (ii) bio-physical affects: plastic fibres impact human and non-human life and (iii) environmental values: turfgrass replacement influences local and global political ecologies. The conclusions shed light on the dynamic relationships between the emotional values of living and non-living landscapes.

Understanding the evolution of the free-living, cyanobacterial, diazotrophTrichodesmiumis of great importance because of its critical role in oceanic biogeochemistry and primary production. Unlike the other >150 available genomes of free-living cyanobacteria, only 63.8% of theTrichodesmium erythraeum(strain IMS101) genome is predicted to encode protein, which is 20–25% less than the average for other cyanobacteria and nonpathogenic, free-living bacteria. We use distinctive isolates and metagenomic data to show that low coding density observed in IMS101 is a common feature of theTrichodesmiumgenus, both in culture and in situ. Transcriptome analysis indicates that 86% of the noncoding space is expressed, although the function of these transcripts is unclear. The density of noncoding, possible regulatory elements predicted inTrichodesmium, when normalized per intergenic kilobase, was comparable and twofold higher than that found in the gene-dense genomes of the sympatric cyanobacterial generaSynechococcusandProchlorococcus, respectively. ConservedTrichodesmiumnoncoding RNA secondary structures were predicted between most culture and metagenomic sequences, lending support to the structural conservation. Conservation of these intergenic regions in spatiotemporally separatedTrichodesmiumpopulations suggests possible genus-wide selection for their maintenance. These large intergenic spacers may have developed during intervals of strong genetic drift caused by periodic blooms of a subset of genotypes, which may have reduced effective population size. Our data suggest that transposition of selfish DNA, low effective population size, and high-fidelity replication allowed the unusual “inflation” of noncoding sequence observed inTrichodesmiumdespite its oligotrophic lifestyle.

OBJECTIVE: To evaluate the use of intrathecal baclofen for the treatment of muscle spasticity in patients with spinal cord injury. DATA SOURCES: A MEDLINE search was used to identify relevant and pertinent literature. Information was obtained from open-label clinical trials, abstracts, conference proceedings, and review articles. Index terms in the search included baclofen, spasticity, intrathecal drug infusion, spinal cord disease, and neurosurgery. DATA EXTRACTION: Studies were selected for review if they evaluated intrathecal baclofen in patients with spinal cord injury. Emphasis was placed on human studies published in the English language. Trials were reviewed by dosage regimen, therapeutic response, adverse effects, and complications. DATA SYNTHESIS: Thus far, intrathecal baclofen administration shows promise in the treatment of spasticity resulting from spinal cord trauma. Few complications and adverse effects have been reported. CONCLUSIONS: Muscle spasms and spasticity constitute a significant problem in spinal cord injuries, interfering with rehabilitation and leading to inconveniences and complications in these patients. Oral baclofen is the drug of choice for spasticity due to spinal cord trauma. It often is ineffective, however, because of the large dosages required to cross the blood-brain barrier and the subsequent appearance of central nervous system adverse effects. These adverse effects are not tolerated by many patients. Intrathecally administered baclofen has been approved by the Food and Drug Administration (FDA) for the treatment of spasticity in patients with spinal cord injury who are refractory to or cannot tolerate oral baclofen. It is intended for use only in implantable pumps approved by the FDA for the administration of baclofen into the intrathecal space. Intrathecal administration achieves high concentrations in the spinal cord with small dosages, thus reducing the incidence of central nervous system adverse effects. To date, approximately 350 patients with spinal cord injury have been treated with intrathecal baclofen. Reductions in spasticity have been demonstrated in both open-label and placebo-controlled trials. Patients also often make substantial gains in activities of daily living. Few adverse effects and complications have been reported. However, tolerance to the clinical effects of intrathecal baclofen has been reported. Further studies are needed to determine specific patient populations that may benefit most from intrathecal baclofen administration. Individual dosage ranges and follow-up care also need to be defined more completely. In addition, the question of whether tolerance detracts from long-term clinical benefits with intrathecal baclofen needs to be addressed.

Abstract. Local release of antibiotic has advantages in the treatment of chronic osteomyelitis and infected fractures. The adequacy of surgical debridement is still key to successful clearance of infection but local antibiotic carriers seem to afford greater success rates by targeting the residual organisms present after debridement and delivering much higher local antibiotic concentrations compared with systemic antibiotics alone. Biodegradable ceramic carriers can be used to fill osseous defects, which reduces the dead space and provides the potential for subsequent repair of the osseous defect as they dissolve away. A dissolving ceramic antibiotic carrier also raises the possibility of single stage surgery with definitive closure and avoids the need for subsequent surgery for spacer removal.In this article we provide an overview of the properties of various biodegradable ceramics, including calcium sulphate, the calcium orthophosphate ceramics, calcium phosphate cement and polyphasic carriers. We summarise the antibiotic elution properties as investigated in previous animal studies as well as the clinical outcomes from clinical research investigating their use in the surgical management of chronic osteomyelitis.Calcium sulphate pellets have been shown to be effective in treating local infection, although newer polyphasic carriers may support greater osseous repair and reduce the risk of further fracture or the need for secondary reconstructive surgery. The use of ceramic biocomposites to deliver antibiotics together with BMPs, bisphosphonates, growth factors or living cells is under investigation and merits further study.We propose a treatment protocol, based on the Cierny-Mader classification, to help guide the appropriate selection of a suitable ceramic antibiotic carrier in the surgical treatment of chronic osteomyelitis.

Denna studies syfte är att undersöka hur biareans storlek och användningssätt påverkar prisbildningen för småhusfastigheter. Genom att studera biareans prispåverkan kan studien ge indikationer gällande hanteringen av biareans värdepåverkan inom fastighetstaxeringen och om den bör genomgå en förändring. Eftersom taxeringsvärdet används vid en mängd olika situationer i samhället är det viktigt att det baseras på aktuella och tillförlitliga uppgifter. Studien utförs på uppdrag av Lantmäteriets sektion för fastighetsekonomi i Gävle. Fastighetstaxeringen i Sverige fastställs genom en form av massvärdering vilket utmynnar i taxeringsvärden för fastigheterna. Taxeringsvärdet är uppbyggt av olika värdefaktorer där storlek är en av dessa och uttrycks som värdearea i taxeringsvärdet. Denna värdearea består av boarean tillsammans med 20 % men max 20 m² av biarean. Biarea är sådan area som inte räknas som boarea, exempelvis källarutrymme, garage som nås inifrån eller inglasad altan. För att undersöka biareans prispåverkan för småhusfastigheter har hela Gävle kommun studerats genom en ortsprisanalys innehållande 559 köp. Mindre områden i Gävle har ingått i en enkätundersökning för att ta reda på fastighetsägarnas resonemang kring biareans värde. Endast småhusfastigheter med typkod 220 har ingått i studien och biarea i form av källarutrymme är den typ av biarea som studien inriktat sig främst på. Ortsprismaterialet har analyserats utefter nyckeltalen K/T-tal och pris per kvadratmeter.  Studiens resultat visar att det finns en positiv prispåverkan för småhus med biarea efter analys av hela ortsprismaterialet. Efter indelning i hög- och lågvärdeområden observeras denna positiva prispåverkan även inom högvärdeområden men inte inom lågvärdeområden. Ortsprismaterialet delades efter den initiala analysen in i storleksgrupper avseende boarea och andelsgrupper avseende biareans omfattning. För småhusfastigheter med boarea mellan 61-90 m² kan det utefter studiens resultat konstateras att betalningsviljan ökar ju större andel biarea småhuset har och att det är vid förekomsten av källarutrymme som störst positiv prispåverkan observeras. Samma observation kan göras när det gäller högvärdeområden. Ortsprisanalysens resultat styrks av enkätundersökningen där majoriteten av fastighetsägarna svarade att källarutrymmet var en bidragande faktor vid köpet och att fastighetsägarna värderar denna biarea högre än dess andel av taxeringsvärdet.

Ten Cape porcupines were radiotracked for one year in a savanna ecosystem at Nylsvley Nature Reserve, Transvaal, South Africa. Social organisation was characterised by family groups comprising a monogamous adult pair and immature offspring. Pair members usually shared the same burrow and utilised similar home range areas. Group size is probably determined by the time of offspring dispersal which is dependent upon population density and resource dispersion and abundance. Total home ranges (100% locations) of neighbouring pairs often showed considerable overlap, although areas of intensive use (90% locations) were largely exclusive and are thought to be defended as territories. Temporal space use patterns suggest that neighbours rarely encounter one another, indicating territorial maintenance through scent marking. Natural foragers had larger home ranges in winter than in summer, whereas range size of crop foragers was aseasonal, suggesting that range size in natural environments is determined by seasonal food availability.

Understanding and reducing domestic energy usage is seen as key to achieving national greenhouse gas emission targets, as well ensuring sustainable consumption at a domestic level. Domestic buildings represent a well-defined unit of space with numerous, easily measurable characteristics. They can also be perceived as being the terminal, end-use elements of a global resource distribution network, as defined by Jarvis et al., (2015). Such networks have drawn comparisons to biological organisms in how they acquire, transform, use and dispose of resources from their surrounding environment through a metabolic system of processing. This thesis aims to more deeply understand interrelations between, people, energy and space at a domestic level, assessing the influence of building geometry and social practices on scaling relationships relating to domestic energy consumption. Scaling relationships relating to the physical building properties have been studied extensively, however none directly assess how total energy usage scales across the domestic building stock. Data is abstracted form the 2012 English Housing Survey (EHS) housing stock dataset, which contains physical and demographic data relating to ~14k randomly sampled households across England. Scaling relationships are established between household size and total energy usage, both across the entire housing stock and by selected building characteristics, revealing scaling effects pertaining to specific domestic properties. Across the entire housing stock, a scaling exponent of 0.8032 ± 0.013 is observed for the relationship between household total floor area and total energy consumption, indicating a decrease in energy use per unit space with increased household size. This result is set within a context of building geometric properties and theories of societal metabolism, drawing extensively on current literature and this researches own findings. Understanding the origins of such scaling could potentially hold important implications for how individuals perceive their energy consumption, both in relation to physical domestic buildings and wider society.

A living room is defined in terms of place theory (Canter, 1977a): a relationship between actions, conceptions, and physical attributes of the setting. A new term "anti-living room" is created to highlight the importance of a subject's decision in the use of the living room. A "multiple use" of the living room, which is an antithesis of place theory, is tested against the empirical data collected between two different cultures. The paradigms of Tao are introduced to highlight the cultural differences in the pattern of use of living rooms. The English living room is hypothesised to be predominantly yang (B) (rational), whereas the Japanese living room being predominantly yin (B) (intuitive). Attempts are made to relate the I Ching to facet theory, both dealing with the complexity of "real life" issues. In order to understand the "entire phenomenon" of a living room, and to accommodate the "multidimensional nature" of experiences in a living room, facet theory and its associated multidimensional scaling procedures (SSA-1, MSA-1 and POSA) have been applied in this study. A facet theory postulates a priori definitions (mapping sentences) of the pattern of use of living rooms. MDS procedures try to reveal the underlying structures of the data. Thus it is possible to compare findings within similar living rooms and between different living rooms of different cultures when a facet approach is taken. A cross-cultural study is presented of patterns of behaviour, furniture possessed and attitudes towards living rooms in 115 homes in Guildford (England) and a comparable social sample of 145 households in Oyama (Japan), reveals that the Japanese engage in a wider range of activities in the Japanese living room (yin action - synthesis). In the English living room the English are likely to specialize its use, namely, relaxing and entertaining (yang action - analysis). In the field of man's relationship with his living room, the type of approach which might be termed intuitive speculation seems to be lost in a world devoted to the supposedly more scientific approach of objective analysis. As Alan Watts (1970) has speculated, this emphasis on the so-called objective may indeed be a handicap for Western man, for it enables him to retain his belief in the separateness of the ego from all that surrounds it. Although certain objective facts have been presented in this thesis, it is hoped by the author that its overall message is clear: allow yourself to be open to the consideration of relationships other than those that can be proved or disproved by scientific method, for it may well be in these that a deeper truth lies. Chapter 1 defines a living room in English and Japanese houses and briefly outlines the structure and aims of the thesis. Chapter 2 introduces the concept of space in the East and the West and discusses the living room in a cross-cultural context. Chapter 3 reviews the existing research on living rooms. Chapter 4 describes the research instruments and the selection of samples and introduces facet theory and its associated multivariate statistics. Chapter 5 analyses the structure of the pattern of living room activities. Chapter 6 analyses the structure of the use of living room furniture. Chapter 7 analyses the structure of satisfaction with living rooms. Chapter 8 develops a typology of families and relates it to living room activities. Chapter 9 develops a typology of physical properties of living rooms and relates it to living room activities. Chapter 10 discusses the implications of the research.

This thesis is an exercise in ideas of two realms, theoretical and practical, and an effort to mix the two to create architecture. The theoretical thesis is exemplified in the pairings of photos seen on the bottom of each page, taken from Second View: The Rephotographic Survey Project. As the reader examines the pairs of photos changes over time can be seen in each. Typically the greatest changes are manifestations of man's existence. I have treated this as a point of departure for the technical thesis of Permanence and Temporality. Man's temporal existence creates permanent reminders in the permanent structure of the earth. This thesis explores the nature of permanence and temporality in materials and uses them to express the classic dichotomy of service and served. As a practical thesis the project focuses on providing better urban living through natural light, natural ventilation, and the provisions for community and interaction with nature. A modification of Le Corbusier's Unite d'Habitation was explored by narrowing the building to bring natural light further into the unit while widening the unit to get natural light and ventilation even to the service spaces.

Alongside the destruction of habitat, the impact of invasive alien species (IAS) is considered as one of the most important threats to global biodiversity. Therefore, international directives as well as national legislation call for measures to prevent the further spread of already established IAS as well as to limit their negative effects on native flora and fauna. This study deals with one of these non-native species – the American mink (Neovison vison). In order to get information about ecology and behaviour of this semiaquatic carnivore, a small population in a north German fishpond area, where mink has been spreading since the 1970s, was investigated. During the years 2003 to 2006 data about annual and circadian activity patterns, space use, territorial system as well as feeding habits and their variations during different seasons were collected. For this purpose, altogether 14 individuals (nine males, five females) were monitored using radio-telemetry. Based on the results, the potential impact of American mink on indigenous species was discussed and implications for mink control and management were deduced. American mink are difficult to radio tag. The small difference between their head and neck circumferences mean that the radio collars must be worn tightly to prevent loss. A methodological evaluation of conventional collar transmitters revealed that in six out of eight cases serious skin injuries on the necks were the consequences. Therefore, all radio collars were removed and radio transmitters were surgically implanted in the peritoneal cavity of mink by veterinarians. One male bit open the sutures and died after emergency surgery, but in 13 cases implantation did not affect survival or reproduction of the mink. With reference to animal welfare, intraperitoneal implantation of radio transmitters (in combination with observation and quarantine for several days after operation) instead of external radio collars were recommended for long term telemetry studies of American mink. Analyses of annual activity patterns revealed significant differences in seasonal activity rates. Both sexes reduced their average activity rates in cold winter months (October to February) to about 23 %. This energy-saving strategy is possible because of sufficient food availability, especially of fish, at this time. In March, male as well as female mink considerably increased their activity to almost 40 % due to the mating season. In summer months, during the pup-raising period (May to August), female activity continued to be high (between 40 and 50 %). However, male mink which are not involved in rearing the young, were less active (about 30 %) until July. But in August and September, the time of juvenile dispersal followed by changes in the territorial system and intraspecific aggression, activity rates of males increased again up to 43 %. Circadian activity rhythms differed markedly between sexes. All investigated females exhibited a perennial diurnal pattern. Three of five investigated male mink showed typical nocturnal activity throughout the year. Two males displayed arrhythmic behaviour; they did not prefer any time of the day for activity. On the one hand, gender differences in annual as well as circadian activity patterns of American mink reflect the diversity in ecological constraints, primarily the investment into reproduction. On the other hand, the different temporal strategies of sexes may have the potential to reduce intraspecific, especially intersexual competition. Investigating territorial systems and space use of mink, in comparison to other European studies, relatively large home ranges combined with a quite low population density were observed. In summer months male mink used on average 15.4 km length of waterway and female mink used on average 9.3 km length of waterway. In accordance with the trend of activity rates, male and female mink reduced their large summer home ranges by more than half during the cold winter period. But all-season male mink used significantly larger areas than female mink. High intersexual overlapping rates of home ranges and low levels of intrasexual overlapping of neighbouring home ranges confirm intrasexual territoriality of American mink. Probably, the low population density (0.6-0.7 individuals/km2) allows such high variations in seasonal and sexual home range size. During the mating season males considerably enlarged their home ranges and roamed nearly through the entire study area in search of receptive females. The shifting of stable temporary home ranges observed within one season or between the same seasons of consecutive years demonstrates the highly dynamic nature of spatial behaviour among American mink. The recorded characteristic features of spatial and temporal behaviour should be considered when planning monitoring- and management measures of this invasive carnivore. For instance, the reduced home ranges and activity rates during winter months should be taken into account in mink trapping projects. Analyses of more than 2500 scatsamples of radio tracked mink show that investigated animals principally prey on fish, small mammals and birds (eggs inclusive). There were significant seasonal variations of diet composition. In spring, the three categories of prey - fish, mammals and birds (eggs inclusive) - were hunted in similar amounts. During summer, birds and their eggs made up the main part of the diet followed by mammals. In autumn, the proportion of birds in the mink diet decreased, whereas fish gained in importance. This trend continued during the winter period, when mink preyed almost exclusively on fish. Throughout the entire year amphibians, crustaceans, insects, molluscs and reptiles were found only occasionally in scatsamples. Among birds, the mink preyed mainly on the Eurasian Coot (Fulica atra) followed by the Mallard (Anas platyrhynchos). Mammalian prey was clearly dominated by the water vole (Arvicola terrestris) and among fish, mink hunted especially perch (Perca fluviatilis), roach (Rutilus rutilus) and carp (Cyprinus carpio). Results clearly demonstrate that mink is an opportunistic predator, which hunts its prey according to availability and vulnerability, respectively. Despite the high portions of fish in the autumn and winter diet, the economic damage to fishery caused by mink seems to be low. Perch and roach were preyed on in higher frequencies than the carp which is economically relevant. However, high predation on birds and their eggs during the breeding season indicates a potential negative impact of mink on waterfowl. To summarise, it can be noted that characteristic features of the anthropogenically influenced study area affect feeding habits, activity patterns, space use and density of local mink population. In this regard the management of fishponds, which influences seasonal availability of habitat- and food resources for mink, plays an important role. American mink is regarded as “invasive”, because a negative impact on native species has been proved by several European studies. Consequently, this study recommends management with a focus on effective monitoring and, if necessary, control or exclusion measures adapted to the specific local requirements. Furthermore, to prevent additional introductions into the wild, the still existing farms have to be protected against outbreaks and liberations. In the long term, a general ban on the trade and keeping of American mink would be desirable
Der Einfluss invasiver, gebietsfremder Arten wird neben der Habitatzerstörung als eine der größten Gefährdungen der Biodiversität weltweit angesehen. Sowohl internationale Umweltvereinbarungen als auch die nationale Gesetzgebung fordern daher Maßnahmen, die eine weitere Ausbreitung bereits etablierter invasiver Neozoen verhindern und deren negative Einflüsse minimieren. Die vorliegende Studie befasst sich mit einer dieser Neozoen - dem Amerikanischen Nerz bzw. Mink (Neovison vison). Um Erkenntnisse zu Ökologie und Verhalten des semiaquatischen Musteliden in Deutschland zu gewinnen, wurden Daten zu tages- und jahreszeitlichen Aktivitätsmustern, zu Raumnutzung und Territorialsystem sowie zur Nahrungswahl und den jahreszeitlichen Unterschieden im Beutespektrum der Art erhoben. Dafür konnten in den Jahren 2003 bis 2006 in einem Fischteich-Gebiet in Mecklenburg-Vorpommern, wo sich Minke bereits seit den 1970er Jahren etabliert haben, insgesamt 14 Individuen (neun Männchen, fünf Weibchen) radiotelemetrisch überwacht werden. Anhand der Ergebnisse wird einerseits der potentielle Einfluss des gebietsfremden Raubsäugers auf einheimische Arten abgeschätzt und diskutiert. Andererseits werden die Ergebnisse herangezogen, um effektive Monitoring- und Managementmaßnahmen abzuleiten. Eine methodische Evaluation von Halsbandsendern zeigte, dass in sechs von acht Fällen die getesteten Halsbänder, die aufgrund des sehr ähnlichen Hals-Kopf-Umfanges der Individuen relativ eng angelegt werden müssen, Hautverletzungen verursachten. Infolgedessen wurden die Halsbandsender gegen durch Tierärzte operativ in die Bauchhöhle eingesetzte Implantationssender ausgetauscht. Auch bei allen nachfolgend gefangenen Tieren wurden die Sender implantiert. Bei insgesamt 14 durchgeführten Erstimplantationen beeinflussten mit Ausnahme eines Falles (Tod durch Aufbeißen der Naht) die Implantate weder das Überleben, noch die Reproduktion der Minke. Daher ist v.a. in Hinblick auf Tierschutzaspekte die Senderimplantation (in Kombination mit einer Mehrtages-Quarantäne) anstatt der Verwendung von externen Halsbandsendern zu empfehlen. Die Analyse der circannuellen Aktivitätsmuster ergab signifikante Unterschiede der saisonalen Aktivitätsraten. Während der kalten Wintermonate (Oktober bis Februar) zeigten beide Geschlechter mit durchschnittlich etwa 23 % eine vergleichsweise geringe Aktivität. Diese energiesparende Verhaltensweise war möglich, da auch im Winter ein ausreichend hohes Nahrungsangebot, vor allem an Fisch, vorhanden war. Im März kam es sowohl bei den Männchen als auch bei den Weibchen zu einem durch die Paarungszeit verursachten, beträchtlichen Anstieg der mittleren Aktivitätsraten auf fast 40 %. In den Sommermonaten (Mai bis August) waren die weiblichen Tiere, durch die Anforderungen der Jungenaufzucht bedingt, anhaltend häufig aktiv (zwischen 40 und 50 %). Die Aktivitätsraten der nicht an der Jungenaufzucht beteiligten Männchen dagegen nahmen im April wieder ab, um bis zum Juli auf einem vergleichsweise geringen Niveau von etwa 30 % zu bleiben. Sie stiegen jedoch während der Monate August und September erneut auf etwa 43 % an. Zu dieser Zeit wandern gewöhnlich die Jungtiere ab und suchen sich ein eigenes Streifgebiet (= Aktionsraum), dadurch kommt es zu Änderungen im Territorialsystem und damit einhergehenden innerartlichen Auseinandersetzungen. Beide Geschlechter unterscheiden sich stark in ihren tageszeitlichen Aktivitätsrhythmen. Alle Weibchen waren ganzjährig tagaktiv. Von den fünf untersuchten Männchen zeigten drei typische Nachtaktivität im gesamten Jahresverlauf. Die beiden anderen männlichen Tiere verhielten sich in ihren Aktivitätsrhythmen indifferent, sie zeigten das ganze Jahr über keine Präferenzen für eine bestimmte Tageszeit. Die geschlechtsspezifischen Unterschiede sowohl in den circannuellen als auch in den circadianen Aktivitätsmustern spiegeln zum einen die verschiedenen Anforderungen an die Geschlechter wieder, vor allem die Investitionen in die Fortpflanzung. Zum anderen können die geschlechtsspezifisch unterschiedlichen Zeitnutzungs-Strategien zu einer Minimierung der innerartlichen, vorzugsweise der intersexuellen Konkurrenz führen. Die Analyse der Telemetriedaten hinsichtlich Raumnutzung und Territorialsystem ergab im Vergleich zu anderen europäischen Studien relativ große individuelle Aktionsräume verbunden mit einer geringen Populationsdichte im Untersuchungsgebiet. So erstreckten sich die durchschnittlich genutzten Sommerstreifgebiete der Männchen auf 15,4 km und die der Weibchen auf 9,3 km Flusslauf bzw. Teichufer. Entsprechend dem Trend der saisonalen Aktivitätsmuster, reduzierten beide Geschlechter ihre großen Sommerstreifgebiete während der Winterhalbjahre um mehr als die Hälfte der Fläche. Allerdings nutzten die Männchen zu allen Jahreszeiten wesentlich größere Aktionsräume als die weiblichen Minke. Große Streifgebietsüberlappungen zwischen den Geschlechtern sowie verhältnismäßig niedrige Überlappungsraten der benachbarten Streifgebiete von Tieren des gleichen Geschlechts bestätigen die intrasexuelle Territorialität der Art. Die erheblichen Unterschiede der saisonalen und geschlechtsspezifischen Aktionsraumgrößen werden vermutlich durch die ermittelte, vergleichsweise geringe Populationsdichte (0,6-0,7 Individuen/km2) ermöglicht. Die ausgedehnte und sich fast über das gesamte Untersuchungsgebiet erstreckende Raumnutzung der Männchen während der Paarungszeit ist durch die Suche nach fortpflanzungsbereiten Weibchen bedingt. Die Raumnutzung der untersuchten Minke unterliegt einer hohen Dynamik, dies wird durch die häufige räumliche Verschiebung temporär stabiler Streifgebiete innerhalb einer Jahreszeit oder auch zwischen den gleichen Jahreszeiten aufeinanderfolgender Jahre verdeutlicht. All diese ermittelten charakteristischen Besonderheiten im Raum-Zeit-Verhalten der Art sollten bei der Entwicklung von Monitoring- und Managementkonzepten berücksichtigt werden. So müssen beispielsweise bei der Fallenjagd im Winter die zu dieser Zeit stark verkleinerten Streifgebiete und die reduzierten Aktivitätsraten Beachtung finden. Die Analyse der über 2500 Losungsproben telemetrierter Minke zeigte, dass sich die untersuchten Tiere hauptsächlich von Fisch, Kleinsäugern und Vögeln (inklusive deren Eiern) ernährten. Dabei traten allerdings signifikante saisonale Unterschiede in der Nahrungs-zusammensetzung auf. So wurden im Frühjahr die drei Beutekategorien Fisch, Kleinsäuger sowie Vögel und deren Eier in ähnlichen Anteilen erbeutet. Während des Sommers bildeten Vögel und Vogeleier die Hauptbeute, gefolgt von Kleinsäugern. Im Herbst verringerte sich der Vogel- und Kleinsäugeranteil im Beutespektrum zugunsten von Fisch. Dieser Trend setzte sich bis in den Winter fort; in dieser Jahreszeit ernährten sich die Minke fast ausschließlich von Fisch. Amphibien, Reptilien, Krebstiere, Insekten und Mollusken wurden im gesamten Jahresverlauf nur gelegentlich gefressen. Innerhalb der Gruppe der Vögel prädierten die Minke vor allem Blässhühner (Fulica atra), gefolgt von Stockenten (Anas platyrhynchos). Das Kleinsäuger-Beutespektrum wurde eindeutig von der Schermaus (Arvicola terrestris) dominiert und unter den Fischen erbeuteten die Minke vorzugsweise Flussbarsche (Perca fluviatilis), Plötzen (Rutilus rutilus) und Karpfen (Cyprinus carpio). Die Ergebnisse der Nahrungsanalyse bestätigen den Mink als einen opportunistischen Prädator, der seine Beutetiere je nach Verfügbarkeit bzw. dem erforderlichen Jagdaufwand nutzt. Trotz des hohen Fischanteils in der Herbst- und Winternahrung ist der durch den Mink verursachte ökonomische Schaden schätzungsweise relativ gering. Flussbarsch und Plötze wurden in höheren Frequenzanteilen erbeutet als der wirtschaftlich relevante Karpfen. Die starke Prädation von Wasservögeln und deren Eiern besonders in den Frühjahrs- und Sommermonaten weist allerdings auf einen potentiell negativen Einfluss des invasiven Raubsäugers auf diese Tiergruppe hin. Zusammenfassend lässt sich festhalten, dass die spezifischen Charakteristika des anthropogen geprägten Untersuchungsgebietes sowohl Nahrungsökologie und Aktivitätsmuster als auch Raumnutzung und Populationsdichte der lokalen Minkpopulation beeinflussen. Eine besondere Rolle hierbei spielt die Bewirtschaftung der Fischteiche, denn vor allem daraus resultiert für die Minke eine saisonal unterschiedliche Verfügbarkeit an Lebensraum und Nahrung. Negative Auswirkungen des Amerikanischen Nerzes auf die einheimische Tierwelt wurden in anderen europäischen Ländern belegt und rechtfertigen die Einstufung dieser Art als „invasiv“. Demzufolge wird in der vorliegenden Arbeit ein Management empfohlen, bei dem der Focus auf einem effektiven Monitoring und gegebenenfalls auf zweckmäßigen, an die lokalen Bedingungen angepassten Fang- oder Abwehrmaßnahmen liegt. Zudem sollten, um einer weiteren Ausbringung in das Freiland vorzubeugen, die wenigen noch existierenden Minkfarmen besser gegen Ausbrüche bzw. Freilassungsaktionen gesichert werden. Langfristig ist ein generelles Besitz- und Vermarktungsverbot für die Art wünschenswert

ENGLISH ABSTRACT: This study was aimed at using secondary data to conduct an investigation into the relationship between macro-economic factors on one hand and aspects of household life on the other hand. On the basis of the results thereof, an assessment was to be made of how such a relationship reflected on the living arrangements of households in contemporary South African society. The basis of the analysis was secondary data from the October Household Survey (OHS-96) data set, which is rich in specific information encompassing various aspects of human life, like demographic details and household variables as well as health, education and employment variables. As expected, the results showed that the current state of living arrangements of households is characterised by positive relationships between income levels on the one hand and households variables like type of dwelling and dwelling ownership on the other hand. However, the same findings further revealed a surprising outcome that unlike expected, there is no clear relationship between income and another significant household variable i.e. household size (members). However, our findings lead us to a conclusion that on the whole, there is a hypothesised relationship between macro-economic conditions of a country on one hand, and patterns in living arrangements of households on the other hand. The results further revealed that as expected, the factors of magisterial district and race/population groups have an effect on this relationship that reflect our legacy of social and economic development policies of the apartheid era which gave rise to urban (metropolitan) and racial bias in the socio-economic development of households. The results thereof are that African households in particular, and urban poor black households in general, have become the least prosperous in terms of material or economic living conditions. The implications of these findings for theory and policy are highlighted. At the level of methodology, the valuable experience of this study served to further highlight the worth of secondary data analysis, not only in general economic terms, but also as invaluable educational or teaching tool for students which recommends its increased use by all practitioners or institutions of social research methods.
AFRIKAANSE OPSOMMING: Die Internet en sy Kuberruimtes is ontwikkel in die 1960s as 'n manier om inligting oor te dra sonder die risiko van intersepsie en vernietiging. Vandag, 40 jaar later het die Internet gegroei in beide grootte en toepassing. Die mees algemene gebruike is nogsteeds kommunikasie en die oordrag van informasie. Hierdie tesis is 'n etnografiese studie van my ervaringe in 'n Kuberruimte van die Internet- 'n virtuele gemeenskap byname Amazon City.com. Virtuele gemeenskappe is areas op die Internet waar mense bymekaar kom om hul daaglikse lewens, kwessies en enige iets toepaslik vir die spesifieke gemeenskap, te bespreek. Die tipe gemeenskap word gesien as 'n reaksie van die verval van "derde plekke" in af-lyn lewe en globalisering Die gemeenskap wat vorm in hierdie areas ontwikkel kulturele veronderstelling. Hierdie veronderstellings word openbaar aan 'n nuwe lid deur tyd en interaksie in die konferensie area. Die veronderstellings wat ek ervaar het strek van kennis benodig om 'n aanvaarde en suksesvolle lid van die gemeenskap te word, tot taal gebruik en identiteit van die lede. Die konklusie is bereik dat lede hul interaksie en lidmaatskap in hierdie gemenskappe as net so bevredigend en "eg" ervaar as hul aktiwiteite in hul af-lyn lewe. Verdere aspekte wat 'n webblad 'n suksesvolle en ekonomiese vatbare besigheids strategie maak vir sy eienaar, was my volgende fokus. Internet besigheid groei teen 'n geweldige spoed, en impliseer nie slegs die verkoop van produkte aanlyn nie. Rekenaar-ondersteunde kommunikasie toestelle is geimplimenteer op kommersiële webbladsye nadat dit gevind is in die vroeë 1990s dat mense soek vir 'n plek wat meer is as net nog 'n winkel. Ander maniere wat hierde dot com webbladsye gebruik om inkomste te genereer en of die lede gesien word as burgers of as verbruikers word ook bestudeer. Daar is gevind dat die lede hulself sien as burgers maar webbladsy lojaliteit sal die lede aanspoor om as verbruikers op te tree indien nodig. Die kommersiële aspekte van die tipe webbladsy is 'n noodsaaklik deel vir die voortbestaan van die dot com webbladsy, en die gemeenskap wat daar ontwikkel.

“Adapting Snäckan 8” aims to investigate material and immaterial value while transforming an existing built structure. Current development plans seek to demolish and replace the existing building by a new, 10 meter wider, 4.5 meter taller building of office spaces; increasing the scale of the Klara quarter once more, just as during the Norrmalm Regulation historically. Excluding both: plans for housing, as well as the so called “Culture House”. A space that included a café, a library and a cinema, for everyone, including especially the homeless people of Stockholm.Accompanied by a notion that when we demolish built structures, not only do we demolish material, but also social structures that have been built up over time; the ecological aspects of adaptive re-use are expanded by social urgency. In light of the housing crisis and increasing social segregation as well as the development of the pandemic, the accessibility of a home is now perhaps more pressing than ever. This project therefore aims to provide affordable, inclusive mixed-use living within the city centre, adapting Snäckan 8 to changing rhythms and patterns of daily life. Thereby hoping to continue writing the story of Snäckan 8, rather than erasing it.

The monograph discusses current problems and features of the use and operation of airspace, its air navigation support for effective air traffic management and improving the safety of state and commercial aviation.

Prepared for publication on the basis of research conducted by scientific and pedagogical specialists of the Institute of radio engineering, electronics and communications of the Saint Petersburg state University of aerospace instrumentation. It is intended for radio engineering specialists, and can also be used by teachers, students and cadets of educational organizations of higher and secondary professional education in the field of civil aviation.

The history of the genus Homo, and of the sapiens species in particular, is different from that of other species due to the extreme importance of cultural evolution compared to biological evolution. But from the discovery of how to use fire and generate it, up to the invention of the steam engine, man essentially lives, like the other organisms of the biosphere, on the energy flow guaranteed by solar radiation. With the encounter between machines and fossil fuels and the entry into the era of engines, the rules of the game change radically, and the activities of Homo sapiens change in extent and intensity, in such a way as to progressively reduce the living space of all other animal and plant species, except for the allied and commensal ones. The global industrialized society arising from the meeting between machines and fossil sources is presently facing two fundamental difficulties: the gradual saturation of terrestrial ecosystems with the waste of social and economic metabolism, and the finiteness of fossil energy sources, which are not easy replacement due to their special chemical-physical properties.

AbstractNeuralgia can be defined as paroxysmal, intense intermittent pain that is usually confined to specific nerve branches to the head and neck. The trigeminal nerve is responsible for sensory innervation of the scalp, face and mouth, and damage or disease to this nerve may result in sensory loss, pain or both. >85% of cases of Trigeminal Neuralgia are of the classic type known as Classical Trigeminal Neuralgia (CTN), while the remaining cases can be separated to secondary Trigeminal Neuralgia (STN). STN is thought to be initiated by multiple sclerosis or a space-occupying lesion affecting the trigeminal nerve, whereas the leading cause of CTN is known to be compression of the trigeminal nerve in the region of the dorsal root entry zone by a blood vessel. There is no guaranteed cure for the condition of Trigeminal Neuralgia, but there are several treatment options that can give relief. In this chapter, we review the common neuralgias occurring within the oral and maxillofacial region with special emphasis on Trigeminal Neuralgia. We will discuss the historical evolution of treatment including the medical and surgical modalities with the use of current literature and newer developments. It has been highlighted that the first line of treatment for trigeminal neuralgia is still pharmacological treatment, with Carbamazepine and Oxcarbazepine being the first choice. Possible surgical methods of treatment are discussed within this chapter including modalities such as Microvascular Decompression, Gamma Knife Radiosurgery and Peripheral Neurectomy. As an OMF surgeon, it is important to obtain a good clinical history to rule out other pathology including dental focus. Many clinicians involved ranging from primary care dentists and doctors to secondary care (neurologists, Oral Medicine, OMFS, etc.) to deliver the appropriate first course of action, which is the medical management. The management of TN patients should be carried out in a multidisciplinary setting to allow the patients to choose the best-suited option for them. It is also important to set up self-help groups to enable them to share knowledge and information for themselves and their family members for the best possible outcomes.

This study uses secondary data to discuss views of indigenous scholars on the importance of using African indigenous philosophies as underpinnings for indigenous research in order to reclaim the dignity of African indigenous knowledge. For many years, African indigenous knowledge has been marginalized and constructed using Western worldviews and methods. African indigenous philosophies were deemed non-existent and non-fitting to be in the academic space by many non-indigenous scholars who believed that indigenous research methods cannot be developed because there are no specific generalized frameworks. In correcting and reclaiming the knowledge and dignity of African indigenous knowledge, this study argues for the decolonization and indigenization of research by utilizing African indigenous philosophies which focuses on African philosophical beliefs and values, that constitute their own way of living, doing, and being. Such research will prevent indigenous people's knowledge from being misrepresented, divided, mystified, commodified, condensed, and misinterpreted.

The street grid of New Orleans is uniquely configured relative to its unusual geography and 19^th century settlement patterns. The method for creating an ordered street system adjacent to the dramatic undulations of the Mississippi River is as intricate and variable as the landscape itself. A combination of factors from the land-use patterns of plantations to the conflicting geometries of orderly grids and irregular curves conspired to produce the intelligible though complex urban landscape of New Orleans and a unique urban morphology. The order of streets and avenues in New Orleans produces nearly as many urban anomalies as it does regular ones and the building stock of the city often struggles to adapt to the irregularities of the “system.” These unique urban conditions were formed over the course of a century, yielding useful slivers of accidental public space and secret, interstitial worlds of compact living.

In the fifth century B.C., Herodotus reported that there had been a time when a person could walk across North Africa from the Atlantic to the Indian Ocean and be always in the shade of trees. No more: the land was well on the way to becoming the desert we know today. Herodotus generalized: "Man stalks across the landscape, and deserts follow in his footsteps." In the tenth century A.D., a Samanid prince identified four earthly paradises: the regions of Samarkand, southern Persia, southern Iraq, and Damascus. No one who has visited any of these sites now would dream of calling it a paradise. They have been cursed with wars, but warfare is only a secondary cause of their degradation. Throughout history human exploitation of the earth has produced this progression: colonize—destroy—move on. When the Pollyannas write history they focus only on the first of these three actions, the desirable effects of which were most evident during the rapid colonization of the New World. In 1845 a now obscure American journalist coined a deathless phrase when he spoke of "the fulfillment of our manifest destiny to overspread the continent allotted by Providence." "Manifest destiny" is one of those catchphrases we love. We would not welcome the words of a journalist who identified colonization as but a prelude to destruction and abandonment. The restless "moving on" of the human species has depended on always having fresh land to move to. Optimists are not easily frightened by the results, of course: as late as 1980 one Pollyanna brightly explained how all turned out for the best in this best of all possible worlds: "Each year deserts the world over engulf an area the size of Massachusetts. A great deal of land lost is agricultural. . . . Fortunately, however, land is always being replaced or coming under cultivation to make up for land lost." An ecologist—ever guided by the question "And then what?"—would insist on a clarification of the above quotation: Does "always" mean "forever"? If so, it implies that there are no limits to earthly space. It is not surprising that ecologists are not the most popular of people in a growth-oriented economy.

In article the question of a problem of processing of household waste which in our life became today especially sharp is brought up. Still absolutely new things become not necessary as quickly get out of fashion. Before consumers there is a task how to prolong life cycle of textile materials of high quality. The approach allowing to develop conditions of production of garments with a possibility of use differently of textured materials in one model design is represented.

Along with the global wave of urbanization, urban agglomerations with megacities as the core have become the main form of urbanization in various countries. The polarization effect around the metropolis leads to the centripetal flow of capital, labour, land and other resource elements in the surrounding small towns, which causes the shrinkage of small towns in the metropolis, such as population reduction, economic recession, idle housing and dilapidated space. The shrinkage of small towns in the metropolis has become a global issue. However, as an important spatial unit in the spectrum of urbanization that serves, connects and couples urban and rural areas, the shrinking phenomenon faced by small towns has an important influence on the healthy development of urbanization. Exploring the development path of adaptive shrinkage for small towns has become an important part of the healthy urbanization of metropolises. Based on the public data of population, land and economy in Wuhan, China from 2004 to 2014, this paper uses GIS and other spatial analysis technologies to comprehensively measure the relevant characteristics of the shrinkage of small towns. The results showed that the small towns in Wuhan are in the form of "unbalanced shrinkage" under a local growth. And the towns present a spatial pattern of "circle increasing shrinkage" around the boundary of main downtown. With a further exploration of the formation mechanism of "unbalanced shrinkage", it is found that this shrinkage pattern is caused by a combination function of various factors, such as downtown deprivation in the policies supply, centripetal delivery of social capital and reconstruction of regional division of labour network. Based on this, this paper tries to propose some response paths for small towns in metropolitan areas to adapt to the "unbalanced shrinkage". First of all, the small towns should integrate into the regional differential development pattern and strive for the institutional dividend. Secondly, the small towns should promote an industrial transformation, and then attract the market release of social capital. Thirdly, the small towns should improve the living environment and promote intensive use of land. Through these paths, we can stabilize the three-level structure system of “urban-township-village”, and ensure the healthy urbanization of metropolitan areas.

[The final form of this paper was published in the journal Issues in Informing Science and Information Technology.] This paper presents the success story of the intuitive vision of an ICT high school educator in South Africa. The growth and evolution of a Community of Practice, towards a full-fledged living lab is investigated. A grounded theory study analyses the living lab concept and highlights some of the current challenges secondary high school ICT education face within the South African educational landscape. Some of the concepts, ideas, best practices and lessons learned in the establishment and running of two web based technologies to support secondary school ICT subjects is discussed. The researchers present a motivation for the use of living labs to address some of the issues identified and highlights how the existing platforms fits into bigger design.

This paper aims to identify associations between demographic and socioeconomic factors and home Internet use patterns in the Central Queensland region, Australia. It found that people living outside of Rockhampton, male, those with higher education levels, married, those with higher income level, or fully employed tend to use Internet more for work at home; people living in Rockhampton, those within the youngest group (18-24), or with secondary education level or higher tend to use Internet more for education; people living in Rockhampton, those within the youngest group, never married, or unemployed tend to use Internet more for entertainment; males, people within the youngest group, those with lower family income, or either semi-employed or unemployed tend to use Internet more for information search; females, people with no children, or lower family income tend to use Internet more for communication through email; married people tend to use Internet for financial management; and people within 25-39 year old group, with higher education levels tend to use Internet more for on-line purchases. It is suggested that further research should be conducted to monitor the youngest age group in home Internet use for entertainment and information search.

A secondary flow calculation method is presented, which makes use of the meridional vorticity transport equation. Circumferentially mean flow quantities are calculated using an inverse procedure. The method makes use of the mean kinetic energy integral equation and calculates simultaneously hub and tip secondary flow development. Emphasis is placed upon the use of a coherent two-zone model and particular care is taken in order to describe adequately the flow inside an unbounded (external), semi-bounded (annulus) and fully-bounded (bladed) space. Along with the velocity field, the losses, the defect forces and the corresponding additional work realized inside the viscous wall shear layer are calculated for stationary and rotating flow. An approximate model for the interaction of the viscous shear layers and the external flow is used, which takes into account the meridional and the peripheral blockage. When shock waves are present in the external flow, an approximate interaction model is used, additionally, which calculates the static pressure field resulting from the interaction of the shock wave and the corresponding wall shear layer. The method has been applied to two one stage transonic flow compressors and the results of the comparison between theory and experiment are presented and discussed.

Modern society is often referred to as a society of knowledge and information. In this context, activating methods are experiencing a renaissance. Such methods offer students the opportunity to progress to perceive more accurately and comprehensively, recognize and experience stimuli, develop their perception and thinking, effectively solve problems, communicate and act objectively and successfully. It can be an active teaching and learning that is the way that can contribute to such a goal in the era of systematic cognition and differentiation of information, raising living standards, changing lifestyles, and globalizing the world. The question is how to bridge this epoch in the sense of preparing students for their active roles as inhabitants of the planet, accepting a responsible way of life in line with sustainable development. It is especially important for environmental education to understand the context and learn interdisciplinary, comprehensively, to be able to distinguish values, to take interest in and get to know one's surroundings, to discover, to take the initiative and to be sensitive and receptive as well. Therefore, it is necessary to think about the didactic methods that teachers use in their lessons and focus on activating methods and forms of teaching, leading to the fulfilment of such sub-objectives. In this context, the aim of the paper is to introduce and analyse new activating didactic approaches to the implementation of the cross-curricular topic “Man and the environment” as designed by graduate students of the Institute of Education and Communication at the Czech University of Life Sciences Prague between the academic years 2019 and 2020. Didactic approaches (such as project-based learning, field learning with the support of worksheets, and the use of nature educational trails) applicable in practice were designed for selected localities, focusing on increasing the interest and awareness of secondary and secondary vocational school students about their surrounding natural environment.
