Relative influence of cultural identity and market access on agricultural biodiversity in swidden-fallow landscapes of eastern Panama
Creators: name: Kirby, Kathryn R.
Publisher: name: University of British Columbia
Year: 2012

description: Agricultural biodiversity is essential to local and global food security, yet is being rapidly eroded world-wide. The increasing reach of global transportation and trade networks is predicted to homogenize agriculture at regional scales. However, relatively little is known about how cultural values and norms, as reflected in local farmer decision-making, will interact with market forces to sustain or erode agricultural biodiversity. Working with farmers from three ethnic backgrounds — Black, Emberá or Kuna — in a region of Panama undergoing rapid landscape change, I determined the relative influence of farmer cultural identity and market access on several indicators of agrobiodiversity. Twelve villages were chosen to minimize environmental differences while maximizing differences in access. Villages were classified as “highway” or “remote” based on time and cost of travel to Panama City markets, with each ethnic group represented by two highway and two remote villages. From 2007-2009, a combination of crop inventories and land-use mapping (for 645 fields) as well as interviews with > 130 farmers were conducted. Diversity of staple food crop varieties, agroforest trees and shrubs, and the spatial and temporal dynamics of shifting cultivation were compared among villages. Farmer cultural identity had a stronger impact on agrobiodiversity indicators than did access. For staple food crops (e.g., maize, rice, yam, cassava, bananas, and taro), ethnicity explained 2.5 to 8.5 times more variation in assemblages than access. Distinct assemblages of staple crop landraces (varieties) and agroforest trees and shrubs were associated with different ethnic groups, even where access was high, reflecting culturally patterned dietary preferences, ceremonial or customary uses, and culturally-bounded seed-exchange networks. Mean number, size, and types of fields maintained (homegardens, outfield agroforests, annual fields, pastures), as well as their management (e.g., forest felling, herbicide use), also varied among ethnic groups. These differences reflected culturally-based crop preferences, values of land, traditional settlement patterns, and contemporary relationships to other actors, including the Panamanian government. Together, the distinct agricultural practices of individual ethnic groups combined to create diversity across many levels of biotic organization: from landrace, to species, to patch, to landscape. These findings strongly suggest that new approaches to conservation that support and respect heterogeneous socio-cultural systems will be critical to global efforts to maintain agrobiodiversity.

description: We present a detailed analysis of the X-ray emission of HS 1700+6416, a high redshift (z=2.7348), luminous quasar, classified as a Narrow Absorption Line (NAL) quasar on the basis of its SDSS spectrum. The source has been observed 9 times by Chandra and once by XMM from 2000 to 2007. Long term variability is clearly detected, between the observations, in the 2-10 keV flux varying by a factor of three (~3-9x10^-14 erg s^-1 cm^-2) and in the amount of neutral absorption (Nh < 10^22 cm^-2 in 2000 and 2002 and Nh=4.4+-1.2x10^22 cm^-2 in 2007). Most interestingly, one broad absorption feature is clearly detected at 10.3+-0.7 keV (rest frame) in the 2000 Chandra observation, while two similar features, at 8.9+-0.4 and at 12.5+-0.7 keV, are visible when the 8 contiguous Chandra observations of 2007 are stacked together. In the XMM observation of 2002, strongly affected by background flares, there is a hint for a similar feature at 8.0+-0.3 keV. We interpreted these features as absorption lines from a high velocity, highly ionized (i.e. Fe XXV, FeXXVI) outflowing gas. In this scenario, the outflow velocities inferred are in the range v=0.12-0.59c. To reproduce the observed features, the gas must have high column density (Nh>3x10^23 cm^-2), high ionization parameter (log(xi)>3.3 erg cm s^-1) and a large range of velocities (Delta V~10^4 km s^-1). This Absorption Line QSO is the fourth high-z quasar displaying X-ray signatures of variable, high velocity outflows, and among these, is the only one non-lensed. A rough estimate of the minimum kinetic energy carried by the wind of up to 18% L(bol), based on a biconical geometry of the wind, implies that the amount of energy injected in the outflow environment is large enough to produce effective mechanical feedback.

Application of Near-Surface Seismic Characterization to Sparsely Sampled Data Sets

Subjects: subject: Geophysics
subject: FOS: Earth and related environmental sciences

description: The unconsolidated, attenuative, relatively low velocity near surface layers of the Earth cause recording and imaging problems in seismic exploration surveys. Surface waves, recorded as ground roll, have propagated through these near surface layers, and therefore have been affected by these properties of interest. Multichannel analysis of surface waves, or MASW, uses these ground roll amplitudes and the dispersive character of surface waves to estimate near surface shear wave velocities. MASW techniques are applied in this study to synthetic and field data acquired at up to exploration survey scale, to estimate the near surface geometries and velocities. Two field datasets (from the Priddis thumper experiment and Hussar low frequency experiment) are interpolated and filtered to increase dispersion curve resolution. Least squares inversion is applied to the dispersion curve, and 1D near surface velocity profiles are estimated and combined to form 2D velocity profiles over the survey lines. The depth and shear wave velocity of near surface layers and bedrock is estimated to depths greater than 60 m.

description: We calculated the 4He trimer and tetramer ground and excited states with the LM2M2 potential using our Gaussian expansion method (GEM) for ab initio variational calculations of few-body systems. The method has extensively been used for a variety of three-, four- and five-body systems in nuclear physics and exotic atomic/molecular physics. The trimer (tetramer) wave function is expanded in terms of symmetric three-(four-)body Gaussian basis functions, ranging from very compact to very diffuse, without assuming any pair correlation function. Calculated results of the trimer ground and excited states are in excellent agreement with the literature. Binding energies of the tetramer ground and excited states are obtained to be 558.98 mK and 127.33 mK (0.93 mK below the trimer ground state), respectively. Precisely the same shape of the short-range correlation (r_ij < 4 Å) in the dimer appear in the ground and excited states of the trimer and tetramer. Analyzing the asymptotic wave functions (accurate up to 1000 Å) of those excited states, we propose a model which predicts the binding energy of the first excited state of 4He_N measured from the 4He_{N-1} ground state to be N/2(N-1)xB_2 using dimer binding energy B_2 only; fit in N=3 and 4 is excellent.

description: Saving a species from extinction is the minimum goal for conservationists. Ideally, we should conserve wild, flourishing, adaptive and self-sustaining populations. The IUCN recognises this ideal and states that only wild subpopulations can be considered for Red Listing. But what is wild? The absence of a measurable definition of wildness results in inconsistent Red Listing and thus inaccurate conservation progress reporting. As wildness exists along a spectrum from captive bred to completely free-roaming and many mammal species are subject to intensive breeding and production, which exist on a spectrum from purely commercial ranching to conservation orientated management, a framework that can unambiguously measure the conservation value or wildness of a subpopulation, regardless of the management system or philosophy is needed. Following two expert workshops, we designed a framework, comprising five variables relating to short-term subpopulation viability and four variables influencing long-term population resilience, to measure the species-specific wildness of subpopulations subject to varying management interventions. We used this framework to assess populations under various management systems and extrapolate adjusted Red List statuses for currently threatened species. The framework is a first attempt at providing a consistent and objective method to identify subpopulations that possess conservation value. As such, it will provide a foundation for policy-makers to provide different incentives to landowners focusing on biodiversity conservation versus commercial production. Importantly, developing an overall wildness status for our mammals, to complement their Red List status, will provide a holistic measure of conservation success rather than simply reporting risk of extinction.

description: The need for algorithms that optimize building energy consumption is usually motivated with the high energy consumption of buildings on a global scale. However, the current practice for evaluating the performance of such algorithms does not reflect this goal, as in most cases the performance is reported for one specific simulated building only, which provides no indication about the generalization of the score on other buildings. One approach to overcome this severe issue is to establish a shared collection of environments, each representing one simulated building setup, that would enable researchers to systematically compare and contrast the efficacy of their building optimization algorithms at scale. However, this requires that the individual environments are well designed for this goal. This paper is thus targeting the design of suitable environments for such a collection based on a detailed analysis of related publications that allows the identification of relevant characteristics for suitable environments. Based on this analysis a guide is developed that distills these characteristics into questions, intended to support a discussion of relevant topics during the design of such environments. Additional explanations and examples are provided for each question to make the guide more comprehensible. Finally, it is demonstrated how the guide can be applied, by utilizing it for the design of a novel environment, which represents an office building in tropical climate. This environment is released open source alongside this publication. We also indicate how test scenarios from existing publications could be enhanced to comply with the required characteristics according to our guide, underlining its importance for the future development and evaluation of building energy optimization algorithms, and thus for the sustainability of buildings in general.

description: The twenty-five short stories that comprise the creative component of Proximity Mines, Archives, while not linked in any strict formal sense, do share, in breadth of theme and comic temperament, a certain fixation on the psychological, social, and narratological difficulties attendant to the creation of realistic fiction. Employing a range of styles, from the subdued, minimalist strategies of Lydia Davis, Amy Hempel, and Raymond Carver, through the more exuberant, genre-dissolving prose of Donald Barthelme, David Foster Wallace, and Joshua Cohen, the collection performs and, in its sequencing, enacts a story of artistic maturation. Featuring a large cast of would-be writers and academics, the collection is at once deeply self-conscious and satirical. In composing a collection of disparate, fiendishly protean, short stories—from the stylistically sedate first-person narrative of “Terminal” through any number of long, one-sentence stories, pastiches, and nimbly ironic adaptations of canonical works (e.g., “Hills Like White Elephants, POV Hill”)—the collection both traces and challenges traditional forms of fictional representation. The accompanying critical afterword to this collection considers the relationship between creative writing and academic commentary, particularly as these roles fall to one author. Eschewing a standard, or purely theoretical approach, I undertake a vigorously subjective examination of the wide range of literary influences underpinning the stories in this collection. While examining the stylistic practices of a variety of writers (Mark Anthony Jarman, Stanley Elkin, Yann Martel), I make a case for my own aestheticism, aligning myself with those writers for whom the sentence serves as first philosophy. Finally, I argue that the inclusion of self-conscious or metafictive elements in a piece of fiction is not antithetical to literary realism.

description: It is observed that the interaction of an intense ultra-short laser pulse with an overdense gas jet results in the pulse collapse and the deposition of a significant part of energy in a small and well localized volume in the rising part of the gas jet, where the electrons are efficiently accelerated and heated. A collisionless plasma expansion over 150 microns at a sub-relativistic velocity (~c/3) has been optically monitored in time and space, and attributed to the quasistatic field ionization of the gas associated to the hot electron current. Numerical simulations in good agreement with the observations suggest the acceleration in the collapse region of relativistic electrons, along with the excitation of a sizeable magnetic dipole that sustains the electron current over several picoseconds. Perspectives of ion beam generation at high repetition rate directly from gas jets are discussed.
Mountain Torques and Northern Hemisphere Low-Frequency Variability. Part I: Hemispheric Aspects

description: The NCEP–NCAR reanalysis dataset for 1958–97 is used to analyze intraseasonal variations in mountain torques and the large-scale atmospheric circulation patterns associated with them. Spectral analysis of the atmospheric angular momentum (AAM) budget shows that the dominant variations of mountain torque have periodicities near 30 days and shorter, while the dominant AAM variations occur in the 40–60-day band. This difference is due to the 40–60-day AAM variations being primarily related to equatorial processes, while mountain torque variations are associated mostly with extratropical processes. The Northern Hemisphere (NH) mountain torque has enhanced power and significant spectral peaks in the 20–30-day band. The signal in this band accounts for 33% of the NH mountain torque variance, once the seasonal cycle has been removed. Lag composites of the NH 700-hPa geopotential heights based on the 20–30-day mountain torque signal show the latter to be associated with coherent large-scale patterns that resemble low-frequency oscillations identified in this band by previous authors. The composite patterns that are in phase quadrature with the 20–30-day NH mountain torque have a pronounced zonally symmetric component. These patterns are associated with substantial AAM variations, arguably driven by the NH mountain torque in this band. Principal component (PC) analysis of the NH 700-hPa heights shows that, in the 20–30-day band, the mountain torque is also in phase quadrature with the two leading PCs; the first corresponds to changes in the midlatitude jet intensity near the subtropics, while the second corresponds to the Arctic Oscillation. The relationships with AAM of the latter essentially occurs through the mass term. Mountain torques are, furthermore, nearly in phase with dominant patterns of low-frequency variability that exhibit substantial pressure gradients across the Rockies and the Tibetan Plateau.

description: Neglect and under-utilization of legumes such as soybeans and bambara groundnuts are the reason for increased food insufficiency in the Lake Victoria basin. Diversification of legumes into the cropping systems of Lake Victoria basin ensures protein rich diets and improved soil fertility. This study was carried out to evaluate agronomic characters of two soybean varieties and two bambara groundnut landraces cultivated on different soils of Lake Victoria basin. Seeds of two bambara groundnut landraces; Kakamega Cream (KAKC) and Busia Brown (BUSB) were collected from farmers in Kakamega and Busia counties, respectively in Kenya. Soil sampling was done at selected farmers’ fields with no history of inoculation in Kisumu, Port
 Victoria, Kendu bay and Karungu within Lake Victoria basin. Screen house experiment was performed in plastic pots with two plants of each cultivar. Randomized Complete Block Design was used. Agronomic characters of BUSB and KAKC landraces differed significant (p<0.05). Bambara groundnuts performed better in Port Victoria and Kendu bay soils than Kisumu and Karungu. Agronomic performance of two soybean varieties SB19 and ‘Safari’ on soils from four sites in Lake Victoria basin was significant (p<0.05). Soybeans yield in Port Victoria and Kendu bay soils was better compared to Kisumu and Karungu soils. Agronomic performance of bambara groundnuts and soybeans were influenced by soil type. Port Victoria and Kendu bay soils resulted in better growth compared to Kisumu and Karungu soils. Landrace KAKC and SB19 had better agronomic performers and are recommended to farmers and seed companies for certified seed production

description: Experiments under laboratory conditions were carried out to study the ordering in bidirectional pedestrian streams and its influence on the fundamental diagram (density-speed-flow relation). The Voronoi method is used to resolve the fine structure of the resulting velocity-density relations and spatial dependence of the measurements. The data show that the specific flow concept is applicable also for bidirectional streams. For various forms of ordering in bidirectional streams, no large differences among density-flow relationships are found in the observed density range. The fundamental diagrams of bidirectional streams with different forms of ordering are compared with that of unidirectional streams. The result shows differences in the shape of the relation for ρ > 1.0 m-2. The maximum of the specific flow in unidirectional streams is significantly larger than that in all bidirectional streams examined.

Welfare and Work Sanctions: Examining Discretion on the Front Lines

Publisher: name: Columbia University
Year: 2008
Subjects: Social service

description: Sanctions are a key tool for enforcing welfare reform's work requirements, but little attention has been paid to how laws, administrative procedures, judicial decisions, and worker discretion interact in the application of sanctions on the front lines. This study analyzes administrative fair hearing decisions and in‐depth interviews with sanctioned recipients. The findings suggest that workers interpret and apply sanction rules narrowly, failing to distinguish procedural violations from substantive ones. It also finds that workers are skeptical about claims of good cause exceptions from work rule violations, are strict in the application of the rules governing such exceptions, and overlook rules requiring them to show that a client's action (or inaction) was willful before imposing sanctions. Sanctions are applied across various groups of clients, including those engaged in ongoing work activities, as well as those who are disadvantaged and less willing to work.

Subjects: Public administration

description: An understudied area of public administration is administrative hearings, used by clients to challenge denials or reductions of aid in public welfare programs. They help ensure that officials are applying the law consistently, fairly and equitably, and as intended by policy makers. Drawing on 59 qualitative interviews with public assistance clients in an urban and suburban county in New York who received notices discontinuing or reducing their assistance, this study explores why clients appeal or not and their perceptions of hearings. The findings indicate that clients’ decisions to contest agency decisions were influenced by their perceptions of how workers treated them, their reactions to powerlessness and stigma, and their social networks, especially client networks. Clients who filed appeals perceived hearings as a valuable tool, albeit one that needed improvements. Although concerned with outcomes, they also focused on the procedural fairness of the hearing and whether they had an opportunity to fully present their case to an impartial decision maker. Although some clients had difficulty navigating the appeals process, procedural fairness was possible to achieve, despite the evident power and status disparities between the parties.

description: We analyze the ability of the three different Liquid Drop Mass (LDM) formulas to describe nuclear masses for nuclei in various deformation regions. Separating the 2149 measured nuclear species in eight sets with similar quadrupole deformations, we show that the masses of prolate deformed nuclei are better described than those of spherical ones. In fact, the prolate deformed nuclei are fitted with an RMS smaller than 750 keV, while for spherical and semi-magic species the RMS is always larger than 2000 keV. These results are found to be independent of pairing. The macroscopic sector of the Duflo-Zuker (DZ) mass model reproduces shell effects, while most of the deformation dependence is lost and the RMS is larger than in any LDM. Adding to the LDM the microscopically motivated DZ master terms introduces the shell effects, allowing for a significant reduction in the RMS of the fit but still exhibiting a better description of prolate deformed nuclei. The inclusion of shell effects following the Interacting Boson Model's ideas produces similar results.

description: We have reviewed the demographic characteristics of, and report abnormalities noted in, the de-novo growth and development of a paid oocyte donation programme. The personal profiles of all prospective oocyte donors were reviewed. Acceptance or rejection of candidates was based upon screening the results of medical, genetic and psychological testing. A total of 603 candidates initially responded to our advertisement. From this pool, 313 individuals were considered suitable and contacted by telephone. Following further conversation, 176 women were scheduled an entry interview. On completion of the formal screening process, 17.6% (n = 31) of those actually interviewed were denied entry. Thus, from the initial interested parties, only 23% of women wishing to participate in oocyte donation were considered suitable candidates. Given the high attrition rate, we concluded that the need for rigorous and thorough medical, psychological and genetic testing is mandatory for the establishment of a donor registry. Furthermore, professional counselling of prospective donors with respect to the results of tests and the implications of test results with respect to their future medical and reproductive health, are important parts of providing comprehensive care.

description: Although water is only present in trace amounts in the suboceanic upper mantle, it is thought to play a significant role in affecting mantle viscosity, melting and the generation of crust at mid-ocean ridges. The concentration of water in oceanic basalts has been observed to stay below 0.2wt%, except for water-rich basalts sampled near hotspots and generated by 'wet' mantle plumes. Here, however, we report unusually high water content in basaltic glasses from a cold region of the mid-ocean-ridge system in the equatorial Atlantic Ocean. These basalts are sodium-rich, having been generated by low degrees of melting of the mantle, and contain unusually high ratios of light versus heavy rare-earth elements, implying the presence of garnet in the melting region. We infer that water-rich basalts from such regions of thermal minima derive from low degrees of 'wet' melting greater than 60 km deep in the mantle, with minor dilution by melts produced by shallower 'dry' melting—a view supported by numerical modelling. We therefore conclude that oceanic basalts are water-rich not only near hotspots, but also at 'cold spots'.

description: Landowner resistance to Endangered Species Act (ESA) regulations is a key challenge to endangered species protection and recovery. Payments for Ecosystem Services (PES) strategies have been promoted as an effective market-based strategy for conserving imperiled species and offsetting ESA regulatory pressure on private landowners. The U.S. Fish and Wildlife Service (USFWS) recently proposed that a mix of PES and regulatory assurances be implemented in Florida to encourage cattlemen to engage in Florida panther recovery efforts. To identify cattlemen's preferences for the proposed programs we conducted a mail-based survey employing a choice experiment typically used in marketing research (i.e., best-worst scaling). We found that the utility associated with an incentive program depends on both the type and level of incentive offered and contract features that impact personal autonomy. Our findings suggest that voluntary conservation programs are most likely to enroll politically conservative landowners if these programs (1) provide per-acre payments or tax reductions, (2) are of shorter duration, (3) are based on norms of reciprocity, and (4) do not require overly intrusive or restrictive levels of monitoring to ensure program compliance.

description: Oil and gas pipeline accidents can lead to severe consequences such as explosions, injuries, and fatalities. In this thesis, onshore and offshore hazardous liquid and gas pipeline accidents that occurred between 2010 and 2017 are investigated. The main objective is to estimate failure rates and analyze how failure consequences are related to pipeline design. The results help the industry to minimize risks associated with pipelines and improve emergency response planning and accident management systems for new and existing pipelines. Linear and logistic regression and Bayesian rate estimation are applied for the data analyses. Onshore hazardous liquid gathering pipelines have the largest failure rate of 3.37E-03 accidents per km per year. The analysis results shows that ignition, injury, and fatality probabilities increase with diameter.
Energy dissipation in small-scale shape-change dynamics

description: Shape is an important feature of physical systems although very seldom it is addressed in the framework of a quantitative description approach. In this paper we propose to interpret the shape of things as a physical manifestation of the content of information associated with each thing and show that a change of shape in a physical system is necessarily connected with a change of its entropy and thus involves energy. We estimate the amount of energy dissipated during a shape change and propose experimental tests to be performed in nanoscale systems, to verify this prediction by measuring the expected dissipation in few simple cases.

Social service

description: The dramatic reshaping of welfare in 1996 included an arsenal of policy tools, from time limits, work requirements, and sanctions to work supports, job training and education, and case management services. To deploy these tools, welfare offices have been reconfigured and outside providers, including for profit and nonprofit agencies, enlisted. One policy tool, however, has been conspicuously and persistently absent: respect.
Studies of wax ester production and biochemical characterization of jojoba-type wax synthase in Arabidopsis thaliana
Creators: name: Liang, Wei-Wan Scott
Publisher: name: University of British Columbia
Year: 2011

description: Wax esters are components of surface lipids, serving as surface protectants for both terrestrial plants and animals. Wax esters are also specialized energy storage reserves for the organisms living in extreme environments, such as marine animals in Arctic and Antarctic oceans, the jojoba plant in the desert, and Acinetobacter species in the soil. Wax esters are also important substrates for industrial applications, such as the production of biodiesel, lubricants, cosmetics and polishes. Our current sources and production methods of wax esters from living organisms are not sufficient to meet market demands, so alternative sources including engineered oil crops that can generate sufficient amounts of wax esters are being sought. For my MSc project, I 1) investigated the feasibility of producing high levels of wax esters in the seed of Arabidopsis thaliana; 2) attempted to biochemically characterize new wax ester synthases that share amino acid similarity to the jojoba wax ester synthase; and 3) studied the promoter activity of the wax ester synthase encoded by the At5g55330 gene in Arabidopsis thaliana by a GUS assay. The first objective has been achieved, and the jojoba-type wax esters accumulated when the jojoba wax ester biosynthetic pathway was introduced in the seeds of Arabidopsis. I found that the enzyme encoded by the At5g55330 gene has wax ester synthase activity, but I was unable to characterize its substrate specificity. The third objective is still in progress, but my preliminary results to date indicate that the At5g55330 gene is transcribed in specific tissues of flowers, leaves, stem, and siliques.

description: In this paper, we analyze the nature and distribution of structured data on the Web. Web-scale information extraction, or the problem of creating structured tables using extraction from the entire web, is gathering lots of research interest. We perform a study to understand and quantify the value of Web-scale extraction, and how structured information is distributed amongst top aggregator websites and tail sites for various interesting domains. We believe this is the first study of its kind, and gives us new insights for information extraction over the Web.

description: Kurzbeschreibung (English below):

Nie gab es mehr kostenfrei zugängliche wissenschaftliche Materialien als heute. Noch vor zehn Jahren konnte man bei Literaturrecherchen auf viele Inhalte nicht sofort zugreifen, sondern etwa nur über Fernleihe der örtlichen Bibliothek.  Heute hat sich die Wissenschaft größtenteils dem Open-Science-Prinzip verschrieben: Dazu gehört, Publikationen und Lehrmaterialien als Teil der guten wissenschaftlichen Praxis frei zugänglich zu machen. Entsprechend kann man auch mobil über das Smartphone und z.B. über Google Scholar oder BASE auf viele Artikel sofort zugreifen.

Problematisch ist eher die Fülle an Informationen und auch die Auswahl. Was sind seriöse Quellen und was kennzeichnet eine legal nutzbare Open-Access-Publikation?

Der Vortrag an der Stadtbibliothek Erlangen im Rahmen der Reihe „Digitaler Salon“ (Montag, 05.02.2024, 17-18:00 Uhr) gibt einen Überblick und soll z.B. Oberstufenschüler*innen, Studierende aber auch Bürgerwissenschaftler*innen und interessierte Bürger*innen die Recherche und Nachnutzung entsprechender offener und qualitätsgesicherter wissenschaftlicher Materialien erleichtern.

In der Agenda beschäftigen wir uns mit der Frage „Was ist Open Access“, mit Suchmöglichkeiten nach Open-Access-Inhalten und rechtlichen Punkten der Nachnutzung. Die Folien sind auf Deutsch.

 

English description:

There has never been more scientific material available free of charge than today. Only ten years ago, many contents could not be accessed immediately during literature searches, but only via e.g. interlibrary loan from the local library.  Today, science has largely embraced the open science principle: This includes making publications and teaching materials "Open Access" freely accessible as part of good scientific practice. Accordingly, many articles can also be accessed immediately on a mobile basis via smartphone and, for example, via Google Scholar or BASE. 

What is more problematic is the abundance of information and the selection. What are reputable sources and what characterizes a legally usable open access publication?

The lecture at the Stadtbibliothek Erlangen as part of the series "Digital Salon" (Monday, 05.02.2024, 5-6:00 p.m.) provides an overview and is intended to facilitate, for example, pupils, high school students, but also citizen scientists and interested people to search and re-use appropriate open and quality-assured scientific materials. 

In the agenda we will deal with the question "What is Open Access?", with search possibilities for Open Access content and legal points of re-use. The slides are in German.

description: Cawston Game Ranch, located in Matabeleland Province in Zimbabwe, has operated as a trophy hunting destination since its inception in 1987. The ranch is situated in a semi-arid region with limited arable soils and subject to high rainfall variability. The ranch is surrounded by resettlement and subsistence farmers and their families. Vegetation is dominated by Colophospermum mopane – Acacia species on basalt soils. There are no perennial river systems requiring the maintenance of an extensive artificial game water supply system strategically located across the ranch. The 128 km2 property is surrounded by a 2.4 m high, 13 strand game fence. A mixture of grazers and mixed feeders make up the 17 species of ungulates with large predators limited to leopard and brown hyena. There are no buffalo, lion or elephant. Approximately 9,000 animals have been harvested over a 20-yearperiod. Rifle and bow trophy hunting and cropping are main source of revenue together with irregular live sales of impala, giraffe, sable, wildebeest, kudu and warthog. The founder populations have been monitored annually using robust road strip count surveys since 1997. These data have been analysed using the programme DISTANCE (Buckland, S.T., Anderson, D.R. Burnham, K.P. and Laake, J.L. 1993) to monitor changes in population estimates. A relationship using an abundance index for different species to estimate population numbers has been developed that provides game ranch managers with a simple tool to track population changes and hence establish sustainable quota offtakes without necessarily having to use complex and expensive survey techniques.
