Conservation at what cost? : a case study of the social implications of protected areas and the role of local people in Vietnam
Creators: name: Timko, Joleen
Publisher: name: University of British Columbia
Year: 2009

description: Interest in the role that local people's knowledge and experiences can play in natural resource conservation is increasing throughout the world. This is due in part because protected areas and national parks have repeatedly proven to be unsuccessful in achieving conservation objectives, and in part because they threaten the existence of nearby rural communities. When severe restrictions are placed on access to the forest resources local people depend upon for survival, poverty is often exacerbated. The result is that local people feel contempt and distrust for the protected area. In order to mitigate the impacts that protected areas have had on rural populations, local people have become the locus for development activities which either strive to understand the value of local ecological knowledge and experiences, or which encourage local people to participate in often externally-designed initiatives. Only a community-based natural resource management (CBNRM) approach, which is grounded in an understanding of local people's realities and livelihood needs, can unite the strengths of local knowledge and participation. To gain insight into the opportunities and constraints facing planners seeking to take a participatory approach to park management, a case study was conducted of Cat Ba National Park, Vietnam. Semi-structured interviews were carried out in two communities within the park, Khe Sau Hamlet and Viet Hai Village. The results show that local people in Cat Ba are willing and able to participate in the park's conservation activities, but that they are inhibited from doing so by political and socio-economic factors. As well, it was found that local people possess detailed ecological knowledge about the park's forest resources. This knowledge has been developed by keen observations of the surrounding environment for generations. Improving local livelihoods was identified by local people as essential to reducing their dependence on forest biodiversity. Drawing on ideas offered by Cat Ba interviewees and analysis of other findings from the case study, suggestions are offered for capturing opportunities and overcoming barriers to effective participatory park management.

description: In this paper, we present a learning-based approach to determining acceptance of arguments under several abstract argumentation semantics. More specifically, we propose an argumentation graph neural network (AGNN) that learns a message-passing algorithm to predict the likelihood of an argument being accepted. The experimental results demonstrate that the AGNN can almost perfectly predict the acceptability under different semantics and scales well for larger argumentation frameworks. Furthermore, analysing the behaviour of the message-passing algorithm shows that the AGNN learns to adhere to basic principles of argument semantics as identified in the literature, and can thus be trained to predict extensions under the different semantics - we show how the latter can be done for multi-extension semantics by using AGNNs to guide a basic search.

Subjects: Travel motivation, tourist satisfaction, perceived attractiveness, relaxation, destination image, responsiveness

description: This study investigates the relationship between travel motivation and tourist satisfaction at Port Harcourt Pleasure Park. It adopted a cross-sectional survey as a research design. The total population consists of one hundred (100) tourists surveyed using convenient sampling technique. Face validity was employed. Cronbach Alpha was used to ascertain the reliability of instrument. Kendall's Coefficient of Concordance (tau_b) was used to analyse the hypotheses while percentage was used to analyse tourists’ demographic characteristics with the aid of statistical package for social sciences (20.0). This study found that travel motivation has a positive significant relationship with tourist satisfaction in Port Harcourt Pleasure Park. This study concludes that travel motivation that is measured on perceived attractiveness and relaxation has the capacity of fulfilling tourist satisfactions in destinations.

description: In soft X-rays, the Monogem ring is an object with a diameter of 25° located in the Galactic anti-centre. It is believed to be a faint, evolved, local supernova remnant. The ring is also visible in the far-ultraviolet, and a few optical filaments are related. It is not seen at radio wavelengths, as other large supernova remnants are. We study a narrow about 4.5° long, faint H$α$-filament, G203.7+11.5,that is seen towards the centre of the Monogem ring. It causes depolarisation and excessive Faraday rotation of radio polarisation data. Polarisation observations at $λ$11\ cm and $λ$21\ cm with the Effelsberg 100-m telescope were analysed. in addition to $WMAP$ data, extragalactic rotation measures, and H$α$ data. A Faraday-screen model was applied. From the analysis of the depolarisation properties of the H$α$ filament, we derived a line-of-sight magnetic field, $B_{||}$, of 26$\pm5μ$G for a distance of 300~pc and an electron density, $n_\mathrm{e}$, of 1.6~cm$^{-3}$. The absolute largest rotation measure of G203.7+11.5 is -86$\pm3$~rad~ m$^{-2}$, where the magnetic field direction has the opposite sign from the large-scale Galactic field. We estimated the average synchrotron emissivity at $λ$21\ cm up to 300~pc distance towards G203.7+11.5 to about 1.1~K $T_\mathrm{b}$/kpc, which is higher than typical Milky Way values. The magnetic field within G203.7+11.5 is unexpected in direction and strength. Most likely, the filament is related to the Monogem-ring shock, where interactions with ambient clouds may cause local magnetic field reversals. We confirm earlier findings of an enhanced but direction-dependent local synchrotron emissivity.

description: Abundances of about 18 elements including the heavy elements Y and Zr are determined from Hubble Space Telescope Space Telescope Imaging Spectrograph ultraviolet spectra of seven extreme helium stars (EHes): LSE 78, BD+10 2179, V1920 Cyg, HD 124448, PV Tel, LS IV -1 2, and FQ Aqr. New optical spectra of the three stars -- BD+10 2179, V1920 Cyg, and HD 124448 were analysed. The abundance analyses is done using LTE line formation and LTE model atmospheres especially constructed for these EHe stars. The stellar parameters derived from an EHe's UV spectrum are in satisfactory agreement with those derived from its optical spectrum. Adopted abundances for the seven EHes are from a combination of the UV and optical analyses. Published results for an additional ten EHes provide abundances obtained in a nearly uniform manner for a total of 17 EHes, the largest sample on record. The initial metallicity of an EHe is indicated by the abundance of elements from Al to Ni; Fe is adopted to be the representative of initial metallicity. Iron abundances range from approximately solar to about one-hundredth of solar. Clues to EHe evolution are contained within the H, He, C, N, O, Y, and Zr abundances. Two novel results are (i) the O abundance for some stars is close to the predicted initial abundance yet the N abundance indicates almost complete conversion of initial C, N, and O to N by the CNO-cycles; (ii) three of the seven stars with UV spectra show a strong enhancement of Y and Zr attributable to an s-process. The observed compositions are discussed in light of expectations from accretion of a He white dwarf by a CO white dwarf.

description: We study the dynamics of iterates at the transition to chaos in the logistic map and find that it is constituted by an infinite family of Mori's $q$-phase transitions. Starting from Feigenbaum's $σ$ function for the diameters ratio, we determine the atypical weak sensitivity to initial conditions $ξ_{t}$ associated to each $q$-phase transition and find that it obeys the form suggested by the Tsallis statistics. The specific values of the variable $q$ at which the $q$-phase transitions take place are identified with the specific values for the Tsallis entropic index $q$ in the corresponding $ξ_{t}$. We describe too the bifurcation gap induced by external noise and show that its properties exhibit the characteristic elements of glassy dynamics close to vitrification in supercooled liquids, e.g. two-step relaxation, aging and a relationship between relaxation time and entropy.

description: We present a new method to measure colors and magnitudes of the tip of the red giant branch in multiple bandpasses simultaneously by fitting an n-dimensional Gaussian to photometry of candidate tip stars. We demonstrate that this method has several advantages over traditional edge detection, particularly in regimes where the TRGB magnitude is strongly color-dependent, as is the case in the near-infrared. We apply this method to a re-reduction of a set of optical and near-IR HST data originally presented in Dalcanton et al. (2012). The re-reduction takes advantage of the increased depth and accuracy in the NIR photometry enabled by simultaneous reduction with higher resolution optical data in crowded fields (Williams et al. 2014). We compare three possible absolute calibrations of the resulting apparent TRGB measurements, one adopting the same distance moduli as in Dalcanton et al. (2012), and two based on predicted TRGB absolute magnitudes from two widely-used, modern sets of model isochrones. We find systematic offsets among the model absolute calibrations at the ~0.1 mag level, in line with previous investigations. The models also have difficulty reproducing the optical-NIR color-magnitude behavior of our measurements, making these observations a useful benchmark for future improvements.

The situation and the evolution of forest management by Aboriginal people in British Columbia

Publisher: name: University of British Columbia

description: This thesis addresses the situation of First Nations people in forestry of British Columbia. Aboriginal people in British Columbia have been involved in the forest industry as laborers since the 1850s when the commercial logging operations began in the province, but have been politically and economically marginalized in the industry. The institutional and economic factors not only have restricted aboriginal people to control over forest resources on their traditional lands but have affected their forest management practices. For aboriginal communities, it is a critical issue that protecting old growth forests, with which they are culturally associated, without giving up economic benefit generated from harvesting these forests. In order to suggest possible changes and approaches for shaping native forest management in the existing institutional and economic frameworks, I examined the issues of provincial forestry and analyzed how these issues effect and interact with aboriginal people. It is important but difficult for First Nations to obtain forest tenure because their resource management is related to their land rights. However, the issues of aboriginal people in forestry overlap with those of the province. Thus, perspectives and participation of aboriginal people is critical for the government and the industry. Forestry of British Columbia is in transition and has begun to consider the potential contribution of aboriginal people to sustainable forestry. Therefore, aboriginal people have a significant role to play in the future of forestry.
On the non-occurrence of Type I X-ray bursts from the Black Hole Candidates
Creators: name: Mitra, Abhas
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: It has been justifiably questioned that if the Black Hole Candidates (BHCs) have a ``hard surface'' why Type I X-ray bursts are not seen from them (Nayayan, R., Black Holes in Astrophysics, New J. Phys., 7, 199-218, 2005). It is pointed out that a ``physical surface'' need not always be ``hard'' and in could be ``gaseous'' in case the compact object is sufficiently hot (Mitra, A., The day of reckoning: the value of the integration constant in the vacuum Schwarzschild solution, physics/0504076, p1-p6; BHs or Eternally Collapsing Objects: A review of 90 years of misconceptions, in Focus on Black Hole Research, Nova Sc. Pub., NY, p1-p94, 2006). Even if a ``hard surface'' would be there, presence of strong strong intrinsic magnetic field could inhibit Type I X-ray burst from a compact object as is the case for Her X-1. Thus, non-occurrence of Type I bursts actually rules out those alternatives of BHs which are either non-magnetized or cold and, hence, is no evidence for existence of Event Horizons (EHs). On the other hand, from the first principle, we again show that the BHCs being uncharged and having finite masses cannot be BHs, because uncharged BHs have a unique mass M=0. Thus the previous results that the so-called BHCs are actually extremely hot, ultramagnetized, Magnetospheric Eternally Collapsing Objects (MECOs) (Robertson, S. & Leiter, D., Astrophys. J. 565, 447-451, 2002; MECO Model of galactic BH Candidates and active galactic nuclei, in: New Developments in BLack Hole Research, NOva Sc. Pub., NY, p1-p44, 2006) rather than anything else get reconfirmed by non-occurrence of Type I X-ray bursts in BHCs.

description: Food assistance programs play an important role in meeting the basic needs of low income households. This paper examines the interaction among food stamps, labor force participation and food insecurity status of low-income households under different program design and economic conditions. A simultaneous equation model with three probit equations links the program, work force participation and outcome. Results based on the Survey of Program Dynamics data suggest that Food Stamp Program participation is more responsive to changes in the program benefits than to changes in unemployment rate or nonlabor income; food insecurity status is more responsive to changes in the food program benefit or unemployment rate, than to nonlabor income.

description: According to the standard protocol of spatial public goods game, a cooperator player invests not only into his own game but also into the games organized by neighboring partners. In this work, we relax this assumption by allowing cooperators to decide which neighboring group to prefer instead of supporting them uniformly. In particular, we assume that they select their most successful neighbor and focus external investments exclusively into the related group. We show that this very simple alteration of the dynamical rule results in a surprisingly positive evolutionary outcome -- cooperators prevail even in harsh environment represented by small values of the synergy factor in the game. The microscopic mechanism behind the reported success of the cooperator strategy can be explained by a blocking mechanism which affects the propagations of competing strategies in a biased way. Our results, which remain intact by using different interaction topologies, reveal that it could be beneficial to concentrate individual efforts to reach a higher global wellbeing.

description: The negative impact of climate change may be reduced with mitigation strategies in developing countries. Some studies project that developing countries in the Tropics will be worse off than developed countries under different scenarios of global climate change, due to warmer climates, increased droughts and floods. Their populations are poorer, and therefore more vulnerable to climate stresses and shocks. Bolivia is an example: A country that experienced climate variability, political change and structural adjustment throughout the nineties. These forces have an effect on rural livelihood strategies. Canonical correlations identify the elements of strategies that impact on both income and diversity of the household portfolio. The ability of rural people to access resources, accumulate assets, and engage in certain activities allow some to adapt to variability in the short run, providing insights into characteristics or traits of technologies, markets, and policies that may contribute to long term adaptation.

description: Clinicians in the frontline need to assess quickly whether a patient with symptoms indeed has COVID-19 or not. The difficulty of this task is exacerbated in low resource settings that may not have access to biotechnology tests. Furthermore, Tuberculosis (TB) remains a major health problem in several low- and middle-income countries and its common symptoms include fever, cough and tiredness, similarly to COVID-19. In order to help in the detection of COVID-19, we propose the extraction of deep features (DF) from chest X-ray images, a technology available in most hospitals, and their subsequent classification using machine learning methods that do not require large computational resources. We compiled a five-class dataset of X-ray chest images including a balanced number of COVID-19, viral pneumonia, bacterial pneumonia, TB, and healthy cases. We compared the performance of pipelines combining 14 individual state-of-the-art pre-trained deep networks for DF extraction with traditional machine learning classifiers. A pipeline consisting of ResNet-50 for DF computation and ensemble of subspace discriminant classifier was the best performer in the classification of the five classes, achieving a detection accuracy of 91.6+ 2.6% (accuracy + 95% Confidence Interval). Furthermore, the same pipeline achieved accuracies of 98.6+1.4% and 99.9+0.5% in simpler three-class and two-class classification problems focused on distinguishing COVID-19, TB and healthy cases; and COVID-19 and healthy images, respectively. The pipeline was computationally efficient requiring just 0.19 second to extract DF per X-ray image and 2 minutes for training a traditional classifier with more than 2000 images on a CPU machine. The results suggest the potential benefits of using our pipeline in the detection of COVID-19, particularly in resource-limited settings and it can run with limited computational resources.

description: Subgraphs and cycles are often used to characterize the local properties of complex networks. Here we show that the subgraph structure of real networks is highly time dependent: as the network grows, the density of some subgraphs remains unchanged, while the density of others increase at a rate that is determined by the network's degree distribution and clustering properties. This inhomogeneous evolution process, supported by direct measurements on several real networks, leads to systematic shifts in the overall subgraph spectrum and to an inevitable overrepresentation of some subgraphs and cycles.

description: We use statistical tools to characterize the response of an excitable system to periodic perturbations. The system is an optically injected semiconductor laser under pulsed perturbations of the phase of the injected field. We characterize the laser response by counting the number of pulses emitted by the laser, within a time interval, $Δ$T , that starts when a perturbation is applied. The success rate, SR($Δ$T), is then defined as the number of pulses emitted in the interval $Δ$T , relative to the number of perturbations. The analysis of the variation of SR with $Δ$T allows to separate a constant lag of technical origin and a frequency-dependent lag of physical and dynamical origin. Once the lag is accounted for, the success rate clearly captures locked and unlocked regimes and the transitions between them. We anticipate that the success rate will be a practical tool for analyzing the output of periodically forced systems, particularly when very regular oscillations need to be generated via small periodic perturbations.

description: This paper examines the effect of foreign intellectual property right (IPR) systems and the policies that comprise them on U.S. exports of biotechnology related agricultural input industries. Policy components include the extent of patent coverage across industry sectors, enforcement mechanisms, provisions for loss of patent protection, memberships to other international patent agreements, and duration of patent protection. Extending the empirical and theoretical work of Smith (2002), this paper uses a gravity model to analyze how IPRs affect the market power and market expansion effects of exports to countries with differing abilities to imitate technology. The findings suggest that strengthening global IPRs grant a market power effect to U.S. exporters; strong IPRs reduce U.S. exports by awarding a temporary monopoly over the protected good. However, the analysis of the individual policy components of an IPR system reveal which components inhibit trade through market power effects and which components counterbalance it through market expansion effects, increasing the flow of trade and access to biotechnology related agricultural inputs.

Our research examines the interaction between public investments, community health, and adoption of productivity and land enhancing technologies by households in the northern Ethiopian state of Tigray. Agricultural technology adoption decisions are modeled as a sequential process where the timing of choices can matter. We find that time spent sick and opportunity costs of caring for sick family members are significant factors in adoption. Sickness, through its impact on household income and labor allocation decisions for healthcare and other activities, significantly reduces the likelihood of technology adoption. Our findings suggest that agencies working to improve agricultural productivity and land resource conservation should consider not only the financial status of potential adopters, but also their related health situation.

description: The spread of infectious disease among and between wild domesticated animals has become a major problem worldwide. Upon analyzing the dynamics of wildlife growth and infection when the disease animals cannot be identified separately from healthy wildlife prior to the kill, we find that harvest-based strategies alone have no impact on disease transmission. Other controls that directly influence disease transmission and/or mortality are required. Next, we analyze the socially optimal management of infectious wildlife. The model is applied to the problem of bovine tuberculosis among Michigan white-tailed deer, with non-selective harvests and supplemental feeding being the control variables. Using a two-state linear control model, we find a two-dimensional singular path is optimal (as opposed to a more conventional bang-bang solution) as part of a cycle that results in the disease remaining endemic in the wildlife. This result follows from non-selective harvesting and intermittent wildlife productivity gains from supplemental feeding.
Spatially Resolved Spectral Analysis of Vela Shrapnel D

description: The ROSAT all-sky survey discovered several `shrapnels', showing boomerang structures outside the Vela supernova remnant. We observed shrapnel D with the XMM-Newton satellite. There is an X-ray bright ridge structure in our FOV running from north to south. Applying the VNEI model to X-ray spectra of various regions, we find that the plasma in the eastern part from the X-ray ridge is significantly different from that in the western part. The X-ray spectra in the western part can be represented by a single-temperature component. The abundances of heavy elements are almost uniform, whereas they are heavily overabundant, except for Fe; the relative abundances to the solar values are O about 5, Ne about 10, Mg about 10, Fe about 1. This indicates that shrapnel D originated from the ejecta of the supernova. We find that the plasma in the eastern part from the ridge consists of two components with different temperatures; the hot component comes from the ejecta, while the cold component comes from the interstellar matter. These two components are considered to be in contact with each other, forming a contact discontinuity. Around the northern part of the contact discontinuity, we find wave-like structures of which the typical scale are comparable with that of the Rayleigh--Taylor instability.

RI-VIS D5.4 Guidelines for effective communication in Africa

Year: 2021

description: This guideline document aims to provide European research infrastructure (EU RI) Communication Officers and other RI stakeholders with tools and recommendations to develop communication strategies to effectively engage with African stakeholders. It was designed to serve as a roadmap for developing context-appropriate communications with African stakeholders, in view of increasing RI visibility to target audiences and to make RIs more ‘findable’ on the web (and on their respective websites, with clear information regarding international collaboration or other opportunities). Developed as part of the Horizon 2020-funded RI-VIS project (https://ri-vis.eu), the document is based on a survey, which was filled out by 22 respondents from Belgium, Botswana, Kenya, South Africa, Tanzania, The Gambia, Uganda, and Zambia. The main takeaways from the survey include the desire for collaborative approaches, including, but not limited to, staff exchanges and training, and the need to consider limited funding opportunities when reaching out to potential targets. It does not seem realistic to consider African stakeholders as another (future) potential market for EU RI services, whereby services would be paid for at full market cost; alternative, more collaborative approaches, based on local context and needs, may thus be more appropriate. Some respondents indicated difficulty knowing how to reach out to EU RI stakeholders and ensure timely follow-up. This highlights the need for EU RIs to have appropriate outreach strategies in place, with pre-identified contact points and a process for responding to inquiries (in addition to seeking collaboration). Some of the findings are applicable to other regions: the need for cultural sensitivity, awareness of the local socio-economic/political context, attention to language (and the nuances certain terms may carry), the need for clear captivating messages, the importance of collaborative approaches (involving the non-EU participants as leaders in project design), etc. Ultimately, communication serves to support organisational objectives; here we can see that communication can also inform RIs’ international outreach strategies, providing a new lens to see and engage with the world.

description: The massive star-forming region W75N~(B) is thought to host a cluster of massive protostars (VLA~1, VLA~2, and VLA~3) undergoing different evolutionary stages. In this work, we present radio continuum data with the highest sensitivity and angular resolution obtained to date in this region, using the VLA-A and covering a wide range of frequencies (4-48~GHz), which allowed us to study the morphology and the nature of the emission of the different radio continuum sources. We also performed complementary studies with multi-epoch VLA data and ALMA archive data at 1.3 mm wavelength. We find that VLA~1 is driving a thermal radio jet at scales of $\approx$0.1 arcsec ($\approx$130 au), but also shows signs of an incipient hyper-compact HII region at scales of $\lesssim$ 1 arcsec ($\lesssim$ 1300~au). VLA~3 is also driving a thermal radio jet at scales of a few tenths of arcsec (few hundred of au). We conclude that this jet is shock-exciting the radio continuum sources Bc and VLA~4 (obscured HH objects), which show proper motions moving outward from VLA~3 at velocities of $\approx$112--118~km/s. We have also detected three new weak radio continuum sources, two of them associated with millimeter continuum cores observed with ALMA, suggesting that these two sources are also embedded YSOs in this massive star-forming region.

description: We study the observational constraints of CMB temperature and polarization anisotropies on models of dark energy, with special focus on models with variation in properties of dark energy with time. We demonstrate that the key constraint from CMB observations arises from the location of acoustic peaks. An additional constraint arises from the limits on Omega_nr from the relative amplitudes of acoustic peaks. Further, we show that the distance to the last scattering surface is not how the CMB observations constrain the combination of parameters for models of dark energy. We also use constraints from Supernova observations and show that unlike the Gold and Silver samples, the SNLS sample prefers a region of parameter space that has a significant overlap with the region preferred by the CMB observations. This is a verification of a conjecture made by us in an earlier work. We discuss combined constraints from WMAP5 and SNLS observations. We find that models with w ~ -1 are preferred for models with a constant equation of state parameters. In case of models with a time varying dark energy, we show that constraints on evolution of dark energy density are almost independent of the type of variation assumed for the equation of state parameter. This makes it easy to get approximate constraints from CMB observations on arbitrary models of dark energy. Constraints on models with a time varying dark energy are predominantly due to CMB observations, with Supernova constraints playing only a marginal role.
