description: This study examined the effect of students’ engagement in social vices on social studies students’ academic performance in University of Calabar. Three research questions were raised and three null hypotheses were stated and tested at .05 level of significant. The study adopted ex-post-facto research design. The sample for the study comprised 200 social studies students of university of Calabar randomly selected from year one through year four in the department comprising 789students. The instruments used for data collection were ”Students’ Engagement in Social Vices questionnaire (SESVQ)” and Essay- test questions based on the course outlines of each year taken from their semester examination, were used for data collection. The face and content validity of the instruments were determined by research experts and the reliability of instruments was also determined using Cronbach alpha reliability method with .78. Data collection was done by the researcher which were analysed using independent t-test analysis tested at .05 level of significance. The results of the Statistical analysis revealed that social vices such as deadly diseases, dangerous acts like engagement in illegal act such as cultism, act of smoking and taking of illegal substances, alcoholism, rape, robbery and others have significant effect on social studies students’ academic performance in University of Calabar. Based on the findings, it was recommended that the responsibility of preventing or curbing general student vices in University should be a collective effort of the parents, lecturers, religious leaders, authorities of the Universities as well as the government. This can be done through appropriate upbringing, counselling and necessary sanctions in process of the students’ formation.

description: We show that a discrete exchange symmetry can give rise to realistic dark matter candidates in models with warped extra dimensions. We show how to realize our construction in a variety of models with warped extra dimensions and study in detail a realistic model of Gauge-Higgs Unification/composite Higgs in which the observed amount of dark matter is naturally reproduced. In this model, a realistic pattern of electroweak symmetry breaking typically occurs in a region of parameter space in which the fit to the electroweak precision observables improves, the Higgs is heavier than the experimental bound and new light quark resonances are predicted. We also quantify the fine-tuning of such scenarios, and discuss in which sense Gauge-Higgs Unification models result in a natural theory of electroweak symmetry breaking.

Rape of the world: an ecofeminist critique of international environmental law
Creators: name: Rochette, Annie
Publisher: name: University of British Columbia
Year: 2009

description: Over the last twenty years, international environmental law has attempted to address the global threats to the health of our planet including ozone layer depletion, climate change, global deforestation, the pollution of freshwater resources and the oceans and species extinction. Unfortunately, the state of the environment is not improving as fast as environmental conventions come forth. The premise for this thesis is therefore that international environmental law is not effective in protecting the natural environment. Responsible for the survival of their families and communities, women in developing countries are the most vulnerable to environmental degradation as dwindling natural and freshwater resources and soil erosion threaten their survival base. Unfortunately, international environmental law does little to acknowledge this vulnerability and even less to assist women in developing countries cope with environmental degradation. The vast knowledge of ecosystems held by women in developing countries is also largely ignored, thus marginalizing their way of knowing and disregarding potential solutions to environmental problems. This thesis therefore takes a critical look from an ecofeminist standpoint at the traditional characteristics of international environmental law such as states' sovereign right to exploit their natural resources, states' right to development and the emphasis of international environmental law on science and technology. The thesis also examines emerging principles of international environmental law such as sustainable development, intergenerational equity, common concern of humankind, and the precautionary principle, which attempt to address some of the concerns raised by the more traditional approach. However, the thesis concludes that despite these new developments, international environmental law is still premised on an androcentric perspective of the natural environment which impedes it from achieving true environmental protection and which serves to continue the marginalization of women. In this thesis, I argue that a new conceptualization of the relationship between humankind and the natural environment is necessary in order to save our planet from ecological disaster and that ecofeminism can offer such an alternative view. Finally, the conclusion will suggest a few concrete ways of including women's perspectives and ways of knowing into the negotiation of environmental conventions and in their implementation.
Particle-hole symmetry and the dirty boson problem

description: We study the role of particle-hole symmetry on the universality class of various quantum phase transitions corresponding to the onset of superfluidity at zero temperature of bosons in a quenched random medium. The functional integral formulation of this problem in d spatial dimensions yields a (d+1)-dimensional classical XY-model with extended disorder--the so-called random rod problem. Particle-hole symmetry may then be broken by adding nonzero site energies. We may distinguish three cases: (i) exact particle-hole symmetry, in which the site energies all vanish, (ii) statistical particle-hole symmetry in which the site energy distribution is symmetric about zero, vanishing on average, and (iii) complete absence of particle-hole symmetry in which the distribution is generic. We explore in each case the nature of the excitations in the non-superfluid Mott insulating and Bose glass phases. We find that the Bose glass compressibility, which has the interpretation of a temporal spin stiffness or superfluid density, is positive in cases (ii) and (iii), but that it vanishes with an essential singularity as full particle-hole symmetry is restored. We then focus on the critical point and discuss the relevance of type (ii) particle-hole symmetry breaking perturbations to the random rod critical behavior. We argue that a perturbation of type (iii) is irrelevant to the resulting type (ii) critical behavior: the statistical symmetry is restored on large scales close to the critical point, and case (ii) therefore describes the dirty boson fixed point. To study higher dimensions we attempt, with partial success, to generalize the Dorogovtsev-Cardy-Boyanovsky double epsilon expansion technique to this problem. The qualitative renormalization group flow picture this technique provides is quite compelling.

description: We present a survey of rigourous quantization results obtained in recent works on quantum free fields in de Sitter space. For the "massive'' cases which are associated to principal series representations of the de Sitter group SO\_0(1,4), the construction is based on analyticity requirements on the Wightman two-point function. For the "massless'' cases (e.g. minimally coupled or conformal), associated to the discrete series, the quantization schemes are of the Gupta-Bleuler-Krein type.

description: Complex networks topologies present interesting and surprising properties, such as community structures, which can be exploited to optimize communication, to find new efficient and context-aware routing algorithms or simply to understand the dynamics and meaning of relationships among nodes. Complex networks are gaining more and more importance as a reference model and are a powerful interpretation tool for many different kinds of natural, biological and social networks, where directed relationships and contextual belonging of nodes to many different communities is a matter of fact. This paper starts from the definition of modularity function, given by M. Newman to evaluate the goodness of network community decompositions, and extends it to the more general case of directed graphs with overlapping community structures. Interesting properties of the proposed extension are discussed, a method for finding overlapping communities is proposed and results of its application to benchmark case-studies are reported. We also propose a new dataset which could be used as a reference benchmark for overlapping community structures identification.

description: In this paper, we present an experimental study of weakly non-linear interaction of axisymmetric internal gravity waves in a resonant cavity, supported by theoretical considerations. Contrary to plane waves in Cartesian coordinates, for which self-interacting terms are null in a linear stratifiation, the non-linear self-interaction of an internal wave mode in axisymmetric geometry is found to be efficient at producing super-harmonics, i.e. waves whose frequencies are integer multiples of the excitation frequency. Due to the range of frequencies tested in our experiments, the first harmonic frequency is below the cut-off imposed by the stratification so the lowest harmonic created can always propagate. The study shows that the super-harmonic wave field is a sum of standing waves satisfying both the dispersion relation for internal waves and the boundary conditions imposed by the cavity walls, while conserving the axisymmetry.

description: We have simulated the 3D emergence and interaction of two twisted flux tubes, which rise from the interior into the outer atmosphere of the Sun. We present evidence for the multiple formation and eruption of flux ropes inside the emerging flux systems and hot arcade-like structures in between them. Their formation is due to internal reconnection, occurring between oppositely directed, highly stretched and sheared fieldlines at photospheric heights. Most of the eruptions escape into the corona, but some are confined and fade away without leaving the low atmosphere. As these flux ropes erupt, new reconnected fieldlines accumulate around the main axis of the initial magnetic flux systems. We also show the complex 3D fieldline geometry and the structure of the multiple current sheets, which form as a result of the reconnection between the emerging flux systems.

The soft fermion dispersion relation at next-to-leading order in hot QED

Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study next-to-leading order contributions to the soft static fermion dispersion relation in hot QED. We derive an expression for the complete next-to-leading order contribution to the retarded fermion self-energy. The real and imaginary parts of this expression give the next-to-leading order contributions to the mass and damping rate of the fermionic quasi-particle. Many of the terms that are expected to contribute according to the traditional power counting argument are actually subleading. We explain why the power counting method over estimates the contribution from these terms. For the electron damping rate in QED we obtain: $γ_{QED} = \frac{e^2 T}{4π}(2.70)$. We check our method by calculating the next-to-leading order contribution to the damping rate for the case of QCD with two flavours and three coulours. Our result agrees with the result obtained previously in the literature. The numerical evaluation of the nlo contribution to the mass is left to a future publication.

description: We present Spitzer IRAC images, along with representative 5.27 to 38.5 micron IRS spectra of the Cassiopeia A supernova remnant. We find that various IRAC channels are each most sensitive to a different spectral and physical component. Channel 1 (3.6 micron) matches radio synchrotron images. Where Channel 1 is strong with respect to the other channels, the longer-wavelength spectra show a broad continuum gently peaking around 26 micron, with weak or no lines. We suggest that this is due to un-enriched progenitor circumstellar dust behind the outer shock, processed by shock photons and electrons. Where Channel 4 (8 micron) is bright relative to the other IRAC channels, the long-wavelength spectra show a strong, 2-3 micron-wide peak at 21 micron, likely due to silicates and proto-silicates, as well as strong ionic lines of [Ar II], [Ar III], [S IV] and [Ne II]. In these locations, the dust and ionic emission originate from the explosion's O-burning layers. The regions where Channels 2 (4.5 micron) and 3 (5.6 micron) are strongest relative to Channel 4 show a spectrum that rises gradually to 21 micron, and then flattens or rises more slowly to longer wavelengths, along with higher ratios of [Ne II] to [Ar II]. Dust and ionic emission in these locations arise primarily from the C- and Ne- burning layers. These findings are consistent with asymmetries in the explosion producing variations in the velocity structure in different directions, but preserving the nucleosynthetic layers. At each location, the dust and ionic lines in the mid-infrared, and the hotter and more highly ionized optical and X-ray emission are then dominated by the layer currently encountering the reverse shock in that direction.

Sparticle Discovery Potentials in the CMSSM and GUT-less Supersymmetry-Breaking Scenarios

description: We consider the potentials of the LHC and a linear e^+e^- collider (LC) for discovering supersymmetric particles in variants of the MSSM with soft supersymmetry-breaking mass parameters constrained to be universal at the GUT scale (CMSSM) or at some lower scale M_{in} (GUT-less models), as may occur in some scenarios with mirage unification. Whereas the LHC should be able to discover squarks and/or gluinos along all the CMSSM coannihilation strip where the relic neutralino LSP density lies within the range favoured for cold dark matter, many GUT-less models could escape LHC detection. In particular, if M_{in} < 10^{11} GeV, the LHC would not detect sparticles if the relic density lies within the favoured range. For any given discovery of supersymmetry at the LHC, in such GUT-less models the lightest neutralino mass and hence the threshold for sparticle pair production at a LC increases as M_{in} decreases, and the CMSSM offers the best prospects for measuring sparticles at a LC. For example, if the LHC discovers sparticles with 1 fb^{-1} of data, within the CMSSM a centre-of-mass energy of 600 GeV would suffice for a LC to to produce pairs of neutralinos, if they provide the cold dark matter, whereas over 1 TeV might be required in a general GUT-less model. These required energies increase to 800 GeV in the CMSSM and 1.4 TeV in GUT-less models if the LHC requires 10 fb^{-1} to discover supersymmetry.

description: The unitary isobar model MAID is used for a partial wave analysis of pion photoproduction and electroproduction data on the nucleon. In particular we have taken emphasis on the region of the Delta(1232) resonance and have separated the resonance and background amplitudes with the K-matrix approach. This leads to electromagnetic properties of the dressed Delta resonance, where all multipole amplitudes become purely imaginary and all form factors and helicity amplitudes become purely real at the K-matrix pole of W=M_Delta=1232 MeV. The REM=E2/M1 and RSM=C2/M1 ratios of the quadrupole excitation are compared to recent data analysis of different groups. The REM ratio of MAID2005 agrees very well with the data and has a linear behavior over the whole experimentally explored Q^2 region with a small positive slope that predicts a zero crossing around 3.5 GeV^2. The recent RSM data for Q^2 < 0.2 GeV^2 indicate a qualitative change in the shape of the ratio which can be explained by the impact of the Siegert theorem at pseudothreshold (Q^2=-0.086 GeV^2) in the unphysical region.

Treaty-making from an indigenous perspective : a ned’u’ten-canadian treaty model
Creators: name: McCue, Lorna June
Publisher: name: University of British Columbia
Year: 2009

description: This thesis argues that the Ned'u'ten, an indigenous people, have the right to decolonize and self-determine their political and legal status at the international level. The Ned'u'ten are currently negotiating a new relationship with Canada and are considering various treaty models to achieve this goal. This thesis advocates principles for a peace treaty model that accomplishes both Ned'u'ten decolonization and self-determination. The first chapter of this thesis demonstrates that indigenous perspectives in legal culture are diverse and not homogeneous. My Ned'u'ten perspective on treaty-making contributes to these perspectives. The second chapter challenges the legitimacy of the Canadian state, over Ned'u'ten subjects and territories. This is accomplished through the rejection of dispossession doctrines that Canada has used to justify colonial and oppressive practices against the Ned'u'ten. Decolonization principles are prescribed in this chapter. The third chapter takes a historical view of the right to self-determination and shows how state practice, indigenous peoples' participation, and international scholars have attempted to articulate the scope and content of this right in the contemporary context of indigenous self-determination. A Ned'u'ten self-determination framework is proposed based on indigenous formulations of the right to self-determination. Self-determination principles are also prescribed in this chapter. The final chapter compares two cases where indigenous peoples in Canada are attempting to create a new relationship with the state: the James Bay Cree and "First Nations" in the British Columbia Treaty Commission Process. This comparison will show that the degree of participation that indigenous peoples have in implementing their rights to self-determination, will determine the parameters of any new relationship that indigenous peoples create with the state. Negotiating principles are prescribed for a Ned'u'ten-Canada relationship as well as a peace treaty process to accomplish this goal. It is my thesis that the Ned'u'ten and Canada can achieve a peaceful and balanced relationship through the peace treaty model I propose.

description: We solve a model of phase separation among two competing phases frustrated by the long-range Coulomb interaction in two and three dimensions (2D/3D) taking into account finite compressibility effects. In the limit of strong frustration in 2D, we recover the results of R. Jamei, S. Kivelson, and B. Spivak, Phys. Rev. Lett. 94, 056805 (2005) and the system always breaks into domains in a narrow range of densities, no matter how big is the frustration. For weak frustration in 2D and for arbitrary frustration in 3D the finite compressibility of the phases is shown to play a fundamental role. Our results clarify the different role of screening in 2D and 3D systems. We discuss the thermodynamic stability of the system near the transition to the phase separated state and the possibility to observe it in real systems.

description: I offer some historical comments about the origins of Feynman's path integral approach, as an alternative approach to standard quantum mechanics. Looking at the interaction between Einstein and Feynman, which was mediated by Feynman's thesis supervisor John Wheeler, it is argued that, contrary to what one might expect, the significance of the interaction between Einstein and Feynman pertained to a critique of classical field theory, rather than to a direct critique of quantum mechanics itself. Nevertheless, the critical perspective on classical field theory became a motivation and point of departure for Feynman's space-time approach to non-relativistic quantum mechanics.

description: We consider a model with gauged $L_μ- L_τ$ symmetry in which the symmetry is spontaneously broken by a scalar field. The decay of the scalar boson into two new gauge bosons is studied as a direct consequence of the spontaneous symmetry breaking. Then, a possibility of searches for the gauge and scalar bosons through such a decay at the LHC experiment is discussed. We consider the case that the mass range of the gauge boson is $\mathcal{O}(10)$ GeV, which is motivated by anomalies reported by LHCb. We will show that the signal significance of the searches for the gauge boson and scalar boson reach to $3$ and $5$ for the scalar mixing $0.012$ and $0.015$, respectively.

description: The flux of hypothetical "hidden photons" from the Sun is computed under the assumption that they interact with normal matter only through kinetic mixing with the ordinary standard model photon. Requiring that the exotic luminosity is smaller than the standard photon luminosity provides limits for the mixing parameter down to 10^-14, depending on the hidden photon mass. Furthermore, it is pointed out that helioscopes looking for solar axions are also very sensitive to hidden photons. The recent results of the CAST collaboration are used to further constrain the mixing parameter at low masses m<1 eV where the luminosity bound is weaker. In this regime the solar hidden photon flux has a sizable contribution of longitudinally polarized hidden photons of low energy which are invisible for current helioscopes.

A Type-Oriented Graph500 Benchmark

description: Data intensive workloads have become a popular use of HPC in recent years and the question of how data scientists, who might not be HPC experts, can effectively program these machines is important to address. Whilst using models such as Partitioned Global Address Space (PGAS) is attractive from a simplicity point of view, the abstractions that these impose upon the programmer can impact performance. We propose an approach, type-oriented programming, where all aspects of parallelism are encoded via types and the type system which allows for the programmer to write simple PGAS data intensive HPC codes and then, if they so wish, tune the fundamental aspects by modifying type information. This paper considers the suitability of using type-oriented programming, with the PGAS memory model, in data intensive workloads. We compare a type-oriented implementation of the Graph500 benchmark against MPI reference implementations both in terms of programmability and performance, and evaluate how orienting their parallel codes around types can assist in the data intensive HPC field.

description: The isobar models eta-MAID and eta'-MAID have been used to analyze new data on quasi-free eta photoproduction on the deuteron from Bonn and recent eta' data on the proton from Jlab. In eta photoproduction on the neutron a bump around W=1700 MeV was observed which could possibly arise from a narrow P11 state that is discussed as a non-strange member of the Theta^+ anti-decuplett. In eta' photoproduction on the proton resonance contributions are found that can be attributed to missing resonances in the energy region around W=1900 MeV.

description: In this paper, we survey the rich theory of infinite episturmian words which generalize to any finite alphabet, in a rather resembling way, the well-known family of Sturmian words on two letters. After recalling definitions and basic properties, we consider episturmian morphisms that allow for a deeper study of these words. Some properties of factors are described, including factor complexity, palindromes, fractional powers, frequencies, and return words. We also consider lexicographical properties of episturmian words, as well as their connection to the balance property, and related notions such as finite episturmian words, Arnoux-Rauzy sequences, and "episkew words" that generalize the skew words of Morse and Hedlund.

description: In this paper, we study combinatorial and structural properties of a new class of finite and infinite words that are 'rich' in palindromes in the utmost sense. A characteristic property of so-called "rich words" is that all complete returns to any palindromic factor are themselves palindromes. These words encompass the well-known episturmian words, originally introduced by the second author together with X. Droubay and G. Pirillo in 2001. Other examples of rich words have appeared in many different contexts. Here we present the first unified approach to the study of this intriguing family of words. Amongst our main results, we give an explicit description of the periodic rich infinite words and show that the recurrent balanced rich infinite words coincide with the balanced episturmian words. We also consider two wider classes of infinite words, namely "weakly rich words" and almost rich words (both strictly contain all rich words, but neither one is contained in the other). In particular, we classify all recurrent balanced weakly rich words. As a consequence, we show that any such word on at least three letters is necessarily episturmian; hence weakly rich words obey Fraenkel's conjecture. Likewise, we prove that a certain class of almost rich words obeys Fraenkel's conjecture by showing that the recurrent balanced ones are episturmian or contain at least two distinct letters with the same frequency. Lastly, we study the action of morphisms on (almost) rich words with particular interest in morphisms that preserve (almost) richness. Such morphisms belong to the class of "P-morphisms" that was introduced by A. Hof, O. Knill, and B. Simon in 1995.

Distributed Nash Equilibrium Seeking for Monotone Generalized Noncooperative Games by a Regularized Penalty Method

description: In this work, we study the distributed Nash equilibrium seeking problem for monotone generalized noncooperative games with set constraints and shared affine inequality constraints. A distributed regularized penalty method is proposed. The idea is to use a differentiable penalty function with a time-varying penalty parameter to deal with the inequality constraints. A time-varying regularization term is used to deal with the ill-poseness caused by the monotonicity assumption and the time-varying penalty term. The asymptotic convergence to the least-norm variational equilibrium of the game is proven. Numerical examples show the effectiveness and efficiency of the proposed algorithm.
Moduli stabilization and uplifting with dynamically generated F-terms

description: We use the F-term dynamical supersymmetry breaking models with metastable vacua in order to uplift the vacuum energy in the KKLT moduli stabilization scenario. The main advantage compared to earlier proposals is the manifest supersymmetric treatment and the natural coexistence of a TeV gravitino mass with a zero cosmological constant. We argue that it is generically difficult to avoid anti de-Sitter supersymmetric minima, however the tunneling rate from the metastable vacuum with zero vacuum energy towards them can be very suppressed. We briefly comment on the properties of the induced soft terms in the observable sector.

$SU(5)$ GUTs with $A_4$ modular symmetry

description: We combine $SU(5)$ Grand Unified Theories (GUTs) with $A_4$ modular symmetry and present a comprehensive analysis of the resulting quark and lepton mass matrices for all the simplest cases. Classifying the models according to the representation assignments of the matter fields under $A_4$, we find that there are seven types of $SU(5)$ models with $A_4$ modular symmetry. We present 53 benchmark models with the fewest free parameters. The parameter space of each model is scanned to optimize the agreement between predictions and experimental data, and predictions for the masses and mixing parameters of quarks and leptons are given at the best fitting points. The best fit predictions for the leptonic CP violating Dirac phase, the lightest neutrino mass and the neutrinoless double beta decay parameter when displayed graphically are observed to cover a wide range of possible values, but are clustered around particular regions, allowing future neutrino experiments to discriminate between the different types of models.

Statistical Analysis of Crossed Undulator for Polarization Control in a SASE FEL

description: There is a growing interest in producing intense, coherent x-ray radiation with an adjustable and arbitrary polarization state. In this paper, we study the crossed undulator scheme (K.-J. Kim, Nucl. Instrum. Methods A {\bf 445}, 329 (2000)) for rapid polarization control in a self-amplified spontaneous emission (SASE) free electron laser (FEL). Because a SASE source is a temporally chaotic light, we perform a statistical analysis on the state of polarization using FEL theory and simulations. We show that by adding a small phase shifter and a short (about 1.3 times the FEL power gain length), $90^\circ$ rotated planar undulator after the main SASE planar undulator, one can obtain circularly polarized light -- with over 80% polarization -- near the FEL saturation.

description: Kinetochore (KTs) are macromolecular protein assemblies that attach sister chromatids to spindle microtubules (MTs) and mediate accurate chromosome segregation during mitosis. The outer KT consists of the KMN network, a protein super-complex comprising Knl1 (yeast Spc105), Mis12 (yeast Mtw1), and Ndc80 (yeast Ndc80), which harbours sites for MT binding. Within the KMN network, Spc105 acts as an interaction hub of components involved in spindle assembly checkpoint (SAC) signalling. It is known that Spc105 forms a complex with KT component Kre28. However, where Kre28 physically localizes in the budding yeast KT is not clear. The exact function of Kre28 at the KT is also unknown. Here, we investigate how Spc105 and Kre28 interact and how they are organized within bioriented yeast KTs using genetics and cell biological experiments. Our microscopy data show that Spc105 and Kre28 localize at the KT with a 1 : 1 stoichiometry. We also show that the Kre28-Spc105 interaction is important for Spc105 protein turn-over and essential for their mutual recruitment at the KTs. We created several truncation mutants of kre28 that affect Spc105 loading at the KTs. When over-expressed, these mutants sustain the cell viability, but SAC signalling and KT biorientation are impaired. Therefore, we conclude that Kre28 contributes to chromosome biorientation and high-fidelity segregation at least indirectly by regulating Spc105 localization at the KTs.
Who are you calling a child? : the limits on street-involved youth using legal rights
Creators: name: Mayer, Elizabeth
Publisher: name: University of British Columbia

description: At any one time there are estimated to be between 300 and 500 young people involved in street life in Vancouver. Although between 40 and 50 per cent, leave the street life each year, the overall figure remains much the same. Living on the street increases the chances of the young person being involved in crime, such as prostitution or theft, and of suffering from drug addiction, violent assault or HIV. However, for many young people the street is preferable to what they have left behind. And even when living on the street becomes too difficult, getting off the street often appears impossible. This thesis considers one way of addressing the problems faced by young people on the street: the use of legal rights. In particular, it considers the limits on such young people using rights. First, under the two main theories of rights for children, the content of the rights is decided by adults on behalf of the child. Second, the liberal form of rights further restricts their use by street-involved youth due to the anti-statist and atomistic nature of this version of rights. Third, the dominant discourse of childhood constrains the use of rights by imposing familial structures on young people on the street and ignoring their views. Rather than suggesting new rights for street-involved youth, this thesis concentrates on strategies that might be of use for street-involved youth in overcoming these constraints. These are giving an active voice to young people; insisting that the individual characteristics of street-involved youth are taken fully into account; considering a variety of actions, some of which might seem contradictory, but which allow for maximum flexibility; trusting the decisions of young people on the street; and ensuring that street-involved youth are not seen as an isolated problem, but in the context of a wider picture of other people with similar problems, such as adult street people, lesbian and gay youth, welfare recipients and so on.
