National history curriculum : finding space for a critical global education
Creators: name: Hophan, Phillip Albert
Publisher: name: University of British Columbia
Year: 2011

description: This investigation provides important insights for how a critical model of global education might be incorporated within national history pedagogies, in the face of increasingly strident neoliberal policy making in education. The demand of teaching, learning and theorizing in the contemporary political environment of the United States or Canada exerts undue pressure on students, teachers, and educationalists in the name of standardization, assessment and global economic preparedness. This research illuminates the critical possibilities that lie in the cracks of such oppressive policies, possibilities that may encourage students and teachers to act more substantially in defense of a globally infused national history education. Numerous foundational definitions of global education and four emergent models are extracted from a survey of North American global education literature, since 1980. These models are located in the official national history and social studies curriculum of the state of California and the province of British Columbia, respectively. Neoliberal educational policymaking is examined for its bearing on the advancement of global education in these jurisdictions. Significant differences in findings in California and British Columbia are explicated. Freirean critical pedagogy is considered as a theoretical framework for students and teachers to employ in turning back the neoliberal tide, by finding and utilizing space within the official national history curriculum for the rooting of a critical global education.

description: We report on new X-ray and optical observations of PSR J2030+4415, a Gamma-ray Pulsar with an H$α$ bow shock. These data reveal the velocity structure of the bow shock apex and resolve unusual X-ray structure in its interior. In addition the system displays a very long, thin filament, extending at least $5^\prime$ at $\sim 130^\circ$ to the pulsar motion vector. Careful astrometry, compared with a short archival exposure, detects the pulsar proper motion at 85 mas yr$^{-1}$. With the H$α$ velocity structure this allows us to estimate the distance as $0.75$ kpc.

description: In odd space-time dimensions, the retarded solution of the massless wave equation has support not only on the light cone, but also inside it. At the same time, a free massless field should propagate at the speed of light. The apparent contradiction of these two features is resolved by the fact that the emitted part of the field in the wave zone depends on the history of motion up to the retarded moment of proper time. It is shown that in the case of circular motion with ultrarelativistic velocity, the main contribution to the radiation amplitude is made by a small interval of proper time preceding the retarded time, and thus the tail term is effectively localized. We obtain a tentative formula for scalar synchrotron radiation in $D$ dimensions: $P =g^2(ω_0γ^2/\sqrt{3})^{D-2}$, which is explicitly verified in $D=3,\,4,\,5$.

description: Man-made communications signals are typically modelled as continuous-time (CT) wide-sense cyclostationary (WSCS) processes. As modern processing is digital, it operates on sampled versions of the CT signals. When sampling is applied to a CT WSCS process, the statistics of the resulting discrete-time (DT) process depends on the relationship between the sampling interval and the period of the statistics of the CT process: When these two parameters have a common integer factor, then the DT process is WSCS. This situation is referred to as synchronous sampling. When this is not the case, which is referred to as asynchronous sampling, the resulting DT process is wide-sense almost cyclostationary (WSACS). In this work, we study the fundamental tradeoff of sources codes applied to sampled CT WSCS processes, namely, their rate-distortion function (RDF). We note that RDF characterization for the case of synchronous sampling directly follows from classic information-theoretic tools utilizing ergodicity and the law of large numbers; however, when sampling is asynchronous, the resulting process is not information stable. In such cases, commonly used information-theoretic tools are inapplicable to RDF analysis, which poses a major challenge. Using the information spectrum framework, we show that the RDF for asynchronous sampling in the low distortion regime can be expressed as the limit superior of a sequence of RDFs in which each element corresponds to the RDF of a synchronously sampled WSCS process (but their limit is not guaranteed to exist). The resulting characterization allows us to introduce novel insights on the relationship between sampling synchronization and RDF. For example, we demonstrate that, differently from stationary processes, small differences in the sampling rate and the sampling time offset can notably affect the RDF of sampled CT WSCS processes.

description: As an example for a seemingly simple but actually intricate problem, the Bean critical state is studied in a superconducting strip of finite thickness d and width 2w >> d placed in an oblique magnetic field. The analytical solution is obtained to leading order in the small parameter d/w. The critical state depends on how the applied magnetic field is switched on, e.g., at constant tilt angle, or first the perpendicular and then the parallel field component. For these two basic scenarios the distributions of current density and magnetic field are obtained in the critical states. In particular, we find the shapes of the flux-free core and of the lines separating regions with opposite direction of the critical currents, the detailed magnetic field lines (along the vortex lines), and both components of the magnetic moment. The component of the magnetic moment parallel to the strip plane is a nonmonotonic function of the applied magnetic field.

The ecology of identity : memoir and the construction of narrative
Creators: name: Armstrong, Luanne Aileen
Publisher: name: University of British Columbia
Year: 2010

description: My dissertation is an inquiry into issues of life-writing, narrative, and, in particular, into the genre of memoir, and into the theory, complexities and strategies of memoir as a particular space within the larger genre of autobiographical writing. Writing a personal narrative and then examining the process of that writing raises questions and challenges about such issues as ethics, identity, experience, memory, subjectivity, storytelling, and the interpretation, meaning and place of stories within our current culture. This dissertation is a discursive, dialogic conversation between my process and my understanding as an active, practicing literary writer, and as a researcher inquiring into that process and into the knowledge and new awareness that can be generated by the process of inquiry into life writing, autobiography and memoir. It is also an autoethnographic and experiential inquiry in which I explore my own experience from the multiple positions of rural working class woman, single parent mother, political activist, writer and researcher. However, the pronoun "I" is also a position from which I can articulate some of the experiential, collaborative, and collusive positionality that has shaped my personal notion of selfhood. My research and writing is about (re)cognition, about memoir in particular, and narrative and storytelling as the construction and reconstruction of various texts and the various interpretations that can result from such an analytic and critical study of this process. Within this narrative, autobiographical and theoretical inquiry, my dissertation intends to add to new knowledge of autobiographical writing and its theoretical and ethical dimensions.
Imposing minimum and maximum member size, minimum cavity size, and minimum separation distance between solid members in topology optimization

description: This paper focuses on density-based topology optimization and proposes a combined method to simultaneously impose Minimum length scale in the Solid phase (MinSolid), Minimum length scale in the Void phase (MinVoid) and Maximum length scale in the Solid phase (MaxSolid). MinSolid and MinVoid mean that the size of solid parts and cavities must be greater than the size of a prescribed circle or sphere. This is ensured through the robust design approach based on eroded, intermediate and dilated designs. MaxSolid seeks to restrict the formation of solid parts larger than a prescribed size, which is imposed through local volume restrictions. In the first part of this article, we show that by proportionally restricting the maximum size of the eroded, intermediate and dilated designs, it is possible to obtain optimized designs satisfying, simultaneously, MinSolid, MinVoid and MaxSolid. However, in spite of obtaining designs with crisp boundaries, some results can be difficult to manufacture due to the presence of multiple rounded cavities, which are introduced by the maximum size restriction with the sole purpose of avoiding thick solid members in the structure. To address this issue, in the second part of this article we propose a new geometric constraint that seeks to control the minimum separation distance between two solid members, also called the Minimum Gap (MinGap). Differently from MinVoid, MinGap introduces large void areas that do not necessarily have to be round. 2D and 3D test cases show that simultaneous control of MinSolid, MinVoid, MaxSolid and MinGap can be useful to improve the manufacturability of maximum size constrained designs.

Abseits der Universität musste ich ziemlich schnell lernen, dass kein Thema mehr Anlass zur Diskussion bereitet als Kosten, und, dass der schönste Entwurf über das Entwurfsstadium nicht hinaus kommt, wenn diese außer Acht gelassen werden. Abgesehen davon hält sich das Argument, ein Architekt mache alles kompliziert und teuer ziemlich hartnäckig in der Bevölkerung. Ein Fertigteilhaus sei nicht mehr so schlecht wie ihr Ruf und außerdem viel günstiger, schließlich könne man schon bei der Planung einiges an Geld sparen. Über Ersteres kann man streiten, per se schlecht sind sie aber defi nitiv nicht, und schnell aufgebaut sind sie auch. Aber stimmt es, dass sie günstiger sind? Und kann man wirklich bei der Planung sparen und sich den Gang zum Architekten ersparen? Vielleicht sollte man die Fragen anders formulieren. Kann ein Architekt mit einem individuellen Entwurf, der eine höhere gestalterische Qualität bietet, am Ende sogar Kosten und Bauzeit einsparen?

Apart from that the prejudice, an architect makes everything expensive and complicated keeps in everybodys head. Precast houses are not as bad as in earlier days and they are cheaper anyway, because you can save cost in planning already. For the former you can discus, bad quality in general isnt given defi nitely and they are built up fast also. But are they really cheaper? And can you really save money on planning und dont need an architect? Maybe you should ask the question differently. Can an architect offer you higher quality with an individual design and even save money and time in building a house?

description: The effect of a random surface field, within the bimodal distribution, on the layering transitions in a spin-1/2 Ising thin film is investigated, using Monte Carlo simulations. It is found that the layering transitions depend strongly on the concentration $p$ of the disorder of the surface magnetic field, for a fixed temperature, surface and external magnetic fields. Indeed, the critical concentration $p_c(k)$ at which the magnetisation of each layer $k$ changes the sign discontinuously, decreases for increasing the applied surface magnetic field, for fixed values of the temperature $T$ and the external magnetic field $H$. Moreover, the behaviour of the layer magnetisations as well as the distribution of positive and negative spins in each layer, are also established for specific values of $H_s$, $H$, $p$ and the temperature $T$. \\

description: In this paper, we present a model describing the time evolution of two dimensional surface waves in gravity and infinite depth. The model of six interacting modes derives from the normal form of the system describing the dynamics of surface waves and is governed by a Hamiltonian system of equations of cubic order in the amplitudes of the waves. We derive a Hamiltonian system with two degrees of freedom from this Hamiltonian using conserved quantities. The interactions are those of two coupled Benjamin-Feir resonances. The temporal evolution of the amplitude of the different modes is described according to the parameters of the system. In particular, we study the energy exchange produced by the modulations of the amplitudes of the modes. The evolution of the modes reveals a chaotic dynamics.

description: We examine several issues pertaining to statistical predictivity of the string theory landscape for weak scale supersymmetry (SUSY). We work within a predictive landscape wherein super-renormalizable terms scan while renormalizable terms do not. We require stringy naturalness wherein the likelihood of values for observables is proportional to their frequency within a fertile patch of landscape including the MSSM as low energy effective theory with a pocket-universe value for the weak scale nearby to its measured value in our universe. In the string theory landscape, it is reasonable that the soft terms enjoy a statistical power-law draw to large values, subject to the existence of atoms as we know them (atomic principle). We argue that gaugino masses, scalar masses and trilinear soft terms should each scan independently. In addition, the various scalars should scan independently of each other unless protected by some symmetry. The expected non-universality of scalar masses-- once regarded as an undesirable feature-- emerges as an asset within the context of the string landscape picture. In models such as heterotic compactifications on Calabi-Yau manifolds, where the tree-level gauge kinetic function depends only on the dilaton, then gaugino masses may scale mildly, while scalar masses and A-terms, which depend on all the moduli, may scale much more strongly leading to a landscape solution to the SUSY flavor and CP problems in spite of non-diagonal Kähler metrics. We present numerical results for Higgs and sparticle mass predictions from the landscape within the generalized mirage mediation SUSY model and discuss resulting consequences for LHC SUSY and WIMP dark matter searches.

description: We modeled the spectral energy distribution (SED) of high redshift radio quiet quasars (high-z RQQs). We computed spectra in a patchy corona geometry where an accretion disk extends to the last stable orbit and the Comptonizing active regions (hot clouds) are distributed above the disk. We explored the model parameter space to find theoretical parameters that give spectra with the optical/UV luminosity, the X-ray loudness, and the X-ray photon index compatible with those of high-z RQQs observed with Chandra. We found that a range of solutions is possible, from high-$kT_{\rm e}$ low-$τ$ to low-$kT_{\rm e}$ high-$τ$ models. The solutions require low level of energy dissipation in the hot clouds and low disk covering factor. The modeled mass is of the order of $10^{10}$ Solar masses and the accretion rate is $\dot{M} > 0.2$ Eddington rate. We compare our results to those obtained previously for hot inner flow geometry.

Necessary statements about quaternion manifolds with quaternion holomorphic transition mappings between charts of atlases are proved. Unitary representations of these groups including irreducible are constructed with the help of stochastic processes and quasi-invariant transition measures on groups $G$ relative to dense subgroups $G'$. It is proved, that this procedure provides a family of the cardinality $card ({\bf R})$ of pairwise nonequivalent irreducible unitary representations. A differentiability of such representations is studied.

Publisher: name: University of British Columbia
Year: 2010

description: My dissertation is a selection of essays that reflect upon human potential, particularly but not exclusively, within educational environments. I offer theory and practices that suggest that under the right conditions educators and students will move towards the far reaches of their own creative capacities. I offer my own experience and practice as an exemplar of possibilities. I make proposals about educators and education of educators that represent a paradigm shift from centralizing curriculum and content to focusing on care, nurturance, subjective and inter-subjective understanding, and development of educators. The reader is invited to see educators as central, and is encouraged towards the possibility that educators must be supported, encouraged, and cared for in order to support emergence of their vitality, first for themselves and subsequently for students. I outline an approach that puts human beings in educational environments first in practical and specific ways. Integration of personal experience and curriculum material is explicated. The importance of personal inner work for educators is highlighted. Inner Work is characterized as a personal and spiritual process. The claim that educators need to have group facilitation skills is made and evidence offered. Philosophical and theoretical background from education, eastern and western philosophy, humanistic and transpersonal psychology, process-oriented methods, and counselling psychology are drawn upon. The approach is holistic and systemic. The human is viewed as important but not separate from other living beings or the environment. The values of presence, care, and deep democracy underlie the ideas. The importance of relationality and I-Thou connection are explicated. The writing and research draws on a variety of qualitative approaches, including, living inquiry, autobiography, and self-study, as well as conceptual, narrative, poetic, auto-ethnographic, heuristic, and analytic methods. The material, personal, and ephemeral are investigated as integrated parts of the Dao-Field of education and life.

description: Objective: For real-time markerless tumour tracking in stereotactic lung radiotherapy, we propose a different approach which uses patient-specific deep learning (DL) using a personalized data generation strategy, avoiding the need for collection of a large patient data set. We validated our strategy with digital phantom simulation and epoxy phantom studies. Methods: We developed lung tumour tracking for radiotherapy using a convolutional neural network trained for each phantom's lesion by using multiple digitally reconstructed radiographs (DRRs) generated from each phantom's treatment planning 4D-CT. We trained tumour-bone differentiation using large numbers of training DRRs generated with various projection geometries to simulate tumour motion. We solved the problem of using DRRs for training and X-ray images for tracking by using the training DRRs with random contrast transformation and random noise addition. Results: We defined adequate tracking accuracy as the % frames satisfying < 1 mm tracking error of the isocentre. In the simulation study, we achieved 100% tracking accuracy in 3-cm spherical and 1.5 x 2.25 x 3-cm ovoid masses. In the phantom study, we achieved 100% and 94.7% tracking accuracy in 3- and 2-cm spherical masses, respectively. This required 32.5 ms/frame (30.8 fps) real-time processing. Conclusions: We proved the potential feasibility of a real-time markerless tumour tracking framework for stereotactic lung radiotherapy based on patient-specific DL with personalized data generation with digital phantom and epoxy phantom studies. Advances in Knowledge: Using DL with personalized data generation is an efficient strategy for real-time lung tumour tracking.

description: For any metric space $X$, finite subset spaces of $X$ provide a sequence of isometric embeddings $X=X(1)\subset X(2)\subset\cdots$. The existence of Lipschitz retractions $r_n\colon X(n)\to X(n-1)$ depends on the geometry of $X$ in a subtle way. Such retractions are known to exist when $X$ is an Hadamard space or a finite-dimensional normed space. But even in these cases it was unknown whether the sequence $\{r_n\}$ can be uniformly Lipschitz. We give a negative answer by proving that $\operatorname{Lip}(r_n)$ must grow with $n$ when $X$ is a normed space or an Hadamard space.

description: We report on the intershell electron transport in multiwalled carbon nanotubes (MWNT). To do this, local and nonlocal four-point measurements are used to study the current path through the different shells of a MWNT. For short electrode separations $\lesssim$ 1 $μ$m the current mainly flows through the two outer shells, described by a resistive transmission line with an intershell conductance per length of ~(10 kΩ)^{-1}/$μ$m. The intershell transport is tunnel-type and the transmission is consistent with the estimate based on the overlap between $π$-orbitals of neighboring shells.

description: Magyarország az 1980-as évekig magas színvonalú lovasturizmusáról volt nevezetes. Az évtized végén kezdődő privatizáció ezt a szektort sem kerülte el. A szolgáltatások színvonala az addig megszokott alá csökkent, az árak az egekbe szöktek, a szolgáltatások iránti kereslet szerkezete megváltozott. A kedvezőtlen folyamatok ellenére egyre többen kezdtek lovasturisztikai szolgáltatásba, amit kellő szabályozottság hiányában bárki, akinek pénze volt, megtehetett. A hazai lovasszakma máig legnagyobb problémája a hatósági szabályozás hiánya. Megoldásra vár egy többszintű szakképzési-oktatási rendszer kidolgozása, a lovak szakmai minősítési rendszerének kidolgozása, a már működő patkós minősítési rendszer működésének hatékonyabbá tétele, a szabad tereplovaglás feltételeinek megteremtése. A Széchenyi Turizmusfejlesztési Program Lovasturizmus Fejlesztési Alprogramjának célja a lovasturizmus fogadófeltételeinek javítása, a kereslet élénkítése és az ágazat bevételeinek növelése. Ezen célkitűzéseknek megfelelően a tavalyi évben elkészült az Észak-Magyarországi Régió és az Észak- Alföldi Régió lovasturisztikai termékfejlesztési programja, mely mintául szolgálhat a többi régió ezirányú fejlesztéseihez. ----------------- Till the eighties of the previous century Hungary was renowned for the high standard of her equestrian tourism. Privatisation which had begun at the end of that decade did not avoid this sector either. Subsequently, the standard of services has dropped along with an enormous increase in prices, and the structure of demand for services has changed. In spite of these unfavourable processes more and more people have started equestrian tourism services, which anybody was allowed to do who could afford it because regulation was lacking. This lack of official regulation is still the main problem of the equestrian profession in Hungary. Some other tasks to be solved are: the establishment of multi-level vocational training; the elaboration of a system of professional qualification for horses; the increasing of the efficiency of the already existing horseshoe qualification system; and the creation of the prerequisites of free cross-country ride. The objects of the Sub-programme of the Development of Equestrian Tourism, a sub-programme of the Széchenyi Programme of the Development of Tourism, are: to improve the conditions of accepting guests for equestrian tourism; to intensify demand; and to increase income for the sector. In accord with these objects the programme of developing equestrian tourism products for the Northern Hungarian Region and the Northern Great Plain Region was elaborated in 2003. It can serve as a model for an analogous development in the rest of the regions of Hungary.

description: A kereskedelem pozícióját befolyásoló tényezők, a kereskedelem szerkezetében tapasztalható változások, valamint a piackutatók előrejelzései alapján hazánkban is érvényesülni látszanak az európai trendek (5): – A nagyok egyre nagyobbak lesznek, jellemző a multinacionális konszernek részesedésének további emelkedése. – Az üzletek polarizálódnak, a közepes árfekvésű boltok veszítenek szerepükből, erősödik az alsó árpiaci szegmens és a minőségvezető stratégiát folytató cégek szerepe. – Terjed a kereskedelmi cégek diverzifikációja, jellemző az új termékcsoportok, új üzlettípusok, új országok felé fordulás. – Nő a kereskedelmi márkák száma és szerepe. – Nő a vásárlók öntudata, növekednek elvárásaik, és ezeknek hangot is adnak. – A friss árú iránt az igény fokozódik, ami a boltok számára komoly logisztikai problémát jelent. – A logisztikai feladatok minél hatékonyabb megoldása egyre jelentősebb versenytényezővé válik. – Várható az információhasználat fejlődése. – A bolton belüli innovációk új megoldásokat eredményeznek a POS befolyásolás, az árú prezentáció területén. – A gyártó-kereskedő kapcsolat javul, a hosszú távú együttműködés fontosságát egyre többen ismerik fel. ---------------- Factors influencing the position of trade, changes in its structure, and prognoses of market researchers indicate that following trends already prevailing in Europe seem to manifest themselves also in Hungary: – The big are becoming bigger and bigger, whereas further increase in the ratio of multi-national concerns is characteristic. – Shops are polarising, i. e. the role of shops of medium price level is decreasing along with an increase in the importance of the lower price market segment, and in the role of companies practising the strategy of quality guidance. – The diversification of commercial companies is increasing. Characteristic of this phenomenon is their turn towards new product groups, new shop types, and new countries. – The number and role of trade marks is increasing. – The self-consciousness of goodwill is increasing, along with their expectations, to which they also give utterance. – Requirements for fresh products are increasing, which is a serious problem of shops in the field of logistics. – To solve tasks in the field of logistics as perfectly as possible is becoming a more and more important factor of competition. – The development of information use can be expected. – Innovation within shops results in new solutions in the field of POS influence and commodity presentation. – Contacts between producers and traders are improving; more and more people become aware of the importance of long-term collaboration.
Gendering the body : an autobiographical narrative inquiry into the pedagogy of family rituals
Creators: name: Stubbs, Jean

description: My thesis is an inquiry into issues of narrative, childhood history, gender and the body. In particular it offers a critical inquiry into the pedagogy of family rituals. Supporting this endeavour I marshal the theoretical strengths of feminist theory and heuristic writing pertaining to autobiographical narrative to conduct this research. Writing and examining personal narratives raises questions and challenges about issues of voice, gender, history, and the interpretation, meaning and value of narrative within our current culture. It is an autoethnographic and experiential inquiry in which I explore my own childhood experience from the perspectives of New Zealand small town girl, Canadian urban middle class woman, remarried mother, wife, teacher, writer and researcher. This thesis is an expression of my desire to re(discover) and address the positions I occupied in childhood as they shaped my personal notion of gender. The process of writing myself undresses and re(dresses) the child I once was. Through autobiographical narratives and theoretical inquiry, my thesis demonstrates the potential of autobiographical writing to reveal how the history of childhood and the pedagogy of family rituals shape the experience of becoming a gendered body.

description: Mammal sex allocation research has focused almost exclusively on maternal traits, but it is now apparent that fathers can also influence offspring sex ratios. Parents that produce female offspring under conditions of the intense male–male competition can benefit with greater assurance of maximized grand-parentage. Adaptive adjustment in the sperm sex ratio, for example with an increase in the production of X-chromosome bearing sperm (CBS), is one potential paternal mechanism for achieving female-biased sex ratios. Here, we tested this mechanistic hypothesis by varying the risk of male–male competition that male house mice perceived during development, and quantifying sperm sex ratios at sexual maturity. Our analyses revealed that males exposed to a competitive ‘risk’ produced lower proportions of Y-CBS compared to males that matured under ‘no risk’ of competition. We also explored whether testosterone production was linked to sperm sex ratio variation, but found no evidence to support this. We discuss our findings in relation to the adaptive value of sperm sex ratio adjustments and the role of steroid hormones in socially induced sex allocation.

description: High entropy oxides (HEOs) are single phase solid solutions consisting of 5 or more cations in approximately equiatomic proportions. In this study, we show reversible control of optical properties in a rare-earth (RE) based HEO-(Ce$_{0.2}$La$_{0.2}$Pr$_{0.2}$Sm$_{0.2}$Y$_{0.2}$)O$_{2-δ}$ and subsequently utilize a combination of spectroscopic techniques to derive the features of the electronic band structure underpinning the observed optical phenomena. Heat treatment of the HEO under vacuum atmosphere followed by reheat-treatment in air results in a reversible change of the band gap energy, from 1.9 eV to 2.5 eV. The finding is consistent with the reversible changes in the oxidation state and related $f$-orbital occupancy of Pr. However, no pertinent changes in the phase composition or crystal structure is observed upon the vacuum heat treatment. Further annealing of this HEO under H$_2$ atmosphere, followed by reheat-treatment in air, results in even larger but still reversible change of the band gap energy from 1.9 eV to 3.2 eV. This is accompanied by a disorder-order type crystal structure transition and changes in the O 2$p$-RE 5$d$ hybridization evidenced from X-ray absorption near edge spectra (XANES). The O $K$ and RE ${M_{4,5}}$/$L_{3}$ XANES indicate that the presence of Ce and Pr (in 3+/4+) state leads to the formation of intermediate 4$f$ energy levels between the O 2$p$ and RE 5$d$ gap in HEO. It is concluded that heat treatment under reducing/oxidizing atmospheres affects these intermediate levels, thus, offering the possibility to tune the band gap energy in HEO.

description: We find that sudden future singularities may also appear in spatially inhomogeneous Stephani models of the universe. They are temporal pressure singularities and may appear independently of the spatial finite density singularities already known to exist in these models. It is shown that the main advantage of the homogeneous sudden future singularities which is the fulfillment of the strong and weak energy conditions may not be the case for inhomogeneous models.
