description: Positive effects of shared reading for children’s language development are boosted by including instruction of word meanings and by increasing interactivity. The effects of engaging children as storytellers on vocabulary development have been less well studied. We developed an approach termed Interactive Elaborative Storytelling (IES), which employs both word-learning techniques and children’s storytelling in a shared-reading setting. To systematically investigate potential benefits of children as storytellers, we contrasted this approach to two experimental groups, an Elaborative Storytelling group employing word-learning techniques but no storytelling by children and a Read-Aloud group, excluding any additional techniques. The study was a 3 × 2 pre-posttest randomized design with 126 preschoolers spanning 1 week. Measured outcomes were receptive and expressive target vocabulary, story memory, and children’s behavior during story sessions. All three experimental groups made comparable gains on target words from pre- to posttest and there was no difference between groups in story memory. However, in the Elaborative Storytelling group, children were the least restless. Findings are discussed in terms of their contribution to optimizing shared reading as a method of fostering language.

description: Background: Some developer activity traditionally performed manually, such as making code commits, opening, managing, or closing issues is increasingly subject to automation in many OSS projects. Specifically, such activity is often performed by tools that react to events or run at specific times. We refer to such automation tools as bots and, in many software mining scenarios related to developer productivity or code quality it is desirable to identify bots in order to separate their actions from actions of individuals. Aim: Find an automated way of identifying bots and code committed by these bots, and to characterize the types of bots based on their activity patterns. Method and Result: We propose BIMAN, a systematic approach to detect bots using author names, commit messages, files modified by the commit, and projects associated with the ommits. For our test data, the value for AUC-ROC was 0.9. We also characterized these bots based on the time patterns of their code commits and the types of files modified, and found that they primarily work with documentation files and web pages, and these files are most prevalent in HTML and JavaScript ecosystems. We have compiled a shareable dataset containing detailed information about 461 bots we found (all of whom have more than 1000 commits) and 13,762,430 commits they created.

description: We suggest an experimentally feasible procedure to observe paired and counterflow superfluidity in ultra-cold atom systems. We study the time evolution of one-dimensional mixtures of bosonic atoms in an optical lattice following an abrupt displacement of an additional weak confining potential. We find that the dynamic responses of the paired superfluid phase for attractive inter-species interactions and the counterflow superfluid phase for repulsive interactions are qualitatively distinct and reflect the quasi long-range order that characterizes these phases. These findings suggest a clear experimental procedure for their detection, and give an intuitive insight into their dynamics.

description: This research set out to test the mediating of employee attitudes on the relationship between SHRM (Society for Human Resource Management) practices and organizational effectiveness in Palestinian banking sector. Using structural equation modeling (SEM) it is investigated a random sample of 357 Palestinian banks' employees selected in a random manner in 16 Palestinian governorates. The partial least square approach has been used depending on SMART-PLS software. Results show the existence of direct and indirect significant path between SHRM practices and organizational effectiveness. However, the indirect relationship through the mediating role of employee attitudes was stronger than the direct one. To sum up, results indicate that employee attitudes partially mediate the relationship between SHRM practices and organizational effectiveness.

description: The economic aspect of food security at The University of British Columbia was assessed by investigating perceived overall affordability of campus food items. Questionnaires regarding campus food establishments and participants’ purchasing habits were distributed randomly at high-traffic locations on campus. Seventy-eight percent of respondents rated the overall price of food at UBC as “moderately expensive” or “expensive” and 80% purchased food five times per week or less, leading us to conclude that overall food pricing is predominantly inappropriate for the UBC community. Short-term, intermediate, and long-term practical recommendations are proposed to facilitate achievement of UBC food security within a dynamic and evolving community.

description: We study entanglement in dimerized Heisenberg systems. In particular, we give exact results of ground-state pairwise entanglement for the four-qubit model by identifying a Z2 symmetry. Although the entanglements cannot identify the critical point of the system, the mean entanglement of nearest-neighbor qubits really does, namely, it reaches a maximum at the critical point.

description: This study performs an examination on the impact of public and private investment on economic growth and the crowding effect of public investment on private investment in Zimbabwe from 1970 to 2014. The study utilised the newly developed autoregressive distributed lag-bounds testing approach with better small sample properties than the traditional cointegration techniques. The results show that public investment has a higher short-run growth impact, but in the long run the private investment-led growth is more important. In addition, while gross public investment crowds out private investment, infrastructural public investment has a long-run crowding in effect. A non-infrastructural public investment was also reported to have a short-run crowding out effect on private investment. The results suggest that the productivity of public and private investment in Zimbabwe can be improved by cutting back on non-infrastructural public investment to basic minimum level while stimulating the growth in infrastructural public investment.
title: Embodied Ethics and Contemporary Paganism
Creators: name: Jamison, Ian
Publisher: name: The Open University
Year: 2011

description: Contemporary understandings of ethics consistently situate them as the result of a focussed rational and intellectual process within a narrow range of academic and religious areas. I challenge this approach, and theorise an embodied approach to ethics as both possible and desirable. I argue that such an approach may be most easily located in the contemporary Pagan approach to environmental ethics, given that the rhetoric of Paganism valorises the body and privileges the natural environment. While I agree that Paganism is indeed a nature religion, I theorise that there are two simultaneous yet contradictory discourses of nature informing Paganism: the animist (privileging nature qua nature) and the esoteric (privileging a symbolic understanding of nature). I assert that my qualitative fieldwork demonstrates that some Pagans have developed an embodied ethic through close relationship with nature. I acknowledge that the development of such a profound relationship requires considerable effort and a great deal of time. I then compare this against quantitative data from an online survey of self-identifying Pagans in order to establish the extent to which such an approach might be representative. The Initial analysis of the online data supports the assertion that my respondents are likely to express positive attitudes to the environment, but are unlikely to participate in activism in relation to a number of specified areas. Deeper analysis compares the data between different groups identified along the animist/esoteric scale, and suggests that those Pagans who are more influenced by the animist discourse are indeed more likely to express environmentally friendly attitudes and to take part in activism. I conclude that such an embodied environmental ethic is possible, although this may be substantially contingent upon lifestyle. I posit that by understanding the diversity of discourses informing Pagan approaches to nature, academics may be able to more accurately interpret the diversity of Pagan approaches, and Pagans themselves may be able to move forward in discussions between their various traditions.

description: While the floors of deep lunar craters are largely shielded from solar radiation and thus provide an ideal thermal environment for water ice accumulation, meteoroids on highly inclined orbits can easily access permanently shadowed regions and alter the surface properties via hyper-velocity impacts. Here we consider the detailed topography of lunar poles and a dynamical model of meteoroids to quantify the meteoroid mass fluxes, energy deposition, and impact ejecta mass production rates. Our analysis of regions within $5^\circ$ from the two lunar poles shows that the variations of the meteoroid mass flux, energy flux and ejecta production rate are within $50\%$ of their median values. We find that lunar poles are easily accessible by meteoroid impacts including permanently shadowed regions. We find a positive correlation between the surface slope and the meteoroid ejecta production rate, a finding that suggests a higher impact gardening rate on steep crater walls can facilitate mass wasting.

description: Ultracold ground state dipolar 40K87Rb molecules have recently been produced in a loose harmonic trap by employing a magnetic field sweep across a Feshbach resonance followed by stimulated Raman adiabatic passage [K.-K. Ni et al., Science 322, 231 (2008)]. The overall experimental efficiency for molecule formation was around 20%. We show that the efficiency can be increased to nearly 100% if one first loads the atomic gases into an optical lattice of the appropriate depth and tunes the interspecies attraction to have exactly one atom of each species at an occupied lattice site. Our proposed scheme provides a large enhancement to the dipolar molecule density even at relatively high temperatures, and avoids three-body recombination loss by preventing lattice sites from being triply occupied.

description: Pharmacological inhibition of the renin–angiotensin–aldosterone system (RAAS) is, in combination with diuretics, the first-choice treatment for hypertension, although 10–20% of patients do not respond adequately. Next to the RAAS, the nitric oxide/cGMP/protein kinase G (PKG) system is the second fundamental blood pressure regulator. Whether both systems influence each other is not well-studied. It has been shown that nitric oxide (NO) supports renin recruitment via activation of soluble guanylate cyclase (sGC) and subsequent generation of cGMP. Whether this leads to an ensuing activation of PKGs in this context is not known. PKGIα, as well as PKGII, is expressed in renin-producing cells. Hence, we analyzed whether these enzymes play a role regarding renin synthesis, secretion, or recruitment. We generated renin-cell-specific PKGI-knockout mice and either stimulated or inhibited the renin system in these mice by salt diets. To exclude the possibility that one kinase isoform can compensate the lack of the other, we also studied double-knockout animals with a conditional knockout of PKGI in juxtaglomerular cells (JG cells) and a ubiquitous knockout of PKGII. We analyzed blood pressure, renin mRNA and renal renin protein content as well as plasma renin concentration. Furthermore, we stimulated the cGMP system in these mice using BAY 41-8543, an sGC stimulator, and examined renin regulation either after acute administration or after 7 days (application once daily). We did not reveal any striking differences regarding long-term renin regulation in the studied mouse models. Yet, when we studied the acute effect of BAY 41-8543 on renin secretion in isolated perfused kidneys as well as in living animals, we found that the administration of the substance led to a significant increase in plasma renin concentration in control animals. This effect was completely abolished in double-knockout animals. However, after 7 days of once daily application, we did not detect a persistent increase in renin mRNA or protein in any studied genotype. Therefore, we conclude that in mice, cGMP and PKG are involved in the acute regulation of renin release but have no influence on long-term renin adjustment.

description: Since a large fraction of active galactic nuclei (AGN) is missed in common UV-excess surveys and is even hard to find in radio, near-IR and X-ray surveys, we have used a new AGN selection technique which is expected to be not affected by extinction. Within the scientific verification of the ISOCAM Parallel Survey at 6.7 micron we have discovered objects with exceptional mid-infrared (MIR) emission. They are essentially not detected on IRAS-ADDSCANs and only very few of them show up in the NVSS and FIRST radio surveys. Various colour criteria of the 6.7 micron data with 2MASS and optical wavebands show that the sources reach more extreme IR colours than the sources in the Hubble Deep Field-South and the ELAIS survey. The comparison with known object types suggests that we have found AGN with a pronounced MIR emission, probably due to circum-nuclear dust. First results from optical spectroscopy of ten candidates corroborate this interpretation showing four AGN, two reddened LINER and four extremely reddened emission-line galaxies with MIR/FIR flux ratios higher than for known pure starburst galaxies. The results will make a significant contribution to the debate on the entire AGN population.

description: We study the noise correlations of one-dimensional binary Bose mixtures, as a probe of their quantum phases. In previous work [23], we found a rich structure of many-body phases in such mixtures, such as paired and counterflow superfluidity. Here we investigate the signature of these phases in the noise correlations of the atomic cloud after time-of-flight expansion, using both Luttinger liquid theory and the time-evolving block decimation (TEBD) method. We find that paired and counterflow superfluidity exhibit distinctive features in the noise spectra. We treat both extended and inhomogeneous systems, and our numerical work shows that the essential physics of the extended systems is present in the trapped-atom systems of current experimental interest. For paired and counterflow superfluid phases, we suggest methods for extracting Luttinger parameters from noise correlation spectroscopy.

description: Brahmaputra silt from the Nimati Ghat area (South Bank of Brahmaputra) with locational coordinates (26.86Lat. 94.22Long.) in the Jorhat district of Assam has been collected to study the engineering properties and to propose a possible improvement to its engineering properties. The collected specimen of Brahmaputra silt was non plastic and exhibited a Liquid Limit of 33.80%, Maximum Dry Density (MDD) of 1.504gm/cc at an OMC of 20.40%. The CBR value, Permeability and Unconfined Compressive Strength were found to be 3.80%, 1.29x10-4 cm/sec and 0.082kg/cm2 respectively. For the purpose of the improvement, various trials were conducted by mixing the collected specimen of Brahmaputra Silt with 5% Lime, 5% Bentonite and with 1.50%, 3.0%, 6.0% & 9.0% Lime in combination and with 2.0%, 5.0%, 7.0%, 10.0% and 12.0% Bentonite alone and tested for Liquid Limits, Plastic Limits, OMC-MDD value, CBR value, Permeability and Unconfined Compressive Strength. It was found that addition of Bentonite alone resulted in better improvement than with the addition of lime with or without Bentonite in composition. The results of the present study shall find utility in the adoption of Brahmaputra Silt for civil engineering construction such as roads, embankments etc. after suitable improvement to it.

description: When we place a colored filter in front of a camera the effective camera response functions are equal to the given camera spectral sensitivities multiplied by the filter spectral transmittance. In this paper, we solve for the filter which returns the modified sensitivities as close to being a linear transformation from the color matching functions of human visual system as possible. When this linearity condition - sometimes called the Luther condition - is approximately met, the `camera+filter' system can be used for accurate color measurement. Then, we reformulate our filter design optimisation for making the sensor responses as close to the CIEXYZ tristimulus values as possible given the knowledge of real measured surfaces and illuminants spectra data. This data-driven method in turn is extended to incorporate constraints on the filter (smoothness and bounded transmission). Also, because how the optimisation is initialised is shown to impact on the performance of the solved-for filters, a multi-initialisation optimisation is developed. Experiments demonstrate that, by taking pictures through our optimised color filters we can make cameras significantly more colorimetric.

description: For calculating low-energy properties of a dilute gas of atoms interacting via a Feshbach resonance, we develop an effective theory in which the parameters that enter are an atom-molecule coupling strength and the magnetic moment of the molecular resonance. We demonstrate that for resonances in the fermionic systems $^{6}$Li and $^{40}$K that are under experimental investigation, the coupling is so strong that many-body effects are appreciable even when the resonance lies at an energy large compared with the Fermi energy. We calculate a number of many-body effects, including the effective mass and the lifetime of atomic quasiparticles in the gas.

description: Pyrococcus furiosus DSM 3638 is a model organism for hyperthermophilic archaea with an optimal growth temperature near 100∘C. The genome was sequenced about 18 years ago. However, some publications suggest that in contrast to other Pyrococcus species, the genome of P. furiosus DSM 3638 is prone to genomic rearrangements. Therefore, we re-sequenced the genome using third generation sequencing techniques. The new de novo assembled genome is 1,889,914 bp in size and exhibits high sequence identity to the published sequence. However, two major deviations were detected: (1) The genome is 18,342 bp smaller than the NCBI reference genome due to a recently described deletion. (2) The region between PF0349 and PF0388 is inverted most likely due an assembly problem for the original sequence. In addition, numerous minor variations, ranging from single nucleotide exchanges, deletions or insertions were identified. The total number of insertion sequence (IS) elements is also reduced from 30 to 24 in the new sequence. Re-sequencing of a 2-year-old “lab culture” using Nanopore sequencing confirmed the overall stability of the P. furiosus DSM 3638 genome even under normal lab conditions without taking any special care. To improve genome annotation, the updated DNA sequence was combined with an RNA sequencing approach. Here, RNAs from eight different growth conditions were pooled to increase the number of detected transcripts. Furthermore, a differential RNA-Seq approach was employed for the identification of transcription start sites (TSSs). In total, 2515 TSSs were detected and classified into 834 primary (pTSS), 797 antisense (aTSS), 739 internal and 145 secondary TSSs. Our analysis of the upstream regions revealed a well conserved archaeal promoter structure. Interrogation of the distances between pTSSs and aTSSs revealed a significant number of antisense transcripts, which are a result of bidirectional transcription from the same TATA box. This mechanism of antisense transcript production could be further confirmed by in vitro transcription experiments. We assume that bidirectional transcription gives rise to non-functional antisense RNAs and that this is a widespread phenomenon in archaea due to the architecture of the TATA element and the symmetric structure of the TATA-binding protein.

description: There has been strong interest among higher education institution in implementing technology-enhanced peer assessment as a tool for enhancing students' learning. However, little is known on how to use the peer assessment system in pre-instructional activities. This study aims to explore how technology-enhanced peer assessment can be embedded into pre-instructional activities to enhance students' learning. Therefore, the present study was an explorative descriptive study that used the qualitative approach to attain the research aim. This study used a questionnaire, students' reflections, and interview in collecting student's perceptions toward the interventions. The results suggest that the technology-enhanced pre-instructional peer assessment helps students to prepare the new content acquisition and become a source of students' motivation in improving their learning performance for the following main body of the lesson. A set of practical suggestions is also proposed for designing and implementing technology-enhanced pre-instructional peer assessment.

description: This paper is basically a composite of presentations made by FAO at the World Food Summit in November 1996. Some reflections have been added that relate specifically to the Caribbean Region. The paper is divided into four sections: World Perspective on Agricultural Trade; Food Security, Sustainability and Trade Liberalization; Impacts of the Uruguay Round on Agricultural Trade; Agricultural Trade and Trade Liberalization in the Caribbean Region. In the first section - World Perspective on Agricultural Trade - major changes taking place in the international trade environment are outlined. Then, the globalization of markets and some conclusions of the Uruguay Round are mentioned. Finally, a brief overview of the last two decades of world agricultural trade is described. In the second section - Food Security, Sustainability and Trade Liberalization - definitions and concepts are presented and the relationships between these definitions and concepts are discussed. The third section - Impacts of the Uruguay Round on 1 Agricultural Trade Liberalization - has a discussion of the agreement on agriculture from the Uruguay Round and matters related to it. Two important issues are: (1) that only partial liberalization of agricultural trade will occur, and (2) that countries and regions will not share equally in the benefits from increased trade. Based on world-wide experiences, the impact of trade liberalization on Latin America and the Caribbean is presented in section four - Agricultural Trade and Trade Liberalization in the Caribbean Region. The focus is on the Caribbean experience during recent years. A detailed Bibliography used for the preparation of the document is presented at the end of the paper.
Conditional dynamics driving financial markets

description: We report empirical evidences on the existence of a conditional dynamics driving the evolution of financial assets which is found in several markets around the world and for different historical periods. In particular, we have analyzed the DJIA database from 1900 to 2002 as well as more than 50 companies trading in the LIFFE market of futures and 12 of the major European and American treasury bonds. In all of the above cases, we find a double dynamics driving the financial evolution depending on whether the previous price went up or down. We conjecture that this effect is universal and intrinsic to all markets and, thus, it could be included as a new stylized fact of the market.

description: We present a derivation of the Von Neumann entropy and mutual information of arbitrary two--mode Gaussian states, based on the explicit determination of the symplectic eigenvalues of a generic covariance matrix. The key role of the symplectic invariants in such a determination is pointed out. We show that the Von Neumann entropy depends on two symplectic invariants, while the purity (or the linear entropy) is determined by only one invariant, so that the two quantities provide two different hierarchies of mixed Gaussian states. A comparison between mutual information and entanglement of formation for symmetric states is considered, remarking the crucial role of the symplectic eigenvalues in qualifying and quantifying the correlations present in a generic state.

description: We present a combination of the recently developed double incremental expansion of potential energy surfaces with the well-established adaptive density-guided approach to grid construction. This unique methodology is based on the use of an incremental expansion for potential energy surfaces, known as n-mode expansion, an incremental many-body representation of the electronic energy, and an efficient vibrational density-guided approach to automated determination of grid dimensions and granularity. The reliability of the method is validated calculating potential energy surfaces and obtaining fundamental excitation energies for three moderate-size chain-like molecular systems. The results are compared to other approaches, which utilize static grid construction for supersystem and fragmentation calculation setups. The use of our methodology leads to considerable computational savings for potential energy surface construction and a major reduction in the number of required single point calculations can be achieved, while maintaining a high level of accuracy in the resulting potential energy surfaces. Additional investigations indicate that our method can be applied to covalently bound and strongly interacting molecular systems, even though these cases are known as being very unfavorable for fragmentation schemes. We therefore conclude that the presented methodology is a robust and flexible approach to potential energy surface construction, which introduces considerable computational savings without compromising the accuracy of vibrational spectra calculations.
title: Sense of place and festival in Northern Italy: Perspectives on place, time and community
Creators: name: Howell, Francesca Ciancimino
Publisher: name: The Open University

description: This thesis focuses on the concept of sense of place in relation to five calendrical, place-based festivals in two regions of northern Italy: Lombardy and Piedmont. Drawing from interdisciplinary critical thought, including archaeology, environmental philosophy, ritual studies and performance studies, among others, the thesis examines how place is honoured, experienced and embodied. The thesis reviews critical thought on the interanimation of place and society, demonstrating how the agency of place can emerge in ritualised community celebrations, such as feasting and festival. The fundamental argument put forth is that in heterotopic and polychronic space such as that offered by ritual and festival, a bridge can be created showing profound communication between humanity and place. The symbolic actions and traditions observed and studied here manifest local or regional identity, with specific gastronomic and agricultural customs that offer uncommon performances of place-based traditions in annual community gatherings. Politics, history, identity and foodways are examined through the lens of engagement with place as well as with community. Theories on the agency of place, on temporality and materiality figure centrally in the argument, which illustrates how bonds and communication between place and humanity exhibit a sometimes surprisingly profound relational epistemology in late modem Western society. The analysis springs from both heuristic and hermeneutic philosophies of methodology, which maintain a historical, philosophical and ecological perspective. Based upon an extensive examination of the critical literature and the thesis' ethnographic surveys, the Italian festival fieldwork is analysed through the use of an indexed 'Scale of Engagement'.

description: Ultracold mixtures of different atomic species have great promise for realizing novel many-body phenomena. In a binary mixture of femions with a large mass difference and repulsive interspecies interactions, a disordered Mott insulator phase can occur. This phase displays an incompressible total density, although the relative density remain compressible. We use strong-coupling and Monte Carlo calculations to show that this phase exists for a broad parameter region for ultracold gases confined in a harmonic trap on a three-dimensional optical lattice, for experimentally accessible values of the trap parameters.

description: We present a comparison of late-type galaxies (Sa and later) in intermediate redshift clusters and the field using ACS imaging of four cluster fields: CL0152-1357, CL1056-0337 (MS1054), CL1604+4304, and CL1604+4321. Concentration, asymmetry, and clumpiness parameters are calculated for each galaxy in blue (F606W or F625W) and red (F775W or F814W) filters. Galaxy half-light radii, disk scale lengths, color gradients, and overall color are compared. We find marginally significant differences in the asymmetry distributions of spiral and irregular galaxies in the X-ray luminous and X-ray faint clusters. The massive clusters contain fewer galaxies with large asymmetries. The physical sizes of the cluster and field populations are similar; no significant differences are found in half-light radii or disk scale lengths. The most significant difference is in rest-frame $U-B$ color. Late-type cluster galaxies are significantly redder, $\sim 0.3$ magnitudes at rest-frame $U-B$, than their field counterparts. Moreover, the intermediate-redshift cluster galaxies tend to have blue inward color gradients, in contrast to the field galaxies, but similar to late-type galaxies in low redshift clusters. These blue inward color gradients are likely to be the result of enhanced nuclear star formation rates relative to the outer disk. Based on the significant rest-frame color difference, we conclude that late-type cluster members at $z\sim0.9$ are not a pristine infalling field population; some difference in past and/or current star formation history is already present. This points to high redshift ``groups'', or filaments with densities similar to present-day groups, as the sites where the first major effects of environment are imprinted.

description: Ceria has proven to be an excellent ion-transport and ion-exchange material when used in polycrystalline form and with a high-concentration of aliovalent doped cations. Despite its widespread application, the impact of atomic-scale defects in this material are scarcely studied and poorly understood. In this article, using first-principles simulations, we provide a fundamental understanding of the atomic-structure, thermodynamic stability and electronic properties of undoped grain-boundaries (GBs) and alkaline-earth metal (AEM) doped GBs in ceria. Using density-functional theory simulations, with a GGA+U functional, we find the $Σ$3 (111)/[$\bar{1}$01] GB is thermodynamically more stable than the $Σ$3 (121)/[$\bar{1}$01] GB due to the larger atomic coherency in the $Σ$3 (111)/[$\bar{1}$01] GB plane. We dope the GBs with $\sim$20% [M]$_{GB}$ (M=Be, Mg, Ca, Sr, and Ba) and find that the GB energies have a parabolic dependence on the size of solutes, the interfacial strain and the packing density of the GB. We see a stabilization of the GBs upon Ca, Sr and Ba doping whereas Be and Mg render them thermodynamically unstable. The electronic density of states reveal that no defect states are present in or above the band gap of the AEM doped ceria, which is highly conducive to maintain low electronic mobility in this ionic conductor. The electronic properties, unlike the thermodynamic stability, exhibit complex inter-dependence on the structure and chemistry of the host and the solutes. This work makes advances in the atomic-scale understanding of aliovalent cation doped ceria GBs serving as an anchor to future studies that can focus on understanding and improving ionic-transport.

description: Eigenfunctions and eigenvalues of the free magnetic Schrödinger operator, describing a spinless particle confined to an infinite layer of fixed width, are discussed in detail. The eigenfunctions are realized as an orthonormal basis of a suitable Hilbert space. Four different classes of temporally stable coherent states associated to the operator are presented. The first two classes are derived as coherent states with one degree of freedom and the last two classes are derived with two degrees of freedom. The dynamical algebra of each class is found. Statistical quantities associated to each class of coherent states are calculated explicitely.
