description: There is still a possibility that the Uruguay Round of Multilateral Trade Negotiations will successfully be completed by early 1993. If there is consensus on a new GATT agreement on the basis of the current discussion document, the so-called Dunkel proposals, it will have several implications for South Africa's agricultural marketing system. This paper intends to summarise the development of negotiations in the Round and refers to the proposals for the liberalisation of world agricultural trade as detailed in the Dunkel paper. This paper shows that if these proposals were to be accepted and implemented it will amongst other things implicate that Article 87 of the Marketing Act should be abolished and that all quantitative import controls on agricultural products should be replaced by tariffs. This will have the effect that the Marketing Boards will lose their statutory powers on imported agricultural products. Apart from the effects on South African agriculture, the whole of Southern Africa would benefit from a successful completion of the Round as a failure will put the whole sub-continent in competition with strong trade-blocs in a situation where there is no organisation like the GATT guarding against unfair trading practices.
Quark Mass Textures and sin 2 beta

description: Recent precise measurements of sin 2 beta from the B-factories (BABAR and BELLE) and a better known strange quark mass from lattice QCD make precision tests of predictive texture models possible. The models tested include those hierarchical N-zero textures classified by Ramond, Roberts and Ross, as well as any other hierarchical matrix Ansatz with non-zero 12 = 21 and vanishing 11 and 13 elements. We calculate the maximally allowed value for sin 2 beta in these models and show that all the aforementioned models with vanishing 11 and 13 elements are ruled out at the 3 sigma level. While at present sin 2 beta and |Vub/Vcb| are equally good for testing N-zero texture models, in the near future the former will surpass the latter in constraining power.

description: The Laboria Minute of September 1990 resulted in an agreement that legislation on labour relations cannot work unless there has been extensive consultation with at least the major parties in the labour relations arena. Interest groups involved in the agricultural labour relations framework are identified using the tools of public choice theory. Resulting legislation reflects the relative political weight of these interest groups within the existing institutional structure. A change in this structure will result in a different weighting of the various groups along with new legislation reflecting the most politically powerful interests. An update on what has transpired in the agricultural labour relations arena is given along with policy implications and conclusions.

description: We introduce a method to rotate arbitrarily the excitation profile of universal broadband composite pulse sequences for robust high-fidelity population inversion. These pulses compensate deviations in any experimental parameter (e.g. pulse amplitude, pulse duration, detuning from resonance, Stark shifts, unwanted frequency chirp, etc.) and are applicable with any pulse shape. The rotation allows to achieve higher order robustness to any combination of pulse area and detuning errors at no additional cost. The latter can be particularly useful, e.g., when detuning errors are due to Stark shifts that are correlated with the power of the applied field. We demonstrate the efficiency and universality of these composite pulses by experimental implementation for rephasing of atomic coherences in a $\text{Pr}^{3+}\text{:}\text{Y}_2\text{SiO}_5\:$ crystal.

description: The classical Lorenz lowest order system of three nonlinear ordinary differential equations, capable of producing chaotic solutions, has been generalized by various authors in two main directions: (i) for number of equations larger than three (Curry1978) and (ii) for the case of complex variables and parameters. Problems of laser physics and geophysical fluid dynamics (baroclinic instability, geodynamic theory, etc. - see the references) can be related to this second aspect of generalization. In this paper we study the asymptotic properties of some complex Lorenz systems, keeping in the mind the physical basis of the model mathematical equations.

description: We present the results of an interferometric study of 38 millimeter-wave lines of CH3OH in the region around the water maser source W3(H2O) and a region extending about 30" to the south and west of the hydroxyl maser source W3(OH). The methanol emitting region around W3(H2O) has an extent of 2.0" x 1.2" (4400 x 2600 AU). The density is of order 1.e7 cm-3, sufficient to thermalize most of the methanol lines. The kinetic temperature is approximately 140 K and the methanol fractional abundance greater than 1.e-6, indicative of a high degree of grain mantle evaporation. The W3(H2O) source contains sub-structure, with peaks corresponding to the TW source and Wyrowski's B/C, separated by 2500 AU in projection. The kinematics are consistent with these being distinct protostellar cores in a wide binary orbit and a dynamical mass for the region of a few tens of Mo. The extended methanol emission to the southwest of W3(OH) is seen strongly only from the lowest excitation lines and from lines known elsewhere to be class I methanol masers, namely the 84.5 GHz 5(-1)-4(0)E and 95.2 GHz 8(0)-7(1)A+ lines. Within this region there are two compact clumps, which we denote as swA and swB, each about 15" (0.16 pc projected distance) away from W3(OH). Excitation analysis of these clumps indicates the presence of lines with inverted populations but only weak amplification. The sources swA and swB appear to have kinetic temperatures of order 50-100 K and densities of order 1.e5 - 1.e6 cm-3. The methanol fractional abundance for the warmer clump is of order 1.e-7, suggestive of partial grain mantle evaporation. The clumping occurs on mass scales of order 1 Mo.

description: Angular distribution of the final particles in the decay $Λ_c^+\to K^- \, Δ(1232)^{++} \to K^- \, p \, π^+$ of the polarized charmed baryon is discussed. Asymmetries are proposed which allow for determination of the components of the $Λ_c^+$ polarization vector. The precession angle of the polarization in the process of baryon channeling in a bent crystal is directly related to these asymmetries. The decay rate and asymmetry parameter for the $Λ_c^+\to K^- \, Δ(1232)^{++}$ decay are calculated in the pole model and compared with experiment.

description: Increased consumption of poultry products in Nigeria is occurring alongside rapid urbanization and growth in the industry. We use a panel data double-hurdle model to consistently identify key factors affecting engagement in the Nigerian subsector by various actors. Our analysis reveals that there is active engagement in the Nigerian poultry sub sector by a much broader set of actors than traditionally perceived. There is also a huge data gap in appropriate field survey data on the poultry value chain in Nigeria.

Experimentally measured trapped field values for the first sample coincide remarkably well with calculated ones in the whole temperature range. This proves, from one side, the validity of the introduced calculation approach, and demonstrates, from another side, the great prospects of the hot pressing technology for large scale superconducting applications of the MgB2.

description: We critically study the possibility of quantum Zeno effect for indirect measurements. If the detector is prepared to detect the emitted signal from the core system, and the detector does not reflect the signal back to the core system, then we can prove the decay probability of the system is not changed by the continuous measurement of the signal and the quantum Zeno effect never takes place. This argument also applies to the quantum Zeno effect for accelerated two-level systems, unstable particle decay, etc.

description: Occupational and environmental exposures to pesticides cause a wide range of human health problems. This study assessed the health effect of pesticide use in Egbeda Local Government Area of Oyo State with from socioeconomic point of view by identifying the various pesticides used, describing the health signs and symptoms associated with pesticide application and determining the health effects of pesticide application on farm households. The survey instrument was a well-structured questionnaire administered to respondents through multiple stage sampling technique. A total of 120 respondents were interviewed for the study. Data collected were analysed using descriptive statistics and Tobit regression model. The results showed that commonly used pesticides comprised of herbicides (61.67 %), fungicides (20.0%) and insecticides (18.33%). Majority (95%) reported that they or someone in their family had suffered from pesticide-related health signs and symptoms during or after application of pesticides. The effect of pesticides application on farmer’s health’s was captured by exposure, frequency of exposure and pesticide cocktails. The coefficient of exposure, frequency of exposure and pesticide cocktails were positive and significant at p<0.01, p<0.1and p<0.05 respectively. It is therefore recommended that the awareness of farmers and authorities needs to be raised regarding the use of protective equipment and correct procedures when handling pesticides and, also, that there should be stricter enforcement of existing pesticide regulation and monitoring policies to minimize the threats that farmers’ current practices pose to their health and the livelihood sustainability.

description: We have discovered the existence of extremely polydisperse High Internal-Phase-Ratio Emulsions (HIPE) in which the internal-phase droplets, present at 95% volume fraction, remain spherical and organize themselves in the available space according to Apollonian packing rules. Such Apollonian emulsions are obtained from dispersing oil dropwise in water in the presence of very little surfactant, and allowing them to evolve at rest for a week. The packing structure of the droplets was confirmed through size distribution measurements that evolved spontaneously towards power laws with the known Apollonian exponents, as well as comparison of the structure factors of aged HIPEs measured by Small-Angle X-ray Scattering with that of a numerically simulated Random Apollonian Packing. Thanks to the perfect sphericity of the droplets, Apollonian emulsions were found to display Newtonian ow even at such extremely high volume fraction. We argue that these fascinating space-filling assemblies of spherical droplets are a result of coalescence and fragmentation processes obeying simple geometrical rules of conserving total volume and sphericity, minimizing the elastic energy associated with interactions of neighbouring droplets.

description: We investigate the synchronization phenomenon in coupled chaotic map lattices where the couplings decay with distance following a power-law. Depending on the lattice size, the coupling strength and the range of the interactions, complete chaos synchronization may be attained. The synchronization domain in parameter space can be analytically delimited by means of the condition of negativity of the largest transversal Lyapunov exponent. Here we analyze in detail the role of all the system parameters in the ability of the lattice to achieve complete synchronization, testing analytical results with the outcomes of numerical experiments.

 Schizotricha southgeorgiae Peña Cantero and Vervoort 2004a, 32–35, Figure 2.
 Material examined. ? 000AG, one distal stem fragment ca 21 mm long (USNM 1025595); 22/1536, five stem fragments (largest ca 380 mm long); possibly belonging to two stems (holotype, USNM 1012905; paratype, RMNH-Coel. 30918).
 Diagnosis. Colonies with unbranched stems. Main cauline tube with single hydrothecate internodes with two to five infrathecal nematothecae. Hydrocladia up to fourth order. Hydrocladia heteromerously divided into internodes; with ahydrothecate internode, provided with one nematotheca, following cauline and hydrocladial apophyses. Unforked hydrocladial internodes with one infrathecal nematotheca. Hydrotheca deep. Forked hydrocladial internodes with two infrathecal nematothecae.
 Remarks. The material of this species was previously described and figured by Peña Cantero and Vervoort (2004a). The identity of material from Sta. 000AG is slightly doubtful since it differs from S. southgeorgiae in a few characters. Primarily, the occasional presence of one suprathecal nematotheca in the cauline internodes, usually when the following internode is shorter and provided with only two infrathecal nematothecae. Secondly, hydrocladia were unbranched, but note that this material consists of a single distal stem fragment. Thirdly, two infrathecal nematothecae occurred at different levels in the first hydrocladial internodes. Those internodes could be considered homologous to the first forked internodes of S. southgeorgiae that have two infrathecal nematothecae. In the remaining hydrocladial internodes with two infrathecal nematothecae, with a single exception, there is always an indication of reconstruction.
 Ecology and distribution. Schizotricha southgeorgiae is known only from off South Georgia, where it was collected between 659 and 686 m depth in February (Peña Cantero and Vervoort 2004a).

description: We present an extension of the modular recursive Green's function method (MRGM) for ballistic quantum transport to include magnetic fields. Dividing the non-separable two-dimensional scattering problem into separable substructures allows us to calculate transport coefficients and scattering wavefunctions very efficiently. Previously unattainable energy and magnetic field regions can thereby be covered with high accuracy. The method is applied to magnetotransport through a circle and a stadium shaped quantum dot at strong magnetic fields and high energies. In the edge state regime we observe strong multi-frequency Aharonov-Bohm oscillations. By analyzing them in terms of a multi-channel interference model, we classify these fluctuations within the framework of Fano resonances and discuss their geometry independence. For high energies (mode numbers) we observe localization of the scattering wavefunction near classical trajectories.

description: The relativistic density functional with minimal density dependent nucleon-meson couplings for nuclei and nuclear matter is extended to include tensor couplings of the nucleons to the vector mesons. The dependence of the minimal couplings on either vector or scalar densities is explored. New parametrisations are obtained by a fit to nuclear observables with uncertainties that are determined self-consistently. The corresponding nuclear matter parameters at saturation are determined including their uncertainties. An improvement in the description of nuclear observables, in particular for binding energies and diffraction radii, is found when tensor couplings are considered, accompanied by an increase of the Dirac effective mass. The equations of state for symmetric nuclear matter and pure neutron matter are studied for all models. The density dependence of the nuclear symmetry energy, the Dirac effective masses and scalar densities is explored. Problems at high densities for parametrisations using a scalar density dependence of the couplings are identified due to the rearrangement contributions in the scalar self-energies that lead to vanishing Dirac effective masses.

description: We present a canonical approach to study properties of QCD at finite baryon density rho, and apply it to the determination of the phase diagram of four-flavour QCD. For a pion mass of about 350 MeV, the first-order transition between the hadronic and the plasma phase gives rise to a co-existence region in the T-rho plane, which we study in detail. We obtain accurate results for systems containing up to 30 baryons and quark chemical potentials mu up to 2T. Our T-mu phase diagram agrees with the literature when mu/T < 1. At larger chemical potential, we observe a ``bending down'' of the phase boundary. We characterise the two phases with simple models: the hadron resonance gas in the hadronic phase, the free massless quark gas in the plasma phase.

description: The Green-Schwarz action for a non-BPS p=2 brane embedded in a N=1, D=4 target superspace is shown to be equivalent to the Nambu-Goto-Akulov-Volkov action obtained via the nonlinear realization of the associated target space super-Poincare symmetries. Introducing a U(1) gauge field strength as a Lagrange multiplier, this p=2 brane action is re-cast into its equivalent dual form non-BPS D2-brane Born-Infeld action. Following the procedure given by Sen, the Green-Schwarz action for a non-BPS D2-brane is determined directly. From it, conversely, the dual form non-BPS p=2 brane action is derived. The p=2 brane and the D2-brane actions obtained by these two approaches are different in form. Through explicitly determined field redefinitions, these actions are shown to be equivalent.

description: We explore entanglement loss along renormalization group trajectories as a basic quantum information property underlying their irreversibility. This analysis is carried out for the quantum Ising chain as a transverse magnetic field is changed. We consider the ground-state entanglement between a large block of spins and the rest of the chain. Entanglement loss is seen to follow from a rigid reordering, satisfying the majorization relation, of the eigenvalues of the reduced density matrix for the spin block. More generally, our results indicate that it may be possible to prove the irreversibility along RG trajectories from the properties of the vacuum only, without need to study the whole hamiltonian.

description: Due to rapid urbanization, population growth, rising living standards as well as changing lifestyle and diets, food waste has emerged as a crucial issue with far reaching implications on food security and environmental sustainability in developing countries, including Nigeria. Consequently, this study examined socioeconomic factors influencing household food waste in Abeokuta, Nigeria. Data were collected using multi-stage sampling procedure, and analysed using descriptive statistics and Tobit regression. The average value of food waste was N1, 499.67 per month with cereals accounting for the largest percentage (27.97%) of total value of food waste. Food waste is mostly experienced during storage and as left-over across various food groups. The results of the Tobit regression model showed that gender and age of household, location of households (rural dummy), household income, type of work of household head, presence of children, presence of refrigerator and unawareness of the environmental effects of waste had varying significant influences on household food waste of different food groups in the study area. The study recommends that government should improve the level of infrastructure development (electricity), in order to encourage households to utilize refrigerators and other electricity dependent storage equipment, which can help reduce the amount of food waste. In addition, public enlightenment about the moral and environmental effects of food waste should be pursued vigorously.

description: A strong trend for quantum based technologies and applications follows the avenue of combining different platforms to exploit their complementary technological and functional advantages. Micro and nano-mechanical devices are particularly suitable for hybrid integration due to the easiness of fabrication at multi-scales and their pervasive coupling with electrons and photons. Here, we report on a nanomechanical technological platform where a silicon chip is combined with an aluminum nitride layer. Exploiting the AlN piezoelectricity, Surface Acoustic Waves are injected in the Si layer where the material has been localy patterned and etched to form a suspended nanostring. Characterizing the nanostring vertical displacement induced by the SAW, we found an external excitation peak efficiency in excess of 500 pm/V at 1 GHz mechanical frequency. Exploiting the long term expertise in silicon photonic and electronic devices as well as the SAW robustness and versatility, our technological platform represents a strong candidate for hybrid quantum systems.

Thermal conductivity of doped $\rm\bf La_2CuO_4$ as an example for heat transport by optical phonons in complex materials

description: We investigate the phonon thermal conductivity $κ_{\mathrm{ph}}$ of doped $\rm La_2CuO_4$ based on out-of-plane thermal conductivity measurements. When room temperature is approached the temperature dependence of $κ_{\mathrm{ph}}$ strongly deviates from the $T^{-1}$-decrease which is usually expected for heat transport by acoustic phonons. Instead, $κ_{\mathrm{ph}}$ decreases much weaker or even increases with rising temperature. Simple arguments suggest that such unusual temperature dependencies of $κ_{\mathrm{ph}}$ are caused by heat transport via dispersive optical phonons.

description: In molecular dynamics simulations under periodic boundary conditions, particle positions are typically wrapped into a reference box. For diffusion coefficient calculations using the Einstein relation, the particle positions need to be unwrapped. Here, we show that a widely used heuristic unwrapping scheme is not suitable for long simulations at constant pressure. Improper accounting for box-volume fluctuations creates, at long times, unphysical trajectories and, in turn, grossly exaggerated diffusion coefficients. We propose an alternative unwrapping scheme that resolves this issue. At each time step, we add the minimal displacement vector according to periodic boundary conditions for the instantaneous box geometry. Here and in a companion paper [J. Chem. Phys. XXX, YYYYY (2020)], we apply the new unwrapping scheme to extensive molecular dynamics and Brownian dynamics simulation data. We provide practitioners with a formula to assess if and by how much earlier results might have been affected by the widely used heuristic unwrapping scheme.

description: I start by reviewing existing $\vec{p}p$ measurements with particular emphasis on the recent 221 MeV $\vec{p}p$ measurement at TRIUMF which permitted the weak meson-nucleon coupling constants $h^{pp}_ρ$ and $h^{pp}_ω$ to be determined separately for the first time. I then review $\vec{n}p$ experiments, with specific details of the $\vec{n}p \to dγ$ experiment now under preparation at Los Alamos National Laboratory. This experiment will provide a clean measurement of the weak pion nucleon coupling, $f_π$. Finally, I discuss $\vec{e}p$ parity violation experiments, particularly the Gzero experiment under way at Jefferson Lab in Virginia. This experiment will measure the weak form factors $G_E^z$ and $G_M^z$, allowing the distribution of strange quarks in the quark sea to be determined.

The influence of mental health and campus climate on the academic engagement, academic disengagement, and academic success of queer-spectrum college students
Creators: name: Greathouse, Maren
Publisher: name: No Publisher Supplied
Year: 2021

description: The mental health of queer-spectrum college students, and the campus climate they traverse, exert significant influence on the academic engagement, disengagement, and success for this population. Two-thirds of queer-spectrum college students reported a mental health condition, and these students had a more unfavorable perception of the campus climate for diversity than their mentally healthy queer spectrum peers. Mental health—mediated through campus climate—had a negative relationship to collaborative learning, but students were no less academically involved in the classroom. Mental health—mediated through campus climate—also had a negative relationship to extracurricular engagement and grade point average, and a positive relationship with poor academic habits. This study includes directions for future research and recommendations for practice, including auditing institutions to assess equity in the living and learning environment, targeted queer-spectrum support services, risk reduction and psychoeducational programming, anti-bias/ally training, peer mentoring opportunities, access to—and quality of care—with physical and mental health service providers, off-campus support, and academic support.
Shareholder Voting Power and Ownership Control of Companies

description: The pattern of ownership and control of British industry is unusual compared with most other countries in that ownership is relatively dispersed. Typically the largest shareholder in any large listed company is likely to own a voting minority of the shares. Majority ownership by a single shareholder is unusual. It is not uncommon for the largest shareholding to be under 20 percent and in many cases it is much less than that. A broadly similar pattern is observed in the USA. Two inferences about corporate governance are conventionally drawn from this, following the early work of Berle and Means: (1) All but the very largest shareholders are typically too small to have any real incentive to participate in decision making; (2) All but the very largest shareholdings are too small to have any real voting power. The question of voting power is the focus of this paper. Conventional analyses use a rule of thumb of 20%, assuming shareholders to be fundamentally passive in relation to the running of the company, whatever their style of investment management, unless one of them is above this figure. The London Stock Exchange defines a controlling holding to be one greater than 30 percent. Much empirical work uses declarable stakes, which in the UK are those of 3 percent or more, and disregards anything smaller assuming it to be powerless. In fact, however, a 1% stake in the 100th largest company (Smiths Industries) is worth about £29million, which suggests its owner has strong incentives to be active, and might wish to use his voting power. Theoretical voting power of minority shareholding blocks is studied using the gametheoretic idea of voting power indices. This is applied to a model of ownership control based on the definition of control used by Berle and Means in their classic study. The results give support for use of a 20 percent rule in many cases but not all. Also they support the idea that many companies are potentially controlled by a block of a few large shareholders working in concert.
