Operations management impact on achieving strategic fit: A case from the retail sector in Zimbabwe

Abstract For a long time, Zimbabwe’s retail industry has been operating in a very “hostile business environment”, due to the country’s economic instability and uncertainty associated with it. The adoption of the green back has attracted foreign investors mainly from Nigeria, South Africa and China who have since opened their retail outlets in the country and fuelled more competition in the sector which resulted in some local operators closing their businesses but XYZ Zimbabwe has survived. This study makes an assessment of achievements and obstacles in using operations management to achieve strategic fit by the selected case study. The main objectives of the study are; to explore competitive strategies, examine supply chain strategies and provide solution-based strategies that helped the case study achieve strategic fit. Through an empirical approach, the study finds that XYZ Zimbabwe differentiated itself in the market by branding, positioning its stores conveniently to customers, offering variety of products at low prices to the customers and the company’s supply chain management hinges on the demand and supply integration to gain competitive advantage.
Consumers of human services: powerless or poorly informed?

Consumer choice in social care may worsen quality at the low end of the quality scale. Many social care recipients are not consumer sovereign; they depend on others to safeguard their interests, but their representation may be weak. U.S. and Norwegian data on nursing home patients‘ complaint behaviour and family network substantiate this claim. A Schelling diagram shows how residents‘ dependency – when only some individuals have representatives who search for good homes and monitor care – increases (decreases) the proportion of residents with committed representatives monitoring care in high (low) quality homes. Though choice is important as an individual right, public supervision is necessary to protect vulnerable consumers.
Mittag-Leffler modules, reduced products, and direct products

SUMMARY - In this paper we prove that every Mittag-Leffler module is a pure submodule of a reduced product of pure-projective modules. This leads us to look for characterizations of the rings over which all reduced products of Mittag-Leffler modules are Mittag-Leffler modules. Here we focus our at-tention on the rings over which every direct product of Mittag-Leffler modules is a Mittag-Leffler module.
You Can Do Better than “Sell in May” It Is not Halloween, but It May Be Passover and Hanukah

Sell in May, known also as the Halloween effect, continues to persist in many parts of the world and to puzzle researchers and practitioners. Prior research found that in a few certain countries this effect is not statistically significant or does not exist. This paper shows that although Halloween effect is not significant in Israel, it can be easily replaced by another profitable calendar strategy, holding the market index just for the months of April and December each year and investing the money in the risk-free asset for the rest of the year. This strategy may not persist in the future, however it is puzzling how it prevailed over 20 years since the inception of a prime Tel Aviv market index. We show that the superior performance of this strategy compared to its natural benchmarks is robust using risk-adjusted measures over multiple sub-periods in our sample.
Noding in Cyprideis torosa and its causes

The ostracod Cyprideis torosa develops nodes on its calcified carapace in brackish waters and is therefore widely used in paleontology as a marker for lower saline waters. The formation of nodes in lower saline waters was investigated with SEM and TEM analyses and micro-cryoscopic measurements of the inner osmoregulation. Noding is considered a failure in osmoregulation, which causes the pillars connecting the inner and outer epidermal cell layer to rupture during the molting process. As a result, the still flexible shell develops protrusions, which then persist as nodes after subsequent calcification.
Interactive comment on “Multiresolution analysis of the spatiotemporal variability in global radiation observed by a dense network of 99 pyranometers during the HOPE campaign” by Bomidi

The time series of global radiation observed by a dense network of 99 autonomous pyranometers during the HOPE campaign around Jülich, Germany are investigated with a multiresolution analysis based on the maximum overlap discrete wavelet transform and the Haar wavelet. For different sky conditions, typical wavelet power spectra are calculated to quantify the timescale dependence of variability in global transmittance. [. 2 ]Distinctly higher variability is observed at all frequencies in the power spectra of global transmittance under broken cloud conditions compared to clear, cirrus or overcast skies. The 5 spatial autocorrelation function including its frequency-dependence is determined to quantify the degree of similarity of two time series measurements as a function of their spatial separation. Distances ranging from 100 m to 10 km are considered, and a rapid decrease of the autocorrelation function is found with increasing frequency and distance. For frequencies [. 3 ]above 1/3 min−1 and points separated by more than 1 km, variations in transmittance become completely uncorrelated[. 4 ]. A method is introduced to estimate the deviation between a point measurement and a spatially averaged value for a surrounding 10 domain, which takes into account domain size and averaging period, and is used to explore the representativeness of a single pyranometer observation for its surrounding region. Two distinct mechanisms are identified, which limit the representativeness: on the one hand, spatial averaging reduces variability and thus modifies the shape of the power spectrum. On the other hand, the correlation of variations of the spatially averaged field and a point measurement decreases rapidly with increasing temporal frequency. For a grid-box of 10×10 km and averaging periods of 1.5–3 h, the deviation of global transmittance between a point 15 measurement and an area-averaged value depends on the prevailing sky conditions: 2.8% (clear), 1.8% (cirrus), 1.5% (overcast) and 4.2% (broken clouds). The solar global radiation observed at a single station is found to deviate from the spatial average by as much as 14–23 W m−2 (clear), 8–26 W m−2 (cirrus), 4–23 W m−2 (overcast), and 31–79 W m−2 (broken clouds) from domain averages ranging from 1×1 km to 10×10 km in area.
On Attributes and Templates for Identification of Nuclear Weapons in Arms Control

Two approaches have been proposed for arms-control transparency measurements: attributes and template comparisons. Characteristics distinguishing the two approaches are, first, that in an attribute approach measured characteristics of only a single item are evaluated whereas in a template approach measurements of items are compared with data for reference item(s). Second, the template approach necessarily requires storage of the reference data. The same measured data (radiation spectra, mass, etc.) could be used in both approaches. In applications involving nuclear weapons or related materials, both approaches require a trusted information barrier to prevent unintended transfer of sensitive information while simultaneously assuring reliable verification. Parties to an attribute-based agreement must specify the quantitative value and acceptable deviation, or range of values, for each attribute to be evaluated. Because of the diversity and sensitivity of design information, the list of attributes selected for comparison tends to be restricted, and ranges of acceptable values might have to be so wide that real weapons could not be uniquely distinguished from non-weapon configurations of nuclear material. In a template approach the precise quantitative values are contained in the template and, with a reliable information barrier, remain unknown to the inspecting party. Measured characteristics can be compared far more precisely in the template mode than would be acceptable if the parties must negotiate and agree on allowable values and ranges. If the authenticity of the template can be assured, the template approach may provide higher-confidence verification through comparison of sensitive characteristics with sufficient precision to detect, and thereby deter, deception. Attribute and template procedures could be combined in the same inspection. Analogous to the two-level attributes/variables measurement approach used by the IAEA in safeguards inspections, some items would be evaluated quickly and simply for gross consistency of measured characteristics with agreed values. Additionally, incorporation of potentially more precise comparisons with templates, measured under conditions that support their authenticity, would allow for anomaly resolution and provide further assurance and deterrence against
Does depositing money in bank impact economic growth? Evidence from Nigeria

The aim of this study is to examine the role of banks deposit money in the growth of Nigerian economy. The study was based on time series; data for the study were sourced from the Federal Bureau of Statistics, CBN statistical bulletin which covered 1974 to 2010. The co-integration and error correction model and structural analysis were used, both ADF and PP was adopted in testing for the unit root. At the end of our analysis, we discovered that there exist a long-run relationship between the dependent and the explanatory variables. The results conform to the economic a priori expectation. Thus, policies that tend to increase the gross domestic product through the financial sector such as increase in banks deposit liability, low interest rate, high liquidity ratio were recommended for better economy.

A DUAL BAND MIMO DIELECTRIC RESONATOR ANTENNA FOR WLAN APPLICATION

In this paper, a dual band multiple-input-multiple-output dielectric resonator antenna for wireless local area network application is presented. Two identical feeding techniques are used to feed the proposed antenna. The simulated impedance bandwidth for both port are the same which are 6.5% at 2.45 GHz and 3% at 5.2 GHz. The DRA also has an acceptable value of isolation over the operating frequency. The simulated S-parameter and other multiple-input-multiple-output parameters are studied and observed.
The Role of e-laboratories in Science Education

Laboratory-based courses play a critical role in science education, yet there is disagreement between science and engineering educators about whether and which types of technology-mediated laboratories should be involved to promote better conceptual understanding, better design skills and better professional skills of learners. In this study, we focused on the evaluation of the efficiency of different types of e-labs, using Ma and Nickerson (2006) four-dimensional educational goal models. We found different patterns and enlarged the model to five dimensions. We tried to specify clearly the differences, advantages and disadvantages of all three kinds of elabs according to educational goals to be achieved. We also tried to investigate which aspects of the laboratory experience are most essential to learners and if those lab characteristics have a relationship to learner characteristics or to prior experience. In the second part of the study, we focused on investigating (not verifying) the hypothesis, that it is not the actual nature of the laboratories, but the beliefs that students and teachers have about them which may determine the effectiveness of different lab types.

Manipulating Rab GTPase activity in wheat to improve gluten quality for breadmaking

In the developing endosperm of bread wheat (Triticum aestivum), seed storage proteins are produced on the rough endoplasmic reticulum (ER) and transported to protein bodies, specialised vacuoles for the storage of protein. The important gluten proteins of wheat are transported to the protein bodies they are stored in by two distinct routes. One route consists of vesicles that bud directly off the ER, while the other involves transport through the Golgi (Arcalis et al, 2004). In plants, the RabD clade mediates ER to Golgi vesicle transport (Batoko et al, 2000). Available sequence information for Rab GTPases in Arabidopsis, rice, Brachypodium and bread wheat was compiled and compared in phenetic trees. Partial genetic sequences were assembled using the first draft of the Chinese Spring wheat genome. A suitable candidate gene from the RabD clade (TaRabD2a) was chosen for down-regulation by RNA interference (RNAi) and an RNAi construct was used to transform wheat plants. Using real time PCR, all four available RabD genes were shown to be knocked down in the developing endosperm of transgenic wheat. The transgenic grain was found to produce flour with significantly altered processing properties when measured by farinograph and extensograph. SE-HPLC found that a smaller proportion of HMW-GS and large LMW-GS are incorporated into the glutenin macropolymer in the transgenic dough. Lower protein content but a similar protein profile on SDS-PAGE was seen in the transgenic grain
SPHERICITY: MESH OPTIMIZATION FOR ARBITRARY ELEMENT TOPOLOGY

In this paper, a new method for optimizing CFD meshes, based on the usage of a geometric quantity called Sphericity, is introduced. Sphericity is an element-wise property that provides a measure of the shapes deviation from a perfect sphere. When used as an objective in a gradient based framework, it results in a fast, scale invariant, optimization algorithm ap-plicable to arbitrary ﬁnite volume element topologies. The methodology is heuristic in nature in that it does not consider known numerical quality metrics explicitly. Our study has however shown it to be exceptionally robust and effective in improving mesh quality, provided that grid topology does not introduce fundamentally concave cells. The main focus of this paper is the development of a robust optimization algorithm that can effectively handle complications arising from constraints imposed by surface interactions. Specif-ically, efﬁcient heuristic and gradient based techniques, for handling difﬁcult mesh topologies with acutely curved surfaces, feature edges and high aspect ratio layer cells are introduced. In combination with the base method, these measures ensure exceptional quality meshes even on industrial scale applications. As a ﬁnal step, the method is integrated into a general purpose mesh motion framework, allowing
Nonlinear lossy light bullets in self-focusing media with nonlinear absorption

We review the properties of nonlinear, multidimensional localized waves whose stationary propagation is sustained by a dynamic equilibrium between self-focusing and nonlinear losses. Their finite-energy versions preserve light bullet behavior well-beyond the characteristic diffraction or dispersion distances, and rebuild after obstacles. There exists a preferential lossy light bullet with maximum intensity and losses, defined solely by the optical properties of the medium, which is the most stable, non-conical localized wave supported by a medium with self-focusing nonlinearity and nonlinear losses. This preferential lossy light bullet acts as an attractor during self-focusing of Gaussian-like wave packets when collapse is halted by nonlinear absorption, a fact that can explain relevant characteristics of the observed light filament dynamics in media with anomalous dispersion.
Development and Statistical optimization of mucoadhesive drug delivery system of famotidine using Hibiscus esculentus polysaccharide

The presentstudy was aimed to formulate and evaluate oral mucoadhesive drug deliverysystem of purified Hibiscus esculentusL polysaccharide (HEP) using famotidine as model drug. A centralcomposite design for 2 factors at 3 levels each was employed to evaluate theeffect of critical variables i.e. concentration of HEP and PVP K30 on drugrelease and mucoadhesive properties of the formulated tablets. FT-IRspectroscopy and Differential Scanning Calorimetry was carried out to evaluatedrug polymer interaction. Formulated tablets were evaluated for physicalproperties, drug release characteristic and physical stability. Ex-vivo mucoadhesion study using goatgastric mucosa was carried out to ascertain the mucoadhesion potential offormulated tablets.The responsesurface analysis clearly indicated the dominating effect of HEP on mucoadhesivestrength, mucoadhesion time and dissolution half life, while PVP K30 has anadditive effect on all afore mentioned responses. The drug release from thematrix tablets was highly affected by the concentration of release retardantspolysaccharide. The kinetics of drug release was found to be first order in lowconcentration but with increase in polymer concentration the release patternshifted towards zero order and is governed by both Higuchi and Hixson-Crowelequation indicating a coupling effect of diffusion and erosion. The result ofthe study suggests that, HEP can be optimistically explored as excellentmucoadhesive agent with controlled release characteristics.
Radial velocities for the HIPPARCOS-Gaia Hundred-Thousand-Proper-Motion project

(abridged) The Hundred-Thousand-Proper-Motion (HTPM) project will determine the proper motions of ~113500 stars using a 23-year baseline. The proper motions will use the Hipparcos data, with epoch 1991.25, as first epoch and the first intermediate-release Gaia astrometry, with epoch ~2014.5, as second epoch. The expected HTPM proper-motion standard errors are 30-190 muas/yr, depending on stellar magnitude. Depending on the characteristics of an object, in particular its distance and velocity, its radial velocity can have a significant impact on the determination of its proper motion. The impact of this perspective acceleration is largest for fast-moving, nearby stars. Our goal is to determine, for each star in the Hipparcos catalogue, the radial-velocity standard error that is required to guarantee a negligible contribution of perspective acceleration to the HTPM proper-motion precision. We employ two evaluation criteria, both based on Monte-Carlo simulations, with which we determine which stars need to be spectroscopically (re-)measured. Both criteria take the Hipparcos measurement errors into account. For each star in the Hipparcos catalogue, we determine the confidence level with which the available radial velocity and its standard error, taken from the XHIP compilation catalogue, are acceptable. We find that for 97 stars, the radial velocities available in the literature are insufficiently precise for a 68.27% confidence level. We also identify 109 stars for which radial velocities are currently unknown yet need to be acquired to meet the 68.27% confidence level. To satisfy the radial-velocity requirements coming from our study will be a daunting task consuming a significant amount of spectroscopic telescope time. Fortunately, the follow-up spectroscopy is not time-critical since the HTPM proper motions can be corrected a posteriori once (improved) radial velocities become available.
Electric Signals on and under the Ground Surface Induced by Seismic Waves

We constructed three observation sites in northeastern Japan (Honjo, Kyowa, and Sennan) with condenser-type large plate electrodes (4 × 4 m2) as sensors supported 4 m above the ground and with pairs of reference electrodes buried vertically at 0.5 m and 2.5 m depth (with a ground velocity sensor at Sennan only). Electrical signals of an earthquake (M6.3) in northeastern Japan were detected simultaneously with seismic waves. Their waveforms were damped oscillations, with greatly differing signal amplitudes among sites. Good positive correlation was found between the amplitudes of signals detected by all electrodes. We propose a signal generation model: seismic acceleration vertically shook pore water in the topsoil, generating the vertical streaming potential between the upper unsaturated water zone and the lower saturated water zone. Maximum electric earth potential difference was observed when one electrode was in the saturated water zone, and the other was within the unsaturated water zone, but not when the electrodes were in the saturated water zone. The streaming potential formed a charge on the ground surface, generating a vertical atmospheric electric field. The large plate electrode detected electric signals related to electric potential differences between the electrode and the ground surface.
