Nurturing a culture and climate of resilence to navigate the whitewaters of the South African dual economy

South African business institutions function within what may best be described as a dual manufacturing and services economy, inherently integrated within a larger global economy that is characterised as highly competitive and subject to unexpected discontinuous change. Karl Weick and Kathleen Sutcliffe (2001:2), in research how institutions deal with unexpected trends and events, suggest that in general managers are not at all that adept in this regard and consequently events spiral, get worse and disrupt the operations of the institution. The researchers go on to claim that commitment to resilience and an ability to bounce back from ''those inevitable errors that are part of an indeterminate world'', are critical facets in managing an enterprise (Weick & Sutcliffe 2001:2). Yet it is claimed by McManus, Seville, Brunsdon and Vargo (2007) that there is little consensus regarding how institutions might achieve greater resilience in the face of increasing contextual instability. Hui and Sit (2005:180) suggest that a primary function of culture is ''to serve as an appraisal heuristic, enabling individuals to efficiently assess objects, events and people in their environment''. It is therefore implied that culture and climate play a role in the institutional response to unexpected emergent contextual conditions that impact on an institution and consequently its resilience capability. In this paper institutional resilience is therefore explored, with reference to organisational culture and climate as behavioural determinants and the influence thereof in dealing with the complexity of a South African dual manufacturing and services economy.
Radiative natural supersymmetry: Reconciling electroweak fine-tuning and the Higgs boson mass

Models of natural supersymmetry seek to solve the little hierarchy problem by positing a spectrum of light higgsinos m_0 leads to automatic cancellations during renormalization group (RG) running, and to radiatively-induced low fine-tuning at the electroweak scale. Coupled with large mixing in the top squark sector, RNS allows for fine-tuning at the 3-10% level with TeV-scale top squarks and a 125 GeV light Higgs scalar h. The model allows for at least a partial solution to the SUSY flavor, CP and gravitino problems since first/second generation scalars (and the gravitino) may exist in the 10-30 TeV regime. We outline some possible signatures for RNS at the LHC and at a linear e^+e^- collider. If the strong CP problem is solved by the Peccei-Quinn mechanism, then RNS naturally accommodates mixed axion-higgsino cold dark matter, where the light higgsino-like WIMPS - which in this case make up only a fraction of the measured relic abundance - should be detectable at upcoming WIMP detectors.
The New Numerical Galaxy Catalogue (ν2GC): properties of active galactic nuclei and their host galaxies

We present the latest results of a semi-analytic model of galaxy formation, "New Numerical Galaxy Catalogue", which is combined with large cosmological N-body simulations. This model can reproduce statistical properties of galaxies at z < 6.0. We focus on the properties of active galactic nuclei (AGNs) and supermassive black holes, especially on the accretion timescale onto black holes. We find that the number density of AGNs at z < 1.5 and at hard X-ray luminosity 10^{ 44 }< erg/s is underestimated compared with recent observational estimates when we assume the exponentially decreasing accretion rate and the accretion timescale which is proportional to the dynamical time of the host halo or the bulge, as is often assumed in semi-analytic models. We show that to solve this discrepancy, the accretion timescale of such less luminous AGNs instead should be a function of the black hole mass and the accreted gas mass. This timescale can be obtained from a phenomenological modelling of the gas angular momentum loss in the circumnuclear torus and/or the accretion disc. Such models predict a longer accretion timescale for less luminous AGNs at z < 1.0 than bright QSOs whose accretion timescale would be 10^{ 7-8 } yr. With this newly introduced accretion timescale, our model can explain the observed luminosity functions of AGNs at z < 6.0.
Sr-ISOTOPE RATIOS OF A SOIL PROFILE (BADLANDS) NEAR RADICOFANI (SOUTHERN TUSCANY)

The Sr/Ca ratios and Sr-isotope ratios of bulk samples and acetate extracts from a soil profile developed on Pliocene marine clays near Radicofani, in southern Tuscany, were determined. The uniform Sr/Ca ratios in the soil indicated a uniform distribution of the two elements throughout the profile. In contrast, the lower Sr/Ca ratios of acetate extracts from the upper horizons of the soil suggest preferential removal of Sr relative to Ca, perhaps by the plants. These latter seem to accumulate more Sr than Ca during their lifetime. The δ 87 Sr of acetate extracts suggests that bulk Sr is provided by the calcite of the Mesozoic-Cenozoic sedimentary formations of southern Tuscany. A minor source of Sr, although subordinate, is represented by clastic albite. A grass sample growing on the soil contained the Sr uptaken from both sources.
Use of simulation models to plan species reintroductions: the case of the bearded vulture in southern Spain

I used VORTEX to make a prior evaluation of the planned reintroduction project of the endangered bearded vulture (Gypaetus barbatus) in the mountains of southern Spain. The minimum size of a captive population needed to ensure the release of two bearded vulture fledglings per year is 30 individuals. If breeding success was improved, this minimum captive population could be reduced to 10 individuals. As the cost of the project is proportional to the size of the captive population, some research effort should be devoted to improving breeding success in captivity. The current size of the captive population — four individuals — is not enough to start the releases, even if the vultures were already breeding. The first step for the project should be to increase the size of the captive population. If on average one individual per year was added to the captive population, it would take 15 years to reach 30 individuals. If breeding in captivity was improved, it would take only three to seven years to reach the minimum captive population of 10 individuals. Once releases were started, the project would need on average 20 years to reach a goal of 15 adult pairs in the Cazorla mountains. Both the success of the project and the time necessary to reach this stated goal are very sensitive to the mortality rates in the wild. There is little known about these rates, and better estimates are urgently needed to improve the predictions of the models.
TBX 5 loss-of-function mutation contributes to atrial fibrillation and atypical Holt-Oram syndrome

Previous genome‐wide association studies have demonstrated that single nucleotide polymorphisms in T‐box (TBX)5 are associated with increased susceptibility to atrial fibrillation (AF), and a recent study has causally linked a TBX5 mutation to atypical Holt‐Oram syndrome and parox‐ ysmal AF. However, the prevalence and spectrum of TBX5 mutations in patients with AF remain to be elucidated. In the present study, a cohort of 190 unrelated patients with idio‐ pathic AF were prospectively recruited, with 400 unrelated healthy individuals recruited as controls. The coding exons and flanking introns of the TBX5 gene were sequenced in the participants. The functional characteristics of the mutant TBX5 were delineated in contrast with its wild‐type counter‐ part using a dual‐luciferase reporter assay system. As a result, a novel heterozygous TBX5 mutation, p.P132S, was identified in an index patient with AF, with a mutational prevalence of ~0.53%. Genetic analysis of the proband's family showed that the mutation co‐segregated with AF, and was transmitted in an autosomal dominant pattern. The missense mutation was absent in the 800 control chromosomes, and the altered amino acid was completely evolutionarily conserved across species. Functional analyses revealed that the mutant TBX5 had significantly reduced transcriptional activity. Furthermore, the mutation markedly decreased the synergistic activation between TBX5 and NK2 homeobox 5, another transcription factor which has been causatively linked to AF. The present study was the first, to the best of our knowledge, to report on the association between a TBX5 loss‐of‐function mutation and increased susceptibility to AF. These results provide novel insight into the molecular mechanism underpinning AF, and have potential implications in the development of novel prophylactic and therapeutic strategies for AF, the most common form of sustained cardiac arrhythmia.
The Related Factors Influencing on Self-rated Health Level of Middle-aged Women

This survey of 836 midlife women (51.0 ± 4.0 yrs) was undertaken by exclusively a face to face interview by welltrained interviewers guarantying data collection of higher quality. This survey data was analyzed using the SPSS program. The main purpose of this study was to describe the factors affecting self-rated health status, including dietary habits and physical·mental·social factors. In the self-rated health status of a ‘good’ group, age was lower (p < 0.05), monthly income was higher (p < 0.01), dietary habits score (p < 0.001) and appetite (p < 0.001) and the degree of movement (p < 0.001) and life satisfaction (p < 0.001), marital intimacy (p < 0.001) and relationship satisfaction with their children (p < 0.001) were significantly higher than the ‘bad’ group. The level of depression (p < 0.001) and severe feeling of menopausal symptoms (p < 0.001) were significantly higher in the ‘poor’ group. The results of correlation analysis demonstrated that educational level (r = 0.069, p < 0.05),income (r = 0.157, p < 0.001), eating habits (r = 0.235, p < 0.001), appetite (r = 0.263, p < 0.001), life satisfaction (r = 0.197, p < 0.001), marital intimacy (r = 0.167, p < 0.001), child relationship satisfaction (r = 0.149, p < 0.001), positive attitude toward menopause (r = 0.070, p < 0.05) showed a positive correlation, but depression (r = -0.122, p < 0.001) and menopausal symptoms (r = -0.292, p < 0.001) showed a negative association with self-rated health status. The predictable factors affecting the self-rated health status of middle-aged women were examined by multiple regression analysis. The ‘menopausal symptoms - physical discomfort’ was the most important variables followed by the ‘appetite’, ‘eating habits’, ‘menopause symptoms - sensory problems’, ‘BMI’, ‘positive attitude toward menopause’ and ‘high marital intimacy’. These results showed that the ‘appetite’ and ‘eating habits’ are important factors affecting the self-rated health status. Therefore, a program of dietary education must be considered for the effective health education and counseling of middle-aged women. (Korean J Community Nutr 17(3) : 290~301, 2012)
Not “ monkey ” Not “ prairie dog ” Not “ meerkat ” ComplementaryLabel True Label Meerkat MonkeyPrairie Dog

In this paper, we study the classi cation problem in which we have access to easily obtainable surrogate for true labels, namely complementary labels, which specify classes that observations do not belong to. Let Y and Ȳ be the true and complementary labels, respectively. We rst model the annotation of complementary labels via transition probabilities P (Ȳ = i|Y = j), i 6= j ∈ {1, · · · , c}, where c is the number of classes. Previous methods implicitly assume that P (Ȳ = i|Y = j), ∀i 6= j, are identical, which is not true in practice because humans are biased toward their own experience. For example, as shown in Figure 1, if an annotator is more familiar with monkeys than prairie dogs when providing complementary labels for meerkats, she is more likely to employ “monkey” as a complementary label. We therefore reason that the transition probabilities will be di erent. In this paper, we propose a framework that contributes three main innovations to learning with biased complementary labels: (1) It estimates transition probabilities with no bias. (2) It provides a general method to modify traditional loss functions and extends standard deep neural network classi ers to learn with biased complementary labels. (3) It theoretically ensures that the classi er learned with complementary labels converges to the optimal one learned with true labels. Comprehensive experiments on several benchmark datasets validate the superiority of our method to current state-of-the-art methods. ∗UBTECH Sydney AI Centre and the School of Information Technologies in the Faculty Engineering and Information Technologies at The University of Sydney, NSW, 2006, Australia, xiyu0300@uni.sydney.edu.au, tongliang.liu@sydney.edu.au, dacheng.tao@sydney.edu.au †Department of Biomedical Informatics, University of Pittsburgh,gongmingnju@gmail.com ‡Department of Philosophy, Carnegie Mellon University 1 ar X iv :1 71 1. 09 53 5v 3 [ st at .

Methyl chloride as a tracer of tropical tropospheric air in the lowermost stratosphere inferred from IAGOS‐CARIBIC passenger aircraft measurements

We present variations of methyl chloride (CH3Cl) and nitrous oxide (N2O) in the lowermost stratosphere (LMS) obtained from air samples collected by the In‐service Aircraft for a Global Observing System‐Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container (IAGOS‐CARIBIC) passenger aircraft observatory for the period 2008–2012. To correct for the temporal increase of atmospheric N2O, the CARIBIC N2O data are expressed as deviations from the long‐term trend at the northern hemispheric baseline station Mauna Loa, Hawaii (ΔN2O). ΔN2O undergoes a pronounced seasonal variation in the LMS with a minimum in spring. The amplitude increases going deeper in the LMS (up to potential temperature of 40 K above the thermal tropopause), as a result of the seasonally varying subsidence of air from the stratospheric overworld. Seasonal variation of CH3Cl above the tropopause is similar in phase to that of ΔN2O. Significant correlations are found between CH3Cl and ΔN2O in the LMS from winter to early summer, both being affected by mixing between stratospheric air and upper tropospheric air. This correlation, however, disappears in late summer to autumn. The slope of the CH3Cl‐ΔN2O correlation observed in the LMS allows us to determine the stratospheric lifetime of CH3Cl to be 35 ± 7 years. Finally, we examine the partitioning of stratospheric air and tropical/extratropical tropospheric air in the LMS based on a mass balance approach using ΔN2O and CH3Cl. This analysis clearly indicates efficient inflow of tropical tropospheric air into the LMS in summer and demonstrates the usefulness of CH3Cl as a tracer of tropical tropospheric air.
Surprise and humor in product design: Designing sensory metaphors in multiple modalities

When information from two or more sensory modalities conflicts, this can evoke a surprise reaction as well as feelings of amusement, interest, confusion or disappointment. In concurrence to joke theory, we argue that people appreciate and enjoy appropriate incongruities that can be related back to the product, whereas they are confused by and have negative opinions towards inappropriate incongruities. This paper reports the design and the evaluation of products in two categories (rubber duckies and deodorants), with (in)appropriate sensory incongruities of three types: visual-tactual, visual-olfactory and visual-auditory. Participants evaluated the level of surprise felt and the intensity of resulting emotions. They also indicated their overall liking for the products. Both appropriate and inappropriate incongruities were evaluated as surprising as well as confusing. As expected, appropriate incongruities evoked more amusement and were generally favored. Whereas products with visualtactual incongruities showed large differences in ratings on liking and amusement between appropriate and inappropriate incongruities, these differences were smaller for products with visual-auditory and visual-olfactory incongruities. Possibly, the appropriateness of an incongruity is more conspicuous when it is brought about by a conflict between touch and vision than when olfaction or audition are involved.
The Relationship between Network Security Policies and Audit Evidence Documentation: The Accounting Information Security Culture as a Mediator

The purpose of this study is to explore the relationship between network security policies (the department policy, system director policy, user policy, information security officer policy) on the one hand, and audit evidence documenting on the other hand. As the security, culture of accounting information has been introduced as a variable mediating that relationship. The researcher sent (450) questionnaires to all the companies listed on the Amman Stock Exchange in Jordan equivalent to (228) company until 2015. The study found that there is a significant relationship between networks (the department policy, system director policy, user policy, information security officer policy) and documentation of the audit evidence. While the respondents said that, there is not a significant relationship between information security officer and policy and documentation of the audit evidence. Besides, the value of the correlation coefficient between network security policies and documentation of audit evidence had increased from (0.56) to (0.62), after entering the variable of security culture of accounting information systems to demonstrate its impact as a variable rate of the regression model and this result demonstrates the importance of awareness of security culture of the companies. These results will be very useful for those are interested, especially auditors to help them to appreciate the importance of documenting the audit evidence of network security and their implementation on the ground.
School dropout in graduate distance education : evidence from a study in the interior of Brazil 1 *

The rapid development and dissemination of information technologies in the last decades has allowed a great expansion in the offer of undergraduate and graduate distance programs. However, this dissemination has been accompanied by high dropout rates, consistently reported in different programs and countries. This is the reality of distance education in Brazil too: a great expansion, including the establishment of Universidade Aberta do Brasil (UAB Open University of Brazil), but with high failure rates. This study evaluated school dropout and its causes in a graduate certificate program of Programa Nacional de Formação em Administração Pública (PNAP National Training Program in Public Administration), which aims to train public administrators in the interior of Brazil. High failure rates in these programs have been an obstacle to achieving the objectives of PNAP, because they prevent the training of labor precisely where it is most needed. This article investigates the main factors that lead to this phenomenon, by means of documentary analysis and collection of data on students from Universidade Federal da Grande Dourados, in Mato Grosso do Sul state, Brazil, via survey. After the collection, conducted through questionnaires and interviews, we did a statistical analysis of the data, which revealed a graduate student profile consistent with that reported in the literature and conducive to school dropout. It is verified that, given this student profile, some administrative strategies are necessary to prevent dropout rates from being so high. Such strategies are notoriously not enough to reduce dropout rates to acceptable levels; on the other hand, not developing strategies ensures dropout rates will not decrease.
The 1561 Earthquake(s) in Southern Italy: New Insights into a Complex Seismic Sequence

In the summer of 1561, a strong seismic sequence struck southern Italy, then the Spanish-ruled Kingdom of Naples. Both the Italian seismological tradition and the latest catalogues locate it in the Vallo di Diano (Diano Valley), a low-seismicity intermontane basin 100 km south-east of Naples. We explore the hypothesis that current perception of the 1561 earthquake is distorted by the nature of the historical dataset from which its parameters have been assessed, and which mostly derive from a single—albeit very detailed—primary source. We present and discuss several previously unconsidered original accounts. Our results cast doubts on the traditional interpretation of the earthquake, which could have been either one Vallo di Diano mainshock or several strong earthquakes within a time/space window compact enough for contemporary viewers to perceive them as one. Unquestionably, there is much more to the 1561 earthquake(s) than previously appeared. We hope that this groundbreaking effort will rekindle the interest of the seismological community in this seismic episode, our knowledge of which is still far from complete.
QUALITY ASSESSMENT OF YOGHURT PRODUCED AT LARGE (INDUSTRIAL) AND SMALL SCALE

The quality of fermented dairy products is a delicate subject. In addition to processing conditions, it largely depends on pre and post process handling. The present study is concerned with the physicochemical and microbiological quality of comme rcially available yogurt in Faisalabad, Pakistan. For this purpose, two branded (produced at large scale) and three unbranded(produced at small scale) yoghurt samples were collected from the city and were analyzed in triplicate . The data was analyzed by c omplete randomized design (1 -factor factorial) and comparison of means was done by Duncans multiple range test. The coliform count in branded samples was nil or ignorable. However, unbranded samples contained a highercountof coliforms. The branded sampl es were monocultured ( S. thermophilus ), which does not fulfill the quality criteria as L. bulgaricusis also needed for good quality yoghurt. In contrast, in unbranded samples,both the bacteria were present but their growth was uncontrolled . The fat, lact ose and total solid contents were low in unbranded yoghurt samples than in branded samples showing lack of standardization . However, acidity and syneresis value of branded samples were low as compared to unbranded samples.
New Trends for the Processing of Poly(Methyl Methacrylate) Biomaterial for Dental Prosthodontics

Rehabilitation of masticatory function in patients with absent teeth with removable dentures is an established form of treating partial or complete dentition in edentulous patients. The developments in recent decades with dental implants dominate current dental research. However, medical contraindications, a negative attitude toward implants, or financial limitations on the part of the patients limit their universal applicability, so the rehabilitation with dental prostheses still makes up a significant portion of everyday clinical practice. Conversely, removable dentures are used in the critical conditions of the oral cavity. There are about 500 strains of microorganisms in the mouth, which form the biofilm in an acidic environment causing several issues, such as denture stomatitis, deterioration of the periodontal status of the remaining teeth, or carious lesions in the supporting teeth. Therefore, it is very important to choose a suitable material for the prosthesis. Poly(methyl methacrylate) (PMMA) is an acrylic resin usually used with a long tradition for prosthetic purposes. The aim of this chapter is to present the trends for the processing of PMMA. It includes the chemical synthesis, conventional thermal processing of this acrylic resin, the new processing technique assisted with ultrasound, the antibacterial effect on PMMA with nanoparticles, and the cytotoxicity, genotoxicity, and mutagenesis of this material.
