Perceived challenges to talent management in the South African public service :an exploratory study of the City of Cape Town municipality

Local government municipalities in South Africa are faced with a serious challenge of service delivery. Research continues to point to a plethora of problems in the public service that lead to the failure of municipalities in the country to deliver services to the local population. One of the problems emanating from research is poor talent management strategies that fail to retain key talent in the public service. The aim of the study was to explore perceived challenges to talent management at the City of Cape Town municipality. A qualitative research method was adopted for the study with the semi-structured interview utilised as the data collection tool and conducted on twenty senior managers at the municipality. Data collected was subjected to the content analysis method. Challenges facing talent management at the City of Cape Town municipality included failure to retain key talent, lack of employee recognition, succession planning and management problems, and sluggish career management strategies. These talent management challenges were found to be connected to the dependent variables of the study like pay satisfaction, turnover and intention to turnover theories, organisational commitment, employee engagement and motivation. To overcome these challenges, it was recommended that the City of Cape Town municipality must devise a strategy that will ensure that highly talented employees are retained for the longest time within the employ of the organisation. This, inter alia, included the recommendation that senior managers must ensure that they recognise the individual input and efforts of those they lead. Key words: Talent management, motivation, organisational commitment, employee engagement, pay satisfaction, job satisfaction, turnover, intention to turnover.
Why Students Drop Out of School and What Can Be Done

Because dropping out is influenced by both individual and institutional factors, intervention strategies can focus on either or both sets of factors. That is, intervention strategies can focus on addressing the individual values, attitudes, and behaviors that are associated with dropping out without attempting to alter the characteristics of families, schools, and communities that may contribute to those individual factors. Many dropout prevention programs pursue such programmatic strategies by providing would-be dropouts with additional resources and supports to help them stay in school.
The role of language skills in corporate communication

The international firms' management of subsidiaries abroad necessarily implies the question of how to manage language problems. Even if this is obvious, only a few researchers have dealt with the problem of language skills in corporate communications as this paper will show. This paper will furthermore discuss how Danish firms with subsidiaries in France solve their language problems. The paper points out different kinds of solutions to the language problems and shows the consequences of these solutions. Typically the firms have no language strategy, which results in a muddling‐through the day‐to‐day problems of how to communicate.
Managing An Organizational Learning System By Aligning Stocks and Flows

This paper considers the relationship between the stocks and flows of learning across levels in an overall organizational learning system. A survey instrument based on the Strategic Learning Assessment Map (SLAM) was administered to 15 individuals representing senior-, middle- and non-management levels from each of 32 organizations, resulting in a total sample of 480 respondents. This research supports the premise that there is a positive relationship between the stocks of learning at all levels and business performance. Furthermore, the proposition that the misalignment of stocks and flows in an overall organizational learning system is negatively associated with business performance is also supported.
Effect of B-Cell Depletion on Viral Replication and Clinical Outcome of Simian Immunodeficiency Virus Infection in a Natural Host

ABSTRACT Simian immunodeficiency virus (SIV)-infected African nonhuman primates do not progress to AIDS in spite of high and persistent viral loads (VLs). Some authors consider the high viral replication observed in chronic natural SIV infections to be due to lower anti-SIV antibody titers than those in rhesus macaques, suggesting a role of antibodies in controlling viral replication. We therefore investigated the impact of antibody responses on the outcome of acute and chronic SIVagm replication in African green monkeys (AGMs). Nine AGMs were infected with SIVagm.sab. Four AGMs were infused with 50 mg/kg of body weight anti-CD20 (rituximab; a gift from Genentech) every 21 days, starting from day −7 postinfection up to 184 days. The remaining AGMs were used as controls and received SIVagm only. Rituximab-treated AGMs were successfully depleted of CD20 cells in peripheral blood, lymph nodes (LNs), and intestine, as shown by the dynamics of CD20+ and CD79a+ cells. There was no significant difference in VLs between CD20-depleted AGMs and control monkeys: peak VLs ranged from 107 to 108 copies/ml; set-point values were 104 to 105 SIV RNA copies/ml. Levels of acute mucosal CD4+ T-cell depletion were similar for treated and nontreated animals. SIVagm seroconversion was delayed for the CD20-depleted AGMs compared to results for the controls. There was a significant difference in both the timing and magnitude of neutralizing antibody responses for CD20-depleted AGMs compared to results for controls. CD20 depletion significantly altered the histological structure of the germinal centers in the LNs and Peyer's patches. Our results, although obtained with a limited number of animals, suggest that humoral immune responses play only a minor role in the control of SIV viral replication during acute and chronic SIV infection in natural hosts.
Islamic Banking And Economic Growth: A Review

Many previous studies have focused on the impact of finance on economic growth. However, few studies have examined the impact of Islamic banking on economic growth. To fill this gap in literature, this paper investigates the potential effects of Islamic banking on economic growth. The paper has two main results. The first result is that previous studies show mixed support for the hypothesis that Islamic banking is a main channel of economic growth. The second result is that previous studies on the impact of Islamic banking on growth are single-country studies and their findings are difficult to generalize. In addition, the results of this paper point to several implications for policy. One of its implications for policy is that Islamic banking positively contributes to countrys macroeconomic stability.
Efficiency and the Bear: Short Sales and Markets around the World

We analyze cross-sectional and time series information from forty-seven equity markets around the world, to consider whether short-sales restrictions affect the efficiency of the market, and the distributional characteristics of returns to individual stocks and market indices. Using the approach developed in Morck et.al. (2000) we find significantly more cross-sectional variation in equity returns in markets where short selling is feasible and practiced, controlling for a host of other factors. This evidence is consistent with more efficient price discovery at the individual security level. A common conjecture by regulators is that short-selling restrictions can reduce the relative severity of a market panic. We test this conjecture by examining the skewness of market returns. We find that in markets where short selling is either prohibited or not practiced, returns display significantly less negative skewness, and the frequency of extreme negative returns is lower. On the other hand, the overall volatility of individual returns and market returns is higher.
East Asia's growth: technology or accumulation?

Krugman, building on the work of Alwyn Young, has argued that hypergrowth in East Asia derives mostly from factor accumulation, owing little to technological change. Yet this explanation is at odds with what analysts of technological change have to say about technology acquisition in these countries. This article examines the Young-Krugman thesis and argues that the problem lies in the misconception of technological change as distinct from accumulation. The critique is taken further by means of a review of the multifaceted way that technology raises the productivity of labor. It is argued that technology is carried not as disembodied knowledge, but as techniques hard-coded in physical devices and structures, by patterns soft-coded in human and organizational capabilities and business-friendly institutions, formal and informal. These operate as symbiotic complements, not separable substitutes as assumed in conventional theory. These arguments are supplemented by perspectives introduced from the technology literature. Since the respective roles and relationship between accumulation and technology are scrutinized, the analysis provides important policy conclusions on the value of East Asian growth strategies.

Slow Change at the Top: 'Old Hands' and 'Accidental Executives' in New South Wales Local Government

Scholars and practitioners alike have recognised that an increased role for women leaders in Australian local government would strengthen the sector, yet little research to date has examined the career paths of non-elected officials. This article combines the gender in organisations literature with career theory to examine the career paths of 16 general managers (GMs) in New South Wales. We found that half the participants had linear career paths based entirely within local government and half had boundaryless careers originating outside the sector. This second cohort consisted overwhelmingly of women. Nevertheless, a high incidence of happenstance characterised both career types. Several participants saw themselves pitted against a gendered (i.e. male) group of ‘old hands’ who were resistant to change being driven by ‘accidental executives’, a high proportion of whom were women. The findings have implications for a sector attempting to attract and retain skilled staff, particularly women.
Asexual but Not Clonal: Evolutionary Processes in Automictic Populations

Many parthenogenetically reproducing animals produce offspring not clonally but through different mechanisms collectively referred to as automixis. Here, meiosis proceeds normally but is followed by a fusion of meiotic products that restores diploidy. This mechanism typically leads to a reduction in heterozygosity among the offspring compared to the mother. Following a derivation of the rate at which heterozygosity is lost at one and two loci, depending on the number of crossovers between loci and centromere, a number of models are developed to gain a better understanding of basic evolutionary processes in automictic populations. Analytical results are obtained for the expected neutral genetic variation, effective population size, mutation–selection balance, selection with overdominance, the spread of beneficial mutations, and selection on crossover rates. These results are complemented by numerical investigations elucidating how associative overdominance (two off-phase deleterious mutations at linked loci behaving like an overdominant locus) can in some cases maintain heterozygosity for prolonged times, and how clonal interference affects adaptation in automictic populations. These results suggest that although automictic populations are expected to suffer from the lack of gene shuffling with other individuals, they are nevertheless, in some respects, superior to both clonal and outbreeding sexual populations in the way they respond to beneficial and deleterious mutations. Implications for related genetic systems such as intratetrad mating, clonal reproduction, selfing, as well as different forms of mixed sexual and automictic reproduction are discussed.
The Disappearance of Race in Mortgage Lending*

Abstract In the past 25 years, housing researchers, governmental regulators, industry advocates, and community activists have all relied on a unified analytical infrastructure that was developed in the 1970s to monitor racial and geographic inequalities in U.S. housing markets. Since the mid-1990s, however, several developments in the housing finance sector have undermined a key element of this system: data collected under the auspices of the Home Mortgage Disclosure Act of 1975. The second-largest racial-ethnic group among mortgage loan applicants is now officially designated as “information not provided. ” In this article, we analyze the causes and geography of this disappearance and its consequences for civil rights enforcement, academic research on redlining and discrimination, and community activism. Our analysis is simultaneously a cautionary narrative of the steady erosion of a valuable public data system and a strategic intervention intended to salvage the empirical contributions of the data for interdisciplinary research, community right-to-know purposes, and public policy development. Using Atlanta, Georgia, as a case study, we marshal a suite of multivariate techniques to disentangle the geographic, individual, and institutional factors responsible for the rise in unreported applications. We also devise a simple method to estimate the “true” racial and ethnic composition of the pool of unknown applicants. The contributions of this endeavor are mediated by the political and epistemological problems of racialization and categorical reification.
Translating Local Knowledge at Organizational Peripheries

This article theorizes about the kinds of knowing present in organizations that share both a structural similarity in the organization of work and work practices - a 'double periphery' in which a community of practitioners acts across both a horizontal, geographic periphery and a vertical, hierarchical periphery - and a common mode of practice - translating across these peripheral borders. In principle, these workers develop knowledge in interaction with clients and customers that could be valuable to the organization, were it but to learn from them. Instead, the 'local knowledge' they learn in acting across these peripheries is discounted, if not disparaged, by more centrally-located managers and executives. The article theorizes about the nature of translating local knowledge concerning organizational practices and about the structural character of local versus 'expert' knowledge.
PTEN Overexpression Cooperates With Lithium to Reduce the Malignancy and to Increase Cell Death by Apoptosis via PI3K/Akt Suppression in Colorectal Cancer Cells

Lithium is a well‐established non‐competitive inhibitor of glycogen synthase kinase‐3β (GSK‐3β), a kinase that is involved in several cellular processes related to cancer progression. GSK‐3β is regulated upstream by PI3K/Akt, which is negatively modulated by PTEN. The role that lithium plays in cancer is controversial because lithium can activate or inhibit survival signaling pathways depending on the cell type. In this study, we analyzed the mechanisms by which lithium can modulate events related to colorectal cancer (CRC) progression and evaluated the role that survival signaling pathways such as PI3K/Akt and PTEN play in this context. We show that the administration of lithium decreased the proliferative potential of CRC cells in a GSK‐3β‐independent manner but induced the accumulation of cells in G2/M phase. Furthermore, high doses of lithium increased apoptosis, which was accompanied by decreased proteins levels of Akt and PTEN. Then, cells that were induced to overexpress PTEN were treated with lithium; we observed that low doses of lithium strongly increased apoptosis. Additionally, PTEN overexpression reduced proliferation, but this effect was minor compared with that in cells treated with lithium alone. Furthermore, we demonstrated that PTEN overexpression and lithium treatment separately reduced cell migration, colony formation, and invasion, and these effects were enhanced when lithium treatment and PTEN overexpression were combined. In conclusion, our findings indicate that PTEN overexpression and lithium treatment cooperate to reduce the malignancy of CRC cells and highlight lithium and PTEN as potential candidates for studies to identify new therapeutic approaches for CRC treatment.

In Vitro Comparison of Four Aminoglycoside Antibiotics: Sisomicin, Gentamicin, Tobramycin, and BB-K8

The activity of sisomicin, gentamicin, and tobramycin against 273 clinical bacterial isolates was about equal (except for greater activity of tobramycin against Pseudomonas) and was greater than that of BB-K 8 as determined by antibiotic dilution methods in agar and broth.
Goodwill Accounting and Performance Measurement

Purpose - The purpose of this paper is to outline the link between value creation, performance measurement and goodwill accounting according to the International Financial Reporting Standards (IFRS) and United States Generally Accepted Accounting Principles (US-GAAP). Since economic goodwill is identical to the present value of future residual income, the paper examines how accounting information gathered for impairment testing of goodwill according to International Accounting Standard (IAS) 36 and Financial Accounting Standard (FAS) 142 can be used for internal control purposes. Design/methodology/approach - The paper adopts common assumptions in the literature of residual income-based valuation and analytically derives a periodic performance measure of both value creation and its realization based on information available from impairment testing. Findings - This paper demonstrates that information required by IFRS and US-GAAP to evaluate a firm's goodwill can be used to design a performance measurement system which provides information about both value creation and realization of value. Practical implications - From a practical perspective, the paper shows that appropriate adjustments of data used in impairment testing result in information which ideally fits the requirements of an optimal performance measurement system. Originality/value - The paper presents a performance measure which provides information about the actual creation of value as well as its realization in a period and is superior to traditional residual income-based performance measures.
Souvenirs and Tourism Styles

Tourism souvenirs hold strong symbolic value related to pleasurable travel experiences in people's lives. Using principal component analysis and ANOVA techniques, profiles of tourists were developed based on their souvenir buying and tourism styles. Four distinct and integrated patterns of behavior emerged related to tourists' preferences for travel activities, souvenir products, and shopping. Results provide support for hypotheses that souvenir buying and tourism styles are associated.
The nature of the research-induced supply shift

Differences among firms in a competitive industry can affect the shape of the industry supply curve. It is necessary to know how both production costs and rents are affected by research. Industry response to research will be different depending upon whether entry occurs. If the effect of entry is ignored, then the price decline from research will be overstated. Industry marginal returns can be positive with purely yield‐increasing research, even when industry demand is inelastic. Standard formulas for calculating producer surplus based on linear industry supply and demand curves are strictly valid only if the analysis is restricted to short‐run equilibrium behaviour.
RBST USE AMONG U.S. DAIRY FARMERS: A COMPARATIVE ANALYSIS FROM 6 STATES

This paper uses data from dairy farmers in six U.S. states to examine farm-level factors influencing the adoption of recombinant bovine somatatropin (rBST), a productivity-enhancing hormone that is injected in cows. The results of multinomial logit estimations of rBST adoption and disadoption show that herd size, education, and complementary technologies all play positive and important roles in rBST adoption.
Are the Australian and New Zealand stock prices nonlinear with a unit root

Whether or not stock prices are characterized by a unit root has important implications for policy. For instance, by applying unit root tests one can deduce whether stock returns can be predicted from previous changes in prices. A finding of a unit root implies that stock returns cannot be predicted. This paper investigates whether or not stock prices for Australia and New Zealand can be characterized by a unit root process. An unrestricted two-regime threshold autoregressive model is used with an autoregressive unit root. Among the main results, it is found that the stock prices of both countries are nonlinear processes that are characterized by a unit root process, consistent with the efficient market hypothesis.
Prognosis Identi fi cation of Serum Proton NMR Metabolomic Fingerprints Associated with Hepatocellular Carcinoma in Patients with Alcoholic Cirrhosis

Purpose:Metabolomics depicts metabolic changes in biologic systems using a multiparametric analysis technique. This study assessed the metabolomic profiles of serum, obtained by proton nuclear magnetic resonance (NMR) spectroscopy, from cirrhotic patients with andwithout hepatocellular carcinoma (HCC). Experimental Design: The study included 154 consecutive patients with compensated biopsy-proven alcoholic cirrhosis. Among these, 93 had cirrhosis without HCC, 28 had biopsy-proven HCC within the Milan criteria and were eligible for curative treatment (small HCC), and 33 had HCC outside the Milan criteria (large HCC). Proton spectra were acquired at 500 MHz. An orthogonal partial latent structure [orthogonal projection to latent structure (OPLS)] analysis model was built to discriminate large HCC spectra from cirrhotic spectra. Small HCC spectra were secondarily projected using previously built OPLS discriminant components. Results: The OPLS model showed discrimination between cirrhotic and large HCC spectra. Metabolites that significantly increased with large HCC were glutamate, acetate, and N-acetyl glycoproteins, whereas metabolites that correlated with cirrhosis were lipids and glutamine. Projection of small HCC samples into the OPLS model showed a heterogeneous distribution between large HCC and cirrhotic samples. Small HCC patients with metabolomic profile similar to those of large HCC group had higher incidences of recurrence or death during follow-up. Conclusions: SerumNMR-basedmetabolomics identifiedmetabolic fingerprints that couldbe specific to large HCC in cirrhotic livers. From a metabolomic standpoint, some patients with small HCC, who are eligible for curative treatments, seem to behave as patients with advanced cancerous disease. It would be useful to further prospectively investigate these patients to define a subgroup with a worse prognosis. Clin Cancer Res; 18(24); 1–9. 2012 AACR.
