Economic development and change in Tanzania since independence : The political leadership factor Honest

The author makes a critical examination of the contribution of political leadership in the economic development and change of Tanzania since her 1961 political independence from Britain. He divides the country’s economic development and change into three more or less discrete time epochs. The first epoch is the period from independence to 1967; the second is from the 1967 Arusha Declaration to the mid-1980s and the third is from the mid-1980s reforms to the present time (2007). The outstanding general economic developments and change in each epoch are identified. A critical analysis on the extent to which the developments and change in each epoch can be attributed to the political leadership of the time or even of the past is made. It is found in the work that, the economic developments and change in Tanzania can be highly attributed to political leadership. Interestingly and contrary to the orthodox understanding and narrow scope of some analyses, both the political leadership of the day and that of the past are found to be responsible for economic developments and change in a particular epoch. Interestingly also, it is found that political leadership outside Tanzania, especially among its neighbours, trade partners and the donor community, has far-reaching impacts in the country’s economic development and change. It is concluded in the paper that political leadership is an important factor in a country’s development and change. It is recommended that policy and decision makers should facilitate a process where adequate political leadership for good development and change is established, improved and maintained. Recommendations for further studies include the need to review this work over time and conduct similar ones in other countries for the purpose of, interalia, comparisons and learning lessons.

Direct Evidence of Dividend Tax Clienteles

We study a large data set of stock portfolios held by individuals and organizations in the Swedish stock market. The dividend yields on these portfolios are systematically related to investors' relative tax preferences for dividends versus capital gains. Tax-neutral investors earn 40 basis points higher dividend yield on their portfolios than investors which face higher effective taxation of dividends than capital gains. We conclude that there are dividend tax clienteles in the market. We also argue that the abundant portfolio holdings by closely-held corporations, despite triple taxation at a combined marginal tax rate as high as 77.5%, is a consequence of taxation.
Complete repair of dystrophic skeletal muscle by mesoangioblasts with enhanced migration ability

Efficient delivery of cells to target tissues is a major problem in cell therapy. We report that enhancing delivery of mesoangioblasts leads to a complete reconstitution of downstream skeletal muscles in a mouse model of severe muscular dystrophy (α-sarcoglycan ko). Mesoangioblasts, vessel-associated stem cells, were exposed to several cytokines, among which stromal- derived factor (SDF) 1 or tumor necrosis factor (TNF) α were the most potent in enhancing transmigration in vitro and migration into dystrophic muscle in vivo. Transient expression of α4 integrins or L-selectin also increased several fold migration both in vitro and in vivo. Therefore, combined pretreatment with SDF-1 or TNF-α and expression of α4 integrin leads to massive colonization (>50%) followed by reconstitution of >80% of α-sarcoglycan–expressing fibers, with a fivefold increase in efficiency in comparison with control cells. This study defines the requirements for efficient engraftment of mesoangioblasts and offers a new potent tool to optimize future cell therapy protocols for muscular dystrophies.
A STUDY OF THE RPC MODEL OF TERRASAR-X AND COSMO-SKYMED SAR IMAGERY

The rational polynomial coefficient (RPC) model has recently raised considerable interest in the photogrammetry and remote sensing community. This model is a generalized sensor model that is capable of achieving high approximation accuracy. Unfortunately, in all previous literature, the computation of the parameters of the RPC model depends on initial values for the parameters. In this paper, an algorithm for the computation of the parameters without these initial values is presented. Finally, the algorithm is tested on TerraSAR-X and COSMO-SkyMed SAR imagery. Based on numerous tests, the following conclusion can be drawn. This study found that the RPC model is suitable for high resolution SAR imagery. * Corresponding author.
The Advent of Practice Theories in Research on Sustainable Consumption: Past, Current and Future Directions of the Field

The application of practice theories in the domain of sustainability research in consumer studies is increasingly advocated based on the premise that this allows to analyse consumption as a social phenomenon. Consequently, the applications of social practice theories to this field are expanding geometrically and to date, little retrospective work on this evolution has been made. We conduct a bibliometric analysis of applications of practice theories in the domain of sustainability research in consumer studies. Our results show a temporal succession of research trends: ‘consumer identity’ dominated the field between 2009 and 2012, ‘business and governance’ between 2012 and 2014, ‘sustainable consumption and production’ between 2013 and 2014, ‘urban living and policy’ between 2014 and 2015 and ‘household energy’ from 2015 until the present. We see a high potential of future applications of practice theories in the fields of the sharing and circular economy, as well as in research on smart cities. We provide new insights into the evolution and future trends of applications of social practice theory to domains that are relevant for research on sustainability and consumer studies.
Diffusion-weighted magnetic resonance imaging in a case of cerebral venous thrombosis.

BACKGROUND Diffusion-weighted imaging (DWI) is the most sensitive MR sequence in acute arterial ischemic stroke but has not yet been evaluated in venous cerebral ischemia. We describe a patient with DWI performed at the acute phase of a venous ischemic stroke. CASE DESCRIPTION A rapid cerebral MRI including DWI and fast fluid-attenuated inversion recovery (FLAIR) sequences was performed at the acute phase of a venous stroke confirmed by conventional angiography. DWI showed a slight decrease in apparent diffusion coefficient values 3 hours after onset (0.53+/-0.07x10(-3) mm2/s) and was normal 48 hours later (0.064+/-0.15x10(-3) mm2/s). Fast FLAIR sequences showed large left frontoparietal hyperintensities. The lack of a clear decrease in apparent diffusion coefficient values associated with marked FLAIR abnormalities may suggest prominent or early associated vasogenic edema. Physiopathological differences between arterial and venous ischemia may explain the different type of DWI FLAIR abnormalities during the acute phase as well as the better recovery of neurological deficit in venous stroke than in arterial ischemic stroke. CONCLUSIONS In the context of an acute stroke, the contrast between marked FLAIR and subtle DWI abnormalities on MRI may reflect the venous mechanism of cerebral ischemia.
Unemployment and Labor Market Rigidities: Europe versus North America

The received wisdom tells us that the rigidity and inflexibility of European job markets relative to that in the United States is the reason why Europe has high unemployment. This paper argues that this broad brush analysis is simply too vague to be useful. Indeed it is probably positively misleading. Many labor market institutions that conventionally come under the heading of rigidities have no observable impact on unemployment and may otherwise serve a useful purpose.
Repeated Web Page Visits and the Scanpath Theory: A Recurrent Pattern Detection Approach

This paper investigates the eye movement sequences of users visiting web pages repeatedly. We are interested in potential habituation due to repeated exposure. The scanpath theory posits that every person learns an idiosyncratic gaze sequence on first exposure to a stimulus and re-applies it on subsequent exposures. Josephson and Holmes (2002) tested the applicability of this hypothesis to web page revisitation but results were inconclusive. With a recurrent temporal pattern detection technique, we examine additional aspects and expose scanpaths. Results do not suggest direct applicability of the scanpath theory. While repetitive scan patterns occurred and were individually distinctive, their occurrence was variable, there were often several different patterns per person, and patterns were not primarily formed on the first exposure. However, extensive patterning occurred for some participants yet not for others which deserves further study into its determinants.
Kobe University Repository : Kernel タイトル Tit le Case Reports of Unexpected Suicides in Pat ients within Six Months after Stroke 著者

Suicide after stroke is a grievous occurrence. Since the majority of cases under study had shown signs of recovery from stroke, persons surrounding these patients were severely shocked by these suicides. Six patients who attempted suicide within six months after stroke were investigated to determine factors following stroke that relate to suicide in order to prevent future post-stroke suicides. Clinical findings in these six cases were retrospectively analyzed in collaboration with stroke neurologists and coworkers caring for these patients. Four of six patients had sustained a recent infarction extending from the temporal cortex to the parietal cortex. Four of six patients showed depression, and five of six patients showed moderate disability after stroke. Physicians should carefully observe patients with infarction extending from the temporal cortex to the parietal cortex, depression and moderate disability, in order to prevent suicidal behavior.
Market Efficiency and News Dynamics: Evidence from International Equity Markets

This paper examines the efficient market hypothesis by applying monthly data for 15 international equity markets. With the exceptions of Canada and the U.S., the null for the absence of autocorrelations of stock returns is rejected for 13 out of 15 markets. The evidence also rejects the independence of market volatility correlations. The null for testing the absence of correlations between stock returns and lagged news measured by lagged economic policy uncertainty (EPU) is rejected for all markets under investigation. The evidence indicates that a change of lagged EPUs positively predicts conditional variance.
The Character Skills of Immigrants

We use novel data on a representative sample of the U.S. population to examine how immigrants and second-generation immigrants compare to natives on non-cognitive character skills as measured by a common taxonomy of personality. Our findings reveal that immigrants and second-generation immigrants tend to have higher levels of openness to experience and agency than natives. Additionally, second-generation immigrants have higher levels of conscientiousness than natives. The findings are especially salient since character skills have been shown to influence labor market outcomes. Next, we examine the role of character skills differences on earnings by immigrant generation. Our earnings estimates reveal that non-cognitive skills have approximately as much explanatory power as schooling, yet non-cognitive skills have a modest impact on the earnings differences of immigrants and second-generation immigrants vis-a-vis natives.
University of Groningen Antimicrobial Resistance in Class 1 Integron-Positive Shiga Toxin-Producing Isolated from Cattle , Pigs , Food and Farm Environment

The aim of this study was to investigate the presence of class 1 integrons in a collection of Shiga toxin-producing Escherichia coli (STEC) from different origins and to characterize phenoand genotypically the antimicrobial resistance associated to them. A collection of 649 isolates were screened for the class 1 integrase gene (intI1) by Polymerase chain reaction The variable region of class 1 integrons was amplified and sequenced. Positive strains were evaluated for the presence of antimicrobial resistance genes with microarray and for antimicrobial susceptibility by the disk diffusion method. Seven out of 649 STEC strains some to serogroups, O26, O103 and O130 isolated from cattle, chicken burger, farm environment and pigs were identified as positive for intl1. Different arrangements of gene cassettes were detected in the variable region of class 1 integron: dfrA16, aadA23 and dfrA1-aadA1. In almost all strains, phenotypic resistance to streptomycin, tetracycline, trimethoprim/sulfamethoxazole, and sulfisoxazole was observed. Microarray analyses showed that most of the isolates carried four or more antimicrobial resistance markers and STEC strains were categorized as Multridrug-resistant. Although antimicrobials are not usually used in the treatment of STEC infections, the presence of Multridrug-resistant in isolates collected from farm and food represents a risk for animal and human health.

Antibody Targeting to a Class I MHC-Peptide Epitope Promotes Tumor Cell Death

Therapeutic mAbs that target tumor-associated Ags on the surface of malignant cells have proven to be an effective and specific option for the treatment of certain cancers. However, many of these protein markers of carcinogenesis are not expressed on the cells’ surface. Instead these tumor-associated Ags are processed into peptides that are presented at the cell surface, in the context of MHC class I molecules, where they become targets for T cells. To tap this vast source of tumor Ags, we generated a murine IgG2a mAb, 3.2G1, endowed with TCR-like binding specificity for peptide-HLA-A*0201 (HLA-A2) complex and designated this class of Ab as TCR mimics (TCRm). The 3.2G1 TCRm recognizes the GVL peptide (GVLPALPQV) from human chorionic gonadotropin β presented by the peptide-HLA-A*0201 complex. When used in immunofluorescent staining reactions using GVL peptide-loaded T2 cells, the 3.2G1 TCRm specifically stained the cells in a peptide and Ab concentration-dependent manner. Staining intensity correlated with the extent of cell lysis by complement-dependent cytotoxicity (CDC), and a peptide concentration-dependent threshold level existed for the CDC reaction. Staining of human tumor lines demonstrated that 3.2G1 TCRm was able to recognize endogenously processed peptide and that the breast cancer cell line MDA-MB-231 highly expressed the target epitope. The 3.2G1 TCRm-mediated CDC and Ab-dependent cellular cytotoxicity of a human breast carcinoma line in vitro and inhibited in vivo tumor implantation and growth in nude mice. These results provide validation for the development of novel TCRm therapeutic reagents that specifically target and kill tumors via recognition and binding to MHC-peptide epitopes.
Synapse formation and preferential distribution in the granule cell layer by regenerating retinal ganglion cell axons guided to the cerebellum of adult hamsters

To investigate constraints and preferences for synaptogenesis in the injured mammalian CNS, regenerating retinal ganglion cell (RGC) axons of adult hamsters were guided through a peripheral nerve (PN) graft to a target they do not usually innervate: the cerebellum (Cb). When identified by the presence of HRP anterogradely transported from the retina 2–9 months later, such RGC axons were found to have extended into the cerebellar cortex for up to 650 microns. Most of this growth was in the granule cell layer (GCL) and only a few axons entered the molecular layer. The preference for the GCL could not be explained by the position of the PN graft in the Cb, a selective denervation of the GCL, local damage to other neurons, or the distribution of reactive gliosis in the vicinity of the graft. Furthermore, by EM, more than 95% of the labeled retinocerebellar terminals and synapses were in the GCL. Retinocerebellar terminals were larger and contained more synapses than the regenerated RGC terminals previously studied in the superior colliculus. These results indicate that regenerating axons of CNS neurons can form persistent synapses with novel targets. The preferential synaptogenesis in the GCL suggests that such unusual connections are not formed randomly in the CNS of these adult mammals.
An Ethical Investments Evaluation for Portfolio Selection

The Socially Responsible Investing (SRI) is an assets allocation, whose aim is to maximize not only the portfolio expected return but the benefits for a consumer who as a whole operates according to the ethical principles. The wealth of a market economy is to cross the different ethical identities of families, of enterprises, of banks, in order to improve the allocation of the resources for a sustainable development. In this paper, we aim at describing the portfolio selection realized on the basis of the ethical principles positive /negative, inclusionary/exclusionary of an investor. The first part of this paper describes Socially Responsible Investing (SRI) and ethical funds market in the world; the second part builds an ethical index as evaluation of the coherence of the ethical principles of the investor in comparison with the ethical principles respected in the investment. The paper also illustrates the set of admissible portfolios for an ethical investor, obtained on the basis of the following indexes of risk, of expected return and of ethicality. Key-words Socially responsible investing, ethical screening, portfolio theory
Geographic Concentration and Vertical Disintegration : Evidence from China ♣

Existing theoretical literature predicts that geographic concentration encourages vertical disintegration of firms. Nevertheless, empirical evidence of this prediction is limited, especially in developing countries. Using data on manufacturing firms from China, this paper documents a positive correlation between geographic concentration and vertical disintegration. Additionally, this paper uses the instrumental variable approach to address the issue of endogeneity and finds that geographic concentration has a positive causal effect on vertical disintegration.
TRIM59 is a novel potential prognostic biomarker in patients with non-small cell lung cancer: A research based on bioinformatics analysis

Lung cancer is the leading cause of cancer-associated mortality worldwide and its prognosis is poor. Few effective biomarkers for non-small cell lung cancer (NSCLC) have been translated into the clinical practice aiming to assist in the treatment plan design and prognosis evaluation. The aim of the present study was to identify novel potential prognostic biomarkers for NSCLC. Tripartite motif 59 (TRIM59) was identified from a microarray dataset of matched-samples and was verified as an aberrantly upregulated gene in NSCLC tissue. The expression level of TRIM59 in NSCLC subtypes was observed to be significantly increased in large cell lung carcinoma and squamous cell carcinoma as compared with that in adenocarcinoma. Its expression correlated with several clinicopathological features, including gender, smoking habits, and unfavorable tumor node and pathological stages. Notably, TRIM59 demonstrated a negative correlation with survival time and its overexpression indicated a poor prognosis in NSCLC. Furthermore, univariate and multivariate Cox's regression analyses indicated that TRIM59 was an independent prognostic factor in tumor tissue as compared with age, gender, tumor stage, node stage, and metastasis. Gene set enrichment analysis and protein-protein interaction network construction revealed that TRIM59 was associated with oncogenic mammalian target of rapamycin (MTOR) and eukaryotic initiation factor 4E (EIF4E) signaling through ubiquitin C binding. In conclusion, it was revealed that TRIM59 is a novel prognostic biomarker modulating oncogenic MTOR and EIF4E signaling pathways in NSCLC. These findings provided a novel insight into the clinical application of TRIM59. Therefore, TRIM59 may serve as an independent predictor for prognosis and a potential therapeutic target for NSCLC.
