Modern Economy (ME) , 2016, DOI: 10.4236/me.2016.712134
Abstract: Revenues generated from taxes constitute a major source of income for governments. However, the epic display of tax evasion by individuals and firms in most countries has induced researches on the factors accounting for tax evasion in developing countries. Therefore, this study is conducted to investigate the determinants of the informal sector compliance issues and the causality nexus between tax evasion and Gross Domestic Product (GDP). This research solely adopts the theory of planned behavior in analyzing tax compliance issues. The research work is divided into two parts. In analyzing the informal sector compliance issues, questionnaires were submitted to 600 respondents comprising informal sector taxpayers in all the ten regions in Ghana. Regression analysis was employed in our study to depict the results of the informal sector compliance issues. The result revealed that attitudes, subjective norm and perceived behavioral control are the main determinants of the informal sector compliance issues. The second part of this research examined the causality between taxes and GDP in Ghana’s economy over the period of 1980-2015. The data were analyzed by employing the Augmented Dickey Fuller Unit Root test, the variables were found to be integrated of the order one and the Johansen test showed the presence of co-integration between the variables. The Granger causality test for the study indicated a unidirectional causality from taxation to GDP. Therefore, the study recommends that efforts should be geared towards the improvement of tax systems in order to augment the GDP of the country.

Abstract: Electricity plays a crucial role in the economic development of most economies. The causality nexus between electricity consumption and economic growth is important in enacting energy consumption policy and environmental policy. Many researchers have studied the causality between energy consumption and economic growth yet no consensus has emerged. Irrespective of the numerous researches conducted between these two variables, less evidence has been recorded in Ghana. Studies establishing the direction of causality between economic growth and energy consumption have concluded mixed result posing stern threat to Ghana’s energy policy. It is therefore viable to investigate the direction of causality between electricity consumption and economic growth in Ghana. This study uses the Cobb-Douglas growth model covering time series data from 1970 to 2014. Vector Error Correction Model was also conducted in order to empirically ascertain the error correction adjustment. Granger Causality test was used to determine the direction of causality between electricity consumption and economic growth and the empirical findings obtained herein reveals that there exists a unidirectional causality running from GDP to electricity consumption. This line of causality obtained from the data supports Growth-Led-Energy Hypothesis. Therefore, it is evident that Ghana is a less energy-dependent economy.

Journal of Science and Technology (Ghana) , 2012,
Abstract: Candidal vulvovaginitis causes extreme discomfort and affects the well being of women. The aim of this study was to determine the prevalence of Candida infections among women attending gynaecological clinic at the Komfo Anokye Teaching Hospital (KATH) in Kumasi and the antifungal susceptibility patterns of the Candida species isolated. A total of 186 high vaginal swabs (HVS) were collected from women suspected of having candidal vulvovaginitis between March and June 2009. Wet mount preparations in potassium hydroxide (KOH) and Gram-stained smears were performed directly on specimens. Cultures for Candida species were done using sabouraud dextrose agar (SDA) (Oxoid, UK) at room temperature (25 - 28oC). Antifungal susceptibility of the Candida species to amphotericin B, fluconazole and itraconazole was assessed using the ATB FUNGUS 3 test kits (bioMerieux, Marcy-l’Etoile, France). Of the 186 HVS cultured, 39 yielded Candida species giving Candida prevalence in HVS during the study period as 21%. Candida species isolated from HVS specimens were Candida albicans (n=19, 48.7%), Candida glabrata (n=7, 17.9%), Candida tropicalis (n=4, 10.3%) and Candida dubliniensis (n=4, 10.3%). Other species isolated were Candida sake (n=2, 5.1%), Candida krusei (n=2, 5.1%) and Candida parapsilosis (n=1, 2.6%). Susceptibility of the isolates to antifungal agents ranged from 66.7% to 87.2% with MICs ranging from ≤ 0.125mg/l to 8mg/l. Amphotericin B was the best performing antifungal agents with sensitivity of 87.2%.
Perversion and pathology: a critique of psychoanalytic criticism in art
Lucille Holmes
Journal of Aesthetics & Culture , 2012, DOI: 10.3402/jac.v4i0.19038
Abstract: For over three decades, Jacques Lacan denounced ego psychology for its emphasis on a strong and well-adapted ego. This article recruits the principle of that critique to examine the use of psychoanalytic theories in contemporary art criticism, with specific focus on the subject of perversion, Freudo-Lacanian psychoanalysis, and the work of art critic Donald Kuspit. The discussion examines the main influences and concepts in Kuspit's psychoanalytic criticism, analyses specific differences between this psychoanalytic model and a Lacanian theory of perversion and desire, and considers the effect of these differences in the interpretation of art.
Portfolio langagier : Les finissants des programmes d’immersion se révèlent
Lucille Mandin
Canadian Journal of Applied Linguistics (CJAL) , 2010,
Abstract: This article presents a research conducted with French Immersion graduates in the context of an introductory language methodology course in a francophone institution. The participants completed a language portfolio, created by Laplante & Christiansen (2001). The portfolio consisted of a two-page autobiographical narrative entitled 'My Life in French till now', an action plan which included an analysis of the errors they identified as targets for that semester and the means or the tools they chose to correct the errors. An analysis of the autobiographical narrative, a document written by the individual participants, stemming from their life experiences since they were exposed to the French language, is presented. The narrative is inspired by the values they have developed and the choices they have made concerning learning French (Baumeister, 1991; Kenyon, 1999). This study also presents a profile of significant experiences these French Immersion graduates identify as pivotal in their motivation to pursue their postsecondary studies in French. They also highlight teachers, friends and family who played an important role during 'their lives in French' till now. In their action plan, the students identified categories of linguistic challenges in areas such as semantics, syntax and phonology. These results shed light on questions pertaining to best practices in French Immersion programs.

Ghana Medical Journal , 2008,
Abstract: Objective: The analgesic activity of crude aqueous extract of the root bark of Zanthoxylum xanthozyloides was studied in mice and rats with the view to verifying the claim in folklore medicine that the extract has analgesic activity. Method: The extract was obtained by Soxhlet extraction and rotatory evaporation, followed by freezedrying. Groups of rats and mice were, respectively, assigned randomly to treatment groups. The animals received three different treatments orally: 0.9% saline (control), the extract (400mg/kg and 800mg/kg for mice; 1000mg/kg and 2000mg/kg for rats) and indomethacin (5mg/kg and 10mg/kg for mice; 10mg/kg and 20mg/kg for rats). Each group of animals was rotated through the entire treatment groups such that each animal served as control as well as received all the treatments. The hot-plate and paw-pressure methods were used to study pain perception in the treated animals. Analysis of variance was used as the statistical test. Results: In both methods, the extract and indomethacin caused dose-dependent elevation in pain threshold. At the peak of activity, 400mg/kg and 800mg/kg extract caused 74% and 95% increase in the reaction time respectively whilst 5mg/kg and 10mg/kg indomethacin gave 97% and 116% increment respectively. Similarly, 1000mg/kg and 2000mg/kg extract caused 65% and 84% increase in pain threshold whilst 10mg/kg and 20mg/kg indomethacin caused 95% and 113% increment respectively. Conclusion: It was concluded that the extract induced analgesia, probably, by inhibiting prostaglandin production, just as did indomethacin.

A Hessenberg generalization of the Garsia-Procesi basis for the cohomology ring of Springer varieties
Aba Mbirika
Mathematics , 2009,
Abstract: The Springer variety is the set of flags stabilized by a nilpotent operator. In 1976, T.A. Springer observed that this variety's cohomology ring carries a symmetric group action, and he offered a deep geometric construction of this action. Sixteen years later, Garsia and Procesi made Springer's work more transparent and accessible by presenting the cohomology ring as a graded quotient of a polynomial ring. They combinatorially describe an explicit basis for this quotient. The goal of this paper is to generalize their work. Our main result deepens their analysis of Springer varieties and extends it to a family of varieties called Hessenberg varieties, a two-parameter generalization of Springer varieties. Little is known about their cohomology. For the class of regular nilpotent Hessenberg varieties, we conjecture a quotient presentation for the cohomology ring and exhibit an explicit basis. Tantalizing new evidence supports our conjecture for a subclass of regular nilpotent varieties called Peterson varieties.

Abstract: Background: Malaria infection during pregnancy is a major public health problem in tropical and subtropical regions globally. Anaemia is often an adverse outcome of severe parasitic infections during pregnancy in developing countries. Pregnant women in malaria-endemic communities are more susceptible to Plasmodium falciparum infections than non-pregnant women of child-bearing age. Objective: To comparatively investigate malaria and anaemia in pregnant and non-pregnant women of child-bearing age. Design: A cross-sectional comparative study. Three hundred and eighty pregnant women and 380 non-pregnant women were screened for the study. Setting: The study was conducted at the University Hospital, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana. Measurements: Participants’ demographic data were collected via the administration of questionnaires. In addition their blood samples were analyzed for haemoglobin level and malaria parasites, while stool samples from the pregnant women were examined for intestinal parasites. Results: The study revealed that pregnant women have higher malaria parasitaemia (12.6%) and anaemia (62.6%). The species of Plasmodium isolated from the pregnant women were P. falciparum (85.4%), P. malariae (4.2%) and P. ovale (10.4%). Malaria parasitaemia was higher in the primigravidae (14%). However multigravidae recorded the highest anaemia prevalence (67.1%). Age of pregnant women was a factor affecting malaria parasitaemia with a significant P-value and OR (P value = 0.0041, 0R = 7.61). Conclusions: Pregnant women were more susceptible to malaria and anaemia than non-pregnant women of child-bearing age. Most of the pregnant women reported at antenatal clinic during the second trimester. Primigravidae however recorded the highest malaria parasitaemia. The main species of Plasmodium observed in the blood samples was falciparum.
