Analytic Study Of The Trend Of Ghanas GDP Before And After Re-basing

The fourth republican constitution came into force in 1993. Ghana statistical Service also re-based Ghanas GDP in the same year. From 1993 to 2005, the average GDP growth rate was about 4.3%. Within the period of 1993 and 2005, Ghana was still below the lower middle income level. Another re-basing took place in 2006. It is now believed that we are in the lower middle income level. The study was conducted to develop mathematical models to predict the trend of Ghanas GDP before re-basing and after re-basing in 2006, use the models before and after re-basing to predict the future trend in Ghanas GDP growth, compare our GDP growth before re-basing and after re-basing, to determine whether or not, there are fluctuations in our GDP growth and predict Ghanas per capita income status in 2015. Data on Ghanas GDP were collected from the Statistical Service Department. The GDP figures from 1993-1995 and from 1996-2010 were plotted separately on graphs. A function whose graph best fits each trend was found using regression analysis. It was observed that Ghanas GDP trends before and after re-basing was exponential. There were also no fluctuations in the growth of the economy. Ghana may still be in the lower middle income status by 2015

Processing of time reference in agrammatic speakers of Akan:A language with grammatical tone

Background: Languages of the world have several ways of expressing time reference. Many languages such as those in the Indo-European group express time reference through tense. Languages such as Chinese and Standard Indonesian express time reference through aspectual adverbs, while Akan does so through grammatical tone. Previous studies have found that time reference is selectively impaired, with reference to the past being more impaired than reference to the non-past. The PAst DIscourse LInking Hypothesis (PADILIH) posits that pastime reference is difficult because it requires discourse linking. Aims: The goal of this study was first to examine whether pastime reference is impaired also in languages that do not use grammatical affixes but rather tone, to make time reference. Second, this study aims to decouple the effect of tone from the effect of temporal reference on Akan verbs. Method and Procedures: Ten Akan agrammatic speakers and 10 non-brain-damaged speakers (NBDs) participated in this study. An Akan adapted version of the Test for Assessing Reference of Time (African TART), for both production and comprehension was used. The TART focuses on the future, present (habitual) and the pastime frames. Additionally, five of the agrammatic speakers performed two tonal discrimination tasks: a non-linguistic and a linguistic (lexical) one. Outcomes and Results: While the NBDs scored at ceiling, the agrammatic speakers made errors, and these affected past more than present and the future time references, in both comprehension and production tasks. However, the comprehension data showed a dissociation between the present habitual and the future. The substitution error analysis revealed a preference for the present. The five agrammatic speakers showed an intact performance on non-linguistic tonal discrimination task. Conclusion: The conclusion is that regardless of how time reference is expressed, whether through inflectional morphology or grammatical tone, reference to the past is problematic for individuals with agrammatic aphasia. The fact that the agrammatic speakers could perceive the non-linguistic tonal differences demonstrates that it is not tone in general that is disrupted, but rather time reference, particularly reference to the past, as predicted by the PADILIH

Community service providers' roles in supporting communication disability rehabilitation in Majority World contexts: An example from Ghana

Purpose: In Majority World countries, where speech-language pathology services are extremely limited, people with communication disabilities (PWCD) may seek help from a range of service providers. This qualitative research aimed to explore the nature of community services offered to people with communication disabilities who seek help in Accra, Ghana. Method: Semi-structured interviews were conducted with nine individuals from three professions: pastors (3), doctors (3), and herbalists (3) exploring services that they may offer to PWCD seeking help. Interviews were analysed using Thematic Network Analysis. Result: Six global themes described beliefs about communication disability, types of intervention, explanations provided to people with communication disabilities, promoting communication, processes for selecting treatments, and links between service providers. Interventions encompassed physical, spiritual, psychosocial and environmental approaches, with the notion of plural beliefs interwoven through a number of themes. Conclusion: In Ghana, and other Majority World contexts, service providers in sectors not commonly associated with communication disability rehabilitation may have important roles to play in supporting people with communication disabilities. Understanding the contributions of other service providers may assist the growing profession of speech-language pathology to collaborate across sectors, to develop specific, culturally responsive approaches to service development

Sustainable partnerships for communication disability rehabilitation in Majority World countries. A message from the inside

Rehabilitation services for people with communication disabilities (PWCD) in many majority-world countries are extremely limited, with speech-language pathology little known. Collaborations between clinicians and services in majority- and minority-world countries provide important contributions to developing rehabilitation services in the majority world for PWCD. The effectiveness of such partnerships may be influenced by a number of elements within the relationship. This paper presents insights from a group of majority-world speech-language pathologists (SLPs) in Ghana on establishing and maintaining links between majority- and minority-world services and clinicians. The framework of three sustainability dimensions (service environment, socio-cultural-political environment, and economic environment) is used to consider how SLP relationships across majority–minority worlds can be meaningful and lasting. Readers are encouraged to adopt the perspective of SLPs from within the country to consider the impact and sustainability of majority–minority world partnerships

Resumption in the production of focused constructions in Akan speakers with agrammatism.

Background: The distribution of pronouns varies cross-linguistically. This distribution has led to conflicting results in studies that investigated pronoun resolution in agrammatic indviduals. In the investigation of pronominal resolution, the linguistic phenomenon of "resumption" is understudied in agrammatism. The construction of pronominal resolution in Akan presents the opportunity to thoroughly examine resumption. Aims: To start, the present study examines the production of (pronominal) resumption in Akan focus constructions (who-questions and focused declaratives). Second, we explore the effect of grammatical tone on the processing of pronominal (resumption) since Akan is a tonal language. Methods & Procedures: First, we tested the ability to distinguish linguistic and non-linguistic tone in Akan agrammatic speakers. Then, we administered an elicitation task to five Akan agrammatic individuals, controlling for the structural variations in the realization of resumption: focused who-questions and declaratives with (i) only a resumptive pronoun, (ii) only a clause determiner, (iii) a resumptive pronoun and a clause determiner co-occurring, and (iv) neither a resumptive pronoun nor a clause determiner. Outcomes & Results: Tone discrimination .both for pitch and for lexical tone was unimpaired. The production task demonstrated that the production of resumptive pronouns and clause determiners was intact. However, the production of declarative sentences in derived word order was impaired; wh-object questions were relatively well-preserved. Conclusions: We argue that the problems with sentence production are highly selective: linguistic tones and resumption are intact but word order is impaired in non-canonical declarative sentences

Quinine Sulphate Microparticles as Treatment for Leishmaniasis

Background. Leishmaniasis is a neglected tropical disease caused by the Leishmania parasite and transmitted by the female phlebotomine sandfly. The disease can affect the skin (least fatal) or internal organs (most fatal). Current treatment options for leishmaniasis have a number of adverse effects, and there appears to be resistance by the protozoan parasite (Leishmania spp.). Reports suggest that quinine sulphate, not indicated for leishmaniasis, is effective in killing the Leishmania parasite. Indeed, the efficacy of any drug is dependent on the concentration at the target site, which is also almost dependent on drug formulation. The current study assessed the pharmacokinetic profile of the microparticulate formulation of quinine sulphate and its in vitro and in vivo efficacy against Leishmania donovani. Methods. Quinine sulphate was encapsulated in bovine serum albumin by the spray-drying method. Quinine sulphate microparticles were evaluated for size, zeta potential, drug content, encapsulation efficiency, and in vitro release properties. Afterwards, the pharmacokinetic characteristics of quinine sulphate microparticles were estimated and in vivo efficacy studies were also conducted. Results. The size range of the quinine sulphate microparticles was between 2.0 and 5.0 µm. Microparticles had an average zeta potential of −35.2 mV and an encapsulation efficiency of 94.5%. Also, Cmax, t1/2, and AUC were all significantly desirable for quinine sulphate microparticles compared to the drug powder. Quinine sulphate microparticles significantly reduced parasite load in rat organs than amphotericin B. Conclusion. Overall, quinine sulphate microparticles had better pharmacokinetic profile and showed higher efficacy against Leishmania donovani parasites in vivo. Thus, quinine sulphate microparticles have the potential, especially, in treating visceral leishmaniasis

Trace Metals in Cannabis Seized by Law Enforcement in Ghana and Multivariate Analysis to Distinguish among Different Cannabis Farms

For hundreds of years, cannabis has been one of the most known cultivated plants due to its variety of uses, which include as a psychoactive drug, as well as for medicinal activity. Although prohibiting cannabis products, the countries of the African continent are the largest producers of cannabis in the world; a fact that makes the trafficking of cannabis-based illicit drugs a high priority for local law enforcement authorities. The latter are exceedingly interested in the use of chemical analyses for facilitating quantification, identification, and tracing of the origin of seized cannabis samples. Targeting these goals, and focusing on the country of Ghana, the present study used inductively coupled plasma mass spectrometry (ICP-MS) for the determination of 12 elements (Pb, Cu, Ca, Mg, Mn, Zn, Cd, As, Hg, Fe, Na, and K) in cannabis seized by Ghana’s law enforcement authorities and soils of cannabis farms. Furthermore, multivariate analysis was applied to distinguish among different cannabis farms and match them with the samples. As a result, 22 seized cannabis samples and 12 other cannabis samples with their respective soils were analyzed to reveal considerable As and Pb concentrations. As and Pb levels in cannabis were found up to 242 ppb for As and 854 ppb for Pb. Multivariate analysis was applied for separating different cannabis farms and seized samples based on elemental analysis, evidently linking the seized samples with two Ghana regions
