Mother tongue, first language or native language? In English, these are the terminologies used for the Hungarian word “anyanyelv”. In Hungarian, mother tongue, first language and native language describe the same thing in most cases. In a multilingual family the languages can characterize both the father’s and mother’s country. Through a language one can study the culture and tradition of a nation, as well as his or her own family. A child who knows both the father’s and mother’s languages may have two ‘motherlands’. This can expand his or her understanding of the world and their international social interactions, especially in situations where the parents come from different continents. In this article we assess a Ghanaian-Hungarian family where the children can speak three languages paying attention to the advantage and disadvantages of multilingualism in such families. We also stress on the efforts needed to raise children in multilingual families.

“Togetherness in Difference”: Perceived Personal Discrimination and Acculturation Preferences among Internal Migrants in a Poor Urban Community in Accra

This paper assesses the relative effects of acculturation preferences (assimilation, separation, integration, and marginalization) on migrants’ perception of acceptability in James Town, a traditional urban neighborhood in Accra, Ghana. There is a paucity of academic work on the relationship between migrants’ acculturation inclinations and their assessment of the hosts’ attitude towards them in Ghana. Cognizant of the fluidity of acculturation strategies, the study focuses on individual inclinations towards acculturation. To examine migrants’ perception of acceptability by the host, we use perceived personal discrimination. We utilize results from a semi-structured questionnaire administered to 301 migrant individuals from different migrant households in James Town. Our findings suggest that migrants with assimilation preferences are less likely to have a higher rating on the extent to which they are discriminated against by the host population. Such an exploratory study is pertinent to understanding relationships (conflicts or “togetherness in difference”) in poor multi-ethnic settings.

Token reflexive, anaphoric and deictic uses of ‘ here’

There are basically three ways in which the reference of a token of the English proximal spatial indexical here and corresponding terms in other languages can be resolved in the context-dependent, pragmatic phase of the addressee’s determination of the propositional content of an utterance that contains this adverbial adjunct. ‘Here’ may refer reflexively to the place of utterance, including minimally the spot occupied by the speaker (token-reflexive reference), it may be anaphoric upon a discourse antecedent that provides information necessary for identification of the referent (anaphoric reference), or resolution of the reference depends on information derived from processing of perceptual stimulus (deictic reference). These three pragmatic paths to resolution of the reference of proximal spatial indexicals are not mutually exclusive, so they do not warrant postulation of lexical ambiguity, at least not the traditional kind of ambiguity based on differences in conceptual meaning.

Tomato (Solanum lycopersicum L.) Genotypes Respond Differently to Long-Term Dry and Humid Heat Stress

Tomato production in coastal areas in West Africa is constrained by heat stress. There is currently limited empirical evidence on the extent of the effect of heat stress on tomato yield in the sub-region. In this study, we assessed the effects of heat stress on yield and yield components among 16 tomato genotypes with varying heat tolerance status and explored the potential of stress tolerance indices to identify heat tolerant genotypes. The experiments were conducted under three temperature and humidity regimes, namely optimal season (28.37/23.71 C and 71.0/90.4% day/night), long-term mild and humid (greenhouse, 30.0/26.2 C and 77.6/97.2%), and long-term mild and dry (open field, 31.50/28.88 C and 66.72/77.82%) heat stress (HS). All genotypes exhibited significantly higher fruit set percentage, fruit number per plant, fruit weight, and fruit weight per plant in the optimal season compared to both heat stress conditions. In general, the genotypes demonstrated higher performance under dry HS (i.e., HS in open field HSO) than humid HS (i.e., HS in greenhouse HSG). Fruit set decreased by 71.5% and 68.3% under HSG and HSO, respectively, while a reduction of 75.1% and 50.5% occurred in fruit weight per plant under HSG and HSO, respectively. The average sum of ranks values from nine stress tolerance indices and fruit weight per plant (used as proxy trait of yield) identified CLN2498D, CLN3212C, CLN1621L, and BJ01 as heat tolerant under HSG and BJ01, BJ02, Fla.7171, and P005 as heat tolerant under HSO. Fruit weight per plant under long-term heat stress (Ys) and optimal growing conditions (Yp) were suitable to select high performing genotypes under HSO, HSG, and optimal conditions while relative stress index, yield stability index, yield index, stress susceptibility index, and harmonic mean were suitable to select heat tolerant genotypes under either HSG or HSO. Our findings shed light on the extent of the effect of HS on tomato production in the off-season in coastal areas in West Africa and provide new insight concerning the heat tolerance status of the evaluated tomato genotypes.

Tomorrow May Not Be Yours: Military Slang And Jargon As Linguistic Performance In Nigeria

This article explores the expressive use of slang and jargon by officers and men of the Nigerian Army in a bid to construct social identity, enforce discipline, and conform to work ethics. The study adopts linguistic ideology and community of practice theories, which are complemented by the notion of style as performance to provide frameworks for understanding military subjectivities and attitudes represented by these emblematic linguistic resources. Data were sourced through participant observation and semi-structured interviews with 30 participants. The study found that military slang and jargon help ease communication between officers and men as they index power, enhance solidarity, facilitate inclusion (and exclusion), and promote varied military subcultures. We conclude that situated language practices provide a site for linguistic creativity and the enactment of style that sustain meaningful relationships between personnel in the army. This linguistic practice, therefore, offers strong social capital in defining collective identities and professional belonging.

Too weak to lead: motivation, agenda setting and constraints of local government to implement decentralized climate change adaptation policy in Ghana

Local governments in developing countries are christened as proadaptation agents. However, global research effort has virtually ignored inherent adaptation policy implementation nuances in developing countries, ostensibly assuming that narratives from existing policy implementation literature could fill the void. Drawing on qualitative data from six LGs from Ghana, this paper examines the motivation, agenda setting processes and teething challenges constricting the implementation of decentralized climate change adaptation governance in Ghana. Though adherents of decentralization argue that local governments are more likely to conceive and implement proadaptation-related interventions, evidence from Ghana provides fascinating lessons. This paper shows that local governments’ ability to mainstream adaptation-related actions into local governance is constricted by taxonomy of local political economy issues and the “science-heaviness” of climate change. It concludes that local government are unlikely to be a fulcrum of adaptation governance as touted if reasonable efforts are not made at strengthening and broadening its resource basket.

Tool kits for the Sustainable Management of Ghana’s Riverine Biodiversity: an Overview

The Darwin Initiative funded project Tool kits for the Sustainable Management of Ghana’s Riverine Biodiversity was a collaboration between the Centre for African Wetlands at the University of Ghana, various units of the University of Ghana and the Ghana Wildlife Society. The project also involved collaborators from Burkina Faso, Nigeria, Cote d’Ivoire, Togo and Benin. The project aimed to address the impediments that remain for Ghana (and its neighbouring countries) in applying the Ecosystem Approach (EA) to riverine wetland management and the delivery of the Convention on Biodiversity (CBD). Priority needs were identified as taxonomic capacity building, a contemporary assessment of the status of aquatic biodiversity in Ghana, the development of practical management tools for rivers and increased engagement of stakeholders in decision-making together with an enhanced environmental awareness throughout Ghanaian society. These were addressed in this project by regional and local staff training, reporting on the current status of aquatic communities, the production of educational and taxonomic resources for a range of users, the development of a set of nested indicators of ecosystem health adapted for use at various levels, and the production of a policy document outlining the means of applying the EA in the management of Ghana’s rivers.

“Top-down bottom-up” estimation of per capita cost of new-born care interventions in four regions of Ghana: beyond implementation to scalability and sustainability

Background: Limited financial, human and material health resources coupled with increasing demand for newborn care services require efficiency in health systems to maximize the available sources for improved health outcomes. Making Every Baby Count Initiative (MEBCI) implemented by local and international partners in 2013 in Ghana aimed at attaining neonatal mortality of 21 per 1000 livebirths by 2018 in four administrative regions in Ghana. MEBCI interventions benefited 4027 health providers, out of which 3453 (86%) were clinical healthcare staff. Objective: Determine the per capita cost of the MEBCI interventions towards enhancing new-born care best practices through capacity trainings for frontline clinical and non-clinical staff. Methods: Parameters for determining per capita cost of the new-born care interventions were estimated using expenditure on trainings, supervisions, monitoring and evaluation, advocacy, administrative/services and medical logistics. Data collection started in October 2017 and ended in September 2018. Data sources for the per capita cost estimations were invoices, expense reports and ledger books at the national, regional and district levels of the health system. Results: Total of 4027 healthcare providers benefited from the MEBCI training activities comprising of 3453 clinical staff and 574 non-clinical personnel. Cumulative cost of implementing the MEBCI interventions did not necessarily match the cost per capita in staff capacity building; average cost per capita for all staff (clinical and non-clinical staff) was approximately US$ 982 compared to a per capita cost of US$ 799 for training only core clinical staff. Average cost per capita for all regions was approximately US$ 965 for all staff compared to US$ 777 per capita cost for only clinical staff. Per capita cost of training was relatively lower in regions with more staff than regions with lower numbers, perhaps due to economies of scale. Conclusion: The MEBCI intervention had a wide coverage in terms of training for frontline healthcare providers albeit the associated cost may be potentially unsustainable for Ghana’s health system. Emerging digital training platforms could be leveraged to reduce per capita cost of training. Large-scale on-site batch-training approach could also be replaced with facility-based workshops using training of trainers (TOTs) approach to promote efficiency.

Topographic variables to determine the diversity of woody species in the exclosure of Northern Ethiopia

Exclosures are established with the objective of rehabilitating degraded lands and restoring of woody vegetation. Various studies have been conducted to evaluate the success of exclosure on restoring woody species diversity. However, works focusing on the effect of topographic factors on woody species diversity are scarce. Understanding the factors that determine woody species diversity is important for management purposes. Therefore, this paper analyzes the effect of altitude, slope, and aspect as topographic variables on woody species diversity in Dawsura exclosure in northern Ethiopia. Data on species identity, abundance, slope, elevation and aspect were recorded from 58 sampling plots. Different diversity indices were used to analyze the data and one-way ANOVA and linear regression was conducted. There were a total of 34 woody species represented 15 families, of which 62% and 38% were trees and shrubs respectively. Altitude (r2 ¼ 0.63, p ¼ 0.000 and r ¼ 0.794, p < 0.01) and slope (r2 ¼ 0.57, p ¼ 0.002 and r ¼ 0.68, p < 0.01) correlated significantly and positively with Shannon diversity, whereas aspect (r2 ¼ 0.12, p ¼ 0.378 and r ¼ 0.27, p > 0.05) did not correlate significantly with Shannon diversity. Woody species diversity at moderate (1.44) and high (1.85) altitudes was significantly different from that of low (0.86) altitude areas (p ¼ 0.0013). Furthermore, significantly higher woody species diversity was recorded at steep slope (1.88) and moderately steep slope (1.62) areas as compared to the gentle slope (0.95) areas. No significant variation was observed in woody species diversity among the aspect categories (p > 0.05). The study concludes that woody species diversity is largely regulated by slope and altitude than aspect in the exclosure. We suggest other environmental and anthropogenic variables should be taken into consideration in future studies on woody species diversity

A TOPSIS Extension Framework for Re-Conceptualizing Sustainability Measurement.

Purpose – The purpose of this paper is to propose a sustainability measurement and scoring system for assessing the efforts of organizations at meeting sustainability targets. Using technique for order preference by similarity to ideal solution (TOPSIS) as the basic framework, the proposed method incorporates all three sustainability dimensions – economic, environmental and social – to establish a threshold below which an organization is considered to have failed a sustainability test. In Addition, an introduction of a time-independent threshold enables a clearer comparison of performance of organizations over time. The proposed method includes plots for visualizing the sustainability performance of organizations under review. Design/methodology/approach – The proposed method first assigns target values to a hypothetical organization. TOPSIS is then used to generate composite scores in which the score of the hypothetical organization is set as the threshold below which organizations are deemed to have failed a sustainability test. Using the square of the closeness coefficient of TOPSIS, the final composite score is decomposed into three components to reflect the contribution of the three dimensions of sustainability to serve as a guide to determining which dimension to focus on for improvement. A relative comparison score is then proposed to track the performance of organizations over time. Findings – The proposed method with its ability to set a threshold is able to determine organizations that have passed a sustainability test from those that have failed. The tracking of organizational performance over time also serves to highlight progress being made by organizations to meet an agreed sustainability target. Results from the application of the proposed method for evaluating sustainability of banks under the three dimensions of sustainability highlight its practical applicability. The proposed method can also be applied to a wide range of comparison problems including make-or-by decisions and award selection. Practical implications – As most industries and organizations become conscious of the pressure to adopt sustainable practices, the proposed measuring system would help identify those that are meeting sustainability targets as well as to track their progress over time. Originality/value – Most sustainability measurement indicators rarely have thresholds to determine whether an organization has met or failed to meet a sustainability test other than ranking them from top to bottom. The proposed method provides a threshold as well as a procedure for tracking the sustainability performance of organizations over time.

Torn Between Two Worlds: Perceptions of the Role, Status, and Career Progression of Librarians Working in University Libraries

Librarians working in university libraries are torn between the two dominant categories (academic and pro fessional) of university staff. Belonging to either of the categories of staff has implications for the employees’ roles and duties, status, and career progression in the academic setting. This study sought to understand the perception of librarians’ roles, status, and career progression with the changing frontiers of knowledge and education in contemporary times. Using the qualitative approach, fourteen (14) librarians working in seven university libraries in Ghana were interviewed using a semi-structured interview schedule. These librarians were purposively selected because they possessed the qualifications of practice and were experienced in the academic library setting. The data collected from the interview was transcribed. Using Nvivo software version 14, the researchers used the Reflexive Thematic Analysis method to garner codes and themes from the data to under stand the phenomenon under study. The findings from the study showed that librarians perceived their roles and responsibilities of academic librarians to be classified into three dominant categories: research support, teaching, and managerial/administrative roles. Again, academic librarians were assigned to either the academic or pro fessional cadre in their universities based on the university’s understanding of the library as a professional or academic unit irrespective of the Librarian’s qualification, roles and responsibilities and the changing academic librarianship landscape. The study revealed the challenges librarians working in academic libraries face with their promotion and career progression, including long years of waiting (6 years) to qualify for the promotion, role inconsistencies, stagnation/lack of promotion, the presence of an unclear career path, and the inability to meet promotion requirements due to the lack of time for research, all of which have implications on their job satisfaction leading to demotivation and stress among academic librarians. The findings of this study have practical implications for policymakers in the Library and Information Science (LIS) field, Higher Education Institutions (HEI), and researchers to understand the perception of the roles, status, and career progression of the librarians working in academic libraries in Ghana and to inform policy decisions.

Total coliforms, arsenic and cadmium exposure through drinking water in the Western Region of Ghana: application of multivariate statistical technique to groundwater quality

In recent times, surface water resource in the Western Region of Ghana has been found to be inadequate in supply and polluted by various anthropogenic activities. As a result of these problems, the demand for groundwater by the human populations in the peri-urban communities for domestic, municipal and irrigation purposes has increased without prior knowledge of its water quality. Water samples were collected from 14 public hand-dug wells during the rainy season in 2013 and investigated for total coliforms, Escherichia coli, mercury (Hg), arsenic (As), cadmium (Cd) and physicochemical parameters. Multivariate statistical analysis of the dataset and a linear stoichiometric plot of major ions were applied to group the water samples and to identify the main factors and sources of contamination. Hierarchal cluster analysis revealed four clusters from the hydrochemical variables (R-mode) and three clusters in the case of water samples (Q-mode) after z score standardization. Principal component analysis after a varimax rotation of the dataset indicated that the four factors extracted explained 93.3 % of the total variance, which highlighted salinity, toxic elements and hardness pollution as the dominant factors affecting groundwater quality. Cation exchange, mineral dissolution and silicate weathering influenced groundwater quality. The ranking order of major ions was Na+ &gt; Ca2+ &gt; K+ &gt; Mg2+ and Cl− &gt; SO4 2− &gt; HCO3 −. Based on piper plot and the hydrogeology of the study area, sodium chloride (86 %), sodium hydrogen carbonate and sodium carbonate (14 %) water types were identified. Although E. coli were absent in the water samples, 36 % of the wells contained total coliforms (Enterobacter species) which exceeded the WHO guidelines limit of zero colony-forming unit (CFU)/100 mL of drinking water. With the exception of Hg, the concentration of As and Cd in 79 and 43 % of the water samples exceeded the WHO guideline limits of 10 and 3 μg/L for drinking water, respectively. Reported values in some areas in Nigeria, Malaysia and USA indicated that the maximum concentration of Cd was low and As was high in this study. Health risk assessment of Cd, As and Hg based on average daily dose, hazard quotient and cancer risk was determined. In conclusion, multiple natural processes and anthropogenic activities from non-point sources contributed significantly to groundwater salinization, hardness, toxic element and microbiological contamination of the study area. The outcome of this study can be used as a baseline data to prioritize areas for future sustainable development of public wells. © 2015, Springer International Publishing Switzerland.
