Heavy metal concentrations in fish tissues from Gilgel Gibe (I) Hydroelectric Dam Reservoir, Ethiopia

In this study, the concentrations of selected heavy metals including Cr, Co, Cu, Cd, and Pb were determined in gills, livers, and muscles of two fish species: Orochromis niloticus and Labeoberbus infermedius. The fish samples were collected from Gilgel Gibe I hydroelectric dam reservoir in may 2017. Prior to their quantitative determinations by flame atomic absorption spectroscopy, tissue samples were digested by a microwave digestion. Except, Cr (in gills) and Cd (in muscles), the target metals were detected in the gills, livers and muscles of both fish species and showed varied distributions among the tissues. But, the two species were nearly exhibited similar accumulation orders for the studied heavy metals. The order of concentrations of the metals in gill, liver and muscle of Labeoberbus infermedius were: Cu > Pb > Co > Cd; Cr > Cu > Pb > Co > Cd; and Cr > Pb > Cu > Co, respectively and while, in gill, liver and muscle of Orochromis niloticus were: Cu > Co > Pb > Cd; Cr > Cu > Co > Pb > Cd; and Cr > Pb > Cu > Co, respectively. The highest concentrations of Cr and Co were determined in livers; Cd was detected in the gills of both species; Cu was obtained in the liver of Labeoberbus infermedius and in the gill of Orochromis niloticus. Significant differences were observed among the mean concentrations of the metals in the fish tissues (p < 0.05). The concentrations Cr, Co, and Pb were higher than the maximum permissible limits recommended by FAO/WHO and EU. The concentration of Cu was below the maximum permissible limit of FAO/WHO, but above that of EU.Keywords: Gilgel Gibe I hydroelectric Dam; Orochromis niloticusor; Labeoberbus infermedius; Heavy metal

MyVoice Pulse Survey of WSU Staff: Working Through the COVID-19 Pandemic

The COVID-19 pandemic profoundly affected both staff and students in higher education institutions globally, with teaching and learning moving online, and research being suspended or adapted via videotelephony. Western Sydney University (WSU) surveyed its staff to develop a comprehensive understanding of the reported impacts of COVID-19 on both their work and life, and the strengths and challenges of utilising videotelephony for teaching and research. All WSU staff were surveyed via the MyVoice Pulse survey, with data collected by The Voice Project. A total of 2335 staff completed the survey, with a response rate of 86%. Permission was secured from 1695 (62.4%) staff for their responses to be included in this research. Out of these respondents, 59.6% identified as female, and 33.1% identified themselves as academic staff. Diversity related questions had Cronbach’s alpha of 0.63. All other questions when tested returned a Cronbach’s alpha of greater than 0.75 implying those questions were consistent. The current study provides valuable insight into the reported impacts of COVID-19 on the work and life of staff at WSU, as well as staff perspectives on some of the innovative practices that were adopted in response. The timeliness and the potential impact for informing University policy and practice are among the strengths of the study. The crosssectional nature of the data means that clear temporal associations between demographic factors and outcomes cannot be established. Additionally, it is important to note that results may be impacted by the uneven sample size in some groups. As COVID-19 transformed the work of the University and its staff dramatically, it appears that staff beliefs about the impacts of these changes varies substantially. If innovative practices such as remote teaching and HDR supervision, and videotelephony for research continue it will be important to conduct further research to identify exemplary practice given the current divide in staff opinion. Similarly, findings may serve as a catalyst for policies and practices that seek to address some of the inequities highlighted in staff voices

Breastfeeding in the community : how can partners/fathers help? : a systematic review

Support from partners/fathers and families can play a significant role in a mother’s decision to initiate, continue or cease breastfeeding postnatally. This study systematically reviewed published studies to determine the impact of specific types of partner support on breastfeeding initiation, duration and exclusivity. We used the 2015 Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines for the review. Seven computerized bibliographic databases (Embase, ProQuest Central, Scopus, PsycINFO, Web of Science, MEDLINE/PubMed and CINAHL) were searched. Of a total of 695 articles retrieved from the databases, seven studies met the inclusion criteria and reported on breastfeeding initiation, duration and exclusivity. Four of the seven studies found that partner support in the form of verbal encouragement to new mothers increased breastfeeding duration and exclusivity. Other types of partner supportive actions that led to improved breastfeeding behavior included sensitivity of the partner to the nursing mother’s needs, assistance in preventing and managing breastfeeding difficulties, and helping with household and child care duties. This review showed that specific supportive actions of partners/fathers in the community positively improved breastfeeding practices. To maximise the impact of breastfeeding policies and interventions among new mothers, breastfeeding programmes should consider the involvement of partners/fathers and their specific roles

Association of citrulline concentration at birth with lower respiratory tract infection in infancy: Findings from a multi-site birth cohort study

Assessing the association of the newborn metabolic state with severity of subsequent respiratory tract infection may provide important insights on infection pathogenesis. In this multi-site birth cohort study, we identified newborn metabolites associated with lower respiratory tract infection (LRTI) in the first year of life in a discovery cohort and assessed for replication in two independent cohorts. Increased citrulline concentration was associated with decreased odds of LRTI (discovery cohort: aOR 0.83 [95% CI 0.70-0.99], p = 0.04; replication cohorts: aOR 0.58 [95% CI 0.28-1.22], p = 0.15). While our findings require further replication and investigation of mechanisms of action, they identify a novel target for LRTI prevention and treatment

Business Registration and Firm Performance: Some Lessons From India

The aim of this paper is to evaluate the impacts on future firm performance of a firm deciding to register from the outset of its operations. Until now, the assumption has been that starting up registered is linked to higher future firm performance. Reporting World Bank Enterprise Survey (WBES) data collected in 2014 on 9,281 formal enterprises in India, and controlling for other determinants of firm performance as well as the endogeneity of the registration decision, the finding is that formal enterprises that start up unregistered and spend longer unregistered have significantly higher subsequent annual sales and employment growth rates compared with those registered from the outset. When the number of years spent unregistered is included, there are also productivity gains from delaying registration. The tentative explanation is that in this weak institutional environment, the advantages of registering from the outset are outweighed by the benefits of deferring registration. Evaluating the policy implications, the argument is that there is a need to shift away from the conventional eradication approach toward unregistered startups based on the assumption they are unproductive, and toward a more facilitating approach that improves the benefits of being registered and tackles the systemic formal institutional deficiencies that lead entrepreneurs to delay their decision to register

Factors associated with inadequate receipt of components and non-use of antenatal care services in India : a regional analysis

Background: Failure to use antenatal care (ANC) and inadequate receipt of components of ANC pose a significant risk for the pregnant woman and the baby. This study aimed to examine a regional analysis of factors associated with receiving no ANC and inadequate receipt of components of ANC services among Indian women. Method: Information from 173,970 women of reproductive age 15–49 years from the 2019–21 India National Family Health Survey (NFSH-5) was analysed. Logistic regression analyses that adjusted for cluster and survey weights were conducted to assess the socio-demographic and other factors associated with receiving non-use of ANC and inadequate receipt of components of ANC, respectively, in the six regions and 28 states, and 8 union territories in India. Results: Across regions in India, 7% of women reported no ANC, and the prevalence of inadequate and adequate receipt of components of ANC in all six regions ranged from 67 to 89% and 8% to 24%, respectively. Of all the 36 federated entities, the prevalence of inadequate receipt of ANC components was less than two-thirds in Tamil Nadu, Puducherry, Andaman and the Nicobar Islands, Odisha, and Gujarat. Our analyses revealed that associated factors vary by region, state, and union territories. Women from poor households reported increased odds of receiving no ANC in North, East and North-eastern regions. Women who reported no schooling in South, East and Central regions were associated with increased odds of receiving no ANC. Women from poor households in Himachal Pradesh, Bihar, Uttar Pradesh, Nagaland, Manipur, Uttar Pradesh, and Madhya Pradesh states reported significantly higher odds of inadequate components ANC than women from rich households. The receipt of inadequate components of ANC was significantly higher among women who never read magazines in Delhi, Ladakh, Karnataka, Telangana, Jharkhand, Maharashtra, Uttar Pradesh, Chhattisgarh, Arunachal Pradesh, Manipur, and Mizoram states in India. Conclusion: A better understanding of the factors associated with and incorporating them into the short- and long-term intervention strategies, including free financial support from the Indian government to encourage pregnant women from lower socioeconomic groups to use health services across all regions, states and union territories

Regional analysis of associations between infant and young child feeding practices and diarrhoea in Indian children

Studies on the association between infant and young child feeding (IYCF) practices and diarrhoea across regional India are limited. Hence, we examined the association between IYCF practices and diarrhoea in regional India. A weighted sample of 90,596 (North = 11,200, South = 16,469, East = 23,317, West = 11,512, Central = 24,870 and North-East = 3228) from the 2015–2016 National Family Health Survey in India was examined, using multivariate logistic regressions that adjust for clustering and sampling weights. The IYCF indicators included early initiation of breastfeeding (EIBF), exclusive breastfeeding (ExcBF), predominant breastfeeding (PBF), bottle feeding (BotF), continued breastfeeding (BF) at one-year, continued BF at two years, children ever breastfed and the introduction of solid, semi-solid or soft foods (ISSSF). Diarrhoea prevalence was lower among infants who were BF within one-hour of birth and those who were exclusively breastfed. Multivariate analyses revealed that continued BF at one and two years, and infants who were introduced to complementary foods had a higher prevalence of diarrhoea. EIBF and ExcBF were protective against diarrhoea in the regions of North, East and Central India. PBF, BotF and ISSSF were risk factors for diarrhoea in Central India. Continued BF at two years was a risk factor for diarrhoea in Western India. Findings suggested that EIBF and ExcBF were protective against diarrhoea in Northern, Eastern and Central India, while PBF, BotF, continued BF at two years and ISSSF were risk factors for diarrhoea in various regions in India. Improvements in IYCF practices are likely to reduce the burden of diarrhoea-related morbidity and mortality across regions in India

Infant and young child feeding practices among adolescent mothers and associated factors in India

Adequate infant and young child feeding (IYCF) improve child survival and growth. Globally, about 18 million babies are born to mothers aged 18 years or less and have a higher likelihood of adverse birth outcomes in India due to insufficient knowledge of child growth. This paper examined factors associated with IYCF practices among adolescent Indian mothers. This cross-sectional study extracted data on 5148 children aged 0–23 months from the 2015–2016 India National Family Health Survey. Survey logistic regression was used to assess factors associated with IYCF among adolescent mothers. Prevalence of exclusive breastfeeding, early initiation of breastfeeding, timely introduction of complementary feeding, minimum dietary diversity, minimum meal frequency, and minimum acceptable diet rates were: 58.7%, 43.8%, 43.3%, 16.6%, 27.4% and 6.8%, respectively. Maternal education, mode of delivery, frequency of antenatal care (ANC) clinic visits, geographical region, child’s age, and household wealth were the main factors associated with breastfeeding practices while maternal education, maternal marital status, child’s age, frequency of ANC clinic visits, geographical region, and household wealth were factors associated with complementary feeding practices. IYCF practices among adolescent mothers are suboptimal except for breastfeeding. Health and nutritional support interventions should address the factors for these indicators among adolescent mothers in India

Exclusive breastfeeding rates and associated factors in 13 "Economic Community of West African States" (ECOWAS) countries

Exclusive breastfeeding (EBF) has important protective effects on child survival and also increases the growth and development of infants. This paper examined EBF rates and associated factors in 13 “Economic Community of West African States” (ECOWAS) countries. A weighted sample of 19,735 infants from the recent Demographic and Health Survey dataset in ECOWAS countries for the period of 2010–2018 was used. Survey logistic regression analyses that adjusted for clustering and sampling weights were used to determine the factors associated with EBF. In ECOWAS countries, EBF rates for infants 6 months or younger ranged from 13.0% in Côte d’Ivoire to 58.0% in Togo. EBF decreased significantly by 33% as the infant age (in months) increased. Multivariate analyses revealed that mothers with at least primary education, older mothers (35–49 years), and those who lived in rural areas were significantly more likely to engage in EBF. Mothers who made four or more antenatal visits (ANC) were significantly more likely to exclusively breastfeed their babies compared to those who had no ANC visits. Our study shows that EBF rates are still suboptimal in most ECOWAS countries. EBF policy interventions in ECOWAS countries should target mothers with no schooling and those who do not attend ANC. Higher rates of EBF are likely to decrease the burden of infant morbidity and mortality in ECOWAS countries due to non-exposure to contaminated water or other liquids

Expansion of Agriculture in Northern Cold-Climate Regions: A Cross-Sectoral Perspective on Opportunities and Challenges

Agriculture in the boreal and Arctic regions is perceived as marginal, low intensity and inadequate to satisfy the needs of local communities, but another perspective is that northern agriculture has untapped potential to increase the local supply of food and even contribute to the global food system. Policies across northern jurisdictions target the expansion and intensification of agriculture, contextualized for the diverse social settings and market foci in the north. However, the rapid pace of climate change means that traditional methods of adapting cropping systems and developing infrastructure and regulations for this region cannot keep up with climate change impacts. Moreover, the anticipated conversion of northern cold-climate natural lands to agriculture risks a loss of up to 76% of the carbon stored in vegetation and soils, leading to further environmental impacts. The sustainable development of northern agriculture requires local solutions supported by locally relevant policies. There is an obvious need for the rapid development of a transdisciplinary, cross-jurisdictional, long-term knowledge development, and dissemination program to best serve food needs and an agricultural economy in the boreal and Arctic regions while minimizing the risks to global climate, northern ecosystems and communities
