The anti-money laundering law in Tanzania: whither the ongoing “war” against economic crimes?
Authors: Mniwasa Eugene E. 
Published: December 2020

PurposeThis paper aims to explore the evolution of the law for combating economic crimes including money laundering in Tanzania and explore the current developments in the anti-money laundering (AML) law and the ongoing fight against these crimes in Tanzania.Design/methodology/approachA desk-based review of documents on money laundering and its control in Tanzania was conducted. The paper presents qualitative data from the documentary sources. It applies the doctrinal legal research approach to examine, analyze and describe the AML law applicable in Tanzania. The paper uses the “law-in-context” research approach to explore some non-law aspects of money laundering in Tanzania and interrogate how the law addresses non-law dimensions of money laundering. Policy documents and media reports were analyzed. The thematic data analysis technique was applied, which involved identifying, describing and reporting issues according to the themes emerging from the data.FindingsThe AML law in Tanzania emerged from the law that was originally enacted to curb economic crimes. The law has evolved for some decades. Its evolution has been driven by domestic factors and foreign drivers which are political, economic and social in nature. The role of the AML law has been changing. Initially, the law was a tool for curbing economic crimes. Recently, the law has acquired a new role, namely, to facilitate the recovery of illicit funds and non-financial assets from offenders and enable the authorities in Tanzania to use those economic resources for developmental purposes.Research limitations/implicationsThe paper underscores the need for the Government of Tanzania to re-consider the broader implications involved in its current efforts to tackle economic crimes and money laundering. The balance between the implementation of the measures to combat money laundering and economic crimes in Tanzania and the importance of protecting rights of persons indicted with those offences should be struck. The AML law should be applied in such a way not to infringe the rights of the accused persons and not to throttle economic activities including the flow of legitimate foreign investments into Tanzania.Originality/valueThis paper generates insightful information to policymakers, law enforcers, regulators and other stakeholders who undertake activities to tackle money laundering and its control in Tanzania and researchers who study these issues for purposes of providing understanding of the problem and facilitating policy and legal reforms. The paper raises issues that can be explored further in future and contribute to the discourse on money laundering and its control in Tanzania.

Purpose
The quality of lost foam casted engineering components is directly influenced by the characteristics of the respective ceramic shell mold (CSM) and hence casting pattern. In this present work, rapid prototyping (RP) was used to fabricate the lattice structured patterns (LSPs) to reduce the defects and cracks in CSM during the heating stage.

Design/methodology/approach
The quality of the LSPs was accessed by measuring the dimensional accuracy. Further, the thermal stress in the CSM during the heating of porosity varied LSPs was analyzed using ANSYS software package 16.0. The Ni-alloy casting was fabricated by using the designed LSP and compared with its respective CAD model to access its quality.

Findings
The obtained results revealed that the Wigner–Seitz LSPs retained high accuracy and minimized the stress for defect-free CSM. Also, the thermal stress generated in the CSM depends upon the porosity coefficient of the LSP. Hence the interplay with porosity coefficient of LSPs leads to the formation of defect free CSM and hence high quality casting.

Originality/value
RP was used to develop LSPs and investigated the dependency of unit cell parameters on the accuracy of the final casting.

Authors: Hulio Zahid Hussain 
Published: December 2020

PurposeThe objective of this paper to assess the wind energy potential of the Sujawal site for minimizing the dependence on fossil fuels.Design/methodology/approachThe site-specific wind shear coefficient and the turbulence model were investigated. The two-parameter, k and c, Weibull distribution function was used to analyze the wind speed of the Sujawal site. The standard deviation of the site was also assessed for a period of a year. Also, the coefficient of variation was carried out to determine the difference at each height. The wind power and energy densities were assessed for a period of a year. The economic assessment of energy/kWh was investigated for selection of appropriate wind turbine.FindingsThe mean wind shear of the Sujawal site was found to be 0.274. The mean wind speed was found to be 7.458, 6.911, 6.438 and 5.347 at 80, 60, 40 and 20 m, respectively, above the ground level (AGL). The mean values of k parameter were observed to be 2.302, 2.767, 3.026 and 3.105 at 20, 40, 60 and 80 m, respectively, for a period of a year. The Weibull c m/s parameter values were found to be 8.415, 7.797, 7.265 and 6.084 m/s at 80, 60, 40 and 20 m, respectively. The mean values of standard deviation were found to be 0.765, 0.737, 0.681 and 0.650 at 20, 40, 60, and 80 m, respectively. The mean wind power density (W/m2) was found to be 287.33, 357.16, 405.16 and 659.58 for 20, 40, 60 and 80 m, respectively. The economic assessment showed that wind turbine 7 had the minimum cost/kWh US$ 0.0298.Originality/valueThe Sujawal site is suitable for installing the utility wind turbines for energy generation at the lowest cost; hence, a sustainable solution.
Predator control may not increase ungulate populations in the future: A formal meta‐analysis
Authors: Clark T. J. , Hebblewhite Mark 
Published: December 2020

Abstract

Human‐dominated landscapes are being recolonized by large carnivores, thereby increasing conflicts worldwide via predation of livestock and harvested wildlife such as ungulates. Recent meta‐analyses have shown that predator control (hereafter, predator removal) has mixed success in reducing livestock predation. Yet, it is unknown how effective predator removal is in decreasing predation on ungulates due to a lack of quantitative synthesis, despite the long history of implementation in North America.

We quantified the demographic responses of ungulate survival and recruitment rates, abundance, and population growth to experimental predator removal and identified the ecological and experimental design factors affecting ungulate responses to predator removal. We conducted a literature review of management and natural experiments to increase ungulate demography finding 52 predator removal experiments and 10 natural experiments from 47 publications. We then conducted a meta‐analysis to determine the overall effect size and factors which increased ungulate demography during predator removal. Lastly, we tested for evidence of publication bias and experimental rigour for these experiments.

We found that predator removal in both management and natural experiments increased ungulate demographic responses by 13% (95% CI = 4.1%–23%), yet prediction intervals overlapped with 0 (95% PI = −34% to 93%). Focusing just on management removals, ungulate demographic responses increased only by 7.8% (95% PI = −32% to 72%), indicating that future experiments could have negligible effects. Predator removal in both management and natural experiments was more successful in improving the demography of young (e.g. recruitment ES = 44%, 95% CI = 13%–83%) but equivocal in improving adult survival (ES = 5.4%, 95% CI = −18% to 36%) and ungulate abundance (ES = 13%, 95% CI = −17% to 31%). The low and variable effectiveness of predator removal for ungulate populations might be linked to ungulates' slow life history and the compensatory mortality of carnivores on ungulates, though effects were stronger on endangered prey.

We identified the experimental design factors that led to greater uncertainty in ungulate responses to predator removal, including lack of randomization, low replication and short temporal length. Lastly, we found evidence of publication bias, where experiments with poor rigour and negative effects (i.e. reduced ungulate demography following predator removal) were under‐reported.

Synthesis and Applications. We recommend future predator removal experiments be conducted with a more rigorous experimental design to overcome these weaknesses, especially for endangered species where predator removal may work more effectively. We suggest that managers attempting to evaluate experimental practices to increase ungulate populations through predator removal could employ an open standards framework akin to the ‘Open Standards for the Practice of Conservation’ framework.
Mosses reduce soil nitrogen availability in a subarctic birch forest via effects on soil thermal regime and sequestration of deposited nitrogen
Authors: Koranda Marianne , Michelsen Anders 
Published: December 2020

Abstract

In high‐latitude ecosystems bryophytes are important drivers of ecosystem functions. Alterations in abundance of mosses due to global change may thus strongly influence carbon (C) and nitrogen (N) cycling and hence cause feedback on climate. The effects of mosses on soil microbial activity are, however, still poorly understood. Our study aims at elucidating how and by which mechanisms bryophytes influence microbial decomposition processes of soil organic matter and thus soil nutrient availability.

We present results from a field experiment in a subarctic birch forest in northern Sweden, where we partly removed the moss cover and replaced it with an artificial soil cover for simulating moss effects on soil temperature and moisture. We combined this with a fertilization experiment with 15N‐labelled N for analysing the effects of moss N sequestration on soil processes.

Our results demonstrate the capacity of mosses to reduce soil N availability and retard N cycling. The comparison with artificial soil cover plots suggests that the effect of mosses on N cycling is linked to the thermal insulation capacity of mosses causing low average soil temperature in summer and strongly reduced soil temperature fluctuations, the latter also leading to a decreased frequency of freeze‐thaw events in autumn and spring. Our results also showed, however, that the negative temperature effect of mosses on soil microbial activity was in part compensated by stimulatory effects of the moss layer, possibly linked to leaching of labile substrates from the moss. Furthermore, our results revealed that bryophytes efficiently sequester added N from wet deposition and thus prevent effects of increased atmospheric N deposition on soil N availability and soil processes.

Synthesis. Our study emphasizes the important role of mosses in carbon and nutrient cycling in high‐latitude ecosystems and the potential strong impacts of reductions in moss abundance on microbial decomposition processes and nutrient availability in subarctic and boreal forests.

SummarySoil aggregates, with complex spatial and nutritional heterogeneity, are clearly important for regulating microbial community ecology and biogeochemistry in soils. However, how the taxonomic composition and functional attributes of N‐cycling‐microbes within different soil particle‐size fractions under a long‐term fertilization treatment remains largely unknown. Here, we examined the composition and metabolic potential for urease activity, nitrification, N2O production and reduction of the microbial communities attached to different sized soil particles (2000–250, 250–53 and <53 μm) using a functional gene microarray (GeoChip) and functional assays. We found that urease activity and nitrification were higher in <53 μm fractions, whereas N2O production and reduction rates were greater in 2000–250 and 250–53 μm across different fertilizer regimes. The abundance of key N‐cycling genes involved in anammox, ammonification, assimilatory and dissimilatory N reduction, denitrification, nitrification and N2‐fixation detected by GeoChip increased as soil aggregate size decreased; and the particular key genes abundance (e.g., ureC, amoA, narG, nirS/K) and their corresponding activity were uncoupled. Aggregate fraction exerted significant impacts on N‐cycling microbial taxonomic composition, which was significantly shaped by soil nutrition. Taken together, these findings indicate the important roles of soil aggregates in differentiating N‐cycling metabolic potential and taxonomic composition, and provide empirical evidence that nitrogen metabolism potential and community are uncoupled due to aggregate heterogeneity.

AbstractFalls are a traumatic event that represents a major public health problem worldwide. The literature is rich in published studies of falls from heights, but only a few articles have focused on falls into wells. The region of Kairouan, in central Tunisia, is characterized by an arid climate, hence the abundance of wells for watering crops. In this study, 72 cases of deadly falls into wells were retrospectively investigated at the Department of Forensic Medicine in Kairouan over eight years (01/01/2008 to 31/12/2015). A male predominance was found (sex ratio of 2.42), with a mean age of 29 ± 16.1 years. Sixty‐five cases (90.3%) were from rural areas, 62.5% had a low level of education, and 50% were unemployed. In our series, the deceased fell from a distance between 3 and 70 meters with an average of 28.3 m. The falls occurred into functional wells in 61.1%, which were filled with water in 51.4%, and were unprotected in 88.9%. Autopsy findings showed bone fractures in 51.4% of cases of which 44.4% were rib fractures. Visceral injuries were identified in 55.6% of cases. The predominant manner of death was suicide (73.2%), and severe polytrauma was the most frequent cause of death (52.8%). This study highlights the need for increased safety measures to keep wells covered and protected in order to prevent these falls.

AbstractAimIn Australian adults, this study seeks to describe the experiences and factors associated with the perceived outcomes of using a very low calorie diet (VLCD) program for ≥4 weeks.MethodsA mixed method study using the method perspective was conducted to analyse individual semi‐structured interviews conducted via videoconference and cross‐sectional survey data. Australians 18 to 65 years were eligible if they were currently consuming at least one VLCD product daily for ≥4 weeks or had ceased consumption within 4 weeks. Interviews were thematically analysed.ResultsWeight loss (19 kg [SD: 18 kg]) and duration (5 months [SD: 5 months]) of VLCD product use of the 31 participants (female: 97%, 44 [SD: 11] years, body mass index >30 kg/m2: 84%) were strongly correlated (r= 0.73,P < .001). Participants' experiences were influenced by a journey of learning from their previous weight loss attempts, discerned the VLCD program as credible, and chose to commence the VLCD due to a convergence of internal motivators. Early health‐related outcomes were a reinforcing stimulus and participants developed new health behaviours but felt dependent on the VLCD long term. Throughout these experiences the participants identified various individual, program structure, and environment related factors which either facilitated their VLCD program use or created barriers to achieving their goals. Health care professionals were minimally engaged.ConclusionsA model of care to support facilitators and overcome barriers would mean more meaningful engagement of health care professionals to ultimately improve the experience and adherence of the VLCD program users in Australia.
Associations between breakfast consumption from childhood to adulthood and cardiometabolic health: A systematic review

Published: December 2020

AbstractAimBreakfast consumption may be associated favourably with cardiometabolic health. Most studies only measure breakfast consumption at one timepoint, whereas repeated measures allow for associations to be explored from a life course perspective. This systematic review assessed evidence from cohort studies on associations between breakfast consumption from childhood to adulthood and cardiometabolic health.MethodsSeven databases were searched; eligible records included analyses assessing breakfast consumption in childhood and adulthood, and type 2 diabetes, cardiovascular disease, obesity or associated clinical risk factors. Risk of bias was assessed using the Joanna Briggs Institute checklist for cohort studies.ResultsSix eligible articles were reviewed, representing four cohort studies from two countries. Body composition was the only outcome investigated by five articles; the sixth article investigated body composition as well as a metabolic syndrome score and serum cardiometabolic risk markers. Most articles found significant associations between breakfast consumption in childhood and adulthood and cardiometabolic benefits, however the quality of evidence was poor. Childhood and adulthood breakfast consumption were each associated with cardiometabolic benefits, and breakfast consumption over both life stages was associated with greater benefits. An increase in breakfast consumption from childhood to adulthood was also associated with cardiometabolic benefits.ConclusionsWe evaluated the available literature and found limited studies of low quality to suggest that more frequent breakfast consumption across both childhood and adulthood may be associated with the greatest cardiometabolic benefits. Further research is needed to develop an understanding of the relationship between breakfast and cardiometabolic health from a cross‐lifestage perspective.

AbstractAimThis study examined factors associated with severity, incidence and/or persistence of internet gaming disorder (IGD) in children and adolescents.Design, Setting, ParticipantsProspective cohort study with 2‐year follow‐up study in South Korea. A total of 2319 3rd‐, 4th‐ and 7th‐graders enrolled into the internet user cohort for unbiased recognition of gaming disorder in early adolescence [intramural Continuing Umbrella of Research Experiences (iCURE)] and analyzed for the current study.MeasurementsSeverity of the IGD features was assessed by the Internet Game Use‐Elicited Symptom Screen (IGUESS), a self‐reported questionnaire based on the DSM‐5 IGD criteria. Participants with IGUESS scores ≥ 10 were considered to be at high risk for IGD (HIGD). Time spent playing on‐line games, game types, depressive symptoms, trait anxiety, attention deficit hyperactivity disorder (ADHD) symptoms, social support, openness of communication with parents, attachment to parents and potential confounders were assessed by self‐report.FindingsA total of 175 (7.5%) students were classified as HIGD cases upon initial assessment. The independent risk factors of incidence of HIGD included playing on‐line games for ≥ 240 minutes/day, playing multi‐player games, depressive symptoms and ADHD symptoms [adjusted rate ratios (aRRs) = 2.03, 1.63, 2.04, 2.53, respectively; all P < 0.05]. Factors related to changing IGD severity scores were playing on‐line games for 60–239 minutes/day, playing single‐player on‐line games, higher attachment and social support [adjusted incidence rate ratio (aIRRs) = 1.38, 1.22, 0.86, 0.87, respectively; all P < 0.05]. Independent predictors of persistence of HIGD were playing on‐line games for ≥ 240 minutes/day and ADHD symptoms (aRRs = 2.63, 2.14, respectively; all P < 0.05).ConclusionsAmong adolescents in South Korea, the existence of ADHD symptoms and spending more than 4 hours per day playing on‐line games were associated with the occurrence or persistence of high risk for internet gaming disorder.
