Published: December 2020

Se indaga sobre la relación que existe entre el bienestar psicológico y la autoeficacia en una muestra de 153 universitarios migrantes de Lima Metropolitana, con una edad promedio de 21,43 años (D.E.= 2.12), de los cuales el 62% fueron mujeres y el 38% varones de universidades privadas de Lima. Se emplearon como instrumento de medida, la escala de bienestar psicológico, adaptada al contexto peruano por Domínguez (2014) y la escala de autoeficacia General empleada por Terry (2008). Los resultados muestran una correlación positiva entre la autoeficacia y las variables de aceptación y control (r = .295, p< .01) y autonomía (r = .411, p< .01). Además, se muestran diferencias estadísticamente significativas al comparar el bienestar psicológico entre quienes tienen y no pareja; mientras que se observan estadísticamente significativas al comparar la autoeficacia en función a tener o no pareja, género y edad. Se concluye que algunas dimensiones del bienestar psicológico se relacionan con la autoeficacia; además se observan diferencias significativas al comparar ambas variables entre otras de tipo sociodemográfico.

Concluyendo que existe una relación mínima entre variables.
Nested Theories of Change for Adaptive Rigour
Authors:   Institute of Development Studies, Higdon Grace Lyn
Published: December 2020

This learning brief provides illustrative examples of three major adaptations the Coalition for Religious Equality and Inclusive Development (CREID) programme has undertaken while working within fragile contexts to promote freedom of religion or beilief (FoRB). These examples highlight how the programme has utilised embedded monitoring, evaluation, and learning (MEL) strategies to encourage what Ramalingam et al. (2019) refer to as ‘adaptive rigour’, a concept which underscores the importance of transparent documentation of programmatic decision making processes during programme adaptations. In particular this learning brief discusses the use of nested theories of change as a mechanism to enable adaptive rigour within the 'multitude of smalls' approach in the CREID programme.
How to Talk About Incontinence: A Checklist
Authors: Rosato-Scott Claire , Barrington Dani J. , Bhakta Amita , House Sarah J. , Mactaggart Islay , Jane Wilbur
Published: December 2020

Incontinence is the medical term used to describe the involuntary loss of urine or faeces. Women, men, girls, boys and people of all genders, at any age, can experience incontinence. A person with incontinence can experience leakage occasionally, regularly or constantly; and leakage can happen at any time, day or night. A person may also experience leakage of urinary or faecal matter due to not being able to get to the toilet in time or not wanting to use the toilet facilities available. This is known as social, or functional, incontinence. In many low- and middle-income countries (LMICs) understanding of incontinence is still in its early stages: the term ‘incontinence’ may not be known, knowledge of the condition is rare, and the provision of support is lacking. Those who experience incontinence may face stigma due to having the condition, and this may affect their willingness or confidence to talk about it. There is a need to better understand incontinence in LMICs, and how best to support people living with the condition to improve their quality of life. This requires having conversations with individuals that experience the condition, and with individuals who care for those who do: they will have the lived experiences of what it means to live with incontinence practically, emotionally and socially for them and their families. Living with incontinence can have a range of impacts on the people living with it and their carers. These include increased stress and distress; additional needs for water and soap; and restricted ability to join in community activities, school or work. Living with incontinence can also lead to a range of protection issues. The potential challenges that people face may be quite diverse and may vary between people and households. The checklist below, and corresponding page references to ‘Incontinence: We Need to Talk About Leaks’ can be used to increase your understanding of incontinence and the options available to support people living with the condition; and provide guidance on how to have conversations to understand how best to support people living with incontinence in your area.

State social policy at the present stage of development of Russia
Authors: GERSONSKAYA Irina V.
Published: December 2020

The effectiveness of the state social policy largely determines the production of quality public goods by state structures, the improvement of the demographic situation, the comprehensive development of human capital, the improvement of social well-being and the socio-economic development of the country as a whole. Therefore, the purpose of the study is to reseasch the main directions of state social policy in Russia and assess the effectiveness of the social sector. The methodological basis of the study was the Keynesian concept of state regulation of the economy, since the state sets basic social standards, provides social protection for the population and social guarantees. We conducted the study using Rosstat data reflecting the main indicators of the social sphere of Russia. We determined the overall effectiveness of State social policy on the basis of changes in demographic processes, indicators of the living standards of the population, the volume of state social expenditures, the functioning of the education system, health care and social services. We studied the difficult demographic situation in Russia. We considered indicators of the living standards of the population and a decrease in their level, an increase in poverty and a significant social stratification in society; analyzed government spending on education, health and social policy; summarized the main problems in the educational sphere in the provision of medical services and in the process of state social services of the population; established that the functioning of the social sphere does not fully meet social needs, and the activities of the social sector of the state are ineffective. The proposed study of state social policy demonstrates its relevance to Russian society.

Život tranzitologije u Hrvatskoj politologiji

We show the enhancement in the intensity and emission rate of perovskite cesium lead bromide (CsPbBr3) and formamidinium lead bromide (FAPbBr3) nanocrystals in the presence of single and double gold layer cavities, which we refer to as Metal-Emitter (ME) and Metal-Emitter-Metal (MEM) nanostructures. Up to 1.9-fold photoluminescence intensity and up to 5.4-fold emission rate enhancements were obtained for FAPbBr3 nanocrystals confined by double gold layers, which are attributed to plasmonic confinement from the gold layers. The experimentally obtained values are validated by analytical calculations and electromagnetic simulations. Such an effective method of manipulation of the spontaneous emission rate by simple plasmonic nanostructures can be utilized in sensing and detection applications.
Intestinal Absorption of β-Glucans and Their Effect on the Immune System
Authors: Hino Shingo , Nishimura Naomichi , Matsuda Tsukasa , Morita Tatsuya
Published: December 2020

β-glucan is a generic term for insoluble dietary fibers exerting various effects on the immune system. As a group, β-glucans are non-cellulose polysaccharides composed of a glucopyranose as the main constituent sugar with β configuration, having a β- (1,3)-linked glucopyranose main chain as a common feature. β-glucans are absorbed through the intestine. Since the 1980s, there have been many studies reporting various effects of β-glucans on the immune system, including reports on receptors, that have slowly clarified their recognition system and action mechanisms. However, these studies focused mostly on treatments of infectious diseases and tumors; thus, the effects of β-glucans ingested in food as dietary fiber and their mechanisms of action remain largely unknown. The uptake of β-glucan into the body may be resemble that of proteins, which are soluble polymers, and insoluble material such as dietary fiber. Dietary fibers have varied structures, with wide-ranging solubility and physiological effects. Understanding whether these substances are actually taken up, how they exert their effects, and their metabolism after being taken up are important issues when considering the functionality and safety of dietary fibers.

Fear extinction requires coordinated neural activity within the amygdala and medial prefrontal cortex (mPFC). Any behavior has a transcriptomic signature that is modified by environmental experiences, and specific genes are involved in functional plasticity and synaptic wiring during fear extinction. Here, we investigated the effects of optogenetic manipulations of prelimbic (PrL) pyramidal neurons on amygdala gene expression to analyze the specific transcriptional pathways involved in adaptive and maladaptive fear extinction. To this aim, transgenic mice were (or not) fear-conditioned and during the extinction phase they received optogenetic (or sham) stimulations over PrL pyramidal neurons. At the end of behavioral testing, electrophysiological (neural cellular excitability and Excitatory Post-Synaptic Currents) and morphological (spinogenesis) correlates were evaluated in the PrL pyramidal neurons. Furthermore, transcriptomic cell-specific RNA-analyses (differential gene expression profiling and functional enrichment analyses) were performed in amygdala pyramidal neurons. Our results show that the optogenetic activation of PrL pyramidal neurons in fear-conditioned mice induces fear extinction deficits, reflected in an increase of cellular excitability, excitatory neurotransmission, and spinogenesis of PrL pyramidal neurons, and in strong modifications of the transcriptome of amygdala pyramidal neurons. Understanding the electrophysiological, morphological and transcriptomic architecture of fear extinction may facilitate the comprehension of fear-related disorders.
The Role of Community Radio for Integrated and Sustainable Development in Ethiopia: A Critical Review on the Holistic Approach
Authors: Bayable Destaw
Published: December 2020

Community radios play a paramount role in the development of the community. Community radio stations have been highly engaged in addressing social, economic, cultural, educational, health, environmental, sanitation, and disaster issues effectively and strategically using local languages in context. Community radios are also used to express, and share indigenous views, thoughts, ideas, problems, and perspectives of local people. The purpose of this analysis is to explore the role of community radio for integrated and sustainable development in Ethiopia. It used a systematic narrative review. Nine research works and five assessments report were selected purposively and analyzed in a quantitative approach. Currently, in Ethiopia, there are 50 community radio stations that received broadcast licenses from Ethiopian Broadcast Authority with four types of licensing and broadcasting in 29 local languages. Community radio helps the community to identify their common goals, create holistic plans, monitor the progress of their developmental activities, and guide on sustainable development. It contributes to integrated and sustainable development in a collaborative and creative process that cultivates the social, economic, and political conditions needed for the community to succeed which aimed to improve and sustain the livelihoods of the community. However, the media can’t achieve its target goal to support the development activities and bring holistic development of the community. As a result; this review paper focuses on reviewing how Ethiopians use community radios for holistic development. And it suggested the way how we can use community radios for the prospective holistic development in Ethiopia.

Published: December 2020

The transition from a dormant to a germinating seed represents a crucial developmental switch in the life cycle of a plant. Subsequent transition from a germinating seed to an autotrophic organism also requires a robust and multi-layered control. Seed germination and seedling growth are multistep processes, involving both internal and external signals, which lead to a fine-tuning control network.

Published: December 2020

Site Index has been widely used as an age normalised metric to account for variation in forest height at a range of spatial scales. Although previous research has used a range of modelling methods to describe regional variation in Site Index little research has examined gains that can be achieved through use of regression kriging or spatial ensemble methods. In this study an extensive set of environmental surfaces were used as covariates to predict Site Index measurements covering the environmental range of \textit{Pinus radiata} D. Don plantations in Chile. Using this dataset, the objectives of this research were to (i) compare predictive precision of a range of geostatistical, parametric and non-parametric models, (ii) determine if significant gains in precision can be attained through use of regression kriging, (iii) evaluate the precision of a spatial ensemble model that utilises predictions from the five most precise models, through using the model prediction with lowest error for a given pixel and (iv) produce a map of Site Index across the study area. The five most precise models were all geostatistical and included ordinary kriging and four regression kriging models that were based on partial least squares or random forests. A spatial ensemble model constructed from these five models was the most precise of those developed (RMSE = 1.851 m, RMSE% = 6.38%) and had relatively little bias. Climatic and edaphic variables were the strongest determinants of Site Index and in particular, variables related to soil water balance were well represented within the most precise predictive models. These results highlight the utility of predicting Site Index using a range of approaches, as these can be used to construct a spatial ensemble that may be more precise than predictions from the constituent models.

Proteasome inhibitors, like bortezomib, play a key role in the treatment of multiple myeloma (MM); however, most patients eventually relapse and eventually show multiple drug resistance, and the molecular mechanisms of this resistance remain unclear. The present study examines the expression of previously-described genes that may influence resistance to bortezomib treatment at the mRNA level (ABCB1, CXCR4, MAF, MARCKS, POMP, PSMB5, RPL5, TXN and XBP1). mRNA expression was determined in 73 MM patients treated with bortezomib-based regimens (30 bortzomib-sensitive and 43 bortezomib-refractory patients) and 11 healthy controls. RPL5 was significantly down-regulated in multiple myeloma patients as compared with healthy controls. Moreover, POMP was significantly up-regulated in MM patients refractory to bortezomib-based treatment. In multivariate analysis, high expression of PSMB5 and CXCR and autologous stem cell transplantation were independent predictors of progression-free survival, and high expression of POMP and RPL5 was associated with shorter overall survival.
Information Technology Impact Factor Model in Life Cycle Cost Management of Construction Project
Authors: Mésároš Peter , Mandičák Tomáš , Spišáková Marcela
Published: December 2020

Construction project management and cost management is a difficult process that affects the overall success of construction projects. The success of a construction project can be assessed according to key performance indicators (KPIs). Cost savings and cost optimization over the life of a construction project is one of these KPIs. Cost management is largely performed through intelligent information technology in the construction industry. Information systems and information technologies have seen an increase in use in the management of construction projects. The same goes for cost management. Several studies mentioned in the paper point to this increase in use in recent years also in the management of costs at various stages. Many studies point to the use of information technology and software applications in the field of cost management. Still, to a large extent, there are no surveys focused on the analysis of the impact and impact factor of information technology on cost savings or cost optimization in various phases of construction projects. The research discusses the issue of the impact of information technology on cost management in various phases of a construction project. The main goal of the research is to analyze the influence of information technology factors on cost savings and optimization in individual phases of a construction project. Several statistical methods were used in the research. The resulting model of information technology impact factor was created based on data processing and the use of the AHP method.
Understanding vocational students' motivation for dietary and physical activity behaviours
Authors: Kuipers Annabelle , Kloek Gitte Caroline , Vries Sanne Irene de
Published: December 2020

Unhealthy eating behaviors and low levels of physical activity are a major problem in adolescents and young adults in vocational education. To develop effective intervention programs, more research is needed to understand how different types of motivation contribute to health behaviors. In the present study the Self-Determination Theory is used to examine how motivation contributes to dietary and physical activity behaviors in vocational students. This cross-sectional study included 809 students (mean age 17.8 ± 1.9 years) attending vocational education in the Netherlands. Linear multilevel regression analyses were used to investigate the association between type of motivation and dietary and physical activity behaviors. Amotivation was negatively associated with breakfast frequency and was positively associated with diet soda consumption and high calorie between-meal snacks. A positive association was found between autonomous motivation and water intake, breakfast frequency, fruit intake and moderate-to-vigorous physical activity. Autonomous motivation was negatively associated with the consumption of unhealthy products. Controlled motivation was not associated with physical activity or dietary behaviors. Type of motivation seems to partly explain dietary and physical activity behaviors in vocational students. Autonomous motivation in particular was shown to be associated with healthy behaviors and could therefore be a valuable intervention target.
A hybrid cost-sensitive ensemble for heart disease prediction
Authors: Qi Zhenya , Zhang Zuoru
Published: December 2020

Background: Heart disease is the primary cause of morbidity and mortality in the world. It includes numerous problems and symptoms. The diagnosis of heart disease is difficult because there are too many factors to analyze. What's more, the misclassification cost could be very high. Methods: A cost-sensitive ensemble method was proposed to improve the efficiency of diagnosis and reduce the misclassification cost. The proposed method contains five heterogeneous classifiers: random forest, logistic regression, support vector machine, extreme learning machine and k-nearest neighbor. T-test was used to investigate if the performance of the ensemble was better than individual classifiers and the contribution of Relief algorithm. Results: The best performance was achieved by the proposed method according to ten-fold cross validation. The statistical tests demonstrated that the performance of the proposed ensemble was significantly superior to individual classifiers, and the efficiency of classification was distinctively improved by Relief algorithm. Conclusions: The proposed ensemble gained significantly better results compared with individual classifiers and previous studies, which implies that it can be used as a promising alternative tool in medical decision making for heart disease diagnosis.

We report a green carbon capture and conversion technology offering scalability and economic viability for mitigating CO2 emissions. The technology uses suspensions of gallium liquid metal to reduce CO2 into carbonaceous solid products and O2 at near room temperature. The nonpolar nature of the liquid gallium interface allows the solid products to instantaneously exfoliate, hence keeping active sites accessible. The solid co-contributor of silver-gallium rods ensures a cyclic sustainable process. The overall process relies on mechanical energy as the input, which drives nano dimensional triboelectrochemical reactions. By altering the secondary solvent and changing the reactor height, the dissolution and conversion efficiency can be tuned. The optimum reactor height is only 27 cm, when gallium/silver fluoride mix at 7:1 mass ratio is employed as the reaction material. At CO2 input of ~8 sccm, 92% efficiency was obtained at the record low input energy of 228.5 kW∙h for the capture and conversion of a tonne of CO2. The potential impact of this green technology is remarkable, likely benefiting a variety of industries and offering an economical solution for CO2 capture and conversion.

Published: December 2020

Although breast milk is the ideal food source for newborns during the first six months of life, a high percentage of children receive infant formulas. There is evidence that specific diet habits may influence individual metabolic profile. Therefore, in newborns, such profile can be influenced by the use of infantile formulas given the composition differences that display compared to human milk. Up to now there are no reports in the literature that address this issue. Thus, this work aims to compare the metabolic profile of full-term newborns that were feed with either breast milk (n=32) or infantile formulas (n=21). Metabolic profile was established based on urine analysis through gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (H-NMR). Results evidenced a more gluconeogenic profile in breast fed infants. In addition, infant formula fed infants presented urinary excretion of metabolites derived from specific compounds present in this type of diet that were not observed in breast fed infants. Finally, it was observed that in infant formula fed infants there was excretion of basal levels of metabolites of clinical relevance. This results show the importance of understanding the metabolic impact of diet in newborn population in normal and pathological contexts.
Markov jump transport of trapped charge in thin dielectric layers
Authors: Pil'nik Andrey , Chernov Andrey , Islamov Damir
Published: December 2020

In this study, we developed a discrete theory of the charge transport in thin dielectric films by trapped electrons or holes, that is applicable both for the case of countable and a large number of traps. It was shown that Shockley-Read-Hall-like transport equations, which describe 1D transport through dielectric layers, might incorrectly describe the charge flow through the ultra-thin layers with a countable number of traps, taking into account injection-from and extraction-to electrodes (contacts). A comparison with other theoretical models shows a good agreement. The developed model can be applied to one-, two- and three-dimensional systems. The model, formulated in a system of linear algebraic equations, can be implemented in the computational code using different optimized libraries. We demonstrated that analytical solutions can be found for stationary cases for any trap distribution and for dynamics of system evolution for special cases. These solutions can be used to test the code and for studying of charge transport properties of thin dielectric films.

Background: Transabdominal ultrasonography (TUS) is a non-invasive method that can be performed repeatedly. Although the usefulness of TUS in ulcerative colitis (UC) has been reported, no well-established data exist yet. This study aimed to determine the usefulness of TUS, compared with colonoscopy (CS), in detecting the presence of mucosal inflammation in each segment of the colon among patients with UC. Methods: Eighty UC patients who underwent US within 14 days after CS were retrospectively registered. We divided the colon into five segments and measured the bowel wall thickness (BWT) using TUS. The results were then compared with the Mayo endoscopic subscore classification (MES) in order to determine their accuracy.Result: We evaluated a total of 268 lesions for each segment among 80 UC patients. The proportion of BWT decreased with an increase in the MES of each segment (p < 0.0001, Cochran-Armitage trend test). The sensitivity, specificity, and accuracy of positive BMT (BWT >2 mm) for detecting mucosal inflammation (MES >0) of each segment were 0.85-1.00, 0.78-0.93, and 0.87-0.98, respectively. Conclusion: This study concluded that TUS was a useful method for detecting the presence or absence of inflammation sites among UC patients due to its high accuracy when BMT >2 mm was considered as a positive finding. This non-invasive method may help control the disease activity of UC.

Background: Cardiac resynchronization therapy via biventricular pacing is an established therapy for patients with heart failure. However, high nonresponder rates and inability to predict response remains a challenge. Recently left bundle branch area pacing (LBBAP) has been shown to be feasible and may also improve clinical outcomes. In this article we describe the new technique (sequential LBBAP followed by left ventricular pacing, LOT-CRT) and assess the feasibility of LOT-CRT.Methods: The RV implantation site was positioned and the LBBAP lead was implanted using our methods. The QRS duration (QRSd) at baseline, during LBBAP, biventricular pacing, and LOT-CRT was measured. Results: LOT-CRT was successful in 5 patients (age 71.8 ± 5.1 years, men 3, ischemic 3). The QRSd at baseline was 158.0 ± 13.0 ms and significantly narrowed to 117.0 ± 6.7 ms during LOT-CRT (P < 0.01). During 3-month follow-up, LV ejection fraction improved from 32.8 ± 5.2 % to 45.0 ± 5.1% (P < 0.01), and New York Heart Association functional class changed from 3.25 ± 0.5 to 2.5 ± 0.6 (P < 0.05). A decrease in left ventricular end-diastolic dimension was observed, with widening from (68.2 ± 12.3) mm at baseline to (62.2 ± 11.3) mm at pacing (P < 0.05). The length of operation time was (152.0 ± 31.1) min. Conclusions: The study demonstrates that LOT-CRT is clinically feasible in patients with systolic HF and LBBB. LOT-CRT was associated with significant narrowing of QRSd and improvement in LV function, especially in patients with ischemic cardiomyopathy.
Development of a Physicians’ Choice Model Using Mixed Logit With Random Prices for Drugs Case Study on Diabetes Type II
Authors: Huttin Christine Claude , Hausman Jerry
Published: December 2020

This paper presents a first experiment with random generator of drug prices and a first simulation on physicians’ treatment choices (case on pharmacotherapies) for diabetes type II care. It also aims to compare the effects of the price variables according to public versus private health plans on physicians’ choices (Medicare versus commercial Health Plans). The base line model used is a Mixed Logit model with Random Price variables. A series of experiments with random parameters generations is designed with various sequences and number of draws. The model is tested on a real analytical dataset, extracted from the CDC physician survey (National Ambulatory Care Survey, NAMCS), for patients with diabetes type II without complications, for previous predictive econometrics with ENDEPUSresearch, Inc. The model uses a first drug choice set with three alternatives: oral agents only, combined therapies, no drug. The choice models introduce qualitative dependent variables and complement the series of cumulative logistic models per disease. The matlab code for the new specification test on the Independence of Irrelevant Alternatives at individual level is modified to fit this type of medical applications; first runs compare main parameters of a full choice set versus reduced choice sets of alternatives. It is planned to design more experiments for extended choice sets and widespread applications, in order to lead to user friendly tools for medical systems. The collaboration with Professor Jerry Hausman on the US market will help with use of results and new ways to adjust the reliability on the selection of alternatives; it may provide additional guidance to the algorithms used by professionals and for health policies.

Background and objective: Myocardial infarction is the number one cause of death both in males and females in many developed countries. Citrullus colocynthis is a medicinal plant used for the treatment for asthma, constipation, cough. The current study evaluates the cardioprotective potential of hydroalcoholic peel extract of Citrullus colocynthis against adrenaline-induced myocardial infarction in rabbits.Materials and Methods: Animals were divided into four major groups each group consisting of six rabbits. Group - 1 was given adrenaline 2mg/kg subcutaneously for two successive days. Considerably (p<0.001) accelerated the ALP, AST, ALT, Troponin, CK-MB, LDH, and CRP (p<0.05). Group 2, 3, 4 rabbits pre-treated with the peel extract of C. colocynthis 100mg/kg, 200mg/kg, 300mg/kg respectively orally for 14 successive days and on 14th and 15th-day adrenaline was inoculated considerably improve the impact of adrenaline through lowering the levels of CK-MB, LDH, Troponin, AST, CRP, ALT, and ALP.Results: The myocardial tissues of adrenaline induced group have more necrotic lesions. A slight deteriorating modifications of myocardial tissues usually in cardiac cells structure were observed in the group treated with extract.Conclusion: The out-turn showed the cardioprotective potential of hydroalcoholic peel extract of C. colocynthis in a dose-dependent manner.
Testing the Environmental Kuznets Curve Hypothesis for Turkey: The Role of Clean Energy Consumption and Ecological Footprint
Authors: Yurtkuran Suleyman
Published: December 2020

This study aims to investigate the dynamic relationship between income, clean energy consumption, exports, imports, urbanization and ecological footprint for Turkey from 1973 to 2015 using the environmental Kuznets curve hypothesis. The long-term coefficients derived from the ARDL approach demonstrate that import increase the ecological footprint, whereas urbanization and clean energy consumption do not have an impact on environmental pollution in the long-term. In addition, the 2001 dummy variable is negative and statistically significant. The crisis in 2001 slowed down the economic growth rate. This situation also caused reduction of environmental pollution. Moreover, the long run estimates indicate that the EKC hypothesis is valid in Turkey. However, the turning point of per capita income was calculated as $16,045 that outside of the analyzed period. As economic activities increase, human pressure on nature continues to increase. Consequently, the only factor that reduces the ecological footprint has been determined as exports. In contrast, economic growth and clean energy consumption cannot be used as a tool to reduce the ecological footprint. Turkey needs a higher level of per capita income than the threshold level to improve environmental quality.

Characterisation of hydromorphological attributes is crucial for effective river management. In the Philippines, such applications are usually solely based on water quantity and quality. This paper uses the River Styles Framework as an alternative template for identifying the diversity of river morphodynamics as a valuable input to river management. Eight distinct River Styles (river types) were identified in the Bislak catchment (586 km2), north-west Luzon, indicating considerable geomorphic diversity within a relatively small catchment area. Three River Styles in Confined valley settings occupy 57% of the catchment area, another three in Partly-confined valley settings occupy 37%, and two in the remaining 6% are found in Laterally-unconfined valley settings. Five characteristic downstream patterns of River Styles were identified within the tributaries. We find that variation in channel slope for a given catchment area (i.e. total stream power) is insufficient to differentiate the type of river in a given reach. Hence, topographic analyses should be complemented with broader-framed, catchment-specific approaches to predict river character and behaviour. Geomorphologically-informed analyses can support management applications in the Philippines, explicitly incorporating understanding of river diversity and dynamics.

Published: December 2020

BackgroundThe Northwestern Escarpment of Ethiopian Rift Valley has been frequently affected by drought for decades in the major livelihood zones. This brought an adverse effect on the social and economic sectors because it affects significantly the smallholder farmers of the area. However, Most of these reviewed studies have limitations to show the evolutions, spatiotemporal drought frequencies, durations and severities in livelihood zone levels. Hence, the aim of this study was to monitor meteorological drought condition of the Alaje-Ofla (ALOF), Tserare Catchment (TC) and Raya Valley (RV) Livelihood Zones (LZ) from 1983 to 2016 using Standardized Precipitation Evapotranspiration Index (SPEI) at three months’ time scale. Both monthly Climate Hazards Group InfraRed Precipitations with Station data (CHIRPS) and Enhancing National Climate Service (ENACTS) temperature data (1983-2016) at moderate spatial resolution (i.e.,4 km-by-4km) were obtained from the National Meteorological Agency of Ethiopia. ResultsThis study uncovers seasonally recurring droughts that vary in severity, frequencies, and durations within as well as between the livelihood zones. The results indicated that severe drought occurred in all livelihoods zone of the study area from 1983/4 to 1991, while in the ALOFLZ and TCLZ relatively high droughts were observed. The severity and frequency of droughts were increased during the Belg (small rain) season, but decreased in Kiremt (summer) from the period 1989 to 2016. Hence, the severity of drought both on humans and livestock was severe in the area, particularly before the year 2001, but neither catastrophic drought nor food security in TCLZ and RVLZ was observed after year 2001.ConclusionStudying drought with long recorded meteorological data from a large number and uniformly distributed meteorological grids in small scale livelihood zones had great implications to identify the real trends of spatiotemporal meteorological drought. This enabled the researchers to investigate the real drought frequencies, severity, and durations in small scale areas. This study can support to improve the existing drought monitoring system and to build resilience to drought at household level.
