description: This paper presents the pursuit of [un]happiness from a critical standpoint, and it examines how [un]happiness is influenced by social, political, historical, and economic systems. A mix-methods pilot study was conducted to find out how U.S. southwestern borderland community feel about happiness. The research participants included students and persons from the local border region. [Un]happiness is a byproduct of social justice or lack thereof; hence, this theoretical study analyzes the implications of sustainable socioeconomic and unequal structures that produce it. It inquires how the fulfillment of basic existential needs and access to quality education can guarantee critical, authentic, and hopeful opportunities for a happier and healthier life. We question whether social justice opportunities for happiness and how the constitutional pursuit of happiness guarantee its effectiveness and applicability. How should education promote curricular and pedagogical programs that facilitate the foundational means of happiness and how to live healthier lives? The overall findings indicate that countries that distribute resources more equitably have fewer social problems. The paper discusses eastern and western paradigms and recommends educational programs that can influence happiness.

description: Maize plants displaying severe mosaic, chlorosis and necrosis were observed in five
provinces of Ethiopia. ELISA test from symptomatic samples revealed the presence of
maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV), two
components of maize lethal necrosis disease. In 2014 and 2015, surveys conducted in
Oromia, SNNP, Benishangul Gumuz, Amahara and Tigray regions showed that the
two viruses were present in a significant number of plants. Mixed infections were
detected and associated with severe severity and yield losses. The report of maize
-lethal necrosis disease in Ethiopia is of high level concern for producers in the country
because of the potential of an epidemic that can devastate maize seed and grain
production. According to this survey report MLND severity in SNNP was the highest
with a mean rate of 3.5, followed by Oromia, Benishangul Gumuz, Amahara and
Tigray with mean severities 3.2, 2.5, 2 and 1.5, respectively. It is estimated that
severely affected areas can experience a massive yield loss of over 95 % and this will
affect total maize yield produced in the country. Thus it is recommended that farmers
should avoid growing maize in consecutive seasons, continuous/stagger cropping,
movement of affected crop debris from one region to another; practice crop rotation
and intercropping with non-cereal crops, rouging out affected maize debris and
application of insecticides to curb the impact of the disease and improve maize yield.

description: The study yWas cohducted at the Plant Protection Laboratory of Haramaya
University in a controlled environment of 28±2°C temperature and 75±5% relative
humidity. The objective was to determine the effective doses of Azadirachta aulica
and Citrus sinensis peel powder for the management o f Sitophilus zeamais. The
treatments were arranged in completely randomized design (CRD) with four
replications. Fifty unsexed 3-6 days old maize weevil adults were introduced to
each glass jar containing 1 kg Sorghum bicolor (L.), variety muyra-2 seeds. Neem
seed and citrus peel powder were compared with Ethiolathion 5% dust and
untreated control at the rate o f 7.5. 1 5 ,2 5 , 50 and 100 g k g '1 o f seeds. Parent adult
maize weevil mortality, F, progeny emergence and percent protection, grain weight
loss, damage and germination at all rates of citrus peel powder (CPP) and neem
seed powder (NSP) showed significant differences over the untreated control
(P < 0 .0 l), except for grain damage (%) at 7.5 g CPP (P >0 .0 l). At the rate o f 25, 50
and 100 g both test botanicals resulted in 100% adult weevil mortality, 95-100%
grain protection, reduced weevil emergence, reduced grain damage, reduced grain
weight losses and produced statistically comparable efficacy with Ethiolathion 5%
dust (P<0.01). NSP at 7.5 and 15 g and all rates o f CPP did not reduce grain
germination rate, whereas at higher rate o f 25- 100 g NSP statistically decreased
germination o f the treated grains (P<0.01). Further research is warranted to assess
efficacy o f these botanicals under farmer’s storage condition.

description: Turcicum Leaf Blight (TLB) of maize which is caused by Exserohilum turcicum
(Pass.) Leonard and Suggs is a major foliar disease in Ethiopia causing yield loss in
the range of 13.6 to 56% depending upon the genotype. Field Experiments were
conducted for two consecutive years in two locations viz. Ambo and Bako
Agriculture Research Centers to study the temporal attributes of the disease. Six
parental lines which constituted tolerant (lineI), susceptible (Iine2), resistant
(Iine5) and three moderately resistant lines (lines 3, 4 and 6) selected from
highland maize screening tests were used for the experiments. A randomized
complete block design with three replications was used. In 2014, at Ambo, the
AUDPC and severity of lines I, 2 and 3 significantly varied from lines 4, 5 and 6
(P = 0.0008 and P = 0.0005, respectively). The apparent infection rate was not
significant among all the lines in the same year. However, there were no
significant variations in the AUDPC, severity and apparent infection rate of TLB
among the six lines in 2015. These parameters did not significantly vary in 2014
at Bako. TLB disease was explained by the Logistic model on maize lines land 4
in 2014 at Ambo while it was fitted by the Gompertz model on maize lines 2 and
3.TLB disease also explained by the monomolecular disease progress model on
lines 5 and 6. None of the models was able to effectively explain TLB disease
progress at Bako in 2014 and at Ambo in 2015. Additional studies involving more
maize lines and locations are recommended to adequately explain the epiphytotic
of the disease and to recommend resistant lines for breeding programs.

description: Water hyacinth [Eichhornia crassipes (Mart.) Solms] remains one of the worst
aquatic weeds worldwide. Its presence in Ethiopia was officially reported in Koka
Lake and Awash River about 60 years ago. A study was conducted for two years
to evaluate the integrated use of host-specific herbivorous weevil species
Neochetina eichhorniae and N. bruchi, and an indigenous fungal plant pathogen
(Alternaria alternata) for controlling water hyacinth in the lathhouse in the Rift
Valley of Ethiopia. Water hyacinth plants that grown in caged tanks were exposed
to one of eight treatments: control; only either of the weevil species (N.
eichhorniae or N. bruchi alone); the two weevil species (N. eichhorniae + N.
bruchi)\ the fungal spray (foliar application of A. Alternate); combination of the
weevils and fungal spray (N. bruchi, N. eichhorniae or N. bruchi and N.
eichhorniae + foliar fungal application). Water hyacinth plants that received the
two weevils combined with A. alternata showed a disease index (D l) of 90%
compared with Dl values of 70% and 60% recorded in N. bruchi combined with A.
alternata and N. eichhorniae with A. alternata, respectively. Application of both
weevils combined with A. alternate showed about 97% and 85% reduction in
number of new ramets and fresh weight, respectively. Thus, it is concluded that
application of the three agents together had an overall synergistic effect in
controlling water hyacinth.

description: The ability to distinguish between aggressive earnings management (aggressive accounting) and financial reporting fraud (fraud) is an essential characteristic for auditors in fulfilling their responsibilities. Yet little is known of how auditors make this distinction in practice. Perhaps due to the ambiguity in defining where aggressive accounting ends and fraud begins, few studies have attempted to investigate the distinction between the two types of financial manipulation. This current research provides evidence as to how auditors distinguish between aggressive accounting and fraud in practice. Specifically, this study examines which factors auditors invoke in determining whether an identified financial manipulation constitutes aggressive accounting or fraudulent accounting. Findings from interviews with senior auditors suggest these factors include managerial intent, compliance with Generally Accepted Accounting Principles, materiality level, and measurement subjectivity. Research findings have the potential to alleviate some of the ambiguity associated with distinguishing between aggressive and fraudulent accounting. As such, this study contributes to the earnings management, financial reporting fraud, and audit judgement research literatures.

description: In Ethiopia, common bean rust ( Uromyces appendiculatus) is the most destructive
disease constraining common bean production. Field experiments were carried out
at Hirna Research Sub-Station of Haramaya University in the 2010 main cropping
season to elucidate reaction o f released common bean varieties to rust infection and
to study the effect of integrated use o f host resistance and fungicide foliar sprays
on incidence o f the disease and its control. For the evaluation of common bean
varieties to rust disease the experiment was laid out in randomized complete block
design with three replications and 15 varieties and the experiment was laid out as a
randomized complete block design in factorial arrangement with three replications
for the management part. In the fungicide spray, three contact (i.e. Chlorothalonil,
Mancozeb and Copper hydroxide) and one systemic (Triadimefon) fungicides were
tested on a susceptible (Mexican-142) and a moderately resistant (Awash-1)
varieties. The research results obtained indicated that the evaluated common bean
varieties varied significantly in severity, area under disease progress curve, disease
progress rate and grain yield. Three reaction groups o f common bean varieties were
identified, viz. susceptible, moderately resistant and resistant. The resistant
varieties produced the highest grain yield. At Hirna the varieties, Kufanzik,
Haramaya, Melkadima, Gofta, Chore and Awash Melka were found to be resistant
to the disease. These varieties were also high yielders. However, in case seeds o f
resistant varieties are inadequate to cover the major growing areas, farmers can use
the moderately resistant varieties with fungicide sprays wherever the disease is a
pervasive and pressing problem. In the management study, lower rust incidence,
severity, area under progress curve and slower disease progress rate occurred on
the moderately resistant variety sprayed with Triadimefon than on the susceptible
variety with Triadimefon and/or with other fungicides. The integrated use o f
moderately resistant variety (Awash-1) with Triadimefon proved to be the best
management option producing the highest (2306.25 kg h a 'l) grain yield.
Triadimefon foliar spray reduced relative grain yield loss by 10.84% on the
moderately resistant variety Awash-1 compared to the susceptible variety Mexican-
142. In conclusion, integrated use o f Awash-1 with Triadimefon spray was found
to be the most effective bean rust management option.

description: Laboratory experiment was undertaken to study biology of Sitotroga cerealella on
five maize genotypes, viz. non-quality protein maize, quality protein maize
(QPM), sweet corn, pop corn and local maize. The data on insect biology, grain
physical and chemical characteristics were recorded. Results showed that S
cerealella reared on the sweet corn displayed the longest larval-pupal period (27.0
d). developmental time (42.67 d), longevity o f adult moth (10 days for female and
6.67 for male), egg hatching period (5.67 d) and the lowest survival percentage
(25.5%) and fecundity (87.83 eggs/female). On the contrary, QPM displayed the
shortest larval-pupal period (21.17 d), developmental time (34.83 d), longevity o f
moth (6.50 days for female and 3.83 for male), egg hatching period (3.83 d) and
the highest fecundity (140.38 eggs/female). Correlation coefficients between
insect biology and grain physfcochemical characteristics were calculated, yielding
a clear relationship between grain hardness, grain size, kernel weight, crude fat,
amylase, phenolic, and insect developmental traits. The harder and smaller size
kernels in combination with reduced fat content and increased amylase and
phenolic concentration had resulted in poor insect performance. These results
indicated that a single physical or chemical characters alone are not responsible
for suitability o f grain to S. cerealella unless combined together. Our study leads
to the conclusion that biology o f S. cerealella was related to the combined effect
of kernel physical and chemical characteristics.

description: Faba bean (Vicia faba L.) has a significant potential for nutrient source, income generation and soil fertility management in smallholder farming systems of northern highlands of Ethiopia. However, its cultivation is strongly hampered by the occurrence of the obligate root holo-parasite, crenate broomrape (Orobanche crenata Forskal). To gather baseline data for developing a sustainable crenate broomrape management, 33 faba bean growers' households in South Gondar, and South Wollo Zones of the Amhara Regional State and Southern Tigray of the Tigray Regional State of Ethiopia were surveyed during the 2018 cropping season using a structured questionnaire. Most of the respondents (61%) believed that crenate broomrape was introduced in the 1990s with grain meant for food aid. All respondents believed that the weed is highly problematic and difficult to control. Sixty-seven percent of the respondents practice cultural control to minimize its infestation but all perceived that the current management practices were ineffective. The rest of the respondents (33%) did not practice any control measure and preferred abandoning faba bean cultivation in their field. Thus, this survey work indicated that the spread and dense infestation of crenate broomrape is causing considerable impacts on faba bean production. A coordinated management strategy with intensive public awareness creation program that can restrict its infestation and associated socio-economic impacts on farming systems in northern highlands of the country is required.

description: Tef epilachna, Chnootriba similis, is an important pest of cereal crops in Ethiopia. It causes significant yield loss on barley under heavy infestation. The efficacy and application time of five foliar insecticides were evaluated to control C. similis on barley in two districts of Wolaita, southern Ethiopia during the short “Belg” and the main “Meher” rainy seasons of 2020. The trial was factorial in a randomized complete block design with three replications. The treatments were combinations of five insecticides (carbaryl, diazinon, imidacloprid, λ-cyhalothrin, malathion) and two application times (early and late). Early applications (tillering stage) of insecticides were either better or on par with the late applications (booting stage) in the two seasons and locations in terms of mortality of larvae, leaf damage and grain yield. Higher larval mortalities were recorded for the insecticides λ-cyhalothin (87 - 100%), carbaryl (84 – 100%), diazinon (78 – 99%), malathion (86 – 100%), and imidacloprid (71 – 97%). Barley protected with insecticides against C. similis had lower leaf damage and resulted in significantly higher yield. The insecticides carbaryl, λ-cyhalothrin, malathion, diazinon, and imidacloprid, applied at the early tillering stage of barley can effectively control C. similis on barley. The insecticide λ-cyhalothrin that consistently provided higher protection and gave the highest return is the best choice for the control of C. similis.

description: The objective of this study was to find and test entomopathogenic nematodes (EPNs) native to regions of Ethiopia where maize is grown with the aim of developing a biocontrol program against fall armyworm (FAW) Spodoptera frugiperda (Smith) and other arthropod pests. Six hundred seventy-nine soil samples were collected from eight regional states of Ethiopia between August and October 2019. From these collections, 28 EPN isolates, 13 from Steinernema genera and 15 from Heterorhabditis genera have been identified. All the 28 isolates identified from the survey and nine Ambo Agricultural Research Center’s isolates were tested using a single dose (500 infective juveniles ml-1(IJ)/ml) under laboratory conditions using FAW larvae in completely randomized design. Isolates, such as Aso-Tes-287 from Steinernema genera and Am-Ger-Tes-74, Am-Adm-Tes-369, and Z9 from Heterorhabditis genera caused significant larval mortality within eight days. Moreover, the LT50 values i.e., 3.5 to 6.7 days showed that these isolates are more virulent. These most virulent isolates were further tested for their potential in a pot experiment under wire house conditions at three different concentration levels (250, 400, and 600 IJ/ml) in randomized complete block design. The isolates Aso-Tes-287 and Am-Ger-Tes-74 resulted in higher mortality of 74.7% and 78.3%, respectively at 600 IJ/ml. The EPN isolates Aso-Tes-287 and Am-Ger-Tes-74 which caused higher mortalities within shorter periods, were promising bio-agents for the management of FAW. A confirmatory study is suggested to use the two promising bioagents for the management of FAW and other arthropod pests.

description: Orienting international English as a Second Language (ESL) students to research skills and discourses through bridging programs at the postgraduate level has been described in literature and is also explored in a range of text-books. The discussion regarding undergraduate research support is substantially less well developed, although research training at the undergraduate level is not uncommon in some disciplines. Content-based, team-taught bridging programs offer distinct advantages to students although they also require careful planning and consideration of integrated teaching and assessment. This paper presents a case study of the context and curriculum outline of an innovative three-week bridging program for international second-language medical research students undertaking a two-semester, third-year intercalated Bachelor of Medical Science (BMedSci) degree within the Bachelor of Medicine and Bachelor of Surgery (MBBS) program at the University of Melbourne. Independent qualitative and quantitative student evaluations of the overall concurrent English for Academic Purposes (EAP) support, and specifically the bridging program, are also provided. The paper highlights the potential for concurrent discipline-specific support for research students under a faculty-based student support program (Hawthorne, Minas and Singh 2004).

description: There has been a concerning presence of phytoparasitic nematodes on annual and biennial ornamental plants at Jimma University's agriculture campus. Rhizosphere soil samples were collected to elucidate the presence of plant parasitic nematodes associated with ornamental plants. The samples were collected from three locations of eleven different ornamental species, including Agapanthus africanus, Canna generalis, Cuphea ignea, Dahlia hybrids, Dianthus barbatus, Gerbera jamesonii, Impatiens balsamina, Impatiens hybrids, Pelargonium spp., Tagetes erecta and Zinnia elegans. Nematodes were extracted from 100 ml aliquot soil using the modified Baermann tray method. The study identified ten genera of plant parasitic nematodes, including Helicotylenchus, Hemicycliophora, Hoplotylus, Meloidogyne, Mesocriconema, Paratylenchus, Paratrichodorus, Scutellonema, Telotylenchus, and Trichodorus. Helicotylenchus was the most dominant genus with a mean population density of 126 individuals/100 ml soil, a frequency of occurrence (FO) of 64%, and a prominence value (PV) of 101 among all sampled ornamental plant species. Meloidogyne and Scutellonema followed with mean population densities of 129 and 70 individuals/100 ml soil, FOs of 48% and 39%, and PV of 89 and 44, respectively. The least important genera were Paratylenchus and Trichodorus, with an FO of 3% and mean nematode population densities of 10 and 17 individuals/100 ml soils, respectively. Molecular identification based on 18S small subunit (SSU) ribosomal DNA (rDNA) gene sequences revealed the species identity of Scutellonema bradys, Hemicycliophora conida and Telotylenchus ventralis. This study provides valuable information on nematodes associated with ornamental plant species vital for developing management plans in future landscape maintenance.

Insecticidal Potency of a New Bioactive Dipeptide from Bacillus velezensis AR1 Culture Supernatant Against Myzus persicae
Creators: name: Bayisa, Regassa Ayana
Publisher: name: Pest Managment Journal of Ethiopia
Year: 2021

description: The green peach aphid (Myzus persicae) has become a worldwide challenge causing high yield losses through direct plant attack and transmission of plant pathogens. A widespread resistance development against synthetic agrochemicals by the aphid and the negative impact of the chemicals used to manage the pest on human health, other organisms and the environment are other problems. Therefore, the aphicidal potency of the secondary metabolite from Bacillus velezensis AR1 was investigated under in-vitro conditions. The purification process was conducted using solid-phase extraction by Strata SI-1 column, thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC). Then, the purified EA3T3 fraction was analysed with the nuclear magnetic resonance (NMR 1H, 13C, H-H COSY, HSQC, and HMBC) and the metabolite was identified as 5-N-tyrosinylornithine. The aphicidal potency of the metabolite on Myzus persicae mortality was tested using three concentrations over 24 to 72h periods of exposure in a laboratory bioassay in comparison with a biopesticide E-II. The biopesticide EII caused the highest mortality of the aphids; 89% at 72 hr. The purified metabolite caused a mortality rate of 40.74±6 to 66.67±5% at 1 to 4µg mL-1 concentrations after 72h of exposure. The aphid mortality increased with the increase in concentration and duration of exposure to EA3T3. The lowest LD50 was attained at 72h of exposure. Therefore, the bioactive metabolite produced by B. velezensis AR1 is potent against the green peach aphid Myzus persica and has the potential to be used for the management of aphids.

description: The root-knot nematode, Meloidogyne incognita, can severely damage hot pepper plants (Capsicum annum and C. frutescens). Therefore, it is crucial to develop effective management strategies. The impact of aqueous crude leaf extracts from Vernonia amygdalina and Lantana camara and organic soil amendments with vermicompost and poultry manure was investigated in an open-field pot experiment on three pepper genotypes (Oda Haro, Acc.03, and Melka Awaze). The growth performance, yield, and nematode population were assessed. Twenty-seven treatments, including the untreated checks, were arranged in a factorial RCBD in three replications. Plots treated with leaf extracts and/or organic soil amendments resulted in significantly lower number of root galls, egg masses, and nematode populations than the untreated checks in all the pepper genotypes. The combined treatments were more effective than individual treatments in all the genotypes. The lowest nematode population was on the genotype Melka Awaze Lantana camara with vermicompost on genotype Melka Awaze, L. camara with poultry manure on genotype Oda Haro, and V. amygdalina with vermicompost on genotype Acc.03 sustained fewer root galls, egg masses and nematode populations. On the genotype ‘Oda Haro’, the untreated control gave significantly lower values for the number of pods, marketable pods, number of branches and plant height than the remaining treatments except V. amygdalina applied without soil amendments for number of branches. Similarly, on the genotype‘Acc.03’, except L. camara without soil amendments for number of branches and V. amygdalina and poultry manure for plant height, values were significantly lower in the untreated control than the other treatments. Vermicompost enhanced the growth and yield of pepper and reduced the number of root galls, egg masses and nematode populations. Therefore, applying leaf extracts and organic soil amendments appeared promising to control M. incognita.

description: Chickpea fusarium wilt (CFW) caused by Fusarium oxysporum f.sp. ciceris has become a great threat to chickpea production in Ethiopia. A field survey was conducted to determine the distribution and association of CFW with biophysical factors in the Central Rift Valley of Ethiopia in the 2019/20 main cropping season. The associations of CFW incidence with independent variables were analyzed using a logistic regression model. A total of 68 fields were assessed in four districts and results revealed that all the surveyed fields were infected with CFW. However, substantial variations were observed in CFW incidence across the surveyed districts. The mean incidence varied from 31.79% in Lume to 55.81% in the Gumbichu district. Variables like district, crop growth stage, variety, previous crop history, seed source, crop density, and weed density had a very highly significant (P<0.0001) association with disease incidence in reduced multiple variable models. Associations between disease parameters and chickpea variety were also observed to be significant in the reduced model. Results from this study showed a 100% prevalence of CFW in the study area, implying the need for proper intervention. Emphasis on proper agronomic practices such as the use of improved seeds, appropriate sowing date, cropping pattern, and weed management should be given in the integrated management of CFW in the study area and other related agroecologies.

description: Hermetic storage has been introduced and disseminated in some parts of Ethiopia; although  their efficacy in protecting seeds has not been studied. Thus, a study was conducted to determine whether different hermetic storage protect or not tef, durum wheat, lentil, and chickpea seeds from damage by storage insect pests over various storage periods. The hermetic storage tested were GrainPro super bag, Purdue Improved Crop Storage (PICS) bag, and fertilizer bag, while polypropylene bag was used as control. In each bag 10 kg of insecticide untreated seeds of tef, durum wheat and chickpea and 4 kg of lentil seed was put and stored for 6, 12, 18 and 24 months. The treatments were arranged in two factor nested design and treatments were replicated three times. Only lentil and chickpea seeds were infested by Adzuki bean beetle (Callosobruchus chinensis). It was found that throughout the tested storage periods, lentil seeds stored in PICS bag and GrainPro super bag had the lowest proportion of seeds with egg or hole; the lowest average number of eggs per seed; and holes per seed than seeds stored either in polypropylene bag or fertilizer bag. Relatively high level of infestation was found on chickpea seeds stored in a single inner layer GrainPro super bag and polypropylene bag. There were no insect infestations in both tef and durum wheat seeds stored in all packaging materials. Therefore, PICS and GrainPro super bags (as double layer) are effective in protecting both cereals and pulses from insect pests in storage.

description: Pyrrole- and imidazole-containing polyamides can be tailored to recognize the DNA 6–8 base pair sequence. We found that adding a second amino group via the N1-position of pyrrole or imidazole in polyamides could enhance their DNA binding affinity and water solubility while retaining sequence specificity. Synthesis of the key 1-substituted-4-nitropyrrole (and imidazole)-2-carboxylic acid building blocks are described. [Supplementary materials are available for this article.
