This study applies a cross-sectional design. The location of data collection was conducted in the Cibanteng Village area, Ciampea District, Bogor Regency, West Java. The population in this study were families living in Cibanteng Village, Ciampea District. The sampling unit in this study is the family with the respondent is a wife. The sampling was taken purposively and obtained samples of 40 families. The results of the study showed that in the planning implementation, the majority of families never wrote their life plans in the family. The majority of mothers control domestic problems such as housework, children's education, and childcare. The structure of communication and decision making in the family carried out by the majority family only involves husband and wife. The higher the productive time allocated by the wife, the smaller the allocation of leisure time and household time. Also, the higher the social time allocation devoted by the wife, the smaller the allocation of household time and personal time allocation.
Screening, Sensitivity, Specificity, and So Forth: A Second, Somewhat Skeptical, Sequel
Authors: Trevethan Robert
Published: June 2019

This article is concerned with the sensitivity, specificity, predictive values, and other metrics associated with screening tests. It has direct origins in two previous articles. In this third article, the author of the first article writes about topics and issues that were addressed only minimally in his previous article and expands on topics raised by authors of the second article. In particular, attention is turned to wording and terminology that can be idiosyncratic and confusing with regard to screening versus diagnosis as well as to issues associated with reference (“gold”) standards and screening tests, and to the importance of cutpoints and prevalence in relation to metrics associated with screening tests. The primary aims are to help readers attain clarity about topics that they might have felt unsure about; gain reassurance about conceptual difficulties in the field that, once recognized for what they are, can become less problematic because it is possible to be confident about not being confident; and, where appropriate, adopt an appropriately skeptical attitude about screening tests and their associated metrics. Examples are drawn from the use of ankle–brachial and toe–brachial indices for identifying peripheral artery disease, although wider applicability is intended.

Published: June 2019

A avicultura é uma atividade agropecuária de grande importância econômica no Brasil e em outros países. Apresenta dois segmentos diferentes: o de corte para produção de carne e o de postura para produção de ovos. A análise da rentabilidade no setor agropecuário de produção é imprescindível para melhor administração do empreendimento, controlando os gastos e analisando a rentabilidade. No IFPB-Campus Sousa, onde funcionam cursos técnicos e superiores da área de ciências agrárias, o setor de avicultura tem a função de subsídio para aulas práticas, e parte da produção é destinado ao refeitório e agroindústria, sendo consumidos pelos próprios alunos. O presente trabalho teve por objetivo analisar a produção de ovos no setor de criação de galinhas de postura do IFPB, avaliando os custos de produção, a produtividade e rentabilidade.  Observou-se que existem certas variações de acordo com a demanda da instituição, porém a atividade se mostrou lucrativa. As receitas cobrem os custos durante quase todos os meses, exceto quando aumenta a demanda para atender a necessidade alimentar dos alunos. A relação custo benefício para os meses de janeiro a julho apresentou-se positiva, expressando valor de R$0,94 centavos.

Published: June 2019

A cultura do feijão-caupi possui grande relevância econômica e social na região Nordeste do Brasil. O trabalho foi realizado com o objetivo de avaliar a maturação e qualidade fisiológica de sementes de feijão-caupi, cultivares BRS Guariba, BRS Novaera e BRS Marataoã. O delineamento experimental foi em subparcelas dispostas em blocos casualizados, com quatro repetições. As colheitas iniciaram cinco dias após a abertura de 50% das flores e a partir daí colheitas a cada cinco dias, totalizando oito colheitas. Constatou-se que a maturidade fisiológica das cultivares está compreendida entre os 30 DAA para a cultivar BRS Novaera e aos 35 DAA para BRS Guariba e BRS Marataoã, uma vez que nesses períodos as sementes encontram-se com o máximo de matéria seca e máxima germinação e vigor, além de redução significativa do teor de água que é fundamental para preservação da sua qualidade. A maturidade fisiológica ocorreu em épocas diferentes entre as cultivares de feijão-caupi e as épocas de colheita apresentaram um bom indicativo para discriminar o momento ideal de realização da colheita. Os testes de teor de água, massa seca de sementes, primeira contagem de germinação, germinação, condutividade elétrica e envelhecimento acelerado foram eficientes para determinar a maturidade fisiológica das sementes.

Myracrodruon urundeuva Allemão é uma espécie propagada geralmente com o uso de sementes. No entanto, a escassez hídrica na região semiárida pode comprometer a produção ou causar a rápida perda de vigor de suas sementes. Uma das alternativas de propagar a espécie quando há limitação de sementes é o uso da técnica de miniestaquia. O trabalho teve como objetivo avaliar minicepas de M. urundeuva de origem seminal, a partir do 2º ano de seu estabelecimento, submetidas a diferentes alturas de decepa (10, 25 e 40 cm) e a eficiência do uso de extrato de tubérculos de Cyperus rotundus L. na sobrevivência e no enraizamento de miniestacas. A alta taxa de sobrevivência das minicepas e a boa produtividade de propágulos indicam que a miniestaquia tem grande potencial para ser utilizada nesta espécie. A decepa à 10 cm é a mais indicada, pois permite o início da produção dos propágulos mais cedo e consequentemente o retorno do investimento mais rápido. Este estudo demostrou o potencial do extrato de C. rotundus como uma alternativa econômica a ser utilizada na clonagem de M. urundeuva, uma vez que o seu uso aumentou a taxa de enraizamento.

Cnidoscolus quercifolius Pohl (faveleira) é espécie arbórea nativa do bioma Caatinga, amplamente utilizada pelas populações locais inseridas neste bioma, no tratamento de processos inflamatórios. Esta pesquisa teve por objetivo avaliar a ausência e presença de ácido indol butírico (6,0 g L-1 de AIB) e seis substratos, compostos de fibra da casca de coco verde (FC), pó da casca de coco verde (PC) e rejeito de vermiculita (RV) na produção de mudas de faveleira pela técnica clonal de alporquia. Observações semanais na superfície do substrato foram realizadas para detectar o surgimento de raízes no alporque, até 90 dias. Os ramos com os alporques foram removidos e coletados os seguintes dados: alporques sem calos; alporques com calos (formação de massa celular indiferenciada na região do anelamento); alporques com primórdios radiculares e alporques enraizados. Nos alporques enraizados, analisou-se o número de raízes, comprimento da maior raiz (cm) e massa seca das raízes (g). Por meio da contagem dos alporques enraizados foi calculada a porcentagem de enraizamento dos alporques. O uso do AIB foi eficiente no incremento do comprimento, número e massa seca de raízes. O substrato com 1/3 de fibra da casca de coco verde + 1/3 de pó da casca de coco verde + 1/3 de rejeito de vermiculita é o mais eficiente para o enraizamento de alporques em ramos de faveleira e de baixo custo.

Authors: Bhatnagar Anju
Published: June 2019

The essential oils of Cymbopogon flexuosus (lemon grass) of the family Poaceae collected from different altitudes of the Uttarakhand region of Himalaya were subjected to detailed GC/MS analysis in order to determine the variation of concentration in their constituents. The GC/MS analysis led to the identification of 29 constituents forming 90.62 to 93.58% of their total oil content. The major constituents were citral, geraniol, citronellol,citranellal, linalool, borneol, ?-myrcene limonene, ?-caryophyllene, camphene, ?-cadinene, ? terpineol, neryl acetate and heptenone. Plants collected from 450 m altitude afforded citral (74.58 %) [a isomeric mixture of geranial and nearl] as a major constituents whereas only a less percentage of citral (64.21%, 68.29%) was found in the plants collected from two other altitudes i.e 250m and 1000m respectively. The geraniol, cam-phene and neryl acetate were obtained in a high concentration form the plants collected at 250 m altitude but in the plant from two other altitudes, it was found only in less proportion. Similarly, ?-cadinene, ?-terpineol and camphene were the major constituents of plants at 1000m altitude but in other plants it was detected in very low concentration. Since, the concentration of plant constituents affected by altitude and season, medicinalproperties of such plants and their use in biological application would vary accordingly.

The samples were analyzed for Dissolved oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) ammonia and heavy metals . The study highlighted the seasonal variations of physicochemical characteristics and also the effects of mass bathing and religious activities on water quality of the religious sites. Although the water was reported as safe in terms of DO content, total ammonia, BOD and the values of COD before the religious rituals but the values exceeded the maximum permissible limit {DO (0.8±0.1, 0.76±0.11), BOD (25.07±0.13, 18.13±0.13),COD (131.9±2.08), Ammonia (2.31±.23, 6.57±0.02) Iron (5890 µg L-1) and Zinc (200 µg L-1)} after mass bathing and religious rituals indicating that the water was not suitable for drinking as well as bathing purposes after the rituals/mass bathing. So, bathing during/after such rituals may become a health hazards to the bathers or users of the water and also may affect the aquatic biota, further depleting it. There is thus a need of regular monitoring and regular application of suitable remedial measures to prevent the depletion of the quality of lentic waters.

Published: June 2019

Glass manufacturing process is a very tiresome job and the working near by the furnace makes tasks more difficult for workers as the environment is very hot. Apart from working in a hot environment various awkward postures was adopted while performing various activities which are monotonous and repetitive in nature and resulted in discomfort of various body parts. The workers perform various task and activities in extremely hot environment for at least 6 hours a day. In order to identify the various discomfort body regions, a total of 120 samples were selected conveniently from one of the glass manufacturing unit of Western UP for body mapping exercise. The study findings revealed that 37.50 % respondent reported pain in their wrist followed by lower back (30.82 %) and knee pain (27.50 %.) The other discomfort regions in body were neck, shoulder, upper back, elbow/forearm, thigh and ankle and foot. The problem in the wrist  were more prominent among blowers (59.46 %) followed by ball makers (50.00 %).While problem of lower back found to be more common among blowers (45.95 %) and mold closers(26.92 %) and helpers i.e.30.43 %. Relationship between task performed and the level of discomfort was found to be significant (at 5%) in neck, lower back, wrist/hand and shoulder region. Thus, the study reveals that due to the monotonous, repetitive and continuous task performed by the workers, there is an onset of musculoskeletal discomfort (MSD) which may lead to disorders in due course of time which will affect their life.
Role of extension professionals in determining marketing behaviour of the farmers indulged in Horticulture sector in Indian context: A review
Authors: Kanwal Shubhangi , Kashyap S.K.
Published: June 2019

The companionship of advanced technology and easy outlay for the primary products have always been a prime focus to boost economy of the nation. Although, India has gone through a major transformation from being food deficient to now the leading producer and exporter of many agricultural commodities. The socio-economic condition of the farmer has not witnessed a noticeable change. The root cause identified by the researchers being the existence of long supply chains, lack of awareness, inadequate infrastructural facilities, etc. Researches analyzing the marketing behaviour of the farmers may help in identifying the constraints faced by the farmers in marketing their produce for optimum returns. Also, results may help to purview the factors contributing to better marketing by analyzing the varied behaviour of the farmers. Proper analysis, devising the effective strategy and its implementation require well-equipped extension professionals with upgraded skills and futuristic vision.
Multiple metal tolerance of Paenibacillus dentritiformis isolated from metal contaminated soils west Godavari district (Andhra Pradesh)
Authors: Sridevi V. , Raghuram M.
Published: June 2019

Sugar industrial effluents possess high amounts of toxic pollutants and contaminate the receiving sites. Treatment of contaminated sites by using microorganisms provides an alternate to conventional methods hence demands in the identification of metal tolerant microorganisms has been increasing day by day. Therefore in this study soil samples collected from Tanuku sugar factory residual effluent point (bank of Gosthani river), west Godavari district A.P were analyzed for the bacterial tolerance to Copper (Cu), Zinc (Zn) and Lead (Pb) in their chloride forms. Additionally, the study was carried out to identify the metal tolerant bacteria by morphological, biochemical and 16S rRNA gene sequencing studies. Four potential bacterial isolates were selected to analyze metal tolerance against CuCl2, ZnCl2, and PbCl2. The sequences were compared with those in NCBI and submitted in gene bank with accession numbers MK100333 (Paenibacillus cookie), MK100334 (Bacillus cereus), MK100335 (Aneurini bacillus sp) and MK100387 (Paenibacillus sp.). A Phylogenetic tree was constructed to Paenibacillus sp. the highly efficient bacterial strain among the four isolates using MEGA 7 soft ware. The results of this study showed that P. dentritiformis had multiple metal tolerances (Cu, Zn and Pb) up to 500mg/L after 72 hrs.  The identified bacterial strain proved to be the strong heavy metal tolerant bacterial strain. Hence, its usage will be helpful in the treatment of heavy metals specifically Cu, Zn and Pb contaminated soils and further optimization of these cultures is required to improve its metal resistant capacity.

Fusarium wilt is one of the major diseases of tomato causing extensive loss of production. Exploration of agriculturally important microbes (AIMs) for management of the tomato wilt is an ecofriendly and cost effective approach. In the present study, a total 30 Trichoderma and 30 bacterial isolates were screened in the laboratory for their biocontrol activity against Fusarium oxysporum f.sp. lycopersici (FOL). Out of all the isolates tested, Trichoderma asperellum BHU P-1 and Ochrobactrum sp. BHU PB-1 were found to show maximum inhibition of FOL in dual culture assay. Both the microbes also exhibited plant growth promoting activities such as phosphate solubilisation, production of siderophore, hydrogen cyanide (HCN), indole acetic acid (IAA) and protease activity. These microbes could be evaluated further in greenhouse and field studies for their potential use in management of Fusarium wilt of tomato.
Do Relative Advantages in STEM Grades Explain the Gender Gap in Selection of a STEM Major in College? A Multimethod Answer

Published: June 2019

Using a multimethod approach, we investigate whether gender gaps in STEM (science, technology, engineering, and mathematics) major declaration in college are explained by differences in the grades that students earn in STEM versus non-STEM subjects. With quantitative data, we find that relative advantages in college academic performance in STEM versus non-STEM subjects do not contribute to the gender gap in STEM major declaration. To explore alternative explanations for gender gaps in major declaration, we analyze interviews with college seniors, finding that they recognize many other factors, including their interests in subject matter and confidence, are key in pushing them from STEM or pulling them into non-STEM majors. We conclude that future research seeking to account for gender gaps in STEM majors must extend beyond academic performance.
Making Space for Social Integration
Authors: Janson Annick , Janson Melissa
Published: June 2019

This work tested an ‘Intentional
invitation’ mechanism to facilitate social integration in a small scale setting.
Working with community organisations to design inclusive environments, we
identified and addressed specific barriers to social inclusion and designed a
series of interventions to foster engagement, from early intervention to
in-situ encounters during creative community pop-up events. Intentional
invitations proved effective in facilitating the engagement of people with
disability. This in turn allowed for authentic interactions between all participants
to unfold in a community setting.

Data collected via participant
observation and interviews reveal new perspectives about disability and
experiences of togetherness. Our aim was to facilitate engagement of people
with disability as a channel for authentic contribution bringing potential
societal gain within our communities. Findings point to possible changes in
professional practice that would encompass intentional invitation mechanisms
under the Keys to Citizenship (Duffy, 2015) framework.
Black soldier fly larvae as the major protein component for Nile tilapia feeds
Authors: FRANCIS OGUTA JOB
Published: June 2019

The research on black soldier fly as a fish feed for caged Nile tilapia in River Nile at Namasagali; aimed at comparing convectional feeds and feeds with black soldier fly larvae as the major protein source was focused on setting impact on fish feed acquisition challenges by attaining cheap and environmentally friendly feeds from the locally available trash materials that have been abandoned in our environments (BSF).Caged Nile tilapia was fed twice a day on different feeds (conventional feeds and pellets with black soldier fly larvae replacing the protein content), initially at 30% body weight then later at 15% body weight and studied for three months. Every feed type was used in three different cages; which cages were arranged serially with each feed type interconnected to the other cages fed on the other feed type.Tilapia fed on conventional feeds showed a generally higher growth response than those fed on feeds with BSFL as the major protein content. The feed with BSFL as the protein source was so fatty and smelt wacky although palatable to the fish.Nyakeri Evans Manyara sighted a similar outcome in his thesis (optimization of production of black soldier fly larvae for fish feed formulation) submitted to School of Agricultural and Food Sciences Jaramogi Oginga Odinga University of Science and Technology, which showed that the growth trend of fish stocked at the same average initial weight and fed on the FM and BSFL diets were similar throughout the feeding period but with BSFL fed fish rambling FM fed fish.From the first date BSFL was introduced in the diet, 56Kgs of each feeds were used for each treatments but 271,600 and 156,800 Uganda shillings were used for the same quantities of conventional feeds and BSFL feeds respectively.
