PRODUCT RANKING: MEASURING PRODUCT REVIEWS ON THE PURCHASE DECISION

The development of the digital world today has had a significant impact on the industrial sector, one of which is the development of e-commerce. E-commerce is one of the platforms used by consumers in searching for information related to the needs of both products or services. Rating of a product plays an important role that can help consumers to support purchasing decisions and reduce search costs. Many factors can influence online purchasing decisions such as ewom, celebrity influencers, and online discounts, but very few studies have examined product ratings in determining purchasing decisions. This study aims to obtain results regarding the effect of product rating and web quality on purchasing decisions among private university students in Bandung. This type of research is an explanatory research that intends to explain the position of the variables studied and the relationship between one variable and another. The sample used in this study was 100 6th semester students with a focus on 3 classes of business and management faculty. The results showed that there was an influence between product rating and web quality variables on purchasing decisions. Although the results show that the effect is not large enough, these two factors, especially product ratings, are one of the variables that are often used by consumers in supporting online purchasing decisions.
Determinants of Farmers' Access to Extension Services and Adoption of Technical Inputs: Evidence from India

This paper examines the determinants of farmers' access to agricultural extension services and adoption of technical inputs. It also attempts to identify what works best for Indian agriculture. Based upon all-India unit-level data of 35,200 farming households surveyed by the National Sample Survey Organisation (NSSO) under the 70th round in 2013, it applies the binary logistic regression model. The study underlines that the ‘Access' to agricultural extension services does not guarantee ‘Adoption' of the technologies or better farm practices, as all the variables emerging as significant in case of ‘Access' do not emerge as significant for ‘Adoption'. The study finds the strong influence of personal and household characteristics on both ‘Access' and ‘Adoption'. However, socioeconomic and technology variables such as caste, gender, religion, and usage of ICT are found to be important for ‘Access' but not for the ‘Adoption'. The paper underlines that physical forms of extension services are far more important than the modern ICT driven services in the developing countries like India. It, therefore, recommends significant strengthening of these services with more generous government support.
Cell Tracking of Adult Neural Stem Cells From The Subependymal Zone In Vitro Reveals Cell Type-Specific Impacts On Cell Cycle Progression By The Extracellular Matrix Molecule Tenascin-C

Adult neurogenesis has been described in two canonical regions of the adult central nervous system (CNS) of rodents, the subgranular zone (SGZ) of the hippocampus and the subependymal zone (SEZ) of the lateral ventricles. The stem cell niche of the SEZ provides a privileged environment composed of a specialized extracellular matrix (ECM) that comprises the glycoproteins tenascin-C (Tnc) and laminin-1 (LN1). In the present study, we investigated the function of these ECM glycoproteins in the adult stem cell niche. Adult neural stem cells (aNSPCs) of the SEZ were prepared from wildtype (Tnc+/+) and Tnc knockout (Tnc-/-) mice and analyzed using molecular and cell biological approaches. A delayed maturation of aNSPCs in Tnc-/- tissue was reflected by a reduced capacity to form neurospheres in response to epidermal growth factor (EGF). In order to examine a potential influence of the ECM on cell proliferation, aNSPCs of both genotypes were studied by cell tracking using digital video microscopy. aNSPCs were cultivated on three different substrates, namely poly-D-Lysine (PDL) and PDL replenished with either LN1 or Tnc for up to six days in vitro. On each of the three substrates aNSPCs displayed lineage trees that could be investigated with regard to cell cycle length. The latter appeared reduced in Tnc-/- aNSPCs on PDL and LN1 substrates, less so on Tnc that seemed to compensate the absence of the ECM compound to some extent. Close inspection of the lineage trees revealed a subpopulation of late dividing aNSPCslate that engaged into cycling after a notable delay. aNSPCslate exhibited a clearly different morphology, with a larger cell body and conspicuous processes. aNSPCslate reiterated the reduction in cell cycle length on all substrates tested, which was not rescued on Tnc substrates. When the migratory activity of aNSPC-derived progeny was determined, Tnc-/- neuroblasts displayed significantly longer migration tracks. This was traced to an increased rate of migration episodes compared to the wildtype cells that rested for longer time periods. We conclude that Tnc intervenes in the proliferation of aNSPCs and modulates the motility of neuroblasts in the niche of the SEZ.
Simulations of Ozone Feedback Effects on the Equatorial Quasi-Biennial Oscillation with a Chemistry–Climate Model

Ozone feedback effects on the quasi-biennial oscillation (QBO) were investigated with a chemistry–climate model (CCM) by modifying ozone abundance in the radiative process. Under a standard run for 50 years, the CCM could realistically reproduce the QBO of about a 28-month period for wind and ozone. Five experiment runs were made for 20 years through varying ozone abundance only in the equatorial stratosphere from 100 to 10 hPa by −40, −20, −10, +10, and +20%, respectively, after the chemistry module and transferring the resultant ozone to the radiation calculation. It was found that the modification of ozone abundance in the radiation substantially changed the period of the QBO but slightly influenced the amplitude of the QBO. The 10% and 20% increase runs led to longer QBO periods (31 and 34 months) than that of the standard run, i.e., lengthening by 3 and 6 months, while the 10%, 20%, and 40% decrease runs resulted in shorter periods (24, 22, and 17 months), i.e., shortening by 4, 6, and 11 months. These substantial changes in the QBO period in the experiment runs indicate that the ozone feedback significantly affects the QBO dynamics through the modulation in solar heating.
Purpose-driven leadership and organizational success: a case of higher educational institutions

PurposeThis paper aims to examine the relationships between organizational purpose, leadership practices and sustainable outcomes for universities in emerging economies. We propose that a strong sense of purpose is a fundamental and defining feature in the leadership practices of these institutions, which ultimately contributes to their success.Design/methodology/approachThe authors present a research model that defines the relationships between a sense of purpose, leadership practices, student success outcomes, alumni involvement outcomes and societal reputation outcomes. Over 200 higher education administrators in India participated in the study.FindingsThe institutions' sense of purpose directly relates to their leadership engagement practices and their student success outcomes. Student success outcomes are a crucial linkage between leadership engagement practices and alumni involvement outcomes to achieve their societal reputation.Practical implicationsAs competitiveness intensifies, educational institutions under resource constraints must differentiate their organizational practices. This paper demonstrates how their core purpose and leadership actions result in achieving effective outcomes and overall sustainable societal reputation.Originality/valueThere is a significant difference between having an organizational purpose and enacting that purpose through their leadership practices. These results highlight the cascading effect from the institution's fundamental sense of purpose to their leadership practices and the positive outcomes of student success, alumni involvement and societal reputation.
Microencapsulation of Anchovy Fish Oil (Engraulis encrasicolus) with Fish Protein (Equulites klunzingeri) Isolate: Nutritional Assessment

Fish protein isolates extracted from underutilised fish species were used for coating material of anchovy oils and their nutritive value was investigated in this study. For this purpose, Klunzinger’s ponyfish (Equulites klunzingeri) proteins were extracted by using pH shifting process. Micro particles were prepared with anchovy oil (Engraulis encrasicolus) as core material (10%), and as wall materials a ratio of 5% and 10% fish protein isolate (FPI) was used. Maltodextrin (DE: 18:20) was added to both groups in a ratio of 10%. The emulsions were fed immediately into a Buchi Mini Spray Dryer (B290, Switzerland). The inlet temperatures, feed rate and aspiration rate were maintained at 160 oC, 15 mL/min and 35m3/h, respectively. The lipid, protein and moisture contents of anchovy oil microcapsules containing 5% FPI and 10% FPI were found as 43.76-43.09%, 4.34- 9.82% and 3.95-3.92%, respectively. The main amino acids in microcapsule samples were lysine, glutamic acid, and leucine which constituted in the range of 349-578 mg/100 g sample for microcapsules containing 5% FPI, and 805-1547 mg/100 g sample for microcapsules containing 10% FPI. In addition to that, essential and non-essential amino acids (E/NE) ratio for microencapsulated fish oil with 5% FPI and 10% FPI were determined 0.92 and 0.95, respectively. As a result of this study, it can be concluded that the addition of fish protein isolate enhanced the nutritive value of microencapsulated fish oil.
South American fires and their impacts on ecosystems increase with continued emissions

<p>Unprecedented fire events in recent years are leading to a demand for improved understanding of how climate change is already affecting fires, and how this could change in the future. Increased fire activity in South America is one of the most concerning of all the recent events, given the potential impacts on local health and the global climate from loss of large carbon stores under future environmental change. However, due to the complexity of interactions and feedbacks, and lack of complete representation of fire biogeochemistry in many climate models, there is currently low agreement on whether climate change will cause fires to become more or less frequent in the future, and what impact this will have on ecosystems. Here we use the latest climate simulations from the UK Earth System Model UKESM1 to understand feedbacks in fire, dynamic vegetation, and terrestrial carbon stores using the fire-enabled land surface model JULES-INFERNO, taking into account future scenarios of change in emissions and land use. Based on evaluation of the modelling framework performance for the present day, we address the specific policy-relevant question: how much fire-induced carbon loss will there be over South America at different global warming levels in the future? We find that burned area and fire emissions are projected to increase in the future due to hotter and drier conditions, which leads to large reductions in carbon storage especially when combined with increasing land-use conversion. The model simulates a 38% loss of carbon at 4&#176;C under the highest emission scenario, which could be reduced to 8% if temperature rise is limited to 1.5&#176;C. Our results provide a critical assessment of ecosystem resilience under future climate change, and could inform the way fire and land-use is managed in the future to reduce the most deleterious impacts of climate change. </p>
Study on Phytochemical Screening and Antimicrobial Activity of Adhatoda Vasica

Vasaka or Adhatoda vasica (L.) Nees is a well-known plant medication in Ayurvedic and Unani medicine. Cough, whooping cough, cold, and clinging phlegm in the mouth, throat, chest, or breast have been traditionally treated using Adhatoda vasica nees. The present study aimed to evaluate Adhatoda vasica's phytochemical analysis and antimicrobial activity. The preliminary phytochemical screening of alkaloids, steroids, saponins, phenols, and terpenoid yielded positive results. The antibacterial activity of ethanol and leaf extracts of Adhatoda vasica was investigated in this study. Based on the data presented herein, the largest zone of inhibition was found to be against Pseudomonas aeruginosa. The antifungal activity of Aspergillus clavatus was proven to have the maximum zone of inhibition. As a result, the current method may be effective in identifying new bioactive compound for the development of novel medications. Thus, it may be used as a strong antimicrobial agent against Pseudomonas aeruginosa pathogens.
Airline Chief Executive Officer and Corporate Social Responsibility

The aim of this research is to explore the determinants of airline CSR. Stakeholder theory is the theoretical underpinning. Chief executive officers (CEOs) are the research target, which is theoretically underpinned by upper echelon theory. For data collection, this study used data from COMPUSTAT, EXECUCOMP, KLD MSCI, LinkedIn, and the Bureau of Economic Analysis. Standard industry classification code 4512 was employed to obtain information on airline companies. Moreover, the number of observations was 154, the number of firms was 15, and the study period was 1999–2016. CSR domains include employment, the environment, and the product. The explanatory attributes are the CEO’s age, tenure, education, share ownership, stock option, and duality. Ordinary least squares and feasible generalized least squares regression analyses were executed for hypothesis testing. Regarding the results, employment CSR was positively affected by CEO age. This study found an inverted U-shaped relationship between CEO tenure and environmental CSR. Environmental CSR was also negatively influenced by stock options. Product CSR was positively associated with CEO age, whereas it was negatively associated with CEO duality.
Perspectives of service agencies on factors influencing immigrants’ mental health in Alberta, Canada

Newcomers to Canada experience resettlement challenges that affect their mental well-being. Guided by an intersectionality theoretical framework, we sought the perspectives of immigrant service agencies on factors influencing immigrants’ mental health in Alberta, Canada. Data were collected by means of qualitative interviews and focus groups with immigrant service providers. Our data analysis identified seven themes – precarious immigration status, employment discrimination, social isolation, socioeconomic pressures, sociocultural stress, gender and age-related vulnerabilities, and lack of appropriate mental health supports – reflecting the major intersecting determinants of immigrants’ mental health. We propose policy interventions for addressing the mental health vulnerabilities of immigrants.
Politização de controvérsias científicas pela mídia brasileira em tempos de pandemia: a circulação de preprints sobre Covid-19 e seus reflexos

Diante da profusão de preprints durante a pandemia, a proposta do artigo é entender como ocorreu a circulação desses produtos científicos, em especial, nas matérias veiculadas em portais de notícia, quais enquadramentos são utilizados e como essas matérias são percebidas pelos usuários no Facebook. Os procedimentos metodológicos empregados na pesquisa foram a análise de dados bibliográficos, a análise de enquadramento midiático e a escuta social. Os resultados do estudo indicam que 38,6% das matérias mencionam que a pesquisa divulgada está em processo de avaliação, 27,6% das notícias omitem essa informação e 19,6% fazem menções superficiais ou errôneas. Quanto aos enquadramentos, foram identificadas notícias com ênfase nas crises política e epistêmica, e, em menor proporção, em checagem de fatos e construção crítica e explicativa, sendo que todas elas trazem controvérsias científicas como centro da discussão. Como reflexos desses enquadramentos, observa-se a polarização da ciência entre usuários e manifestações de descrença na ciência e na mídia como comportamentos recorrentes.
Analysis of High School Students’ Errors in Solving Trigonometry Problems

This study examined High School students’ error displayed in solving trigonometry problems. The literature revealed that trigonometry is difficult for students to understand and our paper contends that identifying students’ error and understanding how the errors occurred can serve as a point of reference for instructional decisions which will make the concept easier. The study uses a quantitative research techniques to explore students’ errors in solving trigonometry problems. Ninety students were sampled using multistage sample techniques. Trigonometry Achievement Test (TAT) was used in data collection. Descriptive statistics (figures and tables) was used to present the students’ error after content analysis was carried out and Modified Newman’s Error Hierarchy was used in classifying students’ error. The results revealed most students’ errors occurs at transforming, processing and encoding stages. Independent sample t-test was used to compare the errors committed by male and female students. Independent samples t-test of groups’ differences in means among male and female students indicated that, there was a significant difference in their mean scores at t(89) = 2.198, p < . 05. Thus, female students’ level of committing errors in solving trigonometry problems was significantly higher than their male counterparts. The study recommends that Mathematics teachers should make the teaching of trigonometry practical and more activity-oriented to limit students’ error in solving trigonometry problem most importantly among the female students.
The implementation of early science education in preschool teachers’ initial teacher education. A survey of teacher educators about their aims, practices and challenges in teaching science

ABSTRACT Initial teacher education is the main opportunity to prepare pre-service preschool teachers to foster young children’s science competences. Although initial teacher education is important for preschool teachers’ later instruction in practice, little is known about early science education in initial teacher education. To gather first insights into initial teacher education, this study explored the lesson aims, the frequency of different content taught and teaching methods used, and lessons preparation sources of 72 German teacher educators. In addition, teacher educators reported their challenges regarding their teaching of early science education. Data was gathered by using self-reports. Results revealed that the key lesson aims of teacher educators involved refer to the promotion of pre-service preschool teachers’ motivation and the preparation of the students for implementing science learning experiences in preschools. The teacher educators also reported challenges they faced teaching early science education, which included the students, general conditions, the actual teaching of early science education and teacher educators’ own qualifications. With regard to the teaching practices, we found a high variance in the content knowledge and pedagogical content knowledge taught. Implications for policymakers, professional development providers and initial teacher education institutions are discussed.
