THE DIFFICULTIES OF HIGH SCHOOL STUDENTS IN SOLVING HIGHER-ORDER THINKING SKILLS PROBLEMS

International surveys, such as TIMSS and PISA, frequently put Indonesia in the low ranks. It is an indication that the higher-order thinking skills (HOTS) of students in Indonesia are still low. This research aims to analyze students’ difficulties in solving problems that measure HOTS. This is a case study research with a qualitative approach. Participants studied were 93 high school students in grade XI. Data were collected using test instruments that measure HOTS, which was developed based on the standard contents of high school mathematics. The difficulties were analyzed descriptively by observing students’ errors in answering HOTS test items. Students’ errors were classified based on Newman’s Error Procedure (NEP). The result shows that around 8.33% of the students had difficulties in comprehension, 15.59% in transformation, 32.53% in process skills, and 1.34 % in encoding. Keywords: HOTS problem in mathematics, students’ difficulties, case study, Newman’s error procedure.
Cross-Industry Information Sharing among Colleagues and Analyst Research

We identify a specific organizational resource in brokerage houses—information sharing among analyst colleagues who cover economically related industries along a supply chain. We hypothesize that this resource constitutes a knowledge asset that benefits analyst research and allows analysts to have a higher level of industry specialization. The impact of this resource depends on colleagues’ information complementarity, which we measure using the level of economic connection between an analyst’s industry and her colleagues’ industries. Controlling for economic determinants and brokerage selection effects, we find that colleagues’ information sharing improves the analyst’s earnings forecast accuracy, stock recommendation profitability, and investor recognition. We show that the colleagues’ coverage of downstream (upstream) industries improves the analyst’s revenue (expense) forecasts. We find that information sharing among colleagues allows analysts, especially less capable ones, to cover a more specialized research portfolio. Overall, our findings align with the theory of the firm that a firm’s organizational structures contribute to employee performance and specialization.
Public Culture A United States and Asia Comparison: The Role Emotion Display Migrant Labour of Performance Individual (Evidence from Indonesia)

This study explores the relationship between emotional immigrant labor and burnout in the context of individualist versus collectivist culture. Based on immigrant labor samples working in the United States and in east and central Asian countries, the results show that: (1) Migrant labor emotions that pretend are positively related to burnout in individualist culture and collectivism. (2) The othentic Migrant labour emotions are negatively related to burnout of individualist culture and collectivism. (3) Emotional pretensions are positively related to individual performance in the culture of collectivism. (4) There is no difference in the relationship between emotional appearance and performance in individualist culture and collectivism. (5) Working for an individualist culture company is more likely to cause burnout than a culture of collectivism. This finding shows the differences in eastern (Asian) and western (American) cultures, but the view of culture is dynamic.
Songbird ventral basal ganglia sends performance error signals to dopaminergic midbrain

Ventral tegmental area (VTA) dopamine neurons signal prediction error, the difference between actual and predicted outcome, but it remains unclear how error is computed. Here we identify in songbirds a ventral basal ganglia (vBG) region that is required for song learning and that sends prediction error signals to VTA. During singing, vBG neurons heterogeneously encoded song timing, auditory error, predicted error, and the difference between the two (prediction error). Viral tracing revealed inputs to vBG from auditory and vocal motor thalamus, auditory and vocal motor cortex, and VTA. Our findings reveal a classic actor-critic circuit motif in which a ventral critic learns the ‘prediction’ component of a prediction error signal that is relayed by VTA to a dorsal actor (the vocal motor BG nucleus Area X). A circuit motif for computing reward prediction error can compute predicted performance quality during motor sequence learning.
CO-REGULATION PROCESSES WITHIN INTERACTIVE DYNAMICS: INSIGHTS FROM SECOND GRADERS’ COOPERATIVE WRITING

This research aims at analyzing the features of interactive dynamics in second graders’ peer interactions (age 7-8) during cooperative writing in classroom settings. Focused on in-depth qualitative analyses of videotaped data, four pupil pairs’ interactions have been examined in light of three dimensions: social, cooperative and cognitive. Within two main types of dynamics (favoring vs. not favoring learning), conjectures have been drawn about co-regulation processes in peer learning. While negative dynamics have shown to be detrimental for the cognitive processing of the task, thus needing teacher contextual regulation, positive dynamics have revealed three forms of teamwork, labelled self-reliant, autonomous and dependent. The results show that young learners, even when engaged in positive dynamics, are not always able to co-regulate peer learning. These findings call for teacher’s careful observation in order to scaffold learners’ cognitive processing. Keywords: collaborative writing, cooperative learning, interactive dynamics, learning processes, qualitative analysis.
Perennial C4 grasses increase root biomass and carbon in sown temperate pastures

ABSTRACT The addition of perennial warm-season C4 grasses to perennial pastures, may contribute to carbon sequestration, in addition to increasing production and stabilising seasonal variations. We quantified root biomass in three pasture mixtures after 3 years of growth: a conventional mixture of Festuca arundinacea, Trifolium repens and Lotus corniculatus, the conventional mixture + Paspalum notatum and the conventional mixture + Paspalum dilatatum. Root biomass and content of carbon were higher at 0–10 cm than at 10–30 cm depth for both summer and winter sampling dates in all samples. Mixtures with Paspalum had higher root biomass than the conventional mixture in summer. No differences were observed between the two species of Paspalum in root biomass or carbon. These results show that the inclusion of Paspalum species in these systems may potentially increase carbon soil carbon, although further research is required to evaluate the effect of other management practices.
Size dependence of Peltier cooling in ferromagnet/Au nanopillars

We study Peltier cooling in current-perpendicular-to-plane multilayer nanopillars with diameters D varying from 60 to 430 nm and made from Au and various ferromagnets (FMs): Heusler compounds Co2MnSi and Co2FeSi (CFS) and conventional FM metals Fe and Co. We report an enhanced effective Peltier coefficient ΠCPP in resistance–current curves at small D (<120 nm). The maximum ΠCPP value of about 165 mV, found for the CFS/Au interface with D ∼ 60 nm, is 24 times higher than the bulk Peltier coefficient Πbulk (∼7 mV) and corresponds to a high cooling power of 43.6 MW/cm2.
Prevalence and phenotypic antibiotic bioassay of methicillin-resistant Staphylococcus aureus in raw meats sold at various retail outlets in the cape coast metropolis of Ghana.

MRSA is an emerging zoonotic organism that has gained attention in public health because of their disease causing abilities. They have been implicated in most food contaminations and foodborne infections. Despite these importance’s, little is known on the MRSA situation in the meat consume in the Cape Coast Metropolis of Ghana. This study assessed the MRSA prevalence in meat sold at various retail outlets in the Cape Coast Metropolis. One hundred meat samples were obtained from pigs, chicken, cattle and goats from various retail points in the Metropolis. The total viable count, MRSA isolation and antibiotic susceptibility profiles of the isolates were performed following standard procedures. Overall, a prevalence of 45% (45/100) MRSA isolates was phenotypically detected in this study. Although the sample sizes were different, pork recorded the highest MRSA isolates of 47.6% (20/42). Sixteen (16) out of 45 MRSA isolates were Multi-drug resistant. All the isolates were resistant to all the antibiotics used except for Vancomycin. The prevalence of MRSA isolates in raw meat in most of the retail outlets in this study gives a warning signal for possible occurrence of food borne infections capable of producing outbreaks in the district.
Invasion and Parasite Subsistence of Human Cancer

Cancer War against the current biggest threat to global human health (1971 2xxx) failed dismally because the bankruptcy of its theoretical bases. New insights in cancer biology and origin are sorely needed. The goal of this article is to create the most exhaustive presentation of entirely different hypothesis of xenogamous origin and parasite subsistence of human cancer. Cancern is the genomic parasite spread via intrusion of its causative agent in the genome of affected organism. This article aids the most exhaustive search of the hypothesis evidence. The investigation was based on a multidisciplinary integrative reassessment and reinterpretation of relevant current data about cancer. The main focus was on the consecutive stages of cancer subsistence, beginning from the invasion of victim's genome with cancerous gamete and finishing by sexual transmission of cancerous genome between people. The subsistence of cancer at the expense of substances derived from the body of its prey is crucial for the progression of cancer within the host's body. The subsistence is also supported by the inherent possession by the cancer cells of constitutive immunity to the host's immune defense and cell regulation. These new notions provide framework and landmarks for the location of genomic roots of cancer and encourage new proposals for cancer prevention by voluntary restriction of cancerous fertilization with orientation on non-cancerous genealogies.
Graduates’ Continuing Work as Scholarly Practitioners after Participation in a Carnegie Project on the Education Doctorate Guided, EdD Program

Aim/Purpose This paper examined whether, and how, graduates of an EdD program continued to (a) engage in scholarly practitioner efforts and (b) employ inquiry skills in their workplace settings after completion of their doctoral studies. Background Little research has been conducted on follow-up of graduates of doctoral programs. The limited research that has been done, typically, was conducted to examine employment status and satisfaction, salary, and adequacy of preparation. Generally, studies have not explored the effects of graduates’ preparation on subsequent use of the skills. Methodology A mixed method study was conducted. In all, 67 graduates completed an online questionnaire (~52% response rate) assessing their efforts with respect to using scholarly practitioner skills and inquiry skills. Eleven of the graduates were interviewed and these data were used to examine more closely graduates’ use of these skills. Graduates worked in various K-12, community college, university, and other education-related settings. Contribution This study begins to fill the gap that exists with respect to examining the effects of graduates’ preparation on subsequent use of those skills. In particular, the study was conducted to examine whether and how program graduates continued to use scholarly practitioner and inquiry skills developed during their doctoral preparation in their subsequent professional work. Findings The quantitative and qualitative data indicated graduates continued to act as scholarly practitioners and engaged in inquiry skills. The interview data were particularly robust and replete with examples of how graduates used these skills/abilities in their workplaces. Graduates’ Continuing Work as Scholarly Practitioners 804 Recommendations for Practitioners EdD programs that provide affordances for students to apply skills as scholarly practitioners and employ inquiry as practice methods during students’ preparation will foster skills/abilities that can be applied in subsequent professional practice by educators after graduation. Recommendation for Researchers Additional studies of graduates’ application of skills/abilities learned in doctoral programs are warranted because of the limited research that has been conducted in this area. Impact on Society Developing educators’ scholarly practitioner skills and inquiry as practice methods will allow educators to more effectively attack the problems of practice they encounter on a daily basis and improve the educational situations of those they teach and serve. Future Research A likely next step would be to explore the use of scholarly practice skills and inquiry skills using a case study approach to examine more closely how educators apply these skills/abilities in daily practice.
Characterization of Brazilian Northeastern plastic clays

Abstract Plastic clays are one of the main raw materials used in ceramic technology. However, there is a shortage of good quality plastic clays in the world for use in porcelain technology. The aim of this study was to characterize plastic clays from Northeastern Brazil. Chemical and mineralogical composition, particle size distribution, plasticity and green strength of the clays were determined. The analyzed clays were predominantly composed of kaolinite and quartz, and some contained smectite. The amount of iron oxide in the clays was higher than 1.0% and for some of them the values were higher than 3%; the liquid and plastic limits ranged from 22% to 48% and 10% to 32%, respectively. According to characterization data, three plastic clays had potential to be used as alternative ball clay, due to their plasticity and mineralogical characteristics.

This study was meant to describe job satisfaction of elementary school teachers of Boven Digoel district, Papua, and how it predicts their job performance. To do so, we applied a survey research. Two survey questionnaire were self-administered to 352 teacher-respondent which were incidentally drawn from amongst 412 elementary school teachers of Boven Digoel district, Papua. Derived data were examined statistically using simple linear regression analysis method by utilizing Statistical Package for the Social Sciences (SPSS) version 21. Result of data analysis showed that job performance of elementary school teachers of Boben Digoel district is significant positively predicted by their job satisfaction. Finding of this study may be imperative for the school management and education administrator at the regional authority to make paramount efforts of creating valuable plans for enhancing teacher’s satisfaction in order to promote a better job performance of elementary school teachers of Boven Digoel district, Papua.
Effects of oil extracts from Arachis hypogea on stem cell factors for follicular maturation and implantation in the superovulated rat

Oil extracts from Arachis hypogea is often used clinically for the administration of exogenous hormone during assisted reproduction. But its capacity to induce follicular growth after fertilisation to maintain the formation of progesterone has not yet been clarified. We assessed the effects of peanut oil on stem cell factors (SCFs) for follicular maturation and meiotic activities in the superovulated rat. Female rats were superovulated and treated with peanut oil (S + Pn), while the controls were either superovulated and treated with saline solution (S + N), or non-superovulated and treated with saline solution (N) or peanut oil (Pn). After mating, uterine horns and ovaries were obtained and a morphometry of granulosa cells and theca interna (TI) was carried out. The mitotic index (MI) of the granulosa cells and the protein expression of SCF on ovarian stromal cells were evaluated, as well as the ultramorphology of the endometrium. Results showed a successful implantation in S + Pn, N and Pn groups. The MI was high in the Pn group, moderate in the S + Pn and N groups, and poor in the S + N group. However, both follicular size and TI levels varied significantly (p < 0.05) across intervention groups. In multiple comparisons, both follicular size and TI values in the experimental group were the highest (p < 0.0001). Protein expressions of SFC were high on ovarian stromal cells in both the S + Pn and N groups, while decidualisation was observed in the experimental groups. We conclude that peanut oil may be implicated in mitotic activities of granolusa cells, induce the release of SCF and sustain implantation.
THE IMPACT OF DESTINATION IMAGE ON DESTINATION RECOMMENDATION

Increasing tourism expenditures play important role in the economies of countries especially developing ones. Therefore destinations which want to attract more tourists should consider what factors affect people’s travel decision-making process. Destination recommendation is one of the most efficient noncommercial information sources on travel decision-making process. The impact of destination recommendation on travel decision is important as much as the factors that construct the destination recommendation. It is considered that destination image, which is one of the most efficient determinant on destination choice process, has an effect on destination recommendation. Thus, in this research the impact of destination image on destination recommendation is investigated through foreign visitors who traveled to Cappadocia, Turkey. The research result show destination image affects destination recommendation. http://dx.doi. org/10.17130/ijmeb.2019456406
VRC01 provides sterilizing protection to non human primates from mucosal SHIV challenges (155.11)

VRC01 is an exceptionally broad neutralizing monoclonal antibody targeting the CD4 binding site of HIV gp120. It was isolated from an HIV-1 infected donor and is able neutralize over 90% of circulating HIV-1 isolates at high potency in vitro. Using a nonhuman primate lentiviral immunodeficiency virus infection model, we assessed the ability of VRC01 to protect animals from mucosal challenge with a pathogenic chimeric simian-human immunodeficiency virus (SHIV). The animals were first administered either VRC01 or a control IgG i.v. at a dose of 20 mg/kg and 2 days later were mucosally challenged with SHIV. We used two different mucosal routes - intrarectal (i.r.) and intravaginal (ivag) for mucosal challenge to mimic natural HIV exposures in humans. The plasma viral loads and sera VRC01 levels in animals were measured weekly by real time RT-PCR and ELISA, respectively. We observed that 3 out of the 4 animals in both the control groups were infected, with peak viremia occurring at week 2 for the i.r. challenge and at week 3 for the ivag challenge. In contrast, none of the 4 animals that received VRC01 got infected in both mucosal challenge groups (p=0.04). These results demonstrate that a broadly neutralizing CD4 binding site mAb, VRC01, protects against mucosal exposure to pathogenic viruses in vivo. This finding provides support for the CD4 binding site as a target of AIDS vaccine development and the possible use of VRC01 to prevent mucosal transmission of HIV-1 in humans.
PARTIAL LEAST SQUARE ANALYSIS ON MICRO ENTERPRISES’ INTELLECTUAL CAPITAL AND PERFORMANCE: THE MEDIATING EFFECT OF TACIT KNOWLEDGE SHARING

Micro enterprises formed the majority of business establishments in Malaysia and play an important role in the business ecosystem. There are numerous studies of intellectual capital on large organizations and small and medium enterprises, however no study has been carried out on micro enterprises. The findings of the partial-least square analysis of one hundred and six micro enterprises found that intellectual capital has a significant relationship to organizational performance. In addition, the relationship between intellectual capital and organizational performance was significantly influenced by tacit knowledge sharing. In particular, tacit knowledge sharing proves to be extremely relevant when it comes to reinforcing the intellectual capital on the performance of micro enterprises in Malaysia. Limitations and implications for future studies are discussed.
Analysis of genetic diversity and bioaccumulation potential of Juncus acutus grown in some northern swamp habitats of Egypt

Juncus acutus is one of main wetland plants, valuable in remediation of wetland environment from heavy metals. Determination of genetic diversity in its natural populations is important for species conservation and ecological restoration. The present study evaluated the genetic diversity of four populations of J. acutus growing in Manzala lake coast and inland swamps in Ismailia and Sinai by using random amplified polymorphic DNA (RAPD) technique. Fifteen primers generated a total of 217 RAPD bands (loci) of which 156 (71.9%) were polymorphic across all individuals of the four populations. At Manzala lake coast (i.e. sites 3 and 4, contaminated sites), the genetic diversity measures observed in the populations of the two species showed higher diversity in comparison to the less contaminated sites 1 and 2 ( Ismailia and Sinai). This study revealed also the presence of a noticeable accordance between genetic diversity measures of J. acutus with some edaphic variables and heavy metal concentration in soil of the studied sites and leaves of the two species and it indicated that populations from sites 3 and 4 respond with increased genetic variation, resulting possibly from new mutations affecting allele frequencies, as a consequences of adaptation to changes or disturbances in the environment. This may indicate that the increased diversity levels may act as a buffer to severe heavy metal stress, which explains the importance of monitoring the genetic diversity of J. acutus populations in detecting trends that should alert ecologists to potential problems.
THE DETONATION BEHAVIOR OF AMMONIUM PERCHLORATE AS A FUNCTION OF CHARGE DENSITY AND DIAMETER

Abstract : The detonability limits and detonation behavior were studied for a finely ground ammonium perchlorate (AP). The typical finite diameter D vs rho sub o curve is non-linear and exhibits a maximum in detonation velocity. The failure curve d sub c (diameter) vs rho sub c (critical density) shows a monotonic increase in d sub c with rho sub c in the range rho sub o 1.0 g/cc and is opposite in trend to that for TNT.
Adjusting weight growth curve of male quails Coturnix japonica reared in the semi-arid region of the State of Pernambuco

This study adjusted different regression models to describe the growth pattern of meat quails from birth to 42 days of age. Data of 300 male quails were used. Weight and height information of all quails were collected weekly from the 1st to the 42nd day of age. Body weight of poultry was subjected to the polynomial, logistic, Gompertz, Weibull, and log-normal regression models. The criteria used to choose the best model to explain the growth curve of quails were the coefficient of determination of the model, Akaike’s information criterion, sum of squared residuals and Willmott’s index. For all the models used, the variables age and height were significant to explain the weight of quails. The polynomial (R² = 99.99%, AIC = 24.68, SSR = 27.5, d = 0.9999) and log-normal (R² = 99.60%, AIC = -17.5, SSR = 107.15, d = 0.9989) models presented the best fit criteria and were recommended to explain the growth of quails.
