EFFECTIVE MATHEMATICS LEARNING IN TWO AUSTRALIAN PRIMARY CLASSES: EXPLORING THE UNDERLYING VALUES

Mathematics educational research on high performing countries highlights the role of cultural values. This paper reports on the qualitative phase of a project, which aims to identify some of the values underlying effective mathematics learning in the primary classroom, and to explore how these were valued by the teacher and students. Amongst the 13 values negotiated in the six hour-long lessons, ‘example’, ‘sharing’, ‘resources’, and ‘multimodal representations’ were embraced by students across all ability groups. In the negotiation of conflicting values between teachers and their students, it was found that the teacher’s authority and his/her awareness of what s/he values play important roles. WHY THE FOCUS ON VALUES Particular mathematics pedagogical practices of high performing countries in international comparative assessments such as TIMSS and PISA have been known to
Water column stratification structures viral community composition in the Sargasso Sea

A decade-long study of viral abundance at the Bermuda Atlantic Time-series Study (BATS) site recently revealed an annually recurring pattern where viral abundance was fairly uniform in the well-mixed upper water column each winter, yet a subsurface peak in viral abundance between 60 and 100 m depth developed each summer during water column stratification (Parsons et al. 2012; ISME J 6:273–284). Building upon these findings, this study tests the hypothesis that in the well-mixed period (March), the viral communities at the surface and at 100 m depth are similar in composition, while during water column stratification (September), differences in the viruses occupying these 2 depths emerge. Amplification and sequencing of 3 signature genes (g23, phoH, and the ssDNA phage major capsid protein) in addition to randomly amplified polymorphic DNA PCR gel banding patterns were used to assess the structure of viral communities. The 4 data sets revealed similar communities at the surface and 100 m in March when the upper water column was mixed, and divergent communities during September stratification. Water density was found to be a significant driver of viral community variability, with surface communities during September water column stratification sig nificantly different from all other communities. These data demonstrate the im portance of water column stratification for structuring viral community composition at the BATS site, either directly through altering the physical conditions, such as ultraviolet radiation, that the viral communities are exposed to or indirectly through structuring bacterial host communities.

Estimating Dynamic Treatment Effects in Event Studies With Heterogeneous Treatment Effects

Event studies are frequently used to estimate average treatment effects on the treated (ATT). In estimating the ATT, researchers commonly use fixed effects models that implicitly assume constant treatment effects across cohorts. We show that this is not an innocuous assumption. In fixed effect models where the sole regressor is treatment status, the OLS coefficient is a non-convex average of the heterogeneous cohort-specific ATTs. When regressors containing lags and leads of treatment are added, the OLS coefficient corresponding to a given lead or lag picks up spurious terms consisting of treatment effects from other periods. Therefore, estimates from these commonly used models are not causally interpretable. We propose alternative estimators that identify certain convex averages of the cohort-specific ATTs, hence allowing for causal interpretation even under heterogeneous treatment effects. To illustrate the empirical content of our results, we show that the fixed effects estimators and our proposed estimators differ substantially in an application to the economic consequences of hospitalization.
The Determinants of Capital Structure: an Empirical Study of Omani Listed Industrial Companies

This study investigates five determinants of capital structure (leverage) in three subsectors of the Omani Industrial companies (food, construction and chemical) listed on Muscat Securities Market for the period 2008–2012. According to available information and literature review, the determinants are profitability measured by return on assets (ROA), risk measured by the standard deviation of return on assets, the size of the company measured by the natural logarithm of total assets, rate of growth measured by the market-book value ratio (P/E) and assets tangibility measured by fixed assets to total assets ratio. The capital structure or leverage is measured by total debt ratio. In the industrial sector as whole; the findings of the study indicate that there is a statistically positive association between risk and tangibility and leverage. Also, there is a statistically negative association between growth rate and profitability and leverage, while there is no association with size. Regression analysis indicates that size, tangibility and risk have a statistically significant effect on leverage.
Incidence of insidious fruit rot as related to mineral nutrients in Harumanis mangoes (Kejadian reput dalam buah dan kaitannya dengan nutrien galian dalam mangga Harumanis)

A study was conducted to determine the relationships between insidious fruit rot (IFR) and mineral nutrients in mango (Mangifera indica L.) cv. Harumanis. The occurrence of IFR was influenced by fruit size. Bigger fruit was more affected by this disorder which was characterised by a tissue breakdown in the fruit. Nitrogen (N) and calcium (Ca) were found to be most consistently related to IFR. The affected fruit was found to be high in N and low in Ca. Nitrogen and Ca contents in leaves exhibited positive and negative correlation respectively with the incidence of IFR in fruit. The N/Ca ratio in leaves also showed similar correlation as N. However, the N/Ca ratio in leaves was more related to the IFR incidence compared with N or Ca level alone.
Experimental Study of the Effect of Foundation Shape on Settlement and Bearing Capacity of Soils

The paper presents pattern of load-settlement curves of four prototypes of shallow foundations with different vertical crosssectional shapes on three different modeled subsoil conditions. Prototypes of shallow foundations with rectangular, wedge and T-shape vertical cross-sections were studied. The study generally shows that bulk of the load resistance of subsoil bases at the instance of shallow foundations with rectangular vertical cross-sectional shapes is mostly associated with the soil beneath the foundation base, while at the instances of those with wedge and T-shape vertical cross-sectional shape, both soil beneath the foundations’ bases and along their vertical stems, actively participates in the resistance of structural loads. This indicates that using foundations with wedge and T-shape vertical cross-section can help in mobilizing substantial mass of soil above the foundation base, to function not only as surcharge to the soil below the foundation base, but also in resisting loads, and therefore assisting in the distribution of structural loads to less dipper soil strata, especially when stronger soil layers is underlain by weaker ones.

ARDL Approach to Trade Libralisation and Economic Growth in the Developing Country: Evidence from Nigeria

This study examined the trade impact of trade liberalization in the developing economies from 1981 to 2014. It employed the Autoregressive Distributed Lag (ARDL) bound test approach. Two measures of trade liberalization were used to form an index of trade openness, while three measures of financial sector development were used to construct index of financial development using principal component analysis. The result suggested that the long run impact of trade liberalization on the economic growth of Nigerian is found to be negatively significant. The short run impact of trade liberalization on economic growth was found to be positive and significant. In total, the long and short run impact of trade liberalization to economic growth suggested that the Nigeria economy is yet to harness the benefits of international trade. It was also suggested that trade liberalization could enhance economic growth. However, the introduction of other variables in the likes of financial development, labour force and gross capital formation, none played a significant impact on economic growth in the Nigeria. The findings of this study offer some important policy implications. Trade liberalization could be another avenue for economic diversification through foreign direct investment and by so doing there will be improved in gross capital formation and indeed economic growth. Nigeria also needs to create diversified, dynamic and competitive sectors capable of absorbing the more educated labour force to translate human capital to higher economic growth Key Words : Trade liberalization, Economic growth, Labour force, gdpc, ARDL, cointegration
No . 2001-03 Existing and Emerging Regional Trading Arrangements

This study presented selected existing and emerging Regional Trading Arrangements (RTAs) to show key features of the new regionalism and to determine if they help advance the cause of multilateralism. In its assessment, it found that these new RTAs go beyond mere trade in commodities and services and incorporate deeper forms of integration, such as liberalization of investment regimes, adoption of mutual recognition arrangements, and in some instances, harmonization of competition policy. Efforts are made to ensure true integration of national markets. Furthermore, the new RTAs tend to be more outward-oriented than the ones established more than two decades ago. Moreover, a number of them include both developed and developing economies, giving rise to possibilities for greater specialization in production and trade. All these suggest that the new RTAs upon up new opportunities to advance multilateral trade liberalization.
Ultrafast electron dynamics reveal the high potential of InSe for hot-carrier optoelectronics

We monitor the dynamics of hot carriers in InSe by means of two photons photoelectron spectroscopy (2PPE). The electrons excited by photons of 3.12 eV experience a manifold relaxation. First, they thermalize to the electronic states degenerate with the $\bar M$ valley. Subsequently, the electronic cooling is dictated by Fr\"ohlich coupling with phonons of small momentum transfer. Ab-initio calculations predict cooling rates that are in good agreement with the observed dynamics. We argue that electrons accumulating in states degenerate with the $\bar M$ valley could travel through a multilayer flake of InSe with lateral size of 1 micrometer. The hot carriers pave a viable route to the realization of below-bandgap photodiodes and Gunn oscillators. Our results indicate that these technologies may find a natural implementation in future devices based on layered chalcogenides.
Prognostic role of eeg indicators for changes in cognitive performance in patients in the early and long-term postoperative periods of coronary artery bypass grafting

PROGNOSTIC ROLE OF EEG INDICATORS FOR CHANGES IN COGNITIVE PERFORMANCE IN PATIENTS IN THE EARLY AND LONG-TERM POSTOPERATIVE PERIODS OF CORONARY ARTERY BYPASS GRAFTING Federal State Budgetary Institution “Research Institute for Complex Issues of Cardiovascular Diseases”, Kemerovo, Russia Aim To study the prognostic role of background EEG activity indicators recorded in patients in the preoperative period of coronary artery bypass grafting (CABG) for the development of cognitive impairment in the early and late postoperative periods. Methods A total of 85 patients with coronary artery disease (CAD) who underwent CABG were included in the study. Before CABG (3-5 days) all neuropsychological testing and EEG studies were performed, at the 7-10th days and 1 year after CABG only neuropsychological testing. EEG predictors of early (n = 85) and long-term (n = 65) postoperative cognitive dysfunction were detected using the method of multiple linear regression. Results EEG predictors of deterioration of cognitive status in the early postoperative period of CABG were basic higher values of theta-rhythm power in the posterior regions of the cortex of both hemispheres with closed and open eyes. Whereas higher preoperative parameters of beta2-rhythm biopotentials in the left frontal areas with eyes open and lower alpha-rhythm power in the left occipital parts of the cerebral cortex with eyes closed were associated with long-term postoperative cognitive dysfunction. Conclusion Associations of preoperative EEG indicators with deteriorations of cognitive status in the early and longterm postoperative periods of CABG were revealed.
Application of Grey Relational Analysis to Determine Key Factors for Performance Measurement of Taiwan High Speed Rail Service Quality

In this paper, the balanced scorecard (BSC) is used to establish an effective performance measurement of Taiwan High Speed Rail (HSR) service quality, and then the grey relational analysis is used to determine key factors for performance measurement of Taiwan HSR service quality and the importance-performance analysis (IPA) is used to analyze HSR passenger service quality in a satisfactory condition. The results show that HSR passenger exhibit a performance and willingness to spend more money in exchange for saving time; thus, it is good to pay attention to punctuality, safety, and comfort. In addition, if the policy of HSR can provide preferential fares to passengers, it will be able to increase passenger satisfaction and loyalty. This way, passengers are willing to continue spending, bringing substance to enhance the profitability of HSR.
Which One to Choose? Evidence on the Choice and Success of Job Search Methods*

This paper empirically investigates the determinants of the choice of six di erent job search channels and the job search intensity, and the resulting success in terms of employment uptake of the job seeker. The channels comprise the public employment agency, advertisements in newspapers and journals, internet job search, recruitment agencies, direct applications, and personal contacts. In line with the ndings for other countries, the results show that consideration of a larger number of channels raises the employment chances. The estimates of the determinants exhibit speci c patterns for the choice of the single channels and the level of search intensity. The results of success of the job search channels reveal that the public employment agency is ine ective and harms the employment chances of the unemployed job seekers. In contrast, direct applications for jobs increase the employment chances.
ROLE OF TELEVISION IN AGRICULTURAL TECHNOLOGY TRANSFER

Nothing seems more important in agricultural development than the dissemination of latest agricultural technologies among the farmers. Agricultural extension organizations are entrusted with this primary task for which they use a variety of extension teaching methods/media. Television is one of the media being used for this purpose both by public and private sectors The present paper aims to assess the role of television In agricultural technology transfer. The data show that majority of the respondents was unaware of the regular agricultural telecasts Only 5.60% respondents were found to be regular viewers and they preferred watching agricultural telecasts over other assignments. Feedback link between farmers and TV authorities appeared to be totally missing. Majority of the respondents watched agricultural telecasts rarely. a reason able number was occasional Viewers, and only a fraction of the respondents was regular viewers A vast majority got only up to 25% agricultural information through agricultural telecasts, 128% got 25-50% information while those who got more than 50% information were negligible in number
Perceived Family-Supportive Work Culture, Affective Commitment and Turnover Intention of Employees

The objective of this research is to examine the role of perceived family-supportive work culture in reducing turnover intention of employees and the mediating role of affective commitment in the relationship between perceived family-supportive work culture and turnover intention. The subjects in this study constituted 693 employees from 20 private service organizations in the Klang Valley, Malaysia. Results of multiple regression analyses indicate that perceived family-supportive work culture is positively related to turnover intention of employees and employees' affective commitment mediate the relationship between perceived family-supportive work culture and turnover intention. The results imply the need for employers to understand how employees view the family-friendly programs in terms of the support provided and the values they place on the programs as captured in perceived family-supportive work culture. Positive perceptions would help reduce turnover intention as well the affective commitment of employees. (Aminah Ahmad, Zoharah Omar.

The Relationships Between Laying Age and Repeatability of Egg Quality Traits in Japanese Quails (Coturnix coturnix japonica)

Repeatability at 12, 16, 20, 24 and 28-weeks of age of egg weight, egg length, yolk weight, albumen weight, shell thickness, shell membrane thickness, albumen index, yolk index, egg index and shape index was estimated based on the first three eggs laid in the week by forty-eight Japanese quail (Coturnix coturnix japonica) pullets. The estimated repeatability for these traits was high (0.58 0.99) with a consistent increase in repeatability as laying age progressed. Repeatability of egg length, egg index and shape index showed a linear relationship with age, where as the remaining traits showed a curvilinear relationship. The general increase in repeatability of each trait with age indicates that fewer records would be required to adequately characterize the inherent producing ability of each quail hen for the trait as laying age progressed. Maximum repeatability estimates were observed at 28 weeks of age.
A Statistical Analysis of Wind Speed and Power Density Based on Weibull and Rayleigh Models of Jumla, Nepal

In the present study, wind speed data of Jumla, Nepal have been statistically analyzed. For this purpose, the daily averaged wind speed data for 10 year period (2004-2014: 2012 excluded) provided by Department of Hydrology and Meteorology (DHM) was analyzed to estimate wind power density. Wind speed as high as 18 m/s was recorded at height of 10 m. Annual mean wind speed was ascertained to be decreasing from 7.35 m/s in 2004 to 5.13 m/s in 2014 as a consequence of Global Climate Change. This is a subject of concern looking at government’s plan to harness wind energy. Monthly wind speed plot shows that the fastest wind speed is generally in month of June (Monsoon Season) and slowest in December/January (Winter Season). Results presented Weibull distribution to fit measured probability distribution better than the Rayleigh distribution for whole years in High altitude region of Nepal. Average value of wind power density based on mean and root mean cube seed approaches were 131.31 W/m2/year and 184.93 W/m2/year respectively indicating that Jumla stands in class III. Weibull distribution shows a good approximation for estimation of power density with maximum error of 3.68% when root mean cube speed is taken as reference.
LONG-TERM DROUGHT VARIABILITY AND TRENDS IN BARCELONA (1787-2014)

Long-term drought variability and trends were assessed in Barcelona at annual and seasonal scale for the period 1787-2014 and sub-periods 1851-2014, 1901-2014 and 1951-2014 to identify changes in drought patterns across time. High quality and adjusted monthly temperature and precipitation series were required for this purpose. The Standardized Precipitation Index (SPI), based on precipitation, and the Standardized Precipitation Evapotranspiration Index (SPEI), based on the difference between precipitation and reference evapotranspiration (ET0), were calculated to describe temporal drought fluctuations. Therefore, major droughts and wet events were identified and an accurate analysis of drought severity, magnitude and duration were also carried out. Both drought indices provided similar results related to drought variability and trends in Barcelona across time, although the SPEI showed larger drought severity than SPI especially during the second half of the 20th century. Trends analysis revealed a significant drying trend at annual scale according to the SPEI since mid-19th century while the SPI did not show changes in drought patterns. At seasonal scale, both the SPI and SPEI found a clear drying trend only for summer (JJA) during the current period (1951-2014), although the SPEI was indicating the trend towards drier conditions for the whole period (1787-2014). Drought severity in SPEI series increased 13% during the second half of the 20th century compared with the whole period under study while drought magnitude and duration did not present significant changes in both the SPI and SPEI series. The increasing atmospheric evaporative demand associated to the large temperature rising experienced in Barcelona during the last decades could have played a substantial role in explaining the increase of drought severity and trends found in the SPEI series.
