A 24 GHz hydrology radar system capable of wide‐range surface velocity detection for water resource management applications

We demonstrate a 24 GHz hydrology radar system. The continuous‐wave Doppler radar is capable of noncontact and wide‐range surface‐flow velocity detection in various scenarios. The radar receives the reflected echo signal through a directional narrow‐beam antenna. After amplification and demodulation by the proposed low‐noise amplifier and the subharmonic down‐conversion mixer, respectively, the Doppler frequency‐shift is analyzed by the digital signal processing (DSP) module for estimation of the water flow velocity. Moreover, for water level detection, a phase‐locked loop with micro control unit (MCU)‐controlled division ratio is included in the RF module for generating a stable and tunable (or frequency modulation) 24‐GHz‐band transmitting signal with low phase noise. To verify the radar system, outdoor field tests have been conducted. The measured results are consistent with the theoretical values, and the results of both the float method and the commercial handheld (Stalker Pro II) surface velocity radar. In the condition of water ripple lower than 3 cm, the radar functions well for flow speed range of 0.3 ~ 34.6 m/s. Overall, the hydrology radar is suitable for surface‐flow velocity detection (especially in bad weather) and water resource management (such as water‐level detection).

The need to disentangle assessment and feedback in higher education

ABSTRACT In contemporary higher education systems, the processes of assessment and feedback are often seen as coexisting activities. As a result, they have become entangled in both policy and practice, resulting in a conceptual and practical blurring of their unique purposes. In this paper, we present a critical examination of the issues created by the entanglement of assessment and feedback, arguing that it is important to ensure that the legitimate purposes of both feedback and assessment are not compromised by inappropriate conflation of the two. We situate our argument in the shifting conceptual landscape of feedback, where there is increasing emphasis on students being active players in feedback processes working with and applying information from others to future learning tasks, rather than regarding feedback as a mechanism of transmission of information by teachers. We surface and critically discuss six problems created by the entanglement of assessment and feedback: students’ focus on grades; comments justifying grades rather than support learning; feedback too late to be useful; feedback subordinated to all other processes in course design; overemphasis on documentation of feedback; and the downgrading of feedback created by requirements for anonymous marking. We then propose a series of strategies for preserving the learning function of feedback, through models that give primacy to feedback within learning cycles. We conclude by offering suggestions for research and practice that seek to engage with the challenges created by the entanglement of assessment and feedback, and that maintain the unique purposes of assessment and feedback.
Digitizing the grey areas in the Nigerian public procurement system using e-Procurement technologies

Abstract The importance of public procurement can be perceived through the opening up of cities, provision of critical infrastructure, leading to the improvement of the quality of life of the citizens. However, the success of public procurement in the provision of fixed infrastructure is at the detriment of grey areas that corrupt public officials use as loopholes to embezzle public funds. Therefore, this study was aimed at examining the grey areas that exist in the public procurement process with a view to identifying the appropriate digital solutions available in e-Procurement technologies. The study utilized a research survey approach using a questionnaire instrument directed at six (6) geopolitical zones in Nigeria. Using a two-stage sampling technique, 759 construction stakeholders with actual knowledge on the use of e-Procurement technologies and public sector procurement participated in the study. The study identified e-Procurement tools and technologies used by construction stakeholders to announce/notify, exchange project information, conduct tendering and submission of a proposal, notification on the award of contract, monitor the progress of work, and make/receive payment for work done in the public procurement sector. This study showed the significant grey areas of procurement processes that need digitalization using e-Procurement technologies to eradicate corrupt behavior/tendencies. The digital divide in public procurement can be reduced, and proper accountability of public funds using digital solutions. The study showed the digital solutions used for public procurement by construction stakeholders in the Nigerian public procurement industry.
DOES SIZE MATTER? A CRITICAL REVIEW OF META-ANALYSIS IN AGRONOMY

SUMMARY Intended to test broad hypotheses and arrive at unifying conclusions, meta-analysis is the process of extracting, assembling, and analyzing large quantities of data from multiple publications to increase statistical power and uncover explanatory patterns. This paper describes the ways in which meta-analysis has been applied to support claims and counter-claims regarding two topics widely debated in agricultural research, namely organic agriculture (OA) and conservation agriculture (CA). We describe the origins of debate for each topic and assess prominent meta-analyses considering data-selection criteria, research question framing, and the interpretation and extrapolation of meta-analytical results. Meta-analyses of OA and CA are also examined in the context of the political economy of development-oriented agricultural research. Does size matter? We suggest that it does, although somewhat ironically. While meta-analysis aims to pool all relevant studies and generate comprehensive databases from which broad insights can be drawn, our case studies suggest that the organization of many meta-analyses may affect the generalizability and usefulness of research results. The politicized nature of debates over OA and CA also appear to affect the divergent ways in which meta-analytical results may be interpreted and extrapolated in struggles over the legitimacy of both practices. Rather than resolving scientific contestation, these factors appear to contribute to the ongoing debate. Meta-analysis is nonetheless becoming increasingly popular with agricultural researchers attracted by the power for the statistical inference offered by large datasets. This paper consequently offers three suggestions for how scientists and readers of scientific literature can more carefully evaluate meta-analyses. First, the ways in which papers and data are collected should be critically assessed. Second, the justification of research questions, framing of farming systems, and the scales at which research results are extrapolated and discussed should be carefully evaluated. Third, when applied to strongly politicized topics situated in an arena of scientific debate, as is the case with OA and CA, more conservative interpretations of meta-analytical results that recognize the socially and politically embedded nature of agricultural research is are needed.
Effects of different types of imperfect advance demand information in production systems

ABSTRACT One strategy to reduce inventories and increase on-time delivery is to use Advanced Demand Information (ADI) in which customers place their orders ahead of their due date. ADI can be divided into perfect or imperfect information. Under perfect ADI, customers send accurate demand information to the suppliers, specifying exact quantities and due dates. Under imperfect ADI, customer orders’ quantities and/or due dates may change over time or order cancellations may occur. This research focuses on the effects of three types of imperfect ADI on different production systems: changing due dates, changing order quantities, and cancellations. Three different model variations simulate a pull system, a push system, and a hybrid system. We found that only cancellations and changing order quantities had a significant effect on system performance. Generally, the pull and the hybrid system behaved similarly and proved to be more suitable for managing imperfect ADI than the push system.
Finance‐Inequality Nexus: The Long and the Short of it

Although the existence of a link between financial development and income inequality is generally accepted, the relationship between the two is neither theoretically unambiguous, nor empirically uniform. We make a case for distinguishing between the short- and long-term effects of finance on inequality and investigate the nexus in 21 OECD countries over the period 1870-2011. Whilst in the short-run an improvement in financial development tends to reduce inequality, in the long-run, more finance contributes to more inequality. The short-run effect is in line with theories advocating that financial development increases accessibility and availability of financial services, primarily for the poor. The long-run effect suggests that any short-term financial gains of the poor turn are ultimately overwhelmed by the financial gains of the wealthy. We estimate that the short-run effect becomes nil within a few years of a positive innovation to the level of financial development. Strikingly, the only variable to reduce inequality over the short- and long-run is education, which may in part be proxying for financial literacy. Results suggest that policies aimed at reducing inequality through improving access of the poor to finance need to be carefully designed to ensure longevity of impact.

Genetic variability and correlation studies in greengram (Vigna radiata L. Wilczek)

The present experiment was carried out during Kharif2016 to assess the genetic variability and correlation among yield and yield attributing characters of mungbean. Thirty six mungbeangermplasm were investigated for this study for 10 quantitative characters viz., days to 50% flowering, plant height (cm), number of primary branches per plant, number of clusters per plant, number of pods per cluster, number of pods per plant, pod length (cm), number of seeds per pod, 100 seed weight (g) and seed yield per plant (g). On the basis of genetic variability study all the characters exhibited high heritability coupled with high genetic advance, indicating the preponderance of additive gene action. Selection based on this trait will be fruitful. Phenotypic correlation is higher than the genotypic correlation for all the characters under study. From the correlation studies, seed yield per plant showed positive significant correlation with the traits viz., number of pods per plant, number of clusters per plant and number of pods per cluster. Hence, simultaneous selection for the above traits would be more rewarding to bring improvement in mungbean.

Evaluation of Increasing Levels of Phytase in Diets Containing Variable Levels of Amino Acids on Male Broiler Performance and Processing Yields

SUMMARY The objective of the current study was to evaluate the influence of increasing levels of phytase with 3 levels of amino acids (AA) on performance and breast yield. The experiment was arranged as a 3 × 3 factorial ANOVA with of 3 levels of phytase at 500, 1,500, and 3,000 FTU/kg, and 3 AA densities. The first level of AA density represented a typical industry diet that met breeder recommendations (100%) with a 5 (95%) and 10% (90%) reduction for a total of 9 treatments. Each treatment included 7 replicate pens with 45 Cobb 500 males placed per pen. On day 45, 5 broilers per replicate pen were processed to determine cut yields. The inclusion of superdoses (1,500 and 3,000 FTU/kg) of phytase increased (P
Informal Effect of The Biographical Film on The Views of Prospective Science Teachers on Nature of Science

In this study, the effects of a documentary and a biographical film, which was watched in an informal environment, on the prospective science teachers’ nature of science (NOS) views were examined. The study conducted according to the mixed research methodology. The data were obtained through the open-ended questionnaire prepared by considering the consensus aspects of the NOS. The participants were shown a documentary-style biographical film about a cross-section of the life of a famous scientist. The findings show that there are changes in the participants' views on some of the consensus aspects of the nature of science. Some of these were in the desired direction, but the retention was weak. Also, some of the changes are in an undesirable direction such as to create a science myth. According to the results, it can be thought that films adapted from the history of science can be used to teach the nature of science. Since films produced for different purposes such as art and entertainment may cause problems in teaching the nature of science, it can be suggested to use such films in a more structured learning environment.
A Qualitative Investigation Into the Impact of the Basketball Learning Intervention Programme (BLIP) on Disengaged Secondary School Students in the United Kingdom

This paper will evaluate the longitudinal effects of a basketball based intervention programme that targeted ten disengaged male secondary school students at a school in the Kent, England. The programme aimed to improve the behaviour and academic performance of the participants through a weekly intervention carried out by an external basketball player and coach providing academic support, mentoring and specially designed basketball sessions. Sports interventions have been deemed to provide a positive short-term impact on young people. However, researchers have identified the need for a longitudinal approach in order to examine the effects of such interventions post involvement as supported. This study involved five former Basketball Learning Intervention Programme (BLIP) members (with a mean age of 16.4 SD± 0.55 years) that were interviewed using semi-structured interview approach, 12 months after completing the intervention. Interpretative Phenomenological Analysis (IPA) revealed four superordinate and eleven subordinate themes. The four supeordinate themes were; ‘baseline behaviours pre-intervention’, ‘immediate outcomes of the BLIP’, ‘impact of the coach’ and ‘long standing transferable outcomes’. The results revealed an immediate impact in comparison to the baseline behaviours of the participants pre-intervention. The data suggested that one of the most effective aspects of the programme was the positive impact of the coach on the participants. More importantly, this is the only study to report long-term improvements amongst the participants in terms of behaviour and academics as a result of engagement in a sports based intervention.
Understanding the Aerodynamic Behavior and Energy Conversion Capability of Small Darrieus Vertical Axis Wind Turbines in Turbulent Flows

Small Darrieus vertical-axis wind turbines (VAWTs) have recently been proposed as a possible solution for adoption in the built environment as their performance degrades less in complex and highly-turbulent flows. Some recent analyses have even shown an increase of the power coefficient for the large turbulence intensities and length scales typical of such environments. Starting from these insights, this study presents a combined numerical and experimental analysis aimed at assessing the physical phenomena that take place during the operation of a Darrieus VAWT in turbulent flows. Wind tunnel experiments provided a quantification of the performance variation of a two-blade VAWT rotor for different levels of turbulence intensity and length scale. Furthermore, detailed experiments on an individual airfoil provided an estimation of the aerodynamics at high turbulence levels and low Reynolds numbers. Computational fluid dynamics (CFD) simulations were used to extend the experimental results and to quantify the variation in the energy content of turbulent wind. Finally, the numerical and experimental inputs were synthetized into an engineering simulation tool, which can nicely predict the performance of a VAWT rotor under turbulent conditions.
Insight to Impact: The Effect of Protean Career Attitude on Employability Perceptions of IT Professionals

In the contemporary career-scape, protean career attitude is considered as an innovative approach of employees to channel their aspirations independently and to explore their future career prospects on their own. The accelerating rate of change in the nature and types of work necessitates the development of a protean attitude, which in turn will have an impact on the employability perceptions of employees. This study postulates that protean career attitude positively influences internal and external dimensions of employability, and this influence is mediated by career insight, i.e., greater goal clarity and deeper understanding of one's skills and interest. The proposed hypotheses were tested among software engineers employed in the Information Technology (IT) industry and the results indicated that protean attitude predicted both internal employability and external employability, and career insight partially mediates the associations. The study further discusses the importance of employee-centric work culture to retain protean talents.
