The waxing and waning of functional skills mathematics

ABSTRACT There have been repeated attempts to establish mathematics qualifications for lower attaining students aged 16 years and over on vocational pathways in England. In 2004, the Tomlinson Report proposed Functional Mathematics and this paper examines the trajectory of this qualification (later Functional Skills mathematics) through analysis of policy literatures over the last twenty years and empirical data from two studies in Further Education colleges. For a time, Functional Skills mathematics flourished and was becoming valued by many stakeholders but the privileging of GCSE Mathematics in recent policy has affected its status and uptake. It is important to understand this waxing and waning trajectory if future skills policy is to have better chances of long-term success. Key challenges include the unsuccessful integration of Functional Skills with the established mathematics curriculum, the difficulty of achieving qualification recognition across the vocational-academic divide and the negative unintended consequences of linked policy decisions. Raising the adult skills base is currently a policy priority in England and understanding these challenges to a skills-based qualification that is more aligned to the needs of vocational education than to schools is important.
REVITALIZING THE TEACHING OF ENGLISH AS A FOREIGN LANGUAGE THROUGH THE USE OF AUDIOVISUAL MATERIALS

work is to try to shed light on the of the practice of audiovisual in the teaching of English as a foreign language (EFL). Although it is a practice almost known of everyone nowadays, the issue of its effectiveness in the learning of a foreign language continues to be subject to several controversies due to its difficulty to be assessed. However, based on the outcomes of the present exploratory study, it remains one of the ultimate teaching methods that can allow any learner of a foreign language to easily practice his target language. To carry out this research work, a methodological approach, based on the one hand on literature searchand the other hand on interviews, focus groups as well as classroom observations, was adopted.
IMPACT OF AWARENESS AND KNOWLEDGE ON THE FINANCIAL BOOTSTRAPPING STRATEGIES UTILIZED BY IMMIGRANT ENTREPRENEURS IN SOUTH AFRICA

Purpose of the study: This paper investigated the extent to which the awareness and knowledge of financial bootstrapping determined the techniques used by immigrant entrepreneurs in the retail clothing sector in the Cape Town metropolitan area. Methodology: A quantitative research approach was used to collect and analyze data. Through self-administered questionnaires, 135 respondents participated in the study. The data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 24. Main Findings: The results point to the fact that while the respondents made use of a wide range of financial bootstrapping techniques, there was no sufficient evidence to support the fact that this was influenced by their level of awareness and knowledge of these methods. Even the respondents with limited or no knowledge of the concept of financial bootstrapping applied the strategies in their businesses. Applications of this study: This paper may directly benefit immigrant entrepreneurs, besides informing future research and policy. Novelty/Originality of this study: This paper validates the extent to which awareness and knowledge of financial bootstrapping influences the strategies utilized by immigrant entrepreneurs in South Africa.

Employee overqualification and manager job insecurity: Implications for employee career outcomes

Correspondence Berrin Erdogan, Portland State University, School of Business, Portland, OR. Email: berrine@pdx.edu Abstract In this study, we propose that manager job insecurity will moderate the nature of the relationship between perceived overqualification and employee career-related outcomes (career satisfaction, promotability ratings, and voluntary turnover). We tested our hypotheses using a sample of 124 employees and 54 managers working in a large holding company in Ankara, Turkey, collected across five time periods. The results suggested that average perceived overqualification was more strongly, and negatively, related to career satisfaction of employees when managers reported higher job insecurity. Furthermore, employee perceived overqualification was positively related to voluntary turnover when manager job insecurity was high. No direct or moderated effects were found for promotability ratings. Implications for overqualification and job insecurity literatures were discussed.
Complex type seed variety identification and recognition using optimized image processing techniques

Image processing has been functional to the numerous expansions of agricultural engineering in regulate to accomplish a quick accurate process. The procedure of physical categorization is leisurely and attains a level of bias, which is hard to be enumerated for typical type seed varieties. Seed examination and categorization can afford extra acquaintance in their creation, seeds superiority control and adulteration identification. Several techniques are utilized to resolve the struggle in perceiving and recognizing the standard type seed varieties, but the most objective is to categorize and recognize the Multifaceted Type Seed Varieties may be a quite difficult process, owing to its textural, shape and color patterns. These techniques do not provide an optimized and a correct depiction of the complex type seed varieties. The main objective of this work is to identify the complex type seed varieties for prospect fertilization within the field of agriculture. This context plans novel image processing systems to recognize, which incorporates an enhanced feature selection, and classification methodologies, which might optimize the exactness and reduce the time consumption of identifying the multifaceted type seed varieties. This novel technique provides efficient identification by feature selection and classification of those composite type seeds. The identification process, Adaptive Median Filter is employed for image enhancement; the edge detection for the image employs Sobel operator and Watershed Segmentation is used for the segmentation. Then Ant Colony Optimization (ACO) strategy is employed for the feature selection and Support Vector Machine (SVM) is employed in the classification process. The ACO based feature selection (ACOFS) provides ranges 8s to 20s of feature selection time for the dataset and the SVM classification provide 93.487% of accuracy while prediction.
Community Perception on Public Primary Schools: Implications for Sustainable Fee Free Basic Education in Rorya District, Tanzania

Despite the involvement of community participation in various development projects over the years in Tanzania, little is known of its implications on sustainability of fee free basic education in rural public primary schools. A mixed method exploratory approach, informed by ecological systems theory, employed questionnaires, FGD and interview schedules to selected parents and School Management Committee members of public primary schools in Rorya District, Tanzania. The study focused on the value of public primary school education, advantages of Fee Free primary education, perceptions of parents and School Management Committee members on community participation and relationship between parent’s perception on the value of public primary education and participation in project-based support to education. The respondents exhibited heterogeneous negative perceptions with a positive correlation between parent’s perception on the value of public primary education and participation in project-based support to education (r =.510, p=000<0.01). The larger majority 64.3% of parent respondents with grade 7 education was deemed a factor that influenced negative perception. The researcher recommends that the Government authorities need to impart community economic productivity skills; the District Authorities further need to conduct community awareness on the importance of participation. Finally, the Ministry of Education in collaboration with the other stakeholders should mobilize funds and sensitize communities on the value of primary education and the importance of their participation in community development programs to support education.

Turning a blind eye: employees’ perception of management control systems and misconduct

This study examines the impact of employees’ perceptions of management control systems (MCS) as a threat in two forms of misconduct: deliberate ignorance and workplace deviance. Drawing on the theory of cognitive dissonance, we predict that a perceived threat is associated with a decrease in workplace deviance but may also trigger unintended consequences, such as deliberate ignorance. Hypotheses were tested using survey data from three large hospitals. The results from partial least square regressions suggest that employees’ perceptions of MCS as a threat demonstrate (1) a negative curvilinear effect on workplace deviance and (2) a positive linear association with deliberate ignorance. Additionally, we found that the need for professional autonomy moderated the effect of employees’ perception of MCS as a threat in terms of both forms of misconduct. Therefore, aims to extend the growing body of research on the consequences of control systems in employees’ behavior. Specifically, we provide new empirical evidence on how employees perceive MCS and the (un)intended consequences of control.

The finding revealed that with mediation, career development, justice organization, and quality of work-life affected the OCB and organizational commitment. It showed that increase organizational commitment and OCB can be taken to improve career development, organizational justice, and the quality of work-life.
Diversification of retinoblastoma protein function associated with cis and trans adaptations

Retinoblastoma proteins are eukaryotic transcriptional co-repressors that play central roles in cell cycle control, among other functions. Although most metazoan genomes encode a single retinoblastoma protein, gene duplications have occurred at least twice: in the vertebrate lineage, leading to three genes encoding Rb, p107, and p130, while separately in the Drosophila lineage an ancestral Rbf1 gene and a derived Rbf2 gene. Structurally, Rbf1 resembles p107 and p130 most closely, and mutation of the gene is lethal, while Rbf2 is more divergent, and is not essential for development. Rbf1 has been demonstrated to be a potent repressor of canonical cell-cycle promoters, unlike Rbf2. The retention of Rbf2 over 60 million years in the entire Drosophila lineage points to essential functions, however. We show here that Rbf2 regulates a broad set of cell growth control related genes, and can antagonize Rbf1 on specific sets of promoters. Rbf2 null mutants exhibit abnormal development of the female reproductive tract, with reduced egg laying, while heterozygous null mutants exhibit an increased rate of egg deposition, suggesting that the normal function of this protein is critical for optimal control of fertility. The structural alterations found in conserved regions of the Rbf2 gene suggest that this gene was sub- or neofunctionalized to develop specific regulatory specificity and activity. We define cis regulatory features of Rbf2 target genes that allow preferential repression by this protein, indicating that it is not merely a weaker version of the ancestral protein. The specialization of retinoblastoma function in Drosophila may reflect a parallel evolution found in vertebrates, and raises the possibility that cell growth control is equally important to cell cycle function for this conserved family of transcriptional corepressors.
Crane Hook Detection Based on Mask R-CNN in Steel-making Plant

This paper proposes a solution based on machine vision and deep learning for the hidden safety problems that the hook does not match the ladle trunnion correctly, which is one of the hidden dangers during the crane lifting the ladle. Mask Region Convolutional Neural Network (Mask-RCNN) was introduced to segment the crane hook and find the bottom point of the hook contour. The trunnion center point can be directly located in image by painting a special color on it. Then determine whether the hook and trunnion match correctly by calculating the angle between the horizontal line and the line connecting the bottom point of the hook and the trunnion center point. According to the experimental rsulrs of 100 test images, that the average accuracy (AP) of our methods for hook segmentation can reach 92%. And the accuary of the safety judgment algorithm has reached 96%.
Enhancer transcription identifies cis-regulatory elements for photoreceptor cell types

ABSTRACT Identification of cell type-specific cis-regulatory elements (CREs) is crucial for understanding development and disease, although identification of functional regulatory elements remains challenging. We hypothesized that context-specific CREs could be identified by context-specific non-coding RNA (ncRNA) profiling, based on the observation that active CREs produce ncRNAs. We applied ncRNA profiling to identify rod and cone photoreceptor CREs from wild-type and mutant mouse retinas, defined by presence or absence, respectively, of the rod-specific transcription factor (TF) Nrl. Nrl-dependent ncRNA expression strongly correlated with epigenetic profiles of rod and cone photoreceptors, identified thousands of candidate rod- and cone-specific CREs, and identified motifs for rod- and cone-specific TFs. Colocalization of NRL and the retinal TF CRX correlated with rod-specific ncRNA expression, whereas CRX alone favored cone-specific ncRNA expression, providing quantitative evidence that heterotypic TF interactions distinguish cell type-specific CRE activity. We validated the activity of novel Nrl-dependent ncRNA-defined CREs in developing cones. This work supports differential ncRNA profiling as a platform for the identification of cell type-specific CREs and the discovery of molecular mechanisms underlying TF-dependent CRE activity. Highlighted Article: Non-coding RNA profiling identifies cell type-specific enhancer elements in the developing mouse retina.
Effect of Aluminium oxide on inhibition activity of a deep-sea Penicillium sp. against Aspergillus parasiticus

In this study, the effects of aluminium oxide content, micro particle diameter and rotational speed on the activity of fermentation broth of deep-sea Penicillium MHE1 in inhibiting the growth of Aspergillus parasiticus NFRI-95 hypha and aflatoxin production were studied by uniform design. The optimal combination is obtained by regression analysis and experimental verification. The optimal combination is 1.015 g/L and 101.5 mesh in diameter for aluminium oxide, and 108.6 r/min for rotation incubation. Under these conditions, the mycelium inhibition rate of fermentation broth of strain MHE1 to Aspergillus parasiti NFRI-95 reached 85.88%, and the aflatoxin inhibition rate reached 100%, which increased by 7.1% and 9.2% respectively compared with that before optimization.
Moral Foundations theory in the context of a political scandal

Aim: The aim of this study was to examine the moral foundations structure in the Croatian population, and to examine possible changes in moral foundation structure after a major political scandal in Croatia. Methods: We conducted an online survey using Moral Foundations Questionnaire and Key Social Issues Scale, which was distributed in two waves, in 2009 and 2014. Participants were invided from the Faculties of Humanities and Social Sciences at the universities in Zagreb and Split and asked to distribute the survey to colleagues and friends. Results: 3000 participants completed the survey in 2009, 1323 participants completed the survey in 2014. In both samples, most participants reported that they relied more on individual foundations of “Care/Harm” and “Fairness/Cheating”, than on relational foundations of “Loyalty/Betrayal”, “Authority/Subversion” or “Sanctity/Degradation”, which are typically more valued by traditionally oriented or conservative individuals. Comparison of the two measurement time points indicated that scores on traditional foundations significantly decreased, while liberal values increased. These changes were triangulated and confirmed by the results on the Key Social Issues Scale. Conclusion: This is, to the best of our knowledge, the first study which analysed the changes in the moral foundations structure after a major political scandal, implicating that negative political events may decrease the expression of moral foundations related to the values which are nurtured by a political party involved in the scandal.
Visualizing ATP-dependent substrate-processing dynamics of the human 26S proteasome at near-atomic resolution

The proteasome is an ATP-dependent 2.5-megadalton machine responsible for ubiquitylated protein degradation in all eukaryotic cells. Here we present cryo-EM structures of the substrate-engaged human 26S proteasome in seven conformational states at 2.8-3.6 Å resolution, captured during polyubiquitylated protein degradation. These structures visualize a continuum of dynamic substrate-proteasome interactions from ubiquitin recognition to processive substrate translocation, during which ATP hydrolysis sequentially navigate through all six ATPase subunits. Three principle modes of coordinated ATP hydrolysis are observed, featuring hydrolytic events in two oppositely positioned ATPases, in two consecutive ATPases, and in one ATPase at a time. They regulate deubiquitylation, translocation initiation and processive unfolding of substrates, respectively. A collective power stroke in the ATPase motor is generated by synchronized ATP binding and ADP release in the substrate-engaging and disengaging ATPases, respectively. It is amplified largely in the substrate-disengaging ATPase, and propagated unidirectionally by coordinated ATP hydrolysis in the third consecutive ATPase.
Cross-national analysis of global security discourse using word embeddings

This study conducts a systematic investigation of discursive dynamics in the context of policy deliberations on international peace and security, by performing cutting-edge text analysis on the entire body of meeting records of the Security Council of the United Nations for the past quarter of a century (1994-2019). Focusing on one of the most consequential notions for the council’s policy-making, "threat to the peace," it employs an unsupervised machine learning model, broadly termed "word embedding," to analyze how this notion has been discussed by relevant members of the council, especially its five permanent members, during the period under investigation. The study reveals persistent patterns of cross-national convergence and divergence in security discourse, including, most notably, a considerable degree of correlation in how to conceive international threats found between the close-knit Western allies in the council and their Russian counterpart.
Demonstration of Package Level 3D-printed Direct Jet Impingement Cooling applied to High power, Large Die Applications

This work presents, for the first time, a package- level, bare die liquid jet impingement 3D polymer microfluidics heatsink fabricated using 3D printing, or additive manufacturing for large die size and high-power applications. The heatsink achieves a chip temperature increase of 17.5°C at a chip power of 285 W for a coolant flow rate of 3.25 LPM, demonstrating that 3D printing enables the design for low-cost, high efficiency direct on-chip microfluidic heatsink with complex internal 3D manifold liquid delivery channels. The measurement results show that the jet impingement cooling performance can be successfully described using a unit cell approach, allowing an easy scaling of the thermal performance for arbitrary die size applications. Long term thermal tests of 1000h show a constant thermal performance and no degradation of the cooler material.
A Quantitative Investment Model Based on Random Forest and Sentiment Analysis

In recent years, under the influence of economic globalization and anti-globalization, the stock market has experienced great fluctuations in China. Quantitative investment has attracted a lot of attention because of its characteristics of maintaining stable returns. Existing research is unilaterally based on quantitative data or qualitative data for analysis to construct a quantitative investment model. This paper considers both quantitative and qualitative data to construct a more comprehensive model than that in the past. Based on the optimized database, we present a combinational model named RF-SA, which is composed of random forest and sentiment analysis model. First of all, this paper uses the SBS algorithm to select the characteristics of stock transaction historical data, optimizes the prediction database, reduces data redundancy, and improves the accuracy of the model. Secondly, we analyze the characteristics of the Chinese stock market and study the advantages and disadvantages of many data mining algorithms, and select random forest model, the most suitable model, to build the first step of stock selection model. Then, through the analysis of public opinion, the confidence index of the stockholders is calculated; on this basis, the results of the RF model and the confidence index are combined to make a second choice for the stock, and the quantitative investment portfolio is obtained, and excess returns can be obtained. The results of empirical data show that, the RF-SA model obtains a higher rate of return than the investment model of the Shanghai Stock Index.
