description: Kajian ini dijalankan bagi mengenal pasti tahap kemahiran dan sikap guru terhadap penggunaan multimedia dalam pengajaran dan pembelajaran al-Quran untuk murid Autisme. Kajian ini dilakukan menggunakan set soal selidik yang telah dilengkapkan oleh 40 orang guru yang mengajar di kelas Program Pendidikan Khas Integrasi (PPKI) yang dipilih secara rawak. Data kuantitatif daripada soal selidik ini dianalisis secara deskriptif menggunakan SPSS versi 22 bagi mendapatkan kekerapan (frekuensi), peratusan, min dan sisihan piawai. Analisis korelasi Pearson digunakan untuk menentukan hubungan antara tahap kemahiran dengan sikap guru menggunakan multimedia dalam pengajaran dan pembelajaran al-Quran murid Autisme. Hasil analisis kajian mendapati, tahap kemahiran guru (M=3.63, SP.=0.82) dan sikap guru (M=3.80, SP.=0.71) berada pada aras sederhana tinggi. Sementara itu, kajian ini juga menunjukkan wujud hubungan yang signifikan antara tahap kemahiran dengan sikap guru. Sememangnya tahap kemahiran dan sikap guru ke arah menggunakan multimedia dalam pengajaran adalah positif tetapi mempunyai kelemahan dari aspek pengaplikasian item-item multimedia. Justeru, semasa menjalankan proses pengajaran, seseorang guru mesti mengambil kira mengenai tahap kemahiran untuk diaplikasikan dan kebersediaan sikap guru untuk membina proses pengajaran berasaskan multimedia agar menjadi lebih efektif

(This study was conducted to identify the teacher skill level and attitude towards the use of multimedia in the teaching and learning of the Holy Koran for Autism students. This study was conducted using a set of questionnaires that were completed by 40 teachers who teach in the Integrated Special Education Program (PPKI) class selected by random. These quantitative data from the questionnaire were analyzed descriptively through SPSS software, version 22 to obtain the frequency, percentage, mean and standard deviation. Pearson correlation analysis was used to determine the relationship between skill level and teacher attitude towards using multimedia in the teaching and learning of the Holy Koran for Autism students. The results of the analysis of the study found that the teacher skill level (M=3.63, SD.=0.82) and teacher attitude (M=3.80, SD.=0.71) were at a moderate and high level. Meanwhile, this study also shows that there is a significant relationship between skill level and teacher attitude. Indeed, the teacher skill level and attitude towards using multimedia in teaching is positive but has weaknesses in terms of the application of multimedia items. Thus, while conducting the teaching process, a teacher must take into account the skill level to be applied and the readiness of the teacher attitude to build a multimedia-based teaching process to be more effective)

description: Precipitation of exceptionally 13C-depleted authigenic carbonate is a result of, and thus a tracer for, sulphate-dependent anaerobic methane oxidation, particularly in marine sediments. Although these carbonates typically are less depleted in 13C than in the source methane, because of incorporation of C also from other sources, they are far more depleted in 13C (δ13C as light as -69‰ V-PDB) than in carbonates formed where no methane is involved. Here we show that oxidation of biogenic methane in carbon-poor deep groundwater in fractured granitoid rocks has resulted in fracture-wall precipitation of the most extremely 13C-depleted carbonates ever reported, δ13C down to -125‰ V-PDB. A microbial consortium of sulphate reducers and methane oxidizers has been involved, as revealed by biomarker signatures in the carbonates and S-isotope compositions of co-genetic sulphide. Methane formed at shallow depths has been oxidized at several hundred metres depth at the transition to a deep-seated sulphate-rich saline water. This process is so far an unrecognized terrestrial sink of methane.

description: Background Lower Saxony (Germany) has the highest installed electric capacity from biogas in Germany. Most of this electricity is generated with maize. Reasons for this are the high yields and the economic incentive. In parts of Lower Saxony, an expansion of maize cultivation has led to ecological problems and a negative image of bioenergy as such. Winter triticale and cup plant have both shown their suitability as alternative energy crops for biogas production and could help to reduce maize cultivation. Results The model Biomass Simulation Tool for Agricultural Resources (BioSTAR) has been validated with observed yield data from the region of Hannover for the cultures maize and winter wheat. Predicted yields for the cultures show satisfactory error values of 9.36% (maize) and 11.5% (winter wheat). Correlations with observed data are significant (P

description: We report on a 30ksec XMM-Newton observation of the central region of the Cha I star forming cloud. Virtually all known T Tauri star members and most of the very-low mass objects including two bona-fide brown dwarfs (spectral types M7.5 and M8) are detected. We identify several new candidate members in the X-ray image. Spectral analysis of the X-ray bright stars shows that previous X-ray studies in Cha I have underestimated the X-ray luminosities, as a result of simplified assumptions on the spectral shape. No dramatic changes in the correlations of X-ray luminosity with age, effective temperature and mass are seen at the substellar boundary, and the lowest-mass objects behave similar to the higher-mass T Tauri stars in terms of variability. Thus the same dynamo mechanism seems to operate in both low-mass stars and brown dwarfs, at least at young ages. On the other hand, the only two A-type stars in the field show very different X-ray properties, suggesting that various emission mechanisms may be at work in intermediate-mass stars.

description: Drawing inspiration from American institutionalism and new institutional economics, this paper discusses the rise of large corporate farms as the transition from the classic capitalist firm to the corporate form of organization based on the separation of ownership and control. Three case studies from the Brazilian cerrado show the rise of large corporate farms to be enabled and impelled by the advance of agricultural production technologies and the search for scale economies. The key finding from the case studies is that complex technology not only necessitates large-scale farming but also generates technical and organizational solutions to the potentially pervasive agency problems. In addition to the use of sound corporate governance practices, these solutions include organizational architecture encompassing computer-aided accounting and budgeting systems, incentive-based compensation, clear definition of performance goals, and delegation of operational decisions to farm managers. Furthermore, organizational architecture has been shown to promote a culture of trust and accountability, which counteract the opportunistic tendencies of farm managers and workers

description: We construct a nonconforming virtual element method (ncVEM) based on approximation spaces that are enriched with special singular functions. This enriched ncVEM is tailored for the approximation of solutions to elliptic problems, which have singularities due to the geometry of the domain. Differently from the traditional extended Galerkin method approach, based on the enrichment of local spaces with singular functions, no partition of unity is employed. Rather, the design of the method hinges upon the special structure of the nonconforming virtual element spaces. We discuss the theoretical analysis of the method and support it with several numerical experiments. We also present an orthonormalization procedure drastically trimming the ill-conditioning of the final system.

description: We continue our study of heterotic compactifications on non-Kahler complex manifolds with torsion. We give further evidence of the consistency of the six-dimensional manifold presented earlier and discuss the anomaly cancellation and possible supergravity description for a generic non-Kahler complex manifold using the newly proposed superpotential. The manifolds studied in our earlier papers had zero Euler characteristics. We construct new examples of non-Kahler complex manifolds with torsion in lower dimensions, that have non-zero Euler characteristics. Some of these examples are constructed from consistent backgrounds in F-theory and therefore are solutions to the string equations of motion. We discuss consistency conditions for compactifications of the heterotic string on smooth non-Kahler manifolds and illustrate how some results well known for Calabi-Yau compactifications, including counting the number of generations, apply to the non-Kahler case. We briefly address various issues regarding possible phenomenological applications.

description: Agroholdings are ‘horizontally and vertically integrated agricultural and agribusiness enterprises, which often have an explicit holding structure consisting on quite a number of legal entities’. This might be true in the countries the authors evaluated, but it certainly is not the case in Argentina, where horizontal and vertical coordination (rather than integration) is the norm. During the last 25 years the institutional environment impacted the way farming is organized in Argentina, mainly by using contracts between different players and service providers. The agricultural production sector increasingly shifted from a low to medium and to a large-scale business model, and production units expanded horizontally by means of land leases (coordination) and purchases (integration) in order to increase the scale of production and dilute fixed costs in an attempt to generate higher margins. In that sense this paper arises four questions: (1) why is it that in Argentina large-scale farming is predominantly done via contracts instead of vertical and horizontal integration?; (2) why have large-scale farming networks recently stalled or even declined in terms of area growth?; (3) how and why do these networks vary their scale of production, locations and strategies?; and (4) what can we expect in terms of evolution of different types of large-scale farming? It is observed that in Argentina there were different institutional contexts, sometimes with clearer and more stable conditions and low levels of uncertainty, sometimes with higher intervention policies and transaction costs. The paper discusses how new organizations emerged during different periods and scenarios, in a context of increased international demand for agricultural commodities. The most relevant conclusions drawn from this analysis are that, in Argentina’s agriculture, there is a continuous shift from ownership to management, although consolidation towards larger scale entities has slowed down due to the existence of institutional and policy restrictions.

description: This article explores the current practice of motivating agricultural workers in post-socialist settings. In addition, it attempts to evaluate the different wage systems observed in reality and better understand under which conditions they are reformed. It does so by contrasting the experience of two extreme cases representing fast and slow reform advance, East Germany and North Kazakhstan. The primary data for the analysis comes from cross-sectional farm surveys conducted by various researchers in both countries. East German farmers quickly replaced the inherited Soviet-style piece rate payment system by simple time rate schemes, augmented by wage premia for certain performance parameters, especially in livestock. To the contrary, the piece rate approach persists in many farms in North Kazakhstan. Moreover, the latter rarely use non-wage incentives to motivate their workers. In Kazakhstan, farms using either mixed systems or pure piece rates were more productive than the reference group using pure time rates. Labour cost per worker were lowest for pure time rate systems in both countries, followed by mixed bonus systems, whereas pure piece rate systems implied the highest cost in Kazakhstan. Kazakhstani managers tend to move away from the Soviet piece rate system if external investors become engaged in farming operations.

description: Excerpts from the report: Within recent years there have been important changes in merchandising practices in retail grocery stores. In many stores today the consumer has the opportunity to select the type or quantity of products desired without being influenced by a clerk. Thus, the consumer's decision is more directly affected by the display, type and size of package, price in relation to competing products, labeling, advertising, and many other retailing factors than formerly. Increased production of agricultural products through technical advances also has brought pressure upon the marketing system to move larger quantities into the hands of consumers. Therefore, it is important that the merchandising program, an important facet of the marketing system, function at a high level of effectiveness. Experimental research was carried out in a selected group of retail food stores in Pittsburgh, Pa., during the spring and winter of 1954-55, directed toward determining which of several methods of merchandising would be most successful in moving larger quantities of each of three products into consumption.

Special interest was focused on the morphology of choanocyte-chambers and choanocytes, embryonal stages, larvae, spicules, and the contact between the substrate i}nd the sponge. All choanocytes of the examined lubomirskiid species showed similar mOrphologicai patterns. The flagellum is located in a little pit and the kinetosome anchored with microtubules. In September Baikalospongia contained allready fully developed Parenchymellae, while Swartschewskia exhibited cleavage stages and Lubomirskia large oocytes only. Between sponge and substrate a biofilm-layer was detected.
The 5d Superconformal Index at Large $N$ and Black Holes

description: We study the large $N$ limit of the superconformal index of a large class of 5d $\mathcal{N}=1$ superconformal field theories and show it is given by the square of the partition function on the squashed five-sphere. We show this simple relation implies a Cardy formula in 5d, which is valid in an "extended" regime in which fugacities are finite and $N$ is large. For theories with weakly coupled gravity duals we conjecture this large $N$ Cardy formula universally accounts for the microscopic entropy of spinning black holes in AdS$_{6}$. We check this explicitly for known black hole solutions in massive type IIA and type IIB string theory, carrying two angular momenta and one electric charge, and predict the entropy of black holes carrying multiple electric charges, yet to be constructed. We also discuss large $N$ properties of the $S^{3}_{b}\timesΣ_{\mathfrak{g}}$ partition function, extending previous results to theories with type IIB duals.

description: The paper argues that transparency of large corporate farms operating in transition economies is the factor that affects their competitive position as it helps to preserve access to international equity markets and to reduce uncertainty that arises from imperfect local input markets. We demonstrate that the corporate transparency of large farms is an issue of both public interest and private investor interest and decompose the construct of transparency respectively. Because firms tend to exhibit heterogeneous transparency strategies when facing common sets of pressures, we draw upon four case studies of different Ukrainian agroholdings using the suggested decomposition of the transparency construct. We find that large farms may benefit substantially in the long run if they establish effective corporate governance mechanisms and provide more evidence that they contribute positively to corporate social responsibility and rural development.

description: We present results on the study of the stellar population in Early-Type galaxies (ETGs) belonging to 151 Compact Groups (CGs). We also selected a field sample composed of 846 ETGs to investigate environmental effects on galaxy evolution. We find that the dependences of mean stellar ages, [Z/H] and [$α$/Fe] on central stellar velocity dispersion are similar, regardless where the ETG resides, CGs or field. When compared to the sample of centrals and satellites from the literature, we find that ETGs in GCs behave similarly to centrals, especially those embedded in low-mass haloes ($M_{h} < 10^ {12.5}M_{\odot}$). Except for the low-mass limit, where field galaxies present a Starforming signature, not seen in CGs, the ionization agent of the gas in CG and field galaxies seem to be similar and due to hot, evolved low-mass stars. However, field ETGs present an excess of H$α$ emission relative to ETGs in CGs. Additionally, we performed a dynamical analysis, which shows that CGs present a bimodality in the group velocity dispersion distribution - a high and low-$σ$ mode. Our results indicate that high-$σ$ groups have a smaller fraction of spirals, shorter crossing times, and a more luminous population of galaxies than the low $σ$ groups. It is important to emphasize that our findings point to a small environmental impact on galaxies located in CGs. The only evidence we find is the change in gas content, suggesting environmentally-driven gas loss.

description: We propose a new method to calculate Faraday rotation measure maps from multi-frequency polarisation angle data. In order to solve the so called n-pi ambiguity problem which arises from the observationally ambiguity of the polarisation angle which is only determined up to additions of +-n*pi, where n is an integer, we suggest using a global scheme. Instead of solving the n-pi ambiguity for each data point independently, our algorithm, which we chose to call "Pacman" (Polarisation Angle Correcting rotation Measure ANalysis), solves the n-pi ambiguity for a high signal-to-noise region ``democratically'' and uses this information to assist computations in adjacent low signal-to-noise areas.

A high resolution comparative study of the slowly contracting, starless cores, L694-2 and L1544

description: We present interferometric observations of N2H+(1-0) in the starless, dense core L694-2 and compare them to previously published maps of L1544. Both cores are starless, centrally condensed, and show spectral signatures of rotation and collapse. We fit radially averaged spectra using a two-layer infall model and measure the variation of opacity and infall speed in each core. Both functions increase toward the center of each core but the radial gradients are shallower, and the central values lower, in L694-2. This general behavior is predicted in models of gravitational collapse with thermal plus magnetic support and the lower values in L694-2 may be due to its lower mass or a slightly earlier evolutionary state. In either case, it appears that both cores will form stars within a few 10^4 years.

description: This study examines the sales performance of agribusinesses based in the humid tropics of Latin America. Its focus is on strategic positioning and specific functional areas, ranging from marketing to human resources and purchasing. This paper contributes to the literature through a novel methodological approach, a configurational angle, which allows for the identification of multiple causal explanations for consistently good sales performance. It also advances the research agenda on Latin American businesses by studying the strategic recipes of agribusinesses. The findings have both theoretical and managerial implications.

description: We investigate the transverse momentum dependence of pion HBT radii on the basis of a hydrodynamical model. Recent experimental data show that $R_{\text{out}}/R_{\text{side}} < 1$, which suggests a strong opaqueness of the source. In addition to the opaqueness naturally caused by transverse flow, we introduce an extrinsic opacity by imposing restrictions on the pion emission angle. Comparing the HBT radii obtained from the normal Cooper-Frye prescription and the opaque emission prescription, we find that $R_{\text{out}}/R_{\text{side}}$ is less than unity only for small values of the transverse momentum with an opaque source. However, HBT radii for large values of the transverse momentum are dominated by the transverse flow effect and are affected less by the source opaqueness.

description: The purpose of this study is to examine the relation of external relationships and entrepreneurial infrastructure on the entrepreneurial orientation (EO) of tea manufacturing firms. An empirical survey was conducted with tea manufacturing firms located in a low grown area in Sri Lanka. Primary data were collected by administering a structured questionnaire at 109 tea factories. The findings indicated the importance of external relationships; specifically, relationships with supply chain partners and relationships with government facilitating institutions enhance the EO of tea manufacturing firms. However, relationships with other tea factories and educational and research institutions are not significant influences on firms’ EO in the context of the Sri Lankan tea industry. When considering the dimensions of EO, risk taking is influenced by external relationships and not innovativeness and proactiveness. Further, the entrepreneurial infrastructure provided by related institutions except other tea factories have positive links with EO. Such contributions are important to managers and policy makers to enhance the EO of tea manufacturing firms when facing competitiveness in the global market.

description: This paper analyses governance structures in Uganda’s smallholder pig value chains by applying the New Institutional Economics framework. It utilises cross sectional and qualitative survey data from randomly selected pig value chain actors in 4 districts. A multinomial logit model is applied to assess the determinants of vertical integration among pig traders. The findings indicate that most relationships at the pig production node of the value chain are based on spot market governance structures supported by personal relationships and trust. Live pig traders are mostly vertically integrated. High integration levels of the pig traders are positively influenced by access to market information, value of investments in the value chain, and dedicated asset specificity in terms of backyard slaughter premises. Upgrading opportunities in the value chain in the form of value addition strategies, policy implementation and promotion of business models that link producer organisations to quality inputs and service suppliers through contractual arrangements are identified.
title: MOOC Educators: Who They Are And How They Learn
Creators: name: Papathoma, Tina
Publisher: name: The Open University
Year: 2019

description: This study set out to answer the following research questions: who teaches in Massive Open Online Courses (MOOCs) and how do these different educators learn to teach? To do this, it utilised Tynjälä’s theoretical model of Integrative Pedagogy that brings together different elements of professional expertise. To this end, a ‘multiple case study’ was conducted, with a focus on teaching activities and who is involved in them, as well as on educators’ ‘processes of knowledge building’, and the forms of knowledge they integrate. The data comprised 28 interviews with professionals with teaching responsibilities in seven MOOCs on the subject of History and of Politics on the FutureLearn platform. The seven cases were analysed using different strategies (theoretical propositions, ground-up data, and rival explanations). The analysis showed that the role of ‘educator’ is filled not only by those with the titles used by the FutureLearn platform, but also by other professionals who take pedagogical decisions. MOOC teaching activities are diverse, different from face-to-face teaching and it is difficult for them to be carried out by a single individual. Educators in different courses and different universities used diverse models of work practice, each of which had advantages and disadvantages. MOOC educators learned to teach effectively when they had a shared goal, worked in transparent ways and involved interdisciplinary teams in a timely manner. These findings can help institutions and platforms to design better Continuing Professional Development programmes and, ultimately, more effective MOOC learning journeys. Drawing on this evidence, the original contribution to knowledge of this thesis is a new conceptualisation of who the educators of MOOCs are, developed by uncovering the roles of professionals who carry out teaching on these courses, the wide variety of teaching activities involved and the ways people learn to work towards these.

description: Corporate Social Responsibility (CSR) has long been an issue worldwide, and more and more industries are taking note. One important example is the poultry industry in Germany, which has become a focal point of public debate. Increasingly, consumers are demanding that firms take responsibility for their corporate actions. The goals of this study were, first, to analyze consumers’ preferences for poultry firms’ CSR commitment with the help of an adaptive conjoint analysis. Second, a cluster analysis is set out to define consumer groups according to their preferences. With regard to CSR, consumers in this study were most concerned with product quality, animal welfare and employee issues. TV, newspaper and product packaging are their most preferred information sources. Three clusters were identified. Firms should focus more on communicating what their firm’s commitment comprises and should adapt their CSR activities and firm communication methods to the preferences of different target groups.

Repeatedly Evolved Host-Specific Ectosymbioses between Sulfur-Oxidizing Bacteria and Amphipods Living in a Cave Ecosystem

description: Ectosymbioses between invertebrates and sulfur-oxidizing bacteria are widespread in sulfidic marine environments and have evolved independently in several invertebrate phyla. The first example from a freshwater habitat, involving Niphargus ictus amphipods and filamentous Thiothrix ectosymbionts, was recently reported from the sulfide-rich Frasassi caves in Italy. Subsequently, two new Niphargus species, N. frasassianus and N. montanarius, were discovered within Frasassi and found to co-occur with N. ictus. Using a variety of microscopic and molecular techniques, we found that all three Frasassi-dwelling Niphargus species harbor Thiothrix ectosymbionts, which belong to three distinct phylogenetic clades (named T1, T2, and T3). T1 and T3 Thiothrix dominate the N. frasassianus ectosymbiont community, whereas T2 and T3 are prevalent on N. ictus and N. montanarius. Relative distribution patterns of the three ectosymbionts are host species-specific and consistent over different sampling locations and collection years. Free-living counterparts of T1–T3 are rare or absent in Frasassi cave microbial mats, suggesting that ectosymbiont transmission among Niphargus occurs primarily through inter- or intraspecific inoculations. Phylogenetic analyses indicate that the Niphargus-Thiothrix association has evolved independently at least two times. While ectosymbioses with T1 and T2 may have been established within Frasassi, T3 ectosymbionts seem to have been introduced to the cave system by Niphargus.

description: Agricultural employers increasingly are turning to the foreign guest worker program, known as H-2A, as a means to secure a legal workforce. This paper outlines the procedural aspects and costs of recruiting and hiring H-2A workers. Cost data is from a 2014 survey of citrus harvesters and defines pre-employment costs as filing fees, advertising, surety bonds, travel, and housing. The pre-employment costs associated with guest workers are estimated to be nearly $ 2,000 per worker. The survey was motivated by the ‘60-minute rule’ imposed by the U.S. Department of Labor prior to the 2012-13 citrus harvesting season. Cost data were collected across two crop season, 2012-13 and 2013-14, to analyze the cost implications of the rule. We found that the 60-minute rule significantly increased filing fees. These fees, however, represent a very small share of total costs and overall pre-employment costs associated with the H-2A program did not significantly change.

description: Tensor network states are expected to be good representations of a large class of interesting quantum many-body wave functions. In higher dimensions, their utility is however severely limited by the difficulty of contracting the tensor network, an operation needed to calculate quantum expectation values. Here we introduce a method for the time-evolution of three-dimensional isometric tensor networks which respects the isometric structure and therefore renders contraction simple through a special canonical form. Our method involves a tetrahedral site-splitting which allows to move the orthogonality center of an embedded tree tensor network in a simple cubic lattice to any position. Using imaginary time-evolution to find an isometric tensor network representation of the ground state of the 3D transverse field Ising model across the entire phase diagram, we perform a systematic benchmark study of this method in comparison with exact Lanczos and quantum Monte Carlo results. We show that the obtained energy matches the exact groundstate result accurately deep in the ferromagnetic and polarized phases, while the regime close to the critical point requires larger bond dimensions. This behavior is in close analogy with the two-dimensional case, which we also discuss for comparison.
