Variable stars in the VVV globular clusters

Context. The Galactic globular clusters (GGCs) located in the inner regions of the Milky Way suffer from high extinction that makes their observation challenging. High densities of field stars in their surroundings complicate their study even more. The VISTA Variables in the Via Lactea (VVV) survey provides a way to explore these GGCs in the near-infrared where extinction effects are highly diminished. Aims. We conduct a search for variable stars in several inner GGCs, taking advantage of the unique multi-epoch, wide-field, near-infrared photometry provided by the VVV survey. We are especially interested in detecting classical pulsators that will help us constrain the physical parameters of these GGCs. In this paper, the second of a series, we focus on NGC 6656 (M 22), NGC 6626 (M 28), NGC 6569, and NGC 6441; these four massive GGCs have known variable sources, but quite different metallicities. We also revisit 2MASS-GC 02 and Terzan 10, the two GGCs studied in the first paper of this series. Methods. We present an improved method and a new parameter that efficiently identify variable candidates in the GGCs. We also use the proper motions of those detected variable candidates and their positions in the sky and in the color-magnitude diagrams to assign membership to the GGCs. Results. We identify and parametrize in the near-infrared numerous variable sources in the studied GGCs, cataloging tens of previously undetected variable stars. We recover many known classical pulsators in these clusters, including the vast majority of their fundamental mode RR Lyrae. We use these pulsators to obtain distances and extinctions toward these objects. Recalibrated period–luminosity–metallicity relations for the RR Lyrae bring the distances to these GGCs to a closer agreement with those reported by Gaia, except for NGC 6441, which is an uncommon Oosterhoff III GGC. Recovered proper motions for these GGCs also agree with those reported by Gaia, except for 2MASS-GC 02, the most reddened GGC in our sample, where the VVV near-infrared measurements provide a more accurate determination of its proper motions.
Exploring Beliefs and Practices of Secondary Mathematics Teachers Who Participated in a Standards-Based Pre-Service Education Program

The National Council of Teachers of Mathematics has challenged all mathematics teachers to use the Standards documents (1989, 1991, 1995, & 2000) as guidelines for teaching mathematics. Many pre-service programs are now presenting curricula that are Standards-based. Five case studies were used to investigate the teaching beliefs and practices of mathematics teachers who had participated in a Standards-based pre-service education. One teacher held beliefs in alignment with the guidelines of the Standards and effectively implemented them in her classroom regardless of the obstacles. Another teacher strongly held Standards-based beliefs but had difficulty incorporating these beliefs into her teaching practices due to the obstacles of curriculum, high-stakes testing, and classroom management. The other three teachers held mostly traditional beliefs and incorporated traditional teaching strategies. Four of the teachers lowered their expectations of students based on the students’ demographics, such as academic level and socioeconomic status.
Beyond Business Basics at the Base-of-the-Pyramid: The Perspectives of Multinational Corporations

This paper is a collaborative effort between the academia and industry practitioners serving in the Base-of-the-Pyramid (BOP) segment in emerging markets. It focuses on understanding the key success factors and challenges that multinational corporations (MNCs) face in their BOP ventures. Different from other work on BOP markets, this paper primarily focuses on in-depth understanding of MNCs’ learning in the BOP field, and how MNCs are using the learning to further engage with the BOP consumers in order to generate greater success in their ventures. This papers aims to enhance further learning about BOP ventures both among the academia and industry practitioners. Several themes emerged from the in-depth qualitative interviews with industrial experts in the BOP segments: (1) the need for quality consumer research, (2) the capability to standardize core technology, (3) understanding BOP brand value, (4) communicating brand value to BOP consumers, (5) leveraging technological leapfrogging capabilities at the BOP markets; (6) creating access and distribution capabilities and (7) assessing and minimizing environmental impact.
Computerised data acquisition and processing in measurement of raster scales

The development and implementation of computerised control of measurements and the simulation and calculation of measurement of raster scales and transducers are discussed. The number of strokes in circular raster scales exceeds hundreds or thousands, so it is impossible to calibrate the scales and calculate the results using conventional methods without computer interaction. An example of the new approach to computer simulation of the circular scales calibration process with the reference measure is given, creating the model of measurement and simulating the instrumental steps performed on the object, the comparison with reference measure and the evaluation of systematic error, uncertainty, numerical and graphical presentation of the results.
Toward Phase-Recovery Optical Nanoscopes

We discuss how recent advances in phase-recovery imaging techniques in combination with plasmonic UTSs (ultrathin condensers) with a semiconductor substrate have paved the way for the development of novel optical nanoscopes. These optical nanoscopes are capable of imaging the intensity and the phase of the electric field distribution at the sample’s plane.
Developing a Framework for a Fine-Grained Computational Theory of Algebra Learning.

Theoretical tools from cognitive science were used to put together a framework for a fine-grained theory of how students learn elementary algebra in the classroom. Developing the framework included assessing the shortcomings of current models, evaluating whether unified theories of cognition can be adapted for learning mathematics in the classroom, and discussing the extension of these theories. Protocols were collected from an eighth-grade cla35 using the University of Chicago School Mathematics Project algebra text in an urban middle school. Audiotapes were made of student classroom conversations in working groups. Audiotapes from three students are quoted. Analyzing the data provides a framework for a fine-grained theory. Data suggest that in the initial stages of learning algebra, visual clues play a more important role than does syntactic or semantic understanding. Directly related is the importance of examples. Data also suggest that the more novel the problem, the more students are likely to rely on visual clues. Students in the early stages of learning tend to do mathematics problems based on how the symbols are arranged on the page, rather than syntactically deconstructing the expression or the underlying semantics. It is suggested that although a production system architecture is applicable to doing and learning mathematics in the classroom, students do not compose productions as quickly and easily as suggested by some theories.

Towards Creative Lean (Clean) Construction: From Lean Production to Lean Consumption

The current approaches in lean construction are primarily production oriented. More recently, there has been greater attention towards what we design, based on approaches such as Target Value Design. Despite these developments, the need for production is taken as the default starting point in the design explorations. On the other hand, new business models and approaches such as Space-As-A-Service may at times eliminate the need for any production at all, and yet deliver the desired functionalities and values to the target users and customers. Such solutions, based on principles of shared resources and sharing economy can be viewed as ‘Lean consumption mode s that e iminate waste in consumption patterns itself. Since such alternative approaches require divergent thinking, there is need to integrate creative design methodologies in lean construction practice. Therefore, this paper aims to initiate this discussion on Creative Lean (CLean) Construction, as a step from lean production to lean consumption.
Assessment of hurricane's effect on the upper mixed layer of the southwestern Mexican Pacific during ENSO 1997-1998: in situ and satellite observations

Using data from closely spaced CTD profiles and satellite imagery we investigated the effect of hurricane Rick on the sea surface temperature (SST) and the upper mixed layer of the southwestern Mexican Pacific coast. Effects of ENSO 1997-1998 in this region are also discussed by analysing SST maps. Coincident hydrographic measurements were carried out during an oceanographic campaign over the area in November 1997. Results revealed an increment of SST between 3 to 4°C above the climatological mean temperature (25° ± 2°C), in the Mexican Tropical Pacific, during ENSO. In situ measurements show instabilities in the upper mixed layer after the pass of the hurricane in oceanic areas. Satellite and historical databases enabled interpretation and analyses of ENSO's effect on the southwest coast of Mexico.
A decomposition algorithm for N-player games

An N-player game can be decomposed by adding a coordinator who interacts bilaterally with each player. The coordinator proposes profiles of strategies to the players, and his payoff is maximized when players’ optimal replies agree with his proposal. When the feasible set of proposals is finite, a solution of an associated linear complementarity problem yields an equilibrium of the approximate game and thus an approximate equilibrium of the original game. Computational efficiency is improved by using vertices of a triangulation of the players’ strategy space for the coordinator’s pure strategies. Computational experience is reported.
A protein‐based approach to mark arthropods for mark‐capture type research

A series of studies was conducted to test methods for marking a wide variety of arthropods with inexpensive proteins for mark‐capture dispersal research. The markers tested included egg albumin protein in chicken egg whites and casein protein in bovine milk. The first study qualified the effectiveness of the two marks on more than 50 arthropod species inhabiting cotton via two application procedures. The application methods included: (1) a topical plus residue protein application, and (2) a residue‐only protein application. Both protein marks, regardless of the method of application, were readily retained on the arthropod assemblage over the duration of the study. The second study determined how rapidly insects acquire chicken egg albumin protein after contact exposure to cotton tissue sprayed with an egg whites solution. Under laboratory conditions, the vast majority of adult Hippodamia convergens Guérin‐Méneville (Coleoptera: Coccinellidae) and Lygus hesperus Knight (Heteroptera: Miridae) acquired the mark after 5 min, and immature Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) acquired the marker after 40 min. The third study determined how rapidly H. convergens and L. hesperus acquire bovine casein protein after contact exposure to either alfalfa, Medicago sativa L. (Fabaceae), or lesquerella, Lesquerella fendleri (Watson) (Brassicaceae), plants sprayed with a bovine milk solution. These insects rapidly acquired the casein mark from the plant residue under field conditions. A final study determined how long H. convergens retain casein protein after 24‐h exposure to alfalfa and lesquerella plants containing a 7‐day‐old residue of bovine milk. Approximately 95% of the H. convergens maintained the casein mark for 2 days after removal from each type of plant.

In this article, the authors review this growing literature, critique it, and develop some of the research questions that could be explored to contribute to this literature and to the theoretical perspectives that underpin the literature.
Global Inequality, Rising Powers and Labour Standards

The paper analyses growing inequality in the rising powers, concentrating on the situation in China and India. It describes the various processes that are currently underway to reduce inequality in these economies. These processes include a combination of tightening the labour market, as best seen in China, increasing rural productivity and implementing government measures to boost basic rural incomes in all such countries. Reductions in inequality in the emerging economies have a global macro-economic effect of increasing consumption, thus counteracting the current global slowdown. They also have the benefit of creating more space at the bottom for poorer economies to take up more of the world's low-skill production, as the emerging economies themselves move up to higher skill production and exports. This sequential upgrading is being driven by the growth of emerging economy markets and by wage increases in these economies.

Motivation: A Supporting Factor of the Success in Second Language Acquisition

Motivation in second language acquisition is one of the influencing factors that determine the success or failure in mastering the language being studied. Since motivation is personal in nature and its intensity is relative, it needs to be kept constant and then promoted. The teachers in the classroom setting, besides the students themselves, play important roles in maintaining and promoting the intensity of motivation. In order to be able to keep constant and increase the intensity of motivation, the nature of motivation is necessary to be understood in depth.
Remittances and Economic Growth: Larger Impacts in Smaller Countries?

Abstract This paper examines the impact of remittances on economic growth in Small Island Developing States (SIDS). Results from variants of an empirical model suggest that while, on average, there is at best no association between remittances and growth in developing countries, there is a positive association between these variables in SIDS. This finding holds for SIDS in sub-Saharan Africa and the Pacific but not for those in Latin America and the Caribbean. Relationships between remittances, economic volatility, and household labour supply are offered as reasons for these findings.

A framework for acquiring the resources vital for the start-up of a business in South Africa: an African Immigrant's Perspective

Using a triangulation of three methods, we devise a framework for the acquisition of the resources vital for the start-up of a business in South Africa. Against the backdrop of the fact that numerous challenges prohibit African immigrants from starting a business, let alone growing the business, we set out to investigate how those who succeed acquired the necessary resources. Within the quantitative paradigm, the survey questionnaire was used to collect and analyze the data. To compliment the quantitative approach, personal interviews and focus groups were utilised as the methods within the qualitative approach paradigm. The research revealed that an African immigrant entrepreneur is most likely to be a male between the ages of 19 and 41 who has been forced to immigrate by political circumstances. Once in South Africa, limited job opportunities forced these immigrants into starting-up a business. In order of importance, financial, informational, human and physical, resources were identified as being critical for the start-up a business. With respect to the acquisition of resources, African immigrant entrepreneurs unwillingly made use of personal savings to finance their businesses during the start-up phase of the business. Financial resource played a double role in that it determined the main sources of physical resources used. From a human resource perspective, African immigrant entrepreneurs preferred employing South Africans during the start-up phase of the business, and the reverse was true during the growth phase. To a limited extent family labour was involved at both the start-up as well as the operation phases of the business; with formal education and prior experience playing an indirect role as far as the human resources mixed were concerned. In terms of information, African immigrant entrepreneurs made use of two primary sources of information namely; their ethnic networks and friends from somewhere else.
Genetic diversity of lowland sorghum landraces assessed by morphological and microsatellite markers

Genetic diversity is one of the fundamental success factors in plant breeding programs. The objective of this study was to assess the genetic diversity in lowland sorghum landraces using 25 agro-morphological and 30 microsatellite markers. Phenotypic diversity of 267 genotypes originated from Ethiopia was determined using diversity indices, principal component, cluster, and discriminant analyses. High phenotypic diversity indices were recorded, ranging from 0.67 to 1.00, with a mean of 0.88. Principal component analysis and discriminant analyses identified four PCAs and five discriminant functions which contributed 82% and 92% of the total phenotypic variation among the landraces and their respective geographic origin, respectively. The PIC ranged from 0.26 to 0.88, with a mean of 0.61. The mean gene diversity was 0.69, which largely explained variation among genotypes within geographic origin. The SSR markers and phenotypic traits showed similar clustering patters of landraces except some discrepancies. Information obtained in this study may be useful for future sorghum breeding improvement program.
Temporary Commercial Network Programming for Beijing Olympic Games Based on Data Mining and Genetic Algorithms

This paper is committed to the optimization of the temporary commercial network programming for the 2008 Beijing Olympics. It begins with the information extraction from the Assess database of questionnaire investigations based on data mining techniques including cluster analysis and mining of association rules. Based on the discovered knowledge, we calculate customer traffics and shopping demands of the twenty commercial sites and determine the reasonable construction scales of the 20 commercial sites. In order to reach the three objectives of the programming work—meeting shopping demand, balanced distribution, and making profits—we design an optimization model based on genetic algorithms to optimize the construction scale of each site. Finally, a linear programming model is proposed for choosing the appropriate type and corresponding number of supermarket for each of the 20 sites. All the methods in this paper are innovative tools for the quantitative analysis tasks of the decision-making jobs related to the temporary commercial network of the Beijing Olympic Games.
