Aspects of carbon metabolism in relation to autumnal blade abscission in the kelp Pleurophycus gardneri (Phaeophyceae, Laminariales

Pre-abscission changes in the deciduous kelp Pleurophycus gardneri involve a gradual decrease in dry weight, mannitol and laminaran content. These carbon compounds decreased from about 18% (dry weight) to 4 % prior to blade abscission, while the perennial structures, stipe and holdfast, showed a concomitant increase in mannitol and dry weight towards autumn. In November, at the time of new blade outgrowth, mannitol content peaked in stipe and holdfast with 12 and 18%, respectively. Laminaran accounted for less than 2 % in all thallus parts and showed no measurable seasonal variation. Pigment levels of the blade increased with progressing senescence and were at maximum just prior to blade abscission. The photosynthetic performance of the blade revealed saturating irradiances of about 50pE m-2 S-' and a compensation irradiance of 2.5 to 3 ~ t E m-2 S-' measured in April. h g h t saturation of the stipe was at 38 pE m-2 S-' and of the haptera at 23 pE m-2 S-' while compensation irradiances were at roughly 8 FE m-2 S-' for both perennial parts. It is suggested that new blade outgrowth requires 11ght-carbon fixation. No acropetal translocation of the abundant carbon store of the perennial structures was observed The deciduous habit of P. gardneri reflects a shade-adapted growth strategy. The perennial parts are involved In the overall physiology of the plant and have similar seasonal fluctuations in their constituents to those of the blade. The described growth strategy is novel among perennial kelp species.
Access to ICT as moderating factor to women's participation in the labor force: a conceptual framework.

— This study focuses on the development of the conceptual framework explaining the participation of women in the labor market with a particular interest on the role of Information Communication and Technology (ICT). Various studies have found that women's participation in the labor market can be triggered by the many factors. Almost all studies stated that the involvement of women in the labor force normally is associated with economic, socio-demographic and cultural factors. In this technological age, there is a notion that the ICT also plays an important role in determining a woman's decision to work. ICT enables workers to do their job more efficiently, saving both time and monetary costs. ICT may contribute to women participation in the labor market through provision of better access to job market information. In addition it provides women with greater flexibility by allowing them to work from home. For an organization, the monitoring system for the efficient ICT infrastructure and high accessibility, may allow women doing her job at home. Nonetheless there are challenges remain to be addressed particularly in the case of Malaysia as a great disparity in the accessibility of ICT, especially in rural areas.

The Hausa "Grade 5/Causative-Efferential" Verb: Causative, Noncausative, or Both? A Critical Assessment Of Previous Analyses

This critical review evaluates various semantic classifications of the so-called derivative "Grade 5" Hausa verb. Members of this morphologically distinct class are all transitive but express a diverse range of meanings, e.g., kwantar = Grade 5 ‘lay (down)’ < intransitive kwântaa ‘lie (down)’, sayar = Grade 5 ‘sell’ < transitive sayaa ‘buy’, jeefar = Grade 5 ‘throw away’ < transitive jeefaa 'throw’. Previous analyses have attempted to explain these interpretations in terms of a semantic causative and/or noncausative framework. In this paper, I conclude that both the 'lie/lay' and "caused-change-of-possession" 'buy/sell' verb-pairs represent stereotypic causative alternations, as distinct from the 'throw/throw away' "change of location" class which falls short of expressing causation.
The effect of ising either abstractor Concrete

The effect on verbal problem solving from using either abstract or concrete words was examined. Twe/ve undergraduate students in each of the two conditions mentally solved identically structured problems by reordering and chaining together previously memorized pairs of words. Subjects who received concrete words both memorized the word pairs and solved the problems in less time than did subjects who received abstract word pairs. Superior performance associated with concrete words was analyzed in relation4to the facilitating effect of imaginal over verbal encoding. Implications were
Structure function analysis of SH 2 D 2 A isoforms expressed in T cells reveals a crucial role for the proline rich region encoded by SH 2 D 2 A exon 7

Background: The activation induced T cell specific adapter protein (TSAd), encoded by SH2D2A, interacts with and modulates Lck activity. Several transcript variants of TSAd mRNA exist, but their biological significance remains unknown. Here we examined expression of SH2D2A transcripts in activated CD4+ T cells and used the SH2D2A variants as tools to identify functionally important regions of TSAd. Results: TSAd was found to interact with Lck in human CD4+ T cells ex vivo. Three interaction modes of TSAd with Lck were identified. TSAd aa239–256 conferred binding to the Lck-SH3 domain, whereas one or more of the four tyrosines within aa239–334 encoded by SH2D2A exon 7 was found to confer interaction with the Lck-SH2-domain. Finally the TSAd-SH2 domain was found to interact with Lck. The SH2D2A exon 7 encoding TSAd aa 239–334 was found to harbour information essential not only for TSAd interaction with Lck, but also for TSAd modulation of Lck activity and translocation of TSAd to the nucleus. All five SH2D2A transcripts were found to be expressed in CD3 stimulated CD4+ T cells. Conclusion: These data show that TSAd and Lck may interact through several different domains and that Lck TSAd interaction occurs in CD4+ T cells ex vivo. Alternative splicing of exon 7 encoding aa239–334 results in loss of the majority of protein interaction motives of TSAd and yields truncated TSAd molecules with altered ability to modulate Lck activity. Whether TSAd is regulated through differential alternative splicing of the SH2D2A transcript remains to be determined.

Star formation in the massive cluster merger Abell 2744

We present a comprehensive study of star-forming (SF) galaxies in the Hubble Space Telescope (HST) Frontier Field recent cluster merger A2744 (z = 0.308). Wide-field, ultraviolet-infrared (UV-IR) imaging enables a direct constraint of the total star formation rate (SFR) for 53 cluster galaxies, with SFRUV+IR = 343 ± 10 M⊙ yr-1. Within the central 4 arcmin (1.1 Mpc) radius, the integrated SFR is complete, yielding a total SFRUV+IR = 201 ± 9 M⊙ yr-1. Focusing on obscured star formation, this core region exhibits a total SFRIR = 138 ± 8 M⊙ yr-1, a mass-normalized SFRIR of ΣSFR = 11.2 ± 0.7 M⊙ yr-1 per 1014 M⊙ and a fraction of IR-detected SF galaxies f_SF = 0.080^{+0.010}_{-0.037}. Overall, the cluster population at z ˜ 0.3 exhibits significant intrinsic scatter in IR properties (total SFRIR, Tdust distribution) apparently unrelated to the dynamical state: A2744 is noticeably different to the merging Bullet cluster, but similar to several relaxed clusters. However, in A2744 we identify a trail of SF sources including jellyfish galaxies with substantial unobscured SF due to extreme stripping (SFRUV/SFRIR up to 3.3). The orientation of the trail, and of material stripped from constituent galaxies, indicates that the passing shock front of the cluster merger was the trigger. Constraints on star formation from both IR and UV are crucial for understanding galaxy evolution within the densest environments.
The Effectiveness of Instructional Games: A Literature Review and Discussion

Abstract : This report documents a review of 48 empirical research articles on the effectiveness of instructional games. It also includes summaries of 26 other review articles and 31 theoretical articles on instructional gaming. Eased on this review the following 5 conclusions and 4 recommendations are provided. Conclusions: (1) The empirical research on the instructional effectiveness of games is fragmented, filled with ill defined terms, and plagued with methodological flaws. (2) Some games provide effective instruction for some tasks some of the time, but these results may not be generalizable to other games or instructional programs. (3) No evidence indicates that games are the preferred instructional method in all situations. (4) Instructional games are more effective if they are embedded in instructional programs that include debriefing and feedback. (5) Instructional support during play increases the effectiveness of instructional games. Recommendations: (1) The decision to use a game for instruction should be based on a detailed analysis of learning requirements and tradeoffs among alternate instructional approaches. (2) Program managers and procurement officials should insist that instructional game developers demonstrate how their game will support instructional objectives. (3) Games should be used as adjuncts and aids, not as stand-alone instruction. (4) Instructor-less a roaches (e.g., web-based instruction) must include all "instructor functions. "
Supply chain disruptions: Insights from South African third-party logistics service providers and clients

Background: Despite risk management efforts, supply chains have become increasingly vulnerable to disruptions. Disruptions should be successfully managed if organisations are to thrive in today’s ever-changing world.Purpose: This study explored supply chain disruptions of third-party logistics service providers (3PLs) and their clients based in South Africa by investigating the disruptions these organisations face, and how they go about managing them.Method: A generic qualitative research approach was used to gather data by conducting semi-structured interviews with 22 participants, which comprised 11 3PLs and 11 client organisations operating in South Africa.Findings: This study classified disruptions as intra-, inter- and extra-organisational. South African 3PLs and their clients face the majority of their disruptions either intra- or inter-organisationally. The focus of 3PLs and clients has shifted from risk management to disruption management. The findings show that 3PLs and their clients based in South Africa prefer disruption learning over traditional risk management as a method to better manage future disruptions.Conclusion: This study contributes to existing literature by providing insight into the specific supply chain disruptions that 3PLs and their clients based in South Africa face, according to the disruption location in the supply chain and how 3PLs and clients manage supply chain disruptions.
Cut-Free Proof Systems for Geach Logics

This text is expository. We explain Gödel’s ‘Master Argument’ for incompleteness as distinguished from the ‘official’ proof of his 1931 paper, highlight its attractions and limitations, and explain how some of the limitations may be transcended by putting it in a more abstract form that makes no reference to truth.
Coinfection in Patients with Lyme Disease : How Big a Risk ?

Sir—We appreciate the comments of Hung and Hsiao [1] on our recent article [2]. We agree that the epidemiologic characteristics of the subjects will significantly affect the prevalence of isolated hepatitis B core antigen (anti-HBc) in a population. However, we are not certain how to interpret their results because of a number of discrepancies in the table of data in their letter. Hung and Hsiao [1] report that 98 subjects in their study have chronic hepatitis B virus (HBV) infection (that is, that they have test results that are positive for hepatitis B surface antigen (HBsAg), negative for antibody to hepatitis B surface antigen [anti-HBs], and positive for antiHBc). They calculate the prevalence of chronic HBV infection to be 13.7% (98 of 716 subjects), but we believe that the true prevalence should be 23.6% (98 of 416 subjects), because the authors indicate that only 416 subjects were tested. Similar discrepancies affect the prevalence of HBV infection among subjects in the other groups discussed in their analysis. In addition, for group 4, the number of subjects classified by CD4 cell count category (10 subjects with a CD4 cell count of ! 50 cells/ mm, 16 subjects with 50–99 cells/mm, 3 subjects with 100–199 cells/mm, 5 subjects with 200–349 cells/mm, and 3 subjects with 1350 cells/mm) does not add up to the 27 subjects classified as being in group 4. Thus, it is difficult to fully evaluate their results because of these discrepancies. The cohort described by Hung and Hsiao [1] has a lower prevalence of HCV infection than our cohort. In fact, only 1 subject in their study had both positive test results for HCV infection and negative test results for HBsAg, anti-HBs, and antiHBc, and only 12 subjects who tested positive for HCV had isolated anti-HBc. With such low numbers, we do not believe their study would have the power to allow them to detect an association between HCV infection and the isolation of anti-HBc. Finally, the median CD4 cell count among their subjects with isolated anti-HBc does not differ from that among subjects with negative test results for HBsAg, anti-HBs, and anti-HBc, which agrees with our findings.

Assimilates allocation in fruits and leaves of coffee plants cultivated in two altitudes

The objective of this work was to evaluate the allocation of carbohydrates in fruits of Arabic coffee plant during the period comprised among the anthesis and maturation in two different altitudes, as well as, the variation in its content in leaves of these productive branches. The experiment was constituted of the coffee plant variety (Coffea arabica L.) Catuaí IAC-44 cultivated at 720 and 950 m above the sea level in Martins Soares, Minas Gerais State, Brazil. The experimental design was completely randomized with three repetitions using splitplot in time scheme. The altitude of 720 m contributed to an acceleration in the accumulation of starch, total soluble sugar, reducing sugar and non-reducing sugar in coffee plant fruits. The accumulation of starch in the altitude of 720 m preceded the accumulation in the altitude of 950 m, presenting larger earning percentage in the fruit fast expansion stadium. In this stadium, carbohydrate concentrations in leaves in the 3 and 4 leave pairs of productive branches decreased abruptly indicating that this is the most critic period for the carbohydrate concentrations in leaves. Altitude influenced the extension of the cycle, as well as the assimilate accumulation by fruits and that variation in coffee plant leaves.
Print media reportage of agricultural biotechnology in the Philippines: a decade’s (2000-2009) analysis of news coverage and framing

This article presents key results of a ten-year study of media coverage of agricultural biotechnology in the Philippines, the only country in Asia to date to approve a biotech food/feed crop (Bt corn) for commercialization. The top three national English newspapers - Manila Bulletin, Philippine Daily Inquirer, and Philippine Star were analyzed to determine patterns of media attention measured by coverage peaks, tone, source of news, keywords, and media frames used. Biotechnology news was generally positive but not high in the media agenda. News coverage was marked by occasional peaks brought about by drama and controversial events which triggered attention but not long enough to sustain interest. The study provides a glimpse into the role of mass media in a developing country context. It shows how a complex and contentious topic is integrated into the mainstream of news reporting, and eventually evolves from an emotional discourse to one that allows informed decision making.
SN 1987A after 18 Years: Mid-Infrared Gemini and Spitzer Observations of the Remnant

Using the Gemini South 8 m telescope, we obtained high-resolution 11.7 and 18.3 μm mid-IR images of SN 1987A on day 6526 since the explosion. All the emission arises from the equatorial ring. Nearly contemporaneous spectra obtained at 5-38 μm with the Spitzer Space Telescope show that this is thermal emission from silicate dust that condensed out in the red giant wind of the progenitor star. The dust temperature is 166 K, and the emitting dust mass is 2.6 × 10-6 M☉. Comparison of the Gemini 11.7 μm image with Chandra X-ray images, HST UV-optical images, and ATCA radio synchrotron images shows generally good correlation across all wavelengths. If the dust resides in the diffuse X-ray-emitting gas then it is collisionally heated. The IR emission can then be used to derive the plasma temperature and density, which were found to be in good agreement with those inferred from the X-rays. Alternatively, the dust could reside in the dense UV-optical knots and be heated by the radiative shocks that are propagating through the knots. In either case the dust-to-gas mass ratio in the CSM around the supernova is significantly lower than that in the general interstellar medium of the LMC, suggesting either a low condensation efficiency in the wind of the progenitor star or the efficient destruction of the dust by the SN blast wave. Overall, we are witnessing the interaction of the SN blast wave with its surrounding medium, creating an environment that is rapidly evolving at all wavelengths.
Fanconi anemia-D 1 due to homozygosity for the BRCA 2 gene Cypriot founder mutation : A case report

Fanconi anemia (FA) is a rare disorder characterized by multiple congenital malformations, progressive bone marrow failure and susceptibility to malignancies. Biallelic mutations in the breast cancer 2, early onset (BRCA2) gene are responsible for the FA-D1 subgroup, which accounts for ~3% of all the FA cases. Patients with biallelic BRCA2 mutations generally display a more severe phenotype, with earlier onset and increased incidence of leukaemia and other solid tumors, than other patients with FA. In the present report, the first Cypriot patient with FA-D1 is described, which is the fifth case of a homozygote for the same null allele reported thus far, and the third known case of neuroblastoma in association with FA-D1.

Application of LPV methods for improving the qualitative performances of integrated vehicle control

The thesis proposes a reconfigurable integrated control design method for a driver assistance system. In the operation of the system a predefined trajectory required by the driver is followed. During maneuvers the control system generates differential brake moment and auxiliary front wheel steering angle and modifies the camber angles of the wheels in order to improve the tracking of the road trajectory. The performance specifications are guaranteed by the local controllers, i.e., the steering, the braking and the variable-geometry suspension system, while the coordination of these components is provided by the reconfigurable integrated vehicle control strategy. The advantage of the decentralized control architecture is the independent design of local controllers. The interaction between local systems is guaranteed by a reconfiguration strategy. In local control design the parameter-dependent Linear Parameter Varying (LPV) method, which meets the performance specifications, is used. The reconfiguration strategy is based on the monitoring signals, which are taken into consideration in the formulation of the local controller performance specifications. The reconfigurable structure is also able to handle actuator degradation and faults, since the detected fault signals are built into the reconfiguration strategy. The proposed novel integrated vehicle control structure also incorporates a driver model, by which the dynamics of human driver is considered in the control design. The operation of the control system is illustrated through different normal and emergency vehicle maneuvers using the high-accuracy CarSim simulation software. These contributions have been published in international journals and conference papers.
