TEXTBOOK EVALUATION: AN ANALYSIS OF LISTENING AND READING SKILL IN PROJECT LEVEL 1 (4 TH 77 EDITION) AND ACHIEVERS A1+
The present study evaluates the presentation of listening andreading skills in Project level 1 (4th edition) and Achievers A1+ textbooks.The textbooks were evaluated by using the theoretical framework asproposed by Cunningsworth (1995). This research used qualitative contentanalysis as its research method. The results of this study show that bothtextbooks met the evaluation criteria proposed by Cunningsworth (1995)regarding the presentation of the listening skill. As for the presentation ofthe reading skill, Project level 1 (4th edition) textbook was considered asadequately met the requirement; while Achievers A1+ might be morerelevant to the evaluation criteria
Comparative Evaluation of Speaking and Writing Skills in Project Level 1 (4th Edition) and Achievers A1+
This study is intended to find out about the two basic skills which are speaking and writing skill presented in Project level 1 (4th edition) and Achievers A1+ textbook. The textbooks were evaluated by using the theoretical framework as proposed by Cunningsworth (1995). 4 criteria were used to evaluate the presentation of the speaking skill and 9 criteria were used to examine the writing sections. The findings of this study show some interesting similarities and differences that both textbooks have on the presentation of speaking and writing skills
Initial beam-profiling tests with the NML prototype station at the Fermilab A0 Photoinjector
The beam-profile diagnostics station prototype for the superconducting rf
electron linac being constructed at Fermilab at the New Muon Lab has been
tested. The station uses intercepting radiation converter screens for the
low-power beam mode: either a 100-\mu m thick YAG:Ce single crystal
scintillator or a 1-\mu m thin Al optical transition radiation (OTR) foil. The
screens are oriented with the surface perpendicular to the beam direction. A
downstream mirror with its surface at 45 degrees to the beam direction is used
to direct the radiation into the optical transport. The optical system has
better than 20 (10) \mu m rms spatial resolution when covering a vertical field
of view of 18 (5) mm. The initial tests were performed at the A0 Photoinjector
at a beam energy of ~15 MeV and with micropulse charges from 25 to 500 pC for
beam sizes of 45 to 250 microns. Example results will be presented.Comment: 3 pp. Particle Accelerator, 24th Conference (PAC'11) 2011. 28 Mar - 1

Modulation of Cox-1, 5-, 12- and 15-Lox by popular herbal remedies used in southern Italy against psoriasis and other skin diseases.
Acanthus mollis (Acanthaceae), Achillea ligustica, Artemisia arborescens and Inula viscosa (Asteraceae) are used in Southern Italy against psoriasis and other skin diseases that occur with an imbalanced production of eicosanoids. We here assessed their in vitro effects upon 5-, 12-, 15-LOX and COX-1 enzymes as well as NFκB activation in intact cells as their possible therapeutic targets. All methanol crude extracts inhibited both 5-LOX and COX-1 activities under 200 µg/mL, without significant effects on the 12-LOX pathway or any relevant in vitro free radical scavenging activity. NFκB activation was prevented by all extracts but A. mollis. Interestingly, A. ligustica, A. arborescens and A. mollis increased the biosynthesis of 15(S)-HETE, an anti-inflammatory eicosanoid. A. ligustica (IC50 =49.5 µg/mL) was superior to Silybum marianum (IC50 =147.8 µg/mL), which we used as antipsoriatic herbal medicine of reference. Its n-hexane, dichloromethane and ethyl acetate fractions had also inhibitory effects on the LTB4 biosynthesis (IC50 s=9.6, 20.3 and 68 µg/mL, respectively) evidencing that the apolar extracts of A. ligustica are promising active herbal ingredients for future phytotherapeutical products targeting psoriasis
The importance of colour on the communication of financial data in management
Purpose – The purpose of this paper is to explore the importance of colour on the communication of financial
data in management and to encourage future discussion on related topic.
Design/methodology/approach – Hypothesis was designed building on relevant literatures. Quantitative
discrete data were collected through a mini-test activity in a lecture from students. The results were reviewed
and evaluated by relevant statistical tool.
Findings – The authors found consistent statistical significance results in the mini-test. The findings support
that users prefer to choose the financial data presented in cool colours in business management context.
Research limitations/implications – Gaining the understanding of colour’s influence on decision making
and behaviour is subjected to complexity. There are many other contextual factors should be taken into
consideration in practice. Although the design of the mini-test in this study is relatively simple, it still
provides clues for the issue. With the discussions and findings of this paper, the authors shed some light on
the direction of potential uses of colour on the communication of financial data in management context. The
findings could also be used by management educators to facilitate related discussions among students
regarding the complexity of business communication and the importance of perception in decision making.
For example, decision making could be affected by various factors (such as colour) outside verbal and text.
Originality/value – Managers often need to use financial data in communication for various purposes in
work place. The authors believe this is the first time that a study like this had been conducted to specifically
review and discuss the importance of colour on the communication of financial data in management.
Hopefully, the work reported in this paper could be viewed as reference for management educators,
researchers and managers in future research or practical applications on related topics

and the Constructivist Perspective of Mark Savickas. It is also intended to contribute
to the research on the Career Adapt-Abilities Inventory, which is still under
investigation as part of an International Project.
The Career Concerns Inventory and the Career Adapt-Abilities Inventory were
applied to a sample of 75 adult candidates to Sergeants and Officers of the Portuguese
Army. The results seem to confirm the research hypotheses, pointing to the relation
between the variable age and the developmental tasks of the Exploration and
Establishment career phases, to the predominance of the dimensions Cooperation, and
Confidence and also to the relation between career concerns and adaptability
dimensions. The findings of this study, some of its limitations and future research
paths are presented. Some reflections are also discussed in what concerns the study's
implications for the career management practices
Determinants of formation of aflatoxin-albumin adducts: a seven-township study in Taiwan
Dietary exposure to aflatoxins is one of the major risk factors for hepatocellular carcinoma. Individual susceptibility to aflatoxin-induced hepatocarcinogenesis may be modulated by both genetic and environmental factors affecting metabolism. A cross-sectional study was performed to evaluate determinants of the formation of aflatoxin covalently bound to albumin (AFB1-albumin adducts). A total of 474 subjects who were free of liver cancer and cirrhosis and were initially selected as controls for previous case–control studies of aflatoxin-induced hepatocarcinogenesis in Taiwan, were employed in this study. Aflatoxin-albumin adducts were determined by competitive enzyme-linked immunosorbent assay, hepatitis B surface antigen and antibodies to hepatitis C virus by enzyme immunoassay, as well as genotypes of glutathione S-transferase M1-1 and T1-1 by polymerase chain reaction. The detection rate of AFB1-albumin adducts was significantly higher in males (42.5%) than in females (21.6%) (multivariate-adjusted odds ratio=2.6, 95% confidence interval=1.4–5.0). The formation of detectable albumin adducts was moderately higher in hepatitis B surface antigen carriers (42.8%) than in non-carriers (36.6%) (multivariate-adjusted odds ratio=1.4, 95% confidence interval=1.0–2.1). In addition, the detection rate of AFB1-albumin adducts tended to increase with the increasing number of null genotypes of glutathione S-transferase M1-1 and glutathione S-transferase T1-1. In conclusion, this cross-sectional study has assessed the relative contributions of environmental exposure and host susceptibility factors in the formation of AFB1-albumin adducts in a well characterised Chinese adult population. This study further emphasises the necessity to reduce aflatoxin exposure in people living in an area endemic for chronic hepatitis B virus infection
