Socio-economic aspects of cigarette smoking in Malta and Gozo

Questions on smoking behaviour were included in the Census of Population and Housing taken in November 1985. Information was gathered on the number of cigarettes consumed by smokers, those who had stopped smoking and those who had never smoked. Since the Census, smoking has figured prominently in Maltese newspapers and the Health Education unit has been active in publicising the health hazards associated with tobacco dependence. Nevertheless relatively little research has been done on patterns of cigarette smoking and on the demographic, socio-economic and environmental factors that may go some way towards explaining the sharp variations in cigarette addiction within Malta and Gozo. This paper explores a number of these underlying dimensions and using a simple statistical index identifies those neighbourhoods which have high, about average and low levels of smoking behaviour.peer-reviewe

Software and methods for oligonucleotide and cDNA array data analysis.

Two HTML-based programs were developed to analyze and filter gene-expression data: 'Bullfrog' for Affymetrix oligonucleotide arrays and 'Spot' for custom cDNA arrays. The programs provide intuitive data-filtering tools through an easy-to-use interface. A background subtraction and normalization program for cDNA arrays was also built that provides an informative summary report with data-quality assessments. These programs are freeware to aid in the analysis of gene-expression results and facilitate the search for genes responsible for interesting biological processes and phenotypes

The Influence of Intelligence and Other Factors on the Type of Punishment Administered to Children

This report is based on the answers given by twenty-five hundred children in certain Iowa public schools to a brief questionnaire viz: 1. Have you ever been punished at home? (underscore the right word) Yes, often; Seldom; Once only; Never. 2. How were you punished at home? By scolding; slapping; whipping; other ways -_______________________ 3. Have you ever been punished at school? Yes, often; Seldom; Only once; Never. 4. How were you punished at school? Scolding; Slapping; Keeping in; Whipping; Other ways ___________________ 5. If you were a parent or a teacher how would you punish a child? (underscore your choice of ways) Scolding; Take away playtime; No dinner; Send to bed early; Slapping; Whipping; _____________________ This study is concerned only with the answers to No. 2, - How were you punished at home? and the answers to No. 5 - The type of punishment the child would administer if he were a parent or a teacher

Development of an L-, C-, and X-band radar for backscattering studies over vegetation

With the recent surge of interest in global change, the impact of different ecosystems on the Earth's carbon budget has become the focus of many scientific studies. Studies have been launched by NASA and other agencies to address this issue. One such study is the Boreal Ecosystem-Atmosphere Study (BOREAS). BOREAS focuses on the boreal ecosystem in Northern Canada. As a part of the BOREAS study, we have developed a helicopter-borne three-band radar system for measuring the scattering coefficient of various stands within the boreal forest. During the summer of 1994 the radar was used at the southern study area (SSA) in Saskatchewan over the young jack pine (YJP), old jack pine (OJP), old black spruce (OBS) and old aspen (OA) sites. The data collected will be used to study the interaction of microwaves with forest canopy. By making use of three different frequency bands the contribution to the backscatter from each of the layers within the canopy can be determined. Using the knowledge gained from these studies, we will develop algorithms to enable more accurate interpretation of SAR images of the boreal region. This report describes in detail the development of the L-, C- and X-band radar system. The first section provides background information and explains the objectives of the boreal forest experiment. The second section describes the design and implementation of the radar system. All of the subsystems of the radar are explained in this section. Next, problems that were encountered during system testing and the summer experiments are discussed. System performance and results are then presented followed by a section on conclusions and further work

Measurement of a Sign-Changing Two-Gap Superconducting Phase in Electron-Doped Ba(Fe_{1-x}Co_x)_2As_2 Single Crystals using Scanning Tunneling Spectroscopy

Scanning tunneling spectroscopic studies of $Ba(Fe_{1-x}Co_x)_2As_2$ (x = 0.06, 0.12) single crystals reveal direct evidence for predominantly two-gap superconductivity. These gaps decrease with increasing temperature and vanish above the superconducting transition $T_c$. The two-gap nature and the slightly doping- and energy-dependent quasiparticle scattering interferences near the wave-vectors $(\pm \pi, 0)$ and $(0, \pm \pi)$ are consistent with sign-changing $s$-wave superconductivity. The excess zero-bias conductance and the large gap-to-$T_c$ ratios suggest dominant unitary impurity scattering.Comment: 4 pages, 4 figures. Paper accepted for publication in Physical Review Letters.
