The effectiveness of the International Ship and Port Facility Security Code (ISPS) in Nigeria

Over the years, acts of insecurity, lack of safety consciousness and threat of terrorism have pervaded the maritime landscape of the world economy. The obvious dishonest outlook and fraud-like tendencies which over the years, have formed the most basic characteristics of the maritime industry have never helped matters either way, but has indeed complicated the issue of high insecurity of the port industries worldwide. The amendment of the Convention on Safety of Life at Sea (SOLAS) introduced the International Ship and Port Facility Security Code (ISPS) code) as preventive measure against the likelihood of terrorist attacks on Ships and Port Facilities

The Relationship between Placement of Female Teachers and Academic Performnace of Secondary School Students in Owerri Urban of Imo State

This research focused on the relationship between placement of Women Teachers and Academic Performance of Secondary School Students in Owerri Urban of Imo State. Descriptive research design was adopted in carrying out the study. A random sampling technique was used to select ten (10) secondary schools used in the study out of twenty secondary schools in Owerri Urban of Imo state. Questionnaire was developed to collect primary data. The data collected was analyzed using the simple percentage method. It ascertained whether there are more female teachers in the Owerri Urban Secondary Schools than their male counterparts thereby assessing the role of women teachers to the education of the students, vis-à-vis their academic performance. In pursuance of the objectives, some hypotheses were stated as seen in chapter 1. A total of twelve schools (12) were sampled with twenty five (25) principals and vice principals, some classroom teachers and officials of the Secondary Education Management Board Owerri Zone as respondents. Data was collected through the use of questionnaires, oral interviews and personal observations respectively. From the findings as reflected in chapter five (5), it was concluded that although many variables are contributory to the excellent and poor performance of students, the posting of many women teachers in a School lowers teachers/school productivity and consequently affects adversely the student’s academic performance.  In order to improve the standard of education and this development in particular, some recommendations were made among which among them was government review of the policy of posting married women teachers within the areas their husbands are working to avoid over-concentration of women teachers in the urban Secondary Schools.

EXERTION LEVEL AND THE INTENSITY OF ASSOCIATED MOVEMENTS

Associated movements in the contralateral limbs were measured quantitatively for 42 seven- to eight-year-old children who wrote with the right hand. Associated movements of the contralateral homologous muscles systematically increased as a function of the intensity of contraction of the active hand. The associated movements were more intense when the left hand was active. The order of hand use markedly affected the lateral asymmetry, indicating that the right and left hands were affected differentially by previous activity. Associated movements of the contralateral antagonist muscles were also observed, and their frequency varied as a function of active hand and exertion level. RÉSUMÉ Les mouvements associÉs des membres contro-latÉraux ont ÉtÉÉtudiÉs quantitativement chez 42 enfants ÂgÉs de sept ou huit ans Écrivant avec la main droite. Les mouvements associtÉs des muscles controlatÉraux homologues augmentaient systÉmatiquement en fonction de l'intensitÉ de la contraction dans la main active. Les mouvements associtÉs Étaient plus intenses lorsque la main gauche Était active. L'ordre d'utilisation de la main affectait de faÇon marquÉe l'asymÉtrie latÉrale, indiquant que les mains droite et gauche Étaient affectÉes diffÉremment par l'activitÉ antÉrieure. Les mouvements associÉs des muscles antagonistes contralatÉraux ont ÉtÉ aussi observÉs et leur frÉquence variait en fonction de la main active et du niveau d'activitÉ. ZUSAMMENFASSUNG Bei 42 sieben- bis achtjÄhrigen Kindern, die mit der rechten Hand schrieben, wurden die assoziierten Bewegungen der kontralateralen Seite quantitativ gemessen. Die assoziierten Bewegungen der kontralateralen homologen Muskeln nahmen systematisch als eine Funktion des Kontraktionsgrades der aktiven Hand zu. Die assoziierten Bewegungen waren intensiver, wenn die linke Hand aktiv war. Die Reihenfolge des Handgebrauchs beeinflußte deutlich die laterale Asymmetrie, was anzeigt, daß die rechte und linke Hand durch vorausgegangene AktivitÄt unterschiedlich beeinflußt wurden. Es wurden auch assoziierte Bewegungen der kontralateralen Antagonisten beobachtet, ihre Frequenz wechselte als eine Funktion der aktiven Hand und des Anspannungsgrades.

The Role of Attention in the Regulation of Associated Movement in Children

The effect of attentional processes in regulating associated movement was studied in 10 male children in each of five age-groups from six to 16 years. They were asked to squeeze their index finger and thumb to 75 per cent of their own maximal volitional force under three conditions: a spontaneous baseline condition, a sensory feedback condition and a post-training condition without sensory feedback. Children of all ages were able to reduce the magnitude of associated movements during the sensory feedback condition. In the post-training condition some of the ability to inhibit was lost, particularly for the six-year-olds. This supports the view that the integration of higher order processes, such as attention, with lower-level neuromotor inhibitory mechanism, plays a role in the reduction of associated movement with increasing age. Implications for therapy with clinical populations are discussed.

On leur demanda d'appuyer leur index sur leur pouce, 75 pour cent de la force maxima, dans trois situations: une situation spontan e de r f rence, une situation de feed-back sensoriel et une situation en post-apprentissage sans feed-back sensoriel. Les enfants de tous ges pouvaient diminuer l'amplitude des mouvements associ s durant la situation de feed-back sensoriel. Dans la situation de post-apprentissage, une partie de la capacit d'inhibition fut perdue, notamment six ans.

Les cons quences pour le traitement d'une population pathologique, sont discut es. ZUSAMMENFASSUNG Die Bedeutung der Aufmerksamkeit f r die Kontrolle von Begleitbewegungen bei Kindern Bei je 10 Jungen aus f nf Altersgruppen wurde die Bedeutung der Aufmerksamkeit f r die Kontrolle von Begleitbewegungen untersucht. Sie mu ten ihren Zeigefinger und Daumen zu 75 Prozent ihrer maximalen willk rlichen Kraft unter drei Versuchsbedingungen zusammendr cken: spontane Basiskondition, sensorische Feedback Kondition und Post-Training Kondition ohne sensorisches Feedback. Kinder aller Altersgruppen waren in der Lage, bei der sensorischen Feedback Kondition die Begleitbewegungen zu reduzieren. Bei der Post-Training Kondition war ein Teil der inhibitorischen F higkeit, besonders bei den Sechs-j hrigen, verlorengegangen. Dies spricht f r die Annahme, da die Integration bergeordneter Prozesse, wie z.B der Aufmerksamkeit, zu untergeordneten neuromotorisch-inhibitorischen Mechanismen f r die Reduzierung von Begleitbewegungen eine Rolle spielt. Die sich daraus ergebenden R ckschl sse f r die Therapie von Patienten werden diskutiert.

Age Differences In The Magnitude Of Associated Movement

Using a quantitative measure of unintended mirror-movements in the contralateral limb during a unimanual task, the magnitude of associated movement across the ages from six to 16 years was determined. Male children in five age-groups (means 6.5, 8.5, 10.4, 12.4 and 16.5 years) were asked to squeeze their index finger and thumb together to various percentages of their own maximal volitional force. Results indicate that the 6.5-year-old group differ from all other age-groups, exhibiting significantly greater associated movements at all levels of force. The results are discussed in terms of the development of inhibitory control over innate neuromotor synergies.

Gaming when things get tough? Examining how emotion regulation and coping self-efficacy influence gaming during difficult life situations

Research suggests that gaming can play an important role in dealing with life difficulties, but few studies have examined this directly. Building on recent research, the current study set out to develop a measure of gaming in difficult life situations (GDLS) and explored the role of emotion regulation and coping self-efficacy as predictors of this behaviour. A total of 667 gamers completed the online survey. Initial analyses demonstrated validity and reliability of the GDLS scale (α=.92), with players turning to gaming as a distraction from life difficulties, to feel a sense of achievement, to connect with others, and for in-game connection and simulation. Multiple regression analysis showed that younger age, more time spent gaming in general, and lower coping self-efficacy predicted gaming in difficult life situations, but emotion regulation was non-significant. The study presents novel insights and a new measure for future research in this area

Timing of a Young Mildly Recycled Pulsar with a Massive White Dwarf Companion

We report on timing observations of the recently discovered binary pulsar PSR J1952+2630 using the Arecibo Observatory. The mildly recycled 20.7-ms pulsar is in a 9.4-hr orbit with a massive, M_WD > 0.93 M_sun, white dwarf (WD) companion. We present, for the first time, a phase-coherent timing solution, with precise spin, astrometric, and Keplerian orbital parameters. This shows that the characteristic age of PSR J1952+2630 is 77 Myr, younger by one order of magnitude than any other recycled pulsar-massive WD system. We derive an upper limit on the true age of the system of 50 Myr. We investigate the formation of PSR J1952+2630 using detailed modelling of the mass-transfer process from a naked helium star on to the neutron star following a common-envelope phase (Case BB Roche-lobe overflow). From our modelling of the progenitor system, we constrain the accretion efficiency of the neutron star, which suggests a value between 100 and 300% of the Eddington accretion limit. We present numerical models of the chemical structure of a possible oxygen-neon-magnesium WD companion. Furthermore, we calculate the past and the future spin evolution of PSR J1952+2630, until the system merges in about 3.4 Gyr due to gravitational wave emission. Although we detect no relativistic effects in our timing analysis we show that several such effects will become measurable with continued observations over the next 10 years; thus PSR J1952+2630 has potential as a testbed for gravitational theories.Comment: 12 pages, 10 figures, to be published in MNRA

The GREAT triggerless total data readout method

Recoil decay tagging (RDT) is a very powerful method for the spectroscopy of exotic nuclei. RDT is a delayed coincidence technique between detectors usually at the target position and at the focal plane of a spectrometer. Such measurements are often limited by dead time. This paper describes a novel triggerless data acquisition method, which is being developed for the Gamma Recoil Electron Alpha Tagging (GREAT) spectrometer, that overcomes this limitation by virtually eliminating dead time. Our solution is a total data readout (TDR) method where all channels run independently and are associated in software to reconstruct events. The TDR method allows all the data from both target position and focal plane to be collected with practically no dead-time losses. Each data word is associated with a timestamp generated from a global 100-MHz clock. Events are then reconstructed in real time in the event builder using temporal and spatial associations defined by the physics of the experimen
