Career planning orientation of disadvantaged high school boys: a study of socioeconomic and social cognitive variables
Pride and Prejudice: How do they matter to career development?
The notion of a personal career emerged as a response to needs expressed within the western, industrialised culture. This specific expression of human work behaviour appeared at a time in history when approaches to work in the west had been transformed by powerful movements such as the Protestant
Reformation and the Industrial Revolution. By contrast, the idea of choosing a personal career was not intrinsic to the cultural and economic environment that prevailed in non-western contexts at that time in history. Today, however, against the background of westernisation, industrialisation and now globalisation, the situation is quite different. With the rapid breaking down of older social mechanisms for occupational role allocation, questions surrounding career choices, decision-making, and career preparation have become a reality in the developing world as well. The fact remains, though, that career development occurs in a very different manner in these contexts and is influenced by distinctive factors that are specific to these situations
Tool-Supported Data Collection for Experiments to Subjectively Assess Vision Videos
Die Anforderungsermittlung ist eine wichtige Prozess der Anforderungserhebung, da die herausgekitzelten Anforderungen eigentlich in gut festgestellten Anforderungen umgewandelt werden, die dann weiter als Bausteine für ein e zientes Softwareprojekt dienen. Im Bereich von Elicitationstechniken funktionieren Videos als einer der eindeutigste und deskriptive Wege zur Kommunikation vom Problem, der Lösung und der Ergebnisse einer Prozess alles in kurzer Zeit zu den Stakeholdern. Wenn Methoden zur Verbesserung der Qualitätsaspekten der solchen Vision Videos entwickelt werden, wird es auch die Performanzrate der Anforderungserhebungsprozess des geförderten Projekt vielfach erhöhen.
Der in dieser Arbeit entwickelte Werkzeug, Feedback Recorder, zeigt eine Implementation einer detaillierten subjektiven Qualitätsbewertung, die zur Erfassung der potenziellen Videoqualitätsdaten dient, die sonst verliert gehen können. Grundsätzlich speichert das Programm die Qualitätsbewertungen, die während des Laufen des Videos eingegeben wird. Stattdessen normalerweise nur eine solche Bewertung zum Ende des Videos gespeichert wird. Im Zusatz dazu könnte das Werkzeug die gespeicherten Daten unterschiedlicher Teilnehmer eines Versuchs in gra scher Form darstellen. Dies könnte dann auch zum sofortigen Vergleich und der Erkennung der Schwachstellen in den Videos führt. Die Evaluierungsprozess dieser Arbeit handelt sich um das Fördern der Usabilitätsaspekten des Werkzeuges mithilfe von relevanten Metriken.Elicitation of requirements is a crucial process in Requirements Engineering as it is what is chiseled into final requirements that form the building blocks of an efficient software product. Out of the many techniques used to elicit requirements, videos stand out from the rest due to their unique and descriptive way of conveying the problem, solution and the results of a process to the involved stakeholders in a short period of time. When methods are developed to enhance the quality aspects of such Vision Videos, their increased performance would help accelerate the requirements engineering process of the promoted project.
The software tool developed in this thesis, known as Feedback Recorder, presents an implementation of a detailed subjective quality assessment that could be used to collect potentially useful video quality data that might otherwise get lost. The program primarily helps in storing the quality scores of data throughout the length of a video instead of just an objective score at the end of the video. Additionally the tool can also represent results of different participants of an experiments in a graphical form that could help in instant comparison and identification of weak spots in the videos. The evaluation process of this thesis involves promoting the usability aspects of the tool with the measurement of relevant metrics
Soil degradation due to heavy metal accumulation under long term fertilization of paddy (Oryza sativa L.)
Long term fertility experiment (LTFE) under double rice cropping system was investigated in Tamil Nadu Rice Research Institute, Aduthurai, India with two varieties (ADT 43 and ADT 45) in two seasons (Kharif and Rabi) under six fertilizer treatments to study the heavy metal accumulation in soil and its impact on paddy. There was a significant variation in physico-chemical properties of soil due to different fertilizer treatments. The surface soil (0-15cm soil depth) in all the treatments showed relatively higher heavy metal accumulation than subsurface. In thelong run, there was a build up in the total heavy metal content in soil and it was found to be relatively high in phosphatic fertilizer applied treatments than others. Total Cd and Pb was found high, but the availability was below detectable limit indicated that Cd and Pb were found in unavailable forms, while Cu and Zn were slightly in mobile forms which had been translocated into grain and straw of paddy. The DTPA (Diphenyl Triamine Penta Aceticacid) extractable Cd and Pb in the soil was low, but there was heavy increase in Cu and Zn comparing with initial period. The rate of increase in Cd and Pb content was lower in N alone and control plots. This might be due to the long term application of phosphotic and zinc sulphate fertilizers. Cd and Pb were evenly distributed at low concentrations in grain and straw under various treatments. In case of Cu and Zn, it was relatively higher in grains and paddy strawamong various fertilizer treatments. There was no significant difference among the varietal (seasons) treatments for the accumulation of heavy metals in grain and straw
Utilization of flower waste for the removal of chromium from tannery effluent
In this work we used flower waste biomass as a biosorbent to remove Cr from tannery effluent through column experiments. The sorption capacities of biosorbent (Fine, coarse and rough grades) were also evaluated by employing chemical pretreatments viz., sodium hydroxide, acetic acid, glutaraldehyde and hydrogen peroxide. The order of percentage removal of Cr using the above pretreatments was: 10% hydrogen peroxide < Raw powdered-FWB < 2% Gluteraldehyde < 10% Acetic acid < 0.1N sodium hydroxide. Among the different grades of biosorbents used, fine grade adsorbed more Cr (70 %) than that of coarse (64%) and rough (62 %) sorbents. The removal percentage of Cr from tannery was analyzed by using Atomic Absorption Spectroscopy, the functional groups which are responsible for adsorption was examined by Fourier Transform- Infrared Spectroscopy and the amorphous behaviour of FWB facilitating metal biosorption was indicated by the X-ray diffractogram. This study showed that pretreated flower waste biomass is a potential sorbent of Cr, which could be successfully used to reduce the Cr content in tannery effluent
Calcitonin Gene-Related Peptide and Migraine: Implications for Therapy
It is clearly evident from the literature that headache has troubled mankind from the
dawn of civilization (Rapoport & Edmeads, 2000). A variety of methods have been
used throughout the ages in an attempt to alleviate or cure this pain; these may have
been the most appropriate at that time, and were probably seen as “cutting edge”.
Today they seem at best amusing, and at worst cruel and barbaric.
The earliest concepts in migraine were those of the supernatural, with
migraine believed to be due to malevolent beings within the head; treatment based on
this idea included incantations and application to the head of substances intended to
drive out the demons and spirits (Edmeads,
1991). These were also driven out physically,
as in the Neolithic period (8500-7000 BC). The
people living in this time used the method of
trepanation, a kind of neurosurgery, which
involved removing circular chunks of skull so
that the spirits causing the headache could
escape. Over 50% of the trepanned skulls have
shown evidence of healing, indicating a high
survival rate for this operation. Although the
scientific rationale behind trepanation is not
understood, it is surprising that this procedure
was performed as a treatment for migraine as
late as the mid 17th century (Edmeads, 1991;
Rapoport & Edmeads, 2000)
Soil organic carbon assessment under different land uses in Cauvery delta zone of Tamil Nadu, India
Soil organic carbon (SOC) plays a vital role in soil fertility and is important for its contributions to mitigation and adaptation to climate change. The present study was undertaken to estimate the SOC stock in soils under different land uses of Cauvery Delta zone of Tamil Nadu. Four different land uses were selected for the study viz, Forests, Agriculture, Agro-forestry and Plantations. Soil samples were collected from Madukkur and Kalathur soil series of Cauvery Delta zone for soil carbon analysis. The soil samples were fractionated into three aggregate size classes viz., macro-aggregates (250-2000µm), micro-aggregates (53-250 µm) and silt and clay sized fraction (<53 µm). At 0-30 cm depth, the forest land use stored the maximum SOC stock in the different size fractions viz. macro-sized fraction (73.0 Mg ha-1), a micro-sized fraction (76.0 Mg ha-1) and silt+clay sized fraction (77.0 Mg ha-1) in Madukkur series. Agriculture land use registered the lowest SOC stock. Among the different size fractions, silt+clay sized fraction (< 53 µm) retained the maximum SOC in all the land uses. In Kalathur series also, maximum soil organic carbon stock was recorded in forest land use. The data generated in the study will be beneficial to the user groups viz., farmers in identifying the most suitable land use for enhancing the storage of soil organic carbon thereby improving yields of crops and trees
