Technological, Organizational, and Environmental Antecedents to Web Services Adoption

The proliferation of web services within the last two years enables organizations to assimilate software and services from different companies and locations into an integrated service capable of streamlining important processes. Widespread adoption of web services has not yet occurred across all industries. To better understand the key determinants of web services adoption at the firm level, a conceptual model of factors impacting web services adoption was developed. The conceptual model was grounded in the technology-organization-environment (TOE) framework (Tomatzky and Fleischer, 1990) to support the formulation of eleven propositions that may affect adoption and continued utilization of web services. Specifically, factors for each of the contexts within the TOE framework were formulated and supported including: (1) technological factors (security concerns; reliability; deployability); (2) organizational factors (firm size; firm scope; technological knowledge; perceived benefits); and, (3) environmental factors (competitive pressure; regulatory influence; dependent partner readiness; trust in the web service provider). A summary of the relationships between the key constructs in the model and recommendations for future research are provided

A group decision support system idea consolidation tool

Manual consolidation of ideas generated in a Group Decision Support System meeting can be a lengthy, inaccurate, and dissatisfying process. The objective of this paper is to demonstrate how an automatic idea consolidation program can reduce the time needed by group members to aggregate comments, inaccuracies of these comment groupings, and dissatisfaction with the comment consolidation process. A case study comparing the program\u27s results with those of two human subjects shows a time savings of 98.8%. Although the computer\u27s comment groupings were not identical with those of the subjects, they were logically consistent

Present study demonstrated that FK 506 at the dose and time periods (1 mg / kg over 7 or 28 days impair the rat tissue based organic constituents, FK 506 depleted the rat tissue total protein, carbohydrate, lipid and glycogen contents of all rat tissues selected for the present study and whereas the same FK 506 treatment enhanced the rat tissues FAA and FFA contents: compared to saline treated rat control tissues. The overall data it is evident that FK 506 administration in the present study impairs the overall general metabolism of rat tissues

Some glimpses of the marine fisheries in Andhra pradesh

Andhra Pradesh stands 5th in the marine fish production among the maritime states of India. The advent of mechanisation of fishing craft and introduction of mechanised fishing vessels have brought significant changes in the marine fishing industry of Andhra Pradesh. As a result of this, the fisheries harbour at Visakhapatnam has become one of the key harbours for mechanised trawl fishing and Visakhapatnam itself has emerged as one of the most important centres for exporting marine products to foreign countrie

A POSSIBLE TSUNAMI IN THE LABRADOR SEA RELATED TO THE DRAINAGE OF GLACIAL LAKE AGASSIZ ~8400 YEARS B.P.

For thousands of years, the thick Laurentide Ice Sheet covered a large part of northern North America, damming northward-draining rivers. As this ice retreated, large lakes formed along its margin. Glacial Lake Agassiz was the largest of these ice-marginal lakes, covering an area of >800,000 km2 (more than twice the size of the largest lake in the modern world, the Caspian Sea) before it drained catastrophically into the Labrador Sea. Even before that, Lake Agassiz had periodically released large volumes of water into the ocean via the Great Lakes-St. Lawrence and the Athabasca-Mackenzie River systems. The last and largest of these outbursts released >150,000 km3 through Hudson Bay and Hudson Strait in 6-12 months; the average flux over that period was ~5 Sv (1 Sv = 1×106 m3s-1).When a volume of water this large is discharged into a coastal sea like the Labrador Sea, it may generate a surface flood wave or a tsunami if the water mass is large enough and introduced in a short time. To our knowledge no previous calculations have been made to estimate the potential impact of a flood burst on the generation of solitary waves. Using analogies of tsunamis generated by submarine landslides and ocean earthquakes, the amplitude of a Lake Agassiz generated tsunami is estimated to have been at least 2 m. Directionality considerations, as well as the effect of the Coriolis Force in the Northern Hemisphere, suggest that the resulting tsunami probably traveled 50-100 km along the west coast of the Labrador Sea, south of Hudson Strait where the outburst entered the ocean, before being dissipated. The erosional and depositional affects of historic and prehistoric tsunamis are present in the geological record, and provide guidance in seeking evidence for the Lake Agassiz flood burst and subsequent tsunami. This record may be found along the western coast of the Labrador Sea as well as along the shores of Hudson Strait

Crafts and gear used for marine fishing along the Andhra Pradesh coast

Until the middle of nineteen sixties fishing for marine finfishes and shellfishes along the Andhra Pradesh coast used to be carried out employing indigenous non-mechanised crafts. Subsequently trawlers and later mechanised vessels operating gillnets came into use which resulted in the increased fish production. Use of outboard engine on indigenous crafts for reaching fishing grounds is a recent feature of near the coast fishing. The different kinds of non-mechanised and mechanised crafts and gear employed in the region are dealt with in this article

Comparison of Repeated Sprint Ability and Fatigue Index Among Male Handball Players with Respect to Different Playing Position

The intent of the present study was to compare repeated sprint ability and fatigue index among male handball players with respect to different playing position. I have selected thirty two (32) male handball players from Department of Physical Education and Sports Sciences, Annamalai university, Chidambram, Tamilnadu, India. These players were classified into four groups as backs (n = 12), wings (n = 7), pivots (n = 7) and goalkeepers (n = 6) respectively. These selected subjects, who practice handball regularly and take part in competition. The selected subjects mean age: 21.62 ± 1.90 years; weight: 64.59 ± 7.25 kg and height: 172.07 ± 7.25 cm. The volunteered subjects signed a separate consent form to participate in the study. The repeated sprint ability and fatigue index were selected as criterion variables. To evaluate the repeated sprint ability and fatigue index all subjects completed multiple sprint running protocols, which consisted of 7 × 30 m sprints repeated at 25 s intervals. The total sprint time was calculated by summation of all seven sprint time and fatigue index was calculated from sprint times using the following formulae: Fatigue = {(slowest sprint – fastest sprint) / fastest sprint} x 100. The collected data was analysed using one way Analysis of variance (ANOVA). When F ratio was found significant, Scheffe’s post hoc test was applied to know the difference between the four groups. The result of the study showed that total sprint time (F = 6.163, p = 0.002) and fatigue index (F = 4.577, p = 0.010) showed a significant difference among male handball players in different playing position. It denotes that total sprint time and fatigue index found to be best in wing players and poor in goalkeepers. It is concluded that lower total sprint time and fatigue index by repeated sprint ability is an important for wing players as they are the players who perform the most picks and require high levels of aerobic capacity to aid recovery after high-intensity bouts of activity. However, it also required for back court, pivot and goal keepers. It importance cannot be neglected since all the field players in the court gets equal chance for fast break and quick counterattacks. The role of the repeated sprint ability is greater and which determines the result of the match

Effect of High Intensity Interval Training on and Anaerobic Capacity and Fatigue Index of Male Handball Players

The purpose of this study is to find out the efficiency of high intensity interval training on anaerobic capacity and fatigue index of male handball players. To achieve the purpose thirty (30) male handball players were selected from Department of Physical Education and Sports Sciences, Annamalai University, Chidambaram, Tamilnadu, India. These subjects were tested on anaerobic capacity and fatigue index before and after eight weeks of high intensity interval training (HIIT). The mean maximal aerobic speed 4.21 m/s was used as a criterion velocity to set running paces for high-intensity interval training. Statistical technique used in the present study was ANCOVA for anaerobic capacity and fatigue index. The result of the study revealed that eight weeks of high intensity interval training resulted in 28.58% in anaerobic capacity (F(1,27) =28.54, p < 0.05) and fatigue index (F(1,27) =14.11, p < 0.05). It is concluded that high intensity interval training for eight weeks resulted in improvement of anaerobic capacity and fatigue index of male handball players

Diurnal Rhythms in Selected Physical Variables before and During Ramadan Fasting

The purpose of the present study was to assess diurnal variations in selected physical variables before and during Ramadan fasting. The physical variables (speed, speed endurance, agility and power) were documented around the clock at five 4-hourly intervals before Ramadan began and on the twenty-third day of Ramadan (daytime fasting). Ten healthy nonsmoking male handball players volunteers were included in the study after routine clinical and laboratory examinations. These subjects were selected from Department of Physical Education and Sports Sciences, Annamalai University. Their ages averaged 27 ± 1.9 years. Time series were analysed with repeated measures ANOVA which revealed that there was a statistically significant changes as a result of Ramadan fasting among experimental days and times on speed, speed endurance, agility and power. Experimental day and time interaction showed that during Ramadan, compared with control period, time related variations of speed, speed endurance, agility and power changed significantly. To evaluate rhythmicity, the single cosinor method was used. Cosinor analysis clearly shows the shift in acrophase obtained from the subjects before to the 23rd day of Ramadan fasting. Ramadan induces day time changes in speed, speed endurance, agility and power

Effect of Daytime Melatonin Administration on Tympanic Temperature Heart Rate and Endurance Capacity

The purpose of this study is to know the effect of pre-cooling strategy using 3mg of melatonin during daytime on tympanic temperature, heart rate and endurance capacity. Twenty four physically active and healthy males were randomly classified into two groups namely melatonin and placebo, each constitute of 12 players. The age, height and body mass were 21.13 ± 0.80 yr, 1.79 ± 0.5 m, 78.4 ± 5.1 kg, respectively. Tympanic temperature, heart rate and endurance capacity was selected as criterion variable. Single dose of Melatonin (3g) and placebo were supplemented to respective group around 10:00. ANCOVA was administered. The results of this study indicate that the 3 mg of melatonin significantly affected the tympanic temperature (F (1&21) = 12.68, p = 0.002) and heart rate (F (1&21) = 6.48, p = 0.019). However endurance capacity did not show any changes (F (1&21) = 2.308, p = 0.144). It is inferred from the results of the present study that 3mg of melatonin significantly affect the tympanic temperature and heart rate but failed to show any impact on endurance capacity
