Errors in juvenile copepod growth rate estimates are widespread: problems with the Moult Rate method

first_imgThe ‘Moult Rate’ (MR) method has been used widely to derive stage-specific growth rates in juvenile copepods. It is the most common field-based method. Unfortunately, the equation underlying the method is wrong and, consequently, large errors in juvenile growth rate estimates are widespread. The equation derives growth from the mean weight of 2 consecutive stages (i and i + 1) and the duration of stage i. The weight change and the period to which this change is attributed are, therefore, offset. We explore this potential source of error in the MR method critically. Errors arise as a result of 2 primary factors: (1) unequal durations of successive stages and (2) unequal rates of growth of successive stages. The method of deriving the mean weight (arithmetic or geometric) also has an impact and is examined. Using a steady-state assumption, a range of scenarios and the errors that arise are examined. The literature is then reviewed and the size of errors resulting from MR method application in both field and laboratory situations is estimated. Our results suggest that the MR method can lead to large errors in growth estimation in any stage, but some stages are particularly prone. Errors for the C5 stage are often large because the following stage (the adult) does not moult, and has a different rate of body weight increase. For the same reason, errors are also great where the following stage is not actively moulting (e.g. when diapausing). In these circumstances, published work has commonly greatly underestimated growth. For example, MR growth ranges from 11 to 47% of the value derived correctly for this stage, gi_corr (calculated assuming the non-moulting stage does not grow). In late stages that are followed by actively moulting stages, the MR method has commonly given values in excess of 150% of gi_corr, but underestimation also occurs, with values <90% of gi_corr. We propose new methods and equations that overcome these problems. These equations are written with and without within-stage mortality included. The equations are relatively insensitive to mortality rates within the range found in the field, but only provided that the stage duration is not determined from moult rate. Stage duration estimates obtained from measuring moulting rates of field-collected animals are very sensitive to mortality rates of the animals prior to capture, and field mortality rates are often high enough to produce dramatic over-estimation of stage duration.last_img read more

Rick Williams, commander of Navy Region Hawaii and Naval Surface Group Middle Pacific, welcomed both ships to Hawaii, noting the advanced capabilities they bring to the Middle Pacific Fleet.USS Preble arrived at JBPHH as a replacement for the guided-missile frigate Reuben James (FFG 57), which was decommissioned July 18, 2013, and will serve as a MIDPAC surface combatant to reinforce maritime operations in the region.Cmdr. Robert T. Bryans, commanding officer of USS Preble, said he looked forward to bringing USS Preble’s advanced capabilities to the region and being a part of the MIDPAC team.As a new addition to MIDPAC, Sonar Technician Surface 2nd Class Chan Wakefield said the crew aboard USS Preble aims to answer the operational demands of the region, as well as take advantage of the rare opportunity of being homeported in Hawaii.Currently the most technologically advanced ship within the Ballistics Missile Defense (BMD) program, USS John Paul Jones will operate as a rotational BMD deployer, and testing ship, as part of a long-range U.S. commitment to the security and stability of the Indo-Asia-Pacific region.The move also allowed the guided-missile cruiser USS Lake Erie (CG 70) to proceed to San Diego for a scheduled, extended docking ship repair availability(EDSRA).Cmdr. Andrew Thomson, commanding officer of USS John Paul Jones, said his crew has proven that they are ready to assume the role as the Navy’s Integrated Air and Missile Defense test ship. In the coming years, the ship is expected to test newer and more advanced systems that will be used to defend the nation and allied forces overseas, Thomson said.USS Lake Erie is scheduled to replace USS John Paul Jones as a rotational BMD deployer out of San Diego once the EDSRA is complete.[mappress]Press Release, August 18, 2014; Image: US Navycenter_img August 18, 2014 Back to overview,Home naval-today USS Preble, USS John Paul Jones Arrive to New Homeport The U.S. Middle Pacific Naval Fleet received two new additions as the guided-missile destroyers USS Preble (DDG 88) and USS John Paul Jones (DDG 53) arrived to their new homeport of Joint Base Pearl Harbor-Hickam (JBPHH) August 14 and 15 from San Diego.

OUSU criticised for “irrelevant” discussion

first_imgOUSU council is facing criticism for an “irrelevant” discussion of policies that are due to expire this term.OUSU council annually evaluate every policy that is coming to the end of its fourth year. The policies, which are put forward by the Common Rooms and OUSU executives, are contained in the Student Union’s booklet of what OUSU believe.The policies range from extending library opening hours to campaigning against the use of sweatshop labour in University products.Students have been critical of this process. Jim O’Connell, Univ’s OUSU representative, has questioned the importance of the policy booklet itself, commenting, “I think there’s a danger of many students seeing this kind of long-winded process as being irrelevant to their needs, especially when issues under discussion include condemnation of the Armenian Genocide, which happened nearly a century ago.”He added, “It’s these kinds of motions that lead to the perception that OUSU wastes time and isn’t focused on the needs of students and common rooms.”Lewis Iwu has rebuffed these arguments. He said, “You might think that Policy Lapse is unimportant, but the motions contained in this booklet were each considered and debated in Council by your predecessors; MCR Reps, JCR Reps, OUSU Exec members and delegates. I’d hope that in a few years time, people take the time to review the debates we have in Council today and I hope you take some time considering the policies in this booklet.”Magdalen JCR president Laurence Mills also stressed the need to consider the application of OUSU policy to lives of regular students.He said, “Whilst we only go through this process once a year, I think that there are definitely some issues that we will be debating that a lot of students won’t think are relevant, and so it is important that we reassess whether or not we are focusing on the important aspects of student life that we can be making progress on.”One of the most controversial policies to discuss is OUSU’s pro-choice stance. Matthew Brown, the President of Oxford’s Pro-Life society has found it “strange” to “take such a definitive position” when the student union represents many individuals”.He added, “Note OUSU also refers to its pro-choice position as a ‘campaign’ which I believe to be unhelpful language. Their position is to ‘campaign’, in the affirmative, rather than to support all students.”Defending this position, Both O’Connell and Mills argued that OUSU’s pro-choice stance is vital to maintain. O’Connell said, “OUSU needs to be pro-choice because it has a direct and hugely important effect on welfare, because people confronted with that kind of situation need the best possible information and advice.”last_img read more

SMC students visit areas of campus featured in book of ghost stories

first_imgThirteen years after the publication of “Quiet Hours,” a collection of ghost stories taking place in various locations across Saint Mary’s campus, the Student Activities Board (SAB) held a tour Thursday for students to hear the book’s different stories in the buildings where they were reported to have occurred. SAB member Sinead Hickey said “Quiet Hours” was published in 2002 and written by Saint Mary’s alumnae Shelly Houser, Veronica Kessenich and Kristen Matha. While they were students, they interviewed hundreds of staff, faculty and local residents to put together a collection of stories of different sightings and happenings that transpired on campus. “All the stories are about occurrences which happened on our campus,” Hickey said. “This book is not only fun, but it also gives us a little insight into the history and identity of our school.”Hickey said the entertainment committee of SAB planned this tour as their main Halloween event.“This is a fun opportunity for students on campus because it is an option for a non-drinking Halloween event. You can have fun without a drink,” Hickey said. “It is a fun way to learn about the ghosts on campus and campus history. “Part of the Saint Mary’s identity is the ghosts present on campus.” The tour started in the south lounge of Regina Hall, Hickey said. Participating students received a map, which showed three of the dorms on campus — Regina Hall, Le Mans Hall and Holy Cross Hall — where members of SAB were stationed. Students then went to the three locations and SAB members read the corresponding stories in “Quiet Hours” that took place in each specific hall.In Regina Hall, students heard stories about pianos that played without anyone touching them, doors found inexplicably opened when they were originally locked and mysteriously rippling water in the pool that used to be in the building’s courtyard. Afterwards, students proceeded to Holy Cross Hall. This dorm was the first building of the College and was previously Saint Mary’s Academy. The book tells stories about a mysterious sighting of a young nun and a large dog in front of the building during a time when only a single, older nun wore a habit, and no nuns owned a dog. The book also notes occurrences of noises being heard in the bathrooms — especially those on the third floor — that sounded like people brushing their teeth or showering when no one was actually there.Sophomore Mackenzie Griffin, who participated in the tour, said she believes the stories.“I definitely think the ghosts stories on campus are real,” Griffin said. “I haven’t experienced anything, but there is a lot going on in the bathrooms in Holy Cross. You’ll hear people walk in and do their nightly routines, but there’s nobody there.”The last stop on the tour was Le Mans Hall, where students heard the stories of people from building services finding a child’s hand print on a window, security staff feeling a cold chill in the un-airconditioned Stapleton Lounge and a student seeing a man in Queen’s Court — reportedly one of the most haunted hallways in the building — run past her and through a wall during her nightly rounds as a Resident Assistant.

How managers can get better results by asking better questions

first_img 3SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr A manager’s ability to bring out the best in their direct reports is hugely affected by whether they engage them in conversations about what they, the manager, can do to help their direct report perform at their best. The usefulness of these conversations depends, in large part, upon the quality of questions the manager asks, because:When you ask people better questions, you get better answers, and therefore, the information you need to get better results from them.In this article, you will find a list of questions that will lead to productive conversations yielding valuable engagement and productivity-enhancing information from each employee.You will only use a few questions in any one conversation, given the depth of information each one can potentially provide.Questions 1-7 are a great way to start the process off, especially with new hires. Because the questions are about past managers and past employers, they require less candor and courage than answering questions about their current employer and current manager, i.e. you. Because of that, you can get incredibly useful information on how to bring out the best in them in a non-threatening, non-intrusive way. continue reading »last_img read more
