The effect of ambient oxygen on the thermal performance of a cockroach, Nauphoeta cinerea [RESEARCH ARTICLE]

Emily J. Lombardi, Candice L. Bywater, and Craig R. White

The Oxygen and Capacity-Limited Thermal Tolerance (OCLTT) hypothesis proposes that the thermal tolerance of an animal is shaped by its capacity to deliver oxygen in relation to oxygen demand. Studies testing this hypothesis have largely focused on measuring short-term performance responses in animals under acute exposure to critical thermal maximums. The OCLTT hypothesis, however, emphasises the importance of sustained animal performance over acute tolerance. The present study tested the effect of chronic hypoxia and hyperoxia during development on medium to long-term performance indicators at temperatures spanning the optimal temperature for growth in the speckled cockroach, Nauphoeta cinerea. In contrast to the predictions of the OCLTT hypothesis, development under hypoxia did not significantly reduce growth rate or running performance, and development under hyperoxia did not significantly increase growth rate or running performance. The effect of developmental temperature and oxygen on tracheal morphology and metabolic rate were also not consistent with OCLTT predictions, suggesting that oxygen delivery capacity is not the primary driver shaping thermal tolerance in this species. Collectively, these findings suggest that the OCLTT hypothesis does not explain moderate-to-long-term thermal performance in Nauphoeta cinerea, which raises further questions about the generality of the hypothesis.

Is APOE {varepsilon}4 associated with cognitive performance in early MS?

Objective

To assess the impact of APOE polymorphisms on cognitive performance in patients newly diagnosed with clinically isolated syndrome (CIS) or relapsing-remitting MS (RRMS).

Methods

This multicenter cohort study included 552 untreated patients recently diagnosed with CIS or RRMS according to the 2005 revised McDonald criteria. The single nucleotide polymorphisms rs429358 (4) and rs7412 (2) of the APOE haplotype were assessed by allelic discrimination assays. Cognitive performance was evaluated using the 3-second paced auditory serial addition test and the Multiple Sclerosis Inventory Cognition (MUSIC). Sum scores were calculated to approximate the overall cognitive performance and memory-centered cognitive functions. The impact of the APOE carrier status on cognitive performance was assessed using multiple linear regression models, also including demographic, clinical, MRI, and lifestyle factors.

Results

APOE 4 homozygosity was associated with lower overall cognitive performance, whereas no relevant association was observed for APOE 4 heterozygosity or APOE 2 carrier status. Furthermore, higher disability levels, MRI lesion load, and depressive symptoms were associated with lower cognitive performance. Patients consuming alcohol had higher test scores than patients not consuming alcohol. Female sex, lower disability, and alcohol consumption were associated with better performance in the memory-centered subtests of MUSIC, whereas no relevant association was observed for APOE carrier status.

Conclusion

Along with parameters of a higher disease burden, APOE 4 homozygosity was identified as a potential predictor of cognitive performance in this large cohort of patients with CIS and early RRMS.

Establishing and quantifying the causal linkage between drainage and earthworks performance for Highways England

Transportation infrastructure owners manage an array of different asset types such as bridges, road pavements, earthworks and drainage. Currently, most organization management procedures are siloed by asset type; however, there are important interactions between these asset groups that need to be managed in a cross-asset way. Although these interactions are known, there is little or no quantification of these interactions. For the first time, this paper quantifies that 74% of Highways England's earthwork failures are a result of drainage-related problems, either the lack of drainage infrastructure or the poor performance of it. The analysis undertaken is an important first step not only in moving towards more connected asset management planning for earthworks and drainage, but to also provide guidance for other owners of earthwork infrastructure assets to improve their strategic asset management procedures.

Analytical Performance Specifications for Lipoprotein(a), Apolipoprotein B-100, and Apolipoprotein A-I Using the Biological Variation Model in the EuBIVAS Population

Abstract
Background
With increased interest in lipoprotein(a) (Lp[a]) concentration as a target for risk reduction and growing clinical evidence of its impact on cardiovascular disease (CVD) risk, rigorous analytical performance specifications (APS) and accuracy targets for Lp(a) are required. We investigated the biological variation (BV) of Lp(a), and 2 other major biomarkers of CVD, apolipoprotein A-I (apoA-I) and apolipoprotein B-100 (apoB), in the European Biological Variation Study population.
Method
Serum samples were drawn from 91 healthy individuals for 10 consecutive weeks at 6 European laboratories and analyzed in duplicate on a Roche Cobas 8000 c702. Outlier, homogeneity, and trend analysis were performed, followed by CV-ANOVA to determine BV estimates and their 95% CIs. These estimates were used to calculate APS and reference change values. For Lp(a), BV estimates were determined on normalized concentration quintiles.
Results
Within-subject BV estimates were significantly different between sexes for Lp(a) and between women aged <50 and >50 years for apoA-I and apoB. Lp(a) APS was constant across concentration quintiles and, overall, lower than APS based on currently published data, whereas results were similar for apoA-I and apoB.
Conclusion
Using a fully Biological Variation Data Critical Appraisal Checklist (BIVAC)–compliant protocol, our study data confirm BV estimates of Lp(a) listed in the European Federation of Clinical Chemistry and Laboratory Medicine database and reinforce concerns expressed in recent articles regarding the suitability of older APS recommendations for Lp(a) measurements. Given the heterogeneity of Lp(a), more BIVAC-compliant studies on large numbers of individuals of different ethnic groups would be desirable.

New Federal Government CIO is Key to Improving Government Performance


The appointment of new federal chief information officer Steven VanRoekel comes at a challenging time for President Barack Obama. The national economy continues to be weak. Congress plans to cut trillions from the federal budget. And in the time leading up to the 2012 election, American voters remain cynical about the ability of the government to address important policy problems in an effective manner.

In an era of deficit reduction and public cynicism, the tasks facing federal officials are to determine how to do more with less and persuade voters the government can become smarter and more effective. There are going to be fewer dollars for virtually every federal program so it is important to figure how ways to innovate and perform more efficiently.

Former CIO Vivek Kundra sought to do this through encouraging agencies to move software applications to the cloud, consolidating federal data centers, improving transparency, and improving the information technology procurement process. It is important to continue this progress even as agencies are forced to downsize their operations.

As shown in the private sector, government administrators should use technology to cut costs, improve worker productivity, and streamline operations. This is not just a matter of using technology in more innovative ways, but changing the operations and culture of the public sector. Public officials must improve its data mining activities to identify fraud and abuse in Medicare, Medicaid, the Defense Department, and other domestic programs.

New software gives managers better tools to evaluate how money is being spent and whether it is fulfilling intended goals. If it is not, programs need to be modified or eliminated. The most important weapon in Mr. VanRoekel’s arsenal may be the scalpel as he goes through the federal government’s $80 billion IT budget.

Better schools or different students? Immigration reform and school performance in Arizona


Donald Trump has made waves during this year’s election cycle by taking a hard line on illegal immigration. This, however, builds on years of heated debate among policymakers. It is also an enduring hot-button issue in Arizona, which has passed several immigration laws over the years.  In 2010, the passage of SB 1070 brought national attention to this debate.  Deemed the strictest immigration law to date, SB 1070 sought to achieve “attrition [of illegal immigrants] through enforcement” by requiring law enforcement to detain any person whom they believed to be residing in the country illegally. Although SB 1070’s effects on individuals and families have been well documented, little is known about its impact on students and schools. To this end, we sought to estimate the relationship between the passage of SB 1070 and school-level student achievement.

We anticipated that anti-immigration policies would primarily affect children from the families of undocumented immigrants. Such effects could be observed in different ways. For instance, the emotional and psychological distress of these children could result in a decline in average test scores at the school-level. On the other hand, students might have left the country or the state under the threat of being deported in which case school-level test scores would rise (since these students often perform below their peers). To this end, we considered three scenarios: 

  1. Immigrant children remain in the state but experience higher levels of stress.  As a result, average school-level test scores will drop while Hispanic enrollment remains the same.
  2. Children of undocumented immigrants leave the state, which results in a drop in Hispanic enrollment accompanied by an increase in school-level test scores.
  3. Or, the first two scenarios occur simultaneously and we do not observe any change in test scores since the two effects would cancel each other, but note a slight decrease in Hispanic enrollment.

In order to see which of these hypothetical scenarios is supported by the data, we first estimated the relationship between the passage of SB 1070 and average school-level reading test scores. We then attempted to unpack the mechanism through which such an effect might have taken place. To this end, we used publicly available data on school-level achievement and enrollment collected by the Arizona Department of Education (ADE). Given the targeted nature of the policy and the demographics of immigrants in Arizona, the majority of whom are of Hispanic or Mexican descent, we focused on schools that traditionally enroll large proportions of Hispanic students. We identified schools with high (more than 75 percent) shares of Hispanic students as those whose average achievement and student composition are most likely to be affected by immigration reform. We contrasted changes in school-level achievement and enrollment in those schools with schools that enroll less than 25 percent Hispanic students, as these schools are less likely to experience any changes as a result of tightening immigration laws.

Figures 1 and 2 show trends in the average percentage of students passing the state reading test and average Hispanic enrollment at these schools between 2006-2007 and 2011-2012.           

Figure 1. Average Percent of Students Passing AIMS Reading

 

Figure 2. Average Hispanic Student Enrollment

Clearly, the rate of growth in school-level reading scores was much higher for high Hispanic schools after the passage of SB 1070 in 2010 (Figure 1). At the same time, there was a significant decrease in Hispanic enrollment in these schools (Figure 2). Thus, it appears the second scenario is likely driving the patterns we observe.

The data also suggest that the trends for high Hispanic and low Hispanic schools started diverging before the passage of SB 1070 - after the 2007-2008 school year.  This happens to be the year that Arizona passed an even more restrictive, though less controversial, immigration law – the Legal Arizona Workers Act (LAWA). LAWA required Arizona business owners to verify the legal status of their employees using E-Verify, an online tool managed by the federal government. Although LAWA used a different mechanism, similar to SB 1070 it sought to achieve the attrition of undocumented immigrants from the state. 

We then would anticipate both laws to have similar effects on school-level achievement and Hispanic enrollment. Indeed, we estimated that LAWA likely led to an average increase of roughly 4 percent of students passing the state reading test at high Hispanic schools. This was accompanied by an average loss of 38 Hispanic students per school. Because the passage of SB 1070 was preceded by the passage LAWA as well as a language policy that would have affected treatment schools, disentangling the effects of these two policies is not straightforward. However, based on our analysis, we estimate that SB 1070 is associated with an average increase of between 1.5 percent and 4.5 percent of students passing the state reading test at the school-level accompanied by an average loss of between 14 and 40 Hispanic students. 

Despite the fact that we cannot pin down the exact magnitude of SB 1070’s effect on school-level achievement, our analysis shows that when Arizona passed restrictive immigration laws in 2008 and 2010, it looked as if the state’s lowest performing schools were improving rapidly. This, however, likely had more to do with the changing composition of schools as an indirect though anticipated effect of immigration policies than with policies aimed at improving student achievement. 

Despite this, the Arizona Department of Education took credit for these gains. Similarly, Arizona was recently recognized as one of the nation’s leaders in growth on the National Assessment of Educational Progress (NAEP) over the last ten years. Although wrongly attributing these gains may seem harmless at first glance, it is important to remember that Arizona is viewed by many as a model for controversial education reforms like school choice and high-stakes accountability. It is easy to imagine how policymakers might look at increasing test scores in Arizona and wrongly attribute them to these kinds of reforms. That’s not to say that these policies don’t have merit. However, if other states adopt education policy reforms under the assumption that they worked in Arizona, then they might find that these policies fail to deliver.

Employment in June appears to rebound after disappointing performance in May


June’s jobs gains, released this morning, show that 287,000 new jobs were added in June, an impressive rebound after only 11,000 new jobs were added in May (revised down from from 38,000 at the time of the release).

This year’s monthly job gains and losses can indicate how the economy is doing once they are corrected to account for the pattern we already expect in a process called seasonal adjustment. The approach for this seasonal adjustment that is presently used by the Bureau of Labor Statistics (BLS) puts very heavy weight on the current and last two years of data in assessing what are the typical patterns for each month.

In my paper “Unseasonal Seasonals?” I argue that a longer window should be used to estimate seasonal effects. I found that using a different seasonal filter, known as the 3x9 filter, produces better results and more accurate forecasts by emphasizing more years of data. The 3x9 filter spreads weight over the most recent six years in estimating seasonal patterns, which makes them more stable over time than in the current BLS seasonal adjustment method.

I calculate the month-over-month change in total nonfarm payrolls, seasonally adjusted by the 3x9 filter, for the most recent month. The corresponding data as published by the BLS are shown for comparison purposes. According to the alternative seasonal adjustment, the economy added 286,000 jobs in June (column Wright SA), almost identical to the official BLS total of 287,000 (column BLS Official).

Data updates released today for prior months also reveal some differences between my figure and the official jobs gains from prior months. The official BLS numbers for May were revised down from 38,000 new jobs to a dismal 11,000. My alternative adjustment shows that the economy actually lost 6,000 jobs in May, down from 17,000 jobs gained at the time of the release. [i] The discrepancies between the two series are explained in my paper.

In addition to seasonal effects, abnormal weather can also affect month-to-month fluctuations in job growth. In my paper “Weather-Adjusting Economic Data” I and my coauthor Michael Boldin implement a statistical methodology for adjusting employment data for the effects of deviations in weather from seasonal norms. This is distinct from seasonal adjustment, which only controls for the normal variation in weather across the year. We use several indicators of weather, including temperature and snowfall.

We calculate that weather in June brought up the total by 25,000 jobs (column Weather Effect), but this should be considered a transient effect. Our weather-adjusted total, therefore, is 262,000 jobs added for June (column Boldin-Wright SWA). This is not surprising, given that weather in June was in line with seasonal norms.

It’s good to see the jobs numbers rebounding this month. The May number was somewhat affected by the Verizon strike. Also, it is important to remember that pure sampling error in any one month’s data is large, and that could explain part of the weak employment report for May. Averaging over the last three months, employment is expanding by about 150,000 jobs per month—a healthy pace, although a bit of a step down from last year.

a. Applies a longer window estimate of seasonal effects (see Wright 2013). The June 2015 to May 2016 values in this column have been corrected to remove a coding error that affected the previously reported values.

b. Includes seasonal and weather adjustments, where seasonal adjustments are estimated using the BLS window specifications (see Boldin & Wright 2015). The incremental weather effect in the last column is the BLS official number less the SWA number.


[i] Note that, due to a small coding error, my alternative seasonal adjustment for May, at the time of the release, should have been 17,000 new jobs, not -4,000, as was reported in my previous post. In addition to the underlying data revisions, and correcting for this error, the revised alternative seasonal adjustment for May is -6,000 jobs added (second row of column Wright SA).

Performance measures prove elusive for metro global trade initiatives

For the past five years as part of their economic development strategies, 28 U.S. metro areas have been developing global trade and investment plans. These metro areas have devoted substantial energy and resources to this process, motivated by the conviction that global engagement will have a significant impact on their economies. But things often change once plans are released: The conviction that fuels the planning process doesn’t necessarily translate into the resources required to put these plans into action.

Creating database of past performance to be ready for another shot at Olympics: Ashwini Ponnappa

Indian shuttlers Ashwini Ponnappa and N Sikki Reddy have finally got some time to pause and reflect due to the COVID-19 pandemic and they are making the most of it by creating a database to analyse their past performances while waiting for another shot at Olympic qualification. The coronavirus outbreak has left over 1.2 lakh people dead and infected nearly 2 million globally, and brought all sports activities, including badminton, to a halt after countries imposed lockdowns. Ashwini and Sikki are doubles specialists and endured an underwhelming season last year. The time at hand has given them a chace to analyse the past performances.

"We don't have any one to sit and do analysis for us, so now that we have time, I'm doing some analysis of our performance. I am jotting down points, about areas where I can improve. I started with my matches and then other players on tour," Ashwini, who represented India at the London and Rio Olympic Games, told PTI. "You can always watch and analyse and understand the patterns but it is different when you see things on paper. It is more concrete. So trying to set up a complete database. My brother will help me out. He made an app for me in the past." Ashwini and Sikki fell at the first hurdle 13 times in 20 tournaments last year, and exited from the second round thrice.

Ashwini also picked up a calf injury during the Syed Modi International but the duo was still confident of qualifying by performing well in the remaining Olympic qualifiers. But with Badminton World Federation (BWF) cancelling all tournaments due to the coronavirus pandemic, their fate remains uncertain. "The problem is we don't know the new BWF rules regarding the qualification. There is one year left now, you can't take a two year old performance to select for Olympics, it has to be present performance, so we have to wait," said Sikki. "In badminton, there is a ranking cut off, so how will they accommodate the cancelled qualifiers, how will they count the ranking points, everything is too messed up now," she added. Sikki and Ashwini had reached the finals at Hyderabad Open Super 100 and Maldives International Challenge, last year.

The Indian pair is ranked 28th and will need to be inside top 16 on April 29, 2021 -- the new Olympic cut off date. Ashwini said: "Me and Sikki were confident of doing well in the 4-5 tournaments left but now no one knows what would be the criteria of Olympic qualification and BWF can't really say anything with things changing every moment." They are using the coronavirus-forced break to learn cooking, besides doing some wall practice and exercises for physical fitness. Talking about the effects of the lockdown on mental health, Sikki said: "We have been travelling a lot all these years and now for a month, we are at home, it is fine. But what if it is for 2-3 months, then it will get tough to stay away from the game.

"So it is important to stay motivated for once the lockdown is lifted because you will in a comfortable zone in the break and then all of a sudden you will need to push yourself." Ashwini added: "...now that Olympics have been postponed, nothing is certain and it is tough, you have to be really strong." The economic fallout of the coronavirus outbreak has hit sports hard and Ashwini said badminton too will be affected. "It will hit in terms of sponsors, in terms of tournaments being conducted because countries need sponsors to host events, and after this, I'm not sure what the economic status of many countries would be. "The way things are, it is will be tough to host tournaments, it will not be easy for countries to have tournaments with many big companies shut and struggling to survive," she signed off.

Affordable art, Sufi performance and Bohri food at 3-day carnival


The art display at the debut edition of the festival

This weekend, if you step into the heritage precinct of the Great Eastern Mills compound in Byculla, you’ll get to feast your eyes on oil and watercolour paintings by 50 artists from across India. The showcase is part of the second edition of Art 35, a three-day carnival that celebrates affordable art. “Though we had a basic festival last year, I have taken it to a bigger scale this year by curating carpet displays, fashion apparel, jewellery and food stalls; paper and origami workshops for children and music performances too,” shares Charu Tewari, CEO of Ficus Fine Living, that’s presenting the festival.


Mooralala Marwada

The performance line-up includes an afternoon of Sufi renditions by Mooralala Marwada, a well-known folk singer from the Janana village in Kutch district of Gujarat. The artiste, who sings in the Kaafi form of music, will regale the audience with poetry of Kabir, Mirabai and Ravidas. Other must-catch acts include a Dastangoi storytelling session with Ankit Chadha and a stand-up comedy show titled Oye... Stand Up by Ankita Shrivastav and Mohit Sharma. The latter will also perform a solo act of Toba Tek Singh. The play based on Saadat Hasan Manto’s famous short story set in the aftermath of Partition will see the actor don 19 characters in 60 minutes.

The fest also offers a range of workshops — from one on digital photography by Himanshuu Chandrakant Sheth to tarot card reading by Ruchi Shah, finger painting, fabric painting, mural painting, collage making as well as cupcake decoration with fondants and frostings. Each workshop is curated for specific age groups, including two-year-olds.

These include gourmet lunchboxes for `500 whipped up by Savor, a subscription service launched by the folks behind The Secret Supper Project along with probiotic European fermented milk drink, Kefir, by Moina Oberoi, who runs the city’s first Kefir delivery service.

Irrfan Khan: An actor who charmed us all with his performances and persona

Irrfan Khan found success even in the harshest of times. The greatest stories are born out of sheer and scarring rejections and that's what Khan had to go through during his early years in the Hindi film industry. I'm reminded of an interview when he spoke about crying profusely on Raghubir Yadav's shoulders after Nana Patekar was given the role he was playing in Mira Nair's Salaam Bombay. But he knew he wanted a life and career in front of the camera.

Another great thing about success is that it never discriminates. Khan's was an unconventional aura yet very charming. He hailed from Jaipur, stayed at Tonk Road and had dreams of making it in Bollywood. The nation saw him for the first time in the immensely successful serial, Chanakya, and his eyes were so gripping and powerful, the viewers couldn't help but be hooked by his persona. He was here to stay.

His early years in Hindi films may have been unsensational but never once anyone doubted his tenacity as an artist. Even in smaller roles like Kasoor and Footpath, you could see the sincerity and earnestness with which he approached these characters. There was something special about his emotions and gravitas that with the same amount of expressions, he could be both chilling and comical. On one hand, we had a film like Gunaah, where he played an inebriated and innocuous police officer, and on the other hand was a film like Hindi Medium, where he made the audiences laugh and even cry.

He won the National Award for Paan Singh Tomar, a film that was driven by rust and robustness, and so was his performance as the eponymous character. It was only after this that he began to get roles that were not only exciting but also very exhilarating, for him and us, both. In The Lunchbox, he played Saajan, an ageing and ordinary man who falls in love with a woman he has never met, thanks to her delicious food that accidentally lands at his office desk. It was a restrained, real, and rousing performance that will always stay as delicious and fresh as the food he consumed.

Another crackling performance was in Shoojit Sircar's Piku, where he was pretty much stuck between a clumsy father and his cantankerous daughter. His deadpan demeanour always works in favour of the films he's a part of, and Piku was one of them. Call it the magic of the narrative or his own Midas touch that even if a single muscle doesn't move on his face, we know exactly how and what he's feeling. And that's precisely what he aspired for, to be a great artist. He never craved fame.

He once said, "Wanting fame is a disease and one day, I want to be free from this disease." Today, by God's will, he has been set free from all his pain and suffering as he departs, leaving behind tons of memories and superlative films and performances. Rest in peace, Irrfan Khan, until we meet again!

Kartik Aaryan claims Love Aaj Kal is 'best performance of my career yet'

Actor Kartik Aaryan said playing two characters in one movie would seem scary, but if the transition from Veer to Raghu in "Love Aaj Kal" was smooth he credits the film's director Imtiaz Ali for it. The actor feels Ali brings out great performances from actors in his movies.

Kartik took to Instagram and shared a still from "Love Aaj Kal", and also a picture of himself along with Ali. Alongside the image he wrote: "When you first dream of being in films, you act in front of the mirror and nail it every time, and the world of movies seems magical.?Then you get a movie. You see the camera and are unnerved. It's bigger than the suitcase you brought to Mumbai. The bright lights seem to be scolding you for not landing on a one inch tape mark and wasting everyones time."

"The first few years become about trying not to look nervous.?Then you get an Imtiaz Ali movie. The moment he narrates the story, you are pulled into a dream. I don't even remember seeing the camera on his set, he‘d always be standing wherever I looked after cut. He was never at the monitor, he was by my side. The lights on Imtiaz Ali's set help you find those tape marks," he added.

Kartik claimed he never experienced the kind of love and appreciation he got for his performance in "Love Aaj Kal". "And that too from some of my favourite filmmakers and people I most respect in the industry. How ironic that the making of this film felt most effortless. It would scare me to think of doing two characters in one movie. And here, I didn't even realise how smoothly I was being transitioned between #Veer and #Raghu," he wrote.

"For an actor, there is no better environment than being In front of that mirror. Imtiaz Ali takes you there. This is the reason why so many great actors' greatest performances have been in Imtiaz Ali films," Kartik added.

The actor then praised Ali and called him a "magician". "Imtiaz Ali director nahi hain, jadugar hain (Imtiaz Ali is not a director but a magician)! Thank you sir for giving me the best performance of my career yet. @imtiazaliofficial #LoveAajKal."

"Love Aaj Kal" co-starring Sara Ali Khan released on Valentine's Day this year. It traced love stories of two different eras -- the first is set in the late 1980s-early nineties, and unfolds between Raghu and Leena. The other love story, set in the present time, happens between Veer and Zoe.

The film is a retelling of Ali's own film of 2009 that starred Deepika Padukone and Saif Ali Khan, and was a hit. "Love Aaj Kal" 2020 fared below expectation at the box-office and was also critically panned.
