Parent-teacher interviews: how to make the most of them

EXTENDED BODY:

Editor of parenting website Kiwi Families and former teacher turned parenting guru, Rochelle Gribble discusses how to get the most out of parent-teacher interviews and student-led conferences.
Here are some tips to help you maximise this short window of opportunity to find out what is going on for your child at school, and how to approach it, especially if things are going wrong.
Parents go in to these meeting with their own school ‘baggage’. Try to put it aside. Teaching and learning have changed since you were at school.
Have any questions written down, and say at the beginning of the meeting that you have some things you want to talk about.
The things you probably want to find out about are your child's learning, behaviour, and socialisation. Ask the teacher: How well are they participating? What can they do well? How are they relating to other children? What are the next steps for my child? What other support can we use?
Be an acronym-buster – if you don’t understand the words you’re hearing, ask for them to be explained.
If you don’t get through everything, or other issues occur to you later, follow up with the teacher by e-mail and possibly make another appointment.
If you think there is an issue with the teacher - you don’t rate them, or they and your child don’t get along, talk to the syndicate leader, dean or other ‘next-up’ teacher. If you think there might be a personality clash rather than bad behaviour from the child, ask the teacher for specific examples of issues so you can work out if there is more that needs to be done.
Student-led conferences – where the child attends the meeting - can have good and bad aspects. It can be good for children to hear about ‘next steps' they need to take to improve, but it may not be helpful for them to hear about how badly they are doing. You can ask the child to step out for part of the conversation, or make a time to phone or visit the teacher to talk about the hard stuff at another time. This will also give the teacher time to collect any relevant information.
Teachers are busy. Start by e-mailling to set up a suitable time to follow up.
If there is a big concern, don’t save it up for the parent-teacher meeting. Let the teacher know in advance that you have concerns, and perhaps make a separate time when this can be focused on.

From Egg to Dinner – Breeding Better Salmon
BODY:
Veronika Meduna visits a salmon hatchery to find out more about how salmon are bred and farmed, and about the family tree of each fish.
EXTENDED BODY:
By Veronika Meduna
In the wild, salmon spend most of their lives in the ocean and return to rivers to spawn, and then die.
The largest species in the Pacific salmon family, the King salmon or Chinook, is the only one farmed in New Zealand. It was introduced from northern California as a game fish in the late 19th century, but it wasn’t until the 1980s that the first salmon farms were set up in the Marlborough Sounds.
Farmed salmon now accounts for more than a fifths of the aquaculture industry in New Zealand, which also produces green-lipped mussels and oysters, with a combined export value of $252 million.
New Zealand King Salmon freshwater manager Jon Baileys says the company’s breeding programme is based on family trees and has established seven generations of King salmon over the past two decades, which includes more than 90 distinct families, selected for traits in breeding success and product quality.
All our brood stock are kept in freshwater for their entire life. The traits we select for are growth and age of maturation, so whether they mature at three or four years of age, and then the flesh quality traits, such as fat content in flesh and the colour of the flesh.

All breeding fish are tagged and genotyped against their parent generation to avoid any inbreeding, and the breeding stock is evaluated against their siblings that are kept in seawater pens.
“That means we select fish that perform well in seawater, which is where production fish are grown. We can select the best families in freshwater and then the best fish from within those families to not only produce the eggs for production but also the next generation of brood stock.”
At its hatchery just of Takaka, the clear and cold water of Te Waikoropupu Springs supplies a constant flow to the freshwater pens where breeding fish are kept. “The reason we use this water is its clarity, which is well known. It remains clear year round regardless of the weather and the season and for farming salmon that’s just excellent because the fish can see their food all the time.”
Another constant is the water temperature, which at 11.7 degrees Celsius is in the middle of the range for freshwater salmon farming.
Mature females are separated out into tanks where they are aneasthetised and killed before their eggs are removed. At the same time, another team collects milt from males, making sure to avoid any contact with water, which would activate the sperm.
Salmon stop feeding as they reach maturation and put all their energy into producing eggs and sperm. They develop a darker skin as their scales are absorbed and transformed into a thick mucus layer. In the wild, this would be the time when they travel upstream into rivers to spawn and need a tougher skin to negotiate obstacles.
The hatchery's incubation room is a biosecure area and staff have to wear protective gear and change footwear to prevent the introduction of any pathogens. Once the eggs have been fertilised, they are rinsed with water to harden the shell and kept for a month until the fish embryo’s eye is clearly visible.
From there, the salmon spend another year in freshwater, and the juvenile fish are then transported to sea pens to mature.
Earlier this year, the government announced a $5.2 million project to study the specific dietary requirements of King salmon.
Half of the money for the five-year project comes from the government through Seafood Innovations Ltd (SIL), a research partnership supported by the Ministry of Business, Innovation and Employment. The other half is being funded by commercial and research interests – New Zealand King Salmon, Danish feed producer BioMar, Nelson's Cawthron Institute and the Nelson Marlborough Institute of Technology.
Fish Health Manager for New Zealand King Salmon, Mark Preece, says the project's aim is to improve the efficiency of food use.
We are progressing towards this by firstly determining the digestibility of raw ingredients and if we find any indigestible ingredients, then removing them. Once that's done, we'll develop our 'best possible diet' and benchmark that against the commercially available diet. The primary reason for this work is that most science on diet development is carried out on Atlantic salmon. We farm Pacific salmon, so we need to know what's best for them.

He says no antibiotics or hormones are used in salmon feed, but the pigment Astaxanthin is added. "Astaxanthin is a nature-identical essential nutrient that happens to make the fish pink. It is an identical replica of the colorant found in krill and includes an antioxidant that enhances the salmon health and performance."

The big picture with Simon Morris
The comic book world is dominated by two companies – Marvel and DC. DC’s Superman and Batman films tend to be dark, ultra-serious and borderline Fascist. Marvel is far more on the side of the underdog. Even their superheroes are plagued with self-doubt.
Possibly the most subversive Marvel movie was provided by Hollywood iconoclast Shane Black. His Iron Man 3 not only found a new angle to Robert Downey Junior’s title character, but he came up with the genre’s most interesting villain - the too-bad-to-be-true Mandarin, played to the hilt by Sir Ben Kingsley.
But even the best comic-book films can’t escape the fact that they’re… comic book films. No matter how cunningly devised and well acted they are, they stand and fall on three little words: Bam! Splat! And Kapow!
But though we may roll our eyes at these technicolour mastodons, and cry out for something more nourishing, the trouble is that comic-book films, and their animated cousins, make grown-up films look a bit tame and old-fashioned.
Like Sir Ben Kingsley’s own new film, Learning to Drive - about a tightly-wound New York book critic, played by the always reliable Patricia Clarkson, who belatedly finds she needs to drive herself when her husband leaves her. Her instructor is a dignified Sikh refugee, played by Ben Kingsley.
The film is everything you want from a grownup film – that is, a film about adults, a little slight, maybe, but beautifully written and acted.
Later I talk with the equally dignified Sir Ben Kingsley, who’s rather more fun than I was expecting – particularly when the conversation turns to the Beatles, the Olsen Twins and dressing in drag.
But the big movie this week was the debut of Marvel Comics’ smallest super-hero, Ant-Man.

EXTENDED BODY:
Simon Morris looks at the new Marvel Comics movie, Ant-Man, starring Paul Rudd playing a reformed burglar.
Ant-Man starts with quite a few strikes against it. First of all, Ant-Man? Really? A hero as small as an ant is an unpromising hero to talk up, you’d think. But the biggest problem for me is I’ve seen so many of these films now. Ant-Man is simply one tight-fitting suit too far.
In fairness, my neighbours at the Ant-Man screening were three young chaps - average age about 11 - who had the time of their lives, whooping and hollering at every size-changing action stunt.
Unlike many Marvel movies, Ant-Man isn’t complicated by too many villains. Instead it throws in some father-daughter issues.
But once the action gets under way, Ant-Man is basically a traditional heist movie, with added trick photography. The stunts and the comedy were the attractions for my 11-year-old neighbours. The rest of us get the likable Paul Rudd and Michael Douglas, and the fact that micro-battles are frankly hilarious when the camera pulls out.
Ant-Man is entertaining enough, if you’re not good and sick of comic-book films now. My neighbours enjoyed every moment of it, and why shouldn’t they? It was made for them.
But after nearly ten years trapped in the comic-book store, I’m looking for the exit.

When Sir Ben Kingsley made his extraordinary film debut in, and as, Mahatma Gandhi - two Golden Globes, two Baftas and one Academy Award - everyone in Hollywood who knew anything predicted that it would be too hard an act to follow.

But of course nobody in Hollywood knows anything. Sir Ben's career has been as extensive as it's been astonishing in range - from Schindler's List to Sexy Beast, from House of Sand and Fog to Hugo, where he played French film pioneer Georges Melies. I have very fond memories of him upending expectations in Iron Man 3, blending horrific menace and knockabout comedy in one role.

This week, Sir Ben Kingsley returns in a sweet little film called Learning To Drive, playing a Sikh taxi-driver opposite old friend Patricia Clarkson.

From Egg to Dinner – Breeding Better Salmon
BODY:
Veronika Meduna visits a salmon hatchery to find out more about how salmon are bred and farmed, and about the family tree of each fish.
EXTENDED BODY:
By Veronika Meduna
In the wild, salmon spend most of their lives in the ocean and return to rivers to spawn, and then die.
The largest species in the Pacific salmon family, the King salmon or Chinook, is the only one farmed in New Zealand. It was introduced from northern California as a game fish in the late 19th century, but it wasn’t until the 1980s that the first salmon farms were set up in the Marlborough Sounds.
Farmed salmon now accounts for more than a fifths of the aquaculture industry in New Zealand, which also produces green-lipped mussels and oysters, with a combined export value of $252 million.
New Zealand King Salmon freshwater manager Jon Baileys says the company’s breeding programme is based on family trees and has established seven generations of King salmon over the past two decades, which includes more than 90 distinct families, selected for traits in breeding success and product quality.
All our brood stock are kept in freshwater for their entire life. The traits we select for are growth and age of maturation, so whether they mature at three or four years of age, and then the flesh quality traits, such as fat content in flesh and the colour of the flesh.

All breeding fish are tagged and genotyped against their parent generation to avoid any inbreeding, and the breeding stock is evaluated against their siblings that are kept in seawater pens.
“That means we select fish that perform well in seawater, which is where production fish are grown. We can select the best families in freshwater and then the best fish from within those families to not only produce the eggs for production but also the next generation of brood stock.”
At its hatchery just of Takaka, the clear and cold water of Te Waikoropupu Springs supplies a constant flow to the freshwater pens where breeding fish are kept. “The reason we use this water is its clarity, which is well known. It remains clear year round regardless of the weather and the season and for farming salmon that’s just excellent because the fish can see their food all the time.”
Another constant is the water temperature, which at 11.7 degrees Celsius is in the middle of the range for freshwater salmon farming.
Mature females are separated out into tanks where they are aneasthetised and killed before their eggs are removed. At the same time, another team collects milt from males, making sure to avoid any contact with water, which would activate the sperm.
Salmon stop feeding as they reach maturation and put all their energy into producing eggs and sperm. They develop a darker skin as their scales are absorbed and transformed into a thick mucus layer. In the wild, this would be the time when they travel upstream into rivers to spawn and need a tougher skin to negotiate obstacles.
The hatchery's incubation room is a biosecure area and staff have to wear protective gear and change footwear to prevent the introduction of any pathogens. Once the eggs have been fertilised, they are rinsed with water to harden the shell and kept for a month until the fish embryo’s eye is clearly visible.
From there, the salmon spend another year in freshwater, and the juvenile fish are then transported to sea pens to mature.
Earlier this year, the government announced a $5.2 million project to study the specific dietary requirements of King salmon.
Half of the money for the five-year project comes from the government through Seafood Innovations Ltd (SIL), a research partnership supported by the Ministry of Business, Innovation and Employment. The other half is being funded by commercial and research interests – New Zealand King Salmon, Danish feed producer BioMar, Nelson's Cawthron Institute and the Nelson Marlborough Institute of Technology.
Fish Health Manager for New Zealand King Salmon, Mark Preece, says the project's aim is to improve the efficiency of food use.
We are progressing towards this by firstly determining the digestibility of raw ingredients and if we find any indigestible ingredients, then removing them. Once that's done, we'll develop our 'best possible diet' and benchmark that against the commercially available diet. The primary reason for this work is that most science on diet development is carried out on Atlantic salmon. We farm Pacific salmon, so we need to know what's best for them.

He says no antibiotics or hormones are used in salmon feed, but the pigment Astaxanthin is added. "Astaxanthin is a nature-identical essential nutrient that happens to make the fish pink. It is an identical replica of the colorant found in krill and includes an antioxidant that enhances the salmon health and performance."

Sea Urchins and Their 'Landscape of Fear'
BODY:
Do sea urchins live in a 'landscape of fear' and is the mere presence of predatory crayfish and snapper enough to change their behaviour?
EXTENDED BODY:
By Alison Ballance
“Fear is causing them to be more cryptic. It’s a really cool result. Predators don’t actually have to be having a direct effect on the sea urchins to potentially limit how much kelp they graze.”
Arie Spyksma, Leigh Marine Laboratory

When wolves were re-introduced into Yellowstone National Park in the United States, the park’s vegetation began to rapidly change. And it wasn’t that the wolves were eating all the deer – it was that the mere presence of the wolves was causing the deer to spend more time hiding in the forest, and less time out in the open eating grass.
Ecologists call this the 'landscape of fear’, and University of Auckland PhD student Arie Spyksma wonders if the same thing could be happening closer to home – but with sea urchins instead of deer, and snapper and crayfish rather than wolves.
This time-lapse video was made by Arie Spyksma as part of his research. For the first 4 seconds you see a crowd of sea urchins behaving normally. Then, after a white perforated pot containing some crushed sea urchin is introduced, many urchins react to the smell by moving away from the pot. At the same time a number of fish come in to investigate the pot. Arie says the crushed sea urchin is a proxy for a sea urchin being eaten by a crayfish or snapper, and is a way of seeing how the urchins react to their predators. The metal poles and fluttering tape at the left and right of shot are the legs of the tripod holding the time-lapse camera.
Arie has been comparing the behaviour of sea urchins, or kina (Evechinus chloroticus) both inside and outside two marine reserves – the Leigh, or Cape Rodney to Okakari Point marine reserve, and Tawharanui marine reserve. In unprotected areas of the Hauraki Gulf ‘kina barrens’ are a common feature – over-fishing results in low numbers of popular species such as crayfish and snapper, both of which are key predators of sea urchins. As a result, the numbers of sea urchins builds up, leading to the over-grazing of the common kelp, Ecklonia radiata. What happens in a fully protected marine reserve once fishing is prohibited is that snapper and crayfish numbers recover, sea urchin numbers go down and at the same time the kelp also begins to recover.
“There’s a theory known as the trophic cascade theory,” says Arie. “When predator numbers are high they can effectively control herbivore numbers - so herbivores like the sea urchin – which keeps their numbers in check and means that they’re not over-grazing the kelp, and it keeps the ecosystem in a good balance. If those predators are removed then the herbivore populations will explode, they’ll over-graze and then you’re left with a reef that’s got no kelp on it, has got low coralline and turfing algaes, and isn’t as productive and can’t hold as many species.”
The main idea behind the trophic cascade theory is that it is direct interactions between the predators and their prey i.e. the predator eats the prey species and removes it. What Arie is investigating is a growing idea that the indirect effects of predators may be as, if not more, significant.
“By causing the urchin to fear for its life and stay hidden or cryptic, the urchins are not going to be out on the reef as much and therefore might not graze the kelp as much,” says Arie.

Arie has carried out his research both in the field and in the lab at the Leigh Marine Laboratory. To begin with he compared the size and behaviour of sea urchins inside and outside the marine reserves. He observed that the smaller population of urchins inside the marine reserve were more cryptic and spent much more of their time hiding, compared to those outside the reserve which spent much more time out in the open, even when they were quite little (just 40 mm in size).
However, this could have been either because they were hiding from greater numbers of predators in the marine reserve, or that there was simply more food in the reserve so they didn’t have to spend so much time looking for it but could rely on drift algae coming to them as they hid.
To tease those two possibilities apart Arie ran some experiments in the lab, exposing sea urchins to the smell of crushed sea urchins that he hoped would “mimic another sea urchin somewhere in the area being attacked.” He also created scenarios with and without lots of kelp being washed around the tank.
“Then for about three weeks I’d get up every four hours and go and see what the urchins were doing” says Arie. “So by the third week there was a very clear separation between the groups of urchins with and without predator cues. When predator cues [the crushed sea urchin] were present a much higher proportion of the sea urchins were cryptic on a daily basis, and this was regardless of whether there was food present or not present.”

So, Arie concludes, it seems that ‘fear’ of predators was shaping how urchins behaved in the lab, and subsequent work he has done back out in the field, filming how urchins react to different cues (crushed fish versus a crushed sea urchin, for example) certainly backs up this result. Our underwater world, then, really does seem to be a ‘landscape of fear.’

In this two-part story, Ruth Beran meets Maui Stuart who was recently diagnosed with sleep apnoea after an overnight sleep study at WellSleep, a sleep investigation centre based at Wellington's Bowen Hospital.
Jessie Bakker from the University of Otago, Wellington who worked at WellSleep explains what sleep apnoea is, how it is diagnosed, what happens during a sleep study, and demonstrates the gold standard treatment - a continuous positive airways pressure (CPAP) machine.

Jessie Bakker recently led a study analysing why some people in the community are less likely to continue with CPAP treatment. The first part of the study was based on a questionnaire of 127 patients living in the Greater Wellington area, and found that ethnicity did not independently predict compliance with CPAP after measures like socioeconomic deprivation and education were factored in.
The second part of the study involved three focus groups where eight New Zealand Europeans, five Maori and five Pacific patients, and while discussions did touch on culturally-specific aspects, all groups discussed common problems like financial barriers to CPAP use, feeling overwhelmed with the CPAP educational material, and the importance of role models.
Maui Stuart benefited from the discussion group, and has been changing his life ever since he was diagnosed with sleep apnoea. He has continued with CPAP treatment, has changed his diet, and is now doing regular exercise. He has lost over 25 kilograms so far, and his goal is to swim the Cook Strait.

North Island Brown Kiwi Genome
BODY:
The genome of the North Island brown kiwi has just been published by an international team of researchers
EXTENDED BODY:
By Alison Ballance
The North Island brown kiwi has just joined kea and rifleman in an exclusive club – birds that have had their entire genome sequenced.
There are 10,000 or so species of birds worldwide, and the genomes of just 50 of those have been worked out. That three New Zealand birds are amongst the 50 is testament to how unusual our avifauna is.
The work, 'Kiwi genome provides insights into evolution of a nocturnal lifestyle' has just been published in the journal Genome Biology by a team of German and Australian researchers. What they have found in the genes confirms that kiwi are pretty much colour blind, but are super-sniffers when it comes to smell.
This infrared video of a male North Island brown kiwi calling was recorded by Dr Isabel Castro and her team.
Conservation genomics researcher Dr Tammy Steeves at the University of Canterbury says that bird genomes are much smaller than mammal genomes, but that the kiwi genome is one of the largest bird genomes.
“On average bird genomes are about one billion base pairs,” says Dr Steeves. “And the kiwi genome is about one and half billion base pairs.” This compares to 3.2 billion base pairs in the human genome.

“Bird genomes are usually about a third of the size of the human genome, and that’s one of the things that makes them so fascinating,” says Dr Steeves.
“They’re very compact and they don’t have a lot of what we call repetitive elements or repeating DNA sequences, and they’re also highly conserved, so even when we look across very distantly related birds they have very, very similar genomes.”
There are five species of kiwi in New Zealand, and they belong to a group of flightless birds known as ratites, which includes the extinct moa as well as ostriches, emus, cassowaries and rheas.
Genetics and genomics researcher Professor Neil Gemmell, from the University of Otago, says the publication of the North Island brown kiwi genome is significant.
“It’s a pretty major achievement,” says Prof Gemmell. “Kiwi genomes are a little bit bigger than most bird genomes. It’s the first kiwi genome sequenced in its entirety, and I think it’ll be a really useful resource for future kiwi research in New Zealand.” He says it should also improve our understanding of how kiwi fit into the ratite group of birds.

he researchers of the North Island brown kiwi genome were particularly interested in investigating the genetic components of the bird’s unusual flightless, nocturnal behaviour, especially their olfactory receptor genes and their vision receptor genes.
“We know that kiwi have poor eyesight – they have some adaptations for nocturnal viewing but their sense is quite under-developed,” says kiwi ecologist Dr Isabel Castro from Massey University.
“But they have a fantastic sense of smell – they have a very big area of the brain that is devoted to the sense of smell. One of the things that you notice when you’re working with kiwi in the wild is that they use their scent of smell and their scent of touch for everything.”
A previous study had identified a number of olfactory receptor genes in brown kiwi, but this new research has added to that tally.
“What this new group is doing is a more advanced way of looking at it,” says Dr Castro.
“We already knew that kiwi had a lot of olfactory receptor genes, but [what the new study reveals is] that they might be more sensitive to more smells than we ever thought before.”

While brown kiwi had similar genes for black and white vision to other vertebrates, the researchers identified mutations in the blue and green vision receptor genes that rendered blue and green colour vision absent.
Still no answers for why kiwi lost flight
The German and Australian researchers estimate that kiwi adapted to a nocturnal lifestyle about 35 million years ago (30-38 million years), soon after the then-flighted birds flew to New Zealand.
While the team also investigated the genes involved in limb development, they weren’t able to draw any conclusions about when kiwi lost their wings.
The researchers suggest that competition with moa drove the smaller kiwi to a nocturnal life style, but Dr Castro says this seems unlikely. Rather than competition from much larger herbivorous moa, she suggests that competition from smaller insectivorous birds - and predation by avian predators such as falcons and eagles - probably drove the small ancestral kiwi to become active at night.
As far as on-the-ground conservation management of this threatened species goes, conservation genetics expert Dr Helen Taylor, from the University of Otago, says the sequencing of the brown kiwi genome doesn’t mean much immediately.
“But it does mean that we’re making progress towards being able to get large-scale genetic data sets for [all kiwi species] more easily and more cheaply. It will act as a guide for doing genotyping by sequencing across North Island brown kiwi and across other species of kiwi as well," she says.
"And the nice thing about those techniques is that it allows us to get really high resolution genetic data so we can make better decisions about what genetic diversity they have, what population structure there is and these kinds of things are very helpful for informing good conservation management.
“These are things we can address with current genetic tools... But what genomic tools mean is we can get at this data in a much more high resolution way and get much more accurate answers.”
Prof Gemmell says that, with the brown kiwi genome now sequenced, it should be easier to do the others.
"You’re not trying to assemble things from a blank slate... You’re working from a framework where you can actually take the sequences you generate form the other kiwi species and you align them against that matrix.”
More bird genomes on the way
The genomes of a number of New Zealand birds are being worked on at the moment – among them little spotted kiwi. This work is focusing on the transcriptome of the little spotted kiwi and is being led by Dr Kristina Ramstad at Victoria University of Wellington.
Prof Gemmell and Dr Steeves both expressed disappointment that no New Zealand-based researchers were involved in the work.
“It certainly doesn’t matter from the quality of the science,” says Dr Steeves. “The science is very good and it’s very exciting. And what I would like to see moving forward, particularly on the conservation front, is that we see the involvement of local expertise.”
She says when it comes to kiwi conservation management it is important to involve all the stakeholders, which includes the Department of Conservation and local iwi and communities.
A brief history of genome sequencing

The first genome to be sequenced, in 1976, was a small single-stranded RNA virus called Bacteriophage MS2. Its genome comprised just 3569 pairs.
The first animal to have its genome sequenced was the fruit fly Drosophila in 2000.
The human genome was sequenced in 2001.
In 2004, the red jungle fowl became the first egg-laying animal to have its genome sequenced.
The human genome has 3.2 billion bases. Compared to mammals, bird genomes are quite small. Dr Steeves says bird genomes average 100 billion base pairs, but the kiwi genome is quite a bit bigger, with 1.5 billion base pairs.
