the black cat logo , developed in 1957 by the founder mr . yasuomi ogura himself , has become the national symbol for transport in japan and will be all over the world . in the eighties yamato transport established networks in south - east asia , the u . s . a . and europe , which were further greatly expanded .
after the economic boom in the sixties and the recession in the seventies , yamato transport made the right and daring decision to free themselves from the contracts and convert their takkyubin delivery system into a door - to - door delivery network for individual clients and consumers . from this point on the company grew and introduced other services like home - moving and refrigerated transport .
today , yamato handles the most ambitious worldwide transport and moving challenges . with its innovative ta - q - bin and other advanced supply chain solutions that capitalize on ever - increasing urbanization , yamato stands at the forefront of service excellence and innovation . the advent of online shopping , ordering via smartphone , the need for time / temperature sensitive shipping solutions , along with just - in - time production , has yamato poised for a new era of growth . at the company’s core lies a great resolve for sustainability through corporate responsibility to its employees and every market segment served .
yamato began its operation in japan in 1919 as a short haul transportation company . as yamato approaches its 100 - year anniversary , it has grown to approximately 200 , 000 employees and over 7 , 000 business facilities worldwide . by applying time tested know - how , yamato provides total supply chain and logistical solutions by maximizing transport speed while still maintaining its high quality of service . the company logo , a cat carrying a kitten in her mouth ( symbolizing the care given every shipment ) is the best known logo on the island nation , as familiar to the japanese as the coca - cola logo in the united states .
those among you who know yamato transport ' s caring cat logo , will be relieved to see it in europe . those who don ' t will soon find out that it is a convenient ticket into this complex continent . and moreover it will be your successful guide into the japanese market . this is why we have proudly introduced our “sales assistance service” , enabling you to use our specific know - how on the main economic markets of this world . our complete logistic concept allows you to either put the entire distribution in our hands or choose any service you require from warehousing to door - to - door distribution .
probably the best reason for anyone who wish to work for yamato is for the sake of practicing japanese language not culture per se . whether you wish or not , you will have to learn so much about japanese culture and how to convey business japanese in order to advance your career within the company . if you are not money hungry and have genuine interest in japanese language , then go for it .

your trust is our top concern , so companies can ' t alter or remove reviews .
please always think about what you can do to serve customer better and to make a new employee work comfortably . please give the employees a training including yourself as to how they could build a happy and lively workplace . that is one of the essential elements for prosperity of business .
any person can work even if there is no academic background . almost every year salary will go up .
there are many harassment with only japanese boss . it is a raise of three dollars in ten years .
salary is not competitive unless you work in the commercial ( logi ) department and do so well . if you go to a small local branch , you only get to employ japanese all day long . english is useless .
they are not considering the wellness of each employee and branch . they dont provide any solution to serious situations some branches are facing . we dont need any wicked ideas . we only need practical ones .
the staff members are generally great to work with . the management does not know how to utilize them .
the management is very expat oriented , and they cannot treat their staff very well . they just let good people leave the firm .
good health benefits and vacation time . yearly bonus even in the worst of times . flexible when time is needed off . the employees are friendly and work well together in most of the departments .
employees are not appreciated . managers are more interested in saving themselves then helping the employees . there is no training . instead of dealing with bad employees , they are either ignored or transferred ( if japanese ) to become the problem of someone else .
management needs to take employees opinions to heart and to really listen to what they have to say with an open mind . but i do not see that happening . too much infighting between managers .
basically good co - workers but it ' s too japan - oriented .
it ' s a part of japan ' s biggest logistic company and the tie with japan side is tighter than you imagine . people working there were basically nice but you have to follow the japanese style management . salary was fair for the industry but the big difference between local and expats seemed to be too much which didn ' t make any sense . benefits were above par , i think .
the company was still targeting japanese market in u . s . which was ridiculous . too closed for non - japanese . i didn ' t see good sign for the company growth . most of the higher management were expats from japan and they tend to follow the rule and style of their parent company in japan .
some employees were talented and motivated but they were all wasted under the wrong management .
dead end career , japanese style of business close mindedness , no innovation . ridiculous guidelines made by incompetent management , rules such as cell phone to work , or water bottle in non - designated area ( yes they have an area for you to keep your water bottles ) results in a warning or sometimes fire on the spot . almost impossible to climb up the ranks ( if you ' re not japanese speaking , good luck ) , no holiday compensations , poor working conditions ( for warehouse expediters ) , summer work is unbearable ( due to heat , and hardly any fans provided ) , strong show of favoritism , low pay , mediocre benefits , etc .
management , get your heads out of the sand , and start opening your ears to what your employees say . provide better working condition for the warehouse employees ( whom is the foundation to the entire business operation . ) higher pay to employees , most company employees are making little over minimum wage .
relatively low stress work environment , decent benefits after probationary period , relatively easy job .
almost 100 % of the employees in the branch are japanese . rotation management from japan rarely possess any english speaking ability . communication between employees and management is poor . a very japanese working culture is maintained despite the company being in america , which often makes communication , understanding of expectations , and work - life balance very difficult for non - japanese employees . the employees are stuck in an environment that promotes maintaining the small business that they have because that ' s what works in japan , rather than finding new ways to improve and expand .
the company needs to adapt its practices better to the countries that it operates in and hire management native to the countries it operates in .
this will replace the current featured review for targeted profile . are you sure you want to replace it ?


berkeley models , inc. was an american company that manufactured model-airplane kits that pioneered such firsts as the nation 's first gas model plane kit , and which became one of the industry 's leading companies .

founded in the brooklyn borough of new york city , new york , and later based in west hempstead , new york , it lasted from 1933 to 1962 .

its founder , bill effinger , was elected to the academy of model aeronautics hall of fame in 1986 .

i sort of went ‘all in’ on an auction for a berkeley interstate cadet this week . in 30 hours , we will see if i won it or not . before this auction , i had no idea this kit existed in the berkeley line . do you know where i can find a complete listing of the 35 inch scale ff berkeley kits ?
bob : thanks so much for your berkeley blog . it really touched a nerve when i first read it . in fact , your blog launched a renewed interest in me for revisiting the 35 inch span free flight civilian aircraft line from berkeley .

i’m just getting back into the hobby after a long absence and i’d never heard of berkeley before . i’ve been cruising through the balsa kits on ebay and mostly been checking out guillows , comet and sterling . i also found a nice selection of berkeley . you’re not kidding when you say they command a premium price .

i have collected berkeley kits for about fifteen years . what wonderful kits they are . i bought a berkeley b - 25 on e - bay in december 2009 . i paid $ 325 . 00 and thought that was a reasonable price . later i paid about the same price for a b - 26 invader , also on e - bay .
both testing and training auc values had high discriminatory power for im were excellent for 255 models , good for 72 models , fair for 35 models , poor for 8 , and failed for 0 . for the em auc values were excellent for 511 models , good for 156 models , fair for 60 models , poor for 10 , and failed for 3 . when averaged across decades auc test values were excellent for 22 , good for eight , and fair for seven species . for auc train values were excellent for 28 , good for eight , and fair for one species . the internal and external validations suggest that the im and em models are similarly parameterized and well calibrated ( s2 table ) . both of the transferability indices generally provide similar results and suggest that the models are highly transferable ( s2 table ) . the rrs statistic found that many models had values close to 0 indicating strong agreement between the im and em , however there were a number of models that suffered from over - and under - prediction ( s2 table ) . while under - prediction was more common than over - prediction , the magnitude of over - prediction was larger ( s2 table ) . the oi statistic revealed that for many models there was high - predicted overlap between the im and em models , although there were some exceptions ( s2 table ) . while most of the metrics suggest that the models are accurate , well fit , and transferable , there are some em that either over or under - predicted the im , as well as some em that had low overlap with the im , suggesting that these discrepancies arise either as an artifact of modeling , or that some other factor potentially related to life history characteristics affects model prediction and transferability .
the original kit was designed by paul delgatto for berkeley ' s in 1955 . we have recreated the classic model by laser cutting all of the original die - cut parts .

enms can become erratic when transferring projections in space and time [ 6 , 10 ] . while this study used internal and external validations to ensure that models were well parameterized , accurate , and transferable , some models suffered from over - or under - prediction . over - prediction could emerge as an artifact of thresholding , or as a by - product of model parameterization . if a particular threshold was always more lenient ( lower ) than other thresholding approaches than ranges would always tend towards over - prediction , however this was not the case . if the models were over - parameterized then the expectation is that the transferred models would under - predict the range , while the converse is true for under - parameterized models . in some studies , maxent has been known to remove too many variables , resulting in over - predicted range sizes due to under - fit models [ 16 ] . here the high degree of over - prediction for some species suggests under - fitting , although the fit statistics indicate that the models are well parameterized .
bob , came accross your website today ( saturday 4 - 23 - 2011 ) i can relate to the old berkeley’s , as i’m in my late sixty’s . 1st berkeley was the culver v . over the years , i have collected the berkeley kits of which i now have close to 50 or so . along with others ( sterling , sig , comet , cleveland , etc . ) you are correct that the value has gone skyhigh on these kits . i guess when the lord takes me , i will build them up stairs . take care , steve douglas , charlotte , nc
the first two train lines arrived in the city the 1870s , said phil gale , mechanical engineer and treasurer for the berkeley historical society . the berkeley branch line , which later became southern pacific ( sp ) , ran from what is now emeryville to downtown berkeley , and was later extended to vine street . the other early line was a union pacific train that ran from 3 rd street to delaware street . shortly after , the first street railroad was built on telegraph avenue . in the following years additional lines were added elsewhere and companies began to electrify their lines around the turn of the century .

all of these contests related to either gliders or rubber models , because mr . hurst felt that the gasoline powered model was dangerous , and he resisted it .
i had two of the carved fuselage control line models , a p - 51 and a p - 38 , both christmas gifts , but never got up the courage to try flying them even though i was by then pretty good with something like a ringmaster . i built a whole series of the 1 / 2a free flight models and tried to fly most of them without really knowing what i was doing . a few years later when i was a bit more grown up and a whole lot more skilled at model building , the quality of the entire berkeley line suffered from the use of really bad balsa as a cost control measure and before anyone really noticed , they were gone . these days you won’t find the name berkeley on a hobby shop shelf anywhere , and most modelers have never heard of them . there is one balsa wood model airplane kit now on the market that can be traced back to the berkeley lines…do any of you know what it is ?

“i’ve been really interested in the local history and the amazing public transportation system that berkeley had , ” he said . “a lot of it has been replaced by more modern systems , but not necessarily better systems . ”
in the early 60s i built a lot of ff scale models . somehow in the workshop there had always been a kit , berkeley b - 17 flying fortress , which challenged my imagination . i remember carving the fuselage for nearly a year , listening to tv and movies about the plane . i read every book and magazine , and went to airshows to enjoy the sight and rumble .
one day the school principal asked me to show him my models . he asked me to bring the models over and we flew them in the school auditorium . he was quite impressed , and told me that i could fly my models there any time . all i had to do was just ask the janitor to let me in . however , that didn’t work so great because the janitor always seemed to want to hide when i came around , as he was always in a hurry to do something else .

a primary assumption of environmental niche models ( enms ) is that models are both accurate and transferable across geography or time ; however , recent work has shown that models may be accurate but not highly transferable . while some of this is due to modeling technique , individual species ecologies may also underlie this phenomenon . life history traits certainly influence the accuracy of predictive enms , but their impact on model transferability is less understood . this study investigated how life history traits influence the predictive accuracy and transferability of enms using historically calibrated models for birds . in this study i used historical occurrence and climate data ( 1950 - 1990s ) to build models for a sample of birds , and then projected them forward to the ‘future’ ( 1960 - 1990s ) . the models were then validated against models generated from occurrence data at that ‘future’ time . internal and external validation metrics , as well as metrics assessing transferability , and generalized linear models were used to identify life history traits that were significant predictors of accuracy and transferability . this study found that the predictive ability of enms differs with regard to life history characteristics such as range , migration , and habitat , and that the rarity versus commonness of a species affects the predicted stability and overlap and hence the transferability of projected models . projected enms with both high accuracy and transferability scores , still sometimes suffered from over - or under - predicted species ranges . life history traits certainly influenced the accuracy of predictive enms for birds , but while aspects of geographic range impact model transferability , the mechanisms underlying this are less understood .

converse to results from mcpherson and jetz [ 5 ] , this study found that the models for temperate migrants tended to have lower accuracy than those for neotropical migrants or resident species . different studies have come to different conclusions regarding how well models capture the distributions of migrant versus resident birds [ 63 , 72 ] , suggesting that this may vary across geographies and assemblages .
although it has been suggested that collinear predictors do not affect maxent model building , but instead impact model interpretation [ 73 , 74 ] , the inclusion of variables that are collinear can lead to over - fit models and potentially to the elimination of biologically relevant variables [ 40 ] . these models are expected to under - predict the range [ 51 ] , and indeed , this accords with findings from braunisch [ 47 ] in which complex models ( retaining highly collinear predictor variables ) performed better than simpler models ( retaining independent variables ) , despite potential over - fit and under - prediction . although we did observe examples of under - prediction in this study , it was of small magnitude , suggesting that collinearity is not driving the results .

for birds , some of the life history traits that have been examined with regard to enm performance include range size , conservation status , migratory behavior , rarity , endemism , body mass ( size ) , habitat structure , and wetland affinity ( reviewed in mcpherson and jetz [ 5 ] ) . of these traits , range size , migratory behavior , and wetland affinity have detectable impacts on model performance for south african bird species . narrow ranged species models performed better than those for common species , non - migrant species models were better than those for migrants , models for endemics outperformed models for non - endemics , non - wetland species models outperformed wetland species models [ 5 ] . however , the characteristics that contribute to a successful interpolative model ( e . g . a model built and projected within the same climatic and geographic environment ) , may not be the same as those that make for a successful extrapolative model ( e . g . a model built using one climatic and geographic environment and then projected to a different climatic or geographic environment ) [ 6 ] . therefore , transferability as it relates to life - history characteristics should ideally be evaluated explicitly .

this series invites an array of grammar types useful both as learning devices and as research tools . the freedom to break away from latin and greek grammar models , traditionally required , in particular of indo - european historical languages , is respected and even urged when appropriate . on the other hand , the valuable genetic study of language should remain a sought - after , well - developed endeavor , and should not be lost to the present and future world of learning . accordingly , the berkeley models of grammars series seeks forward - looking , theoretically sophisticated methodologies which are at the same time relatively exhaustive or complete grammars of a given language at any period of its existence .

since there are recent studies investigating model variation with regards to geographic transferability [ 37 ] and temporal transferability [ 11 ] and both have found strong support for high transferability of maxent models , i used maxent 3 . 2e [ 38 , 39 ] to build models and then project them into the “future” . enms using matched decadal occurrence records and climate data were generated for each decade , then projected forward in time , such that enms generated using 1950s occurrence points and 1950s climate , were projected to 1960s , 1970s , 1980s , and 1990s climates ( fig 1 ) . interpolative models ( im ) , are developed using occurrence data from a particular decade in conjunction with historical climate data from the same decade , and are expected to be good representations of the species’ distribution [ 14 ] . the extrapolative models ( em ) , which are the interpolative models projected onto a ‘future’ climate are more prone to error because they are built using climate data that differs from the climate to which they are projected [ 16 ] .
interesting to hear the name of berkeley kits . in the 60’s my uncle was briefly partners in a hobby shop . when it closed he gave my dad a berkeley models “b26 invader” model kit with 87 1 / 2 inch wingspan . its huge ! the kit was half built . a guy contacted wanting to “borrow” it . he let the guy take the plans with him only to find out he left a false phone number ! my uncle did not know the guy either so the plans were gone . i still have the kit and someday hope to figure out the proper locations for the fuselage bulkheads . the wings are built . to date i haven’t found anyone who has ever heard of the kit let alone has a plans set .

to gauge model transferability i examine the magnitude of over - or under - prediction and assess the overlap between modeled ranges . this approach assumes that the im better represents the true distribution than does the em [ 16 , 68 ] . external model evaluation was performed using two auc - based transferability indices to gauge the accuracy of the extrapolative models . both ti h ( ti h = auc ( em ) / auc ( im ) ) , developed by heikkinen et al . [ 37 ] and ti w ( ti w = ( 1 - ( auc diff ( em ) ) ) / ( 1 - ( auc diff ( im ) ) ) developed here , are simple ratios in which values less than one indicate that the interpolative models are providing more accurate predictions than the extrapolative models . values close to one are indicate equivalent accuracy of interpolative and extrapolative models . the second index , ti w differs from ti h by incorporating the internal evaluation into the ratio . i also use metrics to quantify mismatch between the interpolative models ( im ) and the extrapolative models ( em ) . the metrics used here are from [ 69 ] and include the relative range size ( rrs ) and the overlap index ( oi ) . they are intended to provide insight into the performance of the transferred extrapolative models ( em ) relative to the interpolative models ( im ) . the relative range size ( rrs ) ( if im < em rrs = em / im - 1 , else rrs = - 1 ( im / em - 1 ) is a measure of the over - or under - prediction of suitable area of the em relative to the im . a positive number means that the em over - predicts the range , a negative value means it under - predicts the range , and a value close to 0 indicates model similarity [ 16 ] . the overlap index ( oi ) ( oi = ( o / im ) ) quantifies agreement between the predicted and projected species range . oi records the amount of congruence between the im and em models . it is a simple ratio that quantifies the overlap between the im and em models with respect to the im . values range from zero to one . a value close to one indicates that the em performs well in predicting the species range . a low value indicates little agreement between the models .
the performance of enms built using historical climate and occurrence data varied in their ability to predict “future” species distributions . in this study models were projected to highly similar analogous environments , under the expectation that they should transfer well [ 61 ] . the testing auc scores for the models were overall quite high , and the models were well calibrated with only a slight tendency toward over - parameterization ( which is less problematic than under - parameterization [ 52 ] ) . although the transferability scores were generally high , the transferability of the models varied . while the glms did not find any of the life history traits to be significant predictors of transferability as measured by ti h or ti w , the oi statistic suggests that commonality versus rarity of species across their distributional ranges may play an important role in the predictive ability of extrapolated models . in this study , this was the only life history character that significantly predicted overlap . in contrast , the wilcoxon test suggests that there are statistically significant differences in transferability for narrow versus widespread species , but not for common versus rare species .

i probably built half a dozen kindling wood models using lepages glue , which has to be the worst excuse for glue man ever invented , and covered them with wax paper . you know , it really is hard to get wax paper to stick to wood using lepages glue . somehow , i was able to get it done . some of my models actually flew eight or ten feet , especially if i threw them kind of hard .

for range , widespread versus narrow species distributions but not the commonness or rarity of the species impacted the model accuracy , with narrowly distributed species having higher model accuracy than widespread species ( fig 2 ) . to determine if this finding reflects an artifact of modeling or an effect of life history trait , auc scores for models for narrowly distributed species were re - evaluated with a reduced background extent and then compared to models with the full background extent . the two sets of models were found to be statistically significantly different ( auc test : t = 5 . 4379 , p - value = 0 . 000 ) which suggests that these differences arose as an artifact of modeling .

many studies examining the impact of life history traits have recovered a pattern whereby models for narrow ranging , endemic species have higher model accuracy than those for widespread species as assessed by auc scores [ 5 , 10 , 63 , 64 ] . however , for species occupying a restricted range relative to the extent of the background area modeled , auc scores can be elevated as an artifact of modeling due to sampling prevalence and sample size [ 57 ] , and pseudo - absences [ 14 , 65 , 66 ] . by explicitly evaluating the effect of background extent on auc scores for these species , the artifacts that arise from modeling should become evident [ 66 ] . to untangle artifacts of modeling from effects of life history traits , i generated a second set of models for narrow ranging endemics using a reduced background extent ( extent restricted to states where a cbc circle recorded a presence ) and then compared the auc scores from the two models sets using t - tests to assess if background extent impacted estimates of model performance . since sampling size and the number of background points were held constant , and therefore neither sampling prevalence or sample size should be affecting differences among the sets of models , a significant difference between the models ( full extent versus reduced extent ) suggests that pseudo - absence selection influences auc scores . if the models do not differ statistically , the higher auc scores recovered for narrow ranged species may reflect a true effect of the underlying species ecology .

models for both neotropical migrants and residents had high levels of model accuracy , while models for temperate migrants had markedly reduced accuracy ( fig 2 ) . among the six major habitat categories included in these analyses , model accuracy for wetland species exhibited a large amount of variation , although the mean auc was high ( fig 2 ) . the wilcoxon test found support for significant differences in accuracy for both range components ( e . g . widespread vs narrow , common vs rare ) ( table 4 ) .

berkeley’s population more than tripled in the first ten years of the 20 th century , gale said . train construction boomed , accommodating the new residents — and then “the whole thing came crashing down in 1913 , ” due to major financial and legal problems throughout the system , gale said . streetcars and some trains ran until the 1940s and 1950s , until they were gradually replaced by buses .
do any of you old timers remember a berkeley sailboat model with a 36″ preformed hull that was a yawl named the “tiki” as i recall . i wonder if these kits ever show up on ebay . if so , what sort of price might these go for . i built one of these back in the late fifties and i think the price might have been around $ 30 at that time .

i also built a flew several of the berkeley control liners ; a sr . puddle jumper was about the first . later , a p - 6e very neat model . also my first r / c was a henry struct “bootstrap” , then a “rc sea cat” . i know i bought a scale b - 25 but never built it and i do not know where it got lost . i still have an in the box , control line stunt . 60 size “snark” .
a total of 555 models were constructed ( 15 models for each species ) . as previous analyses have demonstrated equivalent model performance with full versus subsets of environmental variables [ 16 ] , and i had no a priori information by which to select variables across the modeled set of species [ 40 ] , i used 19 bioclimatic variables for model building ( s1 table ) . however , there are two schools of thought regarding variable selection when using maxent [ 41 ] , one suggests including all reasonable predictor variables [ 38 , 42 , 43 ] , the other suggests removing collinear variables [ 41 ] . in maxent , allowing more predictor variables allows more complex model fitting , and by default maxent determines which predictors to use based on the number of occurrences in the dataset [ 44 ] . maxent uses weighting for variable selection , as well as an l1 - regularization procedure that penalizes models in which predictor variables with little or no contribution are included [ 41 , 45 ] , thus it is generally thought to be less sensitive to model over - fitting than other methods [ 42 , 43 ] ( but see [ 46 ] ) . furthermore , if the relationship among variables is not constant over time , the inclusion of multiple collinear predictors has been found to produce better performance and fit as compared to reduced variable models [ 47 ] . however , if variables are highly collinear , ecologically relevant predictors may be excluded if a collinear variable better explains the response variable [ 40 , 48 ] . from a purely statistical standpoint , reducing collinear variables reduces the potential for mis - identification of critical variables [ 40 ] . to better understand the potential impact of collinearity among the predictor variables in the maxent models , and the constancy of variable relationships across decades , i calculated variance inflation factors ( vif ) using the r package usdm [ 49 ] .
i had to carve the fuselage thin enough to see light through , to keep weight low . i used 4 golden bee motors which performed so well for decades . the nose art was great , took first in cl scale at the nats . hard to describe how much fun and education i derived from that one berkeley b - 17 flying fortress kit . today it would have been rc , rc in the early 60s could not always be adapted too easily for some airplanes . .
by this time the summer work was paying better , and i was able to buy a dennymite motor , which was one of the best ones built at the time . i built several different models around that dennymite motor , and i placed in quite a few contests , and won one ( free flight , i believe ) . in retrospect , the gas models were more of a challenge , but i learned more from building rubber models because they built easily , and because i was able to try out so many different thoughts . i learned quickly that a triangle fuselage was stiffer than a rectangular one , that diagonal verticals were stiffer than straight ones . regardless of what charles hampson grant said in his center of lateral area theories , i found that if i put the wing up front on a high pylon , it stayed right side up . i learned that if you wanted a model to catch and stay in a thermal , that you had to cut down the rudder area to the bare minimum . i learned that an all weather airplane , one that you could fly in the rain , won more hardware than a fair weather ship that was a tremendous flyer .
there are berkeley kits around , if you know where to look . check out model airplane swap meets , poke around in the stacks of dusty old kits you might be fortunate enough to run into , and you could be lucky enough to spot one of the old red , black and white kit boxes . they are considered collector’s items , and the few that have survived the years in excellent condition command serious prices . i have never considered myself a collector , but i am very much interested in old time balsa wood airplane kits like the berkeley line that are no longer pristine or even complete but preserved well enough that a determined , skilled aeromodeller can actually build an airplane from them . for me , building a model airplane i remember from my youth , using all the skills i have acquired over the years to do a far better job than i could ever have dreamed of in those days , and then actually flying it using state - of - the - art micro radio control and electric power is a nostalgia trip to write home about .
i found the caption page yesterday , finally . this is the page i had trouble finding again . i remember that easy built had a couple of kits that they touted as r / c models . i suppose the pt - 19 was one of them ? i did find a tigerkitten kit on ebay yesterday and its now on its way to me . i always liked the lines of that model .
johnston is expecting his initial audience to be largely made up of collectors and historians , but he hopes to eventually tear kids away from their digital distractions and reintroduce them to the classic pastime . eventually , he hopes to collaborate with current transit agencies to make models of contemporary trains . he made himself a model of a bart car , which he keeps in his pocket as a lucky charm when he takes the train to work .
later , while i was at wright field , anderson finished the tool and sampled it . they then sent me sample parts . i was able to get a machine shop in dayton to machine up the parts for the first die cast . 59 . a few weeks later i was discharged from service . i took my newly made motor back to los angeles . at that time i didn’t have any models or any place to build one .

in order to test the temporal transferability of enms , i build models using historical data from fifty years of field surveys ( 1950 to 1999 ) in combination with historical climate data and project them to the “future” ( in this study “future” refers to 1960 to 1999 ) . the projected models were validated through comparison with survey data from the time period to which they have been projected . model validation using serial temporal sampling is becoming more common ( for recent examples [ 19 , 25 ] ) , providing an independent means for assessing model accuracy [ 24 ] . since differences between modeling approaches are less impactful and insightful than other factors when evaluating transferability [ 6 , 7 , 11 ] , rather than focusing on the transferability of different modeling techniques ( see [ 11 , 37 ] for recent reviews ) , i use a single model type with high extrapolative ability . using historical data in this manner provides a more robust framework for evaluating temporal transferability than consensus modeling approaches since consensus approaches emphasis precision rather than accuracy [ 6 ] .
the house we had lived in was repossessed . fortunately , my father had owned a vacant lot and was able to buy a milk shed for $ 15 . 00 . we moved the milk shed onto the vacant lot . shortly after this the economy started easing up a little bit . no matter how tight things were , though , i was able to come up with 75 cents or $ 1 . 00 a month to send away for model building supplies , and i kept building models after school all of this period .
the decreased transferability found in this study could have potentially arisen due to some of the specific characteristics of the data utilized in these analyses . for some species , the range limits of the winter range extend beyond the borders of the continental united states , and these areas were not used in constructing enms . projecting to highly novel climates , can lead to decreased transferability if the entire geographic range is not sampled [ 85 ] . this arises because some combinations of climatic variables are not included during model building , which can result in models that do not capture the upper and / or lower ends of the environmental envelope [ 85 ] . this could underlie some of the instances of under - prediction found here , but does not explain over - prediction . furthermore , the climates in these analyses are analogous across all decades . there is no evidence to suggest that novel climatic combinations existed during the 50 years ( as assessed by the absence of clamping and with the mess statistic ) . as such , models should be both highly accurate and temporally transferable within the continental united states .
here i examine the relationship between life history characteristics and model accuracy and transferability for a subset of north american birds . i use historical occurrence records in combination with historical climate data to forecast to the current climate and to validate the models . using historical data to assess model accuracy and behavior is a highly informative approach to model validation , and is the only direct method to assess temporal transferability [ 11 , 15 , 19 , 24 ] . i quantify model accuracy , parameterization , and transferability , and then use generalized linear models to relate differences in these measures to differences in life history characteristics among species . this is done over a relatively short time period ( 50 years ) in a region where climate is roughly analogous , thus the expectation is that transferability should be very high unless they are impacted by either artifacts of modeling or life history characteristics . this study focused on species with relatively steady ranges over the past fifty years rather than those with documented range shifts . by doing so it becomes more straightforward to disentangle artifacts of modeling from the effects of life history traits on predictive accuracy and transferability .
the commonness or rarity of the species ( range ) was a significant predictor for oi but not rss ( table 3 , fig 3 ) . the oi was higher for rare birds indicating better agreement between the im and em models than for common birds , interestingly , glms did not find any of the life history characteristics examined here to be significant predictors of model transferability as measured by ti h or ti w metrics ( table 3 ) , although the wilcoxon test did recover significant support for differences in transferability for narrow versus widespread species ( table 4 ) .
