I triestini fanno le clanfe meglio dei friulani, lo dimostrerebbe uno studio apparso su “The new Bazovica journal of medicine”

Oggi pubblichiamo questo importantissimo studio di Aldo Rogna el Pescador apparso su “The new Bazovica journal of medicine”, rivista scientifica dall’impact factor decisamente vicino a quello del Monon Behavior, se non de più. Xe de dir, che scientificamente sto studio ghe dà straze a quel dela clanfa, poco de far.

Furlans and Triestins are different in performing clanfa: a longitudinal randomized trial
Aldo Rogna el Pescador, M.D., Ph.D.


In recent years researches disclosed a remarkable endemism of the provinc of Triest, i.e. the clanfa tuff. However, reasons why this particular monon behaviour involves only Triestin patoco adult male has not been well defined.
In a fifteen days longitudinal randomized clinical trial, ten participant were enroled, divided into two groups (five Furlans and five Triestins). At baseline, biometric characteristics of participant were recorded and during the trial, according to a cultural / enogastronomical / educational protocol, they were trained in clanfa
tuff and the level of the schizz in each clanfa session has been collected. The statistical analysis was conducted by R software.
The group of Triestins always achieved better (p<0.001) performances with respect to Furlans. No biometric characteristics of the participants appeared to be a valid predictor of the schizz (height p = 0.96, weight p = 0.49, body mass index p = 0.27).
Perfomance curves of the Triestins were also discussed.
Triestins are better clanfa tuffers than Furlans, but not for biometric reasons. The true reasons why this is so, it remains a mistèr, and further neuroscientific and socioeconomic investigations are needed.

In a remarkable series of papers [Manna 2009, Manna et al. 2009] professor D. Manna and collaborators focused attention onto an obscure endemism of the provinc of Triest, the so called clanfa tuff. Authors were able to demonstrate both edonistic and sexual motivations presents in this particular and pericolous tuff, usually well performed by male triestins at Barcola Beach – LittleRats. We recall that the primary endpoint of the clanfa is to schizz more higher than possible, and only as a consequence the male is able to attract the attention of the ciaping sun mule, distirated in the surroundings of the beach.
Recently, other two peculiar details which can cast new lights into the deep nature of the phenomenon have been disclosed. Firstly, the historical etymology of the tuff have been related to a maggiordom of the archduke Ferdinand Maximilian of Habsburg, Thomas Klanf [Secoli 2010]. Secondly, it has been documented [Secoli 2010] the fact that the laborious Furlans seems to be not so able to cope the clanfa tuff stategy,
remeding often a dolorous panzada, or -more tragically- a great musada on the asfalt of the LittleRats. The musada is very harmful for the laborious Furlan, because it prevents the possibility for the victim to work hard all along the period of degenz in Cattinara Intensive Care Unit.
The present paper investigates on the possible reasons why Furlans and Triestins seems to exhibit such a great difference in performing clanfa.

Ten adult males, while cammining for the strad, were recruited and were asked to partecipate to a scientific experiments. They were asked to complete the following questionnaire:
1) Go con mi tre grandi afeti, quando vado a …… (fill in the correct answer)
2) Ce mut la bighe? Cjalde ma …… (fill in the correct answer)
The males were divided into two groups, according to the answers provided to the questions. Five of them answered correctly to the first question and leave the second question in white; they were labeled “group t”, as Triestins. Dually, the other five males correctly answered to the second question, but not to the first one; they were associated to the branch “f” (as Furlans) of the trial.
After recruiting, the participant started to follow a cultural / enogastronomical / educational protocol, hereby described.
· 1st day. To go with the calm to Barcola Beach LittleRats number 7 and to perform a clanfa, even a là va là che te va ben. The heights of the schizz were recorded.
· 2nd day. Not to make a kuraz. To walk around along the betole of Saint James Field, and to drink sprizzini e otavi a nastro, singing typical petessons songs.
· 3rd day. To spav all the day. To give a cuc very attently to the video Corso Clanfe Sunshine [Pecile 2007].
· 4th day. To go with much calm to Barcola Beach LittleRats number 7 and to perform the second clanfa. The heights of the schizz were recorded.
· 5th day. Not to make a clinz all the day, convincing oneself about to the possibility that if the clanfa riesc well, it is very probable that the mule will give it you without paying (as conversely happens in the Bunga Bunga land).
· 6th day. To go without hurry to Barcola Beach LittleRats number 7 and to perform the third clanfa. The heights of the schizz were recorded.
· 7th day. To stay all the day on the divan studying all details about life, death and miracles of Thomas Klanf, the famous maggiordom of Miramare Castle.
· 8th day. To stay seated all the day at Joseph the Slave, eating boiled pork in all the possible manner: Wiener sausages, Cragner sausages, Porklet, Orec, Ling, Pièdin, and so on and so forth, with capootzee, senap and cren.
· 9th day. To go to Saint Just staying sitted on a mureto to breathe the pure Triestin borinèto, to listen to the celestial song of the big càmpan, and to contemplate the alabard over the melon dreaming the old times in which Cabibis lived in southern Italy and Slaves lived out of Piazza Dalmazia (more precisely, from behind Cafè Fabris to Vladìvostok [Strukelj 2010]).
· 10th day. To go very slow to Barcola Beach LittleRats number 7 and to perform the fourth clanfa. The heights of the schizz were recorded.
· 11th day. To cazzeggiate walking all along the RedBridge, and repeating a ufete that Austria was an ordered Country, taking some photo ricord with the bronz statue of James Zois (father of Žiga Joyce).
· 12th day. To go with the fiacheta to Barcola Beach LittleRats number 7 and to perform the fifth clanfa. The heights of the schizz were recorded.
· 13th day. To stay during the morning in Public Garden (between via GreatMarks and via July), watching the video of the Olimpiadi de la clanfa, to go to Barcola Beach LittleRats number 7 and to perform the sixth clanfa. The heights of the schizz were recorded.
· 14th day. Not to make one pipe all the day. To go to the casinò of PinksHarbour for a briscola and threeseven tournament (dumb mugs are allowed, to knock and to stripe as well).
· 15th (last and not list) day. Surrounded by the most famous Misses LittleRats, to go to Barcola Beach LittleRats number 7 and to perform the seventh and ultimate clanfa. The heights of the schizz were recorded. To conged the participants and to declare finished the clinical trial, publishing the results, and
to go with God.
Being the present trial a pilot study, no power analysis was conducted in advance, and consequently the sample size was determined at eye, ciaping the first disgraziai passing there randomly. Statistical analysis were conducted by R package [R 2009 ].
Normality in data distribution was visually investigated by QQ plot and assessed by means of Shapiro-Wilk test. In normally distributed data (Shapiro-Wilk test p ³ 0.05) homoskedasticity was assessed by means of Fisher-Snedecor F test and consequently (Fisher-Snedecor F test p ³ 0.05) difference in means was checked by Student-Welch ttest. In not normally distributed data (Shapiro-Wilk test p < 0.05), homoskedasticity
was assessed by means of Fligner-Killeen homogeneity of variances test [Conover 1981] and consequently (Fligner-Killeen test p ³ 0.05) difference in centrality was checked by Wilcoxon rank sum test.
In comparison between groups (Student-Welch of Wilcoxon-Mann-Whitney, according respectively to presence or lack of normality) to assess superior performances one tail test were performed, and consequently the significance level was halved (i.e. effect was declared significant if p < 0.025).
Data were summarized by Tukey five numbers description and depicted by boxplots.
The longitudinal time nonlinear performance of the trial was analyzed by a nonlinear random mixed-effect modelling method [Pinheiro 2000] applying the R package nlme [nlme 2010].
Raw data and the complete R code used in the analyses are reported and freely scarigable from the clanfastatistica.altervista.org website.

The 5 + 5 participants of the two balanced branch of the trial were biometrically paragonable with respect to heights and weights, as reported in table 1.
The analysis of the heights of the schizz disclosed that results achieved by the Triestins group was significantly superior to the results exhibited by Furlans group, as reported in table 2 and depicted in figure 1.

Figure 1. Visualization of the performance of the Furlans group against to that of the Triestins. As clearly evidenced, the Triestins (nonlinear) growth rate in height of the schizz during the central time of the experiment is definitely superiour to that of the Furlans participating to Clanfa Trial.

Moved by the very interesting performances shown by the Triestins group, we investigated the possibility to describe the phenomenon by means of a nonlinear random effect mixed model. The complete dataset clanfatriestins.txt is freely downloadable from the clanfastatistica.altervista.org website, and the R line commands have been reported both in supplementary materal and on the website, in a cut-and-paste format ready to repeat the analysis. We assumed that time profile can be modeled as a logistic curve [Pinheiro 2000] of equation:

Therefore, the ij y height of the schizz performed by the i-th Triestin partecipant, measured during the j-th occasion (in this trial t t {0,4,6,10,12,13,15} ij j º Î ) varies in a nonlilnear way according (possible) three random parameters linked to the subject: 1f represents the asymptotic level of the schizz achievable by each participant, 2f is the motivation (i.e. voia) that each participant has in succeeding in the trial and 3f is
related to the neurocognitive ability (i.e. zervel) possessed by the subject to emulate the example provided by the protocol; ij e represents the zero mean valued normally distributed residual variability not explained by the model.
We explored Model 1, assuming respectively 1f 2f and 3f as indipendent random effect, and Model 2, with only 1f as a random effect. A (restricted) log-likelihood test, as reported in Table 3, disclosed that Model B was the preferred one for its parsimony. In figure 2 the regression curves are depicted.

At our best knowledge, the Clanfa Trial represents the first experiment appeared in literature which demonstrates that Triestin males achieves superior results than the Furlans in this particular endemic behavior. Due to the fact that the participants were paragonable both in stature than in weigth, we recognize that the reason why Furlans did not outperfom in clanfa tuff must be ulteriorly investigated, being not linked to their biometric features. Therefore, we encourage scholars to consider a wider neuroscientific and/or socioeconomic approach in their investigatory sforz.

    veramente el gavessi dimostrà che 5 triestini (ciolti a caso me auguro)ma che camina etc etc, ciè 5 triestini che camina per strada xè più clanfadori dei furlani , me par che questo xe el risultato e magari ragionar come saria sta ciolendo 5 triestini non vincolai al fato de camina, saria una roba più meio forsi o no? (prima parte del referee)

  2. kaiokasin ha detto:

    Un che traduci Topolini con LittleRats anzichè el coreto LittleMouse, per mi no gà nisuna valenza sientifica. In materia de clanfistica teorica mi resto fedele ala scola classica diegomannista. Per risolver la questiòn tra i due luminari ghe volessi organizar un simposio de clanfistica applicata al ultimo topolin, pena che fa più caldo, e dopo veder chi che schizza de più.

    Aldo Rogna for Nobel Prize, Diego Manna for President !!!
    🙂 🙂 🙂

  5. Fiora ha detto:

    LITTLERATS a mi me sona ‘ssai ben, ma xè l’insieme che per esser giocoso se addentra talmente tanto de perder quella lievità che fa l’unicità Diegomannesca che tanto cattura…
    Ma xè question de gusti e anche questo xè un bel lavor!

  6. kaiokasin ha detto:

    Volevo solo vivacizzar el dibatito (e rivar ai 100 comenti), ma anche a Ronald Hassle (?) the Fisher la mia gratitudine per il suo contributo alla scienza. Per el nobel vedemo (i gà proposto Berluska, no vedo perchè no Aldo).

  7. Diego Manna ha detto:

    per rivar a 100 comenti xe de far un studio su tito e le foibe, se no nema 😉
