Ancient Principles for the Digital Age: Truth and Ethics for Writing on the Web
Education in 2030 will undergo huge changes with generation Z in the classroom. The āreal digital nativesā will influence economic structures as well as the educational system due to their online behaviour and increased use of technology. Teachers at the tertiary level have to be prepared for this generation, especially when integrating social media in their instruction. They have to be aware of the main differences between web writing and paper writing when it comes to blogs, wikis, eportfolios and threaded discussions in online forums. As every single person constitutes a public digital identity in social media, teachers have to know online writing competencies in order to take responsibility for their own online performance and those of their students, especially within the increasing debate of fake news. The ancient principles of truth and ethics in online media are more than ever the reliable basis for collaborative work. The EU funded project within Erasmus+, āFuture-proof your classroom ā teaching skills 2030ā, elaborates on these competencies in order to equip teachers with digital reading and writing skills in a blended-learning course.

Technology meets Psychology: Teaching Business Students Critical Thinking within New Learning Formats
With the increasing use of technology in education, one may ask if psychological subjects with a huge amount of personal involvement are suitable for teaching within technology based learning formats. The UAS Burgenland redesigned the course āCritical Thinkingā for part-time business students to reflect on leadership and intercultural communication using a blended learning format. This paper (presentation) elaborates on the requirements when teaching psychological topics and combining on-campus training with virtual classrooms. Succeeding in this effort means selecting very specific exercises and tasks in the diverse phases, linking them properly, adjusting the feedback processes and being aware of the diverse roles as a coach and moderator. Results have shown that students value the combination of various teaching methods as long as they feel safe within their self-development. Moreover, they are motivated to participate in virtual classrooms as the physical distance provides them with a sense of security in contrast to on-campus classes. The course āCritical Thinkingā aims to provide a model for teaching psychological subjects within technology based education.

Verbalna memorija u bolesnika nakon operacije rupturirane i nerupturirane cerebralne aneurizme
A cerebral aneurysm is a bulge in the wall of a brain blood vessel with a risk to rupture. It occurs in about 2% of the population, somewhat more often in women. Most aneurysms are located in the anterior circulation area. Aneurysm rupture is relatively rare and accounts for 5% of all cerebrovascular brain incidents. Ruptured and asymptomatic/unruptured aneurysms are often treated surgically at the Department of Neurosurgery, Medical School University of Zagreb. The study included 134 patients after cerebral aneurysm surgery during the last 10 years, and neuropsychological testing was performed on average 77 days after surgery. The average age was 52 years and they completed an average of 12 years of education. In the group of patients included in this study, 40.3% of them were operated after ruptured, and 59.7% for unruptured cerebral aneurysm. Most aneurysms were located in the middle cerebral and anterior communicating arteries. With regard to lateralization, there was an equal number of aneurysms located in the right and left hemisphere and bilaterally (on the anterior communicating artery). As part of regular neuropsychological assessment, tests of verbal learning and memory (numerical, logical and mechanical memory) were applied. The aims of the study were to find out whether patients operated for ruptured cerebral aneurysms show greater verbal memory impairments than patients operated for unruptured cerebral aneurysms and whether there was the significant effect of lateralization of aneurysm (to check the interaction effect of both rupture and lateralization on those functions). The results obtained show that, even though there are no statistically significant differences between groups of patients that underwent surgery for ruptured and unruptured brain aneurysm, patients show a trend of somewhat better results on most of the verbal memory functions after surgery for unruptured brain aneurysm. The results show statistically significant difference between groups of patients that underwent surgery for ACoA aneurysm and those with right lateralized cerebral aneurysms on most of the trails on AVLT test. Also, patients with operated ACoA aneurysm have significantly worse scores in learning process (AVLT 3 and AVLT 4) and especially on short-term and long-term verbal memory than the patients who were operated for left or right lateralized aneurysm.Cerebralna aneurizma je proÅ”irenje cerebralne krvne žile kod kojeg postoji vjerojatnost rupture. Javlja se u oko 2% populacije, neÅ”to ÄeÅ”Äe kod žena, a veÄina je smjeÅ”tena je u podruÄju prednje cirkulacije. Ruptura aneurizme je relativno rijetka i predstavlja 5% svih cerebrovaskularnih moždanih incidenata. U Klinici za neurokirurgiju Medicinskog fakulteta SveuÄiliÅ”ta u Zagrebu Äesto se operativno lijeÄe rupturirane, ali i asimptomatske/nerupturirane aneurizme. U ovo istraživanje ukljuÄeno je 134 bolesnika operiranih u zadnjih 10 godina, kod kojih je neuropsihologijsko testiranje provedeno u prosjeku 77 dana nakon operacije. ProsjeÄna životna dob ispitanika je bila 52 godine te u prosjeku imaju 12 godina Å”kolovanja. U skupini bolesnika ukljuÄenih u ovo istraživanje 40.3% bolesnika operirano je nakon rupture aneurizme, a 59,7% bolesnika operirano je zbog nerupturirane aneurizme. NajviÅ”e je aneurizmi bilo smjeÅ”teno na srednjoj mozgovnoj i prednjoj komunikantnoj arteriji. S obzirom na lateralizaciju, bio je podjednak broj aneurizmi smjeÅ”tenih u desnoj i lijevoj hemisferi odnosno bilateralno (na prednjoj komunikantnoj arteriji). U okviru redovne neuropsihologijske obrade primijenjeni su testovi verbalnog uÄenja i pamÄenja (numeriÄko, logiÄko i mehaniÄko pamÄenje). Cilj istraživanja bio je ustanoviti postoji li razlika u deficitima verbalnog pamÄenja u bolesnika nakon operacije rupturiranih i nerupturiranih aneurizmi te postoji li znaÄajan uÄinak lateralizacije aneurizme (provjeriti interakcijski uÄinak rupture i lateralizacije na te funkcije). Dobiveni rezultati su pokazali da, iako nisu utvrÄene statistiÄki znaÄajne razlike izmeÄu skupine bolesnika operiranih nakon rupturirane aneurizme i nerupturirane aneurizme, u veÄini ispitivanih funkcija bolesnici nakon operacije rupturirane aneurizme postižu neÅ”to niže rezultate. Rezultati pokazuju statistiÄki znaÄajnu razliku izmeÄu skupina pacijenata koji su operirani zbog ACoA aneurizme i onih s desnim lateralnim cerebralnim aneurizmama na veÄini ponavljanja na AVLT testu. TakoÄer, pacijenti s operiranom ACoA aneurizmom imaju znaÄajno loÅ”ije rezultate u procesu uÄenja (AVLT3 i AVLT4), a posebno na kratkotroÄnom i dugoroÄnom verbalnom pamÄenju od pacijenata koji su operirani zbog aneurizme smjeÅ”tene u lijevoj ili desnoj mozgovnoj hemisferi
OGRE: Overlap Graph-based metagenomic Read clustEring
The microbes that live in an environment can be identified from the genomic material that is present, also referred to as the metagenome. Using Next Generation Sequencing techniques this genomic material can be obtained from the environment, resulting in a large set of sequencing reads. A proper assembly of these reads into contigs or even full genomes allows one to identify the microbial species and strains that live in the environment. Assembling a metagenome is a challenging task and can benefit from clustering the reads into species-specific bins prior to assembly. In this paper we propose OGRE, an Overlap-Graph based Read clustEring procedure for metagenomic read data. OGRE is the only method that can successfully cluster reads in species-specific bins for large metagenomic datasets without running into computation time- or memory issues
Ekstremna hiperkalemija u starije bolesnice uzrokovana nesteroidnim antireumatikom i ACE-inhibitorom
Extreme hyperkalaemia is a life-threatening electrolyte disorder. It is relatively common in patients with severe renal insuffi ciency. This report describes a case of extreme hyperkalaemia caused by drugs in
an 82-year-old female patient without severe renal insuffi ciency, who was successfully treated without haemodialysis. The patient had been treated for arterial hypertension and type 2 diabetes mellitus for 30 years. Over the last years she had been receiving enalapril and metformin. Three weeks before the admission to the hospital, she was receiving a non-steroidal anti-infl ammatory drug (NSAID) because of the back pain.
She was admitted to hospital due to a collapse and weakness in the limbs. Laboratory tests showed extreme hyperkalaemia, high blood sugar, metabolic acidosis, elevated serum creatinine and blood urea nitrogen (BUN), and a slightly elevated serum sodium. On ECG, we noticed typical signs of hyperkalaemia.
The patient was treated with a slow intravenous bolus of calcium gluconate and intravenous infusion of sodium chloride with insulin, glucose with insulin and sodium bicarbonte. After the treatment, all laboratory fi ndings normalised together and the patient felt better. This case shows that physicians should be very careful when prescribing NSAIDs to elderly patients treated with drugs that affect renal function.Ekstremna hiperkalemija je za život opasan poremeÄaj elektrolita. Relativno je Äesta u bolesnika s teÅ”kim bubrežnim zatajivanjem. Ovaj prikaz opisuje sluÄaj ekstremne hiperkalemije uzrokovane lijekovima u 82-godiÅ”nje bolesnice bez težega bubrežnog zatajivanja, a koja je bila uspjeÅ”no lijeÄena bez hemodijalize.
Bolesnica je unatrag 30 godina bila lijeÄena zbog poviÅ”enoga krvnog tlaka i Å”eÄerne bolesti. Zbog arterijske hipertenzije uzimala je enalapril, a zbog Å”eÄerne bolesti metformin. Tri tjedna prije hospitalizacije uzimala je nesteroidni antireumatik zbog bolova u leÄima. Bolesnica je bila primljena u bolnicu nakon Å”to je kolabirala uz osjeÄaj izrazite slabosti u udovima. U laboratorijskim nalazima bile su prisutne ekstremna hiperkalemija, hiperglikemija, metaboliÄka acidoza, poviÅ”ene razine serumskog kreatinina i ureje te blago poviÅ”ena vrijednost serumskog natrija. Na EKG-u su bili registrirani tipiÄni znakovi hiperkalemije.
Bolesnica je bila lijeÄena polaganim bolusom kalcijeva glukonata, intravenskim infuzijama natrijeva klorida uz inzulin, otopinom glukoze uz inzulin i otopinom natrijeva bikarbonata. LijeÄenjem su se
laboratorijski nalazi normalizirali uz poboljÅ”anje subjektivnoga stanja bolesnice. Ovaj prikaz upozorava na to da lijeÄnici moraju biti vrlo oprezni pri propisivanju nesteroidnih antireumatika starijim bolesnicima lijeÄenima lijekovima koji mogu utjecati na bubrežnu funkciju
Die qualitative und quantitative Analyse des Benton-Tests zur Ermittlung des visuellen GedƤchtnisvermƶgens bei Patienten mit GehirnschƤden
Cilj ovog rada bio je provjeriti može li Bentonov test vidnog
pamÄenja, uz dijagnosticiranje vidnoperceptivnog, mnestiÄkog i
konstrukcijskog deficita, poslužiti i u svrhu diferencijalne dijagnostike
bolesnika s oÅ”teÄenjima razliÄite etiologije (traume, tumori,
vaskularni poremeÄaji) i razliÄite lateralizacije lezije (lijeva-desna
hemisfera) te postoje li razlike u uratku na ovom testu s obzirom
na spol. Nakon provedenog individualnog ispitivanja na 96 bolesnika
s mozgovnim oÅ”teÄenjima zbog traume, tumora ili vaskularnog
poremeÄaja u KBC āRebroā, uratke ispitanika evaluirali
smo rabeÄi tri mjere: broj toÄnih odgovora, ukupan broj pogreÅ”aka
te vrstu pogreŔaka. Na osnovi provedene složene analize
varijance (2x2x3, lateralizacija ozljede x spol x vrsta mozgovnog
oÅ”teÄenja) utvrdili smo da nema znaÄajnih F-omjera za varijable
broj toÄnih odgovora i broj pogreÅ”aka. Nisu utvrÄeni znaÄajni
glavni efekti dijagnostiÄkih kategorija, strane lezije i spola. Kod
analize vrsta pogreÅ”aka jedini znaÄajan F-omjer (F=5.639, p=
0.020) javio se kod pogreŔaka perseveracije kojih ima viŔe kod
bolesnika s lezijama u lijevoj hemisferi (ML =1.08) nego kod onih
s lezijama u desnoj hemisferi (MD =0.62). Ni jedan drugi glavni
efekt niti interakcija nisu dosegli razinu znaÄajnosti. Stoga se
može preporuÄiti uporaba Bentonovog testa vidnog pamÄenja u
svrhu dijagnosticiranja deficita u funkcijama koje zahvaÄa, no ne
u svrhu diferencijalne dijagnostike, niti je moguÄe na osnovi rezultata
na tom testu donositi zakljuÄke o lateralizaciji ozljede.The aims of this paper are: first: to examine whether Benton
Visual Retention Test can be applied not only in diagnosing
visual-perceptive, mnemonic and construction deficit, but
also in differential diagnostics in patients with brain damage
of different ethiology (traumas, tumors, vascular disorders)
and different lateralization of lesions (left and right brain hemisphere), and second: to find out whether there are
some differences in the test results regarding the sex of the
tested persons. Having carried out individual tests on 95
patients with brain damage caused by trauma, cancer or
vascular disorders in the KBC āRebroā, we have applied
three criteria in the evaluation of the test results: the number
of correct answers, total number of errors, and the type of
errors. Based on a multiple ANOVA (2x2x3, lateralization of
damage x sex x type of brain damage), it has been
determined that there are no significant F-rates for the two
variables: number of correct answers and number of errors.
No significant main effects of the diagnostic categories
lateralization of lesion and sex have been observed. The
analysis of the type of errors shows only one significant Fratio
(F=5.639, p=0.020) in perseveration errors. More
perseveration errors have been observed in patients with
lesions in the left hemisphere (ML =1.08) than in patients
with lesions in the right hemisphere (MD =0.62). No other
main effects and no other interactions have been found to be
significant. The obtained results lead to the conclusion that
Benton Visual Retention Test can be recommended for
diagnostics of deficiencies in the functions it examines, but it
should not be applied for differential diagnostics, nor does it
allow conclusions about the lateralization of lesions.Diese Arbeit soll prĆ¼fen, ob der Benton-Test zur Ermittlung
des visuellen GedƤchtnisvermƶgens ā auĆer zur
Diagnostizierung von visuell-perzeptiven, mnestischen und
konstruktionsbedingten Defiziten ā auch zum Zwecke einer
differenziellen Diagnostik bei Patienten beitragen kann, bei
denen SchƤdigungen unterschiedlicher Ćtiologie (Traumata,
Tumore, vaskulƤre Stƶrungen) sowie Lateralisationen (infolge
von LƤsionen der rechten oder linken HemisphƤre) vorliegen.
Ebenso soll geprĆ¼ft werden, ob es in dieser Hinsicht
Unterschiede zwischen weiblichen und mƤnnlichen Patienten
gibt. Nach jeweils individuell durchgefĆ¼hrten
Untersuchungen an 96 Patienten des Zagreber Klinikums
Rebro, die GehirnschƤden infolge von Traumata, Tumoren oder vaskulƤren Stƶrungen aufwiesen, wurden die
Testergebnisse anhand dreier Faktoren ausgewertet: Zahl der
richtigen Antworten, Gesamtzahl der Fehler sowie die Art der
Fehler. Aufgrund einer komplexen Varianzanalyse (2 x 2 x 3,
lateralisierte Auswirkung einer SchƤdigung x Geschlecht x Art
des Gehirnschadens) kamen die Autorinnen zu dem Schluss,
dass keine bedeutenden F-VerhƤltnisse zu den Variablen der
Zahl der richtigen Antworten sowie der Zahl der Fehler
vorliegen. Es konnten keine bedeutenden Auswirkungen der
diagnostischen Kategorien, der LƤsionsseite und der
Geschlechtszugehƶrigkeit ermittelt werden. Die Analyse des
Fehlertyps ergab ein einziges relevantes F-VerhƤltnis (F =
5.639, p = 0.020), und zwar bei Fehlern vom Typus der
Perseveration, die eher bei Patienten auftreten, die an
LƤsionen der linken HemisphƤre leiden (ML = 1.08), als bei
Patienten mit LƤsionen der rechten HemisphƤre (MD =
0.62). Keine weitere Auswirkung noch irgendeine Interaktion
haben sich von Bedeutung erwiesen. Aufgrund der erzielten
Ergebnisse kann der Benton-Test durchaus zur Ermittlung des
visuellen GedƤchtnisvermƶgens sowie zur Diagnostizierung
von FunktionsmƤngeln empfohlen werden. Der Test eignet
sich jedoch nicht zum Zweck einer Differenzdiagnostik, noch
aber lassen die Testergebnisse SchlĆ¼sse Ć¼ber die
Lateralisierung einer LƤsion zu
Leveraging the power of place in citizen science for effective conservation decision making
Many citizen science projects are place-based - built on in-person participation and motivated by local conservation. When done thoughtfully, this approach to citizen science can transform humans and their environment. Despite such possibilities, many projects struggle to meet decision-maker needs, generate useful data to inform decisions, and improve social-ecological resilience. Here, we define leveraging the āpower of placeā in citizen science, and posit that doing this improves conservation decision making, increases participation, and improves community resilience. First, we explore āplaceā and identify five place dimensions: social-ecological, narrative and name-based, knowledge-based, emotional and affective, and performative. We then thematically analyze 134 case studies drawn from CitSci.org (n = 39), The Stewardship Network New England (TSN-NE; n = 39), and Earthwatch (n = 56) regarding: (1) use of place dimensions in materials (as one indication of leveraging the power of place), (2) intent for use of data in decision-making, and (3) evidence of such use. We find that 89% of projects intend for data to be used, 46% demonstrate no evidence of use, and 54% provide some evidence of use. Moreover, projects used in decision making leverage more (t = ā 4.8, df = 117; p \u3c 0.001) place dimensions (= 3.0; s = 1.4) than those not used in decision making (= 1.8; s = 1.2). Further, a Principal Components Analysis identifies three related components (aesthetic, narrative and name-based, and social-ecological). Given these findings, we present a framework for leveraging place in citizen science projects and platforms, and recommend approaches to better impart intended outcomes. We discuss place in citizen science related to relevance, participation, resilience, and scalability and conclude that effective decision making as a means towards more resilient and sustainable communities can be strengthened by leveraging the power of place in citizen science
The Power of Place in Citizen Science
