First-year college students’ weight change is influenced by their randomly assigned roommates’ BMI
Authors: van Woerden Irene , Hruschka Daniel , Brewis Alexandra , Schaefer David R. , Bruening Meg
Published: November 2020

Background

There is ongoing debate about whether friends’ greater similarity in Body Mass Index (BMI) than non-friends is due to friend selection, shared environments, or peer influence.

Methods

First-year college students (n = 104) from a southwestern U.S. university were randomly assigned roommates during the university’s housing process, effectively removing friend selection effects. Participant BMI was measured up to four times (T1-T4) across 2015–2016. The influence of roommate baseline BMI (T1) on change in participant BMI over time (T2-T4) was analyzed using a linear mixed effects model adjusted for individual socio-demographics, linear time trends, baseline BMI, and physical clustering of students. A sensitivity analysis examining floormates was also conducted.

Results

Consistent with roommate influence, participants randomized to roommates with a higher BMI gained more weight between times T2 and T4 (β = 0.06; 95% CI = 0.02, 0.10). No shared environment effects (shared campus or floor) were found.

Conclusions

Randomly assigned roommates influenced each other's weight trajectories. This clarifies that BMI convergence can occur outside of friend selection or shared environments mechanisms.

The potential hazard to human health from exposure to heavy metals in surface soil was assessed using 66 soil samples collected from Ahvaz oil field. To this end, the contents of heavy metals were measured by the inductively coupled plasma spectroscopy (ICP-OES). Mean levels of As, Cd, Co, Cr, Cu, Ni, Pb, V, and Zn were 5.9, 0.4, 7.1, 36.5, 41.2, 39.8, 67.4, 31.5, and 77.6 mg/kg, respectively. Contents of all studied heavy metals, with the exception of Co, Cr, and V, were several times higher than that of baselines. Correlation coefficients and principal component analysis (PCA) identified two main groups as sources of heavy metals in the surface soil of Ahvaz oil-field. Metals such as Co, Cr, and V were observed to originate from natural sources and As, Cd, Cu, Ni, Pb, and Zn originated from anthropogenic sources such as petroleum leakage and the pollution caused by drilling mud from oil wells. Pb and Zn were of significantly high EF mean enrichment value, and Co, Cu, Cd, and As had high enrichment in surface soil. Pb, Cr, V, Zn, Co, Cu, Ni, and As had a low potential ecological risk (PER) whereas Cd had a moderate PER. The risk of carcinogenic and non-carcinogenic diseases was detected to be higher in children than in adults. The carcinogenic risk (Cr) calculation was more than 1 × 10-6 for children and adults. Additionally, the CR of Cr for both children and adults indicated risk under control conditions.

Exosomes are a type of extracellular vesicles (EVs) secreted by multiple mammalian cell types and involved in intercellular communication. Numerous studies have explored the diagnostic and therapeutic potential of exosomes. The key challenge is the lack of efficient and standard techniques for isolation and downstream analysis of nanovesicles. Conventional isolation methods, such as ultracentrifugation, precipitation, filtration, chromatography, and immune-affinity-based approaches, rely on specific physical properties or on surface biomarkers. However, any of the existing methods has its limitations. Various parameters, such as efficacy, specificity, labor input, cost and scalability, and standardization options, must be considered for the correct choice of appropriate approach. The isolation of exosomes from biological fluids is especially challenged by the complex nature and variability of these liquids. Here, we present a comparison of five protocols for exosome isolation from human plasma: two chemical affinity precipitation methods (lectin-based purification and SubX™ technology), immunoaffinity precipitation, and reference ultracentrifugation-based exosome isolation method in two modifications. An approach for the isolation of exosomes based on the phenomenon of binding and aggregation of these particles via clusters of outer membrane phosphate groups in the presence of SubX™ molecules has been put forward in the present study. The isolated EVs were characterized based upon size, quantity, and protein content.

Background

J wave syndromes (JWS), including Brugada (BrS) and early repolarization syndromes (ERS), are associated with increased risk for life-threatening ventricular arrhythmias. Pharmacologic approaches to therapy are currently very limited. Here, we evaluate the effects of the natural flavone acacetin.

Methods

The effects of acacetin on action potential (AP) morphology and transient outward current (Ito) were first studied in isolated canine RV epicardial myocytes using whole-cell patch clamp techniques. Acacetin’s effects on transmembrane APs, unipolar electrograms and transmural ECGs were then studied in isolated coronary-perfused canine RV and LV wedge preparations as well as in whole-heart, Langendorff-perfused preparations from which we recorded a 12 lead ECG and unipolar electrograms. Using floating glass microelectrodes we also recorded transmembrane APs from the RVOT of the whole-heart model. The Itoagonist NS5806, sodium channel blocker ajmaline, calcium channel blocker verapamil or hypothermia (32°C) were used to pharmacologically mimic the genetic defects and conditions associated with JWS, thus eliciting prominent J waves and provoking VT/VF.

Results

Acacetin (5–10 μM) reduced Itodensity, AP notch and J wave area and totally suppressed the electrocardiographic and arrhythmic manifestation of both BrS and ERS, regardless of the experimental model used. In wedge and whole-heart models of JWS, increasing Itowith NS5806, decreasing INaor ICa(with ajmaline or verapamil) or hypothermia all resulted in accentuation of epicardial AP notch and ECG J waves, resulting in characteristic BrS and ERS phenotypes. Phase 2-reentrant extrasystoles originating from the RVOT triggered VT/VF. The J waves in leads V1 and V2 were never associated with a delay of RVOT activation and always coincided with the appearance of the AP notch recorded from RVOT epicardium. All repolarization defects giving rise to VT/VF in the BrS and ERS models were reversed by acacetin, resulting in total suppression of VT/VF.

Conclusions

We present experimental models of BrS and ERS capable of recapitulating all of the ECG and arrhythmic manifestations of the JWS. Our findings provide definitive support for the repolarization but not the depolarization hypothesis proposed to underlie BrS and point to acacetin as a promising new pharmacologic treatment for JWS.

Published: November 2020

Background

In recent years, sentinel lymph node excision and ultrastaging have been performed in endometrial carcinomas to obtain information about lymph node status, avoiding unnecessary complete pelvic and paraaortic lymphadenectomy. The purpose of this retrospective study was to provide a comprehensive evaluation of the pathological features of endometrial carcinomas and their significance in association with sentinel lymph node involvement.

Methods

Patients with endometrial carcinomas, preceded by sentinel lymph node mapping, were classified into Group-I and Group-II with negative and positive involvement, respectively. The pathological features, associated with sentinel lymph node involvement, were statistically analyzed, including determination of test performance parameters.

Results

Among 70 patients who had undergone hysterectomy and sentinel lymph node excision, 61 had carcinoma and 9 had atypical hyperplasia. There were 50 patients in Group-I and 10 in Group-II. In Group-II, the significant pathological features were: 1) lower uterine segment involvement (100%), 2) an average tumor size of ≥5 CM, 3) lymphovascular invasion (50%), 4) cervical stromal invasion (40%), and 5) depth of myometrial invasion of ≥50% (50%). The incidences of these pathological features were significantly less in Group-I. Statistical analyses singled out “lower uterine segment involvement” as the most important feature.

Conclusions

We have identified five pathological features which are associated with sentinel lymph node involvement. Since lower uterine segment involvement has occurred in all cases of the Group-II cohort, we recommend FIGO and other organizations that determine staging rules should consider whether tumors that involve the lower uterine segment should be staged as higher than “1a”, if the findings in this small series are confirmed by other studies. The results of this study may guide pathologists and oncologists in the diagnostic and therapeutic approaches to management of endometrial carcinomas.

Published: November 2020

Background

Tobacco, alcohol, and marijuana are the top three substances used by adolescents. The adverse health effects of these three substances are well documented in epidemiological literature, yet little is known about the substance use and associated factors among adolescents in Bangladesh. This study examines the risk factors for tobacco and other substances use among school-going adolescents in Bangladesh.

Methods

We analyzed data from the 2014 Bangladesh Global School-based Student Health Survey (GSHS) of adolescents aged 13–17 years. We used two outcome measures: tobacco use (TU) and other substance use (SU; alcohol and/or marijuana). We examined a set of reported psychosocial and socio-environmental adverse events as risk factors. Logistic regression analyses were used to identify associations.

Results

The prevalence of TU and other SU among school-going adolescents was 9.6% and 2.3%, respectively. The likelihood of TU and other SU was higher among adolescents who reported being bullied (TU: adjusted odd ratio [AOR]: 1.93; 95% confidence interval [CI]: 1.24–3.00; and other SU: AOR: 3.43; 95% CI: 1.46–7.99) and having sexual history (TU: AOR: 19.38; 95% CI: 12.43–30.21; and other SU: AOR: 5.34; 95% CI: 2.17–13.29). Moreover, anxiety-related sleep loss was associated with adolescents’ TU (AOR: 2.41; 95% CI: 1.02–5.82) whereas the likelihood of other SU (AOR: 3.27; 95% CI: 1.14–9.44) was higher among lonely adolescents. Experience of adverse socio-environmental factors, such as parental substance use (TU: AOR: 7.81; 95% CI: 5.08–12.01), poor monitoring (TU: AOR: 1.96; 95% CI: 1.16–3.31) and poor understanding (TU: AOR: 2.22; 95% CI: 1.36–3.65), and lack of peer support (TU: AOR: 3.13; 95% CI: 1.84–5.31; and other SU: AOR: 2.45; 95% CI: 1.02–5.91), and truancy (other SU: AOR: 4.29; 95% CI: 1.81–10.12) were also positively associated with TU and/or other SU. Additionally, higher odds of tobacco use were observed among adolescents who reported 1 (AOR: 4.36 times; 95% CI: 1.34–14.24), 2 (AOR: 8.69 95% CI: 1.67–28.23), and ≥3 (AOR: 17.46; 95% CI: 6.20–49.23) adverse psychosocial experiences than who did not report any psychosocial events.

Conclusions

Tobacco and other substance use among school-going adolescents are prevalent in Bangladesh. Several psychosocial and socio-environmental events are associated with TU and other SU, which should be incorporated into adolescent substance use and health promotion programs.

Alfred Hitchcock’s Vertigo and the Pygmalion Myth Reconsidered
Authors: Bär Silvio Friedrich
Published: November 2020

Alfred Hitchcock’s film Vertigo (1958) has attracted the interest of classical reception scholars because of its adaptation of Ovid’s Pygmalion myth. Scottie, the film’s main character, has been interpreted as a re-enactment of Pygmalion, a character in the Metamorphoses who sculpted his ideal woman out of ivory. In this article, the idea of a direct line of reception from Ovid to Hitchcock is challenged. Rather, the principal model of the film is identified as George Bernard Shaw’s drama Pygmalion (1913). However, Ovid’s Pygmalion story does constitute a model for the film as well, though it does so on a more indirect level. In fact, all the film’s main characters display Ovidian traits. These add an extra layer of meaning to the understanding of the film and the complexity of its characters, and allow for an unexpected re-interpretation of Scottie and his desires.
A fenntarthatósági lábnyom-megközelítések szerepe a vállalatok fenntarthatósági szempontú teljesítményértékelésében

A vállalati fenntarthatósági teljesítményértékelésre vonatkozóan számtalan megközelítés és módszer létezik. Ez a cikk a lábnyomtípusú fenntarthatósági mutatók vállalati teljesítményértékelésben betöltött szerepéről kíván összegző áttekintést nyújtani. A lábnyomtípusú mutatók alkalmazásával kapcsolatban számos elméleti modell és gyakorlati tapasztalat áll rendelkezésre, ezek ugyanakkor kevéssé foglalkoznak a lábnyom-megközelítések szervezeti szintű alkalmazásával, illetve annak rendszerszintű áttekintésével. E cikkben ezért a szerzők felvázolnak egy keretrendszert a vállalati fenntarthatósági lábnyom-indikátorok értékelésére, amelyen keresztül megvizsgálják a leggyakoribb lábnyom-megközelítések vállalati fenntarthatósági teljesítményértékelésben betöltött lehetséges szerepét. A felvázolt modell kiterjed i) a teljesítményértékelési folyamat tervezésének, ii) az információgyűjtés folyamatának és iii) a teljesítményértékelési rendszer felülvizsgálatának és fejlesztésének belső és külső szempontjaira. Az áttekintés során összesen öt különböző vállalati lábnyomtípust azonosítottak, melyek szervezeti szinten is alkalmazhatóak (karbonlábnyom, ökológiai lábnyom, vízlábnyom, környezeti lábnyom és nitrogénlábnyom). Ezek tartalmukat és módszertani kidolgozottságukat tekintve igen eltérőek. Közös jellemzőjük, hogy a vállalatok és más szervezetek számára lehetőséget adnak a szervezeti szintű fenntarthatósági teljesítményük nyomon követésére, kezelésére és kommunikálására. Mivel a lábnyomok a közvetlen hatások mellett a közvetett hatásokról is képesek információt nyújtani, kulcsszerepet tölthetnek be a szervezeti fenntarthatóság mérésében.
A vezetőképzések szerepe a gazdasági versenyképességben

Published: November 2020

Magyarországon a rendszerváltás után a vezetők részére kidolgozott továbbképzések, tanfolyamok és tréningek szinte önálló képzési ágazattá nőtték ki magukat, amelyben a szolgáltatói oldalon a graduális programokat is kínáló felsőoktatási intézmények, a nyugatról érkező nemzetközi cégek leányvállalatai vagy képviselői, illetve a hazai tréningcégek és magániskolák egyaránt megjelentek. A sokszereplős, de gyengén szabályozott piacon a tanulni vágyók számára egyre nehezebbé vált a minőségi, valós szakmai és néha személyiségfejlődést is biztosító képzések beazonosítása. Az alábbiakban a szerző kísérletet tesz rá, hogy a teljesség igénye nélkül összegyűjtsön néhány olyan szempontot és kritériumot, amely támpontot adhat a képzési programok értékeléséhez. A cikkben az előbbiek mellett szó esik a keresleti oldal differenciált mivoltáról is, ami meghatározza, hogy az azon belül elkülöníthető két főcsoport számára mely programok lesznek megfelelőek.
Exportáló vállalataink sokszínűsége

Published: November 2020

A kutatás az exportáló vállalatok heterogén jellegét mutatja be a vállalati versenyképességi kutatás 2013, 2009, 2004 és 1999-es adatbázisának elemzésén keresztül. A kutatás fő módszertani eleme a K-középpontú klaszterelemzés, ahol az exportteljesítmény mércéi jelentették a klaszterképzés tényezőit. A klaszterelemzés négy klasztert azonosított: "stabil növekedők", "stagnálók", „fejlődő exportálók” és a "kismértékű" exportálók csoportját. A vállalatok pénzügyi teljesítményének elemzése során a klaszterek között szignifikáns jövedelmezőségi különbséget lehetett kimutatni, általánosságban elmondható, hogy a többségi külföldi tulajdonban levő vállalatok jövedelmezősége magasabb, ugyanakkor a legsikeresebb exportáló vállalatcsoporton belül statisztikailag nem lehetett kimutatni a külföldi tulajdonú vállalatok magasabb jövedelmezőségét. A magas exportintenzitással rendelkező "stabil növekedő" és "stagnáló" vállalatok összehasonlítása során a szerző arra a következtetésre jutott, hogy a jobb exportteljesítmény és a magasabb jövedelmezőség hátterében jobb működési jellemzők és jobb menedzsmentképességek állnak.

Assessing for Eating Disorders: A Primer for Gastroenterologists
Authors: Werlang Monia E. , Sim Leslie A. , Lebow Jocelyn R. , Lacy Brian E.
Published: November 2020

Eating disorders involve irregularities in eating behavior that may cause gastrointestinal (GI) symptoms. Consequently, many patients with eating disorders seek gastroenterological healthcare at some point in their illness, with many seeking this care even before they seek treatment for and/or diagnosed with their eating disorder. As such, the gastroenterology provider is in a unique position to identify, manage, and facilitate treatment for an eating disorder early in the course of the illness. Although assessing eating disorders is already a difficult task, the identification of eating disorders in patients with GI disease represents an even greater challenge. In particular, common GI symptoms, such as nausea, vomiting, and bloating, may disguise an eating disorder because these symptoms are often viewed as a sufficient impetus for dietary restriction and subsequent weight loss. In addition, the focus on identifying an organic etiology for the GI symptoms can distract providers from considering an eating disorder. During this prolonged diagnostic evaluation, the eating disorder can progress in severity and become more difficult to treat. Unfortunately, a misconception that hinders eating disorder detection is the notion that the rate or method of weight loss is associated with an eating disorder. Regardless of whether weight loss is slow or rapid, purposeful or accidental, eating disorder behaviors and thought patterns may be present. Unidentified eating disorders are not only dangerous in their own right but also can interfere with effective management of GI disease and its symptoms. As such, it is imperative for the GI provider to remain well versed in the identification of these diseases.

INTRODUCTION:

Using the National Cancer Database, we assessed the relationship between facility overall esophageal adenocarcinoma (EAC) case volume and survival.

METHODS:

We categorized facilities into volume quintiles based on annual EAC patient volume and performed a multivariable Cox proportional hazards regression between facility patient volume and survival.

RESULTS:

In a cohort of 116,675 patients, facilities with higher vs lower (≥25 vs 1–4 cases) annual EAC patient volume demonstrated improved survival (adjusted hazard ratio: 0.80. 95% confidence interval: 0.70–0.91).

DISCUSSION:

This robust volume-outcome effect calls for centralization of care for EAC patients at high annual case volume facilities.
Brain-Derived Neurotrophic Factor/Tropomyosin Receptor Kinase B Signaling Controls Excitability and Long-Term Depression in Oval Nucleus of the BNST

Published: November 2020

Dysregulation of proteins involved in synaptic plasticity is associated with pathologies in the CNS, including psychiatric disorders. The bed nucleus of the stria terminalis (BNST), a brain region of the extended amygdala circuit, has been identified as the critical hub responsible for fear responses related to stress coping and pathologic systems states. Here, we report that one particular nucleus, the oval nucleus of the BNST (ovBNST), is rich in brain-derived neurotrophic factor (BDNF) and tropomyosin receptor kinase B (TrkB) receptor. Whole-cell patch-clamp recordings of neurons from male mouse ovBNSTin vitroshowed that the BDNF/TrkB interaction causes a hyperpolarizing shift of the membrane potential from resting value, mediated by an inwardly rectifying potassium current, resulting in reduced neuronal excitability in all major types of ovBNST neurons. Furthermore, BDNF/TrkB signaling mediated long-term depression (LTD) at postsynaptic sites in ovBNST neurons. LTD of ovBNST neurons was prevented by a BDNF scavenger or in the presence of TrkB inhibitors, indicating the contribution to LTD induction. Our data identify BDNF/TrkB signaling as a critical regulator of synaptic activity in ovBNST, which acts at postsynaptic sites to dampen excitability at short and long time scales. Given the central role of ovBNST in mediating maladaptive behaviors associated with stress exposure, our findings suggest a synaptic entry point of the BDNF/TrkB system for adaptation to stressful environmental encounters.

El humanismo es una categoría esencial a tener en cuenta en el desarrollo integral de profesionales de cualquier campo del conocimiento; sin embargo, reconocemos que no es suficiente la cualificación en áreas disciplinares propias de los saberes específicos; y que es necesario formar a la persona, al ser humano desde una perspectiva integral, al sujeto desde una comprensión holística que conjuga capacidades biogenéticas, epigenéticas, filogenéticas y ontogenéticas en donde lo humano involucra las dimensiones cognitivas, afectivas, valorativas e imaginativas que son las herramientas para interpelar la realidad en los procesos de aprendizaje y relacionamiento con el mundo durante toda la vida. Por lo expuesto, las Instituciones de Educación Superior (IES) no pueden limitarse a la formación exclusiva de saberes y conocimientos técnicos y científicos; sino que han de entender al profesional en formación en cuanto persona que es como un ciudadano que hace parte de una cultura con la que comparte principios y valores ético - morales, que le permiten definir su condición como sujeto político y su desempeño como agente transformador desde la comprensión y tolerancia a las diferencias individuales, culturales, políticas, económicos, ambientales y sociales en un mundo diverso, multicultural, en profunda crisis de valores y cada vez más impactado por la era digital y la tecnología.

La música guarda una estrecha relación con los estados de ánimo y la generación de recuerdos a largo plazo. Al respecto, Avello, Ga- vilan y Abril (2011) explican como a través de la música y la voz se establece una conexión más con el consumidor, que facilita la representa- ción de la marca en su mente y crea asociaciones que ac- tivan directamente las emociones, los sentimientos y las experiencias. Lo anterior abre una ventana de po- sibilidades a nivel del mercadeo y los negocios interna- cionales, para entender que es precisamente a través del conocimiento del consumidor, cómo las marcas entran a comunicarse e interactuar con el mismo público ob- jetivo. Cada vez que el consumidor recuerda el jingle, inconscientemente asocia el producto, lo que lleva a la decisión de compra y consumo.

Published: November 2020

OBJECTIVES:

To determine the association between cytochrome P450 2C19 (CYP2C19) metabolizer status and risk for escitalopram and citalopram, collectively termed (es)citalopram, and sertraline adverse events (AEs) in children.

METHODS:

In this retrospective cohort study, we used deidentified electronic health records linked to DNA. The cohort included children ≤18 years with ≥2 days of (es)citalopram or ≥7 days of sertraline exposure. The primary outcome was AEs assessed by manual chart review. CYP2C19 was genotyped for functional variants (*2, *3, *4, *6, *8, and *17), and individuals were assigned metabolizer status. Association between AEs and metabolizer status was determined by using Cox regression adjusting for age, race, ethnicity, dose, and concomitant CYP2C19-inhibiting medications.

RESULTS:

The cohort included 249 sertraline-exposed and 458 (es)citalopram-exposed children, with a median age of 14.2 years (interquartile range 11.2–16.2) and 13.4 years (interquartile range 10.1–15.9), respectively. Sertraline AEs were more common in normal metabolizers (NMs) compared to poor metabolizers (PMs) or intermediate metabolizers (IMs) (hazard ratio [HR] 1.8; 95% confidence interval [CI] 1.01–3.2; P = .047) in unadjusted analysis and after adjustment (HR 1.9; CI 1.04–3.4; P = .04). For (es)citalopram, more AEs were observed in NMs than PMs and IMs without statistically significant differences (unadjusted HR 1.6; CI 0.95-2.6; P = .08; adjusted HR 1.6; CI 0.95-2.6; P = .08).

CONCLUSIONS:

In contrast to adults, in our pediatric cohort, CYP2C19 NMs experienced increased sertraline AEs than PMs and IMs. (Es)citalopram AEs were not associated with CYP2C19 status in the primary analysis. The mechanism underlying this pediatric-specific finding is unknown but may be related to physiologic differences of adolescence. Further research is required to inform genotype-guided prescribing for these drugs in children.
Relationship between availability of basic amenities and proportion of Slum population in Maharashtra
Authors: Dr. Sakreen Hasan
Published: November 2020

The urban centers offering diverse employment opportunities and means of livelihood are the main centers of attraction for migration. But the availability of infrastructure is low to accommodate the invariably growing population. The access to basic amenities like electricity, drinking water, toilet facility, wastewater outlet and clean fuel are critical determinants of quality of urbanization. And if it lacks, then it would facilitates the growth of slum.  In this paper it being tried to capture the interdependent relationship between basic amenities and slum population residing in the class I towns in Maharashtra; largest slum populated state of India. As the slum is all about the situation or condition in which the people of medium and lower strata are living.

A detailed analysis of proportion of slum population and availability of amenities which includes good housing condition, treated tap water as the source of drinking water, electricity as the source of lightning, households having latrine and bathing facility within the premises, waste water outlet connected to closed drainage, and households availing the banking facilities. This may be a limitation of the study that only these indicators have been taken to assess the availability of amenities and to calculate the amenity index of class I towns of the state of Maharashtra.

To achieve the sustainable development goal (Sustainable cities and communities), we have to control the growth of slum population and to combat the formation of slum; we have to analyze the situation of basic infrastructure provided in urban centers. Amenities and slum population has policy implications as to reduce the slum population, provide basic amenities to the households which will improve their standard of living and ultimately lead to reduction in growth of slum and check the future slum formation.

Elektronik yayıncılık 'belgelerin' elektronik ortamlar ve/ya da ağlar aracılığıyla dağıtımı, arşivlenmesi ve bu belgelere erişilmesi olarak tanımlanabilir. Elektronik posta 1960'ların ilk yarısında üniversitelerde kul­lanılmaya başlanmasına karşın, bilimsel iletişimde elektronik yayıncılığın kullanılması nispeten yeni bir gelişmedir. Bazı araştırmacılar çeşitli nedenlerle e-yayıncılığı ciddi bilimsel araştırma sonuçlarının yayımlanması için uygun bir ortam olarak görmemektedirler. Öte yandan yayıncılar da elektronik yayıncılıktaki ekonomik modeller tam olarak oluşmadan riske girerek pazarlarını sadece belirli bir teknolojiye sahip okuyucularla sınırlamak istememektedirler. Bunun yanı sıra elektronik yayıncılık ala­nındaki entellektüel mülkiyet hakları, arşivleme vb. gibi daha birçok sorun araştırmacılar, yayıncılar ve kütüphaneciler arasında yoğun tartışmalar yaratmaktadır. Bu makalede elektronik yayıncılıkla ilgili genel sorunlara kısaca değinilmekte, bu alandaki teknolojik, ekonomik ve arşivsel gelişmeler ile söz konusu gelişmelerin bilgi hizmetleri üzerindeki olası etkileri tartışılmaktadır.

Joined-up Library and Information Services in the University of the 21st Century
Authors: Hopkinson Alan
Published: November 2020

Universities in the UK at the start of the 21st century are in transition. Different trends are emerging in the subjects they teach and the way they are organized and student numbers are increasing. New and more powertul computer networks are being established. In this environment economies have to be made and administrative reorganisation can be seen to assist this. Libraries and computing services are increasingly overlapping in their coverage and are formally merging. Librarians are taking more part in training and the electronic library is changing much. Electronic journals, books and secondary services are changing the ways in which libraries work. The concept of the hybrid library has emerged and the virtual learning environment means that the traditional boundaries between classroom and library are blurring. A recent SCONUL report made some predictions about library economics, technological developments and student numbers.
