Highlights

Video processing technology was used to evaluate beef cattle temperament objectively.

Multiple beef cattle temperament methods were compared with video processing technology.

Potential automatic temperament evaluation systems could be developed based on our video processing method.

Abstract. Cattle temperament has potential impacts on growth, carcass characteristics, and meat quality. Both objective and subjective methods have been used to assess temperament, such as temperament score (TS), docility score (DS), flight speed (FS), and exposed eye white percentage (EW). Subjective methods for evaluating cattle temperament are labor-intensive and potentially stressful for the animals. Video technology (VT) has advantages of being noninvasive, automated and remotely operable, and compatible with cloud-based complex algorithms, which facilitates immediate field deployment of results. Because VT has not been reported as a beef cattle temperament evaluation method, the objectives of this study were to (1) verify the feasibility of VT as an evaluation method for beef cattle temperament, and (2) assess the accuracy and reliability of the VT measurements in comparison with TS and DS. A total of 170 calves were video recorded while they were in a squeeze chute; simultaneously, DS and TS measurements of the same calves were conducted. Maximum movement distance (MMD), average movement distance (AMD), and moving frequency (MF) were calculated according to the distances measured from the videos using an algorithm developed in this research. Pearson correlation coefficients among MMD, AMD, MF, TS, and DS were calculated and were 0.264 (p < 0.001) for DS versus TS, 0.438 (p < 0.001) for MF versus TS, 0.017 (p = 0.838) for AMD versus DS, 0.107 (p = 0.192) for AMD versus TS, 0.058 (p = 0.481) for MMD versus DS, and 0.077 (p = 0.350) for MMD versus TS. This study showed that MF could be a good indicator for assessing cattle temperament coupled with VT as a quantitative tool, requiring minimal equipment and thus providing an objective method for selecting cattle with appropriate temperaments.

Reconfigurable optical time delay array for 3D lidar scene projector
Authors: Gao Yanze , Zhang Sichen , Wang Xin , Shi Rui , Zhao Yuejin , Li Zhuo
Published: November 2020

3D lidar scene projector (LSP) plays an important role in the hardware-in-the-loop (HIL) simulation for autonomous driving system (ADS). It generates a simulated 3D lidar scene in laboratory by generating a 2D array of optical time delay signals. The reconfigurable optical time delay array (ROTDA) is crucial for LSP. However, current ROTDA solutions cannot support a LSP with a spatial resolution more than 10×10. In this paper, we proposed a novel ROTDA design based on the time slicing method. The optical signals with the same time delay but different spatial coordinates were treated as one time slice. Different time slices were superimposed into a composite image by a microlens-array-based imaging system to obtain a 3D lidar scene. And a spatial light modulator (SLM) was utilized to configure the time delay of each lidar scene pixel. We developed a ROTDA prototype with 64×64 pixels, each pixel can be reconfigured with up to 180 different time delays in one frame. The time delay resolution is 1 ns, the maximum time delay is 5000 s, and the 3D frame rate is 20Hz. The prototype can generate a continuous lidar scene with a distance span of 27 m, and can also generate up to 8 short scenes that are separated from each other along the lidar observation direction, each short scene covers a distance span of 3 m or 3.75 m. The design method proposed in this paper can also be applied to other occasions that demand a large number of time delay generators.
Performance studies of high-average-power picosecond optical parametric generation and amplification in MgO:PPLN at 80 MHz
Authors: Chaitanya Kumar S. , Nandy B. , Ebrahim-Zadeh M.
Published: November 2020

We report on performance studies of high-average-power single-pass picosecond optical parametric generation (OPG) and amplification (OPA) tunable near 2 µm in MgO:PPLN pumped by an Yb-fiber laser at 1.064 µm and 80 MHz pulse repetition rate. The simple setup based on two identical crystals, and without the need for an intermediate delay line for synchronization, delivers up to 6.3 W of average power at an overall conversion efficiency of ∼50% and is tunable across 1902–2415 nm. We present systematic characterization of OPG and OPA stages to compare their performance and investigate the effect of parametric generation in the high-gain limit, enabling high output power and full-width-half-maximum (FWHM) spectral bandwidths as large as 189 nm. The OPG-OPA output exhibits excellent passive power stability better than 0.3% rms and central wavelength stability better than 0.03% rms over 1 hour, in high spatial beam quality with M2<2. The OPG output pulses have duration of 5.2 ps with a FWHM spectral bandwidth of 117 nm at 2123 nm, resulting in a time-bandwidth product of ΔτΔν∼40, indicating ∼4 times temporal compression compared to the input pump pulses. Theoretical simulations confirm the effect of pump beam divergence on the observed shift in wavelength tuning with respect to temperature, while the exponential gain in the parametric process is identified as playing a key role in the resulting pulse compression.
Superposed constellation design for spatial multiplexing visible light communication systems
Authors: Le-Tran Manh , Kim Sunghwan
Published: November 2020

Superposed constellation for spatial multiplexing visible light communication (VLC) systems has recently attracted significant attention as a promising method to alleviate the effect of nonlinearity on light-emitting diodes (LEDs) that has achieved significant performance improvements in VLC systems. A large minimum Euclidean distance (ED) value of the superposed signals can be achieved at the receiver side by employing optimal power ratios transmitted from different LEDs. However, the power allocation strategy using fixed shaped sub-constellations at the LEDs has the inherent limitation of low optimization dimensions. In this paper, we propose optimizing the sub-constellations at individual LEDs instead of just the power allocation coefficients to further increase the minimum ED value. Moreover, intra-ED and inter-ED terms are used to reduce the complexity of the optimization solving process. The simulation results show that the proposed constellation design scheme can improve the symbol error rate performance compared to the conventional one, and the right choice of pre-defined shape of the sub-constellations at the LEDs has an important role in the optimization process.

Published: November 2020

In this Letter, we demonstrate the design and fabrication of a
biomimetic curved compound-eye camera (BCCEC) with a high resolution
for detecting distant moving objects purpose. In contrast to
previously reported compound-eye cameras, our BCCEC has two distinct
features. One is that the ommatidia of the compound eye are deployed
on a curved surface which makes a large field of view (FOV) possible.
The other is that each ommatidium has a relatively large optical
entrance and long focal length so that a distant object can be imaged.
To overcome the mismatch between the curved focal plane formed by the
curved compound eye and the planar focal plane of the CMOS image
sensor (CIS), an optical relay subsystem is introduced between the
compound eye and the CIS. As a result, a BCCEC with 127 ommatidia in
the compound eye is designed and fabricated to achieve a large FOV of
up to

. The experimental results show that
objects with a size of 100 mm can be clearly resolved at a distance of
25 m. The capture of the motion trajectories of a moving object is
also demonstrated, which makes it possible to detect and track the
moving targets in a huge FOV for security surveillance purposes.
Few-layer metamaterials for spontaneous emission enhancement
Authors: Li Ling , Zhou Zhangyu , Min Changjun , Yuan Xiaocong
Published: November 2020

Multilayer hyperbolic metamaterials consisting of alternating metal and dielectric layers have important applications in spontaneous emission enhancement. In contrast to the conventional choice of at least dozens of layers in multilayer structures to achieve tunable Purcell effect on quantum emitters, our numerical calculations reveal that multilayers with fewer layers and thinner layers would outperform in the Purcell effect. These discoveries are attributed to the negative contributions by an increasing layer number to the imaginary part of the reflection coefficient and the stronger coupling between surface plasmon polariton modes on a thinner metal layer. This work could provide fundamental insights and a practical guide for optimizing the local density of optical states enhancement functionality of layered metamaterials.

Authors: Anh Hien Ho , Tam Nguyen Minh , Tam Vo , Van Minh Huynh , Hoa Nguyen Phuong , Heytens Stefan , Derese Anselme , Devroey Dirk
Published: November 2020

Introduction

Cardiovascular disease (CVD) being the leading cause of the morbidity and mortality in Vietnam, the objective of this study was to estimate the total 10-year CVD risk among adults aged 40–69 years by utilizing World Health Organization/International Society of Hypertension (WHO/ISH) risk prediction charts in Central Vietnam.

Materials and methods

In this cross-sectional study, multi-staged sampling was used to select 938 participants from a general population aged from 40 to 69. The CVD risk factors were then collected throughout the interviews with a standardized questionnaire, anthropometric measurements and a blood test. The cardiovascular risk was calculated using the WHO/ISH risk prediction charts.

Results

According to the WHO/ISH charts, the proportion of moderate risk (10–20%) and high risk (>20%) among the surveyed participants were equal (5.1%). When “blood pressure of more than 160/100 mmHg” was applied, the proportion of moderate risk reduced to 2.3% while the high risk increased markedly to 12.8%. Those proportions were higher in men than in women (at 18.3% and 8.5% respectively, p-value <0.001, among the high-risk group), increasing with age. Male gender, smoking, ethnic minorities, hypertension and diabetes were associated with increased CVD risk.

Conclusions

There was a high burden of CVD risk in Central Vietnam as assessed with the WHO/ISH risk prediction charts, especially in men and among the ethnic minorities. The use of WHO/ISH charts provided a feasible and affordable screening tool in estimating the cardiovascular risk in primary care settings.
The influence of habitat use on harvest vulnerability of cow elk (Cervus canadensis)
Authors: Sergeyev Maksim , McMillan Brock R. , Hersey Kent R. , Larsen Randy T.
Published: November 2020

Pressure from hunting can alter the behavior and habitat selection of game species. During hunting periods, cervids such as elk (Cervus canadensis) typically select for areas further from roads and closer to tree cover, while altering the timing of their daily activities to avoid hunters. Our objective was to determine the habitat characteristics most influential in predicting harvest risk of elk. We captured 373 female elk between January 2015 and March 2017 in the Uinta-Wasatch-Cache National Forest and surrounding area of central Utah, USA. We determined habitat selection during the hunting season using a resource selection function (RSF) for 255 adult cow elk. Additionally, we used a generalized linear mixed model to evaluate risk of harvest based on habitat use within home ranges (3rd order selection) as well as the location of the home range on the landscape to evaluate vulnerability on a broader scale. Female elk selected for areas that reduced hunter access (rugged terrain, within tree cover, on private land). Age, elevation and distance to roads within a home range were most influential in predicting harvest risk (top model accounted for 36.2% of AIC weight). Elevation and distance to trees were most influential in predicting risk when evaluating the location of the home range (top model accounted for 42.1% of AIC weight). Vulnerability to harvest was associated with proximity to roads. Additionally, survival in our landscape decreased with age of femaleelk.

Authors: Kusumaningrum Dian , Saraswati Dewi Savitri , Seprianus Seprianus
Published: November 2020

The economy is shifting into the digital economy and to overcome it, the banking industry competes through innovation and digital strategy. Smartphone-based mobile banking is the key component of the digital strategy with 70% of the banks agree to focus their strategy on mass customer segment (PWC, 2017).

The purposes of the study are to identify the predicting factors influencing the intention to use mobile banking and empirically validate a model explaining the behavioral intention to use it, especially on the Bottom of Pyramid (BOP) segment. The model used was Structural Equation Model (SEM) based on Partial Least Square (PLS). The data used for developing the model was based on a survey to 100 BOP households.

The results of this study show that the variables that have the highest significant effect on BOP’s customer intention to use mobile banking are involuntary barriers, followed by perceived risk, and attitude. This result can be further used by researchers and mobile banking providers to evaluate the existing mobile banking services to improve its contribution in providing better market penetration and more appropriate financial services for BOP and ultimately financial inclusion in Indonesia.

Accumulation of Knowledge by Strategic Public Procurement through Public-Private Partnerships for Service Innovation in Japan
Authors: Suehiro Taeko , Miyazaki Kumiko
Published: November 2020

This study focuses on how governments strategically procure public service through Public–Private Partnership (PPP) – or more specifically, Private Finance Initiative (PFI) arrangements. PPP/PFI is recognised as a key element of demand-oriented innovation policy in the field of social infrastructure.  However, owing to the considerable uncertainty of each project, the benefits of PPP/PFI are subject to debate, as is the role of public procurement in fostering public service innovation. The purpose of this study is to examine how governments strategically procure public services from construction firms in Japan. We conduct a comparative case study of two waste-to-energy PFI projects to clarify how governments improved the public procurement.

The results suggest the following: first, municipalities utilise a greater extent of other municipalities’ experience through external experts (i.e. Ministry of Environment, advisors, committee members and potential bidders) and standardised service criteria. Second, the codification of tacit knowledge, which both public and private entities have gained from previous projects, is important for securing a robust and routinised service level and reaping the benefits of the scale of repetition. Third, interaction with private companies in the bidding process with an appropriate manner would foster public service innovation. Governments' capability development through the use of internal and external resources can create space for private companies to provide better service by accumulating tacit knowledge within the projects.

Published: November 2020

The pulp and paper industry has a great impact in the world. It has been manufactured for ages and ages, it is still booming up as industry in small scale and large scale levels. Despite the fact that they produce printing and writing papers, paper rolls, packaging material etc. they also produce large amount of waste materials from their Industry by Manufacturing. This when left untreated leads to environmental pollution, harsh contamination and so on. As every industry has its own waste water treatment methods to recycle, reuse and reduce pollution. This Industry also has its own criteria to carry out the process of waste water treatment, yet it lags in being efficient in it. By the sources collected and compared with other kinds of industries it is listed that pulp and paper manufacturing industry is one of the top most industries to produce large volumes of waste water which has degradable organics at higher level. Hence this paper aims to study the manufacturing process, waste water components released and its effect on environment, the treatment methods carried out and how it can be improvised efficiently in forthcoming days
The introduction of the European fallow deer to the northern provinces of the Roman Empire: a multi-proxy approach to the Herstal skeleton (Belgium)

Published: November 2020

Many exotic animal species were introduced to Northern Europe during the Roman period, including fallow deer (Dama dama). To date, however, finds of fallow deer bones at archaeological sites in this region have been sporadic and disarticulated, leaving uncertainty over their origins. This article presents the first known articulated fallow deer skeleton from Roman North-western Europe. Osteological, ancient DNA, radiocarbon dating and stable isotope analyses confirm that the species was established in this region by the Roman period, probably originating from translocated, rather than native, Mediterranean populations. Clarifying the origins of fallow deer in North-western Europe is critical for understanding the dynamics of species exchange around the Roman Empire.

Properties of cellulose nanofibril produced from wet ball milling after enzymatic treatment vs. mechanical grinding of bleached softwood kraft fibers
Authors: Zeng Jinsong , Liu Lu , Li Jinpeng , Dong Jiran , Cheng Zheng
Published: November 2020

Cellulose nanofibril (CNF) is a class of promising and renewable nanocellulosic material due to its unique dimensional characteristics and appealing properties. CNF preparations based on TEMPO pretreatment followed by high-pressure homogenization have been studied intensively, while the high energy consumption and the environmental issues remain challenges to their application. Mechanical refining processes have been commonly applied at the academic and industrial relevant scales for CNF production. In this study, bleached softwood kraft pulp was subjected to high-efficiency wet ball milling (following enzymatic pretreatment) and mechanical grinding to obtain CNF. The effects of ball milling time, grinding gap, and grinding passes on structure and properties of CNF were evaluated. Scanning electron microscopy images confirmed that the diameter of CNF was decreased with the increment of ball milling time and number of grinding passes. The results indicated that ball milling time, grinding gap, and grinding passes were important to increase the dispersity of CNF suspensions. The degree of polymerization and crystallinity index of CNF decreased with increasing ball milling time and grinding passes.

War mercenaries can be traced back to the ancient era and it still survives to this day, though its form and means of use have significantly changed in the second part of the 20th century in response to changes in international law. Numerous countries nowadays are employing these modern mercenaries to replace their soldiers in many military roles. Due to the rapid spread of private military companies (PMC) and the number of contracts granted to them every year, a major concern has been raised, and until this day there are no clear international law documents that regulate the activities and define the legal status of these military contractors. Because of this, the question of PMC’s is seemingly in a grey zone of law. The main aim of this paper is to examine the trends of PMC’s, and the existing efforts to properly regulate them both on international and national levels.

La presente lectura de los ensayos de Marius de Zayas, en torno a Estados Unidos y su cultura, busca caracterizar la presencia del kitsch y la extranjería como dos de las principales nociones que atraviesan los textos comprendidos bajo el título "La vida en Nueva York". Estos textos los encontramos recopilados en el libro Crónicas y ensayos: Nueva York y París, 1909-1911 del 2008.
El objeto de este análisis es profundizar en la mirada crítica del mexicano en torno al viaje, la cual se aparta de la fascinación del turista y pone de relieve una constante sensación de extrañamiento, de estar fuera de sitio en consonancia con el desencanto de la migración. Un segundo elemento a considerar es la tensión latente entre la admiración que estos ensayos reflejan en torno al portento industrial y la fastuosa arquitectura del país del norte, frente a las problemáticas que De Zayas atestigua en una cultura pragmática, utilitarista y mercantil. Finalmente, se interpreta que Marius de Zayas expone a través de sus textos una visión moderna que anticipa una sociedad del espectáculo, plagada de simulacros de éxito y entretenimiento evasivo.
Immunohistochemical study of IGF-I and IGF-II expression in canine mammary tumours: Prognostic and diagnostic role
Authors: Ozmen Ozlem
Published: November 2020

Mammary tumours are among the most common tumours in dogs and are of interest due to their similarities to human breast tumours. Insulin-like growth factors (IGFs) are considered important in cell growth and development. The aim of this study was to investigate the immunohistochemical expression of IGF-I and IGF-II in benign and malignant canine mammary tumours. In this study, 10 benign and 10 malignant mammary tumours from the archives of the Department of Pathology were used, and five normal breast tissues were used as controls. It was observed that the expression of IGF-I and IGF-II was low to absent in benign tumours and increased in malignant tumours. The expression of IGF-II was higher than that of IGF-I. This study showed that IGF-I and IGF-II can be used as criteria for malignancy in canine mammary tumours. The results also indicate that IGF-I and IGF-II may be used as early diagnostic markers, and their inhibition may be used for the treatment of canine and human mammary tumours in the future.

O estudo analisa a divulgação de notícias sobre C,TI dois maiores jornais impressos de Mato Grosso, o Diário de Cuiabá e A Gazeta, assim como sua contribuição para a visibilidade científica regional e o espaço destino às universidades públicas em atuação no estado. As análises objetivaram detectar tendências, recorrência temática, editoria em que configura fato científico, procedência do fato informativo, gênero jornalístico na construção da notícia, autor do relato e uso de determinadas fontes de informação nas matérias selecionadas. O método adotado para sistematização e análise de dados seguiu pressupostos da Análise de Conteúdo (Bardin, 2009). Dessa forma, as observações visam inferir sobre o enfoque e espaço dados a matérias sobre ciência e tecnologia, critérios de noticiabilidade e divulgação da pesquisa produzida no estado. As investigações apontam que essas IES públicas ainda não ocupam lugar relevante em tais veículos, o que pode ser justificado pela inadequação de canais de relacionamento, assim como, pela necessidade de uma política de divulgação científica.
Is there “too much finance” in central and eastern european countries?
Authors: Grabowski Wojciech , Maciejczyk-Bujnowicz Iwona
Published: November 2020

In this paper, the parameters of the growth regression, including different variables measuring the degree of financial development for the Central and Eastern European countries are estimated. Next, the optimal values of specific variables measuring the level of financial development are calculated. The results of the empirical investigation indicate that countries with more stable financial markets and institutions and greater access to them grew faster in the period 2001-2015. The results reflecting the impact of the financial deepening on economic growth are more ambiguous. In the pre-crisis period, the relationship between the depth of financial institutions and economic growth turned out to be insignificant. After 2007, countries with moderate values (about 60%) of this coefficient recorded higher rates of growth in real GDP. A U-shaped relationship between the depth of financial markets and economic growth was identified. However the optimal level of development of stock markets was much higher in 2001-2007 than after the Lehman Brothers bankruptcy

Authors: Oskouei Malektaj Maleki , Nikoomaram Hashem , Roodposhti Freydoon Rahnama
Published: November 2020

This study investigates management communications in annual general meetings (AGMs) from a narrative perspective. This study evaluates the effective elements of AGMs from the shareholder’s viewpoint. According to the theoretical framework, the authors developed a conceptual model and extracted the suggested narrative model for the first time. The shareholder’s perception was measured through a questionnaire survey containing three sections – narrative, audience, and narrator – with 32 indicators from 151 shareholders measuring shareholders’ opinions about AGMs in Iran. The results indicate that although shareholders do not consider the AGM communications made by management board as a narrative, they obtain relevant information with a logical flow in AGMs, and believe that these relations are useful. The characteristics of the management board impact on the persuasiveness of their communications. The results supported the mediating effect of AGM communication between managers and shareholders
Prices of accommodation rental as functioning on the basis of a sharing economy in the capitals of cee states
Authors: Mach Łukasz
Published: November 2020

Housing rental from private resources, thanks to the growing popularity of a sharing economy, is becoming more and more common. The principles of market activities compliant with the assumptions of a sharing economy create new frameworks in the science of economics, simultaneously subjecting classical methods and tools of management to verification. Making use of new information technologies and peer-to-peer technology, which as part of the former, has facilitated using a sharing economy in the hotel industry, creating a new community in the rental of housing market – people providing services of short-term renting of private accommodation facilities. The conducted research presents one-day rental (of the Bed & Breakfast type) functioning in compliance with the principles of a sharing economy. Its parametrization was carried out in the area of the formation of prices and their distribution. The resources of B&B rental were examined in the capital cities of Central and Eastern Europe. For each city the average prices of rental were determined, as were the average prices of extra services provided within the business activity (i.e. mean service charges and mean charges for cleaning). Additionally, a comparative analysis was carried out regarding the pricing of average rental costs with a simultaneous study of the significance of the differences observed in them. The conducted research allowed defining the structure of the total price of rental, which is composed of the price of the rental displayed on the webpage including offers of B&B rental and additional charges, i.e. the service and the cleaning fees. It follows from the conducted research, among others, that about one-third of the offered housing rental resources did not charge fees for cleaning and that the mean total price of housing rental for all the capitals of European the post-communist states ranged between 50 and 60 euros per night. From the point of view of the mean total rental price, the most expensive cities are Tallinn and Bratislava, whereas the cheapest countries are Bulgaria and Romania. The mean total rental prices for the capitals of Bulgaria and Romania are considerably lower than in the other capital cities of European post-communist states

Published: November 2020

This paper analyses the potential relation between IS reliability and organizational culture. Based on the literature review, the research gap is identified and hypotheses concerning the potential role of IS in shaping organizational culture are proposed. The community-oriented culture is suggested as a potential direction of culture reorganization. The hypotheses are verified based on the empirical research performed in 2017 in 400 organizations in Poland. The research results indeed confirmed that IS can be considered as one of the factors shaping organizational culture. However, the direction of its change appeared to be different than the one presented in the current literature

Authors: Külcü Özgür
Published: November 2020

Bu çalışma özellikle dijitalleştirme ve kurumsal içerik yönetimi uygulamalarının ardından belge yönetimi alanında yeni koşulları tanımlamayı amaçlamaktadır. Günümüzde dijitalleştirme ve içerik yönetimi iç içe gelişmektedir. Dijitalleştirme uygulamaları geleneksel olarak basılı ortamdan elektronik ortama geçişi temsil etse de yapılandırılmamış metin ya da imajların yarı yapılandırılmış ya da yapılandırılmış formlara dönüştürülmesi, tanımlanması ve erişimi faaliyetlerini de kapsamaktadır. Öte yandan kurumsal içerik yönetimi kurumsal bilgi içeriğin tümünün bütünsel olarak idaresini kapsamakta ve doküman yönetimi, belge yönetimi, Web içerik yönetimi ve iş akış yönetimi uygulamalarını içermektedir. Bu kapsamı ile dijitalleştirme ve içerik yönetim faaliyetleri belge yönetimi uygulamalarını yakından etkilemekte, alanın geleceğine yön vermektedir. Çalışma bu çerçevede gelişen süreci ve sonuçlarını değerlendirmektedir.

Authors: Karadeniz Şenol
Published: November 2020

Bu çalışmada Ankara’daki halk kütüphanelerinin, kullanıcılarını sunulan hizmetler hakkında neden yeterince bilgilendiremedikleri ve kendilerini kullanıcılarına neden yeterince tanıtamadıkları konusu irdelenmiştir. Araştırmanın amacı, halk kütüphanelerinde uygulanabilecek halkla ilişkiler yöntemlerinin neler olduğunu, halk kütüphanelerinin planlı halkla ilişkiler faaliyetlerinde bulunmamalarının nedenlerini ve bu nedenlerin boyutunu, özelliklerini ortaya koymaktır. Araştırmanın evrenini Ankara Büyükşehir Belediyesi sınırları içinde hizmet veren Kültür ve Turizm Bakanlığı’na bağlı halk ve çocuk kütüphaneleri oluşturmaktadır. Önceden yapılandırılmış görüşme kapsamında halk kütüphanesi yöneticileriyle görüşülmüş, ayrıca araştırma kapsamındaki kütüphanelerde gözlem tekniği uygulanmıştır. Araştırmadan elde edilen bulgular ışığında, halk kütüphanelerinin sistematik halkla ilişkiler programları uygulamamaları nedeniyle, kütüphaneyi tanıtmada ve sunulan hizmetlere ilişkin kullanıcılarda olumlu görüş oluşturmada yetersiz kaldıkları anlaşılmıştır.
Intelligent Information Retrieval Needs Smart Tools and Supporting Standards

Though Google is an eff ective and popular search engine for locating information on the World Wide Web, it has tended to have the eff ect of blinding people to the enormous and growing problem of accessing and sharing digital information, much of which is not even available on the Web. If we are to eff ectively tackle this problem we will need a range of information processing standards and tools. To illustrate this belief, brief mention is made of the new British Standards and emerging International Standards dealing with structured vocabularies and interoperability; and of some systems which are leading the way in their application and development.

Zaman ve mekân sınırları olmaksızın herkesin bilgi ile buluşabildiği kültür merkezleri haline gelen bilgi merkezlerinde, yeni hukuki ve etik sorumluluklar kapsamında bilgi güvenliğinin sağlanarak gerekli ve yeterli önlemlerin alınması; yakın gelecekte bilgi merkezlerinde meydana gelebilecek birçok maddi ve manevi zararın önüne geçilmesini sağlayacaktır.

Bu çalışmada, bilgi merkezlerinin ve bilgi profesyonellerinin elektronik bilgi güvenliğinin sağlanması ile ilgili hukuki ve etik sorumlulukları, Türk Hukuk Mevzuatı ve mesleki etik kuralları kapsamında ele alınmıştır. Bu bağlamda ilgili konulardaki teknik ve idari eksiklikler irdelenmiş ve literatüre dayalı hukuki ve etik sorumlulukların çelişen noktalarına dikkat çekilerek uygulanabilir çözümler üretilmeye çalışılmıştır. Çalışmada ayrıca; konu ile ilgili hukuk alanında ihtiyaç duyulan düzenlemeler üzerinde durulmuş ve hukuk kuralları ile çelişmeyen etik değerlerin belirlenmesinde dikkate alınması gereken konulara değinilerek önerilerde bulunulmuştur. Çalışma sonucunda, bilgi profesyonellerinin bilgi güvenliği ile ilgili olarak farkındalıklarının arttırılması ve bu konuda görevlerini yaparken yükümlü oldukları hukuk kuralları ve mesleki etik değerler hakkında bilinçlenmelerinin sağlanmasının önemi vurgulanmıştır.
Enterprise Content Management Implementation: An Overview of Phases, Standards and Best Practice Guidelines
Authors: Katuu Shadrack
Published: November 2020

The management of digital records has been a subject of numerous scholarly discussions for several years. Discussions on the application systems used to manage these records and other digital content have often used diff erent terminology, frequently interchangeably, with little regard to nuanced diff erences. In addition, a number of standards and best practice guidelines have been developed in diff erent countries to address the challenges of assessing and implementing these applications. While it may look like a lot of resources are available to records professionals as they tackle the challenges of implementing software applications, there is need to clarify terminology and identify implementation phases, as well, as the appropriate standards and best practice guidelines. This article, using primarily a review of literature, suggests definitional clarity and connectedness of diff erent terms used for Enterprise Content Management (ECM) applications. It identifies the various phases of implementation of ECM applications and off ers an overview of standards and best practice guidelines. Lastly it provides an assessment of the connection between phases of implementation in relation to standards and best practice guidelines, providing a gap analysis while also suggesting ways of addressing the variance.
Kullanıcı Odaklı Arşiv Hizmetlerinin Temel Unsurları – Araştırma Ortamı
Authors: Şentürk Burçak
Published: November 2020

Günümüzde hedef kitlesini anlayabilen, iş süreçlerine hedef kitlesinin ihtiyaç ve istekleri ile yön verebilen kurumların başarıyı yakalayabilecekleri öngörülmektedir. Çünkü hizmet verdiği sektör ne olursa olsun her kurum aslında yaptığı işleri hedef kitlesi için yapmaktadır. Bununla beraber kurumun sunduğu ürün ve hizmetler ile ilgili olarak son kararı da insan vermektedir. Bu noktada atılması gereken ilk adımlardan biri kurumlarda insan odaklılığı sağlayabilecek temel unsurların belirlenmesi ve bu temel unsurlar doğrultusunda hareket edilmesidir. Bilgi sunan kurumlar olarak arşivler de iş süreçlerinde kullanıcı odaklılığına önem vermelidirler ve arşivlerde de kullanıcı odaklılığı sağlayabilecek temel unsurlar belirlenmelidir. Bu bağlamda bu çalışmada kullanıcı odaklı arşivlerin temel unsurlarından biri olarak belirlenen “araştırma ortamı” üzerinde durulmaktadır ve kullanıcı odaklı bir araştırma ortamının sahip olması gereken temel özellikler ortaya konulmaktadır.
