Knowledge and Skills Competencies for Humanities Librarians Supporting Postgraduate Students
Authors: Johnson Glynnis , Raju Jaya
Published: December 2018

This paper reports on an aspect of a 2016 masters study which addresses the research question: what knowledge and skills do humanities librarians require to effectively provide support to postgraduate students in the digital age? The study adopted a qualitative approach using a multiple case study design, within a constructivist paradigm, to respond to the research question, with core competency theory used to provide theoretical support. Data were collected via semi-structured interviews and focus group discussions with purposively sampled librarians and postgraduate students from Stellenbosch University, the University of Cape Town and the University of the Western Cape, all of which are situated in the Western Cape of South Africa. A significant finding of the study is that a mixture of discipline-specific knowledge and skills, generic skills and personal attributes are required by humanities librarians to effectively support postgraduate students, especially in the current digital age. The study presents a knowledge and skills framework that could be used to ascertain humanities librarians’ current knowledge and skills as well as establish areas for further knowledge and skills acquisition.
From Divergence to Convergence in Hungarian Librarianship: Towards a Common Digital Platform
Authors: Kiszl Péter , Radó Rita , Hubay Miklós Péter
Published: December 2018

Hungarian librarianship and related research are sadly underrepresented in international literature. With this article we intend to fill this gap and inform the experts of library and information science of some of the most recent Hungarian innovations. After showcasing the international professional connections of Hungarian librarianship, we present the structure of the Hungarian public library network and its mode of operation. We also analyse current and future main digital development plans, projects and the most important related professional activities of Hungarian libraries. Emphasis is placed on information systems promoting cooperation between libraries and the issues of the National Library System Project, which is a large-scale modernisation programme carried out between 2016 and 2018, designed to develop the IT system of the National Széchényi Library. After introducing the information systems of academic and specialised libraries and the access models of scientific databases provided by multinational and Hungarian content services, we also discuss the endeavours of public libraries aiming for multifunctionality and community organisation. The paper ends by providing insights into how the outcomes of the recent initiatives have been fed back into Hungarian LIS training courses offered in higher education.

Authors: Ashiq Murtaza , Ur Rehman Shafiq , Batool Syeda Hina
Published: December 2018

The purpose of this study was to explore the perceptions of academic library leaders of Pakistan about library leadership. Qualitative research design was used with phenomenology approach as the present study aims to investigate what library leaders commonly perceive to be challenges, fundamental difficulties and needed skills to be successful. Data were collected through in-depth interviews from 15 senior academic library leaders. Major challenges found were identity crises followed by communication issues, financial constraints, CPD and administrative issues. The most challenging aspects of being an academic library leader were identified as trying to create awareness, lack of self-development culture and technological issues. The required leadership skills were communication, vision, social interaction, team building, organisational understanding and knowledge sharing. The findings of the study are helpful for current, young and future chief librarians to understand the challenges they may face and to develop the leadership skills needed to cope with these challenges. The study will also be helpful to academic institutions during their recruitment processes; professional associations for training purposes; and library schools for arranging and offering leadership courses.
The Trends of Media Coverage about Libraries in Korea: Using Semantic Network Analysis of Portal News
Authors: Cho Jane
Published: December 2018

The purpose of this study is to understand the trends and problems of media coverage about Korean libraries by selecting keywords from Korean portal news articles and conducting semantic network analysis. As a result, Korean news reports focus on public libraries rather than school and university libraries. Elsewhere, libraries’ lifelong learning program performance, such as cultural events and educational lectures, are overly biased on press release. In addition, news articles in all kinds of libraries are dominated by simple publicity about businesses or events rather than policy issues about library laws, budgets and manpower. Korea’s libraries reflected in the media are analyzed as cultural and social educational institutions rather than knowledge information centers.
A new Pb(II)-based coordination polymer constructed from a semirigid tricarboxylate ligand: crystal structure and anti-lung cancer activity
Authors: Yang Kun-Ning , Yuan Ke-De , Jiang Li-Li , Zhang Yong
Published: December 2018

Based on a semirigid tricarboxylate ligand 5-((4-carboxyphenoxy)methyl)benzene-1,3-dioic acid (H3L), a new Pb(II)-based coordination polymer formulated as [Pb(HL)(H2O)](H2O) (1) was synthesized under solvothermal conditions and characterized by single-crystal X-ray structural analysis, power X-ray diffraction, and elemental analysis. Compound 1 is a two-dimensional layered structure formed by the connection of the one-dimensional Pb(II)-based secondary building unit chains with the partly deprotonated HL ligands, which are further extended into three-dimensional supermolecular structures through the H-bonds. Furthermore, the size of the as-prepared 1 could be downsized into the nano region through a simple ultrasonic method. Finally, the antilung cancer activities of 1 and the nanosized 1 have been probed via the MTT assay against three human lung cancer cell lines (A549, H1299, and PC9).
Health Disparities for Immigrants: Theory and Evidence from Canada
Authors: Lebihan Laetitia , Olivier Mao Takongmo Charles , McKellips Fanny
Published: December 2018

Few empirical studies have been conducted to analyse the disparities in health variables affecting immigrants in a given country. To our knowledge, no theoretical analysis has been conducted to explain health disparities for immigrants between regions in the same country that differs in term of languages spoken and income. In this paper, we use the Canadian Community Health Survey (CCHS) to compare multiple health measures among immigrants in Quebec, immigrants in the rest of Canada and Canadian-born individuals. We propose a simple structural model and conduct an empirical analysis in order to assess possible channels that can explain the health disparities for immigrants between two regions of the same country. Our results show that well-being and health indicators worsen significantly for immigrants in Quebec, compared to their counterparts in the rest of Canada and Canadian-born individuals. Additional econometric analysis also shows that life satisfaction is statistically and significantly associated with health outcomes. The proposed structural model predicts that, when the decision to migrate to a particular area is based on income alone, and if the fixed costs associated with the language barrier are large, immigrants may face health issues.
The Contribution of Large Banking Institutions to Systemic Risk: What Do We Know? A Literature Review
Authors: Moch Nils
Published: December 2018

Against the background of the global financial crisis, we review recent literature on the debate about “too big to fail”. This is (still) one of the key issues in banking literature since it determines the conditions for adequate banking regulation, financial stability and economic welfare. Analyzing 30 papers from 2009 to 2017, our work focusses on the impact of large banks on systemic risk. Large financial institutions can affect systemic risk by either contributing to systemic risk or being extremely exposed to sources of systematic risk and contagion. We find a considerable number of theoretical and empirical studies providing evidence that against the background of the constitution of present-day real financial systems, bank size is a key predictor for systemic risk and that the largest banks disproportionately contribute to overall risk. This relationship is found in samples of different composition, for various periods and with different measures covering diverse aspects of systemic risk.
Care for the Elderly in Ur III Times: Some New Insights
Authors: Steinkeller Piotr
Published: December 2018

This communication studies the Ur III worker-designations ab(-ba)-il2, ama-il2, and (nu-mu-)su-il2, which appear in the economic sources from Umma and Girsu/Lagaš. Expending on the earlier treatments by C. Wilcke and W. Sallaberger, it is argued that these classifications designate workers who were temporarily freed from the performance of corvée duty, in order to be able to care for their elderly (and probably ailing) mothers and fathers. The existence of such regulations has important implications for the status of the Ur III labor.
Address Behaviour in Eight Unpublished ana bēlīja Letters from the Late Old Babylonian Ur-Utu Archive: Close Relatives Through a Distant Mirror?
Authors: Janssen Caroline
Published: December 2018

One of the common forms of address, in Old Babylonian letters, is ‘to my lord’ (ana bēlīja). If letters come from clandestine digs, it is hard to know who is hiding behind this title. In the context of the Ur-Utu archive, there is one unknown variable less. The addressee is the archive’s owner. It occurred to me that in eight ana bēlīja letters from this collection, the senders bore names identical to those of Inanna-mansum’s sons (Ur-Utu, Kubburum, Ilī-iqīšam and Ḫuzālum) and Ur-Utu’s wife Rā’imtum. Can it be confirmed that the sender and the correspondent of these letters are indeed close relatives, and that the ana bēlīja format was used to address a father, brother or spouse? If so, what does this practice tell us about the address ‘my lord’, as a social habit?
A Previously Unrecognized Version of Esarhaddon’s ‘Annals’
Authors: Novotny Jamie
Published: December 2018

This paper provides evidence for the existence of a new inscription of Esarhaddon from Nineveh: A 16926, a piece now in the Oriental Institute (University of Chicago), is not an exemplar of Nineveh B, but rather part of an edition of Esarhaddon’s ‘annals’ from Nineveh that was composed before Esarhaddon’s 5th year (676). The paper will also present evidence for reassigning 83-1-18,601, a small fragment in the British Museum, as an exemplar of Nineveh C or an early copy of Nineveh A.

Nicholas, JC, McDonald, KA, Peeling, P, Jackson, B, Dimmock, JA, Alderson, JA, and Donnelly, CJ. Pole dancing for fitness: The physiological and metabolic demand of a 60-minute class. J Strength Cond Res 33(10): 2704–2710, 2019—Little is understood about the acute physiological or metabolic demand of pole dancing classes. As such, the aims of this study were to quantify the demands of a standardized recreational pole dancing class, classifying outcomes according to American College of Sports Medicine (ACSM) exercise-intensity guidelines, and to explore differences in physiological and metabolic measures between skill- and routine-based class components. Fourteen advanced-level amateur female pole dancers completed three 60-minute standardized pole dancing classes. In one class, participants were fitted with a portable metabolic analysis unit. Overall, classes were performed at a mean Vo
2 of 16.0 ml·kg−1·min−1, total energy cost (EC) of 281.6 kcal (4.7 kcal·min−1), metabolic equivalent (METs) of 4.6, heart rate of 131 b·min−1, rate of perceived exertion (RPE) of 6.3/10, and blood lactate of 3.1 mM. When comparing skill- and routine-based components of the class, EC per minute (4.4 vs. 5.3 kcal·min−1), peak Vo
2 (21.5 vs. 29.6 ml·kg−1·min−1), METs (4.3 vs. 5.2), and RPE (7.2 vs. 8.4) were all greater in the routine-based component (p < 0.01), indicating that classes with an increased focus on routine-based training, as compared to skill-based training, may benefit those seeking to exercise at a higher intensity level, resulting in greater caloric expenditure. In accordance with ASCM guidelines, an advanced-level 60-minute pole dancing class can be classified as a moderate-intensity cardiorespiratory exercise; when completed for ≥30 minutes, ≥5 days per week (total ≥150 minutes) satisfies the recommended level of exercise for improved health and cardiorespiratory fitness.

Conrado de Freitas, M, Rossi, FE, Colognesi, LA, de Oliveira, JVNS, Zanchi, NE, Lira, FS, Cholewa, JM, and Gobbo, LA. Postactivation potentiation improves acute resistance exercise performance and muscular force in trained men. J Strength Cond Res 35(5): 1357–1363, 2021—The purpose of this study was to investigate the effects of heavy back squat (90% one repetition maximum [1RM]) postactivation potentiation (PAP) on acute resistance exercise performance and force production in recreationally trained men, and to verify the relationship between maximal strength and the PAP response. Ten resistance-trained men randomly completed 4 experimental trials: (a) back squats without PAP (No-PAP), (b) back squats with PAP, (c) maximum voluntary isometric contraction (MVIC) of the quadriceps without PAP, and (d) MVIC with PAP. Back squats were performed with 4 sets at 70% of 1 RM with 2 minutes of rest interval. The number of squats repetitions performed was recorded for each set, and a total number of repetitions were calculated to analyze performance. Maximum voluntary isometric contraction was measured using electronic dynamometer, and the peak force and mean force were recorded. Blood lactate concentration was analyzed presquat and postsquat exercise. Repetitions performed in the first set was significantly (p < 0.001) greater in the PAP condition (22.00 ± 5.14) compared with No-PAP (15.50 ± 5.10), which resulted in significantly (p = 0.001) more total repetitions performed in the PAP (56.20 ± 17.3) condition compared with No-PAP (48.80 ± 14.5). Maximum voluntary isometric contraction peak was higher in PAP than in No-PAP (PAP = 765.7 ± 147.8 vs. No-PAP = 696.8 ± 131.5 N, p = 0.006). No significant correlations were observed between back squat 1RM relative to body mass and the PAP response in squat and MVIC. There were no significant differences in lactate concentration between conditions. In conclusion, PAP resulting from a heavy load prior back squat exercise improved total volume during resistance exercise. In addition, PAP was effective to increase force production during MVIC, but there was no relationship between relative 1RM values and the PAP response in trained men.

Published: December 2018

The aluminum alloy AA6061 with 0.004, 0.008, 0.012, and 0.016 volume fractions of silicon carbide (SiCp) nanocomposites were fabricated using a semi-solid stirring assisted ultrasonic cavitation technique. Specimens are tested for morphology, density, mechanical, and wear properties. The density, strength, and microhardness of the nanocomposites increased with the increase of SiCp nano-reinforcement particles in the matrix. The yield strength of the SiCp-reinforced nanocomposites was evaluated by considering various strengthening mechanisms. It is found that the yield strength of the nanocomposites increased by 96 % for 0.004, 172 % for 0.008, 158 % for 0.012, and 206 % for 0.016 volume fractions of SiCp compared to the base alloy. The dislocation mismatch effect and Orowan strengthening effect are found to play a significant role in the SiCp-reinforced AA6061 nanocomposites. The dislocation mismatch effect increased with the reinforcement particles’ size reduction in the matrix. The Orowan strengthening effect increased up to 1.56 nm critical size of SiCp, and above that it decreased slightly. The experimental results are compared to predicted results obtained from various analytical models. The experimental results are observed to be in close agreement with the Mirza and Chen model. The wear loss of nanocomposites decreased with an increase in the nano-sized SiCp reinforcement quantity in the matrix. The amount of 0.004, 0.008, 0.012, and 0.016 volume fractions of nano-sized SiCp reinforcement additions to the AA6061 alloy matrix decreases the wear coefficient by 19.23 %, 38.46 %, 57.69 %, and 62.69 %, respectively. The worn surfaces were also analyzed using a scanning electron microscope and energy-dispersive X-rays.

Authors: Tseng Kuo-Hsiung , Hsieh Chin-Liang , Chung Meng-Yun , Wu Chang-Ji
Published: December 2018

This study used the arc discharge generated by an electrical discharge machine to melt metal silver into nano-sized particles. The manufacturing process was free from chemical agents, while only deionized water was used as the dielectric fluid. The process parameters and discharge pulse width were set to prepare silver nanoparticles suspended in the dielectric fluid, and the process was simple and rapid. However, the process parameters were closely related to success in the discharge. Among them, the discharge pulse width had the most significant effect. Therefore, this study developed a successful arcing rate measuring unit and discussed the effect of different process parameters on the success rate of preparing nano-silver colloid. Silver with a purity of 99.9 % was selected as the main research subject. The results showed that under the same process parameters, the arcing rate is not an exact value but a range value, and the 30 μs-30 μs discharge pulse width is identical as the optimum process parameter. When preparing the nano-silver colloid, the higher the processing efficiency, the shorter the diameter of the particle.

Published: December 2018

An experiment was conducted to study the strain rate sensitivity of yield behavior in an amorphous polymer, poly(methyl methacrylate) (PMMA). Compression, tension, shear, and combined shear-compression tests were conducted at four different loading rates. Experimental results indicate that strain rates had a pronounced effect on the yield behaviors of PMMA. Therefore, a strain rate–dependent yield function was developed, and the influences of hydrostatic pressure and strain rate on yield were analyzed. Based on the detailed discussion of the three material constants of the yield criterion, the influence of hydrostatic pressure on the tension and compression asymmetry was analyzed. A modified Johnson-Cook model was introduced to determine the effect of strain rate hardening on flow stress. The results of a compression test were described well by this mode. The change in the trend of parameter C of the mode (which characterizes the effect of strain rate) was also analyzed under the conditions of quasi-static loading.
Testing and Evaluation of Linear Shear Mode Magnetorheological (MR) Damper Based on Rheological Properties of MR Fluid
Authors: Patel Dipal M. , Upadhyay Ramesh V.
Published: December 2018

Magnetorheological (MR) fluid exhibits variable yield stress and viscosity with the magnetic field, which is why it is classified under smart materials. Because of its controllable properties, MR fluid has many applications. The most common application of MR fluid is MR fluid damper. According to the flow of MR fluid, three types of dampers are possible; flow mode, squeeze mode, and shear mode. In this article, rheological properties of MR fluid, which has a high Bingham number (ratio of MR force on-state to off-state), are synthesized and the MR properties are studied. Based on these properties, a linear shear mode MR damper is designed and evaluated for its performance. A unique model is adopted to evaluate the performance of MR damper. In this model, the dimensionless Mason number is applied to establish the relation between test data of damper and rheological properties of MR fluid. This is verified for two different volume fractions of magnetic particles in MR fluid.

Published: December 2018

This work aims to investigate the effect of the addition of water to corn oil biodiesel (BD) (COBD) in a diesel engine to view its effect on performance and emission characteristics. Two fuel samples were prepared using a novel surfactant Span 80 (MilliporeSigma, Burlington, MA), with different concentrations (94 % corn oil + 4 % water + 2 % Span 80 (COBDE1) and 90 % corn oil + 8 % water + 2 % Span 80 (COBDE2)). Experimental results showed that the water samples of COBD had higher brake thermal efficiency and lower brake-specific fuel consumption than that of neat COBD at all engine brake power. In addition, smoke and nitrogen oxide emissions are reduced by 4–11 % and 6–10 % using corn oil–water samples compared to neat COBD. Furthermore, the introduction of COBD-water emulsions in a diesel engine reduces the unburned hydrocarbon and carbon monoxide emissions considerably.
Understanding Soil Surface Water Content Using Light Reflection Theory: A Novel Color Analysis Technique Considering Variability in Light Intensity

Published: December 2018

Accurate measurement of soil surface water content is vital for analyzing evaporation, partition of solar radiation, infiltration, and runoff. Color analysis of soil has already been found to be a nonintrusive, economical, and feasible approach for the measurement of surface water content. However, color contrast within the soil domain was rarely considered in color analysis approaches demonstrated by previous researchers. This color contrast occurs because of the spatial heterogeneity of light intensity in the soil domain. This study aims to demonstrate and validate a new color analysis technique for overcoming the shortcomings of previous approaches. Six series of tests were conducted to analyze the color of red soil at various surface water contents. In addition, six measured dry densities on the compaction curve were selected for validation of the proposed color analysis technique. Soil has been compacted by hand to the desired state of compaction in a small mold. Images of soil samples were captured using a commercially available camera model (NIKON COOLPIX L29, Nikon, Tokyo, Japan). The brightness variation of soil samples was quantified using the change in mean gray value of the images. A white paper was placed below the mold to consider color contrast within the soil samples. Mean gray values of all test samples were obtained using a public domain image processing program called ImageJ. Color contrast within the soil samples was equalized with respect to reference locations considered on the white paper. Mean gray value was found to decrease with the increase in surface water content. Decrement in mean gray value was found to be more significant (i.e., 14–27 %) in saturation and desaturation zones of soil water characteristic curves (SWCCs) as compared to that in the residual zone (i.e., 3–9 %) with a 3–4 % increase in surface water content. A correlation between mean gray value and surface water content was established for the red soil.

Published: December 2018

Vegetable oils are currently used for biodegradable and renewable base stocks for quenchant formulation. However, there are relatively few references relating to their true equivalency, or lack thereof, comparative to the quenching performance of petroleum oil-based quenchant formulations. To obtain an overview of the variability vegetable oil quenching performance, the cooling curves and rewetting properties were determined, and the surface heat flux properties were calculated. The vegetable oils that were studied included canola, coconut, corn, cottonseed, palm, peanut, soybean, and sunflower oils. Cooling curves were obtained using the Tensi multiple-surface thermocouple 15 mm diameter by 45 mm cylindrical Inconel 600 probe (Note: The multiple thermocouple probe was custom manufactured to conform to a drawing provided by: Heattec located at Seglaregatan 1C, 302 90 Halmstad, Sweden). For comparison, similar data was obtained with Houghto-Quench H100, a conventional (slow) petroleum quenchant oil, and Houghto-Quench HKM, an accelerated (fast) petroleum oil quenchant (Houghton International Inc., Valley Forge, PA). The results of this work will be discussed here.
Anterior Insular Cortex is Critical for the Propensity to Relapse Following Punishment-Imposed Abstinence of Alcohol Seeking

Published: December 2018

Humans with alcohol use disorder typically abstain because of the negative consequences associated with excessive drinking, and exposure to contexts previously associated with alcohol use can trigger relapse. We used a rat model that captures a characteristic of this human condition: namely voluntary abstinence from alcohol use because of contingent punishment. There is substantial variability in the propensity to relapse following extended periods of abstinence, and this is a critical feature preventing the successful treatment of alcohol use disorder. Here we examined relapse following acute or prolonged abstinence. In male alcohol preferring P rats, we found an increased propensity to relapse in Context B, the punishment context after prolonged abstinence. Next, we found that neither alcohol intake history nor the motivational strength of alcohol predicted the propensity to relapse. We next examined the putative circuitry of context-induced relapse to alcohol seeking following prolonged abstinence using Fos as a marker of neuronal activation. The anterior insular cortex (AI) was the only brain region examined where Fos expression correlated with alcohol seeking behavior in Context B after prolonged abstinence. Finally, we used local infusion of GABAAand GABABreceptor agonists (muscimol + baclofen) to show a causal role of the AI in context-induced relapse in Context B, the punishment context after prolonged abstinence. Our results show that there is substantial individual variability in the propensity to relapse in the punishment-associated context after prolonged abstinence, and this is mediated by activity in the AI.

SIGNIFICANCE STATEMENTA key feature of alcohol use disorder is that sufferers show an enduring propensity to relapse throughout their lifetime. Relapse typically occurs despite the knowledge of adverse consequences including health complications or relationship breakdowns. Here we use a recently developed rodent model that recapitulates this behavior. After an extended period of abstinence, relapse propensity is markedly increased in the “adverse consequence” environment, akin to humans with alcohol use disorder relapsing in the face of adversity. From a circuitry perspective, we demonstrate a causal role of the anterior insular cortex in relapse to alcohol seeking after extended abstinence following punishment imposed voluntary cessation of alcohol use.
THE INFLUENCE OF CHITOSAN FLAKE DEACETYLATION DEGREE ON ORTHOPHOSPHATE SORPTION EFFICIENCY FROM AQUEOUS SOLUTIONS
Authors: Bugajska Paula , Filipkowska Urszula , Jóźwiak Tomasz , Kuczajowska-Zadrożna Małgorzata
Published: December 2018

The article presents the effectiveness of orthophosphate sorption from aqueous solutions depending on the deacetylation degree of chitosan flakes.
The first stage of the research was to determine the pH value at which the sorption process was the most effective (from the pH range 2–11). In the second stage, research was carried out to determine the maximum sorption capacities of chitosan with deacetylation degrees of 75%, 85% and 90% in relation to PO43-. The highest effectiveness of orthophosphate removal on chitosan, regardless of its deacetylation degree, was obtained at pH 4. At pH 2 and 3, the chitosan flakes dissolved. This study showed that the sorption effectiveness of phosphorus compounds depends on the deacetylation degree of chitosan. Along with the increase in deacetylation degree, the sorption capacity of chitosan also increases in relation to orthophosphates. It is related to the higher number of amino groups in the structure of chitosan, which are responsible for the sorption of pollutants in the form of anions. The maximum sorption capacity of chitosan-DD = 75% in relation to biogen was 5.13 mg/g, chitosan-DD = 85% was 5.65 mg/g, and chitosan-DD = 90% was 5.91 mg/g.
After 60 minutes, the desorption process had begun and was most likely caused by an increase in the pH of the solution. Due to chitosan's ability to neutralise the sample and the associated risk of desorption, the time of sorbent contact with sewage cannot be longer than 60 minutes.

Published: December 2018

Chitosan is a highly versatile biopolymer characterised by low toxicity, biocompatibility, and slow but complete biodegradation in the human body, possessing multiple reactive groups. One of the most well-known properties of positively charged chitosan derivatives is their ability to bind mucous membranes. The aim of this work was the analysis of mucoadhesion of unmodified 20 kDa chitosan and its hydrophobic (HC) and hydrophobic quaternised (QHC) derivatives in vitro and ex vivo. Unmodified chitosan formed large aggregates in vitro in keratinocyte and colon cell cultures and ex vivo in murine small intestine and muscle explants. At the same time, HC and especially QHC bound cells in vitro and ex vivo in a fine dotted manner, as evidenced by confocal microscopy. Such a pattern of hydrophobic derivatives distribution provides the possibility to develop mucoadhesive drug delivery systems with increased local drug release and improved chitosan biodegradation.

There are lots of studies conducted in Karabuk province, one of the most important iron-steel manufacturing center in Turkey, and the developing iron-steel sector in this province. However, the privatization of the national iron-steel factory, KARDEMIR, the establishment of Karabuk University and the like, have been causing rapid mental transformations which activate the transformations in iron-steel sector. Especially, the training programs for workers which have been practiced in Karabuk University and The Institute of Iron and Steel founded in Karabuk University indicate that this ongoing transforming process would continue rapidly and favorably. As a result, renewing the studies about the iron-steel sector in Karabuk periodically is a must. In this article, the socio-economic conditions of workers employed in iron-steel sector, their work satisfactions, their visions about iron-steel sector and the like varieties are examined empirically.

Published: December 2018

As being one of the prominent phenomenon in ecology, engineering and pyschology studies for more than thirty years, resilience has started to gain attraction and attention in management and organization fields in the last decade. The concept is accepted as an antidote of invulnerability (Weick, 1993), adaptive functioning against risk hazards (Rutter, 1987) and ability to cope with multiple changes (Boyd and Folke, 2012). Resilience is either defined as set of available and accessible behaviors over time that reflects growth (Ungar; 2010,2011) or as the maintenance of positive adjustment under challenging conditions (Vogus and Sutcliffe, 2007),  it fosters the strenght and the survival of the organism. Resilience could be accepted in its infancy in management and organization studies, however, it has a grand potential to understand how employees in organizations endure ongoing changes, challenges and uncertainty that reveal through innovation and its potential effects on innovation performance. Due to lack of any measurement scale in employee innovation resilience, in this study,,we aim at proposing a model that presents innovation resilience as a second order multidimensional construct that consists of three dimensions and three sub-dimensions of each observable variables.

In this study, an integrated cash requirement forecasting and cash inventory optimization model is implemented in both the branch and automated teller machine (ATM) networks of a mid-sized bank in Turkey to optimize the bank’s cash supply chain. The implemented model’s objective is to minimize the idle cash levels at both branches and ATMs without decreasing the customer service level (CSL) by providing the correct amount of cash at the correct location and time. To the best of our knowledge, the model is the first integrated model in the literature to be applied to both ATMs and branches simultaneously. The results demonstrated that the integrated model dramatically decreased the idle cash levels at both branches and ATMs without degrading the availability of cash and hence customer satisfaction. An in-depth analysis of the results also indicated that the results were more remarkable for branches. The results also demonstrated that the utilization of various seasonal indices plays a very critical role in the forecasting of cash requirements for a bank. Another unique feature of the study is that the model is the first to include the recycling feature of ATMs. The results demonstrated that as a result of the inclusion of the deliberate seasonal indices in the forecasting model, the integrated cash optimization models can be used to estimate the cash requirements of recycling ATMs.

Kurumların performanslarının her geçen gün katlanarak artması, üst düzey yöneticilerin sahip oldukları liderlik rolleri ve uygulanan insan kaynakları politikaları neticesinde belli olmaktadır. Kurumlarda çalışanların yaşadıkları memnuniyetsizlikler, liderlerin çalışanlar üzerindeki tutum ve davranışları, aynı zamanda kurumların ömürlerini de belirlemektedir. Kurumlarda yaşanan iş devir oranındaki artış aynı zamanda kurumun performansında düşüşe sebep olabilmekte, maliyet unsurunu ortaya çıkarabilmekte, çalışanlara verilen eğitimlerin sonuçsuz kalmasına sebep olabilmektedir. Yapılacak çalışmalar sayesinde, kurumlarda üst düzey yöneticilerin alacakları kararlarda ve liderlik rollerinin ortaya konmasına katkıda bulunulması önem arz etmektedir. Çalışmanın örneklem kitlesini İç Anadolu bölgesinde bulunan özel ve kamu sektöründeki 323 beyaz yakalılar oluşturmaktadır. Elde edilen bulgular IBM SPSS 23 programında faktör ve güvenirlilik analizleri yapıldıktan sonra regresyon analizleriyle hipotezler test edilip analizleri yapılarak değerlendirilmiştir.

Türkiye için tarım sektörü dış ticaretin ve ekonomik kalkınmanın önemli bir parçasıdır. Bugün, dünya konjonktüründe özellikle tarım sektöründe Türkiye birçok tarımsal gıda ürünlerin üreticisi ve aynı zamanda ihracatçısıdır. Bu çalışmada Türkiye’nin tarım sektörünün ayrıntılı bir şekilde 24 fasıla göre karşılaştırmalı üstünlüğünün olup olmadığı analiz edilmiştir. Çalışmada Açıklanmış Karşılaştırmalı Üstünlükler (AKÜ), Açıklanmış Simetrik Karşılaştırmalı Üstünlükler (ASKÜ), Ticaret Dengesi İndeksinden (TDİ) yararlanılmış ve tarım sektörünün ürün haritası oluşturulmuştur. Analizde kullanılan veriler 2001-2017 dönemine ait Uluslararası Ticaret Merkezi’nden (INTRACEN) sağlanmıştır. Hesaplanan AKÜ ve ASKÜ sonuçlarına göre tarım potansiyeli yüksek olan Türkiye’nin 24 fasıldan 12’sinde karşılaştırmalı üstünlüğe, 11’inde rekabet gücüne sahiptir. Ayrıca Ticaret Dengesi İndeks (TDİ) değerlerine göre Türkiye 18 fasılda da net ihracatçı ülke konumundadır. Tarım sektörü ürün haritasına göre ise 24 fasıllın 9 unda 2001 yılından bugüne kadar Türkiye, dünya ihracatında söz sahibidir. Fasıl sayılarına göre Türkiye tarım sektöründeki karşılaştırmalı üstünlük oranı %50, rekabet gücü oranı %46 ve net ihracat gücü oranı ise %75’dir.
TÜRKİYE’DE BANKA SERMAYE TAMPONLARI, KREDİ BÜYÜMESİ VE İŞ ÇEVRİMLERİ

Bu çalışmada, Türkiye’de faaliyet gösteren bankaların sermaye tamponlarının iş çevrimleri ve kredi büyümesi ile ilişkisi 2002-2017 dönemi için üç aylık veriler kullanılarak incelenmiştir. Tahminler sistem genelleştirilmiş momentler metodu kullanılarak yapılmış ve söz konusu etkilerin bankaların faaliyet türlerine göre farklılık gösterip göstermediği ayrıca test edilmiştir. Elde edile sonuçlara göre, Türkiye’de banka sermaye tamponları iş çevrimlerine karşı döngüsel hareket etmektedir. Ancak bu bulgu yatırım ve kalkınma bankaları için geçerli değildir. Diğer yandan, bankalara özgü özelliklerle ilgili panel regresyon sonuçlarına göre, büyüklük, karlılık ve risk ticari bankaların sermaye tamponlarının anlamlı belirleyicileri olarak ortaya çıkmaktadır. Aynı zamanda, bankacılık sektörünün yapısı ve 2008 küresel finansal krizinin banka sermaye tamponları üzerinde etkili olduğu gözlenmiştir. Sermaye tamponlarının bankaların kredi arzı üzerindeki etkisine dair bulgular ise ters yönlü bir ilişkiye işaret etmektedir. Çalışmanın bulguları, banka sermaye yeterliliğine ilişkin düzenlemeler ile Basel III uzlaşısı kapsamında önerilen ve yakın zamanda uygulamaya koyulan döngüsel sermaye tamponuna dair sonuçları bakımından önem taşımaktadır.

Girişimcilik ekosisteminin yapıtaşı startuplar, hızlı büyüme göstererek küresel pazara hâkim olmayı hedefleyen teknolojik girişimlerdir. Startupların başarısızlık nedenlerinin başında ise bulundukları pazarı iyi analiz edememe ve hedef müşteriye odaklanamama gelmektedir. Pazarlama faaliyetlerini yerine getirmeyen startuplar kısa sürede firma faaliyetlerine son verebilmektedir. Günümüzde startuplar üzerine birçok araştırma yapılmaktadır. Çalışmalar çoğunlukla Amerika Birleşik Devletleri ve diğer gelişmiş ülkelerde gerçekleşmektedir. Türkiye gibi gelişmekte olan ülkelerde araştırma sayısı oldukça azdır. Bu çalışmada Ankara’da faaliyet gösteren 141 startup’ın duyarlı pazar odaklılık ve proaktif pazar odaklılık yaklaşımlarının finansal performans, pazar performansı ve yenilik performansına etkileri incelenmiştir. Elde edilen bulgular ile ekosisteme fayda sağlayacak sonuçların ortaya konması ve literatüre katkı sağlanması amaçlanmaktadır.

Hatalar her zaman mükemmel olmayan bir mühendislik, tasarım veya satış faaliyetlerinin sonucu olarak meydana gelmez. Sinemaseverler tarafından kült film statüsüne kavuşmuş ve büyük bir maddi başarıya erişmiş yüzlerce kötü film varken, gişede hüsrana uğrayan yüzlerce iyi film vardır. Bu anlamda markaların hedef kitlede memnuniyetsizliğe yol açan negatif eylemlerini tanımlaması, analiz etmesi ve bilinçli deneyimlerde bulunması çok önemlidir. Ancak hataların değerli ve eşsiz yeni bilgiler üreteceğine dair inancın artmasına rağmen, hatalardan öğrenme sürecini açıklamada çok fazla yol alınamadığı ve daha fazla araştırmaya ihtiyaç duyulduğu sıklıkla belirtilmektedir. Bu çalışmanın amacı; çeşitli marka hikayeleri incelenerek i) işletmelerin ölüm katılığına düşmemek için öğrenmenin kaynağı olarak hataları nasıl kullanabileceğine dair yol haritası sunmak, ii) hatalardan öğrenme becerisi geliştirmeye engel olan unsurları ortaya çıkarmak ve iii) bu engellerin üstesinden gelme yollarını keşfetmektir. Böylelikle hatalardan öğrenme davranışına ilişkin ampirik ve deneysel çalışmalara katkı sağlanacağı umulmaktadır.

The purpose of this study is to examine the press within the framework of 'development journalism', a kind of journalism which is responsible for informing the public about the administrative changes and transformation processes experienced by the country, by considering the implementation of ‘new public management’ concept in Turkey within the domain of the ‘global governance’ and ‘globalization’ phenomenon affecting the nation states.  It was assumed in the design of the study that long or short term social problems could only be observed in a time tunnel and that the dense break points were spread over time.  When some anti-systematic tendencies are examined in the historical process, it can be seen that the order settled in the administrative area can be suddenly reversed by causal relation.  Issues in the background of the current problems in Turkey, has been characterized by a feature of uncertainty under the influence of populist politics that have been exhibited over time by different governments coming to power since the cold war.  There are many reasons for the historical background of some of the disruptions seen in the administrative application practices of the new public administration approach.  These include the late arrival of modernism to Turkey; followed by dependence on international aid programs under the US and EU; being a party to international economic and military agreements; the time required to adapt the definitions of internal law to domestic law; informing citizens about the change and assimilating the transformation.  There fore the relations between 'administration and the media' have been tried to be handled in connection with the global order.  In many non-Western countries, utilitarian practices of the new governance conception that developed after the abandonment of open or hidden colonial practices have also created an impact on the development of journalism and the differentiation of journalism genres.  'Development journalism' has played an important role in reflecting public administrative changes in Turkey to the public, which was never subjected to colonial rule by the West.  In this study, only a descriptive situation is detected.  It is expected to be useful for studies on the ‘administration’ and the media relations to be carried out later, during the change and transformation process of Turkey to a presidential system.  'Governance’ and media relations are handled together within the scope of new public administration practices and ‘global governance’ concept, which makes this work original.
