Individual variation in the development of the Western Vowel System of Utah
Authors: Bowie David
Published: June 2019

The BIT, BING, BET, BAT, BAN, BOOK, and BUT vowels of ten Utah English speakers (born 1883–1928) were analyzed over the course of several decades of their adult lives. Most speakers participated in the Western Vowel System by lowering BIT and BET, retracting BAT, and raising BAN, with some fronting BOOK and BUT. Speakers generally did not exhibit monotonic change across the years from expected positions for BET, BAT, and BAN, and for the most part for BOOK and BUT; however, most speakers showed change with regard to BIT, though speakers differed from each other on the direction of change. Even for those vowels with no consistent direction of intraindividual change, however, in many cases speakers were inconsistent in their production from year to year. Further, speakers’ envelopes of variation were different for various vowels, with the widest range of intraindividual variation in BET and BAT, less variation in BAN and BUT, and little in BIT and BOOK. It is suggested that the envelope of variation is at least as much as an important issue for studies of linguistic behavior across adulthood as any actual shift in linguistic behavior across real time.

Published: June 2019

The chemical oxygen demand (COD) of waste water from bamboo heat treatment is mainly organic macromolecule compound which degraded from hemicellulos, lignin and extractives. COD is toxic to aquatic organism and human body and very difficult to degrade. The paper studied the possibility of pre-treating the bamboo heat treated waste water (BHTWW) by combination of iron-carbon micro electrolysis and Fenton method. Orthogonal experiment was designed with 3 factors: the initial pH value, retention time and H2O2 dosage, and carried out with a dynamic sampling device with 2:1 iron carbon ratio. Results showed that the iron-carbon micro electrolysis and Fenton were proved to be a potential method in pre-treating BHTWW, and the optimum parameter should be pH 3.0, 40 min residence time and 0.5 % H2O2. After pre-treating, the removal rate of COD was 60.29 %, and B/C (biochemical oxygen demand after 5 days (BOD5)/COD increased from 0.037 to 0.32, the biodegradability was significantly improved. During the pretreatment, the nutrients in BHTWW had been oxidized, the double bound, conjugated double bond in guaiac lignin were opened or broken and degraded into more small molecular, nutrients such as TOC (total organic carbon) content, total nitrogen and total sugar content all decreased which all contributed for the increase of B/C. The microstructure of activated carbon appeared broken and collapses after pretreatment which indicated that they were eroded or involved during the micro electrolysis reaction.

Published: June 2019

Polystyrene-based wood plastic composites (WPCs) containing ammonium polyphosphate (APP) and iron (Fe) powder were prepared in this work by solution blending with the aid of an alternating magnetic field. The mechanical, electrical, thermal and fire performances of the WPCs were analyzed through mechanical testing, thermogravimetry and CONE calorimeter. The addition of Fe powder decreased the tensile strength and increased the impact strength. The APP promoted the formation of sufficient char on the material’s surface and enhanced the flame retardant properties. Furthermore, an alternating magnetic field was used to align the Fe powders. After the magnetic treatment, the electrical conductivity and thermal properties were found to increase considerably compared with those without treatment. The Agari model presented the most reasonable prediction of thermal conductivity as a function of Fe content among three classical thermal conduction models. According to the morphological observations, the iron particles in the composites tended to rearrange along the direction of the magnetic field after treatment, resulting in the enhancement of both thermal and electrical conductivities. The prepared WPCs in this study exhibited good flame retardant properties together with the acceptable mechanical properties of the composites.
Characterizations of PMMA-based polymer electrolyte membranes with Al2O3
Authors: Sun Cha Chee , You Ah Heng , Teo Lay Lian
Published: June 2019

Poly(methyl methacrylate) (PMMA)-based polymer electrolyte membranes are prepared through the solution cast method, with PMMA:ethylene carbonate (EC):LiCF3SO3:Al2O3 weight ratio of 55.13:18.34:24.5:2. The effect of Al2O3 filler grain sizes of 50 nm and 10 μm on the polymer electrolytes was studied in this work. From the Cole-Cole plot obtained through electrochemical impedance spectroscopy, the highest ionic conductivity for 50-nm Al2O3 in the PMMA-LiCF3SO3-EC-Al2O3 sample was measured as 1.52 × 10−4 S/cm at room temperature. The bonding formation among the host polymer and other additives in the polymer electrolytes has been studied using Fourier transform infrared spectroscopy. A strong occurrence of CH3 stretching mode has proven that nano size Al2O3 results in a much stronger bonding effect with the host polymer. The particle sizes were calculated by applying the Debye-Scherrer equation from the X-ray diffraction results. This work considers the effect of instrument broadening to further improve the accuracy of particle broadening for particle size calculation. The average particle size of nano size Al2O3 in the PMMA sample is calculated as 2.9693 nm. Moreover, a higher amorphousity level obtained from nano size filler polymer electrolyte of 98.5% computed from differential scanning calorimetry thermograms had also explained the achievement of high ionic conductivity in this work.

Promises and challenges of gender-sensitive epidemiology
Authors: Miani Céline , Batram-Zantvoort Stephanie , Wandschneider Lisa , Razum Oliver
Published: June 2019

Risk factor-oriented epidemiology was largely disconnected from sociological theory. Recently, efforts have been made to integrate more systematically gender as a social concept in epidemiology. An intersectional multi-level approach to gender-sensitive epidemiology could move beyond a male-female dichotomy, allowing to understand the interdependence between various sexual and social identities and mechanisms of discrimination, and explore the complexity of gender-related influences on health.

We study a nonlinear system of partial differential equations that describe rotating shallow water with an arbitrary constant polytropic index γ for the fluid. In our analysis, we apply the theory of symmetries for differential equations, and we determine that the system of our study is invariant under a five-dimensional Lie algebra. The admitted Lie symmetries form the

Beato, M, De Keijzer, KL, Leskauskas, Z, Allen, WJ, Dello Iacono, A, and McErlain-Naylor, SA. Effect of postactivation potentiation after medium vs. high inertia eccentric overload exercise on standing long jump, countermovement jump, and change of direction performance. J Strength Cond Res 35(9): 2616–2621, 2021—This study aimed to evaluate the postactivation potentiation (PAP) effects of an eccentric overload (EOL) exercise on vertical and horizontal jumps and change of direction (COD) performance. Twelve healthy physically active male subjects were involved in a crossover study. The subjects performed 3 sets of 6 repetitions of EOL half squats for maximal power using a flywheel ergometer. Postactivation potentiation using an EOL exercise was compared between a medium (M-EOL) vs. high inertia (H-EOL) experimental condition. Long jump (LJ) was recorded at 30 seconds, 3, and 6 minutes after both EOL exercises and compared with baseline values (control). The same procedure was used to assess countermovement jump (CMJ) height and peak power and 5-m COD test (COD-5m). A fully Bayesian statistical approach to provide probabilistic statements was used in this study. Long jump performance reported improvements after M-EOL and H-EOL exercise (Bayes factor [BF10] = 32.7, strong; BF10 = 9.2, moderate), respectively. Countermovement jump height (BF10 = 135.6, extreme; BF10 > 200, extreme), CMJ peak power (BF10 > 200, extreme; BF10 = 56.1, very strong), and COD-5m (BF10 = 55.7, very strong; BF10 = 16.4, strong) reported improvements after M-EOL and H-EOL exercise, respectively. Between analysis did not report meaningful differences in performance between M-EOL and H-EOL exercises. The present outcomes highlight that PAP using an EOL (M-EOL and H-EOL) improves LJ, CMJ height, CMJ peak power, and COD-5m in male athletes. The optimal time window for the PAP effect was found for both EOL conditions from 3 to 6 minutes. However, M-EOL and H-EOL produce similar PAP effect on LJ, CMJ, and COD-5m tasks.

Abade, E, Silva, N, Ferreira, R, Baptista, J, Gonçalves, B, Osório, S, and Viana, JL. Effects of adding vertical or horizontal force-vector exercises to in-season general strength training on jumping and sprinting performance of youth football players. J Strength Cond Res 35(10): 2769–2774, 2021—Football is characterized by short-term high-intensity triaxial activities that require optimized neuromuscular capacity. Thus, training routines must consider the direction of force application, particularly when strength exercises are performed. This study aimed to explore the effects of adding vertical or horizontal force-vector exercises to a 20-week in-season general strength training program on jumping and sprinting performance of youth football players. Twenty-four well-trained male under-17 players participated in this study and were randomly assigned to a control, vertical, or horizontal training group. Control group performed a general strength training program (free weights, eccentric-overload, and body mass exercises) once a week during 20 weeks. Vertical and horizontal groups additionally performed back-half-squat or barbell hip-thrust, respectively. Vertical group improved vertical jump (VJ) (squat jump, likely 4.5; ±4.4% and countermovement jump, likely 4.9; ±4.1%), horizontal jump (HJ) (most likely 7.5; ±2.7%), and sprint (10 m, likely −1.6; ±2.0% and 20 m, very likely −3.3; ±1.6%). The horizontal group showed unclear results in VJ; however, large improvements were observed in HJ (most likely, 13.0; ±4.8%), 10 m and 20 m (very likely −3.0; ±1.8% and most likely −3.8; ±1.0%, respectively). Back-squat and hip-thrust showed an important transference effect to both jumping and sprinting performance. If considering the effects of back-squat on VJ, hip-thrust improved HJ and sprint to a greater extent. This study reinforces the importance of performing both vertical and horizontal force-vector exercises to enhance physical performance during football in-season, even when performed only once a week.
Relationships Between Midthigh Pull Force Development and 200-m Race Performance in Highly Trained Kayakers

Pickett, CW, Nosaka, K, Zois, J, and Blazevich, AJ. Relationships between midthigh pull force development and 200-m race performance in highly trained kayakers. J Strength Cond Res 35(10): 2853–2861, 2021—While increased lower-limb force production during kayaking has been shown to be related to increased boat velocity, poor relationships between maximal deadlift test performances and 200-m race time have been observed previously. This discrepancy may result from either a lack of movement pattern or temporal force production specificity between the test and kayak paddling. The isometric midthigh pull (MTP) test is commonly used in strength testing and quantifies temporal and peak force production, with the lower limbs positioned in a more kayak-specific manner than the deadlift test. Midthigh pull force data collected from 11 high-level kayak athletes were analyzed for both reliability and correlations with 200-m race time and deadlift isoinertial strength 3 repetition maximum (3RM). Strong consideration was given to the collection, processing, and analysis of the MTP data, which markedly affected the study results. Correlations between race time and MTP peak force and rates of force development were poor to moderate (r = −0.49 to 0.07). Strong to very strong relationships (r = 0.66–0.79) were found between forces developed early in the MTP (<0.15 seconds) and deadlift 3RM strength tests but were poor for later time-specific force development (r ≤ 0.12). However, poor reliability was found for force measured up to ≤0.25 seconds from the point of force onset (intraclass correlation coefficient >0.8). Owing to the relatively weak relationships with 200-m race time, and the large variability of the data, it may not be wise to include the MTP in the testing and training of 200-m kayak athletes.
Auxiliary Particle Filter–Based Multisensor Data Fusion for Quantification of Corrosion in Aerostructures
Authors: Ahmad S. Taufeeq , Khan Tariq Mairaj Rasool , Yousuf Waleed Bin
Published: June 2019

The identification of structural flaws and subsequent management is significant for health monitoring of aviation structures. Wall thickness loss can occur because of corrosion in exposed aerostructures, thereby reducing the strength of the structure. This may impose prolonged downtimes for repair and replacement activities if not detected at early stages. Eddy current testing (ECT) is a viable technique to detect such anomalies. Fusing multifrequency data produces better results because of complementary features of each contributing mode. Particle filter–based methods have already been proposed to detect and quantify flaw profiles of corrosion damage to an aircraft structure using a multifrequency ECT data fusion technique. However, to address the associated drawbacks, an auxiliary particle filter (APF) method is proposed here. In APF, the proposed importance density is a mixture of the prior state and the latest measurements, yielding focused estimation into a high-likelihood region. Simulation results are presented to demonstrate effectiveness of the proposed technique to quantify damages in aerostructures.

The Three Enigmas of Palestinian Literature
Authors: Abu-Remaileh Refqa
Published: June 2019

As an introduction to the Journal's literary feature, this contribution aims to shed light on recent scholarship on Palestinian literature with a view to integrating discussions of literature more concretely within the broader field of Palestine studies. The contribution structures the discussion of the articles by Amal Eqeiq and Nora Parr around three enigmas that preoccupy scholars of Palestinian literature: writing a national literature without a nation-state, writing silence and nonlinearity, and writing fragmentation and wholeness. It highlights that challenges for scholarship on Palestinian literature revolve around rethinking conventional categorizations, canonizations, and periodizations to better understand how a national literature emerged in a context of exile, fragmentation, and statelessness, and how processes of cultural production operate in extranational conditions.
From Haifa to Ramallah (and Back): New/Old Palestinian Literary Topography
Authors: Eqeiq Amal
Published: June 2019

This article explores border crossing and the Palestinian city as a literary metropolis—two major themes in the works of emerging Palestinian novelists in Israel. It looks at the “re-Palestinization” of urban space by writers who belong to a post-Oslo generation of Palestinian intellectuals that left villages and small towns in Israel to go and study, work, and live in the city. What distinguishes the literature of this generation is its negotiation of border crossing in a fragmented geography and its engagement with the city as a space of paradoxical encounter between a national imaginary and a settler-colonial reality. Based on a critical reading of their works, the article argues that Adania Shibli and Ibtisam Azem challenge colonial border discourse, exposing the ongoing Zionist erasure of the Palestinian city and creating a new topography for Palestinian literature. The article also traces the role of these writers in the “twinning” of Haifa and Ramallah starting in the late 1990s, and it examines how this literary and cultural “sisterhood” informs spatial resistance.
U.S. Recognition of Golan Heights Annexation: Testament to Our Times
Authors: Kattan Victor
Published: June 2019

On 25 March 2019, U.S. president Donald Trump signed a proclamation recognizing the occupied Golan Heights as part of Israel. The Golan Heights proclamation, which endorses Israel's annexation of the territory captured from Syria in the 1967 war, was issued two weeks before the Israeli general election in a photo-op with Prime Minister Benjamin Netanyahu at the White House. Undermining internationally agreed-upon norms prohibiting states from recognizing the annexation of territory by force, the proclamation could have detrimental consequences for the international legal order, providing a precedent for other states to take steps to annex territory they claim is necessary for their defense.

Analysis of the impact of forging and trimming tools wear on the dimension-shape precision of forgings obtained in the process of manufacturing components for the automotive industry
Authors: Hawryluk Marek , Kondracki Piotr , Krawczyk Jakub , Rychlik Marcin , Ziemba Jacek
Published: June 2019

The study presents the results of an analysis of the manufacturing process of a yoke-type forging for automotive industry with the
use of numerical modelling and 3D scanning techniques, taking into account the gradual wear of both forging tools and trimming to
determine the mutual impact of their operation on the dimensional accuracy of the forgings. The performed analysis included the 4
variants which are that have the most common place in the industrial process that is, for a combination of new and partly worn out
die inserts (used during hot forging) and new and partly used cutting tools used for cold trimming. The first stage involved modelling
of a hot die forging process. Next, the obtained results were implemented into second modelling stage, which involved a simulation
of a cold trimming process of a flash, with the use of the normalized Cockcroft-Latham fracture criterion, with the consideration of
eliminating the removed elements, for which the cracking value has been exceeded. The obtained results was verified by means of
a case study under industrial conditions for the least favourable operating conditions of both types of tools and their impact on the
dimension-shape precision of the forgings. These results allowed for a more complete analysis of the trimming process for a variety
of operating conditions and the confirmation of the correctness of carried out numerical modelling, and thus the possibility of its
use in combination with scanning technique to computer-aided manufacturing processes. The proposed solution allows the selection
of optimum conditions for implementation of the processes of forging and trimming because of their use to provide the required net
shape forgings.
Influence of the local defect distribution on vibration characteristics of ball bearings
Authors: Liu Jing , Xu Yajun , Wang Linfeng , Xu Zidan , Tang Changke
Published: June 2019

Local defects in ball bearings may occur at the center line of raceway and its surrounding areas. However, most current studies
were concentrated in studying the influence of the local defect located at the centerline of raceway on the bearing vibrations, where
the effects of local defects surround the centerline were ignored. To overcome this problem, based on Hertzian point contact theory
and multi-body dynamic algorithm, a multi-body dynamic model considering the offset and angular distributions for a ball bearing with a local defect on its outer raceway is established. The influences of offset distance and skew angle between the geometric
center of local defect and the centerline of outer raceway on the bearing vibrations are investigated. The relationship between
the offset distance and the impulse waveform characteristics is obtained, as well as that between the skew angle and the impulse
waveform characteristics. The results show that the offset distance and skew angle of the local defect have a great influence on
the time-domain impulse waveform characteristics of the bearing accelerations. This paper can provide a useful guidance for the
accurate diagnosis of early local fault in the ball bearings.
The use of a supply chain configuration model to assess the reliability of Logistics processes

Published: June 2019

The article presents an approach to assessing the reliability of logistics processes implemented in supply chains in terms of time
losses resulting from the selection of a variant of material flows in the supply chain. In order to define this indicator, a mathematical model of the supply chain has been developed, i.e. the parameters of the research problem, the decision variables, the
constraints and the evaluation criteria. The method of evaluating the reliability of the system is presented in diagram form. The
algorithm was verified based on experimental data. In order to evaluate the reliability of the logistic processes for the sample
supply chain, a simulation model was developed that determines the time losses in the points and linear elements of the examined
chain. Time losses are dictated by traffic delays resulting from traffic congestion on particular sections of the route and road junctions and delays in point elements in the supply chain.
Reliability evaluation for vhf and uhf bands under different scenarios via propagation loss model
Authors: Li Xiang , Huang Hong-Zhong , Li Yi-Fan , Li Yan-Feng
Published: June 2019

The significant effect of path loss on the reliability of very high frequency (VHF) and ultrahigh frequency (UHF) bands propagation has drawn much attention. Previous works mainly focus on the reliability evaluation for infrastructures and basic equipment,
however, its propagation reliability has not been taken into full consideration. This paper proposes a new method for evaluating
the reliability of the wireless communication based on the analysis of the traditional outdoor wave propagation loss models. In the
reliability evaluation of the radio communication, we firstly consider the transmission frequency, the antenna height, the cell type
and the communication distance. Then, we use a lognormal distribution to fit the random distribution curve of the communication
distance so that the relationship between the path loss value and the reliability can be analysed. We further derive the probability
distribution function (PDF) and the cumulative distribution function (CDF) of the path loss value from different antenna correction factors, cell type correction factors and terrain correction factors. Finally, we calculate the radio communication reliability
values at different frequencies based on the threshold of the propagation loss value. Compared with the reliability degree only
considering the communication distance threshold, the influence of environmental factors on the reliability of the VHF and the
UHF radio propagation has been analysed
Thermal properties of natural ester and low viscosity natural ester in the aspect of the reliable operation of the transformer cooling system
Authors: Dombek Grzegorz , Nadolny Zbigniew , Marcinkowska Agnieszka
Published: June 2019

The paper presents the results of comparative studies of thermal properties of various types of natural esters used as electroinsulating liquids in transformers. Adequate thermal properties of electro-insulating liquids ensure reliable work of transformers.
Two natural esters were selected for the study – one commonly used in distribution transformers, the other characterized by low
viscosity. Fourier Transform Infrared Spectroscopy and UV-Visible spectroscopy were used to examine the chemical structure of
the examined esters. Properties such as thermal conductivity coefficient λ, kinematic viscosity υ, specific heat cp, density ρ, and
thermal expansion coefficient β were analyzed. Heat transfer factor α of the liquid was calculated on the basis of obtained properties. This factor defines the ability of an insulating liquid to heat transport in the transformer, thus determining its reliability. The
authors put forward a thesis that a low viscosity natural ester will have a higher heat transfer factor α due to its low viscosity,
which affects the factor α. The analysis of thermal properties was carried out for the following temperatures: 25, 40, 60, and 80°C.
On the basis of the calculated factor α, the temperature drops in the transformer filled with the analyzed types of natural esters
were determined. It has been shown that if a low viscosity natural ester is used in the cooling system of the transformer, the temperature of the hot-spot will be lower. This fact may contribute to more reliable work of transformers and extend its service life.

Published: June 2019

Purpose: Trunk control is the key component for functional movements and affected by limited blood circulation in neurological diseases. Although the relationship between trunk control, gait and functional independence is clear neurological conditions as stroke, it is not known in patients who underwent surgery for brain tumor. The aim of this study is to determine the relationship between trunk control, functional independence and functional capacity in patients with brain tumors early period after surgery.       Materials and Methods: Trunk control, functional mobility and independence of twelve patients with brain tumor were evaluated by 2-Minute Walk Test (2MWT), Trunk Impairment Test (TIS) and Barthel Index, respectively in early postoperative period.  Results: Functional mobility was positively correlated with total and static trunk control (p=0.028, r=0.629 for total trunk control and p=0.029, r=0.627 for static trunk control). Functional independence was correlated to total trunk control (p=0.023, r=0.674).Conclusion: Functional mobility was closely associated with trunk control and functional independence in patients with brain tumor early period after surgery. Intensive evaluation that targets trunk control early after surgery should be done to regain better functional mobility for functional independence.

Published: June 2019

Kalkınmanın dinamik bir olgu olması, zaman içinde hedef ve stratejilerin de değişmesine neden olmaktadır. II. Dünya Savaşı’na kadar uzanan dönemde iktisadi analizlerde mekân yerine zaman kavramına önem verilmiştir. Kalkınmanın temelinde yer alan bölgesel kalkınma, özellikle II. Dünya Savaşı sonrasında mekânlar arasında gözlemlenen kalkınma farklılıkları nedeniyle iktisatçıların ve politika yapıcıların dikkatlerini çekmiştir. Mekânsal temelli olarak açıklanmaya çalışılan bu eşitsizlik uygulanan politik yaklaşımlarda da önemli dönüşümleri beraberinde getirmiştir. Merkeziyetçilikten uzaklaşarak giderek yerelleşmeye dönük geliştirilen teorik ve politik yaklaşımlar hem yeni kuramların hem de yeni kurumsal oluşumların ortaya çıkmasını sağlamıştır. Bu çalışmada Geleneksel Bölgecilikten,  Yeni Bölgecilik akımına geçişte yaşanan teorik dönüşümler incelenirken bu dönüşümlerin Türkiye’deki bölgesel kalkınma politikaları üzerinde yaratmış olduğu yansımalar ortaya konmaktadır.

Authors: FIRAT Muhammet , İLHAN Süleyman
Published: June 2019

Çingeneler günümüzde,
yoksulluk ve sosyal dışlanmayı çok dramatik biçimde deneyimleyen dezavantajlı
gruplardan biridir. Giderek yerleşik hayata geçmelerine rağmen, yoksulluk ve
dışlanmanın nesnesi olmaya devam etmektedirler. Bu
çalışmada, Malatya’da yaşayan Çingenelere yoksulluk ve sosyal dışlanma
bağlamında yaklaşılmaktadır. Bu kapsamda,
Çingenelerdeki yoksulluk ve sosyal
dışlanma; etnisite, yoksulluk nedenleri, göç ve göçe bağlı sorunlar, eğitim
hizmetlerinden yeterince yararlanamama, istihdam olanaklarına yeterince
ulaşamama ya da güvencesiz çalışma, sosyal güvenlik ağlarından yoksun olma,
sosyal yardımlardan faydalan(ama)ma, sağlıksız konutlarda yaşama, ayrımcılık
vb. dezavantajları içermektedir. Araştırmada, Çingenelerin hem kültürel hem de sosyo-ekonomik açıdan
“dezavantajlı bir grup” olduğu, yoksulluk ve sosyal dışlanmayı şiddetli bir
şekilde deneyimlemelerinde kendi paylarının da bulunduğuna inandıkları
saptanmıştır.
Women’s Discrimination in Engineering Faculties: A View from Turkey
Authors: TEPE Fatma Fulya
Published: June 2019

The aim
of this research is to provide support for the hypothesis that academic women
are being subjected to acts and attitudes of a gender discriminatory nature in
the Turkish context, too. This study can be best described as a
phenomenological research. It is based on sixteen interviews made with fifteen
women and one male academic between 2008 and 2013 in engineering departments of
Turkish universities. Close reading was used to interpret the data. In the
interviews, academic women report that they have experienced discrimination in
hiring and promotions, as well as discouragement and belittlement due to their
gender. The conclusion is that more research is needed to further understand
the extent and nature of gender discrimination at Turkish universities.
Üretim Endüstrisi Dijital Dönüşüm Süreci Kavramsal İlişki Haritası
Authors: APİLİOĞULLARI Lütfi
Published: June 2019

Üretim endüstrisindeki
KOBİ’lerde Endüstri 4.0 / dijitallaşme üzerine çalışmalar yapılmaktadır. Ancak,
işletmelerin birçoğu yanlış stratejiler ve uygulamaların sonucu olarak,
dijitalleşme konusunda istedikleri ivmeyi yakalayamamakta ve rekabetçi
olamamaktadırlar. Bu sonuç, Endüstri 4.0’a geçiş yöntemlerinin
bilinmemesi/uygulanamaması, hangi teknolojinin ne zaman/ nasıl kullanılması
gerektiğinin anlaşılamaması ya da stratejik bakış açısı eksiklikleri gibi etkenlerden
kaynaklanabilmektedir. Kısıtlı imkana sahip olan Kobilerin, gelişim gösterip,
dijital çağa ayak uydurabilmeleri için etkin bir dijital dönüşüm yol haritasına
ihtiyaçları bulunmaktadır. Bu çalışmada, Kobilerin dijital dönüşüm sürecinde
başarılı olabilmeleri için, uygulamaları gereken kavramların birbirleri ile
ilişkisi incelenmiş ve genel hatları ile bir yol haritası modeli çıkarılmaya
çalışılmıştır.

Børneperspektiv – en populær flydende betegner
Authors: Warming Hanne
Published: June 2019

Rigtig mange børne- og ungeforskere, såvel som praktikere i det pædagogiske felt, hævder at anlægge et børneperspektiv. Imidlertid bruges begrebet på vidt forskellige måder – ja, nogle gange ligefrem modsatrettet, herunder som begreb for voksnes angivelige bedreviden om barnets bedste, børns egne perspektiver og et børnefokus i samfundsmæssige analyser. Dette skitseres indledningsvis, hvorefter der argumenteres for at reservere begrebet til de voksnes forsøg på at forstå (og formidle) børnenes perspektiver, mens børnefokusset i den samfundsmæssige analyse begrebsliggøres som barndomsperspektiv. Herefter rettes blikket mod de metodologiske og etiske muligheder og udfordringer i forbindelse med at anlægge et børneperspektiv i forskning og praksis, herunder umuligheden i at krybe under huden på ”den anden”. Afslutningsvis rettes blikket mod en nyere strømning inden for barndomsforskningen og socialvidenskaben mere generelt, nemlig den ontologiske vending. Denne vending kan på den ene side hævdes at være ”gammel vin på nye flasker”; på den anden side kalder den ikke desto mindre på fornyet etisk opmærksomhed og inspirerer til nye metodologiske greb til at analysere tilblivelser af perspektiver på børn og af børns perspektiver.
Hvordan forstår vi barn og barndom?
Authors: Tingstad Vebjørg
Published: June 2019

Denne artikkelen undersøker ontologiske og epistemologiske posisjoner som har hatt en ikke ubetydelig innflytelse på teoretisk perspektivering og metodiske overveielser i barne- og barndomsforskning, spesielt de siste 30 årene. Artikkelen er basert på en tematisk lesning av 4445 sammendrag av artikler publisert i fire tidsskrift (tre internasjonale og ett nordisk) i årgangene 2015, 2016 og 2017, og drøfter fire tema som gikk igjen i dette materialet. Disse temaene konfronteres med og utfordres av forskningslitteratur innen det tverrfaglige forskningsfeltet Childhood Studies med den hensikt å bedre kunne reflektere over og stille spørsmål ved perspektiver en som forsker kan ta for gitt. Temaene er barns stemmer, det kompetente barn, forholdet mellom struktur og aktør og sosial konstruksjonisme. Artikkelen gir innsyn i sentrale posisjoner og kontroverser og viser hvordan begreper som lett blir tatt for gitt, på ingen måte er tydelige eller nøytrale, men ofte både tvetydige og normative. Det argumenteres i artikkelen at dette er en utfordring for forskningsfeltets teoriutvikling.
Clasificación de especies arbóreas según su capacidad para remover material particulado del aire en el Valle de Aburrá
Authors: Vasquez Bedoya Manuela , Arroyave Maya María del Pilar
Published: June 2019

La contaminación atmosférica es un problema global y Colombia no es ajeno a esta problemática. Específicamente, el Valle de Aburrá ha presentado elevados niveles de material particulado en el aire (MP) que sobrepasan los límites establecidos por la Norma Colombiana de Calidad del Aire y por la Organización Mundial de la Salud (OMS). En el presente trabajo, se realizó una clasificación de las 100 especies arbóreas más comunes en Valle de Aburrá que mejor controlan el MP, a partir de sus rasgos funcionales. Retrophyllum rospigliosii, Inga densiflora, Zygia longifolia, Bauhinia picta y Calliandra haematocephala fueron las cinco especies nativas con  el mayor potencial de remoción. Se sugiere que aquellas especies que se encuentran por encima del promedio 17.8 en la clasificación sean consideradas en planes de siembra orientados a mejorar la calidad del aire dentro del Valle de Aburrá.
