FOREIGN EXPERIENCE OF STRATEGIC PLANNING FOR REGIONAL DEVELOPMENT
Authors: Kuharskaya Natalia
Published: October 2020

Introduction. The strategic goals of socio-economic development of the regions of Ukraine, which were set in numerous concepts, strategies, programs and other strategic documents, both at the state and regional levels, were not achieved. This is due to the lack of interconnectedness of these documents, the mechanism of control over their implementation and inconsistency with the real needs of the regions.
Goal. The aim of the study is to reveal the organization of strategic planning of regional development in France, Germany, USA, Canada and Japan, which may become the basis for further, more thorough, strategic planning of regional development in Ukraine.
Results. The creation and implementation of the French regional development strategy is seen as an ongoing process with an emphasis on restructuring the regions, maximizing their potential, supporting small and medium-sized businesses by coordinating the state plan with private business and coordinating their interests with the state. Considerable attention is paid to the ecological component of development at the meso level. The main requirements of strategic planning in Germany are: consensus of economic interests of major regional stakeholders; identification of specific participants in the strategic planning process, coordinators and users of the achieved results; establishing clear priorities in the development of the territory provided with resources; the adequacy of the coordinator's organizational structure in relation to the process of achieving the stated goals in the strategic plan. Strategic planning of regional development in the United States is based on total computerization, based on a single network of nine economic regions of the country, which is the basis for a comprehensive approach to regulating regional development in accordance with national strategy, establishing the format of effective plans and reports and procedures. in case of non-compliance, personal responsibility for achieving results. In Canada, it is important in strategic planning to test the tools provided for in the strategic plan in certain territorial areas of administrative entities.
The mechanism for implementing strategic planning in Japan is based on a strong focus on achieving group goals, whereby the central government determines the range of tools for regional development, regional bodies are responsible for its implementation, and private business plans its activities based on national strategy indicators. Improving foreign experience should be built taking into account the specifics of our country.

Published: October 2020

Introduction. Increasing of interest in corporate social responsibility has become currently important in Ukraine only in recent years, at a time when the concept of corporate social responsibility has been developing around the world for several decades. Domestic enterprises rarely use the principles of social responsibility in their activities. The level of familiarity with this topic is insufficient to understand the importance of the issue for business, and most often such a position is argued of financial insolvency.
Purpose. Given the above, it is important to describe the process of origin of the concept of "corporate social responsibility", to understand the reasons for its emergence, as well as to formulate a modern interpretation of the term. This will prove its importance in the light of current trends in the economy as a whole, show the need for implementation and use in all economic entities.
The theoretical basis of the research is the basic principles of management and economics. To carry out scientific searches on the topic were used general scientific methods of cognition, methods of logical analysis, generalization, synthesis.
Results. The article deals with the origin of the concept of "corporate social responsibility", historical preconditions for its emergence. The transformation of understanding of corporate social responsibility from unsystematic activity in the field of charity to more specific realization of it as a component of the overall strategy of enterprise management is observed. The main landmarks in the history of its development and the role of the state in fixing this concept in the consciousness of business are determined.
Various approaches to the definition of CSR are presented. The applicability of the concept for modern companies in the context of matching the trends of business sphere and the needs of society is determined. The importance of CSR for the enterprise and society as a whole in the current conditions of workplace and market relations is formulated.

Published: October 2020

The interface condition between the graphene channel and aluminum oxide (Al2O3) gate insulator in a graphene field-effect transistor (FET) has been analyzed. The hard X-ray photoelectron spectroscopy technique was employed to analyze the interface. In the obtained C1s spectra, a small peak was found at 284.2 eV, which was considered to be derived from a covalent bond between the graphene and Al2O3. In the pulsed S-parameters measurements, it was found that the direction of the Dirac voltage shift matched the polarity of the applied voltage stress. The Dirac voltage shift demonstrated that there were electron traps at the interface, degrading the FET performance such as the cutoff frequency. It was concluded that the unexpected bond at the interface formed electron traps whose energy level located near the conduction band minimum and that the Dirac voltage shifted in accordance with carrier capturing or emitting by the traps.

Authors: Kishnani Kanhaiya Lal , Choudhary Ashwini , Singh Satyajeet
Published: October 2020

Mucoepidermoid carcinoma tumours are less common and approximately 5% of tumours of salivary glands. They are slow growing usually asymptomatic at beginning which cause delay in diagnosis. Mucoepidermoid carcinoma tumours commonly occur predominantly in women in fourth to fifth decades of age and their occurrence in the upper lip area is extremely rare. Tumours of upper lip pose difficulty to airway management team due to their proximity to airway, wide resection surgery and repair. Care should be taken to avoid any kind of pressure on swelling during intubation to avoid tumour rupture or tumour bleed.
The prognosis of low-grade Mucoepidermoid carcinoma depends upon its clinical stage and histological grade. Low-grade MEC has better 5-year survival rate in comparison to intermediate and high grade tumours. Cure rate of MEC is excellent after wide local resection.

Published: October 2020

AIM: The purpose of this study was to attain floating norms for the MMBP-Wits and 𝛽 angle in adult Chennai population that can aid in proper diagnosis and treatment planning of different cases. Methods: Lateral cephalograms were acquired from 100 subjects (50 males and 50 females; mean age: 18-25 years) with pleasant profile and well-balanced and a near-ideal occlusion. Land mark identification and tracings were carried out manually on 0.003’ thickness acetate film. The ANB angle, the 𝛽-angle, the MMBP-Wits were measured. Four Other angular cephalometric parameters which included the SN/PP, SN/MP, SNA, and NSB angles were also measured. Multiple regression models were used to quantify the correlation of the ANB angle, MMBP-Wits and 𝛽 angle with each other and also with four other angular cephalometric parameters mentioned above. RESULTS: All the three cephalometric parameters of antero-posterior maxillary-mandibular relationship had considerable association with the explanatory variables with 𝑅2 range from 0.183 to 0.212 for the ANB angle and the MMBP-Wits, respectively. The ANB angle was considerably related with all the explanatory variables. In particular, the NSBa, SNA, and SN/MP angles were certainly associated with the ANB angle, whereas the SN/PP angle was inversely associated. On the contrary, both the 𝛽 angle and MMBP-Wits were considerably associated with SNA and SN/MP angles. These explanatory variables showed positive and inverse association with the MMBP-Wits and the 𝛽 angle. CONCLUSION: (i) The ANB angle is prone to have considerably more geometrical distortion as compared to the MMBP-Wits and the 𝛽 angle. (ii) Floating norms have been given to individualize the reference values for both the MMBP-Wits and 𝛽 angle.

Published: October 2020

OBJECTIVES : To study the role of dexmedetomidine on emergence agitation and its effect on extubation in paediatric adenotonsillectomy. Our study involves the assessment of postoperative pain by Objective Pain Scale and need for rescue analgesia and other untoward events in PACU. The study also included the comparision of post operative recovery time by Modified Aldrete Recovery Score using dexmedetomidine and normal saline in adenotonsillectomy for pediatric patients. METHODS : After induction of general anesthesia patient was put on controlled ventilation and maintained on sevoflurane 1.5-2% with 66% O2 and 33% N2O. At the end of surgery patients received either dexmedetomidine or normal saline over a period of 5 minutes, sevoﬂurane and nitrous oxide were discontinued, and residual muscle relaxation was reversed. Tracheal extubation time (time from anesthetic gas discontinue to tracheal extubation) and emergence time (time from anesthetic gas discontinue to eye opening on command) were recorded. Incidence of untoward airway events after extubation were also noted. The subject’s postoperative behaviour was assessed using Pediatric Anesthesia Emergence Delirium (PAED). In PACU, the intensity of pain was assessed by using an observational pain score (OPS). Any untoward events were noted and patient was shifted as per modified PACU score. RESULTS: In this randomized comparative study, single dose of dexmedetomidine (0.5mcg/kg) was found to be associated with a statistically significant decrease in the incidence of emergence agitation along with smooth extubation in pediatric patients undergoing adenotonsillectomy with sevoflurane anesthesia. In addition, lower incidence of post-operative nausea and vomiting, lower pain score and shorter duration of stay in post-anesthesia care unit were observed. Although it was seen that the extubation was prolonged in the dexmedetomidine group in comparison to the placebo. CONCLUSION: Dexmedetomidine reduces emergence agitation and provides smooth extubation in pediatric adenotonsillectomy patients on sevoflurane anesthesia.
SECONDARY INTERNAL OSTEOSYNTHESIS WITH LOCKING PLATES FOR RECENT OR OLD OPEN FRACTURE OF THE TIBIA, OVERLAPPING PROVISIONAL EXTERNAL FIXATOR PIN SITES: IS THE INFECTION RISK INCREASED?
Authors: Kumar Garg Uttam , K Shukla S. , K Pathak S. , A Usmani I.
Published: October 2020

Twenty-two patients had a severe open fracture of the tibia that was initially treated by external fixation and subsequently by locking plate. The external fixation had been maintained for an average of fifty-nine days (range, 15 to 240 days). The mean interval between removal of the external fixator and plating was twenty-six days (range, 10 to 44 days). five out of twelve patients who had an infection at one or more of the pin sites, developed one superficial and four deep infection. In comparison, only one of the ten patients who had not had a pin-site infection had a superficial infection. An analysis of other variables, including the duration of external fixation, wound coverage, other injuries, and the type of fracture, showed that none was a predictor of infection either at the pin sites or around the plate. We concluded that a pin-site infection that develops during external fixation is a contraindication to the subsequent plating in patients who have a fracture of the tibia.

Published: October 2020

In this paper, we address the problem of energy efficient resource optimization for downlink transmission in user-centric ultra-dense networks enabled by wireless access via nonorthogonal multiple access and wireless backhaul via beamforming. Our objective is to maximize the system energy efficiency by optimizing user/access point scheduling, subchannel assignment, and power allocation jointly. The problem is formulated as a nonconvex mixed-integer nonlinear programming problem which is NP-hard. We then transform it into a convex subproblem using the sum-of-ratios decoupling and the iterative successive convex approximation method. An overall algorithm is further developed to solve the subproblem iteratively. Simulation results show that the proposed algorithm has improved the system-wide energy efficiency significantly when compared to the benchmark scheme.
A simple multi-feature classification to recognize human emotions in Images
Authors: Ipe Navin
Published: October 2020

Emotion recognition by the human brain, normally incorporates context, body language, facial expressions, verbal cues, non-verbal cues, gestures and tone of voice. When considering only the face, piecing together various aspects of each facial feature is critical in identifying the emotion. Since viewing a single facial feature in isolation may result in inaccuracies, this paper attempts training neural networks to first identify specific
facial features in isolation, and then use the general pattern of expressions on the face to identify the overall emotion. The reason for classification inaccuracies are also examined.

Towards an Expanded Conception of Publication Bias
Authors: Nelson Nicole
Published: October 2020

This short essay argues for an expanded conception of publication bias. In addition to consideringthe selective publication of results, I argue that we need to also consider the selective publicationof epistemic by-products—observations and knowledge that scientists accumulate incidentallyin the process of carrying out their work. There are three reasons why we should be concernedabout the exclusion of epistemic by-products from the published literature: first, because theyplay an important role in robust replication attempts; second, because their absence can resultin misplaced scientific certainty; and third, because they contribute to a holistic understandingof natural phenomena. However, identifying and addressing publication bias against epistemicby-products and other undervalued forms of knowledge is more difficult than identifying biasagainst quantitative findings. I argue that scientific pluralism and making data publicly accessibleare two potential remedies for addressing this form of publication bias.

In the last decade, the chimney EVAR (CHEVAR) has rapidly evolved. It started as a bailout option to save aortic branches in case of inadvertent coverage during EVAR and developed within 10 years of published evidence to a valid endovascular treatment option of complex abdominal aortic pathologies. Recently, the technique was included in the ESVS 2019 guidelines for treatment of abdominal aortic aneurysms (AAA).4 Despite this tremendous evolution from a bailout approach to a therapeutic modality a gutter-related endoleaks remain the Achilles heel of the technique.

Image encryption scheme based on a Gaussian apertured reality-preserving fractional Mellin transform
Authors: Mengmeng Wang  , Pousset Yannis , Carré Phillippe , Perrine Clency , Nanrun Zhou  , Jianhua Wu
Published: October 2020

An image encryption scheme based on a Gaussian apertured reality-preserving fractional Mellin transform (GARPFrMT) is proposed. The GARPFrMT was realized in the diffraction domain. The Gaussian aperture, like a soft aperture, improved the amount of light that passed through the lens compared to a hard aperture and reduced the light leakage at the edge of the lens, assisting to some extent in resisting direct attacks. In the proposed scheme, the reality-preserving transform was constructed in the diffraction domain to ensure that the cipher-text is real. The GARPFrMT is a nonlinear transformation used for eliminating potential insecurity existing in the linear image encryption system. In order to further enhance the security of the encryption system, an Arnold transform, and a bitwise XOR operation were employed for permutation and scrambling in the encryption process. Simulation results and theoretical analysis show that the proposed algorithm is feasible and capable of withstanding several common attacks.
Tuning the localized surface plasmon resonance of “core-shell Ag nanoparticles on dielectric substrates” to near-infrared window: applications to surface-enhanced Raman spectroscopy
Authors: Salimian Sina , Soofi Hadi
Published: October 2020

In this article, plasmonic characteristics of SiO2-Ag and hollow core Ag nanoparticles placed on dielectric substrates are investigated and tuned to the NIR wavelength spectrum for biological applications. It is shown that by placing the core-shell Ag nanoparticles on a dielectric substrate and exciting the normal plasmon mode of the nanoparticle, it is possible to obtain strong plasmon resonances at wavelengths as long as λ = 700 nm which exhibits a red shift of more than 300 nm compared to the resonance of freestanding pure Ag nanoparticles at which normal plasmon resonance wavelength shows a sensitivity of approximately 100 nm/RIU in respect to the substrate refractive index change. “SiO2-Ag and hollow core Ag nanoparticles on silicon” are optimized to exhibit a strong normal plasmon resonance at λ = 633 nm while preserving the plasmonic field enhancement intact. Finally, a three dimensional substrate for surface-enhanced Raman spectroscopy (SERS) is designed and numerically investigated. The substrate is composed of Si nanorod array decorated with the designed nanoparticles which exhibits superior characteristics such as a uniform and gapless field enhancement and an electromagnetic enhancement factor of more than 3 × 106, an order of magnitude higher than the enhancement factor for a similar structure decorated with Au nanoparticles.
Numerical analysis of planar multimode optical sensor with active nanolayer
Authors: Błahut Marek
Published: October 2020

In the paper, numerical studies of the model of an optical sensor, based on interference of modes in a planar one-dimensional step-index configuration, are presented. Calculations are performed using the method of mode field analysis. The structure consists of the single-mode input waveguide, the multimode waveguide that guides only a few modes and the single-mode output waveguide. The structure is covered by a nanometer active sensor layer of a high refractive index, which changes its optical properties in contact with the measured external surrounding. The refractive index variation of an active sensor layer affects the modal properties of the multimode waveguide and the output optical field distribution. By the proper selection of the active layer, the considered configuration can be used for gas detection.
Complex trapezoid grating for light trapping in thin-film solar cells: super-fine structure
Authors: Junfei Fang  , Yuchun Gou  , Jianping Deng
Published: October 2020

The research of the optimal surface structure has attracted considerable interest because of its potential application in light trapping in thin-film solar cells (TFSCs). In this paper, a super-fine structure named complex trapezoid grating is proposed to improve the optical absorption comparing to the conventional simple trapezoid grating in a-Si:H TFSCs. The numerical calculation by utilizing rigorous coupled-wave analysis (RCWA) is conducted to obtain the optical absorption of the structured surface. The results demonstrate that, compared to a planar slab, the optimized-simple trapezoid grating shows 97% enhancement of power conversion efficiency η while the complex trapezoid grating shows 131% enhancement. Obviously, the complex trapezoid grating exhibits a better performance than the simple grating, which is due to the perfect antireflective effect and microcavity resonance effect. The angular response of the optical absorption in a-Si:H TFSCs was also investigated. The results further indicate that it is a better way to select the complex trapezoid grating in improving the optical absorption of silicon-based TFSCs.

Published: October 2020

Thin and lightweight achromatic focusing elements with F-number close to 1 are desirable in many practical applications. We present the idea to use diffractive structures designed to work for the substantially increased THz frequency range. The paper analyses mono- and multi-focal lenses forming point-like foci as well as axicon and light sword optical elements focusing THz radiation into line segments located along the optical axis. We consider diffractive elements in a form of the first and the second order kinoforms having various thicknesses. Designed and fabricated elements were numerically and experimentally examined to verify their achromatic functioning. We present point spread functions (XY scans) and 2D energy maps (XZ scans) for different THz frequencies. Moreover, a diagram of chromatic aberration is created by registering energy distribution along the optical axis for different frequencies. The distance corresponding to the highest energy is chosen for each frequency. Therefore, we can compare broadband working of designed structures. The spherical lens coded as kinoform of the second order provides the best broadband functioning, however it is two times thicker than structures providing extended depth of focus (light sword and axicon) working with slightly smaller efficiency but being much thinner.

Published: October 2020

The analysis of indicators that reflect changes in the social, economic and political spheres in recent years has shown their significant deterioration and the possibility of growing social tensions in the regions of Ukraine. The purpose of the study is to classify the regions of Ukraine according to the level of formation of social tensions and to determine anticipative measures aimed at preventing the creation of crisis situations. The article proposes a methodical approach to the classification of regions using the methods of cluster, discriminant analysis and analysis of variance according to the level of social tension, which includes two main stages: substantiation of the system of socio-economic indicators characterizing the level of social tension; selection and substantiation of models of classification of the regions. Within the first stage of the methodical approach the system of indicators which reflect changes in social, economic and political spheres of Ukraine in modern transformational conditions was constructed. Within the framework of the second stage of the methodical approach on the basis of cluster analysis the classification of regions according to the level of formation of social tension was carried out. The classes of regions were selected: with a low level of formation of social tension; with an intensified level of formation of social tension; with a high level of formation of social tension. The results of the study showed that the number of regions in the class with a high level of social tension is constantly growing and, unfortunately, the number of regions with high socio-economic development is decreasing. The classification of regions made it possible to determine the list of preventive measures that can reduce the losses of the state associated with the containment of possible crises in the social sphere. However, the article also states that such a list of activities should take into account the specifics of the region that is part of each class

Tetracyclic and benzannulated derivatives with a varying number and sequence of sulfur and nitrogen heteroatoms were synthesized in multistep synthetic routes. A Buchwald–Hartwig amination of brominated precursors, thermolysis of azide precursors, and a Cadogan reaction of nitro-substituted precursors were successfully applied to eventually build-up pyrrole rings to stable and soluble fused systems. The various obtained heteroatom sequences ‘SSNS’ (SN4), ‘SNNS’ (SN4’’), and ‘NSSN’ (SN4’) allowed for evaluation of structure–property relationships relative to the sulfur analogue tetrathienoacene (‘SSSS’). In line with the results for the whole series of S,N-heteroacenes, we find that replacement of sulfur by nitrogen atoms in the tetra- and hexacyclic systems leads to a red-shift in absorption, a decrease in oxidation potential and energy gap. On the other hand, the replacement of a thiophene ring by benzene leads to the opposite effects.

Bu çalışmada,
KKTC’de görev yapan özel eğitim öğretmenlerinin görüşlerine göre okullardaki
kaynaştırma uygulamalarının değerlendirilmesi amaçlanmıştır. Araştırma nitel
araştırma yöntemlerinden olgu bilim deseninde ve görüşme tekniğinde
tasarlanmıştır. Araştırmanın çalışma grubunu 17 özel eğitim öğretmeni
oluşturmaktadır. Veriler içerik analizi ile çözümlenmiştir. Araştırmada, KKTC
MEB bünyesinde yasal ve yönetsel eksikliklerden kaynaklı sorunlar bulunduğu sonucuna
ulaşılmıştır. Kaynaştırma uygulamalarında yaşanılan sorunların çözümü sadece
yasal düzenlemelerle üstesinden gelinebilecek kadar basit bir sorun olmanın
ötesinde bir sistem sorunu olduğu ortaya konulmuştur. Yönetsel süreçlerde
görülen eksiklikler tüm kaynaştırma uygulamalarını etkilemektedir. Bu durum, kaynaştırma
öğrencisinin akademik ve sosyal gelişimini de engellemekte ve istenilen
bütünleştirme hedeflerine ulaşmada yavaşlatıcı rol oynadığı sonucuna
ulaşılmıştır. Araştırmada öne çıkan bir başka sonuç ise, kaynaştırma
uygulamalarına ilişkin yaşanılan problemlerin kaynağı olarak sosyal ve kültürel
bağlamın etkili olması ve bu durumun kaynaştırma öğrencisinin duygu dünyasında
derin çalkantılara yol açmasıdır. Bu bağlamda, kaynaştırma ile ilgili tüm
paydaşların empati, bilgi ve farkındalık düzeylerinin artırılması gerektiği sonucuna
ulaşılmıştır. Buna ilaveten, normal gelişim gösteren öğrencilerin bu
bütünleşmede olumlu tutum ve davranışlar sergilemelerine katkı sağladığının
altı çizilmiştir. Bir diğer sonuç ise, kaynaştırma politikalarında gelişmiş
ülke eğitim sistemlerindeki standart ve kaliteye ulaşmak için başta eğitimde
üst düzey karar vericilerden, eğitim yöneticilerine, öğretmenlerden öğrenci ve
velilere kadar tüm paydaşların koordineli ve planlı bir şekilde sorumluluk
almaları gerektiğidir. Ayrıca, yaşanılan güçlüklerin üstesinden gelebilmek için
akademik başarıya odaklanmak yerine, bireysel farklılıkları gözeten
yaklaşımları öne çıkarmak ve paydaşlara destek olmak için teknolojiden, yapay
zekâ ve robotik uygulamalardan yararlanılmasının altı çizilmiştir. Araştırma, okul
örgütlerindeki kaynaştırma uygulamalarının eğitsel ve yönetsel analizi
açısından önem arz etmektedir.
Enhancing In Situ Observation with the SCI Design (Shadowing–Conversations–Interview to the Double) to Capture the Cognitive Underpinnings of Action
Authors: Théron Christelle
Published: October 2020

In situ observation methods have essentially been mobilized to study actors’ doings, but they have also been mobilized (through studies in the stream of situated action) to study cognition in these same organizational actors. The existing methodological designs have helped to enhance our knowledge of certain cognitive underpinnings, but they carry two limits: (1) they are deployed following a stacking logic, that is, by triangulation, which is more about compensating for the weaknesses of the component methods than uniting their strengths, and which has the pitfall of capturing cognition and action separately; and (2) they cannot capture all the situated and structuring facets of the cognitive underpinnings of action. Here we propose to overcome these barriers with the SCI design: S for shadowing, C for conversions, and I for an interview borrowing on the ‘interview to the double’ technique. This design is built in a synergy-guided effort that hinges on tightly meshing these three techniques together at fieldwork deployment. This articulation makes it possible to capture action and cognition together and to surface both the situated and structuring facets of cognition underpinning action. The SCI design is easy enough to deploy in fieldwork across a whole range of research settings.
Observing to Coproduce a Collective Narrative: Emplotment of Multiple Parallel Stories
Authors: Arnoud Justine , Peton Hélène
Published: October 2020

Observation captures complex organizational phenomena in situ. The literature on this method explains the possible data collection methods but says less about the use and organization of the data collected. As a result, the question of the meaning of observation data remains open. This article explores that question with the focus on a specific form of observation, dynamic observation, which can grasp indeterminate situations whose meaning is elusive for both practitioners and the researcher. Drawing on the work of Ricœur, we propose a conceptual tool kit founded on mimesis. We show that organizing observation data into a plot and narrative, through an inquiry conducted by researchers and practitioners together, can shed light both on the observation data and the situation observed. We embody our method by applying this tool kit to a dynamic observation conducted in a high-risk industry. We discuss the methodological issues of this co-construction of shared meaning and its role in restoring centrality to observation in the management sciences, and resituating the situations and the actors as core concerns.
Multi-Shadowing: A Gateway to Organizing? The Case of Hunting with Hounds

Organizations can be approached both as entities and as constantly evolving phenomena. The former are associated with the term ‘organization,’ while the latter are specifically associated with ‘organizing.’ In the second meaning, organizations, such as constantly evolving flows, can make observation problematic. Three of these problems deserve special attention. Many events take place at the same time, which poses a challenge for observation. Then there is a question of what to observe, especially for the researcher outside the organization. And finally, the coordination between the actors is not always directly observable. This paper shows how observation by means of multiple- researcher shadowing (Czarniawska, 2007) or ‘multi-shadowing’ makes it possible for the observer to tackle these three difficulties. For the observer, shadowing (McDonald, 2005; Mintzberg, 1970) involves physically following the actors of the organization as part of a weak or even nonparticipating observational approach. ‘Multi-shadowing’ combines simultaneous instances of shadowing different actors in the same unit of time but not of place. We compare shadowing and multi-shadowing with other approaches of solo and multiple-researcher observation. Then, we show the interest and the limits of using multi-shadowing to observe hunting with hounds, which involves activities that, while traditional, borrow a number of characteristics from modern organizations if considered through the prism of organizing.
A Critical Study of the Designation of Chapter as Ti by Asante – Twi Bible Readers

Published: October 2020

Bible reading is one of the purposeful activities Christians and users of the Bible engage in it to learn the word of God as well as learning new vocabularies of their native language, especially when they read in their mother-tongue. Asante-Twi Bible readers and users have designated ti for “chapter” in the reading of the Asante-Twi Bible. However, this does not carry the literal meaning of the text; thereby, not helping Asante-Twi Bible users to access the literal and right meaning for “chapter” in the Asante-Twi language. Using the analytical method in reading, this article argues that Asante-Twi Bible users should read chapter as ɔfa, for it carries the literal meaning of the text. Aside helping Asante-Twi Bible users to identify and ascertain the meaning of “chapter” in their language, which builds their vocabulary, it helps them to get the literal and right meaning of the text. The designation of ɔfa for “chapter” by Asante-Twi Bible users and readers keeps them from the “shock of recognition” of carrying a different meaning; it carries the literal and right meaning for “chapter” in the Asante-Twi language. This study has thus added an Akan meaning and translation of “chapter” to the knowledge of Bible reading in Akan, in general, and the Asante-Twi Bible reading communities, in particular. It is being recommended that Asante-Twi Bible users and readers should designate “chapter” as ɔfa in Bible reading which is done either silently or aloud at church, in their homes, or where ever, especially during church services, family devotions, or wherever, for academic and or spiritual purposes.
