Understanding the unexpected effect of frequency on the kinetics of a covalent reaction under ball-milling conditions
Authors: Belenguer Ana M , Michalchuk Adam A L , Lampronti Giulio I , Sanders Jeremy K M
Published: June 2019

We here explore how ball-mill-grinding frequency affects the kinetics of a disulfide exchange reaction. Our kinetic data show that the reaction progress is similar at all the frequencies studied (15–30 Hz), including a significant induction time before the nucleation and growth process starts. This indicates that to start the reaction an initial energy accumulation is necessary. Other than mixing, the energy supplied by the mechanical treatment has two effects: (i) reducing the crystal size and (ii) creating defects in the structure. The crystal-breaking process is likely to be dominant at first becoming less important later in the process when the energy supplied is stored at the molecular level as local crystal defects. This accumulation is taken here to be the rate-determining step. We suggest that the local defects accumulate preferentially at or near the crystal surface. Since the total area increases exponentially when the crystal size is reduced by the crystal-breaking process, this can further explain the exponential dependence of the onset time on the milling frequency.
Kattobase: The linguistic structure of Japanese baseball chants
Authors: Ito Junko , Kubozono Haruo , Mester Armin , Tanaka Shin'ichi
Published: June 2019

On the basis of extensive research, Tanaka (2008) develops a thorough and insightful analysis of Japanese baseball chants of the form                                                   kat   to   ba   se                 X  -  X   -  X                                                       "let it fly, hit a homerun, X-X-X!"where "X-X-X" is a rhythmic adaptation of a batter's name (e.g., Kakefu (掛布) > kaa-kee-fuu). The system is of surprising complexity since the kind of rhythmic adaptation a name receives depends in an intricate way on its length. Tanaka shows that a set of three rules is necessary where, for example, the rhythmic alignment of the right edge of the input sometimes targets the last mora (i), sometimes the last syllable of the input (ii, iii):(i) up to 3 moras: Etoo (江藤)>ee-too-oo, *ee-ee-too, Baasu (Bass)>baa-aa-suu, *baa-suu-uu(ii) 4 moras: Kiyohara (清原)>kii-yoha-raa, *kiyo-haa-raa, Ichiroo (イチロー)>ii-chii-roo, *ii-chiro-oo(iii) 5 moras and more: Makudonarudo (MacDonald)>makudo-naru-doo, *maku-donaru-doo, Oosutin (Austin)>oo-osu-tin, *oo-suu-tin, *oo-suti-nnThis paper develops a new analysis within Optimality Theory where the three distinct patterns emerge from a single and unified set of ranked and violable constraints: Depending on the length of the input, different input-output mappings are selected as optimal.Tanaka, Shin'ichi. 2008.

Vowel Quality Cues to Variable Nasal Adaptation in Mandarin Loanword Phonology
Authors: Huang Ho-Hsin , Lin Yen-Hwei
Published: June 2019

Variation in phonological adaptation has not always been analysed in detail, but some studies on Standard Mandarin (SM) loanword phonology, where a seemingly wide range of variation is present, have started to uncover cases where instances of variable adaptation are contextually conditioned (e.g. Hsieh, Kenstowicz, & Mou, 2009 on SM nasal codas; Lin 2008 on SM vowels). Our study presents corpus and experimental data in which intervocalic English nasals are variably adapted as either geminates or singletons in SM. We argue that the perceived duration and nasalization of the English prenasal vowels condition which variant is preferred in SM, and suggest how these vowel quality cues are processed and mapped onto SM phonological representation by monolingual and bilingual SM speakers. This study contributes to a better understanding of which phonetic cues modulate variation in adapted forms and how they do so.  It also showcases multiple sources for variable loanword adaptation: linguistic contexts, auditory vs. non-auditory inputs, and monolingual vs. bilingual differences.
Neural Underpinnings of Phonotactic Rule Learning
Authors: Avcu Enes , Rhodes Ryan , Hestvik Arild
Published: June 2019

This study used behavioral measures and ERP difference waves to measure the underlying brain processes during the categorization of grammatical vs ungrammatical stimuli according to a lab learned phonotactic rule. The results show that participants learned the simple rule at the behavioral level (as measured with d-prime, a sensitivity measure to rule violations). This rule learning is also reflected in the brain response to violations of the rule, which is indexed by the P3 rare-minus-frequent difference waveform. The neural results indicate that this learning took the form of a neural commitment. Participants learned the rule and used it to make active predictions, categorizing words as ungrammatical at the exact point of violation. This ability must be instantiated at the neural level, meaning rapid neural tuning has occurred in this lab setting.
The role of music in documenting phonological grammar: Two case studies from West Africa
Authors: McPherson Laura
Published: June 2019

Though the study of metrics and poetic verse has long informed phonological theory, studies of musical adaptation remain on the fringe of linguistic theory. In this paper, I argue that musical adaptation provides a unique window in speakers’ knowledge of their phonological system, which can provide crucial evidence for phonological theory. I draw on two case studies from my fieldwork in West Africa: tonal textsetting of sung folk music in Tommo So (Dogon, Mali) and the balafon surrogate language in Seenku (Mande, Burkina Faso). I show how results of these studies provide evidence for different levels of phonological grammar, the phonetics-phonology interface, and incomplete application of grammatical tone. Further, the case of the balafon surrogate language shows how studying music can be a valuable tool in language documentation and phonological description. Finally, preliminary study of Seenku tonal textsetting suggests important differences in the level of phonological encoding in vocal music vs. instrumental surrogate speech.
A Segment-specific Metric for Quantifying Participation in Harmony
Authors: Ozburn Avery
Published: June 2019

Despite substantial phonological research into segmental co-occurrence patterns, there is currently no systematic way of calculating the gradient degree to which a segment participates in a harmony system, across its co-occurrences with all other segments. In this paper, I adopt the statistical concept of relative risk as a measure of participation in harmony. I compute both O/E values and the relative risk measure for vowels in corpora of three languages with front/back harmony: Chuvash, Tatar, and Mari. I show that relative risk corresponds to the intuitive notion of how much a vowel participates in harmony, viewed based on how regularly it occurs in disharmonic contexts. I then consider the implications of the results, given what is known about categorical trends of participation in front/back harmony systems in other languages. For example, the relative risk values show that [i] generally participates less in the harmony system than most other vowels in all of these languages, and that marked vowels are typically highly harmonic. As such, this measure can illuminate gradient language-internal and cross-linguistic patterns in harmony participation that are not apparent from more categorical descriptions or entirely clear from O/E values.
The disambiguating effects of phonological exceptions in grammar
Authors: Hout Katherine
Published: June 2019

This paper explores the analytical and typological consequences of lexically-indexed constraints in Optimality Theory; namely, that the introduction of an indexed constraint by an exception can force the determination of otherwise unspecified rankings in the grammar. This “disambiguating” effect makes two important predictions. First, the typology of exceptional blocking is more complex than has been traditionally assumed: in addition to typical non-undergoing (=faithfulness-obeying) exceptions, exceptions that block a regular repair but undergo an alternative instead (referred to here as “walljumping” exceptions) are also predicted to exist. Second, the forced determination effect means that the existence of an exception determines the possibility or impossibility of other exceptional and regular patterns in the grammar. Using two exceptions to the hiatus resolution conspiracy in Mushunguli (Somali Chizigula, ISO [xma]) as a test case, I show that these predictions hold true, and demonstrate that indexed constraints allow for a unified analysis of hiatus resolution in the language. This result builds upon and strengthens prior observations made by Ito & Mester (1995) regarding the behavior of stratal faithfulness constraints, and supports a view of exceptions as clarifying and reifying agents within the grammar.
Minimality and Onset Conditions Interact with Vowel Harmony in Fungwa
Authors: Akinbo Samuel
Published: June 2019

This paper explores how the domain of vowel harmony can be affected by conditions involving minimality and the requirement for an onset within optimality theory (OT) framework. This work is based on the description and analysis of vowel harmony in Fungwa, an endangered Kainji, Benue-Congo (Niger state, Nigeria) language. In Fungwa, the root vowels trigger backness harmony which targets the vowels of onsetful prefixes and clitics. However, this harmony does not target vowels of onsetless prefixes. In this work, I argue that prosodic word (PWd) is the domain vowel harmony, a minimality condition and an onset condition. The vowel of the onsetful prefixes and clitics undergoing harmony is as a result of the minimality condition which dictates the occurence of the onsetful prefixes and clitics in the PWd. However, the onset condition on PWd results in the misalignment of the onsetless prefixes with the PWd, which is the domain of harmony.
Motivations for Consonant Epenthesis in Nonstandard Suffixed Forms of Korean Nouns
Authors: Kim Ji Yea
Published: June 2019

This paper investigates variation in the treatment of consonant clusters in stem-final position in Korean nouns. Consonant clusters undergo obligatory simplification when nouns are in isolation (e.g., /talk/ [tak] ‘chicken’). Consonant deletion may also occur in nonstandard Korean when a vowel-initial suffix is attached to nouns (e.g., /talk/ [ta.ki] ‘chicken-nom’). Another nonstandard variant discussed in this study is the suffixed forms of nouns with consonant epenthesis—particularly with [s]-epenthesis (e.g., /talk-i/ [tak.si] ‘chicken-nom’). The epenthetic consonant has received little or no attention, or neglected as a speech error in previous research. However, results from a production experiment show that [s]-epenthesis occurs consistently in terms of its position and quality. I propose this is motivated by the Base identity effect required both at the segmental and suprasegmental levels. In addition, the quality of the epenthetic consonant is also consistent: that is, only [s] but not any other consonant is epenthesized. I ascribe this to the frequency effects by which speakers epenthesize a consonant that is frequent in onset position overall in Korean.
Evidence for Gradient Input Features from Sino-Japanese Compound Accent
Authors: Rosen Eric Robert
Published: June 2019

This paper argues that pitch accent patterns of two-member Sino-Japanese compounds, hitherto considered unpredictable, can be strongly predicted by positing gradiently-valued accent features in the input, in the framework of Gradient Symbolic Computation "GSC", (Smolensky and Goldrick 2016). A simple machine-learning algorithm finds accent-affecting propensities = activations that collectively work for a set of compounds with frequently-occurring morphemes from the NHK corpus. I show that gradient input representations are needed to explain these kinds of phenomena. Examining a set of examples in which switches of morpheme order can change the accent pattern in ways that prosody cannot account for, I show that such phenomena can be explained by GSC but not by systems that have discrete-valued inputs and weighted, lexically-indexed constraints, thus providing evidence in favour of the GSC framework.

THE RELATIONSHIP BETWEEN E-LEARNING SERVICE AND STUDENT SATISFACTION A CASE STUDY AT THE SYRIAN VIRTUAL UNIVERSITY (SVU)
Authors: Ghassan Al Azmeh Salma
Published: June 2019

Purpose – This study aims at exploring the impact of electronic services provided by the Syrian Virtual University (SVU) on student satisfaction. Besides, this study seeks to determine the dimensions of both electronic services and customer satisfaction at the SVU, and to what extent these dimensions may vary in accordance with different personal characteristics among students. Research methodology – A quantitative research method was adopted using an online questionnaire to collect data from students registering in different SVU programs. Findings – Overall, results were analysed using the SPSS: 18. The results indicated that the relationship between all electronic services dimensions and student satisfaction at the SVU were positively significant except for the bulk SMS dimension. Electronic service dimensions are also all applied throughout the SVU (SMS- Web Request- Facebook- email- Electronic library- Website- Learning Management System) respectively. Besides, results show that neither electronic services dimensions nor satisfaction dimensions vary with regards to gender, speciality and age. Furthermore, satisfaction dimensions such as privacy and security – ease of use – order fulfilment – customer service – electronic service portfolio are all applied in the SVU. Research limitations – The study in this paper is limited to only one university since the Syrian Virtual University is the only virtual university in Syria. Also, the study focused only on university’s students, and not it is administrative staff. Practical Implications – the results of this paper are beneficial for the SVU future and other universities attempting to provide online services. Thus, results from advice the SVU to keep their services up-to-date with the latest technological improvements, especially the university’s website. This could be achieved by making it more users friendly and ultimately improve students’ satisfaction. Moreover, the SVU should highlight the bulk SMS service weaknesses and try to use it more efficiently. Furthermore, the SVU employees could use the results of this paper to segment their current and future services provided in the future correctly taking into account the differences between gender and other demographical factors. Originality/Value – This study is one of the first studies to investigate the relationships between E-Learning services and student satisfaction in virtual environments, especially the Syrian Virtual Universities SVU. Moreover, this study investigates specific dimensions regarding both E-services and student satisfaction and brings up a reliable model for further research.
Exponentially Decaying Extended Emissions Following Short Gamma-Ray Bursts with a Possible Luminosity–E-folding Time Correlation

Published: June 2019

The origin of extended emissions following prompt emissions of short gamma-ray bursts (SGRBs) is a mystery. The long-term activity of the extended emission is responsible for promising electromagnetic counterparts to gravitational waves, thus it may be a key to uncovering the progenitor of SGRBs. We investigate the early X-ray light curves of 26 SGRBs with known redshifts observed with the X-Ray Telescope on board the Neil Gehrels Swift Observatory (Swift). We find that the exponential temporal decay model is able to describe the extended emission comprehensively, with a rest-frame e-folding time of 20–200 s. We also estimate the isotropic equivalent energies of the extended emission with the exponential decay model and of the prompt emission, and compare with those of the prompt emission. Then, it is revealed that the extended emission is 0–3 orders of magnitude less powerful than the prompt emission. We find a strong correlation between the expected maximum luminosity and e-folding time, which can be described by a power law with an index of −3.3 and whose chance probability is 8.2 × 10−6 if there is no observation bias of Swift. The exponential temporal decay may be interpreted as coming from the spin-down timescale of the rotation energy of a highly magnetized neutron star, and/or fallback accretion onto a disk surrounding a black hole with an exponentially decaying magnetic flux by magnetic reconnection.

Realizing the utility of Lyα emission to trace the evolution of the intergalactic medium (IGM) during the epoch of reionization requires deep spectroscopy across the boundary of optical and near-infrared (NIR) spectrographs at z ∼ 7.2 when Lyα emission is at ∼1 μm. Our Texas Spectroscopic Search for Lyα Emission at the End of Reionization includes 18 nights of deep spectroscopic observations using the Keck DEIMOS (optical) and MOSFIRE (NIR) spectrographs. Within this data set we observe Lyα emission from 183 photometric-redshift-selected galaxies at z = 5.5–8.3 from the Cosmic Assembly Near infrared Deep Extragalactic Legacy Survey. Our overlapping MOSFIRE observations, over 84 galaxies in total, provide the deepest NIR spectroscopic data yet obtained for Lyα from galaxies z > 7, with >16 hr integration time for four observed galaxies. Here we analyze these four targets, and we report the discovery of a new z = 7.60 Lyα detection as well as provide an updated observation of the previously confirmed z = 7.51 Lyα emission from Finkelstein et al. with a ∼3× longer exposure time. Our analysis of these Lyα emission-line profiles reveals a significant asymmetric shape. The detection of Lyα from two out of three bright sources (M
UV < −20.25) could imply that these bright galaxies inhabit ionized bubbles in a partially neutral IGM, although deeper exposures may reveal Lyα emission in the fainter source.
Coronagraphic Observations of Si x λ14301 and Fe xiii λ10747 Linearly Polarized Spectra Using the SOLARC Telescope
Authors: Dima Gabriel I. , Kuhn Jeffrey R. , Schad Thomas A.
Published: June 2019

The forbidden Si x emission line at 14301 Å has been identified as a potentially valuable polarized diagnostic for solar coronal magnetic fields; however, the only polarized Si x measurements achieved to date have been during eclipses and at comparatively low spatial and spectral resolution. Here we report spectropolarimetric observations of both the Si x 14301 Å and more well-established Fe xiii 10747 Å coronal lines acquired with the 0.45 m aperture SOLARC coronagraph atop Haleakalā. Using its fiber-based integral field spectropolarimeter, we derive observations sampled at radial intervals of 0.05

 (i.e., ∼50″) with a spectral resolving power of ≈36,000. Results for both lines, which represent averages over different active and nonactive regions of the corona, indicate a relatively flat radial variation for the line widths and line centers and a factor of ≈2–3 decrease in polarized brightness between 1.05 and 1.45

. Averaging over all the measurements the mean and standard deviations of line properties for Si x 14301 Å and Fe xiii 10747 Å are, respectively, FWHM of 3.0 ± 0.4 Å and 1.6 ± 0.1 Å, line-integrated polarized brightness of 0.07 ± 0.03 and 0.3 ± 0.3 erg s−2 cm−2 sr−1, where the uncertainty quoted reflects a large sample variance, and line center wavelengths 14300.7 ± 0.2 Å and 10746.3 ± 0.1 Å. The polarized brightness for both lines may be underestimated by up to a factor of 5 due to limitations in the photometric calibration. When accounting for this uncertainty we find consistency between our observations and previous measurements of the two lines as well as theoretical calculations and affirm the potential of the Si x line as a polarized diagnostic of the solar corona.

Observations have revealed massive (

) galaxies that were already dead when the universe was only ∼2 Gyr. Given the short time before these galaxies were quenched, their past histories and quenching mechanism(s) are of particular interest. In this paper, we study star formation histories (SFHs) of 24 massive galaxies at 1.6 < z < 2.5. A deep slitless spectroscopy and imaging data set collected from multiple Hubble Space Telescope surveys allows robust determination of their spectral energy distributions and SFHs with no functional assumption on their forms. We find that most of our massive galaxies had formed >50% of their extant masses by ∼1.5 Gyr before the time of observed redshifts, with a trend where more massive galaxies form earlier. Their stellar-phase metallicities are already compatible with those of local early-type galaxies, with a median value of

and scatter of ∼0.15 dex. In combination with the reconstructed SFHs, we reveal their rapid metallicity evolution from z ∼ 5.5 to ∼2.2 at a rate of ∼0.2 dex Gyr−1 in

. Interestingly, the inferred stellar-phase metallicities are, when compared at half-mass time, ∼0.25 dex higher than observed gas-phase metallicities of star-forming galaxies. While systematic uncertainties remain, this may imply that these quenched galaxies have continued low-level star formation, rather than abruptly terminating their star formation activity, and kept enhancing their metallicity until recently.
Constraining Compact Object Formation with 2M0521
Authors: Breivik Katelyn , Chatterjee Sourav , Andrews Jeff J.
Published: June 2019

We show that the recently discovered binary 2M05215658+4359220 (2M0521), comprising a giant star (GS) orbiting a suspected black hole (BH) in an ∼80 day orbit, may be instrumental in shedding light on uncertain BH-formation physics and can be a test case for studying wind accretion models. Using binary population synthesis with a realistic prescription for the star formation history and metallicity evolution of the Milky Way, we analyze the evolution of binaries containing compact objects (COs) in orbit around GSs with properties that are similar to 2M0521. We find ∼102–103 CO–GS binaries in the Milky Way observable by Gaia and 0–12 BH–GS and 0–1 neutron star–GS binaries in the Milky Way with properties that are similar to 2M0521. We find that all CO–GSs with P
orb < 5 yr, including 2M0521, go through a common envelope (CE), and hence form a class of higher-mass analogs to white dwarf post-CE binaries. We further show how the component masses of 2M0521-like binaries depend strongly on the supernova-engine model that we adopt. Thus, an improved measurement of the orbit of 2M0521, imminent with Gaia’s third data release, will strongly constrain its component masses and as a result inform supernova-engine models that are widely used in binary population synthesis studies. These results have widespread implications for the origins and properties of CO binaries, especially those detectable by the Laser Interferometer Gravitational-Wave Observatory and the Laser Interferometer Space Antenna. Finally, we show that the reported X-ray nondetection of 2M0521 is a challenge for wind accretion theory, making 2M0521-like CO–GS binaries a prime target for further study with accretion models.
Cosmic ray and solar activity influences on long-term variations of cave climate systems
Authors: Stoev Alexey , Stoeva Penka
Published: June 2019

During the analysis of solar activity impact on climate, the emphasis is placed on temperature changes. Earth's atmosphere is a dynamical system with a complex variability in space and time. Due to the fact that caves in Karst preserve the long term environmental changes, the investigation of the in-caves’ atmospheric parameters and their variations with time becomes very important in the last quarter of century. In this paper we investigate the temporal evolution of the temperature and pressure of the ground atmospheric layer in the region of two Bulgarian caves: Snezhanka (Pazardjik region) and Uhlovitsa (Smolyan region), during the period 2005–2017. We show that thermal and mass exchange of the caves’ air with the environment has significant temporal variations. On annual basis the thermo-dynamical parameters of the observed caves behaves as a barotropic fluid, in which the air density depends only on atmospheric pressure. As a result, the temporal evolution of in-caves’ pressure and temperature change synchronously with time. The observed 11-year signal could be attributed to the heliospheric modulation of galactic cosmic ray (GCR) intensity, which modulates the ozone and humidity near the tropopause and correspondingly the strength of the atmospheric greenhouse effect. Our study helps to clarify the influence of helio-geophysical factors on the state of the lower atmosphere.

Alors que Daech et Al-Qaïda se sont violemment affrontés au Moyen-Orient, leurs « filiales » sahéliennes ont eu tendance à s’éviter. Depuis 2017, elles ont même entamé un rapprochement et coopèrent occasionnellement. La chute de Daech en zone syro-irakienne aura des répercussions au Sahel. S’il n’est pas dit que l’État islamique au Grand Sahara (EIGS) et le Groupe de soutien à l’islam et aux musulmans (GSIM) fusionnent, il est en revanche assuré que le djihadisme perdurera dans la zone.

Cartografías postestructurales entre las prácticas alternativas en salud y las nuevas espiritualidades
Authors: Palacios Ramírez José
Published: June 2019

La articulación de viejas y reinventadas espiritualidades con prácticas alternativas ligadas a la salud, constituye una pieza clave para abordar las transformaciones culturales en las formas de vida actuales. Este trabajo es esencialmente una propuesta de reflexión teórica, aunque se apoya en la presentación de algunos aspectos incidentales extraídos de procesos etnográficos desarrollados durante los últimos años, que muestran claramente el carácter ubicuo, difuso y elusivo de estas prácticas, especialmente cuando se trata de elaborar miradas explicativas de conjunto. La idea central de estas reflexiones será básicamente: ¿qué podemos aprender de esta fragmentariedad?, ¿qué ocurre con los aspectos de estas nuevas articulaciones diseminados en otros tipos de prácticas? Con base en esto, trataremos de delimitar los principales perfiles y problemáticas que ofrece este complejo e interesante objeto antropológico de reflexión, apoyándonos en propuestas conceptuales posestructuralistas.
Los primeros gimnasios higiénicos: espacios para sanar y corregir el cuerpo
Authors: Vicente-Pedraz Miguel , Torrebadella-Flix Xavier
Published: June 2019

Los primeros gimnasios higiénicos, fundados en la década de los años sesenta del siglo XIX, constituyeron un efectivo respaldo a una cultura corporal que, particularmente en Cataluña, empezaba a ofrecer elocuentes signos de diferenciación social entre los miembros de la burguesía. Las reciprocidades ideológicas y culturales que mantenían los usuarios del gimnasio sirvieron de caldo de cultivo para la propagación de las emergentes prácticas y discursos, tanto higiénicos y terapéuticos como de autodominio y de esparcimiento, los cuales, basados en la ejercitación física, supondrían un importante dispositivo para la afirmación de clase. Mediante cotejo documental acometemos un análisis de corte socio-crítico. Concluimos que la actividad de los gimnasios decimonónicos, especialmente los de Barcelona, dio lugar a una embrionaria cultura física privativa que operó como plataforma de socialización y moralización físicas de la burguesía. A la vez, establecemos conexiones entre ese proceso y la primitiva penetración del sport, reconocible sobre todo en la adecuación de los principios fundadores de este a los intereses de clase.
Deductive Data Warehouses
Authors: Rabuzin Kornelije
Published: June 2019

This chapter presents the concept of “deductive data warehouses.” Deductive data warehouses rely on deductive databases but use a data warehouse in the background instead of a database. The authors show how Datalog, as a logic programming language, can be used to perform on-line analytical processing (OLAP) analysis on data. For that purpose, a small data warehouse has been implemented. Furthermore, they propose and briefly discuss “Datalog by example” as a visual front-end tool for posing Datalog queries to deductive data warehouses.
Designing a Neural Network Model for Time Series Forecasting
Authors: Sanchéz Paola Andrea Sanchéz , González José Rafael García , Fajardo-Toro Carlos Hernán , Sánchez Paloma María Teresa Martínez
Published: June 2019

Artificial neural networks are highly flexible and efficient tools in the approximation of time series patterns. In recent years, more than 5,000 studies oriented to the use of neural networks in time series forecasting have been evidenced in the extant literature. However, the methodology used for its specification and construction still involves a lot of trial and error or is inherited from econometric and statistical procedures that do not fit perfectly to the characteristics of the time series. This is especially true when they present non-linear behavior; moreover, it is not designed for working with neural networks. The objective of this chapter is to present a five-step guide for the specification, design, and validation of a neural network model for forecasting time series.

Encryption is the process of converting confidential private data into unreadable form and securing information in the file from unauthorized access using various encryption algorithms. We live in the information age where the exchange of private information has become the integral part of our day-to-day activities. Billions of e-mails and business data are sent throughout the world through internet daily. The success of the information age is to keep private secure data from unauthorized access and key to access the private and secure data for authorized users. Encryption in this information age plays a vital role in the protecting the confidential data from unauthorized access. In the last few decades, the computer network has created a revolution in the use of information. Authorized users access their data or send their private data from anywhere in the world; hence, it has become very important to secure the private data not only where it is stored, but also to maintain high level of confidentiality while transmission of this private data from one machine to another.

The importance of valuing intellectual capital in educational organizations is to measure their contributions to society, which complement the financial landscape and allow comparison between similar institutions, in order to compare their performance. Therefore, the conclusion of carrying out this process in higher education is 1) providing adequate information on the value of HEIs to society, 2) assessing and directing the response capacity of the organization towards the needs of the productive and services sector (interest groups), 3) orienting the development of the components of intellectual capital towards a knowledge management that allows to solve in an efficient way the problems of the society, and 4) optimizing the human talent of the institution for the achievement of the organizational objectives.

Authors: Palahicky Sophia , Halcomb-Smith Lauren
Published: June 2019

Many post-secondary institutions utilize learning management systems (LMSs) to deliver online, blended, and face-to-face courses. LMSs have a wide variety of built-in functionality that can be used to facilitate innovative teaching. This chapter provides useful information, critical thinking questions, and insights that instructors can use to expand their adoption, knowledge, and usage of LMS tools to build upon innovative teaching practices. Three instructional approaches are discussed: case-based learning (CBL), scenario-based learning (SBL), and gamified learning. Additionally, specific examples are provided to demonstrate how LMS tools can be used to support CBL, SBL, and gamified learning. This chapter invites instructors to critically reflect on how they use LMSs and other educational technologies to carry out ineffective instructional strategies. Furthermore, it provides concrete examples of how LMS tools can help instructors improve their teaching practice and adopt creative instructional approaches with thoughtful use of technology grounded in sound pedagogical practices.
Instructors' Professional Learning and Implementation of Problem-Based Learning in Higher Education
Authors: Lock Jennifer , Koh Kim
Published: June 2019

Contemporary educational reform in North America, as well as other parts of the world, has led to a shift toward conceptualizing assessment, teaching, and learning for the purpose of developing students' competencies (e.g., critical thinking, complex problem-solving, creativity and innovation, collaboration). Both in K−12 schools and higher education, instructors need to adopt innovative pedagogies and assessments to support the fostering of these competencies. In this chapter, the authors report on a mixed-method study where the implementation of problem-based learning (PBL) was used in a preservice teachers' assessment course designed in a teacher preparation program at one western Canadian university. The findings acknowledge that facilitating PBL is a pedagogical shift and requires instructors to revisit their pedagogical practices and assumptions in relation to student learning and teaching. The chapter concludes with three directions for future research.

Experiential Learning Model for Online and F2F Programs in University Continuing Education
Authors: Piedra Daniel
Published: June 2019

Online learning continues to grow throughout the world of post-secondary education. However, the actual learning experience is becoming less and less about human interaction and more and more about the development of applications (“apps”) that rely more on technology than the interaction of instructor and learner. In an effort to enhance the level of student engagement, McMaster University's Centre for Continuing Education has turned to a model of online learning that leverages the benefits of experiential learning enabling students to work on authentic industry projects. The results of this one-year pilot are presented outlining the strengths, challenges, and areas for improvement and further research. While the experiential learning model received favorable reviews from learners, several areas for improvement were noted including, improving the onboarding process for both learners and instructors, redesigning courses to accommodate experiential learning, and improving the communication between corporate partners and those involved in each course.
Entering a New World

This chapter focuses on the identity work engaged in by two older Indian male entrepreneurs and their use of technology in their business enterprises. The chapter briefly outlines the concepts of older entrepreneurs and entrepreneurial innovation and gives an overview of the South African context that pertains to Indians. McClelland's theory of motivation, Bandura's theory of self-efficacy and identity theory serve as the theoretical frameworks. The author conducted interviews with two older Indian male entrepreneurs to ascertain their use of digital technology in their respective businesses. The result of the investigation indicates that older Indian males' use of digital technology is minimal and that they engage in entrepreneurial professional identity work to a minimal extent. Some recommendations are made regarding solutions to the problems identified.
Globalization, Innovation, and Marketing Philosophy
Authors: Mohanty Sandeep Kumar
Published: June 2019

Globalization has brought innovation to center stage of marketing activities. This can be related to opportunities as well as scope for consumer proficiency. Initial years of this decade have found that over dependence on innovation has made it consistent, compulsive and converging. With this impetuous innovation, certain aspect of critical thought process brings technology to the spot-light. Marketing philosophy that recognizes technology as the rationale of foundation of globalization and innovation must retrospect and further critically assess that how far technology has dissociated both the terms. Globalization by nature has been divergent, yet struggling to ensure marketing success because innovation is converging with the help of technology. Global Marketing is in a precarious juncture where every alternate day new technology is wiping out the old and with this new market is superimposing the old one. This transition is threatening concepts like segmentation, targeting and branding. This chapter is a critical assessment of role of technology in redefining the relationship between globalization, innovation and marketing. Secondary data of 51 Indian business sectors, consisting some of the leading market players have been analyzed to explore the relationship and propose a conceptual model.
Conceptualizing Corporate Entrepreneurship Capability and Its Linkages Towards Firm Performance
Authors: Kumar Rohit , Kumar Amit
Published: June 2019

The practices facilitating Corporate Entrepreneurship Capability (CEC), an intangible organizational capability embedded in an enterprise's culture are particularly important to innovation. The existing literature suggest the important of combining practices, however, there is a distinct lack of theoretical as well as empirical studies that have explored how these practices work together to promote and facilitate CEC. While different alternatives to realize the simultaneous reconciliation of exploration and exploitation have been proposed, how organizations build CEC is not fully understood. In this chapter, the authors first define CEC and then explain its relationship with Business Model Innovation (BMI), Innovation Ambidexterity (IA) and firm performance. The chapter is a theoretical contribution and builds on the Schumpeter view on entrepreneurship and innovation, resource-based theory of the firm and corporate entrepreneurship literature. The authors have suggested alternate contingency models for testing relationships among CEC, BMI, IA and Firm Performance.
