Syntactic Configuration of Code-Switching between Indonesian and English: Another Perspective on Code-Switching Phenomena

Code-switching, an alternation or mixing one language with another, has been an unmarked phenomenon for a multilingual society. In Indonesia, this phenomenon nowadays lives and thrives among the people. This study discusses the syntactic configuration of code-switching between Indonesian and English in terms of switched segments, points, and changing types. The study is descriptive qualitative in nature. The data comprise 25 recording hours of natural speech produced by 119 Indonesians in 4 types of interaction: seminars, meetings, TV dialogues, and chitchats conducted in six metropolitan cities—Jakarta, Bandung, Semarang, Yogyakarta, Surabaya, and Makassar. The sample drawn purposively comprises 550 switching discourses consisting of 666 switching corpora. It is found that nouns serving as subjects, predicators, objects of verbs, and prepositions to be the most dominant switched segments. A switch between Indonesian noun phrases and English noun phrases, Indonesian verbs or prepositions, and English objective noun phrases, Indonesian conjunctions, and English conjoined noun phrases or clauses is the most popular switched points, and intercausal switching including intraporal and interlexical switching is the most frequent switching type of code-switching between Indonesian and English. ANOVA Friedman’s test confirms that these patterns are the same among the four types of discourses, implying that such a syntactic configuration of Indonesia-English code-switching is universally applicable to any situation and type of interaction. In conclusion, the domination of nouns indicates that the syntactic configuration of Indonesian-English code-switching mainly occurs at minor constituents such as within a clause, phrase, and word boundaries. This demonstrates that code-switching between Indonesian and English is more likely to occur intrasentential rather than intersentential, which is the most popular anywhere in literature.

Recognizing Code Switching and Code Mixing in Talk Show Catatan Najwa with Maudy Ayunda on Youtube

People capable of speaking and writing two languages well are called bilingual. In contrast, the people who use two words or even in a sentence without paraphrase mean code-mixing. The purpose of this study is to know the types of code-switching and code-mixing. Code-switching and code-mixing are parts of sociolinguistics. Sociolinguistics studies an analysis of language. The linguistic factors are related to the factors beyond the language, such as language use done by its speakers in a particular speech community. Code-switching and code-mixing usually happened when talking to someone. The source of the research was the talk show Catatan Najwa with Maudy Ayunda on Najwa Shihab’s Channel Youtube. In this talk show, there was a guest star called Maudy Ayunda. She has just recently graduated from Oxford University and had a conversation with Najwa Shihab. The conversation happened on Najwa Shibah’s Youtube Channel. In this conversation, they used two languages that are Indonesian and English. This research used the qualitative descriptive method. To complete the data, The researcher also conducted library research. This study focused on video Najwa Shihab’s Channel Youtube. The research results are Inter-Sentential with 9 data as the code-switching type and Insertion with 7 data as the code-mixing type.

New Time-Varying Sliding Surface for Switching Type Quasi-Sliding Mode Control

This study considers the problem of energetical efficiency in switching type sliding mode control of discrete-time systems. The aim of this work is to reduce the quasi-sliding mode band-width and, as follows, the necessary control input, through an application of a new type of time-varying sliding hyperplane in quasi-sliding mode control of sampled time systems. Although time-varying sliding hyperplanes are well known to provide insensitivity to matched external disturbances and uncertainties of the model in the whole range of motion for continuous-time systems, their application in the discrete-time case has never been studied in detail. Therefore, this paper proposes a sliding surface, which crosses the system’s representative point at the initial step and then shifts in the state space according to the pre-generated demand profile of the sliding variable. Next, a controller for a real perturbed plant is designed so that it drives the system’s representative point to its reference position on the sliding plane in each step. Therefore, the impact of external disturbances on the system’s trajectory is minimized, which leads to a reduction of the necessary control effort. Moreover, thanks to a new reaching law applied in the reference profile generator, the sliding surface shift in each step is strictly limited and a switching type of motion occurs. Finally, under the assumption of boundedness and smoothness of continuous-time disturbance, a compensation scheme is added. It is proved that this control strategy reduces the quasi-sliding mode band-width from O(T) to O(T3) order from the very beginning of the regulation process. Moreover, it is shown that the maximum state variable errors become of O(T3) order as well. These achievements directly reduce the energy consumption in the closed-loop system, which is nowadays one of the crucial factors in control engineering.

Functional and sociocultural attitudes of code-switching and its relation to the meaning-making process: The case of dubbing Kim Possible into Arabic

Aims and objectives/purpose/research questions: The aim of this study is to investigate the sociolinguistic functions of code-switching and its relation to the meaning-making process by using the animated series Kim Possible as a case study. Design/methodology/approach: This study employs Muysken’s taxonomy to draw on code-switching patterns in lexico-grammar in relation to human behavior. The study also uses the functional approaches of Muysken and Appel and Gumperz as binary investigatory frameworks to locate interlingual and intralingual code-switching particularities and to elaborate on code-switching functions. Data and analysis: The analysis encompasses 48 episodes. Firstly, we extracted and transcribed code-switching occurrences in light of Muysken’s typology episode-by-episode and categorized them according to their code-switching type (interlingual or intralingual). Secondly, we quantified the occurrences according to their syntactic form to make more systematic claims about code-switching patterns. Next, we triangulated the patterns by examining the context of utterances and extralinguistic factors in the original series vis-à-vis the dubbed version to draw upon information beyond the structure or grammar. Findings/conclusions: The Arabic dubbed version was able to communicate the characters’ cosmopolitan diversity, which correlates with the series’ sense of linguistic modernity and humor. At the same time, the Arabic version was able to portray the extralinguistic reality of Lebanon and its multi-linguistic tapestry. Originality: This research is original because it focuses on Lebanese-Arabic, a dialect seldom discussed in the context of translation. The research also examines language variations in the context of dubbed discourse, where code-switching is integrally pertinent to visual-signs and the cultural background of characters. Significance/implications: The study recognizes the intricacy of code-switching as a reflective phenomenon of social reality and power dynamics; therefore, it contributes in the fields of translation and sociolinguistics.

Improved Synaptic Device Properties of HfAlOx Dielectric on Highly Doped Silicon Substrate by Partial Reset Process

This work demonstrates the synaptic properties of the alloy-type resistive random-access memory (RRAM). We fabricated the HfAlOx-based RRAM for a synaptic device in a neuromorphic system. The deposition of the HfAlOx film on the silicon substrate was verified by X-ray photoelectron spectroscopy (XPS) analysis. It was found that both abrupt and gradual resistive switching could be implemented, depending on the reset stop voltage. In the reset process, the current gradually decreased at weak voltage, and at strong voltage, it tended to decrease rapidly by Joule heating. The type of switching determined by the first reset process was subsequently demonstrated to be stable switching by successive set and reset processes. A gradual switching type has a much smaller on/off window than abrupt switching. In addition, retention maintained stability up to 2000 s in both switching cases. Next, the multiple current states were tested in the gradual switching case by identical pulses. Finally, we demonstrated the potentiation and depression of the Cu/HfAlOx/Si device as a synapse in an artificial neural network and confirmed that gradual resistive switching was suitable for artificial synapses, using neuromorphic system simulation.

Infliximab, Immunomodulators and Treatment Failures in Paediatric and Adolescent Patients with Crohn’s Disease: a Nationwide Cohort Study

Background and Aims In paediatric patients with Crohn’s disease, the role of combination therapy, infliximab plus immunomodulators [thiopurine or methotrexate], is debated and data are sparse. We examined whether infliximab plus immunomodulators, compared to infliximab therapy alone, reduces the risk of treatment failure measured by intestinal surgery or switching type of anti-tumour necrosis factor [TNF] α agent within 24 months. Design Using Danish registries, we identified patients with Crohn’s disease, aged ≤ 20 years at the time of the first infliximab treatment, and retrieved data on their co-medications. We used Cox regression models to examine surgery or switching type of anti-TNFα agent from January 1, 2003 to December 31, 2015. Results We included 581 patients. The 2-year cumulative percentage of surgery was 8.5% among patients receiving combination therapy and 14.5% in those receiving infliximab alone. The adjusted 2-year hazard ratio [HR] of surgeries was 0.53 (95% confidence interval [CI] 0.32–0.88) in patients receiving combination therapy, compared to patients receiving infliximab alone. When examining a switch of anti-TNFα we included 536 patients. Within 2 years, 18.3% experienced a switch among patients receiving combination therapy and 24.8% in patients treated with infliximab alone, corresponding to an adjusted HR of 0.66 [95% CI 0.45–0.97] in patients receiving combination therapy. Conclusions The HR of intestinal surgeries and the risk of a switch to another anti-TNFα was reduced in paediatric and adolescent patients receiving combination therapy, compared to patients receiving only infliximab. These results suggest a benefit for infliximab therapy combined with immunomodulators, but these need to be confirmed in data with additional clinical information.

Modelling Stick Balancing by Applying Switching-Type Control

In today’s aging society special attention is devoted to the research of human balance control. Our research group focuses on understanding the control mechanism of the brain during balancing from an engineering point of view. The model of stick balancing is derived and the dynamical behaviour of the mechanical system is investigated numerically. The control force is modelled as a PD controller with predictor feedback without implementation uncertainty, which allows perfect delay compensation. However, the sensory dead zone of human perception is also accounted for in the model and thus, a delayed switching-type controller is applied. After deriving the mechanical model, numerical analysis is carried out in order to investigate the effect of time delay and the size of sensory dead zones.
