Caractérisation des innovations managériales dans les collectivités territoriales
Authors: Cohard Philippe , Bories-Azeau Isabelle 
Published: January 2022

Incitées par des changements législatifs successifs, les collectivités territoriales sont amenées à innover pour optimiser leurs ressources et améliorer leurs services aux citoyens. Dans les collectivités territoriales, les démarches d’innovation se traduisent fréquemment par le déploiement de méthodes ou d’outils en rupture avec les usages précédents. Même si ces innovations ne représentent pas des innovations radicales, elles peuvent générer des changements importants dans le fonctionnement et dans les modes d’organisation de la collectivité. Quelles sont les caractéristiques des innovations dans les collectivités territoriales ? Cet article constitue une réponse à cette question. Au-delà, il s’agit d’identifier les objectifs poursuivis par ces collectivités et les processus à l’œuvre leur permettant d’innover. Pour cela nous avons procédé à une analyse qualitative exploratoire de 13 rapports de projets innovants réalisés dans des collectivités territoriales et des structures rattachées. La grille d’analyse réalisée prend en compte la théorie des capacités dynamiques. Les résultats permettent de proposer un modèle fondé sur les caractéristiques des innovations et montrent que les collectivités territoriales ne mobilisent pas les capacités dynamiques dans le cadre d’un processus formel.
Piperine suppresses growth and migration of human breast cancer cells through attenuation of Rac1 expression
Authors: Buranrat Benjaporn , Junking Mutita 
Published: January 2022

Objective:
To investigate the effect of piperine on human breast cancer cells.

Methods:
The effect of piperine on proliferation and migration of human breast cancer cells, MCF-7 and MDA-MB-231, was investigated using colony formation assays, wound healing assays, Matrigel migration assays, flow cytometry, RT-qPCR, and Western blotting assays.

Results:
Piperine inhibited the growth of MCF-7 and MDA-MB-231 cells and suppressed colony formation. Cell reduction at the G0/ G1 phase and cell arrest at the G2/M phase were observed in breast cancer cells. However, the significant effect was only demonstrated in MDA-MB-231 cells. Moreover, cancer cell migration was suppressed by piperine at low concentration. RT-qPCR and Western blotting assays showed that piperine downregulated Rac1 gene and protein expression.

Conclusions:
Piperine could inhibit growth and migration of breast cancer cells by reducing Rac1 gene and protein expression.
Predictors of vision following ranibizumab injection for age-related macular degeneration
Authors: Sayed Khulood M. , Moussa Elshimaa A. Mateen 
Published: January 2022

Purpose
The aim of this study was to investigate the optical coherence tomography (OCT) parameters that can predict the vision of patients with exudative age-related macular degeneration (AMD) 1 month following intravitreal ranibizumab injection.

Patients and methods
This is a prospective consecutive case-series study that was conducted on 20 eyes of 18 consecutive patients who received intravitreal ranibizumab injection for exudative AMD. A spectral-domain OCT imaging was done just before and 1 month following the injection. The main outcome measures were the correlations between the postinjection vision and the preinjection OCT parameters.

Results
A significant reduction was noted in retinal volume at the 3 and 5-mm central circles. The reduction in retinal thickness was statistically significant, while the reduction in other OCT parameters was insignificant. There was a strong correlation between postinjection vision and each of the following: foveal volume at 1 mm, full retinal thickness at the fovea, and retinal pigment epithelium elevation at the fovea (r>0.7, P<0.05). Multivariate analysis showed that the foveal volume (r
2=0.538) was the most important predictor factor for visual acuity, 1 month following ranibizumab injection.

Conclusions
Foveal volume is the most important factor for vision prediction and can be used as an early visual predictor 1 month following ranibizumab injection in patients with AMD.
On combinatorics of the Arthur trace formula, convex polytopes, and toric varieties
Authors: Asgari Mahdi , Kaveh Kiumars 
Published: January 2022

AbstractWe explicate the combinatorial/geometric ingredients of Arthur’s proof of the convergence and polynomiality, in a truncation parameter, of his noninvariant trace formula. Starting with a fan in a real, finite dimensional, vector space and a collection of functions, one for each cone in the fan, we introduce a combinatorial truncated function with respect to a polytope normal to the fan and prove the analogues of Arthur’s results on the convergence and polynomiality of the integral of this truncated function over the vector space. The convergence statements clarify the important role of certain combinatorial subsets that appear in Arthur’s work and provide a crucial partition that amounts to a so-called nearest face partition. The polynomiality statements can be thought of as far reaching extensions of the Ehrhart polynomial. Our proof of polynomiality relies on the Lawrence–Varchenko conical decomposition and readily implies an extension of the well-known combinatorial lemma of Langlands. The Khovanskii–Pukhlikov virtual polytopes are an important ingredient here. Finally, we give some geometric interpretations of our combinatorial truncation on toric varieties as a measure and a Lefschetz number.
N-colored generalized Frobenius partitions: generalized Kolitsch identities
Authors: Aygin Zafer Selcuk , Nguyen Khoa D. 
Published: January 2022

AbstractLet
$N\geq 1$
be squarefree with
$(N,6)=1$
. Let
$c\phi _N(n)$
denote the number of N-colored generalized Frobenius partitions of n introduced by Andrews in 1984, and
$P(n)$
denote the number of partitions of n. We prove
$$ \begin{align*}c\phi_N(n)= \sum_{d \mid N} N/d \cdot P\left( \frac{ N}{d^2}n - \frac{N^2-d^2}{24d^2} \right) + b(n),\end{align*} $$
where
$C(z) := (q;q)^N_\infty \sum _{n=1}^{\infty } b(n) q^n$
is a cusp form in
$S_{(N-1)/2} (\Gamma _0(N),\chi _N)$
. This extends and strengthens earlier results of Kolitsch and Chan–Wang–Yan treating the case when N is a prime. As an immediate application, we obtain an asymptotic formula for
$c\phi _N(n)$
in terms of the classical partition function
$P(n)$

Oral hygiene status, interdental cleaning and perception of gingival bleeding among a group of pregnant women in Nigeria
Authors: SOROYE Modupeoluwa Omotunde , ONIGBINDE Olubunmi Omotunde 
Published: January 2022

Background: Hormonal and vascular changes in pregnancy can lead to exaggeration of inflammatory response to local irritants like dental plaque causing pregnancy gingivitis which if not treated can result in advanced periodontal diseases and consequent adverse pregnancy outcomes.
Objective: To assess the oral hygiene and gingival bleeding perception of pregnant women
Methods: Self-administered questionnaires were used to collect data. Oral hygiene status and gingival status were assessed with Simplified Oral Hygiene Index (OHI-S) and gingival bleeding index respectively. Data was analysed using IBM SPSS (Statistical Package for the Social Sciences) version 25. Results were presented in frequency and percentages and chi square analysis done for the categorical variables with statistical significance set at P < 0.05.
Results: One hundred and fifty-one participants with age range of 20 to 43 years with a mean age of 29.85±4.05years participated in the study. All participants used toothbrush to clean their teeth and 44.4% used medium bristled toothbrush. Two-third used herbal toothpaste. More than two-thirds (84.1%) of the participants used both horizontal and vertical tooth brushing technique. Only 33.8% brushed twice daily. Though 92.1% claimed to clean interdentally, only 19.4% used dental floss. Prevalence of gingival bleeding was 31.8%. Two persons (1.3%) thought it normal to bleed from the gum while brushing and 86.8% did not know one can bleed from the gum during pregnancy Forty-four (29.1%) and 18(11.9%) of participants had fair and poor oral hygiene status respectively. 55.6% bled on probing and had gingival bleeding index of 1 and 2. Four (2.6%) of participants had gingival recession measuring 3mm to 4mm and 8.6% had halitosis. Statistical analysis of the association between participants’ perception of gum bleeding and oral hygiene status showed statistical significance.
Conclusion: The knowledge of pregnancy gingivitis is poor among the participants. There is the need to educate them about this and incorporate periodontal care into antenatal care so as to increase their quality of life during pregnancy.
Prevalence of Incidental Dental Anomalies seen on Pre-Treatment Digital Panoramic Radiographs of a Group of Nigerian Orthodontic Patients: A Retrospective Study
Authors: AIKINS Elfleda Angelina , UTUTU Chinyere , CHUKWUMA Emmanuel Ifeanyi 
Published: January 2022

Background: Radiographs are used by orthodontists in the diagnosis of malocclusion, treatment planning and monitoring. These usually reveal presence of dental anomalies that may require further assessment and management.
Objective: To investigate the prevalence, types and distribution of dental anomalies seen on the orthopantomograms (OPGs) of orthodontic patients at the University of Port-Harcourt Teaching Hospital (UPTH).
Methods: This was a retrospective cross-sectional radiographic study of a cohort of orthodontic patients who presented to the Department of Child Dental Health, University of Port Harcourt Teaching Hospital, Rivers State, Nigeria. The data gathered from digital orthopantomograms of the patients was analysed using IBM Statistical Package for Social Sciences (SPSS) Statistics for Windows version 25.0.
Results: The study comprised 249 patients with an age range of 5-44years (mean age of 14.6±7.7years) comprising 108 (43.4%) males and 141 (56.6%) females. Seventy (28.1%) [(29, 41.4% males), (41, 58.6% females)] of the patients had at least one dental anomaly. Dental anomalies were commonest (48, 68.6%) within 10-19 years age bracket followed by the 0-9 years age bracket (11, 15.7%). The most frequent dental anomaly was taurodontism (43, 61.4%), followed by congenitally missing teeth (8, 11.4%), supernumerary teeth (5, 7.1%), odontoma (4, 5.7%), peg shaped lateral incisors and transposition (2, 2.9%) respectively. Dental anomalies were more frequent in the maxilla (43, 61.4%).
Conclusion: The most common dental anomaly was taurodontism. Anomalies were more frequent in female than male patients and in the maxilla than in the mandible.
Choosing the Best Social Media Influencer: The role of gender, age, and product type in influencer marketing.
Authors: Al-Shehri Mohammed 
Published: January 2022

Introduction: Social media has created a new type of celebrity form (influencers), which is defined as people who are famous on social media and have many followers. Companies currently depend on influencers to send their marketing messages to the audience, and to increase the marketing ROI, it is important to target the right influencers.
Purpose: This research focused on social media influencers’ impact on consumer purchase intent and showed whether gender difference of consumers or influencers had any effect on those decisions. The research also included the age of consumers and the product type to know if they had any effect.
Methodology: Qualitative and quantitative methods were used to obtain the required information; two focus groups were conducted to get the names of 80 influencers, and an online questionnaire was used to collect the data, formula of the sample size by Krejcie and Morgan (1970 as cited by Kasomo, 2001) was used to determine study sample of 387 respondents.
Results: The results indicated that male influencers impact male consumers more than female consumers, while female influencers impact female consumers more than male consumers. Age of consumer does not affect the gender-based impact results. In addition, the results indicate that only few influencers have more impact on specific product type, thus, influencer’s impact based on product type is not so common.
Recommendations: It is recommended for the companies to find influencers who are having a lot of impact on a specific product type that matches the product they want to promote, and to select the influencer based on the customers they are targeting, if companies are targeting female customers, they should look for popular female influencer, and if they are targeting male customers, they should look for popular male influencer.

Nasal Preinitials in Tangut Phonology
Authors: Gong Xun 
Published: January 2022

Gong Hwang-cherng proposed that the Tangut language has a distinction between short and long vowels. To date, however, no reliable correlates have been found regarding the actual phonological nature of the distinction. A careful examination of Chinese loanwords in Tangut and Sino-Tangut pronunciation reveals that the “vowel length” distinction should be revised to that of the presence vs. absence of a nasal preinitial. The pair “weed” vs. “tomb,” borrowed respectively from Chinese 蒲 bu and 墓 muH (the latter from a Northwest-type reflex with *mb-), hitherto reconstructed as buʶÅ {buÅ} vs. buʶ¹ {bu¹}, should be revised to buʶ¹ vs. mbuʶ². The reconstructed nasal preinitial not only has a close typological parallel in Modern West Rgyalrongic, but is equally reflected in other sources of evidence, most strikingly Sanskrit transcription and fǎnqiè. The revision solves a large number of problems in the historical phonology of Tangut, though not without raising some new ones, especially in connection with the treatment of Proto-Rgyalrongic preinitials before nasals.

A Novice Teacher Researcher’s Action Research Project: Posing Problems to Promote Concepts of Graphs in Calculus
Authors: Ovadiya Tikva 
Published: January 2022

A novice mathematics teacher researcher (TR) conducted an “interactive action research” (AR) to determine what problems would be most beneficial to teach her students about creating graphs based on a function’s attributes. After a number of trials that included adjusting her goals, the TR successfully designed problems appropriate for her goals. This paper describes the problem-posing process the TR used to derive the problems, and which include the four steps described in the literature: i) plan the problem, ii) pose it, iii) solve it, and iv) organize and complete it (see Güveli, 2015) plus an additional overall step added by this author, v) develop awareness of common perceptions (and misconceptions) that students have with respect to graphing. The contribution of this study is twofold. The first is the theoretical model of a five-step AR process, which can be used to guide TRs when conducting a mathematics posing problem AR: mathematical objective, source of inspiration, concerns related to formulation, mathematical uncertainties, and decisions taken. The second is that it demonstrates how TR’s formative assessment of the student’s solutions can improve her problem-posing heuristics and guide her to adjust her didactic goal(s). In addition, this paper documents her professional development on two aspects: developments and transitions in her thinking, and her development in skills required for reaching a didactic or mathematical goal. As part of a participatory action-research project, students at the vocational upper-secondary Natural Resource Use programme in Sweden were introduced to infrared cameras in their courses. Students were video recorded as they used infrared cameras in the investigation of pigs’ physiology and health in the school’s pig house and explained generated infrared images in whole-class dialogue, together with involved teachers and researcher. Students found that a pig’s injured leg has high temperature, but also, more surprisingly, udder abcesses with lower temperature than the surrounding healthy udder tissue. Students and teachers expressed excitement in explaining the results. From the perspective of seeing vocational education as a kind of cognitive apprenticeship, students’ investigations and dialogue with the teachers and researcher are characterised as an example of authentic activity in a community of learners, where expertise was distributed across all participants.
PERANCANGAN AR DAN VR BERBASIS ANDROID UNTUK MEDIA PROMOSI PENGEMBANG PERUMAHAN PT. GRIYA PANTURA MANDIRI KENDAL

Published: January 2022

Augmented Reality (AR) and Virtual Reality (VR) which are one of the top ten strategic technology trends for 2019 and continue to be developed massively in this 2020, have been widely applied in various mobile applications by many companies in this industrial revolution era 4.0. AR can be applied to help the promotion for housing developers where users can see the 3-dimensional shape of the types of houses offered, while VR allows users to explore each part of the house in a virtual 3D. Pre-existing brochures are used as markers for this application to work, so that AR and VR applications can be a complement to promotional media. The design method used in this paper is Research and Development (RnD). Salespeople can offer types of houses to prospective customers without having to print multiple brochures, but with just one brochure and one android smartphone to present, so the promotion costs are more efficient.

There are many archives owned by AMNI Maritime University in Semarang. The archiving system carried out at the AMNI Maritime University Semarang is still not well organized and neat because it is only based on archive classification, so if you have to look for archives such as archive numbers or archive dates, you will experience problems because you have to find the files needed one by one in the filing cabinet. The sequential search algorithm can be applied to the search for employee document numbers at the Maritime University AMNI Semarang and works well as planned. The employee document archive information system at the Maritime University AMNI Semarang can be used to manage the employee document archive more optimally, controlled, well organized and maintained so that the archive is not easily damaged
