Published: December 2021

Buttabean Motivation (BBM) is a grassroot initiative aiming to improve Pasifika and M?ori health through free community bootcamps offering exercise, motivation and nutritional advices, and with online programmes of workouts and meal plans. It is a dynamic organisation, responding to community needs,  providing practical solutions to issues such as food insecurity and influenza vaccination while maintaining its core focus of reducing obesity among Pasifika and M?ori through nutrition and physical activity.. BBM forms active and changing relationships with numerous organisations that offer support. They would like to work with the government and the district health boards, but the structure and changing nature of their organisation does not fit traditional funding models. To show that BBM is effective for Pacific people beyond anecdotal evidence, BBM has partnered with University of Auckland researchers. The research team are using a kaupapa M?ori and co-design approach to explore how BBM might benefit the community and reduce health inequities, especially whether BBM’s model of social collectivism enables sustainable weight loss for Pasifika and M?ori in the current obesogenic environment. Weight reduction programmes typically find that after initial success, participants have reverted to pre-programme weight by five years. BBM’s “whole of life change” approach may lead to sustained weight loss not demonstrated by other programmes. Using co-design, a BBM/University of Auckland partnership is evaluating the effectiveness of the BBM programme for sustained health and wellbeing. BBM is grounded in the Pacific/indigenous health frameworks fonofale, te whare tapa wh? and fa’afaletui addressing physical, mental, spiritual, family and social health in the context of people’s lives. The research will use a longitudinal cohort approach study design, using metrics and outcomes of relevance to its participants and the programme. A systems analysis will facilitate understanding of the strengths and challenges to delivering a holistic and sustained service for the community. BBM provides much promise in reducing health inequities for Pasifika and M?ori, however the model creates challenges for ongoing funding, business structure and evaluation. The goal is to find ways that both the programme and social institutions, including funders and evaluators, can adapt to meet these real-world challenges.
Exploring Key Components of Successful Distance Learning Programs: A Case Study in Palau
Authors: Thorne Tyler , Smith Maiya , Dever Gregory
Published: December 2021

Introduction: The Pacific faces multiple healthcare crises, including high rates of noncommunicable diseases, infectious disease outbreaks, and susceptibility to natural disasters. These issues are expected to worsen in the coming decades, increasing the burden on an already understaffed healthcare system. Improvements in technology and accessibility have increased telehealth’s utility and have already proven to reduce costs and increase access to care in remote areas. Telehealth includes distance learning; a form of education that can help alleviate many healthcare issues by providing education to healthcare professionals and upskilling staff, which can promote workforce retention and decrease patient mortality. Distance learning programs at the Ministry of Health in the Pacific nation of Palau were examined and key elements to their success were identified.

Methods: Thirty-four people, mostly health professionals at the Belau National Hospital in Palau were interviewed. Standardized questions and surveys were conducted in person throughout the month of July 2019.

Findings: Two examples of successful distance learning programs were identified. Consulting with staff and analyzing each program, four factors for a successful distance learning program were identified: having a cohort, having a facilitator, dedicated study time off from work, and motivation.

Conclusions: In countries as geographically isolated as the Pacific, with poor access to specialists and resources, telehealth has the potential to radically change how healthcare is delivered. Palau shares similar resources and issues as other countries in the Pacific and the lessons learned from their successful programs can be adapted to help other Pacific nations develop their own distance learning programs.
Fefine Tonga moe ifi tapaka: A qualitative study to explore Tongan female tobacco smoking & cessation in the Auckland region.
Authors: Palavi Linda , Nosa Vili
Published: December 2021

ABSTRACT

Introduction

Tongan female smokers’ smoking experiences have manifested within a realm of socioeconomic and cultural conditions in New Zealand with cessation service engagement relatively low. Due to the projected tobacco burden attributed to Pacific women, pertinent research proves vital to bettering understandings of smoking and cessation within this group. This study explored the knowledge and experiences of smoking and smoking cessation services among Tongan women aged 16 years and over, living in the Auckland region.

Methods

This qualitative research design utilised the Kakala model to ensure processes were culturally appropriate and meaningful. Data was collected through eight face-to-face semi-structured interviews transcribed by the researcher and employed the toli, teu and luva process from the Kakala model to form relevant themes.

Findings

The findings suggest smoking among Tongan females is a social vector that marks independence and maintains friendships, despite known adverse health effects and stigma. It is characterised as stress relief that has habituated into day-to-day routine for most. Their aspirations to live longer for their family is a strong motivator but quitting remains difficult and should be done autonomously by the individual.

Tongan female smokers stated smoking cessation services as ineffective and need to be adapted and consulted by and within the community. Stop smoking services should encourage autonomy among Tonga women in order to improve utilisation and engagement. Service delivery for Tongan female smokers needs to be on-going and long-term support reoriented within the community for more Tongan women to become completely smokefree.

Conclusions

Tongan female smoking in New Zealand is comprised of experiences surrounding friendships, family and culture. This study concludes that although smoking harms are widely known, cessation service delivery can be transformed by utilizing existing Tongan cultural roles such as that of the mehikitanga (paternal aunt) to encourage non-smoking among extended female generations.
Performance Evaluation of MC-CDMA Systems with Single User Detection Technique using Kernel and Linear Adaptive Method
Authors: Fateh Rachid , Darif Anouar , Safi Said
Published: December 2021

Among all the techniques combining multi-carrier modulation and spread spectrum, the multi-carrier code division multiple access (MC-CDMA) system is by far the most widely studied. In this paper, we present the performance of the MC-CDMA system associated with key single-user detection techniques. We are interested in problems related to identification and equalization of mobile radio channels, using the kernel method in Hilbert space with a reproducing kernel, and a linear adaptive algorithm, for MC-CDMA systems. In this context, we tested the efficiency of these algorithms, considering practical frequency selective fading channels, called broadband radio access network (BRAN), standardized for MC-CDMA systems. As far as the equalization problem encountered after channel identification is concerned, we use the orthogonality restoration combination (ORC) and the minimum mean square error (MMSE) equalizer techniques to correct the distortion of the channel. Simulation results demonstrate that the kernel algorithm is efficient for practical channels.

Published: December 2021

Natural based functional food and beverages have gained market interest in the last
decade. Functional beverages, especially those enriched with nutrients and bioactive
compounds, are of particular interest. Maintaining the nutritional or bioactive activity of
these components along with their sensory attributes in the final product remains to be a
challenge. Health benefits from bioactive substances, like fucoxanthin and phlorotannins,
in marine algae makes it a promising commodity of an archipelago country. However,
nutritional components, their stability, and an understanding of their nutritional and
bioactive component availability require further investigation. Here we prospected natural
and sustainable antioxidant additives from brown algae, Sargassum polycystum C Agardh,
to enrich a cold dairy-based beverage. Food-grade extraction of S. polycystum was done
by using 96% Ethanol to macerate dried powder algal. Identification of fucoxanthin in the
extract was performed using High-Performance Liquid Chromatography (HPLC)
(Prominance Shimadzu). We employed the 2,2-diphenyl-1-picrylhydrazyl method to
quantify the antioxidant activity of extract alone and extract in three beverage
formulations containing 0.02, 0.05, and 0.1 mg/cup S. polycystum extract. Sensory
evaluation and viscosity analysis comparing our product to the commercially available
product was also performed. Results showed that the combination of S. polycystum extract
with sunflower oil was able to maintain antioxidant activity when stored at 4°C.
Formulation 2 of dairy-based beverages passed the sensory evaluation. This study was the
first to report the application of S. polycystum extract on a cold dairy-based beverage. This
product was developed considering the low stability of the bioactive compound,
fucoxanthin. More comprehensive sensory evaluation and optimization for large scale
production are highly required.

Freeze-drying is a very gentle dehydration method to preserve the highest quality and give
the final product a longer shelf-life, based on the principle of removing the ice
by sublimation. This research aimed to study freeze-dried manufacturing processes of
vegetable carving for application in the foodservice industry. Plant materials used in this
study were pumpkin, carrot and Chinese radish which were carved into a rose shape. To
prepare, all carved-rose vegetables were dipped in 1.0% CaCl2 solution as a firming agent
for 5 mins before freeze-dried operations at the temperature of –50°C under vacuum (~30
Pa) for 50 hrs. Dyeing operation was conducted specifically in carved-rose Chinese radish
using pink (0.05 and 0.1%) and red (0.05 and 0.1%) food-grade colour after pretreatment
with CaCl2 . The results showed that dried carved-rose vegetables had low water activity
(0.32-0.42) and moisture content (8.01-11.44%). The physical properties of freeze-dried
pumpkin and carrot carving were firmed and presented a spongy texture with small
bubbles spread continuously throughout the piece which helps protect the structural
collapse. However, carved-rose radish had a slight shrinkage but it was restored as fresh
after immersing in water. Rehydration time was 5 mins for pumpkin and carrot, and 10
mins for Chinese radish which showed remarkable that firm-liked fresh vegetables. Then,
freeze-dried vegetables were packed in an aluminum bag filled with nitrogen gas and kept
at 25±1°C for 2-months storage. The sensory characteristics evaluated by specialists were
ranged in the medium to very like throughout the storage periods. Thus, freeze-dried
carved-rose vegetable seems to be very interesting, moreover, conduction on a larger scale
for the foodservice industry was particularly noticeable.

Published: December 2021

In this study focused on to describing the types and functions of the Tionghoa community utterances that tend to use Hokkien language and the non Tionghoa community that typically to use Indonesian language. The theory proposed by Austin and Leech was used to classify and analyze the speech act data delivered and collected through a non-participative observation and taking notes technique. The data were obtained from five traditional markets in Medan from July to September 2020. The data showed five kinds of speech acts from both the Tionghoa and non-Tionghoa communities. A directive speech act was the dominant speech act obtained because the directive speech act influenced the interlocutor. In this case, the customer dominated the seller to do what the customer demanded. The directive speech act also showed the chief ordering function found in the Tionghoa community, and the bargaining function was located in the nonTionghoa community. The ordering directive speech act prevalent in Tionghoa speakers related to the character of the majority of Tionghoa community members in Medan, which was straightforward. In this case, they gave orders or directly asked for what they needed or sought. Meanwhile, in the non-Tionghoa community, the utterances refer to buying and selling laws, dominated by bargaining utterances, both bargaining for goods or prices. In comparison, the declarative speech act is the minor speech act found to express resignation towards the COVID-19 condition.

Peramalan bisa digunakan dibidang manapun yang mana membutuhkan sebuah prediksi akan keberadaan data di masa yang mendatang. Forecasting bisa diterapkan salah satunya untuk membantu anggaran penjulan ke periode berikutnya. Data time series diperoleh dari data penjualan selama periode tertentu penjualan suatu produk bisa digunakan sebagai dasar forecasting-nya. Restock barang yang berlebih tidak baik untuk sebuah toko, karena ada kemungkinan barang yang dibeli tidak laku kedepannya. Perlu adanya proses kontrol yang baik untuk restock barang, salah satunya yang bisa digunakan adalah menggunakan prediksi restock barang dagangan menggunakan single exponential smoothing (SES). Data penjulan yang digunakan ada dua macam yaitu Beras Koi 5kg-an dan Minyak Bimoli 900ml-an. Dari hasil perhitungan SES diperoleh nilai alpha yang bagus untuk peramalan Beras Koi 5kg-an adalah 0,46. Sedangkan nilai alpha untuk Minyak Bimoli 900ml-an adalah 0,704. Nilai alpha tersebut diperoleh dari perhitungan nilai MSE yang terkecil. Hasil prediksinya menunjukkan pada periode berikutnya (15-30 September 2021) menunjukkan adanya penurunan jumlah penjualan barang dari kedua produk tersbut, sehingga pemilik toko bisa mengurangi jatah belanjanya.
On Curiosity
Authors: Cochoy Frank
Published: January 2022

What draws us towards a shop window display? What drives us to grab a special offer, to enter the privileged circle of premium newspaper subscribers, to peruse the pages of an enticing magazine? Without doubt, it is curiosity - that essential force of everyday action which invites us to break from our habits and to become transported beyond our very selves. Curiosity (whether healthy or unhealthy) is one of the favourite tricks of market seduction. Capturing a public - attracting the attention of a reader, seducing a customer, meeting the expectations of a user, persuading a voter ... - often requires the construction of a set of technical devices that can play upon people's inner motivations. Cochoy invites us to take a sociological trip into these cabinets of curiosity, accompanied throughout by Bluebeard, a fairy tale that is both a model of the genre and a pure curiosity machine. At once a work of history and economic anthropology, the book meticulously analyses the devices designed by markets to arouse, excite, and sustain curiosity: a window display, practices of 'teasing', packaging, bus shelters, mobile internet technologies, to name but a few. In the Bettencourt and Strauss-Kahn affairs and the Wikileaks controversy, Cochoy also uncovers the work of investigative journalism and its attention-grabbing 'scoops', revealing the secrets of the revealers of secrets. Available in English for the first time, this major work will arouse readers' curiosity over the course of its unusual and colourful journey. By the end, now better informed and more cautious, they will be able to identify the traps of which they are the target. So long as curiosity is kept at bay, at least!
The EFFECT OF HYDROPHYTES ON THE PERFORMANCE OF SECONDARY CANAL
Authors: Khan Haroon
Published: December 2021

The hydrophytes in canal effect directly canal performance by reducing water velocity, enhances sedimentation and reduce canal cross section area which raise water level and reduces water flow. Indirectly the hydrophytes detaches from their origin and flow with water stuck with outlet and reduces its proportionality. In this regard a study was conducted on secondary canal known as Yar Husain Minor (YHM) of Maira Branch Canal, which is part of the Upper Swat Canal Irrigation System in Khyber Pakhtunkhwa, Pakistan. Maira Branch Canal and its secondary canal were designed for Crop Based Irrigation Operation (CBIO), which could supply irrigation water for maximum copping intensity (180%) even during peak periods of irrigation requirements. The current water allowance was 0.67 Ls-1 ha-1 (6.6 mm day-1), which was based on the maximum crop water requirements. The several challenges for operation of YHM and other secondary canals of Maira Branch came from physical barrier mostly in the form of hydrophytes on the performance of YHM canal. Further challenges came from the fact that it receives water from River Swat which is turbid in summer and River Indus (Tarbela Reservoir) which is clear with low turbidity. This caused sedimentation and growth of hydrophytes in the YHM. Furthermore Triangular Profile Crump’s weirs were in all secondary canals including YHM for proportional division to the tertiary outlets (moghas). The study objectives were to investigate the effects of hydrophytes on canal capacity and at the outlets on the performance of the YHM. Hydrophytes growth was observed in head reaches of canal and samples were collected and were identified at the Department of Weed Science & Botany, The University of Agriculture Peshawar. Five types of aquatic weeds were identified. The hydrophytes growth in canal head reaches directly reduces the cross section by more than 50%. Indirectly the detached hydrophytes were get stuck in the outlets and affected its performance. Therefore, daily discharges were measured with/without detached hydrophytes at each outlet from staff gauging. Frequency was based on days stone hydrophytes present divided by total time. It was concluded that secondary canal performance was low due to hydrophytes. The hydrophytes and users interventions influenced the outlets performance by 80%. Trifurcators type outlets were more prone to influence by hydrophytes followed by bifurcators outlet.

Weed infestation is a major problem and matter of concern as it reduces yield as well as quality of many crops including sugar beet. Manual weeding is very tedious, costly, time consuming and most probably non-availability of trained and skillful labor is another issue. Keeping in view these facts, an experiment was performed to evaluate the efficacy of dual gold on the weed biomass (gm-2) and on the growth and yield components of sugar beet (Beta vulgaris L.) cv. California-KWS during 2013-14 and 2014-15. The study was performed using RCBD having five treatments and three replications. The treatments included different application times (pre-emergence application and application after 15, 30 and 45 days after emergence) of dual gold (s-Metolachlor) and a control (weedy check). Data were recorded on fresh and dry weed biomasses (g m-2), number of leaves plant-1, leaf area plant-1 (cm2), leaf and root weights plant-1 (g), sucrose%, TSS%, root and sugar yields (t ha-1). The results showed significant variation among the treatments for all parameters during both years of study. Among the treatments the dual gold (s-Metolachlor) applied as pre-emergence reduced weed fresh and dry biomasses (g m-2) and also enhanced number of leaves plant-1, leaf area (cm2), leaf and root weight plant-1, sucrose%, TSS%, root and sugar yields (t ha-1) during both years. Hence it is concluded that dual gold (s-Metolachlor) applied as pre-emergence is best for eradicating weeds at early stages of growth and hence improving yield and quality of sugar beet under Dera Ismail Khan Conditions.

Fiber-reinforced polymer reinforcement or polyurea reinforcement techniques are applied to strengthen unreinforced masonry walls (UMWs). The purpose of this experimental study is to verify the out-of-plane reinforcing effect of sprayed glass fiber-reinforced polyurea (GFRPU), which is a composite elastomer made of polyurea and milled glass fibers on UMW. The out-of-plane strengths and ductile behaviors based on various coating shapes are compared in this study. An empirical formula to describe the degree of reinforcement on the out-of-plane strength of the UMW is derived based on the experimental results. It is observed that the peak load-carrying capacity, ductility, and energy absorption capacity gradually improve with an increase in the strengthening degree or area. Compared with the existing masonry wall reinforcement method, the GFRPU technique is a construction method that can help improve the safety performance along with ease of construction and economic efficiency. Doi: 10.28991/CEJ-2022-08-01-011 Full Text: PDF
