Determinant Factors for Managing Innovation in the Malaysian Public Sector
Authors: Ab Rahman Zety Norhaiza , Ismail Norain
Published: February 2018

Since 1991, the government has started the forces to encourage public sector to innovate in order to strengthen the capability and solve problems at workplace for the benefit of organization and its people. The focuses of this forces is to create value creation, encourage cost reduction, and provide services that meet aspirations and people's expectations through high impact ideas. However, to achieve these focuses, public sector faces few challenges that affect the management of innovation; which includes lack of leadership skills and poor innovative culture to stimulate innovation. Although there are various initiatives conducted to enhance the management innovation, the innovative performance is still less satisfactory. Therefore, this paper aims to discuss the determinant factors that affect managing innovation in the selected public sectors which consist of two categories; patron and executor agencies. Thematic approach was used to analyse the interview data. Findings from the interview suggested that in the organization, an employee especially a leader should show his full commitment towards innovative culture, he needs to be committed and supportive and communicate well with the employees and he also should provide attractive rewards to encourage the innovative culture for an effective management innovation. These determinant factors need to be considered as high significant for the public sector to develop new strategies or approaches in managing innovation towards sustaining their competitive advantages in a long term for the benefit of public.

Authors: Shaari Mohd Shahidan , Abdullah Diana Nabila Chau , Razali Razleena , Al-Hakim Md Saleh Mohamad Luqman
Published: February 2018

The Phillips curve shows the trade-off relationship between the inflation and unemployment rates. A rise in inflation due to the high economic growth, more jobs are available and therefore unemployment will fall. However, the existence of the Phillips curve in high-income countries has not been much discussed. Countries with high income should have low unemployment rate, suggesting a high inflation. However, some high-income countries, the United States in 1970s for example, could not avert stagflation whereby high unemployment rate and inflation occurred in the same time. This situation is contrary to the Phillips curve. Therefore, this study aims to investigate the existence of the Phillips curve in high-income countries for the period 1990-2014 using the panel data analysis. The most interesting finding of this study is the existence of a bidirectional relationship between unemployment rate and inflation rate in both long and short runs. Therefore, the governments should choose to stabilize inflation rate or reduce unemployment rate

Postpartum care is highly important to prevent maternal and infant morbidity. In Malaysia, there are several traditional postpartum care practices by mothers. Different states adopted different ways to perform those practices. In spite of long and established practices in Malaysia, its effect and safety profile is not well understood. This study aims to gain an understanding of the traditional practices that Malay women follow in relation to postpartum care and the rationales underpinning such practices. A cross sectional study (n=100) was conducted using self-administered questionnaire consists of demographic information, practice of postpartum care and knowledge of postpartum care. Data was analyzed using Statistical Package Social Software (2.0). The findings shown that, there was no significant association of socio-demographic data with confinement period (p>0.05). For postpartum dietary practice, there were only association between age and encourage more water intake (p=0.047, p<0.05) and also between number of children and prohibit greasy food (p=0.032, p<0.05). For association between socio-demographic data and postpartum physical practice, there was only association between age and body scrub (p=0.046, p<0.05). The most significant factor that influenced postpartum care practice and its knowledge was family tradition with 83% and 97%, respectively. Traditional postpartum care practice is still significant and dominant among mothers in Kuantan, Pahang. This information is important for health care professional to educate women and provide strategies to help them to integrate their beliefs and the practices recommended in contemporary health care practice.

Published: February 2018

The participation of students in the process of learning is one of the keys to ensure effective learning outcomes either in terms of knowledge or skill. However, teacher-centred teaching methods which have been practiced in this country after so long avert students to fully engage in the learning process especially in a classroom. Various attempts have been made by the government to emphasize student’s development in term of communication, creativity and innovation through the of process learning in class. It requires school to implement student-centred teaching methods such as cooperative learning. Cooperative learning is a teaching method that requires teachers not only interacts with the students but also with other teaching aids such as audio, video and computer. Therefore, this study was conducted to identify teachers' perception on the implementation of cooperative learning in the teaching and learning process in class. 25 teachers were selected as respondents. Mixed methods were used in this study, where the instrument of questionnaires and interviews were used to collect the data. Quantitative data analysis was made using descriptive statistics of frequency, mean and percentage. While, qualitative data analysis was based on the recommendations of the Miles & Huberman (1994). The findings showed teachers have a positive attitude toward cooperative learning and they are ready and feel confident to practice it. However, the constraints are classroom control, time and limited teaching aids

Published: February 2018

There is lack of studies on the use of metadiscourse markers; especially amongst international students studying in Malaysia and Malaysia are receiving scores of international students particularly from the Middle East annually. This study involves a textual analysis of students’ academic writing where the metadiscourse markers in 50 Arab IIUM students’ academic texts were identified and analyzed. The findings of this study indicated that Arab writers had a greater inclination for the deployment of the interactive markers (Total counts = 919) than interactional ones (Total counts = 592) as there was a higher percentage of interactive metadiscourse (60.8%) usage than the interactional ones (39.2%). It might be useful for English language teachers to integrate cultural considerations within their syllabus with regard to metadiscourse markers in order to prepare relevant materials based on their students’ needs as well as to develop the students’ awareness of the importance of these linguistic features.

This paper deals with the question: To what extent do religiosity characteristics, contribute to the influence of volunteering intention among Malaysian Muslim students during disasters? To answer this research question, we focused the students in public universities. The finding concerns found that religiosity increases the likelihood of volunteering intention, implying that religious affiliation of youth increases the likelihood of volunteering. This is in line with previous research, that religious attendance is related positively to volunteering. These results confirm the idea that support of the religious attributes community plays quite a large role in volunteering process. However, it a bear that volunteering is not only dependent on religious community, but also on individual motivation.

Published: February 2018

The deployment of Internet Protocol version 6 (IPv6) has raised security concerns among the network administrators. Thus, in strengthening the network security, administrator requires an appropriate method to assess the possible risks that occur in their networks. Aware of the needs to calculate risk in IPv6 network, it is essential to an organization to have an equation that is flexible and consider the requirements of the network. However, the existing risk assessment equations do not consider the requirement of the network. Therefore, this paper presents the adaptation of grounded theory to search for elements that are needed to develop IPv6 risk assessment (IRA6) equation. The attack scenarios’ experiments; UDP Flooding, TCP Flooding and Multicast attacks were carried out in different network environment to show how the IPv6 risk assessment equation being used. The result shows that the IRA6 equation is more flexible to be used regardless the network sizes and easier to calculate the risk value compared to the existing risk assessment equations. Hence, network administrators can have a proper decision making and strategic planning for a robust network security.

Published: February 2018

Mangifera indica var Harumanis is one of the exotic mango cultivated in Perlis, Malaysia. It economic importance increased in recent years due to the popularity attributed to it excellent taste, sweet and aromatic fragrance. Supply of Harumanis cannot meet market demand, mainly due to the difficulty of raising the crops and the short and uncertain harvesting seasons. The cultivation of Harumanis in greenhouse was found to be feasible to mitigate the short coming. However, the cultural practices of high density planting in greenhouse calls for regular pruning to meet the desired canopy. Regular strategic pruning produced pruning waste with potential economic value. This research was done to quantify the by-products produced by pruning from three 1/2 acre greenhouses, under the ecological and climatic of Perlis. The fresh biomass of waste collected during primary, secondary and tertiary pruning were determined. The pruning waste produced was 0.676kg per plant equivalent to 146.4kg per greenhouse during primary and secondary pruning. Estimation of fresh biomass waste produced during floral induction determine by regression was 816 kg per greenhouse with the expected total of 40.8 ton from 50 greenhouses. In view of the fact that the mango plant management practice was from the clean agricultural, the waste can be potentially utilized for green manufacturing. This was the first attempted to quantify pruning waste in mango cultivation before further utilization of pruning waste.

Melanomas of the female genital tract may occur in the vulva, the vagina, the ovary or the cervix. Pregnancy has been considered an aggravating factor in the evolution and prognosis of melanoma. A 35-year-old female presented with vaginal bleeding 2 months after a term cesarean delivery. An endovaginal ultrasound revealed a lesion in the uterine cervix. The pathological report revealed a small round-cell neoplasm, and the immunohistochemistry confirmed the diagnosis of malignant melanoma. A positron emission tomography revealed an expansive hypermetabolic lesion centered on the cervix, and hypermetabolic lesions in the liver and right kidney. Non-surgical treatment was provided, with biochemotherapy followed by ipilimumab and nivolumab. The patient died one year later. Postpartum vaginal bleeding, even if late-onset, should be investigated, as it may be a pregnancy-associated malignant melanoma, which has a poor prognosis.

Published: February 2018

Total knee arthroplasty continues to increase in popularity and remains the most common joint replacement surgery. The success of total knee replacement surgery is attributed to improved outcomes, a better patient experience, and lower cost. Rapid recovery total knee replacement protocols have led to these advances by decreasing length of hospital stay, minimizing readmissions, and reducing the cost of surgery. Rapid recovery total knee replacement pathway efforts should focus on preoperative education, optimization of modifiable risk factors, and identification of patients that may not be suitable for this pathway.

Published: February 2018

Post-match assessment of creatine kinase (CK) activity and delayed-onset muscle soreness (DOMS) are common markers of exercise-induced muscle damage and recovery status in soccer players. These responses have not been examined in youth female players. This study examined the effect of competitive match play on CK activity and DOMS in elite youth players. Thirty-four elite female players, divided into three chronological age groups (U13, n=11; U15, n=10; U17 n=12). Players completed baseline testing for CK and DOMS that was repeated immediately (for DOMS), 80, 128 and 168 h post-competitive match play for CK. Significant time effects were reported for CK (P=0.006) and DOMS (P<0.01). Significant differences between baseline and 168 h post-match were reported for CK (P<0.01), with significant group differences between the U13 and U17 groups for CK (P<0.01). All parameters returned to baseline in U17s at 168 h, but increased CK was evident for U13s and U15s at 168 h. In conclusion, seven days may be insufficient for biochemical recovery in youth female athletes. Therefore, monitoring strategies to assess muscle damage between training and match play should be considered to track recovery and potentially reduce muscular injury risk.
Terahertz radiation generation by beating of two laser beams in a collisional plasma with oblique magnetic field
Authors: Hematizadeh Ayoob , Jazayeri Seyed Masud , Ghafary Bijan
Published: February 2018

A scheme for excitation of terahertz (THz) radiation is presented by photo mixing of two super-Gaussian laser beams in a rippled density collisional magnetized plasma. Lasers having different frequencies and wave numbers but the same electric fields create a ponderomotive force on the electrons of plasma in the beating frequency. Super-Gaussian laser beam has the exclusive features such as steep gradient in laser intensity distribution, wider cross-section in comparison with Gaussian profiles, which make stronger ponderomotive force and higher THz radiation. The magnetic field is considered oblique to laser beams propagation direction; in this case, depending on the phase matching conditions different mode waves can propagate in plasma. It is found that amplitude and efficiency of the emitted THz radiation not only are sensitive to the beating frequency, collision frequency, and magnetic field strength but to the angle between laser beams and static magnetic field. The efficiency of THz radiation can be optimized in a certain angle.

Published: February 2018

Functional materials represented by ferromagnetics and ferroelectrics are widely used in advanced sensor and precision actuation due to their special characterization under coupling interactions of complex loads and external physical fields. However, the conventional devices for material characterization can only provide a limited type of loads and physical fields and cannot simulate the actual service conditions of materials. A multi-field coupling instrument for characterization has been designed and implemented to overcome this barrier and measure the comprehensive physical properties under complex service conditions. The testing forms include tension, compression, bending, torsion, and fatigue in mechanical loads, as well as different external physical fields, including electric, magnetic, and thermal fields. In order to offer a variety of information to reveal mechanical damage or deformation forms, a series of measurement methods at the microscale are integrated with the instrument including an indentation unit and in situ microimaging module. Finally, several coupling experiments which cover all the loading and measurement functions of the instrument have been implemented. The results illustrate the functions and characteristics of the instrument and then reveal the variety in mechanical and electromagnetic properties of the piezoelectric transducer ceramic, TbDyFe alloy, and carbon fiber reinforced polymer under coupling conditions.
Coexistence of multiple multimode nonlinear mixing regimes in a microelectromechanical device
Authors: Ganesan Adarsh , Seshia Ashwin
Published: February 2018

This paper builds on the recent demonstrations of two-mode three-wave mixing and three-mode four-wave mixing pathways. In these individual mixing mechanisms, the drive and resonant frequencies intrinsically couple to generate frequency combs with spacing defined by the separation between drive and resonant frequencies. Such frequency combs resulting from N-mode N+1-wave mixing processes possess spectral characteristics which are strikingly different from those of nominal N-mode parametric resonances. Now, in this paper, we experimentally show the possibility to simultaneously trigger one N=N1-mode N=N1+1-wave mixing and one nominal N=N2-mode parametric resonance through the significant drive of a single phonon mode. This specific demonstration, when set alongside previous studies, represents an important step towards understanding phononic frequency comb processes.
Coexistence of unipolar and bipolar resistive switching behaviors in NiFe2O4 thin film devices by doping Ag nanoparticles
Authors: Hao Aize , Ismail Muhammad , He Shuai , Huang Wenhua , Qin Ni , Bao Dinghua
Published: February 2018

The coexistence of unipolar and bipolar resistive switching (RS) behaviors of Ag-nanoparticles (Ag-NPs) doped NiFe2O4 (NFO) based memory devices was investigated. The switching voltages of required operations in the unipolar mode were smaller than those in the bipolar mode, while ON/OFF resistance levels of both modes were identical. Ag-NPs doped NFO based devices could switch between the unipolar and bipolar modes just by preferring the polarity of RESET voltage. Besides, the necessity of identical compliance current during the SET process of unipolar and bipolar modes provided an additional advantage of simplicity in device operation. Performance characteristics and cycle-to-cycle uniformity (>103 cycles) in unipolar operation were considerably better than those in bipolar mode (>102 cycles) at 25 °C. Moreover, good endurance (>600 cycles) at 200 °C was observed in unipolar mode and excellent nondestructive retention characteristics were obtained on memory cells at 125 °C and 200 °C. On the basis of temperature dependence of resistance at low resistance state, it was believed that physical origin of the RS mechanism involved the formation/rupture of the conducting paths consisting of oxygen vacancies and Ag atoms, considering Joule heating and electrochemical redox reaction effects for the unipolar and bipolar resistive switching behaviors. Our results demonstrate that 0.5% Ag-NPs doped nickel ferrites are promising resistive switching materials for resistive access memory applications.
Ultrafast spectral dynamics of dual-color-soliton intracavity collision in a mode-locked fiber laser
Authors: Wei Yuan , Li Bowen , Wei Xiaoming , Yu Ying , Wong Kenneth K. Y.
Published: February 2018

The single-shot spectral dynamics of dual-color-soliton collisions inside a mode-locked laser is experimentally and numerically investigated. By using the all-optically dispersive Fourier transform, we spectrally unveil the collision-induced soliton self-reshaping process, which features dynamic spectral fringes over the soliton main lobe, and the rebuilding of Kelly sidebands with wavelength drifting. Meanwhile, the numerical simulations validate the experimental observation and provide additional insights into the physical mechanism of the collision-induced spectral dynamics from the temporal domain perspective. It is verified that the dynamic interference between the soliton and the dispersive waves is responsible for the observed collision-induced spectral evolution. These dynamic phenomena not only demonstrate the role of dispersive waves in the sophisticated soliton interaction inside the laser cavity, but also facilitate a deeper understanding of the soliton's inherent stability.

Published: February 2018

The use of hydropower has expanded in recent years in southwest China, playing a key role in the success of China's West-to-East energy strategy. Although installed hydropower capacity has reached a record high, the problem of abandoned water has intensified and has been gradually highlighted by researchers. Abandoned water has resulted in a significant waste of carbon-free and inexpensive renewable energy, which is not conducive to China's goals to reduce emissions to save energy. This waste has seriously affected the development of China's hydropower industry. Therefore, now is the time to analyze the main reasons for the abandoned water problem and to identify the crux of the problem. In this paper, we collected the actual operation data of all the power stations in the case area and established the mathematical model according to the quantity of abandoned water as well as the actual and the theoretical output curve of the power station to quantify the abandoned water into energy loss. We then classified the abandoned water according to three groups of causes, namely, generation-side, line-side, and market-side causes. In 2016, the total energy loss of abandoned water of Sichuan Province was 28.73 × 109 kW h, of which the generation-, line-, and market-side causes account for 7.76%, 11.68%, and 80.56% of the energy loss, respectively. Therefore, the market-side causes are the main cause for the abandoned water problem. Such market-side causes primarily include the imbalance between electricity supply and demand, the provincial barriers of the local government system and its mechanisms, and the hysteresis congestion of the transmission lines. Seizing the favorable opportunity presented by new power system reforms in China, this study proposes several market-oriented measures to improve hydropower consumption capacity.

The chapter addresses topics that contribute to well-being, such as the relationship between higher incomes and resident happiness, and the role of tourism development in enhancing social comparison as a force in defining resident happiness. Also presented is a case study focusing on tourism development in relation to residents' well-being in Aruba. The gaps in the literature are highlighted and future research stemming from the insights gained from the literature review as well as directions for policy-makers are discussed.
Destination management: a network perspective.
Authors: McLeod M. , Scott N.
Published: February 2018

This chapter explores, using a case study approach and network analysis, the coordination of tourism activities within a destination and thereby highlight the importance of destination management collaboration practices for tourism destination success. The case study is that of a small island tourist destination (the Grand Bahama Island in the Bahamas) that is in decline in terms of visitor numbers and expenditure. The results suggest a need to examine each stakeholder's role within the destination in order to improve destination management practices. Greater coordination is required to create sustained tourism performance, especially when a destination is recovering from a crisis.
The allied occupation of İstanbul and the construction of Turkish national identity in the early twentieth century
Authors: Şenışık Pınar
Published: February 2018

This article tells the story of the construction of Turkish national identity in the early republican era by addressing two canonical novels about occupied İstanbul:Sodom ve Gomore(“Sodom and Gomorrah”) by Yakup Kadri Karaosmanoğlu andBiz İnsanlar(“We People”) by Peyami Safa. Following the establishment of the Turkish Republic, Turkish nationalist intellectuals attempted to offer certain formulations and implemented various mechanisms to create a national self. The study aims to focus on the ways in which Karaosmanoğlu and Safa create the new Turkish national identity and deals with the questions of how occupied İstanbul was perceived by these intellectuals and how the memory of the Allied occupation of İstanbul, the collapse of the Ottoman Empire, and the National Liberation Struggle shaped Turkish elites' self-identification as well as their formulation of the national identity.
Dynamics of democratization and nationalization: The significance of women's suffrage and women's political participation in parliament in the Second Polish Republic
Authors: Leszczawski-Schwerk Angelique
Published: February 2018

This paper will examine processes of democratization and “nationalization” with specific reference to the Second Polish Republic (II Rzeczpospolita) and the interwar period. Starting from a consideration of broader theoretical concepts concerning transformation processes and their relation to the analytical categories of gender and ethnicity, it will discuss the introduction of political rights for women in 1918 as a case study for the role women's suffrage played in the process of democratization. A closer examination of the activity of three selected female members of parliament — a Polish, Jewish, and Ukrainian MP — in the Polish parliament will help to clarify if and how gender and ethnicity mattered in political institutions. It is argued that especially their speeches, by addressing specifically political demands in a certain way, that is, how they spoke in the name of their sex, nation, and ethnicity, show a close interlinkage between democratization and nationalization during the Second Polish Republic. From this will emerge a more general outlook on the extent to which the recognition of women's suffrage molded the basis for equality between women and men, and if the legally guaranteed equality really included all citizens of the Polish state.
Which is more effective for suppressing an infectious disease: imperfect vaccination or defense against contagion?
Authors: Kuga Kazuki , Tanimoto Jun
Published: February 2018

We consider two imperfect ways to protect against an infectious disease such as influenza, namely vaccination giving only partial immunity and a defense against contagion such as wearing a mask. We build up a new analytic framework considering those two cases instead of perfect vaccination, conventionally assumed as a premise, with the assumption of an infinite and well-mixed population. Our framework also considers three different strategy-updating rules based on evolutionary game theory: conventional pairwise comparison with one randomly selected agent, another concept of pairwise comparison referring to a social average, and direct alternative selection not depending on the usual copying concept. We successfully obtain a phase diagram in which vaccination coverage at equilibrium can be compared when assuming the model of either imperfect vaccination or a defense against contagion. The obtained phase diagram reveals that a defense against contagion is marginally inferior to an imperfect vaccination as long as the same coefficient value is used.

Highlights

– We build a new analytical framework for a vaccination game combined with the susceptible-infected-recovered (SIR) model.

– Our model can evaluate imperfect provisions such as vaccination giving only partial immunity and a defense against contagion.

– We obtain a phase diagram with which to compare the quantitative effects of partial vaccination and a defense against contagion.
A place-based alternative approach to food security: lessons learned from a neighborhood house
Authors: Yan Miu Chung , Sutherland Rory
Published: February 2018

The urban poor in many advanced economies have become subject to the problem of food security. So far, the charity food model, such as foodbanks and meal programs, has been the key solution to this problem. This model tends to undermine service users’ aspirations to eat healthy food and their agentic function for change. Using a case study approach, we examine how a place-based community organization, with roots in the settlement house tradition, adopts an alternative approach to food security issues in an impoverished neighborhood. Adopting an activist and a right-to-food philosophy, it has brought together local residents to collectively tackle prevalent hunger and unhealthy food supply problems in the community.

Plasma cells (PCs) acquiring long lifespans in the bone marrow (BM) play a pivotal role in the humoral arm of immunological memory. The PCs reside in a special BM niche and produce antibodies against past-encountered pathogens or vaccine components for a long time. In BM, cysteine-X-cysteine (CXC) chemokine receptor type 4 (CXCR4)-expressing PCs and myeloid cells such as dendritic cells are attracted to and held by CXC chemokine ligand 12 (CXCR12)-secreting stromal cells, where survival of the PCs is supported by soluble factors such as IL-6 and APRIL (a proliferation-inducing ligand) produced by neighboring myeloid cells. Although these stromal cells are also supposed to be involved in the support of the survival and antibody production, the full molecular mechanism has not been clarified yet. Here, we show that BM PDGFRα+Sca-1+-enriched mesenchymal stem cells (MSCs), which can contribute as stromal cells for hematopoietic stem cells, also support in vitro survival of and antibody production by BM PCs. IL-6 produced by MSCs was found to be involved in the support. Immunohistochemistry of BM sections suggested a co-localization of a minor population of PCs with PDGFRα+Sca-1+ MSCs in the BM. We also found that the sort-purified MSC preparation was composed of multiple cell groups with different gene expression profiles, as found on single-cell RNA sequencing, to which multiple roles in the in vitro PC support could be attributed.
Psychological morbidity in amyotrophic lateral sclerosis: Depression, anxiety, hopelessness
Authors: Lulé Dorothée , Ludolph Albert C. , Kübler Andrea
Published: February 2018

Amyotrophic lateral sclerosis is a devastating condition with progressive loss of movement, speech, and respiratory function, and no available cure. Following the development of clinical symptoms and after receiving a diagnosis, patients may develop psychological morbidity, such as depression, anxiety, and hopelessness. However, many patients adjust successfully in the course of the disease and maintain good psychological well-being, so that a decline in psychological well-being does not necessarily accompany loss of physical function. There are several major determinants of good psychological adjustment to chronic and terminal disease—intrinsic factors such as coping strategies and internal locus of control, and extrinsic factors such as high (perceived and actual) social support by families and multidisciplinary professional teams. Providing care with a holistic view of the patient is probably the most effective approach to supporting patients’ psychosocial adjustment to the disease and minimizing depression, anxiety, and hopelessness.
Young people and transitional care in rheumatology
Authors: McDonagh Janet E. , Gleeson Helena
Published: February 2018

Young people are distinctly different from children and adults and as such require developmentally appropriate, youth-friendly rheumatology services to meet their medical and psychosocial needs. Adolescent development continues into the third decade of life and both influences and is affected by, health and illness (including rheumatic disease) during this time. Effective transitional care in rheumatology is underpinned by the core principles of adolescent medicine, self-management of long-term conditions, and a youth-friendly rheumatology service including staff trained in adolescent health.
