Factors Influence Internal Audit Effectiveness
Authors: Shamki Dhiaa , Amur Alhajri Thuraiya
Published: September 2017

This study aims to examine to what extent internal audit effectiveness could be influenced by selected factors namely internal audit scope, internal auditor’s experience and senior management's response in the Omani public sector. Employing questionnaire including four sections with 48 questions for responds of 45 managers and 163 employees in Public Authority for Social Insurance (PASI) in the Sultanate of Oman, descriptive analysis, correlation analysis, and multiple regressions were employed to examine the relationships among the study’s variables. The study found that a significant relationship between internal audit effectiveness and its scope and auditors’ experience in the employees’ sample while they were insignificant in the managers’ sample. Finally, it is found that there is insignificant relationship between internal audit effectiveness and senior management's response. Based on the findings, an awareness has to be maximized on employees to better cooperate with internal audit staff to improve the applications of internal audit standards. Managers are well interested in organization’s activities and performance depending on the internal audit findings and observations. The board of directors has to take in its considerations the reasons of these insignificant results if the reasons are not related to the small size of the managers’ sample. The study’s contribution is to provide evidence regarding the influence of three mentioned factors on the internal audit effectiveness in public sector.

Factors Affecting Management Accounting Practices in Malaysia
Authors: Nair Sudhashini , Soon Nian Yee
Published: September 2017

Management accounting is the process of preparing management reports and accounts that provide accurate and timely, financial and statistical information to assist in management decision making. It is also known as the process of identifying, measuring, accumulating, analyzing, preparing, interpreting and communicating information to help managers fulfill the organization’s objectives. Management accounting practices are used by organizational managers at various levels and at the same time, it gives managers the freedom of choice as there are no constraints, other than the cost of information collected relative to benefits of improved management decisions. Studies have found that there are factors that may affect management accounting practices. Literature has indicated that factors such as--organization size, intensity of market competition, level of qualification of accounting staff and advanced production technology--may affect management accounting practices. The objective of this research is to study the impact of these factors on management accounting practices in Malaysia. A total of 200 respondents from Klang Valley, Malaysia were involved in the survey using purposive sampling. The results of the study revealed that organization size and advanced production technology have significant relationships with management accounting practices.

Authors: Wang Xia , Tong Luqiong
Published: September 2017

China is fast becoming one of the most important luxury goods market. The purpose of this study is to investigate the determinants of luxury purchasing behavior in the Chinese affluent market. Based on the logit analysis of 618 affluent respondents, the results show that social-adjustive motivation and life satisfaction are significantly associated with the purchasing of luxuries. However, the value-expressive motivation, which has been verified that could drive the consumer buy luxury items, does not have significant effect on luxury purchasing behavior for the Chinese affluent consumers. In the meantime, the demographic characteristics of individual are significantly associated with his/her luxury purchasing behavior, and the younger affluent consumers with higher income and international education are more likely to buy more luxuries. It helps researchers and companies to understand the differences of the factors influencing luxury consumption between Chinese consumers and their global peers.

Authors: Gunaratne Yathra Mullage Chithrasheeli , Anuradha P. A. Niluka Surangi
Published: September 2017

The value relevance of accounting information is an important area in accounting researches. However the literature provides contradictory conclusions on the value relevance of accounting information in different stock exchanges and there is a very limited knowledge in this regard in Sri Lankan context. Hence this study endeavored to investigate the value relevance of accounting information in explain stock returns considering three traditional accounting performance measures: Earnings Per Share (EPS), Return on Equity (ROE) and Return on Investment (ROI) as the proxy for accounting information. The study was conducted with the hypothesis that the traditional accounting performance measures are significant in explaining stock returns in Sri Lanka. A sample of 1695 firm year observations were used for the study covering 113 companies in Colombo Stock Exchange for fifteen years period from 1999 to 2013. This study used Easton and Harris (1991) formal valuation model. Panel data regression analysis technique was applied to test the relative information content of each performance measure to identify the best performance measure which could explain the stock returns in Sri Lanka. The study revealed that the EPS and ROI are significant performance measures and the EPS is the best performance measure which could explain the significant variations of stock returns in Sri Lanka. The results suggest that the market participants in the Colombo Stock Exchange should pay more attention on EPS and ROI. Meantime they must consider other determinants to develop their investment strategies.
Effect of Financial Literacy on Retirement Preparedness among Employees in the Insurance Sector in Kenya
Authors: Aluodi Emma , Njuguna Amos , Omboi Bernard
Published: September 2017

The failure to comprehend financial matters has been considered the main reason behind retirement problems faced by many individuals. Insurance firms being dominant private player in retirement; the universal assumption is that its’ employees have more knowledge of the pension systems and how it affects them. It is equally assumed that these employees are perfectly informed and rely on accurate knowledge regarding their likely retirement benefits and consumption needs and therefore able to arrive at an optimal savings decisions and make better choices for their retirement. This study dissipates this notion after investigating the effect of financial literacy on retirement planning by employees in the insurance sector in Kenya. Using explanatory research design, the study employed stratified proportionate random sampling method to select the respondents. Data was collected using questionnaires and analysed by use of one way ANOVA and Pearson correlational analysis. Hypotheses were tested by use of both, multiple linear regression and multinomial logistic regression. The study reveals that financial literacy has no significant effect on retirement preparedness. This finding offers great insights and implication in policy making for both the government and institutions reforms.
Conceptualizing Relational Resources as Critical Factor for IT Outsourcing Success
Authors: Popoli Paolo
Published: September 2017

The relational resources represent key assets for outsourcing success. Achieving full potential in the development and exploitation of relational resources in outsourcing can be understood as occurring in two closely intertwined phases: i. during the choice of the provider; ii. through the governance of the relation that develops over the execution of the contract. The current paper aims to provide conceptual insights into these two phases, as they apply to the particular area of companies’ IT outsourcing. A first objective is to illustrate the role of relational resources in determining the ultimate degree of success in IT outsourcing and to discuss its potential as an “instrument to address risk”. A second objective is to outline managerial criteria for correct choice of the IT provider and for appropriate direction of client-vendor relations over the course of the resulting contract execution. The main findings of this study show that the paradigmatic shift from a transaction-based outsourcing to a partnership-based outsourcing gives centrality to the contract management and on-going management. On this point, relational resources have become a critical factor for IT outsourcing success, and they have to be considered as a tool to address the risks of IT outsourcing. Concerning the managerial implications the main finding is the need to use the “relational requisites” rather than “subjective requisites” in the evaluation and choice of potential IT provider.
The Value of Corporate Social Performance: The Case of a Local Public Transport Company
Authors: Francesco Agliata , Ferrone Caterina , Tuccillo Danilo
Published: September 2017

The Corporate Social Responsibility is traditionally viewed not as a productive investment, but like an expense of defensive character, destined to consume resources without producing new value. However, in the actual context, the public interest cannot be an objective only for the Public Administration; each enterprise should integrate in the management choices a CSR strategy (Borgonovi & Rusconi, 2008).The CSR is, primarily, intended as the ability to follow those lines of action which are desirable in relation to the aims and values of our society (Bowen, 1953). The development of studies on CSR has produced subsequently further definition, which tend to emphasize the importance of expectations of the community and the resulting social role played by itself in increasing weal (Frederick, 1960); to the definition of corporate social responsibility contained in the EU Green Paper, which identifies CSR as those behaviours oriented to the integration between economic, social and environmental variables in the management company (EU, 2001).This work aims to investigate the potential of investment in CSR in terms of creating new value as part of a new definition of sustainable business performance based on the joint and balanced maximization of economic, social and environmental objectives (Elkington, 1997). The objective of this research is to verify the impact on business performance due to the implementation of a specific design of CSR, named Contact, in a local public transport company of medium/big size (Turnover € 56.613.130, Employees 1.341).
Comments on a Two Queue Network
Authors: Morin Samantha , Hlynka Myron , Xu Shan
Published: September 2017

A special customer must complete service from two servers, each with an $M/M/1$ queueing system. It is assumed that the two queueing systems have initiial numbers of customers $a$ and $b$ at the instant when the special customer arrives, and subsequent interarrival times and service times are independent. We find the expected total time (ETT) for the special customer to complete service. We show that even if the interarrival and service time parameters of two queues are identical, there exist examples (specific values of the parameters and initial lengths a and b) for which the special customer surprisingly has a lower expected total time to completion by joining the longer queue first rather than the shorter one.

Leptospirosis is a common disease between humans and animals. Identifying common serogroups and comparing different clinical symptoms among them can help in finding the clinical pattern associated with pathogen serogroupes of leptospirosis. Therefore, the purpose of this study has been to investigate the common serotypes of the infection and their clinical symptoms in northern Iran. This cross-sectional study was carried out in educational hospitals of Babol University of Medical Sciences during the years 2011- 2014. Subjects with clinical findings consistent with leptospirosis were included in the study. According to the standard MAT guidelines, the titre >=1: 200 was considered positive. Then, the patients identified by serogroup separation, were examined and compared clinical symptoms. Among 6o patients with primary diagnosis of leptospirosis in this study, 35 of them proved to be infected to the disease. The most common serogroups were serjoe (40%) and icterohemorrhagia (31.4%). Autumnalis (22.8%), grippotyphosa (11.4%), canicola (8.6%), and pomona (2.8%) were included the subsequent serogroups. The highest frequency of fever (28%) and gastrointestinal manifestations (36%) were observed in icterohemorrhagia and the highest icterus (30%) was found in serjoe serogroup. In this study, serjoe serogroup with fever and icterus, and then icterohemorrhagia with fever and gastrointestinal symptoms were introduced as the most common serogroups of Leptospirosis. Also the rarest serogroups were canicola and pomona.

Authors: Rymarczyk Tomasz , Tchórzewski Paweł , Sikora Jan
Published: September 2017

The boundary element method and the level set method can be used in order to solve the inverse problem for electric field. In this approach the adjoint equation arises in each iteration step. Results of the numerical calculations show that the boundary element method can be applied successfully to obtain approximate solution of the adjoint equation. The proposed solution algorithm is initialized by using topological sensitivity analysis. Shape derivatives and material derivatives have been incorporated with the level set method to investigate shape optimization problems. The shape derivative measures the sensitivity of boundary perturbations. The coupled algorithm is a relatively new procedure to overcome this problem. Experimental results have demonstrated the efficiency of the proposed approach to achieve the solution of the inverse problem.

About graptolite genus Lithuanograptus once more
Authors: Paškevičius Juozas
Published: September 2017

A new genus of graptolites named Lithuanograptus has been found in Lithuania and studied by the present author (Paškevičius, 1972, 1976) in the Silurian Llandovery cyphus zone of the Rasytė Formation and the following 4 species have been described: L. fusiformis Pašk., L. obuti Pašk., L. minimus Pašk. and L. serus Pašk. Loydell (1992) treated this genus as a junior synonym of Metaclimacograptus and attributed the species of L. minimus and L. serus to this genus. The author of the present paper agrees to the attribution of these species to the genus Metaclimacograptus. Nevertheless, a genotype L. fusiformis of Lithuanograptus and its species L. fusiformis and L. obuti differ significantly from Metaclimacogratus by fusiform rhabdosome, massive virgella and structure of thecae – a flattened geniculum surrounding and fully covering the thecal excavations, types of medial and interthecal septa and other features. Therefore, the author considers Lithuanograptus with L. fusiformis and L. obuti being separate genus and species. Moreover, the paper presents the holotypes of the mentioned two species with the material, diagnosis, age and detection sites.
Memorialization of Maironis with Respect to Literary Canonization (1932–1940)
Authors: Šeina Viktorija
Published: September 2017

The paper focuses on the performative and material memorialization (anniversaries, funeral, obituaries in the press, the gravestone, and the memorial museum) ofMaironis (Jonas Mačiulis, 1862–1932) in the 1930s, which contributed to the consolidation of the poet’s position in the national literary canon. It also describes what prevalent meanings of his literary works were being formed by different practices of memorialization.
When Maironis died in 1932, the press was full of obituaries, detailed commentaries, and interpretations of his funeral. We also have a script of his 70th birthday celebration, which, together with the mentioned acts of memorialization, shows that Maironis occupied the central spot in the national literary canon in the early 1930s. The very fact of his death granted an additional motive towards a faster canonization of the poet and served as a base to form Maironis’s patriotic cult. In the obituaries, the meaning of Maironis’s poetry was predominantly judged from the point of view of its social and historical impact and Maironis was extolled as a prophet of the national revival who had awakened the Lithuanians to the fight for their language, culture, and statehood. During the interwar period, the era of the national revival had become an essential place of collective memory in general, thus the poetry of Maironis, who had already been treated as the national poet of the revival, was recognized not only as a witness of that epoch, but also as the one that could fulfill the vitally important function of mobilization of the community and of the formation of national and civil identity.
When Maironis was still alive, he was commemorated in various toponyms of Kaunas and other regions of Lithuania. After his death, the importance of his memorialization in different ways became obvious. Shortly after his funeral, the publication of memoirs about his life, stories about the processes of writing poetry, and his letters was initiated. In the late 1930s, a mausoleum of Maironis was built near Kaunas Cathedral Basilica, a bust of Maironis was erected in the square of the Military Museum of Vytautas the Great, and Maironis Memorial Museum was founded. There were no other Lithuanian writers in the period of the Republic of Lithuania (1918–1940) who received so much attention from the state and so much financial support as was assigned to the memorialization of Maironis.
Early Socialization of the Child: Cultural Aspects of Childcare in Twenty-First-Century Lithuania
Authors: Daraškevičienė Audronė
Published: September 2017

Drawing on cultural perspectives of childcare, the aim of this paper is to explorethe childcare culture in twenty-first-century Lithuania. The main objectives are as follows: to discuss childcare models in the society of contemporary Lithuania, to reveal early socialisation goals, to analyze how childcare models can be shaped by the cultural context. My descriptions of the childcare in contemporary Lithuania are based on ethnographic ﬁeldwork conducted from 2013 to 2016.
Two main childcare models can be observed in twenty-first-century Lithuania. According to the sociologist Petra Büskens, one of them can be called the romantic childcare model (childcare practices: one-to-three years of unregulated breastfeeding, “in arms” or “baby-wearing” practice, the family bed with emphasis on the child’s needs). Proponents of the rational childcare model have a more critical opinion on breastfeeding and “baby-wearing”, and their babies sleep in a separate bed. Proponents of rational childcare tend to emphasize the parents’ and not the baby’s interests.
Proponents of different childcare models pose different goals of child socialisation. The landmarks of child socialisation for the adherents of the romantic childcare model are the child’s psychological security and strong family ties. Proponents of the rational childcare model advocate the child’s adjustment to other people’s interests as the main aim of early socialisation of the child.
The material of ethnographic ﬁeldwork in contemporary Lithuania supports the researchers’ view that the character of childcare is associated with a broad cultural context that is expressed through parents’ worldview. In contemporary Lithuania, the proponents of the romantic model associate childcare with social power or acquisition of the socially relevant qualities. For them, “natural” is “what is close to nature”. They reject the more structured childcare practices, equating them with human constraints which for them are a symbolic representation of the Soviet times. Meanwhile, the proponents of the rational childcare model do not tend to impart much meaning of social power to childcare. “Natural” or “normal” practices for them are those which do not create problems for adults. Proponents of rational childcare equate the more structured childcare practices not with the Soviet times, but with the tradition of their grandparents and parents.
The study supports the researchers’ assumption that taking care of an infant is associated with a much broader circle of issues than health and feeding. The meanings of childcare practices are influenced by the fundamental cultural contexts such as those which define the concept of the person, the relation of the man and the woman to nature, social priorities, and the socially accepted concept of time.

Published: September 2017

La  formación  del  profesorado  en  el  uso  de  las  TIC  es  un  aspecto  importante  para  conseguir  una verdadera integración de las TIC en la educación. Según el modelo TPAK, esta formación no debe limitarse  a  contemplar  de  manera  separada  los  aspectos  relacionados  con  las  TIC,  el  contenido curricular y la metodología. En el presente estudio se explora la percepción de autoeficacia en cuanto al uso de las TIC en el aula de una muestra de 107 estudiantes de los grados de Maestro/a en Educación Infantil y Maestro/a en Educación Primaria. Para ello se emplea una traducción del cuestionario para la autoevaluación de las competencias TIC elaborado por Tondeur et al. (2016). Los resultados del estudio muestran que los estudiantes de Magisterio se perciben a sí mismos como más competentes en el uso de las TIC que en la toma de decisiones pedagógicas relacionadas con dicho  uso.  Además,  se  halló  una  correlación  estadísticamente  significativa  entre  las horas de formación recibidas en el uso educativo de las TIC y la percepción de autoeficacia en este mismo uso educativo de las TIC. Estos resultados conllevan algunas implicaciones en la toma de decisiones respecto a la formación del profesorado.

Published: September 2017

The dynamics of conflict in Syria has influenced the energy security in the region. United States and Europe both have strategic interests on Syrian for securing the flow of oil and gas from the Middle East to Europe and preserving peace and harmony in the region. This article contends that Syria plays a strategic role in maintaining the stability of oil production from the Middle East. Even though the production of oil in Syria declined drastically from 400,000 barrell per day to 25,000 barrell per day, but most of those products are at the hand of opposition, including the jihadist of ISIS, in the Northern and Southern area of Syria. In addition, the presence of foreign fighters in Syrian civil war have fueled the conflict and affected the stability of the region. Syria needs at least 30 years to recover from current conflict and it needs oil productions as the vital factor. This article is based on interviews conducted in 2012 to 2013 in Jakarta and analysis of documents.
The GMD Method for Inductance Calculation Applied to Conductors with Skin Effect
Authors: Aebischer H. A. , Aebischer B.
Published: September 2017

The GMD method (geometric mean distance) to calculate inductance offers undoubted advantages over other methods. But so far it seemed to be limited to the case where the current is uniformly distributed over the cross section of the conductor, i.e. to DC (direct current). In this paper, the definition of the GMD is extended to include cases of nonuniform distribution observed at higher frequencies as the result of skin effect. An exact relation between the GMD and the internal inductance per unit length for infinitely long conductors of circularly symmetric cross section is derived. It enables much simpler derivations of Maxwell’s analytical expressions for the GMD of circular and annular disks than were known before. Its salient application, however, is the derivation of exact expressions for the GMD of infinitely long round wires and tubular conductors with skin effect. These expressions are then used to verify the consistency of the extended definition of the GMD. Further, approximate formulae for the GMD of round wires with skin effect based on elementary functions are discussed. Total inductances calculated with the help of the derived formulae for the GMD with and without skin effect are compared to measurement results from the literature. For conductors of square cross section, an analytical approximation for the GMD with skin effect based on elementary functions is presented. It is shown that it allows to calculate the total inductance of such conductors for frequencies from DC up to 25 GHz to a precision of better than 1 %.

With 600 described species, the ant genusTetramoriumrepresents one of the most species-rich ant radiations. However, much work remains to fully document the hyperdiversity of this remarkable group.Tetramorium, while globally distributed, is thought to have originated in the Afrotropics and is particularly diverse in the Old World. Here, we focus attention on theTetramoriumfauna of India, a region of high biodiversity value and interest for conservation. We overviewTetramoriumdiversity in India by providing a species list, accounts of all species groups present, an illustrated identification key to IndianTetramoriumspecies groups and notes on the IndianTetramoriumfauna. Further, we describe two new species,Tetramorium krishnanisp. n. andTetramorium jarawasp. n. from the Andaman Islands archipelago and embed them into currently recognizedTetramorium tonganumandTetramorium inglebyispecies groups. We also provide illustrated species level keys for these groups. Along with detailed species descriptions and high-resolution montage images of types, we provide 3D cybertypes of the new species derived from X-ray micro-computed tomography.

Key Points

We characterize key deep uncertainties surrounding flood risk projections for a levee ring in New Orleans using 18 probabilistic scenarios

The levee system alone may provide flood protection between the 100‐ and 500‐year return period

Uncertainty in the storm surge distribution shape parameter is the primary driver of flood risk variability

Magnetosheath plasma usually determines properties of asymmetric magnetic reconnection at the subsolar region of Earth's magnetopause. However, cold plasma that originated from the ionosphere can also reach the magnetopause and modify the kinetic physics of asymmetric reconnection. We present a magnetopause crossing with high‐density (10–60 cm−3) cold ions and ongoing reconnection from the observation of the Magnetospheric Multiscale (MMS) spacecraft. The magnetopause crossing is estimated to be 300 ion inertial lengths south of the X line. Two distinct ion populations are observed on the magnetosheath edge of the ion jet. One population with high parallel velocities (200–300 km/s) is identified to be cold ion beams, and the other population is the magnetosheath ions. In the deHoffman‐Teller frame, the field‐aligned magnetosheath ions are Alfvénic and move toward the jet region, while the field‐aligned cold ion beams move toward the magnetosheath boundary layer, with much lower speeds. These cold ion beams are suggested to be from the cold ions entering the jet close to the X line. This is the first observation of the cold ionospheric ions in the reconnection outflow region, including the reconnection jet and the magnetosheath boundary layer.
Out of the woods: Driftwood insights into Holocene pan‐Arctic sea ice dynamics
Authors: Hole Georgia M. , Macias‐Fauria Marc
Published: September 2017

The collation of 913 driftwood samples from across the western Arctic, with spatiotemporal distribution and available provenance data, enabled the production of a high‐resolution proxy‐based reconstruction of Holocene Arctic Ocean surface current and sea ice dynamics. Regionally bounded, driftwood‐based sea ice reconstructions studies suggest spatiotemporally complex past Arctic sea ice extent and movement; however, a large‐scale compilation of Holocene Arctic driftwood has not previously been developed. Sparse driftwood in the early Holocene (≥8.2 cal ka B.P.) deglacial period was followed by increased driftwood deposition in the warmer mid‐Holocene (8.2–4.2 cal ka B.P.); characterized by an enhanced Transpolar Drift (TPD) ∼7 cal ka B.P., leading to sea ice loss through the Fram Strait. Driftwood incursion peaks show spatial E‐W progression from the Eurasian Archipelagos to Greenland and the Canadian Arctic Archipelago, suggesting a progressive shift in the orientation of the TPD on centennial‐millennial time scales and intermediate phases in the Arctic Oscillation. Late Holocene cooling (≤4.2 cal ka B.P.) is indicated by increased influx of probably North American Picea via a strengthened Beaufort Gyre (BG) which enhanced sea ice recirculation, starting in the western Arctic and progressing eastward. In recent millennia (<2 cal ka B.P.), a more variable driftwood record alternates between BG and TPD dominance on centennial time scales. To further constrain a spatiotemporal reconstruction of variations in Holocene ocean current and sea ice dynamics, a more definitive determination of driftwood provenance is recommended to build upon the current framework, such as through radiogenic isotope tracing and aDNA analysis.

Anti‐Icing Performance of Superhydrophobic Texture Surfaces Depending on Reference Environments

Published: September 2017

Materials decorated by the hierarchical micro‐nanostructures similar to lotus leaf surface topographies are firmly considered to possess the substantial anti‐icing functions, showing icing‐delay and low ice adhesion. Here, the aim of this work is to verify the anti‐icing capacity in the actual icing environment containing supercooled airflow. This study, therefore, develops both routes to fabricate the hierarchical micro‐nanostructure and single nanostructure superhydrophobic surfaces, and first evaluates their anti‐icing capacity based on the routine measuring strategies in laboratory. Also, the potential application environment is modeled and used to verify their anti‐icing performance for further guiding rational design of surface structures of anti‐icing materials. Due to the double‐scale effect, the hierarchical micro‐nanostructure can induce more air pockets to produce the higher hydrophobicity and anti‐icing capacity based on the big reference droplets (diameter > 2 mm) and even static water. However, the verified results in the potential application environment demonstrate that the hierarchical micro‐nanostructure exhibits the inferior anti‐icing performance, comparing with the single nanostructure. The icing area on the single nanostructure surface is almost half of that on the hierarchical micro‐nanostructure surface, also causing a reduction of ≈26 g in icing mass.
