Spectral Responses

This study provides an evaluation of spectral responses of hollow ways in Upper Mesopotamia. Hollow ways were used for the transportation of animals, carts, and other moving agents for centuries. The aim is to show how the success of spectral indices varies in describing topologically simple features even in a seemingly homogeneous geographic unit. The variation is further highlighted under the changing precipitation regime. The methodology begins with an exploration of the relationship between the date of a multispectral scene and the visibility of hollow ways. The next step is to evaluate the impact of rainfall levels on numerous indices and to quantify spectral contrast. The contrast between a hollow way and its background is evaluated with Welch’s t-test and the association between precipitation regime and spectral responses of hollow ways are investigated with Correspondence Analysis and Fisher’s test. Results highlight an intrinsic relationship between the precipitation regime and the ways in which archaeological features reflects and/or emits electromagnetic energy. Next, the categorization of spectral indices based on different rainfall levels can be used as a guidance in future studies. Finally, the study suggests contrast becomes an even more fruitful concept as one moves from the spatial domain to the spectral domain.

PurposeThe purpose of this paper is to explore the impact of organisational culture on productivity and quality in software organisations, with special reference to India.Design/methodology/approachThe empirical study was done in two phases. The first phase adopts qualitative methodology and examines the significant aspects of organisational culture, productivity, and quality and the nature of the relationship organisational culture has with productivity and quality. The second phase makes a quantitative analysis of this relationship.FindingsThe study develops a range of insights into the way cultural processes tend to influence productivity and quality in people centric and knowledge intensive work contexts such as software.Research limitations/implicationsThis study employed perceptual measures of productivity and quality in the quantitative analysis. Future studies can develop objective criteria, which would facilitate robust quantitative analysis. Future studies should also explore whether the findings of this study have generalisability beyond the Indian context.Practical implicationsThe study provides insights into the management of productivity and quality in contexts where work is characterised by high levels of abstraction and invisibility.Originality/valueThere are very few empirical studies on this relationship in dynamic and sophisticated work contexts such as software and this further contributes to the debate concerning the impact of organisational culture on effectiveness.

The Relationship

In this paper we study the relationship between oil prices and macroeconomic performance by investigating the impact of oil price shocks on key macroeconomic variables of Vietnam over the 2001–2012 period. In order to test the relationship between oil prices and the value of industrial production, we use cointegration method to consider the long-term relationship and Error Correction Model (ECM) to ponder the short-term one. The test results show that the price of oil and the value of industrial production in Vietnam are positively correlated in the long term, whereas in the short term the volatility of oil prices in the last two months will negatively affect the fluctuation in the value of the current industrial production.

The purpose of the paper is to determine the relationship between different types of tourism safety and security, and components of the tourism entrepreneurship potential, to conduct a quantitative analysis of these indicators in the regions of Ukraine and to identify areas for ensuring the safety and security of the tourism entrepreneurship potential realization. Methodology. Analysis of tourism safety and security in Ukraine is based on the assessment of security potential indicator and the security threats indicator for 25 regions. These indicators take into account the following types of safety and security: security of tourist services, safety of tourist facilities and equipment, social security, political security, financial security, medical safety, information security, and ecological security. The impact of tourism safety and security on the tourism entrepreneurship potential realization is determined on the basis of correlation and regression analysis, where the indicator of the tourism entrepreneurship potential realization is the volume of domestic and inbound tourist flows in the region. The empirical basis of the study is the data of the State Statistics Service of Ukraine for 2019. The reliability of the regression model was tested on the basis of the approximation coefficient and Fisher's F-test. Results of the correlation analysis indicate a significant relationship between ensuring the safety and security of tourism in the region and the volume of domestic and inbound tourist flows. As a result of regression analysis, a model of a high level of reliability was obtained, which indicates how the volume of domestic and inbound tourist flows to the region increases with increasing the level of tourist safety and security by unit. Practical implications. Since the process of safety and security ensuring for the tourism entrepreneurship potential realization cannot be implemented exclusively at the regional level, it is justified the feasibility of a targeted public policy in eight areas. Value/originality. The identified relationship between the types of safety and security of tourism and components of the tourism entrepreneurship potential, as well as establishing the level of impact of safety and security of tourism on the tourism entrepreneurship potential realization in the region provide for a better understanding of ways for efficient governance in this area.

Introduction: The MoCa (Montreal Cognitive Assessment) Screening test has become relevant in recent years in the screening of patients with Mild Cognitive Impairment (MCI). It is important to seek and study simple and reliable tools in clinical practices that correlate with biological markers that have been used to predict conversion from MCI to AD. Objective: To analyze the MOCA and its cognitive sub-scores and the relationship with Amyloid pathophysiology in Alzheimer’s Disease. Methodology: 32 patients with MCI were studied, they were separated according positive (n: 20) and negative (n: 12) underlying amyloid pathology. The patients performed a extensive cognitive assessment that included MoCa Test. Results: MoCa Total Scores showed significantly different results between groups (p <0.001) as well as the Memory Score (MoCa MIS), the Executive (MoCa EIS), the Attentional Score (MoCa AIS)) (p < 0.001) and the Orientation Score (MoCa OIS)) (p < 0.05) with worse performance of patients with amyloid pathophysiology. Score of MoCa a cut-off point of < 24 was established, since the diagnostic sensitivity at this point was 83% and the specificity 70%. Conclusions: The MoCa is a useful tool to differentiate biomarker status in MCI. Future studies should study this tool in the prodromal phases of the disease.

PurposeBased on mental accounting theory, this study explored whether the comparability of missed and subsequent promotional formats/frames affects inaction inertia.Design/methodology/approachFour experiments with imaginary and incentive-compatible designs were conducted to test the hypotheses.FindingsConsumers are more likely to express inaction inertia after having missed a comparable promotion than after having missed a noncomparable promotion. Devaluation of the promoted target mediates the impact of comparability on inaction inertia, while referent others' actions do not moderate the comparability effect. Finally, when consumers accept a subsequent inferior promotion, they prefer using a different payment format because it reduces comparability of the two promotions.Practical implicationsCompanies should use different promotional formats/frames to reduce comparability and inaction inertia when a new promotion is relatively inferior to a recent previous one. Companies should offer different payment options to help customers actively avoid comparing a current promotion with a missed promotion.Originality/valueThis study provides a more comprehensive conceptual structure for understanding the relationship between psychological comparability and inaction inertia. It provides insights into what actions companies should take to reduce inaction inertia. Furthermore, this study empirically tests the influence of multiple comparison referents, which provides a reference point for future studies on the factors affecting inaction inertia. A new method to examine whether consumers actively avoid comparisons is used, which clarifies the internal mechanism of inaction inertia.

This study aimed to investigate the impact of individual differences in mindfulness on nomophobia. We developed and validated two structural models to identify the relationship between mindfulness and nomophobia. The ‘Nomophobia Questionnaire’ and the ‘Mindful Attention Awareness Scale’ were used to obtain data from the subjects. One-way MANOVA results suggested a statistically significant difference in nomophobia based on higher versus lower mindfulness. Further, a multi-group analysis was conducted to test the hypothesized relationships in the structural models for men and women. The results revealed that mindfulness had a significant negative correlation with nomophobia for both men and women. As scores in mindfulness increased, subjects exhibited less nomophobic tendencies. Further, those subjects who had lower scores in mindfulness showed higher anxiety when they were unable to communicate. However, subjects who scored higher in mindfulness showed lower anxiety when they could not access desired information. Independent sample t-test results were variant across men and women in nomophobia. Based on the findings we conclude that mindfulness based treatments can be beneficial in dealing with nomophobia for women.

This study investigated the effect of collaborative tasks on language performance, with a focus on fluency and accuracy. Three groups of Saudi learners of English in a secondary school were given either awareness raising tasks, meaning-based activities or a combination. Quantitative data collected from 72 Saudi learners of English and then analysed to answer the research questions. The test results were analysed for speech fluency, written fluency, accuracy and lexical richness to provide quantitative measures of any improvement over the three test periods. Consideration was also given to language related episodes (LREs), i.e. pauses, repetitions and self-correction to identify changes during the interactions. The results indicated that there was an improvement in both fluency and accuracy. In addition, there is a likely significant benefit of encouraging interaction amongst peers during a task-based learning approach, particularly when there is a combination of CT and CR tasks, when compared to one task type. The findings underline the relationship between classroom interaction and practice and improvements in fluency and accuracy. This is important due to the increasing view that in the teaching of EFL, fluency is being neglected despite its importance in achieving communicative competence as Tavakoli and Hunter (2018) noted. As a result of the findings we argue that Saudi secondary school EFL classes should place a greater emphasis on TBL and interaction, combining both consciousness raising and communicative tasks to maximise the improved benefits seen in this study.

This study aims to investigate methods of achieving an integrating relationship between internal and external audit when conducting audit procedures in Jordanian public shareholding corporations, as well as investigate the impact of audit committees achieving such a relationship since an effective internal audit effective  the external auditor`s estimations regarding control risks. The study concludes that all aspects of the realization of an integration relation between internal and external audit have achieved a fair ratio exceeding 60%. Spearman test was used to show the nature of the relationship between the internal and external audit. The test results showed that the relationship between these methods is vulnerable in Jordanian public shareholding corporations, and that audit committees have no statistically significant impact on achieving an integrating relationship between internal and external audits  in conducting audit in Jordanian public shareholding corporations, since the ratio of audit committees interpretation (R2) which amounted to (.145) of the dependent variable difference ( achieving an integrating relationship between internal and external audit in conducting audit) is relatively low, and that the P- value derived for this relation amounted to (.615) which is more than (5%) .

ABSTRACT Prior research has shown that the implementation of ERP systems can significantly affect a firm's business operations and processes. However, scant research has been conducted on the relationship between ERP implementation and the timeliness of external audits, such as audit report lags. While some of the alleged benefits of ERP are closely related to removing impediments contributing to audit report lags, others argue that the complex mechanisms of ERP systems create greater complexity for control and audit. In this paper, we examine the relationship between ERP implementations and audit report lags. The test results indicate that overall, a firm's ERP implementation is negatively associated with audit report lag. However, this negative association is significant only at the fourth and fifth years after initial ERP implementation. These results imply that the use of ERP systems by client firms may help decrease the audit report lag, but it takes time for the full impact of the firms' accounting systems to be realized.
