Abstract

Purpose

This study aims to examine the effects of pharmacy service factors (namely, medication teaching, service promptness, pharmacist attitudes, medication supply and pharmacy location) on patient satisfaction with community pharmacies in Jordan and to explore the effect of patient satisfaction on pharmacy performance.

Design/methodology/approach

Descriptive analytical methodology, with a quantitative approach using survey strategy was applied. The study population represented the whole population of Jordan (2.033 million households). Data were collected using an online questionnaire. A convenient quota sample of 1,000 respondents was targeted; 502 valid questionnaires were returned, representing an effective response rate of 50.2%. The study hypotheses were tested using path analysis.

Findings

The results showed that the service factors contributing most significantly to patient satisfaction in Jordan are medication supply, pharmacist attitudes, medication teaching and service promptness, in descending order of influence. Meanwhile, the effect of pharmacy location on patient satisfaction proved to be insignificant. In addition, patient satisfaction proved to have a highly positive impact on pharmacy performance.

Originality/value

This study addresses a debatable issue in the literature regarding the influence that pharmacy service factors can have on patient satisfaction. In addition, to the best of the researchers’ knowledge, this is the first study to explore the proposed effects in Jordan. It is also one of the first to investigate the effect of patient satisfaction on community pharmacy performance.

Abstract

Purpose

Niobium Nitride (NbN) was interesting material for its applications in the medicinal tools or tools field (corresponding to saline serum media) as well as in mechanical properties. The aim of this work was depositing NbN thin films on two types of substrates (stainless steel (SS304) and silicon (100)) using plasma technique at varied powers (100–150 W).

Design/methodology/approach

DC magnetron sputtering technique at different powers were used to synthesis NbN films. Film structure was studied using X-ray diffraction (XRD) pattern. Rutherford elastic backscattering and energy dispersive X-ray were used to examine the deposited film composition. The films morphology was studied via atomic force microscopy and scanning electron microscopy images. Corrosion resistance of the three NbN/SS304 films was studied in 0.9% NaCl environment (physiological standard saline).

Findings

All properties could be controlled by the modification of DC power, where the crystallinity of samples was changed and consequently the corrosion and microhardness were modified, which correlated with the power. NbN film deposited at higher power (150 W) has shown better corrosion resistance (0.9% NaCl), which had smaller grain size (smoother) and was thicker.

Originality/value

The NbN films have a preferred orientation (111) matching to cubic structure phase. Corrosion resistance was enhanced for the NbN films compared to SS304 substrates (noncoating). Therefore, NbN films deposited on SS304 substrate could be applied as medicinal tools as well as in mechanical fields.

Abstract

Purpose

TiN and TiAlVN films have been prepared by DC magnetron sputtering technique at room temperature. TiN target has been used to deposit TiN thin film under pure argon (100 percent Ar) gas. Additionally, Ti6Al4V alloy target has been used to deposit TiAlVN under nitrogen and argon gas (50 percent Ar and 50 percent N2). In this paper, two substrate types have been used: stainless steel 304 and Si(100). This analysis has confirmed that the nitride films, (TiN/Si) and TiAlVN in both cases, have been produced. Energy Depressive X-ray Spectroscopy (EDX) measurement confirmed that the TiN/Si was stoichiometry, where the N/Ti ratio was about 1 with low oxygen contamination. The results obtained have indicated that the TiAlVN has more resistance to corrosion than TiN film in 3.5 percent NaCl at 25°C (seawater). Both films, TiAlVN/SS304 and TiN/SS304, have shown improved corrosion resistance compared with virgin 304 substrate. Microhardness was carried out using Vickers method; the microhardness values for TiN/SS304 and TiAlVN/SS304 were approximately 7.5 GPa and 25.3 GPa, respectively. The paper aims to discuss these issues.

Design/methodology/approach

The films were prepared by a DC magnetron sputtering system starting from high pure (99.99 percent) Ti6Al4V target (Al 6wt%, V 4wt% and balance Ti) in plasma discharge argon/nitrogen (50 percent Ar and 50 percent N2) for deposition of TiAlVN film. Pure TiN target (99.99 percent) was used for preparation of TiN film in pure argon plasma. The diameter of target was 50 mm and the power applied for preparation of the two films was 100 W. A cylindrical high-vacuum chamber (Figure 2) made of stainless steel 316, with height 363 mm diameter, was fabricated locally. Scanning electron microscope images have been used to discover the films morphology. The composition of the films has been determined by EDX technique for films deposited on Si substrate. The electrochemical corrosion test was carried out using conventional three-electrode cell of 300 ml capacity by using Voltalab PGZ 301 system (France) using Tafel extrapolation method and electrochemical impedance spectroscopy techniques.

Findings

TiN and TiAlVN films have been prepared by DC magnetron sputtering technique without heating of the substrates holder. The effects of the composition of nitride films on mechanical and corrosion properties were investigated. The composition of the films has been determined by EDX technique. The effect of using titanium alloy (Ti with Al and V) on the composition and crystalline quality has been investigated. The microhardness is strongly dependent on the addition of the Al and V elements, and it consequently improves mechanical proprieties. The microhardness values for TiN/SS304 were approximately 7.5 GPa and 25.3 GPa for TiAlVN/SS304. They indicate that prepared films prevent the aggressive action of corrosion media.

Originality/value

TiN and TiAlVN films have been prepared by DC magnetron sputtering method at room temperature. Titanium nitride film, especially TiAlVN, is an effective method to improve the corrosion resistance of SS304. TiAlVN film has exhibited enhanced corrosion resistance and higher microhardness. Independent time-of-flight elastic recoil detection analysis has been used to determine the composition of the film.

Abstract

Purpose

The purpose of this paper is to investigate the effects of knowledge management (KM) on product and process innovations, as well as on operational performance (OP). In addition, the effects of product and process innovations on OP, as well as their mediating effects on the relationship between KM and OP, are also investigated.

Design/methodology/approach

A questionnaire-based survey was designed and used to collect data from 207 manufacturing companies operating in the Jordanian capital Amman. To assess construct validity, exploratory and confirmatory factor analyses were conducted. To test research hypotheses, the bootstrap re-sampling method was applied using Hayes’s SPSS multiple-mediator PROCESS macro.

Findings

The results indicate that KM has significant positive effects on product and process innovations, and OP. Process innovation was found to have a significant positive effect on OP, while product innovation was not. Furthermore, only process innovation was found to significantly mediate the KM-OP relationship.

Practical implications

The findings of this study provide useful insights about the role of KM in facilitating and enhancing product and process innovations, as well as OP in the surveyed manufacturing companies. An important implication concerns the roles of product and process innovations. Manufacturing companies seeking improvements in their OP are recommended to focus on process innovation rather than product innovation. While product innovation may affect other aspects of performance, such as market and financial ones, it was not found to significantly affect OP. Process innovation can also leverage KM’s contribution to manufacturing companies’ OP.

Originality/value

This is a pioneering study in that it developed an integrated model that depicts the interrelationships among KM, product innovation and process innovation and OP, in a developing country context.

Abstract

Discusses the results of impedance measurements done for titanium metal in methanolic 1M HCl containing 0,1,3 and 5 volume per cent H2O. Titanium metal behaved actively in such solutions and became passive when a sufficient amount of water (5 per cent) was present. As a result of anodic oxidation a porous layer has been formed at the metal surface, characterized by the presence of an additional maximum in the phase angle curves. The radii of the pores were calculated from a kugel diffusion impedance element.

Abstract

Purpose

Green product innovation is a global industrial concern. This research examines the possible impact of green product innovation on firms' competitive advantage in industrial enterprises operating in qualified industrial zones (QIZs).

Design/methodology/approach

This research follows a descriptive analytical methodology, testing two hypotheses formulated based on the reviewed literature among chemical industrial plants of the three Jordanian QIZs (Amman, Zarqa and Irbid) in Jordan. Following a preliminary scoping study of all 219 Jordanian chemical manufacturers, a quantitative five-point Likert scale questionnaire was administered to firms applying green product activities.

Findings

In total, 20 firms were found to be utilizing green product innovation, representing only 9.13% of the overall population. The hypothesis testing results indicated that green product innovation has a statistically significant positive impact on competitive advantage. The results also showed that the factor “firm resources” has a statistically significant positive moderation effect on the relationship between green product innovation and competitive advantage.

Research limitations/implications

The vast majority of Jordanian chemical manufacturers were not implementing green innovation or practices; further study is needed to identify barriers. Findings are limited to managers of chemical industrial plants in Jordan, excluding the demand side (e.g. plant customers who purchase final products), which leaves a different research angle to be explored.

Originality/value

This is a pioneering study of green product innovation implications for firm competitive advantage in manufacturing enterprises, especially in QIZs of Jordan (which offer tax exemptions to foreign and local investors and sell products to regional and international markets).
